Description

Technical Field

[0001] This invention belongs to the technical field of busbar trunking production equipment, specifically relating to a busbar trunking opening device. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects. The manufacturing process of busbar trunking requires cutting, welding, and drilling holes in the sheet metal.

[0003] Existing busbar trunking drilling devices use lasers to drill holes in placed busbar trunking plates to meet the production requirements of busbar trunking. During the drilling process, the device cannot secure the busbar trunking plates. Due to vibrations during operation, the busbar trunking plates may shift out of the hole position, resulting in drilling errors. This cannot guarantee the accuracy of drilling the busbar trunking plates, leading to an increased defect rate and higher production costs. Summary of the Invention

[0004] This invention provides a busbar trunking hole-opening device, which aims to solve the problem that existing busbar trunking hole-opening devices cannot secure the busbar trunking material. Due to vibration during operation, the busbar trunking material may move out of the hole position, resulting in hole-opening errors. This cannot guarantee the accuracy of the busbar trunking material hole-opening, thus increasing the defect rate and production costs.

[0011] Furthermore, the longitudinal movement module includes an electric slide rail fixed to the lower end of the slide plate, an electric slider slidably connected to the electric slide rail, and the electric slider is connected to the upper end of the laser head.

[0012] Furthermore, both ends of the fastening plate one are provided with assembly openings, the inside of the assembly openings is fixedly connected to the assembly column, the outer surface of the assembly column is clamped to the fastening plate two, and the side of the movable rod near the assembly column is fixedly connected to the fastening plate one.

[0013] Furthermore, a spiral beryllium copper wire II is installed between the connecting platform and the inner column, which can pull the inner column back to its original position. A spiral beryllium copper wire III is installed between the assembly column and the fastening plate II. A slope is installed at one end of the pressing platform near the track.

[0014] Furthermore, the anti-arching unit also includes a spiral beryllium copper wire, a constraint plate, and a rectangular opening. The spiral beryllium copper wire is installed between the bearing column and the pressure block. The constraint plate is fixed to the upper end of the bearing column, and the rectangular opening is reserved on the pressure block.

[0015] Furthermore, a protrusion is fixedly connected to the lower wall of the constraint piece, the bending strip touches the track, and the protrusion touches the upper wall of the pressure block.

[0017] Furthermore, a disassembly port is reserved at the lower end of the outer surface of the second outer cylinder.

[0018] Furthermore, the outer cylinder one is filled with hydraulic transmission oil, the outer cylinder two is filled with hydraulic transmission oil, and a coil spring is installed between the support two and the stop post. One end of the coil spring is installed on the inner surface of the support two, and the other end is installed on the wall surface of the stop post.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The present invention can fasten the busbar trunking plate by installing the plate fastening module, avoiding the vibration caused during the opening of the hole and preventing errors in the opening, thus ensuring the accuracy of the opening of the busbar trunking plate, reducing the defect rate of production, and also reducing production costs.

[0021] 2. This invention, through the movement of the second fastening plate towards the busbar plate and its contact with the busbar plate, applies pressure to the busbar plate, allowing the second fastening plate to perform fastening and correction of the busbar plate's displacement during fastening. This helps to correct the displacement of the busbar plate during fastening, thereby ensuring the accuracy of the busbar plate during fastening and guaranteeing the pass rate of the perforated busbar plate. Furthermore, the downward movement of the protective platform and its contact with the inner surface of the constraint opening prevent the track and inner column from moving further. The inability of the inner column to move further prevents the moving end of the connecting platform and hydraulic cylinder from moving further, thus preventing excessive pressure intensity during fastening. This reduces the pressure intensity borne by the busbar plate wall. Excessive pressure can cause changes in the shape of the busbar plate and cause slight displacement or displacement of the busbar plate. By maintaining a moderate pressure intensity, the position of the busbar plate can be kept constant during drilling.

[0022] 3. In this invention, the bending strip moves downwards, pulling the pressing block downwards. The pressing block moves downwards and contacts the upper wall of the busbar trough plate, applying pressure to prevent the busbar trough plate from arching. The downward pressure of the pressing block stabilizes the position of the busbar trough plate, preventing arching during the opening process and ensuring the accuracy of the opening. Furthermore, the shaking of the pressing block pulls the bearing column to shake, which in turn pulls the fastening plates to shake, shaking off waste material from the fastening plate wall and ensuring the cleanliness of the busbar trough plate wall.

