[0002] There are currently two common methods for testing the starting torque of the brake disc of the steering knuckle assembly: one is off-line testing, where the assembled product is manually moved to the off-line testing equipment for testing. This method increases manual operation, is time-consuming and labor-intensive, and does not meet production needs; the other is that after the steering knuckle assembly flows along the line to the testing station, the steering knuckle assembly is flipped 180° by a robot or manually before the starting torque test is performed. This testing method requires more mechanisms, has a complex structure, and has a longer test cycle. Utility Model Content

[0010] In some embodiments, the product tooling includes a locating seat, which is installed on the base plate through a locating pin. A locating hole and a connecting hole are provided in the locating seat. The locating hole is used to cooperate with the brake disc. A first pin hole is provided at one end of the locating seat. The static friction force between the locating seat and the brake disc is greater than the starting torque of the steering knuckle assembly. The locating seat cooperates with the torque testing mechanism through the connecting hole and the first pin hole, so that the torque testing mechanism can drive the locating seat to rotate.

[0011] In some embodiments, the first-level lifting mechanism includes a first-level lifting cylinder and a first-level lifting plate. The first-level lifting cylinder is installed on the table panel, and the first-level lifting plate is located between the table panel and the base plate. The output end of the first-level lifting cylinder passes through the table panel and is connected to the first-level lifting plate.

[0015] In some embodiments, a bearing seat is provided on the secondary lifting plate, and the rotating column is rotatably connected to the secondary lifting plate through the bearing seat.

[0016] In some embodiments, the rotation drive mechanism includes a motor and a reducer. The motor drives the rotating column through the reducer. The output end of the reducer is connected to the torque sensor, and the reducer is connected to the secondary lifting plate via a connecting rod. The reducer is a worm gear reducer, and the motor is mounted on the side of the reducer.

[0017] In some embodiments, a clamping mechanism is provided on the base plate, and the clamping mechanism is used to press the product tooling on the base plate.

After the line tooling reaches the torque detection position under the conveyor mechanism, the first-level lifting mechanism lifts the line tooling as a whole, allowing it to separate from the conveyor mechanism. Next, the second-level lifting mechanism lifts the torque testing mechanism, which in turn lifts the product tooling on the base plate. At this point, the torque testing mechanism is connected to the product tooling. The torque testing mechanism is used to rotate the product tooling. Because the anti-rotation mechanism restricts the rotation of the steering knuckle, the product tooling will drive the brake disc to rotate, and the starting torque of the steering knuckle assembly can be measured. This enables the detection of starting torque on the production line without the need to flip the steering knuckle assembly 180°.

DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0036] like Figure 1 As shown, the utility model provides an online detection mechanism for the starting torque of the brake disc of the steering knuckle assembly, comprising:

[0037] Table panel 1, on which a conveying mechanism 11, a beam photoelectric sensor 12, and a blocking cylinder 13 are provided. The conveying mechanism 11 adopts a double-speed chain conveyor line, the beam photoelectric sensor 12 is used to detect the presence of products, and the blocking cylinder 13 is used to block the line tooling 2;

[0038] Line tooling 2, such as Figure 5 As shown, the line tooling 2 includes a base plate 21, which is arranged on the conveying mechanism 11. The conveying mechanism 11 is used to convey the line tooling 2 to the torque detection position. After the blocking cylinder 13 blocks the line tooling 2, the line tooling 2 is located at the torque detection position. A product tooling 22 and an anti-rotation mechanism 23 are set on the base plate 21. The product tooling 22 is used to place products. The anti-rotation mechanism 23 is used to limit the rotation of the steering knuckle. The anti-rotation mechanism 23 includes a bracket and a rotating block. The bracket is fixed on the base plate 21. One end of the rotating block is rotatably connected to the bracket, and the other end of the rotating block is rotatably connected to the steering knuckle. Since the bracket is fixed to the base plate 21, the steering knuckle cannot rotate.

[0039] The torque testing mechanism 5 is used to cooperate with the product tooling 22 to drive the brake disc of the steering knuckle assembly 6 to rotate, thereby detecting the starting torque;

[0040] A first-level lifting mechanism 3 is provided on the table panel 1 and is used to lift the bottom plate 21 so that the line tooling 2 is separated from the conveying mechanism 11;

[0041] The secondary lifting mechanism 4 is used to lift the torque testing mechanism 5 and the product tooling 22 so that the torque testing mechanism 5 and the product tooling 22 can be matched.

[0042] It can be understood that the steering knuckle assembly 6 can be placed on the product tooling 22 in advance, and the rotation of the steering knuckle can be limited by the anti-rotation mechanism 23. After the line tooling 2 reaches the torque detection position under the transportation of the conveying mechanism 11, the first-level lifting mechanism 3 lifts the line tooling 2 as a whole, so that the line tooling 2 is separated from the conveying mechanism 11. Then, the second-level lifting mechanism 4 lifts the torque testing mechanism 5, and the torque testing mechanism 5 lifts the product tooling 22 on the bottom plate 21. At this time, the torque testing mechanism 5 is connected to the product tooling 22, and the torque testing mechanism 5 is used to rotate the product tooling 22. Since the anti-rotation mechanism 23 limits the rotation of the steering knuckle, the product tooling 22 will drive the brake disc to rotate, and the starting torque of the steering knuckle assembly 6 can be measured.

