The tire gripping devices shown in fig. 1, 2, and 3 may have the same structure or different partial structures.

Referring to fig. 1, 2 and 3, the tire clamping device according to the embodiment of the present invention includes a first rotary table 1, a second rotary table 2, a rotary shaft 3, at least two sets of supporting mechanisms 8, a first cylinder 4, and a first universal shaft assembly 5.

Wherein, first carousel 1 and second carousel 2 are all connected with pivot 3 rotation. Specifically, as shown in fig. 1, the rotary shaft 3 sequentially penetrates the first turntable 1 and the second turntable 2, so that the first turntable 1 can rotate around the rotary shaft 3 and the second turntable 2 can rotate around the rotary shaft 3. At this time, the first turntable 1 rotates about the same axis as the second turntable 2 rotates about. Wherein, first carousel 1 and second carousel 2 interval set up.

As shown in fig. 1 and 2, at least two linear guide rails 6 are disposed on the first rotary table 1, and the linear guide rails 6 are specifically groove structures or grooves on the first rotary table 1. At least two curved guide rails 7 are arranged on the second turntable 2, and the curved guide rails 7 are groove structures or grooves on the second turntable 2.

The first universal shaft assembly 5 includes a first universal shaft and a second universal shaft, which can relatively rotate in any direction. Wherein, the piston rod of the first cylinder 4 is fixedly connected with the first cardan shaft. The first cylinder 4 comprises a cylinder body and a piston rod which is telescopically movable relative to the cylinder body.

The cylinder body and the second cardan shaft of the first cylinder 4 are respectively connected with the first rotary table 1 and the second rotary table 2. For example, the cylinder body of the first cylinder 4 is connected with the first rotary table 1, and the second universal shaft is connected with the second rotary table 2; or the cylinder body of the first air cylinder 4 is connected with the second rotary table 2, and the second universal shaft is connected with the first rotary table 1.

The support mechanism 8 includes a first slider 81, a second slider 82, a first claw bar 83 fixedly attached to the first slider 81, a second claw bar 84 fixedly attached to the second slider 82, and a cross bar 85.

In each support mechanism 8, a cross bar 85 fixedly connects a first claw lever 83 and a second claw lever 84 outside the first turntable 1 and the second turntable 2. Through the connection of the cross bar 85, the first slider 81, the second slider 82, the first claw bar 83 fixedly connected to the first slider 81, the second claw bar 84 fixedly connected to the second slider 82, and the cross bar 85 can move synchronously.

In each support mechanism 8, a first slide 81 is slidably connected to a linear guide 6, and a second slide 82 is movably connected to a curvilinear guide 7. Thus, the linear guide 6 can guide the moving track of the first slider 81, and the curved guide 7 can drive and guide the movement of the second slider 82. The curved rail 7 can drive the second slider 82 to move by the contact between the rail and the second slider 82.

The first air cylinder 4 is used for controlling the relative rotation of the first rotary table 1 and the second rotary table 2 through the telescopic motion of a piston rod of the first air cylinder 4. Specifically, when a piston rod of the first air cylinder 4 performs extension movement, the first rotary table 1 and the second rotary table 2 are controlled to relatively rotate in a target rotation direction; when the piston rod of the first air cylinder 4 performs contraction movement, the first rotary table 1 and the second rotary table 2 are controlled to rotate relatively in the direction opposite to the target rotation direction. The target rotation direction is, for example, clockwise, and a direction opposite to the target rotation direction is, for example, counterclockwise.

The linear guide 6 and the curved guide 7 are used for guiding the first slider 81 and the second slider 82 to move away from or close to the rotating shaft 3 when the first rotating disk 1 and the second rotating disk 2 rotate relatively. Specifically, the curved guide rail 7 can drive the second slider 82 to move, and the cross bar 85 is fixedly connected with the first claw bar 83 and the second claw bar 84, so that the first claw bar 83 and the second claw bar 84 can move synchronously through the cross bar 85. The second slide 82 drives the first slide 81 to move by driving the cross bar 85, the first claw bar 83 and the second claw bar 84. When the first rotary table 1 and the second rotary table 2 relatively rotate in the target rotation direction, the linear guide rail 6 and the curved guide rail 7 guide the first sliding block 81 and the second sliding block 82 to move away from the rotating shaft 3; the linear guide 6 and the curved guide 7 guide the first slider 81 and the second slider 82 to move close to the rotary shaft 3 when the first rotary table 1 and the second rotary table 2 are relatively rotated in a direction opposite to the target rotation direction. Thus, the first slider 81 and the second slider 82 can guide the cross bar 85, the first claw lever 83, and the second claw lever 84 to move relative to the rotary shaft 3. The moving tracks of the first sliding block 81 and the second sliding block 82 of the same supporting mechanism 8 relative to the rotating shaft 3 are the same, so that the first sliding block 81 and the second sliding block 82 of the same supporting mechanism 8 can move synchronously.

