Description

Technical Field

[0001] The invention relates to the technical field of polishing, in particular to polishing equipment for aluminum alloy automobile parts. Background Art

[0002] Auto parts, especially aluminum alloy parts, need to be polished after die-casting in order to obtain a good appearance and remove some burrs. Due to the differences in various parts and products, it is impossible to standardize mechanical polishing, and manual polishing is the main method.

[0003] In factories, aluminum alloy die-cast parts are polished using angle grinders or similar equipment equipped with felt wheels. The rapid rotation of the felt wheel causes debris from the removed parts to fly out along the tangent line of the wheel. The rotation of the felt wheel also generates airflow, which raises dust and debris. The operator's primary protective measure is a simple cotton mask, which only provides preliminary dust protection and does not completely isolate the air. This can have a significant impact on the operator's health. To address this issue, we propose a polishing device for aluminum alloy automotive parts. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6The present invention provides a technical solution: an aluminum alloy automobile parts polishing equipment, including a power body 1, the power body 1 is mainly used to drive the felt wheel 2 to rotate, and the surface of the workpiece is polished by the rotation of the felt wheel 2. The power body 1 can be electric or pneumatic. The figure shows an electric one (i.e., an angle grinder). In many factories, because there are many operating parts, pneumatic ones are mostly used from the perspective of safety. A driving component is connected through an air pipe to drive the felt wheel 2, thereby performing polishing. This embodiment is electric, and the pneumatic one is described below. The felt wheel 2 is divided into a wheel body and a felt disc, and the felt disc can be quickly replaced. The dust cover 3 is a disc-shaped structure as a whole. The difference is that the two ends of the dust cover 3 are connected to each other in a hollow shape, and it is installed on the power body 1 through one end of the small diameter. It can be directly fixed or installed in a detachable connection manner.

[0032] The dust cover 3 is mainly divided into three parts. The first part is connected to the power body 1 and the overall frame structure, namely the connecting disk 301, which is disc-shaped and slightly larger than the diameter of the felt wheel 2. The second part is the annular dust collecting ring 302. The inner diameter surface of the dust collecting ring 302 is concave toward the outer diameter side, and the diameter increases gradually from the two ends along the axial direction to the middle position. In the initial state, the two ends of the dust collecting ring 302 are respectively located at the upper and lower ends of the felt wheel 2 and exceed them. The function of the dust collecting ring 302 is to form an annular structure at the outer diameter surface of the felt wheel 2, so as to receive the workpiece when the felt wheel 2 is grinding and the workpiece is broken and flying out. The third part is the dust collecting chamber 303, which is an annular relatively closed chamber structure, located on the outer diameter side of the dust collecting ring 302;

[0033] A through groove 304 is provided between the dust collecting ring 302 and the dust collecting chamber 303. The through groove 304 is a cylindrical groove, and the axis of the through groove 304 is horizontal (i.e., located in the radial plane of the dust collecting ring 302), and the axis of the through groove 304 is arc-shaped (a plane spiral or a plane spiral arrangement). The direction of the spiral or the quasi-spiral is consistent with the rotation direction of the felt wheel 2. Whether the rotation direction of the felt wheel 2 is clockwise or counterclockwise determines whether it rotates left or right, so that the flying chips can be received by the dust collecting ring 302 and slide into the through groove 304 due to centrifugal force, and then enter the dust collecting chamber 303 through the through groove 304.

[0034] like Figure 6 As shown, a discharge port 305 is provided on the outer diameter side of the dust collecting chamber 303. The setting mode of the discharge port 305 is similar to that of the through slot 304, and the directions of the two are also consistent. The discharge port 305 can be a closed type or a direct discharge method connected to a pipe. When the felt wheel 2 is rotating for polishing, the initial power is generated because the chips fly out during the rotation. In addition, the rotation induces the rotation of the surrounding airflow. Figure 6It is a schematic diagram of the internal airflow direction of the dust cover 3 under the clockwise rotation of the felt wheel 2. The chips follow the airflow through the through slot 304 into the dust collecting chamber 303 and circulate continuously. If the discharge port 305 is in an open state, it is discharged under the action of the airflow rotation. If it is in a closed state, it is temporarily stored in the dust collecting chamber 303. The dust cover 3 is made of transparent semi-soft rubber material. Semi-soft rubber has moderate softness and can maintain the stability of its shape. It will also deform when external force is applied. Deformation is required because the surface or position to be polished is not a flat surface, so the dust cover 3 needs to be able to change adaptively. Transparency makes it easier for the operator to observe the state of the workpiece during polishing and to accurately polish it.

