Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of machining, in particular to a wheel operation device. BACKGROUND

[0002] In the production and manufacturing process of the wheel, the appearance machining is the key process of the wheel appearance forming. Generally, after the wheel appearance surface is finished, burrs exist in the tool exit of the appearance machining position, which affects the appearance of the wheel and reduces the coating adhesion rate of the subsequent wheel coating link, resulting in the increase of the unqualified rate of the wheel. Therefore, in order to ensure the quality of the wheel product, the overall appearance of the wheel needs to be checked manually, and the burrs are removed manually.

[0003] For this, the related art usually adopts the corresponding workbench to assist in wheel deburring / inspection. Specifically, the workbench includes a table body arranged on the ground and a roller arranged on the table body. When operating, the wheel rim contacts the roller to rotate the wheel, which is used for deburring and inspection of the wheel machining surface (such as the wheel appearance surface finished). However, for the wheel that has completed the preliminary coating, such as the wheel that has been coated with color paint before finishing, when the wheel is placed on the roller of the workbench for deburring / inspection, the wheel rotates by contacting the roller with the rim, and part of the rim will be off the paint due to friction with the roller, resulting in unqualified products. Moreover, since the height of the workbench is generally fixed, when the operator performs deburring / inspection on the side surface of the wheel placed on the roller, the operator needs to work for a long time with his head sideways and bent over, or needs to manually turn over the wheel, which increases the operation difficulty of the operator and reduces the operation efficiency of the operator.

[0029] In combination Figure 1 , Figure 6 The utility model embodiment provides a kind of wheel working device, including base 1, telescopic support mechanism 2 and wheel supporting mechanism 3, telescopic support mechanism 2 is rod-like structure;Base 1 is used to be installed on installation plane, one end of telescopic support mechanism 2 is connected with base 1, the other end is connected with wheel supporting mechanism 3;The included angle of the axis of wheel supporting mechanism 3 and installation plane is set as angle, and wheel supporting mechanism 3 is used to be inserted into the center hole of the hub 61 of the wheel to be operated 6 and support the wheel to be operated 6.

[0030] In the embodiment, the wheel working device is used to assist operator to carry out deburring, inspection and other operations (or operations) to the wheel to be operated 6 (which includes hub 61, spoke 62 and rim 63 connected in sequence, as shown in Figure 6 ), which includes base 1, telescopic support mechanism 2 and wheel supporting mechanism 3, wheel supporting mechanism 3 is used to support the wheel to be operated 6, and the operation of operator is facilitated, and wheel supporting mechanism 3 has support surface, and the axis of wheel supporting mechanism 3 is perpendicular to its support surface;Telescopic support mechanism 2 is used to support wheel supporting mechanism 3, to realize the height adjustment of wheel supporting mechanism 3 while ensuring to provide stable support, and to improve the comfort of operator when operating;Base 1 is used to be installed on installation plane (such as ground or other plane for installing wheel working device, usually horizontal plane), to realize the installation of wheel working device on installation plane, and to ensure the stability of wheel working device when used for wheel operation.

[0031] Specifically, the wheel supporting mechanism 3 is used for inserting into the center hole of the hub 61 of the to-be-operated wheel 6 and supporting the to-be-operated wheel 6, such as the wheel supporting mechanism 3 extending into the area surrounded by the rim 63 of the to-be-operated wheel 6 from the opposite side of the appearance surface of the to-be-operated wheel 6, and inserting into the center hole of the hub 61 of the to-be-operated wheel 6 through the area, and supporting the end surface of the hub 61 of the to-be-operated wheel 6 facing the end of the wheel supporting mechanism 3 by the supporting surface of the wheel supporting mechanism 3, so as to realize the stable supporting of the wheel supporting mechanism 3 to the wheel from the opposite side of the appearance surface of the wheel, thereby supporting the hub 61 of the to-be-operated wheel 6 by the wheel supporting mechanism 3 while ensuring that the wheel supporting mechanism 3 does not contact the appearance surface of the wheel, preventing the wheel from deviating or shaking during operation, effectively ensuring that the wheel remains stable during operation, thereby improving the efficiency of the operator in deburring and inspection operation, and avoiding the paint falling off the appearance surface of the to-be-operated wheel 6 during the deburring and inspection operation of the wheel. And the axis of the wheel supporting mechanism 3 is arranged at an angle with the installation plane (i.e. the horizontal plane), such as an acute angle or an obtuse angle, so that the rim 63 (or the appearance surface) of the to-be-operated wheel 6 forms a certain inclination angle with the horizontal plane after being installed on the wheel supporting mechanism 3, which can make the operator have a more comfortable working angle and operation space when deburring or inspecting, reduce the fatigue and strain of the operator caused by long-time side head, thereby significantly improving the operation efficiency and experience; at the same time, this inclined design also facilitates the rotation of the wheel or the movement of the operator around the wheel operation device, so that each part of the to-be-operated wheel 6 can be easily adjusted to the line of sight range and the best working angle of the operator, effectively improving the accuracy and efficiency of the operation, and realizing the full deburring or inspection operation of the operator to different areas or positions of the wheel, avoiding the dead angle, omission or manual turning of the wheel caused by fixed angle or fixed operation position, further reducing the labor intensity of the operator and improving the operation efficiency.

[0032] The telescopic supporting mechanism 2 can realize the height adjustment of the wheel supporting mechanism 3 through telescopic expansion, so as to flexibly adjust the overall height of the wheel working device according to the actual needs of the operator, such as adjusting the wheel supporting mechanism 3 used for supporting the to-be-worked wheel 6 to the working height required by the operator, avoiding the uncomfortable working posture of the operator needing to keep bending and tilting head for a long time due to the unsuitable working height, thereby reducing the labor intensity of the operator and improving the working comfort; in addition, reasonable height adjustment can also effectively improve the precision and efficiency of the work, especially in the process of fine operation such as wheel detail inspection and burr cleaning, the operator can complete the operation at the best viewing angle and the most convenient working position. Moreover, the telescopic supporting mechanism 2 is in a rod-shaped structure and is arranged on the base 1 mounted on the mounting plane, so as to ensure the stable support of the wheel supporting mechanism 3 while reducing the space required by the telescopic supporting mechanism 2. In this way, compared with the workbench adopting a cubic table body in the related art, on the one hand, the overall space required by the wheel working device is reduced, the utilization rate of the working site is improved, and the operator can move flexibly in the working area and move flexibly around the wheel working device, thereby improving the flexibility and efficiency of the work; on the other hand, the telescopic supporting mechanism 2 in a rod-shaped structure can reduce the overall weight of the wheel working device through simplified design while maintaining sufficient supporting strength, which is convenient for carrying and adjusting the position of the wheel working device, thereby enhancing the practicability of the wheel working device and reducing the production and installation cost of the wheel working device.

