Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining, specifically to an integrated tool holder for hole machining. Background Technology
[0002] A Swiss-type lathe is a precision machining tool, also known as a sliding headstock CNC lathe or a longitudinal cutting lathe. Its working principle is to continuously process the workpiece by rotating the spindle and feeding the cutting tool. During the machining process, the workpiece moves along the spindle axis, while the cutting tool performs cutting movements in the radial and axial directions, thereby realizing various machining operations on the parts, such as turning, drilling, boring, and tapping.
[0003] The cutting tool is connected to the machine tool via a tool holder. The tool holder provides the foundation and fixed position for the tool. The installation position of the tool holder on the machine tool and its own accuracy determine the initial position and movement trajectory of the tool during the machining process. Moreover, through the precise installation and adjustment of the tool holder, it can be ensured that the tool is accurately aligned with the workpiece during machining to achieve the required cutting motion.
[0004] Some products have parts with both straight holes and angled holes. However, the position of the existing drill bit relative to the tool holder is mostly fixed, so it can only machine one type of hole, either straight or angled. If the other type of hole is to be machined, an additional tool holder is required to clamp the drill bit. This not only affects the machining efficiency, but the additional tool holder is also unable to guarantee the positional accuracy between the straight and angled holes. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an integrated tool holder for hole machining. The holder has a first tool hole and a second tool hole for clamping the tool. The tool can be installed on the holder through the first tool hole for machining straight holes, and the tool can be installed on the holder through the second tool hole for machining oblique holes.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] An integrated tool holder for hole machining includes a frame body with a clamping station. The clamping station includes a first tool hole and a second tool hole for clamping a tool. The first tool hole is vertically formed on the frame body, and the second tool hole is inclinedly formed on the frame body.
[0008] Optionally, the front end of the frame is provided with a groove, the bottom surface of the groove is provided with a fastening hole, and the fastening hole communicates with the second knife hole.
[0009] Optionally, the fastening hole is perpendicular to the axis of the second cutting hole, and a locking component for fixing the cutting tool in the first cutting hole is provided on one side of the groove.
[0010] Optionally, the locking assembly includes a locking hole communicating with the first knife hole. A locking groove is provided on one side of the locking hole, and a second locking hole is provided on the other side. A locking block is provided in the locking groove, and a first locking hole corresponding to the second locking hole is provided on the locking block.
[0011] Optionally, a shoulder is provided at the top of the frame near the edge, and the shoulder has a mounting hole, which is perpendicular to the axis of the first knife hole.
[0012] Optionally, the frame, the shoulder rest, and the locking block are integrally molded.
[0013] Optionally, the tool includes a handle, with a drill bit mounted at the end of the handle. The handle is located within the first cutting hole and / or the second cutting hole, and the drill bit is located outside the frame.
[0014] Optionally, there are two clamping stations, and the two clamping stations are symmetrically distributed on the frame.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] In this invention, the cutting tool is mounted on the frame through the first cutting hole and can be used to process straight holes. The cutting tool is mounted on the frame through the second cutting hole and can be used to process inclined holes. Both are mounted on the tool holder at the same time, so there is no need to add an extra tool holder or reclamp. It can be used to process both inclined and straight holes at the same time, which improves the efficiency of hole processing and ensures the positional accuracy of straight and inclined holes.

Detailed Implementation
[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0025] like Figure 6 As shown, the tool 13 includes a tool holder 131, and a drill bit 132 is installed at the end of the tool holder 131. The tool holder 131 is mounted on a tool holder, and the drill bit 132 is driven to rotate by a motor to complete the drilling work.
[0026] like Figures 1-5 As shown, an integrated tool holder for hole machining includes a frame 1, on which a clamping station is provided. The clamping station includes a first tool hole 3 and a second tool hole 4 for clamping a tool 13. The first tool hole 3 is vertically opened on the frame 1, and the second tool hole 4 is inclinedly opened on the frame 1.
