Description

Technical Field

[0001] This utility model relates to the field of gas cylinder tooling technology, specifically to an interchangeable drilling tooling for gas cylinders. Background Technology

[0002] In the field of gas cylinder manufacturing, the machining accuracy of the lug positioning holes is crucial for the connection between the gas cylinder and the machine base. However, traditional drilling fixtures have certain drawbacks, such as... Figure 4 As shown, existing tooling is generally of a fixed structure. Since a separate drilling tooling set needs to be manufactured for each type of gas cylinder, processing costs increase significantly and the production time is extended. Furthermore, the wide variety of gas cylinders results in a large inventory of drilling tooling, causing chaotic on-site management. Moreover, most tooling cannot be reused after a single use, leading to serious resource waste. Therefore, developing an interchangeable drilling tooling that can improve tooling versatility, reduce costs, and increase efficiency is an urgent problem to be solved. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an interchangeable drilling tool for gas cylinders, solving the problem of low adaptability of existing tooling.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an interchangeable drilling fixture for gas cylinders, including a base, a base plate fixedly installed on the base, a cover plate detachably installed on the base plate through a positioning component, an opening for the gas cylinder to pass through on both the base plate and the cover plate, a pressure cap on the cover plate, a pair of through holes on both sides of the pressure cap and the cover plate, a long bolt passing through the through holes on both sides, and a nut screwed to the bottom of the long bolt.

[0005] Preferably, the positioning component includes a plurality of fixing rods fixedly disposed on the upper wall of the cover plate, the plurality of fixing rods being arranged in a circular array on the cover plate, and a sleeve corresponding to each fixing rod being detachably installed on the lower wall of the pressure cover, the sleeve being fitted onto the fixing rod, and a fixing mechanism being provided between the sleeve and the fixing rod.

[0006] Preferably, the fixing mechanism includes a bracket disposed on the outer wall of the sleeve, a positioning bolt is horizontally screwed onto the bracket, a circular hole is provided on the side wall of the sleeve for the positioning bolt to pass through, and a positioning hole is provided on the side wall of the fixing rod for the positioning bolt to be inserted.

[0007] Preferably, a stud is fixedly provided at the upper end of the sleeve, and a screw hole matching the stud is provided on the lower wall of the cover plate.

[0008] Preferably, the pressure cap has a circular pressure groove.

[0009] Preferably, the positioning bolt is a wing bolt structure.

[0010] Preferably, the gas cylinder has a spherical structure and the lugs that require drilling on both sides can be placed on the cover plate.

[0011] Beneficial effects

[0012] This utility model provides an interchangeable drilling fixture for gas cylinders, which has the following advantages:

[0013] This interchangeable drilling fixture, through the combination of components such as a base, base plate, detachable cover plate, and pressure cap, allows most gas cylinders to use a single set of fixtures. Only the cover plate needs to be replaced to adapt to different gas cylinders. This design greatly improves the versatility of the fixture, reduces the number of fixtures to be manufactured, not only lowers the manufacturing cost of the fixtures but also improves the product delivery cycle and enhances the company's market competitiveness.

[0014] In the positioning assembly, the cooperation between the fixing rod and the sleeve, as well as the connection between the positioning bolt and the positioning hole in the fixing mechanism, can accurately position the cover plate and the pressure cap, ensuring the stability of the gas cylinder position during drilling and improving drilling accuracy. At the same time, the positioning bolt with the wing bolt structure makes it easy for operators to tighten and loosen quickly, improving operating efficiency.

[0015] The circular groove on the cap allows for better contact with the gas cylinder, applying pressure evenly and keeping the cylinder stable during drilling. This prevents cylinder movement from affecting drilling quality. The long bolts and nuts on both sides can adaptively adjust the distance between the cap and the cover plate according to the size of the gas cylinder, meeting the fixing needs of gas cylinders of different sizes and ensuring the reliability and ease of use of the tooling.
