An electrode cap shaping tool assembly

Abstract

This invention provides an electrode cap shaping tool assembly, including a shaping gear, connecting bearings respectively fitted at both ends of the shaping gear, a roller assembly, a shaping tool, and a cover body respectively disposed at both ends of the shaping gear and open in the middle. A cutting groove and a triangular roller groove are formed in the middle of the shaping gear. The roller assembly is placed in the roller groove, with both ends of the roller assembly abutting against the cover body, allowing the roller assembly to rotate and compress the deformed electrode cap within the roller groove. The shaping tool is installed in the cutting groove, and when the shaping gear rotates, it drives the shaping tool to cut and shape the excess part of the deformed electrode cap. This invention uses a rolling compression method to first compress the electrode cap back to its original shape with a reduced tip diameter and surface finish, and then uses a double-edged shaping tool to remove the excess part, maximizing the restoration of the electrode cap to its original shape while minimizing over-cutting.

Description

Technical Field

[0001] This utility model relates to the field of electrode cap shaping technology, specifically to a motor cap shaping tool assembly. Background Technology

[0002] An electrode cap shaping tool, as the name suggests, is used to grind the electrode cap to its original shape before welding. However, the purpose of shaping is not merely to change the shape, but to reshape the electrode cap while controlling the amount of grinding.

[0003] Currently, electrode cap shaping is achieved solely through cutting with a shaping tool. However, the shaping tool may overcut during use, making it difficult to control the precision of electrode cap shaping using only a shaping tool, which can easily damage the electrode cap. Utility Model Content

[0004] This utility model provides an electrode cap shaping tool assembly, which first extrudes the electrode cap back to its original shape and surface finish through rolling extrusion, and then removes the excess part through a double-edged shaping tool, so as to restore the electrode cap to its original shape to the greatest extent while avoiding over-cutting as much as possible.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electrode cap shaping tool assembly includes a shaping gear, connecting bearings respectively fitted at both ends of the shaping gear, a roller assembly, a shaping tool, and a cover body respectively disposed at both ends of the shaping gear and open in the middle. A tool groove and a three-shaped roller groove are formed in the middle of the shaping gear. The roller assembly is placed in the roller groove and its two ends abut against the cover body, so that the roller assembly can rotate and compress the deformed electrode cap in the roller groove. The shaping tool is installed in the tool groove and can drive the shaping tool to cut and shape the excess part of the deformed motor cap when the shaping gear rotates.

[0007] Preferably, the cover has mounting holes and roller mounting grooves. The cover can be locked onto the shaping gear with screws through the mounting holes, and the end of the roller assembly is installed into the roller mounting groove.

[0008] Preferably, the roller assembly includes a roller shaft and rollers, the rollers are mounted on the roller shaft, and both ends of the roller shaft are installed into roller mounting slots.

[0009] Preferably, the shaping tool has inwardly recessed cutting grooves on both sides of its middle section, which are adapted to the electrode cap, and form a double-edged structure.

[0010] Preferably, the device also includes a positioning component, which includes a positioning hole and a positioning pin. The positioning hole is respectively disposed on the shaping gear and the cover, and the positioning pin is installed in the positioning hole.

[0011] Compared with the prior art, the beneficial effect of this utility model is that by designing a roller assembly to extrude the electrode cap back to its original shape and surface finish, the excess part is removed by a double-edged shaping tool, so as to restore the electrode cap to its original shape to the greatest extent while avoiding excessive cutting as much as possible.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0019] Please see Figures 1 to 4As shown, an electrode cap shaping tool assembly includes a shaping gear 1, connecting bearings 2 respectively fitted at both ends of the shaping gear 1, a roller assembly 3, a shaping tool 4, and a cover 5 respectively disposed at both ends of the shaping gear 1 and open in the middle. A tool groove 12 and a roller groove 11 in the shape of a triangular shape are provided in the middle of the shaping gear 1. The roller assembly 3 is placed in the roller groove 11 and the two ends of the roller assembly 3 abut against the cover 5, so that the roller assembly 3 can rotate and compress the deformed electrode cap in the roller groove 11. The shaping tool 4 is installed in the tool groove 12. When the shaping gear 1 rotates, it can drive the shaping tool 4 to cut and shape the excess part of the deformed motor cap.

[0020] The cover 5 has mounting holes 51 and roller mounting grooves 52. The cover 5 can be locked onto the shaping gear 1 using screws through the mounting holes 51. The ends of the roller assembly 3 are installed into the roller mounting grooves 52. The roller assembly 3 includes a roller shaft 31 and rollers 32. The rollers 32 are mounted on the roller shaft 31, and both ends of the roller shaft 31 are installed into the roller mounting grooves 52. Each roller 32 has arc-shaped ends, which, during rolling, compress and shape the electrode cap.

[0021] The shaping tool 4 has inwardly recessed cutting grooves 41 on both sides of its middle section, which are adapted to the electrode cap, forming a double-edged structure. It also includes a positioning component 6, which includes positioning holes 61 and positioning pins 62. The positioning holes 61 are respectively located on the shaping gear 1 and the cover 5, and the positioning pins 62 are installed within the positioning holes 61. The positioning component 6 facilitates easier overall assembly and allows for quick positioning to the designated installation position.

[0022] This utility model is mainly installed on the electrode cap shaping machine by connecting bearing 2, and then the motor of the shaping machine drives the transmission mechanism, and finally the torque is transmitted to the shaping gear 1, and the shaping gear 1 drives the whole to rotate.

[0023] Electrode cap shaping involves shaping and cutting the welded electrode cap to remove the oxide layer from the welded contact surface. First, the electrode cap is squeezed by the roller assembly 3, causing it to deform slightly under the pressure and then rolled into shape. This process ensures that the tip diameter and surface finish of the electrode cap reach the predetermined level. Then, the shaping tool 4 removes the excess part of the deformed electrode cap, preserving its original shape.

[0024] This invention uses a roller assembly 3 to first compress the electrode cap back to its original shape and surface finish. Then, a double-edged shaping tool 4 is used to remove the excess portion, maximizing the restoration of the electrode cap to its original shape while minimizing over-cutting.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
