Description

Technical Field

[0001] This utility model relates to the field of CNC equipment technology, specifically to a cutting tool mounting shaft. Background Technology

[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. In a broad sense, cutting tools include not only cutting tools but also grinding wheels. During the installation of cutting tools, it is often necessary to install and fix them to CNC equipment through the cooperation of mounting shafts.

[0003] However, the existing mounting shafts still have the following technical problems in use:

[0004] During the machining process of metal parts by cutting tools, a small amount of waste chips inevitably adhere to the outside of the tool. However, the current mounting shaft does not have ultrasonic vibration effect to quickly vibrate and remove the waste chips from the outside of the tool, thus ensuring the machining quality. Furthermore, the current mounting shaft is not convenient for quickly and securely fixing tools of different sizes.

[0005] Therefore, a cutting tool mounting shaft is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a cutting tool mounting shaft to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting tool mounting shaft, comprising a shaft rod, an internal mounting cavity, a cutting tool longitudinally arranged inside the mounting cavity, a first threaded tube fixedly sleeved on the outer wall of the shaft rod, a second threaded tube being threaded on the outer thread of the first threaded tube, cavities opening on the left and right sides of the shaft rod, extrusion blocks slidably arranged inside the two cavities, brackets fixedly mounted on the left and right ends of the inner wall of the shaft rod, movable rods slidably mounted on the side walls of the two brackets, the opposite ends of the two movable rods being fixedly connected to the side walls of the extrusion blocks, vertical plates fixedly mounted on the adjacent ends of the two movable rods, uniformly arranged clamping plates fixedly mounted on the side walls of the vertical plates, and springs sleeved on the outer side of the movable rods, one end of the spring being fixedly connected to the side wall of the extrusion block, and the other end of the spring being fixedly connected to the inner wall of the brackets;

[0008] Mounting boxes are fixed to both sides of the lower end of the inner wall of the shaft, and ultrasonic devices are fixed inside the two mounting boxes.

[0009] Preferably, the outer wall of the first threaded tube is provided with a first thread, and the inner wall of the second threaded tube is provided with a second thread, and the first thread and the second thread are compatible with each other.

[0010] Preferably, the opposite side of the two extrusion blocks is an inclined surface, and the lower side of the second threaded tube is in contact with the inclined surface of the two extrusion blocks.

[0011] Preferably, mounting bolts are threaded on both the left and right sides of the shaft, and both mounting boxes are fixedly connected to the shaft by mounting bolts.

[0012] Preferably, the upper end of the outer wall of the tool is provided with evenly arranged slots, and the clamping plate is engaged with the slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This application rotates the second threaded tube outside the first threaded tube, so that the second threaded tube moves downward to squeeze the two extrusion blocks. The two extrusion blocks drive the moving rod, vertical plate and clamping plate on the side wall to engage the tool slot, so that tools of different diameters can be installed and fixed. Since the clamping plate and the slot can be matched, and multiple slots and multiple clamping plates are evenly arranged to cooperate, the installation stability is increased.

[0015] 2) A symmetrical ultrasonic device is installed inside the shaft. The ultrasonic device can generate vibration to remove the small amount of waste chips attached to the outside of the tool, thus ensuring the machining quality of the tool. Attached Figure Description

[0024] Example:

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A cutting tool mounting shaft includes a shaft 1, an internal mounting cavity, a cutting tool 2 longitudinally mounted inside the mounting cavity, a first threaded tube 3 fixedly sleeved on the outer wall of the shaft 1, a second threaded tube 4 threaded on the outer thread of the first threaded tube 3, cavities on the left and right sides of the shaft 1, a pressing block 5 slidably mounted inside each of the two cavities, brackets 6 fixedly mounted on the left and right ends of the inner wall of the shaft 1, movable rods 7 slidably mounted on the side walls of the two brackets 6, the opposite ends of the two movable rods 7 fixedly connected to the side walls of the pressing block 5, vertical plates 8 fixedly mounted on the near ends of the two movable rods 7, uniformly arranged clamping plates 9 fixedly mounted on the side walls of the vertical plates 8, and a spring 10 sleeved on the outside of the movable rods 7, one end of the spring 10 fixedly connected to the side wall of the pressing block 5, and the other end of the spring 10 fixedly connected to the inner wall of the bracket 6.

[0027] Mounting boxes 11 are fixed on both sides of the lower end of the inner wall of the shaft 1. An ultrasonic device 12 is fixed inside the two mounting boxes 11. The ultrasonic device 12 can generate vibration, thereby shaking off the waste chips attached to the outer wall of the tool 2.

[0028] The outer wall of the first threaded tube 3 is provided with a first thread, and the inner wall of the second threaded tube 4 is provided with a second thread. The first thread and the second thread are compatible with each other. By rotating the second threaded tube 4, the second threaded tube 4 can be adjusted up and down.

[0029] The two extrusion blocks 5 have an inclined surface on the opposite side. The lower side of the second threaded tube 4 is in contact with the inclined surface of the two extrusion blocks 5. The extrusion blocks 5 are extruded by the downward movement of the second threaded tube 4.

[0030] The left and right sides of the shaft 1 are threaded with mounting bolts, and both mounting boxes 11 are fixedly connected to the shaft 1 by mounting bolts.

[0031] The upper end of the outer wall of the tool 2 is provided with evenly arranged slots, and the clamping plate 9 engages with the slots to effectively limit the movement of the tool 2.

[0032] Working principle:

[0033] The cutter 2 is placed longitudinally inside the shaft 1. By rotating the second threaded tube 4, the second threaded tube 4 moves downward outside the first threaded tube 3. The second threaded tube 4 squeezes the two extrusion blocks 5, thereby causing the two extrusion blocks 5 to move the moving rod 7 on the side wall. The moving rod 7 drives the vertical plate 8 and clamping plate 9 on the side wall to move. The clamping plate 9 engages with the slot on the outer wall of the cutter 2, thereby installing and fixing it. The shaft 1 is connected to the mechanical equipment. During the operation of the cutter 2, the two ultrasonic devices 12 are activated. The vibration generated by the ultrasonic devices 12 can vibrate away the waste chips attached to the outer wall of the cutter 2.
