Description

Technical Field

[0001] This utility model relates to the field of grinding table technology, and more specifically, to a lifting structure for a grinding table. Background Technology

[0002] Grinding platforms ensure high precision and surface finish on workpieces. They are characterized by uniform structure, compact composition, and absence of casting defects such as sand holes, porosity, and shrinkage cavities. They also offer excellent wear resistance and high precision. Grinding of flat surfaces is typically performed after fine grinding. When manually grinding flat surfaces, abrasive is applied to the grinding plate (grinding tool), and the workpiece is held and moved in a linear reciprocating motion or a figure-eight motion. After grinding for a certain period, the workpiece is rotated 90°–180° to prevent tilting. Small flat surfaces, square holes, and narrow slits on the workpiece can also be ground by hand using the grinding tool. Flat surfaces on simple parts produced in large batches can also be ground on a surface grinding machine.

[0003] Most grinding tables are currently placed on the ground and their height cannot be adjusted, making them unsuitable for workers of different heights to grind workpieces. Moreover, during the grinding process, two workers usually stand on either side of the grinding table and push the workpiece back and forth on the table to achieve the grinding work. However, there are no protective measures on the edges of the grinding table, so the pushed workpiece is easy to slip off the grinding table and break. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing grinding tables are not only inconvenient to adjust in height, but also prone to causing workpieces to detach and break during the grinding process.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A lifting structure for a grinding table includes a base, a lifting mechanism disposed on top of the base, a support platform disposed on top of the lifting mechanism, and a grinding table disposed on top of the support platform, and further includes:

[0007] The protective mechanism includes two baffles symmetrically slidably mounted on the top sides of the support platform along its length, a roller rotatably mounted on the side walls at both ends of the base, a protrusion mounted on the bottom of the baffle, a suspension rope mounted between the protrusion and the roller, an elastic reset member mounted between the bottom of the baffle and the bottom of the support platform, and a transmission component mounted on the base that can drive the roller to rotate when the support platform moves vertically.

[0008] A collection component, which is disposed on the side wall of the support platform, is used to collect the debris generated during workpiece grinding.

[0009] As a preferred technical solution of this application, the elastic reset member includes a fixed cylinder with a bottom support platform, a sliding column slidably disposed inside the fixed cylinder, a spring disposed between the top of the sliding column and the inner top wall of the fixed cylinder, and a connecting plate disposed between the bottom of the baffle and the bottom of the sliding column.

[0010] As a preferred technical solution of this application, the transmission assembly includes toothed plates slidably disposed on both sides of the top of the base, push-pull columns movably disposed between the top of the toothed plates and the bottom of the support platform, rotating rods rotatably disposed inside the base, and gears disposed on the rod wall and meshing with the toothed plates. The end of the rotating rod away from the base is connected to the end face of the scroll.

[0011] As a preferred technical solution of this application, the lifting mechanism includes a cylinder disposed on the top of the base and a piston rod disposed at the output end of the cylinder, the top of the piston rod being connected to the bottom of the support platform.

[0012] As a preferred technical solution of this application, the collecting component includes collecting frames disposed on both sides of the top of the support table along the width direction, and the end face of the grinding table along the width direction is provided with a sliding surface that gradually slopes toward the collecting frames.

[0013] As a preferred technical solution of this application, the base is further provided with protective boxes on both side walls, the scroll is located inside the protective boxes, and the top of the protective boxes is provided with slots for the suspension rope to pass through.

[0014] As a preferred technical solution of this application, the top of the base has two symmetrically arranged sliding grooves, the inside of the base has an installation groove that communicates with the sliding grooves, the toothed plate is slidably disposed inside the sliding grooves, and the rotating rod is rotatably disposed on the inner wall of the installation groove and extends to the outside of the base.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By using the lifting mechanism, when a worker needs to use the grinding table to grind the workpiece, the cylinder can be activated. The piston rod drives the grinding table, which is set on the top of the support platform, to move up and down, thereby adjusting the height of the grinding table. This makes it easier for workers of different heights to grind the workpiece, thus improving the adaptability of the device and solving the problem that the height of the grinding table in the prior art cannot be adjusted, making it inconvenient for workers of different heights to perform grinding operations.

