Description

Technical Field

[0001] This invention relates to a metal processing machine, and more particularly to a riveting machine. Background Technology

[0002] With the continuous development of technology, products are also constantly being updated. Due to the market environment, products are often launched into the market before the production technology is mature. Inevitably, some defects will occur during the manufacturing process. These defective products are often irreparable due to certain defects, but because of their high value, they cannot be scrapped directly. The products need to be disassembled and the recyclable parts are then removed and reused in production.

[0003] Currently, most riveting work is done manually, which is inefficient and the quality of riveting is unstable, easily leading to product damage. For example, when riveting micro motors, since the assembly process of micro motors is generally riveting, and the riveting points are difficult to disassemble, it is easy to cause the housing and end cover to be scrapped after disassembly. Summary of the Invention

[0004] The purpose of this invention is to provide a riveting machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The solution to the technical problem of this invention is:

[0006] A riveting removal machine includes a worktable, on which are provided: a workpiece positioning seat with a workpiece positioning groove on its top surface; a clamping mechanism having a clamping end that can move up and down, the clamping end being located directly above the workpiece positioning seat; and a riveting removal mechanism including a movable device and a blade, the blade having an arc-shaped cutting edge, the movable device driving the blade to rotate and causing the blade to move in a direction closer to or away from the workpiece positioning seat.

[0007] This technical solution has at least the following beneficial effects: the workpiece to be derived is placed into the workpiece positioning groove, the clamping end of the clamping mechanism moves downward to clamp the workpiece onto the workpiece positioning seat, the moving device drives the blade to rotate, so that the arc-shaped blade abuts against the edge of the rivet, as the blade continues to rotate, the blade lifts the cap on the rivet, the moving device continues to drive the blade to move away from the workpiece positioning seat, destroying the cap of the rivet and completing the derivation. This greatly improves the derivation efficiency and stability, reduces labor, and increases production efficiency.

[0008] As a further improvement to the above technical solution, the movable device includes a support shaft, a slider, a tool holder, a first drive assembly, and a second drive assembly. The slider is slidably connected to the worktable, and the support shaft is rotatably connected to the slider. The axis of rotation of the support shaft extends horizontally. The first drive assembly drives and connects to the support shaft, and can drive the support shaft to rotate. One end of the tool holder is connected to the portion of the support shaft located above the slider. The axis of rotation of the tool holder is parallel to the support shaft. The blade is connected to the end of the tool holder near the support shaft. The second drive assembly drives and connects to the end of the tool holder away from the support shaft, and can drive the tool holder to rotate, causing the slider to slide in a direction away from or near the workpiece positioning seat. When riveting is required, the second drive assembly drives the blade to rotate via the tool holder and pulls the slider away from the workpiece positioning seat. During this process, the first drive assembly drives the support shaft to rotate. Through the combined motion of the support shaft rotation and the tool holder rotation, the blade always contacts the rivet cap and successfully breaks the cap. In this way, the rotation fulcrum of the blade moves with the action of riveting, preventing the blade from disengaging from the rivet point and greatly improving the stability and quality of riveting.

[0009] As a further improvement to the above technical solution, the first driving assembly includes a first telescopic driving member. The first telescopic driving member has a first fixed part and a first telescopic part that moves along a straight line on the first fixed part. The first fixed part is rotatably connected to the worktable. A first clearance opening is provided on the worktable directly opposite the support shaft. The bottom end of the support shaft passes through the first clearance opening and extends into the worktable. A transition block extending in a direction away from the workpiece positioning seat is connected to the bottom end of the support shaft. The first telescopic part is rotatably connected to the transition block. The rotation axis of the first fixed part and the rotation axis of the first telescopic part are both parallel to the rotation axis of the support shaft. During riveting, the first telescopic part extends out of the first fixed part, and the top of the support shaft rotates away from the workpiece positioning seat, pushing the rotation fulcrum of the blade upward, thereby better inserting the blade into the rivet point. Since the support shaft is rotatably connected to the slider, and the connection point of the first telescopic part and the connection point of the tool holder are located on both sides of the rotation fulcrum of the support shaft, the whole forms a lever. When the first telescopic part provides driving force, it is more labor-saving. After the riveting is completed, the first telescopic part retracts into the first fixed part, and the top of the support shaft rotates towards the workpiece positioning seat to reset.

[0010] As a further improvement to the above technical solution, the second driving assembly includes a second telescopic driving member. The second telescopic driving member has a second fixed part and a second telescopic part that moves in a straight line on the second fixed part. The second fixed part is rotatably connected to the worktable, and the second telescopic part is rotatably connected to the end of the tool holder away from the blade. The rotation axis of the second fixed part and the rotation axis of the second telescopic part are both parallel to the rotation axis of the support shaft. During riveting, the second telescopic part retracts to the second fixed part, directly driving the blade to rotate upward through the tool holder. Since the tool holder is rotatably connected to the support shaft, the second telescopic part that provides driving force to the tool holder and the working blade are located on both sides of the tool holder's rotation fulcrum, forming a lever, reducing the driving force required by the second telescopic part, making it more labor-saving. After riveting is completed, the second telescopic part extends out of the second fixed part, and the blade rotates downward to reset.

