Description

Technical Field

[0001] The invention relates to the technical field of steel ball detection, in particular to a wear-resistant steel ball drop testing machine. Background Art

[0002] The steel ball drop tester is a device used to test the impact resistance of materials. Its working principle is to let a steel ball of a certain weight fall freely from a specified height to impact the specimen in order to evaluate the impact resistance of the specimen. The steel ball drop tester adopts DC electromagnetic control. The steel ball is placed under the electromagnetic suction cup, and the steel ball is automatically sucked up. When the drop button is pressed, the suction cup instantly releases the steel ball, and the steel ball will fall freely to impact the surface of the specimen.

[0003] Chinese patent CN103323208B discloses a steel ball falling and collision test device, including a spiral hoist and a falling straight pipe. The spiral hoist is inclined and its top is connected to the top of the falling straight pipe. A collision straight pipe is installed on the outside of the falling straight pipe. A number of plug holes are evenly arranged on the outer wall of the collision straight pipe. A rectangular blocking block is inserted into each plug hole, which can meet the needs of steel balls of different specifications for diversion detection, ensure the smooth progress of the steel ball drop test, and can be used for steel balls with different diameter ranges for drop tests and complete the transmission action through the spiral hoist.

[0004] During the actual operation of the above-mentioned detection equipment, when the steel ball collides with the product, there is a probability that the steel ball will be stuck at the broken part of the product, resulting in the steel ball being unable to move to the inlet of the spiral elevator for recovery, and the release accuracy of the falling straight pipe is poor. If the steel ball needs to be released after being adsorbed by an electromagnetic suction cup, it is still necessary to manually adsorb and load the steel ball. Summary of the invention

[0041] In actual application, this embodiment has a relative first direction x, a second direction y and a third direction z. The xoy plane is assumed to be a horizontal plane. When the wear-resistant steel ball drop machine is used for experiments, the base 101 and the side bracket 104 are configured to be fixedly arranged on the flat ground end. The support 203 at the bottom of the collision chamber 201 is rotatably assembled on the base 101. When the oblique push block 204 at the bottom of the collision chamber 201 is movably pressed on the base 101, so that the collision chamber 201 as a whole maintains a horizontal posture, the clamp 202 is configured to load the product to be tested, the positioning column 301 is fixedly assembled on the side bracket 104 along the third direction z, and the screw rod 302 is rotatably assembled on the side bracket 104, and the bottom of the screw rod 302 is configured with a sub-driver that drives it to rotate independently to control the number of rotations of the screw rod 302, thereby adjusting the movement position of the detection frame 303 in the third direction z, and a slide cylinder 304 is elastically inserted at one end of the detection frame 303, and the electromagnetic suction cup 305 at the bottom of the slide cylinder 304 is in the power-on state. The ball guide tube 407 is provided at one side of the top of the positioning column 301, and the ball guide tube 401 is connected to the lifting member 5, so that the steel ball recovered in the lifting member 5 can be transported to the first ball guide tube 403 through the ball guide tube 401. Since one end of the first ball guide tube 403 is rotatably connected to the ball guide tube 401, the other end of the first ball guide tube 403 is rotatably connected to the second ball guide tube 404 through the rotating ring 405, and one end of the ball guide tube 407 is connected to the second ball guide tube 404 through the rotating ring 405. It is fixedly connected to the detection frame 303, and the other end of the ball guide catheter 407 is rotatably connected to the second ball guide tube 404. Therefore, when the detection frame 303 moves in the third direction z, the goal catheter 401 and the ball guide catheter 407 are always movably connected and interconnected, so that the steel ball transported to the goal catheter 401 via the lifting component 5 can pass through the first ball guide tube 403, the second ball guide tube 404, the rotating ring 405, the ball guide catheter 407 and the side rotation catheter 408 and then roll into the pre-installed catheter 411 for storage.When the electromagnetic suction cup 305 is powered off, the steel ball at its bottom loses its magnetic force in the third direction z and, under the action of gravity, vertically collides with the product on one side of the clamp 202. When the collision is completed, the locking plate 706 rotates around its fixed axis under the driving action, so that the locking groove 707 at one end of the locking plate 706 rotates away from the locking plate 701. At this time, the locking plate 701 elastically abuts against the sliding rod 704 and rotates counterclockwise in the xoz plane, so that the locking plate 701 pulls the collision chamber 201 to rotate around the fixed axis on the support 203 side during the movement, and the collision chamber 201 rotates counterclockwise in the xoz plane synchronously, so that when the collision chamber 201 is tilted, the fallen steel ball can roll under the component force of gravity, and the steel ball rolls away from the product and moves into the cavity of the collision chamber 201, so that the steel ball can roll to the side of the lifting component 5 for collection. When the experiment is completed, the lifting component 5, under the action of driving, transports the fallen steel ball to the goal guide tube 401, and makes the steel ball pass through the first ball guide tube 403, the second ball guide tube 404, the rotating ring 405, the ball guide tube 407 and the side rotation tube 408 again, and then rolls into the pre-installed tube 411 for storage. While the lifting component 5 transports the steel ball, the locking plate 701, under the action of driving, rotates clockwise along the xoz plane, so that the locking plate 701 squeezes the spring on one side of the slide rod 704, and is locked on the locking plate 706 again. At the same time, the pre-installed tube 411 can be controlled to output a single steel ball to the bottom of the electromagnetic suction cup 305, so that the electromagnetic suction cup 305 can position and adsorb the steel ball again after power is turned on, so that the steel ball drop machine can automatically collect and pre-load the fallen steel balls at any test height, and transport the steel balls to one side of the electromagnetic suction cup 305 for automatic positioning and adsorption.

