Technical Field

[0001] This invention relates to the field of machining center technology, specifically to a multi-spindle linkage machining center spindle box system. Background Technology

[0002] With the rapid development of industrialization, machining center equipment has also evolved. For multi-spindle linkage machining centers, the spindle box is an essential component. However, existing spindle boxes generate heat during prolonged use due to the continuous friction of multiple spindles rotating in linkage. Most rely on ventilation holes for heat dissipation, which is extremely inefficient. This method cannot utilize circulating coolant to carry away and dissipate heat from the spindle box, resulting in heat accumulating inside without cooling. This exacerbates wear and damage to internal components. Furthermore, installation of the spindle box with the machining center typically involves tightening multiple bolts with tools, hindering quick installation and reducing the efficiency of disassembly, assembly, and maintenance. Therefore, a multi-spindle linkage machining center spindle box system is proposed. Summary of the Invention

[0010] Preferably, lifting lugs are fixedly connected to all four sides of the top of the spindle housing. The lifting lugs are made of high-manganese carbon steel and are distributed in a triangular shape along the center of the top of the spindle housing.

[0011] Preferably, guide blocks are fixedly connected to all four sides of the left side of the mounting plate, and guide holes that engage with the guide blocks are opened around the inner cavity of the circular docking groove.

[0012] Preferably, the top and bottom right sides of the spindle housing are provided with first mating grooves for use with the first cooling plate, and the front and back sides of the spindle housing are provided with second mating grooves for use with the second cooling plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this invention, a cooling mechanism is provided, with a coolant tank supplying sufficient coolant and a small circulating pump providing circulating power. Through the combined transport of two main pipes and two sets of branch pipes, two sets of first cooling plates circulate and dissipate heat from the top and bottom areas of the spindle housing cavity. Then, through the combined transport of bent pipes and two sets of cross pipes, a second cooling plate circulates and dissipates heat from the sides of the spindle housing cavity. Auxiliary cooling plates further assist in cooling the spindle housing. The heat exchange holes effectively ventilate and dissipate heat from the spindle housing, achieving uniform cooling and dissipation of heat within the spindle housing. This provides effective protection for the internal components of the spindle housing. An installation mechanism is also included, with the locking mechanism between the mounting plate and mounting bracket achieving a pre-locking effect between them. Two small liquid cylinders provide the driving power, and the positioning bracket and locking rod are inserted into the corresponding positioning and locking slots for quick installation of the mounting plate and mounting bracket. This facilitates rapid disassembly and maintenance of the spindle housing, reducing user waiting time.

[0015] 2. In this invention, by setting a clamping sleeve, the main pipe and cross pipe can be firmly fixed to the spindle housing, preventing the main pipe and cross pipe from loosening or falling off when the coolant circulates in the main pipe and cross pipe. By setting lifting lugs distributed in a triangular pattern, when the spindle housing needs to be installed and disassembled, it is convenient for users to use lifting tools to suspend the spindle housing, thereby improving the convenience of installation and disassembly of the spindle housing.

[0016] 3. In this invention, by setting a snap-fit ​​between the guide block and the guide hole, it is convenient for the user to guide the installation of the mounting plate and the mounting bracket, preventing misalignment during installation and shortening the installation time. By setting a first mating groove and a second mating groove, the first cooling plate and the second cooling plate can directly contact the heat inside the spindle housing, enhancing the heat dissipation effect of the first cooling plate and the second cooling plate on the heat inside the spindle housing.

