Description

Technical Field

[0001] The invention relates to the technical field related to drilling equipment, in particular to a radial drilling machine for eliminating drilling chips and application thereof in metal parts processing. Background Art

[0002] Radial drilling machine is a machine tool used for processing large and medium-sized workpiece holes. It is widely used in single-piece and small and medium-sized batch production, and is widely used in the field of mechanical processing. It is mainly used for drilling, reaming, reaming, tapping and scraping end faces. With its flexible structural design and diverse functions, radial drilling machine has become one of the indispensable equipment in the field of mechanical processing. With the advancement of CNC technology and precision machining technology, the new radial drilling machine has been significantly improved in terms of machining accuracy and efficiency. In the future, 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, a large amount of metal scraps will be generated along with the continuous rotation of the drill bit. Since the rotation speed of the drill bit is usually fast, some small and light debris can be easily thrown out under the centrifugal force generated by the high-speed rotation. The problems caused by this phenomenon are relatively diverse. On the one hand, the flying debris will be scattered over a large area in the processing area, which seriously affects the cleanliness of the processing environment, adds a lot of inconvenience to the subsequent cleaning work, and greatly increases the time and labor costs of the cleaning work. On the other hand, the flying debris has certain safety hazards, which may cause accidental physical injuries to the staff on site and threaten the personal safety of the staff. In view of this, some drilling machines will be equipped with corresponding protective devices to reduce risks.

[0004] Conventional protective measures usually involve installing an integrated protective cover. When the drill bit is drilling into the workpiece, the protective cover can simultaneously retract according to the preset track, and its retraction method is similar to the expansion and contraction principle of a bellows. However, in actual application, as the drilling depth of the drill bit continues to increase, the retraction amount of the protective cover will also increase accordingly. At this time, since the drill bit still keeps rotating rapidly and generates a large centrifugal force, some fine debris may break through the initial blocking of the protective cover and enter the retraction inflection point of the protective cover, where they will hide. These hidden debris will not only affect the normal retraction function of the protective cover, but may also potentially interfere with the subsequent processing accuracy of the drilling machine. In this regard, the staff is required to regularly suspend the processing of the drilling machine and carefully clean the debris hidden at the retraction inflection 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. Summary of the invention

The elastic support component can cooperate with a follower structure arranged between the assembly arm and the spindle to cause the first enclosure member to move toward or away from the assembly arm.

[0010] As a further solution of the present invention: the elastic support component includes two lugs fixed on the assembly arm, two cross bars slidingly connected to the two lugs respectively, the head ends of the two cross bars are fixedly connected with fastening blocks, and the fastening blocks are fixed to the first enclosure member; wherein, the cross bar is connected to the follower structure through a rolling yielding structure, and a cylindrical spring is also sleeved on the outer periphery of the cross bar, one end of the cylindrical spring is connected to the lug, and the other end is connected and fixed to a frustum at one end of the cross bar away from the fastening block.

[0011] As a further solution of the present invention: the follower structure includes a follower block slidably arranged on the assembly arm, the follower block is fixedly connected to a kit via a cross arm, the kit is rotatably connected to the main shaft, and when the main shaft drives the drill bit to feed, the kit can drive the cross arm to cause the cross bar to slide relative to the lug through the rolling yielding structure.

[0012] As a further solution of the present invention: the rolling yielding structure includes a transmission plate fixedly connected to the cross bar, the transmission plate has a connected inclined surface and a vertical surface formed on one side facing the assembly arm, and a driving wheel is installed at the bottom of the cross arm.

[0013] As a further solution of the present invention: the chip blowing mechanism includes an air blowing pipe movably arranged on the assembly arm, the air blowing pipe passes through the first enclosure and is slidably connected to the first enclosure, the air blowing pipe is connected to an external air pump, and can be driven by a transposition structure arranged on the assembly arm to move radially along the main axis.

