Description

Technical Field

[0001] The present invention relates to the technical field of profile milling, in particular to a milling device for profile processing. Background Art

[0002] Milling is a common process in profile processing, widely used in industries such as construction, machinery manufacturing, and rail transit. Profiles are typically large, spanning several meters or even tens of meters. This makes positioning difficult, deformation prone, and precision difficult to achieve during processing. Traditional profile processing equipment typically utilizes fixed worktables or short-stroke clamping mechanisms, making them ill-suited for the continuous processing of long profiles. These often require multiple clamping or manual adjustments, resulting in low efficiency and the potential for repeatable positioning errors to compromise processing quality. While some existing milling equipment features multi-axis linkage, their clamping mechanisms are typically designed only for short profiles, making them incapable of stably supporting and conveying long profiles. Furthermore, the tool switching mechanisms of traditional equipment often rely on manual operation or simple tool changers. Frequent tool switching during processing of long profiles significantly reduces production efficiency. Furthermore, long profiles are prone to flexing and deformation due to their own weight or cutting forces during processing, and the support and clamping mechanisms of traditional equipment often lack adaptive adjustment capabilities, resulting in reduced processing precision. Therefore, there is an urgent need to develop a milling equipment specifically for long profile processing that can achieve stable clamping, automatic transportation, and efficient switching of multiple processes to meet the high-precision and continuous processing requirements of long profiles. Summary of the Invention

[0003] In response to the above technical problems, the present invention adopts a technical solution as follows: a milling device for processing profiles, comprising a frame mechanism; the frame mechanism comprises a base and an extension frame, and the frame mechanism is provided with a milling mechanism for milling the profiles and a clamping mechanism for clamping and conveying the profiles to be processed; The frame mechanism comprises a fixed plate fixedly mounted on the base, and a sliding plate is slidably mounted on the base.

[0004] Furthermore, the frame mechanism also includes a displacement motor and a sliding motor fixedly mounted on the base, a sliding screw and a displacement screw are rotatably mounted on the base, the displacement screw is fixedly mounted on the motor shaft of the displacement motor, the sliding screw is fixedly mounted on the motor shaft of the sliding motor, the sliding plate and the sliding screw form a threaded transmission, a movable seat is slidably mounted on the base, the movable seat and the displacement screw form a threaded transmission, a top motor is fixedly mounted on the movable seat, a lifting screw is rotatably mounted on the movable seat, the lifting screw is fixedly mounted on the motor shaft of the top motor, a lifting block is slidably mounted on the movable seat, the extension frame is slidably mounted on the lifting block, the lifting block and the lifting screw form a threaded transmission, the extension motor is fixedly mounted on the extension frame, the extension screw is rotatably mounted on the extension frame, the extension screw is fixedly mounted on the motor shaft of the extension motor, and the lifting block and the extension screw form a threaded transmission.

[0005] The sliding motor drives the sliding screw to rotate, driving the sliding plate to slide along the base; the displacement motor drives the displacement screw to rotate, driving the moving seat to slide along the base; the top motor drives the lifting screw to rotate, driving the lifting block to rise and fall along the moving seat; the extension motor drives the extension screw to rotate, driving the extension frame to slide relative to the lifting block.

[0006] Furthermore, the milling mechanism includes a connecting plate fixedly mounted on the extension frame, an inner motor fixedly mounted in the extension frame, a tool changer rotatably mounted on the motor shaft of the inner motor, and a driving bevel gear fixedly mounted on the motor shaft of the inner motor.

[0007] Furthermore, a milling cutter and two drill bits are rotatably mounted on the tool changer, a milling cutter bevel gear is fixedly mounted on the milling cutter, a drill bevel gear is fixedly mounted on the drill bit, the drill bevel gear is meshed with the active bevel gear, and the milling cutter bevel gear is meshed with the active bevel gear.

[0008] Furthermore, a switching disk is fixedly mounted on the tool changing seat, a switching motor is fixedly mounted on the connecting plate, a transmission wheel is fixedly mounted on the motor shaft of the switching motor, a transmission belt is wrapped around the transmission wheel and the switching disk, and three slots are provided on the switching disk.

[0009] Furthermore, a fixed frame is fixedly installed on the connecting plate, a magnetic block is slidably installed in the fixed frame, three card strips are fixedly installed on the magnetic block, and an electromagnet is fixedly installed on the connecting plate. The material of the magnetic block is magnetic material. In the initial state, the card strip is located in the card slot of the switching disk.

