TECHNICAL FIELD

[0001] The utility model belongs to transformer core manufacturing field, specifically proposes a kind of special equipment for the glue brushing auxiliary and subsequent assembly of three-dimensional winding transformer core. BACKGROUND

[0002] The core plays an important role in the production and manufacturing process of transformer, and the quality of the core directly affects the performance of the final product transformer. After the three-dimensional winding core is annealed, it needs to be brushed with glue, and then assembled after the glue brushing operation is completed.

[0003] Such operation processing quality has an important influence on the performance of finished core, and at present, it is still mainly completed manually by workers on a simple platform. The basic process is as follows: first, place the core on the platform table, brush the surface of the three cores respectively, then control one core by three groups of workers, align, assemble and fix the three cores. In actual operation, when assembling after brushing, the glue surface will be damaged, and the glue needs to be repaired and trimmed after assembly. At the same time, due to the heavy weight of the core and the fact that the three-dimensional winding transformer core is made of amorphous strip material, the edge of the strip material is sharp and easy to scatter during operation and handling, usually requiring multiple people to complete.

[0004] The quality of manual operation brushing glue and the assembly fit and precision of prior art cannot be guaranteed, resulting in low product pass rate, high cost and low efficiency, and there is a great safety hazard. Moreover, the glue liquid will stick to the clothes and even the skin of the workers during operation, which has a great impact on the health of the workers.

[0005] Therefore, it is urgent to explore a glue brushing auxiliary and subsequent assembly device for three-dimensional winding transformer core to solve the above problems. In view of this, the present application is proposed. CONTENT OF THE UTILITY MODEL

[0009] Further, a group of slewing bearings are arranged between the top end of the lifting mechanism and the connecting seat, the inner ring and the outer ring of the slewing bearings are fixedly connected to the connecting seat and the top end of the lifting mechanism respectively, a rotary motor is arranged on one side of the connecting seat or the lifting mechanism, the output end of the rotary motor is connected to a gear, and the gear is in meshing connection with the external teeth of the slewing bearing.

DETAILED DESCRIPTION

[0026] ​The technical solutions proposed in the present application will be clearly and completely described below in combination with the above-described drawings. For those skilled in the art, the described embodiments are only part of the embodiments of the present application but not all the embodiments. Based on the following embodiments, all other embodiments obtained by those skilled in the art without creative labor shall fall within the protection scope of the present application.

[0027] As shown in Embodiment 1, Figure 1 The suspension type three-dimensional core brush gluing and assembling equipment comprises three groups of main bodies 6 which are connected end to end through connecting assemblies 7 and horizontally arranged and distributed at an angle of 120° with respect to each other; each group of main bodies 6 has a vertical fixed stand 1, the top end of the stand 1 is connected to one end of a horizontal moving mechanism 2 arranged in a horizontal direction, and the other end of the horizontal moving mechanism 2 is fixed to the connecting assembly 7; a lifting mechanism 3 is movably connected to the horizontal moving mechanism 2 in a vertical direction, and a clamping jaw mechanism 4 for hanging and clamping the core 5 is drivingly connected to the lifting mechanism 3.

[0028] While the connecting assemblies 7 connect the three groups of main bodies 6 into an integral structure, the stand 1 provides a fixed support for the other structures of the main bodies 6.

[0029] As shown in Embodiment 1, Figure 2 and Figure 2-1 The horizontal moving mechanism 2 has a crossbeam 203, a horizontal moving motor 206 and at least one group of first guide rail assemblies 207 are fixed to the crossbeam 203, the top end of the lifting mechanism 3 is rotatably connected to a connecting seat 204, the connecting seat 204 is slidingly connected to the first guide rail assemblies 207, and the horizontal moving motor 206 is drivingly connected to the connecting seat 204 through a first screw nut assembly 205; under the driving of the horizontal moving motor 206, the first screw nut assembly 205 drives the connecting seat 204 to reciprocatingly translate along the first guide rail assemblies 207, thereby realizing the horizontal movement of the whole lifting mechanism 3.

