[0046] At present, small-module internal gears are usually processed by gear shaping machines. After the gear shaping is completed, edges and burrs are inevitably left at the entry and exit points of the internal gear. At present, internal gears are generally chamfered and deburred by hand, which is not only inefficient but also difficult to clean thoroughly.

[0047] In order to solve the problem of low efficiency of manual chamfering and deburring, the present application proposes an internal gear chamfering and deburring device.

[0048] Please also refer to Figure 1 , Figure 3 , Figure 5 and Figure 8 The internal gear chamfering and deburring device 100 includes a workpiece clamping assembly 10, a tool clamping assembly 20 and a tool 30. The workpiece clamping assembly 10 reciprocates in a first direction Z, and the tool clamping assembly 20 reciprocates in a second direction Y, and the first direction Z intersects with the second direction Y; the workpiece clamping assembly 10 includes a first clamping structure 11 and a first driving mechanism 12, the first clamping structure 11 is used to clamp the internal gear 200, and the first driving mechanism 12 is used to drive the first clamping structure 11 to rotate around the second direction Y; the tool clamping assembly 20 includes a second clamping structure 21 and a second driving mechanism 22, the tool 30 is clamped on the second clamping structure 21, and the second driving mechanism 22 is used to drive the second clamping structure 21 to rotate around the second direction Y; a plurality of cutting edges 311 are provided on the end face of the tool 30 away from the second driving mechanism 22, and the plurality of cutting edges 311 extend along the radial direction of the tool 30 and are arranged at intervals along the circumference of the tool 30.

[0049] Optionally, the first direction Z intersects the second direction Y perpendicularly, that is, the angle between the first direction Z and the second direction Y is 90°, for example, the first direction Z is a vertical direction, and the second direction Y is a horizontal direction.

[0050] The workpiece clamping assembly 10 reciprocates in a first direction Z, and the tool clamping assembly 20 reciprocates in a second direction Y, that is, the moving direction of the workpiece clamping assembly 10 is perpendicular to the moving direction of the tool clamping assembly 20 .

[0051] After the first clamping structure 11 clamps the internal gear 200 , when the first driving mechanism 12 drives the first clamping structure 11 to rotate around the second direction Y, the internal gear 200 rotates around the second direction Y along with the first clamping structure 11 .

[0052] Optionally, the first driving mechanism 12 includes a first motor 121 and a transmission mechanism, and the first motor 121 drives the first clamping structure 11 to rotate through the transmission mechanism; wherein the transmission mechanism may be a worm gear mechanism, a gear mechanism, etc.

[0053] After the second clamping structure 21 clamps the tool 30 , when the second driving mechanism 22 drives the second clamping structure 21 to rotate around the second direction Y, the tool 30 rotates around the second direction Y along with the second clamping structure 21 .

[0054] It can be understood that the second driving mechanism 22 is a second motor, which directly drives the second clamping structure 21 to rotate; or, the second driving mechanism 22 includes a second motor and a transmission mechanism, and the second motor drives the second clamping structure 21 to rotate through the transmission mechanism; wherein the transmission mechanism can be a worm gear mechanism, a gear mechanism, etc.

[0055] The end face of the tool 30 facing away from the second drive mechanism 22 refers to the end face of the tool 30 facing the internal gear 200, and optionally, the end face is a plane. The radial direction of the tool 30 refers to the direction extending from the center to the edge of the tool 30; the circumferential direction of the tool 30 refers to the circumferential direction of the tool 30. Optionally, the tool 30 is a milling cutter.

[0056] It should be noted that the rotation speed of the internal gear 200 and the rotation speed of the tool 30 need to be determined based on the number of teeth of the internal gear 200 and the number of cutting edges 311 of the tool 30. For example, if the number of teeth of the internal gear 200 is twice the number of cutting edges 311, then the rotation speed of the tool 30 is twice the rotation speed of the internal gear 200.

