Description

Technical Field

[0001] The present invention belongs to the technical field of manufacturing installation accessories for air - energy heat pump heating machines. More specifically, it relates to a hole - punching device for processing installation frames of variable - frequency air - energy heat pump heating machines. Background Art

[0002] As an energy - efficient heating device, the outdoor unit of a variable - frequency air - energy heat pump heating machine needs to be fixed to the building facade or the ground through an installation frame. The installation frame is mainly composed of profiles such as angle steel and channel steel to form a frame structure, which needs to bear the weight of the unit and the vibration load during operation. To ensure structural stability, each component of the installation frame needs to be rigidly connected by bolts, which requires high - precision installation holes to be processed at specific positions on the profiles. Currently, the commonly used segmented hole - punching process is as follows: first, position and mark on the profile according to the design drawing, then process through - holes one by one with a bench drill or a magnetic drill, and finally complete the assembly with bolts and lock washers. This connection method has strict requirements for hole - position accuracy. If the hole - pitch deviation exceeds ±1 mm, it may cause the frame to deform, thereby affecting the installation level and shock - absorption effect of the unit.

[0003] The existing hole - punching devices for installation frames have the following defects: Since the length of the installation - frame parts usually reaches 1.5 - 3 meters (such as the main load - bearing beam), when processing the hole positions at both ends, the effective stroke of the traditional drill - press workbench is insufficient. The operator needs to clamp one end to complete the hole - punching first, and then loosen the fixture and re - adjust the workpiece position to process the other end. This repeated positioning not only increases the single - piece processing time by more than 40%, but also easily generates cumulative errors due to secondary clamping. Practical tests show that when the length of the profile exceeds 2 meters, the hole - pitch deviation caused by manual re - clamping can reach ±2.3 mm. Summary of the Invention

Detailed implementation manners

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] Refer to Figures 1 to 8 , and now a punching device for processing an installation frame of a variable-frequency air energy heat pump heating machine provided by the present invention will be described.

[0020] A punching device for processing an installation frame of a variable-frequency air energy heat pump heating machine includes a frame 1 and a punching mechanism 2, a clamping mechanism 3 and a driving mechanism 5 fixedly connected to the frame 1. The clamping mechanism 3 includes a first clamping assembly 31 and a second clamping assembly 32; the first clamping assembly 31 and the second clamping assembly 32 are respectively arranged on both sides of the punching mechanism 2, and the structures of the first clamping assembly 31 and the second clamping assembly 32 are the same; the first clamping assembly 31 includes a support member 311 and a telescopic member 312 connected to the frame 1; both the support member 311 and the telescopic member 312 are vertically arranged, and the telescopic member 312 is arranged directly above the support member 311; the telescopic member 312 is arranged above the workpiece, and the support member 311 is arranged below the workpiece. The driving mechanism 5 abuts against the workpiece and is used to adjust the position of the workpiece.

[0021] When drilling a workpiece, first place the workpiece between the clamping mechanisms 3 and clamp it. At the same time, bring the driving mechanism 5 into contact with the workpiece. Then drive the workpiece to move through the driving mechanism 5 so that the drilling position at one end of the workpiece is located below the drilling mechanism 2. When the workpiece moves into place, the driving mechanism 5 stops working. At this time, the first clamping component 31 or the second clamping component 32 in the clamping mechanism 3 clamps the end of the workpiece, and the driving mechanism 5 clamps and fixes the middle part of the workpiece by using friction. The first clamping component 31 or the second clamping component 32 cooperates with the driving mechanism 5 to clamp and fix the position of the workpiece. After one end of the workpiece is drilled, when other parts of the workpiece need to be drilled, the operator starts the driving mechanism 5, and the driving mechanism 5 drives the workpiece to move between the first clamping component 31 or the second clamping component 32, so as to move the part to be drilled directly below the drilling mechanism 2.

[0022] When drilling the workpiece, the drilling mechanism 2 exerts a downward force on the workpiece. At the same time, the telescopic member 312 in the first clamping component 31 or the second clamping component 32 on the other side of the driving mechanism 5 also exerts a downward force on the workpiece. At this time, the workpiece takes the driving mechanism 5 as a fulcrum, and the forces borne by its two ends will be balanced, avoiding the deflection of the workpiece during the drilling process.

