Description

Technical Field

[0001] This utility model belongs to the field of machine tool tool magazine technology, and particularly relates to a linkage tool magazine for maintaining cutting tools. Background Technology

[0002] Tool magazines are mainly installed in machining equipment such as lathes and milling machines. They are devices that provide tool storage and tool changing services required in automated machining processes.

[0003] Traditional tool magazines mainly consist of a magazine body, a tool holder, and a drive unit. The tool holder is slidably connected to the magazine body and is used to hold rows of tools. The drive unit is mounted on the magazine body and is used to drive the tool holder in and out. The magazine body also has a hinged door for sealing and storing the tools inside. When changing or taking out tools, first open the tool magazine door, and then use the drive unit to push the carrier out of the magazine body. It is simple and convenient to use.

[0004] However, in actual use, it has been found that existing tool magazines only have the functions of storing and changing tools, but cannot maintain and service the tools, which makes it difficult to guarantee the service life of the stored tools. Therefore, it is necessary to design a new tool magazine to solve this problem. Utility Model Content

[0005] Technical problems to be solved

[0006] This invention provides a linkage-type tool magazine for maintaining cutting tools, which can promptly maintain and care for the tools entering the magazine, thus extending the service life of the tools.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A linkage-type tool magazine for maintaining cutting tools includes a magazine body, a tool holder, a drive unit, and a spraying unit. The magazine body has an outwardly opening receiving cavity, and a door hinged to the magazine body for opening and closing the receiving cavity. The tool holder is movably installed within the receiving cavity, and the tool holder has a stop block and a fixing position for placing cutting tools. The drive unit is installed on the magazine body and drivenly connected to the tool holder to drive the tool holder in and out of the receiving cavity through the receiving cavity opening. The spraying unit is installed within the receiving cavity, with the spraying end of the spraying unit corresponding to the cutting tool, and the actuation end of the spraying unit corresponding to the stop block. When the drive unit drives the tool holder fully into the receiving cavity, the stop block abuts against and triggers the actuation end of the spraying unit, causing the spraying end of the spraying unit to spray cleaning fluid onto the cutting tool.

[0010] Preferably, the tool holder is further equipped with a guide block, and a guide rail extending toward the opening of the cavity is installed on the inner wall of the receiving cavity. The guide block is slidably mounted on the guide rail so that the tool holder can be movably mounted in the receiving cavity and can enter and exit the receiving cavity.

[0011] Preferably, the driving unit is a cylinder, and the telescopic shaft of the cylinder is fixed to the tool holder to drive the tool holder to move along the length direction of the guide rail.

[0012] Preferably, the spraying unit includes a mechanical pump and a nozzle, with the nozzle serving as the spraying end of the spraying unit. The mechanical pump includes a pump base, a piston, a spring, and a pressure block. The pump base has an air chamber connecting an external liquid source and the nozzle. The piston is movably mounted in the air chamber. The spring is disposed in the air chamber and abuts against the inner wall of the air chamber and the piston. The pressure block is movably disposed in the air chamber and abuts against the piston. The pressure block also has a pressure rod penetrating the air chamber to the outside, which serves as the starting end of the spraying unit. When the pressure block contacts and squeezes the pressure rod as the tool holder moves, the pressure rod drives the piston to move downward along the air chamber through the pressure block, pumping the cleaning fluid from the external liquid source into the air chamber and spraying it onto the tool through the nozzle. During this process, the spring deforms and stores energy. When the pressure block moves away from the pressure rod as the tool holder moves, the spring releases energy and returns to its original position, driving the piston and the pressure block to reset.

[0013] Preferably, the spraying part further includes a liquid guide box, which is installed below the knife holder, and the liquid guide box has a diversion channel inside. The diversion channel is connected to a liquid inlet and multiple liquid outlets. The liquid inlet is connected to the air chamber through a first flexible tube, and multiple nozzles are provided and installed at multiple liquid outlets.

[0014] Preferably, the spraying unit further includes a liquid storage tank, which is installed on the tank body and used to load cleaning fluid for use as an external liquid source, and the liquid storage tank is connected to the air chamber through a second hose.

[0015] Preferably, both the first hose and the second hose are equipped with a one-way valve to prevent the cleaning fluid in the liquid guide box from flowing back into the air chamber and / or the liquid storage tank.

[0016] Preferably, the mechanical pump is replaced with an electric pump, the electric pump having an inlet connecting the liquid storage tank and the liquid guide box, and the electric pump having a switch button for starting the spray section; wherein, when the blade holder drives the stop block to contact and squeeze the switch button, the electric pump starts to pump the cleaning fluid from the external liquid source to the nozzle to spray the blade; the electric pump will automatically shut down after working for a certain period of time, or the blade holder will drive the stop block to disengage from the switch button, thereby passively shutting down the electric pump.

