Description

Technical Field

[0001] This application relates to the field of automotive braking system technology, and in particular to a detection device for the master cylinder piston cup of an HCU. Background Technology

[0002] Inspecting the piston cups inside the HCU master cylinder is a crucial step in ensuring a vehicle's braking capability in emergency situations. This involves checking for the piston cups' installation, correct orientation, and any missing or excess material to determine if the installation meets standards. Since the piston cups are installed in grooves within the master cylinder bore, most current inspection methods rely on endoscopy. This involves manually inserting the endoscope's flexible probe into the master cylinder bore, rotating the probe to capture images of the piston cups, and simultaneously visually inspecting the image on a screen. Clearly, traditional inspection methods, entirely manual, are inefficient and ill-suited for modern intelligent manufacturing. Utility Model Content

[0018] As mentioned in the background section, in order to solve the problems existing in the prior art, this embodiment provides an HCU master cylinder inner cup detection device, including: Frame 4, which has a testing station; Lifting mechanism 1 is located on one side of the inspection station and has a lifting end that can lift vertically. Image acquisition mechanism 2 is located on the lifting end. Image acquisition mechanism 2 has an acquisition probe 21 extending in the vertical direction and can acquire images through the acquisition probe 21. The acquisition probe 21 is set in the corresponding detection station. The drive mechanism 3 is located on the image acquisition mechanism 2 and is used to drive the acquisition probe 21 to rotate around its own central axis.

[0019] like Figure 1 and Figure 2 As shown, the frame 4 is approximately rectangular in shape and has a first space containing a testing station. The testing station is used to mount the main cylinder 5 to be tested. The main cylinder 5 is fixed to the testing station with its cylinder bore facing upwards. The lifting mechanism 1 is fixed to one side of the testing station. The image acquisition mechanism 2 is mounted on the lifting end, above the main cylinder 5. The acquisition probe 21 is a rigid tube probe from an industrial endoscope, vertically aligned with the cylinder bore. The drive mechanism 3 is mounted on the image acquisition mechanism 2 and connected to the acquisition probe 21, driving the probe 21 to rotate around its central axis to achieve complete image acquisition of the inner cup of the main cylinder 5. The image acquisition mechanism 2 is connected to a host computer, which can send the acquired cup image to the host computer. The host computer uses image processing technology to compare the acquired image with a standard image to check if the installation of the inner cup of the main cylinder 5 conforms to the standard. Image processing technology is relatively mature in industrial inspection and automation; the specific process will not be elaborated here.

[0020] In use, firstly, the lifting mechanism 1 is activated to raise the acquisition probe 21 vertically by a fixed distance, so that the space between the acquisition probe 21 and the inspection station can accommodate the main cylinder 5. The main cylinder 5 to be inspected is placed on the inspection station, at which point the main cylinder 5 is located below the acquisition probe 21, with the cylinder hole corresponding to the acquisition probe 21 vertically. Then, the lifting mechanism 1 is activated again to lower the acquisition probe 21 vertically by a fixed distance, allowing the acquisition probe 21 to extend into the main cylinder 5 from the port of the cylinder hole. At this point, the image of the inner cup of the inner cup of the cylinder hole can be acquired through the acquisition probe 21. The drive mechanism 3 is then activated to drive the acquisition probe 21 to rotate while simultaneously acquiring the image of the inner cup of the main cylinder 5, thus achieving complete acquisition of the image of the inner cup of the main cylinder 5. The acquired image of the inner cup is then sent to the host computer to check whether the installation of the inner cup meets the standard. Through the above-mentioned inspection device, the automatic acquisition of the image of the inner cup of the main cylinder 5 can be realized, which can better match modern production lines and has higher inspection efficiency compared with traditional inspection methods.

[0021] In a preferred embodiment, the frame 4 is provided with a rotating platform 41 and a second drive motor. The rotating platform 41 has a detection station and an installation station. The second drive motor is used to drive the rotating platform 41 to rotate around its own central axis.

