Embodiment 1

[0019] Embodiment 1, a thermocouple precise positioning device, including a thermocouple body 1, a socket 2 is sleeved on the thermocouple body 1, and a sleeve 3 is sleeved on the left end of the sleeve 2, and the upper end of the sleeve 3 is fixedly welded There is a fixed block 4, the inside of the fixed block 4 is equipped with a screw rod 5 through a bearing, and the center position of the screw rod 5 is fixedly sleeved with a knob 6, the upper end of the knob 6 is in the gap 7, and the gap 7 is opened in the fixed block 4 At the center position of the upper end, the two ends of the screw rod 5 are symmetrically sleeved with a screw nut 8, and the screw nut 8 is fixedly installed at the opening of the sleeve rod 9, and the sleeve rod 9 is symmetrically sleeved at both ends of the screw rod 5, and the two sets of sleeve rods The outer ends of 9 pass through the front and rear ends of the fixed block 4 respectively, and the outer ends of the sleeve rod 9 are fixedly welded wi...

Embodiment 2

[0020] Embodiment 2, the outside of the socket 2 is provided with external threads, the inside of the block 3 is provided with internal threads matching the external threads of the socket 2, the socket 2 is set as a cone, and the inside of the block 3 is provided with a The outer size of the sleeve 2 matches the conical groove, and the sleeve 2 is equidistantly surrounded by a V-shaped opening. This structure enables the sleeve 2 to be inserted into the sleeve block 3 through thread rotation, and inserted into the sleeve block with the conical head The deeper the depth inside 3 is, the conical head of the sleeve 2 will gradually shrink to change the inner diameter of the sleeve 2, so that the thermocouple body 1 can be clamped and fixed by the shrinkage of the sleeve 2, so that the entire positioning and fixing device can Installed on the thermocouple body 1.

Embodiment 3

[0021] Embodiment 3, the surfaces of both ends of the screw rod 5 are symmetrically provided with threads that match the screw nut 8, and the sleeve rod 9 is provided with a chute matching the outer size of the end of the screw rod 5, and the sleeve rod 9 is inserted into the fixed block One end in the 4 is set to a square shape, and the inside of the fixed block 4 is provided with a chute that matches the size of the square end of the sleeve rod 9. This structure makes the two sets of wires sleeved on the screw rod 5 rotate when the screw rod 5 rotates. Female 8 can cooperate with the screw thread on screw mandrel 5 to move oppositely, and because one end of sleeve rod 9 inserted in fixed block 4 is square, so sleeve rod 9 can't rotate in fixed block 4, causes screw nut 8 to be unable to move on the wire. Rotate on the rod 5, so that when the screw rod 5 rotates, it will not drive the screw nut 8 to rotate, but it will make the screw nut 8 drive the sleeve rod 9 along the scre...

Abstract

The invention discloses a thermocouple accurate positioning device. The device comprising a thermocouple body, the thermocouple body is sleeved with a plug bush. The left end of the plug bush is sleeved with a sleeve block. A fixed block is fixedly welded at the upper end of the sleeve block; a screw rod is mounted in the fixed block through a bearing; a knob fixedly sleeves the central position of the screw rod; the upper end of the rotary knob is located in the notch, the notch is formed in the center of the upper end of the fixing block, the two ends of the lead screw are symmetrically sleeved with nuts, the nuts are fixedly installed at openings of sleeve rods, the two ends of the lead screw are symmetrically sleeved with the sleeve rods, and the outer ends of the two sets of sleeve rods penetrate through the front end and the rear end of the fixing block correspondingly. By arranging the plug bush and the sleeve block, the plug bush and the sleeve block can clamp the thermocouplebody in a threaded rotation connection mode, so that the thermocouple body is fixed, and the thermocouple is convenient to mount and dismount.

Description

technical field [0001] The invention relates to the technical field of thermocouple precise positioning devices, in particular to a thermocouple precise positioning device. Background technique [0002] A thermocouple is a temperature-sensing element and an energy converter that converts heat energy into electrical energy. When installing a thermocouple, a positioning installation device is required, such as the patent No.: CN 207585790 U, a publicized Fixture for precise adjustment of thermocouple height. The device includes a locator, a protective sleeve, and a standard scale is set on the protective sleeve; the locator includes a hollow threaded tube and a support ferrule, and the protective sleeve passes through the hollow threaded tube. This patent can precisely adjust the thermocouple to extend into the furnace cavity Or the height inside the crucible, reasonable structure, easy to use, can quickly and accurately adjust any required height, effectively solving the pro...
