Description

Technical Field

[0001] The present invention relates to the technical field of one-way valve assembly, and particularly relates to a detection device for valve body assembly parts. Background Art

[0002] The one-way valve in the brake pipeline is widely used in the brake system, especially the air brake one-way valve. This one-way valve can be used in static applications or dynamic applications with relative movement between components. The quality of the assembled air brake one-way valve is particularly important. As shown in the attached Figure 1 figure, the air brake one-way valve 8 includes a valve body 80, on which a white part 81, a spring 82, and a copper mesh 83 are sequentially assembled. After the air brake one-way valve 8 is assembled, it is necessary to detect the white part, spring, copper mesh, etc. to prevent missing or misassembling. Currently, the common detection method is manual detection. During the manual detection process, safety hazards often occur due to operation errors. At the same time, the quality of the product cannot be uniformly guaranteed, and the work efficiency is low. Summary of the Invention

[0003] In view of the existing technical problems, the present invention provides a detection device for valve body assembly parts to solve the problems in the prior art.

[0004] To achieve the above invention purpose, the present invention provides the following technical solutions:

[0005] A detection device for valve body assembly parts includes a mounting base plate and a mounting turntable. The mounting base plate and the mounting turntable are arranged in parallel, and the mounting base plate is located below the mounting turntable. A white part and spring detection mechanism is provided on the mounting turntable, and a copper mesh detection mechanism is provided on the mounting base plate. The one-way valve is fixed on the mounting turntable through a mounting seat. The white part and spring detection mechanism is located directly above the one-way valve to detect the white part and the spring through this mechanism. The copper mesh detection mechanism is located directly below the one-way valve to detect the copper mesh through this mechanism.

[0006] Preferably, the white part and spring detection mechanism includes a workpiece pressing cylinder fixed on the mounting turntable in the vertical direction. The movable end of the workpiece pressing cylinder is connected to a first bracket in the horizontal direction. A second bracket is connected to the first bracket in the vertical direction. A white part detection telescopic cylinder is provided on the second bracket in the vertical direction. A spring force detection sensor is provided on the first bracket. The upper end of the spring force detection sensor is connected to the movable end of the white part detection telescopic cylinder, and its lower end is connected to a white part detection rod. The white part detection rod passes through a product pressing block and its lower end extends out of the lower end of the product pressing block. The product pressing block passes through the first bracket, and the white part detection rod is located directly above the white part;

[0007] It further includes a white part and spring detection sensor disposed on the installation turntable for detecting the white part and the spring.

[0008] In this solution, during use, it is conveyed to this station by a one-way valve. The workpiece pressing cylinder extends to drive the product pressing block to position and press the workpiece. The white part and spring detection sensor can detect whether the white part and the spring are missing (if the detection is qualified, the equipment continues to run; otherwise, the equipment alarms). The white part detection telescopic cylinder extends, and the white part detection rod moves accordingly. When the white part detection rod contacts the workpiece, the spring force detection sensor feeds back the numerical range of the spring force. If the value fed back by the spring force detection sensor is not a numerical range of a spring force, it means that there is an overloading of the spring, and the product is unqualified; otherwise, the product is qualified.

[0009] Preferably, a bushing is provided on the first bracket. The product pressing block is inserted through the first bracket and the bushing and can move up and down along the first bracket and the bushing.

[0010] Preferably, a limiting convex edge is provided on the outer periphery of the product pressing block, and this limiting convex edge can abut against the lower end face of the first bracket for limiting.

[0011] Preferably, the copper mesh detection mechanism includes a third bracket connected below the installation base plate. A lower sealing cylinder is provided on the third bracket in the vertical direction. The movable end of the lower sealing cylinder is connected to a fourth bracket. A copper mesh detection telescopic cylinder is provided on the fourth bracket in the vertical direction. The movable end of the copper mesh detection telescopic cylinder is connected to a spring support block. A copper mesh ejector rod is connected to the spring support block through a compression spring. The spring force of the compression spring is smaller than the spring force of the spring on the one-way valve. A first sealing pad is sleeved on the copper mesh ejector rod for sealing the lower sealing surface of the one-way valve. A connecting block is also connected to the copper mesh ejector rod. The lower end of the compression spring abuts against the spring support block, and its upper end abuts against the connecting block. A magnetic moving block is provided on the connecting block, and this magnetic moving block cooperates with a magnetic block displacement detection sensor.

[0012] In this solution, during use, the lower sealing cylinder acts to drive the first sealing pad to seal and support the lower sealing surface of the one-way valve. The copper mesh detection telescopic cylinder extends to drive the copper mesh ejector rod to move. When the copper mesh ejector rod contacts the copper mesh, since the spring force of the compression spring is smaller than the spring force of the spring in the product, the copper mesh ejector rod is reversely compressed. The connecting block drives the magnetic moving block to move downward. If the magnetic block displacement detection sensor detects a distance within the qualified range, it means that the product has installed the copper mesh. If there is no reverse compression movement during the extension of the copper mesh ejector rod, it means that the copper mesh is not installed, indicating that the product is unqualified.

