Description

Technical Field

[0001] The utility model belongs to the field of coil winding, and particularly relates to a welding positioning device for a foil coil lead row. Background Art

[0002] The welding positioning device for the transformer coil lead row is an important part of the foil coil winding machine. Usually, at the beginning or end of coil winding, a section of lead row needs to be welded to the foil tape to be integrated for connecting the low-voltage current of the transformer shell. When welding the lead row, the edge of the lead row needs to be aligned and pressed against the edge of the foil tape, and then welded by argon arc welding while moving. However, in the traditional method, there is no available position reference when placing the lead row, and the lead row is often easily placed obliquely, which requires spending time to repeatedly adjust the posture, greatly affecting the welding efficiency. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a welding positioning device for a foil coil lead row to overcome the above technical defects.

[0004] To solve the above technical problems, the utility model provides a welding positioning device for a foil coil lead row, suitable for a lead row, including:

[0005] A frame;

[0006] A loading platform, suitable for placing and moving the lead row, and the loading platform is installed on the frame;

[0007] A pressing plate mechanism, installed on the frame, and the pressing plate mechanism can press down the lead row so that the lead row is positioned between the pressing plate mechanism and the loading platform.

[0008] According to a welding positioning device for a foil coil lead row, the loading platform includes:

[0009] A welding row bottom plate, which has at least two opposite sides, namely a first side and a second side. Among them, the first side is fixed to the frame, and the second side and the remaining plate body are suspended;

[0010] A positioning plate, serving as a positioning reference for the lead row, and the positioning plate is slidably arranged on the welding row bottom plate;

[0011] A lower jaw plate, detachably fixed to the second side of the welding row bottom plate. The lower jaw plate and the welding row bottom plate are suitable for placing the lead row, and the lead row is closely attached to the positioning plate so that the positioning plate in a sliding state can floatingly adjust the position of the lead row.

[0012] According to a welding positioning device for a foil coil lead row, the loading platform further includes:

[0013] The first bracket is in a U-shaped structure. A screw knob is installed on the horizontal rod of the U-shape. The screw of the screw knob presses against the solder row bottom plate after passing through the horizontal rod to lock or loosen the solder row bottom plate.

[0014] Through-hole grooves. Two of the through-hole grooves are spaced apart and opened on the solder row bottom plate. The two U-shaped ends of the first bracket are detachably fixed to the positioning plate after passing through the two through-hole grooves respectively.

[0015] According to a welding positioning device for a foil coil lead row, the pressing plate mechanism includes:

[0016] A cross beam is installed on the machine frame and is located above the loading table. A plurality of cylinders are installed on the beam section of the cross beam. A pressing plate is installed at the telescopic end of each cylinder.

[0017] An upper jaw plate. The upper jaw plate is detachably fixed to the side of each pressing plate. When the cylinder acts, the pressing plate drives the upper jaw plate to tilt so that the upper jaw plate presses the lead row.

[0018] According to a welding positioning device for a foil coil lead row, the contact part between the upper jaw plate and the lead row is in line contact or surface contact.

[0019] The lower jaw plate is composed of a plurality of sub-jaw plates assembled together.

[0020] According to a welding positioning device for a foil coil lead row, the machine frame includes:

[0021] A connecting seat;

[0022] A buckle plate. The buckle plate and the connecting seat are distributed at intervals. The pressing plate mechanism and the loading table are installed between the buckle plate and the connecting seat. Among them, the buckle plate can be opened through a handle so that the foil strip can pass through between the pressing plate mechanism and the loading table and then be laid on the lead row.

[0023] When welding the lead row and the foil strip, it is only necessary to tightly attach the inner edge of the lead row to the positioning plate in the welding positioning device for the foil coil lead row provided by the present invention. When it is necessary to adjust the front and rear positions (along the width direction) of the lead row, loosen the screw knob, and the positioning plate can guide the lead row to move back and forth to quickly reach the target position, avoiding the problem that the lead row is placed crooked due to the lack of a position reference.

