Description

Technical Field

[0001] The utility model relates to the technical field of new material testing machines, in particular to a new material testing machine with a buffer protection function. Background Technique

[0002] During the production process of new materials, it is necessary to conduct crushing test detection on them. However, during the crushing test, the new materials will fly everywhere, which will pose a certain safety hazard to the surrounding staff. In order to improve the test safety, a protection device is generally added near the testing machine.

[0003] For example, a Chinese patent with the patent application number 202120293796.X, a gravel impact testing machine with an anti-spray function. This patent solves the problem that the current gravel impact testing machine cannot well balance protection and convenient placement and removal of test materials by setting a rotating groove, partition plates, springs, push blocks, connecting rods, buffer plates, push-pull arms, propulsion seats, driving screws, driving motors and side plates. Usually, the four partition plates are flush with the top of the frame, facilitating people to put the test materials into the falling object groove and place them in the center of the impact plate. Start each driving motor, so that the driving screw drives each propulsion seat to move towards the direction close to the falling object groove, and the partition plates are pushed up by the push-pull arms until the partition plates are perpendicular to the frame.

[0004] However, when the above patent is used, multiple driving motors are required for adjustment, which not only makes the operation cumbersome, but also consumes a large amount of electric energy, thus greatly increasing the production cost. Content of the Utility Model

[0012] Optionally, four groups of the buffering mechanisms are provided, and the four groups of buffering mechanisms are respectively arranged at the four corners of the protective plate.

[0032] By adopting the above technical solution, the device can effectively prevent flying broken materials from hurting the surrounding workers through the protection plate 4 and the buffer plate 5, thus greatly improving the safety of the device.

[0033] In the embodiment of the present application, as Figures 1-3 shown, the adjusting mechanism includes a motor 7 installed on one side of the bottom plate 1, the output end of the motor 7 extends into the inner cavity of the bottom plate 1 and is fixedly connected with a positive and negative lead screw 8. The positive and negative threaded parts of the positive and negative lead screw 8 are both movably connected with a first lead screw nut 9. The center of the positive and negative lead screw 8 is fixedly connected with a first bevel gear 10. The two sides of the first bevel gear 10 are respectively meshed and connected with a second bevel gear 11 and a third bevel gear 12. The opposite sides of the second bevel gear 11 and the third bevel gear 12 are respectively fixedly connected with a first lead screw 13 and a second lead screw 14. The outer surfaces of the first lead screw 13 and the second lead screw 14 are movably connected with a second lead screw nut 15. The tops of the first lead screw nut 9 and the second lead screw nut 15 extend above the bottom plate 1 through a sliding groove 16 and are fixedly connected with the protection plate 4.

[0034] By adopting the above technical solution, the device can adjust the positions of the protective plates 4 in four directions simultaneously through the adjusting mechanism, so that the device can quickly conduct comprehensive protection on the periphery of the test bench 6, thereby effectively avoiding damage to the bodies of surrounding staff after the new material breaks. In addition, only one motor 7 is required for adjustment of the device, thus greatly reducing power consumption and significantly reducing production costs.

[0035] In the embodiment of the present application, as Figure 1 and Figure 4 shown, the buffer mechanism includes a buffer seat 17 installed on one side of the protective plate 4. A buffer spring 18 is fixedly connected inside the buffer seat 17, and the other end of the buffer spring 18 is fixedly connected to a buffer rod 19. The other end of the buffer rod 19 extends outside the buffer seat 17 and is fixedly connected to the buffer plate 5.

[0036] By adopting the above technical solution, the device can effectively reduce the impact force on the protective plate 4 and the buffer plate 5 when the broken materials splash through the buffer mechanism, thereby greatly improving the protection effect of the device and effectively reducing the damage suffered by the protective plate 4 and the buffer plate 5 during protection, and further greatly increasing the service life of the protective plate 4 and the buffer plate 5.

[0037] In the embodiment of the present application, as Figure 1 shown, four groups of buffer mechanisms are provided, and the four groups of buffer mechanisms are respectively arranged at the four corners of the protective plate 4.

[0038] By adopting the above technical solution, by utilizing the synergistic effect of multiple groups of buffer mechanisms, the buffer effect of the device is better.

[0039] In the embodiment of the present application, as Figure 2 shown, the external threads of the first lead screw 13 and the second lead screw 14 are opposite.

[0040] By adopting the above technical solution, the two second lead screw nuts 15 on the outer surfaces of the first lead screw 13 and the second lead screw 14 can move towards each other or away from each other simultaneously.

[0041] In the embodiment of the present application, as Figure 1 shown, a buffer pad is fixedly connected to the outer surface of the buffer plate 5.

[0042] By adopting the above technical solution, the buffer effect of the device can be greatly improved by utilizing the buffering effect of the buffer pad.

[0043] In the embodiment of the present application, as Figure 2 shown, the inner diameter of the sliding groove 16 is adapted to the widths of the first lead screw nut 9 and the second lead screw nut 15.

[0044] By adopting the above technical solution, the rotation of the first lead screw nut 9 and the second lead screw nut 15 can be avoided.

[0045] In the embodiment of the present application, as Figure 1 shown, a controller 20 is fixedly connected to one side of the support frame 2.

[0046] By adopting the above technical solution, the controller 20 can be used to more conveniently control the electrical appliances inside the device.

[0047] During use, the operator first places the new material to be tested on the test bench 6, and then starts the motor 7 through the controller 20, so that the motor 7 drives the forward and reverse lead screw 8 to rotate. When the forward and reverse lead screw 8 rotates, it will drive the first lead screw nuts 9 at both ends of the forward and reverse threads to move towards each other under the limiting action of the chute 16, and at the same time drive the first bevel gear 10 to rotate. When the first lead screw nut 9 moves, it will drive the protective plates 4 on the left and right sides to move towards each other. When the first bevel gear 10 rotates, it will drive the second bevel gear 11 and the third bevel gear 12 to rotate by meshing. When the second bevel gear 11 and the third bevel gear 12 rotate, they will drive the first lead screw 13 and the second lead screw 14 to rotate respectively. When the first lead screw 13 and the second lead screw 14 rotate, they will drive the two second lead screw nuts 15 to move towards each other under the limiting action of the chute 16, so that the second lead screw nuts 15 can drive the protective plates 4 on the front and back sides to move towards each other, so that the device can quickly move the four protective plates 4 to the periphery of the test bench 6, so that the device can quickly perform a comprehensive protection treatment on the periphery of the test bench 6, and thus can effectively avoid damage to the bodies of the surrounding staff after the new material is broken. In addition, only one motor 7 needs to be used when the device is adjusted, so that the power consumption is greatly reduced, and thus the production cost is greatly reduced. After the protective plate 4 is in place, the operator then starts the test machine main body 3 through the controller 20 to perform a crushing treatment on the new material. At this time, a large amount of broken materials will fly out in all directions from the new material. When the broken materials impact the buffer plate 5, the buffer plate 5 will squeeze the buffer spring 18 through the buffer rod 19, so that the impact force of the broken materials on the buffer plate 5 can be effectively reduced by using the energy storage characteristics of the buffer spring 18, and thus the service life of the protective plate 4 and the buffer plate 5 is greatly improved.
