[0001] The present invention relates to the field of falling ball impact technology, and in particular to a falling ball impact detection device and a use method thereof. Background Art

[0002] The falling ball impact test is an experiment in which a ball of specified mass is dropped from different heights or balls of different masses are dropped from a specified height to measure the impact force generated by the falling ball.

[0011] Preferably, the method for using the falling ball impact detection device comprises the following steps: S1: The staff first controls the stepper motor to drive the rotating shaft to rotate on the rotating frame, so that under the cooperation of the linkage crank and the arc frame, the sliding frame moves downward on the sliding rod, thereby driving the sliding sleeve and the pressure rod to move downward synchronously through the basic frame, and synchronously driving the receiving plate to move downward in the lifting slot, and under the action of the transmission belt, the auxiliary turntable and the sleeve shaft are driven to rotate synchronously, so that one of the arc plates can be driven to pass through the oblique slot. At this time, the stepper motor stops working, and the arc plate is located in the oblique slot. At this time, the device is in the testing state. The staff will use the guide frame to make the ball to be tested enter and exit the lifting slot and impact in the direction of the receiving plate. , and perform impact detection. When the detection is completed, the stepper motor continues to work, thereby driving the arc plate to disengage from the oblique groove, and driving the transmission roller to enter one of the arc slide grooves, thereby driving the matching rotating column and the rotating sleeve shaft to rotate 180 degrees between the limiting frame and the matching frame, and in the process of rotation, the pressure rod and the receiving plate are driven to rotate synchronously through the positioning groove, and after the transmission roller is disengaged, the next arc plate enters the oblique groove, and under the action of the linkage crank, the receiving plate moves to the top of the lifting slot, and the ball on the receiving plate touches the side of the guide block provided with a limit spring plate, so that it rolls onto the guide slope under the reaction force, thereby completing the fixed-point collection; S2: When the ball falls toward the receiving plate, the receiving assembly drives one of the positioning blocks to drop to the top of the resistance block, and makes its bottom fit to the top of the resistance block. When the ball falls, the receiving plate causes the pressure rod to drop in the sliding sleeve through the telescopic spring under the action of the impact force, thereby driving the linkage toothed slot rod to drop in the triggering slot under the action of the positioning block and the resistance block, and driving the driving bevel gear to rotate during the descent, thereby driving the linkage bevel gear meshing with it to rotate, causing the counting gear meshing with the linkage bevel gear to rotate, so that the counting plate rotates synchronously, and is converted into data according to the gear ratio and displayed on the counting plate. After the impact force disappears, the receiving plate is reset under the action of the telescopic spring, and the driving bevel gear drives the linkage toothed slot rod to reset under the action of the coil spring. At this time, the stepping motor and The transmission roller drives the matching rotating column to rotate 180 degrees, and in the process of rotation, the triangular cone piece and the auxiliary triangular piece are used to drive the L-shaped trigger frame to move upward under the action of the spring telescopic rod. In the process of upward movement, the second synchronous gear and the first synchronous gear meshing therewith are driven to rotate synchronously through the matching toothed groove rod, thereby driving the two control gears to rotate in the same direction, and the reference frame is driven to move under the action of the linkage column, and then the several annular arc rails and the separation disk are driven to move upward under the cooperation of the wedge-shaped telescopic block, so that the moving base moves upward away from the bottom plate through the spring damping telescopic rod, so that the counting gear on the next separation disk is meshed with the side end of the linkage bevel gear, and when the L-shaped trigger frame is reset by the spring telescopic rod, the first synchronous gear will not rotate through the one-way bearing provided, thereby facilitating the analysis of the test data of the next sphere; S3: After all the spheres have been tested, the stepper motor can continuously work to drive the mobile base to continuously stretch the spring damping telescopic rod upward until, during the upward movement, the reset toothed rod engages with the second reset bevel gear, and drives the second reset bevel gear to rotate, causing the first reset bevel gear engaged therewith to rotate. At this time, the reset gear engages with the first reset bevel gear, thereby driving the reset gear to rotate one circle, and then driving the reset rod to rotate and move through the reset crank, so that the reset rod moves between several separation discs and the annular arc track, thereby driving each reset cone member to rotate, causing each counting gear to rotate, and causing several spring pressure rods to return to the opening, thereby resetting all counting discs.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the device is used, the staff first controls the receiving component to switch it to the test state, and then uses the guide component to make the ball to be tested fall onto the receiving component through the guide platform. At this time, the receiving component drives the display component to work through the linkage component according to the impact force of the ball, and converts the size of the impact force into data display in proportion. After the test is completed, the receiving component is controlled to restore it to the initial state, and the synchronous switching component is driven to work synchronously, so that it switches to the next display component and moves to the side end of the linkage component, so as to facilitate the testing of the next ball and record the data. After the test of the required ball is completed, the last display component is completed, and the staff controls the receiving component to work The synchronous switching component drives the reset component to work, thereby driving all display components to reset to the initial state, so as to facilitate the experiment on the next group of spheres, avoiding the need for staff to test one by one, and record the test data separately after the test is completed, simplifying the work steps, thereby improving the test efficiency. When each sphere is tested and moved to the top of the guide platform through the receiving component, the sphere can be rolled in a preset direction through the set guide component, so as to facilitate the unified collection of the spheres, improve the convenience of the device, thereby achieving the unified recording of data for multiple spheres while allowing the spheres that have completed the test to roll in the preset direction, so as to avoid the effect of low test efficiency and insufficient convenience.