[0010] When performing milling processing, the internal motor drives the active bevel gear to rotate, which drives the milling cutter bevel gear and the milling cutter to rotate. In conjunction with the sliding of the extension frame relative to the lifting block, the lifting of the lifting block relative to the moving seat, and the sliding of the moving seat along the base, the profile is milled by the milling cutter. During the processing operation, the card strip is stuck in the switching disk, making it impossible for the tool changer to rotate with the internal motor.

[0011] When drilling is required, the electromagnet changes polarity and attracts the magnetic block, which slides inward along the fixed frame, causing the card strip to disengage from the card slot of the switching disk. At this time, the switching motor rotates, driving the switching disk and the tool changer to rotate 120 degrees through the transmission belt, so that the drill bit points downward. After the switching is completed, the electromagnet changes polarity and pushes the magnetic block outward, and the card strip is again inserted into the card slot of the switching disk. At this time, the profile can be drilled with the drill bit.

[0012] Furthermore, there are two clamping mechanisms, one located on the fixed plate and the other located on the sliding plate. The clamping mechanism includes a clamping seat, and the two clamping seats are fixedly installed on the fixed plate and the sliding plate respectively, and two clamping plates are slidably installed on the clamping seat.

[0013] Furthermore, the fixed plate and the sliding plate are respectively fixedly installed with an inner electric cylinder, the output end of the inner electric cylinder is fixedly installed with an inner slider, the two inner sliders are slidably installed with the fixed plate and the sliding plate, the sliding plate and the fixed plate are respectively fixedly installed with vertical blocks, the vertical blocks are slidably installed with a lifting seat, the lifting seat is fixedly installed with a conveying motor, the lifting seat is rotatably installed with a conveying roller and a lifting roller, the conveying motor drives the conveying roller to rotate through a belt drive, and a slope block is provided on the inner slider, and the slope block cooperates with the lifting roller.

[0014] Furthermore, a connecting column is fixedly installed on the inner slider, a slide plate is slidably installed under the clamping seat, the slide plate is fixedly installed on the connecting column, two connecting rods are rotatably installed on the slide plate, and the connecting rods are rotatably installed on the splint.

[0015] When in use, the profile is placed on the conveyor roller and the profile is located between the two clamping plates. When processing is carried out, the inner electric cylinder contracts, driving the inner slider and the slide plate to slide, and driving the two clamping plates to move inward through the connecting rod, and the profile is clamped by the clamping plates. At the same time, the slope block slides in the direction away from the jacking roller, and the lifting seat drops under the action of gravity, causing the conveyor roller to drop below the clamping seat. When the processing is completed and the profile needs to be conveyed, the inner electric cylinder extends, driving the inner slider and the slide plate to slide, and driving the two clamping plates to move outward through the connecting rod, so that the clamping plates release the clamping of the profile. At the same time, the slope block lifts the jacking roller and the lifting seat, causing the conveyor roller to rise, and the profile is lifted from the clamping seat by the conveyor roller. The conveying motor drives the conveyor roller to rotate through the belt drive, and the conveyor roller drives the profile to be conveyed, adjust the processing position of the profile or send the profile out.

[0016] Compared with the prior art, the present invention has the following advantages: (1) The present invention realizes continuous and automatic processing of long profiles through multi-axis linkage control of sliding motor, displacement motor, top motor and extension motor, combined with the automatic clamping and conveying function of the clamping mechanism, significantly improves production efficiency and reduces manual intervention; (2) The present invention adopts a switchable tool changer structure controlled by an electromagnet, combined with a switching motor drive, which can quickly and accurately switch between milling cutters and drill bits without manual tool change, meet complex processing requirements, and improve processing flexibility; (3) The clamping mechanism provided in the present invention adopts a bidirectional clamping design driven by an internal electric cylinder, combined with the linkage structure of the slope block and the lifting roller, which can not only firmly fix the long profile to prevent processing deformation, but also realize automatic lifting and conveying, ensure accurate adjustment of the processing position, and improve processing accuracy; (4) The present invention uses bidirectional displacement adjustment of the sliding plate and the moving seat, combined with the vertical movement of the lifting block, so that the milling mechanism can cover any processing position of the long profile, avoid positioning difficulties caused by the excessive length of the profile, and meet the processing requirements of large-sized workpieces.

