[0002] An ionization chamber is a device commonly used in chemical analysis or substance detection, used to ionize samples for analysis. Within the chamber, the sample is exposed to ionizing radiation, forming ions. These ions are then separated and detected based on their mass-to-charge ratio under the influence of an applied electric or magnetic field. This process enables analysts to conduct in-depth research and analysis of the sample's composition, structure, and properties. Ionization chambers play a key role in mass spectrometry instruments, such as proton mass spectrometers and gas chromatography-mass spectrometry. Ionization chamber technology is widely used in fields such as chemistry, biology, and environmental science to determine the properties and composition of substances, as well as for quantitative analysis and structural studies.

[0038] Example:

[0039] This embodiment provides a tool for welding a special-shaped ionization chamber, which is used to solve the technical problem in the prior art that special-shaped ionization chambers are prone to deviation during welding. The tool for welding a special-shaped ionization chamber includes a base 1, a placement component, a limit component, and a support member 4, wherein:

[0040] The base 1 is provided with an external connection portion, which is used to connect the base 1 to an external object.

[0041] The placement component can be detachably mounted on the base 1. The placement component is used to place the workpiece to be welded and limit the movement of the workpiece to be welded in the first direction and the rotation in the circumferential direction. It should be noted that the first direction is the radial direction of the workpiece to be welded. Specifically, the workpiece to be welded, that is, the special-shaped ionization chamber 6 to be welded includes a cylinder 61 and three cavity plates 62. The cylinder 61 has a through hole arranged along the axial direction. A plurality of convex teeth are provided on the three cavity plates 62, and the plurality of convex teeth on the same cavity plate 62 are evenly distributed along the circumferential direction of the cavity plate 62. The three cavity plates 62 are respectively installed at both ends and the middle of the cylinder 61, and the convex teeth of the three cavity plates 62 extend out of the cylinder 61. The three cavity plates 62 are respectively an upper cavity plate, a middle cavity plate and a lower cavity plate.

[0042] The limiting assembly can be detachably mounted on the base 1, and the limiting assembly is located on the outside of the placement assembly. The limiting assembly is used to limit the movement of the workpiece to be welded in the second direction. The first direction and the second direction are arranged perpendicular to each other. The second direction is the axial direction of the workpiece to be welded. In this way, the movement of the workpiece to be welded in the second direction is limited by the setting of the limiting assembly.

[0043] The support member 4 is installed on the base 1. The support member 4 is used to support the workpiece to be welded. Specifically, the support member 4 includes a base plate and a support rod. The base plate is installed on the base 1 by bolts, one end of the support rod is installed on the base plate, and the other end of the support rod is supported on the convex teeth of the middle cavity plate. In this way, through the setting of the support member 4, support is provided for the workpiece to be welded, deformation of the workpiece is prevented, and the probability of displacement of the workpiece is reduced.

[0044] Through the above structure, when using the tooling for welding the special-shaped ionization chamber provided by the present invention, the convex teeth on the cavity plates 62 at both ends of the special-shaped ionization chamber 6 are first placed in the placement component to prevent the special-shaped ionization chamber 6 from being displaced in the first direction and the special-shaped ionization chamber 6 from rotating in the circumferential direction, and the side walls of the cavity plates 62 at both ends of the special-shaped ionization chamber 6 are connected to the limiting component located outside the placement component, that is, the special-shaped ionization chamber 6 is clamped in the limiting component, thereby preventing the special-shaped ionization chamber 6 from being displaced in the second direction, and then Finally, the cavity plate 62 located in the middle of the special-shaped ionization cavity 6 is placed on the support member 4. In this way, through the setting of the support member 4, a supporting force is provided for the cavity plate 62 located in the middle of the special-shaped ionization cavity 6 during the welding process, reducing the probability of deformation of the workpiece, thereby reducing the probability of displacement of the workpiece during the welding process. Therefore, through the cooperation of the placement component, the limit component and the support member 4, the tooling for welding the special-shaped ionization cavity provided by the present invention can clamp the special-shaped ionization cavity 6 more firmly, reducing the probability of its displacement during the welding process.

[0045] An optional implementation of this embodiment is as follows: the placement component includes two placement blocks 2, both of which are detachably mounted on the base 1 and spaced apart along the second direction, and the two placement blocks 2 are located on both sides of the support 4, and the two placement blocks 2 are used to place the two ends of the workpiece, that is, the distance between the two placement blocks 2 in the second direction is equal to the length of the special-shaped ionization chamber 6 in the second direction, and the convex teeth on the upper cavity plate and the lower cavity plate are respectively placed on the two placement blocks 2. By setting the two placement blocks 2, the two ends of the special-shaped ionization chamber 6 are placed, which makes it easier to weld the three cavity plates 62 to the cylinder 61.

