Description

Technical Field

[0001] This utility model relates to the field of rivet processing technology, specifically to a chamfering device for standard rivet parts. Background Technology

[0002] Rivets are a common type of mechanical fastener, widely used in aerospace, automotive manufacturing, building steel structures, electronic equipment and other fields; standardized rivets must meet requirements for dimensional accuracy, surface finish and chamfering to ensure smooth assembly and connection strength;

[0003] A search of publication number CN115533016A reveals an automatic chamfering device for internal rivets of curved wire brushes. This technology discloses "an automatic chamfering device for internal rivets of curved wire brushes, comprising: a machine base; an internal rivet vibratory feeder mounted on the upper side of the machine base; and a chamfering assembly mounted on one side of the internal rivet vibratory feeder. The chamfering assembly includes a first fixed bracket and a punch moving plate. A chamfering die and a chamfering punch are respectively mounted on the first fixed bracket and the punch moving plate, and the chamfering die and the chamfering punch axially pass through..." The system includes an internal rivet positioning rod and an internal rivet guide rod. The internal rivet positioning rod is driven by a second cylinder to move axially, while the internal rivet guide rod and the punch moving plate are driven by a chamfering drive assembly to move axially. An internal rivet storage box is vertically positioned between the internal rivet vibratory plate and the chamfering assembly. A moving block is horizontally positioned on one side of the lower end of the internal rivet storage box and is driven by a first cylinder to move laterally. This technical solution has the technical effect of "solving the problems of existing internal rivet chamfering requiring manual operation and failing to guarantee safety and production efficiency."

[0004] In the current automated rivet processing, vibratory feeders are typically used for feeding. When rivets are fed from the vibratory feeder via the feeding track, adjacent rivets often come into close contact, making it difficult for the clamping device to accurately identify the center of a single rivet. This can lead to the misoperation of clamping multiple rivets at the same time. This condition not only affects the processing accuracy but also has an adverse impact on the stability of subsequent processes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a chamfering device for standard rivet parts. After the rivet is positioned by the material groove, it is separated into individual pieces by the material separating mechanism. Then, the positioning seat stably supports the rivet, while the chamfering head rotates to complete the precise chamfering process, ensuring the processing quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chamfering device for standard rivet parts, comprising a processing table and a rivet, wherein a chamfering mechanism is provided on the processing table for rivet processing, and the chamfering mechanism includes:

[0007] The limiting component includes a stand fixed in the middle of the top of the processing table, a material plate fixed at the upper end of the stand, a material groove opened inside the material plate, a support strip fixed on the inner wall of the material groove, a fixing plate fixed at the front end of the material plate, a first dual-axis cylinder installed at the front end of the fixing plate, a connecting plate fixed at the output end of the first dual-axis cylinder, and a material distribution head fixed at the rear end of the connecting plate.

[0008] A pick-and-place assembly is located on the top right side of the processing table and is used for picking up and placing rivets.

[0009] The machining component is located at the top rear of the machining table and is used for rivet chamfering.

[0010] Preferably, the pick-and-place assembly includes an electric slide fixed to the top right side of the processing table, a slide plate fixed on the slider of the electric slide plate, a base plate being longitudinally slidably mounted on the upper end of the slide plate, and a first cylinder being mounted on the bottom of the slide plate for driving the base plate to lift and lower.

[0011] Preferably, the pick-and-place assembly further includes a mounting bracket that is laterally slidably mounted on the upper end of the substrate. A second dual-axis cylinder is mounted on the top of the substrate and is used to drive the mounting bracket to move. A finger cylinder is mounted on the upper end of the mounting bracket. Both grippers of the finger cylinder are fixed with grippers, and the grippers are provided with gripping grooves.

[0012] Preferably, the processing assembly includes a bracket fixed to the rear end of the top of the processing table, a vertical frame fixed to the top of the bracket, a slide rail slidably installed inside the vertical frame, a second cylinder installed on the top of the vertical frame for driving the slide rail to lift and lower, a motor installed at the bottom of the slide rail, and a chamfering head fixed to the output end of the motor.

[0015] Beneficial effects

[0016] This invention provides a chamfering device for standard rivet parts. Compared with the prior art, it has the following advantages:

[0017] 1. When a batch of rivets is fed into the material slot in the material plate, the rivet head is supported by the support bar, so that the rivet shank is in a drooping state. Then, the connecting plate is driven by the first dual-shaft cylinder to drive the material distribution head through the rightmost rivet and the rivet adjacent to it, thereby separating the rightmost rivet from the other rivets, which facilitates the accurate gripping of subsequent rivets.

[0018] 2. The output end of the third cylinder drives the positioning seat to lift the rivet upward, counteracting the axial force during chamfering and preventing the rivet shank from bending; at the same time, the second cylinder drives the slide to move the chamfering head on the motor downward, and the motor drives the chamfering head to rotate, thereby performing chamfering on the rivet below.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 6This utility model provides a technical solution: a chamfering device for standard rivet parts, including a processing table 1 and rivets 3. The processing table 1 is provided with a chamfering mechanism 2 for processing rivets 3. The chamfering mechanism 2 includes:

[0028] The limiting component 21 includes a stand 211 fixed in the middle of the top of the processing table 1, a material plate 212 fixed at the upper end of the stand 211, a material groove 213 opened inside the material plate 212, a support strip 214 fixed on the inner wall of the material groove 213, a fixing plate 215 fixed at the front end of the material plate 212, a first dual-axis cylinder 216 installed at the front end of the fixing plate 215, a connecting plate 217 fixed at the output end of the first dual-axis cylinder 216, and a material distribution head 218 fixed at the rear end of the connecting plate 217.