[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 effect of the present invention is that the present invention demonstrates a unique innovative concept in the design of the radial drilling machine. When the radial drilling machine is put into operation and the spindle drives the drill bit to perform a feeding operation, the driven mechanism associated therewith will be accurately triggered, thereby prompting the first enclosure member and the second enclosure member to switch from the initial open state to the closed state in an orderly manner. This process is not a simple mechanical movement, but is achieved through a carefully designed mechanical interlocking cooperation. Its advantage is that it can ensure the accuracy and continuity of the protective action, and effectively avoid the problem of protection failure caused by operational errors or mechanical failures; this enclosure closing mechanism driven by mechanical interlocking has a very significant forced protection effect. Compared with the integrated telescopic protective cover, the improved protective measures can more effectively block debris and prevent it from entering and hiding in the retraction inflection point of the protective cover, thereby ensuring that the normal retraction function of the protective cover is not affected, maintaining its stable protective state, always providing reliable protection for the drilling machine processing process, and reducing the potential risks caused by debris interference; since the hiding of debris at the retraction inflection point of the protective cover is avoided, the staff does not need to frequently pause the drilling machine processing work to clean up the debris, which greatly reduces the intensity of daily maintenance work and the required working time, allowing the drilling machine to maintain a continuous processing state for a longer period of time, improving equipment utilization, and thereby improving the overall processing efficiency of the drilling machine; after the first enclosure member and the second enclosure member are closed, a certain closed space can be formed at the drilling hole, which can, on the one hand, prevent the cleanliness of the working environment from being affected by the splashing of debris, and on the other hand, prevent the workers from being affected by the splashing of debris. On the other hand, when the first enclosure member and the second enclosure member are closed, they can effectively isolate the external environment and reduce the entry of heat, thereby effectively improving the cooling effect and cooling efficiency and reducing energy consumption; and because the first enclosure member, the second enclosure member and the chip blowing mechanism adopt mechanical linkage to realize the closing action, the reliability is high, ensuring the rhythm of the drilling action and the chip blowing action to be consistent; in addition, the chip blowing mechanism can automatically change the position of the air blow pipe during the drill bit retraction process during the drilling operation, blow air at the drilled hole, and effectively blow away the waste chips remaining in the drilled hole, and through the shielding of the first enclosure member and the second enclosure member, the waste chips generated during drilling can be fully collected. Therefore, the complexity of the drilling machine operation is simplified, and the reliability of the mechanical structure coordination is high, ensuring the rhythm control of the drill bit retraction and the air blow pipe displacement.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0021] See also Figure 1-Figure 10 In an embodiment of the present invention, a radial drilling machine for eliminating drilling chips includes a drilling machine body, the drilling machine body includes a spindle box 4 and a spindle 6 arranged on the spindle box 4 for assembling a drill bit 7; wherein, a first enclosure 9 and a second enclosure 10 respectively connected to a group of driven mechanisms are provided below the spindle box 4, and the driven mechanism can cause the first enclosure 9 and the second enclosure 10 to switch from an open state to a closed state when the drill bit 7 is fed; a chip blowing mechanism, after the drill bit 7 is retracted, the first enclosure 9 and the second enclosure 10 remain in a closed state, and the chip blowing mechanism can blow compressed air into the drilled hole.

[0022] It should be noted that the drilling machine body also includes a base 1, a column 2 mounted on the base 1, a sleeve 28 provided on the column 2, and a rocker arm 3 connected to the sleeve 28; generally speaking, the movement modes of a radial drilling machine include 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 spindle 6 driving the drill bit 7 to rotate, which is the core movement mode of the radial drilling machine. The rotational movement of the spindle 6 is driven by the spindle motor and realized by a mechanical transmission device, and its direction is usually unidirectional rotation. The rotation speed of the spindle 6 can be adjusted by a speed change mechanism to meet different processing requirements; the feed movement refers to the linear movement of the drill bit 7 in the vertical direction (axial direction) (the staff can control it through the feed handwheel 5 provided on the spindle box 4). This movement is usually controlled by a lifting motor, which is powered by a hydraulic pump to achieve longitudinal feeding of the drill bit 7; the auxiliary movement includes the lifting movement of the rocker arm 3, the rotational movement of the rocker arm 3 and the horizontal movement of the spindle box 4, combined with the auxiliary movement, so as to adjust the working position of the drill bit 7 during work.

