Description

Technical Field

[0001] This utility model relates to the technical field of detecting the thickness of sealing rings, and in particular to a detection device for detecting the thickness of sealing rings. Background Technology

[0002] A workshop used an injection molding machine to produce a batch of products such as Figures 1-2 The sealing ring 1 shown is made of rubber. This sealing ring 1 is used to install inside a valve to seal the valve.

[0003] Due to manufacturing process limitations, some of the sealing rings 1 produced in a batch have a thickness exceeding the design thickness. Therefore, it is necessary to inspect the thickness of each sealing ring 1 produced. The reason for this inspection is that if the thickness of a sealing ring 1 exceeds the design thickness, it cannot be installed into the valve.

[0004] The specific method used by workers to inspect the thickness of seal ring 1 is as follows:

[0005] S1. The worker takes a sealing ring 1 to be tested from the material basket and places the sealing ring 1 flat on the table of the machine 2 so that the sealing ring 1 is in a horizontal state.

[0006] S2. The worker moves the sealing ring 1 horizontally to ensure that the right end of the sealing ring 1 is suspended outside the machine base 2.

[0007] S3. The worker holds a vernier caliper 3 and then uses the two contact heads of the vernier caliper 3 to contact the top and bottom surfaces of the right end of the sealing ring 1, and then reads the thickness value of the sealing ring 1.

[0008] If the thickness value is less than or equal to the design thickness, it means that the thickness of the tested sealing ring 1 meets the requirements, and the worker judges the sealing ring 1 as a qualified product.

[0009] If the thickness value is greater than the design thickness, it means that the thickness of the tested sealing ring 1 does not meet the requirements. The worker judges the sealing ring 1 as a defective product, thus completing the thickness test of the first sealing ring 1.

[0010] S4. Workers can repeat steps S1 to S3 multiple times to complete the thickness test of all sealing rings 1 in the workshop.

[0011] However, while the inspection methods used by workers in the workshop can detect the thickness of sealing ring 1, the following technical defects still emerge in actual operation:

[0012] Each time the thickness of a sealing ring 1 is tested, the worker needs to manually operate the vernier caliper 3 to complete the test. Moreover, the number of sealing rings 1 to be tested each day is as high as 160. This not only increases the workload of the workers, but also means that the thickness of the sealing rings 1 can only be tested one by one, which takes a long time to complete the test of all 160 sealing rings 1 in one day, thus reducing the efficiency of the sealing ring 1 thickness test.

[0013] Therefore, there is an urgent need for a testing device that can greatly reduce the workload of workers and greatly improve the efficiency of sealing ring thickness detection. Utility Model Content

[0014] The purpose of this invention is to overcome the shortcomings of the prior art and provide a detection device for detecting the thickness of sealing rings that greatly reduces the workload of workers and greatly improves the efficiency of detecting the thickness of sealing rings.

[0015] The purpose of this utility model is achieved through the following technical solution: a detection device for detecting the thickness of a sealing ring, comprising two vertical plates fixed on a pad, a horizontally arranged strip rod fixed between the two vertical plates, a movable seat slidably mounted on the strip rod that can move along its length direction, a vertically arranged lifting cylinder fixed on the top surface of the movable seat, a lifting plate fixed on the working end of the piston rod of the lifting cylinder, a plurality of connecting columns fixed on the top surface of the lifting plate at intervals along its length direction, a positioning plate connected to the top of each connecting column, a positioning countersunk hole opened on the top surface of the positioning plate, the diameter of the positioning countersunk hole being larger than the outer diameter of the sealing ring;

[0016] The pad is also fixed with a fixed seat located outside the right upright plate. The top of the fixed seat is connected to a horizontal plate extending to the left and directly above the lifting plate. Thin rods corresponding to the positioning disk slide through the horizontal plate along its length. The top of each thin rod is connected to a displacement sensor supported on the top surface of the horizontal plate.

[0017] The movable seat has through holes on both its left and right side walls, and both through holes of the movable seat are matched with the strip-shaped square rod.

[0018] Guide columns are fixed on the fixed surface of the movable seat and on the left and right sides of the lifting cylinder. Guide sleeves are fixed on the bottom surfaces of the left and right ends of the lifting plate. The two guide sleeves are respectively fitted onto the two guide columns, and the guide columns penetrate the lifting plate upwards.

[0019] A flange is fixed to the bottom of the connecting column, and the flange is fixed to the lifting plate with screws to detachably fix the connecting column to the lifting plate.

[0020] The lifting plate is equipped with four connecting columns.

[0021] The detection device also includes a controller, which is connected to the signal lines of the lifting cylinder and four displacement sensors.

[0043] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0044] like Figures 5-11 As shown, a detection device for detecting the thickness of a sealing ring includes two vertical plates 4 fixed to a pad, a horizontally arranged strip rod 5 fixed between the two vertical plates 4, a movable seat 6 slidably mounted on the strip rod 5 and movable along its length, a vertically arranged lifting cylinder 7 fixed on the top surface of the movable seat 6, a lifting plate 8 fixed on the working end of the piston rod of the lifting cylinder 7, a plurality of connecting posts 9 fixed at intervals along the length of the top surface of the lifting plate 8, four connecting posts 9 are provided on the lifting plate 8, and a positioning plate 10 is connected to the top of each connecting post 9. A positioning countersunk hole 11 is opened on the top surface of the positioning plate 10, the diameter of the positioning countersunk hole 11 is larger than the outer diameter of the sealing ring 1; a flange is fixed to the bottom of the connecting post 9, and the flange is fixed to the lifting plate 8 by screws to detachably fix the connecting post 9 to the lifting plate 8.

