Description

Technical Field

[0001] A follow-up detection screening module for valve body production and conveying devices relates to the field of valve body production, processing and detection technology. Background Technology

[0002] The valve shell is the outer shell of the valve body, used in conjunction with the valve core for regulation and sealing. The overall performance of the valve body is affected by the fit between the valve shell and the valve body; therefore, the inner wall of the valve shell needs to be inspected during the valve shell production process. Current inspection methods involve inserting inspection equipment into the valve shell to check for specifications, dimensions, cracks, and damage on the inner wall. However, this requires manual operation and controlled screening, which is not only time-consuming and labor-intensive but also prone to false positives and false negatives, significantly hindering the production efficiency of valve shells. Therefore, how to achieve automated inspection and screening of valve shells is a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the current detection method is to insert a detection device into the valve body to detect the specifications, dimensions, cracks and damage of the inner wall of the valve body. However, because it requires manual operation and control of the screening, it is not only time-consuming and labor-intensive, but also prone to false detection and missed detection, which greatly restricts the production and processing efficiency of the valve body.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a follow-up detection screening module applied to a valve shell production conveying device, including a horizontal main frame, a first electrically controlled conveyor belt and a second electrically controlled conveyor belt installed inside the horizontal main frame, side guide frames symmetrically mounted on the inner walls of both sides of the horizontal main frame, an electrically controlled side clamping device movably mounted inside the side guide frame, an electrically controlled flipping detection module installed on the electrically controlled side clamping device, and an elastic buffer guiding platform mounted inside the horizontal main frame between the first electrically controlled conveyor belt and the second electrically controlled conveyor belt; the electrically controlled side clamping device includes an electrically controlled transverse lead screw movably mounted inside the side guide frame, an internally threaded translation block threaded onto the outside of the electrically controlled transverse lead screw, a lateral assembly frame fixed on the outer surface of the internally threaded translation block, an elastic flipping clamping arm movably mounted inside the lateral assembly frame, and an arc-shaped electromagnet fixed on the arc-shaped side wall of the elastic flipping clamping arm.

[0005] Furthermore, the electrically controlled flip-type detection module includes an electrically controlled bottom flip frame movably mounted on the bottom of the internal thread translation block, an arc-shaped guide rail welded and fixed to the side wall of the electrically controlled bottom flip frame, an arc-shaped adjustment frame slidably inserted into the arc-shaped guide rail, a lateral telescopic cylinder fixed to the inner side of the arc-shaped adjustment frame, an electrically controlled telescopic head installed inside the lateral telescopic cylinder, an optical detection probe fixed to the outer arc-shaped surface of the electrically controlled telescopic head, and an adjustment motor fixed to the outer wall of the arc-shaped adjustment frame.

[0006] Furthermore, the side assembly frame has symmetrically opened circular assembly through holes inside, and the elastic flipping clamping arm includes an arc-shaped clamping arm with an assembly shaft at the connecting end and a reset spring plate installed inside the side assembly frame. The arc-shaped clamping arm is inserted into the circular assembly through hole through the assembly shaft and is movably connected to the side assembly frame.

[0007] Furthermore, an arc-shaped toothed groove is provided on the outer arc-shaped surface of the arc-shaped adjustment frame, and the adjustment motor is driven by the drive gear on the adjustment shaft meshing with the arc-shaped toothed groove.

[0008] Furthermore, the side guide frame has a lateral flip-up notch that cooperates with the electronically controlled flip-up detection module.

[0009] Furthermore, a push-button control switch is fixed on the inner arc-shaped surface of the elastic flipping clamp arm.

[0010] Furthermore, the bottom of the internal thread translation block is provided with a bottom flip assembly groove, the lower surface of the internal thread translation block has a bottom assembly frame, and the electrically controlled bottom flip frame includes a flip adjustment bracket movably installed inside the bottom flip assembly groove via a top bracket and a flip adjustment support rod movably connected to the bottom assembly frame. The telescopic section of the flip adjustment support rod is movably connected to the side wall of the flip adjustment bracket.

[0011] Furthermore, a pressure control switch is installed on the side wall of the flip-adjustment bracket.

[0012] Furthermore, the electrically controlled telescopic head includes an electrically controlled eccentric adjustment screw slidably installed inside the lateral telescopic cylinder, an internally threaded telescopic cylinder threaded onto the outside of the electrically controlled eccentric adjustment screw, and a lighting lamp body fixed to the top of the internally threaded telescopic cylinder.

