[0049] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0051] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0052] In order to solve the technical problem that the existing loading method of machine tools is not convenient for automatic loading and positioning, the present application provides a feeding mechanism and a machine tool, which can realize automatic loading and positioning through the mutual cooperation of the feeding module 1, the material transfer module 2, the clamping module 3 and the positioning module 4, thereby improving the loading efficiency and reducing the labor intensity of workers.

[0053] See also Figures 1 to 11, the first aspect of the embodiment of the present application provides a feeding mechanism, including a feeding module 1, a moving module 2, a clamping module 3 and a positioning module 4 arranged in sequence, the moving module 2 is arranged between the feeding module 1 and the clamping module 3, the feeding module 1 has a loading position, which can be used to receive or place the raw materials to be loaded, the clamping module 3 has a clamping position, and the clamping position is arranged opposite to the loading position; the moving module 2 includes a moving component 21 movably arranged corresponding to the loading position, the moving component 21 moves between the loading position and the clamping position, so that the moving component 21 can drive the raw materials in the loading position to move to the clamping position, and the moving component 21 can be reset after the loading is completed, thereby realizing automatic loading. At the same time, in order to locate the position of the raw materials to be processed, a positioning component 41 corresponding to the movable setting of the clamping position is provided on the positioning module 4. The positioning component 41 is used to confirm whether the raw materials are in the correct position in the clamping position. After the positioning is completed, the raw materials can be stably clamped by the clamping module 3 for subsequent automatic processing, thereby realizing accurate positioning of the raw materials and automatic loading, which can improve loading efficiency and reduce the labor intensity of workers.

[0054] It should be noted that the feed mechanism in this application can be used to automatically load raw materials such as bar stock 7 and block stock. A chute assembly 12 is provided at the loading station. The chute in the chute assembly 12 is a V-shaped or rectangular groove that is used to position the raw material within the loading station. In the embodiment of this application, bar stock 7 is used as the raw material to be loaded, and the chute in the chute assembly 12 is a V-shaped groove to prevent the bar stock 7 from rolling within the chute assembly 12.

[0055] In some embodiments of this application, please refer to Figure 5 and Figure 6 The bar feeding assembly 11 includes a plurality of fixed step plates 112 and movable step plates 113 arranged at intervals. The movable step plates 113 can be lifted up and down, and the loading position is located at the top of the fixed step plates 112. Specifically, the movable step plates 113 are connected to the lifting assembly located inside the base 116. The movable step plates 113 are lifted by the lifting assembly, and the plurality of movable step plates 113 lift the bar 7 until the step surface of the movable step plates 113 is flush with the upper step surface of the fixed step plates 112. The bar 7 will roll along the step surface of the movable step plates 113 to the step surface of the fixed step plates 112, and then the movable step plates 113 will descend, and the bar 7 will stay on the upper step surface of the fixed step plates 112. Through multiple lifting and lowering, the bar 7 can be gradually raised, and then fall from the top of the fixed step plates 112 into the loading chute assembly 12, and wait to be driven by the material moving assembly 21 in the loading position.

[0056] In some embodiments of this application, please refer to Figure 3 and Figure 5The bar feeder assembly 11 further includes a plurality of relatively slidable side plates 111, which are disposed on fixed step plates 112. This allows the length of the bar 7 in the bar feeder assembly 11 to be limited by the relatively slidable side plates 111. Specifically, the bar feeder assembly 11 includes a first side plate 111a and a second side plate 111b. The first side plate 111a is fixedly connected to the fixed step plates 112 on both sides of the bar feeder assembly 11. The second side plate 111b is disposed between the two first side plates 111a, and the first side plate 111a and the second side plate 111b are disposed parallel to each other. The second side plate 111b is connected to the first side plates 111a on both sides through the sliding rod assembly 114. The second side plate 111b can slide along the length direction of the sliding rod assembly 114, thereby adjusting the distance between the second side plate 111b and the first side plate 111a. The rod 7 is placed between the first side plate 111a and the second side plate 111b, and the axis of the rod 7 is perpendicular to the first side plate 111a, thereby limiting the length of the rod 7.

[0057] In some embodiments of this application, please refer to Figure 5 The bar feed assembly 11 further includes a bottom plate 115 connected to the side plates. The side plates 111 and bottom plate 115 are perpendicular to each other and connected. The bottom plate 115 is tilted, and the bottom end of the bottom plate 115 abuts the bottom end of the fixed step plate 112. The bottom plate 115, the side plates 111, and the fixed step plate 112 enclose a silo for storing the bar stock 7. The tilted bottom plate 115 and the abutment of the bottom end of the bottom plate 115 against the bottom end of the fixed step plate 112 allow the bar stock 7 to accumulate at the bottom of the fixed step plate 112, facilitating the step-by-step lifting of the bar stock 7 at the bottom by the movable step plate 113.

