Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of manifold drilling tools, and in particular relates to a multi-hole adjustable manifold drilling tool. Background Technology
[0002] A bus is a conductive device used to collect and distribute electrical energy. Buses are generally long and have a large conductive cross-section to carry a large current.
[0003] Existing busbar drilling tools have four holes. When two busbar drilling tools are fixed on both sides of the busbar, the four holes on one tool must be aligned with the four holes on the other tool one by one. This process is time-consuming and prone to errors after drilling. Furthermore, over time, the inner walls of the holes on the drilling tools will be damaged, affecting the drilling quality and accuracy. Therefore, we propose a multi-hole adjustable busbar drilling tool. Utility Model Content
[0004] The purpose of this invention is to provide a multi-hole adjustable manifold drilling tool to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a multi-hole adjustable manifold drilling tool, comprising:
[0006] A fixing plate has two second threaded grooves and an installation groove. Two round holes are formed between the two second threaded grooves and the installation groove. A groove is formed between the two round holes. Slots are formed at the top and bottom of the round holes. A ring is formed in the round hole. A first connecting plate and a second connecting plate, which are fixed to the ring, are respectively inserted into the two slots.
[0007] A fixing component, located within a fixing plate, is used to fix two second connecting plates;
[0008] Two first threaded grooves are formed inside the fixed plate and located on one side of the groove. A locking L-shaped block is provided in the groove. A locking handle is threaded on the locking L-shaped block. Two first hexagon socket head cap screws are threaded on the locking L-shaped block. One end of the first hexagon socket head cap screw extends into the corresponding first threaded groove. A third hexagon socket head cap screw is threaded in the second threaded groove.
[0009] In this technical solution, during use, the operator can first place a fixing plate on one side of the busbar, so that the heads of the two third hexagon socket head cap screws on the fixing plate are located near the busbar, and the heads of the two third hexagon socket head cap screws are in contact with the end of the busbar. At this time, the busbar will be located on top of the fixing plate, and the locking handle will be located above the busbar. Then, the locking handle can be turned by hand. Under the action of the thread, the locking handle will rotate on the locking L-shaped block and move downward until the bottom of the locking handle contacts the busbar, and the two third hexagon socket head cap screws are engaged. Using this method, the fixing plate can be kept stable and the installation can be made faster. Then, the staff can install another fixing plate on the other side of the busbar in the same way. After installation, the center of the round hole on one fixing plate and the center of the corresponding round hole on the other fixing plate are on the same horizontal line, which ensures that the positions of the holes on both sides of the busbar can correspond one by one after drilling. This is conducive to the precise connection and assembly with other components. In addition, the fact that there are only two round holes on the fixing plate makes it easier for novices to operate and ensures the stability of drilling quality.
[0010] When the ring is severely worn and needs to be replaced, the fixing component is used to release the two second connecting plates, allowing the ring to be removed from the circular hole. The first and second connecting plates will also be removed from their corresponding slots. A new ring can then be placed into the circular hole, and the second and first connecting plates on the new ring will enter their corresponding slots. The fixing component then secures the two second connecting plates in their corresponding slots, preventing the ring from rotating.
[0011] In the above technical solution, the fixing component further includes:
[0012] A baffle is provided in the mounting groove. A limiting groove is provided in the fixing plate on one side of the mounting groove. A limiting plate fixed to the baffle is inserted into the limiting groove. One end of the limiting plate extends into two through grooves. Two second hexagon socket head cap screws are threaded on the baffle. One end of each of the two second hexagon socket head cap screws extends into the fixing plate.
[0013] In this technical solution, the operator can use a hex wrench to remove the two second internal hex bolts from the baffle. Then the baffle can be pulled outward, and the limiting plate will also move outward until one end of the limiting plate is pulled out of the two through slots, and the limiting plate is pulled out of the limiting slot. At this time, the two second connecting plates will be released from fixation.
[0014] In the above technical solution, further, one end of the limiting plate is inserted into two through slots, one end of the limiting plate is inserted into the fixing plate, the limiting plate is tightly welded to the baffle, and one end of the second internal hex bolt is threaded to the fixing plate.
[0015] In this technical solution, it is ensured that one end of the limiting plate can be inserted into the two through slots, that one end of the limiting plate can be inserted into the fixing plate, that the structure between the limiting plate and the baffle is stable, and that one end of the second internal hex bolt can be threaded into the fixing plate.
[0016] In the above technical solution, both the second connecting plate and the first connecting plate are tightly welded to the ring.
[0017] In this technical solution, the structural stability between the second connecting plate, the first connecting plate, and the ring is ensured.
[0018] In the above technical solution, the first internal hexagonal bolt is further connected to the first threaded groove.
[0019] In this technical solution, it is ensured that one end of the first internal hex bolt can be threaded into the first threaded groove.
[0020] In the above technical solution, the outer wall of the ring is in contact with the inner wall of the circular hole, and the outer walls of the first connecting plate and the second connecting plate are in contact with the corresponding slots.
[0021] In this technical solution, it is ensured that the ring will not rotate or wobble inside the circular hole.
[0022] In the above technical solution, the limiting plate is further located between the two first internal hexagon bolts.
[0023] In this technical solution, it is ensured that the two first internal hex bolts will not obstruct the displacement of the limiting plate.
[0024] The beneficial effects of this utility model are:
[0025] 1. This multi-hole adjustable manifold drilling tool, through the cooperation of a fixed plate, a locking L-shaped block, a locking handle, two third hexagon socket head cap screws, two second threaded grooves, two first threaded grooves, two first hexagon socket head cap screws, and two round holes, allows for easy and time-saving alignment when the two fixed plates are fixed to both sides of the manifold. This avoids errors after drilling and improves the accuracy of drilling.
[0026] 2. This multi-hole adjustable manifold drilling tool, through the cooperation of the slot, ring, first connecting plate, second connecting plate, through groove, mounting groove, baffle, limit plate and second internal hex bolt, ensures that the damaged ring on the inner wall can be removed and replaced, so as to avoid affecting the quality and accuracy of drilling.
