Embodiment 1

[0036] The key advance and retreat cylinder 9 of the present invention is fixed on the test bench body 1 through the cylinder front end fixing seat 10 and the cylinder rear end fixing seat 11 .

[0037] The key advance and retreat cylinder 9 is fixed on the cylinder rear end fixed seat 11 by the cylinder clamp block 12 . Cylinder front end fixed seat 10, cylinder rear end fixed seat 11 and lock cylinder fixed seat 3 and key rotary cylinder 7 and key rotary cylinder 8 are all fixed by test bench backing plate 13. And the test bench backing plate 13 is horizontally fixed on the test bench body 1 . The test bench backing plate 13 is a steel piece, which can withstand greater force than the aluminum alloy test bench body 1 .

Embodiment 2

[0039] The electrical control part of the durability test bench of the present invention is controlled by a PLC controller 15 . The actuator of the entire test bench adopts PLC programming technology, which can flexibly compile different programs to meet the test requirements stipulated by different standards. Finally, the purpose of controlling the movement of the cylinder 7, the cylinder 8 and the cylinder 9 is achieved, so that it can test the durability of the automobile door lock cylinder.

Embodiment 3

[0041] The key forward and backward cylinder 9 , the key rotary cylinder 7 , and the key rotary cylinder 8 described in the present invention are respectively controlled by solenoid valves, and the solenoid valves are controlled by the PLC controller 15 .

[0042] The solenoid valve is controlled by the PLC controller 15, and the solenoid valve respectively controls the key rotation cylinder 7, the key rotation cylinder 8 and the key advance and retreat cylinder 9 to realize the insertion of the key and the rotation of the key with the lock cylinder, and finally achieve the purpose of locking the car door. Core 2 was tested for durability performance.

Abstract

The invention discloses an endurance test bed for a lock cylinder of a vehicle door. The mechanical part of the endurance test bed comprise a test bed body, a lock cylinder fixed seat, a lock cylinder key fixed block; the lock cylinder is fixed on the lock cylinder fixed seat by a lock cylinder fixture block, a key in-out cylinder is provided, and the lock cylinder key is fixed on a piston rod of the key in-out cylinder, the two sides of the lock cylinder key fixed block are respectively provided with a key rotating connecting block which protrudes outwards, and two key rotating cylinders are provided to push the two key rotating connecting blocks respectively so as to drive the lock cylinder key to make rotary motion in two directions. The technical proposal helps realize the endurance performance test of the lock cylinder of the vehicle door by high-precision pneumatic components in conjunction with programmable control of a PLC controller. The test bed has simple operation, time saving property, low labor intensity, good versatility and high economic benefit; and the test conditions can be set as required, and the obtained test data are accurate and truly reflect the endurance performance of the lock cylinder in service use.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing process equipment, and relates to manufacturing and testing equipment for vehicle body structures. Specifically, the invention relates to a car door lock cylinder durability test bench. Background technique [0002] There are many kinds of lock cylinders on automobile doors. Obviously, the safety of the door lock cylinder is the primary issue, and the durability of the mechanism of the door lock cylinder itself determines its service life and directly affects its safety. Various mechanisms, mainly the durability performance of lock cylinder plugging and rotating mechanisms are tested. At present, there is no report on the durability performance test of the door lock cylinder, and the domestic special test equipment for this aspect is still blank. Contents of the invention [0003] The first problem to be solved by the present invention is to provide a car door lock cylinder dur...
