DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-7 The present invention is further described:

[0020] A device for automatically replacing sleeves for tire installation, a fixed plate 1 is rotatably connected to a cylinder a2, cylinder a2 is hinged to a locking turntable 3, the locking turntable 3 is rotatably connected to the fixed plate 1, a through hole a3.1 and a locking arc 3.2 are formed on the locking turntable 3, a through hole b is formed on the fixed plate 1 below the through hole a3.1, through hole b is directly opposite to the through hole c4.1 on the push plate 4 below, the push plate 4 is connected to the cylinder b5, a lifting base plate 7 is provided at the bottom of the push plate 4, a sleeve placing ring 8 is fixed on the lifting base plate 7, the lifting base plate 7 is connected to the cylinder c9, and the lifting base plate 7 is slidably connected to the guide column 10.

[0021] A guide shaft 6 is provided at the bottom of the fixing plate 1 , and the guide shaft 6 penetrates through and is slidably connected to the push plate 4 .

[0022] The top of the guide column 10 is connected to the fixing plate 1 .

[0023] The inner wall of the sleeve placement ring 8 is provided with a positioning surface a8.1 for positioning the sleeve connector 11.

[0024] The sleeve connector 11 is fixed to the top of the sleeve, and a positioning surface b11.1 matching the positioning surface a8.1 is provided at the bottom of the sleeve connector 11. A square connecting cavity 11.3 matching the quick-change connector is provided at the top of the side of the sleeve connector 11, and a fixing hole 11.2 is provided on the side of the connecting cavity 11.3.

[0025] The tightening end of the tightening shaft is fixed with a quick-change connector (such as Figure 4 As shown), through the quick-change joint and the sleeve connector 11 at the top of the sleeve (as shown Figure 5 The quick-change connector is a mature product available on the market. The model of the quick-change connector is ACTION69114C24. To facilitate the explanation of the working principle of the present invention, the functions of the quick-change connector are briefly introduced as follows. The quick-change connector includes an upper edge 12.2, an annular groove 12.5, a lower edge 12.3, and a retractable positioning ball 12.1 on a connecting column 12.4 at the bottom. In a natural state, the positioning ball 12.1 protrudes from the surface of the connecting column 12.4. When the upper edge 12.2 and the lower edge 12.3 are compressed together, the positioning ball 12.1 retracts into the connecting column 12.4.

[0026] Sleeve connector 11 (such as Figure 5 As shown in the figure, it is fixed to the top of the sleeve, and a positioning surface b11.1 matching with the positioning surface a8.1 is provided at the bottom of the sleeve connector 11. A connecting cavity matching with the quick-change connector is provided at the top of the sleeve connector 11. A fixing hole 11.2 is provided on the side of the connecting cavity. The fixing hole 11.2 is used to accommodate the positioning ball 12.1 on the connecting column 12.4.

[0027] Socket replacement requires putting the old socket back first and then taking out the new socket.

[0028] When the old sleeve is put back, the tightening shaft is moved above the locking turntable 3, and then the tightening shaft drives the sleeve and the sleeve connector 11 to rotate and move downward. When the positioning surface b11.1 of the sleeve connector 11 is coplanar with the positioning surface a8.1, the positioning surface b11.1 area at the bottom of the sleeve connector 11 is inserted into the positioning surface a8.1 area of ​​the sleeve placement ring 8, and the tightening shaft stops rotating. At this time, the locking arc 3.2 of the locking turntable 3 is facing the ring groove 12.5 on the side of the quick-change connector, and the cylinder a2 The cylinder b5 is activated to push the locking turntable 3 to rotate, so that the locking arc 3.2 is stuck in the annular groove 12.5, and the top of the quick-change joint is positioned. The cylinder b5 is activated to push the push plate 4 upward, and the outer edge of the through hole c4.1 contacts and pushes the lower edge 12.3 of the quick-change joint upward, compressing the quick-change joint, and the positioning ball 12.5 on it is retracted and separated from the fixed block 11.2. The cylinder c9 is activated to drive the lifting base plate 7 to move downward, and the sleeve in the sleeve placement ring 8 moves downward synchronously and is separated from the quick-change joint on the tightening shaft.

[0029] When taking a new sleeve, the tightening shaft is first retracted from the old sleeve return area, and then moved to the top of the locking turntable 3 in the sleeve placement area to be replaced. During this process, the tightening shaft does not rotate, that is, the feed angle of the quick-change connector on the tightening shaft is fixed to ensure that the connecting column 12.4 matches the connecting cavity angle of the sleeve connector 11 on the new sleeve to be replaced, so that the connecting column 12.4 can be smoothly inserted into the connecting cavity and the positioning ball 12.5 can be aligned with the fixing hole 11.2. The tightening shaft drives the quick-change joint to move downward until the locking arc 3.2 of the locking turntable 3 is opposite to the annular groove 12.5 on the side of the quick-change joint. The cylinder a2 is actuated to push the locking turntable 3 to rotate, so that the locking arc 3.2 is stuck in the annular groove 12.5, and the top of the quick-change joint is positioned. The cylinder b5 is actuated to push the push plate 4 upward, and the outer edge of the through hole c4.1 contacts and pushes the lower edge 12.3 of the quick-change joint upward, compressing the quick-change joint, and the positioning ball 12.5 on it is retracted. The cylinder c9 is actuated to move the lifting bottom plate 7 upward, driving the sleeve placed in the sleeve placing ring 8 and the sleeve connector 11 to move upward, and the connecting column 12.4 is inserted into the sleeve connector 11. The positioning ball 12.5 retracted from the side of the connecting cavity 11.3 and the connecting column 12.4 is opposite to the fixing hole 11.2, and the cylinder b5 is actuated to drive the push plate 4 to move downward and separate from the lower edge 12.3 of the quick-change joint. The lower edge 12.3 moves downward, and the compressed quick-change joint returns to its natural state. The positioning ball 12.5 extends out and enters the fixing hole 11.2. The connection and fixation between the quick-change joint and the sleeve connector 11 are completed. The cylinder a2 is actuated to drive the locking turntable 3 to rotate, so that the locking arc 3.2 is separated from the annular groove 12.5, and the tightening shaft moves upward, driving the newly replaced sleeve to move upward synchronously to leave the sleeve placement area, and then move to the working area to tighten the nut.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
