Detailed implementation mode
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0019] Embodiment 1: This embodiment provides a high-pressure common rail pump test bench. Refer to Figures 1 - 6 Specifically, it includes a bottom plate 100. The bottom plate 100 is the basic support component of the test bench, bearing components such as the fixing plate 200 and the first turntable 103, and providing installation interfaces. Stable support is achieved through the L-shaped legs on the bottom surface to ensure the stability of the overall structure of the test bench. Above the bottom plate 100, there are fixing plates 200 distributed in parallel. The fixing plates 200 are the support carriers of the vibrating plate 300, providing sliding guidance for the jacking slide bars 203 through the rectangular sliding holes 202, and connecting with the bottom plate 100 through the fixing rods 201 to form a middle support structure. Between the bottom plate 100 and the fixing plate 200, there is a first turntable 103 distributed in suspension, and above the fixing plate 200, there is a vibrating plate 300 distributed in parallel. On the top surface of the fixing plate 200, four uniformly distributed rectangular sliding holes 202 are opened. The uniformly distributed rectangular sliding holes 202 ensure the parallelism of the movement of the jacking slide bars 203, avoiding the inclination of the vibrating plate 300. The fixing rods 201 enhance the connection strength between the fixing plate 200 and the bottom plate 100, improving the structural rigidity. Inside each rectangular sliding hole 202, a jacking slide bar 203 that penetrates is slidably inserted. The top end of each jacking slide bar 203 is fixedly connected to the bottom surface of the vibrating plate 300, and the bottom end of each jacking slide bar 203 is connected to the first turntable 103 through a jacking component. In the middle of the top surface of the vibrating plate 300, a fixed shaft 301 is rotatably inserted. At the top end of the fixed shaft 301, a second turntable 303 is fixedly provided. On the top surface of the second turntable 303, a high-pressure common rail pump 400 is placed, and the vibrating plate 300 is connected to the high-pressure common rail pump 400 through a clamping component.
[0020] Embodiment 2: On the basis of Embodiment 1, this embodiment further includes: In the specific implementation process, such as Figure 3 and Figure 5 As shown, L-shaped legs are fixedly provided at the four corners of the bottom surface of the bottom plate 100, fixing rods 201 are fixedly provided at the four corners of the bottom surface of the fixing plate 200, the bottom end of each fixing rod 201 is fixedly connected to the top surface of the bottom plate 100, four evenly distributed arc-shaped sliding seats 101 are fixedly provided on the top surface of the bottom plate 100, an arc-shaped sliding groove is provided on the inner arc surface of each arc-shaped sliding seat 101, the outer ring surface of the first turntable 103 is synchronously slidably engaged in the four arc-shaped sliding grooves, the arc-shaped sliding seat 101 is fixed to the top surface of the bottom plate 100, and the arc-shaped sliding groove inside it is engaged with the outer ring surface of the first turntable 103, restricting the movement track of the first turntable 103 to circular rotation. The arc-shaped sliding groove provides stable radial constraint, ensuring the concentricity when the first turntable 103 rotates and avoiding shaking; A square through hole is provided in the middle of the top surface of the bottom plate 100, a first motor 102 with an upward output end is installed inside the square through hole, the end of the motor shaft of the first motor 102 is fixedly connected to the middle of the first turntable 103, and the first motor 102 drives the first turntable 103 to rotate, providing a power source for the lifting assembly. By fixedly connecting the motor shaft to the first turntable 103, stable power transmission is achieved and the vibration frequency is controlled; The lifting assembly includes a trapezoidal top block 104 and a pulley 204. Four evenly distributed trapezoidal top blocks 104 are fixedly provided on the top surface of the first turntable 103. When the trapezoidal top block 104 rotates with the first turntable 103, its inclined surface pushes the pulley 204 to move up and down, driving the lifting slide rod 203 to reciprocate in the rectangular slide hole 202. The top end of the lifting slide rod 203 is fixedly connected to the vibration plate 300 to transmit the lifting force. A pulley 204 is installed at the bottom end of the lifting slide rod 203, and each pulley 204 slides against the corresponding trapezoidal top block 104. The pulley 204 converts sliding friction into rolling friction, reducing mechanical wear and improving the smoothness of movement. The inclined surface design of the trapezoidal top block 104 can adjust the lifting stroke to control the vibration amplitude; The first turntable 103 serves as the driving carrier of the lifting assembly. Through the cooperation of the trapezoidal top block 104 and the pulley 204, the rotational motion is converted into the reciprocating linear motion of the lifting slide rod 203. Through the engagement of the outer ring surface with the arc-shaped sliding groove, stable rotation around the axis of the first motor 102 is achieved. The evenly distributed trapezoidal top blocks 104 can drive the four lifting slide rods 203 to move synchronously, ensuring uniform force on the vibration plate 300.