The support mechanism 8 is for supporting the inner ring of the tire via the cross bar 85, the first claw lever 83, and the second claw lever 84. Wherein, the utility model discloses the tire can be waste tire.

Specifically, the first cylinder 4 controls the relative rotation of the first rotary table 1 and the second rotary table 2 through the telescopic motion of the piston rod, so that the linear guide rail 6 and the curved guide rail 7 can guide the first slider 81 and the second slider 82 to move away from or close to the rotary shaft 3.

When the first cylinder 4 controls the first rotary table 1 and the second rotary table 2 to rotate relatively through the extension movement of the piston rod, the cross rod 85, the first claw rod 83 and the second claw rod 84 of the supporting mechanism 8 extend out relative to the first rotary table 1 and the second rotary table 2, and the cross rod 85, the first claw rod 83 and the second claw rod 84 can support the inner ring of the tire so as to clamp the tire.

When the first cylinder 4 controls the first rotary table 1 and the second rotary table 2 to rotate relatively in opposite directions through contraction movement of the piston rod, the cross rod 85, the first claw rod 83 and the second claw rod 84 of the supporting mechanism 8 contract relatively to the first rotary table 1 and the second rotary table 2, and at this time, the cross rod 85, the first claw rod 83 and the second claw rod 84 can release the inner ring of the tire to realize separation of the tire clamping device and the tire.

Thus, the first claw lever 83 and the second claw lever 84 move forward and backward along with the displacement of the first slider 81 and the second slider 82, so that the cross bar 85, the first claw lever 83 and the second claw lever 84 can be clamped and loosened.

The tire gripping device may be disposed in various directions, for example, one end of the rotating shaft 3 is fixedly connected to an external moving device. Thus, the external moving device can control the movement of the tire gripping device by moving the rotating shaft 3.

In the embodiment of the present invention, the linear guide 6 and the curved guide 7 have multiple specific implementations. In a particular example, as shown in fig. 2 and 3, the linear guide 6 is parallel to the radial direction of the target, wherein the radial direction of the target is perpendicular to the axis around which the first rotary table 1 rotates. The different curved guide rails 7 have the same shape of their extending tracks, and the curved guide rails 7 are arranged in a central symmetry around the axis around which they rotate around the second turntable 2. Thus, the first sliding blocks 81 of different supporting mechanisms 8 have the same moving track under the guidance of the linear guide 6; the second sliding blocks 82 of different supporting mechanisms 8 are guided by the curved guide rails 7 and have the same moving track. Thereby, it is achieved that the cross bar 85, the first claw lever 83 and the second claw lever 84 of the different support mechanisms 8 move the same distance telescopically with respect to the rotary shaft 3. This ensures as much as possible that the centre of the tyre gripping device or the centres of the support means 8 coincide with the centre of the tyre.

The number of the linear guide rails 6 and the curved guide rails 7 can be set according to the number of the supporting mechanisms 8. For example, as shown in fig. 2 and 3, the number of the linear guides 6 is four, the number of the curved guides 7 is four, and the number of the support mechanisms 8 is four. Wherein, the moving directions of the cross bars 85 of two adjacent supporting mechanisms 8 are mutually vertical. Therefore, the utility model discloses device is got to tire clamp is comparatively balanced to the clamp force of tire inner circle, can press from both sides to the tire tighter.

It should be understood that the number of linear guides 6, curved guides 7, and support mechanisms 8 may be other numbers.

In order to drive the first turntable 1 and the second turntable 2 to rotate relatively smoothly, the tire clamping device optionally further comprises a second air cylinder 9 and a second universal shaft assembly 10.

The second universal shaft assembly 10 includes a third universal shaft and a fourth universal shaft, and the third universal shaft and the fourth universal shaft can relatively rotate in any direction. The piston rod of the second cylinder 9 is fixedly connected with the third cardan shaft, so that the second cylinder 9 can drive the third cardan shaft to move.

In the embodiment of the present invention, the telescopic motion of the piston rod of the first cylinder 4 and the piston rod of the second cylinder 9 has the same effect on the relative rotation of the first turntable 1 and the second turntable 2. Namely, when the piston rod of the first air cylinder 4 and the piston rod of the second air cylinder 9 extend out, the first rotary table 1 and the second rotary table 2 relatively rotate in one direction; when the piston rod of the first air cylinder 4 and the piston rod of the second air cylinder 9 contract, the first rotating disc 1 and the second rotating disc 2 relatively rotate in opposite directions.

