Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically to a fixing device for processing oil pump valves. Background Technology

[0002] In industrial sectors such as oil extraction, oil pumps play a crucial role, undertaking key tasks such as ensuring normal equipment operation, precisely controlling fluid flow, and rationally regulating pressure. To meet the operational requirements of oil pumps, various valves are often required, among which gate valves are a commonly used type.

[0003] In the current technological environment, machining these types of valves typically requires the use of clamping and fixing devices to ensure the valve's stability during processing. Currently, there are various types of devices available for valve fixing, such as three-jaw chucks and clamping vises. However, these existing clamping devices have a significant limitation: once the valve is clamped and fixed, it is difficult to easily adjust its angle, such as by rotating or flipping it. If the valve angle needs to be adjusted, it must first be released from its clamping position, readjusted, and then re-fixed. This process is not only cumbersome but also significantly reduces processing efficiency and increases production and time costs.

[0004] Therefore, it is urgent to develop a fixing device specifically for the processing of oil pump valves, in order to solve the shortcomings of existing clamping devices in terms of angle adjustment and improve the convenience and efficiency of valve processing. Utility Model Content

[0005] The purpose of this utility model is to provide a machining and fixing device for oil pump valves to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve processing and fixing device for an oil pump, comprising a fixing plate, wherein a fixing mechanism for fixing the valve is provided between the fixing plates, the fixing mechanism comprising a mounting plate, a rotating platform, a three-jaw chuck, a first worm gear, a first worm, and a first servo motor, wherein the mounting plate is movably mounted between the fixing plates via a rotating shaft, a rotating platform is movably mounted at the middle of the upper part of the mounting plate via a rotating shaft, a three-jaw chuck is fixedly mounted at the upper part of the rotating platform, a first worm gear is fixedly mounted at one end of the rotating shaft where the mounting plate is located, so that when the first worm gear rotates, it can drive the mounting plate and all components at the upper part of the mounting plate to rotate together, a first worm is movably mounted on the surface of the right-side fixing plate via a bearing, and a first servo motor is fixedly mounted on the surface of the right-side fixing plate.

[0007] Preferably, the first worm and the first worm wheel mesh with each other, and the power output shaft of the first servo motor is connected to the first worm. The first servo motor can drive the first worm to rotate, which in turn drives the first worm wheel to rotate. This causes the mounting plate to rotate, thereby allowing the pitch angle of the valve fixed on the upper part of the mounting plate to be adjusted.

[0008] Preferably, a connecting plate is fixedly provided at the end of the mounting plate away from the first worm gear, so that the connecting plate can rotate together when the mounting plate rotates, and a drive mechanism for driving the rotating platform to rotate is provided on the outer surface of the connecting plate.

[0009] Preferably, the driving mechanism includes a second servo motor, a second worm gear, and a second worm. The second servo motor is fixedly mounted on the outer surface of the connecting plate, and the second worm gear is fixedly mounted on the lower end of the rotating shaft where the rotating platform is located, so that the rotation of the second worm gear can drive the rotating platform to rotate together. The second worm is movably mounted between the lower end of the mounting plate and the connecting plate through a bearing. The second worm gear and the second worm mesh with each other. The rotation of the second worm gear can drive the rotating table to rotate, thereby driving the valve on the upper end of the three-jaw chuck to adjust the rotation angle.

[0010] Preferably, the second servo motor and the second worm gear are connected by a synchronous pulley and a synchronous belt, and the second servo motor can drive the second worm gear to rotate.

[0011] Preferably, the surface of the fixing plate has a notch. Since a second worm gear is provided between the connecting plate and the mounting plate of this device, the connecting plate and the mounting plate will rotate together. Thus, the notch can prevent motion interference and allow the second worm gear to rotate together.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a first servo motor to drive a first worm gear to rotate, which in turn drives a first worm wheel to rotate, thus rotating a mounting plate. This allows for pitch angle adjustment of the valve fixed to the upper part of the mounting plate. The second worm gear drives a second worm wheel to rotate a rotary table, which in turn adjusts the rotation angle of the valve on the upper part of the three-jaw chuck. This allows for multi-angle adjustment of the valve after it has been machined and fixed, eliminating the need for readjustment and facilitating processing and use.

