Description

TECHNICAL FIELD

[0002] The automobile exhaust pipe support is a supporting component connecting the exhaust pipe and the chassis of the vehicle, and is usually used for fixing the exhaust system, absorbing vibration, allowing thermal expansion and contraction, and isolating noise, so as to ensure the stable operation of the exhaust system and the quietness in the vehicle.

[0003] In the production and quality inspection process of the U-shaped exhaust pipe support, the key parameters such as the curvature and diameter of the inner side surface need to be strictly detected to avoid the problem that the inner side surface of the support does not meet the standard, which leads to the fact that the exhaust pipe cannot be fully fitted with the outer wall of the exhaust pipe after assembly, and further causes the problems such as vibration, abnormal sound and even local stress concentration of the exhaust pipe during the driving of the vehicle. However, the existing detection means mostly adopts the point contact detection method, which can accurately obtain discrete data such as the local dimensional accuracy, shape accuracy and position accuracy of the inner side surface of the support, but cannot effectively evaluate the core indexes such as the surface profile, gap distribution and fitting rate of the curved surface, which reflect the overall fitting performance, resulting in the limitation of detection accuracy and the difficulty in ensuring the overall and close fitting of the support with the exhaust pipe. In addition, the U-shaped support needs to be rigidly connected with the vehicle body girder and other structural members through the mounting hole, and if the strength of the mounting hole is insufficient, the mounting hole will be deformed and cracked under the combined action of the weight of the exhaust pipe, the vibration load and the thermal stress for a long time, which will further weaken the hanging and supporting stability of the support for the exhaust pipe, and in severe cases, it will even cause safety hazards such as loosening and displacement of the exhaust pipe.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] Referring to Figures 1 to 6 , an automobile exhaust pipe support detection tool, comprising a mounting frame 1, a fixed detection plate 3 is fixedly connected above the mounting frame 1, a pair of mounting columns 9 are fixedly sleeved inside the fixed detection plate 3, a moving detection plate 4 with the same size as the fixed detection plate 3 is arranged on one side of the fixed detection plate 3, and an adjusting mechanism 2 for adjusting the detection mode is arranged above the mounting frame 1; The adjusting mechanism 2 comprises a reversible motor 201, the output end of the reversible motor 201 is fixedly connected with a transmission shaft 202, the surface of the reversible motor 201 is provided with a driving machine 5 for driving the reversible motor 201 to adjust the position, the surface of the transmission shaft 202 is fixedly connected with a pair of telescopic connecting plates 203, one end of the telescopic connecting plate 203 is detachably connected with an arc gauge 204, the surface of the transmission shaft 202 is detachably connected with a plurality of spherical gauges 205, the surface of the transmission shaft 202 is spline-connected with a pair of connecting sleeves 206, the surface of the connecting sleeve 206 is rotatably connected with a first telescopic push rod 207, and one end of the first telescopic push rod 207 is fixedly connected with the arc gauge 204.

