Description

Technical Field

[0001] The present application relates to the technical field of component detection equipment, and in particular to a structure for detecting the pressing angle of an inch sleeve. Background Art

[0002] Existing parts, especially the more precise parts, need to be inspected for size, installation angle, installation position, etc. after production to ensure that the quality of the parts meets the standards.

[0003] like Figure 1 As shown, there is a component for automobiles, which includes a shell 20, one end of which is fixedly connected to a sleeve 30, and a bearing sleeve 40 is embedded in the sleeve 30. The sleeve 40 is pressed into the sleeve 30 manually or by machine during production, and the pressing angle of the sleeve 40 must be within a specified error range when the above-mentioned component is used to ensure the quality of the component.

[0004] When detecting the pressing angle of the above-mentioned inch sleeve 40, the existing detection method is mainly through manual measurement. However, manual detection usually requires locating the center of the circle before measurement. Since a center hole is opened in the center of the above-mentioned inch sleeve 40, it is more difficult to locate the center of the circle and it is easy to have deviations, resulting in errors in the process of manually directly measuring the pressing angle of the inch sleeve 40, thereby affecting the accuracy of subsequent measurement results and being inconvenient to use. Utility Model Content

[0005] In order to solve the above-mentioned problem that measurement errors are prone to occur when the inch sleeve is directly measured manually, which affects the accuracy of subsequent measurement results, the present application provides an inch sleeve press-in angle detection structure.

[0006] The present application provides a sleeve pressing angle detection structure, which adopts the following technical solution:

[0007] A structure for detecting an inch sleeve pressing angle, comprising a base and a positioning block, wherein the positioning block is arranged on the outside of the base, the positioning block is provided with an angle conversion component for converting the inch sleeve pressing angle to the positioning block deflection angle, and the base is provided with a detection component for detecting the offset of the positioning block.

[0008] By adopting the above technical solution, the positioning block is placed on the inch sleeve during use, and the deflection of the inch sleeve pressing angle is converted into the offset of the positioning block through the angle conversion component. Thereafter, the offset of the positioning block can be detected through the detection component, and the detection result obtained is the deflection of the inch sleeve pressing angle. The overall detection process is simple and convenient. Compared with the manual measurement method in the prior art, the measurement result is more accurate and more convenient to use.

[0009] Preferably, the angle conversion assembly includes a first positioning pin for positioning the central axis of the inch sleeve and a second positioning pin for positioning the side wall of the inch sleeve, the first positioning pin is fixed on the positioning block, two second positioning pins are provided, and the two second positioning pins are respectively located on both sides of the first positioning pin, and the second positioning pin is detachably connected to the positioning block.

[0010] By adopting the above technical solution, the center of the inch sleeve is positioned by the first positioning pin, and the side wall of the inch sleeve is positioned by the two second positioning pins, thereby forming three-point positioning. After that, the three-point positioning can be used to ensure that the angle of placement of the positioning block is the same as the pressing angle of the inch sleeve, thereby facilitating the subsequent detection of the angle offset of the positioning block.

[0011] Preferably, the detection assembly includes a mounting seat arranged on the base, a positioning rod fixed on the mounting seat, a detection rod sliding on the mounting seat, and a measuring piece arranged on the mounting seat for observing the sliding position of the detection rod, the detection rod is arranged parallel to the positioning rod, and the detection rod and the positioning rod are both arranged toward the end face of the positioning block.

[0012] By adopting the above technical solution, when in use, the positioning block is placed on the inch sleeve, so that one end of the positioning rod is in contact with the positioning block, and then the detection rod is pushed manually to slide. When one end of the detection rod is in contact with the positioning block, the sliding position of the detection rod can be judged by the measuring piece, so as to obtain the offset of the positioning block angle, and then whether the inch sleeve pressing angle is qualified can be determined according to the offset of the positioning block angle.

