Description

Technical Field

[0001] This invention relates to the field of cage processing technology, specifically to cage processing methods and fixing fixtures. Background Technology

[0002] The cage is formed by riveting together a cage seat and a cage cover. When machining the cage, it is usually necessary to machine pocket holes on the cage seat and corresponding rivet holes on the cage seat and cage cover.

[0003] Currently, the pockets and rivet holes need to be processed in separate steps. Before processing, each step requires two separate centering, machining position confirmation, and positioning checks using a dedicated fixing jig. This results in low processing efficiency and low processing accuracy. In addition, the dedicated fixing jig also needs to be processed separately, which is time-consuming, inefficient, and may even result in insufficient machining accuracy of the dedicated fixing jig, thus affecting the machining accuracy of the cage. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a cage machining method and a fixing fixture. The machining of the pressure plate is completed simultaneously when machining the first cage seat and the first cage cover, shortening the machining time of the fixing fixture and reducing the machining difficulty. Furthermore, the present invention uses only one fixing fixture to machine the cage seat and cage cover, ensuring the concentricity of the cage seat and cage cover, facilitating the confirmation of the machining positions of the pockets and rivet holes, thereby improving the machining accuracy of the rivet holes and pockets.

[0005] To achieve the above objectives, the technical solution provided by the present invention is a cage processing method, which includes step S100: making a fixing fixture, wherein making the fixing fixture includes the step of processing a fixing base and the step of pre-processing a pressure plate.

[0006] The steps of processing the fixed base include taking a first circular plate and processing rivet hole angle points and pocket angle points that are equidistant from the center of the first circular plate.

[0007] The pre-processing pressure plate step includes taking a second circular plate, processing an angle adjustment hole on the second circular plate, and the distance between the angle adjustment hole and the center position of the second circular plate is equal to the distance between the rivet hole angle point and the center position of the first circular plate.

[0008] Step S200: Install the first retainer seat on the fixed base, cover the first retainer cover on the first retainer seat, and press the pressure plate onto the first retainer cover;

[0009] Step S300: The pressure plate is pressed onto the first retainer cover, the angle adjustment hole corresponds to the angle point of the rivet hole, the fixed base and the pressure plate are locked, and the rivet hole is machined simultaneously on the first retainer base and the first retainer cover;

[0010] Step S400: Remove the pressure plate and retainer cover, reinstall the pressure plate, the pressure plate is pressed onto the first retainer seat, the angle adjustment hole and the pocket angle point correspond, lock the fixed base and the pressure plate, while machining the pocket on the first retainer seat, at the same time machining the clearance notch on the outer circumference of the pressure plate;

[0011] Step S500: The pressure plate processing is completed;

[0012] Step S600: Use a fixed fixture to process the retainer base and retainer cover. The fixed fixture includes the pressure plate confirmed as qualified in step S500 and the fixed base processed in step S100.

[0013] Further, step S600 includes:

[0014] Step S610: Install the cage seat on the fixed base, cover the cage cover on the cage seat, and press the pressure plate onto the cage cover;

[0015] Step S620: Adjust the pressure plate so that it is pressed onto the retainer cover, the angle adjustment hole corresponds to the angle point of the rivet hole, lock the fixed base and the pressure plate, and process the rivet hole;

[0016] Step S630: Remove the pressure plate and retainer cover, reinstall the pressure plate, adjust the pressure plate so that the pressure plate is pressed onto the retainer seat, the angle adjustment hole and the pocket angle point correspond, lock the fixed base and the pressure plate, and machine the pocket.

[0017] Furthermore, the step of processing the fixed base includes processing a base center positioning hole at the center position of the first circular plate, and processing a plurality of base mounting holes equidistant from the base center positioning hole on the first circular plate.

[0018] Furthermore, the step of pre-processing the pressure plate includes processing a pressure plate center positioning hole at the center position of the second circular plate, and processing a plurality of pressure plate mounting holes equidistant from the pressure plate center positioning hole on the second circular plate.

[0019] Further, the step of locking the fixed base and the pressure plate in steps S300 and S400 includes:

[0020] A circumferential locking element is used to connect the pressure plate mounting hole to the base mounting hole, and a centering locking element is used to connect the pressure plate center positioning hole to the base center positioning hole.

