A safety protection structure for machining

Abstract

The present invention provides a safety protection structure for machining, which relates to the technical field of machining. The safety protection structure for machining includes a mounting and clamping rod, a cooling device with an automatic pressurization function, and a protection device for blocking and collecting chips and coolant generated during the machining process. A clamping groove for mounting and connecting with the equipment is formed at the top of the mounting and clamping rod, and a mounting seat body is installed at the bottom of the mounting and clamping rod. During the drilling process of this safety protection structure for machining, the coolant diffuses outward from the drill bit position, and at the same time, the chips will also move outward under the drive of the coolant, so that the chips are away from the drill bit, preventing the increase of the wear of the drill bit. The high-temperature coolant just after cooling and the relatively high-temperature chips just cut off are quickly discharged outward, improving the cooling efficiency of the cutting and drilling position of the drill bit and enhancing the protection effect on the drill bit.

Description

Technical Field

[0001] The present invention relates to the technical field of machining, and specifically to a safety protection structure for machining. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. For example, the drilling process of raw materials is generally carried out by a drill bit. During machining, in order to prevent the drill bit from overheating and being damaged, coolant is usually used to cool the drill bit. And during the drilling process, a large amount of metal chips will be generated. With the high-speed rotation of the drill bit, the chips and coolant will splash outwards.

[0003] The invention patent with the 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 and folding protective cylinder, and a drill bit balancing mechanism. The drilling machine uses the drill bit to drive the drill bit clamping piece, so that when the arc-shaped piece rotates, it drives the drilling and grinding layer to grind the edge of the hole, avoiding damage to the contact person by the edge of the hole. The design of the drill bit clamping piece is used to assist in balancing the rotation stability of the drill bit and grinding the edge of the hole. By rotating the negative pressure fan to generate negative pressure attraction, the chips are concentrated into the telescopic and folding protective cylinder, avoiding the chips from scattering everywhere, and can also cool the drill bit and reduce the heat loss of the drill bit.

[0004] During the use of this drilling machine, it can only perform hole drilling work with a single depth, resulting in low adaptability. When adjusting the drilling depth, it is necessary to stop the machine for adjustment, which brings inconvenience to the use. And when cooling, water cooling cannot be used, and only air cooling is used for cooling, resulting in poor cooling effect. And during the cooling process, the air flow flows from the outside to the inside and then drives the chips to move upwards. However, the air flow flowing towards the middle position will lose a large amount of kinetic energy under the action of mutual impact, resulting in the chips being concentrated near the drill bit position, affecting the chip cleaning efficiency, and the chip cleaning effect is poor. The chips concentrated near the drill bit will also affect the normal operation of the drill bit, and the contact between the chips and the drill bit will accelerate the wear of the drill bit. Generally, water-cooled drill bits cannot quickly recover the chips and coolant during operation, resulting in the coolant and chips remaining on the surface of the raw material, bringing inconvenience to subsequent processing, and the coolant cannot be recycled, increasing the processing operation cost. Summary of the Invention

[0005] (I) Technical Problems to be Solved

[0018] (III) Beneficial effects

[0019] The present invention provides a safety protection structure for mechanical processing. It has the following beneficial effects:

[0020] 1. In the process of drilling processing of this safety protection structure for mechanical processing, the coolant diffuses outward from the drill bit position, and at the same time, the debris will also move outward under the drive of the coolant, so that the debris is far away from the drill bit, preventing the increase of the wear of the drill bit. The high-temperature coolant just cooled and the relatively high-temperature debris just cut off are quickly discharged outward, improving the cooling efficiency of the cutting and drilling position of the drill bit and the protection effect on the drill bit.

[0021] 2. In this safety protection structure for mechanical processing, the cooling spray head is designed in a spiral shape. During rotation, the coolant inside the cooling spray head will automatically drain downward, thereby increasing the flow rate of the coolant through centrifugal force. At the same time, when the arc-shaped diffusion scraper rotates, it will also push the coolant outside the drill bit to flow quickly outward, accelerating the flow rate of the coolant through automatic pressurization, and improving the cooling efficiency and cooling effect of the coolant on the drill bit.

[0022] 3. In this safety protection structure for mechanical processing, after the coolant and debris enter the filter box along the spiral lifting plate and fall above the filter screen, then as they rotate, the coolant on the surface of the debris penetrates through the filter screen and accumulates in the cavity outside the filter screen inside the filter box. Then when the work stops, the debris stays and accumulates downward inside the filter screen, and the filtered coolant will flow downward through the gap between adjacent lower support partitions and then flow into the upper part of the partition plate through the flow opening. After secondary filtration by the filter plate above the partition plate, the coolant enters the sealed cavity inside the temporary storage box. During use, it will automatically filter and separate the coolant, and will improve the separation effect of the coolant on the surface of the debris through the centrifugal force of rotation, improving the filtering effect of the coolant and preventing waste.

