Abstract
The utility model provides a swelling fixture for gear shaving. The fixture has the effects of reducing errors caused by clearances and improving the machining precision by adopting an internal swelling non-clearance fit clamping way for machining. To achieve the aims, the technical scheme adopted by the utility model is as follows: the swelling fixture for gear shaving comprises a mandrel (1), a plug (2), a plunger (3), a compression screw (4), a thin-wall sleeve (5), a liquid plastic (6) and a gland (8), wherein the thin-wall sleeve (5) and the mandrel (1) are in non-clearance fit; the liquid plastic (6) is filled between the mandrel (1) and the thin-wall sleeve (5); the port of the mandrel (1) is blocked by the plug (2); the compression screw (4) is compressed on the plunger (3); a workpiece (7) is sleeved on the mandrel (1); the end face of the workpiece (7) is in non-clearance contact with the positioning end face of the mandrel (1); the gland (8) is sleeved on the mandrel (1) at the other end of the workpiece (7); and the workpiece is clamped by core clampers at the two ends of a machine tool and the machine tool is started for gear shaving machining. The fixture has the following beneficial effects: errors caused by clearances are reduced and the machining precision is improved as the internal swelling non-clearance fit clamping way is adopted for machining.
Description
Technical field
The utility model relates to Gear Processing and uses anchor clamps, is specifically related to a kind of shaving anchor clamps that rise.
Background technology
The crankshaft toothed wheel of producing at present because the shape of gear is special, can only adopt gear shaping, shaving to process.Because the tooth runout during the preorder gear shaping is big, and is big through the gear-wheel gear-ring circular runout of gear shaping, revises through the postorder shaving.What conventional Fixture for Gear-shaving adopted is the gap axle, very little to the trim amount of gear ring circular runout.
Summary of the invention
The utility model provides a kind of shaving anchor clamps that rise, and does not have the clamping mode processing that the gap cooperates through adopting internal expanding, reduces the error that causes because of the gap, improves machining accuracy.
Be to realize above-mentioned purpose, take following technical scheme: the shaving anchor clamps that rise are made up of axle (1), plug (2), plunger (3), housing screw (4), thin walled cylinder body (5), liquid plastics (6) and gland (8) seven parts; Work is joined in thin walled cylinder body (5) and the no gap of axle (1), and liquid plastics (6) is filled between axle (1) and the thin walled cylinder body (5), stops up plug (2) at axle (1) port, and housing screw (4) is pressed on the plunger (3); Workpiece (7) is enclosed within on the axle (1), and workpiece (7) end face contacts in the crack with axle (1) location end face continuously; The axle (1) of workpiece (7) other end goes up cover gland (8).
The utility model usefulness is: owing to adopt internal expanding to have the clamping mode processing that the gap cooperates, reduce the error that causes because of the gap, improved machining accuracy.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Fig. 1 is the rise cutaway view of anchor clamps of shaving.
Illustration: axle 1, plug 2, plunger 3, housing screw 4, thin walled cylinder body 5, liquid plastics 6, workpiece 7, gland 8.
The specific embodiment
Because hole dimension is bigger in the workpiece 7, the clamping mode that can adopt internal expanding not have the gap cooperation is processed, and solves the machining accuracy problem.
As shown in Figure 1, the shaving anchor clamps that rise are made up of axle 1, plug 2, plunger 3, housing screw 4, thin walled cylinder body 5, liquid plastics 6, gland 8 seven parts; Thin walled cylinder body 5 is joined work with axle 1 no gap, and liquid plastics 6 is filled between axle 1 and the thin walled cylinder body 5, stops up plug 2 at axle 1 port; Housing screw 4 is pressed on the plunger 3; Overlap upper press cover 8 again on the axle 1 of workpiece 7 other ends.
In the operation, earlier the rise interior hole end surface of each position of anchor clamps and workpiece 7 of shaving is cleaned out, anchor clamps are stood up on workbench, be enclosed within workpiece 7 on the axle 1, workpiece 7 end faces are located end face with axle 1 and are contacted in the crack continuously; Tighten housing screw 4 promotion plungers 3 and move inward, compressing liquid plastics 6 makes thin walled cylinder body 5 produce micro-deformations, does not have the gap with workpiece 7 endoporus and contacts; On the axle 1 of workpiece 7 other ends, overlap upper press cover 8 again, rise anchor clamps and workpiece 7 of shaving clamped through the two ends of lathe are top.Start lathe and carry out shaving processing, the processing back dismounting shaving anchor clamps that rise take off gland 8 earlier, unclamp housing screw 4 again, and liquid plastics 6 promotes to block 3 and outwards moves, and thin walled cylinder body 5 resiles, and takes off workpiece 7; The shaving anchor clamps that rise are cleaned out, carried out the installation and the processing of next workpiece 7.
Claims (3)
1. shaving anchor clamps that rise is characterized in that: the said shaving anchor clamps that rise are made up of axle (1), plug (2), plunger (3), housing screw (4), thin walled cylinder body (5), liquid plastics (6) and gland (8) seven parts; Work is joined in thin walled cylinder body (5) and the no gap of axle (1), and liquid plastics (6) is filled between axle (1) and the thin walled cylinder body (5), stops up plug (2) at axle (1) port, and housing screw (4) is pressed on the plunger (3); Axle (1) other end cover gland (8).
