Description

Technical Field

[0001] The utility model relates to the technical field of marble production, in particular to a positioning table for polishing artificial marble. Background Art

[0002] Artificial marble is made by using crushed stones of natural marble or granite as filling materials, and cement, gypsum and unsaturated polyester resin as adhesives, and is formed by stirring, grinding and polishing. Therefore, artificial marble has many characteristics of natural marble. With the development of modern construction, artificial marble is an ideal decorative material for modern architecture.

[0003] Currently, existing devices, such as patent number: CN217801032U, disclose a positioning table for polishing artificial marble, including a support table body. A guide frame is fixedly connected to the bottom end of the support table body, and a fixed rotating shaft is installed inside the guide frame through a bearing. A connecting rod is inserted into the guide frame, and a moving frame is fixedly connected to the end of the connecting rod away from the guide frame. By rotating the fixed rotating shaft, the utility model can make two driving blocks move relative to each other on its surface, so that the connecting rod can drive the two moving frames to approach each other. At this time, through the movement of the moving frame, the fixed clamping plate can clamp and limit the artificial marble on the surface of the support table body, which is convenient for polishing the surface of the artificial marble, avoiding the need to place the artificial marble on the ground for long-term bending polishing. When the limit pin abuts against the surface of the fixed rotating shaft, the fixed rotating shaft can be limited when it does not rotate.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems:

[0005] 1. The existing device directly places the marble on the surface of the support table body. When the staff polishes the marble, they need to walk around the corners of the marble manually for polishing, and the marble cannot be rotated. The polishing personnel need to walk around the marble by themselves for polishing, which is time-consuming, laborious and affects the polishing efficiency.

[0006] 2. The support table body of the existing device is not provided with a lifting mechanism. The height and polishing habits of each staff member are different, and the fixed support table body cannot be adjusted according to the usage habits of different staff members, so that the staff is not easy to reach the most comfortable working state. Content of the Utility Model

[0007] (1) Technical Problems to be Solved

[0008] Aiming at the deficiencies of the prior art, the utility model provides a positioning table for polishing artificial marble, which solves the technical problems that the existing devices affect the polishing efficiency and cannot adjust the height during use.

[0009] (II) Technical solutions

[0010] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0011] A positioning table for polishing artificial marble, including a bottom plate. At the center of the top surface of the bottom plate, a cylinder is fixedly installed. The output end of the cylinder is fixedly connected with an operation plate. Both ends of the operation plate are fixedly connected with connecting blocks. Both ends of the bottom plate are fixedly connected with limiting rods. The two limiting rods are respectively slidably connected with the two connecting blocks. Four springs are arranged between the bottom plate and the operation plate. The top surface of the operation plate is fixedly connected with a clamping mechanism and an operation table. A driving mechanism is fixedly arranged on the side wall of the operation plate. The driving mechanism is connected with the operation table. The driving mechanism includes a fixing plate. The clamping mechanism includes a connecting frame and a threaded sleeve. The operation table includes a damping turntable.

[0012] Preferably: The fixing plate is fixedly connected to the side wall of the operation plate. The fixing plate is rotatably connected with a rotating shaft. One end of the rotating shaft is fixedly connected with a crank. The other end of the rotating shaft is fixedly connected with a driving bevel gear. The driving bevel gear is meshed and clamped with a driven bevel gear. The driven bevel gear is fixedly connected with a rotating shaft. The rotating shaft is also fixedly installed with a first gear.

[0013] Preferably: The outer wall of the upper half of the damping turntable is fixedly connected with a toothed ring. The toothed ring is meshed and clamped with the first gear. The rotating shaft is rotatably connected to the top surface of the operation plate.

[0014] Preferably: The connecting frame is L-shaped. The connecting frame is fixedly installed on the top surface of the operation plate. The threaded sleeve is fixedly connected to the end of the connecting frame away from the operation plate. The threaded sleeve is threadedly connected with a lead screw. One end of the lead screw is fixedly connected with a hand wheel, and the other end is fixedly connected with a first turntable. The end of the first turntable away from the lead screw is fixedly connected with a pressing plate. The end of the pressing plate away from the first turntable is fixedly connected with a contact plate.

