Description

Technical Field

[0001] This utility model relates to the field of machine tool headstock technology, and in particular to a linearly moving headstock. Background Technology

[0002] The machine head magazine is an important mechanism for storing and managing spindle heads. When it is necessary to replace the spindle head, the gripping mechanism of the machine head magazine will grab the required spindle head, the machine ram will extend and dock with the spindle head, and the replacement of the spindle head will be completed.

[0003] In existing technologies, headstocks are all fixed headstocks located within the machine tool machining area. This type of headstock has two disadvantages: First, it significantly occupies space in the machine tool machining area, increasing the area required for machine tool installation; second, the spindle head in the headstock is easily contaminated by cutting chips and cutting fluid carried on the spindle head on the ram during head changes, which reduces the installation accuracy of the spindle head and makes it impossible to guarantee machining quality. Utility Model Content

[0017] Furthermore, the base structure also includes a foot adjustment device disposed on the base plate.

[0018] Furthermore, the driving structure is a linear driving structure.

[0019] The beneficial effects of this utility model are:

[0020] This utility model discloses a linear moving head magazine. When a head change is needed, the drive structure directly moves the head magazine to the machine tool processing area via a drive trolley structure to achieve the head change. This does not occupy the layout space of the processing area. Moreover, the head magazine is located outside the processing area during machine tool processing, which can prevent cutting chips generated during processing from contaminating the head to be replaced.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0041] like Figure 1-7 The image shown is a linearly moving head unit provided in this embodiment, including a base structure 1, a moving vehicle structure 2, a drive structure 3, and a purging structure 4;

[0042] The mobile carriage structure 2 is provided with a plurality of spindle heads 5. The drive structure 3 can drive the mobile carriage structure 2 to move towards the processing area 6 on the base structure 1 and enter the processing area of ​​the machine tool, or to move away from the processing area 6 and move out of the processing area.

[0043] The purging structure 4 is located on the side of the mobile vehicle structure 2 facing the processing area 6.

[0044] This utility model discloses a linear moving spindle head magazine. When a head change is needed, the drive structure directly moves the spindle head magazine to the machine tool processing area via a drive trolley structure to achieve the head change. This does not occupy the layout space of the processing area. Moreover, the spindle head magazine is located outside the processing area during machine tool processing, which can prevent cutting chips generated during processing from contaminating the spindle head to be replaced. At the same time, the set-in blowing structure can blow away the cutting chips and cutting fluid on the spindle head in the processing area before the spindle head magazine moves into the machine tool processing area for head change, preventing cutting chips from falling onto the spindle head in the trolley structure during head change, and avoiding contamination of the interchangeable spindle head docking interface in the processing area. This prevents cutting chips and cutting fluid from affecting the installation position accuracy of the spindle head, ensuring processing quality, and significantly reducing the equipment failure rate caused by the accumulation of impurities, improving the stability and reliability of machine tool operation. It can also effectively avoid the problem of accuracy reduction caused by contaminants entering key components, ensuring processing quality and workpiece surface finish.

[0045] In a specific embodiment, such as Figure 3 As shown, the base structure 1 includes a base plate 11 and a movable circular rail 12;

[0046] The mobile vehicle structure 2 includes a vehicle body 21 and rollers 22 disposed at the bottom of the vehicle body 21, and a plurality of the main shaft heads 5 are disposed on the vehicle body 21;

[0047] One end of the base plate 11 is located inside the processing area 6, and the other end is located outside the processing area. The movable circular rail 12 is located on the base plate 11, and the roller 22 is installed on the movable circular rail 12. The movable circular rail 12 is set along the setting direction of the base plate 11, that is, along the direction of entering or leaving the processing area of ​​the machine tool. The roller is an arc-shaped roller, which is installed on the movable circular rail 12. Under the drive of the drive structure 3, the vehicle body can drive the spindle head (slot) into or out of the processing area of ​​the machine tool. The movable circular rail 12 and the arc-shaped roller can ensure the stability of the vehicle body movement, thereby ensuring the stability and reliability of the spindle head movement.

[0048] In a specific embodiment, such as Figure 3 As shown, a protective door 7 for installing the blowing structure 4 is provided on the side of the vehicle body 21 near the machining area 6. The protective door can prevent the spindle head outside the machining area from being contaminated by cutting chips generated during machining. The protective door is located on the side of the vehicle body facing the machining area. The protective door provides a placement position for the installation of the blowing structure 4. The blowing structure 4 is installed on the side of the protective door away from the vehicle body, which allows the blowing structure 4 to blow away the cutting chips and cutting fluid on the spindle head on the machine tool slide in the machining area before the head replacement after the vehicle body moves to the position in the machining area to replace the spindle head. This prevents the spindle head to be replaced on the vehicle body and the interface of the replacement head in the machining area from being contaminated.

