Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, and more specifically to a method for flange machining tooling. Background Technology

[0002] A flange is a part used to connect shafts, connecting pipe ends, and also on equipment inlets and outlets. When a flange is installed on a curved surface, it is generally designed with an R-shaped line for better fit, facilitating machining and assembly.

[0003] The conventional method for machining the R-shaped line of a flange is gas cutting. Gas cutting involves using a gas cutting tool such as an oxy-acetylene torch to manually cut the R-shaped line of the flange. Then, a template is used to check the cut, and the surface is repeatedly polished until it meets the requirements. However, this machining method only allows for one flange at a time, making batch processing difficult, resulting in long processing times and high costs. Summary of the Invention

[0004] Based on the above description, the present invention provides a flange machining fixture, which aims to solve the problem that existing flange machining fixtures cannot achieve batch processing.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A flange machining fixture includes: The box body has a first receiving groove and a second receiving groove arranged opposite to each other, and a first through hole is formed on a plurality of side walls of the first receiving groove. A clamping device includes a clamping mechanism and a driving mechanism. The number of clamping mechanisms is related to the number of the first through holes, and each clamping mechanism corresponds one-to-one with the first through hole. Each clamping mechanism includes a clamping assembly, a frame, and a connecting arm. The clamping assembly is disposed within the first receiving groove. The clamping assemblies are configured as a pair, symmetrically arranged about the longitudinal axis of the first through hole. The frame is disposed within the second receiving groove, and the connecting arm is movably disposed within the frame. Each clamping assembly includes a support rod, a pressure plate, a limiting rod, and an elastic element. One end of the support rod... The pressure plate is fixed to the side wall or bottom wall of the first receiving groove and is rotatably disposed at the other end of the support rod. The pressure plate has a first clearance hole, and the first receiving groove has a second clearance hole corresponding to the first clearance hole. One end of the limiting rod passes through the first clearance hole and the second clearance hole in sequence and is rotatably connected to the connecting arm. The elastic element is sleeved on the limiting rod. One end of the elastic element abuts against the pressure plate, and the other end of the elastic element abuts against the bottom wall of the first receiving groove. The driving mechanism is disposed in the second receiving groove and is used to drive the connecting arm to move in the vertical direction.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the clamping mechanism includes a housing, the support rod, the pressure plate, the limiting rod, and the elastic element are all located inside the housing, and a third clearance hole for the pressure plate to pass through is opened on the side wall of the housing near the first through hole, and a fourth clearance hole for the limiting rod to pass through is opened on the bottom wall of the housing, and the other end of the elastic element abuts against the bottom wall of the housing.

[0008] Furthermore, each of the two side walls of the frame is provided with at least one sliding groove, and the connecting arm is provided with a sliding protrusion corresponding to each sliding groove, the sliding protrusion slidingly engaging with the sliding groove.

[0009] Furthermore, the top wall of the frame is provided with a connecting hole, and the connecting arm is provided with a screw hole corresponding to the connecting hole. The driving mechanism includes a drive shaft, a first bevel gear, and a transmission assembly. One end of the drive shaft passes through the top wall of the second receiving groove and extends into the first receiving groove. The first bevel gear is sleeved on the other end of the drive shaft. The number of transmission assemblies is related to the number of pressing mechanisms, and the transmission assemblies correspond one-to-one with the pressing mechanisms. The transmission assembly includes a second bevel gear, a synchronous shaft, a transmission unit, and a lead screw connected in sequence. The second bevel gear meshes with the first bevel gear. One end of the lead screw is inserted into the connecting hole, and the lead screw is threaded into the screw hole. The side wall of the frame is provided with a second through hole for the synchronous shaft to pass through.

[0010] Furthermore, a support tube coaxial with the second through hole is provided on the side of the frame near the synchronous shaft.

[0011] Furthermore, a knob is provided at the end of the transmission shaft opposite to the first bevel gear.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: (1) This application enables batch processing of flanges through multiple first through holes. At the same time, the flange is fixed by a clamping device to prevent it from moving during processing, thus ensuring that the flange processing can proceed smoothly.

[0013] (2) The driving mechanism of this application enables multiple connecting arms to move synchronously in the vertical direction, so that multiple clamping mechanisms can simultaneously clamp multiple flanges. This simplifies operation, saves on operating procedures, and thus improves work efficiency. Attached Figure Description

[0020] Reference Figures 1-4As shown, the present invention provides a technical solution: a flange processing fixture, including a box body 10 and a clamping device 20. The box body 10 has a first receiving groove 11 and a second receiving groove 12 arranged opposite to each other. Multiple side walls of the first receiving groove 11 are provided with first through holes 111. The clamping device 20 includes a clamping mechanism 21 and a driving mechanism 22. The number of clamping mechanisms 21 is related to the number of first through holes 111, and each clamping mechanism 21 corresponds one-to-one with a first through hole 111. The clamping mechanism 21 includes a clamping assembly 211, a frame 212, and a connecting arm 213. The clamping assembly 211 is disposed in the first receiving groove 11. The clamping assemblies 211 are configured as a pair, and the pair of clamping assemblies 211 are symmetrically arranged about the longitudinal axis of the first through hole 111. The frame 212 is disposed in the second receiving groove 12, and the connecting arm 213 is movably disposed in the frame 212. Component 211 includes a support rod 2111, a pressure plate 2112, a limiting rod 2113, and an elastic element 2114. One end of the support rod 2111 is fixed to the side wall or bottom wall of the first receiving groove 11. The pressure plate 2112 is rotatably disposed on the other end of the support rod 2111. A first clearance hole 21121 is provided on the pressure plate 2112. A second clearance hole 21121 is provided in the first receiving groove 11 corresponding to the first clearance hole 21121. The limiting rod 2113... One end of 113 passes through the first clearance hole 21121 and the second clearance hole 21121 in sequence and is rotatably connected to the connecting arm 213. The elastic element 2114 is sleeved on the limiting rod 2113. One end of the elastic element 2114 abuts against the pressure plate 2112, and the other end of the elastic element 2114 abuts against the bottom wall of the first receiving groove 11. The driving mechanism 22 is located in the second receiving groove 12 and is used to drive the connecting arm 213 to move in the vertical direction.

