Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a CNC machine tool worktable that facilitates chip removal. Background Technology

[0002] The CNC machine tool worktable is an important component of the machine tool, mainly used to support and fix the workpiece to ensure machining accuracy and stability. Depending on the function, the worktable can be divided into fixed worktable and rotary worktable. Currently, when cleaning debris, the device can only clean debris on the surface of the workbench, making it difficult to achieve a comprehensive and thorough cleaning of debris remaining inside the workbench. Meanwhile, when clamping a workpiece, the device usually clamps it according to the size of the workpiece, and it is impossible to accurately know whether the movement distance of the clamping point of the device is the same. This can easily cause the workpiece to deviate during the clamping process, and excessive clamping force can easily damage the workpiece.

[0003] Therefore, we propose a CNC machine tool worktable that facilitates chip removal in order to solve the problems mentioned above. Utility Model Content

[0004] This invention proposes a CNC machine tool worktable that facilitates chip removal, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a workbench, a chip removal mechanism, and a positioning mechanism. The chip removal mechanism includes a cleaning brush and a disc brush. The cleaning brush is located between the disc brushes. The cleaning brush and the disc brush are used to clean and remove the debris stored on the workbench, thereby improving the chip removal efficiency. The positioning mechanism includes a sliding seat, a measuring block, and a positioning block. The rear surface of the measuring block is fixedly connected to the front surface of the sliding seat. The sliding seat, measuring block, and positioning block are used to perform positioning measurement for workpiece clamping to prevent excessive workpiece clamping force from causing workpiece damage.

[0006] Preferably, the chip removal mechanism further includes a slider, which is slidably connected to the inner wall of the worktable. A movable plate is fixedly connected to the rear surface of the slider, and the lower surface of the movable plate is fixedly connected to the upper surface of the cleaning brush. A rotating rod is movably connected to the lower surface of the movable plate through a bearing, and the bottom end of the rotating rod is fixedly connected to the upper surface of the disc brush. A sliding sleeve is fixedly connected to the upper surface of the movable plate.

[0007] Preferably, the positioning mechanism further includes a limiting plate, the lower surface of which is fixedly connected to the upper surface of the sliding seat, the interior of which is slidably connected to the positioning block, and a fixing rod is slidably connected inside the limiting plate, with the bottom end of the fixing rod being fitted into the interior of the positioning block.

[0008] Preferably, the upper surface of the worktable is fixedly connected to the lower surface of the sliding seat, a motor is provided on the side surface of the worktable, and a lead screw is fixedly connected to the output end of the motor, and the lead screw is connected to the internal thread of the sliding sleeve.

[0009] Preferably, a clamping plate is slidably connected inside the sliding seat, and the front surface of the clamping plate is fixedly connected to the rear surface of the positioning block. A spring is fixedly connected inside the clamping plate, and a shaped rod is fixedly connected to the end of the spring away from the clamping plate. The shaped rod is slidably connected to the inside of the clamping plate, and a rubber sleeve is fitted on the outer surface of the shaped rod, with the rubber sleeve located to the right of the spring.

[0010] Preferably, the upper surface of the workbench has an opening, and the side surface of the workbench has a chip removal port.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when the moving plate is moving, the cleaning brush can push the debris accumulated inside the workbench forward. When the moving plate moves, the edge of the disc brush rubs against the inner wall of the workbench. The friction causes the disc brush to rotate. The hard bristles on the disc brush will deform during the friction, producing a sweeping action, effectively pushing the debris attached to the edges and corners of the workbench towards the central area of ​​the workbench. The debris collected by the cleaning brush and the disc brush is finally discharged from the workbench through the chip discharge port opened on the side of the workbench.

[0012] 2. In this utility model, the distance between the clamping plates can be adjusted by sliding the clamping plate and the sliding seat. When the clamping plate is sliding, the moving distance of the positioning block can be detected by the measuring block. When the moving distance of the two sets of clamping plates is the same and the workpiece is clamped, the fixing rod passes through the limiting plate and is embedded in the interior of the positioning block to fix the clamping plate. This ensures that the moving distance of the clamping plate is exactly the same when clamping the workpiece, achieving consistency when clamping different workpieces and fundamentally avoiding clamping deviation caused by different clamping strokes.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1, as shown in the attached document Figures 1-4 As shown, it includes a worktable 1, a chip removal mechanism 7 and a positioning mechanism 4. The chip removal mechanism 7 includes a cleaning brush 706 and a disc brush 703. The cleaning brush 706 is located between the disc brushes 703. The cleaning brush 706 and the disc brush 703 are used to clean and remove the chips stored on the worktable 1, thereby improving the chip removal efficiency. The positioning mechanism 4 includes a sliding seat 401, a measuring block 403 and a positioning block 405. The rear surface of the measuring block 403 is fixedly connected to the front surface of the sliding seat 401. The sliding seat 401, the measuring block 403 and the positioning block 405 are used to perform positioning measurement on the workpiece clamping to prevent the workpiece from being damaged due to excessive clamping force.

[0018] The overall effect of Embodiment 1 is as follows: the cleaning brush 706 can clean the debris accumulated in the workbench 1. Since the disc brush 703 is attached to the edge of the workbench 1, the disc brush 703 is affected by friction during the movement of the moving plate 701. The hard bristles on the surface of the disc brush 703 can deform and push the debris at the edge of the workbench 1 towards the middle of the workbench 1, thereby improving the debris discharge effect. At the same time, by using the sliding of the positioning block 405 and the limiting plate 402, and by using the movement of the clamping plate 6, the movement distance of the positioning block 405 can be detected according to the measuring block 403, thereby improving the uniformity of the movement distance of the clamping plate 6, preventing workpiece clamping deviation due to different movement distances of the clamping plate 6, and reducing the risk of workpiece damage due to excessive clamping force.

