[0016] A fixture maintenance method, which is applicable to the above-mentioned fixture maintenance device, comprises the following steps:

[0017] The first step: placing the clamping pliers, first place the clamping pliers on the movable plate, then rotate the adjusting screw so that the adjusting screw drives the two extrusion plates arranged thereon to approach the clamping pliers through the opposite threads at both ends thereof, so that the extrusion plates slide along the movable plate, thereby making the two extrusion plates close to the surface of the end of the clamping pliers through the flexible member, and continue to rotate the adjusting screw so that the adjusting screw clamps the clamping pliers through the extrusion plate and the flexible member. After the clamping pliers are clamped, the movable plate is driven to move vertically by the fourth electric push rod, so that the movable plate drives the clamped clamp to rise and fall vertically, so that the movable plate adjusts the position height of the clamping pliers, which is convenient for the milling mechanism, welding mechanism and detection mechanism to perform corresponding work on the clamping pliers;

[0018] Step 2: Repair the clamping pliers. After the clamping pliers are clamped and fixed by the extrusion plate, the repair method is first determined according to the damage condition. First, for a structure in which the clamping pliers is flat and only has defects such as potholes, the milling unit is driven by the first electric push rod to approach the clamping pliers after clamping, and by replacing different tools, the milling unit is made to mill the clamping pliers of the flat structure, and at the same time, the support frame is driven to move along the base by the linear drive member, so that the milling unit is made to mill the surface of the clamping pliers, so that the milling unit cuts and removes the potholes on the plane of the clamping pliers; second, for a clamping pliers with a broken or missing planar structure, the welding unit is first driven by the second electric push rod to move close to the clamping pliers, and then the welding unit is made to weld and fill the broken or missing clamping pliers, so that the broken or missing clamping pliers are repaired into a whole, and after the clamping pliers are repaired, the welding unit is driven by the first electric push rod to approach the clamping pliers after the repair, so that the milling unit is made to The clamping clamp after welding is milled so that the milling unit can trim the clamping clamp after welding and patching by the welding unit; thirdly, for a structure in which the clamping clamp is a curved surface and only has defects such as potholes on the surface, the first electric push rod drives the milling unit to approach the clamping clamp after clamping, and by replacing different tools, the milling unit is made to perform milling processing on the clamping clamp of the curved surface structure, and when the milling unit performs milling processing on the clamping clamp of the curved surface structure, the rotating motor drives the driving gear to rotate forward and reverse, so that the driving gear drives the circular arc rack meshing with it to rotate forward and reverse, so that the circular arc rack drives the milling unit to rotate forward and reverse around its rotation center, and then the milling unit drives the milling cutter to repeatedly perform circular arc trajectory movement around the rotation center of the milling unit, and at the same time, the linear drive member drives the support frame to move along the base, so that the milling unit performs milling processing on the curved surface of the clamping clamp, so that the milling unit cuts and removes potholes on the curved surface of the clamping clamp;Fourthly, for the clamping clamp with a broken or missing curved surface structure, the welding unit is first driven by the second electric push rod to move close to the clamping clamp, and then the welding unit is made to weld and fill the broken or missing clamping clamp, so that the broken or missing clamping clamp is repaired into a whole. After the clamping clamp is repaired, the welding unit is driven by the first electric push rod to move close to the clamping clamp after the repair, so that the milling unit mills the welded clamping clamp, and the driving gear is driven by the rotary motor to rotate forward and reverse, so that the driving gear drives the circular arc rack meshed with it to rotate forward and reverse, so that the circular arc rack drives the milling unit to rotate forward and reverse around its rotation center, and then the milling unit drives the milling cutter to repeatedly move in a circular arc trajectory around the rotation center of the milling unit, and at the same time, the support frame is driven by the linear drive member to move along the base, so that the milling unit mills the curved surface of the clamping clamp, so that the milling unit can trim the clamping clamp after welding and filling by the welding unit; and after the welding unit is welded and repaired, the rotating wheel is driven by the driving motor to rotate The rotating wheel drives the connecting rod to swing, so that the connecting rod drives the plunger to move back and forth in the second mounting plate, so that the plunger can flatten the surface of the clamping clamp after welding; when the milling unit trims the clamping clamp, the third electric push rod drives the detection mechanism to approach and fit the trimmed surface of the clamping clamp, so that the detection rod detects the trimmed surface of the clamp, and uses a bubble level to detect and ensure that the surface milled by the milling unit is flat. When the detection rod detects, the motor is adjusted to drive the friction wheel to rotate, so that the friction wheel drives the detection rod The detection rod moves on the lifting plate so that the detection rod can detect the surface after the milling of the milling unit, and the detection rod performs segmented detection on the milled surface through multiple detection segments, so as to keep the milled surface flat at all locations. At the same time, the transmission gear is driven to rotate by the mobile motor. As the transmission gear rotates and engages with racks at different locations, the transmission gear drives the mounting block to move along the detection rod, so that the mounting block drives the detection block to move along the detection rod, so that the detection block detects the surfaces of different locations of the clamping clamp, thereby ensuring that the surface of the clamping clamp after the milling unit is trimmed is flat;

