Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision cutting tool technology, and in particular to a special retainer for replacing cutting blades. Background Technology
[0002] In existing CNC machine tools, small modular heads are used. When it is necessary to replace the cutting tools on the modular head, the modular head must be removed first, and then the cutting tools on the modular head must be removed to replace the new cutting tools. However, due to the relatively large size of the modular head, removing and installing cutting tools is quite difficult.
[0003] Therefore, it is necessary to design a special retainer for replacing blades to solve the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a special retainer for replacing blades, which can facilitate the replacement of blades and has strong versatility.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A blade replacement retainer includes a columnar retainer body, with retaining positions at both ends and the middle of the retainer body; each of the three retaining positions is provided with a mounting hole for inserting the connecting end of the module head and a locking member for locking the connecting end of the module head in the mounting hole.
[0007] Furthermore, a positioning groove is provided on the fixing position located in the middle of the fixing body, and the mounting hole is opened on the inner bottom surface of the positioning groove, and the central axis of the mounting hole is offset relative to the central axis of the fixing body.
[0008] Furthermore, a reinforcing rib is provided at one end of the positioning groove near the mounting hole.
[0009] Furthermore, a side positioning part for laterally positioning the module head is provided on the fixing position located at one end of the fixing body.
[0010] Furthermore, the opening of the mounting hole is flared.
[0011] Furthermore, the locking element is a locking screw screwed into the body of the fixture, and one end of the locking screw can enter into the corresponding mounting hole and be screwed into the connecting end of the module head located in the mounting hole.
[0012] Furthermore, a placement plane is provided on the side of the fixture body, and the placement plane is disposed opposite to the fixing position located in the middle of the fixture body.
[0013] Furthermore, a pressing surface is provided between two adjacent fixing positions on the fixing body, and the two pressing surfaces are parallel to the placement plane.
[0014] The beneficial effects of this utility model are as follows: This utility model provides a special fixing device for replacing blades, which fixes the module head on the fixing position of the fixing device body, thereby making it easy to replace the blade on the module head. In addition, the fixing device body is provided with three different fixing positions, which can be used to fix different module heads, making it highly versatile. Attached Figure Description
[0015] Figure 1 This is a structural schematic diagram of a blade replacement fixture provided by this utility model. Detailed Implementation
[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0017] like Figure 1 As shown, a blade replacement retainer includes a columnar retainer body 1, with retaining positions 2 at both ends and the middle of the retainer body 1; each of the three retaining positions 2 is provided with a mounting hole 3 for inserting the connecting end of the module head and a locking member for locking the connecting end of the module head in the mounting hole 3.
[0018] Specifically, in this embodiment, a placement plane 11 is provided on the side of the fixture body 1, which is disposed opposite to the fixing position 2 located in the middle of the fixture body 1. A pressing surface 12 is provided between two adjacent fixing positions 2 on the fixture body 1, and the two pressing surfaces 12 are parallel to the placement plane 11.
[0019] In use, the fixture body 1 can be stably placed by placing the flat surface 11; by applying downward pressing force to the two pressing surfaces 12, the fixture body 1 can be fixed, so as to make it easier to replace the blade on the module head.
[0020] In this embodiment, a positioning groove 4 is provided on the fixing position 2 located in the middle of the fixing body 1. The mounting hole 3 is opened on the inner bottom surface of the positioning groove 4, and the central axis of the mounting hole 3 is offset relative to the central axis of the fixing body 1. With this structure, the locking connection between the fixing body 1 and the locking member can have high structural strength, ensuring that the locking member can lock the connection end of the module head in the mounting hole 3 well.
[0021] Furthermore, a reinforcing rib 6 is provided at one end of the positioning groove 4 near the mounting hole 3 to further enhance the structural strength of the fixture body 1 in the positioning groove 4.
[0022] In this embodiment, a side positioning part 5 for laterally positioning the module head is provided on the fixing position 2 at one end of the fixing body 1, so that the connecting end of the module head can be accurately installed in the mounting hole 3.
[0023] In this embodiment, the opening of the mounting hole 3 is flared to facilitate the smooth entry and exit of the module head connection end into and out of the mounting hole 3, reducing the difficulty of disassembly and assembly.
[0024] As a preferred embodiment, the locking component is a locking screw screwed into the fixture body 1. One end of the locking screw can enter the corresponding mounting hole 3 and be screwed into the connection end of the module head located in the mounting hole 3.
[0025] This utility model discloses a special tool changer. In use, the fixing positions 2 at both ends of the tool body 1 are used to install a grooving tool module head and a turning module head, respectively, while the fixing position 2 in the middle of the tool body 1 is used to install a Y-axis module head. After fixing the module head to the corresponding fixing position 2, the tool on the module head is removed, a new tool is replaced, and then fixed. Finally, the module head with the replaced tool is removed from the tool body 1. This special tool changer allows for convenient replacement of tool heads and is highly versatile.
[0026] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
