Description

Technical Field

[0001] The invention relates to a rapid steering advance and retreat system, belonging to the technical field of automobile manufacturing. Background Art

[0002] At present, automobile manufacturing presents a large-scale, automated production scale, and large-scale production has higher and higher requirements for the automation of the paint shop. The main function of the car body is to protect the driver and form a good aerodynamic environment. A good car body can bring better performance. In the process of processing and manufacturing the car body, the electrophoretic drying of the car body is a very important step. The electrophoretic drying of the car body is also a very important protection method, which can greatly extend the service life of the car body and ensure the long-term reliability of the car body. The coating conveying system is the key to the realization of automobile automated production, which affects the work quality and efficiency of the entire paint shop. In the production of the automobile paint shop, the car body topcoat is sent to the drying furnace for baking through the conveying device after painting, and then distributed to the post-processing workshop through the conveying device.

[0003] The existing baking equipment's automatic in-and-out walking chain needs to have a plug-in mechanism welded on the matching walking trolley when it is hung. This plug-in mechanism needs to be manually operated, and after baking is completed, the operation of pulling out the pin needs to be completed manually. Since the plug-in mechanism can only be placed at the bottom of the matching walking trolley, manual operation is extremely inconvenient, and it is very easy for the operator to be baked or scalded during the operation. Summary of the invention

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a rapid steering advance and retreat system.

[0005] The technical solution adopted by the present invention is: designing a rapid steering advance and retreat system, which includes a track and a conveyor vehicle, and the conveyor vehicle moves along the track; it also includes a block assembly, a traction member, a transmission mechanism, and a guide member, the block assembly is connected to the conveyor vehicle, two limit blocks are arranged on the block assembly, the traction member is located between the two limit blocks and is connected to the transmission mechanism, and the transmission mechanism is connected to the driving device for reciprocating motion; the traction member abuts against the limit block to drive the block assembly and thus drive the conveyor vehicle to move; the guide member is installed on a horizontal plane, and when the limit block moves to the guide member, it climbs along the guide member to release the traction member, thereby stopping the conveyor vehicle from moving.

[0006] Furthermore, the block assembly also includes an assembly shell; the limit blocks are respectively connected to both ends of the assembly shell.

[0007] Furthermore, the limit block includes a connecting shaft and a roller; the connecting shaft is located at both ends of the limit block, and the outer end of the connecting shaft is rotatably connected to the roller.

[0008] Furthermore, waist-shaped holes are respectively opened at both ends of the assembly shell, and the connecting shafts at both ends of the limit block are respectively placed in the waist-shaped holes. The positions of the connecting shafts corresponding to the waist-shaped holes are provided with card slots to limit the limit block to only move up and down in the waist-shaped holes but not rotate.

[0009] Furthermore, the assembly shell is a C-shaped shell with an opening facing downward.

[0010] Furthermore, the guide member includes a bracket and a boss; the bracket is connected to both ends of the boss, and the guide member is fixed by the bracket; when the roller of the limit block moves to the position of the guide member, it climbs along the boss.

[0011] Furthermore, the upper end of the boss is trapezoidal, and the boss is detachably connected to the bracket by opening a waist-shaped hole. The waist-shaped hole on the boss facilitates the adjustment of the installation height of the guide member to cooperate with the stopping of the conveying vehicle.

[0012] Furthermore, the traction member includes a right-angle plate and a sleeve, the sleeve is arranged at the corner of the right-angle plate, the traction member is rotatably connected to the transmission mechanism through the sleeve, and the block assembly is provided with a guide block for guiding the rotation of the traction member, and the guide block is installed in the middle of the block assembly; when the conveying vehicle moves forward, one side of the right-angle plate horizontally abuts against the transmission mechanism, and the other side abuts against a limit block at one end of the block assembly; when the conveying vehicle moves backward, the transmission mechanism switches the movement direction, the traction member moves to the guide block, the vertical side of the right-angle plate abuts against the guide block and then rotates downward, the original horizontal side of the right-angle plate becomes a vertical side and abuts against the limit block at the other end to drive the conveying vehicle to move in the opposite direction.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. A quick steering advance and retreat system provided by the present invention is mainly used in automobile body painting process, especially for automobile body entering and exiting a baking chamber, wherein the block assembly, traction member, transmission mechanism, and guide member cooperate with each other, and under the drive of the driving mechanism, the conveyor vehicle can automatically stop or automatically connect with the traction member to realize the automatic entry and exit of the conveyor vehicle in and out of the baking chamber; there is no need for manual unlocking, thus avoiding the hazards of heat radiation and burns to the operator; shortening the working time in and out of the baking chamber and improving production efficiency.

[0029] Example 1

[0030] like Figure 1 , Figure 5 As shown: a rapid steering advance and retreat system, comprising: a track 1, a transport vehicle 2, the track 1 is fixedly arranged parallel to the ground plane (not drawn in the ground plane diagram), and the wheels on both sides of the transport vehicle 2 are respectively placed in the track 1 and move along the track 1; the rapid steering advance and retreat system also includes a block assembly 3, a traction member 4, and a transmission mechanism 5; the transmission mechanism 5 adopts a transmission chain.

