Description

Technical Field

[0001] The utility model relates to the technical field of impact wear resistance test of seals, and particularly relates to a test device for testing the impact wear resistance performance of flexible seals. Background Technique

[0002] During the actual use of flexible seals, they will be subjected to the "impact" mode, such as the valve body seal being continuously closed and squeezed, or the door seal being squeezed when the car door is closed. In order to test the influence of this "impact" mode on the surface coating of flexible seals, the existing wear-resistant instruments in the laboratory are all horizontal reciprocating wear testers, such as the imported Taber 5900 reciprocating wear tester from the United States or the domestic steel wire wear testing machine. However, these devices can only conduct horizontal wear tests on flexible seals and cannot achieve vertical wear resistance. Moreover, the horizontal wear test can only simulate the low-frequency wear of flexible seals on a horizontal plane or a single plane during use. For example, it cannot simulate the continuous slamming of the car door or the sudden extrusion during the use of the valve body seal. In addition, the test frequency of existing devices is generally low (not exceeding 2 Hz), far from reaching the high-frequency impact range (4 - 17 Hz) that may be encountered in actual applications, thus limiting the comprehensiveness and accuracy of test results. Therefore, how to develop a test device for vertically impacting flexible seals that can test the high-frequency repeated impact wear resistance performance of flexible seals in the vertical direction is an urgent problem to be solved currently.

[0030] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0031] As Figure 1-7As shown, a test device for testing the impact and wear resistance of a flexible seal 5 comprises: a shell 1 with an open front side, wherein the shell 1 comprises a base 101, two side baffles 102 and a rear baffle 103, the two side baffles 102 extend upward from the two side edges of the base 101 to a certain height, the rear baffle 103 extends upward from the rear side edge of the base 101 to a certain height, the base 101, the two side baffles 102 and the rear baffle 103 together form a test area, the front side of the shell 1 is open and can accommodate a vertical impact unit 2, a drive unit 3 and a bearing unit 4 in the internal space of the shell 1, and the internal space of the shell 1 is configured with: a vertical impact unit 2, a drive unit 3 and a bearing unit 4.

[0032] The vertical impact unit 2 includes a bottom plate 201 and two side plates 202. The two side plates 202 are vertically fixed at the bottom of the housing 1. The bottom plate 201 is arranged between the two side plates 202 and is horizontally extended and fixed. A wear plate 203 is slidably arranged between the two side plates 202. The bottom of the wear plate 203 is detachably provided with a paint plate 204 for vertically impacting the flexible seal 5, which is convenient for replacing the paint plate 204 of different materials to meet various test requirements. A certain distance is formed between the paint plate 204 and the bottom plate 201 to form a test space for placing the flexible seal 5. Among them, the two side plates 202 are arranged relatively and are roughly parallel to the side baffle 102. The bottom plate 201 is detachably arranged with the two side plates 202 respectively and the bottom plate 201 can adjust the height, thereby adjusting the distance between the paint plate 204 and the bottom plate 201, so as to simulate the working environment under different impact conditions.

[0033] The drive unit 3 includes a servo motor 301, which is fixed on the inner wall of the rear side of the housing 1. The output end of the servo motor 301 is connected to the eccentric shaft 302. The servo motor 301 is roughly perpendicular to the eccentric shaft 302. The bottom end of the eccentric shaft 302 is hinged with the wear plate 203 to drive the wear plate 203 to drive the paint plate 204 to reciprocate up and down. Among them, the axis of the eccentric shaft 302 does not coincide with the rotation center of the servo motor 301, that is, there is an eccentricity, so that when the eccentric shaft 302 rotates, its bottom end can produce radial displacement relative to the rotation center. Through the precise control of the servo motor 301, the strict setting of the impact frequency and stroke is ensured, which provides a guarantee for the reliability and repeatability of the test results. Among them, a support plate 104 is arranged on the inner wall of the rear side of the housing 1, and the servo motor 301 is fixed on the support plate 104.

[0034] The bearing unit 4, the bearing unit 4 includes a first bearing plate 401 vertically arranged on the bottom plate 201. The first bearing plate 401 is located at the middle position of the bottom plate 201. On both sides of the top of the first bearing plate 401, second bearing plates 402 are rotatably arranged respectively. The upper surfaces of the first bearing plate 401 and the second bearing plates 402 jointly form a bearing platform 403 for erecting the flexible seal 5. Among them, by rotating the second bearing plate 402, the position of the flexible seal 5 on the bearing platform 403 is adjusted, so that the point position or surface position where the paint board 204 vertically impacts the flexible seal 5. Among them, the bearing unit 4 adopts a modular design. Through the collaborative work of the first bearing plate 401 and the second bearing plates 402, a bearing platform 403 is jointly constructed, which can adapt to the test requirements of the flexible seal 5 in different installation postures (point contact or surface contact). The operator only needs to simply adjust the angle of the second bearing plate 402 to achieve precise transformation of the test position, broadening the application range and flexibility of the test device. Among them, the hinge between the first bearing plate 401 and the second bearing plates 402 is realized by a pin shaft, a bearing or other rotating elements for relative rotation.

