A mobile extension type tool magazine device

Abstract

This invention relates to the field of machine tool equipment technology and discloses a mobile expandable tool magazine device, including a positioning plate, a sealing plate, and several tool bodies mounted on the positioning plate. The tool body switching method of this invention is achieved through a flipping groove on the sealing plate, eliminating the need for a drive source. Therefore, no additional drive source is required when expanding the tool bodies, reducing the cost of expanding the tool bodies. Furthermore, during subsequent cleaning of the tool bodies, the cleaning plate is in a flipping motion. During this flipping process, the cleaning plate slides vertically on the tool bodies, lifting spiral-shaped debris upwards and separating it from the tool bodies. Meanwhile, the brushes on the cleaning plate are essentially sliding horizontally on the tool bodies, allowing for the horizontal sliding cleaning of smaller debris, ultimately improving the cleaning effect.

Description

Technical Field

[0001] This invention belongs to the field of machine tool equipment technology, and more specifically, relates to a mobile expandable tool magazine device. Background Technology

[0002] With the rapid development of modern manufacturing, the pursuit of high precision, high efficiency, and complex processes in machining has reached unprecedented heights. Against this backdrop, machine tools, as core tools in manufacturing, directly determine product quality and production efficiency based on their performance. The tool magazine, as a key component of a machine tool, undertakes the important task of storing and quickly changing tools; its performance has a crucial impact on the overall machining efficiency of the machine tool.

[0003] Each tool in the existing tool magazine is equipped with a specific drive source, which allows the tool to rotate after moving to a designated position, switching the tool to machining mode. However, this method requires the addition of tools with drive sources when expanding the tool range later, increasing costs. Furthermore, during metal cutting and other machining processes, the tools generate a large amount of debris, especially spiral debris. This debris easily becomes entangled on the tool surface. Existing tool magazines rely solely on simple planar rolling cleaning during tool retrieval, which is insufficient to effectively remove these tightly entangled spiral debris. Ultimately, the debris may accumulate inside the tool magazine, causing wear and damage to critical components such as the tool magazine's transmission mechanism and positioning device, thereby affecting the normal operation and service life of the tool magazine.

[0004] In view of this, the present invention is proposed. Summary of the Invention

A plurality of pairs of notches are opened on the surface of the reversing ring, and the plurality of pairs of notches correspond to the tool body.

[0014] In a preferred embodiment of the present invention, a rocker arm is mounted on the guide shaft. The rocker arm is in an inclined state. A strip groove is formed on the rocker arm. A slide rod is slidably mounted on the strip groove. The diameter of the slide rod is adapted to the width of the strip groove. A U-shaped frame is mounted at the end of the slide rod. The U-shaped frame is horizontally slidably connected to the connecting frame.

[0015] In a preferred embodiment of the present invention, the bottom of the connecting frame is provided with an inner groove, a guide rod is horizontally installed inside the inner groove, a slide block is slidably installed on the guide rod, a guide spring is sleeved on the guide rod, one end of the guide spring is engaged in the inner groove, and the other end of the guide spring is engaged in the slide block. The bottom of the slide block and the U-shaped frame are connected to each other. A synchronous slider is installed at the bottom of the U-shaped frame. The synchronous slider is slidably installed in an annular groove, and the annular groove is opened on the sealing plate.

[0016] In a preferred embodiment of the present invention, a cleaning groove is provided on the cleaning plate and is located on both sides of the tool body. A brush is installed on the side wall of the cleaning groove and is in contact with the side wall of the tool body.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The tool body switching method of the present invention is carried out through the flipping groove on the sealing plate, which does not require a driving source. Therefore, no additional driving source is needed when expanding the tool body, thereby reducing the cost of expanding the tool body.

Meanwhile, the brush on the cleaning plate is equivalent to the tool body sliding horizontally. Thus, the brush can horizontally slide and clean smaller debris, which ultimately improves the cleaning effect.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0038] Example 1:

[0039] like Figures 1 to 10 As shown, a mobile expandable tool magazine device includes a positioning plate 12, a sealing plate 13, and a plurality of tool bodies 2 mounted on the positioning plate 12.

