Description

Technical Field

[0001] This utility model belongs to the field of component testing technology, specifically a thickness testing device for motor components. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by an energized coil (i.e., the stator winding) to act on the rotor, forming a magnetoelectric torque. An electric motor is assembled from several different components, including plate-shaped, block-shaped, rod-shaped, and irregularly shaped components. When measuring the thickness of plate-shaped components, a thickness measuring device is used. However, common thickness measuring devices for components are not convenient for fixing and measuring components of different thicknesses, and their measuring efficiency is low, making it impossible to quickly complete the thickness measurement of components. Therefore, this application proposes a thickness measuring device for electric motor components. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figure 1-5 The present invention includes a base plate 1, with side plates 2 fixedly installed on both sides of the top of the base plate 1. A first slot 3 is formed at the bottom of each side plate 2. A lifting plate 4 is provided above the base plate 1, with both ends of the lifting plate 4 located within the first slots 3 at the bottom of the two side plates 2. A second slot 5 is formed at the upper position of the sides of each side plate 2. A movable moving plate 6 is movably inserted between the two second slots 5. A third slot 8 is formed at the bottom of the moving plate 6, and a moving block 9 is movably installed within the third slot 8. A dial indicator 10 is fixedly installed at the bottom of the moving block 9. The bottom end of the probe of the dial indicator 10 is at the same horizontal plane as the top of the first slot 3. When the lifting plate 4 lifts the component and clamps both ends within the two first slots 3, the probe at the bottom of the dial indicator 10 contacts the top of the plate-shaped component, thus enabling the thickness measurement of the component.

[0020] Meanwhile, a first hydraulic rod 7 is fixedly installed at one end of each of the two side plates 2. The telescopic ends of the two first hydraulic rods 7 extend into the two second slots 5 and are fixedly connected to the two ends of one side of the movable plate 6. By telescopically extending and retracting the two first hydraulic rods 7 at the same time, the two ends of the movable plate 6 can be moved in the corresponding second slots 5 at the same time, which can drive the dial indicator 10 at the bottom of the movable plate 6 to move back and forth.

[0021] In addition, the side of the movable block 9 is provided with a screw hole, and a motor 11 is fixedly installed at one end of the movable plate 6. A screw 12 extending into the third slot 8 is fixedly connected to the output end of the motor 11. The screw 12 is threaded and inserted into the screw hole on the side of the movable block 9. A groove is provided at the end of the third slot 8 away from the motor 11. A bearing 13 is fixedly installed in the groove. The end of the screw 12 that passes through the movable block 9 is fixedly connected to the inner ring wall of the bearing 13. The shape of the movable block 9 is adapted to the third slot 8, so the movable block 9 cannot rotate in the third slot 8. When the motor 11 drives the screw 12 to rotate in the screw hole on the movable block 9, the movable block 9 will move in the third slot 8 along the direction of the screw 12, thereby driving the dial indicator 10 at its bottom to move left and right.

[0022] Furthermore, a second hydraulic rod 16 is fixedly installed at the middle position of the bottom of the base plate 1. The telescopic end of the second hydraulic rod 16 passes through the base plate 1 and is fixedly connected to the middle position of the bottom of the lifting plate 4. By controlling the second hydraulic rod 16, the lifting plate 4 can be pushed to move up and down.

[0023] Furthermore, through holes 17 are provided at the four corners of the top of the base plate 1, and positioning rods 18 are fixedly installed at the four corners of the bottom of the lifting plate 4. The four positioning rods 18 are respectively movably inserted into the four through holes 17 at the top of the base plate 1. The four positioning rods 18 make it easier for the lifting plate 4 to move up and down.

[0024] Furthermore, the top and bottom of the inner walls of the two second slots 5 are provided with sliding grooves 14, and the top and bottom of both ends of the movable plate 6 are provided with two semi-circular grooves. Each semi-circular groove is provided with a rotatable ball 15, and the part of each ball 15 extending out of the semi-circular groove is located in the corresponding sliding groove 14 and can roll inside it. The ball 15 can reduce the contact area between the two ends of the movable plate 6 and the inner wall of the second slot 5, thereby reducing the friction between the two, and making it easier for the two ends of the movable plate 6 to move in the second slot 5.
