Description

Technical Field

[0001] This utility model relates to the field of automated processing technology, specifically a CNC length-fixing frame for industrial automated production. Background Technology

[0002] In industrial automated production processes, CNC length-cutting frames are widely used for the precise cutting and positioning of materials such as metal sheets and pipes. Traditional length-cutting devices typically employ a mechanical baffle structure, using a cylinder to drive the baffle for positioning to meet the processing requirements of different sizes. However, existing technologies still have certain limitations in practical applications.

[0003] The original fixed-length main structure used two channel steels as the main frames on both sides, with angle irons installed inside the channel steels as guide rails. Vertical slits were cut along fixed dimensions on the angle irons, and cylinders were fixed to one side of the angle iron by drilling, tapping threads, and installing screws. A baffle was then connected, and finally, a solenoid valve controlled the cylinder to achieve the fixed-length function. From the perspective of equipment durability and accuracy, long-term, high-frequency use resulted in severe wear on the angle iron vertical slits and the baffle. Due to the frequent stress and friction during the fixed-length operation, wear was unavoidable. Once wear occurred, long-term welding repairs were required, increasing equipment maintenance costs and downtime, and repeatedly welding could alter the local properties of the angle iron. Furthermore, the wide variety of processing dimensions required numerous vertical slits to be cut on the angle iron, further weakening its mechanical properties and leading to a continuous decrease in fixed-length accuracy, making it difficult to meet increasingly stringent product dimensional accuracy requirements. In terms of production efficiency, the diversity of processing dimensions necessitated frequent changes in the position of the cylinder baffle by the operator. Each repositioning requires time and effort, increasing the workload of operators and severely impacting the overall production rhythm. Especially when order volumes are high and production schedules are tight, frequent repositioning significantly hinders efficiency improvements. Traditional structures have room for efficiency improvement when handling multi-specification processing. Operators frequently need to change the position of cylinder baffles during daily work, requiring them to be in close contact with moving parts; even slight carelessness can lead to injuries such as pinching or collisions. Furthermore, prolonged and frequent operation can cause operator fatigue and complacency, further increasing safety risks. Utility Model Content

[0004] The present invention aims to solve the above problems, thereby providing a CNC length-fixing frame that ensures more efficient industrial automated production.

[0005] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0006] A CNC length-measuring frame for industrial automated production includes a support frame. A set of load-bearing beams are arranged parallel to each other on the top of the support frame. Angle steel guide rails are respectively arranged on opposite sides of the load-bearing beams. A control panel is arranged on the side of the support frame. A movable table is slidably connected to the angle steel guide rails. A baffle is vertically arranged at the bottom of the movable table near the feeding side. The baffle is clearance-fitted with the angle steel guide rails. A drive mechanism connected to the control panel is provided between the movable table and the load-bearing beams. The drive mechanism drives the movable table to move axially along the angle steel guide rails.

[0007] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:

[0008] This invention avoids the positioning accuracy degradation caused by mechanical wear in traditional devices, reducing the need for manual welding repairs. The integrated guide rail structure and CNC adjustment significantly reduce the workload of operators adjusting the baffle position and improve the efficiency of switching between different sized processing tasks. By optimizing the structural layout and motion control method, direct contact between personnel and moving parts during operation is reduced, lowering safety hazards such as pinching and collision injuries, while also avoiding the risk of operator fatigue due to frequent operation. Compared to traditional cylinder-driven baffle structures, this invention effectively solves the problems of insufficient accuracy, difficult maintenance, low efficiency, and safety risks inherent in existing technologies while maintaining positioning functionality, providing a more reliable and efficient length-fixing solution for industrial automated production.

[0009] As a preferred embodiment, a further technical solution of this utility model is:

[0010] Furthermore, the drive mechanism includes a reducer and a motor fixed on the moving platform. A sprocket is connected to the output end of the reducer. Supports are respectively set at both ends of the top of one of the load-bearing beams along the length direction. A chain that meshes with the sprocket is tensioned between the supports. The motor drives the reducer to rotate the sprocket, which, together with the tensioned chain, enables the moving platform to move smoothly. The chain drive method has high transmission efficiency and reliability and can adapt to the needs of long-term high-frequency use. The reducer can precisely control the moving speed and improve positioning accuracy. Compared with traditional cylinder drive, the CNC adjustment method reduces manual intervention and facilitates rapid response to processing needs of different sizes.

[0011] Furthermore, a pointer extending towards the supporting beam is provided on one side of the top of the moving platform, and a scale that works in conjunction with the pointer is provided on the top of the supporting beam along its length. The pointer and the scale form an intuitive positioning reference, which helps the operator to quickly determine the position of the baffle. The visual assistance and the CNC system work together to help reduce the possibility of human error.

[0012] Furthermore, the vertical surfaces of both angle steel guide rails are located on the inner side, and the bottom of the moving platform is equipped with guide wheels that are slidably connected to the vertical surfaces of the angle steel guide rails. The vertical surfaces of the guide rails serve as the sliding reference surfaces of the moving platform, guiding the baffle to move linearly. The inner layout of the double guide rails forms a symmetrical force-bearing structure, which can counteract lateral offset forces and improve movement stability.

[0013] Furthermore, the top of the angle steel guide rail is equipped with a wear-resistant alloy liner, and a high-hardness material layer is added to the contact surface of the guide rail to reduce friction loss. The alloy material can effectively resist high-frequency friction and extend the service life of key components.

[0014] Furthermore, an absolute encoder is installed on the guide wheel, and a power-off self-locking electromagnetic brake is installed on the motor output shaft. The motor shaft brake and the guide wheel encoder form a safety redundancy system. The absolute encoder provides a position memory function that does not depend on the power supply, and the power-off self-locking mechanism ensures that the current position is maintained in the event of an unexpected power outage.

