Description

Technical Field

[0001] This application relates to the technical field of CDC valve testing, and in particular to an oil removal device for CDC valve testing. Background Art

[0002] The CDC shock absorption system is an important part of modern automotive suspension systems. It can improve the handling and comfort of vehicles by adjusting the damping force of shock absorbers in real time. As the core component of this system, the performance of the CDC solenoid valve directly affects the shock absorption effect and plays an important role in the CDC shock absorption system. Nowadays, with the development of the automotive industry, the requirements for the accuracy and reliability of CDC solenoid valves in the industry are getting higher and higher. Therefore, special testing equipment is needed to ensure that their performance meets the design requirements.

[0003] In the prior art, generally during the performance detection stage of the CDC solenoid valve, power is supplied to the CDC solenoid valve and oil is introduced. By detecting the magnitude of the current, the pressure, and the flow rate of the oil in the CDC solenoid valve, it is determined whether the performance of the CDC solenoid valve is normal. After the performance detection, there is usually a small amount of oil stain remaining on the surface and inside the holes of the CDC solenoid valve. Therefore, relevant personnel are required to clean the oil stains on the surface and inside the holes of the CDC solenoid valve to ensure that the tooling, trays carrying the CDC solenoid valve, and subsequent conveying tracks are not contaminated.

[0004] Regarding the above related technologies, in the prior art, generally, a worker holds the tested CDC solenoid valve in one hand and a blow gun in the other hand, and aligns the air outlet end of the blow gun with the surface and inside the holes of the CDC solenoid valve to blow out the remaining oil stains on the surface and inside the holes of the CDC solenoid valve. This greatly reduces the oil removal efficiency of the CDC solenoid valve, so it needs to be improved. Summary of the Invention

[0005] In order to improve the oil removal efficiency of the CDC solenoid valve, this application provides an oil removal device for CDC valve testing.

[0006] An oil removal device for CDC valve testing provided by this application adopts the following technical solutions: An oil removal device for CDC valve testing includes a frame. A conveying mechanism and an oil removal mechanism are further arranged on the frame. The oil removal mechanism includes a lifting cover, a lifting component, and a blowing component. The bottom of the lifting cover is open. The lifting component is used to drive the lifting cover to move up and down. The conveying mechanism is used to convey the CDC solenoid valve on the frame to directly below the lifting cover. The blowing component is arranged inside the lifting cover and is used to blow air on the surface and inside the holes of the CDC solenoid valve located within the opening of the lifting cover.

[0007] By adopting the above technical solution, compared with the prior art, in which only by a worker holding the detected CDC solenoid valve in one hand and a blow gun in the other hand, and aligning the air outlet end of the blow gun with the surface and the inside of the holes of the CDC solenoid valve, can the residual oil stains on the surface and inside the holes of the CDC solenoid valve be blown out, thus greatly reducing the oil removal efficiency of the CDC solenoid valve; in this application, by setting up the oil removal mechanism, after the conveying mechanism conveys the CDC solenoid valve to directly below the lifting cover, the lifting component can drive the lifting cover to descend, so as to cover the CDC solenoid valve, and enable the air blowing component in the lifting cover to blow air on the surface and inside the holes of the CDC solenoid valve, thereby blowing the oil stains on the surface and inside the holes of the CDC solenoid valve out of the CDC solenoid valve, and then realizing the oil removal of the CDC solenoid valve, effectively facilitating the operation of the worker, and further improving the oil removal efficiency of the CDC solenoid valve.

[0008] Preferably, a positioning mechanism is further arranged on the frame. The positioning mechanism includes a stop frame and a moving component, and the stop frame is located on the displacement path of the CDC solenoid valve driven by the conveying mechanism. The moving component is used to drive the stop frame to displace, so that the stop frame disengages from the CDC solenoid valve.

[0009] By adopting the above technical solution, the setting of the positioning mechanism enables the stop frame to abut against the CDC solenoid valve after the CDC solenoid valve moves to directly below the lifting cover, thereby hindering the further movement of the CDC solenoid valve, keeping the CDC solenoid valve in the state directly below the lifting cover, and then realizing the positioning effect on the CDC solenoid valve in the moving direction, effectively ensuring that the CDC solenoid valve can smoothly enter the lifting cover, and further ensuring the smooth operation of this application.

