Description

Technical Field

[0001] This utility model relates to the field of chamfering technology, and in particular to a chamfering machine. Background Technology

[0002] Chamfering, a key process in mechanical manufacturing, is widely used for deburring parts, trimming edges, and preparing assembly guide surfaces. Traditional chamfering typically involves cutting or grinding the workpiece using milling cutters, grinding wheels, or specialized chamfering equipment. During this process, the contact area between the tool and the workpiece generates a large amount of debris due to high-speed friction or cutting action. This debris is made of the same material as the workpiece, including wood, metal, plastic, and ceramics, and its size is typically in the micrometer to millimeter range. Affected by the movement of the processing equipment and airflow, it easily diffuses and suspends in the working environment.

[0003] Currently, the debris generated during chamfering is mainly passively handled through natural settling or simple ventilation equipment. However, due to the light weight and wide diffusion range of the debris, especially in enclosed or semi-enclosed workshop environments, suspended debris is difficult to remove effectively. Even when wearing masks, workers operating the equipment for extended periods may still inhale debris due to its small particle size or insufficient sealing of protective equipment. Medical research indicates that long-term exposure to metallic dust or non-metallic debris significantly increases the risk of occupational diseases such as pneumoconiosis and chronic bronchitis. Furthermore, some alloy material debris (containing cobalt, nickel, etc.) may even trigger cytotoxic reactions. In addition, debris accumulation in the workshop can contaminate precision equipment components, affecting machining accuracy. Therefore, we provide a chamfering machine to address these issues.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figure 1 — Figure 6 The example shown.

[0035] A chamfering machine includes a frame 100, a platform 200, a suction mounting block 300, a power unit 400, and a suction pipe 500.

[0036] In some specific embodiments, the platform 200 has a first clearance hole 201, the suction mounting block 300 is fixedly mounted on the bottom surface of the platform 200, the suction mounting block 300 has a suction cavity 310, the platform 200 is used to cover the suction cavity 310, the suction cavity 310 is connected to the first clearance hole 201, the power device 400 is fixedly mounted on the bottom surface of the platform 200, the power output end of the power device 400 is located in the suction cavity 310, the rotating end of the power device 400 is equipped with a chamfer head 401, and part of the chamfer head 401 passes through the first clearance hole 201 to the top of the platform 200, a preset gap is formed between the first clearance hole 201 and the chamfer head 401, and the suction pipe 500 is fixedly mounted on the suction mounting block 300, and the suction pipe 500 is connected to the suction cavity 310.

[0037] See Figure 1 As shown, the chamfering head 401 protrudes above the carrier plate 210 through the first clearance hole 201, so that the chamfering head 401 can be used to chamfer the workpiece when it rotates. Specifically, when chamfering the workpiece, the chamfering head 401 is first driven to rotate by the power device 400. When the workpiece passes through the chamfering head 401, its edge is chamfered. At this time, the suction pipe 500 sucks the suction chamber 310. Since the air pressure in the suction chamber 310 is lower than the external air pressure, the debris generated by chamfering the workpiece will enter the suction chamber 310 through the gap between the chamfering head 401 and the first clearance hole 201. Finally, the debris is sucked and collected by the suction pipe 500 to prevent the debris from entering the working environment and causing injury to the workers.

[0038] It is understandable that the end of the suction pipe 500 away from the suction mounting block 300 is connected to a negative pressure generating device. For example, the suction pipe 500 can be connected to a vacuum cleaner or other negative pressure generating device to suck up debris that enters the suction chamber 310.

[0039] Furthermore, during the rotation of the chamfering head 401, the centrifugal force generated by the chamfering head 401 will also throw the debris into the suction chamber 310 to a certain extent.

[0040] In some specific embodiments, the stage 200 includes a carrier plate 210 fixedly mounted on the frame 100, a receiving groove 211 is provided at the position of the suction mounting block 300, a cover plate 220 covering the suction cavity 310 is provided at the position of the receiving groove 211, and a first clearance hole 201 is provided on the cover plate 220.

