[0039] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] In order to measure the specific value of the inner shuttle core groove height of the rotary hook, this embodiment provides a measuring tool for measuring the inner shuttle core groove height, such as... Figure 1 As shown, the inner shuttle here can also be understood as the shuttle frame M. For ease of understanding, this embodiment first describes the specific structure of the shuttle frame M:

[0041] Generally speaking, such as Figure 1 As shown, a vertically arranged spindle M2 is set at the center of the shuttle frame M. A cap end M21 is formed at the top of the spindle M2. A recessed annular groove M22 is formed between the cap end M21 and the spindle M2. A groove structure is formed between the outer peripheral wall of the shuttle frame M and the spindle M2. This groove structure is the aforementioned inner shuttle core groove M1. The height of the inner shuttle core groove M1 can be understood as the distance H between the bottom end face of the cap end M21 and the inner bottom wall of the core groove M1. The measuring tool provided in this embodiment is mainly used to measure the specific value of this distance.

[0042] like Figure 1-6 As shown, the measuring instrument provided in this embodiment includes a bracket 1, a dial indicator 2, two movable blocks, a measuring plate 4, and an elastic component 5. The following is a detailed description of each component:

[0043] like Figure 1 As shown, bracket 1 is mainly used as an installation carrier; for ease of explanation, in this embodiment, the height direction or vertical direction of bracket 1 is referred to as the first direction, and the horizontal direction perpendicular to the first direction is referred to as the second direction.

[0044] The dial indicator 2 is used as a specific measuring instrument. It generally consists of a vertical dial 22 with scales and a measuring rod 21 that can move axially. Different readings will be generated on the dial 22 depending on the distance of axial movement of the measuring rod 21.

[0045] The dial indicator 2 is mounted on the bracket 1, and the measuring rod 21 of the dial indicator 2 can move relative to the bracket 1 in a first direction;

[0046] The two movable blocks are designated as first movable block 31 and second movable block 32; the measuring rod 21, first movable block 31, and second movable block 32 are sequentially arranged on the bracket 1 along the first direction. That is, the measuring rod 21, first movable block 31, and second movable block 32 are arranged sequentially from top to bottom.

[0047] Moreover, both the first movable block 31 and the second movable block 32 can slide relative to the bracket 1 along the first direction, and the upper end of the first movable block 31 abuts against the end of the measuring rod 21 (the end here mainly refers to the lower end of the measuring rod 21).

[0048] The measuring plate 4 is positioned between the two first movable blocks 31 and the second movable block 32 and can move along the first direction.

[0049] In addition, the measuring plate 4 is also movable along a second direction between a first position and a second position; wherein the measuring plate at least partially constitutes the holding part 41.

[0050] like Figure 3 As shown, when the measuring plate 4 is in the first position, the cap end M21 of the spindle M2 of the shuttle frame M can pass through the holding part 41 in the first direction.

[0051] like Figure 4 As shown, when the measuring plate 4 is in the second position, the cap end M21 of the spindle M2 can hook onto the retaining part 41, which is equivalent to the bottom surface of the cap end M21 hooking onto the upper surface of the retaining part 41, thereby restricting the cap end M21 from disengaging downward from the retaining part 41.

[0052] The first position is equivalent to the loading station, and the second position is equivalent to the actual measurement station. That is, when the measuring plate is in the first position, the spindle M2 of the shuttle M to be measured is passed upward through the clamping part 41. Then, the measuring plate 4 is moved along the second direction to enter the second position. When the measuring plate enters the second position, the cap end M21 of the spindle M2 hooks against the clamping part 41, and the subsequent measurement can begin.

[0053] The elastic component 5 is mainly used to provide elastic force to push the two movable blocks to move so that the measuring plate 4 is clamped between the two movable blocks. Under the elastic force of the elastic component 5, the first movable block 31, the second movable block 32 and the measuring plate 4 as a whole have a tendency to move closer to the measuring rod 21 along the first direction, that is, the whole has a tendency to move upward.

[0054] In some embodiments, in order to enable the two movable blocks and the measuring rod 21 to move relative to the bracket 1 in a first direction, a channel extending in the first direction is provided inside the bracket 1, and the measuring rod 21, the first movable block 31, and the second movable block 32 are sequentially and movably inserted into the channel.

[0055] In addition, in order to enable the measuring plate 4 to slide relative to the bracket 1 along the first and second directions, in some embodiments, a movable opening 121 is provided on the side wall of the bracket 1, which extends through the bracket 1 along the second direction. The measuring plate 4 is inserted into the movable opening 121 and can move along the first and second directions within the movable opening 121.

[0056] In some embodiments, the elastic component 5 includes a first elastic element and a second elastic element:

[0057] like Figure 1 As shown, the first elastic element is used to provide a first elastic force to drive the first movable block 31 to move away from the measuring rod 21 in a first direction, that is, the first movable block 31 has a tendency to move downward; in some embodiments, the first elastic element may be a first spring 51, which is disposed in the channel and sleeved around the periphery of the first movable block 31, and pushes the first movable block 31 downward under its elastic force.

[0058] The second elastic element provides a second elastic force to drive the second movable block 32 to move closer to the measuring rod 21 along the first direction. That is, the second movable block 32 has an upward tendency. In some embodiments, the second elastic element may be a second spring 52, which is disposed in the channel and passes through the bottom periphery of the second movable block 32, causing the second movable block 32 to move upward under its elastic force.

[0059] It is worth noting that the elastic force of the second spring 52 is greater than that of the first spring 51. Thus, under the push of the elastic force of the second spring 52, the two movable blocks and the measuring plate 4 as a whole can overcome the elastic force of the first spring 51 and have an upward tendency.

