Description

Technical Field

[0001] This utility model relates to the field of screw machine technology, specifically a robotic arm for a double Y-type three-axis screw machine. Background Technology

[0002] A screw fastening machine is a small, automated machine for fastening screws. Its operating structure can generally be divided into two parts: a feeding section and an electric screwdriver section. The feeding section is responsible for screening and providing screws and nuts. After being gripped by a robotic arm, the screws are transferred to the fastening section, where the electric screwdriver section is responsible for fastening them. The emergence of screw fastening machines has both improved work efficiency and reduced the intensity of manual labor.

[0003] When feeding nuts onto a double Y-type three-axis screw machine, the robot clamps and fixes the outer wall of the nut, then rotates to transfer the nut to the processing position and puts it down. However, since the clamping blocks of the robot are mostly fixed with bolts, prolonged use and friction between the robot and the nut can easily lead to wear of the robot. When replacing the nut, it is necessary to remove the bolts with specific tools and replace the clamping blocks of the robot, which is a cumbersome operation and affects the efficiency of replacement. Utility Model Content

[0004] The purpose of this invention is to provide a robotic arm for a double Y-type three-axis screw machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A robotic arm for a double Y-type three-axis screw machine includes: a frame, a vibratory feeder and a support frame disposed on one side of the frame, a locking assembly mounted on the top surface of the frame, a robotic arm fixedly mounted on the top surface of the support frame, and a clamping and transmission assembly mounted on one end of the robotic arm; and further includes:

[0007] The fixing mechanism is located above the frame. The fixing mechanism includes a moving bar installed at the lower end of the clamping transmission assembly, a clamping block is provided below the moving bar, and pull rods and circular plates are provided on both sides of the moving bar. The fixing mechanism is used to fix the clamping block.

[0008] The blocking mechanism is located above the frame and includes L-shaped plates on both sides of the moving bar. A lifting rod is fixedly installed on the top surface of the L-shaped plate. The blocking mechanism is used to block the circular plate.

[0009] Preferably, a limiting strip is fixedly installed on the side of the moving strip, and a limiting groove is formed on the side of the clamping block, with the inner wall of the limiting groove slidingly connected to the outer wall of the limiting strip.

[0010] Preferably, a fixing block is fixedly installed on the top surface of one side of the clamping block, and slots are respectively opened on both sides of the fixing block. A groove is opened on the bottom surface of the moving strip, and the inner wall of the groove is slidably connected to the outer wall of the fixing block.

[0011] Preferably, the movable strip has two cavities inside, and movable plates are slidably installed on the inner walls of the two cavities. A locking block is fixedly installed on the side of each of the two movable plates, and one end of the locking block slides through the inner wall of the cavity and engages with the locking groove.

[0012] Preferably, one end of the pull rod is fixedly connected to the side of the circular plate, and the other end of the pull rod slides through the side of the moving strip and is fixedly connected to the side of the moving plate.

[0013] Preferably, an elastic element is slidably installed on the outer wall of the pull rod, and the two ends of the elastic element are fixedly connected to the side of the moving plate and the inner wall of the cavity, respectively.

[0014] Preferably, T-shaped grooves are provided on both sides of the movable strip, and T-shaped blocks are slidably installed on the inner wall of the T-shaped grooves. The top surface of the T-shaped blocks is elastically connected to the upper inner wall of the T-shaped grooves through an elastic element.

[0015] Preferably, the side of the L-shaped plate is fixedly connected to the side of the T-shaped block, and a locking groove is provided on the bottom surface of the L-shaped plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model involves pulling a circular plate, which in turn moves a pull rod. The pull rod then moves a movable plate and presses against an elastic element. The movable plate then moves a clamping block out of its slot, thus removing the clamping block from the slot. This facilitates the removal of the clamping block. When the clamping block is worn out after prolonged use, it can be quickly disassembled and replaced without the need for specific tools, thereby improving the replacement efficiency of the clamping block and production efficiency.

[0018] By pulling the lifting rod, the L-shaped plate moves, causing the T-shaped block to move within the T-groove and press against the second elastic element. Then, pulling the circular plate moves the pull rod a certain distance, loosening the lifting rod. Under the elastic force of the second elastic element, the T-shaped block and L-shaped plate move downwards. The locking groove on the L-shaped plate contacts the outer wall of the pull rod, and the L-shaped plate blocks and locks the circular plate, further locking the clamping block. This prevents the clamping block from moving into the slot when disassembling the clamping block, thus improving the efficiency of disassembling the clamping block. Attached Figure Description

[0030] like Figures 1-5 As shown, this application provides a robotic arm for a dual Y-type three-axis screw machine, comprising: a frame 1, a vibratory feeder 102 and a support frame 103 disposed on one side of the frame 1, a locking assembly 101 mounted on the top surface of the frame 1, a robotic arm 104 fixedly mounted on the top surface of the support frame 103, and a clamping transmission assembly 105 mounted on one end of the robotic arm 104, and further comprising:

[0031] The fixing mechanism 2 is located above the frame 1. The fixing mechanism 2 includes a moving bar 201 installed at the lower end of the clamping transmission assembly 105, a clamping block 203 is provided below the moving bar 201, and a pull rod 211 and a circular plate 212 are provided on both sides of the moving bar 201. The fixing mechanism 2 is used to fix the clamping block 203.

