Figure 1 As described above, to prevent the spring from falling, installing the spring in the brush holder is a complicated process. In order to improve production efficiency, it is necessary to provide an automated device for installing the brush holder spring. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automated device for installing a brush holder spring in view of the above-mentioned deficiencies in the prior art, thereby realizing the automated installation of the spring in the brush holder and improving production efficiency.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an automated equipment for installing a brush holder spring, comprising a frame, a work surface being provided on the frame, and characterized in that: a base plate is provided on the work surface, an upper template which can reciprocate in a vertical direction is provided on the base plate, a riveting head for riveting the brush holder is installed on the upper template, at least one riveting assembly is provided in the riveting head, a lower template which can move directly below the riveting head is provided on the base plate, a brush holder positioning plate for fixing the brush holder fixing plate, and at least one spring positioning assembly for fixing the spring in the brush holder are provided on the lower template, the brush holder positioning plate is located at the center of the lower template, and the spring positioning assembly is arranged on one side of the brush holder positioning plate.

[0005] The present invention with the above characteristics: the brush holder assembly is placed on the brush holder positioning plate, the worker places the spring in the brush holder, the spring positioning assembly confines the spring in the brush holder, the upper template drives the riveting head to descend until the riveting assembly rivets the card at the end of the brush holder, and the riveting assembly cooperates with the spring positioning assembly to install the spring in the brush holder. By using this equipment, the automatic installation of the spring in the brush holder is realized, thereby improving production efficiency.

[0006] A further configuration of the present invention is that the spring positioning assembly includes a spring cylinder, a push rod connected to the output end of the spring cylinder, and a guide block, one end of the push rod passes through the guide block and is provided with a spring guide needle that can be sleeved with the spring, and the spring cylinder and the guide block are both fixedly mounted on the lower template.

[0007] The present invention has the above characteristics: the spring cylinder drives the push rod to move toward the guide block, compressing the spring into the brush holder, thereby assisting in the installation of the spring; a spring guide pin is provided at the end of the push rod to be sleeved with the spring, which can better apply pressure to the spring and prevent the spring from deflecting, tilting, or falling during the compression process; a guide block is provided to support and guide the push rod, thereby preventing the push rod from breaking due to one end being left hanging in the air.

[0008] A further configuration of the present invention is: the riveting head includes a mounting block, the riveting assembly includes a bidirectional sliding cylinder vertically mounted on the side of the mounting block, the bidirectional sliding cylinder includes a cylinder body, a cylinder guide groove and two cylinder sliders arranged in the cylinder guide groove, a riveting block is fixedly connected to the cylinder slider, the riveting block includes a connecting portion fixedly connected to the cylinder slider, a riveting portion arranged perpendicular to the connecting portion, and the riveting portions of the two riveting blocks are arranged opposite to each other.

[0009] The present invention has the above-mentioned characteristics: the bidirectional slide cylinder can simultaneously drive the two cylinder sliders to move toward or away from each other, and the cylinder sliders drive the riveting blocks to approach each other to perform riveting on the brush holder. After the riveting is completed, the riveting blocks move away from each other, ensuring that riveting is performed on both sides of the brush holder at the same time, thereby ensuring the processing quality.

[0010] A further configuration of the present invention is that one end of the riveting portion that cooperates with the brush holder is a tip, and its cross section is triangular, and the upper pressing surface and the lower pressing surface of the tip abut against the card of the brush holder to rivet the brush holder.

[0011] The present invention has the above characteristics: the upper pressing surface and the lower pressing surface of the tip respectively abut against the card of the brush holder, and as the slider approaches the brush holder, the card is pressed toward the opposite side to form a barrier against the spring; the tip is set to have a triangular cross-section to increase the riveting pressure on the card.

[0012] The present invention is further configured as follows: the end face of the mounting block is provided with a brush holder solid block for maintaining the shape of the brush holder, the side of the brush holder solid block facing the brush holder is provided with a groove for the brush holder to be embedded, and the two side walls of the groove are in contact with the side faces of the brush holder.

[0013] The present invention has the above characteristics: when the mounting block is pressed down along with the upper template, the brush holder is embedded in the groove, and the two side walls of the groove are in contact with the two side surfaces of the brush holder, thereby preventing the two side surfaces of the brush holder from being deformed due to the riveting action of the riveting part.

[0014] A further configuration of the present invention is that a vertically arranged push rod guide plate is provided on the cylinder body, and one end of the push rod guide plate is provided with a guide channel for the push rod to pass through.

[0015] The present invention has the above characteristics: the push rod is driven by the spring cylinder and the lower end passes through the guide block and enters the brush holder. The push rod guide plate arranged between the guide block and the brush holder guides the push rod, ensuring the assembly accuracy while extending the service life of the push rod.

[0016] A further arrangement of the present invention is that: two parallel slide rails are provided on the base plate, a slider adapted to the slide rails is provided on the lower end surface of the lower template, a slide groove is provided on the base plate between the two slide rails, a link plate is installed in the slide groove, one end of the link plate is fixedly connected to the lower template, and a chain plate cylinder is provided under the slide groove for driving the link plate to move back and forth along the slide groove.

[0017] The present invention with the above-mentioned characteristics: after the brush holder assembly is placed in the brush holder positioning plate by the worker, the chain plate cylinder drives the lower template to move to the bottom of the riveting head to wait for riveting. By setting the lower template to be movable, the lower template is on the outside when loading, which is convenient for workers to load materials and can avoid injuries caused by sudden downward pressure of the riveting head, thereby improving the safety factor of production.
