Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and specifically to a splash-proof structure for CNC machine tools. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] The existing technology has the following problems:

[0004] In current CNC machine tools, the part is placed on the operating table and then limited, and the safety door is closed before starting the CNC machine tool. During this process, a large amount of debris will fly up during the machining of the part, and there is no anti-splash structure. As a result, the inside of the CNC machine tool is full of debris, which makes it difficult to clean up the debris after the part is machined. At the same time, it is also difficult to collect the debris, making it troublesome to clean up the debris after the part is machined.

[0005] Therefore, we need anti-splash structures for CNC machine tools to solve the above problems. Utility Model Content

[0006] This utility model provides a splash-proof structure for CNC machine tools to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A splash-proof structure for CNC machine tools includes a CNC machine tool body. A cutting fluid recovery tank is provided on the bottom inner side of the CNC machine tool body. Safety doors are provided on the left and right sides of the front inner side of the CNC machine tool body. An operating table is fixedly connected to the middle inner side of the CNC machine tool body.

[0009] The operating platform has sliding grooves on the upper front and rear sides. Sliders are slidably connected to the left and right sides of the sliding grooves. Protective plates are fixedly connected to the outer surfaces of the sliders. There are two protective plates, which are U-shaped mirror images. The upper front of the right protective plate has a positioning hole. The upper front of the left protective plate has a semi-circular block movably connected. Limiting grooves are opened on the lower opposite surfaces of the left and right protective plates. Clamping components are provided inside the left and right limiting grooves.

[0010] A further improvement of this utility model is that the clamping components on the left and right sides are respectively composed of two clamping blocks, a bidirectional threaded rod, and a handle.

[0011] A further improvement of this utility model is that: a positioning rod is slidably connected through the left side of the front of the semicircular block, a circular block is fixedly connected to the front end of the positioning rod, a spring is sleeved on the outer surface of the circular block, and the outer surface of the positioning rod corresponds to and cooperates with the positioning hole.

[0012] A further improvement of this utility model is that: an inner cavity is provided on the upper surface of the operating table, a frame-shaped baffle plate is fixedly connected to the upper part of the inner wall of the inner cavity, and a collection box is slidably connected to the lower part of the inner wall of the inner cavity.

[0013] A further improvement of this utility model is that: the upper surface of the frame-shaped barrier plate is provided with a plate, and the upper surface of the plate has a rectangular array of several circular openings.

[0014] A further improvement of this utility model is that the collection box is composed of a frame plate and a filter screen. The filter screen is fixedly connected to the lower inner side of the frame plate. The length of the frame plate is greater than the length of the operating table. A U-shaped handle is fixedly connected to the center of the front of the frame plate.

[0015] A further improvement of this utility model is that an opening is provided at the lower front of the operating table, and the interior of the opening is slidably connected to the outer surface of the frame plate.

[0016] A further improvement of this utility model is that: the lower surface of the operating table is provided with exhaust ports at both the front and rear, and a shim block is fixedly connected to the middle of the lower surface of the operating table.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] 1. This utility model provides an anti-splash structure for CNC machine tools. In use, the workpiece is placed on the operating table, and then the left and right protective plates are closed. By rotating the semicircular block, when it is rotated to the appropriate position, the positioning rod enters the positioning hole due to the elasticity of the spring, which facilitates the limiting of the left and right protective plates. At the same time, the workpiece is clamped and fixed by the clamping components in the left and right protective plates. Through the setting of this structure, the chips will not splash during the processing of the workpiece, and the chips will be concentrated between the two protective plates, so as to facilitate the subsequent cleaning of the chips.

[0019] 2. This utility model provides an anti-splash structure for CNC machine tools. When the worker picks up a brush to clean the surface of the plate, the debris falls into the collection box through the circular opening, which facilitates the collection of debris. When the collected debris needs to be cleaned, the collection box can be pulled out directly. In addition, the combination of filter screen, outlet and shim block facilitates the discharge of cutting fluid during workpiece processing. Attached Figure Description

Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1: As Figures 1 to 5As shown, this utility model provides an anti-splash structure for CNC machine tools, including a CNC machine tool body 1 as the basic frame of the entire structure. A cutting fluid recovery tank 2 is provided on the bottom inner side of the machine tool body 1. During machining, the CNC machine tool body 1 uses an internal water pump, delivery pipe, and nozzles to spray cutting fluid from the cutting fluid collection tank onto the workpiece, providing cooling and lubrication between the tool and the workpiece. Simultaneously, the cutting fluid recovery tank 2 collects cutting fluid flowing down from the operating table 4 and other locations, facilitating its flow into the cutting fluid storage tank inside the CNC machine tool body 1. Features present in existing technology are not described in detail, and the cutting fluid recovery tank 2 is frame-shaped. Safety doors 3 are provided on the left and right sides of the inner front of the CNC machine tool body 1, allowing operators to easily handle workpieces by opening or closing the safety doors 3. An operating table 4 is fixedly connected to the middle inner side of the CNC machine tool body 1, which is the main working area for machining.

