Description

Technical Field

[0001] This invention relates to the field of machine tool component technology, and in particular to a chain-type tool magazine. Background Technology

[0002] Chain-type tool magazines are tool storage devices in CNC machine tools that use a chain structure. They belong to the random tool magazine type, and the correspondence between the tool number and the tool holder number changes with tool changes. Chain-type tool magazines improve transmission accuracy through an arc-faced cam roller structure, making them the mainstream solution for large-capacity tool configurations.

[0003] Chain-type tool magazines have the advantage of large tool capacity. To increase tool capacity, it is necessary to increase the number of chain links and expand the diameter of the chain links, or to expand the capacity by folding and rewinding. Therefore, the length of the chain of a chain-type tool magazine is positively correlated with the tool capacity. However, for chain-type tool magazines, the chain is both a load-bearing system and a transmission system. The poor mechanical rigidity of the chain and the large transmission gap result in poor positioning accuracy of the tool magazine, which means that chain-type tool magazines cannot simultaneously achieve both capacity expansion and positioning stability.

[0004] In view of this, the present invention provides a chain-type tool magazine to solve the technical problems existing in the prior art. Summary of the Invention

Then, the push-pull cylinder drives the corresponding tool chain drive mechanism and tool chain mechanism to rotate horizontally by 90° around the connecting plate, pushing the tool to below the machine head for easy tool handling. After tool replacement, the tool chain drive mechanism moves the tool chain mechanism to the tool head cleaning mechanism to clean the replaced tool head, preventing contamination and corrosion from cutting fluid, chips, etc., and improving tool storage and service life.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] Reference Figures 1-12A chain-type tool magazine includes a tool magazine mounting base 1, a tool magazine support frame 2, a tool chain drive mechanism 4, and a tool magazine housing 11. The tool magazine mounting base 1 is mounted on a machine tool. The tool magazine support frame 2 and the tool magazine housing 11 are both fixedly mounted on the top of the tool magazine mounting base 1. The side of the tool magazine support frame 2 is provided with multi-layer connecting plates 3. The surface of the tool magazine housing 11 is provided with multiple inspection windows and observation windows. Multiple tool chain drive mechanisms 4 are rotatably mounted in the gaps between the multi-layer connecting plates 3. Tool chain mechanisms 5 are sleeved on the outside of the tool chain drive mechanisms 4. A bracket 7 is fixedly mounted on the bottom of the tool chain drive mechanism 4, and a push-pull cylinder 8 is hinged between the end of the bracket 7 and the side of the tool magazine housing 11. By vertically stacking the tool chain drive mechanisms 4 and the tool chain mechanisms 5, the capacity of the tool magazine is increased. At the same time, the number of links in a single layer of tool chain mechanism 5 is reduced, and the stability of the transmission and positioning of the tool chain drive mechanisms 4 and the tool chain mechanisms 5 is improved. The side of the tool magazine housing 11 is also equipped with multi-layer connecting plates 3. The auxiliary support mechanism 9 is supported and cooperates with the bracket 7. The other end of the bracket 7 is fixedly installed with the tool chain positioning mechanism 6. When the tool is picked up, the tool chain drive mechanism 4 drives the tool chain mechanism 5 to move and move the tool to the tool chain positioning mechanism 6 for positioning and locking. At the same time, the auxiliary support mechanism 9 moves downward and disengages from the bracket 7. Then, the push-pull cylinder 8 pushes the corresponding tool chain drive mechanism 4 and tool chain mechanism 5 to rotate horizontally by 90° around the connecting plate 3, pushing the tool to the bottom of the machine head, which facilitates the picking and putting of the tool. The top of the tool magazine mounting base 1 is also equipped with a tool head cleaning mechanism 10, and the side of the tool magazine housing 11 is provided with multiple rectangular grooves that cooperate with the tool head cleaning mechanism 10. After the tool is replaced, the tool chain drive mechanism 4 drives the tool chain mechanism 5 to move the tool to the tool head cleaning mechanism 10 to clean the tool head of the replaced tool, so as to avoid the cutting fluid, chips and other contaminants on the tool head from causing pollution and corrosion, and improve the storage and service life of the tool.

