Abstract
Description
Technical Field
[0001] This utility model belongs to the field of parts drilling technology, specifically relating to a drilling device for machining mechanical parts. Background Technology
[0002] Mechanical parts are the basic components that make up mechanical systems or equipment. During their processing, drilling is often required. Currently, the industry generally uses special drilling equipment for this type of operation.
[0003] Existing equipment typically uses clamping and fixing of regular parts to complete drilling by rotating the drill bit at high speed. However, when drilling multiple points on the annular surface of a cylindrical workpiece, the workpiece orientation needs to be frequently adjusted to achieve uniform circumferential hole distribution. This repeated positioning operation not only seriously affects processing efficiency and accuracy control, but also leads to a reduction in work efficiency. Utility Model Content
[0004] In view of this, the present invention provides a drilling device for machining mechanical parts. Through the coordinated operation of the lifting component, the drilling mechanism, the synchronous drive component and the rotating component, it can directly drill synchronously in the circumferential direction when drilling cylindrical mechanical parts, without the need to adjust and fix the parts back and forth, which greatly improves work efficiency and machining accuracy.
[0005] To solve the above-mentioned technical problems, this utility model provides a drilling device for machining mechanical parts, including a worktable and a lifting assembly disposed on its upper end. The upper part of the inner cavity of the lifting assembly is provided with a drilling mechanism. The drilling mechanism includes fixed rods symmetrically disposed at both ends of the upper part of the inner cavity of the lifting assembly. A fixed cover is provided at the lower end between the two fixed rods. Several rotating cylinders are rotatably connected to the outer arc surface of the fixed cover. Guide rods are slidably connected inside each rotating cylinder. Drill bits are provided at the inner ends of the guide rods. A chuck is provided at the upper end of the worktable. A synchronous drive assembly for synchronously driving the guide rods to move centripetally is also provided between the two fixed rods. A rotating assembly for synchronously driving the rotating cylinders to rotate is also provided on the fixed cover. That is, when drilling cylindrical mechanical parts, circumferential synchronous drilling can be performed directly without adjusting the fixed parts back and forth, which greatly improves work efficiency and machining accuracy.
[0006] The synchronous drive assembly includes a sliding cover that is slidably connected between two fixed rods. The cross-section of the sliding cover is an inverted V-shaped structure. The inner arc surface of the guide groove is provided with several guide blocks. The inner end of each guide block is rotatably connected to the outer end of the adjacent guide rod on the same side, thereby forcing multiple guide rods to move synchronously towards the center.
[0007] The rotating assembly includes a gear ring 1 disposed on the inner end of the outer arc surface of the rotating cylinder, and a gear ring 2 rotatably connected to the upper end of the inner cavity of the rotating cylinder, which serves as a fast transmission mechanism.
[0008] The rotating assembly also includes a gear three rotatably connected to the upper edge of the inner cavity of the rotating cylinder, a gear ring four on the outer arc surface of the gear ring two, a motor at the upper end of the rotating cylinder, and the output shaft of the motor fixedly connected to the upper end of the gear three. The gear three and the gear ring four mesh with each other, thus achieving synchronous and rapid driving.
[0009] The lifting assembly includes a sliding frame slidably connected to the worktable. The lower end of the worktable is provided with an electric push rod. The telescopic end of the electric push rod is fixedly connected to the lower end of the sliding frame. Two fixed rods are symmetrically distributed at both ends of the upper part of the inner cavity of the sliding frame, which adjusts the height position of the drilling mechanism.
[0010] An electric push rod 2 is provided on one side of the upper end of the sliding frame. The telescopic end of the electric push rod 2 is fixedly connected to the upper end of the sliding cover, that is, the sliding cover provides the driving source.
[0011] The inner cavity of the rotating cylinder is equipped with a protective cover, and each protective cover has a rotating hole that matches each rotating cylinder, which can prevent the waste generated by drilling from affecting the operation of its internal structure.
