Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a copper tube cutting equipment for refrigeration and air conditioning processing. Background Art

[0002] Refrigeration air conditioning is used for indoor cooling, which can reduce the temperature indoors on hot summer days, making people working indoors more comfortable and increasing their work efficiency.

[0003] However, the copper tubes used in different types of air conditioners have different specifications. When cutting the copper tubes, the specifications of the clamping device of the cutting equipment are limited, and only copper tubes of the same specification can be clamped, so different types of cutting devices must be used, increasing the workload. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a copper tube cutting device for refrigeration and air conditioning processing, which overcomes the shortcomings of the prior art and effectively solves the problem that the specifications of the clamping device of the cutting equipment in the prior art are limited and can only clamp copper tubes of the same specification, thereby requiring the use of different types of cutting devices, increasing the workload.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A copper tube cutting device for refrigeration and air conditioning processing, comprising a base plate, the inner walls at both ends of the base plate are rotatably connected to a first screw, and the rod wall of the first screw is screwed to a first T-shaped plate, the top two ends of the base plate are fixed with clamping mechanisms, and symmetrically distributed support blocks are arranged between the two clamping mechanisms, a fixing frame is fixed to one side of the top of the base plate, and the inner walls at both ends of the fixing frame are rotatably connected to a second screw, the rod wall of the second screw is screwed to a cutting mechanism, the clamping mechanism comprises a support frame, a bidirectional screw rotatably connected to the inner walls at both ends of the support frame, and a second T-shaped plate screwed to both ends of the rod wall of the bidirectional screw, and the cutting mechanism comprises a mounting plate, a cutter fixed to the bottom of the mounting plate, and a pre-pressing component fixed to the outer walls on both sides of the mounting plate.

[0007] The copper tube is placed on the top of two support blocks and two support frames, and the rotation of the bidirectional lead screw drives the two second T-shaped plates to approach each other to limit and clamp the two sides of the copper tube, and the first servo motor drives the first screw to rotate, and then adjusts the position of the first T-shaped plate, so that one end of the copper tube abuts against the first T-shaped plate, thereby determining the cutting length of the copper tube, and the second servo motor drives the second screw to rotate, and then drives the cutting mechanism to move downward. As the cutting mechanism moves downward, the longer pre-pressing component first cuts the copper tube, and the pre-pressing component and the support block cooperate with each other to clamp and fix the copper tube, so that the copper tube remains stable during the cutting process.

[0008] Preferably, a first servo motor is installed at one end of the base plate, and the output shaft of the first servo motor is connected and fixed to the first screw rod, and the first T-shaped plate forms a sliding fit with the base plate.

[0009] The first servo motor drives the first screw rod to rotate, thereby adjusting the position of the first T-shaped plate, so that copper tubes of different lengths can be cut.

[0010] Preferably, a second servo motor is installed at the top end of the fixing frame, and the output shaft of the second servo motor is connected and fixed to the top end of the second screw rod.

[0011] The second servo motor drives the second screw to rotate, thereby driving the cutting mechanism to adjust the height position.

[0012] Preferably, the bottom of the support frame is connected and fixed to the top of the bottom plate, and the second T-shaped plate forms a sliding fit with the support frame.

[0013] The copper tube is placed and supported by a support frame, and two second T-shaped plates are used to limit and clamp the two sides of the copper tube.

[0014] Preferably, a screw hole matched with the second screw rod is opened at one end of the top of the mounting plate, and the mounting plate and the fixing frame form a sliding fit.

[0015] The rotating second screw drives the screwed mounting plate to move up and down along the fixing frame.

[0016] Preferably, the pre-pressing assembly comprises a T-shaped block, a plug rod plugged into the two ends of the top of the T-shaped block, and a pressure block fixed to the bottom end of the plug rod by a telescopic spring sleeved on the wall of the plug rod.

[0017] As the cutting mechanism moves downward, the longer pre-pressing component cutter contacts the copper tube first, and the pre-pressing component and the support block cooperate with each other to clamp and fix the copper tube, so that the copper tube remains stable during the cutting process.

[0018] Preferably, a limiting block is fixed on the top of the insertion rod, and a buffer pad is fixed on the bottom of the pressing block.

[0019] The limit block can prevent the insertion rod and the T-block from detaching from each other, and the buffer pad can prevent the pressure block from causing damage to the outer wall of the copper tube.

[0020] The beneficial effects of the utility model are:

[0021] By placing the copper tube on top of two support blocks and two support frames, the two second T-plates are driven by a bidirectional screw rod to approach each other to limit and clamp the two sides of the copper tube, and by adjusting the position of the first T-plate, one end of the copper tube is abutted against the first T-plate, thereby determining the cutting length of the copper tube. As the cutting mechanism moves downward, the longer pre-pressing component first contacts the copper tube, and the pre-pressing component and the support blocks cooperate with each other to clamp and fix the copper tube, so that the copper tube remains stable during the cutting process. This effectively solves the problem in the prior art that the specifications of the clamping device of the cutting equipment are limited and can only clamp copper tubes of the same specification, thereby requiring the use of different types of cutting devices and increasing the workload.
