Description

Technical Field

[0001] This utility model belongs to the field of automotive welding clamp docking technology, specifically a vertical positioning docking device for automotive manufacturing welding clamp electrode caps. Background Technology

[0002] In the field of modern automobile manufacturing, the stability and safety performance of the car body are highly dependent on the quality of the welding process, among which the accuracy and consistency of automatic resistance welding points are one of the key factors. The body of a car is usually made up of about 5,000 weld points that are tightly connected. The quality of these weld points is directly related to the overall strength and durability of the car body. For modern models that use high-strength steel plates, it is particularly important to ensure that the electrode cap and the plate are perpendicular to each weld point, as this is a necessary condition for achieving high-quality welding, enhancing weld strength, preventing welding spatter, and improving the appearance of the weld points.

[0003] However, the methods commonly used in the industry at present mainly rely on the operator's visual judgment, auxiliary tools (such as set squares), or directly using the tin foil indentation marks to indirectly assess the perpendicularity of the electrode cap to the plate. These methods have significant limitations.

[0004] Visual judgment: It relies heavily on the operator's experience and eyesight, and is easily affected by fatigue, lighting conditions and individual differences, leading to inaccurate judgment of vertical angles with a large margin of error.

[0005] Auxiliary tools (such as set squares): Although they can improve the objectivity of judgment to some extent, they are cumbersome to operate, inefficient, and it is difficult to guarantee the consistency and accuracy of each measurement.

[0006] Tin foil indentation method: Although it can reflect the contact situation to a certain extent, it cannot directly measure the perpendicularity, and the indentation is easily affected by a variety of factors (such as the surface condition of the board, the shape of the electrode cap, etc.), resulting in results that are not intuitive and inaccurate.

[0007] To address this issue, those skilled in the art have proposed a vertical positioning and docking device for welding electrode caps in automotive manufacturing to solve the problems raised in the background art. Utility Model Content

[0008] To address the aforementioned technical problems, this utility model provides a vertical positioning and docking device for electrode caps in automotive manufacturing welding clamps, thereby solving the problem of difficulty in vertically and accurately welding electrode caps in the prior art.

[0009] A vertical positioning and docking device for welding electrode caps in automotive manufacturing includes: a calibration component; a limiting mechanism that is elastically slidably disposed on the side wall of the calibration component for vertically guiding the electrode cap; an adjusting mechanism disposed on the calibration component for adjusting the inner diameter of the calibration component; and a magnetic attraction mechanism disposed inside the calibration component for adsorbing and fixing the calibration component onto the workpiece.

[0010] Preferably, the limiting mechanism includes a plurality of limiting members that are elastically slidably disposed on the side wall of the calibration member, and the outer wall of the limiting members is engraved with calibration scale.

[0011] Preferably, a connecting block is fixedly provided at the top and bottom of the limiting member, a first restoring spring is fixedly provided at the top of the limiting member through the connecting block, and a second restoring spring is fixedly provided at the bottom of the limiting member through the connecting block; limiting slides are fixedly provided on both sides of the side wall of the limiting member.

[0012] Preferably, the adjustment mechanism includes a threaded annular groove formed on the side wall of the calibration component, and the calibration component is screwed with a threaded cap through the threaded annular groove; and the inner wall of the threaded cap is in contact with the outer wall of the limiting component.

[0013] Preferably, the magnetic attraction mechanism includes a magnetic block fixedly disposed inside the calibration component.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model has a magnetic block fixedly connected inside the calibration component, which gives the calibration component magnetic attraction and can be flexibly fixed at any position on the vehicle body. This ensures that when the electrode cap is positioned, it automatically reaches a vertical state when calibrating the inner wall through the calibration component, thus effectively solving the problems of low accuracy and cumbersome operation in traditional methods.

[0016] 2. This utility model uses a calibration component in conjunction with a metal component to fit a specific structure on the workpiece. Through fine-tuning, the calibration component and the workpiece are precisely positioned and calibrated. At the same time, the electrode cap is in close contact with the calibration component, and the angle of the electrode cap is accurate to ° during welding. This design concept is based on the coaxial principle, which improves the ease of operation, ensures the quality of welding, reduces welding spatter and appearance deformation, and significantly improves the precision and efficiency of automobile manufacturing.

[0017] 3. This utility model adjusts the inner diameter of the calibration piece by setting several limiting parts on the side wall of the calibration piece and pushing them with threaded caps. It can not only conveniently adjust the calibration piece to accommodate commonly used electrode caps of mm, mm and mm diameters with one calibration piece, but also steplessly adjust the inner diameter of the calibration piece according to actual needs. This achieves the purpose of convenient adjustment and use of the calibration piece to accommodate electrode caps of different sizes. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides a vertical positioning and docking device for welding electrode caps in automobile manufacturing, comprising: a calibration component 1; a limiting mechanism, elastically slidably disposed on the side wall of the calibration component 1, for vertically guiding the electrode cap; an adjusting mechanism disposed on the calibration component 1, for adjusting the inner diameter of the calibration component 1; and a magnetic attraction mechanism disposed inside the calibration component 1, for adsorbing the calibration component 1 onto the workpiece for fixation.

