Description

Technical Field

[0001] This invention belongs to the field of linear sliding unit assembly machinery, and specifically relates to an automatic assembly production line for linear sliding units. Background Technology

[0002] A linear sliding unit generally consists of three parts: an aluminum block, a retaining ring, and a bushing. A linear slider is another name for a linear sliding unit. During the production process, linear sliding units typically require the installation of components such as retaining rings. However, conventional linear sliding units are mostly assembled manually by workers. This involves placing the aluminum block and bushing on an assembly line, and then using tools to install the retaining ring and bushing into the aluminum block as the linear sliding unit moves. This conventional method of assembly not only easily leads to the loss of parts and waste of raw materials, but also frequently results in missing parts, affecting product quality. Furthermore, assembling conventional linear sliding units on a multi-worker assembly line increases labor intensity and production time, significantly reducing production efficiency and increasing production costs.

[0003] Therefore, a new solution is needed to address this type of problem. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated assembly line for linear sliding units. This addresses the drawbacks of manual assembly of conventional linear sliding units, which is prone to errors such as lost parts and wasted raw materials, as well as missing parts affecting product quality. Furthermore, the addition of conventional linear sliding units to multi-worker assembly lines increases labor intensity and production time, significantly reducing production efficiency and increasing production costs.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automatic assembly production line for a linear sliding unit, comprising a workbench and a frame, characterized in that a feeding conveyor mechanism, an assembly station, and a discharging conveyor mechanism are sequentially and closely arranged on the workbench, and the feeding conveyor mechanism, the assembly station, and the discharging conveyor mechanism are all at the same horizontal height; the assembly station includes a first compression spring assembly station, an aluminum block flipping station, a pressure shaft assembly station, and a second compression spring assembly station arranged at intervals; the workbench on one side of the assembly station is respectively equipped with a first compression spring assembly mechanism, an aluminum block flipping mechanism, a pressure shaft assembly mechanism, and a second compression spring assembly mechanism corresponding to the first compression spring assembly station, the aluminum block flipping station, the pressure shaft assembly station, and the second compression spring assembly station; the workbench on the other side of the assembly station is also... A component transfer mechanism is provided in the same direction as the assembly station. A vibratory feeder for bushing feeding is also provided on the side of the aluminum block flipping mechanism away from the assembly station. A feeding cylinder, colinear with the assembly station, is also provided on the side of the first compression spring assembly station away from the aluminum block flipping station. The feeding cylinder is used to push the aluminum block. The first compression spring assembly mechanism completes the installation of the retaining spring at one end of the aluminum block at the first compression spring assembly station. The aluminum block flipping mechanism is used to flip the aluminum block with the retaining spring installed at one end. The compression shaft assembly mechanism completes the installation of the bushing inside the aluminum block at the compression shaft assembly station. The second compression spring assembly mechanism completes the installation of the retaining spring at the other end of the aluminum block at the second compression spring assembly station. The component transfer mechanism is used to move the aluminum block, placing the unassembled aluminum block in the corresponding position at each assembly station and moving the assembled aluminum block to the unloading conveyor mechanism.

The flipping cylinder is connected to the movable chuck, and the movable chuck is connected to the clamping claw. The clamping claw extends into the assembly station. The assembly station is also provided with a clamping claw clearance hole corresponding to the position of the clamping claw. The movable chuck is driven to rotate by the flipping cylinder, and the movable chuck drives the clamping claw to rotate. Furthermore, the pressure shaft assembly mechanism includes a pressure shaft cylinder, a bushing feeding track, and a bushing positioning mechanism mounted on the frame. One end of the bushing feeding track is connected to the vibratory feeder, and the other end is connected to the bushing positioning mechanism.

The output end of the pressure cylinder is provided with a punch, the diameter of which is smaller than the diameter of the circular hole of the circular vise clamp structure, and the center line of the punch is coaxial with the center of the circular hole. The discharge port of the vibratory feeder is positioned higher than the bushing feeding track, which is inclined downwards on the frame.

[0009] Furthermore, both the feeding conveyor and the unloading conveyor include a conveyor belt assembly and a drive motor.

[0010] Furthermore, the unloading conveying mechanism, the assembly station, and the feeding cylinder are in the same direction, and the assembly station and the loading conveying mechanism are distributed vertically.
