Description

Technical Field

[0001] This utility model relates to the field of wear-resistant plate grinding technology, and in particular to a wear-resistant plate grinding production line. Background Technology

[0002] Wear-resistant steel plates are used in plate-shaped components in industries such as power, machinery, building materials, metallurgy, cement, coal, and chemicals.

[0003] Wear-resistant steel plates are sheet metal products specifically designed for use in environments with large-area wear. They are made by bonding a certain thickness of wear-resistant layer with high hardness and excellent wear resistance to the surface of ordinary low-carbon steel or low-alloy steel with a welding method, which has good toughness and ductility. During the welding process of wear-resistant steel plates, due to issues such as wire replacement, wire breakage, and spatter, some defects may occur in the wear-resistant steel plates processed at the welding station, which need to be repaired. These defects include pit defects, spatter defects, and wire end defects. In addition, re-welding may be required. Currently, most of the above defects and repairs are done manually using a handheld angle grinder with a grinding wheel to grind the surface and obtain the final product.

[0004] Because wear-resistant plates are thick and heavy, it is impossible for a person to separate multiple pieces of wear-resistant plates by themselves. It is necessary to grind one piece and then use hoisting tools to move the ground wear-resistant plate away before grinding another piece. This method is time-consuming and labor-intensive and affects grinding efficiency. It is also impossible for people to squat and lie down for a long time to grind, and there are no complete protective facilities during grinding, which can easily cause injury to the workers. Therefore, we designed a wear-resistant plate grinding production line.

[0005] A grinding platform for aluminum rod production and processing is disclosed in Chinese patent document CN218427334U. This grinding platform includes a main body box, a grinding box, and a grinding assembly. The main body box is fixedly mounted on the upper side of the grinding box. The grinding assembly is located inside the main body box and includes a servo motor, a worm gear, a worm wheel, a gear, a second rack, a first rack, a sliding plate, a motor mounting box, a grinding motor, and a grinding wheel. One end of the worm gear is rotatably mounted on the inner wall of the main body box. The servo motor is fixedly mounted on the inner wall of the main body box, and its output end is fixedly connected to the other end of the worm gear. The worm wheel is rotatably mounted inside the main body box and meshes with the worm gear. The gear is rotatably mounted inside the main body box and is coaxially fixedly connected to the worm wheel. The second rack is horizontally slidably mounted on the inner wall of the top of the main body box. This utility model belongs to the field of aluminum rod production and processing technology. Specifically, it is a grinding platform for aluminum rod production and processing that has a good grinding effect and is easy to collect waste materials. However, this grinding platform for aluminum rod production and processing cannot convey wear-resistant plates. The wear-resistant plates are heavy and inconvenient for manual loading and unloading.

[0006] A high-precision and high-efficiency grinding production line and method for grinding resin outside holes of printed circuit boards is disclosed in Chinese patent document CN116175330B. The high-precision and high-efficiency grinding production line and method for grinding resin outside holes of printed circuit boards includes a flat belt conveyor arranged sequentially from left to right on a pad, a turnover mechanism for positioning and transferring semi-finished printed circuit boards, and a double-end grinding and protection device for grinding the upper and lower ends of resin pillars inside the semi-finished printed circuit boards. The turnover mechanism includes a feed cylinder fixed on the pad, a platform fixed on the working end of the piston rod of the feed cylinder, a turntable fixed on the output shaft of a stepper motor, and a turnover table extending to the right outside the turntable fixed on the top surface of the turntable. The double-end grinding and protection device includes a bracket fixed on the pad, a vertical plate fixed on the left side of the bracket, and grinding mechanism I and grinding mechanism II respectively arranged on the upper and lower ends of the vertical plate. The beneficial effects of the above invention are: greatly improving the grinding precision, greatly improving the grinding efficiency of resin columns, and reducing the workload of workers. However, the high-precision and high-efficiency grinding production line and method for grinding the resin outside the holes of printed circuit boards cannot correct the warped and deformed boards. The deformed wear-resistant boards cannot fully cooperate with the grinding components, which affects the grinding effect during the grinding process.