[0017] Preferably, the bottom of the receiving cavity is provided with an opening to the outside for discharging the cleaning fluid inside the receiving cavity.

[0018] Preferably, it further includes a linkage unit, which is installed in the receiving cavity and is connected to the tool holder and the magazine door drive; wherein, during the process of the drive unit driving the tool holder into the receiving cavity, the tool holder synchronously drives the magazine door to close the opening of the receiving cavity through the linkage unit, and during the process of the drive unit driving the tool holder to move out of the receiving cavity, the tool holder synchronously drives the magazine door to open the opening of the receiving cavity through the linkage unit.

[0019] Preferably, the linkage includes a first link, a second link, and a third link. The middle part of the second link is rotatably mounted on the side wall of the receiving cavity, and the two ends of the second link are rotatably connected to the tail ends of the first link and the tail ends of the second link, respectively. The head end of the first link is rotatably mounted on the knife holder, and the head end of the third link is rotatably mounted on the inner wall of the door.

[0020] During the process of the drive unit driving the tool holder into the receiving cavity, the first connecting rod drives the third connecting rod to swing upward through the second connecting rod, thereby causing the door to close the opening of the receiving cavity; during the process of the drive unit driving the tool holder out of the receiving cavity, the first connecting rod drives the third connecting rod to swing downward through the second connecting rod, thereby causing the door to open the opening of the receiving cavity.

[0021] (III) Beneficial Effects

[0022] This utility model provides a linkage-type tool magazine for tool maintenance.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0042] See appendix Figure 1 -Appendix Figure 10 A linkage-type tool magazine for maintaining cutting tools includes a magazine body 1, a tool holder 2, a drive unit 3, and a spraying unit 4. The magazine body 1 has an outwardly opening receiving cavity 10, and a magazine door 11 for opening and closing the receiving cavity 10 is hinged to the magazine body 1. The tool holder 2 is movably installed in the receiving cavity 10, and the tool holder 2 has a stop block 21 and a fixing position 20 for placing a cutting tool P. The drive unit 3 is installed on the magazine body 1 and drivenly connected to the tool holder 2 to drive the tool holder 2 to enter and exit the receiving cavity 10 through the opening of the receiving cavity 10. The spraying unit 4 is installed in the receiving cavity 10, and the spraying end of the spraying unit 4 corresponds to the cutting tool P, while the starting end of the spraying unit 4 corresponds to the stop block 21. When the drive unit 3 drives the tool holder 2 to move, the stop block 21 can move with the tool holder 2 to abut or disengage from the starting end of the spraying unit 4.

[0043] Specifically, when the drive unit 3 drives the tool holder 2 to move out of the receiving cavity 10, it facilitates the machine tool (not shown in the figure) to pick up and put the tool P on the fixed position 20. At the same time, since the stop block 21 disengages from the starting end of the spraying unit 4, the spraying unit 4 remains closed. When the drive unit 3 drives the tool holder 2 to complete entering the receiving cavity 10, the storage door 11 is closed to store the tool P in the receiving cavity 10. At the same time, since the stop block 21 abuts against the starting end of the spraying unit 4, the spraying end of the spraying unit 4 sprays cleaning fluid onto the tool P.

[0044] It should be noted that the cleaning fluid can be either water or blade oil. Water can clean the blade P and remove debris to maintain it, while blade oil, in addition to removing debris, can also prevent corrosion and rust, further improving the maintenance effect. Besides the examples mentioned above, other liquids can also be used as the cleaning fluid. Due to the variety of actual types, this invention does not impose any restrictions on this. On the other hand, regarding whether the spraying part of the spraying part 4 sprays the cleaning fluid onto the blade P in a single application or continuously when the abutment block 21 triggers the start end, this can be determined according to the actual structure and usage requirements, and this invention does not impose any restrictions on this.

[0045] In summary, this utility model designs a spraying section 4 to spray cleaning fluid onto the tool P stored in the receiving cavity 10, thereby maintaining the tool P and effectively extending its service life. By designing a pressure block 414 on the tool holder 2 corresponding to the starting end of the spraying section 4, the drive unit 3 can control the tool P to enter and exit the receiving cavity 10 and can also control the starting timing of the spraying section 4 in a timely manner, enriching the linkage function of the drive unit 3 and ensuring the compactness of the overall structure of the tool magazine.

