Abstract
The utility model discloses a workpiece pressing clamp, which comprises a clamp table (1), a cylinder (2) and a press plate (6). The workpiece pressing clamp is characterized by further including a guide sleeve (3), a fixing seat (4), a guiding pin (5) and a press plate locking device, the guide sleeve (3) is mounted on a cylinder shaft (2.1) of the cylinder (2), the fixing seat (4) fixes the guiding sleeve (3) onto the clamp table (1), the guiding sleeve (3) is provided with a guiding groove (3.1) provided with a spiral groove portion (3.1.1) and a straight groove portion (3.1.2), the guiding pin (5) penetrating through the guiding groove (3.1) is fixed onto the cylinder shaft (2.1), and the press plate (6) is tightly locked at the end of the cylinder shaft (2.1) by the press plate locking device. The workpiece pressing clamp can enable the press plate fixedly mounted on the cylinder shaft to deviate to one side so that a workpiece receives larger space in the vertical direction on the clamp table to facilitate operation, thereby greatly improving mounting and clamping speed.
Description
Technical field
The utility model relates to a kind of anchor clamps, specifically is meant a kind of Workpiece-pressing jig.
Background technology
When the machining of parts, generally want elder generation that workpiece is positioned and compress.What workpiece clamping mode commonly used at present adopted usually is to adopt nut bolt to be fixed, though this mode is easy, but comparatively waste time and energy when being to use, a kind of compressing fixture that utilizes cylinder locking has also appearred at present, it utilizes cylinder to come workpiece pressing as power, and a kind of common structure is as follows: the end at cylinder axis is mounted with pressing plate, when cylinder is opened workpiece is installed in the below of pressing plate, after the location finished, cylinders retract was with Work-sheet pressing.Though this structure has improved the speed of clamping and more laborsaving than traditional nut bolt fixed form to a certain extent, but in use, because workpiece will be placed on the below of pressing plate, pressing plate is as essential parts, in a narrow and small clamping space, but influenced clamping speed, thereby, need improve speed to this compressing fixture with further raising clamping.
The utility model content
The technical problems to be solved in the utility model provides the Workpiece-pressing jig that a kind of clamping speed improves greatly.
Technical solution adopted in the utility model provides a kind of Workpiece-pressing jig with following structure.
A kind of Workpiece-pressing jig, comprise anchor clamps platform, cylinder and pressing plate, also comprise guide pin bushing, holder, guide finger and pressing plate locking device, guide pin bushing is contained on the cylinder axis that cylinder has, holder is fixed on guide pin bushing on the anchor clamps platform, and described guide pin bushing has gathering sill, and gathering sill has spiral slot part and straight trough portion, described guide finger passes gathering sill and is fixed on the cylinder axis, and described pressing plate is locked at the end of cylinder axis by the pressing plate locking device.
By above scheme, owing to have gathering sill being provided with on the cylinder axis on guide pin bushing and the guide pin bushing, when cylinder is opened or is withdrawn, be fixed on that guide finger forces cylinder axis to turn an angle on the cylinder axis under the guide effect of gathering sill, like this when workpiece is installed, can set the length of gathering sill spiral slot part as required so that the pressing plate that is fixed on the cylinder axis can secundly, make workpiece on the anchor clamps platform, obtain the bigger space of vertical direction, make things convenient for operation, thereby can improve the speed of clamping greatly.
As preferably, described pressing plate locking device comprises nut and lock(ing) bolt, and described pressing plate has spherical groove, described nut has and the corresponding spherical of groove, adopt the spherical clamping platen, can better guarantee the flatness of pressing plate, thereby can guarantee the positioning accuracy of workpiece.
As improvement; described guide pin bushing outside also is provided with outer cover; also be provided with sealing ring between described outer cover and the cylinder axis; this is provided with and can protects guide pin bushing; to prevent that part processing was produced in workpiece process iron filings, aluminium bits etc. from falling in the guide pin bushing; influenced the smooth degree that moves up and down of cylinder, this outer cover also can carry out hiddenly to key structure of the present utility model simultaneously, can also prevent that to a certain extent structure from divulging a secret.
As preferably, the angle that 1/4th of the cylinder axis circumference that described spiral slot part is crossed over, this preferred version can make cylinder rotate is 90 °, and promptly pressing plate can transfer parallel position to from vertical position when clamping, making pressing plate avoid installing space when workpiece is installed, is a kind of technical scheme of the best.
Description of drawings
Accompanying drawing is the structural representation of the utility model Workpiece-pressing jig.
Shown in the figure:
1, anchor clamps platform 2, cylinder 2.1, cylinder axis 3, guide pin bushing 3.1, gathering sill 3.1.1, spiral slot part 3.1.2, straight trough portion 4, holder 5, guide finger 6, pressing plate 7, nut 8, lock(ing) bolt 9, outer cover 9.1, sealing ring
The specific embodiment
The specific embodiment of the present utility model is described in detail the technical solution of the utility model for better illustrating below in conjunction with accompanying drawing.
As shown in the drawing, a kind of Workpiece-pressing jig, comprise anchor clamps platform 1, cylinder 2 and pressing plate 6, also comprise guide pin bushing 3, holder 4, guide finger 5 and pressing plate locking device, guide pin bushing 3 is contained on the cylinder axis 2.1 that cylinder 2 has, holder 4 is fixed on guide pin bushing 3 on the anchor clamps platform 1, described guide pin bushing 3 has gathering sill 3.1, gathering sill 3.1 has spiral slot part 3.1.1 and the 3.1.2 of straight trough portion, / 4th of a cylinder axis circumference that the spiral slot part is crossed over, described guide finger 5 passes gathering sill 3.1 and is fixed on the cylinder axis 2.1, described guide pin bushing 3 outsides also are provided with outer cover 9, also be provided with sealing ring 9.1 between described outer cover and the cylinder axis, described pressing plate locking device comprises nut 7 and lock(ing) bolt 8, described pressing plate 6 has spherical groove, and described nut 7 has and the corresponding spherical of groove, and described pressing plate 6 is locked at the end of cylinder axis 2.1 by the pressing plate locking device.
When clamping workpiece, cylinder is opened, cylinder axis drives pressing plate under the spiral fluted guide effect that has on the guide pin bushing, pop up and turn to the parallel position of workpiece, can be installed in workpiece on the anchor clamps platform easily this moment, installs cylinders retract, cylinder axis drives pressing plate under the spiral fluted guide effect that has on the guide pin bushing, falls and turn to the vertical position of workpiece with Work-sheet pressing downwards.
When reality is used, can use a plurality of work piece holders of the present utility model simultaneously, particularly with the control of cylinder automatic control system, can further improve the speed of clamping workpiece in conjunction with process equipment.
In the above-described embodiments, preferred forms of the present utility model is described, obviously, under inventive concept of the present utility model, still can make a lot of variations, as the angle of helicla flute spiral, direction etc. processing can be set according to actual needs all, and for example guide finger also can use riveted joint as required with the mode of fixedlying connected of cylinder axis, mode such as be threaded.At this, should illustrate that any change of being made all will fall in the protection domain of the present utility model under inventive concept of the present utility model.
