It includes a power unit that provides power to complete the tightening and pressing actions, a testing device that ensures assembly accuracy and quality, and an automated control system that controls the entire assembly process. Its purpose is to complete the assembly of the DRV valve efficiently and with high quality through precise operation and a reasonable process, ensuring that the DRV valve meets design requirements and performance requirements.

[0003] A search revealed Chinese Patent Publication No. CN211900839U, which discloses a normally open DRV pressure control valve, comprising a housing, a valve sleeve at the bottom of the housing, a push rod at the middle of the housing, a steel ball between the push rod and the valve sleeve, a filter screen at the bottom of the valve sleeve, a coil assembly at the middle of the interior of the housing, a power inlet on one side of the top of the coil assembly, an annular groove adapted to the coil assembly inside the housing, the coil assembly being detachably connected to the annular groove, and an armature at the top of the housing. By setting an armature and valve cover that are compatible with the coil assembly, and by setting a protruding rib at the lower end of the valve cover that contacts the armature, the effective air gap of the product is significantly increased, and the electromagnetic force of the pressure control valve is greatly improved. Furthermore, through pressure curve performance testing and comparison, it is verified that the performance curve of the modified parts fully meets the requirements. However, in the existing DRV valve assembly mechanism, the valve sleeve installed on the DRV valve housing is installed manually by workers. This process involves pressing the valve sleeve into the housing with force, which requires a lot of force and is therefore very inconvenient to install, resulting in reduced production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a DRV valve assembly mechanism, which aims to improve the problem that the existing technology, which requires a lot of force to complete the installation, is very inconvenient to install and leads to reduced production efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a DRV valve assembly mechanism, including a base, an electric push rod fixedly connected to the middle of the top wall of the base, a movable plate fixedly connected to the output end of the electric push rod, two fixing blocks fixedly connected to the top left and right sides of the movable plate, a support rod fixedly connected to the top rear side of the base, a hydraulic push rod fixedly connected to the top of the outer wall of the support rod, a fixing plate fixedly connected to the output end of the hydraulic push rod, pressing blocks fixedly connected to the bottom left and right sides of the fixing plate, the pressing blocks engaging with the two fixing blocks, fixing columns fixedly connected to the top left and right sides of the base, adjusting columns slidably connected to the top of the outer walls of the two fixing columns, a probe slidably connected to one side of the outer wall of the adjusting column, and a clamping mechanism fixedly connected to the top of the outer wall of the base, the clamping mechanism being used to clamp different types of valve sleeves.

[0009] Through the above technical solution: the fixing block 1 is fixed to the top of the outer wall of the base, supporting the clamping mechanism. The external force drives the gear to rotate. Through the gear transmission principle, the racks on both sides move in opposite linear directions, and the fixing clamp 1 moves synchronously to initially clamp the object. The connecting plate 1 connects the clamp spring and the adjusting plate 1. After the initial clamping, the clamp spring deforms elastically, the adjusting plate 1 moves, and the fixing clamp 2 applies additional clamping force, working together with the fixing clamp 1 to ensure that the object is stable during the assembly of the DRV valve and to ensure assembly accuracy.

[0010] As a further description of the above technical solution:

[0014] The base has handles fixedly connected to the top left and right sides, and the handles have fixing holes on the front and back sides of their inner walls.

[0015] The above technical solution provides handles on both sides of the top of the base, which facilitates the operator's handling of the device. The fixing holes in the handles can be connected to auxiliary devices to stabilize the device under certain circumstances, prevent operational displacement, and ensure smooth assembly of the DRV valve.

[0016] As a further description of the above technical solution:

[0017] A support frame is fixedly connected to the top front side of the base, and a detection mechanism is fixedly connected to the top of the outer wall of the support frame.

[0018] The above technical solution involves a support frame fixedly connected to the top front of the base to provide stability for the device, and a detection mechanism fixed to the top of the outer wall to accurately detect and measure the valve sleeve, ensuring quality standards.

[0021] Through the above technical solution, the moving plate is fixed to the left and right sides of the bottom wall through sliding cooperation with the slider and slide bar, ensuring stable linear movement under the drive of the electric push rod.

[0022] As a further description of the above technical solution:

[0023] Gaskets are fixedly connected to the top left and right sides of the fixing plate, and connection holes are provided at the four corners of the outer wall of the gaskets.

[0024] The above technical solution uses gaskets and connecting holes on the top left and right sides of the fixed plate to facilitate the secure connection of other components and enhance the overall structural integrity.

[0025] As a further description of the above technical solution:

[0026] The top left and right sides of the support rod are fixedly connected to the support frame two, and the middle of the inner wall of the support frame two is fixedly connected to the positioning mechanism.

