Description

Technical Field

[0001] This invention relates to the field of motor processing equipment technology, specifically a clamping fixture for stepper motor processing. Background Technology

[0002] A stepper motor is a type of electric motor that converts electrical pulse signals into corresponding angular or linear displacement. For each input pulse signal, the rotor rotates by one angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, a stepper motor is also called a pulse motor. Currently, most motors are fixed using clamps during the processing. According to Chinese patent disclosure, a clamping device for motor processing is disclosed, with publication number CN210757331U. However, the use of a pin, a tension spring, and a slot in this patent allows users to separate one end of the pin from the slot by operating the pin or insert it into the slot under the restoring force of the tension spring. This facilitates the installation and disassembly of the round rod, and makes it easier to change different clamps according to the shape of the workpiece, thus improving practicality. However, the workpiece clamping method in this patent requires the use of four hydraulic cylinders, which results in high fixture costs and low practicality. Therefore, we propose a clamping fixture for stepper motor machining. Summary of the Invention

[0003] The purpose of this invention is to provide a clamping fixture for stepper motor processing to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a clamping fixture for stepper motor processing, comprising a worktable, a support table, and a turntable. The top of the worktable is provided with a groove, the support table is disposed in the groove, a shock-absorbing mechanism is provided between the support table and the turntable, a motor is fixedly installed at the bottom of the inner wall of the groove, a rotating shaft is fixedly installed at the output end of the motor, the turntable is fixedly installed at the top of the rotating shaft, and a clamping mechanism is provided at the top of the support table. The clamping mechanism includes a limiting push plate one, a limiting push plate two, and a connecting rod. A limiting slide groove one and a limiting slide groove two are formed at the top of the worktable. The limiting push plate one and the limiting push plate two are slidably connected to the limiting slide groove one and the limiting slide groove two, respectively. A sleeve rod one is hinged to the front of the limiting push plate one, and a sleeve rod two is hinged to one side of the limiting push plate two. Both ends of the connecting rod are respectively inserted into the sleeve rod one and the sleeve rod two. A limiting rod one is fixedly installed on the inner wall of both the sleeve rod one and the sleeve rod two. A limiting rod groove is provided at one end, and the limiting rod is inserted into the limiting rod groove. A spring surrounds the outer wall of the limiting rod. One end of the spring is fixedly installed at one end of the connecting rod, and the other end of the spring is fixedly installed on the inner wall of the sleeve rod. A connecting plate is fixedly sleeved on the outer wall of the connecting rod. A push plate is fixedly installed at one end of the connecting plate. An L-shaped support plate is fixedly installed at the top of the support platform. A hydraulic cylinder is fixedly installed at the top of the L-shaped support plate, and the push plate is fixedly installed at the output end of the hydraulic cylinder.

[0005] According to the above technical solution, the first limiting push plate and the second limiting push plate are respectively adapted to the first limiting slide groove and the second limiting slide groove, the first limiting rod is adapted to the first limiting rod groove, and the first limiting slide groove and the second limiting slide groove are vertically arranged. By setting the first limiting slide groove and the second limiting slide groove, the first limiting push plate and the second limiting push plate can be fixed and slid on the support platform through the first limiting slide groove and the second limiting slide groove, respectively.

[0006] According to the above technical solution, clamping plates are provided on the back of the first limiting push plate and one side of the second limiting push plate. Disassembly and assembly mechanisms are provided between the two clamping plates and the first and second limiting push plates, respectively. Each disassembly and assembly mechanism includes an mounting rod and a pin. An mounting rod groove is provided on one side of the first limiting push plate. The mounting rod is fixedly installed on the outside of the clamping plate and inserted into the mounting rod groove. A second limiting rod is fixedly installed on the inner wall of the mounting rod groove. A stop plate is movably sleeved on the outer wall of the second limiting rod. A second limiting rod groove is provided at one end of the mounting rod, and the second limiting rod is inserted into the groove. In the second rod groove, the outer wall of the second limiting rod is surrounded by a second spring. One end of the second spring is fixedly installed on one side of the abutment plate, and the other end of the second spring is fixedly installed on the inner wall of the mounting rod groove. The top end of the first limiting push plate has a rod hole, and the pin moves through the rod hole to pass through the top end of the first limiting push plate. A hole pad is fixedly installed on the inner wall of the rod hole, and the hole pad is in close contact with the outer wall surface of the pin. The outer wall of the mounting rod has a pin groove, and the pin is inserted into the pin groove. By setting the hole pad, the connection tightness between the pin and the rod hole can be increased, thereby improving the stability of the pin in the rod hole.

[0007] According to the above technical solution, one end of the mounting rod contacts the other side surface of the abutment plate, and the mounting rod, the abutment plate, and the mounting rod groove are adapted to each other.

[0008] According to the above technical solution, the pin rod is adapted to the pin groove, and the hole gasket is made of wear-resistant rubber, which improves the service life of the hole gasket.

By setting the limiting blocks and the limiting block slots, the support platform can play a certain limiting role on the turntable, so that the turntable can drive the support platform to rotate more stably through the limiting blocks.

[0012] According to the above technical solution, a groove pad is fixedly installed on the inner wall of the support slide groove. The groove pad is in contact with the outer wall surface of the support slide plate. The groove pad is made of Teflon. By setting the groove pad, the friction between the support slide plate and the support slide groove can be reduced, thereby reducing wear.