[0007] A lifting and grinding platform for an impeller grinder is disclosed in Chinese patent document CN213438899U. This platform includes a worktable, a lifting mechanism, and a servo motor. The worktable houses the grinding mechanism, and its bottom is fixedly connected to the top of the lifting mechanism. The bottom of the lifting mechanism is connected to the output end of the servo motor. This invention significantly reduces the workload and labor intensity of workers by incorporating the grinding mechanism, enabling long-term operation and improving work efficiency. The worktable, lifting mechanism, and servo motor allow the servo motor to drive the lifting mechanism and worktable up and down, thereby adjusting the grinding distance between the grinding mechanism and the impeller. This allows for control of the grinding force, ensuring the impeller is ground to the appropriate size and resulting in high-quality impeller surface grinding. However, this lifting and grinding platform lacks a conveying function, making it inconvenient for loading and unloading heavy wear-resistant plates.

[0008] To address the shortcomings of the existing technology, providing a production line for grinding wear-resistant plates is a problem worthy of research. Summary of the Invention

[0009] The purpose of this invention is to overcome the inconvenience of manually adjusting the position of heavy stacked wear-resistant plates, and to provide a wear-resistant plate grinding production line that achieves the technical effect of automatic transmission and grinding of wear-resistant plates.

[0010] The objective of this utility model is achieved through the following technical solution:

[0011] A wear-resistant plate grinding production line includes a grinding platform, a transfer platform located on one side of the grinding platform's inlet, a conveying platform located on both the grinding platform's outlet side and the transfer platform's side, and wear-resistant plates being conveyed between the platforms. Protective baffles are provided on both sides of the grinding platform, transfer platform, and conveying platform. A grinding chamber is provided outside the grinding platform, a grinding mechanism is provided on the grinding chamber, and a lifting and positioning mechanism is provided on the grinding platform.

[0012] The grinding platform includes a first support frame, three first conveyor chains disposed on both sides and in the middle of the first support frame, and a first drive motor for driving the three first conveyor chains. By setting the first conveyor chains driven by the first drive motor on the first support frame, the first conveyor chains are rotated, which drives the wear-resistant plates placed on the grinding platform to move, thereby adjusting the position of the wear-resistant plates or loading and unloading them.

[0013] The grinding platform also includes a lifting and fixing platform disposed at the bottom of the front and rear ends of the first support frame, and the lifting and positioning mechanism is fixedly connected to the lifting and fixing platform.

[0014] The lifting and positioning mechanism includes several horizontal steel plates fixedly connected between the lifting fixed platform, several vertical steel plates fixedly connected to the top of the horizontal steel plates, several cylinders fixedly connected between the vertical steel plates, a swing part rotatably connected to the output end of the cylinders, and a pad plate rotatably connected to the output end of the cylinders through the swing part, so as to realize the grinding, straightening and inspection process, which can be automatically operated throughout the process.

[0015] A torsion spring is sleeved on the pivot of the swinging part, and the torsion spring keeps the top of the pad on the horizontal platform.

[0016] The top of the pad is made of hard silicone to prevent wear and tear from causing unstable support.

[0017] The grinding chamber is located outside the grinding platform. The main body of the grinding chamber is made of transparent explosion-proof glass, which allows the operator to easily observe the grinding process inside through the transparent explosion-proof glass.

[0018] The grinding mechanism includes a first slide rail on both sides of the top of the grinding mechanism, a second slide rail between the first slide rails, a movable seat slidably connected to the bottom of the second slide rail, a support arm rotatably connected to the bottom of the movable seat, a connector at the end of the support arm, a grinding head rotatably connected to the end of the connector, and an electric cylinder rotatably connected between the movable seat and the support arm.

[0019] The connector is assembled and connected to the support arm, and a motor is provided at the end of the connector. The output end of the motor is fixedly connected to the rotating shaft of the grinding head.

[0020] The end of the main body of the electric cylinder is rotatably connected to the bottom of the movable seat, and the output end of the electric cylinder is rotatably connected to the middle of the support arm. The first slide rail and the second slide rail are both electric slide rails, and the grinding point of the grinding mechanism is automatically adjusted by the driving of the two slide rails.

[0021] The transfer platform includes a second support frame, three second conveyor chains located on both sides and in the middle of the second support frame, a second drive motor that drives the three second conveyor chains to rotate, a rotary motor located at the bottom of the second support frame, a rotary base fixedly connected to the bottom of the rotary motor, and fixed pads fixedly connected to the four corners of the bottom of the rotary base. This enables the right-angle transfer of wear-resistant plates, allowing the production line to operate in a state of efficient processing and conveying. It also allows the production line to adjust the conveying angle, facilitating the planning and design of the production line.

[0022] The distance between the axis of the rotating base and the grinding platform, as well as the distance between the axis of the rotating base and the conveying platform, are both greater than the rotation radius of the transfer platform, so as to avoid interference between the transfer platform and the two platforms, which would affect the transfer of the wear-resistant plate.

