Description

Technical Field

[0001] The utility model relates to the field of diamond polishing, in particular to a dustproof structure for diamond polishing and polishing equipment using the dustproof structure. Background Art

[0002] During the production process, diamonds need to be ground and polished before they can be processed further. Figure 1 As shown, the diamond is glued to the bottom of the copper rod 1' with glue, and the clamping device 2' clamps the copper rod 1' on the rotating grinding wheel 3' for polishing. This device has the following two problems:

[0003] First, although the glue used for bonding is high-temperature resistant, friction will be generated during the polishing process. If the bonding is improper or the temperature rises too quickly, causing the dissolution, the diamond will detach from the copper rod 1' and fly out. Since diamonds are hard but relatively brittle, the device effectively prevents diamonds from breaking due to collisions during operation by installing an annular rubber ring 4' on the outer periphery of the grinding disc 3'. However, picking up the diamonds is extremely troublesome, and the equipment must be completely shut down and the annular rubber ring 4' must be removed before the diamonds can be picked up. If the diamonds are directly fixed by clamping rather than bonding, although it can prevent the diamonds from detaching from the copper rod 1' and flying out, the clamping method has certain requirements on the size of the clamped diamonds, which is limited.

[0004] Second, a large amount of dust will be generated during the grinding process of the diamond and the grinding disc 3'. The device sets a dust removal hole in the cavity of the motor that drives the grinding disc 3' to rotate, and connects the dust collector through the dust removal hole to remove dust. However, some dust will still float above the grinding disc 3'.

[0005] In order to solve the dust problem generated during the grinding process, the applicant proposed a "dust-proof device for a diamond grinding device" with patent application number 202122822682.2. The dust-proof device is a dust cover arranged above the grinding disc. The dust cover isolates the ground dust from the outside. This device can reduce the dust from floating above the grinding disc 3' and improve the dust removal efficiency. However, the diamonds that fall into the dust cover need to be taken out after the dust cover is removed. After the diamonds are taken out, the dust cover is installed again to continue the polishing work. The whole process also needs to be repeatedly turned on and off. Therefore, further improvements are needed. Utility Model Content

[0006] The first technical problem to be solved by the present invention is to provide a dust-proof structure for conveniently picking up diamonds that fall off during the grinding process in response to the above-mentioned existing technical status.

[0007] The second technical problem to be solved by the utility model is to provide a polishing and grinding device with the dustproof structure.

[0008] The utility model solves the above first technical problem adopts the technical scheme: this dustproof structure for diamond polishing and grinding, including cover body, the cover body includes top wall and the vertical downward extension of annular peripheral wall from the outside edge of top wall, the annular peripheral wall is connected with top wall to form the cavity, the cavity can at least partially surround the grinding disc for grinding diamond, characterized by: the top wall of cover body is equipped with the first opening that can supply diamond to extend into the cavity, the annular peripheral wall is partially provided with the second opening and the switch spare that can open and close the second opening, in the state that the switch spare opens the second opening, the operating personnel can pick up the diamond that falls off in the grinding process from the second opening.

[0009] In order to facilitate opening and closing the second opening, further, the inside edge of annular peripheral wall extends a circle of convex edge inward, the convex edge and / or top wall is provided with the guide portion that can move along the circumference of the switch spare. The intention of this convex edge design is: by virtue of convex edge can more stably rest in the periphery of grinding disc, to play a better dustproof effect, in addition, the convex edge can also be provided with the guide portion for switch spare movement, the guide portion can be groovy or rail-like, to make switch spare more smoothly rotate along the "annular" circumference of cover body, of course, it can also be other directions, setting in "annular" circumference is only more simple when setting.

[0010] Further, the second opening is constituted by the gap between the top wall and the convex edge, and the switch spare is constituted by the switch part of at least partially nested inside and outside. Each switch part constitutes the annular peripheral wall in the closed state. Since the dustproof structure is arranged in the center of each polishing and grinding station, as described above, the diamond is easily "splashed" and restrained in the cavity of the cover body during the polishing and grinding process. Therefore, the falling position of the diamond is any position on the "annular" circumference of the cover body. The key design of the application is to design the second opening as a full open space along the gap between the top wall and the convex edge. Correspondingly, the switch spare can be opened or closed in any direction. The preferred design of nested inside and outside can avoid interference with the operating personnel picking up the diamond due to the setting of the grinding station.

[0011] In order to facilitate the movement of each switch part by the operating personnel, further, each switch part is respectively provided with a handle that can be exposed outside the top wall. In this way, the operating personnel can move each switch part by holding the handle.

[0012] Furthermore, four first openings are provided to correspond to four grinding stations, and the opening section of each first opening corresponds to the travel distance required for diamond grinding. The number and position of the first openings correspond to the grinding stations, and the travel distance required for diamond grinding is reserved. In this way, during the grinding process, the diamond will not be affected by the need to extend into the cavity of the cover.

[0013] To solve the second technical problem, the utility model provides a polishing device, including a workbench for grinding, a grinding disc for grinding diamonds is arranged in the center of the workbench, and the grinding disc is covered by a dustproof structure, characterized in that: the dustproof structure is a cover body as defined above.

[0014] Furthermore, a limiting groove is provided on the outer periphery of the grinding disc, and the cover body surrounds the grinding disc by embedding the convex edge into the limiting groove.

