Description

Technical Field

[0001] The utility model relates to the field of automobile sheet metal spraying, in particular to a device for measuring flame core temperature. Background Art

[0002] Automotive sheet metal parts are limited by the injection molding process, and there will be inconsistencies in the thickness of the workpiece surface, resulting in differences in the surface stress of automotive parts, which are not suitable for direct painting. Therefore, before the painting process, the surface of the automotive parts is generally homogenized by a flame gun, that is, the high temperature of the flame gun (the flame core temperature is 900°C) is used to burn the surface of the workpiece, and the surface of the workpiece is reshaped by 1mm-2mm, so that the surface of the workpiece is homogenized, thereby solving the painting problem caused by the difference in surface stress of automotive parts.

[0003] During the flame treatment process, the temperature of the flame gun must be strictly controlled. If the temperature is too high, the workpiece may be burned, and if the temperature is too low, the surface of the workpiece cannot be homogenized. However, currently flame guns are standardized processing equipment and cannot monitor the temperature of the flame core when burning the workpiece, which leads to poor homogenization of the workpiece surface.

[0004] Therefore, those skilled in the art are committed to developing a device for measuring the flame core temperature to solve the problem that the temperature of the flame core when burning the workpiece cannot be detected, which leads to poor surface homogenization effect of the workpiece. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a device for measuring the temperature of a flame core, so as to solve the problem that the temperature cannot be detected when a flame gun burns the surface of a workpiece.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the base frame includes two supporting legs, and the top ends of the two supporting legs are connected via a transverse mounting seat.

[0010] The beneficial effect of adopting the above further solution is that the support legs can provide a certain height from the ground for the transverse mounting seat, ensuring that the flame gun can be laterally close to the transverse mounting seat.

[0011] Furthermore, a positioning protrusion is provided on the side of the transverse mounting seat.

[0012] The beneficial effect of adopting the above further solution is that the side of the protrusion is in firm contact with the side of the flame gun, so as to limit the position of the flame gun, which is convenient for the staff to calibrate the relative position of the flame gun and the detection device, thereby ensuring the accuracy of the detection.

[0013] Furthermore, a probe fixing protrusion is provided on the front end surface of the slider, and a probe reinforcement mounting hole is opened on the probe fixing protrusion corresponding to the probe mounting hole; the shapes of the probe mounting hole and the probe reinforcement mounting hole are adapted to the shape of the temperature sensor probe, and a first threaded locking hole is opened on the side of the probe fixing protrusion, and the first threaded locking hole is connected to the probe reinforcement mounting hole.

[0014] The beneficial effect of adopting the above further solution is that the probe fixing protrusion can further fix the temperature sensor probe to ensure that the temperature sensor probe has sufficient lateral length to extend to the position of the flame core for measurement, thereby ensuring the accuracy of the detected temperature.

[0015] Furthermore, a second thread locking hole is provided on the rear side of the slider; the second thread locking hole is provided on the left side, right side or rear side of the slider.

[0016] The beneficial effect of adopting the above further scheme is that the positions of the slider and the slide rod are fixed by screws, so that the position of the temperature sensor probe can be manually adjusted according to the height of the flame core, and the position of the temperature sensor probe can be fixed, thereby improving the versatility of the utility model.

[0017] Furthermore, there are two scales, which are respectively arranged at two ends of the transverse mounting seat; and the sliding rod is located in the middle of the two scales.

[0018] The beneficial effect of adopting the above further solution is that it is easy to perform height positioning on the slider.

[0019] The beneficial effects of the utility model are as follows: by installing the utility model around the flame gun, when it is necessary to detect the flame core temperature of the flame gun, first move the flame gun to the side of the horizontal mounting seat, make the upper surface of the flame nozzle of the flame gun flush with the upper surface of the horizontal mounting seat, refer to the position of the scale next to it, move the slider, adjust the position height of the temperature sensor probe to be consistent with the position height of the flame core, and then turn on the control switch of the flame gun, so that the temperature of the flame core can be accurately measured, ensuring that the operating temperature of the flame gun is not too high or too low, realizing the detection of the surface temperature of the workpiece burned by the flame core, and ensuring the quality and effect of the flame gun in homogenizing the surface of the workpiece.

[0029] like Figures 1 to 3 As shown, a device for measuring flame core temperature comprises a base frame 1, on which a temperature detection component 2 is provided;

[0030] The temperature detection assembly 2 includes a transverse mounting seat 3, and a scale 4 and a slide rod 5 are vertically provided on the upper surface of the transverse mounting seat 3. Specifically, there are two scales 4, which are respectively arranged at the two ends of the transverse mounting seat 3; the slide rod 5 is located in the middle of the two scales 4. It is convenient to accurately measure the height of the slider relative to the transverse mounting seat 3 when adjusting the height of the slider. A slider 6 is provided on the outer cover of the slide rod 5, and a probe mounting hole 7 is provided in the center of the slider 6; the probe mounting hole 7 is used to install a temperature sensor probe 9; a clearance groove 8 is provided at the position of the slide rod 5 corresponding to the probe mounting hole 7; the clearance groove 8 is provided along the vertical direction of the slide rod 5.

[0031] When measuring the flame core temperature through the device, the height of the flame core is first determined. For example, when the flame core height is determined to be 150 mm, the slider is moved, and the position of the temperature sensor probe is adjusted to a height of 150 mm with reference to the scales 4 on both sides, and the slider is fixed to the slide rod with screws.