[0013] Preferably, the measuring member includes a detection block fixed on the mounting seat, the detection block is provided with a first detection surface and a second detection surface, a qualified interval is formed between the first detection surface and the second detection surface, and the detection block is provided with a sliding hole, and the detection rod passes through the mounting seat at one end away from the positioning block and slides in the sliding hole.

[0014] By adopting the above technical scheme, when the abutting end of the detection rod abuts against the positioning block during use, the detection end of the detection rod slides in the sliding hole. If the detection end of the detection rod is located within the qualified interval, it proves that the offset angle of the positioning block is qualified, that is, the inch sleeve press-in angle is qualified. If the detection end of the detection rod is located outside the qualified interval, it proves that the offset angle of the positioning block is unqualified, that is, the inch sleeve press-in angle is unqualified. The whole day's detection and judgment method is simple and convenient, which is conducive to use.

[0015] Preferably, an abutment plate is fixedly connected to the detection rod, a spring is sleeved on the detection rod, one end of the spring abuts on the abutment plate, the other end of the spring abuts on the mounting seat, and a sliding structure for allowing the mounting seat to slide is provided on the base.

[0016] By adopting the above technical solution, the sliding structure is used to realize the sliding of the mounting seat during use, so that the mounting seat gradually approaches the positioning block until one end of the detection rod abuts against the positioning block. At this time, the spring is in a compressed state, so that the elastic force of the spring on the abutment plate ensures that the detection end of the detection rod always abuts against the positioning rod during the detection process, thereby ensuring the accuracy of the detection rod's pressing angle on the inch sleeve. At the same time, compared with manual detection of the detection rod, it is more convenient to use.

[0017] Preferably, the sliding structure includes a slide rail fixed on the base, a slide seat sliding on the slide rail, and an abutment block fixed on the base, the mounting seat is fixed on the slide seat, two abutment blocks are provided, and the two abutment blocks are relatively arranged at two ends of the base.

[0018] By adopting the above technical solution, when in use, the mounting seat can be moved by manually pushing the slide seat to slide, and the sliding distance of the slide seat is limited by the abutment block to prevent the slide seat from slipping off the slide rail.

[0019] Preferably, a limiting component for limiting the position of the slide seat after sliding is provided on the base.

[0020] By adopting the above technical solution, when in use, the sliding seat is limited by the limiting component, thereby preventing the sliding seat from continuing to slide and affecting the measurement of the deflection angle of the positioning block, which is more convenient to use.

[0021] Preferably, the limiting assembly includes a fixed block fixed on the base, an abutment rod arranged on the fixed block, a shift rod rotatably connected to the slide seat, a handle is fixed to one end of the shift rod away from the slide seat, and when the shift rod is rotated to be parallel to the horizontal plane, the shift rod abuts against the abutment rod.

[0022] By adopting the above technical solution, the lever is driven to rotate by turning the handle during use. When the lever is rotated to be parallel to the upper surface of the slide, the abutment rod can be used to abut and limit the lever to prevent the slide from sliding in the opposite direction. When the lever is rotated to be perpendicular to the upper surface of the slide, the lever and the abutment rod are misaligned, thereby facilitating the staff to move the slide. The use is simple and convenient.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When in use, the first positioning pin and the second positioning pin are used in conjunction to realize the conversion of the inch sleeve pressing angle into the offset angle of the positioning block, and then the positioning rod and the detection rod are used in conjunction to realize the detection of the offset angle of the positioning block, thereby realizing the detection of the inch sleeve pressing angle, which is more convenient to use than the manual detection method, and also avoids the influence of the error generated during manual detection on the detection result;

[0025] 2. When in use, the detection assembly is driven to slide as a whole by manually sliding the slide seat, and the detection rod is driven by the spring to always abut against the positioning rod. The first detection surface and the second detection surface on the detection block are compared with the detection end surface of the detection rod, so as to quickly judge whether the offset angle of the positioning block is qualified, thereby achieving the purpose of judging whether the pressing angle of the inch sleeve is qualified;

[0026] 3. When in use, the slide is limited by the limit assembly to prevent the slide from sliding and affecting the detection assembly's detection of the inch sleeve's pressing angle. This also prevents the detection assembly from affecting the replacement of the inch sleeve when the inch sleeve needs to be replaced, making it more convenient to use.