[0017] 2. With the protective mechanism in place, when the grinding table is raised, the support platform will drive the roller to rotate through the transmission component and release the hoisting rope. At this time, the elastic reset component will cause the baffles on both sides of the support platform to spring up, blocking and protecting the sides of the grinding table. This can prevent the workpiece from being pushed and sliding on the grinding table and falling off, causing damage to the workpiece. When the device is not in use, the lifting mechanism will drive the grinding table to move down and reset. At this time, the transmission component will drive the roller to reverse, thereby winding up the hoisting rope and pulling the baffles down to store it. This solves the problem in the prior art where the lack of protective measures on both sides of the grinding table makes it easy for the workpiece to slide off the grinding table.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] like Figures 1 to 5As shown, this embodiment proposes a lifting structure for a grinding table, including a base 1, a lifting mechanism disposed on the top of the base 1, a support platform 2 disposed on the top of the lifting mechanism, and a grinding table 3 disposed on the top of the support platform 2. It also includes a protective mechanism and a collection component. The protective mechanism is disposed on both sides of the support platform 2. When the lifting mechanism moves the support platform 2 upward, the protective mechanism will block and protect both sides of the grinding table 3. The collection component is disposed on the side wall of the support platform 2 and is used to collect the debris generated by the grinding of the workpiece.

[0027] When a worker needs to use the grinding table 3 to grind a workpiece, the lifting mechanism can move the grinding table 3 up and down to adjust its height, making it easier for workers of different heights to operate. As the lifting mechanism raises the grinding table 3, a protective mechanism extends from both sides of the support platform 2 to block and protect the sides of the grinding table 3, preventing the workpiece from sliding off the grinding table 3 and breaking during grinding. Furthermore, grinding generates a significant amount of debris, which slides to the edge of the grinding table 3 as the workpiece moves back and forth. The collection component collects and processes this debris, improving the cleanliness of the grinding table 3 surface. This not only enhances the adaptability of the grinding device but also improves the grinding quality of the workpiece.

[0028] The lifting mechanism includes a cylinder 5 located on the top of the base 1 and a piston rod 501 located at the output end of the cylinder 5. The top of the piston rod 501 is connected to the bottom of the support platform 2. When the cylinder 5 is started, the piston rod 501 can drive the support platform 2 to move vertically up and down, thereby facilitating the adjustment of the height of the grinding table 3 and making it convenient for different workers to use.

[0029] like Figures 1 to 5 As shown, in a preferred embodiment, based on the above method, the protective mechanism further includes two baffles 4 symmetrically slidably mounted on the top two sides of the support platform 2 along the length direction, a roller 6 rotatably mounted on the side walls at both ends of the base 1, a protrusion 401 mounted on the bottom of the baffles 4, a suspension rope 601 mounted between the protrusion 401 and the roller 6, an elastic reset member mounted between the bottom of the baffles 4 and the bottom of the support platform 2, and a transmission assembly mounted on the base 1 that can drive the roller 6 to rotate when the support platform 2 moves vertically.

[0030] The elastic reset component includes a fixed cylinder 7 set at the bottom of the support platform 2, a sliding column 8 slidably set inside the fixed cylinder 7, a spring 701 set between the top of the sliding column 8 and the inner top wall of the fixed cylinder 7, and a connecting plate 9 set between the bottom of the baffle 4 and the bottom of the sliding column 8.

[0031] The transmission assembly includes toothed plates 10 slidably disposed on both sides of the top of the base 1, push-pull columns 11 movably disposed between the top of the toothed plates 10 and the bottom of the support platform 2, rotating rod 12 rotatably disposed inside the base 1, and gear 1201 disposed on the rod wall of the rotating rod 12 and meshing with the toothed plates 10. The end of the rotating rod 12 away from the base 1 is connected to the end face of the scroll 6.

