Description

A kind of automobile transmission gear sharpener

Technical field

This utility model is related to Gear Processing field, and in particular to a kind of automobile transmission gear sharpener.

Background technology

When automobile transmission gear is manufactured, needs are first cut into pieces the blank of gear-like according to the height of gear, then right These blanks in section shape carry out turning, and gear is made through programs such as polishing, polishings again after turning.Gear polishing is mainly Two end faces of the gear teeth and gear to gear are ground, and go flash removed to make the surface of gear smooth, and traditional polishing is behaviour Author takes emery wheel manual grinding, plus man-hour to waste time and energy, and output efficiency is relatively low；Other modes, for example using emery wheel to rotation Gear is polished, and makes emery wheel polish the gear teeth successively, and gear is transferred to into next grinding mechanism to gear after having polished Two end faces are ground, though comparing for manpower manual operations, crudy and working (machining) efficiency are improved, to gear elder generation Grinding worm is regrinded and cuts end face, and inherently the time is longer to carry out being distributed the mode of processing, and needs to shift gear, and what is made is whole The individual grinding time is longer, and efficiency is equally more low.

Utility model content

This utility model purpose is to provide a kind of automobile transmission gear sharpener, is solved in prior art in gear grinding The problem of inefficiency when cutting.

This utility model is achieved through the following technical solutions：

A kind of automobile transmission gear sharpener, including frame, connecting rod, main bistrique, two pressing plates and it is arranged on frame The motor of side, main bistrique is arranged in frame by axis of rotation, motor output end through frame side wall after with rotating shaft end Portion connects, and in the frame central shaft is fixed with, and cannelure, multiple cushion blocks and multiple side grinding heads are provided with the central shaft Staggeredly be set in cannelure, be provided with screw thread on the outer wall of cannelure two ends end, two nuts be set on cannelure and It is engaged with screw thread, multiple screws being distributed side by side is provided with the both sides inwall of frame, screw is located at the central shaft and rotating shaft Between and exist together on a horizontal line with both, pressing plate is fixed in frame by the cooperation of screw and screw, the connecting rod Two ends are rotatably arranged on respectively on pressing plate, and the side grinding head is made up of the brush board of the connecting plate and circle that are connected with each other, central shaft Through connecting plate, adjustment hole is provided with the brush board, the connecting rod runs through the adjustment hole, and in two side walls of the brush board Steel brush hair is provided with, multiple gears are set on central shaft, and single gear is located between two adjacent brush boards；The tune Knothole is round rectangle hole, and resilient rubber blanket is set on the extreme position at the adjustment hole two ends, the rubber blanket Section is circular arc.For in prior art, the polishing of gear, polishing efficiency are low, and the production cost that consumes is higher asks Topic, inventor is by the improvement to structure of polishing so that multiple gears can be polished simultaneously, and can also be to the tooth of gear Face and two end faces are processed by shot blasting simultaneously, shorten the polishing man-hour of gear, while grinding efficiency is improved, also protect The identical degree of multiple gears processed in the lump is demonstrate,proved.

During concrete operations, multiple gears are sequentially sleeved on connecting rod, and ensure that single gear is located at two adjacent sides Between bistrique, be then arranged pressing plate respectively at the two ends of connecting rod so that connecting rod can freely be rotated on pressing plate, central shaft with turn On the line segment that axle is constituted, multiple screws are distributed side by side, from the screw station of correct position, are fixed on pressing plate by screw On two side walls of frame, because central shaft is fixed so that the position of side grinding head is fixed, and in installation and debugging, in side grinding head Brush board part on be provided with adjustment hole, connecting rod can be moved radially in adjustment hole, to ensure the multiple gears on connecting rod The flank of tooth can be contacted with main bistrique；Steel bristle brush is provided with two surfaces up and down of circular brush board, by rotating nut so that many Individual side grinding head by the two ends of central shaft, thereto draw close by portion, while the steel brush hair on brush board and the end contact of gear, start electricity Machine, main bistrique drive pinion rotation while, steel brush hair also begins to polish the end face of gear, i.e., by main bistrique with Side grinding head cooperates so that the flank of tooth and end face of multiple gears carries out sanding and polishing simultaneously, substantially increases gear Treatment effeciency.Wherein, adjustment hole is round rectangle hole, and is provided with rubber blanket on two extreme positions of adjustment hole so that When the extreme position of adjustment hole is moved to, connecting rod outer wall is directly contacted connecting rod with rubber blanket, and rubber blanket can be to the motion of connecting rod Trend carries out the stop buffering of flexibility, to avoid relative wear between connecting rod and adjustment hole, extends the use longevity of sharpener Life.

The steel brush fleece is divided into the cleaning unit of two minor arc shapes, and two cleaning units along brush board side wall The center of circle is symmetrical.On two end faces of gear, the surface area shared by gear shaft holes is removed, the steel brush fleece is divided into two The cleaning unit of individual minor arc shape, and two cleaning units are symmetrical along the center of circle of brush board side wall, because gear is by main mill Head persistently drives so that Steel bristle brush is persistently polished the end face of gear, and Steel bristle brush is divided into the clear of two minor arc shapes Reason unit, i.e. cleaning unit remains at a suitable scope with the contact area of gear face, to ensure gear end Each local in face can only be polished twice when rotation one is enclosed, i.e. once thick polishing and once smart polishing, in the tooth for ensureing gear On the premise of the grinding and polishing optical processing efficiency of face and end face, it is to avoid defect ware occurs in gear, the scrappage of Gear Processing is reduced.

The cushion block is elastic block rubber.Preferably, the cushion block selects elastic block rubber, i.e. cushion block to possess certain Elastic deformation ability, in tightening nut, forms mutually extruding between multiple connecting plates, returned by the deformation and deformation of cushion block It is multiple, to avoid two acting surfaces relative on adjacent two brush board from forming excessive compression to the end face of gear, prevent in gear Steel bristle brush is excessively ground to gear face during rotation.

This utility model compared with prior art, has the following advantages and advantages：

1st, this utility model is by the improvement to structure of polishing so that multiple gears can be polished simultaneously, and also The flank of tooth of gear and two end faces can be simultaneously processed by shot blasting, shorten the polishing man-hour of gear, improve polishing effect While rate, it is ensured that the identical degree of multiple gears processed in the lump；

2nd, cushion block selects elastic block rubber, i.e. cushion block to possess certain elastic deformation ability in this utility model, is screwing During nut, mutually extruding, the deformation and deformation recovery by cushion block, to avoid adjacent two are formed between multiple connecting plates Two acting surfaces relative on brush board form excessive compression to the end face of gear, prevent in pinion rotation Steel bristle brush to gear end Face is excessively ground.
