Description

Technical Field

[0001] This invention belongs to the field of instrument manufacturing technology, specifically a welding device for instrument manufacturing. Background Technology

[0002] With the rapid development of the instrument manufacturing industry, welding technology plays a crucial role in instrument production. Welding equipment is used to precisely connect the various components of instruments to ensure their performance and reliability. Existing welding equipment for instrument manufacturing typically employs a fixed clamping device to position the instrument components and performs the welding operation via a welding head. However, existing technology has the following problems; Existing clamping devices typically employ fixed structures, making it difficult to adapt to instrument components of varying thicknesses or diameters, resulting in inaccurate positioning and affecting welding quality. Furthermore, during the welding process, instrument components are prone to slight displacement due to vibration or external forces, which can affect welding accuracy. Therefore, a welding device for instrument manufacturing is proposed. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] Given the following technical problems in the existing technology: existing clamping devices usually adopt a fixed structure, which is difficult to adapt to instrument parts of different thicknesses or diameters, resulting in inaccurate positioning and affecting welding quality; at the same time, during the welding process, the instrument parts are prone to slight displacement due to vibration or external force, which affects the welding accuracy.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a welding device for manufacturing instruments and meters, comprising a base and a positioning seat; The top of the base is fixed to a support plate. A positioning seat is installed on one side of the support plate, and an extension frame is installed at the top of the support plate. A drive gear is hinged to one side of the extension frame, and a motor is installed on the other side of the extension frame. The motor drives the drive gear to rotate. A guide hole is provided on the positioning seat, and a telescopic limit frame is provided on the guide hole. The end of the limit frame that extends into the positioning seat is an inclined part. When multiple limit frames extend into the positioning seat, the inclined part can limit the movement of instrument parts of different thicknesses and diameters.

[0006] As a preferred technical solution for welding equipment used in instrument manufacturing, the base is provided with a guide groove, and a support plate is telescopically mounted on the base above the guide groove. An X-axis motion component is provided in the guide groove to change the position of the support plate, and a support seat is mounted on the support plate.

[0007] As a preferred technical solution for welding equipment used in instrument manufacturing, the positioning seat has a linkage cavity, the side of the limiting frame has teeth, a linkage gear is rotatably connected in the linkage cavity, the linkage gear engages with the limiting frame, a threaded rod is coaxially mounted on the linkage gear, a threaded sleeve is externally threaded on the threaded rod, and a protrusion is installed on the threaded sleeve. When the limiting frame moves in a telescopic motion, the limiting frame causes the linkage gear to rotate through the engagement transmission, the linkage gear drives the threaded rod to rotate together, and the threaded rod drives the threaded sleeve to move in a telescopic motion under the action of the threaded transmission and the protrusion.

[0008] As a preferred technical solution for welding equipment used in instrument manufacturing, the positioning seat is movably equipped with an external gear ring, which meshes with the drive gear for transmission. When the motor rotates, the external gear ring can be driven to rotate through the drive gear.

[0009] As a preferred technical solution for welding equipment used in instrument manufacturing, the inner edge of the external gear ring is provided with an annular groove, and the protrusion is located in the annular groove. When the protrusion moves in extension and retraction, it can move in conjunction with the external gear ring to extend and retract together. When the external gear ring rotates alone, the protrusion will not be affected.

[0010] As a preferred technical solution for welding equipment used in instrument manufacturing, a second linkage gear is hinged in the positioning seat, the second linkage gear meshes with the limit frame, and a worm gear is installed in the middle section of the second linkage gear.

[0011] As a preferred technical solution for welding equipment used in instrument manufacturing, the worm gear is externally engaged with a worm.

[0012] As a preferred technical solution for welding equipment used in instrument manufacturing, the worm gear is coaxially mounted with a third linkage gear, and the positioning seat is rotatably equipped with an internal gear ring. The internal gear ring meshes with the third linkage gear, causing the internal gear ring to rotate. The internal gear ring meshes with the third linkage gear, which in turn links the worm gear. The worm gear meshes with the worm wheel, and the second linkage gear rotates together with the worm wheel at this time. The limiting frame will then extend and retract. When multiple limiting frames extend and retract, they can limit the position of the instrument components.

[0013] As a preferred technical solution for welding equipment used in instrument manufacturing, a support arm is installed on the side of the external gear ring, and a rotating plate is hinged on the support arm to facilitate the adjustment of the position of the welded parts and to facilitate the entry of the instrument parts into the positioning seat.

[0014] As a preferred technical solution for welding equipment used in instrument manufacturing, the rotating plate is equipped with welding components, which are used for welding instruments.

[0015] The beneficial effects of this invention are: 1. This solution, through the limiting frame and its inclined part inside the positioning seat, can adapt to instrument parts of different thicknesses and diameters, achieve precise positioning and firm limiting, avoid loosening due to vibration and other factors, thereby improving welding accuracy; 2. This solution utilizes the coordinated action of the linkage gear, threaded rod, threaded sleeve, and protrusion with the external gear ring to automatically adjust the position of the welded parts according to the thickness of the instrument components, ensuring the accuracy of the welding position. 3. This solution adopts a worm gear and worm wheel meshing design to ensure that the linkage gear two cannot be actively reversed, further enhancing the stability of the limit frame for the instrument components and improving the welding quality; 4. This solution uses a motor-driven drive gear to rotate the external gear ring, causing the welded parts to move circumferentially, achieving omnidirectional welding of the instrument components and improving welding efficiency and integrity. Other features and advantages of this invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and drawings. Attached Figure Description

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0026] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] Example, refer to Figure 1 A welding device for manufacturing instruments and meters, comprising a base 100 and a positioning seat 200; The base 100 has a guide groove 101. A support plate 102 is telescopically mounted on the base 100 above the guide groove 101. An X-axis motion component is provided in the guide groove 101 to change the position of the support plate 102. A support seat 103 is mounted on the support plate 102.

