Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of loading test devices, specifically to a loading device using rollers and baffles. Background Technology
[0002] For some products, in order to verify their performance under certain working conditions, it is necessary to conduct loading tests to verify the product's performance and identify quality or design defects. Generally, a loading device is used to directly apply load to the product; when this is not possible, loading is achieved through tooling or a load connected to the product.
[0003] For dynamic loading, sometimes three requirements need to be met:
[0004] ① The direction of the loading force is a specific direction and does not change with the movement trajectory of the loaded object; when the test product deforms during the loading test, or when the movement trajectory of the loaded object itself is a complex curve, the direction of the loading force remains unchanged.
[0005] ②The loading speed of the object is extremely fast.
[0006] ③ When the loaded object moves to the designated position, the loading force applied to the loaded object must be stopped immediately.
[0007] If the above requirements are met using existing technology, a certain following mechanism and algorithm are needed to ensure that the loading position and load spectrum are relatively accurate. This undoubtedly requires building an additional following system, which increases costs. Once the object being loaded is in high-speed motion, the loading may fail due to insufficient following system capabilities, and may even pose a danger to on-site operators. Utility Model Content
[0008] This application proposes a loading device using rollers and baffles, which has good following ability. When the load object changes its load movement trajectory or deforms, the loading power mechanism follows the change in the position of the load object by extending or retracting the piston rod, and the timing of loading and unloading is controllable.
[0009] Therefore, this application provides a loading device using rollers and baffles, including a device frame and a loading power mechanism disposed on the device frame. The device frame is also slidably provided with a loading mechanism that applies force to the moving loading object through a sliding mechanism. The loading mechanism is drivenly connected to the loading power mechanism.
[0010] The loading mechanism includes a loading baffle connected to the loading power mechanism, and a sliding member fixed on the loading object, wherein the sliding member is in contact with the loading baffle.
[0011] It also includes a pressure sensing mechanism disposed between the loading power mechanism and the loading mechanism, the pressure sensing mechanism being communicatively connected to a control system, the control system driving and controlling the loading power mechanism.
[0012] By adopting the above technical solution: the device frame is used to support the entire device and install the above-mentioned mechanisms. The loading power mechanism can push the loading mechanism under the control of the control system, and apply force to the loading object through the loading mechanism, thereby testing the moving loading object. By setting a sliding part, the loading object can still be tested while it is moving, which improves the applicability of the loading device. By setting a pressure sensing mechanism, the current applied force can be sensed in real time, which makes it easy to adjust the applied force of the loading power mechanism under the control of the control system.
[0013] Optionally, the loading power mechanism includes a loading cylinder fixed to the device frame, and a loading baffle is hinged to the end of the piston rod of the loading cylinder.
[0014] By adopting the above technical solution: the loading cylinder can be an electric cylinder or a hydraulic cylinder, which is controlled by the control system and can change the magnitude of the applied force. By pushing the loading baffle, the loading baffle pushes the sliding part, and the loading object can be subjected to force for testing.
[0015] Optionally, the loading baffle is provided with an auxiliary frame for improving its rigidity, and the sliding mechanism is disposed between the auxiliary frame and the device frame.
[0016] By adopting the above technical solution, the auxiliary frame can support the loading baffle, which improves the strength of the loading baffle. The sliding mechanism allows the auxiliary frame and the device frame to slide against each other, which facilitates the loading power mechanism to push the loading baffle to move back and forth.
[0017] Optionally, the sliding mechanism includes a linear guide rail mounted on the device frame and a slider mounted on the auxiliary frame and slidably disposed within the linear guide rail.
[0018] By adopting the above technical solution: the linear guide rail is groove-shaped, the slider is located inside the linear guide rail, and the loading baffle can move back and forth under the drive of the loading power mechanism, thereby changing the state and magnitude of the applied force to carry out the loading test.