[0021] Further, the step of locking the fixed base and the pressure plate in steps S620 and S630 includes:

[0022] A circumferential locking element is used to connect the pressure plate mounting hole to the base mounting hole, and a centering locking element is used to connect the pressure plate center positioning hole to the base center positioning hole.

[0023] Furthermore, the mounting hole for the pressure plate is an arc-shaped waist hole.

[0024] Furthermore, the step of machining the fixed base includes machining an annular groove on the outer circumference of one side end face of the first circular plate to form a protrusion for engaging with the inner diameter of the retainer base.

[0025] Furthermore, step S500 includes assembling the first cage seat and the first cage cover, and confirming that the first cage seat and the first cage cover are qualified, so as to confirm that the pressure plate processing is qualified.

[0026] The retainer is made by steps S100-S500 of the above-described retainer processing method.

[0027] The beneficial effects of this invention are as follows: When machining the first cage seat and the first cage cover, the pressure plate is machined simultaneously. Specifically, the clearance notch around the pressure plate does not need to be machined separately, avoiding the positioning and indexing steps required for separate machining of the clearance notch. The clearance notch is machined simultaneously with the pocket, shortening the machining time of the fixed fixture and reducing the machining difficulty. Only the machining accuracy of the first cage seat and the first cage cover needs to be ensured, thus simultaneously confirming the machining accuracy of the pressure plate. After machining the clearance notch, when machining other cage seats and cage covers using the fixed fixture, the consumption of the pressure plate can be minimized, preventing the pressure plate from being repeatedly cut by the pocket drill bit, which could ultimately prevent it from effectively holding the cage cover and cage seat in place. The invention uses a single fixed fixture to machine the cage seats and cage covers, ensuring the concentricity of the cage seats and cage covers, facilitating the confirmation of the machining positions of the pockets and rivet holes, and thus improving the machining accuracy of the rivet holes and pockets.

[0050] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0051] A cage machining method for machining the cage seat 10 and the cage cover 20, see [link to documentation]. Figures 1-4 The structure of the cage base 10 and the cage cover 20 is shown. The cage base 10 and the cage cover 20 need to be machined with corresponding cage base rivet holes 31 and cage cover rivet holes 32, and the cage base 10 needs to be machined with pocket holes 41.

[0052] In one embodiment of the present invention, the specific steps of the cage processing method include:

[0053] See Figure 5 and Figure 6 Step S100: Making a fixed fixture, which includes the steps of machining the fixed base 100 and pre-machining the pressure plate 200.

[0054] The step of processing the fixed base 100 includes taking a first circular plate and processing rivet hole angle points 110 and pocket angle points 120 that are equidistant from the center of the first circular plate. That is, rivet hole angle points 110 and pocket angle points 120 are in the same radial position. The processing methods of rivet hole angle points 110 and pocket angle points 120 include, but are not limited to, engraving, marking and drilling.

[0055] The steps of pre-processing the pressure plate 200 include taking a second circular plate and machining an angle adjustment hole 210 on the second circular plate. The distance between the angle adjustment hole 210 and the center position of the second circular plate is equal to the distance between the rivet hole angle point 110 and the center position of the first circular plate. This ensures that when the first circular plate and the second circular plate are coaxially set, the angle adjustment hole 210 can rotate and can switch between positions coaxial with the rivet hole angle point 110 and the pocket hole angle point 120 during the rotation.

[0056] See Figure 7 and Figure 8 Step S200: Install the first retainer seat 11 on the fixed base 100, cover the first retainer cover 21 on the first retainer seat 11, and press the pressure plate 200 on the first retainer cover 21.

[0057] Step S300, as follows Figure 8 As shown, the pressure plate 200 is pressed onto the first retainer cover 21, and the angle adjustment hole 210 corresponds to the rivet hole angle point 110. The base 100 and the pressure plate 200 are locked and fixed. A rivet hole drill bit 30 is used to simultaneously machine the retainer seat rivet hole 31 and the retainer cover rivet hole 32 on the first retainer seat 11 and the first retainer cover 21. In this step, since the pressure plate 200 is pressed onto the upper part of the first retainer cover 21, the pressure plate 200 will also be simultaneously machined with circumferentially distributed holes, such as... Figure 9 As shown.

