Description

Technical Field

[0001] This application relates to the field of equipment installation technology, and more specifically, to an installation tooling. Background Technology

[0002] Disc-type sleeves typically refer to parts mounted on shafts, such as bearings, flywheels, gears, and timing pulleys. Shaft sleeves generally have mounting holes, through which they are fitted onto the corresponding shaft. Some shaft sleeves are fixed to the corresponding rotating shaft using screws or nuts, thus constraining the shaft sleeve's position relative to the rotating shaft along its axial direction.

[0003] For disc-type components such as timing pulleys or gears, which typically require at least two mating parts, it is essential to ensure that the corresponding disc-type components are radially aligned with each other along the shaft during installation. Currently, to improve the assembly speed of disc-type components, axial limiting structures (such as shoulders or retaining rings) are generally installed on the shaft. By abutting the disc-type component against the axial limiting structure, the structure can position the disc-type component, thus allowing disc-type components mounted on different shafts to be radially aligned with each other. However, when it is necessary to adjust the installation position of the disc-type component along the axial direction of the shaft, the disc-type component needs to be separated from the axial limiting structure. This is usually done visually to determine whether the corresponding disc-type components are aligned, resulting in lower installation accuracy. Utility Model Content

[0004] In view of this, this application provides an installation fixture that can improve the installation accuracy of disc-type parts.

[0005] An embodiment of this application provides an installation fixture for installing a disc-shaped part onto a rotating shaft with an axial limiting structure. The installation fixture includes a calibration member with a machined surface and a receiving groove. The receiving groove is disposed on the machined surface along a first direction and extends through the machined surface along a second direction perpendicular to the first direction. The receiving groove is configured to receive the rotating shaft. The calibration member has a first positioning surface and a second positioning surface, which are spaced apart along the second direction. The first positioning surface is configured to abut against the axial limiting structure, and the second positioning surface is configured to abut against the disc-shaped part.

[0006] When installing disc-type parts, after fitting the disc-type part onto the rotating shaft, place the calibration piece onto the rotating shaft through the receiving groove, positioning the calibration piece between the disc-type part and the axial limiting structure. Then, move the disc-type part until it abuts against the second positioning surface and the first positioning surface abuts against the axial positioning structure. Then, lock the disc-type part. Finally, move the calibration piece along the first direction to disengage the receiving groove from the rotating shaft, thus removing the calibration piece. The other mating disc-type parts can be installed in the same manner using the above-mentioned installation tooling. With the axial limiting structures of each rotating shaft aligned radially with each other, the disc-type parts installed using the same installation tooling can be precisely aligned with each other, thereby improving the installation accuracy of each disc-type part.

[0007] In some embodiments of this application, the receiving groove includes a receiving portion, the inner wall of which is provided with a receiving surface, the receiving surface being shaped like the peripheral wall of the rotating shaft and configured to fit against the peripheral wall of the rotating shaft.

[0008] The receiving surface is shaped to fit against the circumferential wall of the rotating shaft. The receiving surface can position the rotating shaft, so that the calibration part can remain stable and fixed relative to the rotating shaft. This reduces the probability of the calibration part tilting when moving or locking disc-type parts, thereby further improving the installation accuracy of disc-type parts.

[0009] In some embodiments of this application, the receiving groove includes a guide portion that penetrates the processing surface and, along a first direction and toward the processing surface, the width of the guide portion gradually increases.

[0010] The guide section can increase the width of the opening of the receiving groove at the machined surface, thereby facilitating the placement of the calibration part onto the rotating shaft through the receiving groove.

[0011] In some embodiments of this application, the receiving groove includes a receiving portion, the inner wall of which is provided with a receiving surface, the receiving surface being configured to abut against the peripheral wall of the rotating shaft; the installation tooling also includes a mating component, the mating component being detachably disposed in the receiving groove, the mating component having a mating surface, the mating surface being configured to stop the rotating shaft toward the receiving surface.

[0012] After the calibration part is fitted onto the rotating shaft through the receiving groove, the mating part is installed into the receiving groove, so that the mating surface and the receiving surface abut against the opposite sides of the rotating shaft along the first direction. This constrains the position of the rotating shaft relative to the calibration part in the first direction, thereby enabling the calibration part to be stably connected to the rotating shaft. This eliminates the need to support the calibration part by hand, freeing up hands to install the corresponding disc-type parts.