[0033] like Figure 4-Figure 7 As shown, the milling mechanism includes a connecting plate 201 fixedly mounted on the extension frame 112, an inner motor 202 is fixedly mounted in the extension frame 112, a tool changer 203 is rotatably mounted on the motor shaft of the inner motor 202, and a driving bevel gear 210 is fixedly mounted on the motor shaft of the inner motor 202.

[0034] like Figure 4-Figure 7 As shown, a milling cutter 212 and two drill bits 211 are rotatably mounted on the tool changer 203 , a milling cutter bevel gear 214 is fixedly mounted on the milling cutter 212 , a drill bevel gear 213 is fixedly mounted on the drill bit 211 , the drill bevel gear 213 is meshed with the active bevel gear 210 , and the milling cutter bevel gear 214 is meshed with the active bevel gear 210 .

[0035] like Figure 4-Figure 7 As shown, a switching disk 205 is fixedly mounted on the tool changer 203, a switching motor 204 is fixedly mounted on the connecting plate 201, a transmission wheel is fixedly mounted on the motor shaft of the switching motor 204, a transmission belt is wrapped around the transmission wheel and the switching disk 205, and three slots are provided on the switching disk 205.

[0036] like Figure 4-Figure 7 As shown, a fixed frame 209 is fixedly installed on the connecting plate 201, a magnetic block 206 is slidably installed in the fixed frame 209, three clips 207 are fixedly installed on the magnetic block 206, and an electromagnet 208 is fixedly installed on the connecting plate 201. The material of the magnetic block 206 is magnetic material. In the initial state, the clip 207 is located in the slot of the switching disk 205.

[0037] When performing milling processing, the internal motor 202 drives the active bevel gear 210 to rotate, driving the milling cutter bevel gear 214 and the milling cutter 212 to rotate, cooperating with the sliding of the extension frame 112 relative to the lifting block 111, the lifting and lowering of the lifting block 111 relative to the moving seat 108, and the sliding of the moving seat 108 along the base 101, and the milling cutter 212 is used to mill the profile 4. During the processing operation, the card bar 207 is stuck in the switching disk 205, so that the tool change seat 203 cannot rotate with the internal motor 202.

[0038] When drilling is required, the electromagnet 208 changes its polarity and attracts the magnetic block 206. The magnetic block 206 slides inward along the fixed frame 209, so that the card strip 207 disengages from the card slot of the switching disk 205. At this time, the switching motor 204 rotates, and drives the switching disk 205 and the tool changer 203 to rotate one hundred and twenty degrees through the transmission belt, so that the drill bit 211 faces downward. After the switching is completed, the electromagnet 208 changes its polarity and pushes the magnetic block 206 outward. The card strip 207 is again inserted into the card slot of the switching disk 205. At this time, the profile 4 can be drilled by the drill bit 211.

[0039] like Figure 1 、 Figures 8-10 As shown, there are two clamping mechanisms, one located on the fixed plate 102 and the other located on the sliding plate 103. The clamping mechanism includes a clamping seat 301, and the two clamping seats 301 are fixedly installed on the fixed plate 102 and the sliding plate 103 respectively. Two clamping plates 307 are slidably installed on the clamping seat 301.

[0040] like Figure 1 、 Figures 8-10 As shown, the fixed plate 102 and the sliding plate 103 are respectively fixedly mounted with an inner electric cylinder 308, and the output end of the inner electric cylinder 308 is fixedly mounted with an inner slider 309, and the two inner sliders 309 are slidably mounted with the fixed plate 102 and the sliding plate 103, and the sliding plate 103 and the fixed plate 102 are respectively fixedly mounted with vertical blocks 302, and a lifting seat 303 is slidably mounted on the vertical block 302, and a conveying motor 304 is fixedly mounted on the lifting seat 303, and a conveying roller 305 and a lifting roller 306 are rotatably mounted on the lifting seat 303. The conveying motor 304 drives the conveying roller 305 to rotate through a belt drive, and a slope block 310 is provided on the inner slider 309, and the slope block 310 cooperates with the lifting roller 306.

[0041] like Figure 1 、 Figures 8-10 As shown, a connecting column 311 is fixedly installed on the inner slider 309, and a slide plate 312 is slidably installed under the clamping seat 301. The slide plate 312 is fixedly installed on the connecting column 311, and two connecting rods 313 are rotatably installed on the slide plate 312. The connecting rods 313 are rotatably installed on the clamping plate 307.