[0023] In a preferred embodiment, the telescopic member 312 is specifically a cylinder. The cylinder mainly consists of core components such as a cylinder barrel, a piston, end covers, and a piston rod. Among them, the cylinder barrel is fixedly connected to the frame 1. The cylinder barrel is a hollow cylindrical structure, usually made of aluminum alloy or stainless steel, and its inner wall is precision machined to ensure smoothness. The piston is installed inside the cylinder barrel and is connected to an external load through the piston rod. Seals are installed on the piston to prevent gas leakage. The end covers are located at both ends of the cylinder barrel, which not only play a sealing role but also have built-in buffer devices to absorb the impact force when the piston moves to the end. The guide sleeve is used to keep the piston rod moving linearly and prevent it from deflecting. In addition, the cylinder is equipped with a magnetic switch for detecting the piston position and a dust-proof ring to prevent external pollutants from entering the inside of the cylinder barrel. The whole structure is designed compactly, which is convenient for installation and use in various industrial environments.

[0024] The working principle of the cylinder is based on the energy conversion of compressed air. When compressed air enters one end of the cylinder through a solenoid valve, it pushes the piston to move to the other end, thereby driving the piston rod to output linear motion. If it is a double-acting cylinder, compressed air will alternately enter both ends of the cylinder to achieve reciprocating motion; a single-acting cylinder relies on a spring or external force to achieve reset. The movement speed and output force of the piston depend on the intake pressure and the effective area of the cylinder. The buffer device of the cylinder adjusts the exhaust speed to make the piston stop smoothly at the end of the stroke, reducing impact and noise. The whole process converts pneumatic energy into mechanical energy, which has the advantages of fast response, simple structure, and convenient maintenance, and is widely used in automated equipment and mechanical systems.

[0025] In a preferred embodiment, the telescopic member 312 is a hydraulic cylinder. The hydraulic cylinder mainly consists of a cylinder barrel, a piston, a piston rod, and a sealing device. The cylinder barrel, as the main structure, is made of high-strength alloy steel and has a smooth hydraulic oil passage formed by precision honing inside. The multi-stage piston is installed in the cylinder barrel in a nested manner, and each stage of the piston is equipped with a wear-resistant ring and a combined seal to ensure pressure isolation between the oil cavities of each stage. The surface of the piston rod is treated with hard chromium plating to improve corrosion resistance, and a threaded connection port is provided at the end for load installation. Special-designed guide sleeves are distributed between each stage of the piston to effectively prevent radial yaw during movement. A dust ring is installed at the root of the exposed piston rod to block external contaminants from entering the hydraulic system. The entire structure adopts a modular design, and the number of piston stages can be flexibly increased or decreased according to the stroke requirements.

[0026] The hydraulic cylinder realizes multi-stage synchronous extension and retraction through the pressure difference of hydraulic oil. When the pressure oil enters the innermost oil cavity, it pushes the first-stage piston to extend until it reaches the limit. Subsequently, the pressure oil enters the secondary oil cavities in sequence through the internal oil passage, driving the subsequent pistons to extend stage by stage, forming a deployment process similar to a telescope. During retraction, the oil circuit direction is changed through a reversing valve, and the pressure oil enters from the reverse oil port. Each stage of the piston retracts in sequence under the action of oil pressure and its own weight. The system pressure is precisely controlled by an overflow valve to ensure smooth thrust during each movement stage. The buffer device generates a throttling effect at the end of the stroke to achieve a flexible stop. This structure combines the characteristics of a large stroke and a small storage size, and has irreplaceable advantages in the fields of construction machinery and special vehicles.

[0027] In a preferred embodiment, the telescopic member 312 is specifically an electric telescopic rod. The electric telescopic rod mainly consists of a motor, a transmission mechanism, a telescopic rod body, and a control system. The motor usually adopts a DC brushed or brushless motor, and converts high-speed rotation into low-speed high-torque output through a reduction gear set. The transmission mechanism includes a precision ball screw or a planetary gear set, which converts rotational motion into linear motion. The rod body is made of high-strength aluminum alloy or stainless steel pipe, and multiple telescopic sleeves are nested inside. Wear-resistant guide rings and seals are installed between each sleeve. Limit switches are installed at both ends of the rod body to control the stroke range. The outer shell is made of engineering plastic or metal material, with both protection and heat dissipation functions. The control circuit board is integrated at the rear end of the motor and has overload protection and signal feedback functions.

