Description

Technical Field

[0001] The invention belongs to the technical field of modular machine tools, and relates to a modular machine tool and a processing method for producing circular elastic bodies for floor scale sensors. Background Art

[0002] In the manufacturing process of floor scale sensors, circular elastomers are key components, and their production accuracy and efficiency directly affect the overall performance and manufacturing cost of the sensors. Currently, the traditional production method of circular elastomers often relies on multiple independent machine tools to operate. These machine tools are responsible for different processes such as milling, conveying, cutting, flipping and drilling. However, this production method has many disadvantages.

[0003] On the one hand, since each process is carried out on different machine tools, raw materials need to be frequently transferred between different machine tools, which not only increases the consumption of manpower and time, but also easily leads to positioning deviation of raw materials during the transfer process, thereby affecting the processing accuracy. Especially in key processes such as milling and drilling, a small positioning error may lead to product scrapping and waste of resources.

[0004] On the other hand, the independent operation of each machine tool in the traditional production method makes it difficult to achieve efficient coordination of the production process. For example, after cutting is completed, the material needs to be manually transferred to the flipping mechanism for flipping, and then sent to the drilling machine for drilling. During this process, the machine tool is idle for a long time and the production efficiency is low. At the same time, manual operation also increases safety risks. Improper operation may lead to work-related accidents.

[0005] Therefore, we proposed a combined machine tool and processing method for producing circular elastic bodies for floor scale sensors to solve the above-mentioned problems. Summary of the Invention

[0049] 1. The modular machine tool for producing circular elastic bodies for floor scale sensors disclosed in the present invention realizes rapid milling of raw materials into squares by arranging a connection frame with four milling heads on one side of a vertical milling machine. The four milling heads are symmetrically distributed in pairs and can process the raw materials from four directions simultaneously, greatly shortening the milling time and improving production efficiency. At the same time, since the milling process is precisely controlled by the No. II motor, the square materials processed are ensured to have accurate dimensions and a smooth surface, providing a good foundation for subsequent processing.

[0050] 2. The modular machine tool for producing circular elastic bodies for floor scale sensors disclosed in the present invention has an electromagnet block No. 1 slidingly arranged inside the conveyor frame, which is driven by motor No. 1 to accurately and stably push the raw materials to move. The rectangular hole opened on the top of the conveyor frame and the guide wheels arranged inside the conveyor frame not only provide a good guiding effect for the raw materials, but also reduce the friction and resistance of the raw materials during the movement, ensuring smooth and efficient transportation of the raw materials, allowing the raw materials to reach various processing areas quickly and accurately, further improving production efficiency.

[0051] 3. The combined machine tool for producing circular elastic bodies for floor scale sensors disclosed in the present invention has a close cooperation between the cutting mechanism and the flipping mechanism, which realizes the rapid slitting and flipping of square materials. The cutting mechanism is driven by the No. II electric push rod to quickly push the cutting blade toward the material to achieve efficient cutting, while the flipping mechanism is driven by the No. V motor to drive the No. III rotating ring and the clamping assembly to rotate, flipping the slit material to a suitable angle for subsequent processing. This not only improves the efficiency of cutting and flipping, but also ensures stability and safety during the processing.

[0052] 4. The combined machine tool for producing circular elastomers for floor scale sensors disclosed in the present invention, the coordinated work of the drilling mechanism and the flipping mechanism realizes comprehensive drilling of the material surface. The drilling mechanism is driven by electric push rod No. 1 to adjust the height of the lifting plate, and then adjust the position of the drill bit to realize the feeding action. At the same time, motor No. 4 drives the two sliding blocks to move through the bidirectional screw, further adjusting the horizontal position of the drill bit, so that the drill bit can accurately align with each surface of the material for drilling, and the drill bit can remain stable during the drilling process, ensuring the accuracy and quality of the drilling. In addition, when it is necessary to process the side grooves of the material, the matching design of the rotating rod and the fixed block enables the milling cutter to quickly approach the side of the material to achieve efficient processing.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0068] like Figures 1-9 As shown, a combined machine tool for producing circular elastomers for floor scale sensors includes a vertical milling machine 1. A support platform 11 is bolted to the top of the vertical milling machine 1. A clamp 12 is installed on the support platform 11 to fix the raw material during the processing. On one side of the vertical milling machine 1, a support frame 2 is fixed by welding or bolting. A connecting frame 5 is fixed to the top of the support frame 2. Four No. 1 fixing seats 51 are bolted inside the connecting frame 5. These four fixing seats are symmetrically distributed in pairs and are located around the processing area. A No. 2 motor 52 is bolted to one side of each No. 1 fixing seat 51. The output end of the No. 2 motor 52 extends into the interior of the No. 1 fixing seat 51 and is fixedly connected to the milling head 53. When the No. 2 motor 52 is started, the milling head 53 rotates accordingly, and can mill the raw material into a square shape.

