The utility model discloses structural design scientific and reasonable, easy and simple to handle, the auxiliary of specially adapted flexible welding platform is installed, and location locking is high -efficient convenient.
Description
Technical field
This utility model belongs to automobile production conveying equipment and manufactures field, particularly to a kind of Flexible Manufacture platform fast locking pin for the welding of slide plate skeleton.
Background technology
At present, automobile assembling skateboard platform is mainly by slide plate skeleton and adhere to wooden cover plate thereon and constitute, and slide plate skeleton part is that shape is welded, and the group of weldment completes on 40mm steel plate platform. There is many deficiencies in existing metal platform: 1. all frocks, spacing, position of the fulcrum are really established a capital the veteran riveter of needs (skilled industrial worker) and determined by the mode of unwrapping wire, and process is more complicated, wastes time and energy, and frock precision is low; 2. frock is single use, needs manual polishing to fall after using, and is polished flat platform relevant position, and process wastes time and energy, and through repeatedly polishing, platform plane degree is substantially reduced, and affects product quality; 3. after frock bearing completes, can not dismantle before batch production, take work place for a long time, waste resource.
Applicant have developed the flexible welding platform of a kind of automobile assembling skateboard platform slide plate skeleton, by processing the connecting hole of uniformly arrangement at equal intervals at platform upper surface, location-plate and the fixing of hold-down mechanism all adopt bolt to be fixed, convenient and swift and reusable. But, location-plate is installed according to conventional bolt with locking of connecting hole, then there is installation effectiveness low, the problem wasted time and energy. According to common step pin, then can only realizing positioning function, other hold down gags need to be coordinated to be used in conjunction with, structure is complicated, takes up room big. The common locking pin that expands relies on the expansion locking of some concentric steel balls, it is impossible to what realize different-thickness auxiliary and platform is effectively connected locking.
Summary of the invention
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, installs quick flexible welding platform fast locking pin.
This utility model solves its technical problem and is achieved through the following technical solutions:
A kind of flexible welding platform fast locking pin, it is characterized in that: be mainly made up of strain pin, expansion set, nut and packing ring, the top of described strain pin is shaped with thread segment, in the engagement of this thread segment, described nut is installed, the outside of described strain pin is set with described expansion set, the bottom of described strain pin is shaped with the expansion arc coordinating also flaring with expansion set, and mounting gasket on the strain pin between described nut and expansion set, strain pin top is shaped with pin-and-hole.
And, between described nut and packing ring, spring shim is installed.
Advantage of the present utility model and having the beneficial effect that
1, this flexible welding platform fast locking pin, during use, during use, locking pin is inserted auxiliary and platform connecting hole, strain pin circular hole is inserted with thin round steel or other instruments, blocking, by nut screwing clamping, while tightening, strain pin rises, by expansion set lower end distending, the principle of expansion bolt is utilized to be locked by auxiliary.
2, this flexible welding platform fast locking pin, expansion set is fixed with being effectively connected of platform with being applicable to common different-thickness auxiliary.
3, this utility model scientific structure design is reasonable, easy and simple to handle, and the auxiliary being particularly well-suited to flexible welding platform is installed, and positioning and locking is efficiently convenient.

Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following example are illustrative, is not determinate, it is impossible to limits protection domain of the present utility model with this.
A kind of flexible welding platform fast locking pin, it is mainly made up of strain pin 2, expansion set 1, nut 5 and packing ring 3, the top of strain pin is shaped with thread segment 6, in the engagement of this thread segment, nut is installed, the outside suit expansion set of strain pin, the bottom of strain pin is shaped with the tensioner mouth 7 with expansion set lower end and coordinates the expansion arc 8 of also flaring, mounting gasket on the strain pin between nut and expansion set. Spring shim 4 is installed between nut and packing ring.
During use, fast locking pin 11 of the present utility model is installed in the connecting hole of location-plate 10 and flexible welding platform 9. Expansion set external diameter mates with platform aperture, and expansion set lower end has 6 elongated slots, and opening part is tapered. Strain pin lower end is tapered, and maximum diameter is more than expansion set internal diameter, and there is screw thread and the through hole of suitable length upper end. During use, locking pin is inserted auxiliary and platform connecting hole, as it is shown on figure 3, insert strain pin circular hole with thin round steel or other instruments, blocking, by nut screwing clamping, while tightening, strain pin rises, by expansion set lower end distending, the principle of expansion bolt is utilized to be locked by auxiliary. Realize the fixing of the auxiliary such as location-plate, hold-down mechanism and flexible welding platform, there are location and two kinds of functions of locking.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope without departing from this utility model and claims, various replacements, to change and modifications be all possible, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
Claims (2)