[0042] When in use, the profile 4 is placed on the conveying roller 305, and the profile 4 is located between the two clamping plates 307. When processing is carried out, the inner electric cylinder 308 contracts, driving the inner slider 309 and the slide plate 312 to slide, and the two clamping plates 307 are driven inward by the connecting rod 313 to clamp the profile 4 through the clamping plates 307. At the same time, the slope block 310 slides in the direction away from the lifting roller 306, and the lifting seat 303 descends under the action of gravity, causing the conveying roller 305 to descend below the clamping seat 301. When the processing is completed, the profile 4 needs to be conveyed. When the tool is moved, the inner electric cylinder 308 extends, driving the inner slider 309 and the slide plate 312 to slide, and the two clamping plates 307 are driven to move outward through the connecting rod 313, so that the clamping plates 307 release the clamping of the profile 4. At the same time, the slope block 310 lifts the lifting roller 306 and the lifting seat 303, so that the conveying roller 305 rises, and the profile 4 is lifted from the clamping seat 301 by the conveying roller 305. The conveying motor 304 drives the conveying roller 305 to rotate through the belt drive, and the conveying roller 305 drives the profile 4 to be conveyed, so as to adjust the processing position of the profile 4 or send the profile 4 out.

[0043] The working principle of the milling equipment for profile processing disclosed in the present invention is as follows: when in use, the profile 4 is placed on the conveying roller 305, and the profile 4 is located between the two clamping plates 307. When the processing operation is carried out, the inner electric cylinder 308 contracts, driving the inner slider 309 and the slide plate 312 to slide, and the two clamping plates 307 are driven inward by the connecting rod 313 to clamp the profile 4 through the clamping plates 307. At the same time, the slope block 310 slides in the direction away from the lifting roller 306, and the lifting seat 303 descends under the action of gravity. The conveying roller 305 drops below the clamping seat 301, and the sliding motor 104 drives the sliding screw 105 to rotate, driving the sliding plate 103 to slide along the base 101, and the displacement motor 106 drives the displacement screw 107 to rotate, driving the moving seat 108 to slide along the base 101, and the top motor 109 drives the lifting screw 110 to rotate, driving the lifting block 111 to rise and fall along the moving seat 108, and the extension motor 113 drives the extension screw 114 to rotate, driving the extension frame 112 to slide relative to the lifting block 111. When performing milling processing, the internal motor 202 drives the active bevel gear 210 to rotate, driving the milling cutter bevel gear 214 and the milling cutter 212 to rotate, cooperating with the sliding of the extension frame 112 relative to the lifting block 111, the lifting and lowering of the lifting block 111 relative to the moving seat 108, and the sliding of the moving seat 108 along the base 101, and the milling cutter 212 is used to mill the profile 4. During the processing operation, the card bar 207 is stuck in the switching disk 205, so that the tool change seat 203 cannot rotate with the internal motor 202. When drilling is required, the electromagnet 208 changes its polarity and attracts the magnetic block 206. The magnetic block 206 slides inward along the fixed frame 209, so that the card strip 207 disengages from the card slot of the switching disk 205. At this time, the switching motor 204 rotates, and drives the switching disk 205 and the tool changer 203 to rotate one hundred and twenty degrees through the transmission belt, so that the drill bit 211 faces downward. After the switching is completed, the electromagnet 208 changes its polarity and pushes the magnetic block 206 outward. The card strip 207 is again inserted into the card slot of the switching disk 205. At this time, the profile 4 can be drilled by the drill bit 211. When the processing is completed and the profile 4 needs to be transported, the inner electric cylinder 308 extends, driving the inner slider 309 and the slide plate 312 to slide, and drives the two clamps 307 to move outward through the connecting rod 313, so that the clamps 307 release the clamping of the profile 4. At the same time, the slope block 310 lifts the lifting roller 306 and the lifting seat 303, so that the conveying roller 305 rises, and the profile 4 is lifted from the clamping seat 301 by the conveying roller 305. The conveying motor 304 drives the conveying roller 305 to rotate through the belt drive, and the conveying roller 305 drives the profile 4 to be transported, adjusts the processing position of the profile 4 or sends the profile 4 out.

[0044] The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
