Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a high-speed servo flat wire coiling and butt welding integrated machine. Background Technology

[0002] In machining, some ring-shaped metal workpieces require flat metal wire to be bent into a ring shape, then cut, and the cut surfaces welded together to form a ring-shaped metal ring.

[0003] Existing flat wire coiling machines can only coil flat wire into rings before cutting; subsequent welding of these rings requires additional welding equipment or manual welding. This welding process necessitates transferring, clamping, and welding the rings, resulting in low production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed servo flat wire coil welding machine with a simple and reasonable structural design. It can efficiently clamp and fix the ring coil, and facilitate the welding of the first and last ends of the ring coil. It reduces the flow of workpieces, avoids multi-equipment collaborative processing, and improves production efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A high-speed servo flat wire coiling and butt welding integrated machine includes a feeding rack, a flat wire coiling machine, a coil butt welding clamping assembly, a coil feeding robot, and a coil unloading robot;

[0007] The feeding rack is located on one side of the flat wire coiling machine, and a coil welding clamping assembly is located on the front side of the flat wire coiling machine. A coil feeding robot and a coil unloading robot are located on one side of the coil welding clamping assembly. The flat wire coiling machine is existing technology and can be equipped with existing coiling equipment. It bends the flat metal wire into a ring coil and then cuts it. The coil feeding robot picks up the cut ring coil and transfers it to the coil welding clamping assembly. After the coil welding clamping assembly clamps and fixes the ring coil, the two ends of the ring coil can be welded using automated welding equipment or manually. After welding, the coil unloading robot removes the ring coil from the coil welding clamping assembly.

[0008] The coil welding clamping assembly includes a mounting base, a slide block, front and rear positioning components, a clamping component, and a frame. The frame is vertically arranged, with a horizontally positioned worktable at its top. The mounting base is fixedly mounted on the worktable. The top of the mounting base has a horizontally positioned slide rail, with a forward / reverse motor on its front side and a mounting cavity in its middle. The output shaft of the forward / reverse motor is connected to a lead screw, which is located in the mounting cavity, and a nut sleeve is fitted on the lead screw. A slider is fixedly mounted at the bottom of the slide block, which is fitted onto the slide rail. The bottom of the slide block is also fixedly connected to the nut sleeve. The forward / reverse motor drives the lead screw to rotate, pushing the nut sleeve to slide, thereby moving the slide block along the slide rail.

[0009] The front and rear positioning components include a positioning cylinder, a clamping push block, a clamping seat, and an outer cylinder; the positioning cylinder and the outer cylinder are horizontally fixed on the slide block, and the output shaft of the positioning cylinder is connected to the clamping push block; the outer cylinder is located in front of the positioning cylinder, and a cavity is provided in the middle of the outer cylinder, and the output shaft of the positioning cylinder is located in the middle of the outer cylinder; a clamping seat is fixed on the front side of the outer cylinder.

[0010] The outer wall of the clamping base is provided with an annular groove for placing an annular coil;

[0011] The clamping base is provided with a sliding groove (axial direction). The clamping push block slides in the sliding groove to push the annular coil against the front inner wall of the annular groove, and cooperates with the clamping push block to fix and position the annular coil.

[0012] The clamping assembly includes a clamping cylinder and an arc-shaped pressure plate. The output shaft of the clamping cylinder is horizontally fixed above the outer cylinder, and its housing is connected to the arc-shaped pressure plate via a guide rod. When the clamping cylinder operates, it drives the arc-shaped pressure plate to move. The end face of the arc-shaped pressure plate is an arc surface, which is adapted to the annular groove. The arc-shaped pressure plate has a clearance groove in the middle for clamping and displaced push blocks.

[0013] The ring-feeding robot includes a gripper and a cross slide assembly. The cross slide assembly is a mounting platform that can move laterally and longitudinally in the horizontal direction, and the gripper is fixed on the cross slide assembly.

[0014] The unloading robot includes an unloading gripper, an unloading slide, and an unloading cylinder. The unloading gripper is fixed on the unloading slide, and the output shaft of the unloading cylinder is connected to the unloading slide. The bottom of the unloading slide is equipped with an unloading slider, which is sleeved on an unloading slide rail. The unloading slide rail is located on the worktable.

[0015] Preferably, the frame is equipped with a lifting cylinder, and the output shaft of the lifting cylinder is connected to the worktable, driving the worktable to move in the vertical direction.

[0016] Briefly describing its working principle: The coil-feeding robot can move horizontally and vertically. After clamping the ring coil from the flat wire coiling machine, it places the ring coil into the annular groove on the clamping base. The front and rear positioning components and the clamping components respectively push the clamping push block and the arc-shaped pressure plate to limit and fix the ring coil. The ring coil, which is limited and fixed, is convenient for subsequent welding.

[0017] After welding, the clamping push block and arc-shaped pressure plate are released. The unloading robot grabs the ring coil and moves it to the left by a certain stroke, so that the ring coil is separated from the ring groove. Then the forward and backward motor drives the slide to move forward (to the front of the equipment), that is, the clamping seat is pulled out from the middle of the ring coil. The unloading robot moves laterally to move the ring coil to the receiving position.

[0018] The beneficial effects of this utility model are:

[0019] Its structural design is simple and reasonable, which can efficiently clamp and fix the ring coil and facilitate the welding of the ring coil head to tail; it reduces the flow of workpieces, avoids multi-equipment collaborative processing, and improves production efficiency.
