Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and specifically to an aluminum brass cutting device with an automatic positioning function. Background Art

[0002] Aluminum brass profiles are products made of aluminum and brass elements. Usually, they are first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then processed through processes such as cold bending, sawing, drilling, assembling, and coloring; and in the subsequent manufacturing process of aluminum brass profiles, they also need to be cut, welded, etc. to complete the processing.

[0003] When cutting aluminum brass raw materials, affected by the error of manual line drawing, it is often necessary to repeatedly cut and trim the opening, which not only affects the cutting efficiency of aluminum brass raw materials, but also affects the flatness of the cutting end face of aluminum brass raw materials. Summary of the Invention

[0004] The purpose of the present invention is to provide an aluminum brass cutting device with an automatic positioning function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An aluminum brass cutting device with an automatic positioning function includes a support frame, a cutting assembly is arranged on the support frame, two moving assemblies are symmetrically arranged at both ends of the cutting assembly, a fixing group is arranged on one side of one of the moving assemblies away from the cutting assembly, and an auxiliary frame is arranged on the side of the cutting assembly away from the fixing group.

[0007] Preferably, the cutting assembly includes two fixing rings, a debris chamber is arranged between the two fixing rings, a moving groove is arranged at the top of the fixing ring, a moving block is arranged in the moving groove, and a cutting knife is arranged between the two moving blocks.

[0008] The position of the aluminum brass round material to be cut is moved between the two fixing rings. The controller controls the second motor to start, the second motor drives the cutting knife to rotate, and then the controller controls the first motor to rotate, so that the first motor drives the gear to engage with the rack in the moving groove, so that the moving block moves along the moving groove under the action of the gear and rack, so that the moving block drives the cutting knife to move towards the side close to the debris chamber. At this time, the aluminum brass round material rotates under the action of the abutting claws, that is, when the edge of the cutting knife exceeds the axis of the aluminum brass round material, the cutting process can be completed.

[0009] Before cutting, an extrusion bar is arranged between the grinding plate and the aluminum brass round bar, so that the extrusion bar limits the grinding plate. At this time, the grinding plate does not contact the surface of the aluminum brass round bar. During the movement of the cutting tool, the moving block also drives the extrusion bar to move. When the extrusion bar moves, it contacts the grinding plate. Subsequently, under the continuous movement of the moving block, the moving block drives the extrusion bar to continuously extrude the grinding plate, causing the grinding plate to move away from the aluminum brass round bar;

[0010] After the aluminum brass round bar is cut, during the process of the moving block driving the cutting tool to reset, when the moving block resets, the controller continues to control the moving block to move away from the debris chamber. During this process, the moving block continues to drive the extrusion bar to move. When the extrusion bar moves, it disengages from the grinding plate. At this time, the grinding plate loses the extrusion effect of the extrusion bar, causing the grinding plate to contact the side wall of the aluminum brass round bar under the action of the spring. When the aluminum brass round bar rotates, the grinding plate grinds the burrs on the cutting side of the aluminum brass round bar clean.

[0011] Preferably, the moving assembly includes a rotating ring, the rotating ring is rotatably connected to the fixed ring, a moving ring is arranged on the side of the rotating ring away from the fixed ring, several hinge frames are arranged on the outer walls of the moving ring and the rotating ring, a hinge rod is arranged between the moving ring and the rotating ring, and the hinge rod is connected to the hinge frame.

[0012] The aluminum brass round bar passes through the rotating ring and the moving ring in sequence. When the aluminum brass round bar needs to be moved, the moving ring slides along the axis of the moving ring. When the moving ring moves towards the side close to the rotating ring, the hinge frame on the moving ring drives the hinge rod to bend. When the moving ring moves away from the rotating ring, the hinge frame on the moving ring drives the hinge rod to straighten.

[0013] Preferably, the fixing group includes a track, a moving frame is arranged on the track, the moving frame is slidably connected to the track, a claw is arranged on the side of the moving frame close to the cutting assembly, and the claw is rotatably connected to the moving frame.

[0014] The driving motor drives the moving frame to move along the track, and the moving frame drives the claw to move towards the side close to the cutting assembly. According to the length to be cut, the distance between the moving frame and the cutting assembly is controlled, so as to achieve the positioning effect. And through the support of the claw, the other end of the aluminum brass round bar is lifted to prevent one end of the aluminum brass round bar from dropping, resulting in deviation of the cutting length.

