Description

Technical Field

[0001] This utility model relates to the field of lathe tool technology, and in particular to a lathe tool holder with anti-vibration function. Background Technology

[0002] A lathe tool is a cutting tool with a single cutting section used for turning operations. Lathe tools are among the most widely used cutting tools in machining. The working part of a lathe tool is what generates and handles chips, including the cutting edge, structures that break or coil the chips, spaces for chip removal or storage, and channels for cutting fluid. A lathe tool needs to be connected to the body using a tool holder to be put into operation.

[0003] When existing lathe tools are used for turning, the workpiece rotates and moves relative to the tool, causing the tool to vibrate during machining. Excessive vibration can lead to periodic chatter marks on the workpiece surface, significantly reducing machining accuracy and surface finish. It can also accelerate tool wear and even cause chipping or breakage. However, existing tool holders often have unsatisfactory anti-vibration effects, and when the anti-vibration effect of the anti-vibration components is not up to expectations, workers cannot make a clear judgment. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the anti-vibration effect of existing lathe tool holders is not ideal, and that it is impossible to make a direct judgment when the anti-vibration effect does not meet expectations. Therefore, this invention proposes a lathe tool holder with anti-vibration function.

[0007] Preferably, the inner wall of the load-bearing groove is fixedly connected to two first rotating rods, the outer surfaces of the two first rotating rods are rotatably connected to rotating connecting plates, the inner walls of the two rotating connecting plates are rotatably connected to second rotating rods, and the outer surfaces of the two second rotating rods are respectively fixedly connected to two sliding grooves.

[0008] Preferably, the force-sharing mechanism further includes two limiting grooves, both of which are formed on the inner sidewall of the cutting tool grooving shank, and the outer surfaces of the two sliding grooves are slidably connected to the two limiting grooves respectively.

[0009] Preferably, the integrated prompting and buffering mechanism further includes a trigger button, a connecting disc is fixedly connected to the left side of the trigger button, and two connecting plates are fixedly connected to the outer surface of the connecting disc, with the outer surfaces of the two connecting plates being fixedly connected to the load-bearing groove.

[0012] Compared with the prior art, this utility model provides a lathe tool holder with anti-vibration function, which has the following beneficial effects:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A lathe tool holder with vibration damping function includes a connecting rod 1, a tool holder 2 mounted on the outer surface of the connecting rod 1, and a tool body 3 mounted on the outer surface of the tool holder 2. The connecting rod 1 and the tool holder 2 are connected to each other and to the tool body 3 by conventional lathe tool connecting parts such as bolts. A grooving shank 4 is slidably connected to the outer surface of the connecting rod 1. A damper 5 is fixedly connected to the right side of the connecting rod 1. The outer surface of the damper 5 is slidably connected to the grooving shank 4. There is a large friction between the outer surface of the damper 5 and the grooving shank 4, which can dampen the movement of the connecting rod 1.

[0021] A force-sharing mechanism 6 is provided on the right side of the damper 5. The force-sharing mechanism 6 includes a bearing groove 601 and two sliding grooves 605. The bearing groove 601 is fixedly connected to the damper 5. Two first rotating rods 602 are fixedly connected to the inner wall of the bearing groove 601. Rotating connecting plates 603 are rotatably connected to the outer surfaces of the two first rotating rods 602. Second rotating rods 604 are rotatably connected to the inner walls of the two rotating connecting plates 603. The outer surfaces of the two second rotating rods 604 are fixedly connected to the two sliding grooves 605 respectively. By using the cooperation between the first rotating rods 602, the rotating connecting plates 603, the second rotating rods 604 and the sliding grooves 605, the horizontal rightward thrust can be dispersed, and the thrust generated when the cutting tool body 3 vibrates during operation can be dispersed.

[0022] The force-sharing mechanism 6 also includes two limiting grooves 606, both of which are formed on the inner side wall of the cutting tool grooving shank 4. The outer surfaces of the two sliding grooves 605 are slidably connected to the two limiting grooves 606 respectively. The limiting grooves 606 can guide the sliding of the sliding grooves 605.

[0023] A push-button switch 8 is installed on the inner wall of the grooving shank 4. A light 10 is installed on the upper surface of the connecting rod 1. A controller 9 is installed on the upper surface of the connecting rod 1. The controller 9 is connected to the light 10 via a wire. When the push-button switch 8 is pressed, a signal is transmitted to the controller 9, which can turn on the light 10 to alert the worker.

[0024] The left side of the push-button switch 8 is provided with a prompting buffer mechanism 7, which includes a buffer spring 704 and a trigger button 703. A connecting disc 702 is fixedly connected to the left side of the trigger button 703. Two connecting plates 701 are fixedly connected to the outer surface of the connecting disc 702. The outer surfaces of the two connecting plates 701 are fixedly connected to the bearing groove 601. By using the cooperation of the connecting plates 701 and the connecting disc 702, lateral interference with the displacement of the rotating connecting plate 603 can be avoided.

[0025] The two ends of the buffer spring 704 are fixedly connected to the right side of the connecting disc 702 and the inner side wall of the cutting tool grooving shank 4, respectively. The buffer spring 704 is a common and commercially available buffer spring 704 with buffering function.

[0026] Working principle: When the cutting tool body 3 is used to machine the workpiece, the cutting tool body 3 will vibrate because the workpiece is rotating and moving relative to the cutting tool body 3. The vibration of the cutting tool body 3 will drive the cutting tool holder 2 and the connecting rod 1 to move. When the connecting rod 1 moves, it will drive the damper 5 and the bearing groove 601 to move. The bearing groove 601 will push the two rotating connecting plates 603 and the sliding groove 605 to move. In addition, the bearing groove 601 will drive the connecting plate 701 and the connecting disc 702 to compress the buffer spring 704. Under the combined action of the damping force of the damper 5, the component force of the component force mechanism 6 and the buffering of the buffer spring 704, the vibration of the cutting tool body 3 can be buffered, thus avoiding the phenomenon of accelerated wear of the cutting tool body 3, poor machining quality of the workpiece and chipping or breakage of the cutting tool body 3 caused by high frequency vibration. When the connecting disc 702 moves, causing the trigger button 703 to move and press the push-button switch 8, the push-button switch 8 will transmit a signal to the controller 9, which will then control the lighting lamp 10 to turn on. This indicates that the connecting rod 1 has still moved to its limit distance after being buffered by the damper 5, the force component mechanism 6, and the buffer spring 704. Therefore, if the lighting lamp 10 is on at a high frequency for a long time, it means that the buffering effect of the damper 5, the force component mechanism 6, and the buffer spring 704 is no longer sufficient to counteract the vibration of the cutting tool body 3, and the damper 5, the force component mechanism 6, and the buffer spring 704 need to be repaired or replaced.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
