Description

Technical Field

[0001] This utility model relates to the field of bracket technology, specifically a die-cast bracket with a rotating structure. Background Technology

[0002] Die casting is a metal forming process in which molten metal is injected into a precision mold cavity under high pressure and then rapidly solidifies. Die-cast brackets are key support components in the fields of machinery, electronics, and automobiles, and are widely used in scenarios such as motor installation, sensor fixing, and structural component connection.

[0003] A search revealed a utility model patent with Chinese patent publication number CN202685197U, which discloses a hinge holder for an injection molding machine. This invention solves technical problems such as unreasonable design in existing technologies. The hinge holder for the injection molding machine includes a base, on which two hinge heads are arranged side-by-side with a gap between them. Each hinge head has a connecting hole at its end away from the base, and the connecting holes are coaxially aligned. The hinge heads and the base are integrally connected.

[0004] As mentioned above, the shape of the hinge hole may change due to issues such as mold manufacturing and wear, as well as material shrinkage and deformation during production. Some hinges that require bearing installation may inevitably experience problems such as bearing instability or inability to be installed, indicating room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a die-cast bracket with a rotating structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-cast bracket with a rotating structure, comprising a connecting part, two vertically arranged support parts on the top outer wall of the connecting part, an arc-shaped groove inside the support parts, a mounting frame placed on the top of the connecting part, the mounting frame surrounding the two support parts, two clamping parts inside the mounting frame, an arc-shaped groove inside the two clamping parts, a mounting ring placed between the support parts and the clamping parts, the mounting ring being circularly arranged, and both the connecting part and the mounting frame having a connecting structure, the connecting structure including four connecting holes and two clearance grooves.

[0007] As a further preferred embodiment of this technical solution, the four connecting holes are respectively located at the four corners of the bottom inner wall of the mounting bracket, and the two clearance grooves are both located on the top outer wall of the connecting part, with the four connecting holes respectively located directly above the two clearance grooves.

[0008] The bracket is designed to accommodate standard bearing installations, preventing instability due to shape differences and improving the device's adaptability. The mounting ring is placed inside the groove at the top of the support unit. The mounting bracket is then fitted over the two supports, with the clamping part inside the bracket covering the upper half of the mounting ring. Bolts are then passed through the connecting hole and the clearance groove and connected to the external structure. At this point, the connecting part and the mounting bracket are fixed in position, and the mounting ring is clamped and will not move freely. Because the bearing hole inside the mounting ring is a standard hole, the bearing can be installed precisely within it, and the presence of the mounting ring also prevents bearing wear.

[0009] As a further preferred embodiment of this technical solution, a blocking part is provided on each side of the inner circumference of the two support parts that are far apart from each other, and the radius of the blocking part is smaller than the radius of the groove at the top of the support part.

[0010] As a further preferred embodiment of this technical solution, a number of equally spaced reinforcing ribs are provided on the bottom of the outer wall of each of the two supporting parts that are far apart from each other.

[0011] As a further preferred embodiment of this technical solution, a connection hole is provided at each of the four corners of the top outer wall of the connecting part.

[0012] As a further preferred embodiment of this technical solution, the angles of both clamping parts are less than 180 degrees.

[0013] As a further preferred embodiment of this technical solution, the connecting part, the two supporting parts, the mounting bracket and the two clamping parts are all made of aluminum alloy.

[0014] This utility model provides a die-casting bracket with a rotating structure, which has the following advantages:

[0015] This utility model, by setting up a mounting bracket, a clamping part, and a mounting ring, enables the bracket to adapt to the installation and fixing of standard bearings, avoiding the problem of unstable bearing installation due to differences in shape, thus improving the adaptability of the device. The mounting ring is placed inside the groove at the top of the support part, and then the mounting bracket is sleeved on the outside of the two support parts. The clamping part inside the mounting bracket will cover the upper half of the mounting ring. Then, the bolt is passed through the connecting hole and the clearance groove and connected to the external structure. At this time, the position of the connecting part and the mounting bracket is fixed, and the mounting ring is clamped and will not move arbitrarily. Since the bearing hole inside the mounting ring is a standard hole, the bearing can be installed exactly inside it, and the presence of the mounting ring also prevents the bearing from being worn.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 3 As shown, in this embodiment, a die-cast bracket with a rotating structure includes a connecting part 1. The top outer wall of the connecting part 1 is provided with two vertically arranged support parts 5. The support parts 5 are provided with arc-shaped grooves. A mounting bracket 6 is placed on the top of the connecting part 1. The mounting bracket 6 surrounds the two support parts 5. The mounting bracket 6 is provided with two clamping parts 7. The two clamping parts 7 are also provided with arc-shaped grooves. A mounting ring 8 is placed between the support parts 5 and the clamping parts 7. The mounting ring 8 is arranged in a circular shape. Both the connecting part 1 and the mounting bracket 6 are provided with a connecting structure. The connecting structure includes four connecting holes 9 and two clearance grooves 3.