[0028] The electric telescopic rod realizes precise linear displacement control through motor drive. After the control system issues an instruction, the motor drives the lead screw to rotate, pushing the internal nut to move axially, thereby driving the telescopic tubes of each stage to extend sequentially. The position sensor monitors the displacement in real time and ensures the positioning accuracy through closed-loop control. When retracting, the motor rotates in reverse, and each telescopic tube is retracted step by step through the transmission mechanism. The speed regulation is achieved by changing the input voltage of the motor through PWM technology, and the thrust depends on the motor power and transmission ratio. The intelligent control system can preset multiple stroke positions and has functions of stopping when encountering resistance and automatic reset. This electric drive method has the advantages of low noise, low energy consumption, and simple maintenance compared with traditional pneumatic and hydraulic systems, and is widely used in medical equipment, smart home, and industrial automation fields.

[0029] In a preferred embodiment, the punching mechanism 2 is a mechanical stamping punching mechanism 2. The mechanical stamping punching mechanism 2 adopts a crank-slider structure. The motor drives the flywheel to rotate, driving the connecting rod to move, so that the punch makes a vertical reciprocating motion. A fixed die is installed below the punch. When the material is placed between the die and the punch, the punch pressing down at high speed cooperates with the die to complete the shearing and punching. This mechanism has a large impact force and is suitable for processing hard materials such as metal plates. It can achieve 60 - 300 high-frequency punching operations per minute.

[0030] In a preferred embodiment, the punching mechanism 2 is a hydraulic punching mechanism 2. The hydraulic punching mechanism 2 consists of a hydraulic cylinder, a piston rod, and a punch needle. The hydraulic pump generates high-pressure hydraulic oil to push the piston rod to move linearly, driving the front punch needle to penetrate the material. By adjusting the pressure of the hydraulic system, the punching force can be precisely controlled, which is especially suitable for processing multi-layer composite materials or workpieces with uneven thickness. The hydraulic system has an overload protection function and will automatically relieve pressure when encountering super-hard materials to avoid equipment damage.

[0031] In a preferred embodiment, the punching mechanism 2 is a rotary punching mechanism 2. The rotary punching mechanism 2 mainly includes a high-speed spindle and a drilling tool. The servo motor drives the spindle to rotate at a speed of thousands of revolutions per minute, and at the same time, the axial feed movement is realized through a ball screw. The carbide or diamond-coated drill bit gradually penetrates the material during the rotary cutting process to form a round hole. This method has high processing accuracy and can complete the processing of micro holes, and is widely used in the manufacturing of PCB circuit boards and precision parts.

[0032] In a possible implementation manner, the first clamping assembly 31 further includes: The upper guide roller 313, which is rotatably connected to the bottom of the telescopic member 312; and The lower guide roller 314 is rotatably connected to the top of the support member 311; the upper guide roller 313 is arranged directly above the lower guide roller 314, the upper guide roller 313 is arranged above the workpiece, and the lower guide roller 314 is arranged below the workpiece; the rotating shafts of the upper guide roller 313 and the lower guide roller 314 are horizontal and perpendicular to the workpiece. When clamping the workpiece, the upper guide roller 313 and the lower guide roller 314 can apply equal pressure from the upper and lower sides of the workpiece, thereby fixing the workpiece. When adjusting the position of the workpiece, since both the upper guide roller 313 and the lower guide roller 314 can rotate freely, the position of the workpiece can be moved without canceling the pressure applied by the upper guide roller 313 and the lower guide roller 314 to the workpiece.

[0033] In a possible implementation manner, an upper slider 11 and a lower slider 12 are arranged on the frame 1; the top of the telescopic member 312 is fixedly connected to the upper slider 11; the bottom of the support member 311 is fixedly connected to the lower slider 12. There are two upper sliders 11 and two lower sliders 12, and two of the upper sliders 11 and two of the lower sliders 12 are respectively used to install the first adjustment assembly 43 and the second adjustment assembly 43.

