Technical Field
[0001] This invention relates to the field of generator bracket processing technology, and in particular to a drilling fixture for generator brackets. Background Technology
[0002] Generator brackets are essential structures used to support and mount generators. They are typically made of steel or other metal materials, possessing sufficient strength and stability to bear and support the weight of the generator and resist the effects of the external environment. Drilling is required in the brackets to facilitate subsequent installation processes such as fixing, connecting, or wiring.
[0003] Some generator brackets require machining holes of various diameters. Existing tooling requires disassembling many fastening screws to replace drill bushings, and the incorrect installation of drill bushings can easily lead to batch scrapping. Summary of the Invention
[0004] In order to overcome the shortcomings of existing tooling, which requires the removal of multiple fastening screws when changing drill bushings and is prone to incorrect installation, resulting in the risk of batch scrapping during multi-variety production, this invention provides a drilling tooling for generator brackets.
[0005] The technical solution of this invention is as follows: A drilling fixture for a generator bracket includes a base and guide columns. Several guide columns are provided on the top of the base. A drill sleeve seat is fixedly connected to each guide column. A pressure plate is slidably connected to each guide column, and the pressure plate is located directly above the drill sleeve seat. A connecting plate is provided at the rear end of the base, and a cylinder is connected to the connecting plate. The telescopic rod of the cylinder is connected to the top of the pressure plate. The drill sleeve seat has four through holes, each containing an installation ring. Four L-shaped grooves are provided on the installation rings. Two first guide rods are slidably connected to the top of the lower sidewall of each L-shaped groove. A movable plate is provided on the top of each first guide rod. A pressing seat is symmetrically connected to the top of the movable plate. The side of the pressing seat near the middle of the movable plate is designed as a slope.

The drill sleeve body is slidably connected inside the mounting ring. Four protrusions are provided on the outside of the drill sleeve body. The protrusions fit into the L-shaped groove. A trigger strip is provided on the top of the protrusion. Three trigger holes on one of the trigger blocks in a mounting ring have built-in trigger switches. Several indicator lights corresponding to the positions of the through holes are provided on the top of the drill sleeve seat. The three trigger switches in a mounting ring are electrically connected to the indicator lights adjacent to the mounting ring. The indicator lights contain three colors, and each trigger switch corresponds to one color of the indicator light. Several electric drill bits are provided at the bottom of the pressure plate. The electric drill bits are located directly above the through holes.
[0006] In one embodiment, the bump includes a first bump, a second bump, and a third bump, with each different diameter drill bushing body corresponding to one type of bump.
[0007] In one embodiment, the top of the drill bushing body is designed as a tapered orifice.
[0008] In one embodiment, the top of the extrusion seat is designed to fit into the bottom of the bump.
[0009] In one embodiment, the system also includes a limiting rod and a limiting block. The bottom of the drill sleeve base is provided with a limiting rod, the spacing between the limiting rods corresponds to the width of the generator bracket, and the rear top of the base is provided with a limiting block for limiting the position of the generator bracket.
[0010] In one embodiment, the system further includes a wedge block, a second guide rod, a sleeve, and a pull plate. The sleeve is located inside the front side of the base. A second compression spring is connected to the lower side wall of the sleeve. A second guide rod is connected to the top of the second compression spring. A wedge block is located at the top of the second guide rod. The distance between the rear side of the wedge block and the front side of the limiting block corresponds to the length of the generator bracket. A groove is opened on the front side of the sleeve. A pull plate is located at the front end of the second guide rod, and the pull plate passes through the groove.
[0011] In one embodiment, the system further includes a worm, a knob, a worm wheel, a bidirectional screw, a guide rod, and a fixing block. The bottom of the drill sleeve is rotatably connected to the worm via a first connector. A knob is provided at the front end of the worm.

[0012] In one embodiment, a limiting element is also included. Several rectangular slots are opened on the drill sleeve base, and the limiting element is slidably connected to the rectangular slots. The end of the limiting element near the drill sleeve body is designed as an arc-shaped block.
[0013] In one embodiment, a shock-absorbing spring is also included, with a shock-absorbing spring connected between the pressure plate and the drill sleeve seat, and the shock-absorbing spring is sleeved on the outside of the guide post.
[0014] The beneficial effects of the present invention are as follows: 1. The present invention, by setting an L-shaped groove on the mounting ring and cooperating with the protrusion, enables quick installation and removal of the drill bushing without removing any screws or fasteners, which greatly shortens the changeover time. At the same time, after the protrusion is rotated into place, the trigger bar and the trigger switch cooperate, and the indicator light lights up in the corresponding color, which reminds the operator in real time whether the drill bushing is installed correctly, and prevents batch processing errors caused by human negligence in installing the wrong drill bushing.
