Description

Technical Field

[0001] This utility model relates to the field of machine tool waste collection technology, specifically a CNC machine tool waste collection device. Background Technology

[0002] CNC machine tools are automated machine tools controlled by a program control system. This control system can logically process programs with control codes or other symbolic instructions. CNC machine tools are characterized by high machining accuracy, high flexibility, and high productivity, and are widely used in many fields such as machining.

[0003] The invention disclosed in CN221110929U discloses a waste chip collection device for CNC machine tool processing. The device includes a machine tool, a motor mounted on the right end of the machine tool via a support plate, a rotating rod fixedly connected to the motor's output shaft, a connecting rod rotatably connected to the right end of the rotating rod, a circular tube rotatably connected to the left end of the connecting rod, and a flat plate fixedly connected to the left end of the circular tube. A separation box is located at the bottom of the machine tool, with a filter frame slidably connected through the inner wall of the separation box. A handle is fixedly connected to the left side wall of the filter frame. The rotating rod and connecting rod rotate when the motor rotates, causing the flat plate to move left and right, thus processing accumulated waste chips and preventing them from accumulating in one place for extended periods and affecting subsequent processing.

[0004] While the above technical solution can collect debris and improve processing efficiency to some extent, the internal filter is installed through a handle, torsion spring, support tube, and locking block. Disassembly requires stopping the machine to replace the filter, which can easily affect the processing efficiency of metal workpieces. Utility Model Content

[0005] The purpose of this utility model is to provide a waste chip collection device for CNC machine tools, which solves the problem that existing machine tool filters need to be replaced by stopping the machine, thus affecting the workpiece processing efficiency, by using a combination of replacement parts and anti-clogging parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A CNC machine tool waste chip collection device includes a machine tool, a control panel mounted on the machine tool, a dust collection box installed inside the machine tool, and further includes: fixed plates symmetrically installed inside the machine tool, each fixed plate having a spring fixedly connected to its top, and multiple springs having sliding plates fixedly connected to their tops, two of the sliding plates being slidably connected to the side wall of the machine tool, each of the two sliding plates having a detachable filter frame installed inside, and each of the two filter frames having a detachable filter screen; a replacement component mounted on the sliding plates for replacing the filter screen without stopping the machine; and an anti-clogging mechanism installed below the replacement component to prevent the filter screen from clogging.

[0008] Preferably, the replacement component includes a mounting plate fixedly installed between two sliding plates. The mounting plate has a through hole, and the two sliding plates have symmetrical mounting grooves on their adjacent sides. The mounting grooves can accommodate the filter frame, and the size of the through hole is the same as that of the filter screen.

[0009] Preferably, the filter frame is symmetrically fixedly connected with fixed blocks, and each of the two fixed blocks is rotatably connected with an adjusting bolt. Each of the two adjusting bolts is rotatably connected with a movable block at one end that is close to the other, and both movable blocks are slidably connected to the filter frame.

[0010] Preferably, baffles are symmetrically fixedly connected between the two sliding plates, and each of the two baffles is provided with a through groove for the fixing block and adjusting bolt on the filter frame to pass through.

[0011] Preferably, both baffles are symmetrically rotatably connected with lead screws, both lead screws are fixedly connected to the outside of both lead screws, both lead screws are threadedly connected to sliders, and a long rod is fixedly connected to the bottom of the lower slider.

[0012] Preferably, the anti-blocking mechanism includes a motor, which is installed inside the machine tool. The output end of the motor is fixedly connected to a drive wheel, and a driven wheel is rotatably connected to the side wall of the machine tool. The drive wheel and the driven wheel are synchronously provided with belts on their exteriors.

[0013] Preferably, both the driving wheel and the driven wheel are coaxially fixedly connected to rotating rods, both rotating rods are rotatably connected to the side wall of the machine tool, and both rotating rods are fixedly connected to the outside of a cam, which contacts the long rod when rotating.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model is equipped with a replacement component. By turning the handle, the lead screw is rotated, which in turn drives the sliding movement, thereby moving the filter frame and filter screen. This allows the filter screen to be replaced without stopping the machine, which facilitates the collection of debris and improves the working efficiency of the equipment.

[0016] This utility model is equipped with an anti-clogging component. The motor drives the drive wheel to rotate, which in turn drives the driven wheel to rotate via a belt. This, in turn, drives the cam outside the rotating rod to rotate, thereby impacting the long rod. The mounting plate then moves under the elastic force of the spring, causing the filter frame and filter screen to vibrate. This prevents debris from clogging the filter screen, thus improving debris collection and workpiece processing efficiency. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] The following description is intended to disclose the present invention and to enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0028] Example 1: Please refer to Figures 1-7 The diagram illustrates a CNC machine tool waste chip collection device, comprising a machine tool 1, a control panel 2 mounted on the machine tool 1, and a dust collection box 28 installed inside the machine tool 1. The dust collection box 28 is responsible for collecting fine dust generated during the machining process, preventing dust from flying freely inside the machine tool 1, thus effectively ensuring the cleanliness of the precision parts inside the machine tool 1, extending their service life, and creating a relatively healthy working environment for the operators. It also includes: fixed plates 3 symmetrically installed inside the machine tool 1, each fixedly connected to a spring 4 at its top, and each spring 4 having a sliding plate 7 fixedly connected to its top. Both sliding plates 7 are slidably connected to the side wall of the machine tool 1. Next, filter frames 11 are detachably installed inside both sliding plates 7, and filter screens 15 are detachably installed inside both filter frames 11. The filter screens 15 are made of stainless steel and can filter small waste particles while intercepting and collecting larger waste particles, laying the foundation for subsequent centralized processing. Also, a replacement component 5 is installed on the sliding plate 7. The replacement component 5 is used to replace the filter screens 15 without stopping the machine. The replacement component 5 can effectively reduce the production interruption time caused by equipment downtime maintenance, significantly improving the continuity of equipment operation and overall production efficiency. Finally, an anti-clogging mechanism 6 is installed below the replacement component 5 to prevent the filter screens 15 from clogging.

