further, one side of the left slider cover plate 7, which is far away from the left stamping slider 4, is provided with a left fixing screw 91, and the left fixing screw 91 is used for locking the left slider cover plate 7.
Further, the right spring 62 is located above the tooling fixture base 1, a right slider cover plate 8 is arranged on one side, away from the tooling fixture base 1, of the right stamping slider 5, and the right slider cover plate 8 covers the right spring 62 and the right stamping slider 5 simultaneously.
Further, a right fixing screw 92 is arranged on one side, away from the right stamping slider 5, of the right slider cover plate 8, and the right fixing screw 92 is used for locking the right slider cover plate 8.
Furthermore, both sides of the movable handle 3 are provided with positioning holes, both sides of the inside of the opening of the handle body 2 are respectively provided with a left circular truncated cone and a right circular truncated cone, and the positioning holes on both sides of the movable handle 3 are respectively in positioning fit with the left circular truncated cone and the right circular truncated cone of the handle body 2.
Furthermore, the two side surfaces of the movable handle 3 are bent towards the inner side surface by 3 to 5 degrees, so that the positioning holes in the movable handle 3 are aligned with the left and right innermost round tables of the handle body 2 during assembly, and then the tooling is used for punching, so that the progress is improved, the assembly quality and the product effect are ensured, and the labor is saved.
According to above-mentioned preferred embodiment, the utility model discloses an expanding frock clamp, its technical essential sums up as follows.
the expandable tooling fixture comprises a tooling fixture base 1, a punch 10 and the like, see the exploded view of fig. 2.
The key point is that the design of the tool clamp base 1 reserves the space position for placing the handle main body 2 and the movable handle 3, and then the tool clamp base 1 is also provided with a left stamping slide block 4 and a right stamping slide block 5 which can move left and right, so that the left and right springs 61 and 62 positioned at two sides and the left and right slide block cover plates 7 and 8 for positioning are limited, and finally the left and right slide block cover plates 7 and 8 are locked by left and right fixing screws 91 and 92.
when the handle body 1 and the movable handle 3 are put in, the punch 10 is lifted to be on the uppermost surface, i.e., the punch expansion is not performed, as shown in fig. 1.
The left and right punch sliders 4 and 5 are not subjected to the pressing force of the inclined surface of the punch 10, and are moved toward the reference surface a and are in contact with each other in a stationary state by the reaction force of the left and right springs 61 and 62 on the left and right sides, as shown in fig. 3.
The positioning holes of the movable handle 3 positioned on the two side surfaces and the round table on the inner side of the opening of the handle body 2 are not inserted and assembled in a two-point position A and a two-point position B.
When the punch 10 moves down and starts to contact the left and right punching sliders 4 and 5, the left and right punching sliders 4 and 5 are pushed to move towards two sides by the action of the inclined surface component force when the component force is larger than the reaction force of the left and right springs 61 and 62, and the positioning holes on the two side surfaces of the movable handle 3 are driven to be inserted into the round tables on the inner side of the opening of the handle body 2, as shown in fig. 4.
In the descending displacement we can see that the uppermost points a and B of the two sides of the movable handle 3 are rotated to the outside, see fig. 3.
As the punch descends, the operation of expanding the punch is completed when two points a and B contact the inner side surface of the opening of the handle main body 2 until they are completely contacted. At this point, the left and right punch slides 4, 5 are seen to be separated by a distance at the left and right ends. The punch 10 is lowermost as shown in fig. 5A and 5B.
The state after completion of the punch expansion is shown in fig. 5A and 5B.
When the punch 10 is retracted upward from the lowermost end, the component force on the inclined surface of the punch 10 decreases, and the reaction force of the left and right springs 61,62 also increases. As the punch 10 ascends, the left and right press sliders 4, 5 run toward the reference plane a by the reaction force of the left and right springs 61,62, and it is found that points E and F are clearly separated, as shown in fig. 6A and 6B.
With the retraction of the punch 10, all actions return to the state when not initially punched, as shown in fig. 1.
To this end, one assembly expansion operation is completed, and the same working process can be successively repeated.
It will be apparent to those skilled in the art that modifications and variations can be made in the above-described embodiments, or some features of the invention may be substituted or omitted, and any modification, substitution, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
