[0033] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0034] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or variations thereof such as "comprises" or "including" etc. will be understood to include the stated element or component, without excluding other elements or other components.

[0035] Embodiment 1

[0036] As Figure 1 shown, a multifunctional detection device includes: a rotating mechanism 10, a detection mechanism 20, and a main shaft 30.

[0037] As Figure 1 shown, the rotating mechanism 10 has a rotation center axis L parallel to the x-axis, and the rotating mechanism 10 is cooperatively installed with the detection mechanism 20. The rotating mechanism 10 is used to drive the detection mechanism 20 to rotate around the rotation center axis L. In this embodiment, the rotating mechanism 10 can drive the detection mechanism 20 to rotate 180° around the rotation center axis L.

[0038] As Figure 1 shown, the rotating mechanism 10 includes a multi-axis indexing plate 11, a tailstock 12 coaxially arranged with the multi-axis indexing plate 11, and a mounting plate 13 disposed between the multi-axis indexing plate 11 and the tailstock 12.

[0039] The multi-axis indexing plate 11 can drive the mounting plate 13 to rotate around the rotation center axis L. The mounting plate 13 is used for clamping products and is also cooperatively installed with the detection mechanism 20. In this embodiment, the multi-axis indexing plate 11 is a four-axis indexing plate. In other embodiments, the multi-axis indexing plate 11 can be an indexing plate with other numbers of axes, as long as it can drive the detection mechanism 20 to rotate 180° around the rotation center axis L.

[0040] In this embodiment, the multi-axis indexing plate 11 can drive the mounting plate 13 to rotate 180° around the rotation center axis L.

[0041] As Figure 1 shown, the rotating mechanism 10 further includes a base 14, and the base 14 is used to fix the multi-axis indexing plate 11 and the tailstock 12. In this embodiment, two bases 14 are provided to respectively fix the multi-axis indexing plate 11 and the tailstock 12. In other embodiments, one base 14 can be provided to fix the multi-axis indexing plate 11 and the tailstock 12.

[0042] As Figure 1 shown, the detection mechanism 20 includes a detection probe 21 and a fixing component 22 for placing the detection probe 21. The fixing component 22 is disposed on one side of the mounting plate 13 and rotates together with the mounting plate 13.

[0043] The detection probe 21 can detect the length of the cutting tool, as well as the wear and breakage of the cutting tool during the machining process. The detection probe 21 can also detect the machining origin, flatness of the product, and the dimensions of the product after machining. The detection probe 21 can also detect the dimensions of the product clamping.

[0044] The multi-axis indexing table 11 drives the mounting plate 13 to rotate 180° around the rotation center axis L, thereby driving the fixing assembly 22 and the detection probe 21 placed on the fixing assembly 22 to rotate 180° around the rotation center axis L.

[0045] As Figure 2 Combined Figure 1 As shown, the fixing assembly 22 includes a base 221 fixedly installed on the mounting plate 13 and a locking assembly fixed on the base 221. The base 221 is used to place the detection probe 21, and the locking assembly is used to fix and release the detection probe 21.

[0046] As Figure 3 , Figure 4 And Figure 2 As shown, the detection probe 21 includes a body 210 and a first annular protrusion 211 and a second annular protrusion 212 provided on the body 210. An installation hole 2211 for placing the detection probe 21 is formed on the base 221, and the installation hole 2211 is a stepped hole. The detection probe 21 passes through the installation hole 2211, so that the bottom surface of the second annular protrusion 212 abuts against the inner horizontal plane 22111 of the installation hole 2211, and the first annular protrusion 211 is fixed by the locking assembly.

[0047] In this embodiment, a groove 2111 is provided on the first annular protrusion 211. The locking assembly includes a cylinder 2221 and a retaining piece 2222. The cylinder 2221 is installed on the base 221, and the cylinder 2221 is used to push the retaining piece 2222 into the groove 2111 to limit the movement of the detection probe 21. The cylinder 2221 is a flexible self-locking cylinder.

[0048] In this embodiment, two sets of locking assemblies are provided and arranged symmetrically, and the number of the limiting grooves 121 corresponds to the number of the locking assemblies. In other embodiments, the number of the locking assemblies can be greater than two and other arrangement methods can be adopted.

[0049] As Figure 4 As shown, a contact member 231 in contact with the detection probe 21 and an elastic member (not shown) connecting the contact member 231 and the installation hole 2211 are installed in the installation hole 2211. One end of the elastic member is connected to the contact member 231, and the other end is connected to the side wall 22112 above the inner horizontal plane 22111 of the installation hole 2211. The contact member 231 can be made of rubber or plastic material. The contact member 231 can be in a hemispherical shape. A plurality of sets of the contact member 231 and the elastic member are provided and distributed in a circular pattern.

