Description

Technical Field

[0001] The utility model relates to the technical field of automotive glove boxes, and particularly to a fatigue test tooling for an automotive glove box. Background Art

[0002] In the field of automotive production and manufacturing, before mass production in final assembly, fatigue tests need to be carried out on various parts of many automotive components to ensure the service life of the parts and meet the requirements of safe production.

[0003] For the automotive glove box assembly, the elastic locking pin is a semi - movable structure. In actual application, there will be tens of thousands of telescopic operations. In early manual inspection, generally, one out of every hundred pieces is inspected or the first inspection of each shift is carried out, etc.

[0004] The shortcoming of this inspection process is that in early manual inspection, high requirements are imposed on inspectors and the labor intensity is high. With the industrial revolution in recent years, with the popularization and application of a large number of automated and semi - automated equipment, more and more automotive production, inspection and assembly, etc. have transformed from the earliest labor - intensive form to digital and automated. Then, there will inevitably be a large number of corresponding demands for the fatigue inspection of such parts.

[0005] Due to the structural requirements of automotive components, semi - movable parts such as the elastic locking pin of the glove box must be subjected to regular and quantitative fatigue tests of components to meet the corresponding service life requirements when the components are actually installed in the vehicle. Moreover, the inspection reports of such movable components must retain inspection records for about 5 years for traceability.

[0006] However, due to the large amount of recordable repetitiveness required for inspection, in traditional manual inspection methods, either the buckle switch is repeatedly toggled manually, and while the elastic locking pin is telescoping, it is reset by the return spring. This inspection process has a large amount of repetitive work, and even the staff is prone to fatigue, thus resulting in low inspection work efficiency.

[0007] When multiple components need to be inspected, the workload is significantly increased, with high labor intensity and density. This is not suitable for modern highly efficient automotive production and assembly enterprises and affects the large - scale mass production of vehicle manufacturers. Content of the Utility Model

[0008] The purpose of the utility model is to provide a fatigue test tooling for an automotive glove box with high inspection efficiency and reduced labor intensity. Even for such a large amount of repetitive inspection operations, through automatic or semi - automatic tooling equipment, combined with an electronic measurement and automatic recording method, it can operate efficiently and stably, reducing labor intensity. At the same time, the supporting inspection, manufacturing and installation become simpler and more stable.

[0009] The purpose of the utility model is achieved as follows:

[0010] A fatigue test tooling for an automotive glove box, comprising a frame. A workbench is provided at the top of the frame. A positioning die, a pressing cylinder, a detecting telescopic cylinder and a counting sensor are provided on the workbench. A pressing block is provided on the cylinder rod of the pressing cylinder. The detecting telescopic cylinder and the counting sensor are oppositely arranged on both sides of the positioning die. The detecting telescopic cylinder is horizontally arranged on the workbench, and the horizontal height of the cylinder rod of the detecting telescopic cylinder is the same as that of the counting sensor. In the utility model, the detecting telescopic cylinder operates reciprocally at a high speed, repeatedly presses the elastic locking pin of the automotive glove box, and completes the fatigue test of automatically detecting the elastic locking pin. The utility model replaces manual operation, reduces labor intensity, improves production efficiency, thus realizes such a large number of repetitive detection operations, and saves material and labor costs.

[0011] The utility model can be further improved as follows.

[0012] A display screen is provided on the frame.

[0013] The counting sensor is an opposed photoelectric sensor.

[0014] A control box is provided on the frame.

[0015] The beneficial effects of the utility model are as follows:

The detecting telescopic cylinder of the utility model operates reciprocally at a high speed, repeatedly presses the elastic locking pin of the automotive glove box, and completes the fatigue test of automatically detecting the elastic locking pin. The utility model replaces manual operation, reduces labor intensity, improves production efficiency, thus realizes such a large number of repetitive detection operations, and saves material and labor costs.

[0017] 2. The high-speed counting sensor of the utility model automatically records, replaces manual recording, greatly reduces errors and omissions, and at the same time can export relevant data through USB, which is convenient for long-term preservation of measurement records.

[0018] 3. The utility model can be configured with different positioning dies according to different structures, with strong pertinence, stability and high efficiency.

[0027] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Embodiment 1, as Figures 1 to 7 shown, a fatigue test tooling for a glove box of an automobile includes a frame 1. A controller and a workbench 2 are provided at the top of the frame 1. A positioning die 3, a pressing cylinder 5, a detection telescopic cylinder 4, and a counting sensor 7 are provided on the workbench 2. A pressing block 6 is provided on the cylinder rod of the pressing cylinder 5. The detection telescopic cylinder 4 and the counting sensor 7 are oppositely arranged on both sides of the positioning die 3. The detection telescopic cylinder 4 is horizontally arranged on the workbench 2, and the horizontal height of the cylinder rod of the detection telescopic cylinder 4 is the same as the horizontal height of the counting sensor 7.

[0029] The glove box 8 of the present utility model is a prior art, and is provided with a latch switch, two elastic locking pins 81, a connecting rod, and a return spring. The two elastic locking pins 81 are telescopically arranged on both sides of the glove box 8 of the automobile. When a user toggles the latch switch, the latch switch drives the two elastic locking pins 81 to retract into the glove box 8 of the automobile through the connecting rod, and then the latch switch is released. The two elastic locking pins 81 are reset and extend out of both sides of the glove box 8 of the automobile under the action of the return spring.

[0030] As a more specific technical solution of the present utility model.

[0031] A display screen 9 is provided on the frame 1.

[0032] The counting sensor 7 is an opposed photoelectric sensor.

[0033] A control box 10 is provided on the frame 1.

[0034] The working principle of the present utility model is:

[0035] The worker places the car glove box 8 on the positioning membrane 3, and then starts the test tool of the utility model through the control box 10, and then the pressing cylinder 5 drives the pressing block 6 to descend and press the car glove box 8. The car glove box 8 is fixed on the positioning membrane 3, and the elastic locking pins 81 on both sides of the car glove box 8 are respectively aligned with the cylinder rod of the detection telescopic cylinder 4 and the counting sensor 7, and then the cylinder rod of the detection telescopic cylinder 4 is repeatedly horizontally extended and retracted, and the cylinder rod of the detection telescopic cylinder 4 repeatedly presses the elastic locking pin 81 on one side of the car glove box 8. The actions of the elastic locking pins 81 on both sides of the car glove box 8 are synchronous, and the elastic locking pins 81 on both sides of the car glove box 8 are synchronous. When the cylinder rod of the telescopic cylinder 4 is detected and the locking pin 81 is pushed into the car glove box 8, the elastic locking pin 81 on the other side of the car glove box 8 will also be retracted into the car glove box 8 simultaneously. At this time, due to the change in the distance between the elastic locking pin 81 and the counting sensor 7, the counting sensor 7 counts once, and then the cylinder rod of the telescopic cylinder 4 is detected to be contracted, and the two elastic locking pins 81 are retracted and extended by the reset spring. The elastic locking pins 81 on both sides of the car glove box 8 are continuously extended or retracted into the car glove box 8, and the counting sensor 7 continuously counts, thereby realizing the fatigue degree of the elastic locking pins 81 of the car glove box 8 being tested.