[0013] In the present invention, the staff first controls the stepper motor to work, thereby driving the rotating shaft to rotate on the rotating frame, so that under the cooperation of the linkage crank and the arc frame, the sliding frame moves downward on the sliding rod, and synchronously drives the receiving plate to move downward in the lifting slot. At this time, the stepper motor stops working, and the device is in a testing state. The staff uses the guide frame to make the ball to be tested enter and exit the lifting slot and impact it in the direction of the receiving plate to perform impact detection. When the detection is completed, the stepper motor continues to work, thereby driving the matching rotating column and the rotating sleeve shaft to rotate 180 degrees between the limiting frame and the matching frame, and in the process of rotation, under the action of the linkage crank, the receiving plate moves to the top of the lifting slot, and makes the ball on the receiving plate touch the side of the guide block provided with a limit spring plate, so that it rolls onto the guide slope under the reaction force, thereby completing the fixed-point collection, thereby facilitating the unified collection of the balls and improving the convenience of the device.

[0014] In the present invention, when the sphere falls toward the receiving disk, the receiving disk causes the pressure rod to descend in the sliding sleeve through the telescopic spring under the action of the impact force, and drives the driving bevel gear to rotate during the descent, thereby driving the linked bevel gear meshing with it to rotate, so that the counting gear meshing with the linked bevel gear at this time rotates, so that the counting disk rotates synchronously, and the data is converted into data through the counting disk according to the gear ratio, and then the L-shaped trigger frame is driven to move upward under the action of the spring telescopic rod through the cooperation of the triangular cone part and the auxiliary triangular part, and the second synchronous gear and the first synchronous gear meshing with it are driven to rotate synchronously through the matching tooth groove rod, so that the movable base moves upward away from the bottom plate through the spring damping telescopic rod, so that the counting gear on the next separation disk meshes with the side end of the linked bevel gear, so as to facilitate the analysis of the test data of the next sphere, avoid the need for staff to test one by one, and record the test data separately after the test is completed, simplify the working steps, and thus improve the test efficiency.

[0015] In the present invention, after all the spheres have been tested, the stepping motor can continuously work to drive the movable base to continuously stretch the spring damping telescopic rod to move upward, until during the upward movement, the reset tooth groove rod is meshed with the second reset bevel gear, and drives the second reset bevel gear to rotate, so that the first reset bevel gear meshed therewith rotates, and at this time the reset gear and the first reset bevel gear are meshed with each other, thereby driving the reset gear to rotate one circle, and then driving the reset rod to rotate and move through the reset crank, so that the reset rod moves between several separation disks and the annular arc track, thereby driving each reset cone member to rotate, so that each counting gear rotates, and causing several spring pressure rods to return to the opening, thereby resetting all the counting disks, and thus facilitating the next work, thereby further improving the practicality of the device.
