Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile processing technology, and in particular to an automatic sandblasting machine for aluminum alloy profiles. Background Technology

[0002] Sandblasting is a surface treatment process for workpieces. It uses compressed air to create a high-speed jet of abrasive material that is propelled at high speed onto the surface of the workpiece, resulting in a certain degree of cleanliness and varying roughness, thus improving the mechanical properties of the workpiece surface. However, existing sandblasting equipment often results in uneven sandblasting of aluminum alloy surfaces.

[0003] Existing patent CN217620001U describes a sandblasting device for aluminum alloy profiles. Through the cooperation between the motor and the transmission shaft, the driving gears on both sides can be rotated. Through the cooperation between the driving gear and the driven gear, the left and right rotating shafts can be rotated simultaneously. Through the cooperation between the movable column, the right rotating shaft, the limiting hole, and the limiting rod, the two limiting plates can be rotated. This allows the aluminum alloy profile fixed between the two limiting plates to rotate, thus facilitating uniform sandblasting of the outer surface of the aluminum alloy profile.

[0004] However, in the process of using an existing patented aluminum alloy profile sandblasting device, the device uses the elastic drive of a reset spring to fix the aluminum alloy profile with a limiting plate. However, the driving force of the reset spring will change, which makes it easy for the aluminum alloy profile to detach from the limiting plate during rotation, thus affecting the sandblasting process. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic sandblasting machine for aluminum alloy profiles, which solves the problem that the aforementioned device uses the elastic drive of a return spring to fix the aluminum alloy profile with a limiting plate. However, the driving force of the return spring changes, which makes the aluminum alloy profile easy to detach from the limiting plate during rotation, thus affecting the sandblasting process.

[0006] To achieve the above objectives, this utility model provides an automatic sandblasting machine for aluminum alloy profiles, including a base plate, a mounting frame, a sandblasting seat, and a receiving device. The mounting frame is fixedly mounted on the base plate, and the sandblasting seat is fixedly mounted on the mounting frame. The sandblasting seat has spray holes and a sand inlet pipe connected to it. The receiving device is mounted on the base plate. The machine also includes a fixing device, which comprises a contact plate, a rotating shaft, a rotating disc, a moving cylinder, a guide rod, a moving assembly, and a support assembly. The rotating shaft is rotatably mounted on the mounting frame, the contact plate is fixedly mounted on the rotating shaft, the guide rod is fixedly mounted on the mounting frame, the moving cylinder is mounted on the guide rod via the moving assembly, the rotating disc is rotatably mounted on the moving cylinder, and the support assembly is mounted on the mounting frame.

[0007] The movable component includes a movable rod and a threaded ring, the threaded ring being threadedly engaged with the guide rod, and the movable rod being fixedly mounted on the threaded ring.

[0008] The movable component further includes a fixed rod and a fixed ring, wherein the fixed rod is fixedly mounted on the threaded ring, and the fixed ring is fixedly mounted on the fixed rod.

[0009] The support assembly includes a sliding frame and a support rod. A groove is provided on one side of the mounting frame. The sliding frame is slidably mounted on the mounting frame and located in the groove. The support rod is fixedly mounted in the sliding frame.

[0010] The receiving device includes a limiting strip and a receiving box. The limiting strip is fixedly installed on the base plate. The receiving box is placed on the base plate and contacts the limiting strip.

[0011] This utility model discloses an automatic sandblasting machine for aluminum alloy profiles. In use, the sand inlet pipe is connected to an external sandblasting device. The aluminum alloy profile is placed on the support rod of the sliding frame, ensuring contact between the profile and the abutment plate. Then, the fixing ring is rotated, causing the fixing rod to drive the threaded ring to rotate. The threaded ring, through the threaded engagement with the guide rod, causes the moving rod to move closer to the abutment plate. The movement of the moving rod pushes the moving cylinder and the rotating plate to abut against the other side of the aluminum alloy profile. Subsequently, the profile moves along the sliding frame... The groove pushes the sliding frame, causing it to detach from the aluminum alloy profile. An external sandblasting device then sandblasts the aluminum alloy profile through the sand inlet pipe and the spray nozzle. Simultaneously, an external motor drives the rotating shaft, causing the rotating shaft and the abutment plate to rotate the aluminum alloy profile, resulting in uniform sandblasting. The movement of the moving cylinder and the rotating disk then causes the rotating disk to abut the aluminum alloy profile against the abutment plate, rigidly fixing the profile and preventing it from detaching during sandblasting.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The first embodiment of this application is as follows:

[0020] Please see Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of an automatic sandblasting machine for aluminum alloy profiles according to the first embodiment of this utility model. Figure 2 This is an enlarged schematic diagram of point A in the first embodiment of this utility model. Figure 3 This is a structural schematic diagram of the fixing device according to the first embodiment of this utility model.

[0021] This utility model provides an automatic sandblasting machine for aluminum alloy profiles, including a base plate 101, a mounting frame 102, a sandblasting seat 103, and a receiving device. It also includes a fixing device comprising a receiving plate 106, a rotating shaft 107, a rotating disk 108, a moving cylinder 109, a guide rod 110, a moving assembly, and a support assembly. The moving assembly includes a moving rod 111 and a threaded ring 112, and further includes a fixing rod 113 and a fixing ring 114. The support assembly includes a sliding frame 115 and a support rod 116. This solution addresses the problem that while the aforementioned device uses a return spring to elastically drive the limiting plate to fix the aluminum alloy profile, the driving force of the return spring can change, causing the aluminum alloy profile to easily detach from the limiting plate during rotation, thus affecting the sandblasting process. This solution can be used in the sandblasting of aluminum alloy profiles and can also be used to solve the problem of collecting excess blasting material.

