Abstract
Description
Technical Field
[0001] The utility model relates to a processing tool, in particular to a processing tool for processing two adjacent eccentric arcs on a locking sleeve of a mooring rigging, and belongs to the technical field of tool fixtures. Background Art
[0002] The helicopter mooring equipment is a special equipment to ensure the safe mooring of shipborne helicopters on the take-off and landing platform. After the helicopter lands, when the ship sways or bumps, the use of the helicopter mooring equipment can effectively prevent the helicopter from displacement and overturning. The helicopter mooring equipment consists of a mooring rigging and a mooring seat. The caliper of the front attachment of the mooring rigging is connected to the helicopter mooring ring, with a high-strength chain in the middle. The mooring hook of the rear attachment of the mooring rigging is hooked on the mooring seat on the deck, thereby realizing the mooring of the helicopter. The locking sleeve on the mooring rigging plays the role of quickly opening and closing the caliper.
[0003] like Figure 1 As shown, taking a 6mm chain diameter high-strength chain mooring sling as an example, the inner special-shaped countersunk hole of the locking sleeve 10 includes two mutually symmetrical groups of eccentric arcs and a center arc 101, each group of eccentric arcs includes a first arc 102 (radius R1=7.5mm) and a second arc 103 (radius R2=28.6mm) tangent thereto, and the center of the second arc 103 is respectively located on the perpendicular bisector of the line connecting the centers of the first arcs 102. Due to the complex structure of the inner special-shaped countersunk hole of the locking sleeve, it is very difficult to locate and align during processing, and it is often necessary to repeatedly align and locate multiple times to complete the processing of its inner hole, which not only has low processing efficiency, but also has large cumulative errors of parts and high scrap rate, which invisibly increases production costs. Utility Model Content
[0004] The utility model aims to provide a processing tool for a mooring rigging locking sleeve which has the advantages of simple structure, convenient operation, accurate and reliable positioning.
[0005] The utility model is realized through the following technical solutions:
[0006] A processing tool for a mooring rigging locking sleeve comprises a base and a slide; the bottom flange of the base is fixedly supported on the turntable of a milling machine worktable, and a sunken rectangular sliding cavity is provided in the middle of the base; the lower part of the slide is supported in the rectangular sliding cavity, one side of the slide is against one side of the rectangular sliding cavity, the other side of the slide is tightened by bolts on one side of the base, and the other two sides of the slide are respectively pressed by pressure plates on both sides of the top of the base; the locking sleeve is sleeved in the mounting hole in the middle of the slide, and is positioned by the positioning column at the bottom of the mounting hole, and the top of the locking sleeve is pressed by several pressure plates.
[0007] The purpose of the utility model can be further achieved by the following technical measures.
[0008] In the aforementioned processing tooling for the mooring rigging locking sleeve, the other two sides of the slide seat are respectively provided with steps, and the pressure plates on both sides of the top of the base are respectively pressed tightly on the corresponding steps.
[0009] In the aforementioned processing tooling for the mooring rigging locking sleeve, the sliding distance of the slide seat is the center distance L between the two second arcs on the locking sleeve.
[0010] In the aforementioned processing tooling for the mooring rigging locking sleeve, the rotation center of the turntable coincides with the center of the second arc on the locking sleeve.
[0011] In the aforementioned processing tool for the mooring rigging locking sleeve, a positioning pin is provided at the bottom of the base.
[0012] The utility model has a simple structure, low cost and convenient operation. When processing the inner special-shaped countersunk hole of the locking sleeve, the tool center can be converted by rotating the rotary disk of the milling machine table, moving the milling machine table and moving the slide seat, and the rotary center of the rotary disk can be adjusted to the center of the next arc to be processed, thereby completing the processing of two groups of eccentric arcs. The utility model can complete the processing of two groups of eccentric arcs by clamping once and positioning twice, which not only has high work efficiency, but also has stable and reliable clamping, accurate positioning, high processing accuracy and small processing error, thereby ensuring the processing quality of the product.

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0020] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model includes a base 1 and a slide 2. The bottom flange of the base 1 is fixedly supported on the turntable 3 of the milling machine table by fasteners. A sunken rectangular slide cavity 11 is provided in the middle of the base 1, and a positioning pin 12 is provided at the bottom. The slide 2 is a square structure. The lower part of the slide 2 is supported in the rectangular slide cavity 11. The side length of the lower part of the slide 2 matches the short side length of the rectangular slide cavity 11. The right side of the slide 2 abuts against the short side of the right side of the rectangular slide cavity 11. The left side of the slide 2 is tightened by the bolt 13 on the left side of the base 1. The front and rear sides of the slide 2 are respectively provided with steps 21, and the pressure plates 14 on both sides of the top of the base 1 are respectively pressed on the corresponding steps 21. The locking sleeve 10 is sleeved in the mounting hole 22 in the middle of the slide 2, and is positioned by the positioning column 23 at the bottom of the mounting hole 22. The top of the locking sleeve 10 is pressed by two pressure plates 24. The sliding distance of the slide 2 is the center distance L of the two second arcs 103 on the locking sleeve, as shown in FIG. Figure 2 As shown, the rotation center of the rotating disk 3 coincides with the center of the second arc 103 on the locking sleeve 10 that is tangent to the left first arc 102 .
[0021] The processing of the utility model is as follows:
[0022] The locking sleeve 10 is placed in the mounting hole 22 of the slide 2 and positioned by the positioning column 23 at the bottom center of the slide mounting hole 22, and the top two sides of the locking sleeve 10 are pressed by the pressing plate 24. Figure 2 As shown, the milling cutter 4 with a diameter of 15 mm is inserted into the inner special-shaped countersunk hole of the locking sleeve 10, and its center line is coincident with the center line of the first arc 102 on the left side of the locking sleeve, and the first arc 102 on the left side is milled to the size of the drawing. Then the turntable 3 is manually turned back to rotate 90° counterclockwise. During this process, the milling cutter 4 rotates relatively along the second arc 103 tangent to the first arc 102 on the left side, thereby completing the processing of the second arc 103 tangent to the first arc 102 on the left side. At this time, the milling cutter 4 is located at the tangent point of the second arc 103 and the center arc 101, and the milling cutter 4 is withdrawn. Loosen the tightening bolt 13 on the left side of the base 1, slide the slide 2 to the left to the left side of the slide cavity 11, and tighten it with the tightening bolt 13 on the right side of the base 1. At the same time, move the milling machine worktable, move the center of the milling cutter 4 to the center of the first arc 102 to be processed on the right side, mill the first arc 102 on the right side to the size of the drawing, turn the turntable 3 by hand, and use the same method to mill out the second arc 103 tangent to the first arc 102 on the right side.
[0023] In addition to the above-mentioned embodiments, the present invention may also have other implementation modes. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
