Abstract
Description
Technical Field
[0001] This utility model relates to a chassis production line processing equipment, which is mainly used for chassis assembly line processing. Background Technology
[0002] During the manufacturing of vehicle frames, welding or precision machining is often required on both sides of the frame. In existing technology, after the frame reaches the corresponding welding station on the assembly line, it is usually necessary to manually or via overhead chains to remove the frame from the assembly line for welding or precision machining of smaller parts. When the frame needs to be flipped, it is done manually or via overhead chains again. After the frame is finished, it is then manually or via overhead chains to transport it back to the assembly line. This process is time-consuming, labor-intensive, inefficient, and disrupts the production cycle of the assembly line. Utility Model Content
[0003] In view of the above-mentioned defects in the existing technology, the present invention provides a chassis production line processing equipment that can easily load and unload chassis from the assembly line and easily flip chassis, which can improve production efficiency and increase production cycle time.
[0004] This utility model is achieved through the following technical solution: a chassis production line processing equipment, including an assembly line device, characterized in that: multiple spaced-apart tooling blocks for fixing the chassis are arranged on the assembly line table of the assembly line device; a movable flipping processing device is arranged on the side of the assembly line device; the front end of the flipping processing device is close to the assembly line device; a first hydraulic cylinder is arranged at the rear end of the flipping processing device to drive its movement; the flipping processing device includes a base, a lifting platform, a lifting mechanism, and a chassis rotation mechanism; rotatable ground wheels are respectively arranged at the four corners of the lower part of the base; the rear end of the base is connected to one end of the first hydraulic cylinder; the other end of the first hydraulic cylinder is connected to the hydraulic cylinder fixing seat; and the lifting platform is provided with... On the upper part of the base, the front part of the lifting platform is hinged to the upper end of the first support column at the front end of the base. The front end of the lifting platform is provided with at least two support feet perpendicular to its bearing surface. Two vertically arranged second support columns are fixed in the middle of the base below the lifting platform. The lifting mechanism includes two second hydraulic cylinders arranged on both sides of the base. One end of the second hydraulic cylinder is hinged to the base, and the other end of the second hydraulic cylinder is hinged to the bottom of the lifting platform. The frame rotation mechanism includes two third hydraulic cylinders. The two third hydraulic cylinders are respectively arranged on the outer sides of the base. One end of the third hydraulic cylinder is hinged to the base, and the other end of the third hydraulic cylinder is connected to a rotating shaft assembly that can be connected to a process hole on the frame.
[0005] In this invention, tooling blocks on the assembly line table of the production line equipment are used to fix the vehicle frame. The vehicle frame is vertically fixed on two or more tooling blocks, and the vehicle frame and tooling blocks can move together with the assembly line table. A first hydraulic cylinder is used to move the entire flipping processing device toward or away from the assembly line equipment. A lifting platform is used to support the vehicle frame, and the lifting platform can be flipped around the hinge axis on the first support column under the action of a second hydraulic cylinder. The flipping processing device can move the vehicle frame onto or off the assembly line equipment. Two third hydraulic cylinders are used to lift the vehicle frame on the lifting platform, and then manually rotate the vehicle frame 180 degrees. In operation, the chassis is vertically fixed to the assembly line table of the production line equipment by tooling blocks. After being transported to the processing position by the production line equipment, the flipping processing device is pushed towards the production line equipment by the action of the first hydraulic cylinder. At the same time, the lifting platform is lifted and flipped upward by the action of the two second hydraulic cylinders. As the flipping processing device gradually approaches the production line equipment, the support leg at the front end of the lifting platform extends to the underside of the chassis to support the chassis. When the cylinder rod of the second hydraulic cylinder retracts, it drives the lifting platform to fall back, and at the same time, it drives the chassis to be transferred to the lifting platform. The flipping processing device retreats to the processing position by the action of the first hydraulic cylinder. At this time, welding and other operations can be performed on the chassis on the lifting platform. When it is necessary to flip the chassis to process the other side, the rotating shaft assembly on the two third hydraulic cylinders can be manually connected to the corresponding process hole on the chassis. After the chassis is lifted by the two third hydraulic cylinders, it can be flipped and lowered back onto the lifting platform with manual assistance, so that welding and other operations can continue to be performed on the chassis. After the frame is processed, the first hydraulic cylinder drives the tilting processing device to move the frame on it to the assembly line equipment. The second hydraulic cylinder tilts the lifting platform and the frame on it together, and finally places the frame vertically on the tooling block on the assembly line table, so that it can enter the next production process.
