Description

Technical Field

[0001] The present invention relates to the technical field of transformer manufacturing, and in particular to a transformer coil stay pressing device and a transformer coil stay notch processing device. Background Art

[0002] Transformer coils are an important component of transformers, and transformer coil stays are key components in their manufacture. The outer diameter side of the stays is divided into multiple sections with electrical shrink tape binding slots. To achieve this, a woodworking saw is typically used for slotting the outer diameter side of the stays. However, during the slotting process, the operator must manually support the stays and then use the saw to slot. This slotting method is limited by the number of stays that the operator can manually support at one time (a maximum of 2-3 stays can be milled side by side at a time), so multiple milling operations are required. This method is not only inefficient, but also prone to misalignment of the stays during processing, resulting in substandard slotting quality. Furthermore, there is a safety hazard associated with manually supporting the stays, which can easily injure the operator with the saw blade. Summary of the Invention

[0020] In one embodiment of the present application, the clamping drive mechanism is used to drive the clamping member to move between the clamping position, the limit position and the release position, and the limit position is located between the clamping position and the release position. When the clamping member is in the limit position, the transformer coil support bar can and can only move along the first direction and the second direction.

[0021] In one embodiment of the present application, the limiting device includes a first limiting member, a second limiting member and a position adjustment mechanism, the opposite surfaces of the first limiting member and the second limiting member are the first limiting surfaces, at least one of the first limiting member and the second limiting member is transmission-connected to the position adjustment mechanism, and the position adjustment mechanism is used to adjust the distance between the first limiting member and the second limiting member along the first direction.

DETAILED DESCRIPTION

[0033] One of the core points of the present invention is to provide a transformer coil support bar clamping device. The structural design of the transformer coil support bar clamping device enables it to quickly and stably clamp and fix multiple support bars, meet the notch processing requirements, improve the notch processing quality and efficiency, and reduce safety hazards during the processing process.

[0034] Another core of the present invention is to provide a transformer coil stay notch processing device including the above-mentioned transformer coil stay pressing device.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The transformer coil is used to form the internal circuit of the transformer and is directly connected to the external power grid. It is the most important component of the transformer. The transformer coil support is an important component when assembling the transformer coils. It not only provides transformer oil circulation space between the coils, but also ensures the insulation distance.

[0037] In actual use, the transformer coil support bar needs to be provided with a plurality of slots spaced apart along the length direction of the support bar, so that the protruding end of the transformer coil can be tied to the slots of the transformer coil support bar by binding ropes for fixation.

[0038] At present, the notch processing of transformer coil struts is generally carried out by a woodworking milling saw. The processing personnel are required to manually support and fix 2 to 3 transformer coil struts to be processed, locate the slotting position, and then use the woodworking milling saw to uniformly notch the above-mentioned transformer coil struts to be processed. After one notch processing is completed, the position of each transformer coil strut to be processed is readjusted, and the next notch position is located before processing. This process is repeated until all notches are processed.

[0039] It is foreseeable that in the above-mentioned notch processing process, the processing personnel support the transformer coil support bar to be processed with one hand and operate the woodworking milling saw with the other hand. Therefore, the number of transformer coil support bars to be processed that can be fixed at one time is limited, and the efficiency is low. In addition, in the process of adjusting the position of each transformer coil support bar to be processed after one processing, each transformer coil support bar to be processed is easily misaligned and needs to be adjusted repeatedly to align them, which further reduces the processing efficiency and easily affects the notch processing quality and consistency. There is also a safety hazard of the saw blade of the woodworking milling saw injuring people. For this reason, the embodiment of the present application provides a transformer coil support clamping device, please refer to Figure 1 .

[0040] The transformer coil stay pressing device includes a supporting device 100 , a limiting device and a pressing device 300 .

[0041] The top of the support device 100 has a support plane 100a, which can be a horizontal plane or an inclined plane. Of course, the top of the support device 100 can also adopt an inclination-adjustable structure to make the inclination of the support plane 100a adjustable.

[0042] The support plane 100a is used to place multiple transformer coil struts 400 arranged along the first direction and extending along the second direction. Therefore, the size of the support plane 100a along the first direction should be greater than the sum of the sizes of a preset number of transformer coil struts 400 to be processed along the first direction. The size of the support plane 100a along the second direction can be greater than, equal to, or less than the size of the transformer coil struts 400 along the second direction, that is, the projection of the transformer coil strut 400 on the support plane 100a can be completely located within the range of the support plane 100a, or can be partially located within the range of the support plane 100a, and the rest is located outside the range of the support plane 100a. The support plane 100a can be a circular surface, a rectangular surface, etc., which is not limited here.

