Description

Technical Field

[0001] This utility model relates to the field of transformer assembly technology, and more specifically, to a transformer core clamp assembly workbench. Background Technology

[0002] The transformer core is the core component for electrical energy conversion. It forms a closed magnetic circuit through the stacking of silicon steel sheets, providing a low-resistivity path for the coils, directly affecting the transformer's energy efficiency and operational stability. Traditional core assembly involves the following steps: first, silicon steel sheets are stacked layer by layer on a table; then, one side of the sheets is fixed using clamps; next, it is moved to a low platform, flipped vertically, and its bottom is initially clamped; then, the coils are assembled, the top silicon steel sheets are assembled, and the upper clamps are fixed. Several drawbacks of this process make assembly cumbersome. Firstly, the initial clamping requires lifting the stacked silicon steel sheets before clamping, which can cause movement due to the weight of the sheets. Secondly, the low platform after clamping is used because subsequent assembly operations require access from the top of the core, and the higher angle after flipping makes assembly difficult. Therefore, there is an urgent need to develop a dedicated workbench for assembling transformer core clamps to optimize the process and simplify operations. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a transformer core clamp assembly workbench to solve the aforementioned problems.

[0004] This utility model is implemented as follows:

[0005] A transformer core clamp assembly workbench includes a lifting table and a core clamp assembly. The lifting table includes a work surface and two lifting legs. Three movable holes are respectively opened on the top two sides of the work surface. The two lifting legs are movably disposed in the opposite movable holes. A transmission assembly is provided at the bottom of the work surface for adjusting the position of the work surface on the lifting legs. A placement groove is opened at the top of the work surface, and the core clamp assembly is disposed at the placement groove, which includes a right-angle baffle and a workbench vise arranged opposite each other along the placement groove.

[0006] Furthermore, the lifting outrigger includes three square tubes arranged side by side, each square tube having a guide rail on one side, wherein the two side square tubes are guide square tubes and the middle square tube is a lifting square tube. A guide slider is provided below the worktable on one side of the movable hole. The guide rail is respectively arranged together with the adjacent guide slider. A crossbar is welded to the top of the lifting square tube and the guide square tube, the crossbar being located above the worktable. A base is welded to the bottom of the lifting square tube and the guide square tube.

[0007] Furthermore, the transmission assembly includes a rack, a transmission rod, and a rotary handle. There are two racks, each disposed on one side of the lifting square tube. A first fixed seat is disposed on the bottom of the worktable near the lifting square tube. The transmission rod is disposed on the two first fixed seats. Both ends of the transmission rod have transmission gears that mesh with the racks. A first helical gear is disposed on the side of the transmission rod near either of the transmission gears. A second fixed seat and a third fixed seat are also disposed on the bottom of the worktable. The rotating shaft of the rotary handle is disposed on the second fixed seat and the third fixed seat. A second helical gear that meshes with the first helical gear is disposed at the end of the rotating shaft of the rotary handle.

[0008] Furthermore, a locking screw is provided on one side of the second fixing seat. When the locking screw is tightened, its end abuts against the shaft of the rotating handle.

[0009] Furthermore, there are two right-angle baffles, which are arranged side by side on the rear side of the placement slot, and the rear side of the right-angle baffles is provided with reinforcing ribs.

[0010] Furthermore, two clamping grooves are spaced apart on the front side of the worktable, with the ends of the clamping grooves close to the placement groove.

[0011] Furthermore, the workbench vise includes a mounting base, a lead screw, and a clamping end. The mounting base is located on the top front side of the clamping groove, and the bottom of the clamping end has a slider that is slidably disposed in the clamping groove. The lead screw is threadedly connected to the mounting base, and the end of the lead screw is movably disposed on the front side of the clamping end.

[0012] The beneficial effects of this utility model are as follows: This workbench integrates a lifting table and a core clamping assembly, optimizing the core assembly process. The lifting table uses three square tubes as lifting legs, two of which are guide square tubes and one is a lifting square tube. Each is equipped with guide rails and guide sliders below the workbench surface to ensure smooth lifting. The transmission assembly consists of a rack, a transmission rod, and a rotating handle. By manually rotating the handle, the lifting square tube is driven to move vertically along the guide rails via helical gear meshing, thereby adjusting the height of the workbench surface. The core clamping assembly includes a right-angle baffle and a workbench vise. The right-angle baffle is fixed to the rear side of the placement slot, and the workbench vise is driven by a lead screw to move the clamping end along the clamping groove, achieving lateral compression and fixation of the core. The lower clamp is directly fixed to the workbench, eliminating the lifting step after stacking silicon steel sheets in the traditional process, avoiding the risk of misalignment of silicon steel sheets caused by manual handling, and reducing labor intensity; the height of the workbench can be adjusted by the lifting table, so that when the iron core is assembled vertically after being flipped, the operator does not need to bend over or use a low platform, which significantly improves the comfort and safety of the operation; the combination of right-angle baffle and workbench vise ensures that the iron core maintains verticality and positional stability during flipping and assembly, reduces errors caused by manual adjustment, and improves the consistency of assembly quality.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] like Figure 1-3 As shown, this utility model provides a transformer core clamp assembly workbench, including a lifting table 10 and a core clamp assembly 30. The lifting table 10 includes a worktable surface 11 and two lifting legs 12. Three movable holes 1101 are respectively opened on the top two sides of the worktable surface 11. The two lifting legs 12 are movably arranged in the opposite movable holes 1101. A transmission assembly 20 is provided at the bottom of the worktable surface 11. The transmission assembly 20 is used to adjust the position of the worktable surface 11 on the lifting legs 12. A placement groove 1102 is opened at the top of the worktable surface 11. The core clamp assembly 30 is provided at the placement groove 1102, which includes a right-angle baffle 31 and a worktable vise 32 arranged opposite to each other along the placement groove 1102.

