Description

Technical Field

[0001] The present application relates to the technical field of inner tube quality detection, and in particular to an automobile inner tube detection device. Background Art

[0002] Automobile tires are one of the important parts of automobiles. They are in direct contact with the road surface and work together with the automobile suspension to mitigate the impact of the car when it is driving, ensuring that the car has good ride comfort and driving smoothness. Automobile tires are divided into tire rims, outer tires and inner tubes. The inner tube has a gas-containing cavity that expands after the gas is input to maintain the shape of the outer tire.

[0003] After the reproduction is completed, in order to ensure the safety during subsequent use, it is necessary to conduct random inspections on various performance indicators of the inner tube. The prior art discloses an outer diameter fluctuation detection device for the inner tube, which includes a fixed seat, a rotating disk, a rotating motor, and a displacement sensor. A circular hole is provided in the middle of the fixed seat, and a rotating motor is provided at the bottom end of the fixed seat. The rotating motor and the rotating disk are connected to each other. An outwardly protruding fixed block is provided on the fixed seat, and a fixing groove is provided in the middle of the fixed block. A movable rod is inserted in the fixing groove. A block is provided at the bottom of the movable rod. The width of the block is greater than the width of the fixing groove, so that the movable rod cannot penetrate the fixing groove as a whole. An external thread is provided at the bottom of the movable rod, and a fixing knob is installed on the movable rod. The fixing knob is provided with an internal thread. The fixing knob is inserted into the bottom of the movable rod from the top of the movable rod and installed at the bottom of the movable rod to cooperate with the external thread. A mounting hole is provided on the movable rod, and a displacement sensor is installed in the mounting hole.

[0004] With regard to the above-mentioned related technologies, the inflated inner tube is fixed by rotating the motor in conjunction with the outer convex block in the middle, and then a movable rod equipped with a displacement sensor is abutted against the outer circumference of the inner tube. During the rotation of the inner tube, the reading of the displacement sensor is used to determine whether the rubber distribution on the inner tube is uniform. However, only the outer circumference of the inner tube can be detected, and the inner circumference of the wheel body cannot be detected. Therefore, there is a missing area in the inspection of the uniformity of the rubber distribution of the inner tube. Summary of the invention

[0005] In order to more comprehensively detect the uniformity of rubber distribution of an automobile inner tube, the present application provides an automobile inner tube detection device.

[0006] The present application provides a vehicle inner tube detection device that adopts the following technical solution:

[0007] An automobile inner tube detection device, comprising:

[0008] Mounting frame;

[0009] A mounting half ring, the mounting half ring is connected to the mounting frame, and a locking half ring is movably connected to the mounting half ring;

[0010] A plurality of detection rods, the detection rods are slidably connected to the mounting half ring and the locking half ring, the plurality of detection rods are evenly distributed around the circumference and form a detection area for the inner tube to pass through, and a spring is sleeved and connected on the detection rods, the spring is connected to the mounting half ring or the locking half ring, and a displacement sensor is installed on the detection rods;

[0011] A plurality of drive units are used to drive the inner tube to rotate, the mounting half ring and the plurality of drive units are in the same concentric ring area, the drive units are connected to the mounting frame, and the drive units are connected to the inner tube.

[0012] By adopting the above technical solution, the inner tube is first placed in the installation semi-ring, and then the driving unit is connected to the inner tube, and then a proper amount of gas is filled into the inner tube to expand the inner tube, and then the driving unit applies force to the inner tube to make the inner tube rotate around its own axis. During the rotation of the inner tube, it passes through the detection area formed by multiple detection rods. Since the detection rods are in contact with the outer peripheral side of the inner tube, during the rotation of the inner tube, if there is uneven rubber distribution on the inner tube, and the outward deformation of the area with less rubber distribution increases, and the outward deformation of the area with more rubber distribution decreases, the pressure applied to the detection rod by the area with uneven rubber distribution is different, resulting in detection. The displacement of the measuring rod is different. By observing, recording and analyzing the detection data of multiple displacement sensors, it can be known whether the rubber on the inner tube is evenly distributed. The designed automobile inner tube detection device can realize the installation of the mounting half ring and the driving unit through the mounting frame, and a mounting base for installing the detection rod can be formed by the mounting half ring and the locking half ring.

