Description

Technical Field

[0001] The invention relates to the field of detection technology, and in particular to a compression resistance detection device for a new material rubber gasket. Background Art

[0002] With the advancement of science and technology, new rubber gaskets are constantly emerging. These materials have better physical and chemical properties. However, before these new rubber gaskets are put on the market, they need to be tested for quality using compression performance testing equipment to ensure their reliability.

[0003] The current devices used to test the compressive performance of new material rubber gaskets often need to use a variety of test components to evaluate the overall and local compressive resistance of the gaskets when performing test tasks. However, the test components required for overall and local tests are not the same, and these components are usually fixed in specific positions of the test devices. The replacement process is cumbersome and complicated. Therefore, most testing institutions usually configure two test devices equipped with different components suitable for overall and local tests. This not only increases the number of hardware equipment, but also leads to additional time and manpower consumption when transferring rubber gaskets between the two devices. The whole process appears to be quite cumbersome and inefficient. Summary of the invention

[0004] The disclosed embodiment relates to a compressive performance testing device for a new material rubber gasket, which is improved so that the testing slide seat will enter a standby state after rising. In the standby state, the testing device will cancel the sliding restriction of the three switching slides inside the switching guide rail, so as to facilitate the switching of the testing mode of the testing device. At the same time, the testing device can also cancel the position restriction of the upper and lower testing dies in the standby state, so as to facilitate the staff to replace the worn mold structure. Such an arrangement can implement different methods of testing of new material rubber gaskets on one testing device, and the switching method is simple.

[0021] Please refer to Figures 1 to 8 : Embodiment 1: The present invention provides a compressive property detection device for a new material rubber gasket, including: a support base 1, on the top of which a loading column 2 is fixedly installed; a detection lower die 3 is sleeved and slidably installed on the loading column 2; an installation carrier plate 11 is fixedly installed between two support guide plates 9; a pushing block 12 is fixedly installed at the center of the bottom of the installation carrier plate 11; a chute is provided at the outer bottom of the support guide plate 9, and a detection sliding seat 13 is slidably installed inside the chute; a limiting base plate 15 is fixedly installed on the top of the detection sliding seat 13; a switching guide rail 16 is fixedly installed at the center of the top of the detection sliding seat 13; friction guide grooves 17 are provided at the front and rear ends inside the switching guide rail 16; a friction guide rail 18 is slidably installed inside the friction guide groove 17; a positioning insertion plate 20 is slidably installed on the outside of the limiting base plate 15; a connecting vertical plate 21 is fixedly installed at the outer end of the positioning insertion plate 20; a force-receiving block 23 is fixedly installed at the top end of the connecting vertical plate 21; a switching slider 25 is slidably installed on the friction guide rail 18; a retraction guide groove 26 is provided inside the switching slider 25; a limiting insertion piece 27 is slidably installed inside the retraction guide groove 26; a driven member 28 is fixedly installed at the top end of the limiting insertion piece 27; an installation guide groove 31 is provided at the bottom of the switching slider 25; an installation guide rail 33 is slidably installed inside the installation guide groove 31; a detection upper die 35 is fixedly installed at the bottom end of the installation guide rail 33; a connecting piece 36 is fixedly installed on the top of the three switching sliders 25. By setting three different detection upper dies 35, the new material rubber gasket can be subjected to three detections of overall compressive strength, local compressive strength and local puncture compressive strength respectively through this upper die, so that the detection aspects of this detection device are more complete.

