Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, specifically a calibration device for a nut welding machine. Background Technology

[0002] A nut welding machine is a specialized device for welding nuts onto metal parts, widely used in the production of automobiles, home appliances, and other metal products. Its main working principle is to use arc welding or resistance welding technology to firmly weld the nut to the workpiece. It can complete the welding quickly, making it suitable for mass production. By precisely controlling welding parameters, it ensures weld strength and quality. It is typically equipped with automated equipment to reduce manual operation and improve production efficiency. It can be used to weld nuts of different sizes and types, adapting to various industrial needs.

[0003] Currently, existing nut welding machines weld nuts to metal parts by feeding the nut onto the metal part and then lowering the welding head to weld the nut to the metal part. However, during welding, the nut is prone to shifting, resulting in inaccurate welding position and certain defects. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a calibration device for a nut welding machine. This device has the advantages of calibrating the welding position of the nut, improving the accuracy of the welding position, and solving the problem that the nut is prone to displacement when welding with metal parts, resulting in inaccurate welding position.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a calibration device for a nut welding machine, comprising a stabilizing component, a welding component, a feeding component, a platform component, a control component, a calibration component, and a driving component. The stabilizing component includes a stabilizing base plate, a support frame fixed on the stabilizing base plate, a mounting plate fixed on the support frame, and a welding component for welding nuts fixed on the mounting plate.

[0006] The support frame is equipped with a feeding assembly for conveying nuts.

[0007] A platform assembly for providing installation space for nuts is mounted on the stabilizing base plate, and a feeding assembly is located between the welding assembly and the platform assembly.

[0008] The platform component includes a platform plate set on a stable base plate, a base fixed on the platform plate, a connecting plate installed inside the base plate, an installation head installed on the connecting plate, a docking rod installed on the installation head, and a sleeve hole opened on the platform plate, the sleeve hole penetrating the platform plate and the connecting plate, and a control component for lifting and moving is movably fitted inside the sleeve hole.

[0009] The control assembly is equipped with a calibration component for adjusting and calibrating the welding position of the nut.

[0010] The bottom of the platform plate is fixed with a drive component for driving the control component to move up and down.

[0011] As a further improvement to the above solution, the welding assembly includes a welding machine fixed on the mounting plate, and a welding head is installed at the output end of the welding machine, with the welding head corresponding to the mounting head.

[0012] With the above technical solution, the welding machine is fixed vertically on the mounting plate, so that the welding head installed on the output end can correspond to the mounting head, and can perform welding on the nut when they are close to each other.

[0013] As a further improvement to the above solution, the feeding assembly includes an electric telescopic rod fixed on the support frame, a feeding head fixed at the output end of the electric telescopic rod, a feeding interface opened on the feeding head, the feeding interface passing through the bottom of the feeding head, and the feeding head located between the welding head and the mounting head.

[0014] Through the above technical solution, the feeding interface opened on the feeding head corresponds to the welding head and the mounting head, so that when the welding head descends and docks with the mounting head, the nut placed on the feeding head can be fed between the mounting head and the welding head for welding.

[0015] As a further improvement to the above solution, a connector is fixed to the bottom of the platform plate, and a connecting ring is rotatably connected to one end of the connector. An adjusting motor is installed on the connecting ring, and the adjusting motor is fixed to the stable base plate.

[0016] Through the above technical solution, the output end of the adjusting motor and the connector are connected to the fixed position by a connecting ring thread. When the adjusting motor is running, the output end drives the platform plate to rotate, thereby achieving the function of adjusting the angle.

[0017] As a further improvement to the above solution, the control component includes an adjusting rod that is movably sleeved in the sleeve hole, a sleeve rod fixed to one end of the adjusting rod, an extension rod movably sleeved on the sleeve rod, a connecting button fixed on the extension rod, and a connecting block threadedly connected to the connecting button.

[0018] Through the above technical solution, the connecting button and the connecting block are threaded together to realize the installation of the control component and the calibration component. When the control component moves up and down, the height of the calibration component can be adjusted. At the same time, the extension rod can move up and down on the side of the mounting rod, so that when the welding head pushes the nut down into the calibration component, the extension rod slides down on the side of the mounting rod until the nut is connected with the mounting head.

[0019] As a further improvement to the above solution, a tension spring is movably sleeved on the side of the sleeve rod, and the tension spring is attached between the adjusting rod and the extension rod.

[0020] Through the above technical solution, the tension spring is used to push the extension rod upward, so that the calibration component can provide stable support for the nut. When the welding head is released from the force against the nut, the tension spring pushes the extension rod, so that the calibration component moves upward and returns to the initial position.

[0021] As a further improvement to the above solution, the side of the adjusting rod is provided with a tooth profile, and the driving assembly includes a driving box fixed to the bottom of the platform plate. A driving motor is fixed inside the driving box, and a driving gear is fixed to the output end of the driving motor. The driving gear meshes with the tooth profile.

[0022] Through the above technical solution, the output end of the drive motor has the function of bidirectional rotation. The output end drives the drive gear to rotate in the forward or reverse direction, and under the action of meshing with the tooth profile on the adjusting rod, the function of controlling the lifting and lowering of the adjustment component is realized, that is, the height of the calibration component can be adjusted.

[0023] As a further improvement to the above solution, the calibration component includes a calibration ring fixed on the connecting block, and a number of retaining clamps are movably connected inside the calibration ring.

[0024] With the above technical solution, the retaining plates are evenly distributed and can clamp the sides of nuts of different diameters, thereby improving the stability of the nuts during welding.

