Description

Technical Field

[0001] This utility model belongs to the field of motor testing technology, specifically relating to a quick clamping device for motor no-load testing. Background Technology

[0002] The current industry standard for motor testing involves locking the motor's feet or flange end caps onto the test bench using tooling, which has the following drawbacks:

[0003] A. The test bench is large and heavy, making it difficult to fit effectively with the production line. It is necessary to transfer the assembled motor to the test area, and after the test is completed, the motor needs to be transferred back to the production line to continue other processes. The workload of the transfer is large.

[0004] B. Low production efficiency; the motor is locked and fixed with bolts, making disassembly and assembly complicated.

[0005] Considering production efficiency, it was not possible to transfer all the motors from the production line and fix them on the test bench.

[0006] The current production, installation and testing of new energy vehicle motors are mostly done on assembly lines. In the no-load testing process, the motor is placed directly on the tooling plate without any fixing. As the speed increases, there is a risk of stalling and running away during the high-speed rotation of the motor.

[0007] Therefore, it is necessary to design a clamping device suitable for quickly fixing motors on an assembly line and facilitating motor testing. Utility Model Content

[0008] The purpose of this utility model is to provide a quick clamping device for no-load testing of motors.

[0009] To achieve the above objectives, the technical solution specifically provided by this utility model is as follows:

[0010] A quick clamping device for no-load testing of a motor includes a motor clamping mechanism and a first motor positioning mechanism disposed on a tooling plate of a production line. The motor clamping mechanism includes a pair of parallel sliding tooling plates and a pair of support members fixedly disposed on the profile of the production line. The support members are respectively disposed on both sides of the tooling plate of the production line, and the sliding tooling plate is disposed between the two support members. The support members are provided with driving members for driving the two sliding tooling plates away from or towards each other and guiding components for guiding the sliding tooling plates to slide along a direction perpendicular to the movement direction of the production line. A second motor positioning mechanism is disposed on the sliding tooling plate.

[0011] By adopting the above technical solution, rapid clamping and fixing of the motor under test can be achieved on the production line. Specifically, the motor under test is initially fixed by the first motor positioning mechanism on the production line tooling plate; when the motor moves between the two support members, the two sliding tooling plates are driven to move closer together by the driving component, and the second motor positioning mechanism on the sliding tooling plate can further position the motor, making the motor under test securely fixed and reducing test safety hazards. The motor no-load test rapid clamping device of this utility model has the advantages of achieving efficient and secure fixing of the motor and a high safety factor.

[0012] Furthermore, the support member is a fixed tooling plate, and the two fixed tooling plates are parallel to each other. Using the fixed tooling plate as the support member makes it easy to install components such as drive components, and it is also easy to fix and install it onto the profiles of the production line by means of bolt connection, welding or other methods.

[0013] Furthermore, the guiding assembly includes a fixed linear guide rail, which passes through two sliding fixture plates and is fixed at both ends to the fixed fixture plates. On the one hand, the fixed linear guide rail allows the two fixed fixture plates to remain relatively parallel, increasing the reliability of the support component; on the other hand, the linear guide rail can guide the sliding fixture plates to move smoothly, facilitating the positioning and fixing of the motor under test.

[0014] Furthermore, the guiding assembly also includes a movable linear guide rail mounted on the fixed fixture plate via a linear bearing, the end of which is connected to the sliding fixture plate. The combined use of the movable and fixed linear guide rails provides better performance, reducing the likelihood of skewing or offset during the movement of the sliding fixture plate.

[0015] Furthermore, the driving component is a pneumatic cylinder or a hydraulic cylinder whose movable end is connected to the sliding fixture plate. Selecting a pneumatic cylinder or hydraulic cylinder with an appropriate stroke can realize automatic control of the forward and backward movement of the sliding fixture plate, achieving efficient clamping and fixation of the motor.

[0016] Furthermore, the first motor positioning mechanism includes a pair of positioning blocks fixed to the tooling plate of the production line, and each positioning block has a positioning groove for the motor to be tested to be inserted into. The positioning blocks restrict the axial displacement of the motor, achieving reliable axial positioning of the motor.

[0017] Furthermore, the second motor positioning mechanism includes a positioning fixture plate fixedly mounted on the sliding fixture plate, the positioning fixture plate being provided with a plurality of positioning pins for inserting into the through holes of the motor end cover to be tested. The positioning pins are inserted into the through holes of the motor end cover, achieving circumferential positioning and fixation of the motor.

[0018] Furthermore, it also includes a conveyor belt stop, which enables the motor to be positioned in the direction of movement of the conveyor belt.

