Description

Technical Field

[0001] This utility model relates to the field of internal groove grinding technology, and in particular to a tungsten steel internal groove grinding device for deep hole gun drilling. Background Technology

[0002] With the rapid development of high-precision manufacturing, deep hole machining technology has been widely used in aerospace, automotive manufacturing, and precision equipment production. In deep hole machining, the grinding accuracy of the tungsten carbide inner groove is crucial to the quality of the final product. Traditional deep hole gun drilling methods face the problem of cleaning tungsten carbide debris during the grinding process. If this debris is not removed in time, it will accumulate on the workpiece surface or around the grinding tool, affecting the contact accuracy between the grinding head and the workpiece, and thus leading to machining errors.

[0003] Existing tungsten carbide inner groove grinding devices mostly employ traditional mechanical structures, typically using a fixed grinding head and manual or automatic feeding devices. During the grinding process, the grinding head rotates along the workpiece surface, removing the tungsten carbide inner groove material from the workpiece surface through mechanical cutting principles. However, when these traditional devices are in operation, the grinding debris generated is distributed on the surface of the workpiece or on the surrounding tools.

[0004] Existing technologies for grinding tungsten carbide inner grooves cannot effectively remove the generated debris, especially since tungsten carbide debris tends to accumulate on the workpiece surface or around the grinding tool, severely affecting the contact accuracy between the grinding head and the workpiece. This problem not only reduces processing accuracy and efficiency but also causes irregular grinding marks on the workpiece surface, thus affecting the quality of the final product. To address this issue, a tungsten carbide inner groove grinding device for deep hole gun drilling is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a tungsten steel inner groove grinding device for deep hole gun drilling, which aims to improve the problem in the prior art where tungsten steel debris, if not cleaned in time during the grinding process, will accumulate on the surface of the workpiece or around the grinding tool, affecting the contact accuracy between the grinding head and the workpiece.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A tungsten steel inner groove grinding device for deep hole gun drilling includes a bracket, a motor pulley drive structure fixedly connected to the bottom of the bracket, a chuck fixedly connected to the output end of the motor pulley drive structure, a support plate fixedly connected to the top of the bracket, a first slide rail fixedly connected to the top of the bracket, a second motor screw drive structure fixedly connected to the side wall of the bracket, a sliding plate threadedly connected to the outer wall of the second motor screw drive structure, a tool holder fixedly connected to the top of the sliding plate, a tool holder slidably connected to the outer wall of the first slide rail at its bottom, a drill bit disposed inside the tool holder, and a cleaning component disposed inside the bracket.

[0008] As a further description of the above technical solution: The top of the support plate is fixedly connected to a first motor lead screw drive structure, and the outer wall of the first motor lead screw drive structure is threadedly connected to a connecting frame.

[0009] As a further description of the above technical solution: A first connecting block is fixedly connected to the bottom of the connecting frame, and a first slider is fixedly connected to the bottom of the connecting frame.

[0014] This utility model has the following beneficial effects: 1. In this utility model, pulling the handle moves the filter plate on one side, and the filter plate slides inside the bracket. Then, the debris on the top of the filter plate is scraped off by the side wall of the bracket, and the debris falls into the inside of the material carrier for unified collection. This achieves the effect of convenient debris cleaning and solves the problem that if tungsten steel debris is not cleaned in time during the grinding process, it will accumulate on the surface of the workpiece or around the grinding tool, affecting the contact accuracy between the grinding head and the workpiece.

[0015] 2. In this utility model, the first connecting plate is driven to move by a hydraulic cylinder. The movement of the first connecting plate moves the moving plate, and at the same time, the movement of the moving plate moves the first slider at the top to slide on the outer wall of the second slide rail. Then, during the process of the moving plate being subjected to force, the connecting rod and the rotating plate are driven to rotate. The rotating plate rotates on the outer wall of the rotating seat, which achieves the effect of auxiliary support for the workpiece. This solves the problem that without an auxiliary support system, the workpiece will move during the processing due to vibration or uneven feed force, resulting in a decrease in processing accuracy. This improves the practicality of the tungsten carbide inner groove grinding device. Attached Figure Description

[0021] Working principle: During processing, the motor pulley drive structure 4 drives the chuck 5 to rotate, thereby driving the workpiece to rotate. At the same time, the second motor screw drive structure 9 drives the sliding plate 10 to move along the first slide rail 11 through thread transmission, so that the drill bit 6 in the tool holder 8 approaches the workpiece and performs grinding. The first motor screw drive structure 7 drives the connecting frame 18 to adjust its position. When the hydraulic cylinder 20 at the bottom of the connecting frame 18 extends or retracts, it pushes the moving plate 24 through the first connecting plate 21. The moving plate 24 slides on the second slide rail 23 with the help of the first slider 22. At the same time, the connecting rod 28 drives the rotating plate 27 to rotate around the rotating seat 26, so that the semi-circular bearing 25 on the side wall of the moving plate 24 fits against the workpiece, realizing stable support for workpieces of different specifications, ensuring the rigidity of the workpiece during grinding, and reducing the impact of vibration on accuracy. The grinding debris falls onto the filter plate 12. When cleaning is required, pull the handle 13 to slide the filter plate 12 within the bracket 1. At this time, the side wall of the bracket 1 scrapes off the debris from the filter plate 12, and the debris falls into the material cart 2 below for collection. When the filter plate 12 slides, the locking block 14 on its side wall presses against the locking plate 16. The locking plate 16 compresses the spring 17 and slides within the hollow plate 15 through the second slider 29. After releasing the handle 13, the spring 17 returns to its original position and pushes the locking plate 16 to lock the locking block 14, thus fixing the filter plate 12. This ensures the stability of the filter plate 12 during processing, improves the convenience of debris cleaning, and prevents debris accumulation from affecting the grinding accuracy.
