Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and in particular to a radial drilling machine for eliminating drilling chip jamming and its application in metal part processing. Background Art

[0002] A radial drilling machine is a machine tool used for machining holes in medium and large-sized workpieces, widely used in single-piece and small and medium batch production, and widely used in the field of machining. It is mainly used for various machining forms such as drilling, reaming, boring, tapping, and facing. With its flexible structural design and diverse functions, the radial drilling machine has become one of the indispensable equipment in the machining field. With the progress of numerical control technology and precision machining technology, the processing accuracy and efficiency of new radial drilling machines have been significantly improved. In the future, the universal radial drilling machine will pay more attention to intelligent and integrated design to meet personalized needs.

[0003] In the processing operation process of the drilling machine, with the continuous rotation of the drill bit, a large number of metal chips will be generated. Given that the rotation speed of the drill bit is usually relatively fast, some small and light chips are easily thrown out under the action of the centrifugal force generated by high-speed rotation. The problems brought about by this phenomenon are relatively diverse. On the one hand, the flying chips will be scattered over a large area in the processing area, seriously affecting the cleanliness of the processing environment, adding a lot of inconvenience to the subsequent cleaning work, and significantly increasing the time cost and labor cost of the cleaning work. On the other hand, the flying chips pose a certain safety hazard and may cause accidental physical injuries to the on-site workers, threatening the personal safety of the workers. In view of this, some drilling machines are equipped with corresponding protective devices to reduce the risk.

[0004] Conventional protective measures usually involve installing an integrally formed protective cover. During the process of the drill bit drilling into the workpiece, the protective cover can simultaneously perform a contraction action according to a preset track, and its contraction method is similar to the telescopic principle of a bellows. However, in the actual application process, as the drilling depth of the drill bit increases, the contraction amount of the protective cover will also increase accordingly. At this time, since the drill bit still rotates rapidly and generates a large centrifugal force, some small chips may break through the initial blockage of the protective cover, enter the contraction fold point of the protective cover, and be hidden here. These hidden chips will not only affect the normal contraction function of the protective cover but also may potentially interfere with the subsequent processing accuracy of the drilling machine. To this end, it is necessary for the staff to regularly suspend the processing work of the drilling machine and carefully clean the chips hidden at the contraction fold point of the protective cover, which undoubtedly increases the intensity and working time of the daily maintenance work of the drilling machine and also reduces the overall processing efficiency of the drilling machine to a certain extent.

[0015] An application of the radial drilling machine capable of eliminating drilling chips in metal parts processing.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention demonstrates a unique innovative concept in the design of the radial drill press. When the radial drill press is in operation and the spindle drives the drill bit for the feeding operation, the associated driven mechanism will be accurately triggered, thereby prompting the first enclosure member and the second enclosure member to orderly switch from the initial open state to the closed state. This process is not a simple mechanical movement but is achieved through a carefully designed mechanical interlock cooperation. Its advantage lies in ensuring the accuracy and coherence of the protective action, effectively avoiding the problem of protective failure caused by operation errors or mechanical failures; this enclosure member closing mechanism driven by mechanical interlock brings a very significant forced protection effect. Compared with the integrated telescopic protective cover, the improved protective measure can more effectively block debris and prevent it from entering and hiding at the shrinkage fold point of the protective cover, thereby ensuring the normal shrinkage function of the protective cover, maintaining its stable protective state, always providing reliable protection for the drill press processing process, and reducing potential risks caused by debris interference; since debris is prevented from hiding at the shrinkage fold point of the protective cover, the staff does not need to frequently pause the drill press processing work to clean up this debris, greatly reducing the intensity and required working time of daily maintenance work, enabling the drill press to maintain a continuous processing state for a longer time, improving the equipment utilization rate, and thus enhancing the overall processing efficiency of the drill press; after the first enclosure member and the second enclosure member are closed, a certain enclosed space can be formed at the drilling position. On the one hand, it can prevent the working environment from being contaminated by debris splashing and prevent damage to the staff. On the other hand, when the first enclosure member and the second enclosure member are closed, they can effectively isolate the external environment, reduce the heat entry, thereby effectively improving the cooling effect and cooling efficiency and reducing the energy consumption; and because the first enclosure member, the second enclosure member, and the chip blowing mechanism are mechanically linked to achieve the closing action, the reliability is high, ensuring that the drilling action and the chip blowing action have the same rhythm; in addition, the chip blowing mechanism can, during the drilling operation and when the drill bit retracts, the air blowing pipe can complete an automatic position change and blow air at the drilled hole position, effectively blowing out the residual waste chips in the drilled hole position, and through the shielding of the first enclosure member and the second enclosure member, comprehensive collection of the waste chips generated during drilling can be realized. Therefore, the complexity of the drill press operation is simplified, and the reliability of the mechanical structure cooperation is high, ensuring the rhythm control of the drill bit retraction and the air blowing pipe displacement.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In addition, an element in the present invention is referred to as "fixed to" or "disposed on" another element, and it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0030] Please refer to Figures 1-10 , in an embodiment of the present invention, a radial drill press for eliminating drill chips includes a drill press body, the drill press body includes a spindle box 4 and a spindle 6 disposed on the spindle box 4 for assembling a drill bit 7; wherein, a first enclosing member 9 and a second enclosing member 10 respectively connected with a set of driven mechanisms are disposed below the spindle box 4, and the driven mechanism can cause the first enclosing member 9 and the second enclosing member 10 to switch from an open state to a closed state when the drill bit 7 feeds; a chip blowing mechanism, after the drill bit 7 performs a retraction operation, the first enclosing member 9 and the second enclosing member 10 remain in a closed state, and the chip blowing mechanism can blow compressed air into the drilled hole position.

