Description

Technical Field

[0001] The utility model relates to a transformer, in particular to processing equipment for silicon steel sheets constituting the transformer iron core. Background Art

[0002] The transformer core is made of several stacked silicon steel sheets. The thickness of these stacked sheets needs to be measured. Conventionally, workers use a ruler to measure the stacked sheets on a workbench. This is not only cumbersome, but also results in uncertain accuracy.

[0003] The patent document with authorization announcement number CN219200286U discloses an iron chip measuring mechanism, which includes an outer bracket fixed to a workbench and a bracket assembly surrounded by the outer bracket. A pair of parallel L-shaped frames are hinged on the bracket assembly, and the L-shaped frames are tilted. The L-shaped frames lean against the outer bracket. Each L-shaped frame is provided with a pressing cylinder, and the piston rod of the pressing cylinder is connected to a pressure block. Several silicon steel sheets are stacked and placed on the pair of parallel L-shaped frames. The pressing cylinder drives the pressure block, and the pressure block presses the stacked silicon steel sheets. Because the pair of L-shaped frames are tilted, the silicon steel sheets stacked on the pair of L-shaped frames are tilted. In this way, when the pressure block presses the silicon steel sheets, workers can easily measure the thickness of the silicon steel sheets, which is conducive to the accuracy of the measurement results.

[0004] For smaller silicon steel sheets, the width of a pair of L-shaped frames when put together may exceed the width of the silicon steel sheet. This is not only not conducive to the positioning of the silicon steel sheet, but also difficult to measure it conveniently and accurately. Utility Model Content

[0005] The technical problem solved by the present invention is that for silicon steel sheets of smaller size, the width of a pair of L-shaped frames together may exceed the width of the silicon steel sheet, which is not only not conducive to the positioning of the silicon steel sheet, but also difficult to measure it conveniently and accurately.

[0006] To solve the above technical problems, the utility model provides the following technical solutions: a transformer silicon steel sheet measuring mechanism, comprising an outer bracket fixed on a workbench, a bracket assembly surrounded by the outer bracket, a pair of parallel L-shaped brackets provided on the bracket assembly, each L-shaped bracket provided with a pressing cylinder, the piston rod of the pressing cylinder being connected to a pressure block;

[0007] A pair of L-shaped frames includes a first L-shaped frame and a second L-shaped frame, the frame assembly includes a first frame arranged transversely, the first L-shaped frame is connected to the first frame, the second L-shaped frame is connected to a movable block, the movable block is engaged with the first frame, and the second L-shaped frame can move closer to or away from the first L-shaped frame;

[0008] The first L-shaped frame is provided with an L-shaped positioning structure extending laterally, and the L-shaped positioning structure is equipped with a positioning block; a side push connector extending forward is installed on the first bracket, and the side push connector can move closer to or away from the first L-shaped frame. A side push connector is hingedly connected to the side push connector, and the side push connector is located between a pair of L-shaped frames.

[0009] According to the above technical solution, for larger silicon steel sheets, they are supported by the first L-shaped frame and the second L-shaped frame, while for smaller silicon steel sheets, they can be directly positioned on the L-shaped positioning structure, with the left side of the silicon steel sheet limited by the positioning block, and the right side of the silicon steel sheet limited by the side pusher. When the side pusher is displaced laterally toward the first L-shaped frame, the side pusher in the inclined state acts on the right side of the silicon steel sheet to align the stacked silicon steel sheets up and down. The worker uses a plate to act on the front of the silicon steel sheet and pushes it backward to align the stacked silicon steel sheets up and down. Afterwards, the pressing cylinder of the first L-shaped frame is started, and the pressing block presses the stacked silicon steel sheets up and down. The worker measures the thickness of the stack of silicon steel sheets with a ruler at the front position of the stack of silicon steel sheets, or the worker moves the side pusher away from the silicon steel sheets and measures the thickness of the stack of silicon steel sheets with a ruler at the right position of the stack of silicon steel sheets.

