Technical Field

[0001] This invention relates to the field of hardware welding technology, and in particular to an automated hardware manufacturing processing equipment. Background Technology

[0002] Welding nuts to pipes requires workers to align them before welding can begin. This manual operation is prone to problems such as inaccurate alignment and is time-consuming and labor-intensive. In the existing technology, Chinese Patent No. CN109079305A discloses an automatic welding device for welding nuts. Although it can automatically weld welding nuts, it cannot weld the welding nuts to the inside of the pipe. Especially when the pipe has multiple bolt holes, the feeding of welding nuts and continuous welding operations cannot be achieved, and manual welding is still required. Summary of the Invention

[0003] To overcome the shortcomings mentioned in the background art, this invention provides an automated processing equipment for hardware parts production, including a welding machine, a nut feeder, a mounting table, a two-axis moving platform, a clamp, a mounting frame, and a limiting component. The welding machine is equipped with a nut feeder. A mounting table is located on one side of the welding machine. A two-axis moving platform is mounted on the mounting table. A clamp is mounted on the moving part of the two-axis moving platform, which clamps a square tube and drives the clamp and the square tube to move back and forth and left and right. A mounting frame is fixedly connected to the clamp. A limiting component is mounted on the upper side of the mounting frame, which transfers and restricts the welding nut from the nut feeder inside the square tube and aligns it with the bolt hole.

[0004] More preferably, the welding machine has an upper electrode and a lower electrode, through which the welding nut is welded to the square tube; the lower electrode has a groove for accommodating the welding nut.

[0005] More preferably, the nut feeder has a sluice, and the side wall of the sluice has a protrusion for limiting the welding nut; a rotating plate is rotatably connected in the sluice, and a torsion spring is provided at the rotating shaft of the rotating plate.

[0006] More preferably, the two-axis moving platform includes a first pneumatic guide rail and a second pneumatic guide rail; the first pneumatic guide rail is mounted on the mounting platform; the second pneumatic guide rail is mounted on the moving part of the first pneumatic guide rail; the second pneumatic guide rail has two moving parts, and each of the two moving parts is equipped with a clamp.

[0007] More preferably, the gripper is connected to the two-axis moving platform via an elastic pad.

[0008] More preferably, the limiting component includes a first pneumatic push rod, a second pneumatic push rod, and an expander; the first pneumatic push rod is mounted on the mounting bracket; the telescopic part of the first pneumatic push rod is fixedly connected to the second pneumatic push rod; and the telescopic part of the second pneumatic push rod is connected to the expander.

[0009] More preferably, the expander is detachably wrapped with a cleaning bag.

[0010] More preferably, it also includes a connecting plate and a limiting seat; the right rear side of the mounting platform is connected to the limiting seat via the connecting plate.

[0011] More preferably, it also includes a smoke removal assembly, which includes a third pneumatic guide rail, a third pneumatic push rod, an air intake hood, and an air blowing hood; the third pneumatic guide rail is fixedly connected to the lower side of the mounting bracket; the third pneumatic guide rail has two moving parts, each of which is fixedly connected to a third pneumatic push rod; the right side of the third pneumatic push rod telescopic part is fixedly connected to the air intake hood, and the first shielding part of the air intake hood is connected to an air intake device; the left side of the third pneumatic push rod telescopic part is fixedly connected to the air blowing hood, and the second shielding part is connected to an air blowing device, and the second shielding part has a through hole so that the second shielding part can be fitted onto the outside of the lower electrode.

[0012] More preferably, it also includes an air blower and a connecting rod; the air blower is fixedly connected to the telescopic part of the second pneumatic push rod, and the air blower has a downward-facing air outlet; a connecting rod with a radius smaller than the square tube bolt hole is fixedly connected to the bottom of the air blower, and the connecting rod is fixedly connected to the expander.

