Description

Technical Field

[0001] The invention relates to the technical field of wear-resistant plate grinding, in particular to a wear-resistant plate grinding processing production line. Background Art

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

[0003] Wear-resistant plate is a plate product specially designed for use in large-area wear conditions. It is a plate product made by surfacing a certain thickness of wear-resistant layer with high hardness and excellent wear resistance on the surface of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity. When surfacing the wear-resistant plate, due to the welding equipment having wire changes, wire breakage, spattering and other problems during the surfacing process, the wear-resistant plate processed at the surfacing station will have some defects that need to be repaired, such as: pit defects, spatter defects, welding wire head defects, etc. In addition, repair welding will be required. For the above defects and repairs, most people currently use manual handheld angle grinders and grinding wheels for grinding to obtain the final product.

[0004] Due to the thickness of the wear-resistant plate, it is impossible for manpower to separate the multiple fallen wear-resistant plates by itself. After grinding one piece, it is necessary to use hoisting and other tools to move the polished wear-resistant plate away and then grind another piece. This method is time-consuming and labor-intensive, and affects the grinding efficiency. It is also impossible for manpower to squat and grind for a long time, and there are no complete protective facilities during grinding, which is easy to cause damage to the workers' bodies. Therefore, we designed a wear-resistant plate grinding production line.

[0005] A polishing platform for aluminum rod production and processing disclosed in the Chinese patent document with publication number CN218427334U includes a main body box, a polishing box and a polishing assembly, wherein the main body box is fixedly arranged on the upper side of the polishing box, and the polishing assembly is arranged in the main body box, and the polishing assembly includes a servo motor, a worm, a worm wheel, a gear, a second rack, a first rack, a sliding plate, a motor mounting box, a polishing motor and a polishing wheel, one end of the worm is rotatably arranged on the inner wall of the main body box, the servo motor is fixedly arranged on the inner wall of the main body box, the output end of the servo motor is fixedly connected to the other end of the worm, the worm wheel is rotatably arranged in the main body box, the worm wheel is meshed with the worm, the gear is rotatably arranged in the main body box, the gear is coaxially fixedly connected to the worm wheel, and the second rack is horizontally slidably arranged on the top inner wall of the main body box. The utility model belongs to the technical field of aluminum rod production and processing, specifically a grinding platform for aluminum rod production and processing, which has good grinding effect and is convenient for collecting waste. However, the grinding platform for aluminum rod production and processing cannot transport wear-resistant plates, and the wear-resistant plates are heavy, making it inconvenient to manually load and unload them.

[0006] A high-precision and high-efficiency polishing production line and method for polishing the resin outside the holes of printed circuit boards are disclosed in the Chinese patent document with the announcement number CN116175330B. The high-precision and high-efficiency polishing production line and method for polishing the resin outside the holes of printed circuit boards include a flat belt conveyor arranged on the pad from left to right, a turnover mechanism for positioning and transporting semi-finished printed circuit boards, and a double-end polishing and protection device for polishing the upper and lower ends of the resin columns in the semi-finished printed circuit boards; the turnover mechanism includes a feed cylinder fixed on the pad, a platform fixed on the active end of the feed cylinder piston rod, a turntable fixed on the output shaft of the stepping motor, and a turntable extending to the right outside the turntable fixed on the top surface of the turntable; the double-end polishing and protection device includes a bracket fixed on the pad, a vertical plate fixed on the left side of the bracket, and a polishing mechanism I and a polishing 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 accuracy, greatly improving the efficiency of resin column grinding, and reducing the workload of workers, but the high-precision and high-efficiency grinding production line and method for grinding the resin outside the printed circuit board holes cannot correct the warped and deformed plates, and the deformed wear-resistant plates cannot fully cooperate with the grinding components, affecting the grinding effect during the grinding process.

[0007] The Chinese patent document with publication number CN213438899U discloses a lifting and grinding platform for an impeller grinder. The lifting and grinding platform includes a workbench, a lifting mechanism, and a servo motor. The workbench is provided with a grinding mechanism, the bottom of the workbench is fixedly connected to the top of the lifting mechanism, and the bottom of the lifting mechanism is connected to the output end of the servo motor. By providing the grinding mechanism, the utility model greatly reduces the workload of workers, reduces labor intensity, enables long-term operation, and improves work efficiency. By providing the workbench, the lifting mechanism, and the servo motor, the servo motor can drive the lifting mechanism and the workbench to move up and down, thereby adjusting the grinding distance between the grinding mechanism and the impeller, and can achieve control of the grinding force, grind the impeller to the appropriate size, and obtain high-quality impeller surface grinding. However, the lifting and grinding platform for the impeller grinder has no transmission function, which is inconvenient for loading and unloading heavy wear-resistant plates.

