Description

Technical Field

[0001] This utility model relates to the field of electric motor processing technology, and in particular to a positioning fixture for processing electric motor end caps. Background Technology

[0002] The motor end cover is an important component of the motor. It is generally manufactured by integral casting. After the motor end cover is formed, it still needs to be drilled or deburred. Therefore, it is necessary to perform positioning operations to facilitate the processing of the motor end cover.

[0003] The existing technology has the following problems: Existing motor end cover machining positioning fixtures can only perform simple positioning and clamping, and cannot adjust the position of the clamped motor end cover according to the machining requirements. This results in the need to repeatedly clamp the motor end cover during the entire machining process, which reduces the machining efficiency of the motor end cover and cannot meet the complex machining requirements of the motor end cover. The positioning fixture is not practical. To address these issues, we propose a motor end cover machining positioning fixture. Utility Model Content

[0005] The present invention solves its technical problem through the following technical solution: It includes a base, a lifting mechanism on the top of the base, a flipping mechanism on one side of the lifting mechanism, a driving mechanism on one side of the flipping mechanism, a rotating mechanism on the outer side of the flipping mechanism, and a clamping mechanism at the bottom of the rotating mechanism. The clamping mechanism includes a mounting groove located at the bottom of the rotating mechanism. A mounting seat is fixed to the inner wall of the mounting groove, and a hydraulic rod B is fixed to the inner wall of the mounting seat. A sliding seat is fixed to one end of the hydraulic rod B, and the sliding seat is slidably connected to the mounting groove. A gripper is fixed to the bottom of the sliding seat, a pressing mechanism is provided at the bottom of the mounting groove, and a limit mechanism is provided on the outer side of the mounting groove.

[0006] As a further improvement of this utility model, a mounting panel is provided on one side of the base.

[0007] As a further embodiment of this utility model: the lifting mechanism includes a support base, which is fixed to the top of the base by bolts. A mounting slide is fixed to the top of the support base, and a hydraulic rod A is fixed to the top of the mounting slide by bolts. A sliding block is fixed to the bottom of the hydraulic rod A, and the sliding block is slidably connected to the mounting slide.

[0008] As a further embodiment of this utility model: the flipping mechanism includes a mounting side plate, which is fixed to one side of the sliding block by bolts. The inner wall of the mounting side plate is rotatably connected to a mounting shaft, and a flipping bracket is fixed to the outer side of the mounting shaft.

[0009] As a further embodiment of this utility model: the driving mechanism includes a mounting housing, which is fixed to one side of the mounting side plate by bolts. A drive motor is fixed to the top of the mounting housing by bolts. A worm is provided at the output end of the drive motor. A worm wheel is provided on the outer side of the worm. A connecting shaft is fixed to the inner wall of the worm wheel. The connecting shaft is fixedly connected to the mounting shaft.

[0010] As a further embodiment of this utility model: the rotating mechanism includes a motor mounting bracket, which is fixed to one side of the flipping bracket by bolts. A geared motor is fixed to the inner wall of the motor mounting bracket, and a drive shaft is provided at the output end of the geared motor.

A fastening nut is provided on the outside of the bolt, and a pressure block is provided at the bottom of the fastening nut.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. The lifting mechanism moves the motor end cover up and down, while the flipping and driving mechanisms work together to flip the motor end cover, facilitating multi-face processing. The rotating mechanism adjusts the motor end cover horizontally, the clamping mechanism holds the motor end cover, the pressing mechanism presses the top of the motor end cover, and the limiting mechanism limits and blocks the outer side of the motor end cover. These mechanisms work together to achieve stable clamping and positioning of the motor end cover, and allow for omnidirectional adjustment of the clamped motor end cover. This facilitates omnidirectional processing of the motor end cover by external processing equipment, eliminating the need for repeated clamping and completing the processing of the motor end cover. This improves the processing efficiency of the motor end cover, adapts to the complex processing requirements of the motor end cover, and enhances the practicality of the positioning fixture. 2. The mounting shaft is driven to rotate by a drive mechanism. The mounting shaft drives the rotating mechanism and clamping mechanism to rotate through the flipping bracket, which in turn drives the motor end cover to rotate. This facilitates the processing of multiple surfaces of the motor end cover and improves the flexibility of the positioning operation. 3. With the clamping mechanism, after the motor end cover is clamped, the hydraulic rod C drives the pressure plate to move down and press against the top of the motor end cover, which can clamp the motor end cover and ensure the stability of the motor end cover after clamping.

[0019] Please see Figure 1-9This utility model provides a technical solution: It includes a base 100, a mounting panel 110 on one side of the base 100, a lifting mechanism on the top of the base 100, a flipping mechanism on one side of the lifting mechanism, a driving mechanism on one side of the flipping mechanism, a rotating mechanism on the outer side of the flipping mechanism, and a clamping mechanism at the bottom of the rotating mechanism.

A rotating mechanism adjusts the motor end cover horizontally, a clamping mechanism holds the motor end cover, a pressing mechanism presses the top of the motor end cover, and a limiting mechanism limits and blocks the outer side of the motor end cover. These mechanisms work together to achieve stable clamping and positioning of the motor end cover, and allow for omnidirectional adjustment after clamping. This facilitates omnidirectional machining of the motor end cover by external processing equipment, eliminating the need for repeated clamping and improving machining efficiency. It can adapt to complex machining requirements of motor end covers and enhances the practicality of the positioning fixture.

