Description

Technical Field

[0001] This application belongs to the field of power distribution cabinet manufacturing technology, and in particular relates to an auxiliary tooling for polishing copper busbars. Background Technology

[0002] Copper busbars play a vital role in electrical distribution cabinets, serving as the core component for high-current conductors. The main processes for manufacturing copper busbars include cutting, grinding, drilling, and bending. Among these, the grinding process primarily removes the burrs formed at both ends of the cut copper busbar to facilitate installation and prevent issues such as tip discharge and localized overheating.

[0003] The current polishing method mainly involves manually pressing down the copper busbar and using an angle grinder to polish both ends of the copper busbar. This polishing method is inconvenient and slow, which is not conducive to improving the production efficiency of the distribution cabinet. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides an auxiliary tooling for polishing copper busbars, which can effectively improve the polishing efficiency of copper busbars.

[0005] To achieve the above objectives, the present invention employs the following technology: An auxiliary tooling for polishing copper busbars includes: The substrate is set horizontally. The support frame is horizontally mounted above the substrate; The rotating frame has rotating shafts connected to the middle of the outer sides at both ends, and is oriented towards the length of the rotating frame; the two rotating shafts are respectively inserted through both ends of the support frame and are rotatable around their own axes; The clamping part includes multiple placement plates arranged in an array along the length of the rotating frame on one side, facing the length of the rotating frame; when the rotating frame is in a horizontal state, the placement plates are arranged vertically; a strip plate is provided on the other side of the rotating frame, facing the length of the rotating frame and movable along the width of the rotating frame, for cooperating with the placement plates to clamp the copper busbar. The locking mechanism, located at both ends of the support frame, is used to position and fix the rotating frame in a horizontal position; The support plate is horizontally positioned below the rotating frame and oriented towards the length of the rotating frame. Its top surface has a vertically arranged strip groove along the length of the rotating frame, and the support plate is movable in the vertical direction.

[0006] The beneficial effects of this utility model are as follows: 1. By setting up a support plate and cooperating with the vertical plate and the inclined plate, the strip plate and the placement plate can be separated to form a space for vertically placing the copper busbar, which simplifies the installation process of the copper busbar; 2. By inserting the copper busbar into the strip groove, the copper busbar can be positioned vertically and attached to the placement plate, ensuring that the strip plate and placement plate can stably clamp the copper busbar when the support plate moves down, so that the operator can polish the copper busbar and improve the practicality of the tooling. 3. The tooling can install multiple copper busbars at one time for grinding operations, which has high grinding efficiency and helps to improve the production efficiency of the distribution cabinet.

Detailed Implementation

[0012] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0013] This application provides an auxiliary tooling for polishing copper busbars, such as... Figures 1-4 As shown, it includes: a base plate 1, a support frame 2, a rotating frame 3, a clamping part 4, a locking mechanism 5, a support plate 6, etc.

[0014] Among them, such as Figures 1-3 As shown, the substrate 1 is horizontally arranged with four columns 12 on it; the support frame 2 is rectangular and horizontally mounted above the substrate 1, with the four columns 12 connected to the four corners of the support frame 2 respectively; the rotating frame 3 is rectangular, with rotating shafts 31 connected to the middle of the outer sides of both ends of the frame 3 and oriented towards the length of the rotating frame 3. The two rotating shafts 31 are coaxial and pass through the middle of both ends of the support frame 2 respectively, extending to the outer sides of both ends of the support frame 2. The two rotating shafts 31 are rotatable around their own axes.

[0015] like Figures 1-4 As shown, the clamping part 4 includes five mounting rods 43 arranged in an array along the length of the rotating frame 3 on one side. Each mounting rod 43 faces the width of the rotating frame 3, and its end is connected to a placement plate 41. Each placement plate 41 faces the length of the rotating frame 3. When the rotating frame 3 is in a horizontal state, the placement plate 41 is arranged vertically. At the other end of the rotating frame 3, there are five guide posts 44 arranged in an array along the length. The guide posts 44 face the width of the rotating frame 3, and each guide post 44 is connected to a corresponding mounting rod. 43 is coaxially arranged, the end face of the guide post 44 is coaxial and slides through the top rod 45, the end of the top rod 45 is vertically connected to the strip plate 42, and a spring 46 is sleeved on the top rod 45. The spring 46 is connected to the end face of the strip plate 42 and the guide post 44. When the spring 46 is in its natural state, the distance between the strip plate 42 and the placement plate 41 is less than the thickness of the copper busbar. A sloping plate 47 is formed on one side of the strip plate 42. When the rotating frame 3 is in a horizontal state and one side of the strip plate 42 is vertically downward, the sloping plate 47 is arranged facing downward on the other side of the rotating frame 3.

