Description

Technical Field

[0001] The utility model relates to the technical field of rotating loading devices, in particular to a locking mechanism and a rotating loading device. Background Art

[0002] In the production and processing of glass, rotating devices are often used for operations such as loading, processing, and unloading of glass. Exemplarily, taking loading as an example, first place an L-frame with multiple pieces of glass on one side of the upper sheet turntable of the rotating device, limit and fix it, and disassemble the packing belt. Then, rotate the upper sheet turntable to rotate the L-frame to a position where the glass can be taken one by one, and make the other side of the upper sheet turntable in a position where another L-frame can be placed. At this time, during the process of taking the glass from one L-frame, operations such as disassembling the packing belt of the glass on the other L-frame can be carried out. After both taking and disassembling are completed, by rotating the upper sheet turntable again, rotate the L-frame after taking the glass to a position where it is easy to be carried away from the upper sheet turntable, and make the disassembled L-frame in a position where the glass can be taken one by one.

[0003] In the above process, since the upper sheet turntable needs to stop and be positioned at a preset position after rotation, a limiting mechanism is provided. This limiting mechanism can directly contact the upper sheet turntable and limit the upper sheet turntable at the preset position for convenient and accurate taking. However, this limiting mechanism is easily damaged and has a short service life, which is not conducive to reducing the cost of glass production.

[0004] Based on the above, there is an urgent need for a locking mechanism and a rotating loading device to solve the above technical problems. Summary of the Utility Model

It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.

It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0038] Next, according to the attached Figure 1 to the attached Figure 8, two embodiments are used to introduce the locking mechanism and the rotating loading device provided by the present utility model. The rotating loading device includes a locking mechanism and an upper sheet turntable. The upper sheet turntable is provided with a locking hole. The locking mechanism can be inserted into the locking hole to lock the upper sheet turntable, so that the upper sheet turntable stops and is positioned at a preset position after rotation.

[0039] As Figures 1 to 4 shown, in the first embodiment of the present utility model, the locking mechanism includes a housing 1, a locking member 2, a driving member 3 and an axial transmission connection structure 4. Among them, the housing 1 is used to install the locking member 2, the driving member 3 and the axial transmission connection structure 4. A sliding cavity is formed inside the housing 1, and a first opening and a second opening are formed on the outer surface of the housing 1 for the sliding cavity. The locking member 2 is slidably disposed in the sliding cavity, and the end of the locking member 2 can extend out of the first opening and be inserted into the locking hole, thereby restricting the rotation of the upper sheet turntable and achieving the effects of positioning and locking. The driving member 3 can be a cylinder or a motor, which is fixedly arranged on the housing 1, and the output shaft 31 of the driving member 3 can extend into the sliding cavity from the second opening, so as to push and pull the locking member 2, making the locking member 2 extend out of the first opening and retract into the sliding cavity, so that both positioning and locking can be performed, and unlocking can also be performed, that is, after the locking member 2 retracts into the sliding cavity, it no longer restricts the rotation of the upper sheet turntable.

[0040] Both the locking member 2 and the output shaft 31 are arranged along a preset axis. One end of the axial transmission connection structure 4 is connected to the locking member 2, and the other end is connected to the output shaft 31. The output shaft 31 can drive the locking member 2 to move along the preset axis through the axial transmission connection structure 4. When the locking member 2 is subjected to a radial force applied by the upper sheet turntable, the two ends of the axial transmission connection structure 4 can be bent, so that the movement of the locking member 2 deviating from the preset axis due to the radial force cannot be transmitted to the output shaft 31 through the axial transmission connection structure 4, avoiding the influence of the radial force on the output shaft 31, thereby reducing the frequency of breakage of the output shaft 31, increasing the service life of the driving member 3 and the entire locking mechanism, and reducing the production cost of the glass.

[0041] As Figures 1 to 3 shown, in this embodiment, the locking mechanism further includes at least one spacer 5, and at least one spacer 5 is fixedly arranged between the driving member 3 and the housing 1. The output shaft 31 is inserted into the sliding cavity through the second opening. By reasonably setting the thickness dimension and the number of the spacers 5, the movement range of the output shaft 31 in the sliding cavity can be flexibly adjusted, so as to ensure that the locking member 2 can extend out of the first opening and be inserted into the locking hole, realizing the positioning and locking of the upper sheet turntable.

[0042] As Figure 4As shown, in this embodiment, the axial drive connection structure 4 includes an elastic connector 41. One end of the elastic connector 41 is connected to the output shaft 31, and the other end of the elastic connector 41 is connected to the locking member 2. Thus, by utilizing its deformable ability, the elastic connector 41 can be bent between the two ends, avoiding the fracture of the output shaft 31 due to the influence of radial force.