[0013] According to the above technical solution, heat dissipation vents are provided through both sides of the inner wall of the groove, and heat dissipation fins are fixedly installed on the inner wall of the heat dissipation vents. There are several heat dissipation fins. By setting heat dissipation vents and heat dissipation fins, heat can be dissipated inside the groove, avoiding heat accumulation inside the groove and affecting the normal service life of the motor.

(3) The clamping fixture for stepper motor processing, through the joint action of rubber pads, limit blocks and limit block slots, can play a certain role in shock absorption of the support table, reduce the impact of vibration on the stepper motor during processing, and improve processing accuracy. (4) The clamping fixture for stepper motor processing can provide a certain support for the turntable by setting a support slide plate and a support slide groove, making the turntable more stable when rotating.

By setting the support slide plate 11 and the support groove 12, the turntable 3 can be supported to a certain extent, making the turntable 3 more stable when rotating. A groove pad 13 is fixedly installed on the inner wall of the support groove 12. The groove pad 13 is in contact with the outer wall surface of the support slide plate 11. The groove pad 13 is made of Teflon. By setting the groove pad 13, the friction between the support slide plate 11 and the support groove 12 can be reduced, thereby reducing wear.

The stepper motor to be processed is placed on the support platform 2. Then, the hydraulic cylinder 413 is activated, which pushes the push plate 412 towards the center of the support platform 2. The push plate 412 drives the connecting rod 405 towards the center of the support platform 2 via the connecting plate 411.

[0019] Based on Embodiment 1, a preferred embodiment of the stepper motor machining clamping fixture provided by the present invention is, for example... Figures 1 to 7As shown: Clamping plates 7 are provided on the back of limiting push plate 1 401 and one side of limiting push plate 2 403. Disassembly and assembly mechanisms 5 are provided between the two clamping plates 7 and limiting push plate 1 401 and limiting push plate 2 403 respectively. Each disassembly and assembly mechanism 5 includes an installation rod 501 and a pin 507. An installation rod groove 502 is provided on one side of limiting push plate 1 401. The installation rod 501 is fixedly installed on the outside of clamping plate 7 and inserted into the installation rod groove 502. A limiting rod 2 503 is fixedly installed on the inner wall of the installation rod groove 502. A stop plate 505 is movably sleeved on the outer wall of the limiting rod 2 503. A limiting rod groove 2 506 is provided at one end of the installation rod 501, and the limiting rod 2 503 is inserted into the limiting rod groove 2 506. A spring 2 504 surrounds the outer wall of the limiting rod 2 503. One end of the spring 2 504 is fixedly installed on one side of the stop plate 505. One end of the installation rod 501... The mounting rod 501 and the mounting rod 505 are in contact with the other side surface of the abutment plate 505. The mounting rod 501 and the abutment plate 505 are adapted to the mounting rod groove 502. The other end of the spring 504 is fixedly installed on the inner wall of the mounting rod groove 502. The top of the limiting push plate 401 has a rod hole 509. The pin 507 passes through the rod hole 509 and moves through the top of the limiting push plate 401. A hole pad 510 is fixedly installed on the inner wall of the rod hole 509. The hole pad 510 is in close contact with the outer wall surface of the pin 507. The outer wall of the mounting rod 501 has a pin groove 508. The pin 507 is inserted into the pin groove 508. The pin 507 is adapted to the pin groove 508. The hole pad 510 is made of wear-resistant rubber to improve the service life of the hole pad 510. By setting the hole pad 510, the connection tightness between the pin 507 and the rod hole 509 can be increased, thereby improving the stability of the pin 507 in the rod hole 509. Pulling pin 507 upwards causes it to disengage from pin groove 508. When pin 507 disengages from pin groove 508, it no longer limits the mounting rod 501. At this time, the abutment plate 505 will be pushed by the restoring force of spring 2 504 to move the mounting rod 501 out of mounting rod groove 502, eventually causing the mounting rod 501 to automatically disengage from mounting rod groove 502, thus completing the disassembly of clamp 7. This improves the disassembly efficiency of personnel and greatly reduces the time required for personnel to disassemble clamp 7, thereby improving the working efficiency of the fixture. The structure is simple and highly practical. Example 3

[0020] Based on Embodiment 1, a preferred embodiment of the stepper motor machining clamping fixture provided by the present invention is, for example... Figures 1 to 7As shown: The shock absorption mechanism 6 includes a limiting block 601 and a rubber pad 603. The limiting block 601 is fixedly installed at the bottom of the support platform 2. A limiting block groove 602 is opened at the top of the turntable 3. The limiting block 601 is inserted into the limiting block groove 602. The rubber pad 603 is fixedly installed between the support platform 2 and the turntable 3. There are two limiting blocks 601 and two limiting block grooves 602. The limiting blocks 601 and the limiting block grooves 602 are compatible. By setting the limiting blocks 601 and the limiting block grooves 602, the support platform 2 can play a certain limiting role on the turntable 3, so that the turntable 3 can drive the support platform 2 to rotate more stably through the limiting blocks 601. With the combined action of rubber pad 603, limit block 601 and limit block groove 602, the support platform 2 can play a certain role in shock absorption, reducing the impact of vibration on the stepper motor during processing and improving processing accuracy.
