Description

Technical Field

[0001] The utility model relates to the field of shaft processing, in particular to a shaft processing device used for the research and development of stepper motor components. Background Art

[0002] At present, the Chinese utility model with the announcement number CN215545110U discloses a drilling device for motor shaft processing, comprising a base, support plates are provided at both ends of the base, and drilling assemblies arranged coaxially are provided on the side walls of the two groups of support plates in the facing directions of each group of support plates. A clamping assembly is provided in the middle of the base between the two groups of drilling assemblies. The utility model has a simple structure and is easy to operate. By drilling holes synchronously at both ends of the motor shaft, the center holes at both ends of the motor shaft are located at the same axial position, which makes processing convenient and efficient.

[0003] Although the existing shaft processing device can fix the shaft by clamping the assembly, there are still other problems during use, such as the inability to adjust the height of the shaft. The position of the shaft is fixed after it is fixed. Due to the different volumes of shafts of different specifications, the center drilling positions of shafts of different specifications will deviate after they are fixed. If the height cannot be adjusted after the shaft is fixed, only shafts of a single specification can be processed, which has poor applicability and does not have dust collection and filtration functions. Dust will be generated when the drill bit contacts the shaft during the rotation and propulsion process. After the dust is formed, it will fly outward with the wind. If the flying dust is inhaled by people around, it will cause damage to the respiratory tract. The practicality is low. In order to solve the above problems, we propose a shaft processing device for the research and development of stepper motor components. Utility Model Content

[0008] By adopting the above technical solution, through the arrangement of the second motor, the mounting seat and the drill bit, the drill bit can be driven to drill a hole in the side end of the shaft after the second motor is started.

[0011] The utility model is further configured as follows: a protective cover is bolted to one side of the fixing frame.

[0012] By adopting the above technical solution and providing the protective cover, the first motor can be protected to prevent the first motor from being damaged by collision with foreign objects.

[0013] The utility model is further configured as follows: a limiting rod is symmetrically welded to the bottom of the placement seat, and the other end of the limiting rod passes through and extends to the interior of the mounting frame.

[0014] By adopting the above technical solution, the placement seat can be limited by setting the limiting rod to prevent the placement seat from rotating during the process of moving up and down.

[0015] The utility model is further configured as follows: a turning handle is welded on the bottom end of the threaded rod.

[0016] By adopting the above technical solution, the setting of the turning handle can facilitate personnel to rotate the threaded rod.

[0017] The utility model is further configured as follows: the top and the bottom of the activated carbon filter are both clamped with a clamping seat, and the other side of the clamping seat is bolted to the inside of the base.

[0018] By adopting the above technical solution, the activated carbon filter can be limited by the setting of the holder to prevent the activated carbon filter from shifting due to shaking and wind guidance.

[0019] The utility model is further configured as follows: two through slots are provided on the top of the fixing frame, and two dustproof nets are bolted to the top of the fixing frame.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. The utility model places the shaft into the placement seat first. After the shaft is placed, the cylinder is started to drive the limit plate to move downward. When the limit plate moves downward, it drives the rubber pad to press the shaft. After the shaft is positioned, the handle is held by hand to drive the threaded rod to rotate. When the threaded rod rotates, it drives the placement seat upward through the cooperation of the bearing and the limit rod. When the placement seat moves upward, it drives the shaft to make its center point flush with the drill bit. The height of the shaft can be adjusted. The operation is simple and convenient, and it is suitable for processing shafts of different specifications and has good flexibility.

[0025] 2. The utility model starts the exhaust fan, which will discharge the air inside the base from the exhaust port after startup. When negative pressure is generated in the base due to the air discharge, the dust-containing gas in the fixed frame will be sucked in through the through hole under the negative pressure state. The dust-containing gas will pass through the activated carbon filter when it is sucked into the base and discharged outside. The activated carbon filter will adsorb and intercept impurities in the gas, and can have dust collection and filtration functions, which can prevent flying dust from being inhaled by the human body and causing damage to the human body. It can also improve the surrounding environment, reduce the burden of cleaning, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
