Description

Technical Field

[0001] This application relates to the field of machining equipment, and in particular to an automatic chamfering machine. Background Technology

[0002] Automatic chamfering machines are widely used in the machining industry, primarily for chamfering and deburring the edges of workpieces. With the rapid development of modern manufacturing, enterprises are increasingly demanding higher production efficiency and product quality, which has driven the research and application of automated equipment.

[0003] Especially for mass production scenarios, highly efficient automated chamfering equipment can significantly reduce labor costs while improving product consistency and precision, becoming an important tool for many manufacturing companies to optimize production processes. However, the automated chamfering equipment commonly used on the market today works by using a feeding device, conveying device, clamping device, transfer device, and chamfering device on the machine. The material is fed by the feeding device and conveyed to the vicinity of the clamping device, then the conveying robot precisely transfers the material to the clamping device. After that, the transfer device sends the clamped material to the double-head chamfering device, where it is chamfered by the working rotating head, and finally unloaded.

[0004] However, in practical applications, this chamfering equipment requires a conveying robot to transfer the material to a pre-set position to a transfer device, and then the transfer device to transfer the material to a clamping device, which increases the complexity of the process and reduces the processing efficiency per unit time. Moreover, for materials of different sizes, during the transfer process, the working end of the chamfering device may not be precisely aligned with the position of the material to be chamfered on the transfer device, thus affecting the accuracy of the chamfering. Summary of the Invention

[0005] In order to reduce the complexity of the chamfering process, improve the chamfering efficiency, and enhance the accuracy of material chamfering, this application provides an automatic chamfering machine.

[0006] To achieve the above objectives, this application provides an automatic chamfering machine, including a machine base. The machine base is sequentially equipped with a feeding device, a pushing device, a positioning device, a clamping device, and a chamfering device according to the chamfering process. The positioning device includes a first positioning plate fixed to the machine base, the first positioning plate having a positioning hole. The pushing device pushes material to the positioning hole of the first positioning plate to abut against it. The clamping device clamps the material abutting against the first positioning plate. The working head of the chamfering device passes through the positioning hole to chamfer the material abutting against the first positioning plate.

[0007] By adopting the above technical solution, the material is first precisely pushed to the positioning hole of the first positioning plate using a pushing device to achieve chamfering positioning. This avoids the positional deviation problem caused by multiple transfers due to inaccurate positioning in existing methods. Next, the clamping device further securely clamps the material that has reached the positioning hole, further ensuring the accuracy of subsequent chamfering operations. Based on this, the working head of the chamfering device, using the positioning hole as a guide path, directly acts on the material to be processed. This not only improves the spatial accuracy of the chamfering operation but also effectively reduces unnecessary adjustments, ultimately achieving efficient and highly accurate chamfering.

[0008] Preferably, the feeding device includes a vibratory feeder for storing materials and a feeding assembly for conveying materials. The feeding end of the feeding assembly is connected to the discharging end of the vibratory feeder, and the discharging end of the feeding assembly is connected to the feeding end of the positioning device. The pushing device pushes the material located at the feeding end of the positioning device to abut against the positioning hole of the first positioning plate.

[0009] By adopting the above technical solution, the vibratory feeder can orderly organize the material and stably output it from the discharge end to the feed end of the feeding component. Since the discharge end of the feeding component is directly connected to the feed end of the positioning device, and the pushing device further pushes the material to abut against the positioning hole of the first positioning plate, the material can be smoothly pushed without additional transfer. This method not only simplifies the material transport path but also effectively reduces potential positional deviations caused by intermediate steps, thereby improving the accuracy and efficiency of material flow throughout the chamfering process. Furthermore, this design makes the equipment structure more compact, helping to reduce the space occupied by the equipment and further improve the space utilization rate of the production site.

[0010] Preferably, the positioning device further includes a second positioning plate and a third positioning plate, which are respectively arranged to form a positioning channel. The pushing device pushes the material through the positioning channel to abut against the positioning hole of the first positioning plate.

[0011] By adopting the above technical solution, firstly, the positioning channel formed by the second and third positioning plates can guide the material during the feeding process, ensuring that the material moves accurately along the predetermined path. Secondly, after the pushing device pushes the material through the positioning channel, it can accurately abut against the positioning holes on the first positioning plate. This design not only simplifies the operation steps that require additional transfer devices in traditional processes, but also effectively improves the positioning accuracy of the material before chamfering, avoiding inaccurate chamfering due to positional deviations. This structural design achieves the goal of improving processing efficiency while ensuring accurate chamfering.

