The compression bar of threaded connection, the threaded hole lower end are equipped with the T-slot along holder bevel direction, and being equipped with sliding in the T-slot connects
The sliding block connect, the clamping face that it is 120 ° with holder inclined-plane angle that the sliding block, which is equipped with, the holder both ends are respectively equipped with straight line
Driving device one and linear drive apparatus two, one front end of the linear drive apparatus are equipped with the compression moved along floor length direction
Block one, two front end of the linear drive apparatus are equipped with the compact heap two moved along floor length direction.
Preferably, the compact heap one is consistent with bolt head cross-sectional sizes to be processed, the compact heap two with it is to be processed
Bolt shank cross-sectional sizes are consistent.
Preferably, the linear drive apparatus one and linear drive apparatus two are any one of linear stepping motor or cylinder
Kind.
Preferably, the straight-line trajectory of the compact heap one and compact heap two is on the axis of symmetry of holder.
It is using the advantageous effect of above technical scheme：The present invention a kind of bolt boring grab, this fixture it is specific
Application method is：Bolt to be processed is laterally disposed, so that the two sides of bolt head is located on the inclined-plane of holder, by sliding block
Bolt head is slid into, the clamping face on sliding block is made to be contacted with other two side of bolt head, bolt head is positive six side
Shape, each angle are 120 °, and the inclined-plane angle of clamping face and holder is 120 °, clamp face and holder inclined-plane jointly by bolt head
Two diagonal clampings, rotation compression bar make compression bar front end hold out against sliding block on the side of bolt head, then by compact heap one and pressure
Tight block two stretches out, and compact heap one withstands the head of bolt, and compact heap two withstands the bar portion of bolt, and bolt to be processed is by completely solid
It is fixed, it is then drilled to bolt head by drilling equipment, the hexagon bolt head that all sizes are utilized in this fixture is positive six
The characteristics of side shape, from two diagonal angles of bolt head is clamped fixation, phase using angle for 120 ° of holder and clamping face
Than conventional brace, this fixture it is versatile, be suitble to all hexagon bolt head bore operations, eliminate for different size spiral shell
Bolt makes the trouble of fixture, reduces fixture cost.

Specific implementation mode
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Fig. 1-4 shows the specific implementation mode of the present invention：A kind of boring grab of bolt, including bottom plate 1, the bottom plate 1
Middle part is equipped with symmetrical holder 6, and the section of the holder 6 is right-angled trapezium and inclined-plane and the angle with bottom plate 1 is 60 °, described
The upper end of holder 6 is equipped with threaded hole 10, and the central axes of the threaded hole 10 are parallel with the inclined-plane of holder 6, in the threaded hole 10
