Description

Technical Field

[0001] This utility model belongs to the technical field of shaft workpiece processing equipment, specifically relating to a motor shaft keyway processing device. Background Technology

[0002] The output shaft of a motor needs to be reliably connected to other components (such as gears, pulleys, couplings, etc.), and keyed connections are the most common type of mating. Therefore, in the machining process of the motor shaft, milling the keyway becomes a key step to ensure mating accuracy and transmission stability.

[0003] In the conventional production process of keyway machining of motor shafts, the loading process still relies on manual operation. Workers need to place the motor shafts to be processed one by one on the positioning fixture of the processing equipment and manually adjust the axial position to ensure the accuracy of the processing reference. This loading method, which relies entirely on manual operation, is not only time-consuming, but also affected by the operator's proficiency and fatigue level, making it difficult to improve the overall processing efficiency.

[0004] Based on this, a keyway machining device for motor shafts is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figures 1-6 This utility model provides the following technical solution: a keyway machining device for motor shafts, comprising:

[0043] Mounting base 100, with a slotted assembly 101 mounted on its upper surface, a clamping and fixing mechanism 200 on its surface, a feeding mechanism 300 and a turning mechanism 600 mounted on its upper surface, a drive mechanism 400 connected to the upper surface of mounting base 100 inside the clamping and fixing mechanism 200, and a guide mechanism 500 connected to the upper surface of mounting base 100 on the side surface of the clamping and fixing mechanism 200.

[0044] Preferably, the clamping and fixing mechanism 200 includes a fixing base 201, a slot 202, a first push rod 203, and a fixing plate 204;

[0045] Two sets of card slots 202, first push rods 203 and fixed card plates 204 are symmetrically arranged;

[0046] The inner wall of the fixing base 201 has slots 202 located directly below the two fixing plates 204, and the top of the fixing base 201 is respectively equipped with a first push rod 203 that is connected to the two fixing plates 204.

[0047] In practical use, after the motor shaft is inserted between the fixing plate 204 and the slot 202, the first push rod 203 is run. When the first push rod 203 extends, it can drive the fixing plate 204 to move downward. When the fixing plate 204 moves downward to the surface of the motor shaft, the position of the motor shaft can be fixed by the squeezing of the fixing plate 204.

[0048] Preferably, the feeding mechanism 300 includes a storage rack 301, a guide hole 302, a bracket 303, and a second push rod 304;

[0049] The storage rack 301 is installed on the upper surface of the mounting base 100, and the cross-sectional dimensions of the mounting base 100 are adapted to the dimensions of the motor shaft;

[0050] The guide hole 302 is opened on the side surface of the bottom of the storage rack 301 and is flush with the bottom of its inner wall. The diameter of the guide hole 302 is adapted to the diameter of the motor shaft.

[0051] The bracket 303 is connected to the upper surface of the mounting base 100;

[0052] The second push rod 304 is installed on the upper surface of the bracket 303. The center line of the second push rod 304 coincides with the central axis of the guide hole 302, and the telescopic shaft of the second push rod 304 is adapted to the size of the guide hole 302.

[0053] In practical use, when the second push rod 304 extends, it can squeeze the motor shaft at the bottom of the storage rack 301. When the motor shaft is squeezed, it can move laterally to the outside of the storage rack 301. When the motor shaft moves to the surface of the fixed seat 201 through the guide hole 302, the automatic feeding of the motor shaft can be realized.

[0054] Preferably, the drive mechanism 400 includes a drive motor 401, a screw 402, and a bearing housing 403;

[0055] The drive motor 401 is mounted on the upper surface of the mounting base 100;

[0056] The screw 402 is connected to the output shaft end of the drive motor 401, and the screw 402 passes through the inside of the fixed base 201 and is threadedly connected to it;

[0057] The bearing housing 403 is mounted on the upper surface of the mounting base 100, and the screw 402 is connected through the inside of the bearing housing 403.

[0058] In practical use, when the drive motor 401 is running, it can drive the screw 402 to rotate. When the screw 402 rotates, it can drive the clamping and fixing mechanism 200 to move laterally through the threaded connection. When the clamping and fixing mechanism 200 moves laterally, it can drive the motor shaft to move laterally. This allows the position of the motor shaft to be adjusted, making it convenient to slot the surface of the motor shaft.

[0059] Preferably, the guiding mechanism 500 includes a guide plate 501 and a guide strip 502;

[0060] The guide plate 501 is connected to the upper surface of the mounting base 100, and the guide plate 501 has elongated grooves on both sides.

[0061] The guide strip 502 is connected to both sides of the fixed base 201, and the horizontal part of the guide strip 502 is located inside the elongated groove of the guide plate 501.

