Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, and in particular to an elastic tooling for welding metal filter cover plates. Background Technology

[0002] A filter is a filtering circuit composed of capacitors, inductors, and resistors. A filter can effectively filter out a specific frequency point or frequencies other than that frequency point in a power line to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency. However, when manufacturing a metal filter, the cover plate needs to be welded to the whole to form a whole.

[0003] There is a fixing structure between the filter housing and the cover plate, which allows the cover plate to be placed on the filter housing for easy welding by the staff. However, in actual welding, the staff not only need to operate the welding equipment, but also need to fix the cover plate on the filter housing, which is very inconvenient. At the same time, the filter housing may shake or move, which will affect the welding quality and reduce its quality. Utility Model Content

[0004] To improve welding quality, this application provides a flexible tooling for welding metal filter cover plates.

[0005] The flexible tooling for welding metal filter cover plates provided in this application adopts the following technical solution:

[0006] A flexible tooling for welding metal filter cover plates includes a base and a plurality of first fixing blocks. The base is provided with a plurality of assembly blocks, each assembly block being provided with an assembly groove. The first fixing blocks are slidably disposed in the assembly grooves. An assembly spring connected to the first fixing blocks is disposed in the assembly grooves. The base is provided with a column, and the column is provided with a pressing cylinder. A pressing block is disposed on the piston rod of the pressing cylinder.

[0007] By adopting the above technical solution, the filter housing to be welded is inserted between the assembly blocks, and the first fixing block is pushed to compress the assembly spring. The cover plate is placed on the filter, and the pressing cylinder is activated to push the pressing block to press on the cover plate, thereby lifting the filter and the cover plate. Welding can then be performed. The operation is simple and convenient, and easy to use. The first fixing block lifts the filter housing, and at the same time, the pressing block presses on the cover plate and the filter, thereby completing the positioning of the filter components, reducing the possibility of displacement and shaking during the welding process, and thus improving the welding quality.

[0008] Preferably, the base is slidably provided with two second fixed blocks, and the base is provided with a driving component for driving the second fixed blocks to move.

[0009] By adopting the above technical solution, the second fixing block is driven to move and clamp the filter housing, thereby further improving the stability of the filter housing fixation, reducing the possibility of shaking during the welding process affecting the welding effect, and improving the welding quality.

[0010] Preferably, the drive assembly includes a drive motor, a first drive screw, and a second drive screw. The drive motor is mounted on a base, and the base has a sliding groove. The second fixing block is slidably mounted in the sliding groove. Both the first and second drive screws are rotatably mounted in the sliding groove. The first and second drive screws are connected and their threads are opposite. The drive motor shaft is connected to the first and second drive screws. The first drive screw passes through one second fixing block and is threadedly connected to the second fixing block. The second drive screw passes through another second fixing block and is threadedly connected to the second fixing block.

[0011] By adopting the above technical solution, the drive motor is started to drive the first drive screw and the second drive screw to rotate, thereby driving the two second fixed blocks to move towards or away from each other, thereby clamping or releasing the clamps. The operation is simple and convenient, improving the ease of use.

[0012] Preferably, the second fixing block is provided with an enlarged block, which is disposed outside the sliding groove.

[0013] By adopting the above technical solution, the enlarged block increases the contact area, thereby improving the stability of the filter housing and reducing the possibility of shaking during welding, thus improving the welding quality.

[0014] Preferably, the base is provided with a rotating groove, and a rotating block is rotatably disposed in the rotating groove. The rotating block is disposed directly below the pressing block, and the assembly block and the second fixing block are both disposed on the rotating block.

[0015] By adopting the above technical solution, the filter housing is fixed on the rotating block. After the pressing cylinder is released from pressing, the rotating block can be rotated to drive the filter housing to rotate, thereby changing the welding angle. Then, pressing and welding are carried out, reducing the possibility of welding being interfered with by the column and improving the convenience of welding.

[0016] Preferably, the rotating block is provided with a plurality of positioning blocks, the base is slidably provided with a locking block, the locking block is provided with a locking groove, and the positioning block can be inserted into the locking groove.

[0017] By adopting the above technical solution, after rotating the rotating block to a suitable angle, the locking block can be pushed to slide and the positioning block can be inserted into the locking groove, thereby locking the rotating block and reducing the possibility of the rotating block rotating during the welding process, thus affecting the welding quality.

[0018] Preferably, the base is provided with an auxiliary block, the auxiliary block is provided with an auxiliary groove, the locking block is slidably disposed in the auxiliary groove, and an auxiliary spring connected to the locking block is provided in the auxiliary groove.

[0019] By adopting the above technical solution, when it is necessary to release the lock, the locking block is pushed to slide and compress the locking spring, so that the positioning block is disengaged from the locking groove. The auxiliary spring pushes the locking block to keep the locking groove on the positioning block, thereby improving the stability of the lock.

[0020] Preferably, the locking block is provided with a pushing block.

[0021] By adopting the above technical solution, the ease of pushing the locking block is improved, making it more convenient to use.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a base, a first fixing block, an assembly block, an assembly slot, an assembly spring, a column, a pressing cylinder, and a pressing block, the filter housing is inserted between the base and the first fixing block. The first fixing block is pushed to squeeze the assembly spring in the assembly slot of the assembly block, thereby fixing the filter housing. The cover plate is placed on the filter housing, and the pressing cylinder is activated to push the pressing block to press onto the cover plate, thereby fixing the cover plate and the filter housing. Welding can then be performed, reducing the possibility of displacement and shaking affecting the welding process, thereby improving the welding quality.

[0024] 2. By setting a second fixed block, a sliding groove, a drive motor, a first drive screw and a second drive screw, the drive motor is started to drive the first drive screw and the second drive screw to rotate in the sliding groove, thereby driving the second fixed block to move and clamp the filter housing, further improving the stability of the filter housing fixation;

[0025] 3. By setting a rotating block, a positioning block, a rotating groove, a locking block, and a locking groove, the rotating block is pushed to rotate in the rotating groove, thereby changing the welding angle of the filter housing, which facilitates the welding of the filter. At the same time, after rotation, the locking block is pushed so that the locking groove fits onto the positioning block, thereby locking the rotating block and reducing the possibility of the rotating block rotating during the welding process, which may affect the welding quality.

A crossbar 111 is fixedly mounted on the column 11. A pressing cylinder 112 is fixedly mounted on the crossbar 111. The piston rod of the pressing cylinder 112 passes through the crossbar 111. A pressing block 113 is fixedly mounted on the piston rod of the pressing cylinder 112. The pressing block 113 is positioned directly above the rotating block 6 and can be inserted between the two assembly blocks 2. A sliding groove 61 is provided on the surface of the rotating block 6 between the two assembly blocks 2. Two second fixing blocks 4 are slidably disposed within the sliding groove 61. An enlarged block 41 is integrally fixed to each second fixing block 4 and is located outside the sliding groove 61. The rotating block 6 is provided with a driving assembly 5 for driving the movement of the second fixing blocks 4. The filter housing is clamped by the first fixing block 3 and the second fixing block 4, and the cover plate is pressed onto the filter housing by the pressing block 113, thereby reducing the possibility of displacement and shaking affecting the welding process and improving the welding quality.

[0032] For ease of use, please refer to Figure 1 and Figure 2The drive assembly 5 includes a drive motor 51, a first drive screw 52, ​​and a second drive screw 53. Both the first drive screw 52 and the second drive screw 53 are rotatably mounted in a sliding groove 61.
