Description

Technical Field

[0001] This invention relates to the field of spinning machine spindle technology, and in particular to a spindle holder assembly device for spinning machine spindles and its manufacturing method. Background Technology

[0002] The ring spinning frame is the main machine used in spinning, with the ring spinning frame being the most common. Its working principle involves taking the sliver or roving from the previous spinning process, which has been drafted, and twisting it through the rotating rings of the spinning machine. The winding speed of the bobbin is faster than that of the rings, and the drafted fibers are twisted into fine yarn. Typically, a ring spinning frame consists of a frame, drafting, winding, and lifting components, among which the spindle is the core part of the winding mechanism, as shown in the attached diagram. Figure 8 To be continued Figure 11 As shown, the spindle includes a spindle base 8, a spindle core connector 5, and a rod disc connector 4.

[0003] When supplying complete sets of ring spinning machine spindles, the spindle plate assembly 4 is inserted into the spindle seat assembly which is filled with lubricating oil, or the spindle seat assembly is packaged separately. The spindle seat assembly is formed by the spindle seat 8 and the spindle core assembly 5 connected by an interference fit through a small taper surface. The spindle seat nut 82 is usually screwed onto the external thread of the spindle seat 8 to ensure that the thread direction is consistent, the pitch is equal, and the diameter is properly matched to meet normal use. At the same time, it can avoid the situation where the number of spindle seats 8 and spindle seat nuts 82 is mismatched, which is equivalent to a physical inspection of the product quality.

[0004] When installing the spindle on the machine, the spindle seat nut 82 of the spindle seat connector needs to be unscrewed from the external thread of the spindle seat first. After passing the spindle seat connector through the spindle seat mounting hole on the rib in the frame component, the spindle seat nut 82 is reinstalled. The flat surface 81 of the spindle seat flange is oriented with an orienting tool, and the spindle seat connector is fixed on the rib with the corresponding spindle seat nut wrench. Then, lubricating oil is injected into the bearing 51 hole on the needle roller of the spindle core connector 5, and the rod plate connector 4 is inserted. From the perspective of lean production, removing the spindle seat nut 82 and reinstalling the spindle seat nut 82 results in non-value-adding installation waste.

[0005] In addition, the spindle needs to work continuously for a long time, so it is essential to maintain a clean and appropriate lubricant level to prevent accidental abrasive wear and sliding of the lower bearing 53 during high-speed rotation, and dry friction burning of the needle roller bearing 51. As the operating time increases, the lubricant will gradually decrease, requiring regular cleaning and oil replenishment of the spindle. The spindle core assembly 5 should be cleaned according to the required time and frequency, the old oil should be removed, and new lubricant should be added to maintain good bearing lubrication. When adding or changing the lubricant, the rod and disc assembly 4 needs to be manually pulled out from the spindle seat assembly one by one. Then, with the help of equipment such as a spindle oiling machine or tools such as an oil can or dropper, the old oil is extracted and new oil is added one by one from the bearing hole on the needle roller. When pulling out the rod and disc assembly 4, it is easy for fly shavings, spun threads, dust, and other contaminants to stick and be absorbed, which can easily cause bumps and deformation. There are also problems such as inaccurate oil addition, inconsistent lubricant level, and waste of manpower and time.

[0006] Spindles are characterized by large-scale production, with large specialized manufacturing enterprises often producing millions of spindles annually to meet market demand. In existing technology, the spindle holder (8) is an independent structural unit. During machining, high-performance, automated CNC equipment is commonly used, allowing for the completion of one piece in a single feeding and clamping operation. However, auxiliary time such as loading and unloading individual parts, clamping parts, and tool changes needs to be repeatedly cyclical, making it difficult to fully utilize the continuous processing capabilities of the equipment. Production efficiency remains low, especially for small, complex, and high-precision parts, where this auxiliary time consumption accounts for a significant proportion. Designing and using special tooling to clamp multiple small parts at once would also involve considerable complexity in terms of the structure and precision of positioning and clamping mechanisms. Even if this reduces the number of tool changes, the limitations remain difficult to fully address.

[0007] Therefore, in view of the problems existing in the spindle holder of the ring spinning machine in terms of installation, oil change maintenance and processing and manufacturing, those skilled in the art urgently need a new spindle holder assembly device for the spinning machine and its manufacturing method. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a spindle seat assembly device for a spinning machine and its manufacturing method, which can improve production and installation efficiency, ensure the verticality of the spindle assembly, and facilitate cleaning, filtering and replacement of lubricating oil, and has the beneficial effects of sufficient lubrication, low contamination rate and effective relief of high-speed bearing overheating.

