Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valve detection, in particular to an electromagnetic valve detection device. Background Art

[0002] The solenoid valve is an industrial device controlled by electromagnetics. It is a basic automation component used to control fluids and is an actuator. The solenoid valve used in automobile braking systems has special functionality and extremely important sealing properties. The sealing requirements are relatively strict. Solenoid valves need to be sampled and tested after production to test their airtightness under strong pressure. The testing of solenoid valves requires a testing device.

[0003] A Chinese patent with announcement number CN210487166U discloses a post-production sealing test device for a solenoid valve, comprising a base, a solenoid valve mounted on the upper end of the base through a socket, and a double-rod air pump welded to the upper end of the base; in the post-production sealing test device for a solenoid valve, an air bag is inflated at a uniform speed into the interior of the solenoid valve through an air hole on a second sealing plate, the sealing air bag expands rapidly, the side wall of the sealing air bag is tightly attached to the side wall of the stepped hole, the stepped hole is blocked, and when the air pressure inside the solenoid valve is high, due to the internal and external air pressure difference, the air pressure will push the second sealing plate closer to the first sealing plate, so that the side wall of the sealing air bag between the second sealing plate and the first sealing plate is more tightly attached to the side wall of the stepped hole, thereby further strengthening the sealing of the solenoid valve port, ensuring the airtightness of the solenoid valve port during the inflation process, thereby ensuring the accuracy of the detection and ensuring the product quality.

[0004] In the above technology, the airtightness of the solenoid valve port during the inflation process is ensured by sealing the solenoid valve port. However, when the solenoid valve is tested for airtightness, the solenoid valve is not fixed and thus shakes during the testing process, thereby affecting the test result of the airtightness of the solenoid valve. If the solenoid valve is held by hand, not only more labor is required but also the arm will ache after a long time and the stability of the solenoid valve cannot be guaranteed.

[0005] Therefore, in order to solve the above problems, a solenoid valve detection device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Reference Figure 1-Figure 6 As shown, a solenoid valve detection device of the utility model comprises a detection platform 1; a mounting frame 2 is fixedly connected to the top of the detection platform 1, and a detection equipment body 6 is arranged below the mounting frame 2; a solenoid valve body 7 is arranged directly below the detection equipment body 6, and a fixing structure is arranged on both sides of the solenoid valve body 7, and the fixing structure comprises two first clamping plates 8 arranged above the detection platform 1; a second clamping plate 9 is arranged on the inner side of the first clamping plate 8; a connecting block 18 is fixedly connected to the bottom of the first clamping plate 8, and a first rack 14 is fixedly connected to the bottom of the connecting block 18, and a second gear 13 is arranged in the middle of the two first racks 14, and the first rack 14 is meshed with the second gear 13; a driving mechanism is arranged below the second gear 13, and the driving mechanism is used to drive the second gear 13 to rotate; a pressure sensor 25 is fixedly connected to the top of the detection platform 1, and the solenoid valve body 7 is placed on the top of the pressure sensor 25.

[0029] During operation, the solenoid valve body 7 is first placed on the pressure sensor 25. In order to solve the problem that the solenoid valve body 7 is prone to shaking during the detection process, it is necessary to start the driving mechanism. Under the action of the driving mechanism, the second gear 13 rotates. Since the second gear 13 is meshed with the two first racks 14, during the rotation of the second gear 13, the second gear 13 drives the two first racks 14 to move in opposite directions, the first rack 14 drives the connecting block 18 to move in opposite directions, the connecting block 18 drives the first clamping plate 8 to move in opposite directions, the first clamping plate 8 drives the second clamping plate 9 to move in opposite directions until the first clamping plate 8 is in close contact with the bottom of the solenoid valve body 7, the second clamping plate 9 is in close contact with the middle of the solenoid valve, and the movement stops, thereby realizing the function of fixing the solenoid valve body 7, and solving the problem that the solenoid valve body 7 is prone to shaking during the detection process; after the fixing is completed, it can be detected by the detection equipment body 6.

