Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a workpiece transfer table. Background Art

[0002] In existing machining, when a workpiece needs to complete multiple processes on different machine tools, a joint robot is usually used to connect the processes. However, the movable angle of the joint robot is limited after all, and it is difficult to achieve the posture transformation of the workpiece between two adjacent processes by relying solely on the joint robot.

[0003] In view of this situation, technicians in this field can easily think of using a fixed split-type gripper between the two machines to complete the transfer of the workpiece, that is, the articulated manipulator clamps the workpiece that has completed a sequence of processing and feeds it from one side into the split-type gripper. After the split-type gripper clamps the workpiece, the articulated manipulator re-grasps the workpiece from the other side to complete the posture transformation of the workpiece (for example, the articulated manipulator originally grasps one end of the workpiece, and after the workpiece is placed in the split-type gripper, the articulated manipulator can grasp it from the other end of the workpiece). However, in practice, the workpiece that has completed a sequence of processing will be attached with waste chips and cutting fluid, so direct transfer will easily lead to inaccurate positioning and inaccurate grasping angle problems. Utility Model Content

[0004] The utility model aims to solve the above problems existing in the prior art and proposes a workpiece transfer table to solve the problem that the workpiece cannot be accurately grasped due to inaccurate positioning.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A workpiece transfer table comprises a frame and a transfer gripper arranged on the top of the frame, characterized in that a box is fixedly connected to the top of the frame, a clearance opening is provided on the top of the box, an air blow pipe is arranged in the box, an air outlet end of the air blow pipe faces the clearance opening, a square opening is provided on one side of the box, and a chip collection drawer is provided in the box which is inserted from the square opening.

[0007] Before the transfer, the joint manipulator first clamps the workpiece and extends it into the box through the clearance port, and uses the air blow pipe set in the box to blow the workpiece to clean the waste chips and cutting fluid. After the workpiece is cleaned, the joint manipulator transports the workpiece to the transfer gripper from one side. After the transfer gripper clamps and fixes the workpiece, the joint manipulator re-clamps the workpiece from the other side to complete the posture transformation of the workpiece. The waste chips and cutting fluid cleaned from the workpiece are discharged into the chip collection drawer for collection. After a certain amount has accumulated, the chip collection drawer can be directly pulled out of the box for cleaning.

[0008] This workpiece transfer table integrates an air blowing function on the basis of the transfer function, so that the workpiece can be cleaned before the transfer, thereby ensuring that the workpiece can be accurately positioned during the transfer, so that the articulated robot can accurately clamp the workpiece during the transfer.

[0009] In the above-mentioned workpiece transfer table, the air blowing tube is a copper tube.

[0010] A copper tube is used as the air blow tube, so that the air blow tube can be bent on site according to actual conditions to ensure that it can clean the workpiece more thoroughly.

[0011] In the above-mentioned workpiece transfer table, a lower hopper is fixedly connected to the box body, and the chip collection drawer is located below the lower hopper.

[0012] The lower hopper is fixedly connected to the box body, so that the waste chips and cutting fluid cleaned from the workpiece can be better collected and discharged into the chip collection drawer.

[0013] In the above-mentioned workpiece transfer table, an air blowing joint is fixedly connected to the wall of the lower hopper, the air inlet end of the air blowing pipe is connected to the air outlet end of the air blowing joint, and the bottom of the box body is provided with a pipe penetration hole.

[0014] The air blowing joint is fixedly connected to the wall of the lower hopper, and a pipe hole is set at the bottom of the box body, so that the air supply pipe can be inserted into the box body from the bottom of the box body and connected to the air outlet of the air blowing joint, and then the air inlet end of the air blowing pipe is connected to the air outlet end of the air blowing joint, thereby completing the connection of the entire air blowing pipeline. The lower hopper is used for collecting chips and installing and fixing the air blowing joint, achieving dual purposes.

[0015] In the above-mentioned workpiece transfer table, a gas tank is fixedly connected inside the frame, and a pipe outlet hole 1 is provided on the top of the frame, and the pipe outlet hole 1 is located below the box body.

[0016] In practice, an air supply pipe is led out from the gas tank and then passes through the outlet hole 1 and the through-hole to the box body and connected to the air inlet end of the air blowing joint, so that the gas tank can be used to supply air to the air blowing pipe. Through the above arrangement, the structure of the entire workpiece turntable is more compact and smaller in size.

[0017] In the above-mentioned workpiece transfer table, the top of the frame is fixedly connected to a box body, and the top of the frame is also provided with two pipe outlet holes connected to the inner cavity of the box body. The transfer claw is connected to the top of the box body, and the top of the box body is provided with a pipe passing groove.

[0018] The two air supply pipes are connected to the gas tank and then passed through the second outlet hole, the inner cavity of the box body and the pipe groove in sequence and then connected to the transfer gripper, so that the gas tank can also be used to supply air to the transfer gripper at the same time. Through the above arrangement, the structure of the entire workpiece transfer table becomes further simple.

[0019] Compared with the existing technology, this workpiece transfer table has the following advantages:

[0020] 1. By fixing the box on the top of the frame and setting an air blowing pipe in the box, the air blowing function is integrated on the basis of the transfer function. In this way, the workpiece can be cleaned before the transfer to ensure that the workpiece can be accurately positioned during the transfer, so that the articulated robot can accurately clamp the workpiece during the transfer;

[0021] 2. Both the transfer gripper and the air blow pipe are supplied with air by the gas tank installed in the frame, making the structure of the entire workpiece transfer table more concise and smaller in size. BRIEF DESCRIPTION OF THE DRAWINGS
