Abstract
The utility model discloses a four times 90 degree positioning device for a rotating table, comprising a positioning flange, a positioning rod and a driving device, wherein the positioning flange is provided with a vertical positioning hole and an assembly structure used for vertically installing an axial line on the rotating table for four times 90 degree standard positioning; the positioning rod is provided with a support seat which needs to be installed on a supporting plate of a machine tool so that the axial line of the positioning rod can be positioned on a cylindrical surface adopting an axis of the rotating table as a rotating axis and the axial line of the positioning flange as a generatrix, and axial direction for the positioning rod is formed by the support seat; and the driving device is used for driving the positioning rod to move in the axial direction thereof so that the positioning rod can be inserted into or separated from the positioning hole. The four times 90 degree positioning device for the rotating table is convenient to operate and capable of realizing accurate positioning.
Description
Technical field
The utility model relates to 4 * 90 ° of positioners of a kind of rotary table, particularly is applicable to the location of rotary table that numerical control floor type boring and milling machine is joined.
Background technology
Location for 4 * 90 ° of rotary tables has usually than high orientation precision, and known locate mode has taper pin location structure, scale location structure etc. usually, and the former operates inconvenience, and the latter has relatively high expectations to operating personnel's level.In addition, known locate mode human factor is many, has increased working strength of workers, and the location is not necessarily very accurate.
Summary of the invention
Therefore, it is a kind of easy to operate that the purpose of this utility model is to provide, 4 * 90 ° of positioners of the rotary table of accurate positioning.
The technical solution adopted in the utility model is:
4 * 90 ° of positioners of the utility model rotary table, it comprises:
Locating flange has vertical locating hole and is used for the assembly structures that its axis is installed on 4 * 90 ° of demarcation positions of rotary table vertically;
Backstay is furnished with bearing, and this bearing is used to be installed on the supporting plate of lathe, and the axle that the backstay axis is dropped on rotary table is gyroaxis, is on the face of cylinder of bus with the locating flange axis that bearing forms axial guiding to backstay simultaneously; And
Drive unit drives described backstay in its axial motion, makes the backstay insertion or breaks away from described locating hole.
4 * 90 ° of positioners of rotary table according to technical solutions of the utility model, under user mode, be furnished with four locating flanges, be installed in the demarcation position of workbench respectively, as long as locating flange and described backstay are used, just can carry out accurate in locating so at a certain demarcation position.And positioning action only needs the driving of drive unit, and is easy and simple to handle.
4 * 90 ° of positioners of above-mentioned rotary table, described backstay is the piston rod of a fluid cylinder, and described bearing is the cylinder body of corresponding described fluid cylinder then, and correspondingly, described drive unit has constituted the fluid control piper of described fluid cylinder.
4 * 90 ° of positioners of above-mentioned rotary table also comprise the travel control device of described backstay.
4 * 90 ° of positioners of above-mentioned rotary table, described formation control device comprise the system son that is arranged on the backstay and be arranged on the frame near switch, this is connected to described drive unit near switch.
Description of drawings
Below in conjunction with Figure of description in detail the technical solution of the utility model is described in detail, wherein:
Fig. 1 be according to 4 * 90 ° of positioner user modes of a kind of rotary table of technical solutions of the utility model structural representation.
Among the figure: 1, locating flange, 2, backstay, 3, bearing, 4, sliding ring, 5, joint and oil pipe, 6, joint and oil pipe, 7, dust seal, 8, near switch, 9, system; A, supporting plate, b, workbench.
The specific embodiment
With reference to explanation accompanying drawing 1, it shows 4 * 90 ° of positioners of a kind of rotary table, and it comprises:
Locating flange 1 has vertical locating hole and is used for the assembly structures that its axis is installed on 4 * 90 ° of demarcation positions of rotary table vertically;
Backstay is furnished with bearing 3, and this bearing is used to be installed on the supporting plate a of lathe, and the axle that the backstay axis is dropped on rotary table is gyroaxis, is on the face of cylinder of bus with the locating flange axis that bearing forms axial guiding to backstay simultaneously; And
Drive unit drives described backstay in its axial motion, makes the backstay insertion or breaks away from described locating hole.
About described drive unit, purpose is to realize the axial motion of described backstay, and just a kind of rectilinear motion in machinery, realizes that straight-line mechanism or kinematic pair are a kind of basic driving mechanism or kinematic pair, manufactures and designs simple.Certainly, backstay and drive unit can constitute an integral body fully, the fluid cylinder as shown in accompanying drawing 1.So described backstay is the piston rod of a fluid cylinder, and described bearing is the cylinder body of corresponding described fluid cylinder then, and correspondingly, described drive unit has constituted the fluid control piper of described fluid cylinder.The shape process control of fluid cylinder only needs just can realize by the fluid flow of controlling its control piper, and the speed of piston rod, the speed that can control fluid realizes, based on the design of this programme, implements also very easy.
Further, in order to improve control accuracy, this device also comprises the travel control device of described backstay, and as previously mentioned, Stroke Control can certainly, also can adopt outside control by the control of drive unit self control system.Form as described control device comprise the system son 9 that is arranged on the backstay and be arranged on the frame near switch 8, this is connected to described drive unit near switch.
Fluid cylinder as shown in Figure 1 is a kind of more typical hydraulic cylinder, and its piston rod leans out from rear end cap, is used for installing system 9, certainly, system 9 can be set also in the part that piston rod leans out from drive end bearing bracket.
