Description

Technical Field

[0001] The utility model relates to the technical field of tire processing, in particular to a clamping machine for processing an all-steel radial tire. Background Art

[0002] Tires are ground-contacting and rolling annular elastic rubber products installed on various vehicles or machinery. They are usually installed on metal rims, which can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance; general engineering tires need to be positioned during the processing process, but the general positioning and fixing device has a complex structure and is difficult to operate. The weight of engineering tires is very large, and the traditional clamping method is time-consuming and labor-intensive, not very practical, and not highly automated.

[0003] A Chinese patent with announcement number CN219685229U discloses a clamping machine for processing all-steel load-bearing radial tires, including a clamping machine body: a plurality of hydraulic cylinders are fixedly provided on both sides of the inner upper end of the clamping machine body, a lifting plate is provided at the lower end of the hydraulic cylinder, a sliding rod is fixedly provided at the lower end of the lifting plate, and sliding sleeves are provided on both sides of the sliding rod.

[0004] The clamping machine for processing all-steel load-bearing radial tires described in the above patent can automatically clamp, lift and rotate the tires when in use, making the tire detection process more efficient. However, when the tire is placed in the clamping machine before clamping, there is no limiting mechanism around the tire, which causes the tire to easily fall over due to unstable placement before clamping. At this time, the tire needs to be manually stabilized again before it can be further clamped and fixed, resulting in the entire clamping process of the tire being more cumbersome and the clamping efficiency being relatively low. At the same time, since the workers need to place the tires in the clamping machine when placing the tires, and the operating space in the clamping machine is small, there is a safety hazard that the workers are easily injured by bumps when placing the tires. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The technical problem to be solved by the utility model is to provide a clamping machine for processing all-steel radial tires, which can pre-clamp and limit the tire before clamping detection and realize convenient placement of the tire outside the clamping machine, thereby avoiding the situation where workers are bumped and injured due to the small operating space in the clamping machine when placing the tire.

[0007] (II) Technical solution

[0008] The utility model is realized through the following technical solutions: The utility model provides a clamping machine for processing all-steel radial tires, which includes a frame. A sliding mechanism is installed at the inner bottom end of the frame, and a pre-limiting mechanism is installed on the sliding mechanism. The sliding mechanism includes a U-shaped installation groove opened in the middle of the inner bottom end of the frame, a screw installed in the middle of the installation groove, a moving base installed on the screw, and a driving motor installed on the outer wall of the frame opposite to the screw. The pre-limiting mechanism includes a placement groove opened in the middle of the upper end of the moving base, vertical plates symmetrically installed on both sides of the upper end of the moving base, an electric push rod installed in the middle of one side wall of the vertical plate, and a clamping plate installed on the telescopic part of the electric push rod.

[0009] Further, the screw is rotatably connected to the installation groove, and the screw is connected to the driving motor through a coupling.

[0010] By adopting the above technical solution, the driving motor drives the screw to rotate, and under the action of screw transmission, the moving base can slide relative to the installation groove.

[0011] Further, the moving base is slidably connected to the installation groove, and a threaded hole is opened on the moving base opposite to the screw.

[0012] By adopting the above technical solution, it can ensure the stable sliding of the moving base relative to the installation groove.

[0013] Further, the fixed part of the electric push rod is bolted to the vertical plate, and the telescopic part of the electric push rod is bolted to the clamping plate.

[0014] By adopting the above technical solution, when the electric telescopic rod drives the clamping plate to move and clamp the tire before detection, pre-limiting and fixing of the tire can be realized.

[0015] Further, a lifting and clamping mechanism is installed on the upper side inside the frame. The lifting and clamping mechanism includes electric telescopic rods symmetrically installed on both sides of the inner top end of the frame, a mounting plate installed on the telescopic parts of the electric telescopic rods, guiding grooves opened at both ends of the inner part of the frame where the mounting plate is located, a bidirectional electric slide rail installed in the middle of the bottom end of the mounting plate, a hanging plate installed on two self-contained sliding blocks on the bidirectional electric slide rail. There are two hanging plates. A tightening shaft is installed on one hanging plate, and a tightening sleeve is installed on the other hanging plate. A rotating motor is installed on the hanging plate on one side of the tightening sleeve.

