Description

Technical Field

[0001] This utility model relates to the field of crystal processing equipment, and in particular to a crystal rough grinding device. Background Technology

[0002] Traditional crystal fine polishing devices operate on the same principle as traditional crystal rough polishing devices: a polishing disc is placed above the crystal holder, and the disc is driven to rotate by a motor to polish the crystal. To ensure the degree of polishing, a lifting mechanism is added to move the polishing disc up and down.

[0003] However, the current fine polishing device has basic problems: 1. The force of the lifting mechanism is not easy to control, which can easily damage the crystal; 2. It is not easy to add water to the polishing surface. Since the polishing disc and the crystal are in full contact, this design has the disadvantage of resulting in poor crystal polishing effect. Utility Model Content

[0004] The purpose of this invention is to provide a crystal polishing device that has the advantages of good polishing effect and simple and convenient operation.

[0005] This utility model is achieved through the following technical solution: a crystal polishing device, characterized in that: it includes...

[0006] The base 1 has a recessed grinding groove 11 on the top;

[0007] Crystal turntable 2 is set in the polishing work tank 11 to hold the crystal and drive the crystal to rotate;

[0008] The turntable drive assembly is located inside the base 1 and passes through the polishing work groove 11 to connect with the crystal turntable 2, thereby driving the crystal turntable 2 to rotate;

[0009] Grinding disc 4 is positioned above crystal turntable 2 and is used to grind the crystal;

[0010] A swing arm 5 is mounted on the base 1, and the grinding disc 4 is detachably mounted on the swing arm 5. The swing arm 5 drives the grinding disc 4 to reciprocate back and forth, achieving regional grinding of the crystal; and

[0011] The swing arm drive mechanism is mounted on the base 1 and connected to the swing arm 5 to drive the swing arm 5 to swing.

[0012] The swing arm 5 includes a horizontal swing arm 51, a vertical swing arm 52, and a vertical limiting frame 53;

[0013] The lateral swing arm 51 is arranged in the left and right direction. The left end of the lateral swing arm 51 is hinged to the base 1 through a vertical shaft provided on the base 1. The right end of the lateral swing arm 51 is connected to the swing arm drive mechanism to realize the reciprocating swing of the lateral swing arm 51 in the front and back direction.

[0014] The vertical swing arm 52 is arranged in a front-to-back direction. A base 54 is provided on the horizontal swing arm 51. The rear end of the vertical swing arm 52 is hinged to the base 54 through a pivot, so that the front end of the vertical swing arm 52 can swing up and down.

[0015] The vertical limiting frame 53 includes a vertical limiting rod 531, at least three connecting frames 532 arranged in a circular array, a limiting wheel rod 533, and a limiting wheel 534. The vertical limiting rod 531 is connected to the front end of the vertical swing arm 52, and the multiple connecting frames 532 are radially connected to the lower end of the vertical limiting rod 531. Each vertical limiting rod 531 is connected to a downwardly extending limiting wheel rod 533, and the lower end of the limiting wheel rod 533 is rotatably connected to the limiting wheel 534. The limiting wheel 534 is attached to the side of the grinding disc 4 to drive the grinding disc 4 to move.

[0016] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0017] 1. This design allows for partial surface contact between the grinding disc and the crystal, facilitating water replenishment and improving the grinding effect. In addition, the grinding disc here uses its own weight to grind the crystal, resulting in relatively even force distribution and good grinding effect. Furthermore, the grinding disc is limited by the limiting wheel, which ensures the accurate position of the grinding disc and also prevents interference from the weight of other parts of the grinding disc.

[0018] 2. The lengths of the horizontal and vertical swing arms are adjustable, making them suitable for polishing crystals of various sizes and specifications.