[0023] The conveying platform includes a third support frame, third conveying chains located on both sides and in the middle of the conveying platform, a third drive motor that drives the three third conveying chains to rotate, and photoelectric sensors located at both ends and in the middle of the third support frame.

[0024] The height of the photoelectric sensor is lower than the top height of the third conveyor chain, which improves the overall coordination of the production line and speeds up the conveying and grinding efficiency of the wear-resistant plates.

[0025] The inner side of the protective baffle is coated with a wear-resistant coating, and both ends of the protective baffle are bent outwards.

[0026] Positive and beneficial effects: 1. This wear-resistant plate grinding production line, through the conveyor platform, lifting and fixing platform, grinding platform, transfer platform, and conveying platform, enables the processing and grinding of wear-resistant plates in a highly efficient processing and conveying state. During processing, the wear-resistant plates can be fixed, and the warped edges of the wear-resistant plates can be corrected and flattened. The grinding, straightening, and inspection process can be completed automatically. In addition, the grinding room is equipped with corresponding protective facilities to clean the surface of the wear-resistant plates.

[0027] 2. The wear-resistant plate grinding production line has a lifting and fixing platform set on the first support frame to improve the overall stability of the grinding platform. When the wear-resistant plate is transferred to the grinding platform, the output end of the cylinder is extended to lift the pad and the wear-resistant plate above to a certain height, so that the grinding mechanism can grind the surface of the wear-resistant plate.

[0028] 3. In this wear-resistant plate grinding production line, after the wear-resistant plate is transferred to the transfer platform, the rotary motor drives the entire rotating platform and the wear-resistant plate to rotate until they are connected with the grinding platform. Then, the second conveyor chain is started to transfer the wear-resistant plate to the grinding platform, realizing the right-angle transfer of the wear-resistant plate. This allows the production line to be in a state of efficient processing and conveying, and also allows the production line to adjust the conveying angle, which is convenient for the planning and design of the production line.

Detailed Implementation

[0048] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0049] like Figures 1 to 18As shown, the wear-resistant plate grinding production line includes a grinding platform 1, a transfer platform 2 located on one side of the feed inlet of the grinding platform 1, a conveying platform 3 located on the discharge side of the grinding platform 1 and one side of the transfer platform 2, and wear-resistant plates 4 conveyed between the platforms for grinding. Protective baffles 5 are provided on both sides of the grinding platform 1, the transfer platform 2 and the conveying platform 3. A grinding chamber 6 is provided outside the grinding platform 1. A grinding mechanism 7 is provided on the grinding chamber 6. A lifting and positioning mechanism 8 is provided on the grinding platform 1.

[0050] like Figures 14 to 18 As shown, the grinding platform 1 includes a first support frame 101, three first conveyor chains 102 disposed on both sides and in the middle of the first support frame 101, and a first drive motor 103 for driving the three first conveyor chains 102. By setting the first conveyor chains 102 driven by the first drive motor 103 on the first support frame 101, the first conveyor chains 102 are rotated, which drives the wear-resistant plate 4 placed on the grinding platform 1 to move, thereby adjusting the position of the wear-resistant plate 4 or loading and unloading it. Example 2

[0051] like Figures 16 to 18 As shown, the grinding platform 1 also includes a lifting and fixing platform 104 disposed at the bottom of the front and rear ends of the first support frame 101, and the lifting and positioning mechanism 8 is fixedly connected to the lifting and fixing platform 104.

[0052] The lifting and positioning mechanism 8 includes several horizontal steel plates 801 fixedly connected between the lifting and fixing platforms 104, several vertical steel plates 802 fixedly connected to the top of the horizontal steel plates 801, several cylinders 803 fixedly connected between the vertical steel plates 802, a swing part 804 rotatably connected to the output end of the cylinders 803, and a pad 805 rotatably connected to the output end of the cylinders 803 through the swing part 804. By setting the lifting and fixing platform 104 on the first support frame 101 as a support, the overall stability of the grinding platform 1 is improved. When the wear-resistant plate is transferred to the grinding platform 1, the output end of the cylinders 803 is extended to lift the pad 805 and the upper wear-resistant plate 4 to a certain height, so that the grinding mechanism 7 can grind the surface of the wear-resistant plate. During processing, the lifting and positioning mechanism and the grinding mechanism can fix the wear-resistant plate and correct and flatten the warped edges of the wear-resistant plate, realizing the grinding, straightening and inspection process, which can be run automatically throughout the process.

