Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, specifically to an embroidery machine base. Background Technology

[0002] In embroidery machines, the machine base is a key component, and its structural design and performance directly affect the machine's operational stability and service life. Currently, solid lubrication is commonly used for the main body of the embroidery machine base. In this method, the connection between the bevel gears of the H-axis and the gear shaft is often open. However, when the embroidery machine is running at high speed, the lubricating grease used in solid lubrication is easily thrown out due to centrifugal force and other factors (i.e., the "double-flying" phenomenon), resulting in a significant decrease in lubrication effectiveness. This not only increases the wear of mechanical parts but may also cause equipment failure, affecting the normal working efficiency and embroidery quality of the embroidery machine.

[0003] To address the issue of poor lubrication performance of solid lubricants at high speeds, existing technologies typically employ oil boxes to improve lubrication (e.g., the H-shaft gear oil box for towel embroidery disclosed in application CN202222567763.7). However, adding an oil box not only increases the overall structural complexity of the machine base but also raises manufacturing costs and occupies space, hindering the compact design and maintenance of the embroidery machine. Therefore, a new technical solution is urgently needed that simplifies the structure and reduces costs while ensuring good lubrication performance. Utility Model Content

[0004] In view of the shortcomings in the background technology, this utility model provides an embroidery machine base.

[0005] The technical solution adopted by this utility model is: an embroidery machine base, including a base body, an oil storage cavity for storing lubricating fluid integrally formed on the base body, a first shaft hole for installing an H-axis is provided at both ends of the oil storage cavity, and a second shaft hole for connecting a gear shaft is provided on the other side, and the H-axis is rotary sealed with the first shaft hole and the gear shaft is rotary sealed with the second shaft hole.

[0006] Furthermore, an inspection port is provided on the oil storage chamber, and an inspection plate is fixed to the inspection port by screws.

[0007] Furthermore, the outer wall of the oil storage cavity is provided with a concave surface for accommodating the inspection plate, the depth of the concave surface is greater than or equal to the thickness of the inspection plate, and a sealing gasket is placed between the inspection plate and the concave surface.

[0008] Furthermore, it also includes an oil injection hole for injecting oil into the oil storage chamber, and a sealing bolt is screwed onto the oil injection hole.

[0009] Furthermore, the oil injection hole is located on the inspection plate.

[0010] Furthermore, the H-axis and the gear shaft are respectively provided with a first bevel gear and a second bevel gear, which mesh with each other.

[0011] Furthermore, the gear shaft is rotary sealed to the second shaft hole via a first bearing, a bushing, and a snap ring.

[0012] Furthermore, the H-axis is rotary sealed to the first shaft hole via an oil seal and a second bearing.

[0013] The beneficial effects of this utility model are:

[0014] 1. Excellent lubrication effect: This application directly sets an oil reservoir for storing lubricating fluid on the machine base. Compared with solid lubricating grease, liquid lubricating fluid can better adhere to the bevel gear connection between the H-axis and the gear shaft under high-speed rotation conditions, avoiding the loss of lubricating medium due to centrifugal force, effectively reducing friction and wear between mechanical parts, greatly improving the lubrication effect, and ensuring the long-term stable and efficient operation of the embroidery machine.

[0015] 2. Low cost: This patent abandons the traditional oil box design, reduces the manufacturing and installation costs of the oil box, simplifies the production process, reduces raw material and assembly costs, and improves the economic benefits and market competitiveness of enterprises and products.

[0016] 3. Simple structure: The oil storage chamber and the main body of the machine base are integrally formed, making the structure of the machine base more compact and reasonable, reducing the extra space occupied by adding an oil box, facilitating the overall layout design of the embroidery machine, and also reducing the difficulty and workload of later maintenance of the equipment, improving the convenience and efficiency of equipment maintenance.

[0017] In summary, this patent has achieved significant improvements in lubrication performance, cost control, and structural optimization, and has good application value and promotion prospects.

[0018] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0026] This utility model provides a base for an embroidery machine.