[0023] 4. In this invention, the support two moves downward to pull the stop column downward. The stop column moves downward to the stop opening, constraining the movable rod. Under the constraint of the stop column, the movable rod cannot move laterally. The inability of the movable rod to move laterally also prevents the fastening plate one from moving laterally and thus constrains it. The constrained fastening plate one can prevent the fastening plate one from being loosened from the busbar plate due to human error. Even slight movement of the fastening plate one will reduce the accuracy of the opening of the busbar plate. By constraining the fastening plate one, such a situation can be avoided, ensuring the accuracy of the opening of the busbar plate.

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Reference Figures 1-11This invention provides a busbar trunking opening device, comprising a first bracket 1, a second bracket 2 fixedly connected to the upper end of the first bracket 1, a transverse moving module 3 mounted on the upper end of the second bracket 2, a longitudinal moving module 4 mounted on the transverse moving module 3, a welding machine housing 5 mounted on the top of the second bracket 2, a laser head 6 mounted on the lower end of the longitudinal moving module 4, the welding machine housing 5 being connected to the laser head 6, and a plate fastening module 7 mounted on the upper end of the first bracket 1 and below the laser head 6.

[0040] The busbar plate is fastened by the plate fastening module 7. The horizontal moving module 3 and the vertical moving module 4 pull the laser head 6 to move it to the opening on the busbar plate. The laser head 6 emits a laser to open the busbar plate, realizing automatic and precise opening of the busbar plate.

[0041] Reference Figure 2 The transverse module 3 includes a pair of supports 31 fixed to the bracket 2. A lead screw 32 is rotatably connected between the two supports 31. A sliding plate 33 is threaded onto the lead screw 32. The two ends of the sliding plate 33 are slidably connected to the side plate on the bracket 2. A motor 34 is fixedly connected to the outside of one of the supports 31. The output end of the motor 34 is connected to one end of the lead screw 32. When it is necessary to adjust the position of the laser head 6, the motor 34 rotates, driving the lead screw 32 to rotate. The lead screw 32 drives the sliding plate 33 to move, thereby adjusting the position of the laser head 6.

[0042] Reference Figure 1 and Figure 2 The longitudinal movement module 4 includes an electric slide rail 41 fixed to the lower end of the slide plate 33. An electric slider 42 is slidably connected to the electric slide rail 41. The electric slider 42 is connected to the upper end of the laser head 6. When the position of the laser head 6 needs to be adjusted, the electric slider 42 slides on the electric slide rail 41, thereby driving the laser head 6 to move and realize the adjustment of the position of the laser head 6.

[0043] Reference Figures 3-11 The plate fastening module 7 includes a worktable 71 fixed to the bracket 1, and also includes a stop unit, an anti-arching unit and a restraint unit.

[0044] Among them, the upper end of the workbench 71 is fixedly connected to the hydraulic cylinder 72, the side of the hydraulic cylinder 72 is fixedly connected to the rectangular tube 715, the inside of the rectangular tube 715 is movably installed with the movable rod 716, and the movable end of the hydraulic cylinder 72 is fixedly connected to the fastening plate 73.

[0045] The stop unit includes a channel 74, a pressing table 75, a connecting table 76, an inner column 77, a constraint port 711, a track 712, and a protective table 7121. The channel 74 is reserved on the upper wall of the fastening plate 73. The pressing table 75 is movably installed at the lower end inside the channel 74. The movable end of the hydraulic cylinder 72 is reserved with a through port 7122. The connecting table 76 is fixed to the inner surface of the through port 7122. The inner column 77 can move through the connecting table 76. The constraint port 711 is reserved on the upper surface of the worktable 71. The track 712 is fixed to the side of the inner column 77 near the worktable 71. The protective table 7121 can move through the lower end of the track 712.