[0019] Step 3: Remove and try it out. After the clamp is repaired, rotate the adjusting screw in the opposite direction so that the adjusting screw drives the extrusion plate away from the clamp, thereby releasing the locking fixation of the clamp by the extrusion plate, making it easier to remove the repaired clamp. After the repaired clamp is removed from the movable plate, install the repaired clamp back into the original fixture and try it out to ensure that the repaired clamp can be used normally.

[0020] In the above technical solution, the beneficial effects of the present invention are:

[0021] 1. The present invention uses a milling mechanism to perform milling processing on the clamping clamp to remove defects such as potholes on the surface of the clamping clamp, and uses a welding mechanism to weld and repair broken or missing clamps, and uses the milling mechanism to mill the welded clamps to ensure the integrity of the clamp repair;

[0022] 2. The present invention detects the surface of the clamping pliers processed by the milling mechanism through the detection mechanism. For any unevenness detected, the linear drive member drives the milling mechanism to move back and forth at this place through the support frame to ensure that the surface of the clamping pliers after milling is flat.

[0050] The specific implementation is as follows: when the milling unit 333 trims the clamping clamp, the third electric push rod 36 drives the detection mechanism 37 to approach and fit the trimmed surface of the clamping clamp, so that the detection rod 373 detects the trimmed surface of the clamp, and uses the bubble level 374 to detect and ensure that the surface after milling by the milling unit 333 is flat. When the detection rod 373 detects, the friction wheel 376 is driven to rotate by adjusting the motor 375, so that the friction wheel 376 drives the detection rod 373 to move on the lifting plate 371, so that the detection rod 373 can detect the surface after milling by the milling unit 333.

[0051] In another embodiment provided by the present invention, the upper end of the detection rod 373 is a rough surface;

[0052] The specific implementation is as follows: the rough surface of the upper end of the detection rod 373 is conducive to increasing the friction between the friction wheel 376 and the upper end of the detection rod 373, ensuring that the friction wheel 376 can stably drive the detection rod 373 to move along the lifting plate 371.

[0053] In another embodiment provided by the present invention, the detection rod 373 is composed of a plurality of detection segments 3730 connected together.

The segmented detection method can ensure that the milled surface is flat in all places. At the same time, the vertical arrangement of the bubble levels 374 on the two adjacent detection sections 3730 can simultaneously detect the flatness of the surface of the fixture along the length direction of the detection rod 373 and the vertical direction of the length direction of the detection rod 373, ensuring that the surface of the clamp after trimming of the milling unit 333 is flat.

