Description

Technical Field

[0001] This application relates to the field of machining and milling technology, and in particular to a guide edge machine. Background Technology

[0002] With the continuous development of the manufacturing industry, the requirements for processing accuracy and efficiency of various workpieces are increasing. In the field of machining, chamfering of quadrilateral workpieces is a common and important process. It not only improves the appearance quality of the workpiece but also enhances its performance and safety. Good chamfering can reduce stress concentration and prevent defects such as cracks from appearing during use, thereby improving product reliability and service life. The demand for chamfering of quadrilateral workpieces is widespread in many industries such as automobile manufacturing and electronic equipment.

[0003] In traditional machining methods, the chamfering of four sides of a quadrilateral workpiece is usually done manually. Workers use handheld tools such as files and grinding wheels to chamfer each side of the workpiece. While this method offers some flexibility, it is extremely inefficient and the machining accuracy is difficult to guarantee, easily affected by the worker's skill level and proficiency. Another common method is to use simple fixtures to hold the workpiece and then process it on a conventional machine tool. However, these fixtures have poor clamping stability, and the workpiece is prone to shifting during machining, resulting in inconsistent chamfer dimensions and affecting product quality. Moreover, the feed and steering control of conventional machine tools is not precise enough to achieve complex machining paths.

[0004] The existing manual operation method for chamfering the four sides of quadrilateral workpieces is inefficient and cannot meet the needs of large-scale production. On the other hand, the simple fixture and ordinary machine tool processing method has unstable clamping, makes it difficult to guarantee the processing accuracy, cannot achieve continuous cutting, and includes a large amount of idle stroke, resulting in low processing efficiency. Summary of the Invention

[0005] In order to improve the problems of low processing efficiency and difficulty in ensuring processing accuracy in manual operation, and the inability of CNC machine tools to achieve continuous cutting, which leads to reduced processing efficiency, this application provides a guiding edge machine.

[0006] The edge guiding machine provided in this application adopts the following technical solution: An edge guiding machine includes a base, a clamping mechanism, a machining mechanism, and a feeding mechanism. The base has a first positioning part and a second positioning part. The first positioning part is used to position and limit the two side walls of the workpiece. The clamping mechanism is disposed on the second positioning part and is used to clamp and limit the remaining two side walls of the workpiece. The machining mechanism is disposed on the top of the workpiece and is used to cut the chamfered surface of the workpiece. The feeding mechanism is disposed on one side of the first positioning part and is used to realize the machining reciprocating motion. The machining mechanism and the feeding mechanism cooperate to form a "U" shaped trajectory along the edge of the workpiece.

[0007] By adopting the above technical solution, the first positioning part on the base can position and limit the two side walls of the workpiece, determining the position of the workpiece in these two directions. The clamping mechanism is set in the second positioning part, which can press and limit the remaining two side walls of the workpiece, so that the workpiece is firmly fixed on the base, preventing movement or shaking during processing. The processing mechanism is set on the top of the workpiece and can perform cutting operations on the chamfered surface of the workpiece to complete the required chamfering processing. The feed mechanism is located on one side of the first positioning part and can realize the reciprocating motion during the processing, which is the key to the continuous processing. Under the mutual cooperation of the feed motion, the processing mechanism forms a "U" shaped trajectory along the edge of the workpiece, performing comprehensive and orderly chamfering processing on each edge of the workpiece according to the predetermined route, improving the processing accuracy and efficiency, and ensuring that each chamfered surface of the workpiece meets the processing requirements.

[0008] Optionally, the feeding mechanism includes a rotary support motor base mounted on the base, a driving component mounted on the rotary support motor base, a transmission component mounted on the driving component, and a movable component cooperating with the transmission component. The driving component drives the transmission component to rotate along its axis, and the movable component reciprocates in a direction parallel to the edge of the workpiece under the influence of the transmission component.

[0009] By adopting the above technical solution, the driving component serves as the power source, transmitting power to the transmission component. The moving component is acted upon by the transmission component, enabling the milling of the workpiece along a loop trajectory.

[0010] Optionally, the driving component includes a rotary support motor mounted on a rotary support motor base, and a fixed helical gear connected to the output end of the rotary support motor via a key.

