[0024] Reference Figure 1-Figure 7A processing device for a dynamic seal includes a frame 1, two air holes 4 are provided on the top outer wall of the frame 1, two fans 3 are fixed to the top outer wall of the frame 1 by bolts, and the two fans 3 are located in the air holes 4, so that air circulates inside the frame 1 to improve the heat dissipation of the frame 1. A protective cover 5 is connected to the outer wall of one side of the frame 1 by a hinge to seal the frame 1 so that the debris generated by the chamfer of the pressure cover 33 will not fall out of the frame 1. The inner wall of one side of the frame 1 is welded with a The triangular bar 2 blocks the corner at the rear to prevent debris from getting stuck at the corner. The motor 13 is fixed to the inner wall of the top of the frame 1 by bolts. A mounting groove 14 is provided on the inner wall of the bottom of the frame 1. A turntable 15 that rotates coaxially with the motor 13 is rotatably connected in the mounting groove 14. A locking mechanism for fixing the pressure cover 33 is provided on the top of the turntable 15. The electric push rod 6 is fixed to the outer wall of the top of the frame 1 by bolts. The movable end of the electric push rod 6 is fixed to the mounting plate 8 by bolts. The mounting plate 8 is fixed to the outer wall of the frame 1 by bolts. The top is fixed with a guide frame 7 by bolts, and one end of the guide frame 7 passes through the frame body 1, and the guide frame 7 guides the movement of the mounting plate 8, making the movement of the mounting plate 8 more stable, and at the same time can provide an auxiliary supporting force for the mounting plate 8, so that the position of the mounting plate 8 is more accurate. The bottom of the mounting plate 8 is provided with a cutter head 11 for chamfering the pressure cover 33, and the cutter head 11 is connected to the mounting plate 8 by an adjusting component. The adjusting component is used to adjust the horizontal position of the cutter head 11. When in use, the pressure cover 33 is placed on the turntable 15 and fixed with a locking mechanism. The position of the cutter head 11 is changed by the adjusting component, and the motor 13 and the electric push rod 6 are started. The motor 13 drives the turntable 15 to rotate, thereby driving the pressure cover 33 to rotate. The extension of the electric push rod 6 will cause the mounting plate 8 and the cutter head 11 to move downward synchronously, and then chamfer the rotating pressure cover 33. Since the cutter head 11 is in a relatively static state, the chamfering accuracy of the equipment is more accurate, and the qualified rate of the pressure cover 33 is improved.

[0025] In order to fix the pressure cover 33, the locking mechanism of the present invention includes an inner cavity 16 opened in the turntable 15, the top of the inner cavity 16 is rotatably connected to the disc 17, the top of the disc 17 is provided with a plurality of extrusion grooves 18, the top of the turntable 15 is provided with a plurality of guide grooves 19, the guide grooves 19 are slidably connected with a moving block 21, the top of the moving block 21 is welded with a clamping frame 22, and the bottom is welded with a guide column 23 that slides in the extrusion groove 18, a power component for driving the disc 17 to rotate is provided on the inner wall of one side of the inner cavity 16, and the edge of the guide groove 19 at the top of the turntable 15 is opened. A scale 20 is provided, which is used in conjunction with a moving block 21. The pressure cap 33 is placed on the outer side of the circumference of one end of multiple clamps 22. The disc 17 is driven to rotate by the power component, so that the extrusion groove 18 squeezes the guide column 23 to drive the moving block 21 to slide in the guide groove 19, thereby pulling the clamp 22 to move outward, and then fixing the pressure cap 33, so that the pressure cap 33 can be driven to rotate by the turntable 15. Since the clamp 22 slides in the guide groove 19, the clamp 22 can clamp pressure caps 33 of different diameters, thereby improving the applicability of the equipment.

[0026] In order to drive the turntable 15 to rotate, the power assembly of the present invention includes an outer gear ring 24 fixed to the bottom of the disc 17 by bolts, and the bottom of the inner cavity 16 is connected to a gear 29 that meshes with the outer gear ring 24 through an axis rotation. The bottom of the gear 29 is welded with a turning handle 28 that is concentric with it. A counterweight block 25 is welded on one side of the turntable 15. The counterweight block 25 and the turning handle 28 are symmetrically distributed, so that the center of gravity of the turntable 15 remains concentric with the center, thereby improving the stability of the rotation of the turntable 15. The bottom of the inner cavity 16 is provided with a counter-rotating The limiting mechanism for auxiliary fixation of handle 28 and the resistance increasing mechanism for strengthening the limitation of the outer gear ring 24, turn the handle 28, the handle 28 drives the gear 29 to rotate, thereby driving the outer gear ring 24 to rotate, and then driving the disc 17 to rotate. The gear 29 and the outer gear ring 24 are in a deceleration motion, so that the rotation of the disc 17 is more precise, and the labor-saving effect of the equipment is improved. After rotation, the handle 28 will be fixed by the limiting mechanism, so that the position of the disc 17 is fixed, and the fixation of the pressure cover 33 is more stable.

