Description

Technical Field

[0001] The present invention belongs to the technical field of transmission shaft conveying devices, and in particular, relates to a transmission shaft transporting and loading device and a use method thereof. Background Art

[0002] The drive shaft is a high-speed, less-supported rotating body, so its dynamic balance is crucial; the drive shaft must be dynamically balanced before leaving the factory and adjusted on a balancing machine. For front-engine, rear-wheel drive vehicles, the drive shaft is the shaft that transmits the rotational force of the transmission to the main reducer. The drive shaft can be composed of several transmission connections, and the sections are connected by universal joints. Whether it is a new energy vehicle or a traditional vehicle, the automotive drive shaft is one of the indispensable components. With the continuous growth in demand for automobiles and the increase in labor costs, in order to improve production efficiency and capacity and reduce production costs, it is necessary to continuously improve each link of the drive shaft production process and realize automated production.

[0003] The Chinese utility model patent with patent publication number CN211309978U discloses a transmission shaft conveying mechanism; it includes a radial conveying device and an axial conveying device; the radial conveying device includes a first ramp, a first cylinder, a feeding push plate, a vertical plate and a second ramp; the axial conveying device includes a conveying roller mechanism, a second cylinder and a push rod arranged on a frame.

[0004] The above-mentioned existing transmission shaft conveying mechanism arranges the transmission shaft body to be processed in a row on the first slope. Under the action of gravity, the transmission shaft body rolls to the lower end of the first slope to the upper end of the feeding push plate, and the PLC controls the first cylinder to move upward to drive the feeding push plate to push the transmission shaft body to the upper end of the second slope. Since the feeding push plate has an inclination, when the transmission shaft body is pushed to the upper end of the second slope, it loses the obstruction of the vertical plate and slides down on the second slope. The efficient transportation of the transmission shaft before processing is achieved through a simple mechanical structure. However, in order to increase the transportation distance and prevent jamming due to a small slope, the angle is generally set larger. Such a design will cause the rolling distance of the transmission shaft to be longer, and the transmission shaft will dive at a high speed when it rolls to the lowest position of the first slope. The entire transportation process cannot effectively control the sliding speed of the transmission shaft, which is likely to cause collision between the transmission shafts. At the same time, the transmission shaft will rub against the vertical plate during the pushing process, causing wear of the transmission shaft and affecting production quality.

The control ends of the first automatic telescopic push rod, the motor, and the second automatic telescopic push rod are electrically connected to the controller respectively.

[0018] The present invention also provides a method for using a transmission shaft transport and loading device. Based on the above transmission shaft transport and loading device, the method comprises the following steps:

[0019] Step 1: Place the transmission shaft to be transported on the rubber pad in the groove. Start the motor to drive the screw to rotate. The screw drives the movable plate to move to the left during the rotation. When the first sensor on the horizontal plate detects the transmission shaft on the inclined plane, the motor stops.

[0020] Step 2: The second automatic telescopic push rod contracts to drive the transmission shaft bracket and the transmission shaft to move downward until the transmission shaft is placed on the inclined surface of the conveying bracket. Under the action of gravity, the transmission shaft rolls to the left, and then the motor drives the screw rod to rotate in the opposite direction and drives the movable plate to move to the right. When the second sensor on the vertical plate detects the right side plate, the motor stops and waits for the next transmission shaft to be conveyed;

[0021] Step 3. Move the drive shaft on the far left of the inclined plane to the top of the feeding push plate, start the extension of the first automatic telescopic push rod, and drive the feeding push plate, the blocking assembly and the drive shaft to move upward. When the feeding push plate, the blocking assembly and the drive shaft move to the upper side, the restoring force of the torsion spring drives the rotating shaft and the blocking rod to swing and tilt toward the direction close to the conveying inclined plate, and the drive shaft rolls to the left along the blocking rod and the conveying inclined plate to complete the transport and loading operation of the drive shaft.

[0022] The present invention adopts the above technical solution, which has at least the following beneficial effects:

[0023] 1. In the present invention, during the loading operation, the first automatic telescopic push rod is started to extend, driving the feeding push plate, the blocking assembly and the transmission shaft to move upward. When the feeding push plate, the blocking assembly and the transmission shaft move to the upper side, the restoring force of the torsion spring drives the rotating shaft and the blocking rod to swing and tilt in the direction close to the conveying inclined plate, and the transmission shaft rolls to the left along the blocking rod and the conveying inclined plate to complete the transportation and loading operation of the transmission shaft. Since the roller on the blocking assembly rolls along the vertical plate and the cooperation of the blocking rod can prevent the transmission shaft from rubbing against the vertical plate during the pushing process, the wear of the transmission shaft is prevented, the use effect is improved, and the overall structure is simple, which is convenient for assembly and production.

