Abstract
The utility model relates to the industry of machinery manufacture, in particular relates to a fixture for manufacturing main pin holes of a fore axis. The fixture comprises a fixture body, a revolution base seat, a fixture base plate, a location clamping mechanism, a central spindle, an upper flange, a cylinder barrel, a piston, a lower flange and a bolt mechanism, wherein the revolution base seat is installed on the fixture body, the cylinder barrel is installed in a center hole of the revolution base seat by the lower flange from the lower part of the revolution base seat, the piston is installed in the cylinder barrel, the fixture base plate is installed at the upper end of the central spindle, a bearing is padded between the fixture base plate and the piston, the central spindle is installed in a center hole of the piston, the bearing is installed at the lower end of the central spindle and then fastened by a nut, the bolt mechanism is installed at the front end of the revolution base seat, and the location clamping mechanism is installed on the upper plane of the fixture base plate. According to the utility model, only one set of fixture is needed, and the manufacture of the main pin holes at two ends of a fore axis can be completed by clamping for once, so that production cost is saved, production efficiency is improved, labor intensity is lowered, and manufacture accuracy is improved.
Description
Technical field
What the present invention relates to is machine industry, is specially processing front-axle pivot hole anchor clamps.
Background technology
The kingpin bore processing request at the two ends of automobile front axle is than higher; Because need two sleeve clamps just can accomplish processing through twice clamping when adopting prior art processing front-axle pivot hole, this just causes production cost to increase, labor strength is big; Production efficiency is low, and machining accuracy also can not get guaranteeing.
Summary of the invention
The purpose of this invention is to provide a kind of anchor clamps of simple, highly-efficient processing automobile front axle two ends kingpin bore, it can position clamping to automobile front axle fast and accurately through easy operation.
Technical solution of the present invention is: processing front-axle pivot hole anchor clamps; Comprise clamp body, rotary table, anchor clamps base plate, positioning and clamping mechanism, mandrel, upper flange, cylinder barrel, piston, lower flange, bolt mechanism, rotary table is installed on the clamp body, and lower flange below is installed in cylinder barrel in the centre bore of rotary table from rotary table; Piston is installed in the cylinder barrel; The anchor clamps base plate is installed in the mandrel upper end and is lined with bearing with piston is middle, and mandrel is installed in the centre bore of piston, and nut check is used after installing bearing in the lower end; Bolt mechanism is contained in the front end of rotary table, and positioning and clamping mechanism is installed in the last plane of anchor clamps base plate;
Advantage of the present invention is following: only need a sleeve clamp, a clamping just can be accomplished the processing of front axle two ends kingpin bore, has practiced thrift production cost, has improved production efficiency, has reduced labor strength, has improved machining accuracy.
Description of drawings
Below in conjunction with accompanying drawing and enforcement principle the present invention is further specified.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Shown in Fig. 1, Fig. 2; Processing front-axle pivot hole anchor clamps; Comprise clamp body (1), rotary table (2), anchor clamps base plate (3), positioning and clamping mechanism (4), mandrel (5), upper flange (6), cylinder barrel (7), piston (8), lower flange (9), bolt mechanism (10); Rotary table (2) is installed on the clamp body (1); Lower flange (9) below is installed in cylinder barrel (7) in the centre bore of rotary table (2) from rotary table (2), and piston (8) is installed in the cylinder barrel (7), and anchor clamps base plate (3) is installed in mandrel (5) upper end and the middle bearing that is lined with of piston (8); Mandrel (5) is installed in the centre bore of piston (8); Nut check is used after installing bearing in the lower end, and bolt mechanism (10) is contained in the front end of rotary table (2), and positioning and clamping mechanism (4) is installed in the last plane of anchor clamps base plate (3).
Concrete operation principle: anchor clamps base plate (3) is installed on the mandrel (5), is fitted together with piston (8), when fluid gets into the pressure chamber of piston (8), lower flange (9) and cylinder barrel (7) composition; Promote anchor clamps base plates (3) and upwards lift, at this moment, under the bearing effect of bearing; Can promote anchor clamps base plate (3) is the center rotation with mandrel (5), and after rotation put in place, fluid got into the pressure chamber that piston (8), upper flange (6) and cylinder barrel (7) are formed; Promoting anchor clamps base plates (3) descends; Bolt mechanism (10) inserts alignment pin in the pin-and-hole of anchor clamps base plate (3) one ends, and after anchor clamps base plate (3) decline put in place, piston (8) was locked under the effect of oil pressure; Positioning and clamping mechanism (4) is the center with mandrel (5); Symmetry be installed in anchor clamps base plate (3) above, through the adjustment positioning and clamping mechanism (4) centre-to-centre spacing and locating piece, can adapt to the processing in different cultivars front-axle pivot hole.