[0011] By adopting the above technical solution, a rotating bracket motor is used as the power source, and the driving force is transmitted to the fixed helical gear through the cooperation of the fixed helical gear and the transmission component.

[0012] Optionally, the transmission component includes a double-ended helical gear meshing with a fixed helical gear, a first connecting rod mounted on the output shaft of a rotating support motor, and a second connecting rod hinged to the first connecting rod. The connecting ends of the second connecting rod and the first connecting rod are coaxially connected to a support helical gear. The support helical gear meshes with the double-ended helical gear. The diameter of the gear ring of the fixed helical gear is larger than the diameter of the double-ended helical gear, and the length of the second connecting rod is shorter than the length of the first connecting rod.

[0013] By adopting the above technical solution, after the fixed helical gear is driven to rotate, it will drive the double-headed helical gear meshing on it to rotate. The double-headed helical gear will generate its own rotation while revolving around the sun, driving the bracket helical gear meshing with it to rotate. Through the cooperation of connecting rod one and connecting rod two, reciprocating motion on a unidirectional axis is realized.

[0014] Optionally, the movable component includes a driven rod bracket arranged along the X-axis of the workpiece, a pad slidably arranged on the driven rod bracket, and a driven rod slidably arranged on the driven rod bracket along the Y-axis of the workpiece. The driven rod and the pad are fixed, and the pad and the end of the connecting rod away from the helical gear of the bracket are connected.

[0015] By adopting the above technical solution, using the driven rod support along the X-axis of the workpiece, the sliding pad, and the driven rod sliding along the Y-axis of the workpiece, with the driven rod fixed to the pad and the pad connected to the connecting rod, the rotational motion of the transmission component can be converted into the reciprocating motion of the moving component parallel to the edge of the workpiece. This, combined with the machining mechanism forming a "U" shaped trajectory along the edge of the workpiece, enables the cutting of the chamfered surface of the workpiece.

[0016] Optionally, the processing mechanism includes a rotary block motor base mounted on a base, a rotary block motor mounted on the rotary block motor base, a rotary block motor helical gear set mounted on the output end of the rotary block motor, a rotary block mounted on the rotary block motor helical gear set, and a steering rod slidably mounted on the rotary block. A steering spring is sleeved on the steering rod, and the end of the steering rod forms a bent portion for limiting the rotary block. One end of the steering spring is connected to the rotary block, and the other end of the steering spring is connected to the bent portion. A milling cutter seat is rotatably mounted on the bent portion, and the milling cutter seat and the driven rod are in sliding engagement.

[0017] By adopting the above technical solution, a rotary block motor is used as the output power source. The rotary block and the steering rod are driven to move by the meshing of the rotary block helical gear set of the rotary block motor. The steering rod rotates around the rotary block as a reference point. During the rotation, the position change of the milling cutter holder on the steering rod is further controlled by the steering spring. At the same time, the driven rod and the driven rod support limit the movement of the driven rod, so that the milling cutter holder moves in a loop trajectory.

[0018] Optionally, the clamping mechanism includes an eccentric wheel push rod, a clamping plate, a handle, and an elastic element. The eccentric wheel push rod has an arc-shaped portion and a flat portion. The clamping plate abuts against the arc-shaped portion, and the handle is mounted on the flat portion. The side of the clamping plate away from the arc-shaped portion abuts against the side wall of the workpiece. A through groove is provided on the clamping plate. The clamping plate and the base are restricted to move in the Z-axis direction by a positioning screw. The end of the elastic element is connected to the positioning screw and the eccentric wheel push rod, respectively. When the handle is rotated counterclockwise, the eccentric wheel push rod rotates counterclockwise with the handle, and the clamping plate moves toward the eccentric wheel push rod. The clamping plate is at its first limit position, and the clamping plate and the workpiece remain disengaged. When the handle is rotated clockwise, the eccentric wheel push rod abuts against the clamping plate, and the clamping plate is at its second limit position, and the clamping plate and the workpiece remain in close contact.