[0043] Specifically, in this embodiment, the elastic connector 41 includes a polyurethane connector, and internal threaded holes are provided at both ends of the polyurethane connector. One end of the output shaft 31 is inserted into the polyurethane connector and fixed by means of threaded connection. A connecting stud 42 is threadedly connected to the other end of the output shaft 31, and the connecting stud 42 is threadedly connected to the locking member 2, thereby realizing the fixed connection among the locking member 2, the connecting stud 42, the polyurethane connector, and the output shaft 31.

[0044] Optionally, in some other embodiments, silicone rubber or other rubber-like materials can also be used as the elastic connector 41 to connect the output shaft 31 and the locking member 2. Polyurethane has excellent mechanical properties, good wear resistance, high mechanical strength, good weather resistance, good oil resistance, and good elasticity, and has a relatively long service life. Silicone rubber materials also have good elasticity, similar to polyurethane materials. Moreover, silicone rubber also has good chemical stability and high-temperature resistance, and the products made can be used in high-temperature, high-pressure, or even low-temperature environments and also have a long service life.

[0045] Optionally, in some other embodiments, the elastic connector 41 includes a spring. One end of the spring is connected to the output shaft 31, and the other end of the spring is connected to the locking member 2, which can also connect the locking member 2 and the output shaft 31 through the spring. Since the spring itself can also be bent, the movement of the locking member 2 deviating from the preset axis due to the radial force cannot be transmitted to the output shaft 31 through the spring, avoiding the influence of the radial force on the output shaft 31, thereby reducing the fracture frequency of the output shaft 31, increasing the service life of the driving member 3 and the entire locking mechanism, and reducing the production cost of the glass.

[0046] Preferably, as Figure 3 、 Figure 4 shown, in this embodiment, the locking mechanism further includes a guide sleeve. The guide sleeve is installed at the first opening and has a through-hole. The locking member 2 slidably passes through the through-hole, and the inner diameter of the through-hole is not greater than the inner diameter of the sliding cavity. Through the guide sleeve, when the locking member 2 is subjected to a radial force, the side surface of the locking member 2 will abut against the inner wall of the through-hole. Compared with the embodiment without a guide sleeve, the guide sleeve can change the length of the force arm and the position of the fulcrum, thereby reducing the radial force received by the axial drive connection structure 4, and further reducing the radial force received by the output shaft 31, enabling the output shaft 31 to reduce the fracture frequency and have a long service life.

[0047] In the second embodiment of the present utility model, as Figures 5 to 8 shown, a similar guide sleeve and a backing plate 5 are also provided on the housing 1. Different from the first embodiment, the adopted axial transmission connection structure 4 is different.

[0048] Specifically, as Figure 8 shown, the axial transmission connection structure 4 includes a connecting pin 43. The connecting pin 43 is arranged perpendicular to the preset axis and perpendicular to the upper piece turntable. The output shaft 31 and the locking member 2 are both connected to the connecting pin 43, and at least one of the output shaft 31 and the locking member 2 is rotatably connected to the connecting pin 43. When the locking member 2 bears a radial force, the locking member 2 can rotate around the connecting pin 43, thereby preventing the radial force from being directly transmitted to the output shaft 31, and can also achieve the effect of reducing the radial force received by the output shaft 31.

[0049] More specifically, in this embodiment, the output shaft 31 is connected with a bushing 44. Two first connecting ears arranged at intervals are provided at one end of the bushing 44 close to the locking member 2. Two end portions of the connecting pin 43 are respectively fixedly inserted into the first connecting holes of the two first connecting ears. The locking member 2 is connected with a second connecting ear, and the second connecting ear has a second connecting hole. The middle part of the connecting pin 43 is rotatably inserted into the second connecting hole. Through the bushing 44, the output shaft 31, the bushing 44, the connecting pin 43 and the locking member 2 can be conveniently connected, and the radial force received by the output shaft 31 can be reduced, so that the output shaft 31 can reduce the fracture frequency and has a long service life.

[0050] The present utility model also provides a rotational loading device, which includes an upper piece turntable and the above-mentioned locking mechanism. The upper piece turntable is provided with a locking hole, and the locking member 2 of the locking mechanism can be inserted into the locking hole to lock the upper piece turntable. When the locking member 2 is applied with a radial force by the upper piece turntable, the two ends of the axial transmission connection structure 4 can be bent, so that the movement of the locking member 2 deviating from the preset axis due to the radial force cannot be transmitted to the output shaft 31 through the axial transmission connection structure 4, avoiding the influence of the radial force on the output shaft 31, thereby reducing the fracture frequency of the output shaft 31, increasing the service life of the locking mechanism and the rotational loading device, and reducing the production cost of the glass.

[0051] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
