Description

A base leveling device Technical Field

[0001] This application relates to the technical field of motor base grinding equipment, and in particular to a base leveling device. Background Technology

[0002] As an important component of the motor, the machining precision of the motor base affects the fit between it and the assembled components, which in turn affects the overall performance of the motor.

[0003] In existing technologies, the grinding of the end cap machining surface during motor base processing mainly relies on manual operation. Workers use grinding machines to grind the machined surfaces of the motor base. This method can meet basic grinding requirements to a certain extent, but the operation process is quite cumbersome. Specifically, workers need to manually control the speed and direction of the grinding machine and constantly monitor the grinding process to ensure the desired effect is achieved. Moreover, differences in operating techniques and experience among different workers make it difficult to maintain consistent grinding results. For motor bases with complex shapes or large sizes, the difficulty of manual grinding increases further. Due to the instability of manual operation, it is difficult to guarantee a high standard of flatness, thus affecting the processing quality and subsequent performance of the motor base. Summary of the Invention

[0004] In order to improve the grinding quality and efficiency of motor bases, this application provides a base leveling device.

[0005] This application provides a base leveling device, which adopts the following technical solution:

[0006] A base leveling device includes a base, a moving mechanism, a positioning mechanism, and a rotating grinding wheel. The positioning mechanism includes a base with a limiting flange, a lateral gripper assembly, and a pressure member. A workpiece is fitted onto the limiting flange of the base. The pressure member is located on the top of the workpiece and is used to lock the workpiece to the top surface of the base. The lateral gripper assembly is located on the base and is used to limit the side wall of the workpiece. The moving mechanism is located on the base and is assembled with the bottom of the positioning mechanism. The moving mechanism moves in a direction close to or away from the rotating grinding wheel. The rotating grinding wheel is installed on one side of the base and is used to grind the end face of the workpiece.

[0007] By adopting the above technical solution, the workpiece is fitted and inserted on the limiting flange of the base. Through the combination of the limiting flange, the lateral gripper assembly and the pressure component, the positioning mechanism can achieve multi-directional fixation of the workpiece. The three work together to greatly improve the stability of the workpiece during the grinding process. In this application, the moving mechanism drives the positioning mechanism and the workpiece to move together in the direction of approaching or moving away from the rotating grinding wheel, ensuring that the workpiece can be accurately moved to the rotating grinding wheel for grinding according to the preset trajectory, which effectively improves the automation level and work efficiency of the equipment, and improves the processing accuracy and consistency of the workpiece.

[0008] Preferably, the base includes a guide post, the limiting flange is an eccentric circular structure, and the guide post is fixed to the top of the limiting flange.

[0009] By adopting the above technical solution and setting guide posts on the base, not only is the structural strength of the base enhanced, but the placement and removal of workpieces are also facilitated. The guide posts are fixed on the top of the limiting flange of the eccentric circular structure, which helps to guide the workpiece to be placed correctly and ensures the stability of the workpiece during the grinding process.

[0010] Preferably, the lateral gripper assembly includes at least two L-shaped gripping arms, which are rotatably connected to the base, and a plurality of the L-shaped gripping arms are evenly distributed.

[0011] By adopting the above technical solution, at least two L-shaped clamping arms are rotatably connected to the base, achieving more flexible and tighter positioning of the workpiece sidewalls. The evenly distributed L-shaped clamping arms allow for adjustment according to workpieces of different sizes, contributing to improved equipment versatility and applicability.

[0012] Preferably, the end of the L-shaped clamping arm is provided with a stepped positioning step, and the vertical surface of the positioning step forms a line contact with the outer circumferential surface of the workpiece.

[0013] By adopting the above technical solution, a stepped positioning step is set at the end of the L-shaped clamping arm, and its vertical surface forms a line contact with the outer circumferential surface of the workpiece. This design improves the accuracy and stability of workpiece positioning.

[0014] Preferably, the inner wall of the positioning step is provided with anti-slip protrusions.

[0015] By adopting the above technical solution, anti-slip protrusions are set on the inner wall of the positioning step. The anti-slip protrusions can increase the friction with the workpiece surface, which helps to further enhance the stability and anti-slip effect when clamping the workpiece, thereby reducing the workpiece from sliding or shifting due to vibration or external force during the grinding process, thus improving the processing accuracy and safety.

[0016] Preferably, the end of the L-shaped clamping arm away from the anti-slip protrusion is provided with a rotating shaft, and a torsion spring is sleeved on the outer wall of the rotating shaft. One end of the torsion spring is assembled with the L-shaped clamping arm, and the other end is assembled with the moving mechanism.

[0017] By adopting the above technical solution, the L-shaped clamping arm has a certain elasticity and self-resetting ability under the combined action of the rotating shaft and the torsion spring, so that the workpiece can be clamped by the clamping arm, thereby improving the installation stability of the workpiece.