[0012] Preferably, the second positioning plate has a first gap communicating with the positioning channel, and the third positioning plate has a second gap communicating with the positioning channel. The clamping device includes a first driving member and a clamping member. The first driving member is disposed on the machine base and drives the clamping member to pass through the second gap into the positioning channel of the positioning device to clamp the material. The pushing device includes a discharging assembly, which includes a second driving member and a placement plate. The second driving member is disposed on the machine base and drives the placement plate to pass through the first gap into the positioning channel of the positioning device to receive the material. The pushing device pushes the material onto the placement plate.

[0013] By adopting the above technical solution, the clamping device can achieve stable clamping of materials. Specifically, when the pushing device pushes the material to the positioning channel and abuts against the positioning hole of the first positioning plate, the clamping component in the clamping device can smoothly pass through the second gap under the action of the first driving component, and then abut against the material on the placement table, due to the first gap provided on the second positioning plate. This structure not only avoids the inconvenience of operation caused by space limitations in traditional clamping methods, but also ensures the precise execution of the clamping action. In addition, using the first driving component to drive the clamping component to complete the clamping operation effectively improves the stability of material fixation throughout the chamfering process, thereby ensuring the quality and accuracy of subsequent chamfering operations. The third positioning plate is provided with a second gap and is connected to the positioning channel, so that the material feeding component of the pushing device can accurately insert the placement plate into the positioning channel under the action of the second driving component. When the material is pushed to the placement plate by the pushing device, the presence of the first gap ensures that the placement plate can smoothly extend and stably receive the material, thereby effectively improving the accuracy of subsequent chamfering operations.

[0014] Preferably, the pushing device further includes a pushing assembly, which includes a third driving member and a pushing member. The third driving member is disposed on the machine base and drives the pushing member to pass through the positioning channel.

[0015] By adopting the above technical solution, the pusher, driven by the third drive component, can accurately pass through the positioning channel, ensuring the material remains stable during the pushing process. Since the positioning channel is formed by the second and third positioning plates, material deviation or tilting is effectively prevented as the pusher passes through it. This structural arrangement not only improves the accuracy of material pushing but also further ensures that the working head can accurately align with the material to be processed during subsequent chamfering operations, thereby significantly improving chamfering quality and work efficiency.

[0016] Preferably, the automatic chamfering machine further includes an auxiliary feeding device, which includes a fourth driving member and a feeding plate. When feeding, the first driving member drives the placement plate to reset, and at the same time, the fourth driving member drives the feeding plate to move to contact the material on the placement plate.

[0017] By adopting the above technical solution, when the chamfering process is completed and material needs to be unloaded, the first driving component drives the placement plate to reset. During this process, an auxiliary unloading device is set up to ensure that the material can be smoothly removed from the placement plate. Specifically, the fifth driving component in the auxiliary unloading device is activated, moving the unloading plate to the position where it contacts the material on the placement plate. This design avoids the problem of material falling and getting stuck. Through the coordinated operation of various components, the stability and efficiency of the unloading process are effectively improved, thereby enhancing the overall smoothness of the equipment's operation.

[0018] Preferably, the chamfering device further includes a fifth driving member, which is disposed on the machine base and drives the working head to rotate.

[0019] By adopting the above technical solution, firstly, the fifth driving component is securely mounted on the machine base, a design that ensures the stable operation of the entire chamfering device. When the material, after precise positioning, comes into contact with the positioning hole of the first positioning plate, the fifth driving component activates and drives the working head to rotate at high speed. Because the working head can accurately align with the material located within the positioning hole of the first positioning plate, efficient and accurate chamfering operations can be achieved.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The material is directly pushed to the positioning hole of the first positioning plate of the positioning device by the pushing device, which avoids the use of the traditional conveying robot, simplifies the process flow, and improves the processing efficiency per unit time.

