Description

Technical Field

[0001] This utility model relates to the technical field of the automotive parts manufacturing industry, and in particular to a lathe for machining motor end caps. Background Technology

[0002] With the development of the times, electric motors have been widely used in the automotive industry. The motor end cover is a cover that covers the top of the motor. It is usually made of materials such as metal and plastic. It is an important part of the motor and is used to enclose the internal structure of the motor rotor and stator to protect the internal components of the motor from the influence of the external environment. The motor end cover can also fix the stator and rotor so that they can operate in a predetermined manner.

[0003] Currently, the machining of motor end caps is carried out on a lathe. In order to prevent the end caps on the lathe from moving during the machining process, a clamping device is often set on the lathe to fix the end caps.

[0004] In related technologies, most clamping devices on lathes currently consist of a combination of multiple pressure plates to press the end cap onto the lathe. While this method can achieve the effect of fixing the end cap, since the pressure plates are mostly located at the top when pressing the end cap, the end cap only bears force at the top, and the direction of force is relatively singular. During the machining process, the end cap may slide due to excessive force, which may lead to damage to the end cap. Utility Model Content

[0005] To address the problem that the current method of fixing motor end caps on lathes involves a single stress point, which makes them prone to slippage and damage, this invention provides a lathe for machining motor end caps.

[0006] The lathe for machining motor end caps provided by this utility model adopts the following technical solution:

[0007] A lathe for machining motor end caps, comprising:

[0008] A lathe support base, wherein a motor end cover is provided on the lathe support base, and a mounting groove is provided on the side wall of the lathe support base;

[0009] An end cap locking mechanism is provided within the mounting groove. The end cap locking mechanism includes a support plate, a linkage rod, a mating plate, a top abutment plate, a mating groove, and a side abutment plate. The support plate is rotatably connected to the bottom of the mounting groove. The linkage rod is fixed to the support plate. The mating plate is fixed to one end of the linkage rod away from the support plate. The top abutment plate is located at the top of the linkage rod and above the motor end cap. The mating groove extends through the top abutment plate, and the mating plate is rotatably connected within the mating groove. One end of the side abutment plate is fixed to the support plate, and the other end abuts against the side wall of the motor end cap.

[0010] By adopting the above technical solution and utilizing the end cover locking mechanism, the top and side of the motor end cover can be simultaneously abutted and locked by the top abutment plate and the side abutment plate. The top abutment plate and the side abutment plate enable the motor end cover to be subjected to axial and radial forces after being locked, increasing the force direction of the motor end cover. This effectively avoids the situation where the motor end cover may slip during processing due to the relatively unidirectional force direction, leading to processing failure or even damage to the motor end cover.

[0011] Optionally, the end cap locking mechanism is provided with a linkage mechanism, which includes a driven cylinder, a push-pull rod, and a transmission rod. The driven cylinder is slidably sleeved on the outside of the linkage rod. One end of the push-pull rod and the transmission rod are rotatably connected to each other, and the other end of the push-pull rod is rotatably connected to the driven cylinder. The other end of the transmission rod is fixed to the top abutment plate.

[0012] By adopting the above technical solution, the sliding of the driven cylinder drives the push-pull rod to rotate, and then drives the top abutment plate to rotate through the transmission rod, so that the top abutment plate and the side abutment plate can synchronously abut against the motor end cover.

[0013] Optionally, the linkage mechanism further includes a cylinder, the fixed part of which is rotatably connected to the bottom of the mounting groove, and the telescopic part of which is rotatably connected to the driven cylinder.

[0014] By adopting the above technical solution, the extension and retraction of the cylinder extension part drives the support plate to rotate and the driven cylinder to slide, thereby enabling the top abutment plate and the side abutment plate to move in sync.

[0015] Optionally, a return spring is also sleeved on the outside of the linkage rod. One end of the return spring abuts against the driven cylinder, and a chuck is provided at the top of the linkage rod. The other end of the return spring abuts against the chuck.

[0016] By adopting the above technical solution, the elastic force of the return spring is used to assist the driven cylinder in quickly resetting.

[0017] Optionally, the top edge of the lathe support is provided with a screw hole, and multiple screw holes are provided at equal intervals, with a positioning rod provided in each screw hole.

[0018] By adopting the above technical solution, the positioning rod is used to achieve the positioning function of the motor end cover.

[0019] Optionally, both the top abutment plate and the side abutment plate are provided with an abutment joint at one end near the motor end cover, and the abutment joint is detachably connected to the top abutment plate and the side abutment plate by screws.

[0020] By adopting the above technical solution, the abutment is used to abut the motor end cover, which avoids damage to the motor end cover and also allows the staff to quickly replace the abutment.

[0021] Optionally, the overall structure formed by the combination of the end cap locking mechanism and the linkage mechanism is provided in multiple sets on the lathe support, and is symmetrically arranged, and the multiple cylinders are uniformly controlled by an external control device.

[0022] By adopting the above technical solution and utilizing the setting of multiple combined structures, the motor end cover can be evenly stressed around.