[0057] The internal gear chamfering and deburring device 100 provided in the embodiment of the present application comprises a workpiece clamping assembly 10, a tool clamping assembly 20 and a tool 30, wherein the tool 30 is clamped on the tool clamping assembly 20. During operation, the internal gear 200 is first clamped on the workpiece clamping assembly 10; then the tool clamping assembly 20 moves along the second direction Y to extend the tool 30 into the internal gear 200 for tool alignment, such as Fig. 9As shown, the outer end 3111 of the tip of the cutting edge 311 is aligned with the sharp corner 201 on one side of the tooth top of the internal gear 200; then the first clamping structure 11 and the second clamping structure 21 are respectively driven by the first drive mechanism 12 and the second drive mechanism 22 to rotate at a set speed, and the workpiece clamping assembly 10 moves along the first direction Z to achieve the cutting process of the tool 30 on the tooth top of each tooth on the internal gear 200 to the tooth root; after the above-mentioned cutting process is completed, the first drive mechanism 12 and the second drive mechanism 22 stop working, and the tool is re-aligned, so that the outer end 3111 of the tip of the cutting edge 311 is aligned with the sharp corner 201 on the other side of the tooth top of the internal gear 200; thereafter, the first clamping structure 11 and the second clamping structure 21 are respectively driven by the first drive mechanism 12 and the second drive mechanism 22 to rotate at a set speed, and the workpiece clamping assembly 10 moves along the first direction Z to achieve the cutting process of the tool 30 on the other side of the tooth top of each tooth on the internal gear 200 to the tooth root; finally, the cutting process on both sides of each tooth is completed. The internal gear chamfering and deburring device 100 removes burrs from the end of the internal gear 200 while chamfering the end of the internal gear 200, thereby improving processing efficiency and optimizing product quality.

[0058] Please also refer to Figure 2 and Figure 3 In some embodiments, the workpiece clamping assembly 10 also includes a first fixed seat 13, the first clamping structure 11 is rotatably installed in the first fixed seat 13 around the second direction Y, the first driving mechanism 12 includes a first motor 121, a worm gear 123 and a worm 122, the first motor 121 is installed on the first fixed seat 13, the worm 122 is connected to the output end of the first motor 121, and the worm gear 123 is installed on the first clamping structure 11 and meshes with the worm 122.

[0059] The first fixed seat 13 is used to install the first clamping structure 11 and the first driving mechanism 12. The first fixed seat 13 reciprocates along the first direction Z, thereby realizing the reciprocating movement of the first clamping structure 11 and the first driving mechanism 12 along the first direction Z. Specifically, the first fixed seat 13 is fixed on the second slide 80, and the frame 40 is provided with a first slide rail 41 extending along the first direction Z. The fifth motor 90 drives the second slide 80 to slide on the first slide rail 41 through a screw nut mechanism to realize the reciprocating movement of the first fixed seat 13 along the first direction Z; wherein, at least two first slide rails 41 are arranged at intervals along the second direction Y to ensure the stability of the first fixed seat 13 when moving. Of course, the second slide 80 may not be provided, and the first fixed seat 13 slides directly on the first slide rail 41.

[0060] Optionally, the worm 122 extends along the first direction Z, and the first motor 121 is located above the first fixing seat 13 . This design ensures that the first motor 121 will not interfere with the tool clamping assembly 20 .

[0061] In other embodiments, the first driving mechanism 12 includes a first motor 121, a driving gear and a driven gear, the driving gear is connected to the first motor 121, the driven gear is installed on the first clamping structure 11 and meshes with the driving gear, at this time, the first motor 121 is on one side of the first fixed seat 13 in the second direction Y.

[0062] Please also refer to Figure 3 and Figure 4 In some embodiments, the first clamping structure 11 includes a mounting sleeve 111 and two pressing rings 112. The inner cavity of the mounting sleeve 111 is used to install the internal gear 200. The two pressing rings 112 are respectively fixed at the axial ends of the mounting sleeve 111 to press the internal gear 200 into the mounting sleeve 111; the worm gear 123 is sleeved on the mounting sleeve 111.

[0063] It can be understood that the installation sleeve 111 and the internal gear 200 are transitionally fitted or clearance-fitted to facilitate the internal gear 200 to be installed in the installation sleeve 111 .

[0064] Optionally, the length of the mounting sleeve 111 is less than or equal to the length of the internal gear 200; during installation, the internal gear 200 is first installed into the mounting sleeve 111, and then the two pressure rings 112 are respectively fixed at the axial ends of the mounting sleeve 111. At this time, the two pressure rings 112 limit the axial ends of the internal gear 200 to fix the internal gear 200 in the mounting sleeve 111.

[0065] There are many ways to fix the pressure ring 112 on the installation sleeve 111. For example, the pressure ring 112 can be fixed on the installation sleeve 111 by means of snap connection, fastener connection, threaded connection, etc.

[0066] The worm gear 123 is fixed on the mounting sleeve 111 . It is understandable that the worm gear 123 can be fixed on the mounting sleeve 111 by welding, or the worm gear 123 can be interference fitted on the mounting sleeve 111 .

