a clamping fixture suitable for a valve block comprises a valve block positioning seat, a pull rod seat, a driving piece and a diagonal draw bar;
the middle part of the valve block positioning seat is provided with a cavity for accommodating a valve block to be clamped, the valve block positioning seat is fixed with the pull rod seat, and an inclined groove for the inclined pull rod to slide up and down is formed between the valve block positioning seat and the pull rod seat;
a pull ring is fixedly arranged in the middle of the driving piece, a groove is formed below the diagonal draw bar, the pull ring is embedded into the groove, and one end of the driving piece is fixed with the pull rod seat;
the driving piece drives the pull ring to move upwards, so that the diagonal draw bar slides along the chute, and the claw head loosens the valve block to be clamped;
the driving piece drives the pull ring to move downwards, so that the diagonal draw bar slides downwards along the chute, and the claw head clamps the valve block to be clamped.
Furthermore, a claw head is fixedly arranged above the diagonal draw bar.
Preferably, the claw head is a serrated claw surface.
Further, the driving member is an oil cylinder.
Furthermore, there are two diagonal draw bars, and the diagonal draw bar equipartition is in the chute.
Preferably, the two diagonal draw bars are oppositely disposed.
Compared with the prior art, the utility model discloses the beneficial effect who reaches:
the utility model discloses a clamping anchor clamps can improve the clamping efficiency of valve piece, easy and simple to handle, use manpower sparingly, reduce because of valve piece clamping position well lead to repeated clamping or strike the problem of correcting the valve piece perk, avoided the not hard up problem of valve piece. The requirement of parallelism and perpendicularity of the left side face and the right side face of the valve block, namely the clamping face, can be met after the valve block is clamped, and the risk of looseness in the machining process of the valve block is prevented. The utility model discloses realize from the centering function and prevent to wait to process the valve piece perk or not hard up.

Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example 1
A clamping fixture suitable for a valve block comprises a valve block positioning seat 4, a pull rod seat 5, a driving piece 7 and a diagonal draw bar 3;
the middle part of the valve block positioning seat 4 is provided with a cavity for accommodating the valve block 1 to be clamped, the valve block positioning seat 4 is fixed with the pull rod seat 5, and an inclined groove for the inclined pull rod 3 to slide up and down is arranged between the valve block positioning seat 4 and the pull rod seat 5;
a pull ring 6 is fixedly arranged in the middle of the driving piece 7, a groove is formed below the diagonal draw bar 3, the pull ring 6 is embedded into the groove, and one end of the driving piece 7 is fixed with the pull bar seat 5;
the driving piece 7 drives the pull ring 6 to move upwards, so that the diagonal draw bar 3 slides along the chute, and the claw head 2 loosens the valve block 1 to be clamped;
the driving piece 7 drives the pull ring 6 to move downwards, so that the diagonal draw bar 3 slides downwards along the chute, and the claw head 2 clamps the valve block 1 to be clamped.
The claw head 2 is fixedly arranged above the diagonal draw bar 3. The number of the diagonal draw bars 3 is two, and the diagonal draw bars 3 are uniformly distributed in the chute. The two diagonal draw bars 3 are oppositely arranged.
In the present embodiment, the claw head 2 is preferably a serrated claw surface. The serrated jaw surface is used for increasing the gripping force of the jaw head 2; the sawtooth claw surface is matched with the diagonal draw bar 3 to act, so that the grabbing and pulling effect is enhanced, the valve block can be prevented from loosening, and the position of the valve block is always fixed.
The driving member 7 in this embodiment is an oil cylinder.
The working principle is as follows:
the outer side surface (namely the clamping surface) of the valve block is arranged in a cavity of the valve block positioning seat, the machining switch is started, the hydraulic claw head automatically presses down to clamp the valve block, an operator checks the valve block to ensure that the positioning surface is flat, and the machining switch of the production equipment is started again to start machining. The two pull-down type inclined pull rods are respectively positioned at the left side and the right side of the valve block, and realize synchronous action of the two inclined pull rods under the pull-down action of a hydraulic oil cylinder below the valve block so as to complete self-centering positioning of the valve block; when the positioning surface tilts after clamping the valve block, the valve block is pulled back by downward oblique pulling force, namely the positioning surface of the valve block is attached to the positioning point of the clamp again, so that the problem of tilting of the valve block in the machining process is solved.
The utility model discloses a clamping anchor clamps can improve the clamping efficiency of valve piece, easy and simple to handle, use manpower sparingly, reduce because of valve piece clamping position well lead to repeated clamping or strike the problem of correcting the valve piece perk, avoided the not hard up problem of valve piece. The requirements of parallelism and perpendicularity of the clamping surface can be met after the valve block is clamped, and the risk of looseness in the machining process of the valve block is prevented. The utility model discloses realize from the centering function and prevent to wait to process the valve piece perk or not hard up.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
