Description

Technical Field

[0001] This invention relates to the field of comb tooth processing machinery and equipment, specifically to an automatic tooth-opening device for simultaneous cutting of multiple comb teeth. Background Technology

[0002] Automatic finger jointing equipment is a specialized processing device that uses automated machinery or CNC systems to cut specific tooth-shaped structures on the end face / groove of a workpiece to achieve splicing, connection, or enhanced bonding. It is used to mill the end face of short timber into interlocking comb-like teeth (finger joint), and together with glue, to extend the timber. It is widely used in the production of construction formwork, furniture, and flooring. In the prior art, patent document CN109093861A discloses an automatic cam synchronous cutting machine, which includes a mechanical connection part, a cutting part, and a worktable moving part. In the mechanical connection part, a K-series helical gear reducer located on one side of the frame is connected to the cam shaft. The synchronous cam, conjugate small cam, and conjugate large cam are mounted on the cam shaft. To meet the enterprise's pursuit of productivity and product quality, this design achieves synchronous and automated cutting and chamfering of bricks and tiles, improving cutting output and accuracy. The cutting length can be digitally adjusted, and the equipment occupies little space. To achieve the above design objectives, the automated synchronous cutting machine features a clever mechanical structure design. From automatic feeding via belt conveyor to cutting and then to discharge via belt conveyor, the entire process is automated with no material return. The cam mechanism and remote lever slider mechanism are used to synchronously cut during belt conveyor transport, making it highly practical. However, the above-mentioned technical solutions have low adjustment freedom and cannot achieve multi-dimensional displacement adjustment. They are poorly adaptable to different specifications and sizes of comb-tooth workpieces, and the equipment lacks versatility. Furthermore, traditional equipment lacks a dedicated workpiece angle adjustment structure, and the tooth opening angle is mostly manually calibrated, resulting in low alignment accuracy, large angle deviation, and easy occurrence of machining defects such as tooth skew and uneven tooth pitch, making it difficult to guarantee product yield. Moreover, the material fixing structure is rudimentary, and the workpiece is prone to loosening, displacement, and vibration during processing. Under high-speed cutting conditions, the processing stability is poor, and defects such as tooth breakage and burrs are easily generated. In addition, the traditional milling cutter cutting structure lacks precise limit and deceleration protection structures, and the milling cutter rotation speed and cutting force are uncontrollable. High-speed cutting is prone to tool vibration and cutting deviation, and there are no multiple limit protection structures, posing significant safety hazards to the operation. Based on this, the present invention provides an automatic tooth-opening device for synchronous cutting of multiple comb teeth to solve the problems mentioned in the background art. Summary of the Invention

A milling cutter limiting structure is installed on the other side of the top of the base plate. The three drive motors are used as the power output for the milling cutter cutting operation. The motor output end is fixed with a drive connector, which serves to transfer power and fix the transmission rods.

[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: the outer wall of the threaded rod is connected to the transmission block, and during the rotation of the threaded rod, the transmission block can be driven to slide vertically along the top slide plate. The top of the transmission block is fixed with the transmission plate, which can move synchronously with the transmission block to realize the alignment of the longitudinal adjustment structure with the workpiece and the cutting structure.

The top of the second threaded rod is equipped with a transmission seat, which can convert the rotational power of the threaded rod into linear displacement power. The side of the transmission seat is fixed with a fixed plate, providing a stable mounting carrier for the subsequent angle adjustment structure and workpiece clamping structure.

[0012] Furthermore, an angle adjustment structure is provided on one side of the fixed plate. The angle adjustment structure includes a mounting base fixed to one side of the outer wall of the fixed plate. A drive pump is installed on the inner wall of the mounting base. A pneumatic rod is installed at the output end of the drive pump. A rotating joint is installed at one end of the pneumatic rod. A rotating block is rotatably connected to the inner wall of the rotating joint. The rotating block passes through a slot opened in the inner wall of the mounting base, and a connecting plate is fixedly connected to one end of the rotating block.