The inner tube can be driven to rotate by the driving unit, so as to detect the uniformity of the rubber distribution in different areas of the inner tube.

[0013] In a specific implementation scheme, the driving unit includes:

[0014] An installation half frame, the installation half frame is connected to the installation frame, and a locking half frame is movably connected to the installation half frame;

[0015] Two driving wheels are respectively connected to the installation half frame and the locking half frame in rotation, the two driving wheels form a driving area for the inner tube to pass through, and the driving wheels can be connected to the inner tube in a rolling manner.

[0016] By adopting the above technical solution, a driving unit is designed, which can form an installation base for installing a driving wheel by installing a half frame and locking a half frame. The driving wheel can realize the rotation of the inner tube through friction, thereby completing the uniformity detection of the rubber distribution of the entire inner tube.

[0017] In a specific embodiment, the driving wheel comprises:

[0018] A hollow elastic connecting tube;

[0019] Two end plates are respectively connected to the axial ends of the elastic connecting tube, and the elastic connecting tube and the two end plates form a closed cavity. A rotating main shaft is coaxially connected to the end plate, and the rotating main shaft is rotatably connected to the installation half frame or the locking half frame.

[0020] By adopting the above technical solution, the designed driving wheel can form a flexible driving structure for driving the inner tube to rotate by rotating the main shaft, end plate and elastic connecting tube, and can adapt to inner tubes of different diameters by the degree of indentation of the elastic connecting tube.

[0021] In a specific embodiment, the mounting frame includes:

[0022] Fixed seat;

[0023] Two mounting bodies, the mounting bodies are connected to the fixing seats, the mounting half ring and the locking half ring are respectively mounted on the two mounting bodies, the mounting half frame and the locking half frame are respectively mounted on the two mounting bodies, and when the two mounting bodies move toward each other, the mounting half ring and the locking half ring can abut against each other, and the mounting half frame and the locking half frame can abut against each other.

[0024] By adopting the above technical solution, the designed mounting frame can facilitate the support of the two mounting bodies through the fixed seat. The two mounting bodies can cooperate to quickly splice and open the mounting half ring and the locking half ring, and can also quickly splice and open the mounting half frame and the locking half frame, thereby improving the efficiency of inner tube loading and unloading.

[0025] In a specific feasible implementation scheme, the mounting body is connected to an arcuate sliding rail, the mounting half frame is connected to a sliding block, the sliding block is slidably connected to the arcuate sliding rail, and the fixed seat is connected to a position adjustment unit, which is connected to the sliding block.

[0026] By adopting the above technical solution, the designed arc-shaped sliding rail and sliding block can cooperate to realize the position movement of the installation half frame, thereby changing the relative position between the installation half frame and the installation half ring. When it comes to inner tubes with different inner diameters, it can ensure the position stability of the inner tube during rotation and reduce the possibility of shaking of the inner tube.

[0027] In a specific feasible implementation scheme, a plurality of groups of one-way air suction holes are provided on the elastic connecting tube, and the plurality of one-way air suction holes in the same group are distributed along the axial direction of the rotating main shaft, an air pump is connected to the mounting frame, the rotating main shaft is hollow, and the air pump is connected to the inner cavity of the elastic connecting tube through an air pipe and the hollow rotating main shaft.

[0028] By adopting the above technical solution, after the rubber distribution uniformity test of the inner tube is completed, force is applied to the rotating main shaft, and the rotating main shaft drives the elastic connecting tube to rotate through the end plate, so that the one-way air suction hole on the elastic connecting tube is in contact with the outer surface of the inner tube. At this time, the air pump extracts the gas in the closed cavity surrounded by the elastic connecting tube and the two end plates, so that the elastic connecting tube and the inner tube are adsorbed and fixed. At this time, force is applied to the sliding block through the position adjustment unit, so that the two ends of the inner tube expand toward the detection area. At this time, the detection data of multiple displacement sensors are recorded and observed, and then the air pump is used to pump air into the closed cavity surrounded by the elastic connecting tube and the two end plates. Gas is input and then the rotating main shaft is driven to rotate, so that the one-way air suction hole on the elastic connecting tube is in contact with the outer surface of the inner tube again after rotating one circle, and the above-mentioned operation is repeated until the local compression deformation data of multiple areas on the inner tube are obtained. By comparing multiple groups of data, the uniformity of the deformation of the inner tube after local compression can be obtained. The designed air pump and the elastic connecting tube with a one-way air suction hole can, after the rubber distribution uniformity test of the inner tube is completed, realize the test of the uniformity of the deformation of the inner tube after local compression by controlling the working state of the air pump and the relative position relationship between the elastic connecting tube and the inner sleeve, and cooperating with the position adjustment unit.

