Description

Technical Field

[0001] This utility model relates to the field of composite machine tool technology, and in particular to a vertical and horizontal composite machine tool structure with a third tool magazine. Background Technology

[0002] Composite machine tools are a type of multi-tasking machine tool that typically combines turning, milling, boring, and other machining functions into one unit. They can complete multiple machining operations in a single setup, thereby reducing the number of setups and improving accuracy and machining efficiency. This efficiency improvement is particularly pronounced when machining very heavy parts. Figure 11 The image shows a large boring bar, with the largest tool reaching 695mm in length and weighing 35kg. This is considered an ultra-heavy and ultra-large tool. Typically, multiple tools are installed in a tool magazine, and the entire magazine, including the tools, can weigh around 800kg. The current standard BT50 tool magazine has a maximum tool load capacity of 15kg and a maximum tool head diameter of 220mm, which is completely insufficient for storing such ultra-heavy and ultra-large tools. In actual machining processes, tool changing is currently done manually. Due to the extreme weight of the tools, it usually requires two or three people to change them, resulting in extremely high labor intensity. Furthermore, if the coordination is not perfect during tool changing, the tool can fall onto the worktable, causing damage to the worktable and guide rails. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a vertical and horizontal composite machine tool structure with a third tool magazine that can store ultra-heavy and ultra-large tools, realize automatic tool changing, greatly improve tool changing efficiency and tool changing safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vertical-horizontal composite machine tool with a third tool magazine includes a machine tool base. Each end of the machine tool base has a support, one support housing a vertical spindle box and the other a horizontal spindle box. A first tool magazine and a second tool magazine are respectively mounted on the two supports. The top surface of the machine tool base has a slide table that can feed along the X and Y directions. The third tool magazine is located on the side of the slide table. The third tool magazine includes a connecting seat, a tool holder plate mounted on the connecting seat, and several tool storage positions around the tool holder plate for storing tools. One end of the connecting seat is fixedly connected to the sliding inner end in the Y direction. The bottom of the tool holder plate has a rotational power source for driving the tool holder plate to rotate. The rotation axis of each tool in each tool storage position is parallel to the axis of the vertical spindle box.

[0006] By adopting the above technical solution: a third tool magazine is set on the side of the slide table, and the rotation axis of the tool is set parallel to the spindle of the vertical spindle box. The load-bearing capacity of the slide table is much greater than that of the load-bearing beam of the stand. The third tool magazine on the slide table can store overweight and oversized tools and can bear the weight of the entire third tool magazine of about 800 kg without affecting other performance of the machine tool. Furthermore, the tool is moved directly to the bottom of the spindle of the vertical spindle box by moving the slide table in the X and Y directions. Then, the vertical spindle box descends to connect the spindle and the tool, realizing rapid tool changing. This eliminates the need for manual tool changing and the use of robots for tool changing, greatly improving the convenience and safety of tool changing.

[0007] Preferably, the top surface of the slide is provided with a rotary worktable for workpiece positioning. The rotary worktable mounted on the slide, in conjunction with the dual spindle boxes of the composite machine tool, greatly improves the convenience and versatility of workpiece processing.

[0008] Preferably, the connecting seat is provided with a sliding seat, the rotational power is disposed on the sliding seat, and the connecting seat is provided with a translational force that drives the sliding seat to move along the Y direction. The translational force can drive the sliding seat to move along the Y direction. On the one hand, during the machining process, the workpiece can be prevented from interfering with the third tool magazine by moving the sliding seat; on the other hand, during tool changing, the tool in the third tool magazine can be quickly moved to directly below the spindle of the vertical spindle box by moving directly in the Y direction through the translational force, thereby improving tool changing efficiency.

[0009] Preferably, the sliding seat and the connecting seat are connected by a slide rail and a slider, the translational force is configured as any one of a motor, a cylinder, and a hydraulic cylinder, the rotational force is configured as a motor, and the shaft end of the translational force is connected to the sliding seat.

[0010] Preferably, each tool storage position on the tool holder disk is equipped with a tool positioning assembly. The tool positioning assembly includes two symmetrically distributed clamping arms, the middle of which is rotatably connected to the tool holder disk. An elastic element is provided between the inner ends of the clamping arms to drive the outer ends of the clamping arms to retract and clamp the tool. A clamping groove for limiting the clamping of the tool shank is formed between the outer ends of the two clamping arms. A limiting block is provided on the tool holder disk at the bottom of the clamping groove for engaging with a keyway on the tool shank. The tool and the tool positioning assembly can be quickly separated and connected via Y-axis translation, making it very convenient to use.

