Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology, and specifically a rotary CNC tool magazine that is easy to assemble and disassemble. Background Technology

[0002] CNC machine tools are automated machining equipment that perform various processes such as turning, machining, grinding, and engraving on workpieces through CNC programs. Because the shapes of the workpieces to be processed vary and the processing methods differ, CNC machine tools require a large number of different types and specifications of CNC cutting tools during the machining process. A tool magazine system is a system device that provides tool storage and changing capabilities during automated machining. It includes an automatic tool changer and a tool magazine that can store multiple tools, changing the traditional production method that relies primarily on manual tool changing, effectively improving machining efficiency and reducing production costs.

[0003] According to patent application number CN202410673787.1, a tool changing device for a CNC machine tool includes a vertical support, a turning mechanism slidably disposed on the outer surface of the vertical support, and a fully automatic tool magazine mechanism installed on one side of the vertical support. The fully automatic tool magazine mechanism includes an annular fixed base, a rotating tool post rotatably disposed inside the annular fixed base, and a top ring integrally formed on the top of the rotating tool post. A slot is opened on the top of the top ring, and the turning tool head is movably inserted into the slot. The problems with this patent are that when the tool magazine mechanism is installed on the CNC machine tool as a whole, the insertion-type installation of the turning tool head leads to inconvenience in installation, and it is easy to rotate and slip after installation. In addition, since the slot has a fixed size, the shape and specifications of the turning tool head that can be installed are limited. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a rotary CNC tool magazine that is easy to assemble and disassemble.

[0005] The purpose of this utility model can be achieved through the following technical solution: a rotary CNC tool magazine that is easy to disassemble and assemble, including a tool magazine disk, a tool holder and a rotary motor; the motor shaft of the rotary motor is connected to the telescopic rod of the lifting cylinder at the upper end through a coupling, and is connected to the tubular central bushing at the center of the tool magazine disk at the lower end through a bolt connection;

[0006] The tool magazine disc has a disc-shaped structure with an annular mounting groove on its outer edge. The mounting groove has several first bolt holes evenly spaced around its circumference. The tool holder is a one-piece molded structure, mainly consisting of a mounting part and clamping arms on both sides of the front end. The mounting part has several second bolt holes, which correspond to and mate with the first bolt holes. Fastening bolts are installed in both parts to fix the tool holder to the tool magazine disc. The inner side of the clamping arm is arc-shaped, with a fixing strip protruding in the middle of the arc-shaped inner wall and a baffle strip protruding at the bottom. The two clamping arms combine to form a semi-open circular clamping space in the center for quick clamping and engaging of CNC tools.

[0007] In the aforementioned rotary CNC tool magazine that is easy to assemble and disassemble, the lifting cylinder is vertically fixed to the moving mechanism of the CNC machine tool via an L-shaped fixing seat.

[0008] In the aforementioned rotary CNC tool magazine that is easy to assemble and disassemble, the tool magazine disc is provided with several discontinuous fan-shaped weight reduction holes evenly distributed around the central bushing. The tool magazine disc connecting frame between the weight reduction holes is integrally formed with triangular structural ribs that radiate outward from the side wall of the central bushing.

[0009] In the aforementioned rotary CNC tool magazine that is easy to assemble and disassemble, a deformation groove is provided between the roots of the two clamping arms on both sides of the tool holder at the front end of the mounting part, and a buffer groove is provided at the extension connection between the outer side of the clamping arm and the mounting part.

[0010] Compared with existing technologies, the rotary CNC tool magazine provided by this utility model is easy to assemble and disassemble. On the one hand, it achieves convenient connection between the tool magazine disc and the tool holder through bolt connection. On the other hand, the semi-open clamping arm of the tool holder enables quick clamping and engagement between the CNC tool and the tool holder, making the CNC tool magazine easy to assemble, disassemble, and adjust for tool changes. The locking strip inside the clamping arm prevents the CNC tool from rotating and slipping after installation, resulting in better stability of the CNC tool during operation. The clamping arms on both sides have a certain degree of elasticity, which can accommodate CNC tools of different shapes and sizes within a certain range in the clamping space, making it more flexible and practical.