[0043] like Figure 1 As shown, in one embodiment of the present application, the support device 100 includes a support frame 110 and a support platform 120 . The support platform 120 is arranged on the top of the support frame 110 , and the support plane 100 a is a side surface of the support platform 120 away from the support frame 110 .

[0044] Please continue reading Figure 1 In this case, the support platform 120 is a rectangular platform, and the support frame 110 is composed of 4 columns and 4 beams. The 4 columns are respectively arranged at the four corners of the bottom of the support platform 120, and the adjacent two columns in the circumferential direction are connected by beams to improve the stability of the support frame 110.

[0045] The limiting device is arranged on the supporting plane 100a. The limiting device can be fixed to the supporting plane 100a or fixed to the supporting plane 100a in an adjustable position. The limiting device has a first limiting surface 200a perpendicular to the first direction and / or a second limiting surface perpendicular to the second direction. The first limiting surface 200a is used to limit each transformer coil support 400 at one end in the arrangement direction of each transformer coil support 400, that is, the first limiting surface 200a only contacts and cooperates with the edge of a transformer coil support 400 located at the edgemost in a row of transformer coil supports 400. The second limiting surface is used to limit each transformer coil support 400 at one end in the extension direction of each transformer coil support 400, that is, the second limiting surface contacts and cooperates with the end of each transformer coil support 400 in a row of transformer coil supports 400.

[0046] The limiting device may have only a first limiting surface 200a. When the limiting device has only one first limiting surface 200a, it can limit each transformer coil support bar 400 on one side of the first direction. When the limiting device has two oppositely arranged first limiting surfaces 200a, it can limit the transformer coil support bar 400 on both sides of the first direction.

[0047] The limiting device may also have only a second limiting surface. When the limiting device has only one second limiting surface, it can limit each transformer coil support bar 400 on one side of the second direction. When the limiting device has two oppositely arranged second limiting surfaces, it can limit the transformer coil support bar 400 on both sides of the second direction.

[0048] Of course, the limiting device may also have a first limiting surface 200a and a second limiting surface, so that the transformer coil stay 400 can be limited in both the first direction and the second direction.

[0049] The clamping device 300 is arranged on the supporting device 100. The clamping device 300 includes a clamping drive mechanism and a clamping member 320. The clamping drive mechanism is used to drive the clamping member 320 to move between a clamping position and a release position. The release position is usually located above the clamping position. When the clamping member 320 is in the clamping position, it can press multiple transformer coil struts 400 to the supporting plane 100a, that is, when the clamping member 320 is in the clamping position, the transformer coil struts 400 cannot move in the first direction and the second direction.

[0050] One or more clamping devices 300 can be set. If the length of the transformer coil support bar 400 (the dimension in the second direction) is long, multiple clamping devices 300 can be set at intervals along the second direction to prevent the transformer coil support bar 400 from being lifted up when one end is clamped.

[0051] The clamping drive mechanism can adopt a variety of structures. For example, the clamping drive mechanism can be a piston cylinder, such as the air cylinder 310 and the hydraulic cylinder, and the movement of the clamping member 320 between the clamping position and the release position is achieved by the extension and contraction of the piston rod. The clamping drive mechanism can also be a linear motor, and the movement of the clamping member 320 between the clamping position and the release position is achieved by the linear reciprocating movement of the linear motor. The clamping drive mechanism can also be a rotary motor and a transmission mechanism. The transmission mechanism is used to convert the rotation of the rotary motor into linear reciprocating movement. The transmission mechanism includes but is not limited to a screw slider mechanism and a gear rack mechanism.

[0052] Of course, it should be noted that the pressing drive mechanism can also adopt a manual pressing mechanism.

[0053] The pressing member 320 can be in various structures such as plate, strip, column, etc. Figure 1 In the illustrated embodiment, in order to increase the contact area between the pressing member 320 and the transformer coil stay 400 , the pressing member 320 adopts a plate-shaped structure.

[0054] During application, multiple transformer coil struts 400 are placed on the supporting plane 100a of the supporting device 100. The number of transformer coil struts 400 is related to the size of the clamping member 320 along the first direction, that is, the larger the size of the clamping member 320 along the first direction, the more transformer coil struts 400 it can clamp at the same time. Therefore, according to processing requirements, the size of the clamping member 320 along the first direction can be adjusted, and each transformer coil strut 400 is limited by a limiting device so that they are tightly arranged and aligned at both ends. Then, the clamping drive mechanism of the clamping device 300 drives the clamping member 320 to press down, and each transformer coil strut 400 is clamped and fixed for subsequent notch processing.

