Abstract

The invention discloses a fixture for machining the eccentric outer circular surfaces of workpieces. A rack is connected to a base through a connecting rod, one side of the base is provided with a first gear sleeved on the connecting rod, a first centre and a second centre which are oppositely arranged and used for clamping workpieces are arranged on the rack, the side face of the rack is provided with a bolt, a second gear and an eccentric wheel are respectively sleeved on the first centre, the second gear is meshed with a first gear, the transverse side face of the top of the rack is provided with a limiting plate and a fixed pole, one end of an elastic piece is connected to the fixed pole, the other end of the elastic piece is connected to the bolt, and the outer circular surface of the eccentric wheel is contacted with the limiting plate. In the process of machining a workpiece, under the action of contacting, the rack swings in the transverse direction, so that the eccentric outer circular surface of the workpiece can be machined conveniently, in such a way, the machining cost is low, and the machining efficiency is high.

Description

A kind of frock clamp of the eccentric excircle face for processing work

Technical field

the present invention relates to a kind of frock clamp of the eccentric excircle face for processing work.

Background technology

the processing of the eccentric excircle face of existing workpiece, can adopt in two ways, first kind of way is to adopt Digit Control Machine Tool, before processing by programming after program entry, when processing, lathe is carried out processing action according to program, turning goes out eccentric excircle face, the cost of equipment is higher like this, the second way is to adopt four jiaos of chucks, and workpiece is contained on four jiaos of chucks, carries out machining after calibration, form eccentric excircle face, will have like this calibration positioning step of a workpiece, operation is trouble comparatively, and production efficiency is lower.

Summary of the invention

the object of this invention is to provide the frock clamp of the eccentric excircle face for processing work that cost is lower, efficiency is higher.

for achieving the above object, the invention provides a kind of frock clamp of the eccentric excircle face for processing work, described frock clamp comprises base, be oppositely arranged on along the longitudinal direction the pair of brackets of described base top, be connected to the wabbler mechanism on described support, setting is passed in the connecting rod in described pair of brackets, be set in the first gear that plays driving effect on described connecting rod in the arranged outside of described support, described wabbler mechanism comprises the frame that plays supporting function that bottom is passed by described connecting rod, be arranged on the limiting plate of horizontal direction one side at the top of described base, fixed bar, the top of described frame has groove, described groove is connected with outside in a lateral direction, on the medial surface of described groove, be oppositely arranged along the longitudinal direction first top for fixing described workpiece, second is top, described the first top body is passed in a sidewall of described frame along the longitudinal direction, setting is set in described first the second gear on top, described the first gear, described the second gear is meshed, arrange described groove madial wall be set in the described first eccentric wheel on top, described eccentric periphery contacts on the surface of described limiting plate, in described frame side, bolt is set, one end is set and is fixedly connected on the elastic component on described fixed bar, the other end of described elastic component can be hooked on described bolt.

preferably, described fixed bar, described bolt lay respectively at the both sides of described frame in a lateral direction.

because technique scheme is used, the present invention compared with prior art has following advantages and effect: be fixed on connecting rod on the support of the base bottom through frame, frame is connected on base, be set in the first gear on connecting rod in the arranged outside of support, be oppositely arranged first top in the groove inner side of frame, second is top, the first top body passes a sidewall of frame, be set in first the second gear on top in sidewall arranged outside, the first gear, the second gear is meshed, a side at base horizontal direction arranges limiting plate, be connected with the fixed bar of one end of elastic component, be set in the first eccentric wheel on top in inside sidewalls setting, eccentric wheel is that periphery contacts with limiting plate, when processing work, the other end of elastic component is connected on the bolt of frame, first gear driven the second gear rotates, elastic component pulls frame, guarantee that eccentric periphery contacts with limiting plate all the time, while processing, frame swings in a lateral direction, turning goes out the eccentric excircle face of workpiece, processing cost is low like this, working (machining) efficiency is high.

brief description of the drawings:

accompanying drawing 1 is looked schematic diagram for master of the present invention;

accompanying drawing 2 is schematic top plan view of the present invention.

detailed description of the invention:

shown in Figure 1, pair of brackets is set along the longitudinal direction as 2 at the top of base 1, connecting rod 3 is passed in pair of brackets as in 2, be set in the first gear 4 on connecting rod 3 in the arranged outside of support 2, the first gear 4 can play driving effect to frock clamp of the present invention in the time of processing work, the frame 5 that bottom is passed by connecting rod 3 is set, the top of frame 5 has groove, groove is connected with outside in a lateral direction, in groove, be provided for along the longitudinal direction first top 6 of fixation workpiece, second top 7, when processing work, first top 6, second top 7 is inserted in respectively in the locating hole at workpiece two ends, first top 6 body is passed in a sidewall of frame 2 along the longitudinal direction, be set in the second gear 11 on first top 6 in the arranged outside of this sidewall, the first gear 4, the second gear 11 is intermeshing, inner side at this sidewall arranges the eccentric wheel 9 being set on first top 6, when the second gear 11 is driven and is rotated, can drive first top 6 so that band movable eccentric wheel 9 rotate, press close to frame 5 in a side of base 1 top cross direction limiting plate 8 is set, fixed bar 10, bolt 12 is set in frame 5, fixed bar 10, bolt 12 lays respectively at the both sides of frame 5 in a lateral direction, elastic component 13 one end are connected on fixed bar 10, when processing work, the other end of elastic component 13 is connected on bolt 12.

shown in Figure 2, when processing work, under the effect of elastic component 13, the periphery of eccentric wheel 9 contacts with limiting plate 8 all the time, under the effect of this contact, first top 6 constantly changes with the distance of limiting plate 8, and frame 5 realizes and waving in a lateral direction, is fixed on the eccentric excircle face of processed, the big or small bi-directional scaling identical with the periphery shape of eccentric wheel 9 of workpiece first top 6, between second top 7.
