Description

Technical Field

[0001] This utility model relates to the field of new energy motor assembly technology, specifically a press-fitting machine for assembling new energy motors. Background Technology

[0002] The assembly of new energy motors includes several steps such as component preparation and cleaning, stator assembly, rotor assembly, bearing assembly, and overall motor assembly and debugging. First, component preparation and cleaning involves inspecting each component to check for damage or deformation of the iron core and the insulation performance of the windings. The insulation resistance is tested using an insulation resistance tester, and the required insulation resistance value is generally several hundred megohms or higher. Then, the stator, rotor, shaft, and bearings are cleaned with a cleaning solvent. Next, the stator iron core, stator windings, rotor iron core, and rotor windings are installed and connected. After the stator and rotor of the motor are assembled, the bearings are installed. Finally, the end covers and outer casing are installed before motor debugging can begin.

[0003] In the current technology, the bearing installation process in the assembly of new energy motors uses a press machine to install the bearings onto the output shaft of the motor. However, due to the different models and sizes of new energy motors, different diameter clamps need to be changed each time a bearing of a different size is installed in order to clamp the bearings of different sizes, which increases the workload of the workers. Therefore, a press machine for assembling new energy motors is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a press-fitting machine for assembling new energy motors. It has the advantage of easily clamping bearings of different sizes, solving the problem of bearing installation in the assembly of new energy motors. The press-fitting machine is used to install bearings onto the output shaft of the motor. However, due to the different models and sizes of new energy motors, different diameter clamps need to be changed each time different sizes of bearings are installed, which increases the workload of workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a press-fitting machine for assembling new energy motors, comprising a press-fitting machine, an assembly frame provided on the press-fitting machine, a shaft clamp provided on the assembly frame, and a press-fitting structure and an adjustment structure provided on the assembly frame;

[0006] The press-fit structure includes a support frame that is slidably mounted on an assembly frame. Inside the support frame, two connecting blocks with one end extending through and to the outside are slidably mounted. Abutment plates are fixedly mounted on the front of each of the two connecting blocks. Fixing clamps for holding bearings are mounted on the bottom of the two abutment plates. A pressing component for controlling the simultaneous lifting and lowering of the two abutment plates is slidably mounted on the assembly frame. A sliding component for supporting the sliding of the pressing component and the support frame is provided on the assembly frame.

[0007] Furthermore, the adjustment structure includes a threaded rod rotatably mounted inside the support frame and extending through both ends to the outside of it. Two connecting blocks are respectively threaded onto the outer surface of the threaded rod.

[0008] Furthermore, the assembly frame is fixedly installed on the press machine, the press machine is fixedly installed with a control unit, and the assembly frame is provided with a placement slot for placing the output shaft of the new energy motor.

[0009] Furthermore, a limiting strip is fixedly installed on the rear side wall of the inner cavity of the support frame, and limiting grooves are opened on the back of both connecting blocks. The outer surface of the limiting strip is slidably connected to the inner wall of the two limiting grooves respectively.

[0010] Furthermore, the fixing fixture includes two V-groove blocks and a rubber pad, the rubber pad being fixedly installed in the groove of the V-groove block, and the V-groove block being fixedly installed at the bottom of the abutment plate.

[0011] Furthermore, the pressing component includes two electric push rods and two mounting platforms. The electric push rods are fixedly mounted on the mounting platforms, and the telescopic ends of the electric push rods are fixedly connected to the top of the abutment plate.

[0012] Furthermore, the sliding component includes a horizontal slide rail and two vertical slide rails. Both mounting platforms are mounted on the horizontal slide rails, and the support frame is mounted on the two vertical slide rails. The horizontal slide rails and the two vertical slide rails are all fixedly mounted on the assembly frame.

[0013] Furthermore, the transmission component includes a belt and two pulleys, with the two pulleys respectively fixedly mounted on the outer surfaces of the asynchronous motor output shaft and the threaded rod, and the belt drive is mounted on the two pulleys.

[0014] Furthermore, a hydraulic cylinder is fixedly installed on the assembly frame, and the shaft clamp is fixedly connected to the telescopic end of the hydraulic cylinder. There are two hydraulic cylinders and two shaft clamps.

[0015] Furthermore, V-shaped grooves are provided on the opposite sides of both abutment plates, and a clamp for fixing the asynchronous motor is fixedly installed on the top of the support frame.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] This press-fitting machine for assembling new energy motors, equipped with a press-fitting structure and an adjustment structure, utilizes an asynchronous motor as a drive source and mechanically controls two connecting blocks to move in opposite directions. The moving connecting blocks then drive a contact plate and control the two V-groove blocks in the fixed fixture to move in opposite directions, facilitating the placement of bearings of different sizes into the fixed fixture. The asynchronous motor then drives the output shaft to rotate in reverse, controlling the two V-groove blocks to clamp the bearings. A pressing component controls the downward movement of the fixed fixture, pressing the bearings onto the motor output shaft held by the shaft clamp. This eliminates the need to change fixtures when installing bearings of different sizes, thus avoiding increased labor intensity for workers and enhancing the practicality of the press-fitting machine for assembling new energy motors.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3This embodiment of a press-fitting machine for assembling a new energy motor includes a press-fitting machine 1, an assembly frame 2 on the press-fitting machine 1, a shaft clamp 3 on the assembly frame 2, a press-fitting structure and an adjustment structure on the assembly frame 2, the assembly frame 2 being fixedly mounted on the press-fitting machine 1, a control platform being fixedly mounted on the press-fitting machine 1, a placement slot for placing the output shaft of the new energy motor being provided on the assembly frame 2, a hydraulic cylinder being fixedly mounted on the assembly frame 2, and the shaft clamp 3 being fixedly connected to the telescopic end of the hydraulic cylinder, with two hydraulic cylinders and two shaft clamps 3.

