Description

Technical Field

[0001] The utility model relates to the technical field of stone processing equipment, in particular to a novel stone ball grinding equipment. Background Art

[0002] The rough stone materials mined from the mountains are processed into building materials after cutting, grinding, chiseling and polishing. These building materials are widely used in engineering construction. These building materials include round stone balls. These round stone balls can not only be used for scenery, but also as isolation ridges or road ridges. These round stone balls are especially suitable for squares, parks and parking lots.

[0003] The Chinese utility model patent with publication number CN204725274U discloses a linkage grinding device for processing multiple circular stone balls at the same time, which helps to improve the production efficiency of grinding stone balls to a certain extent. However, the grinding quality of the grinding device depends on the quality of the arc grinding disc. Once the arc grinding disc is partially worn, it will cause annular lines on the surface of the stone ball, and the entire arc grinding disc needs to be replaced. The replacement frequency of the arc grinding disc is relatively high, resulting in relatively high costs. In addition, in order to facilitate positioning, the grinding device needs to set a cross-section at the bottom of the stone ball, which is not suitable for the grinding of some garden landscapes such as Feng Shui balls; at the same time, in order to be able to grind and shape in one time, the surface area of ​​the arc grinding disc of the grinding device must be greater than half of the surface area of ​​the stone ball, otherwise the top of the stone ball cannot be completely polished and smooth, and manual grinding is still required, and the production efficiency is relatively low.

[0004] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which resulted in this case. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Reference Figures 1 to 3

[0022] A novel stone ball grinding device comprises a frame 1, on which a workbench 2 is arranged, the workbench 2 can move in a vertical direction, a main shaft 21 is fixedly installed on the workbench 2, the main shaft 21 is sleeved with a slider 22 which can slide freely along the main shaft 21, a cylinder 23 is arranged above the main shaft 21, one end of the cylinder 23 is hinged on the slider 22, the other end of the cylinder 23 is hinged on a mounting seat 24, a grinding motor 251, a rotating frame 252 fixedly connected to the output shaft of the grinding motor 251 and a diamond bit 26 detachably connected to the rotating frame 252 are arranged on the mounting seat 24, a first shaft 241 and a second shaft 242 arranged below the first shaft 241 are also fixedly arranged on the mounting seat 24, the other end of the cylinder 23 is hinged on the first shaft 241, one end of the main shaft 21 is hinged on the second shaft 242, a control system is also arranged on the workbench 2, and the control system is communicatively connected with the cylinder 23. Preferably, the grinding surfaces of the diamond bits 26 all face the center of the stone ball 9 .

[0023] Preferably, two bearing sleeves 27 are installed on the workbench 2, and the main shaft 21 is provided with two self-aligning bearings 28, which are installed in the bearing sleeves 27. Because the movement of a part of the structure of the mechanism will affect the movement of other structures accordingly, the precision of each part of the structure is very high, and the use of two self-aligning bearings 27 to install the main shaft 21 can ensure the installation precision of the main shaft 21.

[0024] Preferably, this embodiment includes a positioning device for fixing the stone ball 9, and the positioning structure is installed on the positioning workbench 3 of the stone ball 9 grinding equipment. A rotating disk 30 is rotatably installed on the positioning workbench 3. Before grinding, the stone ball 9 is placed on the rotating disk 30, and the rotating structure of the rotating disk 30 is an existing well-known technology in the field, so it will not be described in detail.

[0025] Further, the positioning structure includes a first roller 31 and at least two second rollers 32, the first roller 31 and each second roller 32 are respectively surrounded outside the lower part of the stone ball 9 and are evenly spaced, and the first roller 31 and each second roller 32 are respectively mounted on the positioning workbench 3 in a rotatable manner, and the first roller 31 is also arranged on the positioning workbench 3 in a manner that can slide inward or outward. Wherein, when the stone ball 9 grinding device is in a working state, the first roller 31 and each second roller 32 are respectively in contact with the lower part of the stone ball 9, so that the first roller 31 and each second roller 32 are respectively arranged around the axis of the rotating disk 30. Wherein, before the stone ball 9 is ground and the stone ball 9 is not positioned, when the stone ball 9 is placed on the rotating disk 30, each second roller 32 has a gap with the lower part of the stone ball 9, and the first roller 31 is in contact with the lower part of the stone ball 9.

[0026] The first roller 31 and the second rollers 32 are of the same size and shape. Figure 3 The stone ball 9 shown.

[0027] The positioning process of the stone ball 9 is as follows: first, the stone ball 9 is placed directly on the rotating disk 30, at which time the stone ball 9 is located in the range surrounded by the first roller 31 and the two second rollers 32, and the circumference of the first roller 31 is tightly against the lower part of the stone ball 9, and then the driving device is started to extend the telescopic rod on the driving device, so that the circumference of the first roller 31 continues to abut against the lower part of the stone ball 9 and applies an inward force, thereby pushing the stone ball 9 to move until the two second rollers 32 respectively abut against the lower part of the stone ball 9, so that the first roller 31 and the two second rollers 32 respectively abut against the lower part of the stone ball 9, thereby realizing the positioning of the stone ball 9.

