DETAILED DESCRIPTION

[0023] The embodiment of the utility model provides a new rotor pressure plate drilling tool 100, solved in prior art to pressure plate drilling, need through artificial first to the pressure plate that cut does mark, then through artificial fixed pressure plate that does mark on the bench drill and carries out drilling, whole process step is complicated, time -consuming is longer, and the technical problem that drilling position is not accurate, realized greatly promoted the efficiency and precision's technical effect that rotor pressure plate drilled.

[0024] The technical scheme in the embodiment of the utility model solves the above problems, and the general idea is as follows: a plurality of stacked pressure plates 5 are placed in the pressure plate opening groove 22 of the pressure plate fixing seat 2, and then the pressure plate 5 is locked by the pressure plate side cover plate 3 and the pressure plate upper cover plate 4, the drill bit of the bench drill passes through the second circular hole 41 of the pressure plate upper cover plate 4 and the first circular hole 11 of the drilling base 1, and the plurality of pressure plates 5 can be drilled in batches, and the positioning of the first circular hole 11 and the second circular hole 41 can avoid drilling deviation, thereby improving the efficiency and precision of the rotor pressure plate drilling.

[0025] In order to better understand the above technical scheme, the above technical scheme will be described in detail below in conjunction with the drawings and specific embodiments of the specification.

[0026] Please refer to Figures 1 to 7 The preferred embodiment of the utility model discloses a new rotor pressure plate drilling tool 100, which comprises:

[0027] A drilling base 1 is provided with a first circular hole 11 and three first locking holes 12 from top to bottom; the drilling base 1 is used for bearing the drilling tool 100; the first circular hole 11 is used for drilling the pressure plate 5 by the drilling bench (not shown); the first locking hole 12 is used for installing the pressure plate fixing seat 2;

[0028] A pressure plate fixing base 2 has three first locking attachments 21 at its bottom and a pressure plate opening groove 22 at its top. A second locking attachment 23 is located at the rear of the top left and right sides of the pressure plate opening groove 22, and a sliding groove 24 is located at the front of the left and right sides inside the groove. The pressure plate fixing base 2 is mounted on a drilling base 1 via the first locking attachments 21 and first locking holes 12. The first locking attachments 21 are inserted into the first locking holes 12 to fix the pressure plate fixing base 2. The pressure plate opening groove 22 is used to accommodate stacked pressure plates 5 and to limit the position of the pressure plates 5. The second locking attachments 23 are inserted into the second locking holes 42. The sliding groove 24 is used to install the pressure plate side cover plate 3.

[0029] A pressure plate side cover 3 is slidably connected to the pressure plate fixing seat 2 via the slide groove 24, and has an extension 31 at the top end for pressing the pressure plate 5.

[0030] A pressure plate cover plate 4 has a second circular through hole 41 and two second locking holes 42 from top to bottom; the second circular through hole 41 is located in the middle of the two second locking holes 42 and is directly above the first circular through hole 11; the pressure plate cover plate 4 is installed on the top of the pressure plate fixing seat 2 through the second locking holes 42 and the second locking attachments 23; the second circular through hole 41 is used for drilling holes in the pressure plate 5 with a drilling table; the pressure plate cover plate 4 is used to press the pressure plate 5 together.
