Description

Boats and ships sleeve hole milling frock

Technical Field

The invention relates to the technical field of ship sleeve processing tools, in particular to a ship sleeve hole milling tool.

Background

Tooling, namely process equipment: the clamp is a process device used for rapidly fastening a workpiece to keep a machine tool, a cutter and the workpiece in correct relative positions during processing, is also called a fixture, and can be called a clamp for rapidly, conveniently and safely mounting the workpiece in any process in a broad sense.

In the machinery manufacturing industry, especially in the fields of aerospace, ships and the like, various sleeve products are widely applied, are mainly used at connecting positions of main bodies and accessories, have the functions of certain switching, protection, steering and the like, and have the characteristics of high requirements on product sizes, complex appearance and the like. As shown in fig. 1, when processing the milling bore to the sleeve of preliminary shaping (treating the machined part), preliminary shaping's sleeve integrated into one piece has the positioning disc, evenly distributed has 6 locating holes on the positioning disc, the positioning disc divide into a section of thick bamboo and a lower section of thick bamboo with the sleeve, carry out milling bore man-hour on telescopic last section of thick bamboo, the size of (1), (2), (3) as shown in fig. 2 will be guaranteed, need to guarantee the angle of (5) again, therefore, according to the product characteristics, under the prerequisite that guarantees product quality, efficiency and reliability are high, design one kind can once the clamping accomplish the milling bore processing, the frock that can guarantee size precision again is especially important.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the invention provides a ship sleeve hole milling tool, aiming at improving the processing efficiency on the premise of carrying out hole milling processing on a sleeve and ensuring the precision.

In order to solve the problems, the technical scheme adopted by the invention is as follows:

the utility model provides a boats and ships sleeve hole milling frock, offers in the middle of including mount pad and is used for placing telescopic first through-hole, still offers the second through-hole that is used for fixed mounting hook type bolt and the recess that is used for grafting locating pin on the mount pad, and the nut that hook type bolt was taken from compresses tightly treats the positioning disk upper surface of machined part from the area, and the screw rod and the nut threaded connection of hook type bolt, locating pin are vertical to be passed the positioning disk from the locating hole of taking and are pegged graft perpendicularly in the recess.

The principle of the scheme is as follows:

through placing the sleeve in the first through-hole of mount pad, use the locating pin to pass the locating hole on sleeve integrated into one piece's the positioning disc and pass the grafting and fix the sleeve in the recess, then pass the second through-hole with hook bolt, the nut compresses tightly at telescopic upper surface, passes the screw rod and the nut threaded connection of mount pad, realizes telescopic compressing tightly fixedly, then fixes the mount pad at the machine tool center, and control milling cutter carries out the processing of milling bore to the sleeve.

The beneficial effect that this scheme produced is:

1. through the fixed of locating pin, prevent that the sleeve from rocking about in the course of working.

2. The sleeve is tightly pressed and fixed on the mounting seat through the matching of the hook-shaped bolt and the nut;

3. when adding man-hour, the locating pin combines hook bolt and nut to compress tightly fixedly to the sleeve, adds man-hour and need not adjust telescopic position once more, and the processing of milling holes can be accomplished in fixed compressing tightly once, through cooperation and locking between mount pad, nut, hook bolt, the locating pin, stable in structure, reliable, safety, and can accomplish processing through once fixing, have improved machining efficiency.

Furthermore, a wedge block with an inclined plane inclined at an inclination angle of 15 degrees is fixedly connected to one side of the mounting seat, and a positioning block is fixedly connected to the mounting seat at the opposite end of the positioning block. Through fixing the mount pad on 15 degrees inclination voussoirs for when needing to fix the work piece of treating to process on the lathe through the mount pad in the hole milling processing, the sleeve is the state of 75 degrees slopes, in order to ensure to process the precision that the finished product satisfies the precision of size and position after the work piece of treating to process, need not adjust the position of the work piece of treating to process again or the angle in the course of working, improved process rate.

Furthermore, the second through holes are symmetrically arranged on two sides of the mounting seat and close to one side of the positioning block. When the workpiece to be processed is pressed and fastened, the positioning disc of the workpiece to be processed is pressed and fixed by fixing the hook-shaped bolts in the second through holes on two sides of the mounting seat, and the second through holes are symmetrically arranged on the mounting seat, so that the pressing force is more uniform, and the workpiece to be processed is more stable.

Furthermore, the grooves and the second through holes are symmetrically arranged on two sides of the mounting seat in parallel. The positioning pins are inserted into the symmetrical positions of the mounting seat to position the workpiece to be processed, so that the stability of the workpiece to be processed on the mounting seat is increased, and the workpiece to be processed is prevented from shaking left and right in the processing process.

Further, the length of the hook bolt is greater than the thickness of the mounting seat. The hook-shaped bolt can penetrate through the mounting seat to be connected with the nut to realize fixation.

Furthermore, the diameter of the positioning pin is consistent with the diameter of the positioning hole and the width of the groove. When the positioning pin can penetrate through the positioning hole of the positioning disc and is vertically inserted in the groove, the positioning pin cannot shake in the groove, the stability of fixing the workpiece to be processed on the mounting seat is improved,