[0019] 3. The bottom center of the grinding work groove is raised to form a water flow area, thus avoiding the impact of grinding liquid on the shaft hole below the crystal turntable. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings:

[0027] It should be noted that in the description of this utility model, the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figure 1-5 As shown: A crystal rough polishing device, which includes

[0029] The base 1 has a recessed grinding groove 11 on the top;

[0030] Crystal turntable 2 is set in the polishing work tank 11 to hold the crystal and drive the crystal to rotate;

[0031] The turntable drive assembly is located inside the base 1 and passes through the polishing work groove 11 to connect with the crystal turntable 2, thereby driving the crystal turntable 2 to rotate;

[0032] Grinding disc 4 is positioned above crystal turntable 2 and is used to grind the crystal;

[0033] A swing arm 5 is mounted on the base 1, and the grinding disc 4 is detachably mounted on the swing arm 5. The swing arm 5 drives the grinding disc 4 to reciprocate back and forth, achieving regional grinding of the crystal; and

[0034] The swing arm drive mechanism is mounted on the base 1 and connected to the swing arm 5 to drive the swing arm 5 to swing.

[0035] The swing arm 5 includes a horizontal swing arm 51, a vertical swing arm 52, and a vertical limiting frame 53;

[0036] The lateral swing arm 51 is arranged in the left and right direction. The left end of the lateral swing arm 51 is hinged to the base 1 through a vertical shaft provided on the base 1. The right end of the lateral swing arm 51 is connected to the swing arm drive mechanism to realize the reciprocating swing of the lateral swing arm 51 in the front and back direction.

[0037] The vertical swing arm 52 is arranged in a front-to-back direction. A base 54 is provided on the horizontal swing arm 51. The rear end of the vertical swing arm 52 is hinged to the base 54 through a pivot, so that the front end of the vertical swing arm 52 can swing up and down.

[0038] The vertical limiting frame 53 includes a vertical limiting rod 531, at least three connecting frames 532 arranged in a circular array, a limiting wheel rod 533, and a limiting wheel 534. The vertical limiting rod 531 is connected to the front end of the vertical swing arm 52, and the multiple connecting frames 532 are radially connected to the lower end of the vertical limiting rod 531. Each vertical limiting rod 531 is connected to a downwardly extending limiting wheel rod 533, and the lower end of the limiting wheel rod 533 is rotatably connected to the limiting wheel 534. The limiting wheel 534 is attached to the side of the grinding disc 4 to drive the grinding disc 4 to move.

[0039] The swing arm 5 is driven to swing back and forth by a swing arm drive mechanism. Since the grinding disc 4 is mounted on the swing arm, the swing arm can reciprocate back and forth. The crystal to be polished is attached to the crystal turntable 2 with adhesive. By pressing the grinding disc 4 onto the crystal surface, the rotation of the crystal and the reciprocating motion of the grinding disc 4 together complete the polishing of the crystal. During polishing, only manual periodic or automatic water replenishment is required.

[0040] The core of this fine polishing lies in the structure of the vertical limiting frame 53. Specifically, this structure constrains the grinding disc 4 from the side, so as not to interfere with the weight (downward pressure) of the grinding disc 4, while driving the grinding disc 4 to move back and forth with the swing arm.

[0041] Furthermore, the connecting frame 532 is provided with a sliding groove hole 536, the limiting wheel rod 533 passes through the sliding groove hole 534, and locking nuts 535 that cooperate with the limiting wheel rod 533 are provided above and below the sliding groove hole 536, so that the limiting wheel rod 533 is limited to a designated position of the connecting frame 532 by the locking nuts 535.

[0042] Considering the different diameters of the grinding discs 4, in order to ensure that this utility model can fit grinding discs 4 of different diameters, a sliding groove hole 536 is designed to adjust the position of the limiting wheel rod 533.

[0043] The lateral swing arm 51 includes a lateral swing arm main rod 511 and a lateral swing arm adjusting rod 512; the lateral swing arm adjusting rod 512 is sleeved on the right end of the swing arm 5 main rod and can move left and right relative to the lateral swing arm main rod 511.