[0024] 2. The transmission shaft to be transported in the present invention is placed on the rubber pad in the groove, and then the motor is started to drive the screw to rotate. During the rotation, the screw can drive the movable plate to move to the left. When the first sensor on the horizontal plate detects the transmission shaft on the inclined surface, the motor stops, and then the second automatic telescopic push rod contracts to drive the transmission shaft bracket and the transmission shaft to move downward until the transmission shaft is placed on the inclined surface of the conveying bracket. Under the action of gravity, the transmission shaft rolls to the left, thereby shortening the rolling distance of the transmission shaft, avoiding high-speed diving, and preventing the transmission shaft from colliding during transportation, thereby improving production quality.

[0025] 3. The present invention adopts the above technical scheme, which has ingenious conception, reasonable structure and simple overall structure. It can convey and load the transmission shaft, reduce the sliding speed of the transmission shaft, prevent the transmission shaft from colliding during the conveying process, convey the transmission shaft stably, avoid friction between the transmission shaft and other components, and improve the production quality of the transmission shaft.

[0037] When in use, the right side of the conveying bracket 1 is connected to the unloading end of the drive shaft production line, and the pushing component 2 is connected to the loading end of the drive shaft production line. In the initial state, the left and right moving component 5 drives the movable plate 6 to dock on the right side of the conveying bracket 1, and the up and down moving component 7 drives the drive shaft bracket 8 to rise, so that the drive shaft bracket 8 docks at the unloading end of the drive shaft production line. The drive shaft produced on the drive shaft production line is placed on the drive shaft bracket 8, and then the up and down moving component 7 works to drive the drive shaft bracket 8 to move downward and place the drive shaft on the inclined plane 3. The drive shaft rolls on the inclined plane 3 toward the lower end of the inclined plane 3 and is arranged in a straight line on the inclined plane 3 in sequence.

[0040] In this embodiment, there are two guide rods 504, and the two guide rods 504 are arranged in parallel and spaced apart. The two ends of the guide rods 504 are respectively fixedly mounted on the left plate 501 and the right plate 502. The two guide rods 504 can improve the support and guiding effect of the movable plate 6, which is convenient to use.

[0041] A threaded hole is provided near the middle of the movable plate 6, and a screw rod 505 is threadedly connected in the threaded hole. The screw rod 505 is arranged parallel to the guide rod 504, and the two ends of the screw rod 505 are rotatably connected to the corresponding left plate 501 and right plate 502 respectively.

[0042] A motor 503 is fixedly mounted on a side surface of the right side plate 502 away from the left side plate 501 , and a power output end of the motor 503 is transmission-connected to a lead screw 505 .

[0043] The motor 503 is used to drive the screw rod 505 to rotate. The screw rod 505 is threadedly connected to the threaded hole on the movable plate 6. During the rotation process, the screw rod 505 can drive the movable plate 6 to move on the guide rod 504 through the cooperation of the threads, which is convenient to use.

[0044] In this embodiment, a switch button is installed on the right side of the conveying bracket 1, and the switch button is used to control the start and forward and reverse rotation of the motor 503. After the staff presses the switch button, the motor 503 is started to drive the screw rod 505 to rotate. During the rotation, the screw rod 505 can drive the movable plate 6 to move to the left. At this time, the guide rod 504 is used to support and guide the movement of the movable plate 6 to prevent the movable plate 6 from rotating, making the movement of the movable plate 6 more stable.

[0045] In addition to this embodiment, the left and right moving component 5 can also adopt an electric slide or a pneumatic slide. The electric slide or the pneumatic slide is the existing technology. The two ends of the electric slide or the pneumatic slide are respectively fixedly installed on the corresponding left plate 501 and the right plate 502. The sliding end of the electric slide or the pneumatic slide is fixedly connected to the lower end surface of the movable plate 6.

[0046] like Figure 2 and Figure 5 As shown, in this embodiment, the up and down moving component 7 includes a vertical plate 701 fixedly connected to the upper surface of the movable plate 6, the vertical plate 701 and the movable plate 6 are arranged vertically, and the top of the vertical plate 701 is fixedly connected to a horizontal plate 702, and the horizontal plate 702 and the movable plate 6 are arranged parallel.

[0047] At least one second automatic telescopic push rod 703 is fixedly installed on the lower surface of the transverse plate 702 , and the telescopic end of the second automatic telescopic push rod 703 passes through the transverse plate 702 and is fixedly connected to the transmission shaft bracket 8 .

