However, the prior art requires that after the previous processing step is completed, the tool used in the previous processing step must be removed before the tool required for the next processing step can be installed on the mounting frame. This increases the workload of the relevant personnel and reduces the processing efficiency. Summary of the invention

[0005] In order to facilitate the replacement of cutting tools by relevant personnel, the present application provides a quick-switching cutting tool structure.

[0007] By adopting the above-mentioned technical scheme, compared with the prior art, relevant personnel need to dismantle the tool used in the previous processing step after the previous processing step is completed, and then install the tool required for the next processing step on the mounting frame to realize the replacement of the processing tool. The present application enables a plurality of tools to be set on the rotating disk through the setting of the rotating disk, so that relevant personnel can adjust the type of tool for the part to be processed by rotating the rotating disk, thereby realizing the adjustment of the processing tool. There is no need for relevant personnel to dismantle the old tool and replace it with a new tool in each processing step, which effectively facilitates the replacement of tools by relevant personnel, improves the efficiency of tool replacement, reduces the workload of relevant personnel, and thus improves the processing efficiency as a whole.

[0008] Preferably, an insertion portion is extended from one end of each of the tools, and the insertion portions are inserted in the rotating disk. The rotating disk is also provided with a plurality of insertion slots for the insertion portions to be inserted. The rotating disk is also provided with a plurality of fixing components, and the fixing components correspond one-to-one to the insertion slots, and the fixing components are used to fix the insertion portions inserted in the insertion slots.

[0009] By adopting the above-mentioned technical solution, the detachable installation method of the tool and the setting of the fixed component enable relevant personnel to adapt to the needs of various processing steps by replacing the tool installed on the rotating disk, so that the present application can process a variety of parts, effectively increasing the scope of application and practicality of the present application.

[0010] Preferably, a positioning mechanism is further provided between the rotating disk and the mounting frame, and the positioning mechanism includes a positioning frame, an abutment frame and a reset member. The positioning frames are provided in a plurality and correspond one to one with the insertion grooves and are all provided on the rotating disk. A recessed groove is provided on each of the positioning frames, and the abutment frame is slidably connected to the mounting frame, and one end of the abutment frame abuts against the inner wall of one of the recessed grooves, and the reset member is used for the abutment frame to continuously abut against the inner wall of the corresponding recessed groove.

[0011] By adopting the above technical solution, the positioning mechanism is set up so that when the tool used for processing needs to be adjusted so that the rotating disk rotates, the abutment frame can continue to abut against the inner wall of the rotating disk under the elastic force of the reset member. When the abutment frame rotates to the corresponding position with the rotating disk, the abutment frame collides with the inner wall of the recessed groove on the corresponding positioning frame under the elastic force of the reset member, and is inserted into the recessed groove, so that the tool corresponding to the positioning frame is in the working position, and there is no need for relevant personnel to repeatedly adjust the position of the corresponding tool, thereby facilitating the positioning of the tool by relevant personnel and effectively reducing the probability of poor processing quality due to the offset of the tool and the working position.

[0012] Preferably, the positioning mechanism also includes a plurality of identification components, and the identification components correspond to the positioning frames one by one. Each of the identification components includes an identification frame and a linkage member. Each of the positioning frames and the identification frame are slidably connected to the rotating disk. Each of the positioning frames is located in the corresponding insertion groove and on the sliding path of the corresponding insertion part, and the sliding direction is the insertion direction of the corresponding insertion part. Each of the identification frames is located on the sliding path of the corresponding positioning frame, and each of the positioning frames drives the corresponding identification frame to slide through the corresponding linkage member to disengage from the sliding path of the corresponding positioning frame.

[0013] By adopting the above technical solution, the identification component is set so that when the tool is not inserted in the insertion slot, the identification frame is located on the displacement path of the abutment frame when it is in the released state. At this time, the identification frame replaces the positioning frame and abuts against the abutment frame, so that the abutment frame is still in an unreleased state, so that when the relevant personnel drives the rotating disk to rotate, the abutment frame can jump over the abutment frame in the insertion slot where the tool is not installed, and abut against the abutment frame in the insertion slot where the next tool is installed for positioning, thereby facilitating the relevant personnel to replace different tools and increasing the efficiency of tool replacement.

[0015] By adopting the above technical solution, the linkage frame is set up so that during the process of inserting the tool in the insertion frame, the insertion part on the tool can gradually abut against the positioning frame and push the positioning frame to slide. The sliding of the positioning frame drives the connecting frame to move, thereby causing the identification frame to slide and gradually break away from the sliding path of the positioning frame, so that the positioning frame replaces the original identification frame and is located on the displacement path of the abutment frame when released, thereby realizing the linkage between the positioning frame and the identification frame, which effectively facilitates the operation of relevant personnel.