[0069] A support frame 3, numbered II, is mounted on one side of the vertical milling machine 1. A conveyor frame 4 is fixedly mounted on top of the support frame 3. Two rectangular holes 41 are defined in the top of the conveyor frame 4. Multiple guide wheels 42 are rotatably mounted in each of these holes via bearings. These guide wheels 42 guide the material during movement, ensuring smooth movement. Furthermore, a rectangular hole 43 is defined in the top of the conveyor frame 4. A nut block is rotatably mounted in each of these holes via bearings. An electromagnet block 44 is fixedly attached to the nut block. A motor 46 is bolted to one side of the conveyor frame 4. The output end of the motor 46 is fixedly connected to a screw 45. When the motor 46 is activated, the screw 45 rotates, driving the nut block to slide within the rectangular holes 43. This in turn drives the electromagnet 44, pushing the material along the conveyor frame 4, thus enabling material feeding.

[0070] The cutting mechanism is mounted on one side of the vertical milling machine 1 and specifically includes two guide rods 17, each of which is slidably mounted on the side of the vertical milling machine 1. One end of each guide rod 17 is fixedly connected to a common fixed seat 19. A motor push rod 18, numbered II, is also fixedly mounted on one side of the vertical milling machine 1. The output end of the motor push rod 18 is fixedly connected to the fixed seat 19. A cutting disc 21 is connected to one side of the fixed seat 19 via a rotating shaft. A motor 20, numbered VI, is bolted to one side of the motor push rod 18. The output end of the motor 20 is in driving connection with the rotating shaft of the cutting disc 21. When the squared material needs to be cut, the motor push rod 18 pushes the fixed seat 19 to move, bringing the cutting disc 21 closer to the material. Simultaneously, the motor 20 is activated, driving the cutting disc 21 to rotate and cut the material. A hinged protective cover can be installed on the outside of the vertical milling machine 1, which can be opened during operation.

[0071] The flipping mechanism is mounted on the support platform 11 and includes a No. II connecting seat 13 bolted to the top of the support platform 11. A No. III rotating ring 14 is rotatably mounted in the No. II connecting seat 13 via a bearing. A No. V motor 15 is bolted to one side of the No. II connecting seat 13, and the output end of the No. V motor 15 is in transmission connection with the No. III rotating ring 14. A clamping assembly for securing the product is disposed in the No. III rotating ring 14. The clamping assembly includes three cavities 26 defined within the No. III rotating ring 14, each of which has two No. III guide rods 27 slidably mounted therein. The upper and lower sets of No. III guide rods 27 are each fixedly connected to a No. I clamping block 24 for clamping the product, near one end thereof. The other set of No. III guide rods 27 is fixedly connected to a No. II clamping block 25 on one side thereof. The clamping block 25 (No. II) cooperates with the groove on the side of the product to position the product. The outer wall of the guide rod 27 (No. III) is equipped with a spring 28. The two ends of the spring 28 respectively contact the inner wall of one side of the cavity 26 and the other end of the guide rod 27 (No. III) through the spring 28 seat. When the cut material needs to be turned over, the motor 15 (No. V) starts, driving the rotating ring 14 (No. III) to rotate, thereby driving the clamping assembly and the material to turn together.

