DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-5, a pneumatic connection fixing device, comprising a fixing mechanism 1 and a docking mechanism, the fixing mechanism 1 comprising a mounting plate 2, a shell 3, a cavity 4, a top block 6 and a connecting ring 7, a ball hole 8, a steel column, a groove 10, a fixing block 11, a spring 12, a push plate 13, a pull rod 14, a sealing plate 15, a bolt 16 and a positioning column 17, the shell 3 is arranged on the top of the mounting plate 2, the cavity 4 is opened on the shell 3, a telescopic cylinder is arranged at the bottom of the cavity 4, the top of the telescopic cylinder is connected to the top block 6, the connecting ring 7 is arranged on the top of the shell 3, the connecting ring 7 is communicated with the cavity 4, the ball hole 8 is opened on the connecting ring 7, the groove 10 is opened on the connecting ring 7, the groove 10 is connected to the The inside of the ball hole 8 is connected, and the fixed block 11 is placed in the groove 10. The fixed block 11 has the same height as the groove 10. One end of the spring 12 is connected to the fixed block 11, and the other end of the spring 12 contacts the push plate 13. One end of the push plate 13 passes through the groove 10 and is connected to the steel column. The top of the groove 10 passes through the connecting ring 7, and the sealing plate 15 is connected to the top of the connecting ring 7 through the bolt 16. One end of the pull rod 14 is connected to the top of the fixed block 11, and the other end of the pull rod 14 passes through the sealing plate 15. The positioning column 17 is arranged on the top of the shell 3. The docking tooling 22 is provided with a positioning hole 5, and the positioning column 17 matches the positioning hole 5.

[0027] Working steps: the fixing mechanism 1 is docked with the external equipment through the mounting plate 2, and then the equipment is connected to the external mains power and controller to power the equipment and be able to operate the equipment, and then the positioning hole 5 on the docking tool 22 is docked with the positioning column 17 on the housing 3, and the positioning column 17 is inserted into the positioning hole 5 to accurately position the two. After the positioning column 17 is inserted into the positioning hole 5, the connecting ring 7 is located in the middle of the docking tool 22, and the steel ball 9 is located in the slotted position of the inner wall of the docking tool 22, and then the telescopic cylinder in the cavity 4 is started through the external controller. The top block 6 is driven to rise. The top block 6 is similar to a cone shape. Therefore, when the top block 6 rises, the outer wall of the top block 6 will slowly contact the steel ball 9, push the steel ball 9 out, and make the steel ball 9 extend out of the ball hole 8 and extend into the slotted position of the inner wall of the docking tooling 22. When the steel ball 9 is pushed out, the push plate 13 will move in the groove 10, and the spring 12 on the fixed block 11 will be compressed. A telescopic rod is provided inside the spring 12, one end of the telescopic rod is connected to the fixed block 11, and the other end of the telescopic rod is in contact with the push plate 13, which can prevent the spring 12 from shaking. The docking can be completed through the above steps.

[0028] Replacement of spring 12: When spring 12 is used for a long time and needs to be replaced, first use an external screwdriver to tighten the bolt 16 to separate the bolt 16 from the sealing plate 15, and then separate the sealing plate 15 from the top of the connecting ring 7. At this time, the groove 10 will be exposed, and the fixing block 11 is connected to the height of the groove 10. After the sealing plate 15 is separated from the connecting ring 7, the fixing block 11 will lose its limit, and the sealing plate 15 will not contact the top of the fixing block 11. After the sealing plate 15 is separated, the pull rod 14 will not separate the sealing plate 15. Then the staff can separate the fixing block 11 from the groove 10 by pulling the pull rod 14. The spring 12 is set on the fixing block 11, so that the spring 12 will be removed. When removing the spring 12, the spring 12 can be moved with an external small iron sheet to separate one end of the spring 12 from the push plate 13, thereby reducing the friction when the spring 12 is removed. Then replace it with a new part. The new part can be purchased from the manufacturer and will not be described in detail here.

