Description

Technical Field

[0001] This invention relates to the field of automotive parts testing technology, specifically to a testing device for automotive parts processing. Background Technology

[0002] With the improvement of living standards, cars have become a necessity for people's lives. As a result, the automobile manufacturing industry has become increasingly popular, leading to a significant increase in demand for cars. Currently, cars have gradually become a necessity for families. The production of a car involves many steps, among which the factory inspection of parts is particularly important. At present, most automobile parts processing plants do not pay enough attention to windshield wiper blades, which may result in some windshield wipers having product quality problems when leaving the factory, such as abnormal noise when wiping and weak cleaning ability. For car owners, a substandard windshield wiper poses a great safety hazard in rainy weather.

[0003] A search revealed Chinese patent CN218566879U, which discloses a testing device for automotive parts processing. This device uses a motor within a waterproof chamber to drive a windshield wiper blade to rotate back and forth on a work surface via a series of transmission mechanisms, simulating the operation of a windshield wiper blade for testing. However, it still has the following problems:

[0004] 1. Because the working surface is placed vertically, while in actual use, the windshield of the front of the car is tilted according to fluid dynamics to reduce resistance, and the windshield of the car is a slightly curved surface design, the existing technology cannot simulate the real situation of the above two problems, which will affect the test results.

[0005] 2. It cannot simulate real-world weather scenarios. Windshield wipers are typically turned on in the rain or when the windshield is cleaned with windshield washer fluid, but current technology cannot simulate this scenario and cannot detect whether the wiper blades are in contact with the windshield.

[0006] 3. The gear is driven to rotate by the arc rack, which in turn drives the retainer to swing left and right. If the gear ratio is too large, the power arm will be relatively short. If the output power of the motor is too small, the wiper will be difficult to rotate. At the same time, it will increase the difficulty of controlling the swing cycle of the retainer through the motor. If the swing speed of the wiper is too fast, it will cause serious errors in the test results. Summary of the Invention

[0007] Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this invention provides a testing device for automotive parts processing, primarily to solve the problem that existing technologies cannot simulate real rainy weather conditions for testing.

A reciprocating motor is installed inside the waterproof chamber. A gear disk is fixedly installed on the output shaft of the reciprocating motor. A sealed bearing is embedded inside the waterproof chamber. A gear disk is rotatably connected inside the waterproof chamber through the sealed bearing. The gear disk and the gear disk mesh with each other, and the gear ratio of the gear disk and the gear disk is 1:3.

[0016] As a further embodiment of the present invention, the wiper fixing mechanism includes an L-shaped rod, one end of which is welded and fixed to a gear disk II through a sealed bearing, and a fixing seat is welded and fixed to the upper end of the L-shaped rod. A snap-fit ​​groove is formed on the inner side of the fixing seat, and a through-type snap-fit ​​groove is formed on the surface of the fixing seat. Receiving grooves are formed on both sides of the snap-fit ​​groove. A snap-fit ​​block is slidably connected in the receiving groove. The cross-section of the snap-fit ​​block is a right-angled trapezoid, and a guide rod is integrally formed on the outer side of the snap-fit ​​block. One end of the guide rod passes through the receiving groove and is integrally formed with a limiting piece. A tension spring is welded and fixed to the inner side of the limiting piece, and one end of the tension spring is welded and fixed to the outer wall of the fixing seat.

[0017] As a further embodiment of the present invention, the spraying mechanism includes a fixed frame integrally formed on the upper end of the bottom shell. The fixed frame has through holes, and five sets of through holes are provided. A connecting pipe is inserted into the through hole. One end of the five sets of connecting pipes converges to form a water inlet. The other end of the five sets of connecting pipes is welded and connected to a water outlet. The water outlet has an inclined water outlet integrally formed on it, and the surface of the water outlet has several sets of evenly distributed micropores.

[0018] As a further embodiment of the present invention, the cleaning mechanism includes an installation strip, one side of which is fixedly attached with Velcro, and the Velcro is equidistant from each other.

[0021] Beneficial effects

[0022] Compared with the prior art, the present invention provides a testing device for automotive parts processing, which has the following advantages:

[0023] 1. This invention uses a wiper fixing mechanism to secure the wiper. The wiper can be directly fixed through a through-type slot, and the adjacent locking blocks provide additional fixing, making the fixed wiper more secure and less likely to fall off during testing. Furthermore, the locking blocks have a guiding structure for easy assembly and disassembly.

[0024] 2. In this invention, the reciprocating motor in the first drive mechanism ultimately drives the wiper fixing mechanism to drive the wiper to swing on the windshield. The gear ratio of gear disk one and gear disk two is small, the output power requirement of the motor is low, and the difficulty of controlling the swing speed of the wiper fixing mechanism through the reciprocating motor is also small.

