For workpieces of different shapes and sizes, there are different positioning and clamping requirements. However, the existing repair tooling cannot meet the positioning and clamping requirements of workpieces of various shapes and sizes at the same time.

[0003] Therefore, in order to address the above problems, this utility model urgently needs to provide a clamping and repair fixture suitable for sheet metal workpieces. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping and repair fixture suitable for sheet metal workpieces. The structure design of multiple pin holes arranged in a matrix solves the problem that existing repair fixtures cannot simultaneously meet the positioning and clamping requirements of sheet metal workpieces with different shapes.

[0005] A clamping and repair fixture suitable for sheet metal workpieces includes a base plate, on the upper surface of which a plurality of pin holes are spaced apart, and a plurality of pins that match the pin holes.

[0006] A pressure plate is provided at intervals above the base plate. The pressure plate is movably connected to the base plate through a height adjustment mechanism. A workpiece clamping gap is provided between the base plate and the pressure plate.

[0007] One end of the base plate extends downward to form a side plate. Clamping plates are spaced apart on the outer side of the side plate. The middle section of the clamping plate is movably connected to the side plate by a first bolt. The distance between the outer side of the clamping plate and the side plate is adjustable. A cutting machine clamping gap is provided between the inner side of the clamping plate and the side plate.

[0008] Furthermore, the outer surface of the side plate has two second screw holes and two first screw holes for connecting the first bolts, which are opened from the outside to the inside along the horizontal plane.

[0009] Furthermore, a second bolt is screwed into the second screw hole onto one side of the clamping plate. One end of the second bolt is in contact with the inner side of the clamping plate and is used to adjust the distance between the outer side of the clamping plate and the side plate.

[0010] Furthermore, each pin is a threaded pin, and each pin hole is a threaded hole that matches the threaded pin.

[0011] Furthermore, the height adjustment mechanism includes a third bolt screwed into the pin hole, the head of which is pressed against the upper surface of the pressure plate.

[0012] Furthermore, the pin holes are arranged in an array at equal intervals on the upper surface of the base plate.

[0013] Furthermore, the clamping plate is provided with a through hole with a diameter slightly larger than that of the first bolt, for the first bolt to pass through.

[0014] Furthermore, the pressure plate is in the shape of a disc with a diameter of 30-100mm.

[0015] Furthermore, the length of the first bolt is 50-120mm.

[0016] Furthermore, the first bolt is M16, the second bolt is M16, and the third bolt is M16.

[0017] The clamping and repair fixture for sheet metal workpieces provided by this utility model has the following advantages compared with the prior art:

[0018] This utility model provides a clamping and modification fixture for sheet metal workpieces. Depending on the application scenario, pins can be freely installed in each pin to position sheet metal workpieces of varying shapes and sizes, and a pressure plate is used for clamping and fixing.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a clamping and modification fixture suitable for sheet metal workpieces, including a base plate 1, a plurality of pin holes 2 spaced apart on the upper surface of the base plate 1, and a plurality of pins 3 that match the pin holes 2.

[0029] A pressure plate 4 is provided at intervals above the base plate 1. The pressure plate 4 is movably connected to the base plate 1 through a height adjustment mechanism. A workpiece clamping gap is provided between the base plate 1 and the pressure plate 4.

[0030] A side plate 5 extends downward from one end of the base plate 1. A clamping plate 6 is provided at intervals on the outer side of the side plate 5. The middle section of the clamping plate 6 is movably connected to the side plate 5 by a first bolt 7. The distance between the outer side of the clamping plate 6 and the side plate 5 is adjustable. A cutting machine clamping gap is provided between the inner side of the clamping plate 6 and the side plate 5.

[0031] This utility model provides a clamping and modification fixture for sheet metal workpieces. Depending on the application scenario, pins 3 can be freely installed in each pin hole 2 to position sheet metal workpieces of different shapes and sizes, and clamped and fixed using pressure plate 4. The side plate 5 and clamping plate 6 can be used to clamp the sharp grid at the bottom of the laser cutting machine, facilitating the modification of sheet metal workpieces. At the same time, by applying pressure to the center of pressure plate 4 through the third bolt 9, the sheet metal workpiece can be clamped or released according to the lever principle, and the distance between pressure plate 4 and base plate 1 can be adjusted according to the thickness of the sheet metal workpiece. By fixing the side plate 5 and clamping plate 6 together, and then using the second bolt 8 to push the outer side of clamping plate 6, the inner side of side plate 5 and clamping plate 6 can be used to clamp or release the sharp grid of the laser cutting machine according to the lever principle. It can be applied to different models of laser cutting machines.