[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0013] 1. The cylindrical mechanical part is inserted sequentially into the sliding cover and fixed cover through the opening in the middle of the upper end of the sliding frame. Then, the cylindrical mechanical part to be processed is fixed by the chuck on the worktable. Subsequently, according to the position of the part to be processed, the lifting component controls the height of the sliding frame and its auxiliary mechanism on the worktable, thereby adjusting the height position of the drilling mechanism to meet the needs of drilling at different heights. After the height adjustment is completed, the rotating component drives the rotating cylinder to rotate around its own axis. When the rotating cylinder rotates, it drives the drill bit to rotate synchronously. At the same time, it pushes the sliding cover down. When the sliding cover moves down, the guide block slides relative to the guide groove. As the position of the guide groove and the guide block changes, multiple guide rods are forced to move synchronously towards the center, so that the drill bit at the end of the guide rod gradually approaches the surface of the workpiece for drilling. When drilling cylindrical mechanical parts, circumferential synchronous drilling can be performed directly without adjusting and fixing the parts back and forth, which greatly improves work efficiency and processing accuracy.
[0014] 2. The sliding cover moves down. When the sliding cover moves down, the guide block slides relative to the guide groove. As the position of the guide groove and the guide block changes, multiple guide rods are forced to move synchronously towards the center.
[0015] 3. When the motor starts, the output shaft of the motor rotates, driving gear three to rotate. Gear three meshes with gear ring four, thereby driving gear ring two to rotate. When gear ring two rotates, it drives the rotating cylinder to rotate around its own axis through gear ring one, which meshes with it. When the rotating cylinder rotates, it drives the drill bit to rotate synchronously, thus playing a role in synchronous and rapid drive. Attached Figure Description

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0022] This embodiment provides a drilling device for machining mechanical parts, such as... Figure 1-4 As shown: It includes a worktable 100 and a lifting assembly disposed on its upper end. The upper part of the inner cavity of the lifting assembly is provided with a drilling mechanism. The drilling mechanism includes fixed rods 200 symmetrically disposed at both ends of the upper part of the inner cavity of the lifting assembly. A fixed cover 201 is provided at the lower end between the two fixed rods 200. Several rotating cylinders 202 are rotatably connected to the outer arc surface of the fixed cover 201. Guide rods 203 are slidably connected inside each rotating cylinder 202. Drill bits 204 are provided at the inner end of each guide rod 203. A chuck 700 is provided at the upper end of the worktable 100. A synchronous drive assembly for synchronously driving the guide rods 203 to move centripetally is also provided between the two fixed rods 200. A rotating assembly for synchronously driving the rotating cylinders 202 to rotate is also provided on the fixed cover 201.
[0023] First, the cylindrical mechanical part is inserted sequentially into the sliding cover 300 and the fixed cover 201 through the opening at the middle of the upper end of the sliding frame 500. Then, the cylindrical mechanical part to be processed is fixed by the chuck 700 on the worktable 100. Subsequently, according to the position of the part to be processed, the lifting component controls the height of the sliding frame 500 and its auxiliary mechanisms on the worktable 100, thereby adjusting the height position of the drilling mechanism to meet the needs of drilling at different heights. After the height adjustment is completed, the rotating component drives the rotating cylinder 202 to rotate around its own axis. When 02 rotates, it drives the drill bit 204 to rotate synchronously. At the same time, it pushes the sliding cover 300 to move down. When the sliding cover 300 moves down, the guide block 302 slides relative to the guide groove 301. As the position of the guide groove 301 and the guide block 302 changes, multiple guide rods 203 are forced to move synchronously towards the center, so that the drill bit 204 at the end of the guide rod 203 gradually approaches the workpiece surface to perform drilling operations. When drilling cylindrical mechanical parts, it can directly drill synchronously in the circumference without adjusting and fixing parts back and forth, which greatly improves work efficiency and processing accuracy.
[0024] like Figure 1-4 As shown, the synchronous drive assembly includes a sliding cover 300 slidably connected between two fixed rods 200. The cross-section of the sliding cover 300 is an inverted V-shaped structure. The inner arc surface of the guide groove 301 is provided with a number of guide blocks 302. The inner end of each guide block 302 is rotatably connected to the outer end of the adjacent guide rod 203 on the same side.
[0025] As the sliding cover 300 moves downward, the guide block 302 slides relative to the guide groove 301. As the positions of the guide groove 301 and the guide block 302 change, multiple guide rods 203 are forced to move synchronously towards the center.
