Abstract
The utility model provides a front-mounted precise hydraulic contracting chuck, which relates to the field of clamping of a clamp for a machining part, and mainly solves the problems that the existing clamp clamping adopts a chuck type, the precision is low, repeated clamping precision of secondary machining cannot be ensured, the clamping reliability is poor, and the mounting is complex. The outer circumferential surface of a cylindrical main body is connected with a shell through a thrust bearing, the inner circle of the main body is provided with a piston with a horn mouth, the inner circle of the piston is provided with a snap spring, and the shell is fixedly provided with a positioning end cover for the shell and the snap spring. The front-mounted precise hydraulic contracting chuck is assorted with a machine tool spindle, so that the clamping precision of parts can be greatly improved, the centering effect is good, the repeated clamping precision is high, the operation is simple, the mounting is simple and fast, the clamping range is large, the safety performance is greatly improved, the clamping reliability is greatly improved, and the requirements for the machining precision of parts and compatibility of equipment to machining can be met.
Description
Technical field
The utility model relates to a kind of fixture clamping of machine tooling part, relates to specifically a kind of machining
Equipment, as the forward type precise hydraulic collet chuck of engine lathe, numerically controlled lathe, internal and external grinding machine etc.
Background technology
Mechanical processing industry, in to the process of circular pieces, must ensure the repeated clamping precision of secondary clamping of part and centering precision and safety, reliability, the manufacture of guarantee qualified products.What current fixture clamping adopted is chuck mode, and precision is low, cannot ensure the repeated clamping precision of secondary operations, and clamping poor reliability, without security, is installed complexity, especially low in production interchange Link Efficiency, can not adapt to the demand to part processing precision at present.
Summary of the invention
The purpose of this utility model is that the part clamping centering proposing for above-mentioned deficiency is effective, repeated clamping precision is high, simple to operate, and simple and fast is installed, clamping range is large, can meet precision and the compatible forward type precise hydraulic collet chuck of equipment to processing of part processing.
Technical solution of the present utility model is: the periphery of cylindrical-shaped main body is connected with shell by thrust bearing, in the inner circle of main body, be provided with one with bell-mouthed piston, in the inner circle of piston, be provided with jump ring, on shell, be fixed with the positioning end cover of shell and jump ring.
The inner circle of the main body described in technical solution of the present utility model is provided with step, and piston is positioned in main body by the step in main body inner circle and ring flange, between ring flange and piston, is provided with gap.
Shell described in technical solution of the present utility model and main body are provided with two oil fillers.
The utility model and machine tool chief axis are supporting, can greatly improve the clamping precision of part, feel relieved effective, and clamping range is larger than existing clamping mechanism, has met the requirement on machining accuracy of part.
The utility model is the following effect of tool also:
1. effectively reduce the clamping error in lathe, internal and external grinding machine production process;
2. improve the clamping efficiency in part production process;
3. improved the part clamping range of production equipment, allowed equipment there is better Products Compatibility;
4. install simpler, quick, accurate;
5. length positioning precision 0.02MM, part can make processing more succinct by secondary clamping;
6. part can not beaten and fly by fixture, and security performance significantly improves;
7. clamping reliability has very big lifting, the demand that the present production in enormous quantities of security compliance is manufactured.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, on the excircle of main body 1, be provided with shell 2, main body 1 is a circular cylinder body, between shell 2 and main body 1, be connected by two thrust bearings 3, main body 1 can be in the interior rotation of shell 2, along shell 2 and main body 1 be radially provided with two oil fillers 9,10, between shell 2 and main body 1, be provided with sealing ring 8, by sealing ring, 8 and two thrust bearings 3 realize tight storage; The inner circle of main body 1 is formed and is formed a step by two circles that vary in size, in the inner circle of main body 1, be provided with a piston 6, piston 6 is that an one end is with bell-mouthed cylinder, piston 6 is located piston 6 by the step in main body 1 and ring flange 5, between ring flange 5 and piston 6, be provided with gap, piston 6 can move vertically, and ring flange 5 is bolted in main body 1; Between piston 6 and main body 1, be provided with sealing ring 8, in the inner circle of piston 6, be provided with jump ring 7; In the outside of ring flange 5 along shell 2 be radially provided with end cap 4, end cap 4 is bolted on shell 2, by end cap 4, by shell 2 and jump ring 7 axial location, limit shell 2 slides axially; Operation principle: when use, main body 1 is connected with the ring flange on machine tool chief axis by the screwed hole 11 in main body 1, processing parts is fixed on jump ring 7 Inner circles, control respectively from oil-in 9 or oil-in 10 oil-feeds by Hydraulic Station magnetic valve, piston 6 is moved axially, when piston 6 moves right as shown in Figure 1, the conical surface of its bell-mouthed conical surface extruding jump ring 7, makes jump ring 7 shrink the part that clamps processing; After part processes, piston 6 is moved to the left as shown in Figure 1, the conical surface of the conical surface of piston 6 and jump ring 7 is thrown off, and opens by jump ring 7 self elasticity, unclamps part.