[0029] refer to Figure 1 The limiting mechanism includes a limiting component 2, a calibration scale 9, and a limiting slide bar 8;

[0030] By elastically sliding several limiting members 2 on the side wall of the calibration component 1, and setting several limiting members 2 in a ring shape to slide on the side wall of the calibration component 1, the inner diameter of the calibration component 1 can be adjusted by the ring sliding of several limiting members 2 during the use of the calibration component 1. This facilitates the vertical positioning of electrode caps of different sizes by adjusting the inner diameter of the calibration component 1 in conjunction with several limiting members 2, and facilitating the vertical positioning of electrode caps of different sizes, thus achieving the purpose of easy adjustment and use.

[0031] Meanwhile, connecting blocks 7 are fixedly connected to the top and bottom of the limiting member 2, and a first restoring spring 6 is fixedly connected to the top of the limiting member 2 via the connecting blocks 7, and a second restoring spring 10 is fixedly connected to the bottom of the limiting member 2 via the connecting blocks 7. This allows the limiting members 2 to maintain elasticity and slide towards the outer wall of the calibrator 1 through the first restoring spring 6 and the second restoring spring 10 when connected to the side wall of the calibrator 1. This prevents the limiting members 2 from sliding towards the inner wall of the calibrator 1, which would cause inaccurate dimensions when adjusting the inner diameter of the calibrator 1. Furthermore, limiting slide strips 8 are fixedly connected to both sides of the side wall of the limiting member 2, so that the limiting member 2 is limited by the two limiting slide strips 8 when sliding, thus preventing the limiting member 2 from sliding off course during adjustment.

[0032] Example 2:

[0033] refer to Figure 1 The adjusting mechanism includes a threaded annular groove 3 and a threaded cap 4;

[0034] By providing a threaded annular groove 3 on the side wall of the calibration piece 1, the calibration piece 1 can be easily screwed into a threaded cap 4 through the threaded annular groove 3, and the inner wall of the threaded cap 4 is fitted with the outer wall of several limiting pieces 2. When the threaded cap 4 is screwed up through the threaded annular groove 3, it can achieve the purpose of squeezing and pushing the limiting pieces 2. In this way, the inner wall diameter of the calibration piece 1 can be adjusted by sliding several limiting pieces 2, so as to adapt to the vertical docking of different electrode caps.

[0035] Meanwhile, the outer wall of the limiting member 2 is engraved with a scale 9, so that when the threaded cap 4 is screwed and adjusted through the threaded ring groove 3, it can adjust the sliding distance of several limiting members 2 by comparing with the scale 9, thereby adjusting the inner diameter of the calibration member 1 by several limiting members 2. Moreover, the screwing connection structure between the threaded ring groove 3 and the threaded cap 4 has self-locking properties, so that after the threaded cap 4 slides and adjusts through the threaded ring groove 3 on the outer wall of the calibration member 1, it can be firmly fixed for use, thereby achieving the purpose of the threaded cap 4 being able to stably adjust the inner diameter of the calibration member 1 through several limiting members 2.

[0036] Secondly, the outer diameter of the electrode cap is mainly in three sizes: 13mm, 16mm and 20mm. Therefore, the inner diameter formed by adjusting several limiting parts 2 through the threaded cap 4 can be adjusted to these three inner diameters by comparing with the scale 9. Other inner diameters can also be conveniently adjusted according to actual needs.

[0037] refer to Figure 1 The magnetic attraction mechanism includes a magnetic block 5;

[0038] A magnetic block 5 is fixedly connected inside the calibration component 1, which enables the bottom of the calibration component 1 to have magnetic attraction. When the calibration component 1 is placed on the workpiece and positioned and docked with the electrode cap, it can be quickly attracted and fixed to the workpiece by the magnetic block 5, which has the advantage of quickly determining the welding position.

[0039] Meanwhile, when positioning and docking on a workpiece with an uneven surface, the magnetic block 5 can be used to attract the metal sheet, and then the magnetic block 5 can be attached to the position of the workpiece to be welded after passing through the metal sheet pad, so as to ensure that the calibration piece 1 is in a vertical state, and docking and positioning can be performed in conjunction with the electrode cap.

[0040] Working Principle: Several limiting elements 2 are elastically slidably connected to the side wall of the calibration component 1, and these limiting elements 2 are arranged in a ring shape to slide and connect to the side wall of the calibration component 1. This allows for adjustment of the inner diameter of the calibration component 1 during use, facilitating vertical positioning of electrode caps of different sizes. The calibration component 1, in conjunction with the limiting elements 2, allows for vertical positioning and alignment with electrode caps of different sizes, facilitating adjustment and use. Simultaneously, the outer wall of the limiting elements 2 is engraved with a calibration scale 9, allowing the threaded cap 4 to be adjusted by comparing with the calibration scale 9 when screwed into the threaded groove 3. The sliding distance of the limiting component 2 is used to adjust the inner diameter of the calibration component 1 by changing the size of the inner diameter through the limiting component 2. The screw-in connection structure between the threaded ring groove 3 and the threaded cap 4 has self-locking property, so that after the threaded cap 4 slides and adjusts on the outer wall of the calibration component 1 through the threaded ring groove 3, it can be firmly fixed for use. This achieves the purpose of the threaded cap 4 being able to stably adjust the inner diameter of the calibration component 1 through the limiting component 2. Secondly, a magnetic block 5 is fixedly connected inside the calibration component 1, so that the bottom of the calibration component 1 has magnetic attraction ability. When the calibration component 1 is placed on the workpiece and positioned and docked with the electrode cap, it can be quickly attracted and fixed on the workpiece by the magnetic block 5, which has the advantage of quickly determining the welding position.
