[0005] The present invention aims at the above-mentioned problems existing in the prior art and provides a rim clamping device. The technical problem to be solved by the present invention is: how to improve the convenience of operation.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A rim clamping device comprises a mounting seat, wherein two sides below the mounting seat are provided with a clamping jaw 1 and a clamping jaw 2 which can move toward or in opposite directions. The device is characterized in that a connecting plate is provided below the mounting seat, a connecting rod is provided on the connecting plate, the connecting rod is slidably connected to the mounting seat, the upper end of the connecting rod passes through the mounting seat, a limiting ring is provided on the upper end of the connecting rod, and a proximity switch is provided on the mounting seat.

[0008] Its working principle is:

[0009] The rim is transported on the plate chain line and stops when it blocks the photoelectric switch. At this time, the robot's manipulator moves the rim clamping device to the top of the rim, and then the rim clamping device slowly descends with the manipulator. The connecting plate presses the rim and starts to rise. The connecting plate pushes the connecting rod to rise, and the limit ring on the connecting rod rises. When the proximity switch senses the limit ring, the manipulator stops descending, and then the clamping jaws 1 and 2 move towards each other and clamp the rim. Then the manipulator grabs the rim clamping device and moves it. The rim clamping device places the rim in a suitable position, thereby achieving the clamping, handling and stacking of the rim. This rim clamping device is suitable for clamping rims of sizes such as 10 inches and 12 inches.

[0010] The rim clamping device can accurately determine the clamping time and position of the rim through proximity switch sensing, conveniently and accurately clamp the rim, greatly improving the convenience of operation and also improving work efficiency.

[0011] In the above-mentioned rim clamping device, the lower half of the connecting rod is sleeved with a connecting column, and the upper half of the connecting rod is sleeved with a spring, and the spring is located between the bottom of the mounting seat and the top of the connecting column.

[0012] When the connecting plate starts to rise after being pressed against the wheel rim, the spring is in a compressed state. When the first and second clamping jaws are released to lower the wheel rim, the spring pushes the connecting column downward, causing the connecting plate to automatically reset, further improving the convenience of operation.

[0013] In the above-mentioned rim clamping device, the connecting plate is square, the middle part of the connecting plate is hollowed out, and there are four connecting rods, each of which is distributed at a corner of the connecting plate.

[0014] Two of the four are respectively located at the corners of the connecting plate, which play a good guiding role and improve the stability of the connecting plate when it moves. The middle part of the connection is hollowed out, and the rims are against the edges of the connecting part when in use. This structure does not affect the use function and saves materials.

[0015] In the above-mentioned rim clamping device, a bearing is sleeved on the connecting rod, and the bearing is mounted on the mounting seat.

[0016] The connecting rod is slidably connected to the mounting seat through a bearing, which greatly improves the stability of the connecting plate when it moves.

[0017] In the above-mentioned rim clamping device, a cylinder is installed at the bottom of the mounting seat, and one side and the other side of the cylinder are respectively provided with piston rod 1 and piston rod 2, and the clamping jaw 1 and clamping jaw 2 are respectively installed on piston rod 1 and piston rod 2.

[0018] The first gripper, the second gripper and the cylinder form a mechanical gripper. When the first piston rod and the second piston rod are contracted, the first gripper and the second gripper move toward each other, and vice versa, the first gripper and the second gripper move in opposite directions.

[0019] In the above-mentioned rim clamping device, the bottoms of the first clamping jaw and the second clamping jaw are respectively provided with bosses, and the bosses are provided with grooves, and the shape of the grooves is adapted to the shape of the rim.

[0020] The first clamping jaw and the second clamping jaw clamp the rim respectively through the bosses at the bottom. The grooves on the bosses are adapted to the shape of the rim, and can fit more closely with the rim during clamping, thereby improving the stability of the clamping.

[0021] In the above-mentioned rim clamping device, a bracket is installed on the mounting seat, and the proximity switch is installed on the bracket.

[0022] In the above-mentioned rim clamping device, the proximity switch is located on one side of the connecting rod, and the limiting ring can be directly opposite to the proximity switch.

[0023] Compared with the prior art, the advantages of the present invention are as follows:

[0024] The rim clamping device can accurately determine the clamping time and position of the rim through proximity switch sensing, conveniently and accurately clamp the rim, greatly improving the convenience of operation and also improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0029] like Figure 1-2As shown, the rim clamping device includes a mounting seat 1, and jaws 1 2 and jaws 2 3 that can move toward or in the opposite directions are arranged on both sides below the mounting seat 1, a connecting plate 4 is arranged below the mounting seat 1, and a connecting rod 5 is arranged on the connecting plate 4. The connecting rod 5 is slidably connected to the mounting seat 1, and the upper end of the connecting rod 5 passes through the mounting seat 1. A limiting ring 6 is arranged on the upper end of the connecting rod 5, and a proximity switch 7 is arranged on the mounting seat 1.

