[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figure 1-Figure 5 The utility model provides a deburring device for mechanical processing, comprising:

[0026] A base 1, a lifting plate 2 is fixedly connected to the base 1, a lifting platform 3 is vertically slidably connected to the lifting plate 2, a lifting driving member is arranged between the lifting platform 3 and the lifting plate 2, and a placing plate 11 is arranged on the top of the base 1;

[0027] The surface grinding assembly includes a first motor 5 vertically fixedly connected to the lifting platform 3, a rotating member is provided between the first motor 5 and the lifting platform 3, a grinding disc 6 is transmission-connected to the rotating member, and the grinding disc 6 is located above the placement plate 11;

[0028] The pipe mouth grinding assembly includes a rotating member arranged between the base 1 and the placement plate 11 and a pipe grinding part arranged in the grinding disc 6, and a clamping piece is arranged on the placement plate 11.

[0029] The main function of the lifting drive is to drive the lifting platform 3 to adjust the height; the main function of the placement plate 11 is to place the workpiece to be processed; the main function of the grinding disc 6 is to grind the surface of the workpiece; the main function of the rotating member is to convert the rotation of the first motor 5 into the rotational motion of the grinding disc 6; the main function of the tube grinding part is to grind the port and the inner side of the port of the tubular workpiece; the main function of the rotating member is to drive the workpiece to rotate by driving the rotation of the placement plate 11, so that the pipe mouth of the workpiece can be polished. On the whole, the utility model can not only grind the flat surface of the workpiece, but also remove burrs from the port and the inner side of the port of the tubular workpiece, which can meet the deburring needs of various workpiece structures and has high burr removal efficiency.

[0030] As a further optimization scheme, a controller 23 is provided on the base 1, and the controller 23 is electrically connected to the lifting drive member, the first motor 5, the rotating member and the pipe grinding part.

[0031] A further optimized solution is that the rotating part includes a rotating bracket 9 fixedly connected to the output shaft of the first motor 5, the rotating bracket 9 is eccentrically arranged with the output shaft of the first motor 5, the bottom of the rotating bracket 9 is coaxially rotatably connected with a gear 13, a through hole is opened on the lifting platform 3, a ring gear 14 is fixedly connected in the through hole, the gear 13 is located on the inner side of the ring gear 14 and meshes with the ring gear 14, and the top of the grinding disc 6 is coaxially fixedly connected with the bottom of the gear 13.

[0032] like Figure 2 and Figure 3As shown, when a workpiece with a flat surface needs to be polished, the workpiece is placed on the placement plate 11. The first motor 5 is controlled to rotate by the controller 23, driving the rotating bracket 9 to rotate eccentrically in the through hole of the lifting platform 3, and the rotating bracket 9 drives the gear 13 to rotate eccentrically synchronously. Due to the meshing action of the gear 13 and the ring gear 14, the gear 13 rotates eccentrically in the through hole and rotates on the rotating bracket 9. Since the grinding disc 6 and the gear 13 are fixedly connected, the grinding disc 6 will move synchronously with the gear 13, that is, it will simultaneously revolve around the axis of the first motor 5 and rotate around its own axis on the upper surface of the workpiece. Combining the two sets of rotation modes can not only ensure that every part of the workpiece can contact the grinding disc 6, but also improve the efficiency of deburring.

[0033] A further optimized solution is that the pipe grinding part includes a second motor 17 arranged in the grinding disk 6 and a groove 15 opened at the bottom of the grinding disk 6, and a grinding roller 16 is coaxially fixedly connected to the output shaft of the second motor 17, and the grinding roller 16 is located in the groove 15, and a position adjustment part is provided between the second motor 17 and the grinding disk 6.

[0034] In a further optimized solution, the bottom of the grinding disc 6 is fixedly connected with an abrasive 7, which is arranged in an annular shape and is located outside the groove 15. The grinding roller 16 and the abrasive 7 can be a burr brush structure or an abrasive grain structure.

[0035] A further optimized solution is that the position adjustment part includes a slider 18 slidably connected to the grinding disc 6, a second motor 17 is fixedly connected to the slider 18, a first screw rod 8 is rotatably connected to the grinding disc 6, the first screw rod 8 is parallel to the sliding direction of the slider 18 and is transmission-connected to the slider 18, and both ends of the first screw rod 8 respectively pass through the grinding disc 6.

[0036] A friction material made of rubber is arranged between the first screw rod 8 and the grinding disc 6. The rotation resistance of the first screw rod 8 is appropriately increased, which can effectively prevent the first screw rod 8 from rotating and ensure the stability of the relative position of the slider 18 in the grinding disc 6.

