Description

Technical Field

[0001] This disclosure belongs to the field of mechanical parts installation technology, and specifically relates to a positioning device. Background Technology

[0002] A bearing is a component used to support a rotating shaft and reduce the coefficient of friction during its movement. In use, a bearing is typically fitted over the rotating shaft with an interference fit.

[0003] In related technologies, when a rotating shaft is press-fitted into the inner bore of a bearing, a positioning device is generally required. During pressing, the bearing is fixed by the positioning device, and then the rotating shaft is pressed into the inner bore of the bearing through a pressing structure. The positioning device is generally a clamping tool. The positioning device includes a fixed base, a threaded rod, and two oppositely arranged arc-shaped plates. The two arc-shaped plates are movably located on the fixed base and can move relative to each other or away from each other. The two arc-shaped plates are threadedly connected to the threaded rod, and the threads of the two arc-shaped plates have opposite directions of rotation. When it is necessary to position the bearing, the bearing is placed between the two arc-shaped plates, and then the threaded rod is controlled to rotate, causing the two arc-shaped plates to move closer together and fit against the outer wall of the bearing, thus achieving the clamping and positioning of the bearing.

[0004] However, when positioning the bearing, the above positioning device can only apply force to the opposite sides of the bearing through the arc-shaped plate, which makes the force on the bearing circumferentially uneven, thus affecting the coaxiality of the bearing and the shaft, and consequently affecting the assembly effect. Summary of the Invention

[0005] This disclosure provides a positioning device that can improve the assembly effect between the bearing and the shaft. The technical solution is as follows:

[0006] This disclosure provides a positioning device, which includes a support platform and a clamping assembly. The clamping assembly includes a rotating disk, a plurality of clamping members, and a plurality of connecting members arranged corresponding to the plurality of clamping members. The rotating disk is rotatably located on one side of the support platform. The plurality of clamping members are arranged at intervals along the circumference of the rotating disk and are all partially located in the support platform. Each of the plurality of clamping members is capable of moving radially along the rotating disk. The plurality of connecting members and the rotating disk are both movably located in the support platform, and each of the plurality of connecting members is movably connected to the corresponding clamping member and the rotating disk. The connecting member is used to drive the corresponding clamping member to move when the rotating disk rotates.

[0008] In another implementation of this disclosure, the support platform is provided with a sliding groove corresponding to each of the plurality of clamping members, the length direction of the sliding groove being the radial direction of the disk body; the clamping member includes a clamping block and a slider, the clamping block being located on the side of the slider away from the rotating plate along the axial direction of the rotating disk, and the clamping block being connected to the slider; the slider is movably located in the corresponding sliding groove and is in contact with the groove wall of the corresponding sliding groove.

[0009] In another implementation of this disclosure, the clamping member further includes a pressing plate and a plurality of first elastic members. The pressing plate is located on one side of the clamping block in a radially inward direction along the rotating disk. The plurality of first elastic members are spaced apart between the pressing plate and the clamping block, and both ends of each of the plurality of first elastic members are connected to the pressing plate and the clamping block, respectively.

[0010] In another implementation of this disclosure, the clamping block has a plurality of spaced guide holes that extend radially along the rotating disk; the clamping member further includes a plurality of guide rods arranged in a one-to-one correspondence with a plurality of first elastic elements, the plurality of guide rods corresponding one-to-one with the plurality of guide holes, each of the plurality of guide rods being located within a corresponding first elastic element, and one end of the guide rod being movably located within a corresponding guide hole, and the other end being connected to the extrusion plate.

[0011] In another implementation of this disclosure, a nut is embedded in the support platform; the positioning device further includes a lateral adjustment assembly, which includes a frame, a lateral drive member, and a lateral adjustment rod. The frame is fitted over the support platform, the lateral drive member is located outside the frame and connected to the frame, one end of the lateral adjustment rod is connected to the lateral drive member, and the other end of the lateral adjustment rod is located inside the frame and threadedly connected to the nut of the support platform. The length direction of the lateral adjustment rod is perpendicular to the axial direction of the rotating disk.

