Description

Technical Field

[0001] The invention relates to the technical field of shock absorber testing equipment, and in particular to a high and low temperature integrated box for shock absorber durability specimens. Background Art

[0002] Shock absorbers are devices used to accelerate the attenuation of frame and body vibrations to improve the ride smoothness (comfort) of the car. Shock absorbers are installed in the suspension systems of most cars. Shock absorbers are important parts of cars, so they need to undergo durability tests. Traditional testing methods mostly use single-station test modes, and widely used cooling methods include using fans for air convection heat dissipation, using air amplifiers to increase air flow speed, and using water jacket cooling systems in some cases.

[0003] Although fans and air amplifiers can accelerate heat dissipation by increasing air flow, the relatively low thermal conductivity efficiency of air results in a slow cooling rate, especially when dealing with shock absorber bearings at high temperatures, the effect is particularly unobvious, thus prolonging the test cycle.

[0004] On the other hand, although the water jacket cooling system has high heat conduction efficiency and can quickly reduce the temperature of the sample, its design is complex, maintenance costs are high, and strict control of water temperature, flow and other parameters are required to avoid thermal shock or water erosion to the bearing. In addition, the circulation speed of cooling water in the system is relatively slow, and it cannot be quickly replaced or discharged.

[0005] Therefore, in the existing automobile shock absorber bearing test, when the sample needs to be cooled down, it is often necessary to stop or reduce the speed to ensure that the sample is not damaged during the cooling process and to minimize the impact on the test results. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a high and low temperature integrated box for durability specimens of shock absorbers.

[0007] The technical solution of the present invention is realized by the following scheme: a high and low temperature integrated box for durability test specimens of a shock absorber, comprising a support, an actuator, a loader, a high and low temperature environment spraying studio, a shock absorber test piece and a force sensor, wherein the actuator is installed on the top surface of the cross beam of the support, the output end of the actuator passes through the top surface of the support and the high and low temperature environment spraying studio, the output end of the actuator is flange-connected to the loader, the loader is located in the high and low temperature environment spraying studio, the high and low temperature environment spraying studio is erected in the support through an auxiliary support seat, the auxiliary support seat is straddled on the bottom plate of the support, a force sensor is arranged on the bottom plate of the support, and the shock absorber test piece is detachably installed between the loader and the force sensor; The loader is provided with four workstations, the lower part of the shock absorber test piece is connected to the force sensor through a labyrinth-type height difference waterproof part, a sealing plate is installed between the labyrinth-type height difference waterproof part and the force sensor, and the high and low temperature environment spraying workroom is connected to the feed water tank.

[0008] Through the above technical scheme, the high and low temperature environment spray studio is connected to the feed water tank, and the shock absorber test piece in the studio is spray cooled. Compared with air convection heat dissipation, the cooling water sprayed out by spray cooling can be replaced at a high speed, which can quickly reduce the sample temperature and shorten the test cycle. The high and low temperature studio can withstand different high and low temperature environments to meet different test requirements, and allow durability tests of multiple shock absorber samples to be carried out at the same time. Compared with the single-station test mode, the test efficiency and equipment utilization rate are significantly improved. The normally open spray makes the test surface temperature stable within 70±10℃, and the test can be in the test state all the time without stopping or slowing down. The spray cooling water is completely blocked by the maze-type height difference waterproof part to avoid the impact of cooling water on the sealing plate, thereby ensuring the sealing of the high and low temperature environment spray studio without affecting the normal operation of the force sensor.

[0009] Preferably, the high and low temperature environment spray studio includes a spray cooling device, a high and low temperature environment working box, a sealed observation plate and a bottom reflux tray. The high and low temperature environment working box and the bottom reflux tray are both equipped with a spray cooling device. The sealed observation plate is fixedly mounted on the bottom reflux tray. The high and low temperature environment working box is clamped to the sealed observation plate by a locking piece. The high and low temperature environment working box and the sealed observation plate are both detachably connected to the bottom reflux tray by a buckle. Preferably, the spray cooling device includes a spray water inlet and a return water inlet, the spray water inlet is connected to a feed water tank through a pipeline, and the return water inlet is connected to a feed water tank through a pipeline. The spray water inlet is opened on both sides of the high and low temperature environment working box, the spray water inlet is detachably connected to a nozzle, and the nozzle is located in the high and low temperature environment working box, and the return water inlet is opened on the bottom reflux support plate.

[0010] Preferably, the high and low temperature environment working box is drawable and arranged on an auxiliary support seat through support rollers, and the auxiliary support seat is provided with a slide rail matched with the support rollers.

