Abstract
A kind of T-nut disclosed by the utility model, shape are diamond shape, and two sides are equipped with step, and step is equipped with screw hole.The problems such as the utility model is intended to provide a kind of solution for efficiently clamping and positioning in mechanical processing process, is had a single function with solving common T-nut, and dress takes the hidden danger such as inconvenience.
Description
Technical field
The utility model relates to efficiently clamp and position in technical field of mechanical processing, especially machine tool mechanical process
Technical field.
Background technique
In machining, for the positioning requirements for meeting workpiece or tooling, T-nut attachment screw is generallyd use to work
Part/tooling is held, as shown in Figure 1.
In the actual operation process, this method has the following problems:
1) T-nut has a single function, and is only capable of using as retaining piece；
2) T-nut need to be put into from the end of lathe keyway or indentation, there, then slide into holding position, low efficiency, time-consuming
It is long；
3) when use is finished or damaged, T-nut need to be taken out again from the end of lathe keyway or indentation, there, low efficiency, consumption
Duration.
Summary of the invention
A kind of T-nut disclosed by the utility model, it is desirable to provide one kind in mechanical processing process efficiently clamping and
The problems such as solution of positioning is had a single function with solving common T-nut, and dress takes the hidden danger such as inconvenience.
The utility model technical solution is:
A kind of T-nut, shape are diamond shape, and two sides are equipped with step, and step is equipped with screw hole.
The T-nut center is equipped with threaded hole, and threaded hole is half pin hole of half-thread.
The T-nut width is less than lathe keyway notch, and T-nut length is greater than lathe keyway width of rebate.
The cooperation precision of half pin hole of half-thread and pin in the T-nut is H grades.
T-nut is done diamondwise by the utility model, convenient for quickly placing and taking in lathe keyway；In T-block
Two threaded holes are opened up, can be provided T-nut in keyway with screw；T-nut original thread hole is changed to half-thread
Half pin hole makes it have positioning/fixing double action；The agility for improving T-nut installation, taking out；Increase T-nut
Use scope, make it have positioning/fixing double action.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is existing T-nut schematic diagram；
Fig. 2 is the T-nut top view of the utility model；
Fig. 3 is the T-nut side view of the utility model；
Fig. 4 is the T-nut scheme of installation of the utility model；
Fig. 5 is the A direction view of Fig. 4.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but the utility model patent and unlimited
In this example.
A kind of T-nut of the utility model, shape are diamond shape, and two sides are equipped with step, and step is equipped with screw hole 2.Institute
T-nut center is stated equipped with threaded hole, threaded hole is half pin hole 1 of half-thread.
T-nut width W≤0.1 ~ 0.2mm of lathe keyway width of rebate；T-nut length L >=lathe keyway slot opening
Degree.
In T-nut two at step be equipped with screw hole 2, to be fixed in lathe after sinking to stepped hole using screw
In keyway.
Half pin hole 1 of half-thread and the cooperation precision of pin in T-nut are H grades, make it have fixing, the dual function of positioning
Energy.
According to the utility model, specific implementation process mainly have it is several under several steps:
Step 1: being put into as shown in Fig. 2, T-nut width W is flushed with lathe keyway top；
Step 2: as shown in figure 3, T-nut is rotated by a certain angle, the side L being made to be in contact with lathe keyway lower part；
Step 3: being matched by screw with stepped screw hole M at 2, T-nut is fixed in lathe keyway；
Step 4: using screw and T-nut cooperation fixing tooling/part；Or work is positioned with pin and T-nut cooperation
Dress/part；It can also be cooperated with burnished bolt and T-nut, while realize the fixing of part, positioning function.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
