Description

Technical Field

[0001] This utility model relates to the field of motor assembly automation technology, and in particular to an automatic magnetic sheet insertion device for permanent magnet motors. Background Technology

[0002] Permanent magnet motors are widely used in industries, new energy vehicles, and home appliances due to their high efficiency, high power density, and excellent speed regulation performance. One of the core components of a permanent magnet motor is the magnetic sheet, and its installation accuracy directly affects the motor's performance and reliability.

[0003] Currently, there are various methods for installing permanent magnet motor magnetic sheets. Surface-mounted installations commonly use non-woven tape binding, where the tape is wrapped around the magnet and coated with epoxy resin. This method offers high reliability but is prone to rotor rubbing due to thermal expansion and contraction. Adhesive bonding uses high-performance glue for fixation, which is simple to operate but requires careful control of curing time. Screws are used to fix the iron core and magnets by drilling holes and locking them in place. This method is simple but prone to large vibrations due to processing deviations. Embedded installations often use embedded magnets, where the magnets are installed into pre-punched magnet slots in the rotor laminations to ensure magnetic circuit symmetry. Alternatively, magnets can be pressed into the slots using interference fits or fixed with magnet sleeves to enhance stability.

[0004] The above-mentioned existing technical solutions have the following drawbacks: the magnetic sheet is prone to displacement during insertion, resulting in improper installation; and it is difficult to ensure positional consistency when multiple magnetic sheets are installed simultaneously. Utility Model Content

[0005] The purpose of this invention is to provide an automatic magnetic sheet insertion device for permanent magnet motors to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An automatic magnetic sheet insertion device for a permanent magnet motor includes a worktable and further includes:

[0008] A chuck is fixedly installed on the top of the workbench, a wrench is rotatably installed on the side wall of the chuck, and a vertical plate is fixedly installed on the proximal end of the jaws of the chuck.

[0009] A lifting device is provided, which is located in the central circular hole of the chuck body, and is used to lift the magnetic sheet.

[0010] A fixing device is provided, which is located on the top of the workbench and the top of the fixing device is located above the lifting device. The fixing device is used to fix the permanent magnet motor on which the magnetic sheet to be installed is located.

[0011] By adopting the above technical solution, the vertical plate and the lifting device form multiple mounting slots. Magnetic sheets are placed in the mounting slots. The wrench is turned so that the vertical plate presses against the magnetic sheets. Then, the permanent magnet motor with the magnetic sheets to be installed is placed on the lifting device. The permanent magnet motor is pressed against the top of the lifting device by the fixing device. Then, the lifting device is started to send the magnetic sheets into the permanent magnet motor.

[0012] In a further embodiment, the lifting device includes:

[0013] The cylinder includes a fixed part and a movable part. The movable part of the cylinder is located at the top of the cylinder body. The fixed part of the cylinder is fixedly connected to the inner wall of the central circular hole of the chuck body.

[0014] The tooling is a cylinder, the bottom of which is fixedly connected to the top of the movable part of the cylinder, and multiple columns are evenly distributed at equal intervals around the top periphery of the cylinder, and the multiple columns are fixedly installed on the top of the cylinder.

[0015] In a further embodiment, the fixing device includes a first vertical rod and a second vertical rod, which are symmetrically arranged at both ends of the diameter extension line of the chuck body. The second vertical rod is located at the right end of the first vertical rod. A crossbeam is rotatably mounted on the top of the first vertical rod. A rearward semi-circular groove is provided on the front side of the right end of the crossbeam. A locking ring is sleeved on the top of the second vertical rod. The diameter of the locking ring is larger than the diameter of the semi-circular groove.

[0016] In a further embodiment, the top end of the second vertical rod is provided with threads, the inner wall of the locking ring is provided with threads, and the locking ring is screwed onto the top end of the second vertical rod.

[0017] In a further embodiment, the centrifugal end of the column is provided with mutually close clearance grooves on both sides.

[0018] In a further embodiment, a handle is fixedly mounted on the outer wall of the locking ring.

[0019] By adopting the above technical solution, rotating the wrench causes the chuck to move centripetally, forming a receiving groove between adjacent columns and vertical plates. Then, the magnetic sheet is placed into the receiving groove, and the wrench is rotated again to make the vertical plate press against the magnetic sheet. The permanent magnet motor with the magnetic sheet to be installed is then placed on the chuck, ensuring that the center of the permanent magnet motor is aligned with the lifting device. The crossbeam is rotated toward the second vertical rod so that the semi-circular groove at the right end of the crossbeam is aligned with the top of the second vertical rod. Then, the locking ring is turned down by the handle to press the crossbeam down, making the permanent magnet motor firmly fixed. The cylinder is then started, and the moving part of the cylinder drives the fixture to rise, so that the magnetic sheet is smoothly inserted into the predetermined position along the inner wall of the permanent magnet motor. After the magnetic sheet is installed in place, the locking ring is rotated in the opposite direction to make the crossbeam move away from the second vertical rod 62. The installed permanent magnet motor is then removed, and the cylinder is retracted and reset, and the fixture is lowered and reset, ready for the next cycle.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. The vertical plate and lifting device form multiple mounting slots. Magnetic sheets are placed in the slots. The wrench is turned to make the vertical plate press against the magnetic sheets. The permanent magnet motor to be installed with magnetic sheets is then placed on the lifting device. The permanent magnet motor is fixed to the top of the lifting device by the fixing device. Then the lifting device is started to send the magnetic sheets into the permanent magnet motor. This can prevent the magnetic sheets from shifting during the insertion process and allow multiple magnetic sheets to be installed into the permanent magnet motor simultaneously.

[0022] 2. By rotating the wrench, the chuck moves centripetally, forming receiving slots between adjacent columns and vertical plates. The magnetic sheet is then placed into the receiving slot. The wrench is rotated again, causing the vertical plate to press against the magnetic sheet. The permanent magnet motor with the magnetic sheet to be installed is then placed on the chuck, ensuring the center of the permanent magnet motor is aligned with the lifting device. The crossbeam is rotated towards the second vertical rod, aligning the semi-circular groove at the right end of the crossbeam with the top of the second vertical rod. The locking ring is then tightened downwards by the handle to press the crossbeam firmly, securing the permanent magnet motor. The cylinder is then activated, causing the moving part of the cylinder to lift the fixture, allowing the magnetic sheet to be smoothly inserted into the predetermined position along the inner wall of the permanent magnet motor. After the magnetic sheet is in place, the locking ring is rotated in the opposite direction, causing the crossbeam to move away from the second vertical rod. The installed permanent magnet motor is then removed. The cylinder is then retracted to reset, and the fixture descends to reset. This process allows multiple magnetic sheets to be automatically inserted into the permanent magnet motor with the magnetic sheet to be installed. Attached Figure Description