[0031] It should be added that the drill press body further includes a base 1, a column 2 installed on the base 1, a sleeve 28 disposed on the column 2, and a rocker arm 3 connecting the sleeve 28; generally speaking, the movement modes of a radial drill press cover three forms: main movement, feed movement and auxiliary movement, through the coordinated work of a variety of mechanical and electrical devices; specifically, the main movement refers to the rotation movement of the spindle 6 driving the drill bit 7, which is the core movement mode of the radial drill press. The rotation movement of the spindle 6 is driven by a spindle motor and realized through a mechanical transmission device, and its direction is usually unidirectional rotation. The rotation speed of the spindle 6 can be adjusted through a speed change mechanism to adapt to different processing requirements; the feed movement refers to the linear movement of the drill bit 7 in the vertical direction (axial direction) (which can be controlled by an operator through a feed handwheel 5 disposed on the spindle box 4). This movement is usually controlled by a lifting motor and powered by a hydraulic pump to realize the longitudinal feed of the drill bit 7; the auxiliary movement includes the lifting movement of the rocker arm 3, the rotary movement of the rocker arm 3, and the horizontal movement of the spindle box 4, combined with the auxiliary movement to adjust the working position of the drill bit 7 during work.

[0032] Please refer to again Figure 7 And Figure 8 , both the first enclosing member 9 and the second enclosing member 10 are arranged in an arc shape, and when the two are in a closed state, they are attached to the outer wall of the spindle 6 and form a closed space that can surround the drill bit 7.

[0033] Furthermore, after adjusting the working position of the drill bit 7, the main shaft 6 will drive the drill bit 7 to rotate and drive the drill bit 7 to move downward. In the previous stroke, the driven mechanism is triggered, causing the first enclosure member 9 and the second enclosure member 10 to approach each other, and the first enclosure member 9 and the second enclosure member 10 are switched from the open state to the closed state, and the upper ends of the first enclosure member 9 and the second enclosure member 10 are attached to the main shaft 6. In addition, rubber rings 26 are provided at the bottoms of the first enclosure member 9 and the second enclosure member 10, and the rubber rings 26 act on the surface of the metal workpiece to play a certain role in blocking the chips generated during drilling, avoiding the chips from splashing and affecting the cleanliness of the working environment and causing harm to the staff.

[0034] In summary, through the enclosure member closing mechanism driven by mechanical interlock, compared with the commonly used integral telescopic protective cover in the prior art, the improved protection measure can more effectively block the chips and prevent them from entering and hiding at the shrinkage fold point of the protective cover, thus ensuring that the normal shrinkage function of the protective cover is not affected and maintaining its stable protection state, always providing reliable protection for the drilling machine processing process and reducing the potential risks caused by chip interference.

[0035] The interior of the second enclosure member 10 is hollow, and a plurality of notches are provided on its inner wall, and two pipeline interfaces are provided on its outer wall, and the two pipeline interfaces are respectively connected to an external vacuum cleaner and a cold air generating device.

[0036] Specifically, during the drilling process of the drill bit 7, the cold air generating device operates. The cold air generating device is a reference to the prior art, which generates cold air through compressed air or other means to rapidly cool the drilling area. Preferably, in specific implementation, it can also be used in combination with the atomization cooling technology to improve the cooling efficiency. Therefore, it can play a role in cooling the drill bit 7 and avoid the problem of chips sticking to the surface of the drill bit 7 or the hole wall due to the overheating of the drill bit 7. During the drilling process, when it is necessary to remove the debris accumulated in the hole, the operator can control the feed handwheel 5 to make the main shaft 6 drive the drill bit 7 to gradually retract until the chip blowing mechanism reaches the working position. The chip blowing mechanism can then blow compressed air into the drilled hole to prompt the accumulated debris to be discharged. At this time, the first baffle 9 and the second baffle 10 are still in the closed state. Meanwhile, the vacuum cleaner is started to suck and transfer the debris in the closed space formed by the first baffle 9 and the second baffle 10, avoiding excessive accumulation of debris inside and around the hole, which may cause chip jamming. Since the hiding of debris at the shrinkage fold point of the protective cover is avoided, the operator does not need to frequently pause the drilling machine processing work to clean up this debris, greatly reducing the intensity and required working time of daily maintenance work, enabling the drilling machine to maintain a continuous processing state for a longer time, improving the equipment utilization rate, and further enhancing the overall processing efficiency of the drilling machine. In the long run, it is beneficial to reduce the production and operation costs and enhance the competitiveness of the enterprise in the market.

