Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly equipment, and in particular to a motor assembly positioning tool and a motor production turntable. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (also known as a stator winding) to generate a rotating magnetic field, which acts on a rotor (such as a squirrel-cage aluminum frame) to generate magneto-electrodynamic torque. A motor primarily consists of a stator and a rotor. The direction of force exerted on a current-carrying conductor in a magnetic field is related to the direction of the current and the magnetic flux lines (magnetic field). The motor's operating principle is that the magnetic field exerts a force on the current, causing the motor to rotate.

[0003] Currently, motor assembly on the market requires the stator, rotor, and end covers to be installed inside the casing. The stator wires need to pass through the end covers, so when press-fitting the stator, the end covers need to be placed next to the barrel. However, there is no structure to support the end covers, making automated production difficult. Summary of the Invention

[0004] The purpose of this technical solution is to provide a motor assembly positioning tool and a motor production turntable. The barrel and end cover are supported by a positioning seat and a placement frame, so that the barrel and end cover are close to each other, and there is no need to stretch the stator wiring too long, thereby solving the problem of difficulty in automated production of the original equipment and excessive stretching of the stator wiring.

[0005] The purpose of this technical solution is achieved in this way:

[0006] A motor assembly positioning tool is used to support a barrel and an end cover, comprising: a positioning seat, on which a positioning portion is protruding, and the positioning portion is used to fix the barrel; and a placement rack, which is arranged on the positioning seat and located beside the positioning portion, and is used to support the end cover; wherein, when the barrel is placed on the positioning seat and the end cover is placed on the placement rack, the end cover is located obliquely above the barrel.

[0007] Preferably, a through hole is provided at the center of the positioning portion.

[0008] Preferably, a positioning groove is provided on the positioning portion.

[0009] Preferably, a boss is formed around the bottom circumference of the positioning portion.

[0010] Preferably, the placement rack includes: a connecting column, which is plugged into the positioning seat; and a placement plate, which is arranged on the top end of the connecting column.

[0011] A motor production rotating tray comprises: a rotating tray; and a plurality of positioning fixtures, which are arranged on the rotating tray via a quick-release structure.

[0012] Preferably, the quick-release structure includes: a connecting member 1, which is arranged in an installation groove 1 opened on the rotating material disk; a connecting member 2, which is arranged in an installation groove 2 opened on the positioning seat; and a locking pin, which passes through the connecting member 2, the positioning seat, the rotating material disk and the connecting member 1 in sequence, and is used to fix the positioning seat on the rotating material disk.

[0013] Preferably, the positioning tool further includes a support block, which is arranged below the rotating material tray and below the corresponding positioning seat.

[0014] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0015] 1. The positioning tooling designed in this technical solution is adapted to the processing process of the barrel and the end cover. The end cover is placed at a higher position, just next to the top of the barrel. When the stator and the end cover are pressed onto the barrel, the movement distance of the end cover is saved, and the need to reserve too long stator wiring is also avoided. Excessive stator wiring will cause unnecessary trouble during the motor processing process.

[0016] 2. The quick-disassembly structure designed in this technical solution can realize the rapid installation and removal of the positioning seat on or from the rotating material tray, which is convenient for positioning tooling loading and processing to adapt to different models of motors.

DETAILED DESCRIPTION

[0025] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0026] The motor assembly equipment of the present application is used to install the stator, rotor and end cover 2 in the barrel 1 in sequence to form a complete motor. In the process of manufacturing the motor, it is necessary to first prepare the corresponding raw materials and store the raw materials on the corresponding storage trays, and then place the raw materials on a unified production line for processing and assembly. Specifically, the barrel 1 needs to be arrayed on the barrel 1 loading tray in the same direction, and then the end cover 2 needs to be passed through the stator wiring and then arrayed on the stator loading tray in the same direction, so that the stator and the end cover 2 are in a stacked state. The stacked state means that the end cover 2 is placed above the stator and the stator wiring passes through the through hole of the end cover 2. Finally, the rotor with the bearing is arrayed on the barrel 1 in the same direction. On the feeding tray, after the raw materials are prepared, the motor assembly equipment works to transfer and process the barrel 1, stator, rotor and end cover 2. The process is to use a robot to grab the barrel 1, stator, rotor and end cover 2 and place them on the feeding device, and then press-fit them in sequence to finally form a motor. It should be noted that in the process of loading the stator and end cover 2 and pressing the end cover 2, the plane rotation of the end cover 2 will be involved. When the end cover 2 is rotated in the plane, it is necessary to ensure that the wiring of the stator is always located in the through hole of the end cover 2. In order to achieve this purpose, the present application has designed a positioning tool to facilitate the loading of the barrel 1 and the end cover 2, and to ensure that the end cover 2 will not be too far away from the barrel 1 to cause processing difficulties and other problems.

