Description
Technical field
The utility model belongs to machining frock class, specifically a kind of work pieces process expander positioner.
Background technology
Machining generally adopts plain shaft structure to carry out the locating and machining of workpiece, has the advantages such as structure is simple, easy to operate, difficulty of processing is low, but due to the impact of manufacturing and fixing error, causes the positioning precision of workpiece low, had a strong impact on crudy.Owing to adopting the locate mode of plain shaft structure, effectively cannot absorb the mismachining tolerance of frock and the clamping error of workpiece, the precision uniformity of workpiece in process is difficult to ensure, easily causes workpiece accuracy overproof and generation is scrapped.
Summary of the invention
The purpose of this utility model is the deficiency existed for conventional workpiece processing and positioning device, proposes a kind of work pieces process expander positioner, effectively improves the positioning precision of workpiece, thus improves the machining accuracy of workpiece.
The utility model is achieved through the following technical solutions:
A kind of work pieces process expander of the utility model positioner, comprise expansion set, base, locating flange, pull bar transit joint, drive screw, it is characterized in that: pull bar transit joint is arranged on locating flange, drive screw is enclosed within base and pull bar transit joint, expansion set is fixed on pull bar transit joint, drive screw drives pull bar transit joint and expansion set along drive screw axially-movable, and expansion set is with the conical surface, and between base, taper-face contact realizes the conical surface and swells and locate.
Drive screw of the present utility model installs Thrust nut, and drive screw carries out the spacing of stroke by Thrust nut.
The utility model expansion set is fixed on pull bar transit joint by bolt, lining, and carries out the adjustment of setting height(from bottom) by lining.
The utility model base installs interchangeable support pad, installs fixed support pad between interchangeable support pad and base, the combination of fixed support pad and interchangeable support pad realizes the location of different workpieces.
The utility model adopts the location structure of expander, effectively can improve the positioning precision of workpiece, improve the machining accuracy of workpiece.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model expansion set structural representation.
Fig. 3 is the utility model expansion set sectional view.
Detailed description of the invention
As shown in Figure 1, a kind of work pieces process expander positioner, comprise expansion set 1, base 2, interchangeable support pad 3, fixed support pad 4, locating flange 5, lining 6, pull bar transit joint 7, Thrust nut 8, drive screw 9, dust-proof plug screw 10, bolt 11, it is characterized in that: Thrust nut 8 is arranged on drive screw 9, pull bar transit joint 7 is arranged on locating flange 5, expansion set 1 is by bolt 11, lining 6 is fixed on pull bar transit joint 7, drive screw 9 is enclosed within base 2 with on pull bar transit joint 7, dust-proof plug screw 10 is arranged on base 2, fixed support pad 4 is arranged between interchangeable support pad 3 and base 2.
Drive screw 9 of the present utility model carries out the spacing of stroke by Thrust nut 8.
The utility model expansion set 1 carries out the adjustment of setting height(from bottom) by lining 6.
The utility model drives pull bar transit joint 7 and expansion set 1 along drive screw 9 axially-movable by drive screw 9, and if Fig. 2 and Fig. 3 is the structural representation of expansion set 1, expansion set 1 is with the conical surface, and between base 2, taper-face contact realizes the conical surface and swells and locate.
The utility model base 2 is provided with interchangeable support pad 3, between interchangeable support pad 3 and base 2, fixed support pad 4 is installed, the location of different workpieces can be realized by fixed support pad 4 and the combination of interchangeable support pad 3.
