Description

Technical Field

[0001] The present invention relates to the technical field of numerical control machine tools, and specifically refers to a chip removal and cleaning device for a numerical control machine tool. Background Art

[0002] The chip removal and cleaning device of a numerical control machine tool is a key auxiliary device for a numerical control machine tool. It has significant functions, can ensure machining accuracy, prevent chips from affecting the guide rail and lead screw, and avoid damage to accuracy; improve machining efficiency and reduce the chip cleaning time during downtime; protect machine tool components and reduce the risk of chip corrosion. There are various types, including chain plate type, scraper type, spiral type and magnetic chip conveyors, which are respectively suitable for chips of different shapes and materials. It mainly consists of chip removal, drive, conveying channel, chip collection box and other parts.

[0003] In the current field of machining, although the chip removal and cleaning device of a numerical control machine tool effectively undertakes the task of discharging chips, there is an obvious shortcoming. The existing device only discharges all kinds of chips generated during the machining process without any screening function. In actual production, the subsequent recycling methods of chips with different sizes, shapes and materials are completely different. For example, larger metal chips may be directly remelted in a furnace, while smaller chips may require special processing techniques. Due to the lack of screening, additional sorting processes have to be arranged after the chips are discharged, which undoubtedly greatly increases the complexity of the overall process, consumes a large amount of time cost, and drags down the production efficiency. Summary of the Invention

[0004] In order to solve the above various problems, the present invention proposes a chip removal and cleaning device for a numerical control machine tool that directly classifies the chips during chip removal and discharging, facilitating subsequent recycling processes.

[0005] To solve the above technical problems, the technical solution proposed by the present invention is: a chip removal and cleaning device for a numerical control machine tool, comprising:

[0006] A chip removal pipe, one end of the upper part is provided with a feed hopper communicated therewith, and a screw conveyor is rotatably connected inside. The screw conveyor is driven by a motor fixedly arranged at one end of the chip removal pipe. The chip removal pipe is provided with a discharge port at the end far from the feed hopper at the lower part;

[0007] A screening assembly, comprising a plurality of sieve meshes and discharge guiding hoppers. The sieve meshes are detachably arranged on the lower wall of the chip removal pipe, and the discharge guiding hoppers are arranged below the sieve meshes and correspond to the sieve meshes one by one;

[0008] A vibration mechanism, arranged at one end of the chip removal pipe, comprising a vibrator and a vibrating rod. One end of the vibrating rod is connected to the vibrator and driven by the vibrator, and the other end is in contact with the chip removal pipe.

[0009] Further, the sieve holes of the sieve mesh gradually increase from the end close to the feed hopper to the end far from the feed hopper.

[0010] Further, a support is fixedly provided below the chip removal pipe. The support is in the shape of a three-fold plate, and the discharge guiding hopper is fixedly provided on the support.

[0011] Further, the rear end of the discharge guiding hopper is inclined upward.

[0012] Further, a vertical support plate is fixedly provided on the side wall of the feed hopper, and the vibrator is fixedly provided at the lower end of the vertical support rod.

[0013] The advantages of the present invention compared with the prior art are as follows: A plurality of screen meshes are detachably arranged on the lower wall of the chip removal pipe, and the screen holes of the screen meshes increase in sequence from the end close to the feed hopper to the end far from the feed hopper. When the motor drives the auger to convey the chips entering the chip removal pipe from the feed hopper, chips of different sizes will be screened by the screen meshes with different screen holes during the moving process. Small particle chips will first fall through the small screen hole screen mesh close to the feed hopper, and large particle chips will be screened out when passing through the large screen hole screen mesh subsequently. A discharge guiding hopper is correspondingly provided below each screen mesh, and chips of different sizes after screening will be discharged through the corresponding discharge guiding hopper, realizing classification during chip removal and discharging.