[0037] In addition, it should be further noted that for the radial drilling machine proposed in this application, when the main shaft 6 drives the drill bit 7 to feed during operation, it can prompt the driven mechanism to drive the first baffle 9 and the second baffle 10 to switch from the open state to the closed state. Therefore, it can form a certain closed space at the drilling position. On the one hand, it can avoid the influence of debris splashing on the cleanliness of the working environment and damage to the operator. On the other hand, when the first baffle 9 and the second baffle 10 are closed, they can effectively isolate the external environment, reduce the entry of heat, thereby effectively improving the cooling effect and cooling efficiency, and reducing the energy consumption. Since the first baffle 9 and the second baffle 10 remain in the closed state during the drilling process, they can play a safety protection role, avoiding injury to the operator caused by the sudden breakage of the drill bit 7 during the drilling process, and enhancing the safety of the drilling work.

[0038] It should be noted that since the driven mechanisms connected to the first baffle 9 and the second baffle 10 are the same, the following will elaborate in detail on the driven mechanism connected to the first baffle 9: Please refer to again Figure 6 、 Figure 7 and Figure 8The driven mechanism includes an assembly arm 8 fixed to the side of the spindle box 4, and also includes: an elastic support component, which is arranged on the assembly arm 8 and connected to the first enclosure 9. The elastic support component can cooperate with the follower structure arranged between the assembly arm 8 and the spindle 6 to cause the first enclosure 9 to move toward or away from the assembly arm 8.

[0039] Specifically, during the working process, the main shaft 6 can drive the drill bit 7 to rotate and can drive the drill bit 7 to feed. In the first stroke of the drill bit 7 feeding, the main shaft 6 drives the follower structure to move along the length direction of the assembly arm 8, so that the follower structure cooperates with the elastic support component, so that the elastic support component prompts the first enclosure 9 to move away from the assembly arm 8, so that the first enclosure 9 and the second enclosure 10 are switched from an open state to a closed state to avoid some debris splashing during the drilling process, and to avoid the problem of debris splashing and being difficult to collect when blowing away the debris in the drilled hole. At the same time, the first enclosure 9 and the second enclosure 10 in the closed state effectively isolate the external environment and reduce the entry of heat, thereby effectively improving the cooling effect and cooling efficiency.

[0040] Please refer again Figure 9 The elastic support assembly includes two lugs 15 fixedly arranged on the assembly arm 8, and two cross bars 16 slidably connected to the two lugs 15, respectively. The head ends of the two cross bars 16 are fixedly connected with fastening blocks 27, and the fastening blocks 27 are fixed to the first enclosure 9; wherein the cross bars 16 are connected to the follower structure through a rolling yielding structure, and a cylindrical spring 18 is also sleeved on the outer periphery of the cross bar 16, one end of the cylindrical spring 18 is connected to the lug 15, and the other end is connected to a round table 17 fixed to one end of the cross bar 16 away from the fastening block 27. The follower structure includes a follower block 13 slidably arranged on the assembly arm 8, and the follower block 13 is fixedly connected with a set 11 through a cross arm 12, and the set 11 is rotationally connected to the spindle 6. When the spindle 6 drives the drill bit 7 to feed, the set 11 can drive the cross arm 12 to cause the cross bar 16 to slide relative to the lug 15 through the rolling yielding structure. The rolling yielding structure includes a transmission plate 19 fixedly connected to the cross bar 16 , and a side of the transmission plate 19 facing the assembly arm 8 is formed with a connected inclined surface 1901 and a vertical surface 1902 , and a driving wheel 14 is installed at the bottom of the cross arm 12 .

