[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figure 1-4 As shown, a burr removal device includes a base 1 and a gantry 4 fixed to the top of the base 1 by bolts, the top of the base 1 is provided with two sets of clamping mechanisms 2 for clamping a plastic ball and driving the plastic ball to rotate, a grinding mechanism 5 for grinding and deburring the rotating plastic ball is provided below the top of the gantry 4, the grinding mechanism 5 includes a hard arc block 7 and an arc support plate 9, the arc support plate 9 is composed of a plurality of mounting blocks 11 movably connected by a thin-walled rotatable area 12, a plurality of brushes 10 are fixed on the inner side of each of the mounting blocks 11, and the outer side of each of the mounting blocks 11 is connected to the hard arc block 7 by a rubber connecting rod 8.

[0033] When the device is used, the plastic ball can be clamped by the clamping mechanism 2 and driven to rotate at high speed, and then the grinding mechanism 5 is brought close to and fits the surface of the plastic ball, and the burrs on the surface of the plastic ball can be rubbed and removed by the pressure generated when the brush 10 contacts the surface of the plastic ball.

[0034] The device, by providing an arc-shaped arc support plate 9, and arranging a brush 10 on the inner side thereof, and clamping the plastic ball with a clamping mechanism 2 and rotating it at high speed, can reliably remove burrs from the curved surface of the plastic ball. In addition, the device combines the arc support plate 9 with a position mounting block 11 and a thin-walled rotatable area 12, and the arc support plate 9 is connected to the hard arc block 7 by a rubber connecting rod 8, so that the shape of the arc support plate 9 itself can change slightly in curvature when it fits the surface of the plastic ball, and reliably fits the surface of the plastic ball to ensure the grinding effect. In addition, it can also adaptively grind within a certain diameter range.

[0035] In this embodiment, the clamping mechanism 2 includes an inwardly concave arc-surface chuck 14, a connecting shaft 15 and a transverse plate 17. The concave curvature of the inwardly concave arc-surface chuck 14 matches the spherical surface of the plastic ball to be processed, and the outer side surface of the inwardly concave arc-surface chuck 14 is rotatably connected to the transverse plate 17 through the connecting shaft 15. The transverse plate 17 is slidably connected to the upper surface of the base 1 through a linear slide rail 18.

[0036] In this embodiment, a motor 16 is fixed to an outer wall of one side of the gantry 4 by bolts, and the output shaft of the motor 16 is connected to a screw rod 19 through a coupling, and the screw rod 19 is respectively connected with the two transverse plates 17 by threads with opposite rotation directions.

[0037] When the motor 16 is started, the screw rod 19 can be driven to move, thereby driving the two transverse plates 17 to move relative to each other through the threaded connection, thereby driving the concave arc-shaped chucks 14 to move relative to each other, thereby achieving the clamping and loosening of the plastic ball.

[0038] In this embodiment, the clamping mechanism 2 further includes a rotation drive component 3. In this embodiment, the specific type of the rotation drive component 3 is not limited, and it can be directly driven by a rotation drive component such as an electric motor, a pneumatic motor, or a hydraulic motor.

[0039] In this embodiment, the hard arc block 7 is slidably connected to the gantry 4 through the guide slide 6, and the bottom side of the guide slide 6 is rotatably connected to the connecting rod 13, and the other end of the connecting rod 13 is rotatably connected to the top side of the transverse plate 17; when in the clamping process, when the two transverse plates 17 are close to each other, the connecting action of the connecting rod 13 can make the guide slide 6 drive the grinding mechanism 5 to descend, and when the grinding is completed and in the separation step, the transverse plates 17 are separated from each other and the guide slide 6 rises.

[0040] By setting the connecting rod 13, the present device can, on the one hand, integrate the lifting power source of the guide slide rod 6 with the clamping power source of the transverse plate 17, thereby reducing the power source layout and reducing costs. On the other hand, it can also make the position of the grinding mechanism 5 correspond to the clamping state of the plastic ball by the concave arc chuck 14, thereby increasing the synchronization of the movements of the entire device and improving the use efficiency.

[0041] In this embodiment, when in use, the plastic ball is clamped between the two concave arc-surface chucks 14, and the motor 16 is started, so that the motor 16 drives the screw 19 to rotate, and drives the two transverse plates 17 to move closer to each other. On the one hand, the two transverse plates 17 drive the concave arc-surface chucks 14 to move closer to each other to clamp the plastic ball. On the other hand, when the transverse plates 17 move closer to each other, the connecting rod 13 drives the guide slide bar 6 to descend, thereby driving the grinding mechanism 5 to descend and fit the surface of the plastic ball, and then the concave arc-surface chuck 14 is driven to rotate through the rotating drive component 3, thereby driving the plastic ball to rotate, and the contact pressure between the plastic ball and the brush 10 is used to remove the burrs.

[0042] Embodiment 2:

[0043] A burr removal device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1-4 As shown, the rotary drive assembly 3 includes a motor 20 and a sleeve 21. The motor 20 is fixed to the side wall of the gantry 4 by bolts, and the sleeve 21 is fixed to the side wall of the connecting shaft 15 by bolts. A spline head 23 is welded on the end face of the output shaft of the motor 20, and a spline groove 22 cooperating with the spline head 23 is provided at the end of the sleeve 21 away from the connecting shaft 15.

[0044] The axes of the output shaft of the second motor 20, the sleeve 21 and the connecting shaft 15 coincide with each other.

[0045] In the present embodiment: when the two transverse plates 17 are not close to each other, the transverse plates 17 are relatively fitted to the gantry 4, the spline head 23 and the spline groove 22 do not match, and the transmission chain of the motor 20-connecting shaft 15 is disconnected. When the transverse plates 17 are close to each other and clamped, the spline head 23 is inserted into the spline groove 22 to achieve engagement. At this time, the motor 20 starts the interface to drive the connecting shaft 15 to rotate.

[0046] The device realizes the disconnection and connection of the transmission chain from the motor 20 to the connecting shaft 15 by setting the spline groove 22 and the spline head 23 and utilizing the position characteristics of the transverse plate 17 for the clamping and non-clamping states of the plastic ball, thereby preventing the motor 20 from starting and driving other components to rotate highly in the non-clamping state, thereby posing a safety hazard.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
