Abstract

The utility model belongs to machining technological equipment, and particularly relates to a positioning clamp special for processing a crankshaft. The positioning clamp comprises a clamp body (3), wherein a clamping hole (3-1) is formed at the lower end of the clamp body (3); a locking bolt (1) is arranged at an opening part of the lower end of the clamping hole (3-1); two auxiliary locking bolts (2) are arranged on each of outer edges on two sides of the clamp body (3) along the horizontal center line of the clamping hole (3-1); and a plurality of crankshaft positioning center holes (3-2) are formed in the clamp body (3) corresponding to an extension line of the vertical center line of the clamping hole (3-1) according to the offset. The positioning clamp special for processing the crankshaft is stable in processing quality, high in production efficiency, low in material consumption and low in production cost, reduces the labor intensity of workers, and meets processing requirements with various offsets.

Description

Bent axle is processed special-purpose positioning fixture
Technical field
The utility model belongs to the mechanical processing technique equipment, and particularly a kind of bent axle is processed special-purpose positioning fixture.
Background technology
The processing of existing crankshaft eccentric crank all is to rely on bent axle special purpose machine tool or engine lathe to accomplish, and special purpose lathe costs an arm and a leg, and the bent axle manufacturing cost is high; Adding man-hour with engine lathe, must be benchmark with the crankshaft axis at crankshaft two end, gets crankshaft axis centre of location hole in advance according to offset; Blank must be diameter greater than the bar of offset more than two times, the metal cutting amount is big, stock utilization is low; Consume more man-hour; Crudy is also stable inadequately, and labor strength is big, and production efficiency is low.If adopt the processing of moulding bent axle forge piece blank, can greatly reduce material consumption, alleviate labor strength, but do not have special fixture to be difficult to accomplish above-mentioned processing.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, steady quality, and the bent axle that production efficiency is high is processed special-purpose positioning fixture.
The technical scheme that the utility model technical solution problem adopts is: bent axle is processed special-purpose positioning fixture and is comprised clamp body; Being characterized in that the clamp body lower end is provided with clamps the hole; Clamp lower ending opening place, hole clamping screw is housed; Along clamping on the outer rim of hole horizontal center line clamp body both sides two auxiliary clamping screws are housed respectively, clamp on the corresponding clamp body of the vertical center line extended line in hole and be provided with a plurality of bent axle centres of location hole according to offset.
The beneficial effect of the utility model is: bent axle is processed special-purpose positioning fixture stable processing quality, and production efficiency is high, and material consumption is few, and production cost is low, alleviates labor strength, satisfies the process requirements of multiple offset.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is that bent axle is processed special-purpose positioning fixture structure and figure cuts open in office.
Fig. 2 is the left side view of Fig. 1.
Among the figure, the 1-clamping screw; 2-assists clamping screw; The 3-clamp body; 3-1-clamps the hole; 3-2-bent axle centre of location hole; The 4-workpiece.
The specific embodiment
Embodiment, with reference to accompanying drawing 1,2, clamp body 3 lower ends that bent axle is processed special-purpose positioning fixture are provided with and clamp hole 3-1, clamp 3-1 lower ending opening place, hole clamping screw 1 is housed.Along clamping on the 3-1 horizontal center line clamp body 3 both sides outer rims of hole two auxiliary clamping screws 2 are housed respectively, clamp on the corresponding clamp body 3 of the vertical center line extended line of hole 3-1 and be provided with five bent axle centre of location hole 3-2 according to offset.
The method for using that bent axle is processed special-purpose positioning fixture is: the utility model must be that two clamp bodies 3 of symmetry use simultaneously; At first clamp body 3 is set on the workpiece 4 left and right two ends spindle noses, is locked, on lathe spindle hole and tailstock, install top respectively with clamping screw 1 and auxiliary clamping screw 2; Top the top respectively according to rightabout on lathe spindle hole and the tailstock is stuck on the clamp body 3 corresponding bent axle centre of location hole 3-2; After confirming that selected bent axle centre of location hole 3-2 is errorless, with chuck jaw chucking anchor clamps 3, the locking tailstock can be implemented processing; If needed, balancing weight can be installed on chuck.
