Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a valve stem transfer mechanism and its detection device. Background Technology

[0002] Existing clamping and transfer mechanisms typically employ three-axis modules. Because these modules use rodless cylinders and linear motors for drive, they occupy a significant amount of space, making the entire clamping process cumbersome. Furthermore, in the transfer of valve stems, given their relatively small size, using a three-axis module would waste installation space.

[0003] For example, the existing publicly available patent, with authorization announcement number CN218595400U and titled "A Three-Axis Lifting Hook Transfer Module Mechanism," includes: an X-axis motion module, a Y-axis motion module, a Z-axis motion module, and a steering assembly. The X-axis motion module has an X-axis guide shaft extending along the X-axis direction. The Y-axis motion module includes a Y-axis guide shaft, a Y-axis fixed seat, a Y-axis motor, and a second linear bearing mounting seat. A steel wire rope is wound around the Y-axis motor and connected to the second linear bearing mounting seat. The second linear bearing mounting seat slides relative to the Y-axis guide shaft. The Z-axis motion module includes a Z-axis guide shaft, a Z-axis motor, and a third linear bearing mounting seat, which is slidably connected to the Z-axis guide shaft. The third linear bearing mounting seat is connected by a steel wire rope that passes around the Z-axis motor. Clearly, this solution occupies a large amount of space, resulting in wasted space.

[0004] Therefore, the technical problem that this application needs to solve is: to reduce the space occupied by the valve stem transfer mechanism. Utility Model Content

Detailed Implementation

[0027] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0028] like Figure 1 and Figure 2 As shown, this embodiment proposes a valve stem transfer mechanism, including a mounting base 11, a horizontal pusher 12, a rotary drive 13, a vertical pusher 14, and a clamping member 15. The horizontal pusher 12 is fixed on the mounting base 11 and has an output end that moves in a horizontal direction. The rotary drive 13 is mounted on the output end of the horizontal pusher 12 via a first support 16 and has a rotatable output end. The vertical pusher 14 is mounted on the output end of the rotary drive 13 via a second support 17 and has an output end that moves in a vertical direction. The clamping member 15 is mounted on the output end of the vertical pusher 14 via a third support 18 and is used to clamp the valve stem 19.

[0029] In this design, the output end of the horizontal pusher 12 moves along the X-axis, and the output end of the vertical pusher 14 moves along the Y-axis. The rotary drive 13 is used to move the clamping member 15 within a certain range on the horizontal plane. The rotary drive 13 has the advantage of saving space and can meet the requirements for movement in the Y-axis direction. The first support 16, the second support 17, and the third support 18 are all L-shaped plate structures. This design has the advantages of small footprint and flexible and convenient transport.

[0030] As one embodiment of this invention, the horizontal pusher 12 and the vertical pusher 14 are respectively adopted as pneumatic cylinders, electric cylinders or hydraulic cylinders.

[0031] Furthermore, the rotary drive 13 is a motor or a rotary cylinder.

[0032] Furthermore, the clamping component 15 is a clamping cylinder or a robotic arm.

[0033] In addition, such as Figures 1 to 4 As shown, this application also proposes a detection device, including the valve stem transfer mechanism described above, and also including a cabinet 20, the upper surface of which has a mounting surface 21, and a mounting base 11 is fixed on the mounting surface 21.

[0034] Furthermore, it also includes a detection device, which is mounted on the mounting surface 21. The detection device includes a positioning clamp 22, which has a positioning groove 23 for mounting the valve stem 19. The positioning groove 23 is used to mount the lever portion 30 in the valve stem 19.

[0035] The testing device includes a mounting plate 31, which is fixed to the mounting surface 21. A fixing plate 33 is fixedly mounted on the mounting plate 31, and a positioning fixture 22 is mounted on the fixing plate 33. This method preliminarily determines whether the valve stem 19 is qualified by observing whether it can be fully assembled in the positioning fixture 22.

[0036] Furthermore, the detection device also includes a limiting seat 24, which has a V-shaped notch 25 for mounting the stem portion 26 of the valve stem 19. The limiting seat 24 is fixed on the fixing plate 33.

[0037] Furthermore, the detection device also includes displacement sensors 27. A displacement sensor 27 is provided on each side of the stem portion 26 of the valve stem 19, and the detection end of the displacement sensor 27 contacts the circumferential surface of the stem portion 26. The displacement sensor 27 is fixed to the mounting plate 31 by the housing 32.

[0038] The shell 32 is rectangular. Figure 4 The single housing 32 shown in the image only has a bottom surface and a first side surface, which are used to illustrate the mounting relationship of the displacement sensor 27.

[0039] The displacement sensor 27 is existing technology, using the GT2-A12K sensor from existing equipment.

[0040] In this scheme, when the valve stem 19 is installed, the stem 26 will squeeze the detection end of the displacement sensor 27 and cause the detection end of the displacement sensor 27 to move. The displacement data is fed back to the control system, and the control system determines whether the valve stem 19 is qualified by judging whether the displacement is within the preset range.

[0041] Alternatively, other types of contact displacement sensors 27 existing in the prior art can be used. A pull-wire displacement sensor 27 existing in the prior art can also be used.

[0042] Furthermore, a waste storage bin 28 is provided on the mounting surface 21, and a valve stem transfer mechanism is used to put the defective valve stems 19 from the testing device into the waste storage bin 28. Specifically, the clamping member 15 in the valve stem transfer mechanism transports the defective valve stems 19, which are jointly mounted on the limiting seat 24 and the positioning clamp 22, into the waste storage bin 28.

[0043] Furthermore, a conveyor is also provided on the mounting surface 21, and a valve stem transfer mechanism is used to feed qualified valve stems 19 from the testing device onto the conveyor belt 29 of the conveyor.

[0044] Specifically, the operation of the valve stem transfer mechanism is controlled by a control system. This control system can include existing PLC control systems or microcontroller control systems.

[0045] The clamping component 15 in the valve stem transfer mechanism transports the qualified valve stem 19, which is jointly installed on the limiting seat 24 and the positioning clamp 22, onto the conveyor belt 29 so that the operator can collect the valve stem 19 at the end of the conveyor belt 29.

[0046] In addition, when the horizontal pusher 12 and the vertical pusher 14 are in the retracted state and the rotary drive 13 is in the initial state, the clamping member 15 is located directly above the conveyor belt 29. If the clamping member 15 releases the valve rod 19, the valve rod 19 can be put onto the conveyor belt 29.

[0047] In this design, after the horizontal pusher 12 extends, the vertical pusher 14 extends, at which point the clamping member 15 can clamp the valve stem 19 on the limiting seat 24 and the positioning fixture 22. When the vertical pusher 14 retracts, the rotation drive 13 operates, causing the clamping member 15 to be positioned above the waste storage bin 28. After the clamping member 15 is released, the defective valve stem 19 falls into the waste storage bin 28.

[0048] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
