Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to an automobile tensioner inspection device. Background Art

[0002] The automobile tensioner is a commonly used retaining device on the belt and chain transmission system. Its characteristic is to keep the belt and chain with appropriate tension during the transmission process, so as to avoid the belt slipping, or to prevent the synchronous belt from jumping teeth or being dragged out, or to prevent the chain from loosening or falling off, and to reduce the wear of the sprocket and chain. The structure of the automobile tensioner is varied, which generally includes a fixed structure and an elastic automatic adjustment structure. Among them, the fixed structure mostly uses a fixed adjustable sprocket to adjust the tension of the belt and sprocket, and the elastic automatic adjustment structure mostly uses elastic components that can automatically rebound to control the tension of the belt and chain. Domestic automatically adjustable chain automobile tensioners mostly use spring structures, while foreign automobile tensioners mostly use rubber components.

[0003] The tightness of the tensioner needs to be tested during the production process. The existing testing method requires manual separation based on the test results, which not only increases the workload but also poses a safety hazard. Summary of the invention

[0004] The purpose of the present invention is to provide an automobile tensioner inspection device to solve the technical problem that manual separation is required after inspection, which not only increases the workload but also poses a safety hazard.

[0005] To achieve the above purpose, the specific technical solution of an automobile tensioner inspection device of the present invention is as follows:

[0006] A vehicle tensioner inspection device, characterized in that it includes a rotating part, a collecting component, a sorting component, an unqualified discharge port, a qualified discharge port, a reset component, a bearing part, a detection component and a driving component, wherein the rotating part is rotatably arranged on the collecting component, and at least one bearing part for placing the tensioner is provided on the rotating part, and the two are connected when the bearing part rotates to the above-mentioned collecting component, and an unqualified discharge port and a qualified discharge port are provided at the end of the collecting component away from the rotating part, and a sorting component for controlling the switch of the unqualified discharge port or the qualified discharge port is provided inside the collecting component, and when the bearing part rotates to the position of the detection component, the tensioner located inside the bearing part is connected to the detection component, one end of the reset component is connected to the sorting component and the other end is connected to the collecting component, and a driving component for driving the sorting component to rotate is provided on the detection component.

[0007] Furthermore, the rotating part is a rotating ring.

[0008] Furthermore, the bearing part is a storage slot. When the number of the bearing parts is greater than one, the angle formed by adjacent bearing parts and the center of the circle is greater than the angle formed by the collecting component and the detecting component and the center of the circle. A through hole connected to the storage slot is provided on the rotating part.

[0009] Furthermore, the collecting assembly includes a collecting cylinder, a top plate and an inlet hole. The collecting cylinder is provided with a top plate, and the top plate is provided with an inlet hole connected to the collecting cylinder. The rotating part rotates on the top plate, and the unqualified discharge port and the qualified discharge port are arranged at one end of the collecting cylinder away from the top plate.

[0010] Furthermore, the sorting component is a rotating plate, and the sorting component is arranged inside the collecting barrel to control the qualified discharge outlet or the switch of the qualified discharge outlet.

[0011] Furthermore, the reset component is an arc spring, one end of which is connected to the collecting cylinder and the other end of which is connected to the sorting component.

[0012] Further, the detection assembly includes an air intake pipe, a sealing cover is provided on the air intake pipe, the air intake pipe and the sealing cover are connected, the sealing cover and the bearing part are fitted, when the sealing cover and the through hole are connected, the air intake pipe and the corresponding tensioner are connected, and the outer wall thickness of the sealing cover is greater than the aperture of the through hole.

[0013] Furthermore, the driving assembly includes a connecting pipe, a connecting bolt, a spring, a rack and a gear.

[0014] Furthermore, the collection assembly is provided with a storage box for replenishing the tensioner inside the bearing portion.

[0015] The advantages of the present invention are:

[0016] The present invention drives the tensioner inside the bearing part to rotate through the rotating part. When the bearing part rotates and the detection component is in relative position, the detection component and the tensioner are connected, and gas with a fixed air pressure is injected into the tensioner. After the gas enters the tensioner, the air pressure inside the detection component is observed after a period of time. When the product is qualified, the pressure remains unchanged. The current pressure inside the detection component acts on the driving component, and the driving component drives the sorting component to close the unqualified discharge port and open the qualified discharge port. The rotating part drives the detected tensioner to enter the collecting component and then be discharged from the qualified discharge port. If the tensioner is unqualified, the internal pressure of the detection component decreases after a period of time, and the reset component pushes the sorting component to open the unqualified discharge port and close the qualified discharge port. Then the tensioner is discharged through the unqualified discharge port, thereby completing automatic detection and sorting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0026] like Figure 1-5As shown, an automobile tensioner inspection device is characterized in that it includes a rotating part 1, a collecting component 2, a sorting component 3, an unqualified discharge port 4, a qualified discharge port 5, a reset component 6, a bearing part 7, a detection component 9 and a driving component 11, the rotating part 1 is rotatably arranged on the collecting component 2, at least one bearing part 7 for placing the tensioner is provided on the rotating part 1, and the two are connected when the bearing part 7 rotates to the collecting component 2. The collecting component 2 is provided with an unqualified discharge port 4 and a qualified discharge port 5 at the end away from the rotating part 1, and the collecting component 2 is provided with a sorting component 3 for controlling the switch of the unqualified discharge port 4 or the qualified discharge port 5. When the bearing part 7 rotates to the detection component 9 position, the tensioner located inside the bearing part 7 is connected to the detection component 9, one end of the reset component 6 is connected to the sorting component 3 and the other end is connected to the collecting component 2, and the detection component 9 is provided with a driving component for driving the sorting component 3 to rotate. Component 11 drives the tensioner inside the bearing part 7 to rotate through the rotating part 1. When the bearing part 7 rotates and is in a relative position with the detection component 9, the detection component 9 is connected to the tensioner, and gas with a fixed air pressure is injected into the tensioner. After the gas enters the tensioner, the air pressure inside the detection component 9 is observed after a period of time. When the product is qualified, the pressure remains unchanged. The current pressure inside the detection component 9 acts on the driving component 11. The driving component 11 drives the sorting component 3 to close the unqualified discharge port 4 and open the qualified discharge port 5. The rotating part 1 drives the detected tensioner to enter the collecting component 2 and then be discharged from the qualified discharge port 5. If the tensioner is unqualified, the internal pressure of the detection component 9 decreases after a period of time, and the reset component 6 pushes the sorting component 3 to open the unqualified discharge port 4, and closes the qualified discharge port 5. Then the tensioner is discharged through the unqualified discharge port 4, thereby completing automatic detection and sorting.

