Description
Technical field
The present invention relates to a kind of clamping device, specifically a kind of eccentric wheel clamping device.
Background technology
We know that in the manufacturing of bent axle, some processing and making process must clamp bent axle, so that carry out process operation.For example main bearing journal and connecting rod neck are bored oilhole, its processing needs on two radial drilling machines, respectively to join respectively a cover boring grab branch two procedures and accomplishes.One procedure is bored the straight oilhole of main shaft; Another procedure bores the straight oilhole of connecting rod; Because of every kind of crankshaft oil hole angle, crank spindle and connecting rod diameter require differently, this just causes every kind of bent axle all to need two sleeve clamps, except versatility poor; Also caused the manufacturing cost of anchor clamps high, the production cycle is long, clamping times is many, at the bottom of the efficient.
At present, bore the oilhole anchor clamps on the crankshaft journal using radial drilling machine to bore, using more is the clamp mechanism of spiral and presser type.In the clamp mechanism design, eccentric wheel or spiral clamp mechanism are to use more a kind of clamp mechanism.The Eccentric Clamping Mechanism process operation is convenient, clamping is rapid, and shortcoming is that clamping force is all little with the clamping stroke.Spiral clamps that mechanism structure is simple, reliable clamping, versatility are good, and because lead angle is little, and the self-locking property of spiral clamp mechanism is good, and clamping force is with to clamp stroke all bigger, and shortcoming is manual clamping, clamps slow motion, labour intensity is big.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art, provides a kind of rational in infrastructure, easy to assembly, makes simply, and it is big to clamp stroke, and efficient is high, and labour intensity is low, is suitable for the eccentric wheel clamping device that various axle classes clamp.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of eccentric wheel clamping device, and it comprises clamp body, supporting base, pressing plate, backing plate, handle, eccentric wheel, supporting base is installed on the clamp body; Backing plate is installed on the supporting base by level and vertical direction, it is characterized in that the supporting base front end installs one up and down respectively and compress a pillar and an annular screw, and the annular screw other end is hinged with the pressing plate of hinge pin and bottom fluting; Pressing plate middle part is provided with elongated hole and compresses the pillar activity and cooperate; The pressing plate bottom connects a pull bar, and the lower end of pull bar connects a spring, and the spring other end links to each other with journal stirrup bolt on the supporting base; Compressing pillar passes the elongated hole that pressing plate is provided with and is hinged with bearing pin and the eccentric wheel that is provided with fluting; The eccentric wheel that has a handle is pressed on the pressing plate outside, compresses the eccentric wheel of shore supports through rotation, utilizes eccentric wobbler action to compress the promotion pressing plate; Pressing plate rotates around the hinge pin that annular screw supports, and top compresses or unclamps part.
The present invention is said to be compressed the screw thread that pillar is provided with through an end and is installed in the screwed hole of supporting base, and the outside also is provided with a location nut.Compress the pillar other end and pass the elongated hole that pressing plate is provided with and be hinged with bearing pin and the eccentric wheel that is provided with fluting, elongated hole and eccentric fluting all play the guiding role on the pressing plate, and the direct clamping platen of eccentric wheel compresses part through pressing plate.The said threaded portion that compresses pillar can screw in nut and be screwed on the supporting base again, through the nut location, realizes the amplitude adjustment of hold-down mechanism, thereby compresses different accessory sizes.
On the said annular screw of the present invention was installed in the screwed hole of supporting base, the annular screw outside also was provided with a location nut, and the two cooperates screw-ins, and adjustable extension elongation of adjusting an annular screw is with the part of suitable pressing plate clamping different-diameter.
The present invention adopts the rotation of eccentric wheel control pressing plate, utilizes eccentric wobbler action to compress the promotion pressing plate, and pressing plate rotates around the hinge pin that annular screw supports, and top compresses or unclamps part.Against existing technologies, the present invention is rational in infrastructure, and is easy to assembly, low cost of manufacture, and highly versatile, it is installed in clamping device on the desired location according to the accessory size of different bent axles, is applicable to the clamping of various crankshaft parts.
