Detailed description of the invention
The explanation of following embodiment is with reference to accompanying drawing, can be in order to the specific embodiment implemented in order to example this utility model.Direction that this utility model is previously mentioned and position term, such as " on ", D score, "front", "rear", "left", "right", " interior ", " outward ", " top ", " bottom ", " side " etc., be only the direction with reference to accompanying drawing or position.Therefore, the direction of use and position term are to illustrate and understand this utility model, rather than the restriction to this utility model protection domain.
Refer to shown in Fig. 1, this utility model embodiment provides a kind of nuclear plant pressure vessels kingbolt to measure system, including: industrial computer 1, programmable logic controller (PLC) 2, machine tool motion control system 3 and measurement apparatus 4, wherein, measurement apparatus 4 is for contacting with tested kingbolt under the control of machine tool motion control system 3, produce activation signal and be sent to industrial computer 1 and programmable logic controller (PLC) 2, industrial computer 1 and programmable logic controller (PLC) 2 are for processing this activation signal, and obtain the relative coordinate values of measurement apparatus 4 and tested kingbolt contact point.
Refer to shown in Fig. 2, in the present embodiment, measurement apparatus 4 farther includes again:
At least chaining pin 41, for contacting with tested kingbolt；
Gauge head 42, the mechanical lever power produced for being contacted with tested kingbolt by chaining pin 41 is converted into low tension signal；
Centre mount 43, is used for installing chaining pin 41；
Lathe connection handle 44, for connecting machine tool kinetic control system.
Additionally, measurement apparatus 4 also includes chaining pin extension rod 45, lay respectively between gauge head 42 and centre mount 43, between gauge head 42 and lathe connection handle 44.
Specifically, in the present embodiment, chaining pin 41 totally 5, wherein 4 is horizontally disposed, and is mutually perpendicular to, and can be described as horizontal chaining pin, and another root is longitudinally disposed, and perpendicular with horizontal chaining pin, can be described as longitudinal chaining pin.Thus, centre mount 43 is five to centre mount, to install 5 chaining pins 41.
Chaining pin 41 is the data terminal of measurement apparatus 4, it is connected with machine tool motion control system main shaft by connectors such as centre mount 43, gauge head 42, chaining pin extension rod 45, lathe connection handles 44, contact with tested kingbolt under the drive of machine tool motion control system (the XYZ axle of lathe), produce activation signal (mechanical lever power), after carrying out data conversion by gauge head 42, it is sent to industrial computer 1 and programmable logic controller (PLC) 2 processes.Signal transmission between chaining pin 41 and gauge head 42 uses infrared transmission.
Below in conjunction with Fig. 3-Fig. 8, operation principle and the work process of the present embodiment nuclear plant pressure vessels kingbolt measurement system are elaborated.
First refer to shown in Fig. 3, by chaining pin 41 in kingbolt screw glazing section U1 and the contact of the circumferential edges difference of lower light section U2, to obtain the coordinate of the screw multiple point of light section circumferential edges up and down, through can be calculated light section centre coordinate data under screw glazing section centre coordinate data and screw, so that it is determined that go out screw axle center line position, determining lathe X/Y axle centre coordinate data according to this, now kingbolt screw center centering completes.
Refer to shown in Fig. 4, during the centering of kingbolt screw center, chaining pin 41 is circumferentially taken exercises difference at horizontal plane again, kingbolt plays tooth point position when measuring, and chaining pin 41 does lengthwise movement between the screw thread alveolus in screw.Owing to screw thread alveolus is longitudinal arrangement, the most now measure for horizontal chaining pin.
In Fig. 5, by orientation trouble (measuring required angle), screw axial line will be perpendicular to by machine tool chief axis.Chaining pin 41 is displaced to optional position between screw alveolus subsequently, not contact thread as principle.The most as shown in Figure 6, will move on machine Z-axis, make that chaining pin 41 and alveolus are suitable for reading to contact and record coordinate data now；Afterwards as it is shown in fig. 7, moved down by machine Z-axis, chaining pin 41 is made to contact with alveolus end opening and record coordinate data now.By aforementioned measurement, i.e. can get screw thread spin line and machine tool chief axis orienting station, the unique coordinate point position between machine Z-axis short transverse position, i.e. punctuate coordinate figure shown in Fig. 8.Owing to the distance between adjacent thread is fixing (i.e. pitch is fixing, such as 4mm), therefore according to by measurement to punctuate coordinate figure move the integral multiple of 4mm along Z axis forward and i.e. can get screw thread and play the coordinate figure of tooth point.
By above-mentioned measurement process, can obtain the coordinate figure at the screw center required for repairing screw thread and screw thread plays the coordinate figure of tooth point, screw thread repair process after now installing process tool, can be realized.For ensureing to measure accurately, during measurement must the multi-faceted elaborate manipulation of multiple spot to guarantee that screw thread is accurately repaired.
It should be noted that gauge head 42 introduces negative feedback mechanism during above-mentioned measurement, compensated by calculating, can effectively solve owing to big hanging measures the error problem that the end microtremor caused brings deeply.Additionally, the fixed error of chaining pin 41 and gauge head 42 is stored in industrial computer 1, industrial computer 1 combines the process of fixed error value and obtains accurate actual value the measured value obtained.
By described above, what this utility model was brought has the beneficial effects that: measure level of integrated system high, can realize kingbolt screw center and screw thread plays the quick of tooth point and measures；Using infrared transmission and industrial computer to measure calculating, and introduce negative feedback, solve owing to big hanging measures the error problem that the end microtremor caused brings deeply, measuring speed is fast, and precision is high；Measuring method is simple, easily operates.
Above disclosed it is only this utility model preferred embodiment, certainly can not limit the interest field of this utility model, the equivalent variations therefore made according to this utility model claim with this, still belong to the scope that this utility model is contained.
