Description

Technical Field

[0001] The present invention relates to the technical field of ski testing, and in particular to a device for accurately testing the elastic properties of a ski. Background Art

[0002] During the manufacturing process, skis undergo a series of tests, one of which is an elasticity test. Since skis are subjected to constant bending, flexing, deformation and other loads during movement, elasticity tests can simulate these conditions to ensure the safety of the skis in actual use. Therefore, elasticity tests are an important part of ensuring the quality of skis, which can ensure that the elastic performance of the skis meets the design requirements and avoid safety hazards caused by insufficient or excessive elasticity.

[0003] A ski board performance testing device with publication number CN117782481A in the prior art is equipped with a support frame, a rotating disk and an adsorption component. It can automatically load the test board transported by the first conveying mechanism into the test mechanism on the fixed table for testing, and can automatically move the tested test board to the surface of the second conveying mechanism for transportation. When the tested test board is deformed, the deformed test board can be moved to the surface of the placement table for subsequent research and analysis of the deformed test board.

[0004] Although the above-mentioned device can automatically load and test skis, there are still some defects in the actual testing process. Since the testing device lacks an automatic unloading component, after the ski test is completed, the tester needs to take out the skis and place them in a waste bin for subsequent centralized processing of the damaged skis.

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figure 1-8The device for testing the elastic performance of a precise ski board is shown, comprising a test bench 1, and support columns 2 are fixedly connected to the four corners of the bottom of the test bench 1, a display panel 3 is fixedly connected to the test bench 1, and an extrusion block 9 and the test bench 1 are provided with a data monitoring module, which can monitor the data of the ski board elasticity test in real time and provide real-time feedback on the display panel 3. This is a mature technology in the prior art and will not be described in detail here. A lower plate 4 is fixedly connected to the middle between the support columns 2, and a material collection box 5 for storing waste ski boards is provided on the lower plate 4. A T-slot 6 is provided at the top of the test bench 1, and a sliding frame 7 is provided on the inner side of the T-slot 6. Side frames 37 are slidably connected to both ends of the inner side of the sliding frame 7, and moving frames 8 are slidably connected to the inner sides of the side frames 37. A moving mechanism for simultaneously driving the side frames 37 to move toward the middle is provided on the sliding frame 7, and extrusion blocks 9 for squeezing the ski board are provided on the front sides of the side frames 37. A placement slot 10 is provided on the side close to the extrusion blocks 9, and side plates 11 are fixedly connected between the extrusion blocks 9 and the moving frame 8.

[0032] The inner side of the moving frame 8 is slidably connected with a moving block 12, and the side walls of the moving block 12 are fixedly connected with a round rod 13. An upper spring 14 is fixedly connected between the side wall of the moving block 12 and the inner side of the moving frame 8, and a lower spring 15 is fixedly connected between the side wall of the moving frame 8 and the inner side of the side frame 37. The rear side of the T-slot 6 is fixedly connected with a rear groove 16, and the round rod 13 is set at a position corresponding to the rear groove 16. Adjustment plates 17 are fixedly connected at both ends of the inner side of the rear groove 16. The side close to the top of the adjustment plate 17 is tilted, and an oblique groove 18 is provided on the side close to the adjustment plate 17. A pair of electric telescopic cylinders 19 are fixedly connected to the bottom of the lower plate 4. The output end of the electric telescopic cylinder 19 passes through the top of the lower plate 4 and is fixedly connected to the bottom end of the sliding frame 7. A pushing mechanism for pushing the material collecting box 5 at a fixed distance is provided in the T-slot 6;

[0033] The bottom end of the inclined groove 18 is set at a position corresponding to the round rod 13, and the bottom end of the adjusting plate 17 is fixedly connected to the top of the lower plate 4. The side away from the round rod 13 is set as a smooth arc surface, which can make the inclined surface of the top of the adjusting plate 17 more slippery and squeeze the round rod 13 to slide, thereby improving the silkiness during the operation of the device. A number of limit plates 20 for limiting the position of the ski board are fixedly connected to both ends of the inner side of the material collecting box 5 at equal distances. Through the setting of the limit plates 20, the waste skis inserted into the material collecting box 5 can be limited, thereby facilitating the extrusion block 9 to release the squeezing of the waste ski board and to withdraw it from the material collecting box 5, so as to avoid the waste ski board moving with the extrusion block 9 and affecting the collection effect of the device. A discharge trough 21 is provided on the rear side of the material collecting box 5 and on both sides of the limit plate 20. The setting of the discharge trough 21 avoids hindering the downward movement of the side plate 11, thereby hindering the normal unloading of the device;

[0034] The moving mechanism includes a drive motor 22, which is fixedly connected to the side wall of the sliding frame 7. A bidirectional screw rod 23 is rotatably connected to the inner side of the sliding frame 7. The bidirectional screw rod 23 is threadedly connected to the inner side wall of the side frame 37. The output end of the drive motor 22 passes through the inner side of the sliding frame 7 and is fixedly connected to the side wall of the bidirectional screw rod 23.