[0012] In another implementation of this disclosure, the positioning device further includes a longitudinal adjustment assembly, which includes a base, a longitudinal drive member, a longitudinal adjustment rod, and an adjustment block. The base is located on one side of the frame. The longitudinal drive member is located on the base and connected to it. One end of the longitudinal adjustment rod is connected to the longitudinal drive member, and the other end of the longitudinal adjustment rod is rotatably located inside the base. The longitudinal drive member is used to drive the longitudinal adjustment rod to rotate about itself as an axis. The length direction of the longitudinal adjustment rod is perpendicular to the length direction of the transverse adjustment rod. The adjustment block is sleeved on the longitudinal adjustment rod and threadedly connected to it. The adjustment block is connected to the frame.

[0013] In another implementation of this disclosure, the positioning device further includes a protective component, which includes a bracket, a protective cover, and a protective drive member. The bracket is located outside the base and is connected to the base. The protective cover is located between the bracket and the support platform along the axial direction of the rotating disk and is movably connected to the bracket. The protective drive member is located on the side of the bracket away from the support platform and is connected to the bracket. The protective drive member is connected to the protective cover and is used to drive the protective cover to move along the axial direction of the rotating disk, so that the protective cover closes the clamping assembly after the clamping assembly clamps the bearing.

[0014] In another implementation of this disclosure, the protective cover includes a pressure cap, a protective frame, and a plurality of second elastic members. The pressure cap is movably inserted into the protective frame and, together with the protective frame, defines a protective space for accommodating the clamping assembly. The plurality of second elastic members are spaced circumferentially between the pressure cap and the protective frame, with both ends of the second elastic members connected to the pressure cap and the protective frame, respectively.

[0016] The beneficial effects of the technical solutions provided in this disclosure are:

[0017] Since the clamping assembly includes a rotating disk, multiple clamping elements, and multiple connecting elements arranged one-to-one with the clamping elements, the rotating disk provides a mounting base for the clamping elements, while the connecting elements connect the clamping elements to the rotating disk. Thus, when a bearing needs to be clamped, the bearing can be placed on the support platform first, and then the rotating disk is controlled to rotate. After the rotating disk rotates, the multiple clamping elements can move synchronously inward along the radial direction of the rotating disk under the action of the connecting elements, thereby clamping the bearing. Conversely, when the bearing needs to be released, the rotating disk is controlled to rotate in the opposite direction. After the rotating disk rotates in the opposite direction, the multiple clamping elements can move synchronously outward along the radial direction of the rotating disk under the action of the connecting elements, thereby releasing the bearing.

[0018] Since multiple clamping components are arranged at intervals along the circumference of the rotating disk, when the clamping components hold the bearing, they will apply a uniform clamping force to the bearing in the circumferential direction, so that the bearing is subjected to balanced force in the circumferential direction and improves the positioning accuracy of the bearing.

[0037] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0038] This disclosure provides a positioning device, such as... Figure 1 As shown, the positioning device includes a support platform 1 and a clamping assembly 2.

[0039] Figure 2 yes Figure 1 An exploded view of the clamping component, combined with... Figure 2 The clamping assembly 2 includes a rotating disk 21, a plurality of clamping members 22, and a plurality of connecting members 23 arranged corresponding to each of the clamping members 22. The rotating disk 21 is rotatably located on one side of the support platform 1. The plurality of clamping members 22 are arranged at intervals along the circumference of the rotating disk 21 and are all partially located in the support platform 1. Each of the plurality of clamping members 22 is capable of moving radially along the rotating disk 21.

[0040] Multiple connectors 23 and rotating disk 21 are movably located in the support platform 1, and each connector 23 is movably connected to the corresponding clamping member 22 and rotating disk 21 respectively. The connector 23 is used to drive the corresponding clamping member 22 to move when the rotating disk 21 rotates.

[0041] When the positioning device provided in the embodiments of this disclosure is used to clamp and position bearings, the support platform 1 can provide an installation base for the clamping assembly 2 and a platform for placing the bearings.

[0042] Since the clamping assembly 2 includes a rotating disk 21, multiple clamping elements 22, and multiple connecting elements 23 arranged one-to-one with the clamping elements 22, the rotating disk 21 can provide a mounting base for the clamping elements 22, and the connecting elements 23 can connect the clamping elements 22 to the rotating disk 21. Thus, when a bearing needs to be clamped, the bearing can be placed on the support platform 1, and then the rotating disk 21 can be rotated. After the rotating disk 21 rotates, the multiple clamping elements 22 can move radially inward along the rotating disk 21 under the action of the connecting elements 23, thereby clamping the bearing. Conversely, when the bearing needs to be released, the rotating disk 21 is controlled to rotate in the opposite direction. After the rotating disk 21 rotates in the opposite direction, the multiple clamping elements 22 can move radially outward along the rotating disk 21 under the action of the connecting elements 23, thereby releasing the bearing.

