Technical Field

[0001] This utility model relates to the field of sealing component testing technology, and in particular to a steam jet testing fixture for automotive sealing components. Background Technology

[0002] With the continuous advancement of automotive technology and the increasing expectations of consumers for vehicle performance, automotive seals, as a key component of automobiles, directly impact the overall performance and safety of the vehicle. Steam jet testing, as an advanced testing method, simulates the steam jet impacts that seals may encounter in real-world environments, mimicking harsh conditions, to evaluate their durability and sealing performance.

[0003] For example, Chinese Patent Publication No. CN204953210U discloses a steam jet testing fixture for automotive seals, which includes a bracket consisting of a horizontal part and a vertical part. A vertical intermediate bracket, parallel to the vertical bracket, is provided on the top surface of the horizontal part of the bracket. A horizontal beam, parallel to the vertical bracket and arranged horizontally, is fixed to the side of the intermediate bracket facing the vertical bracket for fixing the test sample. A horizontal spray gun support plate is fixed on the vertical bracket, with the top surface of the spray gun support plate higher than the top surface of the beam. A top beam is provided at the top of the vertical bracket, and the spray gun is fixed to the spray gun support plate and the top beam.

[0004] When the vapor jet testing device for seals in the above application is used to test multiple seals, it can only test a single seal at a time. It requires repeated installation, disassembly and replacement of seals for testing, which affects the continuity and efficiency of the overall test. At the same time, the operation of fixing and removing the seals is inconvenient, which affects the convenience of use.

[0005] Therefore, it is necessary to provide a vapor jet testing fixture for automotive seals to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a steam jet testing fixture for automotive seals to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A steam jet testing fixture for automotive seals includes a worktable. A shaft tube is rotatably connected to the center of the worktable. A connecting rod is fixed to the top end of the shaft tube. Multiple connecting rods are arranged in a ring. A placement plate is fixed to the end of each connecting rod away from the shaft tube. A support plate is fixed to the top side of the worktable. A jet pipe is fixed to the top of the support plate. The outlet of the jet pipe faces downward. A turning assembly for driving the shaft tube to rotate and adjust is provided at the bottom of the worktable. A suction assembly for adsorbing and fixing the seal is provided on the placement plate.

[0008] As a further embodiment of this utility model, the turning assembly includes a servo motor disposed at the bottom of the workbench, a first gear fixed at the bottom end of the shaft tube, a second gear meshing with the first gear fixed at the output end of the servo motor, and a PLC controller electrically connected to the servo motor fixed on the bottom side of the workbench.

[0009] As a further embodiment of this utility model, the suction assembly includes a suction pipe that is rotatably connected to the bottom end of the shaft tube and communicates with the inside of the shaft tube. The connecting rod has a through cavity that communicates with the inside of the shaft tube. The placement plate has a cavity that communicates with the through cavity. The top surface of the placement plate has a suction hole that communicates with the cavity.

[0010] As a further embodiment of this utility model, the suction holes are provided in multiple locations, and the multiple suction holes are concentrated at the center of the top surface of the placement plate.

[0011] As a further embodiment of this utility model, a groove is provided on the top side of the placement plate.

[0012] As a further embodiment of this utility model, a support rod is fixed on the bottom side of the workbench, the servo motor is fixed to the support rod, and a plurality of symmetrically distributed support legs are fixed on the bottom side of the workbench.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] After the seal located directly below the jet pipe completes the steam jet test within a fixed time period, the PLC controller controls the rotating component to rotate the shaft tube by a certain angle. The shaft tube, through the connecting rod, synchronously drives the placement plate to rotate and adjust, thereby transferring the seal on another placement plate to directly below the jet pipe for steam jet testing. This process is repeated, allowing multiple seals on multiple placement plates to be sequentially switched and transferred to below the outlet of the jet pipe for steam jet testing. This eliminates the need for manual replacement of seals for steam jet testing, effectively improving the continuity of steam jet testing and thus increasing the overall testing efficiency of multiple seals.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5This utility model provides a steam jet testing fixture for automotive seals, including a workbench 3. A shaft tube 6 is rotatably connected to the center of the workbench 3. A connecting rod 7 is fixed to the top of the shaft tube 6. Multiple connecting rods 7 are arranged in a ring. A placement plate 5 is fixed to the end of each connecting rod 7 away from the shaft tube 6. A support plate 8 is fixed to the top side of the workbench 3. A jet pipe 9 is fixed to the top of the support plate 8, with the outlet of the jet pipe 9 facing downwards. A turning component 2 for driving the shaft tube 6 to rotate and adjust is provided at the bottom of the workbench 3. A suction and fixing component 1 for adsorbing and fixing the seals is provided on the placement plate 5. In use, multiple seals to be tested are placed on the top sides of multiple placement plates 5, and the suction and fixing component 1 simultaneously adsorbs and fixes the multiple seals to the top of multiple placement plates 5, thereby effectively improving the convenience of fixing and placing multiple seals, and facilitating the placement and removal of seals. At this time, one of the placement plates 5 is positioned directly opposite the outlet of the jet pipe 9. Below, a steam generator is connected to the jet pipe 9. Hot steam is sprayed through the jet pipe 9 onto the seal on the top of the placement plate 5 to perform a steam jet test on the seal. The jet pipe 9 is fixed in place with screws and different jet pipes 9 can be replaced. The jet outlet of the jet pipe 9 can be adjusted to a 45-degree angle with the top surface of the placement plate 5. After the seal located directly below the jet pipe 9 has completed the steam jet test for a fixed period of time, the PLC controller 12 controls the rotating component 2 to rotate the shaft tube 6 by a certain angle. The shaft tube 6 drives the placement plate 5 to rotate and adjust synchronously through the connecting rod 7, thereby transferring the seal on another placement plate 5 to directly below the jet pipe 9 for steam jet testing. This process is repeated to sequentially switch multiple seals on multiple placement plates 5 to the outlet of the jet pipe 9 for steam jet testing, eliminating the need for manual replacement of seals for steam jet testing, effectively improving the continuity of steam jet testing, and thus improving the overall testing efficiency of multiple seals.

