Description

Technical Field

[0001] This utility model relates to the field of thickness gauges, and more specifically, to a thickness gauge with a limiting mechanism. Background Technology

[0002] A thickness gauge is a professional instrument used to accurately measure the thickness of materials or objects. It plays a key role in industrial production and quality inspection. It is suitable for accurately measuring the thickness of various materials such as plastic films, sheets, paper, and foils, ensuring that the produced sheets meet production requirements.

[0003] However, most thickness gauges for thin parts currently have the following problems:

[0004] I. In most existing thin-part thickness gauges, the material to be tested is placed on the worktable during use. The material is easily affected by external forces during testing, resulting in displacement or falling off, which affects the testing results and makes it inconvenient to limit the placement of the material.

[0005] Second, in existing thin-part thickness gauges, the positions of the detection components are mostly fixed. If the material is thick or thin, the detection components can easily affect the detection effect, and it is inconvenient to adjust and adapt the position of the equipment.

[0006] Therefore, we have made improvements to this and proposed a thickness gauge with a limiting mechanism. Utility Model Content

[0007] The purpose of this utility model is to address the current problems of inconvenience in limiting the placement of materials and inconvenience in adjusting and adapting the usage position of equipment.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A thickness gauge with a limiting mechanism is proposed to improve the above-mentioned problems.

[0010] The application is as follows:

[0011] The system includes a base plate, a worktable fixedly connected to the base plate, a connecting shaft rotatably connected to the worktable, a positioning box fixedly connected to the connecting shaft, a first spring fixedly connected inside the positioning box, a limit plate fixedly connected to the other end of the first spring, a locking block fixedly connected to the limit plate, a pressure plate fixedly connected to the limit plate, a gear fixedly connected to the connecting shaft, a rack meshing with the gear, a movable frame fixedly connected to the rack, a second spring fixedly connected to the movable frame, a pressure roller fixedly connected to the other end of the second spring, a guide rod fixedly connected to the pressure roller, the guide rod being slidably connected to the movable frame, a column fixedly connected to the base plate, a control panel mounted on the column, a connecting frame provided on the column, a slider fixedly connected to the connecting frame, the slider being slidably connected inside the column, a third spring fixedly connected inside the slider, a connecting plate fixedly connected to the other end of the third spring, an insert rod fixedly connected to the connecting plate, and positioning Velcro fixedly connected to the column and the insert rod.

[0012] As a preferred technical solution of this application, the first spring is symmetrically distributed on the upper and lower sides of the positioning box, and the first spring corresponds to the card block one by one through the limiting plate.

[0013] As a preferred technical solution of this application, the worktable is provided with slots at equal angles, and the connecting shaft is fixedly connected to the center of the positioning box and the gear.

[0014] As a preferred technical solution of this application, the bottom end face of the mobile frame is in contact with the top end face of the base plate, and the second spring is equidistantly distributed on the pressure roller.

[0015] As a preferred technical solution of this application, a pull rod is fixedly connected to the connecting plate, a test box is fixedly connected to the connecting frame, a displacement sensor is installed on the test box, and the width of the column is greater than the inner width of the connecting frame.

[0016] As a preferred technical solution of this application, a probe is installed on the displacement sensor, a pressure sensor is installed on the probe, a piston plate is fixedly connected to the pressure sensor, and the cross-section of the slider is "T" shaped.

[0017] As a preferred technical solution of this application, a gas supply pipe is fixedly connected to the test box, and a pressure regulator is installed at the other end of the gas supply pipe. The pressure regulator is installed on the control panel, and the length of the pull rod is greater than the length of the insertion rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] 1. Equipped with a movable frame; when limiting the detection of thin plates, the thin plate can be placed on the worktable, and the pressure plates on both sides of the positioning box are pressed to drive the limiting plate to move. The limiting plate can compress the first spring inside the positioning box. At the same time, the limiting plate drives the locking block to disengage from the slot of the worktable, which facilitates the rotation of the gear through the connecting shaft on the positioning box. The gear can push the racks on both sides to move inward. When the movable frame on the rack moves, the installed pressure roller can press the placed thin plate, and the protrusion of the thin plate can push the pressure roller to move upward. The pressure roller moves smoothly under the guidance of the guide rod, and the pressure roller can be pushed and pressed by the second spring to improve the limiting effect and prevent the placed thin plate from shifting and falling off.

