Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a motor rotor assembly tool. Background Art

[0002] The motor rotor is the rotating part of the motor. The motor consists of two parts: the rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is divided into the motor rotor and the generator rotor. The motor rotor is divided into two types: the inner rotor rotation mode and the outer rotor rotation mode. The inner rotor rotation mode is that the core in the middle of the motor is the rotating body, outputting torque (referring to the motor) or receiving energy (referring to the generator). The outer rotor rotation mode is that the outer body of the motor is the rotating body.

[0003] In the current processing of new energy vehicle motors, the rotor assembly is installed after the motor front end cover bearing is assembled. However, this motor rotor assembly method leaves the bearing unsupported, and the rotor mass is relatively large, which can easily lead to stress damage to the bearing, making it impossible to guarantee the quality of the processed motor. Moreover, this processing method places high technical requirements on the processing operators, resulting in low processing efficiency. Utility Model Content

[0004] The utility model aims to provide a motor rotor assembly tool to solve the problem that the bearing is easily damaged during motor processing.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a motor rotor assembly tool, comprising a support frame and a support mechanism, the top of the support frame is fixedly connected with two mutually parallel slide rails, the two slide rails are slidably connected with the same horizontal tooling plate, the slide rails are used to drive the tooling plate to move horizontally and stop moving, and the tooling plate is provided with a plurality of through holes;

[0006] The support mechanism comprises a cylinder, which is fixedly connected to the support frame. The output shaft of the cylinder is vertically upward and is fixedly connected with a fixing device for fixing the inner diameter of the support bearing.

[0007] The working principle of the utility model is as follows: when assembling the motor rotor, the stator assembly of the motor is placed on the tooling plate, and the stator assembly is located directly above the through hole, and then the tooling plate is driven to move horizontally on the support frame through the operation of the slide rail. When the tooling plate moves horizontally, it drives the stator assembly to move synchronously. When the through hole moves to directly above the fixed tooling, the slide rail stops running. At this time, the horizontal plate stops moving, and the stator assembly is located directly above the through hole and the fixed tooling. The cylinder is started, and the output shaft of the cylinder begins to extend when the cylinder is running. Since the fixed tooling is fixed on the output shaft of the cylinder, the output shaft of the cylinder drives the fixed tooling to move vertically upward when it extends upward. The fixed tooling passes through the through hole upward until it contacts the bearing in the stator assembly, stabilizes the bearing, and the cylinder stops running. At this time, the rotor is placed in the stator assembly and introduced into the stator assembly. After the installation is completed, the cylinder is reversed to shorten the output shaft of the cylinder. When the output shaft of the cylinder shortens, the fixed tooling is pulled downward to exit the stator assembly and the through hole. By repeating the above steps, the rotor can be installed on the stator assembly continuously.

[0008] The beneficial effects of the utility model are as follows: the scheme drives the tooling plate on which the stator assembly is placed to move horizontally through the slide rail, and then drives the stator assembly to move to just above the fixed tooling, and then drives the fixed tooling to move and contact the bearing in the stator assembly through the cylinder to fix it to prevent it from shifting and skewing, and then puts the rotor in to install the rotor, which can effectively avoid the problem of bearing skewing, resulting in uneven force, force damage, or unqualified rotor installation due to bearing skewing when installing the rotor.

[0009] Furthermore, the support frame is fixedly connected with four rectangularly distributed limiting columns, and the fixed fixture is provided with four limiting holes, which are respectively slidably sleeved on the four limiting columns. The purpose is to reduce the possibility of the fixed fixture being skewed during the lifting process through this arrangement, thereby avoiding the occurrence of the bearing being skewed due to the skew of the fixed fixture.

[0010] Furthermore, each slide rail includes a track, a surface of which is provided with a groove, the length of the groove being the same as the length of the track, and a plurality of rollers are rotatably connected in the groove along its length direction, and the rollers are used to drive the tooling plate to move horizontally through friction when rotating.

[0011] Furthermore, the tooling plate is provided with a plurality of positioning grooves, the positioning grooves corresponding to the through holes one by one, and the positioning grooves are used to limit the placement position of the stator assembly when the stator assembly is placed so as to align the stator assembly with the through holes.

[0013] Figure 2 It is a left side view of the motor rotor assembly tool of the utility model. DETAILED DESCRIPTION

[0014] The following is further described in detail through specific implementation methods:

[0015] The reference numerals in the drawings of the specification include: stator assembly 1, rotor 2, track 3, roller 4, tooling plate 5, support frame 6, cylinder 7, fixing tool 8, and limit column 9.

[0016] The embodiment is basically as shown in the attached Figure 1 and attached Figure 2 As shown:

[0017] The motor rotor assembly tooling includes a support frame 6 and a support mechanism. Two parallel slide rails are fixedly connected to the top of the support frame 6. The same horizontal tooling plate 5 is buckled on the two slide rails. Each slide rail includes a track 3. The surface of the track 3 is provided with a groove. The length of the groove is the same as the length of the track 3. A number of rollers 4 are rotatably connected in the groove along its length direction. The rollers 4 are used to drive the tooling plate 5 to move horizontally through friction when rotating. The tooling plate 5 is evenly spaced along its length direction. A plurality of positioning grooves are provided on the tooling plate 5. The positioning grooves correspond to the through holes one by one. The positioning grooves are used to limit the placement position of the stator assembly 1 when placing the stator assembly 1 so that it is aligned with the through holes.

[0018] The support mechanism includes a cylinder 7, which is fixedly connected to the support frame 6. The output shaft of the cylinder 7 is vertically upward and fixedly connected to a plate-shaped fixing fixture 8. The upper surface of the fixing fixture 8 is provided with a limit groove, and the limit groove has the same shape and size as the cross section of the bearing. Four rectangular limit columns 9 are fixedly connected to the support frame 6, and the fixing fixture 8 is provided with four limit holes, which are respectively slidably sleeved on the four limit columns 9.

[0019] The specific implementation process is as follows:

[0020] When assembling the motor rotor 2, the stator assembly 1 of the motor is placed on the tooling plate 5. The positioning groove on the tooling plate 5 defines the placement position of the stator assembly 1 to ensure that its position is accurate and the stator assembly 1 is located directly above the through hole. Then, the roller 4 during the operation of the slide rail drives the tooling plate 5 to move horizontally on the support frame 6. When the tooling plate 5 moves horizontally, it drives the stator assembly 1 to move synchronously. When the through hole moves to directly above the fixed tooling 8, the slide rail stops running. At this time, the horizontal plate stops moving. The stator assembly 1 is located directly above the through hole and the fixed tooling 8. The cylinder 7 is started. When the cylinder 7 is running, the output shaft of the cylinder 7 begins to extend. Since the fixed tooling 8 is fixed on the output shaft of the cylinder 7, the output shaft of the cylinder 7 extends upward, driving the fixed tooling 8 to move vertically upward. At this time, the fixed tooling 8 passes upward through the through hole until it contacts the bearing in the stator assembly 1 to stabilize the bearing, and the cylinder 7 stops running. At this time, put the rotor 2 into the stator assembly 1 and guide it into the stator assembly 1. After the installation is completed, run the cylinder 7 in reverse, and the output shaft of the cylinder 7 is shortened. When the output shaft of the cylinder 7 is shortened, pull the fixing tool 8 downward to exit the stator assembly 1 and the through hole. Repeat the above steps to continuously install the rotor 2 on the stator assembly 1.
