Description

Technical Field

[0001] The utility model relates to the technical field of frame connection, and particularly to a fixing structure for a turning shaft. Background Art

[0002] In the casting of workpieces, after the blank is cast and polished, it is necessary to spray oil or coating on the surface for anti-corrosion treatment to ensure the service life and quality of the workpiece. During the spraying process, the workpiece needs to be continuously turned to ensure that all surfaces of the workpiece can be sprayed. Considering the actual production situation, for workpieces of various different models and sizes, different mounting frames are required to mount different workpieces, and different models of mounting frames can be connected to the same turning device to achieve the turning of the workpiece. However, in actual use, the mounting frame and the turning device are connected by bolts. When a large workpiece needs to be fixed on the mounting frame, due to the continuous turning of the turning device, the bolts connecting the mounting frame and the turning device need to bear a large shear force, resulting in damage to the bolt threads or overall fracture, leading to potential safety hazards. Summary of the Utility Model

[0003] The utility model provides a fixing structure for a turning shaft, which solves the problem in the related art that the bolts connecting the mounting frame and the turning device bear too large a shear force and may cause potential safety hazards.

In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0031] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "mount", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0033] Refer to Figures 1 to 7, which is the first embodiment of the present utility model, proposes a fixing structure for the turning shaft, enabling the turning frame 1 to be fixedly connected to the mounting frame 2, including: a rotating shaft 110 rotatably arranged on the turning frame 1, and the rotating shaft 110 has a mounting groove 111; a mounting block 210 is arranged on the mounting frame 2, and the mounting block 210 is installed in cooperation with the mounting groove 111; a fastening sleeve 3 is slidably arranged on the rotating shaft 110, and the fastening sleeve 3 has a mating hole 310. After the fastening sleeve 3 slides, the mating hole 310 cooperates with the mounting block 210 and the rotating shaft 110.

[0034] In this embodiment, the workpiece to be processed needs to be installed on the mounting frame 2. The turning frame 1 is used to fix the mounting frame 2 and drive the mounting frame 2 to rotate at the same time, so that all aspects of the workpiece can be sprayed. The mounting block 210 is square, can enter the mounting groove 111 on the rotating shaft 110 and fits tightly, preventing the mounting frame 2 from shaking when rotating, ensuring the stability of the mounting frame 2, reducing the generation of shear force, and reducing potential safety hazards. The fastening sleeve 3 slides on the rotating shaft 110. When the mounting frame 2 is installed on the turning frame 1, the mounting block 210 will enter the mounting groove 111. At this time, slide the fastening sleeve 3 so that the mounting block 210 and the rotating shaft 110 enter the mating hole 310, and the connection between the mounting block 210 and the rotating shaft 110 becomes tighter. It will not become detached due to rotation, improving the connection performance. Compared with the traditional method of connecting two parts by bolts, the design of the mounting groove 111 changes the shear force originally borne by the bolts to the mounting groove 111 outside the rotating shaft 110. While expanding the bearing area, it also changes the bearing material, improving the overall strength and enhancing the safety of the structure. It also makes the fixing structure more convenient to install during use.

[0035] As a further technical solution, the height of the mounting block 210 is higher than that of the mounting groove 111.

[0036] In this embodiment, the height of the mounting block 210 is higher than that of the mounting groove 111. Therefore, after installation, the part of the mounting block 210 that protrudes above the rotating shaft 110 forms a structure similar to a keyway and a key, and both are connected by the fastening sleeve 3, enabling the fastening sleeve 3 to bear part of the shear force at the same time. While preventing the mounting frame 2 from falling due to rotation, it also assists the rotating shaft 110 to resist the shear force, further improving the safety performance of the equipment.

[0037] As a further technical solution, the mounting block 210 has a plurality of through holes 211, the rotating shaft 110 has a plurality of screw holes 112, and the positions of the screw holes 112 correspond to those of the through holes 211. It further includes: a mounting bolt 4 detachably arranged on the rotating shaft 110.

[0038] In this embodiment, there are several through holes 211 on the mounting block 210, which can allow the mounting bolts 4 to be placed into the through holes 211 and pass through the mounting block 210 to cooperate with the threaded holes 112 on the rotating shaft 110. At this time, the mounting bolts 4 only need to play the role of fixing the mounting block 210 and will not bear excessive shear force. This not only prevents the threads from being damaged but also avoids the situation where the mounting bolts 4 break, improving safety. There are multiple mounting bolts 4. When the fastening sleeve 3 slides, the mounting bolts 4 can fix the fastening sleeve 3 to prevent the fastening sleeve 3 from continuing to slide and causing the mounting block 210 to leave the mating hole 310, ensuring that the fastening sleeve 3 can always play a fastening role during use and will not be affected by external forces or other factors, further improving safety.

[0039] As a further technical solution, there is a sliding groove 113 on the rotating shaft 110. The sliding groove 113 communicates with the mounting groove 111. There is a clamping groove 212 on the mounting block 210. It further includes: a clamping block 5 slidably arranged in the sliding groove 113. After the clamping block 5 slides, it enters or leaves the clamping groove 212.

[0040] In this embodiment, the clamping block 5 is used to clamp the sliding groove 113 and the clamping groove 212, playing the same role as the mounting bolts 4, preventing the mounting block 210 from falling off the rotating shaft 110 and ensuring that the mounting block 210 can be more tightly connected to the rotating shaft 110. The clamping block 5 can slide in various ways to ensure that it can enter the mounting block 210.

[0041] As a further technical solution, the sliding groove 113 penetrates the rotating shaft 110, and the clamping block 5 is arranged on the fastening sleeve 3.

[0042] In this embodiment, the clamping block 5 passes through the sliding groove 113 and is connected to the fastening sleeve 3. When the fastening sleeve 3 is installed in place, the clamping block will be brought into the clamping groove 212 together with the fastening sleeve 3 to clamp the mounting block 210, simplifying the installation steps and also improving safety.

[0043] As a further technical solution, it further includes: a ferromagnetic part 6 is arranged on the rotating shaft 110, and the ferromagnetic part 6 is used to attract the fastening sleeve 3.

[0044] In this embodiment, the ferromagnetic part uses a magnet or other workpieces that can play the same role. Through the design of the ferromagnetic part 6, after the mounting bracket 2 is removed, the ferromagnetic part 6 will suck the fastening sleeve 3 onto itself, preventing the fastening sleeve 3 from leaving the rotating shaft, avoiding the loss of the fastening sleeve 3, and also facilitating the next installation.

[0045] As a further technical solution, it further includes: a driving part 7 is arranged on the mounting bracket 2, and the driving part 7 is used to drive the rotating shaft 110 to rotate.

[0046] In this embodiment, the driving member 7 is a motor, and can also be a motor or other similar devices. The driving member 7 can provide stable power to the rotating shaft 110 to make the rotating shaft rotate smoothly.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
