Description
technical field:
The utility model belongs to jig field, relates to the self-driven supplemental support unit of a kind of jig
,particularly relate to a kind of jig self-driven dovetail groove Wedge type supplemental support unit.
background technology:
at present, supplemental support for supporting workpiece in jig of the prior art, substantially be divided into two kinds: one is Manual auxiliary support device, this supplemental support needs manual operation, but due to inefficiency, labour intensity is large, and is not suitable for the needs of full-automatic machine tool, and this device is in the trend be eliminated gradually; Another kind is automatic auxiliary support apparatus, the structure of this device has three large nucleus modules, first nucleus module is the locking module after supplemental support puts in place, it is mainly divided into two kinds, wherein one relies on resilient sleeve to hold auxiliary support bar tightly, because in use resilient sleeve easily produces expendable plastic deformation, and then cause the situation that can not hold tightly and affect use, so be not very reliable.Another is the mode relying on oil pressure to hold out against wedge locking auxiliary support bar all the time, and this kind of mode is with the fluctuation of oil pressure, and supplemental support pressure also can produce fluctuation, easily causes supplemental support to lose efficacy.Second nucleus module drives wedge to hold out against auxiliary support bar module, drive wedge mainly to rely on external oil cylinder to realize, but external oil cylinder floor space is comparatively large in prior art, makes supplemental support module whole volume too large, be unfavorable for the layout in fixture.3rd nucleus module is the device that auxiliary support bar is resetted, and mainly relies on spring reset in prior art, but due to the more difficult control of spring force, and spring in use easily follows the string, so rely on spring reset not to be very reliable.Need now a kind of volume badly little, resetted reliable, and can the supplemental support module of positive lock auxiliary support bar, support workpiece that can be stable in process, ensures machining accuracy.
Utility model
content:
It is little that the purpose of this utility model is to provide a kind of volume, resets reliable, and can positive lock auxiliary support bar, and support workpiece that can be stable in process, ensures the jig self-driven dovetail groove Wedge type supplemental support unit of machining accuracy
The technical solution of the utility model is: jig self-driven dovetail groove Wedge type supplemental support unit, comprising: supplemental support cell cube, bonnet, pipe joint, an O RunddichtringO, the 2nd O RunddichtringO, dovetail groove type wedge, the 3rd O RunddichtringO, pilot bushing, bulb support nail, auxiliary support bar, dust ring, protective cover; Dovetail groove type wedge coordinates and is arranged in the endoporus of supplemental support cell cube, and dovetail groove wedge can left and right movement in supplemental support cell cube; Bonnet is arranged in the endoporus of supplemental support cell cube one end, pipe joint to be arranged on bonnet and to be connected with supplemental support cell cube, the supplemental support cell cube other end installs protective cover, pilot bushing is arranged on supplemental support cell cube top, the outer dovetail cooperation of auxiliary support bar bottom is arranged on the interior dovetail groove of dovetail groove type wedge, the cylindrical cooperation of auxiliary support bar is arranged on the endoporus of pilot bushing, the relative pilot bushing of auxiliary support bar can do relative linear motion, and bulb support nail is fixedly mounted on auxiliary support bar.
2nd O RunddichtringO, the 3rd O RunddichtringO are installed in the groove of dovetail groove type wedge; One O RunddichtringO is installed in the groove of bonnet; In the groove of pilot bushing, dust ring is installed.
The utility model can reach following beneficial effect after adopting technique scheme: this self-driven dovetail groove Wedge type supplemental support unit, integrated level is high, floor space is little, reset reliable, auxiliary support bar positive lock can be guaranteed in process, thus ensure stable support workpiece, guarantee not occur the situations such as vibration in process, and then improve machining accuracy.
accompanying drawing illustrates:
Fig. 1 is the main TV structure schematic diagram of the utility model jig self-driven dovetail groove Wedge type supplemental support unit.
Fig. 2 is the A-A partial schematic sectional view of the utility model jig self-driven dovetail groove Wedge type supplemental support unit.
detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention will be further described.As depicted in figs. 1 and 2: jig self-driven dovetail groove Wedge type supplemental support unit, supplemental support cell cube 1, bonnet 2, pipe joint 3, an O RunddichtringO 4, the 2nd O RunddichtringO 5, dovetail groove type wedge 6, the 3rd O RunddichtringO 7, pilot bushing 8, bulb support nail 9, auxiliary support bar 10, dust ring 11, protective cover 12, it is characterized in that: dovetail groove type wedge 6 coordinates and is arranged in the endoporus of supplemental support cell cube 1, and dovetail groove wedge 6 can left and right movement in supplemental support cell cube 1, bonnet 2 is arranged in the endoporus of supplemental support cell cube 1 one end, pipe joint 3 is arranged on bonnet 2, and be connected with supplemental support cell cube 1, supplemental support cell cube 1 other end installs protective cover 12, pilot bushing 8 is arranged on supplemental support cell cube 1 top, the outer dovetail cooperation of auxiliary support bar 10 bottom is arranged on the interior dovetail groove of dovetail groove type wedge 6, the cylindrical cooperation of auxiliary support bar 10 is arranged on the endoporus of pilot bushing 8, auxiliary support bar 10 relatively pilot bushing 8 can do relative linear motion, bulb support nail 9 is fixedly mounted on auxiliary support bar 10.
2nd O RunddichtringO 5, the 3rd O RunddichtringO 7 are installed in the groove of dovetail groove type wedge 6; One O RunddichtringO 4 is installed in the groove of bonnet 2; Dust ring 11 is installed in the groove of pilot bushing 8.
During work, from hydraulic oil port H logical oil inwards, hydraulic oil drives dovetail groove type wedge 6 to move to the left side, then dovetail groove type wedge 6 drives auxiliary support bar 10 and bulb support nail 9 to move upward top tight workpiece by dovetail inside and outside cooperatively interacting, because now hydraulic oil acts on a very little endless belt, so under the prerequisite guaranteeing to drive dovetail groove type wedge 6, make the strength of bulb support nail 9 top tight workpiece less, workpiece can not be made to produce distortion, and due to wedge and horizontal direction angle β=8 °, for Self-locking angle, so when workpiece carries out adding man-hour, if workpiece is applied to the larger power of bulb support nail 9 one, due to the effect of Self-locking angle, auxiliary support bar 10 also can not produce displacement, guarantee hold out against all the time and support workpiece, prevent the generation of cutting vibrations.After machining, from hydraulic oil port B logical oil inwards,
Hydraulic oil drives dovetail groove type wedge 6 to move to the right, then dovetail groove type wedge 6 is by dovetail inside and outside cooperatively interacting, drive auxiliary support bar 10 and bulb support nail 9 to move downward and leave workpiece, because now hydraulic oil acts on a larger area, so can guarantee that dovetail groove type wedge 6 drives auxiliary support bar 10 to reset.
The utility model integrated level is high, and floor space is little, resets reliable, can guarantee auxiliary support bar positive lock in process, thus ensure stable support workpiece, guarantee not occur the situations such as vibration in process, and then improve machining accuracy.
