[0001] This invention relates to the field of machining equipment, and in particular to a machine tool. Background Technology

[0002] Machine tools are machines used to manufacture machinery and equipment.

[0024] like Figure 2 and Figure 3 As shown:

[0025] A machine tool includes a machine tool body and auxiliary equipment for silencing and cleaning the machine tool. The auxiliary equipment includes a soundproof enclosure 101, two side plates 102 fixedly connected to the soundproof enclosure 101, a rack 103 and a base plate 104 fixedly connected to each side plate 102, two support blocks 105 slidably connected to the two racks 103 respectively, two clamping plates 108 slidably connected to the two base plates 104 respectively, each lead screw 107 slidably connected between the corresponding support block 105 and the clamping plate 108, two first gears 106 rotatably connected to the lower ends of the two support blocks 105 respectively, each first gear 106 meshing with the corresponding rack 103, each lead screw 107 rotating within the corresponding first gear 106, a first rotary motor disposed between one of the first gears 106 and the corresponding support block 105, and a second rotary motor disposed between one of the lead screws 107 and the corresponding support block 105.

[0026] The first rotary motor is driven to work, thereby driving the first gear 106 to rotate on the support plate. The first gear 106 meshes with the corresponding rack 103, thereby driving the support block 105 to slide on the upper end of the rack 103. The support block 105 then drives the lead screw 107 to move. The lower end of the lead screw 107 is rotatably connected to the clamping plate 108, thereby causing the lead screw 107 to drive the clamping plate 108 to slide together on the base plate 104, thereby adjusting the horizontal position of the tool holder 202.

[0027] The second rotary motor is driven to operate, causing the lead screw 107 to rotate between the corresponding support block 105 and the clamping plate 108. The lead screw 107 is threadedly connected to the horizontal plate 201, so that one lead screw 107 drives the horizontal plate 201 to move in the vertical direction, while the other lead screw 107 provides support and assistance to the horizontal plate 201, thereby minimizing the vibration of the horizontal plate 201 during movement and preventing the auxiliary tools installed on the horizontal plate 201 from bumping into the machine tool, thus protecting the machine tool.

[0028] like Figure 3-5 As shown:

[0029] A horizontal plate 201 is threaded between two lead screws 107. A tool holder 202 is slidably connected to the horizontal plate 201. A first electric push rod is provided between the tool holder 202 and the horizontal plate 201. A conversion disc 203 is rotatably connected to the lower side of the tool holder 202. A gripper 204 is fixedly connected to the conversion disc 203. A third rotary motor is provided between the conversion disc 203 and the tool holder 202.

[0030] By driving the third rotary motor, the conversion disk 203 rotates under the tool holder 202, causing the chuck 204 to rotate to the working position. The first electric push rod then drives the tool holder 202 to slide on the horizontal plate 201, further adjusting the position of the tool holder 202 and thus more precisely positioning the chuck 204. Older machine tools are still used in many places, but due to limited worktable space, they cannot meet current processing requirements. Therefore, the chuck 204 is used to hold various auxiliary tools, such as coolant spray pipes. The position of the chuck 204 can be adjusted as required so that coolant is sprayed directly onto the workpiece at the appropriate location. With improved cooling performance, the cutting speed and feed rate can be appropriately increased. The chuck 204 can also be used to hold various fixtures and measuring tools to assist machine tool processing, thereby improving the overall performance of the machine tool.

[0031] like Figure 5 As shown:

[0032] The sleeve 205 is rotatably connected inside the conversion disc 203, and the cleaning brush 206 is key-connected inside the sleeve 205.

[0033] When the machine tool is working, it cuts the workpiece, generating a large amount of iron filings. These filings accumulate on the worktable, covering the workpiece and affecting its machining accuracy. After machining, the residual iron filings can affect the positioning accuracy of the next workpiece to be machined, thus requiring the worktable to be cleaned. The third rotary motor is driven to rotate, causing the conversion disk 203 to rotate below the tool holder 202, which in turn moves the sleeve 205 into the working position. This causes the sleeve 205 to drive the cleaning brush 206 into the working position. Subsequently, as the tool holder 202 reciprocates on the horizontal plate 201, the sleeve 205 rotates within the conversion disk 203, which in turn drives the cleaning brush 206 to rotate, thereby cleaning and maintaining the machine tool's worktable to improve the machine tool's service life and machining accuracy.

[0034] like Figure 5 As shown:

[0035] The support arm 207 is fixed to the tool seat 202, and the second gear 208 is rotatably connected to the support arm 207. The second gear 208 is simultaneously engaged with the cross plate 201 and the sleeve 205.

[0036] The drive conversion disc 203 rotates. When the conversion disc 203 drives the sleeve 205 to the working position, the second gear 208 mounted on the tool holder 202 via the support arm 207 contacts the upper end of the sleeve 205 and engages in a transmission connection. The upper part of the second gear 208 engages in a transmission connection with the horizontal plate 201. Thus, when the drive tool holder 202 slides on the horizontal plate 201, the horizontal plate 201 drives the second gear 208 to rotate. The second gear 208 simultaneously drives the sleeve 205 to rotate within the conversion disc 203, thereby causing the sleeve 205 to drive the cleaning brush 206 to rotate. The cleaning brush 206 rotates forward and can remove iron filings from the gaps in the workbench, thereby improving the cleaning ability of the cleaning brush 206.

[0037] like Figure 6 and Figure 7 As shown:

[0038] Two filter plates 301 are rotatably connected to two side plates 102 respectively, and two baffles 302 are slidably connected to two filter plates 301 respectively.

