Abstract
The utility model discloses a speed feedback mechanism of a worktable of a vertical type lathe. The worktable (1) is mounted on a main shaft (4) which is fixedly arranged; the worktable (1) is driven through a rotary driving mechanism; the main shaft (4) is provided with a rotary encoder (5); and a signal circuit of the rotary encoder (5) is connected with an electric control system of the vertical type lathe. With the adoption of the technical scheme, the mounting and positioning precision of a speed measuring mechanism is high and the speed measuring mechanism is convenient to machine and manufacture; and after the vertical type lathe of a numerical control cutter rest is mounted on the set of an encoder mechanism, the threading function can be realized.
Description
Technical field
The utility model belongs to the technical field of metal cutting machining tool, relates to the transmission mechanism of the workbench of vertical lathe, and more particularly, the utility model relates to a kind of vertical lathe workstation speed feedback mechanism.
Background technology
In the prior art, the workbench of vertical lathe rotatablely move and the feed motion of knife rest between be transmission mechanism independently mutually owing to there is not the relation of driving-chain, gearratio between the two can't guarantee.Because vertical lathe can not guarantee screw thread and process the gearratio of the strictness between the feed motion of desired workpiece rotation and cutter, just can't process for the screw thread of large-scale workpiece.
The utility model content
The utility model provides a kind of vertical lathe workstation speed feedback mechanism, its objective is the processing that on vertical lathe, realizes screw thread.
To achieve these goals, the technical scheme taked of the utility model is:
The vertical lathe workstation speed feedback mechanism that the utility model provided; Described workbench is installed on the main shaft that fixedly installs; Described workbench drives through rotary drive mechanism; Described main shaft is provided with rotary encoder, and the signal circuit of described rotary encoder is connected with the electric control system of described vertical lathe.
Described workbench is installed on the main shaft through tapered sleeve, gland and radial bearing and thrust bearing; Described main shaft is fixedly mounted on the pedestal; The center of described main shaft is provided with fixed cap, and the body-fixed of described rotary encoder is installed on the described fixed cap; Swivelling cover is equipped with at center at described gland, on described swivelling cover, locating shaft is housed, and described locating shaft is connected with the rotating part of described rotary encoder.
The utility model adopts technique scheme, and the installing and locating precision of its velocity measurement mechanisms is high, is convenient to processing and manufacturing, and the numerically-controlled slide vertical lathe just can be realized the function of cutting thread after this cover code device is installed.
Description of drawings
Briefly explain in the face of the expressed content of the accompanying drawing of this specification and the mark among the figure down:
Fig. 1 is the structural representation of the utility model.
Be labeled as among the figure:
1, workbench, 2, tapered sleeve, 3, gland, 4, main shaft, 5, rotary encoder, 6, locating shaft, 7, shaft coupling, 8, swivelling cover, 9, fixed cap, 10, pedestal.
The specific embodiment
Contrast accompanying drawing below,, the specific embodiment of the utility model is done further detailed explanation, inventive concept, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art through description to embodiment.
Like the structure of the expressed the utility model of Fig. 1, the utility model is an a kind of vertical lathe workstation speed feedback mechanism, and described workbench 1 is installed on the main shaft 4 that fixedly installs, and described workbench 1 drives through rotary drive mechanism.Main shaft 4 is fixed on the pedestal 10; Cylindrical roller bearing and single direction thrust ball bearing are housed on the main shaft 4.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, be implemented in the goal of the invention that realizes the processing of screw thread on the vertical lathe, the technical scheme that the utility model is taked is:
Vertical lathe workstation speed feedback mechanism as shown in Figure 1, that the utility model provided, described main shaft 4 is provided with rotary encoder 5, and the signal circuit of described rotary encoder 5 is connected with the electric control system of described vertical lathe.
Be shown in the figure that the vertical lathe workstation main shaft installs the structure of rotary encoder, rotary encoder 5 has been installed after, be equipped with the processing that numerically-controlled slide just can be realized screw thread.
The concrete structure of the utility model is following:

Workbench 1 rotation then drives tapered sleeve 2, gland 3, swivelling cover 8, locating shaft 6 and rotates together, and locating shaft 6 rotates through the rotating shaft that shaft coupling 7 drives encoder 5, and encoder 5 sends signal of telecommunication work like this.
The working method of the utility model is following:
Gland 3 is arranged on the bearing, through the screw on the turn gland 3, workbench 1 and tapered sleeve 2 are fitted tightly, workbench 1 rotation then drives tapered sleeve 2, gland 3 and rotates together; A fixed cap 9 is equipped with at the center of main shaft 4; Rotary encoder 5 just is installed on the fixed cap 9; At the center of gland 3 swivelling cover 8 is housed, locating shaft 6 is housed on it, workbench 1 rotation then drives tapered sleeve 2, gland 3, swivelling cover 8, locating shaft 6 and rotates together; Locating shaft 6 rotates through the rotating shaft that shaft coupling 7 drives encoder 5, and encoder 5 sends signal of telecommunication work like this.
The installing and locating precision of this cover mechanism is high, is convenient to processing and manufacturing, and the numerically-controlled slide vertical lathe just can be realized the function of cutting thread after this cover code device is installed.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