[0040] A positioning and flipping assembly is installed on the positioning plate 12. The positioning and flipping assembly includes an annular groove 25 and a flipping groove 251 is installed on the annular groove 25. The flipping groove 251 is used to push the rocker arm 23 installed on the tool body 2 to rotate, thereby pushing the tool body 2 to rotate around the side wall of the positioning plate 12 and rotating the tool body 2 to the machining station.

[0041] A self-cleaning assembly is installed on the positioning plate 12. The self-cleaning assembly includes a cleaning plate 3 and a synchronizing ring 34 that are rotatably connected. A brush 311 is installed on the side wall of the cleaning plate 3. A pressure plate 33 is installed on the cleaning plate 3. A pressing protrusion 341 is installed at the bottom of the synchronizing ring 34. The pressing protrusion 341 is used to press the cleaning plate 3 to deflect and drive the brush 311 to slide horizontally and move vertically on the side wall of the tool body 2. A drive assembly for driving the positioning and flipping assembly and the self-cleaning assembly to rotate is also installed on the positioning plate 12.

[0042] like Figures 1 to 10 As shown in the specific embodiment, L-shaped connecting seats 14 are installed on the side walls of the sealing plate 13 and the positioning plate 12. A base 1 is located at the bottom of the L-shaped connecting seat 14, and a pair of limiting guide rails 11 fixed to the machine tool are slidably installed on the base 1. The limiting guide rails 11 ensure that the sealing plate 13 and the positioning plate 12 can slide horizontally. Reinforcing ribs 141 are installed at the bends of the L-shaped connecting seat 14. The reinforcing ribs 141 are triangular, and their structural strength is improved. An air intake 131 is installed on the sealing plate 13, and the air intake 131 is connected to a dust collection system. The dust collection system can adsorb the cleaned debris, thus completing the debris cleaning operation. The dust collection system is existing technology and is not shown in the figure; its working principle will not be described further here.

[0043] Example 2:

[0044] The difference between Embodiment 1 and this embodiment is that: Figures 1 to 10As shown, the drive assembly includes a drive motor 22, the housing of which is mounted on the back of the positioning plate 12. A synchronous shaft 221 is mounted on the output shaft of the drive motor 22, and the synchronous shaft 221 movably passes through the center of the sealing plate 13 and the positioning plate 12. Several pairs of connecting brackets 212 are mounted on the synchronous shaft 221, and each connecting bracket 212 corresponds to a corresponding tool body 2. The drive motor 22 drives the synchronous shaft 221 to rotate counterclockwise, which in turn drives the synchronously connected connecting brackets 212 to rotate, and the connecting brackets 212 drive the corresponding tool body 2 to rotate synchronously.

[0045] like Figures 1 to 10 As shown, in a specific embodiment, a synchronization bracket 213 is installed on the side wall of the connecting frame 212, and a reversing ring 15 is installed at the end of the synchronization bracket 213. One end of the reversing ring 15 is slidably connected to the guide groove 121 opened on the side wall of the positioning plate 12, and the other end of the reversing ring 15 is slidably connected to the side wall of the sealing plate 13. Several pairs of notches 151 are opened on the surface of the reversing ring 15, and the several pairs of notches 151 correspond to the tool body 2.

[0046] like Figures 1 to 10 As shown, furthermore, each tool body 2 has a mounting base 21 installed on its side wall near the center of rotation. A guide shaft 231 is fixedly mounted on the mounting base 21, and a positioning seat 211 is rotatably mounted on the guide shaft 231. The bottom of the positioning seat 211 is connected to the connecting frame 212. A rocker arm 23 is mounted on the guide shaft 231. The rocker arm 23 is in an inclined state. A strip groove 232 is opened on the rocker arm 23. A slide rod 241 is slidably mounted on the strip groove 232. The diameter of the slide rod 241 is adapted to the width of the strip groove 232. A U-shaped frame 24 is installed at the end of the slide rod 241. The U-shaped frame 24 is horizontally slidably connected to the connecting frame 212. When the U-shaped frame 24 slides outward, the slide bar 241 on the U-shaped frame 24 slides on the strip groove 232 of the rocker arm 23, and can push the rocker arm 23 with the strip groove 232 to swing. At this time, the rocker arm 23 drives the guide shaft 231 to rotate in the positioning seat 211, and the mounting seat 21 on the guide shaft 231 rotates synchronously. The mounting seat 21 drives the tool body 2 to rotate. At this time, the tool body 2 can rotate 90 degrees, thereby rotating the tool body 2 out from the reversing ring 15, which facilitates the subsequent processing operation.

