Abstract
The invention provides an mounting mechanism for a holding furnace thermocouple of a low-pressure casting machine. The mounting mechanism comprises a protective tube and a flange, one end of the protective tube is sealed to the flange, the flange is provided with a thermocouple installing hole, a thermocouple fixing hole is disposed in the protective tube, and the installing hole is in communication with the fixing hole. A thermocouple is fixed in the thermocouple installing hole and stretches into the thermocouple fixing hole when the mounting mechanism is used. The mounting mechanism is simple in structure, and can be very conveniently used for mounting and dismounting a thermocouple, the thermocouple protective tube is sealed to the flange, the sealing can be ensured to prevent hot gases entering into the thermocouple protective tube, the thermocouple is not easy to corrode, the service life of the thermocouple is greatly prolonged, and the damage rate of the thermocouple can be reduced. Hot gases cannot spill out from gaps because no gap existing between the protective tube and the flange, the temperature of an aluminum liquid in a holding furnace can be ensured.
Description
Technical field
The invention belongs to casting technology field, particularly a kind of installing mechanism of low pressure casting machine holding furnace thermocouple.
Background technology
Low pressure casting machine holding furnace usually will arrange thermocouple and carry out temperature detection; thermocouple is arranged on body of heater by ring flange; rock in body of heater to protect thermocouple; need to install protection tube additional position thermocouple and protect; after protecting tube is installed; and do not fix between ring flange, during the work of holding furnace inner inflatable, high temperature hot gas can be overflowed from the gap between pillar and ring flange.And high temperature hot gas directly contacts with thermocouple, thermocouple can be caused to corrode and accelerate, in production process, frequent shutdown changes thermocouple, and the unit efficiency of product is reduced greatly.
Summary of the invention
The deficiencies in the prior art in view of the above, the object of the present invention is to provide a kind of installing mechanism of low pressure casting machine holding furnace thermocouple, prevent thermocouple from being damaged by hot gas.
For achieving the above object and other relevant objects, technical solution of the present invention is as follows:
A kind of installing mechanism of low pressure casting machine holding furnace thermocouple; comprise protection tube and ring flange; described protection tube one end is connected with flangeseal; described ring flange offers thermocouple mounting hole; be provided with thermocouple fixing hole in described protection tube, described installing hole communicates with fixing hole, during use; described thermocouple is fixed in thermocouple mounting hole, and stretches in thermocouple fixing hole.
As preferably: described protection tube one end is provided with the externally threaded joint of band, and described ring flange offers the threaded connection hole coordinated with joint, described protection tube is connected with threaded connection hole by joint with ring flange.
As preferably: described ring flange central authorities have a boss, and described boss offers tapped shoulder hole vertically, and the hole that wherein internal diameter is less is thermocouple mounting hole, and the hole that internal diameter is larger is threaded connection hole.
As preferably: the screw thread of described threaded connection hole is 55 ° of internal threads made in Great Britain.
As preferably: described joint screw thread is the external screw thread made in Great Britain of 55 °.
As preferably: described boss and protection tube lay respectively at the both sides of ring flange.
As mentioned above; the invention has the beneficial effects as follows: structure is simple; mount and dismount very convenient; protecting tube is connected with flangeseal; ensure its sealing, make hot gas cannot enter protecting tube inside, thermocouple element is just not easy corrosion; service life increases greatly, reduces the damage frequency of thermocouple.Because of seamless between pillar and ring flange, therefore hot gas again cannot overflow from gap, ensure that the aluminium coolant-temperature gage of holding furnace inside.

Detailed description of the invention
By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present invention and effect easily.
As shown in Figure 1; a kind of installing mechanism of low pressure casting machine holding furnace thermocouple; comprise protection tube 2 and ring flange 1; described protection tube 2 one end and ring flange 1 are tightly connected; ring flange 1 offers thermocouple mounting hole 13; thermocouple fixing hole 22 is provided with in protection tube 2; described installing hole communicates with fixing hole; during use; thermocouple is fixed in thermocouple mounting hole 13; and stretching in thermocouple fixing hole 22, ring flange 1 is connected with body of heater with bolt by flange hole 14, and thermocouple and protection tube 2 stretch in body of heater.
Further scheme is, described protection tube 2 one end is provided with the externally threaded joint 21 of band, and ring flange 1 offers the threaded connection hole 12 coordinated with joint 21, described protection tube 2 is connected with threaded connection hole 12 by joint 21 with ring flange 1.
In this example, ring flange 1 central authorities have a boss 11, boss 11 offers tapped shoulder hole vertically, shoulder hole runs through ring flange 1 center, shoulder hole bigger diameter end is near ring flange 1, miner diameter end is away from ring flange 1, the hole that wherein internal diameter is less is thermocouple mounting hole 13, and the hole that internal diameter is larger is threaded connection hole 12.Described boss 11 and protection tube 2 lay respectively at the both sides of ring flange 1.
In order to ensure the sealing property of ring flange 1 and protection tube 2, the screw thread of threaded connection hole 12 described in this example is 55 ° of internal thread G3/4 made in Great Britain ", the screw thread of described joint 21 is the external screw thread G3/4 made in Great Britain of 55 ° that want with threaded connection hole 12 to adapt to "; These 55 ° of inch screw threads more easily seal than 60 ° of metric thread.
After adopting said structure, it is inner that hot gas cannot enter protecting tube 2, and thermocouple element is just not easy corrosion, and service life increases greatly.Because of seamless between pillar and ring flange 1, therefore hot gas again cannot overflow from gap, ensure that the aluminium coolant-temperature gage of holding furnace inside.Thermocouple is changed number of times and is reduced by 97%, improves the unit efficiency of product, reduces production cost.Before improvement, monthly chargeable heat galvanic couple 30.After improvement, monthly chargeable heat galvanic couple 1.Greatly reduce thermocouple break frequency.
Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
