Abstract
The utility model relates to a clamping device for a pearl drilling machine. In the technical scheme, an inner core is additionally arranged in a clamping component, and a central hole is arranged in the inner core. Therefore, only the inner core needs to be replaced when a punching needle and the central hole are worn during processing, thereby saving the cost; the inner core is coupled with the clamping component through external threads arranged on one end of the inner core, thereby making the replacement convenient and rapid; and the clamping component is provided with 3-9 clamping grooves on the end near the threads of the inner core, thereby realizing further clamping of the inner core based on the threaded connection, and making the positioning more accurate. The utility model has the advantages of simple structure, accurate positioning and low cost, and is applicable to the drilling and positioning of round work pieces such as pearls.
Description
Technical field
The utility model relates to a kind of clamping device, especially a kind of clamping device that is used on the pearl puncher.
Background technology
Clamping device on the existing pearl puncher is to utilize to hold one to one to be provided with the holder of deep-slotted chip breaker with the pearl clamping, select corresponding holder according to the size of processing pearl, the center of holder has central through hole, add the holder of arranging relatively man-hour two pearl is clamped, perforating needle punches to pearl by the centre bore of holder.The pearl hole of this method processing is difficult for departing from the center, and crudy is good, but after perforating needle and centre bore repeatedly wear and tear, makes centre bore become big, and the accuracy of influence location needs holder integral body is changed, and makes the cost increase.
Summary of the invention
The purpose of this utility model is that design is kind simple in structure, accurate positioning, cost are low is used for clamping device on the pearl puncher.The technical solution of the utility model is so to realize:
A kind of clamping device that is used on the pearl puncher comprises the inner holder of being with centre bore, and an end of holder is provided with the arc groove, is provided with an inner core in the described holder, and centre bore is located at interior in-core, and inner core connects with holder by the external screw thread of being located at the one end.
As preferably, an end of described holder is provided with clamping slot.
As preferably, the number of described clamping slot is 3～9.
As preferably, the outer end of described inner core is provided with the mounting plate of two symmetries.
The utility model design be used for clamping device on the pearl puncher, be to have set up an inner core in the inside of holder, centre bore is located at interior in-core, and this just makes that directly only changing inner core after perforating needle and centre bore wear and tear in the process gets final product, and has saved cost; Inner core connects with holder by the external screw thread of being located at the one end, makes that replacing is convenient and swift; Nearly inner core screw thread one end is provided with 3-9 clamping slot on the holder, can further clamp inner core on the basis that is threaded, and makes that the location is more accurate.The utlity model has simple in structure, accurate positioning, characteristics that cost is low.Use the punching location that is suitable for round pieces such as pearl.
1, compare with pearl punching chuck in the prior art, the utility model adopts the inner core of hard material to add the structural design of holder, has improved its service life greatly.
2, be suitable for the use of many specification punching chucks, existing only the need carried out the specification adjustment to the clamping inner core, to satisfy the needs of different size pearl punching, improved manufacturing efficient, reduced the cost of clamping device.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is cutaway views of the present utility model;
Accompanying drawing 3 is right views of accompanying drawing 1.
The specific embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: with reference to the accompanying drawings 1, accompanying drawing 2, accompanying drawing 3, a kind of clamping device that is used on the pearl puncher, the holder 1 that comprises inner band centre bore 2, one end of holder 1 is provided with arc groove 3, be provided with an inner core 5 in the described holder 1, centre bore 2 is located in the inner core 5, and inner core 5 connects with holder 1 by the external screw thread 6 of being located at the one end.The outer end of inner core 5 is provided with the mounting plate 8 of two symmetries.One end of holder 1 is provided with 6 clamping slots 7.
During use, earlier inner core 5 is threaded in the holder 1, and by clamping slot 7 further clamping and positioning, then pearl is placed in the deep-slotted chip breaker 3 of two holders of arranging relatively 1, open machine at last and carry out perforation processing by 2 pairs of pearls of centre bore by perforating needle.This apparatus structure is simple and practical, also applicable to the perforation processing of other circular article.
