Description
Technical Field
The invention relates to hardware, in particular to a hardware clamping tool.
Background
Application publication No. CN 109015040A's patent document discloses a prevent hardware centre gripping frock of warping, has first clamping jaw and second clamping jaw on the draw runner to cooperate, and first clamping jaw and second clamping jaw distribute along the length direction of draw runner, and first clamping jaw and second clamping jaw can only move along the length direction of draw runner. When the long banding hardware of centre gripping, the head end of the tight hardware of first clamping jaw clamp, the tail end of the tight hardware of second clamping jaw clamp because first clamping jaw and second clamping jaw can not rotate relative the draw runner, consequently, first clamping jaw and second clamping jaw can make the hardware take place to buckle.
Disclosure of Invention
The technical problems solved by the invention are as follows: when stabilizing centre gripping strip hardware, how to avoid the hardware to be bent by the centre gripping worker clamping.
In order to solve the technical problems, the invention provides the following technical scheme: the utility model provides a hardware centre gripping frock of preapring for an unfavorable turn of events shape, includes base, first clamping jaw and second clamping jaw, and first clamping jaw and second clamping jaw are installed on the base, and the length direction of first clamping jaw and second clamping jaw along the base distributes, and first clamping jaw sliding fit is on the base, and the length direction that first clamping jaw only can follow the base removes, and the base is equipped with the cylinder part, and the second clamping jaw is equipped with the hoop, the hoop cover is established in the cylinder part is last.
According to above-mentioned technical scheme, the head end of the rectangular form hardware of first clamping jaw centre gripping, the tail end of second clamping jaw centre gripping hardware because the second clamping jaw can rotate around cylindrical part, consequently, the tail end of hardware has certain degree of freedom, can not rotate around first clamping jaw because of its tail end of second clamping jaw centre gripping, leads to the hardware crooked. So, under the circumstances of the stable centre gripping strip hardware of first clamping jaw and second clamping jaw, can avoid the hardware to be bent by centre gripping frock clamp.
As an improvement of the above technical scheme, the second clamping jaw is provided with a second upper clamp and a second lower clamp, the head end of the hoop is the second lower clamp, and the tail end of the hoop is positioned below the second lower clamp; a screw rod assembly is matched on the second clamping jaw and comprises an inner screw rod, an outer screw rod and an elastic piece; the top end of the outer screw rod is provided with a limiting ring which can be pressed on the second upper clamp in a propping manner, the outer screw rod downwards passes through the through hole on the second upper clamp, and the bottom end of the outer screw rod is in threaded connection with the second threaded hole on the second lower clamp; the outer screw rod is hollow, the inner screw rod is screwed in the outer screw rod, the elastic piece is arranged in the outer screw rod and sleeved on the inner screw rod, an inner convex ring is arranged at the bottom end of the outer screw rod, the bottom end of the elastic piece is pressed on the inner convex ring, and the top end of the elastic piece is pressed on the inner screw rod; the tail end of the hoop is provided with a third threaded hole, the inner screw rod can protrude downwards to the outer screw rod, and then the inner screw rod penetrates through the second threaded hole to be in threaded connection with the third threaded hole.
Under the prerequisite of the tight hardware head end of first clamping jaw clamp, the tail end of second clamping jaw centre gripping hardware again utilizes spanner or other rotary tool to rotate interior screw rod, because the existence of elastic component, the elasticity of elastic component can't be overcome to interior screw rod and relative outer screw rod downstream, and interior screw rod drives outer screw rod synchronous rotation, and outer screw rod moves down along the second screw hole, the spacing ring supports to press on the second presss from both sides, and the second presss from both sides down and presss from both sides tight hardware jointly. After the hardware is clamped, the outer screw rod cannot move downwards continuously, the inner screw rod continues to rotate, the inner screw rod overcomes the elasticity of the elastic piece and moves downwards relative to the outer screw rod, the bottom end of the inner screw rod protrudes downwards out of the outer screw rod, then protrudes downwards out of the second threaded hole, extends into the third threaded hole and is in threaded connection with the third threaded hole. The larger the downward movement of the inner screw rod is, the larger the deformation of the elastic piece is, the larger the accumulated elastic potential energy is, the larger the acting force of the screw rod assembly to enable the second lower clamp and the tail end of the hoop to move towards each other is, the hoop is clamped on the cylindrical part, and the second clamping jaw is fixed. The fixed of second clamping jaw position is after the tight hardware of second clamping jaw clamp, and the second clamping jaw can not press from both sides curved hardware, so, guaranteed promptly that the hardware is by stable centre gripping, avoid it to be pressed from both sides again and bend.