[0017] This invention improves the protection of internal components of the spindle housing by providing a cooling mechanism that evenly dissipates heat. Furthermore, the installation mechanism allows for quick assembly and disassembly of the mounting plate and mounting bracket, facilitating rapid disassembly and maintenance and reducing user waiting time.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] Please see Figure 1-6This invention provides a technical solution: a multi-spindle linkage machining center spindle box system, including a spindle box body 1. Cooling mechanisms 2 are arranged around the spindle box body 1. Sufficient coolant is provided by a coolant tank 21, and a small circulating pump 22 provides the circulating power. Through the coordination of two main pipes 23 and two sets of branch pipes 24, two sets of first cooling plates 25 circulate and dissipate heat from the top and bottom areas of the spindle box body 1's inner cavity. Then, through the coordination of bent pipes 26 and two sets of cross pipes 27, second cooling plates 28 circulate and dissipate heat from the sides of the inner cavity of the spindle box body 1. Auxiliary cooling plates 29 provide auxiliary cooling and heat dissipation for the internal heat of the spindle box body 1. Heat exchange holes 210 effectively ventilate and dissipate heat from the internal heat of the spindle box body 1, achieving uniform cooling and heat dissipation of the internal heat of the spindle box body 1 and providing effective protection for the internal components. Spindle tools 3 are rotatably connected to the four sides of the right side of the spindle box body 1. A mounting plate 4 is fixedly connected to the left side of the body 1. A mounting bracket 5 is provided on the left side of the mounting plate 4. A circular docking groove 6 is provided at the center of the right side of the mounting bracket 5 to cooperate with the mounting plate 4. The depth of the circular docking groove 6 is greater than the thickness of the mounting plate 4, which can conceal the mounting plate 4 and prevent it from being exposed after installation. Vertical through grooves 7 are provided on both the front and rear sides of the mounting bracket 5. A bracket 8 is fixedly connected to the center of both the front and rear sides of the mounting bracket 5. The bracket 8 is located outside the through groove 7. Mounting mechanisms 9 are provided on both sides of the mounting bracket 5 and the mounting plate 4 facing each other. By setting up mounting mechanisms 9, the pre-locking effect between the mounting plate 4 and the mounting bracket 5 is achieved through the locking cooperation between the card seat 91 and the card slot 92. The driving source is provided by two small liquid cylinders 93. The positioning bracket 94 and the locking rod 95 are inserted into the positioning groove 96 and the locking groove 97 respectively, so that the mounting plate 4 and the mounting bracket 5 can be quickly installed. This facilitates the user to quickly disassemble and repair the spindle housing 1 and reduce the user's waiting time.

[0028] Example 2

[0029] Please see Figure 1-6This invention provides a technical solution: a multi-spindle linkage machining center spindle box system, including a spindle box body 1. Lifting lugs 10 are fixedly connected to all four sides of the top of the spindle box body 1. When the spindle box body 1 needs to be installed and disassembled, it facilitates the user's use of lifting tools to suspend the spindle box body 1, improving the ease of installation and disassembly. The lifting lugs 10 are made of high-manganese carbon steel, improving the material strength and tensile strength of the lifting lugs 10, preventing breakage under stress. The lifting lugs 10 are distributed in a triangular pattern along the center of the top of the spindle box body 1, ensuring a reasonable distribution and stable lifting operation of the spindle box body 1. Cooling mechanisms 2 are provided around all four sides of the spindle box body 1, and the cooling mechanism 2 includes a coolant tank 21. The top of the coolant tank 21 is connected to a filling pipe, and the bottom of the coolant tank 21 is connected to a drain pipe. Both the filling and drain pipes are threaded with sealing caps to prevent coolant leakage. The coolant tank 21 is fixed to the left side of the top of the spindle housing 1, and its outlet is connected to a small circulation pump 22. The small circulation pump 22 has main pipes 23 at its top and bottom, away from the coolant tank 21. Both ends of the main pipe 23 away from the small circulation pump 22 are connected to branch pipes 24, and the other end of each branch pipe 24 is connected to a first cooling plate 25 that works with the spindle housing 1. The first cooling plate 25 is shaped like a flat-topped cone, expanding the connection between the first cooling plate 25 and the spindle housing 1. The heat dissipation area between the housing 1 is achieved by connecting both ends of the main pipe 23 to bends 26, with the inner ends of the bends 26 connected to cross tubes 27. Both sides of the inner walls of the main pipe 23 and cross tubes 27 are fixedly connected to clamps that are fixedly fitted to the spindle housing 1, ensuring a secure fixation between the main pipe 23 and cross tubes 27 and the spindle housing 1. This prevents the main pipe 23 and cross tubes 27 from loosening or falling off during coolant circulation. Both ends of the cross tube 27 at its center are connected to a second cooling plate 28 that works with the spindle housing 1. The second cooling plate 28 is elliptical in shape, increasing the heat dissipation area between the first cooling plate 25 and the spindle housing 1, while also allowing for greater coolant flow, thus effectively dissipating heat from the side areas of the spindle housing 1. For effective heat dissipation, both the first cooling plate 25 and the second cooling plate 28 have hollow chamber structures inside, allowing for fluid storage of coolant and improving the heat transfer efficiency inside the spindle housing 1. First mating grooves 13, for use with the first cooling plate 25, are sequentially formed on the right sides of the top and bottom of the spindle housing 1 from front to back. Second mating grooves 14, for use with the second cooling plate 28, are formed on both sides of the front and back of the spindle housing 1, allowing the first and second cooling plates 25 and 28 to directly contact the heat inside the spindle housing 1, enhancing their heat dissipation effect. Auxiliary cooling plates 29 are provided at opposite ends of both the first and second cooling plates 25 and 28.The spindle housing 1 has exchange holes 210 on all four sides. A cooling mechanism 2 provides sufficient coolant from a coolant tank 21 and a small circulating pump 22 for circulation. Through the combined action of two main pipes 23 and two sets of branch pipes 24, two sets of first cooling plates 25 circulate and dissipate heat from the top and bottom areas of the spindle housing 1's interior. Then, through the combined action of bent pipes 26 and two sets of cross pipes 27, a second cooling plate 28 circulates and dissipates heat from the sides of the spindle housing 1's interior. Auxiliary cooling plates 29 further assist in cooling the interior of the spindle housing 1. The exchange holes 210 effectively exchange and dissipate heat from the interior of the spindle housing 1, achieving uniform cooling of the interior. The heat dissipation effect effectively protects the internal components of the spindle housing 1. Spindle cutters 3 are rotatably connected to the four sides of the right side of the spindle housing 1. A mounting plate 4 is fixedly connected to the left side of the spindle housing 1. Guide blocks 11 are fixedly connected to the four sides of the left side of the mounting plate 4. A mounting bracket 5 is provided on the left side of the mounting plate 4. A circular mating groove 6, which mates with the mounting plate 4, is opened at the center of the right side of the mounting bracket 5. Guide holes 12, which engage with the guide blocks 11, are opened around the perimeter of the circular mating groove 6, facilitating guidance during the installation of the mounting plate 4 and mounting bracket 5, preventing misalignment, and shortening the installation time. The depth of the circular mating groove 6 is greater than the thickness of the mounting plate 4, allowing for better control of the mounting plate. 4. To conceal the installation and prevent the mounting plate 4 from being exposed after installation, the mounting frame 5 has vertically opened through slots 7 on both the front and rear sides. A bracket 8 is fixedly connected to the center of both the front and rear sides of the mounting frame 5, located outside the through slots 7. Mounting mechanisms 9 are provided on the opposite sides of the mounting frame 5 and the mounting plate 4. Each mounting mechanism 9 includes a retainer 91, which is fixed at the center of the circular mating groove 6. A slot 92 is opened at the center of the left side of the mounting plate 4 to engage with the retainer 91. The retainer 91 and slot 92 are shaped like equilateral triangles to improve the tightness of the engagement between them, based on the principle of triangle stability. A small liquid cylinder 93 is fixedly connected to the outside of the bracket 8, and the piston rod of the small liquid cylinder 93 is fixedly connected to... A positioning frame 94 is connected to the through slot 7. Locking rods 95 are fixedly connected to both sides of the positioning frame 94. Positioning slots 96 and locking slots 97 are respectively opened on both sides of the mounting plate 4 to engage with the positioning frame 94 and locking rods 95. The positioning frame 94 and positioning slots 96 adopt a "T"-shaped structure to improve the engagement and tightness between them, and also to limit the movement of the positioning frame 94 and positioning slots 96 after engagement. By setting up the installation mechanism 9, the engagement between the card seat 91 and the card slot 92 achieves a pre-engagement effect between the mounting plate 4 and the mounting frame 5. Two small liquid cylinders 93 provide the driving force, and the positioning frame 94 and locking rods 95 are inserted into the corresponding positioning slots 96 and locking slots 97.This allows for quick installation between the mounting plate 4 and the mounting bracket 5, facilitating rapid disassembly and maintenance of the spindle housing 1 and reducing user waiting time.

