Description

Technical Field

[0001] The present invention relates to the field of profiling machine tools, and in particular to a high-precision automatic adjustment profiling metal cutting machine tool. Background Art

[0002] A profiling machine tool refers to a semi-automatic machine tool that controls the movement trajectory of a tool or a workpiece according to a template or a master model for cutting. Its working steps are as follows: First, the master model is clamped on the side of the machine tool, and then a metal cylinder to be cut is clamped on a three-jaw chuck. Then, the position of the tool rest is adjusted to ensure that the contact head on the tool rest abuts against the master model. Subsequently, the entire machine tool drives the tool rest to move automatically, and the contact head continuously slides on the outer wall of the master model, synchronously causing the turning tool to cut out the same shape on the outside of the metal cylinder along the trajectory of the master model. However, the existing profiling machine tools have the following limitations: 1. Only one master model can be installed at a time. Usually, there are many processing batches in the factory at the same time, and the number of processing batches is adjusted in real time according to the sales situation. This leads to frequent manual replacement of the master model during daily cutting processing. The manual replacement time and steps are numerous, which has a great impact on the cutting efficiency and increases the labor intensity. 2. During the daily production process of the master model, the part where the supply contact head abuts needs to be lubricated for a long time to ensure that the friction between the contact head and its outer wall is small and the contact head can slide smoothly. The existing profiling machine tools still require workers to apply lubricating oil, which further increases the labor intensity. Summary of the Invention

[0003] In order to make up for the deficiencies of the existing technology, the purpose of the present invention is to provide a high-precision automatic adjustment profiling metal cutting machine tool that can install multiple master models at the same time, can automatically switch the master models, saves the time for replacing the master models, and can automatically lubricate the master models.

[0004] In order to solve the problems of the existing technology, the technical solution of the present invention is as follows: A high-precision automatic adjustment profiling metal cutting machine tool includes a machine tool body.

A top plate is fixed on the top of the resisting block. A pin is slidably connected to the top plate through a sliding hole. A spring is sleeved on the outer side of the upper end of the pin. One end of the spring is fixed to the outer wall of the pin, and the other end of the spring is fixed to the outer wall of the top plate. A clamping hole is formed in the middle of the profiling die, and the pin is inserted into the clamping hole.

[0008] Preferably, the rotating assembly includes a sprocket wheel fixed to the upper end of the first rotating shaft. One side of the upper end of the bearing frame is rotatably connected to a second rotating shaft through a bearing. A driving wheel is fixed to the lower end of the second rotating shaft. The driving wheel is matched with the sprocket wheel. A motor is fixed to the top of the bearing frame. The upper end of the second rotating shaft is fixed to the output end of the motor.

[0009] Preferably, the coating assembly includes a storage tank fixed to the top of the bearing frame. A terminal conveying pipe is communicated with the discharging end of the storage tank. A nozzle is fixed to the end of the terminal conveying pipe away from the storage tank. A support bar is fixed to the inner wall of the upper end of the bearing frame. The terminal conveying pipe is fixed to the outer wall of the support bar. A brush is fixed to the lower end of the support bar. The nozzle faces the brush, and the bristles of the brush face the bearing plate. The coating assembly further includes a conveying assembly fixed to the top of the bearing frame for conveying the lubricating oil inside the storage tank into the terminal conveying pipeline.

[0010] Preferably, the conveying assembly includes a sleeve fixed to the top of the bearing frame. One end of the sleeve close to the second rotating shaft is open. A starting conveying pipe is fixed to the outer wall of the sleeve away from its open end. The starting conveying pipe away from the sleeve is communicated with the storage tank. A first one-way valve is fixed to the end of the starting conveying pipe close to the storage tank. The end of the sleeve away from the second rotating shaft is communicated with the terminal conveying pipe. A second one-way valve is fixed to the end of the terminal conveying pipe away from the sleeve. A piston is inserted into the sleeve. A push-pull rod is fixed to the outer wall of the piston. The push-pull rod is slidably connected to the sleeve through a sliding hole. One end of the push-pull rod close to the second rotating shaft is rotatably connected to a driving shaft through a bearing. A driving disc is fixed to the upper end of the second rotating shaft. A driving groove is formed in the driving disc, and the driving shaft is inserted into the driving groove.

[0011] Preferably, the coating assembly further includes a receiving box installed at the bottom of the brush. A oil-blocking structure for blocking the lubricating oil bounced off by the bristles of the brush when the profiling die rotates away from the brush is further installed on the outer wall of the brush.