[0053] A swing part 804 is provided between the cylinder 803 and the pad 805, so that the pad 805 can tilt and adjust the angle within a certain range. When the wear-resistant plate is not flat enough, the pad 805 can tilt and fully fit the bottom surface of the wear-resistant plate, thereby improving the stability of the pad 805 in supporting the wear-resistant plate 4. The total output load of the cylinder 803 is greater than the sum of the weight of the wear-resistant plate 4 and the pressure of the grinding mechanism 7.

[0054] Furthermore, a wind-powered dust suction port is provided at the end of the support arm 704 and is connected to the wind-powered dust suction device on the grinding chamber 6 through a hose. During the grinding process of the grinding head 6 grinding the wear-resistant plate, the wind-powered dust suction port absorbs the debris and dust generated during grinding, preventing dust from flying and affecting the grinding environment. In addition, the airflow generated by the wind-powered dust suction device can accelerate the heat dissipation efficiency of the wear-resistant plate surface, preventing the grinding head 6 from overheating and affecting its service life.

[0055] A pressure sensor is installed between the support arm 704 and the grinding head 706 to monitor the pressure applied to the wear-resistant plate in real time and transmit the output pressure to the control terminal of the grinding device. The grinding status of the grinding point is judged based on the pressure feedback from the pressure sensor. When the grinding head 706 collides with the wear-resistant plate, the pressure sensor can detect the pressure surge in time, thereby triggering the emergency stop condition to avoid excessive interaction between the grinding head 706 and the wear-resistant plate, which may cause wear.

[0056] Furthermore, a lifting slide rail is provided on the side of the first support frame 101. The lifting slide rail is located outside the protective baffle 5 at the output end of the first support frame 101. A laser flatness measuring instrument is installed on the lifting slide rail. After the flattening and grinding of the wear-resistant plate is completed, when the wear-resistant plate is conveyed into the conveying platform 3, the laser flatness measuring instrument detects the flatness of the wear-resistant plate and the grinding condition of the burrs and protrusions on the surface of the wear-resistant plate. When it detects that there are protrusions on the surface of the wear-resistant plate that have not been thoroughly cleaned, the wear-resistant plate is returned to the grinding platform 1 for re-grinding. This realizes automatic monitoring of the grinding condition of the production line, improves the grinding quality, and the laser flatness measuring instrument is set on the lifting slide rail so that its height can be adjusted according to the thickness of the wear-resistant plate being tested. This keeps the measuring end of the laser flatness measuring instrument aligned with the upper surface of the wear-resistant plate being tested, so that the monitoring structure can be adapted to wear-resistant plates of different thicknesses.

[0057] like Figure 18 As shown, a torsion spring is sleeved on the pivot of the swing part 804, and the torsion spring keeps the top of the pad 805 on the horizontal platform.

[0058] The top of the pad 805 is made of hard silicone. By setting a torsion spring on the pivot of the swing part 804, the pad 805 is kept in a horizontal state under normal circumstances, which facilitates contact with the wear-resistant plate 4 above for support. At the same time, when the wear-resistant plate 4 is uneven, the pad 805 can overcome the torsion of the torsion spring and tilt to a certain extent to fit against the bottom of the wear-resistant plate 4. Setting the top of the pad 805 to be made of hard silicone gives it good corrosion resistance and wear resistance, avoiding the situation where the support is unstable due to wear.

[0059] like Figures 14 to 18As shown, the grinding chamber 6 is located outside the grinding platform 1. The main material of the grinding chamber 6 is transparent explosion-proof glass. By setting the material of the grinding chamber 6 to transparent explosion-proof glass, it can cover and protect the grinding platform 1, preventing the particles flying during the grinding process from causing damage to the surrounding equipment and workers. At the same time, it is convenient for the operator to observe the grinding situation inside through the transparent explosion-proof glass. Example 3

[0060] like Figures 14 to 18 As shown, the grinding mechanism 7 includes a first slide rail 701 disposed on both sides of the top of the grinding mechanism 7, a second slide rail 702 disposed between the first slide rails 701, a movable seat 703 slidably connected to the bottom of the second slide rail 702, a support arm 704 rotatably connected to the bottom of the movable seat 703, a connector 705 disposed at the end of the support arm 704, a grinding head 706 rotatably connected to the end of the connector 705, and an electric cylinder 707 rotatably connected between the movable seat 703 and the support arm 704.