[0028] Example 2: Figures 1 to 5 As shown, the operating platform 4 has sliding grooves 41 on both the front and rear sides. Sliding blocks are slidably connected to the left and right sides of the interior of each sliding groove 41. Protective plates 5 are fixedly connected to the outer surfaces of the sliding blocks. There are two protective plates 5, and they are U-shaped mirror images of each other. In use, the operator pushes the two protective plates 5, causing the sliding blocks to slide within the sliding grooves 41, effectively merging the two protective plates 5 into a single unit. A positioning hole 55 is provided on the upper front of the right protective plate 5, facilitating the use of the positioning rod 561. A semi-circular block 56 is movably connected to the upper front of the left protective plate 5. When the two protective plates 5 are combined, rotate the positioning rod 561 on the semicircular block 56 to align it with the positioning hole 55 on the right protective plate 5. Since the front end of the positioning rod 561 is fixedly connected to the circular block 562, and the outer surface of the circular block 562 is fitted with a spring 563, the spring 563 is in a stretched state. After the positioning rod 561 aligns with the positioning hole 55, it resets under the elastic force of the spring 563. The positioning rod 561 can be inserted into the positioning hole 55 to achieve the positioning and fixing of the two protective plates 5, preventing the left and right protective plates 5 from moving during the processing. In addition, the front and rear ends of the spring 563 are fixed to the surfaces of the semicircular block 56 and the circular block 562, respectively.

[0029] Each of the left and right protective plates 5 has a limiting groove 51 on its opposite side, and a clamping assembly is installed inside each limiting groove 51. The left and right clamping assemblies consist of two clamping blocks 52, a bidirectional threaded rod 53, and a handle 54. The front and rear clamping blocks 52 are slidably connected to the inside of the limiting groove 51. The outer surfaces of the left and right bidirectional threaded rods 53 are threaded through the inside of the two clamping blocks 52, and the front ends of the two bidirectional threaded rods 53 are welded to the handle. After placing the workpiece on the operating table 4, the operator can rotate the handle 54 to rotate the bidirectional threaded rod 53. Since the bidirectional threaded rod 53 is threaded to the two clamping blocks 52, during the rotation of the bidirectional threaded rod 53, the two clamping blocks 52 will move closer or further apart along the limiting groove 51, thereby clamping or releasing the workpiece. This securely fixes the workpiece on the operating table 4, ensuring the stability of the processing.

[0030] Example 3: Figures 1 to 5 As shown, the upper surface of the operating table 4 has an inner cavity 42. A frame-shaped baffle plate 43 is fixedly connected to the upper part of the inner wall of the inner cavity 42. The frame-shaped baffle plate 43 facilitates the placement of the plate 45 and serves as a barrier. The upper surface of the frame-shaped baffle plate 43 is provided with a plate 45. The upper surface of the plate 45 has a rectangular array of several circular openings 46. Cutting fluid and chips can fall into the inner cavity 42 through the circular openings 46 and enter the collection box 44. At the same time, the plate 45 facilitates the placement of the workpiece on the surface.

[0031] A collection box 44 is slidably connected to the lower inner wall of the inner cavity 42. The collection box 44 consists of a frame plate 441 and a filter screen 442. The filter screen 442 is fixedly connected to the lower inner side of the frame plate 441. Cutting fluid and debris falling into the inner cavity 42 will further fall into the collection box 44. The cutting fluid will be filtered out through the filter screen 442, while the debris will remain on the filter screen 442. The length of the frame plate 441 is greater than the length of the operating table 4, and a U-shaped handle is fixedly connected to the center of the front of the frame plate 441. The operator can pull the collection box 44 out of the operating table 4 by pulling the U-shaped handle to clean the collected debris.

[0032] An opening 401 is provided on the lower front of the operating table 4. The interior of the opening 401 is slidably connected to the outer surface of the frame plate 441, allowing the collection box 44 to be easily pulled out and inserted into the operating table 4. Drain ports 403 are provided on both the front and rear sides of the lower surface of the operating table 4, allowing the filtered cutting fluid to be discharged. A shim block 402 is fixedly connected to the center of the lower surface of the operating table 4. The shim block 402 elevates the operating table 4, providing sufficient space for the installation of the collection box 44 and the discharge of the cutting fluid. Furthermore, the shim block 402 is fixed to the inner side of the CNC machine tool body 1.

[0033] Working principle: In use, first place the workpiece on plate 45, then close the left and right protective plates 5 to form a single unit. Next, rotate the semicircular block 56 to the appropriate position. Due to the elasticity of the spring 563, the circular block 562 and the positioning rod 561 are pulled and moved, causing the positioning rod 561 to enter the positioning hole 55 for locking. Then, with the cooperation of the clamping assembly, the workpiece is clamped and limited. Finally, close the safety door 3 and start the CNC machine tool body 1 to process the workpiece. The left and right protective plates 5 prevent breakage. To prevent chip splashing, after processing is completed, the safety door 3 is opened, and the circular block 562 is pulled to move the positioning rod 561, causing the spring 563 to stretch. At the same time, the outer surface of the positioning rod 561 separates from the positioning hole 55. Then, the left and right protective plates 5 are moved to facilitate opening, and the clamping assembly is operated to release the workpiece for easy removal. Then, the worker uses a brush to clean the chips on the surface of the plate 45, so that the chips fall into the collection box 44 through the circular opening 46 and are collected. By pulling the collection box 44, the collection box 44 is moved out of the inner cavity 42, which facilitates the cleaning of the collected chips.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
