Description
Technical field:
The utility model relates to ionic nitriding equipment technical fields more particularly to a kind of ion nitriding furnace thermocouple temperature measurement to fill
It sets.
Background technique:
When ion nitriding furnace carries out nitrogen treatment to metal works, thermocouple needs to measure workpiece temperature.In the prior art
Thermocouple is mounted in cathode site, and thermocouple is inserted directly into workpiece, measures workpiece temperature.Each blow-on, thermocouple all can be with
Workpiece nitrogenize together, the problem is that, after repeatedly nitrogenizing, thermocouple is hardened to become fragile thermocouple, it is easy to fracture.Subtract
The physical life for having lacked thermocouple, increases production cost.
Therefore there is an urgent need to a kind of technical solutions to solve the above problems in existing technology.
Utility model content:
The purpose of this utility model be in view of the drawbacks of the prior art, provide a kind of structure it is simple, it is easy for installation, measurement essence
Really, ion nitriding furnace thermocouple temperature measuring apparatus with long service life.
The utility model is achieved by the following technical solution: a kind of ion nitriding furnace thermocouple temperature measuring apparatus, including
Thermocouple, glass tube and screw rod, the screw rod axial centre offer deep hole, and the glass tube grafting enters in the deep hole, institute
It states thermocouple one end to be fixed in glass tube, the other end is extended to outside glass tube and connect with the anode of ionic nitriding furnace body.
It is connect for the ease of screw rod with workpiece, screw thread is offered outside the screw rod.
Preferably, the deep hole depth of the screw rod is 25mm.
In order to guarantee service life, the glass tube is quartz glass tube.
It loosens in order to prevent, the glass tube and screw rod are interference fitted.
Preferably, the wall thickness of glass tube is 1mm.
The beneficial effects of the utility model are: the installation of TC of the ion nitriding furnace thermocouple temperature measuring apparatus is in nitriding furnace
Anode above, by thermocouple be inserted into quartz glass tube in, quartz glass tube be inserted into screw rod in, screw rod is mounted on workpiece,
Thermocouple and workpiece are connected, realize that structure is simple, and easy for installation, service life is longer to the accurate thermometric of workpiece.

In figure: 1. thermocouples, 2. glass tubes, 3. screw rods, 4. deep holes.
Specific embodiment:
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be understood by those skilled in the art with feature, to make apparent specific boundary to the protection scope of the utility model
It is fixed.Direction term that the utility model is previously mentioned, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom" etc.,
It is only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the utility model, rather than to
Limit the utility model.
As shown in Figure 1-3, a kind of ion nitriding furnace thermocouple temperature measuring apparatus, including thermocouple 1, glass tube 2 and screw rod 3,
3 axial centre of screw rod offers deep hole 4, and 2 grafting of glass tube enters in the deep hole 4,1 one end grafting of thermocouple
Enter in glass tube 2, the other end is extended to outside glass tube 2 and connect with the anode of ionic nitriding furnace body.
As shown in figure 3, the glass tube 2 is quartz glass tube, glass tube 2 and screw rod 3 are interference fitted, the length of glass tube 2
Degree is preferably 45mm, and wall thickness is preferably 1mm.
The screw rod 3 of the utility model can be smooth shaft shape, screw thread can also be opened up outside screw rod 3, as shown in figure 4, described
The length of screw rod 3 is preferably 30mm, and 4 depth of deep hole is preferably 25mm.
The thermocouple 1 of the utility model is mounted on anode position, is inserted into quartz glass tube 2, and glass tube 2 is inserted into spiral shell
In the deep hole 4 of bar 3, screw rod 3 is mounted on workpiece, avoids the short circuit of anode and cathode in this way, while avoiding thermocouple 1 through excessive
Secondary ion nitrogenizes service life decline, and structure is simple, easy to use, is easily installed and dismantles and improve thermocouple 1
Physical life.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.
