Description

Technical Field

[0001] This invention belongs to the field of metal workpiece processing technology, specifically relating to equipment for drilling and grinding metal workpieces, and particularly to a through-feed processing equipment and its working method. Background Technology

[0002] Drilling is a common machining step in the processing of cylindrical metal workpieces. After drilling, burrs often remain on the edges of the holes, mainly distributed on the top and bottom surfaces of the workpiece.

[0003] In actual production, since the workpieces are fed by a vibratory feeder and transported by pushing the previous workpiece with the next workpiece, burrs will fall off as the workpieces move in the conveyor channel or accumulate inside the channel. Burr residues can not only cause blockages in the conveyor channel, resulting in poor workpiece transport and equipment jamming, but may also scratch the workpiece surface, affecting product quality and yield. At the same time, frequent shutdowns are required to clean the conveyor channel of the equipment, thereby reducing overall production efficiency.

[0004] Therefore, how to reduce the reduction in production efficiency caused by the accumulation of residual burrs when using a vibratory feeder to punch and transport workpieces is a technical problem that urgently needs to be solved.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0007] In a first aspect, embodiments of this disclosure provide a through-feed machining apparatus, comprising: Work platform; A vibratory feeding mechanism is installed on the working platform; A drilling mechanism is installed at the discharge end of the conveying channel of the vibrating feeding mechanism and is used to drill holes in metal workpieces. The feeding hopper is located at the discharge end of the punching mechanism; A grinding mechanism is provided between the feeding bin and the drilling mechanism, and is used to grind the burrs on the top surface and the ground surface of the metal workpiece after drilling. The polishing mechanism includes: A top-fixed grinding block is disposed at the top of the conveying channel and is used to grind burrs on the top of the metal workpiece. A bottom sliding grinding block is disposed at the bottom of the conveying channel and is used to grind burrs on the bottom of the metal workpiece. The waste collection chamber is located below the grinding mechanism and is used to clean the burrs that have been ground off.

[0008] In one optional embodiment, the conveying channel is provided with a receiving groove near the bottom of the unloading hopper; The sidewall of the receiving groove is provided with a guide groove; A slider is provided at the fitting point between the side wall of the bottom sliding grinding block and the guide groove; Furthermore, the slider is elastically connected to the bottom of the guide groove via a reset spring; The top surface of the bottom sliding grinding block protrudes from the receiving groove. When the metal workpiece is conveyed in the conveying channel, the top fixed grinding block grinds the burrs on the top of the metal workpiece, causing the bottom sliding grinding block to slide downward along the guide groove so that the grinding surface of the bottom sliding grinding block is lower than the bottom surface of the metal workpiece, thereby grinding the burrs on the bottom of the metal workpiece.

[0009] In one alternative embodiment, the waste collection chamber is disposed at the bottom of the receiving tank; The waste collection chamber is connected to an external negative pressure source; When the metal workpiece drives the bottom sliding grinding block to slide downward along the guide groove, the waste chip collection chamber is opened so that the waste chips generated during grinding can be initially cleaned by an external negative pressure source.

[0010] In one optional embodiment, a cleaning hole is provided in the middle of the bottom sliding polishing block; The cleaning hole is connected to the waste collection chamber; When the external negative pressure source is working, the waste chips from grinding the metal workpiece are cleaned a second time through the cleaning hole.

[0011] In one optional embodiment, the distance from the axis of the cleaning hole to the end of the bottom sliding grinding block near the drilling mechanism is L1; The diameter of the hole drilled in the metal workpiece is L2; Where L1 > L2, burrs on the bottom of the metal workpiece are removed.

[0012] In one optional embodiment, the bottom of the receiving groove includes a horizontal surface and an inclined surface; The shape of the bottom surface of the bottom sliding grinding block is adapted to the shape of the bottom of the receiving groove; Furthermore, a portion of the bottom surface of the bottom sliding polishing block is in contact with the inclined surface of the receiving groove; The inclination angle of the inclined surface is the same as the inclination angle of the guide groove.

[0013] In one optional embodiment, the width of the bottom sliding polishing block is L; The outer diameter of the metal workpiece is L3, and the diameter of the hole drilled in the metal workpiece is L2; Furthermore, L2 < L < L3.

[0014] In one optional embodiment, the punching mechanism includes: Two clamping blocks are arranged opposite each other, and the two clamping blocks are respectively arranged on both sides of the conveying channel and are used to clamp the metal workpiece. A top punching head is disposed at the top of the conveying channel and is used to punch holes in the clamped metal workpiece. A bottom punching head is located at the bottom of the conveying channel and is used to punch holes in the clamped metal workpiece.