[0013] In some embodiments of this application, one of the calibration member and the mating member is provided with a connecting protrusion, and the other of the calibration member and the mating member is provided with a connecting groove; when the mating member is inserted into the receiving groove along the first direction, the connecting protrusion can be aligned with the connecting groove along the third direction and inserted into the connecting groove, and the third direction intersects with the first direction.

[0014] After the connecting protrusion is inserted into the connecting groove, it can constrain the position of the mating part relative to the calibration part in the first direction, thereby making the mating part and the calibration part stably connected.

[0015] In some embodiments of this application, a guide surface is provided on the side of the connecting protrusion and / or connecting groove away from the mating surface along a first direction. The guide surface is configured to guide the connecting protrusion to move outward of the connecting groove as the mating member moves outward of the receiving groove along the first direction.

[0016] The guide surface guides the connecting protrusion, making it easier for the connecting protrusion to disengage from the connecting groove, thereby facilitating the removal of the mating part from the calibration part and making it easier to disassemble the mating part.

[0017] In some embodiments of this application, at least one of the mating part and the calibration part is provided with a deformation groove to facilitate elastic deformation of the corresponding calibration part or mating part.

[0018] By setting deformation grooves, elastic deformation can be easily achieved when the corresponding calibration part or mating part is subjected to force, thereby facilitating the movement of the connecting protrusion from the inner wall of the receiving groove into the connecting groove.

[0019] In some embodiments of this application, the calibration member is provided with a guide portion, and the mating member is provided with a mating portion, the mating portion being configured to slide and connect with the guide portion along a first direction.

[0020] The sliding engagement between the mating part and the guide part allows the connecting protrusion and the connecting groove to be aligned along the first direction, so that the connecting protrusion can be inserted into the connecting groove.

[0021] In some embodiments of this application, the calibration component includes a calibration block and a mating block. The mating block is detachably disposed on the calibration block. The calibration block has a first positioning surface and a second positioning surface. The mating block has a machined surface and a receiving groove.

[0022] The mating block is detachably mounted on the calibration block. Different mating blocks with different receiving groove sizes can be selected according to the diameter of the rotating shaft, thus making it applicable to rotating shafts of different diameters.

[0023] In some embodiments of this application, the calibration component includes a reference block and an adjustment block, the position of the adjustment block relative to the reference block along a second direction is adjustable; the reference block has a first positioning surface and a machining surface, the reference block is provided with a receiving groove, and the adjustment block has a second positioning surface.

[0024] By adjusting the position of the adjusting block relative to the reference block along the second direction, the distance between the first positioning surface and the second positioning surface along the second direction can be adjusted, thereby allowing the distance between the disc-type parts and the axial limiting structure after installation to be adjusted as needed.

[0034] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0036] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0037] Furthermore, the terms “first,” “second,” “third,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0038] An embodiment of this application provides an installation fixture for installing a disc-shaped part onto a rotating shaft with an axial limiting structure. The installation fixture includes a calibration member with a machined surface and a receiving groove. The receiving groove is disposed on the machined surface along a first direction and extends through the machined surface along a second direction perpendicular to the first direction. The receiving groove is configured to receive the rotating shaft. The calibration member has a first positioning surface and a second positioning surface, which are spaced apart along the second direction. The first positioning surface is configured to abut against the axial limiting structure, and the second positioning surface is configured to abut against the disc-shaped part.

[0039] When installing disc-type parts, after fitting the disc-type part onto the rotating shaft, place the calibration piece onto the rotating shaft through the receiving groove, positioning the calibration piece between the disc-type part and the axial limiting structure. Then, move the disc-type part until it abuts against the second positioning surface and the first positioning surface abuts against the axial positioning structure. Then, lock the disc-type part. Finally, move the calibration piece along the first direction to disengage the receiving groove from the rotating shaft, thus removing the calibration piece. The other mating disc-type parts can be installed in the same manner using the above-mentioned installation tooling. With the axial limiting structures of each rotating shaft aligned radially with each other, the disc-type parts installed using the same installation tooling can be precisely aligned with each other, thereby improving the installation accuracy of each disc-type part.

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] Reference Figure 1 and Figure 2This application provides an installation fixture 100 for assisting in the installation of disc-shaped parts. In some embodiments, the disc-shaped parts include one of gears, sprockets, timing pulleys, and rollers. In other embodiments, the disc-shaped parts may be other structural components for mounting to a rotating shaft.

