Description

Technical Field

[0001] This utility model relates to the field of copper bar manufacturing equipment, and in particular to a copper bar nut riveting device. Background Technology

[0002] During the production of copper bars, nuts need to be riveted to the pre-set positions on the copper bars to enable subsequent assembly and connection functions. Currently, the riveting of copper bar nuts mostly relies on manual operation: the nut is picked up from the stockpile by hand, manually positioned to the riveting position on the copper bar, and then riveted using manual tools or simple equipment.

[0003] This method has obvious drawbacks: First, manual material handling and positioning are inefficient and difficult to adapt to the needs of mass production, resulting in a slow production cycle. Second, manual positioning has poor accuracy, and the preset riveting positions of the nuts and braces are prone to misalignment, affecting the riveting quality and subsequent assembly accuracy. Third, manual operation has poor consistency. Affected by factors such as the operator's skill level and fatigue, the riveting force and angle are unstable, which can easily lead to problems such as insecure riveting and nut deformation, increasing the product scrap rate.

[0004] Therefore, there is an urgent need to design a copper bar nut riveting device with a high degree of automation, precise positioning, and stable riveting to solve the above-mentioned defects of the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a copper bar nut riveting device to achieve automated feeding, precise positioning and stable riveting of copper bar nuts, thereby improving production efficiency and product quality.

[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: a copper bar nut riveting device, comprising:

[0007] A nut feeding mechanism, comprising a vibratory feeder, a linear vibrating track, and a nut receiving module, wherein the vibratory feeder, the linear vibrating track, and the nut receiving module are connected in sequence and are used to achieve orderly nut feeding.

[0008] A nut picking and riveting mechanism comprises a bracket, a first floating plate, a second floating plate, a riveting cylinder, a transverse cylinder, a lifting cylinder, a slide rail, a slide block, a gripper cylinder, and a gripper assembly. The first floating plate is slidably mounted on the bracket. The lifting cylinder is fixed on the first floating plate and drives the second floating plate to move up and down. The transverse cylinder and the slide rail are horizontally parallel to each other on the second floating plate. The slide block slides on the slide rail and is driven by the transverse cylinder. The gripper cylinder is fixed on the slide block and drives the gripper assembly to clamp or release the nut. The riveting cylinder is fixed on the bracket, and the middle section of the riveting rod of the riveting cylinder is fixedly connected to the first floating plate. The second floating plate has a through hole corresponding to the riveting rod.

[0009] The preferred technical solution is as follows: the nut receiving module consists of a lifting cylinder, a connecting plate, a positioning seat, a positioning cylinder, and positioning claws. The lifting cylinder is used to drive the positioning plate to move up and down. The positioning seat is fixed on the positioning plate and is correspondingly set to the discharge end of the linear vibration track. The top side of the positioning seat is provided with a positioning groove for positioning the nut. The top side of the positioning seat is also provided with a channel connecting the positioning groove and the edge of the positioning groove. The channel is matched with the discharge end of the linear vibration track and is used to transport the nut. The positioning seat has an installation channel inside that connects the two opposite side walls of the positioning groove. The positioning claws are set in the installation channel and are driven by the positioning cylinder fixed to the bottom side of the connecting plate to clamp or release the nut.

[0010] The preferred technical solution is as follows: the bracket is composed of multiple guide posts and a fixed plate. The multiple guide posts are vertically fixed to the bottom side of the fixed plate. The floating plate is provided with multiple guide sleeves. The guide posts pass through the guide sleeves and are slidably connected to the guide sleeves. The riveting cylinder is fixed to the fixed plate.

[0011] The preferred technical solution is as follows: the second floating plate is disposed on the bottom side of the first floating plate, and multiple vertically arranged guide posts are fixedly disposed on the top side of the second floating plate. Multiple guide sleeves are disposed on the first floating plate, and the guide posts are inserted into the guide sleeves and slidably connected to the guide sleeves. The portions of the multiple guide posts extending out of the first floating plate are connected by connecting rods. The lifting cylinder is fixed to the first floating plate and is used to drive the connecting rods to lift.

[0012] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0013] Automated feeding: Nuts are sorted and arranged by a vibratory feeder and then stably transported to the nut receiving module via a linear vibrating track, replacing manual material handling, greatly improving feeding efficiency and reducing labor costs.

[0014] Precise positioning: The nut receiving module initially positions the nut through the positioning groove, and then uses the positioning cylinder to drive the positioning gripper to hold and fix it, ensuring that the nut is stable in position before picking up the material; the picking and riveting mechanism precisely controls the displacement of the gripper assembly through the horizontal movement cylinder and the lifting cylinder, so as to achieve the precise transfer of the nut from the receiving position to the copper bar riveting position, solving the problem of manual positioning offset.

[0015] Stable riveting: The riveting cylinder drives floating plate one and floating plate two to move downward as a whole through the riveting rod. Combined with the gripper assembly to stably hold the nut, it can provide a stable riveting force. At the same time, floating plate one and the bracket are slidably engaged through guide post one and guide sleeve one, and floating plate two and floating plate one are slidably engaged through guide post two and guide sleeve two. This ensures the stability of the movement trajectory during riveting, avoids riveting angle deviation, improves the consistency of riveting quality, and reduces the product scrap rate.
