[0018] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0019] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0020] The following will be combined with specific embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] See Figures 1 to 5As shown, the structure of the utility model is: a tool changing clamp of an engraving and milling machine, comprising a fixed base 2; a positioning sleeve 3, mounted at the bottom of the fixed base 2 and provided with a tapered hole matching the tool handle 6; a clamping jaw assembly 4, arranged above the tapered hole, for grabbing the tool handle 6; a driving assembly 1, mounted on the fixed base 2, for driving the clamping jaw assembly 4, specifically, the driving assembly 1 drives the clamping jaw assembly 4 to open, the tool handle 6 is inserted into the tapered hole, and then the driving assembly 1 drives the clamping jaw assembly 4 to clamp the end of the tool handle 6, which is then lifted and transported to the designated position by the robotic arm in the tool magazine system.

[0022] like Figure 1 As shown, a sensor 5 is installed on the positioning sleeve 3 . Specifically, the sensor 5 is used to detect whether there is a tool handle 6 in the positioning sleeve 3 .

[0023] like Figures 2 to 5 As shown, the clamping jaw assembly 4 includes a push block 401, and the two sides of the push block 401 are slidably connected with the inclined blocks 402, and the clamping jaws 403 are installed on the inclined blocks 402. Specifically, grooves are provided on the two surfaces of the push block 401 that contact the inclined blocks 402, and springs are provided in the grooves that abut the push block 401 and the inclined blocks 402. The driving assembly 1 drives the push block 401 to move upward, pushing the inclined blocks 402 to move to both sides, and the spring is compressed, so that the clamping jaws 403 open and release the knife handle 6; the driving assembly 1 drives the push block 401 to move downward, driving the inclined blocks 402 to move closer to the middle, so that the clamping jaws 403 close and clamp the knife handle 6, and at the same time the elastic force of the spring pushes the inclined block 402.

[0024] like Figure 4 、 Figure 5 As shown, a tenon 404 is provided on the push block 401, and a slot 405 that matches the tenon 404 is provided on the inclined block 402. Specifically, the tenon 404 is slidably engaged with the inclined block 402 to drive the clamping jaw 403 to clamp or release.

[0025] like Figure 5 As shown, an arc-shaped notch is provided at the end of the clamping jaw 403. Specifically, the arc-shaped notch facilitates clamping the end of the shank 6.

[0026] Furthermore, the driving component 1 is a cylinder.

[0027] During specific use, the robotic arm in the tool magazine system drives the positioning sleeve 3 to the position of the tool handle 6, and sleeves the tool handle 6 through the tapered hole. Then the cylinder drives the push block 401 to move downward, driving the inclined block 402 to move closer to the middle, so that the clamping jaws 403 close and clamp the tool handle 6. At the same time, the elastic force of the spring pushes the inclined block 402 to prevent the inclined block 402 from moving downward with the push block 401. Then the sensor 5 will detect whether the tool handle 6 is successfully clamped. Then the robotic arm in the tool magazine system lifts the tool handle 6 and transports it to the designated position. Then the cylinder drives the push block 401 to move upward, pushing the inclined block 402 to move to both sides, and compressing the spring to open the clamping jaws 403 to release the tool handle 6.

[0028] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
