Description

Technical Field

[0001] This utility model relates to the technical field of machining, and in particular to a guide sleeve turning and milling composite equipment. Background Technology

[0002] Milling machines and lathes are common machining equipment in the mechanical field, mainly used for milling and turning workpieces. One type of tool holder is shown in the appendix to this specification. Figure 7 As shown, the workpiece is cylindrical in shape with a groove on the upper part. The existing processing technology involves first turning the outer diameter of the workpiece on a lathe to the specified size, and then transferring the turned workpiece to a milling machine to mill the groove. However, the above processing method has the following problems: the workpiece needs to be transferred from the lathe to the milling machine during processing, which requires transfer and secondary clamping. This not only increases the working time and reduces the overall processing efficiency, but also makes it easy to damage the workpiece during secondary clamping, increasing the probability of workpiece damage and making it inconvenient to use. Therefore, a processing equipment that integrates turning and milling is needed to process the above workpiece, reducing the transfer and secondary clamping of the workpiece during processing. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a guide sleeve turning and milling composite equipment that not only has turning function but also milling function, reduces the transfer and secondary clamping of workpieces during the processing, reduces the risk of crushing during guide sleeve processing, reduces labor intensity, is easy to use, and has high practicality.

[0004] This utility model discloses a guide sleeve turning and milling composite equipment, comprising a base plate and a support plate, with the support plate fixedly installed on the left side of the upper end of the base plate. It also includes a clamping mechanism, a turning mechanism, and a milling mechanism. The clamping mechanism is installed on the support plate and has a clamping and fixing function. The turning mechanism is installed on the rear side of the upper end of the base plate and has a turning function. The milling mechanism is located above the clamping mechanism and has a milling function. During guide sleeve processing, the guide sleeve is first clamped and fixed by the clamping mechanism. Then, the outer diameter of the guide sleeve is turned by the turning mechanism until the outer diameter is completed. Finally, a groove is milled on the upper part of the guide sleeve by the milling mechanism. It not only has turning functions but also milling functions, reducing the transfer and secondary clamping of the workpiece during processing, lowering the risk of damage during guide sleeve processing, reducing labor intensity, and is convenient and highly practical.

[0005] Preferably, the clamping mechanism includes a servo motor, a rotating shaft, and a three-jaw chuck A. The servo motor is fixedly mounted on the left end of the support plate, the rotating shaft is rotatably mounted on the support plate, the power output end of the servo motor is connected to the left end of the rotating shaft, and the three-jaw chuck A is fixedly mounted on the right end of the rotating shaft. The servo motor has an angle self-locking function. When clamping and fixing the guide sleeve, the left part of the guide sleeve is clamped and fixed by the three-jaw chuck A. Then, the servo motor drives the rotating shaft and the three-jaw chuck A to rotate, thereby causing the guide sleeve to rotate at high speed. Then, the turning mechanism contacts the high-speed rotating guide sleeve, thereby causing the turning mechanism to turn the surface of the guide sleeve. After the turning of the guide sleeve is completed, the servo motor drives the rotating shaft to stop rotating. At the same time, the servo motor causes the rotating shaft to self-lock at the angle, thereby fixing the three-jaw chuck A and the guide sleeve. Then, the milling mechanism mills the surface of the guide sleeve.

[0006] Preferably, the turning mechanism includes a moving mechanism, a push plate, and a cutting tool. The cutting tool is fixedly mounted on the front end of the push plate, and the push plate is mounted on the moving mechanism. The moving mechanism is used to move the push plate. When it is necessary to turn the guide sleeve surface, the moving mechanism is opened, and the moving mechanism causes the push plate to drive the cutting tool to move, thereby moving the cutting tool to contact the rotating guide sleeve, so that the cutting tool can turn the guide sleeve surface. This facilitates the turning of the guide sleeve.

[0007] Preferably, the moving mechanism includes a linear module A, a sliding plate, a vertical plate, a servo cylinder, a push rod, and a sliding rod. The linear module A is fixedly mounted on the base plate, and the sliding plate is provided on the linear module A. The linear module A is used to move the sliding plate left and right. The vertical plate is fixedly mounted on the upper end of the sliding plate. The servo cylinder is fixedly mounted on the rear end of the vertical plate. The push rod and the sliding rod are both slidably mounted on the vertical plate. The power output end of the servo cylinder is connected to the push rod, and the push plate is fixedly mounted on the front end of the push rod and the sliding rod. When turning the outer circle of the guide sleeve, the servo cylinder is turned by an external controller, which in turn drives the push rod and the push plate to move forward, so that the cutting tool contacts the outer circle of the guide sleeve. The cutting tool turns the outer circle of the rotating guide sleeve. At the same time, the linear module A drives the sliding plate to move in the left and right direction, which in turn drives the push rod, the push plate, and the cutting tool to move in the left and right direction. During the left and right movement, the cutting tool turns the left and right parts of the outer circle of the guide sleeve.

