Abstract
The utility model discloses the special production lathe of a kind of oil well instrument, comprises knife rest, the support body of described knife rest is arranged handle of a knife groove, the arranged outside holding piece of handle of a knife groove, and described holding piece is arranged in the holding tank outside handle of a knife groove; Described holding tank is connected with binding groove by guide groove; Described binding groove arranges screw thread, arranges clamping piece in binding groove, described clamping piece diameter and binding groove minor diameter fit; Above described clamping piece, hold-down bolt is set, the threaded engagement of described hold-down bolt and binding groove; In pressing groove below described clamping piece, above the holding piece of guide groove, holding tank, be all full of fluidity rubber.The utility model has the advantages that: the firm grip degree presetting lathe tool by hold-down bolt, when cutter bears the impact that larger run-out tolerance brings, when not reaching cutter or workpiece damage, first the clamping force of clamping is reached, liquid rubber in knife rest produces distortion, makes cutter or workpiece avoid damage.
Description
Technical field
The utility model relates to machining equipment field, is a kind of lathe specifically, is more specifically a kind of cutter frame structure of lathe.
Background technology
Existing lathe saddle structure disclosed in Fig. 1 of Chinese Patent Application No. 201410290242.9, generally adopts bolt fixed cutting tool.The benefit of this structure is adopted to be cutter fixation; But due to oil well instrument, to be generally strip in the majority, and therefore, its axial runout tolerance is comparatively large, and in particular for the downhole tool of maintenance, in production operation, had larger distortion, its jerk value is larger.When keeping in repair, adopting general cutter frame structure, often causing the damage of cutter.
Summary of the invention
For solving the problems of the technologies described above, the utility model disclose a kind of can the knife rest of automatic absorption strain deformation, concrete technical scheme is as follows:
The special production lathe of a kind of oil well instrument, comprise knife rest, it is characterized in that: the support body of described knife rest is arranged handle of a knife groove, the arranged outside holding piece of handle of a knife groove, described holding piece is arranged in the holding tank outside handle of a knife groove; Described holding tank is connected with binding groove by guide groove; Described binding groove arranges screw thread, arranges clamping piece in binding groove, described clamping piece diameter and binding groove minor diameter fit; Above described clamping piece, hold-down bolt is set, the threaded engagement of described hold-down bolt and binding groove; In pressing groove below described clamping piece, above the holding piece of guide groove, holding tank, be all full of fluidity rubber.
The utility model has the advantages that: the firm grip degree presetting lathe tool by hold-down bolt, when cutter bears the impact that larger run-out tolerance brings, when not reaching cutter or workpiece damage, first the clamping force of clamping is reached, liquid rubber in knife rest produces distortion, makes cutter or workpiece avoid damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises knife rest 1, and the support body 1 of described knife rest arranges handle of a knife groove, the arranged outside holding piece 8 of handle of a knife groove, and described holding piece 8 is arranged in the holding tank 4 outside handle of a knife groove; Described holding tank 4 is connected with binding groove 2 by guide groove 6; Described binding groove 2 arranges screw thread, arranges clamping piece 9 in binding groove 2, described clamping piece 9 diameter and binding groove 2 minor diameter fit; Above described clamping piece 9, hold-down bolt 3 is set, the threaded engagement of described hold-down bolt 3 and binding groove 2; In pressing groove below described clamping piece 92, above the holding piece 8 of guide groove 6, holding tank, be all full of fluidity rubber.
Principle of the present utility model is: promote clamping piece 9 when hold-down bolt 3 screws and move downwards, thus compression fluidity rubber, fluidity rubber promotes holding piece 8 and clamps handle of a knife.Owing to presetting chucking power by hold-down bolt 3, and ensure stressed size when chucking power is less than cutter or workpiece damage, therefore when external force does not also damage cutter or workpiece, fluidity rubber produces distortion, cutter can do suitable distortion, has cushioned the impact of external force.Fluidity rubber can adopt model as end sulfydryl (-SH) polysulfide rubber, end carboxyl, hydroxy'terminated butadiene nitrile rubber, terminal isocyanate group polyester and polyethers etc.
The utility model is particularly useful for oil well instrument.
