Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of five-way tool setting gauges, and particularly relates to a high-rigidity five-way tool setting blade fixing structure. Background Technique
[0002] A five-way tool setting gauge is a contact type tool setting gauge used on a machine tool to automatically measure tool parameters. When the tool on the machine tool touches the tool setting blade of the five-way tool setting gauge, a tool setting signal will be generated, thereby judging the length and diameter of the tool. When measuring the diameter, the tool will be rotated to touch the cylindrical side of the tool setting blade for measurement. Since the number of cutting edges of a general machine tool tool is 1 to 4, during the rotation process, the tool setting blade will be continuously impacted. When measuring a tool with a large diameter, the linear velocity of the tool tip will be very large.
[0003] The existing method is based on Figure 1 As shown, when the tool touches from the side direction of the tool setting blade, a large force needs to be provided by the screw to ensure that the tool setting blade does not rotate. In actual products, due to product size problems, it cannot be designed as a large-size structure or use large screws to ensure high rigidity. This causes the tool setting blade to be prone to loosening and cannot effectively avoid the situation of lever-amplified impact force, thereby affecting its normal use.
[0004] In view of the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model
[0005] To achieve the above object, the utility model provides the following technical solution: a high-rigidity five-way tool setting blade fixing structure, including a tool setting gauge, a tool setting blade body, a weak connection block and a flexible connection piece. One end of the tool setting gauge is provided with a sensor connection end, the bottom end of the tool setting blade body is provided with an external thread, the weak connection block includes a sensor connection part and a tool setting blade connection part, an induced fracture connection part is arranged between the sensor connection part and the tool setting blade connection part, and the sensor connection part and the tool setting blade connection part are connected through the induced fracture connection part;
[0006] A first through hole is opened inside the sensor connection part, thread grooves are opened inside both the sensor connection end and the tool setting blade connection part. One end of the weak connection block is tightly connected through a bolt passing through the first through hole of the sensor connection part and the thread groove of the sensor connection end, and the other end of the weak connection block is tightly connected through the external thread at the bottom of the tool setting blade body and the thread groove of the tool setting blade connection part. One end of the flexible connection piece is connected to the sensor connection end, and the other end of the flexible connection piece is connected to the tool setting blade body.
[0007] As a preferred technical solution of the utility model, the thickness of the sensor connection end of the weak connection block is smaller than the thickness of the tool setting blade connection part.

Detailed Embodiments
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model. Embodiment
[0019] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A five-way blade fixing structure with high rigidity, including a tool setter 1, a tool blade body 2, a weak connection block 3, and a flexible connection piece 4. Specifically, one end of the tool setter 1 is equipped with a sensor connection end 5, and the bottom of the tool blade body 2 is provided with an external thread 6. The weak connection block 3, as the core connection component, is composed of a sensor connection part 7 and a tool blade connection part 8, and the connection between them is realized through an induced fracture connection part 9, ensuring that induced fracture can occur under specific circumstances to ensure the stability and safety of the structure.
[0020] Inside the sensor connection part 7, a first through hole 10 is designed to facilitate the penetration and fixation of bolts. At the same time, thread grooves 11 are provided inside both the sensor connection end 5 and the tool blade connection part 8 to facilitate cooperation with bolts to achieve a tight connection. One end of the weak connection block 3 is tightly connected to the sensor connection end 5 of the tool setter 1 by bolts sequentially passing through the first through hole 10 of the sensor connection part 7 and the thread groove 11 of the sensor connection end 5; the other end is firmly connected to the tool blade body 2 by the cooperation of the external thread 6 at the bottom of the tool blade body 2 and the thread groove 11 of the tool blade connection part 8. The flexible connection piece 4, as a connection bridge, has one end connected to the sensor connection end 5 and the other end connected to the tool blade body 2, providing the necessary flexibility and buffering for the entire structure to ensure stability and accuracy in various working states.
[0021] In order to ensure that the connection path of the tool blade body 2 is long enough and to facilitate the connection to the sensor connection end 5 of the tool setter 1, in this embodiment, as a preferred technical solution of the present utility model, the thickness of the sensor connection end 5 of the weak connection block 3 is less than the thickness of the tool blade connection part 8.
[0022] In order to facilitate the connection of both ends of the flexible connecting piece 4, in this embodiment, as a preferred technical solution of the present invention, second through holes 12 are provided at both ends of the flexible connecting piece 4. A pressing block 13 is fixed to the bottom of the blade body 2. One end of the flexible connecting piece 4 is sleeved on the base of the sensor connecting end 5 of the tool setter 1 through the second through hole 12 at one end and is pressed by the sensor connecting portion 7 of the weak connecting block 3. The other end of the flexible connecting piece 4 is sleeved on the outside of the blade body 2 through the second through hole 12 at the other end and is pressed by the pressing block 13 on the blade body 2 against the blade connecting end of the weak connecting block 3.
[0023] In order to ensure the overall structural strength, in this embodiment, as a preferred technical solution of the present invention, the sensor connecting portion 7, the blade connecting portion 8, and the induced fracture connecting portion 9 of the weak connecting block 3 are of an integrally formed structure.
[0024] In summary, by means of the above technical solution of the present invention, the lower end of the blade body 2 is connected to the blade connecting portion 8 at one end of the weak connecting block 3 through the external thread 6. The weak connecting block 3 is then connected and fastened to the sensor connecting end 5 of the tool setter 1 through a bolt. During use, since the connection between the weak connecting block 3 and the sensor connecting end 5 is a set of closely attached surfaces fixed by bolts, loosening will not occur.
[0025] The material of the weak connecting block 3 is selected as a metal with high hardness and good rigidity, and a small-sized induced fracture connecting portion 9 structure is designed in the middle. The fracture force of this small-sized induced fracture connecting portion 9 structure is much smaller than the destructive force that damages the structure of the sensor connecting end 5. When, during use, due to an error of the machine tool or the operator, the tool quickly impacts the blade body 2, the induced fracture connecting portion 9 will directly break. Due to the function of the flexible connecting piece 4, the broken blade body 2 will not be knocked flying, which is convenient for the operator to replace the weak connecting block 3 and reuse it.
[0026] Finally, it should be noted that in the present invention, unless otherwise clearly specified and limited, terms such as "installation", "setting", "connection", "fixation", "rotation connection", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. It can be the communication inside two components or the interaction relationship between two components. Unless otherwise clearly limited, for those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
