Abstract

The invention discloses a production tooling for an iron ball element of a centrifugal machine bearing seat. The production tooling comprises a clamp body used for fixing the iron ball element, wherein the middle part of the clamp body is provided with an expansion positioning pin used for fixing a hollow cylindrical through hole of the iron ball element, and a positioning pin correspondingly connected with a kidney-shaped groove of the iron ball element is also arranged on the clamp body. Through the arrangements of the expansion positioning pin, the positioning surface and the positioning pin on the surface of the clamp body, the goal of precisely positioning workpieces is reached, a special-shaped conical pin and a special-shaped cone which are arranged on the surface of the clamp body are in interference fit, so the positioning of the expansion positioning pin is more precise, and the service life is prolonged. The production tooling has the advantages that a plurality of positioning surfaces are designed, and the iron ball element and the production tooling for the iron ball element of the centrifugal machine bearing seat keep good levelness during clamping.

This shows that above-mentioned existing processing mode obviously still has inconvenience and defective, and demands urgently further improving in the use.In order to solve the problem that existing processing mode exists; Relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly; But do not see always that for a long time suitable design is developed completion; And common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because the defective that above-mentioned existing processing mode exists; The inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge; And cooperate the utilization of studying the science, actively study innovation, in the hope of founding a kind of centrifuge bearing block magnesium iron spare production frock of new structure; Can improve general existing processing mode, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, found out the present invention of true tool practical value finally.
Summary of the invention
Main purpose of the present invention is; Overcome the defective that existing processing mode exists; And a kind of centrifuge bearing block magnesium iron spare production frock of new structure, technical problem to be solved are provided is that its positioning accuracy is improved, and prolong service life; Thereby be suitable for practicality more, and have the value on the industry.
The object of the invention and solve its technical problem and adopt following technical scheme to realize.Centrifuge bearing block magnesium iron spare production frock according to the present invention's proposition; Comprise the chuck body that is used for fixing magnesium iron spare; The middle part of said chuck body is provided with the expansion alignment pin that is used for fixing magnesium iron spare hollow circuit cylinder through hole, also is provided with the alignment pin with the corresponding connection of kidney slot of magnesium iron spare on the said chuck body.
Aforesaid centrifuge bearing block magnesium iron spare production frock, wherein, said expansion alignment pin comprises special-shaped taper bolt and the special-shaped cone interference fit composition that is arranged on this chuck body.
Aforesaid centrifuge bearing block magnesium iron spare production frock, wherein, the bottom of said special-shaped cone is cylindrical, top is conical composite construction, evenly is provided with groove on the said special-shaped cone periphery.
Aforesaid centrifuge bearing block magnesium iron spare production frock, wherein, the bottom of said special-shaped taper bolt is the cylinder bodily form, top is the composite construction of cone shape.
Aforesaid centrifuge bearing block magnesium iron spare production frock, wherein, on said chuck body around this expansion alignment pin be provided with a plurality of with should be fixedly the locating surface that is fastened of magnesium iron spare.
Aforesaid centrifuge bearing block magnesium iron spare production frock, wherein, said locating surface is three.
By technique scheme, centrifuge bearing block magnesium iron spare production frock of the present invention has advantage at least:
Through expansion alignment pin, locating surface and alignment pin being set on the chuck body surface; Reach the pinpoint purpose of workpiece, be arranged on lip-deep special-shaped cone of said chuck body and special-shaped taper bolt interference fit, make expansion alignment pin more accurate positioning; Prolong its service life; The design of a plurality of locating surfaces of the present invention when clamping, makes magnesium iron spare and centrifuge bearing block magnesium iron spare production frock keep good levelness.
In sum, the centrifuge bearing block magnesium iron spare production frock of special construction of the present invention, positioning accuracy improves, and prolong service life.It has above-mentioned many advantages and practical value, and in like product, does not see have similar structural design to publish or use and really belong to innovation, no matter it structurally or bigger improvement all arranged on the function; Have large improvement technically; And produced handy and practical effect, and more existing processing mode has the multinomial effect of enhancement, thus be suitable for practicality more; And have the extensive value of industry, really be a novelty, progress, practical new design.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.
