Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, the tool for boring and milling the screw rod of the screw pump comprises a bottom plate 1, a fixed seat 2 fixed on the top of the bottom plate 1, and a workpiece shaft 5 arranged in the fixed seat 2; the fixed seat 2 is hollow and provided with a cavity 21, and a fixed plate 22 and a positioning plate 23 are respectively arranged on two sides of the cavity 21; a first through hole 221 is formed in the outer surface of the fixing plate 22, and a clamping jaw 3 is further connected to the outer surface of the fixing plate 22 in a sliding manner; a second through hole 231 is formed in the positioning plate 23, and the first through hole 221 and the second through hole 231 are coaxial; the workpiece shaft 5 comprises a processing section 51 and a fixing section 52; the diameter of the first through hole 221 is larger than that of the fixed section 52, the diameter of the fixed section 52 is larger than that of the second through hole 231, and the diameter of the second through hole 231 is larger than that of the processing section 51; and the bottom plate 1 is provided with a feeding plate 4.

The working principle is as follows: the screw rod processed by the device is obtained by boring and milling the processing section 51, the workpiece shaft 5 meeting the shaft diameter requirement is placed in the fixed seat 2, and the non-meeting workpiece shaft needs to be roughly turned. The workpiece shaft 5 is placed on the feeding plate 4 and is sent into the first through hole 221, because of the diameter difference, the shaft shoulder naturally props against the positioning plate 23, at this time, the clamping jaws 3 are moved to fix the fixing section 52 of the workpiece shaft 5, and the cutter is adjusted to a proper processing position.

The top surface of the upper material plate 4 is a cylindrical surface, and the radian diameter of the upper material plate 4 is larger than that of the first through hole 221. The cylindrical surface is used for centering the workpiece shaft 5, so that the workpiece shaft is prevented from moving on a plane and falling out.

The feeding plate 4 is arranged on one side of the fixing plate 22; the top surface of the upper material plate 4 is higher than the lowest point of the first through hole 221. This arrangement allows the workpiece spindle 5 to enter directly into the first through hole 221 without hitting the fixing plate 22. By using the feeding plate 4, the positioning and fixing of the workpiece shaft 5 are faster and more accurate, and the working time is saved.

The shaft shoulder of the fixing section 52 contacts the inner side surface of the positioning plate 23.

A plurality of third through holes 232 are formed in the positioning plate 23, and the third through holes 232 are communicated with the cavity 21. This arrangement helps to dissipate heat.

And a cutter shaft 6 and a boring and milling cutter 7 fixed at the bottom of the cutter shaft 6 are arranged above the processing section 51. The structure of the device is improved.
