Abstract
The utility model relates to a machining and positioning device for a cylinder bearing of a garden machine. The machining and positioning device comprises a workbench. A supporting seat is arranged at one end of the workbench. A compressing oil cylinder is arranged on the supporting seat. A positioning plate is arranged at the other end of the workbench. A clamping space is formed between the positioning plate and the compressing oil cylinder. A cylinder is located in the clamping space. More than two milling grooves are formed in a clamping surface of the positioning plate. A positioning block is fixed in each milling groove. More than three tungsten steel points are evenly arranged on the clamping surface of the positioning plate. By the adoption of the structure, the cylinder bearing is axially positioned through the positioning blocks in a one-side twice-cut mode; a positioning plane is formed by the tungsten steel points, surface positioning in the prior art is replaced by point positioning, contact is reduced, and machining accuracy is realized; in a machining process, positioning points are unified, requirements of products are met, and the qualified rate of the products is increased; operation time is shortened, clamping is convenient, and machining cost is reduced.
Description
Technical field
The utility model relates to a kind of graden machine cylinder bearing processing and positioning device.
Background technology
In order to reach the required precision of cylinder bearing, the traditional processing technology step of graden machine cylinder is in the prior art: operation one, processing face work and brill flange face; Operation two adopts the plane and two pits locate mode, and compresses work piece; Operation three, machining bearing hole, cylinder cylinder diameter, spark plug face and thread, and then the processing of the bottom outlet tapping of the air inlet face of countercylinder and deflation area and left and right sides face; Operation four is electroplated hone.This technology will cause spiral shell pressure degree to weaken after having electroplated, occur easily in the assembling process breaking in the tooth hole and the situation of sliding tooth, so just its processing technology step is dispatched in the prior art, after the drilling-tapping operation is transferred to plating, yet after electroplating, the flange face hole dimension increases coating, so need to locate with the mode of plane and two pits again, be equivalent to the secondary clamping, can't guarantee the Geometrical Tolerance Principle of being correlated with, just make the deterioration in accuracy of processing; Simultaneously, need two location of contraposition aperture in the clamping process, be inconvenient to proofread and correct, wander off easily, consuming time being unfavorable for enhances productivity, and increased burden to enterprise.
Summary of the invention
The purpose of this utility model is to provide a kind of and improves machining accuracy, is easy to the graden machine cylinder bearing processing and positioning device of clamping.
The utility model adopts following structure, graden machine cylinder bearing processing and positioning device, and it comprises workbench, and an end of described workbench is provided with supporting seat, and supporting seat is provided with compressed oil cylinder; The other end of described workbench is provided with location-plate, described location-plate and compressed oil cylinder form a grasping part, cylinder is arranged in grasping part, the clamping face of described location-plate is provided with plural groove milling, locating piece is fixedly arranged in the described groove milling, evenly be provided with the wolfram steel point more than three on the clamping face of described location-plate.
Described locating piece protrudes from the clamping face of location-plate, and the size of described locating piece is less than or equal to the aperture of cylinder dead eye.
The number of described wolfram steel point is four.
The utility model adopts above structure, make the cylinder bearing axially adopt one side two locate modes of cutting by locating piece, form a plane of orientation by wolfram steel point, change point location into by the location of the face in the conventional art, reduce contact and reach machining accuracy, process is unified anchor point, satisfy product requirement, improved the qualification rate of product, improved the operating time, be convenient to clamping, reduced processing cost.
