Description
Technical field
This utility model relates to the assembly tooling of bearing, is specifically related to a kind of assembly tooling loading bearing in wheel-class parts.
Background technology
In industrial processes, usually can run into the situation loading bearing in wheel-class parts. Such as, harvesting machinery has substantial amounts of regulating wheel, it is necessary in regulating wheel, load bearing or axle sleeve. Traditional assembling mode, need to be placed on installed position by bearing, knocks bearing upper surface with hammer or hammer, bearing is pressed into corresponding position. Owing to being localized contact between hammer and hammer and bearing, unbalance stress, it is easy to the situation that bearing tilts occurs. This mode not only assembly precision not easily ensures, and the labor intensity of workman is high.
Along with the development of technology, commercial production occurring in that, hot charge practice and cold charge install the technology of bearing. Cold charge is to put in low temperature environment by bearing, for instance put into by bearing in low temperature liquid nitrogen, and bearing is subject to cold events, is then loaded in regulating wheel again. Hot charge practice is first regulating wheel to be heated, for instance heats regulating wheel, regulating wheel expanded by heating by high temperature spray gun, is then placed in bearing, and after cooling, regulating wheel shrinks, and completes assembling. Although what both approaches was relatively primitive knocks installation, making progress property, but all there is cost problem high, inefficient.
Summary of the invention
The purpose of this utility model is to provide a kind of assembly tooling loading bearing in wheel-class parts quickly loading in wheel-class parts by bearing.
In order to realize object above, the technical scheme of the assembly tooling that this utility model loads bearing in wheel-class parts is as follows: load the assembly tooling of bearing in wheel-class parts, including workbench, load maintainer, load maintainer includes the pressure head for applying axial load to the bearing face of bearing to be assembled, pressure head has the top pressure surface with the press-fit of bearing face top, workbench is provided with for the axially-movable of the bearing mounting hole at wheel-class parts of bearing is carried out spacing position limiting structure, described position limiting structure has the supporting surface of the corresponding site for supporting described wheel-class parts.
Described pressure head is arranged with described position limiting structure above-below direction.
Described position limiting structure is the spacing preiection being located on workbench, and described supporting surface is formed by the upper surface of described spacing preiection.
The axis coaxle line of the axis of described spacing preiection and pressure head.
Described pressure head is ladder shaft-like, and pressure head includes big footpath section and path section, and described top pressure surface is formed by the step surface between big footpath section and path section.
Described load maintainer includes hydraulic cylinder, and described pressure head is connected to the piston rod end of hydraulic cylinder, and workbench is provided with bracing frame, and the cylinder body of described hydraulic cylinder is connected on bracing frame.
Support frame as described above is additionally provided with reversal valve and the reversing valve operated lifting handle carrying out commutating, is connected by conduit under fluid pressure between described reversal valve and hydraulic cylinder.
The beneficial effects of the utility model: this utility model assembly tooling is when in use, utilize position limiting structure that wheel-class parts is supported, after bearing is placed on the correct position of wheel-class parts, pressure head presses to bearing under the effect of load maintainer, is pressed in the bearing mounting hole of wheel-class parts by bearing. Under the position-limiting action of position limiting structure, it is ensured that bearing is in the tram in wheel-class parts, it is prevented that excessive movement when bearing loads. By this assembly tooling, it is possible to quickly complete the assembling of bearing, relative hammering method installs the mode of bearing, and installation accuracy is high, and alleviates the labor intensity of workman. Relative to cold charge or hot charging, this assembly tooling is simple to operate, and efficiency is high, and does not use liquid nitrogen etc., advantage of lower cost.

Detailed description of the invention
The embodiment of a kind of assembly tooling loading bearing in wheel-class parts of this utility model: as shown in Figure 1-2, the assembly tooling of bearing is loaded in wheel-class parts, including workbench 1, load maintainer, load maintainer includes the pressure head 5 for applying axial load to the bearing face of bearing to be assembled, pressure head 5 has the top pressure surface 51 with the press-fit of bearing face top, workbench 1 is provided with for the axially-movable of the bearing mounting hole at wheel-class parts of bearing is carried out spacing position limiting structure, and position limiting structure has the supporting surface of the corresponding site for supporting wheel-class parts. In the present embodiment, for regulating wheel as wheel-class parts.
Load maintainer also includes hydraulic cylinder 6, hydraulic gear pump 10, hydraulic oil container 11, and the hydraulic oil in hydraulic oil container is converted into hydraulic oil by hydraulic gear pump 10, is transported in hydraulic cylinder 6. Hydraulic oil container 11 is positioned at the lower section of workbench 1, and hydraulic gear pump 10 is positioned at the top of hydraulic oil container 11. Workbench 1 is provided with bracing frame 7, and the cylinder body of hydraulic cylinder 6 is connected on bracing frame, and hydraulic cylinder above-below direction is installed. Bracing frame is additionally provided with reversal valve 8 and the reversing valve operated lifting handle 9 carrying out commutating, is connected by conduit under fluid pressure between reversal valve 8 with hydraulic cylinder 6.
Pressure head 5 is connected to the piston rod end of hydraulic cylinder, and pressure head 5 is arranged with position limiting structure above-below direction. Position limiting structure is the spacing preiection 2 being located on workbench, and supporting surface is formed by the upper surface of spacing preiection 2. Spacing preiection 2 is cylindric, the axis coaxle line of the axis of spacing preiection 2 and pressure head 5. Pressure head 5 is in ladder shaft-like, and pressure head 5 includes big footpath section and path section 52, and top pressure surface 51 is formed by the step surface between big footpath section and path section 52.
In specifically used, being placed on the upper surface of spacing preiection 2 by regulating wheel 3, the bearing mounting hole of regulating wheel 3 is exactly in the top of positive stop lug boss 2, when placing, makes the installing hole axis of regulating wheel 3 be generally on the axis of positive stop lug boss 2.Again bearing to be assembled is put 4 in the position of bearing mounting hole, then operation lifting handle 9, under the driving of hydraulic cylinder 6, pressure head 5 moves downward, the path section 52 of the lower end of pressure head is first in dead eye, after the bearing face of top pressure surface 51 contact bearing 4 of pressure head 5, start last item and hold 4, make bearing 4 load gradually in the bearing mounting hole of regulating wheel 3. Due to the position-limiting action of spacing preiection 2, the moving downward stroke and can be restricted of bearing 4, it is prevented that bearing is installed excessive, it is ensured that bearing is in correct installation site. After installation, by reverse operating lifting handle 9, make pressure head 5 increase, regulating wheel can be taken off.
In the present embodiment, stair-stepping by pressure head is arranged to so that its path section plays guide effect, it is possible to mobile regulating wheel enables the path section of pressure head to enter in dead eye. In other embodiments, pressure head also can be not provided with stepped, but cylinder.
