Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 1-4, a kind of drive balls chain installs fixture, the 2-1 of clamp body one, the 2-2 of clamp body two, driving wire are included
Thick stick 4 and guide rod 5, the centre of turn-screw 4 is square structure, and the both sides of the square structure of turn-screw 4 are respectively equipped with positive left-hand thread T
Type screw thread, the both ends of the 2-1 of clamp body one and the 2-2 of clamp body two respectively with turn-screw 4 are threadedly coupled, the 2-1 of clamp body one and folder
Specific two 2-2 is fixedly connected by guide rod 5.
In the present embodiment, the material of turn-screw 4 is 40Cr, is heat-treated 32 ~ 36HRC.The centre of turn-screw 4 it is square
Structure is six sides 10 of rotation, and the both sides of six sides 10 of rotation are respectively positive and negative T-shaped screw thread, and turn-screw 4 is adjusted by using spanner
The middle side 10 of rotation six, it is possible to achieve the 2-1 of the clamp body one and 2-2 of clamp body two is collapsed with separating along the axial direction of turn-screw 4.
Guide rod 5 is arranged in parallel with turn-screw 4, and guide rod 5 mainly plays the 2-1 of clamp body one and the 2-2 of clamp body two guide effect, is
Ensure that chain effectively aligns, guiding clearance is controlled within 0.3mm.
Referring to the drawings 3,4, the 2-2 of clamp body two is axle sleeve structure, and material 40Cr, the 2-2 of clamp body two grab provided with work
14, it is half arcuate structure that work, which grabs 14, can go deep between chain roller catching on chain roller, the work that chain clamps grabs 14 using heat
Handle 32 ~ 36HRC.It is 8mm standard keyways 2 13 that width is axially opened up in clamp body 2-2 axle sleeve, and the material of feed screw nut 1 is
ZQSn6-6-3, the outer surface axial direction milling length of feed screw nut 1 are 40mm standard keyway 1, are coordinated with flat key 7, leading screw