[0016] like Figures 1-3 As shown, the locking mechanism 5 is located at both ends of the support frame 2, and is used to position and fix the rotating frame 3 in a horizontal state; the support plate 6 is horizontally located below the rotating frame 3 and is arranged in the length direction of the rotating frame 3. The top surface of the support plate 6 has a vertically arranged strip groove 61 along the length direction of the rotating frame 3. The width of the strip groove 61 is the same as the thickness of the copper busbar. One side of the strip groove 61 is coplanar with the side of the placement plate 41 facing the strip plate 42. The support plate 6 is moved in the vertical direction; a vertical plate 62 is provided on one side of the support plate 6 along its length direction. The top corner of the vertical plate 62 is rounded and is used to abut against the inclined plate 47.

[0017] When applying, such as Figures 1-4As shown, before installing the copper busbar, the locking mechanism 5 is operated to fix the rotating frame 3 in a horizontal state, the bearing plate 6 moves upward, and the top of the vertical plate 62 abuts against the bottom of the inclined plate 47. As the bearing plate 6 continues to move upward, the top of the vertical plate 62 will abut against the inclined plate 47 and move upward along the inclined surface of the inclined plate 47. The vertical plate 62 gives the inclined plate 47 a horizontal component force, so that the strip plate 42 separates from the placement plate 41 until the bearing plate 6 moves up to a predetermined distance from the rotating frame 3. The distance between the strip plate 42 and the placement plate 41 is greater than the thickness of the copper busbar. The operator vertically inserts the copper busbar between each placement plate 41 and the strip plate 42 and inserts the lower end of the copper busbar into the strip groove 61 of the bearing plate 6. At this time, each copper busbar is arranged vertically and arrayed along the length direction of the bearing plate 6, and one side of each copper busbar is in contact with the corresponding placement plate 41. After the copper busbars are installed, the support plate 6 carries them downwards. Once the vertical plate 62 and the inclined plate 47 are completely separated, the strip plate 42, under the action of the spring 46, presses the copper busbars firmly onto the placement plate 41, thus completing the fixation of the copper busbars. The operator uses an angle grinder to grind one end of each of the five copper busbars to remove burrs. Then, the locking mechanism 5 is operated to release the rotating frame 3, and the rotating frame 3 is rotated 180 degrees so that the other end of the copper busbar is vertically upward. The locking mechanism 5 is then operated to fix the rotating frame 3 again, and the operator grinds the other end of the copper busbars. After all the copper busbars are completely ground, the support plate 6 moves upwards. Through the cooperation of the vertical plate 62 and the inclined plate 47, the strip plate 42 is separated from the placement plate 41. At this point, the ground copper busbars can be removed, and the next batch of copper busbars to be ground can be installed.

[0018] When installing copper busbars, the support plate 6 moves upward, and the strip plate 42 and the placement plate 41 can be separated through the cooperation of the vertical plate 62 and the inclined plate 47 to form a space for vertically placing the copper busbars, simplifying the installation process. At the same time, by inserting the copper busbars into the strip groove 61, the copper busbars can be positioned vertically and attached to the placement plate 41, ensuring that when the support plate 6 moves downward, the strip plate 42 and the placement plate 41 can stably clamp the copper busbars, making it easier for operators to polish the copper busbars and improving the practicality of the fixture. The fixture can install multiple copper busbars at once for polishing operations, with high polishing efficiency, which is beneficial to improving the production efficiency of the distribution cabinet.

[0019] Specifically, such as Figure 1 As shown, the locking mechanism 5 includes two pairs of locking blocks 51 located on the outer sides of both ends of the support frame 2. In each pair, two locking blocks 51 are located on both sides of the corresponding rotating shaft 31. Locking holes are provided on both pairs of locking blocks 51 along the width direction of the support frame 2. Shaft holes are provided on both rotating shafts 31 perpendicular to their axes. The locking holes and shaft holes are used to insert pins 52. In application, when the rotating shafts 31 at both ends of the rotating frame 3 are manually rotated, and the rotating frame 3 is rotated to the horizontal position, the shaft holes on the rotating shafts 31 at both ends are coaxial with the locking holes on the corresponding pair of locking blocks 51. At this time, the two pins 52 are inserted into the locking holes and shaft holes at both ends of the support frame 2, respectively, to fix the rotating frame 3.

[0020] Specifically, such as Figure 1 and Figure 2 As shown, a linear mechanism 11 is provided on the substrate 1, with its driving end facing vertically and connected to the bottom of the support plate 6. The linear mechanism 11 can be in the form of a linear cylinder, hydraulic cylinder, etc.

[0021] Preferred, such as Figure 1 As shown, in order to improve the stability of the operation of the support plate 6, a guide structure can be provided between the two ends of the support plate 6 and the base plate 1.

[0022] Preferred, such as Figure 3 and Figure 4 As shown, vertically positioned limiting plates 48 can be set at both ends of the placement plate 41. The two limiting plates 48 are arranged along the width direction of the placement plate 41, and the distance between the two limiting plates 48 is equal to the width of the copper busbar. This can prevent the copper busbar from tilting towards both ends of the placement plate 48 when it is installed.

[0023] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