[0022] like Figure 1 and Figure 2 As shown, the rotating platform 41 is set in the first space and rotatably connected to the frame 4. The second drive motor is also set on the frame 4 and is used to drive the rotating platform 41 to rotate around its own central axis. The inspection station and the installation station are symmetrically distributed about the central axis of the rotating platform 41. The installation station is used to set the main cylinder 5 of the leather cup to be installed. In use, the main cylinder 5 of the leather cup to be installed is fixed in the installation station, and the leather cup is installed into the groove in the cylinder hole using the installation tool. After the installation is completed, the second drive motor is started to drive the rotating platform 41 to rotate 180 degrees around its own central axis, and the main cylinder 5 after the leather cup is installed is rotated to the inspection station to check whether the installation of the leather cup meets the standard. At the same time, the main cylinder 5 that has been inspected is rotated to the installation station, the inspected main cylinder 5 is removed, and the main cylinder 5 of the next leather cup to be installed is fixed to the installation station to start the next cycle, thereby realizing a fast process from installation to inspection of the leather cup in the main cylinder 5, which greatly improves production efficiency.

[0023] In a preferred embodiment, both the inspection station and the installation station are provided with a limiting block 42 and a quick clamp 43, which can cooperate with each other to fix the main cylinder 5.

[0024] like Figure 2 and Figure 3 As shown, the cross-section of the main cylinder 5 is approximately rectangular. Three limiting blocks 42 are respectively set on the inspection station and the installation station, and the limiting blocks 42 on the two stations are respectively set accordingly. When the main cylinder 5 is set on the installation station, the three sides of the main cylinder 5 are respectively attached to the three limiting blocks 42. Then, by pressing down the handle of the quick clamp 43, the clamping end of the quick clamp 43 is pressed against the side of the main cylinder 5 where the limiting block 42 is not set, thereby fixing the main cylinder 5 relative to the installation station.

[0025] In a preferred embodiment, the lifting mechanism 1 includes: Base 11 is fixed on frame 4 and located on one side of the inspection station; A lifting cylinder 12 is mounted on a base 11, and an image acquisition mechanism 2 is mounted on the piston rod of the lifting cylinder 12.

[0026] like Figure 4As shown, the base 11 is fixed in the first space, located on one side of the rotating platform 41. The lifting cylinder 12 is fixed on the base 11. The piston rod of the lifting cylinder 12 extends vertically, and an image detection mechanism is provided on the free end of the piston rod. The lifting cylinder 12 drives the image acquisition mechanism 2, which can drive the acquisition probe 21 to move vertically. After the diaphragm of the main cylinder 5 installed at the installation station is installed, the lifting cylinder 12 is started to drive the acquisition probe 21 to move upward a fixed distance, so that the distance between the acquisition probe 21 and the rotating platform 41 is sufficient for the main cylinder 5 to pass through. The second drive motor is started, and the second drive motor drives the rotating platform 41 to rotate 180 degrees around its own central axis, rotating the main cylinder 5 after the diaphragm is installed to the detection station. At this time, the acquisition probe 21 is aligned vertically with the cylinder hole of the main cylinder 5. The lifting cylinder 12 is started again to drive the acquisition probe 21 to move downward a fixed distance, so that the acquisition probe 21 extends into the main cylinder 5 from the port of the cylinder hole, thereby detecting whether the installation of the diaphragm in the main cylinder 5 meets the standard.

[0027] In a preferred embodiment, the image acquisition mechanism 2 includes: Fixed bracket 22 is provided on the lifting end; Camera 24 is mounted on a fixed bracket 22; Endoscope 23 is rotatably connected to fixed bracket 22. Camera 24 and acquisition probe 21 are coaxially mounted on the upper and lower sides of endoscope 23, respectively. Camera 24 and acquisition probe 21 are connected through the optical path of endoscope 23.

[0028] like Figure 4 As shown, the fixed bracket 22 is approximately a U-shaped frame structure. The fixed bracket 22 is fixed on the piston rod of the lifting cylinder 12, and its U-shaped port faces the horizontal direction. The fixed bracket 22 includes a first part and a second part that are integrally connected in the vertical direction. A first channel is opened on the first part. The camera 24 is fixed to the first part by a fixing member and is placed in the first channel. The endoscope 23 is rotatably connected to the second part in the vertical direction. The camera 24 and the endoscope 23 are rotatably connected by an adapter. A sealing ring is provided between the bottom end of the camera 24 and the top end of the endoscope 23. The sealing ring is used to seal the connection between the camera 24 and the endoscope 23 to prevent dust from entering and to avoid wear caused by the rotation of the endoscope 23. The bottom end of the endoscope 23 is fixed to the acquisition probe 21, so the camera 24 can be connected to the acquisition probe 21 through the optical path of the endoscope 23.