[0030] Meanwhile, the lifting mechanism 3 is rotatably connected to the connecting seat 204 at its top end, so that it can rotate synchronously with the clamping jaw mechanism 4 and the core 5 clamped thereby, thereby facilitating the workers to hang the core. For this purpose, a group of slewing bearings 201 can be arranged on the shaft between the top end (such as a fixed frame 301) of the lifting mechanism 3 and the connecting seat 204, the inner ring and the outer ring of the slewing bearing 201 are fixedly connected to the connecting seat 204 and the top end (such as the fixed frame 301) of the lifting mechanism 3 respectively, a rotating motor 202 is arranged on one side of the connecting seat 204 or the lifting mechanism 3, the output end of the rotating motor 202 is connected to a gear 208, and the gear 208 is meshingly connected to the outer teeth of the slewing bearing 201; under the driving of the rotating motor 202, the slewing bearing 201 drives the lifting mechanism 3 to reciprocatingly rotate, thereby causing the clamping jaw mechanism 4 and the core 5 clamped thereby to rotate synchronously, which facilitates the workers to hang the core 5 from a more convenient angle, and thereby realizes the synchronous assembling operation of the three groups of cores 5.

[0031] The lifting mechanism 3 has a fixed frame 301 vertically rotatably connected to the horizontal moving mechanism 2 (connecting seat 204), and at least one set of second guide rail assemblies 302 are fixedly connected to the fixed frame 301. A lifting motor 305 is driven to be connected to a lifting frame 303 coaxially sleeved on the fixed frame 301 through a second lead screw nut assembly 304. The clamping jaw mechanism 4 is fixedly connected to the lifting frame 303. Under the driving of the lifting motor 305, the lifting frame 303 and the clamping jaw mechanism 4 are driven by the second lead screw nut assembly 304 to reciprocatingly vertically ascend and descend.

[0032] The clamping jaw mechanism 4 has a fixed seat 401 fixedly connected to the lifting mechanism 3 (lifting frame 303). An upper clamping jaw 402, a clamping cylinder 404 and a third guide rail assembly 405 are fixedly connected to the fixed seat 401 by bolts. The piston rod of the clamping cylinder 404 is drivingly connected to a lower clamping jaw 403, and the lower clamping jaw 403 is slidingly connected to the third guide rail assembly 405. Under the driving of the clamping cylinder 404, the lower clamping jaw 403 moves vertically along the third guide rail assembly 405 and reciprocatingly relative to the upper clamping jaw 402, so as to realize the opening and closing of the two to hang and clamp the iron core 5.

[0033] Based on the above-mentioned suspension type three-dimensional core winding and gluing assembling equipment, the following operation process can be realized:

[0034] After the clamping jaw mechanism 4 is rotated to a suitable position, the iron core 5 is hung on the clamping jaw mechanism 4. The lower clamping jaw 403 is driven by the clamping cylinder 404 to press the inner window of the iron core 5 to prevent it from falling off.

[0035] The lifting mechanism 3 is connected to the connecting seat 204 through the rotary support 201, and the rotary motion of the lifting mechanism 3 is realized by driving the rotary motor 202, so that the clamping jaw mechanism 4 fixed to the lifting mechanism 3 has a rotating function.

[0036] After the iron core 5 is hung, the gluing operation is started. The operator can adjust the height of the iron core by the lifting function of the lifting mechanism 3, so that the gluing position of the iron core 5 is in a suitable position, which is convenient for the operator to perform the gluing operation. The process is that the fixed frame 301 of the lifting mechanism 3 is connected to the lifting frame 303 through the second guide rail assembly 302, and the lifting motor 305 drives the second lead screw nut assembly 304 to enable the lifting frame 303 to realize the lifting function.

[0037] After the gluing is completed, the three sets of iron cores 5 are adjusted to the same height by the lifting mechanism 3, and the rotating clamping jaw mechanism 4 is further driven to make the three sets of iron cores 5 in a 120° array state, and then the three sets of iron cores move to the center to realize the assembling operation. The process is that the horizontal moving motor 206 drives the first lead screw nut assembly 205 to move the connecting seat 204, so that the lifting mechanism 3 connected thereto through the rotary support 201 realizes horizontal movement.