[0022] Embodiment 2, on the basis of Embodiment 1, locking holes 4 are provided at the left and right ends of the lower die 3 for detection; support guide plates 9 are fixedly installed on the left and right sides of the top of the support base 1; a positioning clamping plate 5 is slidably installed at the connection part between the support base 1 and the support guide plate 9; the positioning clamping plate 5 is of an L-shaped structure; an inlay plate 6 is fixedly installed at the outer end of the positioning clamping plate 5; a spring A7 is jointly inlaid between the inner side of the inlay plate 6 and the outer side of the support guide plate 9; a locking column 8 is fixedly installed on the inner side of the positioning clamping plate 5; the position of the locking column 8 is horizontally corresponding to the position of the locking hole 4 from left to right; a detection push cylinder 10 is fixedly installed at the top of the outer side of the support guide plate 9; the left and right ends of the detection slide seat 13 are respectively fixedly connected to the output ends of the two detection push cylinders 10; transmission guide grooves 14 are provided at the left and right sides of the bottom of the detection slide seat 13; the outer end of the bottom of the transmission guide groove 14 is of an inclined structure; the inclined surface position of the transmission guide groove 14 is vertically corresponding to the highest end of the positioning clamping plate 5 from top to bottom; the switching guide rail 16 is located between the two limiting substrates 15; a spring B19 is jointly inlaid between the inner side of the friction guide rail 18 and the inside of the friction guide groove 17. The design of the friction guide rail 18 and the spring B19 can make the switching slider 25 have a certain frictional force in the switching guide rail 16. When no external force is applied by hand for sliding, the switching slider 25 will not slide. Through the improvement of the present invention, after the detection slide seat 13 rises, it will enter the standby inspection state. In the standby inspection state, the detection device will cancel the sliding restriction on the three switching sliders 25 inside the switching guide rail 16, which is convenient for switching the detection method of the present detection device. At the same time, in the standby inspection state, the present detection device can also cancel the position limitation on the detection upper die 35 and the detection lower die 3, which is convenient for the staff to replace the worn mold structure. Such a setting can perform different types of detections on the new material rubber gasket on one detection device, and the switching method is simple. Compared with performing different types of detections on multiple devices, the cumbersome gasket transfer steps are omitted.

[0023] Embodiment 3. On the basis of Embodiment 2, a spring C22 is jointly embedded between the inner bottom of the vertical plate 21 and the outer side of the limiting substrate 15; when the detection slide 13 is in the ascending state, the inclined surface of the force receiving block 23 will be pushed by the pushing block 12; a to-be-detected gasket 24 is placed inside the detection lower die 3, and the to-be-detected gasket 24 is a highly wear-resistant nano-composite rubber gasket; the left and right ends of the follower 28 are of an inclined structure; connecting plates 29 are fixedly installed on the left and right sides of the limit insertion piece 27; the connecting plates 29 are also slidably installed inside the contraction guide groove 26; a spring D30 is jointly embedded between the top of the connecting plate 29 and the inner top end of the contraction guide groove 26; a travel card 32 is fixedly installed at the left end inside the installation guide groove 31; a limit slot 34 is opened at the top of the installation guide rail 33; positioning slots 37 are opened on the left and right sides of the connecting piece 36; after the installation guide rail 33 completely slides into the installation guide groove 31, the position of the limit slot 34 will be vertically corresponding to the limit insertion piece 27 up and down; the bottom end of the detection upper die 35 in the middle is of a flat structure; a conical convex block is fixedly installed at the bottom end of the detection upper die 35 at the rear side; a cylindrical convex block is fixedly installed at the bottom end of the detection upper die 35 at the front side. When the detection slide 13 descends and is about to detect the new material rubber gasket, the positioning insertion plate 20 will automatically insert into the positioning slot 37 to limit the position of the switching slider 25, ensuring that the detection upper die 35 will not deviate in position during use. At the same time, the limit insertion piece 27 will also insert into the limit slot 34 to limit the detection upper die 35 inside the installation guide groove 31, ensuring that all the detection upper dies 35 can maintain a rigid connection with the switching slider 25 after descending, improving the stability of the detection upper die 35 during use.

[0024] Working principle of this embodiment: During use, first, the gasket 24 to be measured is manually placed inside the detection lower die 3, and then the detection push cylinder 10 is started to drive the detection slide 13 to move downward. After the movement, the pushing block 12 no longer pushes the inclined surface of the force-receiving block 23, so that the connecting vertical plate 21 drives the positioning plug 20 to move inward under the action of the spring C22, and it is inserted into the corresponding positioning slot 37 through the inward movement to limit the positions of the three switching sliders 25. When the positioning plug 20 moves inward, it will also push the inclined surface of the follower 28, causing it to move downward with the force, so that the limiting insert 27 is inserted into the inside of the limiting slot 34 through the downward movement to position the three detection upper dies 35, ensuring the stability of the detection upper die 35 during use. Moreover, at this time, the top end of the positioning clamp 5 will also slide into the inside of the transmission guide groove 14, and the inclined surface part of the transmission guide groove 14 is used to convert the downward force into an inward force, so that the locking column 8 is inserted into the locking hole 4 to fix the detection lower die 3. Thus, the fixing is completed. Until the detection upper die 35 enters the inside of the detection lower die 3 to perform a compressive test on the gasket 24 to be measured. After the test is completed, the detection slide 13 rises, and the above mechanism will be restored under the cooperation of the corresponding structures, enabling the switching slider 25 to resume sliding to facilitate switching the detection mode, and at the same time canceling the positioning of the detection upper die 35 and the detection lower die 3, facilitating the replacement of the worn mold structure.
