Description

Technical Field

[0001] The present invention relates to the technical field of laser measuring devices, and in particular to a fully automatic laser measuring device and method for automobile wheel hub aperture size. Background Art

[0002] After the automobile wheel hub is produced, a fully automated laser measuring device is required to use a line laser to scan the wheel hub surface, then generate the wheel hub data, and then calculate parameters such as the wheel hub aperture diameter.

[0003] The Chinese patent application with authorization announcement number CN215296155U discloses an aluminum alloy wheel hub size detection device. The gantry is fixed to the base. The large end and small end of the stepped cylinder in the above-mentioned prior art are respectively equipped with laser source A and laser source B. The stepped cylinder can rotate around itself and drive laser source A and laser source B to rotate synchronously to detect apertures of different diameters.

[0004] In the above-mentioned prior art, the wheel hub is fixed by a limit device and then inspected by a laser measuring device. However, in a large production line, when the wheel hub is quickly transported to the bottom of the laser measuring device by a roller conveyor, the wheel hub may slightly deviate from the center below the laser measuring device due to its own inertia, resulting in inaccurate aperture measurement by the laser measuring device.

[0026] A fully automated laser measurement method for automobile wheel hub aperture size, using the above-mentioned fully automated laser measurement device for automobile wheel hub aperture size, comprises the following steps:

[0027] S1. The wheel hub is transported to the roller conveyor on the production line and first contacts the runner. The elasticity of the clamping assembly mobilizes the runner to clamp the wheel hub firmly. The movement of the runner drives the air in the clamping assembly to be transported into cylinder 3, pushing piston shaft 1 to adjust the position of the blocking part.

[0028] S2, the wheel hub then contacts the blocking wheel and pushes it to move. When the wheel passes the two end points of the hub diameter, it will reset a certain distance. At this time, the air intake in the cylinder 3 stops and the position of the blocking part is fixed;

[0029] S3. Plate 2 then presses the triangular block downward, driving the telescopic blocking portion to descend within the inner cavity of tube 2, blocking the connection between tube 2 and the telescopic hose, preventing air from entering the inner cavity of tube 3. Plate 2 is then blocked by the blocking portion, and the retaining wheel stops moving. At this point, the center of the wheel hub is directly below the laser measuring device, and the laser measuring device is then used to measure the diameter of the wheel hub.

[0030] S4. During the measurement process, in order to ensure that the laser measuring equipment uses the laser to accurately measure the aperture of the wheel hub, the wheel rotates to drive the wheel hub to rotate. If the wheel hub is deformed, the wheel will drive the clamping assembly to move slightly, and then the marking mechanism will apply paint to the deformed part of the wheel hub through the wheel.

[0031] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0032] The roller conveyor transports the hub on the production line to the rotating wheel. When the rotating wheel is pushed by the hub, it drives the piston shaft 2 to move in the direction of spring 4, thereby transporting the air in the inner cavity of cylinder 1 to the inner cavity of cylinder 2 through the air outlet pipe 1, and enters cylinder 3 along the telescopic hose, thereby pushing the piston shaft 1 to move in the inner cavity of cylinder 3, and then pushing the blocking part to move. When the rotating wheel passes the two end points of the hub diameter, the elasticity of spring 4 drives the rotating wheel to move a distance along the surface of the hub toward the center of the bracket. At this time, only the air outlet pipe 1 is connected with the inner cavity of cylinder 2, so no air enters the inner cavity of cylinder 3, so the blocking part stops moving. At the same time, the hub pushes the resisting wheel to move. After the resisting wheel drives plate 2 to press the triangle block downward, it is blocked by the blocking part, and the resisting wheel stops moving to position the hub.

[0033] Thereby, the position of the retaining wheel is adjusted according to the size of the wheel hub. When the wheel hub is larger, the distance the retaining wheel is pushed is longer, and when the wheel hub is smaller, the distance the retaining wheel is pushed is shorter, so that the retaining wheel and the rotating wheel can limit and lock the wheel hubs of different sizes. Moreover, through the blocking of the retaining wheel, it is ensured that the centers of wheel hubs of different sizes can be aligned directly below the laser measuring equipment, thereby avoiding the displacement of the center of the wheel hub due to its own inertia when the wheel hub is transported on the roller conveyor.

