[0001] This utility model relates to the field of machine tool technology, and in particular to a steerable cutting tool device for a shaper. Background Technology

[0002] A shaper is a machine tool used for metal cutting, primarily for planing flat surfaces, shaped surfaces, grooves, and straight contours of small to medium-sized workpieces. During operation, the shaper uses the reciprocating linear motion of the ram to drive the cutting tool to cut the material. This process generates significant cutting heat in the cutting tool, reducing its lifespan. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where heat accumulation from cutting tool marks leads to reduced service life, and to propose a steerable cutting tool device for a shaper.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Preferably, the sleeve is a regular hexagonal sleeve.

[0007] Preferably, a plurality of pins are installed through the sleeve, the pins are slidably engaged with the sleeve, and one end of the pin extends slidably into the short shaft to lock the short shaft.

[0008] Preferably, a circular ring is rotatably mounted on the baffle, and a plurality of arc-shaped guide grooves are fixedly connected to the inner wall of the ring. The end of the pin is provided with a protrusion, which slides in the guide groove.

[0009] Preferably, a connecting pipe is fixedly connected to the outer wall of the ring, and a return spring is fixed to the bottom of the mounting plate, with one end of the return spring fixedly connected to the outer wall of the connecting pipe.

[0010] Preferably, a ring gear is fixedly connected to the inner wall of the connecting pipe, and a second incomplete gear is fixedly connected to the output shaft of the motor, the second incomplete gear being matched with the ring gear.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 The planer's steerable cutting device includes a bed 1, a ram 2 that slides on the top of the bed 1, a lifting structure 4 at the end of the ram 2 for adjusting the height of the mounting plate 3, a baffle 6 fixedly connected to the mounting plate 3, a regular hexagonal sleeve 7 that passes through the baffle 6 and is fixedly connected to the baffle 6, a short shaft 8 that is rotatably installed inside the sleeve 7, a cutter head 5 fixedly connected to one end of the short shaft 8 and a driven gear 14 fixedly connected to the other end, multiple planing blades 501 distributed circumferentially on the cutter head 5, a motor 18 fixedly connected to the mounting plate 3, a first incomplete gear 15 fixedly connected to the output shaft of the motor 18, and the first incomplete gear 15 matching the driven gear 14.

[0024] The bed 1 drives the slide 2 to reciprocate linearly, causing the planer 501 on the cutter head 5 to move back and forth, thereby causing the planer 501 to cut the material.

[0025] During one motion cycle of the slide ram 2, the motor 18 drives the first incomplete gear 15 to rotate one revolution. The first incomplete gear 15 rotates one revolution, which drives the driven gear 14 to rotate 60 degrees. The driven gear 14 rotates 60 degrees, which drives the cutter head 5 to rotate 60 degrees through the short shaft 8. After the cutter head 5 rotates, it will replace the planer blade 501 to prevent the single planer blade 501 from being in a high-temperature state for a long time due to cutting heat, thus extending the service life of the planer blade 501.

[0026] like Figure 4 and Figure 9 As shown, multiple pins 13 are installed through the sleeve 7. The pins 13 slide with the sleeve 7, and one end of the pin 13 slides into the inside of the short shaft 8 to lock the short shaft 8.

[0027] Each time the planer blade 501 is replaced, the pin 13 will separate from the short shaft 8. After the planer blade 501 is replaced, the pin 13 will be reinserted into the short shaft 8 to lock the short shaft 8 and ensure that the short shaft 8 will not deflect accidentally.

[0028] like Figures 7-9 As shown, a circular ring 11 is rotatably mounted on the baffle 6. Multiple arc-shaped guide grooves 12 are fixed to the inner wall of the ring 11. The end of the pin 13 is provided with a protrusion, which slides in the guide groove 12.

[0029] When the ring 11 rotates, it will drive the guide groove 12 to rotate. The rotation of the guide groove 12 will drive the pin 13 to slide on the sleeve 7, thereby controlling whether the pin 13 locks the short shaft 8.

[0030] like Figures 4-8 As shown, a connecting pipe 10 is fixed to the outer wall of the ring 11, a return spring 9 is fixed to the bottom of the mounting plate 3, one end of the return spring 9 is fixed to the outer wall of the connecting pipe 10, a ring gear 16 is fixed to the inner wall of the connecting pipe 10, and a second incomplete gear 17 is fixed to the output shaft of the motor 18. The second incomplete gear 17 matches the ring gear 16.

[0031] When the motor 18 rotates, it will drive the second incomplete gear 17 to rotate. The rotation of the second incomplete gear 17 will drive the ring gear 16 to rotate. The ring gear 16 drives the ring member 10 to rotate through the connecting pipe 10, thereby controlling the pin 13 through the rotation of the ring member 10.

[0032] After the second incomplete gear 17 disengages from the ring gear 16, the return spring 9 will drive the connecting pipe 10 to reverse and reset, thereby resetting the pin 13 through the reverse reset of the connecting pipe 10.

[0033] Workflow:

[0034] The bed 1 drives the slide 2 to reciprocate linearly, causing the planer 501 on the cutter head 5 to move back and forth, thereby causing the planer 501 to cut the material.

[0035] During one motion cycle of the slide 2, the output shaft of the motor 18 rotates one revolution:

[0036] During the rotation of the motor 18, the second incomplete gear 17 first drives the ring gear 16 to rotate. The rotation of the ring gear 16 drives the ring member 11 to rotate through the connecting pipe 10. When the ring member 11 rotates, it will drive the guide groove 12 to rotate. The rotation of the guide groove 12 will drive the pin 13 to slide on the sleeve 7, so that the pin 13 is pulled out from the short shaft 8, allowing the short shaft 8 to enter a freely rotatable state.

[0037] When the short shaft 8 is in a freely rotatable state, the first incomplete gear 15 rotates once to drive the driven gear 14 to rotate. The driven gear 14 will drive the cutter head 5 to rotate through the short shaft 8. After the cutter head 5 rotates, it will replace the planer 501 to prevent the single planer 501 from being in a high-temperature state for a long time due to cutting heat, thus extending the service life of the planer 501.

[0038] After the planer 501 is replaced, the first incomplete gear 15 separates from the driven gear 14, and then the second incomplete gear 17 separates from the ring gear 16. After the second incomplete gear 17 separates from the ring gear 16, the return spring 9 will drive the connecting tube 10 to reverse and reset. The reverse reset of the connecting tube 10 will reset the pin 13, allowing the pin 13 to re-insert into the short shaft 8 and lock the short shaft 8.

[0039] Compared with the prior art, this application drives the cutter head 5 to rotate via the short shaft 8 to replace the planer cutter 501 that performs cutting work, thereby preventing a single planer cutter 501 from being in a high-temperature state for a long time due to cutting heat and extending the service life of the planer cutter 501.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
