Description

Technical Field

[0001] The invention relates to the technical field of dry-type transformer production, in particular to a dry-type transformer production positioning tool. Background Art

[0002] A dry-type transformer refers to a transformer whose core and winding are not immersed in insulating oil. It is widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment, etc. Dry-type transformers are mainly divided into three types: open, closed, and cast. Dry-type transformers are safe, fireproof, pollution-free, have high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability, and long service life. When processing the dry-type transformer box, it is necessary to drill holes at the end corners of its surface, and then positioning tooling is required during processing.

[0003] Query the prior art "Announcement No.: CN220295922U is specifically a drilling tool for processing a dry-type transformer box, comprising a processing table, a material blocking seat is fixedly installed on the front side of the processing table, an electric push rod is fixedly installed on the rear side of the processing table, a material clamping seat is fixedly installed on the telescopic end of the electric push rod, a telescopic cylinder is fixedly installed on the upper end of the processing table through an assembly frame, a lifting frame is fixedly installed on the telescopic end of the telescopic cylinder through an assembly block, a motor is fixedly installed in the middle of the upper end of the lifting frame, a driving end of the motor is fixedly connected to a transmission shaft, a transmission gear ring is fixedly sleeved on the surface of the transmission shaft, and drill bits are arranged at the four ends of the bottom side of the lifting frame, and each drill bit is used to synchronously drill holes at each end corner of the surface of the dry-type transformer box, which is beneficial to simplify the drilling processing operation of the dry-type transformer box and improve the drilling work efficiency of the dry-type transformer box".

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that the existing dry-type transformer box drilling equipment moves the dry-type transformer box to adjust the position during use, and drills holes at each end corner of the surface of the dry-type transformer box in turn, resulting in cumbersome drilling operations on the dry-type transformer box.

[0005] In the actual processing process, the following technical problems still exist: First, the specifications and models of the existing dry-type transformers are diverse and of different sizes, that is, the drilling points of the box are different, and the drilling structure of the above-mentioned existing technology can only drill holes at the four corners of a single model box, and cannot realize the adaptive drilling processing of the boxes of transformer products of various models and specifications, which has great limitations. When the dry-type transformer changes the series model for box processing, it is necessary to replace the corresponding drilling structure as a whole to achieve it, that is, the user needs to reserve multiple sets of drilling structures, which greatly increases the production cost. At the same time, the replacement is also time-consuming and labor-intensive, which seriously delays the production and processing efficiency of the dry-type transformer; at the same time, further analysis shows that the drilling operation of the drill rod is greatly affected by the drill rod material and the drill rod temperature. The drill rod will gradually heat up during the long-term box drilling operation. When the drill rod continues to perform the box drilling operation at high temperature, it is easy to become "brittle", that is, break, resulting in a decrease in the service life of the drill rod, and thus delaying the overall progress of the production and processing of the dry-type transformer. Second: When the dry-type transformers of the prior art are produced and processed, the box is not necessarily regular. For example, the irregular surface of the XTS-ML-120 dry-type transformer box also needs to be drilled, but the drilling operation using the traditional vertical structure is difficult to achieve, mainly because of the difficulty in positioning. At the same time, after drilling holes at the corners of the surface of the conventional dry-type transformer box, the box needs to be disassembled and the positioning installation angle needs to be changed before drilling other surfaces can be performed, and most of them are one hole on the side, which makes the production and drilling of dry-type transformers time-consuming and laborious. Third: Although the above-mentioned dry-type transformer production positioning tooling of the prior art has improved the drilling efficiency to a certain extent, due to the generation of drilling waste, the above-mentioned dry-type transformer production positioning tooling of the prior art is not equipped with an auxiliary cleaning structure, resulting in waste everywhere at the workstation. Therefore, the staff need to manually clean up after each dry-type transformer production drilling process is completed, which undoubtedly increases their working hours and causes excessive fatigue. At the same time, the waste is inconvenient to clean up and can also cause skin damage. For this reason, we need a dry-type transformer production positioning tooling. Summary of the invention

One end of the stainless steel flexible tube 105 is connected to a mounting seat 106, and a driving motor 107 is fixedly installed on one side of the mounting seat 106 through a bracket. A drill shaft 108 is also connected to the other side of the mounting seat 106, and the drill shaft 108 is connected to the output shaft of the driving motor 107; in this way, when the driving motor 107 is started, it will drive the drill shaft 108 to rotate synchronously to achieve the drilling operation. In a preferred embodiment, a handle is also provided on the mounting seat, and the staff can operate by holding the handle. The present invention sets the winding disk 104, the stainless steel flexible tube 105, the mounting seat 106, the driving motor 107 and the drill shaft 108. In the initial state, the stainless steel flexible tube drives the drill shaft structure to be wound on the winding disk as a whole, which is a non-use state. When it is necessary to process the drilling points on the side or irregular surface of the dry-type transformer box after positioning and tightening, the staff can take out the stainless steel flexible tube 105 of an appropriate length by hand from the mounting seat, and keep the processing position of the drill shaft 108 at a corresponding angle. In this way, the drilling operation of different positions of the dry-type transformer box can be completed at the same time without disassembly and replacement. At the same time, it can also be used as an alternative for drilling under the forward positioning tooling of the dry-type transformer box, aiming to improve the convenience of operation under the tooling positioning while improving the operating efficiency of the dry-type transformer box production drilling.

