Description

Technical Field

[0001] This utility model belongs to the technical field of shaft workpiece processing equipment, specifically relating to a multi-station lathe for machining motor shafts. Background Technology

[0002] As a key component of a motor, the motor shaft plays a crucial role in the electromechanical energy conversion between the motor and the equipment. It not only supports rotating parts and effectively transmits torque, but also precisely determines the position of rotating parts relative to the stator. Therefore, the motor shaft must possess stable and reliable strength and rigidity to ensure the perfect realization of its pre-designed functions. Multi-station lathes for motor shaft machining are efficient and precise automated processing equipment that achieves high-precision and high-efficiency machining of motor shafts through multi-station collaborative operation.

[0003] Chinese utility model patent (application number 202221001615.2) discloses a multi-station lathe for machining motor shafts, including a lathe body, and a left bed and a right bed slidably mounted on the lathe body. The rotating bracket mounted on the left bed rotates 90 degrees each time, which drives the chuck with the fixed motor shaft to move to four fixed mounting positions set on the right bed for different processes, so as to realize the synchronous machining of multiple motor shafts.

[0004] Existing multi-station lathes for motor shaft machining, while capable of multi-station collaborative processing, still heavily rely on manual operation in the material loading stage. This manual loading method not only increases the labor intensity of operators but also leads to unstable loading speed due to human factors, thus restricting the overall processing efficiency of motor shafts to a certain extent. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-station lathe for machining motor shafts, which aims to solve the problem that the loading process of multi-station lathes for machining motor shafts still relies heavily on manual operation. This manual loading method not only increases the labor intensity of operators, but also causes unstable loading speed due to human factors, which to some extent restricts the overall machining efficiency of motor shafts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station lathe for machining motor shafts, comprising a base plate, a first bed and a second bed slidably connected to the upper surface of the base plate, a rotary drive seat mounted on the side surface of the first bed and penetrating therethrough, a drive motor mounted on the side surface of the rotary drive seat, a connector connected to the output end of the drive motor, a clamping fixture for the motor shaft connected to the end of the connector, and a tool holder mounted on the surface of the base plate for machining the motor shaft. A motor shaft storage bin for storing motor shafts is fitted onto the surface of the second bed. A loading assembly is provided on the bottom side of the motor shaft storage bin and installed inside the second bed. A guide assembly is connected between the loading assembly and the motor shaft storage bin. A unloading assembly penetrating inside the clamping fixture is connected inside the cavity of the connector. A side plate is connected to the side surface of the first bed, and a movable receiving assembly is connected to the surface of the side plate.

[0007] As a multi-station lathe for machining motor shafts according to the present invention, preferably, the feeding assembly includes a first telescopic rod, a first push rod and a material groove. The first telescopic rod is installed on the side surface of the second bed and extends to the inside. The movable end of the first telescopic rod is connected to a guide assembly that passes through the second bed. The surface of the guide assembly is opened in the material groove located directly below the motor shaft material bin. The position of the material groove corresponds to the position of the highest clamping seat slot.

[0008] As a multi-station lathe for machining motor shafts according to this utility model, preferably, the guiding assembly includes a guide rail and a guide sleeve. The guide rail is connected to both sides of the bottom end of the motor shaft hopper, and the two sides of the first push rod are respectively connected to guide sleeves adapted to the guide rail.

[0009] As a multi-station lathe for machining motor shafts according to this utility model, preferably, the blanking assembly includes a second telescopic rod and a second push rod. The second telescopic rod is installed inside the connecting cavity, and the movable end of the second push rod is connected to a second push rod that passes through the center of the clamping seat.

[0010] As a multi-station lathe for machining motor shafts according to this utility model, preferably, the movable receiving assembly includes a third telescopic rod and a receiving groove. The third telescopic rod is installed on the upper surface of the side plate, and the movable end of the third telescopic rod is connected to the receiving groove. When the third telescopic rod drives the receiving groove to move to the farthest end of its travel, it is located on the outer side of the farthest end of the lateral direction of the clamp. The highest point of the receiving groove is flush with the lowest point of the clamp slot in the middle position.

[0011] As a multi-station lathe for machining motor shafts according to this utility model, preferably, the movable receiving assembly further includes a vertical plate connected to the upper surface of the side plate and a guide rod connected to the side wall of the receiving groove and penetrating the vertical plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the motor shaft inside the motor shaft hopper falls into the material trough. When the first telescopic rod extends, it drives the motor shaft inside to move laterally through the first push rod and the material trough. After the first push rod drives the motor shaft to be inserted into the slot of the clamp, it can be clamped. This can realize automatic feeding of the motor shaft, thereby improving the processing efficiency of the motor shaft and reducing the processing cost of the motor shaft.

[0014] In this invention, the highest-end clamp drives the clamped motor shaft to rotate 270° and then the third telescopic rod moves. When the third telescopic rod retracts, it can drive the guide groove to move closer to the clamp. When the guide groove moves to the bottom side of the clamp, the clamp releases the clamp from the motor shaft and the second telescopic rod moves. When the second telescopic rod moves, it can squeeze the second push rod to move laterally and squeeze the motor shaft out of the clamp. At this time, the motor shaft can fall into the guide groove and slide down, thereby realizing the centralized collection of the motor shaft and avoiding the need for manual unloading, which increases the labor intensity of employees.

[0023] 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.