[0025] 3. This invention simulates the structure of a real windshield through a front windshield mechanism, and the front windshield mechanism is installed at an angle through connecting columns, which can simulate the application scenario in real situations, making the test structure closer to the actual situation.

[0026] 4. This invention uses a spraying mechanism to spray water onto the windshield mechanism to simulate a real rainy day environment for testing. The windshield mechanism is equipped with an illumination mechanism on its inner side. The LED lights of the illumination mechanism can illuminate the slightly curved windshield, making the areas not covered by the wipers more visible and making it easier to spot abnormal wipers.

[0027] 5. The present invention drives the cleaning mechanism to slide on the outer surface of the windshield mechanism through the second driving mechanism. The towel strip in the cleaning mechanism can be quickly replaced by Velcro and can be attached to the slightly curved windshield surface by the action of the second tension spring, thereby cleaning the water stains left by the previous test and facilitating the quick conduct of the next test.

[0040] Reference Figures 1-8 A testing device for processing automotive parts includes a base body 1 and a wiper fixing mechanism 2. An illumination mechanism 3 with an angle of 60° between the base body 1 and the upper end of the base body 1 is provided. A transmission mechanism 4 for driving the wiper fixing mechanism 2 to rotate is provided at the lower end of the illumination mechanism 3. A windshield mechanism 5 is provided on the outside of the illumination mechanism 3. A spray mechanism 6 simulating a rainy weather environment is provided at the upper end of the illumination mechanism 3. A cleaning mechanism 7 that can slide to clean the windshield mechanism 5 is provided on the outside of the windshield mechanism 5. A drive mechanism 8 for driving the cleaning mechanism 7 to move and clean along the surface of the windshield mechanism 5 is provided on the other side of the illumination mechanism 3.

[0041] In particular, in this invention, the lighting mechanism 3 includes a bottom shell 301, the lower end of the bottom shell 301 is welded and fixed to the base body 1, and the upper end of the base body 1 is welded and fixed with two sets of symmetrical and inclined connecting columns 101. The upper end of the connecting columns 101 is welded and fixed to the bottom shell 301. The lighting mechanism 3 is installed on the connecting columns 101 at a 60° angle, which can better simulate the installation of the windshield in real situations.

[0042] It should be noted that a groove 302 is provided at the upper end of the bottom shell 301. Several sets of LED lights 303 arranged in an equidistant array are installed in the groove 302. The LED lights 303 are arranged in parallel. The LED lights 303 can illuminate the windshield mechanism 5 in front, making the areas not covered by the wipers more obvious.

[0043] In particular, in this invention, the outer side of the bottom shell 301 is integrally formed with a connecting seat 304, and four sets of connecting seats 304 are provided. The connecting seat 304 is provided with threaded mounting holes 305. The windshield mechanism 5 includes a micro-curved windshield 501. The outer side of the micro-curved windshield 501 is bonded and fixed with a connecting seat 502. The connecting seat 502 is provided with a through hole 503. The lighting mechanism 3 and the windshield mechanism 5 are detachably installed by bolts engaging with the threaded mounting holes 305. The bolt installation of the micro-curved windshield 501 has the advantage of easy disassembly. If too many LED lights 303 are damaged, they can be quickly disassembled and replaced.

[0044] It should be noted that the transmission mechanism 4 includes a waterproof chamber 401 integrally formed on the bottom shell 301. A reciprocating motor 402 is installed inside the waterproof chamber 401. A gear disk 403 is fixedly installed on the output shaft of the reciprocating motor 402. A sealed bearing 404 is embedded inside the waterproof chamber 401. A gear disk 405 is rotatably connected inside the waterproof chamber 401 through the sealed bearing 404. The gear disk 403 and the gear disk 405 mesh with each other, and the gear ratio of the gear disk 403 and the gear disk 405 is 1:3. The gear ratio of the gear disk 403 and the gear disk 405 is small, which requires low output power from the motor and makes it easier to control the swing speed of the wiper fixing mechanism 2 through the reciprocating motor 402.

[0045] In particular, in this invention, the wiper fixing mechanism 2 includes an L-shaped rod 201. One end of the L-shaped rod 201 passes through a sealed bearing 404 and is welded and fixed to a gear disk 405. A fixing seat 202 is welded and fixed to the upper end of the L-shaped rod 201. A snap-fit ​​groove 203 is provided on the inner side of the fixing seat 202, and a through-type snap-fit ​​groove 204 is provided on the surface of the fixing seat 202. Receiving grooves 205 are provided on both sides of the snap-fit ​​groove 203. A snap-fit ​​block 206 is slidably connected in the receiving groove 205. The cross-section of the snap-fit ​​block 206 is a right-angled trapezoid, and a guide rod 20 is integrally formed on the outer side of the snap-fit ​​block 206. 7. One end of the guide rod 207 passes through the receiving groove 205 and is integrally formed with a limiting piece 208. A tension spring 209 is welded and fixed to the inner side of the limiting piece 208. One end of the tension spring 209 is welded and fixed to the outer wall of the fixing seat 202. The through slot 204 in the fixing seat 202 is manufactured in imitation of the vehicle wiper mounting seat on the market. If the wiper is not installed using the slot, it can be snapped in place by the locking block 206 in conjunction with the tension spring 209. The locking block 206 can also assist the wiper installed by the slot in fixing and improve the firmness after fixing.

