Description

Technical Field

[0001] The utility model relates to the technical field of rubber shock absorber detection, in particular to a testing machine for rubber shock absorbers. Background Technique

[0002] A rubber shock absorber, also known as a rubber shock isolator, has shapes such as cylindrical and rectangular. As an important type of shock-absorbing component, rubber shock isolators have been widely used in various machinery, automobiles, railway locomotives, water transportation vehicles, airplanes, and other aircraft. It can be said that wherever shock absorption and vibration isolation are required, rubber shock isolators are needed.

[0003] During the production process of cylindrical rubber shock absorbers, it is usually necessary to detect their tensile properties. However, the existing detection devices for rubber shock absorbers have single functionality and can only complete the tensile property detection of the same test sample. When other detections need to be completed, the test sample needs to be transferred to other equipment, which is cumbersome to operate, increases the detection cost of rubber, and reduces the detection efficiency. Content of the Utility Model

[0004] To achieve the above object, the utility model provides the following technical solution: A testing machine for rubber shock absorbers, including an operation table, on the top of the operation table, a conveying device, a detection component, a mounting plate, and a transfer component connected to the conveying device and the detection component are installed. A plurality of sample cylinders are fixed at the conveying belt end of the conveying device. A transplanting component and a marking component are installed on the mounting plate, and detectors are installed on both the marking component and the operation table;

[0005] The detection component includes a support table and a linear module installed on the operation table. On the top of the support table, a pneumatic chuck is installed, and at the bottom, a motor connected to the pneumatic chuck is installed. And at the top, a limit plate above the pneumatic chuck is fixed. The moving end of the linear module is provided with a clamping part above the limit plate.

[0006] Further, the transfer component includes a rotating cylinder installed on the operation table. The rotating end of the rotating cylinder is installed with a forward push cylinder. The ejecting end of the forward push cylinder is fixed with a forward push plate. On the forward push plate, an upward push cylinder is installed. The ejecting end of the upward push cylinder is fixed with an L-shaped plate. One end of the L-shaped plate is installed with a clamping part.

[0007] Further, the transplanting component includes a moving device installed on the mounting plate. The moving end of the moving device is installed with an upward push cylinder. The ejecting end of the upward push cylinder is fixed with a U-shaped plate. On the U-shaped plate, a forward top cylinder is installed. The ejecting end of the forward top cylinder is fixed with a top plate slidably connected to the U-shaped plate. A plurality of clamping parts are installed on the top plate.

[0008] Further, the jaw part is composed of two jaw cylinders fixed on the top plate and a rotating jaw located between the two jaw cylinders, and a pre-equilibration part is also provided on the mounting plate.

[0009] Further, the pre-equilibration part includes a pushing cylinder fixed on the mounting plate, and a clamping cylinder is installed at the ejecting end of the pushing cylinder.

[0010] Further, the marking assembly includes a belt drive device and a column fixed on the mounting plate. A suction cylinder opposite to one of the detectors is fixed at the rotating end of the belt drive device. A rotating device is installed on the column, a moving adjustment device is installed at the rotating end of the rotating device, and a marking pen is installed at the moving end of the moving adjustment device.

[0011] Further, a fine adjustment cylinder and a slide rail for the slider connected to the marking pen are installed at the moving end of the moving adjustment device, and the ejecting end of the fine adjustment cylinder is connected to the slider of the slide rail.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0013] For the testing machine of the rubber damping block, the transplanting assembly can transfer the sample to the marking assembly. The marking assembly cooperates with the detector to detect the outer surface of the sample, check whether there are cracks and mark the crack positions, and then transfer it away through the transplanting assembly. The qualified samples are successively sent to the pre-equilibration part and the testing assembly to complete the pressure, tension and torsion tests on the samples, and then cooperate with the transfer assembly and the conveying device to complete the blanking. Therefore, multiple tests can be completed on the same machine, thereby reducing costs and improving efficiency. Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 , a testing machine for rubber damping blocks in this embodiment includes an operating table 1. A conveyor device 2, a detection assembly 5, a mounting plate 9 are installed on the top of the operating table 1, and a transfer assembly 4 is connected to the conveyor device 2 and the detection assembly 5. A plurality of sample cylinders 3 are fixed at the conveyor belt end of the conveyor device 2. A transplanting assembly 6 is installed on the plate surface of the mounting plate 9, and a marking assembly 7 is installed on the left side of the transplanting assembly 6. Detectors 8 are installed on both the marking assembly 7 and the operating table 1. The detector 8 on the marking assembly 7 faces the transplanting assembly 6, and the detector 8 on the operating table 1 faces the detection assembly 5.