[0042] See also Figure 2 In a preferred embodiment of the present invention, the base component 1 also includes a guide rod 102, an L-shaped frame 103 and a pulling rod 105, the guide rod 102 is fixedly arranged on the base 101, one end of the L-shaped frame 103 is slidably connected to the guide rod 102, and the other end of the L-shaped frame 103 is movably abutted on the inclined push block 204, one end of the pulling rod 105 is fixedly connected to the L-shaped frame 103, and the other end of the pulling rod 105 is movably abutted against the locking plate 701.

[0043] In actual application of this embodiment, the guide rod 102 is fixedly arranged on the base 101 along the first direction x, and the L-shaped frame 103 is elastically slidably assembled on the guide rod 102. When the L-shaped frame 103 moves along the negative direction of the first direction x under the pushing action of the pulling rod 105, the L-shaped frame 103 can push the collision chamber 201 to rotate counterclockwise around the fixed axis on the side of the support 203 in the xoz plane when abutting against the oblique push block 204, so that the collision chamber 201 is tilted as a whole. At this time, the steel ball dropped on the surface of the product rolls toward the side of the support 203 under the action of the gravity component force, so that the steel ball is separated from the product to prevent the steel ball from being stuck at the broken part of the product.

[0044] See also Figure 2 and Figure 5 In a preferred embodiment of the present invention, the collision chamber assembly 2 also includes a seam baffle plate 205, a guide hole 206 and a rail frame 207, the seam baffle plate 205 is fixedly arranged inside the cavity of the collision chamber 201, and the seam baffle plate 205 is tiltedly arranged in the collision chamber 201, the guide hole 206 is arranged at the end of the seam baffle plate 205, the rail frame 207 is arranged at the bottom of the collision chamber 201, the rail frame 207 is fixedly connected to the collision chamber 201, and the rail frame 207 is communicated with the guide hole 206.

[0045] In actual application of this embodiment, the seam baffle plate 205 is tiltedly arranged in the collision chamber 201. When the steel ball dropped on the surface of the product rolls toward the side of the support 203 under the action of the gravity component, the steel ball can continue to roll toward the side of the guide hole 206 along the inclined surface of the seam baffle plate 205 when it abuts against the seam baffle plate 205. When the steel ball moves to the side of the guide hole 206, it can pass through the guide hole 206 and fall into the rail frame 207, and roll along the rail frame 207 to the side of the lifting component 5, so that the steel ball is transported to the goal guide tube 401 through the lifting component 5.

[0046] Furthermore, a gap is set between the seam baffle 205 and the bottom of the collision chamber 201, and the gap width is smaller than the diameter of the steel ball, so that when the collision chamber 201 is tilted in the xoz plane, the fragments generated by the impact on the product surface can slide out through the bottom gap of the seam baffle 205, and the steel ball rolls along the inclined wall to the guide hole 206, and when the steel ball rolls in the rail frame 207, the debris attached to the surface of the steel ball can be centrifugally dropped to prevent the debris from scratching the surface of the steel ball.