[0008] In order to solve the above-mentioned deficiencies in the prior art, it is worthwhile to provide a production line for grinding and processing wear-resistant plates. Summary of the Invention

[0010] The purpose of the present invention is achieved through the following technical solutions:

[0012] The grinding platform includes a first support frame, three first conveying chains arranged on both sides and the middle of the first support frame, and a first drive motor driving the three first conveying chains. The first conveying chain driven by the first drive motor is arranged on the first support frame, so that the first conveying chain rotates, driving the wear-resistant plate placed on the grinding platform to move, and the wear-resistant plate is adjusted in position or loaded and unloaded.

[0013] The polishing platform also includes a jacking and fixing platform provided 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 jacking and fixing platform;

[0015] A torsion spring is sleeved on the rotating shaft of the swinging part, and the torsion spring keeps the top of the pad on a horizontal platform;

[0016] The top material of the pad is hard silicone to avoid the situation where the pad is worn and causes unstable support.

[0017] The grinding room is located outside the grinding platform. The main body of the grinding room is made of transparent explosion-proof glass, which is convenient for operators to observe the grinding situation inside through the transparent explosion-proof glass.

[0018] The grinding mechanism includes first slide rails provided on both sides of the top of the grinding mechanism, second slide rails provided between the first slide rails, a movable seat slidably connected to the bottom of the second slide rails, a support arm rotatably connected to the bottom of the movable seat, a connector provided 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;

[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 drive of the two slide rails.

[0021] The transfer platform includes a second support frame, three second conveying chains arranged on both sides and the middle of the second support frame, a second drive motor that drives the three second conveying chains to rotate, a rotating motor arranged at the bottom of the second support frame, a rotating base fixedly connected to the bottom of the rotating motor, and fixed pads fixedly connected to the four corners of the bottom of the rotating base, so as to realize the right-angle transmission and transfer of the wear-resistant plate, put the production line in a state of efficient processing and conveying, and enable the production line to adjust the conveying angle, which is convenient for 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, to avoid interference between the transfer platform and the two and affecting the transfer of the wear-resistant plate.

[0023] The conveying platform includes a third support frame, third conveying chains arranged on both sides and the middle of the conveying platform, a third driving motor for driving the three third conveying chains to rotate, and photoelectric sensors arranged on both ends and 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 transportation 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.

[0028] 3. In this wear-resistant plate grinding processing production line, after the wear-resistant plate is transferred to the transfer platform, the rotating motor drives the entire rotating platform and the wear-resistant plate to rotate until they are docked with the grinding platform, and then the second conveyor chain is started to transfer the wear-resistant plate to the grinding platform, realizing the right-angle transmission and transfer of the wear-resistant plate, making the production line in a state of efficient processing and transportation, and enabling the production line to adjust the transportation angle, which is convenient for the planning and design of the production line.

DETAILED DESCRIPTION

[0048] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0049] Example 1

[0050] like Figures 1 to 18 As shown, the wear-resistant plate grinding processing production line includes a grinding platform 1, a transfer platform 2 arranged on the feed side of the grinding platform 1, a conveying platform 3 arranged on the discharge side of the grinding platform 1 and the side of the transfer platform 2, and a wear-resistant plate 4 for conveying the grinding between the platforms. Protective baffles 5 are provided on both sides of the grinding platform 1, the transfer platform 2 and the conveying platform 3. A grinding room 6 is provided on the outside of the grinding platform 1, a grinding mechanism 7 is provided on the grinding room 6, and a lifting and positioning mechanism 8 is provided on the grinding platform 1.

[0051] like Figures 14 to 18 As shown, the grinding platform 1 includes a first support frame 101, three first conveying chains 102 arranged on both sides and the middle of the first support frame 101, and a first driving motor 103 driving the three first conveying chains 102. The first conveying chain 102 driven by the first driving motor 103 is arranged on the first support frame 101, so that the first conveying chain 102 rotates, driving the wear-resistant plate 4 placed on the grinding platform 1 to move, and the wear-resistant plate 4 is adjusted in position or loaded and unloaded.