[0043] In some embodiments, as Figure 5 、 7 As shown, the product tooling 22 includes a positioning seat 221, such as Figure 8 As shown, the positioning seat 221 is mounted on the base plate 21 through the first positioning pin 224, that is, the positioning seat 221 is directly placed on the base plate 21 and is limited in horizontal movement by the positioning pin, as shown in FIG. Figure 7As shown, a positioning hole 222 and a connecting hole 223 are provided in the positioning seat 221. The positioning hole 222 is located at the upper part of the positioning seat 221, and the connecting hole 223 is located at the lower part of the positioning seat 221. The positioning hole 222 is used to cooperate with the brake disc. A first pin hole is provided on the lower end surface of the positioning seat 221. The static friction force between the positioning seat 221 and the brake disc is greater than the starting torque of the steering knuckle assembly 6; the positioning seat 221 cooperates with the torque testing mechanism 5 through the connecting hole 223 and the first pin hole, so that the torque testing mechanism 5 can drive the positioning seat 221 to rotate.

[0044] It can be understood that the torque testing mechanism 5 drives the positioning seat 221 to rotate, and the static friction between the positioning seat 221 and the brake disc is greater than the starting torque of the steering knuckle assembly 6. Rotating the positioning seat 221 can drive the brake disc to rotate, thereby measuring the starting torque.

[0045] In some embodiments, as Figure 9 As shown, the first-level lifting mechanism 3 includes a first-level lifting cylinder 31 and a first-level lifting plate 32. The first-level lifting cylinder 31 is installed on the table panel 1. The first-level lifting plate 32 is located between the table panel 1 and the base plate 21. A hole is opened in the middle of the first-level lifting plate 32 for the torque testing mechanism 5 to pass through. The output end of the first-level lifting cylinder 31 passes through the table panel 1 and is connected to the first-level lifting plate 32. The first-level lifting plate 32 cooperates with the base plate 21 through the first-level lifting positioning pin 34. The first-level lifting positioning pin 34 includes a cylindrical pin and a prismatic pin.

[0046] In some embodiments, as Figure 9 As shown, the first-level lifting mechanism 3 also includes a first-level lifting guide rod 33. The outer shell of the first-level lifting guide rod 33 is fixed on the table panel 1. The telescopic rod of the first-level lifting guide rod 33 passes through the table panel 1 and is connected to the first-level lifting plate 32. The first-level lifting guide rod 33 is used to guide the precise fit between the first-level lifting plate 32 and the base plate 21.

[0047] In some embodiments, as Figure 10 As shown, a support frame 14 is set under the table panel 1, and the support frame 14 is connected to the table panel 1 through four columns 15. The secondary jacking mechanism 4 includes a secondary jacking cylinder 41 and a secondary jacking plate 42. The secondary jacking cylinder 41 is installed on the lower surface of the support frame 14, and the output end of the secondary jacking cylinder 41 passes through the support frame 14 and is connected to the secondary jacking plate 42. The torque testing mechanism 5 is installed on the secondary jacking plate 42.

[0048] It can be understood that the secondary lifting cylinder 41 can lift the secondary lifting plate 42 upward relative to the table panel 1, and the secondary lifting plate 42 drives the entire torque testing mechanism 5 to move upward until the top of the torque testing mechanism 5 is connected to the product tooling 22, at which time the torque detection can be started.

[0049] In some embodiments, as Figure 10As shown, the secondary lifting mechanism 4 also includes a secondary lifting guide rod 43. The outer shell of the secondary lifting guide rod 43 is fixed on the support frame 14. The telescopic rod of the secondary lifting guide rod 43 passes through the support frame 14 and is connected to the secondary lifting plate 42. The secondary lifting guide rod 43 is used to guide the precise matching of the torque testing mechanism 5 and the product tooling 22.

[0050] In some embodiments, as Figure 10 、 11 As shown, the torque testing mechanism 5 includes a rotation drive mechanism, a torque sensor 54, and a rotating column 56 connected in sequence. A connecting head 561 and a connecting pin 562 are set on the top of the rotating column 56. The connecting head 561 is annular and is used to be inserted into the connecting hole 223. The connecting pin 562 is used to cooperate with the first pin hole opened on the lower end surface of the positioning seat 221.

[0051] In some embodiments, as Figure 11 As shown, the rotation drive mechanism and the torque sensor 54 are connected via a diaphragm coupling 53 , and the torque sensor 54 and the rotation column 56 are connected via a rigid coupling 55 .

[0052] The diaphragm coupling 53 and the rigid coupling 55 are advantageous for improving the detection accuracy. The diaphragm coupling 53 has high torsional rigidity, zero rotation and long service life.

[0053] In some embodiments, as Figure 11 As shown, a bearing seat 44 is provided on the secondary lifting plate 42 , and the rotating column 56 is rotatably connected to the secondary lifting plate 42 through the bearing seat 44 .