[0022] In this embodiment, the lifting support leg 12 includes three square tubes arranged side by side. Each square tube has a guide rail 1203 on one side. The two side square tubes are guide square tubes 1202, and the middle one is a lifting square tube 1201. A guide slider 13 is provided below the worktable 11 on one side of the movable hole 1101. The guide rail 1203 is arranged together with the adjacent guide slider 13. A crossbar is welded to the top of the lifting square tube 1201 and the guide square tube 1202. The crossbar is located above the worktable 11, that is, the crossbar limits the maximum lifting height of the worktable 11. A base is welded to the bottom of the lifting square tube 1201 and the guide square tube 1202.

[0023] like Figure 3 As shown, the transmission assembly 20 includes a rack 21, a transmission rod 22, and a rotary handle 24. There are two racks 21, which are respectively disposed on one side of the lifting square tube 1201. A first fixed seat 23 is disposed on the bottom of the worktable 11 near the side of the lifting square tube 1201. The transmission rod 22 is disposed on the two first fixed seats 23. Both ends of the transmission rod 22 have transmission gears that mesh with the rack 21. A first helical gear 2201 is disposed on the side of the transmission rod 22 near any one of the transmission gears. A second fixed seat 25 and a third fixed seat 26 are also disposed on the bottom of the worktable 11. The rotating shaft of the rotary handle 24 is disposed on the second fixed seat 25 and the third fixed seat 26. A second helical gear 2401 that meshes with the first helical gear 2201 is disposed at the end of the rotating shaft of the rotary handle 24.

[0024] Furthermore, a locking screw 2501 is provided on one side of the second fixed seat 25. When the locking screw 2501 is tightened, its end abuts against the rotating shaft of the rotating handle 24, thereby achieving self-locking of the lifting table 10 during the lifting process through the locking screw 2501.

[0025] In this embodiment, there are two right-angle baffles 31, arranged side by side on the rear side of the placement slot 1102, and the rear side of the right-angle baffles 31 is provided with reinforcing ribs. It should be noted that the spacing between the two right-angle baffles 31 is based on the size of the silicon steel sheet 40, specifically as follows: Figure 4 As shown, when the silicon steel sheet 40 is assembled on the table, the right-angle baffle 31 is located between the gaps formed by the vertical ends of the silicon steel sheet 40.

[0026] like Figure 2 As shown, two clamping grooves 33 are spaced apart on the front side of the worktable 11, with the ends of the clamping grooves 33 close to the placement groove 1102.

[0027] Furthermore, the workbench vise 32 includes a mounting base 3201, a lead screw 3202, and a clamping end 3203. The mounting base 3201 is located on the top front side of the clamping groove 33. The bottom of the clamping end 3203 has a slider that is slidably disposed in the clamping groove 33. The lead screw 3202 is threadedly connected to the mounting base 3201, and the end of the lead screw 3202 is movably disposed on the front side of the clamping end 3203.

[0028] Examples, such as Figure 4 As shown, the lower clamping plate 41 of the iron core clamp is first placed on the workbench 11 near the placement slot 1102. At the same time, its position is adjusted so that the connecting corner plates at the bottom of the lower clamping plate 41 are located inside the placement slot 1102, ensuring that the top of the lower clamping plate 41 is parallel to the workbench 11. Then, the silicon steel sheets 40 are stacked. After stacking, the upper clamping plate 42 of the iron core clamp is directly assembled. This process omits the step of lifting the silicon steel sheets 40 to avoid misalignment during lifting. Furthermore, the lifting table 10 is lowered to a suitable position by the transmission component 20 to provide a better viewing angle and height for subsequent assembly operations. Then, the initially assembled iron core clamp is flipped to a state perpendicular to the workbench 11. At this time, the screw 3202 on the workbench vise 32 is rotated so that its clamping end 3203 presses against the side of the iron core clamp, thereby moving it to contact the right-angle baffle 31, thus achieving clamping and fixing. After this process, the subsequent coil assembly and the top silicon steel sheet 40 assembly work can be carried out.

[0029] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