[0016] By adopting the above technical solution, when clamping and fixing the tire with the lifting and clamping mechanism, the jacking shaft and the jacking sleeve are first lowered to the height where the center of the tire is located under the action of the electric telescopic rod, and then the jacking shaft and the jacking sleeve are simultaneously moved closer to the center position of the tire under the action of the bidirectional electric slide rail until the jacking sleeve and the jacking shaft respectively contact the two side surfaces of the tire, thus realizing the clamping of the tire. After the tire is clamped, it is lifted to a specified height by the electric telescopic rod, and then the clamped tire is rotated only under the action of the rotating motor to detect the tire.

[0017] Further, the jacking sleeve and the jacking shaft are respectively rotatably connected to the corresponding hanging plates. The outer sides of the jacking shaft and the jacking sleeve are each provided with a limiting ring, and the side of the jacking sleeve facing the jacking shaft is an open structure.

[0018] By adopting the above technical solution, when clamping the tire, the jacking shaft can be inserted into the jacking sleeve to ensure that the side surface of the tire can contact the outer walls of the jacking shaft and the jacking sleeve.

[0019] Further, an operation panel is also installed in the middle of one side wall of the frame, and two vertical plates are symmetrically welded on both sides of the bottom end of the frame.

[0020] By adopting the above technical solution, the vertical plates can make the bottom end of the frame have a certain height to facilitate the reasonable installation of the driving motor.

[0021] (III) Beneficial effects

[0022] The utility model has the following beneficial effects compared with the prior art:

[0023] In order to solve the problem that although the existing clamping machine for processing all-steel radial tires can realize the automatic clamping, lifting and rotation of tires during use, making the tire detection process more efficient, when the tire is placed in the clamping machine before clamping, due to the absence of a limiting mechanism around the tire, the tire is prone to tipping over due to unstable placement before clamping. At this time, it is necessary for workers to manually place the tire stably again before further clamping and fixing the tire, resulting in a cumbersome clamping process for the tire and a low clamping efficiency. At the same time, since workers need to place the tire in the clamping machine when placing the tire, and the operable space in the clamping machine is small, there is a potential safety hazard that workers are prone to bump and get injured when placing the tire. The utility model installs a sliding mechanism and a pre-limiting mechanism at the bottom end inside the frame. On the one hand, it can realize the pre-clamping and limiting of the tire before clamping and detection under the action of the placement groove, clamping plate and electric push rod in the pre-limiting mechanism, prevent the accidental tipping of the tire during clamping before detection, and make the clamping and fixing efficiency of the tire higher after placement. On the other hand, through the driving motor and screw in the sliding mechanism, the moving base is moved to the outside of the frame, making the operable space for placing the tire larger, avoiding the situation where workers bump and get injured by the parts inside the clamping machine, and making the placement of the tire safer.

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the following further details the utility model with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0029] AsFigure 1 - Figure 2 As shown in the figure, a clamping machine for the processing of all-steel radial tires in this embodiment includes a frame 2. A sliding mechanism 5 is installed at the bottom end inside the frame 2, and a pre-limiting mechanism 6 is installed on the sliding mechanism 5. The sliding mechanism 5 includes a U-shaped installation groove 502 opened in the middle of the bottom end inside the frame 2, a screw rod 501 installed in the middle of the installation groove 502, a moving base 503 installed on the screw rod 501, and a driving motor 504 installed on the outer wall of the frame 2 opposite to the screw rod 501. The pre-limiting mechanism 6 includes a placement groove 602 opened in the middle of the upper end of the moving base 503, vertical plates 603 symmetrically installed on both sides of the upper end of the moving base 503, an electric push rod 604 installed in the middle of one side wall of the vertical plate 603, and a clamping plate 601 installed on the telescopic part of the electric push rod 604. The driving motor 504 drives the screw rod 501 to rotate, and under the action of screw transmission, the moving base 503 can slide relative to the installation groove 502, so as to facilitate the placement of the tire after the moving base 503 slides out of the frame 2. When the electric telescopic rod 102 drives the clamping plate 601 to move to clamp the tire before detection, the pre-limiting and fixing of the tire can be realized.

