[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this utility model is to provide a differential pressure transmitter chamber tooling fixture to solve the problem of inconvenient disassembly and assembly of existing differential pressure transmitter chambers. In particular, it solves the problem that the current device does not use a positioning and locking device on the clamping plate, and the installation fixture cannot effectively limit the displacement of the pressure transmitter when tightening the bolts, resulting in the distortion and deformation of the transmitter chamber. This improves the accuracy of pressure transmitter chamber installation, saves assembly time, and increases assembly efficiency.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides a differential pressure transmitter chamber tooling fixture, such as Figure 1 As shown, the assembly includes: a clamp base 1, multiple ratchet wrenches 2, and at least two clamping plate support columns. The multiple ratchet wrenches 2 are fixedly installed on the upper surface of the clamp base 1, and their layout is consistent with the distribution of the fixing bolt holes of the differential pressure transmitter chamber to be assembled. The clamping plate support columns are erected on the clamp base 1 and located to the side of the multiple ratchet wrenches 2. A positioning clamping plate 3 is provided on the top of the clamping plate support column. The shape of the positioning clamping plate 3 is constructed to be able to be embedded in the cavity at the bottom of the differential pressure transmitter chamber. By matching the layout of the ratchet wrenches 2 with the distribution of the bolt holes in the chamber, combined with the design of the positioning clamping plate 3 being embedded in the cavity at the bottom of the chamber, the differential pressure transmitter chamber can be quickly positioned and accurately assembled, effectively improving assembly efficiency and connection stability.

[0027] In a preferred embodiment, there are four ratchet wrenches 2 arranged in a rectangular array. The four ratchet wrenches 2 arranged in a rectangular array can evenly distribute the tightening force, avoid deformation or damage caused by uneven local force on the chamber, and improve the ease of operation for simultaneous tightening of multiple bolts.

[0028] In a preferred embodiment, the ratchet wrench 2 is fixed to the clamp base 1 by welding or bolting. Welding ensures the structural rigidity of the ratchet wrench 2 and the base, while bolting facilitates the disassembly and replacement of the wrench. Both fixing methods take into account structural stability and maintenance flexibility.

[0029] In a preferred embodiment, the contour of the positioning clamp 3 is adapted to the contour of the bottom cavity of the differential pressure transmitter chamber. The adaptation design of the positioning clamp 3 and the bottom cavity of the chamber can limit the lateral displacement of the chamber during the assembly process, and further improve the coaxiality and positional accuracy of the chamber installation.

[0030] In a preferred embodiment, the clamp support column and the clamp base 1 are integrally formed or connected in a detachable manner. The integrally formed structure enhances the overall strength of the support column and the base, while the detachable connection facilitates the disassembly, transportation, and modular replacement of the clamp, adapting to the needs of different production scenarios.

[0031] In a preferred embodiment, the positioning clamp 3 is made of high-strength plastic or aluminum alloy. The high-strength plastic or aluminum alloy material reduces weight while ensuring the structural strength of the positioning clamp 3, reduces wear on the surface of the chamber, and has good corrosion resistance and service life.

[0032] In a preferred embodiment, the fixture base 1 is provided with a plurality of fixing holes 4 for fixing the fixture base 1 to the workbench with bolts. The fixture base 1 is rigidly connected to the workbench through the fixing holes 4, which can effectively suppress fixture shaking during the assembly process and improve operational safety and dimensional accuracy and stability of the chamber assembly.

[0033] The following is the method of using the differential pressure transmitter chamber tooling fixture provided by this utility model.

[0034] First, the fixture base 1 is securely fixed to the workbench with bolts through the multiple fixing holes 4 on it, ensuring that the fixture will not shake during the subsequent assembly process, thereby ensuring the dimensional accuracy and stability of the assembly.

[0035] Next, place the differential pressure transmitter chamber to be assembled in a suitable position, aligning the cavity at the bottom of the chamber with the positioning clamp 3 at the top of the clamp support column. Slowly lower the chamber, allowing the positioning clamp 3 to embed into the cavity at the bottom of the chamber. Because the contour of the positioning clamp 3 matches the contour of the cavity at the bottom of the differential pressure transmitter chamber, this operation can precisely limit the lateral displacement of the chamber during assembly, further improving the coaxiality and positional accuracy of the chamber installation.

[0036] Next, observe the positions of the multiple ratchet wrenches 2, which are fixedly mounted on the upper surface of the fixture base 1, and their layout corresponds to the distribution of the fixing bolt holes of the differential pressure transmitter chamber to be assembled. Pass the corresponding bolts through the fixing bolt holes of the chamber and place them on the ratchet wrenches 2.

[0037] Next, the bolts are tightened using ratchet wrenches 2. Since there are four ratchet wrenches 2 arranged in a rectangular array, the tightening force is evenly distributed, preventing deformation or damage caused by uneven localized force when tightening the bolts. Simultaneously, the four ratchet wrenches 2 allow for simultaneous tightening of multiple bolts, improving operational convenience. During the tightening process, the ratchet wrenches 2 can be fixed to the clamp base 1 by welding or bolting, depending on the actual needs. Welding ensures the structural rigidity of the ratchet wrench 2 and the base, making the tightening operation more stable; bolting facilitates easy disassembly and replacement of the wrench when needed.

[0038] Throughout the assembly process, depending on the specific production requirements, the clamping support column and fixture base 1 can be connected either as a single, integral structure or in a detachable manner. The integral structure enhances the overall strength of the support column and base, ensuring stability during assembly; a detachable connection facilitates the disassembly, transportation, and modular replacement of the fixture.

[0039] Finally, after tightening all the bolts, check the installation of the differential pressure transmitter chamber again to confirm that its position is accurate and the connection is stable. This completes the assembly process of the differential pressure transmitter chamber using this tooling fixture.

[0040] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
