Description

Technical Field

[0001] This utility model relates to the field of CNC milling and turning composite machine tool technology, specifically a material removal mechanism for a CNC milling and turning composite machine tool. Background Technology

[0002] The material extractor is a key component of CNC milling and turning machines. During machining, after a workpiece completes one operation, it needs to be removed from the current clamping device (such as a pneumatic three-jaw chuck) or its extension length adjusted for further processing. Existing material extractors rely on mechanical structures such as levers, springs, and cams to achieve the material extraction action. However, their precision is not high, and they are only suitable for relatively slow-paced machining operations. Furthermore, they cannot flexibly control the opening and closing of the chuck according to the workpiece size, failing to meet the workpiece clamping requirements under different working conditions. Utility Model Content

[0003] The purpose of this invention is to provide a material removal mechanism for a CNC milling and turning machine tool to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a material removal mechanism for a CNC milling and turning machine tool, comprising: Workbench; A support plate is placed on top of the workbench, and an adjustment part is installed at the bottom of the support plate for adjusting the height of the support plate. A support frame is placed at one end of the top of the support plate. Two rotating chucks are symmetrically rotatably connected inside the support frame. A spring is fixed between the two rotating chucks. A drive unit is adjustablely installed on the top of the support plate. A drive cone block is fixedly connected to the output end of the drive unit to drive one end of the rotating chucks to close.

[0005] Preferably, the adjustment part includes a T-shaped limiting block, the top of which is fixedly connected to a threaded rod, and the middle of the worktable is provided with a T-shaped groove that mates with the limiting block.

[0006] Preferably, the threaded rod passes through the positioning base plate and the support plate from bottom to top, and a nut is threadedly connected to the outer side of the threaded rod and at the top of both the positioning base plate and the support plate.

[0007] Preferably, a fixing tube is fixedly connected to the top of the positioning base plate, an adjusting bolt is threadedly connected to the middle of the fixing tube, and a fastening nut is threadedly connected to the outer side of the adjusting bolt.

[0008] Preferably, a slide rail is fixedly connected to the top of the support plate, a slide block is slidably connected to the outside of the slide rail, and the driving part is fixedly connected to the top of the slide block. The driving part is a cylinder.

[0009] Preferably, a fixing plate is fixedly connected to one end of the top of the support plate, a fastening bolt is inserted into the middle of the fixing plate, one end of the fastening bolt is fixedly connected to the slide block, and two nuts are threadedly connected to the outer side of the fastening bolt and on both sides of the fixing plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the drive unit drives the drive cone block to squeeze one end of the rotary chuck, and the lever principle is used to cause the other end to contract to clamp the workpiece. Then, the workpiece is pulled out from the pneumatic three-jaw chuck by the movement of the worktable. After that, the drive unit resets, and the rotary chuck opens and resets under the action of the spring, which can complete the workpiece extraction operation and connect smoothly with the subsequent cutting process of the machine tool. By using the cooperation of the fixed tube, adjusting bolt and fastening nut, the height of the support plate can be adjusted according to actual needs, so that the rotary chuck can be well matched with workpieces of different heights, improving the versatility and adaptability of the equipment. A slide rail and slide block are set on the support plate, and the drive unit is fixed on the slide block. By using the cooperation of the fixed plate, fastening bolt and nut, the position of the slide block on the slide rail can be flexibly adjusted, thereby controlling the extreme position of the drive cone block movement, realizing the control of the opening and closing size of the rotary chuck, and meeting the workpiece clamping requirements under different working conditions.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a material removal mechanism for a CNC milling and turning composite machine tool, comprising: a worktable 1; a support plate 4 installed on the top of the worktable 1, an adjustment part installed at the bottom of the support plate 4 for adjusting the height of the support plate 4; a support frame 12 welded to one end of the top of the support plate 4, two rotating chucks 13 symmetrically rotatably connected inside the support frame 12, a spring 14 fixedly connected between the two rotating chucks 13, a drive part 8 adjustablely installed on the top of the support plate 4, and a drive cone block 9 fixedly connected to the output end of the drive part 8 for driving one end of the rotating chuck 13 to close.