[0039] After the machine tool is wrapped with auxiliary equipment, the two filter plates 301 are flipped downwards. Each filter plate 301 has a notch machined on it, so that the two filter plates 301 fix the base of the machine tool during the fall. At this time, the notch just locks the machine tool. The filter plate 301 and the side plate 102 are at a certain angle, but the two filter plates 301 cannot contact each other, which would cause the iron filings to leak. Therefore, the two baffles 302 are pushed so that the two baffles 302 slide on the two filter plates 301 respectively, so that they contact each other above the two filter plates 301, thereby blocking the gap between the two filter plates 301, so that the iron filings fall onto the two baffles 302 and slide onto the filter plates 301, thereby collecting the iron filings.

[0040] The parts of the two filter plates 301 and the two baffles 302 that come into contact with the machine tool are all equipped with soft rubber strips, which ensures the sealing of the filter plates 301 to the machine tool, prevents iron filings from leaking, and prevents the machine tool from colliding with auxiliary equipment due to working vibration during operation, thereby generating noise and achieving the purpose of quiet operation.

[0041] like Figure 7 As shown:

[0042] Both filter plates 301 are machined with multiple filter holes 303, and multiple sedimentation strips 304 are fixedly attached to each filter plate 301.

[0043] When machining a workpiece, coolant is sprayed onto both the workpiece and the cutting tool to cool them down, protect the tool, and ensure machining accuracy. As the coolant flows over the workpiece surface, it carries iron filings to the filter plate 301. The filter holes 303 machined on the filter plate 301 separate the iron filings from the coolant, allowing the coolant to be recycled and facilitating the recovery of the iron filings. Some iron filings are too small, so a sedimentation bar 304 is fixed above each row of filter holes 303. When the coolant carrying the iron filings flows over the sedimentation bar 304, a buffer zone is formed above the sedimentation bar 304, causing the iron filings to settle. The coolant then flows through the sedimentation bar 304 and out of the filter holes 303, further filtering the coolant and preventing the pipes from becoming clogged.

[0044] like Figure 8 and Figure 9 As shown:

[0045] Two scrapers 401 are slidably connected to two filter plates 301 respectively. Each scraper 401 is fixed with a cutter 402 and a pull rod 403. Each extrusion plate 404 is in contact with the corresponding side plate 102 and filter plate 301. Each extrusion plate 404 is provided with a through hole 405.

[0046] When too much iron filings accumulate on the filter plate 301 and too much iron filings and sludge are deposited on the sedimentation bar 304, the filter plate 301 needs to be cleaned. This drives the pull rod 403, which passes through the soundproof box 101 and slides outward. The pull rod 403 pulls the scraper 401 to slide on the filter plate 301, thereby pushing the iron filings towards the extrusion plate 404. The scraper 401 and the extrusion plate 404 compress the iron filings, thereby squeezing out the coolant from the iron filings and reducing the volume of the iron filings for easier transportation.

[0047] When the scraper 401 contacts the extrusion plate 404, the cutter 402 fixed on the scraper 401 is inserted into the through hole 405 on the extrusion plate 404, thereby cutting off the excess iron filings and trimming the shape of the iron filings cake for easy transportation.

[0048] like Figure 9 and Figure 10 As shown:

[0049] Two sleeves 409 are fixedly connected to two extrusion plates 404 respectively, two ejector pins 408 are slidably connected to the two sleeves 409 respectively, and both ejector pins 408 are fixedly connected to the soundproof box 101. Two adjusting wheels 407 are threadedly connected to the two ejector pins 408 respectively, and two springs 406 are fixedly connected between the two adjusting wheels 407 and the corresponding extrusion plates 404 respectively.

[0050] When the scraper 401 and the extrusion plate 404 compress the iron filings, as the scraper 401 moves continuously, when the iron filings are compressed to the set pressure, the iron filings push the extrusion plate 404 to move backward, thereby compressing the spring 406. As a result, the ejector pin 408 moves forward in the sleeve 409 and then contacts the iron filings, thereby pushing the iron filings to the surface of the extrusion plate 404 to prevent the iron filings from sticking to the extrusion plate 404.

[0051] Rotating the adjusting wheel 407 causes it to rotate on the ejector pin 408, thereby adjusting the initial length of the spring 406, which in turn changes the amount of compression of the spring 406, thus changing the pre-pressure on the iron filings. This allows for adjustment based on the length of the iron filings, resulting in the formation of the iron filings cake and further ensuring convenient transportation.

[0052] like Figure 1 and Figure 2 As shown:

[0053] Both slide rails 109 are fixed to one of the side plates 102, and the two protective doors 110 are slidably connected between the two slide rails 109.

[0054] During machine tool operation, due to operational errors or other reasons, situations such as tool breakage and workpiece detachment may occur, causing injury to the operator. Older machine tools often lack corresponding protective functions, so auxiliary equipment is used to cover the machine tool. An operating window is machined on one side plate 102 of the auxiliary equipment. By pulling two protective doors 110, when the two protective doors 110 are open, operations such as changing tools and workpieces can be performed on the machine tool. When the machine tool is running, the two protective doors 110 are closed to protect the operator. Both protective doors 110 are equipped with viewing windows to observe the processing situation at any time.

[0055] like Figure 1-10 As shown:

[0056] The soundproof box 101 is equipped with a soundproof cotton layer; when machine tools are working, they are often very noisy, which can affect the hearing health of operators. Some old machine tools are placed in teaching buildings and used as teaching aids. Therefore, it is necessary to silence the machine tools to ensure that they do not affect the operators when they are working.