[0033] In summary, the wheel operation device of the embodiment is used to assist the operator to deburr and check the to-be-operated wheel 6, so as to improve the efficiency and flexibility of the wheel deburring and checking operation, and avoid the paint falling off the appearance surface of the wheel during the wheel deburring and checking operation. Specifically, the wheel operation device is arranged on the base 1 installed on the installation plane through the telescopic supporting mechanism 2 in a rod-shaped structure, so as to reduce the space required by the wheel operation device as a whole while ensuring stable support of the wheel supporting mechanism 3, improve the utilization rate of the operation site, facilitate the flexible movement of the operator in the operation area, and facilitate the flexible movement of the operator around the wheel operation device, improve the flexibility and efficiency of the operation, reduce the overall weight of the wheel operation device, facilitate the carrying and position adjustment of the wheel operation device, thereby enhancing the practicability of the wheel operation device, and reducing the production and installation cost of the wheel operation device. The wheel supporting mechanism 3 is used to insert the center hole of the hub 61 of the to-be-operated wheel 6 in the rim 63 of the to-be-operated wheel 6 (i.e. in the area surrounded by the rim 63) and support the to-be-operated wheel 6, so as to stably support the wheel from the opposite surface of the appearance surface of the wheel, thereby ensuring that the wheel remains stable during the operation while ensuring that the wheel supporting mechanism 3 does not contact the appearance surface of the wheel; and the axis of the wheel supporting mechanism 3 is arranged at an angle with the installation plane, so that the operator has a more comfortable operation view and operation space when deburring or checking, thereby improving the operation efficiency and operation experience.

[0034] Optionally, in combination with Figures 1-3 As shown, the wheel supporting mechanism 3 includes a supporting structure 31 and a positioning structure 32 arranged coaxially, one end of the supporting structure 31 is connected with the telescopic supporting mechanism 2, and the positioning structure 32 is protruded at the other end of the supporting structure 31; and the positioning structure 32 is used to be arranged in the center hole of the hub 61, and the cross-sectional area of the supporting structure 31 is greater than that of the positioning structure 32.

[0035] In this embodiment, the wheel supporting mechanism 3 is used to support and position the to-be-worked wheel 6 from the inside of the to-be-worked wheel 6, so as to ensure that the to-be-worked wheel 6 remains stable during the working process. Specifically, the wheel supporting mechanism 3 comprises a supporting structure 31 and a positioning structure 32. The supporting structure 31 is arranged in the wheel rim 63 of the to-be-worked wheel 6 (i.e. in the area surrounded by the wheel rim 63) and supports the wheel hub 61. One end of the supporting structure 31 is connected to the end of the telescopic supporting mechanism 2 away from the base 1, and the positioning structure 32 is protruded from the other end of the supporting structure 31 (i.e. the end of the supporting structure 31 away from the telescopic supporting mechanism 2) so as to be arranged in the central hole of the wheel hub 61 of the to-be-worked wheel 6. Through cooperation with the central hole of the wheel hub 61, the positioning of the to-be-worked wheel 6 on the supporting structure 31 is realized, and the stability of the position of the to-be-worked wheel 6 on the wheel supporting mechanism 3 is ensured. In this way, while ensuring that the wheel supporting mechanism 3 does not contact the appearance surface of the to-be-worked wheel 6, the to-be-worked wheel 6 is supported by the supporting structure 31 and positioned by the positioning structure 32, so as to prevent the to-be-worked wheel 6 from deviating or shaking during the working process, effectively ensure that the to-be-worked wheel 6 remains stable during the working process, and thus improve the efficiency of the operator in deburring and inspection work and avoid the problem of paint falling during the deburring and inspection work of the to-be-worked wheel 6.

[0036] Moreover, the supporting structure 31 and the positioning structure 32 are coaxially arranged, which can ensure the accuracy and coordination of supporting and positioning the to-be-worked wheel 6. When the positioning structure 32 is arranged in the central hole of the wheel hub 61 of the to-be-worked wheel 6, the uniform contact of the supporting structure 31 with the wheel hub 61 of the to-be-worked wheel 6 is ensured, so as to ensure that the force acting on the supporting structure 31 is relatively uniform and avoid the problem of the to-be-worked wheel 6 deviating or shaking due to the local overloading of the supporting structure 31, thereby ensuring the stability and reliable support of the to-be-worked wheel 6 during the working process. The cross-sectional area of the supporting structure 31 (i.e. the area of the surface exposed when the supporting structure 31 is cut by a plane perpendicular to the axis of the supporting structure 31; and when the supporting structure 31 is a hollow structure, the cross-sectional area refers to the total area of the solid part and the hollow part in the cross section) is greater than the cross-sectional area of the positioning structure 32 (i.e. the area of the surface exposed when the positioning structure 32 is cut by a plane perpendicular to the axis of the positioning structure 32; and when the positioning structure 32 is a hollow structure, the cross-sectional area refers to the total area of the solid part and the hollow part in the cross section), so as to ensure that the supporting structure 31 does not enter the central hole of the wheel hub 61 of the to-be-worked wheel 6 when the positioning structure 32 enters the central hole of the wheel hub 61 of the to-be-worked wheel 6, but supports the wheel hub 61 of the to-be-worked wheel 6. That is, the supporting structure 31 is arranged in the wheel rim 63 of the to-be-worked wheel 6 and supports the wheel hub 61, and the supporting structure 31 with a relatively large cross-sectional area can more uniformly distribute the load, avoid the problem of deformation or instability of the to-be-worked wheel 6 due to local force concentration, and effectively improve the stability of the entire wheel working device during the working process of the to-be-worked wheel 6.

