Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, and in particular to the stamping and welding processing of hook seats. Background Technology

[0002] like Figure 1 , 2 As shown, during the production of the hook holder, rivets 801 and hook pieces 802 need to be assembled together. First, assembly holes are pre-drilled on the hook pieces 802. The rivets 801 then pass through these holes and are riveted together using a punch press, connecting the rivets and hook pieces. To prevent the rivets from rotating relative to the hook pieces, the riveting points are further welded for fixation. Currently, the riveting and welding processes are performed on different machines, requiring repeated loading, unloading, and positioning. This results in numerous steps, impacting production efficiency. Furthermore, each machine requires an operator, leading to high labor costs. Summary of the Invention

[0003] The purpose of this utility model is to provide a hook seat stamping and welding integrated machine, which realizes the continuous completion of stamping and welding work on one machine, improves production efficiency and reduces labor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The hook seat stamping and welding integrated machine has the following features: Base; The turntable is mounted on the base and can rotate intermittently. Several molds are arranged in a ring around the center of the turntable on the upper side of the turntable. Each mold corresponds to a work station. The molds are fitted with rivets and hook pieces for positioning. The turntable also includes a stamping mechanism, a welding mechanism and a discharge robot that are arranged in sequence and spaced according to the rotation direction of the turntable. The stamping mechanism has a punch located on the upper side of the turntable and capable of moving up and down. The punch is used to stamp rivets placed in the die, so that the rivets and hook pieces are riveted together. The welding mechanism has a welding gun and a sensing element. The welding gun is activated to start welding by detecting whether there is a workpiece on the mold through the sensing element. The welding mechanism then welds and fixes the riveted rivets and hook pieces to form a hook seat. The unloading robot is used to remove the welded hook seat from the mold.

[0005] A further aspect of the above scheme is that the sensing element is a push rod, which is positioned on the lifting seat and obtains an upright posture. The push rod has the property of being able to extend and retract relative to the lifting seat, so that when the push rod presses down to support the workpiece, it can adaptively float and retract.

[0006] A further improvement in the above scheme is that the lifting platform is equipped with a sensing sensor, which is used to sense the extension and retraction of the top rod and output a signal to control the start of welding work.

[0007] A further improvement in the above scheme is that the push rod has a grounding and conductive property, so that when the push rod is pressed down to support the workpiece, it provides grounding and conduction to facilitate welding.

[0008] A further improvement in the above scheme is that the lifting seat is connected to the telescopic end of the lifting cylinder, and the lifting cylinder is mounted on the machine base.

[0009] The above solution is further described as follows: the mold has an upward-facing cavity and an ejector hole located on the lower side of the cavity and connected to the cavity; the cavity has a groove adapted for horizontal placement of the hook piece and a positioning hole recessed from the bottom of the groove and adapted for placement of rivets; the ejector hole is adapted for insertion of a stripping ejector pin to lift the machined hook seat, so that the ejection robot can grab the hook seat and remove it.

[0010] A further aspect of the above scheme is that the ejector pin is vertically arranged on the lower side of the turntable and connected to the telescopic end of the lifting cylinder, and the lifting cylinder is vertically installed on the machine base; the turntable has a corresponding clearance hole pre-set, and the clearance hole is vertically connected to the ejector hole.

[0011] A further aspect of the above scheme is that the welding torch is mounted on an adjustable multi-degree-of-freedom support, which is mounted on a machine base.

[0012] This utility model has a simple, scientific, and reasonable structure with low investment costs. By using a turntable for rotational transmission, it can continuously complete the stamping and welding of hook seats on the same machine, reducing loading and unloading processes and improving production efficiency. Furthermore, the introduction of sensing elements into the welding mechanism is used to detect whether there is a workpiece on the mold to start welding, automatically identifying and processing, ensuring accurate production and production safety, reducing manual labor, lowering labor costs, and making it suitable for modern automated production.

Detailed Implementation

[0014] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

[0015] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0016] See Figure 3 , 4 Figures 5, 6, and 7 show schematic diagrams of a preferred embodiment of this utility model. This utility model relates to a hook seat stamping and welding integrated machine, used to connect rivets and hook pieces together to form a hook seat. It has: a machine base 1, a turntable 2, a stamping mechanism 3, a welding mechanism 4, and a discharge robot 5. The turntable 2 is mounted on the machine base and can rotate intermittently. Several molds 21 are arranged in a ring around the center of the turntable on the upper side of the turntable. Each mold 21 corresponds to a work station. The molds 21 are adapted to position and place rivets and hook pieces. The stamping mechanism 3, the welding mechanism 4, and the discharge robot 5 are distributed sequentially at intervals according to the rotation direction of the turntable and corresponding to the corresponding work stations, and are connected into a whole through the machine base 1 to construct the stamping and welding integrated machine. The stamping mechanism 3 has a punch 31, which is located on the upper side of the turntable 2 and can move up and down. The punch 31 is used to stamp the rivets placed in the mold 21, so that the rivets and hook pieces are riveted together. In actual implementation, a stamping support seat is also appropriately provided on the lower side of the turntable 2. The stamping support seat can be raised and lowered accordingly to support the mold 21 and cooperate with the punch 31 for stamping processing. The welding mechanism 4 has a corresponding welding gun 45 and a sensing element 41. The welding gun is activated to start welding by detecting whether there is a workpiece (rivet or hook piece) on the mold through the sensing element 41. The welding mechanism 4 then welds and fixes the riveted rivets and hook pieces to form a hook seat. The unloading robot 5 is used to remove the welded hook seat from the mold 21 to realize automatic unloading.

