Description
Technical Field
[0001] This application relates to the technical field of stepper driver housing machining, and in particular to a machining apparatus for stepper driver fan screw holes. Background Technology
[0002] Currently, such as Figure 1 The stepper driver housing 7 shown has a fan slot on its surface, and four screw holes are required around the fan slot for fixing the fan.
[0003] In the existing technology, the clamping structure in the hole-opening equipment is relatively simple, requiring clamping and fixing from three directions: left, right and rear. The clamping process is relatively troublesome. At the same time, the hole-opening machine uses a single drill bit, resulting in low hole-opening efficiency. Utility Model Content
[0004] The purpose of this application is to provide a machining device for the screw hole of a stepper driver fan, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this application provides a processing device for the screw hole of a stepper driver fan, employing the following technical solution:
[0006] A machining device for machining screw holes in a stepper driver fan includes a worktable, a fixture for positioning the driver housing mounted on the worktable, and a drilling mechanism mounted on the worktable. The fixture includes a three-jaw chuck, a first cylinder, and a counterweight. The three-jaw chuck is rotatably mounted on the worktable. The first cylinder is fixed on the worktable. The counterweight is fixed to the piston rod end of the first cylinder. The first cylinder can drive the counterweight to move back and forth.
[0007] The drilling mechanism includes a bracket fixed on the worktable, on which two-axis moving modules are symmetrically fixed. Drilling components and tapping components are respectively installed on the two two-axis moving modules.
[0008] The two-axis motion module includes an X-axis motion module and a Z-axis motion module, with the Z-axis motion module mounted on the X-axis motion module.
[0009] Preferably, both the drilling assembly and the tapping assembly include a mounting bracket, a drive motor, a drive gear, a driven gear, and a tool holder. The drive motor is fixed on the mounting bracket, the drive gear is fixed on the output shaft of the drive motor, and the number of tool holders and driven gears is set to four. The driven gear is fixed on the tool holder, the four tool holders are evenly arranged around the drive gear, and the tool holders are rotatably connected to the mounting bracket. The driven gear meshes with the drive gear.
[0010] When the drilling and tapping assemblies are in operation, the drive motor drives the drive gear to move, and the drive gear drives the four driven gears to rotate, which in turn drives the tool holder to rotate. This allows all four tool heads to work simultaneously, greatly improving drilling and tapping efficiency.
[0011] The drilling assembly has a hole drill bit mounted on the tool holder, and the tapping assembly has a tapping drill bit mounted on the tool holder.
[0012] Preferably, the worktable surface has a through groove, a support platform is provided in the middle of the through groove, the fixture is provided on the support platform, a rotating shaft is fixed in the middle of the support platform, the rotating shaft is rotatably connected in the worktable, and a servo reduction motor is also provided on the worktable to drive the rotating shaft to rotate.
[0013] By adopting the above technical solution, after the material is picked up, the servo geared motor drives the rotating shaft to rotate one revolution, which causes the bearing platform to rotate one revolution. During this process, the waste on the surface of the bearing platform and the surface of the three-jaw chuck will fall off under their own gravity, thus making it convenient to place a new stepper driver housing.
[0014] Preferably, in order to ensure that the support platform can be in a stable state during drilling, a second cylinder and a support block are symmetrically arranged on both sides of the bottom of the worktable. The support block is slidably connected to the bottom of the worktable, and the second cylinder is fixed to the bottom of the worktable and is used to drive the support block to move.
[0015] In summary, this application includes at least one of the following beneficial technical effects:
[0016] 1. The fixture structure used in the processing equipment for the fan screw hole of the stepper driver is simple and easy to clamp. When using it, simply place the fan groove in the driver housing facing the three-jaw chuck. The three-jaw chuck works to fix the driver housing inside through the fan groove. Then, the first cylinder extends and drives the balance block to press against the side of the driver housing, which can keep the driver housing in a horizontal state and fix it.
