Description

Technical Field

[0001] This application relates to the field of runout measurement fixtures, specifically to fixtures that can quickly measure bolt runout in batches. Background Technology

[0002] Currently, most bolt runout measurements require the use of a coordinate measuring machine (CMM). Before using the CMM, operators typically need to manually adjust the clamping tools to secure the bolt. To prevent bolt misalignment during measurement, this securing method is usually quite tight, requiring significant manual force. This not only inconveniences the measurement process but also prolongs it.

[0003] Furthermore, if the clamping tool tightens the bolt too much, the bolt and plug will be difficult to release quickly. As a result, when there are many types of bolts to be measured, the entire measurement process will be further prolonged, thus affecting the overall measurement efficiency. Utility Model Content

The elastic element is configured to generate elasticity with one end connected to the passive stage and the other end connected to the driving stage. The display component is connected to the driving stage and has a retractable drive end connected to the end of the passive stage away from the measuring head. The display component is configured to generate corresponding runout measurement information by means of the retraction and extension of the drive end.

[0010] According to one embodiment of this application, the driving platform forms a moving part closer to the fixture body, and the fixture body forms a limiting channel closer to the driving platform. The extending direction of the limiting channel is parallel to the moving direction of the driving platform, and the moving part is configured to cooperate with the limiting channel so that the driving platform moves on the fixture body.

[0021] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0022] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] refer to Figures 1 to 4 A preferred embodiment of the present application of a gauge for rapidly and in batches measuring bolt runout will be described in detail below. The gauge is used to measure the end face runout at the head position of a bolt 90. The gauge includes a gauge body 10, a material holding component 20 and a measuring component 30.

[0025] Specifically, the material-fixing component 20 is rotatably disposed on the fixture body 10, and the material-fixing component 20 has a threaded hole 201 of a predetermined size in the middle to match the thread of the bolt 90. That is to say, the bolt 90 can be directly fixed to the threaded hole 201 of the material-fixing component 20 by means of threaded connection, thereby providing convenience for workers to quickly fix the bolt 90.

[0026] The measuring assembly 30 includes a measuring head 31, a passive stage 32, a driving stage 33, an elastic element 34, and a display member 35, wherein the measuring head 31 is disposed at one end of the passive stage 32. The passive stage 32 is movably connected to the driving stage 33. The driving stage 33 is movably connected to the gauge body 10 such that the front end of the measuring head 31 abuts against the head end face of the bolt 90. The elastic element 34 is configured to form an elastic force such that one end is connected to the passive stage 32 and the other end is connected to the driving stage 33. The display member 35 is connected to the driving stage 33, and the display member 35 is further provided with a retractable transmission end 351 connected to the end of the passive stage 32 away from the measuring head 31, and the display member 35 is configured to generate corresponding runout measurement information by means of the extension and retraction of the transmission end 351.

[0027] Those skilled in the art will understand that the measuring head 31 can be moved to a predetermined position by moving the driving platform 33 on the gauge body 10, and the bolt 90 gradually abuts against the front end of the measuring head 31 during the process of being connected to the threaded channel 201 of the material fixing member 20. At this time, the operator can rotate the rotating disk 21 to make the bolt 90 rotate synchronously with the rotating disk 21, so that the front end of the measuring head 31 can move relative to the end face of the bolt 90 head to perform a runout measurement operation.

[0028] It should be further explained that when the protruding part at the end face of the bolt 90 is moved past by the front end of the measuring head 31, the protruding part of the bolt 90 forms a structural constraint, causing the measuring head 31 to gradually move a predetermined distance toward the position of the material fixing member 20 during relative movement. This causes the passive stage 32 to be driven to move the predetermined distance along with the measuring head 31. At this time, the transmission end 351 of the display member 35 is stretched toward the position of the material fixing member 20 by a predetermined length. Thus, the display member 35 can generate corresponding jump measurement information based on the stretching length of the transmission end 351.

[0029] Similarly, when the head end face of the bolt 90 has a recessed portion that is moved past by the front end of the measuring head 31, the passive stage 32 is driven to move away from the fixed material member 20 to the driving stage 33 due to the elastic force formed by the elastic element 34. This causes the transmission end 351 of the display member 35 to no longer be stretched by the passive stage 32 and to shrink to a predetermined length. At this time, the display member 35 forms corresponding jump measurement information according to the shrinkage length of the transmission end 351.

