Detailed Description

In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In order to facilitate the technical solution disclosed by the present invention to be fully understood by those skilled in the art, the following detailed description is made in combination with the specific embodiments, and fig. 3 shows a schematic structural diagram of the present invention when the tool post is installed on the tool adjusting seat of the machine tool, the tool is assembled thereon, and the tool post is integrally assembled on the tool adjusting seat of the machine tool, so as to implement cutting processing of the workpiece. Fig. 4 and 5 respectively show a schematic structural diagram and a cross-sectional view of a first embodiment of the middle tool apron of the present invention, which mainly comprises a tool apron body 1 and a locking screw 2. Wherein, a first cutter mounting groove 11 and a second cutter mounting groove 12 which are arranged in parallel are respectively arranged on the left side wall and the right side wall of the cutter holder body 1. And a series of first threaded holes 13 which are uniformly distributed along the front-back direction and are matched with the locking screws 2 are respectively arranged on the top walls of the first cutter mounting groove 11 and the second cutter mounting groove 12. When a tool is placed in position relative to the first tool mounting pocket 11 and the second tool mounting pocket 12, the locking screw 2 is tightened. Therefore, the processing machine tool can execute two procedures at the same time, and the processing efficiency of the workpiece is improved. And when the execution contents of the processes are different, the frequency of changing the tools and adjusting the relative position of the tool adjusting seat of the machine tool can be reduced, so that the labor intensity of operators is reduced. In addition, the process of disassembling and assembling the cutter is convenient and fast.

In addition, the firm stability of the tool fixing is affected by the protruding length h of the locking screw 2 (as shown in fig. 5), so that the h value needs to be strictly controlled in the practical application process, and is generally not more than 3 cm.

In addition, in order to improve the reliability of the fixing of the tool apron and the machine tool adjusting seat and prevent the phenomenon of fixing failure caused by the overlarge shearing force applied to the bolt for fixing the tool apron, a limiting step 15 (as shown in fig. 6) can also extend downwards along the bottom wall of the tool apron body 1, and correspondingly, a limiting groove matched with the limiting step 15 is formed in the upper plane of the machine tool adjusting seat.

Fig. 7 and 8 respectively show a schematic structural diagram and a cross-sectional view of a second embodiment of the middle knife holder of the present invention, and the difference between the first embodiment and the second embodiment is that a first protection adjusting shim plate 3 and a second protection adjusting shim plate 4 are additionally provided, which are respectively and correspondingly placed in the first and second

knife mounting grooves

11 and 12, and pressed directly above the knife, and are always pressed by the locking screw 2. Therefore, on one hand, the value of the extending length h of the locking screw 2 can be conveniently and effectively adjusted by increasing or decreasing the thicknesses of the first protective adjusting base plate 3 and the second protective adjusting base plate 4, and the reliability of cutter fixing is ensured; on the other hand, the existence of the first protection adjusting base plate 3 and the second protection adjusting base plate 4 can also effectively increase the bearing area of the cutter, and prevent the surface of the cutter from being damaged by pressure.

Fig. 9 and 10 respectively show a schematic structural diagram and a cross-sectional view of a third embodiment of the middle tool holder of the present invention, which are different from the second embodiment in that an adjusting screw 5 is additionally disposed on the tool holder and disposed on the inner side of the tool, and correspondingly, a second threaded hole 14 (as shown in fig. 11) adapted to the adjusting screw 5 is disposed on the inner side walls of the first tool mounting groove 11 and the second tool mounting groove 12. The number of adjustment screws 5 on the side wall of the first tool-mount channel 11 or the second tool-mount channel 12 is not less than 2 for each case, and they are linearly arrayed in the front-rear direction. In this way, by controlling the amount of extension of each adjustment screw 5, the relative position of the tool in the left-right direction and the skew angle of the tool can be adjusted. And after the adjustment is finished, the inner side wall of the cutter is always subjected to the propping force action of the adjusting screw 5, so that the fixing reliability is ensured.

In practical application, the first threaded hole 13 and the second threaded hole 14 are extremely easy to wear after being used for a period of time, and are not easy to repair, so that the tool apron body needs to be replaced frequently. For this purpose, the tool holder body 1 is preferably made of high carbon steel, and is subjected to quenching and tempering heat treatment to ensure that the hardness of the threads of the first threaded hole 13 and the second threaded hole 14 is not less than 28 HRC.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
