[0031] Combination Figure 1-4 As shown, the embodiment of the present disclosure provides a tool holder for a vertical lathe, comprising: a fixture body 100, a tool holder 200 and a tool tightening assembly 300. A plurality of tool holders 200 are provided on the lower side wall of the fixture body 100; the tool tightening assembly 300 is movably connected to the side wall of the fixture body 100, and one end of the tool tightening assembly 300 passes through the fixture body 100 and extends into the tool holder 200, and each tool holder 200 is provided with a tool tightening assembly 300; wherein, a tool can be detachably connected to each tool holder 200, and one end of the tool tightening assembly 300 extends into the corresponding tool holder 200 to lock the tool in the tool holder 200.
[0032] The vertical lathe tool holder provided by the embodiment of the present disclosure is used, and a plurality of tool holders 200 are arranged on the lower side wall of the fixture body 100, and a tool can be detachably installed in each tool holder 200. The tool in the tool holder 200 is locked by the tool tightening assembly 300 corresponding to each tool holder 200, and then the fixture body 100 is installed on the vertical lathe for use. During the processing of parts, different tools on the fixture body 100 can be used alternately according to the processing requirements to cut the parts, thereby reducing the number of shutdowns for tool change during the processing of parts, reducing the time spent on tool change, and improving the processing efficiency.
[0033] Optionally, two tool sleeves 200 are provided. In this way, each tool sleeve 200 can be detachably connected to a turning tool, and the two turning tools can be used alternately during the processing of the parts, thereby reducing the number of shutdowns for tool changes during the processing, reducing the time spent on tool changes, and improving processing efficiency. In addition, two tool sleeves 200 are provided, which is a moderate number, reducing the manufacturing difficulty of the fixture body 100.
[0034] Optionally, the lower side wall of the fixture body 100 is rectangular. In this way, the fixture body 100 is relatively regular, the production of the fixture body 100 is relatively simple, and the relatively regular fixture body 100 has a clear boundary, which reduces interference with parts during processing.
[0035] Optionally, the axis of each tool sleeve 200 is perpendicular to the lower side wall of the fixture body 100. In this way, the axis of each tool sleeve 200 is perpendicular to the lower side wall of the fixture body 100. After the turning tool is installed in the tool sleeve 200, the axis of the turning tool is also perpendicular to the lower side wall of the fixture body 100. The turning tool installed in the fixture body 100 can process the part in the vertical direction, reducing the difficulty of tool alignment during the part processing process.
[0036] Optionally, the tool sleeve 200 is a groove-shaped structure opened on the lower side wall of the fixture body 100, and the tool sleeve 200 opens a connection hole along the lower side wall of the fixture body 100 toward the inner side of the fixture body 100, and the connection hole is used to install a turning tool. In this way, the tool sleeve 200 protrudes from the lower side wall of the fixture body 100, and after the turning tool is installed in the tool sleeve 200, the turning tool is relatively far away from the lower side wall of the fixture body 100, thereby reducing the risk of interference of the fixture body 100 during the process of processing parts.
[0037] Combination Figure 2 As shown, optionally, the height of the tool sleeve 200 is less than or equal to two-thirds of the height of the fixture body 100, and greater than or equal to one-quarter of the height of the fixture body 100. In this way, when the height of the tool sleeve 200 is greater than two-thirds of the height of the fixture body 100, the height of the tool sleeve 200 is relatively high, which reduces the strength of the fixture body 100 itself, the installation depth of the turning tool is too large, and the tool handle of the turning tool and the tool sleeve 200 are poorly compatible. When the height of the tool sleeve 200 is less than one-quarter of the height of the fixture body 100, the height of the tool sleeve 200 is low. After the turning tool is installed, the contact area with the tool handle is small, and the support strength for the turning tool is relatively low, which increases the risk of the turning tool falling off and shaking. It can be seen that the range in which the height of the tool sleeve 200 is less than or equal to two-thirds of the height of the fixture body 100 and greater than or equal to one-quarter of the height of the fixture body 100 is relatively reasonable. The contact area between the tool sleeve 200 and the tool handle is relatively large, which increases the support strength of the tool sleeve 200 for the turning tool, reduces the risk of the turning tool falling off and shaking, and also improves the inherent strength of the fixture body 100.
[0038] Optionally, the height of the tool sleeve 200 is equal to one third of the height of the fixture body 100. In this way, when the turning tool is installed in the tool sleeve 200, the contact area between the tool sleeve 200 and the tool handle is relatively large, which increases the support strength of the tool sleeve 200 for the turning tool, reduces the risk of the turning tool falling off and shaking, and also improves the strength of the fixture body 100 itself.
[0039] Optionally, the tool sleeve 200 is provided at the middle position of the lower side wall of the fixture body 100 along the short side direction thereof. In this way, the tool sleeve 200 is relatively centered, and when the turning tool is installed in the tool sleeve 200 to process the part, the force on the fixture body 100 is relatively uniform, thereby forming a stable support for the turning tool.
[0040] Optionally, the tool tightening assembly 300 includes a tightening bolt 310. The tightening bolt 310 is connected to the side wall of the fixture body 100 by threads, and one end of the tightening bolt 310 passes through the fixture body 100 and extends into the corresponding tool sleeve 200. In this way, by rotating the tightening bolt 310, the tightening bolt 310 is driven away from the axis of the tool sleeve 200, and then the handle of the turning tool is placed into the tool sleeve 200, and the tightening bolt 310 is rotated in the opposite direction again, so that the tightening bolt 310 is close to and close to the handle of the turning tool, and the tightening bolt 310 then cooperates with the tool sleeve 200 to lock the turning tool. By providing the tightening bolt 310 to lock the turning tool in the tool sleeve 200, the efficiency of disassembly and assembly of the turning tool is improved while improving the locking stability of the turning tool.
