Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of equipment maintenance construction, and in particular provides a support for grinding and repairing a damaged drill bit. Background Art
[0002] During equipment maintenance and repair, damaged drill bits are generally repaired by grinding and repairing them directly on a grinding machine. The disadvantages of this method are: first, the vibration caused by the grinding machine during the grinding and repair process can easily cause the drill bit to fall off, which is time-consuming; second, the shaking of the drill bit during the grinding process can easily injure people, posing a great safety hazard. Utility Model Content
[0003] The purpose of the utility model is to provide a broken drill bit grinding and repairing support, which solves the problem of drill bit falling off, saves time, and also reduces personal injury and reduces safety hazards.
[0004] The utility model inserts a broken drill bit into a casing, passes the upper end of the drill bit between two clamping plates, then tightens the screw to fix the drill bit, and then turns the bolt so that the bolt hits the drill bit, and then uses a grinder or other small equipment to grind and trim the drill bit. Since the back plate, the clamping plate and the bolt limit the drill bit from four directions, the drill bit is more stable during the grinding process, which greatly reduces the possibility of the drill bit falling off and injuring people.
[0005] The utility model includes a base 1, a diagonal brace 2, a sleeve 3, a screw 4, a back plate 5, a connecting rod 6, a card plate 7, a bolt 8, and a nut 9, which are used in combination. The lower ends of the two diagonal braces 2 are welded to the top of the base 1, and the angle between the diagonal brace 2 and the base 1 is 60 degrees; the upper ends of the two diagonal braces 2 are welded to the side of the back plate 5; the two card plates 7 are welded to the front of the back plate 5, the card plates 7 are perpendicular to the ground, and the distance between the two card plates 7 is 20 mm; one end of the two connecting rods 6 is welded to the front of the back plate 5 vertically, and the other end is welded to the outside of the nut 9, and the distance between the two connecting rods 6 is 36 mm; the bolt 8 is screwed into the nut 9; the sleeve 3 is welded vertically to the base 1; the screw 4 is screwed into the side wall of the sleeve 3 (see Figure 1 、 Figure 2 ).
[0006] The base 1 is made of 40mm thick steel plate and has the following dimensions (length Width) 300 300mm; diagonal brace 2 is made of round steel with a diameter of 20mm and a length of 300mm; casing 3 is made of round tube with a diameter of 25mm and a length of 150mm; screw 4 is made of 8mm diameter and 30mm long; back plate 5 is made of 20mm thick steel plate and its size is (length Width) 100 100mm; connecting rod 6 is made of cross-sectional dimensions (length Width) 20 20mm square steel, 60mm long; card plate 7 is made of 8mm thick steel plate, the size is (length Width) 70 20mm; bolt 8 has a diameter of 36mm and a length of 80mm; nut 9 has a diameter of 36mm.
[0007] When in use, insert the broken drill bit 10 into the casing 3, pass the upper end of the drill bit 10 between the two clamping plates 7, then tighten the screw 4 to fix the drill bit 10, and then turn the bolt 8 to make the bolt 8 hit the drill bit 10, and then use a small device such as a grinder to grind and trim the drill bit 10. Since the back plate 5, clamping plate 7 and bolt 8 limit the drill bit 10 from four directions, the drill bit 10 is more stable during the grinding process, which greatly reduces the risk of the drill bit 10 falling off and injuring people ( Figure 3 、 Figure 4 ).
[0008] The advantages of the utility model are simple assembly, convenient operation, simplicity and practicality, solving the problem of drill bit falling off, saving time, and also reducing personal injury and lowering safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1-Figure 4 This is a specific embodiment of the present invention. The present invention will be further described below with reference to the accompanying drawings.
[0015] The utility model includes a base 1, an oblique support 2, a sleeve 3, a screw 4, a back plate 5, a connecting rod 6, a clamping plate 7, a bolt 8, and a nut 9, which are used in combination. The lower ends of the two oblique supports 2 are welded to the top of the base 1, and the angle between the oblique support 2 and the base 1 is 60°; the upper ends of the two oblique supports 2 are welded to the side of the back plate 5; the two clamping plates 7 are welded to the front of the back plate 5, the clamping plates 7 are perpendicular to the ground, and the distance between the two clamping plates 7 is 20 mm; one end of the two connecting rods 6 is welded perpendicularly to the front of the back plate 5, and the other end is welded to the outside of the nut 9, and the distance between the two connecting rods 6 is 36 mm; the bolt 8 is screwed into the nut 9; the sleeve 3 is welded perpendicularly to the base 1; and the screw 4 is screwed into the side wall of the sleeve 3.
[0016] During use, the broken drill bit 10 is inserted into the casing 3, and the upper end of the drill bit 10 passes between the two clamping plates 7. Then, the screw 4 is tightened to fix the drill bit 10, and then the bolt 8 is turned so that the bolt 8 hits the drill bit 10. Then, a small device such as a grinder is used to grind and trim the drill bit 10. Since the back plate 5, the clamping plate 7 and the bolt 8 limit the drill bit 10 from four directions, the drill bit 10 is more stable during the grinding process, which greatly reduces the possibility of the drill bit 10 falling off and injuring people.
[0017] During equipment maintenance, a repair support was used to repair broken drill bits, achieving excellent results. This repair support is used in combination with two diagonal braces welded at a 60° angle to the base; two diagonal braces welded at their upper ends to the side of the backplate; two clamps welded to the front of the backplate, perpendicular to the ground, with a spacing of 20 mm between them; two connecting rods welded at one end perpendicular to the front of the backplate and the other end to the outside of the nut, with a spacing of 36 mm between them; bolts threaded into the nuts; a sleeve welded perpendicularly to the base; and screws threaded into the side walls of the sleeve. During use, the broken drill bit is inserted into the sleeve, with the upper end of the drill bit passed between the two clamps. The screw is then tightened to secure the drill bit, and the bolt is then turned until it contacts the drill bit. The drill bit is then polished and repaired using a small device such as a grinder. Because the backplate, clamps, and bolts limit the drill bit from four directions, the drill bit is more stable during the polishing process, significantly reducing the risk of the drill bit falling off and causing injury. The trimming support is simple to assemble, easy to operate, simple and practical, solves the problem of drill bit falling off, saves time, and also reduces personal injury and reduces safety hazards.