[0019] Optionally, the linear guide rails include four, with two on each of the upper and lower sides of the device frame, and the four linear guide rails are arranged on the device frame at the four corners corresponding to the auxiliary frame. The sliding member includes a directional wheel fixed to the loading object.
[0020] By adopting the above technical solution: In this solution, the movement stability of the loading baffle can be improved by setting four linear guide rails and sliders. The directional wheel is installed on the loading object, and its roller contacts the loading baffle and can roll on the loading baffle. The loading baffle can apply force to the directional wheel, thereby indirectly applying force to the loading object to carry out the loading test.
[0021] Optionally, the linear guide rails include two, one on the top and one on the bottom of the device frame.
[0022] By adopting the above technical solution: This solution uses a universal ball to replace the aforementioned directional wheel. Since the universal ball occupies less space, the linear guide rails can be reduced to one set at the top and one set at the bottom.
[0023] Optionally, the piston rod is hinged to the loading baffle via a trunnion, and the pressure sensing mechanism includes a pressure sensor disposed between the piston rod and the trunnion, the pressure sensor being electrically connected to the control system.
[0024] By adopting the above technical solution: when the loaded object moves from top to bottom, the force can be controlled by the value fed back by the pressure sensor. When the loaded object moves and its position shifts, the piston rod can be extended or compressed to correct it, so that the loading baffle is in close contact with the directional wheel to implement loading.
[0025] Optionally, the pressure sensing mechanism includes a pressure sensor disposed between the loading baffle and the auxiliary frame, the pressure sensor being electrically connected to the control system.
[0026] By adopting the above technical solution, the pressure sensor can more accurately reflect the magnitude of the force applied by the loading power mechanism.
[0027] Optionally, the loading surface of the loading baffle is inclined from top to bottom toward one side of the auxiliary frame, and the sliding member includes a universal ball fixed to the loading object.
[0028] By adopting the above technical solution, the loading baffle uses a downward-sloping surface to contact the universal ball, which can prevent the loading baffle from swinging during high-speed movement.
[0029] Optionally, the spherical ball makes spherical rolling contact with the surface of the loading baffle.
[0030] The working principle and beneficial effects of this application are as follows:
[0031] 1. It has good following ability. After adopting this utility model, when the load object changes its load movement trajectory or deforms, the loading power mechanism will follow the change of loading position by extending or retracting the piston rod.
[0032] 2. The timing of loading and unloading is controllable. With this invention, when the loaded object moves beyond the loading baffle at an extremely high speed, even if the loading power mechanism does not unload quickly, the loading force will not be continuously applied to the loaded object because the rollers are no longer in contact with the loading baffle.
[0033] 3. After adopting this utility model, the loaded object will be subjected to the frictional force generated by the additional roller. Since the coefficient of rolling friction is extremely small, this additional force is basically acceptable. Attached Figure Description

[0041] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0042] Example 1
[0043] like Figures 1-2As shown, this embodiment provides a loading device using rollers and baffles, including a device frame 100, which can be a steel frame. A loading power mechanism 200 is fixedly mounted on the device frame 100. A loading mechanism 500 that applies force to a moving loading object 400 is also slidably mounted on the device frame 100 via a sliding mechanism 300. The loading mechanism 500 is drivenly connected to the loading power mechanism 200. The loading mechanism 500 includes a loading baffle 510 connected to the loading power mechanism 200, and a sliding member 520 fixed on the loading object 400. The sliding member 520 is in contact with the loading baffle 510. A pressure sensing mechanism 600 is also provided between the loading power mechanism 200 and the loading mechanism 500. The pressure sensing mechanism 600 is communicatively connected to a control system, and the control system drives and controls the loading power mechanism 200.
[0044] The basic principle and effect of this embodiment are as follows: The device frame 100 is used to support the entire device and install the above-mentioned mechanisms. The loading power mechanism 200 can push the loading mechanism 500 under the control of the control system. The loading mechanism 500 applies force to the loading object 400, thereby conducting a loading test on the moving loading object 400. By setting the sliding member 520, the test can still be conducted on the loading object 400 when it moves, which improves the applicability of the loading device. By setting the pressure sensing mechanism 600, the current applied force can be sensed in real time, which makes it easy to adjust the applied force of the loading power mechanism 200 under the control of the control system.
