Description

Technical Field

[0001] The present invention belongs to the technical field of clamping and rotating inflation, and specifically relates to a tire clamping, rotating and inflating device for an automatic studding machine. Background Art

[0002] The invention patent with the publication number of CN116728536A discloses an anti-slip tire full-automatic studding machine and its usage method, which includes a left slide rail assembly, a right slide rail assembly, a studding slide rail assembly, a camera slide rail assembly, a tire side pressure slide rail assembly, a tire rotation driving device, a studding device, an image scanning device, a left wheel self-centering pressing member and a right wheel self-centering pressing member. After the tire is fed into the clamping station, the left slide rail assembly, the right slide rail assembly, the tire side pressure slide rail assembly and the tire rotation driving device cooperate to realize the automatic centering and clamping of the tire. Then, the image scanning device scans and collects data on the outer circumference of the rotating tire, and the control system controls the nail shooting component to control the studding device to move and adjust the rotation angle along the rolling surface and the left and right transition arc surfaces of the tire to meet the requirements of safely, efficiently and accurately shooting and planting anti-slip studs on the tire. It provides people with a full-automatic studding machine for anti-slip tires, which can independently stud various specifications of tires. When the tire automatic studding machine is performing studding production, it generally needs to clamp, rotate and inflate snow tires during operation. The original intention of this invention is to select a suitable clamping and inflation distance for various different specifications of tires to ensure the studding quality of the tires. Currently, there are several known solutions. Either the distance between each specification of tires is kept the same, or the inflation interval during the tire studding process is relatively long, which has a certain impact on the studding accuracy. After the tire is clamped, there is a lack of locking between the driving rim and the driven rim, resulting in the tire being prone to looseness. At the same time, the inflation speed of the tire is not easy to adjust, and thus, if the tire inflation speed is too high, it will cause the tire to burst. Summary of the Invention

[0003] The purpose of the present invention is to provide a tire clamping, rotating and inflating device for an automatic studding machine to solve the above problems and those mentioned in the background art.

[0004] To solve the above problems, the present invention provides the following technical solutions:

[0005] A tire clamping, rotating and inflating device for an automatic studding machine includes a driving motor and a rotating speed reducer. A support moving frame is arranged at the end of the driving motor, a driven rim is arranged on the rotating speed reducer, a driving rim is arranged on the support moving frame, a stop-back cylinder is arranged on the driving rim, an air charging pipe is arranged on the driving rim, an adjusting mechanism is arranged on the air charging pipe, and a limiting mechanism is jointly arranged on the driven rim and the driving rim.

[0006] Preferably, the adjusting mechanism includes a retaining ring fixedly connected to the inside of the charging tube. A plug is slidably connected to the inside of the retaining ring. A sliding pin is fixedly connected to the surface of the plug, and a retaining sleeve is fixedly connected to the outside of the sliding pin. The retaining sleeve is slidably connected to the charging tube, and the sliding pin is slidably connected to the charging tube. A threaded ring is threadedly connected to the outside of the charging tube. A support plate is fixedly connected to the inside of the charging tube, and a guide rod is fixedly connected to the surface of the support plate. The guide rod is slidably connected to the plug, and a spring is arranged outside the guide rod. A baffle is slidably connected to the inside of the charging tube. A sliding rod is fixedly connected to the inside of the driven rim, and the sliding rod is slidably connected to the baffle. An adjusting rod is threadedly connected to the inside of the driven rim, and a threaded tube is threadedly connected to the outside of the adjusting rod. A sliding cylinder is slidably connected to the outside of the threaded tube, and the sliding cylinder is fixedly connected to the baffle. A compression spring is arranged inside the sliding cylinder. By rotating the threaded ring to make a threaded movement with the charging tube, the distance between the plug and the retaining ring changes, and thus the air intake speed of the charging tube changes, avoiding tire burst caused by too fast inflation speed. At the same time, the baffle is elastically pressed on the driven rim by the compression spring, so that no air leakage occurs after inflation.

[0007] Preferably, a convex block is fixedly connected to the surface of the sliding pin, and the convex block is slidably connected to the threaded ring. By providing the convex block, the friction between the sliding pin and the threaded ring is reduced.

[0008] Preferably, one end of the spring is fixedly connected to the support plate, and the other end of the spring is fixedly connected to the plug. By providing the spring, the plug is facilitated to reset.

[0009] Preferably, a guide pin is fixedly connected to the outside of the threaded tube, and the guide pin is slidably connected to the sliding cylinder. By providing the guide pin, relative rotation between the threaded tube and the sliding cylinder is avoided.

[0010] Preferably, one end of the compression spring is fixedly connected to the threaded tube, and the other end of the compression spring is fixedly connected to the baffle. By providing the compression spring, the baffle is facilitated to reset.