[0058] It should be noted that in the above embodiment, the material moving assembly 21 can load the material by pushing the tail end of the bar 7 or clamping the tail end of the bar 7. In some preferred embodiments of the present application, in order to simplify the structural setting of the material moving assembly 21, loading is performed by pushing the tail end of the bar 7.

[0059] In some embodiments of the present application, the material moving module 2 includes a first sliding component 22, which is connected to the material moving component 21. The sliding direction of the first sliding component 22 is parallel to the length direction of the loading trough component 12. Within the sliding stroke of the material moving component 21, the material moving component 21 moves back and forth at the loading position, and the rod material 7 in the loading trough component 12 can be pushed into the clamping module 3 through the material moving component 21.

[0060] In some embodiments of the present application, the sliding member of the first sliding assembly 22 is connected to the material moving assembly 21, which can drive the material moving assembly 21 to slide along the length direction of the loading chute assembly 12, thereby realizing automatic loading of the rod material 7.

[0061] In some specific embodiments of the present application, in order to make the structure simple and convenient, the material moving component 21 can be a pin or a block. The specific structure of the material moving component 21 is not limited in the present application. It is only necessary to push the raw materials in the loading trough component 12 to the clamping position through the material moving component 21.

[0062] In some embodiments of the present application, the material transfer module 2 further includes a sensor signal-connected to the first sliding assembly 22. The sensor is arranged corresponding to the loading position and is used to detect whether the bar 7 is present in the loading chute assembly 12. Specifically, the sensor is a fiber optic sensor, which is arranged above the loading chute assembly 12. When the bar 7 falls from the top of the fixed step plate 112 to the loading chute assembly 12, the fiber optic sensor can detect whether the bar 7 is in place and send an action signal to the first sliding assembly 22.

[0063] In existing CNC grinding machines, most use the traditional front-side loading method of the chuck assembly 82, which loads and unloads the bar 7 through the clamping jaws. Since the clamping jaws need to be in a material tray with a clear gap to smoothly pick up the bar 7, this loading method cannot provide a sufficiently large storage space for the bar 7 within the limited machine tool space. In contrast, by disposing the bar feeding assembly 11 outside the machine tool and loading the bar 7 one by one through the material transfer module 2, a sufficiently large storage space for the bar 7 is formed outside the machine tool while preventing the bar 7 storage space from affecting the internal structure of the machine tool.

[0064] In some embodiments of this application, please refer to Figure 4 、 Figure 8 and Figure 9 The clamping module 3 includes a first clamping component 31 and a second clamping component 32 located at both ends of the clamping position. The first clamping component 31 has a first clamping opening 311, and the second clamping component 32 has a second clamping opening 321. The first clamping opening 311 and the second clamping opening 321 are coaxially arranged, and the first clamping opening 311 and the second clamping opening 321 are connected to the two ends of the clamping position to form a hollow loading channel, which is convenient for the rod material 7 to be inserted into the first clamping opening 311 and the second clamping opening 321 in sequence during loading.

[0065] It should be noted that the diameters of the first clamping opening 311 and the second clamping opening 321 can be changed to facilitate the clamping of the rod 7 after the rod 7 is smoothly inserted. Specifically, the first clamping assembly 31 and the second clamping assembly 32 both include a clamping cylinder, which is used to drive the first clamping opening 311 or the second clamping opening 321 to change diameter.

[0066] In some embodiments of this application, please refer to Figure 3 and Figure 4The first clamping port 311 is located at the end of the clamping position close to the loading position, and the second clamping port 321 is located at the end of the clamping position away from the loading position. The bar material 7 first enters the hollow loading channel of the clamping module 3 through the first clamping port 311, and then extends out from the second clamping port 321. The rear side loading is realized through the cooperation of the feeding module 1, the material moving module 2 and the clamping module 3, thereby solving the problem that the existing front side loading method is inefficient and cannot provide a large-capacity bar material 7 storage space in a limited space.

[0067] The positioning module 4 is movably arranged on the side of the second clamping opening 321 away from the clamping position, and is used to position the length of the bar material 7 extending out of the second clamping opening 321, such as Figure 9 The positioning assembly 41 can be a touch switch or a proximity switch. When the front end of the bar 7 touches or approaches the positioning assembly 41, the positioning assembly 41 transmits a signal to the control center of the feeding mechanism, causing the material moving assembly 21 to stop pushing the material. At the same time, the first clamping assembly 31 and the second clamping assembly 32 clamp the bar 7.