[0061] The connector 705 is assembled and connected to the support arm 704. A motor is provided at the end of the connector 705, and the output end of the motor is fixedly connected to the rotating shaft of the grinding head 706.

[0062] The end of the main body of the electric cylinder 707 is rotatably connected to the bottom of the movable seat 703, and the output end of the electric cylinder 707 is rotatably connected to the middle of the support arm 704. By setting the first slide rail 701 and the second slide rail 702 on the grinding chamber 6, the position of the grinding mechanism below is adjusted in the horizontal degree of freedom. The extension and retraction of the electric cylinder 707 controls the rotation of the support arm 705. When grinding is required, the support arm 705 is rotated downward so that the grinding head 706 contacts the wear-resistant plate below, and the motor is started to drive the grinding head 706 to rotate to grind the wear-resistant plate.

[0063] Both the first slide rail 701 and the second slide rail 702 are electric slide rails, and the grinding point of the grinding mechanism 7 is automatically adjusted by the driving of the two slide rails. Example 4

[0064] like Figures 8 to 13As shown, the transfer platform 2 includes a second support frame 201, three second conveyor chains 202 located on both sides and in the middle of the second support frame 201, a second drive motor 203 that drives the three second conveyor chains 202 to rotate, a rotary motor 204 located at the bottom of the second support frame 201, a rotary base 205 fixedly connected to the bottom of the rotary motor 204, and fixing pads 206 fixedly connected to the four corners of the bottom of the rotary base 205. By setting the rotary motor 204 at the bottom of the second support frame 201, it can drive the entire transfer platform 2 to rotate. When the wear-resistant plate 4 is transferred to the transfer platform 2, the rotary motor 204 drives the entire rotary platform 2 and the wear-resistant plate 4 to rotate until they are connected to the grinding platform 1. Then, the second conveyor chains 202 are started to transfer the wear-resistant plate 4 to the grinding platform 1, realizing the right-angle transfer of the wear-resistant plate. This allows the production line to be in a state of efficient processing and conveying, and also allows the production line to adjust the conveying angle, which is convenient for the planning and design of the production line.

[0065] like Figures 8 to 13 As shown, the distance between the axis of the rotating base 205 and the grinding platform 1, and the distance between the axis of the rotating base 205 and the conveying platform 3 are both greater than the rotation radius of the transfer platform 2. By limiting the distance between the transfer platform 2 and the grinding platform 1 and the conveying platform 3, the transfer platform 2 can maintain smooth operation during the transfer process, avoiding interference between the transfer platform and the two platforms that would affect the transfer of the wear-resistant plate. Example 5

[0066] like Figures 6 to 7 As shown, the conveying platform 3 includes a third support frame 301, third conveying chains 302 disposed on both sides and in the middle of the conveying platform 3, a third drive motor 303 that drives the three third conveying chains 302 to rotate, and photoelectric sensors 304 disposed on both ends and in the middle of the third support frame 301.

[0067] The height of the photoelectric sensor 304 is lower than the top height of the third conveyor chain 302. By setting the photoelectric sensor 304 on the support frame of the conveyor platform 3, it can monitor the quantity and position of the wear-resistant plates 4 passing through the conveyor platform 3, and coordinate the rotation and transfer of the transfer platform 2 and the grinding processing of the grinding platform 1 according to the conveying position of the wear-resistant plates, thereby improving the overall coordination of the production line and accelerating the conveying and grinding efficiency of the wear-resistant plates.

[0068] like Figures 2 to 18 As shown, the inner side of the protective baffle 5 is coated with a wear-resistant coating, and both ends of the protective baffle 5 are bent outwards.

[0069] The working principle of this utility model is as follows: After the wear-resistant plate is placed on the conveying platform, it moves stably on the conveying platform through the protection and limiting of the support plates on both sides. After moving into the grinding chamber, various control devices (grinding platform, translation mechanism, lifting and fixing platform and lifting and positioning mechanism) work in coordination. The lifting and positioning mechanism lifts and fixes the wear-resistant plate to ensure the basic stability of the grinding surface. Then, the grinding platform automatically grinds the entire surface of the wear-resistant plate from multiple angles. During grinding, the grinding platform applies downward pressure to the wear-resistant plate (the pressure range is adjustable). During grinding, the warped edges of the wear-resistant plate can be corrected and leveled. At the same time, after long-term work or when adjusting different grinding discs, the grinding head can be quickly replaced through the connector.

[0070] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
