Description

Technical Field

[0001] The invention belongs to the technical field of valve processing, and in particular relates to a universal clamp for valve production. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems.

[0003] The valve body of the universal valve is a three-way structure. Connecting seats are provided at both ends and one side of the valve body. The connecting end of the connecting seat is a sealing surface. The valve body needs to undergo sealing surface grinding, sealing surface drilling and assembly processes during processing. Therefore, a sealing surface grinding station, a sealing surface drilling station and an assembly station need to be set up on the production line. Each station on the traditional production line is provided with a fixture for clamping and adjusting the position of the valve body, which not only makes the equipment cost high, but also wastes a lot of time each time the fixture is changed, resulting in low production efficiency. In addition, during the sealing surface grinding, sealing surface drilling and assembly processes, the sealing surface to be processed is usually adjusted to face upward, so that the debris generated by the sealing surface grinding and sealing surface drilling processes accumulates on the station or the valve body, increasing the difficulty of subsequent cleaning. In order to solve the above problems, a universal valve production fixture is provided.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0047] The support member 5 includes two linearly distributed guide rails 51, which are opened on the support platform 3. The two guide rails 51 are respectively located on both sides of the conical block 31. A sliding block 52 is slidably provided in the guide rail 51.

In the natural state of the spring 53 , the distance between the two insertion rods 58 is larger than the minimum aperture of the valve body 10 and smaller than the maximum outer diameter of the valve body 10 .

[0048] Two linearly distributed fifth electric telescopic rods 59 are also fixed on the support platform 3. The fifth electric telescopic rods 59 are parallel to the guide rail 51. A sixth electric telescopic rod 510 is vertically fixed to the output shaft of the fifth electric telescopic rod 59 close to the guide rail 51. A driving block 511 is fixed to the output shaft of the sixth electric telescopic rod 510.

[0049] The fixture also includes a collection assembly 6 for collecting debris, such as Figure 6 shown.

[0050] The collecting assembly 6 includes a connecting strip 61 fixed to one side of the first connecting plate 42, a fixed shaft 63 is fixed on the connecting strip 61, a limiting plate 62 is fixed on the fixed shaft 63, a connecting sleeve 64 is rotatably provided on the fixed shaft 63, a third connecting rod 65 is vertically fixed below the connecting sleeve 64, a U-shaped bracket 66 is fixed at the lower end of the third connecting rod 65, the collecting assembly 6 also includes a collecting box 67, both ends of the collecting box 67 are fixed with rotating shafts 68, the two rotating shafts 68 are respectively located on the side plates on both sides of the U-shaped bracket 66 and rotate, the rotating shaft 68 is perpendicular to the fixed shaft 63, the fixed shaft 63 is parallel to the output shaft of the first motor 14, and under the action of gravity, the box mouth of the collecting box 67 is always facing upwards.

[0051] When in use, the two first clamping plates 23 are controlled to be clamped on the frame of the production line. The production line includes a sealing surface grinding station, a sealing surface drilling station and an assembly station.

[0052] When it is necessary to process the connecting seats at both ends of the valve body 10, one end of the valve body 10 is put on the conical block 31, and the two second clamping plates 47 are controlled by the second electric telescopic rod 41, the third electric telescopic rod 43 and the second hydraulic rod 46 to clamp the connecting seat at one end of the valve body 10. When it is necessary to process the connecting seat on one side of the valve body 10, the second electric telescopic rod 41 and the fourth motor 45 are used to adjust the connecting seat on one side of the valve body 10 to face away from the support platform 3, and the connecting seat on one side of the valve body 10 is clamped by the two second clamping plates 47. After the clamping is completed, the corresponding connecting seat on the valve body 10 can be rubbed by extending one of the third electric telescopic rods 43 and shortening the other third electric telescopic rod 43, so that the control plate valve body 10 can rotate along the axis of the corresponding connecting seat.

[0053] When it is necessary to grind and drill the sealing surfaces at both ends of the valve body 10, a sealing surface away from the conical block 31 is the sealing surface to be processed. By starting the third motor 111, the support platform 3 is rotated vertically toward the side close to the collection component 6. At this time, the sealing surface to be processed on the valve body 10 is in a vertical state and is located directly above the collection box 67. The valve body 10 can then be ground or drilled. When drilling, the drilling position can be adjusted by controlling the valve body 10 to rotate along the axis of the conical block 31. The debris formed by grinding or drilling falls directly into the collection box 67, avoiding the accumulation of debris on the valve body 10 or the support platform 3, making it convenient to clean the valve body 10 or the support platform 3.