[0033] like Figure 1 and Figure 7 As shown in the figure: In this embodiment, the cooling component 6 is used to discharge the cooling liquid synchronously when the drilling device 3 performs the drilling operation at a preset speed to complete the cooling of the drilling hole. Specifically, the cooling component 6 includes a liquid storage tank 601, a liquid pump 602, a branch pipe 603 and a hose 604. Figure 6 As shown: a channel 605 is opened in the center of the drill rod 307, which serves as a flow channel for the coolant. A liquid outlet 606 is provided at the bottom of the channel 605. The liquid outlet is arranged at the lower part of the drill bit and communicates with the outside. A first joint 607 is connected to the top of the channel 605 through a bearing seal. The purpose of such a setting is to ensure that the drill rod as a whole can rotate relatively and ensure basic drilling operations. The first joint 607 is connected to one end of the hose 604 to keep the coolant connected. The liquid storage tank 601 is annular and is arranged on the center plate 313 and is located outside the rotating motor 304. A liquid inlet pipe is connected to one side of the liquid storage tank 601 for liquid replenishment operations. The liquid storage tank 601 has a reasonable structural design and high space utilization. At the same time, it is arranged outside the rotating motor to effectively reduce the noise of the motor drive. As shown Figure 7 As shown: the liquid pump 602 is arranged in the liquid storage tank 601, the input end of the branch pipe 603 is connected to the liquid pump 602, and the output end is connected to the hose 604 through the second joint 608. In a preferred embodiment, as Figure 8 As shown, the branch pipe 603 is composed of an annular water pipe arranged at the bottom and a liquid infusion pipe arranged in the annular water pipe. The liquid infusion pipes are four evenly distributed in an annular shape, and the liquid infusion pipes and the annular water pipe are fixed by welding. The output end of the liquid pump is connected to the annular water pipe, the input end of the liquid infusion pipe is connected to the annular water pipe, and the output end is connected to the hose. When the liquid pump is started, the coolant will flow to the annular water pipe through the output end of the liquid pump, and then pass through the corresponding liquid infusion pipes to the respectively connected hoses, and then enter the drill pipe for cooling.

[0034] The hose 604 is a retractable water hose 604. The purpose of such a setting is to adapt to the change of the adjustable overall area of ​​the substrate, that is, the change of the spacing between the drill rod 307 and the central axis of the central plate 313. Figure 1 As shown: the workbench 1 is provided with a liquid collecting tank 110 in the center, which is convenient for collecting the coolant used for cooling the drill rod above, and the coolant can also take away some drilling waste. Fig. 9 As shown: a filter screen 111 is provided at the upper end of the liquid collecting tank 110; the purpose of providing the filter screen is to block larger particles of drilling waste on the table surface, and then to achieve centralized recycling and reuse through the collection effect of the cleaning plate. The coolant can be cooling water. Filter cotton 112 is provided in the liquid collecting tank 110, and a drain pipe 113 is also connected to the bottom end, and a switch valve is provided on the drain pipe. The purpose of such a setting is that the mixture of waste chips and coolant contains a large amount of iron filings and impurities, which cannot be discharged directly. This embodiment uses filter cotton to filter it to ensure that the drainage meets the environmental discharge requirements.

[0035] When in use, the staff will place the dry-type transformer box workpiece that needs to be punched in a manner that fits the left side wall of the positioning baffle 2 to ensure the first reference, so that the workpiece can be quickly positioned. Then the staff starts the fixed push rod 4, so that the fixed push rod 4 extends to push the push plate 5 to move toward the workpiece and complete the fixation of the workpiece. Next, the staff starts the rotating motor 304 of the drilling device, and the rotating motor 304 will drive the sun gear 305 to rotate synchronously, thereby causing the planetary gear 306 and the drill rod 307 to start rotating as a whole. Next, start the cylinder 303, and the cylinder 303 will drive the drill rod 307 to move downward to complete the simultaneous operation of drilling holes at the four corners of the dry-type transformer box. When it is necessary to drill holes at the end corners of a larger dry-type transformer box, first release the initial limit of the fixing bolt 904 to the clamping rod 901, and the staff pulls the branch plate 314 outward, and the clamping rod 901 and the branch plate 314 are an integrated structure. That is, the clamping rod 901 gradually extends into the clamping slot 902, and the staff precisely controls the clamping rod 901 by observing the scale line and the drilling mark position of the dry-type transformer box. Then the staff installs the fixing bolt 904 to fix the clamping rod 901 again, that is, to determine the position of the branch plate 314. The corresponding rod body is released from the top limit of the limit nut sleeve, and the planetary gear 306 of the appropriate size is disassembled and replaced for tightening and installation again, and the planetary gear 306 is kept matched with the sun gear 305 for installation, and the above drilling steps are repeated.

[0036] When the drill rod 307 continues to work for a preset time, after the actual dry-type transformer box drilling operation is carried out, the preset time is 8-10 box drilling process times. The staff turns on the liquid pump 602, and the liquid pump 602 allows the coolant to flow to the channel 605 in the drill rod 307 through the branch pipe 603-hose 604. While ensuring that the drill rod 307 is sufficiently hard, the channel 605 for the coolant to flow is provided, which can not only quickly cool the drill rod 307 and ensure the service life of the drill rod, but also enable the coolant to drive the waste chips downward into the liquid collecting tank for centralized discharge.

[0037] When the drilling of the dry-type transformer box is completed, the staff will remove the processed workpiece. At this time, the waste chips generated during the drilling process will remain on the top of the workbench. At this time, the staff starts the mobile motor 703, and the output end of the mobile motor 703 drives the screw rod 702 to rotate. The rotating screw rod 702 will drive the mobile block 701 to move, so that the mobile block 701 drives the cleaning plate 101 to move, and then the cleaning plate 101 can easily push the drilling waste chips on the workbench 1 into the collection box for cleaning. After the cleaning is completed, the staff controls the output end of the mobile motor 703 to reverse and drives the cleaning plate 101 to reset through the screw rod 702, so that the staff can carry out the next processing.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
