Description

Technical Field

[0001] This utility model relates to the field of power fittings technology, specifically to a machining fixture for drilling holes in a right-angle mounting plate. Background Technology

[0002] Long-distance overhead transmission lines require the erection of transmission towers. To ensure sufficient insulation and mechanical strength, these towers are connected by insulator strings. A large number of connecting hardware, such as right-angle brackets, are needed in these insulator strings.

[0003] In the actual production process of right-angle brackets, the drilling positioning points need to be manually drawn before drilling, which consumes a lot of time. Furthermore, the position of the hole is prone to deviation during drilling, which seriously affects the connection strength and installation efficiency of the insulator string.

[0004] The authorized patent application with application number 201820257689.X includes a bracket, a processing platform, and a U-shaped positioning baffle; the processing platform is fixedly mounted on two brackets, the thickness of the processing platform is less than the gap between the right-angle hanging plates, and a drill bit clearance through hole is provided on the processing platform; the U-shaped positioning baffle is fixedly mounted on the outside of the drill bit clearance through hole on the processing platform.

[0005] The aforementioned comparison documents have the following problems:

[0006] When the right-angle bracket is installed, the machining fixture used for drilling the right-angle bracket does not have a structure to position the right-angle bracket. Relying solely on soft pads cannot reliably position the right-angle bracket, causing it to wobble easily during drilling and affecting the drilling effect.

[0007] Therefore, we have made improvements and proposed a machining fixture for drilling holes in right-angle pegboards. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] This utility model discloses a machining fixture for drilling right-angle hanging plates, including a machining platform. The machining platform is symmetrically fixedly installed with brackets at its left and right ends, and positioning bolts are installed at the bottom of the brackets. A drill bit clearance through hole is opened in the middle of the upper surface of the machining platform, and a U-shaped positioning baffle is fixedly installed on the upper surface of the machining platform at the side end of the drill bit clearance through hole. The front end of the U-shaped positioning baffle is open.

[0010] Two brackets are fixedly mounted with L-shaped mounting plates on their upper surfaces. A vertical screw rod is threaded through the L-shaped mounting plate. A first torsion handle is fixedly mounted on the upper end of the vertical screw rod, and a positioning plate is rotatably mounted on the lower end of the vertical screw rod.

[0011] As a preferred embodiment of this utility model, a rubber pad is fixedly provided on the lower end face of the processing platform.

[0012] As a preferred embodiment of this utility model, a first locking nut is threaded onto the vertical screw and located above the L-shaped mounting plate.

[0013] As a preferred technical solution of this utility model, the front end of the processing platform is symmetrically provided with two drive slots arranged in parallel along the horizontal direction. The top ends of the two supports (1) are threaded with horizontally arranged screws. The two horizontal screws are close to each other and pass through the left and right ends of the processing platform respectively, and are rotatably connected to the two drive slots close to each other on the wall.

[0014] A rectangular nut block is threaded onto the horizontal screw and located inside the drive groove. The front end of the rectangular nut block passes through the drive groove and is fixedly connected to a positioning clamp.

[0015] As a preferred technical solution of this utility model, the side end face of the rectangular nut block slides and fits against the inner wall of the drive groove in the horizontal direction.

[0016] As a preferred technical solution of this utility model, each of the two horizontal screws is fixedly installed with a second torsion handle at one end away from each other, and a second locking nut is threaded onto the horizontal screw, the second locking nut being in contact with the side end face of the bracket.

[0017] The beneficial effects of this utility model are:

[0018] 1. This type of machining fixture for drilling right-angle pegboards has a machining platform thickness smaller than the gap between the two plates of the right-angle pegboard. In practical applications, the diameter and position of the drill bit clearance hole are determined according to the drilling requirements of the right-angle pegboard. The position of the U-shaped positioning baffle is determined according to the outer edge of the right-angle pegboard. The machining fixture for drilling right-angle pegboards is fixed to a suitable position on the drilling machine with positioning bolts. The right-angle pegboard to be drilled is inserted into the U-shaped positioning baffle of the machining platform. The drill bit of the drilling machine can then press down to directly drill the right-angle pegboard.

[0019] 2. The machining fixture for drilling holes in this right-angle hanging plate: After the right-angle hanging plate is installed on this utility model, the horizontal screw can be turned by the second torsion handle. The rotation of the horizontal screw can drive the rectangular nut block, which in turn can drive the positioning clamping block. The two moving positioning clamping blocks can clamp and fix the right-angle hanging plate, thereby achieving the initial positioning of the right-angle hanging plate. After the initial positioning is completed, tightening the second locking nut can complete the locking of the horizontal screw.

[0020] 3. The machining fixture for drilling holes in this type of right-angle hanging plate can drive the vertical screw to rotate through the first torsion handle. The rotating vertical screw can drive the positioning plate to move down. The moving positioning plate can press the right-angle hanging plate tightly onto the upper part of the machining platform, thereby realizing the secondary positioning of the right-angle hanging plate. After the secondary positioning is completed, tightening the first locking nut can lock the vertical screw.

