New description: [New technical field] The improved large-aperture boring tool holder structure is mainly used to increase the structural strength and stability of large-aperture boring holders. [Prior Art] According to the 'creator' application on June 6, 1991, the application number: No. 091208403, and approved by the announcement, No. 5 φ 42026 "Precision boring device fine fine-tuning structure" The new patent case is mainly composed of a cutter bar, an adjustment seat, a pressure plate, a knife seat and a fine adjustment structure. The cutter bar is provided with a rail groove for adjusting the seat capacity, and is limited by the pressure plate to the adjustment seat. A hole holder is provided for the straight or horizontal boring holder, the straight boring holder is directly locked in the hole seat, and the horizontal boring holder is provided with a coarsely called adjustment hole, and then a bolt Locked in a screw hole seat embedded in the hole seat, the inside of the tool bar is provided with a radial hole along the direction of the track groove, and a vertical hole and a radial horizontal hole are penetrated through the axial direction above and below the radial hole, For the adjustment of the fine adjustment structure, the whole part, the driving part and the driving part are used, the top and the bottom part of the driving part are combined in the adjusting seat and the adjusting part, and the rotating part of the driving part is provided with the scaled turntable '(10) There is a flaw, the piece is provided with a worm of the material, and is set in the radial hole. Cheng and the screw piles, so as to adjust the pivot junction member disposed radially disposed bore; whereby the drive member can be turned through the driven member moving object of adjustment member and adjustment of the seat, to achieve fine-tuning. However, the above-mentioned "pre-existing patents for fine-tuning structures of precision boring tools" is still at least fine, but there are still at least problems and shortcomings that need to be overcome in the next job: 3 M360098 First, the arbor has a groove. The sliding seat of the adjusting seat can be used for sliding, and the pressing plate is screwed on the edge of the sliding seat; however, the adjusting plate must be assembled by screwing the pressing plate, whether it is assembly convenience or the whole In terms of structural strength, the ugly is relatively weak (four) weak, and at the same time, it is loose in terms of precision, and it is easy to affect the precision of processing because of the combined gap. 2. The outer part of the arbor corresponding to the adjusting seat is provided with a radial screw hole, and the b month b is fixed by the countersunk screw; however, the adjusting seat is only locked by the unilateral countersunk screw. The stability of the combination is not good, and it is easy to cause the adjustment seat to slightly shift due to the vibration during processing, thereby directly affecting the precision of the processing. 3. The inside of the arbor is provided with a non-penetrating radial hole along the direction of the track groove, and the axial vertical hole and the radial horizontal hole which are connected to the lower side of the radial hole but are not penetrated are used as the fine adjustment structure. At the same time, a screw hole is arranged outside the radial hole, and the driving member of the fine adjustment structure is provided with a groove ring corresponding to the screw hole, and is pivoted by the pivoting component; however, only the pivoting component of the single side is used for piercing When the drive member is pivoted, the stability of the combination is not good, which easily affects the smoothness of the drive, and the precision of the fine adjustment is affected by the combined gap. [New content] The creator is currently engaged in the manufacture and design of related products, and has accumulated many years of practical experience and experience. The problems and shortcomings of the large-aperture boring tool holder structure for the traditional use, actively investing in the spirit of innovation and improvement. , to complete the structural improvement of a large aperture pond hole. The new technical solution to solve the problem and the effect of the previous technology 4 M360098 is that the top of the knife has a red tail groove for the sliding seat of the adjustment seat, whether it is her loaded notes and the whole turning In terms of structural strength, the design of the tail groove is relatively easy and strong. At the same time, in terms of precision, it is also more rigorous. The combination earns a small amount, and the precision of the processing can be improved, and the efficiency is improved. The main purpose achiever. The new technical means of solving the problem 2 and the efficacy of the prior art are as follows: the outer hole and the bottom of the blade are respectively provided with corresponding through holes and screw holes, and the tailstock and the adjustment seat of the expanded slide are respectively The through hole and the long hole are provided for bolt through and locked, and the bolt is used for locking and locking, the stability of the combination is good, the displacement of the adjusting seat caused by the vibration can be reduced, and the precision of the processing can be improved. , with an improvement in efficacy, reaching for another purpose. The technical means of the new problem solving three and the efficacy of the prior art are three: the vortex rod of the fine adjustment structure is provided with a ring groove, and the outer ring surface of the second half ring fixing piece is provided. Cone hole, fine Φ Φ The knife seat is provided with a screw hole at the taper hole, which is used for locking the screw pile. The screw pile has a taper corresponding to the taper hole. When the stud is locked, it must be pushed by the taper part. The top cone hole is outwardly expanded by the two semi-annular fixing pieces, and the second half of the annular fixing piece can fully pivot the vortex rod, so that the stability of the combination is good, the rotation of the vortex rod is smoother, and the combined gap Small, so that the precision of fine-tuning is improved, and the efficiency is improved, and it is achieved for another purpose. [Embodiment] In order to make it easier for those who are familiar with this skill to understand the structure of the creation and the functional benefits that can be achieved, a detailed example of the 5 M360098 application is described. ·· A large-aperture boring tool holder structure improvement, please refer to the first and second figures.