[0024] Please see Figures 1-6 The present invention provides the following technical solution: a multi-station lathe for machining motor shafts, comprising a base plate 1, a first bed 2 and a second bed 14 slidably connected to the upper surface of the base plate 1, a rotary drive seat 3 mounted on the side surface of the first bed 2 and penetrating therethrough, a drive motor 4 mounted on the side surface of the rotary drive seat 3, a connector 5 connected to the output end of the drive motor 4, a clamping seat 6 for the motor shaft connected to the end of the connector 5, and a tool holder 7 mounted on the surface of the base plate 1 for machining the motor shaft. A motor shaft storage bin 8 for storing motor shafts is fitted onto the surface of the second bed 14. A loading assembly 9 is provided on the bottom side of the motor shaft storage bin 8 and installed inside the second bed 14. A guide assembly 10 is connected between the loading assembly 9 and the motor shaft storage bin 8. A unloading assembly 11 penetrating inside the clamping seat 6 is connected inside the cavity of the connector 5. A side plate 12 is connected to the side surface of the first bed 2, and a movable receiving assembly 13 is connected to the surface of the side plate 12.

[0025] First, the motor shaft is inserted into the slot of the highest clamping seat 6 and clamped. Then, the surface clamping seat 6 is rotated by the rotation drive seat 3. After the rotation drive seat 3 rotates 90°, the highest clamping seat 6 at this position can clamp the motor shaft and process the first clamped motor shaft. Then, the rotation processing continues.

[0026] Preferably, the feeding assembly 9 includes a first telescopic rod 901, a first push rod 902, and a material trough 903. The first telescopic rod 901 is installed on the side surface of the second bed 14 and extends to the inside. The movable end of the first telescopic rod 901 is connected to a guide assembly 10 that passes through the second bed 14. The surface of the guide assembly 10 is opened in the material trough 903 located directly below the motor shaft material bin 8. The position of the material trough 903 corresponds to the position of the slot of the highest clamping seat 6.

[0027] In practical use, when the first telescopic rod 901 extends, it can squeeze the first push rod 902 to move laterally, and when the first push rod 902 moves laterally, it can move towards the clamping seat 6 at the highest point.

[0028] Preferably, the guide assembly 10 includes a guide rail 1001 and a guide sleeve 1002. The guide rail 1001 is connected to both sides of the bottom end of the motor shaft hopper 8, and the two sides of the first push rod 902 are respectively connected to the guide sleeves 1002 that are adapted to the guide rail 1001.

[0029] In practical use, when the first push rod 902 is subjected to a force, it can drive the guide sleeve 1002 to slide on the surface of the guide rail 1001, which can limit the movement direction of the first push rod 902 and maintain the stability of the movement of the first push rod 902.

[0030] Preferably, the feeding assembly 11 includes a second telescopic rod 1101 and a second push rod 1102. The second telescopic rod 1101 is installed inside the cavity of the connector 5, and the movable end of the second push rod 1102 is connected to a second push rod 1102 that passes through the center of the clamping seat 6.

[0031] In practical use, after the clamping seat 6 contacts the motor shaft, the second telescopic rod 1101 can squeeze the second push rod 1102 to move laterally when it runs. When the second telescopic rod 1101 moves laterally, it can push the motor shaft to the outside of the clamping seat 6.

[0032] Preferably, the movable receiving assembly 13 includes a third telescopic rod 1301 and a receiving groove 1302. The third telescopic rod 1301 is installed on the upper surface of the side plate 12. The movable end of the third telescopic rod 1301 is connected to the receiving groove 1302. When the third telescopic rod 1301 drives the receiving groove 1302 to move to the farthest end of its travel, it is located outside the farthest end of the lateral direction of the clamp 6. The highest point of the receiving groove 1302 is flush with the lowest point of the slot of the clamp 6 in the middle position.

[0033] In practical use, when the third telescopic rod 1301 retracts, it can drive the receiving groove 1302 to move laterally, thus adjusting the position of the receiving groove 1302.

[0034] Preferably, the movable receiving assembly 13 further includes a vertical plate 1303 connected to the upper surface of the side plate 12 and a guide rod 1304 connected to the side wall of the receiving groove 1302 and passing through the vertical plate 1303;

[0035] In practical use, when the guide groove 1302 moves laterally, it can drive the guide rod 1304 to slide inside the vertical plate 1303, thus maintaining the stability of the movement of the guide groove 1302.

[0036] The working principle of this utility model in specific use is as follows: When using this lathe, the motor shaft can be stored inside the motor shaft bin 8. The bottom motor shaft will fall into the material groove 903 through the opening at the bottom of the motor shaft bin 8. Then, the first telescopic rod 901 can be run. When the first telescopic rod 901 extends, it can squeeze the first push rod 902. When the first push rod 902 is squeezed, it can drive the motor shaft inside to move laterally through the material groove 903. After the first push rod 902 drives the motor shaft to be inserted into the slot of the clamp 6, it can be clamped. Then, the first telescopic rod 901 retracts and drives the first push rod 902 to reset. At this time, the motor shaft at the bottom of the motor shaft bin 8 will still fall into the material groove 903. This cycle can realize the automatic feeding of motor shafts.

[0037] When the highest-end clamp 6 drives the clamped motor shaft to rotate 90° and 180°, processing can be performed. When the clamp 6 drives the clamped motor shaft to rotate 270°, the third telescopic rod 1301 can be operated. When the third telescopic rod 1301 retracts, it can drive the receiving groove 1302 to move closer to the clamp 6. When the receiving groove 1302 moves to the bottom side of the clamp 6, the clamp 6 can be released from clamping the motor shaft and the second telescopic rod 1101 can be operated. When the second telescopic rod 1101 is running, it can squeeze the second push rod 1102 to move laterally and squeeze the motor shaft out of the clamp 6. At this time, the motor shaft can fall into the receiving groove 1302 and slide down, thereby realizing the centralized collection of the motor shaft.

[0038] 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.
