Authorization Notice No. discloses a kind of fixture for grinding machine for the Chinese utility model patent of CN202317979U, including rectangular The ontology of body shape, the side of ontology be vertically connected with can height up and down block, it is parallel that the other side is vertically connected with two Fixed block is provided with screw rod fixed block between two fixed blocks, threaded hole is provided on screw rod fixed block, and be fixed with by threaded hole Fastening screw.Part is placed on the body when processing, and leans against the inside of block, is firmly pushed up part by turn screw rod Tightly.

The fixture for grinding machine is by longer fastening screw retaining element, since its structure is longer, and with the contact surface of part Product is small, and stability is bad, so that part is loosened because of vibrations when easily occurring in grinding machine work, influences its processing.

Utility model content

In view of the deficiencies of the prior art, the utility model aim is to provide a kind of fixture for grinding machine, there is clamping to consolidate, no The advantages of easily loosening.

To achieve the above object, the utility model provides the following technical solutions：

A kind of fixture for grinding machine, including pedestal and the opposite fixture block of both direction, offer on the pedestal for the folder The guide groove of block sliding clamping；Two fixture blocks, which abut, drive rod, and the middle part of two drive rods turns with the pedestal Dynamic connection；Sliding abuts between two drive rods a wedge block, and the wedge block is abutted to have and be connect with the pedestal Screw rod, being connected between the wedge block and the pedestal makes it keep the spring abutted with the screw rod.

So set, by rotating screw rod, make it that wedge block be pushed to be moved into pedestal, to drive two drive rods will Two fixture blocks are moved toward one another along guide groove, and realization clamps part；When not unclamping screw rod, fixture block can keep stable state, Part is clamped to realize, ensures not loosen when grinding machine works, ensures processing quality.

Further setting：It is provided in the pedestal for accommodating two drive rods and being connected to the guide groove Cavity.

So set, by being arranged drive rod in the cavity of pedestal, reducing the part being exposed at outside pedestal, making entire The structure of fixture for grinding machine is compacter, reduces volume.

Further setting：The fastening bolt for wearing the cavity is plugged in the middle part of two drive rods.

So set, two drive rods are hinged by fastening bolt, fixture block is pushed under the drive of wedge block to realize The action of Clamp blocks；It is easy to disassemble simultaneously.

Further setting：Two Z-shaped settings of drive rod, reinforcing rib is provided at its dog-ear.

So set, it is Z-shaped by the way that drive rod to be arranged, to increase the stroke of drive rod and fixture block contact jaw so that Fixture for grinding machine can adapt to the larger part of change in size；The setting of reinforcing rib increases the structural strength of drive rod, can Enough bear the pressure of bigger and, to enable fixture for grinding machine to apply the clamping force of bigger to part, ensure that the clamping of part is steady It is fixed.

Further setting：The limit hole for the screw rod grafting is offered on the wedge block.

So set, by the way that screw rod is inserted into limit hole, to which the end face for preventing wedge block and screw rod from abutting against occurs Sliding, ensures the kinematic accuracy of wedge block.

Further setting：It is provided with regular polygon on the end face that the screw rod is located at the pedestal outer end, for spanner card The forced section connect.

So set, by adding forced section, convenient for rotating screw rod with spanner, spanner achievees the effect that rapid operation.

Further setting：The screw rod is connected with handle.

So set, by connecting handle, so that it is driven screw rod rotation convenient for pulling handle, reach the effect of rapid operation Fruit.

Further setting：Be located in the screw rod end face of the pedestal outer end on offer the jack of regular polygon, One end of the handle is provided with the connector with the jack grafting.

So set, the connection of the jack and connector by regular polygon, to realize that handle drives screw rod rotation, simultaneously Handle can be pulled up after Clamp blocks, it is made not interfered at work with grinding machine.

In conclusion the utility model has the advantages that：

1. driving fixture block by drive rod, the firm clamping to part is realized under the action of screw rod and wedge block；

2. fixture for grinding machine is simple and compact for structure, simple operation is laborsaving.
