Description

Technical Field

[0001] The utility model relates to a parts clamp, in particular to an insertion type overflow valve core clamp. Background Art

[0002] The valve core of the plug-in relief valve is an important component of the plug-in relief valve. During assembly, the valve core needs to be placed on the operating table first, and then other parts such as O-rings are installed. Currently, a single valve core is mainly placed on the operating table, and there is no special fixture for clamping and fixing. This will result in only one valve core being operated at a time, and the work efficiency is low; the valve core needs to be fixed by hand while other work is performed, which is troublesome to operate, and the valve core is prone to bumping, resulting in product waste. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an insertion-type overflow valve core clamp which has good clamping effect, is convenient for installing other parts on the valve core and can clamp multiple valve cores at one time.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: an inserted overflow valve core clamp, comprising a base plate, a fixed clamping plate, a movable clamping plate and a displacement driving mechanism, wherein the fixed clamping plate is fixedly arranged on the rear side of the base plate, the movable clamping plate is movably arranged on the base plate and located on the front side of the fixed clamping plate through the displacement driving mechanism, the upper part of the fixed clamping plate extends forward and is provided with a fixed clamping part, the upper edge of the front side of the fixed clamping part is laterally spaced and recessed with at least two first hexagonal splicing half holes, the lower part of the front side of the fixed clamping part protrudes forward to form a fixed splicing part, the A positioning circular hole is provided on the fixed splicing part below the first inner hexagonal splicing half-hole, and the upper rear part of the movable splicing plate protrudes backward to form a movable splicing part that cooperates with the fixed splicing part. The rear edge of the movable splicing part is laterally spaced and recessed to provide a number of second inner hexagonal splicing half-holes that are equal to and corresponding to the first inner hexagonal splicing half-holes. When the displacement driving mechanism drives the movable splicing plate backward so that the movable splicing part is spliced ​​above the fixed splicing part and abuts against each other, the first inner hexagonal splicing half-hole and the second inner hexagonal splicing half-hole are spliced ​​to form a complete inner hexagonal splicing hole.

[0005] The number of the first inner hexagon splicing half holes and the number of the second inner hexagon splicing half holes are both six, which further improves the assembly efficiency.

[0006] The displacement driving mechanism comprises at least two driving cylinders, the cylinder bodies of the driving cylinders are fixedly arranged on the bottom plate and located at the front side of the movable clamping plate, and the driving shafts of the driving cylinders are fixedly connected to the front side of the movable clamping plate at the rear. The number of driving cylinders can be selected according to actual needs to ensure the stability of clamping.

[0007] Compared with the prior art, the utility model has the advantage that the positioning circular hole of the fixed clamping part is used to pre-insert and position the bottom of the plug-in relief valve core, and when the displacement driving mechanism drives the moving clamping plate backward to make the moving splicing part spliced ​​on the top of the fixed splicing part and abut against each other, the first inner hexagonal splicing half hole and the second inner hexagonal splicing half hole are spliced ​​to form a complete inner hexagonal splicing hole, and the outer hexagonal structure of the plug-in relief valve core itself is fixed, and then the plug-in relief valve core is assembled, such as installing components such as O-rings. After the assembly is completed, the switch of the driving cylinder is turned off, and the driving gas is driven. The cylinder drives the movable clamping plate to move forward and separate from the fixed clamping part, and finally the plug-in relief valve core is removed to complete a round of assembly; the plug-in relief valve core can be effectively fixed by cooperating with the fixed splicing part and the movable splicing part to form a complete inner hexagonal splicing hole, which makes assembly more convenient and improves work efficiency. In addition, the parts are fixed during assembly, which improves product processing quality and has high safety and reliability. The clamp can clamp at least two valve cores at the same time, is easy to operate, and reduces the labor intensity of workers. A conventional guide mechanism can be set between the movable clamping plate and the base plate to ensure the accuracy of the moving direction. BRIEF DESCRIPTION OF THE DRAWINGS

When the displacement drive mechanism drives the mobile splicing plate 3 backward to splice the mobile splicing part 31 above the fixed splicing part 24 and abut against each other, the first hexagonal splicing half hole 22 and the second hexagonal splicing half hole 32 are spliced ​​to form a complete hexagonal splicing hole. The displacement drive mechanism is two driving cylinders 4, and the cylinder body of the driving cylinder 4 is fixedly arranged on the bottom plate 1 and located at the front side of the mobile splicing plate 3. The driving shaft of the driving cylinder 4 is fixedly connected to the front side of the mobile splicing plate 3. The driving cylinder 4 can also be selected in greater numbers as needed to maintain a stable clamping effect.

[0012] During actual operation, the bottom of the inserted relief valve core is placed into the positioning circular hole 23 of the fixed clamping part 21, and then the switch of the driving cylinder 4 is turned on. The driving rod pushes the movable clamping plate 3 to move. When the displacement driving mechanism drives the movable clamping plate 3 backward so that the movable splicing part 31 is spliced ​​on the top of the fixed splicing part 24 and abuts against each other, the first inner hexagonal splicing half hole 22 and the second inner hexagonal splicing half hole 32 are spliced ​​to form a complete inner hexagonal splicing hole and fix the corresponding outer hexagonal structure on the inserted relief valve core. Then, the inserted relief valve core is assembled, such as installing components such as O-rings. After completing the assembly, the switch of the driving cylinder 4 is turned off, and the driving cylinder 4 drives the movable clamping plate 3 to move forward and separate from the fixed clamping part 21. Finally, the inserted relief valve core is removed to complete a round of assembly.