[0034] When the triangular block is pressed down, the telescopic blocking part is driven to descend in the inner cavity of the tube 2 through the round rod 1 and the slide groove part, and the telescopic blocking part passes over the air outlet pipe 1 and the air outlet pipe 2 to block the connection between the telescopic hose and the tube 2, so that the air outlet pipe 1, the air outlet pipe 2, the tube 2 and the tube 4 are connected; then the liquid inlet pipe is started to drive the rotating wheel to rotate, so that the wheel hub rotates, ensuring that the laser measuring equipment can accurately and comprehensively measure the aperture of the wheel hub, and when the conical column on the rotating wheel contacts the wheel hub, it will be squeezed into the liquid outlet tank by the wheel hub.

[0035] When the wheel hub is deformed before measurement, the deformed part of the wheel hub will contact the runner, and due to the deformation of the wheel hub, the runner elastically squeezed by the spring four will move, thereby driving the piston shaft two to move in the inner cavity of the cylinder one, thereby squeezing the air in the inner cavity of the cylinder one into the cylinder four through the cylinder two, and the piston shaft three squeezes the paint in the inner cavity of the cylinder four into the plate three along the liquid outlet pipe. The plate three rises due to the squeezing of the liquid, thereby allowing the paint to enter the inner cavity of the runner from the circular hole of the perforated plate, and then squeeze into the deformed part of the wheel hub through the liquid outlet groove, thereby achieving the goal of applying the paint to the deformed part of the wheel hub when the runner contacts the deformed part of the wheel hub, which is convenient for the subsequent staff to quickly check, and check the data of the hub diameter measured by the laser measuring equipment to know whether the deformation affects the aperture.

[0063] In the initial state, the telescopic blocking portion 19 is located at the top end of the inner cavity of the second tube 8. At this time, the connection between the second outlet pipe 7 and the fourth tube 26 and the second tube 8 is blocked by the telescopic blocking portion 19.

[0064] When the two wheels 30 pass the two end points of the diameter, the triangular block 15 is pressed down by the wheel hub, thereby driving the telescopic blocking part 19 to descend in the inner cavity of the second tube 8 through the round rod 16 and the slide groove part 17 to block the connection between the telescopic hose 9 and the second tube 8.

[0067] The top of the blocking portion 13 is L-shaped. After the second plate 25 presses the triangular block 15 downward, it contacts the L-shaped top of the blocking portion 13, so that the second plate 25 is blocked by the blocking portion 13 and no longer moves forward.

[0068] Also includes a plate 20 and a driving device 21;

[0069] The upper part of the bracket 1 is C-shaped, and the blocking component is located at the notch of the bracket 1; a through hole is opened on the cylinder three 10, and the plate 1 20 is installed on the bracket 1 to block the through hole; a driving device 1 21 for driving the cylinder three 10 to rise and fall is installed at the bottom of the bracket 1. When the cylinder three 10 descends, the plate 1 20 is separated from the through hole.

[0070] Plate 1 20 is separated from the through hole, and the air in the inner cavity of cylinder 3 10 is discharged through the through hole. After the wheel hub is measured by the laser measuring device 3, the driving device 1 21 is started to drive cylinder 3 10 to descend, and then drive the resisting wheel 24 and the blocking part 13 to descend. At this time, the telescopic rod 1 of the telescopic blocking part 19 is used to prevent the telescopic blocking part 19 from being affected.

[0071] The air inlet pipe 5 is composed of a circular pipe 1 and a one-way air inlet valve, the air outlet pipe 1 6 and the air outlet pipe 2 7 are composed of a circular pipe 2 and a one-way air outlet valve; the liquid outlet pipe 28 is composed of a hose and a one-way liquid outlet valve, and the liquid inlet pipe 29 is composed of a circular pipe 3 and a one-way liquid inlet valve.

[0072] Example 2, as in 1- Figure 12 As shown, the fully automated laser measuring device for automobile wheel hub aperture size proposed by the present invention comprises a fourth cylinder 26, a third spring 27, a liquid outlet pipe 28, a liquid inlet pipe 29, a control valve 40, a third piston shaft 41 and a marking assembly compared to the first embodiment;

[0073] Cylinder four 26 is connected to cylinder two 8, one end of spring three 27 is installed in cylinder four 26, and the other end of spring three 27 is connected to piston shaft three 41, which is movably sleeved in cylinder four 26; cylinder four 26 is connected to control valve 40; cylinder four 26 is connected to liquid inlet pipe 29; one end of liquid outlet pipe 28 is connected to cylinder four 26, and the other end of liquid outlet pipe 28 is movably connected to runner 30; the marking assembly is installed in runner 30; when runner 30 contacts the deformed part of the hub, it drives the clamping assembly to move, and delivers air into cylinder four 26, and piston shaft three 41 squeezes the paint into runner 30, and then the paint is applied to the deformed part of the hub through the marking assembly.

