Technical Field

Although the existing positioning device for valve processing can realize the automation of valve processing and complete the complete painting operation of the valve, since the valve production process requires clamping processing, the existing device cannot automatically adjust the clamping force of the valve and cannot control it according to the clamping strength, resulting in excessive clamping force causing wear on the valve, and excessive clamping force will cause the valve to shake during the processing due to unstable clamping, which is very likely to have an adverse effect on the subsequent processing flow.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following will describe in detail the specific implementation of the present disclosure with reference to the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

Specifically, with reference to Figure 1 the drawing direction shown in the figure, the side pointed by the Z arrow is the upper and top, and the opposite side is the lower and bottom. In addition, the Z direction refers to the height direction of the valve, and the X direction refers to the width direction of the valve; the X and Y directions refer to the horizontal direction, and the Z direction refers to the vertical direction. The terms such as "first" and "second" used in the present disclosure are used to distinguish one element from another and do not have sequentiality and importance. In addition, when the following description refers to the drawings, the same reference numerals in different drawings represent the same or similar elements.

[0036] With reference to Figures 1 - 5 , the present disclosure provides a processing and positioning device for a valve. The processing and positioning device may include a base 1 for supporting the valve. In the embodiment provided in the present disclosure, the valve may be a high-temperature and high-pressure resistant valve. The processing and positioning device may further include a resisting block 42, two clamping plates 2, a pressure sensor 5, and a driving assembly 3. The resisting block 42 may be used to press against the top of the valve along the Z direction, and the resisting block 42 may be configured to be able to reciprocate relative to the base 1 along the Z direction and the X direction perpendicular to the Z direction so as to be adjustable according to the height of the valve along the Z direction and the position along the X direction, thereby positioning the valve at a suitable position on the base 1. It should be noted that in the present disclosure, the pressing pressure of the resisting block 42 only needs to ensure that the valve remains in its current position during the processing. The resisting block 42 may be made of a flexible material, for example, it may be made of rubber material, so as to avoid excessive hardness of the resisting block 42 from wearing the valve. The two clamping plates 2 may be slidably arranged relative to each other along the X direction on one side of the base 1 for supporting the valve. The relative displacement of the two clamping plates 2 can be adjusted to adjust the clamping force on the valve, and the clamping of valves with different widths can be achieved, thereby improving the versatility of the processing and positioning device. The pressure sensor 5 may be arranged on the side of the clamping plate 2 for clamping the valve. The pressure sensor 5 may be used to detect the pressure between the two clamping plates 2 and send out a pressure signal. The driving assembly 3 may be configured to be able to drive a relative displacement capable of changing the pressure between the two clamping plates 2 according to the pressure signal, thereby adjusting the clamping force of the two clamping plates 2 to an appropriate range.

[0037] Through the above technical solution, the anti-blocking block 42 limits the valve to a suitable position on the base 1 according to the valve height, and the driving assembly 3 adjusts the clamping force of the clamping plate 2 on the valve according to the pressure signal detected by the pressure sensor 5, so as to adjust the clamping force to a suitable range. While being able to automatically monitor and adjust the clamping force of the clamping plate 2, it effectively improves the clamping suitability and stability of the processing positioning device for the valve, ensuring the smooth progress of the valve processing work.

[0038] Referring to Figure 1 and Figure 2 , the driving assembly 3 may include two driving screws 31 and a driving motor 32. The two driving screws 31 may be threadedly connected to the two clamping plates 2 movably along the X direction in a one-to-one correspondence, and are arranged at intervals along the Y direction perpendicular to the X direction and the Z direction respectively, so as to drive the movement of the clamping plate 2 along the X direction by rotating around its own axis. The driving motor 32 may be signal-connected to the pressure sensor 5 for receiving the pressure signal. The driving motor 32 may drive the two driving screws 31 to rotate around their own axes according to the direction of the pressure signal. In the present disclosure, the number of driving motors 32 may be two, and the two driving motors 32 respectively correspond to one driving screw 31. As Figure 2 shown, when the pressure sensor 5 detects that the clamping pressure of the clamping plate 2 is less than the preset pressure, after receiving the pressure signal, the driving motor 32 may drive the first driving screw 311 to rotate in the S direction, and the driving motor 32 drives the second driving screw 312 to rotate in the direction away from S, so that the two clamping plates 2 move towards each other to increase the clamping force between the two clamping plates 2. When the pressure sensor 5 detects that the clamping pressure of the clamping plate 2 reaches the preset pressure, the driving motor 32 stops rotating to cancel the driving force on the clamping plate 2. When the pressure sensor 5 detects that the clamping pressure of the clamping plate 2 is greater than the preset pressure, the rotation directions of the first driving screw 311 and the second driving screw 312 are opposite to the rotation directions when the clamping pressure of the clamping plate 2 is less than the preset pressure, and the specific adjustment process is the same, which will not be elaborated here. Through this adjustment method, no manual participation is required, effectively ensuring the precise adjustment of the clamping force of the clamping plate 2 and effectively improving the movement efficiency of the clamping plate 2.