[0013] Preferably, a linear bearing mounting seat is provided at the upper end of the fourth bracket. The first gasket is connected to the linear bearing mounting seat. A linear bearing is provided on the linear bearing mounting seat, and the copper mesh ejector rod is movably inserted through the linear bearing.

[0014] Preferably, it further includes an airtightness detection mechanism. The airtightness detection mechanism includes a side-sealing longitudinal cylinder disposed vertically on the mounting base plate. The movable end of the side-sealing longitudinal cylinder is connected to a fifth bracket. A side-sealing transverse cylinder is provided horizontally on the fifth bracket. The movable end of the side-sealing transverse cylinder is connected to a sixth bracket. A pipe joint is provided on the sixth bracket. One end of the pipe joint is communicated with a flow sensor through a pipeline, and the other end is connected with a second gasket for sealing the side sealing surface of the one-way valve. The flow sensor is electrically connected to a pressure display.

[0015] In this solution, during use, the side-sealing longitudinal cylinder extends, the side-sealing transverse cylinder extends, and the second gasket seals the side sealing surface of the one-way valve; at the same time, the lower-sealing cylinder extends, and the first gasket seals the lower sealing surface of the workpiece. The device is ventilated, and the product is monitored in real time through the flow sensor and the pressure display. If a yellow alarm signal appears on the pressure display, the assembled product is unqualified, otherwise it is qualified.

[0016] Preferably, blowing assemblies are also distributed on the mounting base plate.

[0017] With such a setting, dust and the like falling on the device can be blown off.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the automatic detection of the internal fittings of the one-way valve body, this solution stably and reliably realizes the assembly of the product, overcomes the influence of manual detection on the product quality, reduces the labor intensity of personnel and the labor cost, improves the stability of the product, greatly improves the overall manufacturing level and quality of the production line, and at the same time, this solution can adapt to the detection of one-way valves of different specifications and has a wider application range.

[0029] As shown in the attached Figure 2 - attached Figure 7 A valve body assembly detection device as shown includes a mounting base plate 5 and a mounting turntable 6. The mounting base plate 5 and the mounting turntable 6 are arranged in parallel, both parallel to the horizontal plane, and the mounting base plate 5 is located below the mounting turntable 6. A white part and spring detection mechanism 1 is provided on the mounting turntable 6, and a copper mesh detection mechanism 2 is provided on the mounting base plate 5. The one-way valve 8 is fixed on the mounting turntable 6 through a mounting seat. The white part and spring detection mechanism 1 is located directly above the one-way valve 8, and the white part 81 and the spring 82 are detected through the white part and spring detection mechanism 1. The copper mesh detection mechanism 2 is located directly below the one-way valve 8, and the copper mesh 83 is detected through the copper mesh detection mechanism 2.

[0030] Please refer to Figure 3 and Figure 4, the blank and spring detection mechanism 1 includes a workpiece pressing cylinder 11 fixed vertically on the installation turntable 6. The movable end of the workpiece pressing cylinder 11 is horizontally connected with a first bracket 12. A second bracket 13 is vertically connected to the first bracket 12. A blank detection telescopic cylinder 14 is vertically arranged on the second bracket 13. A spring force detection sensor 15 and a bushing 19 are arranged on the first bracket 12. The upper end of the spring force detection sensor 15 is connected with the movable end of the blank detection telescopic cylinder 14, and its lower end is connected with a blank detection rod 17. The blank detection rod 17 is arranged through the product pressing block 16, and its lower end extends out of the lower end of the product pressing block 16. The product pressing block 16 is arranged through the first bracket 12 and the bushing 19 and can move up and down along the first bracket 12 and the bushing 19. A limiting convex edge is arranged on the outer periphery of the product pressing block 16, and the limiting convex edge can abut against the lower end face of the first bracket 12 for limiting.

[0031] The blank detection rod 17 is located directly above the blank 81. A blank and spring detection sensor 18 for detecting the blank 81 and the spring 82 is also arranged on the installation turntable 6.

[0032] After the product is conveyed to this station, the workpiece pressing cylinder 11 extends to drive the product pressing block 16 to position and press the workpiece. The blank and spring detection sensor 18 detects whether the blank 81 and the spring 82 are missing (if the detection is qualified, the equipment continues to run; otherwise, the equipment alarms). The blank detection telescopic cylinder 14 extends, and the blank detection rod 17 reciprocates in the inner hole of the bushing 19. When the blank detection rod 17 contacts the workpiece, the spring force detection sensor 15 feeds back the numerical range of the spring force. If the value fed back by the spring force detection sensor 15 is not a numerical range of a spring force, it means that the spring is overloaded, and the product is unqualified; otherwise, the product is qualified.