[0018] Preferably, the pressure component includes a pneumatic cylinder, a pressure transmission plate, and an elastic compensation layer. The bottom surface of the pressure transmission plate is provided with a wavy toothed surface, and the elastic compensation layer is fixed to the bottom of the pressure transmission plate by a detachable snap fastener.

[0019] By adopting the above technical solution, the pneumatic cylinder provides a stable pressure source, the pressure transmission plate distributes the pressure evenly to the workpiece surface, and the elastic compensation layer can compensate for the pressure difference caused by unevenness or slight deformation of the workpiece surface, ensuring that the workpiece always maintains a stable and uniform stress state during the grinding process. In addition, the setting of the wavy toothed surface enhances the friction between the pressure transmission plate and the workpiece, improving the installation stability of the workpiece. The pressure component in this application can apply uniform and adjustable pressure to the workpiece as needed.

[0020] Preferably, the moving mechanism includes a linear guide rail, a slider, and a driving component. The base is fixed to the top surface of the slider, the slider is slidably connected to the linear guide rail, the extension direction of the linear guide rail is consistent with the movement direction of the workpiece, and the output end of the driving component is assembled with the slider to drive the slider to move.

[0021] By adopting the above technical solution, the driving component acts as a power source, driving the slider to move along the linear guide rail. This allows the base to move smoothly and precisely on the pedestal, ensuring that the workpiece can be accurately moved to the rotating grinding wheel along a preset trajectory for grinding. This helps improve the automation level and work efficiency of the equipment, and greatly enhances processing accuracy and consistency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The workpiece is inserted into the limiting flange of the base. Through the combination of the limiting flange, the side gripper assembly and the pressure component, the positioning mechanism can fix the workpiece in multiple directions. The three work together to greatly improve the stability of the workpiece during the grinding process. In this application, the moving mechanism drives the positioning mechanism and the workpiece to move together in the direction of approaching or moving away from the rotating grinding wheel, ensuring that the workpiece can be accurately moved to the rotating grinding wheel for grinding according to the preset trajectory, which effectively improves the automation level and work efficiency of the equipment, and improves the processing accuracy and consistency of the workpiece.

[0024] 2. Setting guide posts on the base not only enhances the structural strength of the base, but also facilitates the placement and removal of workpieces. The guide posts are fixed to the top of the limiting flange of the eccentric circular structure, which helps to guide the workpiece to be placed correctly and ensures the stability of the workpiece during the grinding process.

[0025] 3. The pneumatic cylinder provides a stable pressure source, the pressure transmission plate distributes the pressure evenly to the workpiece surface, and the elastic compensation layer can compensate for the pressure differences caused by unevenness or slight deformation of the workpiece surface, ensuring that the workpiece always maintains a stable and uniform stress state during the grinding process. In addition, the wavy toothed surface setting enhances the friction between the pressure transmission plate and the workpiece, improving the installation stability of the workpiece.

[0029] The present application will be further described in detail below with reference to Figures 1-2.

[0030] This application discloses a base leveling device.

[0031] Referring to Figure 1, a base leveling device includes a base 1, a moving mechanism 2, a positioning mechanism 3, and a rotating grinding wheel 4. The positioning mechanism 3 includes a base 31 with a limiting flange 32, a lateral gripper assembly 34, and a pressure member 35. The workpiece 5 is fitted and inserted into the limiting flange 32 of the base 31. The pressure member 35 is disposed on the top of the workpiece 5 and is used to lock the workpiece 5 to the top surface of the base 31. The lateral gripper assembly 34 is disposed on the base 31 and is used to limit the side wall of the workpiece 5. Through the combination of the limiting flange 32, the lateral gripper assembly 34, and the pressure member 35, the positioning mechanism 3 can achieve multi-directional fixation of the workpiece 5.

[0032] Furthermore, the moving mechanism 2 is mounted on the base 1 and assembled with the bottom of the positioning mechanism 3. The moving mechanism 2 moves along the direction of approaching or moving away from the rotating grinding wheel 4. The rotating grinding wheel 4 is mounted on one side of the base 1 and is used to grind the end face of the workpiece 5. In this application, the moving mechanism 2 drives the positioning mechanism 3 and the workpiece 5 to move together in the direction of approaching or moving away from the rotating grinding wheel 4, ensuring that the workpiece 5 can accurately move to the rotating grinding wheel 4 according to the preset trajectory for grinding, effectively improving the automation level and working efficiency of the equipment, and improving the processing accuracy and consistency of the workpiece 5.