[0015] In an optional embodiment, the punching mechanism further includes: Two drive cylinders are connected to the corresponding clamping blocks.

[0016] Secondly, this disclosure also provides a working method for the through-feed processing equipment as described above, the working method comprising: The vibrating feeding mechanism sequentially transports metal workpieces into the conveying channel; The drilling mechanism drills holes in the metal workpieces in the conveying channel; The grinding mechanism deburrs the top and bottom of the metal workpieces that have been drilled in the conveying channel, and then conveys them to the unloading hopper through the conveying channel.

[0017] The beneficial effects of this invention are that the through-feed processing equipment and its working method remove burrs from the top and bottom surfaces of the metal workpiece after drilling by setting a top fixed grinding block and a bottom sliding grinding block between the drilling mechanism and the unloading bin. This prevents burrs from remaining and accumulating in the conveying channel, thereby avoiding channel blockage, workpiece conveying jams, and workpiece surface scratches, significantly reducing downtime for cleaning, and improving production efficiency and product quality. Simultaneously, the waste chip collection chamber can promptly clean up the waste chips generated during grinding, ensuring long-term stable operation of the equipment.

Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0025] In this document, when a metal workpiece or layer is referred to as being “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another metal workpiece or layer, it may be directly located, joined, connected, attached to, or coupled to the other metal workpiece or layer, or there may be an intermediate metal workpiece or layer present. Conversely, when a metal workpiece is referred to as being “directly on another metal workpiece or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another metal workpiece or layer, there may be no intermediate metal workpiece or layer present. Other terms used to describe the relationship between metal workpieces should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0026] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0027] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting.

[0029] Research has found that when punched metal workpieces are transported in the conveyor channel, burrs will fall off as the workpiece moves in the channel or accumulate inside the channel. Burr residue can not only cause blockage of the conveyor channel, resulting in poor workpiece transport and equipment jamming, but may also scratch the workpiece surface, affecting product quality and yield.

[0030] Based on the above research, this disclosure provides a through-feed processing device and its working method. By setting a top fixed grinding block 510 and a bottom sliding grinding block 520 between the drilling mechanism 300 and the unloading bin 400, burrs on the top and bottom surfaces of the metal workpiece 700 after drilling are removed, preventing burrs from remaining and accumulating in the conveying channel 210. This avoids channel blockage, workpiece conveying jams, and workpiece surface scratches, significantly reducing downtime for cleaning and improving production efficiency and product quality. Simultaneously, the waste chip collection chamber 600 can promptly clean up the waste chips generated during grinding, ensuring long-term stable operation of the equipment.

[0031] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Please see Figure 1 and Figure 2At least one embodiment provides a through-feed processing device, comprising: a work platform 100; a vibratory feeding mechanism 200 disposed on the work platform 100; a drilling mechanism 300 disposed at the discharge end of the conveying channel 210 of the vibratory feeding mechanism 200 and used for drilling holes in a metal workpiece 700; and a discharge bin 400 disposed at the discharge end of the drilling mechanism 300; wherein a grinding mechanism 500 is disposed between the discharge bin 400 and the drilling mechanism 300 and used for grinding the workpiece after drilling. The grinding mechanism 500 is used to grind the burrs on the top surface and the ground surface of the metal workpiece 700. The grinding mechanism 500 includes: a top fixed grinding block 510, which is disposed at the top of the conveying channel 210 and is used to grind the burrs on the top of the metal workpiece 700; a bottom sliding grinding block 520, which is disposed at the bottom of the conveying channel 210 and is used to grind the burrs on the bottom of the metal workpiece 700; and a waste chip collection chamber 600, which is disposed below the grinding mechanism 500 and is used to clean the burrs that have been ground off.

[0035] By installing a top fixed grinding block 510 and a bottom sliding grinding block 520 between the drilling mechanism 300 and the unloading bin 400, burrs on the top and bottom surfaces of the metal workpiece 700 after drilling are removed. This prevents burrs from remaining and accumulating in the conveying channel 210, thus avoiding channel blockage, workpiece conveying jams, and workpiece surface scratches. It significantly reduces downtime for cleaning, improving production efficiency and product quality. Simultaneously, the waste chip collection chamber 600 ensures timely cleaning of grinding waste chips, guaranteeing long-term stable operation of the equipment.

[0036] The conveying direction of the metal workpiece is as follows: Figure 2 As shown in F1.

