Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a drill rod drive mechanism for a punching device for a cutting bed. Background Technology

[0002] As the types of fabrics used in cutting beds increase, the specifications of cut pieces also become more diverse. Some cut pieces not only require high precision in cutting dimensions, but also need to be perforated. In addition, the same cut piece sometimes needs to be processed with multiple hole types. To adapt to the processing requirements of various perforation specifications, there are now structures that use a rotary table with multiple perforating drills of different sizes, and the rotation of the rotary table allows for the switching of different types of perforating drills.

[0003] However, in practical applications, a suitable drive structure is required to drive the drilling drill to rotate and press down smoothly to drill holes in the fabric. However, the rotary table needs to rotate periodically to switch the drilling drill, which makes it difficult to maintain a stable and smooth drive for the drilling drill and the rotation switching of the rotary table, thus easily affecting the reliability and efficiency of the equipment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a drill rod drive mechanism for a cutting bed drilling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drill rod drive mechanism for a cutting bed drilling device includes: a rotary table rotatably mounted on a frame; multiple hollow drills of different specifications are evenly distributed circumferentially on the rotary table, and drill rods are connected to the hollow drills accordingly; the drill rods are rotated and drive the hollow drills to rotate; a drill rod top plate is provided on the drill rod; a washer is fixed on the frame; the washer has a notch and a lifting clamp plate that is lifted and lowered within the notch; the drill rod top plate can slide against the washer or the lifting clamp plate; the lifting clamp plate drives the drill rod and the hollow drills to move up and down through the drill rod top plate.

[0007] Preferably, the lifting clamping plate includes a lower plate flush with the upper end face of the pad ring and an upper plate located above the lower plate, the lower plate and the upper plate forming a clamping groove into which the drill rod top plate slides.

[0008] Preferably, the frame is provided with a lifting frame for the lifting clamp to slide up and down, and the lifting frame is driven to slide up and down along the lifting frame.

[0009] Preferably, a lifting cylinder is installed on the frame, and the driving end of the lifting cylinder is connected to the lifting clamp plate and drives the lifting clamp plate to slide up and down along the lifting frame.

[0010] Preferably, the rotary table is provided with a driven tooth that is driven to rotate and driven teeth distributed on the outer periphery of the driven tooth and meshing with it. The outer periphery of the drill rod is provided with a drill rod sleeve that is slidably connected up and down by a sliding key. The drill rod sleeve is fixed on the driven tooth.

[0011] Preferably, a drive motor is mounted on the frame, and the drive end of the drive motor is connected to the driving tooth and drives the driving tooth to rotate.

[0012] Preferably, a pressure block is slidably connected to the lower end of the hollow drill, and the pressure block is provided with a slide rod that is slidably inserted into the rotary table. The pressure block can slide up and down relative to the hollow drill and is connected to the rotary table.

[0013] Preferably, a ejector pin is slidably inserted into the drill rod and the hollow drill, and a ejector pin seat for fixing the ejector pin is provided on the rotary table.

[0014] Preferably, a gear ring is fixed on the outer periphery of the rotary disk, and a gear that drives the rotary disk to rotate is meshed on the gear ring. The gear is connected to the drive end of the rotary motor.

[0015] Preferably, the hollow drill is detachably mounted on the drill rod via a quick-change chuck.

[0016] The beneficial effects of this utility model are:

[0017] 1. The drill rod and hollow drill are abutted against the washer ring by the drill rod top plate, and a lifting clamp plate that can be raised and lowered is set at the notch of the washer ring. Then, hollow drills of different specifications can slide and switch on the washer ring or the lifting clamp plate by the drill rod top plate. When the drill rod top plate of one of the hollow drills slides to the lifting clamp plate, the lifting clamp plate can be raised and lowered and drive the drill rod and hollow drill to move up and down, thereby realizing the flexible, stable, smooth and reliable switching of hollow drills and the efficient control of downward drilling operations, effectively improving the overall efficiency of drilling operations.

[0018] 2. A pin holder with a fixed pin is provided on the rotary table. When the drill rod and the hollow drill rotate and press down to perform drilling, the pin can slide upward relative to the hollow drill. When the drilling operation is completed and the drill rod and the hollow drill move upward and reset, the pin can slide downward relative to the hollow drill. This realizes the automatic ejection of waste cloth from the hole in the hollow drill by the pin, thereby improving the automation level of the equipment and ensuring that the equipment can operate and process continuously and reliably.

