Description

Technical Field

[0001] This utility model relates to the technical field of machining hole tooling, specifically to a tooling for machining large holes in a secondary valve body. Background Technology

[0002] The auxiliary valve body refers to the auxiliary shell structure that makes up the main body of the valve, mainly including the valve stem passage, the sealing packing cavity, and related connecting structures.

[0003] Due to the special shape of the secondary valve body, it is difficult to clamp it using traditional fixtures during the turning process. Usually, the operator has to use bolts or multiple clamping tools to clamp the secondary valve body. This clamping method is not only troublesome, but also unstable.

[0004] Therefore, there is currently a lack of specific clamping fixtures for the process of machining large holes in the secondary valve body. Utility Model Content

[0005] To solve the above problems, namely, to design a clamping fixture for machining large holes in secondary valve bodies, this utility model proposes a fixture for machining large holes in secondary valve bodies, which includes a main spindle end plate. The main spindle end plate is provided with a mounting plate and an upper pressure plate arranged parallel to each other. The valve body is bolted to the mounting plate and is disposed between the mounting plate and the upper pressure plate. A screw is threadedly connected to the upper pressure plate, and the screw abuts against the valve body.

[0006] A further feature of this invention is that the mounting plate has two through holes for inserting bolts, and the mounting plate is also provided with two positioning pins, the two through holes and the two positioning pins being arranged in a rectangular pattern.

[0007] A further feature of this invention is that the spindle end plate has two mounting slots for mounting the mounting plate and the upper pressure plate, respectively.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. The mounting plate enables the valve body to be quickly installed onto the spindle end plate, while the screws provide a clamping effect on the valve body, further enabling the valve body to be machined into larger holes more stably.

[0010] 2. By setting two locating pins and using two bolts, not only can the purpose of fixing and installing the valve body be met, but the valve body can also be quickly positioned, greatly shortening the clamping process of the valve body. Attached Figure Description

[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0015] refer to Figure 1 This utility model proposes a tooling for machining large holes in a secondary valve body, including a spindle end plate 1, which is mounted on the spindle of a lathe. A mounting plate 2 and an upper pressure plate 3 are bolted to the spindle end plate 1. The mounting plate 2 and the upper pressure plate 3 are arranged parallel to each other. A valve body 4 is bolted to the mounting plate 2 and is positioned between the mounting plate 2 and the upper pressure plate 3. A screw 31 is threaded onto the upper pressure plate 3. The lower end of the screw 31 abuts against the valve body 4 to achieve the purpose of pressing the valve body 4.

[0016] Two mounting slots 11 are provided on the spindle end plate 1. The two mounting slots 11 are arranged in parallel to each other. The mounting slots 11 are used to install the mounting plate 2 and the upper pressure plate 3. That is, the bottom of the mounting slot 11 is provided with a through hole 21. Bolts are threaded through the through hole 21 to connect with the mounting plate 2 and the upper pressure plate 3, thereby achieving the purpose of fixing the mounting plate 2 and the upper pressure plate 3 to the spindle end plate 1.

[0017] refer to Figure 2 The mounting plate 2 has two through holes 21 and two locating pins 22 welded to its surface near the upper pressure plate 3. The two through holes 21 and two locating pins 22 are arranged in a rectangle, with the two through holes 21 located at two opposite corners of the rectangle and the two locating pins 22 located at the other two opposite corners. Bolts are passed through the through holes 21 and the mounting holes on the valve body 4, and then nuts are threaded onto them to secure the valve body 4. The two locating pins 22 also engage with the mounting holes on the valve body 4 to position the valve body 4.

[0018] It should be noted that two side plates 5 are also provided between the mounting plate 2 and the upper pressure plate 3. The top of the side plates 5 are fixedly connected to the upper pressure plate 3 by bolts, and the bottom plate of the side plates 5 is fixedly connected to the mounting plate 2 by bolts, thereby improving the strength between the mounting plate 2 and the upper pressure plate 3. The valve body 4 is located between the two side plates 5.

[0019] In summary, this utility model enables the rapid installation of the valve body 4 onto the spindle end plate 1 via the mounting plate 2. Simultaneously, the screw 31 provides a clamping effect on the valve body 4, further stabilizing the large-hole machining process. By using two locating pins 22 in conjunction with two bolts, not only is the fixed installation of the valve body 4 achieved, but the rapid positioning process is also realized, significantly shortening the clamping process.