[0016] Preferably, each of the identification components further includes a return spring, each of the return springs is located on the sliding path of the corresponding identification frame, one end of each of the return springs abuts against the corresponding identification frame, and the other end abuts against the inner wall of the rotating disk.

[0017] By adopting the above technical solution and setting the reset spring, when the insertion part gradually disengages from the insertion groove, the identification frame can gradually return to its initial position under the elastic force of the reset spring, and drive the positioning frame to gradually return to its initial position through the linkage frame, thereby realizing the reset of the identification frame and the positioning frame, so that the identification frame is again located on the displacement path of the abutment frame when released.

[0018] Preferably, a fixing groove is provided on the side wall of each of the insertion parts, and the fixing components include a fixing frame and an elastic member, the fixing frame is slidably connected to the rotating disk, a fixing part is provided on the fixing frame, the fixing part is inserted in the fixing groove, and the elastic member is used for allowing the fixing part to be continuously inserted in the fixing groove.

[0019] By adopting the above technical solution and specifically arranging the fixing assembly, when the fixing groove on the insertion part corresponds to the fixing part, the fixing frame can slide under the drive of the elastic member, and the fixing part is gradually inserted into the fixing groove, thereby locking the insertion part and effectively facilitating the operation of relevant personnel.

[0020] Preferably, each of the insertion portions is provided with a guide surface on one end of the insertion groove.

[0021] By adopting the above technical solution and setting the guide surface on the insertion part, during the process of the insertion part being inserted into the insertion groove, the guide groove on the insertion part can gradually abut against the fixing part and push the fixing part to slide, thereby achieving the giving way of the insertion part. When the fixing groove on the insertion part corresponds to the fixing part, the fixing part is inserted into the fixing groove again to achieve the fixation of the insertion part, which effectively ensures the smooth operation of the present application and facilitates the operation of relevant personnel.

[0022] Preferably, the locking mechanism includes a rotating frame and a locking frame, the locking frame is located in the mounting frame and is slidably connected to the mounting frame, one end of the locking frame has a prism portion extending outward from the mounting frame, the prism portion is inserted in the rotating disk, the other end of the locking frame is sleeved on one end of the rotating frame and is threadedly connected to the rotating frame, the rotating frame is located in the mounting frame and is rotatably connected to the mounting frame.

[0023] By adopting the above technical solution and the specific setting of the locking mechanism, when the rotating frame rotates, the rotating frame can drive the locking frame connected to its own thread to slide, so that the locking frame gradually approaches the rotating disk, and finally the prism part on the locking frame is inserted into the rotating disk, thereby locking the rotating disk, which effectively facilitates the operation of relevant personnel; at the same time, the existence of the prism part enables the rotating disk to still correspond to the prism part after rotating a certain angle, so that the rotating disk after rotation can continue to be locked by the prism part, effectively ensuring the normal use of the present application.

[0024] Preferably, one end of the rotating frame away from the locking frame extends out of the mounting frame and is provided with a rotating handle.

[0025] By adopting the above technical solution and setting the rotating handle, relevant personnel can drive the rotating frame to rotate by holding the rotating handle, thereby driving the rotating frame, effectively facilitating the operation of relevant personnel and increasing the efficiency of relevant personnel in replacing tools.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The setting of the rotating disk enables a number of tools to be set on the rotating disk, so that the relevant personnel can adjust the type of tool to be used for processing the part by rotating the rotating disk, thereby realizing the adjustment of the processing tool. The relevant personnel do not need to remove the old tool and replace it with a new one in each processing step, which effectively facilitates the replacement of the tool by the relevant personnel, improves the efficiency of tool replacement, reduces the workload of the relevant personnel, and thus improves the processing efficiency as a whole; 2. The positioning mechanism is arranged so that when the tool for processing needs to be adjusted so that the rotating disk rotates, the abutment frame can continuously abut against the inner wall of the rotating disk under the elastic force of the reset member.

