Description

Technical Field

[0001] The invention relates to an external mobile flexible tightening workstation and a use method thereof, belonging to the technical field of engine assembly. Background Art

[0002] In the process of engine assembly, in order to improve production efficiency and ensure assembly quality, bolts are usually tightened by equipment or single-axis handheld electric guns. These two methods have largely realized the automation of bolt tightening and improved the overall efficiency of the assembly line.

[0003] However, in the actual production process, equipment or handheld electric guns sometimes malfunction, making it impossible to continue tightening the bolts. In this case, the current main response strategy is to use an air gun with a torque-limiting wrench for manual tightening. Although this emergency method solves the problems caused by equipment failure to a certain extent, its emergency plan is relatively simple and heavily relies on the traditional manual tightening and re-inspection mode.

[0004] The traditional manual tightening method is not only inefficient, but also difficult to ensure the consistency and accuracy of tightening, which to some extent affects the overall assembly quality of the engine. In addition, with the increasing demand for automated production, this emergency tightening method that relies on manual labor can no longer meet the needs of modern production lines. Summary of the invention

[0007] The installation platform comprises a platform bottom plate and a profile bracket, and the middle portion of the profile bracket is fixedly connected to the horizontally arranged platform bottom plate.

[0008] Each corner of the profile bracket is fixed with a right-angle connecting plate.

[0009] A universal rotating wheel is fixedly mounted on the lower end of the profile bracket.

[0012] S1: Fix the equipment line body to the line body fixing connection plate;

[0013] S2: Extend the blocking cylinder and set the qualified number of counters;

[0014] S3: After the pallet is in place, it is blocked by the blocking cylinder and stops moving. Tightening work is performed manually using a tightening gun;

[0015] S4: The electric gun controller sends a qualified signal to the counter. When the qualified number reaches the set number, the counter transmits the signal to the signal display light, the signal display light lights up, and transmits the signal to the solenoid valve;

[0016] S5: After receiving the signal, the solenoid valve controls the blocking cylinder to retract and release the pallet;

It can quickly respond to equipment or handheld electric gun failures, reduce the process of manually tightening with an air gun and a torque-limiting wrench, and thus improve production efficiency and quality assurance. It reduces the difficulty of employee operation, improves the quality of engine assembly, improves the smoothness and efficiency of the production process, and meets the needs of modern production lines for automated assembly.
