Description

Technical Field

[0001] The utility model relates to the technical field related to oil cup production equipment, in particular to an oil cup welding auxiliary structure and oil cup production equipment. Background Art

[0002] The oil cup is used to store the oil dirt generated during the operation of the range hood. Most of the existing oil cups are hung on the range hood body through a hook. The hook is usually formed by bending the oil cup body, and the hook needs to be welded and fixed to the oil cup body to increase the reliability of the hook.

[0003] Currently, when welding the oil cup hook, the operator needs to manually align and fit the hook and the oil cup body at the welding position before the subsequent welding operation can be carried out. On the one hand, the operation remains unchanged and the welding efficiency is low. On the other hand, the alignment and fitting operation completely relies on the operator's experience, resulting in relatively poor dimensional stability of the hook welding position and no guarantee of product quality. In severe cases, the oil cup may even be unable to be installed due to excessive offset of the hook welding position. Utility Model Content

[0004] Based on this, it is necessary to provide an oil cup welding auxiliary structure and oil cup production equipment that can effectively improve the welding efficiency and dimensional stability of the oil cup hook in order to address the current problems of low welding efficiency and poor dimensional stability of the oil cup hook.

[0006] The welding tool comprises a base plate, a connecting piece and a positioning block, wherein the positioning block is fixed relative to the base plate by the connecting piece to form a gap between the positioning block and the base plate;

[0007] The oil cup includes an oil cup body and a hook portion formed by bending, the oil cup body is provided with a receiving cavity, one of the side walls of the oil cup body is inserted into the gap, so that the positioning block is located inside the receiving cavity and abuts against the bottom wall of the receiving cavity;

[0008] The positioning block is fixed with a positioning bar extending along the X-axis direction, and one end of the positioning bar close to the hook portion along the X-axis direction has a chamfer. When the positioning bar and the hook portion are against each other along the Y-axis direction, the hook portion is opposite to the position to be welded of the oil cup body.

[0009] In one embodiment, the connecting member includes a column and a connecting plate, one end of the column along the Z-axis direction is fixed to the base plate, the connecting plate is fixed to the column, and the positioning block is fixed to the end of the connecting plate along the X-axis direction.

[0010] In one embodiment, the connecting plate is detachably fixed to the column, and the positioning block is detachably fixed to the connecting plate.

[0011] In one of the embodiments, a positioning block is fixed to each of the two ends of the connecting plate along the X-axis direction.

[0012] In one embodiment, a plurality of positioning strips are fixedly disposed on the positioning block.

[0013] In one of the embodiments, when the positioning strips and the hook portion abut against each other along the Y-axis direction, at least one of the positioning strips is directly opposite to the position to be welded of the hook portion along the Y-axis direction.

[0014] In one embodiment, at least one of the positioning strips extends along the X-axis direction to an end of the positioning block close to the hook portion.

[0015] In one embodiment, the positioning bar includes a Y-direction limiting portion and an X-direction limiting portion, the chamfer is located at the Y-direction limiting portion, and when the X-direction limiting portion and the hook portion are against each other along the X-axis direction, the Y-direction limiting portion and the hook portion are against each other along the Y-axis direction.

[0016] In one embodiment, the projection of the positioning bar along the Z-axis direction is U-shaped, wherein the bottom of the U-shape is the X-direction limiting portion, the opening of the U-shape faces the hook portion, and the Y-direction limiting portion on one side is fixed to the positioning block.

[0017] A second aspect of the present application provides an oil cup production device, comprising the above-mentioned oil cup welding auxiliary structure.

