Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a safety protection structure for mechanical processing. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. For example, in the drilling process of raw materials, drilling is generally performed by a drill. During the processing, in order to prevent the drill from overheating and damage, coolant is usually used to cool the drill. In the process of drilling, a large amount of metal debris will be generated. As the drill rotates at high speed, the debris and coolant will splash outward.

[0003] The invention patent with application number CN202010765429.5 discloses a drilling machine, whose structure includes a frame, a vertical sliding device, a drilling machine, a working plate, a support, and a slide rail table. The drilling machine also includes a drive shaft, a drill bit, a telescopic folding protective tube, and a drill bit balancing mechanism. The drilling machine uses the drill bit to drive the drill bit clamping plate, so that when the arc-shaped plate rotates, it drives the drilling grinding layer to grind the edge of the hole to prevent the edge of the hole from causing damage to the contactor. The drill bit clamping plate is designed to assist in balancing the stability of the drill bit rotation and the grinding of the edge of the hole. The negative pressure fan is rotated to generate negative pressure attraction to concentrate the debris into the telescopic folding protective tube to prevent the debris from flying around. It can also cool the drill bit and reduce the heat loss of the drill bit.

[0004] During use, the drilling machine can only perform drilling work of a single depth, resulting in low adaptability. When adjusting the drilling depth, the machine needs to be stopped for adjustment, which brings inconvenience to use. Water cooling cannot be used during cooling. Only air cooling is used for cooling, resulting in poor cooling effect. In the cooling process, the airflow flows from the outside to the inside and then drives the debris to move upward. However, the airflow flowing to the middle position will lose a lot of kinetic energy due to the mutual impact, resulting in the concentration of debris near the drill bit, affecting the efficiency of debris cleaning. The debris cleaning effect is poor. The concentration of debris near the drill bit will also affect the normal operation of the drill bit, and the contact between the debris and the drill bit will accelerate the wear of the drill bit. The general water-cooled drill bit cannot quickly recover the debris and coolant when working, resulting in the coolant and debris remaining on the surface of the raw material, which brings inconvenience to subsequent processing. The coolant cannot be recycled, which increases the cost of processing and operation. Summary of the invention

[0017] 2. The safety protection structure for mechanical processing has a spiral cooling nozzle design. During the rotation process, the coolant inside the cooling nozzle will automatically discharge downward, thereby increasing the flow rate of the coolant through centrifugal force. At the same time, the arc-shaped diffusion scraper will also push the coolant on the outside of the drill bit to flow quickly to the outside when it rotates. The flow rate of the coolant is accelerated by automatic pressurization, thereby improving the cooling efficiency and cooling effect of the coolant on the drill bit.

[0018] 3. The safety protection structure for mechanical processing, the coolant and debris enter the filter box along the spiral lifting plate and then fall to the top of the filter screen, and then with the rotation, the coolant on the surface of the debris passes through the filter screen and gathers in the cavity inside the filter box and outside the filter screen, and then when it stops working, the debris stays inside the filter screen and gathers downward, and the filtered coolant will flow downward through the gap between the adjacent lower supporting partitions and then flow into the top of the partition plate through the flow opening. After secondary filtration through the filter plate above the partition plate, the coolant enters the sealed cavity inside the temporary storage box. During use, the coolant will be automatically filtered and separated, and the separation effect of the coolant on the surface of the debris will be improved through the centrifugal force of rotation, thereby improving the filtering effect of the coolant and preventing waste.

[0019] 4. The safety protection structure for mechanical processing, the filtered coolant in the temporary storage box is pressurized by the pressurized spiral blade, and the coolant is pushed upward by the pressurized spiral blade to enter the inside of the annular drainage cover. The coolant pressed into the inside of the annular drainage cover is finally discharged through the drainage pipe, and there is no need for multiple pumping equipment to discharge. During processing, the ends of the drainage pipe and the coolant supply pipe are extended to the coolant tank through a hose, which can complete the circulation of the coolant by itself, reducing the overall use cost of the equipment, and the supply and recovery of the coolant will automatically stop when the rotation stops, without adding additional control equipment, which is easy to use.

The coolant supply pipe 44 is connected to the inside of the water supply tank 41.

