Description

Technical Field

[0001] The utility model relates to the technical field of diamond processing, in particular to an arc angle grinding device for diamond processing. Background Art

[0002] After synthetic diamonds are cultivated, grown and cut, they need to be roughly ground into shape first, and then polished at multiple angles according to the design. When the prior art grinds and processes diamonds, generally, workers hold a clamping device for clamping diamonds, and then manually control the angle to make the diamonds contact the grinding disc. During the grinding process, the grinding is interrupted multiple times to observe whether the grinding result meets the standard. Therefore, not only the operation is relatively cumbersome, but also the technical requirements for operators are relatively high. Moreover, the high rotation speed of the grinding disc easily causes phenomena such as flying debris and accidental human contact with the grinding disc, resulting in work-related injuries. Therefore, it is necessary to provide a new arc angle grinding device for diamond processing to solve the above technical problems. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides an arc angle grinding device for diamond processing. The utility model can stably realize multi-angle adjustment and grinding of multiple diamonds without the need for workers to hold the operation, greatly improving the operation efficiency and operation safety.

A grinding disc is coaxially arranged inside the protective frame. A plurality of adjusting mechanisms for adjusting the inclination angle of diamonds are equidistantly arranged on the outer wall of the protective frame.

[0005] The adjusting mechanism includes a mounting frame fixedly arranged on the outer wall of the protective frame. A transverse rotating rod is arranged inside the mounting frame, and the transverse rotating rod is in transmission connection with the output end of a transverse motor arranged on the outer wall of the mounting frame.

[0006] The middle section of the transverse rotating rod is bent downward and connected to a support block equipped with a longitudinal motor. One end of the longitudinal rotating rod passes through a preset through hole on the support block and is connected to the output end of the longitudinal motor. The other end is provided with an electric push rod through a limiting plate. The output end of the electric push rod is provided with a clamping mechanism for fixing diamonds.

[0007] Workers can control the corresponding transverse motor and longitudinal motor to work, thereby respectively driving the transverse rotating rod to change the angle of the longitudinal rotating rod relative to the grinding disc. At the same time, the longitudinal rotating rod can drive the diamond to rotate, so as to adjust the contact surface between the diamond and the grinding disc, and then realize multi-angle adjustment of the diamond. Then control the electric push rod to extend, which can drive the clamping head and its diamond to move towards the direction close to the grinding disc. When the diamond abuts against the grinding disc, the grinding operation of the diamond can be realized.

[0008] Preferably, a connecting frame is provided at the output end of the electric push rod, and two supporting rods slidingly penetrating the limit plate are provided on one side of the connecting frame facing the electric push rod, and a supporting bar with a socket at the end is fixedly provided on the other side.

[0009] Preferably, the clamping mechanism comprises a clamping head which is plugged into the plug hole through an insertion rod, and two support plates symmetrically distributed relative to the insertion rod are provided on the outer wall of the clamping head, and a limiting hole is provided inside the support plate;

[0010] The top of the limit rod is plugged into the limit hole, and the bottom is fixedly connected with a connecting piece, and the two connecting pieces are connected to the support bar through an adjusting piece. The clamping head can adopt a structure such as a collet that can clamp and fix the diamond.

[0011] Preferably, the adjusting member comprises a telescopic sleeve with two ends respectively fixedly connected to the supporting bar and the connecting piece, and the exterior of the telescopic sleeve is sleeved with a spring with two ends respectively connected to the supporting bar and the connecting piece.

[0012] Through the setting of the spring, the connecting piece can be effectively kept pushed toward the supporting piece relative to the support bar, thereby ensuring the plug-in state of the limit rod and the support piece, preventing the clamping head from falling off the support bar; later, after completing the grinding process of the diamond, the staff can hold the two connecting pieces opposite to each other to compress the spring again, and the connecting piece drives the limit rod to move out of the limit hole inside the support piece to complete the separation of the clamping head and the support bar.

[0013] Preferably, a grinding motor is provided at the center of the chassis, and the output end of the grinding motor extends into the protective frame and is coaxially connected to the grinding disc.

