Lathe fixture can prevent the deformation when thin wall class ring work piece dress card, reduces the rejection rate.
Description
Technical Field
The utility model belongs to the technical field of the machine-building, especially, relate to a lathe fixture.
Background
The lathe is a machine tool for turning a rotating workpiece by mainly using a lathe tool, has wide processing objects, large adjustment range of the rotating speed and the feed quantity of a main shaft, can process the inner and outer surfaces, the end surfaces and the inner and outer threads of the workpiece, and is widely applied to various machining workshops. However, when thin-walled circular ring workpieces are machined, if the three-jaw chuck is used for directly clamping, the workpieces are easy to deform, and the rejection rate is increased.
Disclosure of Invention
To the problem that prior art exists, the utility model provides a turning attachment.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a lathe fixture, includes the support disc, a fixed cylindric fixed clamp splice that is provided with of terminal surface of support disc, fixed clamp splice and the coaxial setting of support disc, another terminal surface of support disc is provided with a plurality of spouts of seting up along its direction of radius, the spout sets up along the circumferencial direction equipartition, and runs through the support disc along the axial, be provided with L shape jack catch in the spout, L shape jack catch inserts support disc end and runs through and has seted up the adjustment tank, the exposed protrusion end of L shape jack catch sets up along the direction of keeping away from the support disc centre of a circle, be provided with adjusting bolt on the lateral wall of support disc, adjusting bolt's one end runs through the adjustment tank of L shape jack catch to be provided with the anti-drop fixture block at this tip, threaded connection between adjusting bolt and the support.
The number of the sliding grooves is three or four.
The utility model has the advantages that:
the utility model provides a turning attachment is provided with L shape jack catch along the circumferencial direction equipartition on this turning attachment, when dress card thin wall ring class work piece, uses the fixed terminal surface that steps up the work piece of L shape jack catch, rather than dress card thin wall periphery to can effectively avoid the work piece to take place to warp when the dress card, reduce the rejection rate.
Drawings
FIG. 1 is a schematic structural view of the lathe fixture of the present invention;
FIG. 2 is a left side view of FIG. 1;
in the figure: 1-supporting disc, 2-fixing clamp block, 3-sliding groove, 4-L-shaped clamping jaw, 5-adjusting groove, 6-adjusting bolt and 7-anti-falling clamp block.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, a lathe fixture belongs to the technical field of machine manufacturing, and can prevent a thin-wall circular workpiece from deforming during clamping and reduce the rejection rate.
The utility model discloses a turning attachment, including supporting disc 1, a fixed cylindric fixed clamp splice 2 that is provided with of terminal surface of supporting disc 1, fixed clamp splice 2 with support the coaxial setting of disc 1, fixed clamp splice 2 is convenient for block this turning attachment on the three-jaw chuck of lathe. The other end face of the supporting disc 1 is provided with a plurality of sliding grooves 3 which are formed along the radius direction of the supporting disc, the sliding grooves 3 are uniformly distributed along the circumferential direction and penetrate through the supporting disc 1 along the axial direction, and the sliding grooves 3 can enable the L-shaped clamping jaws 4 to move along the radius direction, so that the clamping of the circular workpiece is facilitated. An L-shaped clamping jaw 4 is arranged in the sliding groove 3, and the L-shaped clamping jaw 4 is used for clamping and fixing a circular ring workpiece. The L-shaped clamping jaw 4 is inserted into the end of the supporting disc 1 and penetrates through to be provided with an adjusting groove 5, and the adjusting groove 5 can enable the L-shaped clamping jaw 4 to move back and forth relative to the adjusting bolt 6, so that the clamping device is convenient to adapt to clamping of workpieces with different thicknesses. The exposed protruding end of the L-shaped clamping jaw 4 is arranged along the direction far away from the circle center of the supporting disc 1, an adjusting bolt 6 is arranged on the side wall of the supporting disc 1, one end of the adjusting bolt 6 penetrates through an adjusting groove 5 of the L-shaped clamping jaw 4, an anti-falling clamping block 7 is arranged at the end part of the adjusting bolt, the anti-falling clamping block 7 is matched with the adjusting bolt 6 and used for locking the L-shaped clamping jaw 4, and meanwhile, the adjusting groove 5 of the L-shaped clamping jaw 4 can be prevented from falling off from the bottom of the adjusting. The adjusting bolt 6 is in threaded connection with the supporting disk 1.
The quantity of spout 3 is three or four, and the jack catch of this quantity can make the dress card stability of work piece better, and too much makes the adjustment installation more loaded down with trivial details, and too little then stability support nature is relatively poor.
The following describes the usage of the present invention with reference to the drawings.
The method comprises the following steps: inserting and fixing the fixed clamping block 2 on a three-jaw chuck of a lathe;
step two: screwing the circumferential adjusting bolt 6 in to enable the L-shaped clamping jaw 4 to be convenient for loading;
step three: sleeving a thin-wall circular workpiece to be processed on the L-shaped clamping jaw 4;
step four: adjusting the relative position of the L-shaped clamping jaw 4, and screwing the adjusting bolt 6 to tightly clamp the L-shaped clamping jaw 4 and the workpiece;
step five: and starting the lathe for processing.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
