Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a tool turret for a CNC lathe with a tool protection structure. Background Technology

[0002] As a core piece of equipment in the field of modern machining, CNC lathes are widely used for high-precision and high-efficiency machining of various shafts, discs and complex rotating parts. In the machining process of CNC lathes, the cutting tools are usually mounted on the cutter head and directly participate in the cutting operation. Their working state directly affects the machining accuracy, surface quality and production efficiency. With the continuous improvement of automation, the service life and safety of cutting tools have received increasing attention.

[0003] Currently, in actual operation, traditional cutting tools are often exposed when not machining, lacking effective physical protection measures. This can lead to the exposing cutting tools being accidentally struck by the handling robot arm, fixture, or workpiece itself due to positioning deviation or motion interference during automatic loading / unloading or workpiece positioning. This can result in chipped cutting tips, broken cutting blades, or deformed tool holders, seriously affecting tool life and machining safety, and increasing maintenance costs and replacement frequency.

[0004] Therefore, there is an urgent need to provide a tool turret for CNC lathes with a tool protection structure. Utility Model Content

[0005] In order to overcome the shortcomings of existing CNC lathe tool turrets which lack effective protection when not machining, making the tools susceptible to external collisions, chip contamination and environmental corrosion, resulting in tool damage, shortened life and safety hazards, this utility model provides a CNC lathe tool turret with a tool protection structure.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a CNC lathe tool turret with a tool protection structure, comprising a machining table, a cylinder mounted on the upper part of the machining table, a tool turret body mounted on the movable rod of the cylinder, a motor mounted on the side of the machining table, a bidirectional lead screw rotatably mounted on the lower part of the machining table, the bidirectional lead screw being connected to the output shaft of the motor, a guide rod fixedly mounted on the lower part of the machining table, the guide rod being arranged parallel to the bidirectional lead screw, and symmetrically distributed protective shells slidingly mounted on the guide rod, the protective shells being threadedly connected to both ends of the bidirectional lead screw.

[0007] Preferably, the protective shell is provided with an elastic cushioning pad on the outside.

[0008] Preferably, an air pump is installed on the rear side of the processing table, the air pump outlet is connected to an air supply pipe, the air supply pipe is connected to an air jet head, the air jet head is arranged on both sides of the cutter head body and faces the cutter area, the air pump inlet is connected to an air delivery pipe, and the air delivery pipe is connected to a clean air source.

[0009] Preferably, a fixed frame is fixedly installed on one side of the processing area of ​​the processing table, a cleaning brush is slidably installed on the fixed frame, and a pull rod is installed on the top of the cleaning brush.

[0010] Preferably, the pull rod is fitted with an anti-slip rubber sleeve.

[0011] Preferably, the cylinder is fitted with a protective cover.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting an openable protective shell structure driven by a motor and bidirectional lead screw, it can automatically close in the non-machining state, completely enclosing the cutter head body and the cutter installed on it, effectively preventing the cutter from being damaged by external collisions, dust pollution or environmental factors in the non-machining state, thereby extending the service life of the cutter and improving the machining accuracy and operational safety.

[0013] 2. By setting up an air jet mechanism consisting of an air pump, air supply pipe, air jet head and air delivery pipe, the tool and tool head surface can be directionally blown before the protective shell is closed to remove residual debris and contaminants, ensuring that the tool is in a clean state for the next machining, and improving machining accuracy and surface quality stability.

[0014] 3. A sliding cleaning brush with a pull rod is installed on the side of the processing table to clean the processing area table surface manually or automatically, remove accumulated chips in time, avoid affecting the workpiece positioning accuracy and clamping reliability, and further improve processing consistency.

Detailed Implementation

[0021] 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.

