Description

Technical Field

[0001] This utility model relates to the field of bushing press-fitting technology, and in particular to a height detection device for press-fitting rear subframe bushings of automobiles. Background Technology

[0002] The height detection device for pressing automotive rear subframe bushings is a specialized piece of equipment used to inspect the height dimension of automotive subframe bushings after pressing. This type of device plays a crucial role in the automotive manufacturing process, ensuring that the bushing pressing quality meets technical requirements.

[0003] According to Chinese Announcement No. CN223538996U, a portable object detection device based on infrared emission and reception is provided. The device includes a power socket, a power switch, an AC / DC power module, a DC / DC power module, and an infrared detection circuit module on its frame. The infrared emitting and receiving diodes of the infrared detection circuit module are arranged side-by-side facing outwards from the frame. The power switch is connected between the AC / DC power module and the power socket. The AC / DC power module is connected to AC mains power through the power switch and the power socket, converting AC mains power into DC power. The output of the AC / DC power module is connected to the input of the DC / DC power module. The output of the DC / DC power module is connected to the power input of the infrared detection circuit module, providing power to the infrared detection circuit module. This invention eliminates the need for opposing infrared emitting and receiving diodes in detection applications, improving the efficiency of object detection.

[0004] To ensure that the bushing does not block the infrared light of the detection component after being pressed into the designated position, and to facilitate the transmission and reception of infrared light, the infrared light cannot be received when the bushing is not in the designated position, thus issuing a warning. When the infrared transmitter and receiver are working, the lens is easily blocked by dust, which reduces the transmittance of infrared light and affects the accuracy of infrared transmission and reception.

[0026] Example 1:

[0027] Reference Figures 1-4 A height detection device for pressing a rear subframe bushing of an automobile includes: a workbench 1, a detection component 2, a linkage rotating structure 3, and a disassembly cleaning structure 4.

[0028] A pressing component is provided at the center of the upper part of the workbench 1, the detection component 2 is provided at both ends of the workbench 1, the linkage rotating structure 3 is provided on the outer wall of the back of the workbench 1, and the disassembly cleaning structure 4 is provided on the two sets of No. 1 shafts 301.

[0029] The detection component 2 on the workbench 1 can confirm whether the bushing is installed in the designated position. In order to provide normal cleaning of the detection component 2, the detachable cleaning structure 4 can be quickly installed and subsequently disassembled and replaced with the help of tools. The detachable cleaning structure 4 is attached to the surface of the detection component 2 for rotation cleaning through the linkage rotating structure 3.

[0030] Example 2:

[0031] Reference Figures 1-4 A height detection device for pressing a rear subframe bushing of an automobile includes: a detection component 2;

[0032] The detection component 2 includes two sets of fixing plates 201 disposed on both sides of the outer wall of the workbench 1. An infrared transmitter 202 and an infrared receiver 203 are respectively disposed in the two sets of fixing plates 201.

[0033] The fixing plate 201 can fix the infrared transmitter 202 and the infrared receiver 203 at a designated position on the workbench 1, and the signal emitted by the infrared transmitter 202 can be received by the infrared receiver 203.

[0034] Example 3:

[0035] Reference Figures 1-4 A height detection device for pressing a rear subframe bushing of an automobile includes: a linkage rotating structure 3;

[0036] The linkage rotary structure 3 includes a first shaft 301 rotatably mounted within two sets of fixed plates 201, a fixed seat 302 mounted on the outer wall of the back of the worktable 1, a bearing inside the fixed seat 302, a second shaft 303 mounted within the bearing of the fixed seat 302, pulleys 304 mounted at both ends of the second shaft 303 and on the first shaft 301, a wide belt 305 mounted on the pulleys 304 outside the second shaft 303 and the first shaft 301, a servo motor 306 mounted on the outer wall of the back of the worktable 1, a connecting shaft mounted on the output end of the servo motor 306, a first gear block 307 and a second gear block 308 mounted on the connecting shaft of the second shaft 303 and the servo motor 306 respectively, and the first gear block 307 and the second gear block 308 meshing with each other.

