[0002] An end effector clamp is a fixture used to connect an end effector to the end of a manipulator. Usually, two clamping holes are arranged on its surface to respectively clamp the connection ends of the manipulator end and the end effector.

[0003] At present, the finish machining of end effector clamps is mostly completed by a CNC machining center, but there is a lack of relevant fixtures. Each time, only one end effector clamp can be clamped, and the operation is troublesome. At the same time, the positioning accuracy of repeated clamping is not good, which needs to be improved.

[0006] A five-axis fixture for machining end effector clamps includes a fixture body fixedly installed on a turntable of a servo turntable through bolts. A plurality of convex discs are circumferentially distributed on the outer wall of the fixture body. The outer diameter of the convex disc is adapted to the aperture of the first clamping hole on the end effector clamp. A screw rod is fixedly passed through the convex disc through a mounting hole. After passing through the first clamping hole, the screw rod is cooperatively connected with a nut. A U-shaped pressing plate is sleeved on the outer wall of the screw rod between the nut and the end effector clamp.

[0007] As a further scheme of the utility model: A second clamping hole is opened on the end effector clamp. An opening groove communicated with the second clamping hole is opened on the outer wall of the end effector clamp. A bolt hole is penetrated through the corresponding position of the outer wall of the end effector clamp and the opening groove.

[0008] As a further scheme of the utility model: A second threaded hole is opened at the corresponding position of the outer wall of the fixture body and the bolt hole.

[0009] As a further scheme of the utility model: A stop block is arranged on the outer wall of the fixture body on one side of each second threaded hole.

[0010] As a further scheme of the utility model: The outer diameter of the nut is smaller than the inner diameter of the first clamping hole.

[0011] As a still further scheme of the utility model: A positioning rod is threadedly connected to the convex disc through a first threaded hole. The positioning rod passes through the first clamping hole. A positioning groove adapted to the positioning rod is opened on the inner side of the U-shaped pressing plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] By using the servo turntable provided in the utility model, the fixture body can be adjusted at multiple angles. In cooperation with the use of a numerical control machining center, the various end effector clamps clamped on the fixture body can be machined from multiple angles. When clamping the end effector clamp on the fixture body, only need to put the first clamping hole on the convex disc, then connect the bolt passing through the bolt hole with the second threaded hole, and then tighten the nut to press the U-shaped pressing plate against the end effector clamp, so as to achieve precise positioning of the end effector clamp. The operation is simple, the positioning accuracy of repeated clamping is high, and the use effect is good. Description of the Drawings

[0022] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, a five-axis fixture for end effector clamp processing includes a fixture body 2 fixedly installed on the turntable of a servo turntable 1 through bolts. A plurality of convex discs 3 are circumferentially distributed on the outer wall of the fixture body 2. The outer diameter of the convex disc 3 is adapted to the aperture diameter of a first clamping hole 14 on the end effector clamp 13. A screw rod 5 is fixedly passed through the convex disc 3 through a mounting hole 4. After passing through the first clamping hole 14, the screw rod 5 is cooperatively connected with a nut 10. A U-shaped pressing plate 8 is sleeved on the outer wall of the screw rod 5 between the nut 10 and the end effector clamp 13. A second clamping hole 15 is formed in the end effector clamp 13. An opening groove 16 communicating with the second clamping hole 15 is formed on the outer wall of the end effector clamp 13.