[0008] Preferably, the milling mechanism includes a lifting mechanism, a linear cross slide module, a mounting plate, and a milling device. The linear cross slide module is mounted on the lifting mechanism, which adjusts the height of the linear cross slide module. The mounting plate is mounted on the linear cross slide module, and the linear cross slide module moves the mounting plate left and right and forward and backward. The milling device is mounted on the lower end of the mounting plate and has a milling function. After the outer diameter of the guide sleeve is machined, the servo motor angle is self-locked, thereby fixing the rotating shaft and the three-jaw chuck A, and fixing the position of the guide sleeve. Then, the controller controls the lifting mechanism to lower the linear cross slide module according to the pre-input machining program, which in turn causes the mounting plate to lower the milling device until it contacts the guide sleeve. The milling device mills the surface of the guide sleeve. At the same time, the controller, according to the pre-input program, causes the linear cross slide module to move the mounting plate forward and backward and left and right along the specified machining trajectory, which in turn causes the milling device to move accordingly, so that the milling device mills a groove on the surface of the guide sleeve. This facilitates the milling process of the guide sleeve.

[0009] Preferably, the milling device includes a fixed frame, a drive motor, a rotating shaft, and a milling cutter. The fixed frame is fixedly mounted on the lower end of the mounting plate, the drive motor is fixedly mounted on the mounting plate, and the rotating shaft is rotatably mounted on the fixed frame. The power output end of the drive motor is connected to the upper end of the rotating shaft. A tool holder is provided at the lower part of the rotating shaft, and a drill chuck is provided at the lower part of the tool holder. The upper part of the milling cutter is clamped and fixed by the drill chuck. When the drive motor is turned on, the drive motor drives the rotating shaft to rotate, which in turn drives the milling cutter to rotate, so that the rotating milling cutter contacts the guide sleeve. The groove is milled on the surface of the guide sleeve by the milling cutter, which facilitates the milling process of the guide sleeve.

[0010] Preferably, the lifting mechanism includes a hoisting frame, a hydraulic cylinder, a lifting rod, and a guide rod. The hydraulic cylinder is fixedly installed on the upper end of the hoisting frame, and the lifting rod and guide rod are both slidably installed on the hoisting frame. The power output end of the hydraulic cylinder is connected to the upper end of the lifting rod, and the linear cross slide module is fixedly installed on the lower end of the lifting rod and guide rod. The hoisting frame is fixedly hoisted on the support frame in the workshop. When adjusting the height of the milling cutter, the hydraulic cylinder is opened by an external controller, and the controller causes the hydraulic cylinder to drive the lifting rod to descend according to the pre-input machining program. This causes the lifting rod to drive the linear cross slide module, mounting plate, and fixed frame to descend, thereby causing the rotating shaft and milling cutter to descend to the specified height, and the guide sleeve is milled by the milling cutter.

[0011] Preferably, it also includes a linear module B, a movable block, a support, a rotating shaft, a three-jaw chuck B, and a three-jaw chuck C. The linear module B is fixedly mounted on the base plate. The movable block is provided on the linear module B and is used to move the movable block left and right. The support is fixedly mounted on the upper end of the movable block. Support plates A and B are respectively provided on the left and right sides of the upper end of the support. The rotating shaft is rotatably mounted on support plate A. The three-jaw chuck B is fixedly mounted on the right end of the rotating shaft. The three-jaw chuck C is fixedly mounted on support plate B and clamps and fixes the rotating shaft. The rotating shaft and the rotating block... The shafts are coaxial. With the above settings, when milling long shaft-type parts, the left side of the part is clamped and fixed by the three-jaw chuck A. Then, the linear module B is opened, causing the moving block to move to the left. This causes the support to drive the rotating shaft and the three-jaw chuck B to move to the left, so that the three-jaw chuck B contacts the right side of the part. By clamping and fixing the right side of the part with the three-jaw chuck B, the stability of the part during milling is improved. When turning long parts, the clamping of the rotating shaft by the three-jaw chuck C is released, allowing the part to rotate, reducing the shaking of the part during machining and improving the machining accuracy.

[0015] To facilitate understanding of this invention, a more complete description will be provided below with reference to the accompanying drawings. This invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this invention more thorough and complete.