[0072] The drilling mechanism 6 is mounted on the support platform 11 and includes a connecting plate 67 positioned above the support platform 11. Multiple No. 1 guide rods 68 are fixedly connected to the top of the connecting plate 67. The outer walls of the multiple No. 1 guide rods 68 are slidably sleeved with a common lifting plate 69. A fixed platform 610 is welded to the top of the lifting plate 69, and a No. 3 motor 66 is bolted to the top of the fixed platform 610. Two sliding blocks 612 are slidably mounted within the lifting plate 69. Two universal couplings 613 are rotatably mounted on the sides of the sliding blocks 612 and the fixed platform 610, respectively, via bearings. The two universal couplings 613 on the same side are connected by an expansion joint 614. A drill bit 64 is fixedly mounted within the lower universal coupling 613, while the two upper universal couplings 613 are connected via a synchronous pulley and a synchronous belt drive. The output end of motor III 66 is fixedly connected to the corresponding universal joint 613. A bidirectional screw 615 is rotatably mounted within the fixed platform 610 via a bearing. Two sliding blocks 612 are threaded onto the bidirectional screw 615. Motor IV 616 is bolted to one side of the fixed platform 610, its output end fixedly connected to the bidirectional screw 615. A motor I push rod 617 is fixedly mounted through the top of the lifting plate 69, its output end fixedly connected to the connecting plate 67. When drilling is required, push rod I 617 lowers the lifting plate 69, bringing the drill bit 64 closer to the material. Simultaneously, motor III 66 is activated, driving the drill bit 64 to rotate and drill the material. When motor IV 616 is activated, the bidirectional screw 615 rotates, driving the two sliding blocks 612 closer or further away from each other, thereby adjusting the position of the drill bit 64 to achieve drilling at different locations.

[0073] Furthermore, a rotating bar 618 is rotatably mounted on the outer wall of the outer universal joint 613 via a bearing. A rotating rod 619 is rotatably mounted on the top of the rotating bar 618 via a bearing. A milling cutter 65, used for machining the side grooves, is fixedly mounted on the bottom of the rotating rod 619. The rotating rod 619 is connected to the corresponding universal joint 613 via a synchronous pulley and belt drive, or via a gear train. A stopper 620 is fixedly mounted on the bottom of the lifting plate 69 to limit the position of the rotating bar 618. A tension spring 621 is connected between the rotating bar 618 and the lifting plate 69. A support rod 22 is fixedly mounted on one side of the No. 2 fixing seat 19, and a fixed block 23, which cooperates with the rotating rod 619, is fixedly mounted on the other end of the support rod 22. A curved opening 622 is provided on one side of the connecting plate 67 to accommodate the rotating rod 619, preventing the rotating rod 619 from interfering with the connecting plate 67 during adjustment of the drill bit 64. When the cutting mechanism is in operation, it drives the fixed block 23 to move, causing the rotating rod 619 to contact the fixed block 23. Driven by the fixed block 23, the rotating rod 619 rotates, allowing the milling cutter 65 to approach the material and process the side grooves of the material. The provision of the tension spring 621 ensures that the rotating bar 618 maintains a stable position when not subjected to external forces.

[0074] The top of the support platform 11 is bolted to a connecting seat 61. A rotating ring 62 and a rotating ring 63 are rotatably mounted on either side of the connecting seat 61, respectively, via bearings. A connecting plate 67 is welded between the rotating rings 62 and 63. A transmission rod 16 is rotatably mounted between the connecting seats 61 and 13, via bearings. This transmission rod 16 is connected to the rotating rings 63 and 14 via a timing belt and a synchronous pulley. The output end of the motor 15 is fixedly connected to the transmission rod 16. Thus, when the motor 15 is activated, it simultaneously drives the turning mechanism and the drilling mechanism to perform a turning motion, achieving coordinated operation of the drilling and turning mechanisms. During the product turning process, the drilling mechanism is driven to turn and drill holes on the remaining surfaces in sequence.

