Abstract
The utility model discloses a connecting structure for an ejector rod of a wheel hub casting machine. The connecting structure comprises an ejector rod and an ejector rod base, wherein a clamping groove is formed circumferentially in the lower end of the ejector rod; a through hole is formed in the ejector rod base; and spring pins matched with the clamping groove are arranged in the through hole. According to the connecting structure, the ejector rod and the ejector rod base are connected through the clamping groove and the spring pins, so that the assembly and disassembly efficiency is greatly improved, in addition, the labor intensity is reduced, the manufacturing cost of wheel hubs is reduced, and the economic benefit of an enterprise is increased.
Description
Technical field
The utility model relates to wheel hub casting machine field, is specifically related to a kind of syndeton of wheel hub casting machine push rod.
Background technology
Wheel hub is that vehicle is for connecting the parts of tire and axle, current wheel hub can be divided into three kinds of one piece casting type, Integral forge type and combined types manufacturing process, one piece casting type wheel hub is that current manufacturing cost is minimum, and its output accounts for 90% left and right of wheel hub total growth.The manufacture process of one piece casting type wheel hub is, liquid aluminium alloy is poured into into casting mould, treats that liquid aluminium alloy is solidified as solid-state wheel hub blank, the wheel hub blank demoulding taken out cooling, then carries out the fine finishining such as deburring, polishing and processes, and finally obtains finished product; Wheel hub casting mould is comprised of mold and bed die two parts, and mold is buckled on bed die, first mold is risen separatedly with bed die during the demoulding, and wheel hub blank is connected on bed die, and then the push rod jack-up that makes progress, makes wheel hub blank depart from from bed die.The wheel hub of corresponding different size on the tip-lever support of a current chaptrel hub casting machine, even circumferential along different-diameter is provided with a plurality of screwed holes, push rod lower end is threaded connection in screwed hole, for avoiding the push rod on different circumference, mutually interfere, the wheel hub of each size all needs dismounting push rod to adjust position adding man-hour, workload is large, and efficiency is low.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of syndeton of wheel hub casting machine push rod, and the push rod that can solve existing wheel hub casting machine is threaded connection in tip-lever support, causes the workload of dismounting push rod large, efficiency is low.
The utility model is achieved through the following technical solutions:
A wheel hub casting machine push rod syndeton, comprises push rod and tip-lever support, and described push rod lower end edge is circumferentially with draw-in groove, and described tip-lever support is provided with through hole, is provided with the spring catch matching with draw-in groove in described through hole.
Further improvement of the utility model scheme is, described through-hole wall is provided with the cavity of closing in, and the plunger of spring catch stretches into through hole inner chamber from the closing in of cavity, between the back side of described plunger and cavity wall, is provided with spring.
Further improvement of the utility model scheme is in described through hole, to be evenly provided with three spring catch.
The utility model advantage is compared with prior art:
Push rod is connected with spring catch by draw-in groove with tip-lever support, has greatly improved the efficiency of dismounting, reduced labour intensity simultaneously, reduced the manufacturing cost of wheel hub, improved the economic benefit of enterprise.
Accompanying drawing explanation
Fig. 1 is push rod structure schematic diagram.
Fig. 2 is through-hole structure schematic diagram on tip-lever support.
Fig. 3 is the A direction view of Fig. 2.
The specific embodiment
A kind of wheel hub casting machine push rod syndeton as shown in Figure 1, Figure 2, Figure 3 shows, comprise push rod 1 and tip-lever support 2, described push rod 1 lower end edge is circumferentially with draw-in groove 11, and described tip-lever support 2 is provided with through hole 21, in described through hole 21, is provided with the spring catch matching with draw-in groove 11; Described through hole 21 walls are provided with the cavity 23 of closing in, and the plunger 22 of spring catch stretches into through hole 21 inner chambers from the closing in of cavity 23, between the back side of described plunger 22 and cavity 23 walls, are provided with spring 24; In described through hole 21, be evenly provided with three spring catch.
