Description

Technical Field

[0001] The utility model relates to the field of transformer core clamp processing, in particular to a gantry type double-head drilling and milling device for processing core clamps which is provided with a turnover table. Background Art

[0002] The transformer core clamp is an important component inside the transformer, which is used to fix and support the transformer core. One of the characteristics of the transformer core clamp is that there are various types of mounting holes on the clamp web, including through holes, inclined holes, threaded holes, etc. The processing method in the existing technology requires drawing the hole positions on the clamp web, then stamping and drilling with a drill press, while the inclined holes on the web require the use of a machining center with tooling and then milling. Therefore, the core clamp web usually needs to be clamped multiple times to complete the processing, which has problems such as many processing steps, complex processing methods, and long production cycles. The second characteristic of the transformer core clamp is that the overall shape is narrow and long, especially for large transformers, which use a longer clamp web, which makes the core clamp web processing more difficult.

[0003] The existing technology lacks specialized drilling and milling equipment for the webs of core clamps. Patent publication number CN102267052B discloses a fixed-beam, dual-spindle CNC drilling and milling machine. The machine comprises a bed, columns on either side, and a crossbeam at the top of the columns. An X-axis transmission mechanism is located in the middle of the bed, driving the worktable along the X-axis. Centerless spiral chip conveyors are located on either side of the worktable. Two spindle boxes are mounted on the crossbeam, each with a machining tool located on its underside. Both tools have three degrees of freedom of movement in the X, Y, and Z directions, and are capable of automatic tool changing. However, the machine is not suitable for machining oblique holes. For example, the patent with authorization announcement number CN213570161U discloses a single-gantry dual-head cutting and breaking machine, which includes a gantry assembly and two independently movable cutting head assemblies. However, this device is used for glass cutting, so a cutting belt for transmitting glass samples is provided in the middle of the device, and a vacuum system is provided on the cutting belt for adsorbing and fixing the glass samples to ensure that the glass samples do not move during the processing. Similarly, this device can only realize linear movement of the cutter head, and it is not suitable for inclined hole processing.

[0004] In addition, in the existing technology, the processing of inclined holes is mainly completed by the cooperation of fixtures and tooling. For example, patents such as CN212371661U and CN213164183U disclose fixtures and tooling for processing inclined holes, but the above devices are not suitable for processing narrow and long core clamp webs, and the use of fixtures and tooling to assist processing still has problems such as many processing steps and long production cycles.

DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] like Figures 1 to 12 As shown, the utility model includes a workbench and a mobile gantry 1, wherein Figure 2 As shown, the workbench includes a first side platform 12 and a second side platform 13, and the upper end of the first side platform 12 is provided with a first turning platform 4, and the upper end of the second side platform 13 is provided with a second turning platform 5, as shown in FIG. Figure 7 As shown, the first side pedestal 12 and the second side pedestal 13 are both provided with a flip driving device 16, and the first flip table 4 and the second flip table 5 are respectively driven by the corresponding flip driving device 16 to flip toward the inside of the workbench, as shown in FIG. Figures 2-3 As shown, a chip removal groove 7 and a plurality of flip hinge frames 8 are provided between the first side pedestal 12 and the second side pedestal 13. Figure 6 As shown, the inner ends of the first turning platform 4 and the second turning platform 5 are both provided with a plurality of turning hinges 17, and each turning hinge 17 is respectively hinged to the corresponding turning hinge frame 8, thereby realizing the inward turning hinge of the first turning platform 4 and the second turning platform 5. At the same time, the chip removal groove 7 is provided below each turning hinge frame 8 without affecting chip removal. Figure 2 As shown, the first side slide 6 on one side of the mobile gantry 1 is movably arranged on the outside of the first side platform 12, and the second side slide 19 on the other side is movably arranged on the outside of the second side platform 13. The crossbeam of the mobile gantry 1 is provided with a first tool 2 and a second tool 3 that can be independently moved and adjusted. When the utility model is in operation, the first turning table 4 and the second turning table 5 are both provided with a clamping web 14, and the clamping web 14 on the first turning table 4 can be processed by the first tool 2, and the clamping web 14 on the second turning table 5 can be processed by the second tool 3, thereby improving the processing efficiency. Figure 7 As shown, when it is necessary to process the web inclined hole 1401 on the web 14 of the clamp, the first flip table 4 or the second flip table 5 is driven by the corresponding flip drive device 16 to flip and lift to the inside of the workbench to a set angle, and then the second tool 2 or the second tool 3 is actuated to complete the processing of the web inclined hole 1401.

