Description

Technical Field

[0001] This application relates to the field of stone polishing platform technology, specifically to a multifunctional stone polishing platform. Background Technology

[0002] With the acceleration of industrialization, the stone processing industry has increasingly higher requirements for stone surface treatment. Traditional stone grinding equipment generally suffers from low grinding efficiency and inconvenient operation, especially in the clamping and replacement of stone slabs. Traditional equipment often requires manual operation, resulting in unstable clamping force and easy loosening or damage to the stone slabs. In addition, stone surface treatment often requires frequent changes of clamping surfaces, which traditional equipment cannot easily and quickly switch between, leading to interruptions in the grinding process, increasing production cycles and costs.

[0003] To improve the efficiency and quality of stone polishing, stone polishing platforms need to possess multiple functions, including stable clamping of stone slabs, quick changing of clamping surfaces, and flexible adjustment of clamping force. Existing technologies struggle to simultaneously meet these requirements; therefore, a multifunctional stone polishing platform is needed that can enhance stone polishing results, increase production efficiency, and offer convenient operation. Summary of the Invention

[0004] In view of the above-mentioned technical problems, this application solves the problem that it is inconvenient to replace the stone clamping surface in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a multifunctional stone polishing platform, comprising a polishing platform, a main shaft rotatably mounted on the polishing platform, a turntable and an upper limiting plate fixedly mounted on the main shaft, the turntable being rotatably connected to the polishing platform, a drive rod rotatably mounted on the main shaft, a push rod slidably mounted on a groove on the drive rod, a support plate fixedly mounted on the push rod, a lower limiting plate slidably mounted on the main shaft, and multiple protrusions mounted on both the lower and upper limiting plates, the protrusions on the lower and upper limiting plates being interleaved.

[0006] To better realize this application, a limit plate is further fixedly provided on the grinding platform, the push rod is slidably connected to the limit plate, an upper spring is fixedly provided on the limit plate, and the upper spring is fixedly connected to the drive rod.

[0007] To better realize this application, a control rod is rotatably mounted on the push rod, and a control shaft is rotatably mounted on the control rod. The end of the control shaft near the grinding platform is slidably connected to the slide groove of the grinding platform.

[0008] To better realize this application, a connecting plate is further slidably disposed on the main shaft, and a lower spring is fixedly disposed on the connecting plate, the lower spring being fixedly connected to the lower limiting plate.

[0009] To better realize this application, a connecting rod is rotatably provided on the grinding platform, the connecting rod is rotatably connected to the connecting plate, and a foot pedal is fixedly provided on the connecting rod.

[0010] To better realize this application, the support plate is further provided with a flexible material.

[0011] The technical solution provided in this application has the following advantages compared with the prior art:

[0012] 1. This application provides a stable clamping device that prevents the stone slab from loosening or shifting during the polishing process, ensuring the stability of the polishing process and thus improving work efficiency and polishing quality.

[0013] 2. Through the design of the control axis, this application allows operators to quickly and easily change the clamping surface of the stone slab, reducing the time required for changing surfaces and improving production efficiency.

[0014] 3. The support plate of this application uses flexible materials (such as rubber), which effectively avoids damage to the surface of the stone slab caused by hard contact, protects the appearance of the stone slab, and ensures the production quality of the stone.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] like Figures 1 to 4 As shown, a multifunctional stone polishing platform includes a polishing platform 101. A main shaft 103 is rotatably mounted on the polishing platform 101. A turntable 102 and an upper limiting plate 112 are fixedly mounted on the main shaft 103. The turntable 102 is rotatably connected to the polishing platform 101. A drive rod 104 is rotatably mounted on the main shaft 103. A push rod 107 is slidably mounted on a groove on the drive rod 104. A support plate 108 is fixedly mounted on the push rod 107. A lower limiting plate 113 is slidably mounted on the main shaft 103. Both the lower limiting plate 113 and the upper limiting plate 112 are provided with multiple protrusions, and the protrusions on the lower limiting plate 113 and the upper limiting plate 112 are interleaved.

[0025] Specifically, each end of the drive rod 104 has a groove, and a push rod 107 is slidably mounted on each groove. The two push rods 107 slide laterally on the limiting plate 106, which restricts the sliding of the push rods 107. The width of the support plate 108 on the push rod 107 is the same as the distance between the two push rods 107. Therefore, when the push rod 107 pulls the support plate 108 to clamp the stone slab 118, the clamping point will not be offset due to the small size of the two support plates 108. That is, the line connecting the two clamping points will be an inclined straight line instead of a straight line horizontal to the push rod 107. In this case, the two support plates 108 will cause the stone slab 118 to rotate around the axis of the main shaft 103, thus affecting the polishing of the stone slab 118. Therefore, the width of the support plate 108 needs to be the same as the distance between the two push rods 107, and the distance between the two push rods 107 needs to be restricted by the limiting plate 106 to keep it constant.