[0019] Example 2, as Figures 1-3 As shown, the chip removal mechanism 7 also includes a slider 704, which is slidably connected to the inner wall of the worktable 1. A movable plate 701 is fixedly connected to the rear surface of the slider 704, and the lower surface of the movable plate 701 is fixedly connected to the upper surface of the cleaning brush 706. A rotating rod 705 is movably connected to the lower surface of the movable plate 701 through a bearing, and the bottom end of the rotating rod 705 is fixedly connected to the upper surface of the disc brush 703. A sliding sleeve 702 is fixedly connected to the upper surface of the movable plate 701. An opening 2 is provided on the upper surface of the worktable 1, and a chip removal port is provided on the side surface of the worktable 1. A motor 3 is provided on the side surface of the worktable 1, and a lead screw 8 is fixedly connected to the output end of the motor 3. The lead screw 8 is connected to the internal thread of the sliding sleeve 702.

[0020] The overall effect of embodiment 2 is as follows: when motor 3 is connected to an external power source and started, motor 3 drives lead screw 8 to rotate. The rotational motion of lead screw 8 is converted into linear motion by sliding sleeve 702. Moving plate 701 moves linearly along with sliding sleeve 702. Sliding block 704 is slidably connected to the inner wall of worktable 1, guiding the movement of moving plate 701. When moving plate 701 moves, cleaning brush 706 can push the debris accumulated inside worktable 1 forward. When moving plate 701 moves, the edge of disc brush 703 rubs against the inner wall of worktable 1. The friction causes disc brush 703 to rotate. The hard bristles on disc brush 703 deform during friction, producing a sweeping action, effectively pushing the debris attached to the edges and corners of worktable 1 towards the central area of ​​worktable 1. The debris collected by cleaning brush 706 and disc brush 703 is discharged from worktable 1 through the chip discharge port opened on the side of worktable 1.

[0021] Example 3, as Figure 2 and Figure 4As shown, the positioning mechanism 4 also includes a limiting plate 402. The lower surface of the limiting plate 402 is fixedly connected to the upper surface of the sliding seat 401. The interior of the limiting plate 402 is slidably connected to the positioning block 405. A fixing rod 404 is slidably connected to the interior of the limiting plate 402, and the bottom end of the fixing rod 404 is fitted into the interior of the positioning block 405. The upper surface of the worktable 1 is fixedly connected to the lower surface of the sliding seat 401. A clamping plate 6 is slidably connected to the interior of the sliding seat 401, and the front surface of the clamping plate 6 is fixedly connected to the rear surface of the positioning block 405. A spring 9 is fixedly connected to the interior of the clamping plate 6. A shaped rod 5 is fixedly connected to the end of the spring 9 away from the clamping plate 6, and the shaped rod 5 is slidably connected to the interior of the clamping plate 6. A rubber sleeve 10 is sleeved on the outer surface of the shaped rod 5, and the rubber sleeve 10 is located to the right of the spring 9.

[0022] The overall effect of embodiment 3 is as follows: the workpiece to be processed is placed on the surface of the workbench 1. The distance between the clamping plates 6 can be adjusted by sliding the clamping plate 6 and the sliding seat 401. When the clamping plate 6 is sliding, the moving distance of the positioning block 405 can be detected by the measuring block 403. When the moving distance of the two sets of clamping plates 6 is the same and the workpiece is clamped, the fixing rod 404 is inserted into the positioning block 405 through the limiting plate 402 to fix the clamping plate 6. This ensures that the moving distance of the clamping plate 6 is exactly the same when clamping the workpiece, achieving consistency when clamping different workpieces. This fundamentally avoids clamping deviation caused by different clamping strokes. When the clamping plate 6 is clamping the workpiece, the sliding of the shaped rod 5 inside the clamping plate 6 allows the shaped rod 5 to pull the spring 9. The rubber sleeve 10 can increase the friction when the shaped rod 5 moves. The shaped rod 5 can be used to clamp workpieces of different shapes.

[0023] The working principle of the entire equipment is as follows: The workpiece to be processed is placed on the surface of the worktable 1. The distance between the clamping plates 6 and the sliding seat 401 can be adjusted by sliding the clamping plates 6. When the clamping plates 6 are sliding, the moving distance of the positioning block 405 can be detected by the measuring block 403. When the moving distance of the two sets of clamping plates 6 is the same and the workpiece is clamped, the fixing rod 404 is inserted into the positioning block 405 through the limiting plate 402 to fix the clamping plates 6. The sliding of the irregular rod 5 with the inside of the clamping plate 6 allows the irregular rod 5 to pull the spring 9. The rubber sleeve 10 can increase the friction when the irregular rod 5 moves. The irregular rod 5 can be used to clamp workpieces of different shapes. After the workpiece is finished, the debris falls into the interior of the worktable through the opening. The motor 3 is started, and the motor 3 drives the lead screw 8 to rotate. The sliding sleeve 702 converts the rotational motion of the lead screw 8 into linear motion. The moving plate 701 moves linearly along with the sliding sleeve 702. The slider 704 is slidably connected to the inner wall of the worktable 1, which guides the movement of the moving plate 701. When the moving plate 701 moves, the cleaning brush 706 can push the debris accumulated inside the worktable 1 forward. When the moving plate 701 moves, the edge of the disc brush 703 rubs against the inner wall of the worktable 1. The friction causes the disc brush 703 to rotate. The hard bristles on the disc brush 703 will deform during the friction, producing a sweeping action, and the debris is discharged from the worktable 1 through the chip discharge port opened on the side of the worktable 1.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