[0011] Through the above technical scheme, the high and low temperature environment working box, the sealed observation plate and the bottom return plate are tightly combined into a high and low temperature environment spray studio, which can be easily disassembled by means of buckles and locking parts, which not only ensures the stability of the internal environment of the studio during the test, but also makes the maintenance and servicing work simple and quick. The feed water tank cooperates with the nozzle to spray cooling water for temperature control, and the cooling water is quickly replaced and collected through the return water port of the bottom return plate, which quickly absorbs heat and effectively avoids cooling water accumulation and overflow.

[0012] Preferably, four through holes are opened on the bottom reflux support plate, and the through holes correspond to the loader stations one by one. Sealing plates are detachably connected to the four through holes, and the auxiliary support seat abuts against the bottom reflux support plate.

[0013] Preferably, the top surface of the through hole is higher than the bottom surface of the bottom reflux support plate, and the sealing plate is provided with holes adapted to the labyrinth-type height difference waterproofing component.

[0014] Preferably, the labyrinth-type height difference waterproof component comprises a water retaining cap and a transmission rod, the water retaining cap and the transmission rod are integrally arranged, and the water retaining cap is in a basin shape and is inverted on one end of the transmission rod. Preferably, the water retaining cap covers the sealing plate, a shock absorber mounting seat is fixedly mounted on the non-covering surface of the water retaining cap, and the other end of the transmission rod passes through the sealing plate and is connected to the force sensor.

[0015] Through the above technical scheme, the sealing plate is effectively shielded by the maze-type height difference waterproof parts. The position of the sealing plate is higher than the lower part of the edge of the water retaining cap. Through the path height difference, water will not impact the sealing plate to cause leakage risk during spray cooling. The external force sensor of the maze-type waterproof parts can effectively ensure the sealing of the high and low temperature environment chamber working room, and also play the role of transmitting the test force, so that the force sensor can monitor and feedback the mechanical parameters in real time and accurately.

[0016] Preferably, the support member comprises a crossbeam, a base plate and pillars, the base plate supports the crossbeam through the pillars, and the high and low temperature environment spray studio is located between the crossbeam and the base plate.

[0017] Preferably, the force sensor is fixedly mounted on the bottom plate of the support member.

[0018] In summary, the present invention has the following beneficial effects: 1. The present invention connects a feed water tank to a high and low temperature environment spray workroom, and adopts spray cooling for the shock absorber test in the workroom. Compared with air convection heat dissipation, the cooling water sprayed out by spray cooling can be replaced at a high speed, which can quickly reduce the sample temperature and shorten the test cycle. The high and low temperature workroom can withstand different high and low temperature environments to meet different test requirements, and allows durability tests of multiple shock absorber test pieces to be carried out simultaneously. Compared with the single-station test mode, the test efficiency and equipment utilization rate are significantly improved. The normally open spray allows the test surface temperature to be stabilized within 70±10℃, and the test can be in a test state all the time without stopping or slowing down. The spray cooling water is completely blocked by the maze-type height difference waterproof part to avoid the impact of cooling water on the sealing plate, thereby ensuring the sealing of the high and low temperature environment spray workroom without affecting the normal operation of the force sensor.

[0019] 2. The high and low temperature environment working box, sealed observation plate and bottom reflux support plate are integrated into a high and low temperature environment spray studio, which can be easily disassembled by buckles and locking parts, which not only ensures the stability of the internal environment of the studio during the test, but also makes the maintenance and servicing work simple and quick. The feed water tank cooperates with the nozzle to spray cooling water for temperature control. The cooling water is quickly replaced and collected through the return water port of the bottom reflux support plate, which quickly absorbs heat and effectively avoids cooling water accumulation and overflow.

[0020] 3. The sealing plate is effectively shielded by the labyrinth-type height difference waterproof part. The position of the sealing plate is higher than the lower part of the edge of the water retaining cap. The height difference on the path brought by the umbrella-shaped protection will prevent the water from impacting the sealing plate during spray cooling, thus reducing the risk of leakage. The external force sensor of the labyrinth-type waterproof part can effectively ensure the sealing of the high and low temperature environment chamber working room, and also plays the role of transmitting the test force, so that the force sensor can monitor and feedback the mechanical parameters in real time and accurately.

[0021] 4. The crossbeam, bottom plate and pillars constitute a self-reaction frame. The high and low temperature environment working box cooperates with the slide rail on the auxiliary support seat through the support roller, making it easy and smooth to pull out and push in the working box, effectively improving the convenience of equipment replacement and cleaning.

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] A high and low temperature integrated box for durability test specimens of shock absorbers, such as Figure 1-Figure 6 As shown, it includes a support, an actuator 1, a loader 2, a high and low temperature environment spray studio 3, a shock absorber test piece and a force sensor 6.