[0033] The movable gantry 1 and the first tool drive mechanism and the second tool drive mechanism thereon are all well-known technologies in the art. For example, the gantry and tool drive structure in the patent CN102267052B can be used. Figure 2 As shown, the first lifting seat 201 and the second lifting seat 301 can realize the Z-direction lifting of the first tool 2 and the second tool 3, the first transverse motor 202 and the second transverse motor 302 can realize the Y-direction transverse movement of the first tool 2 and the second tool 3, and the mobile gantry 1 drives the first tool 2 and the second tool 3 to realize the X-direction movement, as shown in FIG. Figure 3 As shown, a first tool magazine 203 and a second tool magazine 303 are provided on both sides of the mobile gantry 1 to facilitate the replacement of different types of tools.

[0034] But if Figure 2As shown, in order to facilitate processing, the first turning table 4 and the second turning table 5 on the workbench of the utility model are symmetrically arranged and both are hinged at the inner ends to turn inward. At the same time, the chip removal groove 7 is also arranged between the first side platform 12 and the second side platform 13. Therefore, the gantry moving drive mechanism cannot be set in the middle of the workbench of the utility model. Therefore, the utility model is provided with a first drive mechanism on the outside of the first side platform 12, and a second drive mechanism on the outside of the second side platform 13. The first side slide 6 of the movable gantry 1 is driven to move by the first drive mechanism, and the second side slide 19 is moved by the second drive mechanism. The first drive mechanism and the second drive mechanism can adopt appropriate structural forms according to actual needs. For example, the X-axis transmission mechanism including the X-axis screw and the X-axis servo motor in the CN102267052B patent can still be adopted, wherein the first side slide 6 is provided with a first screw which is sleeved on the X-axis screw on the corresponding side, and the second side slide 19 is provided with a second screw which is sleeved on the X-axis screw on the corresponding side. In addition, as shown in FIG. Figure 4 As shown, slide rails 15 are provided on the outer sides of the first side pedestal 12 and the second side pedestal 13, a first slider is provided on the first side slide 6 to cooperate with the slide rail 15 on the corresponding side, and a second slider is provided on the second side slide 19 to cooperate with the slide rail 15 on the corresponding side.

[0035] like Figure 6 As shown, in this embodiment, the first turning table 4 and the second turning table 5 each include a plurality of table plate assemblies, and each set of table plate assemblies is provided with a plurality of table plate positioning holes 18. Figure 8 As shown, the web 14 of the clamp targeted by the present invention is provided with web positioning holes 20 of the same number and layout. When the present invention is working, the platform positioning holes 18 cooperate with the corresponding web positioning holes 20 through positioning pins or positioning bolts, thereby achieving the fixation of the clamp web 14 on the first turning table 4 or the second turning table 5. In this way, even if the first turning table 4 or the second turning table 5 is tilted and turned, the position of the clamp web 14 will not be moved. In addition, since the clamp web 14 is narrow and long, Figure 1 As shown, the utility model is provided with a first turning table 4 and a second turning table 5 of sufficient length to meet the processing needs of clamp webs 14 of different length specifications. During processing, the movable gantry 1 moves along the axial direction of the workbench so that the first tool 2 and the second tool 3 thereon can be moved to the set position on the workbench to complete the processing. In addition, the utility model can also set multiple clamp webs 14 on each turning table at one time, thereby further improving the processing efficiency.

[0036] like Figure 6As shown, in this embodiment, the flip hinge frame 8 includes a mounting plate 803 and a bracket 802, wherein the mounting plate 803 is arranged at the upper end of the chip groove 7, and the bracket 802 is arranged on the mounting plate 803, and two hinged beams 801 are provided at the upper end of the bracket 802, and a hinge slot is formed between the two hinged beams 801, and the flip hinge shaft 17 is provided in the hinge slot and is rotatably connected to the hinged beams 801 on both sides through a connecting shaft. When the flip table flips, the flip hinge shaft 17 rotates around the connecting shaft. This structure facilitates the disassembly and installation of each table plate assembly of the flip table. During disassembly, it is only necessary to pull out the connecting shaft, and the flip hinge shaft 17 can be moved outward to disengage from the hinge slot, and then the table plate can be removed. In this way, the table plate assembly with different table plate positioning hole 18 combinations can be easily replaced according to actual needs, thereby improving the flexibility of use and scope of application of the utility model.

