Description

Technical Field

[0001] The invention relates to the field of strength detection, and in particular to a quick exhaust valve and a detection device. Background Art

[0002] The gas quick exhaust valve switches the air intake and exhaust through the internal sliding column. The quick exhaust valve can be used on the bellows pump to increase the exhaust speed in the pump body, thereby increasing the running speed of the pump. There is an air inlet on the quick exhaust valve, and an air outlet on the side connected to the pump body. The exhaust hole on the quick exhaust valve is connected to the muffler. When working, the gas enters from the air inlet, and the gas pushes the edge of the leather cup open to enter the quick exhaust valve. Due to the particularity of the leather cup, the gas can only enter in one direction and cannot flow back, which is equivalent to a one-way valve. Then it enters the air cavity of the pump through the hole on the side, and the excess gas is discharged from the exhaust hole. In addition, because the exhaust hole is installed with a muffler, the effect of reducing noise is achieved.

[0003] During the processing of quick exhaust valves, in order to ensure product quality, the valve body is usually impacted by spring impact to test the strength of the valve body. However, in actual testing, after one impact is completed, workers need to manually control the spring to store energy before releasing it for the next impact. The operation process is quite cumbersome, resulting in inconvenience in testing. Summary of the invention

[0016] 3. When the No. 1 shaft rotates in the reverse direction to drive the quick exhaust valve to reset after the side shift, you can first loosen the bolts to allow the No. 1 guide seat to move downward to fit on the swivel and the No. 2 guide seat, and then rotate the bolts in the reverse direction to allow the bolts to enter the fixing holes below to fix the downward-moving No. 1 guide seat. During the reverse rotation of the No. 1 shaft, the guide wheel can pass through the slope of the No. 1 guide seat and move through the No. 2 guide seat to avoid the vertical edge of the No. 2 guide seat being blocked by the guide wheel and affecting the rotation during the reverse rotation, thereby ensuring the normal reset operation.

DETAILED DESCRIPTION

[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0027] like Figure 1-Figure 8The quick exhaust valve and detection device shown in the figure include a machine base 1, a fixing frame 22 is fixedly installed at the upper side edge of the machine base 1, and an axis frame 21 is embedded through the end of the fixing frame 22, and the fixing frame 22 plays a role in fixing the axis frame 21, and one end of the axis frame 21 is rotatably installed through the first axis body 12, and the axis frame 21 plays a role in supporting the first axis body 12, the third axis body 19, and the second axis body 16. A guide rod 26 is elastically installed at the front end of the axis frame 21, and an impact head 7 is fixedly installed at the lower end of the guide rod 26. The guide rod 26 plays a role in guiding the impact head 7, and a guide wheel 36 is installed at the upper end of the guide rod 26. The impact head 7 plays a role in impact testing the quick exhaust valve 8. A swivel 13 is coaxially fixedly installed on the outer surface of the first axis body 12, and the guide wheel 36 is attached to the upper end of the swivel 13. A No. 2 guide seat 35 is extended, and the No. 1 shaft body 12 drives the No. 2 guide seat 35 on the swivel 13 to rotate in a circle, so that the guide wheel 36 can move up along the slope of the No. 2 guide seat 35, and then drive the guide rod 26 to move up, so that the impact spring 28 can shrink and be in an energy storage state. When the No. 2 guide seat 35 continues to rotate in a circle, the guide wheel 36 moves to the vertical edge of the No. 2 guide seat 35, the impact spring 28 is released to produce an impact, thereby cyclically driving the impact head 7 to continuously perform an impact test on the quick-exhaust valve 8. A guide is installed at the end of the No. 1 shaft body 12, and a push valve member is installed on the fixed frame 22. The push valve member is provided with a quick-exhaust valve 8, and the lower end of the impact head 7 is attached to the quick-exhaust valve 8. The quick-exhaust valve 8 switches the intake and exhaust through an internal sliding column. The quick-exhaust valve 8 can be used on a wind bag pump to increase the exhaust speed in the pump body, thereby increasing the running speed of the pump. There is an air inlet 39 on the quick exhaust valve 8, and an air outlet 38 on the side connected to the pump body. At the same time, the exhaust hole on the quick exhaust valve 8 is connected to the muffler 40. During operation, gas enters from the air inlet 39, and the gas pushes the edge of the leather cup to enter the quick exhaust valve 8. Due to the particularity of the leather cup, the gas can only enter in one direction and cannot flow back, which is equivalent to a one-way valve. Then, the gas enters the air cavity of the pump through the air outlet 38 on the side, and the excess gas is discharged from the exhaust hole. Because the muffler 40 is installed at the exhaust hole, the effect of reducing noise is achieved. Since the quick exhaust valve 8 is a prior art and has been widely used, it is not elaborated in detail here.

