Abstract
The utility model relates to a frock clamp technical field specifically is a hand claw formula of steel sheet drill bit is top. This hand claw formula is top should be able to to be used for centre gripping steel sheet drill bit, avoids appearing skidding, has simple structure, convenient operation's technical characterstic moreover. The utility model provides a hand claw formula of steel sheet drill bit is top which characterized in that: including top main part, a plurality of hand claw has evenly been arranged to the tip of top main part, and each hand claw outwards opens to the top from the root of being connected with top main part gradually, the centre gripping mouth of formation centre gripping steel sheet drill bit. As preferred, every hand claw system has two inclined planes, and two inclined planes intersect the bite of the edge of department as centre gripping steel sheet drill bit.
Description
Technical field
The utility model relates to technical field of tooling clamps, and specifically a kind of gripper type of steel plate drill bit is top.
Background technology
Steel plate drill bit is one of common drill bit, be usually divided into spiral bit and core drill first two, be mainly used in punching to sheet metals such as steel plate, section bar, aluminium alloy plates, be generally arranged on drilling machine and support the use.In the production process of steel plate drill bit, need the helicla flute of processing drill, need in whole process to clamp drill bit.Generally at present use Double Tops point to be clamped by drill bit, defect be drill bit and top between easily skid, affect the quality of product.
Utility model content
The technical problems to be solved in the utility model is the deficiency overcoming above-mentioned background technology, provides a kind of gripper type top, and this gripper type top should be able to being used for clamps steel plate drill bit, avoids occurring skidding, and has simple, the easy to operate technical characterstic of structure.
The technical solution adopted in the utility model is:
A kind of gripper type of steel plate drill bit is top, it is characterized in that: described gripper type is top comprises top main body, the end of top main body has been evenly arranged several paws, and each paw outwards opens from the root be connected with top main body gradually to top, forms the clamp port of clamping steel plate drill bit.
As preferably, each paw is shaped with two inclined-planes, and the seamed edge of intersection, two inclined-planes is as the bite of clamping steel plate drill bit.
As preferably, the afterbody of described top main body is shaped with clamping section.
The beneficial effects of the utility model are: the utility model uses the original bevel-type of the top replacement of gripper type top, utilize the seamed edge of multiple paw to clamp one end of steel plate drill bit, clamping effect is good, can effectively avoid skidding, make Product processing size accurate, be applicable to enterprise and use.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is left TV structure enlarged diagram of the present utility model.
Fig. 3 is working state schematic representation of the present utility model.
Detailed description of the invention
The utility model is described in further detail below, but the utility model is not limited to following examples.
As shown in Figure 1 and Figure 2, gripper type described in the utility model is top comprises top main body 4, the end of top main body has been evenly arranged several paws 5, and (minimum is 3, in figure be 4), each paw outwards opens from the root be connected with top main body gradually to top, forms the clamp port of clamping steel plate drill bit 7.Each paw is shaped with the bite of seamed edge 6 as clamping steel plate drill bit of 3, two intersections, inclined-plane, two inclined-planes.The afterbody of described top main body is shaped with clamping section (clamping for scroll chuck 9).
As shown in Figure 3, during utility model works and bevel-type top 10 support the use, bevel-type top 10 is in opposite directions top and to layout with gripper type, both are positioned on the workbench 8 of lathe respectively by scroll chuck 9 and mount pad 2, gripper type is top to be driven by drive unit 1, and this drive unit is generally the motor with reductor.The afterbody of described top main body is shaped with clamping section.During clamping, the axis of steel plate drill bit and the axis coaxle that gripper type is top and bevel-type is top, the clamping that the top utilizing bevel-type top is pressed and gripper type is top, fixed by steel plate drill bit, gripper type is top prevents steel plate drill slipping by multiple gripping point.
Finally, it should be noted that above what enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have a lot of distortion.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed in the utility model, all should think protection domain of the present utility model.