[0034] During the actual processing, the lengths of the workpieces on the mounting rack are different. In order to clamp workpieces of different lengths more stably, when clamping the workpiece, the staff needs to adjust the positions of the upper slider 11 and the lower slider 12 according to the length of the workpiece, so as to adjust the positions of the first clamping assembly 31 and the second clamping assembly 32, so that the clamping mechanism 3 can clamp workpieces of different lengths.

[0035] In a possible implementation manner, an adjustment mechanism 4 for adjusting the distance between the first clamping assembly 31 and the second clamping assembly 32 is arranged on the frame 1; the adjustment mechanism 4 includes: A first lead screw 41, rotatably connected to the top of the frame 1; the upper slider 11 is in threaded cooperation with the first lead screw 41; the first lead screw 41 is provided with a reverse thread; and A second lead screw 42, rotatably connected to the bottom of the frame 1; the lower slider 12 is in threaded cooperation with the second lead screw 42; the second lead screw 42 is provided with a reverse thread.

[0036] When the first lead screw 41 rotates, it drives the two upper sliders 11 to approach or move away from each other simultaneously, thereby adjusting the distance between the two upper sliders 11. When the second lead screw 42 rotates, it drives the two lower sliders 12 to approach or move away from each other simultaneously, thereby adjusting the distance between the two lower sliders 12. When adjusting the positions of the upper slider 11 and the lower slider 12, it is necessary to ensure that the upper slider 11 is directly above the lower slider 12, so as to ensure that the upper guide roller 313 is directly above the lower guide roller 314.

[0037] In a possible implementation, the adjusting mechanism 4 further includes a driving component 44; the driving component 44 is in transmission connection with the first lead screw 41 and the second lead screw 42, and is used to drive the first lead screw 41 and the second lead screw 42 to rotate synchronously; the driving component 44 includes: A first motor 441, fixedly connected to the frame 1; and A driving shaft 442, rotatably connected to the frame 1; the driving shaft 442 is vertically arranged, and the driving shaft 442 is fixedly connected to the power output shaft of the first motor 441 and is in transmission connection with the first lead screw 41 and the second lead screw 42.

[0038] In a possible implementation, the adjusting mechanism 4 further includes two sets of transmission components 45; the two sets of transmission components 45 are respectively arranged at the connection between the driving shaft 442 and the first lead screw 41 and at the connection between the driving shaft 442 and the second lead screw 42; the transmission component 45 includes: A first bevel gear 451, fixedly connected to the driving shaft 442; and A second bevel gear 452, fixedly connected to the first lead screw 41 or the second lead screw 42; the first bevel gear 451 meshes with the second bevel gear 452.

[0039] When adjusting the positions of the first clamping component 31 and the second clamping component 32, the driving shaft 442 is driven to rotate by the first motor 441. The driving shaft 442 synchronously drives the first lead screw 41 and the second lead screw 42 to rotate through the two sets of transmission components 45, so as to ensure that the upper slider 11 is directly above the lower slider 12 during the process of adjusting the positions of the first clamping component 31 and the second clamping component 32.

[0040] In a possible implementation, the driving mechanism 5 includes: A second motor 51, fixedly connected to the frame 1; and A driving roller 52, rotatably connected to the power output shaft of the second motor 51; the driving roller 52 is arranged on the horizontal side of the workpiece and abuts against the side surface of the workpiece.

[0041] In a possible implementation, the driving mechanism 5 further includes a supporting roller 53 rotatably connected to the frame 1; the supporting roller 53 and the driving roller 52 are respectively arranged on both sides of the workpiece.

[0042] In a possible implementation, the supporting roller 53 and the driving roller 52 have the same structure, and an elastic layer 54 is provided on the outer side surface of the supporting roller 53.

After one end of the workpiece is drilled, the driving mechanism 5 drives the other end of the workpiece to move towards the drilling mechanism 2. At this time, the second clamping assembly 32 or the first clamping assembly 31 is used to clamp and fix the workpiece, and the drilling position of the other end of the workpiece is driven below the drilling mechanism 2 for drilling. During the drilling process, the position of the workpiece is driven by the driving mechanism 5, and different positions of the workpiece are clamped and fixed by the first clamping assembly 31 and the second clamping assembly 32. When drilling at different positions of the workpiece, the position of the workpiece can be moved by the driving mechanism 5, and it is not necessary for the staff to unload and reinstall the workpiece, which improves the drilling efficiency of the mounting workpiece.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
