Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to automated circular cutting mechanisms. Background Technology

[0002] With the development of industrial production, the demand for mass-produced parts such as automotive gearbox housings and engine casings / hydraulic valve bodies is increasing, and the requirements for machining accuracy and efficiency of various parts are also becoming higher. In the machining process of housing parts, the cutting of surface coaxiality holes is crucial. Precise circular cutting ensures the assembly quality and performance of parts, thereby improving the stability and reliability of the entire mechanical equipment. Currently, machining technology is constantly advancing, and its application range is becoming increasingly wide, playing an indispensable role in industrial production.

[0003] In existing technologies, the cutting of coaxial holes on the surface of box-type parts typically employs two methods: manual cutting and simple mechanical cutting. Manual cutting relies primarily on workers holding cutting tools and operating based on experience and skill. This method offers a degree of flexibility and can be adjusted according to the actual situation. Simple mechanical cutting utilizes simple mechanical devices to assist in the cutting process, such as using fixed tracks and cutters to cut straight lines or simple curves, which can improve cutting efficiency and accuracy to some extent.

[0004] However, both manual and simple mechanical cutting have significant drawbacks. Manual cutting requires a high level of skill from the worker and is easily affected by human factors, making it difficult to guarantee cutting accuracy and prone to deviations. Simple mechanical cutting often requires complex molds or positioning devices for circular cutting, making the operation cumbersome and unable to achieve circular cuts of different diameters, thus failing to meet diverse processing needs. Summary of the Invention

[0005] To address the challenges of achieving high-precision coaxiality of parts during cutting and the inability to adjust the diameter of the circular cut hole in a timely manner, this application provides an automated circular cutting mechanism.

[0006] The automated circular cutting mechanism provided in this application adopts the following technical solution: An automated circular cutting mechanism includes a base, the base having at least a plurality of processing positions, each processing position consisting of a drive unit, a transmission unit, and a clamping cutting unit. The drive unit is disposed on the base and is used to drive the transmission unit. The transmission unit is connected to the drive unit and is used to drive the clamping cutting unit to achieve circular trajectory cutting of different diameters. The clamping cutting unit is disposed on the transmission unit and is used to cut coaxial holes on the surface of box-shaped parts.

[0007] By adopting the above technical solution, multiple processing positions are arranged on the base. Each processing position consists of a drive unit, a transmission unit, and a clamping and cutting unit. The drive unit is located on the base and can drive the transmission unit to perform transmission, providing power for the entire cutting process. The transmission unit is connected to the drive unit and can drive the clamping and cutting unit to cut along circular trajectories of different diameters, which can adapt to the cutting requirements of different sizes. The clamping and cutting unit is located on the transmission unit and can accurately cut holes with coaxiality requirements on the surface of box parts, ensuring that the cut holes meet the coaxiality standard, improving the cutting accuracy and quality, realizing automated circular cutting operation, and improving processing efficiency and product quality.

[0008] Optionally, the drive unit includes a control motor and a tray, the control motor being arranged on the base, and the output end of the control motor being located at a position off-center from the center of the tray.

[0009] By adopting the above technical solution, the control motor serves as the power source for the entire drive unit. Its output end is located off-center from the center of the tray. This eccentric setting allows the control motor to drive the tray to move in a circular trajectory around its axis after starting. This motion is transmitted to the transmission unit connected to the drive unit, which in turn drives the clamping and cutting unit to perform circular trajectory cutting of different diameters. This completes the cutting of coaxial holes on the surface of the box parts, realizing automated circular cutting operation. It also avoids the problem of difficulty in guaranteeing cutting accuracy due to human factors in manual cutting, effectively improving cutting accuracy and meeting diverse processing needs.

[0010] Optionally, the transmission unit includes a lead screw slidably arranged on a tray and a control handwheel mounted on the lead screw. The tray has a groove for the lead screw to rotate, and the center line of the groove passes through the center of the tray. The control handwheel is mounted on the end of the lead screw, and a slider is slidably arranged in the groove. The lead screw and the slider are threadedly engaged.

[0011] By adopting the above technical solution, the threaded engagement of the lead screw and slider allows the operator to rotate the control handwheel, causing the lead screw to rotate and thus driving the slider to slide within the channel. The centerline of the channel passes through the center of the tray, ensuring the stability and accuracy of the lead screw's movement. By controlling the number of rotations of the lead screw, the slider's movement distance can be precisely controlled, thereby adjusting the distance between the drive unit and the cutting point. This drives the clamping and cutting unit to achieve circular trajectory cutting of different diameters, completing the cutting of coaxial holes on the surface of box-shaped parts, meeting diverse processing needs, and offering simple operation, avoiding the use of complex molds or positioning devices.

