Description

Technical Field

[0001] This utility model belongs to the field of drilling equipment technology, specifically relating to a deep hole drilling processing equipment. Background Technology

[0002] Deep holes generally refer to holes with a depth-to-diameter ratio greater than 5. Deep hole drilling is necessary when the hole has a large diameter, a high depth-to-diameter ratio, or is made of difficult-to-machine materials and requires high quality. With the application of cemented carbide in deep hole drill bits, deep hole drilling technology has developed rapidly. Deep hole machining has achieved good levels of surface roughness and precision, and has high productivity. Drilling equipment is typically used to perform deep hole drilling on workpieces.

[0003] Patent CN218836864U discloses "a deep hole drilling equipment, including a main body, a control panel on one side of the front surface of the main body, a drilling machine at the top inside the main body, and a collection groove at the bottom inside the main body. This utility model uses a fixing groove, a tension spring, a connecting column, and a chuck. When the main body is in use, the tension spring inside the fixing groove cooperates with the connecting column to adjust the position of the chuck, thereby using the chuck to clamp and fix the bottom of the workpiece. This method improves the convenience of workpiece fixing."

[0004] Although the filter plates and other components of the existing technology can filter debris from the coolant, after a period of use, debris tends to accumulate on the top of the filter plate, causing large-area coverage and blockage, which reduces the filtration rate of the filter plate. Therefore, it is necessary for the staff to remove the filter plate from the equipment more frequently to clean the top of the filter plate. However, frequent removal and installation of the filter plate is time-consuming and inconvenient, and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a deep hole drilling equipment to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A deep hole drilling equipment includes a body, a porous support plate installed in the middle of the inner side of the body, and a clamping mechanism, a drilling mechanism, a cutting fluid circulation mechanism and a filtering mechanism installed in the body. The filtering mechanism includes a filter screen plate movably installed in the body and a square collection box rotatably connected to the outside of the filter screen plate and movably installed in the body.

[0008] A heat exchange tube is fixedly installed on the bottom side of the machine body. A stirring mechanism is provided at the bottom of the machine body. The stirring mechanism includes a rotating rod that is rotatably installed on the bottom side of the machine body and stirring blades that are fixedly installed on the outer wall of the bottom end of the rotating rod. A square rod is fixedly installed at the bottom of the filter screen plate. The bottom end of the square rod is inserted into a square hole opened at the top of the rotating rod.

[0009] As a further optimization of this utility model, the clamping mechanism includes two electric push rods fixedly installed on both sides of the top of the machine body, and a clamping plate fixedly installed at one end of the electric push rods and abutting against the top of the perforated support plate.

[0010] As a further optimization of this utility model, a baffle is fixedly provided between one side of the machine body and the top edge of the filter screen plate, and folding plates for covering the electric push rod are fixedly provided between both sides of the machine body and the top of the clamping plate. The folding plates are fitted onto the top of the baffle.

[0011] As a further optimization of this utility model, the drilling mechanism includes a cylinder fixedly installed on the top side of the machine body and a drilling head fixedly installed at the bottom of the cylinder.

[0012] As a further optimization of this utility model, the cutting fluid circulation mechanism includes a universal cooling pipe fixedly installed on the top of the machine body for spraying cutting fluid, and a water pump fixedly installed on the bottom of the machine body for sending filtered cutting fluid into the universal cooling pipe through a water pipe.

[0013] As a further optimization of this utility model, a motor for driving the rotating rod to rotate is fixedly installed on the bottom of the outer side of the machine body, and support members for supporting the square collection box are provided on both sides of the inner wall of the machine body.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The filter screen can filter debris from the cutting fluid, and the heat exchange tubes exchange heat and cool the filtered cutting fluid, allowing the filtered and cooled cutting fluid to be recycled. The rotating agitator can both stir the cutting fluid at the bottom of the machine body, so that the cutting fluid can make more uniform contact with the heat exchange tube to improve the heat exchange effect, and drive the filter screen to rotate. Centrifugal force throws the debris on the top of the filter screen into the square collection box for centralized collection, reducing the frequency of disassembling and assembling the filter screen, making it more time-saving and convenient.

[0016] 2. By connecting the square rod with the square hole inside the rotating rod, the filter screen can rotate with the stirring mechanism, and the filter screen and square collection box can be lifted as a whole, so that the filter screen and other components can be removed for easy cleaning. The electric push rod can extend and retract to drive the clamping plate to move. After the clamping plate moves, it can not only clamp and fix the workpiece, but also, with the help of the baffle, push some of the debris generated during the cutting process into the holes of the porous support plate for discharge, reducing the cleaning intensity of the top of the porous support plate for subsequent workers.