[0035] When conducting an elasticity test on a ski, first insert the ski to be tested into the placement slot 10 on the extrusion block 9, then control the drive motor 22 to start and drive the bidirectional screw rod 23 to rotate, thereby driving the two side frames 37 connected by threads to move toward the side close to each other, and then drive the extrusion block 9 to move toward the middle through the side plate 11, extruding the ski toward the middle, causing the ski to deform, and realizing the elasticity test of the ski. It should be noted here that the placement slot 10 can limit the two ends of the ski to prevent the two ends of the ski from warping upward during the test, affecting the elasticity test of the ski. As the ski is gradually squeezed, the ski reaches its elastic limit. When the ski is broken, the elastic force test of the ski is completed. At the same time, the driving motor 22 continues to drive the side frame 37 to move toward the middle, so that the extrusion block 9 moves quickly toward the middle (it should be noted that the moving speed of the moving mechanism during the ski test is different from the moving speed during the folding process. During the folding process, the extrusion block 9 needs to be driven quickly to move toward the middle), and the ski is folded along the broken part (it should be noted that although the board surface of the ski is broken, the glass fiber layer on the ski will not be broken, and the broken skis will be connected together). At the same time, the two ends of the ski will be able to be squeezed out of the groove 10, and the bottom of the ski will pass through the T-slot 6 and be above the material receiving box 5;

[0036] At the same time, the moving block 12 and the round rod 13 on the moving frame 8 move to above the rear groove 16, and then the electric telescopic cylinder 19 can be controlled to start pulling the sliding frame 7 downward, and at the same time drive the moving block 12 and the round rod 13 to move downward, and then the inclined surface at the top of the adjusting plate 17 will squeeze the round rod 13 to move, and then drive the moving block 12, the moving frame 8, the side plate 11 and the squeezing block 9 to move toward the middle, squeezing the skis tighter together and compressing the lower spring 15, and then, driven by the electric telescopic cylinder 19, the skis between the squeezing blocks 9 are inserted between the limit plates 20 in the material receiving box 5, and the side plates 11 are in the material discharging trough 21, and then when the skis are completely placed in the material receiving box 5, the round rod 13 will move to the side of the inclined slot 18, and then in the lower The round rod 13 is pushed into the inclined groove 18 by the thrust of the spring 15, and at the same time, the extrusion block 9 is driven to slide to both sides, releasing the extrusion on the ski board. At this time, the ski board is restricted by the limit plate 20 in the material receiving box 5 and will not open to both sides. Finally, the electric telescopic cylinder 19 can be controlled to start and drive the sliding frame 7 to move upward for reset. In this process, under the action of the inclined groove 18, the round rod 13 will be pulled to slide backward, and at the same time, the moving block 12 will be driven to slide on the inside of the moving frame 8, and the upper spring 14 will be gradually compressed. Then the round rod 13 slides out of the inclined groove 18, thereby releasing the extrusion on the round rod 13, and then the moving block 12 and the round rod 13 are pushed to reset under the elastic force of the upper spring 14. Then the drive motor 22 is controlled to flip and drive the extrusion block 9 to reset.

[0037] In order to improve the convenience of the device, a guide plate 24 for guiding waste chips into the material receiving box 5 is fixedly connected to the inner side of the T-slot 6 at an angle. Through the setting of the guide plate 24, it can be moved toward the middle through the extrusion blocks 9 on both sides, and the debris of the broken skis falling during the test above the test bench 1 can be pushed to the middle for cleaning, and then pushed into the T-slot 6 and introduced into the material receiving box 5 through the guide plate 24. The waste chips on the other side will fall directly into the material receiving box 5, which is convenient for subsequent centralized processing. The top of the lower plate 4 and on both sides of the material receiving box 5 are fixedly connected with a positioning plate 25. Through the setting of the positioning plate 25, the sliding position of the material receiving box 5 can be limited.