[0012] Preferably, the oil baffle structure includes two cross bars slidably mounted on the outer wall of the lower end of the brush through linear slide rails. The receiving box is fixed to the bottom of the linear slide rails. One end of each of the two cross bars is fixed with a baffle. Longitudinal diversion grooves are equidistantly formed on the side of the baffle close to the bristles. The baffle is located directly above the receiving box. An electric push rod is fixed to the side of the brush close to the cross bar. The extending end of the electric push rod is fixed to the outer wall of one of the cross bars at the upper end. A camera is fixed to the upper end of the support bar.

[0013] Compared with the prior art, the advantages of the present invention are as follows: 1. Since a carrier plate capable of installing six templates is provided and a rotating assembly is installed in cooperation, during daily production, the templates of multiple batches of products currently produced by an enterprise can be simultaneously installed on the carrier plate. When the production demand is adjusted and the model of the product to be produced changes, by driving the rotating assembly to rotate, the corresponding template can be quickly replaced, and then production work can be quickly resumed. Compared with a profiling machine tool that traditionally requires first removing the old template and then installing a new one, the steps and time for template replacement are greatly reduced, the downtime is shortened, thereby improving production efficiency, saving labor costs, and reducing the labor intensity of workers; 2. During the process of switching the template and the template rotates around the axis of the first rotating shaft, the lubricating oil can be automatically and evenly coated on the working part of the template through the provided coating assembly, ensuring that the contact head can smoothly slide on its surface during the subsequent profiling cutting process, and the lubrication work does not require manual operation; 3. The design of the receiving box is used to collect excess lubricating oil to prevent it from dripping onto other parts of the machine tool or the working area, keeping the machine tool clean and the working environment tidy. The oil baffle structure effectively prevents the lubricating oil from being bounced off by the bristles when the template leaves the brush, avoiding the impact of lubricating oil splashing on the environment.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments

