Abstract
The utility model relates to a positioning groove milling clamp for a plunger sleeve, which comprises a basal body part and a positioning clamp part, wherein, the basal body part comprises a base and a support saddle which are connected fixedly; the positioning clamp part comprises a pull rod, a gasket, an expansion core sleeve, a bushing and a nut; the bushing is arranged inside the support saddle; the pull rod penetrates through the bushing horizontally; in addition, one end of the pull rod is externally sheathed with the expansion core sleeve, the nut is arranged at the other end of the pull rod, and the other end of the pull rod is fixedly connected with the support saddle through the gasket. The positioning groove milling clamp has the benefits as follows: firstly, a basal body is convenient to disassemble, and the integral processing wastes material and is not easy to guarantee the machining precision; secondly, the mesopore clamping is adopted rather than the end surface clamping, so that processing parts are convenient to replace; and thirdly, the expansion core sleeve is additionally arranged on the positioning clamp part, so that the expansion core sleeve needs to be replaced only when various pore diameters are changed.
Description
Technical field
The utility model relates to a kind of plunger bushing and mills the locating slot anchor clamps.
Background technology
Plunger matching parts is one of vitals of locomotive engine, can be divided into multiple series according to the model of engine, and wherein the serial existing market of A type series and P type has the call, and these two kinds of series also derive many kinds according to profile and aperture different.Plunger bushing is the key component of plunger matching parts, and its production emphasis is in metalworking, and even part manufacturer usually runs into the production of multi-varieties and small-batch, and each kind need design processing one cover and mills the locating slot anchor clamps in the past, and was difficult to exchange, and the process-cycle is also long.Process equipment also is a production miller, and power consumption is big.
The utility model content
The utility model provides a kind of plunger bushing simple in structure, easy to operate, that adapt to many variety production to mill the locating slot anchor clamps in order to overcome the above problems.
The technical solution of the utility model is: comprise body portion and location clamping part, described body portion comprises base and bearing, and both are fixedly connected; Described location clamping part comprises pull bar, packing ring, expansion core retainer plate, lining and nut, and lining is arranged in the bearing, and described pull bar level is passed lining, and pull bar one end is with the expanded core cover outward, and the other end is provided with nut and is fixedly connected on the bearing by packing ring.
Also be provided with stop screw on the described bearing, contact with pull bar.
The utility model has the advantages that: 1. matrix is convenient to dismounting, whole processing waste material, and machining accuracy is difficult for guaranteeing; 2. adopt mesopore to clamp, but not the end face clamping, it is convenient to change processing parts; 3. the location clamping part increases the expansion core retainer plate, during the kind varying aperture, as long as change this part.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is base among the figure, the 2nd, and bearing, the 3rd, pull bar, the 4th, expansion core retainer plate, the 5th, lining, the 6th, packing ring, the 7th, nut.
The specific embodiment
Plunger bushing mills the locating slot anchor clamps, comprises body portion and location clamping part, and described body portion comprises base 1 and bearing 2, and both are fixedly connected; Described location clamping part comprises pull bar 3, packing ring 6, expansion core retainer plate 4, lining 5 and nut 7, lining 5 is arranged in the bearing 2, described pull bar 3 levels are passed lining 5, pull bar 3 one ends are with expanded core cover 4 outward, the other end is provided with nut 7 and is fixedly connected on the bearing 2 by packing ring 6, also is provided with stop screw on the described bearing 2, contacts with pull bar 3, transfer when preventing that pull bar 3 from tightening is pressed from both sides not tight.During work, be under the loosening state with the nut 7 of cylinder lever connecting rod 3, to be processed of plunger bushing is inserted in by pull bar 3 left ends, and the plunger bushing large end face contacts the location with lining 5 end faces, turns nut 7, expansion core retainer plate 4 is under the effect of pull bar 3, distending radially, thereby swelling workpiece are after the process finishing, after unclamping nut 7, workpiece can be extracted out easily, change.