[0013] Furthermore, two limiting sliders are installed on one side of the outer wall of the connecting plate, and an installation plate is sleeved on the outer wall of the two limiting sliders. A fixing seat is fixedly connected to one side of the installation plate, and a connector is installed at the output end of the fixing seat. A fixing clamp is installed at one end of the connector.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: a mounting base is fixed on one side of the outer wall of the fixed plate, and a drive pump is embedded in the inner wall of the mounting base. The output end of the drive pump is stably connected to the pneumatic rod. Relying on pneumatic drive, it can provide automated drive power for fine adjustment of the workpiece angle. A rotating joint is installed at the telescopic end of the pneumatic rod. A rotating block is nested inside the rotating joint to form a deflectable structure. A slot is opened on the inner wall of the mounting base, and the rotating block is arranged through the slot, which can deflect freely within the slot. During operation, the telescopic movement of the pneumatic rod can be transmitted to the rotating block through the rotating joint, driving the rotating block to complete a small angle deflection movement. A connecting plate is fixedly connected to the outside of the rotating block. The connecting plate can synchronously complete the angle deflection movement with the rotating block. The first plate drives the rear fixture and the workpiece to make overall fine-tuning of the cutting posture. It can match the optimal cutting angle according to the tooth shape requirements of the workpiece, and is suitable for multi-angle and irregular comb tooth opening processing scenarios. Two limiting sliders are symmetrically arranged on the outer wall of the connecting plate. The outer wall of the slider is slidably sleeved with the mounting plate. The clearance between the two is highly accurate. The mounting plate can slide smoothly along the limiting slider, which can provide guidance and limit for angle adjustment and fixture alignment, effectively alleviating the problems of offset and jamming during the sliding process. The outer side of the mounting plate is fixedly equipped with a fixing seat 1, which serves as the transfer fixing base of the fixture. The output end of the fixing seat 1 is equipped with a connector. The fixing fixture is docked and positioned through the connector. The fixing fixture can stably clamp various comb tooth workpieces to be processed.

[0015] Furthermore, a material stabilizing structure is provided on one side of the outer wall of the transmission block. The material stabilizing structure includes a connecting base plate fixed to one side of the outer wall of the transmission block. A top plate is installed on the top of the connecting base plate through multiple support rods. A connecting groove plate is fixedly connected to one side of both the top plate and the connecting base plate. Sliding blocks are slidably connected to the inner walls of the multiple connecting groove plates. A side connecting plate is welded to one side of each of the multiple sliding blocks. A rotating connecting rod is installed on the side of the multiple side connecting plates away from the sliding blocks.

[0016] A second connecting plate is installed on one end of each of the multiple rotating connecting rods away from the side connecting plate. A support plate is installed on one side of each of the multiple second connecting plates. A telescopic support is fixedly connected to the side of each of the multiple support plates away from the second connecting plate. The multiple telescopic supports are grouped in pairs, and a clamping plate is fixedly connected to one side of each group of telescopic supports.

[0017] Each of the clamping plates is rotatably connected to a connecting bracket at its center. Each of the connecting brackets has a spring rod installed at one end. Each of the spring rods has a bottom support fixedly connected to the end away from the connecting bracket. Each of the bottom supports is located between the connecting slot plates.