[0015] Preferably: The material of the contact plate is rubber. A plurality of grooves are opened on the surface of the contact plate away from the pressing plate. The axes of the lead screw, the hand wheel, the first turntable, the pressing plate, the contact plate and the damping turntable are all located on the same vertical line.

[0016] (III) Beneficial effects

[0017] 1. Since the damping turntable has damping, when polishing marble, a part of the force transmitted by the polishing machine will not drive the damping turntable to rotate. After one side of the marble is polished, the operating table is driven to rotate by the driving mechanism. Because the first gear and the toothed ring are a small gear driving a large gear, a greater torque can be provided, enabling the operator to overcome the damping inherent in the damping turntable to rotate. The damping turntable drives the marble to rotate. Due to the setting of the first turntable, the pressing plate and the contact plate can rotate with the marble, so the rotation of the marble can be achieved. After the operator polishes one side, there is no need to walk to the unpolished side of the marble by himself, saving time and effort, and solving the problem that the existing device cannot rotate the marble during use, and the operator needs to walk to the unpolished position by himself, thus affecting the polishing efficiency.

[0018] 2. After clamping the marble, start the air cylinder to push the operating plate to rise. The spring provides elastic force to reduce the burden of the air cylinder. The spring cooperates with the connecting block to make the operating plate rise smoothly, enabling the operating plate to drive the entire operating table to lift and lower for height adjustment, solving the problem that the existing device cannot adjust the height, and facilitating the operator to adjust the marble to the most comfortable position for polishing.

DETAILED DESCRIPTION OF THE INVENTION

[0025] By providing a positioning tabletop for artificial marble polishing in the embodiments of the present application, the problems that the existing devices affect the polishing efficiency and cannot adjust the height during use are effectively solved.

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the technical solutions in the embodiments of the present application effectively solve the technical problems that the existing devices affect the polishing efficiency and cannot adjust the height during use. The general idea is as follows:

[0027] In view of the problems existing in the prior art, the present utility model provides a positioning tabletop for artificial marble polishing, including a bottom plate 1. A cylinder 2 is fixedly installed at the center of the top surface of the bottom plate 1. The output end of the cylinder 2 is fixedly connected with an operation plate 3. Connecting blocks 301 are fixedly connected to both ends of the operation plate 3. Limiting rods 102 are fixedly connected to both ends of the bottom plate 1. The two limiting rods 102 are respectively slidably connected with the two connecting blocks 301. Four springs 101 are arranged between the bottom plate 1 and the operation plate 3. A clamping mechanism 5 and an operation table 6 are fixedly connected to the top surface of the operation plate 3. A driving mechanism 4 is fixedly arranged on the side wall of the operation plate 3. The driving mechanism 4 is connected with the operation table 6. The driving mechanism 4 includes a fixing plate 401. The clamping mechanism 5 includes a connecting frame 501 and a threaded sleeve 502. The operation table 6 includes a damping turntable 601.

[0028] The fixing plate 401 is fixedly connected to the side wall of the operation plate 3. A rotating shaft 402 is rotatably connected to the fixing plate 401. One end of the rotating shaft 402 is fixedly connected with a crank 403. The other end of the rotating shaft 402 is fixedly connected with a driving bevel gear 404. The driving bevel gear 404 is meshed and clamped with a driven bevel gear 405. The driven bevel gear 405 is fixedly connected with a rotating shaft 406. A first gear 407 is also fixedly installed on the rotating shaft 406.

[0029] A tooth ring 602 is fixedly connected to the outer wall of the upper half of the damping turntable 601.

[0030] The tooth ring 602 is meshed and clamped with the first gear 407. The rotating shaft 406 is rotatably connected to the top surface of the operation plate 3. The connecting frame 501 is L-shaped. The connecting frame 501 is fixedly installed on the top surface of the operation plate 3. The threaded sleeve 502 is fixedly connected to the end of the connecting frame 501 away from the operation plate 3. A lead screw 503 is threadedly connected to the threaded sleeve 502.