[0013] The beneficial effects of this invention are as follows: This invention achieves automation by using a nut feeder and an expander to transfer multiple welding nuts to the bolt holes inside a square tube. The expander restricts the movement of the welding nuts and the square tube, allowing them to move synchronously. This enables the batch welding pre-feeding of welding nuts, which greatly improves efficiency compared to workers placing a welding nut after each welding operation. This invention enables automatic feeding of welding nuts onto the lower electrode and automates the welding of all welding nuts onto the inside of the square tube (at the bolt holes). It eliminates the need to expose the lower electrode to place the welding nuts during the welding process (which is inefficient as the lower electrode is exposed for each welding nut). Furthermore, the expansion device moves the welding nuts along with the square tube, ensuring that the welding nuts remain aligned with the bolt holes of the square tube even when they enter the groove of the lower electrode, thus preventing welding deviations.

Detailed Implementation

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0017] Example 1: As Figures 1-11As shown, an automated hardware manufacturing processing equipment includes a welding machine 1, a nut feeder 2, a mounting platform 3, a two-axis moving platform 4, a clamp 5, a mounting frame 6, and a limiting component 7. The welding machine 1 is equipped with a nut feeder 2, and welding nuts 100 are placed in the nut feeder 2 by an external nut conveying device or by a worker for later use. The mounting platform 3 is provided on one side of the welding machine 1. The two-axis moving platform 4 is installed on the mounting platform 3. The clamp 5 is installed on the moving part of the two-axis moving platform 4, and the clamp 5 clamps a square tube 200. The two-axis moving platform 4 drives the clamp 5 and the square tube 200 to move back and forth and left and right. The mounting frame 6 is fixedly connected to the fixed part of the clamp 5. The limiting component 7 is installed on the upper side of the mounting frame 6, and the limiting component 7 transfers the welding nuts 100 in the nut feeder 2 and restricts them inside the square tube 200 and aligns them with the bolt holes.

[0018] The welding machine 1 has an upper electrode 1a and a lower electrode 1b. The welding nut 100 is welded to the square tube 200 by the upper electrode 1a and the lower electrode 1b. The lower electrode 1b has a groove 1c for accommodating the welding nut 100.

[0019] like Figure 2 , Figure 4 As shown, the nut feeder 2 has a slide groove, and the side wall of the slide groove is provided with a protrusion 2a for limiting the welding nut 100; a rotating plate 2b is rotatably connected in the slide groove, and a torsion spring is provided at the rotating shaft of the rotating plate 2b to keep the rotating plate 2b initially in a vertical state.

[0020] When the external nut conveying equipment or the worker places the welding nut 100 in the nut feeder 2, the welding nut 100 is placed between the two protrusions 2a, and the right side of the welding nut 100 is in contact with the rotating plate 2b, so that the welding nut 100 is in the standard position and can be aligned with the bolt hole on the square tube 200. It should be noted that the distance between adjacent protrusions 2a is set with reference to the bolt hole on the square tube 200.

[0021] The two-axis moving platform 4 includes a first pneumatic guide rail 41 and a second pneumatic guide rail 42. The first pneumatic guide rail 41 is mounted on the mounting platform 3. The second pneumatic guide rail 42 is mounted on the moving part of the first pneumatic guide rail 41. The second pneumatic guide rail 42 has two moving parts, and a gripper 5 is mounted on each of the two moving parts. By controlling the movement of the moving part of the first pneumatic guide rail 41, the gripper 5 is driven to move back and forth. By controlling the movement of the moving part of the second pneumatic guide rail 42, the gripper 5 is driven to move left and right. In this way, the gripper 5 is driven to move back and forth and left and right by the two-axis moving platform 4.

[0022] like Figure 8As shown, the clamp 5 is connected to the two-axis moving platform 4 (the moving part of the second pneumatic guide rail 42) through the elastic pad 5a; when the upper electrode 1a moves down to weld the welding nut 100 and the square tube 200 together, the welding nut 100 cannot move down because it is supported by the lower electrode 1b. The elastic pad 5a is provided so that when the upper electrode 1a presses down on the square tube 200, the square tube 200 moves down slightly, so that the welding foot of the welding nut 100 fits tightly with the square tube 200 and the weld is firm.

[0023] The limiting component 7 includes a first pneumatic push rod 71, a second pneumatic push rod 72, and an expander 73; the first pneumatic push rod 71 is mounted on the mounting bracket 6; the telescopic part of the first pneumatic push rod 71 is fixedly connected to the second pneumatic push rod 72; the telescopic part of the second pneumatic push rod 72 is connected to the expander 73.

