Description of the invention (Ο [Background of the invention] 1 Field of the invention The present invention is generally like an improved type used in impact cutting machines such as electric drills or electric hammers Cutting tool clamping device. 2. Background of the Related Art Impact cutting machine machines are well known in the industry, which are designed to provide rotation and impact or vibration along the axial direction of a cutting tool. Impact cutting machine machines usually have a clamp to rigidly clamp Holding a cutting tool. Here is an example of a clamp including a locking member. Each of the locking members has a protrusion that tightly fits outside a small diameter portion formed on a shank of the cutting tool The cutting tool is centered on the surface, and when an impact is applied to the cutting tool during operation of the impact cutting machine, it is made to conform to a side wall of the small-diameter portion of the cutting tool to limit the movement of the cutting tool before. The defect encountered by the above-mentioned traditional clamp is that the cutting tool advances to press against and move the side wall of the small diameter part of the locking member, thereby generating local stress Acting on other components of the fixture, causing them to deform or break. [Summary of the Invention] Therefore, the main purpose of the present invention is to avoid the lack of the prior art. Another object of the present invention is to provide a tool holder for impact cutting machine According to one aspect of the present invention, there is to be provided a device for holding a cutting tool in an impact cutting machine machine, wherein the machine provides the cutting tool The paper scale is in accordance with Chinese National Standard (CNS) Α4 specification (210Χ297mm) (please read the precautions on the back before filling in this page).

Description of the invention (+) Vibration, the impact is a shocker 1 1 transmitted to the cutting tool 1 via the second hammer 9. In short, the rotation of the motor 100 provides rotation to the cutting tool 1 and impact in the longitudinal direction of the cutting tool 1. The cutting tool holder 2 is formed with three holes or holes 2 a on its cylindrical end 2 b. As shown in the second figure, the three are distributed at a certain distance along a circumferential direction. In these holes 2a, three locking members 5, respectively, are installed as a part of a clamp to prevent the cutting tool 1 from falling off and slanting during the operation of the impact cutting tool. Each locking member 5 is designed to fit a small-diameter surface 1 a formed on the shank of the cutting tool 1 and a tapered end surface. The cutting tool holder 2 further includes a second holder 7 for limiting the movement of the locking member 5 in the radial direction. A grip sleeve 6 is connected to the circumferential table of the gripper 7. -The front cover 8, a flat plate 14 made of plastic material, a cushion 15 and a snap ring 16 are placed on the upper end of the cutter holder 2 to prevent the second holder 7 and the grip sleeve 6 Fall off in the direction of impact. As shown in the second figure, the second holder 7 has a recess or groove 7a formed on it, and a contact surface 7b formed on its inner wall. These grooves are used to move the locking member 5 in the radial direction when installing or removing the cutting tool. The contact surfaces 7 b are used to hold the outer surface of the locking member 5 so that the locking member 5 fits the cutting tool 10. As shown in the third to fifth figures, each locking member is composed of a flat member 30 and a protrusion 40 composition. The flat member 30 has a rounded tip end and a flat contact surface 5c. The protrusion 40 is formed at one end of the contact surface 5c. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) -------- jf installed ---------.

The description of invention (s) on the side, so that it can be defined on both sides The holding edge portion 50 of the flat plate member 30 has a tapered portion defined by an upper contact surface 5 a and an inverted contact surface 5 b. As can be seen from the first and second figures, the holding edge 50 of the flat member 30 is at the end 2 b formed between the plane 2c formed around the hole 2 a of the cutter holder 2 and the second holder 7 Between the contact surfaces 7b, and against the second holder 7, to prevent the locking member 5 from moving in the radial direction of the cutter holder during the operation of the impact cutter machine. The protrusion 40 of each fastener 5 protrudes into the cutter holder 7 and passes through an opening 2 a, and the above contact surface 5 a contacts the small-diameter surface 1 a of the cutter 1 to come from the operation of the impact cutter machine The cutting tool 1 is firmly clamped in the process. The contact surface 5 a above the protrusion 40 is clearly shown in the fifth figure, and is bent to increase the area of contact with the small-diameter surface of the cutting tool 1. By rotating the grip sleeve 6, the relative position of the locking member 5 and the second holder 7 can be changed to allow the locking member 5 to move in the radial direction. The second holder 7 has a steel ball and a C-shaped flat spring 13 to control and maintain its rotation. In operation, when the cutting tool 1 is installed in the cutting tool holder, the grip 6, S can be rotated to move the contact surface 5A of the locking member 5 into a small diameter surface that fits the cutting tool 1 to center the cutting tool 1. When the impact acts on the cutting tool to advance it towards a workpiece, the contact surface of each fastener is made to fit the tapered end surface 1 b of the cutting tool 1. The impact on the contact surface 5 a above each lock is firstly the falling wall of one of the flat plates 14, the inner wall of the second holder 7, the contact surface 5c, and the hollow end 2b of the cutter holder 2 The size of the paper is applicable to the Chinese National Standard (CNS) A4 format (210X297mm) Binding-binding ^ ball (please read the precautions on the back and then fill out this page) A7 B7 5. Description of the invention (each) Accept, then pass The locking member 5 is transmitted to the cutter holder 2 and the sleeve 3, and then absorbed by the latter two. As shown in the first figure, once the impact is transmitted, the locking member 5 is held between the inner wall of the second holder 7 and the flat end of the cutter holder 2 by the flat member 30 to prevent its radial movement . Although the present invention has been shown in accordance with preferred embodiments for better understanding, it should be understood that the present invention can be implemented in various forms without departing from the principles of the present invention. Therefore, the present invention should be understood to include all feasible embodiments and modifications to the illustrated embodiments.
