Description

Technical Field

[0001] This utility model belongs to the field of clamping tooling technology, specifically relating to a soft claw clamping tooling for a marine turbocharger housing. Background Technology

[0002] The turbocharger housing, also known as the "volute housing" or "spiral housing," is one of the core stationary components of a turbocharger. It acts as the "body" or "channel system" of the turbocharger, responsible for guiding and containing exhaust gas and fresh air, and is a crucial site for energy conversion. As a key component of the turbocharger, the turbocharger housing is typically made of heat-resistant alloy cast iron or similar materials through precision casting. These parts have complex structures, often featuring thin-walled, hollow volute shapes. Furthermore, the inner surfaces of the flow channels, end faces, and various connecting flanges require high-precision machining to ensure final assembly accuracy and performance.

[0003] In existing technologies, when performing turning, boring, and other processes on turbocharger housings, traditional three-jaw chucks or specialized hydraulic clamps are commonly used for peripheral clamping, i.e., the workpiece is fixed by applying radial clamping force from the outside of the part. However, this traditional clamping method has the following significant drawbacks: because the turbocharger housing itself is a thin-walled component with relatively poor rigidity, deformation is prone to occur when clamping the outer periphery of the housing. Utility Model Content

[0004] Based on the problems mentioned in the background technology above, this utility model provides a soft claw clamping fixture for marine turbocharger housing, which solves the problem that the outer periphery of the turbocharger housing is easily deformed when using traditional three-jaw chucks or special hydraulic clamps to hold and stabilize the turbocharger housing.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A marine turbocharger housing soft claw clamping fixture includes:

[0007] abutment;

[0008] An assembly platform, which is securely and detachably mounted on top of a base;

[0009] Adjustable internal support components, wherein three adjustable internal support components are provided and are respectively arranged in an array on the top of the assembly table;

[0010] The support components are provided in three arrays on the top of the assembly platform and are staggered from the positions of the three adjustable inner support components.

[0011] Based on the above technical solution, the present invention has made the following improvements:

[0012] Furthermore, the adjustable internal support component includes a slot, which is disposed on the top of the assembly table, with one end of the slot facing the center of the assembly table and the other end facing the outer periphery of the assembly table. An assembly block is fastened in the slot, and an L-shaped block is detachably disposed on the top of the assembly block. A rubber block is disposed on the side wall of the vertical part of the L-shaped block facing away from the center of the assembly table by screws. The rubber block can achieve a certain elastic deformation along the direction towards the center of the assembly table.

[0013] Furthermore, the top of the assembly block is provided with multiple screw holes, and a connecting screw is smoothly inserted vertically on the horizontal part of the L-shaped block, with the threaded end of the connecting screw screw screwed into the corresponding screw hole.

[0014] Furthermore, the supporting component includes a mounting groove, which is disposed on the top of the assembly platform, with one end of the groove facing the center of the assembly platform and the other end facing the outer periphery of the assembly platform. The bottom of the mounting groove is provided with multiple receiving holes. T-slots are provided on both sides of the mounting groove. A mounting block is slidably disposed on the top of the mounting groove. A support rod is vertically threaded into the middle of the mounting block. Locking screws are vertically threaded into both sides of the top of the mounting block. T-blocks are smoothly rotated and fitted onto the bottom ends of the two locking screws. The two T-blocks are respectively located in the corresponding T-slots.

[0015] Furthermore, the top array of the base is provided with multiple docking posts, and the bottom array of the assembly platform is provided with multiple docking holes, with each docking post tightly engaged in the corresponding docking hole.

[0016] Furthermore, the top periphery of the base is arrayed with multiple connection holes.

[0017] The beneficial effects of this utility model are:

[0018] 1. By combining the base, assembly table, and three adjustable internal support components, the base is installed on the machine tool's worktable. Then, the three adjustable internal support components are used to support the inner circumferential wall of the intensifier housing's flange ring. Because the flange ring of the intensifier housing is relatively thick, the intensifier housing will not be deformed or damaged when the internal support stabilizes it.

[0019] 2. By using the three supporting components, after the three adjustable internal support components are supported on the inner circumferential wall of the flange ring of the turbocharger housing, the three supporting components are also pushed against the bottom of the flange ring to provide vertical limit for the turbocharger housing, thereby further improving the stability of the turbocharger housing.

