Description

Technical Field

[0001] The utility model relates to the field of three-way valve processing, in particular to a fixing fixture for three-way valve processing. Background Art

[0002] A three-way valve is a valve device with three ports, usually designed as one inlet and two outlets (one inlet and two outlets, with a layout such as left inlet, right and bottom outlet), or two inlets and one outlet, used to control the flow direction and flow rate of fluids (such as air, water, steam, various corrosive media, oil, etc.) in a pipeline system.

[0003] During the processing of the existing three-way valve, it is necessary to place it in the lower clamp. After the three-way valve is placed, the cylinder is started to drive the upper clamp to move. The upper clamp moves to contact the three-way valve to clamp it. The three-way valve can be fixed between the lower clamp and the upper clamp. During the fixing process of the three-way valve, due to the special shape of the three-way valve, it may cause the clamping force to be difficult to distribute evenly. Some areas may be clamped too tightly and deformed, while other areas may be insufficiently clamped, resulting in vibration or movement during the processing of the three-way valve, which is easy to affect the surface quality and processing efficiency.

[0004] In view of the above problems, it is necessary to design a fixing fixture for three-way valve processing to protect the three-way valve. Utility Model Content

[0005] In order to overcome the disadvantages that the clamping force may be difficult to distribute evenly due to the special shape of the three-way valve, and some areas may be deformed by clamping too tightly, the utility model provides a fixing fixture for processing the three-way valve.

[0006] The technical solution of the utility model is: a fixing fixture for processing a three-way valve, comprising a mounting seat, a lower fixture, a cylinder, an upper fixture and a three-way valve body, the mounting seat is connected with the lower fixture, the three-way valve body is placed on the lower fixture, a cylinder is installed on the left side of the mounting seat, the telescopic end of the cylinder is connected with the upper fixture, the upper fixture is located above the three-way valve body, and also includes a rubber protective pad, the lower fixture is connected to the rubber protective pad, and the upper fixture is also connected to the rubber protective pad.

[0007] Furthermore, it also includes a slide rail, the mounting seat is symmetrically connected to the slide rail, and the upper clamp is slidably matched with the slide rail.

[0008] Furthermore, it also includes a fixing block and a mounting flange. The fixing block is connected to the left side of the mounting seat, and the mounting flange is connected to the left side of the fixing block. A plurality of mounting holes are opened on the mounting flange.

[0009] Furthermore, it also includes a mounting screw, and the mounting seat is threadedly connected with the mounting screw.

[0010] Furthermore, the mounting flange is made of stainless steel.

[0011] Furthermore, the number of the mounting screws is not less than four.

[0012] The beneficial effects of the utility model are as follows: the upper clamp is driven to move by the cylinder and the cylinder telescopic rod, and the upper clamp moves to contact and fix the three-way valve placed on the lower clamp, and during the fixing process, the rubber protective pads in the upper clamp and the lower clamp fit with the three-way valve. The rubber protective pads can prevent the metal clamp from directly contacting the valve body or valve core surface of the three-way valve during the processing of the three-way valve, thereby preventing scratches, indentations or damage during the processing or fixing process.

[0017] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Embodiment: A three-way valve processing fixture, such as Figure 1-Figure 3As shown, it includes a mounting seat 1, a lower clamp 2, a cylinder 3, an upper clamp 4, a rubber protective pad 5, a slide rail 6, a mounting screw 7, a fixing block 8, a mounting flange 9 and a three-way valve body 11. The mounting seat 1 is connected with the lower clamp 2, and the three-way valve body 11 can be placed on the lower clamp 2. The three-way valve body 11 is placed on the lower clamp 2. The cylinder 3 is installed on the left side of the mounting seat 1. The upper clamp 4 is connected to the telescopic end of the cylinder 3. The upper clamp 4 is located above the three-way valve body 11. The upper clamp 4 fits with the lower clamp 2 to fix the three-way valve body 11. The lower clamp 2 is internally connected with a rubber protective pad 5, and the upper clamp 4 is also internally connected with a rubber protective pad. The protective pad 5, the rubber protective pad 5 can prevent the metal clamp from directly contacting the valve body or valve core surface of the three-way valve, and prevent scratches, indentations or damage during its processing or fixing process. The mounting seat 1 is symmetrically connected with a slide rail 6, and the upper clamp 4 slides with the slide rail 6. The mounting seat 1 is threadedly connected with a mounting screw 7. The number of the mounting screws 7 is not less than four. The mounting screws 7 can fix the mounting seat 1 on the workbench. The left side of the mounting seat 1 is connected with a fixing block 8, and the left side of the fixing block 8 is connected with a mounting flange 9. The mounting flange 9 is made of stainless steel, which can resist corrosion, and a plurality of mounting holes 10 are provided on the mounting flange 9.

[0019] When the device is needed, during the processing of the three-way valve, when the three-way valve needs to be fixed, the staff will place the device on the workbench. After the device is placed, the staff will put the mounting screw 7 on the mounting seat 1, and then rotate the mounting screw 7 along the mounting seat 1. When the mounting screw 7 is rotated to a suitable position, the mounting screw 7 is loosened, and the above-mentioned operation of rotating the mounting screw 7 is repeated, so that other mounting screws 7 are also installed on the mounting seat 1, which is convenient for fixing the mounting seat 1 on the workbench. During the installation of the device, the mounting flange 9 on the device can also be brought into contact with the grinder, and then installed on the grinder. Both installation methods can ensure the stability of the device. After the device is fixed, it is started The cylinder 3 and the telescopic rod of the cylinder 3 drive the upper clamp 4 to move upward along the slide rail 6. When the upper clamp 4 moves to an appropriate height, the three-way valve is placed on the lower clamp 2, so that the three-way valve contacts and fits with the rubber protective pad 5. When the three-way valve is placed, the telescopic rod of the cylinder 3 drives the upper clamp 4 to move downward along the slide rail 6. The upper clamp 4 moves to contact and fix the three-way valve, so that the three-way valve contacts and fits with the rubber protective pad 5 in the upper clamp 4. The rubber protective pad 5 can prevent the metal clamp from directly contacting the valve body or valve core surface of the three-way valve, thereby preventing scratches, indentations or damage during its processing or fixing process. After the three-way valve is fixed, the cylinder 3 is closed to facilitate the processing of the fixed three-way valve.