[0019] By adopting the above technical solution, the eccentric wheel push rod is manually tightened as the clamping power source. The eccentric wheel push rod rotates clockwise around the positioning screw, and the arc-shaped part presses against the clamping plate to achieve reliable fixation of the workpiece. Through the self-locking effect and eccentric clamping action generated by the eccentric wheel push rod mechanism during tightening, the clamping plate clamps the workpiece in one direction. The structure is simple and reliable, and the clamping force is stable. Conversely, when the eccentric wheel push rod rotates counterclockwise, the arc-shaped part and the clamping plate are released, so that the workpiece is positioned and released. The clamping plate can be moved between the first and second limit positions by rotating the handle, which facilitates the clamping and unloading of the workpiece.

[0020] Optionally, the second positioning part includes a positioning hole on the base, positioning pin holes on both sides of the base clamp, a positioning screw mounted on the eccentric wheel push rod, and a positioning nut locked on the positioning screw. The positioning screw passes through the positioning nut, the eccentric wheel push rod, and the positioning hole in sequence for threaded engagement.

[0021] By adopting the above technical solution, the eccentric wheel push rod is positioned through the center of the positioning hole by the positioning screw and tightened with the positioning nut, thereby realizing the connection and positioning of the eccentric wheel push rod and the base, ensuring that the eccentric wheel push rod rotates along the axis of the positioning screw, and the positioning pin holes on both sides of the clamp plate play a certain limiting role for the clamp plate.

[0022] Optionally, the elastic element is any one of a tension spring, a rubber band, and an elastic band.

[0023] By adopting the above technical solution, an elastic element is selected to ensure that the clamping plate and the eccentric wheel push rod maintain traction, so that the clamping plate and the eccentric wheel push rod always remain in close contact.

[0024] Optionally, the spacing between adjacent positioning pin holes on the second positioning part is greater than the width of the clamping plate, and the center line of the through groove coincides with the diagonal of the workpiece being processed.

[0025] By adopting the above technical solution, the distance between adjacent positioning pin holes is greater than the width of the clamping plate, which can ensure that the clamping plate can be smoothly installed and moved between the positioning pins. The center line of the through groove coincides with the diagonal line of the workpiece, which can accurately position the workpiece. This allows the clamping mechanism to better cooperate in clamping the workpiece stably, so that the workpiece is accurately positioned in the corresponding position. This is beneficial for the subsequent processing mechanism and the feed mechanism to form a "U" shaped trajectory along the edge of the workpiece to cut the chamfered surface of the workpiece.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The clamping power source is the manually tightened eccentric wheel push rod. The eccentric wheel push rod rotates around the positioning screw and presses the clamping plate. The self-locking effect and eccentric pressing action of the eccentric wheel push rod mechanism when tightening make the clamping plate press the workpiece in one direction, so as to achieve reliable fixation of the workpiece being processed. The structure is simple and reliable and the clamping force is stable. 2. Using a rotary support motor as the power source, the rotational motion is converted into a precise vertical reciprocating motion along the driven rod support through the meshing relationship between the fixed helical gear and the double-headed helical gear. The motion is then transmitted to the milling cutter through the driven rod, thereby realizing the axial feed of the milling process and improving the machining accuracy. 3. Using a rotary block motor as the steering power source, the rotation of the rotary block and the steering rod is driven by the meshing of the rotary block motor helical gear and the rotary block helical gear, thereby controlling the deflection of the milling cutter. The steering spring provides elastic reset for the steering process, which can accurately control the working angle of the milling cutter and realize complex machining paths.

[0037] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0038] This application discloses an edge guiding machine device.

[0039] Reference Figure 1 and Figure 2 As shown, the device includes a base 1, a clamping mechanism 2, a machining mechanism 3, and a feed mechanism 4. The base 1 provides a supporting foundation for the entire device and has a first positioning part 11 and a second positioning part 12. The two positioning parts respectively position and restrict the four sides of the workpiece being processed. The first positioning part is specifically positioned by a pin, with the side of the workpiece abutting against the pin. The clamping mechanism 2 is used to securely fix the workpiece. The machining mechanism 3 is responsible for cutting the chamfered surface of the workpiece. The feed mechanism 4 realizes the reciprocating motion of the machining. The machining mechanism 3 and the feed mechanism 4 work together to form a "U" shaped trajectory along the edge of the workpiece, comprehensively and accurately chamfering the four sides of the quadrilateral workpiece, improving machining accuracy and efficiency, and meeting the requirements of modern industry for high-precision products.