[0039] Referring to Figure 1 , Figure 2 and Figure 4, the driving assembly 3 further includes a driving slider 33 connected between the driving screw 31 and the clamping plate 2 along the Z direction. Among them, the driving slider 33 is fixedly connected to the clamping plate 2, and the driving slider 33 is threadedly connected to the driving screw 31 movably along the X direction, so as to output the driving force of the rotation of the driving screw 31 as the driving force capable of driving the clamping plate 2 to move along the X direction. Using the driving slider 33 as the connecting component between the driving screw 31 and the clamping plate 2 makes it easier and more stable to transmit the driving force of the driving screw 31, and makes the clamping plate 2 only used for clamping the valve without participating in other work, improving the service life of the clamping plate 2. Refer to Figure 2 , in the embodiment provided by the present disclosure, a first limiting slider 34 may be further provided between the driving screw 31 and the clamping plate 2. The first limiting slider 34 is spaced from the driving slider 33 along the Y direction. One end of the first limiting slider 34 is fixedly connected to the clamping plate 2, and the other end of the first limiting slider 34 is sleeved on the driving screw 31 and slidably connected to the driving screw 31, thereby improving the stability during the movement of the clamping plate 2.

[0040] Refer to Figure 1 , the base 1 can be configured as a hollow shell, and the driving screw 31 and the driving motor 32 can be accommodated in the base 1. While ensuring the stability of placing the valve on the base 1, it effectively improves the utilization rate of the internal space of the base 1, and at the same time makes the layout of components more compact, reducing the space occupied by the processing positioning device. On the side of the base 1 for carrying the valve, a first chute 11 extending along the X direction and symmetrically arranged along the Y direction can be provided, and the two driving sliders 33 are slidably connected to the two first chutes 11 in a one-to-one correspondence, thereby realizing precise control of the clamping position of the clamping plate 2. At the same time, during the movement of the driving slider 33, it will not interfere with other components, effectively improving the flexibility of using the processing positioning device while realizing the adjustable position of the clamping plate 2.

[0041] Refer to Figure 1 , the processing positioning device may further include a limiting assembly 4, and the limiting assembly 4 may include a support frame 41 and a resisting block 42. The support frame 41 can be configured as a U-shaped structure with an opening facing the base 1. The two first side beams 411 on the opening side of the U-shaped structure are spaced along the X direction and vertically abut against the surface of the base 1 for supporting the valve along the Z direction. The resisting block 42 can be arranged on the second side beam 412 on the closed side of the U-shaped structure and is slidably matched with the second side beam 412 along the X direction and the Z direction. By providing the support frame 41, a stable installation position can be provided for the resisting block 42. At the same time, the resisting block 42 is slidably matched with the second side beam 412 along the X direction and the Z direction, which can realize the fine adjustment and movement of the position of the resisting block 42, improving the flexibility and applicability of the resisting block 42, so that the processing positioning device can position and process valves of different sizes and ensure the stability during the valve processing.

[0042] Reference Figure 1 and Figure 3 The limiting assembly 4 may further include a second slide groove 413, a second limiting slider 43 and a limiting screw 44. The second slide groove 413 may be provided on the second side beam 412, and the length direction of the second slide groove 413 may extend along the X direction. By forming the second slide groove 413 on the body of the second side beam 412, the overall effect of the device is improved, the use of components can be reduced, and the stability of the second slide groove 413 during use is ensured. The second limiting slider 43 may be slidably connected to the second slide groove 413 along the X direction. In the embodiment provided by the present disclosure, Figure 1 and Figure 5 As shown, two U-shaped grooves 413a that are concave inward along the Y direction can be formed on the second slide groove 413, and the opening directions of the two U-shaped grooves 413a are arranged oppositely, and the second limit slider 43 can be embedded in the U-shaped groove 413a. In this way, while the second limit slider 43 can move along the second slide groove 413, the U-shaped groove 413a can also provide vertical support and horizontal limitation for the second limit slider 43, so as to effectively ensure the stability of the second limit slider 43 during the sliding process of the second slide groove 413. Figure 1 and Figure 3 , the limit screw 44 can extend along the Z direction, one end of the limit screw 44 close to the base 1 can be fixedly connected to the resistance block 42, and the other end of the limit screw 44 can be movably threadedly connected to the second limit slider 43 along the Z direction. In the embodiment provided by the present disclosure, when the resistance block 42 has a need to move along the X direction, the limit screw 44 can be driven by moving the second limit slider 43 to drive the resistance block 42 to move. When the resistance block 42 has a need to move along the Z direction, for example, when it has a need to move upward, the limit screw 44 can move along the S' direction (clockwise), thereby driving the resistance block 42 to move upward. When it has a need to move downward, the limit screw 44 can move away from the S' direction (counterclockwise), thereby driving the resistance block 42 to move downward. This method of adjusting the height of the resistance block 42 in the Z direction is not only simple but also easy to implement.

