Description

Technical Field

[0001] This invention relates to the field of locking slide technology, specifically to the locking slide structure of cutting tools in milling and turning composite equipment. Background Technology

[0002] Milling-turning composite equipment is a composite device in the prior art used to combine CNC turning and milling machining modes in the process of machining a workpiece. It is used to perform continuous turning and milling machining on a specific workpiece, improving the continuity of workpiece machining. In the use of milling-turning composite equipment, the cutting tools and tool drive devices used for milling the workpiece are installed through a locking ram structure. The locking ram structure can also enable precise longitudinal movement of the cutting tools and tool drive devices. The ram structure generally uses a lead screw transmission mechanism to move the tool drive device sliding on the ram. However, in the prior art, the locking ram uses a mechanical structure to lock the tool drive device after the lead screw transmission mechanism stops moving the tool drive device.

[0003] During the process of mounting the corresponding tool on the tool drive device and when the tool drive device switches between multiple tools, due to the differences in the shape of different tools and the machining position of the workpiece, the position of the tool drive device needs to be adjusted after changing the tool. This results in the tool drive device moving a large range on the slide structure. When the tool drive device moves a large range, the existing slide structure needs to perform a comprehensive locking operation on the sliding area of ​​the tool drive device, rather than a targeted locking operation on the stopping position of the tool drive device. This working method makes it difficult to perform targeted locking operations on different positions of the tool drive device on the slide structure. This not only easily leads to the problem of the tool drive device not being locked securely, but also affects the positioning problem during the use of the tool drive device. Summary of the Invention

[0004] This invention proposes a tool locking slide structure for milling and turning composite equipment, which solves the problems in the prior art where the tool drive device is easily not locked securely during the sliding process within the slide structure, and the positioning of the tool drive device's movement position is uncertain.

[0005] The technical solution of the present invention is as follows: a tool locking ram structure for a milling and turning composite equipment, including a ram frame, a lead screw transmission structure provided on one side inside the ram frame, a tool drive device longitudinally slidably disposed within the ram frame, and sliding seats slidably connected to both sides inside the ram frame, one of the sliding seats cooperating with the lead screw transmission structure, and further comprising:

[0006] The positioning blocks are provided in multiple groups of two. A flipping offset component is provided in the slide frame to drive the multiple positioning blocks to offset. A meshing positioning component is provided between the corresponding multiple positioning blocks and the sliding seat on the same side. The meshing positioning component is used to lock the tool drive device and to position the tool drive device.

[0007] The lifting clamping slots are provided on both sides of the slide frame. The tool driving device is slidably disposed between the two lifting clamping slots. A clamping and locking mechanism is provided between the tool driving device and the two lifting clamping slots.

[0008] To further adjust the positions of multiple positioning blocks, the flipping offset assembly includes a rotating cylinder and a gearbox. The rotating cylinder is rotatably mounted inside the ram frame. An elastic compensation structure is provided between the rotating cylinder and the inner bottom wall of the ram frame. Multiple mounting rings are fixedly sleeved on the rotating cylinder, and the positioning blocks are fixedly connected to the mounting rings. A rotating bushing is slidably sleeved on the top of the rotating cylinder, and a gearbox is driven on the rotating bushing. A drive motor is provided on the top of the ram frame, and the output end of the drive motor is driven by the gearbox.

[0009] To facilitate smooth engagement between the positioning block and the sliding seat, the elastic compensation structure further includes a support ring and a spring damper. The support ring is fixedly connected to the inner bottom wall of the ram frame. An annular inner groove is formed on the support ring. The bottom of the rotating cylinder extends into the annular inner groove, and the bottom of the rotating cylinder rotatably engages with the inner side wall of the annular inner groove. The bottom of the rotating cylinder moves longitudinally within the annular inner groove. The spring damper is located at the top of the support ring and is situated within the rotating cylinder. A partition plate is fixedly connected to the inner wall of the rotating cylinder, and the top of the spring damper is rotatably connected to the partition plate.

[0010] To further position the tool drive device, a sensing ring is provided on the top of the rotating cylinder, and a distance measuring sensor is provided on the upper side of the sensing ring.

