Abstract
The utility model belongs to the control gear field of lathe, specifically discloses a kind of machine tool fixture drive unit, comprises single cylinder, piston is provided with in this cylinder, piston is connected with piston rod, and the output terminal of cylinder is connected with and turns to cylinder, and piston rod turns to an outputting power to running through this; The free end of piston rod is connected with bent untie-sell, and rotary cylinder axially has the bent action-oriented groove of S type, and bent untie-sell is inserted in this bent action-oriented groove and the diameter of this bent untie-sell is identical with the groove width of bent action-oriented groove.The utility model can workpiece loading and unloading on machine tool fixture fast, saves time, without the need to peripheral hardware fixture pushing mechanism.
Description
Technical field
The utility model belongs to the control gear field of lathe.
Background technique
In existing machinery industry, be all need first it to be fixedly clamped on lathe to process certain component, carrying out cutting, company, the machining operation such as milling flat.In existing machine tool fixture, general employing cylinder or hydraulic oil cylinder driving fastening device clamp workpiece, existing fastening device such as pneumatic pressure mouthes etc. all adopt and move axially to realize compressing, its shortcoming is: because fastening device is positioned at the top of fixture, workpiece can only operate from fixture side when installing and removing workpiece, or increase a fixture pushing mechanism in the side of fastening device, when engineering is installed and removed, fastening device is first passed, abdicate the mounting or dismounting position of workpiece.
Model utility content
The utility model is intended to provide a kind of and rotates and abdicate the machine tool fixture drive unit in dismounting room when ensureing that fastening device moves axially.
The purpose of this utility model can be reached by following scheme: machine tool fixture drive unit, comprise single cylinder, be provided with piston in this cylinder, piston is connected with piston rod, the output terminal of cylinder is connected with and turns to cylinder, and piston rod turns to an outputting power to running through this; The free end of piston rod is connected with bent untie-sell, and rotary cylinder axially has the bent action-oriented groove of S type, and bent untie-sell is inserted in this bent action-oriented groove and the diameter of this bent untie-sell is identical with the groove width of bent action-oriented groove.
Technique scheme difference with the prior art is: arrange in the termination of cylinder output shaft and turn to cylinder, turn on cylinder and be provided with bent action-oriented groove, during cylinder action, piston rod moves axially, bent untie-sell on piston rod is moved in bent action-oriented groove, because bent action-oriented groove is S-type, therefore the while that piston rod moving axially, shaft rotates, also rotate when the machine tool fixture main shaft be connected with piston rod output terminal is moved axially, if located when workpiece is and relies on machine tool fixture to press down, so machine tool fixture main shaft moves and unclamp workpiece, main shaft laterally rotates abdicates dismounting station, workpiece is made to be quickly removed.The utility model can workpiece loading and unloading on machine tool fixture fast, saves time, without the need to peripheral hardware fixture pushing mechanism.
Further, the output terminal of described cylinder has the piston hole passed for piston rod, and this piston hole and piston rod packing seal, and preventing the Leakage Gas in cylinder to turning in cylinder, affecting the output of cylinder.
Further, described bent untie-sell head with connecting ring, the axis of this connecting ring and the axially mutually vertical of bent untie-sell, connecting ring and piston rod are bolted to connection, and connect more firm.
Further, described in turn to cylinder and cylinder one-body molded, process convenient, there is good sealing.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the utility model machine tool fixture drive unit embodiment;
Fig. 2 is the sectional structure schematic diagram of the utility model machine tool fixture drive unit embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference character in Figure of description comprises: 1-shell; 2-output terminal end plate; 3-piston rod; 4-first air ports; 5-second air ports; The bent untie-sell of 6-; 7-connecting ring; The bent action-oriented groove of 8-.
Embodiment is substantially as shown in Figure 1 and Figure 2: machine tool fixture drive unit, and comprise a columnar shell 1, this shell 1 is divided into two sections, respectively as single-acting cylinder cylinder shell and the barrel shell turning to cylinder.The two ends of single-acting cylinder are welded with output terminal end plate 2, tail end end plate respectively, the internal engagement of single-acting cylinder has piston, this piston is threaded with piston rod 3, the output terminal end plate 2 of single-acting cylinder has piston hole, piston rod 3 run through this piston hole and with output terminal end plate 2 packing seal, single-acting cylinder cylinder shell has the first air ports 4 and the second air ports 5.
Turn to cylinder and single-acting cylinder to be close to, from single-acting cylinder, out axially run through this turns to cylinder to piston rod 3 afterwards, and the free end of piston rod 3 is coaxially fixedly connected with machine tool fixture main shaft, and the movement of machine tool fixture main shaft can drive clamp and unclamp workpiece.The shaft of piston rod 3 is fixed with bent untie-sell 6, this bent untie-sell 6 head is welded to connect ring 7, and the axis of this connecting ring 7 is mutually vertical with the axis of bent untie-sell 6, and connecting ring 7 and piston rod 3 are bolted to connection; Rotary cylinder axially has the bent action-oriented groove 8 of S type, bent untie-sell 6 is inserted in this bent action-oriented groove 8, the diameter of this bent untie-sell 6 is identical with the groove width of bent action-oriented groove 8, the movement of piston rod 3 then makes bent untie-sell 6 mobile in bent action-oriented groove 8, thus piston rod 3, machine tool fixture main shaft are rotated, the rotation of machine tool fixture main shaft can make fixture outward winding from workpiece, abdicates installation or removal station.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