[0060] In addition, to facilitate the later disassembly of the bracket 1 for maintenance or replacement of the components inside the bracket 1, in some embodiments, the bracket 1 includes a first frame 11 and a second frame 12, which are detachably connected along a first direction; for example, the ends of the first frame 11 and the second frame 12 are threaded together, or the ends of the first frame 11 and the second frame 12 are connected by bolts, etc.

[0061] In order for the cap end M21 of the spindle M2 of the shuttle frame M to pass through the retaining part 41 in the first direction when the measuring plate 4 is in the first position, and for the cap end M21 of the spindle M2 to hook onto the retaining part 41 when the measuring plate 4 is in the second position, the retaining part 41 is defined as follows:

[0062] Combination Figure 5As shown, the holding part 41 includes a first through hole 411 and a second through hole 412 that are sequentially arranged and connected along the second direction, with the first through hole 411 located on the left side and the second through hole 412 located on the right side.

[0063] The first through hole 411 can be a round hole. The diameter of the first through hole 411 is larger than the diameter of the cap end M21 of the mandrel M2. Here, the diameter of the cap end M21 refers to the maximum diameter of the cap end M21, ensuring that the cap end M21 of the mandrel M2 can pass through the retaining part 41 through the first through hole 411.

[0064] The second through hole 412 is an oblong hole, and the second through hole 412 extends along the second direction. The width of the second through hole 412 is smaller than the diameter of the cap end M21 of the mandrel M2. Here, the width of the second through hole 412 refers to the width that is horizontal and perpendicular to the second direction.

[0065] In addition, the retaining part 41 has a plate structure, and the thickness of the retaining part 41 in the first direction is less than the axial length of the annular groove M22 of the spindle M2, so as to ensure that the retaining part 41 can enter the annular groove M22 of the spindle M2.

[0066] In addition, in order to provide clearance for the cap end M21 of the mandrel M2, in some embodiments, in the first direction, there is a gap between the holding part 41 and the first movable block 31, that is, the middle part of the test plate protrudes downward by a distance to form the holding part 41.

[0067] In some embodiments, such as Figure 1 As shown, in order for the mandrel M2 to pass through the second movable block 32 normally in the vertical direction, the second movable block 32 has a through hole 321 for the mandrel M2 to pass through. When the measuring plate 4 is in the first position, the through hole 321 is axially aligned with the first through hole 411.

[0068] The specific measurement in this embodiment includes the following steps:

[0069] S1. Zeroing the dial indicator 2: This includes the following steps:

[0070] S11, Provide as Figure 6 The standard block B shown is basically the same as the standard shuttle M except that it has no peripheral wall. In the standard block, the height of the core groove is known, that is, the distance between the cap end ground and the bottom surface of the standard block is known.

[0071] S12. Move the measuring plate 4 so that it enters the first position, at which point the first through hole 411 and the through hole 321 on the second movable block 32 are aligned. Then, press the measuring plate 4 down slightly. Then, pass the cap end of the mandrel B1 of the standard block through the through hole 321 and the first through hole 411 from bottom to top.

[0072] S13. Move the measuring plate 4 to the left along the second direction, so that the measuring plate 4 gradually moves from the first position to the second position. During this process, the holding part 41 moves to the left relative to the cap end of the standard block and enters the second through hole 412.

[0073] S14. Release the measuring plate 4. Under the elastic force of the second spring 52, the second movable block 32 will be pushed to move upward. In turn, the second movable block 32 pushes the measuring plate 4 to move upward. Since the diameter of the cap end is greater than the thickness of the second through hole 412, the cap end cannot pass downward through the second through hole 412. Thus, as the holding part 41 moves upward, it will hook against the cap end and drive the entire standard block to move upward. Finally, the bottom wall of the standard block touches the bottom wall of the bracket 1. In this state, the dial indicator 2 is zeroed.

[0074] S2. After the dial indicator 2 is zeroed, remove the standard block. Specifically: first, move the measuring plate 4 to the right to enter the first position, and then pull the standard block down.

[0075] S3. Begin measuring the shuttle M to be measured (hereinafter referred to as the product): The measurement steps are basically similar to the zeroing steps of the standard block, specifically:

[0076] S31. Move the measuring plate 4 to the right to enter the first position;

[0077] S32, slightly press down the test plate 4, and pass the mandrel M2 of the product through the hole 321 and the first through hole 411 from bottom to top. Figure 3 The state shown.

[0078] S33. Move measuring plate 4 to the left to enter the second position. (Example) Figure 4 The state shown.

[0079] S34. Release the measuring plate 4. Under the elastic force of the second spring 52, push the second movable block 32 upward, which in turn drives the holding part 41 upward. The upward movement of the holding part 41 will hook the cap end M21 and pull the entire product upward until the bottom wall of the product abuts against the bottom wall of the bracket 1. At this time, read the reading on the dial indicator 2. It can be understood that the reading of the dial indicator 2 at this time is equivalent to the tolerance of the product compared with the standard part. That is, the height of the core groove M1 of the product is equivalent to the height of the core groove of the standard part plus the reading of the dial indicator 2.

[0080] In some embodiments, such as Figure 1 As shown, in order to position the measuring plate 4 and determine whether the measuring plate 4 has reached the first position or the second position, the measuring plate 4 is provided with a first stop 42 and a second stop 43 on both sides of the bracket 1; as Figure 3 As shown, when the first stop 42 abuts against the left wall of the bracket 1, the measuring plate 4 is in the first position; as Figure 4As shown, when the second stop 43 abuts against the right wall of the bracket 1, the measuring plate 4 is in the second position.

[0081] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.

[0082] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0083] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