[0032] Example 1, please refer to Figures 1 to 8 , this embodiment provides a high-precision automatic-adjusting profiling metal cutting machine tool, including a machine tool body 1. A bearing frame 2 is installed on an outer wall of one side of the machine tool body 1. A bearing disk 3 is rotatably installed on an inner wall of the bearing frame 2. The bearing disk 3 includes a first rotating shaft 301 fixed in the middle thereof. The first rotating shaft 301 is rotatably connected to the bearing frame 2 through a bearing. Six profiling templates 4 are installed on the bearing disk 3 at equal angular intervals. An inner wall of the bearing frame 2 is installed with a rotating assembly 5 for driving the bearing disk 3 to rotate; During the current production process, profiling templates 4 of multiple different product models simultaneously produced by the factory are all installed on the bearing disk 3. When replacing the profiling template 4 according to production requirements, by driving the rotating assembly 5 to rotate, the bearing disk 3 is driven to rotate, so that the corresponding profiling template 4 faces the machine tool body 1. This design greatly improves the replacement efficiency of the profiling template 4 compared with the prior art, reduces the time wasted in replacing the profiling template 4, improves the production efficiency, and greatly saves the labor intensity of workers without frequently disassembling and assembling the profiling template 4; The rotating assembly 5 includes a grooved wheel 51 fixed to the upper end of the first rotating shaft 301. The grooved wheel 51 is a six-equal-part grooved wheel 51. One side of the upper end of the bearing frame 2 is rotatably connected through a bearing to a second rotating shaft 52. A driving wheel 53 is fixed to the lower end of the second rotating shaft 52. The driving wheel 53 is matched with the grooved wheel 51. A motor 54 is fixed to the top of the bearing frame 2. The upper end of the second rotating shaft 52 is fixed to an output end of the motor 54; When it is necessary to switch the profiling template 4, by driving the motor 54 to rotate, the driving wheel 53 is driven to rotate. When the driving wheel 53 rotates one circle, the grooved wheel 51 rotates 60 degrees, so that the profiling template 4 switches to a position. By driving the motor 54 to rotate to drive the grooved wheel 51 to rotate, finally, a corresponding profiling template 4 rotates to a position facing the machine tool body 1; An inner wall of the bearing frame 2 is also installed with a coating assembly 6 for applying lubricating oil to an outer wall of the profiling template 4 during the rotation of the bearing disk 3; The coating assembly 6 includes a storage tank 61 fixed to the top of the bearing frame 2. A terminal conveying pipe 62 is communicated with a discharging end of the storage tank 61. A spray head 63 is fixed to an end of the terminal conveying pipe 62 away from the storage tank 61. A support bar 64 is fixed to an inner wall of the upper end of the bearing frame 2. The terminal conveying pipe 62 is fixed to an outer wall of the support bar 64. A brush 65 is fixed to the lower end of the support bar 64. The spray head 63 faces the brush 65. Bristles 651 of the brush 65 face the bearing disk 3. The coating assembly 6 further includes a conveying assembly 66 fixed to the top of the bearing frame 2 for conveying the lubricating oil inside the storage tank 61 into the terminal conveying pipe 62; When the driving wheel 53 rotates but the groove wheel 51 has not yet rotated, the conveying assembly 66 works in this process so that the lubricating oil in the storage tank 61 enters the terminal conveying pipe 62 and is sprayed onto the bristle 651 of the brush 65 through the nozzle 63. After the spraying is completed, the driving wheel 53 rotates to drive the groove wheel 51 to rotate, so that the backing mold 4 switches its position. When the backing mold 4 rotates and passes through the brush 65, the brush 65 can evenly apply the lubricating oil to the working position of the backing mold 4, so that in the subsequent metal cutting process, the friction between the contact on the tool holder and the outer wall of the backing mold 4 can be greatly reduced, so that the contact can slide along the outer wall of the backing mold 4 more smoothly; By using the brush 65 to apply the lubricating oil, the brush 65 can also brush away impurities on the outside of the support mold 4 while applying the lubricating oil, thereby achieving a cleaning effect. In particular, for the working part of the support mold 4, which has multiple tortuous and curved parts, the brush 65 can well apply the lubricating oil evenly to the surface of the support mold 4. In particular, for uneven surfaces, the brush 65 can penetrate into the gaps to ensure full coverage of the oil. The conveying assembly 66 includes a sleeve 661 fixed to the top of the carrier frame 2, and the end of the sleeve 661 close to the second rotating shaft 52 is open. A starting conveying pipe 662 is fixed to the outer wall of the sleeve 661 away from the open side. The end of the starting conveying pipe 662 away from the sleeve 661 is connected to the storage tank 61. The end of the starting conveying pipe 662 close to the storage tank 61 is fixed with a first non-return valve 663. The end of the sleeve 661 away from the second rotating shaft 52 is connected to the terminal conveying pipe 62. The terminal conveying pipe 663 is fixed to the end of the starting conveying pipe 662 close to the storage tank 61. A second one-way valve 664 is fixed to the end away from the sleeve 661, a piston 665 is inserted into the inner side of the sleeve 661, a push-pull rod 666 is fixed to the outer wall of the piston 665, the push-pull rod 666 is slidably connected to the sleeve 661 through a sliding hole, and the end of the push-pull rod 666 close to the second rotating shaft 52 is rotatably connected to the driving shaft 667 through a bearing, and a driving disk 668 is fixed to the upper end of the second rotating shaft 52, a driving groove 669 is formed on the driving disk 668, and the driving shaft 667 is inserted into the driving groove 669; In the initial stage of the rotation of the driving wheel 53, during the process that it does not drive the grooved wheel 51 to rotate, the driving disc 668 rotates, and through the driving groove 669, it pushes the driving shaft 667, so that the push rod 666 pushes the piston 665 to slide deeper into the inner side of the sleeve 661, and the lubricating oil inside the sleeve 661 is pushed into the terminal delivery pipe 62 and sprayed from the nozzle 63 onto the brush 65. During this process, the first one-way valve 663 is closed and the second one-way valve 664 is opened. After the lubricating oil is filled onto the brush 65, when the driving wheel 53 continues to rotate, it can drive the grooved wheel 51 to rotate. After the grooved wheel 51 rotates 60 degrees and ends, the driving wheel 53 continues to rotate until the driving wheel 53 rotates one full circle. After the grooved wheel 51 is driven to rotate 60 degrees and ends, during the process that the driving wheel 53 continues to rotate, the driving groove 669 on the driving disc 668 pulls the push rod 666 again, so that the push rod 666 resets to the side close to the second rotating shaft 52, driving the piston 665 to slide towards the side close to the open end of the sleeve 661. During this process, the piston 665 sucks the lubricating oil inside the storage tank 61 into the inner side of the sleeve 661. During this process, the first one-way valve 663 is opened and the second one-way valve 664 is closed, thus completing the work of transporting the lubricating oil; Through mechanical linkage, the work of transporting the lubricating oil is stably linked with the rotation work of the profiling template 4, so that the pumping timing of the lubricating oil is stable and accurate, ensuring that the lubricating oil can be filled on time before each rotation of the profiling template 4.

