Abstract
The invention relates to a crankshaft connecting rod journal jig which comprises a head connecting pad (1), screws (2), a head end jig (3), a head end pressure plate (4), a crankshaft (5), a tail end pressure plate (6), a tail end jig (7) and a tail connecting pad (8), wherein the head connecting pad (1) is connected with a lathe and connected with the head end jig (3) by the screws (2), the front end of the crankshaft (5) is connected with head end jig (3) by the head end pressure plate (4), the tail connecting pad (8) is connected with a lathe tailstock sleeve and connected with tail end jig (7) by the screws (2), and the rear end of the crankshaft (5) is connected with the tail end jig (7) by the tail end pressure plate (6). The machined crankshaft connecting rod journal jigs have consistent quality and dimension and high roughness; the crankshaft connecting rod journals with various sizes can be machined; the jig is convenient to adjust; and the cutter cost is low.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of crank-shaft link neck anchor clamps.
Background technology
Existing S
1-217 crankshaft toothed wheel connecting rod necks, its specification requirement are the necessary consistent size of clamping axle journal, and the cost of charp tool one cover cutter is wanted 164 yuan; And need one of cutter sharpener; Whenever change a kind of different model product and will do eccentric semicircle watt, it is higher to do semicircle watt cost, inconvenience; Shortcoming is to use scope less, conversion product trouble.
Summary of the invention
Technical problem to be solved by this invention provides a kind of crank-shaft link neck anchor clamps; The present invention has practiced thrift the processing cost of operation significantly through transforming anchor clamps, and the surface roughness that processes is good; Consistent size can be processed the big or small crank-shaft link neck of various different models simultaneously.
Technical scheme of the present invention: a kind of crank-shaft link neck anchor clamps, it comprises a terminal pad 1, screw 2; Head end anchor clamps 3, head end pressing plate 4, bent axle 5; Tail end pressing plate 6, tail end anchor clamps 7 and tail terminal pad 8, a terminal pad 1 is connected with lathe; Terminal pad 1 is connected with head end anchor clamps 3 through screw 2, and bent axle 5 front ends pass through head end pressing plate 4 and are connected with head end anchor clamps 3, and tail terminal pad 8 is connected with the tail stock sleeve; Tail terminal pad 8 is connected through screw 2 with tail end anchor clamps 7, and the rear end of bent axle 5 is connected with tail end anchor clamps 7 through tail end pressing plate 6.
The present invention compared with prior art has following beneficial effect: the crank-shaft link neck anchor clamps mass size that the present invention processes is consistent, and roughness is higher; Can process the crank-shaft link neck of various different sizes; Anchor clamps are reconciled convenient; The cost of charp tool is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
1 couple of the present invention makes further detailed description below in conjunction with accompanying drawing: a kind of crank-shaft link neck anchor clamps, and it comprises a terminal pad 1, screw 2; Head end anchor clamps 3, head end pressing plate 4, bent axle 5; Tail end pressing plate 6, tail end anchor clamps 7 and tail terminal pad 8, a terminal pad 1 is connected with lathe; Terminal pad 1 is connected with head end anchor clamps 3 through screw 2, and bent axle 5 front ends pass through head end pressing plate 4 and are connected with head end anchor clamps 3, and tail terminal pad 8 is connected with the tail stock sleeve; Tail terminal pad 8 is connected through screw 2 with tail end anchor clamps 7, and the rear end of bent axle 5 is connected with tail end anchor clamps 7 through tail end pressing plate 6.
The present invention utilizes common 30 lathes, through transforming anchor clamps, makes retaining part depart from lathe spindle and tailstock center, reaches crank-shaft link neck and overlaps machining crankshafts connecting rod neck with lathe spindle tailstock center.Cutter only need machine add left and right sides offset tool and 60 the degree sharp knives each 1,138 yuan in the every cover of cutter head cost can be processed 800 axle journals; Share 0.1725 yuan on each connecting rod neck equally; Practiced thrift the processing cost of this procedure to a great extent, the surface roughness that processes is high, consistent size; Drawing requirement can be satisfied, the big or small crank-shaft link neck of various different models can be processed simultaneously.
