Description

Technical Field

[0001] This utility model relates to the field of printhead accessories, and in particular to a high-precision industrial printer printhead accessory processing device. Background Technology

[0002] High-precision industrial printer printhead accessories are the core system ensuring printing accuracy and efficiency, composed of a variety of precision components working together. The matching pressure chamber and piezoelectric and thermal bubble drive elements work in tandem, generating pressure waves through voltage control to propel the ink. An internal filter in the ink channel prevents clogging, and the circuit board converts signals into electrical pulses to control the drive elements. The board encapsulation provides thermal management and protection. Some high-end models are also equipped with auxiliary accessories such as positioning holes and pressure sensors, balancing ease of maintenance and fault monitoring to meet the high-speed, high-durability requirements of industrial applications.

[0003] High-precision industrial printer printhead component processing focuses on micron-level precision control, integrating multidisciplinary process technologies. Holes are machined on stainless steel or sapphire substrates using deep reactive ion etching, complemented by laser calibration to ensure hole position tolerances. The drive component substrate relies on precision photolithography and electroplating processes to fabricate micron-level circuits on ceramic or silicon-based materials, enabling precise signal transmission. Ink channels and pressure chambers are shaped using five-axis CNC milling or electrochemical etching. After machining, dimensions are checked with a laser interferometer, and sealing is tested with high-pressure gas. Some components also require vacuum coating to enhance corrosion resistance. The entire process must be carried out in a Class 1000 cleanroom to prevent micro-dust from affecting precision.

[0004] Existing high-precision industrial printer printhead parts processing methods vary greatly in terms of part types. Nozzle plates are ultra-thin sheet substrates that require vacuum suction fixtures to prevent deformation during clamping. Different shaped parts require dedicated clamping solutions, and the processing steps are diverse. Photolithography requires light-transmitting positioning fixtures to ensure circuit pattern alignment, while CNC milling requires high-rigidity fixtures to resist cutting forces. General-purpose fixtures cannot adapt to the needs of the entire process, making it difficult to guarantee the printhead's ejection accuracy and stability, thus affecting the final product quality of high-precision industrial printer printhead parts. Therefore, a high-precision industrial printer printhead parts processing device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-precision industrial printer printhead accessory processing device, which aims to improve the problem that the general fixtures of existing high-precision industrial printer printhead accessory processing devices cannot adapt to the needs of the entire process and cannot guarantee the printhead spraying accuracy and stability, thus affecting the final product quality of high-precision industrial printer printhead accessories.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision industrial printer nozzle accessory processing device, comprising a processing machine body, wherein a clamping structure is provided inside the processing machine body; the clamping structure includes a body, wherein a bidirectional screw is threadedly connected inside the body, a bevel gear is passed through and fixedly connected inside the bidirectional screw, a sliding block is slidably connected inside the body, a connecting block is fixedly connected to the side of the sliding block, a rotating block is rotatably connected inside the connecting block, a locking rod is fixedly connected inside the connecting block, a limit block is fixedly connected to the side of the locking rod, a rotating rod is rotatably connected inside the connecting block, a clamping block is fixedly connected to the outer side of the rotating rod, a main rotating rod is rotatably connected inside the body, a handle is fixedly connected to one side of the main rotating rod, a fixing nut is threadedly connected inside the handle, a bevel gear is fixedly connected to the other side of the main rotating rod, and a vibration damping structure is provided on the side of the body.

[0008] As a further description of the above technical solution: the sliding block has a threaded groove inside, and the threaded groove inside the sliding block matches the size of the bidirectional screw.

[0009] As a further description of the above technical solution: one side of the spring is fixedly connected to the side of the connecting plate, and the other side is fixedly connected to the inside of the base.

[0010] As a further description of the above technical solution: the first bevel gear and the second bevel gear are generally in a mutually perpendicular meshing state.

[0011] As a further description of the above technical solution: the inside of the rotating block is provided with a sliding groove, and the size of the sliding groove inside the rotating block matches that of the locking rod.

[0013] As a further description of the above technical solution: the connecting plate has a flange groove inside, and the size of the flange groove inside the connecting plate matches the size of the fixed flange.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when the operator uses the processing machine body to perform precision machining on the nozzle accessories, the throttle located on the side of the clamping mechanism needs to be rotated. The first bevel gear is driven by the second bevel gear and begins to rotate. When the bidirectional screw rotates, the clamping block will first contact the outer surface of the nozzle accessories. The rotating block itself is movably connected to the connecting block through the annular groove opened inside the connecting block. According to the overall shape curve of the nozzle accessories, it can also effectively avoid displacement, shaking and other problems in the subsequent precision machining process through the adaptive rotation of the clamping block and the angle adjustment of the rotating block, thus providing a reliable guarantee for machining accuracy.

