Description

Technical field:

[0001] The utility model relates to the technical field of valve body equipment, and more specifically to a clamp for processing multiple valve bodies. Background technology:

[0002] Some existing relay valves, ABS valves and other valve bodies for automobiles need to be clamped during the processing and then processed. When the hole to be processed is an oblique hole, the valve body of the relay valve, ABS valve and the like needs to be tilted. However, there is no corresponding clamping tooling, and the valve body can only be clamped after a plurality of fixing blocks are fixed to each other. Only a single valve body can be clamped, which is inefficient and has poor effect. Moreover, after each clamping, the inclination angle of the valve body is constant. When the processed inclination angle is not accurate and the inclination needs to be slightly changed, it cannot be adjusted and can only be adjusted by adding an inclination pad or the like. The adjustment is very troublesome, with poor effect and low efficiency. Utility model content:

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a clamp for processing multiple valve bodies, which can clamp and fix multiple valve bodies and adjust the inclination angle of the valve bodies as needed to ensure processing accuracy and is easy to adjust.

A vertical screw sleeve 15 is screwed on the vertical screw 14. The bottom end of the vertical screw sleeve 15 is movably connected to the lower support seat 22 via a hinge shaft.

[0021] Furthermore, side baffles 16 are fixed to the front and rear of the top surface of the fixed base plate 10, a plurality of cylindrical mounting heads 17 are fixed to the rear wall surface of the front side baffle 16, a plurality of screw-through holes are formed on the rear side baffle 16, an adjusting screw 161 is screwed into the corresponding screw-through holes, and a front end of the adjusting screw 161 extends out of the rear side baffle 16 and faces the corresponding cylindrical mounting head 17.

[0022] A rotating handle is fixed on the outer side wall of the radially extending edge 151 .

[0023] A radially extending limiting edge 171 is formed on the outer side wall of the front end of the cylindrical mounting head 17 .

[0024] The rear end of the adjusting screw 161 extends out of the rear side baffle 16 and is fixed with a rotating part. The front end of the adjusting screw 161 is fixed with a pressing plate 162 .

[0025] The adjusting screw rod 161 is threaded with a locking nut 3 , and the locking nut 3 is pressed against the rear wall surface of the rear side baffle 16 .

[0026] When this embodiment is in use, the valve body to be processed can be placed on the corresponding cylindrical mounting head 17, and the corresponding cylindrical mounting head 17 extends into the corresponding mounting through hole of the valve body, and the limiting edge 171 presses against the corresponding outer side wall of the valve body, loosens the corresponding locking nut 3, rotates the adjusting screw 161, so that the pressing plate 162 presses against the other end face of the valve body, and then loosens the corresponding locking nut 3 to complete the fixation.

[0027] At the same time, a limit block 30 is fixed below the cylindrical mounting head 17 of the front side baffle 16, and a screw-connected positioning through hole is formed in the middle of the limit block 30. The screw portion of the lower side adjusting bolt 31 is screwed in the corresponding screw-connected positioning through hole, and one end of the screw portion of the lower side adjusting bolt 31 extends out of a side wall of the limit block 30. A side locking nut 32 is screwed on the screw portion of the lower side adjusting bolt 31, and the end face of the side locking nut 32 is closely attached to a side wall of the corresponding limit block 30. By loosening the side locking nut 32 and rotating the screw portion of the lower side adjusting bolt 31, the end of the screw portion is pressed against the corresponding lower side wall of the valve body, thereby achieving further limiting and improving the fixing accuracy.

[0028] The left and right parts of the two side baffles 16 are provided with connecting screws 9 extending forward and backward, the ends of the connecting screws 9 extend out of the outer side walls of the corresponding side baffles 16 and are screwed with outer locking nuts 4, the connecting screws 9 are located on the inner side of the corresponding side baffles 16 and are screwed with inner locking nuts 5, and the side baffles 16 are clamped between the corresponding inner locking nuts 5 and the outer locking nuts 4.

The bottom end of the compression spring 1 forces the top surface of the radially extending edge 151, and the top end of the compression spring 1 forces the bottom edge of the upper rotating seat 13.

[0030] A wear-resistant layer 2 is fixed to the top surface of the radially extending edge 151 , and the bottom end of the compression spring 1 is pressed against the top surface of the wear-resistant layer 2 .

[0031] In this embodiment, the radially extending edge 151 can be rotated by holding the rotating handle to adjust the distance between the vertical screw 14 and the vertical screw sleeve 15, thereby changing the inclination of the fixed base plate 10 to meet the inclination requirements of the processing. The adjustment is convenient and the adjustment accuracy is high.

[0032] Moreover, the compression of the compression spring 1 makes it difficult for the vertical screw sleeve 15 to rotate when the rotating handle is not rotated.

[0033] This embodiment can clamp and fix multiple valve bodies. It can be used for processing on processing equipment with multiple connectors, and can also be processed at a single processing head. During the processing, after one valve body is completed, this embodiment can be moved so that another valve body can be processed accordingly, which is convenient for continuous processing. In addition, the inclination angle of the valve body can be adjusted as needed to ensure processing accuracy, and it is easy to adjust.