These embodiments are provided to disclose the present invention in detail and completely, and to fully convey the scope of the present invention to those skilled in the art. The terms in the exemplary implementation manners shown in the drawings are not limitations on the present invention. In the drawings, the same unit / element uses the same reference numeral.

[0039] Unless otherwise specified, the terms used herein (including technical terms) have the ordinary meaning understood by those skilled in the relevant technical field. Additionally, it can be understood that terms defined in commonly used dictionaries should be construed to have a meaning consistent with their context in the relevant field, and should not be construed as having an idealized or overly formal meaning.

[0040] Please refer to Figure 1 , this embodiment relates to a welding positioning device for a foil coil lead row, suitable for the lead row 40, including a frame 10, a loading platform 20, and a pressing plate mechanism 30. Among them, the pressing plate mechanism 30 and the loading platform 20 are arranged up and down, and both are installed on the frame 10.

[0041] The loading platform 20 is suitable for placing and moving the lead row 40, and reference can be made to Figure 4 .

[0042] The pressing plate mechanism 30 can press down the lead row 40 so that the lead row 40 is positioned between the pressing plate mechanism 30 and the loading platform 20. Among them, the loading platform 20 can not only place the lead row 40, but also provide a reference for the movement of the lead row 40; after the position of the lead row 40 is determined, the pressing plate mechanism 30 can press the lead row 40 tightly to prevent the lead row 40 from shifting during the welding process and affecting the welding result.

[0043] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 , the loading platform 20 includes a welding row bottom plate 21, a positioning plate 22, and a lower jaw plate 23.

[0044] Specifically, the welding row bottom plate 21 has at least two opposite sides, namely the first side and the second side. Among them, the first side is fixed to the frame 10, and the second side and the rest of the plate body are suspended.

[0045] As a positioning reference for the lead row 40, the positioning plate 22 is slidably arranged on the welding row bottom plate 21. In some embodiments, sliders are installed on the bottom surface of the positioning plate 22, and linear guides are installed on the welding row bottom plate 21. That is, the positioning plate 22 slides on the welding row bottom plate 21 through the cooperation of the sliders and the linear guides.

[0046] In some embodiments, the positioning plate 22 is Figure 1 or Figure 3 the strip-shaped plate shown, this strip-shaped plate has two long sides, and one of the long sides is used to closely adhere to the inner edge of the lead row 40. This long side can have a rectangular cross-section or can have an arc chamfer as shown in Figure 1 .

[0047] Please refer to Figure 4, the lower jaw plate 23 is detachably fixed to the second side of the solder strip base plate 21. The lower jaw plate 23 and the solder strip base plate 21 are adapted to place the lead strip 40. The lead strip 40 is closely attached to the positioning plate 22, so that the positioning plate 22 in a sliding state can float and adjust the position of the lead strip 40.

[0048] In this embodiment, the width direction of the positioning plate 22 is defined as the x-direction, that is Figure 5 the left-right direction in []. Then, under the action of the slider, the positioning plate 22 can achieve displacement along the x-direction. As the positioning reference of the lead strip 40, when the lead strip 40 is closely attached to the positioning plate 22, the positioning plate 22 will move or slide and float along the x-direction, thereby realizing the attitude adjustment of the lead strip 40 along the x-direction and ensuring that the lead strip 40 is parallel to the positioning plate 22.

[0049] In some embodiments, the lower jaw plate 23 can be removed, and the second side of the solder strip base plate 21 extends along the x-direction to form an extension plate to replace the lower jaw plate 23. At this time, the lead strip 40 can be placed on this extension plate. That is, the solder strip base plate 21 and the lower jaw plate 23 can be integrated or separated.

[0050] In some embodiments, such as Figure 4 shown, the lower jaw plate 23 is assembled by a plurality of sub-jaw plates. The purpose is to facilitate the replacement and maintenance of the lower jaw plate 23, and to be applicable to the positioning use of lead strips 40 of various specifications.

[0051] Please refer to Figure 2 , the carrier table 20 further includes a first bracket 24. The first bracket 24 has a U-shaped structure. A screw knob 25 is installed on the horizontal rod of the U-shape. The screw of the screw knob 25 abuts against the solder strip base plate 21 after passing through the horizontal rod to lock or loosen the solder strip base plate 21.

