Description

Technical Field

[0001] The utility model relates to the installation of a gas meter joint, in particular to a special die for riveting a gas meter joint and a meter case. Background Art

[0002] At present, diaphragm gas meters at home and abroad are measured by volume. The inlet and outlet joints of the gas meter bear the function of connecting the pipeline, and are also an important guarantee for the sealing of the pipeline. Most gas meters in the industry use a fixed connection between the shell and the inlet and outlet joints, that is, riveting and welding. Generally, the gas meter case is provided with two joints for air inlet and air outlet. In the prior art, when the joints are installed on the case by riveting, they are installed one by one separately. Due to errors in the case or the joint or the connecting plate inside the case, the upper and lower positions of the two joints cannot be guaranteed to be completely consistent when they are installed. When riveting two joints at one time, it is easy to cause the joint on one side to be riveted in place due to errors, and the joint on the other side may not be riveted in place. Once this happens, the riveting will be loose, prone to leakage, or even falling off, and the defective rate is high. To this end, a special riveting mold for gas meter joints and case is proposed.

[0013] Next, we will further explain the special die for riveting a gas meter joint and a meter case described in the utility model in conjunction with the accompanying drawings.

[0014] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0015] In the present invention, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. should be understood in a broad sense; for example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] See also Figure 1-2As shown in, a special die for riveting a gas meter joint and a meter case, comprising a base 1; characterized in that it also comprises a plurality of columns 2 arranged on the base 1, a pressing plate 3 for mounting the columns 2 on the base 1, an elastic pad 4 sleeved on the columns 2 and located on the pressing plate 3, and a limiting member 5 movably connected to the columns 2 and located on the elastic pad 4, wherein the limiting member 5 comprises a support plate 51 which is separately arranged and movably connected to the columns 2, a plurality of limiting sleeves 52 which are mounted on the support plate 51 and are slidably connected to the columns 2, and a limiting plate 53 for fixing the limiting sleeves 52 on the support plate 51;

[0017] Through the arrangement of the device, when the joints are riveted to the watch case, the riveting of all the joints can be completed at one time, and each joint can be ensured to be riveted in place without the need to rivet one by one, which has high efficiency and high yield.

[0018] In one embodiment, the support plate 51 and the limiting plate 53 on the limiting member 5 are separately provided, and are divided into a limiting member 1 6 and a limiting member 2 61; the separate limiting member 1 6 and the limiting member 2 61 correspond to separate columns 2, and when the joint is pressed downward by a press, the limiting member 1 6 and the limiting member 2 61 can move downward a corresponding distance according to the actual situation when subjected to downward pressure, ensuring that the two separate joints can be completely riveted, avoiding the situation that the joint on one side is riveted into place while the joint on the other side is not riveted into place due to dimensional deviation and the like, so that the limiting member 1 6 and the limiting member 2 61 can automatically adjust the downward movement distance according to the joint and other conditions;

[0019] In one embodiment, the limit member 1 6 and the limit member 2 61 are provided with a dovetail structure for limiting and guiding their positions, and the dovetail structure is a dovetail groove 62 set on the limit member 1 6 and a dovetail block 63 set on the limit member 2 61 and adapted to the dovetail groove 62; through the setting of the dovetail structure, the limit member 1 6 and the limit member 2 61 are connected, and at the same time, their front, back, left and right positions are limited, and the up and down movement of the limit member 1 6 and the limit member 2 61 is guided without interfering with the up and down movement, so that when riveting several joints at the same time, the downward movement distance can be automatically adjusted according to the actual situation, so as to ensure that multiple joints can be riveted simultaneously and completely at one time, thereby improving efficiency and ensuring the yield rate.

[0020] In one embodiment, it also includes a boss 21 arranged on the column 2, and the boss 21 on the column 2 cooperates with the limiting sleeve 52 to form a riveting groove 22; the boss 21 plays a positioning role in positioning the connection plate connected to the joint on the case, ensuring that the connection plate in the case corresponds to the position of the joint, and also plays a limiting role in limiting the position of the joint, ensuring that the joint can be accurately riveted during riveting;

[0021] By setting the riveting groove 22, when a downward extrusion force is applied to the joint, the riveting ring at the lower end of the joint is folded along the riveting groove 22 to complete the riveting.

[0022] In one embodiment, a joint protection cover 7 is also included for protecting the joint of the gas meter. Through the setting of the joint protection cover 7, when the joint is pressed by a press, the joint protection cover 7 is put on the upper end of the joint to prevent the joint from directly contacting the press and causing the upper end of the joint to be pressed and deformed during pressing.

[0023] When the utility model is used, firstly, the connecting plate is installed on the column 2, the hole for installing the joint on the connecting plate corresponds to the boss 21 of the column 2 to complete the definition, then the watch case is installed on the support plate 51 and its position is limited by the limit plate 53, then the joint is placed at the hole for installation in the watch case, and the riveted part of the joint is stuck in the riveting groove 22, then the joint protection cover 7 is put on the joint, and then the press can be started, and the press moves downward to contact the joint protection cover 7 to form a downward extrusion on it, and the extrusion force acts on the joint, and the joint is connected. The head is subjected to a downward force, and the riveting portion of the joint is turned outward along the riveting groove 22 to complete the riveting with the connecting plate, and the portion in contact with the limiting sleeve 52 pushes the limiting sleeve 52 to move downward. During the downward movement of the limiting sleeve 52, the elastic pad 4 is squeezed. After the riveting is completed, the limiting sleeve 52 is pushed upward by the restoring force of the elastic pad 4. During the upward movement of the limiting sleeve 52, the joint is pushed upward and the joint is pushed out of the riveting groove 22, so as to avoid the riveted part of the joint being stuck on the boss 21 or in the riveting groove 22 after riveting, which is convenient for the operator to disassemble and unload.

[0024] The protection scope of the present utility model is not limited to the above embodiments and their variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment all fall within the protection scope of the present utility model.
