Technical Field

[0001] The utility model relates to the technical field of lathe processing, in particular to a device for adding a lathe tool holder to a horizontal grinding frame of a vertical grinder. Background Art

[0002] At present, vertical lathes are mainly used for rough machining of large parts, while vertical grinders are used for fine machining of the parts. After rough machining, the parts need to be clamped twice on the vertical grinder, so more margin will be reserved for the vertical grinder.

[0003] However, the overall accuracy of the vertical grinder is higher than that of the vertical lathe, and the grinding feed of the grinding wheel is much smaller than the feed of the turning tool. Usually, the grinding feed is between 0.005-0.03mm, while the fine feed of the turning tool can reach 0.1-0.5mm. Therefore, the grinding efficiency is much lower than that of turning. Summary of the invention

[0004] To this end, the utility model provides a device for adding a turning tool holder to a horizontal grinding frame of a vertical grinder, which can first perform a large margin fine turning process and then perform a final grinding process to improve the processing efficiency of the machine tool.

[0031] Reference Figure 1 , Figure 2 As shown, the utility model is a device for adding a tool holder to a horizontal grinding frame of a vertical grinder, wherein the vertical grinder comprises a horizontal grinding frame capable of moving in a horizontal lateral direction, including:

[0032] A vertical slide plate 1 is slidably connected to the horizontal grinding frame in a vertical direction;

[0033] A connecting structure connected to the vertical slide plate 1;

[0034] A grinding mechanism, mounted on the connecting structure, the grinding mechanism comprising a horizontal grinding spindle 4 and a grinding wheel 5 mounted on the horizontal grinding spindle 4;

[0035] The turning tool 9 mechanism is installed on the connecting structure and is located beside the grinding mechanism. The turning tool 9 mechanism includes a turning tool holder 6, a turning tool seat 7 installed on the turning tool holder 6, and a turning blade 8 installed on the turning tool seat 7.

[0036] It should be understood that the horizontal grinding frame can be installed on the beam of the vertical grinding machine through a horizontal slide and a horizontal guide rail, and its movement can be driven by a servo screw mechanism (or other linear modules). In this way, the grinding and turning positions can be accurately positioned in the horizontal plane; and the vertical slide 1 can be installed on the horizontal grinding frame through a vertical guide rail, and its movement can also be driven by a servo screw mechanism or other linear modules) to adjust the position in the vertical direction. Therefore, the grinding and turning positions can be accurately adjusted in the vertical direction.

[0037] The turning tool 9 mechanism is mainly used for fine turning with large allowance, and the grinding mechanism can finely grind the workpiece surface through the rotation of the grinding spindle and the grinding wheel 5.

[0038] By effectively combining turning and grinding on the vertical grinder, both efficient roughing and grinding can be performed, greatly improving the processing efficiency and quality.

[0039] In one embodiment, the axis of the horizontal grinding spindle 4 extends in a horizontal transverse direction. Through the rotation of the grinding spindle, the grinding wheel 5 can perform fine grinding on the surface of the workpiece.

[0040] In one embodiment, the connection structure includes a base 2 mounted on a vertical plane of the vertical slide 1 by bolts and a grinding frame 3 mounted on the base 2 .

[0041] In one embodiment, a mounting hole for mounting the horizontal grinding spindle 4 is provided at the lower portion of the grinding frame 3. The horizontal grinding spindle 4 can be conveniently mounted and fixed to ensure its precise positioning and stable operation.

[0042] In one embodiment, the tool holder 6 is mounted on the lower end surface of the grinding frame 3 and is located at the lower side of the horizontal grinding spindle 4 .

[0043] The turning blade 8 is mounted on one end of the turning blade seat 7 close to the grinding wheel 5. It can be understood that the feeding direction of the turning blade 8 in the horizontal direction is parallel to the horizontal grinding spindle 4. The position design of the turning blade 8 and the grinding wheel 5 allows grinding to be carried out directly after turning is completed without re-adjusting the position of the workpiece.

[0044] The tool rest 6 and the grinding frame 3 are connected with bolts and keys 10, which ensure the stability and positioning accuracy of the tool rest 6 and facilitate disassembly, assembly and maintenance.

[0045] The above installation position is convenient for cooperating with the grinding spindle when performing large-residue turning. The turning blade 8 is installed at one end of the turning tool seat 7 close to the grinding wheel 5.

[0046] In one embodiment, a grinding chuck for mounting the grinding wheel 5 is installed at the front end of the horizontal grinding spindle 4 .

[0047] Workflow:

[0048] After the parts to be processed are installed on the workbench of the vertical grinder, the drive mechanism of the machine tool's horizontal grinding frame and vertical slide 1 is started:

[0049] Through the movement of the horizontal grinding frame and the vertical slide 1, the turning tool holder 6 follows the vertical slide 1 to move to a predetermined processing position;

[0050] According to the processing requirements, adjust the position of the blade to reach the processing area, and set the processing parameters, including cutting speed, feed rate, etc.;

[0051] During turning, the turning tool 9 performs large-residue turning processing on the workpiece by horizontal reciprocating and vertical cutting. In this process, by controlling the horizontal and vertical movement of the turning tool holder 6, efficient cutting of the workpiece surface is achieved;

[0052] After turning, a small amount of allowance is reserved;

[0053] The grinding spindle is started to rotate the grinding wheel 5 at high speed, and the grinding wheel 5 performs precision grinding on the workpiece to meet the final size and surface accuracy requirements.

[0054] Through the above steps, the combination of turning and grinding processes is realized on the same machine tool, which not only improves the processing efficiency but also ensures the final processing accuracy.

[0055] Large-residue turning and precision grinding can be completed in one clamping, reducing the time for repeated clamping and tool setting.

[0056] Rough machining and finishing are performed on the same machine tool to avoid positioning errors caused by multiple clamping, thus ensuring the final machining accuracy.

[0057] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
