Description

Technical Field

[0001] The utility model relates to the technical field of shaft workpiece processing equipment, and particularly relates to a tapping machine for motor shaft processing. Background Technique

[0002] The motor shaft is an important part in the motor. As a link for electromechanical energy conversion between the motor and the equipment, the motor shaft supports rotating parts, transmits torque, and determines the relative position of the rotating parts to the stator. During the processing of the motor shaft, it is often necessary to use a tapping machine to perform tapping processing on it to meet the requirements for later assembly and use.

[0003] In the prior art, for example, a tapping machine disclosed in a Chinese utility model patent (the authorization announcement number is: CN220782495U) for mechanical numerical control processing has a structure including a device plate body, and further includes: a first motor, which is connected to the bottom of the device plate body by screws; a multi-angle tapping mechanism, which is rotatably connected to the top of the first motor and can adjust the position angle of the tapping through the multi-angle tapping mechanism, so as to tap parts at different positions, improving the tapping efficiency. The multi-angle tapping mechanism includes a first motor shaft, and the bottom of the first motor shaft is connected to a first motor. This tapping machine not only can drive the rotating rod, the fixed strip plate and the tapping to rotate by the first motor shaft through the rotating rod on the first motor shaft and the second motor at the bottom of the fixed strip plate, so as to tap multiple parts placed on the top of the device plate body respectively, improving the tapping efficiency.

[0004] However, during the use of the above-mentioned tapping machine disclosed in the prior art, although it can drive the rotating rod, the fixed strip plate and the tapping to rotate by the first motor shaft through the rotating rod on the first motor shaft and the second motor at the bottom of the fixed strip plate, so as to tap multiple parts placed on the top of the device plate body respectively and improve the tapping efficiency, in actual application, this tapping machine directly places the parts or motor shafts to be tapped on the top of the plate body without fixing the positions of the parts to be tapped, resulting in the problem that the parts are likely to move randomly during tapping, leading to tapping failure or tapping breakage, and due to the high temperature at the tapping position and without cooling it, the problem of part deformation is likely to occur.

[0005] Therefore, it is necessary to improve the prior art. Content of the Utility Model

[0010] Preferably, the bottom of the sleeve is rotatably installed inside the operating table, and the worm gear is meshed with the worm, which is convenient for realizing the stable rotation of the sleeve and avoiding the phenomenon that the sleeve still rotates after the motor shaft is fixed.

[0011] Preferably, four groups of the first connecting rod, the limiting frame, the second connecting rod and the positioning plate are provided. The first connecting rod and the second connecting rod are rotatably installed. The first connecting rod is arranged in an "L" shape, which is convenient for clamping and positioning the motor shaft to be tapped, ensuring stable machining and reducing the phenomenon of the tapping head breaking.

[0012] Preferably, the auxiliary cooling mechanism includes a liquid storage tank for storing coolant. A liquid injection pipe is fixedly installed at the top of the liquid storage tank.

[0026] Furthermore, support legs are arranged at the bottom of the operating table 1, an installation groove is opened inside the support frame 2, and a replaceable tap head is arranged in the thread tapping device 4, which is convenient for quickly disassembling and replacing the tap head when it is worn.

[0027] Furthermore, the positioning mechanism 3 includes a support column 301, the support column 301 is fixedly installed on the top of the operating table 1, a placing plate 302 is fixedly installed on the top of the support column 301, a sleeve 303 is rotatably installed outside the support column 301, a worm gear 304 is fixedly installed on the top of the sleeve 303, a mounting frame 305 is fixedly installed on the top of the operating table 1, a driving motor 306 is fixedly installed on the top of the mounting frame 305, a worm 307 is fixedly installed on the output shaft of the driving motor 306, a movable frame 308 is fixedly installed outside the sleeve 303, a first connecting rod 309 is rotatably installed inside the movable frame 308, a limiting frame 310 is fixedly installed on the top of the operating table 1, a second connecting rod 311 is slidably installed inside the limiting frame 310, and a positioning plate 312 is fixedly installed outside the second connecting rod 311, which is convenient for fixing motor shafts of different sizes and specifications and avoiding the phenomenon that their positions change randomly during the processing.

[0028] Furthermore, the bottom of the sleeve 303 is rotatably installed inside the operating table 1, and the worm gear 304 is meshed with the worm 307, which is convenient for realizing the stable rotation of the sleeve 303 and avoiding the phenomenon that the sleeve 303 still rotates after the motor shaft is fixed.

[0029] Further, there are four sets of the first connecting rod 309, the limiting frame 310, the second connecting rod 311 and the positioning plate 312. The first connecting rod 309 is rotatably installed with the second connecting rod 311. The first connecting rod 309 is arranged in an "L" shape, which is convenient for clamping and positioning the motor shaft to be tapped, ensuring stable processing while reducing the phenomenon of the tap head breaking.

[0030] Embodiment 2: Please refer to Figure 6 , and in combination with Embodiment 1, it is further obtained that the auxiliary cooling mechanism 5 includes a liquid storage tank 501 that can store coolant. A liquid injection pipe 502 is fixedly installed on the top of the liquid storage tank 501. A liquid extraction pump 503 is fixedly installed outside the liquid storage tank 501.

[0032] In the actual operation process, when tapping different sizes and specifications of motor shafts, the motor shaft to be processed can be placed on the top of the placement plate 302. Subsequently, to ensure the stability during processing, the driving motor 306 can be turned on to make the worm 307 rotate, so that the meshing worm gear 304 rotates, thereby making the set movable frame 308 rotate, so that the four first connecting rods 309 rotate, pulling the second connecting rod 311. Under the limiting action of the limiting frame 310, the set second connecting rod 311 can slide centrally inside the limiting frame 310, so that the four positioning plates 312 move centrally, thereby clamping and positioning the placed motor shaft. After the clamping and positioning are completed, the driving motor 306 can be turned off to lock the clamping position and avoid the phenomenon that the motor shaft moves randomly during the processing. Subsequently, the tapping device 4 can be operated to tap the motor shaft. To avoid the phenomenon that the temperature of the processing position is too high, resulting in the deformation of the motor shaft or the damage of the tapping device 4, the liquid extraction pump 503 can be turned on. Under the action of the connecting pipe 504 for extracting and discharging liquid, the coolant inside the liquid storage tank 501 can be extracted and sprayed onto the processing position through the connecting nozzle 506 to achieve the cooling effect.