[0037] like Figure 7 As shown, the flip drive device 16 can select a linear drive device such as a cylinder or an oil cylinder according to actual needs. In addition, a hinged seat is provided at the bottom of the first side pedestal 12 and the bottom of the second side pedestal 13, and the lower end of the flip drive device 16 is hinged to the hinged seat, and the upper end of the flip drive device 16 is hinged to the corresponding flip table through a hinge shaft. In addition, the utility model can set a suitable number of flip drive devices 16 in the first side pedestal 12 and the second side pedestal 13 according to actual needs.

[0038] like Figure 1 and Figure 5 As shown, a chip conveyor 9 is provided inside the chip trough 7. In this embodiment, the chip conveyor 9 adopts an automatic flat chain structure, so that after the iron chips fall into the chip trough 7, they can be automatically discharged into the cleaning vehicle through the chip conveyor 9. In addition, the first turning table 4 and the second turning table 5 of the utility model can also cooperate to tilt inward and turn over to allow the iron chips to fall into the chip trough 7. The chip conveyor 9 is a well-known technology in the art and is a commercially available product. For example, a chain plate chip conveyor produced by Qingyun Huade Machine Tool Auxiliary Equipment Manufacturing Co., Ltd. can be used.

[0039] like Figures 1-2 As shown, the present invention can be set on a workshop base 11, and baffles 10 can be set on both sides of the workbench as needed to prevent iron chips from splashing.

[0040] The working principle of this utility model is:

[0041] like Figures 8-12 As shown, the present invention is mainly aimed at processing the clamp web 14, wherein one of the characteristics of the clamp web 14 is that it includes various types of handle mounting holes thereon, and the second specific characteristic is that the overall shape is narrow and long.

[0042] When the utility model is working, the clamp web 14 is first placed on the first turning table 4 and the second turning table 5 respectively, wherein Figure 6 As shown, the first turning table 4 and the second turning table 5 each include a plurality of table plate assemblies, and each set of table plate assemblies is provided with a plurality of table plate positioning holes 18. Figure 8 As shown, the web 14 of the clamp is provided with web positioning holes 20 of the same number and layout, and the table positioning holes 18 cooperate with the corresponding web positioning holes 20 through positioning pins or positioning bolts, so as to achieve the fixation of the clamp web 14 on the first turning table 4 and the second turning table 5. After the clamp web 14 is fixed, the mobile gantry 1 starts to move to the processing position according to the set program, and then the first tool 2 and the second tool 3 on the moving gantry 1 are processed to process the clamp web 14, wherein the clamp web 14 on the first turning table 4 can be processed by the first tool 2, and the clamp web on the second turning table 5 can be processed by the second tool 3. When it is necessary to process the web inclined hole 1401 or the hole chamfer, as shown in FIG. Figure 7 As shown, the first turning table 4 or the second turning table 5 is driven by the corresponding turning driving device 16 to turn inward and lift up to a set angle, and then the second tool 2 or the second tool 3 is actuated to complete the processing of the web inclined hole 1401.

[0043] The utility model improves the processing efficiency, wherein the clamp web 14 can be placed on the first turning table 4 and the second turning table 5, and the first tool 2 and the second tool 3 can cooperate with the first turning table 4 and the second turning table 5 to move independently to complete the processing. Figure 1 As shown, the first turning table 4 and the second turning table 5 have sufficient length, which not only meets the processing needs of clamp webs 14 of different length specifications, but also can set multiple clamp webs 14 at one time along the axial direction of the workbench on each turning table, thereby further improving the processing efficiency.

[0044] The utility model is flexible to use and can be applied to the processing of clamp webs 14 of different specifications, such as Figure 6 As shown, the flip articulated frame 8 of the present invention includes a mounting plate 803 and a bracket 802, and two hinged beams 801 are provided at the upper end of the bracket 802 to form a hinge slot. The flip hinge shaft 17 on the flip table is inserted into the hinge slot and is rotatably connected to the hinged beams 801 on both sides through a connecting shaft. A through hole is provided at the end of the hinged beam 801 for inserting the connecting shaft. When the flip table flips, the flip hinge shaft 17 rotates around the connecting shaft. At the same time, this structure also facilitates the disassembly of each table assembly of the flip table to replace the table assembly with different table positioning hole 18 combinations. When disassembling, the table assembly can be removed by simply pulling out the connecting shaft. In addition to independently moving to complete processing, the first tool 2 and the second tool 3 can also cooperate in processing to meet the processing needs of workpieces of different specifications.
