Description

Technical Field

[0001] This utility model relates to the field of valve processing equipment technology, and more specifically, to a rotary tooling for ball valve processing. Background Technology

[0002] During the manufacturing process of ball valves, especially when precision machining is performed on key parts such as the internal flow channels and sealing surfaces of the valve body, it is necessary to ensure that the workpiece can be positioned stably and accurately, and can be flexibly rotated and adjusted according to the processing requirements.

[0003] Based on the above, the inventors have discovered that traditional tooling fixtures often suffer from problems such as low positioning accuracy, cumbersome clamping, and insufficient stability. This leads to workpiece misalignment or wobbling during machining, affecting not only the accuracy of machining dimensions and surface quality but also potentially reducing production efficiency and increasing product defect rates due to repeated clamping. Furthermore, some tooling is difficult to adapt to the machining requirements of different ball valve specifications, exhibiting poor versatility. This necessitates frequent tooling changes when changing product models, further increasing production and time costs. Therefore, in view of this, the inventors have researched and improved existing structures to provide a rotary tooling for ball valve machining, aiming to achieve greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a rotary tooling for ball valve processing. It can effectively solve the problems of low positioning accuracy, cumbersome clamping, insufficient stability, and poor versatility of traditional tooling fixtures in ball valve processing. Through a precise positioning structure and a stable clamping method, it ensures that the workpiece is not easily shifted or shaken during processing, thereby improving the accuracy of processing dimensions and surface quality. At the same time, it simplifies the clamping process, reduces repeated clamping time, improves production efficiency, reduces product defect rate, and can adapt to the processing requirements of ball valves of different specifications, reducing the frequency of tooling changes, thereby reducing the production cost and time cost of enterprises.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A rotary tooling for ball valve processing includes a fixing module, a clamping module, and a workpiece body. A positioning block is fixedly connected to the bottom center of the fixing module, and a lower positioning shaft is fixedly connected to the bottom of the positioning block. An upper positioning shaft is fixedly connected to the top center of the clamping module. A lower valve body fixing plate is fixedly connected to the top of one end of the fixing module, and an upper valve body fixing plate is fixedly installed at the bottom of one end of the clamping module. The valve body portion of the workpiece body is disposed between the fixing module and the clamping module, and the valve seat portion of the workpiece body is disposed between the lower valve body fixing plate and the upper valve body fixing plate.

[0009] Furthermore, the lower positioning axis and the upper positioning axis are set on the same axis.

[0010] Furthermore, the fixing module and the clamping module have the same structure, and both have a bayonet on their adjacent sides.

[0011] Furthermore, the two bayonet arc-shaped structures are used, and the valve body of the workpiece body is engaged between the two bayonet slots.

[0012] Furthermore, the lower valve body fixing plate has the same structure as the upper valve body fixing plate, and the two are arranged symmetrically.

[0013] Furthermore, both the lower valve body fixing plate and the upper valve body fixing plate have positioning holes on their respective sides that are close to each other, and the valve seat of the workpiece body is engaged between the two positioning holes.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) This solution uses a fixing module and a clamping module, with a bayonet between them to clamp and position the valve body of the workpiece. Simultaneously, the positioning ports on the lower and upper valve body fixing plates provide double-limiting for the valve seat of the workpiece. Combined with the coaxial arrangement of the lower and upper positioning shafts, a multi-dimensional precision positioning structure is formed, effectively improving the positioning accuracy of the ball valve workpiece and avoiding the dimensional deviations caused by inaccurate positioning in traditional tooling. During clamping, the valve body and valve seat of the workpiece are simply placed between the bayonet and positioning port respectively to complete the initial positioning. Stable clamping is then achieved through the clamping module. The entire clamping process is simple and convenient, greatly simplifying the cumbersome clamping steps of traditional tooling, reducing the time required for repeated clamping, and thus significantly improving production efficiency.

[0017] (2) This solution uses the bayonet setting of the fixing module and the clamping module, and adds a replaceable lower valve body fixing plate and upper valve body fixing plate, so that the tooling can adapt to the processing requirements of ball valve bodies and valve seats of different diameters and lengths, which enhances the versatility of the tooling. When changing ball valve products of different specifications, enterprises do not need to frequently change the tooling. They only need to adjust some positioning parts of the existing tooling, thereby reducing the frequency of tooling replacement and reducing the production cost and time cost caused by tooling replacement.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Example:

[0035] Please see Figures 1-4 A rotary tooling for ball valve processing includes a fixing module 1, a clamping module 2, and a workpiece body 8. A positioning block 3 is fixedly connected to the bottom center of the fixing module 1, and a lower positioning shaft 4 is fixedly connected to the bottom of the positioning block 3. An upper positioning shaft 5 is fixedly connected to the top center of the clamping module 2. A lower valve body fixing plate 6 is fixedly connected to the top of one end of the fixing module 1, and an upper valve body fixing plate 7 is fixedly installed at the bottom of one end of the clamping module 2. The valve body part of the workpiece body 8 is disposed between the fixing module 1 and the clamping module 2, and the valve seat part of the workpiece body 8 is disposed between the lower valve body fixing plate 6 and the upper valve body fixing plate 7.

[0036] See Figure 2 The lower positioning shaft 4 and the upper positioning shaft 5 are set on the same axis.

[0037] See Figure 1 The fixing module 1 and the clamping module 2 have the same structure, and both have a bayonet 9 on their adjacent sides.

[0038] See Figure 4 The two bayonet 9 have an arc-shaped structure, and the valve body of the workpiece body 8 is engaged between the two bayonet 9.

[0039] See Figure 4 The lower valve body fixing plate 6 and the upper valve body fixing plate 7 have the same structure and are symmetrically arranged.

[0040] See Figure 4 The lower valve body fixing plate 6 and the upper valve body fixing plate 7 are both provided with positioning ports 10 on their respective sides, and the valve seat of the workpiece body 8 is engaged between the two positioning ports 10.

[0041] Working Principle: In use, firstly, the fixing module 1 is installed onto the rotary fixture via the positioning block 3 and the lower positioning shaft 4. Then, the valve body of the workpiece 8 is placed in the bayonet 9 of the fixing module 1, while ensuring that the valve seat of the workpiece 8 is correspondingly embedded in the positioning port 10 of the lower valve body fixing plate 6. Subsequently, the bayonet 9 of the clamping module 2 is aligned with the upper side of the valve body of the workpiece 8, so that the positioning port 10 of the upper valve body fixing plate 7 covers the upper side of the valve seat of the workpiece 8, achieving initial positioning of the workpiece 8. Next, the clamping module 2 is moved towards the fixing module 1 by an external drive and a certain pressure is applied until the clamping module 2 and the fixing module 1 firmly clamp the workpiece 8. At this time, the lower positioning shaft 4 and the upper positioning shaft 5 are on the same axis, and the entire fixture can be installed on the rotary table of the processing equipment via the lower positioning shaft 4 and the upper positioning shaft 5. When the machining equipment drives the rotary table to rotate, the lower positioning shaft 4 and the upper positioning shaft 5 drive the fixing module 1, the clamping module 2, and the clamped workpiece body 8 to rotate synchronously, thereby rotating less than or equal to 360 degrees along the axes of the lower positioning shaft 4 and the upper positioning shaft 5. This enables continuous machining operations on different angles and different parts of the workpiece body 8 until all machining is completed. When machining ball valves of different specifications, the lower valve body fixing plate 6 and the upper valve body fixing plate 7 with corresponding positioning ports 10 can be replaced according to the valve body diameter and valve seat size to meet diverse machining needs.
