Description

Technical Field

[0001] The present invention relates to the technical field of locking ram, and specifically, to a tool locking ram structure of a turning-milling composite equipment. Background Art

[0002] A turning-milling composite equipment is a composite equipment in the prior art that combines two processing modes of numerical control turning and milling during the processing of workpieces, and is used for continuous turning and milling of specific workpieces to improve the continuity of workpiece processing. During the use of the turning-milling composite equipment, the tools and tool driving equipment for the milling equipment of the workpiece are both installed through a locking ram structure, and the locking ram structure can also enable the tools and tool driving equipment to perform precise longitudinal movement. The ram structure generally uses a lead screw drive mechanism to move the tool driving equipment sliding on the ram. For the existing locking ram in the prior art, after the lead screw drive mechanism stops moving the tool driving equipment, a mechanical structure is used to lock the tool driving equipment.

[0003] During the process of installing the corresponding tool on the tool driving equipment and when the tool driving equipment switches between multiple tools, due to the differences in the shapes of different tools and the machining positions of the workpieces, after changing the tool, it is necessary to adjust the position of the tool driving equipment. This results in a large-range movement of the tool driving equipment on the ram structure. When the tool driving equipment moves in a large range, the existing ram structure needs to perform a full-range locking operation on the sliding area of the tool driving equipment, rather than performing targeted locking on the position where the tool driving equipment stops. This working method is difficult to perform targeted locking operations on different positions of the tool driving equipment on the ram structure, not only prone to the problem of loose locking of the tool driving equipment, but also affecting the positioning problem during the use of the tool driving equipment.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of the present invention.

[0034] As Figures 1 to 11 shown, this embodiment proposes a tool locking ram structure for a turning-milling composite device, including a ram frame 1. A lead screw drive structure 2 is arranged on one side inside the ram frame 1. A tool drive device 3 is longitudinally slidably arranged in the ram frame 1. Both sides inside the ram frame 1 are slidably connected with sliding seats 4. One of the sliding seats 4 is matched with the lead screw drive structure 2. The ram frame 1 is horizontally movably arranged on the processing machine table of the turning-milling composite device. After the turning-milling composite device clamps the workpiece, it drives the ram frame 1 to move on the processing machine table and drives it through the lead screw drive structure 2 to adjust the position of the tool drive device 3 so that the workpiece contacts the turning-milling tool and completes the turning-milling operation of the workpiece.

[0035] It further includes positioning blocks 5. The number of positioning blocks 5 is set to be multiple. The multiple positioning blocks 5 are grouped in pairs. Inside the ram frame 1, there is a flipping and offsetting component that drives the multiple positioning blocks 5 to offset. The flipping and offsetting component includes a rotating cylinder 7 and a gearbox 8. The rotating cylinder 7 is rotatably arranged through the ram frame 1. An elastic compensation structure is arranged between the rotating cylinder 7 and the inner bottom wall of the ram frame 1. A plurality of mounting rings are fixedly sleeved on the rotating cylinder 7. 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 gearbox 8 is drivingly arranged on the rotating shaft sleeve 9. A driving motor 10 is arranged on the top of the ram frame 1. The output end of the driving motor 10 is drivingly matched with the gearbox 8. After the tool driving device 3 longitudinally moves inside the ram frame 1, the two sliding seats 4 move longitudinally inside the ram frame 1 together. After the tool driving device 3 stops moving, the driving motor 10 is started. The rotating shaft sleeve 9 and the rotating cylinder 7 are driven to rotate through the gearbox 8, driving the positioning blocks 5 to offset along the center point of the rotating cylinder 7, so that the positioning blocks 5 can enter the meshing clamp seat 16;

[0036] The elastic compensation structure includes a support ring sleeve 11 and a first spring damper 12. The support ring sleeve 11 is fixedly connected to the inner bottom wall of the ram 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 matched with the inner side wall of the annular inner groove. The bottom of the rotating cylinder 7 longitudinally moves in the annular inner groove. The first spring damper 12 is arranged on the top of the support ring sleeve 11. The first spring damper 12 is located inside the rotating cylinder 7. A partition plate 13 is fixedly connected to the inner wall of the rotating cylinder 7. The top of the first spring damper 12 is rotatably connected to the partition plate 13. When there is a slight misalignment between the positioning block 5 and the meshing clamp seat 16, in order to make the positioning block 5 enter the meshing clamp seat 16, after the positioning block 5 contacts the V-shaped elastic clamp 17, the first spring damper 12 adaptively drives the rotating cylinder 7 to move up or down. The rotating cylinder 7 is slidably connected to the rotating shaft sleeve 9. An internal area for the longitudinal movement of the rotating cylinder 7 is reserved in the annular inner groove, so that the positioning block 5 enters the corresponding meshing clamp seat 16.

[0037] An induction ring sleeve 14 is arranged on the top of the rotating cylinder 7. A distance measuring sensor 15 is arranged on the upper side of the induction ring sleeve 14. The distance measuring sensor 15 is arranged on the ram frame 1. In order to position the position of the tool driving device 3 after it stops moving, first determine which positioning block 5 is specifically in the meshing clamp seat 16, judge the horizontal height of the tool driving device 3, and accurately measure the specific position of the tool driving device 3 after it stops according to the height change after the first spring damper 12 drives the rotating cylinder 7 to rise.