[0011] Preferably, the upper side of the tool holder is provided with a protective cover, the outer side of the protective cover in the Y direction is provided with a clearance opening, and the top surface of the outer side of the protective cover in the Y direction is provided with a spindle clearance groove that communicates with the clearance opening. Since the third tool magazine is set on the slide table, metal chips generated during workpiece machining are prone to remain on the tool holder. The protective cover can prevent metal chips from falling onto the tool holder. The clearance opening can, on the one hand, allow the workpiece to pass through, preventing the workpiece from interfering with the protective cover; on the other hand, it facilitates the separation of the tool from the third tool magazine. The spindle clearance groove facilitates the spindle to descend and connect directly with the tool holder.

[0012] Preferably, the tool holder disc has a tool rest position at its edge, and this tool rest position is equipped with a baffle for closing the spindle clearance groove. When the rotational power drives the tool holder disc to rotate so that the tool rest position is directly below the spindle clearance groove, the spindle clearance groove is closed by the baffle. By setting the baffle on the tool rest position, during the machining process, the tool rest position rotates to correspond with the spindle clearance groove, causing the baffle to close the spindle clearance groove, thereby preventing metal chips from entering the tool from the spindle clearance groove.

[0013] Therefore, this utility model has the following beneficial effects: (1) The third tool magazine is installed on the side of the slide table, and extra-large and extra-heavy tools can be installed in the third tool magazine to improve the processing performance of the composite machine tool; (2) Automatic tool changing is achieved by using the X and Y movement of the slide table in the composite machine tool and the Z lifting of the spindle box, which greatly reduces the modification cost of the composite machine tool; (3) Y movement is achieved by using translational force to further improve the tool changing efficiency; (4) The third tool magazine is in a closed state when not in use to prevent metal chips generated during workpiece processing from entering the tool holder and affecting the connection between the spindle and the tool holder.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.

[0026] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.

[0027] like Figures 1-10 The illustrated vertical-horizontal composite machine tool with a third tool magazine includes a machine tool base 10. Each end of the machine tool base 10 has a support 11. One support 11 has a vertical spindle head 130, and the other support 11 has a horizontal spindle head 131. The two supports 11 respectively have a first tool magazine 110 and a second tool magazine 111. The top surface of the machine tool base 10 has a slide 14 that can feed along the X and Y directions. The side of the slide 14 has a third tool magazine 2. The slide table 14 has a third tool magazine 2 on its side; the third tool magazine 2 includes a connecting seat 20, a tool holder disk 21 on the connecting seat 20, and several tool storage positions 210 around the tool holder disk 21 for storing tools 3. One end of the connecting seat 20 is fixedly connected to the sliding inner end in the Y direction. The bottom of the tool holder disk 21 is provided with a rotational power source 22 for driving the tool holder disk 21 to rotate; the rotation axis of each tool in the tool storage position 210 is parallel to the axis of the vertical spindle box 130. The top surface of the slide table 14 is provided with a rotary worktable 15 for workpiece positioning.

[0028] like Figures 6-8As shown, the connecting seat 20 is provided with a sliding seat 23, and the rotational power 22 is provided on the sliding seat 23. The connecting seat 20 is provided with a translational force 24 that drives the sliding seat 23 to move along the Y direction. The sliding seat 23 and the connecting seat 20 are connected by a slide rail and a slider. The translational force 24 is configured as any one of a motor, a cylinder, or a hydraulic cylinder, and the rotational power 22 is configured as a motor. The shaft end of the translational force 24 is connected to the sliding seat 23. In this embodiment, the translational force is configured as a cylinder.