A rotating disk 2 is provided on the mounting frame 1, and the rotating disk 2 is rotatably connected to the mounting frame 1, and the rotation axis of the rotating disk 2 is inclined to the installation direction of the mounting frame 1. A plurality of tools 3 are provided on the rotating disk 2, and the plurality of tools 3 are arranged along the circumference of the axis of the rotating disk 2. In the embodiment of the present application, the number of tools 3 on the rotating disk 2 can be set to six, and the six tools 3 are arranged at equal angles along the circumference of the axis of the rotating disk 2. A locking mechanism 4 for locking the rotating disk 2 is also provided on the mounting frame 1.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The mounting frame 1 is provided with a mounting portion 11 on one end away from the rotating disk 2. The mounting portion 11 is formed integrally with the mounting frame 1 and is used to be inserted into the lathe so as to be installed with the lathe. The other end of the mounting frame 1 is provided with a protrusion, and the rotating disk 2 is sleeved on the protrusion on the mounting frame 1 and is rotatably connected to the mounting frame 1 through a bearing. One side of the rotating disk 2 is provided with a concave shape and forms a cavity to match the protrusion on the mounting frame 1. The protrusion on the mounting frame 1 is located in the cavity of the rotating disk 2.

[0037] Reference Figure 2 and Figure 4The locking mechanism 4 includes a rotating frame 41 and a locking frame 42. A rotating handle 43 is provided at one end of the rotating frame 41. The rotating handle 43 is sleeved on the rotating frame 41 and fixedly connected to the rotating frame 41 to facilitate the user to drive the rotating frame 41 to rotate. The side wall of the rotating handle 43 is in contact with the outer wall of the mounting frame 1. The outer wall of the mounting frame 1 on the side of the rotating handle 43 is gradually thickened, so that when the rotating handle 43 rotates to the thickened outer wall, the rotating handle 43 is locked by friction. In other embodiments, a structure for locking the rotating handle 43 may also be provided on the mounting frame 1.

[0038] Reference Figure 2 and Figure 4 , the other end of the rotating frame 41 extends from the end of the mounting frame 1 away from the rotating disk 2, extends into the mounting frame 1, and is rotatably connected to the mounting frame 1 through a bearing. One end of the locking frame 42 is sleeved on the end of the rotating frame 41 extending into the mounting frame 1, and is threadedly connected to the rotating frame 41, and an internal thread is provided on the end of the rotating frame 41. A prism portion 421 extends from the other end of the locking frame 42, and the prism portion 421 and the locking frame 42 are integrally formed. In the embodiment of the present application, the cross-section of the prism portion 421 is a regular hexagon, and each side of the prism portion 421 corresponds to the tool 3 to accommodate the adjustment of the tool 3 when the rotating disk 2 rotates.

[0039] Reference Figure 3 and Figure 4 A locking groove 21 is also provided on the inner wall of the rotating disk 2. In the embodiment of the present application, the cross section of the locking groove 21 is a regular hexagon and is adapted to the prism portion 421. The prism portion 421 is inserted into the locking groove 21 at one end away from the locking frame 42 body to lock the rotating disk 2.

[0040] Reference Figure 2 , Figure 3 and Figure 4 In the initial state, that is, when the rotating disk 2 is not locked with the mounting frame 1, the rotating handle 43 is on the side away from the thicker outer wall of the mounting frame 1, and the prism portion 421 on the locking frame 42 is not inserted into the locking groove 21. When it is necessary to lock the rotating disk 2, after adjusting the angle of the rotating disk 2, the rotating handle 43 is rotated so that the rotating handle 43 rotates toward the side close to the thicker outer wall. At this time, the rotating handle 43 drives the rotating frame 41 to rotate together, so that the rotating frame 41 drives the locking frame 42 threadedly connected to itself to slide, so that the prism portion 421 on the locking frame 42 gradually approaches the locking groove 21, and is finally inserted into the locking groove 21, so as to achieve the locking between the rotating disk 2 and the mounting frame 1. At this time, the side wall of the rotating handle 43 is tightly attached to the thicker outer wall of the mounting frame 1, and the locking is achieved by friction.

[0041] Reference Figure 1, an insertion portion 31 extends from one end of each tool 3, and the insertion portion 31 is fixedly connected to the tool 3 body. The rotating disk 2 is also provided with a plurality of insertion slots 5 for the insertion portions 31 to be inserted. In the embodiment of the present application, the number of the insertion slots 5 is set to six, and they correspond one to one with the tools 3. The plurality of insertion slots 5 are arranged at equal angles along the circumference of the axis of the rotating disk 2, and correspond to the sides of the prism portion 421 of the locking frame 42. Each insertion portion 31 is inserted into the corresponding insertion slot 5, and is slidably connected to the inner wall of the corresponding insertion slot 5.

