Abstract

The utility model discloses a crank shaft chuck fixing device which comprises a horizontal lathe. The two ends of the horizontal lathe are provided with a spindle box and a tailstock respectively. A four-jaw chuck is installed on the spindle box, a taper hole is formed in the tailstock, a tailstock connecting shaft is installed in the taper hole, a bearing and a chuck connecting shaft are fixed in the tailstock connecting shaft, one end of the chuck connecting shaft is fixed in the bearing, and the other end of the chuck connecting shaft is fixedly provided with a four-jaw chuck. According to the crank shaft chuck fixing device, a crank shaft to be machined is fixed to the horizontal lather through the four-jaw chuck on the chuck connecting shaft and the four-jaw chuck on the spindle box, the positions of the two four-jaw chucks at the two ends are adjusted to enable the rotary center of the crank shaft to be changed, and then a center hole or a correction hole is formed. After the rotary center of the crank shaft is changed, machining allowance is uniform, and the hardness difference is reduced.

Description

A kind of bending axis chuck fixing means
Technical field
The utility model relates to the fixture of axle class processing, is specifically related to a kind of bending axis chuck fixing means.
Background technology
Chuck can be used for clamping workpiece, solid and reliable, and four claws of chuck can be adjusted, and make its centre of gyration that can change irregular or regular part, by coordinating dial gauge or amesdial can adjust to very accurately needed part revolution axle center.General general chuck is contained on main shaft, with main shaft, rotates.
Most of axial workpieces need to carry out modified heat treatment, for the larger axle of diameter, if by quenching in shaft furnace heating, quenching liquid pool, then high tempering, be out of shape very little.If heated in batch-type furnace, tempering furnace is also batch-type furnace, and the distortion of axle is very large, and bending likely surpasses 20mm, and alignment is also inconvenient.Therefore, guarantee that axle can all process, before heat treatment, roughing allowance is very large.Due to quenching and tempering hardness gradient problem, even if axle is out processed, it is very large that the hardness of same axis differs, and cannot meet product design requirement.The chuck fixing means of existing bending axis class can not be repaiied crooked axle two ends centre bore in the situation that roughing allowance is less, can not guarantee that processing capacity is even.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
Utility model content
The purpose of this utility model is to provide a kind of revolution axial line that can change axle, makes its allowance less, the uniform bending axis chuck fixing means of hardness.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of bending axis chuck fixing means is provided, comprise horizontal lathe, the two ends of horizontal lathe are respectively main spindle box and tailstock, and chuck is installed on main spindle box, and tailstock is provided with taper hole, tailstock connecting axle is installed in taper hole, the inside of tailstock connecting axle is fixed with bearing and chuck connecting axle, and one end of chuck connecting axle is fixed in bearing, and the other end is fixed with chuck.
Preferably, between tailstock and lathe, be provided with slide of tail stock bottom.
Preferably, on tailstock connecting axle, bearing gland is installed.
Preferably, the junction of chuck connecting axle and chuck is provided with pressing plate.
In sum, the utlity model has following advantage:
Chuck by the chuck on chuck connecting axle and main spindle box is fixed on the bending axis of needs processing on horizontal lathe, and adjusts the position of two ends chuck, the centre of gyration of bending axis is changed, reprocessing centre bore or trimming hole; The centre of gyration of bending axis makes allowance even after changing, and difference of hardness reduces.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the cutaway view of Figure 1A part.
Wherein, 1, horizontal lathe; 2, main spindle box; 3, tailstock; 4, chuck; 5, taper hole; 6, tailstock connecting axle; 7, bearing; 8, chuck connecting axle; 9, slide of tail stock bottom; 10, bearing gland; 11, pressing plate; 12, bending axis.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
As depicted in figs. 1 and 2, the utility model provides a kind of bending axis chuck fixing means, and the main body of this device is horizontal lathe 1, and horizontal lathe 1 plays the stable effect of load-bearing.The two ends of horizontal lathe 1 are respectively main spindle box 2 and tailstock 3, and chuck 4 is installed on main spindle box 2, and this chuck 4 can not rotate with bending axis 12.Tailstock 3 is provided with taper hole 5, and taper hole 5 is for installing fixedly tailstock connecting axle 6.The inside of tailstock connecting axle 6 is fixed with bearing 7 and chuck connecting axle 8, and one end of chuck connecting axle 8 is fixed in bearing 7, and the other end is fixed with chuck 4.Chuck connecting axle 8 can rotate at the internal freedom of tailstock connecting axle 6, chuck 4 is fixed on chuck connecting axle 8, rotation with chuck connecting axle 8 is rotated, and coordinates with the chuck 4 being fixed on main spindle box 2, and the bending axis 12 of needs processing is fixed on horizontal lathe 1.
Bending axis 12 clampings are on the chuck 4 of main spindle box 2 and tailstock 3, and now bending axis 12 has an actual axial line, axis of rotation is and offset.Now adjust the position of two ends chuck claw 4, the axial line of bending axis 12 and axis of rotation are changed.The regulating degree of claw adjusts accordingly according to the degree of crook of bending axis 12.
Further, between tailstock 3 and horizontal lathe 1, be provided with slide of tail stock bottom 9.
Chuck connecting axle 8 and bearing 7 are arranged on tailstock connecting axle 6 inside, in order to make its fixed effect better, bearing gland 10 are installed on tailstock connecting axle 6.Bearing gland 10 center is provided with a perforate, and chuck connecting axle 8 is passed.Bearing gland 10 makes the fixed effect of bearing 7 and chuck connecting axle 8 better, is not easy to come off.
Further, chuck connecting axle 8 is provided with pressing plate 11 with the junction of chuck 4.
Although by reference to the accompanying drawings the specific embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
