Description

Technical Field

[0001] The invention belongs to the technical field of clamps, and in particular relates to a welding clamp for an emergency magnetic compass lighting assembly. Background Art

[0002] The structure of a series of emergency magnetic compass lighting components is as follows: Figure 3 As shown, a connecting rod 10 and a conical spring 11 are installed on the lighting base 8. After the conical spring 11 and the connecting rod 10 are fitted together, they are inserted into the inner hole 9 on the lighting base 8, so that one end of the connecting rod 10 passes through the slender hole in the lighting base 8, and then connected to the wire 12 by welding. At present, the connecting rod and the wire are welded by pure manual welding, which is prone to problems such as skewed welding and insufficient tin melting, resulting in unstable welding quality and low welding efficiency. The specific pure manual welding has the following disadvantages: the operator must first cover the connecting rod 10 with the conical spring 11, then install them together into the lighting base 8, and then weld the wire 12 to the connecting rod 10. The connecting rod 10 covered with the conical spring 11 must be inserted into the slender hole of the lighting base 8 before it can be welded with the wire 12. Due to the elastic effect of the conical spring, one hand must press the connecting rod 10 with the conical spring 11 when welding, and the other hand can weld. In this case, the welding is easily skewed and the tin is not fully melted due to the springback force of the connecting rod with the conical spring. It takes multiple reworks to complete the welding. It takes an average of 3 minutes to complete the welding of one lighting component. It is not only time-consuming and labor-intensive, but also the welding quality is unreliable. Therefore, it is necessary to propose improvements. Summary of the invention

[0003] The technical problem solved by the present invention is to provide a welding fixture for an emergency magnetic compass lighting assembly. The present invention aims to overcome the problems of difficult welding and unreliable welding caused by the particularity of the lighting assembly structure and the rebound characteristics of the conical spring material itself.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A welding fixture for an emergency magnetic compass lighting assembly comprises a base, wherein a positioning groove for placing the lighting assembly is provided on the upper portion of the base, a fixed positioning piece for positioning one end of the lighting assembly is provided at one end of the positioning groove, and an adjustable positioning assembly is adjustably provided at the other end of the positioning groove, and one side of the adjustable positioning assembly is inserted into an inner hole in the lighting assembly to support a wiring rod installed in the hole.

[0006] As a further limitation of the above solution, the width of the positioning groove is determined according to the width of the lighting assembly and the width of the lighting assembly is gap-fitted into the positioning groove.

[0007] As a further limitation of the above scheme, the fixed positioning member adopts a cylindrical positioning pin, two of which are provided, and the two cylindrical positioning pins are evenly distributed and fixed in the width direction of the positioning groove.

[0008] To further define the above scheme, the adjustment and positioning assembly includes an adjustment block and a push pin, the adjustment block is provided with a waist-shaped hole, the adjustment block is fixed in the positioning groove by a fastening screw cooperating with the waist-shaped hole, the positioning groove is provided with a threaded hole for screwing with the fastening screw, the push pin is fixed on the inner side surface of the adjustment block, the axis of the push pin is parallel to the bottom surface of the positioning groove, and the push pin is inserted into the inner hole of the lighting base to tighten the connecting rod when in use.

[0009] As a further limitation of the above solution, the front end portion of the ejector pin for inserting into the inner hole of the lighting base is manufactured according to the structure of the inner hole.

[0010] The advantages of the present invention compared with the prior art are:

[0011] 1. This solution designs a welding fixture for the emergency magnetic compass lighting assembly, fixes the lighting assembly in the positioning groove of the welding fixture, and can tighten the connecting rod in the lighting assembly through the welding fixture, so that the connecting rod overcomes the elastic force of the conical spring and extends from the slender hole inside the lighting base, thereby facilitating the welding point connection with the wire. The use of this welding fixture overcomes the welding difficulties caused by the special structure of the lighting assembly and the rebound characteristics of the conical spring material itself in the prior art, avoids the quality risk of unreliable welding, ensures product quality, and greatly improves welding efficiency;

[0012] 2.