[0047] See also Figure 4In a preferred embodiment of the present embodiment, the detection frame assembly 3 also includes a first oil pump barrel 306, a trigger rod 307, an oil pump pipe 308, a linkage frame 309 and a damper 310, the first oil pump barrel 306 is fixedly arranged on the detection frame 303 and the first oil pump barrel 306 is connected with the oil pump pipe 308, one end of the trigger rod 307 is limitedly slidably inserted in the first oil pump barrel 306, and the other end of the trigger rod 307 is fixedly connected to the linkage frame 309, the linkage frame 309 is movably connected to the slide cylinder 304, and a damper 310 is also arranged on one side of the linkage frame 309.

[0048] In actual application of this embodiment, hydraulic oil is pre-installed in the first oil pump barrel 306 and the oil pump pipe 308, and the piston at the end of the trigger rod 307 is inserted in the first oil pump barrel 306, so that when the trigger rod 307 slides along the first direction x, the hydraulic oil in the first oil pump barrel 306 is pumped in the oil pump pipe 308, and when a steel ball is adsorbed on one side of the electromagnetic suction cup 305, the electromagnetic suction cup 305 pulls the slide cylinder 304 to move synchronously in the negative direction of the third direction z under the action of gravity, so that the The trigger rod 307 moves in the negative direction of the first direction x under the pushing action of the linkage frame 309. At this time, the hydraulic oil in the first oil pump barrel 306 can be pumped out along the oil pump pipe 308. When the steel ball on one side of the electromagnetic suction cup 305 is detached, the slide cylinder 304 and the electromagnetic suction cup 305 move in the positive direction of the third direction z, so that the linkage frame 309 pulls the trigger rod 307 to move in the positive direction of the first direction x, thereby pumping the hydraulic oil in the oil pump pipe 308 into the first oil pump barrel 306.

[0049] Furthermore, the damper 310 can limit the sliding speed of the trigger rod 307 so that the steel ball can trigger the tilting of the collision chamber 201 after landing, thereby avoiding interference with the collision process.

[0050] See also Figure 6 and Fig.10 In a preferred embodiment of the present invention, the catheter assembly 4 also includes a tube support 406, a deflection wheel 409, a deflection synchronous belt 410 and a release groove 412, one end of the tube support 406 is fixedly connected to the detection frame 303, and the other end of the tube support 406 is fixedly connected to the ball guide catheter 407, one end of the deflection wheel 409 is rotatably set on the tube support 406, and the other end of the deflection wheel 409 is transmission-connected to the side-rotating catheter 408 through the deflection synchronous belt 410.

[0051] In actual application of this embodiment, the tube bracket 406 is fixedly assembled on one side of the detection frame 303 and the other end is fixedly connected to the ball guide tube 407. The side rotation tube 408 is rotatably assembled at the bottom of the ball guide tube 407 and is connected to the ball guide tube 407, so that when the steel ball rolling along the first ball guide tube 403, the second ball guide tube 404 and the rotating ring 405 falls into the ball guide tube 407, it can roll along the inner cavity of the ball guide tube 407 to the side rotation tube 408. The rotating catheter 408 is elastically rotatably assembled at the bottom of the ball guide catheter 407. Therefore, when the side rotating catheter 408 rotates toward the side of the detection frame 303, the pre-installed catheter 411 loaded with a plurality of steel balls at the end thereof can be synchronously rotated toward the side of the detection frame 303. The deflection wheel 409 is rotatably assembled on the pipe bracket 406, and the deflection synchronous belt 410 on the deflection wheel 409 is transmission-connected with the side rotating catheter 408, and the rotation of the deflection wheel 409 can drive the side rotating catheter 408 to rotate on a fixed axis.

[0052] See also Fig.10 In a preferred embodiment of the present invention, the catheter assembly 4 also includes a pre-installed groove 413, a closed bracket 414, a blocking baffle 415, an L-shaped rod 416 and a triangular rod 417. The pre-installed groove 413 is arranged at the end of the pre-installed catheter 411, and the closed bracket 414 is fixedly arranged on one side of the release groove 412. The blocking baffle 415 is elastically rotatably assembled on the closed bracket 414. The two ends of the blocking baffle 415 are respectively provided with a first blocking baffle a1 and a second blocking baffle a2. One side of the rotating shaft of the blocking baffle 415 is also fixedly connected with an L-shaped rod 416. One end of the triangular rod 417 is fixedly assembled on the detection frame 303, and the other end of the triangular rod 417 is movably abutted against the L-shaped rod 416.

