Abstract

The utility model relates to a fixture body, in particular to a chuck structure for processing a shaft type standard component. The chuck structure for processing the shaft type standard component comprises a chuck body. The chuck structure for processing the shaft type standard component is characterized by further comprising oil transportation cavities which are evenly arranged on the side wall of the inner circle of the chuck body and the oil transportation cavities divide the chuck body into three equal portions. The chuck structure for processing the shaft type standard component further comprises clamps which are arranged in the oil transportation cavities. The diameter of an excircle cross section of the front half portion of the clamp is slightly smaller than the diameter of an excircle cross section of the back half portion of the clamp, the whole body of the clamp is in a step type structure, the back half portion of the clamp tightly matches with the side wall of the oil transportation cavity, a gap is arranged between the front half portion of the clamp and the side wall of the oil transportation cavity. An annular protrusion which is used for stopping the clamp from sliding from the oil transportation cavity and is arranged in a place of the side wall of the oil transportation cavity, and the place is close to the outlet. Compared with the prior art and due to the adoption of the hydraulic theory to clamp the shaft type standard component, the chuck structure for processing the shaft type standard component avoids the appearance of phenomena of too big clamping force or too small clamping force in the process of clamping parts, not only guarantees human safety of operators, but also guarantees production quality, and reduces reject rate.

Description

The chuck structure of working shaft-like standard component

Technical field

The utility model relates to a kind of clamp body, specifically a kind of chuck structure of working shaft-like standard component.

Background technology

When the working shaft-like standard component, the general scroll chuck that adopts is fixed clamping to axle class standard spare, existing scroll chuck generally needs to adopt in addition guide cone to insert the bellmouth of scroll chuck, by the rotary steering cone claw on the scroll chuck is moved, until clamping work pieces, and the rotary steering cone generally all adopts manually-operated, is easy to occur the too little or excessive situation of chucking power, the too little meeting of chucking power causes workpiece to jump out in process, can cause potential safety hazard to the operative employee; Chucking power is too large, can cause surface of the work to stay the clamping vestige, and serious may cause workpiece deformation in process.

Summary of the invention

The utility model is in order to overcome the deficiencies in the prior art, and a kind of axle class standard spare chuck structure of simple in structure, easy to operate, good clamping effect is provided.

To achieve these goals, the utility model has designed a kind of chuck structure of working shaft-like standard component, comprises chuck body, it is characterized in that: also comprise the oil transportation chamber that is distributed on the chuck body inner ring sidewall, the oil transportation chamber is divided into three equal parts with chuck body, also comprises the clamp that is arranged in each oil transportation chamber; The cylindrical diameter of section of described clamp first half is slightly less than latter half of cylindrical diameter of section, clamp integral body is staircase structural model, and the latter half of and sidewall oil transportation chamber of clamp closely cooperates, the sidewall in first half and oil transportation chamber has certain gap, and the nearly exit of the sidewall in oil transportation chamber is provided for stopping the annular protrusion that clamp skids off in the oil transportation chamber.

Comprise that also the position that cooperates each oil transportation chamber is arranged on the oil transfer joint of chuck body upper surface.

The end of described clamp also is provided with metal hard-sealing.

The afterbody of described clamp is with circular-arc bulge-structure.

The utility model is compared with prior art, because the principle that adopts hydraulic pressure is come clamp axis class standard spare, cancelled the mode of original artificial clamping, avoided workpiece in clamping process, the appearance of the too large or too little situation of its chucking power, not only guaranteed operating personnel's personal safety, and guaranteed product quality to have reduced percent defective.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the schematic diagram of clamp motion among Fig. 1.

Fig. 3 be in the utility model clamp in the view of holding workpiece.

Referring to Fig. 1 to Fig. 3,1 is chuck body; 2 are the oil transportation chamber; 3 is clamp; 4 is annular protrusion; 5 is oil transfer joint; 6 is metal hard-sealing; 7 is bulge-structure; 8 is workpiece; 9 is hydraulic oil.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, the utility model comprises chuck body 1, also comprise the oil transportation chamber 2 that is distributed on the chuck body 1 inner ring sidewall, oil transportation chamber 2 is divided into three equal parts with chuck body 1, also comprise the clamp 3 that is arranged in each oil transportation chamber 2, the upper surface of chuck body 1 cooperates the position in each oil transportation chamber 2 also to be provided with oil transfer joint 5; The cylindrical diameter of section of these clamp 3 first halfs is slightly less than latter half of cylindrical diameter of section, clamp 3 integral body are staircase structural model, and latter half of and sidewall oil transportation chamber 2 of clamp 3 closely cooperates, the sidewall in first half and oil transportation chamber 2 has certain gap, the end of this clamp 3 also is provided with metal hard-sealing 6, can avoid damaging to workpiece, the afterbody of clamp 3 is with circular-arc bulge-structure 7, and the nearly exit of the sidewall in oil transportation chamber 2 is provided for stopping the annular protrusion 4 that clamp 3 skids off in the oil transportation chamber 2.As shown in Figure 2, when clamp 3 during to the Way out motion certain distance in oil transportation chamber 2, annular protrusion 4 just in time is fastened on the latter half of of clamp 3, avoids clamp 3 to skid off in oil transportation chamber 2 when motion.

Specific operation process is as follows:

As shown in Figure 3, during work, hydraulic oil 9 is filled in oil transfer joint 5 is sent to oil transportation chamber 2 by oil pump, clamp 3 applies clamping force to the cylindrical of workpiece 8 under the pressure-acting of hydraulic oil 9, thereby realizes purpose that workpiece 8 is carried out clamping.

Compare with prior art, because the principle that adopts hydraulic pressure is come clamp axis class standard spare, cancelled the mode of original artificial clamping, avoided workpiece in clamping process, the appearance of the too large or too little situation of its chucking power, not only guaranteed operating personnel's personal safety, and guaranteed product quality to have reduced percent defective.