[0025] As a further improvement to the above solution, a stabilizing rod is fixed to the rear side of the fixing clamp, and a thrust spring is fitted on the stabilizing rod. The stabilizing rod is movably sleeved inside the calibration ring, while one end of the thrust spring is attached to the calibration ring.

[0026] The above technical solution provides multiple slots within the calibration ring, and the retaining clamp is arc-shaped and fitted into the slot. The stability of the retaining clamp's movement is improved by the telescopic movement of the stabilizing rod within the slot. Simultaneously, the retaining clamp is clamped to the side of the nut by the thrust of the thrust spring.

[0027] As a further improvement to the above solution, a positioning rod is threadedly connected to the side of the connecting block, and one end of the positioning rod is attached to the side of the connecting button.

[0028] By using the above technical solution, the positioning rod is rotated so that its front end is pressed tightly against the side of the connecting button, thus fully fixing the connecting button and the connecting block.

[0029] Compared with the prior art, the present invention provides a calibration device for a nut welding machine, which has the following beneficial effects:

[0030] 1. The calibration device of this nut welding machine has a calibration component installed on the platform assembly. The drive assembly controls the lifting and moving of the adjustment component, so that the calibration ring is fitted on the side of the nut and lowers to the upper surface of the welding metal part. Then, the welding assembly welds the nut inside the calibration ring, which effectively improves the accuracy of the welding position.

[0031] 2. The calibration device of this nut welding machine has multiple fixed clamps evenly arranged in the calibration ring. When the control component rises to pick up the nut, the rebound force of the thrust spring can clamp the nut on nuts of different diameters. This allows for the calibration and fixed welding of nuts of different diameters, further improving the flexibility of the device. Attached Figure Description

[0049] Please see Figures 1-8 As shown, the calibration device for the nut welding machine proposed in this embodiment includes a stabilizing component 1, a welding component 4, a feeding component 5, a platform component 6, a control component 7, a calibration component 8, and a drive component 9.

The stabilizing base plate 101 is used to improve the overall stability of the device and to elevate the welding component 4 and the feeding component 5 through the support frame 102.

[0050] A feeding assembly 5 for conveying nuts is installed on the support frame 102.

[0051] A platform assembly 6 for providing installation space for nuts is installed on the stabilizing base plate 101.

At the bottom of head 502, the feeding head 502 is located between welding head 402 and mounting head 607. A connecting head 602 is fixed to the bottom of platform plate 601. One end of the connecting head 602 is rotatably connected to a connecting ring 603. An adjusting motor 604 is mounted on the connecting ring 603 and fixed to the stable base plate 101. The control assembly 7 includes an adjusting rod 701 movably sleeved within a sleeve hole 609. One end of the adjusting rod 701 is fixed to a sleeve rod 704. An extension rod 705 is movably sleeved on the sleeve rod 704. A fixed extension rod 705 is mounted on the extension rod 705. A connecting button 707 is fixed. The calibration assembly 8 includes a connecting block 801 threaded onto the connecting button 707. A tension spring 706 is movably sleeved on the side of the sleeve rod 704. The tension spring 706 fits between the adjusting rod 701 and the extension rod 705. The side of the adjusting rod 701 is provided with a tooth profile 703. Meanwhile, the drive assembly 9 includes a drive box 901 fixed to the bottom of the platform plate 601. A drive motor 902 is fixed inside the drive box 901. A drive gear 903 is fixed to the output end of the drive motor 902.

[0057] In this design, the welding machine 401 is vertically fixed on the mounting plate 103, allowing the welding head 402 mounted on the output end to correspond with the mounting head 607. When they approach each other, the welding head 402 can weld the nut. The feeding port 503 of the feeding head 502 corresponds to both the welding head 402 and the mounting head 607, allowing the nut placed on the feeding head 502 to be fed between the mounting head 607 and the welding head 402 for welding when the welding head 402 descends to align with the mounting head 607. The output end of the adjusting motor 604 is connected to the connector 602 via a connecting ring 603. The screw connection is fixed.

The connecting button 707 is screwed to the connecting block 801, enabling the installation of the adjusting component 7 and the calibration component 8. When the adjusting component 7 moves up and down, it adjusts the height of the calibration component 8. At the same time, the extension rod 705 can move up and down on the side of the mounting rod 704. When the welding head 402 pushes the nut downward into the calibration component 8, the extension rod 705 slides downward on the side of the mounting rod 704 until the nut aligns with the mounting head 607. The tension spring 706 is used to push the extension rod 705 upwards, enabling the calibration component 8 to provide stable support for the nut. When the welding head 402 disengages from the force resisting the nut, the tension spring 706 pushes the extension rod 705, causing the calibration component 8 to move upwards and return to its initial position. The output end of the drive motor 902 has a bidirectional rotation function, driving the drive gear 903 to rotate clockwise or counterclockwise. Under the force of the gear engaging with the tooth profile 703 on the adjusting rod 701, the lifting and lowering of the regulating component 7 is controlled, that is, the height of the calibration component 8 is adjusted and fixed. The clamping plates 804 are evenly distributed and can clamp the sides of nuts of different diameters, improving the stability of the nuts during welding. The calibration ring 803 has multiple slots. The fixing clamping plate 804 is arc-shaped and fits in the slot. The stabilizing rod 8041 moves telescopically in the slot, improving the stability of the moving of the fixing clamping plate 804. At the same time, the thrust of the thrust spring 8042 makes the fixing clamping plate 804 clamp the side of the nut. By rotating the positioning rod 802, the front end of the positioning rod 802 is pressed against the side of the connecting button 707, thus fully fixing the connecting button 707 and the connecting block 801.