[0030] Working principle: When the user installs the spindle housing 1, the user uses a lifting tool to hook the lifting lug 10 and inserts the mounting plate 4 on the spindle housing 1 into the circular docking groove 6, so that the guide block 11 is inserted into the guide hole 12 and the card seat 91 is inserted into the card slot 92. Then, the two small liquid cylinders 93 drive the positioning frame 94 to push inward in the through groove 7. The positioning frame 94 is inserted into the positioning groove 96. At the same time, the positioning frame 94 also drives the locking rod 95 to be inserted into the locking groove 97, thus fixing the mounting plate 4 and the mounting frame 5 and completing the installation of the spindle housing 1.

[0031] When the spindle housing 1 generates high temperature heat during long-term use, the small circulating pump 22 supplies the coolant in the coolant tank 21 into the main pipe 23. Then, the main pipe 23 flows into the first cooling plate 25 through the branch pipe 24. At the same time, the coolant in the main pipe 23 also flows into the cross pipe 27 through the bend pipe 26, and then into the second cooling plate 28. Since the first cooling plate 25 and the second cooling plate 28 are both hollow chamber structures, the coolant in the chambers of the first cooling plate 25 and the second cooling plate 28 carries away and dissipates the heat inside the spindle housing 1 through the cooperation of the first mating groove 13 and the second mating groove 14. The auxiliary cooling plate 29 assists in cooling and dissipating the heat. The heat inside the spindle housing 1 is then discharged through the exchange hole 210.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