[0040] See Figure 4As shown, the clamping mechanism 2 includes an eccentric wheel push rod 21, a clamping plate 22, a handle 23, and an elastic element 24. The eccentric wheel push rod 21 has an arc-shaped portion 211 and a flat portion 212. The clamping plate 22 abuts against the arc-shaped portion 211. The height of the clamping plate is less than the height of the workpiece being processed to prevent interference between the four sides of the workpiece during milling and chamfering. The eccentric wheel push rod 21 has a unique shape design. The arc-shaped portion 211 can have good contact and force transmission with the clamping plate 22. The flat portion 212 provides a suitable installation position for the handle 23. The handle 23 is installed on the flat portion 212 for easy manual operation by the operator. A hole is opened at the end of the handle away from the eccentric wheel push rod (not shown in the figure). This hole can be fixed by pins and base to ensure the stability of the clamping plate and the eccentric wheel push rod. The side of the clamping plate 22 away from the arc-shaped part 211 abuts against the side wall of the workpiece. A through groove 221 is provided on the clamping plate 22. The through groove 221 is waist-shaped. The clamping plate 22 and the base 1 are restricted to their Z-axis movement pair by the positioning screw 25. One end of the elastic element 24 is connected to the positioning screw 25, and the other end of the elastic element 24 is connected to the eccentric wheel push rod 21. The elastic element 24 can be a tension spring, rubber band, or elastic band. The tension spring has a high elastic coefficient and stability and can accurately provide elastic tension. The rubber band is relatively soft and low in cost, and is suitable for some scenarios where the elasticity requirement is not particularly high. The elastic band is highly adjustable and can adapt to different installation spaces and tension requirements. When handle 23 rotates counterclockwise, eccentric wheel push rod 21 rotates counterclockwise with handle 23, and clamping plate 22 moves toward eccentric wheel push rod 21. At this time, clamping plate 22 is in extreme position one, and clamping plate 22 and workpiece remain detached, facilitating the insertion or removal of workpiece. When handle 23 rotates clockwise, eccentric wheel push rod 21 abuts against clamping plate 22, and clamping plate 22 is in extreme position two, and clamping plate 22 and workpiece remain in close contact, achieving reliable clamping of workpiece. The clamping mechanism 2 generates a self-locking effect and eccentric pressing action through the rotation of eccentric wheel push rod 21, making clamping plate 22 firmly press the workpiece. The structure is simple yet stable and reliable, with stable clamping force.

[0041] See Figure 5 and Figure 8As shown, the second positioning part 12 corresponding to the clamping mechanism 2 includes a positioning hole 121 on the base 1, positioning pin holes 122 on both sides of the clamping plate 22 on the base 1, a positioning screw 123 mounted on the eccentric wheel push rod 21, and a positioning nut 124 locked on the positioning screw 123. The positioning screw 123 passes through the positioning nut 124, the eccentric wheel push rod 21 and the positioning hole 121 in sequence, and is threaded to reliably install the eccentric wheel push rod 21 on the base 1. The position and angle of the eccentric wheel push rod 21 can be adjusted by the cooperation of the positioning screw 123 and the positioning nut 124. The distance between adjacent positioning pin holes 122 on the second positioning part 12 is greater than the width of the clamping plate 22. The center line of the through groove 221 coincides with the diagonal of the workpiece, which is conducive to accurately positioning the workpiece and ensuring that the workpiece is in the correct position when clamped, thereby improving the machining accuracy.

[0042] See Figure 5 and Figure 7 As shown, the feed mechanism 4 includes a rotary support motor base 41 mounted on the base 1, a drive member 42 mounted on the rotary support motor base 41, a transmission member 43 mounted on the drive member 42, and a movable member 44 that cooperates with the transmission member 43. The drive member 42 drives the transmission member 43 to rotate along its axis, and the movable member 44 is subjected to reciprocating motion parallel to the edge of the workpiece by the transmission member 43, thereby converting the rotational motion of the drive member 42 into the linear reciprocating motion of the movable member 44, providing precise power for the feed of the processing mechanism 3.

