Abstract
The utility model relates to a special clamp, in particular to a clamp special for machining a locking hole of an expanding rod. The clamp aims to change the condition that when a bench worker draws lines and drills counter bored holes inside an expanding rod handle, the machining efficiency and the machining accuracy are low. The clamp comprises a clamp body and a drill bush. A square through hole is machined in one end surface of the clamp body, a round hole is machined in the upper surface of the clamp body and communicated with the square through hole, and the drill bush is installed in the round hole. A drilling head leading hole is machined in the upper end surface of the drill bush and communicated with the square through hole. The clamp is used for machining the locking hole of the expanding rod.
Description
Technical field
The utility model relates to a kind of special fixture, is specifically related to a kind of processing expander roll locking hole special fixture.
Background technology
Specific purpose tool when tube expander is nuclear power subsidiary factory assembling radiating tube, tube sheet, the important composition parts that expander roll is this instrument.Clamping and positioning hole when the counterbore being provided with in expander roll shank is use, when this counterbore of processing, adopts scribing by bench worker in the past, and by the processing mode of scribing by bench worker boring, working (machining) efficiency is low.
Utility model content
By scribing by bench worker, in expander roll shank, to bore counterbore working (machining) efficiency low in order to improve for the utility model, the situation that machining accuracy is low, and then a kind of processing expander roll locking hole special fixture is proposed.
The utility model is to address the above problem the technical scheme of taking to be: the utility model comprises clamp body and drill bushing, one end end face of clamp body is processed with square through-hole, the upper surface of clamp body is processed with circular hole, and circular hole is communicated with square through-hole, drill bushing is arranged in circular hole, drill bushing upper end end face is processed with drill bit and draws hole, and drill bit draws hole and is communicated with square through-hole.
The beneficial effects of the utility model are: the utility model is for batch machining expander roll locking hole, have greatly saved the non-cutting time of line, centering, have improved working (machining) efficiency 30%.During processing expander roll locking hole, owing to adopting special fixture to position, greatly improve the machining accuracy of locking hole, in reach ± 0.15mm of hole location, and improved the expander roll locking hole dimensional uniformity of same batch.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model, and Fig. 2 is the structural representation of clamp body.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1 to Fig. 2, described in present embodiment, a kind of processing expander roll locking hole special fixture comprises clamp body 1 and drill bushing 2, one end end face of clamp body 1 is processed with square through-hole 1-1, the upper surface of clamp body 1 is processed with circular hole 1-2, and circular hole 1-2 is communicated with square through-hole 1-1, drill bushing 2 is arranged in circular hole 1-2, and drill bushing 2 upper end end faces are processed with drill bit and draw hole 2-1, and drill bit draws hole 2-1 and is communicated with square through-hole 1-1.
The specific embodiment two: in conjunction with Fig. 1 to Fig. 2, present embodiment is described, a kind of processing expander roll locking hole special fixture also comprises holding screw 3 described in present embodiment, and holding screw 3 is arranged on the upper end of clamp body 1, and holding screw 3 is for locking drill bushing 2.Other composition and annexation are identical with the specific embodiment one.
Operation principle
When the utility model is used, by expander roll shank square tail with shaft shoulder axial location in the square through-hole of clamp body, drill bit draws hole by drill bit, completes the processing to expander roll locking hole.
