[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0030] like Figure 1 As shown, an aluminum alloy conductive rod surface grinding and polishing device includes a processing table 1, a grinding and polishing mechanism on the processing table 1, two first synchronous wheels fixedly mounted on the grinding and polishing mechanism, a mounting plate 2, a rotating roller 3, a second synchronous wheel 4, a belt 5, an electric chuck 6, a telescopic component 7, a mounting shell 8, a connecting roller 9, a gear transmission assembly 10, a clamping assembly, and an insert roller 11.

[0031] Two mounting plates 2 are fixed on the processing table 1, and a rotating roller 3 is rotatably connected inside each of the two mounting plates 2;

[0032] The second synchronous pulley 4 is fixed on the rotating roller 3 and connected to the first synchronous pulley via the belt 5;

[0033] The electric chuck 6 is fixedly connected to one end of a rotating roller 3;

[0034] The telescopic component 7 is fixedly connected to one end of another rotating roller 3;

[0035] The hollow mounting shell 8 is connected to a telescopic component 7, and a connecting roller 9 is rotatably connected inside the mounting shell 8, as well as a gear transmission assembly 10 connected to the connecting roller 9 (specifically, a side door is rotatably connected to the mounting shell 8, which is not shown in the figure, and the components inside the mounting shell 8 can be maintained through the side door).

[0036] The clamping components are symmetrically fixed at both ends of the connecting roller 9;

[0037] The insertion roller 11 is rotatably connected to the mounting housing 8, and the center of the insertion roller 11 is on the same straight line as the center of the electric chuck 6.

[0038] Further refinements of the embodiments of this utility model, such as... Figure 2As shown, the clamping assembly includes a fixed plate 12, an auxiliary telescopic component 13, and an arc-shaped clamping plate 14. The two ends of the connecting roller 9 are symmetrically fixed with fixed plates 12. The fixed plate 12 is fixed with an auxiliary telescopic component 13. The auxiliary telescopic component 13 is connected to an arc-shaped clamping plate 14 that is in contact with the surface of the aluminum alloy conductive rod.

[0039] In a further optimization of the above embodiment, the surfaces of the arc-shaped clamping plate 14 and the insertion roller 11 are both provided with a rubber layer. The rubber layer is not labeled in the figure. The rubber layer can reduce the wear of the aluminum alloy conductive rod during clamping and insertion.

[0040] Further refinements of the embodiments of this utility model, such as... Figure 2 As shown, a debris collection box 15 is placed on the processing table 1 to collect most of the debris that falls off during the grinding and polishing process.

[0041] It should be noted that the grinding and polishing mechanism, electric chuck 6, telescopic component 7, gear transmission assembly 10, and auxiliary telescopic component 13 are all electrically connected to the controller, which is not labeled in the figure.

[0042] The working process of this utility model:

[0043] The initial grinding and polishing mechanism does not work. Then, the electric chuck 6 firmly clamps and limits one end of the aluminum alloy conductive rod. Then, the controller controls the movement of the telescopic component 7, which in turn drives the insertion roller 11 to move horizontally a predetermined distance so that the insertion roller 11 is inserted into the inner hole of the aluminum alloy conductive rod from one side (the inner hole has been pre-processed and is a structure inherent in the conductive rod itself). The end of the aluminum alloy conductive rod is spaced apart from the mounting shell 8.

[0044] After the insertion roller 11 is engaged with the inner hole of the aluminum alloy conductive rod, the grinding and polishing mechanism is controlled by the controller. The operating principle and structural composition of the grinding and polishing mechanism are fully disclosed in the announcement number CN219075267U, which proposes a conductive rod grinding and polishing device. It belongs to the prior art and will not be described in detail. Then, the aluminum alloy conductive rod can be driven to rotate while the grinding and polishing process of the aluminum alloy conductive rod surface is carried out.

[0045] As the grinding process continues, the remaining area, excluding the area held by the electric chuck 6, can be effectively ground and polished. Once the grinding and polishing of the remaining area is completed, the grinding and polishing assembly stops. Then, the gear transmission assembly 10 is operated by the controller (the gear transmission assembly 10 includes a servo motor, a main gear, and a secondary gear, with the secondary gear fixed on the connecting roller 9 and meshing with the main gear). This allows the two sets of clamping assemblies to rotate along the connecting roller 9 at a pre-set fixed angle. After rotation, the two sets of clamping assemblies are aligned with the end of the aluminum alloy conductive rod. The controller then controls the operation of the clamping assemblies to securely clamp the end area of ​​the aluminum alloy conductive rod. After clamping, the controller first controls the electric chuck 6 to release the lock on the initial end of the aluminum alloy conductive rod. Then, the telescopic component 7 drives the aluminum alloy conductive rod to move horizontally to the right. Once the initial end of the aluminum alloy conductive rod is away from the electric chuck 6, the grinding and polishing mechanism restarts to process the previously obscured and un-ground parts, thus completing the effective grinding and polishing of the surface of the aluminum alloy conductive rod.

[0046] After the final processing is completed, the clamping component is first controlled by the controller to move away from the end of the aluminum alloy conductive rod. Then, the aluminum alloy conductive rod is manually pulled out from the insertion roller 11 to complete the unloading. Then, a new round of aluminum alloy conductive rod grinding and polishing process can begin.

[0047] Compared to existing technologies, this device can automatically perform a grinding and polishing process on aluminum alloy conductive rods to remove the aluminum oxide layer and mechanical scratches on their surface. At the same time, during the first round of grinding and polishing, it can process areas other than the clamping area of ​​the electric chuck 6. After processing, it can automatically transfer the position of the aluminum alloy conductive rod to process the previously blocked areas, thus avoiding areas that cannot be processed and improving the grinding and polishing effect of the aluminum alloy conductive rod.

[0048] It should be noted that the principle by which the two sets of clamping assemblies rotate at a fixed angle along the connecting roller 9 through the gear transmission assembly 10 is as follows:

[0049] 1. The servo motor has high-precision position feedback and closed-loop control capabilities, which can accurately control the rotation angle of the output shaft (±0.1° to ±1°); the number of motor rotation steps is controlled by pulse signals, which directly determines the discretization accuracy of the output angle.

[0050] 2. The gear ratio (i = Z1 / Z2) converts the minute angular changes of the servo motor into the target angle of the connecting roller 9.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
