Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be further described below.

The utility model provides a deep hole drilling clamp structure of an oil sprayer body, which is shown in fig. 1 and comprises a front fixing seat, a rear fixing seat, a left fixing seat and a right fixing seat; the four fixing seats are respectively fixed on the front, back, left and right fixing surfaces of the to-be-processed oil sprayer body 10;

as shown in fig. 2 and 3, the front fixing seat comprises a positioning disk 1, and the middle part of the positioning disk 1 is a processing hole; the guide sleeve 2 is preset in the machining hole, a limit boss is arranged at the tail end of the machining hole, and the compression spring 3 is pre-buried between the tail end of the guide sleeve 2 and the limit boss.

On the connecting surface of the positioning disk 1 and the to-be-processed oil sprayer body 10, a first positioning pin 4 is arranged below the guide sleeve 2, and when the front end surface of the to-be-processed oil sprayer body 10 is fixedly attached to the positioning disk 1, a positioning round hole of the front end surface of the to-be-processed oil sprayer body 10 is sleeved into the first positioning pin 4.

In this embodiment, as shown in fig. 4, the left fixing seat is a connection seat 5 with an "L" shaped cross section, the connection seat 5 includes a first connection surface and a second connection surface, and the first connection surface is fixedly connected with the positioning disk 1 through a second positioning pin 8;

as shown in fig. 5, an adjustable screw pair 6 is inserted on the second connecting surface, and the adjustable screw pair 6 is screwed into a threaded hole of the second connecting surface and then abuts against the left positioning surface of the to-be-processed oil sprayer body 10, and is locked by a nut.