[0037] Optionally, the cross-sectional area of the support structure 31 is greater than the central hole area (or the cross-sectional area of the central hole) of the hub 61 of the wheel 6 to be worked on, so as to ensure that the support structure 31 can smoothly support the hub 61 of the wheel 6 to be worked on. The end surface area of the positioning structure 32 away from the support structure 31 is less than the central hole area of the hub 61 of the wheel 6 to be worked on, so as to ensure that the positioning structure 32 can be smoothly arranged in the central hole of the hub 61 of the wheel 6 to be worked on, and the positioning of the wheel 6 to be worked on on the support structure 31 is achieved. The specific size of the wheel supporting mechanism 3 is set according to actual needs. For example, for commonly used wheels, only the end surface area of the positioning structure 32 away from the support structure 31 is less than the smallest central hole area in the commonly used wheel specifications, the cross-sectional area of the support structure 31 is greater than the largest central hole area in the commonly used wheel specifications, and the cross-sectional area of the support structure 31 is less than or equal to the inner circle cross-sectional area of the wheel rim 63 in the commonly used wheel specifications, and the compatibility and applicability of the wheel supporting mechanism 3 and the wheel working device for various commonly used wheel specifications can be ensured.

[0038] Optionally, in combination with Figures 1-3 As shown in the figure, the positioning structure 32 is slidably connected to the support structure 31 along the axis.

[0039] In this embodiment, the positioning structure 32 is slidably connected to the support structure 31 in the axial direction of the wheel supporting mechanism 3, so that the positioning structure 32 is adapted to slide relative to the support structure 31 along the axial direction of the positioning structure 32. Thus, when the wheel supporting mechanism 3 is used to support the wheel 6 to be worked on, after the wheel 6 to be worked on is sleeved on the positioning structure 32 through the hub 61 central hole wall and abuts against (cooperates with) the positioning structure 32, the wheel 6 to be worked on presses the positioning structure 32 under the action of gravity, so that the wheel 6 to be worked on and the positioning structure 32 can move together relative to the support structure 31 along the axial direction of the positioning structure 32, until the hub 61 of the wheel 6 to be worked on is smoothly and stably supported on the support surface of the support structure 31 (i.e. the end surface of the support structure 31 away from the end of the positioning structure 32), achieving smooth and stable support of the wheel 6 to be worked on, and avoiding the situation that the hub 61 is damaged due to sliding friction between the hub 61 and the positioning structure 32. In addition, this embodiment can also make the positioning structure 32 applicable to various different size specifications of the hub 61 central hole, so that various different size specifications of the hub 61 central hole can be sleeved on the positioning structure 32 and can smoothly abut against the support surface of the support structure 31, thereby improving the applicability of the wheel supporting mechanism 3 and the wheel working device.

[0040] Optionally, in combination with Figures 1-3 , Figure 5 and Figure 6As shown, the support structure 31 comprises a supporting plate 311, a support cylinder 312 and a bottom plate 313 connected in sequence along the axial direction thereof, the bottom plate 313 being connected to the end of the telescopic support mechanism 2 away from the base 1; the positioning structure 32 comprises a connecting part 321 and a positioning part 322 arranged in sequence along the axial direction thereof, the connecting part 321 being located in the support cylinder 31 and being in sliding connection with the support cylinder 312, the positioning part 322 penetrating through the supporting plate 311, and the positioning part 322 being designed as a cone, the cross section of the positioning part 322 gradually decreasing in the direction away from the connecting part 321.

[0041] In this embodiment, the support structure 31 includes a support plate 311, a support cylinder 312 and a bottom plate 313 connected in sequence along the axial direction, which are connected in sequence to form a whole, providing stable support for the to-be-operated wheel 6. Among them, the support plate 311 is located at the top of the support structure 31 (i.e. at the end of the support structure 31 away from the base 1), used to support the hub 61 of the to-be-operated wheel 6, and the side of the support plate 311 away from the support cylinder 312 serves as the support surface of the wheel supporting mechanism 3, used to directly contact and support the hub 61 of the to-be-operated wheel 6; the bottom plate 313 is located at the bottom of the support structure 31 (i.e. at the end of the support structure 31 towards the base 1), used to connect with the telescopic support mechanism 2; the support cylinder 312 is arranged between the support plate 311 and the bottom plate 313, used to realize the connection of the support plate 311 and the bottom plate 313, and ensure the structural strength of the whole support structure 31. The positioning structure 32 includes a connecting part 321 and a positioning part 322 arranged in sequence along the axial direction, the connecting part 321 is located in the support cylinder 31 and is in sliding connection with the support cylinder 312, realizing the sliding connection of the positioning structure 32 and the support structure 31, and ensuring the stability of the connection of the positioning structure 32 and the support structure 31 while realizing the relative sliding of the positioning structure 32 and the support structure 31. The positioning part 322 is arranged through the support plate 311 away from the end connected with the connecting part 321, and the end of the positioning part 322 away from the support plate 311 has a certain distance to the support plate 311, realizing the protrusion of the positioning part 322 on the support plate 311 or the support structure 31, so as to be arranged through the center hole of the hub 61 of the to-be-operated wheel 6, providing a positioning reference for the support of the to-be-operated wheel 6. Moreover, the cross section (or cross sectional area) of the positioning part 322 gradually decreases along the direction away from the connecting part 321, such as the positioning part 322 is designed in the shape of a cone (such as a circular truncated cone or a circular cone), that is, the cross sectional area of the positioning part 322 gradually decreases in the direction of the bottom plate 313 pointing to the support plate 311. In this way, on the one hand, the positioning part 322 can be applied to the center hole of the hub 61 of various different sizes (i.e. the positioning part 322 can be smoothly arranged through the center hole of the hub 61 of various different sizes), improving the applicability of the wheel supporting mechanism 3 and the wheel operating device; on the other hand, when supporting the to-be-operated wheel 6, the side wall of the positioning part 322 (cooperating with the wall of the center hole of the hub 61 of the to-be-operated wheel 6) can play a guiding role, realizing the quick and accurate positioning of the to-be-operated wheel 6 on the wheel supporting mechanism 3, thereby ensuring the uniform contact of the support structure 31 and the hub 61 of the to-be-operated wheel 6, ensuring the relative uniformity of the stress of the support structure 31, avoiding the problem of deviation or shaking of the to-be-operated wheel 6 caused by the local overloading of the support structure 31, thereby ensuring the stability and support reliability of the to-be-operated wheel 6 during operation.