[0015] 2. The limiting rod of this invention restricts the left and right displacement of the generator bracket, the inclined block and the limiting block cooperate to lock the generator bracket in front and behind, and the bidirectional screw drives the fixing block to achieve rigid clamping on the left and right sides, avoiding the bracket from shaking during processing. The multi-directional positioning and coordination effect reduces the deviation of the drilling position. Attached Figure Description

Detailed Implementation
[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0028] A drilling fixture for a generator bracket, such as Figures 1-10As shown, the system includes a base 1, guide posts 2, drill sleeve seat 3, pressure plate 4, connecting plate 5, cylinder 6, electric drill bit 7, drill sleeve body 8, trigger bar 804, mounting ring 9, first guide rod 10, first compression spring 11, moving plate 12, pressing seat 13, trigger block 14, and indicator light 15. A generator bracket 29 is placed on the top of the base 1. Several guide posts 2 are provided on the top of the base 1. Drill sleeve seats 3 are fixedly connected to the guide posts 2. Pressure plates 4 are slidably connected to the guide posts 2. The pressure plates 4 are located directly above the drill sleeve seats 3. The rear end of the base 1 is equipped with... Connecting plate 5, with cylinder 6 connected to it. The telescopic rod of cylinder 6 is connected to the top of pressure plate 4. Drill sleeve seat 3 has four through holes, which are vertically aligned with the drill hole to be machined on generator bracket 29. Each through hole is equipped with mounting ring 9, which has four L-shaped grooves 901. Two first guide rods 10 are slidably connected to the top of the lower side wall of L-shaped grooves 901. The top of the first guide rod 10 is equipped with a moving plate 12. The top of the moving plate 12 is symmetrically connected with extrusion seats 13. The top of the extrusion seats 13 is designed to fit with the bottom of the protrusion to avoid... To prevent the protrusions from loosening and ensure the drill bushing body 8 is firmly fixed, the side of the compression seat 13 near the middle of the moving plate 12 is designed as a slope. A first compression spring 11 is connected between the bottom of the moving plate 12 and the lower side wall of the L-shaped groove 901. A trigger block 14 is fixedly connected to the end of the L-shaped groove 901 away from the opening. The bottom of the trigger block 14 has three trigger holes 1401. The drill bushing body 8 is slidably connected inside the mounting ring 9. Four protrusions are provided on the outside of the drill bushing body 8. The protrusions fit into the L-shaped groove 901. A trigger strip 804 is provided on the top of the protrusion. A mounting ring 9 is also provided. One of the trigger blocks 14 has three trigger holes 1401 with built-in trigger switches. The top of the drill sleeve base 3 is provided with several indicator lights 15 corresponding to the positions of the through holes. The three trigger switches in a mounting ring 9 are electrically connected to the indicator lights 15 adjacent to the mounting ring 9. The indicator lights 15 include three colors, and each trigger switch corresponds to one color of the indicator light 15. The bottom of the pressure plate 4 is provided with several electric drill bits 7. The electric drill bits 7 are located directly above the through holes. The top of the drill sleeve body 8 is designed with a tapered opening to facilitate the guidance of the electric drill bits 7.
[0029] like Figure 10 As shown, the bumps include a first bump 801, a second bump 802 and a third bump 803, and each drill bushing body 8 with a different hole diameter corresponds to a type of bump.
[0030] like Figure 1 As shown, it also includes a limiting rod 27 and a limiting block 28. The bottom of the drill sleeve base 3 is provided with a limiting rod 27, and the spacing of the limiting rods 27 corresponds to the width of the generator bracket 29. The rear side of the top of the base 1 is provided with a limiting block 28 for limiting the position of the generator bracket 29.
[0031] like Figure 7As shown, it also includes a wedge block 16, a second guide rod 17, a sleeve 18, and a pull plate 19. The sleeve 18 is provided inside the front side of the base 1. A second compression spring is connected to the lower side wall of the sleeve 18. The second guide rod 17 is connected to the top of the second compression spring. The wedge block 16 is provided at the top of the second guide rod 17. The distance between the rear side of the wedge block 16 and the front side of the limiting block 28 corresponds to the length of the generator bracket 29. A sliding groove 1801 is opened on the front side of the sleeve 18. A pull plate 19 is provided at the front end of the second guide rod 17. The pull plate 19 passes through the sliding groove 1801.
[0032] like Figure 9 As shown, it also includes a worm 21, a knob 22, a worm wheel 23, a double-acting screw 24, a guide rod 25, and a fixing block 26. The bottom of the drill sleeve 3 is rotatably connected to the worm 21 through a first connector. The front end of the worm 21 is provided with a knob 22. The bottom of the drill sleeve 3 is rotatably connected to the double-acting screw 24 through a second connector. The worm wheel 23 is fixedly connected to the outer side of the middle part of the double-acting screw 24. The left and right ends of the double-acting screw 24 are threadedly connected to the fixing blocks 26. The bottom of the drill sleeve 3 is connected to the guide rod 25 through a third connector. The guide rod 25 passes through the two fixing blocks 26.