[0028] Furthermore, the present embodiment also includes a plurality of diamond bits 26 which are sequentially attached to the surface of the arc-shaped grinding disc 4 on the rotating frame 252 from top to bottom, and the curvature of the arc-shaped grinding disc 4 along the transverse section is adapted to the curvature of each diamond bit 26 along the transverse section, so that each diamond bit 26 can fit better with the arc-shaped grinding disc with no gap between them.

[0029] Furthermore, the diamond bit 26 is in a sheet or plate structure and is attached to the arc-shaped grinding disc 4. Specifically, the diamond bit 26 can be fixed by bolts, snaps or adhesives, as long as the two can be detachably connected. In this embodiment, the diamond bit 26 can be removed and replaced separately when replaced, without affecting the use of the arc-shaped grinding disc 4.

[0030] Furthermore, the diamond bit 26 includes a first side 261 and a second side 262, both of which are concave-convex wave-shaped, and the concave-convex wave-shaped is composed of a plurality of wave crests and wave troughs alternatingly, that is, the first side 261 includes a first wave crest 2611 and a first wave trough 2612, and the second side 262 includes a second wave crest 2621 and a second wave trough 2622, the second wave crest 2621 is arranged opposite to the first wave crest 2611, and the second wave trough 2622 is arranged opposite to the first wave trough 2612. When the diamond bit 26 is unfolded, the width along the vertical direction is the same everywhere.

[0031] like Figure 2 As shown, the height of the first wave valley 2612 of the first side edge 261 in the lateral direction (i.e. Figure 2 The position of the middle line segment b) is located at the height (i.e. Figure 2The position of the midline segment a) is below the first wave valley 2612 of the first side 261, so that the first wave valley 2612 of the first side 261 always falls between the two adjacent second wave peaks 2621 of the second side 262, avoiding the appearance of annular lines on the surface of the stone ball 9 during polishing, achieving a non-polished discontinuity on the surface of the stone ball 9, optimizing the product appearance, and improving the aesthetics of the stone ball 9.

[0032] Furthermore, the second side 262 of the upper diamond bit 26 completely overlaps with the first side 261 of the other lower diamond bit 26 and fits tightly together so as to be arranged on the arc-shaped grinding disc 4 by means of threads, snaps or bonding, and the diamond bits 26 are pressed against each other.

[0033] Furthermore, when the diamond bit 26 is unfolded, the cross section along the vertical direction is a parallelogram structure, and two adjacent diamond bits 26 can be stacked together, connected to each other and closed along the side. Specifically, the first side 261 and the second side 262 are both provided with overlapping bevels (first overlapping bevel 2613 and second overlapping bevel 2623), the bevel angle of the first overlapping bevel 2613 is 45 degrees, and the bevel angle of the second overlapping bevel 2623 is -45 degrees. The second overlapping bevel 2623 can perfectly fit with the first overlapping bevel 2613 of the adjacent diamond bit 26. After the diamond bit 26 and the arc-shaped grinding disc 4 are positioned and installed, they are fixed by bolts. Each diamond bit 26 and the arc-shaped grinding disc 4 are locked and not easy to swing or disengage, so as to achieve an overall stable effect.

[0034] Furthermore, the thickness of the diamond segment 26 is 2-10 mm.

[0035] This embodiment avoids the appearance of circular lines on the surface of the stone ball 9 during grinding by setting a concave-convex wavy diamond bit 26; at the same time, each diamond bit 26 is connected to the arc grinding disc 4 by connecting bolts or bonding, and there is no need to frequently replace the arc grinding disc 4, and the cost is relatively low; in addition, a first side edge 261 and a second side edge 262 with overlapping bevels are provided, so that two adjacent diamond bits 26 overlap each other, so that each diamond bit 26 and the arc grinding disc 4 are locked and not easy to swing or separate, and the overall stability effect is achieved. The utility model has a simple and reasonable structure, high strength, uniform force, easy installation, strong stability, and long service life.

[0036] By adopting the above-mentioned design scheme, the beneficial effects of the utility model are as follows: the stone ball 9 grinding equipment of the utility model can replace manual work to complete the grinding process of the stone ball 9, and the production efficiency is relatively high; at the same time, by driving the stone ball 9 to rotate and driving the cylinder 23 to extend and retract to drive the diamond cutter head 26 on the rotating frame 252 to swing in the vertical direction, it is achieved that when the surface area of ​​the arc-shaped grinding disc is small, the entire surface area of ​​the stone ball 9 can be completely covered for grinding, and the grinding quality is relatively high; the wear of the diamond cutter head 26 will not affect the grinding quality, there is no need to frequently replace the diamond cutter head 26, and the cost is relatively low; the rotating support device of the utility model can drive and ensure that during the rotation of the stone ball 9, every position on its surface will pass through the position where the diamond cutter head 26 is located, and the grinding quality is relatively high.