[0019] 3. A pressure block is slidably connected to the lower end of the hollow drill. When the hollow drill is drilling, the pressure block can press down and fix the fabric to be drilled, so that the hollow drill can rotate and drill the fabric more stably and reliably. Furthermore, slide rods are connected to both sides of the pressure block and slidably inserted into the rotary table. The slide rods prevent the lower end of the hollow drill from shaking during rotation, thereby ensuring the drilling quality of the hollow drill. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0032] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Example 1:

[0034] like Figures 6-10 As shown, this embodiment discloses a drill rod drive mechanism for a cutting bed drilling device, including: a rotary disk 2, which is rotatably mounted on a frame 1. Specifically, a rotary motor 16 is mounted on the frame 1, and a gear ring 26 is fixed on the outer periphery of the rotary disk 2. A gear 161 that drives the rotary disk 2 to rotate is meshed on the gear ring 26. The gear 161 is connected to the drive end of the rotary motor 16, and the rotary motor 16 drives the rotary disk 2 to rotate through the gear 161 and the gear ring 26.

[0035] The rotary table 2 is circumferentially distributed with multiple hollow drills 22 of different specifications and drill rods 21 connected to the hollow drills 22. The hollow drills 22 of different specifications can be used to drill holes in the fabric to process different hole shapes. It can also be understood that the rotary table 2 is equipped with drill rods 21 connected to the hollow drills 22. The hollow drills 22 are detachably installed on the drill rods 21 through quick-change chucks 221, and the hollow drills 22 can be quickly disassembled and replaced through quick-change chucks 221 (for the structure of the quick-change chuck 221, please refer to the Chinese utility model patent with patent number: 202421308593.3, patent name: a quick-change device for replacing hollow drills).

[0036] By rotating the rotary table 2, hollow drills 22 of different specifications and hole types are distributed circumferentially. Rotating the rotary table 2 drives the hollow drills 22 on it to rotate, thereby selecting the hollow drill 22 with the required hole type for the operation. By switching between the hollow drills 22 of different specifications, the drilling needs of various specifications of fabric can be met, effectively improving the processing efficiency and applicability of fabric drilling operations.

[0037] The rotary motor 16 can be a servo motor, which can precisely control the rotation angle of the rotary table 2 so as to rotate and displace the hollow drill 22 of the required specifications to a suitable position. Specifically, the drill rod 21 is provided with a drill rod top plate 23, and the frame 1 is fixed with a washer 231. The washer 231 is provided with a notch and a lifting clamping plate 11 that is lifted and lowered in the notch. The rotary table 2 rotates to drive the drill rod 21 to rotate circumferentially, so that the drill rod top plate 23 can slide against the washer 231 or the lifting clamping plate 11. When the drill rod top plate 23 of the hollow drill 22 of the required specifications rotates and displaces to the lifting clamping plate 11, the lifting clamping plate 11 can drive the drill rod 21 and the hollow drill 22 to move up and down through the drill rod top plate 23.

[0038] The lifting clamp 11 includes a lower plate 111 flush with the upper end face of the washer 231 and an upper plate 112 located above the lower plate 111. When the drill rod top plate 23 rotates circumferentially with the rotary table 2, the drill rod top plate 23 can slide between the upper end face of the washer 231 and the upper end face of the upper plate 112. Furthermore, by setting the upper end face of the washer 231 flush with the upper end face of the lower plate 111, the drill rod top plate 23 can slide more smoothly on the lifting clamp 11 and the washer 231 to switch displacements.

[0039] The lower plate 111 and the upper plate 112 form a clamping groove 113 into which the drill rod top plate 23 slides. The frame 1 is provided with a lifting frame 12 for the lifting clamping plate 11 to slide up and down. The lifting frame 12 is driven to slide up and down. When the drill rod top plate 23 slides into the clamping groove 113, the lifting clamping plate 11 can be driven to slide up and down along the lifting frame 12, so as to drive the drill rod 21 and the hollow drill 22 to move up and down through the drill rod top plate 23.