[0020] The present application considers that when the inner side arc surface of the U-shaped support needs to be detected, the point contact detection method is usually used for detection, but the point contact cannot meet the detection requirements, and the face profile, gap distribution and fitting rate of the inner side arc surface of the U-shaped support cannot be detected, so that the detection range is reduced, and the U-shaped support after production cannot be accurately detected in all directions. Therefore, when the inner side arc surface of the U-shaped support needs to be detected, first, the mounting holes at both ends of the U-shaped support are aligned with a pair of mounting columns 9, and then the mounting holes are slid to the position of the fixed detection plate 3 until the outer side arc surface of the U-shaped support is fitted with the inner side arc surface of the fixed detection plate 3, then the moving detection plate 4 is driven to approach the position of the fixed detection plate 3 until the moving detection plate 4 and the fixed detection plate 3 are matched, at this time, the U-shaped support is located between the fixed detection plate 3 and the moving detection plate 4, the outer side arc surface of the U-shaped support is detected by the arc surface sensor arranged on the inner side arc surface of the fixed detection plate 3, and whether the outer side arc surface of the U-shaped support meets the requirements is judged. When the outer side arc surface of the U-shaped support meets the use requirements, and the mounting holes at both ends can be accurately sleeved on the surface of the pair of mounting columns 9, it is indicated that the size and position accuracy of the mounting hole meet the use requirements, at this time, the spherical gauge 205 is driven by the reversible transmission shaft 202, so that the spherical surface at one end of the spherical gauge 205 contacts with the inner side arc surface of the U-shaped support, then the transmission shaft 202 drives the spherical gauge 205 to reciprocate by 180° on the position of the inner side arc surface of the U-shaped support, so that the spherical gauge 205 fully contacts with the inner side arc surface of the U-shaped support, thereby detecting the size accuracy of the inner side arc surface of the U-shaped support. It should be noted that when the transmission shaft 202 drives the plurality of spherical gauges 205 to detect the precision of the inner side arc surface of the U-shaped support, if the U-shaped support meets the requirements at this time, the driving transmission shaft 202 drives the spherical gauges 205 and the arc gauges 204 to adjust the position, so that the arc gauges 204 are in the position of the outer side arc surface of the U-shaped support, and then the driving machine 5 is started to drive the arc gauges 204 below the forward and reverse motor 201 to move to the position of the inner side arc surface of the U-shaped support, until the arc surface of the arc gauges 204 is in contact with the inner side arc surface of the U-shaped support, and the arc surface sensor arranged on the surface of the arc gauges 204 is used to judge whether the circular arc degree of the inner side arc surface of the U-shaped support meets the requirements; It should be noted that before the position of the arc gauges 204 and the spherical gauges 205 is adjusted, the moving detection plate 4 needs to be separated from the fixed detection plate 3 first, and then the driving machine 5 is started to drive the forward and reverse motor 201 and the whole below to move away from the fixed detection plate 3 by a distance, at this time the forward and reverse motor 201 can adjust the position of the arc gauges 204 and the spherical gauges 205 during the movement, so that the arc surface of the arc gauges 204 can be in contact with the inner side arc surface of the U-shaped support in the subsequent state of transverse movement, and then the plurality of parameters of the inner side arc surface of the U-shaped support are detected, whether the U-shaped support meets the production requirements is judged by various sensors, the detection mode can be quickly switched, and the accuracy of the detection of the U-shaped support is improved; Moreover, after the arc surface of the arc gauges 204 is in contact with the inner side arc surface of the U-shaped support, at this time a pair of connecting sleeves 206 connected with the surface spline of the driving transmission shaft 202 moves relatively, the movement of the connecting sleeves 206 can exert extrusion force on the plurality of first telescopic push rods 207 rotatably connected with the surface, since one end of the first telescopic push rod 207 is telescopically arranged with the arc gauges 204, when the first telescopic push rod 207 is extruded to the limit position, the first telescopic push rod 207 will push the arc gauges 204 to press the inner side arc surface of the U-shaped support, so that the U-shaped support is subjected to a certain extrusion force, after a certain time of pressing, a pair of connecting sleeves 206 are driven to move reversely, so that the connecting sleeves 206 no longer exert extrusion force on the arc gauges 204 through the first telescopic push rods 207, but make the arc surface of the arc gauges 204 and the inner side arc surface of the U-shaped support again in the state of contact, the parameters of the inner side arc surface of the U-shaped support are detected again, whether the parameters of the inner side arc surface of the U-shaped support change is judged again by the arc surface sensor, whether the U-shaped support will be deformed after being subjected to a certain degree of extrusion force, and the like, so that the parameters of the U-shaped support can be detected in all directions, and the production quality of the U-shaped support is improved; It needs to be explained that when the first telescopic push rod 207 pushes the arc-shaped gauge 204 to exert extrusion force on the inner side arc surface of the U-shaped support, the end of the telescopic connecting plate 203 in contact with the arc-shaped gauge 204 will also be slightly telescopic, which can effectively avoid the situation that the arc-shaped gauge 204 is in an unbalanced state after the first telescopic push rod 207 exerts extrusion force on the arc-shaped gauge 204, thereby effectively improving the use strength of the arc-shaped gauge 204, and since the connecting sleeve 206 at one end of the first telescopic push rod 207 is in spline connection with the transmission shaft 202, the stability of the connecting sleeve 206 during upward and downward movement can be maximized, thereby stably transmitting the extrusion force to the first telescopic push rod 207, so that the arc-shaped gauge 204 can be subjected to uniform extrusion force, and the stability of the arc-shaped gauge 204 in use is improved.

[0021] With reference to Figures 4 to 6 The driving machine 5 is slidingly arranged above the mounting frame 1, a plurality of fixed columns 208 are fixedly connected above the connecting sleeve 206, the upper surfaces of the fixed columns 208 slidingly contact a laterally movable push frame 209, the contact surface of the push frame 209 and the fixed columns 208 is arranged obliquely, and one end of the push frame 209 is fixedly connected with a pair of contact rods 210 at the contact position of the fixed columns 208.