[0032] In this embodiment, the outer surface of the side plate 5 is provided with two second screw holes 11 and two first screw holes 10 for connecting the first bolt 7 from the outside to the inside along the horizontal plane.

[0033] like Figure 1 , Figure 2 As shown, a second bolt 8 is screwed into the second screw hole 11 and onto one side of the clamping plate 6. One end of the second bolt 8 is in contact with the inner side of the clamping plate 6 and is used to adjust the distance between the outer side of the clamping plate 6 and the side plate 5.

[0034] In this utility model, after adjusting the distance between the middle section of the clamping plate 6 and the side plate 5 by adjusting the first bolt 7, tightening the second bolt 8 can push the outer side of the clamping plate 6 outward. At this time, the sharp grid of the laser cutting machine is placed in the clamping gap of the cutting machine, and tightening the second bolt 8 can clamp the cutting machine.

[0035] In this embodiment, each pin 3 is a threaded pin, and each pin hole 2 is a threaded hole that matches the threaded pin.

[0036] like Figure 1 , Figure 2 As shown, the height adjustment mechanism includes a third bolt 9 that is screwed into the pin hole 2, and the head of the third bolt 9 is pressed against the upper surface of the pressure plate 4.

[0037] In this utility model, after the stud of the third bolt 9 passes through the pressure plate 4, it is screwed into the pin hole 2, and the head is pressed on the pressure plate 4, so the height of the pressure plate 4 can be adjusted. The distance between the pressure plate 4 and the base plate 1 is used to clamp the workpiece. Therefore, tightening the third bolt 9 can achieve the clamping of the workpiece.

[0038] like Figure 1 , Figure 2 As shown, each pin hole 2 is arranged in an array at equal intervals on the upper surface of the base plate 1.

[0039] In this embodiment, the clamping plate 6 is provided with a through hole with a diameter slightly larger than the large diameter of the first bolt 7 for the first bolt 7 to pass through.

[0040] In this invention, when the second bolt 8 is tightened and pushed outward to the outside of the clamping plate 6, a certain degree of torsion will occur between the through hole on the clamping plate 6 and the first bolt 7. Therefore, there needs to be a certain gap between the through hole of the clamping plate 6 and the major diameter of the first bolt 7. If the diameter of the through hole of the clamping plate 6 is much larger than the major diameter of the first bolt 7, the clamping plate 6 may fall off the first bolt 7 during the torsion process, causing the clamping to fail.

[0041] In this embodiment, the pressure plate 4 is a disc with a diameter of 30-100mm.

[0042] In this embodiment, the length of the first bolt 7 is 50-120mm.

[0043] In this embodiment, the first bolt 7 is M16, the second bolt 8 is M16, and the third bolt 9 is M16.

[0044] The embodiments of this utility model include the following steps:

[0045] 1) Based on the different sizes and shapes of the sheet metal workpieces, multiple pins 3 are used and installed in the corresponding pin holes 2 to position the sheet metal workpieces around them.

[0046] 2) Use the third bolt 9 to install in the pin hole 2 at a specific position, fix the pressure plate 4 above the base plate 1, adjust the third bolt 9, and use the bottom surface of the pressure plate 4 and the top surface of the base plate 1 to clamp the sheet metal workpiece.

[0047] 3) Place the clamping plate 6 on the outside of the side plate 5, and use the first bolt 7 to install the clamping plate 6 into the first screw hole 10 of the side plate 5; insert the second bolt 8 through the inside of the side plate 5 into the second screw hole 11, and abut the tail of the second bolt 8 against the inside of the clamping plate 6.

[0048] 4) Place the sharp grid of the laser cutting machine between the inner side of the clamping plate 6 and the side plate 5, tighten the second bolt 8, and push the outer side of the clamping plate 6. According to the lever principle, the gap between the inner side of the clamping plate 6 and the side plate 5 becomes smaller. At this time, the sharp grid of the laser cutting machine can be clamped by using the inner side of the clamping plate 6 and the outer side of the side plate 5.

[0049] 5) Use a laser cutting machine to modify the sheet metal workpiece. After the modification is completed, unscrew the third bolt 9 to remove the modified sheet metal workpiece, thus completing the modification operation of the sheet metal workpiece.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