[0024] In this embodiment, the press-fit structure includes a support frame 41 slidably mounted on the assembly frame 2. Two connecting blocks 42 with one end extending through and to the outside are slidably mounted inside the support frame 41. A limit strip is fixedly mounted on the rear side wall of the inner cavity of the support frame 41. Limit grooves are opened on the back of the two connecting blocks 42. The outer surface of the limit strip is slidably connected to the inner wall of the two limit grooves, which facilitates limiting the left and right movement trajectory of the connecting blocks 42. Abutment plates 43 are fixedly mounted on the front of the two connecting blocks 42. A fixing clamp 44 for clamping bearings is installed at the bottom of the two abutment plates 43. The fixing clamp 44 includes two V-groove blocks and a rubber pad. The rubber pad is fixedly mounted in the groove of the V-groove block. The V-groove block is fixedly mounted at the bottom of the abutment plate 43, which facilitates the clamping of bearings of different sizes using the two V-groove blocks. A pressing component 45 for controlling the simultaneous lifting and lowering of the two abutment plates 43 is slidably mounted on the assembly frame 2. A sliding component 46 for supporting the sliding of the pressing component 45 and the support frame 41 is provided on the assembly frame 2.

[0025] The pressing component 45 includes two electric push rods and two mounting platforms. The electric push rods are fixedly mounted on the mounting platforms, and the telescopic ends of the electric push rods are fixedly connected to the top of the abutment plate 43, so that the abutment plate 43 can be moved up and down by the telescopic movement of the electric push rods, thereby realizing the bearing pressing action.

[0026] It should be noted that the sliding component 46 includes a horizontal slide rail and two vertical slide rails. Both mounting platforms are mounted on the horizontal slide rails, and the support frame 41 is mounted on the two vertical slide rails. The horizontal slide rails and the two vertical slide rails are fixedly mounted on the assembly frame 2, which facilitates the left and right sliding of the two electric push rods with the abutment plate 43, and facilitates the up and down sliding of the support frame 41.

[0027] By adopting the above technical solution, the two connecting blocks 42 are controlled to move to the opposite side by adjusting the structure, so that the moving connecting blocks 42 drive the V-groove blocks in the fixing clamp 44 to move synchronously through the abutment plate 43, thereby using the two V-groove blocks to fix and clamp the bearing. Then, the two electric push rods in the pressing component 45 simultaneously control the two abutment plates 43 to move downward, thereby using the abutment plates 43 to press the bearing onto the output shaft of the new energy motor.

[0028] In this embodiment, the adjustment structure includes a threaded rod 47 rotatably mounted inside the support frame 41, with both ends passing through and extending to the outside. Two connecting blocks 42 are threadedly mounted on the outer surface of the threaded rod 47, so that rotating the threaded rod 47 can control the two connecting blocks 42 to move to the opposite side or the opposite side. An asynchronous motor 48 is fixedly mounted on the top of the support frame 41. A transmission component 49 for driving the threaded rod 47 to rotate is provided on one side of the asynchronous motor 48. The transmission component 49 includes a belt and two pulleys. The two pulleys are fixedly mounted on the output shaft of the asynchronous motor 48 and the outer surface of the threaded rod 47, respectively. The belt drive is mounted on the two pulleys, so that the rotating output shaft drives the threaded rod 47 to rotate through the belt.

[0029] V-shaped grooves are provided on the opposite sides of the two abutment plates 43, and a clamp for fixing the asynchronous motor 48 is fixedly installed on the top of the support frame 41, so that the output shaft of the new energy motor can pass through the two abutment plates 43.

[0030] Using the above technical solution, the output shaft of the new energy motor is clamped and fixed on the assembly frame 2 using the shaft clamp 3. Then, the bearing to be installed is placed in the fixing clamp 44, the asynchronous motor 48 is started and the output shaft is driven to rotate. The rotating output shaft drives the threaded rod 47 to rotate through the belt in the transmission component 49, so that the rotating threaded rod 47 controls the two connecting blocks 42 to move to the opposite side.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, the press-fitting machine for assembling new energy motors uses shaft clamps 3 to clamp and fix the output shaft of the new energy motor onto the assembly frame 2. Then, the bearing to be installed is placed in the fixing clamp 44. The asynchronous motor 48 is started and drives the output shaft to rotate. The rotating output shaft drives the threaded rod 47 to rotate via the belt in the transmission component 49. The rotating threaded rod 47 controls the two connecting blocks 42 to move to opposite sides. The moving connecting blocks 42 drive the V-groove blocks in the fixing clamp 44 to move synchronously via the abutment plate 43. The bearing is fixedly clamped by the two V-groove blocks. Then, the two electric push rods in the pressing component 45 simultaneously control the two abutment plates 43 to move downward, thereby pressing the bearing onto the output shaft of the new energy motor using the abutment plates 43.