[0058] See Figure 10 and Figure 11 In step S400, disassemble the pressure plate 200 and the retainer cover 21, simultaneously rotate the fixed base 100 and the first retainer seat 11 on the upper part of the fixed base 100 by a certain angle, reinstall the pressure plate 200, press the pressure plate 200 onto the first retainer seat 11, with the angle adjustment hole 210 corresponding to the pocket angle point 120, and lock the fixed base 100 and the pressure plate 200. Simultaneously, using a pocket drill bit 40, machine a pocket 41 on the first retainer seat 11 and a clearance notch 240 on the outer circumference of the pressure plate 200. Figure 12 As shown.

[0059] Step S500, pressure plate 200 processing completed;

[0060] See Figures 13-16 In step S600, the cage seat 10 and cage cover 20 are processed using a fixed fixture. The fixed fixture includes the pressure plate 200 that has been confirmed as qualified in step S500 and the fixed base 100 processed in step S100. It should be noted that the cage seat 10 in this step refers to any cage seat other than the first cage seat 11 to be processed, and the cage cover 20 refers to any cage cover other than the cage cover 21 to be processed.

[0061] Further, step S600 includes:

[0062] Step S610: Install the retainer base 10 on the fixed base 100, cover the retainer cover 20 on the retainer base 10, and press the pressure plate 200 on the retainer cover 20.

[0063] Step S620: Adjust the pressure plate 200 so that the pressure plate 200 is pressed onto the cage cover 20, the angle adjustment hole 210 corresponds to the rivet hole angle point 110, lock and fix the base 100 and the pressure plate 200, and use the rivet hole drill bit 30 to simultaneously machine the cage seat rivet hole 31 and the cage cover rivet hole 32 on the cage seat 10 and the cage cover 20.

[0064] Step S630: Remove the pressure plate 200 and the retainer cover 20. Rotate the fixed base 100 and the retainer seat 10 on the upper part of the fixed base 100 at the same time by a certain angle. Reinstall the pressure plate 200 so that the pressure plate 200 is pressed onto the retainer seat 10. The angle adjustment hole 210 corresponds to the pocket angle point 120. Lock the fixed base 100 and the pressure plate 200. Use the pocket drill bit 40 to process the pocket 41.

[0065] In the aforementioned cage machining method, the pressure plate 200 is machined simultaneously when machining the first cage seat 11 and the first cage cover 21. Specifically, the clearance notch 240 around the pressure plate 200 does not need to be machined separately, avoiding the positioning and indexing steps required for machining the clearance notch 240 separately. The clearance notch 240 is machined simultaneously with the pocket 41, shortening the machining time of the fixed fixture and reducing the machining difficulty. Only the machining accuracy of the first cage seat 11 and the first cage cover 21 needs to be ensured to simultaneously confirm the machining accuracy of the pressure plate 200. After machining the clearance notch 240, when machining other cage seats and other cage covers using the fixed fixture, it can be ensured that the machining area is inside the clearance notch 240, minimizing the consumption of the pressure plate 200 and preventing the pressure plate 200 from being repeatedly cut by the pocket drill bit 40, which would ultimately prevent it from fulfilling its function of pressing down the cage cover 20 and the cage seat 10. The other cage seats 10 and other cage covers 20 are processed using a pre-made fixed fixture. The present invention can process the cage seats 10 and cage covers 20 with a single fixed fixture, which can ensure the concentricity of the cage seats 10 and cage covers 20, facilitate the confirmation of the processing position of the pocket holes 41 and rivet holes, and thus improve the processing accuracy of the rivet holes and pocket holes 41.

[0066] See Figure 1In one embodiment, the step of processing the fixed base 100 includes processing a base center positioning hole 130 at the center position of the first circular plate, and processing a plurality of base mounting holes 140 at equal distances from the base center positioning hole 130 on the first circular plate.

[0067] See Figure 12 In one embodiment, the step of pre-processing the pressure plate 200 includes processing a pressure plate center positioning hole 220 at the center position of the second circular plate, and processing a plurality of pressure plate mounting holes 230 at equal distances from the pressure plate center positioning hole 220 on the second circular plate.

[0068] In one embodiment, the steps of locking and fixing the base 100 and the pressure plate 200 in steps S300 and S400 include:

[0069] A circumferential locking member 400 is used to pass through the pressure plate mounting hole 230 and connect to the base mounting hole 140, and a centering locking member 300 is used to pass through the pressure plate center positioning hole 220 and connect to the base center positioning hole 130.