[0017] During operation, workers sequentially position the rivets and hook pieces in mold 21. Then, turntable 2 rotates, and mold 21 moves the rivets and hook pieces to stamping mechanism 3. Stamping mechanism 3 rivets and hook pieces are then riveted together. The specific stamping process principle is existing technology and will not be elaborated here. As the turntable continues to rotate, it conveys the riveted rivets and hook pieces to the welding station. Welding mechanism 4 uses sensing element 41 to detect whether there is a workpiece (rivet or hook piece) on the mold and activates welding gun 45 for welding. After welding, the turntable transfers the resulting hook seat to the unloading station. At this point, unloading robot 5 removes the welded hook seat from mold 21, achieving automatic unloading. This cycle repeats.

[0018] In this embodiment, the mold 21 has an upward-facing cavity and an ejector hole 211 located below the cavity and connected to it. The cavity has a groove 212 adapted for horizontal placement of the hook piece and a positioning hole 213 recessed from the bottom of the groove for placement of rivets. There are two positioning holes 213, allowing two rivets to be placed at opposite ends of the hook piece, with the hook piece horizontally stacked on top of the two rivets. The corresponding ends of the rivets pass through pre-set assembly holes in the hook piece for stamping, riveting, and welding. The ejector hole 211 is located between the two positioning holes. Between the positioning holes 213, the ejector hole 211 is adapted to be inserted into the ejector pin 6 to lift the machined hook seat, so that the ejector robot 5 can grab the hook seat and move it out. In order to facilitate the ejector robot 5 to grab the hook seat, the mold 21 is also provided with a clearance groove that spans the mold cavity opening. This is conducive to the two grippers of the ejector robot 5 closing and holding the hook seat. The structural principle of the ejector robot 5 is the prior art, and its principle will not be described in detail here. This utility model simply organically combines the existing robot structure to obtain automatic ejection operation.

[0019] The ejector pin 6 is vertically positioned on the lower side of the turntable 2 and connected to the telescopic end of the lifting cylinder 7, which is vertically mounted on the machine base. The turntable 2 has pre-set clearance holes that are vertically connected to the ejector hole 211. The telescopic movement of the lifting cylinder 7 drives the ejector pin 6, enabling it to lift the processed hook seat from bottom to top. This design is simple and has low investment costs.

[0020] The sensing element 41 is a push rod, which is positioned on the lifting seat 42 and has an upright posture. The push rod is capable of extending and retracting vertically relative to the lifting seat 42, allowing it to self-adaptively float and retract when it presses down on the workpiece, providing contact sensing and buffering. In this invention, the push rod presses down on a horizontally placed hook piece. The lifting seat 42 is connected to the telescopic end of the lifting cylinder 44, which is mounted on the machine base 1. The lifting cylinder 44 drives the lifting seat 42 to descend, simultaneously moving the push rod downwards. When the push rod presses down on the hook piece in the mold, its adaptive floating and retraction causes the other end of the push rod to bulge upwards. At this time, the lifting seat 42 is also equipped with a sensing sensor 43, which senses the extension and retraction of the push rod and outputs a signal to control the start of welding. Specifically, the sensing sensor 43 senses the upper position of the push rod, thereby outputting a signal to control the start of welding. The sensing sensor 43 can be a photosensitive sensor or a magnetoelectric sensor, etc.

[0021] In this embodiment, the top rod has a grounding and conductive property, so that when the top rod is pressed down to support the hook piece, it provides grounding and conduction, thereby cooperating with the welding and improving the safety of processing and production.

[0022] The welding torch 45 is mounted on an adjustable multi-degree-of-freedom bracket 46, which is mounted on the machine base. The multi-degree-of-freedom bracket 46 allows for three-dimensional spatial adjustment of the welding torch 45 to precisely align with the welding area. In this embodiment, two welding torches 45 are provided, each corresponding to one of the two rivet engagement positions. During welding, the multi-degree-of-freedom bracket 46, driven by a power cylinder, lowers the welding torch 45 for welding. After welding, the multi-degree-of-freedom bracket 46 returns the welding torch 45 to its original position, and this process is repeated. This embodiment also includes a shielding plate 47 at the welding station. This shielding plate 47 is connected to the lifting seat 42 and moves up and down with the top rod. The shielding plate 47 serves to block sparks, preventing accidents caused by flying sparks during welding and improving production safety.

[0023] This utility model has a scientific and reasonable structure and low investment cost. By using a turntable for rotational transmission, it can continuously complete the stamping and welding of hook seats on the same machine, reducing loading and unloading processes and improving production efficiency. Furthermore, the introduction of sensing elements into the welding mechanism is used to detect whether there is a workpiece on the mold to start welding, automatically identifying and processing, ensuring accurate production and production safety, reducing manual labor, lowering labor costs, and making it suitable for modern automated production.

[0024] While the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to the same structure and operation as described above and the accompanying drawings. For those skilled in the art, many equivalent improvements and variations can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and variations should all fall within the scope of protection claimed by the present invention.
