Description
Technical Field
The utility model relates to machinery and machining center field, in particular to rotatory locking device of machining center main shaft.
Background
With the requirements of aerospace (aluminum alloy and titanium alloy), automobiles, precision molds, heavy industry, 3C alloy or plastic and other representative industries on processing efficiency, processing cost and processing precision, multi-axis linkage machine tools represented by a composite processing center are greatly developed in recent years due to the fact that various working procedures such as turning, milling, drilling, boring and tapping can be completed in single clamping, and the appearance of the composite processing center provides an effective solution for providing the processing precision and efficiency of parts. The combined machining center used in the prior art is formed by combining loading rotary tables of a traditional machining center, and various cutters of the combined machining center share one main shaft. According to different machining conditions, the main shaft needs to be switched to machining states such as turning, milling, boring or drilling at any time. The centering main shaft in the prior art is generally divided into: the synchronous belt transmission device comprises an electric main shaft, a synchronous belt main shaft and a gear transmission main shaft. The main shafts of the processing centers are all provided with: 1. the main shaft can only be used independently and can not be used for multiple purposes; 2. in the prior art, a main shaft and a cutter rotate to process a workpiece, so that the main shaft cannot carry out vertical turning, and cannot replace a turning tool and the like.
Disclosure of Invention
An object of the utility model is to provide a machining center main shaft rotation locking device with main shaft locking hydraulic cylinder.
In order to achieve the above purpose, the technical scheme of the utility model is that:
a rotary locking device for a spindle of a machining center comprises a spindle motor, a transmission shaft, a box body, a spindle, a cutter bar seat positioning block, spindle locking hydraulic cylinders, a spindle coupler, a ram and a motor coupler.
A main shaft locking hydraulic oil cylinder in the device is connected with a hydraulic control unit of a machining center through an oil pipe.
Compared with the prior art, the utility model discloses an actively the effect does:
1. the device can utilize a main shaft locking hydraulic oil cylinder of a machining center to quickly lock and release the main shaft, so that the machining type conversion is realized;
2. after a main shaft locking oil cylinder of the device locks the main shaft, the main shaft and a cutter do not rotate, and a work piece is driven by a workbench to rotate, so that the machining operation of the vertical lathe function of a machining center is realized;
3. the device can quickly replace and process required tools through the tool bar seat, and when the main shaft carries out the conversion of the grinding head and the turning tool, the conversion is quick and the efficiency is high;
4. the device simple structure, convenient operation, greatly reduced the processing cost.
Drawings
Fig. 1 is a schematic structural view of a spindle rotation locking device.
In the figure: 1. the device comprises a spindle motor, 2, a transmission shaft, 3, a box body, 4, a spindle, 5, a cutter bar seat, 6, a cutter bar seat positioning block, 7, a spindle locking hydraulic oil cylinder, 8, a spindle coupler, 9, a ram, 10 and a motor coupler.
Detailed Description
The technical solution of the present invention will be further described clearly and completely with reference to the accompanying drawings.
Referring to the attached figure 1, two main shaft locking hydraulic cylinders 7 are symmetrically arranged at the lower part of a box body 3 of the device, a main shaft 4 is arranged at the middle part in the box body 3, a cutter bar seat positioning block 6 is fixedly arranged at the end part of the main shaft 4, a cutter bar seat 5 is arranged on the cutter bar seat positioning block 6, a main shaft coupler 8 is arranged at the other end of the main shaft 4, the main shaft coupler 8 is connected with a transmission shaft 2, the transmission shaft 2 is arranged on a ram 9, two ends of the ram 9 are respectively connected with a main shaft motor 1 and the box body 3, and a motor coupler 10 is arranged at the other end.
A main shaft locking hydraulic oil cylinder 7 in the device is connected with a hydraulic control unit of a machining center through an oil pipe.
When a common workpiece is processed, a cutter is arranged in a cutter bar seat 5 on a cutter bar seat positioning block 6, a spindle motor 1 drives a motor coupler 10 and a transmission shaft 2 arranged on a ram 9, the transmission shaft 2 drives a spindle 4 to rotate through a spindle coupler 8, the spindle 4 mills, bores, grinds and teeth of the workpiece through the cutter arranged on the cutter bar seat 5, and meanwhile, the cutter for quick replacement processing can be also replaced through the cutter bar seat 5. At this time, the two main shaft locking hydraulic cylinders 7 arranged in the box body 3 are in an out-of-operation state.
When a workpiece needs to be vertically turned, the hydraulic control unit of the machining center drives the two main shaft locking hydraulic cylinders 7 arranged in the middle of the box body 3, the main shafts 4 are locked, so that tools arranged on the main shafts 4 and the tool post seats 5 are not rotated, and meanwhile, the workbench drives the workpiece to rotate, so that machining operation of the vertical turning function of the machining center is realized.