[0027] like Figure 1-4 As shown, a motor assembly positioning tool is used to carry the barrel 1 and the end cover 2, including a positioning seat 3, a placement rack 5 and a support block 18. The positioning seat 3 is used to load the barrel 1, and the placement rack 5 is used to load the end cover 2. The height of the placement rack 5 is adapted to the height of the barrel 1. The placement rack 5 is located next to the barrel 1. When the barrel 1 is placed on the positioning seat 3 and the end cover 2 is placed on the placement rack 5, the end cover 2 is just located next to the barrel 1, in preparation for the subsequent retraction of the distance between the stator and the end cover 2, so that the wiring of the stator will not be stretched longer due to the distance from the end cover 2.

[0028] Furthermore, in order to increase the stability of the placement of the barrel 1, we have protruded a positioning portion 4 on the positioning seat 3, and the positioning portion 4 is adapted to the recess at the bottom of the barrel 1. At the same time, we have opened a positioning groove 7 on the positioning portion 4, and added a positioning block 71 in the groove at the bottom of the barrel 1. When the barrel 1 is placed on the positioning seat 3, the positioning portion 4 is placed in the groove, and the positioning block 71 is placed in the positioning groove 7, so that the barrel 1 will not rotate circumferentially on the positioning portion 4. At the same time, we have also designed a boss 8 on the peripheral side of the bottom of the positioning portion 4, and the boss 8 is adapted to the shape of the bottom of the barrel 1, further increasing the stability of the placement of the barrel 1.

[0029] Furthermore, in subsequent processing, the rotor needs to be press-fitted, and the central axis of the rotor will pass through the barrel 1. For this purpose, a through hole 6 is opened at the center of the positioning part 4 to facilitate the insertion of the central axis of the rotor.

[0030] like Figure 2 and Figure 3 As shown, the placement rack 5 is composed of a connecting column 9 and a placement plate 10. The lower end of the connecting column 9 is inserted into the positioning seat 3, and the upper end is provided with a placement plate 10. The placement rack 5 can be adapted to different models of barrels 1 by changing the length of the connecting column 9.

[0031] like Figure 5-7 As shown, a motor production rotating tray 11 includes a rotating tray 11 and a plurality of positioning tools. The positioning tools are evenly arranged on the rotating tray 11, and the positioning tools are arranged on the rotating tray 11 through a quick-release structure 12.

[0032] Specifically, the quick-release structure 12 includes a connector 13, a connector 2 15 and a locking pin 17. The connector 13 can be installed in the installation groove 14 opened on the rotating material disk 11 by bolts, and the connector 2 15 can be installed in the installation groove 2 16 opened on the positioning seat 3 by bolts. Both the connector 13 and the connector 2 15 are provided with a cylindrical groove inside, and an "I"-shaped through groove is also provided at the bottom of the cylindrical groove. Two groups of snap-fit pins are protruding from the locking pin 17, and the snap-fit pins can pass through the through groove and enter the cylindrical groove. When the locking pin 17 is rotated, the snap-fit pin will be locked in the cylindrical groove. Therefore, when the locking pin 17 passes through the connector 2 15, the positioning seat 3, the rotating material disk 11 and the connector 1 13 in sequence, and after the locking pin 17 is rotated, the positioning seat 3 can be fixed on the rotating material disk 11.

[0033] Furthermore, the positioning tooling also includes a support block 18, which is arranged below the rotating disc 11, and the support block 18 is arranged below the corresponding positioning seat 3. The support block 18 is used to cooperate with the subsequent device with a pressing function to work. The support block 18 can increase the pressure area of the rotating disc 11, reduce the pressure on the rotating disc 11, and increase the practical life of the rotating disc 11. At the same time, it supports the rotating disc 11 so that the stator, rotor and end cover 2 can obtain a better pressing effect.