[0032] When the cylinder 5 and piston 501 drive the support platform 2 to move upward, the push-pull column 11 at the bottom of the support platform 2 will drive the toothed plate 10 to move towards both sides of the base 1, which will then drive the rotating rod 12 equipped with gear 1201 to rotate. The rotating rod 12 will drive the reel 6 to rotate and release the hoisting rope 601. At this time, the spring 701 will be released from its force, causing the sliding column 8 to slide upward. Then, through the connecting plate 9, the baffle 4 will slide upward and extend from both sides of the top of the support platform 2, thus blocking both sides of the grinding table 3. When two workers stand on both sides of the grinding table 3 and push the workpiece against each other, the baffle 4 can prevent the workpiece from sliding to the edge of the grinding table 3 and falling and getting damaged. After the workpiece is ground, the cylinder 5 drives the grinding table 3 and the support platform 2 to move downward and reset. At this time, the push-pull column 11 will drive the toothed plate 10 to move towards the middle of the base 1, which will then drive the rotating rod 12 and the reel 6 to reverse and reset. The reel 6 will wind up the hoisting rope 601, thereby pulling the baffle 4 downward and causing the baffle 4 to slide downward and be stored.

[0033] In addition, the collection component includes collection frames 13 set on both sides of the top of the support table 2 along the width direction, and the end face of the grinding table 3 along the width direction is provided with a sliding surface 301 that gradually slopes toward the collection frame 13. When the workpiece slides back and forth on the top of the grinding table 3 for grinding, a lot of debris will be generated. The workpiece sliding back and forth will push the debris to the two sides of the grinding table 3. At this time, the debris will slide into the collection frame 13 through the inclined sliding surface 301, which makes it easy to collect and process the debris, keep the surface of the grinding table 3 clean, and make it easier for the workpiece to be ground.

[0034] The base 1 is also provided with protective boxes 14 on both sides. The scroll 6 is located inside the protective box 14. The top of the protective box 14 is provided with a slot for the hanging rope 601 to pass through. The protective box 14 can protect the scroll 6 and prevent foreign objects from touching the scroll 6 and affecting the normal operation of the protective mechanism.

[0035] The base 1 has two symmetrically arranged sliding grooves on its top. The base 1 has an installation groove inside that communicates with the sliding grooves. The toothed plate 10 is slidably arranged inside the sliding grooves, and the rotating rod 12 is rotatably arranged on the inner wall of the installation groove and extends to the outside of the base 1. The sliding grooves allow the toothed plate 10 to move more stably, while the installation grooves facilitate the installation of the rotating rod 12 and the gear 1201.

[0036] The working principle of this utility model is as follows: When a worker needs to use the grinding table 3 to grind the workpiece, the cylinder 5 is started. The piston column 501 can drive the support table 2 to move vertically up and down, so as to facilitate the adjustment of the height of the grinding table 3 and make it convenient for different workers to use. Furthermore, when the cylinder 5 drives the support platform 2 to move upward, the push-pull column 11 at the bottom of the support platform 2 will drive the toothed plate 10 to move towards both sides of the base 1, which will then drive the rotating rod 12 equipped with gear 1201 to rotate. The rotating rod 12 will drive the reel 6 to rotate and release the hoisting rope 601. At this time, the spring 701 will be released from its force, causing the sliding column 8 to slide upward. Then, through the connecting plate 9, the baffle 4 will slide upward and extend from both sides of the top of the support platform 2, thus blocking both sides of the grinding table 3. When two workers stand on both sides of the grinding table 3 and push the workpiece against each other, the baffle 4 can prevent the workpiece from sliding to the edge of the grinding table 3 and falling and getting damaged. After the workpiece is ground, the cylinder 5 drives the grinding table 3 and the support platform 2 to move downward and reset. At this time, the push-pull column 11 will drive the toothed plate 10 to move towards the middle of the base 1, which will then drive the rotating rod 12 and the reel 6 to reverse and reset. The reel 6 will wind up the hoisting rope 601, thereby pulling the baffle 4 downward and causing the baffle 4 to slide downward and be stored.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