[0037] The servo motor 306 drives the second gear block 308 connected to the output shaft to rotate. Because the second gear block 308 meshes with the first gear block 307, the second shaft 303 connected to the first gear block 307 rotates stably in the bearing of the fixed seat 302. Since both the first shaft 301 in the fixed plate 201 and the second shaft 303 in the fixed seat 302 are equipped with pulleys 304, and the two sets of pulleys 304 are connected by a wide belt 305, the first shaft 301 in the fixed plate 201 will rotate stably.

[0038] Example 4:

[0039] Reference Figures 1-4 A height detection device for pressing a rear subframe bushing of an automobile includes: a detachable cleaning structure 4;

[0040] The detachable cleaning structure 4 includes a mounting block 401 mounted on a first shaft 301. The mounting block 401 has an insertion groove 402. A cleaning block 403 is inserted into the insertion groove 402. Holes 404 are provided on both sides of the inner wall of the insertion groove 402 and on the outer wall of the cleaning block 403. An elastic locking block 405 is slidably inserted into the hole 404.

[0041] The cleaning block 403 is inserted into the insertion slot 402 of the mounting block 401. At this time, the elastic locking block 405 is inserted into the hole 404 of the insertion slot 402 and the cleaning block 403, providing a connection between the cleaning block 403 and the mounting block 401. The mounting block 401 is connected to the first shaft 301, so that they rotate synchronously. This allows the cleaning block 403 to be attached to the lens of the infrared transmitter 202 and the infrared receiver 203 for cleaning. The infrared transmitter 202 and the infrared receiver 203 are existing mature technologies. Refer to the infrared anti-collision protection device for radiotherapy equipment pointed out in Chinese announcement number: CN213667594U.

[0042] Working principle:

[0043] Step 1, Signal Transmission and Detection Stage:

[0044] After the pressing equipment on workbench 1 completes the pressing of the bushing, it emits an infrared signal through infrared transmitter 202. Because the signal emitted by infrared transmitter 202 is at a slightly higher position after the bushing is pressed to the designated position, the signal emitted by infrared transmitter 202 can be received by infrared receiver 203. When the bushing is not pressed to the designated position, the bushing will block the signal emitted by infrared transmitter 202, causing infrared receiver 203 to not receive the signal. This allows personnel to quickly understand whether the bushing meets the requirements after pressing.

[0045] Step 2, First set of linked rotation stage:

[0046] During operation, the servo motor 306 provides a second gear block 308 on the output end to achieve continuous rotation through the shaft. The first gear block 307 on the second shaft 303 meshes with the second gear block 308, so the first gear block 307 rotates synchronously. The second shaft 303 connected to the first gear block 307 can achieve stable and continuous rotation inside the fixed base 302 synchronously.

[0047] Step 3, Second set of linked rotation stage:

[0048] Because the two sets of pulleys 304 can rotate synchronously through a set of wide belts 305 externally fitted, at this time, both ends of the second shaft 303 and the two sets of first shafts 301 are equipped with pulleys 304. During the rotation of the second shaft 303, it can synchronously drive the two sets of first shafts 301 to rotate synchronously and continuously. Moreover, because the first shaft 301 is located in the bearing of the fixed plate 201, stability can be guaranteed during the rotation.

[0049] Step 4, Installation and Fixing Stage:

[0050] The bottom dimension of the cleaning block 403 is adapted to the internal space dimension of the insertion slot 402 of the mounting block 401, allowing the cleaning block 403 to slide into the insertion slot 402 and be limited. In order to fix the cleaning block 403 stably inside the insertion slot 402 and prevent it from falling off, since both the insertion slot 402 and the cleaning block 403 are provided with holes 404, the elastic locking block 405 is slid into the insertion slot 402 and the holes 404 of the cleaning block 403. Through the shape of the elastic locking block 405 itself, it can be deformed to achieve stable fixation inside the two sets of holes 404, providing a connection and fixation between the cleaning block 403 and the mounting block 401. This method can be used without tools to quickly fix and subsequently disassemble through deformation and engagement.

[0051] Step 5, Rotation Cleaning Stage:

[0052] When the first axis 301 rotates, because the mounting block 401 is connected to the first axis 301, the mounting block 401 is fixed to the cleaning block 403 by plugging it in. At this time, the first axis 301 drives the mounting block 401 and the cleaning block 403 to rotate continuously together. Because the two sets of cleaning blocks 403 are respectively located on the surface of the infrared transmitter 202 and the infrared receiver 203 lens, synchronous lens cleaning can be achieved during synchronous rotation.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
