Description
Technical field
The utility model relates to a kind of clamping tool for machine work, is specifically related to a kind of connecting rod face miller fixture.
Background technology
Connecting rod be in linkage two ends respectively with initiatively and driven member is hinged moves and the rod member of power to transmit.In reciprocating-piston dynamic power machine and compressor, connect piston and crank with connecting rod.Connecting rod mostly is steel part, and the cross section of its main part mostly is circular or I-shaped, and two ends are porose, and hole, built with bronze bushing or needle bearing, forms hinged for loading pivot pin.Connecting rod is the strength member in the engine such as automobile and boats and ships, and it is connected to piston and bent axle, and its effect is the rotary motion reciprocating motion of piston being changed into bent axle, and the power acted on piston is passed to bent axle with power output.Connecting rod at work, except bearing the pressure of combustion chamber combustion gas generation, also will bear the inertia force of vertical and horizontal.Therefore, connecting rod works under a complicated stress state.It is not only by tension and compression stress, but also the stress by bending of alternation.Because connecting rod needs higher machining accuracy, therefore, need to process two end faces of connecting rod, keep the flatness of two end faces.
Utility model content
The purpose of this utility model is to provide a kind of connecting rod face miller fixture, locates accurately connecting rod, makes can accurately locate when processing end face, prevents when processing because the error of fixture itself causes the accumulation of mismachining tolerance.
For achieving the above object, the technical solution of the utility model is: connecting rod face miller fixture, comprises base, and described base is provided with a fixing fixture block and a floating fixture block, and described fixing fixture block and floating fixture block are positioned at same horizontal plane; Described base is also provided with holder, the passage of level is provided with in described holder, described horizontal channel comprises a helical duct and a floating fixture block passage, in described helical duct, threaded engagement has a screw rod, one end of described screw rod is provided with handwheel, and the other end of described screw rod is rotationally connected floating fixture block; The end face that described fixing fixture block is relative with floating fixture block is respectively equipped with V-arrangement clip slot.
When adopting technique scheme, rotate handwheel, make bolt rotary, under the constraint of helical duct, screw rod drives the fixture block that floats to move in floating fixture block passage.By the V-arrangement clip slot that the end face that fixing fixture block is relative with floating fixture block is arranged respectively, the end of connecting rod is clamped.By this setting, can clamp the non-machined surface of connecting rod, and the clip slot of V-arrangement planar can carry out Complete Bind to connecting rod, improves the precision of processing, prevents the accumulation of mismachining tolerance.
Further, described fixing fixture block is bolted on base, and described horizontal channel is bolted on base.This setting can be convenient to dismantle and change corresponding mechanism, is convenient to maintenance on the one hand and changes, and on the other hand, during connecting rod for processing different size, only can change corresponding mechanism, not need to change whole fixture.
Further, described base is also provided with two vertical positioning sleeves, the cross section of described positioning sleeve is T-shaped, runs through being provided with locating hole in described positioning sleeve, and described V-arrangement clip slot, locating hole are positioned on straight line.Described positioning sleeve can conveniently be positioned by the connecting hole on connecting rod.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model connecting rod face miller fixture embodiment;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Detailed description of the invention
As depicted in figs. 1 and 2, the utility model connecting rod face miller fixture, includes base 7, and base 7 is provided with a fixing fixture block 1 and a floating fixture block 4, and fixing fixture block 1 and floating fixture block 4 are positioned at same horizontal plane; Fixing fixture block 1 is bolted on base 7, and horizontal channel 8 is also bolted on base 7.This setting can be convenient to dismantle and change corresponding mechanism, is convenient to maintenance on the one hand and changes, and on the other hand, during connecting rod 2 for processing different size, only can change corresponding mechanism, not need to change whole fixture.Base 7 is also provided with holder 8, be provided with the passage of level in holder 8, horizontal channel comprises a helical duct and a floating fixture block passage, and in helical duct, threaded engagement has a screw rod 51, one end of screw rod 51 is provided with handwheel 5, and the other end of screw rod 51 is rotationally connected floating fixture block 4; The end face that fixing fixture block 1 is relative with floating fixture block 4 is respectively equipped with V-arrangement clip slot.Base 7 is also provided with two vertical positioning sleeves 3, the cross section of positioning sleeve 3 is T-shaped, and positioning sleeve 3 is arranged in the installing hole 6 on base 7.Run through in positioning sleeve 3 and be provided with locating hole, V-arrangement clip slot, locating hole are positioned on straight line.Positioning sleeve 3 can conveniently be positioned by the connecting hole on connecting rod 2.
In the utility model, rotate handwheel 5, drive screw rod 51 to rotate, under the constraint of helical duct, screw rod 51 drives the fixture block 4 that floats to move in floating fixture block passage.By the V-arrangement clip slot that the end face that fixing fixture block 1 is relative with floating fixture block 4 is arranged respectively, the end of connecting rod 2 is clamped.By this setting, can clamp the non-machined surface of connecting rod 2, and the clip slot of V-arrangement planar can carry out Complete Bind to connecting rod 2, improves the precision of processing, prevents the accumulation of mismachining tolerance.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