[0052] The carrier table 20 further includes through holes. The number of through holes is two. The two through holes are spaced apart on the solder strip base plate 21. The two U-shaped ends of the first bracket 24 are detachably fixed to the positioning plate 22 after passing through the two through holes respectively.

[0053] By screwing the screw knob 25, the tightening degree of the screw knob 25 against the solder strip base plate 21 can be adjusted.

[0054] When the lead strip 40 is placed closely attached to the positioning plate 22 and the position of the lead strip 40 is confirmed, at this time, screw the screw knob 25. The screw knob 25 abuts against the solder strip base plate 21 upward. While realizing the positioning function of the positioning plate 22, an upward acting force is also applied, and the pressing plate mechanism 30 applies a downward pressure, so that the lead strip 40 is clamped.

[0055] In some embodiments, please combine Figure 3 and Figure 4, the pressing plate mechanism 30 includes a cross beam 31 and an upper jaw plate 33. Among them, the cross beam 31 is installed on the frame 10 and is located above the loading platform 20. A plurality of cylinders are installed on the beam section of the cross beam 31, and a pressing plate 32 is installed at the telescopic end of each cylinder. An upper jaw plate 33 is detachably fixed to the side of each pressing plate 32, so that when the cylinder acts, the pressing plate 32 drives the upper jaw plate 33 to tilt, and the upper jaw plate 33 presses the lead row 40.

[0056] When the cylinder expands and contracts, it will drive the pressing plate 32 from Figure 4 state to Figure 5 state, that is, the pressing plate 32 rotates and tilts. Specifically, the pressing plate 32 tilts towards the lead row 40 until the upper jaw plate 33 at the front end of the pressing plate 32 contacts and presses the lead row 40. At this point, the lead row 40 is clamped between the upper jaw plate 33 and the lower jaw plate 23.

[0057] In practical applications, please refer to Figure 5 , a foil tape 50 is also laid on the lead row 40, and the foil tape 50 and the lead row 40 are simultaneously clamped between the upper jaw plate 33 and the lower jaw plate 23. Specifically, it means that the part to be welded is clamped between the upper jaw plate 33 and the lower jaw plate 23. For example, Figure 5 the foil tapes 50 and the lead row 40 on the left and right sides are the welding joints.

[0058] In some embodiments, the cylinder can be replaced by an oil cylinder, an electric cylinder, etc.

[0059] In some embodiments, the contact part between the upper jaw plate 33 and the lead row 40 is in line contact or surface contact. The purpose is to increase the contact area and thus ensure the accuracy of positioning and clamping. Therefore, the structure of the upper jaw plate 33 is preferably Figure 5 shown, similar to a hook shape.

[0060] In some embodiments, please refer to Figure 3 , the frame 10 includes a connecting seat 11 and a buckle plate 12. The buckle plate 12 and the connecting seat 11 are distributed at intervals, or are distributed left and right as shown in Figure 3 . The pressing plate mechanism 30 and the loading platform 20 are installed between the buckle plate 12 and the connecting seat 11. Among them, the buckle plate 12 can be opened through a handle so that the foil tape 50 passes through between the pressing plate mechanism 30 and the loading platform 20 and is laid on the lead row 40.

[0061] Specifically, the buckle plate 12 is a structure that can be opened and closed with a handle and a locking tongue. The structure of the buckle plate 12 when it is closed can be referred to Figure 1 , Figure 2 and Figure 4 , and the structure of the buckle plate 12 when it is opened can be referred to Figure 3When the buckle plate 12 is opened, the foil tape 50 can be taken and passed through between the pressing plate mechanism 30 and the stage 20, and then the foil tape 50 is laid on the lead row 40. As Figure 5 shown, after adjusting the postures of the two and ensuring clamping, welding can be carried out.

[0062] Those of ordinary skill in the art can understand that the above embodiments are specific examples for implementing the present utility model, and in actual applications, various changes can be made in form and details without departing from the spirit and scope of the present utility model.
