Description
Technical Field
The invention belongs to the technical field of photoelectric measurement, and particularly relates to a hooping structure of a cylindrical cable joint of a steel strip grating ruler.
Background
In the fields of precision measurement and displacement control, a grating ruler is mostly adopted as a measuring means. The grating ruler is the most economical and applicable technical equipment for high-precision measurement, so that the grating ruler is widely applied to the technical fields of engineering related to measurement, such as machine tools, displacement control consoles and the like. The grating ruler generally comprises a glass grating ruler and a steel belt grating ruler. When the length of the grating ruler exceeds 4 meters, a steel strip grating ruler is generally adopted. The cable shield layer of the steel strip grating ruler is connected with the shell, and the cable and the shell are fixed through a metal joint. The metal joint is firstly sleeved on the cable wire which is stripped from the insulating protective layer and leaks out of the shielding wire, and the metal joint is fixed on the shell after being hooped by the wire pressing pliers. The metal joint is mainly cylindrical and cylindrical with an opening.
In the method of tightening a cylindrical metal joint or a cylindrical metal joint with an opening, a terminal crimping pliers or other special tools are generally adopted. If a mechanism which is circular after being tightened is desired, the tightening structure is two semicircles with the same radius and smaller than the radius of the cable wire, and a cylindrical metal joint or a cylindrical metal joint with an opening is tightened through the processes from separation to closing of the two semicircles.
The problem is that metal is extruded and accumulated at the joint of the two semi-circles in the closing process of the two semi-circles, and the metal is extruded and accumulated towards the outer side. Especially, when the cylindrical metal joint is used, the radius of the cylinder is reduced in the tightening process, redundant metal is extruded outwards, and metal accumulation at the semicircular joint is very obvious, so that an ideal cylindrical shape cannot be formed after tightening, the fixation on the shell is not facilitated, and the appearance of a product is also influenced.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a hooping structure of a cylindrical cable joint of a steel strip grating ruler, which solves the problem that an ideal cylindrical shape can be formed after a cylindrical metal joint is hooped.
The technical scheme adopted by the invention for solving the technical problem is as follows:
A structure of cramping of steel band grating chi cable conductor cylinder joint, this structure of cramping includes: the first tightening wheel, the spring structure and the second tightening wheel; the two ends of the spring structure are respectively fixed on the inner sides of the first tightening wheel and the second tightening wheel, and the first tightening wheel and the second tightening wheel are identical in structure.
Preferably, the spring structure is a rectangular spring structure.
Preferably, the center of the first tightening wheel is provided with a hole, and a plurality of grooves are uniformly distributed on the outer edge of the first tightening wheel.
Preferably, the number of the grooves is 5.
The invention has the beneficial effects that: the invention can form an ideal cylinder after the cylindrical metal joint is hooped, and the cylindrical structure is more beneficial to connecting the shielding layer to shield signals, more beneficial to fixing the cable to the shell and more beautiful in structure. Meanwhile, the invention has simple structure, low cost and flexible and convenient operation.

In the figure: 1. the cable comprises a cable body, 11, a rubber protective layer, 12, a shielding layer, 2, a tightening structure, 21, a first tightening wheel, 211, a groove, 212, a cable through hole, 22, a rectangular spring structure, 23, a second tightening wheel, 3 and a metal joint.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
A structure for hooping a cylindrical cable joint with a steel strip grating ruler is to peel a rubber protective layer 11 of a cable 1 to leak a shielding layer 12 as shown in figure 1, then to sleeve a cylindrical metal joint 3 at a position approximately as shown in figure 1, and finally to hoop through the hooping structure of the invention.
As shown in fig. 2, a tightening structure 2 for a cylindrical cable joint of a steel strip grating ruler comprises: a first takeup wheel 21, a spring structure and a second takeup wheel 23; the two ends of the spring structure are respectively fixed at the inner sides of the first tightening wheel 21 and the second tightening wheel 23, in this embodiment, the spring structure is a rectangular spring structure 22, and the two ends of the rectangular spring structure 22 are fixed at the inner sides of the first tightening wheel 21 and the second tightening wheel 23 through welding.
The first tightening wheel 21 and the second tightening wheel 23 are identical in structure. As shown in FIG. 3, a plurality of grooves 211 are uniformly distributed on the outer circumference of the tightening wheel, in this embodiment, the number of the grooves 211 is 5, which just fits the number of fingers of one hand. A cable through hole 212 is formed in the center of the tightening wheel, so that the cable 1 can pass through the tightening wheel and enter the rectangular spring structure 22.
During operation, the cable 1 sleeved with the cylindrical metal connector 3 is placed in the cable through holes of the first tightening wheel 21, the rectangular spring structure 22 and the second tightening wheel 23 through the cable through hole 212 at a proper position, the first tightening wheel 21 and the second tightening wheel 22 are held by two hands, the rectangular spring structure 22 is compressed by the two hands, the tightening wheel 21 and the tightening wheel 22 are rotated towards the direction of tightening the rectangular spring structure 22, at the moment, the rectangular spring structure 22 is compressed, the inner diameter of the rectangular spring structure 22 is tightened, and then the cylindrical metal connector 3 sleeved on the cable 1 is tightened and contracted. Because the inner diameter of the rectangular spring structure 22 is round and continuously reduced in the processes of being pressed and rotating and contracting, the radius of the cylindrical metal joint 3 is continuously reduced, and redundant metal cannot be extruded outwards, so that the redundant metal can only be extruded inwards and accumulated on the inner side, and the outer circle profile of the cylindrical metal joint 3 is kept round all the time.
