Abstract

The utility model discloses a pneumatic indexing fixture base, comprising a fixture base body, a jacket, a movable piston arranged in the fixture base body and an index plate arranged on the top surface of the base body. The inner hole of the index plate is connected with the outer circumference of the jacket, the circumference of the top surface of the index plate is uniformly distributed with a plurality of index holes, and the index holes are provided with index screw bolts. The top surface of the fixture base body is provided with positioning holes corresponding to the index holes, the outer circumference of the index plate is provided with screw holes at intervals for installing throw rods, index throw rods are arranged in the screw holes, the side wall of the fixture base body is provided with horizontal through holes communicated with the inner holes of the base body, and locking handles are arranged in the through holes. When the pneumatic indexing fixture base is utilized, workpieces in clamping state require indexing, the locking handles at the side wall of the base body can be loosened, the index throw rods on the outer circumference of the index plate can be pulled to cause the index plate to drive the jacket connected with the index plate and an elastic fixture to rotate to indexing position, and then the locking handles are locked for next processing.

Description

A kind of steam-operating calibration base of the carrier head

Technical field

The utility model relates to anchor clamps, is specifically related to a kind of steam-operating calibration base of the carrier head.

Background technology

In the prior art, there be a kind of being specifically designed to that part is clamped, again with machinery to its steam-operating base of the carrier head of processing, be provided with in the steam-operating base of the carrier head and drive piston, the chuck that collet moves up and down, existing steam-operating base of the carrier head does not have the calibration function, if desired during calibration, need to take out workpiece, clamp long, the effort of taking a lot of work of operating time, inefficiency after rotating adjustment again.

The utility model content

The purpose of this utility model is, a kind of steam-operating calibration base of the carrier head is provided, and can carry out quick index to the workpiece in the chuck when workpiece is in clamped condition, improves working (machining) efficiency.

The technical scheme that the utility model provides is as follows: construct a kind of steam-operating calibration base of the carrier head, comprise the chuck pedestal, chuck, be arranged on the mobile piston in the chuck pedestal, also comprise the index dial that is arranged on described pedestal end face, the endoporus of described index dial is connected with the protrusion excircle of described chuck, on the end face periphery of described index dial, be evenly equipped with a plurality of index holes, in each index hole, be equipped with the calibration bolt, end face at described chuck pedestal is provided with the locating hole corresponding with described index hole, on the excircle of described index dial, be interval with the screw that is used to install throw rod, in screw, be provided with the moving bar of index plate, on the sidewall of described chuck pedestal, be provided with the horizontal through hole that is communicated with the pedestal endoporus, in through hole, be provided with lock handle.

The utlity model has following advantage: when using steam-operating calibration base of the carrier head, when workpiece is in clamp position and needs calibration again, can unclamp the lock handle on the pedestal sidewall, pull the calibration tommy bar on the index dial excircle, the collet that makes index dial drive the chuck of fixedlying connected with it rotates, behind the arrival indexing position, again lock handle is locked, can carry out next step processing, improve the operating efficiency of calibration, alleviate working strength.

Description of drawings

Fig. 1 is the sectional structure schematic diagram of the utility model steam-operating calibration base of the carrier head.

The specific embodiment

With reference to Fig. 1, a kind of steam-operating calibration base of the carrier head is provided, comprise chuck pedestal 7, chuck 3, be arranged on the mobile piston 9 in the chuck pedestal 7, present body sidewall is provided with and promotes the air admission hole 8,9 that piston moves up and down; Also comprise the index dial 4 that is arranged on pedestal 7 end faces, the endoporus of index dial 4 is connected with the protrusion excircle of chuck 3, on the end face periphery of index dial 4, be evenly equipped with a plurality of index holes 2,5, at each index hole 2, all be provided with calibration bolt 13 in 5, end face at chuck pedestal 7 is provided with the locating hole corresponding with index hole 702, on the excircle of index dial 4, be interval with the screw 1 that is used to install throw rod, 6, at screw 1, be provided with the moving bar 12 of index plate in 6, on the sidewall of chuck pedestal 7, be provided with the horizontal through hole 701 that is communicated with pedestal endoporus 703, in through hole, be provided with lock handle 11.

When using steam-operating calibration base of the carrier head, when workpiece is in clamp position and needs calibration again, can unclamp the lock handle 11 on the pedestal sidewall, pull the calibration tommy bar 12 on the index dial excircle, the collet that makes index dial 4 drive the chuck 3 of fixedlying connected with it rotates, when calibration bolt 13 enters locating hole 702 on next chuck pedestal 7 end faces, behind the arrival indexing position, with lock handle 11 lockings, can carry out next step processing again to workpiece.