The No. 1 guide seat 31 and the No. 2 guide seat 35 are arranged oppositely, so that when the No. 1 shaft body 12 rotates in the reverse direction, the guide wheel 36 can pass through the slope of the No. 1 guide seat 31 and move through the No. 2 guide seat 35, so as to avoid the phenomenon that the vertical edge of the No. 2 guide seat 35 is blocked by the guide wheel 36 and the rotation is affected during the reverse rotation. The outer surface of the fixing sleeve 32 is penetrated and tightened with bolts 33, and two fixing holes 34 are symmetrically provided on the upper outer surface of the No. 1 shaft body 12. The ends of the bolts 33 fit in the upper fixing holes 34, and the cooperation of the bolts 33 and the fixing holes 34 serves to fix the fixing sleeve 32.

[0031] The push valve member includes a guide seat 20 fixedly mounted on a fixing frame 22, a push valve tooth plate 5 is slidably mounted inside the guide seat 20, the guide seat 20 serves to guide the push valve tooth plate 5, the upper portion of the push valve tooth plate 5 is meshed with a push valve gear 24, the push valve gear 24 can push the push valve tooth plate 5, so that the push valve tooth plate 5 can slide in the guide seat 20, so as to drive the quick exhaust valve 8 to slowly move sideways, so that the impact head 7 can impact multiple positions on the quick exhaust valve 8 during the detection process, and the push valve tooth plate 5 can be pushed. A fourth shaft 25 is embedded through the interior of the valve gear 24, and the fourth shaft 25 is rotatably connected to the lower end of the shaft frame 21.

A connecting frame 6 is fixedly installed between the rear ends of the two limit angles 9 at the rear. The end of the connecting frame 6 is fixed to the valve push gear plate 5. The limit angles 9 support and limit the quick exhaust valve 8.

[0032] A carrier 37 is fixedly installed between the lower ends of the four limit angles 9, and a top wheel 10 is installed at the lower end of the carrier 37. The carrier 37 serves to fix the four limit angles 9 together. The top wheel 10 is attached to the upper end of the machine base 1, and the top wheel 10 can roll on the machine base 1 to support the limit angle 9 to ensure the supporting force of the limit angle 9. The other end of the shaft frame 21 is rotatably installed with the third shaft body 19. The lower end of the third shaft body 19 and the end of the fourth shaft body 25 are coaxially inlaid with a bevel gear 23.

The small gear 14 meshes with the large gear 17, and the small gear 14 and the large gear 17 play a role of speed reduction transmission.

[0035] During the inspection, the quick exhaust valve 8 is placed on the limit angle 9 to support and limit the quick exhaust valve 8 through the limit angle 9, and then the servo motor 11 works to drive the drive shaft 3 to rotate, so that the drive shaft 3 drives the No. 1 shaft 12 to rotate through the belt 4, so that the No. 2 guide seat 35 on the swivel 13 is driven by the rotating No. 1 shaft 12 to rotate in a circle, so that the guide wheel 36 can move up along the slope of the No. 2 guide seat 35, and then drive the guide rod 26 to move up, so that the impact spring 28 can shrink and be in an energy storage state. When the No. 2 guide seat 35 continues to rotate in a circle and the guide wheel 36 moves to the vertical edge of the No. 2 guide seat 35, the impact spring 28 is released to produce an impact, so as to drive the impact head 7 to continuously perform an impact test on the quick exhaust valve 8 in this cycle to detect the strength of the quick exhaust valve 8. During this process, the No. 1 shaft 12 will also pass through the No. 1 small gear 14, the No. 1 large gear 17 and the No. 2 small gear The transmission of the wheel 15 and the No. 2 large gear 18 drives the No. 3 shaft 19 to rotate slowly, and then drives the push valve gear 24 on the No. 4 shaft 25 to rotate slowly through the bevel gear 23, so as to push the push valve tooth plate 5, so that the push valve tooth plate 5 can slide in the guide seat 20, so as to drive the quick exhaust valve 8 to move slowly sideways, so that the impact head 7 can impact multiple positions on the quick exhaust valve 8 during the detection process, so as to improve the detection accuracy. When the push valve tooth plate 5 needs to be reset after the stroke ends, the bolt 33 can be loosened first, so that the No. 1 guide seat 31 can move down to fit on the swivel 13 and the No. 2 guide seat 35, and then the bolt 33 is rotated in the opposite direction, so that the bolt 33 enters the fixing hole 34 below to fix the No. 1 guide seat 31 that has moved down, and then the No. 1 shaft 12 is controlled to rotate in the opposite direction, so as to drive the push valve gear 24 to reverse, so as to drive the push valve tooth plate 5 to move in the opposite direction and reset.