[0055] Compared with the prior art, the transformer coil support bar clamping device provided in the embodiment of the present application can replace the processing personnel to clamp the transformer coil support bar 400, eliminating the safety hazard of saw blades injuring people caused by milling devices such as pull milling saws used by carpenters, and the size of the clamping member 320 of the transformer coil support bar clamping device along the first direction can be designed according to needs, so that all transformer coil supports 400 to be processed can be clamped at one time, thereby improving the notch processing efficiency, and the limiting device facilitates the positioning of the transformer coil support bar 400 when adjusting its position, avoiding misalignment of each transformer coil support bar 400 during the movement from the previous notch processing position to the next notch processing position, thereby improving the consistency and processing quality of the notch processing of each transformer coil support bar 400.

[0056] like Figure 1As shown, in one embodiment of the present application, in order to facilitate the installation and fixation of the clamping drive mechanism, the clamping device 300 also includes a mounting bracket 340 for fixing the clamping drive mechanism, and the mounting bracket 340 is arranged on the support device 100. It should be noted that the mounting bracket 340 can be fixedly arranged on the support device 100, that is, the mounting bracket 340 is immovably arranged on the support device 100, or it can be adjustably arranged on the support device 100. Adjustable position means that the mounting bracket 340 can be adjustable in position along the first direction and / or the second direction, and the clamping drive mechanism is adjustably arranged on the mounting bracket 340 along the third direction. This makes it more convenient to adjust the distance between the clamping member 320 and the support plane 100a when it is in the clamping position, and the third direction intersects with the support plane 100a.

[0057] Specifically, the clamping drive mechanism can be installed on the mounting bracket 340 through a first threaded fastener. Accordingly, the mounting bracket 340 is provided with a plurality of first mounting holes spaced along a third direction, and a second mounting hole is provided on the clamping drive mechanism. The first threaded fastener cooperates with the first mounting hole and the second mounting hole respectively to fix the clamping drive mechanism to the mounting bracket 340. When the position of the clamping drive mechanism needs to be adjusted, the first threaded fastener can be removed and the cooperating first mounting hole can be replaced to adjust the position of the clamping drive mechanism.

[0058] To facilitate notch processing, in one embodiment of the present application, the mounting bracket 340 is adjustably arranged on the support device 100 along the first direction, so that the clamping position can be adjusted to cooperate with a milling device such as a woodworking saw, making notch processing more convenient.

[0059] like Figure 1 As shown, in a specific embodiment, the mounting bracket 340 includes an L-shaped base 341, a transverse support beam 342 and a vertical mounting beam 343, wherein the transverse portion of the L-shaped base 341 is arranged on the supporting plane 100a parallel to the supporting plane 100a, the vertical portion of the L-shaped base 341 extends in a direction away from the supporting plane 100a, the first ends of multiple transverse support beams 342 are connected to the vertical portion of the L-shaped base 341 at intervals along the extension direction of the vertical portion of the L-shaped base 341, the second ends of each transverse support beam 342 are respectively connected to the vertical mounting beam 343, and the clamping drive mechanism is arranged on the vertical mounting beam 343.

[0060] The transverse portion of the L-shaped base 341 and the transverse support beam 342 may extend in the same direction or in opposite directions. Figure 1 In the illustrated embodiment, the transverse portion of the L-shaped base 341 extends in opposite directions from the transverse support beam 342 . Two transverse support beams 342 are provided and are connected to both ends of the vertical mounting beam 343 , respectively.

[0061] The mounting bracket 340 of the above structure is not easily deformed, which can ensure the stability and pressing effect of the pressing drive mechanism during the pressing process.

[0062] To further optimize the above technical solution, reinforcing ribs may be provided between the horizontal portion and the vertical portion of the L-shaped base 341 to further increase the stability of the mounting bracket 340 .

[0063] exist Figure 1 In the illustrated embodiment, the mounting bracket 340 can be fixed to the supporting plane 100a by a second threaded fastener, that is, a third mounting hole is opened on the supporting plane 100a, and a fourth mounting hole is opened on the transverse portion of the L-shaped base 341 of the mounting bracket 340. The second threaded fastener cooperates with the third mounting hole and the fourth mounting hole respectively to fix the mounting bracket 340 to the supporting plane 100a.

[0064] A plurality of third mounting holes may be spaced apart along the first direction on the support plane 100a. When the second threaded fastener passes through the fourth mounting hole and cooperates with different third mounting holes, the position of the mounting bracket 340 may be adjusted along the first direction.