[0052] Example 2

[0053] like Figures 16 to 18 As shown, the polishing platform 1 further includes a jacking and fixing platform 104 provided 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 jacking and fixing platform 104;

[0054] The lifting and positioning mechanism 8 includes a plurality of horizontal steel plates 801 fixedly connected between the lifting and fixing platforms 104, a plurality of vertical steel plates 802 fixedly connected to the tops of the horizontal steel plates 801, a plurality of cylinders 803 fixedly connected between the vertical steel plates 802, a swinging portion 804 rotatably connected to the output end of the cylinder 803, and a pad 805 rotatably connected to the output end of the cylinder 803 through the swinging portion 804. By arranging 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 cylinder 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 cooperates with the grinding mechanism to fix the wear-resistant plate, correct and flatten the warped edge of the wear-resistant plate, realize the grinding, straightening and testing procedures, and the whole process can be automatically operated.

[0055] A swinging portion 804 is provided between the cylinder 803 and the backing plate 805, so that the backing plate 805 can be tilted and adjusted within a certain range. When the wear-resistant plate is not flat enough, the backing plate 805 can be tilted to fully fit the bottom surface of the wear-resistant plate, thereby improving the stability of the backing plate 805 supporting the wear-resistant plate 4. The total output load of the cylinder 803 is greater than the sum of the gravity of the wear-resistant plate 4 and the pressure of the grinding mechanism 7.

[0056] Furthermore, a wind suction port is provided at the end of the support arm 704 and is connected to the wind suction device on the grinding room 6 through a hose. When the grinding head 6 is grinding the wear-resistant plate, the wind suction port absorbs the debris and dust generated by the grinding, thereby preventing the dust from flying and affecting the grinding environment. In addition, the airflow generated by the wind suction device can accelerate the heat dissipation efficiency of the wear-resistant plate surface, thereby preventing the grinding head 6 from overheating and affecting its service life.

[0057] A pressure sensor is provided 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 condition of the grinding point is judged according to 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 an emergency stop condition to avoid excessive interaction between the grinding head 706 and the wear-resistant plate and causing wear;

[0058] Furthermore, a lifting slide is provided on the side of the first support frame 101, and the lifting slide is provided on the outside of the protective baffle 5 at the output end of the first support frame 101. A laser flatness measuring instrument is provided on the lifting slide. After the flattening and polishing of the wear-resistant plate are completed, the wear-resistant plate is transported to the conveying platform 3, and the laser flatness measuring instrument is used to detect the flatness of the wear-resistant plate and the polishing condition of the burrs and protrusions on the surface of the wear-resistant plate. When it is detected 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 polishing platform 1 for re-polishing, thereby realizing automatic monitoring of the polishing condition of the assembly line and improving the polishing quality. The laser flatness measuring instrument is set on the lifting slide so that it can be adjusted in height according to the thickness of the wear-resistant plate to be detected, so that the measuring end of the laser flatness measuring instrument remains aligned with the upper surface of the wear-resistant plate to be detected, so that the monitoring structure can adapt to wear-resistant plates of different thicknesses.

[0059] like Figure 18 As shown, a torsion spring is sleeved on the rotating shaft of the swinging portion 804, and the torsion spring keeps the top of the pad 805 on the horizontal platform;

[0060] The top material of the pad 805 is hard silicone. By arranging a torsion spring on the rotating shaft of the swinging part 804, the pad 805 is kept in a horizontal state under normal circumstances, which is convenient for contacting 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 with the bottom of the wear-resistant plate 4. The top material of the pad 805 is set to hard silicone to make it have better corrosion resistance and wear resistance, thereby avoiding the situation where its wear causes unstable support.

[0061] like Figures 14 to 18 As shown, the grinding room 6 is located outside the grinding platform 1. The main material of the grinding room 6 is transparent explosion-proof glass. By setting the material of the grinding room 6 to transparent explosion-proof glass, it can cover and protect the grinding platform 1 to prevent particles flying during the grinding process from causing damage to surrounding equipment and workers. At the same time, it is convenient for the operator to observe the internal grinding situation through the transparent explosion-proof glass.

