Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 has schematically shown the operation principle sketch of the hold down gag in the utility model;
Fig. 2 has schematically shown the sketch map of the hold down gag under the impaction state; And
Fig. 3 has schematically shown the sketch map of the hold down gag of relaxed state.
The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Shown in Fig. 1-3, the hold down gag in the utility model comprises pedestal 1, has first articulated section and second articulated section on the pedestal 1.Hold down gag also comprises clamping lever 3, and first end of clamping lever 3 is articulated on said first articulated section, and second end of clamping lever 3 is a compressing end, and the end face of clamping lever 3 is the convex globoidal 4 that extends to the direction of second end along first end from clamping lever 3; Said hold down gag also comprises rotation depression bar 2, and first end of this rotation depression bar 2 is articulated on said second articulated section, and second end of this rotation depression bar 2 has the compressed part that cooperates with said convex globoidal 4.Because the existence of this convex globoidal 4 when making operation enough power need be provided, and generation acts on the reaction force on the hold-down mechanism thus; Thereby workpiece pressing reliably; Simultaneously, make also under impaction state that rotation depression bar 2 can remain on the clamping lever 3 to self-locking.
Shown in Fig. 1-3; When clamping lever 3 is turned round in the direction of arrow B, make clamping lever 3 and the surperficial butt of treating workpiece pressing, depression bar 2 is rotated in rotation in the direction of arrow A then; Rotation depression bar 2 is rotated to and clamping lever 3 state of contact; Thereby apply thrust F to clamping lever 3, this thrust F affacts and treats on the workpiece pressing, can realize compressing workpiece; Like this, compacted workpiece will not be moved in the process of processing, for example; To the steel construction group to welding process in; Make workpiece in welding process, use the hold down gag in the utility model, just can make workpiece be in the attitude of technological requirement, in addition always; The reversible deformation control that hold down gag in the utility model also can be used to weld is reaching designing requirement to guarantee the product after the welding.Preferably, the hold down gag in the utility model can adopt the mode of hammering to realize compressing and unclamp, thereby has improved production efficiency greatly, has good practical value.
Preferably, the compressing end of clamping lever 3 is provided with adjusting screw(rod) 5, thereby can regulate the position of clamping lever 3, makes to keep suitable cooperating between clamping lever 3 and the rotation depression bar 2, to be adapted to the workpiece of different size.For example, when the size of workpiece hour, can make the rotation depression bar 2 among Fig. 1 be in suitable height through adjusting screw(rod) 5, therefore, can not receive the influence of workpiece size and enough thrusts are provided.Preferably, the upper end of adjusting screw(rod) 5 has the through hole that radially extends along said adjusting screw(rod), adjusting screw(rod) 5 is regulated being used for.Preferably, the lower end of adjusting screw(rod) 5 has rotatable pressing piece, and this pressing piece acts on the compacted workpiece.
Shown in Fig. 1-3; Pedestal 1 comprises a gathering sill 6; The middle part of clamping lever 3 is extended with the guide part 7 that cooperates with said gathering sill 6 downwards; Through cooperating of said gathering sill 6 and guide part 7, clamping lever 3 is remained on the predetermined direction, in the process of work to avoid hold-down mechanism contingent skew under the effect of thrust.
Of Fig. 1-3, rotation depression bar 2 comprises that two are used for the clamping arm 9 that articulates with pedestal 1, and said compressed part is connected the end of said two clamping arms 9.Preferably, be formed with operating grip 8 on the said compressed part.
Hold down gag in the utility model is in use through rotation rotation depression bar 2; Power is delivered to clamping lever 3; Clamping lever 3 passes to workpiece to be compressed through adjusting screw(rod) 5 with power, thereby realizes compressing, so that product keeps some sizes in whole welding process; Knock pressure after the welding cooling and apply portion, can realize at once unclamping.In addition; Hold down gag during this practicality is new and ingenious can be according to product height, width and rigidity different, be designed to different specifications, different length, differing heights, to reach instructions for use; Further, a plurality of hold down gags are used simultaneously will obtain better technique effect.
Hold down gag in the utility model can adopt the quick workpiece pressing of the mode of knocking, have save time, the labour-saving characteristics, improved production efficiency greatly; In addition; Through the length of adjusting portion of design different size, in large, medium and small formed steel construction welding process, the hold down gag in a plurality of the utility model can use simultaneously; Satisfying the requirement of different length, height, with the assurance group in, when welding, realized the purpose that compresses fast.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
