Description

Technical Field

[0001] This utility model relates to the technical field of grinding and cutting, and specifically to a deburring and grinding cutting device for bottle caps. Background Technology

[0002] In industries such as beverage packaging and daily chemical products, bottle caps are key sealing components, and their processing quality directly affects product sealing and user experience. With the increasing demand for automated production, the precision and efficiency requirements for deburring and removing residual sprue from bottle caps are rising. In existing technologies, such processing often relies on traditional lathes or specialized equipment, with manual loading and unloading combined with fixed cutting tools for grinding. In specific applications, operators need to manually install the bottle cap workpiece onto a high-precision spindle chuck, adjust the tool position, and start the equipment to rotate and process. After completion, the workpiece is manually removed. Although this mode can meet basic deburring requirements, traditional equipment has a relatively simple structure, is intuitive to operate, requires less skill from operators, and has controllable initial investment costs. It is suitable for small-batch production or scenarios where processing precision requirements are not high. At the same time, the fixed cutting tool design provides stability during grinding in one direction, which can meet the basic functional requirements of bottle caps in the early packaging industry.

[0003] However, as the market demands higher product quality and production efficiency, manual production is inefficient, and the loading, unloading, and adjustment processes are time-consuming, making it difficult to adapt to large-scale continuous production. Traditional chucks, when used for workpieces with threaded structures, are prone to slippage due to insufficient friction on the contact surface or inaccurate positioning during processing, resulting in incomplete burr removal or surface damage. Furthermore, the equipment lacks integration, with each step of loading, unloading, processing, and transfer operating independently, resulting in low automation and making it difficult to meet the modern packaging industry's requirements for efficient, high-precision, and low-loss production. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a deburring and grinding cutting device for bottle caps. The device achieves automated workpiece transfer through a loading transfer component, a unloading transfer component, and a comprehensive conveying component. The loading transfer component transports the bottle caps to be processed to the feeding port via a loading guide rail and a loading drive module. The unloading transfer component transfers the processed workpieces to the unloading port via a unloading guide rail and an unloading drive module. The first and second transfer modules of the comprehensive conveying component further connect the loading and unloading processes, avoiding the inefficiency caused by manual loading and unloading in traditional technologies and significantly improving production cycle time. The spring and arc-shaped surface structure at one end of the internal clamping shaft, combined with the rebound force generated by the spring being squeezed by the inner pipe wall and the rotation restriction design of the arc-shaped side engaging the pipe thread, effectively increases the static friction with the inner pipe of the workpiece. This solves the workpiece slippage problem caused by the single chuck fixing method in traditional methods, ensuring stable workpiece position during grinding and cutting, and avoiding incomplete burr removal or surface damage. The first and second cutting tools of the cutting tool assembly are arranged vertically, and are coordinated with the X-axis (first linear module) and Y-axis (second linear module) of the displacement adjustment module for multi-directional collaborative machining of different grinding surfaces of the workpiece. This eliminates the need for repeated adjustments to the workpiece angle and solves the problem of low efficiency in traditional single-tool designs. The displacement adjustment module adjusts the displacement of the tooling clamping plate, and is linked with the high-precision spindle speed of the rotary mechanism through the CNC central control system to match machining parameters, avoiding uneven cutting or overload problems. The anti-collision module of the loading assembly uses a limit optical axis and a return spring design to provide buffer protection when the gripper grasps the workpiece, avoiding equipment damage caused by rigid collisions. The cylinder plate and connecting pipe of the unloading assembly drive the suction cup to grasp the workpiece, and with the suction control of the external air source driver, stable release and transfer of the workpiece are achieved. The cutting and grinding mechanism, rotary mechanism, and transfer mechanism are integrated into the lathe and uniformly scheduled by the central control system, reducing independent operation of each link, improving the degree of automation, and solving the problem of insufficient integration in traditional equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A deburring and grinding device for bottle caps includes a lathe providing a workspace for rotating workpieces.

The grinding mechanism includes a displacement adjustment module mounted on the worktable via a mounting base, a tooling clamp on the displacement adjustment module, a grinding tool assembly at one end of the tooling clamp, a loading assembly on one side of the grinding tool assembly, and a unloading assembly on one side of the loading assembly.

