Abstract

The invention relates to a tapping machine fixture for a movement nut in a marine diesel engine cylinder. The tapping machine fixture comprises a first fixture body (1), wherein a first clamping hole (1.1) is arranged in the first fixture body (1), and is also sleeved with a second clamping body (2), and the shape and size of the outer side wall of the second clamping body (2) are matched with those of the first clamping hole (1.1); the second clamping body (2) is provided with a second clamping hole (2.1) which is also sleeved with an Nth clamping body for clamping an Nth movement nut, and the shape and size of the outer side wall of the Nth clamping body are matched with those of the previous clamping hole; the Nth clamping is provided with an Nth clamping hole the shape and size of which are matched with those of the outer side wall of the Nth movement nut. The tapping machine fixture can clamp movement nuts of different sizes and does not need to be reinstalled every time.

Description

Movement nut tooth machining unit fixture in marine diesel cylinder

Technical field

The present invention relates to movement nut tapping technical field in marine diesel cylinder, is specifically movement nut tooth machining unit fixture in a kind of marine diesel cylinder.

Background technology

At present, there is a kind of tonnage to reach the marine low speed diesel engine of 1850t, in the cylinder of this diesel engine, for connecting the connector of piston and piston rod, generally adopt high-quality special steel alloy to be made, integral body is cylindrical shape, two ends are provided with the screw thread that connects use, this motion connector also moves with piston, piston rod when playing connection function, therefore be commonly called as in industry as motion bolt, for the nut of fastening motion bolt, is commonly called as movement nut.

Because of the internal diameter of this movement nut all larger, it is mostly 100mm left and right, have even to have reached 110mm big, therefore when movement nut is carried out to tapping, all need to fix movement nut with a fixture, the lateral wall shape of the endoporus of this fixture and movement nut, size match, and during operation, movement nut are placed in the endoporus of fixture, after fixture is arranged on the holder of tooth machining unit, the screw tap on tooth machining unit just can start movement nut to carry out the processing of internal thread.But because movement nut varies, and the shape of the lateral wall of each fixture, size all match with the endoporus of movement nut, therefore the movement nut of different-diameter is being added to man-hour, just need to change different fixtures, and all will reinstall fixture, time-consuming effort again operates at every turn.

Summary of the invention

Technical problem to be solved by this invention be for above-mentioned the deficiencies in the prior art, provide a kind of can clamping different size movement nut and without movement nut tooth machining unit fixture in the marine diesel cylinder of all reinstalling at every turn.

For solving the problems of the technologies described above, the present invention is by the following technical solutions: comprise first clamp body for first movement nut of clamping, first described clamp body is provided with the lateral wall shape with first movement nut, first clamping hole that size matches, in first described clamping hole, be also set with second clamping body for second movement nut of clamping, the lateral wall of second described clamping body and the shape in first clamping hole, size matches, second described clamping body is provided with the lateral wall shape with second movement nut, second clamping hole that size matches, in second described clamping hole, be also set with N the clamping body for N movement nut of clamping, the lateral wall of N described clamping body and the shape in a upper clamping hole, size matches, N described clamping body is provided with the lateral wall shape with N movement nut, N the clamping hole that size matches.

Described N is 2.

The invention has the beneficial effects as follows: in marine diesel cylinder of the present invention, movement nut tooth machining unit fixture is by the setting of N clamping body, so in use, by extraction, there is no the clamping body needing, the clamping body that remains with use just can be realized the processing to the movement nut of different-diameter, when fixing clamping body, only need the fixedly clamping body of outmost turns just can, other clamping bodies were set in last clamping body just can realize operation, without when the movement nut of different-diameter is operated, one a pair of clamping body is installed fixing, operates simply, easily goes.

Further, N described clamping hole is second clamping hole, and two is a preferred value, can use clamping body as much as possible, and can make again operation become feasible.

Accompanying drawing explanation

Fig. 1 is the main TV structure schematic diagram of movement nut tooth machining unit fixture in marine diesel cylinder of the present invention.

Fig. 2 is the decomposition texture schematic diagram of movement nut tooth machining unit fixture in marine diesel cylinder of the present invention.

Shown in figure of the present invention: 1, first clamp body, 1.1, first clamping hole, 2, second clamping bodies, 2.1, second clamping holes.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the invention will be further described.

Because tooth machining unit is prior art, therefore do not show in the accompanying drawings.

As shown in drawings, movement nut tooth machining unit fixture in marine diesel cylinder of the present invention, comprise first clamp body 1 for first movement nut of clamping, first described clamp body 1 is provided with and the lateral wall shape of first movement nut, first clamping hole 1.1 that size matches.

In first described clamping hole 1.1, be also set with second clamping body 2 for second movement nut of clamping, the lateral wall of second described clamping body 2 and shape, the size in first clamping hole 1.1 match, and second described clamping body 2 is provided with second clamping hole 2.1 that lateral wall shape, size with second movement nut match.In second described clamping hole 2.1, be also set with N the clamping body for N movement nut of clamping, the lateral wall of N described clamping body and shape, the size in a upper clamping hole match, and N described clamping body is provided with N the clamping hole that lateral wall shape, size with N movement nut match.In the present embodiment, described N is 2, and the quantity of described clamping body is two, in first clamping body, is set with second clamping body.

In the present embodiment, described matching refers to matching of size, shape, match both for matched in clearance, when both assemble, just in time can freely put into and can freely take out.

Fixture of the present invention can be realized the processing to the movement nut of two kinds of different-diameters, when needs add man-hour with first clamping body, second clamping body taken out, after first clamping body being fixed on the holder of tooth machining unit, just can start movement nut to carry out tapping, and need to process the movement nut of other diameter with second fixture time, this second clamping body is sleeved in the clamping hole of first clamping body and just can processes second movement nut.

Fixture of the present invention can also arrange the clamping body of a plurality of mutual sheathing, thereby realize the processing to the movement nut of different-diameter, fixture of the present invention because of volume and weight all very large, solve each clamping for a long time and needed to repeat to be fixedly mounted on the trouble on tooth machining unit holder, greatly facilitate operation, effectively improved the efficiency of tapping, and it is very simple, convenient to operate.In addition, the fixture of mutual sheathing is collected also very convenient, space-saving, and is convenient to whole preservation.