[0024] Specifically, as attached Figure 2 As shown, when the water supply tank 41 rotates, the coolant supply pipe 44 remains relatively still and does not rotate with it. When the mounting seat body 2 rotates, the cooling device 4 is driven to work, and the cooling device 4 is used to spray the coolant with a sub-boost to cool the drilling position of the drill bit 3.

[0025] In this embodiment, the protective device 5 includes a temporary storage box 51, a partition plate 52, an annular drainage cover 53, a drainage pipe 54, a pressurized spiral blade 55, a support arm 56, a middle frame 57, a first plug plate 58, a tail ferrule 59, a spiral lifting plate 60, an arc-shaped diffusion scraper 61, a filter box 62, a first blocking plate 63, a second blocking plate 64 and a lower support partition 65. The temporary storage box 51 is installed on the outer surface of the mounting seat body 2, the partition plate 52 is installed on the upper side of the temporary storage box 51, and the annular drainage cover 53 is installed on the inner side of the temporary storage box 51. The top of the annular drainage cover 53 at the top of the temporary storage box 51 is installed with an annular sealing cover through a bearing, the drainage pipe 54 is installed on the top of the annular sealing cover, the coolant supply pipe 44 and the drainage pipe 54 are tied and fixed at a position close to each other by a strap, the bottom of the pressurizing spiral blade 55 is installed with the bottom inner wall of the temporary storage box 51, the top of the pressurizing spiral blade 55 is installed with the bottom of the partition plate 52, the outer side of the temporary storage box 51 is provided with an inwardly recessed notch, the inner end of the support arm 56 is installed inside the notch through a hinge seat, and the support arm 56 is fixed to the bottom of the partition plate 52. The outer end of the support arm 56 is hinged to the inner wall of the middle frame 57 through a hinge, the first plug plate 58 is installed on the clockwise side of the middle frame 57, the tail ferrule 59 is installed on the counterclockwise side of the middle frame 57, the spiral lifting plate 60 for collecting coolant and debris upward is installed with the inner side wall of the middle frame 57 and the tail ferrule 59, the arc-shaped diffusion scraper 61 for scraping coolant and debris outward is installed with the bottom end of the spiral lifting plate 60, and the inner side of the tail ferrule 59 is installed at the upper end of the spiral lifting plate 60 There is a filter box 62 for filtering debris in the coolant, the inner wall of the tail ferrule 59 is located above the spiral lifting plate 60 and is equipped with a first blocking plate 63 for preventing the coolant above the spiral lifting plate 60 from splashing upward, the interior of the tail ferrule 59 and located on the inner side of the filter box 62 is equipped with a second blocking plate 64 for preventing the coolant from splashing upward, the bottom inner wall of the filter box 62 is equipped with a lower supporting partition 65, and a flow opening is opened at a position close to the inner wall of the filter box 62 and located on the inner side of the lower supporting partition 65.

[0026] Specifically, as attached Figure 2 -Attached Figure 6As shown, the protective device 5 is used to clean up the metal debris generated during the drilling process and the high-temperature coolant after cooling. The arc diffusion scraper 61 is an arc rod. The arc diffusion scraper 61 is located on the outside of the drill bit 3. When the middle frame 57 drives the arc diffusion scraper 61 to expand outward through the spiral lifting plate 60, the end of the arc diffusion scraper 61 away from the spiral lifting plate 60 approaches the outside of the drill bit 3, so that the arc diffusion scraper 61 can automatically approach the drill bit 3 during the drilling process to clean the coolant and debris on the outside of the drill bit 3. The middle frame 57 and the tail ferrule 59 are made of hard and transparent material, and the first plug-in plate 58 is made of elastic plastic. When the middle frame 57 and the tail ferrule 59 expand outward, the first plug-in plate 58 can move outward along the inside of the tail ferrule 59 and deform to expand with the movement, thereby preventing the expansion of the middle frame 57 and the tail ferrule 59 from being hindered.

[0027] In this embodiment, a filter screen 7 is installed on the top of the lower supporting partition 65. The cross-section of the filter screen 7 is L-shaped. The filter screen 7 is stuck in the position inside the lower supporting partition 65 and the second blocking plate 64. The flow opening opened on the inner wall of the filter box 62 is located above the partition plate 52. A one-way valve is installed on the top of the partition plate 52, and a layer of filter plate is installed on the top of the partition plate 52 and above the one-way valve.