[0041] See Figure 2 and Figure 3As shown, to facilitate the replacement of the chamfer head 401, a receiving groove 211 is provided on the carrier plate 210. At this time, the suction chamber 310 is connected to the outside through the receiving groove 211, and the chamfer head 401 is also exposed to the outside, which facilitates the replacement of the chamfer head 401. Therefore, it is not necessary to remove the carrier plate 210 to replace the chamfer head 401. Furthermore, the receiving groove 211 is covered by the cover plate 220, and the first clearance hole 201 is provided on the cover plate 220. The part of the chamfer head 401 that passes through the first clearance hole 201 on the cover plate 220 is exposed to the outside. It can be understood that when it is necessary to disassemble and replace the chamfer head 401, it is only necessary to remove the cover plate 220 from the receiving groove 211 to carry out the replacement process. It is not necessary to disassemble the carrier plate 210, making the replacement more convenient.

[0042] In this embodiment, the receiving groove 211 is a stepped groove, and the cover plate 220 is placed on the stepped surface of the stepped groove to cover the receiving groove 211.

[0043] In some specific embodiments, the power unit 400 includes a connecting frame 410 fixedly installed on the bottom surface of the platform 200, a rotary drive 420 fixedly installed on the connecting frame 410, a rotating shaft assembly 430 rotatably installed on the suction mounting block 300, a portion of the rotating shaft assembly 430 extending into the suction chamber 310, and a transmission belt 440 provided between the end of the rotating shaft assembly 430 away from the suction mounting block 300 and the rotating output end of the rotary drive 420.

[0044] See Figure 3 As shown, in this embodiment, a connecting frame 410 is formed by multiple connecting columns and a horizontal plate. The horizontal plate is rectangular, and there are four connecting columns distributed at the four corners of the horizontal plate and fixedly connected to the bottom surface of the platform 200. When chamfering the workpiece, the rotary drive 420 is first started to drive the rotating shaft assembly 430 to rotate through the transmission belt 440, thereby driving the chamfering head 401 to rotate and cut and chamfer the workpiece.

[0045] In some specific embodiments, the rotating shaft assembly 430 includes a mounting base 431 fixedly mounted on the suction mounting block 300. The mounting base 431 has a mounting hole 4311, in which a drive shaft 432 is rotatably mounted. The drive shaft 432 extends into the suction chamber 310. A coupling 433 is provided on the top of the drive shaft 432, and the chamfered head 401 is fixedly connected to the drive shaft 432 for transmission through the coupling 433.

[0046] See Figure 4 and Figure 5As shown, the mounting base 431 is fixedly connected to the suction mounting block 300. The top of the drive shaft 432, which is rotatably connected inside the mounting base 431, extends into the suction chamber 310. The top of the suction chamber 310 is fixedly connected to the chamfer head 401 through the coupling 433. A pulley is installed at the end (bottom) of the drive shaft 432 away from the chamfer head 401. A drive belt 440 is wound on the pulley, so that the rotation drive 420 can drive the drive shaft 432 and the chamfer head 401 to rotate through the drive belt 440.

[0047] In this embodiment, the coupling 433 is a rigid coupling, that is, one end is fixedly connected to the drive shaft 432 and the other end is connected to the chamfer head 401. The coupling 433 transmits the power from the drive shaft 432 to drive the chamfer head 401 to rotate.

[0048] In some specific embodiments, at least two bearings 435 are provided at intervals in the mounting hole 4311. The inner ring of the bearing 435 is connected to the drive shaft 432, and the outer ring of the bearing 435 is connected to the inner wall of the mounting hole 4311.

[0049] Please continue reading. Figure 5 As shown, in order to make the drive shaft 432 rotate more stably in the mounting hole 4311, multiple bearings 435 are installed in the mounting hole 4311 to increase the stability of rotation and prevent the drive shaft 432 from bending. Specifically, in this embodiment, two bearings 435 are installed in the mounting hole 4311, and the two bearings 435 are located at the two ends of the drive shaft 432, thereby supporting the drive shaft 432 and preventing the drive shaft 432 from bending during transmission due to its large span.

[0050] For example, bearing 435 can be selected as a deep groove ball bearing, which can withstand both radial and axial forces.

[0051] In some specific embodiments, the rotating shaft assembly 430 further includes a dustproof assembly 434. The dustproof assembly 434 includes a flange 4341 fixedly mounted on the top of the mounting base 431. A protrusion 4342 is provided on the upper surface of the flange 4341. A bushing 4343 is fixedly mounted on the circumferential surface of the coupling 433. An annular groove 4344 is provided on the end face of the bushing 4343 facing the flange 4341. The protrusion 4342 extends into the annular groove 4344.

