[0041] A large bearing 15 is rotatably mounted on the base 1, and a placement disc 16 is fixedly connected to the inner ring of the large bearing 15, and a brake drum 14 is placed on the placement disc 16. An annular gear plate 19 is fixedly connected to the bottom of the placement disc 16. A motor 17 is fixedly connected to the left side of the bottom front of the base 1 through a mounting frame, and a second gear 18 used in conjunction with the annular gear plate 19 is fixedly connected to the output shaft of the motor 17. The design of the motor 17, the second gear 18 and the annular gear plate 19 facilitates the change of the overall angle of the placement disc 16, so that the brake drum 14 can be rotated as a whole when other tests are performed on the brake drum 14;

[0042] A first electric slide rail 9 is fixedly connected to the right side of the base 1, a first slide seat 10 is arranged in the first electric slide rail 9, an L-shaped docking plate 11 used in conjunction with the support plate 2 is fixedly connected to the first slide seat 10, a second electric slide rail 12 is horizontally embedded in the left side of the top of the support plate 2, a second slide seat 13 is arranged in the second electric slide rail 12, the front and back sides of the second slide seat 13 are fixedly connected to the sliding frame 3 through a fixed plate, the design of the first electric slide rail 9, the first slide seat 10, the second electric slide rail 12 and the second slide seat 13 can change the position of the support plate 2 and the sliding frame 3, so as to change the position of the first pressure sensor 6 and the indentation measuring head 8, so as to facilitate the measurement of the measuring point and the indentation as needed, and the sliding frame 3 can be removed from the brake drum 14 as a whole, so as to facilitate the removal of the brake drum 14 after detection;

[0043] An auxiliary component used in conjunction with the brake drum 14 is arranged on the placement disc 16, and a controller is embedded on the right side of the top front of the base 1. The design of the controller facilitates the control of the electronic components of the device.

[0044] like Figure 1-Figure 8 and Fig.10 As shown, the auxiliary component includes a square frame 20 embedded on the placement disc 16 and the square frame 20 is located in the brake drum 14. The top and bottom of the inner cavity of the square frame 20 are embedded with a cylinder 22. A piston rod 59 is slidably arranged in the cylinder 22. The end of the piston rod 59 close to each other is fixedly connected to a pressure plate 21 slidably arranged in the square frame 20. The piston rod 59 is in a T-shaped structure so as to divide the interior of the cylinder 22 into two air chambers.

[0045] Multiple sets of positioning rods are vertically inserted around the two sets of pressing plates 21 near each other, and the top and bottom ends of the multiple sets of positioning rods are fixedly connected to the top and bottom of the inner cavity of the square frame 20. The design of the positioning rods improves the overall stability of the pressing plates 21 when moving;

[0046] An air pump 23 is fixedly connected to the left side of the bottom of the placement disc 16, and the air outlet end of the air pump 23 is connected to a first three-way pipe 24. Two ends of the first three-way pipe 24 are connected to the outside of the top of the cylinder 22, and the inside of the top of the cylinder 22 is connected to a second three-way pipe 25. One end of the second three-way pipe 25 passes through the placement disc 16 and is connected to an end of the first three-way pipe 24 close to the air pump 23. The top and bottom of the left side of the front of each group of cylinders 22 are connected to a fixed pipe 26. The air pump 23 provides an air source, and with the assistance of the first three-way pipe 24 and the second three-way pipe 25, the gas can be filled into the cylinder 22, and the design of the fixed pipe 26 can facilitate exhaust.

[0047] The three ends of the first three-way pipe 24 and the second three-way pipe 25 are respectively provided with a first solenoid valve 27 and a second solenoid valve 28, and the fixed pipe 26 is provided with a third solenoid valve 29. The end of the second three-way pipe 25 close to the first three-way pipe 24 is located on the left side of one group of the first solenoid valves 27. The design of the three groups of solenoid valves facilitates the control of the opening and closing of the first three-way pipe 24, the second three-way pipe 25 and the fixed pipe 26, so as to freely control the up and down movement direction of the piston rod 59.

[0048] The auxiliary component also includes a driving plate 30 rotatably mounted around the pressure plate 21, and a push plate 31 is rotatably mounted on one end of the upper and lower driving plates 30 away from the pressure plate 21, and T-shaped rods 32 are inserted at the top and bottom of the push plates 31 close to each other, and a first spring 33 is wound around each group of T-shaped rods 32, and the two ends of the first spring 33 are fixedly connected to the side where the push plate 31 and the T-shaped rod 32 are close to each other, and the ends of the adjacent two groups of T-shaped rods 32 away from the square frame 20 are fixedly connected to the limiting plate 34, and the side of the limiting plate 34 away from each other is attached to the inner circle of the brake drum 14, and the elastic rebound of the first spring 33 is used to continuously give a certain driving force to the limiting plate 34, so that the limiting plate 34 can maintain a certain distance from the push plate 31 when not squeezed;