[0010] Preferably, the stop frame includes a main body frame and an abutting frame. The main body frame is arranged on the frame. The abutting frame is located on the displacement path of the CDC solenoid valve and is slidably connected to the main body frame. The moving component is used to drive the abutting frame to slide, so that the abutting frame releases the abutment with the CDC solenoid valve.

[0011] By adopting the above technical solution, the specific setting of the stop frame enables the moving component to drive the abutting frame to slide relative to the main body frame when it is necessary to release the restriction of the abutting frame on the CDC solenoid valve, so that the abutting frame is no longer located on the displacement path of the CDC solenoid valve, releases the restriction on the CDC solenoid valve, and enables the oil-removed CDC solenoid valve to continue to move, thus ensuring the smooth output of the CDC solenoid valve.

[0012] Preferably, the number of the stop brackets is set to two, and they are respectively located on the opposite sides of the CDC solenoid valve. The positioning mechanism further includes a positioning frame and a linkage assembly. The number of the positioning frames is set to several, and they are respectively located on the opposite sides of the CDC solenoid valve. Each positioning frame is rotatably connected to the frame, and the main body frame drives each positioning frame to rotate through the linkage assembly.

[0013] By adopting the above technical solution, the setting of the positioning component enables the main body frame to drive the positioning frame to rotate through the linkage assembly, so that the positioning frame clamps both sides of the CDC solenoid valve, and the CDC solenoid valve is clamped to the designated position, thereby realizing the positioning of the CDC solenoid valve in the direction other than its own displacement direction, increasing the positioning effect of the CDC solenoid valve, and further ensuring that the CDC solenoid valve can smoothly enter the lifting cover.

[0014] Preferably, each main body frame is slidably connected to the frame, and the sliding direction is the same as the conveying direction of the CDC solenoid valve. The linkage assembly includes several linkage frames, which correspond to the abutting frames. One end of each linkage frame is rotatably connected to the corresponding abutting frame, and the other end is rotatably connected to the corresponding positioning frame.

[0015] By adopting the above technical solution, the setting of the linkage assembly enables the main body frame to drive the linkage frame to displace when the CDC solenoid valve abuts against the abutting frame and thus pushes the abutting frame and the main body frame to slide together, and enables one end of the linkage frame to rotate relative to the main body frame, so that the other end of the linkage frame can drive the corresponding positioning frame to rotate, thereby realizing the driving of the rotation of the positioning frame, effectively realizing the linkage between the positioning frame and the main body frame, and thus replacing the active device for driving the rotation of the positioning frame, which facilitates the operation of the staff.

[0016] Preferably, the moving assembly includes a transmission frame, one end of which is rotatably connected to the abutting frame, and the other end is rotatably connected to the frame.

[0017] By adopting the above technical solution, the setting of the transmission frame enables one end of the transmission frame rotatably connected to the abutting frame to displace together with the abutting frame during the displacement of the abutting frame along with the main body frame, so that the other end of the abutting frame rotates relative to the frame, and further enables the transmission frame to drive the abutting frame to slide, thereby realizing the driving of the sliding of the abutting frame, effectively realizing the linkage between the abutting frame and the main body frame, and facilitating the operation of the staff.

[0018] Preferably, a tray is further provided on the rack, the CDC solenoid valve is arranged on the tray, the conveying mechanism is used for conveying the tray, and the positioning mechanism further includes a lifting assembly for lifting the tray directly below the lifting cover.

[0019] By adopting the above technical solution, the arrangement of the tray and the lifting assembly enables the lifting assembly to drive the tray to move upward, thereby causing the tray and the CDC solenoid valve to be lifted upward, so as to disengage from the rack, allowing the lifting cover to smoothly cover the CDC solenoid valve, and thus reducing the probability of interference between the rack and the lifting cover, ensuring the oil removal effect on the CDC solenoid valve.

[0020] Preferably, the air blowing assembly includes a first air blowing nozzle and a plurality of second air blowing nozzles. The first air blowing nozzle and each second air blowing nozzle are arranged on the top of the lifting cover. The bottom of the first air blowing nozzle extends into the hole of the CDC solenoid valve directly below the lifting cover, and the bottom of each second air blowing nozzle faces different parts of the surface of the CDC solenoid valve. The first air blowing nozzle and each second air blowing nozzle are connected to a gas source.

