Description

Technical Field

[0001] This utility model relates to the field of differential pressure pipe manufacturing technology, specifically to a lifting and clamping platform for vehicle differential pressure pipe production lines. Background Technology

[0002] To control particulate matter emissions from engines, the primary method currently used is by installing particulate filters in the vehicle's emission system. A particulate filter is a type of filter that effectively reduces particulate matter emissions. It regenerates by first capturing particulate matter from exhaust gases and then oxidizing the captured particles.

[0003] To detect the pressure difference before and after a particulate filter, a differential pressure pipe is usually installed outside the exhaust pipe. The differential pressure pipe requires multiple processes during manufacturing, making the production line quite complex. Clamping fixtures are essential components in each manufacturing process. However, general clamping fixtures can only clamp the workpiece and cannot be moved after clamping, making them cumbersome to use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a lifting and clamping platform for vehicle differential pressure pipe production line. It uses three grippers on the top to clamp the workpiece and is equipped with two cylinders for double safety. During use, the clamping height can also be changed by lifting the top plate. It has a wide range of applications.

[0005] To address the aforementioned technical problems, this utility model provides a lifting and clamping platform for a vehicle differential pressure pipe production line, comprising a base plate and a top plate. Support arms are intersected between the base plate and the top plate. A central pivot is located between the support arms, and side pivots are located around the perimeter. A first fixed bearing and a first movable bearing are located on the base plate corresponding to the positions of the support arms. A second fixed bearing and a second movable bearing are located on the top plate corresponding to the positions of the support arms. A triangular pivot is located on the top plate. Sliding seats are provided at the three outer corners of the triangular pivot via connecting plates. A gripper is located on the top of each sliding seat, and a movable cylinder is located on both sides of one of the sliding seats.

[0006] Furthermore, the output end of one of the movable cylinders is connected to the sliding seat via an extension plate.

[0007] Furthermore, a slide rail is provided on the base plate corresponding to the position of the first movable shaft seat, a motor seat and a lifting drive motor are provided on both sides of the first movable shaft seat, a lead screw assembly is provided at the output end of the lifting drive motor, and a lead screw assembly shaft body connected to the side rotating shaft is sleeved on the lead screw assembly.

[0008] Furthermore, auxiliary holes are provided at intervals on the support arm, and reinforcing plates are provided between the auxiliary holes.

[0009] Furthermore, auxiliary support cylinders are provided around the top plate, and a support plate is provided at the output end of the auxiliary support cylinders.

[0010] Furthermore, both the first movable shaft seat and the second movable shaft include a synchronization plate.

[0011] The beneficial effects of this utility model are as follows: When using this device, the entire equipment is divided into two steps. The lifting operation is as follows: Start the lifting drive motor at the bottom, which drives the lead screw assembly to rotate. The rotation of the lead screw assembly drives the lead screw assembly shafts on both sides to move linearly, that is, it drives the side rotating shaft to move linearly (the direction of linear movement is limited by the first moving shaft seat and the slide rail). The two support arms will rotate along the central rotating shaft to realize the lifting of the top plate. The clamping operation is as follows: Start the moving cylinder on the top plate. The moving cylinder drives one of the sliding seats to move back and forth through the connecting plate. Thus, relying on the characteristics of the triangular rotating shaft, the three sliding seats move closer or further away at the same time to realize the clamping of the workpiece. The three grippers at the top realize the clamping of the workpiece. At the same time, two cylinders are set up for double safety. During use, the lifting of the top plate can also be used to change the clamping height, which has a wide range of applications. Attached Figure Description

[0021] Reference Figures 1 to 2 As shown, an embodiment of the lifting and clamping platform for a vehicle differential pressure pipe production line of this utility model includes a base plate 1 and a top plate 2. Support arms 3 are cross-arranged between the base plate 1 and the top plate 2. A central rotating shaft 4 is arranged at the center between the support arms 3, and side rotating shafts 5 are arranged around the perimeter. A first fixed shaft seat 6 and a first movable shaft seat 7 are arranged on the base plate 1 corresponding to the positions of the support arms 3. A second fixed shaft seat 8 and a second movable shaft seat 9 are arranged on the top plate 2 corresponding to the positions of the support arms 3. A triangular rotating shaft 10 is arranged on the top plate 2. Sliding seats 11 are arranged at the three outer corners of the triangular rotating shaft 10 through connecting plates. A gripper 12 is arranged on the top of the sliding seat 11. A movable cylinder 13 is arranged on both sides of one of the sliding seats 11.

[0022] A slide rail 15 is provided on the base plate 1 at the position corresponding to the first movable shaft seat 7. A motor seat 16 and a lifting drive motor 17 are provided on both sides of the first movable shaft seat 7. A lead screw assembly 18 is provided at the output end of the lifting drive motor 17. A lead screw assembly shaft 19 connected to the side rotating shaft 5 is sleeved on the lead screw assembly 18.

[0023] The entire equipment is used in two steps.

[0024] The lifting operation is as follows: Start the lifting drive motor 17 at the bottom, which drives the lead screw assembly 18 to rotate. The rotation of the lead screw assembly 18 drives the lead screw assembly shafts 19 on both sides to move linearly, that is, to move the side rotating shaft 5 linearly (the first moving shaft seat 7 and the slide rail 15 cooperate to limit the direction of linear movement). The two support arms 3 will rotate along the central rotating shaft 4 to realize the lifting of the top plate 2.

[0025] The clamping operation is as follows: Activate the moving cylinder 13 on the top plate 2. The moving cylinder 13 drives one of the sliding seats 11 to move back and forth through the connecting plate. Thus, relying on the characteristics of the triangular rotating shaft 10, the three sliding seats 11 move closer or further away at the same time to achieve workpiece clamping.

[0026] The output end of one of the movable cylinders 13 is connected to the sliding seat 11 via an extension plate 14, and the other movable cylinder 13 is directly connected to the sliding seat 11. When needed, only one movable cylinder 13 needs to be activated, and the other is kept as a spare.

[0027] Auxiliary holes 20 are provided at intervals on the support arm 3, and a reinforcing plate 21 is provided between the auxiliary holes 20. Since the support arms 3 are arranged in a cross manner and there are two in each direction, the reinforcing plate 21 is used to stabilize the structural strength between each pair.

[0028] Auxiliary support cylinders 22 are provided around the top plate 2. The output end of the auxiliary support cylinders 22 is provided with a support plate 23, which can temporarily place workpieces such as bottom molds.

[0029] Both the first moving shaft seat 7 and the second moving shaft include a synchronization plate 24 to ensure that the two support arms 3 operate synchronously and prevent the top plate 2 from tilting due to asynchrony.

[0030] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