[0023] 4. For the safety protection structure for machining, the filtered coolant inside the temporary storage box is pressurized by the push of the pressurized spiral blade, and the coolant is pushed upward by the pressurized spiral blade and enters 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. There is no need for multiple pumping devices to carry out the drainage work. During machining, the ends of the drainage pipe and the coolant supply pipe are extended into the coolant tank through a hose, and the coolant can complete the circulating flow work by itself, reducing the overall use cost of the equipment. Moreover, the supply and recovery of the coolant will automatically stop when the rotation stops, without adding additional control equipment, which is convenient for use.

[0033] The present invention will be further described below with reference to the drawings and embodiments.

[0034] Please refer to Figures 1-8, the present invention provides a technical solution: a safety protection structure for machining, including an installation clamping rod 1, a cooling device 4 with an automatic pressure boosting function, and a protection device 5 for blocking and collecting chips and coolant generated during the machining process. A clamping groove for installation connection with the equipment is provided at the top of the installation clamping rod 1. A mounting seat body 2 is installed at the bottom of the installation clamping rod 1. A drill bit 3 for drilling is installed at the bottom of the mounting seat body 2. A cooling device 4 for spraying coolant on the surface of the drill bit 3 is provided at the top of the mounting seat body 2. A protection device 5 for blocking and collecting chips and coolant generated during the machining process is provided on the outside of the mounting seat body 2.

[0035] In this embodiment, the cooling device 4 includes a water supply tank 41, a communication hole 42, a cooling spray head 43, and a coolant supply pipe 44. The water supply tank 41 is installed at the top of the mounting seat body 2 and is located outside the installation clamping rod 1. The communication hole 42 is opened on the surface of the mounting seat body 2 below the water supply tank 41. The cooling spray head 43 is installed at the bottom of the mounting seat body 2 and is located below the communication hole 42. A sealing ring seat is rotatably installed on the outer wall of the water supply tank 41 through a bearing. The coolant supply pipe 44 is installed on the outside of the sealing ring seat, and the coolant supply pipe 44 is communicated with the inside of the water supply tank 41.

[0036] Specifically, as shown in the appendix Figure 2 When the water supply tank 41 rotates, the coolant supply pipe 44 remains relatively stationary and does not rotate. When the mounting seat body 2 rotates, it will drive the cooling device 4 to work. Through the cooling device 4, coolant is sprayed with sub-boost pressure to cool down the drilling position of the drill bit 3.

[0037] In this embodiment, the protection 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 body 57, a first plug board 58, a tail clamping sleeve 59, a spiral lifting plate 60, an arc-shaped diffusion scraper 61, a filter box 62, a first baffle plate 63, a second baffle plate 64, and a lower support partition plate 65. The temporary storage box 51 is installed on the outer surface of the mounting seat body 2. The partition plate 52 is installed at an upper position inside the temporary storage box 51. The annular drainage cover 53 is installed on the top of the temporary storage box 51. A circular sealing cover is installed on the top of the annular drainage cover 53 through a bearing. The drainage pipe 54 is installed on the top of the circular sealing cover. The positions of the coolant supply pipe 44 and the drainage pipe 54 that are close to each other are bundled and fixed by straps. The bottom of the pressurized spiral blade 55 is installed on the inner wall of the bottom of the temporary storage box 51, and the top of the pressurized spiral blade 55 is installed on the bottom of the partition plate 52. An inwardly concave notch is provided on the outer side of the temporary storage box 51. The inner end of the support arm 56 is installed inside the notch through a hinge seat, and the outer end of the support arm 56 is hinged to the inner wall of the middle frame body 57 through a hinge. The first plug board 58 is installed on the clockwise side of the middle frame body 57, and the tail clamping sleeve 59 is installed on the counterclockwise side of the middle frame body 57. The spiral lifting plate 60 for collecting the coolant and debris upward is installed on the inner side walls of the middle frame body 57 and the tail clamping sleeve 59. The arc-shaped diffusion scraper 61 for scraping the coolant and debris outward is installed at the bottom end of the spiral lifting plate 60. A filter box 62 for filtering the debris in the coolant is installed inside the tail clamping sleeve 59 and at a position above the upper end of the spiral lifting plate 60. A first baffle plate 63 for preventing the coolant above the spiral lifting plate 60 from splashing upward is installed on the inner wall of the tail clamping sleeve 59 above the spiral lifting plate 60. A second baffle plate 64 for preventing the coolant from splashing upward is installed inside the tail clamping sleeve 59 and inside the filter box 62. A lower support partition plate 65 is installed on the inner wall of the bottom of the filter box 62. A flow opening is provided on the inner side wall of the filter box 62 and inside the lower support partition plate 65.

