[0018] Example 1

[0019] like Figure 1 、 Figure 2 and Figure 3 The micro-cycloid pinwheel planetary reducer pin gear housing tooth groove grinder quick fixing device shown includes a detachable base 100 and a detachable base countersunk screw hole 1001.

[0020] A circular boss 1002 is provided on one side of the detachable base 100.

[0021] A horizontal sliding groove 1003 is provided on one side of the symmetrical center line of the detachable base 100.

[0022] The edge of the detachable base 100 is provided with a transverse screw hole 1004 for use with the horizontal slide groove 1003.

[0023] A fixed transition plate 102 is provided at a right angle to the edge of the detachable base 100 and the horizontal slide 1003.

[0024] A fixed clamping plate 1021 is provided on the surface of the fixed transition plate 102.

[0025] An adjusting slider 103 is provided in the horizontal slide groove 1003.

[0026] The surface of the adjusting slider 103 is provided with a moving transition plate 1031.

[0027] The two end surfaces of the dynamic transition plate 1031 are symmetrically provided with dynamic clamping plates 1032.

[0028] An adjusting slider through hole 1033 is provided in the adjusting slider 103.

[0029] The horizontal slide 1003 is provided with a screw 104 and a screw locking nut 1042 in the horizontal direction through the horizontal screw hole 1004.

[0030] One end surface of the screw 104 is provided with a multi-angle adjustment portion 1041.

[0031] One end of the screw rod 104 passes through the adjusting slider 103 through the adjusting slider through hole 1033 , and a set of adjusting nuts 1043 used in conjunction with the adjusting slider 103 are provided on the screw rod 104 .

[0032] The clamping working principle is:

[0033] (1) Loosen the screw lock nut 1042 counterclockwise;

[0034] (2) The screw rod 104 is rotated counterclockwise by the multi-angle adjustment portion 1041. At this time, the screw rod 104 moves horizontally away from the fixed transition plate 102. In this way, the adjustment slider 103 at one end of the screw rod 104 moves in the horizontal sliding groove 1003 to the same side as the screw rod 104.

[0035] (3) Place the needle gear housing workpiece horizontally on the side of the fixed transition plate 102 and the fixed clamping plate 1021 on the surface of the circular boss 1002. At this time, rotate the screw 104 clockwise through the multi-angle adjustment part 1041. At this time, the screw 104 moves horizontally toward the side close to the fixed transition plate 102. In this way, the adjustment slider 103 at one end of the screw 104 moves to the same side as the screw 104 in the horizontal slide groove 1003. At this time, the movable transition plate 1031 and the movable clamping plate 1032 on the adjustment slider 103 are close to the needle gear housing workpiece, and the needle gear housing workpiece is clamped with the fixed transition plate 102 and the fixed clamping plate 1021. Then, advance the screw locking nut 1042 clockwise to lock the screw 104.

[0036] When removing the clamp, just follow steps (1) and (2).

[0037] In addition, preferably, the fixed transition plate 102 and the movable transition plate 1031 are respectively set to arc structures and have the same size, so that most of the needle gear housing workpiece can be tightly covered and clamped firmly and stably, ensuring the accuracy of the tooth groove processing of the needle gear housing workpiece.

[0038] In addition, the adjusting slider 103 and the horizontal sliding groove 1003 are preferably configured as a bar structure for use in conjunction with each other, which can achieve convenient assembly, use and adjustment control.

[0039] In addition, the connection surface of the detachable base 100 and the circular boss 1002 is preferably set to a boss shape, which makes the multi-size adjustment control operation convenient and does not interfere with each other.

[0040] The micro-cycloid pinwheel planetary reducer pin gear housing tooth groove grinder quick fixing device of this structure is adaptable and practical and can be conveniently assembled on the grinding machine for use.
