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 dual mode, first kind of way is to adopt Digit Control Machine Tool, program entry after before processing, will programming, lathe is carried out processing action according to program during processing, turning goes out the 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 the calibration, form the eccentric excircle face, the calibration positioning step that a workpiece will be arranged like this, operation is trouble comparatively, and production efficiency is lower

Summary of the invention

The frock clamp that the purpose of this invention is to provide the eccentric excircle face that is used for processing work that cost is lower, efficient 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 the described support, setting is passed in the connecting rod in the described pair of brackets, be set in the first gear that plays the driving effect on the described connecting rod in the arranged outside of described support, described wabbler mechanism comprises the frame that plays supporting function that the 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 the 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, the described first top body is passed in the 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 contact is on the surface of described limiting plate, in described frame side bolt is set, one end is set is fixedly connected on elastic component on the described fixed bar, the other end of described elastic component can be hooked on the 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: the connecting rod that is fixed on the support of base passes the bottom of frame, frame is connected on the base, be set in the first gear on the connecting rod in the arranged outside of support, be oppositely arranged first top in the groove inboard of frame, second is top, the first top body passes a sidewall of frame, be set in first the second gear on top in the sidewall arranged outside, the first gear, the second gear is meshed, side at the base horizontal direction arranges limiting plate, be connected with the fixed bar of an end of elastic component, be set in the first eccentric wheel on top in the inside sidewalls setting, eccentric wheel is that periphery contacts with limiting plate, during processing work, the other end of elastic component is connected on the bolt of frame, the first gear driven the second gear rotates, elastic component pulling frame, guarantee that eccentric periphery contacts with limiting plate all the time, frame swings in a lateral direction when then processing, turning goes out the eccentric excircle face of workpiece, processing cost is low like this, and working (machining) efficiency is high.

Description of 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.

The specific embodiment:

Referring to shown in Figure 1, pair of brackets is set along the longitudinal direction such 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 the connecting rod 3 in the arranged outside of support 2, the first gear 4 can play the driving effect to frock clamp of the present invention when processing work, the frame 5 that the bottom is passed by connecting rod 3 is set, the top of frame 5 has groove, groove is connected with the outside in a lateral direction, in groove, be provided for along the longitudinal direction first top 6 of fixation workpiece, second top 7, during 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 the 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, inboard at this sidewall arranges the eccentric wheel 9 that is set on first top 6, during the 11 driven rotation of the second gear, 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, in frame 5 bolt 12 is set, fixed bar 10, bolt 12 lays respectively at the both sides of frame 5 in a lateral direction, elastic component 13 1 ends are connected on the fixed bar 10, during processing work, the other end of elastic component 13 is connected on the bolt 12.

Referring to shown in Figure 2, during 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 waving in a lateral direction, is fixed on then that the processed periphery shape with eccentric wheel 9 of workpiece between first top 6, second top 7 is identical, the eccentric excircle face of big or small bi-directional scaling.
