[0016] The preferred embodiments of the utility model will be described below with reference to the drawings, and those skilled in the art should understand that these embodiments are only used to explain the technical principles of the utility model, and are not intended to limit the protection scope of the utility model.
[0017] Referring to Figures 1 to 5 , the utility model embodiment discloses a kind of 3D printing complex valve body structure's combination tooling mainly includes fixed shaft 1, mounting plate 2, operating plate 3 and display device, overall the tooling in this technical solution needs two different forms to cooperate, which contains fixed shaft 1 and mounting plate 2 arranged on fixed plate, fixed shaft 1 is same with mounting plate 2 in specification, easy to align, fixed shaft 1 is clamped using clamp, and as the support structure of entire tooling, fixed shaft 1 guarantees stability when using, mounting plate 2 is coaxially arranged with fixed shaft 1, is cylindrical, easy to be clamped and fixed, reduce operation difficulty, operating plate 3 is detachably connected with mounting plate 2, easy to operate and adjust, operating plate 3 is used to fixed valve body, forms support to valve body.
[0018] The display device has two settings. In the preliminary processing, the display device on the operation plate 3 used first includes positioning columns 4 arranged on the upper surface for positioning. The positioning columns 4 are arranged in four to ensure the accuracy of the valve body processing. After the first step of processing part of the valve body, the second display device is used. The positioning shaft 201 is arranged in the middle position of the mounting plate 2. The diameter of the positioning shaft 201 is smaller than that of the fixed shaft 1, which is used for positioning the center of the positioning shaft 201, facilitating the alignment, and is used for printing the accurate positioning of the valve body. A plurality of positioning holes are additionally arranged on the operation plate 3 to reduce the position error generated during the two production processes and improve the processing accuracy.
[0019] In the processing, first, the valve body is processed by milling to form the bottom surface and the positioning hole, ensuring that the valve body has a preliminary geometric shape and a positioning reference. Then, the valve body is positioned and fixed by the tooling one with the positioning columns 4. The four protruding cylinders on the tooling one cooperate with the positioning holes of the valve body to ensure the accurate positioning of the valve body. Then, the machine tool processes the left side hole of the valve body to ensure the accuracy and coaxiality of the left side hole. After completing the processing of the left side hole, the valve body is transferred to the combined tooling two (display device with positioning shaft 201) for positioning. The cylindrical part of the combined tooling two cooperates with the processed hole on the left side of the valve body to ensure the coaxiality of the valve body during the secondary processing. At the same time, the movable block is used to fix the valve body and is fixed with the rotary tooling. On the tooling, the display device (which can be the positioning column 4 or the positioning hole) on the operation plate 3 cooperates with the corresponding part of the valve body to further ensure the accurate positioning of the valve body. Then, the machine tool processes the right side hole of the valve body and the groove in the hole to meet the requirements of coaxiality and roughness.
[0020] Four positioning columns 4 are arranged on the operation plate 3. These positioning columns 4 cooperate with the positioning holes on the valve body to ensure the accurate position of the valve body during the processing. The number and position of the positioning columns 4 can be adjusted according to the specific structure of the valve body. The positioning holes are arranged on the operation plate 3, and the positioning shaft 201 is arranged along the axis in the middle position of the mounting plate 2. The corresponding part of the valve body cooperates with the positioning shaft 201 and the positioning hole to achieve accurate positioning. It is suitable for scenes where the valve body has corresponding protruding structures, solves the alignment problem of complex valve bodies during multiple processing, ensures the processing accuracy and coaxiality, and realizes the high-precision manufacturing of the valve body through the preprocessing, preliminary processing and secondary processing steps of the valve body, ensuring the use effect and improving the processing accuracy.
