One end of 610 passes through the movable groove 762 and is installed with a fixed disk 7611. The outer side of the fixed disk 7611 is bonded with a rubber pad 7612. The fixed seat 766 is arranged at the upper end of the fixed shell 761. The lower end of the fixed seat 766 is provided with a groove. A spring 769 is installed at the top of the inner cavity of the groove. The lower end of the spring 769 is connected to the telescopic part of the telescopic rod 764.

The lower end of the fixed seat 766 is symmetrically connected with positioning columns 768 movably connected thereto. The screw rod 72 is driven to rotate by the servo motor 71, and the threaded block 73 on the outer side of the screw rod 72 is limited and moved in the limiting groove 11 by the limiting block 75 at the lower end of the connecting rod 74, so that the threaded block 73 is moved in the screw rod The outer side of the rod 72 moves left and right, and the limiting groove 11 is a through groove, which is convenient for the debris generated during deburring to fall directly, avoiding accumulation in the limiting groove 11, which increases the difficulty of cleaning and effectively improves practicality. The threaded block 73 drives the entire deburring assembly 76 to move left and right, and limits the leftward movement of the threaded block 73 through the limiting plate 77. The surface threaded block 73 drives the burr assembly 76 to touch the clamping assembly 8, causing damage to parts, and the steel brush 767 of the deburring assembly 76 deburrs and grinds the screw clamped by the clamping assembly 8, and according to the diameter of the screw, the bolt 7610 moves up and down in the moving groove 762 while driving the fixed sleeve 765 to move synchronously, and the fixed sleeve 765 drives the telescopic part of the telescopic rod 764 to move up and down.Then, the telescopic member of the telescopic rod 764 drives the spring 769, the fixing seat 766 and the steel brush 767 to move up and down synchronously, so that the distance between the steel brush 767 and the screw can be adjusted conveniently, and it is convenient to be used for deburring processing of screws of different thicknesses, which effectively improves the use effect.

The side is convenient for effectively fixing the positions of the fixing seat 766 and the steel brush 767, and for flexible adjustment according to the use needs. When the screw and the steel brush 767 are in hard rigid contact, the steel brush 767 drives the fixing seat 766 to compress the spring 769 downward, and drives the positioning column 768 to move up and down in the inner cavity of the positioning groove 763, so that the steel brush 767 can move up and down stably, and the steel brush 767 can float elastically, thereby effectively avoiding the rigid contact between the steel brush 767 and the screw and causing irreparable damage.

[0025] One end of the deburring mechanism 7 passes through the first vertical plate 2 and extends to the right side thereof. The outer side of the first vertical plate 2 is movably connected to the clamping assembly 8. The deburring mechanism 7 and the clamping assembly 8 are meshed and connected. The clamping assembly 8 includes a three-jaw chuck 81, a support seat 82, a support shaft 83, a bearing 84 and a second gear 85. The second gear 85 is meshed with the first gear 78. The gear diameter ratio of the first gear 78 to the second gear 85 is 3:1. The inner cavity of the second gear 85 is installed with a support shaft 83. The support shaft 83 passes through the second vertical plate 3 and is connected to the support seat 82. A three-jaw chuck 81 is installed on one side of the support seat 82. A bearing 84 is installed at the penetration point of the support shaft 83 and the second vertical plate 3. The support shaft 83 is sleeved with the bearing 84. The screw is clamped by the three-jaw chuck 81. When the servo motor 71 drives the screw rod 72 to rotate, the first gear 78 on the outside of the screw rod 72 drives the second gear 85 to rotate, and the second gear 85 drives the support shaft 83, the support seat 82 and the three-jaw chuck 81 to rotate the screw. Since the gear diameter ratio of the first gear 78 and the second gear 85 is 3:1, the support shaft 83 drives the support seat 82 and the three-jaw chuck 81 to rotate at a speed three times that of the screw. Therefore, the movement speed of the threaded block 73 on the outside of the screw rod 72 is relatively low, so that after the screw rod rotates several circles, the threaded block 73 drives the burr assembly 76 to move a shorter distance, which is convenient for comprehensive grinding of the outer surface of the screw rod here, and convenient for one-time grinding, without reciprocating movement several times for multiple grinding, effectively improving work efficiency.

