Abstract
The utility model discloses a blind hole D type is centre gripping frock for head, it includes the flange, be equipped with D type blind hole in the flange, be equipped with D type boss in the D type blind hole, the flange has the neck, and its neck is the centre gripping excircle. The utility model discloses simple structure can use after the shaping of producing once repeatedly, and the clamping of D type hook bolt location is accurate, and the cost of manufacture is lower, prevents that the clamping location of D type hook bolt is inaccurate, and the product head size thickness uniformity of at every turn processing is good, and unqualified phenomenon is showing and reduces. The very big has avoided head thickness size overproof, and the work load of doing over again and causing. Better spreading value has.
Description
Technical field
The utility model belongs to industrial processing technology field, particularly a kind of blind hole D type head clamping tooling.
Background technology
Along with increasing severely industrialization degree and day, having a extensive future of D type hook bolt, but bolt is in the process of processing head sizes, the Set and Positioning of D type hook bolt is inaccurate, the product head sizes variable thickness of each processing causes, and is even likely overproof, defective.The workload of clamping is larger.
Summary of the invention
The technical problems to be solved in the utility model is: provide that a kind of structure is simple, cost lower, easy for operation, efficient blind hole D type head clamping tooling, to overcome the technical deficiency of existing frock, makes not need artificial visually examine to locate, reduces workload.
The utility model is achieved in that a kind of blind hole D type head clamping tooling, and it comprises flange, is provided with D type blind hole in described flange, is provided with D type boss in described D type blind hole.
Described flange is with neck, and its neck is clamping cylindrical.
Described D type blind hole is consistent with the direction of D type boss.
The height of described D type boss is less than the degree of depth of described D type blind hole.
The height of described D type boss is the half of described D type blind hole depth.
Owing to have employed technique scheme, compared with the prior art, the utility model structure is simple, produce once shaping after can Reusability, the Set and Positioning of D type hook bolt is accurate, and cost of manufacture is lower, prevents the Set and Positioning of D type hook bolt inaccurate, the product head sizes consistency of thickness of each processing is good, and defective phenomenon significantly reduces.Avoid head thickness dimension overproof greatly, and the workload caused of doing over again.There is good promotional value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model;
In figure: 1-flange, 2-D type blind hole, 3-clamps cylindrical, 4-D type boss.
Detailed description of the invention
The utility model is set forth further below in conjunction with specific embodiment or accompanying drawing, but not as the restriction foundation to protection domain; Any improvement project in the utility model right, all should be considered as protection domain of the present utility model.
A kind of blind hole D type head clamping tooling, it comprises flange 1, is provided with D type blind hole 2 in described flange 1, is provided with D type boss 4 in described D type blind hole 2.
Described flange 1 is with neck, and its neck is clamping cylindrical 3.
Described D type blind hole 2 is consistent with the direction of D type boss 4.
The height of described D type boss 4 is less than the degree of depth of described D type blind hole 2.
The height of described D type boss 4 is the half of described D type blind hole 2 degree of depth.
Process this blind hole D type head clamping tooling, first utilize the external dimensions of the flange 1 of lathe turning tooling, clamping cylindrical 3, recycling stamping machine one-shot forming punching press D type blind hole 2 and D type boss 4, finally perform and polish.Its structure is simple, can Reusability, and the Set and Positioning of D type hook bolt is very accurate, and simple to operate, efficiency is high.Can not be inaccurate because of the Set and Positioning of bolt, cause the product head sizes uniformity of processing bad, qualification rate significantly reduces, and the overproof of generation is done over again, and has good promotional value.
