Disk processes part, the early investment higher cost of equipment frock, and easily breaks down in use, and maintenance cost is high,
Increase the processing cost of part.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of centrifugal chuck, is started and stopped using lathe
When sliding plate itself inertia force realize part retaining and release, lathe stop after recycle spring be restored to claw initially
Location status reduces being loaded the time for part without manual or other power mechanisms, and it is strong to reduce operator's labour
Degree, improves processing efficiency, to reduce production cost.
The utility model is realized in this way a kind of centrifugal chuck, including terminal pad, disk, sliding plate, claw and outer cover,
Terminal pad is fixed on lathe spindle front end, and disk is fixed in terminal pad, is gap face contact between sliding plate and disk, and pass through
A piece spring connection, the outer round surface of sliding plate are equipped with circumferential groove, and fixed briquetting is installed on disk, and briquetting extend into groove
It is interior, sliding plate is limited in the rotary motion that certain angle is done in disk, claw one end is U-shaped groove structure, and the other end is clamping end,
3 straight pins are uniformly fixed on disk, straight pin extension end is inserted into the U-lag of claw, and sliding plate is equipped with pin hole, pin shaft
Claw is connected with sliding plate clearance fit across pin hole, rotate claw can around pin shaft, outer cover is connected by screw on pin shaft.
Further, the face that the disk is contacted with the sliding plate is equipped with arc groove A, and the sliding plate connects with the disk
The face of touching is equipped with arc groove B, arc groove A and arc groove B and is correspondingly formed a circumferential circular channel, and the spring setting exists
In the circular channel.
Further, the terminal pad is fixed by screws on lathe spindle, and the disk is fixed by screws in company
It connects on disk.
Compared with the prior art, the advantages of the utility model are: solving manual clamping by the simple fixture of structure
Cumbersome repetitive operation with workpiece is unclamped, significantly improves processing efficiency, reduces labor intensity.It in addition can be different by replacement
Claw go to realize the processing of other diameter axle type parts, replace corresponding terminal pad for the different lathe of model, increase
Use scope and applicability.
Detailed description of the invention
With reference to the accompanying drawing and embodiment is described in further detail the utility model:
Fig. 1 is the utility model positive structure schematic；
Fig. 2 is the A-A the schematic diagram of the section structure of Fig. 1；
Fig. 3 is the B-B the schematic diagram of the section structure of Fig. 1；
Fig. 4 is utility model works structural schematic diagram.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Case is described in further details the utility model.It should be appreciated that specific implementation case described herein is used only for solving
The utility model is released, is not used to limit the utility model.
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model provides a kind of centrifugal chuck, including terminal pad 1, disk 2, sliding plate 3,
Claw 4 and outer cover 5, terminal pad 1 are fixed on 10 front end of lathe spindle, and disk 2 is fixed in terminal pad 1, and sliding plate 3 is with disk 2
Gap face contact, and connected by a spring 6, the outer round surface of sliding plate 3 is machined with circumferential groove, installs on disk 2
Fixed briquetting 7, briquetting 7 are extend into groove, and sliding plate 3 is limited in the rotary motion that certain angle is done in disk 2, claw 4 one
End is U-shaped groove structure, and the other end is clamping end, and 3 straight pins 8 are uniformly fixed on disk 2, and 8 extension end of straight pin is inserted into
In the U-lag of claw 4, sliding plate 3 is equipped with pin hole, and pin shaft 9 passes through pin hole and connects claw 4 with 3 clearance fit of sliding plate, makes claw
4 can rotate around pin shaft 9, and outer cover 5 is connected by screw on pin shaft 9.
When carrying out clamping to workpiece using the utility model, machine tool chief axis 10 and 15 part of platform urosome install main shaft top first
Point 11 and platform tail centre 16, centrifugal chuck are mounted on machine tool chief axis 10, guarantee that terminal pad 1 is fitted closely with main shaft end face, so
The workpiece 12 that centre bore is accomplished fluently at both ends is placed between spindle top 11 and platform tail centre 16 afterwards, after by the centre bore of workpiece 12
Be directed at machine tool chief axis top 11 and platform tail centre 16, by mobile station urosome 15 make workpiece be fixed on two it is top between, start machine
Bed rotates main shaft 10, and lathe spindle 10 drives the terminal pad 1 of centrifugal chuck and disk 2 to rotate counterclockwise, and sliding plate 3 is made because of inertia
Relative motion is generated with disk 2, claw 4 is stirred by the straight pin 8 being mounted on disk 2 and clamps workpiece, passes through lathe tool 14
Workpiece is processed.Because the clamping face of claw 4 is eccentric arc, so cutting force is bigger, workpiece 12 just holds tighter.Parking
When, because the inertia force of sliding plate 3 itself drives claw 4 to unclamp workpiece, lathe recycles spring to be restored to claw 4 initially after stopping
Location status.
If desired when lathe spindle rotates clockwise progress turning, the spring 6 (having preformed hole) and card in centrifugal chuck
Pawl 4 does reversed installation.
It is mounted on a kind of specific embodiment on centrifugal chuck as spring 6, the disk 2 is contacted with the sliding plate 3
Face be equipped with arc groove A, the face that the sliding plate 3 is contacted with the disk 2 is equipped with arc groove B, arc groove A and arc groove B
It is correspondingly formed a circumferential circular channel, a spring 6 is arranged in the circular channel.
As a kind of specific connection type, the terminal pad 1 is fixed by screws on lathe spindle 10, the disk
2 are fixed by screws in terminal pad 1.
