Description

Technical Field

[0001] This utility model relates to the technical field of automobile testing, and in particular to a fully automatic powertrain testing device. Background Technology

[0002] Currently, as a core component of automobiles, the powertrain needs to undergo performance tests such as torque and noise before the vehicle is assembled. At present, the powertrain performance tests are mainly carried out on powertrain test benches.

[0003] In related technologies, powertrain test benches mainly consist of a bench system, an automated control system, a data acquisition system, and bench auxiliary equipment. The bench system mainly consists of a load motor, a torque sensor, and test specimen mounting supports. The load motor can move axially to accommodate different test specimen sizes.

[0004] In the process of developing this application, at least the following problems were found in the technology: During testing, the powertrain is directly connected to the load motor and clamped from both ends. When testing a larger powertrain, the torque is large, and the stability of the powertrain is poor, resulting in powertrain deflection. Therefore, this needs to be improved. Utility Model Content

[0005] To improve the stability of powertrain testing and prevent powertrain deflection due to excessive torque, this application provides a fully automated powertrain testing device.

[0006] The fully automated powertrain testing equipment provided in this application adopts the following technical solution:

[0007] A fully automatic powertrain testing device includes a frame, a transmission frame, a stopper, a test frame, a load motor, a tray, and a support platform. The test frame, transmission frame, and stopper are located on the frame, with the stopper positioned between the transmission frames and the transmission frames positioned between the test frames. The load motor is mounted on the test frame. Several transmission wheels are rotatably mounted on the transmission frame, abutting against the tray. A transmission mechanism is provided on the transmission frame to drive the simultaneous rotation of the transmission wheels. The support platform is located between the transmission frames, and a lifting mechanism is provided on the frame to drive the support platform to rise and fall. A load-bearing frame is provided on the frame, and several Z-axis electric cylinders are threaded through the load-bearing frame. The piston rods of the Z-axis electric cylinders are connected to pressure heads. A translation mechanism connected to the Z-axis electric cylinders is provided on the load-bearing frame, and the translation mechanism is used to drive the Z-axis electric cylinders to slide on a horizontal plane.

[0008] By adopting the above technical solution, during powertrain testing, the powertrain to be tested is fixed on a pallet. The pallet is transferred to a transfer frame through a process. The transfer mechanism drives several transfer wheels to rotate, and the transfer wheels abut against the pallet, moving the pallet between the test frames. A stopper limits the pallet, positioning it directly above the support platform. The lifting mechanism then moves the support platform against the pallet, raising the pallet. The test frame then slides, connecting the load motor to the powertrain on the pallet. Simultaneously, a translation mechanism moves several Z-axis electric cylinders horizontally, moving the clamping head directly above the powertrain. The Z-axis electric cylinders abut against the top of the powertrain, thus improving the stability of the pallet on the support platform during testing and preventing the powertrain from deflecting due to excessive torque. The translation mechanism can also change the position of the Z-axis electric cylinders on the support frame, facilitating testing of different powertrain models.

[0009] Preferably, three Z-axis electric cylinders are provided.

[0010] By adopting the above technical solution, the three clamping heads simultaneously abut against the top of the powertrain, resulting in a good clamping effect.

[0011] Preferably, the translation mechanism includes an X-axis electric cylinder, an X-axis slide, a Y-axis electric cylinder, and a Y-axis slide. The X-axis electric cylinder is mounted on a support frame, and its piston rod is connected to the X-axis slide. The Y-axis electric cylinder is mounted on the X-axis slide, and its piston rod is connected to the Y-axis slide. The Z-axis electric cylinder is mounted on the Y-axis slide.

[0012] By adopting the above technical solution, the operation of the X-axis electric cylinder can drive the X-axis slide table to slide, and the operation of the Y-axis electric cylinder can drive the Y-axis slide table to slide, thereby realizing the rapid control of the Z-axis electric cylinder to slide along the length or width of the support frame, which facilitates the rapid adjustment of the position of the Z-axis electric cylinder, so as to facilitate the testing of different models of powertrain.