[0043] Reference Figure 1, the second side beam 412 is configured as a U-shaped beam. Along the Z direction, the two ends where the opening of the U-shaped beam is located are respectively coaxially and telescopically arranged with the two first side beams 411. In order to make the height of the support frame 41 formed by the second side beam 412 and the two first side beams 411 adjustable in the Z direction, in the embodiment provided by the present disclosure, the first side beam 411 can be configured as a tubular structure with a hollow interior. The opening of the second side beam 412 can be arranged downward, and the two ends where the opening of the U-shaped beam is located can be respectively inserted coaxially into the two first side beams 411, so that the height of the support frame 41 in the Z direction is telescopic. In this way, when the distance between the bottom surface of the resisting block 42 and the top surface of the valve varies greatly, the height of the support frame 41 in the Z direction can be adjusted first to roughly adjust the height of the resisting block 42, and then the height of the resisting block 42 can be finely adjusted through the limiting screw 44 and the second limiting slider 43, so that the height of the resisting block 42 is the same as the height of the top surface of the valve, thereby effectively improving the efficiency of the resisting block 42 and the versatility of the machining positioning device.

[0044] Further, referring to Figure 1 , in order to ensure the telescopic height of the second side beam 412 and the first side beam 411, so that the height of the support frame 41 in the Z direction remains unchanged at the current position, in the embodiment provided by the present disclosure, the limiting assembly 4 can further include a limiting pin 414. When the first side beam 411 and the second side beam 412 are adjusted to a suitable position, the limiting pin 414 can pass through the first side beam 411 and then abut against the second side beam 412, thereby limiting the relative displacement between the first side beam 411 and the second side beam 412, improving the stability of the support of the support frame 41, and ensuring the limiting effect of the resisting block 42 on the position of the valve.

[0045] Referring to Figure 1 and Figure 2 , the machining positioning device can further include two anti-slip pads 6, and the two anti-slip pads 6 can be respectively detachably arranged on the opposite surfaces of the two clamping plates 2. That is, an anti-slip pad 6 can be provided on the side surface of each clamping plate 2 for clamping the valve. By providing the anti-slip pad 6, the friction coefficient between the clamping plate 2 and the valve can be increased, so as to prevent the valve from detaching from the clamping plate 2 during the machining process, thereby improving the stability of the valve machining process. In the present disclosure, the anti-slip pad 6 can be made of a flexible material, for example, it can be made of a rubber material. In this way, it can play an anti-slip role while also playing a buffering role, and can also prevent the clamping plate 2 from directly contacting the valve, reducing the wear of the clamping plate 2 on the valve, thereby effectively improving the service life of the valve.

[0046] Referring to Figure 2, the pressure sensor 5 is partially embedded in the anti-slip pad 6. In the present disclosure, the sensing part of the pressure sensor 5 can be externally exposed and not protrude from the anti-slip pad 6. In this way, while avoiding interference of the anti-slip pad 6 with the detection effect of the pressure sensor, it can also prevent the pressure sensor 5 from protruding from the anti-slip pad 6 due to excessive external exposure, effectively reducing the risk of interference between the pressure sensor 5 and the valve or other external devices, and greatly improving the service life of the pressure sensor 5 and the stability of the valve processing and positioning process using the processing and positioning device.

[0047] Referring to Figure 1 and Figure 2 , the number of the pressure sensors 5 can be multiple, and the multiple pressure sensors 5 can be evenly spaced on the anti-slip pad 6, so as to effectively improve the detection progress of the pressure between the two clamping plates 2, enabling the drive motor 32 to more accurately adjust the clamping force of the clamping plate 2 according to the pressure signal output by the pressure sensor 5.
