[0005] The area where the inner tube is clamped in the inner tube processing and fixing equipment in the above scheme often becomes a blind spot for inspection and random testing. If a more complete inspection is required, the inner tube needs to be loosened and then re-positioned for clamping, which is not convenient for more comprehensive and rapid inspection of the inner tube. Summary of the invention

[0006] In order to overcome the existing deficiencies, the embodiment of the present application provides a high tear performance butyl inner tube processing equipment, which makes the inner tube clamping position flexible, reduces the detection of spot checks at the four corners due to obstruction of the clamping area, and makes the inner tube detection effect better.

DETAILED DESCRIPTION

[0024] The technical solution in the embodiment of the present application is to solve the problem that the inner tube in the above solution is difficult to flexibly clamp to reduce the blind spots of the inspection. The overall idea is as follows:

[0025] Embodiment 1:

[0026] like Figure 1 A high tearing performance butyl inner tube processing device is shown, comprising a detection platform 1 for placing the inner tube, and a rotary clamping mechanism 2:

[0027] The rotary clamping mechanism 2 includes a turntable member 21 rotatably arranged on the detection platform 1, on which a driving member 22 is arranged, and a pushing member 23 is installed at an equal angle on the outside of the driving member 22, and the outer ends of the pushing members 23 are connected to rolling clamping parts 24. Under the drive of the driving member 22, the pushing member 23 can push the rolling clamping parts 24 outward to clamp and fix the inner wall of the inner tube.

[0028] In this embodiment, the inner tube is placed on the inspection platform 1 in advance, and the rotary clamping mechanism 2 is placed in the inner ring of the inner tube. Then, under the drive of the driving member 22, the pushing member 23 can push the rolling clamping part 24 outward to clamp and fix the inner wall of the inner tube. During the inspection process, in order to detect the blind spots in the surface inspection, the inner tube is pressed to fix its position. With the coordinated design of the turntable member 21 and the rolling clamping part 24, the rotary clamping mechanism 2 is rotated to change the clamping and fixing position, thereby revealing the previously clamped and fixed position, thereby reducing the blind spots in the inner tube inspection.

[0029] like Figure 2 As shown, the turntable member 21 includes a bearing A211 embedded in the center of the detection platform 1, a rotating shaft A212 is fixed in the bearing A211, and a turntable 213 with an outer diameter smaller than that of the detection platform 1 is fixed on the top of the rotating shaft A212. Specifically, the turntable 213 can be rotated on the detection platform 1 by the cooperation of the rotating shaft A212 and the bearing A211, thereby assisting the rotation or position adjustment of the rotary clamping mechanism 2.

[0030] The detection platform 1 is provided with a through hole adapted to the bearing A211 and the rotating shaft A212. Specifically, the design of the through hole facilitates the installation of the bearing A211 and the rotating shaft A212, and indirectly assists the installation and fixation of the rotating disk 213.

[0031] The upper surface of the rotating shaft A212 is designed in an arc shape (not shown), and the height at the axis center is greater than the height at the edge. The rotating shaft A212 with an arc shape on the upper surface can facilitate the pushing operation of the pushing member 23.

[0032] like Figure 3 and Figure 4 As shown, the driving member 22 includes a servo motor 221 and a ball screw pair 222 installed at its output end, the outer wall of the ball screw pair 222 is provided with a screw nut 223 that can move along the displacement, and the end of the ball screw pair 222 is rotatably connected to the turntable 213, and support rods 25 are fixed on both sides of the outer wall of the servo motor 221, and the bottom ends of the support rods 25 are fixed to the upper surface of the turntable 213. Specifically, when the inner tube needs to be clamped, the servo motor 221 is started to make the screw nut 223 move down along the ball screw pair 222, thereby assisting the pusher 23 to be pushed outward.

[0033] It should also be noted that the servo motor 221 can be fixed on the turntable 213 by using the support rod 25 to increase the stability of the installation of the driving member 22 .

[0034] like Figure 4It is shown that all the pushers 23 are arranged at equal angles on the outer wall of the screw nut 223, and the pusher 23 includes a lug A231 fixed to the outer wall of the screw nut 223, a connecting rod A232 is hinged on the lug A231, a lug B233 is hinged at the bottom end of the connecting rod A232, a connecting rod B234 is fixed at the bottom of the lug B233, a rolling clamping part 24 is connected to the outer end of the connecting rod B234, and an inverted U-shaped guide frame 235 for the connecting rod B234 to penetrate is fixed on the outer edge of the upper surface of the turntable 213. Specifically, during the downward movement of the screw nut 223, the lug A231 connected thereto will move downward accordingly, indirectly increasing the angle formed by the connecting rod A232 and the ball screw pair 222, and at the same time causing the connecting rod B234 to move toward the outer side of the turntable 213 along the inverted U-shaped guide frame 235, thereby pushing the rolling clamping part 24 outward to clamp the inner tube.

[0035] like Figure 4 and Figure 5 The rolling clamping part 24 includes a support plate 241 connected to the outer end of the connecting rod B234 and perpendicular to the detection platform 1, and the upper and lower ends of the outer side of the support plate 241 are fixed with support ears C242, and the center holes of the two support ears C242 are embedded with bearings B243. A rotating shaft B244 is connected between the two bearings B243. The outer wall of the rotating shaft B244 is fixed with a cylinder 245 that can be pressed against the inner wall of the inner tube, and the outer wall of the lower support ear C242 is also fixed with a downwardly inclined triangular inclined plate 246 at the position facing the inner tube. Specifically, when the connecting rod B234 moves outward, the triangular inclined plate 246 can be inserted into the bottom of the inner tube and lifted to a certain height, and the cylinder 245 can be pressed against the inner wall of the inner tube, and the rotating shaft B244 can be rotated with the cooperation of the two bearings B243, thereby indirectly allowing the clamping position of the cylinder 245 to move in the inner tube clamping state.

[0036] It should also be noted that the specific size design of the triangular inclined plate 246 can be set according to the experience of personnel in the prior art field, and will not be repeated here.

[0037] An annular pad 3 is also fixed outside the bottom section of the detection platform 1, and the height of the annular pad 3 is higher than the height of the rotating shaft A212 exposed at the bottom of the detection platform 1. Specifically, the design of the annular pad 3 facilitates the support function.

[0038] When using this application:

[0039] The inner tube is placed on the detection platform 1 in advance, and the rotary clamping mechanism 2 is placed in the inner ring of the inner tube. When the inner tube needs to be clamped, the servo motor 221 is started to make the screw nut 223 move down along the ball screw pair 222, and the support ear A231 connected to the screw nut 223 will move down accordingly, indirectly increasing the angle formed by the connecting rod A232 and the ball screw pair 222, and at the same time making the connecting rod B234 move along the inverted U-shaped guide frame 235 toward the outside of the turntable 213. When the connecting rod B234 moves outward, the triangular inclined plate 246 can be inserted into the bottom of the inner tube and lifted to a certain height, exposing the bottom of the inner tube, and allowing the cylinder 245 to press against the inner wall of the inner tube. In order to detect blind spots in surface inspection, the inner tube is pressed to fix its position. With the coordinated design of the turntable 21 and the rotating shaft B244, the turntable 21 is rotated to change the clamping and fixing position of the inner tube, thereby exposing the previously clamped and fixed position, thereby reducing the blind spots in the inner tube inspection.

[0040] It should be noted that the specific model and specifications of the servo motor 221 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0041] The power supply and principle of the servo motor 221 are clear to those skilled in the art and will not be described in detail here.

[0042] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present application, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present application.