[0011] As a further improvement to the above technical solution, the clamping mechanism includes a fixed base, a lifting drive component, and a pressing die. The fixed base is connected to the worktable, and the lifting drive component is also connected to the worktable. The lifting drive component drives the pressing die, which can move vertically. The pressing die is the clamping end. When positioning the workpiece, the lifting drive component drives the pressing die downwards, pressing and positioning the workpiece on the workpiece positioning seat. When releasing the workpiece positioning, the lifting drive component drives the pressing die upwards.

[0012] As a further improvement to the above technical solution, a limiting plate is connected to the fixed base, and a downwardly extending pressure rod is connected to the limiting plate. The bottom end of the pressure rod abuts against the top side of the tool holder. The pressure rod on the limiting plate abuts against the tool holder, which can limit the range of motion of the tool holder, thereby limiting the stroke of the blade.

[0013] As a further improvement to the above technical solution, a limiting groove is provided on the side wall of the workpiece positioning seat, the limiting groove extending upward to the top side of the workpiece positioning seat, and the cutting edge extending into the limiting groove. The limiting groove can further limit the horizontal displacement of the cutting edge, thereby improving the stability of the cutting edge during rotation, especially during riveting, and improving the quality of riveting.

[0014] As a further improvement to the above technical solution, multiple riveting mechanisms are arranged around the workpiece positioning seat. These multiple riveting mechanisms allow for simultaneous riveting at different positions on the workpiece, further improving riveting efficiency. Attached Figure Description

Detailed Implementation

[0020] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A riveting removal machine includes a worktable 500, on which are provided: a workpiece positioning seat 100, the top surface of which is provided with a workpiece positioning groove 110; a clamping mechanism having a clamping end that can move up and down, the clamping end being located directly above the workpiece positioning seat 100; and a riveting removal mechanism including a movable device and a blade 310, the blade 310 having an arc-shaped cutting edge 311, the movable device being able to drive the blade 310 to rotate and cause the blade 310 to move in a direction closer to or away from the workpiece positioning seat 100.

[0022] The workpiece to be derived is placed into the workpiece positioning groove 110. The clamping end of the clamping mechanism moves downward to press the workpiece onto the workpiece positioning seat 100. The moving device drives the blade 310 to rotate, so that the arc-shaped blade 311 abuts against the edge of the rivet. As the blade 310 continues to rotate, the blade 311 lifts the cap on the rivet. The moving device continues to drive the blade 310 to move away from the workpiece positioning seat 100, destroying the cap of the rivet and completing the derivation. This greatly improves the efficiency and stability of derivation, reduces labor, and increases production efficiency.

[0023] The movable device is mainly used to drive the blade 310 to rotate and slide, so that the cutting edge 311 can remove the rivet cap outward. It can adopt various structural forms, such as directly using a driving component with three mutually perpendicular degrees of freedom to drive the blade 310. Through the combined motion of the three degrees of freedom, the blade 310 can be driven to insert into the rivet cap gap and move outward. In this embodiment, the movable device includes a support shaft 320, a slider 330, a handle 340, a first driving assembly, and a second driving assembly. The slider 330 is slidably connected to the worktable 500, and the support shaft 320 is rotatably connected to the slider 330. The rotation axis of the support shaft 320... The line extends horizontally. The first driving component drives and connects to the support shaft 320, and the first driving component can drive the support shaft 320 to rotate. One end of the tool holder 340 is connected to the part of the support shaft 320 located above the slider 330. The rotation axis of the tool holder 340 is parallel to the support shaft 320. The blade 310 is connected to the end of the tool holder 340 near the support shaft 320. The second driving component drives and connects to the end of the tool holder 340 away from the support shaft 320. The second driving component can drive the tool holder 340 to rotate and cause the slider 330 to slide in a direction away from or near the workpiece positioning seat 100. When riveting is required, the second drive assembly drives the blade 310 to rotate via the tool holder 340 and pulls the slider 330 away from the workpiece positioning seat 100. During this process, the first drive assembly drives the support shaft 320 to rotate. Through the combined motion of the rotation of the support shaft 320 and the rotation of the tool holder 340, the blade 311 is always in contact with the cap of the rivet, thus successfully destroying the cap. In this way, the rotation fulcrum of the blade 310 moves with the action of the blade 311 in riveting, preventing the blade 311 from disengaging from the rivet point and greatly improving the stability and quality of riveting.