[0015] Compared with the prior art, the advantages of the present invention are: the dust-proof cover uses its annular circumferential wall to confine the diamonds splashed during the polishing process in the cavity of the cover, and a second opening and a switch member that can open and close the second opening are partially opened on the annular circumferential wall. When the switch member opens the second opening, the operator can pick up the diamonds that fall off during the grinding process from the second opening. The entire picking process is convenient and fast. There is no need to repeatedly turn the equipment on and off, and there is no need to remove the dust-proof structure to pick up the diamonds, which is highly efficient. When the dust-proof cover is combined with the polishing equipment, it can provide a relatively stable dust-proof effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] like Figure 2-9 The figure shows a preferred embodiment of the present invention. The polishing equipment in this embodiment includes a workbench 6 for grinding, four grinding stations 8 are arranged around the workbench 6, and a grinding disc A for grinding diamonds is arranged in the center of the workbench 6. A dustproof structure is also provided on the grinding disc A. The dustproof structure includes a cover body B, which includes a top wall 1 and an annular peripheral wall 3 extending vertically downward from the outer edge of the top wall 1. The annular peripheral wall 3 is joined to the top wall 1 to form a cavity 4. The cavity 4 can at least partially surround the grinding disc A for grinding diamonds. In addition, the top wall 1 of the cover body B is provided with a first opening 11 for allowing diamonds to extend into the cavity 4. The annular peripheral wall 3 is partially provided with a second opening 31 and a switch 32 for opening and closing the second opening 31. When the switch 32 opens the second opening 31, an operator can pick up diamonds that fall off during the grinding process from the second opening 31. The cover B utilizes its annular peripheral wall 3 to confine diamonds that fly off during the polishing process within the housing 4 of the cover B. A second opening 31 and a switch member 32 capable of opening and closing the second opening 31 are partially opened on the annular peripheral wall 3. When the switch member 32 opens the second opening 31, an operator can pick up diamonds that fall off during the polishing process from the second opening 31. The entire picking process is convenient and quick, and there is no need to repeatedly turn the equipment on and off, nor to remove the dustproof structure, to pick up diamonds, thereby achieving high efficiency.

[0027] Specifically, the grinding rod in each grinding station 8 extends into the cover B through the first opening 11 formed in the top wall 1 and is ground by the grinding disc A, and since the opening section of each first opening 11 corresponds to the required travel distance of the diamond in grinding, in addition, the first opening 11 is in fluid communication with the bottom opening of the cover B to form an air flow channel from top to bottom, so that the phenomenon of centrifugal splashing of the easily "splashed" diamond during polishing is further avoided.

[0028] In addition, the inner edge of the annular peripheral wall 3 of the cover B extends inwardly by a protruding edge 2, and the protruding edge 2 and the top wall 1 are both provided with a guide portion 5 for the movement of the switch member 32 in the circumferential direction. The protruding edge 2 is designed to be stably placed on the periphery of the grinding disc A to better prevent dust. In addition, the protruding edge 2 is also provided with a guide portion 5 for the movement of the switch member 32, which can be in the form of a groove or a guide rail. In this embodiment, a first track 51 and a second track 52 are arranged inside and outside to make the switch member 32 rotate more smoothly along the "annular" circumferential direction of the cover B. In addition, in order to more stably realize the covering of the cover B, a limiting groove 7 is arranged on the outer periphery of the grinding disc A, so that the cover B can surround the grinding disc A by embedding the protruding edge 2 into the limiting groove 7.

[0029] As mentioned above, the diamond is easily "splashed" during polishing and is restrained in the cavity 4 of the cover B by the annular peripheral wall 3. Therefore, the falling position of the diamond is at any position in the "annular" circumferential direction of the cover B. A key design of the present application is that the second opening 31 is formed by the gap between the top wall 1 and the protruding edge 2, and the switch member 32 is composed of switch parts arranged at least partially inside and outside each other. Each switch part forms the annular peripheral wall 3 in the closed state. Since the dustproof structure is arranged in the center of each polishing station, the second opening 31 is designed as a full open space along the gap between the top wall 1 and the protruding edge 2, and correspondingly, the switch member 32 can be a combination of switch parts that can be opened or closed in any direction, preferably in the form of inside and outside stacking, such as the first switch part 321 and the second switch part 322 in the form of a semicircular arc in this embodiment. The first switch part 321 and the second switch part 322 form the annular peripheral wall 3 in the closed state and can be opened and closed at any position in the circumferential direction along the guide portion 5 to avoid interference of the operating personnel with the picking of the diamond due to the arrangement of the grinding station 8. Finally, in order to facilitate the movement of the operating personnel to move each switch part, a handle 323 is arranged on the first switch part 321 and the second switch part 322 to be exposed outside the top wall. In this way, the operating personnel can move each switch part by holding the handle 323.

[0030] In summary, the dust-proof structure is set on the polishing equipment in the following way: the diamond to be ground is extended into the corresponding first opening 11 by means of the grinding rod and is contacted with the grinding disc A in the cavity 4 for grinding. During the grinding process, if any diamond falls off, it will be constrained in the cavity 4 of the cover body B. The operator only needs to move the first switch part 321 or the second switch part 322 or open and close the first switch part 321 and the second switch part 322 at the same time. When the second opening 31 is opened, the operator can pick up the diamond that falls off during the grinding process from any position around the cover body B, and then the first switch part 321 or the second switch part 322 closes the second opening 31, re-bonds the fallen diamond, and continues the grinding operation without stopping the machine.