[0046] It should be noted that the spraying mechanism 6 includes a fixed frame 601 integrally formed on the upper end of the bottom shell 301. The fixed frame 601 has through holes 602, of which five sets are provided. Connecting pipes 603 are inserted into the through holes 602, and the connecting pipes 603 cannot slide freely. Rubber rings inside the through holes 602 provide resistance to the water outlet 605, preventing the water outlet 605 from sliding during spraying. One end of each of the five sets of connecting pipes 603 converges to form a water inlet 604. The other end of the connector 603 is welded and connected to a water outlet 605. The water outlet 605 has an integrally formed inclined water outlet 606. The surface of the water outlet 606 has several sets of evenly distributed microholes 607. The water outlet 605 can slide and adjust its extension position through the connecting pipe 603 to change the water outlet position. This allows for testing of wipers of different lengths. The water outlet 605 can also be completely retracted into the upper part of the bottom shell 301 to make way for the removal and installation of the windshield mechanism 5.

[0047] In particular, in this invention, the cleaning mechanism 7 includes an installation strip 701, on one side of which a Velcro 702 is glued and fixed, and the Velcro 702s are equidistantly arranged. A towel strip 703 is detachably connected to the outside of the installation strip 701 via the Velcro 702. The towel strip 703 can be directly torn off and replaced via the Velcro 702.

[0048] It should be noted that the second drive mechanism 8 includes an installation box 801 integrally formed on the bottom shell 301. The installation box 801 has a water leakage groove 810. The top of the installation box 801 is fixedly installed with a drive motor 802. The lower end of the drive motor 802 is fixedly connected with a threaded rod 803. The outer side of the threaded rod 803 is threadedly connected with a threaded drive plate 804. The outer side of the threaded drive plate 804 is connected with an elastic component 80, and the elastic component 80 is fixedly connected with the installation strip 701. The other side of the installation strip 701 is fixedly connected with an elastic component 81. The rotation of the drive motor 802 can drive the cleaning mechanism 7 to slide along the windshield mechanism 5, thereby cleaning the water stains on the surface of the micro-curved windshield 501.

[0049] In particular, in this invention, elastic component one 80 and elastic component two 81 include a rod 805 and a sleeve 806. A tension spring two 807 is fixedly installed inside the sleeve 806. Two sets of tension spring two 807 are symmetrically arranged. The other end of the tension spring two 807 is welded and fixed to the rod 805. In elastic component two 81, a slider 808 is fixedly connected to one end of the sleeve 806. A roller 809 is rotatably connected to one side of the slider 808. The roller 809 abuts against a groove opened in the side wall of the bottom shell 301. The slider 808 is inserted into the groove. This allows the cleaning mechanism 7 to maintain horizontal vertical movement along the micro-curved windshield 501, and the tension spring two 807 can always adhere to the surface of the micro-curved windshield 501.

[0050] The present invention is used in the following steps:

[0051] S1: Control the drive motor 802 to move the cleaning mechanism 7 to the top of its stroke to make way for the installation of the windshield wipers;

[0052] S2: A sample of some wipers in a batch is investigated. The wipers are fixed by the through slot 204 in the wiper fixing mechanism 2, and the wipers are pressed and fixed from the side by the block 206 under the action of the tension spring 209.

[0053] S3, the water inlet 604 in the spray mechanism 6 is connected to an external water pipe, and the water outlet 605 is pulled outward so that the micro-holes 607 on the surface of the water outlet 606 are aligned with the coverage area of ​​the wiper and the spray is turned on.

[0054] S4: Start the reciprocating motor 402 to drive the wiper fixing mechanism 2 to swing back and forth, and at the same time turn on the LED light 303 to illuminate the slightly curved windshield 501 to observe whether there is any abnormality in the operation of the wiper.

[0055] S5: After the test is completed, stop the water spray and the operation of the reciprocating motor 402, remove the tested wipers, and start the drive motor 802 to drive the cleaning mechanism 7 to clean and dry the windshield surface.

[0056] S6: Replace the wiper blades with new ones for testing;

[0057] S7: If the towel strip 703 is too damp or damaged, you can pull the installation strip 701 outward, tear off the old towel strip 703 and replace it with a new one.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
