Description

Technical Field

[0001] The utility model relates to the technical field of terminal processing equipment, in particular to a terminal chamfering processing device. Background Art

[0002] Terminals play a crucial role in electrical connectors, and their quality directly impacts the safety and reliability of electrical equipment. Chamfering is a necessary process in terminal processing, especially for tubular terminals. It not only impacts the terminal's appearance but also, more importantly, plays a crucial role in preventing damage to the wire insulation and improving connection reliability.

[0003] Traditional methods for chamfering tubular terminals typically involve separate chamfering of the inner and outer edges of one terminal. This method requires multiple clamping steps, which is not only inefficient but also increases the potential for machining errors. Furthermore, because the angle between the tool and the terminal is fixed during chamfering, a tool head with a specific angle is often required to achieve a good fit. This places high demands on tool head manufacturing and increases the complexity of tool head grinding. Summary of the Invention

[0004] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a terminal chamfering processing device to solve the problems that the existing equipment cannot simultaneously chamfer the inside and outside and the tool installation is unreasonable.

[0005] The technical solution of the present utility model includes a feeding mechanism, a positioning mechanism and a processing mechanism. The feeding mechanism is connected to the positioning mechanism and supplies a terminal to be processed to the positioning mechanism. The positioning mechanism is clamped on the outer surface of the terminal to be processed. The processing mechanism has two groups and is respectively arranged on both sides of the positioning mechanism. The processing mechanism includes a rotating shaft and a feed seat that drives the rotating shaft close to the terminal to be processed. Two tools are installed on the rotating shaft. The two tools are arranged at radial positions of the rotating shaft and the central angle formed between the two tools is an obtuse angle. The two tools are respectively aligned with the inner edge and outer edge of the axial side of the terminal to be processed.

[0006] By adopting the above technical solution, since the device can simultaneously chamfer the inner and outer edges of the terminal, the steps required for multiple clamping in the traditional method are reduced, and the processing efficiency is significantly improved; the internal and external chamfers are completed by one clamping, which avoids the position deviation caused by multiple clamping, thereby reducing the processing error and improving the product qualification rate; in addition, since the central angle between the two tools is an obtuse angle, the tools can be reasonably arranged even in a limited space, and the tool head part can better fit the inner and outer edges of the terminal, reducing the requirements for special angles of the tool, simplifying the design and manufacturing process of the tool, and reducing costs.

[0007] In one possible design, the feeding mechanism includes a fixed jaw, a movable jaw, a feeding channel and a driving member. The fixed jaw and the movable jaw are arranged relative to each other and when combined, form a clamping hole that is adapted to the outer surface of the terminal to be processed. The driving member drives the fixed jaw and the movable jaw to move from the feeding channel to the positioning mechanism; the fixed jaw is fixedly mounted on the output shaft of the driving member, and the movable jaw is hinged to the fixed jaw; the fixed jaw is fixedly provided with a fixed mounting arm, and a compression spring is installed between the fixed mounting arm and the movable jaw, and the two ends of the compression spring are respectively against the fixed mounting arm and the movable jaw.

[0008] With the above design, the terminal to be processed can be accurately clamped through the cooperation of the fixed clamping jaw and the movable clamping jaw, and the clamping hole formed when the two are combined adapts to the outer surface of the terminal, ensuring the stability and accuracy of the terminal during the processing, which helps to improve the processing accuracy; and the elastic force of the compression spring is used on the movable clamping jaw to make the movable clamping jaw elastically clamp the terminal. When the terminal reaches the specified position, the positioning mechanism only needs to fix the terminal, and the movable clamping jaw automatically releases the terminal when returning to its position, so that it is smoothly transferred to the positioning mechanism. This process does not require an additional power source, which simplifies the operation process.

[0009] In one possible design, the positioning mechanism includes a fixed clamping block, a movable clamping block, and a cylinder that drives the movable clamping block to merge with the fixed clamping block. The movable clamping block is fixedly mounted on the output shaft of the cylinder. The movable clamping block and the fixed clamping block are arranged opposite to each other and when the two are merged, a positioning hole is formed that is adapted to the outer surface of the terminal to be processed.

[0010] With the above design, a reliable clamping force is provided through the automatic control of the cylinder, which can easily realize the automatic positioning and clamping of the terminal, ensuring the precise position of the terminal during the processing.

[0011] In one possible design, guide channels are provided in the fixed clamping block and the movable clamping block. The clamping positions of the fixed clamping jaw and the movable clamping jaw are respectively in the shape of plates. The guide channels are adapted to the thickness of the fixed clamping jaw and the movable clamping jaw. After the fixed clamping jaw and the movable clamping jaw are inserted into the guide channels, the movable clamping block pushes the terminal into the positioning hole.

[0012] With the above design, the guide channel not only guides the moving trajectory of the fixed clamping jaw and the movable clamping jaw, but also provides a smooth guide path, which enables the terminal to pass smoothly during the transfer from the feeding mechanism to the positioning mechanism, reduces jamming and resistance, improves the smoothness of transfer, reduces the deviation of the terminal during the transfer process, and ensures that the terminal can accurately enter the processing position.

[0019] The feeding mechanism 1 comprises a fixed jaw 11, a movable jaw 12, a feeding channel 13 and a driving member (not shown in the figure), the fixed jaw 11 and the movable jaw 12 are oppositely arranged and form a clamping hole fitting the outer surface of the terminal 4 when combined, and the driving member drives the fixed jaw 11 and the movable jaw 12 to move from the feeding channel 13 to the positioning mechanism 2; the fixed jaw 11 is fixedly installed on the output shaft of the driving member, and the movable jaw 12 is hinged to the fixed jaw 11; the fixed jaw 11 is fixedly provided with a fixed mounting arm 14, and a compression spring 15 is installed between the fixed mounting arm 14 and the movable jaw 12, and the two ends of the compression spring 15 are respectively abutted on the fixed mounting arm 14 and the movable jaw 12 to press the movable jaw 12 tightly against the fixed jaw 11. In operation, the fixed jaw 11 and the movable jaw 12 are in a combined state under the action of the compression spring 15, the terminal 4 enters from the feeding channel 13, the clamping hole of the fixed jaw 11 and the movable jaw 12 is flush with the outlet of the feeding channel 13, the terminal 4 enters the clamping hole due to vibration or external pressure, the driving member is started, and drives the fixed jaw 11 and the movable jaw 12 to move along a predetermined path, so as to move the terminal 4 from the feeding channel 13 to the specified position of the positioning mechanism 2; when the terminal 4 reaches the specified position of the positioning mechanism 2, the positioning mechanism 2 fixes the terminal 4, and the movable jaw 12 is reset upward, and the terminal 4 is fixed by the positioning mechanism 2, so as to force the movable jaw 12 to rotate, and the compression spring 15 is compressed under stress, thus the movable jaw 12 automatically releases the terminal 4, and the transfer of the terminal 4 is completed. This process does not require an additional power source, simplifies the operation process, and reduces the equipment cost.
