Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to an intelligent grinder for producing metal parts. Background Art

[0002] Metal processing and grinding is a common process in the manufacturing process of metal products. Its main purpose is to remove burrs, oxide layers, rust and other uneven parts on the surface of metal products to improve the smoothness and aesthetics of the metal surface.

[0003] When metal parts are produced, there is a welding operation to weld the edges of two metal plates together. At this time, the two metal plates will be fused into a bent metal part. When surface grinding is performed on such irregularly shaped metal parts, in order to pursue efficiency and effect, a soft grinding tool such as a grinding belt with deformation ability will be used to comprehensively grind the metal parts. The specific operation is to control the metal parts to extrude the grinding belt so that the grinding belt is squeezed and deformed to fit the surface of the metal plate to be polished, thereby performing the grinding work. However, during grinding, there are three actual stress points on the grinding belt during the grinding process, namely the contact point of the two power rollers and the point between the two power rollers that is supported by the corner of the metal part. Therefore, the belt surface between the point where the grinding belt is supported by the corner of the metal part and the contact point of the power roller will have uneven contact with the surface of the metal part, which will lead to poor grinding effect. Utility Model Content

[0004] In order to overcome the disadvantage that the belt surface between the point where the grinding belt is supported by the corner of the metal part and the contact point of the power roller is unevenly in contact with the surface of the metal part, thereby resulting in a poor grinding effect, the utility model provides an intelligent grinding machine for metal parts production.

DETAILED DESCRIPTION

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] Example 1

[0021] An intelligent grinding machine for metal parts production, such as Figure 1-Figure 4 As shown, it includes a fixed frame 1, a transmission roller 2, an electric push rod 3, a connecting frame 4, a rotating roller 5, a motor 6 and a grinding belt 7; the fixed frame 1 is rotatably connected to four transmission rollers 2; an electric push rod 3 is fixedly connected to the fixed frame 1; a connecting frame 4 is fixedly connected to the telescopic part of the electric push rod 3; the connecting frame 4 is rotatably connected to a rotating roller 5; the other side of the connecting frame 4 away from the rotating roller 5 is fixedly connected to the motor 6; the output shaft of the motor 6 is fixedly connected to the rotating roller 5; all the transmission rollers 2 and the rotating roller 5 are covered with a grinding belt 7;

[0022] It also includes a connecting plate 8, a rotating plate 9, a sliding mounting frame 10, a rotating rod 11 and a compression spring 101; the fixed frame 1 is fixedly connected to two connecting plates 8, and the connecting plates 8 are located within the surrounding range of the grinding belt 7; the two connecting plates 8 are distributed at right angles; each connecting plate 8 is connected to a rotating plate 9; each rotating plate 9 is slidably connected to a plurality of sliding mounting frames 10; each sliding mounting frame 10 is rotatably connected to a rotating rod 11; each sliding mounting frame 10 is fixedly connected to four compression springs 101 together with the rotating plate 9.

[0023] The surface of the rotating rod 11 is rough, so that the grinding belt 7 can drive the rotating rod 11 to rotate, and the grinding belt 7 can be prevented from rubbing against the rotating rod 11, thereby affecting the service life of the grinding belt 7 and the rotating rod 11.

[0024] It also includes a torsion spring 111; the connecting plate 8 is rotatably connected to the rotating plate 9; each connecting plate 8 and the corresponding rotating plate 9 are fixedly connected to a torsion spring 111.

[0025] It also includes an electric push rod 112 and a clamping block 113; each connecting plate 8 is fixedly connected to an electric push rod 112 on its upper side; each electric push rod 112 has a clamping block 113 fixedly connected to its telescopic portion for clamping the rotating plate 9 so that it cannot rotate.

[0026] Each rotating plate 9 is provided with a plurality of grooves 9001 , and the surface of the clamping block 113 is provided with protrusions that cooperate with the grooves 9001 , thereby increasing the friction force, so that the clamping block 113 can better clamp the rotating plate 9 and prevent the rotating plate 9 from rotating.

