Description
Technical Field
[0001] This utility model relates to the field of stone processing technology, and in particular to a device for grinding the edges and corners of a billiard table slab. Background Technology
[0002] A billiard table is a table used for playing billiards. It is equipment for competitions and entertainment, and comes in various forms. Each form of entertainment uses different billiard tables and different numbers of billiard balls.
[0003] Billiard tables are mainly composed of wooden frames and stone tabletops. Before use, the stone slabs need to be processed according to their dimensions. Currently, commonly used grinding machines include a support, a conveyor belt, a fixed pressure roller, and a grinding wheel. The stone is placed on the conveyor belt, and the fixed pressure roller applies downward pressure to fix the stone. The edges and corners are ground as the stone passes through the grinding wheel, which greatly improves the efficiency of stone processing. However, during the grinding process, a large amount of stone powder is generated when the grinding wheel grinds the stone. Therefore, this application discloses a device for grinding the edges and corners of billiard table tabletops. Utility Model Content
[0004] The purpose of this invention is to address existing problems by providing a device for grinding the edges and corners of a billiard table slab.
[0005] This utility model is achieved through the following technical solution: a device for grinding the edges of a billiard table slab, including a processing table, on which countersunk holes are evenly distributed, and bullseye shafts are installed in the countersunk holes. A set of edge grinding mechanisms is symmetrically arranged on both sides of the processing table. Each set of edge grinding mechanisms consists of no less than two edge grinding mechanisms. A connecting plate is provided between the edge grinding mechanisms. The outer side of the connecting plate is connected to the telescopic rod of a hydraulic cylinder. The hydraulic cylinder is installed on a wall panel, and the wall panel is connected to a side frame.
[0006] As a further improvement to the above solution, a slide bar is connected below the grinding mechanism, and the slide bar is matched and set inside the slide rail, which is installed on the side frame;
[0007] During the displacement of a set of edge grinding mechanisms driven by the hydraulic cylinder, the slide bar under the edge grinding mechanism slides within the slide rail of the side frame.
[0008] As a further improvement to the above solution, the edge grinding mechanism includes a support frame, with side plates symmetrically arranged inside the support frame. Angle grinding wheels and edge grinding wheels are rotatably arranged on the upper and lower parts of the side plates, respectively. The edge grinding wheels are connected to the output shaft of the lower motor, which is mounted on the outer side of the side plate. The angle grinding wheels are connected to the output shaft of the upper motor, which is mounted on the opposite side plate.
[0009] The lower motor drives the grinding wheel to grind the edges and sides of the stone slab, while the upper motor drives the angle grinding wheel to grind the corners of the stone slab. At the same time, the hydraulic cylinder drives the support frame to adjust the grinding allowance.
[0010] As a further improvement to the above solution, the upper part of the side plate is provided with a through and inclined waist hole, the upper motor is connected to the slide plate, the two sides of the slide plate are clamped between the clamping rails, the clamping rails are installed on the outside of the side plate, and the output shaft of the upper motor is sleeved with a bushing, the bushing is connected to the telescopic rod of the cylinder, and the cylinder is installed at an inclination on the 45° inclined surface of the support frame.
[0011] The cylinder pushes and pulls the bushing, which drives the output shaft of the upper motor to move within the waist hole. The upper motor slides between the rails along with the slide plate to adjust the distance between the grinding wheel and the corner of the stone slab, thereby adjusting the grinding angle size.
[0012] As a further improvement to the above solution, a suction hole is provided through the support frame, and a negative pressure pipe is connected to the outside of the suction hole. The negative pressure pipe is connected to a negative pressure fan, and the negative pressure generated by the operation of the negative pressure fan is used to draw stone powder generated by the grinding wheel between the side plates through the negative pressure pipe.
[0013] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. It uses a hydraulic cylinder to push two edge grinding machines on one side of the processing table close to the edge of the stone slab. The edge grinding wheels grind the side surface of the stone slab, making the side surface flat and smooth, while the angle grinding wheels grind the corner lines of the stone slab, removing the 90° corners of the stone slab. In addition, the stone powder generated during the grinding process of the edge grinding wheels and angle grinding wheels enters the negative pressure pipe through the suction hole, avoiding stone powder splashing and polluting the environment.

[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] like Figures 1 to 3 As shown, a device for grinding the edges of a billiard table slab includes a processing table 1. Countersunk holes 2 are evenly distributed on the processing table 1, and bullseye shafts 3 are installed in the countersunk holes 2. A set of edge grinding mechanisms 10 are symmetrically arranged on both sides of the processing table 1. Each set of edge grinding mechanisms 10 consists of no less than two edge grinding mechanisms 10. A connecting plate 6 is provided between the edge grinding mechanisms 10. The outer side of the connecting plate 6 is connected to the telescopic rod of a hydraulic cylinder 7. The hydraulic cylinder 7 is installed on a wall panel 8, and the wall panel 8 is connected to a side frame 9.

[0020] During the displacement of a set of edge grinding mechanisms 10 driven by hydraulic cylinder 7, the sliding bar 41 under the edge grinding mechanism 10 slides within the inner slide rail 4 of the side frame.
[0021] As a further improvement to the above solution, the edge grinding mechanism 10 includes a support frame 11, with side plates 12 symmetrically arranged inside the support frame 11. Angle grinding wheel 15 and edge grinding wheel 17 are rotatably arranged on the upper and lower parts of the side plates 12, respectively. The edge grinding wheel 17 is connected to the output shaft of the lower motor 18, which is mounted on the outer side of the side plate 12. The angle grinding wheel 15 is connected to the output shaft of the upper motor 14, which is mounted on the opposite side plate 12.
[0022] The lower motor 18 drives the grinding wheel 17 to grind the edge and vertical surfaces of the stone slab, while the upper motor 14 drives the grinding wheel 15 to grind the corners of the stone slab. At the same time, the hydraulic cylinder 7 drives the support frame 11 to adjust the grinding allowance.
[0023] As a further improvement to the above solution, the upper part of the side plate 12 is provided with a waist hole 13 through and inclined. The upper motor 14 is connected to the slide plate 21. The two sides of the slide plate 21 are clamped between the rails 22. The rails 22 are installed on the outside of the side plate 12. The output shaft of the upper motor 14 is sleeved with a bushing 16. The bushing 16 is connected to the telescopic rod of the cylinder 19.

[0026] The working principle of a billiard table slate edge grinding device is as follows: First, the slate is placed on the processing table 1 and supported by the bullseye shaft 3. The hydraulic cylinder 7 pushes two edge grinding machines on one side of the processing table 1 close to the edge of the slate. The edge grinding wheel 17 grinds the side surface of the slate edge to make the side surface flat and smooth, while the corner grinding wheel 15 grinds the corner line of the slate edge to remove the 90° corner of the slate edge. In addition, the stone powder generated during the grinding process of the edge grinding wheel 17 and the corner grinding wheel 15 enters the negative pressure pipe 20 through the suction hole to avoid stone powder splashing and polluting the environment.
