New description: [New technical field] This creation relates to a jaw structure for hydraulic chucks, especially a jaw structure for hydraulic chucks suitable for metalworking machines such as lathes. [Prior Art] According to the current more common lathe hydraulic collet, it mainly has a heart-turning lathe spindle transfer stage _ body 'and a three-decreasing arrangement of the fixture placed in the head body' The towel is attached to the inside of the Lang body = the mechanism is connected (the general transmission mechanism has a woman, a rocker arm, a wedge rod, etc., and the more commonly used one is a wedge rod), and the wedge shape In the case of the tie rod, the horizontal tie rod can be driven by the hydraulic cylinder to make an axial reciprocating motion, and can be driven by the wedges of the clamps. The shifting is performed by changing the size of the opening between the clamps to hold the workpieces of different outer diameters. / '―General hydraulic chuck 9 is the structure shown in Figs. 1 and 2, and each set of clamps 9 1 is provided with a claw seat 93 in the radial chute 94 of the chuck body 92, and is matched with f" The bolts of the bolt locking claw seat 9 3 are 9 pieces of particles. Therefore, the jaws 9 and the 2 seats 9 3 can adjust the relative positions of each other so as to be more suitable for the workpiece 9 8 - the jaw 95 and the claw seat 93 of the U1 Adjusting the position of each other will cause the two jaws 95 to be clamped and clamped to the workpiece 98 for processing. 'Current jaws 9 5 and claws qq ο 丨 丨 、, * # This uses continuous small dent rows 9 7 , 9 9 water identification meter is adjusted by this position 疋 j too tooth row 9 7 , 9 9 shape tiny , 3 M367047 and continuous dense arrangement, so it is difficult for the staff to quickly and accurately identify the calculation, so that the adjustment of the positioning operation is laborious and time consuming and easily cause relative position error, which seriously affects the processing quality of the workpiece. Therefore, how to solve the above problems and deficiencies is the direction that the relevant industry is eager to study and develop. [New content] The main purpose and function of this creation is that the clamping jaws of the clamps of the hydraulic chucks and the corresponding movable claw seats cooperate with each other to indicate the marking side of the indicator mark. (4) Perform quick and precise positioning adjustment. The oil ends are configured with each other (4) and the same center-pitch position to ensure that the concentric displacement clamps the workpiece for processing and improves the metal processing efficiency. In order to achieve the goal, most of the jaws of this creation are bolted to the inside of the movable claw seat via a through hole, and the movable claw seat contact material is provided with a majority of the lateral hustle and bustle _; Most of the jaws are each a rectangular body having a _ end portion, a relatively outward end portion and opposite side walls, and each of the jaws has a side surface or a side wall portion which is positioned in a row and has a majority of each other. The indicator marks arranged at equal intervals are to locate the teeth by the number of shirts. Preferably, the positioning tooth of the clamping jaw has a concave end, and the movable claw has a convex end to correspond to the concave end of the jaw; the surface of the jaw wall is not The standard is a straight line 'toward the concave end of the relative positioning tooth. The side advances the stepping jaws. The majority of the indicator marks are connected to the concave ends of the opposite positioning teeth. Each of the claws is connected to the side of the positioning teeth. [Embodiment] M367047. As the purpose of the invention, the technical means and its efficacy are given as follows. The following is a description of the possible examples. First, please refer to Figures 3 and 4 for the creation of oil. The design of the clamping clamp and the jaw structure is also applicable to metal processing machines such as lathes. In the past, the external control of the metal workpiece was used for reinforcement. As shown in the figure, the plurality of jaws 3 are disposed on the opposite movable claw seat 2 of the front side of the chuck body 放射 radial radial displacement, and the head body is provided with a plurality of inspections. The secret seat 2 is displaced by the brewing direction, and Φ the plurality of jaws 3 are respectively fixed to the movable claw base 2. In the preferred embodiment shown in the third to seventh, the present jaws 3 are each provided as a rectangular body having an inward end 3 i, a relatively outward end 3 2 and opposite sides of the wall. The portion 34 is passed through the through hole 34 to lock the relative screw hole 23 of the inner clamp block 21 of the movable claw base 2 to be positioned to form a clamp and the movable claw base 2 is front. A plurality of laterally adjacent positioning teeth 25, 35 are provided adjacent to the back of the jaw 3 to be in contact with each other. The present invention is mainly provided with the indication marks 3 7 ' of the respective claws 3, which are arranged on the side of the side or the side wall portions 3 3 toward the row of positioning teeth 35, and which are arranged at equal intervals with each other to indicate the positioning teeth 35. Each set of clamps that are used as the oil pressure surface can be adjusted according to the diameter of the workpiece, and the jaws 3 of the respective sets of clamps and the corresponding movable claw bases 2 are matched with each other to indicate that the mark 3 7 does not function 'can be as 4, 5, 9 And 1(10) for fast and precise positioning adjustment, so that each of the jaws 3 is aligned with the same indicator mark 3 7 at the inner end of the movable lost seat 2 to accurately control the inward of each jaw 3 The end portions 3丄 are configured to be identical to each other, and the same center-to-center spacing position is confirmed. The read-and-shift workpiece is matched with 5 M367047 for processing, and the inner end portion 3丄 and the outward end portion 3 of the jaw 3 are not as shown in FIG. The positioning direction can be used in the direction of the adjustment, and the positioning steps 38, 39 can be made with the I member facing the outer end portion 3 2 . - Continuing to explain the design of the jaw structure for the hydraulic collet of the present invention, as shown in Figures 3 to 7, and the two side wall portions 3 of the jaws 3 of the missing piece may each have a plurality of rows corresponding to each other. '. It has been 3 7 ’ to facilitate the understanding of jh. In the tenth embodiment, the clamping teeth 3 of each jaw 3 have a toothed end 36, and the positioning teeth 25 of the movable jaw 2 have a toothed end 26, which is compatible with the teeth of the jaw 3. The recessed end 36, and a plurality of indicator marks 3 on the surface of the wall portion 3 3 of each of the claws 3 can be set as straight lines to face the concave end 36 of the opposing clamp teeth 35 for easy identification. Further, it is preferable to connect a plurality of indicator marks 3 7 of the respective claws 3 to the side of the concave end 36 of the opposite positioning teeth 3 for convenient identification. The clamping jaws 3 of the first set of clamps of the creation oil (4) and the corresponding movable claw bases 2 cooperate with each other to indicate that the marking action of the clamps 3 can be quickly adjusted to accurately control the inward end of each of the jaws 3 3! Concentric circles and the same center-pitch position are formed with each other, and the heterocentric displacement clamps the workpiece for processing, and a new patent application is filed according to law. The implementation of the above-mentioned cans is convenient for the creation of this book, and is not intended to be limited. In the spirit of this creation, all kinds of simple changes and modifications that can be made by those skilled in the industry should still be included in the scope of the following patent application. .