[0031] One end of the lead screw 503 is fixedly connected to a handwheel 504, and the other end is fixedly connected to a first turntable 505. One end of the first turntable 505 away from the lead screw 503 is fixedly connected to a pressing plate 506. One end of the pressing plate 506 away from the first turntable 505 is fixedly connected to a contact plate 507. The material of the contact plate 507 is rubber, and a plurality of grooves are formed on one side of the contact plate 507 away from the pressing plate 506.

[0032] The axes of the lead screw 503, the handwheel 504, the first turntable 505, the pressing plate 506, the contact plate 507 and the damping turntable 601 are all located on the same vertical line. Since the damping turntable 601 has damping, when polishing marble, a part of the force transmitted by the polishing machine will not drive the damping turntable 601 to rotate. When one side of the marble is polished, the driving mechanism 4 drives the operating table 6 to rotate. Because the first gear 407 and the toothed ring 602 are a small gear driving a large gear, a greater torque can be provided, enabling the staff to overcome the damping inherent in the damping turntable 601 to rotate. The damping turntable 601 drives the marble to rotate. Due to the setting of the first turntable 505, the pressing plate 506 and the contact plate 507 can rotate with the marble, so the rotation of the marble can be realized. After the staff polishes one side, they don't need to walk to the unpolished side of the marble by themselves, which saves time and effort and solves the problem that the existing device cannot rotate the marble during use and the staff needs to walk to the unpolished position by themselves, thus affecting the polishing efficiency.

[0033] Working principle:

[0034] First step, place the marble on the top surface of the damping turntable 601, and use the handwheel 504 to drive the lead screw 503 to rotate. The lead screw 503 rotates in the internal thread of the threaded sleeve 502, so that the lead screw 503 drives the first turntable 505, the pressing plate 506 and the contact plate 507 to move downward. Finally, the surface of the contact plate 507 with grooves also contacts the marble. Since the contact plate 507 is made of rubber and is provided with grooves, the contact plate 507 can be pressed against the uneven surface of the marble under the push of the lead screw 503, realizing the clamping of the marble.

[0035] Second step, after clamping the marble, start the cylinder 2 to push the operating plate 3 to rise. The spring 101 provides elastic force to reduce the burden of the cylinder 2. The spring 101 cooperates with the connecting block 301 to make the operating plate 3 rise smoothly, realizing that the operating plate 3 can drive the entire operating table 6 to lift and lower, for adjusting the height and facilitating the use of the staff.

[0036] Step 3: Since the damping turntable 601 has damping, when polishing marble, a part of the force transmitted by the polishing machine will not drive the damping turntable 601 to rotate. After one side of the marble is polished, turn the crank 403 to drive the rotating shaft 402 to rotate. The rotating shaft 402 drives the driving bevel gear 404 to rotate. The driving bevel gear 404 drives the engaged driven bevel gear 405 to rotate. The driven bevel gear 405 drives the rotating shaft 406 to rotate. The rotating shaft 406 drives the first gear 407 to rotate. The first gear 407 drives the toothed ring 602, thereby driving the damping turntable 601 to rotate. Since the first gear 407 and the toothed ring 602 are a small gear driving a large gear, a greater torque can be provided, enabling the operator to overcome the damping inherent in the damping turntable 601 and rotate it. The damping turntable 601 drives the marble to rotate. Due to the setting of the first turntable 505, the pressing plate 506 and the contact plate 507 can rotate with the marble, so the rotation of the marble can be achieved. After the operator polishes one side, there is no need to walk to the unpolished side of the marble by himself, saving time and effort. When the surface of the marble is polished, there is still the surface covered by the contact plate 507 that has not been polished. The screw rod 503 can be rotated to lift the contact plate 507 and polish the contact surface separately.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limiting the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. The obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
