Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of gas meter production equipment, specifically relates to an adjusting module for metering shell preloading. BACKGROUND

[0002] The riveting process of the metering shell is one of the important links of gas meter assembly. Since the metering shell and the core body are produced by different production equipment, there are differences in the control of precision and the actual product precision. If the direct riveting method is used, it is easy to cause the riveting teeth to hinder the buckling of the two when the metering shell and the core body are riveted, which affects the production efficiency. At the same time, this also requires higher action precision of the mechanical hand for buckling operation, increases the equipment cost and implementation difficulty. Therefore, the applicant early proposed the method of expanding the teeth of the metering shell before riveting, such as the patent with the patent number "CN113927277B" and the name "membrane type gas meter metering shell pressure sealing system". In the patent, the profiled tool is mainly used for expanding the teeth of the metering shell. The applicant found in continuous research that the outer side of the edge of the metering shell is not blocked during the tooth expansion process. Therefore, under the action of the inclined surface, the actual expansion consistency of the metering shell riveting teeth is poor, which affects the subsequent automatic riveting process. SUMMARY

[0003] Therefore, the utility model provides an adjusting module for metering shell preloading to solve the problem of poor riveting tooth expansion quality of the metering shell in the prior art, which is not conducive to subsequent assembly.

[0004] The technical scheme is as follows:

[0005] An adjusting module for metering shell preloading, the key point of which is that the adjusting module comprises a metering shell turnover structure and a metering shell tooth expansion structure. The turnover structure comprises a turnover seat, a turnover cylinder, and a profiled tool corresponding to the turnover seat. The profiled tool is provided with a profiled jacking cylinder. The turnover cylinder controls the turnover of the turnover seat. The metering shell on the turnover seat with the concave cavity upward is buckled to the profiled tool. The key point of the tooth expansion structure is that the tooth expansion structure comprises a tooth expansion seat corresponding to the profiled tool and a tooth expansion cylinder for driving the horizontal sliding of the tooth expansion seat. The tooth expansion seat can slide to the upper side of the profiled tool under the driving of the tooth expansion cylinder. The tooth expansion seat has a cavity with an open downward, and the inner contour of the cavity is adapted to the outer part of the metering shell.

[0006] When the profiled jacking cylinder lifts the profiled tool, the lateral contour of the metering shell is limited by the tooth expansion seat, and the tooth expansion seat is in a relatively fixed state. Therefore, the expansion effect of the metering shell riveting teeth is more stable and uniform.

[0007] As preferred: further comprising an adjustment platform, the metering shell turning structure and the metering shell tooth expanding structure are arranged on the adjustment platform. With the above scheme, modular installation is facilitated, and different installation environments are adapted.

[0008] As preferred: the adjustment platform is provided with a tooth expanding guide rail in sliding fit with the tooth expanding seat. With the above scheme, the sliding stability and position accuracy of the tooth expanding seat are ensured.

[0009] As preferred: an intermediate plate is comprised, the intermediate plate is provided with an adjustment guide rail arranged along the length direction thereof, the adjustment platform is in sliding fit with the adjustment guide rail, and the intermediate plate is provided with a driver for driving the adjustment platform to slide along the adjustment guide rail. With the above scheme, the position of the adjustment module can be quickly and conveniently adjusted, and the disassembly and assembly efficiency is improved.

[0010] As preferred: the intermediate plate is provided with an avoiding groove corresponding to the profiled jacking cylinder. With the above scheme, the profiled jacking cylinder can be partially sunk below the intermediate plate, so that the height space occupied by the installation can be relatively saved, and the whole is more compact.

[0011] As preferred: the profiled tool has a counterbore at least at two opposite corners. The profiled tool can be better matched with the grabbing and placing mechanism, and the consistency of the grabbing posture of the metering shell is improved.