[0025] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the turning component 2 includes a servo motor 203 located at the bottom of the workbench 3, a first gear 201 fixed at the bottom end of the shaft tube 6, a second gear 202 meshing with the first gear 201 fixed at the output end of the servo motor 203, and a PLC controller 12 electrically connected to the servo motor 203 fixed on the side of the bottom end of the workbench 3. In specific operation, after the seal located directly below the jet pipe 9 has completed the steam jet test for a fixed period of time, the PLC controller 12 controls the servo motor 203 to drive the second gear 202 to rotate. Thus, the second gear 202 and the first gear 201 work together to drive the shaft tube 6 to rotate a certain angle. The shaft tube 6 drives the placement plate 5 to rotate and adjust synchronously through the connecting rod 7, thereby transferring the seal on another placement plate 5 to directly below the jet pipe 9 for steam jet testing. This process is repeated to sequentially switch multiple seals on multiple placement plates 5 to be transferred to the outlet of the jet pipe 9 for steam jet testing.

[0026] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the suction assembly 1 includes a suction pipe 103 rotatably connected to the bottom end of the shaft tube 6 and communicating with the inside of the shaft tube 6. The connecting rod 7 has a through cavity 102 communicating with the inside of the shaft tube 6. The placement plate 5 has a cavity 101 communicating with the through cavity 102. The top surface of the placement plate 5 has a suction hole 104 communicating with the cavity 101. In specific operation, the suction pipe 103 is connected to a suction pump. The suction pipe 103 draws air into the shaft tube 6, the through cavity 102 and the cavity 101, thereby creating a negative pressure suction inside the cavity 101. The sealing element placed on the top of the placement plate 5 is then adsorbed and fixed through multiple suction holes 104. This allows multiple sealing elements to be simultaneously adsorbed and fixed to the top of multiple placement plates 5, thereby effectively improving the convenience of fixing and placing multiple sealing elements and facilitating the placement and removal of the sealing elements.

[0027] This solution has the following working process: By placing multiple seals to be tested on the top sides of multiple placement plates 5, suction is drawn into the shaft tube 6, through cavity 102 and cavity 101 through suction pipe 103, thereby creating negative pressure suction inside cavity 101. This allows the seals placed on the top of the placement plates 5 to be adsorbed and fixed through multiple suction holes 104, achieving simultaneous adsorption and fixation of multiple seals on the top of multiple placement plates 5. After the seal located directly below the jet pipe 9 has completed the steam jet test for a fixed period of time, the PLC controller 12 controls the servo motor 203 to drive the second gear 202 to rotate. The second gear 202 and the first gear 201 work together to drive the shaft tube 6 to rotate a certain angle. The shaft tube 6 drives the placement plate 5 to rotate and adjust synchronously through the connecting rod 7, thereby transferring the seal on another placement plate 5 to directly below the jet pipe 9 for steam jet test. This process is repeated, thereby allowing multiple seals on multiple placement plates 5 to be sequentially transferred to below the air outlet of the jet pipe 9 for steam jet test.

[0028] Further as Figure 4 and Figure 5 As shown, it is worth noting that there are multiple suction holes 104, and these multiple suction holes 104 are concentrated at the center of the top surface of the placement plate 5.

[0029] Further as Figure 4 and Figure 5 As shown, it is worth noting that a groove 11 is provided on the top side of the placement plate 5; in actual operation, the groove 11 facilitates the placement of the sealing element on the top of the placement plate 5.

[0030] Further as Figure 3 As shown, it is worth noting that a support rod 10 is fixed on the bottom side of the worktable 3, the servo motor 203 is fixed to the support rod 10, and multiple symmetrically distributed support legs 4 are fixed on the bottom side of the worktable 3.

[0031] In summary: By using the suction and fixing component 1 to simultaneously adsorb and fix multiple seals onto the tops of multiple placement plates 5, the convenience of fixing and placing multiple seals is effectively improved, making it easier to place and remove the seals. After the seal located directly below the jet pipe 9 has completed the steam jet test for a fixed period of time, the PLC controller 12 controls the turning component 2 to rotate the shaft tube 6 by a certain angle. The shaft tube 6 drives the placement plate 5 to rotate and adjust synchronously through the connecting rod 7, thereby transferring the seal on another placement plate 5 to directly below the jet pipe 9 for steam jet testing. This process is repeated, allowing multiple seals on multiple placement plates 5 to be sequentially switched and transferred to the outlet of the jet pipe 9 for steam jet testing. This eliminates the need for manual replacement of seals for steam jet testing, effectively improving the continuity of steam jet testing and thus increasing the overall testing efficiency of multiple seals.

[0032] The servo motor 203 and PLC controller 12 can be purchased from the market. The servo motor 203 and PLC controller 12 are equipped with power supplies. They are mature technologies in the field and have been fully disclosed. Therefore, they will not be described again in the specification.
