Description

Technical Field

[0001] This utility model relates to the field of instrument processing equipment technology, specifically to a dot correction device. Background Technology

[0002] A thermo-pressure gauge is a device used to monitor the temperature and pressure of a working medium (such as water or other fluids). It can help users monitor and maintain the operating status of equipment and ensure the safe and efficient operation of heating or hot water systems.

[0003] The existing thermobarometers use a riveting process to connect the casing and the measuring rod. However, after the thermobarometer is assembled by riveting, the connection between the measuring rod and the casing often becomes loose, causing the relative position between the two to change. This results in the measuring rod not being able to maintain a perpendicular position to the casing, which in turn affects the normal use and measurement accuracy of the thermobarometer.

[0007] A dotting sleeve, wherein a mounting cavity is provided in the middle of the dotting sleeve for installing dotting pins;

[0008] The case assembly includes a temperature measuring rod and an outer shell, and the base sleeve and the dotting sleeve are arranged coaxially.

[0019] In this invention, a base sleeve is installed on the worktable of the punch press to hold the dial housing assembly, and a dotting sleeve is installed on the pressure plate of the punch press to hold the dotting pin. During the dotting process, the dotting pin is pressed down and the dotting pin is corrected by a concave deformation formed on the riveting part of the dial housing assembly, so that the temperature measuring rod is firmly connected to the outer shell while remaining vertical.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figures 1-5As shown, in one embodiment, a dot correction device includes: a base sleeve 1 and a dot sleeve 3.

[0030] For example, the base sleeve 1 is detachably mounted on the worktable of the punch press to precisely support the watch case assembly 2; while the dotting sleeve 3 is detachably mounted on the pressure plate of the punch press to install the dotting pins 4.

[0031] Specifically, the housing assembly 2 includes a temperature measuring rod 21 and a housing 22. The top of the temperature measuring rod 21 has a cylindrical boss structure, and the bottom of the housing 22 has a corresponding countersunk hole mounting position. The two are riveted together to form an annular riveting part 23 in the contact area by a riveting process.

[0032] Please continue reading. Figures 1-5 In this embodiment, the base sleeve 1 has a receiving cavity 11 in the middle, and the bottom of the watch case assembly 2 is inserted into the receiving cavity 11; while the top of the receiving cavity 11 extends an annular overlapping edge 12, and the middle of the watch case assembly 2 abuts against the overlapping edge 12, which can withstand the pressure during the dot correction process without deformation.

[0033] Specifically, the temperature measuring rod 21 is inserted into the receiving cavity 11, and the receiving cavity 11 precisely limits the temperature measuring rod 21 radially. The riveted part 23 abuts against the overlapping edge 12, and the overlapping edge 12 limits the riveted part 23 circumferentially.

[0034] Correspondingly, the dotting sleeve 3 has a mounting cavity 31 in the middle, and the dotting pin 4 is inserted into the mounting cavity 31, so that the dotting pin 4 can cause the riveting part 23 to undergo controllable plastic deformation, thereby dotting and correcting the riveting part 23 of the watch case assembly 2 in the vertical direction.

[0035] For example, the dotting pin 4 can be made of hard alloy material, with a dotting end with a certain cone angle machined at the front end, so as to form a geometric match with the preset correction point of the riveting part 23 of the temperature measuring rod 21.

[0036] It should be explained in detail that the base sleeve 1 and the dotting sleeve 3 are arranged on the same axis, and the bottom of the dotting pin 4 is parallel to the riveting part 23 of the case assembly 2. This allows the dotting pin 4 to evenly transmit the corrective force to the riveting part 23 each time it is pressed down to make a dotting, avoiding the correction deviation caused by uneven force, and effectively improving the assembly quality and stability of the temperature and pressure gauge.

[0037] Understandably, the base sleeve 1 is installed on the worktable of the punch press to place the watch case assembly 2, and the dotting sleeve 3 is installed on the pressure plate of the punch press to place the dotting pin 4. During the dotting process of the dotting pin 4 pressing down, the concave deformation formed on the riveting part 23 of the watch case assembly 2 is locally plastically deformed and corrected without damaging the base material. This eliminates the gap between the temperature measuring rod 21 and the outer shell 22 while ensuring the vertical positioning accuracy of the temperature measuring rod 21 and the outer shell 22.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