[0065] Of course, a slide groove can also be provided on one of the support plane 100a and the transverse part of the L-shaped base 341 of the mounting bracket 340, and a slide platform can be provided on the other. The slide platform is embedded in the slide groove and slidably cooperates with the slide groove to realize position adjustment of the mounting bracket 340 along the first direction. Specifically, a slide groove extending along the first direction can be opened on the support plane 100a, and a plurality of third mounting holes can be provided at the bottom of the slide groove or the bottom of the slide groove can be hollowed out to form a long strip of third mounting holes, and a slide platform can be provided at the bottom of the transverse part of the L-shaped base 341 of the mounting bracket 340, and the fourth mounting hole passes through the transverse part of the L-shaped base 341 and the slide platform. When the second threaded fastener is removed, the mounting bracket 340 can slide along the slide groove. When the second threaded fastener cooperates with the third mounting hole and the fourth mounting hole, the mounting bracket 340 can be locked and fixed relative to the support plane 100a.

[0066] See also Figure 1 In order to prevent the surface of the transformer coil stay 400 from being damaged during the pressing process, in one embodiment of the present application, the pressing member 320 includes a pressing plate 321 and a buffer pad 322. The pressing plate 321 is arranged at the driving end of the pressing drive mechanism, and the pressing plate 321 is parallel to the supporting plane 100a. The buffer pad 322 is arranged on the plate surface of the pressing plate 321 facing the supporting plane 100a. The buffer pad 322 can be a silicone pad, a rubber pad, an epoxy resin pad, etc., that is, during the pressing process, the buffer pad 322 can undergo a certain degree of elastic deformation to avoid direct hard contact between the pressing plate 321 and the transformer coil stay 400.

[0067] Please continue reading Figure 1 In one embodiment, the pressing drive mechanism includes a cylinder 310 and a foot switch 330. The air inlet and outlet of the cylinder 310 are connected to the air distribution port of the foot switch 330 via an air pipe, and the air inlet of the foot switch 330 is connected to the air source. During notch processing, the cylinder 310 can be controlled by stepping on the foot switch 330. Of course, the cylinder 310 can be stopped in the pressing position and the release position by adding a solenoid valve in the air circuit, and the stop position of the cylinder 310 can be controlled by different operating modes of the foot switch 330, for example, by using a double-point foot switch 330 or by long-stepping on the foot switch 330 to control the stop position of the cylinder 310.

[0068] To further optimize the above technical solution, in order to improve the degree of automation when the transformer coil support bar 400 is compressed and reduce the workload of the processing personnel, in a specific embodiment of the present application, the compression drive mechanism is used to drive the compression member 320 to move between the compression position, the limit position and the release position. The limit position is located between the compression position and the release position. When the compression member 320 is in the limit position, the transformer coil support bar 400 can and can only move along the first direction and the second direction, that is, in this limit position, each transformer coil support bar 400 can and can only move parallel to the support plane 100a, and cannot move in a direction away from the support plane 100a, so as to avoid relative stacking when subjected to external force.

[0069] Correspondingly, the limiting device includes a first limiting member 200, a second limiting member and a position adjustment mechanism. The opposite surfaces of the first limiting member 200 and the second limiting member are the first limiting surface 200a. At least one of the first limiting member 200 and the second limiting member is transmission-connected to the position adjustment mechanism. The position adjustment mechanism is used to adjust the distance between the first limiting member 200 and the second limiting member along the first direction.

[0070] Before the notch processing begins, multiple transformer coil struts 400 are placed side by side between the first limit member 200 and the second limit member. The clamping drive mechanism drives the clamping member 320 to the limit position, and then the position adjustment mechanism starts the first limit member 200 and the second limit member to approach each other until the transformer coil struts 400 are closely arranged. At this time, the ends of the transformer coil struts 400 are aligned, and the clamping drive mechanism can drive the clamping member 320 to move to the clamping position to clamp the transformer coil struts 400.

[0071] Furthermore, the limiting device also includes a third limiting member and a fixed-length pushing mechanism. The third limiting member is provided with a second limiting surface. The fixed-length pushing mechanism is transmission-connected to the third limiting member. The fixed-length pushing mechanism pushes the third limiting member to move a preset distance in the second direction each time. The preset distance is the distance between two adjacent notches. When one notch is processed, the clamping drive mechanism drives the clamping member 320 to the limiting position. After the fixed-length pushing mechanism pushes the third limiting member to move the preset distance in the second direction, the clamping drive mechanism drives the clamping member 320 to clamp again, thereby processing the next notch. The fixed-length pushing mechanism can be implemented using a fixed-length servo motor.

[0072] Of course, in order to realize the automation of the processing of the transformer coil support bar 400, a controller is also required.