[0024] The first driving component is mainly used to drive the support shaft 320 to rotate on the slider 330, and can also provide rotational driving force to the support shaft 320 during sliding movement. For example, it can be directly achieved by using a combination of translational driving component and swing driving component. In this embodiment, the first driving component includes a first telescopic driving component 350. The first telescopic driving component 350 has a first fixed part and a first telescopic part that moves in a straight line on the first fixed part. The first fixed part is rotatably connected to the worktable 500. A first clearance opening is provided on the worktable 500 at a position opposite to the support shaft 320. The bottom end of the support shaft 320 passes through the first clearance opening and extends into the worktable 500. The bottom end of the support shaft 320 is connected to a transition block that extends in a direction away from the workpiece positioning seat 100. The first telescopic part is rotatably connected to the transition block. The rotation axis of the first fixed part and the rotation axis of the first telescopic part are both parallel to the rotation axis of the support shaft 320. During riveting, the first telescopic part extends out of the first fixed part, and the top of the support shaft 320 rotates away from the workpiece positioning seat 100, lifting the rotation fulcrum of the blade 310 upward, thereby better inserting the blade 311 into the rivet point. Since the support shaft 320 is rotatably connected to the slider 330, and the connection point of the first telescopic part and the connection point of the tool holder 340 are located on both sides of the rotation fulcrum of the support shaft 320, the whole forms a lever. When the first telescopic part provides driving force, it is more labor-saving. After the riveting is completed, the first telescopic part retracts to the first fixed part, and the top of the support shaft 320 rotates back to the position closer to the workpiece positioning seat 100.

[0025] The second drive assembly is mainly used to provide the power for the slider to slide and the driving force for the rotation of the tool holder 340. It can adopt various structural forms, such as driving the slider 330 and the tool holder 340 to translate through independent translation drive members, and setting a swing drive member on the translation drive member that drives the tool holder 340 to rotate. In this embodiment, the second drive assembly includes a second telescopic drive member 360. The second telescopic drive member 360 has a second fixed part and a second telescopic part that moves in a straight line on the second fixed part. The second fixed part is rotatably connected to the worktable 500, and the second telescopic part is rotatably connected to the end of the tool holder 340 away from the blade 310. The rotation axis of the second fixed part and the rotation axis of the second telescopic part are both parallel to the rotation axis of the support shaft 320. During riveting, the second telescopic part retracts to the second fixed part, and the blade 310 is directly driven to rotate upward through the handle 340. Since the handle 340 is rotatably connected to the support shaft 320, the second telescopic part that provides driving force to the handle 340 and the working blade 311 are located on both sides of the rotation fulcrum of the handle 340, forming a lever, which reduces the driving force required by the second telescopic part and makes it more labor-saving. After the riveting is completed, the second telescopic part extends out of the second fixed part, and the blade 310 rotates downward to reset.

[0026] To fix the workpiece relatively on the workpiece positioning seat 100, the clamping mechanism includes a fixed seat 210, a lifting drive 220, and a pressing mold. The fixed seat 210 is connected to the worktable 500, and the lifting drive 220 is also connected to the worktable 500. The lifting drive 220 drives the pressing mold, which moves vertically. The pressing mold is the clamping end. When positioning the workpiece, the lifting drive 220 drives the pressing mold downwards, clamping and positioning the workpiece on the workpiece positioning seat 100. When releasing the workpiece positioning, the lifting drive 220 drives the pressing mold upwards.

[0027] Furthermore, a limiting plate 400 is connected to the fixed base 210, and a downwardly extending pressure rod is connected to the limiting plate 400. The bottom end of the pressure rod abuts against the top side of the tool holder 340. The pressure rod on the limiting plate 400 abuts against the tool holder 340, which can limit the range of motion of the tool holder 340, thereby limiting the travel of the blade 310.

[0028] Furthermore, the side wall of the workpiece positioning seat 100 is provided with a limiting groove 120, which extends upward to the top side of the workpiece positioning seat 100, and the cutting edge 311 extends into the limiting groove 120. The limiting groove 120 can further limit the horizontal displacement of the cutting edge 310, thereby improving the stability of the cutting edge 310 when rotating, especially during riveting, and improving the riveting quality.

[0029] Workpieces typically have multiple rivet points. To improve riveting efficiency, multiple riveting mechanisms are arranged around the workpiece positioning seat 100. These multiple riveting mechanisms allow for simultaneous riveting at different locations on the workpiece, further enhancing riveting efficiency.

[0030] In practical applications, the first telescopic drive component 350, the second telescopic drive component 360, and the lifting drive component 220 are all drive structures that can provide movement in a straight line. They can be of various structural forms, such as being driven by a cylinder, an electric lead screw, or a hydraulic cylinder.

[0031] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