[0027] In this embodiment, refer to Figure 1-4 The embroidery machine base includes a base body 1, on which an oil storage cavity 2 for storing lubricating fluid is integrally formed. The oil storage cavity 2 has a first shaft hole 4 for installing an H-shaft 3 at both ends, and a second shaft hole 6 for connecting a gear shaft 5 on the other side. The H-shaft is rotary sealed with the first shaft hole and the gear shaft is rotary sealed with the second shaft hole.

[0028] In the above technical solution, an oil reservoir is integrally formed on the base body, integrating the function of storing lubricating fluid into the base body structure. This allows the transmission parts of the H-axis and gear shaft to be directly immersed in or near the liquid lubricating fluid. The first and second shaft holes are used to install the H-axis and gear shaft, respectively, and a rotary seal fit is used between the shaft and the shaft hole. This ensures normal shaft rotation and prevents lubricating fluid leakage from the oil reservoir, thus forming a relatively closed lubrication environment inside the base body. Compared to traditional solid lubrication and oil box designs, directly setting an oil reservoir in the base body to store liquid lubricating fluid allows for better fluidity and adhesion. Under high-speed rotation, it can continuously and evenly lubricate the transmission parts of the H-axis and gear shaft, effectively avoiding the "double-flying" phenomenon of lubricating grease and significantly improving the lubrication effect. At the same time, eliminating the need for a separate oil box simplifies the base structure and reduces manufacturing costs and installation space requirements.

[0029] Specifically, the oil storage chamber is provided with an inspection port 7, and an inspection plate 9 is fixed to the inspection port 7 by screws 8.

[0030] In this embodiment, an inspection port is provided on the oil storage chamber, and an inspection plate is installed with screws to form an openable and closable inspection channel. When it is necessary to inspect, clean, or repair the inside of the oil storage chamber, the screws can be unscrewed and the inspection plate removed, thereby facilitating access to the internal structure of the oil storage chamber by the operator.

[0031] Specifically, the outer wall of the oil storage cavity is provided with a concave surface 10 for accommodating the inspection plate. The depth of the concave surface 10 is greater than or equal to the thickness of the inspection plate, and a sealing gasket 11 is placed between the inspection plate and the concave surface.

[0032] In this embodiment, a concave surface is provided on the outer wall of the oil storage cavity to accommodate the maintenance plate. The depth of the concave surface is adapted to the thickness of the maintenance plate, ensuring that the maintenance plate is flush with or slightly lower than the surface of the machine base after installation, thus avoiding the impact of the maintenance plate protruding on the overall structure and installation of the machine base. A sealing gasket is placed between the maintenance plate and the concave surface. The elastic deformation of the sealing gasket fills the gap, further enhancing the sealing performance at the maintenance port and preventing lubricant leakage from the maintenance port.

[0033] Specifically, it also includes an oil injection hole 12 for injecting oil into the oil storage chamber, and a sealing bolt 13 is screwed onto the oil injection hole 12.

[0034] In this embodiment, an oil injection hole is provided to replenish the lubricating fluid in the oil storage chamber. The oil injection hole is sealed with a screw-on sealing bolt. When oil injection is needed, the sealing bolt is unscrewed and the lubricating fluid is injected through the oil injection hole. After the oil injection is completed, the sealing bolt is tightened to seal the oil injection hole and prevent lubricating fluid leakage and external impurities from entering the oil storage chamber.

[0035] Specifically, the oil injection hole is located on the inspection plate.

[0036] In this embodiment, the oil injection hole is located on the inspection plate, which facilitates independent machining of the oil injection hole.

[0037] Specifically, the H-axis and the gear shaft are respectively provided with a first bevel tooth 14 and a second bevel tooth 15, and the first bevel tooth and the second bevel tooth mesh with each other.

[0038] In this embodiment, a first bevel gear and a second bevel gear that mesh with each other are respectively provided on the H-axis and the gear shaft. Through the meshing transmission of the bevel gears, the conversion and transmission of power are realized. The special tooth profile design of the bevel gears can realize the transmission between two intersecting shafts in a small space, which is suitable for the internal structural layout of the machine base.

[0039] Specifically, the gear shaft is rotary sealed to the second shaft hole via a first bearing 16, a bushing 17, and a snap ring 18; the H-shaft is rotary sealed to the first shaft hole via an oil seal 19 and a second bearing 20.

[0040] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