[0043] See Figure 7 As shown, the drive unit 42 includes a rotary support motor 421 mounted on a rotary support motor base 41, and a fixed helical gear 422 connected to the output end of the rotary support motor 421 via a key. The rotary support motor 421 provides rotational power, and the key connection ensures accurate and reliable torque transmission between the fixed helical gear 422 and the output end of the rotary support motor 421. The fixed helical gear 422, as a key component of the drive unit 42, provides a stable rotational foundation for subsequent transmission.

[0044] See Figure 7As shown, the transmission component 43 includes a double-ended helical gear 431 meshing with a fixed helical gear 422, a connecting rod 432 mounted on the output shaft of the rotating support motor 421, and a connecting rod 433 hinged to the connecting rod 432. The rotation angle range of the connecting rods 432 and 433 is less than the distance between the driven rod support 441 and the base 1 to avoid mutual interference. The connecting ends of the connecting rod 433 and the connecting rod 432 are coaxially connected to a support helical gear 434, which meshes with the double-ended helical gear 431. The diameter of the gear ring of the fixed helical gear 422 is larger than the diameter of the double-ended helical gear 431, and the length of the connecting rod 433 is less than the length of the connecting rod 432. When the fixed helical gear 422 rotates, the double-headed helical gear 431 meshing with it will rotate on its own axis while revolving around the revolution. This compound motion is transmitted to the support helical gear 434 through connecting rod 1 432 and connecting rod 2 433, which in turn drives the support helical gear 434 to rotate. The different diameter and length designs enable the transmission component 43 to realize the functions of speed change and reversal to meet the different motion requirements of the moving component 44.

[0045] See Figure 7 As shown, the movable component 44 includes a driven rod support 441 arranged along the X-axis of the workpiece, a pad 442 slidably arranged on the driven rod support 441, and a driven rod 443 slidably arranged on the driven rod support 441 along the Y-axis of the workpiece. The driven rod 443 and the pad 442 are fixed together, and the pad 442 is connected to the end of the connecting rod 433 away from the helical gear 434 of the support. When the transmission component 43 drives the pad 442 to move, since the pad 442 is fixedly connected to the driven rod 443 and the pad 442 slides on the driven rod support 441, the driven rod 443 will correspondingly make a linear reciprocating motion along the edge of the workpiece, thereby driving the machining mechanism 3 to achieve a precise feed action.

[0046] See Figure 3 and Figure 6As shown, the machining mechanism 3 includes a rotary block motor base 31 mounted on the base 1, a rotary block motor 32 mounted on the rotary block motor base 31, a rotary block motor helical gear set 33 mounted on the output end of the rotary block motor 32, a rotary block 34 mounted on the rotary block motor helical gear set 33, and a steering rod 35 slidably mounted on the rotary block 34. A steering spring 36 is sleeved on the steering rod 35, and the end of the steering rod 35 forms a bent portion for limiting the rotary block 34. One end of the steering spring 36 is connected to the rotary block 34, and the other end of the steering spring 36 is connected to the bent portion. A milling cutter holder 37 is rotatably mounted on the bent portion, and the milling cutter holder 37 and the driven rod 443 are in sliding engagement. After the rotary block motor 32 is started, it drives the rotary block motor helical gear set 33 to rotate, which in turn drives the rotary block 34 to rotate around its axis. The rotation of the rotary block 34 causes the steering rod 35 and the milling cutter connected to it to change their working angle. The steering spring 36 provides the necessary elastic restoring force for the steering movement, ensuring that the milling cutter can accurately return to its initial position or be positioned to the next machining angle after steering. The milling cutter on the milling cutter holder 37 adjusts its angle under the control of the steering rod 35. At the same time, the linear reciprocating motion of the driven rod 443 is transmitted to the milling cutter through the milling cutter holder 37 to realize the axial feed of the milling operation, thereby completing the cutting of the chamfered surface of the workpiece.