[0024] The expansion unit 73 is detachably wrapped with a cleaning bag. When the expansion unit 73 is inserted into the inside of the welding nut 100 and expands, the cleaning bag absorbs and cleans the liquid, dust and other impurities inside the welding nut 100.

[0025] It also includes a connecting plate 81 and a limiting seat 82; the right rear side of the mounting platform 3 is connected to the limiting seat 82 through the connecting plate 81. When the square tube 200 is placed into the clamp 5 for clamping, the right end of the square tube 200 is pressed against the limiting seat 82 to achieve limiting, so that the clamp 5 can clamp the square tube 200 in the standard position.

[0026] Welding nuts to pipes requires workers to align them before welding can begin. This manual operation is prone to problems such as inaccurate alignment and is time-consuming and labor-intensive. In the existing technology, Chinese Patent No. CN109079305A discloses an automatic welding device for welding nuts. Although it can automatically weld welding nuts, it cannot weld the welding nuts to the inside of the pipe. Especially when the pipe has multiple bolt holes, the feeding of welding nuts and continuous welding operations cannot be achieved, and manual welding is still required.

[0027] To address the aforementioned problems, this invention is proposed. When using this invention, as follows: Figures 1-5 As shown, firstly, the square tube 200 is placed in two clamps 5 (either manually or by a tube feeding device), and the right end of the square tube 200 is pressed against the limiting seat 82 to achieve limiting; at the same time, the welding nut 100 is placed in the nut feeder 2, specifically between the two protrusions 2a, and attached to the left side of the rotating plate 2b. Specifically, in the attached drawings of this invention, the square tube 200 has 4 bolt holes, and there are also 4 welding nuts 100 placed there; Next, as Figure 2 As shown, the two-axis moving platform 4 drives the clamp 5 to move from right to left, placing the square tube 200 onto the nut feeder 2, as... Figure 6 , Figure 7 As shown, at this time, the bolt hole of the square tube 200 is aligned with the welding nut 100. Then, the telescopic part of the first pneumatic push rod 71 is controlled to push the second pneumatic push rod 72 to move towards the square tube 200. Then, the telescopic part of the second pneumatic push rod 72 is controlled to push the expander 73 downward. The expander 73 passes through the bolt hole and enters the welding nut 100. Then, it expands and fixes the welding nut 100 from the inside. It should be noted that the expander 73 is wrapped with a cleaning bag. When the expander 73 is inserted into the inside of the welding nut 100 and expands, the cleaning bag can absorb and clean the liquid, dust and other impurities inside the welding nut 100. After all the welding nuts 100 are fixed from the inside by the expander 73, the control clamp 5 drives the square tube 200 to move to the right. At this time, the expander 73 will drive the welding nuts 100 to move in the groove of the nut feeder 2, so that the welding nuts 100 are separated from the protrusion 2a and push the rotating plate 2b to flip downward. Then, the square tube 200 is no longer sleeved on the nut feeder 2, and the welding nuts 100 are restricted at the bolt hole (the position to be welded) by the expander 73. In this way, the present invention realizes the automation of transferring multiple welding nuts 100 to the bolt hole inside the square tube 200 through the cooperation of the nut feeder 2 and the expander 73, and restricts them so that the welding nuts 100 and the square tube 200 can move synchronously in the future, realizing the batch welding pre-feeding of welding nuts 100. Compared with the workers welding one welding nut 100 and then placing another welding nut 100, it has a great improvement in efficiency. Next, the two-axis moving platform 4 is controlled to move the clamp 5 and the square tube 200 forward, so that the left end of the square tube 200 is directly facing the lower electrode 1b. Then, the two-axis moving platform 4 is controlled to move the clamp 5 and the square tube 200 to the left, so that the square tube 200 is fitted onto the lower electrode 1b. Figure 8 , Figure 9 As shown, at this time, the leftmost welding nut 100 is inserted into the groove 1c of the lower electrode 1b and is directly facing the upper electrode 1a above, realizing the automatic feeding of the welding nut 100 on the lower electrode 1b. Then, the expander 73 is controlled to contract and no longer fix the inner side of the welding nut 100. Next, the telescopic part of the second pneumatic push rod 72 drives the expander 73 to move upward, and the first pneumatic push rod 71 drives the second pneumatic push rod 72 and the expander 73 to move backward, without blocking the upper electrode 1a from moving downward. Then, the upper electrode 1a is controlled to move downward, and the welding nut 100 is welded to the square tube 200 through the upper electrode 1a and the lower electrode 1b. After a welding nut 100 is welded to a square tube 200, the square tube 200 is moved to the left so that the next welding nut 100 is positioned directly below the upper electrode 1a for welding. This automates the welding of all welding nuts 100 inside the square tube 200 (at the bolt holes). It eliminates the need to expose the lower electrode 1b to place the welding nuts 100 during the welding process (which is inefficient as it requires exposing the lower electrode 1b for each welding nut 100). Furthermore, the expansion device 73 moves the welding nut 100 along with the square tube 200, ensuring that the welding nut 100 remains aligned with the bolt holes of the square tube 200 even when it enters the groove 1c of the lower electrode 1b, thus preventing welding deviations. It should be noted that, as Figure 9 As shown, after the welding nut 100 is welded to the square tube 200, the welding nut 100 moves with the square tube 200 and slides to the left in the groove 1c.