[0013] The beneficial effects of this invention are as follows: The follow-up detection and screening module of this invention, applied to a valve shell production conveying device, integrates the detection mechanism directly into the conveying equipment, automatically completing the detection operation during the conveying process without manual intervention, saving time and effort, and greatly improving detection efficiency. Through the reciprocating design, it can automatically separate from the valve shell after detection and then reset to the initial position to await the next valve shell assembly. The sequential detection method avoids missed and incorrect detections. During the detection process, the automatic separation of the detection structure automatically separates unqualified products by gravity, improving screening efficiency. The follow-up detection does not affect… Normal valve body transport ensures production efficiency; the electrically controlled bottom-tilting frame provides bottom support for the valve body, ensuring structural stability and testing accuracy during internal inspection; the split-assembly design of the arc-shaped guide rail and arc-shaped adjustment frame forms a ring-shaped drive unit at the lower opening of the valve body, facilitating the adjustment of the motor to drive the electrically controlled telescopic head and the optical detection probe on its outer arc-shaped surface for ring and longitudinal adjustment, ensuring that the detection range covers the entire inner wall of the valve body; the installation of arc-shaped electromagnets on the arc-shaped sidewalls of the elastic tilting clamps facilitates magnetic adsorption linkage between the two sides of the valve body, improving connection stability.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Figure 1 , Figure 2 , Figure 3 and Figure 4 The illustrated follow-up detection screening module for valve body production conveying device includes a horizontal main frame 1, a first electrically controlled conveyor belt 2 and a second electrically controlled conveyor belt 3 installed inside the horizontal main frame 1. Side guide frames 4 are symmetrically mounted on the inner walls of both sides of the horizontal main frame 1. Electrically controlled side clamping devices 5 are movably mounted inside the side guide frames 4. Electrically controlled flipping detection modules 6 are installed on the electrically controlled side clamping devices 5. An elastic buffer guiding platform 7 is mounted inside the horizontal main frame 1 between the first electrically controlled conveyor belt 2 and the second electrically controlled conveyor belt 3.

[0023] The first electrically controlled conveyor belt 2 and the second electrically controlled conveyor belt 3 are existing technologies used for the translational transport of valve bodies.

[0024] To facilitate magnetic fixation, the electrically controlled side clamping device 5 includes an electrically controlled transverse lead screw 51 movably mounted inside the side guide frame 4, an internal thread translation block 52 threaded onto the outside of the electrically controlled transverse lead screw 51, a lateral assembly frame 53 fixed on the outer surface of the internal thread translation block 52, an elastic flipping clamping arm 54 movably mounted inside the lateral assembly frame 53, and an arc-shaped electromagnet 55 fixed on the arc-shaped sidewall of the elastic flipping clamping arm 54.

[0025] The arc-shaped electromagnet 55 is existing technology. It generates magnetism when energized, fixing the elastic flipping clamp 54 to both sides of the valve housing. This secures the electrically controlled side-mounted clamping device 5 to the outer wall of the valve housing. The electrically controlled side-mounted clamping device 5 then moves horizontally along the side guide frame 4. When the first electrically controlled conveyor belt 2 moves the valve housing horizontally inside the horizontal main frame 1, it is then moved by the electrically controlled side-mounted clamping device 5 to the second electrically controlled conveyor belt 3. When the electrically controlled flipping detection module 6 detects an unsuitable valve housing, the electrically controlled side-mounted clamping device 5 separates, and the electrically controlled flipping detection module 6 flips downwards to reset, causing the valve housing to fall onto the elastic buffer guide platform 7. After buffering, the elastic buffer guide platform 7 tilts to one side, allowing the material to be discharged from the lateral discharge port located on one side of the horizontal main frame 1, completing the screening process. The bottom of the elastic buffer guide platform 7 is equipped with a bottom shock-absorbing spring. A bottom limiting frame is installed on the bottom surface of the horizontal main frame 1 on the side of the bottom shock-absorbing spring. When the elastic buffer guide platform 7 descends, the bottom on the side away from the lateral discharge port is limited by the upper end of the bottom limiting frame, which facilitates the formation of inclined guide.

[0026] To facilitate flipping, telescopic, and rotational adjustments, the electrically controlled flipping detection module 6 includes an electrically controlled bottom flipping frame 61 movably mounted on the bottom of the internally threaded translation block 52, an arc-shaped guide rail 62 welded and fixed to the side wall of the electrically controlled bottom flipping frame 61, an arc-shaped adjustment frame 63 slidably inserted into the arc-shaped guide rail 62, a lateral telescopic cylinder 64 fixed to the inner side of the arc-shaped adjustment frame 63, an electrically controlled telescopic head 65 installed inside the lateral telescopic cylinder 64, an optical detection probe 66 fixed to the outer arc-shaped surface of the electrically controlled telescopic head 65, and an adjustment motor 67 fixed to the outer wall of the arc-shaped adjustment frame 63.

[0027] The optical detection probe 66 and the regulating motor 67 are existing technologies. The optical detection probe 66 uses existing photoelectric technology to optically scan the inner wall of the valve body, thereby detecting the distance between the optical detection probe 66 and the inner wall of the valve body, thus determining the inner diameter of the valve body, and then detecting and identifying cracks and damage on the inner wall of the valve body, thereby improving the detection effect. The regulating motor 67 is used to drive the arc-shaped regulating frame 63 to slide and adjust along the arc-shaped guide rail 62, thereby performing circumferential adjustment inside the valve body.

