Description

A kind of automobile inner bearing adjustment pad leveling mold
Technical field
The utility model belongs to machining equipment field, relates to a kind of automobile inner bearing adjustment pad leveling mold.
Background technology
Inner bearing adjustment pad is arranged on main speed reducer of rear axle shell inside cavity, and Main Function is the rigging position for adjusting driving gear inner bearing, with fastening driving gear, thus makes automobile keep driving force even, stable when transmission.
The mode of production that inner bearing adjusts pad traditional is that point four procedures are processed, it first adopts single-point plate shearing machine to implement operation one blanking processing, then single-point open type steam-operating forcing press is adopted to implement operation two blankings-punching processing, then adopt single-point open type steam-operating forcing press to implement operation three and flatten processing, finally adopt surface grinding machine to implement operation four grinding.Operation three flattens processing and adopts the mould of rigid structure to be delivered on workpiece by the pressure of forcing press, makes it the object reaching leveling.Although leveling mold is through high-precision grinding, because the upper and lower table plane of lathe exists certain parallelism error, workpiece is difficult to the effect reaching leveling.Adjust the pad depth of parallelism at 0.2mm with the inner bearing of rigid structure die reshaping, follow-up needs increase by one surface grinding machine grinding, and the workpiece upper and lower faces depth of parallelism just can reach 0.02 mm of product design requirement.
What the utility model existed based on production technology in prior art just can optimization consider, a kind of band of design cushion type self-adjusting inner bearing adjustment pad leveling mold, blank flattening course is stablized, ensure that the upper and lower faces depth of parallelism of inner bearing adjustment pad is stable and face shaping is regular, the leveling mold producing inner bearing adjustment pad can be met like this by design is a kind of, the quality stability of improving product, just seems very necessary.
Utility model content
The purpose of this utility model is the deficiency optimizing existing production technology, adapts to reality need, provides a kind of automobile inner bearing to adjust pad leveling mold.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is: a kind of automobile inner bearing adjustment pad leveling mold, comprise patrix and counterdie, described patrix comprises the die shank, cope match-plate pattern, upper padding plate and the leveling patrix that are fastenedly connected successively from top to bottom, described counterdie comprises the leveling counterdie and lower bolster that are fastenedly connected successively from top to bottom, between described upper padding plate and leveling patrix, be provided with powerful rubber, be provided with one piece of location-plate at the upper surface of described leveling counterdie.
Described location-plate is semi-annular shape, and location-plate thickness is less than the thickness of workpiece, and the inside arc of location-plate is in the face of Workpiece fixing.
The beneficial effects of the utility model are:
1. band cushion type automatic adjustment punch structure inner bearing adjustment pad leveling mold of the present utility model, by installing the powerful rubber of lastblock additional among mould upper padding plate with the interlayer of leveling patrix, make it upper and lower mould automatically eliminates the upper and lower table plane existence of lathe in the process of exerting pressure parallelism error by the elastic force of rubber, improve the leveling effect of workpiece, the locate mode of semicircle ring type improves the positioning precision of workpiece blank, blank flattening course is stablized, ensures that the upper and lower faces depth of parallelism of inner bearing adjustment pad is stable and face shaping is regular.
2. flatten operation together with leveling being become with the optimization of grinding two procedures, promote productive temp, strengthen production capacity, reduce production cost.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1-Fig. 4.
A kind of automobile inner bearing adjustment pad leveling mold, comprise patrix and counterdie, described patrix comprises the die shank 1 be fastenedly connected successively from top to bottom, cope match-plate pattern 2, upper padding plate 4 and leveling patrix 7, die shank and cope match-plate pattern are interference fit, upper padding plate is arranged on the below of cope match-plate pattern by bolt and alignment pin, leveling patrix is bolted connection the below in upper padding plate, described counterdie comprises the leveling counterdie 10 and lower bolster 11 that are fastenedly connected successively from top to bottom, powerful rubber 5 is provided with between described upper padding plate 4 and leveling patrix 7, powerful rubber 5 is bolted connection the centre in upper padding plate 4 and leveling patrix 7, one piece of location-plate 9 is provided with on the upper surface upper left side of described leveling counterdie 10.
Described location-plate 9 is semi-annular shape, and location-plate 9 thickness is less than the thickness of workpiece, and the inside arc of location-plate 9 is in the face of Workpiece fixing.
Between described patrix and counterdie, be provided with guide pillar guide sleeve structure, described guide pin bushing 3 is connected with cope match-plate pattern 2 by interference fit, and described guide pillar 6 is connected with lower bolster 11 by interference fit.
The operation principle of utility model is summarized as follows:
Driving gear inner bearing adjustment pad in such Jiangling NHR light truck-type rear-end gear reduction assembly is made up through punch process of the 08II steel band that 3.0 mm are thick, just can be used for the processing of leveling mold after blanking procedure, blanking-punching operation:
The first step, by automobile inner bearing adjustment pad leveling mold of the present utility model, is arranged on single-point open type steam-operating 100T forcing press.
Second step, as shown in Figure 2, is placed on the inner bearing adjustment pad 8 after blanking-punching operation above leveling counterdie 10 with long-armed tweezers, and inner bearing adjustment pad 8 is placed in the semicircular ring inner chamber of location-plate 9.
3rd step, start forcing press and punch process is carried out to inner bearing adjusting pad sheet 8, on lathe, workbench and leveling patrix 7 move downward, when flattening patrix 7 lower plane and inner bearing and adjusting that on pad 8, plane just contacts, there is compression and automatically adjust local thickness thus by lathe in powerful rubber 5, the parallelism error that lower table plane exists is eliminated, because location-plate 9 thickness is less than the thickness of workpiece, therefore, until workbench runs to bottom dead centre on lathe, leveling is completed under making inner bearing adjust the effect of pad 8 between leveling patrix 7 and leveling counterdie 10, reach external diameter φ 88 ± 0.2mm, internal diameter φ 69.5 ± 0.1mm, on, the lower two sides depth of parallelism 0.02 mm, after leveling, the structure of workpiece is as Fig. 3, shown in Fig. 4.
4th step, forcing press upper table face, leveling patrix 7 and powerful rubber 5 return.
5th step, takes out the inner bearing adjustment pad 8 through leveling processing with long-armed tweezers, and loads in body feed tank from the inner chamber of location-plate 9.
The inner bearing adjustment pad appearance and size adopting automobile inner bearing of the present utility model to adjust the making of pad leveling mold is stabilized in external diameter φ 88.12mm, internal diameter φ 69.44mm, the upper and lower faces depth of parallelism 0.02 mm, the uniformity of monnolithic case is regular, and the sustainable stable holes aperture of guaranteeing inner bearing adjustment pad profile and the upper and lower faces depth of parallelism reach the designing requirement of product drawing.While improving the quality of products, also improve production capacity, driving gear inner bearing in Jiangling NHR light truck-type rear-end gear reduction assembly adjustment pad production process is flattened by original operation three, the optimization of operation four grinding twice becomes present operation three and flatten together.Single products split run production capacity is promoted to 27350 by 760, and split run production capacity improves nearly 35 times.
