Description

Technical Field

[0001] The utility model relates to the technical field of iron core processing devices, in particular to an automatic oil removal device for iron cores before welding. Background Art

[0002] With the continuous advancement of automation in the production of new energy motor cores, various core processing steps are also trending towards automation. For example, before welding, the cores must be degreased from the oil added during processing, especially from the outer core walls. A clean outer core wall is the prerequisite and guarantee for effective core welding. However, existing core degreasing processes are no longer able to meet the growing demands of automated production lines. Manual loading and unloading of cores is time-consuming and labor-intensive, while manually operating a high-pressure spray gun to blow air can result in uneven cleaning or ineffective results.

[0003] In the prior art, there is a stator core pressurized oil removal device with application number 202321601793.3, which discloses that a down-pressing module drives a down-pressing rod and a down-pressing head to press the stator core so that the oil on the fan-shaped pieces inside the stator core is pressurized and overflows, and then a lifting module drives the annular connecting plate and the air blowing nozzle to descend to blow air to clean the oil overflowed from the side of the stator core. However, the down-pressing module and the lifting drive module act separately, which increases the complexity of its structure and control. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic oil removal device for iron core before welding. The translation component drives the carrying tooling and the product to move to the bottom of the lower pressure plate. The lower pressure cylinder drives the lower pressure plate to press the iron core downward to squeeze out the oil. The air nozzle is used to blow air downward to separate the oil from the outer wall of the iron core, ensuring that the welding process is not affected by the oil, and the welding quality and connection strength can be guaranteed.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an automatic oil removal device for iron core before welding, comprising a machine platform, and:

The bracket is arranged on the machine platform, the lower pressure cylinder is arranged on the bracket, and a mounting plate is provided at the output end. The lower pressure plate is arranged on the mounting plate through the connecting column. The lower pressure plate is provided with a plurality of air nozzles connected to the air source and opening downward. The lower pressure plate is driven to abut against the iron core on the supporting tooling located below it, and the air nozzles blow air onto the outer wall of the iron core.

[0008] As a further optimization, the lower pressure plate includes a top plate and a bottom plate, the air nozzle is formed on the bottom plate and passes through the bottom plate, the upper end of the bottom plate is provided with a ventilation groove connecting each air nozzle, and the top plate is provided with an air inlet connected to the air source. The top plate is installed on the bottom plate, and the air inlet is connected to the ventilation groove.

The lifting cylinder is arranged on the mounting plate, and the protective cover is arranged at the output end of the lifting cylinder and is located below the mounting plate. The protective cover is driven to abut against the carrying tooling, and can have a good sealing effect to prevent oil from splashing everywhere during blowing cleaning.

[0010] As a further optimization, a clearance hole is provided at the upper end of the protective cover for the connecting column to pass through, so as to avoid affecting the relative movement between the protective cover and the connecting column.

[0011] As a further optimization, the oil removal mechanism also includes a rotary drive assembly, which includes a bearing, a first gear ring, a rotary motor and a second gear ring. The bearing is arranged on a mounting plate, the connecting column is arranged in the bearing and is sleeved with the first gear ring, the rotary motor is arranged on the mounting plate, and the output end is provided with a second gear ring meshing with the first gear ring, so that the lower pressure plate and the air nozzle can be rotated by a certain angle relative to the iron core. After the lower pressure plate and the iron core are re-connected, the air nozzle can act on different positions of the iron core to ensure a cleaning effect.

[0012] As a further optimization, the rotation drive assembly is located above the protective cover.

[0013] As a further optimization, the carrying tooling includes a support plate and a surrounding plate arranged at the upper edge of the support plate.

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figures 1 to 3 , combined Figure 6As shown, an automatic degreasing device for iron core before welding includes a machine 10, a carrying mechanism 20 and a degreasing mechanism 30. For example, three carrying mechanisms 20 are provided on the machine 10, and a degreasing mechanism is matched with each carrying mechanism 20. The carrying mechanism 20 includes a translation component 21 and a carrying tool 22. The translation component 21 is provided on the machine 10 and a linear module can be selected. The carrying tool 22 is provided on the translation component 21 for carrying the iron core 100. The degreasing mechanism 30 includes a bracket, a lower pressure cylinder 31, a mounting plate 321, a connecting column 322 and a lower pressure plate 323. The bracket includes a bracket provided on the machine 10. The lower pressure cylinder 31 is mounted on the support plate 302, and its output end passes through the support plate 302 and is provided with a mounting plate 321. The lower pressure plate 323 is mounted on the mounting plate 321 via a connecting column 322. The lower pressure plate 323 is provided with a plurality of downward-facing air nozzles 320 connected to an air source. The lower pressure plate 323 is driven to abut against the iron core 100 on the supporting fixture 22 below it, and the air nozzles 320 blow air onto the outer wall 100 of the iron core. The upper end of the iron core 100 is entirely located within the central lower pressure area 3230 of the lower pressure plate 323, and the air nozzles 320 are located to the side of the central lower pressure area 3230.