[0043] Since multiple clamping members 22 are arranged at intervals along the circumference of the rotating disk 21, when the clamping members 22 clamp the bearing, they will apply a clamping force to the bearing in the circumferential direction, so that the bearing is subjected to balanced force in the circumferential direction and improves the positioning accuracy of the bearing.

[0044] See also Figure 2 The rotating disk 21 includes a disk body 211 and a plurality of first rotating shafts 212, which are arranged in a one-to-one correspondence with a plurality of connecting members 23. The plurality of first rotating shafts 212 are distributed at intervals along the circumference of the disk body 211 and are all connected to the same disk surface of the disk body 211.

[0045] The connector 23 includes a rotating plate 231 and a second rotating shaft 232. The rotating plate 231 is a long strip-shaped structure, and its length direction is radial to that of the rotating disk 21. One end of the rotating plate 231 is movably fitted onto the first rotating shaft 212 corresponding to the rotating plate 231. The second rotating shaft 232 is located outside the disk body 211 and at the end of the rotating plate 231 away from the first rotating shaft 212. The second rotating shaft 232 is connected to the rotating plate 231 and is movably inserted into the clamping member 22 corresponding to the connector 23.

[0046] In the above implementation, the disc body 211 is capable of rotating about its own axis. The first rotating shaft 212 is used to enable the connecting member 23 to rotate relative to the disc body 211. The second rotating shaft 232 is used to enable the clamping member 22 to rotate relative to the rotating plate 231.

[0047] When the disc 211 rotates, it drives the first rotating shaft 212 to rotate synchronously around the axis of the disc 211. After the first rotating shaft 212 rotates, it will drive one side of the rotating plate 231 to move radially inward toward the disc 211. After the rotating plate 231 moves, it will drive the second rotating shaft 232 to move. The movement of the second rotating shaft 232 will drive the clamping member 22 to move radially inward toward the disc 211, thereby causing the clamping member 22 to grip the bearing.

[0048] In other examples, the clamping member 22 can also be connected to the rotating disk 21 via a connector 23 of other structures, such as a rotating disk with an internal gear ring on its inner wall. The connector 23 consists of multiple pinions that mesh with the internal gear ring of the rotating disk. The clamping member 22 has a rack arranged radially to mesh with the pinions. In this way, when the rotating disk rotates, the pinions rotate accordingly, and the pinions drive the rack to move radially along the rotating disk, thereby achieving radial movement of the clamping member 22. However, this structure is not very convenient to arrange.

[0049] Figure 3 for Figure 1 The structural diagram of the support platform in the diagram, combined with Figure 3 Optionally, the support platform 1 is provided with a sliding groove 10 corresponding to a plurality of clamping members 22, and the length direction of the sliding groove 10 is the radial direction of the disc body 211.

[0050] See also Figure 2 The clamping member 22 includes a clamping block 221 and a slider 222. The clamping block 221 is located on the side of the slider 222 away from the rotating plate 231 along the axial direction of the rotating disk 21, and the clamping block 221 is connected to the slider 222. Part of the structure of the slider 222 is movably located in the corresponding groove 10 of the clamping member 22 and fits against the groove wall of the corresponding groove 10.

[0051] In the above implementation, the clamping block 221 is used to clamp the bearing. The slider 222 is used to cooperate with the slide groove 10 to limit the movement of the clamping block 221, so that the clamping block 221 can only move radially along the rotating disk 21.

[0052] For ease of arrangement, the slider 222 is an I-shaped block, with its middle portion confined within the groove 10. Furthermore, the slider 222 is welded to the clamping block 221 and the rotating plate 231 on both sides along the axis of the rotating disk 21.

[0053] See also Figure 2 Optionally, the clamping member 22 further includes a pressing plate 223 and a plurality of first elastic members 224. The pressing plate 223 is located on one side of the clamping block 221 in a radially inward direction along the rotating disk 21. The plurality of first elastic members 224 are spaced apart between the pressing plate 223 and the clamping block 221, and the two ends of each of the plurality of first elastic members 224 are respectively connected to the pressing plate 223 and the clamping block 221. The extension and retraction direction of the first elastic member 224 is its own length direction and is radial to the rotating disk 21.