[0022] In this embodiment, the aluminum alloy profile can be fixed by the cooperation of the rotating disk 108 and the abutting disk 106, thus preventing the aluminum alloy profile from detaching during the sandblasting process.

[0023] The rotating shaft 107 is rotatably mounted on the mounting frame 102, the abutment plate 106 is fixedly mounted on the rotating shaft 107, the guide rod 110 is fixedly mounted on the mounting frame 102, the movable cylinder 109 is mounted on the guide rod 110 via the movable assembly, the rotating disk 108 is rotatably mounted on the movable cylinder 109, the support assembly is mounted on the mounting frame 102, an external motor is connected to the rotating shaft 107, the rotating shaft 107 is rotatably coupled to the mounting frame 102 via bearings, the abutment plate 106 is welded to the rotating shaft 107, and the guide rod 110... The axis of the rotating shaft 107 is coincident with the axis of the guide rod 110, which is welded to the mounting bracket 102. The moving cylinder 109 is a cylindrical structure with its two ends connected to each other. The moving disk is a disc structure. The support component can support the aluminum alloy profile. The moving component can push the moving cylinder 109. In use, the moving component pushes the moving cylinder 109, causing the moving cylinder 109 to drive the rotating disk 108 to abut the aluminum alloy profile against the abutment disk 106, so that the aluminum alloy profile is rigidly fixed and prevents the aluminum alloy profile from detaching during the sandblasting process.

[0024] Secondly, the threaded ring 112 is threadedly engaged with the guide rod 110, and the movable rod 111 is fixedly installed on the threaded ring 112. The inner side of the threaded ring 112 is threaded, and the guide rod 110 is threaded. There are three sets of movable rods 111, which are distributed in a ring around the side of the threaded ring 112. The movable rods 111 are welded to the threaded ring 112. In use, by rotating the threaded ring 112, the threaded ring 112 drives the movable rods 111 to move during the rotation. The movement of the movable rods 111 pushes the movable cylinder 109 to move, thereby realizing the movement drive of the movable cylinder 109.

[0025] Furthermore, the fixing rod 113 is fixedly installed on the threaded ring 112; the fixing ring 114 is fixedly installed on the fixing rod 113. There are multiple sets of fixing rods 113, which are distributed in a ring around the outside of the threaded ring 112. The fixing ring 114 is welded to the multiple sets of fixing rods 113. The axis of the fixing ring 114 coincides with that of the threaded ring 112. By rotating the fixing ring 114, the fixing rod 113 drives the threaded ring 112 to rotate, thereby realizing the rotational drive of the threaded ring 112.

[0026] Finally, a sliding groove 117 is provided on one side of the mounting bracket 102, and the sliding frame 115 is slidably mounted on the mounting bracket 102 and located in the sliding groove 117; the support rod 116 is fixedly mounted in the sliding frame 115, the sliding frame 115 is a square frame structure, and there are multiple sets of support rods 116, which are distributed in parallel in the sliding frame 115. Through the cooperation of the sliding frame 115 and the support rods 116, the aluminum alloy profile can be supported.

[0027] In this embodiment, during use, the sand inlet pipe 105 is connected to an external sandblasting device. The aluminum alloy profile is placed on the support rod 116 of the sliding frame 115, so that the aluminum alloy profile contacts the abutment plate 106. Then, the fixing ring 114 is rotated, so that the fixing rod 113 drives the threaded ring 112 to rotate. The threaded ring 112, through the threaded engagement of the guide rod 110, causes the threaded ring to drive the moving rod 111 closer to the abutment plate 106. The movement of the moving rod 111 pushes the moving cylinder 109 and the rotating plate 108 to abut against the other side of the aluminum alloy profile, and then along the sliding groove 11. 7. Push the sliding frame 115 to separate it from the aluminum alloy profile. The aluminum alloy profile is then sandblasted by an external sandblasting device through the sand inlet pipe 105 and the spray hole 104. At the same time, the rotating shaft 107 is driven by an external motor, causing the rotating shaft 107 and the abutment plate 106 to rotate the aluminum alloy profile, resulting in uniform sandblasting of the aluminum alloy profile. The movement of the moving cylinder 109 and the rotating disk 108 drives the rotating disk 108 to abut the aluminum alloy profile against the abutment plate 106, thus rigidly fixing the aluminum alloy profile and preventing it from detaching during the sandblasting process.

[0028] The second embodiment of this application is as follows:

[0029] Please see Figure 4 ,in Figure 4 This is a schematic diagram of the overall structure of an automatic sandblasting machine for aluminum alloy profiles according to the second embodiment of the present invention. Based on the first embodiment, the automatic sandblasting machine for aluminum alloy profiles in this embodiment further includes a receiving device, which includes a limiting strip 201 and a receiving box 202.

[0030] In this embodiment, the material receiving box 202 facilitates the collection of excess spray material.

[0031] The limiting strip 201 is fixedly installed on the base plate 101; the receiving box 202 is placed on the base plate 101 and in contact with the limiting strip 201. There are two sets of limiting strips 201, which are symmetrically arranged on both sides of the base plate 101. The receiving box 202 is placed between the limiting strips 201 on both sides, and the opening of the receiving box 202 is located at the top. The limiting strip 201 facilitates the limiting of the receiving box 202. During the sandblasting process, excess spray material of the aluminum alloy profile will fall into the receiving box 202. When it is necessary to clean the spray material, the receiving box 202 can be pulled out and poured out. Thus, the receiving box 202 facilitates the collection of excess spray material.