[0022] Example 1: Please refer to Figures 1-3 A CNC lathe tool turret with a tool protection structure includes a machining table 1. A cylinder 2 is mounted on the upper part of the machining table 1. A protective cover 17 is fitted around the cylinder 2 to shield it from chips and coolant splashes, protecting it from contamination and damage, and extending its service life. The movable rod of the cylinder 2 is connected to the tool turret body 3, which can move up and down under the drive of the cylinder 2. A motor 4 is mounted on the left side of the machining table 1. A bidirectional lead screw 5 is rotatably mounted in the lower middle part of the machining table 1, and the bidirectional lead screw 5 is connected to the output shaft of the motor 4. A guide is fixedly mounted in the lower middle part of the machining table 1. The guide rod 6 is arranged parallel to the bidirectional lead screw 5. The guide rod 6 is slidably provided with symmetrically distributed protective shells 7. The two protective shells 7 are respectively threaded to the left and right ends of the bidirectional lead screw 5. When the drive motor 4 rotates forward and reverse, it drives the bidirectional lead screw 5 to rotate, thereby driving the two protective shells 7 to slide synchronously towards or away from each other along the guide rod 6, realizing the closed protection or open exposure of the cutter head body 3. The protective shell 7 is provided with an elastic buffer pad 8. The elastic buffer pad 8 is made of rubber material and is used to buffer collisions, prevent scratches on the cutter surface, and enhance the sealing performance in the closed state.

[0023] When using this device, the workpiece is first placed in the processing area of ​​the processing table 1. Then, the motor 4 is started, and the motor 4 drives the bidirectional lead screw 5 to rotate, causing the two protective shells 7 to slide open to both sides, exposing the cutter head body 3 located in the middle. Next, the cylinder 2 is started, and its moving rod drives the cutter head body 3 to move downward to cut the workpiece. After processing, the cylinder 2 drives the cutter head body 3 to rise back to the initial position. Then, the motor 4 rotates in the opposite direction, driving the bidirectional lead screw 5 to rotate in the opposite direction, causing the two protective shells 7 to slide and close from both sides to the middle, surrounding the cutter head body 3 inside. This achieves physical protection of the cutting tool, preventing damage to the tool caused by external collisions, dust contamination, or environmental factors when not processing, thereby extending the tool's service life and improving processing accuracy and operational safety.

[0024] Example 2: Based on Example 1, please refer to... Figure 4 An air pump 9 is installed on the rear side of the processing table 1. The air outlet of the air pump 9 is connected to an air supply pipe 10. Two jet nozzles 11 are connected to the air supply pipe 10. The jet nozzles 11 are symmetrically arranged on the left and right sides of the cutter head body 3 and facing the tool area. They are used to directionally blow the surface of the cutter head body 3 and the cutting edge area of ​​the tool to remove residual metal chips, dust and coolant residue. The air inlet of the air pump 9 is connected to an air supply pipe 12, which is connected to a clean air source.

[0025] After the cylinder 2 drives the cutter head body 3 to rise vertically back to the initial safe position and before the protective shell 7 closes, the air pump 9 is turned on to input clean air into the air supply pipe 10, so that the jet nozzle 11 sprays out a high-speed airflow for a short time to blow away the chips, dust and other contaminants attached to the tool surface and the cutter head, improve the reliability and machining accuracy of the tool in the next use, and at the same time, prevent contaminants from being sealed in the protective shell 7 in the closed state, causing secondary pollution or corrosion.

[0026] Please see Figure 5 A fixed frame 13 is fixedly installed on the rear side of the processing area of ​​the processing table 1. A cleaning brush 14 is slidably installed on the fixed frame 13. A pull rod 15 is installed on the top of the cleaning brush 14. By pulling the pull rod 15, the cleaning brush 14 is driven to slide along the processing area of ​​the processing table 1 to remove residual debris. The pull rod 15 is covered with an anti-slip rubber sleeve 16 to improve the operating feel and prevent slippage.

[0027] After the workpiece is processed and unloaded, the operator pulls the lever 15, which drives the cleaning brush 14 to move horizontally back and forth along the fixed frame 13. The brush bristles sweep across the processing area, concentrating and pushing out the debris to achieve rapid cleaning. After cleaning is completed, the cleaning brush 14 is reset, the lever 15 returns to its position, and the equipment enters the next processing cycle.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