[0018] The beneficial effects of adopting the above-mentioned further solution are as follows: a base plate is fixedly connected to one side of the outer wall of the transmission block, and the overall clamping structure is fixed on the transmission block based on the connecting base plate. It can synchronously complete the displacement adjustment with the transmission block. The top plate is supported by multiple sets of evenly distributed support rods at the top of the connecting base plate. The support rods, the top plate, and the connecting base plate together form a closed frame support. The top plate and the inner side of the connecting base plate are symmetrically fixedly connected to the groove plate. The inner wall of the groove plate is slidably equipped with sliding blocks. The gap between the sliding blocks and the groove plate is reasonably matched, allowing free and stable displacement along the track. The position of the sliding blocks can be flexibly adjusted according to the workpiece specifications to realize the adjustment of the clamping distance. Side connecting plates are welded and fixed to the outside of multiple sliding blocks. Rotating connecting rods are rotatably assembled on the outside of the side connecting plates. The synchronous opening and closing and spacing adjustment of multiple sets of clamping structures can be realized through the rotation of the connecting rods. Connecting plate two is assembled at the end of multiple rotating connecting rods. Connecting plate two can transmit the opening and closing power of the rotating connecting rods to the outer support plate. Telescopic supports are fixedly assembled on the outside of multiple support plates. The telescopic supports can be extended and adjusted. Each set The telescopic support is equipped with a clamping plate. During operation, the clamping stroke can be adaptively adjusted according to the workpiece thickness by relying on the telescopic support's extension and retraction. This allows the clamping plate to flexibly conform to the workpiece surface, accommodating batch processing of workpieces of various specifications. The equipment uses multiple sets of clamping plates to apply clamping force simultaneously from multiple points on both sides of the comb-shaped workpiece, ensuring uniform and balanced force on the workpiece and maintaining workpiece stability during cutting. A connecting bracket is rotated and mounted at the center of the clamping plate. The connecting bracket can adaptively fine-tune the contact angle of the clamping plate 413. A spring rod is fixedly mounted at the end of the connecting bracket, which can absorb cutting vibration stress and clamping overload stress, avoiding workpiece crushing damage and component loosening caused by stress concentration. A bottom support is fixedly mounted at the bottom of the spring rod. The bottom support is neatly arranged between multiple sets of connecting slot plates, providing a fixed support benchmark for the elastic extension and retraction of the spring rod. This effectively disperses the load pressure during the elastic buffering process, preventing the elastic structure from shifting or loosening during long-term operation and ensuring the long-term stable operation of the buffer mechanism.

[0019] The outer wall of the sprocket assembly is fitted with a transmission box, and the other end of the sprocket assembly is equipped with a drive rod. One end of the drive rod passes through two limiting seats. A sealing plate seat is fixedly connected to one side of the two limiting seats. An external limiting cylinder is installed between the two sealing plates. The inner wall of the external limiting cylinder is provided with multiple limiting rotation grooves. The inner walls of the multiple limiting rotation grooves are rotatably connected to limiting rotation plates.

[0020] One end of the driving rod is penetrated by a fixed base two, and a milling cutter connecting shaft is installed at one end of the driving rod.

[0021] The beneficial effects of adopting the above-mentioned further solution are that the outer wall of the sprocket assembly is fitted with a closed transmission box, which can completely isolate the sprocket transmission area, forming an independent and sealed transmission space, ensuring smooth meshing and transmission of the sprocket assembly, reducing transmission noise and loss, and improving the stability of the transmission system. The power output end of the sprocket assembly is connected to the drive rod, and the drive rod body passes through two sets of symmetrically arranged limit seats, which can limit the radial runout and swing amplitude during the high-speed rotation of the long rod, and alleviate the vibration and offset problems that are prone to occur in long-distance transmission. The outer side of the two sets of limit seats is fixed with sealing plates, and the external limit is stably assembled between the two sealing plates. The cylinder forms a closed protection. Multiple sets of limiting rotation grooves are arranged in a ring on the inner wall of the limiting cylinder. The limiting rotation plate is mounted in the groove, which can limit and guide the outer periphery of the driving rod in all directions, further constraining the rotation trajectory of the rod. The multi-layer protective structure works together. The end of the driving rod is mounted with a fixed seat two, which can limit and support the end of the rod, effectively constraining the swaying amplitude of the end of the rod and improving the problem of insufficient transmission stability at the end of long rods. The end of the driving rod is fixedly mounted with a milling cutter connecting shaft. A quick-disassembly connecting shaft that is compatible with a variety of conventional toothed milling cutters can be selected for more convenient use.

[0022] The bottom plate has a bottom material support plate embedded at its top, and the bottom plate has four fixed feet at its bottom corners. A mounting groove is provided on one side of the bottom of the bottom plate, and a drive motor is installed on the inner wall of the mounting groove.