[0021] Embodiment 3: On the basis of Embodiment 2, this embodiment further includes: In the specific implementation process, such as Figure 4 and Figure 6As shown, three evenly distributed rectangular slide seats 305 are fixed on the top surface of the vibration plate 300. The rectangular slide seats 305 are fixed to the vibration plate 300 to provide sliding guides for the rectangular slide bars 306. The limit pin shafts 307 are inserted into the oblique pin holes 304. When the second rotating disk 303 rotates, the rectangular slide bars 306 are driven to move radially through the inclined tracks of the pin holes. Each rectangular slide 305 is slidably inserted with a rectangular slide bar 306 that runs through it. The vibration plate 300 serves as a mounting carrier for the high-pressure common rail pump 400. The reciprocating vibration is achieved by the movement of the lifting slide bar 203. The rectangular slide 305 is used to mount the rectangular slide bar 306 and to fix the high-pressure common rail pump 400 with the clamping assembly. The parallel distribution structural design ensures that the vibration direction is vertical, avoiding the influence of lateral offset on the experimental accuracy. Three circularly distributed oblique pin holes 304 are provided on the top surface of the second rotating disk 303. A limiting pin shaft 307 is fixedly provided at the inner end of each rectangular sliding rod 306. Each limiting pin shaft 307 is slidably inserted in the corresponding oblique pin hole 304. The fixed shaft 301 passes through the vibration plate 300 and is fixedly connected to the second rotating disk 303 to transmit rotational power. The second rotating disk 303 is used to place the high-pressure common rail pump 400, and cooperates with the limiting pin shaft 307 through the oblique pin hole 304 to drive the rectangular sliding rod 306 to move. The inclination angle design of the oblique pin hole 304 generates a radial component force when the second rotating disk 303 rotates, automatically pushing the rectangular sliding rod 306 to slide inward to achieve a clamping function. The clamping assembly includes an F-type clamping plate 308. A vertically distributed F-type clamping plate 308 is fixed in the middle of each rectangular slide bar 306. The three F-type clamping plates 308 are distributed in a circle around the high-pressure common rail pump 400, and the top of each F-type clamping plate 308 is against the outer surface of the high-pressure common rail pump 400. The F-type clamping plate 308 is fixed in the middle of the rectangular slide bar 306, and the high-pressure common rail pump 400 is clamped or released as the slide bar moves. The three evenly distributed F-type clamping plates 308 form a three-point clamping to ensure that the high-pressure common rail pump 400 is firmly fixed and evenly stressed. The automatic clamping design simplifies the operation process and improves the experimental efficiency. A concentrically fixed large-diameter pulley 302 is sleeved in the middle of the fixed shaft 301, a rectangular frame is fixed on the right side of the vibration plate 300, a second motor 309 with an output end facing upward is installed inside the rectangular frame, a concentrically fixed small-diameter pulley 310 is sleeved on the motor shaft end of the second motor 309, the small-diameter pulley 310 is connected to the large-diameter pulley 302 through a driving belt 311, the second motor 309 drives the small-diameter pulley 310 to rotate, and the large-diameter pulley 302 and the fixed shaft 301 are driven to rotate through the driving belt 311, so as to realize the rotation of the second rotating disk 303, and the belt transmission structure has a buffering and vibration absorbing effect, avoiding the impact of rigid transmission on the clamping mechanism. The speed ratio design of the large and small diameter pulleys can amplify the torque and ensure the stability of the clamping force.
[0022] Specifically, the working principle and operation method of the present invention are as follows: Step 1: Place the high-pressure common rail pump 400 in the center on the second turntable 303. Driven by the second motor 309, the motor shaft of the second motor 309 drives the small-diameter pulley 310 to rotate synchronously. The small-diameter pulley 310 drives the large-diameter pulley 302, the fixed shaft 301 and the second turntable 303 to rotate through the drive belt 311; Step 2: When the second turntable 303 rotates, the oblique pin holes 304 on the second turntable 303 and the limit pin shaft 307 form a limiting effect, driving the rectangular slide bar 306 to slide inward along the rectangular slide seat 305, and driving the three F-shaped clamping plates 308 to abut against the outer surface of the high-pressure common rail pump 400, forming clamping and fixing of the high-pressure common rail pump 400, and then stop the operation of the second motor 309; Step 3: Driven by the first motor 102, the motor shaft of the first motor 102 drives the first turntable 103 to rotate along the arc-shaped chute on the arc-shaped slide seat 101. The trapezoidal top block 104 on the first turntable 103 and the pulley 204 form a limiting effect, driving the lifting slide bar 203 to slide reciprocally upward in the rectangular slide hole 202, synchronously driving the vibration plate 300, the second turntable 303 and the high-pressure common rail pump 400 to vibrate reciprocally, and then performing an impact-resistant vibration test on the high-pressure common rail pump 400.