[0023] Four connecting holes 29 are respectively located at the four corners of the bottom inner wall of the mounting bracket 6, and two clearance grooves 3 are respectively located on the top outer wall of the connecting part 1. The four connecting holes 29 are respectively located directly above the two clearance grooves 3.

[0024] Place the mounting ring 8 inside the groove at the top of the support part 5, then put the mounting bracket 6 on the outside of the two support parts 5. The clamping part 7 inside the mounting bracket 6 will cover the upper half of the mounting ring 8. Then, pass the bolt through the connecting hole 2 9 and the relief groove 3 and connect it to the external structure. At this time, the connecting part 1 and the mounting bracket 6 are fixed in position, and the mounting ring 8 is clamped and will not move at will. Since the bearing hole inside the mounting ring 8 is a standard hole, the bearing can be installed in it. And because of the presence of the mounting ring 8, the bearing can also be prevented from being worn.

[0025] like Figure 2 and Figure 4As shown, a blocking part 10 is provided on the side of the inner circumference of the two support parts 5 that are far apart from each other. The radius of the blocking part 10 is smaller than the radius of the groove at the top of the support part 5, which can limit the position of the mounting ring 8, thereby preventing the mounting ring 8 and the bearing from shifting during use.

[0026] like Figure 1 and Figure 2 As shown, several equally spaced reinforcing ribs 4 are provided on the bottom of the outer wall of the two support parts 5 on the side that are far apart from each other, which can increase their stability and improve the overall strength of the support.

[0027] like Figure 1 and Figure 2 As shown, a connection hole 2 is provided at each of the four corners of the top outer wall of the connecting part 1. The connecting parts can be reinforced by passing through the connection holes 2.

[0028] like Figure 1 As shown, the angles of the two clamping parts 7 are both less than 180 degrees. This design facilitates the placement and removal of the mounting ring 8, and at the same time provides sufficient clamping force to the mounting ring 8 after installation, preventing the mounting ring 8 from becoming loose due to the large diameter of the groove.

[0029] like Figure 1 and Figure 2 As shown, the connecting part 1, the two supporting parts 5, the mounting bracket 6, and the two clamping parts 7 are all made of aluminum alloy. The density of aluminum alloy die castings can reach 2.7-2.8 g / cm³. 3 After T6 heat treatment, the tensile strength can reach over 350MPa.

[0030] This utility model provides a die-casting bracket with a rotating structure, the specific working principle of which is as follows:

[0031] When the device is in operation, the mounting ring 8 is placed inside the groove at the top of the support part 5. Then, the mounting bracket 6 is fitted over the two support parts 5. The clamping part 7 inside the mounting bracket 6 will cover the upper half of the mounting ring 8. Then, the bolt is passed through the connecting hole 9 and the clearance groove 3 and connected to the external structure. At this time, the connecting part 1 and the mounting bracket 6 are fixed in position, and the mounting ring 8 is clamped and will not move arbitrarily. Since the bearing hole inside the mounting ring 8 is a standard hole, the bearing can be installed exactly inside it, and the presence of the mounting ring 8 can also prevent the bearing from being worn. The outer side of the support part 5 is evenly distributed with reinforcing ribs 4, which can increase its stability and improve the overall strength of the bracket. The diameter of the blocking part 10 set in the groove at the top of the support part 5 is smaller than the diameter of the groove, which can limit the position of the mounting ring 8, thereby preventing the mounting ring 8 and the bearing from shifting during use.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