[0029] In a preferred embodiment, the drive mechanism 3 includes: The first drive motor 31 is mounted on the fixed bracket 22, and the drive shaft of the first drive motor 31 passes through the fixed bracket 22 in a vertical direction. Drive wheel 32, drive wheel 32 is sleeved and fixed on drive shaft; Driven wheel 33 is mounted and fixed on endoscope 23. Driven wheel 33 and drive wheel 32 are tensioned together by a transmission belt 34.

[0030] like Figure 4 As shown, the first drive motor 31 is fixed at the end of the second part away from the endoscope 23. The drive shaft of the first drive motor 31 passes through the second part vertically and extends between the second part and the first part. The drive wheel 32 is sleeved and fixed on the drive shaft, and the driven wheel 33 is sleeved and fixed on the endoscope 23 and corresponds to the drive wheel 32 in the horizontal direction. When the first drive motor 31 is started, the drive wheel 32 drives the driven wheel 33 to rotate through the transmission belt 34, thereby causing the acquisition probe 21 to rotate around its own central axis.

[0031] In a preferred embodiment, a light source 25 is fixed to one side of the endoscope 23.

[0032] like Figure 3 As shown, the light source 25 is fixed to one side of the endoscope 23 and extends horizontally. By setting the light source 25, the light generated by the light source 25 can enter the cylinder bore through the acquisition probe 21 via the endoscope 23 to supplement the light inside the cylinder bore, so as to ensure that the camera 24 can acquire a clear image with sufficient light.

[0033] In a preferred embodiment, a first bearing 26 is provided between the endoscope 23 and the fixation bracket 22.

[0034] like Figure 4 As shown, the first bearing 26 can be a deep groove ball bearing in the prior art. The first bearing 26 is located on the second part, and the outer ring is fixed to the second part. The endoscope 23 is fixed to the inner ring of the first bearing 26. By setting the first bearing 26, the endoscope 23 can rotate smoothly relative to the fixed bracket 22.

[0035] Working Principle: During use, the main cylinder 5, where the leather cup to be installed, is fixed at the installation station. Using installation tools, the leather cup is installed into the groove within the cylinder bore. After installation, the lifting cylinder 12 is activated to drive the acquisition probe 21 upwards a fixed distance, ensuring the distance between the acquisition probe 21 and the rotating platform 41 is sufficient for the main cylinder 5 to pass through. Then, the second drive motor is activated to drive the rotating platform 41 to rotate 180 degrees around its central axis, rotating the main cylinder 5 with the installed leather cup to the detection station. At this point, the acquisition probe 21 aligns vertically with the cylinder bore of the main cylinder 5. The lifting cylinder 12 is activated again to drive the acquisition probe 21 downwards a fixed distance, allowing the acquisition probe 21 to extend into the main cylinder 5 from the port of the cylinder bore. The camera 24 then captures images of the leather cup installation within the main cylinder 5. The system collects data and simultaneously activates the first drive motor 31, which drives the drive wheel 32 to rotate. The drive wheel 32, through the transmission belt 34, drives the driven wheel 33 to rotate, causing the acquisition probe 21 to rotate around its own central axis. This allows for the complete acquisition of the image of the inner cup of the main cylinder 5. The acquired image of the inner cup is then sent to the host computer to check whether the installation of the inner cup meets the standards. After the check is completed, the lifting cylinder 12 is activated to drive the acquisition probe 21 to move upward a fixed distance, causing the acquisition probe 21 to disengage from the cylinder bore of the main cylinder 5. The second drive motor is then activated to drive the rotating platform 41 to rotate 180 degrees around its own central axis, rotating the main cylinder 5, which has been checked, to the installation position. The main cylinder 5 is then removed from the installation position, and the next cycle begins.