[0033] In a specific possible implementation manner, the limiting frame is arranged in an arc shape, and an opening direction of the limiting frame is opposite to an opening direction of the arc-shaped sliding rail.

[0034] By adopting the above technical solution, the limit frame designed with an opening direction opposite to the opening direction of the arc-shaped sliding rail can reduce the sliding resistance between the sliding block and the limit frame during the process of driving the sliding block to move.

[0035] In a specific possible implementation manner, the fixing seat is connected to a containing groove, the top wall of the containing groove is provided with an opening, and the containing groove contains a leakage detection liquid.

[0036] By adopting the above technical scheme, the designed receiving groove can judge the air tightness of the inner tube by observing whether bubbles are generated by the leakage liquid in the receiving groove when testing the uniformity of deformation of the inner tube after local pressure. At this time, the elastic connecting tube drives the inner tube to move toward the detection area and expand, which can increase the gas pressure in other areas of the inner tube without additionally inflating the inner tube, thereby facilitating the detection and observation of the air tightness of the inner tube.

[0037] In a specific possible implementation manner, a water wiping strip is provided on the mounting body, and the water wiping strip can slide relative to the outer peripheral side of the inner tube.

[0038] By adopting the above technical solution, the designed water wiping strip can wipe off the moisture attached to the inner tube after completing the local air tightness test of the inner tube, thereby reducing the impact on the accuracy of the deformation uniformity test after the inner tube is locally compressed.

[0039] In summary, the present application includes at least one of the following beneficial technical effects:

[0040] 1. The designed automobile inner tube detection device can realize the installation of the mounting half ring and the driving unit through the mounting frame, and can form a mounting base for installing the detection rod through the mounting half ring and the locking half ring.

[0055] Reference Figure 3Specifically, the driving unit 3 includes an installation half frame 31, a locking half frame 32 and two driving wheels 33. The installation half frame 31 and the locking half frame 32 are respectively connected to the two installation bodies 12, and the installation half frame 31 and the locking half frame 32 can be spliced ​​to form a complete driving frame. The two driving wheels 33 are respectively rotatably connected to the installation half frame 31 and the locking half frame 32, and a driving area for the inner tube to pass through is formed between the two driving wheels 33. The driving wheel 33 can be rollingly connected to the inner tube, thereby allowing the inner tube to rotate around its own axis.

[0056] Reference Figure 4 Specifically, the driving wheel 33 includes an elastic connecting tube 331 and two end plates 332. The elastic connecting tube 331 is hollow, and the inner cavity of the elastic connecting tube 331 is filled with gas. The two end plates 332 are respectively bonded and fixed to the axial ends of the elastic connecting tube 331. The elastic connecting tube 331 and the two end plates 332 form a closed cavity.

[0058] Reference Figure 4Specifically, the elastic connecting tube 331 is provided with a plurality of groups of one-way air suction holes 3311. In the present application, the one-way air suction holes 3311 on the elastic connecting tube 331 are realized by means of a one-way valve, so that the gas in the elastic connecting tube 331 cannot be discharged to the outside through the one-way air suction holes 3311.

After the rubber distribution uniformity detection of the inner tube is completed, the uniformity of deformation of the inner tube after local compression can be detected by controlling the working state of the air pump 6 and the relative position relationship between the elastic connecting tube 331 and the inner sleeve, and cooperating with the position adjustment unit 5.

[0059] Reference Figure 5 Specifically, the position adjustment unit 5 includes a driving cylinder 51 and a limit frame 52. The driving cylinder 51 is bolted to the mounting body 12, and the piston rod of the driving cylinder 51 is arranged radially along the arc-shaped sliding rail 4. In this embodiment, the piston rod of the driving cylinder 51 is vertically arranged, the limit frame 52 is bolted to the piston rod of the driving cylinder 51, and a protrusion is formed on the sliding block 34, and an arc-shaped groove is opened on the arc-shaped sliding rail 4. The protrusion on the sliding block 34 passes through the arc-shaped groove and then extends into the limit frame 52. When the limit frame 52 is lifted or lowered under the drive of the driving cylinder 51, the protrusion will drive the sliding block 34 to slide in the arc-shaped sliding rail 4.

