Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing tooling, in particular to a horizontal processing tooling for butterfly valves. Background Art

[0002] As a cutting device widely used in industrial pipeline systems, the processing quality of butterfly valves directly affects the operating stability and reliability of the entire pipeline system. In the processing of butterfly valves, tooling and fixtures play a vital role, and their performance is directly related to processing efficiency and product quality.

[0003] Traditional butterfly valve processing tooling has many disadvantages. On the one hand, the clamping and positioning function is single, and most of them can only clamp the butterfly valve from one or two directions, which makes it difficult to ensure the stability of the butterfly valve during processing, causing the butterfly valve to easily shift or shake during processing, seriously affecting the processing accuracy, resulting in poor sealing performance of the butterfly valve and reduced product quality. On the other hand, traditional tooling has poor applicability and can usually only process butterfly valves of specific sizes and specifications, which cannot meet the diversified production needs of enterprises. When an enterprise needs to process butterfly valves of different sizes, it often needs to replace different tooling, which not only increases the production cost of the enterprise, but also consumes a lot of time and reduces production efficiency.

[0004] In addition, traditional tooling also has great limitations in adjusting the processing angle. Usually, it is not convenient to adjust the angle of the butterfly valve after clamping (such as a butterfly valve horizontal processing tooling proposed in the authorization announcement number CN221936011U), which makes it inconvenient to adjust the butterfly valve according to the needs of butterfly valve processing during processing, which will affect the efficiency of butterfly valve processing to a certain extent and restrict the improvement of production efficiency.

[0005] In view of this, the development of a horizontal processing tool for butterfly valves that can stably clamp butterfly valves of different sizes, conveniently adjust the processing angle, and is simple and convenient to operate is of extremely important practical significance for improving the processing efficiency and quality of butterfly valves and reducing the production costs of enterprises.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0029] Refer to Figures 1 - 5 , a horizontal processing tooling for a butterfly valve, including a support frame 1, a strip board 2, two support plates 21, four clamping plates 4 and a bracket 3. A servo motor 201 is fixedly installed on the support frame 1, and the strip board 2 is fixedly installed on the output shaft of the servo motor 201. Installation frames are fixedly installed at both ends of the bottom side of the strip board 2, and support wheels 202 are rotatably installed on both installation frames. Both support wheels 202 are rollingly installed on the support frame 1, which can provide stable support for the strip board 2 and at the same time does not affect the servo motor 201 to control the rotation operation of the strip board 2;

[0030] Both support plates 21 are fixedly installed on the top side of the strip board 2 and are arranged in parallel. All four clamping plates 4 are arranged between the two support plates 21. Two installation openings are formed in the two support plates 21, and gears 42 are rotatably installed in all four installation openings. The four gears 42 are respectively meshed with the corresponding first toothed plates 41. The first toothed plates 41 are slidably installed in all four installation openings, and the four first toothed plates 41 are respectively fixedly connected to the corresponding clamping plates 4. Two second toothed plates 43 are slidably installed on the strip board 2, and the two second toothed plates 43 are respectively meshed with the two gears 42 on the corresponding side, which can provide stable support for the four clamping plates 4 and can realize synchronous control of the four clamping plates 4 to clamp or release the clamping positioning operation when controlling the two second toothed plates 43 to rise and fall.

[0031] The bottom ends of the two second toothed plates 43 both extend below the strip board 2 and are fixedly installed with the same connecting ring 5. An electric cylinder 52 is fixedly installed on the support frame 1, and a support bar 51 is slidably installed on the support frame 1. An annular groove is formed in the inner side wall of the connecting ring 5. Both ends of the support bar 51 extend into the annular groove and are in sliding contact with the inner side wall of the annular groove. The working end of the electric cylinder 52 is fixedly connected to the top side of the support bar 51, which can control the two second toothed plates 43 to rise or fall synchronously as needed;

[0032] The bracket 3 is arranged above the strip plate 2. A square rod 32 is fixedly installed on the top side of the strip plate 2. A hollow plate 31 is slidably sleeved on the square rod 32. The bracket 3 is fixedly installed on the top side of the hollow plate 31. A fixed block 33 is fixedly installed on one side of the hollow plate 31. A lead screw 34 is threadedly installed on the fixed block 33. The bottom end of the lead screw 34 is rotatably installed on the strip plate 2. The top end of the lead screw 34 is fixedly sleeved with an adjusting wheel, which can control the lifting of the hollow plate 31 as needed to adjust the height of the bracket 3.

