Detailed Implementation

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, a tool changing buffer mechanism for a tool changer magazine according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 The present invention provides an embodiment of a tool changing buffer mechanism for a tool changing magazine, comprising two clamping frames 1, a tool changing arm 2 fixedly installed between the two clamping frames 1, and a buffer assembly and an adjustable clamping assembly provided between the clamping frames 1 and the tool changing arm 2.

[0027] The buffer assembly includes several limiting blocks 301, several mounting grooves 302, a damping plunger 303, a buffer head 304, and a first return spring 305. The limiting blocks 301 are slidably connected to the inner side of the clamping frame 1. The mounting grooves 302 are formed inside the limiting blocks 301. The damping plunger 303 is slidably connected to the inner side of the mounting groove 302. One end of the buffer head 304 is fixedly connected to one end of the damping plunger 303. The first return spring 305 is located inside the mounting groove 302. The diameter of the damping plunger 303 matches the inner diameter of the mounting groove 302, and the damping plunger 303 slides with the mounting groove 302 to generate damping. One end of the first return spring 305 abuts against one end surface of the damping plunger 303, and the other end of the first return spring 305 abuts against one end surface of the inner side of the mounting groove 302.

[0028] It should be noted that by setting a damping plunger 303, a buffer head 304 and a first return spring 305 inside the limiting block 301, when the tool changing arm 2 drives the clamping frame 1 to move back and forth, when the limiting block 301 is engaged with the tool-retrieving groove of the tool holder, it will first touch the buffer head 304. The buffer head 304 retracts into the limiting block 301, and the first return spring 305 and the damping plunger 303 work together to buffer the impact, thereby avoiding a huge impact between the limiting block 301 and the tool holder of the tool head, reducing the wear on the tool holder of the tool head when retrieving the tool head, and extending the service life of the tool holder of the tool head.

[0029] Example 2

[0030] In some embodiments, such as Figure 1 , Figure 2 As shown, the adjustable clamping assembly includes two fixed seats 401, a support rod 402, a fixed head 403, a clamping roller 404, a support block 405, a second return spring 406, a first fixing bolt 407, and a second fixing bolt 408. The two fixed seats 401 are fixedly installed on one side of the tool changing arm 2. The support rod 402 is slidably connected between the two fixed seats 401. The fixed head 403 is sleeved on one end of the support rod 402. The clamping roller 404 is rotatably connected to one end of the fixed head 403. The support block 405 is fixedly connected to the middle of the support rod 402. The second return spring 406 is sleeved on one end of the support rod 402. On the outer wall of the end, the first fixing bolt 407 is threadedly connected to one side of the fixing head 403, and the second fixing bolt 408 is rotatably connected to one end of the limiting block 301. One end of the first fixing bolt 407 passes through the inner side of the fixing head 403 and abuts against one side surface of the support rod 402. The fixing head 403 is fixedly installed on the outer wall of one end of the support rod 402 by the setting of the first fixing bolt 407. One end of the second return spring 406 abuts against one side surface of one of the fixing seats 401, and the other end of the second return spring 406 abuts against one side surface of the support block 405. The second fixing bolt 408 is threadedly connected to the clamping frame 1.

[0031] The adjustable clamping assembly is equipped with a clamping roller 404, which works with the clamping frame 1 to form a structure larger than a semicircle. The tool changing principle of this structure is the same as that of the existing tool magazine tool changing mechanism. Since the tool holder of the existing tool head has a clamping groove, which is an inherent structure, the ends of multiple limit blocks 301 are stuck in the groove, supporting the tool holder, and working with the support roller 404 to form a support structure larger than a semicircle to clamp the tool.

[0032] It should be noted that by setting a fixed head 403 that can move back and forth, and a second fixed bolt 408 for adjusting the position of the limiting block 301, the extension of the limiting block 301 can be adjusted by rotating the second fixed bolt 408. Since one end of the second fixed bolt 408 is rotatably connected to one end of the limiting block 301, and the second fixed bolt 408 is threadedly connected to the clamping frame 1, the extension of the 301 inside the clamping frame 1 can be adjusted by using the second fixed bolt 408 to adjust the extension of each limiting block 301, so that the ring formed by multiple limiting blocks 301 can be enlarged or reduced to adapt to the diameter of the tool holder. At the same time, loosening the first fixed bolt 407 can adjust the position of the fixed head 403 to ensure that the clamping roller 404 can cooperate with the limiting block 301 to form a diameter larger than a semicircle in order to clamp the tool. The size of the clamping diameter can be changed to suit tool holders of different sizes of cutting heads, thus meeting market demands.

[0033] Working principle: During tool changing, the tool changing arm 2 drives the clamping frame 1 to move back and forth. When the limiting block 301 is engaged with the tool-retrieving groove of the tool holder, it will first touch the buffer head 304. The buffer head 304 retracts into the limiting block 301. The first return spring 305 and the damping plunger 303 work together to buffer the impact between the limiting block 301 and the tool holder, thereby reducing the wear on the tool holder when retrieving it and extending the service life of the tool holder. The extension of the limiting block 301 can be adjusted by rotating the second fixing bolt 408. At the same time, the position of the fixing head 403 can be adjusted by loosening the first fixing bolt 407, which can change the size of the clamping aperture and is suitable for tool holders of different sizes of tool heads to meet market demand.

[0034] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
