Description

Technical Field

[0001] This utility model relates to the technical field of testing fixtures, and more specifically to a leak-proof testing spot welding fixture. Background Technology

[0002] Anti-collision beams are an important component of automotive protection systems. Their cross-section is usually concave, which allows them to be squeezed and deformed when a car is involved in a collision, absorbing the impact.

[0003] Anti-collision beams typically have multiple mounting holes machined into them. These holes are used to bolt the beam to the vehicle body, thus assembling the anti-collision beam relative to the car. Clearly, the accuracy of the mounting hole positions directly affects the assembly precision of the anti-collision beam and the car. Therefore, before the anti-collision beam leaves the factory, it is necessary to inspect for any missing points in the mounting holes and to verify their positional accuracy. However, considering the considerable length of the anti-collision beam and the large number of mounting holes spaced apart, if an external object accidentally bumps the anti-collision beam, causing it to become misaligned, inaccurate inspections of the mounting holes at other locations may occur. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when existing testing institutions inspect the assembly holes of crash beams, if the crash beam is accidentally bumped by external forces and its position is deviated, the inspection of some assembly holes may be inaccurate.

[0005] To address the aforementioned problems, this utility model provides a leak-proof spot welding fixture, comprising a base, a clamping platform and a detection assembly on the base, the clamping platform having a resting portion for fixing the workpiece, and the detection assembly comprising a linear drive, an adapter frame, a limiting pad and a detector. The linear drive is vertically disposed on the base and adjacent to the clamping platform. The adapter frame includes a receiving end connected to the linear drive, an intermediate section extending from the receiving end to the clamping platform, and a detection end bent downward from the intermediate section to above the resting portion. The detector is connected to the detection end of the adapter frame, and the limiting pad is detachably connected to the lower side of the detection end of the adapter frame.

[0006] In the above scheme, workpieces such as anti-collision beams are placed on the support part of the clamping platform with their concave surfaces facing upwards to achieve basic fixation. At the same time, by setting up a detection component, the adapter frame is raised and lowered by a linear drive component. When the adapter frame descends, the detection end can enter the interior of the anti-collision beam, so that the limiting pad abuts against the bottom surface of the concave part of the anti-collision beam, thereby further fixing the workpiece and preventing the anti-collision beam from being offset by collision. At the same time, the detector at the detection end can enter the interior of the anti-collision beam to detect whether there are any leaks in the assembly holes and whether the position is accurate, thereby achieving a more accurate detection effect.

[0007] In an improved embodiment, the detection assembly further includes a receiving block, the output end of the linear drive is positioned upward and connected to the receiving block, receiving members are provided on both sides of the receiving block, and the adapter end of the adapter frame has two parallel and spaced ear plates forming a U-shape, the two ear plates are respectively attached to both sides of the receiving block and connected to the receiving members, thereby realizing the connection between the linear drive and the adapter end of the adapter frame through the receiving block.

[0008] In an improved embodiment, the receiving element is a square pin, and the two ear plates are respectively provided with square holes that fit into the receiving element. Thus, by pulling the two ear plates apart, aligning the square holes with the square pin, and then releasing the ear plates, the square holes fit into the square pin, thereby fixing the ear plates and the receiving block together.

[0009] In an improved embodiment, the adapter is made of plastic, which is not only low in cost, but also automatically breaks if the load on the adapter is too large when the linear drive malfunctions or the workpiece is placed incorrectly on the clamp, thus preventing damage to the linear drive or the workpiece.

[0010] In an improved embodiment, the clamping platform includes a main limiting block for supporting the bottom surface of the workpiece, and a left limiting block and a right limiting block located on the left and right sides of the main limiting block, respectively. The left limiting block and the right limiting block are used to limit the contact with the left and right sides of the workpiece, respectively.

[0011] In an improved embodiment, the base is provided with a bracket located between the base and the linear drive, and the bracket is detachably connected to a positioning block located below the adapter. When the linear drive causes the adapter to descend so that the limiting pad abuts against the upper side of the workpiece, the middle section of the adapter abuts against the positioning block, thereby limiting the lowest point of the adapter's stroke through the positioning block and preventing damage to the workpiece.

[0012] In an improved embodiment, the upper part of the positioning block is provided with a positioning groove corresponding to the adapter frame, thereby ensuring that the positioning block can be better abutted by the middle section of the adapter frame through the positioning groove.

[0013] In an improved embodiment, the detector is a proximity switch.