Detailed Implementation

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1 to 2 As shown, this easily detachable rotary CNC tool magazine includes a tool magazine disk 100, tool holders 200, and a rotary motor 310. The motor shaft 311 of the rotary motor 310 is connected at its upper end to the telescopic rod of a lifting cylinder 320 via a coupling 330. The lifting cylinder 320 is vertically fixed to the moving mechanism of the CNC machine tool via an L-shaped mounting base 321. The motor shaft 311 of the rotary motor 310 is connected at its lower end to the tool magazine disk 100. The tool magazine disk 100 has a disc-shaped structure, and several tool holders 200 are evenly mounted circumferentially on its outer edge.

[0016] like Figure 2 As shown, a tubular central bushing 110 is formed at the center of the tool magazine 100. The lower end of the motor shaft 311 of the rotary motor 310 passes through the central bushing 110 and abuts against a fixing washer at the bottom of the tool magazine 100 at its tail end. The outer diameter of the fixing washer is larger than the inner diameter of the central bushing 110. A fixing bolt passes through the fixing washer from bottom to top and is fixedly connected to the lower end of the motor shaft 311. Thus, the tool magazine 100 is fixedly connected to the lower end of the motor shaft 311 by bolt connection, so that the rotary motor 310 can drive the tool magazine 100 to rotate and change tools.

[0017] The tool magazine disc 100 has several discontinuous fan-shaped weight-reducing holes 120 evenly distributed around the central bushing 110. These holes reduce the overall weight of the tool magazine disc 100 while maintaining its overall strength, thus saving material costs. Triangular structural ribs 111 are integrally formed on the tool magazine disc 100 connecting frame between the weight-reducing holes 120, extending radially outward from the sidewall of the central bushing 110. These ribs strengthen the structural strength of the tool magazine disc 100 and diagonally distribute pressure. An annular mounting groove 130 is formed at the outer edge of the disc of the tool magazine disc 100, and several first bolt holes 131 are evenly distributed around the circumference of the mounting groove 130.

[0018] The tool holder 200 is a one-piece molded structure, mainly including a mounting part 210 and clamping arms 220 on both sides of the front end. The mounting part 210 has several second bolt holes 211, which correspond to and mate with the first bolt holes 131. Fastening bolts 212 are installed in both of them, and the tool holder 200 is fixed to the tool magazine 100 by the fastening bolts 212, realizing a convenient connection between the tool magazine 100 and the tool holder 200.

[0019] The inner side of the clamping arm 220 is arc-shaped, and a fixing strip 221 is formed by a protrusion in the middle of its arc-shaped inner wall. The fixing strip 221 is used to clamp and connect with the CNC tool, making it less likely for the CNC tool to rotate or slip after installation, and improving the stability of the CNC tool during operation. A baffle strip 222 is formed by a protrusion at the bottom of the arc-shaped inner wall of the clamping arm 220. The baffle strip 222 is used to prevent the CNC tool from sliding down. The two clamping arms 220 are combined to form a semi-open circular clamping space 223 in the center, realizing quick clamping and engagement between the CNC tool and the tool holder 200, making the CNC tool magazine easy to disassemble, assemble, and adjust for tool changes.

[0020] To further explain, a deformation groove 230 is provided between the roots of the two clamping arms 220 on both sides of the tool holder 200 at the front end of the mounting part 210, and a buffer groove 240 is recessed inward at the extension connection between the outer side of the clamping arm 220 and the mounting part 210. The two clamping arms 220 have a certain degree of elasticity, which allows CNC tools of different shapes and sizes to be installed within a certain range in the clamping space 223. When the outer diameter of the clamped CNC tool is large, the two clamping arms 220 are expanded, and the deformation groove 230 and the buffer groove 240 deform accordingly, thereby dispersing stress and playing a role in buffering and strengthening the structural strength, making the CNC tool magazine more flexible and practical.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0022] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