[0038] In order to be able to push the position where the skis were last placed in the material collection box 5 away before each unloading, the pushing mechanism includes a pushing plate 26, an L-shaped plate 27 is slidably connected to the front side of the inner wall of the T-slot 6, and a pair of hinged plates 28 are fixedly connected to the bottom of the L-shaped plate 27. The pushing plate 26 is rotatably connected between the hinged plates 28, and the side wall of the pushing plate 26 is obliquely fixedly connected to a limiting plate 29, and a cross plate 30 is fixedly connected to the front side of the material collection box 5, and a plurality of vertical plates 31 are fixedly connected to the top of the cross plate 30 at equal distances. It should be noted here that in order to ensure that the waste skis can be accurately inserted between the limiting plates 20, the spacing between each pair of limiting plates 20 is the same as the spacing between the vertical plates 31, and the bottom end of the pushing plate 26 extends to a position where it can be pushed to the vertical plates 31, and an L-shaped rod 32 is fixedly connected to the top of the L-shaped plate 27, and a pushing plate 33 for pushing the L-shaped rod 32 is fixedly connected to the front side of one of the extrusion blocks 9;

[0039] The top of the limiting plate 29 contacts the bottom of the L-shaped plate 27, and a return spring 34 is fixedly connected between the side wall of the limiting plate 29 and the bottom of the L-shaped plate 27. The setting of the return spring 34 facilitates the pushing plate 26 to move out from above the vertical plate 31. When the squeezing of the pushing plate 26 is released, the elastic force of the return spring 34 quickly pulls the limiting plate 29 and the pushing plate 26 to flip and reset. A return spring 35 is fixedly connected between the inner side of the T-slot 6 and the side wall of the L-shaped plate 27. The setting of the return spring 35 can drive the squeezing block 9 to reset by the moving mechanism. When the squeezing of the L-shaped rod 32 is released, the elastic force of the return spring 35 quickly pushes the L-shaped plate 27 to reset.

[0040] During the elasticity test of the ski board, it is necessary to first place the empty material receiving box 5 on the lower plate 4 and push the frontmost vertical plate 31 over the pushing plate 26 (there is no restriction on the other side of the pushing plate 26, so the pushing process will drive the pushing plate 26 and the limiting plate 29 to flip over, and reset after the vertical plate 31 is moved out), ensuring that the pushing plate 26 can push the vertical plate 31 to move, and then during the test, the extrusion block 9 is driven to move by the moving mechanism, and then the push plate 33 on the side wall of the extrusion block 9 pushes the L-shaped rod 32 to move, thereby driving the L-shaped plate 27 to slide on the inside of the T-slot 6 and gradually compressing the return spring 3 5. Since one side of the push plate 26 is restricted by the limiting plate 29 and cannot be turned over, when the L-shaped plate 27 slides and drives the push plate 26 to move, the push plate 26 pushes the vertical plate 31 to drive the horizontal plate 30 and the material receiving box 5 to move, thereby pushing away the position where the skis were last placed in the material receiving box 5, ensuring the normal unloading of subsequent skis. Subsequently, the position between the two squeezing blocks 9 gradually shrinks and the skis are squeezed together. The sliding frame 7 can be pulled by the electric telescopic cylinder 19 to drive the squeezing blocks 9 and the skis to move downward, and the skis can be inserted into the material receiving box 5. At the same time, the push plate 33 will keep squeezing the L-shaped rod 32;

[0041] Finally, during the reset process after the ski is put in, the squeezing block 9 and the pushing plate 33 are reset by the moving mechanism, thereby gradually releasing the squeezing of the L-shaped plate 27, and then pushing the L-shaped plate 27 to reset under the elastic force of the return spring 35. Then, when the pushing plate 26 is squeezed and reset, the pushing plate 26 will move to the other side vertical plate 31, and then, since there is no restriction on the other side of the pushing plate 26, it will be squeezed by the vertical plate 31 to make the pushing plate 26 flip over, and drive the limiting plate 29 to flip over, while stretching the reset spring 34. Then, when the L-shaped plate 27 is reset, the pushing plate 26 will move out of the vertical plate 31, thereby releasing the restriction on the pushing plate 26, and then pulling the limiting plate 29 and the pushing plate 26 to reset under the elastic force of the reset spring 34, and so on, realizing the function of pushing away the position where the skis were last placed in the material receiving box 5 before each unloading.

[0042] In order to improve the automation efficiency of the device, a touch sensor 36 is fixedly connected to the side wall of one of the side frames 37, and the touch sensor 36 is electrically connected to the moving mechanism and the electric telescopic cylinder 19 through the controller. Through the setting of the touch sensor 36, when the two side frames 37 are about to touch and the extrusion block 9 clamps the broken ski board, the other side frame 37 will touch the touch sensor 36, and then the touch sensor 36 transmits the signal to the controller, and the controller automatically controls the drive motor 22 to stop running and controls the electric telescopic cylinder 19 to start, so that the clamped ski board can be driven to slide down and inserted into the material receiving box 5, thereby realizing the automatic operation of the device.

[0044] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention.
