Description

Technical Field

[0001] The utility model relates to the technical field of motor housing processing, in particular to a positioning auxiliary tool for motor housing processing. Background Art

[0002] An electric motor is an electromagnetic device that converts electrical energy into mechanical energy. Electric motors, commonly known as "motors," operate according to the law of electromagnetic induction and can be categorized as either motors or generators. A motor converts electrical energy into mechanical energy, while a generator converts mechanical energy into electrical energy. Electric motors play a vital role in a wide range of applications, from household appliances to industrial equipment, from electric vehicles to wind power systems.

[0003] During the production process of the motor, its housing needs to be processed. When clamping some motor housings, because the inner wall of the housing is round, some positioning tooling cannot effectively clamp the motor housing during processing, so that it will not rotate during processing. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a positioning auxiliary tool for machining a motor housing.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The positioning auxiliary tooling includes a mounting plate, which is mounted on a positioning tooling frame. A positioning arc plate is fixedly connected to one side of the mounting plate. A limiting clamping plate is provided at the bottom of the mounting plate. The motor housing body is sleeved on the outer wall of the positioning arc plate. The outer surface of the positioning arc plate is in contact with the inner wall of the motor housing body, and the limiting clamping plate is against the bottom of the motor housing body.

[0008] In addition, a preferred structure is that second mounting holes are symmetrically opened on the mounting plate, and second fixing components are installed at the second mounting holes.

[0009] In addition, a preferred structure is that mounting grooves are symmetrically provided on both side walls of the top column of the positioning fixture, mounting plates are installed at the mounting grooves, and through holes are symmetrically provided at the mounting grooves, through which the second fixing component can pass.

[0010] In addition, a preferred structure is that a bolt hole is opened in the middle of the side wall of one end of the top column of the positioning fixture, a first fixing component is screwed onto the bolt hole, and positioning holes are opened symmetrically on both sides of the bolt hole.

[0011] In addition, a preferred structure is that the limit baffle is installed at the end of the positioning fixture frame where the bolt hole is opened.

[0012] In addition, a preferred structure is that a first mounting hole is opened in the middle of the limit baffle, a first fixing component is installed at the first mounting hole, and positioning columns are symmetrically provided on the side wall surface of one side of the limit baffle and on both sides of the first mounting hole.

[0013] The beneficial effects of the present invention are as follows: the positioning auxiliary tooling provided in the present invention is used to sleeve the motor housing body, so that when the motor housing body with a circular inner wall is clamped, the positioning arc plate can effectively fit the inner wall of the motor housing body, so that the motor housing body will not rock back and forth after clamping, and the limiting clamping plate provided at the bottom will press against the bottom of the motor housing body, thereby preventing the motor housing body from rocking during processing, and the provided limiting baffle can prevent the motor housing body from rocking left and right, and the positioning auxiliary tooling can be replaced with different sizes according to different motor housings, so that the entire positioning tooling has better versatility while ensuring firm clamping.