[0029] The position and size of the groove 10 herein will not affect the movement of the steel ball 9 in the ball hole 8, and the manufacturer will fully consider this situation during production.

[0030] In this embodiment, a protection mechanism is provided on the fixing mechanism 1, and the protection mechanism includes a protective shell 18, a positioning block 19, a connecting block 20, a rubber block 21 and a clamping column 23. The protective shell 18 is sleeved on the top of the connecting ring 7, and the size of the protective shell 18 is larger than the size of the connecting ring 7. One end of the positioning block 19 is connected to the protective shell 18, and the other end of the positioning block 19 partially extends into the outer shell 3. One end of the connecting block 20 is connected to the protective shell 18, and the other end of the connecting block 20 is connected to the rubber block 21. The clamping column 23 is arranged on the outer shell 3, and the other end of the rubber block 21 is sleeved on the clamping column 23.

[0031] When the fixing mechanism is not in use and is stored in a warehouse or other place, the protective shell 18 in the protective mechanism can achieve a protective effect, which can prevent foreign particles from entering the cavity 4 and avoid affecting the telescopic cylinder in the cavity 4. When the equipment needs to be used, the staff pulls the rubber block 21 with force to separate the rubber block 21 sleeved on the clamping column 23 from the clamping column 23, and then lifts the protective shell 18 upward to separate the positioning block 19 from the inside of the shell 3. The protective shell 18 can be separated from the shell 3, and then the fixing mechanism 1 can be used. The shell 3 is provided with a groove body that matches the positioning block 19, which is not described in detail here. The rubber block 21 in the text is separated from the clamping column 23. The rubber block 21 has a certain elasticity, so the rubber block 21 can be pulled with force. When the rubber block 21 is sleeved on the clamping column 23, the protective shell 18 will generally not be separated from the outer shell 3. Even if the staff uses a lot of force, the rubber block 21 can only be stretched a small distance, and the protective shell 18 will only rise a short distance. Only by pulling the rubber block 21 with force to separate the rubber block 21 from the clamping column 23 can the protective shell 18 be separated from the outer shell 3. Therefore, under normal circumstances, the protective shell 18 will not be separated from the outer shell 3 unless the rubber block 21 is pulled hard by human. The rubber block 21 is made of butyl rubber and can withstand long-term stretching without being easily damaged.

[0032] The telescopic cylinder in this article adopts an electric cylinder, which is equipped with an electric motor inside. Usually a stepper motor or a servo motor is used to convert electrical energy into power, and the piston of the cylinder is pushed to extend and retract through a screw or chain drive system. This structure is connected to the external mains as a whole to power the entire equipment, which will not be described in detail here.

[0033] In order to improve the firmness of the connection between the sealing plate 15 and the connecting ring 7, in this embodiment, a plurality of bolts 16 are provided, and the plurality of bolts 16 are symmetrically arranged.

[0034] In order to improve the stability and docking effect of the fixing mechanism 1 and the docking tool 22, in this embodiment, two positioning columns 17 are provided, two positioning holes 5 are opened, and the two positioning columns 17 are symmetrically arranged, and the two positioning holes 5 are symmetrically arranged.

[0035] In this embodiment, the outer wall of the protective shell 18 is provided with a wear-resistant layer, and the wear-resistant layer is fixedly connected to the outer wall of the protective shell 18. The wear-resistant layer is made of PVC material. The wear-resistant layer on the outer wall of the protective shell 18 can achieve a wear-resistant effect and prevent the protective shell 18 from being worn.

[0036] In order to improve the wear-resistant effect, in this embodiment, a plurality of wear-resistant grooves are provided on the wear-resistant layer.

[0037] In order to improve the connection effect, in this embodiment, the positioning column 17 is welded to the housing 3.

[0038] The shell 3 mentioned above has poor strength. In order to solve this problem, in this embodiment, the shell 3 is made of alloy steel.

[0039] The sizes of all components in this structure are not specifically limited here and need to be produced according to actual conditions. The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and wiring layout in detail.