[0021] 2. Equipped with a slider; when adjusting the position of the test box, the pull rod can be pulled to move the connecting plate. The connecting plate can compress the third spring, lifting the connecting plate and causing the positioning Velcro on the insert rod to detach from the positioning Velcro on the column. The slider is unobstructed and can move on the column. The slider can adjust the position of the connecting frame and the test box. Releasing the pull rod will push the connecting plate and insert rod to reset under the push of the third spring. The positioning Velcro on the insert rod can be stuck to the positioning Velcro inside the column for positioning, which is convenient for adjustment and adaptation according to the usage.

[0034] like Figure 1-6As shown, this embodiment proposes a thickness gauge with a limiting mechanism, including a base plate 1, a worktable 2 fixedly connected to the base plate 1, a connecting shaft 3 rotatably connected to the worktable 2, a positioning box 4 fixedly connected to the connecting shaft 3, a first spring 5 fixedly connected inside the positioning box 4, a limiting plate 6 fixedly connected to the other end of the first spring 5, a locking block 7 fixedly connected to the limiting plate 6, a pressure plate 8 fixedly connected to the limiting plate 6, a gear 9 fixedly connected to the connecting shaft 3, a rack 10 meshing with the gear 9, a moving frame 11 fixedly connected to the rack 10, and a second spring 12 fixedly connected to the moving frame 11.

A column 15 is fixedly connected to the base plate 1. A control panel 30 is installed on the column 15. A connecting frame 16 is provided on the column 15. A slider 17 is fixedly connected to the connecting frame 16. The slider 17 is slidably connected inside the column 15. A third spring 18 is fixedly connected inside the slider 17. A connecting plate 19 is fixedly connected to the other end of the third spring 18. An insertion rod 20 is fixedly connected to the connecting plate 19. A positioning Velcro 21 is fixedly connected to the column 15 and the insertion rod 20. Example

[0035] The solution in Example 1 will be further described below with reference to its specific working method.

[0036] like Figure 4 As shown, in a preferred embodiment, based on the above method, the first spring 5 is symmetrically distributed on the upper and lower sides of the positioning box 4. The first spring 5 corresponds one-to-one with the locking block 7 through the limiting plate 6, which can ensure that the locking blocks 7 on both sides can be engaged in the through hole of the worktable 2 to fix and limit the positioning box 4.

[0037] like Figure 4 As shown, in a preferred embodiment, based on the above method, the worktable 2 is further provided with slots at equal angles, and the connecting shaft 3 is fixedly connected to the center of the positioning box 4 and the gear 9, which can ensure that the gear 9 can be smoothly driven to rotate through the connecting shaft 3 when the positioning box 4 is rotated.

[0038] like Figure 4 As shown, in a preferred embodiment, based on the above method, the bottom end face of the movable frame 11 is in contact with the top end face of the base plate 1, and the second springs 12 are equidistantly distributed on the pressure roller 13, which can ensure that the multiple second springs 12 can smoothly push the pressure roller 13 to press down the material.

[0039] like Figure 6As shown, in a preferred embodiment, based on the above method, a pull rod 22 is fixedly connected to the connecting plate 19, a test box 23 is fixedly connected to the connecting frame 16, a displacement sensor 24 is installed on the test box 23, and the width of the column 15 is greater than the inner width of the connecting frame 16, so that the connecting frame 16 can slide on the column 15.

