Detailed Description

Referring to fig. 1, 3, a rigidity setter comprises a steel bar 10 and a presser 20 at both ends of the bar, the ends of the bar being capable of cooperating with the presser; the pressing tool comprises a pressing tool seat 21 and a rotating part 22 hinged on the pressing tool seat, the rotating part is provided with a bayonet 23, and the end part of the steel bar can be matched with the bayonet.

The parts, components, products are placed on the table between at least two hold-downs 20. The middle of the bar 10 is pressed against the part, component, product. The left presser base of the part, component or product is engaged with the left end of the steel bar 10, specifically, the rotary member 22 is rotated, and the bayonet 23 is engaged with the left end of the steel bar to lock the engagement state of the left presser base with the left end of the steel bar. The cooperation of the tamp seat on billet right-hand member and part, product right side, specifically, the rotating member is rotatory, its bayonet socket and billet right-hand member block to the cooperation state of locking billet right-hand member and right side tamp seat. The steel bar is elastically deformed to a certain extent, and both ends of the steel bar are pressed downward, so that the parts, components and products are pressed against the worktable and positioned under the elastic force of the steel bar 10.

With reference to fig. 1 and 2, as an option, the number of the pressing tools 20 is a plurality of pairs, any pair of pressing tools is arranged in bilateral symmetry, the left pressing tool of any pair of pressing tools is matched on the left guide rail 41, the right pressing tool of any pair of pressing tools is matched on the right guide rail 42, and a locking screw 50 is screwed on any pressing tool. A pair of pressing tools is matched with a steel bar. A plurality of pairs of pressing tools are matched with a plurality of steel bars to compress a plurality of positions of the product, so that the stable positioning of the product is realized. In order to adapt to the structures of different products, the pressing tool can move on the corresponding guide rail to adjust the position, so that the position of the product pressed by the steel bar is adjusted. After the hold-down tool is in the appropriate position on the corresponding guide rail, the operator tightens the locking screw to fix the position of the hold-down tool.

The left and

right side rails

41, 42 are mounted on the countertop, or the left and right side rails are mounted on a base that is mounted or placed on the countertop.

With reference to fig. 3 to 5, the rotating member 22 includes a front clamping member 24, a rear clamping member 25, and a handle 26, the front clamping member and the rear clamping member are symmetrically arranged in front and rear, both the front clamping member and the rear clamping member are connected with the handle, and the front clamping member and the rear clamping member are provided with the bayonet 23; the front clamping piece is hinged with the front side wall of the pressing tool seat 21, and the rear clamping piece is hinged with the rear side wall of the pressing tool seat. The front and

rear stoppers

24 and 25 are engaged with the ends of the bar 10, respectively. So design, can improve billet tip and tamp 20 complex stability.