[0031] like Figure 1 , Figure 6As shown: the block assembly 3 is provided with a guide block 33, a limit block 32 and an assembly housing 31, and the limit block 32 and the guide block 33 each include a rectangular tube, a sealing plate, a connecting shaft and a roller; sealing plates are provided at both ends of the rectangular tube, the connecting shaft runs through the middle of the sealing plate and the rectangular tube, and rollers are rotatably provided at both ends of the connecting shaft. The assembly housing 31 is a C-shaped housing with an opening downward; the limit blocks 32 are respectively connected to both ends of the assembly housing 31 and can move up and down along the ends of the two ends of the assembly housing 31, and the guide block 33 is connected to the middle of the assembly housing 31 and can move up and down along the middle of the assembly housing 31; the specific method is to respectively open waist-shaped holes at both ends and the middle of the assembly housing 31, and the two ends of the connecting shaft of the limit block 32 and the guide block 33 are respectively placed in the waist-shaped holes, and the corresponding two ends of the connecting shaft of the limit block 32 and the guide block 33 are provided with a card slot to limit the limit block 32 and the guide block 33 to only move up and down along the waist-shaped hole. The stopper assembly 3 is connected to the transport vehicle 2 via a bracket folding plate 34 .

[0032] like Figure 1 , Figure 7 As shown: the traction member 4 includes a right angle plate 41 and a shaft sleeve 42, the shaft sleeve 42 is fixedly connected to the corner of the right angle plate 41, the shaft sleeve 42 is rotatably connected to the transmission mechanism 5, two arms extend from the connection between the transmission mechanism 5 and the traction member 4, and the shaft sleeve 42 of the traction member 4 is connected to the two arms of the transmission mechanism 5 through a shaft. The transmission mechanism 5 is connected to the driving device and reciprocates in a groove (not shown in the figure) below the ground plane. The right angle plate 41 does not exceed the limit blocks 32 at both ends of the block assembly 3.

[0033] like Figure 1 , Figure 8 As shown: the rapid steering advance and retreat system also includes a guide member 6, which is installed behind the block assembly 3, and includes a bracket 62 and a boss 61; the bracket 62 is connected to both ends of the boss 61, and the guide member 6 is fixed to the ground plane through the bracket 62; when the roller of the limit block 32 moves to the position of the guide member 6, it climbs along the boss 61, thereby driving the entire limit block 32 to move upward.

[0034] The working principle of the quick turn forward and backward system is:

[0035] like Figure 1 As shown: when the fast turning forward and backward system needs to move toward the baking chamber, one side of the right angle plate 41 is horizontally placed on the connecting pin of the transmission mechanism 5 and is held against by the connecting pin of the transmission mechanism 5 so as not to rotate downward, and the other side thereof is held against the inner side of the limit block 32 at one end of the stop block assembly 3, thereby driving the stop block assembly 3 to move and thus driving the conveying vehicle 2 to enter the baking chamber;

[0036] When the fast turning forward and backward system needs to exit the baking chamber, the transmission mechanism 5 switches the movement direction, and the right angle plate 41 moves with the transmission mechanism 5 to the position of the guide block 33, and the upper end of its vertical edge contacts the guide block 33 and rotates downward (such as Figure 2 As shown in FIG. 1 ), the original horizontal edge rotates upward to become a vertical edge against the inner side of the limit block 32 at the other end of the stopper assembly 3 (as shown in FIG. Figure 3 As shown), the stopper assembly 3 is driven to move in the reverse direction, and the quick turn forward and backward system exits the baking chamber.

[0037] The process of the fast turning forward and backward system exiting the baking chamber is as follows: Figure 4 As shown: when the stop block 32 moves to the guide member 6, its roller climbs along the boss 61 to drive the entire stop block 32 to move upward, the right angle edge of the right angle plate 41 is released, and the right angle plate 41 stops driving the stop block assembly 3 to move. The transmission mechanism 5 can also use a transmission belt.

[0038] Example 2

[0039] This embodiment is based on embodiment 1, and differs from embodiment 1 in that: a limit block 32 is set at one end of the block assembly 3, a clamping block or a limit block 32 is set at the other end of the block assembly 3, and the traction member 4 adopts a rectangular plate or a column and is fixedly connected to the transmission mechanism 5. The number of rectangular plates or columns can be set to only one or two structures such as limit blocks 32 corresponding to the two ends of the block assembly 3 are set to drive the transport vehicle 2 to move back and forth.

[0040] The system of the present invention improves the use efficiency of baking equipment, avoids the inconvenience of manual operation, avoids the occurrence of scalding and overheating during manual operation, changes the working environment of operators, and reduces the labor intensity of operators.

[0041] The specific implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