[0026] like Figure 1-4 As shown, the rotating assembly includes a first gear ring 400 disposed on the inner end of the outer arc surface of the rotating cylinder 202, a second gear ring 401 rotatably connected to the upper end of the inner cavity of the rotating cylinder 202, and a third gear 402 rotatably connected to the upper edge of the inner cavity of the rotating cylinder 202. A fourth gear ring 403 is disposed on the outer arc surface of the second gear ring 401. A motor 404 is disposed at the upper end of the rotating cylinder 202. The output shaft of the motor 404 is fixedly connected to the upper end of the third gear 402, and the third gear 402 meshes with the fourth gear ring 403.
[0027] When motor 404 starts, the output shaft of motor 404 rotates, driving gear three 402 to rotate. Gear three 402 meshes with gear ring four 403, thereby driving gear ring two 401 to rotate. When gear ring two 401 rotates, it drives rotating cylinder 202 to rotate around its own axis through gear ring one 400 meshing with it. When rotating cylinder 202 rotates, it drives drill bit 204 to rotate synchronously, achieving the function of synchronous and rapid drive.
[0028] like Figure 1-3 As shown, the lifting assembly includes a sliding frame 500 slidably connected to the worktable 100. The lower end of the worktable 100 is provided with an electric push rod 501. The telescopic end of the electric push rod 501 is fixedly connected to the lower end of the sliding frame 500. Two fixed rods 200 are symmetrically distributed at both ends of the upper part of the inner cavity of the sliding frame 500.
[0029] When the electric push rod 501 is activated, its telescopic end extends or retracts to control the height of the sliding frame 500 and its auxiliary mechanisms on the worktable 100, thereby adjusting the height position of the drilling mechanism.
[0030] like Figure 1-2 As shown, an electric push rod 600 is provided on one side of the upper end of the sliding frame 500. The telescopic end of the electric push rod 600 is fixedly connected to the upper end of the sliding cover 300. The electric push rod 600 drives the sliding cover 300 to move up or down, providing a driving source for the sliding cover 300.
[0031] like Figure 2-4 As shown, the inner cavity of the rotating cylinder 202 is provided with a protective cover 800. Each protective cover 800 is provided with a rotating hole that matches each rotating cylinder 202, which can prevent the waste generated by drilling from affecting the operation of its internal structure.
[0032] The working principle of the drilling device for machining mechanical parts provided by this utility model is as follows: First, the cylindrical mechanical part is inserted into the sliding cover 300 and the fixed cover 201 through the opening in the middle of the upper end of the sliding frame 500. Then, the cylindrical mechanical part to be processed is fixed by the chuck 700 on the worktable 100. Subsequently, according to the position to be processed of the part, the electric push rod 501 is started, and its extension or retraction end controls the height of the sliding frame 500 and its auxiliary mechanism on the worktable 100, thereby adjusting the height position of the drilling mechanism to meet the needs of drilling at different heights. After the height adjustment is completed, the motor 404 is started, and the output shaft of the motor 404 rotates to drive the gear 402 to rotate. The gear 402 meshes with the gear ring 403, thereby driving the gear ring 401 to rotate. When the gear ring 401 rotates, it meshes with the gear ring 402. The gear ring 400 drives the rotating cylinder 202 to rotate around its own axis. When the rotating cylinder 202 rotates, it drives the drill bit 204 to rotate synchronously. At the same time, the electric push rod 600 is activated, and its telescopic end extends to push the sliding cover 300 downward. When the sliding cover 300 moves downward, the guide block 302 slides relative to the guide groove 301. As the position of the guide groove 301 and the guide block 302 changes, multiple guide rods 203 are forced to move synchronously towards the center, so that the drill bit 204 at the end of the guide rod 203 gradually approaches the workpiece surface to perform drilling operations. When drilling cylindrical mechanical parts, it can directly drill synchronously in the circumference without adjusting and fixing parts back and forth, which greatly improves work efficiency and processing accuracy. The protective cover 800 is set in the inner cavity of the rotating cylinder 202 to protect the internal structure and cooperates with the rotating cylinder 202 through the rotating hole to ensure the stable operation of the device.
[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
