Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology for cutting beds, and in particular to a double-punching device for cutting beds. Background Technology

[0002] Most automatic cutting machines on the market are equipped with a punching device, usually a single punch. Double or multi-punch devices are rare, which is an area this application aims to improve. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a double punching device for cutting beds, which can automatically and efficiently complete the double punching operation and make needle changing extremely convenient.

[0004] To solve the above technical problems, this utility model provides a double punching device for a cutting bed, including two sets of punching components. The driven gears of the two sets of punching components mesh with the two sides of the motor gear. Under the drive of the motor, the two guide shafts rotate synchronously in opposite directions. One end of each guide shaft is connected to a punching component, and the guide shaft drives the punching component to rotate. The sides of the base plates of the two sets of punching components are respectively connected to a slider, and the slider is slidably connected to the corresponding guide rail. The two sets of guide rails are fixed parallel to each other on a connecting plate. The top of the base plate is connected to the output shaft of a cylinder. Under the drive of the cylinder, the two sets of punching components move up and down synchronously along the guide rail. The two sets of punching components move up and down and rotate to perform drilling and punching.

[0005] The drilling assembly includes two guide assemblies on both sides and a central hole needle assembly. The hole needle assembly has a quick-release structure and a limiting quick-release structure. The base plate of the drilling assembly is L-shaped, and a bearing seat is installed in the central hole of the base plate. One end of the first hole shaft passes through the bearing seat and is connected to the lower end of the coupling. The other end of the first hole shaft is inserted into the fixing hole of the wrench-type drill chuck. The jaws of the wrench-type drill chuck clamp the protruding fulcrum at the top of the drilling needle. This is the quick-release structure of the hole needle assembly. The drilling needle can be quickly disassembled by releasing the jaws of the wrench-type drill chuck. The bottom of the drilling needle is fitted with a guide sleeve and installed in the fixing sleeve, and then screwed into the central hole of the guide post fixing seat. This is the limiting quick-release structure of the hole needle assembly. The drilling needle can be quickly disassembled by loosening the bolt.

[0006] The guide components on both sides have their bottom ends fixed in the ear holes on both sides of the guide post fixing seat. The guide post is covered with an elastic component, and the top end of the guide post passes through the small holes on both sides of the bottom plate of the L-shaped base plate and is connected to the flanged linear bearing.

[0007] The coupling has its upper end connected to the second bore shaft. One end of the guide shaft is fitted into the hollow groove of the second bore shaft. Driven by a cylinder, the guide shaft moves up and down relative to the second bore shaft. The other end of the guide shaft is connected to a driven gear. The driven gear and motor gear are mounted below the mounting base. The motor is mounted on the upper part of the mounting base, and its output shaft is connected to the motor gear. The mounting base is connected to a connecting plate with guide rails. The motor drives the motor gear to rotate, which in turn drives the driven gear to rotate synchronously in the opposite direction. The driven gear drives the two guide shafts to rotate synchronously in the opposite direction. Under the action of the cylinder, the L-shaped base plate drives the guide shaft to move downwards along the axis of the second bore shaft. The two guide shafts, through the lower coupling, drive the first bore shaft and the wrench-type drill chuck to rotate, thereby driving the drilling needle to rotate for drilling. After drilling is completed, under the action of the cylinder, the L-shaped base plate drives the guide shaft to move upwards along the axis of the second bore shaft, and the ejector pin removes the waste material from the drilling needle.

[0008] The outer diameter of the guide shaft is a plane with parallel upper and lower surfaces connected by two arc surfaces on the left and right, and it matches the inner hole shape of the second hole shaft. The upper and lower planes of the guide shaft are fitted and installed in close contact with the two planes of the second hole shaft, and the guide shaft drives the second hole shaft to rotate.

[0009] The two sides of the mounting base are connected to the two side plates of the ejector pin fixing base and are mounted on the top of the mounting base to form a frame structure. The two ejector pins pass through the through holes at the top of the ejector pin fixing base respectively. One end of the ejector pin is fixed to the top plate of the ejector pin fixing base by a fastening component. This is the ejector pin quick release structure. The other end of the ejector pin passes through the guide shaft, the second hole shaft, the coupling, the first hole shaft, the wrench-type drill chuck, the drilling pin, and the hollow groove of the limit quick release structure in sequence. The ejector pin rotates together with the two guide shafts to eject the waste material in the drilling pin.

[0010] The two punching needles can be of the same diameter or different diameters, to complete the operation of punching double holes of different or the same size.