[0015] It should be noted that in this embodiment, the end of the rotary chuck 13 is used for tool setting with the end of the workpiece. The machine tool drives the support plate 4 to move laterally and longitudinally through the worktable 1, so that the rotary chuck 13 is located at one end of the workpiece. The pneumatic three-jaw chuck holding the workpiece is released. The drive unit 8 squeezes the rotary chuck 13 from one end through the drive cone block 9, so that one end of the rotary chuck 13 is opened and the spring 14 is stretched. Under the action of the lever principle, the other end of the rotary chuck 13 contracts, thereby clamping the workpiece by the rotary chuck 13 closing and contracting. The machine tool drives the rotary chuck 13 to move laterally through the worktable 1, thereby pulling the workpiece out from the middle of the pneumatic three-jaw chuck and then retracting and clamping it. Then the drive unit 8 drives the drive cone block 9 to reset. The rotary chuck 13 opens and resets under the pull of the spring 14, so that the tool on the top of the worktable 1 cooperates with the end of the workpiece for cutting through the lateral movement.

[0016] In one embodiment, the adjustment part includes a T-shaped limiting block 3, a threaded rod 5 is fixedly connected to the top of the limiting block 3, a T-shaped groove that mates with the limiting block 3 is opened in the middle of the worktable 1, the threaded rod 5 passes through the positioning base plate 2 and the support plate 4 from bottom to top, and a nut is threadedly connected to the outer side of the threaded rod 5 and the top of the positioning base plate 2 and the top of the support plate 4.

[0017] It should be noted that in this embodiment, the T-shaped groove at one end of the workbench 1 will slide towards the middle of the workbench 1. After reaching a suitable position, the threaded rod 5 will pass through the top of the positioning base plate 2, placing the positioning base plate 2 on the top of the workbench 1. Then, the nut 1 will be installed on the outside of the threaded rod 5 and rotated downwards for adjustment. The nut 1 will be pressed against the top of the positioning base plate 2, thereby cooperating with the nut 1 and the limiting block 3 to press and fix the positioning base plate 2 on the top of the workbench 1.

[0018] In one embodiment, a fixing tube 15 is fixedly connected to the top of the positioning base plate 2, an adjusting bolt 16 is threadedly connected to the middle of the fixing tube 15, and a fastening nut 17 is threadedly connected to the outer side of the adjusting bolt 16.

[0019] It should be noted that, in this embodiment, after the positioning base plate 2 is fixed to the top of the worktable 1, the adjusting bolt 16 is rotated by a wrench according to the height that the support plate 4 needs to be adjusted. The adjusting bolt 16 is unscrewed from the inside of the fixing tube 15, so that it lifts the support plate 4 from the top, thereby adjusting the height position of the support plate 4, so as to facilitate the rotation of the chuck 13 and the workpiece. After adjusting to the designated position, the fastening nut 17 is tightened so that the fastening nut 17 is pressed tightly against the top of the fixing tube 15, thereby fixing the position of the adjusting bolt 16. The nut is then installed at the position where the threaded rod 5 passes through the top of the support plate 4, and then the nut is tightened so that the support plate 4 is pressed and fixed to the top of the fixing tube 15.

[0020] In one embodiment, a slide rail 6 is fixedly connected to the top of the support plate 4, a slide block 7 is slidably connected to the outside of the slide rail 6, a drive unit 8 is fixedly connected to the top of the slide block 7, the drive unit 8 is a cylinder, a fixing plate 10 is fixedly connected to one end of the top of the support plate 4, a fastening bolt 11 is inserted into the middle of the fixing plate 10, one end of the fastening bolt 11 is fixedly connected to the slide block 7, and nuts are threadedly connected to the outside of the fastening bolt 11 and on both sides of the fixing plate 10.

[0021] It should be noted that in this embodiment, the extreme position of the drive cone 9 is controlled by adjusting the position of the drive unit 8. In this way, the opening and closing size of the rotating chuck 13 is controlled by the position of the drive cone 9. During adjustment, the position of the second nut on the outer side of the fixing plate 10 is adjusted, and the slide block 7 is slid forward along the slide rail 6. When the appropriate position is reached, the second nuts on both sides of the fixing plate 10 are tightened to make the fixing plate 10 press and fit together, thereby adjusting the extreme position of the drive cone 9.
