Description

Technical Field

[0001] This utility model relates to the field of abrasive flow machining technology, specifically a tooling adapted for abrasive flow machining of workpieces. Background Technology

[0002] Abrasive flow machining is a surface finishing method that uses high-speed flowing abrasive media to impact and cut the surface of a workpiece. Fixtures are crucial structures used in abrasive flow machining, structurally defining the workpiece to be machined. Existing fixtures for abrasive flow machining utilize jigs to hold the workpiece; however, maintaining a reasonable distance between workpieces during clamping is difficult, and the clamping portion is challenging to process. Therefore, a fixture that addresses these shortcomings is needed to improve the machining effect. Utility Model Content

[0003] The purpose of this utility model is to provide a tooling adapted to workpieces for abrasive flow machining, so as to solve the problem mentioned in the background art that existing tooling for abrasive flow machining of workpieces uses a fixture to hold the workpiece, but it is difficult to ensure a reasonable distance between workpieces and the clamping part is difficult to be processed when holding the workpiece with the fixture.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a tooling adapted for abrasive flow machining, comprising:

[0006] The tooling structure includes an auxiliary pressure plate, a sleeve, and a polyurethane shrink sleeve. The lower end of the sleeve is fitted onto the middle of the upper end of the auxiliary pressure plate, and a fixing block is fitted onto the upper surface of the sleeve. A workpiece support plate is fixed to the upper end of the fixing block, and the workpiece is equidistantly inserted through the edge of the workpiece support plate. A rotating pressure seat is fitted onto the top of the sleeve, and the polyurethane shrink sleeve is fitted onto the lower part of the outer surface of the workpiece.

[0007] Furthermore, a transition plate is fixed to the bottom end of the auxiliary pressure plate, and a base plate is threaded onto the lower end of the transition plate.

[0008] Furthermore, a bearing seat is provided equidistantly around the workpiece in the middle of the base plate, and a bearing sleeve is fitted inside the bearing seat, with the inner wall of the bearing sleeve fitting against the lower end of the workpiece.

[0009] Furthermore, the outer edge of the upper end of the auxiliary pressure plate is fixed with support columns at equal intervals, and the upper end of the support columns is fixed with an upper pressure seat, and the top end of the upper pressure seat is fixed with a clamping flange.

[0010] Furthermore, it also includes a locking structure, which includes a locking screw and a washer. The washer is sleeved on the outer surface of the locking screw, and the screw thread extends to the middle of the top of the sleeve. The inner side of the washer abuts against the upper end of the rotating pressure seat.

[0011] Furthermore, it also includes a quick-connect structure, which includes a connecting threaded tube. The connecting threaded tube is equidistantly opened in the through-hole at the edge of the clamping flange, and the bottom end of the inner wall of the through-hole is provided with a step. Movable springs are fixed equidistantly on the outer side of the step. The connecting threaded tube is provided with a locking post, and a limiting ring is sleeved on the outer edge of the upper end of the locking post. The limiting ring abuts against the top of the movable spring. A limiting hole extending into the clamping flange is opened on one side of the outer surface of the limiting ring, and a limiting post is sleeved in the limiting hole.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes a rotating pressure seat to position and limit the top of the workpiece, while the lower end of the workpiece is compressed by the shrinkage of the polyurethane shrink sleeve during mold closing, ensuring the structural limitation of the lower end of the workpiece. The contact position between the top of the workpiece and the rotating base is a flow opening, which can ensure that the semi-fluid medium can smoothly process the workpiece comprehensively. Furthermore, the equidistant distribution and positioning of the workpiece can further ensure the processing effect. The shrinking polyurethane shrink sleeve can also prevent material leakage, making it convenient to use and meeting the requirements.

[0014] Based on the aforementioned beneficial effects, in the docking of the clamping flange and the abrasive flow mill, a connecting threaded tube is used in conjunction with external bolts for connection and fixation. The connecting threaded tube adopts a limit post connection method, which allows for easy disassembly of the connecting threaded tube when the limit post is removed. If the bolt strips or breaks, it can be directly replaced without having to disassemble the entire structure due to bolt stripping or breakage inside the bolt hole, which is time-consuming and labor-intensive. Furthermore, the elastic force of the movable spring can be used to easily push out the connecting threaded tube, saving time, effort, and costs. Attached Figure Description

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.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-4 As shown, this utility model is a tooling adapted for abrasive flow machining of workpieces, comprising:

[0025] The tooling structure includes an auxiliary pressure plate 11, a sleeve 14, and a polyurethane shrink sleeve. The lower end of the sleeve 14 is fitted onto the middle of the upper end of the auxiliary pressure plate 11, and a fixing block 112 is fitted onto the upper part of the outer surface of the sleeve 14. A workpiece support plate 15 is fixed to the upper end of the fixing block 112, and the workpiece is equidistantly inserted through the edge of the workpiece support plate 15. A rotating pressure seat 16 is fitted onto the top of the sleeve 14, and the polyurethane shrink sleeve is fitted onto the lower part of the outer surface of the workpiece.

