Description

Technical Field

[0001] This utility model relates to the field of trailer turntable grinding technology, and more specifically, to a trailer turntable grinding device. Background Technology

[0002] The trailer turntable is a key component used to connect the cab and the trailer. It is usually made by stamping. Due to the large load, friction occurs on the surface of the turntable when the cab turns. Therefore, the surface needs to be polished during production to reduce friction. Currently, manual polishing is usually used, which is inefficient. In addition, because the position is not fixed, it needs to be repeatedly adjusted during the polishing process, which affects the polishing quality. Utility Model Content

The grinding disc is located at the other end of the lever, and the connection point between the rotary motor and the lever is located at the center of the lever; the center of the lever and the center of the workpiece are aligned vertically. The grinding area of ​​the grinding disc covers the center of the workpiece. The pressure plate presses down to generate an upward reaction force. Through the action of the lever, the grinding disc also has a downward pressure.

[0005] Furthermore, a hollow tube is installed at one end of the lever, and a sliding shaft is installed inside the hollow tube. A pressure plate is hinged to the lower end of the sliding shaft, and a compression spring is installed between the sliding shaft and the hollow tube. The sliding shaft has a downward tendency to move, and a linear motor is installed on the bracket.

[0007] Furthermore, a high-speed motor is installed at the other end of the lever, and the grinding disc is installed at the rotating end of the high-speed motor. The grinding disc is equipped with a detachable structure, and the grinding disc is connected to the grinding disc through the detachable structure.

[0008] Furthermore, a stabilizing spring is installed between the lever and the rotary motor to keep the lever in a balanced state; the stabilizing spring effectively prevents the lever from swinging erratically.

[0009] Furthermore, a protective cover is installed on the outside of the support, with openings on both sides of the cover, through which the workpiece and the transport system can pass. A negative pressure pipe is installed on the cover, through which external gas can flow to the negative pressure pipe.

[0010] The beneficial effects of this utility model are: through the combined operation of the pressure plate and the grinding disc, the workpiece is fixed while the surface of the workpiece is effectively ground in all directions. The grinding range of the grinding disc covers the center of the workpiece. The pressure plate presses down to generate an upward reaction force. Through the action of the lever, the grinding disc also has a downward pressure. When the grinding disc moves to multiple positions, the surface of the workpiece can be ground.

[0012] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0013] This application provides a trailer turntable grinding device; please refer to [reference needed]. Figures 1-3 It includes workpiece 1, transport system 2, linear motor 3, rotary motor 4, and support 5, and also includes; Lever 6 is hinged to the rotating end of rotary motor 4; The pressure plate 7 is installed at one end of the lever 6 to apply downward pressure to the workpiece 1; The grinding disc 8 is located at the other end of the lever 6, and the connection point between the rotary motor 4 and the lever 6 is located at the center of the lever 6; the center of the lever 6 and the center of the workpiece 1 are aligned vertically. The grinding range of the grinding disc 8 covers the center of the workpiece 1. The pressure plate 7 presses down to generate an upward reaction force. Through the action of the lever 6, the grinding disc 8 also has a downward force.

[0014] In practical applications, the transport system 2 moves the workpiece 1 from left to right, passing through the support 5 in sequence. When the workpiece 1 moves to the center of the support 5 via the infrared sensor, the transport system 2 stops working. Then, the linear motor 3 is extended, which drives the lever 6, the pressure plate 7, and the grinding disc 8 to move downward. The pressure plate 7 presses down to fix the workpiece 1, and the downward pressure of the pressure plate 7 generates an upward reaction force. Through the action of the lever 6, the grinding disc 8 also has downward pressure. Then, the high-speed motor 621 is rotated to perform grinding operations on the corresponding position. The linear motor 3 can be controlled to shorten, and then the rotary motor 4 can be controlled to rotate 90 degrees, so that the grinding disc 8 changes position for grinding. By repeating the above rotation operation, the entire grinding disc 8 can be ground.

[0015] Reference Figure 1 , Figure 2 , Figure 3 A hollow tube 611 is installed at one end of the lever 6, and a sliding shaft 612 is installed inside the hollow tube 611. The pressure plate 7 is hinged to the lower end of the sliding shaft 612. A compression spring 613 is installed between the sliding shaft 612 and the hollow tube 611. The sliding shaft 612 has a downward tendency. The linear motor 3 is installed on the bracket 5.

[0016] In practical applications, the compression spring 613 compresses when the lever 6 moves the pressure plate 7 down to contact the workpiece 1. The spring force of the compression spring 613 applies pressure to the workpiece 1, and the reaction force generated can drive the grinding disc 8 to apply pressure to the workpiece 1.

[0017] Reference Figure 1 , Figure 2 , Figure 3 The lower surface of the pressure plate 7 is provided with anti-slip components 71.

[0018] In practical applications, the anti-slip component 71 can be set as an anti-slip mat, which can enhance the friction between the pressure plate 7 and the workpiece 1.

[0019] Reference Figure 1 , Figure 2 , Figure 3 A high-speed motor 621 is installed at the other end of the lever 6, and a grinding disc 8 is installed at the rotating end of the high-speed motor 621. A detachable structure 622 is provided on the grinding disc 8, and the grinding disc 8 is connected to the grinding disc 8 through the detachable structure 622.

[0020] In practical applications, the high-speed motor 621 can drive the grinding disc 8 to rotate at high speed when it rotates. The detachable structure 622 facilitates the replacement of the grinding disc 8 and controls the weight at both ends of the lever 6 to keep the lever 6 in a balanced state.

[0021] Reference Figure 1 , Figure 2 , Figure 3 A stabilizing spring 41 is installed between lever 6 and rotary motor 4 to keep lever 6 in a balanced state.

[0022] In practical applications, the stabilizing spring 41 effectively prevents the lever 6 from swinging erratically.

[0023] Reference Figure 1 , Figure 2 , Figure 3 A protective cover 51 is installed on the outside of the support 5. The protective cover 51 has openings 52 on both sides, through which the workpiece 1 and the transport system 2 can pass. A negative pressure pipe 53 is installed on the protective cover 51, through which external gas can flow to the negative pressure pipe 53.

[0024] In practical applications, the protective cover 51 can effectively prevent the debris generated during grinding from splashing out, and the gas inside the protective cover 51 can be extracted by external negative pressure equipment, which plays an environmental protection role.
