Specific implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation of the present invention.

[0019] Embodiment 1: As Figures 1-7 shown, the present invention provides a technical solution: a low-noise gear transmission box for a machine tool, including a bottom plate 1 and a mounting box 2. A clamping mechanism 3 is arranged inside the mounting box 2. The clamping mechanism 3 includes a gear transmission box 301, a mounting rod 302, a moving plate 303, a connecting plate 304, and a limiting plate 305. The bottom of the gear transmission box 301 is fixedly connected to the top of the mounting rod 302. The bottom of the moving plate 303 is slidably connected to the top of the first placing plate 401. The top of the moving plate 303 is fixedly connected to the bottom of the connecting plate 304. One side of the connecting plate 304 is fixedly connected to one end of the limiting plate 305. A limiting rod 306 is slidably connected to the inner wall of the mounting rod 302. One end of the limiting rod 306 is in pressing contact with a bearing plate 307. An anti-slip sleeve 308 is fixedly installed on the outer wall of the limiting rod 306 at the left position of the mounting rod 302.

[0020] A first moving groove is formed at the top of the first placing plate 401. The bottom of the moving plate 303 is slidably connected to the inner wall of the first moving groove. A first spring is fixedly installed between one side of the moving plate 303 and the inner wall of the first moving groove. Limiting grooves are formed on both sides of the mounting rod 302. The outer side of the limiting plate 305 is in pressing contact with the inner wall of the limiting groove. A limiting hole is formed on the outer side of the mounting rod 302. The outer wall of the limiting rod 306 is in pressing contact with the inner wall of the limiting hole, so that the gear transmission box can be fixedly installed conveniently and quickly.

[0021] The top of the bottom plate 1 is fixedly connected to the bottom of the installation box 2, and a movable door is installed on the front of the installation plate 2.

[0022] The operator opens the movable door installed on the front of the installation box 2, pulls the moving plate 303 to slide in the first moving groove, slides the moving plate 303 to squeeze the first spring, drives the connecting plate 304 to move through the sliding of the moving plate 303, drives the limiting plate 305 to move through the movement of the connecting plate 304. At this time, the installation rod 302 installed at the bottom of the gear transmission box 301 is inserted into the guide sleeve 604 and the installation box 2 in sequence, and contacts the inner wall of the placement groove on the top of the first placement plate 401. At this time, the limiting rod 306 is inserted into the installation hole on the installation rod 302 and is in extrusion contact with one side of the bearing plate 307. The anti-slip sleeve 308 installed on the limiting rod 306 can increase the friction force between the limiting rod 306 and the installation rod 302. At this time, the moving plate 303 is released, and the moving plate 303 is reset by the elastic force of the spring, so that the limiting plate 305 can be inserted into the limiting groove, and thus the gear transmission box 301 can be installed.

[0023] It realizes the fixed installation of the gear transmission box 301 quickly and conveniently, solves the problem that the gear transmission box 301 is fixed and installed on the machine tool by bolts, and avoids the inability to disassemble the gear transmission box 301 quickly and conveniently.

[0024] Embodiment 2: On the basis of Embodiment 1, as Figures 1-7 shown, the present invention provides a technical solution: The buffer mechanism 4 includes a first placement plate 401, a connecting rod 402, a fixing plate 403, and a damper 404. The bottom of the first placement plate 401 is fixedly connected to one end of the connecting rod 402. The outer wall of the connecting rod 402 is fixedly connected to the inner wall of the fixing plate 403. The bottom of the fixing plate 403 is fixedly connected to the top of the damper 404. The bottom of the damper 404 is fixedly connected to the inner wall of the installation box 2.

[0025] The shape of the connecting rod 402 is L-shaped. A second moving groove is opened on the inner wall of the installation box 2. One end of the connecting rod 402 is slidably connected to the inner wall of the second moving groove. A placement groove is opened on the top of the first placement plate 401. A second spring is fixedly installed between the bottom of the first placement plate 401 and the inner wall of the installation box 2. The number of the second springs is two, and the second springs are symmetrically distributed at the bottom of the first placement plate 401 respectively, so as to perform shock absorption and buffering when the gear transmission box 301 vibrates during operation and reduce noise.

[0026] When the gear transmission 301 vibrates during operation, the installation rod 302 is driven to move by the gear transmission 301. The movement of the installation rod 302 drives the movement of the first placement plate 401. The movement of the first placement plate 401 drives the connecting rod 402 to slide in the second movement groove. The movement of the connecting rod 402 drives the movement of the fixing plate 403. The movement of the fixing plate 403 squeezes the damper 404. As the first placement plate 401 moves, the second spring is squeezed, thereby enabling shock absorption and buffering.

[0027] It is realized that when the gear transmission 301 vibrates, shock absorption and buffering can be carried out, thereby protecting the gear transmission 301 and reducing the noise generated during operation.

One side of the second placement plate 504 is fixedly connected to one end of the auxiliary plate 505.

[0029] A third spring is fixedly installed between the bottom of the buffer plate 502 and the inner wall of the buffer box 501. The number of the third springs is two, and the third springs are symmetrically distributed at the bottom of the buffer plate 502 respectively. The shape of the second placement plate 504 is U-shaped, and the shape of the auxiliary plate 505 is L-shaped, thereby enabling shock absorption and buffering and better assisting the buffer mechanism 4 in shock absorption and buffering.

[0030] As the gear transmission 301 moves, it drives the movement of the second placement plate 504. The movement of the second placement plate 504 drives the movement of the buffer rod 503. The movement of the buffer rod 503 drives the buffer plate 502 to slide in the inner wall of the buffer box 501. The sliding of the buffer plate 502 squeezes the third spring, thereby enabling shock absorption and buffering, better assisting the buffer mechanism 4 in buffering, fully reducing noise, and better fixing the gear transmission 301 by installing the auxiliary plate 505.

[0031] It is realized that the gear transmission 301 can be better shock-absorbed and buffered, and the gear transmission 301 can be installed, thereby better protecting the gear transmission 301 and increasing the service life of the gear transmission 301.
