Description
Technical field
This utility model relates to technical field of lathe equipment, particularly relates to a kind of lathe positioning and clamping mechanism。
Background technology
In Machinetool workpiece is processed, in major axis, hole machined is difficult point, to ensure the axiality of major axis endoporus and cylindrical on the one hand, also to avoid the heat adding man-hour to make major axis bend thus affecting machining accuracy on the other hand。The clamping device that in current major axis, hole machined adopts is the one end drawing centre of location frame supporting major axis, the other end at major axis is cased with two clips, one clip is connected with the spindle flange of lathe by three extension springs, major axis and the top of grinding machine is made to be in the state of holding out against, another clip is arranged on major axis and top one end contacted, by driving lever, the moment of torsion of spindle flange is transmitted so far clip, thus driving major axis to rotate。This kind of mode complex operation, and the positional precision of major axis cannot be effectively ensured, it is easy to the situation of hole machined deflection in occurring, affect end product quality。
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, a kind of lathe positioning and clamping mechanism is provided, solve the traditional machine tool clamp system in current technology and cannot be effectively ensured the positional precision of major axis when clamping processing major axis, it is easy to the problem that the situation of interior hole machined deflection occurs。
For solving above technical problem, the technical solution of the utility model is:
A kind of lathe positioning and clamping mechanism, including locating centre, it is characterized in that, described locating centre is conical to be fixed on lathe, the axis of locating centre is default localization criteria line, on lathe, the front end of locating centre is additionally provided with the fixing device with locating centre coaxial line, the pretension that the opposite side of fixing device arranges the cone relative with locating centre is top, locating centre device is on support, and pretension is top with locating centre coaxial inner conductor, major axis to be processed is clamped between the two with pretension is top by locating centre, after the axial line of location major axis, major axis is locked by fixing device。Lathe positioning and clamping mechanism described in the utility model is when major axis processed by needs, utilize the locating centre of preset standard axis and pretension is top is clamped between the two by major axis, thus major axis is felt relieved, guarantee that the axial line of major axis is positioned on the axial line that processing is required, thus the axiality of major axis endoporus and cylindrical when ensureing to process, avoid the occurrence of the situation of processing deflection, improve machining accuracy。After axial line of having good positioning, utilizing fixing device to be locked by major axis and keep the position of major axis to change, now removal loads the support that pretension is top, can major axis be processed, convenient to operation。
Further, described pretension is top to be connected with hold-down bolt, screws hold-down bolt and regulates the axial location that pretension is top, convenient by major axis clamping to be processed, simple to operate laborsaving。
Further, in the placing trough that described mount is arranged on lathe, after having positioned, remove support, it is ensured that the top axial line of pretension on support will not find change, so that it is guaranteed that major axis registration, it is ensured that the accuracy of processing。
Further, described fixing device includes the retainer ring of cylindrical shape and tight locking bar, and the circumference of retainer ring offers several screws, in tight lock lever device screw in retainer ring, is gripped by major axis to be processed by screwing the tight locking bar of adjustment。This utility model utilizes tight locking bar can freely screw on the screw of retainer ring, such that it is able to fixed by major axis easily and accurately。
Further, a described tight locking bar end device inside retainer ring has locking block, can be increased the active area of coupling mechanism force by locking block, it is prevented that major axis outer wall is crushed by force localization in a bit, major axis fastening also can be made more firm, it is prevented that major axis rocks simultaneously。
Further, a described tight locking bar end device outside retainer ring screws handle, simple to operate laborsaving。
Compared with prior art, this utility model advantage is in that:
Lathe positioning and clamping mechanism described in the utility model can so that major axis registration, and clamping is stable, thus the accuracy of hole machined in ensureing, it is ensured that major axis endoporus and the axiality of cylindrical, improve end product quality；This utility model simple in construction, easy to operate, save manpower。