[0023] The beneficial effects of adopting the above-mentioned further solution are that the bottom of the equipment uses a base plate as the supporting base of the whole machine, and a bottom material support plate is embedded at the top of the base plate. The surface of the plate is flattened, which can provide a support platform for processing comb-tooth workpieces of different specifications. The four corners of the bottom end of the base plate are fixed with feet to provide balanced support for the whole machine. A mounting groove is opened on one side of the bottom end of the base plate for embedding and installing the drive motor, mainly for storing and fixing the drive motor. This embedded layout can effectively reduce the external space occupied by the equipment and optimize the compactness of the overall structure. Attached Figure Description

A telescopic support 412 is fixedly connected to the side of each of the multiple support plates 48 away from the connecting plate 47. The multiple telescopic supports 412 are in pairs, and a clamping plate 413 is fixedly connected to one side of each pair of telescopic supports 412.

[0035] Multiple clamping plates 413 are rotatably connected to connecting brackets 49 at their center positions. Each of the multiple connecting brackets 49 has a spring rod 410 installed at one end. Each of the multiple spring rods 410 has a bottom support 411 fixedly connected to the end away from the connecting bracket 49. The multiple bottom supports 411 are located between multiple connecting slot plates 43.

[0036] A base plate 4 is fixedly connected to one side of the outer wall of the transmission block 26. The overall clamping structure is fixed to the transmission block 26 based on the base plate 4, and can synchronously adjust its displacement with the transmission block 26. A top plate 42 is supported at the top of the base plate 4 by multiple sets of evenly distributed support rods 41. The support rods 41, the top plate 42, and the base plate 4 together form a closed frame support. A groove plate 43 is symmetrically fixed to the inner side of the top plate 42 and the base plate 4. A sliding block 44 is slidably assembled on the inner wall of the groove plate. The gap between the sliding block 44 and the groove plate is reasonably matched, allowing for free and stable displacement along the track. The displacement can be adjusted according to the workpiece. The sliding block 44 is flexibly adjustable to achieve the adjustment of the clamping distance. Side connecting plates 45 are welded and fixed to the outside of multiple sliding blocks 44. Rotating connecting rods 46 are rotatably mounted on the outside of the side connecting plates 45. The rotation of the connecting rods 46 allows for the synchronous opening and closing and spacing adjustment of multiple clamping structures. Connecting plates 47 are mounted at the ends of the multiple rotating connecting rods 46, transmitting the opening and closing power of the rotating connecting rods 46 to the outer support plates 48. Telescopic supports 412 are fixedly mounted on the outside of the multiple support plates 48. The telescopic supports 412 are retractable and finely adjustable. Each set... The telescopic support 412 is equipped with a clamping plate 413. During operation, the clamping stroke can be adaptively adjusted according to the workpiece thickness by relying on the telescopic support 412 to drive the clamping plate 413 to flexibly fit the workpiece surface. This is suitable for batch processing of workpieces of various specifications. The equipment uses multiple sets of clamping plates 413 to apply clamping force simultaneously from multiple points on both sides of the comb workpiece, so that the overall force on the workpiece is uniform and balanced, ensuring the stability of the workpiece posture during the cutting process. The connecting bracket 49 is rotatably mounted at the center position of the clamping plate 413. The connecting bracket 49 can be adapted to the contact angle of the clamping plate 413. The adaptive fine-tuning is achieved by fixing a spring rod 410 at the end of the connecting bracket 49. This absorbs cutting vibration stress and clamping overload stress, preventing workpiece crushing damage and component loosening caused by stress concentration. A bottom support 411 is fixedly mounted at the bottom of the spring rod 410. The bottom support 411 is neatly arranged between multiple sets of connecting slot plates 43, providing a fixed support benchmark for the elastic extension and contraction of the spring rod 410. This effectively disperses the load pressure during the elastic buffering process, preventing the elastic structure from shifting or loosening during long-term operation, and ensuring the long-term stable operation of the buffer mechanism.

[0037] A transmission box 52 is fitted on the outer wall of the sprocket assembly 53, and a drive rod 56 is installed on the other end of the sprocket assembly 53. One end of the drive rod 56 passes through two limit seats 57. A sealing plate seat 510 is fixedly connected to one side of the two limit seats 57. An external limit cylinder 58 is installed between the two sealing plate seats 510. Multiple limit rotation grooves 59 are opened on the inner wall of the external limit cylinder 58. Limit rotation plates 511 are rotatably connected to the inner walls of the multiple limit rotation grooves 59.