[0070] In one embodiment, the steps of locking and fixing the base 100 and the pressure plate 200 in steps S620 and S630 include:

[0071] A circumferential locking member 400 is used to pass through the pressure plate mounting hole 230 and connect to the base mounting hole 140, and a centering locking member 300 is used to pass through the pressure plate center positioning hole 220 and connect to the base center positioning hole 130.

[0072] See Figure 12 In one embodiment, the pressure plate mounting hole 230 is an arc-shaped waist hole. With this configuration, when adjusting the relative position of the pressure plate 200 and the fixed base 100, the circumferential locking member 400 can slide and adjust inside the arc-shaped waist hole according to the position of the base mounting hole 140 on the fixed base 100 after relative rotation, and is threadedly connected to the base mounting hole 140, thereby improving the flexibility of the device, facilitating operation, and improving positioning and processing efficiency.

[0073] In one embodiment, the step of machining the fixed base 100 includes machining an annular groove on the outer circumference of one side end face of the first circular plate to form a protrusion 150 for engaging with the inner diameter of the retainer seat 20. The protrusion 150 is a columnar structure protruding from the fixed base 100, and the outer diameter of the columnar structure engages with the inner diameter of the retainer seat 10 to position the inner diameter of the retainer seat 10, thereby preventing unnecessary radial displacement of the retainer seat 10 and retainer cover 20 during machining and improving machining accuracy. In addition to the arrangement in this embodiment, in other embodiments, the protrusion 150 can also be configured as an annular structure, and the outer diameter of the annular structure engages with the inner diameter of the retainer seat 10 to position the inner diameter of the retainer seat 10.

[0074] In one embodiment, step S500 includes assembling the first cage seat 11 and the first cage cover 21, and confirming that the first cage seat 11 and the first cage cover 21 are qualified, so as to confirm that the pressure plate 200 is qualified.

[0075] The cage machining fixture is manufactured using steps S100-S500 of the cage machining method described above. This invention allows for the machining of both the cage seat and cage cover using a single fixture, ensuring concentricity of the cage seat and cover, facilitating the confirmation of the machining positions of the pockets and rivet holes, and thus improving the machining accuracy of the rivet holes and pockets.

[0076] The pressure plate 200 has a first assembly state for machining the rivet holes 31 of the cage seat and the rivet holes 32 of the cage cover, and a second assembly state for machining the pocket hole 41. In the first assembly state, the pressure plate 200 is pressed onto the cage cover 20, which is mounted on the upper part of the cage seat 10. The angle adjustment hole 210 corresponds to the rivet hole angle point 110. At this time, the rivet holes 31 of the cage seat and 32 of the cage cover can be machined simultaneously on the cage cover 20 and the cage seat 10. In the second assembly state, the pressure plate 200 is pressed onto the cage seat 10, the cage cover 20 is removed, and the angle adjustment hole 210 corresponds to the pocket hole angle point 120. At this time, the pocket hole 41 can be machined on the cage seat 10.

[0077] It should be noted that in this embodiment, the rivet hole angle point 110 is a marker point. The pocket angle point 120 is also a marker point. This allows the rivet hole angle point 110 to be seen through the angle adjustment hole 210 when the pressure plate 200 is in the first assembly state, thereby confirming the machining position of the retainer seat rivet hole 31 and the retainer cover rivet hole 32. Similarly, when the pressure plate 200 is rotated relative to the fixed base 100 to the second assembly state, the pocket angle point 120 can be seen through the angle adjustment hole 210, thereby confirming the machining position of the pocket 41. A single fixed fixture can be used to machine the retainer seat and retainer cover, facilitating the adjustment and confirmation of the machining positions of the pocket 41, retainer seat rivet hole 31, and retainer cover rivet hole 32, thus improving the machining accuracy of the pocket 41, retainer seat rivet hole 31, and retainer cover rivet hole 32. It should be noted that the rivet hole angle point 110 and the pocket angle point 120 can also be through holes or blind holes. When the rivet hole angle point 110 and the pocket angle point 120 are through holes or blind holes, a calibration rod can be inserted into the angle adjustment hole 210 to confirm the position. When the end of the calibration rod is inserted into the rivet hole angle point 110, the rivet hole angle point 110 corresponds to the angle adjustment hole 210. When the end of the calibration rod is inserted into the pocket angle point 120, the pocket angle point 120 corresponds to the angle adjustment hole 210.
