Description
Technical field
This utility model relates to a kind of chuck, particularly relates to a kind of high-precision machine chuck.
Background technology
Lathe is that main lathe tool carries out the lathe of turnery processing to the workpiece rotated.Lathe can also be used with drill bit, reamer, reamer, screw tap, screw die and checkering tool etc. process accordingly.Lathe, also known as lathe, uses the workman of lathe to be referred to as " turner ", and in mechanical processing industry, lathe is considered as the work " machine tool " of all devices.The parts that mainly comprise of lathe have: main spindle box, change gear box, feed box, slip crate, knife rest, tailstock, feed rod, leading screw, lathe bed, cabinet base and chiller.
Chuck is for clamping the machinery of workpiece on lathe.Utilize moving radially, Workpiece clamping and the machine tool accessories of location of the movable jaw being distributed on chuck body.Chuck is typically made up of chuck body, movable jaw and claw drive mechanism 3 part.Minimum 65 millimeters of chuck body diameter, maximum up to 1500 millimeters, there are through hole in central authorities, in order to by workpiece or bar；There are cylinder or short taper profile structure in back, is connected with machine tool chief axis end directly or by ring flange.Chuck is typically mounted on lathe, cylindrical grinder and internal grinder use, it is possible to coordinate with various indexing means, for milling machine and drilling machine.
Scroll chuck is as the important component part on horizontal lathe, and it moves radially Workpiece clamping and location mainly by three movable jaws being distributed on chuck body.The claw of existing scroll chuck is usually regular length, owing to claw radical length is inadequate, scroll chuck is when grabbing workpiece, easily occur capturing shakiness, cause workpiece to come off from claw or add the situation that off normal occurs man-hour, in prior art, the length increasing claw realizes typically by again making whole claw, and production cost is higher and complex process.Furthermore, traditional chuck is moved up and down by pull bar drivening rod, then is driven claw radially slide to realize the clamping to workpiece or unclasp by connecting rod, and claw exists connecting rod during regulation and drives this intermediate link, and regulation process is the most direct.
Utility model content
In order to solve, the claw length of existing scroll chuck is inadequate, regulate the roundabout defect of process, and this utility model spy provides a kind of high-precision machine chuck.
The technical solution of the utility model is as follows:
A kind of high-precision machine chuck, the flat spiral shell dish being arranged in chuck body including bevel pinion, chuck body and rotation, chuck body is provided with three chutes, three chutes are respectively separated 120 ° of settings, and chute slides is provided with claw；The bottom of flat spiral shell dish is provided with bevel gear, and described bevel pinion is radially arranged along chuck body and is meshed with bevel gear；Claw uses flat thread structure to be connected with flat spiral shell dish, and the top of flat spiral shell dish offers flat thread, and claw offers the screw thread matched with flat spiral shell dish；Described claw is away from being provided with lengthening part on one end of chuck body.In this programme, when rotating bevel pinion, the flat spiral shell dish being engaged with will rotate, and claw uses flat thread structure to be connected with flat spiral shell dish, and flat spiral shell disc spins will drive three claws close to chuck hub or exits.In this programme, claw is similar with the operation principle of leading screw and nut mechanism with the operation principle that flat spiral shell dish uses flat thread structure to be connected, it is possible to by convert rotational motion for moving along a straight line.In this programme, only need to can control tightening up and loosening of claw by rotating bevel pinion, easy to adjust fast.Furthermore, the setting of lengthening part achieves the lengthening to claw, solves and the most easily occurs because of claw length capturing unstable and causing workpiece to come off or add occurring man-hour the situation of off normal to occur.
As preferred structure of the present utility model, described lengthening part offers receiving chamber, claw be arranged in receiving chamber away from one end of chuck body and with accommodate chamber interference fit.In this programme, lengthening part and claw interference fit so that lengthening part is easy for installation and is difficult to slide.
Further, the front end face of described lengthening part is provided with cushion block.In clamping process, only first cushion block grind rotten after could wear and tear lengthening part, therefore the setting of cushion block effectively increases the service life of lengthening part.
For this utility model is better achieved, the material that described cushion block and claw use is carbon structural steels.The plasticity of carbon structural steels, toughness, cold deformation performance are good, in this programme, cushion block and claw are made by carbon structural steels, when making cushion block, claw and absorption surface can not disfiguring workpiece, ensure that cushion block and claw have simultaneously and enough add holding force, improve the clamping stability of chuck.
Further, the front end face of described cushion block is provided with slip-resistant texture.Slip-resistant texture adds and contacts friction between cushion block with workpiece so that cushion block can firmly grasp object to be processed.
Further, the outside of described chuck body is provided with chuck retaining ring.In the course of processing of lathe, some is deposited in around chuck body by the iron filings cut, and due to the quick rotation of chuck body, iron filings will fly out everywhere, chuck body outer surface easily producing abrasion or damages, the setting of chuck retaining ring adds the service life of chuck body.
For this utility model is better achieved, lengthening part offering screwed hole A, the sidewall of claw is equidistantly provided with several screwed holes B, lengthening part is connected by screw with claw.In this programme, lengthening part is connected by screw with claw so that together with lengthening part is tightly attached to claw, is difficult to loosen.Equidistantly it is provided with several screwed holes B on the sidewall of claw so that the length of lengthening part correspondingly can regulate according to the situation of workpiece to be held, adds the suitability of chuck in this utility model.
In sum, Advantageous Effects of the present utility model is as follows:
1, claw and flat spiral shell dish use the bevel gear that flat thread structure is connected, bevel pinion is arranged with flat spiral shell tray bottom to be meshed, and can control tightening up and loosening of claw by rotation bevel pinion, easy to adjust fast.
2, the setting of lengthening part achieves the lengthening to claw, solves and the most easily occurs because of claw length capturing unstable and causing workpiece to come off or add occurring man-hour the situation of off normal to occur.
3, lengthening part and claw interference fit so that lengthening part is easy for installation and is difficult to slide.
4, in clamping process, only first cushion block grind rotten after could wear and tear lengthening part, therefore the setting of cushion block effectively increases the service life of lengthening part.
5, cushion block and claw are made by carbon structural steels so that when cushion block, claw and absorption surface can not disfiguring workpiece, ensure that cushion block and claw have simultaneously and enough add holding force, improve the clamping stability of chuck.
6, slip-resistant texture adds and contacts friction between cushion block with workpiece so that cushion block can firmly grasp object to be processed.
7, the setting of chuck retaining ring adds the service life of chuck body, it is to avoid the iron filings being deposited in around chuck body fly out everywhere and chuck body outer surface produce abrasion or damages.
8, lengthening part is connected by screw with claw so that together with lengthening part is tightly attached to claw, is difficult to loosen.
9, equidistantly it is provided with several screwed holes B on claw sidewall so that the length of lengthening part correspondingly can regulate according to the situation of workpiece to be held, adds the suitability of chuck in this utility model.