[0040] Furthermore, a lifting cylinder 13 is installed on the frame 1. The driving end of the lifting cylinder 13 is connected to the lifting clamp 11 and drives the lifting clamp 11 to slide up and down along the lifting frame 12. Thus, hollow drills 22 of various specifications can slide and switch on the pad ring 231 or the lifting clamp 11 through the drill rod top plate 23. When the drill rod top plate 23 on one of the hollow drills 22 slides to the lifting clamp 11, the lifting clamp 11 can rise and fall and drive the drill rod 21 and the hollow drill 22 to rise and fall, thereby realizing the flexible, stable, smooth and reliable switching of the hollow drill 22 and the efficient control of downward drilling operation, effectively improving the overall efficiency of drilling operation.

[0041] The drill rod 21 is driven to rotate and drives the hollow drill 22 to rotate and drill holes. Specifically, the rotary table 2 is provided with a driven tooth 252 that is driven to rotate and driven teeth 212 distributed on the outer periphery of the driven tooth 252 and meshing with it. The driven tooth 252 is located at the center of the rotary table 2, and multiple driven teeth 212 are distributed on the outer periphery of the driven tooth 252. The driven tooth 252 and the driven teeth 212 adopt a planetary layout transmission to effectively reduce the design space of the equipment.

[0042] A drive motor 25 is mounted on the frame 1. The drive end of the drive motor 25 is connected to the drive gear 252 and drives the drive gear 252 to rotate the driven gear 212.

[0043] Furthermore, the drill rod 21 is provided with a drill rod sleeve 211 on its outer periphery, which is connected to the drill rod 21 by sliding key. That is, the drill rod 21 can slide up and down relative to the drill rod sleeve 211 by sliding key, and the drill rod sleeve 211 can drive the drill rod 21 to rotate circumferentially. Thus, the up and down movement and circumferential rotation are performed by sliding key, making the transmission control of the drill rod 21 smoother and more reliable.

[0044] The drill rod sleeve 211 is fixed on the driven tooth 212, and then the drill rod 21 and the hollow drill 22 connected to the drill rod 21 are driven to rotate through the driving tooth 252, the driven tooth 212, and the drill rod sleeve 211, so as to drive the hollow drill 22 to rotate and press down to drill a hole.

[0045] To ensure the reliability of the drilling process in this embodiment, a ejector pin 24 is slidably inserted into the drill rod 21 and the hollow drill 22. The ejector pin 24 can slide relative to the drill rod 21 and the hollow drill 22. The rotary table 2 is provided with an ejector pin seat 241 for fixing the ejector pin 24. The ejector pin 24 rotates synchronously with the drill rod 21 and the hollow drill 22 through the ejector pin seat 241.

[0046] When the drill rod 21 and the hollow drill 22 are rotating and pressing down to perform drilling, the ejector pin 24 can slide upward relative to the hollow drill 22. When the drilling operation is completed and the drill rod 21 and the hollow drill 22 are moved upward and reset, the ejector pin 24 can slide downward relative to the hollow drill 22. This enables the ejector pin 24 to automatically eject the waste cloth in the hole of the hollow drill 22, thereby improving the automation level of the equipment and ensuring that the equipment can operate continuously and reliably.

[0047] The lower end of the hollow drill 22 is provided with a pressure block 28 that can slide up and down on the rotary table 2. That is, the lower end of the hollow drill 22 is slidably connected to the pressure block 28. The hollow drill 22 can penetrate the pressure block 28 downward and rotate downward to drill holes. That is, when the hollow drill 22 is drilling, the pressure block 28 can first press down and fix the fabric to be drilled, so that the rotation and drilling operation of the hollow drill 22 on the fabric can be more stable and reliable.

[0048] Furthermore, the pressure block 28 is provided with a sliding rod 281 that is slidably inserted into the rotary table 2. The sliding rod 281 is distributed on both sides of the pressure block 28. The pressure block 28 can slide up and down relative to the hollow drill 22 on the rotary table 2. By connecting the sliding rod 281 that is slidably inserted into the rotary table 2 on both sides of the pressure block 28, the lower end of the hollow drill is prevented from shaking during rotation, thereby ensuring the drilling quality of the hollow drill 22.

[0049] like Figures 1-10 As shown, this embodiment also discloses a drilling device for a cutting bed, including the above-mentioned drill rod drive mechanism. A lever seat 15 and a pin sleeve 32 are fixed on the frame 1. The pin sleeve 32 is arranged opposite to the lever seat 15. It can also be understood that the pin sleeve 32 and the lever seat 15 are fixedly arranged adjacent to each other on the frame 1.

