Description

High speed high pulling torque direct drive turning workbench
Technical field
The present invention relates to a kind of horizontal Machining centers rotary table, particularly a kind of high speed high pulling torque direct drive turning work Platform.
Background technology
Rotary table is the critical component of horizontal machining center machine, and its design concept directly affects the processing of lathe Performance.The clamp system that current rotary table is used generally has that concentricity is low, clamping force is small, etc. defect, its turn-around machine Structure carries intermediate transmission link to realize that high torque also more, and mechanism is complex and adds the overall weight of workbench, Stage accuracy and speed are directly affected, the market competitiveness of lathe is reduced.
The content of the invention
The present invention relates to one kind it is simple in construction, with electric-machine directly-driven, reduce intermediate transmission mechanism, improve precision and, speed High speed high pulling torque direct drive turning workbench, overcome the deficiencies in the prior art.
The high speed high pulling torque direct drive turning workbench of the present invention, including workbench stage body, the fixation of support works platform stage body Body and bearing with cross roller roller bearing, axle is fixedly connected with the center of workbench stage body, is equipped with and relative can be turned in the outer sheath of axle Dynamic heart axle, the bottom face of heart axle is fixedly connected by ring flange with described fixed body, and being set with mandrel outer can be relative The sleeve of rotation, described bearing with cross roller roller bearing is arranged between workbench stage body, fixed body and sleeve, workbench stage body It is fixedly connected between sleeve, workbench stage body, sleeve and axle can be rotated relative to fixed body simultaneously;
Torque motor stator is fixed with the inside of fixed body, the torque motor rotor matched with torque motor stator passes through connection ring Plate is fixedly connected with described sleeve;
Axostylus axostyle set is set with sleeve, the internal diameter clamp that connects with pneumatic means is set with axostylus axostyle set, internal diameter clamp with Ring flange is fixedly connected;
The bottom head of axle is provided with the angular encoder connected with control device.
The high speed high pulling torque direct drive turning workbench of the invention of the present invention, work is realized using direct drive of torque motor technology The circular index of platform, because not having intermediate transmission link, then coordinates the application of Circular gratings, table positions precision, resetting Precision is high, positioning precision reaches as high as 2 " left and right.And application internal diameter clamp is held tightly, holding mode is simple in construction, compact, response speed Degree is fast, energy-conserving and environment-protective, and hydraulic operation is instead of with mechanical spring action, and reliability is high.Pneumatic clamp is radially holds tightly simultaneously, no Extra axial tension can be brought to work top, the deformation of work top will not be caused, precision stability is high.
Brief description of the drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Embodiment
As shown in Figure 1:3 be workbench stage body, and 13 be the fixed body for the support works platform stage body 3 being fixedly connected with lathe bed, 1 For bearing with cross roller roller bearing.
It is fixedly connected in the centre of workbench stage body 3 by bolt with the upper end of axle 4.It is equipped with the outer sheath of axle 4 Relatively turnable heart axle 8, the bottom face of heart axle 8 is fixedly connected by ring flange 12 with fixed body 13, the bottom face of heart axle 8 with The bolt connection of ring flange 12, ring flange 12 and the bolt connection of fixed body 13.
Relatively turnable sleeve 2 is housed in the outer sheath of heart axle 8, bearing with cross roller roller bearing 1 is arranged on workbench stage body 3rd, between fixed body 13 and sleeve 2, it is fixedly connected between workbench stage body 3 and sleeve 2, workbench stage body 3, sleeve 2 and axle 4 are same When can be rotated relative to fixed body 13.
Torque motor stator 6 is fixed with the inner side of fixed body 13, the torque motor rotor 7 matched with torque motor stator 6 It is fixedly connected by connecting ring flat-plate 5 with sleeve 2.Torque motor rotor 7 is fixedly connected with being connected the bolt of ring flat-plate 5, connection ring flat-plate 5 with The bolt of sleeve 2 is fixedly connected.
Fixed cover covers the internal diameter folder for being set with and connecting with pneumatic means on 10 in axostylus axostyle equipped with axostylus axostyle set 10 on sleeve 2 Pincers 11, internal diameter clamp 11 is bolted to connection with ring flange 12.
The bottom head of axle 4 is provided with the angular encoder 9 connected with control device.
The high speed high pulling torque direct drive turning workbench of the invention of the present invention, during operation, is directly driven by torque motor rotor 7 Moving sleeve 2, workbench stage body 3 are rotated relative to fixed body 13, and rotational angle reads signal by angular encoder 9, pass through control Device command motor is acted or stopped, when workbench stage body 3 is rotated, and pneumatic means is pressed from both sides to the insufflation gas of internal diameter clamp 11, internal diameter Pincers expansion(Internal diameter increases), the clamping to axostylus axostyle set 10 is released, after workbench stage body rotate in place, pneumatic means releases inflation, Make the non-aerating state of internal diameter clamp 11, clamp shaft rod set 10, workbench stage body 3 is fixed.It is real using direct drive of torque motor technology The circular index of existing workbench stage body 3, because not having intermediate transmission link, then coordinates the application of Circular gratings, workbench stage body 3 is determined Position precision, repetitive positioning accuracy are high, positioning precision reaches as high as 2 " left and right.And application internal diameter clamp 11 is held tightly, holds mode knot tightly Structure is simple, compact, fast response time, energy-conserving and environment-protective, and hydraulic operation is instead of with mechanical spring action, and reliability is high.While gas Dynamic clamp will not bring extra axial tension to work top, will not cause the deformation of work top, precision radially to hold tightly Retentivity is high.
