[0020] In order to make the purpose, features and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present utility model.

[0021] See Figures 1 to 2 , the embodiment of the present utility model provides a tool device for cage machining, which is characterized in that it includes:

The even number of mounting seats 201 are symmetrically distributed at both ends of the machining part 2. The mounting seats 201 arranged at both ends of the machining part 2 are inclined towards the middle of the machining part 2. The tops of two oppositely arranged mounting seats 201 form a "V" - shaped structure;

[0023] A tool bit 3, the tool bit 3 is a cylindrical tool bit 3, and the number of the tool bits 3 is multiple. The tool bits 3 are detachably arranged in the mounting seats 201.

[0024] The embodiment of the present utility model provides a tool device for cage machining, including: a tool rest 1 and a tool bit 3; the tops of two oppositely arranged mounting seats 201 form a "V" - shaped structure; the tool bit 3 is a cylindrical tool bit 3, and the tool bits 3 are detachably arranged in the mounting seats 201. The cage is integrally in a ring - shaped body. When machining the outer side of the cage, the tops of two oppositely arranged mounting seats 201 form a "V" - shaped structure. The cooperation of two oppositely arranged mounting seats 201 can play an auxiliary alignment effect, which is convenient for the operator to adjust the relative position of the tool device and the workpiece, improves the operation convenience, and improves the running stability, thereby improving the machining accuracy of the workpiece; the tool bit 3 is a cylindrical tool bit 3, and the contact surface with the workpiece is an arc surface, the number of contact points increases, further improving the running stability, and thereby further improving the machining accuracy of the workpiece.

[0025] In a further feasible embodiment of the present embodiment, a fixing portion 202, an elastic clamping portion 203, and a locking member 204 are provided on the mounting base 201. The fixing portion 202 and the elastic clamping portion 203 cooperate to form a clamping groove 205 for accommodating the cutter head 3. The locking member 204 can drive the elastic clamping portion 203 to elastically deform, so that the end of the elastic clamping portion 203 moves towards the end of the fixing portion 202 to reduce the width of the clamping groove 205.

[0026] In this embodiment, a fixing portion 202, an elastic clamping portion 203, and a locking member 204 are provided on the mounting base 201. When installing the cutter head 3, place the cutter head 3 into the clamping groove 205. The locking member 204 drives the elastic clamping portion 203 to elastically deform, so that the end of the elastic clamping portion 203 moves towards the end of the fixing portion 202 to reduce the width of the clamping groove 205, thereby clamping the cutter head 3 and completing the installation of the cutter head 3. When the cutter head 3 needs to be replaced, loosen the locking member 204. The elastic clamping portion 203 resets under its own elastic force, so that the end of the elastic clamping portion 203 moves away from the end of the fixing portion 202 to increase the width of the clamping groove 205, thereby facilitating the operator to remove the cutter head 3 and completing the replacement of the cutter head 3. The structure of the mounting base 201 is simple, which is convenient for the operator to disassemble and assemble the cutter head 3, thus improving the production efficiency.

[0027] In a further feasible embodiment of the present embodiment, a locking screw hole 206 is provided on the fixing portion 202, a locking hole 207 is provided on the elastic clamping portion 203, the positions of the locking screw hole 206 and the locking hole 207 correspond to each other, and the locking member 204 is a locking bolt inserted into the locking screw hole 206 and the locking hole 207.

[0028] In this embodiment, the locking member 204 is a locking bolt inserted into the locking screw hole 206 and the locking hole 207. The locking bolt is threadedly connected to the locking screw hole 206. Tightening the locking bolt can make the elastic clamping portion 203 elastically deform, so that the end of the elastic clamping portion 203 moves towards the end of the fixing portion 202 to reduce the width of the clamping groove 205, thereby clamping the cutter head 3. Loosening the locking bolt can make the elastic clamping portion 203 reset under its own elastic force, so that the end of the elastic clamping portion 203 moves away from the end of the fixing portion 202 to increase the width of the clamping groove 205, thereby facilitating the operator to remove the cutter head 3. The structure is simple, which is further convenient for the operator to disassemble and assemble the cutter head 3, thus further improving the production efficiency.

[0029] In a further implementable manner of this embodiment, a first deformation groove 208 is provided between the elastic clamping portion 203 and the fixing portion 202.

[0030] In this embodiment, the bottom of the elastic clamping portion 203 and the bottom of the fixing portion 202 are integrally provided. A first deformation groove 208 is provided between the elastic clamping portion 203 and the fixing portion 202, so as to ensure that the elastic clamping portion 203 can elastically deform relative to the fixing portion 202, and the structure is simple and reliable, thereby effectively improving the connection strength between the elastic clamping portion 203 and the fixing portion 202, avoiding faults of the tool rest 1, further improving the operation stability, and further improving the machining accuracy of the workpiece.

[0031] In a further implementable manner of this embodiment, an arc surface 209 is provided at the top of the fixing portion 202, and an arc surface 209 is provided at the top of the elastic clamping portion 203.

[0032] In this embodiment, the arc surfaces 209 at the top of the fixing portion 202 and the top of the elastic clamping portion 203 correspond to the outer side surface of the tool head 3. When the tool head 3 is installed in the clamping groove 205, the arc surfaces 209 at the top of the fixing portion 202 and the top of the elastic clamping portion 203 are in contact with the outer side surface of the tool head 3, improving the connection strength between the tool head 3 and the mounting seat 201, further improving the operation stability, and further improving the machining accuracy of the workpiece.

[0033] In a further implementable manner of this embodiment, the number of the mounting seats 201 is four. Two relatively arranged mounting seats 201 are provided on the first side of the machining portion 2, and two relatively arranged mounting seats 201 are provided on the second side of the machining portion 2.

[0035] In a further implementable manner of this embodiment, a second deformation groove 210 is provided between two relatively arranged mounting seats 201.

[0036] In this embodiment, the bottoms of the two oppositely arranged mounting seats 201 are integrally arranged, and a second deformation groove 210 is formed between the two oppositely arranged mounting seats 201, so as to ensure that the elastic clamping portion 203 can elastically deform relative to the fixed portion 202, and the structure is simple and reliable, so that the strength of the tool rest 1 can be effectively improved, so as to avoid faults of the tool rest 1, further improve the operation stability, and further improve the machining accuracy of the workpiece.

[0037] In a further feasible implementation manner of this embodiment, the included angle between the axes of the two oppositely arranged tool heads 3 is 140°.

[0038] In this embodiment, the tool head 3 is installed in the mounting rack, and the included angle between the axes of the two tool heads 3 installed in the two oppositely arranged mounting racks is 140°. If the included angle between the axes of the two tool heads 3 is too small, during machining, the position of the tool rest 1 between the two tool heads 3 needs to bear a large load, which is likely to affect the service life of the tool rest 1 and the operation stability, thus affecting the machining accuracy of the workpiece; if the included angle between the axes of the two tool heads 3 is too small, during machining, the effect of auxiliary alignment cannot be effectively achieved, thus the operation stability cannot be effectively improved, and the machining accuracy of the workpiece is affected.