[0041] Optionally, each tool sleeve 200 is provided with a corresponding fastening bolt 310. In this way, the corresponding turning tool can be clamped or loosened by turning a fastening bolt 310, and the speed of changing the turning tool is relatively fast, which reduces the time required for tool change and improves the efficiency of tool change.
[0042] Optionally, a plurality of countersunk threaded holes 110 are provided on the side wall of the fixture body 100, each countersunk threaded hole 110 is provided corresponding to a tool sleeve 200, and each countersunk threaded hole 110 passes through the fixture body 100 and extends into the corresponding tool sleeve 200; each countersunk threaded hole 110 is threadedly connected to a fastening bolt 310. In this way, when the fastening bolt 310 is locking the turning tool handle, the head of the fastening bolt 310 is located at the head of the countersunk threaded hole 110, reducing the distance that the fastening bolt 310 protrudes from the side wall of the fixture body 100, and reducing the risk of the fastening bolt 310 interfering with the processed parts.
[0043] Optionally, two countersunk threaded holes 110 and two fastening bolts 310 are provided. In this way, the number of countersunk threaded holes 110 and two fastening bolts 310 corresponds to the number of the tool sleeve 200.
[0044] Optionally, the axis of the fastening bolt 310 is perpendicular to the axis of the corresponding tool sleeve 200. In this way, the axis of the fastening bolt 310 is perpendicular to the axis of the tool sleeve 200. When a turning tool is installed in the tool sleeve 200, the fastening bolt 310 clamps and fixes the turning tool perpendicularly to the axis of the turning tool. The length required for the fastening bolt 310 to pass through the fixture body 100 is relatively short, thereby reducing the production cost of the fastening bolt 310.
[0045] Optionally, the axis of the countersunk threaded hole 110 is perpendicular to the axis of the corresponding tool sleeve 200. In this way, the axis of the countersunk threaded hole 110 is perpendicular to the axis of the corresponding tool sleeve 200, which corresponds to the axis of the fastening bolt 310 and the axis of the corresponding tool sleeve 200, and reduces the length required for the countersunk threaded hole 110 to pass through the fixture body 100.
[0046] Combination Figure 3 As shown, optionally, the fixture body 100 includes: a mounting seat 120 and a connecting block 130. Two connecting blocks 130 are provided, which are symmetrically installed at the two ends of the top of the mounting seat 120; wherein, a plurality of tool sleeves 200 are provided on the lower side wall of the mounting seat 120, and the tool tightening assembly 300 is movably connected to the side wall of the mounting seat 120. In this way, the mounting seat 120 is connected to the connecting block 130, and the connecting block 130 is assembled to the vertical machining center, and then the turning tool installed in the tool sleeve 200 is assembled to the vertical lathe to process the parts. The connection with the vertical lathe through two connecting blocks 130 has higher stability.
[0047] Optionally, a plurality of countersunk threaded holes 110 are provided on the side wall of the mounting seat 120, each countersunk threaded hole 110 is provided corresponding to a tool sleeve 200, and each countersunk threaded hole 110 passes through the mounting seat 120 and extends into the corresponding tool sleeve 200; each countersunk threaded hole 110 is threadedly connected to a fastening bolt 310. In this way, when the fastening bolt 310 is locking the turning tool handle, the head of the fastening bolt 310 is located at the head of the countersunk threaded hole 110, reducing the distance that the fastening bolt 310 protrudes from the side wall of the fixture body 100, and reducing the risk of the fastening bolt 310 interfering with the processed parts.
[0048] Optionally, the upper side of each connection block 130 is higher than the upper side of the mounting seat 120. In this way, before processing the parts, the connection block 130 and the mounting seat 120 are placed on the table, with the connection block 130 at the bottom and the mounting seat 120 facing up, and then the turning tool is installed in the tool sleeve 200, and the turning tool is locked by the fastening bolt 310. At this time, the connection block 130 is in contact with the table, and there is a gap between the mounting seat 120 and the table, which is convenient for the user to lift the mounting seat 120 and the connection block 130 through the gap and assemble them on the vertical lathe.
[0049] Optionally, each connection block 130 protrudes from the side wall of the corresponding mounting seat 120. In this way, the connection block 130 is installed on the vertical lathe, and the span of the connection position between the vertical lathe and the connection block 130 is large, which improves the stability of the connection.
[0050] Combination Figure 4 As shown, optionally, each connection block 130 is provided with an assembly hole 140. In this way, the connection block 130 is installed on the vertical lathe by matching the T-bolt with the assembly hole 140 and the T-bolt is connected to the vertical lathe.
[0051] Optionally, each connection block 130 is provided with a plurality of assembly holes 140. Thus, each assembly hole 140 is provided with a T-bolt, the T-bolt cooperates with the assembly hole 140, and the T-bolt is connected to the vertical lathe, so that the connection block 130 is installed on the vertical lathe, and there are more connection positions, thereby improving the stability of the connection.
[0052] Optionally, the axis of the assembly hole 140 is perpendicular to the lower side of the mounting seat 120 .
[0053] Optionally, the assembly hole 140 passes through the connecting block 130. In this way, the T-bolt passes through the assembly hole 140, and the T-bolt is connected to the vertical lathe, thereby installing the connecting block 130 on the vertical lathe.
