According to the gas spring mounting jig, the plurality of jig base plates are introduced to form the jig base plate group, and the jig base plates are skillfully related and matched with the centering mechanism and other structures, so that the occupied space of the jig can be effectively reduced, and the gas spring can be effectively positioned and fixed from three directions of length, width and height, so that the mounting quality and the mounting efficiency can be greatly improved.

The embodiment also provides a mounting method of the gas spring mounting jig, which is based on the gas spring mounting jig described in any one of the above schemes, so the foregoing description of the gas spring mounting jig can be cited herein in its entirety.

Specifically, the mounting method of the gas spring mounting jig provided by the embodiment includes the following steps:

1) Providing the gas spring mounting jig described in any one of the above aspects;

2) Placing a gas spring 105 between the rear mount 107 and the front mount 104e, the piston rod joint 105d being fixed to the rear mount 107 such that the axial direction of the gas spring 105 is parallel to the longitudinal direction;

3) Adjusting the centering mechanism 102 so that the centering plate 102a clamps the gas spring 105 from the width direction;

4) By adjusting the position of the slider 104d on the screw 104c, the front support 104e is clamped with the sleeve joint 105a, and the gas spring 105 is compressed to a gas spring stroke required for installation;

5) And moving the gas spring mounting jig to the mounting position of the gas spring 105, and after the gas spring 105 is mounted, loosening the fixing of the rear support 107, the front support 104e and the centering plate 102a to separate the gas spring 105 from the gas spring mounting jig.

In step 1), please refer to fig. 1, a gas spring installation jig according to the present embodiment is provided, and each part of the gas spring installation jig is as described in the foregoing description of the present embodiment.

In one example, the free length of the gas spring to be mounted in this embodiment is 400mm, its nominal force is 900N, and the mounting requirement of the gas spring is to be mounted at a designated position of the semiconductor device after 20mm of compression. In this embodiment, three jig bottom plates 101 are selected, and are mounted by mutually matching the convex grooves and the concave grooves, and are fixed by the through holes 101e and the second threaded holes 101b by using at least 4 fastening screws, so that a jig bottom plate group with the length similar to that of the gas spring is obtained, and after the mounting, each jig bottom plate 101 is ensured to be parallel to each other. The rear support 107 is fixed on the jig base plate 101 through a guide post 108, and the position of the rear support in the height direction is adjusted through an adjusting screw and the guide post 108, and the axes of the guide post 108 and the adjusting screw are located on the same plane. The actuator 104 is fixed to the jig base plate 101 by not less than 4 fastening screws. At least two centering mechanisms 102 are fixed to the jig base plate 101 by fastening screws, one of which is close to the inner side of the actuator 104 and the other of which is close to the inner side of the lower support 107. The height supporting frame 103 is installed in a top groove of the screw supporting seat 104a, and the height thereof can be adjusted by adjusting screws.

In step 2), the gas spring 105 is placed between the rear mount 107 and the front mount 104e, and the piston rod joint 105d is fixed to the rear mount 107 such that the axial direction of the gas spring 105 is parallel to the longitudinal direction. As an example, the sleeve 105b of the gas spring 105 is mounted on the height supporting frame 103, and the height is adjusted by adjusting the corresponding adjusting screw, so that the axis of the gas spring 105 is parallel to the jig base plate 101.

In step 3), the centering mechanism 102 is adjusted so that the centering plate 102a sandwiches the gas spring 105 from the width direction. Specifically, as shown in fig. 1, in the two centering mechanisms 102, one of which holds the sleeve 105b and the other holds the piston rod joint 105d so that the axis of the gas spring 105 is collinear with the center of the spherical recess of the front mount 104 e. After the position is determined, the position of the gas spring 105 is fixed by tightening the adjustment screw. As an example, the position of the gas spring 105 is further secured by fixing the height presser 106 to the top of the centering plate 102 a. At this time, the gas spring 105 is positioned and fixed in three directions of length, width and height.

In step 4), the front mount 104e is caused to clamp the socket joint 105a by adjusting the position of the slider 104d on the lead screw 104c, and the gas spring 105 is compressed to a gas spring stroke required for installation. In this embodiment, the gas spring 105 is required to be installed after compressing the gas spring stroke by 20 mm. Therefore, when the position of the slider 104d on the screw 104c is adjusted so that the front mount 104e contacts the gas spring 105 in the uncompressed original state, the position of the slider 104d on the screw 104c is recorded and marked as 0mm, the position of the slider 104d on the screw 104c is further saved, the front mount 104e is made to clamp the socket joint 105a, and further compressed by 20mm, so that the gas spring is compressed to the gas spring stroke required for installation.

In step 5), the gas spring mounting jig is moved to a mounting position of the gas spring 105, for example, a designated position where the gas spring is reserved to be mounted on the semiconductor device, and after the gas spring 105 is mounted, the fixing of the rear mount 107, the front mount 104e, and the centering plate 102a is released, so that the gas spring 105 is separated from the gas spring mounting jig. Thus, the installation of the gas spring is completed.

In other examples, for the gas springs with different lengths, the number of the jig base plates can be changed to adapt to the gas springs with different lengths, so that the structure of the gas spring mounting jig is more compact, the size of the mounting jig is reduced, the modularized jig is higher in design universality and matching performance, and different use scenes can be matched; and the modularized components can be flexibly disassembled after being used, so that the transportation and storage are convenient. Because the actuating mechanism is arranged on one side of the gas spring, the length of the screw rod is reduced, the cost of the jig is reduced, and the operation time of clamping and compressing the gas spring is shorter. The gas spring mounting jig can position and fix the gas spring from three different dimensions of length, width, height and the like, reduces the risk of sliding and falling off of the gas spring, is safer and more efficient to mount, and can accurately adjust the compression stroke of the gas spring in the length direction. According to the invention, by introducing the modularized front support and the modularized rear support, the gas springs with different joints can be adapted by only replacing the front support and the rear support with corresponding joint surfaces. In addition, the modularized fixture bottom plate also supports other components with special requirements for installation. The gas spring mounting jig of the invention remarkably reduces the occupied space through the modularized design, thereby having obvious advantages in semiconductor equipment with smaller mounting space. Due to the fact that the gas spring installation jig provided by the embodiment is used, the installation of a complex gas spring can be simpler, the installation reworking is reduced, and the installation quality and the installation efficiency are ensured.

In this embodiment, two jig base plates are selected to form a jig base plate group.
