Description

Technical Field

[0001] The present invention relates to a welding apparatus, and more specifically, to an automated welding apparatus for bases and shaft-type parts. Background Technology

[0002] Currently, sensor products are composed of complex structural parts. During the production process, complex parts (such as bases) and shaft parts (such as sleeves) need to be welded. Existing welding operations are carried out manually, which incurs high labor costs and requires highly skilled personnel. In addition, manual welding has low precision, takes a long time, and it is difficult to ensure consistent welding quality, resulting in low work efficiency. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides an automated welding device for bases and shaft parts, which can realize the automatic welding of bases and shaft workpieces, which is beneficial to improving welding accuracy and work efficiency and reducing labor costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automated welding device for bases and shaft parts, including a worktable, a rotary disk rotatably mounted on the worktable, a lifting disk that can be lifted and lowered on the worktable, and a clamping mechanism. A movable welding torch is mounted on the rotary disk, the lifting disk is used to load the base, and the clamping mechanism is used to clamp the shaft parts.

[0005] During welding, the shaft-like part is clamped onto the clamping mechanism, the base is fed to the lifting plate, the lifting plate rises to support the base, and the clamping mechanism moves up and down to bring the welding position on the base into contact with the lower end of the shaft-like part. The welding torch is moved so that its tip is close to the welding position, and the rotating plate rotates to perform welding. After welding is completed, the clamping mechanism disengages from the shaft-like part, and the welded product can be removed. The welding device of this invention can realize automatic welding of the base and the shaft-like workpiece, which is beneficial to improving welding accuracy and work efficiency, and reducing labor costs.

[0006] Preferably, the clamping mechanism includes a clamping base and two clamping arms connected to the clamping base. The clamping base is provided with a clamping groove for loading shaft-type workpieces, and the two clamping arms are respectively hinged to both sides of the clamping groove for clamping shaft-type parts.

[0007] Shaft-type parts are loaded in the clamping slot and clamped and positioned by the clamping arms, ensuring stable and reliable clamping.

[0008] Preferably, a connecting block is provided on the clamping base corresponding to the clamping arm, a positioning groove is formed between the connecting block and the clamping base, the clamping arm passes through the positioning groove, a positioning spring is installed between the clamping arm and the connecting block, and a connecting pin is connected between the clamping arm and the connecting block.

[0009] Under the action of the positioning spring, one end of the clamping arm abuts against the outer wall of the shaft part to position it. Pressing the other end of the clamping arm opens the clamping ends of both arms outward, thus separating the shaft part from the clamping mechanism, making the operation convenient.

[0010] Preferably, the clamping arms are provided with clamping protrusions, and the clamping protrusions on the two clamping arms protrude from the surface of the clamping arms in a direction that brings them closer to each other. The ends of the clamping protrusions are provided with arc-shaped clamping surfaces.

[0011] The inclusion of clamping protrusions increases the contact area between the clamping arms and shaft-like parts, improving the clamping effect. The curved clamping surface fits well against the outer wall of the shaft-like parts, ensuring effective clamping.

[0012] Preferably, the workbench is provided with a support, and a lifting seat that can be raised and moved is installed on the support, with the clamping mechanism installed on the lifting seat.

[0013] The lifting seat moves up and down on the support, with a simple structure and reliable operation.

[0014] Preferably, the support is provided with several slide rails, and the lifting seat is equipped with slide blocks corresponding to the slide rails, with the slide blocks being fitted onto the slide rails.

[0015] During the movement of the lifting platform, the slide block slides along the slide rail, ensuring precision and reliability.

[0016] Preferably, a support is mounted on the rotary table, an adjusting seat that can move along the Z-axis is mounted on the support, a moving seat that can move along the Y-axis is mounted on the adjusting seat, a transverse moving seat that can move along the X-axis is mounted on the moving seat, and a tilting fine-tuning piston cylinder is mounted on the transverse moving seat. The telescopic rod of the fine-tuning piston cylinder is connected to the welding torch.

[0017] Before welding, the position of the welding torch is coarsely adjusted by moving the Z-axis of the adjusting seat, the Y-axis of the moving seat, and the X-axis of the transverse moving seat. After the shaft-like parts and the base make contact at the welding position, the position of the welding torch is finely adjusted by the fine-tuning piston cylinder to bring the tip of the welding torch closer to the welding position. Then, the welding torch rotates with the rotary table while automatically welding the welding position.

