Abstract
The invention relates to a clamp pull rod, in particular to the field of mechanical manufacture clamps. The invention provides the clamp pull rod with adjustable length, which comprises a rod body and a threaded joint. The rod body comprises a rod sleeve and a sub rod which can be embedded into an inner cavity of the rod sleeve, the threaded joint is respectively fixed on the top of the rod sleeve and the top of the sub rod, a plurality of equidistant radial locating pin holes are drilled on the rod sleeve and the sub rod, and the rod sleeve and the sub rod are fixedly connected by pins penetrating through the locating pin holes. The purpose of changing the length of the pull rod is achieved by regulating the length of the sub rod extending out from the rod sleeve, thereby materials for manufacturing the pull rods with different lengths are saved, and the cost is lowered.
Description
Technical field
The present invention relates to a kind of clamp pull rod, particularly machine-building anchor clamps field.
Background technology
In the machine-building process, usually use frock clamp, and pull bar is the most common, it is usually used in being connected and fixed of nipper, when because it is a regular length, causes different anchor clamps need make the pull bar of different length, both waste material had also improved cost simultaneously.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of clamp pull rod of adjustable length.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of clamp pull rod, comprise shaft, nipple, its innovative point is: described shaft comprises the bar cover and can be embedded in the sub bar of bar cover inner chamber, described nipple is separately fixed at the top of bar cover, sub bar, be drilled with some equidistant radial location pin-and-holes on described bar cover and sub bar, described bar cover is connected and fixed by passing the dowel hole pin with sub bar.
The invention has the advantages that: reach the purpose that changes pull bar length by the length of regulating sub bar extension bar cover, saved the material of making the different length pull bar, reduced cost.
Description of drawings
Figure is the structural representation of clamp pull rod of the present invention.
The specific embodiment
As shown in the figure, comprise shaft 1 and nipple 2, described shaft 1 comprises bar cover 3, sub bar 4, described sub bar 4 can be embedded in the inner chamber of bar cover 3, described nipple 2 is separately fixed at the top of bar cover 3, sub bar 4, be drilled with some equidistant radial location pin-and-holes 5 on described bar cover 3 and the sub bar 4, described bar cover 3 is connected and fixed by pin 6 with sub bar 4.When needing to change pull bar length, extract pin 6, the length of regulating sub bar 4 extension bars cover 3 is inserted dowel hole 5 with pin 6 again to correct position.
Claims (1)
