Abstract
A mutual locking type positioning bolt component comprises two or more D-head bolts and a locking and positioning pad, wherein each D-head bolt is provided with a bolt head notch, bolt holes are formed in the locking and positioning pad, the number of the bolt holes is the same as that of the D-head bolts, a locking and positioning reed is arranged beside each bolt hole of the locking and positioning pad, the D-head bolts are installed after penetrating through the locking and positioning pad, and the locking and positioning reeds interfere with the bolt head notches after being folded to prevent the D-head bolts from rotating. According to the mutual locking type positioning bolt component, the locking and positioning reeds can transmit torque and prevent bolt heads from rotating accordingly after being folded, other assembly interference is avoided, wrenching space is not needed, the relative torsional angle positional relations between connecting parts are restrained, and locking effect is good; a lining enables the positions of a base body and a part to be fastened to be adjustable during installation, so that an ideal installing and fastening effect is realized; installation requirements are met, performance is reliable, structure is simple, cost is low, and usage and maintenance are convenient.
Description
Technical field
The present invention relates to a kind of bolt, be specially a kind of phase mutually stop jack bolt assembly.
Background technique
At present in high-tech area Course Exercise in Machinery Elements Design, integrate multifunctionality, the high-end fastener technology requirement that reliability is strong is high, complex structure, technology difficulty are large, expensive.The accurate restriction accurately limiting the torsion angle of relative position particularly between two parts between two parts is often required in Modern mechanical design, avoid cold welding between part bonding, the impact by assembly unit space require product design size littlely to dodge that space is large, twisting convolution space as far as possible little, stopping effect good.Can effectively protect matrix part, registration, installing/dismounting high-end firm fast and easily.Reach above-mentioned requirements conventional design to need to adopt complicated mechanical structure and multiple-unit design.And be the jack bolt assembly solving an above-mentioned difficult problem; limit the relative position between two parts, avoid cold welding, dodge space large, be integrated well without the need to twisting convolution space, stopping effect, can effectively protect matrix part, registration, installing/dismounting efficient and convenient, prior art but can not meet that reliable performance, structure are simple, with low cost, working service basic demand easily simultaneously.
Summary of the invention
The object of this invention is to provide and a kind ofly meet background technique and require to have concurrently that reliable performance, structure are simple, with low cost, a kind of phase mutually stop jack bolt assembly of working service basic demand easily simultaneously.
In order to achieve the above object, the technological scheme adopted is: a kind of phase mutually stop jack bolt assembly, comprise plural D type hook bolt and stop locating pad, described D type hook bolt is provided with bolt head breach, described stop locating pad is provided with the bolt hole identical with D type hook bolt quantity, and the bolt hole of stop locating pad is other is provided with stop location tongue; Described D type hook bolt is installed through after stop locating pad, and stop location tongue is interfered with described bolt head breach after turning up, and prevents D type hook bolt from rotating.
The bolt shank of D type hook bolt is provided with lining, and lining avoids D type hook bolt and fixing body directly to interfere.
D type hook bolt material is structural steel 40Cr, 30CrMnSi, 40CrNiMo or 38CrA.
Stop locating pad material is structural carbon steel 20#, 25# or 08F.
Lining material is lead brass HPb59-1.
This phase mutually stop jack bolt assembly can be used for plural separation or/and can the fastening installation of mutual mobile matrix, whole D type hook bolts is passed stop locating pad by bolt hole, put lining again passed installation matrix and needed fastening workpiece, nut of screwing on after packing ring is installed, matrix to be installed and fastener without move axially but still rotatable time stop being screwed into nut, now adjustment installs the mutual alignment of matrix and fastener to suitable, turn up the rotation that stop location tongue interferes D type hook bolt head afterwards, last fastening nut.
The beneficial effect of employing technique scheme is: after on this phase mutually stop jack bolt assembly, the stop location tongue of stop locating pad is turned up, transmitting torque restriction bolt head can be reached and follow rotation, avoid other Assembly Interference, comparatively traditional polygon design is without the need to twisting convolution space; Bolt shank is provided with the direct interference that lining can avoid bolt and fixing body, preferably in rotation or the floating position of installing fastener cycle adjustment installation matrix and fastener, can reach desirable and install fastening effect; Stop location tongue limits the relative torsional angle position relationship between each link accurately, and stopping effect is good; Lining employing lead brass HPb59-1 avoids the diffusion bonding between material, eliminates cold welding phenomenon, protects matrix part; Possess reliable performance while making it meet installation needs, structure is simple, with low cost, working service is effect easily.

Embodiment
Below in conjunction with drawings and Examples, the present invention is explained.
A kind of phase mutually stop jack bolt assembly, comprise two D type hook bolts 1 and stop locating pad 2, described D type hook bolt 1 is provided with bolt head breach 11, and described stop locating pad 2 is provided with two bolts hole 22, is equipped with stop location tongue 21 outside the bolt hole 22 of stop locating pad 2; The bolt shank of D type hook bolt 1 is provided with lining 3, and lining 3 avoids D type hook bolt 1 and fixing body directly to interfere.Described D type hook bolt puts lining 3 again through after stop locating pad 2, penetrate again and matrix and fastener installation are installed, nut 5 of screwing on after packing ring 4 is installed, matrix to be installed and fastener without move axially but still rotatable time stop being screwed into nut 5, now adjustment installs the mutual alignment of matrix and fastener to suitable, turn up stop location tongue 21 again and interfere the rotation of D type hook bolt 1 head, bolt head to circle round space without the need to twisting, last fastening nut 5.Stop location tongue 21 is interfered with described bolt head breach 11 after turning up, and prevents D type hook bolt 1 from rotating.This phase mutually stop jack bolt assembly can be used for plural separation or/and can the fastening installation of mutual mobile matrix.
It is shaping that D type hook bolt 1 material is that the good materials of thermoplasticity such as structural steel 40Cr, 30CrMnSi, 40CrNiMo or 38CrA are convenient to the blank upsetting of part.Raw material hardenability is better convenient to obtain higher surface hardness, improves the wear resistance of product.
