[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] Please see Figures 1 to 5 According to an embodiment of the present invention, a chain conveyor for a stabilizer bar tempering furnace includes a conveyor chain transmission mechanism 1, a feeding chain transmission mechanism 2, a first detection mechanism, a second detection mechanism, a first blocking mechanism 41, a second blocking mechanism 42, a centering mechanism 5, and a control device.

[0017] The conveyor chain conveyor mechanism 1 is located between the stabilizer bar tempering furnace (not shown in the figure) and the feeding chain conveyor mechanism 2, and is used to receive the stabilizer bar output from the stabilizer bar tempering furnace.

[0018] In this embodiment, the conveyor chain transmission mechanism 1 includes a first driving sprocket shaft 11, a pair of first driven sprocket shafts 12, a pair of first supports 13, a pair of first closed-loop chains 14, a pair of first driving sprockets 15, a pair of first driven sprockets 16, and a first drive mechanism.

[0019] A first drive sprocket shaft 11 and a pair of first driven sprocket shafts 12 are respectively mounted on a pair of first supports 13. A pair of first drive sprockets 15 are mounted on the first drive sprocket shaft 11 and are located on both sides of the pair of first supports 13. A pair of first driven sprockets 16 are respectively mounted on the pair of first driven sprocket shafts 12 and are located on both sides of the pair of first supports 13. One first closed-loop chain 14 is wound around the first drive sprocket 15 and the first driven sprocket 16 located on one side of the pair of first supports 13, and the other first closed-loop chain 14 is wound around the first drive sprocket 15 and the first driven sprocket 16 located on the other side of the pair of first supports 13. A first drive mechanism is used to drive the first drive sprocket shaft 11 to rotate, so as to drive the pair of first drive sprockets 15 to rotate synchronously. The first drive mechanism includes a first drive motor 171 and a first transmission mechanism for transmitting the output torque of the first drive motor 171 to the first drive sprocket shaft 11.

[0020] Furthermore, the conveyor chain mechanism 1 includes a first base 18 and a first spacing adjustment mechanism. A pair of first supports 13 are mounted on the first base 18 in a manner that allows them to slide along a conveying direction perpendicular to the conveyor chain mechanism 1. Specifically, the first base 18 is provided with a pair of first guide rails 181 extending along a conveying direction perpendicular to the conveyor chain mechanism 1, and the bottom of each first support 13 is provided with a pair of first sliders 131 that are slidably engaged with the pair of first guide rails 181. The first spacing adjustment mechanism is used to drive the pair of first supports 13 to move towards or away from each other, thereby reducing or increasing the spacing between the pair of first supports 13. The first spacing adjustment mechanism includes a first lead screw 191 and a first handle 192 connected to the first lead screw 191. The pair of first supports 13 are helically connected to the first lead screw 191. By rotating the first handle 192 clockwise or counterclockwise, the pair of first supports 13 can be driven to move towards or away from each other. By adjusting the spacing between the first supports 13, the conveyor chain mechanism 1 can be adapted to conveying stabilizer bars of different sizes, thus broadening the application range of the conveyor chain mechanism 1.

[0021] The conveying direction of the feeding chain conveyor 2 is the same as that of the conveying chain conveyor 1. The conveying surface of the feeding chain conveyor 2 is lower than that of the conveying surface of the conveying chain conveyor 1 to support the stabilizing rod 9 conveyed by the conveying chain conveyor 1.

[0022] The feeding chain conveyor 2 includes the second driving sprocket shaft 21, a pair of second driven sprocket shafts 22, a pair of second supports 23, a pair of second closed-loop chains 24, a pair of second driving sprockets 25, a pair of second driven sprockets 26, and a second drive mechanism.

[0023] A second drive sprocket shaft 21 and a pair of second driven sprocket shafts 22 are respectively mounted on a pair of second brackets 23. A pair of second drive sprockets 25 are mounted on the second drive sprocket shaft 21 and are located on both sides of the pair of second brackets 23. A pair of second driven sprockets 26 are respectively mounted on the pair of second driven sprocket shafts 22 and are located on both sides of the pair of second brackets 23. One second closed-loop chain 24 is wound around the second drive sprocket 25 and the second driven sprocket 26 located on one side of the pair of second brackets 23, and the other second closed-loop chain 24 is wound around the second drive sprocket 25 and the second driven sprocket 26 located on the other side of the pair of second brackets 23. A second drive mechanism is used to drive the second drive sprocket shaft 21 to rotate, thereby driving the pair of second drive sprockets 25 to rotate synchronously. The second drive mechanism includes a second drive motor 271 and a second transmission mechanism for transmitting the output torque of the second drive motor 271 to the second drive sprocket shaft 21.

