A kind of shaft-like workpiece material fetching mechanism
Technical field:
The utility model relates to material fetching mechanism technical field, refers in particular to a kind of shaft-like workpiece material fetching mechanism.
Background technology:
Machine-building be unable to do without Metal Cutting Machine Tool, and feeding fixture is one of important process device indispensable in the production automation.Machinery Tool Automation fixture is widely used in manufacturing industry, and a large amount of special jig is that production in enormous quantities provides necessary condition.But as you know, be quite huge as axial workpiece application industrially, and its machining accuracy relative requirement is higher.Feeding under normal circumstances for axial workpiece is all by the direct gripping of air cylinder driven fixture, still effective for the product that required precision is so not high like this, but the workpiece relatively high for required precision will cause a large amount of scrapping, the placement precision of material loading workpiece how could be improved when not reducing production effect? therefore we have done following slight improvement to fixture.
Utility model content:
The purpose of this utility model is for the deficiencies in the prior art, and provides a kind of shaft-like workpiece material fetching mechanism, reasonable in design, good stability, the industrial automation axial workpiece material fetching mechanism that gripping precision is high and convenient for installation and maintenance.
For achieving the above object, the utility model adopts following technical scheme, it comprises three-jaw cylinder, buffer spring, spring base, guide finger, workpiece top board, spring bearer plate, feeding tong, spring base is arranged on three-jaw cylinder and passes through screw locking, guide finger is arranged in spring base, wherein one end is spacing by spring base at the spring base other end, buffer spring is arranged between spring base and guide finger, spring bearer plate is arranged on guide finger, workpiece top board is arranged on spring bearer plate, and feeding tong is arranged on three slide blocks of three-jaw cylinder.
The utility model beneficial effect is: spring base is arranged on three-jaw cylinder and passes through screw locking, guide finger is arranged in spring base, wherein one end is spacing by spring base at the spring base other end, buffer spring is arranged between spring base and guide finger, spring bearer plate is arranged on guide finger, workpiece top board is arranged on spring bearer plate, feeding tong is arranged on three slide blocks of three-jaw cylinder, reasonable in design, good stability, the industrial automation axial workpiece material fetching mechanism that gripping precision is high and convenient for installation and maintenance.

Detailed description of the invention:
See shown in Fig. 1,2: the utility model comprises three-jaw cylinder 1, buffer spring 7, spring base 2, guide finger 5, workpiece top board 4, spring bearer plate 3, feeding tong 6, spring base 2 is arranged on three-jaw cylinder 1 and passes through screw locking, guide finger 5 is arranged in spring base 2, wherein one end is spacing by spring base 2 at spring base 2 other end, buffer spring 7 is arranged between spring base 2 and guide finger 5, spring bearer plate 3 is arranged on guide finger 5, workpiece top board 4 is arranged on spring bearer plate 3, and feeding tong 6 is arranged on three slide blocks of three-jaw cylinder 1.
By external agency fixture is transported to and gets workpiece position, first the top of workpiece is withstood by the workpiece top board 4 on fixture, in the process of top tight workpiece, buffer spring 7 can be compressed, can be led by the endoporus of spring base 2, to ensure that buffer spring 7 reaches axial compression by guide finger 5 in the process compressed and spring bearer plate 3 at buffer spring 7.Because workpiece top is withstood by workpiece top board 4, cylinder intake time a little, the slide block on cylinder drives feeding fixture 6 by Workpiece clamping, is finally placed into processing lathe to be processed carrying out workpiece.
Improve as one of the present utility model, described spring base 2 is arranged on three-jaw cylinder 1, passes through screw locking.
Improve as one of the present utility model, described guide finger 5 is arranged in spring base 2, and that large head is spacing by spring base 2 at spring base 2 other end.
Improve as one of the present utility model, described buffer spring 7 is arranged between spring base 2 and guide finger 5, and described spring bearer plate 3 is arranged on guide finger 5, mainly in order to the reply guiding after compressing buffer spring 7.
Improve as one of the present utility model, described workpiece top board 4 is arranged on spring bearer plate 3, allows spring bearer plate 3 pairs of buffer springs 7 compress by screw-threaded coupling on guide finger 5.
Improve as one of the present utility model, described feeding tong is arranged on the slide block of three-jaw cylinder 1, when completing the effect of gripping workpiece after cylinder ventilation.
The above is only preferred embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