[0026] The auxiliary pressure plate 11 provides an installation environment. The sleeve column 14 is used to connect the workpiece support plate 15 with the fixing block 112 so that multiple workpieces can be set at equal intervals through the workpiece support plate 15. The gap between the two is left at the protrusion to ensure the processing requirements. The rotating pressure seat 16 limits the top of the workpiece, and the opening at the joint of the two can meet the processing requirements of the workpiece, ensuring that the workpiece is thoroughly polished.

[0027] A transition plate 110 is fixed to the bottom end of the auxiliary pressure plate 11, and a base plate 111 is threaded onto the lower end of the transition plate 110.

[0028] The base plate 111 has a bearing seat equidistantly arranged around the workpiece in the middle, and a bearing sleeve 18 is fitted inside the bearing seat. The inner wall of the bearing sleeve 18 is in contact with the lower end of the workpiece.

[0029] The bearing seat supports the bottom of the workpiece being ground and uses the bearing bushing 18 to ensure the stability of the connected structure.

[0030] Support columns 12 are fixed at equal intervals on the outer edge of the upper end of the auxiliary pressure plate 11, and an upper pressure seat 13 is fixed on the upper end of the support column 12. A clamping flange 19 is fixed on the top of the upper pressure seat 13.

[0031] The support column 12 is a transitional connection structure that can connect the clamping flange 19 to the auxiliary pressure plate 11. By utilizing the connection between the clamping flange 19 and the abrasive flow mill, the workpiece can be processed smoothly.

[0032] It also includes a locking structure, which includes a locking screw 21 and a washer 22. The washer 22 is sleeved on the outer surface of the locking screw 21, and the threads of the locking screw 21 extend to the middle of the top of the sleeve post 14. The inner side of the washer 22 abuts against the upper end of the rotating pressure seat 16.

[0033] The locking screw 21 provides structural constraint for the installation of the rotating base, and the shim 22 ensures the stability of the structural connection.

[0034] Working principle: The workpieces to be processed are placed into the openings at the edges of the workpiece support plate 15, and a downward force is continuously applied, so that the lower end of the workpiece is in contact with the inner wall of the bearing sleeve 18, the lower part of the outer surface is fitted with the polyurethane shrink sleeve, and the top of the workpiece is placed in the opening at the lower end of the rotating pressure seat 16, with the two in contact. The rotating pressure seat 16 is then fixed by locking screws 21 and shims 22. Then, the entire fixture is installed on the abrasive flow mill using the clamping flange 19. After processing is completed, the actual steps are reversed to remove the workpiece.

[0035] This solution ensures the integrity of the workpiece surface processing, improves the performance, and meets the usage requirements.

[0036] Please see Figure 1-4As shown, this embodiment, based on the above embodiment, also includes a quick docking structure. The quick docking structure includes a docking screw tube 31, which is equidistantly opened in the through-hole on the edge of the clamping flange 19. The bottom end of the inner wall of the through-hole is provided with a step 32. Movable springs 33 are fixed equidistantly on the outer side of the step 32. The internal thread of the docking screw tube 31 is provided with a locking post, and a limiting ring 34 is sleeved on the outer edge of the upper end of the locking post. The limiting ring 34 abuts against the top of the movable spring 33. A limiting hole 35 extending out of the clamping flange 19 is opened on one side of the outer surface of the limiting ring 34, and a limiting post 36 is sleeved in the limiting hole 35.

[0037] The connecting threaded tube 31, in conjunction with external bolts, allows the clamping flange 19 to be connected and installed with an external abrasive flow machine to meet the processing requirements of the workpiece. The step 32 supports the movable spring 33, and through contact with the limiting ring 34, a reverse force is applied after the force is released, which can easily push the connecting threaded tube 31 out of the through-hole. The limiting post 36 extends into the limiting hole 35, which can limit the connecting threaded tube 31 inside the through-hole.

[0038] Working principle: When connecting the tooling to the external abrasive flow machine, insert the connecting threaded tube 31 into the multiple through holes on the clamping flange 19 beforehand. Under the pressure, the movable spring 33 is compressed, so that the connecting threaded tube 31 and the limiting hole 35 on the clamping flange 19 are aligned. Then, the limiting post 36 is inserted into the limiting hole 35 to limit the structure of the locking threaded tube. Then, use external bolts to connect the clamping flange 19 to the external abrasive flow machine. When disassembling, apply the reverse steps.

[0039] This solution allows for easy disassembly and assembly of the clamping tube, and avoids bolt stripping or breakage in the screw hole, thus reducing the need for complete replacement and lowering costs.
