Description

Technical fields:

[0001] This utility model relates to the field of hardware processing technology, and specifically to a multi-axis automatic rapid chamfering device. Background technology:

[0002] Hardware parts often require drilling and chamfering. Drilling is commonly used to install fasteners such as bolts and screws, and threaded holes are used to connect and fix components; chamfering can remove sharp edges and burrs produced after machining, preventing scratches to operators or creating safety hazards.

[0003] Currently available molds can drill holes in metal parts. For example, Chinese utility model patent application CN210878720U discloses a metal processing drilling mold, which includes: a base platform with a bottom sloping groove on the top of the base platform. Conveyor belts are fixedly connected to the inner walls of both sides of the bottom sloping groove. A hydraulic telescopic rod is fixedly connected to the top of the base platform. A fixing plate is welded to the top of the hydraulic telescopic rod. A motor base is slidably connected to the bottom of the fixing plate. A motor is fixedly installed inside the motor base cavity. A mounting ring is welded to the motor's rotor. A twist drill is threaded into the mounting ring cavity. A second spring is sleeved on the outer wall of the twist drill. A fixing ring is welded to the bottom of the second spring. In this metal processing drilling mold, the fixing ring applies pressure to the workpiece to be drilled, and the second spring retracts, allowing the twist drill to reach the drilling position and drill. After drilling, the second spring extends with the hydraulic telescopic rod.

[0004] However, this existing metal processing drilling mold uses a retaining ring to pressurize and fix the workpiece, and a second spring retracts to allow the twist drill to reach the drilling position. When multiple parts on a single part need to be processed, multiple drilling operations are required, which is not only inefficient but also prone to omissions and poor processing quality. In addition, this technical solution can only perform drilling. Therefore, when punching and chamfering metal parts, two different sets of molds are generally required, and two different processes are needed to complete the operation. After the metal sheet is punched, it is manually transferred to another set of molds for chamfering. This operation method requires two different sets of molds, resulting in high equipment costs for enterprises. Furthermore, the manual transfer of workpieces between the two sets of molds not only leads to high labor intensity and labor costs for workers but also results in low processing efficiency, making it unable to meet the requirements of large-scale, batch production.

[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-axis automatic rapid chamfering device.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-axis automatic rapid chamfering device, comprising: a base plate, a drive cylinder disposed on the base plate, a product positioning mold disposed on the output shaft of the drive cylinder and capable of being raised and lowered accordingly, a multi-axis linkage mechanism disposed above the product positioning mold, a first positioning block and a second positioning block disposed at the lower end of the multi-axis linkage mechanism and used to abut against the product, and a pneumatic switch disposed on the base plate. The multi-axis linkage mechanism includes a linkage seat body, a gear set disposed in the linkage seat body, several chamfering shafts disposed on the linkage seat body and used for processing the product, and several chamfering shaft fixing blocks disposed on the linkage seat body and connected to the end of each chamfering shaft for positioning.

The linkage seat body has third guide holes and fourth guide holes on both sides for the first guide post and the second guide post to pass through, respectively; the third rotating gears are distributed around the second transmission gear.

[0010] Furthermore, in the above technical solution, the linkage seat body is provided with a first rotating shaft passing through the first transmission gear, and a first bearing is sleeved on the first rotating shaft; the linkage seat body is also provided with a second rotating shaft passing through the second transmission gear, and a second bearing is sleeved on the second rotating shaft; the linkage seat body is also provided with four third bearings, and the four third bearings are respectively sleeved on each chamfered rotating shaft.

[0011] Furthermore, in the above technical solution, the linkage seat body includes a seat for accommodating the gear set and a cover covering the seat.

[0012] Furthermore, in the above technical solution, there are four chamfering shafts, and correspondingly, there are also four third rotating gears. The four third rotating gears pass through each chamfering shaft to drive the chamfering shaft to rotate synchronously.

[0013] Furthermore, in the above technical solution, the chamfering shaft is cylindrical, and the lower end of the chamfering shaft is formed with a chamfering tip for chamfering the product.

[0015] Furthermore, in the above technical solution, the pneumatic switch includes a pneumatic base disposed on a base plate, a switch portion mounted on the pneumatic base, and a lever disposed on the switch portion in a swingable manner.

[0016] Furthermore, in the above technical solution, a loading channel for loading and unloading products is provided on one side of the product positioning mold.

[0017] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: This utility model changes the traditional method of requiring multiple processing steps for multi-hole parts. By driving a cylinder to lift and lower the product positioning mold, and using a multi-axis linkage mechanism to drive the chamfering shaft to rotate via a gear set, it quickly drills and chamfers the product on the positioning mold.

[0022] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0023] See Figures 1 to 4As shown, a multi-axis automatic rapid chamfering device includes: a base plate 1, a drive cylinder 2 mounted on the base plate 1, a product positioning mold 3 mounted on the output shaft of the drive cylinder 2 and capable of being raised and lowered accordingly, a multi-axis linkage mechanism 4 mounted above the product positioning mold 3, a first positioning block 5 and a second positioning block 6 mounted at the lower end of the multi-axis linkage mechanism 4 for contacting the product 10, and a pneumatic switch 7 mounted on the base plate 1. The multi-axis linkage mechanism 4 includes a linkage seat body 41, a gear set 42 mounted in the linkage seat body 41, several chamfering shafts 43 mounted on the linkage seat body 41 for processing the product 10, and several chamfering shaft fixing blocks 44 mounted on the linkage seat body 41 and connected to the end of each chamfering shaft 43 for positioning.