[0054] In the above implementation, the extrusion plate 223 is used to contact the bearing. The first elastic member 224 is used to flexibly connect the extrusion plate 223 and the clamping block 221 together. In this way, when clamping the bearing, the elastic force of the first elastic member 224 can make the extrusion plate 223 slowly contact the bearing, preventing the extrusion plate 223 from being damaged by excessive force. At the same time, when multiple clamping members 22 clamp the bearing simultaneously, the different extension and retraction amounts of the first elastic member 224 can ensure that each extrusion plate 223 can fit against the outer wall of the bearing, improving the positioning effect.

[0055] For example, a rubber pad is provided on the side of the extrusion plate 223 away from the clamping block 221. The rubber pad can increase the friction between the extrusion plate 223 and the bearing, and at the same time prevent the extrusion plate 223 from making hard contact with the bearing, thereby avoiding damage to the bearing by the extrusion plate 223 and affecting the subsequent use of the bearing.

[0056] Figure 4 for Figure 2 A schematic diagram of the structure of the clamping component, combined with Figure 4 Optionally, the clamping block 221 has a plurality of spaced guide holes 2210 extending radially along the rotating disk 21. The clamping member 22 also includes a plurality of guide rods 225 arranged one-to-one with a plurality of first elastic members 224. The plurality of guide rods 225 correspond one-to-one with a plurality of guide holes 2210. Each of the plurality of guide rods 225 is located within a corresponding first elastic member 224, and one end of the guide rod 225 is movably located within a corresponding guide hole 2210, while the other end is connected to the pressing plate 223.

[0057] In the above implementation, by setting the guide rod 225, the first elastic element 224 will not bend when it contracts, thereby avoiding the bending of the first elastic element 224 from affecting the rebound effect. The guide hole 2210 is used to realize the movable connection between the guide rod 225 and the clamping block 221, and also to limit the guide rod 225.

[0058] Figure 5 for Figure 4 Enlarged view of point A in the middle, combined with Figure 5 Optionally, the guide hole 2210 has at least one first limiting groove 2211 in its wall, the first limiting groove 2211 communicating with the guide hole 2210 and extending along the axial direction of the guide hole 2210. The outer wall of the guide rod 225 is provided with at least one first limiting block 226, the first limiting block 226 being connected to the guide rod 225 and corresponding one-to-one with the first limiting groove 2211, the first limiting block 226 being located within the corresponding first limiting groove 2211.

[0059] In the above implementation, the cooperation between the first limiting groove 2211 and the first limiting block 226 can further limit the movement of the guide rod 225, so that the guide rod 225 can only move radially along the rotating disk 21.

[0060] In this embodiment of the present disclosure, in order to improve the limiting effect, there are two first limiting grooves 2211 and two first limiting blocks 226, with the two first limiting blocks 226 located on opposite sides of the same diameter of the guide rod 225. The two first limiting blocks 226 correspond one-to-one with the two first limiting grooves 2211.

[0061] The first elastic element 224 is a telescopic spring. To simplify the structure, there are four clamping elements 22, which are evenly distributed along the circumference of the rotating disk 21.

[0062] See you again Figure 1 Optionally, a nut is embedded in the support platform 1. The positioning device also includes a lateral adjustment assembly 3, which includes a frame 31, a lateral drive component 32, and a lateral adjustment rod 33. The frame 31 is fitted over the support platform 1. The lateral drive component 32 is located outside the frame 31 and connected to it. One end of the lateral adjustment rod 33 is connected to the lateral drive component 32, and the other end of the lateral adjustment rod 33 is located inside the frame 31 and threadedly connected to the nut of the support platform 1. The length direction of the lateral adjustment rod 33 is perpendicular to the axial direction of the rotating disk 21.

[0063] In the above implementation, the lateral adjustment component 3 can control the horizontal movement of the support platform 1, thereby adjusting the support platform 1 to move along the length direction of the lateral adjustment rod 33, so that the bearing on the support platform 1 can be positioned according to actual needs.

