Technical Field
[0001] The utility model relates to the technical field of crystal grinding, in particular to a crystal ornament grinding machine. Background Art
[0002] Crystal, a rare mineral, a kind of gem, quartz crystal, belongs to the quartz family in mineralogy. Its main chemical component is silicon dioxide with the chemical formula SiO2. When it is pure, it forms colorless and transparent crystals. When it contains trace elements such as Al and Fe, it appears purple, yellow, brown, etc. After irradiation, the trace elements form different types of color centers, producing different colors, such as purple, yellow, brown, pink, etc.
[0003] A Chinese patent disclosed a lens production grinding device with application number CN217255201U, with an application date of April 21, 2022. The patented technology uses the tension of the spring to push two wedge blocks to move back to back at the same time, drive the clamping block to move, and release the clamping block from fixing the mounting block, so as to complete the disassembly of the grinding rod body and facilitate the replacement of the grinding rod. However, the above patent requires the use of two electric push rods to simultaneously drive the clamping components on both sides to move relative or back to back when clamping the lens. The design of the two electric push rods greatly increases the manufacturing cost. Therefore, a person skilled in the art provides a crystal ornament grinding machine to solve the problems raised in the above background technology. Utility Model Content
[0004] The utility model aims to provide a crystal ornament polishing machine, which can fix the crystal ornaments and save the manufacturing cost.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A crystal ornament polishing machine comprises a base, a fixing box is fixedly connected to the top of the base, rotatable bidirectional threaded rods are rotatably connected to the left and right sides of the interior of the fixing box, mirror-symmetrical clamps are threadedly connected to the left and right surfaces of the bidirectional threaded rods, connecting blocks are fixedly connected to the opposite sides of two clamps, and arc plates are fixedly connected to the opposite sides of two connecting blocks; a connecting frame is fixedly connected to the bottom side of the interior of the fixing box, a placement groove is provided on the top of the connecting frame, and a polishing block for polishing crystal ornaments is installed on the top of the connecting frame.
[0007] As a further solution of the utility model: a pair of guide rods are fixedly connected to both sides of the interior of the fixing box, and the guide rods are slidably connected to the clamping plate.
[0008] As a further solution of the utility model: a driven bevel gear is fixedly connected to the middle position of the bidirectional threaded rod, a driving bevel gear is arranged at the front end of the bidirectional threaded rod, the driving bevel gear is vertically meshed with the driven bevel gear, and a rotating rod is fixedly connected to the front side of the driving bevel gear.
[0009] As a further solution of the utility model: a ratchet is fixedly connected to the front side of the rotating rod, and a reversible ratchet is installed on the left side of the ratchet; a positioning plate is fixedly connected to the front side of the fixed box, a top support plate is fixedly connected to the bottom left side of the positioning plate, and fixing plates are fixedly connected to the front and rear sides of the bottom of the positioning plate respectively, and the two fixing plates have connecting rods fixedly connected to the opposite sides, the connecting rod is rotatably connected to the ratchet, and a support spring is fixedly connected to the rear side of the ratchet, and the left side of the support spring is fixedly connected to the positioning plate.
[0010] As a further solution of the utility model: a group of hollow tubes are fixedly connected to the top of the fixed box, and the interior of the hollow tubes is slidably connected to an extension, and a flat plate that can move up and down is fixedly connected to the top of a group of extension rods, and a motor is fixedly connected to the top of the flat plate, and the output end of the motor is fixedly connected to the grinding block.