[0012] Optionally, the clamping and cutting unit includes a support mounted on the slider and a cutting gun mounted on the support perpendicular to the surface of the machining box part.

[0013] By adopting the above technical solution, the support has a symmetrical structure design. Its symmetrical shape can hold different types of cutting guns, and it is also convenient to replace and maintain the cutting guns.

[0014] Optionally, the drive unit includes a bracket mounted on the base, and a drive motor is mounted on the bracket.

[0015] By adopting the above technical solution, the support provides stable support for the cutting gun, ensuring that the cutting gun is perpendicular to the surface of the box-shaped part being processed. During operation of the automated circular cutting mechanism, the drive unit drives the transmission unit, moving the slider and thus causing the cutting gun mounted on the support to move accordingly, achieving circular trajectory cutting of coaxial holes on the surface of the box-shaped part. This vertical installation method ensures good coaxiality of the cut holes, improving cutting accuracy. Simultaneously, the support facilitates the installation and fixation of the cutting gun, enhancing the stability of the cutting process and ensuring accurate and efficient cutting operations.

[0016] Optionally, the processing position includes a drive position, a transmission position, and an auxiliary position. The transmission unit includes a Z-shaped rotating shaft that passes through a bracket and is mounted on the drive position, a sphere mounted in the middle of the Z-shaped rotating shaft, a spherical slider sleeved on the sphere, a rotating shaft rotatably arranged between two brackets on the auxiliary position, and a main slider slidably sleeved on the rotating shaft. An arc-shaped groove is provided on one side of the bracket, and a trapezoidal lead screw is slidably arranged in the arc-shaped groove. The trapezoidal lead screw and the main slider are threaded together. A control handle is also provided at the end of the trapezoidal lead screw passing through the arc-shaped groove. The main slider and the spherical slider are slidably engaged. The sphere and the spherical slider move in a circular trajectory with the Z-shaped rotating shaft. When the control handle is rotated, the main slider reciprocates along the length direction of the spherical slider, and at the same time, the main slider reciprocates along the axial direction of the rotating shaft.

[0017] By adopting the above technical solution, the drive motor is installed in the drive position, and its output power causes the Z-shaped rotating shaft to rotate. Since the ball is installed in the middle of the Z-shaped rotating shaft, the ball and the ball slider sleeved on it will move in a circular trajectory with the Z-shaped rotating shaft. The main slider is slidably sleeved on the rotating shaft that is rotatably arranged between the two supports on both sides of the auxiliary position, and the main slider and the ball slider are in sliding engagement. An arc-shaped groove is provided on one side of the support. A trapezoidal lead screw slides in the arc-shaped groove and is threadedly engaged with the main slider. A control handle is provided at the end of the trapezoidal lead screw. When the control handle is rotated, the main slider can reciprocate along the length direction of the spherical slider by utilizing the threaded engagement between the trapezoidal lead screw and the main slider. At the same time, since the main slider is sleeved on the rotating shaft, it will also reciprocate along the axial direction of the rotating shaft. This achieves diversified and precise control of the transmission. It can transmit and convert the power of the drive motor into multi-directional motion through components such as the Z-shaped rotating shaft, sphere, and spherical slider. This provides a flexible and adjustable transmission method for subsequent cutting operations and helps to achieve circular trajectory cutting of different diameters to meet the cutting requirements of coaxial holes on the surface of box parts.

[0018] Optionally, the transmission position has a circular trajectory slider one, a circular trajectory slider two, and a circular trajectory slider three. The circular trajectory slider one is connected to the end of the spherical slider away from the main slider. The circular trajectory slider two is slidably sleeved on the circular trajectory slider one. The circular trajectory slider three is slidably sleeved on the circular trajectory slider two. A hanging spring is also provided between the circular trajectory slider two and the base.

[0019] By adopting the above technical solution, relative sliding between multiple circular trajectory sliders can be realized, which facilitates the adjustment of the cutting position according to different cutting requirements; a hanging spring is set between the second circular trajectory slider and the base. During the cutting process, the hanging spring plays a role in buffering and stabilizing, ensuring that the movement of each slider is more stable and accurate, thereby realizing circular trajectory cutting of different diameters of coaxial holes on the surface of the box part, meeting diverse processing needs.