[0061] Reference Figure 6 In order to complete the air tightness test of the inner tube while conducting the local compression deformation uniformity test of the inner tube, a receiving groove 7 is bolted to the fixing seat 11, and an opening is set on the top wall of the receiving groove 7, and a leakage detection liquid is contained in the receiving groove 7. The receiving groove 7 is located between the two mounting bodies 12. The air tightness of the inner tube is judged by observing whether the leakage detection liquid in the receiving groove 7 generates bubbles, and at this time, the elastic connecting tube 331 drives the inner tube to move toward the detection area and expand, and the gas pressure in other areas of the inner tube can be increased without additionally inflating the inner tube, so as to facilitate the detection and observation of the air tightness of the inner tube. In this application, the leakage detection liquid is pure water. In order to reduce the influence of the pure water attached to the inner tube on the accuracy of the deformation uniformity test of the inner tube after local compression, a water wiping strip 8 made of a water-absorbing sponge material is fixedly connected to the mounting body 12, and the water wiping strip 8 can slide relative to the outer peripheral side of the inner tube.

[0062] The implementation principle of an automobile inner tube detection device in the embodiment of the present application is as follows: first, the inner tube is placed in the mounting half ring 2, and then the driving unit 3 is connected to the inner tube, and then a proper amount of gas is filled into the inner tube to expand the inner tube, and then the driving unit 3 applies force to the inner tube to make the inner tube rotate around its own axis. During the rotation of the inner tube, it passes through a detection area formed by a plurality of detection rods 22. Since the detection rods 22 are in contact with the outer peripheral side of the inner tube, during the rotation of the inner tube, if there is an uneven distribution of rubber on the inner tube, and the outward deformation of the area with less rubber distribution increases, and the outward deformation of the area with more rubber distribution decreases, the pressure applied to the detection rods 22 by the area with uneven rubber distribution is greater. Different forces lead to different displacements of the detection rod 22. By observing, recording and analyzing the detection data of multiple displacement sensors 24, it can be known whether the rubber on the inner tube is evenly distributed. The installation of the mounting half ring 2 and the drive unit 3 can be achieved through the mounting frame 1. The mounting half ring 2 and the locking half ring 21 can form a mounting base for installing the detection rod 22. A ring-shaped detection area for detecting the uniformity of the inner tube rubber distribution can be formed by multiple detection rods 22, springs 23 and displacement sensors 24, thereby more comprehensively detecting the uniformity of the rubber distribution of the automobile inner tube. The inner tube can be driven to rotate by the drive unit 3, so as to facilitate the rubber distribution uniformity detection of different areas of the inner tube.

[0063] After the rubber distribution uniformity test of the inner tube is completed, force is applied to the rotating main shaft 333, and the rotating main shaft 333 drives the elastic connecting tube 331 to rotate through the end plate 332, so that the one-way air suction hole 3311 on the elastic connecting tube 331 is in contact with the outer surface of the inner tube. At this time, the air pump 6 extracts the gas in the closed cavity surrounded by the elastic connecting tube 331 and the two end plates 332, so that the elastic connecting tube 331 is adsorbed and fixed to the inner tube. At this time, force is applied to the sliding block 34 through the position adjustment unit 5, so that the two ends of the inner tube expand toward the detection area. At this time, the detection data of the multiple displacement sensors 24 are recorded and observed, and then the elastic connecting tube 33 is supplied through the air pump 6. 1 and the closed cavity surrounded by the two end plates 332, and then the rotating main shaft 333 is driven to rotate, so that the one-way air suction hole 3311 on the elastic connecting tube 331 is in contact with the outer surface of the inner tube again after rotating one circle, and the above operation is repeated until the local compression deformation data of multiple areas on the inner tube are obtained, and the uniformity of the deformation of the inner tube after local compression can be obtained by comparing multiple groups of data; after the uniformity of the rubber distribution of the inner tube is detected, the uniformity of the deformation of the inner tube after local compression can be detected by controlling the working state of the air pump 6 and the relative position relationship between the elastic connecting tube 331 and the inner sleeve, and cooperating with the position adjustment unit 5.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