[0023] In summary, this utility model has at least one of the following beneficial technical effects:

[0024] By utilizing the end cap locking mechanism, the top and sides of the motor end cap can be simultaneously abutted and locked by the top abutment plate and the side abutment plate. The top and side abutment plates allow the motor end cap to be subjected to axial and radial forces after locking, increasing the force direction and effectively preventing slippage during processing, which could lead to processing failure or even damage to the motor end cap due to a unidirectional force direction. Furthermore, the linkage mechanism utilizes the extension and retraction of the cylinder to drive the support plate to rotate and the driven cylinder to slide, enabling the top and side abutment plates to move synchronously and abut against the motor end cap.

[0034] Reference Figure 1 and Figure 2 A lathe for machining motor end caps includes a lathe support 1, a motor end cap 2, a mounting groove 3, an end cap locking mechanism 4, and a linkage mechanism 5. The motor end cap 2 is mounted on the lathe support 1, and the mounting groove 3 is provided on the side wall of the lathe support 1. The end cap locking mechanism 4 is disposed in the mounting groove 3, and the linkage mechanism 5 is provided on the end cap locking mechanism 4. By utilizing the end cap locking mechanism 4, the top and side of the motor end cap 2 can be simultaneously abutted and locked by the top abutment plate 44 and the side abutment plate 46. The top abutment plate 44 and the side abutment plate 46 enable the motor end cover 2 to be subjected to axial and radial forces after being locked, increasing the force direction of the motor end cover 2. This effectively avoids the possibility of slippage during processing due to the relatively unidirectional force direction of the motor end cover 2, which could lead to processing failure or even damage to the motor end cover 2. Furthermore, the linkage mechanism 5 enables the top abutment plate 44 and the side abutment plate 46 to move synchronously and abut against the motor end cover 2.

[0035] Specifically, the end cap locking mechanism 4 includes a support plate 41, a linkage rod 42, a docking plate 43, a top abutment plate 44, a docking slot 45, and a side abutment plate 46. The support plate 41 is rotatably connected to the bottom of the mounting slot 3. The linkage rod 42 is fixed on the support plate 41. The docking plate 43 is fixed on the linkage rod 42 at one end away from the support plate 41. The top abutment plate 44 is located at the top of the linkage rod 42 and above the motor end cap 2.

One end of the side abutment plate 46 is fixed on the support plate 41, and the other end abuts against the side wall of the motor end cap 2.

[0036] Reference Figure 3 Specifically, in this embodiment of the present invention, the linkage mechanism 5 includes a driven cylinder 51, a push-pull rod 52, a transmission rod 53, and a cylinder 54. The extension and retraction of the cylinder 54 pushes the support plate 41 to rotate and the driven cylinder 51 to slide, thereby enabling the top abutment plate 44 and the side abutment plate 46 to be linked synchronously and abut against the motor end cover 2.

[0037] The driven cylinder 51 is slidably sleeved on the outside of the linkage rod 42. One end of the push-pull rod 52 and the transmission rod 53 are rotatably connected to each other, and the other end of the push-pull rod 52 is rotatably connected to the driven cylinder 51. The other end of the transmission rod 53 is fixed on the top abutment plate 44. The fixed part of the cylinder 54 is rotatably connected to the bottom of the mounting groove 3, and the telescopic part of the cylinder 54 is rotatably connected to the driven cylinder 51.

[0038] In this embodiment of the utility model, a return spring 7 is also sleeved on the outside of the linkage rod 42. One end of the return spring 7 abuts against the driven cylinder 51, and a chuck 6 is provided at the top of the linkage rod 42. The other end of the return spring 7 abuts against the chuck 6. The elastic force of the return spring 7 is used to assist the driven cylinder 51 to quickly return to its original position.

[0039] Reference Figure 4 Specifically, in this embodiment of the present invention, a screw hole 8 is provided at the top edge of the lathe support 1, and multiple screw holes 8 are provided at equal intervals. A positioning rod 9 is provided in the screw hole 8, and the positioning rod 9 is used to achieve the positioning function of the motor end cover 2.

[0040] In this embodiment of the utility model, abutment 10 is provided on one end of the top abutment plate 44 and the side abutment plate 46 near the motor end cover 2. The abutment 10 is detachably connected to the top abutment plate 44 and the side abutment plate 46 by screws. The abutment 10 is used to abut against the motor end cover 2 to avoid damage to the motor end cover 2, and at the same time, it allows the staff to quickly replace the abutment 10.

[0041] Specifically, the overall structure consisting of the end cover locking mechanism 4 and the linkage mechanism 5 is provided in multiple sets on the lathe support seat 1 and is symmetrically arranged. Multiple cylinders 54 are uniformly controlled by external control equipment. By using the arrangement of multiple sets of combined structures, the motor end cover 2 can be evenly stressed around.

[0042] The implementation principle of a lathe for machining motor end covers according to this utility model embodiment is as follows: First, the positioning rod 9 is connected in the screw hole 8. Then, the motor end cover 2 is placed on the top of the lathe support seat 1 and positioned by the positioning rod 9. Then, the telescopic part of the cylinder 54 is controlled to extend. During the extension process, the support plate 41 rotates and drives one end of the lateral abutment plate 46 to abut against the side wall of the motor end cover 2. At the same time, the driven cylinder 51 slides on the linkage rod 42 and drives the top abutment plate 44 to rotate through the push-pull rod 52 and the transmission rod 53, so that one end of the top abutment plate 44 abuts against the top of the motor end cover 2, thereby locking the motor end cover 2.
