Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically to a gantry-type multi-spindle head device. Background Technology

[0002] In the machining industry, the traditional single-spindle machining method for processing large workpieces has problems such as low efficiency and scattered processes. In order to meet the needs of large-scale production, machining devices equipped with multiple spindles are set up to achieve synchronous processing at multiple workstations.

[0003] A search revealed a patent document with publication number CN211540023U, which discloses a multi-spindle gantry-type metal processing center. This device optimizes its structure by incorporating a gantry frame, top, fixed frame, base plate, spindle, pre-reserved blocks, pre-reserved slots, locking bolts, and welding heads. By having multiple spindles, different functional processing heads can be mounted on different spindles, enabling the device to perform various processing operations such as welding and drilling simultaneously, thus enhancing its functionality. Specifically, the user can utilize the interlocking connection structure between the pre-reserved blocks and pre-reserved slots, along with the locking action of the locking bolts, to mount processing heads with different functions at the bottom of the spindle. This allows the device to perform various processing functions and facilitates easy disassembly and maintenance of the processing heads.

[0004] However, the distance between the multiple spindle heads inside the above device is fixed. When multiple workpieces that need to be processed occupy a large area, the spindle heads cannot effectively cooperate with the workpieces, resulting in the workpieces not being processed effectively and reducing processing efficiency.

A first spindle head and multiple second spindle heads are provided on the bottom of the horizontal plate. The first spindle head is fixedly connected to the bottom of the horizontal plate. A sleeve plate is provided on the top of the second spindle head. A movable block is slidably mounted inside the sleeve plate.

A motor is fixedly installed on the outer wall of the horizontal plate, and the output end of the motor passes through the mounting groove and is fixedly connected to the adjusting screw. The adjusting screw is threaded inside the plurality of moving blocks.

[0010] Preferably, the adjusting screw has two connected first threads and second threads on its rod wall, and the thread pitch of the first thread is greater than the thread pitch of the second thread.

[0011] Preferably, an adjusting rod is slidably inserted through the side of the sleeve plate, and the side wall of the moving block has multiple spaced adjusting grooves that cooperate with the adjusting rod for insertion. A spring is sleeved on the rod wall of the adjusting rod, and the two ends of the spring are fixedly connected to the adjusting rod and the sleeve plate respectively.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a gantry-type multi-spindle head device.

[0025] This utility model provides, for example Figures 1-3 The gantry-type multi-spindle head device shown includes a processing platform 1 and a gantry frame 2 fixedly mounted on the top of the processing platform 1. A movable frame 3 is provided on the top of the gantry frame 2, and a horizontal plate 4 is fixedly mounted on the bottom of the movable frame 3. A first spindle head 5 and multiple second spindle heads 6 are provided on the bottom of the horizontal plate 4. The first spindle head 5 is fixedly connected to the bottom of the horizontal plate 4. A sleeve plate 7 is provided on the top of the second spindle head 6. A movable block 8 is slidably provided inside the sleeve plate 7. An installation ring 15 is fixedly mounted on the bottom of the sleeve plate 7. The top of the second spindle head 6 is inserted into the installation ring 15, and a quick-release bolt 16 is threaded between the top of the second spindle head 6 and the side of the installation ring 15.

[0026] A spacing adjustment mechanism for driving the second spindle head 6 to move is provided between multiple moving blocks 8 and the horizontal plate 4. The bottom of the horizontal plate 4 is provided with a mounting groove. The top of the moving block 8 contacts and fits with the top of the inner wall of the mounting groove. An adjusting screw 9 is rotatably inserted through the side of the mounting groove. The rod wall of the adjusting screw 9 is provided with two connected first threads and second threads. The thread pitch of the first thread is greater than the thread pitch of the second thread. A motor 10 is fixedly installed on the outer wall of the horizontal plate 4. The output end of the motor 10 passes through the mounting groove and is fixedly connected to the adjusting screw 9. The adjusting screw 9 is threaded inside the multiple moving blocks 8.

[0027] To allow for further fine lateral adjustment of the spindle head positions based on workpiece specifications after adjusting the spacing between multiple spindle heads, such as... Figure 2-3As shown, an adjusting rod 11 is slidably inserted through the side of the sleeve plate 7, and multiple spaced adjusting grooves 12 are opened on the side wall of the moving block 8 to cooperate with the adjusting rod 11. A spring 13 is sleeved on the rod wall of the adjusting rod 11, and the two ends of the spring 13 are fixedly connected to the adjusting rod 11 and the sleeve plate 7 respectively. A pull hole 14 is opened on the rod wall of the adjusting rod 11.

[0028] Working principle: When it is necessary to process workpieces of different sizes, the motor 10 on the outer wall of the horizontal plate 4 is started first. The output shaft of the motor drives the adjusting screw 9 to rotate. Since the adjusting screw 9 has two sections of threaded first thread and second thread with different thread pitches (the first thread pitch is greater than the second thread), and multiple moving blocks 8 are respectively engaged with the two sections of thread, when the adjusting screw 9 is rotated, the moving blocks 8 connected to the first thread and the second thread will move towards or away from each other at different speeds, thereby driving the sleeve plate 7 and the second spindle head 6 to move laterally along the mounting groove at the bottom of the horizontal plate, quickly adjusting the distance between the first spindle head 5 and multiple second spindle heads 6 to adapt to the processing range of the workpiece.

[0029] When fine adjustment of the spindle head position is required, pull the adjusting rod 11 to disengage it from the adjusting groove 12 on the side wall of the moving block 8 (at this time, the spring 13 is compressed), slide the sleeve 7 laterally to the appropriate position, release the adjusting rod 11, and under the action of the spring force, the adjusting rod 11 is reinserted into the adjusting groove 12 of the moving block 8 and fixed, thus completing the fine adjustment of the spindle head position.

[0030] After adjustment, each spindle head can be started synchronously or independently according to processing requirements to perform milling, drilling and other operations on the workpiece. During processing, the tool or module of the second spindle head 6 can be quickly replaced by quick-release bolt 16 to improve processing efficiency.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