[0037] Please see Figure 2 and Figure 3 The conveying channel 210 is provided with a receiving groove 211 near the bottom of the unloading bin 400; the side wall of the receiving groove 211 is provided with a guide groove 212; a slider is provided at the fitting point between the side wall of the bottom sliding grinding block 520 and the guide groove 212; and the slider is elastically connected to the bottom of the guide groove 212 by a return spring 213; wherein, the top surface of the bottom sliding grinding block 520 protrudes from the receiving groove 211, and when the metal workpiece 700 is conveyed in the conveying channel 210, the top fixed grinding block 510 grinds the burrs on the top of the metal workpiece 700, causing the bottom sliding grinding block 520 to slide downward along the guide groove 212 (the sliding direction is as follows). Figure 4 As shown in F2), so that the grinding surface of the bottom sliding grinding block 520 is lower than the bottom surface of the metal workpiece 700 (e.g., Figure 5 As shown), to grind the burrs on the bottom of the metal workpiece 700.

[0038] Through the cooperation of the receiving groove 211, the guide groove 212, and the return spring 213, the bottom sliding grinding block 520 is automatically pressed down during the metal workpiece conveying process (the pressing direction is as follows). Figure 4 (As shown in F2) and reset, ensuring that the burrs on the bottom surface of the workpiece are thoroughly ground, avoiding burr detachment and residual channels; at the same time, the elastic design adapts to different workpiece thicknesses, improving the equipment's versatility and grinding stability. Meanwhile, the return spring 213 increases the pressure between the metal workpiece 700 and the top fixed grinding block 510 and the bottom sliding grinding block 520, further improving the burr removal rate.

[0039] It should be noted that a segmented removal method is used when cleaning burrs. First, the burrs on the top of the metal workpiece are removed, and then the burrs on the bottom are removed. The grinding of the top provides a support reference for the sliding of the bottom, ensuring that the workpiece position is stable when the bottom surface is ground.

[0040] Please see Figure 2 and Figure 3 The waste chip collection chamber 600 is located at the bottom of the receiving groove 211; the waste chip collection chamber 600 is connected to an external negative pressure source; the metal workpiece 700 drives the bottom sliding grinding block 520 to tilt downwards along the guide groove 212 (the downward pressing direction is as follows). Figure 4 When sliding (as shown in F2), the waste collection chamber 600 is opened to perform initial cleaning of the waste during grinding through an external negative pressure source.

[0041] The linkage design between the waste collection chamber 600 and the negative pressure source enables real-time initial cleaning of grinding waste, preventing waste from accumulating and clogging the channel from the source, and reducing the frequency of downtime for cleaning.

[0042] Please continue reading. Figure 4 and Figure 5 The bottom sliding grinding block 520 has a cleaning hole 521 in the middle; the cleaning hole 521 is connected to the waste chip collection chamber 600; when the external negative pressure source is working, the waste chips from grinding the metal workpiece 700 are cleaned a second time through the cleaning hole 521.

[0043] The adsorption direction of the negative pressure source is as follows: Figure 4 As shown in F.

[0044] The connection between the cleaning hole 521 and the waste collection chamber 600 creates a secondary suction under negative pressure, precisely removing the micro-burrs remaining on the edge of the workpiece hole, thus solving the scratch problem caused by incomplete burr removal in the prior art.

[0045] Please continue reading. Figure 3 and Figure 4, the axial center of the cleaning hole 521 is at a distance L1 from one end of the bottom sliding grinding block 520 close to the punching mechanism 300; the aperture of the hole punched in the metal workpiece 700 is L2; where L1 > L2 to remove the burrs at the bottom of the metal workpiece 700.

[0046] It is defined that the position of the cleaning hole 521 satisfies L1 > L2, ensuring that the cleaning hole 521 covers the outer edge of the punching area, specifically removing the burrs at the hole opening, improving the hole position quality and preventing the burrs from falling off again.

[0047] Please continue to refer to Figure 2 and Figure 3 , the bottom of the receiving groove 211 includes a horizontal plane 211a and an inclined plane 211b; the shape of the bottom surface of the bottom sliding grinding block 520 is adapted to the shape of the bottom of the receiving groove 211; and, a part of the bottom surface of the bottom sliding grinding block 520 is in contact with the inclined plane 211b of the receiving groove 211; where the inclination angle of the inclined plane 211b is the same as the inclination angle of the guiding inclined groove 212.

