Summary of the invention
The object of the invention is, in order to overcome above deficiency, provides a kind of complex structure, manufactures processing simple, precision high for processing the fixture of emergency pump camshaft and using the method for its machining cam axle.
Object of the present invention is achieved through the following technical solutions: a kind of for processing the fixture of emergency pump camshaft, comprise base plate, one end of base plate is connected with the first riser by the first screw, the other end of base plate is provided with the second riser, one side of the first riser is provided with eccentric center borehole jack, eccentric center borehole jack is connected with nut, the inside of eccentric center borehole jack and nut is connected with a collet chuck jointly, the second riser is connected with borehole jack by the second screw, the outside of borehole jack is connected with pressure head, pressure head is connected with thin cylinder, and eccentric center borehole jack and borehole jack are staggered relatively.
Further improvement of the present invention is: the outside of described eccentric center borehole jack and borehole jack is equipped with two group switching centre holes.
Further improvement of the present invention is: described in every group, the angle of centre bore is 60 °.
Adopt for processing the method for the fixture machining cam axle of emergency pump camshaft, comprise the following steps:
The not eccentric excircle at A, first machining cam shaft-like work two ends, then installs to camshaft workpiece on fixture;
B, fixture is installed to together with camshaft workpiece to the top upper of numerically controlled lathe, two eccentric cam cylindricals on machining cam shaft-like work respectively then, every group of corresponding eccentric cam cylindrical of centre bore processing;
C, the camshaft workpiece after processing is taken off from fixture, then heat-treat;
After D, heat treatment, treated camshaft workpiece is gone up to fixture again, adopt and on cylindrical grinder, grind two eccentric cam cylindricals with identical before method.
The present invention compared with prior art has the following advantages: on the common apparatus such as numerically controlled lathe and common cylindrical grinder, manufacture camshaft, solved the dependence to special equipment, effectively reduced development cost, shortened the construction cycle, the camshaft precision after having manufactured is higher.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-base plate, 2-the first screw, 3-the first riser, 4-the second riser, the eccentric centre bore of 5-, 6-nut, 7-collet chuck, 8-the second screw, 9-borehole jack, 10-pressure head, 11-thin cylinder, 12-be eccentric excircle, 13-eccentric cam cylindrical, 14-centre bore not.
the specific embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1, to show the present invention a kind of for processing the specific embodiment of the fixture of emergency pump camshaft, comprise base plate 1, one end of base plate 1 is connected with the first riser 3 by the first screw 2, the other end of base plate 1 is provided with the second riser 4, one side of the first riser 3 is provided with eccentric center borehole jack 5, eccentric center borehole jack 5 is connected with nut 6, eccentric center borehole jack 5 is connected with a collet chuck 7 jointly with the inside of nut 6, the second riser 4 is connected with borehole jack 9 by the second screw 8, the outside of borehole jack 9 is connected with pressure head 10, pressure head 10 is connected with thin cylinder 11, eccentric center borehole jack 5 is staggered relatively with borehole jack 9, the outside of eccentric center borehole jack 5 and borehole jack 9 is equipped with two groups for top centre bore 14, the angle in every group switching centre hole 14 is 60 °.
Adopt for processing the method for the fixture machining cam axle of emergency pump camshaft, comprise the following steps:
The not eccentric excircle 12 at A, first machining cam shaft-like work two ends, then installs to camshaft workpiece 11 on fixture;
B, fixture is installed to together with camshaft workpiece to the top upper of numerically controlled lathe, two eccentric cam cylindricals 13 on machining cam shaft-like work respectively then, an eccentric cam cylindrical 13 of every group of corresponding centre bore 10 processing;