[0011] To enable the positioning block to engage with the sliding seat, the engagement positioning assembly further includes an engagement clamp and a V-shaped elastic clamp. Multiple engagement clamps are arranged longitudinally on both inner walls of the sliding seat. The engagement clamps are fixedly connected inside the sliding seat. The inner wall of the engagement clamp is V-shaped. The positioning block is wedge-shaped, and both the upper and lower sides of the positioning block are inclined. The engagement clamp contains a V-shaped elastic clamp that is compatible with the positioning block.

[0012] To improve the stability of the lifting and lowering of the tool drive device, a lifting slide groove is further provided on the outer wall of the lifting clamping groove, and a sliding member is slidably connected to the lifting slide groove, and the sliding member is fixedly connected to the tool drive device.

[0013] To further lock the tool drive device, the inner wall of the lifting clamping groove is provided with a mounting protrusion, and the mounting protrusion is provided with a friction surface.

[0014] To cooperate with the friction surface and lock the tool drive device, the clamping and locking mechanism further includes a sliding groove and a lifting and pressing assembly. The sliding groove is laterally slidably connected in the lifting and pressing groove, and a connecting plate is longitudinally slidably connected in the sliding groove. The connecting plate is laterally slidably connected to the tool drive device. A friction groove is provided on the side of the connecting plate near the friction surface, and the friction groove cooperates with the friction surface. The lifting and pressing assembly for driving the connecting plate to move is provided between the tops of the two lifting and pressing grooves.

[0015] To further reset the sliding groove, a spring damper is provided between the sliding groove and the inner wall of the lifting clamping groove.

[0016] To further facilitate the lateral movement of the connecting plate, the lifting and pressing assembly includes a U-shaped insertion frame and a driving electric cylinder. The bottom of the U-shaped insertion frame is slidably connected through the lifting clamping groove. The bottom of the U-shaped insertion frame is a wedge-shaped surface, and the middle part of the connecting plate is a sloped surface. The wedge-shaped surface and the sloped surface cooperate with each other. The driving electric cylinder is mounted on the slide frame, and the output end of the driving electric cylinder is fixedly connected to the inner bottom of the U-shaped insertion frame.

[0017] The working principle and beneficial effects of this invention are as follows:

[0018] 1. In this invention, after the movement of the tool drive device stops, a flip offset component is used to drive multiple positioning blocks to rotate. The positioning block corresponding to the installation height of the meshing clamp will enter the corresponding meshing clamp after the rotating cylinder rotates. Through the full contact between the positioning block and the inner wall of the V-shaped elastic clamp, the tool drive device is locked. Furthermore, by determining the position of the positioning block in the meshing clamp and the height change after the rotating cylinder is raised by the spring damper, the specific position of the positioning tool drive device after it stops is accurately measured, which facilitates subsequent tool setting operations.

[0019] 2. In this invention, after the tool driving device stops moving, the lifting and pressing assembly drives the connecting plate to move laterally in the lifting clamping groove, so that the friction groove fits with the friction surface, and the connecting plate is clamped between the inner wall of the lifting clamping groove and the U-shaped insertion frame, further locking the tool driving device.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 11 As shown, this embodiment proposes a tool locking slide structure for a milling and turning composite equipment, including a slide frame 1. A lead screw transmission structure 2 is provided on one side inside the slide frame 1. The tool driving device 3 is longitudinally slidably disposed inside the slide frame 1. Sliding seats 4 are slidably connected to both sides inside the slide frame 1. One of the sliding seats 4 cooperates with the lead screw transmission structure 2. The slide frame 1 is laterally moved on the machining table of the milling and turning composite equipment. After the milling and turning composite equipment clamps the workpiece, it drives the slide frame 1 to move on the machining table. Through the lead screw transmission structure 2, the position of the tool driving device 3 is adjusted so that the workpiece contacts the milling and turning tool, thus completing the milling and turning operation on the workpiece.