[0035] As Figure 1 and Figure 7 shown, on both sides of the bottom plate 201, a plurality of first jacks (not shown in the figure) are arranged. Along the vertical direction of the side plate 202, a plurality of second jacks 202a are arranged at a certain interval. The first jacks and the second jacks 202a cooperate with each other and are fixed by screws 205. Among them, both the first jacks and the second jacks 202a are threaded holes. On the side plate 202, two rows of a plurality of vertically arranged second jacks 202a are arranged, and two first jacks are correspondingly arranged on the side part of the bottom plate 201. The operator can flexibly adjust the height of the bottom plate 201 according to actual needs. Pass the screw 205 through the corresponding second jack 202a and screw it into the first jack, then the precise adjustment and firm fixation of the position of the bottom plate 201 can be realized.

[0036] As Figure 1 and Figure 7 shown, two side plates 202 are arranged opposite to each other and are provided with T-shaped grooves 202b in the vertical direction. On both sides of the wear plate 203, connection blocks 203a are arranged. On the outer ends of the connection blocks 203a, T-shaped sliders 203b are arranged. The T-shaped sliders 203b are slidably sleeved in the T-shaped grooves 202b, so that the wear plate 203 can slide in the vertical direction, thereby driving the paint board 204 to impact the flexible seal 5. The connection blocks 203a and the T-shaped sliders 203b are connected by bolts, so that the connection between the connection blocks 203a and the side plate 202 is firm. Even in high-intensity impact tests, a stable connection state can be maintained, and loosening or falling off will not occur.

[0037] As Figure 1 and Figure 6As shown, a connecting seat 203c is disposed in the middle of the wear plate 203. A groove 203c1 is formed in the connecting seat 203c. A connecting rod 203c2 is disposed inside the groove 203c1. The connecting rod 203c2 is rotatably connected to the bottom end of the eccentric shaft rod 302. The rotational movement of the eccentric shaft rod 302 is converted into an indirect drive for the wear plate 203 through the connecting rod 203c2, so that the wear plate 203 can reciprocate along a predetermined trajectory.

[0038] As Figure 1-5 shown, movable struts 401a are hinged to both sides of the first bearing plate 401. A plurality of slots 402a are provided at certain intervals along the length direction of the bottom surface of the second bearing plate 402. The movable struts 401a are inserted into the slots 402a to adjust the angle between the second bearing plate 402 and the first bearing plate 401. One end of the movable strut 401a is connected to the first bearing plate 401 through a hinge structure. The other end of the movable strut 401a can be inserted into different slots 402a. When the movable strut 401a is inserted into the slots 402a at different positions, the angle of the second bearing plate 402 relative to the first bearing plate 401 changes accordingly, realizing the angle adjustment between the two. A strip-shaped storage groove is further disposed on the side of the first bearing plate 401. The movable strut 401a is embedded in the strip-shaped storage groove. When the second bearing plate 402 needs to be rotated downward to a position parallel to the first bearing plate 401, the movable strut 401a is stored in the strip-shaped storage groove, so that the second bearing plate 402 can be attached to the side of the first bearing plate 401. In addition, the movable strut 401a can be a telescopic rod to control the length of the movable strut 401a, and can more accurately adjust the angle between the first bearing plate 401 and the second bearing plate 402.

[0039] As Figure 2-4 shown, the included angle between the first bearing plate 401 and the second bearing plate 402 is 0° - 120°, so as to realize multiple test positions of parallel, inclined and vertical. As Figure 3 shown, the included angle between the first bearing plate 401 and the second bearing plate 402 is 0°. The first bearing plate 401 and the second bearing plate 402 are arranged in parallel, that is, the first bearing plate 401 and the second bearing plate 402 are attached together. The flexible seal 5 is arranged on the bearing platform 403 and is in an inverted U shape. The point position where the paint plate 204 vertically impacts the flexible seal 5 in this configuration can accurately simulate the impact force transmission and sealing performance at a specific angle. As Figure 2As shown, the included angle between the first bearing plate 401 and the second bearing plate 402 is 90°, the first bearing plate 401 and the second bearing plate 402 are vertically arranged, the flexible seal 5 is laid on the bearing platform 403 and forms an unfolded plane, so that the paint board 204 vertically impacts the surface position of the flexible seal 5. Among them, the flexible seal 5 is laid flat on the bearing platform 403 to form an unfolded plane, and this layout increases the contact area, enabling the vertical impact of the paint board 204 to be evenly distributed on the surface of the flexible seal 5. As Figure 4 shown, the included angle between the first bearing plate 401 and the second bearing plate 402 is 120°, the second bearing plate 402 is inclined upward relative to the first bearing plate 401, so that the paint board 204 vertically impacts two different point positions of the flexible seal 5. With such a setting, when the flexible seal 5 is vertically impacted by the paint board 204, it can bear the impact forces from two different points simultaneously, simulating the impact mode under complex working conditions, which helps to evaluate the durability and deformation ability of the flexible seal 5 in an inclined state.