[0030] It is worth mentioning that when the measuring head 31 passes over the protruding part of the bolt head 90, the elastic force formed by the elastic element 34 can drive the passive table 32, thereby ensuring that the measuring head 31 is driven by the passive table 32 and always keeps in contact with the end face of the bolt head 90 during the rotation of the fixed material component 20, so as to continue to perform jump measurement operations on other positions of the end face of the bolt head 90.

[0031] In this way, not only can each of the bolts 90 be quickly connected to the material fixing component 20, but the measuring component 30 can also perform measurement runout operations on all positions of the head end face of each bolt 90, thereby improving the overall measurement efficiency.

[0032] Preferably, the measuring head 31 has a rollable part 311 at its front end to abut against the end face of the bolt head 90. It is understood that the rollable part 311 can be configured as a ball bearing, thereby allowing the measuring head 31 and the bolt 90 to change from a sliding movement mode to a rolling movement mode, reducing mutual friction and facilitating mutual movement between the two.

[0033] In one embodiment, such as Figure 3As shown, the passive platform 32 forms a moving channel 3201 near the driving platform 33. The extending direction of the moving channel 3201 is parallel to the moving direction of the passive platform 32. Correspondingly, the driving platform 33 forms a protrusion 331 near the passive platform 32. The protrusion 331 is configured to cooperate with the moving channel 3201 so that the passive platform 32 moves on the driving platform 33.

[0034] It is understood that the movable channel 3201 is used to restrict the movement of the passive stage 32, thereby causing the passive stage 32 to move onto the driving stage 33 in a predetermined manner. Similarly, in a modified embodiment, the movable channel 3201 is configured to be formed by the driving stage 33, and the protrusion 331 is configured to be formed by the passive stage 32, thus allowing the passive stage 32 to move onto the driving stage 33 in a predetermined manner as well.

[0035] In one embodiment, such as Figure 4 As shown, the driving platform 33 forms a moving part 332 near the inspection fixture body 10. Correspondingly, the inspection fixture body 10 forms a limiting channel 101 near the driving platform 33. The extending direction of the limiting channel 101 is parallel to the moving direction of the driving platform 33, and the moving part 332 is configured to cooperate with the limiting channel 101 so that the driving platform 33 moves on the inspection fixture body 10.

[0036] It is understood that the limiting channel 101 is used to restrict the movement of the drive platform 33, thereby causing the drive platform 33 to move on the fixture body 10 in a predetermined manner. Similarly, in a modified embodiment, the limiting channel 101 is configured to be formed by the drive platform 33, and the moving part 332 is configured to be formed by the fixture body 10, so that the drive platform 33 can also move on the fixture body 10 in a predetermined manner.

[0037] Preferably, the direction in which the elastic element 34 generates the elastic force is set to be oriented toward the moving direction of the passive platform 32, so that the elastic element 34 generates the elastic force according to a predetermined deformation mode. Preferably, the elastic element 34 is configured as a spring.

[0038] Preferably, the display component 35 is configured as a dial indicator to display the measured runout information of the bolt 90. For example, if the pointer swing amplitude of the dial indicator is less than 0.03mm, it means that the runout measurement of the bolt 90 is qualified.

[0039] Preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, the inspection fixture body 10 includes a vertical wall 11 and a horizontal wall 12. Preferably, the vertical wall 11 is fixedly connected to one end of the horizontal wall 12, and the vertical wall 11 extends a predetermined length in the vertical direction. The horizontal wall 12 extends a predetermined length in the horizontal direction in a manner that allows it to remain perpendicular to the vertical wall 11.

[0040] It is worth mentioning that the limiting channel 101 is disposed on the horizontal wall 12 for the movement of the driving platform 33 of the measuring component 30. The material fixing component 20 is rotatably disposed on the vertical wall 11.

[0041] In a preferred embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the material positioning component 20 includes a rotating disk 21 and a positioning member 22, wherein the rotating disk 21 is rotatably connected to the vertical wall 11 of the inspection fixture body 10. The positioning member 22 is detachably connected to the rotating disk 21. The threaded channel 201 is provided to at least partially penetrate the positioning member 22 and is located in the direction of the axis of the rotating disk 21.

[0042] Preferably, the rotating disk 21 further has an anti-slip structure 211. Preferably, the anti-slip structure 211 is positioned to surround the circumference of the rotating disk 21, thereby facilitating direct rotation of the rotating disk 21 by the operator. This allows the bolt 90 connected to the threaded hole 201 to be driven and rotate with the rotating disk 21 for measurement runout operation. In one embodiment, the anti-slip structure 211 is knurled.

