[0020] like Figures 1 to 3 As shown, the disk ring screw locking mechanism of the utility model includes: a frame 1, a supporting platform 2 is formed on the top surface of the frame 1, and a turntable 3 is rotatably installed on the supporting platform 2; a centering clamping assembly, the centering clamping assembly is arranged on the turntable 3, and the centering clamping assembly has at least two groups of centering clamping units 4 that can center clamp and fix the disk ring on the turntable 3; a screwing assembly 5, the screwing assembly 5 is arranged on the frame 1 outside the turntable 3, and the screwing assembly 5 at least includes a bracket 51 arranged on the frame 1 and a locking head 52 that can be raised and lowered and rotatably arranged on the bracket 51.

[0021] See also Figure 1 、 Figure 2 The supporting platform 2 is protruding upward on the frame 1, and the turntable 3 is rotatably installed on the supporting platform 2. The frame 1 is provided with a driving source for driving the turntable 3 to rotate, and the driving source can be a rotary cylinder or a servo motor; the centering clamping assembly arranged on the turntable 3 has at least two groups of centering clamping units 4 arranged along the radial direction of the turntable 3, and at least two groups of centering clamping units 4 are evenly arranged on the turntable 3 to apply uniform pressure to the disk ring placed on the turntable 3, thereby improving the fixing effect of the disk ring.

[0022] See also Figure 1 The screwing assembly 5 at least includes a bracket 51 configured on the frame 1 and a locking head 52 rotatably mounted on the bracket 51. The locking head 52 can be vertically raised and lowered on the bracket 51, and the locking head 52 can be adapted to the screws locked on the disc ring. In addition, the frame 1 can also be provided with a robot, which uses the robot to place the screws on the disc ring to be installed, thereby improving the degree of automation of the screw locking process of this application.

[0023] Specifically, when locking the screw in the predetermined position of the disc ring, first place the disc ring on the turntable 3, and use the centering clamping unit 4 to clamp and fix the disc ring. Thereafter, use a robot or manual to place the screw at the position of the disc ring where the screw is to be locked, and then control the locking head 52 to move down to hold the screw, and control the locking head 52 to rotate to screw the screw onto the disc ring. After the screw at one place of the disc ring is locked, the turntable 3 can be driven to rotate to rotate the next part of the disc ring to be screwed to directly below the locking head 52, and then repeat the above operation to complete the locking of the screw. The disc ring is clamped by at least two groups of centering clamping units 4, which can ensure the stability of the disc ring when locking. The rotary cylinder is used to rotate the turntable 3 to control the rotation of the disc ring, which can realize locking the screw at different positions of the disc ring. It has the characteristics of high degree of automation and consistent screw locking degree, and is practical.

[0024] In one or more embodiments, the screwing assembly 5 further includes a first driving device 53 vertically arranged on the bracket 51, a support plate 54 driven to rise and fall by the first driving device 53, and a second driving device 55 arranged on the support plate 54 for driving the locking head 52 to rotate.

[0025] See also Figure 1 The first driving device 53 can be a linear module or a cylinder. The support plate 54 is arranged at the shaft end of the first driving device 53 and is vertically driven to rise and fall by the first driving device 53. The locking head 52 is rotatably arranged on the support plate 54 and extends out from the bottom of the support plate 54. The second driving device 55 is arranged on the top surface of the support plate 54 and is used to drive the locking head 52 to rotate. The second driving device 55 can be a servo motor or a rotary cylinder. There is no specific restriction and it can be selected according to actual production needs.

[0026] When tightening a screw on a disc ring, first, the first drive device 53 is used to control the support plate 54, the second drive device 55, and the locking head 52 to move downward synchronously so that the locking head 52 can hold the screw on the disc ring. Thereafter, the second drive device 55 is used to control the locking head 52 to rotate to lock the screw on the disc ring. After the screw is tightened, the first drive device 53 is used to control the locking head 52 to rise and disengage from the disc ring, making it easier to tighten the screw on the disc ring next time. In addition, it should be noted that a torque sensor can be installed between the second drive device 55 and the locking head 52 to improve the tightening accuracy of the screw.

[0027] In one or more embodiments, the position of the bracket 51 on the frame 1 along the radial direction of the turntable 3 is adjustable.

[0028] It is understandable that when the diameter of the disc ring part to be processed changes, the position of the screw locking on the disc ring part needs to be changed accordingly; in order to ensure that the locking head 52 can smoothly clamp the screw, the bracket 51 needs to be configured to be detachably installed on the frame 1 along the radial direction of the turntable 3. Specifically, the bracket 51 can be installed on the frame 1 using bolts to adjust the position of the bracket 51, or, the cylinder can be used to push the bracket 51 to move along the radial direction of the turntable 3 to approach or move away from the central axis of the turntable 3, so as to change the position of the locking head 52.

[0029] In one or more embodiments, the centering clamping unit 4 includes a pushing structure 41 arranged on the turntable 3 along the radial direction of the turntable 3 and a clamping plate 42 pushed by the pushing structure 41; the clamping plate 42 is provided with a rubber pad on the surface away from the central axis of the turntable 3.

[0030] See also Figure 1 、 Figure 2 The pushing structure 41 includes a driving member and a screw connected to the driving member. The driving member can be a servo motor. The screw is threadedly mounted on the clamping plate 42 at one end away from the driving member. The clamping plate 42 has an arc-shaped curved structure to adapt to the inner wall of the disc ring.

[0031] Specifically, to clamp and secure the disc ring, the disc ring is first placed on the turntable 3 so that the plurality of clamping plates 42 are located within the disc ring. The screw is then rotated by a driver to move the clamping plates 42 radially away from the central axis of the turntable 3, thereby pressing against the inner wall of the disc ring and securing the disc ring. The rubber pads installed on the outer surfaces of the clamping plates 42 reduce damage to the disc ring when the clamping plates 42 are clamping the disc ring, reducing the possibility of scratches on the disc ring surface.

[0032] In one or more embodiments, a sink is opened in the middle of the top surface of the turntable 3, and a circular baffle 6 is detachably connected to the sink; the bottom surface of the circular baffle 6 is provided with an elastic member 7 extending out of the bottom surface of the circular baffle 6.

[0033] See also Figure 1 、 Figure 2 , the annular baffle 6 is relatively located on the outside of the splint 42 in the sink groove; when the disc ring part is placed on the turntable 3, the annular baffle 6 restricts the disc ring part, which can make the disc ring part closer to the splint 42, avoiding a large deviation in the position of the disc ring part placed on the turntable 3, which causes the splint 42 to push the disc ring part to adjust its position on the turntable 3 too much; the configuration of the elastic member 7 can push the annular baffle 6 upward when the annular baffle 6 is removed and replaced for easy removal and placement.

[0034] In one or more embodiments, the bottom surface of the turntable 3 contacts the supporting platform 2 via a rolling element 8 .

[0035] See also Figure 1 The rolling element 8 can be one of a ball, a roller, and a roller; by configuring the rolling element 8 on the outer peripheral side of the bottom surface of the turntable 3 to roll in contact with the supporting platform 2, the stability of the turntable 3 during operation is guaranteed and the problem of deviation of the turntable 3 is reduced.

Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