[0041] Specifically, during operation, first, the workpiece is fixed on the workbench 25 provided on the base 1, and then, the rocker arm 3 is rotated, the height of the rocker arm 3 is adjusted, and the horizontal position of the spindle box 4 is adjusted until the drill bit 7 corresponds to the point to be drilled, and the rubber ring 26 at the bottom of the first enclosure 9 and the second enclosure 10 contacts the surface of the workpiece; then, the spindle 6 drives the drill bit 7 to start moving downward, and correspondingly, the spindle 6 drives the follower block 13 to gradually slide downward on the assembly arm 8 through the kit 11 and the cross arm 12. The front of this process During a stroke, the driving wheel 14 acts on the inclined surface 1901, so that the transmission plate 19 gives way, the cross bar 16 slides on the lug 15, the columnar spring 18 is compressed, and the cross bar 16 pushes the first enclosure 9 to move away from the assembly arm 8 until the driving wheel 14 abuts against the vertical surface 1902. The first enclosure 9 and the second enclosure 10 remain in a closed state, which blocks flying chips and isolates the external environment, reduces the entry of heat, improves the cooling effect during drilling, and reduces energy consumption.

[0042] After the drilling is completed, the staff controls the main shaft 6 to drive the drill bit 7 to move upward. In the latter part of the upward movement of the drill bit 7, after the driving wheel 14 is separated from the vertical surface 1902, the cylindrical spring 18 will gradually rebound, and the cross bar 16 slides and resets on the lug 15, and drives the first enclosure 9 to move away from the drill bit 7. The first enclosure 9 and the second enclosure 10 are restored from the closed state to the open state, so that the staff can check, maintain or replace the drill bit 7 conveniently after the work is completed.

[0043] Please refer again Figure 7 , Figure 8 as well as Figure 10 The chip blowing mechanism includes an air blowing pipe 20 movably arranged on the assembly arm 8, the air blowing pipe 20 passes through the first enclosure 9 and is slidably connected to the first enclosure 9, the air blowing pipe 20 is connected to an external air pump, and can be driven by a transposition structure arranged on the assembly arm 8 to move along the radial direction of the main shaft 6. The transposition structure includes two guide arms 21 slidably arranged on the assembly arm 8 and fixed to the air blowing pipe 20, and a transposition plate 22 fixedly connected to the two guide arms 21, and the follower block 13 is fixedly connected to a boss 24 through a vertical arm 23; wherein, it should be pointed out that a through slot adapted to the boss 24 is provided on the transposition plate 22, the boss 24 passes through the through slot and is slidably connected to the transposition plate 22, and the through slot includes a first vertical slot 2201, an inclined slot 2202 and a second vertical slot 2203 connected to each other.

[0044] During operation, after the position of the drill bit 7 is adjusted and before the drill bit 7 is fed, the end of the air blow pipe 20 is concentric with the main shaft 6, and in the first section of the downward movement of the drill bit 7, the driving wheel 14 rolls on the inclined surface 1901, so that the first enclosure 9 and the second enclosure 10 are gradually closed. During this process, the boss 24 moves along the first vertical groove 2201; after the first enclosure 9 and the second enclosure 10 are closed, the boss 24 will enter the inclined groove 2202 and slide with the transposition plate 22 through the inclined groove 2202. At this time, the transposition plate 22 pulls the air blow pipe 20 to move close to the assembly arm 8 through the guide arm 21. Until the boss 24 enters the second vertical groove 2203, the air blow pipe 20 is staggered with the main shaft 6, and the drill bit 7 can The drilling can be carried out smoothly; during the drilling process, when it is necessary to clean the debris in the hole, the staff can control the drill bit 7 to retract, and it is necessary to pay attention to the retraction height of the drill bit 7, that is, the boss 24 rises to the connection between the first vertical groove 2201 and the inclined groove 2202. Specifically, during the retraction of the drill bit 7, the boss 24 passes through the second vertical groove 2203 and the inclined groove 2202 in sequence. When passing through the inclined groove 2202, the transposition plate 22 is prompted to push the air pipe 20 away from the assembly arm 8 through the guide arm 21 until the end of the air pipe 20 reaches above the drilled hole. Then, the external air pump works, and air can be blown into the hole through the air pipe 20 to discharge the debris in the hole. At this time, the first enclosure 9 and the second enclosure 10 in the closed state have a shielding effect on the debris to prevent the debris from flying outward.

[0045] As another embodiment of the present invention, an application of the radial drilling machine for eliminating drilling chips in metal parts processing is also proposed. When the radial drilling machine is working, when the spindle 6 drives the drill bit 7 to feed, it can prompt the driven mechanism to drive the first enclosure 9 and the second enclosure 10 to switch from an open state to a closed state, so that a certain closed space can be formed at the drilling location. On the one hand, it can avoid the cleanliness of the working environment and damage to the staff due to the splashing of debris. On the other hand, when the first enclosure 9 and the second enclosure 10 are closed, they can effectively isolate the external environment and reduce the entry of heat, thereby effectively improving the cooling effect and cooling efficiency, reducing energy consumption, and being suitable for popularization and use.