[0020] Optionally, the clamping and cutting part includes a fixed clamp mounted on the circular trajectory slider, a spring located between the fixed clamp and the circular trajectory slider, and a nut rotatably arranged on the circular trajectory slider. The nut has a sliding groove, and a screw and a handle are connected to the side of the nut away from the circular trajectory slider. The screw and handle and the nut are connected by a pin. The nut rotates between the fixed clamps on both sides, and the cutting gun is clamped between the two fixed clamps.

[0021] By adopting the above technical solution, when the screw and handle are rotated, the screw and handle, connected to the nut by a pin, will cause the nut to rotate on the circular track slider. During the rotation of the nut, the sliding groove it has opened will produce corresponding displacement changes. When the arc part of the screw and handle is in contact with the fixing clamp, the fixing clamp and the nut are rotated and engaged by the pin. The fixing clamp is subjected to the action of the spring, and the two fixing clamps on both sides and the cutting gun are separated, which facilitates the installation or removal of the cutting gun. When the abutting part of the screw and handle is in contact with the fixing clamp, it overcomes the elastic force of the spring and causes the fixing clamp to move towards the middle, thereby forming a clamping state between the fixing clamp and the cutting gun, realizing a stable clamping of the cutting gun, ensuring the stability of the cutting gun during operation, and thus ensuring that the cutting operation can be carried out accurately and efficiently.

[0022] Optionally, the screw and handle have an arc portion and an abutment portion; the arc portion is in contact with the fixing clip, and the fixing clips on both sides are separated from the cutting gun; the abutment portion is in contact with the fixing clip, and the fixing clip and the cutting gun are clamped together.

[0023] By adopting the above technical solution, the arc part of the screw and handle is attached to the fixing clamp to separate the fixing clamps on both sides and the cutting gun, which makes it easy to adjust or replace the cutting gun; the abutting part of the screw and handle is attached to the fixing clamp to form a clamping state between the fixing clamp and the cutting gun, which can firmly fix the cutting gun and ensure that the cutting operation is stable. It can complete the circular trajectory cutting of coaxial holes on the surface of box parts.

[0024] Optionally, trapezoidal slits are formed on the ends of the two fixing clips, and the surfaces of the slits are in contact with the cutting gun.

[0025] By adopting the above technical solution, the fit of the fixing clamp to the cutting gun is enhanced, thereby improving the clamping stability of the cutting gun and ensuring the stable operation of the cutting work.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive unit drives the transmission unit to perform circular cutting of coaxial holes on the surface of the box parts. The precise cutting ensures the assembly quality and performance of the parts, thereby improving the stability and reliability of the mechanical equipment. 2. The transmission unit enables the clamping and cutting unit to perform circular trajectory cutting of different diameters, meeting diverse processing needs, eliminating the need for complex molds or positioning devices, and simplifying the operation process; 3. The use of automated cutting methods avoids the problem of inconsistent cutting accuracy caused by human factors in manual cutting, thus effectively improving cutting precision; 4. The control motor output of the drive unit is located at a position off-center from the center of the tray, and the screw and slider threaded connection of the transmission unit can precisely control the movement trajectory of the clamping and cutting unit, achieving more accurate circular cutting; 5. The clamping and cutting section separates the fixed clamp and the cutting gun through the arc and abutment parts of the screw and handle, and switches between clamping states. This facilitates the replacement of the cutting gun and improves the flexibility and efficiency of processing. 6. The Z-shaped rotating shaft is driven by a drive motor. The spheres and sphere sliders on the Z-shaped rotating shaft move in a circular trajectory. By manually rotating the control handle, the diameter of the circle formed by the rotation of the spheres and spheres can be changed. In turn, multiple circular trajectory sliders drive the cutting gun to make circular cuts of different diameters. During the overall cutting process, the rotation of the control handle can meet the needs of circular trajectory cutting of different diameters. Attached Figure Description

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail.

[0039] This application discloses an automated circular cutting mechanism. Example

[0040] See Figure 1 As shown, the overall structure provided in this application embodiment includes a base 1, a drive unit 21, a transmission unit 22, and a clamping and cutting unit 23. The drive unit 21 is disposed on the base 1, the transmission unit 22 is connected to the drive unit 21 for transmitting power, and the clamping and cutting unit 23 is disposed on the transmission unit 22. The three work together to drive the clamping and cutting unit to achieve circular trajectory cutting of different diameters, thereby cutting coaxial holes on the surface of the box part, improving the cutting accuracy and efficiency, meeting diverse processing needs, making cutting more automated, reducing the influence of human factors, improving cutting accuracy, and adapting to diverse processing needs.