[0021] It should be noted that, Figure 1 The longitudinal axis described above is described with reference to the commonly used placement angle of flange machining tooling.

[0022] For example, the drive mechanism 22 can be a pneumatic cylinder, hydraulic cylinder, or electric cylinder, etc., with the output end of the pneumatic cylinder, hydraulic cylinder, or electric cylinder connected to the connecting arm 213; wherein the number of drive mechanisms 22 is related to the number of first through holes 111. The limiting rod 2113 is constructed in a T-shape or cross shape, etc.; wherein the protruding portion of the limiting rod 2113 is located above the pressure plate 2112. The elastic element 2114 can be a spring or elastic rubber ring, etc.

[0023] In this embodiment, after the flange is placed in the first receiving groove 11 and aligned with the first through hole 111, the drive mechanism 22 pushes the limiting rod 2113 downward; and with the support rod 2111 as a fulcrum, the limiting rod 2113 pulls the pressure plate 2112 to rotate downward around one end of the support rod 2111, causing the pressure plate 2112 to contact the flange. This allows the pressure plate 2112 and the bottom wall of the first receiving groove 11 to work together to clamp the flange. This achieves flange fixation, prevents flange movement during processing, and ensures smooth flange processing.

[0024] Reference Figure 1 As shown, in some embodiments, the clamping mechanism 21 includes a housing 2115, a support rod 2111, a pressure plate 2112, a limiting rod 2113, and an elastic member 2114, all located inside the housing 2115. A third clearance hole 21121 for the pressure plate 2112 to pass through is opened on the side wall of the housing 2115 near the first through hole 111, and a fourth clearance hole 21121 for the limiting rod 2113 to pass through is opened on the bottom wall of the housing 2115. The other end of the elastic member 2114 abuts against the bottom wall of the housing 2115.

[0025] In this embodiment, the housing 2115 not only protects the support rod 2111, pressure plate 2112, limiting rod 2113 and elastic element 2114, but also limits the left and right directions of the square flange.

[0026] Reference Figure 1 As shown, in some embodiments, at least one groove 2121 is provided on each pair of sidewalls of the frame 212, and a sliding protrusion 2131 is provided on each groove 2121 of the connecting arm 213, and the sliding protrusion 2131 slides in cooperation with the groove 2121.

[0027] In this embodiment, when the connecting arm 213 moves in the vertical direction, the stability of the movement of the connecting arm 213 can be ensured by the cooperation of the sliding protrusion 2131 and the sliding groove 2121.

[0028] Reference Figure 1As shown, in some embodiments, the top wall of the frame 212 has a connecting hole 2122, and the connecting arm 213 has a screw hole 2132 corresponding to the connecting hole 2122. The driving mechanism 22 includes a drive shaft 221, a first bevel gear 222, and a transmission assembly 223. One end of the drive shaft 221 passes through the top wall of the second receiving groove 12 and extends into the first receiving groove 11. The first bevel gear 222 is sleeved on the other end of the drive shaft 221. The number of transmission assemblies 223 is the same as the number of clamping mechanisms 21. The quantities are related, and the transmission component 223 corresponds one-to-one with the clamping mechanism 21. The transmission component 223 includes a second bevel gear 2231, a synchronous shaft 2232, a transmission unit 2233 and a lead screw 2234 connected in sequence. The second bevel gear 2231 meshes with the first bevel gear 222. One end of the lead screw 2234 is inserted into the connecting hole 2122. The lead screw 2234 is threadedly engaged with the screw hole 2132. The side wall of the frame 212 is provided with a second through hole for the synchronous shaft 2232 to pass through.

[0029] It is worth noting that when there are two or more transmission components 223, since the two second bevel gears 2231 arranged symmetrically rotate in opposite directions, the threads of the two lead screws 2234 arranged symmetrically are reversed.

[0030] For example, the transmission unit 2233 may include two bevel gears, or it may include a worm gear and a worm. When the transmission unit 2233 includes two bevel gears, one bevel gear is sleeved on the synchronous shaft 2232, and the other bevel gear is sleeved on the lead screw 2234. When the transmission unit 2233 includes a worm gear and a worm, the worm gear is sleeved on the lead screw 2234, and one end of the worm is connected to the synchronous shaft 2232. The lead screw 2234 and the connecting hole 2122 may be connected by bearings, etc.

[0031] In this embodiment, the first bevel gear 222 is rotated by rotating the transmission shaft 221, which enables the transmission components 223 to transmit power to the connecting arms 213 in a one-to-one correspondence. This allows multiple connecting arms 213 to move synchronously in the vertical direction, so that multiple clamping mechanisms 21 can simultaneously clamp multiple flanges. This simplifies operation, saves on operational procedures, and thus improves work efficiency.

[0032] Reference Figure 1 As shown, in some embodiments, the frame 212 is provided with a support tube 2123 coaxial with the second through hole on the side near the synchronous shaft 2232.

[0033] In this embodiment, the support tube 2123 provides support for the synchronous shaft 2232, ensuring the stability of the synchronous shaft 2232 transmission.

[0034] Reference Figure 1 As shown, in some embodiments, a knob 224 is provided at the end of the drive shaft 221 that is away from the first bevel gear 222.

[0035] In this embodiment, the knob 224 allows the operator to apply force more easily, thereby improving the convenience of tooling operation.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
