Referring to fig. 1 and fig. 2, which respectively show a perspective view of a wheel clamping device for clamping a wheel 600 and a perspective view of the wheel clamping device in one direction according to an embodiment of the present invention, the wheel clamping device includes a moving module 100, a driving module 200, a clamping module 300, and a clamping portion 400. The mobile module 100 includes two mobile units 110 disposed opposite to each other. The driving module is connected to the two mobile units 110, and is used for driving the two mobile units 110 to move close to or away from each other, and the moving distances of the two mobile units 110 are the same. The clamping module 300 includes two clamping jaws 310 disposed opposite to each other, one clamping jaw 310 is correspondingly installed on one mobile unit 110, and the clamping jaw 310 includes a clamping portion 312. The clamping portion 400 is connected to the driving module 200, and the clamping portion 400 is located at a central position between the clamping portions 312 of the two clamping jaws 310 along the moving direction of the moving unit 110. The two jaws 310 are adapted to cooperatively grip the tire 610 of the outer wheel 600 such that the grip is aligned with the center of the hub 620 of the wheel 600.
Referring to fig. 2, in conjunction with fig. 1, the mobile module 100 includes two mobile units 110 disposed opposite to each other. One of the moving units 110 includes a moving body 111 and two wings 112 connected to the moving body 111, wherein one end of the two wings 112 is connected to the moving body 111, and the other end extends away from the other moving unit 110.
Referring to fig. 2 and fig. 1, the driving module 200 includes two guide rods 210 and a screw rod 220. The two guide rods 210 are arranged in parallel, one end of each guide rod 210 is fixed by a connecting plate 230, and the other end of each guide rod 210 is fixed by another connecting plate 230. The two moving units 110 are provided with two guide holes (not shown) parallel to each other and respectively matched with the two guide rods 210, and the two guide rods 210 are respectively inserted into the two guide holes, so that each moving unit 110 is slidably matched with the two guide rods. The screw 220 is disposed parallel to the guide rods 210 and located at the center between the two guide rods 210, that is: the two guide rods 210 are axisymmetric relative to the screw rod 220; along the axial direction of the screw rod 220, both ends of the screw rod are respectively fixed with the two connecting plates 230, and the screw rod 220 can only rotate around the circumferential direction. The screw 220 includes a first screw portion and a second screw portion, the first screw portion and the second screw portion have opposite rotation directions and equal thread pitches, one of the moving units 110 is in threaded engagement with the first screw portion, and the other moving unit 110 is in threaded engagement with the second screw portion. Then, by rotating the screw 220, the two moving units 110 can be driven to move toward or away from each other at the same time, so that the two moving units 110 can move closer to or farther away from each other, and the moving distances of the two moving units 110 are the same. It is understood that in other embodiments of the invention, the number of guide rods may be other numbers than one.
With reference to fig. 2, the clamping module 300 includes two opposite clamping jaws 310, and one clamping jaw 310 is correspondingly mounted on one of the moving units 110. The clamping jaw 310 includes a connecting portion 311 and a clamping portion 312. The connecting portion 311 is mounted on the wing portion 112 of the mobile unit 110, and is used for connecting the clamping portion 312 and the mobile unit 110. The connecting portion 311 is a flat plate-shaped structure, and has one end connected to one end of the clamping portion 312 close to the moving unit 110 and the other end extending in a direction close to the other clamping jaw 310. One end of the clamping portion 312 is connected to one end of the connecting portion 311 away from the other clamping jaw 310, and the other end extends in a direction away from the moving unit 110, so that a predetermined included angle is formed between the clamping portion 312 and the connecting portion 311. In this embodiment, the number of the clamping modules 300 is two, and the two clamping modules 300 are respectively disposed on two sides of the screw rod 220 and are axisymmetric with respect to the screw rod 220.