[0033] Specifically, referring to Figures 1 and 2, the moving mechanism 2 includes a linear guide rail 21, a slider 22, and a driving component 23. The base 31 is fixed on the top surface of the slider 22. The slider 22 is slidably connected to the linear guide rail 21. The extension direction of the linear guide rail 21 is consistent with the movement direction of the workpiece 5. The output end of the driving component 23 is assembled with the slider 22 and is used to drive the slider 22 to make displacement. In this application, the specific structure of the driving component 23 is not limited. As a power source, the driving component 23 can drive the slider 22 to move along the linear guide rail 21. For example, the driving component 23 in the prior art can be selected. The driving component 23 includes a motor and a screw, with the motor fixed at one end of the base 1 and the screw fixed in the extension direction of the base 1, so that the screw is parallel to the slide rail. The slider 22 is threadedly connected to the screw and simultaneously slides with the linear guide rail 21. When the motor 42 is started, the screw can rotate, and the slider 22 can move along the linear guide rail 21, thereby making the base 31 move smoothly and accurately on the base 1, ensuring that the workpiece 5 can be accurately moved to the rotating grinding wheel 4 for grinding according to the preset trajectory.

[0034] Referring to Figures 1 and 2, in this application, the limiting flange 32 of the base 31 has several layers. The limiting flange 32 has an eccentric circular structure. From the bottom of the base 31 upwards, the radial dimension of the limiting flange 32 gradually decreases. The base 31 includes a guide post 33, which is fixed to the top of the limiting flange 32. When the operator inserts the workpiece 5 into the guide post 33, it helps to guide the workpiece 5 to be placed correctly and also provides convenience for the placement and removal of the workpiece 5. Simultaneously, the slot of the workpiece 5 is inserted into the limiting flange 32 that is compatible with it, thereby achieving the initial fixation of the workpiece 5.

[0035] Furthermore, the lateral gripper assembly 34 includes at least two L-shaped gripping arms 341, and several L-shaped gripping arms 341 are evenly distributed. In the accompanying drawings of this application, two L-shaped gripping arms 341 are shown, which are arranged symmetrically. The L-shaped gripping arms 341 are rotatably connected to the base 31. Specifically, one end of the L-shaped gripping arm 341 is provided with a rotating shaft 342, and the outer wall of the rotating shaft 342 is fitted with a torsion spring 343. One end of the torsion spring 343 is assembled with the L-shaped gripping arm 341, and the other end is assembled with the moving mechanism 2. The other end of the L-shaped gripping arm 341 is provided with a stepped positioning step 3411. The vertical surface of the positioning step 3411 forms a line contact with the outer circumferential surface of the workpiece 5. The inner wall of the positioning step 3411 is provided with anti-slip protrusions.

[0036] The pressure component 35 includes a pneumatic cylinder 351, a pressure transmission plate 352, and an elastic compensation layer 353. The bottom surface of the pressure transmission plate 352 is provided with a wavy toothed surface, and the elastic compensation layer 353 is fixed to the bottom of the pressure transmission plate 352 by a detachable snap fastener.

[0037] In this application, the operator can rotate the L-shaped clamping arm 341. Under the combined action of the rotating shaft 342 and the torsion spring 343, the L-shaped clamping arm 341 has a certain elasticity and self-resetting ability. The stepped positioning step 3411 forms a line contact with the outer circumferential surface of the workpiece 5. The anti-slip protrusions can increase the friction with the surface of the workpiece 5, so that the workpiece 5 can be clamped by the clamping arm and the workpiece 5 can be stably installed. In addition, the pneumatic cylinder 351 provides a stable pressure source, the pressure transmission plate 352 distributes the pressure evenly to the surface of the workpiece 5, and the elastic compensation layer 353 can compensate for the pressure difference caused by the unevenness or slight deformation of the surface of the workpiece 5, ensuring that the workpiece 5 always maintains a stable and uniform force state during the grinding process. In addition, the setting of the wavy toothed surface also enhances the friction between the pressure transmission plate 352 and the workpiece 5, further improving the installation stability of the workpiece 5.

[0038] Referring to Figure 2, the rotary grinding wheel 4 includes a grinding head 41, a starter motor 42, and a base 43. The grinding head 41 is mounted on one end of the base 43 near the moving mechanism 2 via a shaft connection. The output end of the starter motor 42 is mounted on the grinding head 41 to drive the grinding head 41 to rotate. In this application, the rotary grinding wheel 4 also includes a transverse moving component 44 disposed at the bottom of the base 43. The transverse moving component 44 includes a rodless cylinder and a moving seat, so that the entire base 43 is mounted on the top surface of the moving seat. The moving seat slides against the slide rail of the rodless cylinder, which can realize the position adjustment of the rotary grinding wheel 4. The transverse moving component 44 in this application can be replaced by other mechanisms in the prior art, as long as the rotary grinding wheel 4 is in a horizontal position and this direction is perpendicular to the movement direction of the workpiece 5.

[0039] The above are all preferred embodiments of this application. These embodiments are merely explanations 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.