[0015] Furthermore, a pair of pneumatic cleaning nozzles are installed on the moving platform near the feeding side, opposite to the angle steel guide rail. These nozzles directionally remove debris and dust from the surface of the guide rail on the feeding side, keeping the guide rail contact surface clean and reducing jamming or accuracy reduction caused by foreign objects. Non-contact cleaning avoids additional friction on the moving parts. Attached Figure Description

[0020] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0021] A CNC length-measuring frame for industrial automated production includes a support 1. A set of load-bearing beams 2 are arranged parallel to each other on the top of the support 1. The ends of the load-bearing beams 2 are welded together by connectors. Angle steel guide rails 3 are respectively arranged on opposite sides of the load-bearing beams 2. The two angle steel guide rails 3 are laser-calibrated and welded to the load-bearing beams 2. A control panel is arranged on the side of the support 1. A moving table is slidably connected to the angle steel guide rails 3. A baffle 4 is vertically arranged at the bottom of the moving table near the feeding side. A mounting frame is provided at the bottom of the moving table. The baffle 4 is detachably connected to the mounting frame by bolts. There is a clearance fit between the baffle 4 and the angle steel guide rails 3, maintaining a gap of 1-2mm between the baffle 4 and the angle steel guide rails 3. A drive mechanism connected to the control panel is provided between the moving table and the load-bearing beams 2. The drive mechanism drives the moving table to move axially along the angle steel guide rails 3.

[0022] Furthermore, the drive mechanism includes a reducer 5 and a motor 6 fixed on the moving platform. The control panel has a built-in PLC controller that controls the motor 6 via pulse signals. The output shaft of the motor 6 is connected to the reducer 5. The reducer 5 is a cycloidal pin reducer, and a sprocket is connected to the output end of the reducer 5. Supports 7 are respectively set at both ends of the top of one of the load-bearing beams along the length direction. A chain 8 that meshes with the sprocket is tensioned between the supports 7. The motor 6 drives the reducer 5 to rotate the sprocket, and the tensioned chain 8 enables the moving platform to move smoothly, which can meet the needs of long-term high-frequency use. The reducer 5 can precisely control the moving speed and improve the positioning accuracy. Compared with traditional cylinder drive, the CNC adjustment method reduces manual intervention and facilitates rapid response to processing needs of different sizes.

[0023] Furthermore, a pointer 9 extending towards the support beam 2 is provided on one side of the top of the moving table. A scale is provided on the top of the support beam 2 along the length direction to cooperate with the pointer 9. The axis of the pointer 9 coincides with the surface of the baffle 4 near the feed side. The pointer 9 and the scale form an intuitive positioning reference, which helps the operator to quickly judge the position of the baffle 4. The visual assistance and the CNC system work together to help reduce the possibility of human error.

[0024] Furthermore, the facades of both angle steel guide rails 3 are located on the inner side, and the bottom of the moving platform is equipped with guide wheels that are slidably connected to the facades of the angle steel guide rails 3. The guide wheels are made of polyurethane material, and the facades of the guide rails serve as the sliding reference surfaces of the moving platform, guiding the baffle 4 to move linearly. The inner layout of the double guide rails forms a symmetrical force-bearing structure, which can counteract lateral offset forces and improve movement stability.

[0025] Furthermore, the top of the angle steel guide rail 3 is provided with a wear-resistant alloy liner, and a high-hardness material layer is added to the contact surface of the guide rail to reduce friction loss. The alloy material can effectively resist high-frequency friction and extend the service life of key components.

[0026] Furthermore, an absolute encoder is installed on the guide wheel, and a power-off self-locking electromagnetic brake is installed on the output shaft of motor 6. The absolute encoder and the power-off self-locking electromagnetic brake are connected to the control panel through the PLC controller. The motor shaft brake and the guide wheel encoder form a safety redundancy system. The absolute encoder provides a position memory function that does not depend on the power supply, and the power-off self-locking mechanism ensures that the current position is maintained in the event of an unexpected power outage.

[0027] Furthermore, a pair of pneumatic cleaning nozzles 10 are installed on the moving platform near the feeding side, opposite to the angle steel guide rail 3. The pneumatic cleaning nozzles 10 are connected to the air source pipe through quick-connect couplings to directionally remove debris and dust from the surface of the guide rail on the feeding side, keeping the guide rail contact surface clean and reducing jamming or accuracy reduction caused by foreign objects. Non-contact cleaning avoids additional friction on the moving parts. The spray angle of the pneumatic cleaning nozzles 10 is adjustable between 30-45°.

[0028] After the operator inputs the target size parameters through the control panel, the motor 6 starts running, driving the moving table along the angle steel guide rail 3 via the sprocket and chain 8 transmission mechanism. During the movement, the absolute encoder monitors the rotation speed of the guide wheel in real time and feeds back the position signal, ultimately positioning the baffle 4 at the target position. After positioning, the electromagnetic brake immediately activates to lock the motor shaft, while the pneumatic chip removal nozzle 10 sprays compressed air to remove metal debris from the surface of the guide rail. Throughout the process, the friction pair formed by the wear-resistant alloy liner and the polyurethane guide wheel can stably withstand high-frequency sliding, while the symmetrical structure of the double guide rail inner layout effectively suppresses lateral offset force. When it is necessary to verify the positioning accuracy, the operator can quickly confirm it by observing the correspondence between the pointer 9 and the scale. In the event of a sudden power failure, the dual protection of the power failure self-locking brake and the absolute encoder can maintain the current position memory.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
