TECHNICAL FIELD

[0001] The utility model relates to the field of machining, especially a device for automatic tool breaking test. BACKGROUND

[0002] As the core equipment in modern manufacturing industry, machining centers play an important role in complex workpiece machining with high precision and high efficiency. During the design and manufacturing process of machining centers, the spindle as its core component directly affects the machining precision and efficiency. Before leaving the factory, the spindle needs to undergo strict tool breaking test to ensure the normal operation and reliability of its internal structure. Tool breaking test involves hundreds of times of connection and disconnection of the spindle and the test tool handle to simulate the actual tool changing operation.

[0003] In the prior art, tool breaking test mainly relies on manual operation to position and fix the test tool handle. This operation method not only has low efficiency, but also is prone to cause the tool handle to fall off after disconnection due to human factors, resulting in test interruption and equipment damage. In addition, the repeatability and accuracy of manual operation are difficult to guarantee, which is particularly prominent in machining center test with high precision requirements.

[0004] With the development of industrial automation technology, the market demand for improving the efficiency and safety of machining center test is increasing. The tooling equipment for automatic positioning and fixing of the test tool handle becomes the key to solving the above problems. This equipment can reduce human errors, improve the continuity and reliability of the test, and reduce labor intensity and cost. Therefore, developing a tooling capable of automatically positioning and fixing the test tool handle is of great significance to improve the efficiency and safety of machining center spindle test. SUMMARY

[0010] As a preferred scheme, the positioning pin is of cylindrical structure, and the diameter of the positioning pin is smaller than the diameter of the inner hole of the test tool holder.

[0011] As a preferred scheme, the centers of the positioning pin, the test tool holder, the main shaft of the machining center and the positioning hole of the main support are located on the same horizontal line.

[0012] The beneficial effects of the utility model are as follows:

[0013] Based on the deficiencies of the prior art, the utility model provides a device for automatic tool testing, which has the following technical effects through optimized structure design:

[0014] Firstly, the utility model realizes automatic positioning and fixing of the test tool holder through the positioning hole in the center of the main support and the positioning pin. The cylindrical structure of the positioning pin and the design that the diameter of the positioning pin is smaller than the diameter of the inner hole of the test tool holder ensure that the tool holder can be accurately positioned and fixed directly above the end face of the main shaft of the machining center.

[0023] Embodiment one,

[0024] In order to more clearly describe the specific structural composition of the device for automatic tool breaking test, the drawings of the present application are combined with the drawings of the present application. Figure 1 -Appendix Figure 2 Description of the present embodiment:

[0025] The embodiment is a device for automatic tool breaking test, which is arranged at one end of a machining center spindle 4. The automatic tool breaking test device comprises a main support 1, which is located above the end face of the machining center spindle 4 and is connected with the spindle flange 5 on the circumferential surface of the spindle through the support frame 2 fixed at both ends. The center of the main support 1 is provided with a positioning hole, which corresponds to the center of the end face of the machining center spindle 4 to ensure accuracy. In addition, a positioning pin 3 for fixing the test tool is arranged between the end face of the machining center spindle 4 and the main support 1. The positioning pin 3 is installed through the positioning hole in the main support 1 and is further fixed by bolts, which ensures that the test tool holder 6 can be stably positioned and clamped.

[0026] Further, in order to adapt to machining center spindles 4 of different diameters, the two ends of the main support 1 are provided with a plurality of adjusting hole positions, which allow the support frame 2 to adjust the position according to actual needs, so that the device has good universality and adaptability. The support frame 2 adopts an L-shaped structure, and the end closer to the right angle bend is fixed on the bottom of the spindle flange 5 by bolts, and the other end is connected with the main support 1 by bolts. This split design simplifies the adaptation process for different types of machining centers, without the need to customize different tooling for each spindle size, thereby saving time and cost.

[0027] In the embodiment, the main support 1 is in a long strip shape and is made of a material that can be elastically deformed. This not only enhances the durability of the device, but also provides the necessary flexibility during testing, which helps to protect the test equipment from impact damage.