[0042] Exemplarily, as Figure 6As shown, if the cross-sectional area of the hub 61 central hole of the to-be-worked wheel 6 is greater than the minimum cross-sectional area of the positioning portion 322 and less than the maximum cross-sectional area of the positioning portion 322, when the wheel supporting mechanism 3 supports the to-be-worked wheel 6, the side surface of the positioning portion 322 is in contact with the wall of the hub 61 central hole of the to-be-worked wheel 6, and under the action of the gravity of the to-be-worked wheel 6, the to-be-worked wheel 6 and the positioning structure 32 can move together along the axis direction of the positioning structure 32 relative to the support structure 31, until the hub 61 of the to-be-worked wheel 6 is smoothly and stably supported on the support surface of the support structure 31 (i.e. the end surface of the support structure 31 at one end of the positioning structure 32), achieving smooth and stable support of the to-be-worked wheel 6, and avoiding the situation that the hub 61 is damaged due to sliding friction between the hub 61 and the positioning structure 32.

[0043] In summary, the wheel supporting mechanism 3 in the embodiment can be applied to to-be-worked wheels 6 of various sizes, achieving compatibility with to-be-worked wheels 6 of different sizes; and when supporting the to-be-worked wheel 6 through the positioning portion 322, the support plate 311 can smoothly and stably contact the hub 61 of the to-be-worked wheel 6, achieving smooth and stable support of the to-be-worked wheel 6, and avoiding or effectively reducing the situation that the hub 61 is damaged due to sliding friction between the hub 61 and the positioning structure 32. The sliding connection between the positioning structure 32 and the support structure 3 effectively avoids the situation that only some wheels can be used due to the fixed connection between the positioning structure 32 and the support structure 31 of the wheel supporting mechanism 3, for example, if the cross-sectional area of the hub 61 central hole of the to-be-worked wheel 6 is greater than the minimum cross-sectional area of the positioning portion 322 and less than the maximum cross-sectional area of the positioning portion 322, when the wheel supporting mechanism 3 supports the to-be-worked wheel 6, the hub 61 of the to-be-worked wheel 6 can only contact the positioning portion 322 and cannot contact the support plate 311, resulting in unstable support of the to-be-worked wheel 6.

[0044] Optionally, as shown in Figures 1-3 , Figure 5 and Figure 6 , the support structure 31 further comprises an elastic reset structure 315, which is located in the support cylinder 31 and is arranged between the connecting portion 321 and the bottom plate 313.

[0045] In this embodiment, the elastic reset structure 315 (e.g. a spring) of the support structure 31 is located in the support cylinder 312 and arranged between the connecting portion 321 and the bottom plate 313. The two ends of the elastic reset structure 315 abut against the connecting portion 321 and the bottom plate 313, respectively. When the positioning portion 322 moves along the axis of the support cylinder 312 towards the bottom plate 313 due to external force for operation requirement, the elastic reset structure 315 is compressed to store energy. When the external force is removed, the elastic reset structure 315 releases the stored energy and pushes the connecting portion 321 and the positioning portion 322 to reset to the initial position. In this embodiment, when the wheel supporting mechanism 3 does not support the wheel 6 to be operated, the connecting portion 321 and the supporting plate 311 abut against the side of the bottom plate 313 under the action of the elastic reset structure 315.

[0046] In this way, the arrangement of the elastic reset structure 315 enhances the flexibility and stability of the positioning structure 32, so that the positioning structure 32 can maintain good reset performance and operation accuracy in repeated use.

[0047] Optionally, in combination with Figures 1-3 As shown in the figure, the supporting plate 311 is provided with a receiving hole 311a, the diameter of the receiving hole 311a is smaller than the diameter of the connecting portion 321, and the positioning portion 322 passes through the supporting plate 311 through the receiving hole 311a.

[0048] In this embodiment, the support structure 31 is a hollow structure, the internal space of which is formed by the supporting plate 311, the support cylinder 312 (a cylindrical structure) and the bottom plate 313, and the supporting plate 311, the support cylinder 312 and the bottom plate 313 are coaxially arranged. The connecting portion 321 of the positioning structure 32 is arranged in the support cylinder 312, the supporting plate 311 is provided with a receiving hole 311a, the diameter of the receiving hole 311a is smaller than the diameter of the connecting portion 321, and the end of the positioning portion 322 of the positioning structure 32 away from the connecting portion 321 passes through the supporting plate 311 through the receiving hole 311a and extends out.

[0049] The accommodating hole 311a is coaxially arranged with the supporting cylinder 312 to ensure that the positioning part 322 extending out of the accommodating hole 311a is coaxially arranged with the supporting structure 31. The connecting part 321 is arranged in the supporting cylinder 312 and is in clearance fit with the supporting cylinder 312, facilitating the sliding connection of the connecting part 321 with the supporting cylinder 312, and the inner side wall of the supporting cylinder 312 guides the movement of the connecting part 321 along the axis direction of the supporting cylinder 312, thereby ensuring that the positioning structure 32 can move smoothly along the axis direction of the supporting cylinder 312. The diameter of the accommodating hole 311a is smaller than that of the connecting part 321, so as to ensure that the connecting part 321 cannot be pulled out of the accommodating hole 311a. In this way, the movement of the connecting part 321 along the axis direction of the supporting cylinder 312 is limited by the supporting plate 311, so as to avoid that the positioning structure 32 is separated from the supporting structure 31. The supporting cylinder 312, the bottom plate 313 and the supporting plate 311 are combined to limit the connecting part 321 in the space formed by the supporting plate 311, the supporting cylinder 312 and the bottom plate 313, thereby ensuring the stable sliding connection of the positioning structure 32 with the supporting structure 31.