[0034] The embodiment of the present application discloses a structure for detecting the pressing angle of an inch sleeve.

[0036] Reference Figure 2 and Figure 3 A limit assembly 10 is provided on the base 1, and the limit assembly 10 is used to limit the sliding seat 92 after sliding. There are two groups of limit assemblies 10, and the two groups of limit assemblies 10 are relatively arranged at two ends of the base 1. The limit assembly 10 includes a fixed block 101 and an abutment rod 102. The fixed block 101 is fixedly connected to the base 1 by bolts, and the abutment rod 102 is threadedly connected to the top of the fixed block 101. One end of the slide 92 is rotatably connected to a lever 103, and a handle 104 is welded to the end of the lever 103 away from the slide 92.

[0037] Reference Figure 2 and Figure 3 When the slide 92 slides to abut against the abutment block 93 during use, the staff rotates the handle 104 to make the handle 104 rotate to a horizontal state. At this time, the lever 103 abuts against the abutment rod 102, so that the abutment rod 102 and the abutment block 93 jointly limit the lever 103 to prevent the slide 92 from sliding. When the slide 92 needs to be moved, the lever 103 is rotated by turning the handle 104. When the lever 103 is rotated to be misaligned with the fixed block 101 and the abutment rod 102, the slide 92 can be moved. It is simple and convenient to use.

[0038] Reference Figure 2 and Figure 4The overall shape of the positioning block 2 is rectangular, and an angle conversion component 3 is provided on the positioning block 2. The angle conversion component 3 is used to convert the pressing angle of the inch sleeve 40 into the deflection angle of the positioning block 2. The angle conversion component 3 includes a first positioning pin 31 and a second positioning pin 32. The first positioning pin 31 is fixedly connected to the positioning block 2 by bolts. The bottom end of the first positioning pin 31 passes through the positioning block 2 and is inserted into the center hole of the inch sleeve 40. Two second positioning pins 32 are provided. The two second positioning pins 32 are respectively arranged on both sides of the first positioning pin 31. The bottom end of the second positioning pin 32 is inserted into the gap on one side of the inch sleeve 40, and the top end of the second positioning pin 32 is inserted into the positioning block 2.

[0039] Reference Figure 2 and Figure 4 When in use, first insert the second positioning pin 32 on the inch sleeve 40 to achieve preliminary positioning, then place the positioning block 2 on the inch sleeve 40, and make the top end of the second positioning pin 32 embedded in the positioning block 2, and then pass the bottom end of the first positioning pin 31 through the positioning block 2 and insert it into the center hole of the inch sleeve 40, thereby completing the connection between the positioning block 2 and the inch sleeve 40, so that through the coordinated use of the second positioning pin 32 and the first positioning pin 31, the pressing angle of the inch sleeve 40 is converted into the deflection angle of the positioning block 2, thereby facilitating the detection of the detection component 4.

[0040] Reference Figure 2 and Figure 5 The detection component 4 is used to detect the offset of the angle of the positioning block 2. The detection component 4 includes a mounting seat 41, a positioning rod 42, a detection rod 43 and a measuring piece 44. The mounting seat 41 is fixedly connected to the slide seat 92 by bolts, the positioning rod 42 is arranged at one end of the top of the mounting seat 41, and the detection rod 43 is arranged at the other end of the top of the mounting seat 41. One end of the positioning rod 42 is threadedly connected to the mounting seat 41, and the other end is arranged toward the positioning block 2. One end of the detection rod 43 is inserted into the mounting seat 41, and the other end is arranged toward the positioning block 2. The measuring piece 44 is used for users to observe and determine the offset of the angle of the positioning block 2.

