Abstract
Description
Technical Field
[0001] This utility model relates to a quick changeover test structure for servo motor stators. Background Technology
[0002] Currently, one of our company's servo motor products requires soldering the PCB board to the stator. To promptly detect defects such as cold solder joints and missing solder joints, comprehensive performance testing is necessary. Different types of motors have different UVW contact positions on their PCB boards, thus requiring specialized testing fixtures. When producing multiple models simultaneously, the number of specialized fixtures required is also large, necessitating frequent fixture changes, which is time-consuming and impacts production efficiency, increasing costs. To address these issues, the following utility model patent was designed and manufactured. Utility Model Content
[0003] To address the aforementioned problems, the purpose of this utility model is to provide a servo motor stator quick changeover test structure that improves production efficiency and reduces input costs.
[0004] The technical solution for realizing this utility model is as follows:
[0005] A servo motor stator quick changeover test structure includes a base plate, two clamping assemblies, two guide assemblies, a guide plate, and probe assemblies. The two guide assemblies are disposed opposite each other on the base plate and connected by the guide plate. Two clamping assemblies are disposed opposite each other on the guide plate. A motor is disposed on the base plate between the two guide assemblies, and a through hole is provided in the center of the guide plate at a position corresponding to the motor. The guide plate outside the through hole forms a support ring, and a plurality of probe assemblies are disposed on the support ring.
[0006] The clamping assembly includes two fixed seats, a limiting block, a handle, and a drive rod; the two fixed seats are arranged opposite each other outside the limiting block, and the drive rod is placed on the limiting block between the two fixed seats; the handle is placed above the two fixed seats, one side of the handle is hinged to the corresponding fixed seat through a first connecting rod, and the other side of the handle is hinged to the corresponding fixed seat through a second connecting rod; the bottom surface of the end of the handle near the fixed seat is connected to the drive rod.
[0007] The guide assembly includes a guide seat and a guide shaft inserted into the guide seat; the exposed end of the guide shaft passes through the upper guide plate and is installed inside the limiting block; guide sleeves are fitted on the guide shafts below the guide plate.
[0008] The probe assembly includes a probe fixing block mounted on a support ring by a wing bolt, and a probe is provided at one end of the probe fixing block that extends into the through hole of the guide plate.
[0009] A fixture for placing a motor is installed on the base plate between the two guide components, and a metal grounding ring is fitted on the top surface of the fixture.
[0010] By adopting the above technical solution, the guide plate can stably reciprocate up and down through the cooperation of the guide components and the drive of the clamping components. Since the probe components are located on the guide plate, the movement of the guide plate will also drive the up and down movement of the probe components, thereby completing the height adjustment of the probe components. Then, the probe components test the motor. The whole testing process is convenient and fast, and the switching is stable. It can meet the requirements for testing any stator with a PCB board, thus improving production efficiency. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0019] A servo motor stator quick-change test structure includes a base plate 1, two clamping assemblies 2, two guide assemblies 3, a guide plate 4, and a probe assembly 5. The two guide assemblies are disposed opposite each other on the base plate and connected by the guide plate. Two clamping assemblies are disposed opposite each other on the guide plate. A motor 7 is disposed on the base plate between the two guide assemblies, and a through hole 8 is provided in the center of the guide plate corresponding to the position of the motor. The guide plate outside the through hole forms a support ring, and several probe assemblies are disposed on the support ring. The guide plate, through the cooperation of the guide assemblies and driven by the clamping assemblies, can stably perform up-and-down reciprocating motion. Since the probe assemblies are located on the guide plate, the movement of the guide plate will also drive the up-and-down movement of the probe assemblies, thereby completing the height adjustment of the probe assemblies. The probe assemblies then test the motor.
[0020] The clamping assembly includes two fixed seats 2.1, a limiting block 2.2, a handle 2.3, and a drive rod 2.4. The two fixed seats are arranged opposite each other outside the limiting block, and the drive rod is placed on the limiting block between the two fixed seats. The handle is placed above the two fixed seats, with one side of the handle hinged to the corresponding fixed seat via a first connecting rod 2.5, and the other side of the handle hinged to the corresponding fixed seat via a second connecting rod. The bottom surface of the handle near the fixed seat is connected to the drive rod. The rotation point of the handle is located on the fixed seat. As the handle rotates around the fixed seat, the drive rod is connected to the guide plate below, and the rotation of the handle drives the guide plate to reciprocate up and down through the drive rod.
[0021] The guiding assembly includes a guide seat 3.1 and a guide shaft 3.2 inserted into the guide seat. The exposed end of the guide shaft passes through the upper guide plate and is installed inside the limiting block. Guide sleeves 3.3 are fitted onto the guide shafts below the guide plate. The guide plate moves up and down via the guide sleeves. Because the guide seat and guide shaft are fixed, the position of the guide plate remains unchanged during its up and down movement.
[0022] The probe assembly includes a probe fixing block 5.2 mounted on the support ring by a wing bolt 5.1, and a probe 5.3 is provided at one end of the probe fixing block that extends into the through hole of the guide plate. Depending on the PBC board, the position of the probe can be changed by adjusting the probe fixing block; depending on the length of the iron core, the contact position of the probe can be controlled by adjusting the limiting block; the three probes correspond to the UVW phase sequence of the motor.
[0023] A fixture for placing the motor is installed on the base plate between the two guide components, and a metal grounding ring 9 is fitted on the top surface of the fixture. An insulating base is fixed to the base plate; the metal grounding ring is placed on the insulating base, and the equipment test ground wire is connected through the metal grounding ring. To facilitate testing of stator cores with different outer diameters, a metal ring of a corresponding size is fitted onto the existing metal grounding ring, allowing for quick switching.
[0024] The working principle of this utility model will be explained below:
[0025] Place the stator with the PCB board inside the metal grounding ring of the fixture, ensuring complete contact between the bottom of the iron core and the metal ring. Then, loosen the wing screws on the limit block, allowing the quick-clamping device to engage as shown in the diagram (in the clamping state), so that the probe head on the guide plate contacts the PCB board and is in the clamping state. Tighten the wing screws to complete the height position adjustment. Next, release the quick-clamping device, loosen the wing screws on the probe fixing block, and adjust the probe to the UVW contact of the PCB. Tighten the wing screws to complete the contact position adjustment. After completing the above steps, the product can be tested.
[0026] After the test is completed, the stator can be easily removed by simply releasing the quick clamping device. The whole process is simple to operate and the switching is stable. It can meet the requirements for testing any stator with a PCB board, thus improving production efficiency.