[0042] Embodiments of this application also provide a conveying device 200, which is assembled using an installation fixture 100. The conveying device 200 includes a frame 21, a flow channel side plate 22, a coupling 23, a connecting shaft 24, a drive motor 25, and a conveying assembly 26. Two conveying assemblies 26 are provided, and the two conveying assemblies 26 are spaced apart along the width direction of the frame 21. The conveying assembly 26 includes synchronous pulleys 261, rotating shafts 262, and synchronous transmission belts 263. There are two synchronous pulleys 261 and two rotating shafts 262, with one rotating shaft 262 corresponding to one synchronous pulley 261. The two rotating shafts 262 are respectively rotatably located at both ends of the frame 21 along the length direction of the frame 21, and each synchronous pulley 261 is located on the corresponding rotating shaft 262. The synchronous transmission belt 263 is sleeved on the two corresponding synchronous pulleys 261 and tensioned. There are two connecting shafts 24, one of which is located at one end of the frame 21 and the other at the other end. The two ends of each connecting shaft 24 are connected to the corresponding rotating shaft 262 via couplings 23. The drive motor 25 is connected to the frame 21 and to one of the rotating shafts 262.

[0043] The drive motor 25 drives the rotating shaft 262 to rotate, which in turn rotates the synchronous pulley 261, thereby moving the synchronous transmission belt 263 and conveying material. Two flow channel side plates 22 are provided, each connected to one side of the frame 21 along its width. These two side plates stop the material on the synchronous transmission belt 263 along the width of the frame 21, thus constraining the material in that direction. In some embodiments, the coupling 23 can be considered as an axial limiting structure on the rotating shaft 262. In other embodiments, the flow channel side plate 22 can be considered as an axial limiting structure on the rotating shaft 262. In still other embodiments, the axial limiting structure can also be a shoulder or retaining ring, etc., provided on the rotating shaft 262.

[0044] In some embodiments, the mounting fixture 100 includes a calibration member 11, which has a machined surface 111, a first positioning surface 112, and a second positioning surface 113. The calibration member 11 is provided with a receiving groove 114, which is disposed on the machined surface 111 along a first direction X and extends through the machined surface along a second direction Y, which is perpendicular to the first direction X. In some embodiments, the calibration member 11 is generally disk-shaped, with the end walls of the calibration member 11 at both ends along its axial direction being the first positioning surface 112 and the second positioning surface 113, respectively, and a portion of the peripheral wall of the calibration member 11 being the machined surface 111. It is understood that the second direction Y is parallel to the axial direction of the calibration member 11, and the first positioning surface 112 and the second positioning surface 113 are spaced apart along the second direction Y; the first direction X is parallel to the radial direction of the calibration member 11. In other embodiments, the calibration member 11 may also be in the shape of a cuboid plate, with the sidewalls on both sides along its thickness direction being a first positioning surface 112 and a second positioning surface 113, respectively. One of the sidewalls of the calibration member 11 located between the first positioning surface 112 and the second positioning surface 113 is a machined surface 111. In other embodiments, the calibration member 11 may also be a structural member of other shapes. Figure 1 The dashed lines in the diagram are used to separate the machined surface 111 on the peripheral wall of the calibration part 11.

[0045] In some embodiments, the receiving groove 114 is configured to receive the rotating shaft 262; the first positioning surface 112 is configured to abut against the axial limiting structure on the rotating shaft 262, and the second positioning surface 113 is configured to abut against the disc-type part. In some embodiments, the disc-type part is a synchronous pulley 261. During the assembly of the above-mentioned conveying device 200, when installing one of the synchronous pulleys 261 of the conveying assembly 26, the synchronous pulley 261 is sleeved onto the rotating shaft 262, and the rotating shaft 262 is connected to the coupling 23. Then, the calibration member 11 is sleeved onto the rotating shaft 262 through the receiving groove 114 and the calibration member 11 is positioned between the synchronous pulley 261 and the coupling 23. Then, the synchronous pulley 261 is moved so that the synchronous pulley 261 abuts against the second positioning surface 113 and the first positioning surface 112 abuts against the coupling 23. Then, the synchronous pulley 261 is locked. Finally, the calibration member 11 is moved along the first direction X so that the receiving groove 114 is disengaged from the rotating shaft 262, and the calibration member 11 can be removed. By installing another synchronous pulley 261 of the same transmission assembly 26 in the same manner using the aforementioned installation fixture 100, the position of each synchronous pulley 261 relative to each shaft 262 can be made the same, thereby enabling the corresponding two synchronous pulleys 261 to be precisely aligned with each other, improving the installation accuracy of each synchronous pulley 261. At the same time, the corresponding synchronous transmission belt 263 can be parallel to the end face of the synchronous pulley 261 along the axial direction of the outer edge of the synchronous pulley 261, thereby reducing the probability of wear between the synchronous transmission belt 263 and the outer edge of the synchronous pulley 261.

