Description

Technical Field

[0001] The invention belongs to the technical field of tie rod punching, and in particular relates to a metal tube laser punching device for tie rod production. Background Art

[0002] The tie rod hole of a suitcase is an indispensable and important part of the suitcase. The tie rod hole allows the tie rod to be firmly inserted and fixed inside the suitcase. The tie rod hole allows the tie rod to be fixed in multiple positions to achieve length adjustment. The tie rod hole also plays a role in fixing the tie rod to ensure that the tie rod will not fall off or shake during the movement of the suitcase, thereby maintaining the stability and safety of the suitcase. Therefore, when producing the tie rod of the suitcase, it is necessary to punch multiple small holes on the tie rod, and when punching the tie rod of the suitcase, it is necessary to punch holes on two opposite side walls.

[0003] A Chinese patent with the authorization announcement number CN213105507U discloses a square tube punching device, a workbench, a placement plate, a clamping device, a drilling device, an adjusting device, and a flipping device. By arranging the clamping device on the workbench, the square tube to be processed can be firmly clamped, and the first cylinder drives the moving clamping plate to move, so that the clamping device can be applied to the processing of square tubes of various sizes.

[0004] Existing tie rod tube punching devices usually clamp and fix the tie rod tube externally. Since the luggage case tie rod is generally made of all-aluminum or aluminum alloy, the hardness of the aluminum tie rod tube is relatively low. The temperature of the tie rod tube will rise during laser punching, which is more likely to cause deformation. When the existing punching device is punching a hole in the tie rod tube, the clamping mechanism causes the tie rod tube to bend or twist due to the increase in the temperature of the tie rod tube during punching, thereby affecting the quality of the tie rod tube. Summary of the invention

[0005] The purpose of the present invention is to provide a metal tube laser drilling device for tie rod production, aiming to solve the problem in the prior art that the clamping mechanism of the drilling device causes the tie rod tube to bend or twist due to the increase in the temperature of the tie rod tube during drilling.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal tube laser drilling device for pull rod production, comprising a base, an external clamping mechanism, a drilling mechanism and an internal clamping mechanism located on the top of the base.

[0007] The internal clamping mechanism includes a support plate, a mounting turntable rotatably sleeved on the support plate, a driving member for driving the mounting turntable to rotate, two inner clamping plates vertically arranged on the mounting turntable and radially sliding along the mounting turntable, and a driving assembly for driving the two inner clamping plates to move away from each other and support and clamp the inner wall of the pull rod. Two connecting plates slidably sleeved on each other are provided between the two inner clamping plates, and the two connecting plates are respectively fixedly mounted on the middle of the outer walls of the two inner clamping plates.

[0008] The driving assembly includes a supporting telescopic rod, a slider and a transmission rod fixedly mounted on a turntable. An adjusting slide groove is opened on the mounting turntable along its radial direction. There are two sliders and both are mounted in the adjusting slide groove along the radial direction of the mounting turntable for sliding. One end of the two inner clamps is respectively connected to the two sliders. There are two transmission rods and both are located between the two sliders. One end of the two transmission rods is respectively hinged to the two sliders.

[0009] The effect is that the inner and outer walls of the tie rod can be supported and clamped at the same time, so that the tube wall of the tie rod can be supported and strengthened, and deformation such as bending or twisting of the tie rod caused by the increase in the temperature of the tie rod tube during drilling is avoided.

[0010] The bottom and top of the adjusting slide groove are provided with limit slide grooves, the limit slide grooves are perpendicular to the axis of the mounting turntable, and the top and bottom of the sliding block are fixedly installed with limit blocks which are slidably sleeved in the limit slide grooves.

[0011] The effect is that the movement of the slider can be limited so that the slider can only slide along the length direction of the limiting slide groove, ensuring that the two inner clamping plates can smoothly fix and clamp the inner wall of the pull rod.

[0012] The driving member comprises a motor mounted on the mounting turntable, the output shaft of the motor rotates through the mounting turntable and is fixedly mounted with a gear, a gear ring is fixedly mounted on the outer wall of the mounting turntable, and the gear ring and the gear are meshed with each other.

[0013] The effect is that the pull rod can be flipped while being clamped by the inner clamping mechanism, thereby avoiding the need to reposition the pull rod drilling hole after flipping, and ensuring the accuracy of the pull rod drilling position.