[0032] Specifically, such as Figures 1-5 As shown, a limiting strip 202 is fixedly installed on the side of the moving strip 201, and a limiting groove 204 is opened on the side of the clamping block 203. The inner wall of the limiting groove 204 is slidably connected to the outer wall of the limiting strip 202.

[0033] In this embodiment, the clamping block 203 is limited by the limiting strip 202 and the limiting groove 204, making the clamping block 203 more stable.

[0034] Specifically, such as Figures 1-5 As shown, a fixing block 205 is fixedly installed on the top surface of one side of the clamping block 203. The fixing block 205 has slots 206 on both sides. The bottom surface of the moving strip 201 has a groove 207. The inner wall of the groove 207 is slidably connected to the outer wall of the fixing block 205.

[0035] In this embodiment, the fixed block 205 is limited by the groove 207.

[0036] Specifically, such as Figures 1-5 As shown, the movable strip 201 has two cavities 208 inside. Movable plates 209 are slidably installed on the inner walls of the two cavities 208 respectively. A locking block 210 is fixedly installed on the side of the two movable plates 209 respectively. One end of the locking block 210 slides through the inner wall of the cavity 208 and engages with the locking groove 206.

[0037] In this embodiment: the cavity 208 limits the movement of the moving plate 209, making the movement of the moving plate 209 more stable; the locking block 210 engages with the locking slot 206, thereby fixing the fixing block 205 and the clamping block 203.

[0038] Specifically, such as Figures 1-5 As shown, one end of the pull rod 211 is fixedly connected to the side of the circular plate 212, and the other end of the pull rod 211 slides through the side of the moving bar 201 and is fixedly connected to the side of the moving plate 209.

[0039] In this embodiment: by using the pull rod 211 and the circular plate 212, the moving plate 209 can be moved by pulling the circular plate 212.

[0040] Specifically, such as Figures 1-5 As shown, an elastic element 213 is slidably installed on the outer wall of the pull rod 211. The two ends of the elastic element 213 are fixedly connected to the side of the moving plate 209 and the inner wall of the cavity 208, respectively.

[0041] In this embodiment, the elastic element 213 applies elastic force to the movable plate 209.

[0042] The blocking mechanism 3 is located above the frame 1. The blocking mechanism 3 includes L-shaped plates 304 located on both sides of the moving bar 201. A lifting rod 305 is fixedly installed on the top surface of the L-shaped plate 304. The blocking mechanism 3 is used to block the circular plate 212.

[0043] Specifically, such as Figures 1-5 As shown, T-shaped grooves 301 are respectively provided on both sides of the movable strip 201. T-shaped blocks 302 are slidably installed on the inner wall of the T-shaped grooves 301. The top surface of the T-shaped blocks 302 is elastically connected to the upper inner wall of the T-shaped grooves 301 through an elastic element 303.

[0044] In this embodiment: the T-shaped groove 301 limits the T-shaped block 302, making the movement of the T-shaped block 302 more stable, and the elastic element 303 applies elastic force to the T-shaped block 302.

[0045] Specifically, such as Figures 1-5 As shown, the side of the L-shaped plate 304 is fixedly connected to the side of the T-shaped block 302, and a locking groove 306 is provided on the bottom surface of the L-shaped plate 304.

[0046] In this embodiment, the circular plate 212 and the pull rod 211 are blocked and locked by the L-shaped plate 304 and the locking groove 306.

[0047] The specific solution is as follows: Vibratory feeder 102 vibrates the nut to the loading position. Robotic arm 104 drives clamping transmission assembly 105 to move above the nut. Clamping transmission assembly 105 drives clamping block 203 to clamp the nut. Robotic arm 104 then lowers the nut and locks it using locking assembly 101. When clamping block 203 wears out after prolonged use and needs replacement, lifting rod 305 is pulled, moving L-shaped plate 304. L-shaped plate 304 moves T-shaped block 302 along the inner wall of T-groove 301, pressing on elastic element 2 303. Subsequently, circular plate 212 is pulled, moving pull rod 211 a certain distance. Pull rod 211 moves moving plate 209, pressing on elastic element 1 213. Moving plate 209 moves locking block 210. Move the lever 305 and remove it from the slot 206. The locking block 210 is no longer engaged with the slot 206. Loosen the lever 305. Under the elastic force of the second elastic element 303, push the T-shaped block 302 and the L-shaped plate 304 downward. The locking groove 306 on the L-shaped plate 304 contacts the outer wall of the lever 211. The L-shaped plate 304 blocks and locks the round plate 212, thus facilitating the removal of the clamping block 203. When installing the clamping block 203, move the fixing block 205 on the clamping block 203 into the groove 207. Pull the lever 305 to move the L-shaped plate 304 upward. The L-shaped plate 304 no longer blocks the round plate 212. Under the elastic force of the first elastic element 213, the locking block 210 engages with the slot 206, fixing the clamping block 203. Loosen the lever 305.
