Description

Technical Field

[0001] This utility model relates to the field of automotive parts grinding technology, and in particular to a grinding device for automotive parts processing. Background Technology

[0002] During the production and processing of large flat panel components for automobiles, the surface needs to be polished to remove burrs, flash, etc., to ensure the surface accuracy and assembly performance of the components.

[0003] Existing grinding devices for automotive parts processing mostly rely on traditional mechanical clamps for component fixation. These clamps are often rigid structures, making it difficult to perfectly fit the curved or irregular surfaces of automotive parts of different shapes. This can easily cause damage such as indentations and pinch marks on the component surface. Regarding cooling and water resource utilization, the nozzles of the cooling system are usually fixed in position and cannot accurately follow the movement of the grinding area. This results in the cooling water not being applied to the grinding area in a timely and accurate manner, leading to poor cooling performance. This not only makes automotive parts prone to deformation due to high temperatures but also accelerates the wear of grinding tools, shortening their service life. Furthermore, most of the cooling water is used only once and then directly discharged without forming a recycling system, resulting in water waste. Therefore, we propose a grinding device for automotive parts processing. Summary of the Invention

[0004] The purpose of this invention is to provide a grinding device for processing automotive parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for processing automotive parts, comprising a base and a grinding mechanism disposed on the base, wherein a control box for the hydraulically controlled grinding mechanism is fixedly installed at the upper end of the base, and a debris collection mechanism is disposed below the grinding mechanism, the debris collection mechanism comprising a mounting frame and a waste liquid tank, the mounting frame being connected to an electric vacuum suction cup via a debris unloading frame, the waste liquid tank being connected to a water tank via a water pump, and the water tank being connected to a nozzle and a water outlet pipe via a hose.

[0011] The technical effects and advantages of this utility model are as follows: 1. Through the set debris collection mechanism, the electric vacuum suction cup can firmly fix the car parts to be processed in the designated position through negative pressure adsorption. Compared with traditional mechanical clamps, the vacuum adsorption fixing method can adapt to the shape of the car parts and avoid the clamps causing indentations or damage to the surface of the parts. The water in the tank can be delivered to the nozzle through the hose. The nozzle sprays water precisely to the polishing area through the water outlet pipe.

It can not only meet the grinding needs of parts with different thicknesses, but also ensure uniform grinding force through fine adjustment. The cooperation of the first electric slide rod and the first electric slide can realize the sliding of the grinding mechanism in the horizontal X-axis direction, and the cooperation of the second electric slide rod and the second electric slide can realize the sliding in the horizontal Y-axis direction. The combination of the two gives the grinding part the ability to move in all dimensions in the plane, breaking the limitations of the traditional fixed grinding position. It can cover the complex surface and irregular area of ​​automotive parts without frequent adjustment of the fixed position of the parts, greatly improving the adaptability to automotive parts of different shapes and sizes.

The mounting frame 401 is connected to an electric vacuum suction cup 403 through a debris unloading frame 402. The waste liquid tank 404 is connected to a water tank 406 through a water pump 405. The water tank 406 is connected to a nozzle 408 and a water outlet pipe 409 through a hose 407.

[0016] The control box 2 is made of stainless steel with an IP54 protection rating, preventing the intrusion of grinding debris. It is fixed to the upper part of the base 1 with bolts. The internal components include a hydraulic control valve group, a PLC controller, and operation buttons. It can receive manual commands and output pressure oil to the grinding mechanism 3 through the hydraulic oil circuit to realize the lifting, lowering, grinding intensity adjustment and other action control of the grinding mechanism 3, solving the problem of low precision of traditional manual adjustment.

[0017] Mounting bracket 401 is fixedly installed at the center of the surface of base 1. A chip feeder 402 is fixedly installed at the center of mounting bracket 401. An electric vacuum suction cup 403 is fixedly installed at the center of the inside of chip feeder 402.

[0018] The waste feeding rack 402 has a funnel-shaped structure with a filter screen inside. It is fixed to the center of the mounting frame 401 by welding or bolts. The electric vacuum suction cup 403 is fixed to the center of the waste feeding rack 402 by a flange. The suction surface of the electric vacuum suction cup 403 is in contact with the contact surface of the automotive parts to fix the parts.

[0019] Waste liquid tank 404 is fixedly installed at the bottom of mounting bracket 401, water pump 405 is fixedly installed on the surface of base 1, the input end of water pump 405 is fixedly installed at the outlet of waste liquid tank 404, and the output end of water pump 405 extends into the interior of water tank 406.

[0020] Waste liquid tank 404 is bolted to the bottom of mounting bracket 401, with the tank opening directly aligned with the lower diameter of debris discharge rack 402, ensuring that all falling debris and cooling water can fall into waste liquid tank 404 without any leakage. The input end of water pump 405 is inserted into the outlet of waste liquid tank 404, and the output end of water pump 405 extends into water tank 406 through a rigid pipe. The end of the rigid pipe is three to five centimeters away from the bottom of water tank 406 to prevent the sediment at the bottom of water tank 406 from being drawn back.

[0021] The bottom of the water tank 406 is fixedly installed on the surface of the base 1. One end of the hose 407 is fixedly installed on the water outlet end of the water tank 406. One end of the nozzle 408 is fixedly connected to the other end of the hose 407. The water outlet pipe 409 is fixedly installed on the other end of the nozzle 408.

[0022] One end of the hose 407 is fixed to the water outlet of the water tank 406 by a clamp, and the other end is connected to one end of the nozzle 408 by a threaded connector. The connector is equipped with a sealing ring made of silicone to prevent water leakage. The nozzle 408 can rotate around the connector to facilitate adjustment of the spray direction.