[0067] The internal gear 200 is pressed into the mounting sleeve 111 by the pressing ring 112 , which will not cause damage to the surface of the internal gear 200 , thereby ensuring the surface quality of the internal gear 200 .

[0068] In other embodiments, only one pressure ring 112 is provided, and a protrusion extending inward is provided at one end of the mounting sleeve 111. Optionally, the protrusion is an annular protrusion, which can limit one end of the internal gear 200, and the pressure ring 112 limits the other end of the internal gear 200 to fix the internal gear 200 in the mounting sleeve 111.

[0069] In some embodiments, two pressure rings 112 are respectively threadedly connected to two ends of the mounting sleeve 111 .

[0070] Specifically, annular steps are respectively provided at both ends of the installation sleeve 111 , and external threads are provided on the annular steps. The pressure ring 112 has internal threads, and the pressure ring 112 is threadedly connected to the annular steps to be fixed on the installation sleeve 111 .

[0071] By threading the pressing ring 112 to the end of the mounting sleeve 111 , it is convenient to disassemble and assemble the pressing ring 112 , thereby facilitating the disassembly and assembly of the internal gear 200 , thereby improving the processing efficiency.

[0072] In other embodiments, one of the pressing rings 112 may be threadedly connected to the mounting sleeve 111 , and the other pressing ring 112 may be connected to the mounting sleeve 111 by means of snap connection, fastener connection, or the like.

[0073] In other embodiments, based on the situation that two pressure rings 112 are threadedly connected to the two ends of the installation sleeve 111, multiple slits can be processed at the two ends of the installation sleeve 111, so that the two ends of the installation sleeve 111 are in a petal shape; when the pressure ring 112 is screwed on the end of the installation sleeve 111, the pressure ring 112 will press the end of the installation sleeve 111 along the radial direction of the installation sleeve 111, so that the end of the installation sleeve 111 presses the end of the internal gear 200, so that the internal gear 200 is fixed in the installation sleeve 111. The internal thread of the pressure ring 112 is a tapered thread.

[0074] In some embodiments, a bearing 14 is disposed between the mounting sleeve 111 and the first fixing seat 13 .

[0075] Yes, the bearing 14 can be sleeved and fixed on the mounting sleeve 111 , or can be fixed in the first fixing seat 13 .

[0076] By adopting the above technical solution, the friction force when the installation sleeve 111 rotates in the first fixing seat 13 can be reduced, the service life of the installation sleeve 111 can be increased, and the energy loss can be reduced.

[0077] In other embodiments, a self-lubricating sleeve, such as a self-lubricating copper sleeve, a nylon sleeve, etc., is provided between the installation sleeve 111 and the first fixing seat 13 , wherein the self-lubricating sleeve can be sleeved and fixed on the installation sleeve 111 , or fixed in the first fixing seat 13 .

[0078] In some embodiments, bearings 14 are respectively disposed on both sides of the worm gear 123 in the second direction Y.

[0079] The number of bearings 14 on both sides of the worm wheel 123 may be the same or different. When the number of bearings 14 on both sides of the worm wheel 123 is the same, one, two or more bearings 14 may be provided on both sides of the worm wheel 123; when the number of bearings 14 on both sides of the worm wheel 123 is different, one side of the worm wheel 123 may be provided with one bearing 14, and the other side of the worm wheel 123 may be provided with two or more bearings 14.

[0080] By adopting the above technical solution, when the installation sleeve 111 rotates in the first fixing seat 13, not only the friction force can be reduced, but also the force uniformity of the installation sleeve 111 can be ensured, thereby improving the stability of the installation sleeve 111 when rotating in the first fixing seat 13.

[0081] Please refer to Figure 1 In some embodiments, two tool clamping assemblies 20 are provided, and the two tool clamping assemblies 20 are respectively arranged on both sides of the workpiece clamping assembly 10 along the second direction Y.

[0082] By adopting the above technical solution, after the two tools 30 are respectively installed on the two tool clamping assemblies 20, the two tool clamping assemblies 20 can simultaneously chamfer and deburr the two ends of the internal gear 200, thereby improving the processing efficiency.

[0083] In other embodiments, one tool clamping assembly 20 may be provided, and after the tool clamping assembly 20 performs chamfering and deburring on one end of the internal gear 200 , the internal gear 200 is re-clamped, and then the other end of the internal gear 200 is chamfered and deburred.