[0050] Optionally, as shown in Figure 2 、 Figure 3 、 Figure 5 and Figure 6 , the supporting cylinder 312 comprises an outer cylinder 312a and an inner cylinder 312b arranged coaxially, and the inner cylinder 312b is arranged in the outer cylinder 312a. The connecting part 321 is arranged in the inner cylinder 312b and is in sliding fit with the inner cylinder 312b.

[0051] In the embodiment, the supporting structure 31 is in a hollow structure, and the internal space is formed by the supporting plate 311, the outer cylinder 312a of the supporting cylinder 312 and the bottom plate 313, and the supporting plate 311, the outer cylinder 312a and the bottom plate 313 are coaxially arranged. The inner cylinder 312b of the supporting cylinder 312 is arranged in the internal space formed by the supporting plate 311, the outer cylinder 312a and the bottom plate 313, and the inner cylinder 312b is coaxially arranged with the supporting cylinder 312. The two ends of the inner cylinder 312b are connected with the supporting plate 311 and the bottom plate 313 respectively, thereby improving the overall structural strength of the supporting structure 31. The supporting plate 311 is provided with an accommodating hole 311a for accommodating the positioning part 322, and the accommodating hole 311a is coaxially arranged with the inner cylinder 312b, so as to ensure that the positioning part 322 extending out of the accommodating hole 311a is coaxially arranged with the supporting structure 31. The connecting part 321 is arranged in the inner cylinder 312b and is in sliding fit (for example, in clearance fit) with the inner cylinder 312b. The inner side wall of the inner cylinder 312b guides the movement of the connecting part 321 along the axis direction of the inner cylinder 312b, thereby ensuring that the positioning structure 32 can move smoothly along the axis direction of the inner cylinder 312b.

[0052] In this way, by arranging the connecting portion 321 in the inner cylinder 312b and in sliding fit with the inner cylinder 312b, the positioning portion 322 can maintain good coaxiality during movement, ensuring that the positioning portion 322 precisely docks with the center hole of the hub 61 of the wheel 6 to be worked on, thereby avoiding the situation that the working efficiency is affected due to docking deviation.

[0053] Optionally, the elastic reset structure 315 (which can be an elastic member such as a spring) of the support structure 31 is arranged in the inner cylinder 312b and located between the connecting portion 321 and the bottom plate 313, so as to realize the limiting of the elastic reset structure 315 through the cooperation of the connecting portion 321, the bottom plate 313 and the inner cylinder 312b, thereby avoiding the situation that the elastic reset structure 315 is unstable or damaged due to excessive displacement or swing, and ensuring the stable driving of the connecting portion 321 by the elastic reset structure 315 during reset.

[0054] Optionally, one side of the bottom plate 313 towards the elastic reset structure 315 is provided with a first groove or a first boss for limiting one end of the elastic reset structure 315, and one side of the connecting portion 321 towards the elastic reset structure 315 is provided with a second groove or a second boss for limiting the other end of the elastic reset structure 315.

[0055] In this embodiment, in order to ensure the stability and accuracy of the elastic reset structure 315 during work, the bottom plate 313 and the connecting portion 321 for contacting the end of the elastic reset structure 315 are both provided with corresponding limiting structures. Specifically, one side of the bottom plate 313 towards the elastic reset structure 315 is provided with a groove structure (referred to as a first groove) for accommodating the end of the elastic reset structure 315 (such as a spring) or a boss structure (referred to as a first boss) for extending into the end of the elastic reset structure 315, and the end of the elastic reset structure 315 towards the bottom plate 313 is limited by the first groove (or the first boss); one side of the connecting portion 321 towards the elastic reset structure 315 is provided with a groove structure (referred to as a second groove) for accommodating the end of the elastic reset structure 315 or a boss structure (referred to as a second boss) for extending into the end of the elastic reset structure 315, and the end of the elastic reset structure 315 towards the bottom plate 313 is limited by the second groove (or the second boss). In this way, the end of the elastic reset structure 315 during work can be ensured to remain in position and form good contact with the connecting portion 321 and the bottom plate 313, thereby avoiding the situation that the elastic reset structure 315 is unstable or damaged due to excessive displacement or swing, and ensuring the stable driving of the connecting portion 321 by the elastic reset structure 315 during reset.

[0056] Optionally, the support plate 311 is made of a predetermined material, such as nylon material, polytetrafluoroethylene (PTFE) material or other high-molecular friction-reducing materials.

[0057] In this embodiment, the preset material is a material that can reduce or avoid damage to the hub 61 to be worked. By using such a material, the supporting plate 311 not only has high wear resistance and impact resistance, but also can effectively reduce the friction coefficient when the hub 61 to be worked contacts the supporting plate 311, thereby preventing the surface of the hub 61 from being scratched or damaged.

[0058] Optionally, the base 1 is provided with a mounting hole, and the base 1 and the mounting plane are detachably connected through fasteners at the mounting hole. This design can ensure the stability of the connection between the base 1 and the mounting plane while improving the convenience of installing and dismounting the wheel working device on the mounting plane.

[0059] Optionally, as shown in Figure 1 , Figure 2 and Figure 4 , the telescopic supporting mechanism 2 includes a connecting piece 23, a first rod piece 21, and a second rod piece 22. One end of the first rod piece 21 is connected with the base 1, one end of the second rod piece 22 is connected with the wheel supporting mechanism 3, and the other end of the first rod piece 21 is coaxially arranged with the other end of the second rod piece 22 and is inserted along the axial direction thereof. The first rod piece 21 is provided with a first positioning hole 211, the second rod piece 22 is provided with a second positioning hole 221, and the first rod piece 21 and the second rod piece 22 are connected through the connecting piece 23 at the first positioning hole 211 and the second positioning hole 221.