The pressing block can accurately engage the fixing block 2 on the moving plate under the push of the hydraulic push rod, thus ensuring the accuracy of the DRV valve assembly operation.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the electric push rod is installed in the middle of the top wall of the base and connected to the moving plate. The hydraulic push rod is located at the top of the support rod and connected to the fixed plate. After starting, it is pushed to move, and the moving plate and the second fixed block move to the assembly position. The hydraulic push rod starts to move the fixed plate downward, and the pressing block moves and engages with the second fixed block to fix the DRV valve components, ensuring assembly stability and accuracy.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a DRV valve assembly mechanism, including a base 1, an electric push rod 3 fixedly connected to the middle of the top wall of the base 1, a movable plate 4 fixedly connected to the output end of the electric push rod 3, two fixed blocks 5 fixedly connected to the top left and right sides of the movable plate 4, a support rod 6 fixedly connected to the top rear side of the base 1, a hydraulic push rod 7 fixedly connected to the top of the outer wall of the support rod 6, a fixed plate 8 fixedly connected to the output end of the hydraulic push rod 7, a pressing block 9 fixedly connected to the bottom left and right sides of the fixed plate 8, the pressing block 9 engaging with the two fixed blocks 5, a fixed column 10 fixedly connected to the top left and right sides of the base 1, an adjusting column 11 slidably connected to the top of the outer wall of the two fixed columns 10, a probe 12 slidably connected to one side of the outer wall of the adjusting column 11, a clamping mechanism 2 fixedly connected to the top of the outer wall of the base 1, the clamping mechanism 2 being used to clamp different types of valve sleeves, a support frame 17 fixedly connected to the top front side of the base 1, and a detection mechanism 18 fixedly connected to the top of the outer wall of the support frame 17.

[0040] Specifically, the electric push rod 3 is installed in the middle of the top wall of the base 1 and connected to the movable plate 4. When started, it is pushed to move linearly. The hydraulic push rod 7 is located at the top of the support rod 6 and connected to the fixed plate 8. After starting, it is pushed to move, and the movable plate 4 and the second fixed block 5 move to the assembly position. When the hydraulic push rod 7 is started, the fixed plate 8 moves downward, and the pressing block 9 moves accordingly and engages with the second fixed block 5 to fix the DRV valve components, ensuring assembly stability and accuracy. The fixed column 10 is fixed on both sides of the base 1, and the adjusting column 11 can slide to adjust the vertical position to adapt to different DRV valve assembly requirements. The probe 12 is on the outer wall of the adjusting column 11. After sliding to the detection position, the DRV valve is inspected, such as the position of components and the assembly status. A clamping mechanism 2 is fixedly connected to the top of the base 1. This clamping mechanism 2 is used to clamp valve sleeves of various types and sizes to ensure that they can be stably fixed in the appropriate position. A support frame 17 is fixedly connected to the front top of the base 1. This support frame 17 not only provides additional stability to the entire device, but also has a detection mechanism 18 fixedly connected to the top of its outer wall. The detection mechanism 18 is responsible for accurately detecting and measuring the valve sleeves to ensure that each valve sleeve meets the predetermined quality standards.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The clamping mechanism 2 includes a fixing block 201, which is fixedly connected to the top of the outer wall of the base 1. A gear 202 is rotatably connected to the middle of the inner wall of the fixing block 201. Racks 203 are slidably connected to the left and right sides of the inner wall of the fixing block 201. The gear 202 meshes with the racks 203. Fixing clamps 204 are fixedly connected to the top of the outer walls of the two racks 203. Connecting plates 205 are fixedly connected to the left and right sides of the inner wall of the fixing block 201. Clip springs 206 are fixedly connected to the left and right ends of the inner wall of 205. Adjustment plate 207 is fixedly connected to the top of the outer wall of clip spring 206. Fixing clip 208 is fixedly connected to the top of the outer wall of adjustment plate 207. Connecting plate 23 is rotatably connected to the front and rear sides of the outer wall of connecting plate 205. Adjustment plate 24 is rotatably connected to the other end of connecting plate 213. Handles 15 are fixedly connected to the top left and right sides of the base 1. Fixing holes 16 are opened on the front and rear sides of the inner wall of the handle 15.

[0042] Specifically, the fixing block 201 is fixed to the top of the outer wall of the base 1, providing support for the clamping mechanism 2. External force drives the gear 202 to rotate. Based on the gear and rack transmission principle, the gear 202 drives the two racks 203 meshing with it to move in opposite linear directions, causing the fixing clamp 204 fixed on the top of the racks 203 to move synchronously, achieving initial clamping of the object. The connecting plate 205 on the inner wall of the fixing block 201 connects the clamp spring 206 and the adjusting plate 207. After the fixing clamp 204 initially clamps the object, if the object size deviates or the clamping force needs to be finely adjusted, the clamp spring 206 deforms elastically, driving the adjusting plate 207 to move, thereby causing the fixing clamp 208 fixed on the top of the adjusting plate 207 to apply force to the object. The additional fine-tunable clamping force works in conjunction with the fixing clamp 204 to ensure the object is stable during DRV valve assembly and to guarantee assembly accuracy. The connecting plate 205, through its rotatable connection with the connecting plate 13, can change the angle of the connecting plate 13, thereby driving the adjusting plate 14, which is rotatably connected to it, to adjust its position and angle. This provides flexible adjustment function for the clamping mechanism 2 to adapt to DRV valve components of different shapes and positions. The handles 15 fixed on the top left and right sides of the base 1 make it convenient for operators to hold and carry the entire device. The fixing holes 16 opened on the inner wall of the handles 15 can be used to connect other auxiliary fixing devices to further stabilize the device in specific scenarios, prevent displacement during operation, and ensure the smooth progress of the DRV valve assembly process.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The bottom wall of the movable plate 4 is fixedly connected to the left and right sides of the slider 19, and the inner wall of the slider 19 is slidably connected to the slide strip 20. The top left and right sides of the fixed plate 8 are fixedly connected to the pad 21, and the four corners of the outer wall of the pad 21 are provided with connection holes 22. The top left and right sides of the support rod 6 are fixedly connected to the support frame 23, and the inner wall of the support frame 23 is fixedly connected to the positioning mechanism 24.