[0037] A further optimized solution is that the rotating part includes an annular slide rail 25 fixedly connected to the bottom of the placement plate 11, the annular slide rail 25 is slidably connected to the base 1, a third motor 19 is fixedly connected inside the base 1, and the output shaft of the third motor 19 is coaxially arranged with the annular slide rail 25 and fixedly connected to the bottom of the placement plate 11.

[0038] like Figure 2As shown, when it is necessary to remove burrs from the port and the inner side of the port of the pipe-turned workpiece, the workpiece can be fixed on the placement plate 11 by a clamping member, and then the lifting drive member is controlled to make the workpiece located inside the groove 15. Then, the first screw 8 is rotated, and when the first screw 8 rotates, the slider 18 is driven to move along the axis of the first screw 8 through threaded transmission, and the grinding roller 16 is driven to move synchronously until it fits with the inner wall of the pipe-turned workpiece. Then, the second motor 17 and the third motor 19 are controlled to rotate, and the second motor 17 drives the grinding roller 16 to grind and remove burrs on the inner side of the workpiece, and the third motor 19 causes the workpiece to rotate around its own axis, so that the inner side wall of the axis of the workpiece can contact the grinding roller 16, ensuring that the burrs are completely removed.

[0039] A further optimized solution is that the clamping fixture includes a transverse sliding groove 20 opened on the placement plate 11, two groups of clamping blocks 10 are slidably connected in the transverse sliding groove 20, a bidirectional screw rod 24 is rotatably connected in the transverse sliding groove 20, the two groups of clamping blocks 10 are transmission-connected at both ends of the bidirectional screw rod 24, and a screwing piece is provided at one end of the bidirectional screw rod 24.

[0040] like Figure 4 As shown, a bolt head 12 is fixedly connected to one end of the bidirectional screw 24, and the bolt head 12 is exposed on the side wall of the placement plate 11. When it is necessary to clamp a tubular workpiece on the placement plate 11, the bolt head 12 can be rotated by a tool, so that the bolt head 12 drives the bidirectional screw 24 to rotate, and when the bidirectional screw 24 rotates, the two groups of clamping blocks 10 are driven to move toward the middle of the placement plate 11 at the same time to clamp the workpiece. At the same time, since the two groups of clamping blocks 10 are symmetrically arranged at both ends of the bidirectional screw 24, when the clamping blocks 10 clamp the workpiece, it can be ensured that the axis of the tubular workpiece and the axis of the third motor 19 coincide with each other.

[0041] A further optimized solution is that the lifting drive component includes a plurality of vertical slide grooves 4 opened on the lifting plate 2, and a second screw rod 21 is rotatably connected in the plurality of vertical slide grooves 4. The plurality of second screw rods 21 are respectively transmission connected to the lifting platform 3, and one end of the second screw rod 21 is transmission connected to a fourth motor 22, and the fourth motor 22 is fixedly connected in the lifting plate 2.

[0042] like Figure 5 As shown, when the height of the lifting platform 3 needs to be raised, the fourth motor 22 is controlled to rotate by the controller 23, and the fourth motor 22 drives the second screw rod 21 to rotate. When the second screw rod 21 rotates, the lifting platform 3 is driven to increase in height through the bolt transmission. When the height of the lifting platform 3 needs to be lowered, the fourth motor 22 is controlled to reverse.

[0043] The working process of this embodiment is as follows: when a workpiece with a flat surface needs to be polished, the workpiece is placed on the placement plate 11, and it is selected whether to use the clamping block 10 to fix the workpiece. Then, the operation controller 23 controls the fourth motor 22 to rotate, so that the bottom abrasive 7 of the polishing disc 6 contacts the surface of the workpiece, and the operation controller 23 starts the first motor 5 to remove burrs from the workpiece.

[0044] When it is necessary to remove burrs from the inner side of the port of the tubular workpiece, after placing the tubular workpiece on the placement plate 11, the bolt head 12 is rotated by a tool to make the two sets of clamps 10 move closer to the middle and clamp the tubular workpiece. The operation controller 23 controls the fourth motor 22 to rotate, so that the grinding disc 6 descends and the tubular workpiece is located in the groove 15, and the grinding roller 16 is located in the tubular workpiece. The first screw 8 is rotated to make the grinding roller 16 fit the inner wall of the port of the tubular workpiece. After that, the operation controller 23 starts the second motor 17 and the third motor 19 to remove burrs from the inner side of the port of the tubular workpiece.
