Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a pushing force detection mechanism. Background Art

[0002] The pushing force refers to the force required to push the nut out of the workpiece during the pushing process. The pushing force detection equipment is used to detect the pushing force and determine whether the workpiece is qualified. A thrust detector is mounted thereon and acts on the nut to read the magnitude of the pushing force.

[0003] Conventional pushing force detection equipment often directly contacts the thrust detector with the nut. When the cross-sectional size of the output end of the thrust detector is different from that of the nut, the thrust transmitted by the output end of the thrust detector cannot be evenly applied to the nut. In addition, when the thrust detector shakes, the output end of the thrust detector will also shake, resulting in non-fitting with the nut. Both of the above situations will lead to inaccurate pushing force detection results. Content of the Utility Model

[0004] In order to solve the defect of inaccurate pushing force detection results, the utility model provides a pushing force detection mechanism.

[0005] The technical solution adopted by the utility model is that a pushing force detection mechanism includes a first slider slidably connected to a frame. One side of the first slider has a thimble and a clamping tool for clamping a workpiece, and the other side has a thrust gauge and a driving component. The driving component is drivingly connected to the thrust gauge. The output ends of the thimble and the thrust gauge are both connected to the first slider.

[0006] Preferably, the output end of the thimble and / or the thrust gauge is detachably connected to the first slider.

[0007] Preferably, the thimble has a placement block and a protruding part. The protruding part is perpendicular to the placement block, and the placement block is connected to the first slider.

[0008] Preferably, the output ends of the thimble and the thrust gauge are coaxially arranged.

[0009] Preferably, the thrust gauge is connected to a second slider. Relative to the first slider, the second slider is arranged on one side of the thrust gauge and is slidably connected to the frame. The sliding direction of the second slider is the same as that of the first slider.

[0010] Preferably, the second slider has a protruding part, and the protruding part abuts against one end of the thrust gauge away from the output end.

[0011] Preferably, the driving component is drivingly connected to the second slider.

[0012] Preferably, the clamping tool includes a clamping part, and the clamping part clamps the workpiece in a direction perpendicular to the sliding direction of the first slider.

[0013] Preferably, the clamping tooling further includes an abutting portion which abuts against the end of the workpiece, and the workpiece is located between the abutting portion and the ejector pin.

[0014] Preferably, the clamping portion and / or the abutting portion are slidably connected to the machine frame in the sliding direction of the first slider.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The present application discloses a pushing force detecting mechanism. The first slider can slide on the machine frame. One side of the first slider is provided with an ejector pin for contacting the workpiece and a clamping tooling for clamping the workpiece, and the other side has an output end of a thrust meter and a driving component for generating a thrust. The first slider is loaded with the ejector pin and the output end of the thrust meter. The workpiece is clamped by the clamping tooling.

[0031] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will further describe in detail the implementation modes of the present utility model in conjunction with the accompanying drawings. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar components or components with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model, and cannot be construed as a limitation of the present utility model.

[0032] The present utility model discloses a pushing force detection mechanism. Please refer to Figures 1 to 5 , which includes a first slider 20 slidably connected to a frame 10. One side of the first slider 20 has a thimble 21 and a clamping tooling 40 for clamping a workpiece 60, and the other side has a thrust meter 30 and a driving component 50. The driving component 50 is drivingly connected to the thrust meter 30. The thimble 21 and the output end 31 of the thrust meter 30 are both connected to the first slider 20.

[0033] The first slider 20 can slide on the frame 10. On one side of the first slider 20, there is a thimble 21 for contacting the workpiece 60 and a clamping tooling 40 for clamping the workpiece 60. On the other side, there is an output end 31 of the thrust meter 30 and a driving component 50 for generating thrust. The thimble 21 and the output end 31 of the thrust meter 30 are loaded on the first slider 20. The workpiece 60 is clamped by the clamping tooling 40. The driving component 50 generates thrust and acts on the thrust meter 30, which is output from the output end 31 of the thrust meter 30. The output end 31 is then output to the thimble 21 through the first slider 20, and the thimble 21 finally acts on the workpiece 60. When the thimble 21 pushes the nut 61 in the workpiece 60, the first slider 20, the output end 31 of the thrust meter 30, and the thimble 21 will slide simultaneously. By selecting a thimble 21 that adapts to the cross-sectional size of the nut 61 in the workpiece 60, the problem that the cross-sectional size of the output end 31 of the thrust meter 30 does not match the cross-sectional size of the nut 61 can be solved. By arranging the output end 31 of the thrust meter 30 on the first slider 20, the output end 31 of the thrust meter 30 can move simultaneously with the thimble 21, and the situation that the output end 31 of the thrust meter 30 cannot fit with the nut 61 due to the vibration and offset of the thrust meter 30 will not occur. Compared with the prior art, a thrust detection mechanism disclosed in the present application can achieve the purpose of improving the accuracy of the thrust detection result.