[0055] In another embodiment provided by the present invention, the detection mechanism 37 further includes a rack 377, which is arranged on a side of the detection rod 373 away from the lifting plate 371, and a protrusion 378 is provided on the side of the detection rod 373 provided with the rack 377, and a mounting block 379 is slidably provided on the protrusion 378, and a moving motor 3710 is provided in the mounting block 379, and a transmission gear 3711 is provided at the output end of the moving motor 3710, and the transmission gear 3711 is meshed with the rack 377, and a plurality of detection blocks 3712 are slidably provided at the lower end of the mounting block 379, and a return spring 3713 is provided between the detection block 3712 and the mounting block 379, and a displacement sensor 3714 is provided above the detection block 3712, and the displacement sensor 3714 is provided in the mounting block 379;

[0056] The specific implementation is as follows: when the surface milled by the milling unit 333 is inspected by multiple inspection sections 3730, the transmission gear 3711 is driven to rotate by the mobile motor 3710, so that the transmission gear 3711 rotates and engages with the racks 377 at different locations, so that the transmission gear 3711 drives the mounting block 379 to move along the inspection rod 373. When the mounting block 379 moves along the inspection rod 373, the mounting block 379 is guided and limited by the protrusion 378, so that the mounting block 379 drives the inspection block 3712 to move along the inspection rod 373, so that the inspection block 3712 detects the surfaces at different locations of the clamping clamp. When the inspection block 3712 is inspecting, When the milled surface is uneven, the detection block 3712 can squeeze the reset spring 3713 and move along the mounting block 379, so that the distance between the upper end of the detection block 3712 and the displacement sensor 3714 changes, so that the displacement sensor 3714 detects the displacement length of the detection block 3712, and by comparing the detection results of each displacement sensor 3714, the flatness of the surface milled by the clamping clamp can be obtained. For the uneven milled surface, the linear drive part 30 drives the support frame 31 to move in the opposite direction along the base 1, so that the milling unit 333 re-mills the detected uneven surface to ensure that the surface of the clamping clamp after trimming by the milling unit 333 is flat.

[0058] The first step: placing the clamping pliers, first place the clamping pliers on the movable plate 21, then rotate the adjusting screw 22, so that the adjusting screw 22 drives the two extrusion plates 23 arranged thereon to approach the clamping pliers through the opposite threads at both ends thereof, so that the extrusion plates 23 slide along the movable plate 21, so that the two extrusion plates 23 are tightly attached to the surface of the end of the clamping pliers through the flexible member 230, continue to rotate the adjusting screw 22, so that the adjusting screw 22 clamps the clamping pliers through the extrusion plates 23 and the flexible member 230, after the clamping pliers are clamped and fixed, the movable plate 21 is driven vertically by the fourth electric push rod 20, so that the movable plate 21 drives the clamped and fixed clamping pliers to move vertically, so that the movable plate 21 adjusts the position height of the clamping pliers, which facilitates the milling mechanism 33, the welding mechanism 35 and the detection mechanism 37 to perform corresponding work on the clamping pliers;