[0014] In an improved solution, the limiting pad is made of rubber, which provides better deformation capability and avoids damage to the workpiece. Attached Figure Description

[0026] Please see Figures 1-5 An embodiment of this utility model provides a leak-proof spot welding fixture, including a base 1, a clamping platform 2 and a detection component 3 on the base 1. The clamping platform 2 has a resting part for fixing the workpiece. The detection component 3 includes a linear drive 31, an adapter frame 32, a limiting pad 33 and a detector 34. The linear drive 31 is vertically arranged on the base 1 and adjacent to the clamping platform 2. The adapter frame 32 includes a receiving end 32a connected to the linear drive 31, an intermediate section 32b extending from the receiving end 32a to the clamping platform 2, and a detection end 32c bent downward from the intermediate section 32b to above the resting part. The detector 34 is connected to the detection end 32c of the adapter frame 32. The limiting pad 33 is detachably connected to the lower side of the detection end 32c of the adapter frame 32.

[0027] In the above scheme, the workpieces such as the anti-collision beam are placed on the resting part of the clamping platform 2 with the concave side facing upward to achieve basic fixation. At the same time, by setting the detection component 3, the linear drive component 31 drives the adapter frame 32 to rise and fall. When the adapter frame 32 descends, the detection end 32c can enter the interior of the anti-collision beam, so that the limiting pad 33 abuts against the bottom surface of the concave part of the anti-collision beam, thereby further fixing the workpiece and preventing the anti-collision beam from being offset by collision. At the same time, the detector 34 of the detection end 32c can enter the interior of the anti-collision beam to detect whether the assembly hole has leaks or whether the position is accurate, thereby achieving a more accurate detection effect.

[0028] In this embodiment, the detection component 3 further includes a receiving block 35. The output end of the linear drive 31 is upwardly positioned and connected to the receiving block 35. Receiving members 351 are provided on both sides of the receiving block 35. The adapter end of the adapter frame 32 has two parallel and spaced ear plates 321 forming a U-shape. The two ear plates 321 are respectively attached to both sides of the receiving block 35 and connected to the receiving members 351, thereby achieving the connection between the linear drive 31 and the adapter end of the adapter frame 32 through the receiving block 35. The linear drive 31 is preferably a cylinder or an electric cylinder. The cylinder body of the linear drive 31 is connected to the base 1, and the cylinder rod of the linear drive 31 is upwardly positioned and connected to the receiving block 35.

[0029] The receiving component 351 is specifically a square pin. Two ear plates 321 each have square holes 321a that fit into the receiving component 351. By pulling the two ear plates 321 apart, aligning the square holes 321a with the square pin, and then releasing the ear plates 321, the square holes 321a fit into the square pin, thus fixing the ear plates 321 to the receiving block 35. Alternatively, the receiving component 351 can also be a bolt. The ear plates 321 have screw holes, allowing for a screw connection between the receiving block 35 and the adapter end of the adapter frame 32.

[0030] In this embodiment, the adapter 32 is made of plastic, which is not only low in cost, but also automatically breaks if the load on the adapter 32 is too large when the linear drive 31 malfunctions or the wrong workpiece is placed on the clamp 2, thus avoiding damage to the linear drive 31 or the workpiece.

[0031] In this embodiment, the clamping platform 2 includes a main limiting block 21 for supporting the bottom surface of the workpiece, and a left limiting block 22 and a right limiting block 23 located on the left and right sides of the main limiting block 21, respectively. The left limiting block 22 and the right limiting block 23 are used to achieve abutment and limiting of the left and right sides of the workpiece, respectively.

[0032] As an improvement to this embodiment, the base 1 is provided with a bracket 11 located between the base 1 and the linear drive 31. The bracket 11 is detachably connected to a positioning block 12 located below the adapter 32. When the linear drive 31 drives the adapter 32 to descend so that the limiting pad 33 abuts against the upper side of the workpiece, the middle section 32b of the adapter 32 abuts against the positioning block 12, thereby limiting the lowest point of the travel of the adapter 32 through the positioning block 12 to prevent damage to the workpiece.

[0033] Furthermore, the upper part of the positioning block 12 is provided with a positioning groove 12a corresponding to the adapter 32, thereby ensuring that the positioning block 12 can be better abutted by the middle section 32b of the adapter 32 through the positioning groove 12a.

[0034] In this embodiment, the detector 34 is a proximity switch. When the position of the detector 34 is the mounting hole of the anti-collision beam, the signal is 0, and when the position of the detector 34 is not the mounting hole, the signal is 1.

[0035] In this embodiment, the limiting pad 33 is made of rubber, which provides good deformation capability and avoids damage to the workpiece.
