Abstract
The utility model relates to a pull rod component of a ball high-speed mechanical main shaft, and particularly relates to a pull rod mechanism which provides a broaching force for a broaching component of the main shaft and can clean the inside of the main shaft through entering air flow. According to the pull rod component, a pull rod ejector sleeve (1) is fixed at the tail end of a pull rod main body (4); a big sealing ring (2) is arranged between the outer wall of the pull rod ejector sleeve (1) and the inner cavity wall of the pull rod main body (4); a disk spring (5) and a disk spring gland (6) are fixed on both the middle part and the lower part of the pull rod main body (4); a connecting rod (7) is sleeved on the head part of the pull rod main body (4); and at least one circle of small sealing ring (8) is fixed on the outer wall of the connecting rod (7). The pull rod component can ensure the rotation accuracy of a core shaft, reduce the vibration of the entire mechanism, is more suitable for adjusting a rotating main shaft, and can improve the control accuracy of the broaching force.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind of pull bar and building block thereof of broach force being provided for the main spindle broach assembly.
Background technology
At existing main shaft pull bar, the fitness of itself and rotating shaft is not high, so cause the entire mechanism vibrations through regular meeting, hinders main shaft can not improve rotating speed even cisco unity malfunction, and in addition, broach force control is inaccurate, makes the cutter loading and unloading go wrong easily.
Summary of the invention
The utility model relates to a kind of rod assembly of ball high speed machine main shaft, and it has solved deficiency of the prior art.
The utility model technical solution is on pull bar main body (4) basis of existing afterbody band screw plug (3); The utility model particularly tail end of pull bar main body (4) is fixed with pull bar top cover (1), is provided with large sealing packing ring (2) between the outer wall of pull bar top cover (1) and the internal chamber wall of pull bar main body (4); Pull bar main body (4) middle part and bottom all are fixed with disk spring (5) and dish spring gland (6), and pull bar main body (4) head is with connecting rod (7), and connecting rod (7) outer wall is fixed with at least one ring small sealing ring (8).
The pull bar main body afterbody of the utility model can slide in the cover of pull bar top, and disk spring, dish spring gland can slide on pull bar, during work; Pull bar top cover and dish spring gland are fixed, and the pull bar main body moves downward under external force, and this moment, disk spring received force compresses; Produce elastic force and act on the pull bar main body; Connecting rod is connected with tool-broaching mechanism, and after external force was cancelled, the pull bar main body then produced pulling force upwards.
The advantage of the utility model is:
1, the quality of fit of pull bar top cover and pull bar and mandrel is higher, thereby can guarantee the mandrel running accuracy, reduces the vibrations of entire mechanism, is more suitable for adjusting rotary main shaft and uses;
2, the position of connecting rod restriction dish spring gland can make this mechanism before installing, meet the requirements of size and produce certain pretightning force;
3, the thickness of adjustment dish spring gland can be adjusted pretightning force, makes it the broach force of the demand that reaches, and improves the control accuracy of broach force.
4, through the centre bore and the connecting rod of pull bar main body, can the drifting dust source of the gas be provided to tool-broaching mechanism.
