Description

Technical Field

[0001] The present application relates to the technical field of air tightness and stroke detection equipment, and in particular, to an air tightness and stroke detection device for a bypass valve actuator. Background Art

[0002] After searching, the Chinese patent number is CN202120952055.8, which discloses a high-strength and stable bypass valve actuator. The bypass valve actuator includes: a housing, a diaphragm, a linkage rod assembly, a spring and a spring seat. The housing is provided with an intake pipe and a linkage rod through hole. The diaphragm is arranged inside the housing and divides the inner cavity of the housing into a pressure chamber and a driven chamber. The intake pipe is connected to the pressure chamber, and the linkage rod is connected to the driven chamber through the hole. One end of the linkage rod assembly is arranged in the driven chamber and contacts the diaphragm, and the other end passes through the linkage rod through hole. The spring is sleeved on the linkage rod assembly, and one end thereof abuts on the spring seat, and the other end abuts on the linkage rod assembly. The bypass valve actuator also includes a pressure plate assembly, which includes a plate body and an actuator fixing part. The plate body is provided with a fixed connection hole, which cooperates with and is fixedly connected to the actuator fixing part. The housing is also provided with a fixing part through hole, and the actuator fixing part passes through the fixing part through hole and is fixed to the turbocharger.

[0003] After the bypass valve actuator is assembled, it needs to be tested for air tightness and stroke to ensure whether the bypass valve actuator is qualified. At present, the air tightness and stroke of multiple bypass valve actuators are often tested at one time. When an unqualified bypass valve actuator appears, a marking pen is often used to automatically mark the bypass valve actuator to distinguish it from a qualified bypass valve actuator. However, the dot mark is small, and unqualified bypass valve actuators are often flowed into the qualified area. In addition, manual inspection is often used to check whether the identification QR code on the bypass valve actuator is affixed or whether it is affixed correctly, which wastes manpower and brings a bad user experience.

[0028] Example

[0029] See also Figure 1 - Figure 6 The present application provides a technical solution: an air tightness and stroke detection device for a bypass valve actuator, comprising a base plate 110, a frame 120, a mounting seat 130, a barcode scanner 180, an inflation mechanism 170, a marking mechanism 190, and a stroke detection mechanism 191. The frame 120, the mounting seat 130, and the barcode scanner 180 are all fixed on the upper surface of the base plate 110. The device also includes a first locking member 140.

A plurality of barcode scanners 180 are provided, and the plurality of barcode scanners 180 are fixed to the mounting seat 130 at linear equidistant intervals.

[0030] The inflation mechanism 170 is mounted on the base plate 110. The setting of the inflation mechanism 170 enables the bypass valve actuator to be inflated. The inflation mechanism 170 includes a base 171, a first cylinder 172, an inflation head 173 and an air pipe 174. The base 171 is fixed to the upper surface of the base plate 110, the first cylinder 172 is fixed to the base 171, the piston rod end of the first cylinder 172 is fixed to the outer wall of the inflation head 173, and one end of the air pipe 174 is set on the inflation head 173. The mounting base 130 is provided with a first positioning groove 150 and a second positioning groove 160. The second positioning groove 160 and the inflation head 173 are correspondingly arranged.

[0031] The marking mechanism 190 is mounted on the base plate 110. The marking mechanism 190 is used to mark the bypass valve actuator that is unqualified or unqualified in labeling. The marking mechanism 190 includes a support block 1901, a second cylinder 1902, a motor 1903, a circular plate 1904, a hollow cylinder 1905 and a second locking member 1906. The support block 1901 is fixed on the upper surface of the base plate 110, the cylinder of the second cylinder 1902 is fixed on the outer wall of the support block 1901, and the movable part of the second cylinder 1902 is fixed on the outer wall of the support block 1901. The end of the plug rod is fixed to the outer wall of the motor 1903, the output shaft of the motor 1903 is fixed to the circular plate 1904, one end of the hollow cylinder 1905 is fixed to the circular plate 1904, and the second locking member 1906 is threaded through the hollow cylinder 1905. The arrangement of the second cylinder 1902, the motor 1903, the circular plate 1904, the hollow cylinder 1905, and the second locking member 1906 facilitates drawing a circle mark on the bypass valve actuator. In this embodiment, the first locking member 140 and the second locking member 1906 are bolts.