[0075] During use, the raw material (martensitic stainless steel, hardness HB 150-250) is placed on the multiple guide wheels 42, the No. I electromagnet block 44 is started, so that the No. I electromagnet block 44 is adsorbed on the surface of the raw material, and the No. I motor 46 is started to drive the No. I screw 45. During the rotation of the No. I screw 45, it can cooperate with the nut block at the bottom of the No. I electromagnet block 44 to drive the No. I electromagnet block 44 to move. The movement of the No. I electromagnet block 44 can also drive the movement of the raw material.

[0076] Start the No. II motor 52 to drive the milling head 53 to rotate. When the raw material contacts the milling head 53, the milling head 53 can be used to mill the raw material into a square shape.

[0077] The square material after milling is moved to one side of the milling cutter 65, and the No. II electric push rod 18 is started to extend, driving the cutting disc 21 to move, and at the same time the No. VI motor 20 is started to drive the cutting disc 21 to rotate, which can cut off the waste material at one end of the material. At the same time, the No. III motor 66 is started to drive the drill bit 64 to rotate. During the rotation of the drill bit 64, the milling cutter 65 can be driven to rotate through the synchronous belt synchronous wheel or gear set. When the fixed block 23 contacts the rotating rod 619, it can drive the rotating rod 619 to approach the material. During the approach, the milling cutter 65 can process the corners of the product.

[0078] After the processing is completed, the No. 1 motor 46 is started to convey the material, and one end of the material moves into the No. 2 rotating ring 63, and the No. 3 motor 66 is started to drive the two drill bits 64 to rotate, and the No. 1 electric push rod 617 is started to retract. During the retraction process, the drill bit 64 can move downward to drill the through hole of the product, and the No. 5 motor 15 is started to drive the transmission rod 16 to rotate. The rotation of the transmission rod 16 can drive the No. 2 rotating ring 63 to rotate through the synchronous wheel and the synchronous belt. The rotation of the No. 2 rotating ring 63 can drive the drill bit 64 to rotate and move, so that the drill bit 64 moves to the side of the material. At the same time, the No. 4 motor 616 is started to drive the two drill bits 64 to approach each other, and the distance between the two drill bits 64 is adjusted to drill the installation cavity on the side of the product until the installation cavity on both sides of the product is drilled.

[0079] Continue to start the No. Ⅰ motor 46 to convey the material, so that the material moves into the clamp 12, and then start the clamp 12 to clamp it, and start the No. Ⅲ motor 66 to mill the through hole on the top of one side of the product, and at the same time start the No. Ⅱ electric push rod 18 to drive the fixed block 23 to move, and again resist the milling cutter 65 to approach the material to process the next groove to be processed. After the drilling is completed, the vertical milling machine 1 is started to mill the step on one side of the upper surface, and the clamp 12 is started to release the material, and continue to start the No. Ⅰ motor 46 to convey the material, so that the drilled material moves into the No. Ⅲ rotating ring 14, and at the same time start the No. Ⅱ clamping block 25, so that the No. Ⅱ clamping block 25 is adsorbed on the surface of the material and stuck in the groove on the outside;

[0080] At this time, the groove that has been processed previously moves to one side of the cutting blade 21, and the No. II electric push rod 18 is started to drive the cutting blade 21 to move, and the No. VI motor 20 is started to drive the cutting blade 21 to rotate to cut the square raw material. After cutting, the vertical milling machine 1 is started again to mill the step on the other side, and then the drilling assembly 6 is started to process the next through hole to be processed in the product, and the No. III motor 66 is started to drive the two drill bits 64 to rotate, and the No. I electric push rod 617 is started to retract. During the retraction process, the drill bit 64 can move downward to drill the through hole of the product;

[0081] After the processing is completed, the No. 1 clamp block 24 is started to be adsorbed on the surface of the product, the product is further fixed, the No. 5 motor 15 is started to drive the No. 3 rotating ring 14 to rotate, the product can be turned over, the drilling assembly 6 is started to mill the groove of the product, and the drill bit 64 rotates together with the No. 3 rotating ring 14 to adjust during the rotation of the No. 3 rotating ring 14, and the subsequent product groove is drilled in turn.

[0082] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, and they should be covered in the scope of the claims of the present application.
