The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0023] The first embodiment of the present application is:

[0024] See also Figure 1-Figure 4 ,in Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model; Figure 2 It is a partial cross-sectional view of the rotating table of the first embodiment of the utility model; Figure 3 It is a schematic structural diagram of a clamping member of the first embodiment of the utility model; Figure 4 It is a structural schematic diagram of the clamping block of the first embodiment of the utility model.

[0025] The utility model provides a denture repair spot welding device: comprising a work box 101, a work table 102, a welding gun 103 and a fixing mechanism, the fixing mechanism comprising a tilting seat 110, a tilting arm 111, a tilting motor 112, a rotating assembly and a fixing assembly, the fixing assembly comprising a rotating table 104 and two clamping members, the rotating assembly comprising a rotating motor 108 and four auxiliary balls 109, the clamping member comprising a hydraulic cylinder 105, a connecting block 106 and a clamping block, the clamping block comprising a mounting block 113, two springs 114, two clamping blocks 115, two protective pads 116 and a micro motor 107, the above-mentioned scheme solves the problem that the above prior art cannot clamp and fix the denture, and when the denture is spot welded, the denture will shake, which will lead to the occurrence of false welding and wrong welding.

[0026] According to this specific embodiment, the workbench 102 is fixedly connected to the top of the workbox 101, the welding gun 103 is located on one side of the workbench 102, the tilting seat 110 is fixedly connected to the top of the workbench 102, the tilting arm 111 is rotatably connected to one side of the tilting seat 110, the output end of the tilting motor 112 is fixedly connected to the tilting arm 111, the tilting arm 111 is provided with a rotating cavity and a rotating groove on the side away from the tilting seat 110, the rotating assembly is located in the rotating cavity, the rotating table 104 is rotatably connected to the tilting arm 111, and is located on the side away from the tilting seat 110, the two clamping members are located on one side of the rotating table 104, and are arranged opposite to each other, the hydraulic cylinder 105 is fixedly connected to the rotating table 104, and is located on the side away from the tilting arm 111, and the connecting block 106 is fixedly connected to the At the output end of the hydraulic cylinder 105, the clamping block is located above the connecting block 106. When the denture is spot-welded and repaired, the two hydraulic cylinders 105 are started, and the output ends of the two hydraulic cylinders 105 push out the two connecting blocks 106, driving the two clamping blocks to approach each other. After the distance between the two clamping blocks is appropriate, the denture is clamped on the two clamping blocks. At this time, the tilting motor 112 can be started to rotate the tilting arm 111, driving the fixing assembly and the denture to rotate, thereby changing the inclination of the denture, and starting the welding machine body. The side of the denture close to the welding gun 103 is repaired through the welding gun 103. After the repair of the side of the denture close to the welding gun 103 is completed, if other sides of the denture need to be repaired, the denture can be directly rotated through the rotating assembly, so that the denture does not need to be clamped and fixed multiple times to repair other sides.

[0027] Among them, the rotating motor 108 is fixedly connected to the tilting arm 111 and is located in the rotating cavity, and the output end is fixedly connected to the bottom of the rotating table 104. The bottom of the rotating table 104 is provided with four ball grooves. The four auxiliary balls 109 are rotatably connected to the rotating table 104, and each of the auxiliary balls 109 is located in each of the ball grooves. The four auxiliary balls 109 are slidably connected to the tilting arm 111 and are located in the rotating grooves. When adjusting the angle of the denture, the rotating motor 108 is started, and the output end of the rotating motor 108 drives the rotating table 104 to rotate. With the assistance of the four auxiliary balls 109 located in the rotating grooves, the rotation of the rotating table 104 is more stable and easy, which can reduce the energy consumption of the rotating motor 108. After the denture rotates to the required angle, the rotating motor 108 is turned off, and the angle adjustment of the denture is completed. Through the above operations, the denture can be repaired in multiple directions without multiple clamping and fixing.

[0028] Secondly, the mounting block 113 is rotatably connected to the top of the connecting block 106 and is provided with two spring grooves. The two springs 114 are fixedly connected to the mounting block 113 and are respectively located in the two spring grooves. Each clamping block 115 is fixedly connected to each spring 114 and is slidably connected to the mounting block 113 and is respectively located in the two spring grooves. When clamping and fixing a single denture, the two hydraulic cylinders 105 are started, and the spacing between the two mounting blocks 113 is adjusted according to the size of the single denture. Then, the four clamping blocks 115 in pairs are pulled apart, and the single denture is placed between the four clamping blocks 115. Under the pulling force of the four springs 114, the four clamping blocks 115 clamp the single denture, and the fixation of the single denture is completed, thereby clamping single dentures of different sizes by adjusting the spacing between the two mounting blocks 113.

