Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and in particular to a machine tool spindle with shock absorption function. Background Technology

[0002] Machine tools are a common type of processing equipment. When using a machine tool, the spindle drives the cutting tool to move and perform machining operations such as turning. However, the spindle of a typical machine tool cannot dampen the cutting tool during use, which can cause the cutting tool to be damaged due to excessive force, thus hindering the use of the equipment. Utility Model Content

[0003] The purpose of this invention is to provide a machine tool spindle with shock absorption function to solve the problems mentioned in the background art.

[0004] A machine tool spindle with shock absorption function includes a spindle body and a cutting tool: a buffer mechanism is provided inside the spindle body, a positioning mechanism is provided in the inner wall of the spindle body, the cutting tool is embedded in the spindle body, a limit ring is connected to one side of the opening of the spindle body, and the limit ring and the spindle body are fixed by bolts.

[0005] Preferably, the buffer mechanism includes a damping telescopic rod and a fixed ball, the damping telescopic rod is disposed inside the main shaft body, and the extended end of the damping telescopic rod is provided with a fixed ball.

[0006] When the device is in use, the damping telescopic rod pushes the fixed ball outward, thereby holding the cutter in place and limiting its movement. When the cutter is subjected to a large force, the cutter and the damping telescopic rod will extend or retract, thereby reducing the vibration of the cutter.

[0007] Preferably, the fixing ball is embedded inside the tool, and the tool has a corresponding arc-shaped groove inside.

[0008] Because the groove inside the tool is arc-shaped, the angle of the tool can be deflected to a certain extent, thereby providing further buffering for the tool.

[0009] Preferably, the positioning mechanism includes a fixing groove, a screw, a fixing spring, and a connecting rod. The fixing groove is evenly opened inside the damping telescopic rod, the fixing groove is threaded with a screw, the screw is installed inside the fixing spring, and the screw is installed inside the connecting rod.

[0010] When the device is in use, the position of the screw in the fixed groove is adjusted by rotating the screw, thereby adjusting the position of the connecting rod and adjusting the initial position of the connecting rod, thus positioning the cutter in different positions.

[0011] Preferably, the connecting rod passes through the screw, and a positioning ball is rotatably provided at one end of the connecting rod located outside the screw.

[0012] Because the connecting rod and the positioning ball can rotate relative to each other, the positioning ball can clamp and position the equipment, which facilitates the positioning of the tool. However, when the tool is subjected to a large force, it will deflect.

[0013] Preferably, a positioning ring is provided on the side of the limiting ring, the positioning ring is embedded in the inside of the fixing ring, and the fixing ring is opened inside the spindle body.

[0014] When the device is in use, the positioning ring is embedded inside the fixed ring to limit and fix the limiting ring, and then the limiting ring and the main shaft body are fixed together with bolts.

[0015] Preferably, the cutting tool is divided into an embedded end, an arc-shaped middle end, and an extended end. A buffer pad is provided on the side of the embedded end of the cutting tool, a locking block is provided on the arc-shaped middle end of the cutting tool, and a corresponding locking groove is provided in the limiting ring.

[0016] When the device is in use, the slot and the limiting ring are engaged, and there will be a certain gap between the limiting ring and the tool, so that the tool can deflect. At the same time, the buffer pad can also buffer and reduce the shock of the tool.

[0017] The beneficial effects of this utility model are:

[0018] 1. When the device is in use, the damping telescopic rod can limit the movement of the cutter. When the cutter is subjected to a large force, the cutter will drive the damping telescopic rod to move, thereby buffering and reducing the shock of the cutter, and thus increasing the stability of the equipment during use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In practical implementation: such as Figure 1-4 As shown, a machine tool spindle with shock absorption function includes a spindle body 1 and a cutting tool 13. The spindle body 1 is provided with a buffer mechanism inside and a positioning mechanism is provided in the inner wall of the spindle body 1. The cutting tool 13 is embedded in the spindle body 1. A limit ring 10 is connected to one side of the opening of the spindle body 1. The limit ring 10 and the spindle body 1 are fixed together by bolts.

[0027] The buffer mechanism includes a damping telescopic rod 2 and a fixed ball 3. The damping telescopic rod 2 is located inside the main shaft body 1, and the extended end of the damping telescopic rod 2 is provided with a fixed ball 3.

[0028] When the device is in use, the damping telescopic rod 2 will push the fixed ball 3 to move outward, thereby holding the cutter 13 against the fixed ball 3 and limiting the cutter 13. When the cutter 13 is subjected to a large force, the cutter 13 and the damping telescopic rod 2 will extend and retract, thereby reducing the vibration of the cutter 13.

[0029] The fixed ball 3 is embedded inside the tool 13, and the tool 13 has a corresponding arc-shaped groove inside.

[0030] Because the groove inside the tool 13 is arc-shaped, the angle of the tool 13 can be deflected to a certain extent, thereby providing further buffer for the tool.

[0031] The positioning mechanism includes a fixing groove 4, a screw 5, a fixing spring 6, and a connecting rod 7. The fixing groove 4 is evenly opened inside the damping telescopic rod 2. The screw 5 is threaded inside the fixing groove 4. The fixing spring 6 is installed inside the screw 5. The connecting rod 7 is installed inside the screw 5.

[0032] When the device is in use, the position of the screw 5 in the fixed groove 4 is adjusted by rotating the screw 5, thereby adjusting the position of the connecting rod 7 and adjusting the initial position of the connecting rod 7, so as to position the cutter 13 in different positions.

[0033] The connecting rod 7 passes through the screw 5, and a positioning ball 8 is rotatably installed at one end of the connecting rod 7 located outside the screw 5.

[0034] Since the connecting rod 7 and the positioning ball 8 can rotate relative to each other, the positioning ball 8 can clamp and position the equipment, which facilitates the positioning of the tool 13. However, when the tool 13 is subjected to a large force, it will deflect.

[0035] A positioning ring 11 is provided on the side of the limiting ring 10. The positioning ring 11 is embedded in the inside of the fixing ring 9, which is located inside the spindle body 1.

[0036] When the device is in use, the positioning ring 11 is embedded in the fixed ring 9 to limit and fix the limiting ring 10, and then the limiting ring 10 and the main shaft body 1 are fixed together by bolts.

[0037] The cutting tool 13 is divided into an embedded end, an arc-shaped middle end and an extended end. A buffer pad 12 is provided on the side of the embedded end of the cutting tool 13, and a locking block 14 is provided on the arc-shaped middle end of the cutting tool 13. A corresponding locking groove is provided in the limiting ring 10.

[0038] When the device is in use, the slot and the limiting ring 10 are engaged, and there will be a certain gap between the limiting ring 10 and the tool 13, so that the tool 13 can deflect. At the same time, the buffer pad 12 can also buffer and reduce the shock of the tool 13.