Further, since most of the circumferential surfaces of the tire 610 are provided with a plurality of anti-slip grooves distributed in a circumferential array around the axis of the tire 610, in order to facilitate the better gripping of the tire 610 by the gripping module 300, thereby avoiding a situation where one gripping jaw 310 is gripped inside a groove and another gripping jaw 310 is gripped outside the groove, at least one gripping jaw 310 is pivotally connected to the corresponding moving unit 110, so that the gripping portion of the at least one gripping jaw 310 can slide along the circumferential surface (i.e. the cylindrical side surface of the tire) of the tire 610, thereby adapting to the groove structure on the circumferential surface of the tire 610. It is worth noting that: by "at least one jaw" in this paragraph is understood at least one jaw in the wheel clamp device, namely: when the number of the clamping modules 300 is one group, at least one of the two clamping jaws is pivotally connected with the corresponding moving unit, and when the number of the clamping modules 300 is more than two groups, at least one of the more than four clamping jaws is pivotally connected with the corresponding moving unit. Furthermore, "pivotal connection" in this paragraph means a rotational connection between two parts connected to each other by a shaft-like element.
Referring to fig. 3 and 4, a partially exploded view of the wheel clamping device and a partially enlarged view of a portion a are shown, respectively, in conjunction with fig. 1 and 2; in the present embodiment, each of the clamping jaws 310 is rotatably connected to the corresponding moving unit 110 by the first connecting shaft assembly 320. Specifically, for each clamping jaw 310, one end of the first connecting shaft assembly 320 is fixed to one end of the connecting portion 311 close to the corresponding moving unit 110, and the other end extends to one end away from the corresponding clamping portion 312; the corresponding mobile unit 110 is provided with a first connection hole 113 adapted to the first connection shaft assembly 320 at one end close to the connection part 311; the first coupling shaft assembly 320 is inserted into the first coupling hole 113 to rotatably couple the clamping jaw 310 to the corresponding moving unit 110. It is understood that in other embodiments of the present invention, the first connection hole 113 may also be disposed at the connection portion of the clamping jaw 310, and accordingly, the first connection shaft assembly 320 is disposed at the corresponding moving unit 110; in addition, the moving unit 110 and the clamping jaw 310 may be pivotally connected by other means, such as hinge, bearing connection, etc., which is not limited herein.
Further, in order to facilitate the detachment and installation of the clamping jaws 310 while ensuring the fixation of the clamping jaws 310 in the non-operating state (not in the tire-clamping state) along the axial direction of the first connecting shaft assembly 320, the first connecting shaft assembly 320 includes a first connecting shaft (not shown) and a first elastic rubber ring (not shown). Wherein, the one end of the first connecting shaft is fixed in the one end that connecting portion 311 is close to mobile unit 110, and the other end extends towards the direction that deviates from corresponding clamping part 312, and first connecting shaft inserts first connecting hole 113, and first elastic rubber ring cover is located first connecting shaft and with first connecting hole 113 interference fit. Since the first elastic rubber ring has an elastic characteristic, on the one hand, it can mount the holding jaw 310 to the mobile unit by interference fit with the first connection hole 113, and on the other hand, it can also leave from the first connection hole 113 by elastic deformation.
In some embodiments, to allow the jaws 310 to rotate only through a small angular range, thereby avoiding excessive freedom of the jaws 310 to facilitate adjustment of their positions, the wheel clamping apparatus further includes a second coupling shaft assembly 330. In particular, the axis of the second connecting shaft assembly 330 is arranged parallel to the axis of rotation of the clamping jaw 410, which in particular comprises a second connecting shaft (not shown), namely: the second connecting shaft is disposed parallel to the first connecting shaft assembly 320. The second connecting shaft is also fixed at one end of the connecting portion 311 close to the wing portion 112 and extends in a direction away from the clamping portion 312; the corresponding moving unit 110 is provided with a second connecting hole 114 at one end close to the connecting portion 311, the diameter of the second connecting hole 114 is slightly larger than that of a second connecting shaft, the second connecting shaft is inserted into the second connecting hole 114, and because a certain margin exists between the inner wall of the second connecting hole and the second connecting shaft, the margin enables the clamping jaws to rotate only slightly, so that the two clamping jaws 310 are clamped on the surface of the circumferential surface of the tire 610 or clamped on the groove of the circumferential surface of the tire 610 at the same time. It is understood that in other embodiments of the present invention, the second connection hole may also be disposed at the connection portion 311, and accordingly, the second connection shaft is disposed at the corresponding moving unit.