[0064] In actual use, the transverse adjustment rod 33 is controlled to rotate around its own axis by the transverse drive 32. After the transverse adjustment rod 33 rotates, the support platform 1, which is threadedly connected to the transverse adjustment rod 33, can move along the length direction of the transverse adjustment rod 33, thereby causing the support platform 1 to move.

[0065] In this embodiment, the lateral drive component 32 is a motor, and its output end is connected to the end of the lateral adjusting rod 33 via a coupling. The lateral adjusting rod 33 is a threaded rod with a threaded outer wall. The nut inside the support platform 1 has an internal thread that matches the thread of the lateral adjusting rod 33.

[0066] See also Figure 1 Optionally, the frame 31 has through grooves 310 in the opposite side walls, and the length direction of the through grooves 310 is the same as the length direction of the transverse adjusting rod 33.

[0067] The support platform 1 has limiting protrusions 11 on opposite sides. The limiting protrusions 11 correspond one-to-one with the through grooves 310, and the limiting protrusions 11 are movably located in the corresponding through grooves 310. The limiting protrusions 11 are in contact with the groove wall of the corresponding through groove 310.

[0068] In the above implementation, the cooperation between the through groove 310 and the limiting protrusion 11 can limit the movement of the support platform 1, so that the support platform 1 can only move along the length direction of the horizontal adjusting rod 33 under the control of the horizontal adjusting component 3, thereby improving the positioning effect of the bearing.

[0069] Figure 6 This is a schematic diagram of another positioning device provided in an embodiment of the present disclosure, combined with... Figure 6 The positioning device also includes a longitudinal adjustment component 4.

[0070] Figure 7 for Figure 6 The structural diagram of the support platform and clamping components is not shown in the image. Figure 7 The longitudinal adjustment component 4 includes a base 41, a longitudinal drive component 42, a longitudinal adjustment rod 43, and an adjustment block 44. The base 41 is located on one side of the frame 31.

[0071] The longitudinal drive member 42 is located on and connected to the base 41. One end of the longitudinal adjusting rod 43 is connected to the longitudinal drive member 42, and the other end of the longitudinal adjusting rod 43 is rotatably located inside the base 41. The longitudinal drive member 42 is used to drive the longitudinal adjusting rod 43 to rotate around its own axis. The length direction of the longitudinal adjusting rod 43 is perpendicular to the length direction of the transverse adjusting rod 33. The adjusting block 44 is sleeved on the longitudinal adjusting rod 43 and is threadedly connected to the longitudinal adjusting rod 43. The adjusting block 44 is connected to the frame 31.

[0072] In the above implementation, the base 41 provides a mounting foundation for the frame 31, the longitudinal drive member 42, the longitudinal adjusting rod 43, and the adjusting block 44. The longitudinal drive member 42 drives the longitudinal adjusting rod 43 to rotate. The adjusting block 44 is threadedly engaged with the longitudinal adjusting rod 43 so that after the longitudinal adjusting rod 43 rotates, the adjusting block 44 can move along the length direction of the longitudinal adjusting rod 43, thereby causing the frame 31 to move. After the frame 31 moves, it can move the support platform 1 inside the frame 31 together.

[0073] Optionally, the base 41 has at least one trapezoidal guide groove 410 on the surface facing the frame 31, and the extension direction of the guide groove 410 is the same as the length direction of the longitudinal adjusting rod 43.

[0074] The frame 31 has at least one trapezoidal guide block 311 on the side facing the base 41. The guide block 311 corresponds one-to-one with the guide groove 410, and the guide block 311 is movably located in the guide groove 410 and fits against the groove wall of the guide groove 410.

[0075] In the above implementation, the movement of the frame 31 can be limited by the cooperation of the guide block 311 and the guide groove 410, so that the frame 31 and the support platform 1 can only move along the length direction of the longitudinal adjustment rod 43.

[0076] In this embodiment of the present disclosure, in order to improve the limiting effect, there are two guide blocks 311 and two guide grooves 410 corresponding one-to-one with the two guide blocks 311. The two guide grooves 410 are arranged at intervals along the length direction of the transverse adjustment rod 33.

