[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, the present invention provides an easy-to-maintain resistance welding machine, comprising:

[0024] The frame 1 has a resistance welding machine body 2 fixedly connected to its top. A clamp 3 is movably connected to the top of the frame 1 and the bottom of the resistance welding machine body 2. A connecting box 4 is fixedly connected to both the left and right sides of the frame 1. A movable mechanism 5 is movably connected to the right side of the connecting box 4 through a bearing seat.

[0025] The moving mechanism 5 includes a throttle 51, a bearing plate 52, a fixed rod 53, a sliding plate 54, a bracket 55, a roller 56, a connecting plate 57, and a positioning block 58. The throttle 51 is movably connected to the right side of the connecting box 4 via a bearing seat. The bearing plate 52 is fixedly connected to the left side of the throttle 51, extending into the interior of the connecting box 4. The front and back ends of the right side of the inner wall of the connecting box 4 are fixedly connected to the fixed rod 53. The sliding plate 54 is slidably connected to the left side of the surface of the fixed rod 53. The bracket 55 is fixedly connected to the right end of the sliding plate 54 away from the fixed rod 53. The roller 56 is movably connected to the inner side of the bracket 55 via a rotating shaft. The right side of the roller 56 contacts the left side of the bearing plate 52. The connecting plate 57 is fixedly connected to the left end of the sliding plate 54 away from the fixed rod 53. The positioning block 58 is fixedly connected to the left side of the connecting plate 57. The left side of the positioning block 58 extends through the left side of the connecting box 4. The front and back ends of the bottom of the inner wall of the connecting box 4 are fixedly connected to a limit mechanism 6.

[0026] refer to Figure 3 The limiting mechanism 6 includes a support 61, a rectangular plate 62, and a slider 63. The support 61 is fixedly connected to the front end and the back end of the bottom of the inner wall of the connecting box 4. The right side of the support 61 is fixedly connected to the left side of the fixing rod 53. The rectangular plate 62 is fixedly connected to the left side of the support 61. The slider 63 is fixedly connected to the front end of the positioning block 58. The front end of the slider 63 is slidably connected to the back end of the rectangular plate 62.

[0027] As a technical optimization of this utility model, by setting the limiting mechanism 6, the slider 63 can follow the positioning block 58 to move, and the slider 63 moves stably along the surface of the rectangular plate 62.

[0028] refer to Figure 4 A sleeve block 7 is fixedly sleeved on the right side of the surface of the fixing rod 53, and trapezoidal blocks 8 are fixedly connected to the top and bottom of the tile 52.

[0029] As a technical optimization of this utility model, the setting of the sleeve block 7 and the trapezoidal block 8 can assist the plate 52 in working and at the same time play a limiting role, so as to prevent the plate 52 from rotating too much and failing to move the roller 56 effectively.

[0030] refer to Figure 5 A groove 9 is provided on the surface of the rectangular plate 62 at the position corresponding to the slider 63. The groove 9 is used in conjunction with the slider 63.

[0031] As a technical optimization of this utility model, by setting the slide groove 9, the slider 63 can move left and right inside the slide groove 9, and at the same time, it plays a limiting role, avoiding the phenomenon of slider 63 deviating during the movement.

[0032] refer to Figure 4A return spring 10 is sleeved on the surface of the fixing rod 53. The left and right sides of the return spring 10 are fixedly connected to the surface of the fixing rod 53 and the left side of the slide plate 54, respectively.

[0033] As a technical optimization of this utility model, the reset spring 10 can assist the slide plate 54 in working and also play a role in reset buffering, thus preventing the slide plate 54 from failing to reset after moving, which would cause the machine to stop working continuously.

[0034] refer to Figure 4 Triangle plates 11 are fixedly connected to the front and back ends of the right side of the support 61, and the top of the triangle plates 11 is fixedly connected to the bottom of the trapezoidal block 8.

[0035] As a technical optimization of this utility model, the triangular plate 11 can increase the strength and avoid the phenomenon of deformation and breakage of the support 61 due to excessive load.

[0036] The working principle and usage process of this utility model are as follows: During use, the handle 51 is manually rotated counterclockwise. The rotation of the handle 51 causes the plate 52 to rotate. The rotation of the plate 52 causes the roller 56 to contact different positions, allowing it to penetrate deeper into the edge of the plate 52. During the rotation of the plate 52, the trapezoidal block 8 moves synchronously. When the trapezoidal block 8 rotates 90 degrees and contacts the sleeve block 7, it stops the plate 52 from rotating further, achieving a positioning function and preventing the plate 52 from rotating too much. Then, the roller 56 moves to the left, causing the bracket 55 and the sliding plate 54 to move synchronously. The sliding plate 54 moves stably along the surface of the fixed rod 53, pulling the return spring 10. As the machine extends, the slide plate 54 moves to the left, causing the connecting plate 57 and the positioning block 58 to move accordingly. During the movement of the positioning block 58, the slider 63 moves smoothly along the slide groove 9 inside the rectangular plate 62. Then, the positioning block 58 moves to the left and disengages from the side of the clamp 3, releasing the clamp 3 from its fixation. The clamp 3 is no longer fixed by the positioning block 58, allowing it to be disassembled. Finally, the maintenance personnel can obtain more space on the surface of the frame 1 to perform maintenance on the resistance welding machine body 2. Similarly, the clamp 3 is placed back in its original position and re-fixed. The handle 51 is rotated clockwise to reinstall and fix the positioning block 58 on the clamp 3.

[0037] In summary, this easy-to-maintain resistance welding machine, through the coordinated use of frame 1, resistance welding machine body 2, clamp 3, connecting box 4, movable mechanism 5, throttle 51, bearing plate 52, fixing rod 53, sliding plate 54, bracket 55, roller 56, connecting plate 57, positioning block 58 and limiting mechanism 6, solves the problem that in existing welding machines, maintenance personnel need to operate on the table, but the protruding fixtures on the table occupy space and make operation inconvenient.