Further, in order to prevent the second connecting shaft from frequently rotating when the clamping jaw 310 is in the non-working state, and thus causing damage to the second connecting shaft and/or the second connecting hole, the second connecting shaft assembly further comprises a second elastic rubber ring (not shown). The second elastic rubber ring is sleeved on the second connecting shaft and is in interference fit with the second connecting hole. The second elastic rubber ring is arranged to constrain the second connecting shaft to be in a stable state on one hand so as to prevent the second connecting shaft from freely rotating; on the other hand, when the second connecting shaft has a rotation tendency under the action of external force, the second elastic rubber ring can be extruded and deformed under the action of external force, so that the second connecting shaft is displaced, and the clamping jaw 310 rotates relative to the first connecting shaft assembly 320 within a small angle range. In addition, the interference fit between the second elastic rubber ring and the second connecting hole can also facilitate the disassembly and assembly of the clamping jaw 310, so that users can replace clamping jaws of different specifications.
In some embodiments, to ensure a better grip of the tyre 610 by the clamping jaw 310, the clamping portion 312 is provided with at least two serrations 313 towards one end of the other clamping jaw 310, the at least two serrations 313 being arranged in parallel along the direction in which the clamping portion 312 extends. In the process that the two clamping jaws 310 clamp the tire 610 together, because the tire is made of an elastic material, the tips of the saw teeth 313 can press the surface of the tire 610, so that the contact surface between the tire 610 and the clamping portion 312 is in a saw-tooth shape, and the slip between the clamping jaws 310 and the tire 610 can be effectively avoided.
In some embodiments, in order to ensure that the clamping force between the two jaws 310 and the tire 610 is as large as possible during the clamping of the tire 610 by the two jaws 310, the clamping portion 312 may be deformed under the reaction force of the tire 610: along the extending direction of the clamping portion 312, one end of the clamping portion 312 close to the connecting portion 311 may move toward the moving unit 110 relative to one end of the clamping portion 312 away from the connecting portion 311, and the included angle between the connecting portion 311 and the clamping portion 312 is enlarged. When the angle is greater than 90 degrees, the clamping effect of the two clamping jaws 310 is relatively poor. In order to overcome the defects, the preset included angle in the free state is designed to be smaller than 90 degrees. That is, when the clamping portion 312 is deformed to be perpendicular to the connecting portion 311, there is already a sufficiently large clamping force between the clamping portion 312 and the tire 610, which is larger than the clamping force required for the wheel clamping device; so that the included angle between the connecting part and the clamping part is not more than 90 degrees all the time in the process of clamping the wheel 600.
Referring to fig. 2, the spacer 500 is mounted on the moving unit 110 for preventing the connecting portion 311 from contacting the outer hub 620 during the process of clamping the outer tire 610 by the two clamping jaws 310. In this embodiment, the spacers 500 are elastic rubber pads, the connecting portion 311 of each clamping jaw 310 is provided with the spacers 500 on the side facing the corresponding clamping portion, and the spacers 500 extend from one end of the connecting portion 311 of the clamping jaw 310 far away from the corresponding clamping portion 312 to one end close to the corresponding clamping portion 312, that is: the elastic rubber pad is indirectly mounted to the moving unit 110 through the clamping jaws 310. When the end surface of the hub 620 of the wheel 600 protrudes beyond the end surface of the tire 610, the spacer 500 is configured to abut against the end surface of the hub 620 when the two clamping jaws of the clamping module cooperate to clamp the tire 610, thereby avoiding the contact between the connection portion 311 and the end surface of the hub 620. Optionally, the elastic rubber pad (spacer) is a rubber pad or a silicone rubber pad, and it is understood that, in other embodiments of the present invention, the elastic rubber pad (spacer) may also be other rubber pads with elasticity, which is not described in detail herein; the spacer may also be directly mounted to the moving body or the wing of the moving unit as long as it can prevent the first connecting part from contacting the hub; in addition, the spacer may be provided at the connecting portion of only one of the grip claws in the same wheel clamp device.