[0017] 2. When the drilling and tapping components are in operation, the drive motor drives the drive gear to move, and the drive gear drives the four driven gears to rotate, which in turn drives the tool holder to rotate. This allows all four tool heads to work simultaneously, greatly improving drilling and tapping efficiency. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.
[0024] This application discloses a machining device for the fan screw hole of a stepper driver, referring to... Figure 2-4 The device includes a worktable 1, a fixture for positioning the driver housing on the worktable 1, and a rotating hole mechanism 3 on the worktable 1. The fixture includes a three-jaw chuck 21, a first cylinder 22, and a balance block 23. The three-jaw chuck 21 is rotatably mounted on the worktable 1. The first cylinder 22 is fixed on the worktable 1. The balance block 23 is fixed to the piston rod end of the first cylinder 22. The first cylinder 22 can drive the balance block 23 to move back and forth.
[0025] The drilling mechanism 3 includes a bracket 31 fixed on the worktable 1. Two-axis moving modules are symmetrically fixed on the bracket 31. Drilling assembly 32 and tapping assembly 33 are respectively installed on the two two-axis moving modules. The two-axis moving modules include an X-axis moving module and a Z-axis moving module. The Z-axis moving module is installed on the X-axis moving module.
[0026] Both the drilling assembly 32 and the tapping assembly 33 include a mounting bracket 321, a drive motor 322, a drive gear 323, a driven gear 324, and a tool holder 325. The drive motor 322 is fixed on the mounting bracket 321, and the drive gear 323 is fixed on the output shaft of the drive motor 322. The number of tool holders 325 and driven gears 324 is set to four. The driven gears 324 are fixed on the tool holders 325. The four tool holders 325 are evenly arranged around the drive gears 323, and the tool holders 325 are rotatably connected to the mounting bracket 321. The driven gears 324 mesh with the drive gears 323. A hole drill bit 326 is installed on the tool holder 325 in the drilling assembly 32, and a tapping drill bit 331 is installed on the tool holder 325 in the tapping assembly 33.
[0027] Reference Figure 2 The worktable 1 has a through groove on its surface, and a support platform 11 is set in the middle of the through groove. The fixture is set on the support platform 11. A rotating shaft 111 is fixed in the middle of the support platform 11. The rotating shaft 111 is rotatably connected inside the worktable 1. A servo reduction motor 4 is also set on the worktable 1. The servo reduction motor 4 is used to drive the rotating shaft 111 to rotate.
[0028] After the material is picked up, the servo geared motor 4 drives the rotating shaft 111 to rotate one revolution, causing the support platform 11 to rotate one revolution. During this process, the waste on the surface of the support platform 11 and the surface of the three-jaw chuck 21 will fall off under their own gravity, thus making it easier to place a new stepper driver housing.
[0029] Reference Figure 3 In order to provide support for the support platform 11, a second cylinder 5 and a support block 6 are symmetrically arranged on both sides of the bottom of the workbench 1. The support block 6 is slidably connected to the bottom of the workbench 1, and the second cylinder 5 is fixed to the bottom of the workbench 1 and is used to drive the support block 6 to move.
[0030] The implementation principle of the processing equipment for the fan screw hole of the stepper driver according to the embodiments of this application is as follows:
[0031] When in use, the operator places the fan slot in the driver housing facing the three-jaw chuck 21. The three-jaw chuck 21 works to fix the driver housing internally through the fan slot. Then, the first cylinder 22 extends and drives the balance block 23 to press against the side of the driver housing, thereby keeping the driver housing in a horizontal position. After fixing the driver housing, drilling and tapping are carried out in sequence.
[0032] When the drilling assembly 32 and the tapping assembly 33 are working, the drive motor 322 drives the drive gear 323 to move, and the drive gear 323 drives the four driven gears 324 to rotate, which in turn drives the tool holder 325 to rotate. This enables all four tool heads to work at the same time, greatly improving the drilling and tapping efficiency.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
