DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment 1
[0023] See also Figures 1-4 A ball filling device for a ball screw comprises a bottom plate 1 and a supporting leg 2, a raw material box 3 is arranged above the supporting leg 2, a discharge plate 4 is connected to one side of the raw material box 3, a rotatable feeding column 5 is arranged on one side of the discharge plate 4, a plurality of transfer grooves 6 are opened on the outer wall of the feeding column 5, a guide plate 7 is fixedly installed on the top surface of the bottom plate 1, and the guide plate 7 is located on one side of the transfer groove 6.
[0024] For further information, see Figures 1-2 A square plate is fixedly installed on the top surface of the supporting leg 2, and the raw material box 3 is fixedly installed on the top surface of the square plate. The bottom of the inner wall of the raw material box 3 is inclined. A loading plate 14 is fixedly installed on the side wall of the square plate. A servo motor 15 is fixedly installed on one side of the loading plate 14. The servo motor 15 is connected to the transfer slot 6. By setting the bottom of the inner wall of the raw material box 3 to be inclined, the user can place the ball in the raw material box 3 and slide it into the discharge plate 4 through the inclined raw material box 3.
[0025] For further information, see Figure 2 A plurality of partition plates are fixedly installed inside the transfer groove 6, and the plurality of partition plates are arranged at equal intervals. By setting the partition plates, the balls will not move laterally over a large range after entering the transfer groove 6.
[0026] During the specific implementation, the user needs to place a large number of balls directly into the raw material box 3 at one time. After the balls are placed in the raw material box 3, the balls will slide directly into the discharge plate 4. When the balls directly contact the outer wall of the feeding column 5, they will stop moving until the user starts the servo motor 15. After the servo motor 15 is started, the feeding column 5 starts to rotate. During the rotation of the feeding column 5, the balls hanging in the discharge plate 4 will fall into the transfer groove 6 opened on the outer wall of the feeding column 5, and then be driven to move by the rotating feeding column 5 until the transfer groove 6 tilts downward again. Only then will the balls in the transfer groove 6 fall and fall into the guide plate 7. The user can place the screw rod to be filled in the positioning groove 9 in advance to facilitate the balls in the guide plate 7 to fall into the screw rod, thereby completing the automatic loading of the screw rod.
[0027] By setting a feeding column 5, opening a transfer groove 6 on the outer wall of the feeding column 5, setting a raw material box 3 and a discharge plate 4 on one side of the feeding column 5, setting a guide plate 7 on the other side of the feeding column 5, and finally placing a screw rod under the guide plate 7, the automatic loading work in the ball filling work can be completed, so that the relevant staff do not need to manually fill the balls, thereby improving the overall work efficiency.
[0028] Embodiment 2
[0029] Based on Example 1, please refer toFigures 1-4 , a ball filling device for a ball screw, wherein a movable limiting plate 8 is arranged on the top surface of a square plate, a moving block 10 is fixedly installed on one side of the limiting plate 8, a mounting plate 11 is fixedly installed on the side wall of the square plate, a rotatable bidirectional screw rod 12 is connected to one side of the mounting plate 11, and the moving block 10 is threadedly connected to the outer wall of the bidirectional screw rod 12.
[0030] Further, referring to Figures 1-4 , the specific numbers of the limiting plate 8 and the moving block 10 are both two, and the two limiting plates 8 and the moving blocks 10 are symmetrically arranged in the initial state. By setting two, the two limiting plates 8 and the moving blocks 10 are symmetrically arranged in the initial state, so that during the rotation of the bidirectional screw rod 12, the two moving blocks 10 will move away from or towards each other.
[0031] In addition, a rotatable knob 13 is installed on the outer wall of the mounting plate 11, and the knob 13 is fixedly connected to the bidirectional screw rod 12. By setting the knob 13, the rotation of the bidirectional screw rod 12 can be controlled by the knob 13, and the rotation of the bidirectional screw rod 12 can be completed more easily.
[0032] During specific implementation, since the filling speeds of each person are different, if the ball screw 5 drops too many balls at one time, it will directly affect the operation of the relevant staff and also slow down the efficiency.
