Specific Embodiments
[0025] The following explains and illustrates the technical solutions of the embodiments of the present utility model in conjunction with the accompanying drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.
[0026] The following specifically describes a mechanical part chamfering device according to an embodiment of the present utility model in conjunction with the accompanying drawings.
[0027] For ease of understanding, please refer to Figures 1 to 6 Figures 1 to 6 , an embodiment of a mechanical part chamfering device provided by the present utility model includes a workbench 101, a fixed frame 102 is fixedly connected to the top of the workbench 101, a top plate 103 is fixedly connected above the fixed frame 102, a chamfering tool head assembly 2 is fixedly connected to one side of the fixed frame 102 and the top plate 103, a second hydraulic cylinder 301 is fixedly connected to one end of the fixed frame 102, a push plate 302 is fixedly connected to the end of the second hydraulic cylinder 301, and a clamping assembly 4 is arranged at the center of the top of the workbench 101;
[0028] The chamfering tool head assembly 2 includes two guide rails 201. One guide rail 201 is fixedly connected to the midline of the side of the fixed frame 102 close to the workbench 101, and the other guide rail 201 is fixedly connected to the bottom midline of the top plate 103. Sliding blocks 202 are slidably connected to both guide rails 201. A first hydraulic cylinder 203 is fixedly installed on each of the two sliding blocks 202. A motor housing 204 is fixedly connected to the end of each of the two first hydraulic cylinders 203. A first stepping motor 205 is fixedly installed at the center of the axis inside the motor housing 204. A rotating cutter disc 207 is fixedly connected to the output end of the first stepping motor 205. A plurality of cutter head motor housings 208 are fixedly installed at equal intervals around the axis at the bottom end of the rotating cutter disc 207. A magnetic adsorption electrode male head 206 is fixedly installed at the corresponding position of the center of the axis of the bottom of the motor housing 204 and the cutter head motor housing 208. One end of the magnetic adsorption electrode male head 206 is fixedly connected to a first cable 212. A magnetic adsorption electrode female head 209 is fixedly installed at the center of the axis of the top of each of the plurality of cutter head motor housings 208. One end of the magnetic adsorption electrode female head 209 is fixedly connected to a second cable 213. A cutter head motor 210 is fixedly installed inside each of the plurality of cutter head motor housings 208. The other end of the second cable 213 is fixedly connected to the input end of the cutter head motor 210. A chamfering cutter head 211 is fixedly connected to the output end of the cutter head motor 210. The two guide rails 201 are perpendicular to each other. The plurality of chamfering cutter heads 211 are C-angle cutter heads, external R-angle cutter heads, and internal R-angle cutter heads.
[0029] It should be noted that one of the first hydraulic cylinders 203 causes the other first hydraulic cylinder 203 connected to the motor housing 204 to move on the guide rail 201 under the action of the slider 202, so as to adjust the position of the motor housing 204 up, down, forward and backward. According to different chamfering requirements, the first stepping motor 205 is started to rotate the rotating cutter head 207 by 120° once, driving the three cutter head motor housings 208 at the bottom of the rotating cutter head 207 to switch positions with the corresponding chamfering cutter heads 211 to complete the switching of the required chamfering cutter heads 211. The magnetic attraction electrode female head 209 fixedly connected to the top of the cutter head motor housing 208 and the magnetic attraction electrode male head 206 at the bottom of the motor housing 204 have a conductive function. When the magnetic attraction electrode female head 209 contacts the magnetic attraction electrode male head 206, the first cable 212, the magnetic attraction electrode male head 206, the magnetic attraction electrode female head 209 and the second cable 213 form a circuit, so that the cutter head motor 210 fixedly installed in the corresponding cutter head motor housing 208 is powered on to start working, driving the chamfering cutter head 211 fixedly installed at the output end of the cutter head motor 210 to chamfer the parts. This design enables flexible adjustment in the face of different chamfering requirements for different parts, avoiding frequent replacement of the chamfering cutter head 211.