[0029] At the same time, each of the protective pads 116 is fixedly connected to the surface of each of the clamping blocks 115. A motor slot is provided above the connecting block 106. The micro motor 107 is fixedly connected to the connecting block 106 and is located in the motor slot. When clamping the denture, the protective pad 116 contacts the denture instead of the clamping block 115, which can effectively prevent the denture and the clamping block 115 from wearing due to friction. If the clamping target is a full denture, two of the micro motors 107 need to be started at this time, and the angles of the two mounting blocks 113 are adjusted according to the angles on both sides of the full denture, so that the four clamping blocks 115 can clamp full dentures of different sizes.

[0030] When spot welding the denture, it is necessary to observe the size and type of the denture, start the two hydraulic cylinders 105, and the output ends of the two hydraulic cylinders 105 push out the two connecting blocks 106, driving the two clamping blocks to approach until the distance between the two clamping blocks is appropriate. If the target is a single denture, the four clamping blocks 115 in pairs are pulled apart, and the single denture is placed between the four clamping blocks 115. Under the pulling force of the four springs 114, the four clamping blocks 115 clamp the single denture, and the fixation of the single denture is completed. If the clamping target is a full denture, it is necessary to start the two micromotors 107, and adjust the angles of the two mounting blocks 113 according to the angles on both sides of the full denture, so that the four clamping blocks 115 can clamp full dentures of different sizes; if multi-directional spot welding of the denture is required, the tilting motor 112 and the rotating motor 108 can be started to rotate the tilting arm 111, drive the fixing assembly and the denture to rotate, thereby changing the inclination of the denture, and the output end of the rotating motor 108 drives the The rotating table 104 rotates, thereby driving the two clamping members to rotate, so that the denture rotates coaxially with the rotating table 104, thereby adjusting the position and angle of the denture, so that the device can perform multi-directional spot welding on the denture; at the same time, with the assistance of the four auxiliary balls 109 located in the rotating groove, the rotation of the rotating table 104 is more stable and easy, which can reduce the energy consumption of the rotating motor 108; after the position and angle are adjusted, the welding machine body is started, and the denture is close to the welding gun 103. One side of the welding gun 103 is repaired. After the repair of the side of the denture close to the welding gun 103 is completed, if it is necessary to repair the other sides of the denture, the tilting motor 112 and the rotating motor 108 can be directly started to adjust the position and angle of the denture, so that the denture does not need to be clamped and fixed multiple times before repairing the other sides. This avoids the problem that the prior art cannot clamp and fix the denture, and the denture will shake during spot welding, which will lead to the occurrence of cold welds and wrong welds, thereby achieving the effect of improving the accuracy of the device.

[0031] The second embodiment of the present application is:

[0032] See also Figure 5-Figure 7 ,in Figure 5 It is a schematic diagram of the overall structure of the second embodiment of the utility model; Figure 6 It is a structural schematic diagram of the scale ring of the second embodiment of the utility model; Figure 7 It is a partial cross-sectional view of the scale cover of the second embodiment of the utility model.

[0033] On the basis of the first embodiment, the denture repair spot welding device of this embodiment further includes an auxiliary mechanism, which includes a scale ring 201 , an indicator needle 202 , a scale cover 203 and an indicator shaft 204 .

[0034] Among them, the scale ring 201 is fixedly connected to the tilting arm 111 and is located on a side away from the tilting seat 110. The scale ring 201 is made of transparent material and has an inner cylindrical surface provided with a pointer groove. The pointer 202 is fixedly connected to the rotating table 104 and is located in the pointer groove. When the rotating table 104 rotates, the pointer 202 rotates with the rotating table 104. At this time, the specific rotation angle of the rotating table 104 can be observed through the scale ring 201. At the same time, the scale ring 201 can protect the pointer 202 to prevent the pointer 202 from being damaged by sparks generated during welding.

[0035] Secondly, the scale cover 203 is fixedly connected to the tilt seat 110, and is located on the side away from the tilt motor 112, and is made of transparent material. The index shaft 204 is fixedly connected to the tilt arm 111, passes through the tilt seat 110, and is located in the scale cover 203. When the tilt arm 111 rotates, the index shaft 204 rotates with the tilt arm 111. At this time, the angle swept by the index shaft 204 can be observed through the scale cover 203, and the angle is the rotation angle of the tilt arm 111. At the same time, the scale cover 203 can protect the index shaft 204 to prevent the index shaft 204 from being damaged by sparks generated during welding.

[0036] When the denture repair spot welding device is working, the pointer 202 will rotate with the rotating table 104, and the pointer shaft 204 will rotate with the tilting arm 111, which can be observed through the scale ring 201 and the scale cover 203. The angle swept by the pointer 202 is the rotation angle of the rotating table 104, and the angle swept by the pointer shaft 204 is the rotation angle of the tilting arm 111. The specific rotation angles of the tilting arm 111 and the rotating table 104 can be observed, thereby improving the accuracy of the device.