[0026] like Figure 4As shown, a limiting plate 106 is fixedly installed on the grinding platform 101, and the push rod 107 is slidably connected to the limiting plate 106. An upper spring 105 is fixedly installed on the limiting plate 106, and the upper spring 105 is fixedly connected to the drive rod 104.

[0027] A control rod 110 is rotatably mounted on the push rod 107, and a control shaft 111 is rotatably mounted on the control rod 110. The end of the control shaft 111 near the grinding platform 101 is slidably connected to the groove of the grinding platform 101.

[0028] Specifically, when it is necessary to clamp the stone slab 118 or change the clamping surface of the stone slab 118, such as... Figure 4 In the indicated state, the control shaft 111 is manually controlled or pushed via an external electric cylinder, causing it to slide on the groove of the grinding platform 101. This, in turn, pushes the push rod 107 onto the limit plate 106 via the control rod 110, causing the support plate 108 on the push rod 107 to move away from the main shaft 103. The push rod 107 also pulls the groove at one end of the drive rod 104, causing the drive rod 104 to rotate on the main shaft 103. Because the upper limit plate 112 on the main shaft 103 is restricted by the lower limit plate 113, the rotation of the drive rod 104 does not cause the main shaft 103 to rotate. It will also twist the upper spring 105 on the limit plate 106. When the support plates 108 on both sides move a long distance, the stone plate 118 is placed in and supported by the main shaft 103. Alternatively, the direction of the stone plate 118 can be rotated to change the clamping surface. Then, the control shaft 111 is reset, so the push rod 107 loses its thrust. Under the action of the upper spring 105, the drive rod 104 is reset. Then, the two push rods 107 and the support plate 108 are reset through the sliding grooves at both ends of the drive rod 104, so that they are in contact with the stone plate 118. The elastic force of the upper spring 105 keeps the contact between the support plate 108 and the stone plate 118 tight.

[0029] like Figure 3 As shown, a connecting plate 115 is slidably disposed on the main shaft 103, and a lower spring 114 is fixedly disposed on the connecting plate 115. The lower spring 114 is fixedly connected to the lower limiting plate 113.

[0030] A connecting rod 116 is rotatably mounted on the grinding platform 101. The connecting rod 116 is rotatably connected to the connecting plate 115. A foot pedal 117 is fixedly mounted on the connecting rod 116.

[0031] Specifically, when a new stone slab 118 needs to be placed for polishing, the worker steps on the foot pedal 117, causing the connecting rod 116 to rotate on the polishing platform 101. This, in turn, causes the connecting plate 115 to slide upward on the main shaft 103. The elastic force of the lower spring 114 pushes the lower limiting plate 113 into close contact with the upper limiting plate 112, and the protrusion on the lower limiting plate 113 inserts between two adjacent protrusions on the upper limiting plate 112. This achieves the restriction of the lower limiting plate 113 on the upper limiting plate 112, that is, the restriction of the rotation of the main shaft 103. Thus, when the control shaft 111 is pushed to move, the rotation of the drive rod 104 will not drive the main shaft 103 to rotate due to friction.

[0032] When the clamping surface of the stone slab 118 needs to be replaced, the worker releases the foot pedal 117, allowing the connecting plate 115 to slide downwards on the main shaft 103 under gravity. This, in turn, causes the lower limiting plate 113 to slide downwards on the main shaft 103 via the lower spring 114. Consequently, the lower limiting plate 113 disengages from the upper limiting plate 112, no longer restricting the upper limiting plate 112, and therefore no longer restricting the rotation of the main shaft 103. At this point, the rotation of the turntable 102 can be controlled, thereby driving the main shaft 1... 03 rotates on the grinding platform 101, which in turn drives the stone slab 118 on the main shaft 103 to rotate. Before rotating the turntable 102, the control shaft 111 needs to be pushed to move the two support plates 108 away from the stone slab 118. Then, the control turntable 102 rotates to change the clamping surface of the stone slab 118. Then, the control shaft 111 is released, and the support plates 108 contact the stone slab 118 again, thus realizing the replacement of the clamping surface of the stone slab 118, which facilitates stable grinding and quick reversal when grinding the stone slab 118.

[0033] like Figure 3 and Figure 4 As shown, a flexible material 109 is provided on the support plate 108. Specifically, the flexible material 109 is preferably a rubber material, so as to better protect the stone slab 118 and avoid damage to the appearance of the stone slab 118 and affect the production quality due to hard contact with the stone slab 118.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