[0006] Furthermore, the rotating shaft assembly includes a ball head, a rotating kingpin, and a locking pin. The ball head is connected to the end of the cylinder rod of the third cylinder. A transversely penetrating kingpin hole is provided in the center of the ball head. The rotating kingpin is movably inserted into the kingpin hole. The rotating kingpin has a radially penetrating rotating kingpin reset locking hole and a rotating kingpin fixing locking hole. The ball head also has a locking pin hole, in which the locking pin is inserted and engages with either the rotating kingpin reset locking hole or the rotating kingpin fixing locking hole on the rotating kingpin. The rotating kingpin is used to insert into a process hole on the frame for connection to the frame. After the rotating kingpin is inserted into the process hole on the frame, the locking pin is inserted into the rotating kingpin fixing locking hole to fix the rotating kingpin. When the rotating shaft assembly does not need to be connected to the frame, after pulling out the locking pin, move the rotating kingpin outward so that the rotating kingpin reset locking hole aligns with the locking pin hole on the ball head, and then insert the locking pin into the rotating kingpin reset locking hole to fix the rotating kingpin. When the frame needs to be lifted and tilted, connect the rotating kingpins of the rotating shaft assembly connected to the two third hydraulic cylinders to the corresponding process holes on both sides of the frame. The frame can then be lifted by the two third hydraulic cylinders, and then the frame can be tilted 180 degrees by manual assistance.
[0007] Furthermore, to ensure the reliable rotation of the lifting platform, an oblique support is provided between the first support column and the base.
[0008] Furthermore, a hydraulic station that supplies oil to each cylinder is located at the rear of the base.
[0009] The beneficial effects of this utility model are as follows: This utility model can automatically transport vehicle frame workpieces onto and off the production line via a flipping processing device, saving time and labor, and increasing efficiency. Furthermore, the flipping processing device enables the lifting and flipping of the workpieces, facilitating double-sided processing of the vehicle frame workpieces on the lifting platform. The workpiece flipping is simple and convenient. The lifting and flipping of the lifting platform in this utility model are both controlled by hydraulic cylinders, ensuring rapid and stable lifting and flipping. Moreover, the tilt angle of the lifting platform can be controlled through the hydraulic system, allowing the platform to remain at different angles for convenient workpiece processing.

[0019] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:
[0020] As shown in the attached figure, a vehicle frame production line processing equipment includes an assembly line device 5. The assembly line device 5 has a movable assembly line table 6. This assembly line device 5 is prior art and can be a chain conveyor, etc. Multiple spaced-apart tooling blocks 7 for fixing the vehicle frame are arranged on the assembly line table 6. Each tooling block 7 has a fixing groove, allowing the vehicle frame workpiece to be vertically fixed via the tooling blocks 7. A movable flipping processing device 3 is arranged on the side of the assembly line device 5. The front end of the flipping processing device 3 is close to the assembly line device 5, and the rear end of the flipping processing device 3 is equipped with a first hydraulic cylinder 2 to drive its movement. The flipping processing device 3 includes a base 3.1, a lifting platform 3.10, a lifting mechanism, and a frame rotation mechanism. The base 3.1 is a frame structure made of steel profiles. Rotatable wheels 3.2 are provided at the four corners of the lower part of the base 3.1. The rear end of the base 3.1 is connected to one end of the first hydraulic cylinder 2, and the other end of the first hydraulic cylinder 2 is connected to the hydraulic cylinder fixing seat 1. The lifting platform 3.10 is located on the upper part of the base 3.1. Two first support columns 3.7 are provided at the front end of the base 3.1. The lower parts of the front sides of the lifting platform 3.10 are respectively hinged to the upper ends of the two first support columns 3.7 via pins 3.8. The front end of the lifting platform 3.10 is also provided with at least two support feet 3.9 perpendicular to its bearing surface. Two vertically arranged second support columns 3.4 are fixed in the middle of the base 3.1 below the lifting platform 3.10, and the second support columns 3.4 are used to support the lifting platform 3.10. The lifting mechanism includes two second hydraulic cylinders 3.3, which are respectively disposed on both sides of the base 3.1. One end of each second hydraulic cylinder 3.3 is hinged to the rear of the base 3.1, and the other end is hinged to a cylinder rod support 3.13 at the bottom of the lifting platform 3.10 via a pin 3.12. When the cylinder rods of the two second hydraulic cylinders 3.3 extend, they can push the rear of the lifting platform 3.10 to rise and tilt forward around the hinge axis with the first support column 3.7. When the cylinder rods of the two second hydraulic cylinders 3.3 retract, they can drive the lifting platform 3.10 back to a horizontal position, or cause the lifting platform 3.10 to tilt and stop at different angles, facilitating processing operations by the operator. To ensure reliable tilting of the lifting platform, in this embodiment, an inclined support 3.6 is also provided on the rear side of each