[0048] In this embodiment, the number of the second automatic telescopic push rods 703 is two, and the two second automatic telescopic push rods 703 are arranged in parallel and spaced apart. The second automatic telescopic push rods 703 are used to drive the transmission shaft bracket 8 to move up and down.

[0049] In this embodiment, a plurality of reinforcing rods 704 are fixedly connected between the transverse plate 702 and the movable plate 6 , and the reinforcing rods 704 are used to improve the structural strength and stability of the vertical plate 701 and the transverse plate 702 .

[0050] With this design, when placing the drive shaft, the second automatic telescopic push rod 703 contracts to drive the drive shaft bracket 8 and the drive shaft to move downward until the drive shaft is placed on the inclined surface 3 of the conveying bracket 1. Under the action of gravity, the drive shaft rolls toward the lower end of the inclined surface 3 to prevent the drive shaft from falling directly on the inclined surface 3 and causing damage to the drive shaft, thereby achieving stable conveying of the drive shaft, improving the use effect, and avoiding collision of the drive shaft.

[0051] In this embodiment, the second automatic telescopic push rod 703 can be one of an electric push rod, a hydraulic cylinder, and a telescopic cylinder. The second automatic telescopic push rod 703 is used to drive the transmission shaft bracket 8 to move up and down.

[0052] like Figure 5 As shown, in this embodiment, a groove 801 is formed on the upper surface of the transmission shaft bracket 8 , and a rubber pad 802 is fixedly mounted on the inner wall of the groove 801 .

[0053] With such a design, the transmission shaft to be transported can be stably placed through the groove 801, and the transmission shaft can be protected by the rubber pad 802, thereby improving the transmission effect.

[0054] like Figure 2-4 and Figure 6-8 As shown, the pushing assembly 2 includes a box body 9 fixedly mounted on the left side of the conveying bracket 1, a feeding push plate 10 is arranged inside the box body 9, at least one first automatic telescopic push rod 11 is installed between the feeding push plate 10 and the inner bottom wall of the box body 9, a vertical plate 12 is fixedly mounted on the left side of the upper surface of the box body 9, a conveying inclined plate 14 is fixedly mounted on the upper end of the vertical plate 12, a blocking assembly 13 is elastically and rotatably mounted on the side of the feeding push plate 10 close to the vertical plate 12, and the blocking assembly 13 is used to block the transmission shaft when the feeding push plate 10 rises, and after the feeding push plate 10 rises to the top, the blocking assembly 13 swings and tilts in the direction close to the conveying inclined plate 14.

[0055] In this embodiment, a cavity is opened inside the box body 9 , and an upper port is arranged at the upper end of the box body 9 , and the feeding push plate 10 is movably arranged at the upper port of the box body 9 .

[0056] In this embodiment, the number of the first automatic telescopic push rods 11 is two, and the two first automatic telescopic push rods 11 are parallel and spaced apart, the mounting end of the first automatic telescopic push rod 11 is fixedly mounted on the inner bottom wall of the box body 9, and the telescopic end of the first automatic telescopic push rod 11 is fixedly connected to the feeding push plate 10.

[0057] In this design, the first automatic telescopic push rod 11 is used to drive the feeding push plate 10 to rise or fall, and the feeding push plate 10 is used to sequentially load the transmission shaft on the inclined surface 3.

[0058] In this embodiment, the first automatic telescopic push rod 11 can be one of an electric push rod, a hydraulic cylinder, and a telescopic cylinder. The first automatic telescopic push rod 11 is used to drive the feeding push plate 10 to move up and down.

[0059] like Figure 3 and Figure 6 As shown, in this embodiment, the feeding push plate 10 includes a feeding inclined plate 1001, which is arranged at the upper port of the box body 9, and the upper end surface of the feeding inclined plate 1001 is consistent with the inclination angle of the inclined surface 3 and is flush with it; a transmission shaft baffle 1002 is fixedly connected to the side of the feeding inclined plate 1001 below the conveying bracket 1, and the transmission shaft baffle 1002 is slidably installed in the box body 9. The transmission shaft baffle 1002 is used to block the transmission shaft arranged on the conveying bracket 1 after the feeding inclined plate 1001 rises.