[0022] When the arc-shaped gauge 204 completes the parameter detection of the inner side arc surface of the U-shaped support for the first time, the laterally movable push frame 209 is driven to move close to the fixed detection plate 3, at this time, the movement of the push frame 209 drives the pair of contact rods 210 to move synchronously, since the contact position of the contact rods 210 and the fixed columns 208 is also arranged obliquely, the push frame 209 drives the pair of fixed columns 208 to move relatively through the contact rods 210, thereby driving the arc-shaped gauge 204 at one end of the first telescopic push rod 207 to perform strength detection on the inner side arc surface of the U-shaped support, and after the detection is completed, the parameter of the inner side arc surface of the U-shaped support is detected again through the sensor, which can effectively improve the accuracy of the detection of the U-shaped support and improve the detection range. It needs to be explained that when the arc-shaped gauge 204 is extruded by the first telescopic push rod 207, the forward and reverse motor 201 is in a state of no longer running, which can enable the first telescopic push rod 207 to sufficiently exert extrusion force on the arc-shaped gauge 204, and can ensure the uniformity of the extrusion force exerted by the arc-shaped gauge 204 on the U-shaped support. When the contact rod 210 at one end of the pushing frame 209 no longer exerts extrusion force on the fixed column 208, at this time, the reset spring arranged at the telescopic end of the first telescopic push rod 207 and the telescopic connecting plate 203 can make the arc-shaped testing fixture 204 reset, and then the first telescopic push rod 207 will transmit the reset force in the reverse direction to the connecting sleeve 206, so that the connecting sleeve 206 slides on the surface of the transmission shaft 202 again, so that the connecting sleeve 206 resets, which can facilitate subsequent compression detection of the U-shaped support, and can effectively improve the detection effect.

[0023] With reference to Figures 1 to 3 and Figure 11 One side of the fixed detection plate 3 is provided with a compression mechanism 6 for cooperating with the arc-shaped testing fixture 204 to compress and detect the U-shaped support, the compression mechanism 6 comprises an electric telescopic machine 601 fixedly installed above the mounting frame 1, the output end of the electric telescopic machine 601 is slidably connected with a telescopic rod 602, one end of the telescopic rod 602 is detachably connected with a compression plate 603, and the pushing frame 209 is fixedly connected with the telescopic rod 602.

[0024] When working, in order to avoid the case that the arc-shaped testing fixture 204 compresses and tests the U-shaped support, the inside arc surface of the U-shaped support is unevenly extruded, and the U-shaped support is damaged or deformed, therefore, after the arc-shaped testing fixture 204 completes the initial detection of the inside arc surface of the U-shaped support, that is, before the connecting sleeve 206 exerts extrusion force on the first telescopic push rod 207, at this time, the electric telescopic machine 601 is started to drive the telescopic rod 602 to move towards the outside arc surface of the U-shaped support, at this time, the telescopic rod 602 will drive the compression plate 603 to contact the outside arc surface of the U-shaped support, when the compression plate 603 is about to contact the outside arc surface of the U-shaped support, the telescopic rod 602 will drive the pushing frame 209 to move, at this time, the pushing frame 209 will slide with the fixed column 208 through the contact rod 210, and then drive the connecting sleeve 206 at one end of the fixed column 208 to slide on the surface of the transmission shaft 202, so that the compression plate 603 and the arc-shaped testing fixture 204 simultaneously and synchronously compress and test the inside and outside arc surfaces of the U-shaped support, so that the U-shaped support as a whole is subjected to uniform compression force, which can effectively improve the accuracy of the compression test of the U-shaped support, facilitate the subsequent detection of the arc-shaped testing fixture 204 on the inside arc surface parameters of the U-shaped support, and improve the accuracy of the detection of the inside arc surface and the outside arc surface of the U-shaped support; It should be noted that when the spherical gauge 205 is used to detect the size precision and other parameters of the inner side arc surface of the U-shaped support, at this time the electric telescopic machine 601 will not drive the pressing plate 603 to move through the telescopic rod 602, and when the driving machine 5 drives the forward and reverse motor 201 to reciprocate transversely above the mounting frame 1, since the upper and lower sides of the pushing frame 209 are telescopically arranged, at this time the movement of the forward and reverse motor 201 drives the upper and lower sides of the pushing frame 209 to also move transversely, so that the contact rod 210 at one end of the pushing frame 209 can always effectively contact the surface of the fixed column 208, which can effectively drive the connecting sleeve 206, thereby improving the stability of the driving of the connecting sleeve 206, so that the U-shaped support is subjected to uniform pressing force.