[0062] Example 3

[0063] like Figures 14 to 18As shown, the grinding mechanism 7 includes first slide rails 701 provided on both sides of the top of the grinding mechanism 7, second slide rails 702 provided between the first slide rails 701, a movable base 703 slidably connected to the bottom of the second slide rails 702, a support arm 704 rotatably connected to the bottom of the movable base 703, a connector 705 provided 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 base 703 and the support arm 704;

[0064] The connecting head 705 is assembled and connected to the support arm 704. A motor is provided at the end of the chain structure 705. The output end of the motor is fixedly connected to the rotating shaft of the grinding head 706.

[0065] The end of the main body of the electric cylinder 707 is rotatably connected to the bottom of the movable base 703, and the output end of the electric cylinder 707 is rotatably connected to the middle of the support arm 704. By arranging a first slide rail 701 and a second slide rail 702 on the grinding chamber 6, the position of the grinding mechanism below is adjusted in the horizontal degree of freedom, and the rotation of the support arm 705 is controlled by the extension and contraction of the electric cylinder 707. When grinding is required, the support arm 705 is rotated downward to make the grinding head 706 contact the wear-resistant plate below, and the motor is started to drive the grinding head 706 to rotate and grind the wear-resistant plate.

[0066] The first slide rail 701 and the second slide rail 702 are both electric slide rails, and the grinding point of the grinding mechanism 7 is automatically adjusted by the drive of the two slide rails.

[0067] Example 4

[0068] like Figures 8 to 13 As shown, the transfer platform 2 includes a second support frame 201, three second conveying chains 202 arranged on both sides and the middle of the second support frame 201, a second drive motor 203 that drives the three second conveying chains 202 to rotate, a rotating motor 204 arranged at the bottom of the second support frame 201, a rotating base 205 fixedly connected to the bottom of the rotating motor 204, and a fixed pad 206 fixedly connected to the four corners of the bottom of the rotating base 205. By arranging a rotating motor 204 at the bottom of the second support frame 201, it can drive the entire transfer platform 2 to rotate. After the wear-resistant plate 4 is transferred to the transfer platform 2, the rotating motor 204 drives the entire rotating platform 2 and the wear-resistant plate 4 to rotate to dock with the grinding platform 1, and then the second conveying chain 202 is started to transfer the wear-resistant plate 4 to the grinding platform 1, realizing the right-angle transmission and transfer of the wear-resistant plate, so that the production line is in a state of efficient processing and transportation, and can enable the production line to adjust the transportation angle, which is convenient for the planning and design of the production line.

[0069] like Figures 8 to 13As shown, the distance between the axis of the rotating base 205 and the grinding platform 1, as well as 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 as well as the conveying platform 3, the transfer platform 2 can remain smooth during the transfer process, avoiding interference between the transfer platform and the two and affecting the transfer of the wear-resistant plate.

[0070] Example 5

[0071] like Figures 6 and 7 As shown, the conveying platform 3 includes a third support frame 301, third conveying chains 302 arranged on both sides and the middle of the conveying platform 3, a third driving motor 303 that drives the three third conveying chains 302 to rotate, and photoelectric sensors 304 arranged on both ends and the middle of the third support frame 301;

[0072] The height of the photoelectric sensor 304 is lower than the top height of the third conveying chain 302. By arranging the photoelectric sensor 304 on the support frame of the conveying platform 3, the number and position of the wear-resistant plates 4 passing through the conveying platform 3 can be monitored, and the rotation and transportation of the transfer platform 2 and the grinding processing of the grinding platform 1 can be coordinated according to the conveying position of the wear-resistant plates, thereby improving the overall coordination of the production line and accelerating the transportation and grinding efficiency of the wear-resistant plates.

[0073] 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 outward.

[0074] The working principle of the present invention is as follows: after the wear-resistant plate is placed on the conveying platform, it is protected and limited by the support plates on both sides so that it can move stably on the conveying platform. After moving into the grinding room, various control devices are coordinated to operate (grinding platform, translation mechanism, lifting and fixing platform and lifting and positioning mechanism). The wear-resistant plate is lifted and fixed by the lifting and positioning mechanism to ensure the basic stability of the grinding working surface. The grinding platform then automatically grinds the entire width of the wear-resistant plate at multiple angles. When grinding, the grinding platform applies downward pressing force to the wear-resistant plate (the pressure range is adjustable), and the warped edges of the wear-resistant plate can be corrected and leveled during grinding. At the same time, the grinding head can be quickly replaced through the connector after working for a long time or when adjusting different grinding discs.

[0075] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