[0060] In this embodiment, the telescopic supporting mechanism 2 is used to adjust the height and supporting position of the wheel supporting mechanism 3 to adapt to different working scenes and requirements. The telescopic supporting mechanism 2 has a rod-shaped structure to reduce the space required by the telescopic supporting mechanism 2, improve the utilization rate of the working site, and improve the flexibility and efficiency of the operator's work and movement.

[0061] Specifically, the telescopic support mechanism 2 comprises a first rod 21 and a second rod 22, both in the form of a rod structure, and a connecting piece 23 for connecting the first rod 21 and the second rod 22. One end of the first rod 21 is fixedly connected to the base 1, ensuring the stability of the telescopic support mechanism 2 and the entire wheel working device; the second rod 22 is inserted and matched with the first rod 21 at the other end of the first rod 21, for example, the first rod 21 can be provided with an axial hole 212 extending along the axial direction of the first rod 21 at the end away from the base 1, i.e. the axial hole 212 extends from the end face of the end of the first rod 21 away from the base 1 along the axial direction of the first rod 21 towards the base 1, for guiding the insertion and sliding of the second rod 22 (connected with the support structure 31 of the wheel supporting mechanism 3), so that the end of the second rod 22 towards the base 1 is adapted to move in the axial direction of the first rod 21 within the axial hole 212, in order to adjust the relative position of the first rod 21 and the second rod 22, and realize the height adjustment of the telescopic support mechanism 2; or the second rod 22 can be provided with an axial hole extending along the axial direction of the second rod 22 at the end away from the base 1, i.e. the axial hole extends from the end face of the end of the second rod 22 towards the base 1 along the axial direction of the second rod 22 away from the base 1, for guiding the insertion and sliding of the first rod 21, in order to adjust the relative position of the first rod 21 and the second rod 22, and realize the height adjustment of the telescopic support mechanism 2.

[0062] Moreover, the first rod 21 is provided with a first positioning hole 211, and the second rod 22 is provided with a second positioning hole 221 at a position corresponding to the first positioning hole 211; after the desired height of the telescopic support mechanism 2 is determined, the connecting piece 23 (such as a bolt structure) is inserted into the corresponding first positioning hole 211 and second positioning hole 221, so as to realize the stable connection of the first rod 21 and the second rod 22, thereby ensuring the stability and carrying capacity of the telescopic support mechanism 2 while realizing the height adjustment.

[0063] Exemplarily, in combination with Figure 1 , Figure 2 and Figure 4As shown, the first rod member 21 is of hollow structure, and the axial hole 212 thereof can be of circular, square or other regular shape in cross section to meet different operation requirements and structural strength requirements. The second rod member 22 is of cross section shape matching that of the axial hole 212, for example, when the axial hole 212 is circular, the second rod member 22 is designed to be of corresponding circular cross section; when the axial hole 212 is square or rectangular, the second rod member 22 is designed to be of square or rectangular cross section matching the axial hole 212. In some embodiments, the second rod member 22 is preferably in clearance fit with the first rod member 21 at the axial hole 212 to facilitate adjustment of the relative position of the second rod member 22 and the first rod member 21 while ensuring stability of the second rod member 22 and the first rod member 21 when connected by the connecting member 23, thereby ensuring stability of the wheel operation device during operation.

[0064] Alternatively, unlike the height adjustment of the telescopic support mechanism 2 realized by manual adjustment as described above, the telescopic support mechanism 2 can also be directly provided with a mechanism such as a hydraulic cylinder to facilitate automatic height adjustment, or the adjustment of the relative position of the first rod member 21 and the second rod member 22 of the telescopic support mechanism 2 can be realized by a hydraulic cylinder or motor driven mechanism.

[0065] Alternatively, the first positioning hole 211 is provided in multiple groups, the multiple groups of first positioning holes 211 are circumferentially spaced apart along the first rod member 21, and each group of first positioning holes 211 includes multiple first positioning holes 211 spaced apart along the axial direction of the first rod member 21.

[0066] Alternatively, the second positioning hole 221 is provided in multiple groups, the multiple groups of second positioning holes 221 are circumferentially spaced apart along the second rod member 22, and each group of second positioning holes 221 includes multiple second positioning holes 221 spaced apart along the axial direction of the second rod member 22.

[0067] In this embodiment, in order to improve the adjustment flexibility and positioning stability of the telescopic supporting mechanism 2, the first positioning hole 211 and / or the second positioning hole 221 can be designed as a multi-group distributed structure according to actual needs. Specifically, when the first positioning hole 211 adopts a multi-group distribution, a plurality of first positioning holes 211 are arranged on the first rod member 21 in a circumferential direction, and each group of first positioning holes 211 includes a plurality of hole structures (i.e., first positioning holes 211) arranged in the axial direction of the first rod member 21. In this way, the telescopic supporting mechanism 2 can realize height adjustment (i.e., adjust the relative position of the first rod member 21 and the second rod member 22) through the plurality of first positioning holes 211 arranged in the axial direction of the first rod member 21, and realize circumferential multi-angle adjustment, i.e., realize the rotation of the second rod member 22 relative to the first rod member 21 (around the axis of the first rod member 21), realize the rotation of the wheel supporting mechanism 3 connected with the second rod member 22 relative to the first rod member 21 (or the base 1), so as to enable the operator to select different working angles according to actual needs, and improve the adaptability of the wheel working device in different working scenarios. At the same time, the second positioning hole 221 on the second rod member 22 can be provided with one or more, by adjusting the relative position of the second rod member 22 and the first rod member 21, matching the first positioning hole 211 and the second positioning hole 221 for setting the connecting member 23, so as to realize the height and angle adjustment of the telescopic supporting mechanism 2.

