Abstract
The spoke processing equipment with a geometric center coinciding with a rotary center, which belongs to the technical field of mechanical manufacture, and mainly comprises a chuck and a machine tool spindle box, wherein a horizontal displacement worktable is arranged below the chuck and is connected with a displacement motor; and a rotary worktable is arranged on the horizontal displacement worktable and is connected with the bottom of the chuck and a rotary motor, and a non-contact displacement sensor is arranged at the side upper part of the chuck. When at work, the spoke horizontally rotates 360 degrees, and the displacement sensor carries out the detection of multi-point bounce for the cylindrical contour line of the spoke so as to obtain the included angle between the geometric center and the coordinate X axis and the distance between the geometric center and the processing center; the rotary table enables the spoke to rotate, so that the geometric center coincides with the X-axis, and the horizontal displacement worktable enables the geometric center to coincide with the processing center; and a single or a plurality of wheel bolt holes are processed by the spindle box. The utility model effectively solves the periodic bounce problem caused by the deviation of the actual center of the spoke.
Description
Technical field:
The utility model belongs to machinery manufacturing technology field, is a kind of vehicle spoke process equipment.
Background technology:
Existing spoke process equipment mainly is made of chuck and lathe headstock, processing method is that chuck positions by the fabrication hole in the middle of the spoke, clamp, main spindle box processes the construction bolt hole on the spoke, because being a plurality of bolts, the fixed form between wheel and the wheel is fixed together by bolt hole on the spoke and axletree end, so whether the position of bolt hole is precisely very crucial, because in the spoke manufacture process, make geometric center (spoke excircle configuration practical center) and its centre of gyration (convenience center of bolt hole, theoretic center) all can there be to a certain degree deviation, comprises circular runout deviation and axial runout deviation).When wheel rotated, the geometric center that has a manufacture deviation can form in motion process around its centre of gyration periodically beated, and caused problems such as vibration, the tire wear of car load be inhomogeneous.
Summary of the invention:
The purpose of this utility model is the spoke process equipment that will provide a kind of geometric center to overlap with the centre of gyration.
The scheme of the utility model technical solution problem is installed the horizontal displacement workbench below chuck, the horizontal displacement workbench is connected with displacement motor, on the horizontal displacement workbench rotary table is housed, rotary table is connected with the bottom of chuck, rotary table is connected with turning motor, above the side of chuck non-contact displacement transducer is arranged.Horizontal displacement workbench and rotary table constitute polar coordinates displacement slide unit.During work, turning motor drives rotary table makes spoke horizontally rotate 360 degree, displacement transducer carries out the multiple spot glitch detection to spoke excircle configuration line, after detecting data machine being handled as calculated, obtain actual deviation between spoke geometric center and the machining center, draw between geometric center and the coordinate X-axis distance between the angle and geometric center and machining center, start turning motor drive rotary table and make the spoke rotation, geometric center is overlapped with X-axis, restart displacement motor drive horizontal displacement workbench the spoke geometric center is overlapped with machining center, main spindle box is processed single or multiple wheel bolts hole.
In order further to improve automaticity and accuracy, displacement transducer is connected with controller, and controller connects displacement motor and turning motor respectively.Its middle controller is the controller that comprises the Computer Processing function.After displacement transducer tested out the spoke data, controller calculated test initial point and machining center position, and control displacement motor and turning motor work, and the test initial point is overlapped with machining center.
The brief introduction of operation process;
1) clamping wheel;
Automatic or manual is loaded onto wheel to be processed or spoke, presses the automatic clamping wheel of start button air spider.
2) test wheel;
Displacement transducer carries out the circular runout detection by predefined relevant position parameter to wheel or spoke.The computer acquisition relevant test data.
3) computer data is handled;
The a computer is handled the relevant test data of gathering, and determines the manufacturing geometric center and the machining center position actual deviation of the spoke outer contour of wheel.
The b computer confirms whether the manufacturing geometric center overlaps back wheel or spoke to be processed with machining center qualified.Qualified sending instructs next work step of execution, defective sending automatically to take off defective spoke signal, and the operator takes off defective workpiece.
4) move the manufacturing geometric center;
Polar coordinates displacement slide unit moves on to assigned position by the given corner of computer, displacement with the manufacturing geometric center of wheel.Geometric center is overlapped with machining center (centre of gyration).
5) processing spoke bolt hole;
After two centers overlap.Polar coordinates displacement slide unit auto lock.Main spindle box by F.F., worker advance, the working method of rewind down processes single or multiple spoke bolts hole.Single in this way bolt hole machining spindle can be processed a plurality of wheel mounting bolts hole by the method for machine tool rotary working table angle transposition.The multi-processing main shaft can once be finished a plurality of bolt hole processing.
6) polar coordinates displacement slide unit returns the demarcation original position;
After wheel or spoke construction bolt hole machine, take off wheel.Lathe unclamps polar coordinates displacement slide unit forced locking device automatically, and slide unit returns the demarcation original position automatically.
7) lathe expanded function;
Lathe can also double as wheel run-out tolerance testing equipment use after increasing the part annex.
This process and apparatus can only reduce the circular runout deviation in wheel or the spoke process.Make wheel or spoke quality can obtain in various degree raising.
The utility model has solved effectively because the problem of periodically beating that deviation causes appears in the spoke practical center, and is simple to operate, dependable performance.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is that spoke geometric center and centre of gyration deviation are adjusted schematic diagram.
The specific embodiment:
The utility model is made of chuck 1 and main spindle box 2, spoke 3 is fixed on the chuck 1, horizontal displacement workbench 4 is installed below chuck 1, horizontal displacement workbench 4 is connected with displacement motor 5, rotary table 6 is housed on the horizontal displacement workbench 4, rotary table 6 is connected with the bottom of chuck 1, rotary table 6 is connected with turning motor 7, non-contact displacement transducer 8 is arranged above the side of chuck 1, displacement transducer 8 is connected with controller 9, and controller 9 connects displacement motor 5 and turning motor 7 respectively.Wherein, displacement transducer 8 adopts the laser testing instrument, and displacement motor 5 and turning motor 7 adopt servomotor.