[0053] In actual application of this embodiment, the pre-installed groove 413 is arranged at the end of the closed bracket 414, and the notch heights at both ends of the pre-installed groove 413 are smaller than the notch heights on the release groove 412 side, so that when the steel ball rolls to one side of the pre-installed groove 413 and is adsorbed on the electromagnetic suction cup 305, when the side-rotating catheter 408 moves in the reverse direction under the action of the elastic force, the pre-installed groove 413 on one side of the side-rotating catheter 408 moves in the reverse direction synchronously, and at this time, the steel ball can slide out of the pre-installed groove 413 from the low-position notch side of the pre-installed groove 413. Since the blocking baffle 415 is elastically rotatably assembled on the closed bracket 414, and in the default state, the blocking second baffle a2 at one end of the blocking baffle 415 is by default crimped in the release groove 412 to prevent a number of steel balls from moving along the pre-installed catheter. 411 rolls into the pre-installed groove 413, when the side-rotating guide tube 408 drives the pre-installed guide tube 411 to rotate toward the side of the detection frame 303, when the L-shaped rod 416 on one side of the blocking baffle 415 abuts against the triangular rod 417, the L-shaped rod 416 drives the blocking baffle 415 to rotate during the pushing process, so that the blocking second baffle a2 is rotated and disengaged from the release groove 412, and at the same time, the blocking first baffle a1 is rotated and crimped into the release groove 412, and in this process, the blocking first baffle a1 blocks the remaining steel balls and releases the limit of the steel ball at the bottom of the blocking baffle 415, and the steel ball rolls along the pre-installed guide tube 411 to the pre-installed groove 413, so that the steel ball in the pre-installed groove 413 can move to the bottom of the electromagnetic suction cup 305 to wait for positioning and adsorption.

[0054] Furthermore, when the side-rotating catheter 408 rotates in the opposite direction under the elastic force and the tube bracket 406 rotates out of the side of the ball-guiding catheter 407, the second blocking baffle a2 can be re-inserted into the release groove 412 and the first blocking baffle a1 can be rotated out of the release groove 412. At this time, several steel balls roll synchronously and are synchronously limited to one side of the second blocking baffle a2 to realize the pre-loading of the steel balls.

A lifting synchronous belt 503 is installed between the two groups of the lifting main shafts 502, and a plurality of ball guide groove frames 504 are arranged on the outer surface of the lifting synchronous belt 503.

[0056] When this embodiment is actually used, the two sets of lifting spindles 502 arranged on the hoist side plate 501 can drive the lifting synchronous belt 503 to make unidirectional movement in the driving state. The ball guide groove frame 504 on the surface of the lifting synchronous belt 503 is in the shape of a groove, which can make the steel ball rolling out of the track frame 207 fall into the groove and follow the ball guide groove frame 504 to move in the positive direction of the third direction z. The groove is also inclined so that the steel ball in the groove always rolls to one side. A connected ball return track 402 is arranged between the goal guide tube 401 and the hoist side plate 501. When the steel ball climbs to the height of the ball return track 402 with the ball guide groove frame 504, the steel ball can roll along the inclined groove to the ball return track 402, and move along the ball return track 402 to the goal guide tube 401, thereby completing the lifting action of the steel ball.

When the residual teeth on the residual tooth gear 608 rotate to the side of the third transmission gear 609, it can mesh and drive the third transmission gear 609 to rotate, so that the fourth transmission gear 610 at the end of the third transmission gear 609 synchronously drives the deflection wheel 409 to move, so that during the rotation of the third transmission shaft 605, the side rotation catheter 408 rotatably assembled on one side of the detection frame 303 can rotate synchronously.

[0059] See also Figure 7 In a preferred embodiment of the present invention, the transmission assembly 6 also includes a driving disk 611, an inclined wall block 612 and a main driving shaft 613, one end of the driving disk 611 is coaxially fixedly connected to the third transmission shaft 605, the other end of the driving disk 611 is provided with an inclined wall block 612, the inclined wall block 612 is movably abutted against the sliding rod 704, one end of the main driving shaft 613 is drivingly connected to the third transmission shaft 605, and the other end of the main driving shaft 613 is drivingly connected to any one of the lifting main shafts 502.

[0060] In actual application of this embodiment, the main drive shaft 613 is connected to an external drive source, and the specific structure of the drive source is not limited. When the main drive shaft 613 rotates around a fixed axis, it can drive any lifting main shaft 502 and the third transmission shaft 605 to rotate through the transmission structure. During the rotation, the third transmission shaft 605 can also drive the drive disk 611 at one end thereof to rotate clockwise in the yoz plane, so that the inclined wall block 612 on one side of the drive disk 611 slides and abuts against the slide bar 704 during the rotation, and can press the slide bar 704 to move in the negative direction of the first direction x, thereby pushing the locking plate 701 toward the side of the locking plate 706 through the slide bar 704, so that the locking plate 701 is limited and clamped in the locking groove 707.