[0038] One end of the drive rod 56 is connected to the fixed base 512, and a milling cutter connecting shaft 513 is mounted on one end of the drive rod 56.

[0039] The outer wall of the sprocket assembly 53 is fitted with a closed transmission box 52, which completely isolates the sprocket transmission area, forming an independent and sealed transmission space. This ensures smooth meshing and transmission of the sprocket assembly 53, reduces transmission noise and losses, and improves the stability of the transmission system. The power output end of the sprocket assembly 53 is connected to the drive rod 56. The drive rod 56 passes through two sets of symmetrically arranged limiting seats 57, which can limit the radial runout and swing amplitude of the long rod during high-speed rotation, alleviating the vibration and offset problems that are prone to occur in long-distance transmission. The outer side of the two sets of limiting seats 57 is fixed with a sealing plate seat 510, and an external limiting cylinder 58 is stably assembled between the two sealing plate seats 510 to form a closed anti-vibration system. The outer limiting cylinder 58 has multiple sets of limiting rotation grooves 59 arranged in a ring on its inner wall. The limiting rotation plate 511 is mounted in the groove and can limit and guide the outer periphery of the driving rod 56 in all directions, further constraining the rotation trajectory of the rod. The multi-layer protective structure works together. The end of the driving rod 56 is fitted with a fixed seat 512, which can limit and support the end of the rod, effectively constraining the swaying amplitude of the end of the rod and improving the problem of insufficient transmission stability at the end of the long rod. The end of the driving rod 56 is fixedly fitted with a milling cutter connecting shaft 513. A quick-disassembly connecting shaft that is compatible with a variety of conventional toothed milling cutters can be selected for easier use.

[0040] The bottom plate 1 is fitted with a bottom material support plate 11 at the top, and the bottom plate 1 is fixedly connected with four corners of the bottom. The bottom plate 1 has a mounting groove 13 on one side, and a drive motor 25 is installed on the inner wall of the mounting groove 13.

[0041] The equipment uses a base plate 1 as the supporting structure. A bottom material support plate 11 is embedded at the top of the base plate 1. The plate surface is flattened to provide a support surface for processing comb-tooth workpieces of different specifications. Four fixed support feet 12 at the bottom corners of the base plate 1 provide balanced support for the entire machine. A mounting groove 13 is provided on one side of the bottom of the base plate 1 for embedding and mounting a drive motor 25, primarily for storing and fixing the drive motor 25. This embedded layout effectively reduces the external space occupied by the equipment and optimizes the overall structural compactness.

[0042] The working principle of this invention is as follows: The operator places the pre-treated comb-tooth workpiece on the surface of the bottom material support plate 11. The position of the sliding block 44 is adaptively adjusted according to the workpiece specifications, causing multiple clamping plates 413 to fit against both sides of the workpiece. Flexible and stable clamping is achieved through the elastic buffer of the spring rod 410, ensuring the workpiece is centered. The drive motor 25 is started, driving the threaded rod 22 to rotate via the transmission wheel set 24, driving the transmission block 26 to slide laterally, completing the lateral cutting and alignment of the workpiece. The drive motor 28 is started, driving the transmission seat 211 to move longitudinally via the threaded rod 210, completing the longitudinal alignment. The drive pump 3 is started according to the workpiece tooth profile requirements. 1. The pneumatic rod 32 extends and retracts, driving the rotating block 34 to deflect and adjust the workpiece cutting angle to adapt to the tooth opening requirements of irregular and arc-shaped combs. After alignment, the drive motor 35 is started, which drives the sprocket group 53 and the reduction wheel 54 to rotate through the drive connecting seat 51. The rotation is then transmitted to the milling cutter connecting shaft 513 via the drive rod 56, driving the milling cutter to rotate at high speed and stably. During the cutting process, the spring rod 410 continuously provides elastic buffering force to offset the vibration stress generated by high-speed cutting and prevent workpiece displacement and chipping. The transmission box 52 and the external limiting cylinder 58 protect the core transmission components throughout the process, preventing processing dust and debris from entering the transmission area and ensuring the continuous and stable operation of the equipment.