[0028] In the embodiment, the positioning pin 3 adopts a cylindrical structure, and its diameter is smaller than that of the inner hole of the test tool holder 6, which ensures that the tool holder can be smoothly installed on the positioning pin 3, and the center of the positioning hole of the machining center spindle 4 and the main support 1 are located on the same horizontal line, realizing the high-precision coaxiality requirement.

[0029] Specific operation steps:

[0030] The first step, the staff installs the support frame 2 on the spindle flange 5 on the circumferential surface of the machining center spindle 4, and selects the appropriate adjusting hole position according to the diameter of the machining center spindle 4, and uses bolts to stably fix the support frame 2 on the spindle 4;

[0031] The second step, the staff places the long strip-shaped main support 1 on the support frame 2, ensuring that it is located above the end face of the machining center spindle 4. Then the main support 1 is firmly fixed on the support frame 2 through screws or bolts, and the position is adjusted to align the positioning hole in the center of the main support 1 with the center of the end face of the machining center spindle 4;

[0032] The third step, the worker inserts the cylindrical positioning pin 3 into the inner hole of the test handle 6. Then, place the test handle 6 with the positioning pin 3 above the positioning hole of the main support 1, make sure that the positioning pin 3 corresponds to the mounting hole, and then use the bolt to fix the positioning pin 3 on the main support 1 through the positioning hole. At this time, it should be checked whether the positioning pin 3, the test handle 6, the machining center spindle 4 and the positioning hole of the main support 1 are located on the same horizontal line.

[0033] The fourth step, the worker starts the equipment to start the tool breaking test. During the test, the machining center spindle 4 and the test handle 6 are constantly disconnected and clamped again. The test handle 6 is accurately positioned and firmly fixed by the combined action of the positioning pin 3 and the main support 1, and the test handle 6 will not fall off.

[0034] Through this design, the operator can simultaneously carry out batch machining center spindle tool breaking test, which significantly improves the test efficiency. Due to the improvement of test efficiency, the production cycle is shortened, which further improves the production efficiency and reduces the production cost per unit product. In addition, due to the reduction of dependence on manual operation, a large amount of manpower and material resources is saved, the damage and test interruption of the equipment caused by human error is reduced, and the cost of maintenance and retest is reduced.

[0035] Example two,

[0036] In order to more clearly describe the specific structure of the device for automatic tool breaking test, combined with the attached Figure 1 -attached Figure 2 This embodiment describes a device for automatic tool breaking test, which is arranged at one end of the machining center spindle 4. The automatic tool breaking test device includes a main support 1, which is located above the end face of the machining center spindle 4 and is connected with the spindle flange 5 on the circumferential surface of the machining center spindle 4 through the support frame 2 fixed at both ends. The center of the main support 1 is provided with a positioning hole, which corresponds to the center of the end face of the machining center spindle 4 to ensure accuracy. In addition, a positioning pin 3 for fixing the test tool is arranged between the end face of the machining center spindle 4 and the main support 1. The positioning pin 3 is installed through the positioning hole on the main support 1 and is further fixed by the bolt, which ensures that the test handle 6 can be stably positioned and clamped.

[0037] Further, the present embodiment is adapted to machining center spindles 4 of different diameters, and the main support 1 is provided with a plurality of adjusting hole positions at both ends, which allow the support frame 2 to be adjusted in position as needed, so that the device has good versatility and adaptability. The support frame 2 has an L-shaped structure, and the end closer to the right angle bend is bolted to the bottom of the spindle flange 5, and the other end is bolted to the main support 1. This split design simplifies the adaptation process for different types of machining centers, eliminating the need to customize different tooling for each spindle size, thereby saving time and cost.

[0038] In the present embodiment, the main support 1 is a long strip-shaped structure and is made of a material that can undergo elastic deformation. This not only enhances the durability of the device, but also provides the necessary flexibility during testing, helping to protect the test equipment from impact damage.