[0014] 2. The first worm gear, the first worm, the second worm gear, and the second worm can all be self-locking, that is, they can be automatically locked after being adjusted to the target angle. This eliminates the need for other complex angle fixing mechanisms and makes them more convenient to use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a valve processing and fixing device for an oil pump, including a fixing plate 1. A fixing mechanism for fixing the valve is provided between the fixing plates 1. The fixing mechanism includes a mounting plate 2, a rotating platform 3, a three-jaw chuck 4, a first worm gear 5, a first worm 6, and a first servo motor 7. The mounting plate 2 is movably arranged between the fixing plates 1 via a rotating shaft. The rotating platform 3 is movably arranged at the middle of the upper end of the mounting plate 2 via a rotating shaft. The three-jaw chuck 4 is fixedly arranged at the upper end of the rotating platform 3. The first worm gear 5 is fixedly arranged at one end of the rotating shaft where the mounting plate 2 is located, so that when the first worm gear 5 rotates, it can drive the mounting plate 2 and all the components at the upper end of the mounting plate 2 to rotate together. The first worm 6 is movably arranged on the surface of the right side of the fixing plate 1 via a bearing. The first servo motor 7 is fixedly arranged on the surface of the right side of the fixing plate 1.

[0021] The first worm 6 and the first worm wheel 5 mesh with each other. The power output shaft of the first servo motor 7 is connected to the first worm 6. The first servo motor 7 can drive the first worm 6 to rotate, which in turn drives the first worm wheel 5 to rotate. This can drive the mounting plate 2 to rotate, thereby allowing the valve fixed on the upper end of the mounting plate 2 to be tilted.

[0022] A connecting plate 8 is fixedly provided at the end of the mounting plate 2 away from the first worm gear 5, so that the connecting plate 8 can be driven to rotate together when the mounting plate 2 rotates. A drive mechanism for driving the rotating platform 3 to rotate is provided on the outer surface of the connecting plate 8.

[0023] The drive mechanism includes a second servo motor 9, a second worm gear 10, and a second worm 11. The second servo motor 9 is fixedly mounted on the outer surface of the connecting plate 8. The second worm gear 10 is fixedly mounted on the lower end of the rotating shaft where the rotating platform 3 is located, so that the rotating platform 3 can be driven to rotate together when the second worm gear 10 rotates. The second worm 11 is movably mounted between the lower end of the mounting plate 2 and the connecting plate 8 through a bearing. The second worm gear 10 and the second worm 11 mesh with each other. The rotation of the second worm gear 10 can drive the rotating table to rotate, thereby driving the valve on the upper end of the three-jaw chuck 4 to adjust the rotation angle.

[0024] The second servo motor 9 and the second worm gear 11 are connected by a synchronous pulley and a synchronous belt. The second servo motor 9 can drive the second worm gear 11 to rotate.

[0025] The surface of the fixed plate 1 has a notch 12. Since the second worm gear 11 is provided between the connecting plate 8 and the mounting plate 2 of this device, the connecting plate 8 and the mounting plate 2 will rotate together. Thus, the notch 12 can prevent motion interference and allow the second worm gear 11 to rotate together.

[0026] Working principle: When using this device, the valve to be processed is fixed by the three-jaw chuck 4, and then the valve can be processed. At this time, the first servo motor 7 drives the first worm gear 6 to rotate, which in turn drives the first worm wheel 5 to rotate, thus driving the mounting plate 2 to rotate. This allows the pitch angle of the valve fixed on the upper end of the mounting plate 2 to be adjusted. The second worm gear 11 drives the second worm wheel 10 to rotate, which drives the rotary table to rotate, thus allowing the rotation angle of the valve on the upper end of the three-jaw chuck 4 to be adjusted. In this way, the valve that needs to be processed and fixed can be adjusted at multiple angles without the need to readjust the fixed angle, which facilitates processing and use.

[0027] Meanwhile, the spiral angle of the worm in this device is smaller than the friction angle of the worm wheel and worm contact. As a result, the first worm wheel 5, the first worm 6, the second worm wheel 10, and the second worm 11 of this device can all be self-locking. That is, after adjusting to the target angle, they can be automatically locked. This eliminates the need for other complex angle fixing mechanisms and makes it more convenient to use.
