The invention is further described below with reference to the accompanying drawings.
Referring to fig. 1, the simple alignment jig of the present invention is used for rough machining of motor casing blanks. The rough machining of the motor shell blank is provided with a cylinder body 01, an inner hole is coaxially arranged in the cylinder body 01, and one end of the cylinder body 01 is integrally and vertically connected with an upper end face 02 of an outer circle.
Please refer to fig. 2 and fig. 3 in combination. The invention relates to a simple correction clamp, which comprises a table frame 1, a rotary workbench 4, a correction needle 6 and a plurality of spiral pressing mechanisms 11. The rotary table 4 is horizontally arranged and can be rotatably arranged on the table frame 1 along a vertical rotating shaft by 360 degrees. Three outer circle positioning seats 9 are fixedly connected to the rotary workbench 4. The three outer circle positioning seats 9 are in triple rotational symmetry about the vertical rotation shaft. The three positioning bolts 10 are in threaded connection with the three outer circle positioning seats 9 in a one-to-one correspondence manner, and the heads of the positioning bolts 10 horizontally point to the vertical rotating shaft.
The plurality of screw pressing mechanisms 11 are arranged on the rotary table 4 around the vertical rotating shaft at intervals, and are used for pressing the upper end face 02 of the outer circle downwards on the rotary table 4. The correction needle 6 is provided above the table frame 1 so as to be vertically slidable. One end of the correction needle 6 faces the rotary table 4 side. The plurality of screw pressing mechanisms 11 may be three or more, which are offset from the three outer circumferential positioning seats 9 in the circumferential direction of the rotary table 4.
When the simple correction clamp of the embodiment is used, the motor casing blank is placed on the rotary workbench 4, and the correction needle 5 is adjusted to enable one end to be approximately close to a position on the upper edge of the inner hole of the motor casing blank. The rotary table 4 is manually rotated, the motor casing blank rotates along with the rotary table, and a certain deviation is generally generated between the rotation contour line of the inner hole of the motor casing blank and the close point of one end of the correction needle 5 in the radial direction (the coaxiality of the inner hole of the motor casing blank and the rotary table is poor). At this time, the positioning bolt 10 of the outer circle positioning seat 9 is adjusted to abut against the outer wall of the cylinder body of the motor casing blank, so that the motor casing blank is coaxially aligned on the rotary workbench 4, and when the radial deviation is adjusted to be stable (the operator observes through naked eyes), the coaxiality of the motor casing blank and the rotary workbench 4 can be confirmed. The upper end face 02 of the outer circle is then pressed down onto the rotary table 4 by the screw pressing mechanism 11. And then the rotary workbench 4 and the motor shell blank are dismounted together, and are hung on a workbench of a lathe to be compressed again, so that the motor shell blank positioning and clamping is completed.
When the next motor casing blank needs to be clamped, one of the positioning bolts 10 is loosened, then the previous motor casing blank is dismounted from the rotary workbench, and then the next motor casing blank is mounted on the rotary workbench 4. And locking the positioning bolts of the backing plate, so that the positioning bolts and the other two positioning bolts lock the next motor shell blank on the rotary workbench in a positioning way. Because the relative positions of the three positioning bolts are unchanged, the coaxiality of the front and rear motor shell blanks relative to the workbench of the rotary workbench and the workbench of the lathe is kept good.
The simple correction clamp of the embodiment only needs to correct the shell blank of the same model once, and the motor shell blank is clamped twice without correction, so that the simple correction clamp is simple to manufacture and convenient to use, and saves time.
In other embodiments, in order to avoid that the motor housing blank phase and the rotary table 4 rotate together to influence the operation of an operator when the screw compressing mechanism 11 is locked, the simple correction clamp may further comprise a positioning pin mechanism 2 for positioning the rotary table 4 in a circumferential rotation relative to the table frame 1.
Referring to fig. 4, the positioning pin mechanism 2 has a vertically disposed and resettable positioning pin 21, and the positioning pin 21 is movably disposed on the table frame 1.

The connecting rod 25, the connecting block 26, the positioning pull pin 21 and the table frame 1 form a rocker slider mechanism. The rotating shaft pedal 28 is fixedly connected with the connecting block 26.
Thus, when the operator operates, the pedal is controlled by feet to further control the positioning pull pin 21, so that two hands can be released for correction and compaction operation, and the operation is more convenient.
Specifically, the positioning pin mechanism 2 further includes a compression spring 22, a positioning pin seat 23, a pin seat cover 24, and a connecting rod 25. The locating pin seat 23 is fixed on the table frame 1. The positioning pin 21 is inserted in the positioning pin seat 23 in a vertically movable manner. The lower end of the positioning pull pin 21 is penetrated with a pull pin seat cover 24. The pull pin seat cover 24 is fixedly connected with the lower end of the positioning pull pin seat 23. The lower end of the compression spring 22 abuts against the detent pin seat 23.

The rotating shaft pedal 28 is rotatably arranged on a rotating shaft pedal support 27, and the rotating shaft pedal support 27 is fixedly connected with the table frame 1.
Thus, when an operator steps on the pedal by foot and releases the pedal after correction, the positioning pull pin 21 is driven by the restoring force of the compression spring 22 to upwards penetrate through the pull pin hole of the rotary workbench 4, and further the motor shell blank is limited to rotate along with the rotary workbench during the pressing operation. When the positioning pull pin 21 passes through the pull pin hole, the rotary workbench 4 cannot rotate, and at the moment, the motor shell blank can be pressed.