[0038] Specifically, as shown in the attached Figure 2 - attached Figure 6As shown, the protective device 5 is used to clean the metal chips generated during drilling and the high-temperature coolant after cooling. The arc-shaped diffusion scraper 61 is an arc-shaped rod, and the arc-shaped diffusion scraper 61 is located outside the drill bit 3. When the middle frame 57 drives the arc-shaped diffusion scraper 61 to expand outward through the spiral lifting plate 60, the end of the arc-shaped diffusion scraper 61 far from the spiral lifting plate 60 approaches the outside of the drill bit 3, so that the arc-shaped diffusion scraper 61 can automatically approach the drill bit 3 during drilling to clean the coolant and chips outside the drill bit 3. The middle frame 57 and the tail chuck 59 are made of rigid transparent materials, and the first insertion plate 58 is made of elastic plastic. When the middle frame 57 and the tail chuck 59 expand outward, the first insertion plate 58 can move outward along the inside of the tail chuck 59 and deform to expand along with the movement, preventing the expansion of the middle frame 57 and the tail chuck 59 from being hindered.

[0039] In this embodiment, a filter screen 7 is installed on the top of the lower support partition 65. The cross-section of the filter screen 7 is L-shaped, and the filter screen 7 is clamped at the position inside the lower support partition 65 and the second baffle 64. The flow opening opened on the inner side 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 at the position above the one-way valve on the top of the partition plate 52.

[0040] Specifically, as shown in the attached Figure 3 and the attached Figure 8 As shown, the metal chips falling into the filter box 62 are preliminarily filtered through the filter screen 7, and as the filter box 62 rotates, the metal chips will adhere to the outer surface of the filter screen 7, and then the metal chips are separated from the coolant by centrifugal force.

[0041] In this embodiment, support balls for reducing friction are inlaid at the bottom of the middle frame 57. Gaskets for water blocking are installed at the bottoms of the first insertion plate 58 and the tail chuck 59, and the plane where the bottom of the gasket is located is higher than the plane where the bottom of the support ball is located.

[0042] Specifically, as shown in the attached Figure 6 As shown, the gasket is woven from wear-resistant hemp rope fibers. The gasket fabric has fiber gaps. The gasket can be compressed by pressing. After the gasket is compressed, the support ball contacts the drilling raw material plane for rolling support to reduce friction.

[0043] In this embodiment, the pressurizing spiral blade 55 is spiral-shaped. The bottom of the annular drainage cover 53 is communicated with the cavity above the pressurizing spiral blade 55. A total of three pressurizing spiral blades 55 are evenly installed on the bottom inner wall of the temporary storage box 51.

[0044] Specifically, as shown in the attached Figure 4As shown, the annular drainage cover 53 is connected to the internal cavity of the temporary storage box 51. When the pressurized spiral blade 55 rotates, it will push the coolant in the internal cavity of the temporary storage box 51 upward and into the inside of the annular drainage cover 53 to achieve the pressurizing effect, and then the coolant is discharged through the drainage pipe 54.

[0045] In this embodiment, the spiral lifting plate 60 is spiral, and the height of the inner end of the spiral lifting plate 60 is higher than that of the outer end.

[0046] Specifically, as shown in the appendix Figure 5 As shown, the spiral lifting plate 60 is used to lift the metal debris and coolant at the bottom upward, and during the lifting process, the coolant and metal debris will be located on the outer side of the spiral lifting plate 60 to prevent the coolant and metal debris from moving inward.

[0047] In this embodiment, one end of the first baffle plate 63 extending above the filter box 62 is bent downward, and the height of the inner end of the second baffle plate 64 is lower than that of the outer end.

[0048] Specifically, as shown in the appendix Figure 5 As shown, the first baffle plate 63 blocks the coolant and metal debris pushed upward by the spiral lifting plate 60. The downward bending of the first baffle plate 63 presses the upward moving coolant and debris downward, so that the metal debris and coolant enter the inside of the filter box 62, and the second baffle plate 64 does not block the downward movement of the upper coolant and metal debris.