[0044] The vertical swing arm 52 includes a vertical swing arm main frame 521 and a vertical swing arm adjusting rod 522; the vertical swing arm adjusting rod 522 passes through the front end of the swing arm 5 main frame and can move left and right relative to the vertical swing arm main frame 521; a vertical swing arm locking bolt 523 for locking the vertical swing arm adjusting rod 522 is provided on the swing arm 5 main frame.

[0045] The swing arm 5 here is divided into three parts: a horizontal swing arm 51 that realizes the overall back-and-forth swing; a vertical swing arm 52 that realizes its own up-and-down swing; and a vertical limiting rod 53 that is connected to the grinding disc 4.

[0046] The horizontal swing arm 51 here is provided with a base 54, which is used to rotatably connect to the vertical swing arm 52, so that the front end of the vertical swing arm 52 can swing up and down.

[0047] It should be noted that connecting arms, such as those between the vertical swing arm 52 and the pivot, can be added. Figure 1 , 2 As shown, this is used to improve the connection strength between the two, while also increasing the strength of the vertical swing arm 52 itself.

[0048] This is primarily for adjustment purposes. It's important to note that the main transverse swing arm 51 and the adjusting transverse swing arm 512 can be relatively unfixed, or they can be fixed using locking bolts. This will affect the design of the swing arm drive mechanism, specifically the guide rail 63 within it. If the main transverse swing arm 511 and the adjusting transverse swing arm 512 are relatively unfixed, the guide rail 63 can be a linear guide rail. If the main transverse swing arm 511 and the adjusting transverse swing arm 512 are locked, then the guide rail 63 must be an arc-shaped guide rail.

[0049] When it is necessary to replace the grinding disc 4, simply lift the vertical limit bracket 53, remove the old grinding disc 4, replace it with the new grinding disc 4, and then press down the vertical limit bracket 53. If necessary, the limit wheel rod 533 needs to be adjusted to match different specifications of grinding disc 4.

[0050] The swing arm drive mechanism includes a turntable 61, a rocker arm 62, a guide rail 63, and a turntable motor 64;

[0051] The turntable 61 and guide rail 63 are mounted on the base 1, with the guide rail 63 located to the right of the transverse swing arm adjusting rod 512. A limiting shaft is eccentrically provided on the upper surface of the turntable 61. The front end of the rocker arm 62 is hinged to the limiting shaft, and the rear end of the rocker arm 62 is rotatably connected to a guide rod 65 inserted into the guide rail 63, so that when the turntable 61 rotates, it drives the rocker arm 62 to swing back and forth. The right end of the transverse swing arm adjusting rod 512 is rotatably connected to the guide rod 65. The turntable motor 64 is mounted inside the base 1 and connected to the turntable 61 to drive the turntable 61 to rotate.

[0052] The turntable drive assembly includes a drive motor 31, a drive gear 32, a chain 33, and a transmission gear 34 disposed within the base 1.

[0053] The output shaft of the drive motor 31 is coaxially provided with a drive gear 32, and the transmission gear 34 is coaxially connected to the rotating shaft of the grinding disc 4. The drive gear 32 and the transmission gear 34 are connected by a chain 33 to achieve transmission.

[0054] This transmission method is a conventional technology, so it will not be described in detail.

[0055] The bottom of the grinding work groove 11 is raised in the middle, so that the part of the bottom that is not raised forms a water flow area 111, and the water flow area 111 is provided with drainage holes; the crystal turntable 2 is located above the raised area in the middle.

[0056] Since the anti-friction fluid, which is mainly water, needs to be added during polishing, the bottom center of the polishing working tank 11 is designed to prevent the fluid from flowing out through the shaft hole below the polishing disc 4. Because the crystal rotates during polishing, even if the fluid flows onto the crystal surface, it will be thrown to the side wall of the polishing working tank 11 by centrifugal force, and finally flow into the water flow area 111 and be discharged through the drain hole.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