[0029] The pick-and-place assembly 22 is located on the top right side of the processing table 1 and is used for picking up and placing rivets 3.

[0030] The processing component 23 is located at the top rear of the processing table 1 and is used for chamfering the rivet 3.

[0031] In this embodiment, when a batch of rivets 3 are fed into the material groove 213 in the material plate 212, the head of the rivet 3 is supported by the support bar 214, so that the rivet shank is in a drooping state. Then, the connecting plate 217 is driven by the first dual-shaft cylinder 216 to drive the material distribution head 218 to pass through the rightmost rivet 3 and the rivet 3 adjacent to it, thereby separating the rightmost rivet 3 from the other rivets 3, which facilitates the accurate gripping of the subsequent rivets 3.

[0032] Specifically, the pick-and-place assembly 22 includes an electric slide 221 fixed on the top right side of the processing table 1. A slide plate 222 is fixed on the slider of the electric slide 221. A base plate 223 is longitudinally slidably mounted on the upper end of the slide plate 222. A first cylinder 224 is installed at the bottom of the slide plate 222 and is used to drive the base plate 223 to rise and fall.

[0033] Specifically, the pick-and-place assembly 22 also includes a mounting bracket 225 that is laterally slidably mounted on the upper end of the substrate 223. A second dual-axis cylinder 226 is mounted on the top of the substrate 223 and is used to drive the mounting bracket 225 to move. A finger cylinder 227 is mounted on the upper end of the mounting bracket 225. Both grippers of the finger cylinder 227 are fixed with chucks 228, and the chucks 228 are provided with chuck grooves 229.

[0034] In this embodiment, the finger cylinder 227 drives the chuck 228 to cooperate with the clamping groove 229 to automatically clamp the rivet 3. The first cylinder 224 and the second dual-axis cylinder 226 can control the longitudinal and lateral movement of the clamped rivet 3 respectively.

[0035] Specifically, the processing component 23 includes a bracket 231 fixed to the rear end of the top of the processing table 1. A vertical frame 232 is fixed to the top of the bracket 231. A slide 233 is longitudinally slidably installed inside the vertical frame 232. A second cylinder 234 is installed on the top of the vertical frame 232 and is used to drive the slide 233 to rise and fall. A motor 235 is installed at the bottom of the slide 233. A chamfer head 236 is fixed to the output end of the motor 235.

[0036] In this embodiment, the second cylinder 234 drives the slide 233 to move the chamfering head 236 on the motor 235 downward, and at the same time the motor 235 drives the chamfering head 236 to rotate, thereby performing chamfering on the rivet 3 below.

[0037] Specifically, the processing component 23 also includes a mounting plate 237 fixed inside the bracket 231. A third cylinder 238 is mounted on the bottom of the mounting plate 237, and a positioning seat 239 is rotatably mounted on the output end of the third cylinder 238.

[0038] In this embodiment, when the rivet 3 held by the chuck 228 is delivered directly below the chamfering head 236, the positioning seat 239 is driven upward by the output end of the third cylinder 238 to support the rivet 3, thereby counteracting the axial force during chamfering and preventing the rivet shank from bending.

[0039] Specifically, a vibrating disc 24 and a straight vibrator 25 are installed on the top left side of the processing table 1. A slide 26 is installed between the discharge port of the vibrating disc 24 and the upper end of the straight vibrator 25, and the right end of the slide 26 is fixed to the material plate 212. A collection box 27 is placed in front of the top of the processing table 1.

[0040] In this embodiment, the rivet 3 is fed into the material plate 212 through the slide 26 by the vibrating disc 24 in conjunction with the direct vibrator 25.

[0041] The working principle and usage process of this utility model are as follows: First, the rivets 3 are fed into the material plate 212 through the slide 26 by the vibrating plate 24 and the direct vibrator 25. When a batch of rivets 3 are fed into the material groove 213 in the material plate 212, the head of the rivets 3 is supported by the support strip 214, so that the rivet shank is in a drooping state. Then, the connecting plate 217 is driven by the first dual-shaft cylinder 216 to drive the material distribution head 218 to pass through the rightmost rivet 3 and the rivets 3 adjacent to it, thereby separating the rightmost rivet 3 from the other rivets 3.

[0042] Then, the finger cylinder 227 drives the chuck 228 to cooperate with the clamping groove 229 to automatically clamp the rivet 3. The first cylinder 224 and the second dual-axis cylinder 226 can control the longitudinal and lateral movement of the clamped rivet 3 respectively, thereby sending the rivet 3 clamped by the chuck 228 directly below the chamfer head 236.

[0043] Finally, the output end of the third cylinder 238 drives the positioning seat 239 to lift the rivet 3 upward, counteracting the axial force during chamfering and preventing the rivet shank from bending; at the same time, the second cylinder 234 drives the slide 233 to move the chamfering head 236 on the motor 235 downward, and the motor 235 drives the chamfering head 236 to rotate, thereby performing chamfering on the rivet 3 below.