[0028] Specifically, as attached Figure 3 and attached Figure 8 As shown, the metal debris falling into the filter box 62 is initially filtered through the filter screen 7, and as the filter box 62 rotates, the metal debris will adhere to the outer surface of the filter screen 7, and then the metal debris is separated from the coolant by centrifugal force.

[0029] In this embodiment, support balls for reducing friction are embedded at the bottom of the middle frame 57, and gaskets for blocking water are installed at the bottom of the first plug plate 58 and the rear clamping sleeve 59, and the plane where the bottom of the gasket is located is higher than the plane where the bottom of the support balls is located.

[0030] Specifically, as attached Figure 6 As shown, the gasket is woven from wear-resistant hemp rope fibers. The gasket weave has fiber gaps. The gasket can be compressed by pressing. After the gasket is compressed, the supporting balls contact the plane of the drilled material for rolling support, thereby reducing friction.

[0031] In this embodiment, the pressurizing spiral blade 55 is spiral-shaped, the bottom of the annular drainage cover 53 is connected to the cavity above the pressurizing spiral blade 55 , and there are three pressurizing spiral blades 55 evenly installed on the bottom inner wall of the temporary storage box 51 .

[0032] Specifically, as attached Figure 4As shown, the annular drainage cover 53 is connected to the internal cavity of the temporary storage box 51. When the pressurizing spiral blade 55 rotates, it pushes the coolant in the internal cavity of the temporary storage box 51 to move upward into the interior of the annular drainage cover 53 to achieve a pressurization effect, and then the coolant is discharged through the drainage pipe 54.

[0033] In this embodiment, the spiral lifting plate 60 is spiral-shaped, and the height of the inner end of the spiral lifting plate 60 is higher than the height of the outer end.

[0034] Specifically, as attached Figure 5 As shown, the metal chips and coolant at the bottom are lifted upward by the spiral lifting plate 60, and during the lifting process, the coolant and metal chips are located on the outer side of the spiral lifting plate 60 to prevent the coolant and metal chips from moving inward.

[0035] In this embodiment, one end of the first blocking plate 63 extending above the filter box 62 is bent downward, and the height of the inner end of the second blocking plate 64 is lower than the height of the outer end.

[0036] Specifically, as attached Figure 5 As shown, the coolant and metal debris pushed upward by the spiral lifting plate 60 are blocked by the first blocking plate 63. The first blocking plate 63 is bent downward so that the coolant and debris moving upward are pressed downward, allowing the metal debris and coolant to enter the filter box 62. The second blocking plate 64 will not block the coolant and metal debris on the upper side from moving downward.

[0037] In this embodiment, the lower end of the cooling nozzle 43 is spirally bent in the counterclockwise direction.

[0038] Specifically, as attached Figure 7 As shown, during installation and debugging, it is necessary to fill water into the water supply tank 41, the connecting hole 42 and the cooling nozzle 43. According to the use requirements, it is determined whether it is necessary to install a pumping device to pressurize the cooling nozzle 43, so that when the cooling nozzle 43 rotates clockwise, it will squeeze the coolant inside and discharge it downward quickly to perform cooling work.

[0039] In this embodiment, the inner end of the support arm 56 is rotatably connected to the hinge seat through a pin shaft, and a vortex spring is installed on the surface of the hinge seat and outside the pin shaft. The inner end of the vortex spring is installed with the pin shaft at the end of the support arm 56.

[0040] Specifically, as attached Figure 2 As shown, the support arm 56 is supported by the vortex spring so that the support arm 56 remains in an upward position to perform supporting work when in a stationary state. When the support arm 56 rotates, the centrifugal force of the support arm 56 and the equipment installed on its outside causes the support arm 56 to deflect downward to perform the sealing work.