[0062] In practical use, when the clamping and fixing mechanism 200 is subjected to force, it can drive the guide strip 502 to slide axially in the groove of the guide plate 501. This can limit the movement direction of the clamping and fixing mechanism 200, thereby ensuring the stability of the sliding of the clamping and fixing mechanism 200.

[0063] Preferably, the steering mechanism 600 includes a vertical plate 601, a power motor 602, a turntable 603, a third push rod 604, a clamping plate 605, and a rubber pad 606;

[0064] The upright plate 601 is vertically connected to the upper surface of the mounting base 100;

[0065] The power motor 602 is mounted on the side surface of the upright plate 601, and the output shaft of the power motor 602 extends to the other side of the upright plate 601;

[0066] The output shaft of the power motor 602 is connected to a turntable 603;

[0067] The third push rod 604 is installed on the side surface of the turntable 603, and two third push rods 604 are symmetrically arranged.

[0068] The clamping plate 605 is connected to the movable end of the third push rod 604, and two clamping plates 605 are symmetrically arranged.

[0069] Rubber gaskets 606 are connected to the inner wall of clamping plate 605, and two rubber gaskets 606 are symmetrically arranged.

[0070] In practical use, after the end of the motor shaft moves between the two clamping plates 605, the third push rod 604 is activated. When the third push rod 604 is activated, it can drive the clamping plates 605 to move closer to the motor shaft. When the clamping plates 605 drive the rubber pad 606 to the surface of the motor shaft, the rubber pad 606 can be clamped. At this time, the clamping and fixing mechanism 200 releases the motor shaft and activates the power motor 602. When the power motor 602 is activated, it can drive the turntable 603 to rotate. When the turntable 603 rotates, it can drive the motor shaft to rotate through the third push rod 604, the clamping plates 605 and the rubber pad 606.

[0071] Preferably, the upright plate 601, the fixed base 201, the storage rack 301, the second push rod 304 and the milling cutter of the slotting assembly 101 share a central axis surface.

[0072] The working principle of this utility model is as follows: When using the motor shaft keyway processing device, the motor shaft is first stored in the storage rack 301. Then, the second push rod 304 can be run. When the second push rod 304 extends, it can squeeze the motor shaft at the bottom of the storage rack 301. When the motor shaft is squeezed, it can move laterally and move laterally through the guide hole 302 to the surface of the slot 202. Then, the second push rod 304 is retracted. When the second push rod 304 is reset, the motor shaft is lowered to the bottom side of the inner wall of the storage rack 301.

[0073] Next, the first push rod 203 can be operated. When the first push rod 203 is running, it can drive the fixed plate 204 to move downward. When the fixed plate 204 moves downward to the surface of the motor shaft, the motor shaft can be clamped and fixed.

[0074] Then the drive motor 401 can be run. When the drive motor 401 runs, it can drive the screw 402 to rotate. Under the limiting action of the guide plate 501 and the guide strip 502, the rotation of the screw 402 can drive the motor shaft to move laterally through the clamping and fixing mechanism 200. When the clamping and fixing mechanism 200 drives the motor shaft to move to the bottom side of the grooving assembly 101, the power mechanism of the grooving assembly 101 drives the milling cutter to rotate. Then, by controlling the height of the milling cutter, the surface of the motor shaft can be grooved.

[0075] When grooving is required in the other direction of the motor shaft, the clamping and fixing mechanism 200 can be controlled to move laterally by the drive mechanism 400. When the clamping and fixing mechanism 200 drives the end of the motor shaft to move between the two clamping plates 605, the third push rod 604 is activated. When the third push rod 604 drives the rubber pad 606 to move to the surface of the motor shaft through the clamping plate 605, it can clamp the motor shaft. Then the first push rod 203 drives the fixing plate 204 to move upward, and then the power motor 602 can be activated. When the power motor 602 rotates, it can drive the motor shaft to rotate through the turntable 603, the third push rod 604, the clamping plate 605 and the rubber pad 606. After the motor shaft rotates, the first push rod 203 drives the fixing plate 204 to move downward and clamp and fix the motor shaft. Then the third push rod 604 drives the clamping plate 605 to retract. This can realize the rotation of the motor shaft, thereby realizing grooving in different directions of the motor shaft.

[0076] After the grooving is completed, the drive mechanism 400 drives the clamping and fixing mechanism 200 to move to the starting position. Then, the second push rod 304 can be controlled to continue running. When the second push rod 304 extends, it squeezes the motor shaft to move laterally. When the motor shaft moves laterally, it can squeeze the grooved motor shaft to move away from the clamping and fixing mechanism 200. When the motor shaft moves to the predetermined position, it can squeeze the grooved motor shaft off the clamping and fixing mechanism 200 to realize the material dropping.

[0077] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
