Abstract
Wedge clamp in a kind of pawl type, it includes ontology, and handle is fitted into pawl fixture block, and pawl fixture block is connect by joint pin with ontology；It mixes pin to connect with spring base by screw thread, spring base is connect by soket head cap screw with ontology, and cylinder compression spring both ends are respectively arranged in the pit of pawl fixture block and spring base.Its big and for tubular part for cylindrical grinder clamp structure.
Description
Technical field
The utility model is related to a kind of machine tool accessories, wedge clamp in a kind of pawl type for cylindrical grinder is referred in particular to.
Background technology
Be presently used for cylindrical grinder clamping workpiece one is with heart carrier.Since heart card structure is not compact, volume
It is bigger than normal, it is unfavorable for installing and using for the short Shape Parts of major diameter, becomes hour in particular with grinding wheel diameter, clamp can go out with grinding wheel
Existing interference and collision phenomenon.Another is to use sleeve and screw fastening clamp mode, and defect is that screw port is easy to damage zero
Part surface.
Utility model content
The purpose of this utility model is to provide wedge clamp in a kind of pawl type, it is big for cylindrical grinder clamp structure and
It is compact-sized, small, easy to operate for the part of tubular.
In order to achieve the above objectives, the technical scheme adopted by the utility model is that：Wedge clamp in a kind of pawl type, it includes this
Body, handle are fitted into pawl fixture block, and pawl fixture block is connect by joint pin with ontology；Pin is mixed to connect with spring base by screw thread,
Spring base is connect by soket head cap screw with ontology, and cylinder compression spring both ends are respectively arranged in the pit of pawl fixture block and spring base
In.
The Operating pressure angle of the pawl fixture block is 20 °.
The working face toothing shape of the pawl fixture block, sawtooth angle are 60 °.
The handle is the soket head cap screws of M5 × 20.
The pin of mixing is the soket head cap screws of M5 × 40.
Wedge clamp is combined with using pawl one-way movement inversely locked and eccentric cam movement diameter change in this kind of pawl type
The operation principles such as change, the characteristic of this two technologies are combined together, and grinding force source is transferred on pawl fixture block, the two power
Directly proportional, grinding force is bigger, and clamping force also increases therewith.The working face toothing shape of pawl fixture block, is conducive to wedge.Through examination
It is reverse locked reliable with verification firm grip.Its big and for tubular part for cylindrical grinder clamp structure.With the prior art
It compares, has the positive effect that：It is compact-sized, small, easy to operate.
Description of the drawings
Fig. 1 is the main structure figure of the present embodiment.
Fig. 2 is that the right side of the present embodiment regards cut-away section structure chart.
Fig. 3 is the pawl fixture block main structure figure in the present embodiment.
Fig. 4 is that part A is amplified in Fig. 3.
In figure：1, handle, 2, joint pin, 3, ontology, 4, workpiece, 5, pawl fixture block, 6, cylinder compression spring, 7, interior hexagonal spiral shell
Nail, 8, spring base, 9, mix pin.
Specific implementation mode
The utility model is described again with reference to embodiment and its attached drawing.
Referring to Fig. 1-Fig. 3, wedge clamp in a kind of pawl type, it includes ontology 3, and handle 1 is fitted into pawl fixture block 5, pawl
Fixture block 5 is connect by joint pin 2 with ontology 3；It mixes pin 9 to connect with spring base 8 by screw thread, spring base 8 passes through soket head cap screw 7
It is connect with ontology 3,6 both ends of cylinder compression spring are respectively arranged in the pit of pawl fixture block 5 and spring base 8.On by screw 8 fix spine
Pawl 5, handle 1 are screwed into ontology 3 across pawl 5, are fixed by chain pin 2 on ontology 3, and bolt 7 is screwed into ontology 1,5 wedging driven disc of pawl
4 single direction rotations.
Referring to Fig. 1, the Operating pressure angle of the pawl fixture block 5 is 20 °.
Referring to Fig. 3 and Fig. 4, the working face toothing shape of the pawl fixture block 5, sawtooth angle is 60 °.
Referring to Fig. 1, the handle 1 is the soket head cap screws of M5 × 20.
Referring to Fig. 2, the pin 9 of mixing is the soket head cap screws of M5 × 40.
Referring to Fig. 1 and Fig. 2, when loading and unloading 4, handle 1 need to be only pulled to the right and compresses cylinder compression spring 6.Release handle
1, under the action of cylinder compression spring 6, compression pawl fixture block 5 is affixed to 4 inner surface of workpiece and stuck.
Wedge clamp is especially suitable for being clamped graden machine driven disc part in this kind of pawl type.
