Description

Quick clamp for machining oil grooves of plane gasket

Technical Field

The utility model relates to a processing technology equips, especially relates to a quick anchor clamps of plane gasket oil groove processing.

Background

The planar gasket is a gasket with two planar end faces, is widely applied to various machines, and is mainly used for bearing pressure, adjusting distance and the like, but under some special conditions, the planar gasket is also required to bear abrasion caused by relative motion. In order to improve the above problems, it is a better technical means to provide oil grooves on two end surfaces of the planar gasket. As shown in fig. 4 and 5, an arc-shaped oil groove 2 ' is provided on an upper end surface of a gasket body 1 ' of the planar gasket, an arc-shaped oil groove 3 ' is provided on a lower end surface of the gasket body 1 ', the oil groove 2 ' and the oil groove 3 ' are both communicated with an inner circumferential wall 4 ' and an outer circumferential wall 5 ' of the gasket body 1 ', the oil groove 2 ' and the oil groove 3 ' are respectively composed of two symmetrically-arranged arc-shaped oil grooves, the two symmetrically-arranged arc-shaped oil grooves of the oil groove 2 ' are arranged on the same circumference, the two symmetrically-arranged arc-shaped oil grooves of the oil groove 3 ' are arranged on the same circumference, and the oil grooves 2 ' and the oil grooves 3 ' on two end surfaces are arranged on two circumferences with opposite eccentric directions (as shown in fig. 4). Usually, the oil groove needs to be processed by a processing center, but the processing cost is high, the processing efficiency is low, and the requirement of mass production of the plane gasket is not met. The patent document with publication number 204997424U discloses a turning clamp for an oil groove of a planar gasket, which adopts a compression nut to compress the planar gasket, and since the compression nut needs to be manually screwed by an operator, although the workload of the operator is reduced to a certain extent, and the labor intensity is reduced, the working efficiency is still low, and the production requirement of the planar gasket produced in large batch is still difficult to meet.

SUMMERY OF THE UTILITY MODEL

The applicant carries out research and improvement aiming at the problems, provides a quick clamp for machining the oil grooves of the planar gasket, has a simple and compact structure, is convenient and quick to operate, further improves the production efficiency, reduces the workload of workers, reduces the production cost, and meets the requirement of mass production of the planar gasket.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a rapid clamp for machining an oil groove of a planar gasket comprises a disc-shaped clamp body, wherein a positioning boss for positioning an inner hole of the planar gasket is arranged at the front end of the clamp body, the clamp body is provided with an inner hole coaxial with the positioning boss, a guide key is fixedly arranged on the side wall of the inner hole, a supporting plate is arranged in the inner hole in a sliding mode, and a key groove matched with the guide key is formed in the supporting plate; the pneumatic finger is eccentrically arranged and fixedly connected with the supporting plate, 2 symmetrically arranged pressing plates are respectively and fixedly connected with 2 finger ends of the pneumatic finger, and the pressing plates are in a crescent shape; the rear end of the clamp body is fixedly provided with a support, the pressing cylinder is fixedly arranged on the support, and a piston rod of the pressing cylinder is fixedly connected with the supporting plate.

The technical effects of the utility model reside in that:

the utility model discloses a quick fixture of plane gasket oil groove processing, simple structure is compact, and convenient operation is swift, further improves production efficiency, reduces workman's work load, and reduction in production cost satisfies plane gasket mass production's demand.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1, 2, 3, the utility model discloses a anchor clamps body 1 of disc, the front end of anchor clamps body 1 is equipped with the location boss 3 that is used for the location plane gasket hole, anchor clamps body 1 is equipped with the hole 101 coaxial with location boss 3, the fixed setting of direction key 6 is on the lateral wall of hole 101, layer board 5 slides and sets up in hole 101, be equipped with the keyway that matches with direction key 6 on the layer board 5, hole 101 slides including layer board 5 can, and prevent layer board 5 from rotating for the sliding guide of layer board 5 by direction key 6. Pneumatic finger 4 eccentric settings and fixed connection layer board 5, the eccentric volume that pneumatic finger 4 set up is the same with the eccentric volume of oil groove on the plane gasket, 2 the clamp plate 2 of 2 symmetry settings respectively fixed connection at 2 finger ends of pneumatic finger 4, clamp plate 2 is the crescent moon shape. The rear end of the clamp body 1 is fixedly provided with a support 8, a pressing cylinder 7 is fixedly arranged on the support 8, and a piston rod of the pressing cylinder 7 is fixedly connected with the supporting plate 5.

During the in-service use, press from both sides the anchor clamps body 1 on the chuck of lathe, when initial condition, the piston rod that compresses tightly cylinder 7 is in the state of stretching out, 2 fingers of pneumatic finger 4 are in the state of retracting to the centre, pack into the location boss 3 of the 1 front end of the anchor clamps body with plane gasket 9 this moment, operate pneumatic finger 4, 2 fingers of pneumatic finger 4 outwards open, 2 clamp plates 2 that the symmetry set up outwards open simultaneously, then operation compresses tightly cylinder 7, the piston rod that compresses tightly cylinder 7 retracts and drives layer board 5, pneumatic finger 4 and 2 clamp plates 2 retract together, the clamp plate compresses tightly plane gasket 9, can process the oil groove on the plane gasket 9 this moment. After the oil groove is machined, the pneumatic finger 4 and the pressing cylinder 7 are operated reversely, and then the plane gasket 9 can be taken down. Whole operation process convenient and fast further improves production efficiency, reduces workman's work load, and reduction in production cost satisfies the demand of plane gasket mass production.
