Installation tool

Installation wire thread wire thread insert sleeve need to use special tools, including dedicated wire thread insert tap wire thread insert installation wrench, thrust, a wire thread sleeves and thread bottom plug sleeve, wherein the tap for processing wire thread insert mounted prepared hole, for mounting the wrench mounting wire thread, for mounting thrust thrust caudal peduncle, detachable sleeves for the collar, bottom outlet plug for checking the installation of the blind hole .

1. Bottom hole tap: used for the processing of the internal thread of the wire thread insert. Since the external thread of the wire thread insert is a non-standard thread, this type of tap is different in size from the ordinary M tap.

2. Installation wrench: used to install the wire thread insert in the threaded bottom hole. The basic principle is to make the wire thread thread

sleeve pass through a section of the guide thread to force the outer diameter of the wire thread thread sleeve to shrink so that it can be inserted into the bottom hole smoothly. It is divided into manual type And automatic type.

3. Breaker: The purpose of the breaker is mainly to break the installation handle of the wire threaded sleeve, especially for the through hole, the installation handle must be broken.

4. Sleeve remover: used to take out the threaded screw sleeve installed in the threaded hole of the base. For the screw sleeve that needs to be replaced after long-term use, and when it needs to be taken out due to improper installation or thread tripping during installation, etc. use.

5. Thread plug gauge: used to detect the internal thread bottom hole of the wire thread insert. After the wire thread insert is installed, the accuracy of the internal thread formed depends on the profile manufacturing tolerance of the wire thread insert and the internal thread bottom hole of the wire thread insert. tolerance.

Classification

Installation preparation tools: ST taps, CR-MO alloy drill bits, compressed air spray gun (optional)

Installation tools: ST special wrenches, which are divided into manual wrenches and automatic wrenches, among which manual wrenches are divided into simple wrenches and socket wrenches (commonly used);

Automatic wrenches are divided into electric wrenches and pneumatic wrenches (usually used for batch installation screw sleeves, mounting brackets can be equipped)

Breaking tool: Breaker, used to break screw sleeves with mounting handles, no tail screw sleeves do not need to be used

Removal tool: unloading device, used to remove the screw sleeve that failed to install

Installation steps

1. Drilling

2. Tapping

3. Installation

4. Break the mounting handle

5. How to remove the wire thread insert

Installation inspection

After the wire thread insert is installed, the threaded hole tolerance zone depends on the profile manufacturing tolerance of the wire thread insert and the thread tolerance zone of the wire thread insert mounting hole. The former is controlled by the wire thread insert manufacturer, and the latter mainly depends on the tapping of the wire thread insert mounting hole. The wire precision usually forms 6H grade. When the precision is high, it can reach 5H and 4H tolerance bands. The unified thread standard is 2B and 3B. Corresponding level plug gauges can be used to detect the thread of the bottom hole.
