For that can further appreciate that the contents, features and effects of the utility model, the following examples are hereby given, and coordinates attached drawing
Detailed description are as follows.It should be noted that the present embodiment is descriptive, it is not restrictive, cannot thus limits this practicality
Novel protection domain.
A kind of rolling thread rolling machine, including engine base 2 and fixture block 1, are wherein equipped with multiple fixture blocks, and multiple fixture blocks on engine base
It is slidably connected with engine base, is clamped with screw plate between fixture block, and clamping for fixture block is formed with multiple positioning grooves 7 on face；
Screw plate bottom is formed with positioning plate 3, which is formed with multiple locating convex blocks 8 with positioning groove cooperation limit, and fixed
Thread rolling processing block 4 has integrally been made at the top of the plate of position.
The preferred technical solution of the utility model is：It is formed with thread rolling teeth 5 at the top of thread rolling processing block.
In addition, the utility model is preferred, and when screw plate is located at the Working pasition such as Fig. 2, Fig. 3, positioning plate bottom and machine
Backing plate is installed to clearance fit between seat top, which can carry out face support to screw plate bottom, coordinate and determine on fixture block
Locating convex block on position groove and positioning plate carries out high intensity, high-precision fixed limit to screw plate.
In addition, the utility model is preferred, the contact surface of positioning plate and fixture block is made as inclined surface, and angle of inclination is preferred
It is 85 °.
In addition, the utility model is preferred, the fixture block that the fixed board of screw plate is all made of to the utility model with movable plate clamps
Positioning, its advantage is that：1, positioning plate height is adjusted, thread rolling processing block is made to stretch out upwards, until screw plate bottom is higher than fixture block
Upper surface, the design can be achieved after cutting reparation thread rolling teeth processing to multiple the regrinding of thread rolling processing block progress, still can guarantee stranding
The thread rolling working height of silk processing block, makes the thread rolling processing block in screw plate be fully used；2, it is installed in actual production
The engine base of screw plate (fixed board) 11 and screw plate (movable plate) 9 will produce relative sliding and the adjustment of relative distance, but right
In different service lifes, the different screw plates for repairing number, the fixture block and backing plate using the utility model are needed, to screw plate
Working height be finely adjusted, its purpose is to ensure that fixture block clamps the chucking power of screw plate (fixed board) and screw plate (movable plate)
It is identical, two pieces of screw plate unbalance stress are prevented, stripped thread, even rolling screw 10 of threading off such as break at dangerous occur caused by.
In addition, the utility model is preferred, the contact surface of positioning plate and fixture block is made as inclined surface, and angle of inclination is preferred
