Abstract

The ER nut is a nut that is installed on the CNC tool holder together with the ER collet. At present, there are few ER nut wrenches on the market. They are generally open and thin in thickness. They cannot hold the ER nuts well, and they are easy to scratch the nuts, damage the tools and workpieces, and even cause more serious consequences. The utility model discloses an ER nut wrench, which comprises three parts which are sequentially connected: a wrench head, a wrench rod and an insulating rubber handle. The wrench head is in a fully closed form, and the inner wall of the wrench head is in contact with the outer wall of the ER nut at 360°. When the nut is stuck, Clamp from the top of the nut; the wrench head is hexagonal stepped or grooved. The upper part of the hexagonal stepped wrench head is a hexagonal cylinder and the lower part is a cylinder. The upper part of the grooved wrench head has 6 grooves and the lower part is a cylinder; The thickness of the wrench head is greater than the thickness of the upper part of the ER nut, and when in use, the upper structure of the ER nut and the cylinder of the lower part of the ER nut are stuck. It is suitable for the disassembly and assembly of ER nuts, OZ (ball) nuts and strong nuts with the same external structure.

Description

A kind of ER nut wrench

【Technical field】

The utility model relates to the field of assembly and disassembly tools, in particular to an ER nut wrench.

【Background technique】

The ER nut is a nut that is installed on the CNC tool holder together with the ER collet. ER collet is translated from "ER-chuck", also known as spring collet, which is a cylindrical fixture used to fasten tools. After the ER nut is clamped with the ER collet, use a wrench to tighten it on the CNC tool holder.

At present, there are few ER nut wrenches on the market. They are generally open and thin in thickness. They cannot hold the ER nuts well, and they are easy to scratch the nuts, damage the tools and workpieces, and even cause more serious consequences.

【Content of invention】

In order to overcome the deficiencies in the background technology, the utility model discloses an ER nut wrench, which is suitable for the disassembly and assembly of ER nuts, OZ (ball) nuts and powerful nuts with the same external structure.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

The ER nut wrench consists of three parts: the wrench head 1, the wrench rod 2 and the insulating rubber handle 3 connected in sequence. The wrench head is fully enclosed. The inner wall of the wrench head contacts the outer wall of the ER nut at 360°. Live; wrench head hexagonal step or groove type, the upper part of the hexagonal step wrench head is a hexagonal cylinder, the lower part is a cylinder, the upper part of the groove type wrench head has 6 grooves, and the lower part is a cylinder; the thickness of the wrench head is greater than The thickness of the upper part of the ER nut is used to clamp the upper structure of the ER nut and the cylinder of the lower part of the ER nut.

Figure 3 is the hexagonal stepped ER nut and the corresponding wrench head;

Figure 4 shows the grooved ER nut and the corresponding wrench head.

In the figure: 1. Wrench head; 2. Wrench rod; 3. Non-slip rubber handle; 4. Hexagonal step ER nut wrench 5. Groove ER nut wrench

【detailed description】

The present invention can be explained in more detail by the following examples, and the purpose of disclosing the utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:

With reference to the accompanying drawings, the ER nut wrench includes three parts: a wrench head, a wrench rod, and a non-slip rubber handle.

The specific implementation method adopts the following technical solutions:

The wrench head is fully enclosed, the inner wall of the wrench head is in contact with the outer wall of the ER nut at 360°, and when the nut is stuck, it is stuck from above the nut; the hexagonal step or groove type of the wrench head, the upper part of the hexagonal stepped wrench head is a hexagonal cylinder , The lower part is a cylinder, the upper part of the grooved wrench head has 6 grooves, and the lower part is a cylinder; the thickness of the wrench head is greater than the thickness of the upper part of the ER nut, and the upper structure of the ER nut and the lower part of the cylinder of the ER nut are stuck when used; applicable Suitable for disassembly and assembly of ER nuts, OZ (ball) nuts and strong nuts with the same external structure.