[0009] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0010] A spindle seat assembly for a spinning frame includes a spindle seat assembly body, a sleeve, and a flange end cap; the spindle seat assembly body is elongated and has an oil storage cavity formed along its length; the upper end face of the spindle seat assembly body has multiple spindle seat holes communicating with the oil storage cavity; the sleeve is inserted into the spindle seat holes with an interference fit; the inner wall surface of the sleeve is adapted to the outer conical surface of the spindle core connector with an interference fit;

[0011] The oil storage chamber is open at both ends along its length, and the flange end cap is sealed to the open end of the oil storage chamber; oil pipe joint holes are opened on both sides of the lower end face of the spindle seat assembly body near the open end, and the oil pipe joint holes are connected to the oil storage chamber; the side of the spindle seat assembly body is detachably connected to the frame rib.

[0012] The beneficial effects of this invention are as follows: Multiple spindle seat holes are opened on the spindle seat assembly body, allowing for the simultaneous installation of multiple spindle core couplings, functionally equivalent to multiple individual spindle seats in the prior art. The assembly method for each spindle core coupling is the same as in the prior art, i.e., the spindle core couplings are connected via a tapered interference fit. Therefore, the production and assembly of the prior art spindle core couplings and rod disc couplings are not affected. The spindle seat assembly device of this invention can complete the machining of multiple spindle seat holes at once, reducing tool change time and frequency, increasing actual cutting time, and maximizing the positioning accuracy and machining accuracy of the parts, as well as production efficiency. Through the connection between the spindle seat assembly body and the frame ribs, it is no longer necessary to orient the original spindle seat flange flat surface one by one, nor is it necessary to tighten the spindle seat nuts, while also eliminating the need for the outer spindle seat tube. Threading and spindle seat nuts improve installation efficiency; multiple spindle seat assembly oil storage chambers can be connected in series and linked to the oil tank through the oil pipe connector hole, allowing cleaning, filtering, and oil changing operations without inserting or removing the rod disc assembly, avoiding accidental deformation of the rod disc and saving oil changing time; clean lubricating oil can prevent impurities and abrasive particles from damaging the sliding bearing and reduce the heat generated by the bearing at high speed; even during spinning, slow circulation of lubricating oil can more effectively alleviate the heat generation of the high-speed rotating bearing and will not affect the continuous spinning process; furthermore, the lubricating oil level is consistent and the damping effect is consistent, ensuring sufficient lubrication of the upper and lower bearings of the spindle assembly, reducing the fouling rate, ensuring sufficient lubrication of the bearings on the needle rollers, and reducing the difference in the damping effect of the lubricating oil on the vibration of the rod disc assembly.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, a sealing gasket is installed between the side of the flange end cover and the opening end face of the oil storage cavity and is connected by bolts; a rectangular groove is recessed inward on the opening end face of the oil storage cavity; a sealing step is protruded from the side of the flange end cover and adapted to the rectangular groove; the sealing step passes through the sealing gasket and is inserted into the rectangular groove; a sealing ring is installed between the outer wall of the sealing step and the inner wall of the rectangular groove.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the sealing step and the rectangular groove are sealed and connected by a sealing ring; and the side of the flange end cover is sealed and connected to the opening end face of the oil reservoir by a sealing gasket; thus, the sealing is achieved through the joint action of the sealing ring and the sealing gasket, resulting in a good sealing effect and effectively preventing lubricating oil leakage.

[0016] Furthermore, one side of the spindle seat assembly body is formed with a T-shaped groove extending along its length; the other side of the spindle seat assembly body is formed with a U-shaped groove extending along its length; the T-shaped groove is connected to the frame rib by T-bolts.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the spindle seat assembly body is fixed to the frame rib by tightening with T-bolts, and the connection is firm; the U-shaped groove can improve the strength and deformation resistance of the spindle seat assembly body.

[0018] Furthermore, the outer side of the T-slot extends outward to form a right-angle positioning step; the right-angled surface of the right-angle positioning step fits and is positioned in contact with the right-angled surface of the frame rib.

[0019] The beneficial effects of adopting the above-mentioned further solution are: the mutually perpendicular horizontal and vertical surfaces of the right-angle positioning step are in contact with the horizontal and vertical surfaces of the frame ribs, which can improve the installation positioning accuracy and installation efficiency.

