Description

Technical Field

[0001] The utility model relates to the technical field of glass reactor processing, in particular to a glass flange welding fixture and a welding device. Background Art

[0002] In the process of making glass reactors, especially glass covers of multi-port glass reactors, welding of glass flanges and glass cover blanks with holes is an indispensable and important process. Traditionally, the welding method of glass flanges and glass cover blanks is as follows: the operator holds a sleeve rod to put on the glass flange, and uses a welding gun to heat and melt the mouth of the glass flange, and then first sticks the glass flange to the hole on the surface of the glass cover, and then performs local repair and angle adjustment at the joint of the two. This method is not only time-consuming and labor-intensive, but also the welding part is not smooth and beautiful, and the technical requirements of the operator are also extremely high; in addition, during welding, the angle of the glass flange is easy to deviate, and if it is adjusted later, it is easy to damage the glass flange.

[0003] At present, some manufacturers have realized semi-automatic welding of glass flanges, such as patent application CN111545144A, a method for manufacturing a double-layer glass reactor, which can directly use the left and right chucks of the glass machine tool for welding, that is, first clamp the glass cover blank on the left chuck, clamp the glass flange on the right movable chuck, and then move the right chuck for direct welding. This not only reduces the labor intensity of operators to a certain extent and improves welding efficiency, but also makes the welding point smooth and beautiful, and the technical requirements for operators are not high.

[0004] However, the existing technology still has the problem that the angle of the glass flange is easy to deviate. If fine-tuning is performed after the deviation, the glass flange is easily damaged, which seriously affects the welding efficiency of the glass flange and even the production efficiency of the glass cover. At the same time, due to the limitations of the chuck, the existing technology is often only applicable to the welding of the glass flange that is coaxial with the glass cover blank, and does not ensure that it is applicable to the welding of non-coaxial glass flanges, and its practicality is general.

[0005] Therefore, a new technical solution is needed to solve the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to provide a glass flange welding fixture and a welding device to solve the technical problems that the angle of the glass flange in the prior art mentioned in the above background technology is still easy to deviate, and if fine-tuning is performed after the deviation, it is very easy to cause damage to the glass flange, which seriously affects the welding efficiency of the glass flange and even the production efficiency of the glass cover, and the prior art often does not ensure that it is suitable for welding the glass flange that is not coaxial with the glass cover blank, and has general practicality.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A glass flange welding fixture comprises a chuck and a main shaft horizontally clamped on the chuck, the front end of the main shaft is rotatably connected to an adjusting rod which is perpendicular to it and has an adjustable height, the upper end of the adjusting rod is swung up and down and is connected to a sleeve rod for sleeved glass flange and the sleeve rod can be parallel to the main shaft, the main shaft is also provided with a rotating sleeve which cooperates with it, and the sleeve rod is also provided with an angle adjustment sleeve which cooperates with it.

[0009] Furthermore, the angle adjustment sleeve is composed of an adjusting outer sleeve and an adjusting plate located below the adjusting outer sleeve, which are welded in a T-shape. The adjusting outer sleeve is mounted on the outer side of the rear end of the sleeve rod, and a top screw III for locking the sleeve rod is also pierced on the top of the adjusting sleeve. A connecting plate with an inverted U-shaped structure with an opening facing away from the adjusting rod is welded on the upper end of the adjusting rod. The connecting plate is located below the adjusting outer sleeve and both end portions of the connecting plate close to the adjusting outer sleeve are arranged in an arc shape. The adjusting plate extends into the opening of the connecting plate and is rotatable relative to the connecting plate. An adjusting screw for adjusting the rotation angle of the adjusting plate and locking the adjusting plate is pierced on the side wall of the connecting plate.

[0010] Furthermore, the rotating sleeve is composed of a transverse rotating sleeve and a longitudinal rotating sleeve welded in a T-shape, the transverse rotating sleeve and the longitudinal rotating sleeve are both hollow annular structures and the transverse rotating sleeve is horizontally arranged, the front end end of the main shaft extends into the interior of the transverse rotating sleeve, and the transverse rotating sleeve is also radially penetrated with a top screw I for locking the main shaft, the adjusting rod passes through the longitudinal rotating sleeve and the upper and lower ends of the adjusting rod are both extended out of the longitudinal rotating sleeve, and the longitudinal rotating sleeve is also radially penetrated with a top screw II for locking the adjusting rod.

[0011] In addition to the above technical solutions, the utility model also provides a welding device, including the above-mentioned glass flange welding fixture.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a chuck of a glass lathe, and is provided with a main shaft, an adjusting rod, and a sleeve rod for sleeve-connecting a glass flange. The main shaft is horizontally clamped by the chuck, and the adjusting rod is vertically connected to the front end of the main shaft so as to be adjustable in height and rotatable in the circumferential direction, and the sleeve rod is connected to the upper end of the adjusting rod so as to be swingable up and down and parallel to the main shaft. The main shaft, the adjusting rod, the sleeve rod and the chuck cooperate with each other to realize multi-degree-of-freedom position adjustment of the glass flange on the sleeve rod relative to the hole of the glass cover blank before welding operation, including angle, that is, by rotating the adjusting rod, the welding position in various directions can be conveniently adjusted, and by adjusting the height of the adjusting rod, the center distance can be controlled. After the angle adjustment is realized by swinging the sleeve rod up and down, a welding gun is used for heating, melting and butting. During the whole process, not only does the operator not need to hold the sleeve rod for docking, the labor intensity is low, the welding place is smooth and beautiful, the technical requirements for the operator are low, and the glass flange can be accurately welded at one time without the need for other adjustments including angles. This fully ensures the welding effect of the glass flange and avoids damage to the glass flange due to fine-tuning after welding, greatly improves the welding efficiency of the glass flange, and ultimately greatly improves the production efficiency of the glass cover; in addition, the position of the glass flange relative to the hole of the glass cover blank can be adjusted with multiple degrees of freedom including angles, which also makes the utility model applicable to the welding of glass flanges that are not coaxial with the glass cover blank, that is, it is applicable to the processing of multi-opening glass covers, which greatly improves the overall practicality.

[0014] 2. The rotation and height adjustment of the adjustment rod in the utility model are realized by the rotating sleeve, and the up and down swing of the sleeve rod in the utility model is realized by the angle adjustment sleeve. The operation of the horizontal rotating sleeve, the longitudinal rotating sleeve, and the angle adjustment sleeve only requires the corresponding top screws or adjusting screws to cooperate to adjust the tightness. The entire process of adjusting the position of the glass flange is extremely convenient and fast, and ultimately the welding efficiency of the glass flange and even the production efficiency of the glass cover can be further improved.

[0015] 3. The angle adjustment sleeve in the utility model is composed of an adjustment outer sleeve and an adjustment plate located below the adjustment outer sleeve, which are welded in a T-shape. The adjustment outer sleeve in the utility model is installed on the outer side of the rear end of the sleeve rod, and a top screw III for locking the sleeve rod is provided on the top of the adjustment outer sleeve. This allows the user to adapt to glass flanges of different specifications by simply twisting the top screw III and replacing different sleeve rods, which further improves the overall practicality.