first support column 3.7, and the inclined support 3.6 is fixedly connected to both the first support column and the base 3.1. The frame rotation mechanism includes two third hydraulic cylinders 3.5, which are respectively disposed on the outer sides of the base 3.1. Each third hydraulic cylinder 3.5 is hinged at one end to the base 3.1, and the other end is connected to a rotating shaft assembly 3.11 that can be connected to a process hole on the frame. The two third hydraulic cylinders 3.5 should be arranged to avoid interference with the lifting platform and the frame.The frame rotation mechanism is used to rotate the frame workpiece on the lifting platform by 180 degrees. When the frame needs to be rotated, the rotating shaft assembly 3.11 is connected to the process holes on both sides of the frame on the lifting platform. After the two third hydraulic cylinders 3.5 lift the frame, the frame is rotated 180 degrees with manual assistance, and then the frame is lowered back onto the lifting platform for further processing. In this embodiment, the rotating shaft assembly 3.11 includes a rotating main pin 3.11.1, a ball head 3.11.2, and a locking pin 3.11.3. The ball head 3.11.2 is connected to the end of the cylinder rod of the third cylinder 3.5. The ball head 3.11.2 has a transversely penetrating main pin hole in its middle. The rotating main pin 3.11.1 is movably inserted into the main pin hole. The rotating main pin 3.11.1 has a rotating main pin reset locking hole 3.11.4 and a rotating main pin fixing locking hole 3.11.5 penetrating its radial direction. The ball head 3.11.2 also has a locking pin hole 3.11. 6. The locking pin 3.11.3 is inserted into the locking pin hole and can cooperate with the rotating master pin reset locking hole 3.11.4 or the rotating master pin fixing locking hole 3.11.5 on the rotating master pin to fix the rotating master pin 3.11.1. The rotating master pin fixing locking hole 3.11.5 is used to fix the rotating master pin 3.11.1 with the locking pin 3.11.3 when the rotating master pin 3.11.1 is inserted into the process hole on the frame. The rotating master pin reset locking hole 3.11.4 is used to fix the rotating master pin 3.11.1 with the locking pin 3.11.3 after the rotating master pin 3.11.1 is reset.
[0021] For ease of operation and relocation, a hydraulic station 8, which supplies oil to each cylinder, is located on the rear of the base 3.1. The hydraulic station 8 adopts existing technology and mainly includes an oil tank 8.1, an oil pump 8.2, a control valve group 8.3, and a control switch 8.4. The control valve group includes relief valves, directional valves, throttle valves, etc., used to control the pressure, flow rate, and direction of the hydraulic oil.
[0022] The working process of this utility model is as follows: The frame 4 is vertically fixed on the assembly line table of the assembly line equipment 5 by the tooling block 7, and after being transported to the processing position by the assembly line equipment 5, the flipping processing device 3 moves towards the assembly line equipment 5 under the action of the first hydraulic cylinder 2. At the same time, the lifting platform 3.10 flips forward under the action of the two second hydraulic cylinders 3.3. When the flipping processing device 3 gradually approaches the assembly line equipment 5, the support leg 3.9 at the front end of the lifting platform 3.10 extends to the underside of the frame 4 to support the frame. When the cylinder rod of the second hydraulic cylinder 3.3 retracts, it drives the lifting platform 3.10 to fall back, and at the same time, the frame 4 is transferred to the lifting platform 3.10. The flipping processing device 3 retreats to the processing position under the action of the first hydraulic cylinder 2. At this time, welding and other operations can be performed on the frame on the lifting platform 3.10. The lifting platform 3.10 can be kept in a horizontal position or at different angle positions by controlling the second hydraulic cylinder 3.3 according to the processing needs. When it is necessary to flip the frame 4 to facilitate the processing of the other side of the frame, the rotating master pins 3.11.1 in the two rotating shaft assemblies 3.11 can be manually inserted into the corresponding process holes on both sides of the frame 4. The locking pin 3.11.3 is then inserted into the locking pin hole 3.11 and the rotating master pin fixing locking hole 3.11.5 on the rotating master pin 3.11.1 to fix the rotating master pin 3.11.1. After the cylinder rods of the two third cylinders 3.5 extend and lift the frame 4, the frame 4 can be rotated manually. The entire frame 4 can rotate around the rotating master pins on both sides. After the frame has rotated, it is lowered onto the lifting platform 3.10 by the third cylinder 3.5. Then, the locking pins 3.11.3 and the rotating master pins 3.11.1 are pulled out, so that the frame 4 is separated from the rotating shaft assembly 3.11, and welding and other operations can continue to be carried out on the other side of the frame. After the rotating master pin 3.11.1 disengages from the frame, it can be reset and the locking pin can be inserted into the rotating master pin reset locking hole to fix it. After the frame is processed, the first hydraulic cylinder 2 and the flipping processing device 3 drive the frame 4 on it to move towards the assembly line equipment 5. After moving into place, the second hydraulic cylinder 3.3 flips the lifting platform 3.10 and the frame 4 on it forward together, and finally places the frame 4 vertically on the tooling block 7 on the assembly line table 6, and enters the next production process.