[0033] In this embodiment, in order to provide stable guidance for the support bar 51, a guide rod 53 is fixedly installed on the support bar 51, and the guide rod 53 is slidably connected to the support frame 1.

[0034] In this embodiment, in order to facilitate the stability of the operator when placing the butterfly valve to be processed on the bracket 3, while ensuring both the contact area between the clamping plate 4 and the butterfly valve to be clamped and avoiding the mutual sliding between the butterfly valve and the clamping plate 4 during the clamping and processing operations, which may affect the processing accuracy, the top side of the bracket 3 is arranged in an arc shape, and the mutually approaching sides of the four clamping plates 4 are all arranged in an arc shape, and a protective pad is fixedly pasted on the mutually approaching sides of the four clamping plates 4.

[0035] In this embodiment, in order to enable the four clamping plates 4 to clamp and position the butterfly valve from different angles, so as to ensure the stability after clamping and positioning the butterfly valve, the included angle between the two first toothed plates 41 on the same support plate 21 is 30-90°.

[0036] For the circuits, electronic components and module mechanisms involved, etc., the existing technologies are adopted, and those skilled in the art can fully implement them without further elaboration. The content protected by this application does not involve improvements to software, circuits and methods either.

[0037] Working principle:

[0038] Height adjustment: Before processing, according to the size of the butterfly valve, the operator rotates the adjusting wheel to drive the lead screw 34 to rotate. Since the fixed block 33 is fixed to the hollow plate 31 and the lead screw 34 is in threaded cooperation with the fixed block 33, the hollow plate 31 will slide up and down along the square rod 32, thereby adjusting the height of the bracket 3 to facilitate the subsequent placement of the butterfly valve.

[0039] Butterfly valve placement: Place the butterfly valve to be processed on the bracket 3. The arc surface on the top side of the bracket 3 can increase the contact area with the butterfly valve, improve the stability during placement, and facilitate subsequent clamping.

[0040] Clamping operation: Start the electric cylinder 52, and its working end pushes the support bar 51 downward. The support bar 51 drives the connecting ring 5 to descend. Since the connecting ring 5 is fixedly connected to the two second toothed plates 43, the second toothed plates 43 descend accordingly, and the gear 42 meshing with the second toothed plates 43 rotates. Since the gear 42 meshes with the first toothed plate 41, it can drive the first toothed plate 41 to slide within the installation opening, thereby causing the four clamping plates 4 to approach each other and clamp the butterfly valve. Additionally, due to the arc surfaces on the sides where the four clamping plates 4 approach each other and the setting of the protective pads, it can not only increase the contact area with the butterfly valve but also prevent the butterfly valve from sliding during clamping and processing, thus ensuring the machining accuracy. Moreover, the two first toothed plates 41 on the same support plate 21 form an angle of 30 - 90°, enabling the clamping plates 4 to clamp the butterfly valve from different angles and improving the clamping stability.

[0041] Processing angle adjustment: After clamping is completed, start the servo motor 201. Its output shaft drives the strip-shaped plate 2 to rotate. The support wheels 202 on the bottom side of the strip-shaped plate 2 roll on the support frame 1, providing stable support for the strip-shaped plate 2 while not hindering its rotation, thereby adjusting the processing angle of the butterfly valve to meet different processing requirements.

[0042] Loosen the tooling: After processing is completed, the working end of the electric cylinder 52 retracts, driving the support bar 51 to rise, causing the connecting ring 5 and the second toothed plates 43 to rise, thereby enabling the four clamping plates 4 to move away from each other and loosen the butterfly valve, facilitating the removal of the processed butterfly valve.

[0043] The above has introduced in detail a horizontal processing tooling for a butterfly valve provided by the present utility model. Specific embodiments are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