[0046] See appendix Figure 3 -Appendix Figure 8 and attached Figure 15 -Appendix Figure 16 The tool holder 2 is also equipped with a guide block 22, and a guide rail 12 extending toward the opening of the cavity 10 is installed on the inner wall of the cavity 10. The guide block 22 is slidably mounted on the guide rail 12 so that the tool holder 2 can be movably mounted in the cavity 10. When the drive unit 3 drives the guide block 22 to move along the length of the guide rail 12, the tool holder 2 can enter and exit the cavity 10.

[0047] It should be noted that, in addition to the sliding structure of guide block 22 and guide rail 12, the tool holder 2 can also be movably installed on the inner wall of the receiving cavity 10 using other structures. Since there are many types of related structures, this utility model does not limit them.

[0048] See appendix Figure 3 -Appendix Figure 8 and attached Figure 15 The drive unit 3 uses a cylinder 30, and the telescopic shaft of the cylinder 30 is fixed to the tool holder 2. By controlling the extension and retraction of the telescopic shaft of the cylinder 30, the tool holder 2 can be driven to move along the length direction of the guide rail 12.

[0049] It should be noted that, in addition to using a cylinder 30, the drive unit 3 can also use a screw motor or other structures with a travel stroke. Since there are many types of related structures, this utility model does not impose any restrictions on them.

[0050] See appendix Figure 9 -Appendix Figure 14The liquid spraying section 4 includes a mechanical pump 41 and a nozzle 40. The nozzle 40 is used as the spraying end of the liquid spraying section 4. The mechanical pump 41 includes a pump base 411, a piston 412, a spring 413, and a pressure block 414. The pump base 411 has an air chamber 4110 that connects to an external liquid source and the nozzle 40. The piston 412 is movably installed in the air chamber 4110. The pressure block 414 is movably disposed in the air chamber 4110 and abuts against the piston 412. The pressure block 414 is also provided with a pressure rod 4140 that penetrates the air chamber 4110 to the outside. The pressure rod 4140 is used as the starting end of the liquid spraying section 4. The spring 413 is disposed in the air chamber 4110 and abuts against the inner wall of the air chamber 4110 and the piston 412. The spring 413 can store or release energy when it is squeezed or disengaged from the pressure rod 4140 by the abutment 21.

[0051] Specifically, when the abutment 21 moves with the tool holder 2 and contacts the pressing rod 4140 to move downward, the pressing rod 4140 drives the piston 412 to move downward along the air chamber 4110 through the pressing block 414, so as to pump the cleaning fluid from the external liquid source into the air chamber 4110 and spray it onto the tool P through the nozzle 40. During this process, the spring 413 deforms and stores energy. When the abutment 21 moves with the tool holder 2 and disengages from the pressing rod 4140, the spring 413 releases energy and restores itself, driving the piston 412 and the pressing block 414 to reset, so that the abutment 21 can press the pressing rod 4140 again.

[0052] Based on the above, it can be seen that after using the mechanical pump 41, the block 21 presses the pressure rod 4140 intentionally, and the nozzle 40 sprays cleaning fluid onto the tool P in a single spray. This design can effectively save cleaning fluid.

[0053] See appendix Figure 9 -Appendix Figure 12 The spraying section 4 also includes a liquid guide box 42, which is installed below the blade holder 2. The liquid guide box 42 has a diversion channel 420 inside, which connects to an inlet 421 and multiple outlets 422. The inlet 421 is connected to the air chamber 4110 via a first flexible hose 4211. Multiple nozzles 40 are provided and installed at multiple outlets 422. This structural design allows for centralized reception and diversion of the cleaning liquid, avoiding the need for multiple first flexible hoses 4211 to connect to multiple nozzles 40, thus ensuring the cleanliness of the interior of the receiving cavity 10.

[0054] See appendix Figure 6 -Appendix Figure 10 The spraying unit 4 also includes a liquid storage tank 43, which is installed on the tank body 1 and used to load cleaning fluid for use as an external liquid source. The liquid storage tank 43 is connected to the air chamber 4110 through a second hose 431.

[0055] Specifically, when the stop block 21 presses the pressure rod 4140 to drive the piston 412 downward, the cleaning fluid in the storage tank 43 is pumped into the air chamber 4110 through the second hose 431 and into the liquid guide box 42 through the first hose 4211, and finally sprayed onto the tool P through multiple nozzles 40; the design of the storage tank 43 allows the tool magazine to have its own cleaning fluid, improving the convenience of use.

[0056] See appendix Figure 10 One-way valves 4d are installed on both the first hose 4211 and the second hose 431. This design can prevent the cleaning fluid in the liquid guide box 42 from flowing back into the air chamber 4110 and / or the liquid storage tank 43, further improving the operational stability of the mechanical pump 41.