[0060] like Figure 4 and Figure 6 As shown, in this embodiment, the blocking assembly 13 includes a plurality of blocking rods 1301 arranged on the left side of the feeding inclined plate 1001, the plurality of blocking rods 1301 are arranged in parallel and at intervals, each blocking rod 1301 is arranged at an angle, the lower end of the blocking rod 1301 is connected to the feeding inclined plate 1001 through an elastic hinge assembly, and an installation groove is provided at the top end of the blocking rod 1301, and a roller 1304 is rotatably connected to the installation groove through a pin shaft 1309.

[0061] In this embodiment, a transmission shaft placement position is set above the feeding inclined plate 1001, and the leftmost transmission shaft on the inclined surface 3 is moved to the feeding inclined plate 1001. At the same time, the transmission shaft contacts the baffle rod 1301, and the upper end surface of the feeding inclined plate 1001 is arranged at an angle. At this time, the transmission shaft can be stably placed through the cooperation between the upper end surface of the feeding inclined plate 1001 and the baffle rod 1301 to prevent the transmission shaft from sliding.

[0062] like Figure 8 As shown, in this embodiment, the pin shaft 1309 is arranged on the side of the blocking rod 1301 close to the vertical plate 12, and the side of the roller 1304 close to the vertical plate 12 is in contact with the right side surface of the vertical plate 12; the side of the roller 1304 away from the vertical plate 12 is located inside the mounting groove, and the outer surface of the roller 1304 away from the vertical plate 12 will not be higher than the outer surface of the blocking rod 1301.

[0063] With this design, when the drive shaft needs to be loaded, the leftmost drive shaft on the inclined surface 3 moves to the feeding inclined plate 1001. At this time, the drive shaft is stably placed on the feeding inclined plate 1001, and the first automatic telescopic push rod 11 is used to drive the feeding push plate 10 to move upward. At this time, the feeding push plate 10 drives the drive shaft to move upward. During the upward movement of the drive shaft, the existence of the blocking rod 1301 prevents the drive shaft from contacting the vertical plate 12, thereby avoiding friction between the drive shaft and the vertical plate 12 and improving the use effect.

[0064] When the blocking rod 1301 is moving upward, the roller 1304 is in rolling contact with the vertical plate 12 to prevent the blocking rod 1301 from causing wear to the vertical plate 12 .

[0065] like Figure 4 As shown, when the feeding push plate 10 moves to the uppermost position, the blocking rod 1301 swings and tilts toward the direction close to the conveying inclined plate 14. At this time, the roller 1304 is in contact with the upper end surface of the conveying inclined plate 14, and the roller 1304 is located inside the mounting groove. The roller 1304 will not affect the rolling of the transmission shaft. At this time, the transmission shaft will roll to the left along the blocking rod 1301 and the conveying inclined plate 14 to complete the transportation and loading operation of the transmission shaft.

[0066] like Figure 6 and Figure 7 As shown, in this embodiment, a mounting groove 1305 is provided at a position on the left side of the feed inclined plate 1001 corresponding to each blocking rod 1301 , and a mounting cavity is provided inside the feed inclined plate 1001 .

[0067] The elastic hinge assembly includes a rectangular rod 1306 fixedly installed in the installation cavity of the feeding inclined plate 1001 and located on both sides of the installation slot 1305. The rectangular rod 1306 is arranged parallel to the conveying direction of the inclined surface 3, and a movable sleeve 1307 is slidably provided on the outer surface of the rectangular rod 1306.

[0068] A spring 1308 is sleeved on the outer surface of the rectangular rod 1306 , and two ends of the spring 1308 are fixedly connected to the corresponding movable sleeve 1307 and the inner surface of the feeding inclined plate 1001 .

[0069] A rotating shaft 1302 is fixedly installed at the lower end of the baffle rod 1301, and the rotating shaft 1302 is arranged vertically with the baffle rod 1301. The two ends of the rotating shaft 1302 are rotatably connected with the corresponding movable sleeves 1307 respectively. Torsion springs 1303 are respectively sleeved on the rotating shaft 1302 near its two ends, and the two ends of the torsion spring 1303 are respectively fixedly connected with the corresponding baffle rod 1301 and the movable sleeve 1307.

[0070] With this design, the transmission shaft rolls on the inclined plane 3, and when the transmission shaft rolls onto the feeding inclined plate 1001, the transmission shaft will contact the baffle rod 1301. At this time, the impact force on the baffle rod 1301 drives the movable sleeve 1307 to move through the rotating shaft 1302, and the movable sleeve 1307 slides along the rectangular rod 1306 and compresses the spring 1308. The compression spring 1308 is used to buffer the impact force, thereby improving the use effect and achieving better protection for the transmission shaft.