[0015] Preferably, two grinding plates are symmetrically arranged in the debris chamber. A spring is arranged between the grinding plate and the debris chamber. A miscellaneous storage chamber is arranged at the bottom of the debris chamber. A plurality of air inlets are arranged in the side wall of the debris chamber. An extrusion strip is arranged between the cutting knife and the moving block. The extrusion strip extends towards the side close to the debris chamber. The extrusion strip is connected to the moving block. The extrusion strip is slidably connected to the cutting knife.

[0016] When the cutting knife cuts the aluminum brass round bar, the cut debris moves along the tangent direction of the cutting knife. By arranging the debris chamber, the generated debris during cutting will not be conveyed outwards, thus avoiding debris splashing. The cut debris is conveyed to the miscellaneous storage chamber through the side of the debris chamber and stored in the miscellaneous storage chamber. When the cutting knife cuts, the rotation of the cutting knife and the flying out of the debris will drive the gas flow in the debris chamber. Then, a part of the gas will flow into the debris chamber through a plurality of air inlets, thus playing a certain role in cooling the cutting knife.

[0017] Preferably, a plurality of cams are arranged in the moving ring. A micro motor is arranged in the moving ring. The driving shaft of the micro motor is connected to the cam. The cam is rotatably connected to the moving ring.

[0018] When the moving ring needs to move the aluminum brass round bar, the micro motor drives the cam to rotate, so that the cam rotates towards the side close to the aluminum brass round bar. Then, a plurality of cams squeeze and clamp the aluminum brass round bar. Then, through the displacement of the moving ring, the aluminum brass round bar is driven to move along the axis of the moving component.

[0019] Preferably, a first motor is arranged in the moving block. A gear is arranged on the driving shaft of the first motor. A rack is arranged on the side wall of the moving groove. The gear meshes with the rack. A second motor is arranged on the side of the moving block close to the cutting knife. The driving shaft of the second motor is connected to the cutting knife.

[0020] Preferably, a driving motor is arranged on the moving frame. The driving motor is used to drive the moving frame to move along the track. A third motor is arranged on the moving frame. The driving shaft of the third motor is connected to the abutting claw.

[0021] After the abutting claw abuts and fixes one end of the aluminum brass round bar, the controller controls the third motor to start. The driving shaft of the third motor drives the abutting claw to rotate, so that the abutting claw drives the whole aluminum brass round bar to rotate, and the aluminum brass round bar is cut by the cutting knife when rotating. At the same time, after cutting is completed, the aluminum brass round bar contacts the grinding plate during self-rotation, thus realizing the deburring treatment of the cut side.

[0022] Preferably, an auxiliary wheel is arranged on the side of the auxiliary frame away from the cutting assembly.

[0023] By setting the auxiliary wheel, when cutting a long aluminum brass round material, it is possible to prevent one end of the aluminum brass round material from falling down, resulting in an uneven cutting surface, and to prevent a certain impact when rotating the aluminum brass round material, resulting in failure to perform normal cutting.

[0024] Preferably, the side of the pawl away from the movable frame is provided with stepped teeth.

[0025] By setting the stepped teeth, the effect of interference fixation can be achieved when contacting aluminum brass round materials of different diameters. By changing the inner wall diameters of the cutting component and the moving component, the cutting process of aluminum brass round materials of different diameters can be completed.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Through the cooperation of the claws, auxiliary frame and moving components, the axis of the aluminum brass round material is aligned with the axis of the claws, moving components and cutting components, thereby ensuring the quality of the aluminum brass raw material during cutting, avoiding displacement of one end of the aluminum brass raw material, resulting in offset of the cutting position, and thus improving the cutting accuracy.

[0028] 2. The driving shaft drives the claw to rotate, so that the claw drives the entire aluminum brass round material to rotate, so that the aluminum brass round material is cut by the cutting knife while rotating. At the same time, after the cutting is completed, the aluminum brass round material contacts the grinding plate during its self-rotation, thereby achieving grinding treatment of the side burrs after the cutting is completed.

[0029] 3. When the cutting knife is cutting, the rotation of the cutting knife and the flying of debris will drive the gas flow in the debris chamber, and then part of the gas will flow into the debris chamber through several air inlets, thereby having a certain cooling effect on the cutting knife.