[0010] The unloading assembly includes a cylinder encoder plate mounted on the tooling clamp, a connecting pipe mounted on the cylinder encoder plate, and a suction cup mounted at the output end of the connecting pipe.

[0011] The transfer mechanism includes a loading transfer component, a unloading transfer component located on one side of the loading transfer component, and a comprehensive conveying component located at one end of the unloading transfer component. The loading transfer component is used to orderly transfer the workpiece to the picking station of the loading component. The unloading transfer component is used to cooperate with the displacement adjustment module to transfer the workpiece. The comprehensive conveying component is used to cooperate with the loading transfer component and the unloading transfer component to transfer the workpiece.

[0012] The feeding and transfer assembly includes a feeding guide rail, a feeding drive module located at the feeding end of the feeding guide rail, and a feeding port located at the other end of the feeding guide rail.

[0013] The material transfer assembly includes a material feeding guide rail, a material feeding drive module located at the material feeding guide rail outlet end, and a material discharge port located at the other end of the material feeding guide rail.

[0014] The integrated conveying assembly includes a mounting frame, a first transfer module mounted on the mounting frame, and a second transfer module mounted on the first transfer module.

[0015] The beneficial effects of this utility model are as follows: 1.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings: like Figure 1-7As shown, this utility model relates to a deburring and grinding cutting device for bottle caps, including a lathe 1, which provides a working space for rotating workpieces. A cutting and grinding mechanism 2 is provided on the worktable 10 of the lathe 1. This cutting and grinding mechanism 2 is used to grind and process the workpiece. The cutting and grinding mechanism 2 includes a displacement adjustment module 20 mounted on the worktable 10 via a mounting base 21, a tooling clamping plate 22 mounted on the displacement adjustment module 20, a grinding tool assembly 23 located at one end of the tooling clamping plate 22, and a feeding assembly 24 located on one side of the grinding tool assembly 23. The unloading assembly 25 is located on one side of the loading assembly 24. The displacement adjustment module 20 is used to adjust the working position of the tooling clamp 22 of the cutting and grinding mechanism 2. The tooling clamp 22 is used to provide the mounting base. The grinding tool assembly 23 is used to grind the sprue adhesion part of the workpiece. The loading assembly 24 is used to clamp the workpiece and load it to the processing position. The unloading assembly 25 is used to remove the ground workpiece and transfer it. The mounting base 21 is provided with an inclined surface 210. When the displacement adjustment module 20 is installed on the inclined surface 210, it forms an inclined angle with the table surface 10, which facilitates the adjustment of the workpiece. The workpiece is transferred for processing; a transfer mechanism 3 is provided on one side of the lathe 1, which is used to transfer the processed workpiece; the lathe 1 is provided with a rotary mechanism 11 for grinding and cutting, and the power output end of the rotary mechanism 11 is provided with an inner locating shaft 110. The inner locating shaft 110 is used to limit the workpiece and cooperate with the grinding and cutting operation of the cutting and grinding mechanism 2. The lathe 1 also includes a bed 12 and a control system 13. The high-precision spindle 113 of the rotary mechanism 11 drives the inner locating shaft 110 to rotate the workpiece, cooperating with the cutting and grinding mechanism 2; specifically The rotating mechanism 11 is built into the main box 120 of the bed 12 and includes a motor 111, a transmission gear set 112 and a high-precision spindle 113. The motor 111 transmits power to the high-precision spindle 113 through gear transmission. The control system 13 precisely controls the speed of the high-precision spindle 113 through a numerical control device (CNC) or a programmable logic controller (PLC) and links with the displacement adjustment module 20 of the cutting and grinding mechanism 2 to ensure the matching of machining parameters (such as speed and feed rate). Its motion trajectory is scheduled by the overall control system integrated by the CNC of the lathe 1.

