The angle display device for the digital control tooth milling machine rotary tray apparatus comprises a fixing base (2), a rotary tray (1) and a positioning pin shaft (3). The positioning pin shaft penetrates through the fixing base and the positioning hole of the rotary tray. The rotary tray is positioned on the fixing base. The upper end of the positioning hole of the rotary tray is fixedly connected with a rotary encoder (4). The output shaft of the rotary encoder and the positioning pin shaft are connected by an elastic coupling (6). The positioning pin shaft and the positioning hole of the rotary tray are provided with a needle bearing (5). The utility model adopts the display device, not only improves the angle accuracy of the rotary tray, but also improves the automation content and technical content of the product self.
Description
Technical field
The utility model relates to a kind of angle display unit of numerical control gear milling machine rotation planker.
Background technology
At present, a secondary rotation planker is arranged all in the general mill teeth machine, the determining positions of rotation planker the root angle of mill teeth machine.The mill teeth machine has machinery and numerical control two big classes, but rotation planker wherein all is with manual drives, promptly by an angle scale and a secondary vernier rotation planker is carried out the position and determines.When adopting said method that rotation planker position is determined, the angular resolution equivalent is 1 '--2 ', precision is ± 2 '.Its precision is not high as can be seen, does not have the affluence amount of precision in other words at least.Analyze reason, produce the factor that error mainly contains the following aspects: the error that angle scale and vernier produce in process of manufacture; The error that angle scale and vernier produce in installation process; The error that operating personnel produce because of vision when conversion rotation planker position readings.Simultaneously, owing between rotation planker and alignment pin sliding bearing is installed, making its mutual cooperation is matched in clearance, and this cooperation also can cause the angle precision of rotation planker and the reduction of repeatable accuracy.
Summary of the invention
Technical problem to be solved in the utility model is the angle display unit that a kind of numerical control gear milling machine rotation planker is provided on the basis of above-mentioned rotation planker, the angle display unit of this numerical control gear milling machine rotation planker is when determining rotation planker position, reduce measure error, improved angle precision and repeatable accuracy.
For solving the problems of the technologies described above, the utility model replaces angle scale and vernier with rotary encoder on the basis of original mill teeth machine, comprise holder, rotation planker and alignment pin, alignment pin is passed the locating hole on holder and the rotation planker, the rotation planker is positioned on the holder, the upper end of rotation planker locating hole is fixedly connected with rotary encoder, is connected with yielding coupling between the output shaft of rotary encoder and alignment pin, can remedy the encoder installation errors; Between the locating hole of alignment pin and rotation planker needle bearing is housed, can accomplishes both mutual zero clearance assemblings; Simultaneously operating personnel can be directly digital display meter from the encoder or the display of digital control system read the numerical value of angle, do not had the collimation error.
For the rotary encoder that numerical control gear milling machine is rotated the angle display unit of planker carries out corresponding protection, the rotary encoder protective cover is housed in the outside of rotary encoder.
Because the utility model adopts rotary encoder to substitute original angle scale and vernier, be connected with yielding coupling between the output shaft that cooperates rotary encoder simultaneously and alignment pin, the method of needle bearing is housed between the locating hole of alignment pin and rotation planker, and the error that has fundamentally solved original mill teeth machine rotation planker angle produces.The raising that the introducing of rotary encoder is used angle precision has had corresponding assurance; Between the output shaft of rotary encoder and alignment pin, be connected, can have remedied encoder the error that is produced is installed with yielding coupling; Between the locating hole of alignment pin and rotation planker needle bearing is housed, can makes both accomplish mutual zero clearance assembling; Reading on the rotary encoder shows has eliminated the error that artificial vision produces.Thus, adopt display unit of the present utility model after, not only improved the angle precision of rotation planker, and promoted automation content and the technology content of product itself.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the angle display unit of a kind of numerical control gear milling machine rotation planker of the present utility model.
The specific embodiment
Fig. 1 is the angle display unit of a kind of numerical control gear milling machine rotation planker of the present utility model.This angle display unit comprises holder 2, rotation planker 1 and alignment pin 3 as can be seen from Figure 1, alignment pin 3 is passed the locating hole on holder 2 and the rotation planker 1, rotation planker 1 is positioned on the holder 2, the upper end of rotation planker 1 locating hole is fixedly connected with rotary encoder 4, and 3 of the output shaft of rotary encoder 4 and alignment pin are connected with yielding coupling 6; Between the locating hole of alignment pin 3 and rotation planker 1 needle bearing 5 is housed; In the outside of rotary encoder 4 rotary encoder protective cover 7 is housed.When adopting above embodiment, rotary encoder 4 parameters are chosen as: revolution umber of pulse 3600, precision are ± 1/10 grid, and output signal is sinusoidal wave 1Vpp, I of zero reference point revolution
0Single shaft digital display meter parameter is selected and is set to: metric rotating shaft, feedback signal type are 1Vpp, and inner multiplying power coefficient is 10, can carry out data accumulating and seek zero-bit.Drafting rotation planker 1 angle precision thus is: equivalent＜1 ', precision＜± 1 '.
