The utility model solves the problems by the following technical means:
the utility model provides an eccentric wheel machining clamp which comprises a device base, a clamp assembly and a workbench assembly, wherein the clamp assembly and the workbench assembly are arranged on the device base, the workbench assembly comprises a workbench and a driving mechanism for driving the workbench to move, and a positioning pin is arranged on the workbench.
Further, be provided with on the equipment base with workstation sliding fit's workstation base, actuating mechanism includes lead screw and drive lead screw pivoted motor, the lead screw passes the workstation and with workstation threaded connection.
Further, a motor mounting seat is arranged on the equipment base, and the motor is mounted on the motor mounting seat.
Further, a balancing weight is arranged on the equipment base.
Further, the clamp assembly includes a clamp base and a clamp head.
Further, the motor is a servo motor.
The utility model has the beneficial effects that:
the eccentric wheel machining clamp comprises an equipment base, a clamp assembly and a workbench assembly, wherein the clamp assembly and the workbench assembly are arranged on the equipment base, the workbench assembly comprises a workbench and a driving mechanism for driving the workbench to move, and a positioning pin is arranged on the workbench. The eccentric wheel processing clamp disclosed by the utility model can meet the processing requirements of eccentric wheels with different eccentricities, and saves the production cost.
Drawings
The utility model is further described below with reference to the drawings and examples.
FIG. 1 is a schematic perspective view of a preferred embodiment of the present utility model;
fig. 2 is a top view of a preferred embodiment of the present utility model.
Detailed Description
The utility model is further described in detail below by means of the figures and examples. The features and advantages of the present utility model will become more apparent from the description. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model.
In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.
Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
As shown in fig. 1 to 2, the present embodiment discloses an eccentric wheel machining fixture, which comprises a device base 1, and a fixture assembly and a workbench assembly which are installed on the device base, wherein the fixture assembly comprises a fixture base 2 and a chuck 3, and the chuck is driven to move on the fixture base through a driving piece so as to clamp or unclamp an eccentric wheel workpiece; the workbench assembly comprises a workbench 9 and a driving mechanism for driving the workbench to move, in the embodiment, a workbench base 10 which is in sliding fit with the workbench is arranged on the equipment base, the driving mechanism comprises a screw rod 6 and a motor 5 for driving the screw rod to rotate, the screw rod penetrates through the workbench and is in threaded connection with the workbench, a motor mounting seat 4 is arranged on the equipment base, the motor is mounted on the motor mounting seat, and the motor is a servo motor. When the eccentric wheel is in operation, the motor drives the screw rod to reciprocate, and the workbench can be pushed to reciprocate along the workbench base, so that the position of the workbench is adjusted, the workbench can move according to the eccentricities of different eccentric wheels, and the moving distance is directly set according to the eccentricities of the eccentric wheels to be processed; the datum point of the workbench is arranged at the rotation center of the processing equipment. The workbench is provided with a locating pin 8 which is used for processing and locating the eccentric wheel 7.
In this embodiment, anchor clamps base and workstation base are wedge, effectively guarantee the precision.
In this embodiment, be provided with balancing weight 11 on the equipment base, the weight of balancing weight equals the sum of motor mount pad and motor weight, and the distance of the two mass points of balancing weight mass point and motor mount pad, motor to equipment center of rotation equals to guarantee that the moment size equals.
The specific implementation steps are as follows: 1. the clamp is in a loosening state; 2. setting the offset distance of the workbench according to the eccentricity; 3. mounting an eccentric wheel workpiece to be processed on a workbench through a locating pin; 4. the chuck clamps the eccentric wheel workpiece to be processed; 5. starting the equipment for processing; 6. stopping the processing ending equipment; 7. loosening the clamp; 8. and taking down the eccentric wheel workpiece and feeding again.
In summary, the eccentric wheel processing clamp disclosed by the utility model can directly set the offset distance of the workbench according to the magnitude of the eccentric distance through program control, and is high in applicability for processing eccentric wheels with different eccentric distances; when the eccentricity of the eccentric wheel to be machined is changed, the fixture is not required to be manually disassembled and assembled, the machining efficiency is high, and the machining precision of the workpiece is high.
