Abstract
The utility model relates to a ruler support which is employed on an external micrometer for overcoming the shortcomings of the prior external micrometers of instable quality and high manufacturing cost. The utility model comprises a ruler support 1, which consists of a surface layer 2 and a reinforcing rib plate 3 in the surface layer 2. The utility model can be applied in the external micrometer due to the smooth surface, stable quality, few processing procedures, high production efficiency and low manufacturing cost.
Description
The utility model relates to a kind of chi frame that uses on outside micrometer.
Outside micrometer is a kind of important measurer that length (particularly external diameter) is measured that carries out, and it mainly comprises chi frame, gage button, fixed sleeving, microdrum, device for measuring force, micrometric screw, locking device and heat-proof device.The chi frame is archwise substantially, and its end has the gage button installation sleeve, and the other end has the fixed sleeving installation sleeve.Existing outside micrometer chi frame mainly contains two kinds, and a kind of is to adopt cast iron or spheroidal-graphite cast iron to make, and another kind is to adopt steel plate to make.Adopt the outside micrometer chi frame of cast iron or spheroidal-graphite cast iron manufacturing at first will utilize conventional cast or hot investment casting manufacturing blank, then blank is carried out Ageing Treatment, carry out machine cut processing at last, artificial polishing surface and correction corner.This outside micrometer chi frame qualified casting is lower, defectives such as pore, sand holes appear in surface and inside sometimes, the machine cut manufacturing procedure is various, and manual processing is more, thereby production efficiency is lower, surface ratio is more coarse, quality is unstable, manufacturing cost is higher.Adopt the outside micrometer chi frame of steel plate manufacturing at first steel plate will be cut into strip, adopt surface grinding machine that grinding is carried out on two planes of strip steel plate, adopt spark cutting machine strip steel plate to be cut into the shape of chi frame again, weld fixed sleeving installation sleeve and gage button installation sleeve then respectively at its two ends, bore boring fixed sleeving mounting hole and gage button mounting hole, at last the corner is manually polished and revised on the surface.There is the shortcoming that manufacturing procedure is various, production efficiency is lower, surface ratio is more coarse, quality is unstable, manufacturing cost is higher equally in this outside micrometer chi frame.
The purpose of this utility model is to provide a kind of any surface finish, stay-in-grade outside micrometer chi frame, its low cost of manufacture.
The purpose of this utility model is achieved in that outside micrometer chi frame, comprises chi frame 1; Its special character is: chi frame 1 has top layer 2 and is positioned at the reinforcement gusset 3 on top layer 2.
Chi frame 1 is archwise substantially, and an end has the gage button installation sleeve, and the other end has the fixed sleeving installation sleeve.The extrusion process manufacturing can be adopted in top layer 2, and its material generally adopts aluminium alloy, will strengthen gusset 3 in the press casting procedure and be embedded in the top layer 2, and top layer 2 and reinforcement gusset 3 are integral.Strengthen gusset 3 general employing steel plate manufacturings, it is used to improve the physical strength of chi frame 1 as the inner core of chi frame 1.Strengthen generally also archwise substantially of gusset 3.
Has combined hole 4 on the reinforcement gusset 3 of the present utility model.
In the process on die casting top layer 2, the die-casting material on top layer 2 can pass the combined hole of strengthening on the gusset 34, and the top layer 2 of strengthening gusset 3 both sides is fused by combined hole 4 and periphery, has improved top layer 2 and the firm degree of strengthening combining between the gusset 3.
Has heat-proof device fixed orifice 5 on the chi frame 1 of the present utility model.
Heat-proof device fixed orifice 5 is used on chi frame 1 heat-proof device being installed.
Have the hole 6 coaxial on the reinforcement gusset 3 of the present utility model with heat-proof device fixed orifice 5.
The diameter in hole 6 is greater than the diameter of heat-proof device fixed orifice 5, and the inside surface in hole 6 is covered by top layer 2.
The utility model be because the die-casting material manufacturing can be adopted in top layer 2, though the physical strength of die-casting material is lower, adopts the outside surface on the top layer 2 that extrusion process makes bright and clean, do not need to carry out machine cut processing and the apparent size unanimity is processed in artificial polishing.The utility model can adopt the higher steel manufacturing of physical strength owing to strengthen gusset 3, improved physical strength of the present utility model, 0～25mm and two kinds of specifications of 25～50mm, its pulling force distortion is less than 2 μ m, 50～75mm and two kinds of specifications of 75～100mm, its pulling force distortion is less than 3 μ m.Compare with the outside micrometer chi frame that adopts the steel plate manufacturing with the outside micrometer chi frame of existing employing cast iron or spheroidal-graphite cast iron manufacturing, any surface finish of the present utility model, steady quality, its manufacturing procedure is less, and production efficiency is higher, low cost of manufacture.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Fig. 2 is the A-A cut-open view among Fig. 1.
Fig. 3 is the B-B cut-open view among Fig. 1.
Fig. 4 is a front view of strengthening gusset 3 among Fig. 2 and Fig. 3.
Fig. 5 is a left view of strengthening gusset 3 among Fig. 2 and Fig. 3.
To shown in Figure 5, present embodiment is a kind of outside micrometer chi frame as Fig. 1, and it comprises chi frame 1, and chi frame 1 has top layer 2 and is positioned at the reinforcement gusset 3 on top layer 2.Chi frame 1 is archwise substantially, and its end has and top layer 2 all-in-one-piece gage button installation sleeves 7, and the other end has and top layer 2 all-in-one-piece fixed sleeving installation sleeves 8.Strengthen the inner core of gusset 3 as chi frame 1, it is archwise substantially.Two corners strengthening gusset 3 respectively have between 6, two holes 6, a hole and have 7 combined holes 4, and the place respectively has two combined holes 4 near two ends.The top layer 2 of strengthening gusset 3 both sides is connected as a single entity by combined hole 4 and periphery.Two corners of chi frame 1 respectively have a heat-proof device fixed orifice 5, and hole 6 is coaxial with heat-proof device fixed orifice 5.The diameter in hole 6 is greater than the diameter of heat-proof device fixed orifice 5, and the inside surface in hole 6 is covered by top layer 2.
The reinforcement gusset 3 of present embodiment adopts cold-rolling steel-plate punch to be shaped, and through suitable processing.The material selection aluminium alloy on top layer 2 (this aluminium alloy should have good stable, skin hardness HB110 °～120 °) adopts die casting machine and die casting casting forming.At first will strengthen putting into after gusset 3 preheatings position location of the die cavity of die casting, the pressure matched moulds.The aluminium alloy of fusing is expelled in the die casting, after slow cooling, strengthens gusset 3 and be wrapped in wherein, and become one, cast out gage button installation sleeve 7 and fixed sleeving installation sleeve 8 simultaneously with top layer 2 by top layer 2.At last, the chi frame 1 that is shaped is taken out in die sinking, processes gage button mounting hole 9, fixed sleeving mounting hole 10 and locking screw 11.According to concrete needs, the outside surface on top layer 2 can carry out kinds of surface and handle for example chromium plating, plastic-blasting, baking vanish, electroless plating look etc.