[0030] As Figure 1 - Figure 2 shown in the figure, in this embodiment, the screw rod 501 is rotatably connected to the installation groove 502, and the screw rod 501 is connected to the driving motor 504 by a coupling. The moving base 503 is slidably connected to the installation groove 502. A screw hole is opened on the moving base 503 opposite to the screw rod 501, which can ensure the stable sliding of the moving base 503 relative to the installation groove 502. The fixed part of the electric push rod 604 is bolted to the vertical plate 603, and the telescopic part of the electric push rod 604 is bolted to the clamping plate 601.

[0031] As Figure 1 - Figure 2As shown in the figure, in this embodiment, a lifting clamping mechanism 1 is installed on the upper side inside the frame 2. The lifting clamping mechanism 1 includes electric telescopic rods 102 symmetrically installed on both sides of the top end inside the frame 2, a mounting plate 101 installed on the telescopic part of the electric telescopic rods 102, guiding grooves 103 opened at both ends of the mounting plate 101 inside the frame 2, a bidirectional electric slide rail 104 installed in the middle of the bottom end of the mounting plate 101, and a hanging plate 108 installed on two self - contained sliding blocks on the bidirectional electric slide rail 104. There are two hanging plates 108. A tightening shaft 105 is installed on one of the hanging plates 108, and a tightening sleeve 107 is installed on the other hanging plate 108. A rotating motor 106 is installed on the hanging plate 108 on one side of the tightening sleeve 107. When using the lifting clamping mechanism 1 to clamp and fix the tire, first, under the action of the electric telescopic rods 102, the tightening shaft 105 and the tightening sleeve 107 are lowered to the height where the center of the tire is located. Then, under the action of the bidirectional electric slide rail 104, the tightening shaft 105 and the tightening sleeve 107 move towards the center position of the tire at the same time until the tightening sleeve 107 and the tightening shaft 105 respectively contact the two side surfaces of the tire, thus realizing the clamping of the tire. After the tire is clamped, it is lifted to a specified height by the electric telescopic rods 102. Then, by simply rotating the clamped tire under the action of the rotating motor 106, the tire can be detected.

[0032] As Figure 1 - Figure 2 shown in the figure, in this embodiment, the tightening sleeve 107 and the tightening shaft 105 are respectively rotatably connected to the corresponding hanging plates 108. Both the outer sides of the tightening shaft 105 and the tightening sleeve 107 are provided with limiting rings, and the side of the tightening sleeve 107 facing the tightening shaft 105 is an open structure, which can ensure that when clamping the tire, the tightening shaft 105 can be inserted into the tightening sleeve 107 to ensure that the side surface of the tire can contact the outer walls of the tightening shaft 105 and the tightening sleeve 107.

[0033] As Figure 1 - Figure 2 shown in the figure, in this embodiment, an operation panel 3 is also installed in the middle of one side wall of the frame 2. Two vertical plates 603 are symmetrically welded on both sides of the bottom end of the frame 2. The vertical plates 603 can make the bottom end of the frame 2 have a certain height to facilitate the reasonable installation of the driving motor 504.

[0034] The specific implementation process of this embodiment is as follows: Before clamping, first place the tire on the moving base 503, and pre-clamp and fix the tire under the action of the pre-limiting mechanism 6. Then, drive the screw 501 to rotate through the motor to move the moving base 503 into the frame 2. Next, just start the lifting and clamping mechanism 1, and the clamping of the tire can be achieved under the action of the tightening shaft 105 and the tightening sleeve 107 in the lifting and clamping mechanism 1. After clamping, the tire can be detected. When placing the tire before detection and clamping, by means of the placement groove 602, the clamping plate 601 and the electric push rod 604 in the pre-limiting mechanism 6, pre-clamping and limiting of the tire before clamping and detection can be realized, preventing accidental tipping of the tire during clamping before detection, making the clamping and fixing efficiency of the tire higher after placement. At the same time, through the drive motor 504 and the screw 501 in the sliding mechanism 5, the moving base 503 is moved to the outside of the frame 2, making the operable space larger when placing the tire, avoiding the situation of workers being bumped and injured by the parts inside the clamping machine, and making the tire safer when placed.
