Description

Technical Field

[0001] The utility model relates to the technical field of punching tools, in particular to a tire hole-punching device. Background Art

[0002] At present, a plurality of rubber tires are generally hung around small and medium-sized ships as cushions to achieve the effect of slowing down the collision of the hull. Among them, the rubber tires used need to be punched so that they are hung around the side of the ship through chains or wire ropes.

[0003] The hole punching process of rubber tires can be completed in the workshop or on-site. Among them, the workshop processing requires a vertical drilling machine with a special hole punching drill bit, and the transportation of the rubber tire becomes a problem. On-site processing mostly uses a hole opener to punch holes in rubber tires. However, on-site processing not only lacks a limiting mechanism to fix the rubber tire, which requires an additional person to stabilize the rubber tire, but also lacks a positioning mechanism for the movement of the hole opener, which leads to problems such as position offset and uneven size of the manual hole punching. Utility Model Content

[0004] In view of the above shortcomings, the utility model proposes a tire hole opening device, which can not only fix the tire by two clamping plates, but also achieve the positioning effect of the movement of the hole opener by adjusting the position of the mounting cylinder, so that the size and position of the holes opened on different tires on site can meet the requirements.

[0026] See also Figures 1 to 3 A tire hole-making device comprises: a screw rod 100 and a mounting assembly 200, wherein the screw rod 100 is extended in a vertical direction, and clamping plates 110 are movably provided at both ends of the screw rod 100, and the clamping plates 110 are used to abut against the end surface of the tire, and the screw rod 100 is threadedly connected with a first locking nut 120, and the first locking nut 120 is used to fix the position of the clamping plate 110; the mounting assembly 200 is movably provided on the screw rod 100, and the mounting assembly 200 is fixed to the screw rod 100 by a second locking nut 210, and the mounting assembly 200 is provided with a mounting cylinder 220, and the mounting cylinder 220 can move in a horizontal direction relative to the mounting assembly 200, and the mounting cylinder 220 is detachably provided with a hole opener 300, and the hole opener 300 is used to open a hole toward the side wall of the tire.

[0027] When using the tire hole opening device of the above structure, the tire is placed between the two clamping plates 110, and the first locking nut 120 is adjusted so that the two clamping plates 110 can clamp the tire, thereby achieving the effect of fixing the tire, and then the height of the mounting assembly 200 is adjusted according to the position of the desired hole opening, and the second locking nut 210 is adjusted to fix the position of the mounting assembly 200, so that the mounting cylinder 220 is aligned with the position of the desired hole opening, and finally the hole opener 300 is placed in the mounting cylinder 220, so that the hole opener 300 only moves horizontally, thereby achieving the positioning effect of the hole opener 300 movement. The above structure is not only conducive to avoiding the deviation existing in the manual fixing of tires in the past, but also can solve the problem of hole opening misalignment due to the lack of a positioning mechanism, thereby ensuring that the positions and sizes of multiple tire holes on site meet the required requirements.

[0028] See also Figures 1 to 3 Furthermore, the mounting assembly 200 includes two oppositely arranged flat plates 201, the flat plates 201 are provided with through holes for the screw rod 100 to be movably inserted, and a semi-circular plate 202 is connected to one side of each flat plate 201, and the two semi-circular plates 202 are spliced ​​into a circular cavity for the mounting cylinder 220 to be placed. Specifically, when in use, firstly according to the position of the hole required for the tire, the second locking nut 210 is rotated to change it, so that the two flat plates 201 are close to each other, so that the two semi-circular plates 202 are spliced ​​into a circular cavity, and then it is convenient for people to place the mounting cylinder 220 in the circular cavity.

[0029] See also Figures 1 to 3 Furthermore, two second locking nuts 210 are provided, and the flat plate 201 is clamped between the two second locking nuts 210. An adjusting gasket 230 is provided between the two flat plates 201, so that the gap between the two mounting plates can be changed by adjusting the gasket 230, which is beneficial to adjust the size of the circular cavity formed by the two semi-arc plates.

[0030] See also Figures 1 to 3 Furthermore, the clamping plate 110 located below the mounting assembly 200 is provided with a stopper 111, which is used to abut against the side wall of the platform on which the tire is placed, so that a positioning structure for placing the screw 100 is formed by the stopper 111, which is helpful to standardize the position where people place the screw 100. When the hole opener 300 opens a hole in the tire, the stopper 111 abuts against the platform to prevent the screw 100 from moving accordingly, thereby preventing the tire from moving and affecting the hole opening effect.

[0031] See also Figures 1 to 3 Further, the hole opener 300 includes a main body 310 built into the mounting barrel 220, the main body 310 is built into a motor, the output end of the motor is connected to a rotating rod 320, the rotating rod 320 is connected to a cutting piece 330, and the cutting piece 330 rotates to cut the side wall of the tire. Specifically, the motor drives the rotating rod 320 to rotate, the cutting piece 330 rotates to cut the side wall of the tire, and the cutting piece 330 moves the mounting barrel 220 so that the cutting piece 330 can penetrate into the tire to open a circular hole. It can be understood that the cutting piece 330 is provided with saw teeth on the side away from the mounting barrel 220, so that the efficiency of opening the tire hole is improved by the saw teeth.

[0032] See also Figures 1 to 3 Furthermore, the main body 310 is a cylindrical structure, and a plurality of elastic sheets 221 are distributed circumferentially inside the mounting tube 220, and the plurality of elastic sheets 221 can abut against the outer peripheral wall of the main body 310. Specifically, the plurality of elastic sheets 221 are bent by force and abut against the outer peripheral wall of the main body 310, so that the deformation of the elastic sheets 221 can achieve the effect of clamping the main body 310, and then the main body 310 is detachably mounted relative to the mounting tube 220, which is conducive to the subsequent disassembly of the hole opener 300. In some embodiments, the main body 310 can also be fixed to the mounting tube 220 by magnetic attraction, which will not be described in detail here.

[0033] Furthermore, the outer wall of the main body 310 is provided with scale lines, which are parallel to the axis of the installation tube 220, so that the depth of the main body 310 built into the installation tube 220 can be observed through the scale lines, which is also helpful for people to indirectly judge the displacement of the cutting member 330.

[0034] Furthermore, the plurality of elastic sheets 221 and the mounting tube 220 are integrally formed. Specifically, the mounting tube 220 can be made of plastic, and the plurality of elastic sheets 221 and the mounting tube 220 are integrally formed, which is not only conducive to reducing the weight of the mounting tube 220, but also conducive to improving the connection strength between the elastic sheets 221 and the mounting tube 220. In order to prevent the elastic sheets 221 from having a sharp tip and causing scratches on the main body 310, an arc transition surface is provided at one end of the elastic sheet 221 facing the center of the mounting tube 220.

[0035] See also Figures 1 to 3 Furthermore, the installation tube 220 is provided with a rod portion 222 for assisting pushing and pulling, and the rod portion 222 is arranged in a vertical direction, so that people can push the installation tube 220 to move through the rod portion 222, which is beneficial to improving people's use experience.