[0038] Among them, a meshing positioning component is provided between the corresponding multiple positioning blocks 5 and the sliding seats 4 on the same side. The meshing positioning component is used to lock and position the tool driving device 3. The meshing positioning component includes a meshing clamp seat 16 and a V-shaped elastic clamp 17. A plurality of meshing clamp seats 16 are longitudinally arranged on the inner walls of both sides 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 provided with inclined surfaces. A V-shaped elastic clamp 17 adapted to the positioning block 5 is arranged 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 close fit between the positioning block 5 and the inner wall of the V-shaped elastic clamp 17.

[0039] Lifting clamp grooves 6 are provided on both sides of the ram frame 1. The tool driving device 3 is slidably arranged between the two lifting clamp grooves 6. Lifting sliding grooves are formed on the outer walls of the lifting clamp grooves 6. A sliding member 18 is slidably connected to the lifting sliding grooves. The sliding member 18 is fixedly connected to the tool driving device 3. To improve the lifting stability of the tool driving device 3, the middle part of the tool driving device 3 slides on the lifting sliding grooves through the sliding member 18.

[0040] Installation protrusions 19 are arranged on the inner walls of the lifting clamp grooves 6. Friction surfaces 20 are arranged on the installation protrusions 19. A clamping and locking mechanism is provided between the tool driving device 3 and the two lifting clamp grooves 6. The clamping and locking mechanism includes a sliding groove body 21 and a lifting extrusion component. The sliding groove body 21 is horizontally slidably connected in the lifting clamp groove 6. A connecting plate body 22 is longitudinally slidably connected in the sliding groove body 21. The connecting plate body 22 is horizontally slidably connected to the tool driving device 3. Among them, a friction groove 23 is arranged on one side of the connecting plate body 22 close to the friction surface 20. The friction groove 23 cooperates with the friction surface 20. A lifting extrusion component for driving the connecting plate body 22 to move is arranged between the tops of the two lifting clamp grooves 6. When it is necessary to lock the tool driving device 3, the connecting plate body 22 moved to the corresponding position is driven to move horizontally by the lifting extrusion component, so that the friction groove 23 on the connecting plate body 22 contacts the friction surface 20 in the lifting clamp groove 6, and the installation protrusion 19 enters the range of the friction groove 23 to fix the connecting plate body 22, and further lock the tool driving device 3;

[0041] A second spring damper 24 is arranged between the inner side wall of the sliding groove body 21 and the inner side wall of the lifting clamping groove 6. The lifting extrusion assembly includes a U-shaped insertion frame 25 and a driving electric cylinder 26. The bottom of the U-shaped insertion frame 25 penetrates and is slidably connected in the lifting clamping groove 6. The bottom of the U-shaped insertion frame 25 is provided with a wedge-shaped surface, and the middle of the connecting plate body 22 is provided with a slope-shaped surface. The wedge-shaped surface and the slope-shaped surface cooperate with each other. The driving electric cylinder 26 is arranged on the ram frame 1, and the output end of the driving electric cylinder 26 is fixedly connected to the inner bottom of the U-shaped insertion frame 25. Starting the driving electric cylinder 26 drives the bottom of the U-shaped insertion frame 25 to move into the two lifting clamping grooves 6. The wedge-shaped surface at the bottom of the U-shaped insertion frame 25 contacts the slope-shaped surface of the connecting plate body 22. As the wedge-shaped surface and the slope-shaped surface continuously contact, the connecting plate body 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 second spring damper 24, the sliding groove body 21 and the connecting plate body 22 move horizontally in the lifting clamping groove 6, so that the connecting plate body 22 stops contacting the friction surface 20.

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

[0043] When the lead screw drive structure 2 stops longitudinally moving the tool driving device 3 and the sliding seat 4, start the driving motor 10 to drive the rotating shaft sleeve 9 and the rotating cylinder 7 to rotate through the gearbox 8, drive the positioning block 5 to offset along the center point of the rotating cylinder 7, so that the positioning block 5 can enter the meshing clamp seat 16. Then determine which positioning block 5 in the meshing clamp seat 16 is, judge the horizontal height of the tool driving device 3, and accurately measure the specific position of the tool driving device 3 after it stops according to the height change after the first spring damper 12 drives the rotating cylinder 7 to rise;

[0044] And start the driving electric cylinder 26 to drive the bottom of the U-shaped insertion frame 25 to move into the two lifting clamping grooves 6. The wedge-shaped surface at the bottom of the U-shaped insertion frame 25 contacts the slope-shaped surface of the connecting plate body 22. As the wedge-shaped surface and the slope-shaped surface continuously contact, the connecting plate body 22 is pushed to move in the direction of the mounting protrusion 19, so that the friction groove 23 on the connecting plate body 22 contacts the friction surface 20 in the lifting clamping groove 6, so that the mounting protrusion 19 enters the range of the friction groove 23 to fix the connecting plate body 22 and further lock the tool driving device 3.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
