Abstract
The utility model discloses a drawplate for the disassembly of the wheels, which comprises a support base, a bracket connected with the support base, a bolt connected with the brace and a lengthening ejector rod connected with the bolt. The drawplate is positioned on the wheels, stressed uniformly while being disassembled and has the advantages of simple structure, simple process, reliability and economy and practicability.
Description
Technical field
The utility model relates to a kind of drawing-die of dismantling wheel.
Background technology
For the dismounting of the parts of shapes such as some pinch rollers, roller, brake hubs, it is under the situations such as special shape such as circular arc, the withdrawal space are narrow and small that certain thickness or wheel limit are especially arranged, the dismounting wheel very difficulty that becomes.
At present, normally used extracting tool is the three-jaw drawing-die, but the hook of three-jaw drawing-die is narrow and small with general wheel fixing point space, is very easy to during operation take off collude, and poor work stability.If use 300mm three-jaw drawing-die, can very easily take off because the space is narrow and small and collude; If use the three-jaw drawing-die of 350mm, thimble screw is long, and the locus is not enough.So adopt original way usually, with crow bar and iron pillow wheel is split out firmly, but operation to be both painstaking like this, operating efficiency is poor again.
Summary of the invention
The purpose of this utility model provides a kind of drawing-die of dismantling wheel, and it is simple in structure, can dismantle wheel directly, easily.
The purpose of this utility model is achieved through the following technical solutions:
A kind of drawing-die of dismantling wheel, it comprises a bracket base, a support that is connected with this bracket base, bolt and and this bolted spreading push rod that is spirally connected with this support.
Wherein, this bracket base is a U-shaped plate.
Wherein, this support comprise two with the vertically disposed side plate of this bracket base and a panel that be arranged in parallel with this bracket base, these two blocks of side plates are connected with this bracket base, two blocks of side plates of this panel and this are connected.
Wherein, this spreading push rod is an elongated cylinder, and the one end is provided with the thimble head, and the other end is provided with a blind hole, and this thimble head is that tapering is the cone of 60 degree.
Wherein, this bolt end is provided with a projection, and this projection is contained in the blind hole of this spreading push rod.
Positive progressive effect of the present utility model is: the drawing-die of dismounting wheel comprises a bracket base, a support that is connected with this bracket base and a bolt that is spirally connected with this support, it directly is placed on the wheel, drawing-die is stressed evenly during the dismounting wheel, has advantages such as it is simple in structure, simple for production, use is firm, economical and practical.

The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As Fig. 1-shown in Figure 4, a kind of drawing-die of dismantling wheel, it comprises the bracket base 1 of a U-shaped plate, support that is connected with this bracket base 12, a bolt 3 and a spreading push rod 4 that is connected with this bolt 3 that is spirally connected with this support 2.
This support 2 comprise two with this bracket base 1 vertically disposed side plate 21 and a panel 22 that be arranged in parallel with this bracket base 1, these two blocks of side plates 21 are connected with this bracket base 1, two blocks of side plates 21 of this panel 22 and this are connected, and the thickness of this panel 22 is greater than the thickness of the bracket base 1 of two blocks of side plates 21 and U-shaped plate.
This spreading push rod 4 is elongated cylinders, and the one end is provided with thimble head 41, and the other end is provided with a blind hole 42, and wherein, thimble head 41 is that tapering is the cone of 60 degree.
This bolt 3 is arranged on this panel 22 centers, and these bolt 3 ends are provided with a projection 31, this projection 31 is contained in the blind hole 42 of this spreading push rod 4, the axis of this bolt 3 is by the U-shaped center of this bracket base 1, exert pressure to power transmission shaft and drawing-die by the bolt 3 and the spreading push rod 4 that are combined together like this, make drawing-die stressed evenly.
During concrete drawing-die of using this dismounting wheel, the axle of generally desiring to be disassembled, hole be interference fits normally, as shown in Figure 5, at first, drawing-die is placed on the wheel 5, the U-shaped of the bracket base 1 of drawing-die partly is stuck on the power transmission shaft 6, the whole face of bracket base 1 is close to below the wheel 5 simultaneously;
Then, directly use the bolt 3 of drawing-die to cooperate spreading push rod 4, thimble head 41 is aligned power transmission shaft 6 centers position (, being used for limiting, determining the position of thimble head) in advance in the default hole of center transmission shaft, evenly stressed when making drawing-die work;
At last, by screwing bolt 3 to power transmission shaft 6 exert pressure (the left direction of arrow), the reaction force (the right direction of arrow) that is created on the bracket base 1 is released wheel 5, realize getting loose of wheel 5 and power transmission shaft 6, and when power transmission shaft 6 unloads, spreading push rod 4 breaks away from bolt 3 simultaneously, avoids bolt 3 impaired.
As shown in Figure 6, laborsaving when desiring to be disassembled under other situations such as axle, hole interference fits be tight slightly in order to dismantle, can be directly in drawing-die one of the adapted mechanic jacks 7 of tonnage according to actual needs.
The appearance and size of the wheel that this drawing-die can be dismantled as required is different and carry out size design, realizes the dismounting wheel to cooperate.