[0011] Preferably, the limiting mechanism includes guide rails fixedly connected to the surfaces of the driven rim and the driving rim. A square sliding rod is slidably connected to the inside of the guide rails. A clamping block is fixedly connected to the end of the square sliding rod. A connecting plate is fixedly connected to the surface of the clamping block. A bidirectional screw is movably connected to the inside of the connecting plate. A pressing plate is threadedly connected to the outside of the bidirectional screw. The pressing plate is slidably connected to the clamping block. A second spring is arranged outside the bidirectional screw. By rotating the bidirectional screw to make a threaded movement with the pressing plate, the second spring squeezes the connecting plate, and thus the clamping block moves to contact the driven rim and the driving rim, squeezing and locking and limiting the driven rim and the driving rim, so that the maximum distance between the driven rim and the driving rim after being locked is limited.

[0012] Preferably, one end of the second spring is fixedly connected to the pressing plate, and the other end of the second spring is fixedly connected to the connecting plate. By providing the second spring, the connecting plate is elastically squeezed.

[0013] The beneficial effects of the present invention are as follows: The present invention relates to a tire clamping, rotating and inflating device for an automatic nail inserting machine, which has the characteristics of facilitating the adjustment of the air intake speed and locking the tire to prevent the tire from moving. In specific use, compared with the traditional tire clamping, rotating and inflating device for an automatic nail inserting machine, the tire clamping, rotating and inflating device for the automatic nail inserting machine of the present invention has the following beneficial effects:

[0014] First, by rotating the screw ring and the air charging pipe to perform a threaded movement, the distance between the plug and the retaining ring is changed, and thus the air intake speed of the air charging pipe is changed, avoiding the tire bursting caused by too fast inflation speed. At the same time, the baffle plate is elastically pressed on the driven wheel rim by the compression spring, so that no air leakage occurs after inflation.

[0015] Second, by rotating the bidirectional screw rod and the pressing plate to perform a threaded movement, the second spring squeezes the connecting plate, and thus the clamping block moves to contact the driven wheel rim and the driving wheel rim, squeezing, locking and limiting the driven wheel rim and the driving wheel rim, so that the maximum distance between the driven wheel rim and the driving wheel rim is limited after being locked.

[0024] As Figure 1-6 shown, the following technical solution is adopted in this specific implementation manner:

[0025] Example:

[0026] The tire clamping and rotating inflation device of the automatic nail setting machine includes a driving motor 1 and a rotary speed reducer 3. A support moving frame 2 is arranged at the end of the driving motor 1. A driven rim 4 is arranged on the rotary speed reducer 3. A driving rim 5 is arranged on the support moving frame 2. An anti-reverse cylinder 6 is arranged on the driving rim 5. An inflation pipe 7 is arranged on the driving rim 5. An adjusting mechanism 8 is arranged on the inflation pipe 7. A limiting mechanism 9 is jointly arranged on the driven rim 4 and the driving rim 5.

[0027] Among them, the adjusting mechanism 8 includes a retaining ring 81. The retaining ring 81 is fixedly connected to the inside of the inflation tube 7. A plug 82 is slidably connected to the inside of the retaining ring 81. A sliding pin 83 is fixedly connected to the surface of the plug 82. A retaining sleeve 84 is fixedly connected to the outside of the sliding pin 83. The retaining sleeve 84 is slidably connected to the inflation tube 7, and the sliding pin 83 is slidably connected to the inflation tube 7. A screw ring 85 is threadedly connected to the outside of the inflation tube 7. A convex block 86 is fixedly connected to the surface of the sliding pin 83. The convex block 86 is slidably connected to the screw ring 85. By providing the convex block 86, the friction between the sliding pin 83 and the screw ring 85 is reduced. A support disk 87 is fixedly connected to the inside of the inflation tube 7. A guide rod 88 is fixedly connected to the surface of the support disk 87. The guide rod 88 is slidably connected to the plug 82. A spring 89 is provided outside the guide rod 88. One end of the spring 89 is fixedly connected to the support disk 87, and the other end of the spring 89 is fixedly connected to the plug 82. By providing the spring 89, the plug 82 is facilitated to reset. A baffle 810 is slidably connected to the inside of the inflation tube 7. A sliding rod 811 is fixedly connected to the inside of the driven wheel rim 4. The sliding rod 811 is slidably connected to the baffle 810. An adjusting rod 812 is threadedly connected to the inside of the driven wheel rim 4. A screw tube 813 is threadedly connected to the outside of the adjusting rod 812. A sliding cylinder 814 is slidably connected to the outside of the screw tube 813. The sliding cylinder 814 is fixedly connected to the baffle 810. A guide pin 815 is fixedly connected to the outside of the screw tube 813. The guide pin 815 is slidably connected to the sliding cylinder 814. By providing the guide pin 815, relative rotation between the screw tube 813 and the sliding cylinder 814 is avoided. A compression spring 816 is provided inside the sliding cylinder 814. One end of the compression spring 816 is fixedly connected to the screw tube 813, and the other end of the compression spring 816 is fixedly connected to the baffle 810. By providing the compression spring 816, the baffle 810 is facilitated to reset. By rotating the screw ring 85 to make a threaded movement with the inflation tube 7, the distance between the plug 82 and the retaining ring 81 is changed, and thus the air intake speed of the inflation tube 7 is changed, avoiding tire bursting caused by too fast inflation speed. At the same time, the baffle 810 is elastically pressed against the driven wheel rim 4 by the compression spring 816, so that no air leakage occurs after inflation is completed.

