Abstract
The utility model discloses a transitional connecting rod device for boring a deep hole. The transitional connecting rod device comprises a transitional connecting rod and a compression screw, wherein the transitional connecting rod comprises two parts, namely a cutter fixed mounting end and a transitional connecting rod fixed mounting end; an axial positioning step surface is formed between the cutter fixed mounting end and the transitional connecting rod fixed mounting end; a mounting hole matched with a cutter shank part is formed at the cutter fixed mounting end in the length direction; a screw mounting counter bore matched with the compression screw is formed on the wall of the mounting hole; the transitional connecting rod fixed mounting end is in a cylinder; the outside diameter of the transitional connecting rod fixed mounting end is matched with the size of an inner hole boring cutter holder on a cutter head; and a cooling water channel is arranged inside the transitional connecting rod and is communicated with the mounting hole. According to the transitional connecting rod device for boring the deep hole, which is provided by the utility model, the deep hole can be processed by adopting a general boring cutter made of internal chilling steel instead of a shockproof boring cutter or a shockproof hard alloy cutter, so that the production cost is reduced; and the transitional connecting rod device is suitable for processing various medium-small batches of deep hole parts.
Description
Technical field
The utility model relates to Digit Control Machine Tool, relate in particular to a kind of be used endoporus boring cutter seat on the cutterhead with clamping common in the cold steel borer transition extension bar device that carries out deep hole boring processing.
Background technology
In machining; The deep hole part processing is the difficult point of machining always, and conventional processing method is to adopt external advanced shockproof borer or shockproof hard alloy cutter to carry out deep hole machining, and the working depth draw ratio can reach 5～10 times; Can satisfy the machining requirement; But shockproof borer and shockproof hard alloy cutter price are ten times of common steel boring bar, even tens times, not high for its processing economic feasibility of parts in small batch.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provide a kind of can clamping common in cold steel borer realize the transition extension bar device of deep hole boring processing reducing the cutter purchase cost.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of deep hole boring is with transition extension bar device; Comprise transition extension bar and housing screw; Said transition extension bar comprises cutter fixed installation end and transition extension bar fixed installation end two parts, between cutter fixed installation end and transition extension bar fixed installation end, forms the axial location step surface; Said cutter fixed installation end is provided with the installing hole that matches with tool shank along its length, on the hole wall of installing hole, is provided with the suitable screw of housing screw counterbore is installed; Said transition extension bar fixed installation end is cylinder, and the endoporus boring cutter seat size on its external diameter and the cutterhead is suitable; Inside at the transition extension bar also is provided with cooling-water duct, and said cooling-water duct is connected with installing hole.
During installation; At first transition extension bar fixed installation end is fixed in the endoporus boring cutter seat on the cutterhead; Again tool shank is placed in the installing hole, use housing screw to pass screw installation counterbore cutter is fixed on the transition extension bar, note adjusting cutter nose center high position during fixed cutting tool.During use, start the lathe coolant pump, the endoporus boring cutter seat that cooling fluid is passed through on the cutterhead imports in the cooling-water duct, and the point of a knife from cutter goes out ejection again, realizes the cutter cooling of process.
This transition extension bar device mainly is applicable to the steel borer.
Beneficial effect: a kind of deep hole boring that the utility model provides is with transition extension bar device, make the processing of deep hole can adopt common in cold steel borer substitute shockproof borer or shockproof hard alloy cutter, reduced production cost; And the design of cooling-water duct can realize that inner water outlet cools off cutter; Be applicable to the processing of many kinds, small batch deep hole part.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Be illustrated in figure 1 as a kind of deep hole boring with transition extension bar device; Comprise transition extension bar 3 and housing screw 5; Said transition extension bar 3 comprises cutter fixed installation end and transition extension bar fixed installation end 6 two parts, between cutter fixed installation end and transition extension bar fixed installation end 6, forms the axial location step surface; Said cutter fixed installation end is provided with the installing hole 2 that matches with cutter 1 shank along its length, on the hole wall of installing hole 2, is provided with housing screw 5 suitable screws counterbore is installed; Said transition extension bar fixed installation end is cylinder, and the endoporus boring cutter seat size on its external diameter and the cutterhead is suitable; Inside at transition extension bar 3 also is provided with cooling-water duct 4, and said cooling-water duct is connected with installing hole 2; Cutter 1 be in cold steel borer.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
