Abstract

A quick release chuck device has a body member defining an axially extending bore for receipt of a too shank. At least a portion of the bore is defined by a plurality of radially compressible and axially extending griping segments. The gripping segments are equally spaced and defined by axial slots extending form a front face of the body member. At least two axially extending and aligned recesses are defined on each of the gripping segments. An operating member is coaxial with and surrounds at least the gripping segments of the body member. The operating member defines a varying radial width channel with the recesses formed on the outside of the gripping segments. The operating member is axially movable relative to the body member. Actuating elements, such as balls, are disposed within the varying radial width channels. The actuating elements are movable within the channels by axial movement of the sleeve member form a gripping position wherein the balls are in a reduced radial width section of the channels causing the gripping segments to compress radially inward, and a release position wherein the balls move into a greater radial width section of the channels allowing radial expansion of the gripping segments.

V. Description of the invention (1) '' Printed by the Central Bureau of Standards of the Ministry of Economic Affairs and Consumer Cooperatives to print the invention of the agency _ This application is a partial continuation of the US application serial number 08 / 922,41 1 filed on September 3, 1997 . The invention relates to a tool holding device, which is configured to be attached to a transmission mandrel of a mechanical or power tool, and is used to fix a tool drill bit driven by the mechanical or power tool, and more particularly, it can quickly An exchangeable chuck device that allows the tool bit to be replaced without the use of external tools or wrenches. Any barrel or chuck used to secure a tool bit to a mechanical tool drive spindle, such as a slotting machine, must be locked and fixed in the longitudinal and radial directions with respect to the drive spindle. In other words, the chuck must be able to prevent the tool recognition head from rotating relative to the drive mandrel, and it must also prevent the chuck from moving into or out of the longitudinal axis from the drive mandrel. The importance of accuracy and safety considerations is important for high-speed machine tools such as slotters, stackers, and drywall milling cutters. For conventional systems, a pair of I-bits used to rotate a tool bit whose end is composed of a polygon or other polygonal contour is simply fitted to a relatively polygonal recess formed in the collet device. When using this conventional mechanism, the operator usually needs to use at least one wrench and mandrel lock, or two wrenches' to change the tool head. In another well-known device, the collet chuck utilizes a compressible collet which is longitudinally fixed and rotates to hold the tool bit. The jacket chuck is quite convenient and useful, and it does not need to rely on a multi-sided structure tool hoe to fix the tool. Therefore, any type of power drill or tool that has a round shank in nature --------- ^-(please read the precautions on the back first → write this page), tr wire paper size is applicable to China National Standard (CNS) Α4 specification (210X297 male f) ^ PATSiT ^ PuAPU-OSl-OOOSSpuOSi 5J-0003 · January 29, 1 Printed by the Central Standards Bureau of the Ministry of Economic Affairs and Consumer Cooperatives Λ 7 Η7 V. Description of the invention (2) , Can be fixed by a jacket collet device. However, the collet chuck does not have the function of quick exchange or quick release, but it is urgently needed in many applications. It is eager to have a portable tool, such as a jack or stacker adjuster 'which can utilize a quick release chuck device to relatively quickly and easily change the tool bit. However, when using a conventional quick release device, the tool shank portion must be polygonal in order to be tightly defined in the corresponding borehole in the quick change chuck device. This technology is ideal to have a quick-change chuck device that can be used with any type of tool drill with a cylindrical tool shank in order to increase the versatility and use of machine tools that employ such chuck devices. Simplicity of operation β And, for many types of conventional chucks, when tightening or operating the chuck, the tool chuck must be fixed at an ideal height relative to the chuck until the tool is tightly fixed by the chuck until. If the tool bit is not fixed during the locking operation, it will fall out or slide into the working interface of the chuck to the tool head in the direction of the power tool. This may be difficult to work with, ». First, especially when the area of the Jin chuck and tool head is limited, for example, when the space of the groove guide and chuck is relatively limited. This is especially inconvenient when the operator must use both hands to change the tool hoe. While one hand must hold the tool bit to ensure that it is maintained at an appropriate height, the other hand is used for chuck operation. The operator must also grip the tool bit with a relatively sharp cutting edge, which is clearly not ideal.