[0013] Preferably, the translation mechanism further includes a floating guide bearing, which is disposed between the Z-axis electric cylinder and the Y-axis slide.

[0014] By adopting the above technical solution, when the Z-axis electric cylinder drives the pressing head to abut against the top of the powertrain, the floating guide bearing can automatically control the Z-axis electric cylinder to stop working, improving the automation level of the pressing action and facilitating the pressing of powertrains at different heights.

[0015] Preferably, the transmission mechanism includes a transmission motor, gears, chains, and a linkage shaft. The gears are mounted on the end walls of the transmission wheels, the chains mesh with the gears, the transmission motor is mounted on the transmission frame, the drive shaft of the transmission motor is connected to one of the gears, and the linkage shaft is connected between the transmission wheels.

[0016] By adopting the above technical solution, after the pallet is transported to the transfer wheel, the transfer motor drives one of the gears to rotate. The gear drives several transfer wheels on one side of the transfer frame to rotate simultaneously through the chain. The linkage shaft then drives the transfer wheel on the other side of the transfer frame to rotate. The pallet can be controlled to move on the transfer frame by the transfer wheel abutting against the bottom of the pallet.

[0017] Preferably, a set of wear-resistant plates are symmetrically arranged at the bottom of the tray, and the transmission wheel abuts against the wear-resistant plates.

[0018] By adopting the above technical solution, the wear-resistant plate increases the friction between the transmission wheel and the pallet, making it easier for the transmission wheel to move the pallet. The wear-resistant plate also helps to reduce the damage to the pallet.

[0019] Preferably, the lifting mechanism includes guide rods and a servo lift. Several guide rods are symmetrically arranged on the frame. The support platform is slidably mounted on the guide rods. The servo lift is mounted on the frame and connected to the support platform.

[0020] By adopting the above technical solution, after the pallet is stopped by the stopper, the servo lift works, and the guide rod guides the support platform, which can quickly control the support platform to be raised away from the transmission frame.

[0021] Preferably, the upper surface of the support platform is symmetrically provided with a number of positioning posts, and the lower surface of the tray is provided with positioning holes for the positioning posts to be inserted.

[0022] By adopting the above technical solution, when the lifting mechanism drives the support platform to abut against the bottom of the pallet, the positioning column can be inserted into the positioning hole. The cooperation between the positioning column and the positioning hole can quickly position the pallet on the support platform, while improving the stability of the pallet on the support platform.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a transmission wheel, transmission mechanism, support platform, lifting mechanism, load-bearing frame, Z-axis electric cylinder, clamping head, and translation mechanism, during powertrain testing, the powertrain to be tested is fixed on the tray. The transmission mechanism moves the tray between the test frames, the stopper limits the tray, the lifting mechanism moves the support platform to abut against the tray, and at the same time the translation mechanism works, moving several Z-axis electric cylinders to slide on the horizontal plane, so that the clamping head moves to directly above the powertrain. The Z-axis electric cylinders work to make the clamping head abut against the top of the powertrain, thereby improving the stability of the tray on the support platform during testing and preventing the powertrain from deflecting due to excessive torque. The translation mechanism can change the position of the Z-axis electric cylinders on the load-bearing frame, which is convenient for testing different models of powertrain.

[0025] 2. By setting up an X-axis electric cylinder, an X-axis slide, a Y-axis electric cylinder, a Y-axis slide, and a floating guide bearing, the operation of the X-axis electric cylinder can drive the X-axis slide to slide, and the operation of the Y-axis electric cylinder can drive the Y-axis slide to slide, thereby realizing the rapid control of the Z-axis electric cylinder to slide along the length or width of the support frame. This facilitates the quick adjustment of the position of the Z-axis electric cylinder, which is convenient for testing different models of power assemblies. The floating guide bearing facilitates the automatic clamping of power assemblies at different heights during testing.

