Technical Field

[0001] The utility model relates to the technical field related to vacuum diffusion welding equipment, in particular to an anti-falling self-locking mechanism for a vacuum diffusion welding machine door. Background Art

[0002] Vacuum diffusion welding can weld almost all metal and non-metal materials, with high weld precision, small deformation, and no fusion welding defects in the weld. It is the only method to make vacuum-tight, heat-resistant, vibration-resistant and non-deformation joints, so it is widely used in industrial production.

[0003] In vertical vacuum equipment that opens and closes from the bottom, the lower cover is generally lifted and lowered by a ball screw or a cylinder. The anti-fall function is mainly achieved by the brake provided by the ball screw drive motor, or the self-locking function of the cylinder.

Simple motor brakes or oil cylinder anti-fall self-locking appear monotonous, and their safety performance is relatively general.

[0005] In view of the above-mentioned defects, the designers actively carried out research and innovation in order to create a vacuum diffusion welding machine door anti-fall self-locking mechanism to make it more valuable for industrial use. Utility Model Content

[0011] As a further improvement of the present utility model, the lifting module includes a lifting motor, a reducer and a transmission lead screw. The driving end of the lifting motor is connected to at least one transmission lead screw distributed along the vertical direction after passing through the reducer. The transmission lead screw drives the equipment platform above to move in the vertical direction through a lead screw nut.

[0012] As a further improvement of the present utility model, a clamping block is installed at the bottom of the equipment platform on the inner side of the column.

[0029] Embodiment

[0030] As Figures 1 to 3 shown,

[0031] An anti-falling self-locking mechanism for the door of a vacuum diffusion welding machine, comprising a base 1, a lifting module and an equipment platform 6. The lifting module installed on the base 1 drives the upper equipment platform 6 to move in the vertical direction. The lifting module includes a lifting motor 3, a reducer 4 and a transmission lead screw 5. The driving end of the lifting motor 3 is connected to at least one transmission lead screw 5 distributed along the vertical direction after passing through the reducer 4. The transmission lead screw 5 drives the upper equipment platform 6 to move in the vertical direction through a lead screw nut.

[0032] Four columns 2 are installed on the base 1 and are respectively located at the four diagonal corners of the base 1. A chute plate 8 is installed at the bottom of the equipment platform 6 outside the column 2. Ten anti-falling self-locking components 9 are evenly distributed along the vertical direction on the column 2. The distance between two adjacent anti-falling self-locking components 9 is 200 mm.

[0033] The anti-falling self-locking component 9 includes a fixed connecting rod 10, a first moving connecting rod 11, a second moving connecting rod 12, a rotating connecting rod 13 and a rotating chute plate 14. The fixed connecting rod 10 is welded to the column 2 through a pin 17. The pin 17 on the outside of the first moving connecting rod 11 can be adapted to the chute 17 on the chute plate 8. The middle part of the first moving connecting rod 11 is connected to the outside of the fixed connecting rod 10 through a pin 17. The inside of the first moving connecting rod 11 is connected to the outside of the second moving connecting rod 12 through a pin 17. The outside of the rotating connecting rod 13 is connected to the inside of the fixed connecting rod 10 through a pin 17. The inside of the second moving connecting rod 12 is connected to the middle part of the rotating connecting rod 13 through a pin 17. The pin 17 on the inside of the rotating connecting rod 13 can be adapted to the rotating chute 15 on the rotating chute plate 14.

[0034] Among them, the chute plate 8 is made of medium carbon steel quenched to improve hardness and extend service life.

[0035] A clamping block 7 is installed at the bottom of the equipment platform 6 inside the column 2. The clamping block 7 can be adapted to the pin 17 located in the rotating chute 15 below to achieve the clamping function.

[0036] A brief description of the working principle of the present utility model:

[0037] The anti-falling self-locking component 9 is a protection device in addition to the motor brake, which can be automatically opened and reset. The initial state is a closed state, that is, the anti-falling state.

[0038] The equipment platform 6 moves downward. The pin 17 on the outside of the first moving link 11 cooperates in the chute 17 and moves to the right. The second moving link 12 drives the rotating link to move to the higher part of the rotating chute 15 and stays there. When the platform descends below the anti-falling self-locking component 9, the pin 17 on the outside of the first moving link 11 separates from the chute 17, and the rotating link 13 returns to its original position by self-resetting. Repeat this step to move downward once to move the rotating link 13 to the higher position. Keep the rotating link 13 at the higher position when the locking block 7 passes through, and then it will reset itself automatically.

[0039] The equipment platform 6 moves upward. The pin 17 on the outside of the first moving link 11 cooperates in the chute 17. The first moving link 11 moves horizontally to the right, drives the second moving link 12 to move to the right, and drives the rotating link 13 to slide upward. When the locking block 7 passes through the rotating chute plate 14, the rotating link 13 stays at the higher position. When the locking block 7 is higher than the rotating chute plate 14, the pin 17 on the outside of the first moving link 11 slides in the chute 17 to lower the rotating link 13 to the lowest point of the rotating chute 15, and continue to implement the anti-falling function.

[0040] Such as Figure 3 , any one of the anti-falling self-locking components 9 includes two first moving links 11, a second moving link 12, a rotating link 13 and a rotating chute plate 14, which form a component and perform a function.

[0041] The first moving link 11 can only move horizontally, and the pin on the outside of the first moving link 11 moves in the chute 17.

[0042] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, 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, so it cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0043] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "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; 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 through specific situations.

[0044] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. It should be pointed out that for those of ordinary skill in the technical field, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