[0016] 2. In this utility model, when the vibration of the machine body is transmitted to the support leg and then to the connecting plate, the impact force generated by the vibration will first act on the spring. The spring absorbs part of the vibration energy through its own elastic deformation. At the same time, fixed flanges are installed on both sides of the connecting plate. The fixed flanges are divided into upper and lower parts. The upper part is welded and fixed to the connecting plate, and the lower part is bolted to the base. A small buffer gap is reserved at the flange connection. Through the elastic buffering of the spring and the limiting function of the fixed flange, the vibration generated by the machine body is greatly diluted, which significantly reduces the noise during the processing and avoids the vibration from affecting the processing accuracy of the nozzle accessories.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a high-precision industrial printer nozzle accessory processing device, comprising a processing machine body 1. The processing machine body 1 internally houses two sets of sliding blocks 24, connecting blocks 25, rotating blocks 26, clamping rods 27, limiting blocks 28, rotating rods 29, and clamping blocks 210. The processing machine body 1 internally houses a clamping structure 2. The clamping structure 2 includes a body 21. A bidirectional screw 22 is threadedly connected internally to the body 21. A bevel gear 23 is passed through and fixedly connected internally to the bidirectional screw 22. A sliding block 24 is slidably connected internally to the body 21. The sliding block 24 has a threaded groove that matches the size of the bidirectional screw 22. This design allows the bidirectional screw 22 to rotate, driving the sliding block 24 to slide within the body 21. A connecting block 25 is fixedly connected to the side of the sliding block 24. A rotating block 26 is rotatably connected internally to the connecting block 25. A clamping rod 27 is fixedly connected internally to the connecting block 25. The rotating block 26 has a threaded groove inside. The sliding groove inside the rotating block 26 matches the size of the clamping rod 27. This design allows the rotating block 26 to rotate inside the connecting block 25 via the clamping rod 27. A limit block 28 is fixedly connected to the side of the clamping rod 27. A rotating rod 29 is rotatably connected inside the connecting block 25. A clamping block 210 is fixedly connected to the outside of the rotating rod 29. The rotating block 26 has a rotating groove inside, and the size of the rotating groove inside the rotating block 26 matches the size of the clamping block 210. This design allows the clamping block 210 to rotate inside the rotating block 26. The main rotating rod 211 is rotatably connected inside the body 21. A handle 212 is fixedly connected to one side of the main rotating rod 211. A fixing nut 213 is threaded inside the handle 212. A bevel gear 214 is fixedly connected to the other side of the main rotating rod 211. The bevel gear 23 and the bevel gear 214 are in a mutually perpendicular meshing state. This design allows the main rotating rod 211 to rotate and drive the bidirectional screw 22 to start rotating through the bevel gear 214. A vibration damping structure 3 is provided on the side of the body 21.

[0025] Reference Figure 3 - Figure 4The vibration damping structure 3 includes a support leg 31. A connecting plate 32 is fixedly connected to the side of the support leg 31. A base 34 is elastically connected to the side of the connecting plate 32 away from the support leg 31 via a spring 33. One side of the spring 33 is fixedly connected to the side of the connecting plate 32, and the other side is fixedly connected to the inside of the base 34. This design allows the connecting plate 32 to be connected to the base 34 via the spring 33. A fixing flange 35 is connected to the internal flange of the base 34. A flange groove is opened inside the connecting plate 32, and the size of the flange groove inside the connecting plate 32 matches the size of the fixing flange 35. This design allows the connecting plate 32 to be fixed to the base 34 via the fixing flange 35.

