Description

Technical Field

[0001] The present application relates to the field of automobile processing, and in particular to a tooling fixture for an automobile steering assembly. Background Art

[0002] The automobile steering assembly mainly includes the automobile steering gear, which is also known as the steering machine or steering gear. It is the most important component in the automobile steering system. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission. The automobile steering gear is usually cylindrical in the middle with protective bellows at both ends. When processing the automobile steering gear, a clamp is needed to fix the steering gear.

[0003] Existing processing fixtures usually place the car steering gear directly on the fixture. When the fixture is tightened, a large area of ​​the steering gear is covered by the fixture, resulting in the need to frequently adjust the clamping position to change the upward position of the steering gear during processing. At the same time, existing fixtures usually use a single cylinder extension for clamping, and manual assistance is required when limiting the steering gear, which is inconvenient and dangerous. Utility Model Content

[0004] In order to solve the problem that a large area of ​​the steering gear is covered by the fixture, resulting in the need to frequently adjust the clamping position to change the upward position of the steering gear during processing, the present application provides an automobile steering assembly tooling fixture.

[0006] By adopting the above technical solution, the forward and reverse rotation of the first servo motor drives the threaded sleeve to rotate outside the threaded rod, thereby driving the horizontal height of the lifting platform to change

[0007] Preferably, the power output end of the second servo motor is movable through the middle of the bottom of the lifting platform, and the driving gear is located in the middle of the inner wall of the lifting platform.

[0008] By adopting the above technical solution, the second servo motor rotates to drive the driving gear inside the lifting platform to rotate.

[0009] Preferably, the two driven racks are arranged with teeth facing each other and in parallel, and the driving gear is respectively engaged with the two driven racks.

[0010] By adopting the above technical solution, the driving gear rotates to drive the two driven racks to move horizontally, so that the two extrusion plates can move closer to the middle at the same time.

[0011] Preferably, the maximum length of the first set of rods and the telescopic rod is greater than the length of the support rod, and at least two first sets of rods and telescopic rods are provided, which are respectively located on both sides of the middle of the bottom of the lifting platform.

[0012] By adopting the above technical solution, the first set of rods and the telescopic rod limit the lifting platform to prevent the lifting platform from rotating along with the rotation of the threaded sleeve. At the same time, the telescopic rod telescopes inside the first set of rods without affecting the up and down movement of the lifting platform.

[0013] Preferably, optical distance sensors are fixed to the top and bottom of one end of the extrusion plate, and a pressure sensor is fixed to the middle of the extrusion plate.

[0014] By adopting the above technical solution, two optical distance sensors are used to detect whether the lifting platform has been lifted to the bottom of the diverter and is in contact with it. When the value of the bottom optical distance sensor changes, the value of the top optical distance sensor also changes, indicating that the diverter is now located in the middle of the two optical distance sensors. The pressure sensor is used to determine whether the extrusion plate has successfully squeezed the diverter.

[0015] Preferably, the two optical distance sensors and the pressure sensor are electrically connected to the control switch, and the first servo motor and the second servo motor are electrically connected to the control switch.

[0016] By adopting the above technical solution, the control switch starts the first servo motor to control the lifting platform to rise. When the value of the bottom optical distance sensor changes and the value of the top optical distance sensor also changes, the first servo motor stops and the second servo motor starts. When the pressure sensor determines that the extrusion plate has squeezed the diverter, the second servo motor stops and controls the first servo motor to continue rotating, extending the diverter to the highest point.

[0017] Preferably, a placement groove is provided in the middle of the top of each of the two support rods, and the placement groove is arranged in an arc shape.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application uses a first servo motor to control the lifting platform to rise, and then controls the second servo motor to start. The driving gear rotates to drive the two driven racks to move horizontally, so that the two extrusion plates can simultaneously move closer to the middle. When the pressure sensor determines that the extrusion plates have squeezed the steering gear, the second servo motor stops and controls the first servo motor to continue rotating, extending the steering gear to the highest position, thereby keeping the steering gear suspended during clamping and reducing the area blocked by the steering gear.

[0021] 2. This application can be achieved by placing the steering gear in the placement grooves on the top of the two support rods. The arc-shaped placement grooves can prevent the steering gear from rolling. The steering gear can then be limited by controlling the switch, thereby achieving a more convenient and safer effect without the need for manual assistance during clamping.

[0027] The following is combined with Figures 1-4 This application is described in further detail.

