DETAILED DESCRIPTION

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0017] like Figure 1 As shown, an automatic deburring device of the present invention comprises a base 1 , a deburring component and a fixing component, wherein the deburring component and the fixing component are both fixed on the base 1 .

[0018] The deburring assembly comprises a moving mechanism, a grinding mechanism and an auxiliary mechanism, wherein the moving mechanism is used to drive the grinding mechanism and the auxiliary mechanism to move forward and backward.

[0019] The moving mechanism includes a slide rail, a screw rod 2, a nut seat 3 and a bracket 4. The slide rail is arranged parallel to the screw rod 2. The bottom of the nut seat 3 is slidably connected to the slide rail. The screw rod 2 is threadedly connected to the nut seat 3. The bracket 4 is fixed to the nut seat 3. The screw rod 2 is driven to rotate by the first motor 5. The body of the first motor 5 is fixed to the base 1. The first motor 5 drives the screw rod 2 to rotate, and the nut seat 3 threadedly connected to the screw rod 2 will move along the screw rod 2. The first motor 5 is a forward and reverse motor, which can realize the nut seat 3 moving forward or backward along the screw rod 2, thereby driving the grinding mechanism and the auxiliary mechanism to move forward or backward.

[0020] The grinding mechanism includes a first cylinder 6, a fixed frame 7, a second motor 8, a grinding disc 9 and a rotating shaft 10. The cylinder body of the first cylinder 6 is fixed to the bracket 4. The extension rod of the first cylinder 6 is relatively fixed to the body of the second motor 8 through the fixed frame 7. The second motor 8 drives the rotating shaft 10 to rotate. The grinding disc 9 is fixed on the rotating shaft 10. The grinding surface of the grinding disc 9 is an arc surface. The grinding surface of the grinding disc 9 faces the fixed component, and the auxiliary mechanism is located in front of the grinding surface. The grinding disc 9 is similar to a bowl shape, and the grinding surface, that is, the surface facing the end of the steel pipe, is an arc surface, which can grind the burrs on the end of the steel pipe and the inner wall near the end. The second motor 8 drives the rotating shaft 10 to rotate, and the grinding disc 9 on the rotating shaft 10 will rotate with the rotating shaft 10. The position of the grinding disc 9 is advanced by the moving mechanism. After the grinding disc 9 is in place, the grinding disc 9 grinds the end of the steel pipe and the inner wall near the end by rotating. The distance that the moving mechanism drives the grinding disc 9 to move forward and backward can be set to a fixed value, so that the grinding disc 9 moves to a fixed position to start grinding, and retreats a fixed distance after grinding is completed, and repeats this operation for the next grinding. In this way, the grinding disc 9 is ground at a fixed position, so the end position of the steel pipe to be ground also needs to be fixed so that it can cooperate with the grinding disc 9 for grinding. A positioning mechanism is provided on the side of the support seat 19 close to the deburring component of the present invention, and the positioning mechanism includes a positioning cylinder 28 and a stopper 29, the cylinder body of the positioning cylinder 28 is fixed to the base 1, the stopper 29 is fixed to the extension rod of the positioning cylinder 28, and the stopper 29 slides against the side of the support seat 19. In order to limit the movement of the stopper 29, the side of the support seat 19 has a vertical guide rail, and the stopper 29 is slidably connected to the guide rail. The stopper 29 is driven to move up and down by the positioning cylinder 28. When the stopper 29 moves up and protrudes out of the support seat 19, the first pad 22, and the second pad 23, the ends of the steel pipe located on the first pad 22 and the second pad 23 can be blocked by the stopper 29 to achieve the positioning of the end position. After the ends of the steel pipe are positioned, the positioning cylinder 28 is driven to contract, so that the stopper 29 moves down to avoid interference with the grinding.

[0021] The auxiliary mechanism includes an auxiliary cylinder 11, an electronic cylinder 12, a fixing ring 13 and at least two groups of auxiliary units. One end of the auxiliary cylinder 11 is connected to the end of the rotating shaft 10 away from the second motor 8 through a bearing 14. The cylinder body of the electronic cylinder 12 is fixed in the auxiliary cylinder 11. The fixing ring 13 is sleeved and fixed on the outer wall of the auxiliary cylinder 11. Each group of auxiliary units includes a roller 15, a connecting rod 16, a torsion spring 17 and a support rod 18. The roller 15 is arranged at one end of the connecting rod 16. The other end of the connecting rod 16 is rotatably connected to the fixing ring 13 through the torsion spring 17. One end of the support rod 18 is rotatably connected to the extension rod of the electronic cylinder 12. A strip hole is opened on the auxiliary cylinder 11. One end of the support rod 18 connected to the electronic cylinder 12 is located in the auxiliary tube 11, and the other end of the support rod 18 passes through the strip hole and is rotatably connected to the middle of the connecting rod 16; in the initial state, the electronic cylinder 12 pulls the support rod 18 to make the connecting rod 16 tilt toward the outer wall of the auxiliary tube 11, and the roller 15 is also close to the outer wall of the auxiliary tube 11, so that the roller 15 can smoothly enter the steel pipe to be deburred. After it is in place, the electronic cylinder 12 releases the support rod 18, so that the connecting rod 16 drives the roller 15 to rotate away from the outer wall of the auxiliary tube 11 around the torsion spring 17 under the restoring force of the torsion spring 17, so that the roller 15 is against the inner wall of the steel pipe to be deburred. The setting of the auxiliary mechanism can ensure the effective support of the grinding mechanism, avoid the eccentric rotation of the grinding mechanism, and cause the grinding position to shift, affecting the grinding effect.