[0077] Optionally, the positioning device further includes a protective assembly 5, which includes a bracket 51, a protective cover 52, and a protective drive member 53. The bracket 51 is located outside the base 41 and is connected to the base 41. The protective cover 52 is located between the bracket 51 and the support platform 1 along the axial direction of the rotating disk 21, and is movably connected to the bracket 51. The protective drive member 53 is located on the side of the bracket 51 away from the support platform 1 and is connected to the bracket 51. The protective drive member 53 is connected to the protective cover 52 and is used to drive the protective cover 52 to move along the axial direction of the rotating disk 21, so that the protective cover 52 closes the clamping assembly 2 after the bearing is clamped in the clamping assembly 2.

[0078] In the above implementation, the protective component 5 is used to cover the clamping component 2, preventing the shaft from popping out due to pressure when the bearing is positioned and pressed together with the shaft, thus improving the safety of the device. The bracket 51 provides a mounting base for the protective cover 52 and the protective drive component 53. The protective cover 52 covers the clamping component 2. The protective drive component 53 drives the protective cover 52 to move, allowing it to move towards or away from the clamping component 2.

[0079] In this embodiment, the protective drive component 53 is a cylinder. The output end of the cylinder is connected to the pressure cover 521. The length direction of the piston rod of the cylinder is the axial direction of the rotating disk 21. By extending and retracting the piston rod of the cylinder, the pressure cover 521 can be controlled to move the protective frame 522 toward or away from the support platform 1.

[0080] Figure 8 for Figure 6 A structural diagram of the protective shield, combined with Figure 8 Optionally, the protective cover 52 includes a pressure cap 521, a protective frame 522, and a plurality of second elastic members 523. The pressure cap 521 is movably inserted into the protective frame 522 and, together with the protective frame 522, defines a protective space 520 for accommodating the clamping assembly 2. A pressing module for pressing the bearing is provided on the side of the pressure cap 521 facing the protective space 520.

[0081] Multiple second elastic elements 523 are spaced apart between the pressure cap 521 and the protective frame 522. The two ends of the second elastic elements 523 are connected to the pressure cap 521 and the protective frame 522 respectively. The extension and retraction direction of the second elastic elements 523 is the axial direction of the rotating disk 21.

[0082] The pressing module is equipped with a rotating shaft. During pressing, the rotating shaft can be pressed into the inner hole of the bearing by moving the pressure cover 521 toward the support platform 1.

[0083] In the above implementation, the protective cover 52 is configured as described above, and the pressure cover 521 and the protective frame 522 can be flexibly connected together by the second elastic element 523.

[0084] In this way, once the bearing is positioned by the clamping assembly 2, the pressure cap 521 can be controlled to move downwards. After the pressure cap 521 moves downwards, the second elastic element 523 can drive the protective frame 522 to move downwards, so that the protective frame 522 covers the positioning area of ​​the bearing. Then, the pressure cap 521 continues to move downwards, causing the protective frame 522 to press against the second elastic element 523, causing the second elastic element 523 to generate a rebound force. By setting the second elastic element 523, the second elastic element 523 drives the protective frame 522 to fit tightly against the pressing area, thereby improving the protection.

[0085] The bearing and shaft are pressed together by the pressing module inside the pressure cover 521. At the same time, the pressure cover 521 and the protective frame 522 can seal the positioning area, so as to prevent the shaft from popping out due to pressure during positioning and pressing, thus improving the safety of the device.

[0086] Optionally, the pressure cap 521 has a U-shaped structure, with an opening facing the protective frame 522. The opposite side walls of the pressure cap 521 that define the opening each have a built-in groove 5210, and the extension direction of the built-in groove 5210 is the axial direction of the rotating disk 21.

[0087] The multiple second elastic elements 523 are divided into two groups of second elastic elements. Each group of second elastic elements includes multiple second elastic elements 523. The two groups of second elastic elements correspond one-to-one with the opposite side walls of the protective frame 522 and the built-in groove 5210. All the second elastic elements 523 in each group of second elastic elements and the side walls of the protective frame 522 connected to the group of second elastic elements are located in the corresponding built-in groove 5210.

[0088] In the above implementation, the built-in groove 5210 is used to provide accommodating space for the second elastic member 523 and the side wall of the protective frame 522, so that the pressure cover 521 and the protective frame 522 can move relative to each other.

[0089] Optionally, each of the opposite side walls of the protective frame 522 has a plurality of spaced-apart holes 5220, the axis of which is axially oriented with respect to the axis of the rotating disk 21.

