Abstract
The utility model discloses a kind of drum brake brake shoe iron processing tool, comprise frock base plate, described frock base plate is provided with four oil cylinder fixing bases, upper end at four oil cylinder fixing bases is separately installed with hydraulic jack, on the piston rod of hydraulic jack, be separately installed with pressing plate, it is evenly distributed that four oil cylinder fixing bases are circumferencial direction.During work, brake shoe iron to be processed is placed in frock, with brake shoe iron end face, a pin-and-hole and roller axis hole location, then press starting switch, by being fixed on the pressing plate hydraulic compression brake shoe iron for hydraulic jack on oil cylinder fixing base, the oil duct that in oil cylinder fixing base, processing communicates with hydraulic jack, bottom is fixed on frock base plate.Brake shoe iron just can start just can start the processing of cutting of this operation after press-fiting well.Due to manufactured pin-and-hole of brake shoe iron and roller pin hole precision higher, the improvement of tool locating mode can guarantee size and the Geometrical Tolerance Principle after the processing of this operation of brake shoe iron.
Description
Technical field
The utility model relates to a kind of processing tool of drum brake parts, relates in particular to the processing tool that a kind of drum brake brake shoe iron cuts, and belongs to machinery manufacturing technology field.
Background technology
In order to strengthen drum brake assembly output, further reduce brake shoe iron production cost, enhance productivity in the recent period, my company has purchased brake shoe iron and has cut with one of GZ5130D computerized numerical control sawing machine, for replacing the milling of brake shoe iron on milling machine to open processing.The process of this operation is: brake shoe iron to be processed is installed to processing excircles, end face and location, extension spring hole and is fixed in frock, after clamping, process by hydraulic jack with pressing plate.The shortcoming of this locate mode is: because manufactured brake shoe iron excircle dimension is all larger with extension spring hole endoporus dimensional tolerance, when frock is located with this, positioning precision is lower, exists and compared with large positioning gap, is difficult to guarantee the processing machined surface that brake shoe iron cuts afterwards and size and the Geometrical Tolerance Principle at brake shoe iron center.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of machined surface and the size at brake shoe iron center and drum brake brake shoe iron processing tool of Geometrical Tolerance Principle that rear brake shoe iron cuts that can guarantee by the improvement of tool locating mode to process.
In order to address the above problem, the utility model by the following technical solutions:
A kind of drum brake brake shoe iron processing tool, comprise frock base plate, described frock base plate is provided with four oil cylinder fixing bases, upper end at four oil cylinder fixing bases is separately installed with hydraulic jack, on the piston rod of hydraulic jack, be separately installed with pressing plate, it is evenly distributed that four oil cylinder fixing bases are circumferencial direction.
Below the further optimization of the utility model to such scheme:
Described frock base plate is " work " font structure.
Further optimize: on frock base plate near wherein one end bilateral symmetry of its position of center line be provided with brake shoe iron on a pin-and-hole prop up one to one pin-and-hole alignment pin, the bilateral symmetry of the other end be provided with brake shoe iron on roller axis hole roller axis hole alignment pin one to one.
During work, brake shoe iron to be processed is placed in frock, with brake shoe iron end face, a pin-and-hole and roller axis hole location, then press starting switch, by being fixed on the pressing plate hydraulic compression brake shoe iron for hydraulic jack on oil cylinder fixing base, the oil duct that in oil cylinder fixing base, processing communicates with hydraulic jack, bottom is fixed on frock base plate.Brake shoe iron just can start just can start the processing of cutting of this operation after press-fiting well.Due to manufactured pin-and-hole of brake shoe iron and roller pin hole precision higher, the improvement of tool locating mode can guarantee size and the Geometrical Tolerance Principle after the processing of this operation of brake shoe iron.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of processing tool in the utility model embodiment;
Accompanying drawing 2 is the top view of accompanying drawing 1.
In figure: 1-brake shoe iron; 2-pressing plate; 3-hydraulic jack; 4-oil cylinder fixing base; 5-props up pin-and-hole alignment pin; 6-frock base plate; 7-roller axis hole alignment pin; 8-center line.
The specific embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of drum brake brake shoe iron processing tool, comprise frock base plate 6, described frock base plate 6 is provided with four oil cylinder fixing bases 4, in the upper end of four oil cylinder fixing bases 4, be separately installed with hydraulic jack 3, on the piston rod of hydraulic jack 3, being separately installed with 2, four oil cylinder fixing bases 4 of pressing plate, to be circumferencial direction evenly distributed.
Described frock base plate 6 is " work " font structure, on frock base plate 6 near wherein one end bilateral symmetry of its center line 8 positions be provided with brake shoe iron 1 on a pin-and-hole prop up one to one pin-and-hole alignment pin 5, the bilateral symmetry of the other end be provided with brake shoe iron 1 on roller axis hole roller axis hole alignment pin 7 one to one.
During work, brake shoe iron 1 to be processed is placed in frock, with brake shoe iron 1 end face, a pin-and-hole and roller axis hole location, then press starting switch, by being fixed on the hydraulic jack 3 use pressing plate 2 hydraulic compression brake shoe irons 1 on oil cylinder fixing base 4, the oil duct that the interior processing of oil cylinder fixing base 4 communicates with hydraulic jack 4, bottom is fixed on frock base plate 6.Brake shoe iron 1 just can start just can start the processing of cutting of this operation after press-fiting well.