[0074] The marking assembly includes an elastic member 1 31, a plate 32, a perforated plate 33, a liquid outlet trough 34, an elastic member 2 35, and a tapered column 36;

[0075] The liquid outlet groove 34 is provided in the runner 30; the liquid outlet pipe 28 is connected to the liquid outlet groove 34; one end of the elastic member 1 31 is installed in the middle of the inner cavity of the runner 30, and the other end thereof is connected to the plate 32, the perforated plate 33 is installed at the connection between the runner 30 and the liquid inlet pipe 29, and the plate 32 is pressed against the perforated plate 33 by the elasticity of the elastic member 1 31; one end of the elastic member 2 35 is installed in the liquid outlet groove 34, and the other end thereof is connected to the tapered column 36; the tapered column 36 is in contact with the wheel hub and is squeezed into the runner 30 by the wheel hub, so that the liquid outlet groove 34 is connected to the outside world. At this time, the paint is discharged from the liquid outlet groove 34 to the deformation point of the wheel hub.

[0076] In the initial state, the liquid outlet groove 34 is also filled with paint, but the paint is not full. When the wheel hub is not deformed, the conical column 36 is pushed into the inner cavity of the liquid outlet groove 34 by the wheel hub. Since there is less paint and the inner cavity of the liquid outlet groove 34 is in a negative pressure state, the paint will not be discharged.

[0077] The other end of liquid inlet tube 29 is connected to the paint supply pipe. Paint flows through liquid inlet tube 29 into the interior of barrel 26 and is located at the portion of piston shaft 3 41 that is distal to control valve 40. When piston shaft 3 41 reaches its maximum distance during subsequent use, control valve 40 is activated to expel air from barrel 26. At this point, the elasticity of spring 3 27 forces piston shaft 3 41 to return to its original position, allowing paint to be replenished into barrel 26.

[0078] The first driving device 21 is a cylinder, and the second driving device 39 is a servo motor.

[0079] Example 3, as Figures 1-12 As shown, the present invention proposes a fully automated laser measurement method for automobile wheel hub aperture size, which uses a fully automated laser measurement device for automobile wheel hub aperture size in embodiment 1, and includes the following steps:

[0080] S1. The wheel hub is transported to the roller conveyor 2 on the production line. It first contacts the runner 30. The elasticity of the clamping assembly mobilizes the runner 30 to clamp the wheel hub. The movement of the runner 30 drives the air in the clamping assembly into the cylinder 3 10, pushing the piston shaft 1 12 to adjust the position of the blocking part 13.

[0081] S2, the wheel hub then contacts the blocking wheel 24 and pushes the blocking wheel 24 to move. When the rotating wheel 30 passes the two end points of the wheel hub diameter, it will reset a distance. At this time, the air intake in the cylinder 10 stops and the position of the blocking part 13 is fixed;

[0082] S3. Then, the second plate 25 presses the triangular block 15 downward, driving the telescopic blocking portion 19 to descend into the inner cavity of the second cylinder 8, blocking the connection between the second cylinder 8 and the telescopic hose 9, so that air cannot enter the inner cavity of the third cylinder 10. Then, the second plate 25 is blocked by the blocking portion 13, and the blocking wheel 24 stops moving. At this time, the center of the wheel hub is directly below the laser measuring device 3. Then, the laser measuring device 3 uses a laser to measure the aperture of the wheel hub;

[0083] S4. During the measurement process, in order to ensure that the laser measuring device 3 accurately measures the aperture of the wheel hub using the laser, the wheel 30 rotates to drive the wheel hub to rotate. If the wheel hub is deformed, the wheel 30 will drive the clamping assembly to move slightly, and then the marking mechanism will apply paint to the deformed part of the wheel hub through the wheel 30.