[0026] The upper end of the table top 1 is connected to the second vertical plate 3, and a glass door 6 is movably installed between the second vertical plate 3 and the first vertical plate 2. A baffle 9 is screwed between the second vertical plate 3 and the first vertical plate 2, and a transparent cover 10 is rotatably connected to the upper end of the baffle 9. The glass door 6, the baffle 9 and the transparent cover 10 are used to block the debris generated during deburring to avoid splashing and causing safety hazards. The glass door 6 and the transparent cover 10 can be opened and closed, which is convenient for the screw to be taken out of the clamping machine and convenient for observing the deburring work, thereby improving practicality.

[0027] Working principle: The utility model is connected to the servo motor 71 through the control switch 5. When in use, the glass door 6 and the transparent cover 10 are opened to insert the screw into the three-jaw chuck 81 and clamp it. The three-jaw chuck 81 is an existing product for clamping and fixing workpieces. Its working principle is not repeated here. According to the diameter of the screw, the bolt 7610 moves up and down in the moving groove 762, while driving the fixed sleeve 765 to move synchronously, and the fixed sleeve 765 drives the telescopic part of the telescopic rod 764 to move up and down, and then the telescopic part of the telescopic rod 764 drives the spring 769, the fixed seat 766 and the steel brush 767 to move up and down synchronously, so that the distance between the steel brush 767 and the screw can be adjusted conveniently, so that it is suitable for a variety of screws of different thicknesses. The use of the rod deburring processing effectively improves the use effect, and by tightening the bolt 7610, the bolt 7610 drives the fixed plate 7611 and the rubber pad 7612 toward the fixed shell 761, which makes it convenient for the fixed plate 7611 to drive the rubber pad 7612 to press tightly against the outer side of the fixed shell 761, so as to effectively fix the position of the fixed seat 766 and the steel brush 767, and to facilitate flexible adjustment according to the needs of use. When the adjustment is completed, the servo motor 71 drives the screw rod 72 to rotate, and the threaded block 73 on the outer side of the screw rod 72 drives the entire deburring assembly 76 to move left and right, and the threaded block 73 is limited to move to the left by the limit plate 77. The surface threaded block 73 drives the burr assembly 76 to touch the clamping assembly 8, causing damage to the parts. , and the steel brush 767 of the deburring assembly 76 deburrs and grinds the screw clamped by the clamping assembly 8, and when the screw and the steel brush 767 are in hard rigid contact, the steel brush 767 drives the fixing seat 766 to compress the spring 769 downward, and drives the positioning column 768 to move up and down in the inner cavity of the positioning groove 763, so that the steel brush 767 can move up and down stably, and the steel brush 767 can float elastically, thereby effectively avoiding the rigid contact with the screw and causing irreparable damage. At the same time, the first gear 78 on the outside of the screw 72 drives the second gear 85 to rotate, and the second gear 85 drives the support shaft 83, the support seat 82 and the screw clamped by the three-jaw chuck 81 to rotate, and since the gear diameter ratio of the first gear 78 to the second gear 85 is 3 :1, and then the support shaft 83 drives the support seat 82 and the three-jaw chuck 81 to rotate at a speed three times that of the screw. Therefore, the threaded block 73 on the outside of the screw 72 moves at a lower speed, so that after the screw rotates a few times, the threaded block 73 drives the burr assembly 76 to move a shorter distance, which is convenient for comprehensive grinding of the outer surface of the screw here, and convenient for one-time grinding, without reciprocating several times for multiple grinding, effectively improving work efficiency, and the glass door 6, baffle 9 and transparent cover 10 are used to block the debris generated during deburring to avoid safety hazards caused by splashing everywhere, and the glass door 6 and the transparent cover 10 can be opened and closed, which is convenient for the screw to be taken out of the clamping machine, and convenient for observing the deburring work, thereby improving practicality.