[0029] Furthermore, the replacement component 5 includes a mounting plate 8 fixedly installed between the two sliding plates 7. The mounting plate 8 has through holes 27 providing filtration space for the filter screen 15. Each of the two sliding plates 7 has symmetrical mounting grooves 26 on its adjacent side, which can accommodate the filter frame 11. The size of the through holes 27 is the same as that of the filter screen 15. When the filter screen 15 needs to be replaced, the filter frame 11 can be easily installed and removed along the mounting grooves 26. It is worth mentioning that the size of the through holes 27 is the same as that of the filter screen 15. This precise size matching design ensures that when replacing the filter screen 15, the new filter screen 15 can be accurately aligned with the installation position, smoothly completing the replacement process.

[0030] Furthermore, fixed blocks 12 are symmetrically fixedly connected to the filter frame 11. Adjusting bolts 14 are rotatably connected inside the two fixed blocks 12. Movable blocks 13 are rotatably connected to the ends of the two adjusting bolts 14 that are close to each other. The two movable blocks 13 are slidably connected to the filter frame 11. By rotating the adjusting bolts 14, the movable blocks 13 can be precisely controlled to fix the slider 23 behind.

[0031] Specifically: baffles 9 are symmetrically fixedly connected between the two sliding plates 7. Each baffle 9 has a through groove 10 for the fixed block 12 and adjusting bolt 14 on the filter frame 11 to pass through, ensuring effective guidance and positioning of the filter frame 11 during movement. This ensures a precise and smooth operation for replacing the filter screen 15. Screws 22 are symmetrically rotatably connected to each of the two baffles 9. Handles 24 are fixedly connected to the outside of each screw 22, and sliders 23 are threaded onto each screw 22. A long rod 25 is fixedly connected to the bottom of the lower slider 23. By rotating the handle 24, the screw 22 rotates, which in turn moves the slider 23, thereby moving the filter frame 11 and the filter screen 15. This allows for filter screen 15 replacement without stopping the machine, facilitating debris collection, improving equipment efficiency, and significantly reducing maintenance time and labor costs, thus providing strong support for efficient production.

[0032] Example 2: This embodiment is a further explanation of Example 1, based on... Figure 1 , Figure 3 and Figure 6 As shown, it is worth noting that the anti-blocking mechanism 6 includes a motor 16, which serves as the power source for the entire anti-blocking mechanism 6. The motor 16 is installed inside the machine tool 1, and the output end of the motor 16 is fixedly connected to a drive wheel 18. A driven wheel 20 is rotatably connected to the side wall of the machine tool 1. A belt 19 is synchronously provided on the outside of the drive wheel 18 and the driven wheel 20.

[0033] For details, please refer to Figure 5 As shown, both the driving wheel 18 and the driven wheel 20 are coaxially fixedly connected to rotating rods 17. Both rotating rods 17 are rotatably connected to the side wall of the machine tool 1. Cams 21 are fixedly connected to the outside of each rotating rod 17. During rotation, the special contour shape of the cams 21 causes them to periodically contact the long rod 25. When the motor 16 starts, it drives the cams 21 to strike the long rod 25. The long rod 25 drives the slider 23 to move upward, thereby causing the sliding plate 7 to slide along the side wall of the machine tool 1. Under the action of the spring 4, it resets, repeatedly vibrating the filter frame 11 and the filter screen 15, thus preventing clogging and ensuring that the filter screen 15 always maintains good filtration performance.

[0034] It is worth mentioning that the cam 21 adopts a symmetrical design, so that regardless of whether the filter screen 15 below is in working state, one of the cams 21 can hit the long rod 25, thereby preventing the filter screen 15 from being blocked. This continuously provides vibration anti-blocking power to the filter screen 15, ensuring that the filter screen 15 is always unobstructed, and providing a solid guarantee for the efficient and stable operation of the CNC machine tool 1.

[0035] The principle behind this solution is as follows:

[0036] First, when it is necessary to replace the filter frame 11 and the filter screen 15, turn the lower handle 24. The handle 24 drives the lead screw 22 to rotate, which in turn drives the slider 23 to move, thereby moving the filter frame 11 and the filter screen 15. When the lower filter screen 15 moves to below the through hole 27, turn the upper handle 24 to make the upper filter screen 15 disengage from the through hole 27 and move to the outer end.

[0037] Next, rotate the adjusting bolt 14 to move the movable block 13 away from the slider 23, thereby disengaging the filter frame 11 from the mounting slot 26. Then, replace the filter frame 11 and filter screen 15. When replacing the filter screen 15, simply pause the motor 16; there is no need to stop the machine tool 1.

[0038] Finally, when the machine tool 1 generates waste chips during the processing of the workpiece, the motor 16 is started. The motor 16 drives the driven wheel 20 to rotate through the drive wheel 18 and the belt 19, thereby driving the rotating rod 17 to rotate, which in turn drives the cam 21 to strike the long rod 25. The long rod 25 drives the slider 23 to move upward, thereby driving the sliding plate 7 to slide along the side wall of the machine tool 1, and then reset under the action of the spring 4. This cycle repeats to vibrate the filter frame 11 and the filter screen 15, thereby preventing them from clogging.

Furthermore, under the teachings of this utility model, modifications to these features and embodiments can be made to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