[0046] In some embodiments, the receiving groove 114 includes a receiving portion 1141 and a guiding portion 1142, which are sequentially arranged along a first direction X. The guiding portion 1142 is located on the side of the receiving portion 1141 near the machining surface 111 and extends through the machining surface 111. In some embodiments, the receiving groove 114 further includes a connecting portion 1143, which is disposed between the receiving portion 1141 and the guiding portion 1142 and connects the receiving portion 1141 and the guiding portion 1142. In some embodiments, the inner wall of the receiving portion 1141 is provided with a receiving surface 1141a, which is shaped to conform to the peripheral wall of the rotating shaft 262 and configured to fit against the peripheral wall of the rotating shaft 262. In some embodiments, the width of the guiding portion 1142 gradually increases along the first direction X and toward the machining surface 111. For example, the guide portion 1142 is the rounded corners on both sides of the opening of the receiving groove 114 at the machining surface 111. It can be understood that the width of the guide portion 1142 refers to the distance between the rounded corners on both sides of the opening of the receiving groove 114.

[0047] In some embodiments, the receiving groove 114 is generally a "U"-shaped groove. It is understood that the receiving portion 1141 is the bottom of the receiving groove 114, and the guide portion 1142 is the opening of the receiving groove 114. In other embodiments, the connecting portion 1143 may be omitted, and the cross-section of the receiving groove 114 is generally semi-circular. In still other embodiments, the guide portion 1142 may be omitted, provided that the rotating shaft 262 can move relatively between the inside and outside of the receiving groove 114 when the calibrator 11 moves along the first direction X.

[0048] The guide portion 1142 can increase the width of the opening of the receiving groove 114 at the machining surface 111, thereby facilitating the fitting of the calibration part 11 to be fitted onto the rotating shaft 262 through the receiving groove 114; by making the receiving surface 1141a conform to the peripheral wall of the rotating shaft 262, the receiving surface 1141a can position the rotating shaft 262, so that the calibration part 11 can remain stably fixed relative to the rotating shaft 262, thereby reducing the probability of the calibration part 11 tilting when moving or locking disc-type parts, thereby further improving the installation accuracy of disc-type parts.

[0049] In other embodiments, the receiving portion 1141 may also be the inner wall of one side of the receiving groove 114 along its own width direction, and the receiving surface 1141a is provided on the inner wall of the receiving groove 114.

[0050] Reference Figure 3 and Figure 4In some embodiments, the mounting fixture 100 further includes a mating member 12, which is detachably disposed within a receiving groove 114. The mating member 12 has a mating surface 121 configured to stop the rotating shaft 262 towards a receiving surface 1141a. After the calibration member 11 is fitted onto the rotating shaft 262 through the receiving groove 114, the mating member 12 is inserted and installed into the receiving groove 114 along the first direction X, such that the mating surface 121 and the receiving surface 1141a abut against opposite sides of the rotating shaft 262 along the first direction X. This constrains the position of the rotating shaft 262 relative to the calibration member 11 in the first direction X, thereby ensuring a stable connection between the calibration member 11 and the rotating shaft 262. This eliminates the need to manually support the calibration member 11, freeing up the hands to install corresponding disc-type parts. It is understood that the end wall of the mating component 12, located along the first direction X and near the receiving surface 1141a, forms a mating surface 121. Optionally, the mating surface 121 is shaped to conform to the peripheral wall of the rotating shaft 262. In other embodiments, the receiving surface 1141a and / or the mating surface 121 can be a plane or a curved surface with a radius larger than that of the rotating shaft 262, as long as the receiving surface 1141a can constrain the rotating shaft 262 along the first direction X. Figure 3 The dashed line in the figure is used to represent the pivot 262.