[0068] In the above embodiment, in order to prevent the positioning assembly 41 from interfering with the processing of the bar 7, the positioning assembly 41 is movably arranged at the front end of the second clamping opening 321. Specifically, the positioning module 4 includes a second sliding assembly 42 and a rotating assembly 43, and the rotating assembly 43 is connected to the positioning assembly 41 and the second sliding assembly 42, respectively. The horizontal distance between the positioning assembly 41 and the second clamping opening 321 can be adjusted by the second sliding assembly 42, so as to achieve the positioning of the extended length of the bar 7. The rotating assembly 43 is connected to the second sliding assembly 42, and can drive the positioning assembly 41 to rotate relative to the second clamping opening 321. After the positioning is completed, the positioning assembly 41 can be rotated to avoid the positioning assembly 41 from obstructing the processing of the bar 7.

[0069] In some preferred embodiments of this application, please refer to Figure 9 The second sliding assembly 42 includes a guide rod 421 and a slider 422. The guide rod 421 is fixedly connected to the clamping module 3, and the axial direction of the guide rod 421 is parallel to the axial direction of the bar 7. The slider 422 is slidably arranged on the guide rod 421 and can be used to drive the rotating assembly 43 and the positioning assembly 41 to slide along the axial direction of the guide rod 421. The rotating assembly 43 includes a swing arm 431 and a rotary drive member 432. The rotary drive member 432 is fixedly connected to the slider 422 of the second sliding assembly 42. One end of the swing arm 431 is rotatably arranged on the rotary drive member 432, and the other end of the swing arm 431 is connected to the positioning assembly 41, and is used to drive the positioning assembly 41 to rotate in a vertical plane to avoid processing the bar 7.

[0070] It should be noted that in order to ensure the accuracy of positioning, the slider 422 of the second sliding component 42 has a self-locking function to prevent the slider 422 from driving the rotating component 43 and the positioning component 41 to move during the positioning process, resulting in inaccurate length of the positioned rod 7.

[0071] The second aspect of the embodiment of the present application provides a machine tool, including a machine tool body 5 and the feeding mechanism described in the above embodiment, wherein the feeding mechanism is arranged on the machine tool body 5, wherein the clamping module 3 of the feeding mechanism is movably arranged on the machine tool body 5, and the position of the rod material 7 inside the machine tool can be adjusted by the clamping module 3 to facilitate loading and processing.

[0072] In some preferred embodiments of the present application, the feeding module 1 and the material transfer module 2 in the feeding mechanism are arranged on the outside of the machine tool body 5, and the clamping module 3 is arranged on the inside of the machine tool body 5, such as Figure 2 As shown, the space occupied by the material feeding module 1 and the material moving module 2 inside the machine tool can be reduced, so that the size of the raw material storage of the material feeding module 1 is not limited by the volume of the machine tool.

[0073] In order to facilitate the smooth transportation of the bar material 7 from the loading position to the clamping position, as shown in the figure Figure 7 As shown, a hollow feed port assembly 55 is provided on the machine tool body 5, and the feed port assembly 55 is provided between the feeding module 1 and the clamping module 3, wherein the feeding module 1 is located outside the machine tool and the clamping module 3 is located inside the machine tool, so that the rod material 7 can enter the inside of the machine tool from the outside through the feed port assembly 55 to realize rear side loading.

[0074] When the bar feed assembly 11 is mounted on the outside of the machine tool body 5, the machine tool body 5 includes a mounting base assembly 54, such as Figure 3 The base 116 of the bar feed assembly 11 is connected to the mounting base assembly 54. Specifically, a bar-shaped hole is provided on the base 116 or the mounting base assembly 54 to facilitate adjustment of the mounting position of the bar feed assembly 11 on the mounting base assembly 54.

[0075] In some embodiments of this application, please refer to Figure 2 、 Figure 4 and Figure 10 The machine tool also includes a processing mechanism 6, which includes a processing component 61 that is movably arranged corresponding to the clamping position. The processing component 61 can move relative to the bar material 7 on the clamping position, so that the bar material 7 can be cut or ground.

[0076] As a specific embodiment of the present application, the processing mechanism 6 also includes a rotating drive component 62 connected to the processing component 61. The rotating drive component 62 can drive the processing component 61 to rotate. The processing component 61 is provided with a grinding wheel. Through the relative movement of the clamping module 3 and the processing mechanism 6, the grinding processing of the rod material 7 can be achieved.

[0077] In the prior art, the rotating shaft assembly 81 of the workpiece axis mechanism 8 or the rotary shaft of the machining mechanism 6 is rotatably mounted within the machine tool body 5 without any other restraining structure. This can easily cause the top of the rotating shaft of the workpiece axis mechanism 8 or the machining mechanism 6 to wobble during rotation, resulting in poor rigidity. This can easily lead to vibration in the machining mechanism 6 or the workpiece axis mechanism 8, thereby affecting the machining accuracy of the workpiece.