[0025] like Figure 1-3As shown, one end of the inner clamping shaft 110 is circumferentially provided with several spring pieces 1100. Each spring piece 1100 has a protrusion on its outer side, with one side of the protrusion being an arc-shaped surface to facilitate the insertion of the inner clamping shaft 110 into the inner channel of the workpiece for positioning. The other end of the inner clamping shaft 110 is fixedly connected to a high-precision spindle 113. When the end with the spring piece 1100 is inserted into the inner channel of the workpiece, the inner channel wall presses against the arc-shaped surface, causing the spring piece 1100 to generate a rebound force against the inner channel wall. This increases the static friction between the inner clamping shaft 110 and the inner channel of the workpiece, allowing the workpiece to... The bottle cap component is intended for use in bottling. There are threads on the inner pipe wall of the workpiece, and there are gaps between each spring 1100. The side of the arc-shaped surface will get stuck in the thread. Therefore, the arc-shaped surface of each spring 1100 and the thread restrict rotation, so that the workpiece is stationary on the inner connecting shaft 110. By setting the parameters of the control system 13, the speed of the motor 111 of the rotating mechanism 11 is controlled. The grinding friction force of the cutting tool on the workpiece is less than the static friction force of the inner connecting shaft 110 contacting the inner pipe of the workpiece, so as to keep the workpiece from shifting during grinding.

[0026] like Figure 1-5As shown, the displacement adjustment module 20 includes a base 200 and a first linear module 201 and a second linear module 202 mounted on the base 200. The first linear module 201 and the second linear module 202 form a cross-stacked layout, which facilitates the adjustment of the working position of the cutting and grinding mechanism 2. Each of the first linear module 201 and the second linear module 202 includes a guide rail, a slider, a drive motor, a transmission component, a sliding connecting plate, a coupling, a mechanical stop, and a feedback sensor. The base 200 is made of aluminum alloy profile or steel. Two parallel guide rails are fixed to both sides of the base 200 by bolts. Each guide rail is equipped with a... A sliding slider, with embedded balls to reduce friction, is connected to a sliding connecting plate spanning both sides of the slider and secured with screws, forming a moving platform that supports the tooling clamp 22. A drive motor is mounted at one end of the base 200, and its output shaft is directly connected to the screw end of a ball screw via a coupling. The nut portion of the ball screw is fixed to the sliding connecting plate. When the drive motor starts, the screw rotates, causing the nut to move axially, thereby driving the sliding connecting plate and the slider to move linearly along the guide rails. Mechanical stops are respectively located at the ends of the guide rails at both ends of the base 200, and are fixed with bolts to limit movement and prevent the slider from overshooting due to control system 13 malfunction or inertia. The reading head of the feedback sensor is mounted on the sliding connecting plate, while the scale is fixed to the side of the base 200. The sensor detects the position deviation of the connecting plate in real time and transmits the signal to the control system 13, forming a closed-loop control with the motor encoder to ensure displacement accuracy. The tooling clamp 22 is fixed to the top surface of the sliding connecting plate of the second linear module 202 by screws. Its mounting holes are long slots or arrayed to facilitate adjustment of the installation position. The tooling clamp 22 is a cuboid, and one side of the tooling clamp 22 is provided with several tooling slots 220. The tooling slots 220 pass through both ends of the tooling clamp 22. The bolts are used to fix other assembly parts in the cutting and grinding mechanism 2. Specifically, the first linear module 201 adjusts the displacement of the tooling clamp 22 perpendicular to the inner connecting shaft 110, and the second linear module 202 adjusts the displacement of the tooling clamp 22 coaxial with the inner connecting shaft 110. For ease of understanding, the adjustment displacement direction of the first linear module 201 is set as the X direction, and the direction of movement of the feeding assembly 24 towards the inner connecting shaft 110 after taking the material is taken as positive. The adjustment displacement direction of the second linear module 202 is set as the Y direction, and the direction of movement of the grinding tool assembly 23 away from the inner connecting shaft 110 is taken as positive.