[0054] In some embodiments, as Figure 10 As shown, the rotation drive mechanism includes a motor 51 and a reducer 52. The motor 51 drives the rotating column 56 through the reducer 52. The output end of the reducer 52 is connected to the torque sensor 54. The reducer 52 is connected to the secondary lifting plate 42 via a connecting rod to ensure stable lifting of the torque testing mechanism 5. The reducer 52 is a worm gear reducer, and the motor 51 is installed on the side of the reducer 52.

[0055] In some embodiments, as Figure 7 、 8 As shown, a pressing mechanism 24 is provided on the bottom plate 21, and the pressing mechanism 24 is used to press the product tooling 22 onto the bottom plate 21, as shown in FIG. Figure 4 、 9As shown, the first-stage lifting mechanism 3 is provided with an unlocking mechanism for releasing the lock on the product tooling 22 by the clamping mechanism 24, allowing the second-stage lifting mechanism 4 to lift the product tooling 22. The clamping mechanism 24 ensures the stability of the product tooling 22 during transportation. The unlocking mechanism releases the lock on the product tooling 22 by the clamping mechanism 24, allowing the torque testing mechanism 5 to lift the product tooling 22.

[0056] In some embodiments, as Figure 8 As shown, the clamping mechanism 24 includes a clamping seat 241, a clamping block 242 is rotatably arranged in the clamping seat 241, a clamping spring 243 is arranged in the clamping seat 241, and the clamping spring 243 is used to press the clamping block 242 onto the product tooling 22, and the unlocking mechanism includes an unlocking cylinder 35, which is installed on the first-stage lifting mechanism 3, and the unlocking cylinder 35 is used to drive the clamping block 242 to rotate to release the restriction on the product tooling 22.

[0057] In some embodiments, a side surface of the pressing block 242 is provided with a pressing extension 244 and a rotating extension 245, which are arranged at the upper and lower portions of the pressing block 242, respectively. A pressing spring 243 is connected to the upper portion of the pressing block 242. Under the action of the pressing spring 243, the pressing extension 244 presses against the product fixture 22. The rotating extension 245 cooperates with the unlocking cylinder 35 to enable the pressing block 242 to release the restraint on the product fixture 22. In other words, under the action of the pressing spring 243, the pressing block 242 tends to rotate clockwise, causing the pressing extension 244 to press against the product fixture 22. When the output end of the unlocking cylinder 35 extends, the unlocking cylinder 35 applies a pushing force to the rotating extension 245, causing the pressing block 242 to rotate counterclockwise, thereby releasing the restraint on the product fixture 22 and enabling the detection of the starting torque.

[0058] The working principle of the online detection mechanism of the steering knuckle assembly brake disc starting torque is as follows:

[0059] After the steering knuckle assembly 6 is assembled, the steering knuckle assembly 6 is placed on the product tooling 22 in advance, and the anti-rotation mechanism 23 is manually connected to the steering knuckle at the top of the steering knuckle assembly 6 to prevent the steering knuckle from rotating;

[0060] After the line tooling 2 is transported to the torque detection position, it is blocked by the blocking cylinder 13. The photoelectric sensor 12 detects the steering knuckle assembly 6 and starts the torque detection.

[0061] The first-stage lifting cylinder 31 lifts the first-stage lifting plate 32 upward to a preset position. The first-stage lifting plate 32 lifts the entire line tooling 2, so that the line tooling 2 is separated from the conveying mechanism 11. The first-stage lifting plate 32 limits the bottom plate 21 of the line tooling 2 through the first-stage lifting positioning pin 34;

[0062] The unlocking cylinder 35 drives the pressing block 242 to rotate, so that the pressing block 242 releases the restriction on the product tooling 22;

[0063] The secondary lifting cylinder 41 lifts the secondary lifting plate 42 upward to a preset position. The torque testing mechanism 5 rises to the preset position together with the secondary lifting plate 42, so that the connecting head 561 of the rotating column 56 is inserted into the connecting hole 223 of the positioning seat 221, and the connecting pin 562 is inserted into the first pin hole of the positioning seat 221. The product tooling 22 and the steering knuckle assembly 6 on the product tooling 22 are lifted, and the product tooling 22 is separated from the base plate 21.

[0064] The starting motor 51 drives the brake disc to rotate 360° through the rotating column 56. The maximum torque during the 360° rotation is the starting torque value, which is obtained by the calibrated torque sensor 54.

[0065] After the inspection is completed, the second-level lifting cylinder 41 is reset, so that the product tooling 22 is placed back on the base plate 21, the unlocking cylinder 35 is retracted, the clamping block 242 re-fixes the product tooling 22, and the first-level lifting cylinder 31 is reset, so that the line tooling 2 is placed back on the conveying mechanism 11, the blocking cylinder 13 descends, and the line tooling 2 moves to the next workstation.

[0066] The utility model realizes the detection of the starting torque on the production line without the need to flip the steering knuckle assembly 6 180 degrees.

[0067] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