[0045] The loading power mechanism 200 in this embodiment includes a loading cylinder fixed on the device frame 100. The end of the piston rod 210 of the loading cylinder is hinged to a loading baffle 510. The loading cylinder can be an electric cylinder or a hydraulic cylinder, etc. It is controlled by the control system and can change the magnitude of the applied force. By pushing the loading baffle 510, the loading baffle 510 pushes the sliding member 520, and the loading object 400 can be subjected to force for testing.
[0046] To improve the strength of the loading baffle 510, an auxiliary frame 530 is provided on the loading baffle 510 in this embodiment. The sliding mechanism 300 is disposed between the auxiliary frame 530 and the device frame 100. The auxiliary frame 530 can support the loading baffle 510, thereby improving the strength of the loading baffle 510. The sliding mechanism 300 allows the auxiliary frame 530 and the device frame 100 to slide against each other, which facilitates the loading power mechanism 200 to push the loading baffle 510 to reciprocate.
[0047] The sliding mechanism 300 in this embodiment includes a linear guide rail 310 mounted on the device frame 100 and a slider 320 mounted on the auxiliary frame 530 and slidably disposed within the linear guide rail 310. The linear guide rail 310 is groove-shaped, and the slider 320 is located inside the linear guide rail 310. Driven by the loading power mechanism 200, the loading baffle 510 can reciprocate, thereby changing the state and magnitude of the applied force to conduct a loading test.
[0048] In this embodiment, four linear guide rails 310 are included, with two on each of the upper and lower sides of the device frame 100. The four linear guide rails 310 are positioned on the device frame 100 at the four corners corresponding to the auxiliary frame 530. The sliding member 520 includes a directional wheel fixed on the loading object 400. In this embodiment, the arrangement of the four linear guide rails 310 and the sliding member 320 can improve the movement stability of the loading baffle 510. The directional wheel is installed on the loading object 400, and its roller contacts the loading baffle 510, allowing it to roll on the loading baffle 510. The loading baffle 510 can apply force to the directional wheel, thereby indirectly applying force to the loading object 400 for loading tests.
[0049] In this embodiment, the piston rod 210 is hinged to the loading baffle 510 via the trunnion 220. The pressure sensing mechanism 600 includes a pressure sensor disposed between the piston rod 210 and the trunnion 220. The pressure sensor is electrically connected to the control system. When the loading object 400 moves from top to bottom, the force on it can be controlled by the value fed back by the pressure sensor. When the loading object 400 moves and its position shifts, the piston rod 210 can be extended or compressed to correct the position, thereby making the loading baffle 510 fit tightly against the directional wheel to apply the load.
[0050] Example 2
[0051] Reference Figure 3 and Figure 4 The differences between this embodiment and Embodiment 1 are as follows:
[0052] In this embodiment, there are two linear guide rails 310, one at the top and one at the bottom of the device frame 100. A universal ball is used instead of the directional wheel in the first embodiment. Since the universal ball occupies less space, the linear guide rails 310 can be reduced to one set at the top and one set at the bottom.
[0053] The pressure sensing mechanism 600 includes a pressure sensor disposed between the loading baffle 510 and the auxiliary frame 530. The pressure sensor is electrically connected to the control system and can more accurately reflect the magnitude of the force applied by the loading power mechanism 200.
[0054] In this embodiment, the loading surface of the loading baffle 510 is inclined from top to bottom toward the auxiliary frame 530. The sliding member 520 includes a universal ball fixed on the loading object 400. The loading baffle 510 uses a downward inclined surface to contact the universal ball, which can prevent the loading baffle 510 from swinging during high-speed movement.
[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