[0027] In order to fix the turning handle 28, the limiting mechanism in the present invention includes a placement groove 31 opened at the bottom of the inner cavity 16, and an elastic ball 32 is bonded in the placement groove 31. A plurality of arc-shaped grooves 30 are opened at the bottom of the turning handle 28, and the elastic ball 32 is located in one of the arc-shaped grooves 30. When the turning handle 28 is rotated, the arc-shaped groove 30 will squeeze the elastic ball 32 and deform it, so that the elastic ball 32 moves out of the current arc-shaped groove 30 and then moves to another adjacent arc-shaped groove 30. The elastic ball 32 is located in the arc-shaped groove 30, which can fix the current position of the turning handle 28, avoid the turning handle 28 from rotating and loosening the fixation of the pressure cover 33, and improve the fixation stability of the pressure cover 33 during installation.

[0028] In order to assist in fixing the pressure cover 33 during the rotation process, the resistance-increasing mechanism in the present invention includes a plurality of elastic rubber blocks 27 bonded to the inner wall of the circumference of the inner cavity 16, and an arc-shaped strip 26 in contact with the outer gear ring 24 is bonded to one side of the elastic rubber block 27. The rotating turntable 15 will generate centrifugal force, thereby causing the elastic rubber block 27 to extend and deform outward, thereby causing the arc-shaped strip 26 to squeeze the outer gear ring 24, increasing the friction between the outer gear ring 24 and the arc-shaped strip 26, making the outer gear ring 24 less likely to rotate, and improving the fixing stability of the pressure cover 33 when chamfering.

[0029] In order to change the position of the cutter head 11, the adjustment component in the present invention includes a slide groove 9 opened at the bottom of the mounting plate 8, and a slider 12 fixed to the cutter head 11 is slidably connected in the slide groove 9, and a threaded rod 10 is rotatably connected to the inner wall of one side of the slide groove 9. One end of the threaded rod 10 passes through the slider 12 and the mounting plate 8, and the threaded rod 10 is threadedly connected to the slider 12. By rotating the threaded rod 10, the slider 12 moves in the slide groove 9 under the action of the thread, and then drives the cutter head 11 to move, thereby changing the distance between the cutter head 11 and the center of the turntable 15, so as to adapt to pressure caps 33 of different diameters. Only one cutter head 11 is needed to complete pressure caps 33 of multiple diameters, reducing the factory's investment cost and further improving the applicability of the equipment.

[0030] The working principle of the present invention is as follows: when in use, the protective cover 5 is opened, the pressure cover 33 is put on the outer circumference of one end of the multiple clamping frames 22, and the turning handle 28 is turned. The turning handle 28 drives the gear 29 to rotate, thereby driving the outer gear ring 24 to rotate, and then driving the disc 17 to rotate so that the extrusion groove 18 squeezes the guide column 23 to drive the moving block 21 to slide in the guide groove 19, thereby pulling the clamping frame 22 to move outward, and then fixing the pressure cover 33. In the process of rotating the turning handle 28, the turning handle 28 rotates, which will cause the arc-shaped groove 30 to squeeze the elastic ball 32 to deform, thereby causing the elastic ball 32 to move out of the current arc-shaped groove 30 and then move to another adjacent arc-shaped groove 30. The elastic ball 32 is located in the arc-shaped groove 30 and can fix the current position of the turning handle 28. Then the threaded rod 10 is rotated, and under the action of the thread, the slider 12 is moved in the slide groove 9 The cutter head 11 moves inward, thereby driving the cutter head 11 to move, thereby changing the distance between the cutter head 11 and the center of the turntable 15, so that the cutter head 11 can contact the pressure cover 33, starting the motor 13 and the electric push rod 6, the motor 13 drives the turntable 15 to rotate, thereby driving the pressure cover 33 to rotate, and the extension of the electric push rod 6 will cause the mounting plate 8 and the cutter head 11 to move downward synchronously, thereby chamfering the rotating pressure cover 33. In the process of chamfering the pressure cover 33, the rotating turntable 15 will generate centrifugal force, thereby causing the elastic rubber block 27 to extend and deform outward, thereby causing the arc-shaped strip 26 to squeeze the outer gear ring 24, increasing the friction between the outer gear ring 24 and the arc-shaped strip 26, and assisting in fixing the disc 17, so that the clamping of the clamping frame 22 is more stable. Since the cutter head 11 is in a relatively static state, the chamfering accuracy of the equipment is more accurate, and the qualified rate of the pressure cover 33 is improved.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
