Description

Technical Field

[0001] The present invention relates to the technical field of speed reducer processing, and in particular to a speed reducer self-boring processing device and a use method thereof. Background Art

[0002] As a precision transmission device, the reducer's housing must bear the dynamic loads of the gear, worm, or gear-worm transmission system, and achieve power transmission and speed matching through the rigid housing. Self-boring machining technology directly determines the dimensional accuracy and geometric tolerances of key parts such as bearing mounting holes and planetary gear positioning holes, which in turn affects the transmission efficiency and service life of the reducer. Current technologies have the following common drawbacks:

[0003] Insufficient kinematic coupling

[0004] Existing machining systems use independent drive units to control feed, cutting, and chip removal actions separately, resulting in low energy conversion efficiency. The split power configuration is prone to motion mismatch. For example, when the tool feed speed is not synchronized with the spindle speed, cutting steps or tool let-down are likely to occur.

[0005] Debris processing lags

[0006] Traditional suction devices do not achieve suction channel maintenance, and there is a high probability that debris will accumulate in the channel to form blockages, requiring frequent shutdowns for cleaning.

[0007] In view of this, we propose a self-boring processing device for a reducer and a method for using the same. Summary of the Invention

[0008] The purpose of the present invention is to provide a self-boring processing device for a reducer and a method for using the same, so as to solve the problems of insufficient motion coupling and delayed chip processing raised in the above-mentioned background art. To achieve the above-mentioned purpose, the present invention provides the following technical solution: a self-boring processing device for a reducer, comprising a processing table for fixing the reducer, the reducer being provided with a motor for driving the reducer, a sleeve being fixedly provided on the processing table, and an outer disk being movably provided within the sleeve, the outer disk being fixedly provided with a plug for plugging into the reducer shaft, and a turning tool for cutting the reducer being fixedly provided on the outer disk.

[0009] An inner disk is provided in the sleeve, three guide rods passing through the inner disk are fixedly provided on the outer disk, and an elastic member is provided between the outer disk and the inner disk. A spiral track is provided on the inner wall of the sleeve, and an insert is provided on the outer ring of the inner disk that moves along the track. The insert drives the inner disk to move along the guide rod, and the end of the track is provided with an annular groove for the inner disk to rotate.

[0010] A circular cover is fixedly arranged on the inner disk, and the circular cover is located between the outer disk and the sleeve.

[0011] Preferably, the guide rod is a hollow structure and passes through the outer disk to form a suction port for sucking debris.

[0012] Preferably, an extrusion column for squeezing debris is movably provided inside the guide rod, and a magnetic sheet is provided on the inner wall of the guide rod, and the magnetic sheet utilizes magnetic force to adsorb the extrusion column and the suction port so as to be misaligned.

[0013] The inner side wall of the annular groove is provided with a plurality of extrusion inserts and a top block for the displacement of the inner disk. The outside of the guide rod is provided with a sliding opening connected with the interior thereof, and a protrusion is slidingly provided in the sliding opening. When the annular groove is displaced, the inner disk moves along the protrusion to push the extrusion column to extrude the suction area in the guide rod.

[0014] Preferably, a toothed edge is provided on the inner side wall of one side of the guide rod, and a ring tooth is provided on the end of the extrusion column, and the extrusion column is driven to rotate along the toothed edge by the ring tooth when extruding the suction area.

[0015] Preferably, the turning tool can achieve radial and axial position adjustment through an adjusting device.

[0016] Preferably, it also includes a debris recovery system, and the guide rod is connected to the negative pressure generator through a bellows to form a continuous suction channel from the suction port to the dust collecting chamber.

[0017] Preferably, the adjustment device includes an axial adjustment module and a radial adjustment module, wherein:

[0018] The ‌Axial Adjustment Module‌ consists of a worm gear assembly that drives a worm gear connected to the turning tool to achieve axial displacement by rotating the worm gear.

[0019] The radial adjustment module is equipped with a fine-tuning screw and a locking nut with scale markings, and the radial feed of the turning tool is controlled by rotating the screw.

[0020] A method for using a self-boring processing device for a reducer comprises the following steps:

[0021] S1. Fix the reducer according to the position on the processing table, insert the shaft of the reducer into the plug for connection, and then install the motor to drive the reducer, plug and outer disk to rotate;

[0022] S2. The outer disc drives the inner disc to rotate using the guide rod. The synchronously moving insert enters the ring groove along the track to drive the inner disc close to the outer disc, so that the elastic member squeezes the turning tool on the outer disc to fit the reducer for turning. In this way, the outer disc uses its own rotation to drive itself and the turning tool to cooperate with the reducer.

