The utility model discloses a cylinder sleeve-machining pneumatic liquid-plastic self-centering clamp comprising a cylindrical plunger, a sealing sleeve, a tubular core shaft, a tubular thin-wall sleeve, a tubular expansion sleeve, a sealing bolt and a power member connected with one end of the plunger, wherein a piston rod of the power member is coaxial with the plunger, the other end of the plunger is matched and connected with one end of the tubular core shaft through the sealing sleeve, the middle part of the core shaft passes through a tube hole of the thin-wall sleeve, the inner wall of the thin-wall sleeve is provided with a concave ring-shaped liquid-plastic cavity, the thin-wall sleeve passes through a tube hole of the expansion sleeve passing through the tube hole of a cylinder sleeve, the tube wall in the middle of the core shaft is provided with a through hole for communicating the liquid-plastic cavity and a core shaft cavity, and the sealing bolt is arranged at the other end of the core shaft and is matched and connected with a tube port. The cylinder sleeve-machining pneumatic liquid-plastic self-centering clamp is characterized in that the power member is a double-cylinder air cylinder, and the piston rod of the double-cylinder air cylinder is connected with the plunger through an elastic buffer member. As the power member is the double-cylinder air cylinder, the clamp has large clamping force; as the piston rod of the double-cylinder air cylinder has two restraining ring surfaces, the clamp has good centering performance; and as the piston rod is connected with the plunger though the elastic buffer member, the clamp has small impact force to the thin-wall sleeve when working.
Description
Technical field
The utility model belongs to the machining fixture technical field, relates to Liquid plastic clamp, particularly the pneumatic Liquid plastic clamp of cylinder jacket machined.
Background technology
It is liquid plastics that liquid is moulded, and as soft rubber, high resilience has certain fluidity again, can transmit identical pressure to all directions that it touched as liquid.Liquid is moulded strain that self-centering fixture moulds thin-walled cover by liquid and is clamped and unclamp workpiece, under normal operation, can guarantee the axiality of workpiece to be machined effectively.Liquid plastic clamp in the past mostly uses on hydraulic machine, does power with hydraulic pressure and carries out self-centering clamping, or use manual liquid to mould self-centering fixture on non-hydraulic lathe.
Existing cylinder sleeve machined liquid is moulded self-centering fixture, and its structure comprises cylindrical plunger, sealing shroud, tubulose mandrel, tubulose thin-walled cover, tubulose expansion set, the power spare that seals bolt, is connected with plunger one end; The piston rod of power spare is coaxial with plunger, the plunger other end is connected by sealing shroud and core tube's one end, the thin wall casing hole is passed at mandrel middle part; thin-walled cover inwall is provided with hollow toroid liquid and moulds the chamber; the thin-walled cover passes the expansion set pore; expansion set passes the cylinder sleeve pore, and mandrel middle part tube wall is provided with through hole and is communicated with liquid and moulds chamber and mandrel chamber, seals bolt and is located at the mandrel other end and is connected with the mouth of pipe; Power spare is a hydraulic cylinder or directly manual.
Adopt such technology certainly to reach the purpose that Liquid plastic clamp clamps, but having only under the compressed-air actuated workplace, as doing power spare with cylinder, there are the following problems: because the relative hydraulic cylinder of pneumatic cylinder pressure is less, generally at 0.8Mpa, single cylinder clamping power is big inadequately; Because the air pressure transmission speed is faster than hydraulic pressure, impulsive force is very big, and liquid to mould the thin-walled cover be to hold to can't stand long-term such impact; The centering balance of single cylinder cylinder piston rod such as badly just can't use.
The utility model content
The purpose of this utility model provides a kind of cylinder sleeve machined Pneumatic Liquid and moulds self-centering fixture, and clamping force is enough big when Liquid plastic clamp clamps, impulsive force is little, the centering balance is good.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: a kind of cylinder sleeve machined Pneumatic Liquid is moulded self-centering fixture, comprises cylindrical plunger, sealing shroud, tubulose mandrel, tubulose thin-walled cover, tubulose expansion set, the power spare that seals bolt, is connected with plunger one end; The piston rod of power spare is coaxial with plunger, the plunger other end is connected by sealing shroud and core tube's one end, the thin wall casing hole is passed at mandrel middle part; thin-walled cover inwall is provided with hollow toroid liquid and moulds the chamber; the thin-walled cover passes the expansion set pore; expansion set passes the cylinder sleeve pore, and mandrel middle part tube wall is provided with through hole and is communicated with liquid and moulds chamber and mandrel chamber, seals bolt and is located at the mandrel other end and is connected with the mouth of pipe; Power spare is the twin-tub cylinder, and the twin-tub cylinder is connected with plunger by the elastic force bolster.
Described elastic force bolster is an elastic force buffer shaft, and the elastic force buffer shaft comprises axle sleeve, spring; Axle sleeve is that an end is uncovered, the tubular body that the other end seals, and sealing end is connected with the piston rod of twin-tub cylinder is coaxial, and spring is arranged in the opening end body, and plunger one end is located in the opening end body and with spring and is abutted against.
The beneficial effects of the utility model are: because power spare is the twin-tub cylinder, it is big to exert oneself, and clamping force was just enough big when Liquid plastic clamp clamped; Because the cylinder piston rod of twin-tub cylinder has two constraint anchor rings, its piston rod of single cylinder cylinder is good to neutrality relatively; Because the piston rod of twin-tub cylinder is connected with plunger by the elastic force bolster, the impulsive force to the thin-walled cover during action is little.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.Wherein:
Fig. 1 is the schematic diagram of the utility model embodiment;
Fig. 2 is the schematic diagram of analysing of the utility model embodiment.
Marker number in the accompanying drawing is described as follows: sealing shroud 1, thin-walled cover 2, cylinder sleeve 3, expansion set 4, seal bolt 5, through hole 6, liquid and mould chamber 7, mandrel 8, plunger 9, spring 10, axle sleeve 11, twin-tub cylinder 12, piston rod 13
The specific embodiment
The utility model embodiment as shown in Figure 1 and Figure 2, a kind of cylinder sleeve machined Pneumatic Liquid is moulded self-centering fixture, comprises cylindrical plunger 9, sealing shroud 1, tubulose mandrel 8, tubulose thin-walled cover 2, tubulose expansion set 4, the power spare that seals bolt 5, is connected with plunger 9 one ends; The piston rod 13 of power spare is coaxial with plunger 9, plunger 9 other ends are connected by sealing shroud 1 and mandrel 8 pipes one end, mandrel 8 middle parts are passed thin-walled and are overlapped 2 pores; thin-walled overlaps 2 inwalls and is provided with hollow toroid liquid and moulds chamber 7; thin-walled cover 2 passes expansion set 4 pores; expansion set 4 passes cylinder sleeve 3 pores, and mandrel 8 middle part tube walls are provided with through hole 6 and are communicated with liquid and mould chamber 7 and mandrel 8 chambeies, seal bolt 5 and are located at mandrel 8 other ends and are connected with the mouth of pipe; Power spare is a twin-tub cylinder 12, and twin-tub cylinder 12 is connected with plunger 9 by the elastic force bolster.
