Abstract
The utility model relates to a swing structure for a jaw of a winding machine. The swing structure comprises a pressing sleeve, a sliding sleeve, a jaw and a spring, wherein a groove is coaxially formed at the middle part of the pressing sleeve and the sliding sleeve, a pressure spring is coaxially mounted in the groove, the jaw is fixedly arranged at the top of the sliding sleeve, a screw hole is formed at the middle part of the sliding sleeve, the screw hole is formed in the same axial direction with the groove at the middle part of the pressing sleeve and the sliding sleeve, an unthreaded hole is coaxially formed in the position of the pressing sleeve, which corresponds to the screw hole, an unthreaded rod is coaxially sheathed on the unthreaded hole, an external thread is arranged at one end of the unthreaded rod, the unthreaded rod extends into a bolt hole for fastening, and the other end of the unthreaded rod is positioned outside the unthreaded hole of the pressing sleeve. The swing structure provided by the utility model can prevent reducing the wall thickness of the connection part of the sliding sleeve and the jaw so as to enable the global stress of the sliding sleeve to be more uniform to prevent the fracture of the connection part of the sliding sleeve and the jaw, thereby ensuring the stability of parts in production processes.
Description
Technical field
The utility model belongs to metallurgical plate manufacture field, relates to coiling machine, especially a kind of swinging structure for coiler jaw.
Background technology
At present, known pickling lines rolling coiler jaw mechanism be mostly to adopt sliding sleeve (jaw connected body) and spring mechanism band movable clamp port bar reciprocating, but due to jaw and sliding sleeve small volume and installing space limited, often in narrow space, need to be bolted and other stopping means carry out spacing to it, it is moved back and forth by sliding sleeve band movable clamp port in the stroke of regulation, but tend to occupy the certain wall thickness of sliding sleeve owing to being bolted, so just make to slide in motion process and not only to need to bear nipper pressure but also need to bear the impulsive force in motion process, and because wall thickness has reduction to a certain degree, the position that often occurs to install with jaw or be connected occurs that slight crack even ruptures.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of simple in structure, use the stable swinging structure for coiler jaw.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of swinging structure for coiler jaw, comprise gland, sliding sleeve, jaw and spring, at gland and sliding sleeve middle part, be coaxially shaped with groove, in this groove, be coaxially installed with stage clip, at sliding sleeve top, be fixed with jaw, in sliding sleeve bottom, be provided with a screw, the groove at this screw and gland and sliding sleeve middle part is coaxial, on the gland position corresponding with this screw, be coaxially shaped with a unthreaded hole, coaxial package one polished rod on this unthreaded hole, this polished rod one end is shaped with external screw thread and stretches into bolt hole and gives fasteningly, and the described polished rod other end is positioned at outside gland unthreaded hole.
And, described in polished rod one end of being positioned at outside gland unthreaded hole by nut, give fastening.
And, between described gland and sliding sleeve, leave gap.
Advantage of the present utility model and good effect are:
The utility model through repeatedly experiment to sliding sleeve force analysis, to being provided with bolt hole at sliding sleeve bottom assigned address, on this bolt hole, engagement is fixedly mounted with the polished rod that an end is shaped with screw thread, this polished rod other end is packed in gland outside by nut, guaranteed thus and gland between the free travel of sliding sleeve, the most key is the wall thickness of avoiding reducing sliding sleeve and jaw connecting portion, make sliding sleeve whole stressed more even, avoid sliding sleeve and the fracture of jaw connecting portion, thereby guaranteed the stability of parts in production process, reduced the trouble point of equipment, reduced equipment downtime, avoided the waste of the resources of production, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation (sectional structure).
The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
For a swinging structure for coiler jaw, comprise gland 2, sliding sleeve 4, jaw 3 and spring 6, at gland and sliding sleeve middle part, be coaxially shaped with groove (not label), in this groove, be coaxially installed with stage clip, at sliding sleeve top, be fixed with jaw.
Innovative point of the present utility model is:
In sliding sleeve bottom, be provided with a screw, the groove at this screw and gland and sliding sleeve middle part is coaxial, on the gland position corresponding with this screw, be coaxially shaped with a unthreaded hole, coaxial package one polished rod 1 on this unthreaded hole, this polished rod one end 7 is shaped with external screw thread and stretches into bolt hole and gives fastening, it is outside and by nut, give fasteningly that the polished rod other end is positioned at gland unthreaded hole, leaves gap, thus to the reciprocating stroke of sliding sleeve between gland and sliding sleeve.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
Claims (3)
1. the swinging structure for coiler jaw, comprise gland, sliding sleeve, jaw and spring, at gland and sliding sleeve middle part, be coaxially shaped with groove, in this groove, be coaxially installed with stage clip, at sliding sleeve top, be fixed with jaw, it is characterized in that: in described sliding sleeve bottom, be provided with a screw, the groove at this screw and gland and sliding sleeve middle part is coaxial, on the gland position corresponding with this screw, be coaxially shaped with a unthreaded hole, coaxial package one polished rod on this unthreaded hole, this polished rod one end is shaped with external screw thread and stretches into bolt hole and gives fastening, the described polished rod other end is positioned at outside gland unthreaded hole.
2. the swinging structure for coiler jaw according to claim 1, is characterized in that: described in polished rod one end of being positioned at outside gland unthreaded hole by nut, give fastening.
3. the swinging structure for coiler jaw according to claim 1, is characterized in that: between described gland and sliding sleeve, leave gap.