[0011] As a further solution of the utility model: a gear is fixedly connected to the left side of the bidirectional threaded rod, a toothed plate is meshed on the rear side of the gear, and the top of the toothed plate is fixedly connected to the plane plate.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The crystal ornament polishing machine is configured by placing the crystal ornament on the surface of the placement groove with the polished end of the crystal ornament facing upwards, and rotating the rotating rod clockwise. The rotating rod drives the two-way threaded rod to rotate clockwise through the cooperation of the active bevel gear and the driven bevel gear, thereby driving the two clamping plates to move toward each other until the two arc blocks clamp the two ends of the crystal ornament. When the two-way threaded rod rotates clockwise, it drives the gear to rotate clockwise, thereby driving the toothed plate to move downward, thereby driving the flat plate and the polishing block to move downward, and at the same time, the extension rod slides along the inside of the hollow tube to guide the flat plate and the polishing block when they move. When the two arc blocks clamp the crystal ornament, the polishing gauze paper at the bottom of the polishing block contacts the top surface of the crystal ornament. The cooperation of the above structure can save manufacturing costs while also fixing the crystal ornament.
[0014] In addition, when the rotating rod of the crystal ornament polishing machine rotates clockwise, the arc surface of the ratchet contacts the ratchet teeth, thereby driving the ratchet teeth to flip over and at the same time driving the supporting spring to deform. When the ratchet teeth pass the rear support spring, the ratchet teeth return to their original position. When the ratchet rotates counterclockwise, the ratchet teeth abut against the protruding end surface of the ratchet wheel, thereby limiting the counterclockwise rotation of the ratchet wheel, thereby limiting the rotation of the rotating rod. After the crystal ornament is polished, pull the ratchet teeth to the left to separate the ratchet teeth from the surface of the ratchet wheel, thereby allowing the rotating rod to break away from the rotation restriction. Then rotate the rotating rod counterclockwise to allow the two splints to move away from each other and break away from the clamping and fixing of the crystal ornament.

DETAILED DESCRIPTION
[0021] like Figure 1 , 2 As shown in Figure 4, a crystal ornament polishing machine includes a base 10, a fixing box 11 is fixedly connected to the top of the base 10, the interior of the fixing box 11 is hollow and the top is open, a rotatable bidirectional threaded rod 20 is rotatably connected to the left and right sides of the interior of the fixing box 11, and a mirror-symmetrical splint 21 is threadedly connected to the left and right side surfaces of the bidirectional threaded rod 20.
[0022] Preferably, guide rods 22 are provided on the front and rear sides of the fixing box 11, and the left and right sides of the two guide rods 22 are fixedly connected to the left and right sides of the fixing box 11. The guide rods 22 are slidably connected to the clamping plate 21, thereby achieving a guiding effect when the clamping plate 21 moves.
[0023] Specifically, refer to Figure 2 , 4 A connection frame 23 is fixedly connected to the middle position of the inner bottom side of the fixed box 11. The left and right through holes of the connection frame 23 are used to stagger the position of the bidirectional threaded rod 20. A driven bevel gear 24 is fixedly connected to the middle position of the bidirectional threaded rod 20. A driving bevel gear 25 is provided at the front end of the bidirectional threaded rod 20. The driving bevel gear 25 is vertically meshed with the driven bevel gear 24. A rotating rod 26 is fixedly connected to the front of the driving bevel gear 25. The rotating rod 26 extends forward and is rotatably connected to the connection frame 23 and the surface of the fixed box 11 respectively. A placement groove 27 is provided on the top of the connection frame 23. When in use, the crystal ornament is placed on the surface of the placement groove 27, and the polished end of the crystal ornament faces upward.
[0024] Preferably, the opposite sides of the two splints 21 are fixedly connected with connecting blocks 30, and the opposite sides of the two connecting blocks 30 are fixedly connected with arc plates 31. When in use, by rotating the rotating rod 26 clockwise, the rotating rod 26 drives the bidirectional threaded rod 20 to rotate clockwise through the cooperation of the active bevel gear 25 and the driven bevel gear 24, thereby driving the two splints 21 to move toward each other until the two arc plates 31 clamp the two ends of the crystal ornament.
[0025] Since the above structure does not limit the rotating rod 26, when the crystal ornament is polished, the rotating rod 26 is likely to cause the bidirectional threaded rod 20 to rotate, thereby causing the arc plate 31 to be loosely clamped and affecting the polishing; therefore, a limiting mechanism is proposed.