[0054] When assembling the valve, by adjusting the sealing surfaces of other parts to be installed on the valve body 10 to face upwards, and then placing the parts on the corresponding sealing surfaces, no additional clamps are needed to fix the parts, and the parts can be prevented from slipping and misaligning.

[0055] When the connecting seat on one side of the valve body 10 is adjusted to face the side away from the support platform 3, the valve body 10 is supported by the two slots 57, and the driving block 511 is adjusted to the side of the sliding block 52 close to the conical block 31 through the cooperation of the fifth electric telescopic rod 59 and the sixth electric telescopic rod 510. By starting the fifth electric telescopic rod 59, the two sliding blocks 52 are pushed away from each other, so that the two support plates 56 are respectively against the connecting seats at both ends of the valve body 10, thereby fixing the valve body 10.

[0056] When it is necessary to detect the aperture size on the valve body 10, the aperture to be detected on the valve body 10 is adjusted to face the support platform 3, and the fifth electric telescopic rod 59 and the sixth electric telescopic rod 510 are started to cooperate to adjust the drive block 511 to the side of the sliding block 52 away from the conical block 31, and the two sliding blocks 52 are controlled to approach each other by contracting the fifth electric telescopic rod 59, and the insertion rod 58 is driven to approach each other at the same time, and the insertion rod 58 is controlled to be inserted into the corresponding aperture by extending the fourth electric telescopic rod 54, and the driving block 511 is controlled to disengage from the sliding block 52 by extending the fifth electric telescopic rod 59. Under the action of the spring 53, the two insertion rods 58 are against the inner walls on both sides of the corresponding aperture, and the distance is detected by the distance sensor to calculate the diameter of the aperture.

[0057] When it is necessary to detect the outer wall size of the valve body 10, the position to be detected on the valve body 10 is adjusted to face the support platform 3, and the fifth electric telescopic rod 59 and the sixth electric telescopic rod 510 are started to cooperate to adjust the driving block 511 to the side of the sliding block 52 close to the conical block 31, and the two sliding blocks 52 are controlled to move away from each other by extending the fifth electric telescopic rod 59, and the insertion rod 58 is driven away from each other at the same time, and the two insertion rods 58 are controlled to move to the two sides of the position to be detected by extending the fourth electric telescopic rod 54, respectively, and the driving block 511 is controlled to disengage from the sliding block 52 by contracting the fifth electric telescopic rod 59. Under the action of the spring 53, the two insertion rods 58 are against the two sides of the position to be detected, and the distance is detected by the distance sensor to calculate the diameter of the position to be detected.

[0058] When the position of the entire clamp needs to be adjusted, if one end of the valve body 10 is currently sleeved on the conical block 31, the fifth electric telescopic rod 59 and the sixth electric telescopic rod 510 cooperate to control one side of the T-shaped connecting rod 55 to press the connecting seat of the valve body 10 close to the support platform 3 to fix the valve body 10, and then control the second clamping plate 47 to release the valve body 10. If the two support plates 56 are respectively against the connecting seats at both ends of the valve body 10 to fix the valve body 10, the second clamping plate 47 can be directly controlled to release the valve body 10.

[0059] Then, by starting the first motor 14, the second motor 16, the fifth motor 19, the third motor 111, the second electric telescopic rod 41 and the third electric telescopic rod 43, the two second clamping plates 47 are controlled to be adjusted to the two sides of the position to be fixed respectively, and the second clamping plate 47 is controlled to be clamped at the position to be fixed by extending the second hydraulic rod 46, and then the first hydraulic rod 22 and the first electric telescopic rod 12 are used to control it to be removed from the clamped position, and the two first clamping plates 23 are controlled to move to the next position to be fixed respectively by the third motor 111 and the first electric telescopic rod 12, and then the second clamping plate 47 is controlled to be removed from the clamped position, so as to realize the movement of the fixture on the production line until the two first clamping plates 23 are clamped at the workstation to be processed. By setting a self-movable fixture, not only can the use of the fixture be reduced and the equipment cost be saved, but also there is no need to re-clamp the valve body 10 at each workstation, thereby improving the processing efficiency.
