Description

Technical Field

[0001] This utility model belongs to the field of valve body assembly technology, and more specifically, it relates to a tooling fixture for irregularly shaped valve bodies. Background Technology

[0002] Irregular valve body tooling fixtures are specialized clamping devices designed for valve bodies with complex and irregular shapes. Common types include hydraulic chuck type, pressure plate type, support positioning type, and shaft pin type. They achieve stable clamping of irregular valve bodies through specific positioning structures and clamping mechanisms, such as hydraulic drive, pressure plate clamping, multi-directional support, and shaft pin positioning, to meet the accuracy and efficiency requirements of machining processes such as turning, drilling, and milling.

[0003] Based on the above, the tooling fixtures currently in use adopt a fixed installation structure for positioning, which makes it inconvenient to adjust the position of the valve body workpiece during positioning, resulting in weak applicability and making it difficult to adjust the working state as needed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a non-standard valve body tooling fixture, which solves the problem mentioned in the background art that existing tooling fixtures use fixed installation structures for positioning, making it inconvenient to adjust the position of the valve body workpiece during positioning, resulting in weak applicability and difficulty in adjusting the working state as needed.

[0005] The purpose and effect of this utility model's irregularly shaped valve body tooling fixture are achieved through the following specific technical means: A tooling fixture for an irregularly shaped valve body includes a base, a mounting platform fixedly mounted on the top of the base, and two sets of clamping frames fixedly mounted on the top side of the mounting platform. The corners of the clamping frames are all beveled, and hydraulic pistons are fixedly mounted inside the beveled surfaces of each clamping frame. L-shaped plates are fixedly mounted on the telescopic ends of the hydraulic pistons. Guide buckles are fixedly mounted at the corners of adjacent surfaces of the two sets of clamping frames, and the L-shaped plates slide within the guide buckles. Miniature electric cylinders are fixedly mounted at the corners of the L-shaped plates, and pulley frames are fixedly mounted on the telescopic ends of the miniature electric cylinders. Two sets of positioning pulleys are rotatably mounted within each pulley frame.

[0006] Furthermore, positioning clamps are fixedly installed at the turning points of the L-shaped plate, and corrugated grooves are opened in the middle of the adjacent surfaces of the four sets of positioning clamps.

[0007] Furthermore, electrode rods are embedded at both ends of the L-shaped plate, and the micro electric cylinder is connected to the electrode rods by wiring.

[0008] Furthermore, brushes are provided on both sides of the inside of the guide buckle, and the brushes are in contact with the electrode rod.

[0009] Furthermore, a hydraulic pump is fixedly installed on the top of the base, and one end of the hydraulic pump is connected to the hydraulic piston via an oil circuit.

[0010] Furthermore, a hydraulic oil bladder is fixedly installed on the top of the base, and the hydraulic oil bladder is connected to one end of the hydraulic pump.

[0011] Compared with the prior art, the present invention has the following beneficial effects: Solving the positioning and adjustment problem and improving operational flexibility: Unlike existing tooling fixtures with fixed installation structures that prevent valve body position adjustment during positioning, this fixture uses a micro electric cylinder to drive the positioning pulley, which allows the valve body to rotate and adjust its angle while maintaining centered positioning. This allows operators to flexibly change the workpiece position as needed, greatly improving operational convenience.

[0012] Enhanced scenario adaptability and expanded application scope: In response to the limitations of traditional fixtures in terms of weak applicability, it supports flexible switching between two modes: positioning clamping block fixation and positioning pulley positioning. It can meet the processing requirements of stable fixation and adapt to the assembly scenarios that require rotation and adjustment. It can adapt to the processing and assembly requirements of valve bodies with different shapes and different processes, effectively broadening the scope of application.