[0028] Example 2: Based on Example 1, as follows Figures 1-11 As shown, it also includes a smoke removal assembly 9, which includes a third pneumatic guide rail 91, a third pneumatic push rod 92, an air intake hood 93, and an air blowing hood 94; the third pneumatic guide rail 91 is fixedly connected to the lower side of the mounting bracket 6; the third pneumatic guide rail 91 has two moving parts, and a third pneumatic push rod 92 is fixedly connected to each of the two moving parts; the right side of the third pneumatic push rod 92 has an air intake hood 93 fixedly connected to its telescopic part, and an air intake device is connected to the first shielding part 93a of the air intake hood 93; the left side of the third pneumatic push rod 92 has an air blowing hood 94 fixedly connected to its telescopic part, and an air blowing device is connected to the second shielding part 94a of the air blowing hood 94, and the second shielding part 94a has a U-shaped through hole 94b, so that the second shielding part 94a can be fitted onto the outside of the lower electrode 1b.

[0029] like Figure 5 As shown, it also includes an air blower 74 and a connecting rod 75; the air blower 74 is fixedly connected to the telescopic part of the second pneumatic push rod 72, and the air blower 74 has a downward blowing port; the bottom of the air blower 74 is fixedly connected to a connecting rod 75 with a radius smaller than the bolt hole of the square tube 200, and the connecting rod 75 is fixedly connected to the expander 73.

[0030] When welding the welding nut 100 to the square tube 200, fumes are generated. These fumes affect the air quality of the factory, and they also adhere to the inside of the welding nut 100, so they need to be removed. Specifically, before welding the square tube 200 onto the lower electrode 1b, if... Figure 11As shown, by controlling the moving part of the third pneumatic guide rail 91, the third pneumatic push rod 92 is driven to move left and right. The third pneumatic push rod 92 drives the suction hood 93 and the blowing hood 94 to move forward, so that the suction hood 93 is fitted onto the right side of the square tube 200 and the blowing hood 94 is fitted onto the left side of the square tube 200, as shown. Figure 8 , Figure 9 As shown, during welding, the left side of the square tube 200 is closed by the air blowing hood 94, and the right side of the square tube 200 is closed by the air suction hood 93. The air blowing device connected to the second shielding part 94a of the air blowing hood 94 blows air, and the air suction device connected to the first shielding part 93a of the air suction hood 93 sucks air, forming an airflow from left to right, which sucks away the welding fumes for subsequent processing. like Figure 10 As shown, at the same time, since the radius of the connecting rod 75 is smaller than the diameter of the bolt hole of the square tube 200, the air blower 74 can be controlled to blow air downward (to the bolt hole of the square tube 200) to avoid the smoke from staying at the welding nut 100, causing the smoke to adhere to the welding nut 100, and especially to prevent the smoke from entering the inner thread of the welding nut 100.