[0022] 2. The material is precisely positioned using the positioning holes of the first positioning plate, ensuring that the working head of the chamfering device can accurately act on the position of the material that needs to be chamfered, thus improving the accuracy of the chamfering process; Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses an automatic chamfering machine, referring to... Figure 1 The machine includes a base 1, and is equipped with a feeding device 2, a pushing device 3, a positioning device 4, a clamping device 5, a chamfering device 6, and an auxiliary unloading device 7 arranged in sequence according to the chamfering process. The pushing device 3, the clamping device 5, and the chamfering device 6 are arranged around the positioning device 4. The auxiliary unloading device 7 is located on the pushing device 3 and works with the pushing device 3 to complete the work of each part of the material. This compact structural design facilitates the work of each part on the material on the positioning device 4. In actual production, in order to ensure the safety of the equipment, the chamfering machine is usually placed in a working chamber.

[0028] Specifically, the feeding device 2 includes a vibratory feeder 21 for storing materials and a feeding assembly 22 for conveying materials. The vibratory feeder 21 is placed on one side of the machine base 1. The feeding end of the feeding assembly 22 is connected to the discharging end of the vibratory feeder 21, and the discharging end is connected to the feeding end of the positioning device 4. The vibratory feeder 21 arranges the materials in an orderly manner before conveying them to the feeding end of the positioning device 4, and then pushes them to the next step via the pushing device 3, further improving the feeding efficiency and accuracy. The vibratory feeder 21 is generally made of stainless steel sheet by stamping. The smooth inner wall facilitates the guidance of material flow. At the same time, a vibrator is configured at the bottom to generate directional oscillation force to help the scattered parts separate and rise to the designated track entrance to queue up and wait for instructions to be discharged one by one for use in subsequent processes.

[0029] Specifically, the feeding device 3 includes a feeding assembly 31 for pushing materials and a discharging assembly 32 for providing a placement platform for the materials. The discharging assembly 32 includes a placement plate 321 and a second driving member 322 for driving the placement plate 321 to move. The second driving member 322 can be controlled by a solenoid valve to reciprocate the piston rod. The surface of the placement plate 321 can be sprayed with anti-slip particles to increase the coefficient of friction and prevent the materials from slipping and deviating.

[0030] The feeding assembly 31 includes a feeding component 311 and a third driving component 312 that drives the feeding component 311 to push materials. The feeding assembly 22 conveys the materials to the vicinity of the feeding component 311. The third driving component 312 drives the feeding component 311 to move. The third driving component 312 can be a servo motor as the power source, which has the characteristics of fast response speed and high control accuracy. It can effectively drive the connected lead screw structure to rotate, thereby pushing the nut to move linearly along the lead screw. Of course, a cylinder can also be selected to play the role of the third driving component 312. This embodiment preferably uses a cylinder. Compared with a servo motor, the cylinder has a simple structure and is easy to maintain, making it particularly suitable for some applications with relatively low speed or accuracy requirements.

[0031] In this embodiment, the pusher component 311 is a cuboid component made of high-strength aluminum alloy. The surface is anodized to enhance wear resistance and corrosion resistance. Its front end is designed to better fit the outline of the material to be processed, and the rear end has a threaded hole for connection with the third drive component. To ensure the stability of the pusher component, locking screws or other anti-loosening measures can be added between the pusher component 311 and the third drive component 312.

[0032] Specifically, the positioning device 4 is divided into three parts, such as Figure 2 As shown, the first positioning plate 41, the second positioning plate 42, and the third positioning plate 43 are respectively installed on the machine base 1. The first positioning plate 41 is provided with positioning holes 411 for precise positioning. The second positioning plate 42 and the third positioning plate 43 form a positioning channel 44 for guiding materials smoothly into the placement plate. The discharge end of the feeding component 22 is connected to the feeding end of the positioning device 4. In this embodiment, the third positioning plate 43 of the positioning device 4 abuts against the discharge end of the feeding component 22, and the third positioning plate 43 is provided with a positioning groove 45. The feeding device 4 feeds the material into the positioning slot 45 of the third positioning plate 43 via the feeding component 22. Then, the pusher 311 pushes the material on the positioning slot 45 through the positioning channel 44 to the placement plate 321 so that the material abuts against the positioning hole 411 of the first positioning plate 41, thereby achieving precise guidance and positioning of the material along the pushing direction. It is recommended that all three positioning plates be made of cast iron material because this type of material has good rigidity and shock absorption performance and can withstand long-term high-frequency impact loads without deformation or instability.