[0014] Preferably, a suspension frame is provided on the top of the protection frame, and cameras are provided at the inner top of the suspension frame and at the position corresponding to each group of adjustment mechanisms.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] See also Figures 1 to 6 A diamond processing arc angle grinding device comprises a chassis 1 provided with an annular protective frame 11, a grinding disc 2 is coaxially provided inside the protective frame 11, a grinding motor 21 is provided at the center of the chassis 1, an output end of the grinding motor 21 extends into the protective frame 11 and is coaxially connected to the grinding disc 2, a suspension frame 4 is provided on the top of the protective frame 11, and cameras 41 are provided at the inner top of the suspension frame 4 and at the corresponding position of each group of adjustment mechanisms 3.

[0025] A plurality of adjusting mechanisms 3 for adjusting the inclination angle of the diamond are equidistantly arranged on the outer wall of the protection frame 11. The adjusting mechanism 3 includes a mounting frame 31 fixed on the outer wall of the protection frame 11. A transverse rotating rod 32 is arranged in the mounting frame 31, and the transverse rotating rod 32 is in transmission connection with the output end of a transverse motor 321 arranged on the outer wall of the mounting frame 31. The middle section of the transverse rotating rod 32 is bent downward and connected to a support block 332 equipped with a longitudinal motor 331. One end of a longitudinal rotating rod 33 passes through a preset through hole in the support block 332 and is connected to the output end of the longitudinal motor 331, and the other end is provided with an electric push rod 34 through a limiting plate 333. The output end of the electric push rod 34 is provided with a connecting frame 341. On one side of the connecting frame 341 facing the electric push rod 34, there are two support rods 344 slidably penetrating through the limiting plate 333, and on the other side, there is a support strip 342 with a jack 343 opened at the end;

[0026] The clamping mechanism 5 includes a clamping head 51 inserted into the jack 343 through an insertion rod 52. Two support pieces 53 symmetrically distributed relative to the insertion rod 52 are arranged on the outer wall of the clamping head 51. A limiting hole is opened inside the support piece 53. The top end of a limiting rod 531 is inserted into the limiting hole, and the bottom end is fixedly connected to a connecting piece 54. The connecting piece 54 is connected to the support strip 342 through a telescopic sleeve 542, and a spring 541 with two ends respectively connected to the support strip 342 and the connecting piece 54 is sleeved outside the telescopic sleeve 542.

[0027] A control panel 311 is arranged at the top of the mounting frame 31, and the output end of the control panel 311 is in signal connection with the control input ends of the electric push rod 34, the transverse motor 321, the longitudinal motor 331, and the grinding motor 21; the output end of the camera 41 is electrically connected to the input end of an external display screen.

[0028] The working principle of the present utility model is as follows:

[0029] First, the staff can place the diamond to be polished between the chucks of the clamping head 51 (a three-jaw collet or the like can be used), and then tighten the clamping head 51 to fix the diamond.

[0030] Then, move the clamping head 51 to the support strip 342 corresponding to the mounting frame 31. First, overcome the elastic force of the spring 541 to move the two connecting pieces 54 towards each other, so that the distance between the limiting rods 531 on the connecting pieces 54 is reduced. Then, the insertion rod 52 can be inserted into the jack 343. Until the end of the limiting rod 531 corresponds to the limiting hole in the support piece 53, the connecting piece 54 can be released. The spring 541 drives the limiting rod 531 to move away through its own acting force, so that the limiting rod 531 is inserted into the limiting hole of the support piece 53, and the installation of the clamping head 51 can be completed.

[0031] The staff can control the corresponding horizontal motor 321 and vertical motor 331 through the control panel 311 to work, and then drive the horizontal rotating rod 32 respectively to change the angle of the vertical rotating rod 33 relative to the grinding disc. At the same time, the vertical rotating rod can drive the diamond to rotate, so as to adjust the contact surface between the diamond and the grinding disc, and then realize the multi-angle adjustment of the diamond.

[0032] Subsequently, control the electric push rod 34 to extend, which can drive the clamping head 51 and its diamond to move towards the direction close to the grinding disc 2. When the diamond abuts against the grinding disc 2, the grinding operation of the diamond can be realized.

[0033] During the adjustment and grinding process, the staff can view the positional relationship between the diamond and the grinding disc 2 and the instant state of the diamond captured by the camera 41 through the display screen, and then make fine adjustments to the angle and position of the diamond.

[0034] If the grinding debris splashes, it can be blocked by the protective frame 11. At the same time, the staff is at a certain distance from the grinding disc 2, which greatly improves the operation safety.

[0035] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here.

[0036] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
