Description

Technical Field

[0001] This utility model relates to the field of machine tools, and in particular to a tool mounting structure and a machine tool including the tool mounting structure. Background Technology

[0002] The spindle of a boring machine is typically tapered, with an internal lasing plate (or gantry) for clamping the tool. However, boring machines handle different types of tools, each requiring a different lasing plate. Currently, the lasing plate on the spindle is of a fixed type. Changing to a different tool requires replacing the entire boring machine or removing the existing lasing plate from the spindle and replacing it with the corresponding type. However, replacing an lasing plate installed inside the spindle is difficult, leading to low production efficiency. Utility Model Content

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figures 1 to 3 The tool mounting structure of this utility model includes a variable diameter sleeve 10, a pad 20, a first fastener 30, a positioning key 40, a second fastener 50, a first lasing rod 60, a first pull claw 70, a connecting component 80, a second lasing rod 90, and a third fastener 100.

[0027] The reducing sleeve 10 includes a mounting end 11 and a plug-in portion 12. The plug-in portion 12 extends from one side of the mounting end 11 and is integrally formed with the mounting end 11. Specifically, the mounting end 11 is cylindrical, and the plug-in portion 12 is conical. The mounting end 11 is provided with a keyway 110 and a mounting hole 111. The keyway 110 is located on the side of the mounting end 11 away from the plug-in portion 12. The keyway 110 is used to install a positioning key 40, which is used to position the tool holder. The mounting hole 111 is provided along the axial direction of the reducing sleeve 10 and is conical, used to install the tool holder. The reducing sleeve 10 also has through holes for installing a first lasing 60, a first pull claw 70, a connecting assembly 80, and a second lasing 90. The through holes are located on the axial direction of the reducing sleeve 10 and communicate with the mounting hole 111.

[0028] The pad 20 is fixed to the mounting end 11 near the insertion part 12 by the third fastener 100. Specifically, the shape and size of the pad 20 correspond to the mounting end 11. When the tool mounting structure is detachably fixed to the spindle 300, the pad 20 abuts against the end of the spindle 300 to prevent damage to the reducing sleeve 10.

[0029] The first fastener 30 passes through the mounting end 11 and the pad 20 and cooperates with the end of the spindle 300 to realize the detachable connection between the tool mounting structure and the spindle 300.

[0030] The positioning key 40 is installed in the keyway 110 and fixed by the second fastener 50. The positioning key 40 positions the tool holder 200 installed in the mounting hole 111.

[0031] The first Latin 60 is installed in the through hole of the reducing sleeve 10, and the first Latin 60 is used to connect with the tool holder 200 in the mounting hole 111.

[0032] The first pull claw 70 is installed in the through hole of the reducing sleeve 10. The first pull claw 70 is located on one side of the first lasing sleeve 60 and is on the same straight line as the first lasing sleeve 60. The first pull claw 70 and the first lasing sleeve 60 cooperate to tighten the first lasing sleeve 60.

[0033] The connecting assembly 80 includes a first adjusting pad 81, a connecting sleeve 82, an elastic element 83, an end sleeve 84, and a second adjusting pad 85. The connecting assembly 80 connects a first pull claw 70 and a second Latin joint 90. The connecting sleeve 82 is coaxially arranged with the first pull claw 70 and the second Latin joint 90, and has a hollow structure with internal threads on the inner walls at both ends. The tail of the first pull claw 70 is threadedly connected to the connecting sleeve 82, and the end of the second Latin joint 90 is threadedly connected to the connecting sleeve 82. The first adjusting pad 81 is sleeved on the first pull claw 70 and located between the first pull claw 70 and the connecting sleeve 82. The end sleeve 84 is fixed to the end of the insertion part 12 by external threads, and the connecting sleeve 82 is slidably mounted on the end sleeve 84. The two ends of the elastic element 83 abut against the connecting sleeve 82 and the end sleeve 84, respectively. Specifically, the elastic element 83 is a spring, and the spring's extension direction is the same as the axial direction of the reducing sleeve. The second adjusting pad 85 is sleeved on the second Latin joint 90 and located between the second Latin joint 90 and the connecting sleeve 82.

[0034] The second Latin jack 90 is used to connect with the second pull jaw 500 inside the machine tool spindle 300. The second Latin jack 90 is a different model from the first Latin jack 60 to accommodate the handles of different types of cutting tools.

[0035] Please continue reading. Figure 4When using the tool mounting structure, during boring machine operation, the handle of the first tool holder type tool is mounted on the spindle 300 and connected to the second pull jaw 500. The pull bar 400 is connected to the second pull jaw 500, and the pull bar 400 drives the second pull jaw 500 to tighten the first tool holder type tool. When it is necessary to replace the second tool holder type tool, the tool mounting structure is installed on the end of the spindle 300. At this time, the first fastener 30 passes through the mounting end 11 and the pad 20 and cooperates with the end of the spindle 300 to realize the detachable connection between the tool mounting structure and the spindle 300. The pad 20 abuts against the end of the spindle 300, and the second pull jaw 90 cooperates with the second pull jaw 500. The tool holder 200 of the second tool holder type tool is mounted in the tapered mounting hole 111, and the tool holder 200 is connected to the first pull jaw 60. The positioning key 40 positions the tool holder 200 with the mounting end 11.

[0036] When using the second type of cutter, when the drawbar 400 is pushed forward, the second pull pawl 500 disengages, the second lasing 90 moves forward under the elastic force of the elastic element 83, the first pull pawl 70 disengages, the first lasing 60 moves forward under force, and the cutter shank 200 of the second type of cutter disengages. When the drawbar 400 moves backward, the second pull pawl 500 tightens the second lasing 90, the second lasing 90 drives the first pull pawl 70 to move backward and tighten the first lasing 60, and the first lasing 60 tightens the cutter shank 200.

[0037] In this utility model, when the machine tool uses a tool with a first type of tool holder, the second pull jaw 500 connects to the first type of tool to achieve clamping; when the machine tool needs to change to a tool with a different type of tool holder, the tool mounting structure is directly installed on the end of the spindle 300, the second pull jaw 90 cooperates with the second pull jaw 500 inside the spindle 300, and the first pull jaw 60 connects to the tool holder 200 of the new tool, realizing the replacement of different tools, which is simple to operate.

[0038] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