[0033] Please refer to Figure 5 and Figure 6 , the copper mesh detection mechanism 2 includes a third bracket 20 connected below the installation base plate 5. A lower sealing cylinder 21 is vertically arranged on the third bracket 20. The movable end of the lower sealing cylinder 21 is connected with a fourth bracket 22. A copper mesh detection telescopic cylinder 23 is vertically arranged on the fourth bracket 22. The movable end of the copper mesh detection telescopic cylinder 23 is connected with a spring support block 24. A copper mesh ejector rod 26 is connected to the spring support block 24 through a compression spring 25. The spring force of the compression spring 25 is less than the spring force of the spring 82 on the one-way valve 8. A first sealing gasket 27 is sleeved on the copper mesh ejector rod 26 for sealing the lower sealing surface of the one-way valve. A connecting block 28 is also connected to the copper mesh ejector rod 26. The lower end of the compression spring 25 abuts against the spring support block 24, and its upper end abuts against the connecting block 28. A magnetic moving block 291 is arranged on the connecting block 28, and the magnetic moving block 291 cooperates with the magnetic block displacement detection sensor 29 to detect the copper mesh.

[0034] The upper end of the fourth bracket 22 is provided with a linear bearing mounting seat 201. A first sealing gasket 27 is connected to the linear bearing mounting seat 201. A linear bearing 202 is arranged on the linear bearing mounting seat 201. The copper mesh ejector rod 26 is movably inserted through the linear bearing 202.

[0035] In order to ensure the stability of the vertical movement, a slide rail is arranged on the mounting base plate 5 in the vertical direction. The fourth bracket 22 is slidably connected to the slide rail through a slider.

[0036] When detecting the copper mesh, the lower sealing cylinder 21 extends upward. The first sealing gasket 27 seals and supports the workpiece. The copper mesh detection telescopic cylinder 23 extends, driving the copper mesh ejector rod 26 to slide in the linear bearing 202. When the copper mesh ejector rod 26 contacts the copper mesh, since the spring force of the compression spring is smaller than the spring force of the spring in the product, the copper mesh ejector rod 26 is compressed in the reverse direction. The connecting block drives the magnetic moving block to move downward. The magnetic block displacement detection sensor detects that the moving distance is within the qualified range, indicating that the copper mesh has been installed in the product. If there is no reverse compression movement during the extension of the copper mesh blocking rod, it means that the copper mesh is not installed and the product is unqualified.

[0037] Please refer to Figure 7 and Figure 2 The present invention further includes an airtightness detection mechanism 3. The airtightness detection mechanism 3 includes a side-sealing longitudinal cylinder 31 arranged on the mounting base plate 5 in the vertical direction. The movable end of the side-sealing longitudinal cylinder 31 is connected with a fifth bracket 32. A side-sealing transverse cylinder 33 is arranged on the fifth bracket 32 in the horizontal direction. The movable end of the side-sealing transverse cylinder 33 is connected with a sixth bracket 34. A pipe joint 35 is arranged on the sixth bracket 34. One end of the pipe joint 35 is communicated with a flow sensor 37 through a pipeline, and the other end is connected with a second sealing gasket 36 for sealing the side sealing surface of the one-way valve. The flow sensor 37 is electrically connected with a pressure display 38. In order to ensure the stability of the movement, a linear guide rail is arranged on the fifth bracket 32 in the horizontal direction. The sixth bracket 34 is slidably connected to the linear guide rail through a slider.

[0038] In order to avoid the influence of dust scattering on the equipment, a blowing component 4 is also distributed on the mounting base plate 5. The blowing component 4 includes a mounting frame fixed on the mounting base plate, and a dust blowing nozzle is arranged on the mounting frame. Of course, it can also be other structures that can be realized.

[0039] When performing the airtightness detection, the side-sealing longitudinal cylinder 31 extends, the side-sealing transverse cylinder 33 extends, and the second gasket 36 seals the side plugging surface of the workpiece; at the same time, the lower-sealing cylinder extends, and the first gasket 27 seals the lower plugging surface of the workpiece. Then, the equipment is ventilated, and the gas enters the check valve after passing through the flow sensor, the pipe joint, and the second gasket. The product is monitored in real time through the flow sensor and the pressure display. If a yellow alarm signal appears on the pressure display, the assembled product is unqualified; otherwise, it is qualified.

[0040] This solution can detect whether the white parts, springs, and copper meshes of the product are missing or overloaded by the mechanism in parallel. At the same time, it can test the airtightness of the assembled product, and through the integration of the PLC and the automation mechanism, it greatly improves the overall manufacturing level and quality of the production line.

It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
