Description

Technical Field

[0001] This invention relates to the field of drilling tooling technology, and in particular to a drilling and fixing device for a conductive rod. Background Technology

[0002] In the manufacturing and maintenance of power equipment, conductive rods, as key conductive components, often require drilling to connect or install with other parts according to assembly requirements. Since conductive rods are mostly made of metal (such as copper, aluminum, and steel), and some are designed as hollow structures for heat dissipation and weight reduction, the fixing accuracy and stability during the drilling process directly affect the processing quality. Improper fixing can lead to hole misalignment, coaxiality deviation, and even deformation of the conductive rod due to excessive clamping force (especially for hollow conductive rods), thus affecting conductivity and equipment assembly accuracy.

[0003] Traditional methods of fixing conductive rods by drilling have many limitations: for example, when using rigid clamps to hold them directly, the friction between the metal clamps and the conductive rods is limited, making them prone to slippage during drilling vibrations. Furthermore, the rigid clamping force is difficult to control precisely, which can easily cause damage or deformation to the surface of the conductive rods. Summary of the Invention

[0004] This invention provides a drilling and fixing device for conductive rods to solve the problem that existing tooling can easily cause deformation or surface damage to conductive rods when fixing them.

[0005] To alleviate the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0006] A drilling and fixing device for a conductive rod includes a first fixing mechanism. The first fixing mechanism includes a base, on which two fixing brackets are symmetrically arranged. Each of the two fixing brackets has an insertion hole for inserting the conductive rod in the middle. Each of the two fixing brackets has a pull plate on both sides. A rubber strip and a leather strip are fixedly connected to the opposite surfaces of the two pull plates, and both ends of the rubber strip and the leather strip are fixedly connected to the pull plate. The conductive rod is inserted into the space between the rubber strip and the leather strip and the corresponding pull plate in the insertion hole. When the two pull plates move away from each other, the rubber strip and the leather strip can be tightened so that the conductive rod is coaxial with the insertion hole.

[0007] Furthermore, there are three rubber straps and three leather straps, two of which are fixedly connected to the same pull plate, and the other rubber strap and leather strap are fixedly connected to the pull plate on the opposite side. The single rubber strap and leather strap are located in the middle of the two rubber straps and leather straps, respectively.

[0008] Furthermore, a first hydraulic rod is fixedly connected to each of the two pull plates, and the output end of the first hydraulic rod passes through the pull plate and is fixedly connected to the fixing frame.

[0009] Furthermore, it also includes a second fixing mechanism, which includes mounting seats symmetrically arranged on both sides of the base. Each of the two mounting seats is equipped with a frustum column. When the two frustum columns are close to each other, they can apply pressure to the conductive rod to fix the conductive rod.

[0010] Furthermore, a second hydraulic rod is fixedly connected to the mounting base, and the output end of the second hydraulic rod is fixedly connected to the frustum column.

[0011] Furthermore, it also includes an adjustment mechanism, which includes screws fixedly connected to the opposite faces of the two fixed frames. The ends of the two screws are threadedly connected to a threaded cylinder, and the threads of the two screws are in opposite directions, so that when the threaded cylinder rotates, it can drive the two fixed frames to move closer or further apart.

[0012] Furthermore, a rotating base is fixedly connected to the base, and the threaded cylinder is rotatably connected to the rotating base.

[0013] Furthermore, a motor is fixedly connected to the base, and gears are fixedly connected to both the output end of the motor and the threaded cylinder, with the two gears meshing with each other.

[0014] The beneficial effects of this invention are analyzed as follows:

[0015] A drilling and fixing device for a conductive rod includes a first fixing mechanism. The first fixing mechanism includes a base, on which two fixing brackets are symmetrically arranged. Each fixing bracket has an insertion hole for inserting the conductive rod in the middle. Each fixing bracket has a pull plate on both sides. A rubber strip and a leather strip are fixedly connected to the opposite surfaces of the two pull plates, and both ends of the rubber strip and the leather strip are fixedly connected to the pull plate. The conductive rod is inserted into the space between the rubber strip and the leather strip and the corresponding pull plate in the insertion hole. When the two pull plates move away from each other, the rubber strip and the leather strip can be tightened so that the conductive rod is in a position coaxial with the insertion hole.