[0021] The chain drive mechanism 4 includes a lower mounting plate 41 and an upper mounting plate 42 rotatably mounted between connecting plates 3. A driven sprocket 48 is rotatably mounted between the lower mounting plate 41 and the upper mounting plate 42. A tensioning assembly is provided between the lower mounting plate 41 and the upper mounting plate 42. A drive sprocket 46 is rotatably mounted on the tensioning assembly. The chain mechanism 5 is sleeved on the outside of the drive sprocket 46 and the driven sprocket 48. A servo motor 47 that drives the drive sprocket 46 to rotate is fixedly mounted at the bottom of the tensioning assembly. The tensioning assembly includes a guide groove 43 provided on the lower mounting plate 41 and the upper mounting plate 42, and a guide groove 43 mounted on the lower mounting plate 41 and the upper mounting plate 42.

The drive sprocket 46 and servo motor 47 are both mounted on the tensioning bracket 44, and the output end of the tensioning cylinder 45 is fixedly mounted on the tensioning bracket 44. A tension sensor for monitoring the tension status of the tool chain mechanism 5 is also installed between the lower mounting plate 41 and the upper mounting plate 42. The tensioning cylinder 45 is controlled to push the tensioning bracket 44 to move through the feedback data signal of the tension sensor, so as to keep the tool chain mechanism 5 in a stable tension state. The tool is moved to the corresponding position through the drive sprocket 46 and the servo motor 47 for tool picking, placing and cleaning. The blade chain mechanism 5 includes a drive chain 51 and a blade sleeve 52 fixedly installed between the drive chain 51. The outer side of the blade sleeve 52 is provided with two rectangular holes 53 distributed vertically. The outer side of the blade sleeve 52 is also provided with a blade electronic tag. The blade is inserted into the blade sleeve 52 for storage. At the same time, the side of the blade sleeve 52 is provided with rectangular holes 53 for cooperating with the blade chain positioning mechanism 6 and the blade head cleaning mechanism 10 to realize the positioning of the blade sleeve 52 and the cleaning operation of the blade head inside the blade sleeve 52. The tool chain positioning mechanism 6 includes a rectangular seat 61 mounted on the bracket 7 and a positioning cylinder 62 fixedly mounted on the rectangular seat 61. A positioning plate 63 is fixedly mounted on the outer side of the output end of the positioning cylinder 62, and two positioning parts 65 that are inserted into the rectangular hole 53 are fixedly mounted on the upper side of the positioning plate 63. A reader for identifying the electronic tag of the tool is installed between the positioning parts 65. Multiple limiting slide rods 64 are provided on the lower side of the positioning plate 63, and the limiting slide rods 64 are slidably engaged with the rectangular seat 61. The tool chain positioning mechanism 6 is located on the outside of the tool chain mechanism 5. When the tool chain mechanism 5 moves, the reader reads the information of the electronic tag of the tool on the tool sleeve 52. After the tool sleeve 52 stops, the positioning parts 65 are inserted into the rectangular hole 53 of the tool sleeve 52 to perform effective positioning operation on the tool sleeve 52, so as to avoid misalignment during the picking, placing and moving of the tool. The auxiliary support mechanism 9 includes an L-shaped support plate 91 fixedly installed on the tool magazine housing 11. An inclined groove is provided on the horizontal surface of the L-shaped support plate 91, and a movable support plate 92 is slidably connected above the inclined groove. An inclined support cylinder 93 is rotatably installed at both ends of the movable support plate 92, and the cylinder body of the inclined support cylinder 93 is installed on the L-shaped support plate 91. After the tool chain drive mechanism 4 and the tool chain mechanism 5 retract into the tool magazine housing 11, the inclined support cylinder 93 pushes the movable support plate 92 upward to lift and fix the tool chain drive mechanism 4, so as to avoid the vibration of the tool magazine