[0025] With reference to Figures 7 to 10 The inner side of the fixed detection plate 3 is provided with an auxiliary mechanism 7 for improving the detection stability of the U-shaped support at the position where the mounting column 9 penetrates, the auxiliary mechanism 7 includes a plurality of adjustable arc-shaped supporting plates 703 and a U-shaped clamping plate 701, the surface of the arc-shaped supporting plate 703 is fixedly connected with a matching rod 704, the inside of the fixed detection plate 3 is provided with an inclined groove 706, the matching rod 704 slides in the inside of the inclined groove 706, and the surface of the arc-shaped supporting plate 703 is rotatably connected with a rotating ring 705.

[0026] When the pushing frame 209 moves on the surface of the transmission shaft 202, at this time the pushing frame 209 also drives a plurality of arc-shaped supporting plates 703 to move to the position of the mounting hole of the U-shaped support, since the surface of the arc-shaped supporting plate 703 is fixedly provided with the matching rod 704, and the matching rod 704 slides in the inclined groove 706 provided in the inside of the fixed detection plate 3, at this time the matching rod 704 slides in the inclined groove 706, which is limited by the inclined groove 706, so as to swing around the rotating ring 705 during movement, realizing the movement form of swinging and sliding, when the arc-shaped supporting plate 703 moves to the specified position, at this time the arc-shaped supporting plate 703 will be attached to the mounting hole of the U-shaped support, since a plurality of arc-shaped supporting plates 703 are arranged in a conical shape, at this time the surfaces of the arc-shaped supporting plates 703 will be fully attached to the mounting hole of the U-shaped support, so that the U-shaped support is tightly fixed on the surface of the mounting column 9, which facilitates the subsequent pressing of the U-shaped support by the arc-shaped gauge 204 and the pressing plate 603, since the mounting hole is loose, which causes the U-shaped support to be subjected to uneven force, and can also effectively detect the strength of the mounting hole, whether the force of the mounting hole is changed after being expanded, and the force generated by the cooperation of the arc-shaped gauge 204 and the pressing plate 603, which can further improve the detection range of the U-shaped support, so that the U-shaped support can meet the use requirements; It should be noted that when the arc-shaped testing fixture 204 and the pressing plate 603 press the U-shaped support for testing, the arc-shaped supporting plate 703 will be opened in advance, clamped in the position of the U-shaped support mounting hole, so that the U-shaped support is fixed in advance, which can improve the stability of the U-shaped support pressing test, make the stress uniform, improve the accuracy of the test, and on the other hand, the strength of the U-shaped support mounting hole can be detected to determine whether the mounting hole meets the use requirements.

[0027] With reference to Figures 7 to 10 The auxiliary mechanism 7 further comprises a pair of push rods 702 in sliding connection with the fixed detection plate 3, the push rods 702 are in fixed connection with the U-shaped clamping plate 701, one end of the push rod 702 is in sliding contact with the inclined surface of the push frame 209, the side of the U-shaped clamping plate 701 close to the arc-shaped supporting plate 703 is provided in an inclined surface, and the arc-shaped supporting plate 703 is in sliding connection with the mounting column 9.

[0028] When the push frame 209 drives the contact rod 210 to exert a pressing force on the fixed column 208, the movement of the push frame 209 will drive the U-shaped clamping plate 701 at one end of the push rod 702 to slide inside the fixed detection plate 3, the sliding of the U-shaped clamping plate 701 inside the fixed detection plate 3 will drive the arc-shaped supporting plate 703 to move towards the position of the U-shaped support mounting hole through the inclined surface, and the arc-shaped supporting plate 703 will present a sliding and opening action until it is completely opened and tightly fitted with the inner side of the U-shaped support mounting hole, which can effectively limit the two ends of the U-shaped support and improve the stability of the detection; It should be noted that the arc-shaped supporting plate 703 is in a conical shape in the initial state, and only after the arc-shaped supporting plate 703 is subjected to the pressing force from the inclined surface of the U-shaped clamping plate 701, the arc-shaped supporting plate 703 will present a sliding and opening action on the surface of the mounting column 9, thereby fixing the U-shaped support mounting hole and effectively improving the stability of the U-shaped support detection; Moreover, the arc-shaped supporting plate 703 rotates around the rotating ring 705 when it is opened, and after the arc-shaped supporting plate 703 is opened, it is still in a conical shape in contact with the inner side of the mounting hole of the U-shaped support, which can make it fully contact with the mounting hole and improve the stability of the U-shaped support fixation.