[0040] In an embodiment not shown, heating tapes for adjusting the temperature of the flexible seal 5 are arranged on the upper surfaces of the first bearing plate 401 and the second bearing plate 402. By regulating the working temperature of the flexible seal 5, specific requirements under different test or application scenarios can be met.

[0041] In an embodiment not shown, a visual protection plate is detachably arranged on the front side of the housing 1. This protection plate can effectively isolate the influence of the external environment. The protection plate is made of a transparent material, so that during the test, the operator can clearly observe the real-time operation state of the internal key components or timely discover potential fault situations without opening the housing 1. In addition, this protection plate also protects the safety of the operator. During the test, the protection plate can effectively block potential hazards such as splashes and high temperatures, ensuring the personal safety of the operator.

[0042] In an embodiment not shown, an infrared detector is arranged on the rear side wall of the housing 1. The sensing end of the infrared detector faces the test space between the paint board 204 and the bottom plate 201. When the infrared detector senses any obstacle other than the test sample in the test space, the infrared detector transmits a signal to an external control system, and the control system automatically aborts the impact test, thereby ensuring the safety of the entire test process.

[0043] The test method of the present utility model is as follows:

[0044] Place the flexible seal 5 on the bearing platform 403 formed by the first bearing plate 401 and the second bearing plate 402. By adjusting the angle of the second bearing plate 402, the flexible seal 5 is placed in the required test position, ensuring that there is an appropriate initial distance between the paint plate 204 on the wear plate 203 and the flexible seal 5, and check that all component connections are secure.

[0045] By adjusting the rotational speed of the servo motor 301, set the impact frequency (4 - 17 Hz) of the paint plate 204 on the flexible seal 5. Calculate and adjust the up and down movement stroke of the paint plate 204 according to the eccentricity of the eccentric shaft rod 302 to ensure that the paint plate 204 can reach the specified compression height at the end of the impact.

[0046] Start the servo motor 301. The motor drives the eccentric shaft rod 302 to start rotating, and then drives the wear plate 203 and the paint plate 204 to move up and down vertically in a reciprocating motion. The paint plate 204 continuously contacts and impacts the flexible seal 5 at the set frequency and stroke, and at the same time generates a certain amount of compression on the flexible seal 5 at the end of the impact.

[0047] After a predetermined number of friction times, stop the test, check the wear of the coatings of the paint plate 204 and the flexible seal 5, observe whether there is rubber transfer on the paint plate 204, and record the relevant data.

[0048] Evaluate the impact wear resistance of the flexible seal 5 based on the observed wear and rubber transfer conditions.

[0049] Generally speaking, the test device for testing the impact wear resistance of flexible seals of the present utility model solves the problem that the existing wear-resistant equipment in the laboratory cannot complete the impact wear detection of the flexible seal coating. The device has a simple structure, is practical and convenient, and can adjust the impact wear frequency, displacement distance, compression height of the flexible seal sample, and different positions of impacting the flexible seal to achieve the anti-wear ability of the flexible seal coating under different compression amounts. The entire detection process is convenient to operate, fast and efficient. The driving unit of the present utility model can provide precise and controllable impact conditions. Through the design of the servo motor and the eccentric shaft rod, precise control of the impact frequency and stroke is achieved, ensuring the stability and repeatability of the test conditions. In addition, the height of the bottom plate is adjustable, and different height test requirements can be adapted without replacing complex components. By simply adjusting the distance between the paint plate and the flexible seal, a vertical impact wear test of the flexible seal at different heights can be realized. In view of the complex working conditions faced by flexible seals in actual applications, the present utility model can achieve multi-form testing of flexible seals through the configured bearing unit. By adjusting the angle of the second bearing plate, the working states of the flexible seal at different installation angles (such as point contact, surface contact, etc.) can be simulated, so as to comprehensively evaluate its impact wear resistance in various postures. The test device of the present utility model can simulate actual working conditions. The paint plate is used as the wear medium, and the use of the paint plate simulates the friction and impact conditions that the flexible seal may encounter in actual working conditions. By checking the wear conditions of the paint plate and the flexible seal coating and the rubber transfer on the paint plate, the durability and stability of the flexible seal under extreme conditions can be intuitively understood. At the same time, the device also has the ability of comprehensive evaluation, and can comprehensively consider multiple performance indicators, such as wear resistance, impact resistance, sealing effect, etc., providing a scientific basis for the comprehensive evaluation of the product.