It should be understood that the spacer 500 is not limited to the elastic rubber pad disposed at the above position, but the spacer 500 can prevent the connecting portion 311 from contacting the hub 620 during the process of clamping the tire 610 by the two clamping jaws 310. For example: fig. 5 and 6 show a perspective view of a wheel clamp with another spacer 500' and an enlarged view of a portion of B, respectively, in conjunction with fig. 1-4; the connecting portion 311 of each clamping jaw 310 is provided with a spacer 500 'on the side surface facing the corresponding clamping portion 312, and the spacer 500' extends from one end of the connecting portion 311 close to the corresponding clamping portion 312 to one end far away from the corresponding clamping portion 312. The spacer 500' is used to abut against the end surface of the tire 610 when the two jaws are cooperatively clamped on the tire 610, so that a gap is formed between the connecting portion 311 and the hub 620, and the connecting portion 311 is prevented from contacting the hub 620. Alternatively, the spacer 500' is integrally formed with the connecting portion 311, and is made of a metal material; of course, the material of the spacer 500' is not limited in particular, and may be rubber, silicon rubber, or other materials. It is worth mentioning that the spacer 500' itself only contacts the end face of the tire 610, not the hub 620. When the spacer 500 provided by the first embodiment abuts against the hub 620, friction still exists between the spacer 500 and the hub 620, and although the elastic rubber pad adopted by the spacer 500' does not damage the hub 620, the friction still may cause certain influence on the movement process of the two clamping jaws; compared with the prior art, the spacer 500 'provided by the present embodiment not only enables the two clips to avoid the hub 620 as a whole, but also does not contact with the hub 620, so the spacer 500' has better isolation effect.
Referring to fig. 2, the clamping portion 400 is fixedly mounted on the driving module 200 and located between the two moving units 110 through the two guide rods 210. The clamping portion is located at the center between the clamping portions 312 of the two clamping jaws of the same clamping module 300 along the extending direction of the moving unit 110, and the clamping portion is used for installing detection elements such as a laser and a target. Then, when the two moving units 110 are simultaneously moved toward the center until the two clamping jaws 310 of the same clamping module 300 are clamped on the surface of the tire 610, the clamping portion is exactly aligned with the center of the wheel hub.
The wheel clamping device provided by the embodiment of the invention comprises a moving module 100, a driving module 200, a clamping module 300 and a clamping part 400. The mobile module 100 includes two mobile units 110 disposed opposite to each other. The driving module is connected to the two mobile units 110, and is used for driving the two mobile units 110 to move close to or away from each other, and the moving distances of the two mobile units 110 are the same. The clamping module 300 includes two clamping jaws 310 disposed opposite to each other, one clamping jaw 310 is correspondingly installed on one mobile unit 110, and the clamping jaw 310 includes a clamping portion 312. The clamping portion 400 is connected to the driving module 200 and is located at a central position between the clamping portions 312 of the two clamping jaws 310 in the moving direction of the moving unit 110. The two jaws 310 are adapted to cooperatively grip the tire 610 of the outer wheel 600 such that the grip is aligned with the center of the hub 620 of the wheel 600. With the above arrangement, the clamping jaws 310 need only clamp against the circumferential surface of the tire 610, and the clamping force generated by the wheel clamping device does not damage the hub 620. In addition, the wheel clamping device can also ensure that the clamping part is aligned with the center of the hub after the two clamping jaws 310 are clamped in place.
It should be understood that even though the clamping jaws and the corresponding moving units are connected by the first connecting shaft assembly and the second connecting shaft assembly in the above embodiments, the present invention is not limited thereto, and in other embodiments of the present invention, the clamping jaws 310 may be detachably mounted on the corresponding moving units 110 by other methods, so as to facilitate the replacement of clamping jaws 310 with different specifications.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; within the idea of the invention, also technical features in the above embodiments or in different embodiments may be combined, steps may be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