[0028] To facilitate flexible assembly, the side assembly frame 53 has symmetrically arranged circular assembly through holes. The flexible flipping clamping arm 54 includes an arc-shaped clamping arm 541 with an assembly shaft at the connecting end and a reset spring piece 542 installed inside the side assembly frame 53. The arc-shaped clamping arm 541 is inserted into the circular assembly through hole through the assembly shaft and is movably connected to the side assembly frame 53.

[0029] One side of the reset spring 542 is fixed to the inner wall of the lateral assembly frame 53, and the other side is pressed against the side wall of the arc-shaped clamping arm 541, thereby controlling the arc-shaped clamping arm 541 to elastically flip and reset.

[0030] The outer arc-shaped surface of the arc-shaped adjustment frame 63 is provided with an arc-shaped toothed groove 68, and the adjustment motor 67 is driven by the drive gear 69 on the adjustment shaft meshing with the arc-shaped toothed groove 68.

[0031] To facilitate bottom flipping, the side guide frame 4 has a side flipping notch 8 that cooperates with the electronically controlled flipping detection module 6.

[0032] In order to control the start of the arc electromagnet 55, a push-type control switch 56 is fixed on the arc-shaped surface of the inner side of the elastic flipping clamp 54.

[0033] In the initial state, one side of the elastic flipping clamp arm 54 lies horizontally on the feed port side of the first electrically controlled conveyor belt 2. When the valve body is pushed and pressed by the first electrically controlled conveyor belt 2 against the push-button control switch 56, the push-button control switch 56 controls the electrically controlled bottom flipping frame 61 to flip upward, thereby ensuring the stability of the bottom support force of the valve body. After the electrically controlled bottom flipping frame 61 flips into place, the push-button control switch 56 also controls the arc-shaped electromagnet 55 to start. At this time, the arc-shaped electromagnet 55 firmly holds the valve body on the elastic flipping clamp arm 54, and the internally threaded translation blocks 52 located on both sides can then drive the valve body to translate and adjust.

[0034] To facilitate bottom flip adjustment, the bottom of the internal thread translation block 52 is provided with a bottom flip assembly groove, and the lower surface of the internal thread translation block 52 has a bottom assembly frame 57. The electrically controlled bottom flip frame 61 includes a flip adjustment bracket 611 that is movably installed inside the bottom flip assembly groove via a top bracket and a flip adjustment support rod 612 that is movably connected to the bottom assembly frame 57. The telescopic section of the flip adjustment support rod 612 is movably connected to the side wall of the flip adjustment bracket 611.

[0035] The flip-adjustable strut 612 is existing technology.

[0036] To facilitate reset control, a pressure control switch 613 is installed on the side wall of the flip adjustment bracket 611.

[0037] The pressure control switch 613 is existing technology, which controls the pressure change at the bottom of the valve body. When the tilting adjustment support rod 612 extends to control the tilting adjustment bracket 611 to tilt upward, it squeezes and supports the bottom of the valve body. After the pressure reaches the maximum set value, the pressure control switch 613 controls the tilting adjustment support rod 612 to close. When the valve body is transferred to the second electrically controlled conveyor belt 3, the pressure of the pressure control switch 613 begins to decrease. The pressure control switch 613 controls the tilting adjustment support rod 612 to retract, and controls the tilting adjustment bracket 611 to tilt downward. At the same time as the tilting adjustment support rod 612 retracts, the electrically controlled telescopic head 65 retracts into the lateral telescopic cylinder 64, completing the complete reset of the detection mechanism.

[0038] To facilitate telescopic adjustment and internal supplemental lighting, the electrically controlled telescopic head 65 includes an electrically controlled eccentric adjustment screw 651 that is slidably installed inside the lateral telescopic cylinder 64, an internally threaded telescopic cylinder 652 that is threaded onto the outside of the electrically controlled eccentric adjustment screw 651, and a lighting lamp body 653 that is fixed to the top of the internally threaded telescopic cylinder 652.

[0039] The electrically controlled eccentric adjusting screw 651 includes a built-in adjusting motor fixed inside one end of the lateral telescopic cylinder 64 and an eccentric screw axially fixed to the adjusting shaft of the built-in adjusting motor via a coupling. The built-in adjusting motor drives the eccentric screw to rotate, thereby driving the internal thread telescopic cylinder 652 to extend and retract along the inside of the lateral telescopic cylinder 64. Because of the eccentric design, the internal thread telescopic cylinder 652 will not rotate inside the lateral telescopic cylinder 64. The lighting body 653 is existing technology, which illuminates the inner wall of the valve body by energizing it, thereby improving the detection effect of the optical detection probe 66.
