Description

Technical Field

[0001] The utility model relates to the technical field of workpiece welding positioning auxiliary tools, in particular to a welding positioning tool for a lamp holder stamping and drawing part. Background Art

[0002] A street lamp generally consists of a base, a lamp pole, a lamp holder, a lamp shade, etc. A common lamp holder is generally T-shaped in appearance. The two ends of the T-shaped lamp holder are equipped with lamp shades, and the lamp shades are equipped with lamps for lighting both sides of the street lamp. In the actual production of lamp holders, two lamps need to be connected as shown in the following figure. Figure 4 The stamped and drawn parts 4 shown are welded as shown in the attached Figure 5 The finished lamp holder welding product 5 shown in the figure, the stamped and drawn part 4 includes a short tube 41 and a long tube 42, which are combined into a T-shaped structure, and in order to improve the structural stability of the finished product, in at least one stamped and drawn part 4, it is necessary to set a crescent plate 43 in the short tube 41, and set at least two crescent plates 43 in the long tube 42. When the number exceeds two, two of them are respectively set at one end close to the position where the lampshade is to be installed, and the setting position of the remaining crescent plates 43 is determined according to the length of the long tube 42 extending to the two ends of the short tube 41.

[0003] However, there are some problems in the production of stamped and drawn parts 4: the existing stamped and drawn parts 4 are processed by drawing technology, and drawing is a type of stamping process, which is to extend the metal sheet along the stamping direction. After the stamped and drawn parts 4 are drawn and stamped from a sheet into a predetermined shape, they need to be cut along the edges. However, under the current process level, the edges of the stamped and drawn parts 4 will inevitably rebound outward after cutting, which will greatly affect the accuracy and efficiency of the subsequent welding of the two stamped and drawn parts 4, and may even cause the workpiece to be unable to be cut normally. The precision deviation of the cut workpiece is very large and cannot meet the use requirements. Therefore, a welding positioning tool is required to limit the edges of the stamped and drawn parts 4 inward for welding. Utility Model Content

[0004] In view of the above-mentioned defects, the utility model provides a welding positioning tool for the stamped and drawn parts of the lamp holder. The lower positioning unit and the upper positioning unit can jointly limit the stamped and drawn parts stably in the middle, thereby facilitating the welding of the two stamped and drawn parts. The upper positioning unit can remain in the lamp holder as a part of the lamp holder after welding, thereby improving the structural strength of the lamp holder.

[0005] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0006] A welding and positioning tool for a lamp holder stamping and drawing part, comprising a bottom plate and:

[0007] The lower positioning unit is arranged at the upper end of the bottom plate, and includes a first vertical plate, a third vertical plate and at least two second vertical plates. The upper ends of the first vertical plate and the second vertical plate are both provided with semicircular grooves. The semicircular groove of the first vertical plate is used to carry the short tube, and the semicircular groove of the second vertical plate is used to carry the long tube. The third vertical plate includes three sub-plates in a circumferential array, and one end of each sub-plate is respectively provided with a pie-shaped groove. One of the three pie-shaped grooves is used to carry one end of the outer peripheral side of the long tube, and the other two are used to carry two connecting parts of the long tube and the short tube.

[0008] The upper positioning unit is assembled on the upper end of the stamped and drawn part placed in the lower positioning unit, and includes a first plug-in piece and at least two second plug-ins. The first plug-in piece matches the semicircular groove of the first vertical plate and is assembled on the inner side of the crescent plate of the short tube. Each second plug-in piece matches the semicircular groove of the second vertical plate and is respectively assembled on one side of each crescent plate of the long tube. Square grooves are opened on the upper ends of the first plug-in piece and the second plug-in piece. The upper positioning unit also includes a T-shaped tube fixedly connecting the square grooves.

[0009] Furthermore, a group of first jacks is opened on one side of the upper end surface of the bottom plate, several groups of second jacks are opened on both ends of the upper end surface of the bottom plate, and three groups of third jacks are opened on the upper end surface of the bottom plate, which are located on one side of the first jacks and arranged in a circular array.

[0010] Furthermore, a plurality of plug blocks are provided at the lower ends of the first vertical plate and the second vertical plate. The plug blocks at the lower ends of the first vertical plate are matched with the first plug holes respectively, and the plug blocks at the lower ends of the second vertical plate are matched with the second plug holes respectively.

[0011] Furthermore, the lower end is provided with a plurality of plug blocks respectively matching with the third plug holes.

[0012] Furthermore, both ends of the first vertical plate and the second vertical plate are respectively provided with extension plates, and the outer ends of each branch plate are also respectively provided with extension plates.

[0013] Furthermore, the three branch plate ends have a common edge.

[0014] The beneficial effects of this technical solution are:

[0015] 1. The lower positioning unit includes a plurality of semicircular grooves and pie-shaped grooves, which can limit the stamping and drawing parts from the bottom to reduce the outward rebound of the edge of the stamping and drawing parts. The first plug-in piece and the second plug-in piece of the upper positioning unit press the stamping and drawing parts downward from the top respectively. In addition, the weight of the T-tube enables the stamping and drawing parts to be better pressed on the lower positioning unit to improve the positioning effect. Under the joint action of the lower positioning unit and the upper positioning unit, the stamping and drawing parts can be stably limited, which can improve the accuracy of welding and facilitate welding.

[0016] 2. After welding is completed, the upper positioning unit can be left in the lamp holder as a part of the lamp holder, and the structure of the T-tube, the first insert and the second insert can provide support inside the lamp holder, thereby improving the structural strength of the lamp holder and improving product quality.