[0046] Optionally, the placement block 2 includes a horizontal rod 21 and a first vertical rod 22, wherein:

[0047] The crossbar 21 is detachably mounted on the base 1 , and the length direction of the crossbar 21 is arranged along the first direction.

[0048] There are two first vertical rods 22, and one end of the two first vertical rods 22 is fixedly mounted on the two ends of the cross rod 21, and the two first vertical rods 22 are arranged along the third direction, and the first direction, the second direction and the third direction are arranged perpendicular to each other in pairs. In this way, when the cavity plate 62 is placed, the cavity plate 62 is located between the two first vertical rods 22, and the two protruding teeth on the same cavity plate 62 are respectively overlapped with one end of the two first vertical rods 22 on the same placement block away from the cross rod 21, and the side wall of the cavity plate is in contact with the two first vertical rods. In this way, not only can the special-shaped ionization chamber 6 be supported on the bottom plate, but also the cavity plate 62 can be prevented from moving in the first direction and rotating along the axial direction.

[0049] Optionally, the crossbar 21 is mounted on the base 1 by screws. In this way, the crossbar 21 mounted by screws is more convenient for disassembling and assembling the placement block 2.

[0050] An optional implementation of this embodiment is as follows: the limiting assembly includes two groups of limiting members, both groups of limiting members are installed on the base 1 and are respectively located on the opposite side of the two placement blocks 2, that is, the two placement blocks 2 are located between the two limiting members, the two limiting members are arranged in a one-to-one correspondence with the two placement blocks 2, and the length of the limiting members in the third direction is greater than the length of the placement blocks 2 in the third direction. Through the setting of the two groups of limiting members, after the upper cavity plate and the lower cavity plate are placed on the two placement blocks 2, the end of the upper cavity plate away from the lower cavity plate is abutted against the corresponding limiting member, and the end of the lower cavity plate away from the upper cavity plate is abutted against the corresponding limiting member. In this way, the special-shaped ionization chamber 6 to be welded is clamped between the two limiting assemblies to prevent the special-shaped ionization chamber 6 from moving in the second direction.

[0051] Optionally, the limiting member includes two second vertical rods 3, and the two second vertical rods 3 are respectively installed on the side of the two first vertical rods 22 away from the support member 4. It should be noted that the second vertical rod 3 and the corresponding first vertical rod 22 can be connected together by welding, hot melting or bonding, and of course, can also be integrally formed.

[0052] An optional implementation of this embodiment is as follows: it also includes a clamping hoop 5. In the working state, the clamping hoop 5 is installed outside the special-shaped ionization chamber 6. The clamping hoop 5 is used to clamp the special-shaped ionization chamber 6, thereby reducing the probability of workpiece expansion during welding.

[0053] Optionally, the number of clamping hoops 5 is two. Specifically, in the working state, the two clamping hoops 5 are installed on the cylinder 61 of the special-shaped ionization chamber 6, and the two clamping hoops 5 are respectively located between the three cavity plates 62. The setting of the two clamping hoops 5 further reduces the probability of expansion of the special-shaped ionization chamber 6 during the welding process.

[0054] Optionally, the clamping band 5 includes a clamping portion 51 and a connecting portion, wherein:

[0055] There are two clamping parts 51 , which are symmetrically arranged. The clamping parts 51 are used to clamp the special-shaped ionization chamber 6 .

[0056] Optionally, the clamping portion 51 is arc-shaped. In this way, the arc-shaped clamping portion 51 can better fit the special-shaped ionization cavity 6, so that the force applied to the special-shaped ionization cavity 6 is more uniform.

[0057] The connecting portion is installed on the clamping portion 51, and the connecting portion is used to connect the two clamping portions 51. In this way, when using the tooling for welding the special-shaped ionization chamber provided by the embodiment of the utility model, the two clamping portions 51 are first symmetrically installed on the cylinder 61, and then the two clamping portions 51 are connected together through the connecting portion.

[0058] Optionally, the connecting part includes four connecting blocks 52, and the four connecting blocks 52 are two first connecting blocks and two second connecting blocks. The two first connecting blocks are respectively installed at one end of the two clamping parts 51, and the two first connecting blocks are connected by bolts. The two second connecting blocks are respectively installed at the other end of the two clamping parts 51, and the two second connecting blocks are connected by bolts. In this way, the setting of the two first connecting blocks connected by bolts and the two second connecting blocks connected by bolts facilitates the disassembly and assembly of the clamping part 51.

[0059] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model.
