Description

Technical Field

[0001] This utility model relates to the technical field of positioning devices for CNC pipe bending machines, and in particular to a positioning device for CNC pipe bending machines. Background Technology

[0002] CNC pipe bending machines are specialized equipment for bending metal pipes. They are widely used in aerospace, automotive, locomotive, shipbuilding, petrochemical, power, natural gas, nuclear industry, boiler, vehicle, fitness equipment, air conditioning and refrigeration, sporting goods and other fields. This machine can perform single or double bending radius winding bending on pipes in a cold state and is suitable for bending various pipes and wires.

[0003] CNC pipe bending machines require positioning devices during the pipe bending process. Traditional positioning devices mostly use two clamping plates to clamp and fix the pipe, lacking multi-point clamping design. This causes the pipe to easily shift when a bending moment is applied, affecting the processing accuracy. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a positioning device for a CNC pipe bending machine.

[0005] This utility model is achieved by the following technical solution: a positioning device for a CNC pipe bending machine, including a worktable, a positioning component is provided at the upper end of the worktable, a control panel is fixedly connected to the front end of the worktable, and a base is fixedly connected to the bottom of the worktable.

[0006] The positioning component includes a fixed frame, a hydraulic telescopic rod fixedly connected to the bottom of the inner wall of the fixed frame, a fixed plate fixedly connected to the output end of the hydraulic telescopic rod, a first hinge fixedly connected to the upper surface of the fixed plate, a connecting plate hinged to the inner wall of the first hinge, a second hinge hinged to the end of the connecting plate away from the first hinge, a clamping plate fixedly connected to the top of the second hinge, a vertical plate fixedly connected to the top of the fixed frame, and a support rod fixedly connected to one end of the vertical plate.

[0007] Through the above technical solution, the output end of the hydraulic telescopic rod pulls the fixed plate downward, causing the first hinge to move downward, so that the two ends of the connecting plate rotate on the inner walls of the first and second hinges, thereby pulling the clamping plates closer to each other. The pipe is clamped and fixed by the four clamping plates, and the pipe is clamped at multiple points to ensure the stability of the pipe during processing and avoid displacement due to bending moment, thereby ensuring processing accuracy. When the output end of the hydraulic telescopic rod pushes upward, the clamping plates move away from each other, thereby canceling the clamping and fixing of the pipe.

[0008] As a further improvement to the above solution, a limiting groove is provided on the inner wall of the fixed frame, and the two ends of the fixed plate are slidably connected to the inner wall of the limiting groove.

[0009] The above technical solution limits the two ends of the fixed plate by using the limiting groove, making the fixed plate more stable when moving up and down and preventing the fixed plate from tilting when moving.

[0010] As a further improvement to the above solution, the inner wall of the clamping plate is slidably connected to the surface of the support rod, and four clamping plates are provided, which are symmetrically distributed around the fixed frame.

[0011] The above technical solution uses a support rod to limit the clamping plate, allowing the clamping plate to slide smoothly along the support rod in a straight line.

[0012] As a further improvement to the above solution, a mounting plate is fixedly connected to the right end of the workbench, and a motor is fixedly connected to the upper end of the mounting plate.

[0013] As a further improvement to the above solution, a lead screw is fixedly connected to the output end of the motor, and the surface of the lead screw is rotatably connected to the inner wall of the worktable.

[0014] The above technical solution uses a motor to drive a lead screw to rotate, which in turn causes the mounting base to move back and forth.

[0015] As a further improvement to the above solution, the surface of the lead screw is threaded with a mounting base, the top of the mounting base is fixedly connected to the bottom of the fixed frame, and a limit rod is slidably connected to the inner wall of the mounting base.

[0016] With the above technical solution, when the mounting base moves, it will drive the fixed frame to move, thereby moving the clamped and fixed pipe, which can adjust the bending position of the pipe and improve the flexibility during use.

[0017] As a further improvement to the above solution, the two ends of the limiting rod are fixedly connected to the inner wall of the worktable, and there are two limiting rods, which are symmetrically distributed with the mounting base as the center.

[0018] The above technical solution uses a limiting rod to limit the position of the mounting base, ensuring its stability and support capacity during movement.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model, by setting up a positioning component, specifically by activating a hydraulic telescopic rod, pulls the fixed plate downwards at its output end, causing the first hinge to move downwards. This causes the two ends of the connecting plate to rotate on the inner walls of the first and second hinges, thereby pulling the clamping plates closer together. The pipe is clamped and fixed by the four clamping plates, implementing multi-point clamping of the pipe, effectively preventing pipe displacement during processing, and ensuring processing accuracy and quality.