[0016] Example 1 like Figures 1 to 7 The guide sleeve turning and milling composite equipment of this utility model includes a base plate 1, a support plate 2, a clamping mechanism, a turning mechanism, and a milling mechanism. The support plate 2 is fixedly installed on the left side of the upper end of the base plate 1. The clamping mechanism is installed on the support plate 2 and has the function of clamping and fixing. The turning mechanism is installed on the rear side of the upper end of the base plate 1 and has the function of turning. The milling mechanism is located above the clamping mechanism and has the function of milling. When processing the guide sleeve 30, the guide sleeve 30 is first clamped and fixed by the clamping mechanism. Then, the outer circle of the guide sleeve 30 is turned by the turning mechanism until the outer circle of the guide sleeve 30 is completed. Then, the groove is milled on the upper part of the guide sleeve 30 by the milling mechanism. It not only has the function of turning but also the function of milling, which reduces the transfer and secondary clamping of the workpiece during the processing, reduces the risk of the guide sleeve 30 being crushed during processing, reduces labor intensity, is convenient to use, and has high practicality.

[0017] like Figure 1The clamping mechanism includes a servo motor 3, a rotating shaft 4, and a three-jaw chuck A5. The servo motor 3 is fixedly mounted on the left end of the support plate 2, and the rotating shaft 4 is rotatably mounted on the support plate 2. The power output end of the servo motor 3 is connected to the left end of the rotating shaft 4, and the three-jaw chuck A5 is fixedly mounted on the right end of the rotating shaft 4. The servo motor 3 has an angle self-locking function. When clamping and fixing the guide sleeve 30, the left part of the guide sleeve 30 is clamped and fixed by the three-jaw chuck A5. Then, the servo motor 3 drives the rotating shaft 4 and the three-jaw chuck A5 to rotate, thereby causing the guide sleeve 30 to rotate at high speed. Then, the turning mechanism contacts the high-speed rotating guide sleeve 30, thereby causing the turning mechanism to turn the surface of the guide sleeve 30. After the turning of the guide sleeve 30 is completed, the servo motor 3 drives the rotating shaft 4 to stop rotating. At the same time, the servo motor 3 causes the rotating shaft 4 to self-lock at the angle, thereby fixing the three-jaw chuck A5 and the guide sleeve 30. Then, the milling mechanism mills the surface of the guide sleeve 30.

[0018] like Figure 1 and Figure 3 The turning mechanism includes a moving mechanism, a push plate 6, and a cutting tool 7. The cutting tool 7 is fixedly mounted on the front end of the push plate 6, and the push plate 6 is mounted on the moving mechanism. The moving mechanism is used to move the push plate 6. When it is necessary to turn the surface of the guide sleeve 30, the moving mechanism is opened, and the moving mechanism causes the push plate 6 to drive the cutting tool 7 to move, thereby moving the cutting tool 7 to contact the rotating guide sleeve 30, so that the cutting tool 7 can turn the surface of the guide sleeve 30. This facilitates the turning of the guide sleeve 30.

[0019] like Figure 3 The moving mechanism includes a linear module A8, a sliding plate 9, a vertical plate 10, a servo cylinder 11, a push rod 12, and a sliding rod 13. The linear module A8 is fixedly mounted on the base plate 1. The sliding plate 9 is mounted on the linear module A8 and is used to move the sliding plate 9 left and right. The vertical plate 10 is fixedly mounted on the upper end of the sliding plate 9. The servo cylinder 11 is fixedly mounted on the rear end of the vertical plate 10. The push rod 12 and the sliding rod 13 are both slidably mounted on the vertical plate 10. The power output end of the servo cylinder 11 is connected to the push rod 12. The push plate 6 is fixedly mounted on the push rod 13. The front ends of rod 12 and sliding rod 13; when turning the outer circle of guide sleeve 30, the servo electric cylinder 11 is turned on by an external controller, which in turn causes the servo electric cylinder 11 to drive the push rod 12 and push plate 6 to move forward, thereby causing the cutting tool 7 to contact the outer circle of guide sleeve 30. The cutting tool 7 turns the outer circle of the rotating guide sleeve 30. At the same time, the linear module A8 drives the sliding plate 9 to move in the left and right directions, which in turn causes the vertical plate 10 to drive the push rod 12, push plate 6 and cutting tool 7 to move in the left and right directions. During the left and right movement, the cutting tool 7 turns the left and right parts of the outer circle of guide sleeve 30.