[0026] 3. By setting positioning columns and positioning holes, when the lifting mechanism drives the support platform to abut against the bottom of the pallet, the positioning columns can be inserted into the positioning holes. The cooperation between the positioning columns and positioning holes can quickly position the pallet on the support platform, while improving the stability of the pallet on the support platform.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a fully automated powertrain testing device. (Refer to...) Figure 1The system includes a frame 1, a transfer frame 11, a stopper 12, a test frame 13, a load motor 14, a tray 2, and a support platform 3. The test frame 13, transfer frame 11, and stopper 12 are all mounted on the frame 1. The transfer frame 11 is located between the test frames 13, and the stopper 12 is located between the transfer frames 11. The test frame 13 is slidably connected to the frame 1, and the load motor 14 is mounted on the test frame 13. Several transfer wheels 111 are symmetrically arranged on both sides of the transfer frame 11, and the tray 2 is located on the transfer wheels 111, with the transfer wheels 111 abutting against the lower surface of the tray 2. A transfer mechanism 4 is mounted on the transfer frame 11. During powertrain testing, the powertrain to be tested is fixed on the tray 2. The tray 2 is transferred to the transfer frame 11 through a process. The transfer mechanism 4 drives the several transfer wheels 111 to rotate, and the transfer wheels 111 abut against the tray 2, causing the tray 2 to move. The stopper 12 limits the movement of the tray 2, allowing it to move between the two test frames 13.

[0034] Reference Figures 1 to 3 The support platform 3 is located between the transmission frames 11. A lifting mechanism 5 connected to the support platform 3 is installed on the frame 1. A support frame 15 is fixed to the frame 1 by bolts. Several Z-axis electric cylinders 6 are installed through the support frame 15. In this embodiment, three Z-axis electric cylinders 6 are installed, with their length direction along the vertical direction. A translation mechanism 7 connected to the Z-axis electric cylinders 6 is installed on the support frame 15. When the tray 2 is transferred to the test frame 13, the tray 2 is directly above the support platform 3. The lifting mechanism 5 operates, causing the support platform 3 to abut against the tray 2, raising the tray 2. Then, the test frame 13 slides, driving the load motor 14 to connect to the power assembly on the tray 2. Simultaneously, the translation mechanism 7 operates, causing the Z-axis electric cylinders 6 to slide horizontally, controlling the pressing head 61 to move directly above the power assembly. The Z-axis electric cylinders 6 work to make the pressing head 61 abut against the top of the power assembly, thereby improving the stability of the tray 2 on the support platform 3 during testing.

[0035] Reference Figure 1 and Figure 2The translation mechanism 7 includes an X-axis electric cylinder 71, an X-axis slide 72, a Y-axis electric cylinder 73, a Y-axis slide 74, and a floating guide bearing 75. The X-axis electric cylinder 71 is fixedly mounted on the support frame 15 by bolts and is arranged along the length of the support frame 15. The piston rod of the X-axis electric cylinder 71 is connected to the X-axis slide 72. The Y-axis electric cylinder 73 is fixedly mounted on the X-axis slide 72 by bolts and is arranged along the length of the support frame 15. The piston rod of the Y-axis electric cylinder 73 is connected to the Y-axis slide 74. The Z-axis electric cylinder 6 is mounted on the Y-axis slide 74 by bolts. The floating guide bearing 75 is located between the Z-axis electric cylinder 6 and the Y-axis slide 74. The operation of the X-axis electric cylinder 71 can drive the X-axis slide table 72 to slide, and the operation of the Y-axis electric cylinder 73 can drive the Y-axis slide table 74 to slide. This enables rapid control of the Z-axis electric cylinder 6 to slide along the length or width of the support frame 15, facilitating quick changes in the position of the Z-axis electric cylinder 6 for testing different powertrain models. The floating guide bearing 75 can automatically control the Z-axis electric cylinder 6 to automatically adapt and adjust during clamping, improving the automation and applicability of the clamping action.