[0019] Furthermore, it also includes a lifting device located below the tooling plate on the production line. As needed, the lifting device can be used to lift and raise the tooling plate on the production line to achieve positioning of the motor in the height direction. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the present application will be further described in detail below with reference to the accompanying drawings.

[0026] A quick clamping device for no-load testing of motors, referring to Figure 1 and Figure 2 The assembly includes a pair of fixed fixture plates 4, a pair of sliding fixture plates 3, and a pair of positioning blocks 8, which are directly installed on the production line. The positioning blocks 8 are fixedly mounted on the top surface of the production line fixture plate 1, and their top surface has trapezoidal positioning grooves 9 for the motor to be tested to engage. The production line fixture plate 1 is slidably assembled onto two parallel production line profiles 2, and can move along the production line profiles 2. The length direction of the positioning blocks 8 is consistent with the length direction of the production line profiles 2. Placing the motor to be tested on the two positioning blocks 8, so that the motor engages in the positioning grooves 9, achieves preliminary positioning and fixation of the motor. In other embodiments, positioning blocks 8 and positioning grooves 9 of other shapes can also be selected, and the number of positioning blocks 8 can be increased or decreased as needed.

[0027] Reference Figure 1 and Figure 2Two fixed fixture plates 4 are vertically mounted and fixed to the side of the profile 2 on the production line by bolts. The two fixed fixture plates 4 are located on both sides of the production line fixture plate 1. Two sliding fixture plates 3 are arranged parallel between the two fixed fixture plates 4, and a clamping space is formed between the two sliding fixture plates 3 for clamping and fixing the motor under test.

[0028] Reference Figure 1 and Figure 2 A fixed linear guide rail 5 is fixedly connected between the opposite apex angles of two fixed fixture plates 4. The two fixed linear guide rails 5 are parallel to each other and perpendicular to the fixed fixture plates 4. The fixed linear guide rail 5 passes through the sliding fixture plate 3, and the sliding fixture plate 3 is assembled to the fixed linear guide rail 5 via bearings. Each fixed fixture plate 4 is provided with a pair of movable linear guide rails 6 via linear bearings. The ends of the movable linear guide rails 6 are connected to the lower apex angle of the sliding fixture plate 3. This allows the sliding fixture plate 3 to slide smoothly along the length direction of the fixed linear guide rail 5. At the same time, the fixed fixture plate 4, the sliding fixture plate 3, the fixed linear guide rail 5, and the movable linear guide rail 6 together constitute the main body of the quick clamping device with good stability.

[0029] Reference Figure 1 and Figure 2 A driving component 7 is provided on the side of the fixed fixture plate 4 opposite to the sliding fixture plate 3. In this embodiment, the driving component 7 is a cylinder. The movable end of the cylinder passes through the fixed fixture plate 4 and is connected to the sliding fixture plate 3. The cylinder generates pushing and pulling force to drive the sliding fixture plate 3 to move, thereby causing the two sliding fixture plates 3 to move closer or further apart to clamp or release the motor. In this embodiment, driving components 7 are provided on both fixed fixture plates 4, which can independently drive the two sliding fixture plates 3 to move.

[0030] Reference Figure 1 and Figure 2 A positioning fixture plate 10 is fixedly mounted on the side of the sliding fixture plate 3 facing the other sliding fixture plate 3. One of the positioning fixture plates 10 is provided with several positioning pins 11 for inserting into the through holes of the motor end cover. After the motor is initially fixed to the positioning block 8, the two sliding fixture plates 3 are driven close to the motor by the driving component 7. The positioning pins 11 are then inserted into the through holes on the motor end cover, thereby restricting the circumferential rotation of the motor and realizing the circumferential positioning of the motor.

[0031] Reference Figure 3To further improve the accuracy of motor clamping and positioning, a production line stopper 12 and a lifting device 13 are installed below the production line. The production line stopper 12 is a conventional device, located downstream of the production line tooling plate 1 in the direction of movement. It can intercept the production line tooling plate 1 and stop it at a designated position, facilitating further positioning and fixing of the motor. The lifting device 13 can generate a lifting force, which can change the height of the production line tooling plate 1, allowing the motor mounted on the production line tooling plate 1 to move to a suitable height. Thus, the motor no-load test quick clamping device of this embodiment can achieve efficient clamping and fixing of the motor, and can achieve positioning and clamping of the motor in the axial, circumferential, and vertical directions. The lifting device 13 can be a cylinder, hydraulic cylinder, or other type of device that can provide push and pull power. The specific type, specifications, and number can be selected according to actual needs.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
