Description

Technical Field

[0001] This utility model relates to the field of roller pressing fixture technology, specifically a roller pressing fixture for valve plate rubber and plastic sealing rings. Background Technology

[0002] Butterfly valves and other valves are widely used for shut-off and throttling. The quality of their sealing pair structure determines the sealing performance and production cost of the product. Most butterfly valves used for shut-off employ a combination of metal and non-metal seals. The metal seal compresses the non-metal seal to form an interference fit, thereby generating a certain sealing pressure between the sealing surfaces to achieve a sealing effect. This places high demands on the processing quality of the rubber and plastic sealing rings. Traditional press-fitting equipment mostly lacks adjustment functions and can only press-fit one type of valve body and sealing ring. When different types of valve bodies and sealing rings need to be press-fitted, corresponding press-fitting equipment is required, which not only wastes resources but also fails to meet the diverse usage needs of customers.

[0003] Existing valve plate rubber and plastic sealing ring rolling fixtures are not convenient for adjusting the included angle between rollers when rolling the sealing rings, are not suitable for rolling sealing rings of various thicknesses, and have a limited range of applications. Furthermore, existing valve plate rubber and plastic sealing ring rolling fixtures are not convenient for adjusting the appropriate height according to the thickness of the sealing ring. The present invention provides a valve plate rubber and plastic sealing ring rolling fixture that solves the above problems. Utility Model Content

The outer side of the lifting plate 303... The height adjustment mechanism 2 includes an adjustment box 201, a servo motor 202, a threaded rod 203, a threaded ring block 204, a rectangular slider 205, a vertical plate 206, and a strip plate 207. The output end of the servo motor 202 is equipped with a threaded rod 203 that is connected to the threaded ring block 204. Rectangular sliders 205 for guidance are installed on both sides of the threaded ring block 204, and a vertical plate 206 is installed on the top of the threaded ring block 204.

[0017] Specifically, the cooperation between the electric push rod 302 and the lifting plate 303 facilitates the movement of the positioning slider 305, thereby facilitating the adjustment of the included angle between the rollers 309.

[0018] Please see Figures 1 to 5 The electric push rod 302 is installed behind the L-shaped plate 301, the lifting plate 303 is installed at the movable end of the electric push rod 302, and the round rod 306 is installed on the inner wall of the L-shaped plate 301.

[0019] Specifically, the cooperation between the guide slider 304 and the guide groove serves to guide the movement of the lifting plate 303, improve the stability of the lifting movement of the positioning slider 305, and facilitate the movement of the adjusting plate 308, thereby facilitating the adjustment of the included angle between the rollers 309.

[0020] Please see Figures 1 to 5 The L-shaped plate 301 has a guide groove inside for guiding the guide slider 304. The end of the guide slider 304 is located inside the guide groove. The front of the adjusting plate 308 has a positioning groove for guiding the positioning slider 305. The end of the positioning slider 305 is located inside the positioning groove.

[0021] Specifically, during adjustment, the two mating plates 307 move synchronously, which facilitates the synchronous movement and adjustment of multiple rollers 309.

[0022] Please see Figures 1 to 5 The adjusting plate 308 is installed on one side of the mating plate 307. There are two mating plates 307, which are symmetrical about the middle position of the L-shaped plate 301. There are several rollers 309.

[0023] Specifically, the cooperation between the rectangular slider 205 and the rectangular groove guides the movement of the threaded ring block 204, the L-shaped plate 301 and the roller 309, thereby improving the stability of the movement of the roller 309.

[0024] Please see Figure 4 The strip plate 207 is installed on the inner wall of the regulating box 201, and the servo motor 202 is installed on the inner bottom wall of the regulating box 201. A rectangular groove for guiding the movement of the rectangular slider 205 is provided on one side of the strip plate 207, and the end of the rectangular slider 205 is located inside the rectangular groove.

[0025] Specifically, it facilitates the adjustment of the roller 309 to a suitable operating height, thereby expanding its applicability.

[0027] In use, the valve plate is clamped on a lathe and aligned, with a concentricity of less than 0.1mm. The rolled sealing ring is placed on the valve plate, and the sealing ring and valve plate abut against the roller 309. The lathe drives the valve body to rotate at a suitable speed, which realizes the rolling of the valve body and the sealing ring and makes them tightly bonded. When the appropriate included angle between the multiple rollers 309 is adjusted according to the thickness of the sealing ring, the movable end of the electric push rod 302 extends or retracts, causing the lifting plate 303 to drive the guide slider 304 and the positioning slider 305 to move. The guide slider 304 moves inside the guide groove, playing a guiding role. The movement of the positioning slider 305 drives the adjusting plate 308 to move, so that the adjusting plate 308 and the mating... Plate 307 moves in an arc trajectory around the center of the circular rod 306, facilitating the adjustment of the included angle between the mating plates 307. The movement of the mating plates 307 drives the rollers 309 to move, thereby facilitating the adjustment of the included angle between multiple rollers 309 and improving the applicability. When adjusting to a suitable operating height, the servo motor 202 drives the threaded rod 203 to rotate. The threaded rod 203 is connected to the threaded ring block 204. The rectangular slider 205 moves guided inside the rectangular groove opened on the strip plate 207, causing the threaded ring block 204 to drive the rectangular slider 205, the vertical plate 206, the L-shaped plate 301, and the rollers 309 to move up or down, facilitating the adjustment of a suitable operating height and improving practicality.