[0051] In some embodiments, one of the calibrator 11 and the mating member 12 is provided with a connecting protrusion 122, and the other of the calibrator 11 and the mating member 12 is provided with a connecting groove 115; at least one of the mating member 12 and the calibrator 11 is provided with a deformation groove 123 to facilitate elastic deformation of the corresponding calibrator 11 or mating member 12. Exemplarily, the mating member 12 is provided with a connecting protrusion 122, the receiving groove 114 has a connecting groove 115 on the inner wall of one side along its width direction, and the mating member 12 is provided with a deformation groove 123.

[0052] In some embodiments, the deformation groove 123 extends through the mating member 12 along the second direction Y, and the deformation groove 123 passes through the end wall of the mating member 12 along the first direction X and toward the receiving surface 1141a. It can be understood that the deformation groove 123 passes through the mating surface 121. When installing the mating member 12, the mating member 12 can be squeezed to cause elastic deformation of the mating member 12, so that the connecting protrusion 122 is inserted into the receiving groove 114. Then, the mating member 12 is moved along the first direction X toward the receiving surface 1141a. When the connecting protrusion 122 and the connecting groove 115 are aligned along the third direction Z, the elastic deformation of the mating member 12 is restored, so that the connecting protrusion 122 is inserted into the connecting groove 115. This can constrain the position of the mating member 12 relative to the calibration member 11 in the first direction X, thereby making the mating member 12 and the calibration member 11 stably connected. In some embodiments, the third direction Z intersects the first direction X. For example, it can be understood that the third direction Z is parallel to the width direction of the receiving groove 114, and the third direction Z is perpendicular to both the first direction X and the second direction Y.

[0053] In some other embodiments, the deformation groove 123 may be omitted, and the elastic deformation of the calibration member 11 after being subjected to force may be used to allow the connecting protrusion 122 to be inserted into the receiving groove 114.

[0054] In other embodiments, the connecting protrusion 122 and the connecting groove 115 may be omitted, and the mating part 12 and the receiving groove 114 may be stably connected to each other by an interference fit.

[0055] In some embodiments, the inner wall of the connecting protrusion 122 and / or the connecting groove 115 is provided with a guide surface 1221 on the side away from the mating surface 121 along the first direction X. The guide surface 1221 is configured to guide the connecting protrusion 122 to move outward from the connecting groove 115 when the mating member 12 moves outward from the receiving groove 114 along the first direction X. Exemplarily, the connecting protrusion 122 is provided with a guide surface 1221 on the side away from the mating surface 121 along the first direction X. Along the third direction Z and away from the mating member 12, the distance between the guide surface 1221 and the mating surface 121 gradually decreases along the first direction X. Exemplarily, the guide surface 1221 is an arc-shaped surface. When the mating member 12 is pulled outward from the receiving groove 114 along the first direction X, the connecting groove 115 exerts a force on the guide surface 1221, causing the mating member 12 to undergo elastic deformation, thereby causing the connecting protrusion 122 to disengage from the connecting groove 115. The guide surface 1221 guides the connecting protrusion 122, making it easier for the connecting protrusion 122 to disengage from the connecting groove 115, thereby making it easier for the mating part 12 to disengage from the calibrating part 11, so as to facilitate the removal of the mating part 12.

[0056] In some embodiments, the connecting protrusion 122 has a guide surface 1222 on the side near the mating surface 121 along the first direction X. Along the third direction Z, away from the mating member 12, the distance between the guide surface 1222 and the mating surface 121 gradually increases along the first direction X. Exemplarily, the guide surface 1222 is an arc-shaped surface. When the mating member 12 is inserted into the receiving groove 114 along the first direction X, the inner wall of the receiving groove 114 can abut against the guide surface 1222, causing the mating member 12 to undergo elastic deformation under force, thereby moving the connecting protrusion 122 into the receiving groove 114, so that the mating member 12 can be inserted into the receiving groove 114. Optionally, the connecting protrusion 122 is generally semi-cylindrical, and the connecting groove 115 is shaped to resemble the connecting protrusion 122.

[0057] In some embodiments, the calibration member 11 is provided with a guide portion 116, and the mating member 12 is provided with a mating portion 124. The mating portion 124 is configured to slide and connect with the guide portion 116 along a first direction X. Exemplarily, the guide portion 116 is a strip-shaped groove, and the mating portion 124 is a strip-shaped protrusion. The guide portion 116 is disposed on the inner wall of the receiving groove 114. When the mating member 12 is inserted into the receiving groove 114 along the first direction X, the mating portion 124 is inserted into the guide portion 116 and moves along the guide portion 116, causing the connecting protrusion 122 and the connecting groove 115 to align along the first direction X, so that the connecting protrusion 122 can be inserted into the connecting groove 115. Simultaneously, the sliding engagement of the guide portion 116 and the mating portion 124 can constrain the position of the mating member 12 relative to the calibration member 11 in the second direction Y, thereby further improving the stability of the connection between the mating member 12 and the calibration member 11.

