Description

Technical Field

[0001] The utility model relates to the technical field of thermocouple pouring devices, in particular to a workpiece positioning plate for thermocouple pouring. Background Art

[0002] Rapid temperature measurement thermocouple usually refers to a disposable consumable thermocouple used to measure the temperature of molten steel and high-temperature molten metal. Its working principle is based on the thermoelectric effect of metal. It uses the temperature difference generated at both ends of the thermocouple to measure the temperature of molten steel and high-molten metal. It is mainly composed of a temperature measuring coupler head and a large paper tube. The coupler head mainly has positive and negative couple wires welded on the compensation wire. The compensation wire is embedded in the bracket. The bracket is covered with a small paper tube. The couple wires are supported and protected by quartz. A slag-proof cap is installed on the outside. All components are concentrated in the mud head and bonded into a whole with a refractory filler. They cannot be disassembled, so they are disposable.

[0003] However, since the space required for pouring the rapid temperature measuring thermocouple is very small, the processing effect of filling the poured space with the gravity of the pouring material's own flow is not good, and looseness is prone to occur. The workpiece positioning plates used in existing thermocouple pouring can only achieve a supporting function and lack the means to solve the above problems. It can be seen that the existing technology for thermocouple pouring still needs further improvement. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 A workpiece positioning plate for thermocouple casting includes a base 1 and a thermocouple body 2. A positioning frame 3 is arranged on the top of the base 1, and a vibration reset structure and a linear travel module 6 are arranged between the bottom of the positioning frame 3 and the top of the base 1. The output structure of the linear travel module 6 can reciprocate the positioning frame 3 and make the positioning frame 3 vibrate reciprocatingly in cooperation with the vibration reset structure;

[0024] Four vibration reset structures are provided and distributed on the four corners of the positioning frame 3. The reset structure includes a T-shaped rod 4 and a first reset spring 5. The two ends of the T-shaped rod 4 are respectively clamped on the inside of the corresponding corner of the positioning frame 3 and fixedly connected to the surface of the top of the base 1. The two ends of the first reset spring 5 are respectively fixedly connected to the bottom surface of the corresponding corner of the positioning frame 3 and the top surface of the base 1, thereby making the positioning frame 3 reciprocate and vibrate as a whole.

[0025] Two linear motion modules 6 are provided and are respectively provided on both sides of the top of the base 1. The linear motion module 6 is composed of an electric push rod and a fixing frame connected to the surface of the electric push rod housing. The top of the fixing frame is fixedly connected to the inner wall of the top of the base 1. The output end of the linear motion module 6 passes through the top structure of the base 1 and is movably fitted with the bottom surface of the positioning frame 3. The linear motion module 6 serves as the power for lifting and lowering the positioning frame 3. After the linkage vibration reset structure is used in combination, the positioning frame 3 and the thermocouple body 2 clamped and placed inside the positioning frame 3 can be automatically vibrated to optimize the replenishment effect of the filler;

[0026] A plurality of middle-hole tubes 7 are sleeved inside the positioning frame 3, and a clamping rod 8 and an electromagnetic chuck 9 are sleeved inside the plurality of middle-hole tubes 7. One end of the clamping rod 8 is magnetically repelled from the electromagnetic chuck 9 in the open state, and the other end of the clamping rod 8 passes through the middle-hole tube 7 and extends to the outside of the middle-hole tube 7. The clamping rods 8 in two adjacent middle-hole tubes 7 are aligned and formed to form a clamping space, and the positioning frame 3 is placed in the clamping space.

[0027] The clamping rod 8 includes a movable rod 81, a magnet block 82, and a second reset spring 83. One end of the movable rod 81 and the magnet block 82 are both sleeved inside the corresponding middle hole tube 7, and the end of the movable rod 81 is fixedly connected to the middle of the magnet block 82. The other end of the movable rod 81 passes through the side wall of the corresponding middle hole tube 7 and extends to the outside of the corresponding middle hole tube 7. The two clamping rods 8 in relative positions can automatically clamp and limit the thermocouple body 2 to be processed, ensuring the stability of the thermocouple body 2 during the pouring process. The two ends of the second reset spring 83 are respectively fixedly connected to the surface of the magnet block 82 and the inner wall of the corresponding middle hole tube 7, providing power for the movement and reset of the movable rod 81 and the magnet block 82. The end of the other end of the movable rod 81 is a curved surface structure that fits the surface of the thermocouple body 2, thereby improving the effect of the clamping connection.

[0028] The surfaces of several middle-hole tubes 7 are provided with clearance grooves 10, and the clearance grooves 10 on the surfaces of two adjacent middle-hole tubes 7 are aligned to form a positioning platform, providing position guidance for the operator to arrange and place multiple thermocouple bodies 2. The front and rear ends of the positioning frame 3 are provided with clearance holes that penetrate the space of the corresponding middle-hole tubes 7, and the clearance holes serve as clearance spaces to provide clearance space for the wires electrically connected to the electromagnetic suction cup 9, facilitating subsequent installation and disassembly.

[0029] Working principle: When in use, the thermocouple body 2 is placed between the two middle-hole tubes 7, and the clamping rods 8 on the surfaces of the two middle-hole tubes 7 are relatively formed into a position platform to provide position traction for the thermocouple body 2. After the thermocouple body 2 is placed stably, the corresponding electromagnetic suction cups 9 inside the two middle-hole tubes 7 are started, and then the electromagnetic suction cups 9 are turned on to generate magnetic force. At the same time, the electromagnetic suction cups 9 output repulsive magnetic force to the corresponding magnet block 82, so that the magnet block 82 drives the corresponding movable rod 81 to move automatically, thereby making the two relative movable rods 81 automatically clamp the thermocouple body 2;

[0030] After the thermocouple body 2 is clamped and stabilized, the existing pouring equipment automatically pours the top of the thermocouple body 2. At the same time, the electric push rod inside the linear travel module 6 is reciprocatedly opened and closed, so that the output end of the electric push rod reciprocates the positioning frame 3, so that the positioning frame 3 reciprocates and vibrates under the guidance of the T-bar 4 and the elastic limit of the first return spring 5, to ensure that the casting material is filled tightly;

[0031] After the pouring is completed, the electromagnetic chuck 9 is closed, and the two correspondingly clamped movable rods 81 and the magnet block 82 are automatically moved and reset under the action of the corresponding second reset spring 83, and the thermocouple body 2 is taken out.