[0014] There are two support plates symmetrically arranged on the left and right sides of the top of the base, one of the support plates is fixedly installed at one end of the top of the base, and the other support plate is movably installed at the other end of the top of the base. The inner clamping plate is located between the two support plates, and support shafts are fixedly installed at both ends of the inner clamping plate. A connecting hole is provided at one end of the slider close to the inner clamping plate, and the support shaft is slidably sleeved in the connecting hole on the slider. An adjusting mechanism is provided on the top of the base for adjusting the position of the support plate movably installed on the top of the base.

[0015] The adjusting mechanism comprises an adjusting block located on the top of the base, an adjusting telescopic rod installed on the adjusting block for driving the supporting plate to move, and a hydraulic telescopic rod for driving the adjusting block to move along the front-rear direction of the base.

[0016] The effect is that the two support plates are provided, which can improve the stability of the clamping in the pull rod, and at the same time the position of one of the support plates can be adjusted, which is convenient for loading and unloading when drilling holes in the pull rod.

[0017] The outer clamping mechanism comprises two fixed blocks symmetrically arranged at the front and rear sides of the top of the base and a clamping telescopic rod installed on the fixed blocks and telescopic along the front and rear directions. The telescopic end of the clamping telescopic rod is fixedly installed with an outer clamping plate.

[0018] The drilling mechanism comprises a lifting telescopic rod located on the top of the base and sliding in the left and right directions and a support rod installed at the telescopic end of the lifting telescopic rod. One end of the support rod is located on the top of the inner clamping plate and is equipped with a laser puncher.

[0019] The base includes a bottom plate and supporting legs for supporting the bottom plate. A lifting telescopic rod is provided in the middle of the bottom end of the bottom plate. The telescopic end of the lifting telescopic rod passes through the bottom plate and is fixedly installed with a supporting plate for lifting the pull rod.

[0020] The top and bottom of the two inner clamps are fixedly installed with a material baffle plate, which is located between the two inner clamps. The material baffle plate is an L-shaped plate. The material baffle plate, the inner clamps and the connecting plate form a semi-closed through groove for collecting waste chips generated by punching. The top and bottom of the connecting plate are slidably installed with a cleaning plate for pushing out the waste chips collected in the through groove.

[0021] The effect is that the waste chips from drilling can be cleaned, thereby preventing the waste chips from remaining in the internal clamping mechanism.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] By providing an inner clamping mechanism and an outer clamping mechanism, the inner and outer walls of the tie rod can be supported and clamped simultaneously, thereby supporting and strengthening the tube wall of the tie rod, and avoiding deformation such as bending or twisting of the tie rod due to increased temperature of the tie rod tube during drilling.

[0046] The implementation principle of the embodiment of the present invention is: when drilling the tie rod, the tie rod tube 6 is sleeved on the two inner clamping plates 24, and the telescopic rod 12 is started to push out its telescopic end and drive the support plate to rise, so that the support plate can support the tie rod tube 6.

[0047] Start the hydraulic telescopic rod so that its telescopic end begins to extend and retract and drives the adjusting block 31 to move along the front-rear direction of the base 1, thereby adjusting the position of the support plate 21 movably mounted on the top of the base 1, so that the support plate 21 is symmetrical with another support plate 21 fixedly mounted on the top of the base 1, and then start the adjusting telescopic rod 32 to drive the support plate 21 movably mounted on the top of the base 1 to move toward the other support plate 21 fixedly mounted on the top of the base 1, until the support plate 21 movably mounted on the top of the base 1 contacts the inner clamping plate 24, at which time the support shaft 242 on the inner clamping plate 24 is slidably sleeved into the connecting hole 261 on the slider 26.

[0048] Start the supporting telescopic rod 25 to push out its telescopic end.

After the drilling of the upper surface is completed, start the clamping telescopic rod 42 to retract its telescopic end and drive the outer clamping plate 43 away from the tie rod tube 6. Start the motor to drive the gear to rotate. Through the mutual engagement of the gear and the gear ring, drive the mounting turntable 22 to rotate, thereby completing the flipping of the tie rod tube 6. Then start the clamping telescopic rod 42 again to extend its telescopic end and drive the outer clamping plate 43 to move toward the tie rod tube 6, thereby externally clamping the tie rod tube 6, and control the drilling mechanism 5 to drill a hole in the tie rod tube 6.

[0050] After the drilling is completed, the inner clamping mechanism 2, the adjusting mechanism 3 and the outer clamping mechanism 4 are controlled to reset, and then the pull rod tube 6 is removed from the inner clamping plate 24, and the cleaning plate 28 is pushed to move along the inner clamping plate 24. The cleaning plate 28 pushes out the drilling waste that falls into the through groove due to the flipping of the pull rod tube 6 and cleans the waste.