[0032] The stroke detection mechanism 191 is installed on the frame 120. The stroke detection mechanism 191 is used to detect the air tightness and stroke of the bypass valve actuator. The stroke detection mechanism 191 includes a third cylinder 1911, a guide block 1912, a spring 1913, a corrugated hose 1914 and a displacement sensor 1915. The third cylinder 1911 is fixed on the frame 120. The piston rod end of the third cylinder 1911 is fixed on the upper surface of the guide block 1912. One end of the spring 1913 and one end of the corrugated hose 1914 are both fixed on the guide block 1912. The spring 1913 is arranged in the corrugated hose 1914. The other end of the spring 1913 and the other end of the corrugated hose 1914 are both fixed on the upper surface of the displacement sensor 1915. A through hole is opened on the guide block 1912. The displacement sensor 1915 is slidably inserted in the through hole. The setting of the through hole facilitates the linkage rod body to pass through the guide block 1912.

[0033] Specifically, the working principle of the air tightness and stroke detection device for the bypass valve actuator is as follows: when in use, insert the marking pen into the hollow cylinder 1905, rotate the second locking piece 1906, and the end of the second locking piece 1906 squeezes the outer wall of the marking pen to fix the marking pen in the hollow cylinder 1905, insert the assembled bypass valve actuator shell into the first positioning groove 150, and at the same time make the air intake pipe on the shell clamped into the second positioning groove 160, and make the end of the linkage rod body of the bypass valve actuator face upward, and the barcode scanner 180 works to scan the identification QR code on the bypass valve actuator. When it cannot be scanned, it means that the identification QR code on the bypass valve actuator is not affixed or not affixed correctly. The buzzer on the frame 120 works to alarm, and at the same time, the second cylinder 1902 and the motor 1903 work. The second cylinder 1902 drives the marking pen to move longitudinally, and the motor 1903 works to drive the marking pen to rotate. Under the joint action of the second cylinder 1902 and the motor 1903, a circular mark is drawn on the bypass valve actuator. When the barcode scanner 180 can recognize the identification QR code on the bypass valve actuator, the first cylinder 172 and the third cylinder 1911 work, and the piston rod of the third cylinder 1911 drops a specified distance, so that the displacement sensor 1915 is fitted together with the linkage rod body, and the piston rod of the first cylinder 172 drives the inflation head 173 to be sleeved on the intake pipe. The inflation head 173 works first to The bypass valve actuator is filled with specified gas. Under the action of the diaphragm of the bypass valve actuator, the linkage rod body drives the displacement sensor 1915 to move upward. When the upward movement distance of the displacement sensor 1915 does not reach the set value, it indicates that the air tightness of the bypass valve actuator is unqualified, the buzzer alarms, and the marking mechanism 190 works to draw a circle mark on the bypass valve actuator. When the upward movement distance of the displacement sensor 1915 reaches the set value, the inflation head 173 continues to inflate the bypass valve actuator, and under the action of the linkage rod body, the spring 1913 and the corrugated hose 1914 are driven to move upward. When it moves to the maximum height, the inflation head 173 is deflated, and the linkage rod body is lowered under the reaction of the spring 1913. During the inflation and deflation of the head 173, the stroke of the bypass valve actuator is detected. When the displacement sensor 1915 detects that the stroke is unqualified, the unqualified bypass valve actuator is marked with a circle using the marking mechanism 190 according to the above steps. When the displacement sensor 1915 detects that the stroke is qualified, it means that the bypass valve actuator is qualified. The air tightness and stroke detection device for the bypass valve actuator uses the barcode scanner 180 to detect the QR code on the bypass valve actuator, saving manpower, and uses the marking mechanism 190 to mark the bypass valve actuator with a circle. The mark is large, which effectively prevents unqualified bypass valve actuators from flowing into the qualified area, giving users a better user experience.

[0034] It should be noted that the specific models and specifications of the first cylinder 172, the inflation head 173, the barcode scanner 180, the second cylinder 1902, the motor 1903, the third cylinder 1911 and the displacement sensor 1915 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.