[0050] Specifically, the lever seat 15 is provided with a rotatable lever plate 34 and a top plate 141 that can abut against and drive the lever plate 34 to rotate and press against the positioning pin 3. The top plate 141 is slidably disposed in the lever seat 15. The top plate 141 is provided with a pressing part 142 that can press against and drive the lever plate 34 to rotate, so as to press the lever plate 34 to rotate and press against the positioning pin 3.

[0051] The frame 1 is provided with a positioning cylinder 14, and the top plate 141 is connected to the positioning cylinder 14. That is, the driving end of the positioning cylinder 14 is connected to the top plate 141 and drives the pressing part 142 to slide and press against the lever plate 34, thereby enabling the lever plate 34 to rotate and press against the positioning pin 3 on its other end.

[0052] Furthermore, the positioning pin 3 is slidably disposed within the pin sleeve 32 and both ends of the positioning pin 3 can penetrate outward through the pin sleeve 32. It can also be understood that the pin sleeve 32 is provided with a positioning pin 3 that can slide through both ends of it. One end of the positioning pin 3 penetrates outward through the pin sleeve 32 and abuts against the lever plate 34. That is, one end of the positioning pin 3 penetrates outward through the pin sleeve 32 and abuts against one end of the lever plate 34, and the top plate 141 slides against the other end of the lever plate 34.

[0053] The lever plate 34 is provided with a rotating shaft 341 rotatably mounted on the lever seat 15. The two ends of the lever plate 34 are rotatably abutted against the positioning pin 3 and the top plate 141 through the rotating shaft 341.

[0054] The outer periphery of the rotary table 2 is provided with a pin hole 27 corresponding to the position of the hollow drill 22 and adapted to the positioning pin 3. That is, when the positioning pin 3 is inserted into the pin hole 27, the corresponding hollow drill 22 can be moved up and down by the lifting clamp 11. The positioning pin 3 is driven to be inserted into the pin hole 27 to position the hollow drill 22 when the rotary table 2 rotates.

[0055] By opening pin holes 27 on the outer periphery of the rotary table 2, the positioning pin 3 can generate a large locking force due to the rotational pressure of the lever plate 34. Thus, the positioning pin 3 can stably insert and lock the rotary table 2, ensuring the stability of the hollow drill 22 when rotating and drilling, thereby improving the reliability and processing quality of the drilling operation.

[0056] Furthermore, the outer periphery of the positioning pin 3 is provided with a protruding ring 31 located inside the pin sleeve 32. The pin sleeve 32 is provided with a spring 33 that abuts against the protruding ring 31 and drives the positioning pin 3 to move and abut against the lever plate 34. Thus, the positioning pin 3 is abutted by the spring 33 located inside the pin sleeve 32, so that the positioning pin 3 is kept away from the pin hole 27. At this time, the rotary table 2 can rotate flexibly and smoothly to switch the required hollow drill 22. When the rotary table 2 rotates or is about to rotate to the required hollow drill 22, the lever plate 34 rotates and presses against the positioning pin 3, so that one end of the positioning pin 3 passes through the pin sleeve 32 and abuts against the outer periphery of the rotary table 2, and is inserted into the pin hole 27 as the rotary table 2 rotates, so as to achieve stable insertion and locking of the rotary table 2.

[0057] Furthermore, the insertion and engagement of the positioning pin 3 with the pin hole 27 greatly improves the machining positioning accuracy of the hollow drill 22, ensuring its quality during drilling.

[0058] This embodiment also discloses a processing method for a drilling device for a cutting bed, including:

[0059] S1. Drive the rotary table 2 to rotate to select the hollow drill 22 of the required specifications for drilling;

[0060] S2. When the rotary table 2 rotates, the positioning pin 3 is pressed by the lever plate 34 until it is inserted into the pin hole 27, so as to position the rotation of the rotary table 2.

[0061] S3. Drive the hollow drill 22 to rotate and move downward to punch holes in the fabric;

[0062] S4. Repeat S1 to S3 above until the fabric punching operation is completed, thereby fulfilling the multi-type punching processing requirements of the fabric.

[0063] When the hollow drill 22 finishes drilling, the top plate 141 moves away from the lever plate 34, and the positioning pin 3 is moved away from the pin hole 27 by the elastic force, so that the rotary table 2 can rotate again and select the hollow drill 22 of the required specifications for drilling, making the switching selection of the hollow drill 22 smoother.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