[0042] Reference Figure 1 and Figure 5 Each insertion portion 31 is located at one end of the insertion slot 5, and a guide surface is provided to guide the insertion portion 31, so as to facilitate the user to install the insertion portion 31. A fixing groove 311 is provided on the side wall of each insertion portion 31. A plurality of fixing components 6 are also provided in the rotating disk 2. In the embodiment of the present application, the number of the fixing components 6 is set to six, and they correspond one to one to the insertion slots 5.

[0043] Reference Figure 3 and Figure 5 Each fixing assembly 6 includes a fixing frame 61 and an elastic member 62. Each fixing frame 61 is slidably connected to the rotating disk 2. The sliding direction of each fixing frame 61 is perpendicular to the insertion direction of the corresponding insertion portion 31. The interior of each fixing frame 61 is hollow to allow the corresponding insertion portion 31 to pass through. Each fixing frame 61 is provided with a fixing portion 611, and each fixing portion 611 is inserted into the corresponding fixing groove 311 to lock the insertion portion 31.

[0044] Reference Figure 3 and Figure 5 In the embodiment of the present application, the elastic member 62 is configured as a pressure spring, each of which is sleeved on the fixing frame 61, and one end of each pressure spring abuts against the outer wall of the corresponding fixing frame 61, and the other end of each pressure spring abuts against the inner wall of the rotating disk 2. When the fixing portion 611 abuts against the inner wall of the fixing groove 311, the pressure spring is in a compressed state, and when the fixing portion 611 gradually separates from the fixing groove 311, the pressure spring continues to be compressed.

[0045] Reference Figure 3 and Figure 5 A pressing portion 612 is extended from one end of each fixing frame 61 away from the fixing portion 611 in a direction away from the fixing portion 611. The pressing portion 612 extends out of the rotating disk 2 and is slidably connected to the inner wall of the rotating disk 2 so that when the user presses the pressing portion 612, the fixing frame 61 body is driven to slide together.

[0046] Reference Figure 1 and Figure 5In the initial state, that is, when the insertion portion 31 is not in contact with the fixing portion 611, the fixing portion 611 is located on the displacement path of the insertion portion 31. When the insertion portion 31 is gradually inserted into the insertion groove 5, the guide surface on the insertion portion 31 gradually abuts against the fixing portion 611, thereby pushing the fixing portion 611 to slide, so that the fixing frame 61 makes way for the insertion portion 31, and the elastic member 62 continues to be compressed. Then, the insertion portion 31 continues to slide, and at this time the fixing portion 611 abuts against the outer wall of the insertion portion 31. When the insertion groove 5 corresponds to the fixing portion 611, the fixing portion 611 slides under the action of the elastic member 62 and is inserted into the insertion groove 5 to lock the insertion portion 31.

[0047] Reference Figure 1 , Figure 4 and Figure 5 A positioning mechanism 7 is also provided between the rotating disk 2 and the mounting frame 1. The positioning mechanism 7 includes a positioning frame 71, an abutting frame 72 and a reset member 73. A plurality of positioning frames 71 are provided. In the embodiment of the present application, six positioning frames 71 are provided and correspond to the insertion slots 5 one by one. Each insertion slot 5 is connected to a chamber on the rotating disk 2. Each positioning frame 71 is located in the corresponding insertion slot 5 and is slidably connected to the inner wall of the insertion slot 5. The sliding direction of each positioning frame 71 is the same as the sliding direction of the corresponding insertion portion 31 and is located on the sliding path of the corresponding insertion portion 31.

[0048] Reference Figure 3 and Figure 5 , a concave groove 711 is provided on a side wall of each positioning frame 71 away from the insertion portion 31, and the concave groove 711 is a hemispherical groove. The positioning mechanism 7 also includes a plurality of identification components 74. In the embodiment of the present application, the number of identification components 74 is six, and they correspond to the abutment frames 72 one by one. Each identification component 74 includes an identification frame 741, a linkage member 742 and a return spring 743, and each identification frame 741 is slidably connected to the rotating disk 2.

[0049] Reference Figure 5 Each linkage member 742 includes a linkage frame 7421. In the embodiment of the present application, the number of linkage frames 7421 in each linkage member 742 is set to two to increase the stability of the transmission. The linkage frames 7421 in each linkage member 742 are respectively located on both sides of the corresponding positioning frame 71. One end of each linkage frame 7421 is rotatably connected to the corresponding positioning frame 71 through a pin shaft, and the other end of each linkage frame 7421 is rotatably connected to the corresponding identification frame 741 through a pin shaft.