[0084] In summary, in the present invention, the wheel hub is conveyed between the two rotating wheels 30 by the roller conveyor 2, thereby conveying the two rotating wheels 30 toward the direction of cylinder 1 4, thereby driving the piston shaft 2 38 in the inner cavity of cylinder 1 4 to push toward the inner cavity of spring 4 37, thereby conveying the air in the inner cavity of cylinder 1 4 along the air outlet pipe 1 6 to the inner cavity of cylinder 2 8, and conveying it to the inner cavity of cylinder 3 10 through the telescopic hose 9, pushing the piston shaft 12 to move in the inner cavity of cylinder 3 10, thereby driving the blocking part 13 to move.

[0085] At the same time, the wheel hub contacts the resisting wheel 24 and pushes the resisting wheel 24 to move toward the triangular block 15. When the two rotating wheels 30 pass the two end points of the wheel hub diameter, the elasticity of the spring four 37 drives the rotating wheel 30 to move a distance toward the center of the bracket 1, so that the air in the inner cavity of the cylinder one 4 no longer enters the cylinder three 10, and the piston shaft one 12 no longer moves. At this time, the wheel hub pushes the resisting wheel 24 so that the plate two 25 presses the triangular block 15 downward, and the plate two 25 is blocked by the blocking part 13, so that the wheel hub and the resisting wheel 24 both stop moving. At this time, the center of the wheel hub is positioned directly below the laser measuring device 3.

[0086] When the triangular block 15 is pressed, the round rod 16 and the chute portion 17 are driven to descend, and then the chute portion 17 drives the telescopic blocking portion 19 to descend, and the telescopic blocking portion 19 passes over the outlet pipe 1 6 and the outlet pipe 2 7 to block the connection between the cylinder 2 8 and the telescopic hose 9. At this time, the two wheels 30 cooperate with the blocking wheel 24 to clamp the wheel hub. Figure 12 shown.

[0087] And because the distance moved by the blocking portion 13 is proportional to the longest distance moved by the wheel 30, when the hub is larger, the distance the wheel 30 is pushed away is longer, so the distance moved by the blocking portion 13 is longer, and the timing when the blocking wheel 24 is blocked from moving is later, thereby ensuring that the centers of hubs of different sizes are located directly below the laser measuring device 3.

[0088] Then, the aperture of the wheel hub is measured by the laser measuring device 3. At the same time, since the laser measuring device 3 is fixed, in order for the laser measuring device 3 to accurately measure the aperture of the wheel hub in all directions, the driving device 2 39 is started to drive the wheel 30 to rotate, and the rotation of the wheel 30 drives the wheel hub to rotate.

[0089] If the wheel hub is stacked and placed before measurement, causing the wheel hub to deform, these deformations may affect the accuracy of the wheel hub aperture value.

[0090] When the runner 30 contacts the deformed part of the hub, the deformed part of the hub may be concave or convex, which will cause the runner 30 to move. When the runner 30 drives the piston shaft 2 38 to move in the inner cavity of the cylinder 1 4, the air in the inner cavity of the cylinder 1 4 is squeezed into the cylinder 2 8 through the air outlet pipe 1 6 or the air outlet pipe 2 7. Since the connection between the cylinder 2 8 and the telescopic hose 9 is blocked by the telescopic blocking part 19 at this time, the air entering the inner cavity of the cylinder 2 8 enters the cylinder 4 26, thereby pushing the piston shaft 3 41 to move in the inner cavity of the cylinder 4 26, and then pushing the paint in the inner cavity of the cylinder 4 26 into the liquid outlet pipe 28. At this time, the paint in the inner cavity of the liquid outlet pipe 28 squeezes the plate 3 32, pushing the plate 3 32 upward, so that the paint passes through the circular hole of the perforated plate 33 and enters the liquid outlet tank 34.

[0091] When the wheel 30 contacts the hub, the conical column 36 is pressed into the liquid outlet groove 34 by the hub, thereby making the liquid outlet groove 34 connected to the outside. At this time, paint enters the liquid outlet groove 34, and then the paint is discharged through the liquid outlet groove 34 to the deformation part of the hub, thereby marking the deformation part of the hub. The other conical columns 36 that are not in contact with the hub will not be pushed, so the paint will not be discharged.

[0092] After the laser measuring device 3 completes the measurement, the driving device 1 21 is started to drive the drum 3 10 to descend, thereby driving the resisting wheel 24 and the blocking part 13 to descend, and then the roller conveyor 2 can transport the wheel hub.

[0093] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