The output end flange of the actuator 1 is connected to the loader 2. The loader 2 is located in the high and low temperature environment spray studio 3 to simulate extreme temperature conditions and evaluate the performance of the shock absorber test piece at different temperatures. The high and low temperature environment spray studio 3 stands in the support through an auxiliary support seat 7. The auxiliary support seat 7 is straddled on the bottom plate of the support. A force sensor 6 is arranged on the bottom plate of the support. The shock absorber test piece can be detachably installed between the loader 2 and the force sensor 6. A spray cooling device 31 is integrated on the high temperature environment box. The loader 2 is provided with four workstations. The lower part of the shock absorber test piece is connected to the force sensor 6 through a labyrinth height difference waterproof part 4. The labyrinth height difference waterproof part 4 and the force sensor 6 A sealing plate 5 is installed between them, and the high and low temperature environment spray studio 3 is connected to an external feed water tank, which can simultaneously unfold the specimens and apply test forces to four shock absorber test pieces, significantly improving the test efficiency and reducing the test cost. The spray cooling device 31 further enhances the environmental simulation capability of the system and can simulate more complex actual working conditions. The spray cooling seal adopts a height difference labyrinth seal, which effectively avoids the sealing failure problem caused by temperature changes and improves the long-term stability of the system. The force sensor 6 is fixedly installed on the bottom plate of the support. The number of force sensors 6 is consistent with the number of workstations of the loader 2 and corresponds one to one. The shock absorber test piece is tested and inspected. During the test, the most efficient spray cooling is used to cool the specimen. The test surface temperature can be stabilized within 70±10℃, and compared with other cooling methods that have the disadvantage of interrupting the test, the spray cooling can be kept on without stopping the test.

[0027] like Figure 4 and Figure 6As shown, the high and low temperature environment spray studio 3 includes a spray cooling device 31, a high and low temperature environment working box 32, a sealed observation plate 33 and a bottom reflux support plate 34. The high and low temperature environment working box 32 and the bottom reflux support plate 34 are both installed with the spray cooling device 31, the sealed observation plate 33 is fixedly installed on the bottom reflux support plate 34, the high and low temperature environment working box 32 is clamped with the sealed observation plate 33 by a locking member 10, the high and low temperature environment working box 32 and the sealed observation plate 33 are both detachably connected to the bottom reflux support plate 34 by a buckle, and the bottom reflux support plate 34 is a concave cube as a whole, a plurality of buckle upper halves are installed on the high and low temperature environment working box 32 and the sealed observation plate 33, and a matching buckle lower halves are installed on the bottom reflux support plate 34, the high and low temperature environment working box 32, the sealed observation plate 33 and the bottom reflux support plate 34 form a sealed box body, which not only effectively prevents interference from the external environment, but also ensures the experiment After completion, it is convenient to disassemble and repair. The high and low temperature environment working box 32 and the sealed observation plate 33 are plug-in. The top surface of the high and low temperature environment working box 32 is concave, and the top surface of the sealed observation plate 33 is convex. A circular perforation is opened at the center of the clamping connection to facilitate the passage of the actuator 1. Locking holes 10 are opened on both sides of the circular perforation. The locking holes 10 are symmetrically arranged with the center clamping connection as the symmetry line. The insertion end of the locking member 10 is mountain-shaped, and a handle is provided on the back. The locking member 10 is inserted into the clamping hole to clamp and seal the high and low temperature environment working box 32 and the sealed observation plate 33. An observation window is provided in the center of the sealed observation plate 33 for easy observation of the test status. The studio can quickly and evenly adjust and maintain the required high and low temperature environment. At the same time, the spray system can effectively reduce the surface temperature of the test sample and improve the test efficiency. The recessed design of the bottom reflux support plate 34 promotes the reflux and reuse of cooling water, realizing resource conservation and optimization of the circulation system.

[0028] The spray cooling device 31 includes a spray water inlet 311 and a return water port 312. The spray water inlet 311 is connected to the feed water tank through a pipeline, and the return water port 312 is connected to the feed water tank through a pipeline.

The spray water inlet 311 is detachably connected to the nozzle, and the nozzle is located in the high and low temperature environment working box 32. The return water port 312 is opened on the bottom return flow support plate 34. The nozzle preferably uses a spiral nozzle. The spiral nozzle flow channel can minimize liquid blockage to the greatest extent, so that the liquid reaches the maximum flow rate on a pipe of a given size. The nozzle is installed in an upward tilt to effectively cover the working space of the high and low temperature environment studio. The bottom return flow support plate 34 is provided with a hole adapted to the return water port 312 to avoid obstruction of cooling water reflux. The cooling water is replaced at a high speed through the return water port 312 to ensure that the system always remains within the optimal operating temperature range, thereby improving overall performance and stability.