[0010] For smaller silicon steel sheets, the present invention allows them to be positioned directly on the first L-shaped frame for measurement, which is not only convenient but also provides accurate measurement results. For larger silicon steel sheets, which require support from a pair of L-shaped frames, the worker rotates the side pusher backward to move it out of the space between the pair of L-shaped frames.

[0011] The positioning block is equipped with a slot that fits into the bottom horizontal plate of the L-shaped positioning structure. A positioning block fastening bolt is screwed onto the bottom of the positioning block, one end of which can abut against the bottom surface of the bottom horizontal plate of the L-shaped positioning structure. Loosening the positioning block fastening bolt allows the positioning block to move laterally (left and right) along the bottom horizontal plate to adapt to the size of the silicon steel sheet, achieving the purpose of positioning the silicon steel sheet and facilitating its measurement.

[0012] The first bracket includes a transverse plate, to which the side thrust connector is connected via a hook. The hook has a top threaded hole and a back threaded hole, each of which is fitted with a hook fastening bolt that abuts the transverse plate. The hook is hooked onto the transverse plate and secured with two hook fastening bolts. To adjust the transverse position of the side thrust connector, a worker loosens the hook fastening bolt, allowing the hook to move along the transverse plate. Once the hook is properly positioned, the hook fastening bolt is tightened.

[0013] The side pusher is equipped with an arc-shaped limit groove, and the side push connector is equipped with a limit pin, which fits into the arc-shaped limit groove. The limit pin is located next to the hinge axis. When the side pusher is no longer needed, the worker rotates the side pusher backward, and the limit pin moves relative to the arc-shaped limit groove until it reaches its limit position. When the side pusher is needed, the worker rotates the side pusher forward, and the limit pin moves relative to the arc-shaped limit groove until it reaches its limit position.

[0014] The first L-shaped frame is fixedly connected to the first bracket via the first L-shaped frame connector. The first L-shaped frame is hinged on the first L-shaped frame connector. A first inclined backrest is fixed on the first L-shaped frame connector, and the first L-shaped frame can lean backward on the first inclined backrest. The second L-shaped frame is hinged on the movable block. A second inclined backrest is fixed on the movable block, and the second L-shaped frame can lean backward on the second inclined backrest. When stacking silicon steel sheets on the L-shaped frame, the first L-shaped frame and the second L-shaped frame are in an upright state, which is conducive to the neat stacking of the silicon steel sheets up and down. After the stacked silicon steel sheets are pressed with a cylinder, the worker pushes the first L-shaped frame, or the first L-shaped frame and the second L-shaped frame backward, so that the L-shaped frame leans on the corresponding inclined backrest and is in an inclined state. This makes it convenient for workers to measure and read data.

[0015] The bracket assembly includes a second bracket with a vertical guide bar. The first bracket flexibly engages the vertical guide bar. A locking block is fixed to the first bracket, defining a first locking hole. The vertical rod of the second bracket is provided with a row of second locking holes. The first locking hole can be aligned with any of the second locking holes in the row. The first bracket can be raised or lowered relative to the second bracket. When the desired height is reached, a pin is inserted into the corresponding first and second locking holes to lock the height of the first bracket. This height adjustment allows the first bracket to accommodate workers of varying heights.

[0016] The horizontal longitudinal rod of the second bracket is movably matched with the outer bracket through the slider assembly. In this way, the bracket assembly can be displaced forward and backward relative to the outer bracket to facilitate workers to measure the silicon steel sheet.

[0017] The transformer silicon steel sheet measuring mechanism of the utility model can adapt not only to silicon steel sheets with larger sizes, but also to silicon steel sheets with smaller sizes, thus expanding the scope of application. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A pair of L-shaped frames includes a first L-shaped frame 23 and a second L-shaped frame 24. The bracket assembly includes a first bracket 20 arranged horizontally. The first L-shaped frame is connected to the first bracket, and the second L-shaped frame is connected to the movable block 25. The movable block is fitted on the first bracket, and the second L-shaped frame can move closer to or away from the first L-shaped frame.