[0036] Reference Figure 1 The transmission mechanism 4 includes a transmission motor 41, a gear 42, a chain 43, and a linkage shaft 44. The gear 42 is mounted on one end of the transmission wheel 111 and is coaxial with the transmission wheel 111. The chain 43 meshes with the gear 42. The transmission motor 41 is fixedly mounted on the transmission frame 11. The drive shaft of the transmission motor 41 is connected to one of the gears 42. The linkage shaft 44 is connected between the transmission wheels 111. After the tray is transported onto the transmission wheel 111, the transmission motor 41 drives one of the gears 42 to rotate. The gear 42 drives several transmission wheels 111 on one side of the transmission frame 11 to rotate simultaneously via the chain 43. The linkage shaft 44 then drives the transmission wheels 111 on the other side of the transmission frame 11 to rotate. The transmission wheels 111 abut against the bottom of the tray 2, which controls the movement of the tray 2 along the length of the transmission frame 11.

[0037] Reference Figure 4 A set of wear-resistant plates 21 are symmetrically arranged at the bottom of the pallet 2. The transmission wheel 111 abuts against the wear-resistant plate 21. The wear-resistant plate 21 increases the friction between the transmission wheel 111 and the pallet 2, which makes it easier for the transmission wheel 111 to drive the pallet 2 to move. At the same time, it also helps to reduce the damage to the pallet 2 and extend the service life of the pallet 2.

[0038] Reference Figure 3The lifting mechanism 5 includes guide rods 51 and servo lift 52. Several guide rods 51 are symmetrically arranged on the frame 1. The support platform 3 is slidably arranged on the guide rods 51. The servo lift 52 is arranged on the frame 1 and connected to the support platform 3. After the tray 2 is limited by the stopper 12, the servo lift 52 works, and the guide rods 51 guide the support platform 3, so that the support platform 3 can be quickly controlled to be raised away from the transmission frame 11.

[0039] Reference Figure 3 and Figure 4 The upper surface of the support platform 3 is symmetrically provided with several positioning posts 8. The top of the positioning posts 8 is inclined. The lower surface of the tray 2 is provided with positioning holes 81 for the positioning posts 8 to be inserted. The positioning holes 81 and the positioning posts 8 are mutually adapted. When the lifting mechanism 5 drives the support platform 3 to abut against the bottom of the tray 2, the positioning posts 8 can be inserted into the positioning holes 81. The cooperation between the positioning posts 8 and the positioning holes 81 can quickly position the tray 2 on the support platform 3, and at the same time improve the stability of the tray 2 on the support platform 3.

[0040] The implementation principle of a fully automatic powertrain testing device according to an embodiment of this application is as follows: During powertrain testing, the powertrain to be tested is fixed on a tray 2. The tray 2 is transferred to a transfer frame 11 through a process. The transfer mechanism 4 drives several transfer wheels 111 to rotate. The transfer wheels 111 abut against the tray 2, causing the tray 2 to move between the test frames 13. Then, the stop device 12 limits the tray 2, so that the tray 2 is directly above the support platform 3. Then, the lifting mechanism 5 works to drive the support platform 3 to abut against the tray 2, causing the tray 2 to rise. Then, the test frame 13 slides the working belt. The dynamic load motor 14 is connected to the power assembly on the tray 2. At the same time, the translation mechanism 7 works, driving several Z-axis electric cylinders 6 to slide on the horizontal plane, controlling the pressing head 61 to move directly above the power assembly. The Z-axis electric cylinders 6 work to make the pressing head 61 abut against the top of the power assembly, thereby improving the stability of the tray 2 on the support platform 3 during testing and preventing the power assembly from deflecting due to excessive torque. The translation mechanism 7 can change the position of the Z-axis electric cylinders 6 on the support frame 15, which is convenient for testing different models of power assemblies. The equipment has a high degree of automation and applicability.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