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example

[0026] like Figure 1-6As shown, a deep hole drilling equipment includes a body 1, a porous support plate 2, a clamping mechanism, a drilling mechanism, a cutting fluid circulation mechanism, and a filtering mechanism. The body 1 can support and fix the porous support plate 2 and other components. The porous support plate 2 is installed in the middle of the inner side of the body 1. When in use, the workpiece to be processed can be placed in the middle of the top surface of the porous support plate 2. The porous support plate 2 has several holes, which can discharge the cutting fluid and chips during drilling to the bottom of the body 1.

[0027] like Figure 1-3 As shown, the clamping mechanism is installed inside the machine body 1. The clamping mechanism includes two electric push rods 3 fixedly installed on both sides of the top of the machine body 1, and a clamping plate 31 fixedly installed at one end of the electric push rods 3 and abutting against the top of the perforated support plate 2. The clamping plate 31 can be moved by the extension and retraction of the electric push rods 3. After the clamping plate 31 at one end of the two electric push rods 3 moves, it can clamp and fix the workpiece.

[0028] like Figure 1-2 As shown, the drilling mechanism is installed inside the machine body 1. The drilling mechanism includes a cylinder 4 fixedly installed on the top of the inner side of the machine body 1, and a drilling head 41 fixedly installed at the bottom of the cylinder 4. After the cylinder 4 extends and retracts, it will drive the drilling head 41 to rise and fall. After the drilling head 41 is lowered, it can perform deep hole drilling on the workpiece clamped on the top of the multi-hole support plate 2. The drilling head 41 is composed of a mounting base, a motor and a drill rod, etc. The drilling head 41 is a common component of existing drilling equipment. Its internal structure and principle have been disclosed and will not be described in detail here.

[0029] like Figure 1-2 As shown, the cutting fluid circulation mechanism and the filtration mechanism are installed inside the machine body 1. The filtration mechanism can filter the cutting fluid. The cutting fluid circulation mechanism includes a universal cooling pipe 12 fixedly installed on the top of the inner side of the machine body 1 for spraying cutting fluid, and a water pump 11 fixedly installed on the bottom of the inner side of the machine body 1 for sending the filtered cutting fluid into the universal cooling pipe 12 through a water pipe. The universal cooling pipe 12 can spray cutting fluid onto the drilling head 41 and the workpiece during drilling to cool the drilling head 41 and other components. The filtered cutting fluid will flow into the bottom of the inner side of the machine body 1. The water pump 11 can send the filtered cutting fluid from the bottom of the inner side of the machine body 1 into the universal cooling pipe 12, thereby recycling the cutting fluid and reducing resource waste.

[0030] like Figure 1-2 As shown, a heat exchange tube 13 is fixedly installed on the bottom inner side of the machine body 1. Both ends of the heat exchange tube 13 can be connected to external cold water circulation equipment. By exchanging heat between the cutting fluid at the bottom inner side of the machine body 1 and the cold water in the heat exchange tube 13, the temperature of the cutting fluid can be reduced, so that the cutting fluid can be filtered, cooled and recycled.

[0031] like Figure 2 , Figure 4 and Figure 5 As shown, the filtration mechanism includes a filter screen plate 5 movably disposed inside the body 1 and a square collection box 51 rotatably connected to the outside of the filter screen plate 5 and movably disposed inside the body 1. The filter screen plate 5 can filter and block debris in the cutting fluid. The square collection box 51 is provided with a sunken annular collection groove to facilitate the collection of debris. Since the debris of the workpiece is usually heavy, the debris will accumulate at the bottom of the annular collection groove of the square collection box 51, thereby gradually reducing the water in the annular collection groove of the square collection box 51. The filter screen plate 5 is located directly below the porous support plate 2.

[0032] A ring is fixedly provided on the outer side of the filter screen plate 5. The ring of the filter screen plate 5 is rotatably connected to the square collection box 51. The ring can connect the filter screen plate 5 and the square collection box 51, so that the filter screen plate 5 can rotate in the square collection box 51 without detaching. The machine body 1 can limit the matching square collection box 51, so that the square collection box 51 can only slide up and down in the machine body 1.

[0033] like Figure 1-3 As shown, a baffle 21 is fixed between one side of the machine body 1 and the top edge of the filter plate 5. Folding plates 32 for covering the electric push rod 3 are fixed between both sides of the machine body 1 and the top of the clamping plate 31. The folding plates 32 are attached to the top of the baffle 21. The baffle 21 can cover one side of the top of the machine body 1, so that the cutting fluid on the top of the porous support plate 2 will not flow out from one side of the machine body 1.