[0023] Specifically, the electric vacuum suction cup 403 can firmly fix the automotive parts to be processed in a designated position through negative pressure adsorption. Compared with traditional mechanical clamps, the vacuum adsorption fixing method can adapt to the shape of the automotive parts and avoid the clamps causing indentations or damage to the surface of the parts. The water in the water tank 406 can be delivered to the nozzle 408 through the hose 407. The nozzle 408 sprays water precisely onto the polishing area through the water outlet pipe 409, which can cool the polishing area in real time and prevent the automotive parts from deforming due to excessive temperature caused by friction heat during polishing. At the same time, it can also reduce the temperature of the polishing tools and extend the service life of the polishing tools. The water pump 405 connected to the bottom of the waste liquid tank 404 can draw waste liquid into the water tank 406 for recycling, reducing the waste of water resources.

[0024] Please see the appendix Figure 1 - Appendix Figure 4 The grinding mechanism 3 includes a hydraulic telescopic rod 301, a bearing plate 302 is fixedly installed on the upper end of the hydraulic telescopic rod 301, a first electric slide rod 303 is fixedly installed on the upper end of the bearing plate 302, a first electric slide 304 is slidably connected inside the first electric slide rod 303, a second electric slide rod 305 is fixedly installed on the upper end of the first electric slide 304, and a second electric slide 306 is slidably connected inside the second electric slide rod 305.

[0025] The hydraulic telescopic rod 301, controlled by the hydraulic system within the control box 2, can drive the grinding mechanism 3 to rise and fall vertically, meeting the grinding distance requirements of automotive parts of varying thicknesses. The first electric slide rod 303 uses a ball screw slide table, horizontally fixed to the upper end of the support plate 302 by bolts. The axis of the first electric slide rod 303 is parallel to the long side of the support plate 302, and it has a built-in servo motor. The first electric slide 304 is the matching slider for the first electric slide rod 303, sliding through internal nut engagement with the screw. The second electric slide rod 305 has the same specifications as the first electric slide rod 303, and is orthogonally distributed at a 90-degree angle to it, forming an XY two-dimensional motion system. This allows adjustment of the grinding unit 309 to any position on the horizontal plane, enabling grinding of different areas of the automotive parts. The second electric slide 306 is the matching slider for the second electric slide rod 305, with the same sliding parameters as the first electric slide 304.

[0026] The second electric slide 306 has a mounting plate 307 fixedly installed on its side. The upper and lower ends of the mounting plate 307 are fixedly installed with grinding parts 309. The upper and lower ends of one side of the mounting plate 307 have mounting holes 308 through it. The water outlet pipe 409 is fixedly installed inside the mounting hole 308.

[0027] The grinding section 309 includes a silicon carbide grinding wheel and an asynchronous motor. The motor is fixed to the upper and lower ends of the mounting plate 307 via flanges. The motor output shaft is connected to the grinding wheel via a key, and the speed is adjustable, allowing for grinding operations on automotive parts. The water outlet pipe 409 is fixedly installed in the mounting hole 308 to ensure that the water flow follows the grinding action.

[0028] Specifically, the hydraulic telescopic rod 301 enables the grinding mechanism 3 to be precisely raised and lowered in the vertical direction, flexibly adjusting the distance between the grinding part 309 and the automotive parts. This not only meets the grinding needs of parts with different thicknesses but also ensures uniform grinding force through fine adjustments. The cooperation between the first electric slide rod 303 and the first electric slide 304 enables the grinding mechanism 3 to slide in the horizontal X-axis direction, while the cooperation between the second electric slide rod 305 and the second electric slide 306 enables sliding in the horizontal Y-axis direction. The combination of the two enables the grinding part 309 to have full-dimensional movement capability in the plane, breaking the limitations of the traditional fixed grinding position. It can cover the complex surfaces and irregular areas of automotive parts without frequent adjustments to the fixed position of the parts, greatly improving the adaptability to automotive parts of different shapes and sizes.

[0029] The working principle of this utility model is as follows: This utility model is a grinding device for processing automotive parts. First, the automotive parts to be ground are placed on the electric vacuum suction cup 403. The electric vacuum suction cup 403 is started through the control box 2, and the parts are fixed by negative pressure adsorption. The water level in the water tank 406 is checked to ensure that the cooling system can operate normally.

[0030] By operating the hydraulic telescopic rod 301 to extend and retract through the control box 2, the bearing plate 302 and the upper components are raised and lowered, and the grinding part 309 is adjusted to a suitable initial height; the first electric slide rod 303 is controlled to drive the first electric slide 304 to slide along the X-axis, and the second electric slide rod 305 drives the second electric slide 306 to slide along the Y-axis, so that the grinding part 309 on the mounting plate 307 is aligned with the position to be ground.

[0031] The grinding unit 309 is started by the control box 2, and the grinding wheel rotates; at the same time, the nozzle 408 is turned on, and the cooling water in the water tank 406 is sprayed out from the water outlet pipe 409 through the hose 407 and the nozzle 408 to cool the grinding contact area.

[0032] According to the preset program or manual operation, the first electric slide 304 and the second electric slide 306 are controlled to slide, which drives the grinding part 309 to move along the required path on the surface of the component to complete all-round grinding; the grinding debris is intercepted in the debris feeder 402, and the wastewater falls into the waste liquid tank 404.

[0033] Start the water pump 405 to pump the waste liquid in the waste liquid tank 404 to the water tank 406 for recycling. After completion, turn off the grinding section 309, the nozzle 408, and the water pump 405 in sequence; control the hydraulic telescopic rod 301 to raise the grinding mechanism 3 through the control box 2, turn off the electric vacuum suction cup 403, remove the parts and clean the residual debris from the device.