[0039] Unlike the first embodiment, in the present embodiment, the positioning pin 3 is specially designed to reduce the load on the bolts used to secure it to the main support 1. Specifically, the positioning pin 3 has a hollow cylindrical structure. This hollow design not only reduces the weight of the positioning pin 3 itself, thereby reducing the stress on the bolts securing it, but also enhances the durability and stability of the device without affecting its functionality.

[0040] Further, the diameter of the positioning pin 3 in the present embodiment is smaller than the diameter of the inner hole of the test handle 6, ensuring that the handle can be smoothly installed onto the positioning pin 3, and that the centers of the handle, the positioning pin 3, the machining center spindle 4, and the positioning hole of the main support 1 are all on the same horizontal line, achieving high-precision coaxiality requirements.

[0041] Specific operation steps:

[0042] The first step, the staff installs the support frame 2 on the spindle flange 5 on the circumference of the machining center spindle 4, and selects the appropriate adjusting hole position according to the diameter of the machining center spindle 4, and uses bolts to securely fix the support frame 2 on the spindle 4;

[0043] The second step, the staff places the long strip-shaped structure of the main support 1 on the support frame 2, ensuring that it is directly above the end face of the machining center spindle 4. Then the main support 1 is securely fixed on the support frame 2 by screws or bolts, while adjusting the position to align the center of the positioning hole of the main support 1 with the center of the end face of the machining center spindle 4;

[0044] The third step, the worker inserts the cylindrical positioning pin 3 into the inner hole of the test handle 6. Then, the test handle 6 with the positioning pin 3 is placed above the positioning hole of the main support 1, ensuring that the positioning pin 3 corresponds to the mounting hole, and the worker uses the bolt to fix the positioning pin 3 on the main support 1 through the positioning hole. At this time, it should be checked whether the positioning pin 3, the test handle 6, the machining center spindle 4, and the positioning hole of the main support 1 are located on the same horizontal line.

[0045] The fourth step, the worker starts the equipment to start the tool breaking test. During the test, the machining center spindle 4 and the test handle 6 are constantly disconnected and clamped again. The test handle 6 is accurately positioned and firmly fixed by the combined action of the positioning pin 3 and the main support 1, and the test handle 6 will not fall off.

[0046] Through this design, the operator can simultaneously perform batch machining center spindle tool breaking tests, significantly improving test efficiency. Due to the improvement in test efficiency, the production cycle is shortened, further improving production efficiency and reducing the production cost per unit product. In addition, due to the reduction in reliance on manual operation, a large amount of manpower and resources is saved, equipment damage and test interruptions caused by human error are reduced, and maintenance and retesting costs are reduced.

[0047] Example Three,

[0048] The embodiment is an automatic tool breaking test device arranged at one end of a machining center spindle 4. The automatic tool breaking test device includes a main support 1 located directly above the end face of the machining center spindle 4 and connected to the spindle flange 5 on the circumference of the main shaft through a support frame 2. The center of the main support 1 is provided with a positioning hole corresponding to the center of the end face of the machining center spindle 4 to ensure accuracy. In addition, a positioning pin 3 for fixing the test tool is arranged between the end face of the machining center spindle 4 and the main support 1. The positioning pin 3 is installed through the positioning hole on the main support 1 and further fixed by a bolt, ensuring that the test handle 6 can be stably positioned and clamped.

[0049] Unlike the first embodiment, the third embodiment includes three support frames 2, and the main support 1 is shaped to include the same number of branches as the support frames 2. One end of the branch is connected to the main support 1, and the other end is connected to one end of the remaining branch to form a main support 1 similar in structure to a "Y".

[0050] A large number of support frames 2 can provide additional support force when necessary, making the entire device more stable, especially suitable for larger or heavier test tools.

[0051] It should be noted that although the utility model is described through the above embodiments, the utility model can also have other various embodiments.