[0047] The implementation principle of the edge guiding machine according to this application embodiment is as follows: The workpiece is placed on the clamping plate 22 and positioned by the first positioning part 11 on both sides of the workpiece. The first positioning part 11 is usually limited by pins on both sides to complete the initial positioning. The handle 23 of the eccentric wheel push rod 21 is pushed counterclockwise to drive the eccentric wheel push rod 21 to rotate around the axis of its positioning screw 25, pressing the clamping plate 22 to the lower left, thereby stabilizing and fixing the workpiece. Next, the rotating bracket motor 421 is started, driving the rotating bracket motor 421 to rotate around its motor shaft. The fixed helical gear 422 fixed on the base 1 meshes with one end of the double-headed helical gear 431, forcing the double-headed helical gear 431 to rotate on its own axis while revolving around the center. This rotational motion is transmitted to the bracket helical gear 434 at the other end, driving it to rotate. The end of the helical gear 434 drives the pad 442 to move. Since the inner hole of the pad 442 is engaged with the fixed driven rod bracket 441, the rotational motion is converted into the reciprocating motion of the pad 442 along the driven rod bracket 441. During machining, the rotary block motor 32 is started, driving the helical gear of the rotary block 34 to rotate, which in turn meshes and drives the helical gear of the rotary block 34 to rotate. The helical gear of the rotary block 34 drives the rotary block 34 to rotate around its axis, thereby driving the steering rod 35 and the milling cutter connected to it to change the working angle. The steering spring 36 provides steering. The movement provides the necessary elastic restoring force. The milling cutter adjusts its angle under the control of the steering rod 35. Simultaneously, the movement of the pad 442 is transmitted to the milling cutter through the driven rod 443, realizing the axial feed of the milling operation. The driven rod 443, the pad 442, and the milling cutter holder 37 follow a "U"-shaped motion trajectory. During this trajectory, the on / off states of the rotary support motor 421 and the rotary block motor 32 are adjusted according to the position of the motion trajectory. The trajectory forms a movement sequentially along the positive X-axis → negative Y-axis → negative X-axis → positive Y-axis. During the positive X-axis movement, the steering rod 35... The steering spring 36 on the 5th rod is first compressed and then relaxed. The distance between the bent portions of the rotating block 34 and the steering rod 35 gradually decreases and then gradually increases. The driven rod 443 slides from one end of the driven rod support 441 to the other end. The milling cutter holder 37 is always located at one end of the driven rod 443. When moving towards the negative Y-axis, the driven rod 443 is always located at one end of the driven rod support 441. The milling cutter holder 37 moves along the driven rod 443 in sequence. Similarly, the distance between the bent portions of the rotating block 34 and the steering rod 35 gradually decreases and then gradually increases. When moving towards the negative X-axis... During movement, the driven rod 443 moves in the opposite direction along the driven rod support 441, while the bends of the rotating block 34 and the steering rod 35 gradually decrease and then increase in distance. When moving towards the positive Y-axis, the driven rod 443 remains in the same position on the driven rod support 441, while the bends of the rotating block 34 and the steering rod 35 gradually decrease and then increase in distance. After processing, the rotating block motor 32 and the rotating support motor 421 are stopped first, and the eccentric wheel push rod 21 rotates in the opposite direction, releasing the clamping force on the clamping plate 22, allowing the workpiece to be removed. Through the coordinated work of the clamping mechanism 2, the feed mechanism 4, and the processing mechanism 3, high-precision and high-efficiency processing of the chamfered edges of the quadrilateral workpiece is achieved.The clamping mechanism 2 utilizes the special structure and self-locking effect of the eccentric wheel push rod 21 to stably fix the workpiece and prevent workpiece displacement during processing; the feed mechanism 4 converts rotary motion into precise linear reciprocating motion through multi-stage transmission, providing reliable feed power for processing; the machining mechanism 3 can flexibly adjust the angle of the milling cutter and realize axial feed, accurately cutting the chamfered surface of the workpiece, greatly improving product quality and production efficiency, and meeting the requirements of modern industrial large-scale production and high-precision products.