operation from affecting the tool feeding accuracy. The tool cleaning mechanism 10 includes an absorption component, an air source component, and a cleaning component. Multiple cleaning components are installed on the tool magazine housing 11, and the absorption component and air source component are installed on the tool magazine mounting base 1. The air inlet of the cleaning component is connected to the air source component, and the air outlet of the cleaning component is connected to the absorption component. When the tool moves to the side of the cleaning component, the cleaning component moves horizontally and one end is inserted into the rectangular hole 53 of the tool sleeve 52. The tool edge in the tool sleeve 52 is blown out from bottom to top. The blown air is absorbed by the cleaning component from the bottom of the tool sleeve 52, filtering the cutting fluid and chips, and completing the cleaning and maintenance operation of the tool. The cleaning assembly includes a cleaning cylinder 108 mounted on the tool magazine housing 11, and a telescopic plate 109 is mounted on the output end of the cleaning cylinder 108. The front end of the telescopic plate 109 is provided with two blowing heads 1010 that are inserted into the rectangular hole 53. The inside of the blowing head 1010 is provided with an arc-shaped air guide groove. The inlet end of the blowing head 1010 is equipped with a pulse solenoid valve 1011 connected to the air source assembly. The bottom of the telescopic plate 109 is equipped with an absorption pipe 1012 connected to the absorption assembly. When the cleaning assembly approaches the tool sleeve 52, the blowing head 1010 is inserted into the rectangular hole 53. At the same time, the absorption pipe 1012 is inserted to the bottom of the tool sleeve 52. The blowing head 1010 blows tangential airflow into the tool sleeve 52 and uses the spiral airflow to blow to the cutting head of the tool. The polluted gas generated by blowing is absorbed and filtered by the absorption pipe 1012 to keep the tool clean during operation. The absorption assembly includes an absorption housing 101, and an exhaust fan 102 is installed at the outlet section of the absorption housing 101. A filter 103 is snapped onto the side of the absorption housing 101, and an absorption solenoid valve 104 connected to the absorption pipe 1012 is installed on the other side of the absorption housing 101. The exhaust gas generated by the cleaning assembly is drawn into the absorption housing 101 and filtered by the filter 103 to prevent waste from polluting the machine tool environment. The air source assembly includes an air tank 105 fixedly installed on the tool magazine housing 11, and a vertically distributed air distribution pipe 106 is installed at the outlet end of the air tank 105. A delivery hose 107 connected to the cleaning assembly is provided on the side of the air distribution pipe 106. The cleaning assembly provides stable and clean compressed air through the air source assembly to blow away debris on the tool surface.

[0022] In use, the vertically stacked tool chain drive mechanism 4 and tool chain mechanism 5 increase the tool magazine capacity while reducing the number of links in a single layer of tool chain mechanism 5, thus improving the stability of the transmission and positioning of the tool chain drive mechanism 4 and tool chain mechanism 5. When picking up a tool, the tool chain drive mechanism 4 drives the tool chain mechanism 5 to move the tool to the tool chain positioning mechanism 6 for positioning and locking. At the same time, the auxiliary support mechanism 9 moves downward and disengages from the bracket 7. Then, the push-pull cylinder 8 pushes the corresponding tool chain drive mechanism 4 and tool chain mechanism 5 to rotate horizontally by 90° around the connecting plate 3, pushing the tool to below the machine head for easy tool picking and putting. After tool replacement, the tool chain drive mechanism 4 drives the tool chain mechanism 5 to move the tool to the tool head cleaning mechanism 10 to clean the tool head, preventing contamination and corrosion caused by cutting fluid, chips, etc., and improving tool storage and service life.