[0033] Embodiment Two. Please refer to Figures 9 to 11 , this embodiment provides a further technical solution based on Embodiment One. The profiling template 4 is installed on the bearing disc 3 through the buckle assembly 7. The buckle assembly 7 includes a resisting block 71 fixed on the bearing disc 3. One side of the profiling template 4 abuts against the resisting block 71. The top of the resisting block 71 is fixed with a top plate 72. A bolt 73 is slidably connected to the top plate 72 through a sliding hole. A spring 74 is sleeved on the outer side of the upper end of the bolt 73. One end of the spring 74 is fixed to the outer wall of the bolt 73, and the other end of the spring 74 is fixed to the outer wall of the top plate 72. A clamping hole 75 is formed in the middle of the profiling template 4, and the bolt 73 is inserted into the clamping hole 75.

[0034] The installation work between the profiling template 4 and the bearing disc 3 is completed through the buckle assembly 7. Compared with the form of using a screw to tighten to complete the installation work of the profiling template 4 in the traditional technology, the time for disassembling and assembling the profiling template 4 is reduced, and the efficiency of disassembling and assembling the profiling template 4 on the bearing disc 3 is greatly improved. When disassembling, by pulling up the bolt 73 upwards, the bolt 73 can be pulled out of the clamping hole 75 to complete the disassembly work of the profiling template 4, and then the profiling template 4 can be taken away. When installing, one side of the profiling template 4 is abutted against the resisting block 71, the clamping hole 75 is aligned with the bolt 73, and the bolt 73 is released. Under the elastic force of the spring 74, the bolt 73 slides down and is inserted into the inner side of the clamping hole 75 to complete the installation work of the profiling template 4.

[0035] Embodiment Three. Please refer toFigures 12 to 16 , this embodiment provides a further technical solution based on Embodiment 1. The coating assembly 6 further includes a receiving box 8 installed at the bottom of the brush 65. When lubricating oil is applied to the brush 65, inevitably, a small amount of lubricating oil will drip along the brush 65, and the dripping lubricating oil is received by the receiving box 8, preventing the lubricating oil from dripping onto the workplace and equipment, ensuring the cleanliness of the workplace and equipment. At the same time, the received lubricating oil can be effectively collected, facilitating recycling and saving resources; A oil-blocking structure 9 for blocking the lubricating oil bounced off by the bristles 651 of the brush 65 when the profiling die 4 rotates away from the brush 65 is also installed on the outer wall of the brush 65; the oil-blocking structure 9 includes two cross bars 91 slidably installed on the outer wall of the lower end of the brush 65 through a linear slide rail 10. The receiving box 8 is fixed to the bottom of the linear slide rail 10. One end of each of the two cross bars 91 is fixed with a baffle 92. Longitudinal diversion grooves 921 are equally spaced on the side of the baffle 92 close to the bristles 651. The baffle 92 is located directly above the receiving box 8. An electric push rod 93 is fixed to the side of the brush 65 close to the cross bar 91. The extending end of the electric push rod 93 is fixed to the outer wall of the upper cross bar 91. A camera 94 is fixed to the upper end of the support bar 64; The rotation direction of the profiling die 4 is as Figure 14 shown in the T direction. During the rotation of the carrier plate 3 by 60 degrees, when the profiling die 4 rotates to the Figure 15 position, that is, when a part of the bristles 651 of the brush 65 is about to separate from the profiling die 4 and rebound, at this time, the position of the profiling die 4 is observed through the camera 94. At the position shown in Fig. 15, the camera 94 transmits the image data to the controller, and the controller controls the electric push rod 93 to contract, causing the baffle 92 to rise. Then the profiling die 4 continues to rotate away from the brush 65. Since there is no longer the obstruction of the profiling die 4, the resilience of the bristles 651 causes the bristles 651 to rebound quickly. The splashing lubricating oil caused by the rebound is blocked by the baffle 92 and will not splash everywhere, and then can slide down on the baffle 92 into the receiving box 8 for collection, ensuring the cleanliness of the production environment and preventing the lubricating oil from splashing everywhere and affecting the environment. After the profiling die 4 is completely separated from the brush 65 and the bristles 651 are fully rebounded, at this time, the electric push rod 93 extends, causing the baffle 92 to descend and reset. Then the profiling die 4 continues to rotate until the carrier plate 3 completes a 60-degree rotation; thus, the effect of receiving the lubricating oil, preventing the lubricating oil from splashing everywhere, and ensuring the cleanliness of the machine tool and the working environment is achieved.