[0018] The above-mentioned oil cup welding auxiliary structure, by setting the welding fixture, the operator only needs to slide the oil cup relative to the bottom plate along the X-axis direction to make the chamfer on the positioning block contact with the hook part, and as the oil cup moves further, the chamfer and the positioning bar can automatically support the hook part along the Y-axis direction, thereby ensuring the size of the hook part along the Y-axis direction and ensuring that the hook part is aligned with the position to be welded of the oil cup body, which effectively improves the work efficiency;

[0019] In addition, since the positioning block is against the bottom wall of the accommodating cavity during the movement of the oil cup, when the alignment and bonding of the position to be welded is completed through the welding tooling, the distance between the hook part and the bottom wall of the accommodating cavity is fixed (always the thickness of the positioning block along the Y-axis direction), thereby improving the dimensional stability of the hook part position after welding is completed.

[0032] For ease of description, in this application, the length direction of the bottom plate 21 is defined as the X-axis direction, the depth direction of the internal accommodating cavity 13 of the oil cup 10 is defined as the Y-axis direction, and the direction perpendicular to both the X-axis and the Y-axis is defined as the Z-axis direction.

[0033] Please combine Figure 1 , Figure 2 as well as Figure 3As shown, the present application first provides an oil cup welding auxiliary structure, including an oil cup 10 and a welding tool 20, the oil cup 10 is slidably arranged on the welding tool 20 along the X-axis direction; the welding tool 20 includes a bottom plate 21, a connecting piece 22 and a positioning block 23, the positioning block 23 is fixed relative to the bottom plate 21 by the connecting piece 22, so as to form a gap between the positioning block 23 and the bottom plate 21; the oil cup 10 includes an oil cup body 11 and a hook portion 12 formed by bending, the oil cup body 11 is provided with a receiving cavity 13, one of the side walls of the oil cup body 11 is inserted into the gap, so that the positioning block 23 is located inside the receiving cavity 13 and abuts against the bottom wall of the receiving cavity 13; a positioning bar 231 extending along the X-axis direction is fixed on the positioning block 23, and one end of the positioning bar 231 close to the hook portion 12 along the X-axis direction has a chamfer 231a, when the positioning bar 231 abuts against the hook portion 12 along the Y-axis direction, the hook portion 12 and the oil cup body 11 are at a position to be welded ( Figure 4 The bold dashed line part in the middle is directly opposite.

[0034] In the present application, by setting the welding fixture 20, the operator only needs to slide the oil cup 10 relative to the bottom plate 21 along the X-axis direction to make the chamfer 231a on the positioning block 23 contact the hook part 12, and as the oil cup 10 moves further, the chamfer 231a and the positioning bar 231 can automatically support the hook part 12 along the Y-axis direction, thereby ensuring the size of the hook part 12 along the Y-axis direction, ensuring that the hook part 12 is aligned with the position to be welded with the oil cup body 11, and effectively improving the work efficiency;

[0035] In addition, since the positioning block 23 is against the bottom wall of the accommodating cavity 13 during the movement of the oil cup 10, when the alignment and bonding of the position to be welded is completed by the welding tool 20, the distance between the hook portion 12 and the bottom wall of the accommodating cavity 13 is fixed (always the thickness of the positioning block 23 along the Y-axis direction), thereby improving the dimensional stability of the position of the hook portion 12 after welding is completed.

[0036] In some embodiments, the positioning block 23 has multiple installation positions, and the positioning strip 231 can be removably fixed to any installation position; so that the positioning strip 231 can be installed to the corresponding installation position according to the size of the oil cup 10, so as to meet the requirements of automatic fitting of the welding positions of oil cups 10 of different sizes and models, thereby improving the versatility of the oil cup welding auxiliary structure of the present application.

[0037] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the connecting member 22 includes a column 221 and a connecting plate 222, one end of the column 221 along the Z-axis direction is fixed to the base plate 21, the connecting plate 222 is fixed to the column 221, and the positioning block 23 is fixed to the end of the connecting plate 222 along the X-axis direction.

[0038] The positioning block 23 is fixedly arranged at the end of the connecting plate 222 along the X-axis direction, so that the column 221 can avoid the hook part 12 along the X-axis direction, thereby avoiding collision and interference between the column 221 and the hook part 12 .

