Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary equipment for rotating shafts, and particularly to a pre-embedded bracket structure for a thermosetting DMC rotating shaft product that can avoid cracking. Background Technique

[0002] A rotating shaft, as the name implies, is an axis that must be used to connect the main components of a product and is used in rotational work to bear both bending moment and torque. An axis that must be used to connect the main components of a product and is used in rotational work to bear both bending moment and torque is called a rotating shaft. Common rotating shafts include: mobile phone rotating shafts (flip or rotating screen mobile phones); laptop computer rotating shafts; portable DVD rotating shafts; LED table lamp rotating shafts; LCD display rotating shafts; vehicle-mounted bracket rotating shafts such as GPS, etc. Wear of the rotating shaft is a common equipment problem during the use of the shaft, mainly caused by the metal properties of the shaft: Although metal has high hardness, it has poor yielding property (it cannot recover after deformation), poor impact resistance, and poor fatigue resistance. Therefore, it is easy to cause adhesive wear, abrasive wear, fatigue wear, fretting wear, etc. Most shaft wear is not easily detectable. Only when situations such as high machine temperature, large jumping amplitude, abnormal noise, etc. occur will it be noticed. However, by the time people notice, most drive shafts have been worn, resulting in machine shutdown.

[0003] When producing a rotating shaft product, a pre-embedded bracket is set inside it. After the rotating shaft product is cooled and separated from the mold, due to the different thermal expansion coefficients of the rotating shaft and the pre-embedded bracket, the shrinkage degrees of the pre-embedded bracket and the rotating shaft product are different, resulting in a poor bonding force between the two, causing cracking at the pre-embedded bracket part during testing. Therefore, a pre-embedded bracket structure for a thermosetting DMC rotating shaft product that can avoid cracking is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a pre-embedded bracket structure for a thermosetting DMC rotating shaft product that can avoid cracking, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A pre-embedded bracket structure for a thermosetting DMC rotating shaft product that can avoid cracking, including a housing. On one side inside the housing, there is a heat-conducting block. On one side of the heat-conducting block, support rods are evenly welded. One end of the support rods is welded to the housing. On one side inside the housing, first round holes are evenly opened. On one side inside the housing, second round holes are evenly opened. On one side inside the housing, two second clamping blocks are welded. On one side inside the housing, two first clamping blocks are welded. On one side inside the heat-conducting block, two first clamping grooves are opened. On one side inside the heat-conducting block, two second clamping grooves are opened. The first clamping block is clamped with the heat-conducting block through the first clamping groove. The second clamping block is clamped with the heat-conducting block through the second clamping groove.

[0006] As a further preference of the present technical solution: A fixing block is welded on one side inside the housing. A spring is welded on one side of the fixing block.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0019] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a pre-embedded support structure for a thermosetting DMC rotating shaft product that can avoid cracking, including a housing 18. On one side inside the housing 18, there is a heat conducting block 3. On one side of the heat conducting block 3, support rods 17 are evenly welded. One end of the support rod 17 is welded to the housing 18. On one side inside the housing 18, first round holes 1 are evenly opened. On one side inside the housing 18, second round holes 2 are evenly opened. On one side inside the housing 18, two second clamping blocks 10 are welded. On one side inside the housing 18, two first clamping blocks 9 are welded. On one side inside the heat conducting block 3, two first clamping slots 19 are opened. On one side inside the heat conducting block 3, two second clamping slots 20 are opened. The first clamping block 9 is clamped with the heat conducting block 3 through the first clamping slot 19, and the second clamping block 10 is clamped with the heat conducting block 3 through the second clamping slot 20. The first round holes 1 are provided to cooperate with the second round holes 2 and the heat conducting block 3 to improve the synchronization rate of the shrinkage degree of the device and the rotating shaft, and enhance the bonding effect between the device and the rotating shaft.

[0020] In this embodiment, specifically: on one side inside the housing 18, a fixing block 8 is welded. On one side of the fixing block 8, a spring 7 is welded. One end of the spring 7 is welded with a limiting plate 6. On one side of the limiting plate 6, a fixing rod 5 is welded. One end of the fixing rod 5 penetrates the housing 18, and the end of the fixing rod 5 penetrating the housing 18 is welded with an arc-shaped plate 11. The arc-shaped plate 11 is provided to cooperate with components such as the spring 7 to limit the phase in the rotating shaft.

[0021] In this embodiment, specifically: on one side of the arc-shaped plate 11, spiral grooves 12 are evenly opened. The spiral grooves 12 are provided to guide the lubricating oil in the rotating shaft and reduce the loss rate of the lubricating oil.

[0022] In this embodiment, specifically: on one side inside the housing 18, two limiting rods 4 are welded. The limiting rods 4 are provided to limit the limiting plate 6 to prevent the distance between the arc-shaped plate 11 and the phase in the rotating shaft from being too small, which may cause the arc-shaped plate 11 to affect the normal use of the rotating shaft.

[0023] In this embodiment, specifically: on one side of the arc-shaped plate 11, two fixing plates 13 are welded. The fixing plates 13 are provided to limit the arc-shaped plate 11 to prevent the arc-shaped plate 11 from rotating and shifting along with the rotating shaft.

[0024] In this embodiment, specifically: a first threaded hole 15 is formed on one side inside the fixing plate 13, a bolt 14 is threadedly connected inside the fixing plate 13 through the first threaded hole 15, two second threaded holes 16 are formed on one side of the housing 18, and one end of the bolt 14 is threadedly connected to the housing 18 through the second threaded hole 16. The bolt 14 is provided to cooperate with the first threaded hole 15 and the second threaded hole 16 to fix the position of the fixing plate 13.

[0025] Working principle or structural principle. During use, the device is embedded in the rotating shaft. When the rotating shaft is in the heating mold, the first round hole 1 cooperates with the second round hole 2 and the heat conducting block 3 to make the device heat more evenly, improving the synchronization rate of the shrinkage degree of the device and the rotating shaft during cooling. When the rotating shaft is taken out of the heating mold for cooling, if the device shrinks, the first clamping block 9 moves into the first clamping groove 19, and the second clamping block 10 moves into the second clamping groove 20, keeping the overall structure of the device stable. When the rotating shaft is in use, the spiral groove 12 guides the lubricating oil inside the rotating shaft, reducing the loss rate of the lubricating oil. The arc-shaped plate 11 positions the phase in the rotating shaft. When the device shrinks, the spring 7 cooperates with the fixing rod 5 to adjust the distance between the arc-shaped plate 11 and the housing 18. The limiting rod 4 prevents the distance between the arc-shaped plate 11 and the phase in the rotating shaft from being too small, avoiding the arc-shaped plate 11 affecting the normal use of the rotating shaft.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