[0020] like Figure 1 , Figure 4 and Figure 5The milling mechanism includes a lifting mechanism, a linear cross slide module 14, a mounting plate 15, and a milling device. The linear cross slide module 14 is mounted on the lifting mechanism, which is used to adjust the height of the linear cross slide module 14. The mounting plate 15 is provided on the linear cross slide module 14, and the linear cross slide module 14 is used to move the mounting plate 15 left and right and forward and backward. The milling device is installed at the lower end of the mounting plate 15 and has a milling function. After the outer circle of the guide sleeve 30 is machined, the servo motor 3 is self-locked at an angle, thereby fixing the rotating shaft 4 and the three-jaw chuck A5, and thus fixing the guide sleeve 30. The guide sleeve 30 is fixed in position. Then, the controller controls the lifting mechanism to lower the linear cross slide module 14 according to the pre-input processing program. This causes the mounting plate 15 to lower the milling device until it contacts the guide sleeve 30. The milling device then mills the surface of the guide sleeve 30. At the same time, the controller, according to the pre-input program, causes the linear cross slide module 14 to move the mounting plate 15 back and forth and left and right along the specified processing trajectory. This causes the milling device to move accordingly, so that the milling device can mill a groove on the surface of the guide sleeve 30. This facilitates the milling process of the guide sleeve 30.

[0021] The milling device includes a fixed frame 16, a drive motor 17, a rotating shaft 18, and a milling cutter 19. The fixed frame 16 is fixedly installed on the lower end of the mounting plate 15, the drive motor 17 is fixedly installed on the mounting plate 15, and the rotating shaft 18 is rotatably installed on the fixed frame 16. The power output end of the drive motor 17 is connected to the upper end of the rotating shaft 18. A tool holder is provided at the lower part of the rotating shaft 18, and a drill chuck is provided at the lower part of the tool holder. The upper part of the milling cutter 19 is clamped and fixed by the drill chuck. When the drive motor 17 is turned on, the drive motor 17 drives the rotating shaft 18 to rotate, which in turn drives the milling cutter 19 to rotate, so that the rotating milling cutter 19 contacts the guide sleeve 30. The groove is milled on the surface of the guide sleeve 30 by the milling cutter 19, which facilitates the milling process of the guide sleeve 30.

[0022] like Figure 4 The lifting mechanism includes a hoisting frame 20, a hydraulic cylinder 21, a lifting rod 22, and a guide rod 23. The hydraulic cylinder 21 is fixedly installed on the upper end of the hoisting frame 20. The lifting rod 22 and the guide rod 23 are both slidably installed on the hoisting frame 20. The power output end of the hydraulic cylinder 21 is connected to the upper end of the lifting rod 22. The linear cross slide module 14 is fixedly installed on the lower end of the lifting rod 22 and the guide rod 23. The hoisting frame 20 is fixedly hoisted on the support frame of the workshop. When the height of the milling cutter 19 is adjusted, the hydraulic cylinder 21 is opened by an external controller. The controller causes the hydraulic cylinder 21 to drive the lifting rod 22 to descend according to the pre-input processing program. The lifting rod 22 drives the linear cross slide module 14, the mounting plate 15, and the fixed frame 16 to descend, thereby causing the rotating shaft 18 and the milling cutter 19 to descend to the specified height. The guide sleeve 30 is milled by the milling cutter 19.

[0023] Example 2 Based on Example 1, such as Figure 6 It also includes a linear module B24, a moving block 25, a support 26, a rotating shaft 27, a three-jaw chuck B28, and a three-jaw chuck C29.

The rotating shaft 27 is rotatably mounted on support plate A. The three-jaw chuck B28 is fixedly mounted on the right end of the rotating shaft 27. The three-jaw chuck C29 is fixedly mounted on support plate B and clamps the rotating shaft 27. The rotating shaft 27 is fixed and coaxial with the rotating shaft 4. With the above settings, when milling a long shaft-type part, the left part of the part is clamped and fixed by the three-jaw chuck A5. Then, the linear module B24 is opened, and the moving block 25 moves to the left. This causes the support 26 to drive the rotating shaft 27 and the three-jaw chuck B28 to move to the left, so that the three-jaw chuck B28 contacts the right part of the part. By clamping and fixing the right part of the part with the three-jaw chuck B28, the stability of the part during milling is improved. When turning a long part, the clamping of the rotating shaft 27 by the three-jaw chuck C29 is released, allowing the part to rotate, reducing the shaking of the part during machining and improving the machining accuracy.

[0024] It should be noted that the electrical equipment in this case, such as servo motor 3, linear module A8, servo electric cylinder 11, linear cross slide module 14, drive motor 17 and linear module B24, are all connected to an external controller, which coordinates and controls the operation of each electrical device.
