Description
Technical field
The present invention relates to detection field of fixtures, particularly relating to a kind of for preventing box deformation during seal case air-leakage test and with the device of self-lock protection function.
Background technology
Seal case is a kind of conventional parts in manufacturing industry, and as water tank, fuel tank, gas tank etc., this base part mostly requires that casing has good sealing, does not allow to there is the phenomenons such as leakage, seepage.
The conventional means of inspection box body tightness has dry type and wet type two kinds, wherein dry type detection method is particularly conventional, namely first casing is sealed completely, the pressure gas of certain pressure is passed into again in casing, by air pressure, the fault location of gas from welding box body position is extruded, utilize Detecting medium (liquid) to detect leak site simultaneously thus point out producers to process leakage position.This check system is simple to operate, and result is obvious, with low cost, is widely adopted; But also there is its critical defect, casing plane especially can be caused when detecting thin-wall rectangular casing to produce plastic yield, release back plane occurs protruding, affect casing outward appearance and size, even make workpiece scrap.
Therefore, in actual production, often by increasing protective device, reinforced with protective device in advance at the position easily deformed, make box deformation in checkout procedure control in regime of elastic deformation, equal pressure off-load rear cabinet physical efficiency automatically restores to virgin state.According to the difference of box shape and the mode of production, scale, protective device adopts closed and open two kinds of the quick despatch of reinforcing frame usually, and the former is applicable to the production and processing of short run single variety, and the latter is applicable to the production and processing of multi items in enormous quantities.Generally, have certain production-scale enterprise and mostly adopt quick despatch open devices to protect casing, its structure is: by an adjustable C type semi open model framework, fixed framework one end, the other end promotes clamping plate by cylinder.During work, first workpiece is put into C type framework, then connect source of the gas and promote clamping plate by cylinder and need the face of protection to clamp casing, and then in casing, pass into pressure gas detect.This protective device, is directly pressed in cylinder in protective surface by clamping plate, and the protection of generation is determined by the pressure acted on cylinder piston, and pressure size is certain value; This protection is suitable for the protection in small box face; but for the casing that volume is larger; the pressure that the pressure gas passed in casing produces may be greater than the protection that cylinder produces, and during inspection, cylinder does not just have protective effect thus makes shielding failure cause box deformation like this.
Summary of the invention
For making protective device have compression auto-lock function, providing reliably protecting power, realizing workpiece quick despatch, the present invention proposes a kind of for preventing box deformation during seal case air-leakage test and with the device of self-lock protection function.
For this reason, technical scheme of the present invention is: casing airtight detection anti-deformation self-locking protecting device, comprise swivel bearing seat assembly, suspension rod, supporting traverse, swivel bearing seat assembly forms at a base exterior mounting plane thrust ball bearing, armshaft and suspension rod one end of thrust ball bearing with flat seat are socketed, and the lower end of base is fixedly connected with in the middle part of supporting traverse; Be connected with left socle in supporting traverse one end, be connected with left clamping plate at left socle lower end inside by bearing, it is characterized in that:
Be provided with a four-bar mechanism and a cylinder at the other end of supporting traverse, four-bar mechanism comprises left rocking bar, right rocking bar, upper elbow and arm, lower elbow and arm and web joint;
Left rocking bar and right rocker shaft are to being arranged in parallel, and left rocking bar is connected with web joint respectively by bolt with the upper end of right rocking bar, and web joint is connected on supporting traverse;
Upper elbow and arm one end and lower elbow and arm one end by a bolt and cylinder piston rod hinged, the other end of upper elbow and arm is fixed on web joint, and the other end of lower elbow and arm is fixed on right rocking bar, and cylinder is fixed on web joint;
Be connected with right support in the lower end of left rocking bar and right rocking bar, left rocking bar and rocking bar are connected to the side, upper end of right support respectively by bolt, are provided with right clamping plate at right support lower end inside.
One for technique scheme is improved and is: for accurately locating and all-directional rotation workpiece, described right clamping plate are connected by leading screw with between right support, are provided with rotary handle with handled easily at leading screw end.
Beneficial effect:
The rectilinear motion of original right clamping plate, by installing four-bar mechanism additional, is changed into swing to-and-fro movement by the present invention, and fixture protection is changed with the change of compression pressure in casing; And by upper and lower elbow arm and cylinder piston rod hinged, piston rod drives two elbow arm motions, this four-bar mechanism is made to realize self-locking when angle is less than a certain angle between two elbow arm, thus ensure that right clamping plate are in self-locking state when clamped position, for casing provides stable holding force, effectively to avoid box deformation.After casing air-leakage test completes, moved by cylinder piston rod, in drive, lower elbow and arm motion can remove self-locking, and four-bar mechanism drives right support to move to right, and the right clamping plate of fixture are opened, unloaded workpiece, realize the quick despatch of workpiece.