[0030] In some embodiments, as Figure 5 shown, the clamping assembly 4 includes a turntable 401, a first chute 402, a limiting plate 403, a knob 404, a lead screw 405, a first clamping plate 4061, a second clamping plate 4062, two groups of balls 407, a first rack 4081, a second rack 4082, a spur gear 409, a second chute 410 and a plurality of slide bars 411. The first chute 402 is opened at the top center of the turntable 401. The spur gear 409 is rotatably connected to the center of the first chute 402. The first rack 4081 is meshed and connected to the bottom of the spur gear 409. The second rack 4082 is meshed and connected to the top of the spur gear 409. The limiting plate 403 is fixedly connected to the top of the turntable 401. The lead screw 405 is arranged at the center of the limiting plate 403. The knob 404 is fixedly connected to one end of the lead screw 405. The first clamping plate 4061 and the second clamping plate 4062 are respectively fixedly connected to the tops of the first rack 4081 and the second rack 4082, and one side of the first clamping plate 4061 is rotatably connected to the other end of the lead screw 405. The two groups of balls 407 are respectively movably embedded in the corresponding side walls of the two first clamping plates 4061 and the second clamping plate 4062. The second chute 410 is opened at the side walls at both ends of the first chute 402. The plurality of slide bars 411 are respectively fixedly connected to both ends of the first rack 4081 and the second rack 4082, and the slide bars 411 are respectively slidably connected to the second chute 410.
[0031] It should be noted that the first chute 402 and the second chute 410 opened at the axis of the turntable 401 enable the first rack 4081 and the second rack 4082 to move in a specified direction under the limitation of the slide bar 411. The limiting plate 403 fixes the position of the lead screw 405. By rotating the knob 404 to control the translation of the lead screw 405, the position of the first clamping plate 4061 is changed. After the first clamping plate 4061 moves following the lead screw 405, it drives the first rack 4081 installed at the bottom to displace in the second chute 410 under the limitation of the slide bar 411. The movement of the first rack 4081 drives the spur gear 409 to rotate, causing the second rack 4082 to move in the second chute 410 under the limitation of the slide bar 411 following the rotation of the spur gear 409, driving the second clamping plate 4062 connected to the second rack 4082 to make a mirror image movement, completing the clamping and positioning operation of the required chamfered part. The second hydraulic cylinder 301 moves the push plate 302. Under the action of the push plate 302 and the ball 407, the required chamfered part starts to move along the first clamping plate 4061 and the second clamping plate 4062, and the required chamfered part completes a single-sided chamfer through the chamfering cutter head 211.
[0032] In some embodiments, as Figure 2 shown, a motor bracket 5 is fixedly connected to the bottom of the workbench 101, a second stepper motor 6 is fixedly installed on the top of the motor bracket 5, and the turntable 401 is fixedly connected to the output end of the second stepper motor 6.
[0033] It should be noted that after the single-sided chamfering is completed, the second hydraulic cylinder 301 and the push plate 302 are reset. The second stepper motor 6 fixedly connected to the bottom of the turntable 401 rotates 180°, so that the part is again located at one end of the push plate 302, and the other side of the part is chamfered, saving the repositioning operation of the part again, improving the degree of process automation, and accelerating the working efficiency.
[0034] The hydraulic cylinder and the stepper motor in the present utility model are well-known components and will not be elaborated here.
[0035] Working principle: When chamfering, first turn the knob 404 to control the translation of the screw 405 to change the position of the first clamping plate 4061. The first rack 4081 at the bottom of the first clamping plate 4061 cooperates with the spur gear 409 to move the second rack 4082, driving the second clamping plate 4062 to move in a mirror image, ensuring that the chamfered parts are always on the symmetrical axis of the first clamping plate 4061 and the second clamping plate 4062 when clamping and positioning. After the parts are fixed, the second hydraulic cylinder 301 moves the push plate 302 , the part to be chamfered begins to move along the first clamping plate 4061 and the second clamping plate 4062 under the action of the pushing plate 302 and the ball 407, and the part to be chamfered is completed by the chamfering cutter head 211. The second hydraulic cylinder 301 and the pushing plate 302 are reset, and the second stepping motor 6 is started to rotate the turntable 401 180 degrees, so that the part is turned over and positioned at one end of the pushing plate 302 again. The above pushing process is repeated to complete the chamfering work on both sides, which saves the operation of re-positioning the part, improves the degree of process automation, and speeds up work efficiency;
[0036] When different parts have different chamfering requirements, the No. 1 stepper motor 205 is started according to the requirements to make the rotating cutter disc 207 rotate 120° in a single time to replace the cutter head. The tops of the three cutter head motor compartments 208 are fixedly connected to the magnetic electrode female head 209, and the bottom of the motor compartment 204 is fixedly connected to the only magnetic electrode male head 206. When the fixedly connected magnetic electrode female head 209 contacts the magnetic electrode male head 206, the No. 1 cable 212 forms a loop with the magnetic electrode male head 206, the magnetic electrode female head 209 and the No. 2 cable 213, so that the cutter head motor 210 built into the corresponding cutter head motor compartment 208 is energized to drive the chamfering cutter head 211 to start working. This design allows flexible adjustment when facing different chamfering requirements of different parts, avoiding frequent replacement of the chamfering cutter head 211.
[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