[0021] By adopting the above technical solution, the arrangement of the air blowing assembly enables the first air blowing nozzle and the second air blowing nozzles to blow air into the hole and on the surface of the CDC solenoid valve, so as to blow the oil stains inside and on the surface of the CDC solenoid valve out of the CDC solenoid valve, effectively ensuring the oil removal effect on the CDC solenoid valve.

[0022] Preferably, the air outlet end of each second air blowing nozzle is connected to an air blowing flexible pipe, and each air blowing flexible pipe extends downward and is close to the surface of the CDC solenoid valve.

[0023] By adopting the above technical solution, the arrangement of the air blowing flexible pipe enables the staff to adjust the orientation and specific shape of the air blowing flexible pipe according to the size and model of the CDC solenoid valve before blowing oil off the CDC solenoid valve, so that the air blowing end of the air blowing flexible pipe can smoothly blow air on the oil stains at different parts of the CDC solenoid valve, effectively ensuring the air blowing effect on the CDC solenoid valve.

[0024] Preferably, an oil mist collecting pipe is further provided on the lifting cover. One end of the oil mist collecting pipe is communicated with the chamber inside the lifting cover, and the other end is used for communicating with a device for treating oil stains.

[0025] By adopting the above technical solution, the arrangement of the oil mist collection pipe enables the oil stains on the surface of the CDC solenoid valve to turn into a mist state after blowing air, and then can be discharged through the oil mist collection pipe, thereby reducing the probability that the formed oil mist stays in the lifting cover continuously, further ensuring the cleanliness of the lifting cover, and facilitating the subsequent cleaning of the lifting cover by the staff.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: The arrangement of the oil removal mechanism enables the lifting component to drive the lifting cover to descend after the conveying mechanism transports the CDC solenoid valve to directly below the lifting cover, so as to cover the CDC solenoid valve, and enables the blowing component in the lifting cover to blow air on the surface and inside the holes of the CDC solenoid valve, thereby blowing the oil stains on the surface and inside the holes of the CDC solenoid valve outside the CDC solenoid valve, and further realizing the oil removal of the CDC solenoid valve, effectively facilitating the operation of the staff, and further improving the oil removal efficiency of the CDC solenoid valve; The arrangement of the positioning mechanism enables the stop frame to abut against the CDC solenoid valve when the CDC solenoid valve moves to directly below the lifting cover, thereby hindering the further movement of the CDC solenoid valve, keeping the CDC solenoid valve in the state directly below the lifting cover, and further realizing the positioning function of the CDC solenoid valve in the moving direction, effectively ensuring that the CDC solenoid valve can smoothly enter the lifting cover, and further ensuring the smooth operation of the present application; The arrangement of the blowing coiled pipe enables the staff to adjust the orientation and specific shape of the blowing coiled pipe according to the size and model of the CDC solenoid valve before blowing air to remove oil from the CDC solenoid valve, so that the blowing end of the blowing coiled pipe can smoothly blow air on the oil stains at different parts of the CDC solenoid valve, and further effectively ensuring the blowing effect on the CDC solenoid valve.

Detailed implementation manners

[0034] The following further elaborates on the present application in conjunction with the attached Figures 1-6 drawings. Embodiment 1:

[0035] Embodiment 1 of the present application discloses a degreasing device for CDC valve testing. Referring to Figure 1 and Figure 2 , the degreasing device for CDC valve testing includes a frame 1, and a conveying mechanism 2 and a degreasing mechanism 3 are further arranged on the frame 1. The degreasing mechanism 3 includes a lifting cover 31, a lifting assembly 32 and a blowing assembly 33. The bottom of the lifting cover 31 is provided with an opening, and the lifting assembly 32 is used to drive the lifting cover 31 to lift and lower. The conveying mechanism 2 is used to convey the CDC solenoid valve on the frame 1 to directly below the lifting cover 31, and the blowing assembly 33 is arranged inside the lifting cover 31 and is used to blow the surface and the inside of the holes of the CDC solenoid valve 10 located inside the opening of the lifting cover 31.

[0036] Referring to Figure 1 , one end of the frame 1 extends outwards to extend to the performance detection station, so that the CDC solenoid valve after being detected at the performance detection station can be placed on the frame 1 and can be moved to the degreasing station (i.e., directly below the lifting cover 31) under the drive of the conveying mechanism 2.