[0027] like Figure 5-6As shown, the grinding and cutting tool assembly 23 includes a first tool holder 230, a first limiting plate 231 disposed on the first tool holder 230, a first cutting tool 232 disposed between the first tool holder 230 and the first limiting plate 231, a second tool holder 233 disposed on one side of the first tool holder 230, a second limiting plate 234 disposed on the second tool holder 233, and a second cutting tool 235 disposed between the second tool holder 233 and the second limiting plate 234. The cutting edge of the first cutting tool 232 is square. The tool holders 230 and 233 are arranged perpendicular to the cutting edge direction of the second cutting tool 235 to facilitate grinding of the residual sprue area of ​​the workpiece by the first cutting tool 232 and the second cutting tool 235. Both the first tool holder 230 and the second tool holder 233 are equipped with limiting parts that mate with the tooling groove 220 and are fixed to the tooling clamp 22 by bolts. The grinding position of the first cutting tool 232 and the second cutting tool 235 is adjusted by adjusting the relative positions of the first tool holder 230 and the second tool holder 233 in the tooling groove 220. During the cutting process, the relative position of the first cutting tool 232 on the first tool holder 230 and the inner connecting shaft 110 is adjusted by the displacement adjustment module 20, so that the first cutting tool 232 is aligned with and contacts the first grinding surface of the workpiece. The rotating mechanism 11 drives the inner connecting shaft 110 to rotate synchronously, and cooperates with the second linear module 202 to drive the first cutting tool 232 on the tooling clamp 22 to reciprocate along the Y direction, so that the first cutting tool 232 grinds along the first grinding surface, completing the grinding process of the first grinding surface of the workpiece. The relative position of the second cutting tool 235 on the second tool holder 233 and the inner connecting shaft 110 is adjusted by the displacement adjustment module 20, so that the second cutting tool 235 is aligned with and contacts the second grinding surface of the workpiece. The rotating mechanism 11 drives the inner connecting shaft 110 to rotate synchronously, and cooperates with the second linear module 202 to drive the second cutting tool 235 on the tooling clamp 22 to reciprocate along the Y direction, so that the second cutting tool 235 grinds along the second grinding surface, completing the grinding process of the second grinding surface of the workpiece.

[0028] like Figure 5-6As shown, the feeding assembly 24 includes an anti-collision module 240 mounted on the tooling clamping plate 22, a finger gripper motor 241 mounted at one end of the anti-collision module 240, and a gripper 242 mounted at the output end of the finger gripper motor 241. The anti-collision module 240 includes at least one limiting straight plate 2400, two limiting optical shafts 2401 passing through the limiting straight plate 2400, and a return spring 2402 sleeved on the limiting optical shafts 2401. The limiting straight plate 2400 is fixedly connected to the tooling clamping plate 22 by bolts. The function of the anti-collision module 240 is that when the gripper 242 is gripping a workpiece, it may come into contact with and collide with other components. At this time, the limiting optical shafts 2401 can pass through the limiting straight plate 2400 and retract, thereby driving the finger gripper motor 242. 41 and gripper 242 retract to avoid rigid collision with the component and damage. The force of the return spring 2402 keeps gripper 242 stable when in contact with the workpiece, preventing direct detachment of the gripper motor 241 and gripper 242 from the workpiece upon contact. Specifically, the gripper motor 241 includes a motor, gearbox, and rack. Gripper 242 is fixed to one end of the rack by bolts or slots. The gearbox is the power conversion hub, including an input shaft connected to the motor output, a gear set meshing with the input shaft, and an output shaft meshing with the gear set. One end of the output shaft is connected to a symmetrically distributed rack via a coupling. The meshing of the gears and rack converts rotational motion into linear motion, driving gripper 242 to move axially in a concentric manner. During operation, the motor rotates forward, driving the input shaft of the gearbox to rotate. After speed change via the gear set, the output shaft drives the rack to move synchronously, causing the gripper 242 to open. The first linear module 201 (X-axis) of the displacement adjustment module 20 drives the tooling clamping plate 22 to move until the axis of the loading assembly 24 is collinear with the center of the workpiece at the loading port 3001 on the loading transfer assembly 30. The second linear module 202 (Y-axis) drives the loading assembly 24 on the tooling clamping plate 22 to approach the loading port 3001. When the open gripper 242 touches the loading port 3001, the Y-axis movement stops, the motor reverses, and the gripper 242 closes to grab the workpiece. After grabbing, the second linear module 202 (Y-axis) drives the loading assembly 24 on the tooling clamping plate 22 to move away from the loading port 3001. The workpiece is removed from the feeding port 3001. Then, the first linear module 201 (X-direction) of the displacement adjustment module 20 drives the tooling clamping plate 22 to move in a direction perpendicular to the inner connecting shaft 110, sending the gripper 242 holding the workpiece to the collinear position of the high-precision spindle 113 of the rotating mechanism 11. The second linear module 202 (Y-direction) drives the loading component 24 on the tooling clamping plate 22 to approach the inner connecting shaft 110 until the inner tube of the workpiece is limited to the inner connecting shaft 110 with one end of the spring piece 1100. Then, the finger gripper motor 241 drives the gripper 242 to open and release the workpiece. The second linear module 202 (Y-direction) drives the loading component 24 on the tooling clamping plate 22 to disengage from the inner connecting shaft 110, completing one loading process.