[0046] The anti-arching unit includes a bearing column 7131, a pressure block 7132, and a bending strip 7133. The bearing column 7131 is fixed to the upper wall of the fastening plate 73. The pressure block 7132 is movably installed on the outer wall of the bearing column 7131. The bending strip 7133 is fixed to the lower wall of the pressure block 7132. The restraint unit includes an outer cylinder 7141, a rubber block 7142, and a movable column 7143. The outer cylinder 7141 is fixed to the side of the fastening plate 73 near the hydraulic cylinder 72. The rubber block 7142 is movably installed inside the outer cylinder 7141. The movable column 7143 is fixed to the upper wall of the rubber block 7142. Excessive pressure on the busbar plate causes a slight change in the orientation of the busbar plate. Maintaining a moderate pressure ensures that the orientation of the busbar plate remains constant during drilling.

[0047] Both ends of the fastening plate 73 have pre-drilled assembly openings 78. The assembly post 79 is fixedly connected to the inside of the assembly opening 78. The outer surface of the assembly post 79 is clamped to the fastening plate 710. The movable rod 716 is fixedly connected to the fastening plate 73 near the assembly post 79. The fastening plate 710 can help correct the displacement of the busbar plate during fastening, thereby ensuring the accuracy of the busbar plate during fastening.

[0048] A spiral beryllium copper wire II is installed between the connecting platform 76 and the inner column 77. The inner column 77 can be pulled back to its original position via the spiral beryllium copper wire II. A spiral beryllium copper wire III is installed between the assembly column 79 and the fastening plate II 710. The fastening plate II 710 can be pulled back to its original position via the spiral beryllium copper wire III. A slope is installed at the end of the pressing platform 75 that is close to the track 712.

[0049] During use, the busbar trunking plate is placed on the upper surface of the workbench 71. The hydraulic cylinder 72 pulls the fastening plate 2 710 to move towards the side closest to the busbar trunking plate. The fastening plate 2 710 moves towards the position closest to the busbar trunking plate and contacts and applies pressure to the busbar trunking plate. The fastening plate 2 710 also bears the reverse force of the pressure on the busbar trunking plate and moves towards the pressure table 75. The movement of the fastening plate 2 710 towards the pressure table 75 applies pressure to the spiral beryllium copper wire 3. The spiral beryllium copper wire 3 is compressed under the pressure of the fastening plate 2 710. The spiral beryllium copper wire 3 presses against the fastening plate 2 710, causing the fastening plate 2 710 to stop and correct the position of the busbar trunking plate. Simultaneously, the fastening plate 1 73 moves towards the position closest to the busbar trunking plate. The movement of the fastening plate 1 73 towards the position closest to the busbar trunking plate pulls the pressure table 75 to move, pressing... The pressing platform 75 moves and contacts the busbar plate, applying pressure to the busbar plate. The pressing platform 75, bearing the reverse force of the pressure on the busbar plate, moves towards the hydraulic cylinder 72. The pressing platform 75 moves towards the hydraulic cylinder 72 and contacts the track 712, applying pressure to the track 712. The track 712, under the pressure of the pressing platform 75, moves downward. The downward movement of the track 712 pulls the inner column 77 downward. The downward movement of the inner column 77 applies pressure to the spiral beryllium copper wire II. The spiral beryllium copper wire II shortens under the pressure of the inner column 77. The downward movement of the track 712 pulls the protective platform 7121 downward. The downward movement of the protective platform 7121 contacts the inner surface of the restraint port 711, preventing the track 712 and the inner column 77 from moving further. The inability of the inner column 77 to move further prevents the movement of the connecting platform 76 and the hydraulic cylinder 72 from continuing.

[0050] Reference Figures 3-11 The anti-arching unit also includes a spiral beryllium copper wire 7134, a constraint piece 7135, and a rectangular opening 7137. The spiral beryllium copper wire 7134 is installed between the bearing column 7131 and the pressure block 7132. The constraint piece 7135 is fixed to the upper end of the bearing column 7131. The rectangular opening 7137 is reserved on the pressure block 7132. By pressing the busbar trunking plate downwards through the pressure block 7132, the position of the busbar trunking plate can be stabilized, so as to prevent the busbar trunking plate from arching due to external forces.

[0051] The protrusion 7136 is fixed to the lower wall of the constraint plate 7135. The bending strip 7133 and the track 712 are in contact. The protrusion 7136 and the upper wall of the pressure block 7132 are in contact. The bearing column 7131 shakes and pulls the fastening plate 73 to shake together, shaking off the waste on the fastening plate 73, which can ensure the cleanliness of the busbar plate.

