Abstract
The present invention is non-rotary high speed through hole powered chuck and relates to universal clamp device widely used in mechanical field. The present invention has one annular hydraulic or pneumatic cylinder to move right and left as the power source, one annular piston pulling and pushing the guide annular block to drive one annular block to shift via one pair of centripetal thrust bearings, and one carriage on the chuck to drive the claws to move up and down, and can fasten and loosen the workpiece. All the annular cylinder, the annular piston, the guide block and the assembly do not rotate with the main shaft. The present invention has less parts rotating with the main shaft, less rotation mass, less oil/gas distribution, sealing, pressure retention, dynamic balance and other problems, easy standardized design and simple installation and use.
Description
Technical field
The present invention relates to be widely used in the universal fixturing of a class holding workpiece of mechanical field.
Background technology
Normal working power chuck on CNC lathe and automatic lathe, wherein hydraulic power chuck and pneumatic motive force chuck are most widely used.At present, the version of most of hydraulic power chucks and pneumatic motive force chuck is: the front end at lathe spindle is installed power chuck, and installs back rotatory force hydraulic pressure (air pressure) cylinder in the rear end of main shaft, and both connect by parts such as pull bars.When piston moved axially in hydraulic pressure (air pressure) cylinder, the claw that drives chuck moved up and down, thereby can clamp and unclamp workpiece.In addition, also there is a spot of power chuck and dynamicliquid pressure (air pressure) cylinder to be made of one, is installed in the front end of main shaft.The common structure feature of the power chuck of the above-mentioned type is: dynamicliquid pressure (air pressure) cylinder is helicoid, be revolution of dynamicliquid pressure (air pressure) cylinder cylinder body or piston revolution, because cylinder body or piston are with the lathe spindle high speed rotary, structure to hydraulic power chuck and pneumatic motive force chuck assembly has higher requirement, exist rotation at a high speed and join oil, distribution, sealing, difficult problems such as pressurize and dynamic balancing.
On September 28th, 1992, Wang Wanxiao has submitted " non-swinging type high-velocity through hole power oil cylinder " utility application to State Patent Office, and application number is 92220886.7,, and be awarded utility model patent on June 22nd, 1994.This patent has proposed a kind of oil cylinder body and piston all or not does not bear push-pull effort non-swinging type high-velocity through hole power oil cylinder with the bearing of main axis rotation and main shaft.This device have comparatively complicated clamping support and with the syndeton of piston.Simultaneously, still have supporting seat, part and the rotations of main shaft one superhigh speed such as support ring and pull bar.
Summary of the invention
The present invention is the deficiency that overcomes prior art, has proposed a kind of non-swinging type high-velocity through hole power chuck device, effectively reduces the quality with the main axis rotation part, overcome and join oil, distribution, sealing, difficult problems such as pressurize and dynamic balancing are easy to seriation and standardized designs manufacturing, are convenient to install and use.
In order to realize goal of the invention, the technical solution that the present invention proposes non-swinging type high-velocity through hole power chuck device comprises: ring-like power cylinder, ring-like piston, guide ring piece, the outer cover that gathering sill is arranged, one group of radial thrust bearing, ring-like push-and-pull slide block, slide and chuck body.Ring-like power cylinder, ring-like piston, guide ring piece be not with main axis rotation; Ring-like power cylinder at the front-end of spindle place adopts hydraulic pressure or air pressure as power source.The side-to-side movement under hydraulic pressure or gas pressure of ring-like power cylinder, the one group of radial thrust bearing that moves through of ring-like piston push-and-pull guide ring piece passes to ring-like push-and-pull slide block, the slide that oblique T type groove on the ring-like push-and-pull slide block causes being installed on the chuck body moves up and down, and slide drives claw and moves up and down the realization clamping and unclamp workpiece.
The present invention compared with the prior art, its technique effect is: ring-like power cylinder, ring-like piston etc. are all with main axis rotation, effectively reduce the quality with main axis rotation part quantity and rotation, simultaneously, because of ring-like power cylinder does not rotate, fuel feeding (gas) is convenient and simple, is easy to sealing and pressurize.Ring-like power cylinder can be directly installed on the main spindle box (not shown), helps improving the main shaft dynamic balancing, influences factor when simplifying the main shaft design.

The specific embodiment
In the structure shown in Figure 1, chuck body 29 is fixed on the main shaft 1 by connecting screw 30, and ring-like power cylinder assembly is fixed on the main spindle box (not shown) by connecting screw 11.Ring-like power cylinder assembly is made up of major parts such as piston rod 6, sealing ring 4,5,9,13, ring-like piston 8, ring-like power cylinder body 12 and cylinder caps 10; Guide ring piece and cover member by outer cover 15 and end cap 22, guide ring piece 16, connect main part such as screw rod 17 and constitute.Guide ring piece and outer cover group are by connecting with ring-like power cylinder assembly by connecting screw 14.Ring-like power cylinder assembly, guide ring piece and cover member be not with main axis rotation.When oil or gas enter in the ring-like power cylinder by fuel feeding (gas) hole 2 or 3, ring-like piston 8 and piston rod 6 move left and right, promotion is placed in guide ring piece 16 move left and right in the outer cover gathering sill, the motion of guide ring piece 16 then passes to ring-like push-and-pull slide block 23 by a pair of radial thrust bearing, and ring-like push-and-pull slide block passes to side-to-side movement the slide 28 that is installed on the chuck body chute by skewed slot, and slide 28 is moved up and down, cause claw to move up and down thus, realize clamping and unclamping workpiece.
Power cylinder among the present invention and piston are ring type, and guide ring piece 16 and push-and-pull slide block 23 also are ring type or are the combination ring type.Piston rod quantity in the ring-like power cylinder assembly is more than 2.
Ring-like power cylinder assembly among the present invention also can be installed in main spindle box inside (Fig. 6), and guide ring piece and cover member are directly installed on the main spindle box outside.