[0024] Furthermore, the feeding chain conveyor 2 includes a second base 28 and a second spacing adjustment mechanism. A pair of second supports 23 are mounted on the second base 28 in a manner that allows them to slide along a direction perpendicular to the conveying direction of the feeding chain conveyor 2. Specifically, the second base 28 is provided with a pair of second guide rails 281 extending along a direction perpendicular to the conveying direction of the feeding chain conveyor 2, and the bottom of each second support 23 is provided with a pair of second sliders 231 that are slidably engaged with the pair of second guide rails 281. The second spacing adjustment mechanism is used to drive the pair of second supports 23 to move towards or away from each other, thereby reducing or increasing the spacing between the pair of second supports 23. The second spacing adjustment mechanism includes a second lead screw 291 and a second handle 292 connected to the second lead screw 291. The pair of second supports 23 are helically connected to the second lead screw 291. By rotating the second handle 292 clockwise or counterclockwise, the pair of second supports 23 can be driven to move towards or away from each other. By adjusting the spacing between the second supports 23, the feeding chain conveyor 2 can be adapted to conveying stabilizer bars of different sizes, thus broadening the application range of the feeding chain conveyor 2.

[0025] Furthermore, multiple pairs of stabilizer bar supports 241 are evenly spaced along the conveying direction on a pair of second closed-loop chains 24. Each pair of stabilizer bar supports 241 is respectively arranged opposite to each other on a pair of second closed-loop chains 24, and the top surface of each stabilizer bar support 241 has a groove 242 for accommodating the stabilizer bar body. The stabilizer bar supports 241 support the stabilizer bar 9, facilitating subsequent gripping of the stabilizer bar 9 by the robot arm.

[0026] The first detection mechanism is used to detect whether there is material at the discharge end of the conveyor chain 1, and sends the detection result to the control device. In this embodiment, the first detection mechanism includes a first proximity switch 31, which is installed on the inner side of the first bracket 13.

[0027] The second detection mechanism is used to detect whether there is material at the discharge end of the feeding chain conveyor 2, and sends the detection result to the control device. In this embodiment, the second detection mechanism includes a second proximity switch 32, which is installed on the inner side of the second bracket 23.

[0028] The first blocking mechanism 41 is located between the feed end and the discharge end of the conveyor chain mechanism 1 to prevent the stabilizer bar 9 from being conveyed forward; the second blocking mechanism 42 is located at the discharge end of the conveyor chain mechanism 1 to prevent the stabilizer bar 9 from being conveyed forward.

[0029] In this embodiment, a first blocking mechanism 41 is disposed between a pair of first supports 13. The first blocking mechanism 41 includes a first stop block 411 and a first stop block lifting drive mechanism. The first stop block lifting drive mechanism is connected to the first stop block 411 to drive the first stop block 411 to move between a raised position and a lowered position. When the first stop block 411 is in the raised position, it can block the stabilizer bar 9. Optionally, the first stop block lifting drive mechanism is composed of a first cylinder 412. A second blocking mechanism 42 is disposed between a pair of second supports 23. The second blocking mechanism 42 includes a second stop block 421 and a second stop block lifting drive mechanism. The second stop block lifting drive mechanism is connected to the second stop block 421 to drive the second stop block 421 to move between a raised position and a lowered position. When the second stop block 421 is in the raised position, it can block the stabilizer bar 9. Optionally, the second stop block lifting drive mechanism is composed of a second cylinder 422.

[0030] The centering mechanism 5 is used to adjust the position of the stabilizing rod 9 that falls onto the feeding chain conveyor mechanism, so as to achieve centering of the stabilizing rod 9 with the feeding chain conveyor mechanism 2.

