Description

Technical Field

[0001] The utility model belongs to the technical field of steering column rear bracket assembly production equipment, in particular to a steering column rear bracket assembly welding device. Background Art

[0002] The automotive steering column assembly includes an upper column tube, a lower column tube, an upper steering shaft, a lower steering shaft, a front mounting bracket, and a rear mounting bracket. The upper end of the lower column tube is sleeved into the lower end of the upper column tube. The upper steering shaft is located within the upper column tube, while the lower steering shaft is located within the lower column tube. The upper and lower steering shafts are connected by a spline. The front mounting bracket is welded to the middle of the upper column tube, while the rear mounting bracket is welded to the lower column tube. Automatic welding equipment is primarily used for welding, but manual welding may be required for low-volume production of unpopular models.

[0003] When manually welding the rear mounting bracket, if the welding rod is too short, the welding point and the holding point are too close, and the temperature of the hand is too high during welding, so welders will often discard the welding rod that is too short, resulting in the problem of wasting welding rods when manually welding the rear mounting bracket with conventional welding clamps.

[0004] To this end, we propose a steering column rear bracket assembly welding equipment to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of wasting welding rods when manually welding and installing the bracket with conventional welding tongs, and proposes a steering column rear bracket assembly welding device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A welding device for a steering column rear bracket assembly includes a welding rod, a conductive clamp clamped to the top of the welding rod, a conductive slider fixedly connected to the top end of the conductive clamp, a handle and an elastic pressure piece clamped to the outside of the conductive slider, the front of the elastic pressure piece fixedly connected to the handle, the rear of the elastic pressure piece movable through the handle, a conductive block fixedly connected to the front of the handle, the conductive block pressed against the conductive slider, and the conductive block electrically connected to an external welding machine, and a first pinch button and a second pinch button fixedly connected to the bottom of the conductive clamp. When the welding rod is too short, pressing the elastic pressure piece causes it to release the conductive slider, causing the slider to slide down, thereby increasing the distance between the welding rod's weld point and the handle. This allows the welding rod to remain functional even when too short, reducing material waste.

[0008] Pinch the first and second pinch buttons to act on the conductive clamp, so that the lower part of the conductive clamp opens, thereby releasing the welding rod from the conductive clamp, removing the welding rod, and then inserting a new welding rod into the conductive clamp to facilitate replacement of the welding rod.

[0009] Preferably, a stopper is fixedly connected to the upper portion of the conductive slider, which blocks the upper side of the handle and the elastic pressure piece to prevent the conductive slider from sliding down excessively and falling off, thereby improving the stability of the installation relationship between the conductive slider, the handle and the elastic pressure piece.

[0010] Preferably, the grip includes a guide frame and a handle, wherein the rear end of the guide frame is fixedly connected to the front end of the handle. The guide frame is used to guide the sliding of the conductive slider, thereby improving the stability of the sliding direction of the conductive slider.

[0011] Preferably, the elastic pressure piece includes a spring piece, a push rod, and a button. The front portion of the push rod is fixedly connected to the guide frame, the spring piece is fixedly connected to the front portion of the push rod, and the button is fixedly connected to the rear portion of the push rod. The elastic force of the spring piece acts on the conductive slider, causing the slider to be clamped between the conductive block and the spring piece. Pressing the button, through which the button acts on the push rod, causes the push rod to drive the spring piece to release the conductive slider, causing the slider to slide downward, thereby increasing the distance between the lower end of the welding rod and the grip point.

[0012] Preferably, the conductive clamp includes a connecting block, a first elastic clip and a second elastic clip, wherein the first elastic clip and the second elastic clip are symmetrically fixedly connected to the lower portion of the connecting block, and the elastic force of the first elastic clip and the second elastic clip facilitates clamping the welding rod.

[0013] Preferably, the conductive clip further includes a pair of guide blocks, wherein one guide block is fixedly connected to the lower end of the second elastic clip, and the other guide block is fixedly connected to the lower end of the first elastic clip. The guide blocks facilitate guiding the welding rod to be inserted between the first elastic clip and the second elastic clip.

[0014] Preferably, the first pinch button includes a first pinch block and a squeeze bar, wherein the squeeze bar is symmetrically fixedly connected to the lower portion of the first pinch block. When the first pinch block is subjected to pressure, the squeeze bar acts on the second elastic clip, causing the second elastic clip and the first elastic clip to open, thereby facilitating the opening of the first and second elastic clips.

[0015] Preferably, the second pinch button includes a second pinch block and a pull block, wherein the lower end of the second pinch block is fixedly connected to the pull block. By manually pinching the second pinch block and the first pinch block, the pulling force at the lower portion of the second pinch block acts on the pull block, which in turn acts on the first elastic clip via the pull block, thereby facilitating the opening of the first elastic clip.

[0016] In summary, the technical effects and advantages of the utility model are:

[0017] 1. When the welding rod is too short, press the elastic pressure piece to release the conductive slider, causing the slider to slide down, increasing the distance between the welding point and the hand grip, so that the welding rod can still be used normally when it is too short, reducing material waste.

[0018] 2. Pinch the first and second pinch buttons so that they act on the conductive clamp, causing the lower part of the conductive clamp to open, thereby releasing the welding rod from the conductive clamp. Remove the welding rod, and then insert a new welding rod into the conductive clamp to facilitate replacement of the welding rod.