[0049] In this embodiment, the lower end of the cooling nozzle 43 is spirally bent in the counterclockwise direction.

[0050] Specifically, as shown in the appendix Figure 7 As shown, during installation and debugging, the water supply tank 41, the communication hole 42, and the inside of the cooling nozzle 43 need to be filled with water. According to the usage requirements, it is judged 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 for cooling work.

[0051] 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 piece is installed on the surface of the hinge seat at a position outside the pin shaft, and the inner end of the vortex spring piece is installed on the pin shaft at the end of the support arm 56.

[0052] Specifically, as shown in the appendix Figure 2 As shown, the support arm 56 is supported by the vortex spring piece, so that the support arm 56 maintains an upward state for support work when it is in a static state. When the support arm 56 rotates, the centrifugal force of the support arm 56 and the equipment installed on its outer side causes the support arm 56 to deflect downward for capping work.

[0053] Working principle and usage process of the present invention: Install and connect the installation clamping rod 1 with the drill bit fixture of the machine tool. Extend the ends of the coolant supply pipe 44 and the drainage pipe 54 to communicate with the inside of the coolant storage tank through a hose, and the coolant supply pipe 44 leads to the bottom of the coolant storage tank, while the drainage pipe 54 leads to a position near the top of the coolant storage tank, so that the coolant with a higher temperature dissipates heat at the position near the top. When starting the machine tool for drilling work, it drives the installation clamping rod 1 to rotate. The installation clamping rod 1 drives the installation seat body 2 and the drill bit 3 to rotate. 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. The support arm 56 drives the structure outside it 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, it presses the vortex spring 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 simultaneously, increasing the distance between adjacent ones. At this time, the first insertion plate 58 and the tail clamping sleeve 59 that are inserted into each other will slowly separate. Through the cooperation of the three groups of middle frame bodies 57, the first insertion plate 58 and the tail clamping sleeve 59, the enclosed circle becomes larger. When drilling work is not carried out, the three groups of middle frame bodies 57, the first insertion plate 58 and the tail clamping sleeve 59 approach each other, resulting in a smaller shielding range below the drill bit 3, which is convenient for observing the drilling effect. While the three groups of middle frame bodies 57, the first insertion plate 58 and the tail clamping sleeve 59 expand outward, they also move downward until the support balls at the bottom of the middle frame body 57 contact the surface of the drilling material, thereby surrounding the outside of the drill hole to prevent the coolant and debris from splashing outward, which brings inconvenience to the subsequent cleaning work. At the same time, control the machine tool to drive the installation clamping rod 1, the installation seat body 2 and the drill bit 3 to move downward for drilling work. When drilling, the cooling nozzle 43 will also revolve. When the cooling nozzle 43 revolves, the coolant inside it is squeezed and discharged downward by the centrifugal force. The squeezed coolant flows to the surface of the drill bit 3 for cooling work. The coolant gathers on the surface of the raw material plate and then flows outward and diffuses. At the same time, the debris cut 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, it drives the arc-shaped diffusion scraper 61 to move outward through the spiral lifting plate 60, so that the inner end of the arc-shaped diffusion scraper 61 near the drill bit 3. Thus, when the installation 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, it will also drive the arc-shaped diffusion scraper 61 to rotate through the spiral lifting plate 60. The arc-shaped diffusion scraper 61 rotates to push the coolant and debris that diffuse 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 sides of the middle frame body 57 and the tail clamping sleeve 59. The coolant and debris flow into the internal part of the filter box 62 and then fall onto the filter screen 7. At this time, the centrifugal force makes the debris adhere to the inner side wall of the filter screen 7, and the coolant on the surface of the debris penetrates through the filter screen 7.At this time, the coolant flows to the inner side of the cavity formed by the tail bushing 59, the filter screen 7, the filter box 62 and the second baffle 64 under the action of centrifugal force, so as to separate the coolant and debris. When the rotation stops after the drilling is completed, the coolant flows downward and enters above the partition plate 52 through the flow opening. The coolant passes through the filter plate above the partition plate 52 and enters the inside of the temporary storage box 51 through the partition plate 52 for temporary storage. During the next rotation operation, the temporary storage box 51 drives the pressurizing spiral blade 55 to rotate. The pressurizing spiral blade 55 rotates to squeeze the coolant inside the temporary storage box 51 upward. The coolant squeezed upward enters the inside of the annular drainage cover 53 and then is discharged outward through the drainage pipe 54 installed at the top, thus completing the circulation work of the coolant. There is no need to use additional power equipment, which is convenient for use.

[0054] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