[0031] In this embodiment, the centering mechanism 5 includes a base 51, a pair of support seats 52, a pair of upright plates 53, a rotating plate 54, a rotating plate drive mechanism, and a pair of connecting rods 56. The pair of support seats 52 are mounted on the base 51 in a manner that allows them to slide along the conveying direction perpendicular to the feeding chain conveyor 2. Specifically, the base 51 is provided with two pairs of third guide rails 513 extending along the conveying direction perpendicular to the feeding chain conveyor 2, and the bottom of each support seat 52 is provided with a pair of third sliders 523 that respectively slide in cooperation with the corresponding pair of third guide rails 513. The pair of upright plates 53 are respectively erected on the pair of support seats 52 and are located on both sides of the feed end of the feeding chain conveyor 2. The rotating plate 54 is located between the pair of support seats 52, with the two ends of one connecting rod 56 hinged to the first side of the rotating plate 54 and one of the support seats 52, respectively, and the two ends of the other connecting rod 56 hinged to the second side of the rotating plate 54 and the other support seat 52, respectively. The first and second sides of the rotating plate 54 are opposite sides. The rotating plate drive mechanism is used to drive the rotating plate 54 to rotate around an axis perpendicular to the rotating plate 54. Optionally, the rotating plate drive mechanism is a rotary cylinder 55. The aforementioned axis perpendicular to the rotating plate 54 is the axis of the output shaft of the rotary cylinder 55, which is also the central axis of the rotating plate 54.

[0032] The control device is used to control the operation of the conveyor chain conveying mechanism 1, the feeding chain conveying mechanism 2, the first blocking mechanism 41, the second blocking mechanism 42, and the centering mechanism 5. In this embodiment, the control device is a PLC controller 6.

[0033] The working process of the stabilizer bar tempering furnace chain conveyor in this embodiment is roughly as follows.

[0034] PLC controller 6 starts the first drive motor 171, and the conveyor chain mechanism 1 begins operation. The stabilizer bar 9, having undergone tempering treatment, is fed from the stabilizer bar tempering furnace to the feed end of the conveyor chain mechanism 1. Since there is no stabilizer bar at the discharge end of the conveyor chain mechanism 1 at this time, the first proximity switch 31 does not output a signal to the PLC controller 6. Without receiving the output signal from the first proximity switch 31, the PLC controller 6 does not control the first cylinder 412 to operate; therefore, the first stop block 411 is in the lowering position, and a pair of first closed-loop chains 14 will convey the stabilizer bar 9 forward. When the stabilizer bar 9 reaches the discharge end of the conveyor chain mechanism 1, the PLC controller 6 receives the output signal from the first proximity switch 31, and then controls the push rod of the first cylinder 412 to extend upwards, raising the first stop block 411 to the raised position, preventing the subsequent conveying of stabilizer bars, and controls the second drive motor 271 to start, thus starting the feeding chain conveyor mechanism 2. Since there is no stabilizing rod at the discharge end of the feeding chain conveyor 2 at this time, the second proximity switch 32 does not output a signal to the PLC controller 6. When the PLC controller 6 does not receive the output signal from the second proximity switch 32, it will not control the second cylinder 422 to operate. Therefore, the second stop block 421 is in the descending position, and a pair of first closed-loop chains 14 will convey the stabilizing rod 9 forward until it falls into the groove 242 of the pair of stabilizing rod supports 241 of the feeding chain conveyor 2. The PLC controller 6 controls the rotary cylinder 55 to rotate clockwise, driving the pair of upright plates 53 closer together, aligning the vertical bisector of the stabilizing rod 9 with the central axis of the feeding chain conveyor 2. Subsequently, the PLC controller 6 controls the rotary cylinder 55 to rotate counterclockwise, driving the pair of upright plates 53 away from each other and resetting them. When the stabilizer bar 9 is conveyed to the discharge end of the feeding chain conveyor 2, the PLC controller 6 receives the output signal of the second proximity switch 32, and then controls the push rod of the second cylinder 422 to extend upward, causing the second stop block 421 to rise to the raised position, preventing the conveying of subsequent stabilizer bars. Subsequent stabilizer bars are conveyed in this manner. The stabilizer bar 9 conveyed to the discharge end of the feeding chain conveyor 2 is transferred by the robot to the inspection fixture for subsequent inspection processing.

[0035] The above description is a further illustration of the present invention in conjunction with specific embodiments and accompanying drawings. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can extend and deduce it according to actual use without departing from the content of the present invention. Therefore, the content of the above specific embodiments should not limit the scope of protection defined by the present invention.