[0061] See also Fig.12In a preferred embodiment of the present invention, the locking assembly 7 also includes a trigger plate 708, a second oil pump barrel 709, a trigger pump rod 710 and a pump rod piece 711. The trigger plate 708 is limitedly rotated and assembled on the locking plate 706. One end of the second oil pump barrel 709 is fixedly assembled on the tail bracket 702.

The end of the trigger pump rod 710 is fixedly connected with the pump rod piece 711, and the pump rod piece 711 is movably abutted against the trigger plate 708.

[0062] In actual application of this embodiment, the second oil pump barrel 709 is connected to the oil pump pipe 308, and the second oil pump barrel 709 is filled with hydraulic oil. The piston at one end of the trigger pump rod 710 is slidably inserted into the second oil pump barrel 709. When the steel ball on one side of the electromagnetic suction cup 305 falls off, the trigger rod 307 moves in the positive direction of the first direction x, so that the hydraulic oil pump in the oil pump pipe 308 is sucked into the first oil pump barrel 306. At the same time, the hydraulic oil pump in the second oil pump barrel 709 is sucked into the oil pump pipe 308, so that the trigger pump rod 710 pulls the pump rod piece 711 to move synchronously along the negative direction of the first direction x. When the pump rod piece 711 is crimped onto the trigger plate 708, since the trigger plate 708 is limitedly rotated and assembled on the locking plate 706, the pump rod piece 711 can push the trigger plate 708 and the locking plate 706 rotate clockwise as a whole in the xoz plane, so that the locking slot 707 slides out of one side of the locking plate 701, and the locking plate 701 rotates around the fixed axis under the push of the elastic force, and simultaneously pushes the pulling rod 105 to move in the negative direction of the first direction x, so that the pulling rod 105 pulls the L-shaped frame 103 to move along the negative direction of the first direction x, thereby causing the collision chamber 201 to rotate and tilt. When the locking plate 706 rotates around the fixed axis at a fixed angle, the pump rod sheet 711 slides out of the end of the trigger plate 708, so that the locking plate 706 is reset and attached to the limit bracket 705 under the action of the elastic force. At this time, the driving disk 611 can use the inclined wall block 612 to push the sliding rod 704 to slide during the rotation process, so as to push the locking plate 701 to be buckled and locked in the locking slot 707 again.

[0063] The specific implementation steps of this embodiment are as follows:

[0064] S1: The steel ball adsorbed on the electromagnetic suction cup 305 falls off, and the electromagnetic suction cup 305 is displaced to trigger the locking plate 706, so that the locking plate 701 drives the collision chamber 201 to flip in the loose state, and the fallen steel ball rolls along the rail frame 207 to the ball guide groove frame 504;

[0065] S2: The main drive shaft 613 rotates a fixed number of times under the drive of the controller, and when the third transmission shaft 605 is driven to rotate, the driving disc 611 pushes the sliding rod 704 to make the locking plate 701 buckle and lock in the locking groove 707;

[0066] S3: The third transmission shaft 605 drives the side-rotating catheter 408 to rotate while rotating, so that the pre-loaded catheter 411 loaded with pre-loaded steel balls rotates close to the electromagnetic suction cup 305, and outputs a steel ball to be positioned and adsorbed on the electromagnetic suction cup 305;

[0067] S4: the driving force on one side of the side-rotating catheter 408 disappears, so that the side-rotating catheter 408 rotates in the opposite direction and resets under the elastic force. At this time, the bottom of the electromagnetic chuck 305 absorbs the steel ball to be released, and the pre-loaded catheter 411 begins to be pre-loaded with steel balls;

[0068] S5: The main drive shaft 613 rotates a fixed number of times under the drive of the controller, driving the lifting main shaft 502 to rotate, so that the steel ball that has rolled onto the ball guide groove frame 504 is lifted in the third direction z, and the steel ball is released into the ball guide tube 401;

[0069] S6: Repeat the above steps.

It can automatically recover the steel ball after the collision at any height position according to the release action of the steel ball, and lift the recovered steel ball to the catheter assembly 4 for pre-loading, so that the electromagnetic suction cup 305 can automatically position and adsorb the steel ball.