[0035] See Figure 6 The power body 1 of this embodiment is a pneumatic device, that is, the rotation is controlled by high-pressure gas. The air inlet 4 is set in the opposite direction to the discharge port 305, and the end of the air inlet 4 is connected to the air inlet part of the power body 1 through a pipeline. It is controlled as a whole by the controller of the power body 1, that is, when the air circuit drives the felt wheel 2 to rotate, air is synchronously introduced into the air inlet 4 for air circulation. Because the flow of high-pressure gas is stronger than the airflow driven by the rotation of the felt wheel 2, the rotation of the device generates negative pressure, thereby achieving suction through the through groove 304, so that the crushed chips can better enter the dust collecting chamber 303. When the power body 1 stops working, the air circuit is disconnected and the airflow of the air inlet 4 also stops, and is controlled uniformly.

[0036] See Figure 6 The closer the outer ends of the center lines of the air inlet 4 and the discharge port 305 are, the better, and they are not close in opposite directions, that is, the two are in an eight-shaped shape from the radial direction of the dust cover 3 to the inside, rather than an inverted eight-shaped shape, because the closer the two are, the closer the air inlet 4 and the discharge port 305 are to a complete circle, which is convenient for better discharge. If it is an inverted eight-shaped shape, the airflow is more likely to enter from the air inlet 4 and then be discharged directly from the discharge port 305, which is not conducive to driving all the crushed chips to circulate and discharge.

[0037] See Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 , different from the closed dust collecting chamber 303, the dust collecting chamber 303 of this embodiment is configured as a semi-open ring, that is, the dust collecting chamber 303 is a semi-ring body that is concave inwardly and radially outwardly along the dust cover 3, and the lower end edge of the dust collecting chamber 303 is fixedly connected or integrated with the lower end edge of the dust collecting ring 302, and the upper end edge of the dust collecting chamber 303 extends to the upper surface of the connecting disk 301;

[0038] The upper edge of the dust collecting chamber 303 can be gradually reduced as the thickness is extended to provide better flexibility. The annular protrusion 5 is fixedly provided on the connecting plate 301, and the corresponding dust collecting chamber 303 has a concave structure adapted to the annular protrusion 5. Due to the structural material, the concave structure on the dust collecting chamber 303 can be snapped in and out.

[0039] Furthermore, the edge of the upper end of the dust collecting chamber 303 is set to be in an upward warped state, so that when the user opens it, it is convenient to buckle the upper end of the dust collecting chamber 303 and then pull it diagonally upward to open it. The purpose of setting it to be openable is to facilitate the problem of debris blockage in the dust cover 3. The open state is convenient for cleaning. The advantage of using the semi-open loop of the dust collecting chamber 303 as a substitute for the discharge port 305 is that the discharge port 305 does not need to be connected to a pipe and is not constrained when in use. Otherwise, due to the two pipes of air intake and discharge, there will be a certain degree of inconvenience during use. Quantitative cleaning can be carried out when a certain amount of debris is collected in the dust collecting chamber 303.

[0040] Different from the previous embodiment, the semi-open loop of the dust collecting chamber 303 and the discharge port 305 of this embodiment are both provided at the same time, which can be used selectively and is also convenient for cleaning the blockage problem.

[0041] See Figure 3 、 Figure 5 and Figure 6 Compared with the use of semi-soft rubber material, the use of film can make the overall weight of the dust cover 3 lighter, and because the semi-soft rubber material is easy to be stained with dust, while the film is not easy to be stained with dust after being propped up, it is more conducive to collection and discharge. The figure shows a double-layer structure, and a connection is set at the interval between the two layers to form a frame, which is then inflated to form. The principle is similar to the air column bag in express packaging;

[0042] Furthermore, for better use, it is preferably set to a multi-layer structure with at least three layers, the middle layer is a gas-filled structural layer, and a thin film is set on the two surfaces of the middle layer respectively. The films of the two surface layers are mainly used to form a smooth surface without producing steps or grooves, so that the gas can better drive the circulation of the crushed chips.

[0043] See Figure 7 An extension pipe 6 is provided at the end of the air inlet 4. The function of the extension pipe 6 is to form a buffer stage. At the moment of starting the power body 1, high-pressure gas rushes in rapidly. If there is no buffer stage, the through slot 304 near the air inlet 4 will spray out debris in the reverse direction. Therefore, an extension pipe 6 is provided to balance the initial airflow and stabilize it before entering the dust collection chamber 303.

[0044] Preferably, the extension tube 6 extends at least half a circumference, and should not be too long, preferably half a circumference to a circumference.

[0045] See Figure 5 The semi-open groove 3021 is opened at the lower end position of the inner surface of the dust collecting ring 302. Its function is that when the air is stopped, there are still fragments that have not entered the through groove 304 or the dust collecting chamber 303 and are on the surface of the dust collecting ring 302. After the air is stopped (the felt wheel 2 stops rotating), the fragments fall on the inner surface of the dust collecting ring 302 and slide downward. In order to avoid separation, the semi-open groove 3021 is set to receive them, and they will enter the dust collecting chamber 303 again with the air flow when started next time.

[0046] See Figure 8 A locking plate 7 is provided on the power body 1. The outer edge of the locking plate 7 adopts a wave-type joint structure. The inner surface of the upper end of the dust cover 3 is adaptively set, and then a detachable installation is achieved by external locking (clamp, etc.).
