Description
Technical Field
The utility model relates to the field of tooling design, in particular to a novel replaceable bushing.
Background
Certain titanium alloy parts are connected in a welding mode, and have certain deformation after welding, so that stable heat treatment and shape correction are required, and finally the appearance requirement of the parts is ensured. The stable heat treatment and shape correction of the parts by using the positioning holes is a common mode in the traditional mode, usually, the parts are provided with process holes at local positions, the parts are repaired and subjected to stable heat treatment, the parts are positioned by using the bottom holes of the process holes, and the bottom holes are drilled into final holes after the heat treatment. The assembly fixture (with the replaceable bushings of the bottom holes and the final holes, which is convenient for drilling holes on the frame) is utilized to manufacture the part hole site, so that the manufacturing cost can be saved, and the drilling precision of the part hole site can be improved. In the traditional mode, the replaceable bush is arranged on the clamp by utilizing friction force, but because the bush is easily fallen off from the clamp base body due to strong vibration when the drill bit contacts with the side wall of the bush when the replaceable bush is used for drilling, the problems of loss of the replaceable bush and deviation of drilling holes often exist.
Disclosure of Invention
The utility model aims at overcoming the defects in the prior art, and provides a novel replaceable bushing, so that the hole position of the replaceable bushing mounting fixture is ensured to be stressed without vibration and falling.
The purpose of the utility model is realized in the following way: the bushing is provided with a thick-diameter section, a middle-diameter section and a thin-diameter section, wherein the thick-diameter section and the middle-diameter section are provided with first cutting surfaces, the thick-diameter section is provided with a second cutting surface, the second cutting surface cuts off the whole thickness of the thick-diameter section, 2/3 thickness of the middle-diameter section is reserved, and the bushing is provided with an inner diameter hole;
the nut of the screw is matched with the end face of the second cutting surface.
Further, the first cutting surface and the second cutting surface have an included angle of 135 degrees.
Further, the nut of the screw is provided with a U-shaped groove.
The utility model has the beneficial effects that: the bushing is provided with a first cutting surface and a second cutting surface, the first cutting surface completely cuts off the thick-diameter section and the middle warp Duan Houdu, the second cutting surface completely cuts off the thickness of the thick-diameter section, and the thickness of a part of the middle warp section is reserved;
the first cutting surface and the second cutting surface are provided with an included angle, when the bushing is replaced, the screw is loosened, and the bushing is rotated to an angle until the nut of the screw is positioned at the first cutting surface, so that the bushing can be replaced smoothly.
Description of the drawings:
FIG. 1 is a schematic view of the replaceable bushing mounting structure of the present utility model;
FIG. 2 is a schematic view of the bushing structure of the present utility model;
fig. 3 is a schematic view of the structure of the screw of the present utility model.
Detailed Description
The present embodiment will be further described with reference to the accompanying drawings
As can be seen from fig. 1 to 3, the utility model comprises a bushing 2 and a screw 3, wherein the bushing 2 is provided with a thick diameter section 9, a middle diameter section 10 and a thin diameter section 11, the thick diameter section 9 and the middle diameter section 10 are provided with a first cutting surface 4, the thick diameter section 9 is provided with a second cutting surface 5, the second cutting surface 5 cuts off the whole thickness of the thick diameter section 9, the thickness of the middle diameter section 2/3 is reserved, and the bushing 2 is provided with an inner diameter hole 8.
The end face 6 of the nut of the screw 3 is matched with the end face of the second cutting surface 5, and the included angle between the first cutting surface 4 and the second cutting surface 5 is 135 degrees. The nut 12 is provided with a U-shaped groove 7, so that the disassembly and assembly are convenient.
When the bushing 2 is used, the small-diameter section 11 of the bushing 2 is firstly arranged in the process hole of the fixture 1, the small-diameter section 11 is completely pressed into the process hole until the end face of the middle-diameter end 10 is tightly attached to the surface of the fixture 1, and the large-diameter section is arranged to facilitate installation and removal of the bushing. The angle of the bushing is adjusted, the screw 3 is arranged in the auxiliary hole beside the bushing, the end face 6 of the screw is tightly pressed against the end face of the second cutting surface on the pitch diameter section after the screw is screwed, and the bushing 2 is prevented from vibrating and falling off in the use process. When the bush 2 is replaced, the screw 3 is loosened first, the bush 2 is rotated 135 degrees until the first cutting surface 4 is aligned with the direction of the screw, at this time, the screw cap 12 and the bush 2 do not interfere, and the screw can be taken out smoothly.