[0016] When drilling holes in the conductive rod, first control the two pull plates to move closer together, thus expanding the intersection space of the leather strap and rubber strap to facilitate the passage of the conductive rod. After the conductive rod passes through the two holes and the intersection space of the leather strap and rubber strap within the holes, control the two pull plates to move away from each other. This causes the leather strap and rubber strap to pull the conductive rod symmetrically, and the lengths of the leather strap and rubber strap are equal. This allows the conductive rod to be fixed in a position close to the coaxiality of the holes. Furthermore, the contact friction between the rubber strap and leather strap and the conductive rod is relatively large, and their hardness is lower than that of the conductive rod, thus ensuring that the conductive rod is fixed without deforming.

[0025] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] like Figures 1-5 As shown, a drilling and fixing device for a conductive rod includes a first fixing mechanism 100. The first fixing mechanism 100 includes a base 110, on which two fixing brackets 120 are symmetrically arranged. Each fixing bracket 120 has an insertion hole 130 for inserting a conductive rod in its middle. Each fixing bracket 120 has a pull plate 160 on both sides. A rubber strip 140 and a leather strip 150 are fixedly connected to the opposite surfaces of the two pull plates 160, and both ends of the rubber strip 140 and the leather strip 150 are fixedly connected to the pull plate 160. The conductive rod is inserted into the space between the rubber strip 140 and the leather strip 150 and the corresponding pull plate 160 in the insertion hole 130. When the two pull plates 160 move away from each other, the rubber strip 140 and the leather strip 150 can be tightened so that the conductive rod is in a position coaxial with the insertion hole 130.

[0029] The working mechanism of the drilling and fixing device for the conductive rod provided in this embodiment is as follows:

[0030] When drilling holes in the conductive rod, first control the two pull plates 160 to move closer together, thus expanding the intersection space of the leather strap 150 and the rubber strap 140 to facilitate the passage of the conductive rod. After the conductive rod passes through the two insertion holes 130 and the intersection space of the leather strap 150 and the rubber strap 140 within the insertion holes 130, control the two pull plates 160 to move away from each other. This causes the leather strap 150 and the rubber strap 140 to pull the conductive rod symmetrically. Since the lengths of the leather strap 150 and the rubber strap 140 are equal, the conductive rod can be fixed to a position close to the coaxiality of the insertion holes 130. Furthermore, the contact friction between the rubber strap 140 and the leather strap 150 and the conductive rod is relatively large, and their hardness is lower than that of the conductive rod, thus ensuring that the conductive rod is fixed without deformation.

[0031] Among the optional methods in this embodiment, the more preferred one is:

[0032] There are three rubber straps 140 and three leather straps 150. Two rubber straps 140 and leather straps 150 are fixedly connected to the same pull plate 160, and the other rubber strap 140 and leather strap 150 are fixedly connected to the pull plate 160 on the opposite side. The single rubber strap 140 and leather strap 150 are located in the middle of the two rubber straps 140 and leather straps 150, respectively.

[0033] Three rubber strips 140 form a group, and three leather strips 150 form a group. Two rubber strips 140 are fixedly connected to the same pull plate 160, and the remaining rubber strip 140 is fixedly connected to another pull plate 160. The single rubber strip 140 is located in the middle of the two rubber strips 140. The arrangement of the leather strips 150 is the same as that of the rubber strips 140. The rubber strips 140 and the leather strips 150 are divided into two groups, so that when the two pull plates 160 are far apart, the deformation amplitude of the rubber strips 140 or leather strips 150 in the same group is approximately the same, thereby allowing the conductive rod to be fixed at a position close to the socket 130.

[0034] In addition, another set of pull plates 160 can be set up so that the rubber belt 140 and the leather belt 150 are connected to the two sets of pull plates 160 respectively, so as to adapt to the different elastic stiffness coefficients of the two, so that the two sets of pull plates 160 are separated from each other by different distances to ensure the fixing effect of the conductive rod.

[0035] Among the optional methods in this embodiment, the more preferred one is:

[0036] A first hydraulic rod 170 is fixedly connected to each of the two pull plates 160. The output end of the first hydraulic rod 170 passes through the pull plate 160 and is fixedly connected to the fixing frame 120.