[0045] The pad is also fixed with a fixing seat 12 located outside the right upright plate 4. The top of the fixing seat 12 is connected to a horizontal plate 13 extending to the left and directly above the lifting plate 8. A thin rod 14 corresponding to the positioning plate 10 slides through the horizontal plate 13 along its length direction. The top of each thin rod 14 is connected to a displacement sensor 15 supported on the top surface of the horizontal plate 13.

[0046] Both sides of the movable seat 6 have through holes 16, and both through holes 16 of the movable seat 6 are matched with the strip-shaped square rod 5. Guide posts 17 are fixed on the fixed surface of the movable seat 6 and on the left and right sides of the lifting cylinder 7. Guide sleeves 18 are fixed on the bottom surfaces of the left and right ends of the lifting plate 8. The two guide sleeves 18 are respectively fitted on the two guide posts 17, and the guide posts 17 penetrate upward through the lifting plate 8.

[0047] The detection device also includes a controller, which is connected to the signal lines of the lifting cylinder 7 and four displacement sensors 15. The worker can control the upward extension or retraction of the piston rod of the lifting cylinder 7 through the controller, and at the same time, it can also receive the displacement signals sent by the displacement sensors 15.

[0048] The working process of this utility model is as follows:

[0049] S1, the worker took out four such... Figures 1-2 The sealing rings 1 to be tested are shown. Four sealing rings 1 are placed into the positioning countersunk holes 11 of the four positioning discs 10, respectively. Figure 12 As shown;

[0050] S2. The worker pushes the movable seat 6 to the right by hand. The movable seat 6 moves in a straight line to the right along the strip-shaped square rod 5. At the same time, the movable seat 6 drives the lifting cylinder 7, lifting plate 8, connecting column 9, and positioning plate 10 to move in a straight line to the right. The positioning plate 10 drives the sealing ring 1 inside it to move in a straight line to the right. When the movable seat 6 is blocked by the right-side vertical plate 4, the sealing ring 1 enters the thickness detection station. Figure 13 As shown, at this time, the right ends of the four sealing rings 1 are respectively located directly below the four thin rods 14;

[0051] S3. The worker controls the piston rod of the lifting cylinder 7 to extend upwards. The piston rod drives the lifting plate 8 to move upwards in a straight line. The lifting plate 8 drives the connecting column 9 and the positioning plate 10 to move upwards in a straight line simultaneously. The positioning plate 10 drives the sealing rings 1 inside it to move towards the bottom end of their corresponding thin rods 14. Figures 14-15 As shown;

[0052] When the piston rod of the lifting cylinder 7 is fully extended, if the displacement sensor 15 sends a displacement signal to the controller [the reason for sending the displacement signal is that the sealing ring 1 pushes the thin rod 14 upward, the thin rod 14 drives the displacement sensor 15 to move upward, thereby causing the displacement sensor 15 to send a displacement signal], it indicates that the thickness of the sealing ring 1 corresponding to the displacement sensor 15 is greater than the design thickness, and the worker judges the sealing ring 1 to be a defective product.

[0053] If the displacement sensor 15 does not send a displacement signal to the controller, it means that the thickness of the sealing ring 1 corresponding to the displacement sensor 15 is less than or equal to the design thickness. The worker judges the sealing ring 1 as a qualified product, thus realizing the detection of the thickness of four sealing rings 1 at one time.

[0054] S4. The specific operating procedures for removing non-conforming or conforming products are as follows:

[0055] The worker controls the piston rod of the lifting cylinder 7 to retract downwards. The piston rod drives the lifting plate 8 to move downwards. The lifting plate 8 drives the connecting column 9 and the positioning plate 10 to move downwards simultaneously. The positioning plate 10 drives the defective or qualified products downwards. After the piston rod of the lifting cylinder 7 is fully retracted, the worker pushes the moving seat 6 to the left by hand. The moving seat 6 drives the defective or qualified products to move in a straight line to the left simultaneously. When the moving seat 6 is blocked by the left vertical plate 4, the worker removes the defective or qualified products from the positioning plate 10.

[0056] S5. Workers can repeat steps S1 to S4 multiple times to complete the thickness test of all sealing rings 1 in the workshop.

[0057] As can be seen from steps S1 to S3, the worker only needs to first position the four sealing rings 1 in the positioning countersunk holes 11 of the four positioning discs 10 respectively; then, the moving seat 6 is placed against the right upright plate 4 so that the sealing rings 1 enter the thickness detection station; then, the piston rod of the lifting cylinder 7 is controlled to extend upward so that the four sealing rings 1 are respectively facing the four thin rods 14; then the worker judges whether the displacement sensor 15 sends an electrical signal to the controller to judge whether the thickness of the sealing ring 1 corresponding to the displacement sensor 15 meets the requirements, so as to quickly detect the thickness of the four sealing rings 1.

[0058] Therefore, it can be seen that this detection device is superior to... Figures 3-4 The detection method shown eliminates the need for workers to manually check the thickness of the sealing rings 1 one by one with vernier calipers 3. Instead, it quickly completes the detection of the thickness of four sealing rings 1. This not only greatly reduces the workload of workers, but also enables all sealing rings 1 in the workshop to be tested in a short time, thereby greatly improving the efficiency of the detection of the thickness of the sealing rings 1.
