For example, Chinese Patent Publication No. CN115296139B discloses a COS assembly method and assembly equipment based on a modular base, which provides a clamping fixture. This clamping fixture has several support grooves for supporting the modular insulating base, and each support groove has a useful... The first clamping assembly for the COS module in the modular insulating base includes a lifting rod that is movably mounted on a support base. The lifting rod is located on the outer side of the end of the bearing groove, and its top extends upward toward the space above the bearing groove to form a horizontal support portion. A clamping member for holding the COS module is provided on the horizontal support portion. This solution can achieve the clamping of the COS module.

Detailed Implementation Methods

[0025] Please refer to Figures 1-4This embodiment is a general-purpose clamping fixture. The general-purpose clamping fixture 100 includes a fixture body 1 for positioning the product, a mounting beam 2 arranged along the length direction of the fixture body 1 and located above the fixture body 1, and a plurality of clamping modules 3 that are movably arranged on the mounting beam 2 and used to clamp the product.

[0026] In this embodiment, the product refers to the assembly of the COS module and the base. In other embodiments, other products can be pressed together, and the specific products are not limited.

[0027] The fixture body 1 is provided with several positioning holes 11 and threaded holes 12. Selectively, first positioning pins are provided in some of the positioning holes 11 and / or first screws are selectively provided in some of the threaded holes 12 to achieve positioning of products of different sizes, thus increasing versatility. Specifically, when a product is positioned on the fixture body 1, any of the following positioning methods can be selected according to the product's structure:

[0028] The first positioning method: selectively setting the first positioning pin in some positioning holes 11 to achieve product positioning;

[0029] The second positioning method: selectively setting the first screw in some of the threaded holes 12 to achieve product positioning;

[0030] The third positioning method: selectively setting a first positioning pin in some positioning holes 11 and selectively setting a first screw in some threaded holes 12 to jointly achieve product positioning;

[0031] Due to the different structures of the products, the first positioning pin can be selectively set in the positioning hole 11 at different positions, and the first screw can also be selectively set in the threaded hole 12 at different positions. Therefore, each of the above positioning methods has multiple positioning methods. The positions of the first positioning pin and the first screw are adjusted adaptively according to the different structures of the products, which is not limited here.

[0032] The fixture body 1 has several guide holes 15 for guiding and positioning, facilitating the positioning of the universal clamping fixture 100 onto the machine base (not shown in the figure). Several suction blocks 16 are provided on the back of the fixture body 1. The machine base (not shown in the figure) is equipped with second positioning pins that mate with the guide holes 15 and electromagnets that mate with the suction blocks 16 for suction and positioning. When the electromagnets are energized, they attract and hold the suction blocks 16, thus achieving suction and fixation of the fixture body 1. The guide holes 15 and suction blocks 16 ensure stable positioning of the universal clamping fixture 100 provided in this solution onto the machine base (not shown in the figure). One end of the fixture body 1 has a mistake-proof notch 13, which prevents incorrect use from the front or back.

[0033] Support seats 14 are provided at both ends of the fixture body 1. In this embodiment, two mounting beams 2 are arranged parallel to each other, with both ends of the mounting beams 2 mounted on the support seats 14. Several clamping modules 3 are arranged in a straight line on each mounting beam 2. Therefore, the clamping modules 3 on the two mounting beams 2 are respectively clamped on both sides of the product to achieve double-sided clamping, which can improve the stability during clamping and ensure the accuracy during welding. Of course, the arrangement of the clamping modules 3 can also be changed to achieve three-sided clamping, four-sided clamping, or multi-sided clamping of the product to improve the stability of clamping. As for the specific position of the clamping on the product, it is not limited here.

[0034] In other embodiments, the number of mounting beams 2 can be set according to the actual situation, and the arrangement of the clamping modules 3 on the mounting beams 2 can be adjusted according to the actual situation, which is not limited here.

