Abstract
The utility model provides a high-efficiency clamp for numerical control electric spark punching of a fuel injector bar, which is characterized in that: the high-efficiency clamp mainly comprises a base and a pressure plate; the base is provided with groove for placing workpieces; one end of the pressure plate is fixed on the base through a screw, and the other end is fixed on a stud of the base through a nut; and quick compaction is realized through rotating the pressure plate. The high-efficiency clamp for numerical control electric spark punching of the fuel injector bar according to the utility model has the following advantages: high mounting/detachment speed, high positioning speed, high alignment speed and high machining efficiency.
Description
Technical field
The utility model relates to the numerical control electric spark perforating clamp.
Background technology
The main position of oil spout bar processing is a nozzle opening.The aperture of nozzle opening is very little, generally at φ 0.3 ~ 0.8mm, has the flow distribution requirement, and its status requirement is higher, and mostly material is high temperature alloy.If adopt the common hole that drills and reams, because drill bit is thin, frangible, and also burr is difficult to clean out after the boring, causes the instability of oil spout bar flow, in case burr comes off, flow will suddenly change, and directly influences the indoor temperature of afterbunring.And electric spark-erosion perforation can fundamentally be eliminated above-mentioned two kinds of unfavorable factors.But the oil spout component of rod category is bigger in batches, and technical conditions require high.Each punching all need be rule earlier; Clamping repeatedly could be accomplished whole all processing small holes of oil spout bar, can't guarantee the status requirement between the part aperture like this, and uniformity each other is very poor; Once can only process one; Working (machining) efficiency is lower, and all the time, oil spout bar electric spark-erosion perforation all is the bottleneck factor of restriction house steward's production cycle.
Summary of the invention
The purpose of the utility model is to provide a kind of High efficient clamp that is used for the punching of oil spout component of rod category numerical control electric spark.
The utility model provides a kind of efficient oil spout bar numerical control electric spark perforating clamp; It is characterized in that: mainly comprise base and pressing plate; Base is provided with the groove of laying workpiece; One end of pressing plate is screwed on base, and the other end of pressing plate is fixed on nut on the double-screw bolt of base, realizes compressing fast through rotating pressing plate.
The efficient oil spout bar numerical control electric spark perforating clamp that the utility model provides can be shaped on the hole in the groove of its base, is inserted with alignment pin in the hole, so that oil spout bar location.
The efficient oil spout bar numerical control electric spark perforating clamp that the utility model provides, its double-screw bolt can be fixed on the base with keeper, causes that pressing plate is loosening in order to avoid double-screw bolt rotates.
The efficient oil spout bar numerical control electric spark perforating clamp that the utility model provides, the quantity of the quantity in hole and alignment pin can be 2 ~ 100 on its base, to improve perforating efficiency.
The efficient oil spout bar numerical control electric spark perforating clamp that the utility model provides can have positioning reference on its base, to be implemented in quick location and the centering on the numerically controlled discharge machine.
The efficient oil spout bar numerical control electric spark perforating clamp that the utility model provides, its advantage is: loading and unloading are fast, the location is fast, centering is fast, and working (machining) efficiency is high.
Description of drawings
Fig. 1 is the structural representation of efficient oil spout bar numerical control electric spark perforating clamp.
The specific embodiment
Embodiment 1
Efficient oil spout bar numerical control electric spark perforating clamp, its structure is as shown in Figure 1, comprises base 1 and pressing plate 2; Base 1 is provided with the angle that 24 grooves laying workpiece are confirmed oil spout bar 8; All be shaped on the hole in the groove, be inserted with alignment pin 3 in the hole, totally 24 alignment pins 3; The upper end external diameter of alignment pin 3 and the hole precision-fit of oil spout bar 8; One end of pressing plate 2 is fixed on the base 1 with screw 4, and the other end of pressing plate 2 is fixed on wing nut 5 on the double-screw bolt 6 of base 1, and double-screw bolt 6 usefulness keepers 7---screw is fixed on the base 1; A side of base 1 is flatness and is the datum level of 0.01mm to the perpendicularity of bottom surface, the perpendicularity of pair bottom surface is arranged on the base 1 and is the datum hole of 0.02mm to the position degree of datum level.