[0090] The protective cover 52 also includes multiple insert rods 524, which correspond one-to-one with multiple second elastic elements 523 and multiple insertion holes 5220. One end of the insert rod 524 is connected to the bottom of the built-in groove 5210, and the other end of the insert rod 524 is movably located in the corresponding insertion hole 5220, and the middle part of the insert rod 524 is inserted into the corresponding second elastic element 523.

[0091] In the above implementation, the insertion hole 5220 is used to provide movement space for the insertion rod 524. The arrangement of the insertion rod 524 can prevent bending when the second elastic member 523 retracts, so that the relative movement between the pressure cap 521 and the protective frame 522 can only be along the axial direction of the insertion rod 524.

[0092] Figure 9 for Figure 8 Enlarged view at point B, combined with Figure 9 Optionally, the wall of the socket 5220 has at least one second limiting groove 5221, which communicates with the socket and extends along the axial direction of the socket 5220.

[0093] The outer wall of the insertion rod 524 is provided with at least one second limiting block 525. The second limiting block 525 is connected to the insertion rod 524 and corresponds one-to-one with the second limiting groove 5221. The second limiting block 525 is located in the corresponding second limiting groove 5221.

[0094] In the above implementation, the cooperation between the second limiting groove 5221 and the second limiting block 525 can further limit the movement of the insertion rod 524, so that the insertion rod 524 can only extend along the axial direction of the insertion hole 5220.

[0095] In this embodiment of the disclosure, in order to improve the limiting effect, there are two second limiting blocks 525 and two second limiting grooves 5221 that correspond one-to-one with the two second limiting blocks 525. The two second limiting grooves 5221 are arranged opposite each other along the same diameter of the insertion hole 5220.

[0096] See you again Figure 6 or Figure 7 Optionally, the bracket 51 includes a middle connecting plate 511, two vertical plates 512, and two limiting rods 513. The two vertical plates 512 are parallel to each other, and one end of the length direction of each vertical plate 512 is connected to one end of the length direction of the middle connecting plate 511, while the other end of the length direction of the vertical plate 512 is connected to the base 41. The middle connecting plate 511 is connected to the protective drive component 53.

[0097] Two limiting rods 513 correspond one-to-one with two vertical plates 512, and each limiting rod 513 is located in the side wall of the corresponding vertical plate 512. The length direction of the limiting rod 513 is the axial direction of the rotating disk 21. The protective cover 52 also includes two connecting rods 526. The two connecting rods 526 are coaxial and located on opposite sides of the pressure cover 521. The two connecting rods 526 correspond one-to-one with the two limiting rods 513. One end of each connecting rod 526 is movably sleeved on the corresponding limiting rod 513, and the other end of the connecting rod 526 is connected to the pressure cover 521. The connecting rod 526 is perpendicular to the limiting rod 513.

[0098] In the above implementation, the bracket 51 is configured with the above structure, and can be connected to the base 41 via two vertical plates 512, so that the bracket 51 is fixedly installed on the base 41. At the same time, the two vertical plates 512 are connected by an intermediate connecting plate 511, and the intermediate connecting plate 511 provides an installation base for the protective drive component 53, etc.

[0099] Two limiting rods 513 are used to cooperate with two connecting rods 526 so that the protective cover 52 can be slidably connected to the bracket 51. At the same time, the limiting rods 513 limit the movement of the protective cover 52, so that the protective cover 52 can only move along the length direction of the limiting rods 513 under the drive of the protective drive member 53.

[0100] See also Figure 6 or Figure 7Optionally, the positioning device further includes a support assembly 6, which is located on the side of the base 41 away from the lateral adjustment assembly 3. The support assembly 6 includes a plurality of support feet 61, which are spaced apart, and one end of each support foot 61 is connected to the base 41 along the axial direction of the rotating disk 21, and one end of each support foot 61 can move relative to its other end along the axial direction of the rotating disk 21.

[0101] In the above implementation, by setting multiple support feet 61 at the bottom of the base 41, the support height of the support platform 1 can be adjusted by changing the length of the support feet 61. Thus, with the above structure, the support height of the support feet 61 can be flexibly adjusted, thereby avoiding the tilted support platform 1 from affecting the positioning and pressing accuracy of the bearing.