[0049] The limiting plate 34 is embedded with a second pressure sensor 35 used in conjunction with the push plate 31. The second pressure sensor 35 is used to detect the change in pressure so as to quickly know the contact between the limiting plate 34 and the push plate 31, thereby facilitating the timely closing of the air pump 23 to avoid excessive pushing and damage to the limiting plate 34. One end of the push plates 31 close to each other is fixedly connected to a multi-section telescopic rod 43, and one end of the multi-section telescopic rod 43 close to each other is fixedly connected to the square frame 20. Each group of multi-section telescopic rods 43 has at least four sections. The limitation on the number of sections of the multi-section telescopic rods 43 avoids too few sections of the multi-section telescopic rods 43, which makes it impossible to effectively position the push plate 31.

[0050] The top of each group of push plates 31 is symmetrically rotatably equipped with a mounting shaft 36, and the mounting shaft 36 is fixedly connected with a first gear 37 and a flip frame 38 from the inside to the outside in sequence. The limiting plate 34 is fixedly connected with an auxiliary toothed plate 39 used in conjunction with the first gear 37, and a fixed slide 58 is provided at the bottom of the auxiliary toothed plate 39. The push plate 31 is fixedly connected with a sliding bracket 57 used in conjunction with the fixed slide 58. The design of the fixed slide 58 and the sliding bracket 57 can slide and position the auxiliary toothed plate 39, thereby improving the overall stability of the auxiliary toothed plate 39.

[0051] Each set of flip frames 38 is symmetrically and slidably provided with slide rods 40, and the top and bottom ends of two adjacent sets of slide rods 40 are respectively fixedly connected with a top plate and a pressure block 42, and the bottom of the pressure block 42 is attached to the brake drum 14. A second spring 41 is wound around each set of slide rods 40, and both ends of the second spring 41 are fixedly connected to the side where the top plate and the flip frame 38 are close to each other. By setting auxiliary components and utilizing a variety of multi-directional positioning methods, the brake drum 14 can be quickly positioned, and the brake drum 14 can be effectively prevented from moving during the detection process, thereby improving the accuracy of the detection result. In addition, pneumatic drive is adopted throughout the process, and while ensuring the positioning effect, the brake drum 14 is flexibly pressed to avoid damage to the brake drum 14.

[0052] like Figure 1 , Figure 2 and Fig.11 As shown, in the prior art, when the brake drum 14 is tested for its pressure resistance, it is impossible to quickly and real-time purge the required test surface of the brake drum 14 according to the size of the brake drum 14, resulting in impurities attached to the brake drum 14. When the spherical pressure head moves downward, the impurities will be pressed down together, which will directly affect the depth of the indentation, and then directly affect the accuracy of the indentation measurement. A fixed track 45 is fixedly connected to the right side of the top of the placement disk 16, and a movable seat 46 is slidably arranged on the fixed track 45. A guide rod 47 is vertically inserted symmetrically along the left and right directions on the movable seat 46. The two ends of the guide rod 47 are fixedly connected to the top and bottom of the inner cavity of the fixed track 45. An auxiliary spring 48 is wound around the guide rod 47, and the two ends of the auxiliary spring 48 are fixedly connected to the bottom of the movable seat 46 and the bottom of the inner cavity of the fixed track 45. The elastic rebound of the auxiliary spring 48 is utilized to sustainably give a certain supporting force to the movable seat 46, so that the movable seat 46 can be maintained at a certain height when not in use.

[0053] The front side of the moving seat 46 is rotatably provided with a rotating shaft 49, and both ends of the rotating shaft 49 are respectively fixedly connected with a swing frame 50 and an auxiliary plate in the front and rear directions. The left side of the top of the front side of the fixed track 45 is fixedly connected with a blocking column used in conjunction with the swing frame 50, and the right side of the frame 5 is fixedly connected with a transverse guide plate 44 used in conjunction with the swing frame 50. The blocking column can control the swing angle of the swing frame 50 so that the swing frame 50 can move synchronously with the movement of the transverse guide plate 44.

[0054] One end of the first three-way pipe 24 close to the air pump 23 is connected to a docking pipe 53, on which a fourth solenoid valve 54 is arranged, and one end of the docking pipe 53 away from the air pump 23 passes through the placement disc 16 and is connected to a telescopic hose 55, a bend pipe 52 is transversely inserted in the swing frame 50, one end of the bend pipe 52 is connected to the telescopic hose 55, and the other end of the bend pipe 52 is connected to a main pipe 51 and the main pipe 51 is fixed on the swing frame 50, and the left side of the main pipe 51 is connected to multiple groups of oblique pipes in sequence along the front-to-back direction, and the design of the fourth solenoid valve 54 can control the opening and closing state of the docking pipe 53, so that when the main pipe 51 and the bend pipe 52 follow the swing frame 50 and the transverse guide plate 44 to move down to a certain height, the gas can be quickly transported to the oblique pipe, and the surface of the brake drum 14 can be quickly purged to avoid impurities affecting the detection accuracy;

