Technical Field
[0001] This utility model relates to the field of semi-finished product transfer technology for brake pedal arm welded assembly, specifically to a damage-resistant semi-finished product transfer device for brake pedal arm welded assembly. Background Technology
[0002] The brake pedal arm welded assembly is a key safety component in the automotive braking system. Its manufacturing precision and quality directly affect the braking performance and safety of the entire vehicle. On the brake pedal arm processing production line, the welded semi-finished products need to be transferred between different processes, and the transfer operation in this process is crucial.
[0003] In the process of realizing this utility model, the inventors discovered that: Currently, the transfer of such welded semi-finished products is mostly accomplished using common material boxes, trolleys, or simple pallets. However, these conventional transfer methods have obvious drawbacks: First, during the transfer, especially when passing through bumpy sections, the parts are prone to shaking and bumping against each other, further increasing the risk of product damage. In addition, the fixed height of the containers makes it inconvenient for operators to store and retrieve parts, increasing labor intensity. Summary of the Invention
[0004] In order to solve the problems existing in the prior art, this utility model provides a damage-proof brake pedal arm welding assembly semi-finished product transfer device, which has the advantages of reducing the risk of product damage and allowing for container height adjustment.
[0005] Therefore, the technical solution of this utility model is as follows: a semi-finished product transfer device for a brake pedal arm welding assembly that prevents damage, including a transfer seat, a support frame on the top of the transfer seat, a lifting component fixedly connected to the outside of the support frame inside the transfer seat, a sliding plate between the left and right sides of the inner wall of the support frame, vertical rods on both the left and right sides of the bottom of the sliding plate, a connecting plate at the bottom of the left vertical rod with one end fixedly connected to the bottom of the right vertical rod, five irregularly shaped limiting seats symmetrically distributed on the left and right sides at the bottom of the sliding plate and the connecting plate, and a buffer component fixedly connected to the top of the sliding plate on the inner top wall of the support frame.
[0006] Preferably, the lifting assembly includes threaded rods. Two threaded rods are rotatably connected to the inner bottom wall of the transfer seat, extending to its top. These threaded rods are located on the left and right sides of the support frame, respectively. Threaded blocks are threaded to the exterior of each threaded rod. The left and right sides of the support frame are fixedly connected to the opposite sides of the two threaded blocks. First bevel gears located inside the transfer seat are fixedly connected to the exterior of each threaded rod. Two rectangular blocks, symmetrically distributed left and right, are fixedly connected to the inner bottom wall of the transfer seat. A dual-axis servo motor is fixedly connected to the inner bottom wall of the transfer seat, located between the two rectangular blocks. Rotating shafts penetrating the two rectangular blocks are fixedly connected to the two output shafts of the dual-axis servo motor. Second bevel gears meshing with the exterior of the two first bevel gears are fixedly connected to the opposite sides of the two rotating shafts.
[0007] Preferably, the buffer assembly includes a damper, the inner top wall of the support frame is fixedly connected to the damper which is fixedly connected to the top of the sliding plate, the inner top wall of the support frame is fixedly connected to two sleeves located on the left and right sides of the damper respectively, the inner walls of the two sleeves are slidably connected to a connecting post extending to its bottom and fixedly connected to the top of the sliding plate, and a compression spring is fixedly connected between the top of a single connecting post and the inner top wall of the sleeve.
[0008] Preferably, the bottom left and right sides of the transfer seat are fixedly connected with two movable wheels that are symmetrically distributed front and back, and each of the four movable wheels is equipped with a brake pad. The front side wall of the transfer seat is provided with a maintenance box door.
[0009] Preferably, each of the irregularly shaped limiting seats has limiting threaded holes on both the left and right sides of its bottom.
[0010] Preferably, the interior of the support frame is hollow and both its front and rear side walls are designed to be open.
[0011] Beneficial effects: Compared with existing technologies, this invention, through a buffer assembly installed between the top wall of the support frame and the sliding plate, effectively reduces the risk of component damage caused by bumps during transport. When the device vibrates over uneven surfaces, the sliding plate, its bottom-suspended irregularly shaped limiting seat, and the workpiece to be transported can undergo small vertical displacements. This kinetic energy is absorbed by the compression spring and dissipated through the damper, thus forming a highly efficient shock absorption system. This structure significantly buffers and isolates impacts and vibrations from the road surface, avoiding rigid collisions and bumps between workpieces and between workpieces and the device. It provides a flexible transport environment for precision welded semi-finished products, greatly improving the transport process. Safety is enhanced, and the device's practicality is improved. A lifting component inside the transfer seat enables electric adjustment of the carrier frame's height. By activating the dual-axis servo motor, power is transmitted via a rotating shaft and a second bevel gear to the first bevel gear, driving two threaded rods to rotate synchronously. This drives the threaded block and the carrier frame fixed to it to rise and fall smoothly. This design allows operators to flexibly adjust the carrier frame to the most comfortable storage and retrieval position based on their own height or the height of the next process interface, eliminating the need for bending over or tiptoeing, greatly reducing labor intensity, improving work efficiency and ergonomics, and further enhancing the device's practicality.

The inner bottom wall of the transfer seat 1 is fixedly connected with two rectangular blocks 34 that are symmetrically distributed on the left and right. The inner bottom wall of the transfer seat 1 is fixedly connected with a dual-axis servo motor 35 located between the two rectangular blocks 34. The two output shafts of the dual-axis servo motor 35 are fixedly connected with rotating shafts 36 that pass through the two rectangular blocks 34 respectively. The opposite sides of the two rotating shafts 36 are fixedly connected with second bevel gears 37 that mesh with the exterior of the two first bevel gears 33 respectively. A sliding plate 4 is slidably connected between the left and right sides of the inner wall of the support frame 2.

[0018] The working principle of this utility model: This anti-damage brake pedal arm welded assembly semi-finished product transfer device, through the buffer component 8 set between the inner top wall of the bearing frame 2 and the sliding plate 4, can effectively reduce the risk of component damage caused by bumps during the transfer. When the device vibrates when passing through uneven road surfaces, the sliding plate 4, the irregularly shaped limiting seat 7 suspended at its bottom, and the workpiece to be transferred can make a small displacement in the vertical direction. This kinetic energy is absorbed by the compression spring 84 and dissipated through the damper 81, thus forming a highly efficient shock absorption system. This structure significantly buffers and isolates the impact and vibration from the road surface, avoids rigid collisions and bumps between workpieces and between workpieces and the device, provides a flexible transportation environment for precision welded semi-finished products, greatly improves the safety of the transfer process, and enhances the practicality of the device. The lifting assembly 3, located inside the transfer seat 1, enables electric adjustment of the height of the support frame 2. By activating the dual-axis servo motor 35, power is transmitted via the rotating shaft 36 and the second bevel gear 37 to the first bevel gear 33, driving the two threaded rods 31 to rotate synchronously. This drives the threaded block 32, which is threadedly engaged with the rods, and the support frame 2, which is fixed on it, to rise and fall smoothly. This design allows operators to flexibly adjust the support frame to the most comfortable storage and retrieval position according to their own height or the height of the next process interface, without having to bend over or stand on tiptoe to operate. This greatly reduces labor intensity, improves work efficiency and ergonomics, and further enhances the practicality of the device. It also solves the problem that during transportation, especially when passing through bumpy sections, components are prone to shaking and colliding with each other, which further increases the risk of product damage. In addition, the fixed container height also makes it inconvenient for operators to store and retrieve components, increasing labor intensity.