[0023] Please refer again Figure 7 and Figure 8 The first enclosure member 9 and the second enclosure member 10 are both arranged in an arc shape. When the two are in a closed state, they fit with the outer wall of the main shaft 6 and form a closed space that can surround the drill bit 7.

[0024] 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, so that the first enclosure 9 and the second enclosure 10 are close to each other, and the first enclosure 9 and the second enclosure 10 are switched from an open state to a closed state, and the upper ends of the first enclosure 9 and the second enclosure 10 are in contact with the main shaft 6; in addition, the bottom of the first enclosure 9 and the second enclosure 10 are both provided with rubber rings 26, and the rubber rings 26 act on the surface of the metal workpiece to shield the debris generated during drilling, thereby preventing the debris from splashing, affecting the cleanliness of the working environment and causing harm to the staff.

[0025] In summary, the present application adopts the enclosure closing mechanism driven by mechanical interlocking. Compared with the existing commonly used integrated telescopic protective cover, the improved protection measures can more effectively block debris and prevent it from entering and hiding in the retraction inflection point of the protective cover, thereby ensuring that the normal retraction 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 potential risks caused by debris interference.

[0026] The interior of the second enclosure member 10 is hollow, and a plurality of notches are provided on the inner wall thereof, and two pipe interfaces are provided on the outer wall thereof, and the two pipe interfaces are respectively connected to an external vacuum cleaner and a cold air generating device.

[0027] Specifically, when the drill bit 7 is drilling, the cold air generating device works. The cold air generating device is a reference to the prior art, which generates cold air through compressed air or other means to achieve rapid cooling of the drilling area. Preferably, in the specific implementation, it can also be used in combination with atomization cooling technology to improve the cooling efficiency. Therefore, it can cool the drill bit 7 and avoid the problem of chips sticking to the surface of the drill bit 7 or the wall of the hole due to the excessive temperature of the drill bit 7. During the drilling process, when it is necessary to clear the debris accumulated in the hole, the staff can operate the feed hand wheel 5 to make the spindle 6 drive the drill bit 7 to gradually retreat until the chip blowing mechanism reaches the working position. The chip blowing mechanism can then blow compressed air into the drilled hole to promote the accumulated chips to be removed. The debris in the hole is discharged. At this time, the first enclosure member 9 and the second enclosure member 10 are still in a closed state. At the same time, the vacuum cleaner is started to absorb and transfer the debris in the closed space formed by the first enclosure member 9 and the second enclosure member 10 to avoid excessive accumulation of debris in and around the hole, which may cause chip jamming. Since the debris is avoided from hiding at the contraction inflection point of the protective cover, the staff does not need to frequently pause the drilling machine processing to clean up the debris, which greatly reduces the intensity of daily maintenance work and the required working time, so that the drilling machine can maintain a continuous processing state for a longer period of time, improve equipment utilization, and thus improve the overall processing efficiency of the drilling machine. In the long run, it is beneficial to reduce production and operation costs and enhance the competitiveness of the enterprise in the market.

[0028] In addition, it should be supplemented that, when the radial drilling machine proposed in the present application 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 prevent the cleanliness of the working environment from being affected by the splashing of debris and cause injuries to the staff. 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, and reducing energy consumption. Since during the drilling process, the first enclosure 9 and the second enclosure 10 remain in a closed state, they can play a safety protection role, avoiding the sudden breakage of the drill bit 7 during the drilling process and causing injuries to personnel, thereby improving the safety of the drilling work.

[0029] It should be noted that, since the driven mechanism connected to the first enclosure member 9 and the second enclosure member 10 is the same, the following is a detailed description of the driven mechanism connected to the first enclosure member 9: Please refer to Figure 6 , Figure 7 as well as 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.

[0030] 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.

[0031] Please refer again Fig. 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 .

[0032] 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.

[0033] 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.

[0034] Please refer again Figure 7 , Figure 8 as well as Fig.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.

[0035] 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.

[0036] 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.
