The press with the special structure for automobile rear axle shaft bearings controls in-place situations of feeding and discharging positions and press positions of work pieces by detecting stroke of a cylinder, thereby realizing automation control, increasing action precision and working efficiency, reducing labor intensity, and simultaneously being more reliable in action and reasonable in structure, absolutely meeting severe requirements of work pieces and utilizing output capacity of the oil cylinder to the utmost extent.
Description
Technical field
The utility model relates to a kind of pressing machine, especially relates to a kind of pressing machine that is used for the car rear axle semi-axis bearing.
Background technology
At present, pressing machine is widely used at each production field, generally is used to finish the action of the hole and the interference fit of axle.The pressing machine type have hydraulic pressure, air pressure, more general with hydraulic pressure utilization.The agent structure of general pressing machine is by comprising: motor, oil pump, fuel tank, magnetic valve, check valve, oil cylinder and mechanical framework, motor pump provides power, oil cylinder is by magnetic valve and check valve control, realization press-fits and the action of backhaul, in order to improve the accuracy operability of equipment, and realize its automation, often add pressure regulator valve, the sense switch that puts in place, PLC equal controller to pressing machine.
On structure substantially, oil cylinder generally all is inverted in the top of equipment, can make the downward pressure of oil cylinder reach the maximum that it can be exported like this, determine power unit according to needed pressure size in the concrete reality then, and press-fited workpiece size design mechanical framework.This has just directly caused the different difference of difference, frame for movement of the pressing machine volume size that occurs on the market, make existing pressing machine can not reasonably satisfy different user demands, and the not only heavy mostly volume of existing pressing machine but also bigger, make troubles for installation, transportation, and, can only satisfy press-fiting of very limited specific workpiece because structure is fixed.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of car rear axle semi-axis bearing pressing machine at problems of the prior art, its objective is press-fiting of workpiece on the such major axis of convenient similar car rear axle semi-axis.
The technical solution of the utility model is that this a kind of car rear axle semi-axis bearing comprises workbench and the track that is installed in workbench top with the described pressing machine of pressing machine, track is provided with slide plate, oil cylinder is fixed on the slide plate by the oil cylinder mount pad, positioning sleeve and the brake disc positioning seat and the brake circuit of fixation workpiece also are installed on the slide plate, electric-control system and power unit are installed on the sill of workbench.
Described pneumatic circuit comprises cylinder, magnetic valve and filtering pressure reducing valve, and cylinder, magnetic valve and filtering pressure reducing valve are electrical connection.
Described electric-control system comprises the PLC control module, put in place sense switch and magnetic switch, and PLC control module, put in place sense switch and magnetic switch are electrical connection.
A kind of car rear axle semi-axis bearing with above-mentioned special construction has the following advantages with pressing machine:
1, this kind car rear axle semi-axis bearing situation that puts in place of controlling workpiece upper and lower pieces position and press-fit the position by the stroke that detects cylinder with pressing machine, realize automation control, improved the accuracy of action, also improved operating efficiency, reduced labour intensity, action is more reliable simultaneously.
2, rational in infrastructure, meet the requirement of the harshness of workpiece fully, utilized the fan-out capability of oil cylinder to greatest extent.
3, structure is small and exquisite flexibly, and is reliable and stable, the space availability ratio height.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
In Fig. 1,1: workbench; 2: track; 3: slide plate; 4: oil cylinder; 5: the oil cylinder mount pad; 6: positioning sleeve; 7: the brake disc positioning seat; 8: power unit; 9: cylinder; 10: sense switch puts in place.
The specific embodiment
Figure 1 shows that this kind car rear axle semi-axis bearing pressing machine, this pressing machine comprises workbench 1 and is installed in the track 2 on workbench 1 top, track 2 is provided with slide plate 3, oil cylinder 4 is fixed on the slide plate 3 by oil cylinder mount pad 5, positioning sleeve 6 and the brake disc positioning seat 7 and the brake circuit of fixation workpiece also are installed on the slide plate 3, electric-control system and power unit 8 are installed on the sill of workbench 1, pneumatic circuit comprises cylinder 9, magnetic valve and filtering pressure reducing valve, cylinder 9, magnetic valve and filtering pressure reducing valve are electrical connection, electric-control system comprises the PLC control module, put in place sense switch 10 and magnetic switch, the PLC control module, put in place sense switch 10 and magnetic switch is electrical connection.
The concrete course of work is: with bearing, the lining of bearing, brake disc is enclosed within earlier on the car rear axle semi-axis 11, with pressing machine bearing and lining are pressed into semiaxis interference fit shaft part then, and brake disc is stuck between bearing and the semiaxis axle head, the stroke that the length of semiaxis press-fits much larger than needs, and the brake disc radius is bigger, oil cylinder center and semiaxis, bearing, the lining center is consistent, can make the oil cylinder duty the most reliable the most effective, consideration is fixed bearing and lining with a positioning sleeve 6, semiaxis is headed in bearing and the lining workpiece inaccurate unfavorable factor that puts in place before can having avoided artificially going up part like this and causing press-fiting.
Frame for movement mainly partly is made up of workbench 1, track 2, positioning sleeve 6 and oil cylinder mount pad 5 etc., adopted oil cylinder 4 fixing, slide on the workbench 1 that workpiece is placed and by slide plate 3, solved last part put in place and press-fit between contradiction structurally, and effectively saved the space, this hydraulic system mainly is made up of oil cylinder 4, power unit 8, magnetic valve and check valve etc., for entire work process provides pressure assembling force.
Automatic control process is realized by pneumatic system, the situation that puts in place of controlling workpiece upper and lower pieces position and press-fiting the position by the stroke that detects cylinder, improved operating efficiency, accuracy is higher, move more reliable, pneumatic circuit mainly is made up of cylinder 9, magnetic valve and filtering pressure reducing valve etc., realizes moving workpiece to press-fit part under position and the release action.
Electric-control system is mainly by PLC, form near switch, magnetic switch etc., realizes going up automatically part by the control of PLC system and puts in place, press-fits and press-fit to finish and release these three actions of part down, makes whole course of action harmonious, realizes automation.
Course of action is: go up part → by start button → cylinder workpiece is moved under the oil cylinder → oil cylinder presses down → workpiece is press-fit into place → oil cylinder backhaul → cylinder releases workpiece → following part
This equipment belongs to small-sized press-loading device, and advantage is that volume is little, and is simple in structure, automation control, and the operation simple and convenient, strong for the adaptive capacity in place, and can satisfy press-fiting of similar various longaxones parts.
