During the subsequent cladding process of the ball core 3, excess paint drips into the collection box 61 for collection, thereby preventing the paint from directly dripping into the surrounding environment and causing pollution to the surrounding environment. At the same time, waste of paint resources can be avoided.

[0026] Specifically, the abutting member 65 includes a abutting rod 651, an abutting block 652, a cavity 653 and a second spring 654. The interior of the bracket 5 is provided with a cavity 653, the interior of the cavity 653 is plugged with the abutting rod 651, the second spring 654 is connected between the abutting rod 651 and the cavity 653, and the abutting block 652 is connected to the side wall of the collection box 61 at a position corresponding to the abutting rod 651.

[0027] By adopting the above technical solution, the clamping rod 651 is moved into the cavity 653, and the clamping rod 651 moves to squeeze the second spring 654. After the collection box 61 is placed in the placement groove 62, the clamping rod 651 is released, and the second spring 654 loses the external force and returns to its original state, driving the clamping rod 651 to move and protrude out of the cavity 653. When the clamping rod 651 is moved and inserted into the abutment block 652, the clamping rod 651 continues to move to drive the collection box 61 to move and fit onto the side wall of the placement groove 62.

When the pressing rod 651 is moved and plugged into the abutment block 652, the pressing rod 651 continues to move and drives the collection box 61 to move and fit onto the side wall of the placement groove 62, and then the ball core 3 is placed on the periphery of the pushing mechanism 1 and the rotating mechanism 4, and then the ball core 3 is subjected to a cladding operation. During the cladding process, excess paint drips into the collection box 61 for collection, so as to avoid the paint dripping into the surrounding environment and causing pollution to the surrounding environment, and at the same time, it can avoid waste of paint resources.

[0031] Example 2

[0032] The present embodiment is different from the embodiment 1 in that: the connection assembly 2 comprises a connection box 21, a first spring 22, an arc-shaped connection plate 23, an end block 24, a rotating screw 25 and a through hole 26; the connection box 21 is connected to the outer wall of the push mechanism 1; both ends of the connection box 21 are connected to the rotating screw 25; both sides of the interior of the connection box 21 are provided with an arc-shaped connection plate 23; both ends of the arc-shaped connection plate 23 are connected to the end block 24; the first spring 22 is connected between the connection box 21 and the end block 24; the side wall of the connection box 21 is provided with a through hole 26;

[0033] Specifically, a fixing column is connected to the inner wall of the connection box 21, a round hole is provided on the end block 24 at a position corresponding to the fixing column, and a limiting plate is connected to one end of the fixing column close to the end block 24.

[0034] By adopting the above technical solution, when the arc connecting plate 23 is moved by rotating the screw rod 25, the end block 24 moves along the fixed column under the action of the circular hole, providing a guide for the movement of the end block 24, and then providing a guide for the movement of the arc connecting plate 23, thereby improving the stability of the movement of the arc connecting plate 23, and when the end block 24 moves to fit the limit plate, the end block 24 is blocked and stops moving, thereby preventing the arc connecting plate 23 from continuing to move.

[0035] When this embodiment is used, the ball core 3 is sleeved on the periphery of the rotating mechanism 4, and then the pushing mechanism 1 is used to drive the connecting box 21. When the end of the rotating mechanism 4 passes through the through hole 26 and fits with the component of the pushing mechanism 1, the pushing mechanism 1 is stopped, and then the rotating screw 25 is rotated to make it rotate and move along the connecting box 21. The movement of the rotating screw 25 drives the arc-shaped connecting plate 23 to move, and the movement of the arc-shaped connecting plate 23 drives the end block 24 to move. The movement of the end block 24 drives the first spring 22 to stretch. When the arc-shaped connecting plate 23 is tightly fitted to the outer wall of the pushing mechanism 1 and the rotating mechanism 4 components, the rotation of the rotating screw 25 is stopped, so as to facilitate the sleeve connection and removal operation of the ball core 3.

[0036] The structure and principle of the pushing mechanism 1 composed of a cylinder, a jacket and a positioning shaft in the utility model have been disclosed in a small-diameter ball core cladding positioning processing tool disclosed in Chinese patent application No. 202221100261.7, and its working principle is: a cylinder is connected to the side wall of one of the brackets 5, and the output end of the cylinder is connected to the jacket, and the interior of the jacket is connected to the positioning shaft, and the other end of the positioning shaft is connected to the connecting box 21. When in use, the cylinder is used to drive the jacket to move, and the movement of the jacket drives the movement of the positioning shaft, and the movement of the positioning shaft can drive the connecting box 21 to move.

[0037] The structure and principle of the rotating mechanism 4 composed of a rotating device, a first positioning shaft, a second positioning shaft, a first support rod, a second support rod, a return spring, a first positioning boss, and a second positioning boss in the utility model have been disclosed in a small-diameter ball core cladding positioning processing tool disclosed in Chinese patent application No. 202221100261.7, and its working principle is: a rotating device is connected to the side wall of the bracket 5 away from the pushing mechanism 1, the output end of the rotating device is connected to the second positioning shaft, the first positioning shaft is arranged at one end of the second positioning shaft away from the bracket 5, the first positioning shaft is hinged on the side wall close to the second positioning shaft, and the second positioning shaft is hinged on the side wall of the second positioning shaft and at the position corresponding to the first support rod. Two support rods, the front end of the first support rod is hinged with the front end of the second support rod, and the first positioning boss and the second positioning boss are respectively provided at the ends of the first positioning axis and the second positioning axis close to each other, and a return spring is installed between the first positioning boss and the second positioning boss. When in use, the ball core 3 is sleeved on the periphery of the first support rod and the second support rod, and then the pushing mechanism 1 is used to push the first positioning axis to move similarly relative to the second positioning axis. While compressing the return spring, the hinged end between the first support rod and the second support rod is opened outward and pressed against the inner hole of the ball core 3, so that the inner hole of the ball core 3 is positioned and clamped at three points, and then the rotating device is used to rotate the second positioning axis to drive the ball core 3 to rotate, so that the ball core 3 can be clad.

[0038] The working principle and use process of the utility model are as follows: the utility model moves the clamping rod 651 into the cavity 653, and the clamping rod 651 moves to squeeze the second spring 654. After the collection box 61 is placed in the placement groove 62, the clamping rod 651 is released, and the second spring 654 loses the external force and restores its original appearance, driving the clamping rod 651 to move and protrude from the cavity 653. When the clamping rod 651 moves and is inserted into the abutment block 652, the clamping rod 651 continues to move to drive the collection box 61 to move and fit onto the side wall of the placement groove 62, and the ball core 3 is sleeved onto the periphery of the rotating mechanism 4. The pushing mechanism 1 is then used to drive the connecting box 21. When the end of the rotating mechanism 4 passes through the through hole 26 and fits with the component of the pushing mechanism 1 After that, stop operating the pushing mechanism 1, and then rotate the rotating screw 25 to make it rotate and move along the connecting box 21. The movement of the rotating screw 25 drives the arc-shaped connecting plate 23 to move, and the movement of the arc-shaped connecting plate 23 drives the end block 24 to move. The movement of the end block 24 drives the first spring 22 to stretch. When the arc-shaped connecting plate 23 is tightly fitted to the outer wall of the pushing mechanism 1 and the rotating mechanism 4, stop rotating the rotating screw 25 to facilitate the sleeve connection and taking operation of the ball core 3, and then perform the cladding operation on the ball core 3. During the cladding process, excess paint drips into the collecting box 61 for collection operation, which avoids the paint dripping into the surrounding environment and causing pollution to the surrounding environment. At the same time, it can avoid the waste of paint resources.
