[0002] In the automotive manufacturing industry, when assembling and welding the air filter housing on an automobile to achieve the overall connection of the air filter, a welding jig is required to cooperate for fixing it.

[0003] The utility model patent application document with the publication number of "CN206140030U" discloses a welding jig for an air filter housing for automobiles, which mainly consists of a welding device and a clamping device. This technical solution has the advantage of high efficiency, and solves the problems in the existing welding of air filter housings, such as usually welding by manually using a soldering iron, with more human factors involved, large welding errors, high consumption of vulnerable parts, large deviation in temperature control, long time consumption, low efficiency, and high product defect rate.

[0004] The welding jig for an air filter housing for automobiles disclosed in the above document has the following defects: during the use of the clamping device, the clamped filter housing inside the clamping device needs to be welded at multiple angles, and the filter housing cannot be turned. Since the clamping device is fixed on the fixing plate, the welding process is rather troublesome.

[0005] It can be seen that the existing welding jig for an air filter housing does not have a structure convenient for turning, and it is necessary to improve the existing deficiencies to provide a welding jig for an air filter housing. Content of the Utility Model

The workbench 1 includes a bottom plate 101. Table legs 105 are installed at the four corners of the bottom plate 101. A mounting seat 102 is rotatably connected to the outer surface of the bottom plate 101. A first limiting structure 103 is installed on the outer surface of the mounting seat 102. A second limiting structure 104 is installed on the other surface of the mounting seat 102. A bracket 2 is installed on one side of the bottom plate 101. A through hole is opened on the outer surface of the mounting seat 102. A first connecting rod 106 is installed inside the through hole. One end of the first connecting rod 106 is installed with a second connecting rod 107. The other end of the second connecting rod 107 is rotatably connected to a third connecting rod 108. The other end of the third connecting rod 108 is rotatably connected to a fourth connecting rod 109. The other end of the fourth connecting rod 109 is connected to one end of a push rod 1011 through a hinge structure 1010. The other end of the push rod 1011 penetrates through one side of the workbench 1 until it reaches the outside thereof.

[0027] The bracket 2 includes support rods 201. The support rods 201 are set to be two and are symmetrically distributed on the outer surface of the bottom plate 101. A mounting plate 202 is installed on the outer surface of the support rods 201. A through hole is opened on the outer surface of the mounting plate 202. A bearing 203 is installed inside the through hole. The inner and outer surfaces of the bearing 203 are rotatably connected to the outer surface of a hydraulic rod 204. A pressing plate 205 is installed on the lower outer surface of the hydraulic rod 204.

[0028] The first limiting structure 103 includes a first fixing plate 10301. Two first reinforcing plates 10302 are installed on one side of the first fixing plate 10301. A sleeve 10303 is installed between the first reinforcing plates 10302. A through hole is opened on one side of the first fixing plate 10301. The inner and outer surfaces of the through hole are fitted with the outer surface of the sleeve 10303. A lead screw 10304 is installed at the axis of the sleeve 10303. One end of the lead screw 10304 is fitted with one end of a connecting block 10305. A cross bar 10306 is installed at one end of the connecting block 10305. The other end of the lead screw 10304 penetrates through the inside of the sleeve 10303 until it is fitted with one side of a first limiting plate 10307. A slide block 10308 is installed on one side of the lead screw 10304. The slide blocks 10308 are set to be two and are evenly distributed on both sides of the lead screw 10304. One side of the slide block 10308 is fitted with one side of the first limiting plate 10307. The other side of the slide block 10308 penetrates through the first fixing plate 10301. The slide block 10308 is slidably connected to the first fixing plate 10301.

[0029] The second limiting structure 104 includes a second fixed plate 10401. Two second reinforcing plates 10402 are installed on one side of the second fixed plate 10401. A support block 10403 is installed on the other side of the second fixed plate 10401. A second limiting plate 10404 is installed on the other side of the support block 10403.

[0030] Both the first limiting plate 10307 and the second limiting plate 10404 are arranged in a semicircular shape.

[0031] A through hole is opened at one end of the mounting plate 202. A connecting pin 206 is installed inside the through hole. The mounting plate 202 is connected to the support rod 201 through the connecting pin 206.

[0032] During use, first, press one side of the filter housing against one side of the second limiting plate 10404. Then hold the cross bar 10306 and drive the lead screw 10304 to rotate synchronously by rotating the cross bar 10306. Then drive the first limiting plate 10307 to move towards the filter housing through the lead screw 10304 until one side of the first limiting plate 10307 fits against the other side of the filter housing. Then start the hydraulic rod 204 and drive the pressing plate 205 to move downward through the hydraulic rod 204 until the pressing plate 205 abuts against the upper outer surface of the filter housing. Through the extrusion of the pressing plate 205, the bottom of the filter housing fits more firmly with the mounting seat 102. At this time, the clamping of the filter housing is completed. When welding at different positions, only need to push the push-pull rod 1011, and then drive the second connecting rod 107, the third connecting rod 108 and the fourth connecting rod 109 connected to the other end of the push-pull rod 1011 to reciprocate, and then drive the first connecting rod 106 to rotate. Then drive the mounting seat 102 to rotate through the first connecting rod 106, and the filter housing can be operated in different directions without the operator walking back and forth. When the welding is completed, retract the hydraulic rod 204 so that the pressing plate 205 no longer presses the filter housing. Then rotate the cross bar 10306 in the reverse direction, drive the lead screw 10304 to rotate synchronously through the cross bar 10306, and then drive the first limiting plate 10307 to move in the reverse direction away from the filter housing through the lead screw 10304 until one side of the first limiting plate 10307 is separated from the other side of the filter housing. At this time, the welded filter housing can be taken out. Through the rotational installation between the mounting seat 102 and the bottom plate 101, when welding at different positions, only need to rotate the mounting seat 102 to quickly adjust the direction of the housing, making the welding process more convenient and fast, and greatly improving the work efficiency.
