Abstract
The utility model relates to a thimble device, which comprises a cushion block, a deflector rod and a bolt. The cushion block and the deflector rod are fixed by the bolt, and the thimble device also comprises a centre sleeve which is fixed with the cushion block mutually through the bolt, the Morse taper of one end of the centre sleeve is matched with the Morse taper of a machine tool, and the other end is provided with a conicity which is matched with a processed part. The upper and the lower ends of the centre sleeve are symmetrically provided with a triangular prism shaped hard alloy block. Due to the adoption of the technical proposal, the deflector rod is connected with the centre sleeve into a whole by both being fixed with the cushion block, and the upper and the lower ends of the centre sleeve are symmetrically provided with the triangular prism shaped hard alloy block, thereby effectively preventing the punchy friction of the centre sleeve in the process of working, increasing the rigidity of the material at the head part of a thimble, reducing the distortion caused by a thimble head in the punchy contact of the thimble head and the processed workpiece, and greatly increasing the service life of the thimble.
Description
Technical field
The utility model relates to the push pin device that a kind of machining is used.
Background technology
Thimble is a machining frock commonly used, existing thimble in use, the thimble head with the powerful contact friction process of workpiece in be easy to be deformed wearing and tearing, whole thimble has just been scrapped.Apical axis and miscellaneous part also just can not re-use, and therefore the life-span of this thimble is very short.
Summary of the invention
The purpose of this utility model is to provide a kind of push pin device, uses this push pin device to have the following advantages: prevent the thimble head with the contact friction process of workpiece in the formation abrasion that produced, thereby increase the service life that increases thimble service life.
To achieve these goals, the technical solution adopted in the utility model is: a kind of push pin device, comprise cushion block, driving lever, screw, cushion block and driving lever are fixed by screw, also comprise center sleeve, and center sleeve interfixes by screw and cushion block, the Morse's taper of center sleeve one end and the Morse's taper of lathe match, the other end has the tapering that matches with processing parts, and driving lever and center sleeve link into an integrated entity by all fixing in cushion block, has improved resistance to wearing and the anti-vibration ability of thimble like this.
As a kind of improvement, described center sleeve is arranged with triangular prism shaped hard alloy blocks in two ends up and down, thereby the utility model is owing to strengthened thimble head material hardness and reduced because of the distortion that the thimble head is produced in contact with workpiece is powerful of thimble head, the while also alleviated the thimble head with the mutual friction mutually of workpiece.
As a kind of preferred, the tapering length that the tapering length of described hard alloy blocks matches greater than part, the cone angle of hard alloy blocks and the cone angle of part match.
The utility model is owing to adopt technique scheme, driving lever and center sleeve link into an integrated entity by all fixing with cushion block, center sleeve is symmetrical arranged triangular prism shaped hard alloy blocks in two ends up and down, effectively like this prevented centre head brute force friction in the course of the work, thereby made increase greatly the service life of thimble.
Description of drawings
Fig. 1 is the structural representation of the utility model push pin device.
The specific embodiment
Be shown a specific embodiment of the present utility model as Fig. 1, a kind of push pin device, comprise cushion block 2, driving lever 3, screw 4, cushion block 2 is fixing by screw 4 with driving lever 3, also comprise center sleeve 1, center sleeve 1 interfixes by screw and cushion block 2, and the Morse's taper of center sleeve 1 one ends and the Morse's taper of lathe match, and the other end has the tapering that matches with processing parts.Described center sleeve is arranged with triangular prism shaped hard alloy blocks 61 in two ends about in the of 1, the tapering length that the tapering length of hard alloy blocks 61 matches greater than part, and the cone angle of hard alloy blocks 61 and the cone angle of part match.The utility model is owing to adopt technique scheme, driving lever and center sleeve link into an integrated entity by all fixing in cushion block, center sleeve is symmetrical arranged triangular prism shaped hard alloy blocks in two ends up and down, effectively like this prevented centre head brute force friction in the course of the work, reduced because of the distortion that the thimble head is produced in contacting with workpiece is powerful of thimble head thereby strengthened thimble head material hardness, thereby made increase greatly the service life of thimble.
