[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1As shown in the figure, the present invention provides a clamping mechanism for a cylinder liner welding equipment, including a clamping component 100, a feeding component 200, and a fixing component 300. The fixing component 300 is used to fix the cylinder liner 400, the clamping component 100 is used to clamp the welding part 500, the feeding component 200 is used to move the welding part 500 to below the clamping component 100, and a welding component 600 is slidably provided on the fixing component 300. The welding component 600 is used to weld the welding part 500 onto the cylinder liner 400.

[0021] like Figure 2 As shown, the clamping assembly 100 includes a support platform 101, a support back plate 102 fixedly mounted on the support platform 101, a first control box 103 fixedly mounted on the support back plate 102, and a mounting plate 104 slidably mounted on the first control box 103. Figure 3 As shown, a first telescopic cylinder 112 is fixedly mounted on the mounting plate 104. A first connecting member 111 is fixedly mounted on the output end of the first telescopic cylinder 112. Two connecting rods 110 are rotatably mounted on the first connecting member 111. A rectangular groove 106 is fixedly mounted on the mounting plate 104 through the housing 105. A sliding rod 107 is fixedly mounted inside the rectangular groove 106. Two moving blocks 109 are slidably mounted on the sliding rod 107. Both moving blocks 109 are slidably connected to the rectangular groove 106. The two connecting rods 110 are rotatably connected to the moving blocks 109 respectively. A clamping plate 108 is fixedly mounted on each of the two moving blocks 109. The clamping plate 108 is curved. The folding plate has a bending angle greater than 90 degrees. During use, the output end of the first telescopic cylinder 112 is controlled to move up and down, thereby moving the first connecting piece 111 up and down. During the up and down movement of the first connecting piece 111, the rotation of the two connecting rods 110 causes the distance between the two moving blocks 109 and the clamping plates 108 on them to change. As the angle between the two connecting rods 110 increases, the distance between the two clamping plates 108 increases. As the angle between the two clamping plates 108 decreases, the distance between the two clamping plates 108 decreases. When the distance between the two clamping plates 108 decreases, the welding parts 500 can be clamped.

[0022] like Figure 2 As shown, the feeding assembly 200 includes a second control box 201, a second telescopic cylinder 202 is fixedly installed inside the second control box 201, a support plate 203 is fixedly installed at the output end of the second telescopic cylinder 202, and a limiting area 204 is fixedly installed on the support plate 203. In use, the welding accessory 500 is placed in the limiting area 204, and the support plate 203 is pushed to the bottom of the two clamping plates 108 by the second telescopic cylinder 202. With the movement of the mounting plate 104 and the change of the distance between the two clamping plates 108, the two clamping plates 108 clamp the welding accessory 500. Then, the mounting plate 104 is controlled to continue to move downward, and the welding accessory 500 is placed at the welding position of the cylinder liner 400 for welding.

[0023] like Figure 2 As shown, the fixing component 300 includes an end plate 301, a connecting seat 302 fixedly mounted on the end plate 301, a rotating shaft 303 rotatably mounted on the connecting seat 302, and a plurality of inner support rods 304 slidably mounted on the rotating shaft 303. The sliding method of the plurality of inner support rods 304 includes direct pushing by a cylinder, and the driving method of the rotating shaft 303 includes direct driving by a motor. In use, the plurality of inner support rods 304 are retracted, and then the cylinder liner 400 is fitted onto the rotating shaft 303. The plurality of inner support rods 304 slide outward, thereby fixing the cylinder liner 400 from the inside. The fixing assembly 300 also includes a support base 310, which is fixedly connected to the support platform 101. A third mounting block 311 is slidably mounted on the support platform 101 below the support base 310. The sliding connection between the third mounting block 311 and the support base 310 includes a gear and rack meshing transmission, i.e., a gear is rotatably mounted on the third mounting block 311, and a rack is fixedly mounted on the support base 310. A motor drives the gear to rotate, realizing the movement of the third mounting block 311 on the support base 310. A bidirectional threaded rod 308 is rotatably mounted on the third mounting block 311, and a fixed... The limiting rod 309 and the support base 310 are respectively provided with base plates 305 on both sides. The two ends of the bidirectional threaded rod 308 are threadedly engaged with the two base plates 305 respectively, and the two base plates 305 are slidably engaged with the limiting rod 309. The bidirectional threaded rod 308 is driven by a motor. Support members 307 are installed on both base plates 305. A telescopic rod and a spring 306 are provided between the support member 307 and the base plate 305. The two ends of the telescopic rod and the spring 306 are fixedly connected to the support member 307 and the base plate 305 respectively, and the spring 306 is sleeved on the telescopic rod. In use, the motor drives the bidirectional threaded rod 308 to change the distance between the two base plates 305. When the support members 307 on the two base plates 305 approach each other, the two support members 307 and the support seat 310 can support the bottom of the cylinder liner 400. When the third mounting block 311 slides outward, the two support seats 310 can slide outward synchronously. When the inner support rods 304 on the rotating shaft 303 retract, the cylinder liner 400 clamped on them will fall down between the two support members 307. The cylinder liner 400 is clamped by adjusting the distance between the two support members 307, and the welded cylinder liner 400 can be taken out as the third mounting block 311 moves. When the two support members 307 are adjusted toward the position close to the support base 310, the unwelded cylinder liner 400 can be placed directly between the two support members 307. At this time, the two support members 307 play a supporting role. As the support members 307 drive the cylinder liner 400 back to the welding position, the cylinder liner 400 can be fitted onto the rotating shaft 303.

[0024] like Figure 2 and Figure 4As shown, the welding assembly 600 includes a sliding groove 601 disposed on the side of one of the base plates 305. A sliding block 602 is slidably disposed on the sliding groove 601. A first support rod 603 is fixedly disposed on the sliding block 602. A first mounting block 604 is slidably disposed on the first support rod 603. A second support rod 605 is rotatably disposed on the first mounting block 604. A second mounting block 606 is fixedly disposed on the second support rod 605. A welding head 608 is fixedly mounted on the second mounting block 606 via a mounting bracket 607. The sliding method of the sliding block 602 and the first mounting block 604 includes the movement of the sliding block 602 and the first mounting block 604 through gear and rack meshing transmission. Specifically, both the sliding block 602 and the first mounting block 604 are rotatably disposed on gears, and both the sliding groove 601 and the first support rod 603 are fixedly disposed on racks. The movement of the sliding block 602 and the first mounting block 604 can be realized by the meshing transmission of the gears and racks. The rotation method of the second support rod 605 includes the drive of a motor.

[0025] In use, the welding component 500 is placed on the limiting area 204 on the feeding assembly 200, and then the welding component 500 is clamped by the clamping plate 108 on the clamping assembly 100. Then, the clamping assembly 100 drives the welding component 500 down to the surface of the cylinder liner 400. The position of the welding head 608 is controlled and adjusted, and the welding component 500 is welded to the surface of the cylinder liner 400 in conjunction with the rotation of the rotating shaft 303. Then, several inner support rods 304 are driven to retract, and the welded cylinder liner 400 is clamped by two support members 307. The two support members 307 are slid outward by the third mounting block 311, so that the cylinder liner 400 can be removed from the rotating shaft 303.