[0041] See Figure 1 As shown, the drive unit 21 includes a control motor 201 and a tray 202. The control motor 201 is arranged on the base 1 and is the power source of the entire drive unit 21. Generally, a stepper motor is selected. The stepper motor has precise control performance and can accurately control the rotation speed and angle. The output end of the control motor 201 is located off-center from the center of the tray 202. The eccentric setting can make the tray 202 generate a specific motion trajectory under the drive of the motor.

[0042] See Figure 3As shown, the transmission unit 22 includes a lead screw 203 slidably arranged on the tray 202 and a control handwheel 204 mounted on the lead screw 203. The tray 202 has a groove 205 for the lead screw 203 to rotate. The centerline of the groove 205 passes through the center of the tray 202, ensuring more stable and accurate movement of the lead screw 203. The lead screw 203 is generally a ball screw, which has the advantages of high transmission efficiency and high precision. A trapezoidal lead screw 226 can also be used, as it is less expensive and suitable for applications where precision requirements are not particularly high. The control handwheel 204 is mounted at the end of the lead screw 203, allowing the operator to easily adjust the rotation of the lead screw 203 by rotating the control handwheel 204. A slider 206 is slidably installed inside the channel 205. The slider 206 has a T-shaped structure. The lead screw 203 and the slider 206 are threaded together. When the lead screw 203 rotates, the slider 206 will move in a straight line along the channel 205. The threaded connection between the lead screw 203 and the slider 206 makes the transmission more stable and precise. By controlling the number of rotations of the lead screw 203, the moving distance of the slider 206 can be precisely controlled, thereby realizing the adjustment of circular trajectories of different diameters.

[0043] See Figure 2 and Figure 3 As shown, the clamping and cutting part 23 includes a support 207 mounted on the slider 206 and a cutting gun 208 mounted on the support 207 perpendicular to the surface of the part being processed. The support 207 has a symmetrical structure, and the cutting gun 208 is arranged between the two supports 207. After the cutting gun 208 is pressed against the slider 206, the slider 206 and the support 207 are fastened by bolts. The support 207 plays the role of supporting and fixing the cutting gun 208. It is generally made of steel with good rigidity to ensure the stability of the cutting gun 208 during operation. The cutting gun 208 can be selected according to different cutting needs, such as a plasma cutting gun 208, which has a fast cutting speed and high precision and is suitable for cutting a variety of metal materials; or a laser cutting gun 208, which has higher cutting precision and a smaller heat-affected zone. The support 207 and the slider 206 are generally connected by bolts. This connection method is convenient for installation and disassembly and can ensure the firmness of the connection. The cutting gun 208 is installed perpendicular to the surface of the machined box part to ensure that the cut hole has good coaxiality.

[0044] The implementation principle of the automated circular cutting mechanism in this embodiment is as follows: The control motor 201 starts working, and because its output end is eccentrically positioned on the tray 202, it drives the tray 202 to move in a circular trajectory around its axis. Before the tray 202 rotates, the operator rotates the control handwheel 204, causing the lead screw 203 to rotate. The threaded engagement between the lead screw 203 and the slider 206 causes the slider 206 to slide within the groove 205, thereby adjusting the position of the cutting gun 208. Driven by the transmission unit 22, the cutting gun 208 cuts the coaxial holes on the surface of the box-shaped part along the set circular trajectory. This automated cutting method avoids the influence of human factors in manual cutting, greatly improving cutting accuracy. Simultaneously, by adjusting the positions of the lead screw 203 and the slider 206, the diameter of the cut circle can be flexibly adjusted to adapt to different processing requirements. Example

[0045] The difference between this embodiment and the above embodiments is: See Figure 4 and Figure 5 As shown, the drive unit 21 includes a bracket 212 mounted on the base 1 and a drive motor 211 mounted on the bracket 212. The bracket 212 serves to support the drive motor 211 and is generally made of high-strength steel structure, which can withstand the weight of the drive motor 211 and the vibration generated during operation. The drive motor 211 can also be a stepper motor or a servo motor to provide power to the entire mechanism.