[0058] Reference Figure 5 In some embodiments, the calibration element 11 includes a calibration block 117 and a mating block 118. The mating block 118 is detachably disposed on the calibration block 117. The calibration block 117 has a first positioning surface 112 and a second positioning surface 113. The mating block 118 has a machined surface 111 and a receiving groove 114. In some embodiments, the calibration block 117 is generally disk-shaped, and the end walls at both ends of the calibration block 117 along its own axial direction are the first positioning surface 112 and the second positioning surface 113, respectively. The second direction Y is parallel to the axial direction of the calibration block 117.

[0059] In some embodiments, the calibration block 117 is provided with a mounting groove 1171, which extends through the second direction Y, and one end of the mounting groove 1171 along the first direction X is provided with a clearance opening 1171a, making the mounting groove 1171 approximately "U" shaped. A mating block 118 is inserted into the mounting groove 1171, and the end wall of the mating block 118 along the first direction X and near the clearance opening 1171a is a machined surface 111. Optionally, the mating block 118 is engaged with the mounting groove 1171 by an interference fit. By making the mating block 118 detachably provided on the calibration block 117, mating blocks 118 of different sizes that accommodate the groove 114 can be selected according to the diameter of the shaft 262, thereby making it suitable for shafts 262 of different diameters.

[0060] In some other embodiments, the connection between the mating block 118 and the calibration block 117 can also refer to the connection between the mating component 12 and the calibration component 11 in the above embodiments, which will not be repeated here. In some other embodiments, the mating block 118 and the calibration block 117 can also be detachably connected in other ways.

[0061] Reference Figure 6 and Figure 7In some embodiments, the calibration element 11 includes a reference block 11a and an adjustment block 11b, the position of the adjustment block 11b relative to the reference block 11a along the second direction Y is adjustable; the reference block 11a has a first positioning surface 112 and a machining surface 111, the reference block 11a is provided with a receiving groove 114, and the adjustment block 11b has a second positioning surface 113. In some embodiments, the reference block 11a and the adjustment block 11b are arranged sequentially along the second direction Y, the sidewall of the reference block 11a away from the adjustment block 11b along the second direction Y is the first positioning surface 112, and the sidewall of the adjustment block 11b away from the reference block 11a along the second direction Y is the second positioning surface 113. Alternatively, the calibration component 11 may further include a guide rod 11c. The reference block 11a is provided with a guide hole 11a1 along the second direction Y. One end of the guide rod 11c is connected to the adjustment block 11b, and the other end of the guide rod 11c is inserted into the guide hole 11a1. The guide rod 11c and the guide hole 11a1 slide and cooperate along the second direction Y, so that the distance between the adjustment block 11b and the reference block 11a along the second direction Y can be adjusted.

[0062] In some embodiments, the peripheral wall of the reference block 11a has a locking screw hole 11a2 communicating with the guide hole 11a1, and the axial direction of the locking screw hole 11a2 intersects the second direction Y; alternatively, the axial direction of the locking screw hole 11a2 is perpendicular to the second direction Y. The calibration component 11 also includes a locking screw 11d, which is threaded to the inner wall of the locking screw hole 11a2. By rotating the locking screw 11d, the locking screw 11d can abut against the guide rod 11c to fix the guide rod 11c, thereby fixing the adjusting block 11b relative to the reference block 11a, so that the distance between the first positioning surface 112 and the second positioning surface 113 along the second direction Y remains fixed. By adjusting the distance between the first positioning surface 112 and the second positioning surface 113 along the second direction Y, the distance between the installed disc-type part and the corresponding axial limiting structure can be adjusted as needed.

[0063] In some other embodiments, the locking screw 11d may be omitted, and the guide rod 11c and the guide hole 11a1 may be connected to the guide block by an interference fit, so that the length of the guide rod 11c inserted into the guide hole 11a1 can be adjusted as needed to adjust the distance between the first positioning surface 112 and the second positioning surface 113 along the second direction Y.

[0064] In other embodiments, the adjustment block 11b and the reference block 11a can also be slidably connected to each other by a slide rail or slide groove structure.