[0030] Further, such as Figure 3 and Figure 4 As shown, the driving mechanism includes a base plate 10 fixedly connected to the bottom of the detection platform 1; the top of the base plate 10 is rotatably connected to a rotating rod 11 through a rotating shaft; the second gear 13 is fixedly connected to the top of the rotating rod 11; the outer side wall of the bottom end of the rotating rod 11 is fixedly connected to a first gear 12; a second rack 15 is provided on one side of the first gear 12, the second rack 15 is meshed with the first gear 12, the bottom of the second rack 15 is fixedly connected to a limit block 16, and the limit block 16 is slidably connected to the base plate 10; the top of the base plate 10 is fixedly connected to an electric push rod 17, and the output end of the electric push rod 17 is fixedly connected to one end of the second rack 15.

[0031] When working, when the driving mechanism is working, by turning on the electric push rod 17, the electric push rod 17 drives the second rack 15 to move through the output end, and the second rack 15 is meshed with the first gear 12, so the second rack 15 drives the first gear 12 to move, the first gear 12 drives the rotating rod 11 to rotate, and the rotating rod 11 drives the second gear 13 to rotate. When the electric push rod 17 is extended, the second rack 15 moves forward, the second rack 15 drives the first gear 12 to rotate counterclockwise, the first gear 12 drives the second gear 13 to rotate counterclockwise, and the second gear 13 drives the first rack 14 One end of the fixed connecting block 18 moves in the direction of the second gear 13, conversely, the second gear 13 drives the first rack 14 One end of the fixed connecting block 18 moves in the direction away from the second gear 13; during the movement of the second rack 15, the limit block 16 slides on the bottom plate 10 to ensure the stability of the second rack 15.

[0032] Further, such as Figure 1 and Figure 2As shown, a cylinder 4 is fixedly connected to the mounting frame 2, and a lifting plate 3 is fixedly connected to the output end of the cylinder 4; the detection equipment body 6 is fixedly connected to the bottom of the lifting plate 3, and four pillars 5 are fixedly connected to the top of the detection platform 1, and the pillars 5 are arranged at the four corners of the lifting plate 3, and the lifting plate 3 is slidably connected to the four pillars 5.

[0033] During operation, after the solenoid valve body 7 is fixed, the cylinder 4 needs to be opened. The cylinder 4 drives the lifting plate 3 to move downward through the output end, and the lifting plate 3 drives the detection equipment body 6 to move downward. When the detection equipment body 6 is in sealing contact with the solenoid valve body 7, detection can be carried out. At this time, the pressure sensor 25 always monitors the pressure of the detection equipment body 6 on the solenoid valve body 7 to avoid excessive or insufficient pressure, which causes detection errors.

[0034] Further, such as Figure 5 and Figure 6 As shown, one end of two sliding columns 20 are fixedly connected to the side walls of the second clamping plate 9, and the other ends of the sliding columns 20 slide through the first clamping plate 8. The outer sides of the sliding columns 20 are sleeved with first springs 21, and the first springs 21 are fixedly connected between the outer side wall of the first clamping plate 8 and the inner side wall of the end of the sliding column 20; the outer sides of the sliding columns 20 are sleeved with second springs 22, and the second springs 22 are fixedly connected between the inner side wall of the first clamping plate 8 and the outer side wall of the second clamping plate 9.

[0035] During operation, the first clamping plate 8 moves toward the middle at the same time, and the first clamping plate 8 is in close contact with the bottom end of the solenoid valve body 7. When the middle valve body of the solenoid valve body 7 contacts the second clamping plate 9, under the action of the first spring 21 and the second spring 22, it is convenient to clamp the middle valve body position of the solenoid valve body 7 of different sizes, and in the detection process, it plays a buffering role to prevent excessive pressure and damage to the outer shell of the solenoid valve body 7.

[0036] Further, such as Figure 5 As shown, the inner side walls of the second clamping plate 9 are provided with anti-slip grooves 24 , and the anti-slip grooves 24 are used to prevent the solenoid valve body 7 and the second clamping plate 9 from sliding.

