Description

Technical Field

[0001] The invention belongs to the technical field of fasteners, and more particularly, relates to a handheld nut machine chuck. Background Art

[0002] In the field of mechanical engineering, nuts are very common fasteners, which are often used in conjunction with bolts or screws. When in use, the nuts need to be tightened with the help of external force to achieve a tightening effect. In the prior art, hook wrenches are often used to perform tightening operations. During operation, operators hold the hook wrenches and manually tighten the nuts. The manual operation has high labor intensity and low operation efficiency. In addition, when tightening the nuts manually, it is impossible to accurately control the tightening torque acting on the nuts. Operators rely on experience to judge whether the nuts are tightened, and often make inaccurate predictions, resulting in inadequate tightening of the nuts, or excessive force causing thread slippage and damage to the nuts. With the development of mechanization and automation industries, a type of handheld nut machine that can tighten nuts has appeared on the market. However, the chuck of the traditional handheld nut machine will get stuck in the nut during use, resulting in slow production efficiency and difficulty in removing the stuck nuts.

[0003] The utility model can be used conveniently and can also prevent the nut from getting stuck. Utility Model Content

[0004] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provides a handheld nut machine chuck, which is convenient to use and can avoid the occurrence of nut sticking phenomenon.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a handheld nut machine chuck, comprising: a chuck body, a nut inlet tube is installed at the upper right end of the chuck body, a right clamping block is installed at the lower right end of the chuck body, and a left clamping block is installed at the left end of the right clamping block.

[0006] A further preferred solution is that a limiting through hole is provided in the center of the clamp body, and a nut rod is arranged in the limiting through hole.

[0007] A further preferred solution: a first mounting hole is opened through the center of the left end of the clamp body, a first connecting through hole is opened through the upper left end of the left clamp block, a third fixing pin is installed in the first mounting hole and the first connecting through hole, a left mounting groove is opened at the left end of the clamp body, and a left clamp block is installed in the left mounting groove.

[0008] A further preferred solution: a second mounting hole is formed through the lower right end of the clamp body, a second connecting through hole is formed through the upper right end of the right clamp block, a first fixing pin is installed at the second mounting hole and the front end of the second connecting through hole, a second fixing pin is installed at the rear end of the second mounting hole and the second connecting through hole, a right mounting groove is formed at the lower right end of the clamp body, and a right clamp block is installed in the right mounting groove.

[0009] A further preferred solution is that a first spring is sleeved on the outer side of the third fixing pin, and a second spring is sleeved on the outer side of the first fixing pin and the second fixing pin.

[0010] A further preferred solution is that a spring limit platform is provided on the outer side of the right clamping block.

[0011] A further preferred solution is that a left clamping groove is provided on the right side of the top end of the left clamping block, and a right clamping groove is provided on the left side of the top end of the right clamping block, and the left clamping groove and the right clamping groove fit with the nut to be tightened.

[0012] Beneficial effects:

[0013] 1. The left clamp block and the right clamp block are provided to limit the position of the nut to be tightened. When the nut to be tightened passes through the nut inlet tube and enters the lower end of the clamp body, it will slide into the center of the left clamp groove and the right clamp groove to limit the position of the nut to be tightened, so that the nut rod can absorb the nut to be tightened and avoid the occurrence of the nut jamming phenomenon;

[0014] 2. By providing the first spring and the second spring, the effect of resetting the left clamp block and the right clamp block is achieved. When the nut rod pushes the left clamp block and the right clamp block open and then moves upward to return to the original position, the left clamp block and the right clamp block rebound and close by the elastic force of the first spring and the second spring.

[0015] 3. In summary, this type of handheld nut machine chuck, by providing a left clamping block, a right clamping block, a first spring and a second spring and other structures, can limit the position of the nut to be tightened and reset the left clamping block and the right clamping block, thereby achieving the effect of being easy to use while avoiding the occurrence of nut jamming.
