Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting clamps, in particular to a pipeline groove clamp. Background Art

[0002] In actual engineering applications, pipe fittings are often connected by welding. Therefore, during the pipe processing, the pipe fittings need to be beveled. The purpose is to facilitate the docking between pipes during the subsequent actual installation, thereby facilitating the welding connection process.

[0003] Pipe fittings generally include straight pipes and elbows, both of which require beveling in actual processing. However, existing pipe end beveling machines are often relatively single in function during actual use. They are generally only suitable for processing straight pipes or elbows, and are not convenient for combined processing of the two. For example, existing pipe end beveling machines, when equipped with a "V-shaped" straight pipe clamp, can clamp and fix straight pipes of different diameters, but cannot clamp and fix elbows accordingly. If the elbows need to be clamped and fixed, additional equipment needs to be purchased, which greatly increases the equipment purchase cost of the enterprise.

[0004] Therefore, a pipe beveling clamp that is modified on the basis of the existing "V-shaped" straight pipe clamp so that it can be used for clamping and fixing straight pipes and elbows respectively, thereby facilitating subsequent processing and reducing costs, is a problem that needs to be solved.

[0007] Furthermore, the "V-shaped" straight tube clamps are respectively installed on the connecting parts, the connecting parts on both sides are respectively connected to the positive and negative threaded screws and are symmetrically arranged about the middle thread transformation part of the positive and negative threaded screws, the positive and negative threaded screws are connected to the motor, and the connecting part sliding limit is installed on the machine base.

[0008] Furthermore, the front end surface of the "V-shaped" straight pipe clamp is respectively provided with mounting holes, which are detachably threadedly connected to the primary clamp through the mounting holes, and the distance between the rear side of the primary clamp and the front side of the secondary clamp is not less than 5 cm.

[0009] Furthermore, the secondary splint is directly welded and fixed on the primary splint, and the total thickness of the primary splint and the secondary splint is not less than 5 cm.

[0010] Furthermore, there is a gap between the secondary splint and the primary splint, and the total thickness of the primary splint, the gap and the secondary splint is not less than 5 cm.

[0011] Furthermore, the inner side of the arc-shaped clamp is evenly provided with convex ridges, and the convex ridges match the outer side wall of the elbow.

[0012] Furthermore, the angle of the arc corresponding to the arc-shaped clamping opening ranges from 90° to 180°.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1-5 As shown, in the present embodiment, a base 1 is provided in the bevel clamp, a slide groove 11 is provided on the base 1, a connecting member 3 is installed through the slide groove 11 and a transmission mechanism 2, wherein the transmission mechanism 2 includes a forward and reverse thread screw 21, the forward and reverse thread screw 21 is connected to the motor, there are two connecting members 3 and they are symmetrically arranged about the thread transformation part in the middle of the forward and reverse thread screw 21, and "V-shaped" straight pipe clamps 4 are respectively fixedly installed through the two connecting members 3, and the "V-shaped" straight pipe clamps 4 can be used for clamping and fixing the straight pipe 6.

[0025] Mounting holes 41 are respectively provided on the front end surfaces of the two "V-shaped" straight pipe clamps 4, and elbow clamps 5 are threadedly installed through the mounting holes 41. The elbow clamps 5 include a primary clamp 51 and a secondary clamp 52. In this embodiment, the secondary clamp 52 is fixedly installed on the primary clamp 51, and a gap is formed between the primary clamp 51 and the secondary clamp 52. Arc-shaped clamps 53 are provided in the primary clamp 51 and the secondary clamp 52, and convex ridges 54 are provided on the inner side of the arc-shaped clamp 53, and the elbow 7 is clamped and fixed by the elbow clamp 5.

[0026] Example 2

[0027] like Figure 5-6 As shown, compared with Embodiment 1, in this embodiment, the secondary clamping plate 52 is directly welded and fixed on the primary clamping plate 51 .

[0028] The principle of this utility model is:

[0029] The utility model can respectively clamp and fix the straight pipe 6 and the elbow 7 when in use. If the straight pipe 6 needs to be clamped and fixed during use, and then the beveling operation is performed, there is no need to install the elbow clamp 5, and only the "V-shaped" straight pipe clamp 4 is retained.

[0030] During specific use, a lifting device is used to lift the straight tube 6 to be processed and lower it between two "V-shaped" straight tube clamps 4. Driven by the motor, the positive and negative screws 21 rotate, and the two "V-shaped" straight tube clamps 4 approach each other. During the process, the position of the straight tube 6 is adjusted to achieve a stable clamping process for the straight tube 6. During this process, the machine base 1, slide groove 11, transmission mechanism 2, connector 3 and "V-shaped" straight tube clamp 4 involved are existing mature equipment and technologies, which are not difficult to understand for technicians in this field and will not be described in detail.

[0031] When the elbow 7 needs to be clamped and fixed, the elbow clamp 5 is installed on the two "V-shaped" straight pipe clamps 4 to achieve the clamping and fixing of the elbow 7. The whole clamping process is similar to the clamping process of the straight pipe 6 and will not be repeated here.

[0032] For the elbow clamp 5 of the utility model, in order to ensure the stability of the elbow clamping, the primary splint 51 and the secondary splint 52 need to have a certain thickness. In Example 1, the distance between the primary splint 51 and the secondary splint 52 is increased, and the stable clamping of the elbow 7 can be achieved through the two splints. At this time, there is no special requirement for the thickness of the plates of the primary splint 51 and the secondary splint 52, as long as stable use can be guaranteed; the distance between the primary splint 51 and the secondary splint 52 is reasonably set according to the actual production. Generally, it is greater than 5cm to ensure the stability of the elbow clamping and fixing; and for Example 2, the secondary splint 52 is directly welded and fixed on the primary splint 51. At this time, the primary splint 51 and the secondary splint 52 are required to have a certain thickness, and the stability of clamping is ensured by this thickness. The sum of the thicknesses of the two is generally maintained at more than 5cm.

[0033] In the utility model, for the arc-shaped clamp 53, in Examples 1-2, the arc-shaped clamp 53 is semicircular, and two arc-shaped clamps 53 form a full circle. In actual use, it can only be used to clamp and fix the elbow 7 corresponding to the circle diameter size. However, there is no doubt that if the angle range of the arc corresponding to the arc-shaped clamp 53 is less than 180°, it is possible to clamp and fix elbows 7 of different diameters, which is more convenient to use. At the same time, a convex rib 54 is also provided on the inner side of the arc-shaped clamp 53 to improve the stability of clamping.
