Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, and more specifically, it relates to a positioning and cooling device for deep hole drilling of multi-layer laminated sheets. Background Technology

[0002] In the field of sheet metal processing, multi-layer laminated boards are widely used in many industries such as construction, furniture, and machinery manufacturing due to their high strength and good material composite properties. Deep hole drilling of multi-layer laminated boards is a key link in its processing flow, which has extremely high requirements for processing accuracy, efficiency and equipment stability. It also faces many technical challenges. During the through-hole processing, the drill bit and the material will heat up, so cooling treatment is required.

[0003] Application number CN201820377077.4 discloses a drilling device for multilayer boards, including a support frame and a drill housing. The support frame has horizontally mounted base plates at both its left and right ends. The drill housing has a handle horizontally mounted on its top left side, with ventilation holes on the handle. From left to right, a blower A switch, a blower B switch, and an LED light switch are sequentially mounted on the top of the drill housing. A fixing block is horizontally mounted in the middle of the left side of the drill housing. This invention connects the drill housing to the support frame via a crossbar, allowing the drill housing to move up and down within the support frame. This prevents the drilled hole from tilting due to the drill housing not being held vertically during vertical movement. Simultaneously, the support frame protects the drill bit, preventing exposure and potential safety hazards. This device is practical and suitable for widespread application.

[0004] Based on the above patent searches and understanding of the applications of deep hole drilling in existing multilayer laminated plates:

[0005] Drilling generates a lot of heat. Existing drilling cooling methods mostly involve blowing air in one direction, which cannot cool the drill bit comprehensively and in a timely manner. This may cause the drill bit to wear out faster due to overheating, affecting its service life and drilling quality.

[0006] Drilling generates a lot of debris and dust. Existing dust removal methods have limited coverage and cannot remove dust in all directions, which affects the processing environment and may also pose a threat to the health of operators. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a positioning and cooling device for deep hole drilling of multi-layer stacked plates. This device solves the problems of existing drilling cooling methods, which mostly rely on unidirectional airflow and cannot comprehensively and promptly cool the drill bit. This can lead to the drill bit overheating and accelerated wear, affecting its service life and drilling quality. Additionally, drilling generates a lot of debris and dust, and the existing dust removal methods have limited coverage and cannot remove dust in all directions, which affects the processing environment and may also threaten the health of operators.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A positioning and cooling device for deep hole drilling of multi-layer stacked plates includes a processing table; a horizontal frame is fixedly installed at the top of the processing table, the horizontal frame is located in front of a lifting frame, a drilling machine is slidably connected to the upper front of the lifting frame, an mounting frame is provided below the drilling machine, a through slot is opened at the top middle and rear of the mounting frame, the drill bit of the drilling machine is located in the middle of the through slot of the mounting frame, a toothed ring is rotatably connected to the bottom outer side of the through slot of the mounting frame, and an inclined cooling fan is provided at the bottom edge of the toothed ring, the cooling fan is located outside the drill bit of the drilling machine.

[0010] According to one embodiment of the present invention, a motor A is fixedly installed at the left front position of the transverse frame, and a sliding frame is slidably mounted at the front upper position of the transverse frame.

[0011] According to one embodiment of the present invention, a threaded hole is provided at the middle position of the side of the sliding frame, and the shaft of motor A is provided with threads.

[0012] According to one embodiment of the present invention, the thread of motor A is located in the threaded hole of the sliding frame, the front end of the sliding frame is longitudinally slidably connected to the lifting frame, the rear end of the top of the lifting frame is provided with a threaded hole, motor B is fixedly installed at the top of the sliding frame, the shaft of motor B is provided with a thread, and the shaft of motor B is located in the threaded hole of the lifting frame.

[0013] According to one embodiment of the present invention, a motor C is fixedly installed at the front center position of the mounting frame, and a gear component is fixedly connected to the bottom shaft of the motor C. The rear position of the gear component meshes with the front position of the gear ring component.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By using motor A to drive the sliding frame to slide laterally on the transverse frame, and motor B to drive the lifting frame to slide longitudinally at the front end of the sliding frame, the transverse and longitudinal positions of the drilling machine can be precisely adjusted to ensure accurate drilling position and meet the high precision requirements of deep hole drilling of multi-layer stacked plates.

