DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-4 A polishing rod processing positioning mechanism shown in the figure includes a base 1, a plurality of mobile clamps 2 are symmetrically arranged on the top center of the base 1, a mobile component for adjusting the position of the mobile clamp 2 is arranged at the bottom of the mobile clamp 2, a positioning clamp 3 for clamping the polishing rod is arranged on one side of the mobile clamp 2, a connecting component for replacing the positioning clamp 3 is arranged at the connection between the mobile clamp 2 and the positioning clamp 3, the connecting component includes a trapezoidal block 5 fixedly connected to one side of the positioning clamp 3, a trapezoidal groove 4 is opened on one side of the mobile clamp 2, the trapezoidal block 5 is inserted and connected inside the trapezoidal groove 4, and a clamping piece for fixing the position of the trapezoidal block 5 is arranged inside the trapezoidal groove 4.

[0021] It should be noted that the movable clamp 2 is driven by the movable part to move the positioning clamp 3 on one side. When the position of the polishing rod needs to be fixed, the two positioning clamps 3 are driven to move to the opposite side by the movable clamp 2, and the polishing rod is clamped and fixed by the two positioning clamps 3; one side of the positioning clamp 3 is provided with a groove compatible with the polishing rod. When different polishing rods need to be fixed, their positions are fixed by grooves of different sizes on one side; the trapezoidal groove 4 and trapezoidal block 5 are used to limit the moving direction of the trapezoidal block 5. When the trapezoidal block 5 penetrates into the interior of the trapezoidal groove 4, it is limited by the hypotenuse of the trapezoid so that the moving direction of the trapezoidal block 5 is only perpendicular to the base 1, and the clamping part is used to limit the trapezoidal block 5 from moving in the vertical direction, thereby fixing the position of the trapezoidal block 5, and fixing the position of the positioning clamp 3 by the fixed position of the trapezoidal block 5.

[0022] Specifically, the clamping member includes a clamping slot 6 provided on one side of the trapezoidal block 5 , and a clamping block 7 is clamped inside the clamping slot 6 .

[0023] Specifically, a receiving groove 8 is opened on the inner wall of one side of the trapezoidal groove 4, and the clamping block 7 is inserted and connected inside the receiving groove 8. An elastic block 9 is fixedly connected to one side of the clamping block 7, and the elastic block 9 is fixedly connected to the inner wall of one side of the receiving groove 8.

[0024] It should be noted that the elastic block 9 is made of rubber material and is ring-shaped. The rubber material has a deformable property. When in use, when the card block 7 moves to one side of the elastic block 9, the elastic block 9 is deformed due to the extrusion of the card block 7. When the elastic block 9 loses the extrusion of the card block 7, it recovers and pushes the card block 7 to one side of the card slot 6.

[0025] Specifically, a connecting rod 10 is fixedly connected to one side of the block 7, the connecting rod 10 is inserted and connected to the middle part of the elastic block 9, the connecting rod 10 is inserted and connected to the inner wall of one side of the storage groove 8, and the end of the connecting rod 10 away from the block 7 is fixedly connected to a moving cap 11 for moving the position of the block 7.

[0026] It should be noted that the movable cap 11 is arranged on one side of the movable clamp 2, and the movable cap 11 is connected to the clamping block 7 through the connecting rod 10, so that the clamping block 7 located inside the trapezoidal groove 4 can be moved by the movable cap 11 arranged on one side of the movable clamp 2.

[0027] Specifically, a cavity 12 is opened in the middle of the base 1, and the moving component includes a moving block 14 fixedly connected to the bottom end of the moving clamp 2. A moving groove 15 is opened on the inner wall at the top of the cavity 12. The moving block 14 is inserted and connected inside the moving groove 15. The bottom end of the moving block 14 is fixedly connected with a sliding block 13, and the sliding block 13 is inserted and connected inside the cavity 12.

[0028] It should be noted that the movable block 14 is used to connect the sliding block 13 located inside the cavity 12 and the movable clamp 2 located on the top of the base 1; the length of the movable groove 15 is consistent with the length of the cavity 12; the length of the sliding block 13 is greater than the length of the moving block 14, and the moving groove 15 is adapted to the moving block 14, so that the sliding block 13 cannot pass through the cavity 12 through the moving groove 15, thereby fixing the position of the sliding block 13.

[0029] Specifically, a bidirectional screw 16 is inserted and connected to the middle thread of the sliding block 13, one end of the bidirectional screw 16 is inserted and connected to the inner wall of one side of the cavity 12, and the other end of the bidirectional screw 16 is sleeved with a bearing 17, and the bearing 17 is inserted and connected to the inner wall of the other side of the cavity 12.

[0030] It should be noted that a motor for driving the bidirectional screw 16 to rotate is provided on one side of the base 1. When the bidirectional screw 16 needs to be rotated, it is driven to rotate by the motor. The inner groove ring of the bearing 17 is fixedly sleeved on the other end of the bidirectional screw 16, and its outer groove ring is fixedly inserted and connected to the inner wall on the other side of the cavity 12, so that the two ends of the bidirectional screw 16 are fixed by the bearing 17 and the motor respectively.

[0031] Specifically, a guide rod 18 is fixedly connected between the inner walls on both sides of the cavity 12 , and the guide rod 18 is inserted and connected to the middle part of the sliding block 13 .

[0032] It should be noted that the bidirectional screw 16 and the guide rod 18 are respectively inserted and connected on both sides of the middle of the sliding block 13, and the sliding block 13 is restricted by two fixed position rods so that it cannot rotate in the cavity 12. The threads on the bidirectional screw 16 are symmetrically arranged from the middle. When the bidirectional screw 16 needs to be rotated, the two sliding blocks 13 that are threadedly connected to it and cannot rotate are driven to move in different directions, thereby driving the two moving clamps 2 and the positioning clamps 3 to move through the sliding block 13 to complete the clamping, fixing and releasing of the polishing rod.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