[0028] Among them, the limiting mechanism 9 includes a guide rail 91. Guide rails 91 are fixedly connected to the surfaces of the driven rim 4 and the driving rim 5. A square slide bar 92 is slidably connected inside the guide rail 91. A clamping block 93 is fixedly connected to the end of the square slide bar 92. A connecting plate 94 is fixedly connected to the surface of the clamping block 93. A bidirectional screw 95 is movably connected inside the connecting plate 94. A pressing plate 96 is threadedly connected to the outer side of the bidirectional screw 95. The pressing plate 96 and the clamping block 93 are slidably connected. A second spring 97 is arranged on the outer side of the bidirectional screw 95. One end of the second spring 97 is fixedly connected to the pressing plate 96, and the other end of the second spring 97 is fixedly connected to the connecting plate 94. By arranging the second spring 97, the connecting plate 94 is elastically squeezed. By rotating the bidirectional screw 95, the pressing plate 96 makes a threaded movement, thereby squeezing the connecting plate 94 by the second spring 97, and further moving the clamping block 93 to contact the driven rim 4 and the driving rim 5, squeezing and locking and limiting the driven rim 4 and the driving rim 5, so that the maximum distance between the driven rim 4 and the driving rim 5 is limited after being locked.

[0029] The usage state of the present invention is as follows: during use, the driving motor 1 rotates through the synchronous belt pulley to drive the lead screw to rotate, thereby realizing the forward movement of the support moving frame 2 and clamping the tire. The forward distance is adjusted according to different tires to clamp tires of different specifications. After clamping, the tire is inflated. The tire is inflated through the inflation pipe 7. At the same time, during the nailing process, there is pressure detection, and two small solenoid valves are externally connected to achieve small-range inflation and pressure relief to ensure the state of the tire. The rotating reducer 3 motor drives the reducer to drive the rotation of the active rim 5, thereby driving the rotation of the driven wheel. At the same time, after inflation, there is a check cylinder 6 on the left. After the cylinder extends, it is inserted into the wheel disc check port to prevent the rim from opening. Then, the moving clamp block 93 moves to the outside of the driven rim 4 and the active rim 5. Then, the bidirectional screw 95 is rotated. The rotation of the bidirectional screw 95 and the pressing plate 96 perform a threaded movement, thereby causing the pressing plate 96 to move. The pressing plate 96 presses the second spring 97, causing the second spring 97 to press the connecting plate 94, thereby causing the clamp block 93 to move into contact with the driven rim 4 and the active rim 5, and squeezing, locking, and limiting the driven rim 4 and the active rim 5, so that the maximum distance between the driven rim 4 and the active rim 5 after being locked is limited. Then, the screw ring 85 is rotated. The rotation of the screw ring 85 and the inflation pipe 7 perform a threaded movement, thereby causing the screw ring 85 to move. Furthermore, the sliding pin 83 moves. The sliding pin 83 drives the plug 82 to move. The distance between the plug 82 and the retaining ring 81 becomes larger. Furthermore, gas can push the baffle 810 through the gap between the retaining ring 81 and the plug 82, causing the baffle 810 to disengage from the inflation pipe 7. The movement of the baffle 810 presses the second spring 97, causing the second spring 97 to be compressed. When the inflation is completed, the second spring 97 resets, causing the baffle 810 to be pressed tightly against the end of the inflation pipe 7. By rotating the screw ring 85 and the inflation pipe 7 to perform a threaded movement, the distance between the plug 82 and the retaining ring 81 changes, thereby changing the air intake speed of the inflation pipe 7, avoiding the tire from bursting due to too fast inflation speed. At the same time, the baffle 810 is elastically pressed on the driven rim 4 by the compression spring 816, so that no air leakage occurs after the inflation is completed.