[0102] Figure 10 for Figure 6 A structural diagram of one of the supporting legs, combined with Figure 10 Optionally, the support foot 61 includes a support rod 611 and a support sleeve 612. One end of the support rod 611 is connected to the base 41, and the other end of the support rod 611 is movably located in the support sleeve 612 and is threadedly connected to the support rod 611 and the support sleeve 612.

[0103] In the above implementation, the support foot 61 is configured with the above structure, which allows for flexible adjustment of the support height of the support foot 61 and avoids the tilted support platform 1 from affecting the positioning and pressing accuracy of the bearing.

[0104] For example, by controlling the rotation of the support sleeve 612, the support sleeve 612 can move along the outer wall of the support rod 611 via the thread. The distance between the two ends of the support sleeve 612 and the support rod 611 that are far apart from each other can be changed, thereby allowing the distance between the support platform 1 and the ground to be adjusted, so as to avoid the tilted support platform 1 from affecting the positioning and pressing accuracy of the bearing.

[0105] In other examples, the support foot 61 can also be other structures, such as a telescopic rod, a hydraulic cylinder, etc.

[0106] Optionally, the support foot 61 also includes a movable ball 613 and a support plate 614. The movable ball 613 is connected to the end of the support sleeve 612 away from the support rod 611. The support plate 614 has a hinge hole in the middle, and the movable ball 613 is movably located in the hinge hole, and the movable ball 613 can swing relative to the support plate 614.

[0107] In the above implementation, by setting the movable ball 613, the bottom of the support sleeve 612 and the support plate 614 can be connected by a ball joint. The support sleeve 612 can rotate in any direction relative to the support plate 614, thereby allowing the support plate 614 to be laid flat on uneven ground. That is, the support foot 61 can be used on uneven ground.

[0108] For example, the support plate 614 has anti-slip rubber on the side away from the movable ball 613. This increases the friction between the support foot 61 and the ground, preventing the support foot 61 from shifting.

[0109] Optionally, the support foot 61 also includes a lever 615, the middle part of which is connected to the support sleeve 612, and the length direction of the lever 615 is perpendicular to the axial direction of the support sleeve 612.

[0110] In the above implementation, the lever 615 is designed for easy manual rotation of the support sleeve 612. That is, by moving the lever 615, the rotation of the support sleeve 612 can be controlled, thereby adjusting the support height of the support foot 61. This prevents the tilted support platform 1 from affecting the positioning and pressing accuracy of the bearing.

[0111] See you again Figure 6 or Figure 7 Optionally, the support assembly 6 also includes a plurality of casters 62, which are spaced apart and rotatably connected to the base 41. The rotation axis of each caster 62 is perpendicular to the rotation axis of the rotating disk 21.

[0112] In the above implementation, the caster 62 allows the base 41 to make rotational contact with the ground, thereby reducing the friction between the base 41 and the ground. This eliminates the need for additional mechanical equipment when moving the positioning device, making it convenient to move or relocate the positioning device.

[0113] In this embodiment of the disclosure, there are four casters 62, which are located at the four corners of the base 41.

[0114] The following is a brief introduction to the usage process of the positioning device provided in the embodiments of this disclosure:

[0115] After moving the positioning device to the desired position, level it by adjusting the support foot 61. Then, place the bearing on the support platform 1, and drive the disk body 211 to rotate via the rotation drive 213. After the disk body 211 rotates, it drives one side of the rotating plate 231 to rotate inward via the first rotating shaft 212. The other side of the rotating plate 231 drives the clamping block slider 222 to move radially inward toward the disk body 211, thereby moving the clamping block 221 inward. The clamping block 221 drives the first elastic element 224 and the pressing plate 223 to move. When the pressing plate 223 contacts the outer wall of the bearing, the contraction of the first elastic element 224 allows each pressing plate 223 to fit against the outer wall of the bearing, thereby effectively fixing the bearing and preventing it from moving.

[0116] Then, the frame 31 is moved longitudinally by adjusting the longitudinal adjustment component 4, and the support platform 1 is moved laterally by adjusting the lateral adjustment component 3, until the bearing is aligned with the rotating shaft that needs to be pressed together.

[0117] Finally, the protective drive component 53 drives the pressure cover 521 to move, and the pressure cover 521 drives the protective frame 522 to move, so that the protective frame 522 and the pressure cover 521 seal the pressing area of ​​the rotating shaft and the bearing, so as to avoid accidental damage to the surrounding area during positioning and pressing.

[0118] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
