Description

Technical Field

[0001] This utility model belongs to the field of nut technology, specifically relating to a tapping fixture for nut processing. Background Technology

[0002] A nut is a fastener that is screwed onto a bolt or threaded rod to secure a fastener. It's an essential component in all manufacturing machinery. Based on the material, nuts are categorized into several types, including carbon steel, stainless steel, and non-ferrous metals (such as copper). Nuts are used to tightly connect mechanical equipment; only nuts and bolts of the same specifications can be connected through their internal threads. Types of nuts include self-locking nuts, lock nuts, locking nuts, four-prong nuts, screw-in nuts, safety nuts, thin-thread screw connecting nuts, self-locking hexagonal cap nuts, nuts for special anchor screws, hexagonal crown nuts, and eye nuts. Metal hexagonal flange face lock nuts, all-metal hexagonal flange face lock nuts, fine-pitch non-metallic insert hexagonal flange face lock nuts, and fine-pitch hexagonal flange face nuts. During the tapping process, tapping fixtures are needed to fix the nuts. However, current tapping fixtures often use clamping plates to hold and fix the nuts. Since the nuts are hexagonal, it is not possible to effectively clamp the edges and corners of the nuts. This can easily cause the nuts to wobble during subsequent tapping, resulting in nut displacement and affecting the quality of nut processing. Therefore, a tapping fixture specifically for nut processing is needed. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides a tapping fixture for nut processing. It solves the problem that current tapping fixtures often use clamping plates to hold and fix nuts during use. Since the nuts are hexagonal, the clamping plates cannot effectively hold the edges and corners of the nuts, which easily leads to the nuts shaking during subsequent tapping processes, causing the nuts to shift and affecting the quality of nut processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tapping fixture for nut processing, comprising a support plate, a discharge hole on the upper surface of the support plate, a nut body on the top of the support plate, a positioning block fixedly installed on one side of the upper surface of the support plate, a first corner groove on one side of the positioning block, a support block fixedly installed on the other side of the upper surface of the support plate, a first electric push rod fixedly installed on one side of the support block, a clamping block fixedly connected to one end of the first electric push rod, a second corner groove on one side of the clamping block, a slot on the surface of the positioning block, a U-shaped connecting plate fixedly installed on the other side of the positioning block, a second electric push rod fixedly installed on the inner wall of the U-shaped connecting plate, a discharge top block fixedly connected to one end of the second electric push rod, a connecting plate fixedly installed on the surface of the support plate, a third electric push rod fixedly installed on one side of the connecting plate, and a push plate fixedly connected to one end of the third electric push rod.

[0005] Preferably, the clamping block is located on one side of the positioning block, and both the first corner slot and the second corner slot are triangular.

[0006] Preferably, the surface of the clamping block is provided with a rubber anti-slip pad.

[0007] Preferably, the unloading top block is located inside the slot opening.

[0008] Preferably, one side of the push plate is provided with an anti-slip groove, and there are several anti-slip grooves.

[0009] Preferably, a collection box is provided at the bottom of the support plate, and a debris box is provided on the lower surface of the support plate.

[0010] Preferably, support legs are fixedly installed on both sides of the bottom of the support plate, and mounting holes are provided on the surface of the support legs.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] After the first electric push rod is started, it can drive the clamping block to move. After the clamping block is moved and adjusted, it can abut against the corner of the nut body and push the nut body so that the corner of the nut abuts into the first corner slot on one side of the positioning block. The first corner slot and the second corner slot cooperate with each other to clamp and fix the corner of the nut, so that the corner of the nut achieves a locking effect, preventing the nut from shifting during subsequent tapping and ensuring the quality of nut processing.
