The clamp comprises a substrate, wherein one end of the substrate is connected with a first vertical plate through a first screw, and the other end of the substrate is provided with a second vertical plate, and an eccentric centre hole bushing is arranged at one side of the first vertical plate and is connected with a screw cap; the eccentric centre hole bushing and the inner part of the screw cap are jointly connected with a contracting chuck, the second vertical plate is connected with a hole bushing through a second screw, and a pressure head is connected outside the hole bushing and is connected with a thin cylinder. The clamp provided by the utility model is complicate in structure, simple to manufacture and process, and high in precision.
Description
Technical field
The utility model relates to a kind of for processing the fixture of emergency pump camshaft.
Background technology
Generally all adopt the emergency pump safety guarantee of meeting an urgent need for large-tonnage automobile, existing emergency pump is all generally foreign-made, domestic not production, always be dependence import, after damage, change price higher, therefore domestic a lot of producer starts to carry out production and processing, general common process is difficult to realize, and needs the high special special equipment of price.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, and a kind of complex structure is provided, and manufactures processing simple, precision high for processing the fixture of emergency pump camshaft and using the method for its machining cam axle.
The purpose of this utility model 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 utility model is: the outside of described eccentric center borehole jack and borehole jack is equipped with two group switching centre holes.
Further improvement of the utility model is: described in every group, the angle of centre bore is 60 °.
The utility model compared with prior art has the following advantages: on the common apparatus such as numerically controlled lathe and common cylindrical grinder, manufacture camshaft, solve the dependence to special equipment, effectively reduced development cost, shortened the construction cycle, the camshaft precision after having manufactured is higher.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
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, not eccentric excircle, 13-eccentric cam cylindrical, 14-centre bore of 12-.
detailed description of the invention:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1, to show the utility model a kind of for processing the detailed description of the invention of 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 °.
The method that adopts fixture machining cam axle, comprises 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, then two eccentric cam cylindricals 13 on machining cam shaft-like work respectively, every group of corresponding centre bore 10 processed an eccentric cam cylindrical 13;
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 13 with identical before method.
The utility model is by adopting special fixture, on the common apparatus such as numerically controlled lathe and common cylindrical grinder, manufacture camshaft, solve the dependence to special equipment, development cost are effectively reduced, shorten the construction cycle, evade the risk of special equipment investment, fixture principle is as follows: respectively install a device with two centre bores additional at workpiece two ends, by the localization part of fixture, two centre bores with centre bore device are aligned mutually, and excircle of workpiece has very high precision relatively, this is to ensure by the structure of fixture and the accuracy of manufacture.When production, the not eccentric excircle at first machining cam axle two ends, loads onto fixture by workpiece after, and fixture band workpiece is installed to the top upper of numerically controlled lathe, processes respectively two eccentric cam cylindricals, and a cam cylindrical of each group switching centre hole processing is corresponding one by one; After heat treatment, also use fixture and the method for same structure, grind two cam cylindricals on plain external grinding machine, the camshaft precision after having manufactured is higher, and the eccentric throw error of camshaft is less than 0.03mm.