[0047] like Figures 1 to 10As shown, the bottom of the connecting frame 212 is provided with an inner groove 245. A guide rod 243 is horizontally installed inside the inner groove 245. A slide block 242 is slidably installed on the guide rod 243. A guide spring 244 is sleeved on the guide rod 243. One end of the guide spring 244 is engaged in the inner groove 245, and the other end of the guide spring 244 is engaged in the slide block 242. The bottom of the slide block 242 is connected to the U-shaped frame 24. A synchronous slider 252 is installed at the bottom of the U-shaped frame 24. The synchronous slider 252 is slidably installed in the annular groove 25, and the annular groove 25 is opened on the sealing plate 13. When the synchronous slider 252 at the bottom of the synchronous bracket 213 can slide along the annular groove 25 onto the flip groove 251, the flip groove 251 drives the entire synchronous slider 252 to slide outward along the connecting frame 212. The U-shaped frame 24 on the synchronous slider 252 slides synchronously, and the slide block 242 on the U-shaped frame 24 slides on the guide rod 243. At this time, the slide block 242 compresses the guide spring 244, and the compressed guide spring 244 facilitates later reset.

[0048] Example 3:

[0049] The difference between Embodiment 2 and this embodiment is that: Figures 1 to 10 As shown, a cleaning groove 31 is provided on the cleaning plate 3, and the cleaning groove 31 is located on both sides of the tool body 2. A brush 311 is installed on the side wall of the cleaning groove 31, and the brush 311 is in contact with the side wall of the tool body 2. A scraper 32 is horizontally slidably installed on the cleaning plate 3, and the arc surface of the scraper 32 is in contact with the tool body 2. A sliding plate 321 is installed on the side wall of the scraper 32. A limit rod 322 is movably installed through the sliding plate 321. Limit seats 324 are installed at both ends of the limit rod 322. The limit seats 324 are installed on the cleaning plate 3. A limit spring 323 is sleeved on the limit rod 322. The two ends of the limit spring 323 are respectively engaged with the side wall of the sliding plate 321 and the limit seat 324. When the tool body 2 slides outward in the cleaning groove 31, the limiting spring 323 drives the slide plate 321 to have an outward sliding force, which causes the slide plate 321 to slide on the limiting rod 322. The scraper 32 connected to the side wall of the slide plate 321 is attached to the side wall of the tool body 2. The scraper 32 is equivalent to the tool body 2 sliding vertically. Finally, the long spiral debris wrapped on the tool body 2 can be pushed upward, so that the debris and the tool body 2 are completely separated.

[0050] like Figures 1 to 10As shown, in a specific embodiment, a retaining shaft 332 is fixedly installed at the rotation center of the cleaning plate 3. A support frame 331 is rotatably installed on the retaining shaft 332 and is mounted on the drive assembly. A pressure plate 33 is installed at the end of the retaining shaft 332, and a torsion spring 333 is sleeved on the retaining shaft 332. One end of the torsion spring 333 is engaged with the support frame 331, and the other end is engaged with the side wall of the pressure plate 33. When the cleaning plate 3 and the pressure plate 33 slide to the extrusion protrusion 341 on the synchronous ring 34, the extrusion protrusion 341 presses and rotates the pressure plate 33 through the extrusion action. The retaining shaft 332 on the pressure plate 33 rotates on the support frame 331, and the torsion spring 333 between the support frame 331 and the retaining shaft 332 twists synchronously. The torsion spring 333 facilitates subsequent reset operations.

[0051] like Figures 1 to 10 As shown, a mounting plate 342 is further installed at the bottom of the synchronization ring 34. The mounting plate 342 is connected to the sealing plate 13, and a locking bolt is screwed between them. The lower surface of the synchronization ring 34 is in contact with the pressure plate 33. The extrusion protrusion 341 and the flip groove 251 are not located in the same position. The mounting plate 342 facilitates the installation of the synchronization ring 34.