[0026] Working Principle: When the operator uses the machining body 1 to precision machine the nozzle parts, the first step is to accurately and stably place the nozzle parts to be processed into the pre-set machining slot of the machining body 1, ensuring that the parts are initially in the machining center area. Then, the handle 212 located on the side of the clamping mechanism is rotated. At this time, the handle 212 will start to rotate around its own axis, and through its fixed connection structure with the main rotating rod 211, it directly drives the main rotating rod 211, which is coaxially fixed on the side, to rotate synchronously. The other end of the main rotating rod 211 is firmly fixed to the second bevel gear 214 by a key connection or welding. As the main rotating rod 211 rotates, the second bevel gear 214 also rotates. This second bevel gear 214 is fully meshed with the first bevel gear 23 set vertically on the front. Under the meshing action of the gear transmission, the first bevel gear 23 is driven by the second bevel gear 214 and begins to rotate. Because the inner hole of the first bevel gear 23 is fixed to the side of the double-acting screw 22 and completely penetrates the center of the first bevel gear 23, The rotation of the bevel gear 23 directly drives the bidirectional screw 22 to rotate around its own axis. The outer side of the bidirectional screw 22 is machined with symmetrical, opposing threaded grooves. Sliding blocks 24, matching the threaded grooves, are fitted at both ends of the screw. The outer side of the sliding blocks 24 is tightly fitted with the guide groove inside the machine body 21. When the bidirectional screw 22 rotates, the threaded grooves generate an axial thrust on the sliding blocks 24, causing the sliding blocks 24 on both sides to slide steadily towards the center of the bidirectional screw 22 along the guide structure inside the machine body 21. Connecting blocks 25 are fixed to the sides of the sliding blocks 24 by bolts or welding. As the sliding blocks 24 move, the connecting blocks 25 on both sides also move synchronously towards the center. The end of the connecting block 25 furthest from the sliding block 24 is connected to a clamping block 210 via a rotating structure. As the connecting block 25 approaches the nozzle accessory, the clamping block 210 will first contact the outer surface of the nozzle accessory. As the connecting block 25 continues to move, the clamping block 210 will be subjected to the squeezing force of the accessory surface and will adaptively rotate around the rotating rod 29 in the preset shaft hole inside the rotating block 26 until the clamping surface of the clamping block 210 completely conforms to the local outline of the nozzle accessory. At the same time, the rotating block 26 itself is movably connected to the connecting block 25 through an annular rotating groove opened inside the connecting block 25. It will flexibly rotate within the rotating groove according to the overall outline curve of the nozzle accessory, further adjusting the clamping angle and position of the clamping block 210, ultimately achieving full contact and compression between the clamping surface of the clamping block 210 and the outer surface of the nozzle accessory. The clamping mechanism on the other side of the machining body 1 adopts the same transmission and adaptation principle. The clamping blocks 210 on both sides apply a stable and uniform clamping force to the nozzle accessories simultaneously. Even when faced with nozzle accessories with irregular shapes, different models, or different sizes, the nozzle accessories can be firmly fixed in the machining groove by the adaptive rotation of the clamping blocks 210 and the angle adjustment of the rotating block 26. This effectively avoids displacement and shaking during subsequent precision machining, providing a reliable guarantee for machining accuracy.

[0027] When the machine body 1 performs precision machining on the nozzle components, the operation of its internal motor and the cutting of the cutting tools will cause the machine body 21 to vibrate violently. If these vibrations are directly transmitted to the outside, they will cause structural resonance and generate significant noise. To address this issue, the machine effectively buffers the vibration through a vibration-damping structure 3 at the bottom: the support leg 31 under the machine body 21 is made of metal, and its side is fixed with a horizontally extending connecting plate 32 by welding or bolts. The connection between the connecting plate 32 and the base 34 below is not rigidly connected, but rather multiple sets of springs 33 are evenly distributed. The upper and lower ends of the springs 33 are firmly fixed to the connecting plate 32 and the base 34 by clips or welding, respectively. When the vibration of the machine body 21 is transmitted to the support leg 31 and then to the connecting plate 32, the impact force generated by the vibration will first act on the springs 33. Spring 33 absorbs some vibration energy through its elastic deformation. When subjected to downward pressure, spring 33 compresses and deforms, converting kinetic energy into elastic potential energy. When the pressure weakens, spring 33 rebounds and releases the potential energy. During this process, the intensity of vibration is significantly diluted, preventing direct transmission to base 34 and avoiding overall resonance. Simultaneously, fixing flanges 35 are installed on both sides of connecting plate 32. The fixing flanges 35 are divided into upper and lower parts; the upper part is welded to connecting plate 32, and the lower part is bolted to base 34, with a small buffer gap reserved at the flange connection. This structure avoids direct vibration transmission caused by rigid connections and, in conjunction with spring 33, further limits the lateral sway of connecting plate 32, effectively controlling vibration in both vertical and horizontal directions. Through the elastic buffering of spring 33 and the limiting effect of fixing flange 35, the vibration generated by machine body 21 is significantly diluted, ultimately reducing noise during processing and preventing vibration from affecting the processing accuracy of nozzle accessories.