[0021] In the above structure, the prepared external sample rubber damping blocks are grabbed by the transplanting assembly and sequentially transferred to the marking assembly and the detection assembly. The detector completes the detection of surface damage. The detection assembly can realize the detection of pressing, stretching and torsion of the sample. The marking assembly marks the damaged position. After the detection is completed, the sample is placed in the sample cylinder through the transfer assembly, and the feeding operation is completed through the conveyor device.

[0022] Such as Figure 3For the shown direction, in order to achieve multiple detections, the detection component 5 includes a support platform 501 installed on the operation table 1. A linear module 505 is installed on the top of the operation table 1 and is located on the left side of the support platform 501. A pneumatic chuck 502 is installed on the top of the support platform 501, and a motor 504 that drives the pneumatic chuck 502 to rotate is installed at the bottom of the support platform 501. In addition, a limit disk 503 is fixed on the top of the support platform 501 and is above the pneumatic chuck 502. A limit hole for placing the sample is opened at the center of the limit disk 503. A clamping part 506 is installed on the moving end of the linear module 505 and is located above the limit disk 503 and opposite to the limit hole.

[0023] First, under the action of the limit hole on the limit disk, the sample can pass through and contact the pneumatic chuck at the bottom at the same time, so as to play a role in limiting the sample. Then the pneumatic chuck clamps and positions the bottom of the sample. Then, the linear module drives the clamping part to press down. At this time, the clamping end of the clamping part is closed, so the downward pressure detection of the sample can be completed.

[0024] When performing the second group of detections, the clamping end of the clamping part opens, clamps and fixes the top of the sample. At the same time, the bottom of the sample is clamped and fixed by the pneumatic chuck. Then, it cooperates with the linear module to stretch upward, so that the stretching detection of the sample can be completed.

[0025] When performing the third group of detections, the linear module drives the clamping part to move to an appropriate height and clamps and fixes the sample. At this time, the bottom is also clamped and fixed by the pneumatic chuck. Then, the motor drives the pneumatic chuck to rotate, so that the torsion detection of the sample can be completed.

[0026] As Figure 2 For the shown direction to achieve the blanking operation, the transfer component 4 includes a rotating cylinder 401 installed on the operation table 1. A front push cylinder 402 is installed at the rotating end of the rotating cylinder 401. A front push plate 403 is fixed at the ejecting end of the front push cylinder 402. The front push plate 403 is L-shaped and is also slidably connected to the front push cylinder 402. An L-shaped plate is fixed at the top of the front push plate 403. An upper top cylinder 405 is installed on the right side of the L-shaped plate. An L-shaped plate 406 is fixed at the ejecting end of the upper top cylinder 405. A clamping part 407 is installed at the left end of the top of the L-shaped plate 406. When the sample detection is completed, the rotating cylinder, the front push cylinder and the upper top cylinder can drive the L-shaped plate to rotate, move up and down and push forward. Therefore, the clamping part can be docked with the detection component and the conveying device. The sample is clamped by the clamping part to be removed from the detection component and placed into the sample cylinder and removed by the conveying device to complete the blanking operation.

[0027] As Figure 4In the shown direction, automatic feeding is realized. The transplanting assembly 6 includes a moving device 601 installed on the mounting plate 9. A pushing cylinder 602 is installed at the left mobile end of the moving device 601. A U-shaped plate 603 is fixed to the ejecting end of the pushing cylinder 602. A triangular plate is slidably connected to the right side of the pushing cylinder 602, and the top of the triangular plate is fixedly connected to the U-shaped plate 603. A front pushing cylinder 604 is installed at the top of the U-shaped plate 603 near the head end of the moving device 601. A top plate 605 slidably connected to the U-shaped plate 603 is fixed to the ejecting end of the front pushing cylinder 604. Three clamping parts are installed on the top plate 605. Through the moving device, the pushing cylinder and the front pushing cylinder, the top plate can be driven to move back and forth, left and right, and up and down. Therefore, the sample can be clamped and transferred by the three clamping parts, and the sample can be sequentially transferred to the marking assembly and the detection assembly to realize the operation of automatic feeding.