[0014] The vibrator makes the chip removal pipe vibrate through the vibrating rod, preventing chips from blocking the screen mesh and ensuring the smooth progress of the screening process. This way of directly completing classification during chip removal eliminates the need for cumbersome classification operations in subsequent recycling processes, saving time and labor costs and improving the recycling efficiency.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Combined with the attached Figure 1 、attached Figure 2 、attached Figure 3, A chip removal and cleaning device for a numerical control machine tool, comprising: a chip removal pipe 1, with a feed hopper 2 connected to its upper end, and a screw conveyor 3 rotatably connected inside. The screw conveyor 3 is driven by a motor 4 fixedly arranged at one end of the chip removal pipe 1. An outlet is arranged at the end of the chip removal pipe 1 away from the feed hopper 2 below; a screening component, including a plurality of sieves 5 and a discharge guiding hopper 6. The sieves 5 are detachably arranged on the lower wall of the chip removal pipe 1. The sieve holes of the sieves 5 gradually increase from the end close to the feed hopper 2 to the end far from the feed hopper 2, enabling multi-stage screening of chips of different sizes. The sieve 5 with small sieve holes close to the feed hopper 2 first screens out small particle chips, and then the sieve 5 with large sieve holes screens out large particle chips, improving the accuracy of screening.

[0022] Combined with the attached Figure 1 , the attached Figure 4 , The discharge guiding hopper 6 is arranged below the sieve 5 and corresponds to the sieve 5 one by one. A support 9 is fixedly arranged below the chip removal pipe 1. The support 9 is in the shape of a three-fold plate. The discharge guiding hopper 6 is fixedly arranged on the support 9, which can provide stable support for the chip removal pipe 1, ensure the overall stability of the device, and at the same time provide a reliable installation foundation for the discharge guiding hopper 6, making the device structure more stable. The rear end of the discharge guiding hopper 6 is inclined upward, which can prevent the screened chips from accumulating at the rear end of the discharge guiding hopper 6, ensure that the chips can be smoothly discharged from the discharge guiding hopper 6, improve the chip removal efficiency, and ensure the normal operation of the device.

[0023] Combined with the attached Figure 1 , A vibration mechanism is arranged at one end of the chip removal pipe 1, including a vibrator 7 and a vibrating rod 8. One end of the vibrating rod 8 is connected to the vibrator 7 and driven by the vibrator 7, and the other end is in contact with the chip removal pipe 1. A vertical support plate 10 is fixedly arranged on the side wall of the feed hopper 2. The vibrator 7 is fixedly arranged at the lower end of the vertical support plate 10. The vibrator 7 is stably installed beside the feed hopper 2 through the vertical support plate 10, enabling the vibrator 7 to better play its role, transmitting stable vibration to the vibrating rod 8, and promoting chip removal and screening in the chip removal pipe 1.

[0024] The specific implementation manner of the present invention: First, install the device near the machine tool, ensure that the chip discharge port of the machine tool is directly above the feed hopper 2, and connect the device to an external power supply. The chips generated by the machine tool enter the chip removal pipe 1 connected to the feed hopper 2. Start the motor 4 fixedly arranged at one end of the chip removal pipe 1. The motor 4 drives the screw conveyor 3 rotatably connected inside the chip removal pipe 1 to start rotating. The screw conveyor 3 conveys the chips from one end of the feed hopper 2 to the end of the chip removal pipe 1 away from the feed hopper 2.

[0025] During the conveying process, several screen meshes 5 detachably arranged on the lower wall of the chip removal pipe 1 play a screening role. Since the screen holes of the screen mesh 5 gradually increase from the end close to the feed hopper 2 to the end far from the feed hopper 2, chips of different sizes will be classified and screened. Small particle chips first pass through the small screen hole screen mesh 5 close to the feed hopper 2, and large particle chips are screened out when they pass through the large screen hole screen mesh 5 subsequently. An outlet guiding hopper 6 is provided below each screen mesh 5, and the screened chips will be discharged through the corresponding outlet guiding hopper 6. Finally, the larger chips are discharged from the outlet at the end of the chip removal pipe 1 far from the feed hopper 2 below.

[0026] Meanwhile, the vibration mechanism located at one end of the chip removal pipe 1 starts to work. The vibrator 7 fixed at the lower end of the vertical support plate 10 on the side wall of the feed hopper 2 drives the vibration rod 8. The vibration rod 8 contacts the chip removal pipe 1 to make the chip removal pipe 1 vibrate, preventing chips from clogging the screen mesh 5.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; for those of ordinary skill in the art, the specific meaning of the above terms in the present invention can be understood according to specific situations.

[0028] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the purpose of the present invention, they should fall within the protection scope of the present invention.