[0068] When the second positioning hole 221 adopts a multi-group distribution, a plurality of second positioning holes 221 are arranged on the second rod member 22 in a circumferential direction, and each group of second positioning holes 221 includes a plurality of hole structures (i.e., second positioning holes 221) arranged in the axial direction of the second rod member 22. In this way, the telescopic supporting mechanism 2 can realize height adjustment (i.e., adjust the relative position of the first rod member 21 and the second rod member 22) through the plurality of second positioning holes 221 arranged in the axial direction of the second rod member 22, and realize circumferential multi-angle adjustment, i.e., realize the rotation of the second rod member 22 relative to the first rod member 21 (around the axis of the first rod member 21), realize the rotation of the wheel supporting mechanism 3 connected with the second rod member 22 relative to the first rod member 21 (or the base 1), so as to enable the operator to select different working angles according to actual needs, and improve the adaptability of the wheel working device in different working scenarios. At the same time, the first positioning hole 211 on the first rod member 21 can be provided with one or more, by adjusting the relative position of the second rod member 22 and the first rod member 21, matching the first positioning hole 211 and the second positioning hole 221 for setting the connecting member 23, so as to realize the height and angle adjustment of the telescopic supporting mechanism 2.

[0069] Optionally, in combination with Figure 1 , Figure 2 , Figure 4 ,Figure 5 and Figure 6 As shown in FIG. 2, the second rod member 22 includes a first connecting rod 222 and a second connecting rod 223, the second positioning hole 221 is arranged on the first connecting rod 222, and the first rod member 21 is connected with the first connecting rod 222 at the first positioning hole 211 and the second positioning hole 221 through the connecting member 23; one end of the second connecting rod 223 is connected with the first connecting rod 222 away from the first rod member 21, and the other end of the second connecting rod 223 is detachably connected with the wheel supporting mechanism 3; and the second connecting rod 223 is coaxially arranged with the wheel supporting mechanism 3, and the axis of the second connecting rod 223 is arranged at an angle with the axis of the first connecting rod 222.

[0070] In this embodiment, in order to realize the design that the axis of the wheel supporting mechanism 3 is arranged at an angle (acute angle or obtuse angle) with the horizontal plane, the second rod member 22 adopts a bending design. Specifically, the second rod member 22 includes a first connecting rod 222 and a second connecting rod 223, the first connecting rod 222 is used to realize the connection between the second rod member 22 and the first rod member 21, and is coaxially arranged with the first rod member 21; the second connecting rod 223 is used to be connected with the wheel supporting mechanism 3 (such as being connected with the support structure 31 of the wheel supporting mechanism 3), and is coaxially arranged with the wheel supporting mechanism 3; and in order to effectively reduce the space required by the wheel working device, the first rod member 21 is preferably vertically arranged, the angle between the axis of the second connecting rod 223 and the axis of the first connecting rod 222 is arranged at an angle (acute angle or obtuse angle), and the wheel supporting mechanism 3 is coaxially connected with the second connecting rod 223, so as to realize the design that the axis of the wheel supporting mechanism 3 is arranged at an angle with the horizontal plane, and then the rim 63 (or the appearance surface) of the to-be-worked wheel 6 forms a certain inclination angle with the horizontal plane after being installed on the wheel supporting mechanism 3, so that the operator has a more comfortable working view and operation space when performing deburring or inspection work, reduces the fatigue and strain of the operator caused by long-time side head, and significantly improves the working efficiency and working experience. The first connecting rod 222 and the second connecting rod 223 can be integrally formed or adopt a corresponding fixed connection mode, so as to ensure the structural strength of the second rod member 22 and the stability of the wheel supporting mechanism 3 supported by the second rod member 22 when the wheel supporting mechanism 3 is used to support the to-be-worked wheel 6 for work. In some embodiments, the angle between the axis of the second connecting rod 223 and the axis of the first connecting rod 222 is set according to actual needs.

[0071] Moreover, the end of the second connecting rod 223 away from the end connected with the first connecting rod 222 is detachably connected with the support structure 31, such as being connected in a plug-in, clamping or fastener manner, so as to realize the detachable connection, ensure the stability of the telescopic support mechanism 2 and the wheel supporting mechanism 3 when they are connected, and improve the convenience of assembly and disassembly between the telescopic support mechanism 2 and the wheel supporting mechanism 3.

[0072] As shown in Figure 1 , Figure 6 , for the wheel supporting mechanism 3 arranged at an included angle, the axis of the wheel supporting mechanism 3 and the horizontal plane (or the mounting plane) need to ensure that the wheel supporting mechanism 3 is located above the second rod 22 in the vertical direction, for example, the first rod 21 is vertically arranged, and the second rod 22 is at an obtuse angle with the first rod 21, so that the to-be-operated wheel 6 can be stably supported on the wheel supporting mechanism 3 under the cooperation of its own gravity and the positioning structure 32.

[0073] Optionally, the second rod 22 can be designed with an adjustable bending angle, that is, the included angle between the axis of the second connecting rod 223 and the axis of the first connecting rod 222 can be adjusted, so as to realize the adjustment of the bending angle of the second rod 22 and meet the different needs of the operator. For example, the second connecting rod 223 and the first connecting rod 222 are angle-locked through the corresponding locking structure (such as a fastener), when the angle needs to be adjusted, the locking structure is loosened for angle adjustment, and after the angle is adjusted, the locking structure is locked to realize angle locking.

[0074] Optionally, considering that the second rod 22 directly adopts a bending angle (that is, the included angle between the axis of the second connecting rod 223 and the axis of the first connecting rod 222) adjustable design, there may be a situation that the bending angle of the second rod 22 cannot be stably maintained, such as the bending angle adjustment part being worn and aged due to long-term use of the second rod 22, the bending angle of the second rod 22 being unable to be stably maintained due to the heavy weight of the supported wheel, and the like, which affects the operation efficiency and stability. In this embodiment, the second rod 22 does not need to adopt a bending angle adjustable design, and the second rod 22 and the first rod 21, and the second rod 22 and the wheel supporting mechanism 3 are detachably connected, which facilitates the direct replacement of the second rod 22. In this way, a plurality of second rods 22 with different bending angles can be pre-set for replacement to meet the different needs of the operator, prolong the service life of the second rod 22, and avoid the high cost caused by the bending angle adjustable design.

