As shown in fig. 1 to 3, the system for online detection and automatic tool compensation in a production line comprises a worktable 1, a manually adjustable tightening device 2, a hydraulic tailstock thimble 3, a supporting device 4 and an outer diameter measuring device 5, wherein the manually adjustable tightening device 2 is disposed on the left side of the worktable 1, the hydraulic tailstock thimble 3 is disposed on the right side of the worktable 1, the manually adjustable tightening device 2 comprises a manual tailstock thimble 21, the manual tailstock thimble 21 is slidably connected with the worktable 1, the supporting device 4 is disposed on the worktable 1 and located between the manually adjustable tightening device 2 and the hydraulic tailstock thimble 3 for supporting a rotor, so that the rotor shaft is adjusted to be coaxial with the manual tailstock thimble 21 and the hydraulic tailstock thimble 3, the worktable 1 is provided with a plurality of outer diameter measuring devices 5 for detecting the outer diameter of the processed rotor shaft and feeding back the outer diameter data to a background computer, and the background computer compares the outer diameter data with the tolerance range, so that the cutter is controlled to realize automatic compensation, and the outer diameter of the workpiece to be machined is ensured to meet the standard.
In this embodiment, the outer diameter measuring device 5 includes a hydraulic cylinder 51 and an outer diameter measuring instrument 52, the hydraulic cylinder 51 is fixedly connected to the worktable 1, and an output shaft thereof is fixedly connected to a housing of the outer diameter measuring instrument 52.
In this embodiment, a guide rail 23 is arranged on the workbench 1, the manual tailstock thimble 21 is fixedly connected to the bottom plate 22, the bottom plate 22 is slidably connected to the workbench 1 through the guide rail 23, and positioning holes 24 for adjustment are arranged on the workbench 1 and the bottom plate 22. The positioning hole 24 is used for adjusting the position of the manual tailstock ejector pin 21, so that the manual tailstock ejector pin is suitable for rotor shafts with different lengths.
In this embodiment, the supporting device 4 includes a supporting block 41 and a lifting hydraulic cylinder 42, a sliding rod 43 is fixedly connected to the bottom of the supporting block 41, the sliding rod 43 is slidably connected to the workbench 1, the supporting block 41 is further fixedly connected to an output shaft of the lifting hydraulic cylinder 42, and the lifting hydraulic cylinder 42 is fixedly connected to the workbench 1.
The working process and the principle thereof are as follows:
after the product is processed, the product to be measured is placed on the support block 41 by an automatic device such as a mechanical arm or a manual work, the output shaft of the lifting hydraulic cylinder 42 is extended to drive the support block 41 to ascend, the rotor reaches the height which is fixedly positioned with the hydraulic tailstock ejector pin 3 and the manual tailstock ejector pin 21, the extension length of the manual tailstock ejector pin 21 is adjusted in advance according to the principle that the position to be measured of the rotor shaft is aligned with the outer diameter measuring instrument 52, and when the rotor reaches the preset height, the hydraulic tailstock ejector pin 3 is extended to fix the rotor shaft.
And then the hydraulic oil cylinder 51 drives the outer diameter measuring instrument 52 to move towards the position of the rotor shaft, when the outer diameter measuring instrument 52 reaches a measuring position, the measuring rods 521 on the outer diameter measuring instrument 52 move towards the middle until the two measuring rods 521 contact the rotor shaft, the outer diameter of the product is measured through the opening and closing degree of the measuring rods 521, the measured data is transmitted to a background computer for analyzing data, and then the result is output by the background computer, so that the starting of a tool compensation system in the machine tool machining is controlled. The outer diameter measuring instrument 52 is a conventional instrument for measuring an outer diameter.
The output result flow is as follows:
and if the outer diameter is qualified, judging whether compensation is needed, starting a compensation program when the next rotor is processed if the compensation is needed, and if the compensation is not needed, continuously processing according to the original processing program, wherein the processed product enters a product qualified area.
If the outer diameter is unqualified, the outer diameter is judged to be over-tolerance or under-tolerance, the over-tolerance indicates that the outer diameter of the product is too large, the product is taken out and placed in a reprocessing area, production is stopped, and the machine tool is modulated, and if the under-tolerance indicates that the outer diameter is too small, the rotor cannot be converted into a qualified product through reprocessing, so the rotor is taken out and placed in a waste area, production is stopped similarly, and the machine tool is modulated.
The following is illustrated with reference to specific examples:
assuming a product tolerance of +0 to +20 μ, the pass size is set to +5 μ to +15 μ, 0 to +5 μ is set to the lower offset size, +15 μ to +20 μ is set to the upper offset size, the negative tolerance heel larger than 20 μ is set to the lower overshoot and the upper overshoot, and the offset size is set to 5 μ.
When the detected size is in the range of +5 mu to +15 mu, the machine tool does not start the compensation program when processing the next workpiece;
when the detected size is in the range of +15 mu to +20 mu, the machine tool starts a compensation program when processing the next workpiece; increasing the processing size by 5 mu on the original basis;
when the detected size is in the range of 0 mu to +5 mu, the machine tool starts a compensation program when processing the next workpiece, and reduces the processing size by 5 mu on the original basis, so that the positive processing size can be maintained in the tolerance range of +5 mu to +15 mu.
When the detected size exceeds +20 mu, the production is stopped, and the machine tool is modulated to obtain an ultra-poor product which can be processed and adjusted.
When the detected size is smaller than 0 mu, the production is stopped, and the machining adjustment can not be carried out on the ultra-poor product under the condition of modulating the machine tool.
Based on the above: after the processing is finished, the attachments on the surface of the product to be detected are flushed and cleaned, and then the detection is carried out, so that the influence of the processing scraps of the cutting fluid box on the detection result during the real-time detection is avoided, and the obtained size data result is more accurate; the calculated compensation value is more accurate, so that the size precision of the product is improved, and the yield of the product is better guaranteed.
It will be appreciated by those skilled in the art that the utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the utility model are intended to be embraced therein.