[0040] like Figure 6 As shown, in a preferred embodiment, based on the above method, a probe 25 is installed on the displacement sensor 24, a pressure sensor 26 is installed on the probe 25, a piston plate 27 is fixedly connected to the pressure sensor 26, and the slider 17 has a "T" shaped cross section, which can ensure that the "T" shaped slider 17 can slide within the column 15.

[0041] like Figure 6 As shown, in a preferred embodiment, based on the above method, a gas supply pipe 28 is fixedly connected to the test box 23, and a pressure regulator 29 is installed at the other end of the gas supply pipe 28. The pressure regulator 29 is installed on the control panel 30. The length of the pull rod 22 is greater than the length of the insertion rod 20, which can ensure that when the pull rod 22 is pulled, the insertion rod 20 can be driven to retract into the slider 17.

[0042] Specifically, when using this thickness gauge with a limit mechanism: (in conjunction with...) Figure 1-6 When using the equipment, the base plate 1 can be placed on the operating table. When limiting the detection of thin plates, the thin plate can be placed on the worktable 2. Pressing the pressure plates 8 on both sides of the positioning box 4 causes the limiting plate 6 to move. The limiting plate 6 can press the first spring 5 inside the positioning box 4. At the same time, the limiting plate 6 causes the locking block 7 to disengage from the slot of the worktable 2, which facilitates the rotation of the gear 9 through the connecting shaft 3 on the positioning box 4. The gear 9 can push the racks 10 on both sides to move inward, and the moving frame 11 on the racks 10 moves. When the pressure roller 13 is installed, it can press down on the thin plate. The protrusion of the thin plate can push the pressure roller 13 to move upward. The pressure roller 13 moves smoothly under the guidance of the guide rod 14. The pressure roller 13 can be pushed by the second spring 12 to press down on the thin plate, which can improve the limiting effect and prevent the thin plate from shifting and falling off. After the adjustment is completed, the pressure plate 8 is released. Under the push of the first spring 5, the limiting plate 6 and the locking block 7 are reset. The locking block 7 can be locked in the slot of the worktable 2 to perform positioning and prevent disengagement.

[0043] When adjusting the position of the test box 23, the pull rod 22 can be pulled to move the connecting plate 19. The connecting plate 19 can squeeze the third spring 18, lift the connecting plate 19 and cause the positioning hook and loop fastener 21 on the insertion rod 20 to detach from the positioning hook and loop fastener 21 on the column 15. The slider 17 is unobstructed and can slide on the column 15. The slider 17 can adjust the position of the connecting frame 16 and the test box 23. When the pull rod 22 is released, the connecting plate 19 and the insertion rod 20 are reset under the push of the third spring 18. The positioning hook and loop fastener 21 on the insertion rod 20 can be stuck to the positioning hook and loop fastener 21 inside the column 15 for positioning, which is convenient for adjustment and adaptation according to the usage.

[0044] The control panel 30 on the column 15 controls the operation of the equipment. The pressure gauge 29, connected to an external air pipe, can inflate the test chamber 23 through the air supply pipe 28. The air pressure pushes the piston plate 27, thereby moving the probe 25 and the pressure sensor 26 downward. When the piston plate 27 moves inside the test chamber 23, excess gas below the piston plate 27 can be discharged from the through holes of the test chamber 23 and the probe 25, improving the stability of the movement. The probe 25 is attached to the thin plate being tested. The air pressure pushes the pressure sensor 26 to move, which is blocked by the probe 25, thus generating pressure. The pressure sensor 26 can control the equipment to stop inflating through the control panel 30. The displacement sensor 24 can detect the distance the probe 25 moves downward. When testing the thin plate, the probe 25 can be moved downward to contact the worktable 2 first, and the distance data can be recorded. Then, the distance data at the contact with the thin plate is compared to obtain the thickness of the thin plate. The pressure sensor 26 used is a miniature pressure sensor LFC-05, and the displacement sensor 24 used is an FST-RX flexible magnetostrictive displacement sensor.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, as well as all technical solutions and improvements that do not depart from the spirit and scope of practicality, are covered within the scope of the claims of the present utility model.