[0037] During operation, the inner side walls of the second clamping plate 9 are provided with anti-slip grooves 24 to prevent the electromagnetic valve body 7 and the second clamping plate 9 from sliding and causing detection errors.

[0038] Further, such as Figure 4 As shown, the two first clamping plates 8 are symmetrical with respect to the second gear 13 , and the two first racks 14 are arranged in parallel.

[0039] During operation, the first clamping plate 8 is symmetrical with respect to the second gear 13 to facilitate synchronous clamping of the solenoid valve body 7, ensuring that the solenoid valve body 7 is located in the middle of the testing platform 1 during testing. The two first racks 14 are arranged in parallel and on both sides of the second rack 15 to facilitate synchronous reverse movement.

[0040] Further, such as Figure 3 and Figure 6 As shown, a slider 19 is fixedly connected to the bottom of each of the first clamping plates 8 , and two slide grooves 24 are provided on the top of each of the inspection platforms 1 , in which each of the sliders 19 slides.

[0041] During operation, when the first clamping plate 8 is in motion, the first clamping plate 8 drives the slider 19 to move, and the slider 19 slides in the slide groove 24 , and the slider 19 limits the first clamping plate 8 in the horizontal direction.

[0042] Further, such as Figure 3 and Figure 6 As shown, the detection platform 1 is provided with two sliding openings 23 , and the connecting blocks 18 are arranged in a cross shape, and the connecting blocks 18 all slide in the sliding openings 23 .

[0043] During operation, when the first rack 14 is in motion, the first rack 14 drives the connecting block 18 to slide, and the connecting block 18 slides in the sliding opening 23. The connecting block 18 limits the first rack 14 and the first clamping plate 8 in the horizontal direction. The connecting block 18 is set to a cross shape, and the connecting block 18 maintains the stability of the first rack 14.

[0044] Working principle: First, the solenoid valve body 7 is placed on the pressure sensor 25. In order to solve the problem that the solenoid valve body 7 is prone to shaking during the detection process, the electric push rod 17 is turned on. The electric push rod 17 drives the second rack 15 to move through the output end. The second rack 15 is meshed with the first gear 12, so the second rack 15 drives the first gear 12 to move, the first gear 12 drives the rotating rod 11 to rotate, and the rotating rod 11 drives the second gear 13 to rotate. During the rotation of the second gear 13, since the second gear 13 is meshed with the two first racks 14, during the rotation of the second gear 13, the second gear 13 drives the two first racks 14 to move in opposite directions, the first rack 14 drives the connecting block 18 to move in opposite directions, the connecting block 18 drives the first clamping plate 8 to move in opposite directions, the first clamping plate 8 drives the second clamping plate 9 to move in opposite directions until the first clamping plate 8 is in close contact with the bottom of the solenoid valve body 7, and the second clamping plate 9 is in close contact with the solenoid valve The middle part of the electromagnetic valve body 7 is in close contact with the first clamping plate 8 and stops moving, thereby realizing the function of fixing the electromagnetic valve body 7, and solving the problem that the electromagnetic valve body 7 is prone to shaking during the detection process; when the first clamping plate 8 moves toward the middle at the same time, the first clamping plate 8 is in close contact with the bottom end of the electromagnetic valve body 7, and when the middle valve body of the electromagnetic valve body 7 contacts the second clamping plate 9, under the action of the first spring 21 and the second spring 22, it is convenient to clamp the middle valve body position of the electromagnetic valve body 7 of different sizes, and in the detection process, it plays a buffering role to prevent excessive pressure and damage to the outer shell of the electromagnetic valve body 7; after the fixing is completed, the cylinder 4 can be opened, and the cylinder 4 drives the lifting plate 3 to move downward through the output end, and the lifting plate 3 drives the detection device body 6 to move downward, and when the detection device body 6 is in sealing contact with the electromagnetic valve body 7, the detection can be carried out, and at this time, the pressure sensor 25 always monitors the pressure of the detection device body 6 on the electromagnetic valve body 7 to avoid excessive or insufficient pressure, which causes detection errors.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
