Description

Technical Field

[0001] The utility model relates to the field of mechanical parts appearance processing, in particular to an auxiliary device for trimming lead parts. Background Art

[0002] Lead is a common heavy metal, and lead parts refer to various parts made of lead or lead alloys.

[0003] After casting, lead parts have potholes on their surface and have a low density. They need to be further compacted by cold pressing equipment to achieve a smooth surface. However, burrs will also appear on the surface of the parts, so trimming is required.

[0004] However, to save manufacturing costs, some manufacturers still rely on manual trimming or simple mechanical equipment. However, manual trimming is difficult to ensure consistency and can easily lead to dimensional deviations in parts. It is also time-consuming and cannot meet the needs of mass production. Conventional mechanical equipment still requires frequent manual intervention, and its simple positioning functions cannot achieve high-precision positioning and trimming, resulting in poor dimensional consistency in parts.

[0032] When in use, first, place the lead part 10 to be trimmed in the two loading seats 9. The loading seats 9 are designed to be rotatable to facilitate subsequent trimming processing. A synchronous wheel 11 and a synchronous wheel 2 111 are provided under the loading seats 9, which are connected by a synchronous belt 12 and form a transmission system together with the synchronous wheel 3 112; start the electric cylinder group 4, and its push rod drives the guide rod 5 and the pressure block 6 to move downward, so that the protrusion of the pressure block 6 contacts the top of the lead part 10, and the lead part 10 is pressed against the loading seat 9. This process ensures that the lead part 10 will not move during the trimming process, thereby improving the trimming efficiency. After the motor 14 is started, its output shaft drives the synchronous wheel 3 112 to rotate, and then drives the synchronous wheel 11 and the synchronous wheel 2 111 to rotate through the synchronous belt 12, and the loading seat 9 rotates with the synchronous wheel 11, so that the lead part 10 is rotated to a suitable angle for subsequent trimming operations, and the electric cylinder 22 drives the tool holder 16 to move along the guide rail 15 to one side of the lead part 10. At this time, the tool 21 has been pre-adjusted. The position of the tool 21 can be fine-tuned by adjusting the fixed block 20 on the tool holder 19 and the screw 171 and the screw 2 18 to ensure that the tool The contact surface between 21 and lead part 10 is accurate. As the loading seat 9 rotates, the tool 21 trims and cuts the lead part 10. A notch corresponding to the outer contour of the workpiece is provided at the end of the tool 21 to ensure that the cutting trajectory during the trimming process meets the shape requirements of the lead part 10. This process removes burrs on the surface of the lead part 10 through the cutting action of the tool 21.

The air outlet of the fan 8 is directed towards the workpiece to be processed. The fine waste chips generated during the trimming process can be blown away while the pressing block 6 moves downward to prevent the waste chips from flying and affecting the working environment. The operation of the entire device is controlled by the controller 23. The controller 23 is connected to the electric cylinder group 4, the motor 14, the electric cylinder 22 and other components. The operator can set the sequence and parameters of each action through the controller 23 to realize automated trimming operations.