[0035] It also includes positioning blocks 5, with multiple positioning blocks 5 arranged in pairs. A flip-off offset assembly is installed inside the ram frame 1 to drive the multiple positioning blocks 5 to shift. The flip-off offset assembly includes a rotating cylinder 7 and a gearbox 8. The rotating cylinder 7 is rotatably mounted inside the ram frame 1. An elastic compensation structure is provided between the rotating cylinder 7 and the inner bottom wall of the ram frame 1. Multiple mounting rings are fixedly sleeved on the rotating cylinder 7, and the positioning blocks 5 are fixedly connected to the mounting rings. A rotating shaft sleeve 9 is slidably sleeved on the top of the rotating cylinder 7. The upper sleeve 9 is equipped with a gearbox 8, and the top of the slide frame 1 is equipped with a drive motor 10. The output end of the drive motor 10 is connected to the gearbox 8 for transmission. After the tool drive device 3 moves longitudinally in the slide frame 1, the two sliding seats 4 move longitudinally together in the slide frame 1. After the tool drive device 3 stops moving, the drive motor 10 is started, and the gearbox 8 drives the rotating shaft sleeve 9 and the rotating cylinder 7 to rotate, which drives the positioning block 5 to shift along the center point of the rotating cylinder 7, so that the positioning block 5 can enter the meshing clamp 16.

[0036] The elastic compensation structure includes a support ring sleeve 11 and a spring damper 12. The support ring sleeve 11 is fixedly connected to the inner bottom wall of the slide frame 1. An annular inner groove is formed on the support ring sleeve 11. The bottom of the rotating cylinder 7 extends into the annular inner groove, and the bottom of the rotating cylinder 7 is rotatably engaged with the inner side wall of the annular inner groove. The bottom of the rotating cylinder 7 moves longitudinally within the annular inner groove. The spring damper 12 is provided at the top of the support ring sleeve 11 and is located inside the rotating cylinder 7. A partition is fixedly connected to the inner wall of the rotating cylinder 7. Plate 13, the top of spring damper 12 is rotatably connected to partition plate 13. When there is a slight mismatch between the position of positioning block 5 and engagement clamp 16, in order to allow positioning block 5 to enter engagement clamp 16, after positioning block 5 contacts V-shaped elastic clamp 17, spring damper 12 adaptively drives rotating cylinder 7 to move up or down. Rotating cylinder 7 is slidably connected to rotating bushing 9. The annular inner groove reserves the internal area for longitudinal movement of rotating cylinder 7, so that positioning block 5 enters the corresponding engagement clamp 16.

[0037] A sensing ring 14 is provided on the top of the rotating cylinder 7, and a distance sensor 15 is provided on the upper side of the sensing ring 14. The distance sensor 15 is set on the slide frame 1. In order to locate the position of the tool drive device 3 after it stops moving, first determine which positioning block 5 is in the meshing clamp 16, determine the horizontal height of the tool drive device 3, and accurately measure the specific position of the tool drive device 3 after it stops by the height change after the rotating cylinder 7 is raised by the spring damper 12.

[0038] Among them, a meshing positioning assembly is provided between the corresponding multiple positioning blocks 5 and the sliding seat 4 located on the same side. The meshing positioning assembly is used to lock the tool driving device 3 and to position the tool driving device 3. The meshing positioning assembly includes a meshing clamp seat 16 and a V-shaped elastic clamp 17. Multiple meshing clamp seats 16 are arranged longitudinally on both sides of the inner wall of the sliding seat 4. The meshing clamp seats 16 are fixedly connected in the sliding seat 4. The inner wall of the meshing clamp seat 16 is V-shaped, the positioning block 5 is wedge-shaped, and both the upper and lower sides of the positioning block 5 are inclined. A V-shaped elastic clamp 17 adapted to the positioning block 5 is provided in the meshing clamp seat 16. After the positioning block 5 enters the V-shaped elastic clamp 17, the tool driving device 3 is locked by the tight fit between the positioning block 5 and the inner wall of the V-shaped elastic clamp 17.