[0029] Each tool storage position 210 on the tool holder disk 21 is equipped with a tool positioning assembly 25. The tool positioning assembly 25 includes two symmetrically distributed clamping arms 250. The middle of the clamping arms 250 is rotatably connected to the tool holder disk 21. An elastic element 251 is provided between the inner ends of the clamping arms 250 to drive the outer ends of the clamping arms 250 to retract and clamp the tool. A clamping groove 252 for clamping and limiting the tool holder is formed between the outer ends of the two clamping arms 250. A limiting block 253 for engaging with the keyway on the tool holder is provided at the bottom of the clamping groove 252 on the tool holder disk 21. A protective cover 26 is provided on the upper side of the tool holder disk 21. The protective cover 26 is mounted on the sliding seat through the bracket 28. A clearance opening 260 is provided on the Y-direction outer side of the protective cover 26. A spindle clearance groove 261 communicating with the clearance opening 260 is provided on the top surface of the Y-direction outer end of the protective cover 26. The tool holder disk 21 has an empty tool position 211 at its edge, and a baffle 27 for closing the spindle clearance groove 261 is provided at the empty tool position 211. When the rotational power 22 drives the tool holder disk 21 to rotate so that the empty tool position 211 is directly below the spindle clearance groove 261, the spindle clearance groove 261 is closed by the baffle 27. In some embodiments, the elastic element 251 is a compression spring or an elastic sheet.

[0030] like Figure 9 and Figure 10 As shown, the tool holder 21 has four tool storage slots 210, each holding four tools. A baffle is installed on one empty tool slot 211. The entire third tool magazine weighs approximately 800 kg. The third tool magazine is in the following state when not in use: Figure 5 As shown, the baffle closes the spindle clearance groove 261 on the protective cover 26 to prevent metal chips from entering the tool during machining.

[0031] One method for changing tools in the third tool magazine is as follows: When a tool change is needed, the rotary power 22 drives the tool holder disk 21 to rotate, causing the tool 3 to be replaced to rotate into the spindle clearance slot 261; at the same time, the feed power of the composite machine tool 1 drives the slide table 14 to move along the X and Y directions, so that the tool 3 in the spindle clearance slot 261 moves to be coaxial with the spindle of the vertical spindle box 130; the lifting power of the composite machine tool 1 drives the vertical spindle box 130 to descend, and the spindle descends to connect with the tool 3 in the spindle clearance slot 261; the feed power of the composite machine tool 1 drives the slide table 14 to move inward along the Y direction, so that the tool separates from the third tool magazine 2 from the clearance port 260, realizing the tool change; then the rotary power 22 drives the tool holder disk 21 to rotate to the baffle 27 to close the spindle clearance slot 261.

[0032] The second tool changing method of the third tool magazine is as follows: When a tool change is required, the rotary power 22 drives the tool holder disk 21 to rotate, causing the tool 3 to be replaced to move into the spindle clearance slot 261. At the same time, the feed power of the composite machine tool 1 drives the slide table 14 to move along the X direction, so that the axis of the tool 3 in the spindle clearance slot 261 is coplanar with the axis of the spindle in the Y direction. The translational force 24 drives the sliding seat 23 to move outward in the Y direction, so that the axis of the tool 3 in the spindle clearance slot 261 moves to be collinear with the spindle. The lifting power of the composite machine tool 1 drives the vertical spindle box 130 to descend, and the spindle descends to connect with the tool 3 in the spindle clearance slot 261. The translational force 24 drives the sliding seat 23 to move inward in the Y direction, so that the tool separates from the third tool magazine 2 from the clearance port 260, realizing the tool change. Then, the rotary power 22 drives the tool holder disk 21 to rotate to the baffle 27 to close the spindle clearance slot 261.

[0033] The two tool changing methods described above are for situations where there is no tool on the spindle of the vertical spindle box. When the spindle of the vertical spindle box has a tool, the tool needs to be returned to the first, second, or third tool magazine first, and then the tool should be retrieved according to the above method: If the tool is in the first or second tool magazine, it should be returned to the main tool magazine using the normal method (CNC machine tools can achieve automatic tool changing between the main tool magazine and the main tool magazine); if the tool is in the third tool magazine, the empty tool positioning assembly should be rotated to the spindle clearance slot, the spindle with the tool should be lowered to the preset position, the tool holder should move outward along the Y direction so that the clamping slot in the tool positioning assembly clamps the tool, the vertical spindle box should rise and separate from the tool, and the tool should enter the third tool magazine.

[0034] This type of composite machine tool is equipped with a third tool magazine, which can store heavy and large tools to meet the composite machining needs of large parts; it eliminates the workload of manual tool changing and the resulting safety hazards.