[0034] Specifically, the output end 31 of the thrust meter 30 is often fixedly connected to the thrust meter 30 itself. Therefore, by driving the thrust meter 30 through the driving component 50, thrust can be output on the output end 31. The driving component 50 can be selected as manual driving and mechanical driving. When mechanical driving is selected, a mechanical component that can self-lock should be selected, or a self-locking structure should be added to a non-self-locking mechanical component. When the manual driving method is selected, the simplest method is to directly push the thrust meter 30 by hand to apply thrust. In addition, a rotating screw can also be used as the driving component 50. The rotating screw itself has a self-locking function and does not require the operator to continuously apply thrust. When in use, only by turning the rotating screw can thrust be applied to the nut 61. The more turns the rotating screw is turned, the greater the thrust applied.

[0035] Among them, the first slider 20 is slidably connected to the frame 10 through a slide rail 24, so that the sliding is smooth and the friction is smaller. In addition, through the arrangement of the slide rail 24, the movement direction of the thimble 21 can be better restricted, so that the thimble 21 will not shift and exactly apply thrust to the nut 61. Preferably, there are two slide rails 24, and the first slider 20 is arranged on the two slide rails 24. By slidingly connecting the first slider 20 to the frame 10 through the two slide rails 24, the stability of the first slider 20 is higher, and the thimble 21 is further prevented from shifting. In addition, a spare thimble 25 is provided on the side of the clamping tooling 40, which is convenient for replacing the thimble 21.

[0036] In other embodiments, the first slider 20 has a first part connected to the output part of the thrust gauge 30 and a second part connected to the remaining positions of the thrust gauge 30. This makes the connection to the thrust gauge 30 more reliable to prevent the thrust gauge 30 from deforming under its own gravity. In other embodiments, the thrust gauge 30 can be connected to the remaining positions of the thrust gauge 30 through the driving member 50, which can also achieve the purpose of making the connection of the thrust gauge 30 more firm and stable.

[0037] In some embodiments, please refer to Figures 1 to 5 , the output end 31 of the ejector pin 21 and / or the thrust gauge 30 is detachably connected to the first slider 20.

[0038] It should be noted that the output end 31 of the ejector pin 21 and / or the thrust gauge 30 is detachably connected to the first slider 20. By detachably connecting the ejector pin 21 to the first slider 20, the operator can select ejector pins 21 with different cross-sectional dimensions to be connected to the first slider 20, so as to adapt to nuts 61 with different cross-sectional dimensions. By detachably connecting the output end 31 of the thrust gauge 30 to the first slider 20, the operator can replace the thrust gauge 30 and replace the thrust gauge 30 with different sensitivities or different ranges for measuring the ejection force.

[0039] In some specific embodiments, the output end 31 of the ejector pin 21 and / or the thrust gauge 30 is disassembled in a direction perpendicular to the sliding direction of the first slider 20, and there is still no relative movement in the sliding direction. Such a setting can make the disassembly process simple and fast.

[0040] In other embodiments, the tail of the ejector pin 21 is provided with a thread, and the first slider 20 is provided with a threaded hole. The ejector pin 21 and the first slider 20 are threadedly connected to achieve detachable connection.

[0041] In some embodiments, please refer to Figure 1 and Figure 2 , the ejector pin 21 has a placement block 211 and a protruding part 212. The protruding part 212 is perpendicular to the placement block 211, and the placement block 211 is connected to the first slider 20.

[0042] Specifically, the ejector pin 21 has a placement block 211 and a protruding part 212. One end of the protruding part 212 is used to abut against the nut 61, and the other end is used to connect to the placement block 211. The protruding part 212 and the placement block 211 can be integrally formed to obtain higher structural strength. The area of the placement block 211 is larger, so it is easier to install on the first slider 20. The first slider 20 can be directly placed at the position where it needs to be installed on the first slider 20, or the placement block 211 and the first slider 20 can be magnetically connected.

