Abstract
The utility model provides an electroplating diamond hole drill easy to be machined and produced, comprising a hole drill basal body, and a drill shank. The utility model is characterized in that the hole drill basal body and the drill shank have split structures, and the split structures are connected together by a clamping device.
Description
Skill this area
The utility model relates to plating diamond tool, particularly a kind of electroplated diamond hole drill.
Background technology
The electroplated diamond hole drill is that a kind of thin-walled hollow bores, and shows good performance during use.In the prior art, the matrix material of hole drill generally uses steel, and is to form with round steel turning.The staving structure part of hole drill matrix is divided into integral type or monolithic construction with the drill shank on its bottom, and it is a lot of not only to expend steel, and amount of machining is very big, and cost is very high, and processing inconvenience.Because hole drill matrix of the prior art and drillstock are monolithic construction,, cause waste in case after the drilling portion that electroplated diamond constituted damages, just get only integral body and abandon.In order to reduce cost, the inventor has conceived split or split-type structural, promptly produces hole drill matrix and drillstock respectively, then with the combination of hole drill matrix and drillstock or assemble the electroplated diamond hole drill, for this reason, inventor's development experiments success punching press matrix.Adopt the punching press matrix as the hole drill matrix, compare with turning matrix of the prior art, expend steel and significantly reduce, production efficiency also greatly improves, and for instance, with the steel plate punch forming of 1.0-1.2mm, carries out electroplated diamond again.The matrix cost is fallen much like this, is example with diameter 100mm hole drill matrix, and car becomes the hole drill matrix to need 40 yuans one, and punching press matrix cost is 5 yuans one, greatly reduces manufacturing cost.
The utility model content
The utility model provides a kind of electroplated diamond hole drill of being convenient to processing and fabricating at defective that exists in the prior art or deficiency.
Inventive concept of the present utility model is by the monolithic construction of hole drill matrix and drillstock being changed into split or split combination structure, so that processing and fabricating.
The technical solution of the utility model is as follows:
The electroplated diamond hole drill comprises hole drill matrix and drillstock, it is characterized in that: described hole drill matrix and described drillstock are the split structure, and this split structure links together by fastener.
Described fastener is the structure that is threaded.
The described structure that is threaded is arranged on the described drillstock.
Described fastener comprises the part that snaps in of the suitable described drillstock of the connecting hole of hole drill matrix bottom and this connecting hole, and this snaps in the axial compression nut of part top.
Technique effect of the present utility model is as follows:
Because electroplated diamond hole drill of the present utility model, hole drill matrix and drillstock are designed to the split structure, and this split structure links together by fastener, that is to say, can produce hole drill matrix and drillstock respectively, then with the combination of hole drill matrix and drillstock or assemble the electroplated diamond hole drill, like this, just brought convenience, and helped standardization or generalization production to processing and fabricating.
Because fastener is the structure that is threaded; This structure that is threaded is arranged on the drillstock, so just makes drillstock be equivalent to a special-shaped double-screw bolt, can reach the coordinating and unifying of function and structure, makes, uses and assemble all more convenient.
Since fastener comprise hole drill matrix bottom connecting hole and with the part that snaps in of the suitable drillstock of this connecting hole, and this snaps in the axial compression nut of part top, this just makes that combined type electroplated diamond hole drill mounting or dismounting of the present utility model are convenient, and Stability Analysis of Structures during use is safe and reliable.

Fig. 3 is an electroplated diamond hole drill combining structure schematic diagram.
Reference numeral lists as follows:
1-drillstock installing hole; 2-round bottom part; The 3-chip-removal hole; 4-electroplated diamond layer; The 5-clamp nut; 6-drillstock head; The 7-threaded portion; 8-drillstock bar portion; 9-ring wall part; The 10-segmental arc; 11-snaps in part.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the basal body structure of electroplated diamond hole drill is formed by round bottom part 2 with along the ring wall part 9 of its peripheral projection, has punching press between round bottom part 2 and the ring wall part 9 to draw the segmental arc 10 that forms; This basal body structure does not comprise the drillstock part, compare with turning matrix of the prior art, bigger variation has taken place, this just makes this basal body structure be suitable for adopting the punching press drawing and moulding, helping saving steel, to reduce amount of machining, thereby can reduce cost greatly.The surrounded surface of ring wall part 9 is provided with chip-removal hole 3, and chip-removal hole 3 has four, and is radially uniform.The center of round bottom part 2 is provided with drillstock installing hole 1.Drillstock installing hole 1 is the rectangle design of circular arc for two ends.The steel plate thickness that punching press is drawn is the 1-2 millimeter.The specification of hole drill is any one specification between the 1-4 inch.Fig. 1 also shows the electroplated diamond layer 4 that is positioned at hole drill matrix mouth edge.Adopt the punching press matrix as the hole drill matrix, compare, expend steel and significantly reduce with turning matrix of the prior art, production efficiency also greatly improves, for instance, with the steel plate punch forming of 1.0-1.2mm, carry out electroplated diamond again, the matrix cost is fallen much like this, with diameter 100mm hole drill matrix is example, and car becomes the hole drill matrix to need 40 yuans one, and punching press matrix cost is 5 yuans one, this shows, greatly reduce manufacturing cost.
Fig. 3 shows the combining structure of electroplated diamond hole drill of the present utility model, the basal body structure and the drillstock part that comprise the electroplated diamond hole drill, this basal body structure is formed by round bottom part 2 with along the ring wall part 9 of its peripheral projection, be segmental arc 10 between round bottom part 2 and the ring wall part 9, a mouthful edge is an electroplated diamond layer 4; The drill shank branch comprises fastener, and this fastener and drillstock bar portion 8 are designed to one, and clamp nut 5 and drillstock head 6 make by screw thread 7 and snap in part 11 and block in the drillstock installing hole of basal body structure.Also show equally distributed chip-removal hole 3 on the ring wall part 9 among the figure.
Should be pointed out that the above specific embodiment can make those skilled in the art more fully understand the utility model, but limit the utility model never in any form.Therefore, although this specification has been described in detail the utility model with reference to drawings and Examples,, it will be appreciated by those skilled in the art that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit of the present utility model and technical spirit, and it all should be encompassed in the middle of the protection domain of the utility model patent.