[0050] When the detection probe 21 is placed in the placement hole 2211, the bottom of the second annular protrusion 212 presses against the abutting member 231, causing the elastic member to contract. At the same time when the bottom of the second annular protrusion 212 contacts the inner horizontal plane 22111 of the placement hole 2211, the abutting member 231 abuts against the side wall of the detection probe 21 between the first annular protrusion 211 and the second annular protrusion 212 under the action of the elastic member. By providing the abutting member 231 and the elastic member, the placement of the detection probe 21 in the placement hole 2211 is a soft placement, preventing the detection probe 21 from being damaged due to hard contact when placed in the placement hole 2211.

[0051] When the detection probe 21 is placed in the placement hole 2211, the detection end of the detection probe 21 passes through the placement hole 2211 and is exposed on one side of the base 221, and another part of the detection probe 21 is exposed on the other side of the base 221 due to the blockage of the placement hole 2211.

[0052] In the initial state, both the base 221 and the mounting plate 13 are parallel to the horizontal plane. The detection end of the detection probe 21 passing through the placement hole 2211 is located below the base 221, and another part of the detection probe 21 is located above the base 221. As Figure 5 shown, after the multi-axis indexing disk 11 drives the mounting plate 13 to rotate 180° around the rotation center axis L, the detection end of the detection probe 21 passing through the placement hole 2211 is located above the base 221, and another part of the detection probe 21 is located below the base 221. At this time, after rotating the detection probe 21 180° around the rotation center axis L, the tool or product is moved above the detection probe 21 to contact the detection end of the detection probe 21, and finally the tool length and product size are detected through the jump function of the detection probe 21.

[0053] As Figure 1 and Figure 2As shown, the main shaft 30 is used to clamp the tool and the detection probe, and is capable of grasping the detection probe 21 and driving it to move. When the main shaft 30 drives the detection probe 21 to move to the detection mechanism 20, the detection probe 21 is fixed. When the detection probe 21 is needed, the main shaft 30 drives the detection probe 21 to move to the detection mechanism 20. The cylinder 2221 drives the retaining piece 222 to contract, and the main shaft 30 places the detection probe 21 into the placement hole 2211. Then the cylinder 2221 drives the retaining piece 222 to extend to fix the detection probe 21, and the main shaft 30 moves away. The multi-axis indexing disc 11 drives the mounting plate 13 to rotate 180° around the rotation center axis L. At this time, the main shaft 30 can grasp the tool, the product or the product clamping and move it to the safe operation height above the detection probe 21 for detection. When the detection probe 21 is not needed, the multi-axis indexing disc 11 drives the mounting plate 13 to rotate back to 0° around the rotation center axis L. The cylinder 2221 drives the retaining piece 222 to contract, and the main shaft 30 grasps and moves the detection probe 21 away.

[0054] Compared with the traditional manual tool setting, the precision of the present invention can reach 0.003, and the tool setting speed is faster. Compared with the traditional manual tool setting, the fault maintenance operation of the present invention is more convenient. The detection probe 21 covers the functions of a tool setting instrument, and can detect the product clamping, the flatness of the product, the machining origin of the product, the straightness correction of the product, and the dimensions of the product, which saves more costs. Compared with the traditional broken tool detection, the detection precision of the present invention is higher. At the same time, it can detect the tool wear condition, and can accumulate tool use experience by detecting the tightness of the tool wear condition and the product quality condition.

[0056] S10. Move the main shaft 30 above the fixing component 22, place the detection probe 21 clamped by the main shaft 30 on the fixing component 22, and lock the detection probe 21 with the locking component;

[0058] S30. Move the main shaft 30 above the detection probe 21, and make the tip of the tool contact the detection probe 21 to detect the tool length.

[0059] In addition, before S10, the following steps are also included:

[0060] S0. Move the main shaft 30 above the mounting plate 13, and make the detection probe 21 clamped by the main shaft 30 contact the product mounted on the mounting plate 13 to detect the product size before machining.

[0061] Further, after S30, the following steps are further included:

[0062] S40. Move the main shaft 30 above the mounting plate 13, and bring the cutting tool clamped by the main shaft 30 into contact with the product mounted on the mounting plate 13 to process the product;

[0063] S50. Move the main shaft 30 to the tool magazine of the machine tool, deposit the cutting tool into the tool magazine, and the multi-axis indexing disk 11 rotates 180° again;