[0039] Specifically, the column 221 is L-shaped, with one end fixed to the base plate 21 and the other end fixed to the connecting plate 222 . When a side wall of the oil cup 10 is inserted into the gap between the positioning block 23 and the base plate 21 , the connecting plate 222 and the positioning block 23 are both located in the accommodating cavity 13 .

[0040] Please refer to Figure 1 As shown, in some embodiments, the connecting plate 222 can be detachably fixed to the column 221, and the positioning block 23 can be detachably fixed to the connecting plate 222; so that different connecting plates 222 or positioning blocks 23 can be selected according to different requirements such as the size and model of the oil cup 10, thereby further improving the versatility of the oil cup welding auxiliary structure of the present application.

[0041] Specifically, the connecting plate 222 and the column 221, and the positioning block 23 and the connecting plate 222 are fixed by bolts. Of course, you can also choose to clamp or other commonly used fixing methods, as long as they can be assembled and unassembled as needed, and this application will not give examples one by one here.

[0042] Please refer to Figure 1 As shown, in some embodiments, a positioning block 23 is fixed to each end of the connecting plate 222 along the X-axis direction; when the hook portion 12 on one side is welded, the oil cup 10 is moved in the opposite direction to complete the removal of the part and the support of the hook portion 12 on the other side, and then the welding on the other side can be completed, thereby further improving the welding efficiency.

[0043] Please refer to Figure 4 As shown, in some embodiments, a plurality of positioning strips 231 are fixedly provided on the positioning block 23; the plurality of positioning strips 231 can evenly support the hook portion 12, so that the height dimension of the hook portion 12 in the Y-axis direction at each position on the XOZ plane can be guaranteed, thereby ensuring product quality.

[0044] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, when the positioning bar 231 and the hook portion 12 are against each other along the Y-axis direction, at least one positioning bar 231 is directly opposite to the position of the hook portion 12 to be welded along the Y-axis direction; the position of the hook portion 12 to be welded has the highest requirement on the accuracy of the height dimension in the Y-axis direction. Setting the positioning bar 231 at this position can improve the dimensional accuracy of the hook portion 12 after welding is completed.

[0045] Please combine Figure 4 as well as Figure 5As shown, in some embodiments, at least one positioning strip 231 extends along the X-axis direction to one end of the positioning block 23 close to the hook portion 12, ensuring that when the hook portion 12 contacts the positioning block 23, it can contact the positioning strip 231 at the first time, so as to deflect along the Y-axis direction under the guidance of the chamfer 231a and complete the alignment and fit with the oil cup body 11, thereby preventing the hook portion 12 from colliding and interfering with the positioning block 23.

[0046] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the positioning bar 231 includes a Y-direction limiting portion 231b and an X-direction limiting portion 231c, and the chamfer 231a is located at the Y-direction limiting portion 231b. When the X-direction limiting portion 231c and the hook portion 12 are against each other along the X-axis direction, the Y-direction limiting portion 231b and the hook portion 12 are against each other along the Y-axis direction.

[0047] When the X-axis limit portion 231c abuts against the hook portion 12, it indicates that the alignment and fit between the hook portion 12 and the oil cup body 11 has been completed; by setting the limit portion 231, the operator does not need to control the moving distance of the oil cup 10, but only needs to move the oil cup 10 until the hook portion 12 abuts against the X-axis limit portion 231c, thereby further reducing the difficulty of the welding operation.

[0048] In some embodiments, the projection of the positioning bar 231 along the Z-axis direction is U-shaped (not shown), wherein the bottom of the U-shape is the X-direction limit portion 231c, the opening of the U-shape faces the hook portion 12, and one side of the Y-direction limit portion 231b is fixed to the positioning block 23; in this arrangement, when the hook portion 12 is offset in the positive or reverse direction along the Y-axis, the positioning bar 231 can guide the hook portion 12 to the correct position.

[0049] A second aspect of the present application provides an oil cup production device, comprising the above-mentioned oil cup welding auxiliary structure.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