[0018] Preferably, a lifting piston cylinder is installed on the worktable, the upper end of the extension rod of the lifting piston cylinder is connected to the lifting plate, and the rotating plate has a ring structure and is fitted outside the lifting plate.

[0019] The lifting plate is moved up and down by a lifting piston cylinder, which is simple in structure and reliable in operation. The rotating plate is sleeved outside the lifting plate to avoid interference during rotation.

[0020] Preferably, a positioning block is installed on the upper part of the clamping base, and a positioning groove is provided on the positioning block corresponding to the clamping groove. A stepped surface is provided on the side wall of the positioning groove, and two arc-shaped conductive strips are installed on the stepped surface. An attitude adjustment motor and an attitude adjustment roller are installed on the clamping arm. The attitude adjustment motor drives the attitude adjustment roller to rotate, and the outer wall of the attitude adjustment roller is in contact with the outer wall of the shaft workpiece. A proximity sensor is installed in the clamping groove. The attitude adjustment motor is electrically connected to the controller. The proximity sensor and the two conductive strips are all electrically connected to the controller.

[0021] After a shaft-like part is clamped into the clamping slot, it is detected by a proximity sensor. If the clamping is in place, the upper end of the shaft-like part is precisely against the stepped surface, and the stepped surface positions the shaft-like part. At this time, the shaft-like part electrically connects the two conductive strips on the stepped surface. The controller receives this signal, and the attitude adjustment motor does not start. However, often after the shaft-like part is clamped, it cannot reach a precise position; there is a certain gap between the upper end of the shaft-like part and the stepped surface. When the controller detects that the two conductive strips are not electrically connected, the attitude adjustment motor starts, and the attitude adjustment roller rotates, pushing the shaft-like part closer to the stepped surface. When the shaft-like part is in place, its upper end is against the stepped surface, and the shaft-like part electrically connects the two conductive strips on the stepped surface. The controller receives this signal, and the attitude adjustment motor stops. This structural design enables automatic attitude adjustment of shaft-like parts, ensuring accurate and reliable clamping position.

[0022] Preferably, a buffer pad is installed on the outer wall of the attitude adjustment roller. The buffer pad increases friction, ensuring that the attitude adjustment roller can move the shaft-like parts when it rotates. Moreover, the surface of the buffer pad is slightly higher than the clamping surface. When the clamping arm clamps the shaft-like parts, the buffer pad undergoes a certain deformation, ensuring that the buffer pad fits against the outer wall of the shaft-like parts and preventing slippage during rotation.

[0023] Compared with the prior art, the beneficial effects of the present invention are: (1) The welding device of the present invention can realize the automatic welding of the base and shaft workpiece, which is conducive to improving the welding accuracy and work efficiency and reducing labor costs; (2) The clamping mechanism can realize the automatic posture adjustment operation of shaft parts, ensuring that the clamping position of shaft parts is accurate and reliable.

[0031] The technical solution of the present invention will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0032] Example 1: An automated welding device for bases and shaft-type parts (see appendix) Figure 1 To be continued Figure 4 The system includes a worktable 1, a rotary disk 2 rotatably mounted on the worktable, a lifting disk 3 liftable and height-adjustable mounted on the worktable, and a clamping mechanism 4.

[0033] The clamping mechanism includes a clamping base 12 and two clamping arms 13 connected to the clamping base. The clamping base has clamping grooves 14 for loading shaft-type workpieces, and the two clamping arms are respectively hinged to both sides of the clamping grooves for clamping shaft-type parts. Connecting blocks 15 are provided on the clamping base and corresponding to the clamping arms, forming a positioning groove 16 between the connecting blocks and the clamping base. The clamping arms pass through the positioning groove, and positioning springs 17 are installed between the clamping arms and the connecting blocks. A pin 18 connects the clamping arms and the clamping base. The clamping arms and the clamping base are hinged by the pin. Both ends of the connecting blocks have protrusions 19 with grooves 20. The two ends of the pin are respectively installed in the grooves on the two protrusions. The clamping arms have hinge holes through which the pin passes. Clamping protrusions 21 are provided on the clamping arms, located at the ends of the clamping arms. The clamping protrusions on the two clamping arms protrude from the surface of the clamping arms in a direction that brings them closer together, and the ends of the clamping protrusions have arc-shaped clamping surfaces 22. A positioning block 23 is installed on the upper part of the clamping base. A positioning groove 24 is provided on the positioning block and corresponding to the clamping groove. A stepped surface 25 for positioning the upper end face of the shaft part is provided on the side wall of the positioning groove.