[0043] Furthermore, the inspection tool for rapidly and in batches measuring bolt runout also includes an adjustment component 40, which is used to adjust the position of the measuring head 31 of the measuring assembly 30 so that the front end of the measuring head 31 can contact the end face of the bolt 90 head position connected to the material setter 20.

[0044] Preferably, the adjusting member 40 includes a clamping block 41 and a locking member 42, wherein one end of the clamping block 41 is connected to the passive stage 32, and the other end of the clamping block 41 is provided with a pair of relatively movable clamping arms 411, and the two clamping arms 411 are arranged opposite to each other and spaced apart to form an adjustable clamping opening 4101, the size of which is set to adapt to the size of the measuring head 31. The locking member 42 is movably connected to both clamping arms 411 simultaneously, so that the two clamping arms 411 can adjust the size of the clamping opening 4101 by relative movement.

[0045] Understandably, when the front end of the measuring head 31 is not at the same height as the head end face of the bolt 90, the locking member 42 is moved to increase the clamping jaw 4101 by moving the two clamping arms 411 relatively away from each other. This allows the operator to manually lift the measuring head 31 so that the front end of the measuring head 31 is at the same height as the head end face of the bolt 90. At this time, the locking member 42 can be moved again to move the two clamping arms 411 relatively close to each other so that the clamping jaw 4101 is reduced to fit the size of the measuring head 31. That is, the measuring head 31 is clamped at a predetermined position that can contact the head end face of the bolt 90.

[0046] Preferably, the locking element 42 is configured as a screw, which is threadedly connected to both clamping arms 411.

[0047] In a modified embodiment, the material-fixing member 20 is further movably disposed on the vertical wall 11 along the extending direction of the vertical wall 11 of the gauge body 10, thereby enabling the bolt 90 to actively move toward the measuring head 31 of the measuring assembly 30, so that the front end of the measuring head 31 can contact the end face of the bolt 90 head. In other words, the rotating disk 21 of the material-fixing member 20 is movably disposed on the vertical wall 11 along the extending direction of the vertical wall 11.

[0048] Furthermore, the gauge for rapidly batch measuring bolt runout also includes a stopping component 50. Preferably, the stopping component 50 includes an adjusting member 51 and an anti-slip block 52. Preferably, the driving platform 33 forms a transfer channel 3301 that extends through itself and faces the limiting channel 101, and the adjusting member 51 is movably connected to the transfer channel 3301. The anti-slip block 52 is connected to the front end of the adjusting member 51, and the size of the anti-slip block 52 is set to be smaller than the inner diameter of the limiting channel 101. Thus, when the adjusting member 51 moves in the transfer channel 3301, the anti-slip block 52 is configured to move in the limiting channel 101 to approach and move away from the bottom wall forming the limiting channel 101.

[0049] It is understandable that when the adjusting member 51 is moved to bring the anti-sliding block 52 closer to the bottom wall forming the limiting channel 101, the anti-sliding block 52 can directly abut against the bottom wall forming the limiting channel 101. At this time, the driving platform 33 is able to stay at a predetermined position due to the combined resistance of the moving part 332 and the anti-sliding block 52, so as to perform adjustment and measurement work. However, when the adjusting member 51 is moved to move the anti-sliding block 52 away from the bottom wall forming the limiting channel 101, only the moving part 332 of the driving platform 33 can contact the bottom wall forming the limiting channel 101, thus reducing the resistance to the movement of the driving platform 33, thereby allowing the driving platform 33 to be moved easily. Specifically, as shown in the figure... Figure 4 As shown.

[0050] Preferably, the passive platform 32 forms a waist-shaped window 3202 that extends through itself to communicate with the supply channel 3301, and the supply channel 3301 is configured to pass through the protrusion 331. The rear end of the adjusting member 51 extends radially outward to form a step 511 that can be located in the waist-shaped window 3301. The cross-sectional diameter of the step 511 is set to be larger than the inner diameter of the supply channel 3301 and smaller than the inner diameter of the waist-shaped window 3202. Thus, when the passive platform 32 moves a predetermined distance on the driving platform 33, the inner wall of the waist-shaped window 3202 can be abutted by the step 511, making it difficult for the passive platform 32 to detach from the driving platform 33.

[0051] Preferably, the adjusting member 51 is configured as a screw, and the feed channel 3301 of the drive platform 33 is configured as a threaded channel to cooperate with the screw, so that the anti-slip block 52 can move relatively closer to and away from the bottom wall forming the limiting channel 101.

[0052] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