[0033] The first L-shaped frame is provided with an L-shaped positioning structure 231 extending to the side, and the L-shaped positioning structure is equipped with a positioning block 232; the first bracket is equipped with a side push connector 51 extending forward, and the side push connector can move closer to or away from the first L-shaped frame. The side push connector is hinged with a side push member 50, and the side push member is located between a pair of L-shaped frames.

[0034] The positioning block 232 is provided with a slot 233, which is fitted on the bottom horizontal plate of the L-shaped positioning structure 231. The bottom of the positioning block is screwed with a positioning block fastening bolt, and one end of the positioning block fastening bolt can be against the bottom surface of the bottom horizontal plate of the L-shaped positioning structure.

[0035] The first bracket 20 includes a transverse plate 26, and the side thrust connector 51 is connected to the transverse plate through a hook 52. The hook is provided with a top threaded hole 521 and a back threaded hole 522. The top threaded hole and the back threaded hole are both equipped with hook fastening bolts, and the hook fastening bolts are against the transverse plate.

[0036] like Figure 3 The side push member 50 is provided with an arc-shaped limiting groove 501, and the side push connecting member 51 is provided with a limiting pin 511, which is matched in the arc-shaped limiting groove.

[0037] like Figure 2 The first L-shaped frame 23 is fixedly connected to the first bracket 20 via a first L-shaped frame connector 235. The first L-shaped frame is hinged to the first L-shaped frame connector, which is fixed with a first inclined backrest 236, allowing the first L-shaped frame to lean backward against the first inclined backrest. The second L-shaped frame 24 is hinged to the movable block 25, which is fixed with a second inclined backrest 241, allowing the second L-shaped frame to lean backward against the second inclined backrest.

[0038] The bracket combination includes a second bracket 30, which is provided with a vertical guide bar 31. The first bracket 20 is movably fitted on the vertical guide bar. A locking block 27 is fixed on the first bracket, and the locking block has a first locking hole 271. A row of second locking holes 32 is provided on the vertical rod of the second bracket, and the first locking hole can be aligned with any lock hole in the row of second lock holes.

[0039] The horizontal longitudinal rod of the second bracket 30 is movably engaged with the outer bracket 10 via a slider assembly 33 .

[0040] In actual operation, initially, the first L-shaped frame 23 and the second L-shaped frame 24 are in an upright state. For smaller silicon steel sheets, they can be directly positioned on the L-shaped positioning structure 231. The left side of the silicon steel sheet is limited by the positioning block 232, and the right side of the silicon steel sheet is limited by the side pusher 50. When the side pusher is laterally displaced toward the first L-shaped frame 23, the side pusher in the inclined state acts on the right side of the silicon steel sheet to align the stacked silicon steel sheets up and down. The worker uses a plate to act on the front of the silicon steel sheet and pushes it backward to align the stacked silicon steel sheets up and down. Afterwards, the pressing cylinder 21 of the first L-shaped frame 23 is activated, and the pressing block 22 presses the stacked silicon steel sheets up and down. Afterwards, the worker pushes the first L-shaped frame 23 backward so that the first L-shaped frame rests on the first inclined backrest 236 and is in an inclined state, which is convenient for the worker to measure and read data. The worker measures the thickness of the stack of silicon steel sheets with a ruler at the front of the stack of silicon steel sheets, or the worker moves the side pusher 50 away from the silicon steel sheets and measures the thickness of the stack of silicon steel sheets with a ruler at the right side of the stack of silicon steel sheets.

[0041] For larger silicon steel sheets, workers rotate the side pushers 50 backward, moving them out of the space between the pair of L-shaped frames. The larger silicon steel sheet is then supported by both the first and second L-shaped frames 23 and 24. After the stack of silicon steel sheets is aligned vertically, the compression cylinders 21 of the first and second L-shaped frames 23 and 24 are activated, and the pressure blocks 22 compress the stacked sheets. The worker then pushes the first and second L-shaped frames 23 and 24 backward, positioning them against their corresponding inclined backrests. This tilts the pair of L-shaped frames, making it easier for the worker to measure and read data. The worker then uses a ruler to measure the thickness of the stack of silicon steel sheets at the center of the front edge.