[0011] This utility model double punching device has a quick-release structure for the punching needle assembly, a limiting quick-release structure, and a material ejection needle quick-release structure, which not only guides and limits the punching needle end, but also makes it extremely convenient to change needles.

[0012] The superior effects of this utility model are as follows:

[0013] 1) This utility model double punching device provides automatic and efficient punching when cutting fabric and punching double holes of different sizes. While providing strong penetration, it can quickly and accurately complete the punching operation, and provides extremely high stability and strong adaptability.

[0014] 2) The double punching device of this utility model is more convenient to use than the traditional automatic cutting machine double punching and multi-punching, and the rigidity of the double punching device is strengthened. Attached Figure Description

[0040] like Figure 1 and Figure 2 As shown, this utility model provides a double-punching device for a cutting bed, including two sets of punching components. The double-punching driven gears 7 of the two sets of punching components mesh with the two sides of the double-punching motor gear 6. Under the drive of the motor 31, the two double-punching guide shafts 2 rotate synchronously in opposite directions. One end of each double-punching guide shaft 2 is connected to a punching component, and the double-punching guide shaft 2 drives the punching component to rotate. The sides of the double-punching base plate 12 of the two sets of punching components are respectively connected to the slider 10. The slider 10 is slidably connected to the corresponding miniature linear slide rail 11. The two sets of miniature linear slide rails 11 are fixed parallel to each other on the double-punching connecting plate 32. The top of the double-punching base plate 12 is connected to the output shaft of the cylinder 1. Under the drive of the cylinder 1, the two sets of punching components move up and down synchronously along the miniature linear slide rail 11. The two sets of punching components move up and down and rotate to perform drilling and punching.

[0041] The drilling assembly includes two side guide assemblies and a central hole needle assembly. The hole needle assembly has a quick-release structure and a limiting quick-release structure. The double-drilling base plate 12 of the drilling assembly is L-shaped. A ejector pin drilling bearing seat N9 is installed in the central hole of the double-drilling base plate 12. One end of the double-drilling shaft A14 passes through the ejector pin drilling bearing seat N9 and connects to the lower end of the rigid coupling 8. The other end of the double-drilling shaft A14 is inserted into the fixing hole of the wrench-type drill chuck 15. The jaws of the wrench-type drill chuck 15 clamp the protruding fulcrum at the top of the double-drilling pin 16. This is the quick-release structure of the hole needle assembly (e.g., ...). Figure 2 (As shown in the dashed box), the jaws of the wrench-type drill chuck 15 release to quickly disassemble the double-drilling pin 16; the bottom of the double-drilling pin 16 is fitted with a double-drilling guide sleeve 18, which is then inserted into the double-drilling fixing sleeve 19, and then installed in the middle hole of the double-drilling guide post fixing seat 20. A pin 21 is fitted with a spring 22, which passes through the pin hole, and a locking nut 23 is used to secure it. This is the limiting quick-release structure of the pin assembly (as shown in the dashed box).

The double-drilled guide posts 17 are covered with springs. The top ends of the double-drilled guide posts 17 pass through the small holes on both sides of the bottom plate of the L-shaped double-drilled base plate 12 and are connected to the flanged linear bearing 13.

[0043] The rigid coupling 8 is connected at its upper end to the second bore shaft B5. One end of the guide shaft 2 is fitted into the hollow groove of the second bore shaft B5.

The motor 31 is installed on the upper part of the double-drilled mounting base 4 and the motor output shaft is connected to the double-drilled motor gear 6. The double-drilled mounting base 4 is connected to the double-drilled connecting plate 32 equipped with the miniature linear slide rail 11. Motor 31 drives the double-drilling motor gear 6 to rotate, which in turn drives the double-drilling driven gear 7 to rotate synchronously in opposite directions. The double-drilling driven gear 7 drives the two double-drilling guide shafts 2 to rotate synchronously in opposite directions. Under the action of cylinder 1, the L-shaped double-drilling base plate 12 drives the double-drilling guide shafts 2 to move downward along the axis of the double-drilling shaft B5. The two double-drilling guide shafts 2 drive the double-drilling shaft A14 and the wrench-type drill chuck 15 to rotate through the lower rigid coupling 8, thereby driving the double-drilling needle 16 to rotate for drilling. After drilling is completed, under the action of cylinder 1, the L-shaped double-drilling base plate 12 drives the double-drilling guide shafts 2 to move upward along the axis of the double-drilling shaft B5, and the ejector pin 25 ejects the waste material from the double-drilling needle 16.