[0037] Referring to Figure 1 and Figure 3, a plurality of trays 4 and a plurality of placement fixtures 5 are further provided on the frame 1, and the trays 4 and the placement fixtures 5 are arranged in one-to-one correspondence. An opening is formed through the center of the top of each of the tray 4 and the placement fixture 5. Each placement fixture 5 is supported by a cylinder at the top of the corresponding tray 4, so that a space is formed between the bottom of the placement fixture 5 and the bottom wall of the tray 4. After each inspection, the CDC solenoid valve 10 to be degreased is placed in the opening of the corresponding placement fixture 5, and the bottom of each CDC solenoid valve 10 abuts against the top of the placement fixture 5 to achieve its own support and enable the bottom of itself to extend to the lower side of the placement fixture 5.

[0038] Refer to Figure 1 and Figure 3 , each tray 4 is slidably connected to the frame 1 through a slide rail, and the sliding direction is the length direction of the frame 1. The conveying mechanism 2 includes a conveyor belt 21 and a plurality of frames 22. The conveyor belt 21 is installed on the frame 1, and the conveying direction is the extending direction of the frame 1, and the conveyor belt 21 is located on one side of the width direction of the frame 1. The plurality of frames 22 are fixedly installed on the conveyor belt 21 and are evenly distributed at equal intervals along the conveying direction of the conveyor belt 21. The side wall of each frame 22 abuts against the side wall of the adjacent tray 4 to drive the sliding of the tray 4, so as to realize the conveying of the tray 4.

[0039] Refer to Figure 1 , in other embodiments, the conveyor belt 21 in the conveying mechanism 2 can also be replaced by a combined structure of a chain, a sprocket and a motor, so that the chain drives the frame 22 to move, ensuring the installation stability of the frame 22.

[0040] Refer to Figure 1 and Figure 3 , a wire winding column 51 and a plurality of wire winding frames 52 are further provided on the top of the placement fixture 5. The wire winding column 51 and each wire winding frame 52 are fixedly installed on the top of the placement fixture 5 through bolts, and the CDC solenoid valve 10 on the placement fixture 5 is located between the wire winding column 51 and the plurality of wire winding frames 52. The wire winding column 51 is located on one side of the CDC solenoid valve 10, and the plurality of wire winding frames 52 are circumferentially and equally angularly distributed along the axis of the placement fixture 5.

[0041] Refer to Figure 3, a plug-in rack 53 is further provided on the top of the placement tooling 5. The plug-in rack 53 is fixedly connected to the bottom of the placement tooling 5 by bolts. An opening is further formed at the side end of the plug-in rack 53, so that the interface at the end of the wire of the CDC solenoid valve 10 can be inserted into the opening of the plug-in rack 53. Thus, when the staff places the CDC solenoid valve 10 on the placement tooling 5, the middle part of the wire (the wire is not fully drawn) of the CDC solenoid valve 10 can be wound around the wire-winding column 51, the tail of the wire can be wound around each wire-winding rack 52, and the end interface of the wire can be inserted into the opening of the plug-in rack 53, thereby reducing the adverse effect of the wire of the CDC solenoid valve 10 on subsequent degreasing.

[0042] Referring to Figure 1 and Figure 4 , a positioning mechanism 6 is further provided on the frame 1. The positioning mechanism 6 includes a stop rack 61 and a moving component 62. The stop rack 61 is located below the lifting cover 31 and on the displacement path of the tray 4. Thus, when the tray 4 moves to directly below the lifting cover 31, the stop rack 61 can abut against the tray 4, so that the moving component 62 is used to drive the stop rack 61 to displace, so that the stop rack 61 disengages from the CDC solenoid valve 10.

[0043] Referring to Figure 1 and Figure 4 , the moving component 62 includes a moving member 621. In the embodiment of the present application, the moving member 621 is set as a cylinder. The cylinder is fixedly installed on the frame 1, the piston rod is arranged vertically upward, and the end of the piston rod is fixedly connected to the top of the stop rack 61, so as to drive the stop rack 61 to displace in the vertical direction, thereby controlling whether the stop rack 61 abuts against the tray 4.