[0034] After the clamping plate 31 moves, it can work with the baffle 21 to push some of the debris generated during the cutting process into the holes of the porous support plate 2 for discharge, reducing the cleaning intensity of the top of the porous support plate 2 by the subsequent workers. The folding plate 32 can cover and protect the electric push rod 3.

[0035] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the stirring mechanism includes a rotating rod 61 rotatably mounted on the bottom inner side of the body 1, and stirring blades 62 fixedly mounted on the outer wall of the bottom end of the rotating rod 61. A square rod 52 is fixedly mounted on the bottom of the filter screen plate 5, and the bottom end of the square rod 52 is inserted into a square hole opened at the top of the rotating rod 61. A motor 6 for driving the rotating rod 61 to rotate is fixedly mounted on the bottom outer side of the body 1. Support members 14 for supporting the square collection box 51 are provided on both sides of the inner wall of the body 1. The rotating rod 61 is fixedly connected to the top of the output end of the motor 6. A sealing element can be provided between the output end of the motor 6 and the connection between the motor 6 and the body 1.

[0036] The support member 14 includes a horizontal plate fixed on both sides of the inner wall of the body 1, and a spring fixed on the top of the horizontal plate and abutting against the bottom of the square collection box 51. The support member 14 can provide auxiliary support for the filter mechanism such as the square collection box 51, thereby improving the stability of the filter mechanism. A door is provided on one side of the body 1, which can be opened to inspect and maintain the inside of the body 1. The motor 6 is an existing adjustable speed motor, which is public technology and will not be described in detail here.

[0037] By connecting the square rod 52 with the square hole inside the rotating rod 61, the rotating rod 61 can be connected to the filter screen plate 5. When the rotating rod 61 rotates, the filter screen plate 5 will rotate accordingly. When the motor 6 runs at low speed, it will drive the stirring blade 62 to rotate, and through the connection of the square rod 52, it will drive the filter screen plate 5 to rotate accordingly. After the stirring blade 62 rotates, it can agitate the cutting fluid at the bottom of the machine body 1, so that the cutting fluid can make more uniform contact with the heat exchange tube 13 to improve the heat exchange effect. At this time, the filter screen plate 5 rotates slowly at low speed to filter the cutting fluid.

[0038] When the motor 6 rotates at high speed, it will drive the filter screen plate 5 to rotate as well. After the filter screen plate 5 rotates at high speed, the centrifugal force will throw the debris on the top of the filter screen plate 5 into the square collection box 51 for centralized collection. This reduces the frequency of subsequent disassembly and cleaning of the filter screen plate 5 and saves more time. By opening the box door and lifting the filter screen plate 5 and the square collection box 51 as a whole, the square rod 52 can be disengaged from the square hole of the rotating rod 61, and the filter screen plate 5 and other components can be removed as a whole, which is more convenient.

[0039] It should be noted that, when using this deep hole drilling equipment, the workpiece to be processed is first placed in the middle of the top surface of the multi-hole support plate 2. The extension and retraction of the electric push rod 3 can drive the clamping plate 31 to move. After the clamping plate 31 at one end of the two electric push rods 3 moves, it can clamp and fix the workpiece. Then, the extension and retraction of the cylinder 4 is controlled to drive the drilling head 41 to rise and fall. After the drilling head 41 is lowered, it can perform deep hole drilling on the workpiece clamped on the top of the multi-hole support plate 2.

[0040] At the same time, the water pump 11 is turned on, which can send the cutting fluid from the bottom of the inner side of the machine body 1 into the universal cooling pipe 12. The universal cooling pipe 12 can spray the cutting fluid onto the drilling head 41 and the workpiece during drilling to cool down the drilling head 41 and other components. The cutting fluid filtered by the filter screen 5 will flow back into the bottom of the inner side of the machine body 1 and exchange heat with the heat exchange pipe 13 to cool down, so that the cutting fluid can be recycled and reduced waste of resources.

[0041] Then, the motor 6 is turned on. After the motor 6 runs, it will drive the stirring blade 62 to rotate, and through the connection of the square rod 52, it will drive the filter screen plate 5 to rotate as well. After the stirring blade 62 rotates, it can agitate the cutting fluid at the bottom of the machine body 1, so that the cutting fluid can make more uniform contact with the heat exchange tube 13 to improve the heat exchange effect. After the filter screen plate 5 rotates, it will use centrifugal force to throw the debris on the top of the filter screen plate 5 into the square collection box 51 for centralized collection, which reduces the frequency of subsequent disassembly and assembly of the filter screen plate 5 for cleaning, making it more time-saving and convenient.

[0042] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