[0023] S3. During the turning process, the suction port sucks the chips generated by the machining and discharges them through the guide rod. As the insert rotates along the annular groove, the top block pushes the inner disk to move back and forth along the guide rod, and the convex block pushes the extrusion column in the guide rod to move back and forth radially toward the suction area. In this way, the inner disk rotates to control the extrusion column to compress the chips stuck in the suction area.

[0024] S4. When the extrusion column moves radially toward the suction area, the ring teeth engage with the tooth edges to realize the self-rotation of the extrusion column, thereby utilizing the rolling extrusion column to rub the sharp edges and corners of the debris.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the present invention, the integrated self-driven turning mechanism

[0027] The outer disc forms a linkage mechanism with the inner disc through a guide rod. When the insert slides into the annular groove along the track, the inner disc is driven close to the outer disc. At this time, the elastic member presses the outer disc and the turning tool against the surface of the reducer. This design synchronously drives the turning tool feed through the rotation of the outer disc, realizing the mechanical coupling of the turning action and the rotational motion, eliminating the need for an independent control unit and significantly improving the degree of machining automation.

[0028] In the present invention, the dynamic debris removal system

[0029] The suction port and the guide rod form a negative pressure channel. During the debris suction process:

[0030] The top block in the annular groove triggers the axial displacement of the insert, driving the inner disk to reciprocate along the guide rod. The protrusion converts the reciprocating motion into radial pulse action of the extrusion column, implementing periodic compression on the suction area. This dual-mode motion increases the debris density and completely solves the problem of internal metal chip retention.

[0031] In the present invention, the debris passivation treatment mechanism

[0032] When the extrusion column moves radially, the ring teeth on its surface engage with the fixed tooth edges to produce rotation, and the sharp corners of the debris are worn away by rolling friction, reducing the volume of the debris. This process simultaneously optimizes the debris morphology, reducing the risk of scratches in the subsequent collection link by 90%. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 12 As shown, the guide rod 11 is a hollow structure and passes through the outer disk 7 to form a suction port 15 for sucking debris.

[0051] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 12 As shown, an extrusion column 16 for squeezing debris is movably provided inside the guide rod 11, and a magnetic sheet 17 is provided on the inner wall of the guide rod 11. The magnetic sheet 17 uses magnetic force to absorb the extrusion column 16 and the suction port 15 to be misaligned.

[0052] The inner wall of the annular groove 6 is provided with a plurality of extrusion inserts 13 and a top block 18 for the displacement of the inner disk 10. A sliding port 19 communicating with the interior of the guide rod 11 is provided on the outside of the guide rod 11, and a protrusion 20 is slidingly provided in the sliding port 19.

A torque sensor is added at the junction of the guide rod 11 and the outer disk 7. When the turning resistance exceeds the threshold, the electromagnetic damper is triggered to reduce the rotation speed of the outer disk 7 and synchronously adjust the negative pressure value of the suction port 15 to ensure that the debris removal rate and the material removal rate are dynamically matched.

The guide rod 11 is connected to the negative pressure generator through a bellows, forming a continuous suction channel from the suction port 15 to the dust collecting chamber. The flexible connection design of the bellows compensates for the vibration displacement of the equipment and cooperates with the negative pressure generator to achieve continuous suction and reduce the amount of debris residue. The inner diameter of the guide rod 11 is matched with the negative pressure pipe diameter at a ratio of 1:1.5 to ensure a 100% metal chip passing rate and avoid the common problem of chip accumulation in pipes in traditional systems.

A digital torque display is added to the end of the worm, allowing the operator to monitor the adjustment force in real time to prevent overload damage to the tool. The scale markings of the radial module are coated with fluorescent coating, which can still be clearly identified during processing in dark environments, shortening the tool change time.

[0062] S3. During the turning process of the turning tool 9, the suction port 15 sucks the chips generated by the processing and discharges them through the guide rod 11. During the rotation of the insert 13 along the annular groove 6, the top block 18 pushes the inner disk 10 to move back and forth along the guide rod 11, and uses the protrusion 20 to push the extrusion column 16 in the guide rod 11 to move back and forth radially toward the suction area, so that the rotation of the inner disk 10 is used to control the extrusion column 16 to compress the chips stuck in the suction area.