[0044] Referring to Figure 1 and Figure 4 , a lifting component 7 is further provided at the bottom of the frame 1. The lifting component 7 includes a lifting frame 71 and a lifting cylinder 72. The lifting cylinder 72 is fixedly installed on the frame 1, the piston rod is arranged vertically upward, and is fixedly connected to the bottom of the lifting frame 71. A plurality of top push rods 711 further extend upward from the top of the lifting frame 71. The top push part is fixedly connected to the lifting frame 71 and corresponds to the holes on the tray 4. The diameter of the top of the top push rod 711 is smaller than the diameter of the rest part, so that the top push rod 711 can push the tray 4 to move upward after being inserted into the hole.

[0045] Referring to Figure 4 , a hole is further formed at the top of the lifting frame 71 for the oil stain flowing out of the central hole of the CDC solenoid valve 10 to pass through. One end of the hole extends downward and finally extends to the side wall of the lifting frame 71 and communicates with the outside. In the embodiment of the present application, a pipeline can be further provided on the side wall of the lifting frame 71 for the oil stain passing through the above hole to pass through.

[0046] Reference Figure 1 and Figure 2 Figure 2 , the lifting cover 31 is slidably connected to the frame 1 through a plurality of guide rods, and the sliding direction is the vertical direction. In the embodiment of the present application, the lifting assembly 32 is set as a cylinder, which is fixedly installed on the top of the frame 1, and the piston rod is vertically downward and fixedly connected to the top of the lifting cover 31 to drive the lifting cover 31 to slide.

[0047] Reference Figure 2 Figure 2 , a sleeve cover 8 is further arranged in the lifting cover 31. The sleeve cover 8 is fixedly installed on the inner top wall of the lifting cover 31 and has an open bottom end. The air blowing assembly 33 includes a first air blowing nozzle 331 and a plurality of second air blowing nozzles 332. The first air blowing nozzle 331 is fixedly installed at the inner top end of the sleeve cover 8, and the bottom end of the first air blowing nozzle 331 is open, so as to cover the top end of the central hole of the CDC solenoid valve 10 after the CDC solenoid valve 10 is lifted, so that the sleeve cover 8 can reduce the external discharge of the air flow of the first air blowing nozzle 331 and ensure the air blowing effect on the central hole of the CDC solenoid valve 10. A hose is further arranged on the top of the first air blowing nozzle 331 for connecting to a gas source.

[0048] Reference Figure 2 Figure 2 , the first air blowing nozzle 331 is arranged directly above the central hole of the CDC solenoid valve 10, and the jet end is vertically downward for blowing towards the central hole of the CDC solenoid valve 10. Each second air blowing nozzle 332 is fixedly installed on the inner top wall of the lifting cover 31, and the bottom end of each second air blowing nozzle 332 is vertically downward for blowing towards the surface of the CDC solenoid valve 10. The top of each second air blowing nozzle 332 extends to the top of the lifting cover 31 to facilitate connecting the hose, so that the gas source enters the second air blowing nozzle 332.

[0049] Reference Figure 2 Figure 2 , each second air blowing nozzle 332 is circumferentially distributed along the axis of the sleeve cover 8, so that the bottom end of the second air blowing nozzle 332 faces different positions of the CDC solenoid valve 10. Two air blowing serpentine pipes 3321 are arranged at the bottom of each second air blowing nozzle 332. The top of each air blowing serpentine pipe 3321 is connected to the corresponding second air blowing nozzle 332, and the bottom end extends downward for approaching the surface of the CDC solenoid valve 10. Before degreasing, the air blowing serpentine pipe 3321 can be adjusted by the staff to face any position and maintain this state, so as to facilitate subsequent air blowing on the surface of the CDC solenoid valve 10.

[0050] Reference Figure 2An oil mist collecting pipe 9 is also provided on the side wall of the lifting cover 31. One end of the oil mist collecting pipe 9 is connected to the chamber in the lifting cover 31, and the other end is bent upward and used to connect to the device for processing oil mist, so as to discharge the mist oil generated in the air blowing and oil removal process.