[0052] See Figure 5 and Figure 6As shown, in order to prevent dust from entering the mounting hole 4311 through the top of the mounting base 431, a mounting flange 4341 is fixedly mounted on the top of the mounting base 431, and then a bushing 4343 is fixedly mounted on the coupling 433. The protrusion 4342 of the flange 4341 extends into the annular groove 4344 of the bushing 4343. The protrusion 4342 and the annular groove 4344 cooperate to form a "U"-shaped channel, thereby increasing the length of the channel. Since the entrance of the channel is at the bottom, it is difficult for the debris generated by the chamfering of the workpiece to enter the mounting hole 4311 through the annular groove 4344, thus achieving the dustproof function.

[0053] Understandably, flange 4341 is fixed to mounting base 431, while bushing 4343 is rotated to be connected to coupling 433. Therefore, protrusion 4342 does not contact the inner wall of annular groove 4344.

[0054] In some specific embodiments, the power unit 400 further includes a height adjustment structure 436. The chamfered head 401 has a mounting shaft 4011, which is mounted in the coupling 433. The height adjustment structure 436 includes a threaded hole 4361 formed in the mounting shaft 4011 toward the drive shaft 432. An adjusting bolt 4362 is installed in the threaded hole 4361. The adjusting bolt 4362 can be screwed to extend away from the chamfered head 401 and abut against the top surface of the drive shaft 432.

[0055] See Figure 5 As shown, in order to adjust the side length of the chamfer, the length of the chamfer head 401 extending outside the first clearance hole 201 can be adjusted. For this purpose, the height of the chamfer head 401 needs to be adjusted. Specifically, when it is necessary to adjust the height of the chamfer head 401, simply remove the chamfer head 401 first, and then screw the adjusting bolt 4362 out of the threaded hole 4361 by a certain length. When the chamfer head 401 is connected to the coupling 433, the end of the adjusting bolt 4362 will abut against the top of the drive shaft 432. That is, only the length of the adjusting bolt 4362 extending out of the threaded hole 4361 needs to be adjusted to adjust the height of the chamfer head 401 extending outside the first clearance hole 201, thereby adjusting the side length of the chamfer. The operation is simple and does not require changing different types of chamfer heads 401 to adjust the side length of the chamfer.

[0056] In some specific embodiments, the chamfering machine also includes a side guard assembly 600, which includes a guide post 610 fixedly installed on the opposite side of the frame 100, a lifting plate 620 slidably disposed on the guide post 610, and a second clearance hole 630 opened on the lifting plate 620 at the chamfering head 401 position; at least one handle 640 is fixedly installed on the lifting plate 620.

[0057] See Figure 1As shown, when it is necessary to chamfer the sheet material, the lifting plate 620 is installed on the guide post 610 and then placed on the platform 200 under the action of gravity. At this time, the chamfering head 401 is located at the position of the second clearance hole 630. When in use, the sheet material only needs to move along the side of the lifting plate 620 and pass through the chamfering head 401 to achieve the cutting chamfer.

[0058] Understandably, when the plate does not need to be chamfered, that is, when the inner edge of the pipe end needs to be chamfered, you only need to grab the handle 640 with both hands to lift the lifting plate 620 and remove it from the guide post 610. At this time, the pipe rotates around the chamfering head 401 so that the inner edge of the pipe contacts the chamfering head 401 to achieve the cutting chamfer.

[0059] The working process of this utility model is as follows: The rotary drive component 420 of the power unit 400 drives the rotating shaft assembly 430 to rotate through the transmission belt 440, and the transmission shaft 432 drives the chamfering head 401 to rotate at high speed through the coupling 433. When the workpiece is placed on the cover plate 220 of the platform 200, the chamfering head 401 passes through the first clearance hole 201 to cut the edge of the workpiece. The generated debris is drawn into the suction chamber 310 by the chamfering head 401 under the action of suction force. At the same time, the suction pipe 500 is connected to an external negative pressure device to continuously suction the suction chamber 310, so that the preset gap between the first clearance hole 201 and the chamfering head 401 forms an airflow channel. The debris is collected by the airflow through the suction chamber 310 into the suction pipe 500. The lifting plate 620 of the edge-guard assembly 600 is adjusted up and down along the guide post 610: when processing sheet metal, the lifting plate 620 limits the movement path of the sheet metal through the second clearance hole 630; when processing pipes, the lifting plate 620 is removed to allow the pipe to rotate around the chamfer head 401. The height adjustment structure 436 changes the amount of the chamfer head 401 extending beyond the first clearance hole 201 by turning the adjusting bolt 4362, thereby precisely controlling the chamfer size.

[0060] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