[0020] Specifically, the lifting mechanism includes a support base 210, which is fixed to the top of the base 100 by bolts. A mounting slide 220 is fixed to the top of the support base 210, and a hydraulic rod A230 is fixed to the top of the mounting slide 220 by bolts. A sliding block 240 is fixed to the bottom of the hydraulic rod A230, and the sliding block 240 is slidably connected to the mounting slide 220. By providing a lifting mechanism, the hydraulic rod A230 drives the sliding block 240 to move up and down, thereby driving the clamping mechanism to move up and down, which can adjust the height of the motor end cover.

[0021] Specifically, the flipping mechanism includes a mounting side plate 310, which is fixed to one side of the sliding block 240 by bolts. The inner wall of the mounting side plate 310 is rotatably connected to a mounting shaft 320, and a flipping bracket 330 is fixed to the outer side of the mounting shaft 320. By providing the flipping mechanism, the mounting shaft 320 is driven to rotate by the driving mechanism. The mounting shaft 320 drives the rotating mechanism to flip through the flipping bracket 330, thereby causing the motor end cover to flip, which facilitates the processing of multiple surfaces of the motor end cover.

[0022] Specifically, the drive mechanism includes a mounting housing 410, which is bolted to one side of a mounting side plate 310. A drive motor 420 is bolted to the top of the mounting housing 410. A worm gear 430 is provided at the output end of the drive motor 420. A worm wheel 440 is provided on the outer side of the worm gear 430. A connecting shaft 441 is fixed to the inner wall of the worm wheel 440. The connecting shaft 441 is fixedly connected to the mounting shaft 320. The drive mechanism drives the mounting shaft 320 to rotate. The mounting shaft 320 drives the rotation mechanism and the clamping mechanism to rotate through the flipping bracket 330, thereby causing the motor end cover to rotate. This facilitates the processing of multiple surfaces of the motor end cover and improves the flexibility of the positioning operation.

[0023] Specifically, the rotating mechanism includes a motor mounting bracket 510, which is fixed to one side of the flipping bracket 330 by bolts. A geared motor 520 is fixed to the inner wall of the motor mounting bracket 510. A drive shaft 521 is provided at the output end of the geared motor 520, and a drive bracket 530 is fixed to the bottom of the drive shaft 521. By providing a rotating mechanism, the geared motor 520 drives the drive shaft 521 to rotate, and the rotation of the drive shaft 521 drives the drive bracket 530 to rotate, thereby driving the rotating mechanism and the clamping mechanism to rotate, which enables horizontal rotation adjustment of the motor end cover.

[0024] Specifically, the clamping mechanism includes a mounting block 710, which is fixed to the top of the mounting groove 610 by bolts. A hydraulic rod C720 is fixed to the inner wall of the mounting block 710, and a pressure plate 730 is fixed to the bottom of the hydraulic rod C720. By setting up the clamping mechanism, after the motor end cover is clamped, the hydraulic rod C720 drives the pressure plate 730 to move down, pressing the pressure plate 730 against the top of the motor end cover, thus clamping the motor end cover and ensuring the stability of the motor end cover after clamping.

[0025] Specifically, the limiting mechanism includes a sliding bracket 810, which is slidably connected to the inner wall of the mounting groove 610. A limiting post 820 is fixed at the bottom of the sliding bracket 810, and a bolt 830 is fixed at the top of the sliding bracket 810. A fastening nut 840 is provided on the outside of the bolt 830, and a pressure block 850 is provided at the bottom of the fastening nut 840. By setting up the limiting mechanism, the limiting post 820 limits the side of the motor end cover, avoiding unnecessary rotation of the motor end cover during processing.

[0026] Working Principle: During use, the positioning fixture is controlled by the mounting panel 110. The hydraulic rod A230 drives the sliding block 240 to move up and down, which in turn moves the clamping mechanism up and down, allowing adjustment of the motor end cover height. The drive motor 420 drives the worm gear 430 to rotate, which in turn drives the worm wheel 440. The worm wheel 440 drives the mounting shaft 320 to rotate via the connecting shaft 441. The mounting shaft 320 drives the rotating mechanism and clamping mechanism to rotate via the flipping bracket 330, thus flipping the motor end cover for multi-face processing. The reduction motor 520 drives the drive shaft 521 to rotate, which in turn drives the drive bracket 530 to rotate, thus rotating the rotating mechanism and clamping mechanism, allowing for horizontal adjustment of the motor end cover. After clamping the motor end cover, the hydraulic rod C720 drives... The pressure plate 730 moves downward and rests against the top of the motor end cover, enabling the motor end cover to be clamped. Before clamping, the sliding bracket 810 is moved to a suitable position according to the size of the motor end cover, the fastening nut 840 is tightened on the bolt 830, and the pressure block 850 is pressed onto the mounting groove 610, enabling the sliding bracket 810 to be locked in place. During clamping, the side of the motor end cover is limited by the limiting post 820 to prevent unnecessary rotation of the motor end cover during processing. The sliding seat 640 is moved by the hydraulic rod B630, and the movement of the sliding seat 640 drives the jaw 650 to move, clamping the motor end cover. The above mechanisms work together to achieve stable clamping and positioning of the motor end cover, and allow for all-round adjustment of the clamped motor end cover, facilitating all-round processing of the motor end cover by external processing equipment.