[0059] Step 2: Repair the clamping pliers. After the clamping pliers are clamped and fixed by the extrusion plate 23, the repair method is first determined according to the damage condition. First, for a structure in which the clamping pliers is flat and only has defects such as potholes, the first electric push rod 32 drives the milling unit 333 to approach the clamping pliers after clamping, and by replacing different tools, the milling unit 333 performs milling on the clamping pliers of the flat structure. At the same time, the linear drive member 30 drives the support frame 31 to move along the base 1, so that the milling unit 333 performs milling on the surface of the clamping pliers. The milling unit 333 cuts and removes the potholes on the plane of the clamping clamp; secondly, for the clamping clamp with a broken or missing planar structure, the second electric push rod 34 first drives the welding unit 351 to move close to the clamping clamp, and then the welding unit 351 welds and fills the broken or missing clamp, so that the broken or missing clamp is repaired into a whole, and after the clamp is repaired, the first electric push rod 32 drives the welding unit 351 close to the clamp after the repair is completed, so that the milling unit 333 moves the welded clamp to the clamp. The milling is performed so that the milling unit 333 can trim the clamping clamp after the welding and patching by the welding unit 351; thirdly, for a structure in which the clamping clamp is a curved surface and has only defects such as potholes on the surface, the first electric push rod 32 drives the milling unit 333 to approach the clamping clamp after clamping, and by replacing different tools, the milling unit 333 can perform milling on the clamping clamp of the curved surface structure, and when the milling unit 333 performs milling on the clamping clamp of the curved surface structure, the rotating motor 331 drives the driving gear 332 to rotate forward and reverse, The driving gear 332 drives the arc-shaped rack 334 meshing with it to rotate forward and reverse, thereby causing the arc-shaped rack 334 to drive the milling unit 333 to rotate forward and reverse around its rotation center, thereby causing the milling unit 333 to drive the milling cutter to repeatedly move in an arc trajectory around the rotation center of the milling unit 333. At the same time, the linear drive member 30 drives the support frame 31 to move along the base 1, thereby causing the milling unit 333 to mill the curved surface of the clamping clamp, so that the milling unit 333 cuts and removes potholes on the curved surface of the clamping clamp;Fourthly, for the clamping clamp with a broken or missing curved surface structure, the second electric push rod 34 is used to drive the welding unit 351 to move close to the clamping clamp, and then the welding unit 351 is used to weld and fill the broken or missing clamping clamp, so that the broken or missing clamping clamp is repaired into a whole. After the clamping clamp is repaired, the first electric push rod 32 is used to drive the welding unit 351 close to the clamping clamp after repair, so that the milling unit 333 mills the welded clamping clamp, and the rotating motor 331 is used to drive the driving gear 332 to rotate forward and reverse, so that the driving gear 332 drives the arc-shaped rack 334 meshing with it to rotate forward and reverse, thereby The arc-shaped rack 334 drives the milling unit 333 to rotate forward and backward around its rotation center, and then the milling unit 333 drives the milling cutter to repeatedly move in an arc trajectory around the rotation center of the milling unit 333. At the same time, the linear drive member 30 drives the support frame 31 to move along the base 1, so that the milling unit 333 mills the curved surface of the clamping clamp, so that the milling unit 333 can trim the clamping clamp after the welding unit 351 welds and repairs the material; and after the welding unit 351 is welded and repaired, the driving motor 352 drives the rotating wheel 353, so that the rotating wheel 353 drives the connecting rod 354 to swing, so that the The connecting rod 354 drives the inserting knife 355 to move back and forth in the second mounting plate 350, so that the inserting knife 355 can flatten the surface of the clamping clamp after welding; when the milling unit 333 trims the clamping clamp, the third electric push rod 36 drives the detection mechanism 37 to approach and fit the trimmed surface of the clamping clamp, so that the detection rod 373 detects the trimmed surface of the clamping clamp, and uses the bubble level 374 to detect and ensure that the surface milled by the milling unit 333 is flat. When the detection rod 373 detects, the friction wheel 376 is driven to rotate by adjusting the motor 375, so that the friction wheel 376 drives the detection rod 373 to move on the lifting plate 371, so that the The detection rod 373 detects the surface after milling by the milling unit 333, and the detection rod 373 performs segmented detection on the milled surface through multiple detection segments 3730, so as to keep the milled surface flat at all locations. At the same time, the transmission gear 3711 is driven to rotate by the mobile motor 3710. As the transmission gear 3711 rotates and engages with the racks 377 at different locations, the transmission gear 3711 drives the mounting block 379 to move along the detection rod 373, so that the mounting block 379 drives the detection block 3712 to move along the detection rod 373, so that the detection block 3712 detects the surfaces of the clamping clamp at different locations, thereby ensuring that the surface of the clamping clamp after trimming by the milling unit 333 is flat.

[0060] Step 3: Remove and try it out. After the clamp is repaired, rotate the adjusting screw 22 in the opposite direction so that the adjusting screw 22 drives the extrusion plate 23 away from the clamp, thereby releasing the locking fixation of the clamp by the extrusion plate 23, making it easier to remove the repaired clamp. After the repaired clamp is removed from the movable plate 21, install the repaired clamp back to the original fixture and try it out to ensure that the repaired clamp can be used normally.
