Description

Technical Field

[0001] The utility model relates to a fixing fixture, in particular to a fixing fixture for auxiliary machining of a limiting nut, belonging to the technical field of mechanical machining auxiliary tools. Background Art

[0002] In the machining industry, the machining accuracy of the limit nut directly affects its performance and life. However, during the machining process, due to the small size of the nut itself and the need to control its machining position and angle with high precision, a limit nut machining auxiliary fixing fixture is required;

[0003] Among them, the "A clamp for nut processing" disclosed in the application number "202321279816.3" is also an increasingly mature technology, which includes a fixed rod, a base adjustment mechanism and a clamping mechanism, and the clamping mechanism is installed on the base adjustment mechanism; the clamping mechanism includes a first clamping block, a second clamping block, a fixed rod, a ring sleeve, a sliding rod, a rubber pad, a third screw rod and a conical clamping block, and the first clamping block and the second clamping block are both fixedly connected to the base adjustment mechanism. The utility model overcomes the shortcomings of the prior art. When in use, when the third screw rod moves to the left, it will abut against the bottom end of the sliding rod and gradually push the sliding rod outward, and the nut to be processed is placed on the ring sleeve. The three outward sliding rods push the rubber pad and make it tightly against the inner side of the nut to be processed. The position of the second clamping block is adjusted to clamp the nut to be processed from the side. When the edge of the nut is cut, even if the nut rotates, it will not deviate from the center, and has good stability;

[0004] However, the above method still has the following defects in actual use: the third screw rod pushes the sliding rod outward through the conical clamping block to clamp the nut, but when the clamping operation is performed next time, the sliding rods on both sides of the bottom cannot complete automatic resetting due to gravity, which affects the placement of the nut on the ring sleeve. The staff is required to manually adjust the length of the sliding rod, which is inconvenient to operate. At the same time, during the processing, debris is easy to fall on the surface of the first screw rod, which is easy to affect the normal movement of the slider. Utility Model Content