[0026] refer to Figure 1 , 5A ratchet 40 is fixedly connected to the front side of the rotating rod 26, and a reversible ratchet 41 is installed on the left side of the ratchet 40; a positioning plate 42 is fixedly connected to the front side of the fixed box 11, and a top support plate 43 is fixedly connected to the left side of the bottom of the positioning plate 42, and fixing plates 44 are fixedly connected to the front and rear sides of the bottom of the positioning plate 42 respectively, and the two fixing plates 44 have connecting rods 45 fixedly connected on opposite sides, and the connecting rods 45 are rotatably connected to the ratchet 41, and a support spring 46 is fixedly connected to the rear side of the ratchet 41, and the left side of the support spring 46 is fixedly connected to the positioning plate 42. When the rotating rod 26 rotates clockwise, the arc surface of the ratchet 40 contacts the ratchet 41, thereby driving the ratchet 41 to flip and simultaneously driving the support spring 46 to deform. When the ratchet 41 passes over, the support spring 46 drives the ratchet 41 to return to its original position. When the ratchet 40 rotates counterclockwise, the ratchet 41 abuts against the protruding end surface of the ratchet 40, thereby limiting the counterclockwise rotation of the ratchet 40, thereby limiting the rotation of the rotating rod 26. After the crystal ornaments are polished, the ratchet 41 is pulled leftward to separate the ratchet 41 from the surface of the ratchet 40, thereby allowing the rotating rod 26 to break away from the rotation restriction. The rotating rod 26 is then rotated counterclockwise, thereby allowing the two clamping plates 21 to move away from each other and break away from the clamping and fixing of the crystal ornaments.
[0027] refer to Figure 2 , 3 The four corners of the top of the fixed box 11 are fixedly connected with hollow tubes 50, and the extension rods 51 are slidably connected inside the hollow tubes 50. A flat plate 52 is fixedly connected to the top of a group of extension rods 51, and a motor 53 is fixedly connected to the top of the flat plate 52. A grinding block 54 is fixedly connected to the output end of the motor 53, and a grinding paper (not shown in the figure) is arranged at the bottom of the grinding block 54. A gear 55 is fixedly connected to the left side of the bidirectional threaded rod 20, and a toothed plate 56 is meshed with the rear side of the gear 55, and the top of the toothed plate 56 is fixedly connected to the flat plate 52. When the bidirectional threaded rod 20 rotates clockwise, it drives the gear 55 to rotate clockwise, thereby driving the tooth plate 56 to move downward, thereby driving the flat plate 52 and the grinding block 54 to move downward, and at the same time, the extension rod 51 slides along the inside of the hollow tube 50 to guide the flat plate 52 and the grinding block 54 when they move. When the two arc plates 31 clamp the crystal ornaments, the grinding paper at the bottom of the grinding block 54 contacts the top surface of the crystal ornaments, and then the motor 53 is started by an external power supply, and the output end of the motor 53 drives the grinding block 54 to rotate, thereby grinding the crystal ornaments.
[0028] The working principle of the utility model is as follows: when in use, the crystal ornament is placed on the surface of the placement groove 27, with the polished end of the crystal ornament facing upward, and the rotating rod 26 is rotated clockwise, and the rotating rod 26 drives the two-way threaded rod 20 to rotate clockwise through the cooperation of the active bevel gear 25 and the driven bevel gear 24, thereby driving the two clamping plates 21 to move toward each other until the two arc plates 31 clamp the two ends of the crystal ornament. When the two-way threaded rod 20 rotates clockwise, it drives the gear 55 to rotate clockwise, thereby driving the toothed plate 56 to move downward, thereby driving the plane plate 52 and the polishing block 54 to move downward, and at the same time, the extension rod 51 slides along the inside of the hollow tube 50 to guide the plane plate 52 and the polishing block 54 when they move. When the two arc plates 31 clamp the crystal ornament, the polishing gauze paper at the bottom of the polishing block 54 contacts the top surface of the crystal ornament.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
