Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1 and fig. 2, an extended tool holder provided in an embodiment of the present invention includes a tool holder main body 1 and an extended section 2, which are integrally formed, wherein the extended section 2 is located on one side of the tool holder main body 1 and extends along a length direction; a cutter clamping inner hole 3 is formed in the lengthened section 2 along the length direction, and a plurality of cutter locking holes 4 vertically penetrate through the side wall; the cutter clamping inner hole 3 is used for placing a cutter bar of a cutter, the cutter and the lengthened section 2 are fixed after bolts are screwed in the cutter locking holes 4, and the clamped cutter is a round cutter; a plurality of mutually communicated cooling water flow passages 5 are formed in the tool apron main body 1; a first positioning surface 6 and a second positioning surface 7 which are perpendicular to each other are machined on one side of the tool apron main body 1; because adjacent cutters may interfere with the tool, the position of the lengthened section 2 can be adjusted to enlarge the rotation center, so that the cutters do not interfere, the distance between the central axis of the lengthened section 2 and the first positioning surface 6 can be set to be 80mm, 100mm or 120mm, and the actual use requirement is met; the tool apron body 1 is internally provided with tool apron lightening holes 8 in a penetrating mode, the tail ends of the tool apron lightening holes are connected in a sealing mode through the sealing cover, the tool apron lightening holes 8 are enlarged as much as possible on the premise that the rigidity of the tool apron is not influenced, the weight of the lengthened tool apron is reduced, and the influence of gravity on machining precision and quality is avoided.
