Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, and in particular to a rapid detection device for tire vulcanization bladder damage. Background Technology

[0002] A vulcanizing bladder is an internal mold installed inside the tire during the vulcanization process to support and shape the tire. It is cylindrical and has retaining rings fixed at both ends along the axis. There is a through hole in the center of the retaining rings. It can affect the quality of the tire, so the bladder needs to be inspected regularly.

[0003] The prior art discloses a vulcanized capsule detection device (publication number: CN216206096U), including a main shaft system; a drive unit, including a rotary drive unit connected to the main shaft system and driving the main shaft system to rotate, and an adjusting unit connected to the main shaft system and driving the main shaft system to move laterally; a clamping part; the clamping part is installed on the main shaft system and is used to clamp the vulcanized capsule; a detection part; including several line laser sensors located on both sides and above the crown of the vulcanized capsule, for detecting the uniformity of the sides and crown of the vulcanized capsule.

[0004] In existing technologies, the surface of the capsule is mainly detected by multiple sensors on the support to determine whether the surface unevenness meets the standard. However, the position of the support is fixed and cannot be adjusted. This means that the detection positions of the multiple sensors on the support are fixed, and the multiple sensors detect the unevenness of the capsule at a fixed circumference position. The detection range and accuracy are not good, and there is room for optimization.

[0005] Therefore, we propose a rapid detection device for tire vulcanization bladder damage. Utility Model Content

[0008] The main body has a sliding seat on its top, and both the main body and the main body are fixedly mounted with a fixed seat.

[0009] A detection component is disposed on one side of the main body for detection. The detection component includes a support frame, an electric actuator, a support arm, and a detection head.

[0011] In a preferred embodiment of this utility model, the support frame is formed into an L-shaped bracket, and a circular hole is provided at the top of the support frame. The output shaft of the electric actuator extends through the circular hole to the bottom of the support frame.

[0017] Beneficial effects

[0018] This invention provides a rapid detection device for tire vulcanization bladder damage. It has the following beneficial effects:

[0019] 1. This rapid detection device for tire vulcanizing bladder damage uses multiple detection heads located below a support arm to inspect the circumferential surface of the bladder. Each detection head can be a line laser sensor. The device detects the degree of unevenness or runout on the bladder surface to determine if the bladder is flat, enabling rapid detection.

[0027] A rapid detection device for tire vulcanization bladder damage, such as Figure 1 and Figure 2 As shown, it includes:

[0028] The main body 10 has a sliding seat 12 slidably mounted on its top. Both the main body 10 and the main body 10 are fixedly mounted with fixed seats 11. Specifically, a push cylinder is fixedly mounted on the top of the main body 10. The sliding seat 12 is fixedly connected to the output shaft of the push rod. The sliding seat 12 pushes the fixed seat 11 closer to the other fixed seat 11. The two fixed seats 11 limit the end of the capsule. A motor is also fixedly mounted on one side of the sliding seat 12. A turntable is fixedly mounted on the output shaft of the motor. The fixed seat 11 of the sliding seat 12 is fixedly mounted on the turntable. The same turntable is fixedly mounted on the other side of the main body 10. The turntable mounted on the main body 10 is fixedly mounted with an air nozzle for inflating the capsule. The air nozzle is fixedly connected to a pressure gauge. The turntable on the sliding seat 12 is rotated by the motor, causing the capsule to rotate and thus be uniformly detected. The above is known prior art and will not be described in detail here.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the detection assembly is located on one side of the main body 10 for detection. The detection assembly includes a support frame 20, an electric actuator 21, a support arm 22, and a detection head 23. The support frame 20 is fixedly installed to the main body 10. The electric actuator 21 is fixedly installed on the top of the support frame 20. The support arm 22 is movably installed on the output shaft of the electric actuator 21. Several detection heads 23 distributed on the same plane are fixedly installed at the bottom of the support arm 22. The support frame 20 forms an L-shaped bracket. A circular hole is opened at the top of the support frame 20. The output shaft of the electric actuator 21 extends through the circular hole to the bottom of the support frame 20. The support arm 22 forms a rod with a U-shaped cross-section. At least three detection heads 23 are fixedly installed at the bottom of the support arm 22.

[0030] In this solution, the circumferential surface of the capsule is mainly detected by multiple detection heads 23 located below the support arm 22. The detection head 23 can be a line laser sensor. The detection head 23 detects the degree of unevenness and runout on the surface of the capsule to determine whether the capsule is flat, thus achieving rapid detection. The rotatable support arm 22 can adjust whether the multiple detection heads 23 are distributed along the circumference or the radial direction of the capsule, which has the function of multi-point detection of the capsule. Adjusting the detection position of the detection head 23 is convenient and quick, improving the comprehensiveness of the detection and making the detection results more accurate.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, the connection structure is set between the output shaft of the electric actuator 21 and the support arm 22 for adjusting the position of the support arm 22;

[0032] The detection assembly includes a rotating seat 30 and thrust holes 31. The rotating seat 30 is fixedly installed with the electric actuator 21 and rotatably connected to the support arm 22. Several thrust holes 31 are opened on the top of the rotating seat 30, and a screw is installed in the thrust hole 31. The rotating seat 30 forms a circular plate. The center of the top plate of the rotating seat 30 is fixedly connected to the output shaft of the electric actuator 21. The bottom of the rotating seat 30 is provided with an integrally formed cylinder. The center of the top of the support arm 22 is provided with a shaft hole, which is circumferentially rotated in the shaft hole. The thrust holes 31 are circular holes. Several identical thrust holes 31 are arranged in a circular array on the top of the rotating seat 30. The top of the support arm 22 is provided with a threaded hole, and bolts can pass through the thrust holes 31 and the threaded hole to lock the position of the rotating seat 30.

[0033] To achieve position adjustment and locking of the support arm 22, the support arm 22 is rotated around the cylinder at the bottom of the rotating seat 30. The screw is inserted into the rotating seat 30 at different positions and locked with the threaded hole at the top of the support arm 22 to fix the position of the support arm 22. Thus, the position of the detection head 23 at the bottom of the support arm 22 is fixed. Multiple detection heads 23 perform surface concavity and convexity detection on the rotating capsule. The operation is simple and flexible.

[0034] The working principle of this utility model is as follows: Rotate the support arm 22, which rotates around the cylinder at the bottom of the rotating seat 30. Insert the screw into the rotating seat 30 at different positions and lock it with the threaded hole at the top of the support arm 22 to fix the position of the support arm 22. Thus, the position of the detection head 23 at the bottom of the support arm 22 is fixed. The rotatable support arm 22 can adjust whether the multiple detection heads 23 are distributed along the circumference of the capsule or along the radial direction of the capsule, which has the function of multi-point detection of the capsule. The detection head 23 can be a line laser sensor. By detecting the degree of unevenness and movement on the surface of the capsule through the detection head 23, it is determined whether the capsule is flat. With the help of the pressure gauge on the air nozzle, the airtightness of the capsule is determined, so as to realize the rapid detection of the capsule.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