[0043] In some embodiments, please refer toFigures 1 to 5 , the ejector pin 21 and the output end 31 of the thrust meter 30 are coaxially arranged.

[0044] It should be noted that, in order to better transfer the thrust to the nut 61, the output end 31 of the ejector pin 21 and the thrust meter 30 are coaxially arranged.

[0045] In some embodiments, please refer to Figures 1 to 5 , the thrust meter 30 is connected with a second slider 22. Relative to the first slider 20, the second slider 22 is arranged on one side of the thrust meter 30 and is slidably connected to the frame 10, and the sliding direction of the second slider 22 is the same as that of the first slider 20.

[0046] Specifically, the thrust meter 30 is connected with a second slider 22. The second slider 22 is arranged on the side where the thrust meter 30 is located relative to the first slider 20, and the sliding direction of the second slider 22 is the same as that of the first slider 20, so that the second slider 22 can move simultaneously with the first slider 20, thereby improving the stability of the thrust meter 30 and further improving the accuracy of the push force detection result.

[0047] In some specific embodiments, please refer to Figures 1 to 5 , the first slider 20 and the second slider 22 share a slide rail 24, so as to achieve the purpose of cost saving and accuracy improvement.

[0048] In some specific embodiments, please refer to Figures 1 to 5 , the second slider 22 has an extension part 23, and the extension part 23 abuts against one end of the thrust meter 30 far from the output end 31.

[0049] It should be noted that through the arrangement of the extension part 23, the thrust meter 30 can be fixed between the first slider 20 and the extension part 23, further improving the firmness of the installation of the thrust meter 30 and making it more stable during the working process.

[0050] In some specific embodiments, please refer to Figures 1 to 5 , the driving component 50 is drivingly connected to the second slider 22.

[0051] Among them, the driving component 50 is drivingly connected to the second slider 22 and does not directly act on the thrust meter 30. Therefore, when replacing thrust meters 30 of different types and sizes, there is no need to adjust the position of the driving component 50, making its assembly and adjustment process simpler.

[0052] In some embodiments, please refer to Figures 1 to 5 , the clamping tooling 40 includes a clamping part 41, and the clamping part 41 clamps the workpiece 60 in a direction perpendicular to the sliding direction of the first slider 20.

[0053] Specifically, the clamping tooling 40 is used to clamp the workpiece 60 to prevent the workpiece 60 from moving when the push nut 61 is pushed. The clamping tooling 40 includes a clamping portion 41. The clamping portion 41 clamps the workpiece 60 in a direction perpendicular to the first slider 20 to keep the workpiece 60 in a stable state, facilitating the testing of the pushing force.

[0054] In some specific embodiments, please refer to Figures 1 to 5 , the clamping portion 41 can be adjusted in size according to the width of the workpiece 60, so as to adapt to workpieces 60 of different widths and improve the adaptability. Specifically, the clamping portion includes clamping blocks 44 on both sides of the workpiece 60 in the width direction, and at least one of the clamping blocks 44 can move, and the workpiece 60 is clamped by the two clamping blocks 44.

[0055] In some specific embodiments, please refer to Figures 1 to 5 , the clamping tooling 40 further includes an abutting portion 42. The abutting portion 42 abuts against the end of the workpiece 60, and the workpiece 60 is located between the abutting portion 42 and the ejector pin 21.

[0056] Specifically, the clamping tooling 40 includes an abutting portion 42. The arrangement of the abutting portion 42 can make the workpiece 60 more stable and firm when placed and will not be pushed by the ejector pin 21.

[0057] In some more specific embodiments, please refer to Figures 1 to 5 , the clamping portion 41 and / or the abutting portion 42 are slidably connected to the frame 10 in the sliding direction of the first slider 20.

[0058] It should be noted that the clamping portion 41 and / or the abutting portion 42 can be slidably connected to the frame 10 to adapt to workpieces 60 of different lengths and improve the adaptability of the equipment. Among them, the clamping portion and / or the abutting portion 42 are provided with sliding blocks 43, and the frame 10 is provided with a slot 11.