[0028] Among them, in order to realize the feeding and flipping of the sample, the clamping part includes two clamping cylinders 606 fixed to the bottom of the top plate 605, and a rotating clamp 607 installed at the bottom of the top plate 605 between the two clamping cylinders 606. A pre-equivalent part is installed at the top of the mounting plate 9 between the marking assembly 7 and the detection assembly 5. The transplanting assembly drives the clamping part to move. Therefore, the external sample can be transferred by the two clamping cylinders and the rotating clamp. First, the front clamping cylinder transfers the external sample to the marking assembly for placement. The rotating clamp can grab and transfer the sample to the pre-equivalent part, and can also drive the sample to rotate and adjust. Thus, the end where the sample is placed can also be detected, improving the uniformity of detection. At the same time, the back clamping cylinder transfers the sample to the detection assembly for detection, thus completing the transplanting and flipping of the sample.

[0029] In addition, the pre-equivalent part includes a pushing cylinder 10 fixed to the mounting plate 9, and a clamping cylinder 11 is installed at the ejecting end of the pushing cylinder 10. The pushing cylinder drives the clamping cylinder to move up and down to adjust the height, and the height is adjusted according to the height of the sample to set the appropriate distance for placement and clamping. Then, the clamping cylinder completes the clamping and fixing of the sample to achieve the function of predetermined waiting.

[0030] As Figure 4 In the shown direction, the marking assembly 7 includes a belt transmission device 701 and a column 703 fixed to the mounting plate 9. A suction cylinder 702 opposite to one of the detectors 8 is fixed to the rotating end of the belt transmission device 701. A rotating device 704 is installed on the column 703, and a moving adjustment device 705 is installed at the rotating end of the rotating device 704. A marking pen 706 is installed at the mobile end of the moving adjustment device 705. The suction cylinder holds, limits, and adsorbs and fixes the sample, and then drives the suction cylinder to rotate under the belt transmission device. Therefore, the surface skin damage of the sample is detected by the detector. When damage occurs, the rotating device and the moving adjustment device cooperate to adjust the marking pen to the damaged place for marking.

[0031] In addition, a fine adjustment cylinder 707 is installed on the moving end of the moving adjustment device 705, and a slider rail 708 connected to the marker pen 706. The ejecting end of the fine adjustment cylinder 707 is connected to the slider of the slider rail 708. Therefore, when the rotating device and the moving adjustment device drive the marker pen to move, the slider of the slider rail can be pushed by the fine adjustment cylinder, so that the marker pen can be driven to achieve fine adjustment.

[0032] The working principle of the above embodiment is as follows:

[0033] First, through the coordinated movement of the moving device, the upward pushing cylinder and the forward pushing cylinder, the first jaw cylinder is driven to place the sample into the suction cylinder for fixation. The belt transmission device drives the suction cylinder to rotate, and the detector completes the surface detection of the sample. When damage is detected, the rotating device drives the moving adjustment device to rotate to an appropriate angle, and then the moving adjustment device drives the marker pen to move closer to the damaged position for marking. At the same time, the fine adjustment cylinder can also be used to push the slider rail to drive the marker pen to adjust. When the distance does not need to be adjusted too much, fine adjustment can be performed through the fine adjustment cylinder. Then, the transplanting assembly drives the rotating jaw to be located at the suction cylinder. Under the action of the rotating jaw, the sample can be taken out and the orientation of the sample can be rotated and adjusted, so as to complete the surface detection of the whole sample, improve the quality. After the surface detection is completed, the rotating jaw cooperates with the transplanting to first place the sample into the clamping cylinder for pre-waiting, waiting for the second set of jaw cylinders to clamp the sample and place it into the limit hole of the limit plate. Then, the bottom sample is clamped and fixed by the pneumatic chuck, the clamping part is driven to press down by the linear module, and the top of the sample is clamped and stretched by the clamping part. At the same time, the pneumatic chuck is driven to rotate by the motor, so that the detection of pressing, stretching and twisting of the sample can be completed. After the detection is completed, the clamping of the sample is released, and the rotating cylinder drives the L-shaped plate to be located at the position of the detection component. Then, the forward pushing cylinder and the upward pushing cylinder drive the clamping part to approach the sample to complete the operation of taking out the sample. Then, it is transferred to the sample cylinder through the principle of the transfer assembly and sent away through the conveying device.

[0034] In summary, automatic multi-functional detection can be achieved, so that costs can be saved and the detection efficiency can be improved.
