Abstract
The utility model relates to an eccentric-lifting pin hole positioning device. The eccentric-lifting pin hole positioning device is characterized in that a motor and a speed reducer of the motor are arranged on a supporting frame; a crank is arranged on an output shaft of the speed reducer; an eccentric rotating shaft is arranged on the crank; the axis of the eccentric rotating shaft is in eccentric and parallel arrangement with the output shaft of the speed reducer; a supporting roller bearing is arranged at the end part of the eccentric rotating shaft by a bearing seat; a positioning bracket is fixed on the supporting frame; a guide sleeve is fixed on the positioning bracket; a lifting guide pin is inserted in the guide sleeve in a sliding manner; and the supporting roller bearing extends into the lower part of the bottom end part of the lifting guide pin. The eccentric-lifting pin hole positioning device has the advantages that the eccentric mechanism is adopted for realizing the reciprocating movement of the lifting pin and finishing action, so that the speed reducing motor can be effectively protected; and when faults occur, the motor can operate still without being burnt off; and the structure is simple and reliable.
Description
Technical field
The utility model relates to a kind of sled device that is mainly used in the car assembling travel line at the registration device that rolls on the bed, especially a kind of eccentric lift pin holes registration device.
Background technology
The sled device is the transportation device in the travel line, generally is used for transporting vehicle body, and sled is positioned at the top of rolling bed, contact with roller on rolling bed, advances through the rotation drive of rolling a upper roller.And the sled device is rolling the accurate location on the bed and is preventing that it from moving, and accomplishes through registration device.Registration device in the past is to be main with gear-driven form, through the swing of two gear meshing, drives actuating unit and positions, owing to be the transmission of rigidity, safety factor is low, does not have fender guard, be easy to damage reducing motor, and noise is higher.Owing to be gear mesh, need certain lubricated maintenance, can not be used for harsh environment.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of simple in structure, reliable operation, the eccentric lift pin holes registration device low to space requirement are provided.
The technical scheme that provides according to the utility model; Said eccentric lift pin holes registration device; Be included in motor and the reductor thereof installed on the bracing frame, on the output shaft of reductor, crank be installed, eccentrically weighted shaft is installed on crank; The axis of eccentrically weighted shaft and the output shaft of reductor are eccentric and laterally arrange, and through bearing seat the support roller bearing are installed in the end of eccentrically weighted shaft; On bracing frame, be fixed with locating support, on locating support, be fixed with orienting sleeve, sliding plug has the up-down guide finger in orienting sleeve, and said support roller bearing stretches into the below, bottom of up-down guide finger.
Bottom at the up-down guide finger is fixedly connected with train wheel bridge; Below train wheel bridge, be provided with lower plate; Have the gap between train wheel bridge and the lower plate, train wheel bridge and lower plate are fixed through binding bolt, and said support roller bearing stretches in the gap between train wheel bridge and the lower plate.
Outside said binding bolt, be socketed with axle sleeve.
The utlity model has following advantage:
That 1, adopts that eccentric stiffener realizes lift pin moves back and forth execution, like this can actv. protection reducing motor, and when breaking down, motor still can turn round and can not be burnt like this;
2, simplify the structure, amount of parts reduces, and cost reduces.Owing to become the form that linear reciprocation moves to the clamping of swing location, reduced requirement to the space, shortened the stroke of action, improved efficient;
3, equipment adopts the parts and the sealing element of self-lubricating more, can be non-maintaining, and less demanding to working environment.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the birds-eye view of the utility model.
Fig. 3 is the scheme of installation of locating dowel pin in the utility model.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure: this off-centre lift pin holes registration device; Be included in motor and the reductor 1 thereof installed on the bracing frame 7; Crank 2 is installed on the output shaft of reductor 1; Eccentrically weighted shaft 3 is installed on crank 2, and the output shaft of the axis of eccentrically weighted shaft 3 and reductor 1 is eccentric and laterally arranges, and through bearing seat support roller bearing 4 is installed in the end of eccentrically weighted shaft 3; On bracing frame 7, be fixed with locating support 6, on locating support 6, be fixed with orienting sleeve 10, sliding plug has up-down guide finger 5.3 in orienting sleeve 10, and said support roller bearing 4 stretches into the below, bottom of up-down guide finger 5.3.
Be fixedly connected with train wheel bridge 5.1 in the bottom of up-down guide finger 5.3; Below train wheel bridge 5.1, be provided with lower plate 5.2; Has the gap between train wheel bridge 5.1 and the lower plate 5.2; Train wheel bridge 5.1 and lower plate 5.2 are fixed through binding bolt, and said support roller bearing 4 stretches in the gap between train wheel bridge 5.1 and the lower plate 5.2.
Outside said binding bolt, be socketed with axle sleeve 5.4.
When reductor 1 begins to rotate; Drive rotating shaft 3 through crank 2 and carry out the off-centre rotation around the center of reductor 1 with eccentrically weighted shaft 3 top support roller bearings 4; Because support roller bearing 4 can only be train wheel bridge 5.1, lower plate 5.2 middle the moving of positioning component; And the up-down guide finger 5.3 in the positioning component is mounted in the orienting sleeve 10 of locating support 6, and can move up and down, like this when support roller bearing 4 during around the rotation of the spindle eccentricity of reductor 1; Promotion train wheel bridge 5.1, lower plate 5.2 drive up-down guide fingers 5.3 and in the orienting sleeve 10 of support 6, move up and down execution.
And the startup of reductor 1 and stop be detector switch assembly 8 with trigger board 9 combinations accomplish, trigger board 9 is contained in to follow on the up-down guide finger 5.3 and moves up and down together, sends signal.This mechanism's accurate positioning, safe and reliable, motor is in locking state in the time of in working order, just in case signal is malfunctioning, the rotation that motor also can not stop, and can not burn out motor.In orienting sleeve 10 holes, self-lubricating bearing 11 is housed, can makes gliding smoothing like this, prevent the wearing and tearing of locating dowel pin.
