Description

Technical Field

[0001] This utility model belongs to the technical field of grinding equipment, and specifically relates to a grinding fixture for a brushless motor housing. Background Technology

[0002] A brushless motor consists of a motor body and a driver, and is a typical mechatronics product.

[0003] Currently, brushless motor housings require grinding during processing to remove surface imperfections, burrs, or scratches, resulting in a smooth surface. Traditional grinding methods primarily involve manual or machine tool grinding. Manual grinding is inefficient and labor-intensive. While machine tool grinding can reduce labor and increase grinding speed, it can only grind the outer or inner surface of the housing, not both simultaneously, thus limiting grinding efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a grinding fixture for brushless motor housings, which has the advantages of high grinding efficiency and applicability to different thicknesses.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a grinding fixture for a brushless motor housing, comprising a base, a placement platform rotatably connected to the top of the base via a rotating shaft, a connecting block provided on the top of the base, an installation groove formed on the top of the connecting block, an installation block slidably connected inside the installation groove, a drive motor embedded in the center of the installation block and the top of the connecting block, a bracket fixedly connected to the bottom of the connecting block and the bottom of the installation block, a rotating shaft fixedly connected to the output end of the drive motor rotatably inside the bracket, a grinding roller fixedly sleeved on the surface of the rotating shaft, an adjusting bolt threaded to one end of the connecting block, and one end of the adjusting bolt penetrating into the interior of the installation groove and rotatably connected to the installation block.

[0006] The above technical solution employs the following: A mounting groove is designed on the connecting block, and a mounting block is designed inside the mounting groove. Both the mounting block and the bottom of the connecting block are designed with grinding rollers. The shell wall of the brushless motor housing can be placed between the two grinding rollers. When the drive motor is started, the outer and inner walls of the brushless motor housing can be ground simultaneously, improving grinding efficiency. An adjusting bolt is threaded onto the connecting block, with one end penetrating into the mounting groove and rotatably connected to the mounting block. When the adjusting bolt is rotated, the mounting block moves within the mounting groove under the action of the sliding guide rail and sliding guide groove, thereby adjusting the distance between the grinding rollers on the mounting block and the grinding rollers on the connecting block. This allows it to be used for different shell wall thicknesses of brushless motor housings, improving applicability.

[0007] The present invention is further configured such that a sleeve is fixedly connected to the top of the base, a support column is slidably connected inside the sleeve, and a connecting seat that is slidably connected to the top of the support column is fixedly connected to the connecting block.

[0008] The above technical solution allows the sleeve to slide and limit the support column, and the support column is fixed together with the connecting seat, thus supporting and fixing the connecting seat, thereby achieving the purpose of supporting and fixing the connecting block.

[0009] The present invention is further configured such that one end of the connecting seat is threadedly connected to a limit bolt, the limit bolt is rotatably connected to the connecting block through a bearing, and a hydraulic cylinder is assembled between the sleeve and the support column.

[0010] The above technical solution is adopted: when the limit bolt is turned, the limit bolt moves into the connecting seat and contacts the connecting block, so as to lock the connecting block. This can limit the connecting block inside the connecting seat. The hydraulic cylinder is designed inside the sleeve. When the hydraulic cylinder is started, the output end of the hydraulic cylinder can drive the support column to adjust the height position of the sleeve.

[0011] The present invention is further configured such that the top of the base is provided with equidistant limiting grooves, the top of the limiting grooves is provided with a limiting frame, and the inside of the limiting frame is provided with a limiting roller that rotates through a rotating shaft.

[0012] The above technical solution is adopted: the limiting frame is used to install the limiting roller, and the surface of the limiting roller contacts the outer surface of the brushless motor housing to form a limit on the brushless motor housing.

[0013] The present invention is further configured such that a limiting block is slidably connected inside the limiting groove and fixedly connected to the limiting frame, and a stepper motor fixedly connected to the limiting roller shaft is mounted on the top of the limiting block.

[0014] The above technical solution is adopted: the limiting block is used to fix the limiting frame, and the output end of the stepper motor is fixedly connected to the rotating shaft of the limiting roller, which can drive the limiting roller to rotate, thereby causing the brushless motor housing to rotate on the worktable.

[0015] The present invention is further configured such that one end of the limiting block is connected to an adjusting screw, the surface of the adjusting screw is threadedly connected to the base, and one end of the adjusting screw extends through to the outside of the base.

[0016] The above technical solution allows the limiting block to move inside the limiting groove when the adjusting screw is rotated, thereby adjusting the position of the limiting roller and making it suitable for brushless motor housings of different sizes.

[0017] The present invention is further configured such that a sliding guide groove is provided inside the mounting groove, and a sliding guide rail that is slidably connected to the sliding guide groove is fitted on the surface of the mounting block.

[0018] The above technical solution uses a sliding guide groove and a sliding guide rail in combination to limit the sliding movement of the mounting block within the mounting groove.

[0019] In summary, this utility model has the following beneficial effects: 1. This application has a mounting groove designed on the connecting block, and a mounting block designed inside the mounting groove. Both the mounting block and the bottom of the connecting block are designed with grinding rollers. The shell wall of the brushless motor housing can be placed between the two grinding rollers. When the drive motor is started, the outer and inner walls of the brushless motor housing can be ground at the same time, thereby improving grinding efficiency. 2. This application has an adjusting bolt threaded onto the connecting block, with one end of the adjusting bolt penetrating into the interior of the mounting groove and rotatably connected to the mounting block. When the adjusting bolt is rotated, the mounting block can be moved inside the mounting groove under the action of the sliding guide rail and the sliding guide groove, thereby achieving the purpose of adjusting the distance between the grinding roller on the mounting block and the grinding roller on the connecting block, so that it can be applied to different shell wall thicknesses of brushless motor housings and improve applicability.