[0041] Reference Figure 2 and Figure 5 When in use, first move the slide 92 to abut against the abutment block 93 at the left end of the base 1, and by turning the handle 104, rotate the lever 103 to abut against the abutment rod 102. At this time, one end of the positioning rod 42 abuts against one end of the side wall of the positioning block 2, and one end of the detection rod 43 abuts against the other end of the side wall of the positioning block 2. After that, the staff can judge the offset of the angle of the positioning block 2 by observing the measuring piece 44, thereby judging whether the pressing angle of the inch sleeve 40 is qualified.

[0042] Reference Figure 2 and Figure 5, one end of the detection rod 43 for abutting the positioning block 2 is set as an abutting end 431, and the other end is a detection end 432. An abutting plate 45 is integrally formed at the detection rod 43 near the abutting end 431. A spring 46 is sleeved on the detection rod 43, one end of the spring 46 abuts on the abutting plate 45, and the other end abuts against the side wall of the mounting seat 41; when in use, the detection end 432 of the detection rod 43 slides on the mounting seat 41, and the spring 46 is in a compressed state. When the positioning block 2 is detected by the detection rod 43, the elastic force of the spring 46 acts on the abutting plate 45, thereby ensuring that the abutting end 431 of the detection rod 43 is always abutted against the positioning block 2, thereby ensuring the accuracy of the detection component 4 in detecting the angle of the positioning block 2.

[0043] Reference Figure 2 and Figure 5 The measuring piece 44 includes a detection block 441, which is fixedly connected to the mounting seat 41 by bolts. A sliding hole 5 is provided on the detection block 441. The detection end 432 of the detection rod 43 passes through the mounting seat 41 and slides in the sliding hole 5. The detection block 441 is formed with a first detection surface 6 and a second detection surface 7, and a qualified interval 8 is formed between the first detection surface 6 and the second detection surface 7; when in use, the detection rod 43 moves under the extrusion of the positioning block 2, so that the detection end 432 on the detection rod 43 slides in the sliding hole 5. If the detection end 432 on the detection rod 43 is located in the qualified interval 8, it proves that the angle deflection of the positioning block 2 is within the error range, that is, it proves that the pressing angle of the inch sleeve 40 is qualified, otherwise it proves that the pressing angle of the inch sleeve 40 is unqualified.

[0044] The implementation principle of the embodiment of the present application is as follows: when in use, first fix the parts with the inch sleeve 40 installed, then insert the two second positioning pins 32 into the inch sleeve 40 respectively, and place the positioning block 2 on the inch sleeve 40, so that the top end of the second positioning pin 32 is embedded in the positioning block 2, and then the bottom end of the first positioning pin 31 passes through the positioning block 2 and is inserted into the center hole of the inch sleeve 40, so as to achieve three-point positioning of the inch sleeve 40, so that the pressing angle of the inch sleeve 40 is rotated to the placement angle of the positioning block 2; then push the slide 92 to slide close to the positioning block 2, so that the detection rod 43 abuts against the positioning block 2, continue to push the slide 92, the spring 46 is compressed, until the positioning rod 42 also abuts against the positioning block 2, By rotating the handle 104, the lever 103 is brought into contact with the abutment rod 102, so as to lock the slide seat 92. After that, the staff can judge whether the angle deviation of the positioning block 2 is within the error range by observing the position of the detection end 432 of the detection rod 43 in the sliding hole 5. That is, if the detection end 432 of the detection rod 43 is within the qualified interval 8, it is proved that the angle deviation of the positioning block 2 is within the error range, and thus it can be concluded that the pressing angle of the inch sleeve 40 is within the error range, that is, the pressing of the inch sleeve 40 is qualified. The overall detection process is simple and convenient, and compared with the method of directly manually detecting the pressing angle of the inch sleeve 40, it can avoid the influence of the error caused by manual detection on the detection result, thereby improving the detection accuracy and being more convenient to use.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
