[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0029] like Figures 1 to 3 As shown, this embodiment provides a machine tool processing positioning device 50, including a base 10, a rotating shaft 20, a circular lower positioning plate 30 and a circular upper positioning plate 40, wherein the base 10 is fixedly mounted on the table top of the processing platform of the machine tool, and the fixed installation method can select a variety of different case methods according to the style of the processing platform of the machine tool, mainly for the convenience of processing. The rotating shaft 20 is rotatably mounted on the base 10, wherein a fixing device is installed between the rotating shaft 20 and the base 10, and the fixing device is used to fix the base 10 and the rotating shaft 20 to prevent the rotating shaft 20 from rotating during the drilling process. Preferably, as Figure 3 As shown, the fixing device includes a pin rod 60, a first pin hole is provided on the base 10, and a plurality of second pin holes are provided at the position where the rotating shaft 20 is rotatably connected to the base 10, and one end of the pin rod 60 can pass through the first pin hole and then be inserted into the second pin hole.

[0030] In this embodiment, the lower positioning plate 30 is fixedly mounted on the rotating shaft 20, and the lower positioning plate 30 is coaxially mounted with the rotating shaft 20. The lower positioning plate 30 is used to support the workpiece. At the same time, a plurality of lower through holes are pre-set on the lower positioning hole. The selection of the position of the lower through hole can be determined according to the position requirements of different workpieces that need to be punched.

[0031] The upper positioning plate 40 is coaxially sleeved on the rotating shaft 20, and the upper positioning plate 40 is located above the lower positioning plate 30. The upper positioning plate 40 is detachably connected to the lower positioning plate 30 through a positioning device 50. A plurality of upper through holes 44 are provided on the upper positioning plate 40. Similarly, the positions of the upper through holes 44 can be determined according to the requirements of the positions where holes need to be punched in different workpieces. Therefore, after the upper positioning plate 40 and the lower positioning plate 30 are installed, the upper through holes 44 and the lower through holes are coaxially arranged, and the workpiece to be processed is fixedly clamped between the upper positioning plate 40 and the lower positioning plate 30.

[0032] In this embodiment, three lower ears 31 are evenly distributed on the periphery of the lower positioning plate 30, and the lower ears 31 are provided with lower ear 31 through holes. Three upper ears 41 are evenly distributed on the periphery of the upper positioning plate 40, and the upper ears 41 are provided with upper ear 41 through holes. The upper ear 41 through holes are coaxially installed with the upper ear 41 through holes, and the locking device fixes the upper positioning plate 40 with the lower positioning plate 30 through the upper ear 41 through holes and the lower ear 31 through holes. Preferably, the locking device includes a threaded rod 51 and a nut 52, and one end of the threaded rod 51 passes through the upper ear 41 through holes and the lower ear 31 through holes in sequence and then is screwed with the nut 52.

[0033] In addition, in this embodiment, a plurality of upper circular rings 43 are provided at the bottom of the upper positioning plate 40, and the upper through hole 44 is located between two adjacent upper circular rings 43. A plurality of lower circular rings 32 are provided at the bottom of the lower positioning plate 30, and the lower through hole is located between two adjacent lower circular rings 32. In this way, it is convenient for the operator to calibrate the drill rod before drilling. Before drilling, the drill rod is extended into the corresponding upper through hole 44, and then the drilling machine is started to perform the drilling operation. The lower circular ring 32 can prevent the drill rod from passing through the lower positioning plate 30 and drilling into the base 10 or the processing platform of the machine tool.

[0034] In this embodiment, in order to facilitate the operator's operation and prevent the operator from drilling the wrong hole, a plurality of coaxially arranged circular marking lines 42 are provided on the upper positioning plate 40, and these upper through holes 44 are all arranged on these marking lines 42, so that the operator only needs to determine the marking lines 42.

[0035] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
