[0036] The following will be combined with the attached embodiment of the present invention Figure 1-14 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example

[0038] like Figures 1 to 14 As shown, this embodiment discloses an efficient and convenient ball valve assembly tool. This method is mainly aimed at a special assembly tool for a three-piece ball valve, including

[0039] A fixed clamp block 5a; it can be fixedly mounted on a support, and the support can be adapted with a rotation function, which can realize rotation in the direction, so as to meet the needs of the processor and improve convenience. The scheme is as follows:

[0040] A movable jaw block 1a is arranged opposite to the fixed jaw block and can be moved away from or closer to the fixed jaw block by movement; a movable jaw block lower threaded hole is opened at the lower end of the movable jaw block, and the corresponding fixed jaw block is also opened with a fixed jaw block threaded hole, and the two are directly equipped with a screw rod, and a hand wheel is arranged outside the screw rod, and the movable jaw block is controlled by the forward and reverse operation of the hand wheel to move closer to or away from the fixed jaw block.

[0041] A fixed block 2, which has two fixed devices, a left fixed block fixed on the movable clamp block and a right fixed block set on the fixed clamp block; the fixed block added in this scheme is used in conjunction with the clamp block to facilitate processing and maintenance. In order to install the scheme, the left fixed block and the right fixed block are fixedly installed on the movable clamp block and the fixed clamp block by screws 1. The fixed block 2 and Figure 3 The jaw iron 4a in the embodiment is the same component and is fixedly installed by means of a screw rod 1 or 1a.

[0042] A clamping block 7, two clamping blocks are provided, located between the left fixed block and the right fixed block, and a storage space is formed between the two clamping blocks as a placement area for the object to be processed; the shape of the clamping block can be diverse, and this solution adopts:

[0043] In the above, reference Figure 5 The two clamping blocks 7 are respectively provided with clamping block through holes (through holes) on the same side end faces, and the fixed block is provided with a fixed block hole (blind hole) which is communicated with the clamping block through holes. A movable shaft 4 is arranged in the clamping block through hole, and the movable shaft extends out of the clamping block through hole and extends into the fixed block hole. The two clamping blocks can use the movable shaft as a rotation fulcrum, so that the two clamping blocks can be in different positions.

[0044] The movable shaft is also covered with an axis spring 3, and the axis spring can be used to quickly remove the ball valve after the assembly is completed.

[0045] The clamp block is divided into a left clamp block and a right clamp block, and the left clamp block and the right clamp block are installed in a symmetrical form. The symmetrical installation can provide assembly accuracy and improve the product qualification rate.

[0046] The left clamp block is provided with a left clamp block outer edge plate facing the right clamp block, and the upper end surface of the left clamp block outer edge plate serves as a left slideway 8. The left clamp block is also provided with an upper limit outer edge, which is located above the left clamp block outer edge plate. By adding a slideway, the objects to be processed can be stored in different positions or sizes, that is, the objects to be processed can be moved in a certain direction, with a high degree of matching.

[0047] In order to further improve the stability of the product, a right clamp block outer edge plate is provided on the right clamp block facing the left clamp block, and the upper end surface of the right clamp block outer edge plate serves as a right slideway. A first upper limit outer edge is also installed on the right clamp block, and the first upper limit outer edge is located above the right clamp block outer edge plate.

[0048] The first upper limit outer edge and the two faces of the upper limit outer edge are partially empty on the left slide and the right slide. That is, when some of the objects to be processed need to be fixed in the upper position, it is only necessary to move the objects to be processed along the slide to the bottom of the first upper limit outer edge and / or the upper limit outer edge to achieve the purpose of limit locking, further improve stability, and also improve processing accuracy.

[0049] Among them, a limiting block 6 is provided on the left clamp block and / or the right clamp block to prevent excessive turning. The limiting block of the present scheme is connected to the column spring 5. Under normal conditions, the limiting block is located on the outer end surfaces of the movable clamp block and the fixed clamp block for limiting. If a large rotation angle is required, the column spring 5 can be compressed by a tool. This can increase the rotation of the left clamp block and / or the right clamp block, and can realize adjustment of different clamping angles of the left clamp block and the right clamp block, with wider applicability.

[0050] Further explanation of the assembly tooling of this scheme:

[0051] The preparation method is as follows:

[0052] Step a: Drill a through hole in the movable clamp body and a blind hole in the fixed clamp body. Figure 5 , punch a through hole in the movable clamp body, punch a blind hole in the fixed clamp body, and the through hole and the blind hole constitute the above-mentioned fixed block hole;

[0053] Step b: Assemble the clamp into the vise (fixed jaws and movable jaws)

[0054] Install the stopper and column spring onto the fixed jaw block and the movable jaw block, and then fix the custom jaw iron [2] to the movable jaw body and the fixed jaw body through the hexagon socket bolt [1]. Then place the clamp block and the spring of the shaft between the two clamp blocks, and pass the movable shaft through the through hole of the clamp block until it reaches the blind hole. When completed, it will be as shown in the figure*.

[0055] Step c: Use a fixture to assemble the three-piece ball valve. The specific assembly method is as follows:

[0056] Put the valve cover into the slide rail, such as Figure 7 After completion, Figure 8 ;

[0057] Then put in the hexagonal bolts, such as Fig. 9 After completion, Fig.10 ;

[0058] Flip the clamp, such as Fig.11After completion, Fig.12 ;

[0059] Then install other parts of the three-piece ball valve. Fig.13 ;

[0060] Finally, tighten the bolts and nuts with a wrench. Fig.14 .

[0061] The invention has a simple structure, but the market has not adopted the tooling of this type, which well solves the current manual assembly problem.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