[0028] The embodiment of the present application discloses a vehicle steering assembly fixture, including a base plate 1, a control switch 2 is fixed to one side of the base plate 1, a support rod 3 is fixed to the middle of both ends of the top of the base plate 1, a first set of rods 9 is fixed to the top of the base plate 1, a telescopic rod 10 is movably sleeved on the top of the first set of rods 9, a lifting platform 12 is fixed to the top of the telescopic rod 10, a second servo motor 11 is fixed to the middle of the bottom of the lifting platform 12, a driving gear 18 is fixed to the power output end of the second servo motor 11, and a driven rack is slidably connected to both sides of the inner wall of the lifting platform 12 13. Extrusion plates 14 are fixed to the tops of the opposite ends of the two driven racks 13. Extrusion grooves 15 are provided on the opposite sides of the two extrusion plates 14. A first servo motor 5 is fixed to the middle part of one side of the top of the base plate 1. A threaded sleeve 6 is fixed to the power output end of the first servo motor 5. The threaded sleeve 6 is internally threadedly connected to a threaded rod 7. The top of the threaded rod 7 is fixed to the lifting platform 12. The forward and reverse rotation of the first servo motor 5 drives the threaded sleeve 6 to rotate outside the threaded rod 7, thereby driving the horizontal height of the lifting platform 12 to change.

[0029] Among them, the power output end of the second servo motor 11 runs through the middle of the bottom of the lifting platform 12, and the driving gear 18 is located in the middle of the inner wall of the lifting platform 12. By rotating the second servo motor 11, the driving gear 18 inside the lifting platform 12 can be driven to rotate.

[0030] Among them, the two driven racks 13 are arranged with teeth facing each other and in parallel, and the driving gear 18 is respectively engaged with the two driven racks 13. The driving gear 18 rotates to drive the two driven racks 13 to move horizontally, so that the two extrusion plates 14 can move closer to the middle at the same time.

[0031] Among them, the maximum length value of the first set of rods 9 and the telescopic rod 10 is greater than the length value of the support rod 3, and there are at least two first sets of rods 9 and telescopic rods 10, which are respectively located on both sides of the middle part of the bottom of the lifting platform 12. The lifting platform 12 is limited by the first set of rods 9 and the telescopic rod 10 to prevent the lifting platform 12 from rotating together with the rotation of the threaded sleeve 6. At the same time, the telescopic rod 10 is telescoped inside the first set of rods 9 without affecting the up and down movement of the lifting platform 12.

[0032] Among them, optical distance sensors 17 are fixed at the top and bottom of one end of the extrusion plate 14, and a pressure sensor 16 is fixed in the middle of the extrusion plate 14. The two optical distance sensors 17 are used to detect whether the lifting platform 12 is lifted to the bottom of the diverter 19 and fits with it. When the value of the bottom optical distance sensor 17 changes, the value of the top optical distance sensor 17 also changes, indicating that the diverter 19 is located in the middle of the two optical distance sensors 17 at this time. The pressure sensor 16 is used to determine whether the extrusion plate 14 has successfully squeezed the diverter 19.

[0033] Among them, the two optical distance sensors 17 and the pressure sensor 16 are electrically connected to the control switch 2, and the first servo motor 5 and the second servo motor 11 are electrically connected to the control switch 2. The first servo motor 5 is started by the control switch 2 to control the lifting platform 12 to rise. When the value of the bottom optical distance sensor 17 changes and the value of the top optical distance sensor 17 also changes, the first servo motor 5 stops and the second servo motor 11 starts. When the pressure sensor 16 determines that the extrusion plate 14 has squeezed the diverter 19, the second servo motor 11 stops and controls the first servo motor 6 to continue rotating to extend the diverter 19 to the highest point.

[0034] Among them, a placement groove 4 is opened in the middle of the top of the two support rods 3, and the placement groove 4 is arranged in an arc shape. When clamping, the diverter 19 can be directly placed in the placement groove 4 on the top of the two support rods 3. The arc-shaped placement groove 4 can prevent the diverter 19 from rolling.

[0035] The implementation principle of the automobile steering assembly fixture of the embodiment of the present application is as follows: when clamping, the steering gear 19 can be directly placed in the placement groove 4 at the top of the two support rods 3. The arc-shaped placement groove 4 can prevent the steering gear 19 from rolling. Then, the first servo motor 5 is started by the control switch 2 to control the lifting platform 12 to rise, driving the threaded sleeve 6 to rotate outside the threaded rod 7, thereby driving the horizontal height of the lifting platform 12 to rise. The lifting platform 12 is limited by the first set of rods 9 and the telescopic rod 10 to prevent the lifting platform 12 from rotating together with the rotation of the threaded sleeve 6. At the same time, the telescopic rod 10 is retracted inside the first set of rods 9 without affecting the up and down movement of the lifting platform 12. When the lifting platform 12 rises, the value of the bottom optical distance sensor 17 changes and the value of the top optical distance sensor 17 also changes. At this time, the control switch 2 controls the first servo motor 5 to stop, and the second servo motor 11 is started at the same time. The two driven racks 13 are driven to move horizontally through the rotation of the driving gear 18, so that the two extrusion plates 14 can move closer to the middle at the same time. When the pressure sensor 16 determines that the extrusion plate 14 has squeezed the diverter 19, the second servo motor 11 stops and controls the first servo motor 6 to continue rotating, extending the diverter 19 to the highest point. At this time, the limit of the diverter 19 is completed, and the diverter 19 is only in contact with the extrusion plate 14.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
