Description
Technical field
The present invention relates to Clamping Apparatus of Connecting Rod, specifically a kind of connecting rod flexible fixture.
Background technology
We know that connecting rod is one of strength member of transferring power in the engine, and it is arranged between piston and the bent axle, and piston stress is passed to bent axle, change rotatablely moving of bent axle into thereby piston must be moved back and forth.The connecting rod two ends are respectively equipped with crank hole and piston pin hole, add man-hour, will mill both ends of the surface, heavy boring and half right boring concentric reducer hole, bolt hole, mill processing such as microcephaly inclined-plane different connecting rods.Along with improving constantly of automation degree of equipment; The used anchor clamps of connecting rod are the hydraulic pressure frock at present; And flexible relatively poor, all be to carry out particular design and making basically to each product, the anchor clamps investment is very big when causing carrying out the connecting rod trial production of new products and changing product in batches.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art; Provide a kind of rational in infrastructure; Install simply, be convenient for changing, the scope of application is big; Cost is low, is suitable for turnning and milling both ends of the surface, heavy boring and half right boring concentric reducer hole, bolt hole, mills the connecting rod flexible fixture that processing such as microcephaly inclined-plane is used.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of connecting rod flexible fixture; It is provided with a motherboard; Support cylinder and corner clip locking oil cylinder are installed on the motherboard; It is characterized in that: also through bolt two removable daughter boards are installed on the said motherboard, the bloated pin of two point form, the bloated pin of bikini are installed on the every daughter board and support backing plate, connecting rod concentric reducer hole correspondence is installed on bloated pin of bikini and the bloated pin of two point form; Through bloated pin of bikini and the bloated pin of two point form connecting rod concentric reducer hole is positioned; Said support cylinder is positioned at the daughter board bottom, and the corner clip locking oil cylinder is positioned at the daughter board both sides, through the pressing plate on support cylinder and the corner clip locking oil cylinder connecting rod is supported, clamps.
Daughter board according to the invention is provided with and leads to bikini the expand hydraulic oil channel of pin of pin and two point form that expands, and the two point form pin that expands is installed on the daughter board through screw thread with bloated pin of bikini, and is communicated with hydraulic oil channel on the daughter board.The spacing that bikini expands between pin and the bloated pin of two point form can realize adjusting through changing daughter board.
Support backing plate according to the invention supports backing plate and is positioned at connecting rod end face one side through being bolted on the daughter board, through supporting backing plate the connecting rod end face is supported the location.
The present invention is designed to the mother baby plate structure with Clamping Apparatus of Connecting Rod, and the pin that will expand is installed on the daughter board, and support cylinder and corner clip locking oil cylinder are installed on the motherboard, when changing new product, only need change daughter board both can, motherboard and support cylinder, corner clip locking oil cylinder need not replacing.Correspondingly can realize bloated adjustment of selling spacing after changing daughter board, if the aperture is inconsistent, the bloated pin of changing respective aperture gets final product.Against existing technologies, motherboard need not to change when the present invention changed at every turn and produces, only change daughter board both can, strengthened the flexibility of anchor clamps greatly.The present invention is rational in infrastructure, installs simply, is convenient for changing, and operation saving time soon, and production efficiency is high, and safe and reliable, the scope of application is big, has reduced the use cost of anchor clamps.It is applicable to that connecting rod is fixedly clamped, and is used to mill the processing of connecting rod both ends of the surface, heavy boring and half right boring concentric reducer hole, bolt hole, mills working procedure processing such as microcephaly inclined-plane.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further description.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to sketch map.
Label is among the figure: 1. daughter board, and 2. motherboard, 3. the two point form pin that expands 4. supports backing plate, 5. support cylinder, 6. expand pin, 7. corner clip locking oil cylinder of bikini.
The specific embodiment
Can find out from Fig. 1 and Fig. 2, a kind of connecting rod flexible fixture of the present invention, it is provided with a motherboard 2, and support cylinder 5 and corner clip locking oil cylinder 7 are installed on the motherboard 2.General is that support cylinder 5 is installed in corresponding connecting rod bottom, is used for supporting whole connecting rod; Corner clip locking oil cylinder 7 is installed in the connecting rod both sides, is used for clamping connecting rod through the pressing plate on it.Motherboard 2 is provided with the hydraulic oil channel that leads to support cylinder 5 and corner clip locking oil cylinder 7.
Also two removable daughter boards 1 are installed on the motherboard 2 according to the invention through bolt; Two point form the expand pin 6 and support backing plate 4 of pin 3, bikini that expands is installed on the every daughter board 1; Connecting rod concentric reducer hole correspondence is installed on bloated pin 6 of bikini and the bloated pin 3 of two point form, positions through the bloated pin 6 of bikini and 3 pairs of connecting rod concentric reducer holes of the bloated pin of two point form.Two point form pin 3, the bikini pin 6 that expands that expands is commercial part.
