Description

Technical Field

[0001] The utility model belongs to the technical field of manipulators, in particular to a transporting fixture for manipulators. Background Art

[0002] Manipulators are commonly used mechanical equipment in automated production. They can be used to grab and carry various parts and equipment, which can greatly improve work efficiency. However, manipulators need to be driven by mechanical arms, so they need a larger range of space. At the same time, parts also need to have clamping space, so conventional manipulators need to clamp the maximum shape of the parts. However, some parts do not have clamping space on the outside, so screw holes are punched in the corners of the upper surface, and then the lifting screws are screwed in to facilitate lifting and handling. However, this method requires crane handling, which is difficult to use with manipulators, resulting in low production efficiency. Summary of the invention

[0003] In order to solve the above technical problems, a technical solution adopted by the utility model is:

[0004] A handling fixture for a robot, comprising a housing portion and a clamping portion installed in the housing portion;

[0005] The housing portion comprises an upper shell and a lower shell fixedly connected to one side of the upper shell, the upper shell and the lower shell form a cavity, and a sealing member is provided on a side of the upper shell away from the lower shell;

[0006] The clamping part comprises a clamping member for clamping and carrying and a driving member for driving the clamping member, and the driving member is connected to the clamping member through a connecting member.

[0007] Furthermore, the driving member includes a first driving block and a second driving block, at least three balls are provided between the first driving block and the second driving block, the balls are located in the third driving block and rotate, and the upper shell is also provided with a first air inlet connector and a second air inlet connector. When high-pressure gas is passed into the first air inlet connector, the first driving element block is pushed and the balls are squeezed, thereby pushing the second driving block to move upward. When high-pressure gas is passed into the second air inlet connector, the second driving block can be driven to move downward.

[0008] Furthermore, the connecting member includes a connecting sleeve arranged in the lower shell and a connecting rod arranged in the connecting sleeve, a first elastic element for resetting the connecting sleeve is provided between the connecting sleeve and the third driving block, and one end of the connecting rod is connected to the second driving block.

[0009] Furthermore, the clamping member includes at least two groups of clamping blocks, an opening and closing block for driving the clamping blocks to open and close, and a control head for accommodating the clamping blocks and the opening and closing blocks. The opening and closing blocks and the clamping blocks are provided with mutually cooperating wedging inclined surfaces. The wedging inclined surfaces control the opening and closing of the clamping blocks in the control head. The control head is fixedly connected to the connecting sleeve, and the control head is also covered with a second elastic element for resetting the clamping block.

[0010] Furthermore, a third elastic element is also provided on the first driving member, and the third elastic element is used for safety protection after gas is cut off.

[0011] Furthermore, a gap is left between the connecting sleeve and the third driving block, and the gap is less than 3 mm.

[0012] Beneficial effects of the utility model:

[0013] 1. The opening and closing block and the clamping block of the utility model are provided with mutually cooperating wedging inclined surfaces, and the wedging inclined surfaces control the opening and closing of the clamping block in the control head. As long as the fixture is inserted into the handling process hole, the clamping block can support the hole wall, and parts can be quickly transported even in a small operating space.

[0014] 2. At the same time, there is a gap between the connecting sleeve and the third driving block. The function of the gap is to correct the error. That is, when the clamping block is opened to support the hole of the part, there may be an error due to incomplete contact with the upper surface of the part. At this time, the part is lifted up and the control head is withdrawn into the remaining gap to compensate for the plane error and ensure the positioning accuracy during transportation.

Example

[0023] like Figures 1 to 5 As shown, a handling fixture for a robot comprises a housing portion 1 and a clamping portion 2 installed in the housing portion 1;

[0024] The housing portion 1 comprises an upper shell 11 and a lower shell 12 fixedly connected to one side of the upper shell 11, the upper shell 11 and the lower shell 12 form a cavity, and a sealing member 13 is provided on the side of the upper shell 11 away from the lower shell 12;

[0025] The clamping part 2 includes a clamping member 23 for clamping and carrying and a driving member 21 for driving the clamping member 23, and the driving member 21 is connected to the clamping member 23 through a connecting member 22. Specifically, the driving member 21 includes a first driving block 211 and a second driving block 212, and three balls 214 are arranged between the first driving block 211 and the second driving block 212, and the balls 214 are located in the third driving block 213 and rotate. Specifically, a gap H is left between the connecting sleeve 221 and the third driving block 213, and the gap is 2mm. The function of the gap is to correct the error, that is, when the clamping block is opened to support the hole of the part, there may be an error of incomplete contact with the upper surface of the part, and at this time, the part is lifted, the control head retreats, and enters the remaining gap H to compensate for the non-contact plane error. After the part is released, the first elastic element is reset. The upper shell 11 is also provided with a first air inlet connector 215 and a second air inlet connector 216. When the first air inlet connector 215 is fed with high-pressure gas, the first driving element block 211 is pushed and the ball 214 is squeezed, thereby pushing the second driving block 212 to move upward. The second driving block is connected to the connecting rod, that is, the connecting rod is pulled to move upward. When the second air inlet connector 216 is fed with high-pressure gas, the second driving block 212 can be driven to move downward. Specifically, the first driving member 211 is also provided with a third elastic element 217, which is used for safety protection after gas is cut off. Even if an accident occurs and the high-pressure gas is cut off, the third elastic element will also press down, so that the clamping block is opened to avoid the parts falling due to gas cut off during transportation. Specifically, the connecting member 22 includes a connecting sleeve 221 disposed in the lower shell 12 and a connecting rod 223 disposed in the connecting sleeve 221. A first elastic element 222 for resetting the connecting sleeve 221 is disposed between the connecting sleeve 221 and the third driving block 213. One end of the connecting rod 223 is connected to the second driving block 212. Specifically, the clamping member 23 includes at least two groups of clamping blocks 233, an opening and closing block 231 for driving the clamping blocks 233 to open and close, and a control head 232 for accommodating the clamping blocks 233 and the opening and closing blocks 231. The opening and closing blocks 231 and the clamping blocks 233 are provided with mutually cooperating wedging inclined surfaces, and the wedging inclined surfaces control the opening and closing of the clamping blocks 233 in the control head 232. The control head 232 is fixedly connected to the connecting sleeve 221. The control head 232 is also covered with a second elastic element 234 for resetting the clamping blocks 233.