[0029] like Figure 3As shown, the high and low temperature environment working box 32 can be pulled out and set on the auxiliary supporting seat 7 through the supporting roller 9. The auxiliary supporting seat 7 is provided with a slide rail 8 compatible with the supporting roller 9. The supporting parts include a crossbeam, a base plate and a pillar. The base plate supports the crossbeam through the pillar. The high and low temperature environment spray studio 3 is located between the crossbeam and the base plate. The number of pillars is preferably four, which are symmetrically supported. The crossbeam, the base plate and the pillars constitute a self-reaction frame, which can not only bear the weight of the working box and its internal equipment, but also ensure stability during the test or work process. The actuator 1 is connected to the loader 2 through the crossbeam and the high and low temperature environment spray studio 3. Only the buckle and the locking member 10 need to be removed to disassemble the three sealed devices, which can be easily disassembled and reassembled. The high and low temperature environment working box 32 can be adjusted in position or pulled out through the supporting roller 9 to replace the shock absorber test piece or perform maintenance and cleaning, which greatly improves the convenience of replacing the shock absorber test piece or performing maintenance and cleaning, and reduces the complexity and time cost of manual operation.

[0030] like Figure 4 As shown, four through holes are opened on the bottom reflux support plate 34, and the through holes correspond to the workstations of the loader 2 one by one. The four through holes are detachably connected with a sealing plate 5, and the auxiliary support seat 7 abuts the bottom reflux support plate 34. The top surface of the through hole is higher than the bottom surface of the bottom reflux support plate 34. The sealing plate 5 has holes that are compatible with the labyrinth-type height difference waterproofing member 4. The four through holes are opened at the protrusion of the bottom reflux support plate 34, and the top surface of the protrusion is screwed to the sealing plate 5. The bottom reflux support plate 34 itself is placed on the auxiliary support seat 7, and the bottom reflux support plate 34 can be lifted up and then locked by a buckle.

[0031] like Figure 5As shown, the labyrinth height difference waterproof part 4 includes a water retaining cap and a transmission rod, the water retaining cap and the transmission rod are arranged as one body, the water retaining cap is in a basin shape and is buckled on one end of the transmission rod, the water retaining cap covers the sealing plate 5, and the non-covering surface of the water retaining cap is fixedly installed with a shock absorber mounting seat, the shock absorber test piece is connected to the force sensor 6 through the labyrinth height difference waterproof part 4, while taking into account the sealing of the high and low temperature environment studio, the force transmission problem is also effectively solved, the other end of the transmission rod passes through the sealing plate 5 and is connected to the force sensor 6, the position of the sealing plate 5 and the raised top surface of the bottom reflux support plate 34 are higher than the lower part of the outer edge of the labyrinth connector, the labyrinth height difference waterproof part 4 Inserting the holes in the sealing plate 5 forms an umbrella-shaped protection, which ensures that the sealing of the high and low temperature environment chamber working room is not affected, thereby maintaining the stability and accuracy of the environment inside the box. Water will not overflow from the box during spray cooling, and the water flow generated during spray cooling is completely blocked to prevent it from directly impacting the sealing plate 5 and causing sealing failure, affecting the test sample. The labyrinth-type height difference waterproof part 4 not only plays a waterproof sealing role, but also plays a transitional role in transmission force. After being blocked by the water retaining cap, the water will naturally flow to both sides, and finally be effectively collected and refluxed through the return water port 312, avoiding the accumulation of cooling water inside the equipment.

[0032] For example, the buckle lock and feed water tank (not shown) mentioned in the text are all prior art, and the parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The contents not described in detail in this manual belong to the prior art known to professional and technical personnel in this field.

[0033] Working principle: the staff installs four shock absorber test pieces into the loader 2, and the other ends are respectively installed on the shock absorber mounting seats corresponding to the workstations of the loader 2. The staff further slides the high and low temperature environment working box 32 along the slide rail 8 of the auxiliary support seat 7 until the semicircular clamping hole of the actuator 1 of the high and low temperature environment working box 32 and the protruding end of the actuator 1 are mutually clamped. The staff further clamps the sealing observation plate 33 into the high and low temperature environment working box 32 until the semicircular clamping hole of the actuator 1 on the sealing observation plate 33 is clamped with the protruding end of the actuator 1, and the two semicircular clamping holes of the actuator 1 form a full circle. The staff further clamps the locking piece 10 into the clamping hole of the locking piece 10, and assembles the high and low temperature environment working box 32 and the sealing observation plate 33 into a whole. At this time, lift the bottom return plate and fix it to the bottom of the high and low temperature environment working box 32 and the sealing observation plate 33 through multiple buckles. At this time, the three are combined to form a high and low temperature environment working room; Start the actuator 1 to test the four shock absorber test pieces, and at the same time, supply water to the nozzle through the feed water tank to spray. The test surface temperature is stabilized within 70±10℃. The sprayed cooling water will naturally flow to both sides after being blocked by the water retaining cap, and finally be effectively collected and refluxed through the return water port 312; After the test is completed, the three parts can be disassembled by simply opening the buckle and disassembling the locking member 10 for replacement or cleaning.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields.