[0019] 3. Use the block to block the upper side of the handle and the elastic pressure piece to prevent the conductive slider from sliding down excessively and falling off, thereby improving the stability of the installation relationship between the conductive slider, the handle and the elastic pressure piece.

[0020] 4. Use the elastic force of the spring to act on the conductive slider so that the conductive slider is clamped between the conductive block and the spring. Press the button to act on the push rod through the button, so that the push rod drives the spring to loosen the conductive slider, causing the conductive slider to slide down, thereby increasing the distance between the lower end of the welding rod and the grip point.

[0021] 5. When the first pinching block is subjected to pressure, it acts on the second elastic clip through the extrusion bar, causing the second elastic clip and the first elastic clip to open, making it easier to open the first elastic clip and the second elastic clip.

[0022] 6. Pinch the second pinch block and the first pinch block by hand so that the pulling force at the bottom of the second pinch block acts on the pulling block, which acts on the first elastic clip through the pulling block, making it easier to open the first elastic clip.

[0030] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0031] A steering column rear bracket assembly welding device includes a welding rod 10, a conductive clip 4 is clamped on the upper part of the welding rod 10, the upper end of the conductive clip 4 is fixedly connected to a conductive slide 7, the outside of the conductive slide 7 is clamped with a handle 2 and an elastic pressure piece 3, the front part of the elastic pressure piece 3 is fixedly connected to the handle 2, the rear part of the elastic pressure piece 3 moves through the handle 2, the front part of the handle 2 is fixedly connected to a conductive block 9, the conductive block 9 is pressed on the conductive slide 7, the conductive block 9 is electrically connected to an external welding machine, and the lower part of the conductive clip 4 is fixedly connected to a first pinch button 5 and a second pinch button 6.

[0032] The upper portion of the conductive slide 7 is fixedly connected with a stopper 8. The stopper 8 is utilized to block the upper side of the handle 2 and the elastic pressing piece 3 to prevent the conductive slide 7 from excessively sliding down and falling off.

[0033] The handle 2 includes a guide frame 21 and a handle 22. The conductive slide 7 is slidably embedded in the guide frame 21. The conductive block 9 is fixedly connected to the inside of the guide frame 21. The rear end of the guide frame 21 is fixedly connected to the front end of the handle 22. The guide frame 21 is used to guide the conductive slide 7 to slide.

[0034] The elastic pressure piece 3 includes a spring piece 32, a push rod 31, and a button 33. The button 33 passes through the guide frame 21 and does not contact the guide frame 21. The front portion of the push rod 31 is fixedly connected to the guide frame 21, the spring piece 32 is fixedly connected to the front portion of the push rod 31, and the button 33 is fixedly connected to the rear portion of the push rod 31. The elastic force of the spring piece 32 acts on the conductive slider 7, clamping it between the conductive block 9 and the spring piece 32. Pressing the button 33, through which the button 33 acts on the push rod 31, causes the push rod 31 to drive the spring piece 32 to release the conductive slider 7, causing it to slide downward.

[0035] The conductive clamp 4 includes a connecting block 41, a first elastic clip 42, and a second elastic clip 43. The connecting block 41 is fixedly connected to the lower portion of the conductive slider 7. The first elastic clip 42 and the second elastic clip 43 are clamped to the upper portion of the welding rod 10. The first elastic clip 42 and the second elastic clip 43 are symmetrically fixedly connected to the lower portion of the connecting block 41. The elastic force of the first elastic clip 42 and the second elastic clip 43 is used to clamp the welding rod 10.

[0036] The conductive clamp 4 also includes a pair of guide blocks 44, one of which is fixedly connected to the lower end of the second elastic clip 43, and the other is fixedly connected to the lower end of the first elastic clip 42. The guide blocks 44 are used to guide the welding rod 10 to be inserted between the first elastic clip 42 and the second elastic clip 43.

[0037] The first pinch button 5 includes a first pinch block 51 and a squeeze bar 52. The squeeze bar 52 is movably mounted on the outer end of the first elastic clip 42. The end of the squeeze bar 52 facing away from the first pinch block 51 is fixedly connected to the second elastic clip 43. The squeeze bar 52 is symmetrically fixedly connected to the lower portion of the first pinch block 51.

The pull block 62 is fixedly connected to the first elastic clip 42, and the lower end of the second pinch block 61 is fixedly connected to the pull block 62. When the second pinch block 61 and the first pinch block 51 are pinched, the pulling force at the lower end of the second pinch block 61 acts on the pull block 62, which in turn acts on the first elastic clip 42 through the pull block 62.

[0039] Working Principle: When the welding rod 10 is too short, the elastic pressure piece 3 is pressed to release the conductive slide 7, causing it to slide downward, increasing the distance between the welding point of the welding rod 10 and the hand grip 2. This allows the welding rod 10 to be used normally even when it is too short, thereby reducing material waste. The first and second pinch buttons 5 and 6 are squeezed to act on the conductive clamp 4, causing the lower part of the conductive clamp 4 to open, thereby releasing the conductive clamp 4 from the welding rod 10. The welding rod 10 can then be removed and a new welding rod 10 can be inserted into the conductive clamp 4 to replace the welding rod 10.
