Description

Technical Field

[0002] In the transformer withstand voltage measurement process, a transfer device is usually required to transfer the transformer between the conveying slide rail and the measuring equipment. The existing transfer device usually grabs the transformer in a clamping manner, and the number of transformers that can be grabbed at one time is small. In addition, the transfer device usually needs to move back and forth between the conveying slide rails on both sides of the measuring equipment, resulting in poor feeding continuity and low measurement efficiency. Utility Model Content

[0003] The utility model aims to address the deficiencies of the prior art and to provide an automatic transport tool for transformer withstand voltage measurement which has a simple structure and can continuously transport multiple transformers.

[0006] In the above-mentioned automatic transfer tooling for transformer withstand voltage measurement, the connecting plate is in a "├" shape, the positioning plate is in an L shape and connected to the lower end of the connecting plate, and the lifting magnetic suction component is arranged at the front end of the connecting plate.

[0007] In the above-mentioned automatic transfer tooling for transformer withstand voltage measurement, the lifting and magnetic attraction assembly includes a second lifting cylinder arranged on the connecting plate, a mounting strip plate on the piston rod of the second lifting cylinder, a mounting groove at the lower end of the mounting strip plate, and a detachable magnetic strip in the mounting groove.

[0009] After the utility model adopts the above structure, the two magnetic suction components synchronously absorb the incoming material end of the conveying slide rail and the transformer on the measuring equipment, and the next round of loading can be carried out while the measuring equipment is unloading, which can ensure the continuity of loading and effectively improve the measuring efficiency.

[0010] At the same time, the use of a magnetic suction component to absorb the transformer can avoid deformation of components such as pins on the transformer due to excessive clamping force or offset clamping position compared to existing clamping methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] See also Figure 1-3 As shown, the utility model is an automatic transfer tool for transformer withstand voltage measurement, comprising a horizontal moving component 1, a lifting component 2 is provided on the horizontal moving component 1, a mounting plate 3 is provided on the lifting component 2, and two magnetic suction components 4 that can absorb multiple transformers are symmetrically provided on the mounting plate 3. The conveying slide rail at the incoming material end and the transformer on the measuring device are synchronously sucked by the two magnetic suction components, and the next round of loading can be carried out while the measuring device is unloaded, which can ensure the continuity of loading and effectively improve the measurement efficiency.

[0017] At the same time, the use of a magnetic suction component to absorb the transformer can avoid deformation of components such as pins on the transformer due to excessive clamping force or offset clamping position compared to existing clamping methods.

[0018] In this embodiment, preferably, the magnetic attraction component 4 includes a first lifting cylinder 4a arranged on the mounting plate 3, and a connecting plate 4b is provided on the piston rod of the first lifting cylinder 4a; a lifting magnetic attraction component 5 is provided on the connecting plate 4b, and a positioning plate 4c made of non-magnetic material and with a relatively thin thickness is provided below the lifting magnetic attraction component 5; when the lower surface of the positioning plate 4c contacts the transformer, the lifting magnetic attraction component 5 moves down to the upper surface of the positioning plate 4c and adsorbs the transformer; when the transformer moves into place, the lifting magnetic attraction component 5 rises, and the transformer is separated from the positioning plate 4c.

[0019] When the transformer is being sucked, the piston rod of the first lifting cylinder extends to make the lower surface of the positioning plate contact the transformer, and the lifting magnetic suction component moves down to fit the upper surface of the positioning plate to suck the transformer. When the transformer is moved into place, the lifting magnetic suction component rises and separates from the upper surface of the positioning plate, and the transformer is separated from the lower surface of the positioning plate to complete the transfer. Compared with the pulse electromagnet structure, this structure is simpler and easier to maintain.

[0020] Preferably, the connecting plate 4b is in a "├" shape, the positioning plate 4c is in an L shape and connected to the lower end of the connecting plate 4b, and the lifting magnetic suction component 5 is arranged at the front end of the connecting plate 4b. This structure is convenient for the installation of the connecting plate and the positioning plate, and the structure is simple. In addition, other structures can also be adopted, such as the vertical section of the positioning plate is directly fixed on the lifting magnetic suction component, and another bracket is set on the first lifting cylinder or the lifting magnetic suction component to fix the positioning plate.

[0021] Further preferably, the lifting magnetic attraction assembly 5 includes a second lifting cylinder 5a arranged on the connecting plate 4b, a mounting strip plate 5b on the piston rod of the second lifting cylinder 5a, a mounting groove 5c is provided at the lower end of the mounting strip plate 5b, and a magnetic strip 5d is detachably provided in the mounting groove. The cooperation between the magnetic strip and the positioning plate is controlled by the piston rod of the second lifting cylinder to achieve the purpose of pulsed magnetic attraction. The use of the mounting groove to set the magnetic strip facilitates the disassembly and replacement of the magnetic strip.

[0022] In this embodiment, the horizontal moving assembly 1 includes a horizontal track 1a, a sliding seat 1b is provided on the horizontal track 1a, and a screw rod 1c for driving the sliding seat 1b is provided on the horizontal track 1a; the lifting assembly 2 is arranged on the sliding seat 1b; an infrared sensor 1d is provided on the horizontal track 1a, and a sensing sheet 1e matched with the infrared sensor 1d is provided on the sliding seat 1b. The travel of the screw rod is controlled by the sensing sheet and the infrared sensor to ensure that the transformer is accurately transported to the right place.

[0023] During use, when the transformer is transported to one side of the measuring equipment on the conveying slide rail, the lifting assembly, the first lifting cylinder and the second lifting cylinder piston rod are extended in sequence to make the lower surface of the positioning plate close to the transformer for absorption, the lifting assembly rises, the screw rod drives the sliding seat forward to move the transformer above the measuring equipment, and then the lifting assembly descends to place the transformer on the measuring equipment, the second lifting cylinder and the first lifting cylinder piston rod rise in sequence, and finally the lifting assembly rises, and the screw rod drives the sliding seat to return to its position.

They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