[0027] The top surface of the frame 1 is a plane. The axis of the first cutting hole 3 is perpendicular to the top surface of the frame 1, and the axis of the second cutting hole 4 intersects the top surface of the frame 1 at an angle not of 90 degrees. The cutting tool 13 is mounted on the frame 1 through the first cutting hole 3 and can be used to process straight holes. The cutting tool 13 is mounted on the frame 1 through the second cutting hole 4 and can be used to process inclined holes. Both are mounted on the tool holder at the same time, so there is no need to add an extra tool holder or re-clamp. It can be used for processing inclined holes and straight holes at the same time, which improves the efficiency of hole processing and ensures the positional accuracy of straight holes and inclined holes.
[0028] The front end of the frame 1 is provided with a groove 11, and the bottom surface of the groove 11 is provided with a fastening hole 12, which is connected to the second cutter hole 4. After the cutter handle 131 is inserted into the second cutter hole 4, the fastening screw is screwed into the fastening hole 12 until the end of the fastening screw is firmly pressed against the outer circumferential surface of the cutter handle 131, thereby achieving the fixed installation of the cutter 13 in the second cutter hole 4.
[0029] Furthermore, the bottom surface of the groove 11 is parallel to the axis of the second cutting hole 4, and the fastening hole 12 is perpendicular to the axis of the second cutting hole 4. This structure ensures that the screw is perpendicular to the tool holder 131, so that the thread locking force between the screw and the fastening hole 12 is perpendicular to the tool holder 131, ensuring its stability when clamped on the tool holder.
[0030] After the tool holder 131 is inserted into the second tool hole 4, the drill bit 132 at its end is located on the outside of the frame 1 to facilitate the machining of inclined holes; and each second tool hole 4 is provided with at least two fastening holes 12 to ensure that the tool 13 can be firmly clamped on the tool holder.
[0031] As described above, a locking component is provided on one side of the groove 11, which is used to fix the tool 13 in the first tool hole 3.
[0032] The locking assembly includes a locking hole 6, a locking groove 7, a locking block 8, a first locking hole 9, and a second locking hole 10. The locking hole 6 is located at the front end of the frame 1, on one side of the groove 11, and is connected to the first cutting hole 3. The locking groove 7 is located on one side of the locking hole 6. The second locking hole 10 is located on the side of the locking hole 6 opposite to the locking groove 7. The locking block 8 is disposed in the locking groove 7. The first locking hole 9 is located on the locking block 8 and is coaxial with the second locking hole 10.
[0033] After the tool holder 131 is inserted into the first tool hole 3, the drill bit 132 is located on the outside of the frame 1 to facilitate the machining of straight holes; then the end of the screw is screwed through the first locking hole 9 into the second locking hole 10. The first locking hole 9 is close to the end of the locking block 8. By turning the screw, the locking block 8 can be bent and deformed, which reduces the minimum inner diameter of the first tool hole 3, thereby firmly fixing the tool holder 131 in the first tool hole 3.
[0034] There are gaps between the two sides of the locking block 8 and the locking groove 7 so that the end can bend and deform after being subjected to force. The root of the locking block 8 is connected to the frame 1 and extends into the first cutter hole 3. The side wall of the locking block 8 is part of the inner wall of the first cutter hole 3. When it bends, it can cause the minimum inner diameter of the first cutter hole 3 to shrink.
[0035] Furthermore, a shoulder 2 is provided near the edge of the top of the frame 1. The shoulder 2 has a mounting hole 5, and the axis of the mounting hole 5 is perpendicular to that of the first tool hole 3. The shoulder 2 protrudes from the top of the frame 1, and the frame 1 can be connected to the machine tool through the mounting hole 5, the shoulder 2, and the corresponding screws.
[0036] To facilitate processing and ensure the accuracy of tool 13 clamping, the frame 1, shoulder 2, and locking block 8 here adopt an integrated molding structure.
[0037] In addition, there are two clamping stations, which are symmetrically distributed on the frame 1. Each clamping station can be equipped with two cutting tools 13, which are used to process straight holes and inclined holes respectively. The tool holder proposed in this utility model adopts two clamping stations, which can ensure overall symmetry and balance, and can simultaneously meet the installation of four cutting tools 13.
[0038] In summary, the integrated tool holder proposed in this utility model can simultaneously satisfy the tool 13 in machining both inclined and straight holes, thereby improving the efficiency of hole machining and ensuring the positional accuracy of both straight and inclined holes.