[0051] The implementation principle of the degreasing device for testing a CDC valve in Example 1 of the present application is as follows: when in use, when the conveying mechanism 2 conveys the tray 4 to the bottom of the lifting cover 31, the tray 4 abuts against the stop frame 61, thereby positioning the tray 4. Thereafter, the lifting cylinder 72 drives the lifting frame 71 to move upward, so that the lifting frame 71 drives the tray 4 to rise and thus detach from the frame 1. Then, the lifting assembly 32 drives the lifting cover 31 to move downward, so that the CDC solenoid valve 10 enters the lifting cover 31 through the opening at the bottom of the lifting cover 31. At this time, the sleeve cover 8 is sleeved on the top of the CDC solenoid valve 10. Thereafter, the first air blowing nozzle 331 and the second air blowing nozzle 332 blow air to the inside of the hole and the surface of the CDC solenoid valve 10, so that the oil stains on the CDC solenoid valve 10 are blown away. Embodiment 2:

[0052] The difference between the second embodiment of the present application and the first embodiment is that: Figure 5 and Figure 6 The number of the stop frame 61 and the moving assembly 62 is set to two, and they are arranged one by one. The two stop frames 61 are respectively located on both sides of the frame 1 along its width direction. Each stop frame 61 includes a main frame 611 and an abutment frame 612. Each main frame 611 is slidably connected to the frame 1 through a slide rail, and the sliding direction is the length direction of the frame 1.

[0053] Reference Figure 5 and Figure 6 Each abutting frame 612 is located on a side of the corresponding main frame 611 close to another main frame 611, and is sleeved on the corresponding main frame 611, and is slidably connected to the corresponding main frame 611, and the sliding direction is the library width direction of the rack 1. The end of each abutting frame 612 away from the corresponding main frame 611 is located on the displacement path of the corresponding tray 4, so that it can pass through and abut against the side wall of the tray 4.

[0054] Reference Figure 5 and Figure 6 A return spring 63 is sleeved on one end of each main frame 611 in the opposite direction of the conveying direction of the tray 4. One end of each return spring 63 abuts against the corresponding main frame 611, and the other end abuts against the frame 1, so as to reset the corresponding main frame 611 through its own elastic force.

[0055] Reference Figure 5 and Figure 6, each moving component 62 includes a transmission frame 622. One end of each transmission frame 622 is rotatably connected to the corresponding abutting frame 612 through a pin shaft, and the other end is inclined towards the direction close to the other transmission frame 622 and is rotatably connected to the machine frame 1 through a pin shaft.

[0056] Refer to Figure 5 and Figure 6 , the positioning mechanism 6 further includes two retaining components 64, and the retaining components 64 are arranged in one-to-one correspondence with the main body frame 611. Each retaining component 64 includes a retaining frame 641 and a moving cylinder 642. Each moving cylinder 642 is fixedly installed on the machine frame 1, and the piston rod is arranged vertically upward and is fixedly connected to the bottom end of the corresponding retaining frame 641 to drive the retaining frame 641 to move up and down. Each retaining frame 641 is located on one side of the corresponding main body frame 611 in the opposite direction of the conveying direction of the tray 4, and abuts against the side wall of the corresponding main body frame 611 to limit the sliding of the main body frame 611 by abutting.

[0057] Refer to Figure 5 and Figure 6 , in the initial state, at this time the tray 4 has not moved to directly below the lifting cover 31, at this time the tray 4 does not abut against the abutting frame 612, and at this time the retaining frame 641 abuts against the side wall of the main body frame 611. When the tray 4 abuts against the abutting frame 612, the tray 4 drives the abutting frame 612 and the main body frame 611 to slide, and at this time the return spring 63 is compressed. When the tray 4 moves to directly below the lifting cover 31, the main body frame 611 abuts against the retaining frame 641, thereby positioning the tray 4.

[0058] Refer to Figure 5 and Figure 6 , during this process, one end of the transmission frame 622 rotates relative to the machine frame 1, so that the other end of the transmission frame 622 drives the abutting frame 612 to slide relative to the main body frame 611. When the defatting of the CDC solenoid valve 10 on the tray 4 is completed and the tray 4 descends to the initial position again, the moving cylinder 642 drives the retaining frame 641 to move downward, so that the retaining frame 641 releases the limit on the main body frame 611.

[0059] Refer to Figure 5 and Figure 6 , after that, the conveying mechanism 2 drives the tray 4 to continue to displace, so that the tray 4 drives the positioning frame 65 to continue to slide through the abutting frame 612. During this process, one end of the transmission frame 622 rotates relative to the machine frame 1, so that the other end of the transmission frame 622 drives the abutting frame 612 to slide relative to the main body frame 611. When the abutting frame 612 disengages from the side wall of the tray 4 that it abuts against, the abutting frame 612 releases the limit on the tray 4, so that the tray 4 can displace independently.