[0024] This invention changes the traditional method of multiple processing steps for multi-hole parts. By using a drive cylinder 2 to raise and lower the product positioning mold 3, and a multi-axis linkage mechanism 4 to rotate the chamfering shaft 43 via a gear set 42, the product 10 on the product positioning mold 3 is quickly drilled and chamfered. This effectively achieves simultaneous multi-hole processing within a limited space, significantly improving processing efficiency and quality. Furthermore, compared to existing structures, this invention utilizes the rotating chamfering shaft 43 to chamfer the perforated part of the product 10 without needing to change to another mold midway, effectively improving ease of use.

[0025] The base plate 1 is vertically provided with a first guide post 11 and a second guide post 12. The product positioning mold 3 has a first guide hole 31 on one side for the first guide post 11 to pass through, and a second guide hole 32 on the other side for the second guide post 12 to pass through, allowing the product positioning mold 3 to smoothly rise and fall along the first guide post 11 and the second guide hole 32. Here, by providing the first guide post 11 and the second guide post 12 on the base plate 1, and allowing the product positioning mold 3 to rise and fall along the first guide post 11 and the second guide hole 32, it is possible to effectively ensure that the product positioning mold 3 carries the product 10 smoothly upwards, so that the product 10 is accurately moved below the multi-axis linkage mechanism 4, significantly improving the processing accuracy.

[0026] The linkage seat body 41 includes a seat 415 for accommodating the gear set 42 and a cover 416 covering the seat 415.

[0027] The gear set 42 includes a first transmission gear 421 disposed within the linkage seat body 41, a second transmission gear 422 disposed within the linkage seat body 41 and meshing with the first transmission gear 421, and several third rotating gears 423 meshing with the second transmission gear 422 and used to drive the chamfered rotating shaft 43 to rotate. The linkage seat body 41 has third guide holes 413 and fourth guide holes 414 on both sides for the first guide post 11 and the second guide post 12 to pass through, respectively. The third rotating gears 423 are distributed around the second transmission gears 422. Here, in conjunction with... Figure 4 As shown, preferably, there are four third rotating gears 423. The multi-axis linkage mechanism 4 is driven by a gear set 42. The first transmission gear 421 is used to connect with an external drive mechanism and drives the second transmission gear 422 to rotate. Then, the second transmission gear 422 drives the third rotating gears 423 arranged around it to rotate, so as to achieve synchronous rotation of the four third rotating gears 423. In addition, it should be noted that the thickness of the second transmission gear 422 is greater than the thickness of the first transmission gear 421, and the thickness of the second transmission gear 422 is greater than the thickness of the third transmission gear 423. The second transmission gear 422 is located in the middle of the base 415, and the thicknesses of the first transmission gear 421 and the third rotating gears 423 are not meshed.

[0028] Preferably, there are four chamfering shafts 43, and correspondingly, there are also four third rotating gears 423. The four third rotating gears 423 pass through each chamfering shaft 43 to drive the chamfering shaft 43 to rotate synchronously.

[0029] The linkage seat body 41 is provided with a first rotating shaft 411 passing through the first transmission gear 421, and a first bearing 417 is sleeved on the first rotating shaft 411; the linkage seat body 41 is also provided with a second rotating shaft 412 passing through the second transmission gear 422, and a second bearing 418 is sleeved on the second rotating shaft 412; the linkage seat body 41 is also provided with four third bearings 410, which are respectively sleeved on each chamfered rotating shaft 43. Here, preferably, there are four third bearings 410, which are respectively sleeved on each chamfered rotating shaft 43, so that the chamfered rotating shaft 43 can rotate smoothly with the third transmission gear 423.

[0030] The chamfering shaft 43 is cylindrical, and its lower end is formed with a chamfering tip 431 for chamfering the product 10. Here, the chamfering tip 431 can rotate with the chamfering shaft 43 to chamfer the perforation of the product 10, without having to change to another set of molds to chamfer the product, effectively improving ease of use.

[0031] The first positioning block 5 is made of a soft material, and a first groove 51 is recessed on the first positioning block 5. The first groove 51 is V-shaped or inverted V-shaped. The second positioning block 6 is also made of a soft material, and a second groove 52 is recessed on the second positioning block 6. The second groove 52 is V-shaped or inverted V-shaped. Here, both the first positioning block 5 and the second positioning block 6 are made of soft materials to avoid hard contact between the non-processed parts of the product 10 and the multi-axis linkage mechanism 4, which could cause damage to the product's shape and effectively protect the appearance of the product 10.

[0032] The pneumatic switch 7 includes a pneumatic base 71 disposed on a base plate 1, a switch part 72 mounted on the pneumatic base 71, and a lever 73 disposed on the switch part 72 in a swingable manner.

[0033] The product positioning mold 3 has a loading channel 30 on one side for loading and unloading the product 10. When loading, the product 10 can be placed on the loading channel 30 and then moved along it to the product positioning mold 3 for processing. When unloading, the processed product 10 can be moved directly out of the product positioning mold 3 along the loading channel 30 and then taken out.

[0034] In summary, this invention changes the traditional method of multiple processing steps for multi-hole parts. By using a drive cylinder 2 to lift and lower the product positioning mold 3, and a multi-axis linkage mechanism 4 to rotate the chamfering shaft 43 via a gear set 42, the product 10 on the product positioning mold 3 is rapidly drilled and chamfered. This effectively achieves simultaneous multi-hole processing within a limited space, significantly improving processing efficiency and quality. Furthermore, compared to existing structures, this invention utilizes the rotating chamfering shaft 43 to chamfer the perforated parts of the product 10 without requiring the replacement of another mold for chamfering, effectively improving ease of use.