[0021] This invention enables stable positioning of right-angle mounting plates that require drilling, thereby improving drilling accuracy and increasing product production efficiency. Attached Figure Description

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1-2 As shown, the present invention provides a machining fixture for drilling right-angle hanging plates, including a machining platform 2. Supports 1 are symmetrically fixedly installed at the left and right ends of the machining platform 2, and positioning bolts 9 are installed at the bottom of the support 1. A drill bit clearance through hole 4 is opened at the middle of the upper end face of the machining platform 2, and a U-shaped positioning baffle 3 is fixedly installed on the upper end face of the machining platform 2 at the side end of the drill bit clearance through hole 4. The front end of the U-shaped positioning baffle 3 is open.

[0029] Two brackets 1 are fixedly mounted with L-shaped mounting plates 7 on their upper surfaces. A vertical screw 6 is threaded through the L-shaped mounting plate 7. A first torsion handle is fixedly mounted on the upper end of the vertical screw 6. A positioning plate 10 is rotatably mounted on the lower end of the vertical screw 6. A first locking nut 8 is threaded onto the vertical screw 6 and located above the L-shaped mounting plate 7.

[0030] The first torsion handle can drive the vertical screw 6 to rotate. The rotating vertical screw 6 can drive the positioning plate 10 to move down. The moving positioning plate 10 can press the right-angle hanging plate against the upper end of the processing platform 2, thereby realizing the secondary positioning of the right-angle hanging plate. After the secondary positioning is completed, tighten the first locking nut 8 to lock the vertical screw 6.

[0031] In this embodiment, a rubber pad 5 is fixedly provided on the lower end face of the processing platform 2, and the rubber pad 5 can make the upper end face of the right-angle hanging plate fit tightly against the processing platform 2.

[0032] like Figure 1-3 As shown, the front end of the processing platform 2 has two drive slots 13 arranged in parallel along the horizontal direction. The top of each of the two supports (1) is threaded with a horizontally arranged horizontal screw 12. The two horizontal screws 12 are close to each other and pass through the left and right ends of the processing platform 2 respectively, and are rotatably connected to the two drive slots 13 close to each other. A rectangular nut block is threaded on the horizontal screw 12 and located inside the drive slot 13. The front end of the rectangular nut block passes through the drive slot 13 and is fixedly connected to a positioning clamp 11. The side end face of the rectangular nut block slides and fits against the inner wall of the drive slot 13 in the horizontal direction. The two horizontal screws 12 are fixedly installed with a second torsion handle at the ends away from each other. A second locking nut 14 is threaded on the horizontal screw 12 and fits against the side end face of the support 1.

[0033] After the right-angle hanging plate is installed on this utility model, the horizontal screw 12 can be turned by the second torsion handle. The rotation of the horizontal screw 12 can drive the rectangular nut block, which in turn can drive the positioning clamp 11. The two moving positioning clamps 11 can clamp and fix the right-angle hanging plate, thereby achieving the initial positioning of the right-angle hanging plate. After the initial positioning is completed, tightening the second locking nut 14 can lock the horizontal screw 12.

[0034] During operation, the thickness of the processing platform 2 is less than the gap between the two plates of the right-angle bracket. In practical applications, the diameter and position of the drill bit clearance through hole 4 are determined according to the drilling requirements of the right-angle bracket. The position of the U-shaped positioning baffle 3 is determined according to the outer edge of the right-angle bracket. The drilling tool for the right-angle bracket is fixed in a suitable position on the drilling machine by the positioning bolt 9. The right-angle bracket to be drilled is inserted into the U-shaped positioning baffle 3 of the processing platform 2. The drill bit of the drilling machine can then press down to directly drill the right-angle bracket.

[0035] The inner edge of the U-shaped positioning baffle 3 matches the outer edge of the right-angle hanging plate.

[0036] After the right-angle hanging plate is installed on this utility model, the horizontal screw 12 can be turned by the second torsion handle. The rotation of the horizontal screw 12 can drive the rectangular nut block, which in turn can drive the positioning clamp 11. The two moving positioning clamps 11 can clamp and fix the right-angle hanging plate, thereby achieving the initial positioning of the right-angle hanging plate. After the initial positioning is completed, tightening the second locking nut 14 can lock the horizontal screw 12.

[0037] The first torsion handle can drive the vertical screw 6 to rotate. The rotating vertical screw 6 can drive the positioning plate 10 to move down. The moving positioning plate 10 can press the right-angle hanging plate against the upper end of the processing platform 2, thereby realizing the secondary positioning of the right-angle hanging plate. After the secondary positioning is completed, tighten the first locking nut 8 to lock the vertical screw 6.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