[0026] like Figures 1-3 As shown, a soft-claw clamping fixture for a marine turbocharger housing includes:

[0027] Base 101, with multiple docking posts 103 arranged in an array on the top of base 101;

[0028] Assembly table 201 has multiple docking holes 202 arranged in an array at its bottom, and each docking post 103 is tightly engaged in the corresponding docking hole 202. The docking post 103 and the docking hole 202 adopt a transition fit, so that the assembly table 201 is securely and detachably mounted on the top of the base 101. Multiple connecting holes 102 are arranged in an array on the top periphery of the base 101. In use, this tooling is placed on the worktable of the machine tool, and then bolts are passed through each connecting hole 102. The inserted end of the bolt is screwed into the threaded hole of the worktable of the machine tool, so that the tooling is assembled on the worktable of the machine tool.

[0029] The adjustable internal support component includes three components arranged in an array on the top of the assembly platform 201. Each adjustable internal support component includes a slot 301, which is located on the top of the assembly platform 201. One end of the slot faces the center of the assembly platform 201, and the other end faces the outer periphery of the assembly platform 201. An assembly block 302 is fastened in the slot 301, and the assembly block 302 and the slot 301 are in a transition fit.

[0030] An L-shaped block 304 is detachably provided on the top of the assembly block 302. Multiple screw holes 303 are arrayed on the top of the assembly block 302. A connecting screw 305 is smoothly passed through the horizontal part of the L-shaped block 304. The threaded end of the connecting screw 305 is screwed into the corresponding screw hole 303, thereby realizing the detachable assembly of the L-shaped block 304 on the top of the assembly block 302.

[0031] A rubber block 306 is installed on the side wall of the vertical part of the L-shaped block 304 facing away from the center of the assembly table 201 by screws. When the rubber block 306 is squeezed in the direction towards the center of the assembly table 201, the rubber block 306 can achieve a certain elastic deformation in the direction towards the center of the assembly table 201.

[0032] The support components are arranged in three arrays on the top of the assembly platform 201 and are staggered from the positions of the three adjustable inner support components. The support components include mounting grooves 401, which are located on the top of the assembly platform 201, with one end of the groove facing the center of the assembly platform 201 and the other end facing the outer periphery of the assembly platform 201. Multiple receiving holes 402 are arrayed on the bottom of the mounting groove 401. T-slots 403 are provided on both sides of the mounting groove 401. A mounting block 404 is slidably mounted on the top of the mounting groove 401. A support rod 407 is vertically threaded into the middle of the mounting block 404. The support rod 407 can rotate and move up and down in the middle of the mounting block 404, and the bottom end of the support rod 407 can be stored in the receiving hole 402.

[0033] Both sides of the top of the mounting block 404 are vertically threaded with locking screws 405. The bottom ends of the two locking screws 405 are smoothly fitted with T-shaped blocks 406. The two T-shaped blocks 406 are respectively located in the corresponding T-shaped grooves 403. When the locking screws 405 rotate and move up and down, the locking screws 405 rotate independently relative to the T-shaped blocks 406. That is, when the locking screws 405 rotate, the T-shaped blocks 406 do not rotate with them, but only move up and down.

[0034] In use, place the base 101 on the machine tool's worktable, then insert the bolts into each connecting hole 102, and screw the bolt ends into the threaded holes on the machine tool's worktable to assemble the fixture onto the worktable. Next, assemble the three L-shaped blocks 304 onto the top of their respective assembly blocks 302, ensuring that the diameter of the circle formed by the friction walls of the three rubber blocks 306 is slightly larger than the inner diameter of the flange ring at the bottom of the ship's turbocharger housing. Then, place the bottom edge of the flange ring at the bottom of the ship's turbocharger housing on top of the friction walls of the three rubber blocks 306, and then press down on the ship's turbocharger housing. The turbocharger housing is constructed such that the bottom edge of the flange ring moves downward to squeeze the friction wall of the three rubber blocks 306. This causes the three rubber blocks 306 to undergo a certain elastic retraction deformation in the direction towards the center of the assembly platform 201. This allows the flange ring at the bottom of the turbocharger housing to be pressed down and moved tightly between the three rubber blocks 306. Ultimately, the three rubber blocks 306 are used to internally support and stabilize the flange ring at the bottom of the turbocharger housing. Because the flange ring of the turbocharger housing is relatively thick, the turbocharger housing will not be deformed or damaged when the three rubber blocks 306 internally support and stabilize it.

[0035] Meanwhile, the bottom of the bottom flange of the turbocharger housing also abuts against the top of the support rod 407, so that the support rod 407 plays a role in supporting and limiting the vertical position of the turbocharger housing, further improving the stability of the turbocharger housing.