[0027] The transmission roller 2 is provided with a limiting portion 2001, and the limiting portion 2001 prevents the grinding belt 7 from moving up and down and separating from the transmission roller 2 when moving.

[0028] The specific working steps are:

[0029] Before the grinding work is carried out, the fixing frame 1 is fixed on the workbench, and then the metal part 100 to be ground is fixed by an external feeding device, such as a mechanical claw with a suction cup, and then the external feeding device pushes the metal part 100, so that the area of ​​the metal part 100 to be ground squeezes the grinding belt 7, so that the grinding belt 7 is tightly attached to the area to be ground of the metal part 100, and while the metal part 100 is squeezing the grinding belt 7, the electric push rod 3 pushes the connecting frame 4 to drive the rotating roller 5 connected thereto to move outward, and adjusts the tightness of the grinding belt 7. When the difference of the metal part 100 to be ground is completely wrapped by the grinding belt 7, it stops moving. Figure 2 The grinding belt 7 is in the state shown, and then the motor 6 drives the grinding belt 7 to rotate counterclockwise from a top view, and the grinding belt 7 will drive the other rotating rollers 5 to rotate when rotating, and at this time the grinding belt 7 will grind the metal part 100, thereby realizing the grinding of the metal part 100, and the metal part 100 will indirectly squeeze the expanded rotating rod 11 and the sliding mounting frame 10 when squeezing the grinding belt 7, so that the rotating rod 11 moves through the sliding mounting frame 10 to squeeze the compression spring 101, so that it is in a compressed state, and the compressed compression spring 101 will provide a reverse extrusion force, at this time the compression spring 101 drives the rotating rod 11 through the sliding mounting frame 10 to reversely squeeze the grinding belt 7, and at this time the rotating rod 11 will squeeze the grinding belt 7 so that the rotating roller 5 on the grinding belt 7 fits with the surface of the metal part 100, thereby avoiding insufficient contact between the surface of the metal part 100 and the grinding belt 7, which leads to a poor grinding effect.

[0030] The connecting frame 4 slides the mounting frame 10, slides the mounting frame 10, slides the mounting frame 10, and slides the mounting frame 10. Considering that when different metal parts 100 are polished, it is impossible to ensure that the opening and closing angles of each metal part 100 are consistent, when the metal part 100 squeezes the polishing belt 7 and moves the polishing belt 7, the polishing belt 7 will first contact with the rotating rod 11 on one side, and the sliding mounting frame 10. At this time, since the rotating plate 9 is rotatably connected to the connecting plate 8, the rotating rod 11 on one side will be squeezed, and the compression spring 101 The elastic coefficient is greater than the elastic coefficient of the torsion spring 111. The squeezed rotating rod 11 drives the rotating plate 9 through the compression spring 101. At this time, the rotating plate 9 will rotate, causing the torsion spring 111 to be in a twisted state, so that the rotating plate 9 drives all the rotating rods 11 to rotate and fit the grinding belt 7. Then, when grinding the grinding parts of the metal part 100 with different opening and closing angles, the rotating rod 11 can change the inclination angle and has adaptability, thereby ensuring that the sliding mounting frame 10 of the rotating rod 11 applies a stable extrusion force to the grinding belt 7, thereby ensuring its grinding effect.

[0031] In order to prevent the rotating plate 9 in a free state from being in an unstable state due to the friction force generated by the metal part 100 on the rotating rod 11 when the torsion spring 111 is twisted, the electric push rod 112 drives the clamping block 113 to move away from the rotating plate 9 before grinding. When the rotating rod 11 is in close contact with the grinding belt 7, the electric push rod 112 drives the clamping block 113 to move and be in close contact with the rotating plate 9. At this time, the clamping block 113 clamps the rotating plate 9, thereby completely fixing the position of the rotating plate 9 and preventing the rotating plate 9 from rotating itself, which would affect the squeezing effect of the rotating rod 11 on the grinding belt 7.

[0032] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
