Abstract
The invention relates to a balance shaft machining tool for an automobile balanced suspension. The balance shaft machining tool mainly comprises a working platform, a mandrel, a bottom plate, a support post and positioning posts, wherein the working platform is arranged at the upper end of the bottom plate, the cross section of the bottom plate is circular, and the mandrel, the support post and the positioning posts are arranged at the upper end of the working platform; the mandrel is arranged in the center of the working platform, and the support post is arranged at the front end of the working platform; two positioning posts are obliquely arranged on both sides of the tail end of the working platform respectively; a cavity into a workpiece projection can extend is formed at a corresponding position between the mandrel and each positioning post, and the cross section of the cavity is rectangular. The balance shaft machining tool has the advantages that the center of a workpiece is sleeved on the mandrel for fixing, the tail end of the workpiece extends into a gap between adjacent holes of the workpiece via the two positioning posts, and the positioning posts and the mandrel are arranged in a triangular form, thereby allowing the workpiece to be well fixed by using the characteristic of high stability of a triangle.
Description
Technical field
The present invention relates to a kind of processing tool, a kind of trunnion shaft of balancing suspension detects frock specifically.
Background technology
If two vehicle bridge (as the jackshaft of three-axle vehicle and back axle) are contained in to the two ends of balancing pole, and balancing pole middle part is connected as hinge type with vehicle frame, a vehicle bridge is raised and will another vehicle bridge be reduced.And because balancing pole two arms are isometric, the vertical load of two vehicle bridge under any circumstance all equates, can not produce the situation of indivedual wheel hangings.In this can assurance, suspension that back axle analysis of wheel vertical load is equal, be called equalizing type of suspension.
At present, in the manufacturing process of trunnion shaft, trunnion shaft is added to man-hour, after balance location need to being fixed, carry out again, traditional method is to be all fixedly connected with by screw rod, after completing processing, remove with spanner, installation and removal all needs to consume long time so again, and operating efficiency is lower.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of can be good at the balanceable shaft processing frock of the fixing balancing suspension of trunnion shaft.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of trunnion shaft of balancing suspension detects frock, and its innovative point is: mainly comprise workbench, mandrel, base plate, support column and locating dowel;
Described workbench is arranged on the upper end of base plate, and the rounded shape of cross section of base plate, is provided with mandrel, support column and locating dowel in the upper end of workbench;
Described mandrel is arranged on the center of workbench, mandrel is stepped, described mandrel is mainly divided into the first ladder section, second-order bench, the 3rd ladder section and quadravalence bench, the first ladder section is for embedding section, on workbench, have the embedded hole matching with the first ladder section, the diameter of second-order bench, the 3rd ladder section and quadravalence bench reduces successively, the curved shape in junction of second-order bench and the 3rd ladder section;
Described support column is arranged on the front end of workbench, the rectangular shape of cross section of support column, in the upper end of support column, have the rectangular recess that an appearance workpiece is put, two drift angles of the bottom of described rectangular recess are arc chord angle, and the center line of described support column is through the axle center of mandrel;
Described locating dowel one has two, be inclined at respectively the both sides of workbench tail end, locating dowel mainly comprises bottom fixed part and top movable portion, movable part is connected with fixed part by screw rod, screw rod is fixed by the bolt tightening that is positioned at movable part upper end, and the spacing of two adjacent holes of the width of described movable part and workpiece tail end matches;
Relevant position between described mandrel and locating dowel has the cavity that an appearance workpiece projection stretches into, the rectangular shape of cross section of cavity, and the center line of cavity and the center line of support column overlap, and in described cavity, can embed corresponding back-up block.
The invention has the advantages that: the center of workpiece is sleeved on mandrel place and is fixed, the tail end of workpiece stretches into by two locating dowels in the gap of adjacent holes of workpiece and is fixed, two locating dowels and mandrel are triangle and arrange, utilize the feature of triangle good stability, make workpiece can be good at fixing, putting of workpiece is convenient in the setting of cavity, support column; When workpiece needs reverse side to place, can in cavity, put a back-up block, facilitate the placement of workpiece.