[0029] like Figure 5-6 As shown, the unloading assembly 25 includes a cylinder clamping plate 250 mounted on the tooling clamping plate 22, a connecting pipe 251 mounted on the cylinder clamping plate 250, and a suction cup 252 located at the output end of the connecting pipe 251. The connecting pipe 251 is connected to an external air source driver. After the workpiece is ground, the first linear module 201 (X-axis) drives the unloading assembly 25 on the tooling clamping plate 22 to move to one end of the internal clamping shaft 110, aligning the suction cup 252 with the workpiece. The second linear module 202 (Y-axis) drives the suction cup 252 to approach and contact the workpiece. The external air source driver causes the suction cup 252 to generate suction force to clamp the workpiece. The linear module 202 (Y direction) drives the workpiece on the suction cup 252 to disengage from the inner clamping shaft 110. Then, the first linear module 201 (X direction) drives the unloading assembly 25 on the tooling clamping plate 22 to move to the side of the unloading transfer assembly 31 discharge port 3101, so that the workpiece is aligned with the discharge port 3101. The second linear module 202 (Y direction) drives the suction cup 252 to approach the discharge port 3101. After the workpiece is completely placed into the discharge port 3101, the external air source driver is turned off, so that the suction cup 252 no longer generates suction force and the workpiece is disengaged from the suction cup 252. The workpiece falls into the discharge port 3101 and is transferred away by the unloading guide rail 310.

[0030] like Figure 1-2As shown in Figure 7, the transfer mechanism 3 includes a loading transfer component 30, a unloading transfer component 31 located on one side of the loading transfer component 30, and a comprehensive conveying component 32 located at one end of the unloading transfer component 31. The loading transfer component 30 is used to orderly transfer the workpiece to the picking station of the loading component 24. The unloading transfer component 31 is used to cooperate with the displacement adjustment module 20 to transfer the workpiece. The comprehensive conveying component 32 is used to cooperate with the loading transfer component 30 and the unloading transfer component 31 in the transfer operation of the workpiece. The loading transfer component 30 includes a loading guide rail 300, a loading drive module 301 located at the feeding end 3000 of the loading guide rail 300, and a picking port 3001 located at the other end of the loading guide rail 300. The unloading transfer component 31 includes a unloading guide rail 310 and a unloading port located at the discharge end 3100 of the unloading guide rail 310. The drive module 311 and the discharge port 3101 located at the other end of the unloading guide rail 310; the integrated conveying assembly 32 includes a mounting frame 320, a first transfer module 321 located on the mounting frame 320 and a second transfer module 322 located on the first transfer module 321. The second transfer module 322 is used to transfer the workpiece to the area below the loading transfer assembly 30, and the workpiece is transferred to the receiving port of the loading transfer assembly 30 by a robot. The first transfer module 321 is used to transfer the workpiece placed down from the discharge end 3100 of the unloading transfer assembly 31. The first transfer module 321 and the second transfer module 322 both include a drive motor, a transmission belt, a conveyor roller and a material conveyor belt. The drive motor outputs power to drive the transmission belt to rotate the conveyor roller. The material conveyor belt is sleeved on the conveyor roller located at both ends of the mounting frame 320.