[0030] The rim 17 is transported on the plate chain line and stops when it blocks the photoelectric switch. At this time, the robot's manipulator moves the rim clamping device to the top of the rim, and then the rim clamping device slowly descends with the manipulator. The connecting plate 4 presses the rim and starts to rise. The connecting plate 4 pushes the connecting rod 5 to rise, and the limit ring 6 on the connecting rod 5 rises. When the proximity switch 7 senses the limit ring 6, the manipulator stops descending, and then the clamping jaw 1 2 and the clamping jaw 2 3 move toward each other and clamp the rim 17. Then the manipulator grabs the rim clamping device and moves it. The rim clamping device places the rim 17 in a suitable position, thereby achieving the clamping, handling and stacking of the rim 17. This rim clamping device is suitable for clamping rims 17 of sizes such as 10 inches and 12 inches.

[0031] like Figure 1 As shown, in this embodiment, the lower half of the connecting rod 5 is sleeved with a connecting column 8, and the upper half of the connecting rod 5 is sleeved with a spring 9, which is located between the bottom of the mounting seat 1 and the top of the connecting column 8.

[0032] When the connecting plate 4 starts to rise after being pressed against the wheel rim, the spring 9 is in a compressed state. When the clamping jaws 1 2 and 2 3 are released to lower the wheel rim 17, the spring 9 pushes the connecting column 8 to move downward, so that the connecting plate 4 is automatically reset, further improving the convenience of operation.

[0033] like Figure 1 As shown, in this embodiment, the connecting plate 4 is square, the middle of the connecting plate 4 is hollowed out, and there are four connecting rods 5, each connecting rod 5 is distributed at the corners of the connecting plate 4.

[0034] The four wheels are respectively located at the corners of the connecting plate 4, playing a good guiding role and improving the stability of the connecting plate 4 when moving. The middle part of the connection is hollowed out, and the rim 17 rests against the edges of the connection part when in use. This structure does not affect the use function and saves materials.

[0035] like Figure 1 As shown, in this embodiment, a bearing 10 is sleeved on the connecting rod 5, and the bearing 10 is mounted on the mounting seat 1. The connecting rod 5 is slidably connected to the mounting seat 1 through the bearing 10, which greatly improves the stability of the connecting plate 4 when it moves.

[0036] like Figure 1As shown, in this embodiment, a cylinder 11 is installed at the bottom of the mounting base 1, and one side and the other side of the cylinder 11 are respectively provided with a piston rod 12 and a piston rod 2 13, and a clamping jaw 1 2 and a clamping jaw 2 3 are respectively installed on the piston rod 12 and the piston rod 2 13.

[0037] The clamping jaw 1 2 , the clamping jaw 2 3 and the cylinder 11 constitute a mechanical clamp. When the piston rod 1 12 and the piston rod 2 13 are contracted, the clamping jaw 1 2 and the clamping jaw 2 3 move toward each other, and vice versa, the clamping jaw 1 2 and the clamping jaw 2 3 move in opposite directions.

[0038] like Figure 1 As shown, in this embodiment, the bottom of the clamping jaw 1 2 and the clamping jaw 2 3 has a boss 14 , and a groove 15 is formed on the boss 14 . The shape of the groove 15 is adapted to the shape of the rim 17 .

[0039] The first clamping jaw 2 and the second clamping jaw 3 clamp the rim 17 respectively through the boss 14 at the bottom. The groove 15 on the boss 14 is adapted to the shape of the rim 17, and can fit more closely with the rim 17 during clamping, thereby improving the stability of clamping.

[0040] like Figure 1 As shown, in this embodiment, a bracket 16 is installed on the mounting base 1 , and the proximity switch 7 is installed on the bracket 16 .

[0041] like Figure 1 As shown, in this embodiment, the proximity switch 7 is located on one side of the connecting rod 5 , and the limiting ring 6 can be directly opposite to the proximity switch 7 .

[0042] The proximity switch 7 is close to the connecting rod 5 where the limit ring 6 is located. When the limit ring 6 rises to a certain height, it is directly opposite to the proximity switch 7. This structure makes it easier for the proximity switch 7 to sense and detect the limit ring 6, accurately determine the time suitable for clamping the rim 17, and improve the sensitivity of the operation.

[0043] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