[0052] The constraint unit also includes an outer cylinder 7144, a rubber block 7145, a support 7146, a stop post 7147, and a stop opening 7149. The outer cylinder 7144 is fixed to the upper end of the rectangular cylinder 715. The rubber block 7145 is movably installed inside the outer cylinder 7144. The support 7146 is fixed to the lower wall of the rubber block 7145. The stop post 7147 is screwed onto the support 7146. The stop opening 7149 is reserved on the outer wall of the movable rod 716. Even slight movement of the fastening plate 73 can reduce the accuracy of the opening of the busbar trunking plate. By constraining the fastening plate 73, such situations can be avoided, reducing the defect rate of the opening of the busbar trunking plate.

[0053] The lower end of the outer surface of the second outer cylinder 7144 has a disassembly port 7148. The first outer cylinder 7141 is connected to the inside of the second outer cylinder 7144 through a channel. A spiral beryllium copper wire 4 is installed between the first rubber block 7142 and the first outer cylinder 7141. One end of the spiral beryllium copper wire 4 is installed at the lower end of the inside of the first outer cylinder 7141, and the other end is installed at the lower end of the first rubber block 7142. The spiral beryllium copper wire 4 can pull the first rubber block 7142 back to its original position.

[0054] The outer cylinder 7141 is filled with hydraulic transmission oil, and the outer cylinder 7144 is also filled with hydraulic transmission oil. A coil spring is installed between the support 7146 and the stop post 7147. One end of the coil spring is installed on the inner surface of the support 7146, and the other end is installed on the wall of the stop post 7147. The coil spring can pull the stop post 7147 back to its original position.

[0055] During use, the track 712 moves downward under the pressure of the pressure table 75. As the track 712 moves downward, it contacts and presses against the bending strip 7133. The bending strip 7133, under the pressure of the track 712, moves downward, pulling the pressure block 7132 downward. The pressure block 7132 moves downward and contacts the upper surface of the busbar trough plate, pressing against it to prevent the busbar trough plate from arching. Furthermore, as the pressure block 7132 moves downward, it presses against the spiral beryllium copper wire. The spiral beryllium copper wire four is compressed and shortened by the pressure block 7132. With the cooperation of the spiral beryllium copper wire two, the track 712 moves upward and returns to its original position, away from the contact of the bending strip 7133. The movement of the bending strip 7133 away from the contact of the track 712 causes the pressure block 7132 to move upward and return to its original position with the cooperation of the spiral beryllium copper wire four. The upward movement of the pressure block 7132 back to its original position knocks on the protrusion 7136 and causes it to vibrate. The vibration of the pressure block 7132 pulls the bearing column 7131 to vibrate, and the vibration of the bearing column 7131 pulls the fastening piece 73 to vibrate together.

[0056] The bending strip 7133 moves downwards, pulling the compression block 7132 downwards. The compression block 7132 moves downwards and contacts the movable column 7143, applying pressure to the movable column 7143. The movable column 7143, under the pressure of the compression block 7132, moves downwards, pulling the rubber block 7142 downwards. The rubber block 7142, moving downwards, applies pressure to the hydraulic transmission oil inside the outer cylinder 7141. The hydraulic transmission oil inside the outer cylinder 7141, under the pressure of the rubber block 7142, flows into the outer cylinder 7144. The hydraulic transmission oil flowing into the outer cylinder 7144 applies pressure to the rubber block 7145. Rubber block 7145 moves downwards under the pressure of the hydraulic transmission oil flowing into outer cylinder 7144. Rubber block 7145 moves downwards, traction support 7146 moves downwards, support 7146 moves downwards, traction stop 7147 moves downwards, and stop 7147 moves downwards into stop port 7149. Stop 7147 constrains movable rod 716. Movable rod 716 cannot move laterally under the constraint of stop 7147. Movable rod 716 cannot move laterally, which prevents fastening plate 73 from moving laterally. After the busbar plate is opened, stop 7147 is manually rotated to move away from stop port 7149 and release the constraint on movable rod 716.