[0041] The working principle and use process of the present invention are as follows: the installation clamping rod 1 is installed and connected to the drill fixture of the machine tool, and the ends of the coolant supply pipe 44 and the drainage pipe 54 are extended to communicate with the inside of the coolant storage tank through a hose, and the coolant supply pipe 44 is connected to the bottom of the coolant storage tank, and the drainage pipe 54 is connected to the top of the coolant storage tank, so that the coolant with a higher temperature is dissipated near the top. When the machine tool is started for drilling, the installation clamping rod 1 is driven to rotate, and the installation clamping rod 1 drives the installation seat body 2 and the drill bit 3 to rotate, and the installation seat body 2 drives the temporary storage box 51 to rotate. When the temporary storage box 51 rotates, it drives the support arm 56 to rotate, and the support arm 56 drives the structure on its outer side to rotate. The centrifugal force generated by the rotation drives the outer end of the support arm 56 to deflect downward. When the support arm 56 deflects, the vortex spring is pressed to deform. The deflection of the support arm 56 drives the middle frame body 57 to deflect outward. The three middle frame bodies 57 deflect outward at the same time to increase the distance between adjacent ones. At this time, the first plug plate 58 and the tail card sleeve 59 that are plugged into each other will slowly disengage. Through the cooperation of the three groups of middle frame bodies 57, the first plug plate 58 and the tail card sleeve 59, the circle formed becomes larger. When the drilling work is not performed, the three groups of middle frame bodies 57, the first plug plate 58 and the tail card sleeve 59 are close to each other, so that the shielding range below the drill bit 3 is small, which is convenient for observing the drilling effect. The three groups of middle frame bodies 57, the first plug plate 58 and the tail card sleeve 59 expand outward and move downward at the same time until the middle frame The supporting balls at the bottom of the body 57 are in contact with the surface of the drilled material, thereby surrounding the outside of the drilled hole to prevent the coolant and debris from splashing outward and causing inconvenience to the subsequent cleaning work. At the same time, the machine tool is controlled to drive the mounting clamping rod 1, the mounting seat body 2 and the drill bit 3 to move downward to perform the drilling work. The cooling nozzle 43 will also revolve during drilling. When the cooling nozzle 43 revolves, the coolant inside it is squeezed out to the lower end by centrifugal force. The squeezed coolant flows to the surface of the drill bit 3 for cooling. The coolant is collected on the surface of the raw material plate and then flows and diffuses outward. At the same time, the debris cut out by the rotation of the drill bit 3 will also move outward under the drive of the coolant. When the middle frame body 57 moves outward, the spiral lifting plate 60 drives the arc-shaped diffusion scraper 61 The arc-shaped diffusion scraper 61 moves outward, so that the inner end of the arc-shaped diffusion scraper 61 is close to the outer side of the drill bit 3, so that when the mounting seat body 2 drives the temporary storage box 51, the support arm 56, the middle frame body 57 and the spiral lifting plate 60 to rotate, the arc-shaped diffusion scraper 61 is also driven to rotate through the spiral lifting plate 60. The rotation of the arc-shaped diffusion scraper 61 pushes the coolant and debris diffused outward to the outside. After the coolant and debris move to the outside, the rotating spiral lifting plate 60 lifts the coolant and debris upward along the inner side of the middle frame body 57 and the tail ferrule 59. The coolant and debris flow into the interior of the filter box 62 and then fall into the interior of the filter screen 7. At this time, the debris is attached to the inner wall of the filter screen 7 through centrifugal force, and the coolant on the surface of the debris passes through the filter screen 7.At this time, the coolant flows to the inner side of the cavity formed by the tail ferrule 59, the filter screen 7, the filter box 62 and the second baffle plate 64 under the action of centrifugal force, thereby separating the coolant and the debris. When the rotation stops after the drilling is completed, the coolant flows to the bottom and flows into the top of the partition plate 52 through the flow opening. The coolant is filtered by the filter plate above the partition plate 52 and then enters the temporary storage box 51 through the partition plate 52 for temporary storage. During the next rotation, the temporary storage box 51 drives the pressurized spiral blade 55 to rotate. The pressurized spiral blade 55 rotates to squeeze the coolant inside the temporary storage box 51 upward. The coolant squeezed upward enters the interior of the annular drainage cover 53, and then is discharged to the outside through the drainage pipe 54 installed on the top, thereby completing the circulation of the coolant. No additional power equipment is required, which is convenient for use.