[0039] Lifting clamping slots 6 are provided on both sides of the slide frame 1. The tool drive device 3 is slidably disposed between the two lifting clamping slots 6. A lifting slide groove is provided on the outer wall of the lifting clamping slot 6. A sliding member 18 is slidably connected to the lifting slide groove. The sliding member 18 is fixedly connected to the tool drive device 3. In order to improve the lifting stability of the tool drive device 3, the middle part of the tool drive device 3 slides on the lifting slide groove through the sliding member 18.

[0040] The inner wall of the lifting clamping groove 6 is provided with a mounting protrusion 19, and a friction surface 20 is provided on the mounting protrusion 19. A clamping and locking mechanism is provided between the tool driving device 3 and the two lifting clamping grooves 6. The clamping and locking mechanism includes a sliding groove 21 and a lifting and pressing assembly. The sliding groove 21 is laterally slidably connected in the lifting clamping groove 6. A connecting plate 22 is longitudinally slidably connected in the sliding groove 21. The connecting plate 22 is laterally slidably connected to the tool driving device 3. A friction groove 23 is provided on the side of the connecting plate 22 near the friction surface 20. The friction groove 23 cooperates with the friction surface 20. A lifting and pressing assembly for moving the connecting plate 22 is provided between the tops of the two lifting clamping slots 6. When it is necessary to lock the tool drive device 3, the lifting and pressing assembly drives the connecting plate 22, which has been moved to the corresponding position, to move laterally, so that the friction groove 23 on the connecting plate 22 contacts the friction surface 20 in the lifting clamping slot 6, so that the mounting protrusion 19 enters the range of the friction groove 23, fixes the connecting plate 22, and further locks the tool drive device 3.

[0041] A spring damper 24 is provided between the sliding groove 21 and the inner wall of the lifting clamping groove 6. The lifting and pressing assembly includes a U-shaped insertion frame 25 and a drive electric cylinder 26. The bottom of the U-shaped insertion frame 25 is slidably connected through the lifting clamping groove 6. The bottom of the U-shaped insertion frame 25 is a wedge-shaped surface, and the middle part of the connecting plate 22 is a sloped surface. The wedge-shaped surface and the sloped surface cooperate with each other. The drive electric cylinder 26 is mounted on the sliding ram frame 1. The output end of the drive electric cylinder 26 is fixedly connected to the inner bottom of the U-shaped insertion frame 25. The drive electric cylinder 26 drives the bottom of the U-shaped insertion frame 25 to move into the two lifting clamping slots 6. The wedge-shaped surface at the bottom of the U-shaped insertion frame 25 contacts the slope surface of the connecting plate 22. As the wedge-shaped surface and the slope surface continue to contact, the connecting plate 22 is pushed to move in the direction of the mounting protrusion 19. When the U-shaped insertion frame 25 moves upward, under the action of the spring damper 24, the sliding groove 21 and the connecting plate 22 move laterally in the lifting clamping slots 6, so that the connecting plate 22 stops contacting the friction surface 20.

[0042] The working principle of the tool locking slide structure of this milling and turning composite equipment:

[0043] When the lead screw transmission structure 2 stops longitudinally moving the tool drive device 3 and the sliding seat 4, the drive motor 10 is started, which drives the rotating bushing 9 and the rotating cylinder 7 to rotate through the gearbox 8, causing the positioning block 5 to shift along the center point of the rotating cylinder 7, so that the positioning block 5 can enter the meshing clamp 16. Then, the specific positioning block 5 in the meshing clamp 16 is determined, the horizontal height of the tool drive device 3 is determined, and the height change after the rotating cylinder 7 is raised by the spring damper 12 is accurately measured to determine the specific position of the positioning tool drive device 3 after it stops.

[0044] The drive electric cylinder 26 is activated to move the bottom of the U-shaped insertion frame 25 into the two lifting clamping slots 6. The wedge-shaped surface at the bottom of the U-shaped insertion frame 25 contacts the slope surface of the connecting plate 22. As the wedge-shaped surface and the slope surface continue to contact, the connecting plate 22 is pushed to move towards the mounting protrusion 19, so that the friction groove 23 on the connecting plate 22 contacts the friction surface 20 in the lifting clamping slots 6, so that the mounting protrusion 19 enters the range of the friction groove 23, fixing the connecting plate 22 and further locking the tool drive device 3.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