The embodiment of the utility model provides an in, the side fixed connection of the cylinder body of first cylinder 4 and first carousel 1, the side fixed connection of second cardan shaft and second carousel 2. The first air cylinder 4 can drive the first rotary table 1 and the second rotary table 2 to rotate relatively through the first universal shaft assembly 5. And the cylinder body of the second air cylinder 9 is fixedly connected with the side surface of the second rotating disc 2, and the fourth universal shaft is fixedly connected with the side surface of the first rotating disc 1. The second air cylinder 9 can drive the first rotary disk 1 and the second rotary disk 2 to rotate relatively through a second universal shaft assembly 10. Thus, the relative rotation of the first turntable 1 and the second turntable 2 has two power sources, so that the rotation can be driven more smoothly.

A first cylinder 4, a first cardan shaft assembly 5, a second cylinder 9 and a second cardan shaft assembly 10 are arranged around the shaft 3 between the first turntable 1 and the second turntable 2. In this way, the first rotary table 1 and the second rotary table 2 are more uniformly powered by the first air cylinder 4 and the second air cylinder 9, so that the first rotary table 1 and the second rotary table 2 can stably rotate relatively.

In the embodiment of the present invention, there are various specific connection manners of the first slider 81 and the linear guide 6, for example, in the example of fig. 2, the first slider 81 includes a slider main body 86 and a bump, the bump is disposed on the side portion of the slider main body 86, and the bump is slidably connected with the linear guide 6 in the linear guide 6. In this way, the moving locus of the first slider 81 can be guided by the linear guide 6 to guide the moving locus of the bump. Wherein, the first claw bar 83 is fixedly connected with the middle part of the slide block main body 86. At this time, the linear guide 6 is radially spaced from the target. Thus, the extension distance of the linear guide 6 can be made short, and the first slider 81 can be ensured to move smoothly.

In the embodiment of the present invention, there are various specific connection manners of the second slider 82 and the curved guide 7, for example, in the example shown in fig. 3, the supporting mechanism 8 further includes a roller, and the roller is connected to the second slider 82, for example, the roller includes a roller shaft and a rolling main body, and the roller shaft penetrates through the roller main body, so that the roller main body can rotate relative to the roller shaft. The axle is fixedly connected to the second slider 82. In the present example, the rollers are in rolling connection with a curved guide 7. Thus, the rolling friction can reduce the friction force of the second slider 82 on the curved guide rail 7, so that the second slider 82 can move more smoothly on the curved guide rail 7.

Alternatively, as shown in fig. 2 and 3, the first turntable 1 and the second turntable 2 are both circular structures.

In a specific example, in the supporting mechanism 8, one end of the cross bar 85 is fixedly connected to the end of the first claw bar 83 away from the first slider 81, and the other end of the cross bar 85 is fixedly connected to the end of the second claw bar 84 away from the second slider 82. In this way, when the support mechanism 8 supports the inner ring of the tire, the cross bar 85 can abut against the inner ring of the tire, and the abutment of the support mechanism 8 against the tire is more stable.

In order to allow the first slider 81 to move more smoothly, the tire gripping device may further include an auxiliary cylinder 11.

In other words, the first support mechanism and the second support mechanism are two support mechanisms 8 in the four sets of support mechanisms 8, and the moving directions of the cross bar 85 of the first support mechanism and the cross bar 85 of the second support mechanism are opposite. Thus, the auxiliary cylinder 11 can drive the first sliding block 81 of the first supporting mechanism and the first sliding block 81 of the second supporting mechanism to move towards or away from each other, and the auxiliary cylinder 11 can also provide power for the two first sliding blocks 81 except for the power provided by the driving of the second turntable 2 to the first supporting mechanism and the second supporting mechanism by the first sliding block 81 of the first supporting mechanism and the first sliding block 81 of the second supporting mechanism. Thus, the movement of the two first sliders 81 is smoother.

For convenience of connection, the tire gripping device may optionally further include a first link 12 and a second link 13.

The first connecting rod 12 is fixedly connected with the first sliding block 81 of the first supporting mechanism, and the second connecting rod 13 is fixedly connected with the first sliding block 81 of the second supporting mechanism.

In this way, the auxiliary cylinder 11 connects and drives the first slider 81 of the first support mechanism and the first slider 81 of the second support mechanism through the first link 12 and the second link 13. The installation of the auxiliary cylinder 11 is facilitated by the installation position provided by the first and second connecting rods 12 and 13.