[0049] In a specific embodiment, such as Figure 1 , Figure 9 As shown, the vehicle body is provided with several V-shaped support blocks 14; several V-shaped support blocks are set on the top of the vehicle body, and the main shaft head is provided with a support column. When the main shaft head is placed on the vehicle body, the support column is located in the V-shaped support block, which facilitates the support of the main shaft head and also facilitates the gripping, installation and replacement of the main shaft head when it needs to be replaced.

[0050] In a specific embodiment, such as Figure 9 As shown, the vehicle body is provided with a detection sensor assembly 15; the detection sensor assembly includes a detection sensor fixing plate 151 and a first detection sensor 152 and a second detection sensor 153 disposed on the detection sensor fixing plate. The detection sensor fixing plate 151 is disposed on the vehicle body 21, and the vehicle body 21 is provided with a plurality of spindle head placement positions 8 for placing the spindle head 6. The first detection sensor is disposed near the V-shaped support block 14 and is used to detect whether the spindle head placed at the spindle head placement position 8 is in place. The second detection sensor 153 is disposed near the placement position and is used to detect whether the machine tool slide has moved into place when the spindle head is replaced.

[0051] This linear moving head holder is located on the front side of the machine tool. When the spindle head needs to be replaced, the linear moving head holder moves to the machining area under the drive of the drive structure 3. The nozzle of the blowing structure blows away the cutting chips and cutting fluid on the spindle head on the machine tool slide. The machine tool slide moves to the spindle head placement position on the carriage, lowers the spindle head on it into the carriage, and moves it to the position where the spindle head to be installed is placed. The spindle head to be replaced is then installed. After the head replacement is completed, the drive structure 3 drives the moving carriage structure 2 and the spindle head on it to move out of the machining area. Because this linear moving head holder is located on the front side of the machine tool, the operator can observe the head replacement process from outside the machine tool operating door. The operator can manually check and monitor whether the various mechanical movements during the head replacement process are carried out according to the predetermined procedure to prevent accidental mechanical collisions or damage, ensure the safety of the operator and the machine tool equipment, and guarantee the safety of the machining process.

[0052] In a specific embodiment, such as Figure 1-3 As shown, the vehicle body is provided with a dustproof plate 16; the dustproof plate 16 is located on the side of the vehicle body 21 and is used to prevent cutting chips, cutting fluid and dust in the environment from falling on the spindle head on the vehicle body, so as to avoid contamination of the spindle head.

[0053] In a specific embodiment, such as Figure 8 As shown, the blowing structure 4 includes a nozzle 41, a gear drive structure 43, and a rotating shaft 42. The gear drive structure 43 is mounted on the protective door 7. One end of the rotating shaft 42 is connected to the gear drive structure 43, and the other end of the rotating shaft 42 is provided with the nozzle 41. When the vehicle moves into the processing area, the gear drive structure 43 drives the rotating shaft 42 to rotate, causing the nozzle to rotate towards the interface of the exchange spindle head. The nozzle 41 blows air to clean the cutting chips and cutting fluid near the interface of the exchange spindle head, ensuring that the area near the exchange spindle head is clean and preventing cutting chips from interfering with the correct installation and positioning of the spindle head. In actual applications, the rotation angle of the nozzle 41 can be set as needed.

[0054] In a specific embodiment, such as Figure 3 As shown, the base structure 1 also includes a foot adjustment device 13 disposed on the base plate 11. This device is used to fix the base plate 11 to the installation site to ensure the connection stability of the base plate 11, thereby ensuring the smooth movement of the spindle head; additionally, the vertical height of the base plate 11 can be adjusted via the foot bolt structure of the foot adjustment device.

[0055] In a specific embodiment, the driving structure 3 is a linear drive structure. In this embodiment, the linear movement structure adopts the single power source driven double-pitch double-speed linear module in Chinese Patent 202323501733.7. The bottom of the vehicle body is fixedly connected to the second lead screw nut seat in the single power source driven double-pitch double-speed linear module. When the vehicle body needs to be driven to move, the motor starts. The motor drives the first synchronous wheel and the second synchronous wheel to rotate, respectively driving the first lead screw and the second lead screw to rotate. Since the first lead screw nut seat is fixed, the motor can drive the second lead screw nut seat to linearly transmit at double pitch and double speed relative to the first lead screw nut seat. This enables the mobile headstock to move linearly at double speed along the second lead screw and the moving circular rail 12 on the base plate 11. The direction of movement of the second lead screw nut seat can be adjusted by adjusting the rotation direction of the motor's output shaft, thereby enabling the vehicle body and the main spindle head to move into or out of the machine tool processing area. The linear drive structure 3 in this application can also be set to other forms of linear drive structure, as long as it can drive the vehicle body (headstock) to move linearly.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