[0078] In order to solve the above problem, in some embodiments of the present application, both ends of the processing mechanism 6 are rotatably connected to the machine tool body 5, such as Figure 10 and Figure 11 Specifically, the upper and lower ends of the processing mechanism 6 are rotatably connected to the frame assembly 56 of the machine tool body 5 via the first rotating shaft assembly 64 and the second rotating shaft assembly 67, respectively, so that the upper and lower ends of the processing mechanism 6 are constrained. When the processing mechanism 6 processes the bar material 7 set on the clamping module 3, the frame assembly 56 constrains the upper and lower ends of the processing mechanism 6, which can improve the rigidity of the processing mechanism 6.

[0079] Specifically, the first rotating shaft assembly 64 includes an upper bearing, a bearing seat, and an upper connecting shaft, and is used to achieve a rotational connection with the top of the frame assembly 56. The second rotating shaft assembly 67 includes a turntable connecting plate and a turntable motor, which drives the first rotating shaft assembly 64 and the second rotating shaft assembly 67 to rotate synchronously.

[0080] In some preferred embodiments of the present application, to ensure the rigidity of the processing mechanism 6 when it rotates via the first rotating shaft assembly 64 and the second rotating shaft assembly 67, the frame assembly 56 is preferably made of a material with high rigidity and low density, thereby ensuring the rotational accuracy of the processing mechanism 6 when it rotates about the vertical direction. As a specific embodiment of the present application, the frame assembly 56 is a marble frame.

[0081] In some embodiments of this application, please refer to Figure 11 The processing mechanism 6 further includes a connecting frame assembly 63, a first connecting arm assembly 65, and a second connecting arm assembly 66. The first connecting arm assembly 65 and the second connecting arm assembly 66 are connected to both ends of the connecting frame assembly 63, forming a vertical cradle mounting frame for mounting the rotary drive assembly 62 and the processing assembly 61. Because the upper and lower ends of the vertical cradle mounting frame are constrained by the frame assembly 56, it can effectively resist the grinding force of the machine tool and significantly reduce the vibration of the first connecting arm assembly 65 and the second connecting arm assembly 66 caused by the grinding force. Therefore, it can effectively improve product precision in processes with large grinding volumes.

[0082] The first connecting arm assembly 65 and the second connecting arm assembly 66 are used to make the processing assembly 61 deviate from the first rotating shaft assembly 64 and the second rotating shaft assembly 67 and the rotation axis, so that a larger processing space can be reserved.

[0083] In some embodiments of the present application, the machine tool body 5 also includes a third sliding component 51, a fourth sliding component 52 and a fifth sliding component 53 whose sliding directions are perpendicular to each other. The third sliding component 51, the fourth sliding component 52 and the fifth sliding component 53 drive the clamping module 3 and the processing component 61 to move relative to each other, so that the machine tool has multi-axis freedom, which is convenient for high-precision processing.

[0084] It should be noted that the sliding directions of the third sliding assembly 51, the fourth sliding assembly 52, and the fifth sliding assembly 53 correspond to the X, Y, and Z directions of the machine tool, respectively. One or more of the third sliding assembly 51, the fourth sliding assembly 52, and the fifth sliding assembly 53 are connected to the clamping module 3, while the other sliding assemblies not connected to the clamping module 3 are connected to the processing assembly 61 of the processing mechanism 6.

The processing assembly 61 and the rotary drive assembly 62 are mounted on the sliding member of the fifth sliding assembly 53. This allows the processing assembly 61 to move in the Z direction, facilitating alignment processing with the clamping module 3.

[0086] In some embodiments of this application, please refer to Figures 1 to 11 , the processing method of the machine tool of this application is as follows:

[0087] Step 1: Adjust the distance between the first side plate 111a and the second side plate 111b, place multiple bars 7 in the bar feeding assembly 11, and use the bar feeding assembly 11 to gradually lift the bars 7 until the top bar 7 falls into the chute assembly 12;

[0088] Step 2: The material transfer module 2 detects the bar material 7 falling into the chute assembly 12 through the optical fiber sensor, drives the first sliding assembly 22, and causes the first sliding assembly 22 to drive the material transfer assembly 21, and the material transfer assembly 21 pushes the bar material 7 in the chute assembly 12 to the clamping position;

[0089] Step 3: During the loading process, when the front end of the bar 7 touches the positioning assembly 41, the material moving assembly 21 stops, the first clamping assembly 31 and the second clamping assembly 32 clamp the bar 7, and the rotating assembly 43 drives the positioning assembly 41 to rotate to avoid the bar 7 and the processing mechanism 6;

[0090] Step 4: Adjust the relative position between the clamping module 3 and the processing assembly 61 under the action of the third sliding assembly 51, the fourth sliding assembly 52, the fifth sliding assembly 53, the first rotating shaft assembly 64 and the second rotating shaft assembly 67; drive the rod 7 and the processing assembly 61 to rotate respectively through the driving assembly 33 and the rotating driving assembly 62 to realize multi-axis precision grinding.