[0028] Reference Figures 2 to 6The top of the base 100 is fixedly connected to the support plate 201. A positioning seat 200 is installed on one side of the support plate 201, and an extension frame 202 is installed on the top of the support plate 201. A drive gear 203 is hinged to one side of the extension frame 202, and a motor 204 is installed on the other side of the extension frame 202. The motor 204 drives the drive gear 203 to rotate. A guide hole 205 is provided on the positioning seat 200, and a telescopic limit frame 206 is provided on the guide hole 205. The end of the limit frame 206 that extends into the positioning seat 200 is an inclined part 2061. When multiple limit frames 206 extend into the positioning seat 200, the inclined part 2061 can limit the movement of instrument parts of different thicknesses and diameters. A linkage cavity 207 is provided in the positioning seat 200, and toothed grooves are provided on the side of the limit frame 206. A linkage gear 208 is rotatably connected in the linkage cavity 207. The linkage gear 208 meshes with the limit frame 206 for transmission. A threaded rod 209 is coaxially mounted on 208. A threaded sleeve 210 is externally threaded onto the threaded rod 209. A protrusion 211 is mounted on the threaded sleeve 210. When the limiting frame 206 extends or retracts, the limiting frame 206, through meshing transmission, causes the linkage gear 208 to rotate. The linkage gear 208 drives the threaded rod 209 to rotate as well. Under the action of the threaded transmission and the protrusion 211, the threaded rod 209 drives the threaded sleeve 210 to extend or retract. Positioning seat 200 An external gear ring 212 is movably mounted on the outer periphery. The external gear ring 212 meshes with the drive gear 203 for transmission. When the motor 204 rotates, it can drive the external gear ring 212 to rotate through the drive gear 203. An annular groove 213 is opened on the inner edge of the external gear ring 212, and a protrusion 211 is located in the annular groove 213. When the protrusion 211 moves in extension and retraction, it can move in conjunction with the external gear ring 212 to move in extension and retraction. When the external gear ring 212 rotates alone, the protrusion 211 will not be affected. A second linkage gear 214 is hinged in the positioning seat 200. The second linkage gear 214 meshes with the limiting frame 206. A worm gear 215 is installed in the middle section of the second linkage gear 214. A worm 216 meshes with the worm gear 215. A third linkage gear 217 is coaxially mounted on the worm 216. An internal gear ring 218 is rotatably configured on the outer circumference of the positioning seat 200. The internal gear ring 218 meshes with the third linkage gear 217, causing the internal gear ring 218 to rotate. The internal gear ring 218 meshes with the third linkage gear 217, which in turn drives the worm 216. The worm 216 meshes with the worm gear 215. At this time, the second linkage gear 214 rotates together with the worm gear 215. The limiting frame 206 will extend and retract at this time. When multiple limiting frames 206 extend and retract, they can limit the position of the instrument components.

[0029] Reference Figure 2 , 36. A support arm 300 is installed on the side of the external toothed ring 212. A rotating plate 301 is hinged on the support arm 300. A welding part 302 is installed on the rotating plate 301. The welding part 302 is used for welding instruments.

[0030] This implementation achieves the following: The rotating plate 301 is rotated, the mating end of the instrument component is inserted into the positioning seat 200, and the rotating plate 301 is flipped, causing the internal gear ring 218 to rotate. The internal gear ring 218 drives the linkage gear three 217 to rotate. Under the action of the worm 216 and worm wheel 215, the linkage gear three 217 causes the linkage gear two 214 to rotate in the opposite direction. Furthermore, the synergistic action of the worm 216 and worm wheel 215 ensures that the linkage gear two 214 cannot be actively driven to reverse, ensuring that the limiting frame 206, after limiting the instrument component, avoids loosening caused by factors such as vibration, thereby improving welding accuracy. When the linkage gear two 214 rotates, it will cause the limiting frame 206 to extend and retract along the guide hole 205. Multiple limiting frames 206 extend into the positioning seat 200. During the process, the inclined part 2061 can limit the movement of instrument parts with different thicknesses and diameters. During the extension and retraction of the limiting frame 206, under the action of another meshing action, the linkage gear 208 rotates. The threaded rod 209 rotates together with the linkage gear 208. Under the action of the threaded transmission, the threaded sleeve 210 moves in extension and retraction. The protrusion 211 moves in position together with the external gear ring 212 under the action of the annular groove 213. At this time, the position of the welded part 302 can change automatically according to the thickness of the instrument part. The drive gear 203 links with the external gear ring 212 to make the welded part 302 perform circumferential motion, thereby fully welding the instrument part. During this process, the external gear ring 212 will not affect the state of the protrusion 211 and the threaded sleeve 210.

[0031] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts can be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production, requiring minimal experimentation. It should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention and not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