Description of the invention (彳 3) ——One-Provided with the longitudinal and axial arrangement of channels (34 Bu about circles 2 and 3, compressive The external radiation force is applied to the rear part of the longitudinal axis of the channel (34), that is, the position of the smallest radiation width where the ball (38) is located. Especially with regard to Figure 7, the applicant has also measured, preferably at A hole (78) is formed inside the drilled hole (18). The groove (78) is defined by a longitudinal recess on the inner circumferential surface of the segment (20) of the orange clip segment (20) defined by the outline of the hole (18). The successful claim is that the narrow gap (78) will cause the light-emitting layer to contract along the flat section (79) (Figure 7) of the borehole (18), and this direction is quite limited. Concentrated external forces in the front and rear areas of the defined longitudinal axis will increase the stiffness of the system and reduce the vibration of the tool handle inside the central segment of the orange segment. Still referring to Figure 7, drilling (18) is described as having Front diameter (86) is greater than rear straight Diameter (88) for a tapered bore. For a collet device with a capacity of 0,500 inches, the diameter of the front end of the silver hole (86) is about .503 inches, and it tapers to the back. (88) is about 0.500 inches. The preferred tapering range is from about 0.002 to about 0_004 throughout the longitudinal length of the borehole. However, it should be understood that 'is within the scope and spirit of the present invention. The tapering of any range in the field, and the degree of tapering, may vary depending on the chuck or the capacity. Without being limited to a particular theory, the applicant is convinced that tapering will result in a vertical hole. At the axial rear part, the phase compression or light shot multiplies the compression external force. For example, the radiation compression point applied by the 囷 7 'ball (38) is located on the flat surface (29) of the recess (28).

V. Description of the invention (1 4) The shaft rotates or bends. However, the hole (18) is at the position (31), which is a group of balls (3 8) at the rear of the longitudinal main axis. At the rear of the longitudinal axis of the point of application of the compression external force, it has its smallest diameter, as can be seen in detail in FIG. 7. At the position (3 1), the'drilling hole (18) has a diameter substantially equal to the tool shank, so that the contact starting point or near-contact point is defined at the point (3i). The applicant believes that tapered drilling will generate a certain degree or instantaneous arm between each applied external radiation force A and B, as well as pivot rotation or f-curvature point C, and the instantaneous arm will significantly strengthen the borehole (18 ) The compression external force at the minimum diameter (31) ^ In other words, two instantaneous arms will be generated; an instantaneous arm is generated from the radiation compression point of each longitudinal axial channel (34). And a chuck device with a 0.500 inch capacity without tapered boreholes, and described in FIG. 7 with a tapered iron hole, has a significant increase in the strength of the grip or slip torque. It should be understood that ′ With those skilled in this technology, the taper of the isometric hole (is) will depend on the size and capacity of the collet (10). Printed by the Central Laboratories of the Ministry of Economic Affairs, Shellfish Consumer Cooperative Figure 3 illustrates the chuck (10), in which the operating element or sleeve (44) has been moved forward to the loose position through the longitudinal axis. When the sleeve moves toward the direction, the frictional engagement between the sleeve (44) or the insert (48) and the ball (38) causes the ball (38) to roll forward toward the longitudinal axis to the channel (3 4 丨 In the area (42) with a large radiation width. At this position, the ball (38) does not apply an external force of compressive radiation to the segmented segment (20), and the segmented segment (20) will be free to expand outwardly, Therefore, when any tool shank is fixed in the bore (18), it will be released. In the embodiment described in Figs. 2 and 3, the sleeve member (44) includes an annular flange (45), which is defined in the rear area of the casing.

Description of the invention (5 Λ7 Η 7 The variation of the radiation width printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs is different. In other words, it is very likely that in the region of the reduced radiation width (40) of the channel (34) near the front surface (24), the radiation width is smaller than that at the rear channel of the longitudinal axis. Small radiation width (40) area. It should be understood that in the embodiment, as long as the running elements or balls (38) present in each channel have the same diameter, a large compressive external force should be generated on the vertical axis At the forward channel. Therefore, in each of the longitudinally and axially aligned channels, different degrees of compressive external force will be generated. In this embodiment, it is particularly preferred that the hole will be gradually tapered, as described in Figure 7 The middle one is combined with the central head to illustrate the embodiment, in which the annular flange (47) is formed at a front end of the sleeve (44).