[0033] In this utility model, when the user feels that the device drops too many balls at one time, the user can rotate the knob 13. After the knob 13 rotates, it will drive the bidirectional screw rod 12 to rotate. During the rotation of the bidirectional screw rod 12, the two moving blocks 10 symmetrically threadedly connected to the outer wall of the bidirectional screw rod 12 will move away from or towards each other. And the limiting plate 8 is fixedly connected to one side of the moving block 10, so the limiting plate 8 will also move synchronously. And the limiting plate 8 is integrally "U"-shaped and is arranged on the outer wall of the ball screw 5, isolating the butt joint between the ball screw 5 and the discharge plate 4. Therefore, after the two limiting plates 8 move towards each other, more outer wall area of the ball screw 5 will be blocked, so that the ball screw 5 cannot transport too many balls at one time.
[0034] Similarly, when the user feels that the feeding speed is too slow, the user can reverse the knob 13 to move the two limiting plates 8 away from each other, so that a larger outer wall area of the ball screw 5 is exposed, thereby increasing the feeding speed of the device.
[0035] By setting the limiting plate 8 and the moving block 10, and setting the moving block 10 threadedly connected to the outer wall of the bidirectional screw rod 12, the user can adjust the distance between the two limiting plates 8 by rotating the bidirectional screw rod 12, thereby adjusting the overall feeding speed of the device and making the application range of the device wider.
[0036] Working principle: The user needs to directly place a large number of ball bearings into the raw material box 3 at one time. After the ball bearings are placed in the raw material box 3, the ball bearings will directly slide into the discharge plate 4. When the ball bearings directly contact the outer wall of the feeding column 5, they will stop moving forward until the user starts the servo motor 15. After the servo motor 15 is started, the feeding column 5 starts to rotate. During the rotation of the feeding column 5, the ball bearings perpendicular to the discharge plate 4 will fall into the transfer groove 6 opened on the outer wall of the feeding column 5, and then be driven by the rotating feeding column 5 to move. Until the transfer groove 6 tilts downward again, the ball bearings in the transfer groove 6 will fall and fall into the guide plate 7. The user can place the lead screw to be filled in the positioning groove 9 in advance, which is convenient for the ball bearings in the guide plate 7 to fall into the lead screw, completing the automatic feeding of the lead screw ball filling.
[0037] Since the loading speed of each person is different, if the feeding column 5 drops too many ball bearings at one time, it will directly affect the operation of the relevant staff and also slow down the efficiency.
[0038] In this utility model, when the user feels that the device drops too many ball bearings at one time, the knob 13 can be rotated. After the knob 13 rotates, it will drive the bidirectional lead screw 12 to rotate. During the rotation of the bidirectional lead screw 12, the two moving blocks 10 symmetrically thread-connected to the outer wall of the bidirectional lead screw 12 will move away from or towards each other. And the limiting plate 8 is fixedly connected to one side of the moving block 10, so the limiting plate 8 will also move synchronously. The overall shape of the limiting plate 8 is "U", and it is arranged on the outer wall of the feeding column 5, isolating the connection between the feeding column 5 and the discharge plate 4. Therefore, after the two limiting plates 8 move towards each other, more of the outer wall area of the feeding column 5 will be blocked, making it impossible for the feeding column 5 to transport too many ball bearings at one time.
[0039] Similarly, when the user feels that the blanking speed is too slow, the knob 13 can be rotated in reverse to make the two limiting plates 8 move away from each other, so that a larger area of the outer wall of the feeding column 5 is exposed, thereby increasing the blanking speed of the device.
[0040] By setting the feeding column 5, opening the transfer groove 6 on the outer wall of the feeding column 5, setting the raw material box 3 and the discharge plate 4 on one side of the feeding column 5, setting the guide plate 7 on the other side of the feeding column 5, and finally placing the lead screw under the guide plate 7, the automatic feeding work in the ball filling work can be completed, enabling the relevant staff not to manually fill the ball bearings, improving the overall work efficiency.
[0041] By setting the limiting plate 8 and the moving block 10, and setting the moving block 10 thread-connected to the outer wall of the bidirectional lead screw 12, the user can adjust the distance between the two limiting plates 8 by rotating the bidirectional lead screw 12, thereby adjusting the overall blanking speed of the device and making the application range of the device wider.