[0013] Enables on-demand switching of working states and improves work efficiency: Existing fixtures are difficult to adjust working states as needed, but this fixture, through the synergy of a hydraulic system and a micro electric cylinder, can accurately switch between fixed and rotating states while keeping the valve body position unchanged. It can adapt to different process requirements without repositioning, reduce repetitive operation time, and improve overall work efficiency. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0021] Example 1: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a tooling fixture for an irregularly shaped valve body, including a base 1. A mounting platform 101 is fixedly installed on the top of the base 1. Two sets of clamping frames 2 are fixedly installed on the top side of the mounting platform 101. The corners of the clamping frames 2 are all inclined structures. A hydraulic piston 202 is fixedly installed on the inner side of the inclined structure of the clamping frames 2. An L-shaped plate 3 is fixedly installed on the telescopic end of the hydraulic piston 202. Guide buckles 201 are fixedly installed on the corners of the adjacent surfaces of the two sets of clamping frames 2. The L-shaped plate 3 slides in the guide buckles 201. A miniature electric cylinder 4 is fixedly installed at the corner of the L-shaped plate 3. A pulley frame 401 is fixedly installed on the telescopic end of the miniature electric cylinder 4. Two sets of positioning pulleys 402 are rotatably installed in the pulley frame 401.

[0022] Among them, positioning clamps 301 are fixedly installed at the turning points of the L-shaped plate 3, and corrugated grooves are opened in the middle of the adjacent surfaces of the four sets of positioning clamps 301.

[0023] The L-shaped plate 3 has electrode rods 302 embedded at both ends, and the miniature electric cylinder 4 has wiring connected to the electrode rods 302.

[0024] The guide buckle 201 has brushes on both sides inside, and the brushes are attached to the electrode rod 302.

[0025] A hydraulic pump 5 is fixedly installed on the top of the base 1, and one end of the hydraulic pump 5 is connected to the hydraulic piston 202 by an oil circuit.

[0026] The base 1 has a hydraulic oil bladder 6 fixedly installed on its top, and the hydraulic oil bladder 6 is connected to one end of the hydraulic pump 5.

[0027] After placing the valve body in the middle of the clamp frame 2, start the hydraulic pump 5, extract the hydraulic oil from the hydraulic oil sac 6 and input it into each set of hydraulic pistons 202, causing the hydraulic pistons 202 to open and drive the L-shaped plate 3 to converge towards the middle, so that the positioning clamp 301 approaches and fits the workpiece, thus completing the fixation.

[0028] If the valve body needs to be rotated during assembly, the miniature electric cylinder 4 can be activated before the hydraulic piston 202 extends to push out the pulley frame 401 and the positioning pulley 402. At this time, the hydraulic piston 202 extends, and the positioning pulley 402 will be in contact with the valve body surface instead of the positioning clamp 301. This can achieve center positioning and keep the valve body in a rotating state, making it convenient to adjust the angle for subsequent assembly.

[0029] Example 2: During the process of fixing the valve body with the positioning clamp 301, the micro electric cylinder 4 can be extended to make the positioning pulley 402 contact the workpiece, and then the hydraulic pump 5 can be made to work in reverse to retract the hydraulic piston 202. This way, the fixing method can be switched from the positioning clamp 301 to the positioning pulley 402 while keeping the valve body position unchanged. When hydraulic pump 5 operates in reverse, all components can be reset.

[0030] The specific usage and function of this embodiment are as follows: In this utility model, when in use, according to Figure 1 In this manner, the valve body is placed in the middle of the clamp frame 2, and then the hydraulic pump 5 is started to draw out the hydraulic oil in the hydraulic oil sac 6 and input it into each set of hydraulic pistons 202. The hydraulic pistons 202 are opened, and the L-shaped plate 3 is brought together to the middle by the hydraulic pistons 202. Then the positioning clamp 301 also moves closer to the workpiece and fits the workpiece to achieve fixation. If the valve body needs to be rotated during assembly, the miniature electric cylinder 4 can be activated before the hydraulic piston 202 extends to push out the pulley frame 401 and the positioning pulley 402. At this time, if the hydraulic piston 202 extends, the positioning pulley 402 will contact the surface of the valve body instead of the positioning clamp 301, thus centering the valve body. The positioning pulley 402 provides a rotation effect, allowing the valve body to still rotate, which is convenient for adjusting the angle and facilitating subsequent assembly. The hydraulic pump 5 can be reset by working in reverse. In addition, during the process of fixing the positioning clamp 301, the miniature electric cylinder 4 can be extended, the positioning pulley 402 can be used to contact the workpiece, and then the hydraulic pump 5 can work in reverse to retract the hydraulic piston 202, thereby fixing the positioning clamp 301 and switching to positioning with the positioning pulley 402, and switching the installation state while maintaining the position of the valve body.