[0021] This utility model incorporates a motor, a lead screw, and a mounting base. Specifically, starting the motor causes the lead screw to rotate, which in turn moves the mounting base and the fixing frame, causing the fixed pipe to move back and forth. This allows for easy adjustment of the pipe's position according to processing requirements, improving flexibility during use. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5A positioning device for a CNC pipe bending machine according to this embodiment includes a worktable 1, a positioning component 2 is provided at the upper end of the worktable 1, a control panel 3 is fixedly connected to the front end of the worktable 1, and a base 4 is fixedly connected to the bottom of the worktable 1.

[0032] The positioning component 2 includes a fixed frame 201. A hydraulic telescopic rod 202 is fixedly connected to the bottom of the inner wall of the fixed frame 201. A fixed plate 203 is fixedly connected to the output end of the hydraulic telescopic rod 202. A first hinge 204 is fixedly connected to the upper surface of the fixed plate 203. A connecting plate 205 is hinged to the inner wall of the first hinge 204. A second hinge 206 is hinged to the end of the connecting plate 205 away from the first hinge 204. A clamping plate 207 is fixedly connected to the top of the second hinge 206. A vertical plate 208 is fixedly connected to the top of the fixed frame 201. A support rod 209 is fixedly connected to one end of the upright plate 208. When the hydraulic telescopic rod 202 is activated, the output end of the hydraulic telescopic rod 202 pulls the fixed plate 203 downward, which in turn moves the first hinge 204 downward. This causes the two ends of the connecting plate 205 to rotate on the inner walls of the first hinge 204 and the second hinge 206, thereby pulling the clamping plates 207 closer together. The pipe is clamped and fixed by the four clamping plates 207, and the pipe is clamped at multiple points, which effectively prevents the pipe from shifting during the processing and ensures the accuracy and quality of the processing.

[0033] The inner wall of the fixed frame 201 is provided with a limiting groove 5, and the two ends of the fixed plate 203 are slidably connected to the inner wall of the limiting groove 5.

[0034] The inner wall of the clamping plate 207 is slidably connected to the surface of the support rod 209. There are four clamping plates 207, which are symmetrically distributed around the fixed frame 201.

[0035] A mounting plate 6 is fixedly connected to the right end of the workbench 1, and a motor 7 is fixedly connected to the upper end of the mounting plate 6.

[0036] The output end of the motor 7 is fixedly connected to a lead screw 8, and the surface of the lead screw 8 is rotatably connected to the inner wall of the worktable 1.

[0037] The screw 8 is threadedly connected to a mounting base 9. The top of the mounting base 9 is fixedly connected to the bottom of the fixed frame 201. The inner wall of the mounting base 9 is slidably connected to a limit rod 10. When the motor 7 is started, the motor 7 drives the screw 8 to rotate, causing the mounting base 9 to move. At the same time, the fixed frame 201 moves, causing the fixed pipe to move back and forth. This allows the pipe position to be adjusted according to processing requirements, improving the flexibility of use.

[0038] The two ends of the limiting rod 10 are fixedly connected to the inner wall of the worktable 1. There are two limiting rods 10, which are symmetrically distributed with the mounting base 9 as the center.

[0039] The implementation principle of a positioning device for a CNC pipe bending machine in this embodiment is as follows: During use, the pipe is placed on the upper end of the fixed frame 201. Then, the hydraulic telescopic rod 202 is activated. The output end of the hydraulic telescopic rod 202 pulls the fixed plate 203 downwards, causing the first hinge 204 to move downwards. This causes the two ends of the connecting plate 205 to rotate on the inner walls of the first hinge 204 and the second hinge 206, thereby pulling the clamping plates 207 closer together. The pipe is clamped and fixed by the four clamping plates 207, implementing multi-point clamping to effectively prevent pipe displacement during processing, ensuring processing accuracy and quality. The motor 7 is activated, driving the lead screw 8 to rotate, causing the mounting base 9 to move. Simultaneously, the fixed frame 201 moves, causing the fixed pipe to move back and forth, facilitating adjustment of the pipe position according to processing requirements and improving flexibility during use.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
