The invention relates to the manufacture and testing of springs, namely, devices for improving the quality and performance of the spring by contact samevolume, and can be used in industries that manufacture and use spring - mechanical engineering, aerospace, automotive, instrumentation and other

The known device for contact samevolume springs described in the copyright certificates of the USSR No. 198747, 348792, 419660, 643684.

The closest are devices for contact samevolume springs, AS described in the USSR No. 643684 and 348792.

A device for contact samevolume springs, AS described in the USSR №643684, comprising a fixed plate, a movable plate with guide to install the spring, a ball bearing, a connecting plate, and the sleeve, and the guides are made in the form of plates with slots in which is located the spring, and the end surface of the movable plate is made grooves for moving guides, having a depth exceeding the value of the setting of jumper guides.

A disadvantage of this device is the inability of fixation at senegalian different wire diameter springs.

It should be noted presentely uniform distribution of load samevolume diameter Tanavoli is protected springs, as well as the need to produce thin-walled bushings 7 every time you install a spring with a different size of the outer diameter, the failure to consolidate the bushings 7.

It is also known a device for contact samevolume springs, AS described in the USSR №348792 containing plate, placed her glass to install it tested spring loading mechanism with a device for balancing placed in two glass inserts with screw surface and emphasis, between which is mounted the tested spring, one of the inserts is mounted for rotation about the axis of the Cup, and the other can move along its axis.

A disadvantage of this device is the design complexity and the inability to apply for samevolume springs with other dimensions outside diameter and wire diameter.

An object of the invention is to develop a device that allows you to capture when senegalian different in outside diameter and wire diameter of the spring, and simplify the design of the device.

The technical result is achieved due to the presence of new elements of the device and new relationships, namely: the essence of the invention lies in the fact that the device for contact samevolume springs containing lower fixed p the ITU, punch ball surface in contact with the spherical surface of the upper bearing shell, lower shell, located on the bottom plate, are performed on both liners helical surface with stop and repeat the profile extreme turns of the spring, in addition to the lower fixed plate attached rectangular guides supports that can be reinstalled on the outer diameter of the spring, and the bottom plate is made of radial T-slots for mounting supports.

1 shows a view in plan of the claimed device, figure 2 shows a section a-a of the device.

The device consists of a plug 1 having a spherical surface in the zone of contact with the upper ball liner 2, a rectangular guide bearings 3, attached to the lower fixed plate 4 by bolts and nuts 5. Between the guide bearings on the bottom plate is lower shell 6, which is tested by the spring 7.

At the ends of the liners are made helical surface with emphasis repeating the profile extreme wrap samevolume spring.

Rectangular support extrusions are arranged radially so that the spring is under compression until it touches turns based on them.

The device operates as follows.

The device is installed on the press. The bottom plate 4 is fixed to the table of the press, and PU is non 1 - to the top plate of the press, from which the press force is transmitted to the punch 1. The spring 7 is installed in the device so that it touched at the turns of the screw surfaces of the liners and rested extreme end of turns in the lock liners. When lowering of the punch 1, the spring 7 is compressed to a contact of coils, based on a rectangular support guides 3. In this case, due to the presence of spherical surface on the punch 1 and the upper liner 2 and the helical surfaces on both liners and stops the press force is distributed evenly across the diameter of the spring. After the desired shutter speed under load the spring removed from the device and measure geometric and strength parameters.

An advantage of the claimed device relative to the known is to simplify the design and possible reconfiguration for samevolume springs with other dimensions outside diameter and wire diameter. Made again only inserts required for uniform distribution of load samevolume the diameter of the spring.

This fact allows to consider the proposed design is more economical in manufacture and operation.

Device for contact samevolume springs, containing the punch with the ball surface in contact with the ball p is the upper surface of the liner, the lower shell is located on the lower fixed plate, are performed on both liners helical surface with emphasis repeating the profile extreme turns of the spring, wherein the lower fixed plate attached rectangular guides supports that can be reinstalled on the outer diameter of the spring, and rectangular guides bearings are mounted to the lower fixed plate by means executed by radial T-slots.
