Description

Technical Field

[0001] This utility model relates to the field of motor shaft machining technology, and in particular to a grinding machine for machining motor shafts. Background Technology

[0002] The motor shaft is one of the core components of an electric motor, and its machining accuracy and surface quality directly affect the motor's performance, lifespan, and reliability. Grinding is a key process in the machining of motor shafts, as it can achieve extremely high dimensional accuracy, which is difficult to achieve with ordinary turning, milling, and other processes.

[0003] Existing grinding machines for motor shaft machining spray coolant during grinding to dissipate heat and lower the temperature, thus preventing the surface temperature of the parts and the grinding wheel from becoming too high. However, due to the lack of a filtration structure, it is impossible to separate waste chips from the coolant, resulting in a large amount of waste chips mixed in with the coolant, which affects the effectiveness of the coolant and brings certain adverse effects to the user experience. In order to overcome the shortcomings of the existing technology, we propose a grinding machine for motor shaft machining. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-3 As shown, a grinding machine for machining motor shafts includes a worktable 1. A first fixed frame 2, a second fixed frame 3, and a third fixed frame 4 are welded to the upper end of the worktable 1. A nozzle 5 is detachably connected to the lower end of the first fixed frame 2. A water pipe 7 is detachably connected to the right side of the nozzle 5. A water pump 8 is detachably connected to the lower end of the water pipe 7. A water tank 6 is provided in front of the water pump 8.

A limit frame 11 is welded to the upper end of the filter screen frame 12. Two sets of slots 13 are provided inside the water tank 6. Two sets of insertion rods 20 are welded to the lower end of the worktable 1.

[0022] Through the structure of water tank 6 and filter frame 12, water pump 8 can pump the liquid inside water tank 6 into nozzle 5. Nozzle 5 sprays out the liquid to cool the grinding position, so that the temperature of the motor shaft surface and the grinding wheel surface of the grinding head will not be too high. Filter frame 12 filters waste chips, and the sprayed liquid can re-enter water tank 6. Users can disassemble filter frame 12 and water tank 6 for easy cleaning. The disassembly method is simple, and the device is highly practical.

[0023] Example 2, as Figure 1 as well as Figure 4 As shown, a grinding machine for machining motor shafts has a second fixed frame 3 with a motor 9 detachably connected to its front end. A first adjusting screw 15 is detachably connected to one end of the motor 9. A connecting sleeve 17 is welded to the rear end of the first adjusting screw 15. A second adjusting screw 16 is welded to the rear end of the connecting sleeve 17. A movable frame 14 is threadedly connected to the outer walls of both the second adjusting screw 16 and the first adjusting screw 15. A balance bar 18 is movably connected inside the movable frame 14. A second connecting frame 19 is detachably connected to the front side of the movable frame 14. The moving component along the y-axis at the lower end of the grinding assembly 21 consists of a motor, a balance bar, and a screw.

[0024] Through the structure of the first adjusting screw 15 and the second adjusting screw 16, the motor 9 drives the first adjusting screw 15 to rotate, so that the two sets of movable frames 14 can move in opposite directions at the same time. The user can clamp motor shafts of different diameters between the two sets of second connecting frames 19. Furthermore, the user can replace the second connecting frame 19 according to the diameter of the motor shaft, so that the arc-shaped hole inside the second connecting frame 19 can fit with the motor shaft. The device can clamp and fix motor shafts of different diameters, thus improving the applicability of the device.

[0025] It should be noted that this utility model is a grinding machine for processing motor shafts.

The user can clamp motor shafts of different diameters between the two sets of second connecting frames 19. Furthermore, the user can replace the second connecting frame 19 according to the diameter of the motor shaft, so that the arc-shaped hole inside the second connecting frame 19 can fit with the motor shaft. When the grinding assembly 21 grinds the motor shaft, the water pump 8 can pump the liquid inside the water tank 6 into the nozzle 5 through the water pipe 7. The nozzle 5 sprays out the liquid to cool the grinding position, so that the temperature of the surface of the motor shaft and the surface of the grinding wheel of the grinding head will not be too high. In addition, the filter frame 12 filters the waste chips. The sprayed liquid can return to the water tank 6 through the square hole inside the worktable 1.
