Description

Technical Field

[0001] The utility model relates to the technical field of jade processing, in particular to a gemstone clamping device for drilling jade. Background Art

[0002] To carve a piece of jade into a work of art, a series of processes are required. The jade processing procedure is generally divided into four stages: material selection, design, carving, and polishing. During the processing of gemstones, holes are often drilled in the gemstones by drilling equipment.

[0003] In the prior art, when drilling a hole in a jade article, the gemstone needs to be clamped by a drilling device. The common clamping device has certain disadvantages. When processing annular or disc-shaped gemstones, it is necessary to drill holes on the surface of the annular or disc-shaped gemstones. The clamping device does not clamp the annular or disc-shaped gemstones firmly. The gemstone is placed at the clamping position with only point contact or plane contact, which can easily cause it to loosen. It is particularly troublesome to adjust the clamping device when processing eccentric holes or center holes, and it cannot be guaranteed that the drill bit corresponds to the position of the eccentric hole or the center hole. There is a difference between the processed gemstone and the design drawing. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1 - Figure 4 As shown, a gemstone clamping device for drilling jade comprises a workbench 1, a drill bit 2 and a column 3. The workbench 1 and the drill bit 2 are respectively located at two ends of the column 3, and the drill bit 2 is located directly above the workbench 1. The gemstone to be drilled is placed on the workbench 1 and clamped by a clamping structure 4. The clamping structure 4 is installed on the surface of the workbench 1 and directly below the drill bit 2. The clamping structure 4 comprises two fixing seats 41. The two fixing seats 41 are both arranged on the surface of the workbench 1, and the fixing seats 41 are symmetrically arranged on both sides of the drill bit 2. The gemstone can be placed on the surface of the workbench 1. The insides of the two fixing seats 41 are sequentially provided with knobs 4. 2 and a clamping column 43, the clamping column 43 is screwed into the interior of the knob 42, the knob 42 is placed in the interior of the fixing seat 41, the knob 42 is rotatably connected to the interior of the fixing seat 41, the clamping column 43 is threadedly connected to the interior of the knob 42, when the knob 42 is rotated, the clamping column 43 is threadedly connected to the knob 42, and the clamping column 43 can move horizontally, the ends of the two clamping columns 43 are each provided with a clamping groove 46, the opening directions of the two clamping grooves 46 are arranged oppositely, the side walls of the clamping groove 46 are arc-shaped, the gem is placed in the clamping groove 46 between the two clamping columns 43, so that the position of the clamping column 43 is adjusted to clamp the gem between the clamping grooves 46.

[0024] In this embodiment, the axes of the two clamping columns 43 are aligned with each other, and the planes where the two clamping grooves 46 are located are in a horizontal state. The axis of the drill bit 2 is perpendicular to the planes where the two clamping grooves 46 are located. The gem is placed between the clamping grooves 46. The side walls of the clamping grooves 46 are arc-shaped. The bottom surface of the clamping groove 46 and the side walls of the two clamping grooves 46 form a constraint to ensure that the gem drilling plane is perpendicular to the drill bit 2.

[0025] In this embodiment, a circle of limiting grooves 47 are provided on the cylindrical surface of the knob 42, and a bolt 48 is provided at the top of the fixed seat 41 and at the position of the limiting groove 47, and the end of the bolt 48 is movably connected to the inside of the limiting groove 47; two matching grooves 44 are provided on the cylindrical surface of the clamping column 43, and a matching block 45 is provided inside the fixed seat 41, and the matching block 45 is slidably connected to the inside of the matching groove 44. In order to prevent the position of the clamping groove 46 from rotating, the matching block 45 and the matching groove 44 can slide relative to each other, and the gem placed on the surface of the clamping groove 46 will not be deflected when the knob 42 is rotated.

[0026] In this embodiment, a fitting structure 5 is installed at the end of the clamping column 43 and inside the clamping groove 46. The fitting structure 5 includes two fixed blocks 51, which are respectively welded inside the two clamping grooves 46, and bolts 55 are connected to both sides of the upper and lower surfaces of the fixed blocks 51, and a bending strip 52 is connected inside the fixed block 51 and between the bolts 55. An adjusting bolt 54 is connected to the middle of the bending strip 52, and the end of the adjusting bolt 54 is connected to the fixed block 51. The adjusting bolt 54 is rotated to bend the bending strip 52, and the four corners of the bending strip 52 are used to slide with the end of the bolt 55. The bending strip 52 is in the shape of an arc, and a rubber strip 53 is pasted on the surface of the bending strip 52. The end of the bolt 55 is slidably connected to the two ends of the bending strip 52. At this time, the bending diameter of the bending strip 52 can be changed, gems of different diameters can be clamped, and the bending strip 52 with a changed diameter can fully contact with gems of different diameters.

[0027] When the utility model is in use, the gemstone to be processed is placed on the surface of the workbench 1, and the gemstone is clamped by the clamping column 43 of the clamping structure 4. Specifically, the knob 42 is rotated inside the fixing seat 41, and the bolt 48 is movably connected with the inner part of the limiting groove 47. The knob 42 can be limited by the bolt 48. The knob 42 is in threaded contact with the clamping column 43, and the clamping column 43 moves along its axial direction. The matching block 45 is slidably connected with the matching groove 44 to prevent the position of the clamping groove 46 from being deflected, so that the mutually close gemstones can be fixed. A gem is placed in the clamping groove 46 of the clamping column 43, and the gem is clamped by the clamping groove 46 to ensure that the gem is fixed in the clamping groove 46. The two knobs 42 can be rotated to make the end positions of the clamping column 43 different, and a center hole or an eccentric hole can be drilled on the gem. Since the gem is located at the bending strip 52, the gem can be placed between the bending strips 52 on both sides. The bending strip 52 can adjust the bending of the bending strip 52 according to the diameter of the gem so that the bending strip 52 is in full contact with the gem. The rubber strip 53 prevents the gem from sliding or loosening, and it is less likely to loosen after clamping.