[0055] A support plate is fixedly connected to the right side of the top back of the movable seat 46, and a plurality of sets of third springs 56 are fixedly connected in sequence on the upper edge of the auxiliary plate in the front-to-back direction and one end of the third spring 56 is fixedly connected to the support plate. A convex plate is fixedly connected to the left side of the bottom of the swing frame 50. The elastic rebound of the third spring 56 is utilized to make the swing frame 50 a movable structure, thereby preventing the protruding swing frame 50 from affecting the normal removal and placement of the brake drum 14.

[0056] Specifically, the working principle of the comprehensive inspection device for automobile parts is as follows: the user flips the swing frame 50 upward to make it flip to the right, and compresses the third spring 56. Then the user places the brake drum 14 on the placement disc 16. At this time, the square frame 20 is located inside the brake drum 14. At this time, the user releases the swing frame 50 and uses the elastic rebound of the third spring 56 to reset the swing frame 50, and at the same time, the blocking column positions the swing frame 50. Then the user turns on the air pump 23 through the controller, and turns on the first solenoid valve 27 and the third solenoid valve 29 on the corresponding two sets of fixed tubes 26 in the middle. At this time, the air pump 23 transports the external gas to the cylinder 22 through the first three-way pipe 24, thereby pushing the piston rod 59 to move inward synchronously, and the piston rod The gas on one side of 59 that is close to each other will be discharged through the two sets of fixed pipes 26 on the inner side. At the same time, the piston rod 59 drives the pressure plate 21 to move inward synchronously, and with the assistance of the movable driving plate 30, it can push multiple sets of push plates 31 and limit plates 34 to move in the opposite direction synchronously. At this time, the limit plate 34 will contact the inner ring of the brake drum 14 in advance until the push plate 31 contacts the second pressure sensor 35. At this time, the controller receives the change in pressure value, and it is determined that the push plate 31 and the limit plate 34 have quickly fixed the inner ring of the brake drum 14. At this time, the air pump 23 and the opening valve are closed, and under the elastic rebound of the first spring 33, a certain moving space can be given to the limit plate 34. When the second pressure sensor 35 contacts the push plate 31, the meshing of the first gear 37 and the auxiliary gear plate 39 is utilized. The turning frame 38 is driven to turn over exactly ninety degrees, and the elastic rebound of the second spring 41 is used to make the pressure block 42 close to the top of the brake drum 14, and the top of the brake drum 14 is simultaneously pressed and limited at multiple locations. At this time, a variety of multi-directional positioning methods are used to quickly position the brake drum 14, effectively avoiding the position movement of the brake drum 14 during the detection process, thereby improving the accuracy of the detection result. The pneumatic drive method is adopted throughout the process, and while ensuring the positioning effect, the brake drum 14 is flexibly pressed to avoid damage to the brake drum 14. With the assistance of the first solenoid valve 27, the second solenoid valve 28 and the third solenoid valve 29, the opening and closing states of the first three-way pipe 24, the second three-way pipe 25 and the fixed pipe 26 can be controlled to control the brake drum 14. The fixed state is controlled to facilitate fixing and releasing. Then the user turns on the first electric slide rail 9, thereby driving the first slide seat 10, the L-shaped docking plate 11 and the support plate 2 to move toward the front until the frame 5 is moved to the upper position of the brake drum 14 and the swing frame 50. At this time, the user turns on the cylinder 4 through the controller. At this time, the cylinder 4 drives the frame 5 to move downward, thereby synchronously driving the transverse guide plate 44 to move downward and pressing the swing frame 50. At this time, the swing frame 50 moves with the downward movement of the frame 5, thereby driving the main pipe 51 and the bend pipe 52 to move downward synchronously. When it drops to a certain height, there is a certain distance between the frame 5 and the brake drum 14. At this time, the fourth solenoid valve 54 is turned on, and the air pump 23 delivers the gas to the telescopic hose 55 through the docking pipe 53.And it is sprayed out through the main pipe 51 and the inclined pipe to quickly purge the surface of the brake drum 14, and quickly blow away the impurities on the surface of the brake drum 14. Then the user controls the box 5 to continue to move downward. At this time, the spherical pressure head will contact the brake drum 14 in advance. At this time, the pressure plate will continuously squeeze the first pressure sensor 6, thereby driving the spherical pressure head to press the brake drum 14 and leave an indentation. The first pressure sensor 6 records the pressure change. At the same time, the user controls the support plate 2 to move, moves the indentation measuring head 8 to the top of the indentation, and uses the electric push rod 7 to control the indentation measuring head 8 to move downward to detect the indentation. At the same time, the fixed brake drum 14 can also perform other detection work.
