Description
Technical field
The utility model relates to automobile welding and assembling clamp field, specifically a kind of manual-automatic integrated self-locking clamping device.
Background technique
With being growing more intense for automobile industry competition, China's automobile industry gradually changes, the degree of automation
Gradually increasing, this brings new market demands to weld car line Chevron Research Company (CRC):
(1) product needs the requirement of fast responding market.
It is required that there is the ability of powerful autonomous rapid product development in the Chevron Research Company (CRC) that is welded and integrates the ability of all kinds of resources, if
Meter manufacturing technology has stronger flexibility, in the hand that new product can be delivered to client under conditions of lower cost；
(2) shorter production life cycle:
Nowadays car, the life cycle of SUV are shorter and shorter, and update is advanced by leaps and bounds.The week in service life of new product from now on
Phase will also further shorten, and about 3 to four years even shorter, and soldering cramping apparatus manufactures and designs the period from original contracting in 1 year
Short is four to six months even shorter
(3) cost is reduced as far as possible under the premise of guaranteeing quality and usability:
Accelerating while designing and developing of new model, should also actively take measures to reduce research and development and production cost, integration
All kinds of resources take measures in terms of trial-production is researched and developed in localization to reduce cost.
For traditional cylinder clamping mode, substantially Japanese standard used, the advantage of Japanese standard is exactly to tie
Structure is lightly exquisite, and cost price is cheap, and manufacture and period are simple and fast, and cylinder cost is 300~500 yuan or so.Such as Fig. 1
It is shown, when the drive rod b1 driving rotary swinging arm e1 of cylinder a1 is carried out after connecting rod pivot pin c1 rotation, arrival supporting block d1
Clamp operation, once cylinder disconnects gas source, clamping force just fails, until and just not having the effect of clamping.
Europe system standard has effectively evaded this disadvantage to a certain extent, as shown in Fig. 2, Europe system Standard Cylinder a2
(TUNKERS brand) drives rotary swinging arm e2 to rotate around connecting rod pivot pin d2 after ventilation, disconnects gas source after clamping again
Words times so remain clamping force since cylinder carries limit function, but cylinder cost is relative to higher, price 1000~
1200 yuan, so traditional clamping mode will not generally favor the mode of this Europe cylinder clamping.
Utility model content
Technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to clamp in former Japanese Standard Cylinder
It is improved on the basis of mode, has installed the locking dress of a set of independent research additional on the basis of the cylinder does piston motion
It sets, realizes self-locking function.
In order to solve the above-mentioned technical problem, the utility model discloses a kind of manual-automatic integrated self-locking clamping device, packets
Include cylinder, air cylinder fixed plate, cylinder fixed connecting base, cylinder connector, position limit arm, L-type rotary swinging arm and link block；
The cylinder is fixed on the bottom of cylinder fixed connecting base by air cylinder fixed plate；It is defeated that cylinder connector is fixed on cylinder
The end of shaft；The middle part bending place of L-type rotary swinging arm is connect at the top of cylinder fixed connecting base by the first fulcrum pin axle, close

Switch upper-arm circumference makes rotating motion around the first fulcrum pin；
The bottom of the position limit arm is fixed on cylinder fixed connecting base, and top horizontal bends and is located on cylinder connector
Side, moves further up for limiting link block；Position limit arm bending place is equipped with clamping block, when cylinder connector is moved upwards up to this
When place, top and clamping block clamping are still able to maintain the gripping orientation after cylinder is died；
Connected by hollow connecting shaft with the handle connecting shaft pin being located on cylinder fixed connecting base in the middle part of the cylinder connector
It connects；Hollow connecting shaft passes through the through slot in the middle part of cylinder connector there are the end of elliptical hole, and one is equipped in through slot across oval logical
The pivot pin in hole；The hollow connecting shaft other end is fixed on handle connecting shaft pin；The handle connecting shaft pins position is in the first fulcrum pin
Lower section, run through cylinder fixed connecting base, outer end connect handle；After cylinder connector and clamping block clamping, by rotating hand
Handle so that hollow connecting shaft rotates and gives cylinder connector one downward active force so that cylinder connector separated with clamping block from
And it unlocks.
Wherein, described link block one end is connect by the second fulcrum pin axle in the end of the nearly middle part bending place of L-type rotary swinging arm,
The other end is connect by the second fulcrum pin axle at the top of cylinder connector.
Further, the lower section that the cylinder fixed connecting base is located at L-type rotary swinging arm is equipped with an outwardly extending platform,
For platform equipped with a supporting block, control L-type rotary swinging arm rotation angle is 90 °, when L-type rotary swinging arm is in level, length
Arm section is located in supporting block, and cylinder connector is maximum with clamping block contact surface by clamping block clamping.
Preferably, it screws up formula using screw thread between the cylinder connector and the output shaft of cylinder to be attached, cylinder connector
Lower part carries internal thread hole, and the output shaft head of cylinder carries external screw thread, is tightened by cooperation.
Further, the output outer shaft sleeve of the cylinder has a graphite copper sleeve, graphite copper sleeve primarily serve guiding and
Lubricating action.When the output shaft of cylinder moves upwards, at this moment graphite copper sheathing ensure that cylinder output shaft is transported upwards as guiding
Dynamic verticality.Graphite bush is embedded with graphite simultaneously, moves upwards for cylinder output shaft and plays the role of lubrication, reduces
Frictional force avoids kinetic energy rejection.
It is fixed at the top of the graphite copper sleeve by graphite copper sleeve pressing plate, avoids transporting upwards because of the output shaft of cylinder
Tractive force that is dynamic and generating ejects graphite bush.