[0050] As a specific embodiment of the present invention, a plurality of cams 35 are provided in the moving ring 32. A micro motor is provided in the moving ring 32. The driving shaft of the micro motor is connected to the cam 35. The cam 35 is rotatably connected to the moving ring 32.

[0051] The working principle of the present invention:

[0052] The aluminum brass round bar passes through the rotating ring 31 and the moving ring 32 in sequence. When the aluminum brass round bar needs to be moved, the moving ring 32 slides along the axis of the moving ring 32. When the moving ring 32 moves towards the side close to the rotating ring 31, the hinge frame 33 on the moving ring 32 drives the hinge rod 34 to bend. When the moving ring 32 moves towards the side away from the rotating ring 31, the hinge frame 33 on the moving ring 32 drives the hinge rod 34 to straighten;

[0053] The driving motor drives the moving frame 14 to move along the track 13. The moving frame 14 then drives the claw 15 to move towards the side close to the cutting assembly 2, controlling the distance between the moving frame 14 and the cutting assembly 2 according to the length to be cut, so as to achieve the positioning effect. And through the support of the claw 15, the other end of the aluminum brass round bar is lifted to prevent one end of the aluminum brass round bar from dropping, which may cause deviation in the cutting length.

[0054] The position of the aluminum brass round bar to be cut is moved between the two fixed rings 21. The controller controls the second motor to start, and the second motor drives the cutting knife 25 to rotate. Subsequently, the controller controls the first motor to rotate, so that the first motor drives the gear to mesh with the rack in the moving groove 23, causing the moving block 24 to move along the moving groove 23 under the action of the gear and rack, and the moving block 24 drives the cutting knife 25 to move towards the side close to the debris chamber 22. At this time, the aluminum brass round bar rotates under the action of the claw 15, that is, when the edge of the cutting knife 25 exceeds the axis of the aluminum brass round bar, the cutting process is completed.

[0055] When no cutting process is carried out, there is an extrusion strip 29 between the grinding plate 26 and the aluminum brass round bar, so that the extrusion strip 29 limits the grinding plate 26. At this time, the grinding plate 26 does not contact the surface of the aluminum brass round bar. During the movement of the cutting knife 25, the moving block 24 also drives the extrusion strip 29 to move. When the extrusion strip 29 moves, it contacts the grinding plate 26. Subsequently, under the continuous movement of the moving block 24, the moving block 24 drives the extrusion strip 29 to continuously squeeze the grinding plate 26, causing the grinding plate 26 to move away from the aluminum brass round bar.

[0056] After the aluminum brass round bar is cut, when the moving block 24 drives the cutting knife 25 to reset, after the moving block 24 resets, the controller continues to control the moving block 24 to move away from the debris chamber 22. During this process, the moving block 24 continues to drive the extrusion strip 29 to move. When the extrusion strip 29 moves, it disengages from the grinding plate 26. At this time, the grinding plate 26 loses the extrusion effect of the extrusion strip 29, causing the grinding plate 26 to contact the side wall of the aluminum brass round bar under the action of the spring. When the aluminum brass round bar rotates, the grinding plate 26 grinds the burrs on the cutting side of the aluminum brass round bar clean.

[0057] When the cutting tool 25 cuts the aluminum brass round material, the cut debris moves along the tangent direction of the cutting tool 25. By providing a debris chamber 22, the cut debris is not transported outwards, thus avoiding debris splashing. The cut debris is transported to the impurity storage chamber 27 through the side of the debris chamber 22 and stored therein. When the cutting tool 25 cuts, the rotation of the cutting tool 25 and the flying out of the debris will drive the gas flow in the debris chamber 22. Then, a part of the gas will flow into the debris chamber 22 through a plurality of air inlets 28, thereby achieving a certain cooling effect on the cutting tool 25;

[0058] After the abutting claw 15 abuts and fixes one end of the aluminum brass round material, the controller controls the third motor to start. The drive shaft of the third motor drives the abutting claw 15 to rotate, so that the abutting claw 15 drives the entire aluminum brass round material to rotate, and the aluminum brass round material is cut by the cutting tool 25 during rotation. At the same time, after cutting is completed, the aluminum brass round material contacts the grinding plate 26 during self-rotation, thereby realizing the grinding treatment of the burrs on the cut side.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