[0027] Among them, Figure 1-5 As shown, the rotating part 1 is a rotating ring.

[0028] Among them, Figure 1-5 As shown, the bearing portion 7 is a storage groove. When the number of bearing portions 7 is greater than one, the angle formed by adjacent bearing portions 7 and the center of the circle is greater than the angle formed by the collecting component 2 and the detecting component 9 and the center of the circle. A through hole 8 connected to the storage groove is provided on the rotating portion 1, so as to avoid the structure of the subsequent tensioner detection affecting the discharge result of the tensioner after the previous detection.

[0029] Among them, Figure 1-5As shown, the collecting assembly 2 includes a collecting barrel 2-1, a top plate 2-2 and an entry hole 2-3. The collecting barrel 2-1 is provided with a top plate 2-2, and the top plate 2-2 is provided with an entry hole 2-3 connected to the collecting barrel 2-1. The rotating part 1 rotates on the top plate 2-2, and the unqualified discharge port 4 and the qualified discharge port 5 are arranged on the end of the collecting barrel 2-1 away from the top plate 2-2, and rotate to the bearing part 7 above the entry hole 2-3. The tensioner after detection inside the bearing part 7 will enter the collecting barrel 2-1 through the entry hole 2-3 for sorting.

[0030] Among them, Figure 1-5 As shown, the sorting component 3 is a rotating plate, and the sorting component 3 is arranged inside the collecting barrel 2-1 to control the switch of the qualified discharge port 4 or the qualified discharge port 5. The sorting component 3 is rotatably arranged inside the collecting barrel 2-1 through the mounting shaft.

[0031] Among them, Figure 1-5 As shown, the reset component 6 is an arc spring, one end of which is connected to the collecting cylinder 2-1 and the other end is connected to the sorting component 3. One end of the reset component 6 is arranged on the collecting cylinder 2-1 through a connecting plate, and the other end is arranged on the above-mentioned rotating shaft through a connecting plate.

[0032] Among them, Figure 1-5 As shown, the detection component 9 includes an air intake pipe 9-1, on which a sealing cover 9-2 is provided. The air intake pipe 9-1 is connected to the sealing cover 9-2, and the sealing cover 9-2 is fitted with the bearing portion 7. When the sealing cover 9-2 is connected to the through hole 8, the air intake pipe 9-1 is connected to the corresponding tensioner. The thickness of the outer wall of the sealing cover 9-2 is greater than the aperture of the through hole 8, so that when the through hole 8 is separated from the sealing cover 9-2, the air pressure inside the air intake pipe 9-1 is prevented from being thrown out through the sealing cover 9-2 and affecting the sorting and discharging structure. It is detected that there is a certain amount of gas inside the air intake pipe 9-1, so that the initial detection pressure of the air intake pipe 9-1 reaches a preset value to detect the tensioner. During one end of the detection time, the rotating part 1 does not rotate, and the rotating part 1 is provided with a matching servo motor.

[0033] Among them, Figure 1-5 As shown, the driving assembly 11 includes a connecting tube 11-1, a connecting bolt 11-2, a spring 11-3, a rack 11-4 and a gear 11-5. The connecting tube 11-1 is arranged on the air intake pipe 9-1, the connecting bolt 11-2 slides inside the connecting tube 11-1, the connecting tube 11-1 and the connecting bolt 11-2 are provided with a spring 11-3, the rack 11-4 is arranged on the connecting bolt 11-2, and the rack 11-4 is connected to the sorting assembly 3 through the gear 11-5. The pressure of the air intake pipe 9-1 will push the connecting bolt 11-2 to move, and the connecting bolt 11-2 drives the rack 11-4 to move. The moving rack 11-4 drives the gear 11-5 arranged on the sorting assembly 3 through the above-mentioned rotating shaft to rotate, and then drives the sorting assembly 3 to rotate.

[0034] Among them, Figure 1-5 As shown, the collecting assembly 2 is provided with a storage box 10 for replenishing the tensioner inside the carrying portion 7, and automatically replenishing the tensioner to be detected into the empty carrying portion 7 to form automatic detection and sorting.
