Abstract

The invention relates to a centering, positioning, self-locking and clamping device used in an automatic press mounting special machine of an automobile transmission shaft. In the device, differential crank-slider mechanisms are adopted to realize the centering and the positioning of a fixture under the drive of a power source; and a motion dead point of a connecting rod is utilized to realize the self-locking and the clamping. The device is structurally characterized by mainly comprising a mounting baseplate, V-shaped block mounting seats, V-shaped positioning blocks, linear guide rails, sliders, an air cylinder, a central spindle, an oscillating bar seat, connecting bars and the like. The air cylinder pushes an oscillating bar, and two sets of the differential crank-slider mechanisms are used for driving the V-shaped positioning block to synchronously move in a centering manner; and when hinge points of the oscillating bar seat, the connecting bars and the sliders are located on the same straight line in a slider moving direction, the V-shaped positioning blocks arranged on the sliders move in a self-locking state, so that a workpiece is self-locked and clamped. The device is used in occasions in need of automatic positioning and clamping, such as a universal-joint fork or an axle pipe and the like in the automatic press mounting special machine of the automobile transmission shaft, the positioning precision can be improved, higher clamping force can be obtained, and the structure can be simplified.

Summary of the invention
The object of the present invention is to provide a kind of centering location and self clamping device that truck drive shaft press-fits special plane automatically that be used for, adopt the self-locking clamping mode, be used to replace former non-self-locking clamping mode, realization clamps the location of driving shaft universal joint fork axle journal or central siphon, to improve positioning accuracy, obtain larger clamping force, and the purpose of simplified structure.
For realizing improving positioning accuracy, obtain larger clamping force, and the purpose of simplified structure, design of the present invention is as follows:
The centering location is to adopt the differential slider-crank mechanism of two covers with the basic principle of self clamping device, when the pin joint of driving lever, follower lever and slide block was positioned on the same straight line of slide block movement direction, the motion of slide block was in self-locking state in the slider-crank mechanism; And adopt the differential mode of two cover crank slide block mechanisms, can realize the centering motion of two slide blocks by a drive power source.
According to the foregoing invention design, the present invention adopts following technical step:
A kind ofly be used for centering location and the self clamping device that power transmission shaft press-fits special plane automatically, comprise base plate, vee-block mount pad, V-arrangement locating piece, line slideway, slide block, cylinder, cylinder mount pad, mandrel, swing rod, connecting rod, connecting pin, stop screw and limit base etc. are installed.
Above-mentioned centering location with the structure of self clamping device is: one base plate is installed and is installed on the workbench that press-fits special plane, two line slideways are fixedly installed in to be installed on the base plate, two slide blocks slide on two line slideways respectively, fixed installation vee-block mount pad on it, the V-arrangement locating piece is fixedly installed on the vee-block mount pad; Mandrel is fixedly installed in to be installed on the base plate, swing rod is installed on the mandrel by two bearings, symmetry is installed two connecting pins on the swing rod flange, and two connecting rod rotations are mounted thereon, and the other end of two connecting rods is installed on the vee-block mount pad by the connecting pin rotation respectively; Cylinder mount pad is fixedly installed in to be installed on the base plate, and cylinder is installed in rotation it on, and the cylinder piston rod front end is equipped with Y and pitches Connection Block, and links to each other with fork on the swing rod by pin; Stop screw is fixedly installed in by limit base and installs on the base plate, and it is used for spacing to cylinder limit position, and connecting pin on the swing rod flange and slide block movement direction become self-locking state when guaranteeing to clamp in line.
The present invention has following conspicuous outstanding substantive distinguishing features and remarkable advantage compared with prior art:
The present invention adopts centering location and self-locking clamping mode, not only improves the positioning accuracy of axial workpiece center line, and by differential slider-crank mechanism, makes the demand that adopts small driving force can reach very big clamping force.Be applicable to power transmission shaft in enormous quantities press-fits automatically to be needed axis location and clamp in the production occasion, can improve positioning accuracy, reduce power, simplified structure.
Description of drawings
Fig. 1 is the overall structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Details are as follows in conjunction with the accompanying drawings for the preferred embodiments of the present invention:
Referring to Fig. 1 and Fig. 2, originally be used for centering location and self clamping device that power transmission shaft press-fits special plane, comprise that one will be contained in truck drive shaft and press-fits installation base plate (1) on the special plane workbench automatically, two vee-block mount pads (2), two V-arrangement locating pieces (3), two slide blocks (4), two line slideways (5), locating piece at the beginning of one (6), a mandrel (7), two bearings (8), a swing rod (9), four connecting pins (10), two connecting rods (11), a cylinder mount pad (12), a cylinder (13), a Y fork Connection Block (14), a pin (15), a stop screw (16), a limit base (17).Described two line slideways (5) are in line and align and be fixedly installed on the described installation base plate (1), described two slide blocks (4) are gone up at described two line slideways (5) and are slided, described two vee-block mount pads (2) are fixedly installed in respectively on described two slide blocks (4), and described two V-arrangement locating pieces (3) are fixedly installed on described two vee-block mount pads (2); Described mandrel (7) is fixedly installed on the described installation base plate (1), be positioned between two line slideways (5) on the center line, described swing rod (9) is movably installed on the described mandrel (7) by described two bearings (8), symmetry is installed two described connecting pins (10) on described swing rod (9) flange, described two connecting rods (11) one ends are installed on respectively on described two connecting pins (10), and described two connecting rods (11) other end is hinged with described two vee-block mount pads (2) by described two connecting pins (10) in addition respectively; Described cylinder mount pad (12) is fixedly installed on the described installation base plate (1), described cylinder (13) is hinged with described cylinder mount pad (12), described cylinder (13) piston rod front end is equipped with described Y fork Connection Block (14), and links to each other by the fixedly connected fork (18) of described pin (15) and described swing rod (9); Described stop screw (16) is fixedly installed on the described installation base plate (1) by described limit base (17), this stop screw (16) is in the right side of described Connection Block (14), and this stop screw (16) can be transposed by a nut (19) and is fixed on the limit base (17).
