Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the use of the term knowledge in the specification of the present invention is for the purpose of describing particular embodiments and is not intended to limit the present invention, and the term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-2, a special tool for processing a side hole of a valve body is provided, wherein a hole 104 to be processed is arranged at the side end of the valve body 1, a first positioning hole 101 is arranged at the upper end of the valve body 1, and a second positioning hole 103 and a mistake-proofing hole 102 are arranged at the lower end of the valve body 1.

Please refer to fig. 3-5, a special tool for processing a side hole of a valve body comprises a tool body 2, a placing groove 3 is arranged on the tool body 2, a compression screw 4 is arranged at the upper end of the tool body 2, the compression screw 4 penetrates through the tool body 2 and extends into the placing groove 3, and the compression screw 4 is connected with the tool body 2 through threads. The lower end of the compression screw 4 is connected with the connecting plate 5 through threads. The lower end of the connecting plate 5 is fixed with a pressing pin 6, and the pressing pin 6 is in interference fit with the connecting plate 5. The pressing pins 6 are matched with the first positioning holes 101, and the number of the pressing pins 6 is the same as that of the first positioning holes 101. The inner bottom end of the placing groove 3 is fixed with a mistake-proofing pin 7 matched with the mistake-proofing hole 102. The bottom end is provided with mounting groove 8 in the standing

groove

3, and 8 internal fixations in mounting groove have adjusting nut 9, and adjusting nut 9 upper end is fixed with the lower extreme of pressure spring 10, and pressure spring 10 upper end is fixed with locating pin 11 that floats. A sliding sleeve 12 is fixedly sleeved outside the floating positioning pin 11, a limiting plate 13 is fixedly arranged at the upper end of the sliding sleeve 12, the floating positioning pin 11 extends out of the mounting groove 8, and the number of the floating positioning pins 11 is the same as that of the second positioning holes 103.

The working principle of the utility model is as follows: firstly, taking down the pressing pin 6 and the connecting plate 5, and putting the pressing pin 6 on the connecting plate 5 into the first positioning hole 101 of the valve body 1 and tightly attaching to the upper end face of the valve body 1; the valve body 1 and the connecting plate 5 are placed into the placing groove 3 of the tool body 2 together, the second positioning hole 103 of the valve body 1 is sleeved on the floating positioning pin 11, the valve body 1 is manually pressed downwards to be flatly attached to the bottom surface of the placing groove 3, the center of the second positioning hole 103 of the valve body 1 is automatically aligned by the structure of the floating positioning pin 11 through a taper pin, and after the hole is aligned, the sliding sleeve 12 retracts downwards to enable the bottom surface of the valve body 1 to be flatly attached to the bottom surface of the placing groove 3; and finally, manually wrenching the compression screw 4 until the product is firmly pressed, and starting a lathe to process the product. Because the mistake proofing hole 102 of the valve body 1 is processed in the previous process, if the hole site is not processed in the missing process, the product cannot be put into the tool body 2, and the valve body 1 cannot be flatly attached to the bottom surface, so that the mistake proofing purpose is achieved.
