When clamping the bridge housing 4, the half-shaft sleeves at both ends of the bridge housing 4 are placed on the V-shaped groove. The opening of the sliding groove 3012 improves the stability of the mounting seat 302 moving within the mounting frame 301. Sliding grooves are provided on the front and rear sides of the square through groove 3013. A slider is fixedly installed on the front and rear sides of the driven rack 3014. The slider is installed on the sliding groove to improve the smoothness of the driven rack 3014 moving left and right. One end of the L-shaped pressure plate 3015 is fixedly connected to the driven rack 3014. As the driven rack 3014 moves left and right, the fixing bolt 3016 is used to fix the mounting seat 302, improving the stability of the clamping mechanism 3.

[0028] As a preferred option, it remains as follows Figure 3As shown, in this embodiment, the mounting base 302 has a mounting groove 3021 on the side near the bridge housing 4. A hydraulic cylinder 3022 is fixedly mounted on the top of the mounting groove 3021 on the mounting base 302. A clamping block 3011 is fixedly mounted on the top of the piston rod of the hydraulic cylinder 3022 through the mounting base 302. The clamping block 3011 is located at the top of the mounting groove 3021. A mounting through groove 3023 is opened through the front and rear sides of the mounting base 302.

[0029] Specifically, the hydraulic cylinder 3022 is located directly above the mounting groove 3021 and is mounted on the top of the mounting base 302. The clamping block 3011 on the mounting base 302 is located on the top of the mounting groove 3021, and its top is fixedly connected to the piston rod of the hydraulic cylinder 3022. The bottom of the clamping block 3011 on the mounting base 302 has an inverted V-shaped slot, which corresponds to the V-shaped slot on the clamping block 3011 on the mounting base 302. The mounting through groove 3023 is opened through the front and rear sides of the mounting base 302 for the installation of the rack 3024. The threaded hole 3025 on the mounting base 302 corresponds in height to the fixing bolt 3016.

[0030] As a preferred option, it remains as follows Figure 3 As shown, in this embodiment, the clamping mechanism 3 further includes a driven shaft 304 rotatably mounted on the mounting frame 301. A first gear 305 is fixedly mounted at the middle position of the driven shaft 304, and a second gear 306 is fixedly mounted at both ends of the driven shaft 304. The first gear 305 meshes with the drive rack 3024, and the second gear 306 meshes with the driven rack 3014.

[0031] Specifically, the driven shaft 304 is located in the mounting slot 3023 of the mounting base 302, and its two ends are rotatably mounted on the front and rear sides of the mounting frame 301. The first gear 305 is fixedly mounted in the middle position of the driven shaft 304. Under the action of the drive rack 3024, the first gear 305 rotates. The first gear 305 drives the driven shaft 304 and the second gears 306 at both ends of the driven shaft 304 to rotate. Under the drive of the second gear 306, the driven rack 3014 moves left and right.

[0032] As a preferred option, it remains as follows Figure 1 and Figure 2 As shown, in this embodiment, a driven gear 203 is fixedly installed at the middle position of the outer ring of the rotating table 201, and auxiliary wheels 5 are rotatably installed on both sides of the bottom of the rotating table 201. The auxiliary wheels 5 are fixedly installed on the worktable 1.

[0033] Specifically, the driven gear 203 is fixedly installed in the middle of the outer ring of the rotating table 201. The driven gear 203 drives the rotating table 201 to work. The auxiliary wheel 5 is fixedly installed on the worktable 1, and a set is installed on each side of the bottom of the rotating table 201 to assist the rotation of the rotating table 201.

[0034] As a preferred option, it remains as follows Figure 1 As shown, in this embodiment, a rotating shaft 204 is fixedly provided at the output end of the motor 202, a reducer 205 is fixedly provided between the motor 202 and the rotating shaft 204, and a drive gear 206 is fixedly provided at both ends of the rotating shaft 204, and the drive gear 206 meshes with the driven gear 203.

[0035] Specifically, the rotating shaft 204 extends horizontally through the worktable 1 and is rotatably mounted on the worktable 1. The reducer 205 is connected between the motor 202 and the rotating shaft 204, reducing the output speed of the motor 202 while increasing the output torque of the motor 202. The drive gear 206 is fixedly mounted at both ends of the rotating shaft 204. As the rotating shaft 204 rotates, it simultaneously drives the driven gears 203 on the two rotating tables 201 to rotate, so that the two rotating tables 201 rotate synchronously.

[0036] like Figure 1 The image shows the positions of the mounting base 302 and the L-shaped pressure plate 3015 after the bridge housing 4 is fixedly installed on the clamping mechanism 3.

[0037] Working principle: Before the clamping mechanism 3 operates, the piston rod of the cylinder 303 is in a retracted state. At this time, the clamping block 3011 on the mounting base 302 is located between the clamping block 3011 on the mounting frame 301 and the rotating table 201. At this time, there are no other objects obstructing the clamping block 3011 on the mounting base 302. When the axle housing 4 needs to be welded, the half-shaft sleeves at both ends of the axle housing 4 are first placed on the V-shaped groove of the clamping block 3011 on the mounting frame 301. At this time, the cylinders 303 in the clamping mechanism 3 at both ends of the axle housing 4 are started simultaneously, pushing the mounting base 302 to move closer to the axle housing 4. At this time, the drive rack 3024 on the mounting base 302 drives the first gear 305 to rotate while moving, thereby driving the driven shaft 304 and the second gear 306 at both ends of the driven shaft 304 to rotate. Driven by the second gear 306, the driven rack 3014 moves away from the axle housing 4. Simultaneously, the L-shaped pressure plate 3015 on the driven rack 3014 moves, causing one end of the L-shaped pressure plate 3015 to press against the flanges at both ends of the axle housing 4. The cylinder 303 stops working. At this time, the hydraulic cylinder 3022 and the clamping block 3011 on the mounting base 302 move to the top of the clamping block 3011 in the mounting frame 301. At this time, the fixing bolt 3016 is installed on the threaded hole 3025 on the mounting base 302, fixing the mounting base 302. The hydraulic cylinder 3022 starts, pushing the clamping block 3011 at the top of its piston rod to move downward, so that the upper and lower clamping blocks 3011 clamp the half-shaft sleeve of the axle housing 4. The motor 202 is started. According to the needs of the welding work, under the drive of the motor 202, the rotating table 201 on the drive mechanism 2 drives the clamping mechanism 3 to start rotating, thereby driving the axle housing 4 to rotate to a suitable angle for welding, ensuring that each surface of the axle housing 4 can be welded.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