[0016] 2. Motor C drives the gear component to rotate, which in turn drives the gear ring component to rotate, causing the cooling fan to move in a circular motion around the drill bit. This cools the drill bit from multiple angles, effectively removing the heat generated during drilling, reducing drill bit temperature, minimizing wear, extending its service life, and ensuring stable drilling quality.

[0017] 3. As the cooling fan rotates around the drill bit, it not only cools the drill bit but also blows away the debris and dust generated during drilling from different directions, achieving all-round dust removal, improving the processing environment, and protecting the health of operators.

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a positioning and cooling device for deep hole drilling of multi-layer stacked plates, including a processing table 1; a horizontal frame 101 is fixedly installed at the top of the processing table 1, the horizontal frame 101 is located in front of the lifting frame 105, a drilling machine 106 is slidably connected to the upper front of the lifting frame 105, an mounting frame 2 is provided below the drilling machine 106, a through groove is opened at the middle rear of the top of the mounting frame 2, the drill bit of the drilling machine 106 is located in the middle of the through groove of the mounting frame 2, a toothed ring 201 is rotatably connected to the outer bottom of the through groove of the mounting frame 2, and an inclined cooling fan 204 is provided at the bottom edge of the toothed ring 201, the cooling fan 204 is located outside the drill bit of the drilling machine 106.

[0029] Among them, a motor A102 is fixedly installed at the front left position of the transverse frame 101, and a sliding frame 103 is slidably mounted at the upper front position of the transverse frame 101.

[0030] The sliding frame 103 has a threaded hole in the middle of its side. The shaft of the motor A102 is threaded and the thread of the motor A102 is located in the threaded hole of the sliding frame 103. The front end of the sliding frame 103 is longitudinally slidably connected to the lifting frame 105. The rear end of the top of the lifting frame 105 has a threaded hole. The top of the sliding frame 103 is fixedly installed with a motor B104. The shaft of the motor B104 is threaded and is located in the threaded hole of the lifting frame 105.

[0031] Among them, a motor C202 is fixedly installed at the front center of the mounting bracket 2, and a gear component 203 is fixedly connected to the bottom shaft of the motor C202. The rear position of the gear component 203 meshes with the front position of the gear ring component 201.

[0032] When using:

[0033] The multi-layer stacked plate that needs to be drilled for deep holes is placed and fixed above the processing table 1;

[0034] Start motor A102. Since the shaft of motor A102 is threaded and located in the threaded hole of sliding frame 103, when motor A102 rotates, it will drive sliding frame 103 to slide laterally on transverse frame 101, thereby adjusting the transverse position of drilling machine 106 so that it is aligned with the transverse position of the multi-layer stacked board that needs to be drilled. Then, start motor B104 to control lifting frame 105 to slide longitudinally at the front end of sliding frame 103, adjust the height of drilling machine 106 so that it is in a suitable longitudinal position.

[0035] Start the drilling machine 106, and the drill bit of the drilling machine 106 performs deep hole drilling on the multi-layer stacked plate through the through slot of the mounting frame 2.

[0036] During the drilling process, the motor C202 is started. The bottom shaft of the motor C202 drives the gear 203 to rotate. Since the rear position of the gear 203 meshes with the front position of the gear ring 201, the gear 203 drives the gear ring 201 to rotate on the outside of the bottom of the slot of the mounting frame 2. The cooling fan 204 with the inclined design at the bottom edge of the gear ring 201 rotates with the gear ring 201 and moves in a circle around the drill bit of the drilling machine 106. It blows air to cool the drill bit from multiple angles, removes the heat generated by drilling in time, and also has the effect of all-round dust removal.

[0037] After drilling is completed, turn off the drilling machine 106, motor A102, and motor C202, reset the lifting frame 105 and sliding frame 103, and remove the processed multi-layer stacked board.