[0046] See Figure 5 and Figure 6As shown, the processing station 2 consists of multiple processing points, which are mainly used for different points to cooperate in completing the work during the processing. Specifically, it includes a drive station 20, a transmission station 21, and an auxiliary station 22. The transmission unit 22 includes a Z-shaped rotating shaft 221 of a drive motor 211 that passes through the bracket 212 and is mounted on the drive station 20, a ball 222 mounted in the middle of the Z-shaped rotating shaft 221, a ball slider 223 sleeved on the ball 222, a rotating shaft 224 rotatably arranged between the two brackets 212 on the auxiliary station 22, and a main slider 225 slidably sleeved on the rotating shaft 224. Z-shaped rotating shaft 221 is generally made of alloy steel, which has high strength and toughness and can withstand large torque. The cooperation of sphere 222 and sphere slider 223 makes the movement of Z-shaped rotating shaft 221 more flexible. The rotating shaft 224 is a solid shaft to ensure its rotational stability. An arc groove is opened on one side bracket 212, and a trapezoidal lead screw 226 is slidably arranged in the arc groove. The trapezoidal lead screw 226 and the main slider 225 are threaded together. A control handle 227 is also provided at the end of the trapezoidal lead screw 226 passing through the arc groove. The main slider 225 and the ball slider 223 slide together. When the drive motor 211 drives the Z-shaped rotating shaft 221 to rotate, the ball 222 and the ball slider 223 move in a circular trajectory along the Z-shaped rotating shaft 221. When the control handle 227 is rotated, the main slider 225 moves back and forth along the length direction of the ball slider 223. At the same time, the main slider 225 moves back and forth along the axis of the rotating shaft 224. Different motion combinations can achieve circular trajectory cutting of different diameters. When cutting circles of different sizes, the cutting size can be adjusted in a timely and convenient manner.

[0047] See Figure 8 As shown, the transmission position 21 has a circular trajectory slider one 2010, a circular trajectory slider two 2020, and a circular trajectory slider three 2030. Circular trajectory slider one 2010 is connected to the end of the ball slider 223 away from the main slider 225. Circular trajectory slider two 2020 is slidably sleeved on circular trajectory slider one 2010, and circular trajectory slider three 2030 is slidably sleeved on circular trajectory slider two 2020. A hanging spring 2040 is also provided between circular trajectory slider two 2020 and the base 1. The hanging spring 2040 plays a role in buffering and resetting, ensuring that the movement of each slider 206 is more stable and accurate. The cutting gun 208 cuts along a counterclockwise circular trajectory. Circular trajectory slider one 2010 moves along the X-axis. Circular trajectory slider two 2020 moves towards the Z-axis under the influence of circular trajectory slider two 2020. Circular trajectory slider three 2030 moves towards the Y-axis under the action of circular trajectory slider two 2020.

[0048] See Figure 6 , Figure 7 and Figure 9As shown, the clamping and cutting part 23 includes a fixing clip 231 mounted on the circular track slider 2010, a spring 232 located between the fixing clip 231 and the circular track slider 2010, and a nut 233 rotatably arranged on the circular track slider 2010. The nut 233 has a sliding groove. A screw and handle 234 is connected to the side of the nut 233 away from the circular track slider 2010. The screw and handle 234 and the nut 233 are connected by a pin. The nut 233 rotates between the two fixing clips 231, and the cutting gun 208 is clamped between the two fixing clips 231. The screw and handle 234 has an arc portion 2341 and an abutment portion 2342. When the arc portion 2341 and the fixing clip 231 are in contact, the two fixing clips 231 and the cutting gun 208 are separated. When the abutment portion 2342 and the fixing clip 231 are in contact, the fixing clip 231 and the cutting gun 208 are clamped. Trapezoidal cuts are formed on the ends of the two fixing clamps 231, and the surface of the cuts is in contact with the cutting gun 208. This trapezoidal cut design can increase the contact area between the fixing clamp 231 and the cutting gun 208 and improve the stability of clamping.

[0049] The implementation principle of the automated circular cutting mechanism in this embodiment is as follows: the drive motor 211 drives the Z-shaped rotating shaft 221 to rotate, and the motion is transmitted to each slider 206 through the cooperation of the ball 222 and the ball slider 223; the operator rotates the control handle 227 to adjust the position of the main slider 225, and the main slider 225 swings back and forth along the axis of the rotating shaft 224. The main slider 225 is acted upon by the trapezoidal lead screw 226, and moves towards the axis of the trapezoidal lead screw 226 while swinging back and forth. The ball slider 223 transmits force through multiple circular trajectory sliders 206, thereby changing the diameter of the circle cut on the cutting gun 208. The hanging spring 2040 ensures the stability of the movement of each slider 206. By rotating the screw and the handle 234, the clamping and releasing of the cutting gun 208 is achieved by utilizing the cooperation of the arc part 2341 and the abutment part 2342 with the fixing clamp 231. This structure allows for greater complexity and flexibility, enabling more precise circular cutting of different diameters. It further improves cutting accuracy and adaptability, meeting the higher requirements for coaxiality hole cutting on the surface of box-shaped parts in industrial production.