[0044] Specifically, the movable plate 4 relies on the sliding cooperation of the slider 19 and the slide bar 20 fixedly connected to the left and right sides of the bottom wall to ensure that the movable plate 4 moves stably in a straight line under the drive of the electric push rod 3; the gaskets 21 and their connecting holes 22 on the top left and right sides of the fixed plate 8 facilitate a stable connection with other components and enhance the overall structure; the positioning mechanism 24 connected to the support frame 23 on the top left and right sides of the support rod 6 is used to accurately determine the position of the hydraulic push rod 7 and the fixed plate 8, so that the extrusion block 9 can accurately engage with the fixed block 2 5 on the movable plate 4 under the push of the hydraulic push rod 7, ensuring that the DRV valve assembly operation is accurate.

[0045] Working principle: The electric push rod 3 is fixed to the middle of the top wall of the base 1, and its output end is connected to the moving plate 4. When the electric push rod 3 is started, its output end moves linearly, pushing the moving plate 4 to move in a straight line. The hydraulic push rod 7 is installed on the top of the outer wall of the support rod 6, and its output end is connected to the fixed plate 8. After the hydraulic push rod 7 is started, its output end pushes the fixed plate 8 to move. After the electric push rod 3 is started, it pushes the moving plate 4 to move, and the fixed blocks 5 on the left and right sides of the top of the moving plate 4 also move accordingly. During the movement, the fixed blocks 5 will reach the appropriate assembly position to prepare for the subsequent assembly operation. When the hydraulic push rod 7 is started, it pushes the fixed plate 8 to move downward, and the pressing blocks 9 on the left and right sides of the bottom of the fixed plate 8 also move downward. When the pressure block 9 moves to engage with the fixing block 2 5, it can fix the relevant components of the DRV valve, keeping these components stable during assembly, preventing displacement, and ensuring assembly accuracy. The fixing column 10 is fixed on the top left and right sides of the base 1. The adjusting column 11 can slide on the top of the outer wall of the fixing column 10. By sliding the adjusting column 11, its position in the vertical direction can be adjusted to meet the assembly requirements of DRV valves of different heights. The probe 12 can slide on one side of the outer wall of the adjusting column 11. After adjusting the position of the adjusting column 11, the probe 12 is slid to reach the appropriate detection position, thereby detecting the DRV valve, such as whether the position of the components is accurate, whether the assembly is in place, etc.

[0046] Fixed block 201 is fixed to the top of the outer wall of base 1, serving as the supporting foundation for the entire clamping mechanism 2. When an object needs to be clamped, external force is applied to gear 202 to make it rotate. Since gear 202 is meshed with rack 203, according to the gear 202 rack transmission principle, the rotation of gear 202 will drive the two meshed racks 203 to move in a straight line. Furthermore, due to the meshing relationship between gear 202 and the racks on both sides, the two racks 203 will move in opposite directions. Each rack 203 has a fixed clamp 204 fixedly connected to the top of its outer wall. Therefore, when the rack 203 moves linearly, the clamps 204 move synchronously with it. When an object needs to be clamped, the rotation of the gear 202 is controlled to move the two clamps 204 towards each other, thus clamping the object between them and achieving initial fixation. Connecting plates 205 are fixedly connected to the left and right sides of the inner wall of the fixing block 201. A clamp spring 206 and an adjusting plate 207 are connected to clamp 205. The clamp spring 206 is elastic and can generate elastic force. After the clamp 204 initially clamps the object, if there is a certain deviation in the size of the object or if the clamping force needs to be finely adjusted, the clamp spring 206 can adapt to the shape and size changes of the object through its own elastic deformation. At the same time, the adjusting plate 207 can be adjusted to a certain extent under the action of the clamp spring 206. The top of the outer wall of the adjusting plate 207 is fixedly connected to a clamp 208. The position adjustment of the adjusting plate 207 will drive the clamp 208 to move. Under the action of the clamp spring 206, the clamp 208 can apply an additional, finely adjustable clamping force to the object. Working together with the clamp 204, it further stabilizes the clamping of the object, improves the stability and adaptability of the clamping, and ensures that the clamped object remains fixed during the subsequent DRV valve assembly process, preventing displacement or shaking, thereby ensuring assembly accuracy.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