[0060] Refer toFigure 5 and Figure 6 During this process, the abutting frame 612 and the body frame 611 maintain their current positions, and the abutting frame 612 abuts against the other side wall of the tray 4. When the tray 4 moves away from the abutting frame 612, the body frame 611 returns to its initial position under the elastic force of the return spring 63. During this process, the abutting frame 612 is also driven by the transmission frame 622 and returns to its initial position.

[0061] Referring to Figure 5 and Figure 6 As shown in FIGS. and, the positioning mechanism 6 further includes two positioning frames 65 and a linkage assembly 66. The positioning frames 65 are arranged in one-to-one correspondence with the body frames 611. Each positioning frame 65 is located on the side of the corresponding body frame 611 away from the transmission frame 622. One end of each positioning frame 65 is rotatably connected to the frame 1, and a buffer frame 67 is provided on the side where the other ends of each positioning frame 65 are close to each other. In other embodiments, rollers may also be provided on the side of the buffer frame 67 close to the tray 4 to reduce the friction between the buffer frame 67 and the side wall of the tray 4.

[0062] Referring to Figure 5 and Figure 6 As shown in FIGS. and, each buffer frame 67 is slidably connected to the corresponding positioning frame 65, and the sliding direction is the width direction of the corresponding positioning frame 65. A buffer spring 68 is sleeved on each buffer frame 67. Each buffer spring 68 is located between the buffer frame 67 and the corresponding body frame 611, and one end abuts against the corresponding buffer frame 67 and the other end abuts against the corresponding body frame 611.

[0063] Referring to Figure 5 and Figure 6 As shown in FIGS. and, the linkage assembly 66 includes two linkage frames 661. The linkage frames 661 are arranged in one-to-one correspondence with the positioning frames 65. One end of each linkage frame 661 is rotatably connected to the corresponding positioning frame 65 through a pin shaft, and the other end is rotatably connected to the corresponding body frame 611 through a pin shaft.

[0064] Referring to Figure 5 and Figure 6 In the initial state, the tray 4 has not moved directly below the lifting cover 31, and at this time, the buffer frame 67 does not abut against the side wall of the tray 4. When the tray 4 abuts against the abutting frame 612, the abutting frame 612 drives the body frame 611 to slide, so that the body frame 611 drives the positioning frame 65 to rotate through the linkage frame 661, so that the buffer frame 67 gradually approaches the side wall of the tray 4. When the body frame 611 abuts against the retaining frame 641, the buffer frame 67 abuts against the side wall of the tray 4.

[0065] Referring to Figure 5 and Figure 6, when the degreasing of the CDC solenoid valve 10 on the tray 4 is completed and the tray 4 descends back to the initial position, the moving cylinder 642 drives the retaining frame 641 to move downward, so that the retaining frame 641 releases the limit on the body frame 611. After that, the tray 4 drives the body frame 611 to continue sliding, so that the positioning frame 65 continues to rotate. During this process, the buffer frame 67 slides relative to the positioning frame 65.

[0066] The implementation principle of the degreasing device for CDC valve testing in Embodiment 2 of the present application is as follows: when the tray 4 abuts against the abutting frame 612, the tray 4 drives the abutting frame 612 to slide with the body frame 611, and at this time the return spring 63 is compressed. During this process, one end of the transmission frame 622 rotates relative to the frame 1, so that the other end of the transmission frame 622 drives the abutting frame 612 to slide relative to the body frame 611. During this process, the body frame 611 drives the positioning frame 65 to rotate through the linkage frame 661, so that the buffer frame 67 gradually approaches the side wall of the tray 4.

[0067] When the tray 4 moves to directly below the lifting cover 31, the body frame 611 abuts against the retaining frame 641, and the buffer frame 67 abuts against the side wall of the tray 4, so that the buffer frame 67 and the abutting frame 612 position the tray 4 in the length and width directions of the frame 1, ensuring the position accuracy of the CDC solenoid valve 10.

[0068] , when the degreasing of the CDC solenoid valve 10 on the tray 4 is completed and the tray 4 descends back to the initial position, the moving cylinder 642 drives the retaining frame 641 to move downward, so that the retaining frame 641 releases the limit on the body frame 611. After that, the tray 4 drives the body frame 611 to continue sliding, so that the positioning frame 65 continues to rotate. During this process, the buffer frame 67 slides relative to the positioning frame 65.

[0069] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