[0029] With reference to Figures 7 to 10 The plurality of inclined grooves 706 inside the fixed detection plate 3 are mirror image arranged, the surface of the mounting column 9 is provided with a working groove, and the arc-shaped supporting plate 703 is arranged inside the working groove provided on the surface of the mounting column 9.

[0030] When the U-shaped clamping plate 701 moves the plurality of arc-shaped supporting plates 703 on the surface of the mounting column 9 by the inclined surface during work, in order to avoid the distance of the arc-shaped supporting plate 703 being too large during movement, the arc-shaped supporting plate 703 cannot be inserted into the mounting hole of the U-shaped support for expansion and fixing work. Therefore, by opening a working groove on the surface of the mounting column 9, when the arc-shaped supporting plate 703 is not inserted into the mounting hole of the U-shaped support during movement, the arc-shaped supporting plate 703 will only move within the diameter range of the working groove, thereby facilitating the subsequent stable and accurate insertion of the arc-shaped supporting plate 703 into the mounting hole. It should be noted that since the inclined groove 706 at one end of the matching rod 704 is mirror image arranged inside the fixed detection plate 3, when the arc-shaped supporting plate 703 moves to the position of the U-shaped support, the plurality of arc-shaped supporting plates 703 will only rotate along the rotating ring 705 and expand from the inside to the outside, and then fully contact the mounting hole of the U-shaped support for expansion and fixing work.

[0031] Referring to Figures 1 to 3 One side of the moving detection plate 4 is provided with a second telescopic push rod 8, which is fixedly arranged above the mounting frame 1. The lower side of the moving detection plate 4 is in sliding connection with the mounting frame 1, and the moving detection plate 4 is provided with a matching hole at the position of the mounting column 9, and the diameter of the matching hole is greater than the diameter of the mounting column 9.

[0032] During work, when the transmission shaft 202 drives the plurality of spherical detection tools 205 to detect the size precision of the inner arc surface of the U-shaped support, the detection parameters can be directly transmitted by the detection sensor according to the spherical surface of the spherical detection tool 205, and the inner arc surface of the U-shaped support can be quickly detected. When the arc-shaped detection tool 204 is switched to detect the arc degree of the inner arc surface of the U-shaped support, the second telescopic push rod 8 is started to drive the moving detection plate 4 to slide above the mounting frame 1, and then the driving machine 5 is started to drive the forward and reverse motor 201 to slide above the mounting frame 1, until the second telescopic push rod 8 drives the moving detection plate 4 to move away from the position of the arc-shaped detection tool 204, and then the forward and reverse motor 201 is started to drive the transmission shaft 202 to rotate, and the transmission shaft 202 drives the arc-shaped detection tool 204 and the spherical detection tool 205 to adjust the position, thereby performing surface contact detection work on the U-shaped support; It should be noted that when the moving detection plate 4 moves towards or away from the fixed detection plate 3, the mounting column 9 will be inserted into the mounting hole arranged in the moving detection plate 4, and when the fixed detection plate 3 and the moving detection plate 4 clamp the two ends of the U-shaped support, the arc-shaped detection tool 204 and the pressing plate 603 are started to press and detect the U-shaped support, which can further improve the stability of the U-shaped support during detection.

[0033] Referring to Figures 3 to 6The bottom of the mounting frame 1 is provided with a circular arc groove, the arc-shaped testing tool 204 and the pressing plate 603 are made of high-strength materials, the lower U-shaped clamping plate 701 is in sliding connection with the mounting frame 1, and the sliding position is provided with a reset spring.

[0034] During work, the circular arc groove provided at the bottom of the mounting frame 1 can avoid interference between the arc-shaped testing tool 204 and the spherical testing tool 205 during replacement operation and the mounting frame 1 or other components, so that the working efficiency of the equipment can be effectively improved. When the pushing frame 209 no longer pushes the positive and negative rotation motor 201 at one end of the transmission shaft 202 through the inclined surface, the positive and negative rotation motor 201 is reset under the action force of the reset spring, so that the telescopic connecting plate 203 below the positive and negative rotation motor 201 can be conveniently driven to fix the U-shaped support mounting hole next time, the stability of fixing the U-shaped support can be effectively improved, and the stability of the U-shaped support pressing detection is improved.