[0071] like Figure 1 and Figure 5 As shown, in this embodiment, a control component is also provided on one side of the conveying bracket 1, and the control component includes a controller 17. The controller 17 is installed on the front side of the conveying bracket 1, and the input end of the controller 17 is electrically connected to the first sensor 15 and the second sensor 16.

[0072] The first sensor 15 is installed on the left side of the upper surface of the horizontal plate 702 , and the second sensor 16 is installed on the right side of the vertical plate 701 .

[0073] The control ends of the first automatic telescopic push rod 11, the motor 503, and the second automatic telescopic push rod 703 are electrically connected to the controller 17 respectively, and the controller 17 outputs control signals for controlling the corresponding first automatic telescopic push rod 11, the motor 503, and the second automatic telescopic push rod 703 to work.

[0074] In this embodiment, the first sensor 15 and the second sensor 16 are both position sensors that can detect the positions of the transmission shaft and the right side plate 502 .

[0075] It is designed in this way that when the first sensor 15 on the horizontal plate 702 detects the transmission shaft on the inclined surface 3, the motor 503 stops, and then the up and down moving component 7 works to place the transmission shaft on the inclined surface 3 of the conveying bracket 1, and then the motor 503 drives the screw rod 505 to rotate in the opposite direction. When the second sensor 16 on the vertical plate 701 detects the right side plate 502, the motor 503 stops.

[0076] In addition to this embodiment, a baffle may be fixedly installed on the outer side of the conveying bracket 1 , and the height of the baffle is higher than the upper surface of the inclined surface 3 by a certain distance, so as to block the transmission shaft on the inclined surface 3 .

[0077] The present invention also provides a method for using a transmission shaft transport and loading device. Based on the above transmission shaft transport and loading device, the method comprises the following steps:

[0078] Step 1. In the initial state, the movable plate 6 is docked on the right side of the conveying bracket 1, and the transmission shaft bracket 8 is docked above the inclined surface 3. When in use, the transmission shaft to be transported is placed on the rubber pad 802 of the groove 801, and the motor 503 is started to drive the screw rod 505 to rotate. During the rotation, the screw rod 505 drives the movable plate 6 to move to the left. When the first sensor 15 on the horizontal plate 702 detects the transmission shaft on the inclined surface 3, the motor 503 stops.

[0079] Step 2, the second automatic telescopic push rod 703 contracts to drive the transmission shaft bracket 8 and the transmission shaft to move downward until the transmission shaft is placed on the inclined surface 3 of the conveying bracket 1, and the transmission shaft rolls toward the lower end of the inclined surface 3 under the action of gravity, thereby shortening the rolling distance of the transmission shaft and avoiding high-speed diving. In addition, no collision occurs between the transmission shafts, so that the transmission shafts are arranged in a straight line on the inclined surface 3 in sequence; then the motor 503 drives the screw rod 505 to rotate in the opposite direction, and when the second sensor 16 on the vertical plate 701 detects the right side plate 502, the motor 503 stops and waits for the next transmission shaft to be conveyed.

[0080] Step three, when loading is required, the leftmost transmission shaft on the inclined surface 3 moves to the top of the feeding inclined plate 1001, and at the same time, the transmission shaft contacts the baffle rod 1301 to stably place the transmission shaft, and then the first automatic telescopic push rod 11 is started to extend, driving the feeding push plate 10, the blocking assembly 13 and the transmission shaft to move upward. When the feeding push plate 10, the blocking assembly 13 and the transmission shaft move to the upper side, the restoring force of the torsion spring 1303 can drive the rotating shaft 1302 and the baffle rod 1301 to rotate to the left and reset. At this time, the baffle rod 1301 swings and tilts toward the direction close to the conveying inclined plate 14, and the transmission shaft rolls to the left along the baffle rod 1301 and the conveying inclined plate 14 to complete the transportation and loading operation of the transmission shaft.

[0081] In step three, since the roller 1304 on the blocking assembly 13 rolls along the vertical plate 12, it is possible to avoid friction between the transmission shaft and the vertical plate 12 during the pushing process, which will not cause wear on the transmission shaft and improve production quality.

[0082] In the step three, when the feeding push plate 10 moves to the uppermost position, the baffle rod 1301 swings and tilts toward the direction close to the conveying inclined plate 14. At this time, the roller 1304 is in contact with the upper end surface of the conveying inclined plate 14, and the roller 1304 is located inside the mounting groove. The roller 1304 will not affect the rolling of the transmission shaft. At this time, the transmission shaft will roll to the left along the baffle rod 1301 and the conveying inclined plate 14 to complete the transportation and loading operation of the transmission shaft.

[0083] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