[0050] Reference Figure 5Each linkage frame 7421 is tilted to facilitate the positioning frame 71 to drive the identification frame 741. Each reset spring 743 is located on the sliding path of the corresponding identification frame 741 and is located on the side of the corresponding identification frame 741 away from the positioning frame 71. One end of each reset spring 743 abuts against the identification frame 741, and the other end abuts against the inner wall of the rotating disk 2 to reset the identification frame 741.

[0051] Reference Figure 1 and Figure 5 In the initial state, that is, when the insertion portion 31 is not inserted into the insertion slot 5, the positioning frame 71 is located at the end of its own sliding path farthest from the mounting frame 1, and the identification frame 741 is located on the sliding path corresponding to the positioning frame 71, and the return spring 743 is in a compressed state. When the insertion portion 31 is inserted into the insertion slot 5 and contacts the positioning frame 71, the insertion portion 31 pushes the positioning frame 71 to slide, so that the positioning frame 71 gradually approaches the mounting frame 1.

[0052] Reference Figure 5 During this process, the positioning frame 71 drives the identification frame 741 to slide away from the positioning frame 71 through the linkage frame 7421, thereby giving way to the positioning frame 71. During this process, the reset spring 743 continues to be compressed, thereby storing elastic potential energy. When the insertion portion 31 moves to the specified position, that is, when the fixing frame 61 locks the insertion portion 31, the positioning frame 71 replaces the original position of the identification frame 741. At this time, the recessed groove 711 on the positioning frame 71 is close to the outer wall of the rotating disk 2, so as to be close to the mounting frame 1.

[0053] Reference Figure 5 and Figure 6 , the abutment frame 72 is located at a position directly opposite to the mounting portion 11, one end of the abutment frame 72 is located in the mounting frame 1 and is slidably connected to the inner wall of the mounting frame 1, and the other end of the abutment frame 72 extends out of the mounting frame 1 and is hemispherical. In the embodiment of the present application, the reset member 73 is a pressure spring, which is located on the side of the abutment frame 72 away from the rotating disk 2, and one end of the pressure spring abuts against one end of the abutment frame 72 located in the mounting frame 1, and the other end abuts against the inner wall of the mounting frame 1. When the recessed groove 711 approaches the mounting frame 1, the abutment frame 72 abuts against the inner wall of the recessed groove 711 under the elastic force of the reset member 73, and at this time the reset member 73 is in a compressed state.

[0054] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6In the initial state, that is, when the insertion portion 31 is not inserted into the insertion groove 5, the side wall of the identification frame 741 is located in the chamber of the rotating disk 2, and the abutment frame 72 abuts against the side wall of the identification frame 741 or the side wall of the upper chamber of the rotating disk 2. When the insertion portion 31 pushes the positioning frame 71 to slide and replaces the identification frame 741, the rotating disk 2 is rotated so that one of its recessed grooves 711 corresponds to the abutment frame 72. Under the elastic force of the reset member 73, the abutment frame 72 moves into the recessed groove 711 and abuts against the inner wall of the recessed groove 711, making a sound and hindering the rotation of the rotating disk 2, thereby positioning the rotating disk 2 and the tool 3. At this time, the user perceives the obstruction and hears the sound, and understands that the current position is the correct angle position of the tool 3.

[0055] Reference Figure 5 and Figure 6 When the user wants to continue to rotate the rotating disk 2, the user rotates the rotating disk 2 with force so that the inner wall of the recessed groove 711 abuts against the end wall of the abutting frame 72, thereby pushing the abutting frame 72 to gradually separate from the recessed groove 711 and continue to replace the tool 3.

[0056] The implementation principle of a fast-switching tool structure of the embodiment of the present application is as follows: when the tool 3 to be used needs to be replaced, the rotating handle 43 is rotated so that the rotating handle 43 rotates toward the side away from the thicker outer wall. At this time, the rotating handle 43 drives the rotating frame 41 to rotate, so that the prism portion 421 on the locking frame 42 gradually disengages from the locking groove 21, thereby unlocking the rotating disk 2 and the mounting frame 1. Then, the rotating disk 2 is rotated, and when the tool 3 to be used corresponds to the mounting portion 11, and when the abutment frame 72 abuts against the inner wall of the recessed groove 711 under the elastic force of the reset member 73, thereby hindering the rotation of the rotating disk 2, so that when the user notices it, the rotating handle 43 is turned back to lock the rotating disk 2 and the mounting frame 1, and the replacement is completed.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