[0033] Specifically, the clamping device 5 includes a clamping member 51 and a first driving member 52 for driving the clamping member 51. The first driving member 52 drives the clamping member 51 to clamp the material on the placement plate 321. In this embodiment, due to the compact design of the various devices of the equipment, the clamping device 5 is arranged opposite to the feeding assembly 32, the pushing device 3 is arranged opposite to the chamfering device 6, the second positioning plate 42 is provided with a first gap 421, and the third positioning plate 43 is provided with a second gap 431. The second driving member 322 drives the placement plate 321 to pass through the first gap 421 to the positioning channel 44 of the positioning device 4 to receive the material. The first driving member 52 drives the clamping member 51 to pass through the second gap 431 to the positioning channel 44 of the positioning device 4 to clamp the material. The working end of the clamping member 51 that abuts against the material is designed to conform to the shape of the outer contour of the material, which facilitates the improvement of the clamping stability of the clamping member on the material and further ensures the accuracy of the next chamfering work.

[0034] Specifically, the chamfering device 6 includes a working rotating head 61 for chamfering materials and a fifth driving member 62 for driving the working rotating head 61 to rotate. The fifth driving member 62 drives the working rotating head 61 to rotate and move closer to the first positioning plate 41. The working rotating head 61 can pass through the positioning hole 411 on the first positioning plate 41, and the working end of the working rotating head 62 contacts the material on the placement plate 321 to perform chamfering. The material is pushed to the placement plate 321 through the positioning channel 44 and abuts against the positioning hole 411, realizing the positioning of the material in the pushing direction. At the same time, the clamping member 51 clamps the material, realizing the positioning of the material in another direction. However, simply positioning the material is not enough. Therefore, the positioning hole 411 on the first positioning plate 41 can guide the working rotating head of the chamfering device to accurately pass through the positioning hole 411 to perform chamfering on the material, which is beneficial to improving the accuracy of the chamfering work. In this embodiment, the fifth drive unit 62 can be a variable frequency speed-regulating three-phase asynchronous motor, which is very suitable for driving high-speed rotating operations such as grinding and cutting due to its unique smooth operation characteristics and wide adjustment range. It has a wide range of applications and strong applicability.

[0035] Furthermore, the auxiliary feeding device 7 includes a feeding plate 71 that abuts against the material and a fourth driving member 72 that drives the feeding plate 71 to move. The fourth driving member 72 is disposed on the second driving member 322. After the chamfering work is completed, the second driving member 322 drives the placement plate 321 to be pulled out from the first gap 421, so that the placement plate 321 retracts between the second positioning plate 42 and the second driving member 322, thereby completing the reset of the placement plate 321. At the same time, the fourth driving member 72 drives the feeding plate 71 to quickly reach the material below and abut against the material, so that the material can fall into the positioning channel 44 and be collected.

[0036] The implementation principle of this embodiment is as follows: The equipment, based on a machine base, integrates a series of processes including vibratory feeder 21 feeding, pushing, precise positioning, clamping, chamfering, and auxiliary unloading. The material is first arranged in an orderly manner by the vibratory feeder 21 and conveyed to the feeding assembly 22. Then, the pushing assembly 31 in the pushing device 3 precisely pushes the material into the positioning device composed of the first, second, and third positioning plates. The first positioning plate 41 has positioning holes 411 to ensure precise material positioning, while the second and third positioning plates form a positioning channel 44 to guide the material to the placement plate 321. The clamping device 5 uses the first driving member 52 to drive the clamping member 51 to pass through the gap in the third positioning plate 43 and clamp the material. The chamfering device 6 is driven by the fifth driving member 62 to rotate the working head 61, which passes through the positioning holes 411 of the first positioning plate 41 to precisely chamfer the material. Throughout the process, the material is precisely positioned in both the pushing and clamping directions, ensuring accurate chamfering. Finally, after the chamfering is completed, the auxiliary feeding device 7, through the fourth driving component 72, drives the feeding plate 71 to quickly meet the material, collect and discharge the material, while the second driving component 322 resets the placement plate 321, preparing for the next round of operation. This equipment is compactly designed, with seamless connection between each process, a high degree of automation, and significantly improves the efficiency and accuracy of the chamfering operation.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