[0075] Optionally, as shown in Figure 2 , Figure 5 and Figure 6 , the wheel operating device further comprises a bearing 4; the second rod 22 further comprises a limiting portion 224 arranged in a ring shape along the outer peripheral wall of the second connecting rod 223, and the inner ring of the bearing 4 is sleeved on the second connecting rod 223 and abuts against the limiting portion 224; the wheel supporting mechanism 3 is provided with a sleeve structure 316 for sleeving on the outer ring of the bearing 4, and the sleeve structure 316 and the second connecting rod 223 are rotationally connected through the bearing 4.

[0076] In view of the fact that when the wheel supporting mechanism 3 cannot rotate, if the to-be-operated wheel 6 needs to be rotated to obtain the best visual range and the best operating angle required by the operator, the friction between the hub 61 of the to-be-operated wheel 6 and the contact surface of the wheel supporting mechanism 3 needs to be overcome, which is not only laborious, but also easy to cause scratches, damage, etc. on the hub 61 of the to-be-operated wheel 6 due to the friction when the to-be-operated wheel 6 and the wheel supporting mechanism 3 are relatively rotated, and is easy to cause unqualified products. Therefore, in the embodiment, the wheel supporting mechanism 3 is rotationally connected with the telescopic supporting mechanism 2, and the wheel supporting mechanism 3 is adapted to rotate around its own axis, so as to improve the flexibility of the wheel operating device during operation. At the same time of realizing the flexible rotation of the to-be-operated wheel 6 (i.e. the wheel supporting mechanism 3 and the to-be-operated wheel 6 supported on the wheel supporting mechanism 3 rotate synchronously), the wear of the to-be-operated wheel 6 caused by the sliding friction between the hub 61 of the to-be-operated wheel 6 and the wheel supporting mechanism 3 is effectively avoided.

[0077] Specifically, the outer peripheral wall of the second connecting rod 223 of the second rod member 22 is provided with a limiting portion 224 arranged in a ring shape, such as a ring-shaped groove structure or a ring-shaped protrusion structure, for forming a limiting step structure to limit the bearing 4 arranged on the second connecting rod 223 (i.e., limiting in the axial direction of the second connecting rod 223), ensuring the stable position of the bearing 4, and achieving stable installation between the bearing 4 and the second connecting rod 223, thereby improving the overall structural stability and reliability of the wheel working device. When the limiting portion 224 adopts a ring-shaped groove structure, the inner ring of the bearing 4 can be sleeved on the second connecting rod 223 and embedded in the ring-shaped groove structure, and the bearing 4 abuts against the groove wall of the ring-shaped groove structure to limit the bearing 4. When the limiting portion 224 adopts a ring-shaped protrusion structure, the inner ring of the bearing 4 can be sleeved on the second connecting rod 223 from the end of the second connecting rod 223 towards the wheel supporting mechanism 3, and the inner ring of the bearing 4 abuts against the end of the ring-shaped protrusion structure towards the wheel supporting mechanism 3 to limit the bearing 4, preventing the bearing 4 from moving away from the wheel supporting mechanism 3 on the second connecting rod 223. The bearing 4 with the inner ring sleeved on the second connecting rod 223 is coaxially arranged with the second connecting rod 223 to ensure that the second connecting rod 223 connected by the bearing 4 is coaxially arranged with the wheel supporting mechanism 3. Correspondingly, the end of the wheel supporting mechanism 3 towards the second connecting rod 223 is provided with a sleeve structure 316 (such as the sleeve structure 316 protruding from the side of the bottom plate 313 of the support structure 31 of the wheel supporting mechanism 3 away from the supporting plate 311) for sleeving on the outer ring of the bearing 4, and the inner wall of the sleeve structure 316 cooperates with the outer ring of the bearing 4, so that the bearing 4 achieves the rotary connection between the support structure 31 and the second rod member 22, and ensures the smooth and smooth relative rotation between the support structure 31 and the second rod member 22, so that the support structure 31 and the to-be-worked wheel 6 can freely rotate around the axis of the second rod member 22. Moreover, the bearing 4 achieves the rotary connection between the wheel supporting mechanism 3 and the telescopic support mechanism 2, greatly reducing the friction when the second rod member 22 rotates relative to the support structure 31, and improving the smoothness and stability when the wheel supporting mechanism 3 rotates relative to the telescopic support mechanism 2. The flexible angle adjustment capability of the wheel supporting mechanism 3 is provided to adapt to different working scene requirements. In addition, the design of the sleeve structure 316 sleeved on the outer ring of the bearing 4 also achieves the detachable connection (insertion fit) between the second connecting rod 223 and the support structure 31, which improves the convenience of assembly and disassembly between the wheel supporting mechanism 3 and the telescopic support mechanism 2 while ensuring the stability of the connection between the telescopic support mechanism 2 and the wheel supporting mechanism 3.

[0078] Optionally, in combination with Figure 1 and Figure 2 It is shown that the telescopic support mechanism 2 further includes a storage tray 5 connected with the base 1.

[0079] In the embodiment, the disposed storage tray 5 is used to collect the processed burr waste, so as to ensure the cleanness of the working environment, prevent the burr residues from scattering to other working areas or equipment, and improve the working efficiency and safety. The storage tray 5 is connected with the base 1, and the limited height of the storage tray 5 does not affect the flexibility of the operator in moving (such as moving around the wheel working device). In some embodiments, the storage tray 5 corresponds to the position of the wheel supporting mechanism 3, for example, the orthographic projection of the wheel supporting mechanism 3 on the installation plane falls on the storage tray 5, so that the processed burr directly falls into the storage tray 5 under the action of gravity, reduces the risk of burr scattering, and realizes the centralized collection and efficient processing of the burr.

[0080] Optionally, the side of the base 1 away from the first rod 21 is flush with the side of the storage tray 5 away from the first rod 21, so as to improve the contact area of the wheel working device and the installation plane, and further improve the stability of the wheel working device during operation.

[0081] Although the utility model discloses as above, the protection scope of the utility model disclosed is not limited to this. The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model disclosed, and these changes and modifications will fall within the protection scope of the utility model.