[0048] The combined design of the horizontal plane 211a and the inclined plane 211b at the bottom of the receiving groove 211 is completely adapted to the shape of the bottom surface of the sliding block, ensuring that the movement trajectory of the sliding block is stable without deviation and avoiding jamming; at the same time, the inclined plane 211b and the guiding inclined groove 212 have the same angle, optimizing the force transmission efficiency and prolonging the service life of the return spring 213.

[0049] Please refer to Figure 3 and Figure 4 , the width of the bottom sliding grinding block 520 is L; the outer diameter of the metal workpiece 700 is L3, and the aperture of the hole punched in the metal workpiece 700 is L2; and, L2 < L < L3. The width of the sliding block satisfies L2 < L < L3, ensuring that the grinding range covers the hole area but does not interfere with the outer edge of the workpiece, preventing the workpiece from being blocked during transportation while efficiently removing burrs.

[0050] Please refer to Figure 1 and Figure 2 , the punching mechanism 300 includes: two oppositely arranged clamping blocks 310, and the two clamping blocks 310 are respectively arranged on both sides of the conveying channel 210 and are used for clamping the metal workpiece 700; a top punching head 320, which is arranged at the top of the conveying channel 210 and is used for punching the clamped metal workpiece 700; a bottom punching head 330, which is arranged at the bottom of the conveying channel 210 and is used for punching the clamped metal workpiece 700.

[0051] Among them, the punching mechanism 300 further includes: two driving cylinders, which are connected to the corresponding clamping blocks 310.

[0052] Please refer to Figure 6This disclosure also provides a working method for the through-feed processing equipment described above. By setting a top fixed grinding block 510 and a bottom sliding grinding block 520 between the drilling mechanism 300 and the unloading bin 400, burrs on the top and bottom surfaces of the metal workpiece 700 after drilling are removed. This prevents burrs from remaining and accumulating in the conveying channel 210, thereby avoiding channel blockage, workpiece conveying jams, and workpiece surface scratches. This significantly reduces downtime for cleaning and improves production efficiency and product quality. Simultaneously, the waste chip collection chamber 600 can promptly clean up the waste chips generated during grinding, ensuring long-term stable operation of the equipment.

[0053] Specifically, the working method includes: S110: The vibratory feeding mechanism 200 sequentially transports the metal workpieces 700 into the conveying channel 210; S120: The punching mechanism 300 punches holes in the metal workpiece 700 in the conveying channel 210; S130: The grinding mechanism 500 grinds the top and bottom of the metal workpiece 700 that has been drilled in the conveying channel 210, and then conveys it to the unloading bin 400 through the conveying channel 210.

[0054] In summary, the present invention provides a through-feed processing device and its working method. The through-feed processing device includes: a work platform 100; a vibratory feeding mechanism 200 disposed on the work platform 100; a drilling mechanism 300 disposed at the discharge end of the conveying channel 210 of the vibratory feeding mechanism 200 and used for drilling holes in a metal workpiece 700; and a discharge bin 400 disposed at the discharge end of the drilling mechanism 300. A grinding mechanism 50 is provided between the discharge bin 400 and the drilling mechanism 300. The grinding mechanism 500 includes: a top fixed grinding block 510, which is disposed at the top of the conveying channel 210 and used to grind the burrs on the top of the metal workpiece 700; a bottom sliding grinding block 520, which is disposed at the bottom of the conveying channel 210 and used to grind the burrs on the bottom of the metal workpiece 700; and a waste chip collection chamber 600, which is disposed below the grinding mechanism 500 and used to clean the ground burrs. By setting the top fixed grinding block 510 and the bottom sliding grinding block 520 between the drilling mechanism 300 and the unloading bin 400, the burrs on the top and bottom surfaces of the metal workpiece 700 after drilling are removed, preventing burrs from remaining and accumulating in the conveying channel 210, thereby avoiding channel blockage, workpiece conveying jamming, and workpiece surface scratches, significantly reducing downtime for cleaning, and improving production efficiency and product quality. Meanwhile, the waste chip collection chamber 600 can promptly clean up the waste chips generated during grinding, ensuring the long-term stable operation of the equipment. In the description of the embodiments of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. 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 metal workpieces. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0055] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or metal workpiece referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first metal workpiece, component, region, layer, or segment discussed above may be referred to as the second metal workpiece, component, region, layer, or segment.

[0056] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one metal workpiece or feature illustrated in the figures and another metal workpiece or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, a metal workpiece described as “below” or “below” another metal workpiece or feature would be oriented as “above” the other metal workpiece or feature. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0057] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0058] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