[0028] In the present invention, the product 100 is positioned and placed on the supporting tooling 22, and the translation assembly 21 drives the supporting tooling 22 and the product 100 to move to the bottom of the lower pressure plate 323 of the oil removal mechanism 30. The lower pressure cylinder 31 drives the lower pressure plate 323 to move downward and abuts against the upper end of the iron core 100. The oil between the multiple iron sheets can be squeezed out through the downward pressure action, and the extruded oil covering the outer wall of the iron core 100 or the oil remaining in the previous processing step is blown downward through the multiple air nozzles 320 arranged on the lower pressure plate 323 so that the oil is separated from the outer wall of the iron core 100, and the multiple welding positions 102 on the outer wall of the iron core 100 that need to be welded are cleaned in place to ensure that the welding process is not affected by the oil, and the welding quality and the connection strength of the iron core 100 are guaranteed.

[0029] Preferably, a guide cylinder 34 is provided on the mounting plate 321 , and the guide cylinder 34 is sleeved on the support rod 301 of the cylindrical structure on the bracket, so that the oil removal mechanism 30 can move up and down stably and accurately.

[0030] Continue as Figure 3As shown, the lower pressure plate 323 includes a top plate 3231 and a bottom plate 3232, the air nozzle 320 is formed on the bottom plate 3232 and passes through the bottom plate 3232, the upper end of the bottom plate 3232 is provided with a ring-shaped ventilation groove (not shown) connecting each air nozzle 320, and the top plate 3231 is provided with an air inlet hole (not shown) connected to the air source, the top plate 3231 is installed on the bottom plate 3232, and the air inlet hole is connected to the ventilation groove, and is connected to the air source through a conduit, that is, the flowing air generated by the air source enters the ventilation groove sealed by the top plate 3231 and the bottom plate 3232 through the air inlet hole, and then enters each air nozzle 320 through the transportation and distribution of the ventilation groove, thereby achieving the blowing effect on multiple locations of the outer wall of the iron core 100.

[0031] Preferably, the oil removal mechanism 30 further includes a cover assembly, which includes a lifting cylinder 331 and a protective cover 332. The lifting cylinder 331 is disposed on the mounting plate 321 and can move synchronously with the lower pressure plate 323 and the air nozzle 320. The protective cover 332 is disposed at the output end of the lifting cylinder 331 and is located below the mounting plate 321. The protective cover 332 is driven to abut against the supporting fixture 22. When the lower pressure plate 323 abuts the upper end of the iron core 100, the lifting cylinder 331 drives the protective cover 332 to move downward and abut against the supporting fixture 22, thereby placing the iron core 100 in a relatively sealed space. When the air nozzle 320 blows air to clean the outer wall of the iron core 100, oil splashing can be avoided, thereby ensuring a clean working environment.

[0032] Furthermore, a clearance hole is provided at the upper end of the protective cover 332 for the connecting column 322 to pass through. By sleeved on the connecting column through the clearance hole, the relative movement between the two is not affected and a better sealing effect can be achieved.

[0033] Continue as Figure 3As shown, in another embodiment of the present invention, the oil removal mechanism 30 further includes a rotation drive assembly, which includes a bearing 3241, a first gear ring 3242, a rotating motor 3243 and a second gear ring 3244. The bearing 3241 is arranged on the mounting plate 321, and the connecting column 322 is arranged in the bearing 3241, and the first gear ring 3242 is fixedly sleeved on its outer wall. The rotating motor 3243 is arranged at the bottom end of the mounting plate 321, and the output end is provided with a second gear ring 3244 engaged with the first gear ring 3242, that is, the pressing plate 323 and the air nozzle 320 are set to a rotatable form. When the pressing plate 323 is driven to abut against the upper end surface of the iron core 100, the multiple air nozzles 320 can blow air to clean the outer wall of the iron core 100, but The direction of action of the air nozzle 320 is limited, which may result in a better cleaning effect on the side wall in the direction of the air nozzle 320, while the cleaning effect on the areas on both sides thereof is poor. In order to avoid affecting the cleaning effect by opening more air nozzles 320 on the lower pressure plate 323, the lower pressure cylinder 31 can drive the mounting plate 321 to move up a certain position after partially cleaning the outer wall of the above-mentioned iron core 100, and the second gear ring 3244 is driven by the rotating motor 3243 to drive the first gear ring 3242 and the connecting column 322 to rotate a certain angle, so that the air nozzle 320 can be opposite to the side wall of the iron core 100 at a weaker cleaning position, and then driven down to a certain position by the lower pressure cylinder 31 for air blowing cleaning, which can ensure that the entire side wall of the iron core 100 has a better cleaning effect.

[0034] Preferably, the rotary drive assembly is located above the protective cover 332, which can ensure that the clearance hole has a smaller area to ensure sealing performance, and avoid placing the rotary drive assembly inside the protective cover 332 to avoid contamination due to oil splashing during air blowing cleaning.

[0035] like Figure 4 and Figure 5 , and combined Figure 6 As shown, the carrying tooling 22 includes a support plate 221 and a surrounding plate 222 arranged at the upper side of the support plate 221. The support plate 221 is provided with a groove 220 for storing oil near the surrounding plate 222. The oil cleaned by air blowing can move downward along the side wall of the iron core 100 and be temporarily stored in the groove 220, which can prevent the oil from flowing disorderly and contaminating other components on the carrying tooling 22, or contaminating the translation assembly 21 and the machine 10, and can ensure the cleanliness of the entire equipment. It is only necessary to clean the carrying tooling 22 regularly.

[0036] Preferably, the supporting fixture 22 is provided with a plurality of positioning rods 223 to ensure the stability of the core 100 when being translated or pressed downward.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