[0057] Furthermore, in another embodiment, the mechanical pump 41 can be replaced with an electric pump (not shown in the figure). The electric pump connects the inlet 421 of the liquid storage tank 43 and the liquid guide box 42, and the electric pump is equipped with a switch button (not shown in the figure) used as the start end of the spraying part 4. When the knife holder 2 drives the stop block 21 to contact the squeeze switch button, the electric pump starts to pump the cleaning liquid in the external liquid source to the nozzle 40 to spray the knife P. The electric pump will automatically shut off after running for a certain period of time, or the electric pump will be passively shut off after the knife holder 2 drives the stop block 21 to disengage from the switch button.

[0058] The electric pump is an existing product, so its internal structure will not be described in detail in this utility model. The technology of controlling the start and stop of the electric pump by a switch button is also quite conventional, so its specific circuit structure will not be described in detail in this embodiment.

[0059] Based on existing technology, it is known that by pre-setting a corresponding control program, at least two control methods can be achieved for a single press of the switch button: one is to control the electric pump to run for a specific period of time and then automatically shut it off, and the other is to control the electric pump to run continuously. If the first control method is adopted, it can be ensured that after the switch button is pressed on block 21, the nozzle 40 can only spray cleaning fluid onto the tool P once or multiple times at a specific time, avoiding excessive consumption of cleaning fluid. If the second control method is adopted, after the switch button is pressed on block 21, the nozzle 40 will continuously spray cleaning fluid onto the tool P once or multiple times, so that the cavity 10 can be continuously maintained. In order to save energy, the first control method is generally adopted, while if the cleaning fluid in the cavity 10 can be recycled, the second control method can be adopted.

[0060] It should be noted that replacing the mechanical pump 41 with an electric pump requires an external power supply to power the electric pump. Therefore, the mechanical pump 41 is preferred in this utility model. In addition, other pump body structures can be used besides electric pumps and mechanical pumps 41. Since there are many types of pump body structures, this utility model does not limit them.

[0061] See appendix Figure 1 and attached Figure 9 The bottom of the receiving cavity 10 is also provided with a port 100 for connecting to the outside. This design can be used to discharge the cleaning fluid in the receiving cavity 10 and prevent the cleaning fluid from accumulating in the receiving cavity 10.

[0062] See appendix Figure 8 Appendix Figure 15 and attached Figure 16 The present invention also includes a linkage part 5, which is installed in the receiving cavity 10 and is drivenly connected to the tool holder 2 and the door 11, so that the door 11 can move with the tool holder 2 to open or close the opening of the receiving cavity 10.

[0063] Specifically, during the process of the drive unit 3 driving the tool holder 2 into the receiving cavity 10, the tool holder 2 synchronously drives the magazine door 11 to close the opening of the receiving cavity 10 through the linkage unit 5, so that the magazine door 11 closes in time and prevents the cleaning fluid from spraying out of the opening of the receiving cavity 10 and causing stains on the machine tool; during the process of the drive unit 3 driving the tool holder 2 out of the receiving cavity 10, the tool holder 2 synchronously drives the magazine door 11 to open the opening of the receiving cavity 10 through the linkage unit 5, so as to prevent the magazine door 11 from obstructing the exposure of the tool P; this structural design allows the drive unit 3 to control the tool P entering and exiting the receiving cavity 10, control the start timing of the spraying unit 4, and control the opening and closing timing of the magazine door 11 in time, further enriching the linkage function of the drive unit 3 and ensuring the compactness of the overall structure of the tool magazine.

[0064] See appendix Figure 8 Appendix Figure 15 and attached Figure 16 The structure of the linkage 5 is varied, and no limitation is made in this utility model. For ease of understanding, the linkage 5 in this embodiment includes a first connecting rod 51, a second connecting rod 52, and a third connecting rod 53. The middle part of the second connecting rod 52 is rotatably mounted on the side wall of the receiving cavity 10, and the two ends of the second connecting rod 52 are rotatably connected to the tail ends of the first connecting rod 51 and the tail ends of the second connecting rod 52, respectively. The head end of the first connecting rod 51 is rotatably mounted on the tool holder 2, and the head end of the third connecting rod 53 is rotatably mounted on the inner wall of the door 11. During the process of the driving part 3 driving the tool holder 2 into the receiving cavity 10, the first connecting rod 51 drives the third connecting rod 53 to swing upward through the second connecting rod 52, so as to drive the door 11 to close the opening of the receiving cavity 10. During the process of the driving part 3 driving the tool holder 2 out of the receiving cavity 10, the first connecting rod 51 drives the third connecting rod 53 to swing downward through the second connecting rod 52, so as to drive the door 11 to open the opening of the receiving cavity 10.

[0065] It should also be noted that, although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application.