[0035] In another embodiment, the support base 14 and the mounting beam 2 can be configured as an integral structure, serving as a mounting base for the clamping module 3. The specific structure can be adjusted according to the actual situation, and the arrangement of the clamping module 3 on the mounting beam 2 can also be adjusted according to the actual situation, without any restrictions.

[0036] The clamping module 3 includes a lifting rod 31 movably mounted on the mounting beam 2, a limiting block 32 mounted on the upper end of the lifting rod 31 and restricted to the upper surface of the mounting beam 2, and a clamping member 33 mounted on the lower end of the lifting rod 31 and pressed against the surface of the product. In this embodiment, the clamping member 33 is a pin. In other embodiments, it can be configured as other clamping structures, which are not limited here.

[0037] The limiting block 32 is fixed to the upper end of the lifting rod 31 by the second screw 34, and the holding member 33 is disposed at the lower end of the lifting rod 31 by the spring piece 35. The lifting rod 31 includes a first lifting part 311 with its upper end vertically arranged and movable up and down on the mounting beam 2, a second lifting part 312 with its lower end vertically arranged and on which the holding member 33 is installed, and a connecting part 313 that connects the first lifting part 311 and the second lifting part 312 and is in a horizontal state.

[0038] The spring piece 33 is fixedly mounted on the connecting part 313. One end of the spring piece 33 extends out of the outer side of the connecting part 313 and is provided with a plurality of first mounting holes for mounting the pressing member 33. The upper end of each pressing member 33 is fixed in the corresponding first mounting hole. In this embodiment, two pressing members 33 are arranged relatively parallel on each spring piece 33 and pressed against the product on both sides of the product, which can ensure the stability during pressing. In other embodiments, the number of pressing members 33 provided on each spring piece 33 is determined according to the actual situation and is not limited here.

[0039] The second lifting part 312 is provided with a second mounting hole 314 for mounting the holding member 33 and a guide limiting hole 315 for guiding and limiting the holding member 33. The upper end of the holding member 33 is fixed on the first mounting hole, extends downward through the guide limiting hole 315, and the lower end is fixed on the second mounting hole 314. The connecting part 313 is provided with a guide rod 316, and a spring 317 is sleeved on the outer periphery of the guide rod 316. The spring piece 33 and the connecting part 313 are both provided with a third mounting hole for mounting the guide rod 316.

[0040] The mounting beam 2 has several through holes 21 that mimic the shape of the first lifting part 311 and several stepped holes 22 for mounting springs 317 along its length. The through holes 21 and stepped holes 22 are arranged in pairs. The lower end of the spring 317 abuts against the spring piece 33, and the upper end abuts against the wall of the stepped hole 22. Since the mounting beam 2 has several pairs of through holes 21 and stepped holes 22 along its length, several corresponding clamping modules 3 can be selectively installed on the mounting beam 2 according to the length of the product. Therefore, the number of clamping modules 3 can be increased or decreased so that the arrangement of the clamping modules 3 corresponds to the product to achieve clamping of products of different sizes, thus improving versatility.

[0041] When using the universal clamping fixture 100 provided in this solution, in the initial state when the product is not clamped, the limiting block 32 is restricted to the upper surface of the mounting beam 2. When the product needs to be clamped, the external mechanism (not shown in the figure) drives the limiting block 32 to move several lifting rods 31 upward, thereby simultaneously lifting several clamping members 33 upward, leaving a gap for placing the product so that the product can be placed onto the fixture body 1. At this time, the spring 317 is compressed. After the product is placed, a first positioning pin is selectively provided in some of the positioning holes 11 and / or selectively... A first screw is installed in part of the threaded hole 12 to position the product. An external mechanism (not shown in the figure) drives the limit block 32 to move the lifting rod 31 downward, so that the holding member 33 is pressed into the corresponding position of the product. At this time, the spring 317 relaxes and the holding member 33 is elastically pressed into the product. The holding member 33 can be elastically pressed into the product by the spring 317, so that the holding member 33 can be adaptively relaxed according to the different flatness of the product surface, so that the COS fits the base more flatly, thereby ensuring the overall flatness of the base during the welding process.

[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