[0034] The workbench is equipped with a support 26, on which a lifting seat 27 is mounted for lifting and moving. A clamping mechanism is detachably mounted on the lifting seat. The support has several slide rails 28, and corresponding slide seats 29 are mounted on the lifting seat and mounted on the slide rails. A lifting screw driven by a motor is mounted on the support, and a lifting screw sleeve is fitted and connected to the lifting seat.

[0035] A support base 30 is mounted on the rotary table. An adjusting base 31, which can move along the Z-axis, is mounted on the support base. A movable base 32, which can move along the Y-axis, is mounted on the adjusting base. A transverse base 33, which can move along the X-axis, is mounted on the movable base. A tilting fine-tuning piston cylinder 34 is mounted on the transverse base. The telescopic rod of the fine-tuning piston cylinder is connected to the welding torch. Both the fine-tuning piston cylinder and the lifting piston cylinder are pneumatic cylinders.

[0036] A guide rod and a manual screw are installed on the support base. Both the guide rod and the manual screw are connected to the adjusting base. The upper end of the manual screw is connected to a turntable 35, and a handle 36 is connected to the turntable. An adjusting guide rail and an adjusting screw are installed on the adjusting base. The moving base is slidably connected to the adjusting guide rail. The adjusting screw is adapted to the moving base. A knob 37 is connected to one end of the adjusting screw for turning it. A transverse guide rail and a transverse screw are installed on the moving base. The transverse base is slidably connected to the transverse guide rail. The transverse screw is adapted to the transverse base. A knob is connected to one end of the transverse screw for turning it.

[0037] During welding, the shaft-like part is clamped onto the clamping mechanism, the base is fed to the lifting plate, the lifting plate rises to support the base, and the clamping mechanism moves up and down to bring the welding position on the base into contact with the lower end of the shaft-like part. The welding torch is moved so that its tip is close to the welding position, and the rotating plate rotates to perform welding. After welding is completed, the clamping mechanism disengages from the shaft-like part, and the welded product can be removed. The welding device of this invention can realize automatic welding of the base and the shaft-like workpiece, which is beneficial to improving welding accuracy and work efficiency, and reducing labor costs.

[0038] Example 2: An automated welding device for bases and shaft-type parts (see appendix) Figure 5 Appendix Figure 6 The structure is similar to that of Embodiment 1, with the main difference being that a positioning block is installed on the upper part of the clamping base in this embodiment. A positioning groove is provided on the positioning block corresponding to the clamping slot. A stepped surface is provided on the side wall of the positioning groove, and two arc-shaped conductive strips 38 are installed on the stepped surface, spaced apart. The positioning block is made of insulating material. An attitude adjustment motor 39 and an attitude adjustment roller 40 are installed on the clamping arm. An installation slot 41 is provided on the clamping protrusion, and both the attitude adjustment motor and the attitude adjustment roller are installed in the installation slot. The output shaft of the attitude adjustment motor is connected to the attitude adjustment roller, driving the roller to rotate. The outer wall of the attitude adjustment roller has an inwardly concave arc structure, and a buffer pad is installed on the outer wall of the roller, which fits against the outer wall of the shaft-like workpiece. A proximity sensor is installed in the clamping slot, and the attitude adjustment motor is electrically connected to the controller. The proximity sensor and the two conductive strips are also electrically connected to the controller. Other structures are the same as in Embodiment 1.

[0039] After the shaft-like part is clamped into the clamping slot, it is detected by the proximity sensor. If the clamping is in place, the upper end of the shaft-like part is exactly against the stepped surface, and the stepped surface positions the shaft-like part. Since the shaft-like part is a metal component and conductive, it electrically connects the two conductive strips on the stepped surface. The controller receives this signal, and the attitude adjustment motor does not start. However, often after the shaft-like part is clamped, it cannot reach a precise position; there is a certain gap between the upper end of the shaft-like part and the stepped surface. When the controller detects that the two conductive strips are not electrically connected, the attitude adjustment motor starts, and the attitude adjustment roller rotates, pushing the shaft-like part closer to the stepped surface. When the shaft-like part is in place, its upper end is against the stepped surface, and it electrically connects the two conductive strips on the stepped surface. The controller receives this signal, and the attitude adjustment motor stops. This structural design enables automatic attitude adjustment of shaft-like parts, ensuring accurate and reliable clamping position.