[0037] When the first hydraulic rod 170 extends, it can drive the pull plate 160 away from the fixed frame 120. By controlling the extension length of the first hydraulic rod 170, the tension of the rubber belt 140 and the leather belt 150 on the conductive rod can be controlled. A pressure sensor can also be set at the contact point between the first hydraulic rod 170 and the fixed frame 120. By setting a threshold, when the pressure value increases to the threshold caused by the extension of the first hydraulic rod 170, the system controls the first hydraulic rod 170 to stop running.

[0038] Regarding the structure of the second fixing mechanism 200, specifically:

[0039] The second fixing mechanism 200 includes mounting seats 210 symmetrically arranged on both sides of the base 110. Each mounting seat 210 is equipped with a frustum column 230. When the two frustum columns 230 are close to each other, they can apply pressure to the conductive rod to fix the conductive rod.

[0040] Mounting base 210 can be fixedly connected to base 110 or slidably connected to base 110. Mounting base 210 can slide on base 110 with the help of electric slider or lead screw. The frustum 230 is coaxial with the insertion hole 130. By controlling the two mounting bases 210 to move closer to each other, the frustum 230 can be inserted into the hole of the conductive rod. This allows the conductive rod to be fixed while also being driven to move to a coaxial position with the insertion hole 130.

[0041] If the conductive rod does not have a through hole in the middle, the end plane of the frustum 230 abuts against the end plane of the conductive rod, so that the conductive rod is fixed. Although it cannot drive the conductive rod to the coaxial position of the insertion hole 130, it can still effectively fix the conductive rod, so that the conductive rod cannot be displaced when drilling holes in the conductive rod later.

[0042] The frustum column 230 is made of rubber or a material with a hardness lower than that of the conductive rod, so that the conductive rod will not deform when the frustum column 230 is fixed to it.

[0043] Among the optional methods in this embodiment, the more preferred one is:

[0044] A second hydraulic rod 220 is fixedly connected to the mounting base 210, and the output end of the second hydraulic rod 220 is fixedly connected to the frustum column 230.

[0045] If the mounting base 210 is fixedly connected to the base 110, a second hydraulic rod 220 is installed on the mounting base 210. The extension and retraction of the second hydraulic rod 220 drives the frustum column 230 to move closer to or away from the conductive rod, thereby achieving a second fixation of the conductive rod.

[0046] Regarding the adjustment of the structure of mechanism 300, specifically:

[0047] The adjustment mechanism 300 includes screws 310 fixedly connected to the opposite faces of two fixed frames 120. The ends of the two screws 310 are threadedly connected to a threaded cylinder 320, and the threads of the two screws 310 are in opposite directions, so that when the threaded cylinder 320 rotates, it can drive the two fixed frames 120 to move closer or further apart.

[0048] Since the two screws 310 rotate in opposite directions and the two threaded rods are connected to a threaded cylinder 320 by the same thread, the two fixing brackets 120 can be controlled to move closer or further apart when the threaded cylinder 320 is rotated, thus adapting to drilling operations on conductive rods of different lengths. At the same time, by adjusting the position of the two fixing brackets 120, the drilling position on the conductive rod can also be avoided.

[0049] Among the optional methods in this embodiment, the more preferred one is:

[0050] A rotating base 330 is fixedly connected to the base 110, and a threaded cylinder 320 is rotatably connected to the rotating base 330.

[0051] The rotating base 330 fixes the position of the threaded cylinder 320, allowing the threaded cylinder 320 to maintain its position stability when rotating.

[0052] Among the optional methods in this embodiment, the more preferred one is:

[0053] A motor 340 is fixedly connected to the base 110. Gears 350 are fixedly connected to the output end of the motor 340 and the threaded cylinder 320. The two gears 350 mesh with each other.

[0054] When the motor 340 is started, the motor 340 can drive the threaded cylinder 320 to rotate through two meshing gears 350, and by controlling the direction of the motor 340, the direction of the threaded cylinder 320 can be changed, thereby facilitating the adjustment of the positions of the two fixed brackets 120.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