[0031] Working principle: The cutting and grinding mechanism 2 and the rotating mechanism 11 on the worktable 10 work together to complete the automated grinding and cutting operation of the workpiece; specifically as follows: First, the loading and transfer component 30 of the transfer mechanism 3 transfers the workpiece to be processed to the receiving port of the loading guide rail 300 through the second transfer module 322 of the integrated conveying component 32. Then, the loading drive module 301 transports the workpiece along the loading guide rail 300 to the picking port 3001. At this time, the loading component 24 of the cutting and grinding mechanism 2 starts: During operation, the motor rotates forward to drive the input shaft of the gearbox to rotate. After the gear set speed change, the output shaft drives the rack to move synchronously, so that the gripper 242 opens. The first linear module 201 (X direction) of the displacement adjustment module 20 drives the tooling clamping plate 22 to move until the axis of the loading component 24 is collinear with the center of the workpiece at the picking port 3001 on the loading and transfer component 30. The second linear module 202 (Y direction) drives the tooling clamping plate The loading component 24 on the tooling clamp 22 approaches the feeding port 3001. When the open gripper 242 touches the feeding port 3001, the Y-axis movement stops, the motor reverses, and the gripper 242 closes to grab the workpiece. After grabbing, the second linear module 202 (Y-axis) drives the loading component 24 on the tooling clamp 22 away from the feeding port 3001, so that the workpiece is removed from the feeding port 3001. Then, the first linear module 201 (X-axis) of the displacement adjustment module 20... The drive tooling clamping plate 22 moves in a direction perpendicular to the inner connecting shaft 110, sending the workpiece-holding jaws 242 to a position where they are collinear with the high-precision spindle 113 of the rotating mechanism 11. The second linear module 202 (Y-axis) drives the loading assembly 24 on the tooling clamping plate 22 to approach the inner connecting shaft 110 until the inner channel of the workpiece is positioned relative to the inner connecting shaft 110 with the spring piece 1100 at one end. Then, the finger gripper motor 241 drives the gripper 242. When the workpiece is released, the second linear module 202 (Y direction) drives the loading assembly 24 on the tooling clamp 22 to disengage from the inner connecting shaft 110. When the inner pipe of the workpiece is inserted into the end of the spring piece 1100 of the inner connecting shaft 110, the arc-shaped surface on the outer side of the spring piece 1100 is squeezed by the inner pipe wall and generates a rebound force. The side of the arc-shaped surface at the gap of the spring piece 1100 is inserted into the pipe thread, forming rotation restriction and static friction fixation, ensuring that the workpiece does not shift due to grinding force during subsequent processing.After loading is completed, the control system 13 starts the rotating mechanism 11. The motor 111 drives the high-precision spindle 113 to rotate through the transmission gear set 112. The inner clamping shaft 110 drives the workpiece to rotate synchronously. At this time, during the grinding and cutting operation, the position of the first cutting tool 232 on the first tool holder 230 is adjusted by the displacement adjustment module 20 so that the first cutting tool 232 is aligned with and contacts the first grinding surface of the workpiece. The rotating mechanism 11 drives the inner clamping shaft 110 to rotate synchronously, and cooperates with the second linear module 202 to drive the first cutting tool 232 on the tooling clamp 22 to reciprocate along the Y direction. The movement causes the first cutting tool 232 to grind along the first grinding surface, completing the grinding process of the first grinding surface of the workpiece. The position of the second cutting tool 235 on the second tool holder 233 is adjusted by the displacement adjustment module 20 so that the second cutting tool 235 is aligned with and contacts the second grinding surface of the workpiece. The rotating mechanism 11 drives the inner connecting shaft 110 to rotate synchronously, and cooperates with the second linear module 202 to drive the second cutting tool 235 on the tooling clamp 22 to reciprocate along the Y direction, so that the second cutting tool 235 grinds along the second grinding surface, completing the grinding process of the second grinding surface of the workpiece. After grinding, once the workpiece has been ground, the first linear module 201 (X-axis) drives the unloading assembly 25 on the tooling clamp 22 to move to one end of the inner clamping shaft 110, aligning the suction cup 252 with the workpiece. The second linear module 202 (Y-axis) drives the suction cup 252 to approach and contact the workpiece. An external air source driver causes the suction cup 252 to generate suction force to hold the workpiece. The workpiece on the second linear module 202 (Y-axis) then disengages from the inner clamping shaft 110. Then, the first linear module... The unloading component 25 on the tooling clamp 22 is moved to the side of the unloading transfer component 31 discharge port 3101, so that the workpiece is aligned with the discharge port 3101. The second linear module 202 (Y direction) drives the suction cup 252 to approach the discharge port 3101. After the workpiece is completely placed into the discharge port 3101, the external air source driver is turned off, so that the suction cup 252 no longer generates suction force and the workpiece is removed from the suction cup 252. The workpiece falls into the discharge port 3101 and is transferred away by the unloading guide rail 310.