[0052] The implementation principle of the mobile expandable tool magazine device of the present invention is as follows:

[0053] When changing tools in the tool magazine, the operator can start the drive motor 22, which drives the synchronous shaft 221 to rotate counterclockwise. Figure 4 Based on this, the synchronous shaft 221 can drive the synchronously connected connecting frame 212 to rotate, and the positioning seat 211 and mounting seat 21 on the connecting frame 212 drive the tool body 2 to rotate synchronously. Furthermore, the synchronous bracket 213 on the connecting frame 212 drives the reversing ring 15 to rotate synchronously, so that the notch 151 on the reversing ring 15 and the tool body 2 correspond to each other.

[0054] During the sliding process described above, when the synchronous slider 252 at the bottom of the synchronous bracket 213 can slide along the annular groove 25 onto the flip groove 251, the flip groove 251 drives the entire synchronous slider 252 to slide outward along the connecting frame 212. The U-shaped frame 24 on the synchronous slider 252 slides synchronously, and the slide block 242 on the U-shaped frame 24 slides on the guide rod 243. At this time, the slide block 242 compresses the guide spring 244, and the compressed guide spring 244 facilitates subsequent reset.

[0055] When the U-shaped frame 24 slides outward, the slide bar 241 on the U-shaped frame 24 slides on the strip groove 232 of the rocker arm 23, and can push the rocker arm 23 with the strip groove 232 to swing. At this time, the rocker arm 23 drives the guide shaft 231 to rotate in the positioning seat 211, and the mounting seat 21 on the guide shaft 231 rotates synchronously. The mounting seat 21 drives the tool body 2 to rotate. At this time, the tool body 2 can rotate 90 degrees, thereby rotating the tool body 2 out from the reversing ring 15, which facilitates the subsequent processing operation.

[0056] When the synchronous slider 252 slides back from the flip groove 251 to the annular groove 25, the tool body 2 rotates and resets, so that the tool body 2 is re-stored in the reversing ring 15, and the cleaning plate 3 is located on the side wall of the tool body 2.

[0057] As the connecting frame 212 continues to rotate, the cleaning plate 3 and pressure plate 33 on the newly stored tool body 2 will slide to the pressing protrusion 341 on the synchronous ring 34. Through the pressing action of the pressing protrusion 341, the pressing protrusion 341 presses and rotates the pressure plate 33. The retaining shaft 332 on the pressure plate 33 rotates on the support frame 331. The torsion spring 333 between the support frame 331 and the retaining shaft 332 twists synchronously. The torsion spring 333 facilitates the subsequent reset operation.

[0058] A cleaning plate 3 is installed on the clasp 332. At this time, the cleaning plate 3 begins to rotate around the support frame 331. The position of the tool body 2 on the cleaning groove 31 changes, so that the brush 311 on the cleaning groove 31 slides on the tool body 2. The height of the cleaning groove 31 increases continuously, and the height of the brush 311 increases continuously, which can clean different positions of the tool body 2. Finally, all positions of the tool body 2 are cleaned. During the cleaning process, the brush 311 is equivalent to the tool body 2 sliding horizontally, which can clean the small spiral debris wrapped on the side wall of the tool body 2.

[0059] When the tool body 2 slides outward in the cleaning groove 31, the limiting spring 323 drives the slide plate 321 to slide outward continuously, which causes the slide plate 321 to slide on the limiting rod 322. The scraper 32 connected to the side wall of the slide plate 321 is attached to the side wall of the tool body 2. The scraper 32 is equivalent to the tool body 2 sliding vertically. Finally, the long spiral debris wrapped on the tool body 2 can be pushed upward, so that the debris and the tool body 2 are completely separated.

[0060] During the cleaning process described above, the tool body 2 is started to rotate, thereby cleaning the area around the tool body 2.

[0061] At this time, a vacuum system is connected to the air intake 131. The vacuum system can adsorb the debris that has been cleaned, and finally complete the debris cleaning operation. The vacuum system is existing technology and is not shown in the figure. Its working principle will not be described in detail here.