[0022] The fixing assembly includes a support seat 19, a pressure seat 20 and a second cylinder 21. The support seat 19 is located on the base 1. The support seat 19 is provided with a first cushion block 22 and a second cushion block 23, both of which are tilted. The first cushion block 22 is identical to the second cushion block 23 and is symmetrically arranged on the left and right. The pressure seat 20 is provided with a third cushion block 24 and a fourth cushion block 25, both of which are tilted. The third cushion block 24 is identical to the fourth cushion block 25 and is symmetrically arranged on the left and right. The first cushion block 22 and the third cushion block 24 are symmetrically arranged up and down, and the second cushion block 23 and the fourth cushion block 25 are symmetrically arranged up and down, and as shown in FIG. Figure 2 As shown, the symmetry plane s1 is coplanar with the symmetry plane s2, the central axis of the rotating shaft 10 is located on the symmetry plane s1 and the symmetry plane s2, the symmetry plane s3 is coplanar with the symmetry plane s4, the central axis of the rotating shaft 10 is located on the symmetry plane s3 and the symmetry plane s4, the symmetry plane s1 is perpendicular to the symmetry plane s3, the symmetry plane s1 is the symmetry plane of the first cushion block 22 and the second cushion block 23, the symmetry plane s2 is the symmetry plane of the third cushion block 24 and the fourth cushion block 25, the symmetry plane s3 is the symmetry plane of the first cushion block 22 and the third cushion block 24, the symmetry plane s4 is the symmetry plane of the second cushion block 23 and the fourth cushion block 25, the cylinder body of the second cylinder 21 is fixed to the base 1 through the connecting frame 26, and the extending rod of the second cylinder body is fixed to the pressure seat 20.

[0023] The initial position of the first cylinder 6 makes the rotating shaft 10 located on the intersection line of the symmetry plane s1 and the symmetry plane s3. In this way, the initial position of the first cylinder 6 is correlated with the initial position of the second cylinder 21, and the subsequent displacement of the first cylinder 6 can be correlated with the displacement of the second cylinder 21, so as to realize automatic alignment with the central axis of the steel pipe to be deburred. The displacement of the first cylinder 6 is half of the displacement of the second cylinder 21, and the displacement direction of the first cylinder 6 is the same as that of the second cylinder 21. The second cylinder 21 drives the pressure seat 20 to move up and down, that is, drives the third cushion block 24 and the fourth cushion block 25 to move up and down, so the symmetry plane s3 and the symmetry plane s4 will actually change their up and down positions. The displacement of the press seat 20, the third pad 24 and the fourth pad 25 driven by the second cylinder 21 is associated with the outer diameter of the steel pipe to be deburred. The third pad 24 and the fourth pad 25 are against the outer wall of the steel pipe to be deburred. Due to the obstruction of the steel pipe, the second cylinder 21 cannot drive the press seat 20 downward. The displacement of the second cylinder 21 from the initial position at this time can be recorded, which can be associated with the outer diameter of the steel pipe to be deburred. Correspondingly, the first cylinder 6 moves half of the displacement of the second cylinder 21, which can correspond to the central axis position of the steel pipe to be deburred. Since the displacement of the second cylinder 21 from the initial position is actually twice the radius difference between the radius of the initial position and the radius of the steel pipe to be deburred, the first cylinder 6 only needs to move half of the displacement of the second cylinder 21 to correspond to the central axis of the steel pipe to be deburred from the initial position. The initial position radius refers to the radius of the largest round tube that the first cushion block 22, the second cushion block 23, the third cushion block 24 and the fourth cushion block 25 can abut against in the initial position.

[0024] The first cylinder 6 and the second cylinder 21 are both arranged vertically to achieve the movement of the rotating shaft 10 and the pressing seat 20 up and down.

[0025] An electric control box 27 is provided on the base 1, and a PLC is provided in the electric control box 27. The first motor 5, the second motor 8, the first cylinder 6 and the second cylinder 21 are all controlled by the PLC, and automatic deburring can be achieved through the PLC control.

[0026] The auxiliary mechanism includes three groups of auxiliary units, and the three groups of auxiliary units are evenly arranged around the auxiliary cylinder 11. The three points can form a stable support, provide a stable support for the other end of the rotating shaft 10, prevent the rotating shaft 10 from rotating eccentrically, and ensure the deburring and grinding effect.

[0027] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