[0033] like Figure 8 As shown, it also includes a limiting component 20. Several rectangular grooves 301 are opened on the drill sleeve base 3. The limiting component 20 is slidably connected on the rectangular grooves 301. The end of the limiting component 20 near the drill sleeve body 8 is designed as an arc block.
[0034] like Figure 1 As shown, it also includes a shock-absorbing spring 201. The shock-absorbing spring 201 is connected between the pressure plate 4 and the drill sleeve seat 3. The shock-absorbing spring 201 is sleeved on the outside of the guide post 2. The shock-absorbing spring 201 can buffer the impact and vibration when the electric drill bit 7 drills, and reduce the transmission of vibration to the drill sleeve seat 3 and the generator bracket 29.
[0035] The operator aligns the drill bushing body 8 with the inner hole of the mounting ring 9, and aligns the protrusions with the opening ends of the four L-shaped grooves 901 on the mounting ring 9. Then, the operator presses down on the drill bushing body 8. As the protrusions move downwards, they touch the compression seat 13. The compression seat 13 pushes the moving plate 12 downwards along the first guide rod 10, simultaneously compressing the first compression spring 11, until the bottom of the moving plate 12 contacts the bottom of the horizontal section of the L-shaped groove 901. The operator then rotates the drill bushing body 8 clockwise, causing the protrusions to move along the horizontal section of the L-shaped groove 901 towards the end furthest from the opening. The rotation continues until the protrusions touch the inclined surface of another compression seat 13 and move to the top of that compression seat 13 via the inclined surface. The operator then releases the drill bushing body 8, and the first compression... Spring 11 loses its downward pressure constraint and begins to release its elastic potential energy, pushing the moving plate 12 upward. The moving plate 12 drives the pressing seat 13 to move upward, cooperating with the trigger block 14 to limit the protrusion from the horizontal direction, thereby initially fixing the drill bushing body 8. Then, the limiting member 20 is moved to the bottom of the drill bushing body 8 to restrict the drill bushing body 8 from moving downward in the vertical direction. During this process, the trigger bar 804 will rotate with the protrusion to the bottom of the trigger block 14. After the drill bushing body 8 is released, when the protrusion is pressed upward against the bottom of the trigger block 14 by the first compression spring 11, the trigger bar 804 will be embedded in the trigger hole 1401 to trigger the corresponding trigger switch. After the trigger switch is triggered, the circuit is connected. When the signal light 15 illuminates in the corresponding color, it indicates to the operator whether the model of the drill sleeve body 8 is correct. The operator holds both sides of the generator bracket 29 and pushes it inward horizontally from the top front side of the base 1. When the generator bracket 29 is pushed in, the left and right sides of the generator bracket 29 always slide against the inner side of the limit rod 27 to prevent the generator bracket 29 from shifting left and right. When the bottom front end of the generator bracket 29 contacts the inclined block 16 on the front side of the base 1, the inclined block 16 will press down on the inclined block 16 due to the guiding effect of the inclined block 16. After being pressured, the inclined block 16 drives the second guide rod 17 to slide down along the sleeve 18, while compressing the second compression spring inside the sleeve 18. The generator bracket 29 continues to be pushed. The generator bracket 29 is inserted until the bottom completely passes the inclined block 16. When the rear edge of the generator bracket 29 contacts the limiting block 28, the generator bracket 29 just completely passes the inclined block 16. The second compression spring loses the pressure constraint of the generator bracket 29 and releases elastic potential energy to push the second guide rod 17 and the inclined block 16 to reset. After the inclined block 16 moves up, the rear side of the inclined block 16 is in contact with the generator bracket 29. Together with the limiting block 28, it locks the front and rear positions of the generator bracket 29. Rotating the knob 22 causes the worm gear 21 to drive the worm wheel 23 and the double screw 24 to rotate. The two fixed blocks 26 move away from each other until the fixed blocks 26 are in contact with the left and right sides of the inside of the generator bracket 29 and a certain preload is applied. Then, the knob 22 is stopped.Finally, the electric drill bit 7 and cylinder 6 are started. The electric drill bit 7 rotates, and the cylinder 6 drives the pressure plate 4 to move downward, thus moving the electric drill bit 7 downward. It drills a hole in the generator bracket 29 through the inner hole of the drill sleeve body 8. After machining, the operator pulls down the pull plate 19. The pull plate 19 drives the second guide rod 17 to move downward along the inside of the sleeve 18. The downward movement of the second guide rod 17 causes the wedge block 16 to descend synchronously, causing the rear side of the wedge block 16 to disengage from the front edge of the generator bracket 29, releasing the front and rear locking of the generator bracket 29. Then, the operator can pull the generator bracket 29 outward horizontally from the top front side of the base 1.