[0020] Furthermore, the ingot base assembly body is integrally formed from aluminum profiles and has a hollow internal structure; the hollow structure is the oil storage cavity.

[0021] The advantages of adopting the above-mentioned further solutions are: it can improve the material utilization rate, while the hollow structure also serves as a lubricating oil storage container; and the aluminum profile has high thermal conductivity, which can reduce the heat generated by the high-speed operation of the bearing.

[0022] Furthermore, the oil pipe connector hole is a threaded hole and is connected to the oil tank through an oil pipe.

[0023] The advantages of adopting the above-mentioned further solutions are: the oil pipe joint hole is connected to the oil tank through the oil pipe for lubrication; or multiple spindle seat assembly devices are connected in series through oil pipes to the oil tank to achieve common lubrication of multiple spindle seat assembly devices, which is efficient and easy to install.

[0024] Furthermore, the diameter D of the spindle seat hole is greater than the width W of the oil storage cavity; a gap L is provided between the bottom surface of the sleeve and the inner bottom surface of the oil storage cavity.

[0025] The beneficial effects of adopting the above-mentioned further solution are: the diameter of the spindle seat hole is larger than the width between the inner wall surfaces of the oil storage cavity, which facilitates the fixing of the sleeve inside the spindle seat assembly body; the gap between the bottom surface of the sleeve and the bottom surface of the oil storage cavity allows the bottom ends of each sleeve to be connected, which facilitates the simultaneous lubrication of the spindle core assembly in each sleeve through the oil storage cavity.

[0026] Furthermore, a support strip is formed protruding upward from the center of the bottom surface of the oil storage cavity; the top surface of the support strip abuts against the bottom surface of the sleeve.

[0027] The beneficial effect of adopting the above-mentioned further solution is that the support bar provides support for the casing and the spindle coupling inside, and the gap on both sides of the support bar is connected to the bottom end of the casing, thereby enabling the common lubrication of the spindle couplings in multiple casings.

[0028] Furthermore, 6-10 holes are evenly distributed along the length of the ingot seat assembly body.

[0029] The beneficial effect of adopting the above-mentioned further solution is that, in order to ensure the vertical accuracy requirements of the center of each spindle assembly, the number of spindle seat holes on the spindle seat assembly body should not be too many, and 6-10 spindle seat holes are more appropriate.

[0030] The present invention also provides a method for manufacturing a spindle holder assembly for a spinning frame, comprising the following steps:

[0031] S1: The elongated spindle seat assembly body has a hollow oil storage cavity inside; the spindle seat assembly body is placed on the processing equipment for positioning and clamping; multiple spindle seat holes are machined on the upper end face of the spindle seat assembly body according to the designed spindle spacing; oil pipe joint holes are machined on both sides of the lower end face of the spindle seat assembly body near the opening of the oil storage cavity.

[0032] S2: Machining the outer circumference of the sleeve; the outer circumference of the sleeve is interference-fitted with the spindle seat hole; and pressing the machined sleeve into the spindle seat hole;

[0033] S3: Position and clamp the casing again on the machining equipment; finish machine the conical surface of the inner hole of the casing, which is adapted to and interference fits the outer conical surface of the spindle coupling;

[0034] S4: Machining the flange end cap; sealing the flange end cap and installing it at the opening end of the oil storage cavity;

[0035] S5: After cleaning all parts, press the spindle coupling into the sleeve, inject a small amount of rust-preventive oil or lubricating oil into the spindle coupling, and cover it with a dust cap; form the finished product.

[0036] The beneficial effects of the manufacturing method of the spindle seat assembly device for a spinning frame of the present invention are as follows: Each spindle seat hole is press-fitted with a sleeve to form a tight connection structure, and then the inner conical surface of the inner hole is precision machined to match the spindle core assembly. Thus, by simultaneously machining the inner hole of the sleeve, both machining efficiency and the perpendicularity of the center of each sleeve's inner hole are improved, thereby ensuring the perpendicularity of each spindle core assembly after installation. By machining the outer diameter of the sleeve first and then machining the inner hole after installation, the influence of the installation fit accuracy on the perpendicularity of the inner hole of the sleeve can be avoided. The tooling positioning and clamping methods used are simple; the machining of several spindle seat holes of one or more spindle seat assemblies can be completed in one tool change, reducing tool change time and frequency, increasing actual cutting time, and streamlining the process. This maximizes the positioning accuracy and machining accuracy of the parts, as well as production efficiency.

[0037] As can be seen from the above technical solution, compared with the prior art, the present invention provides a spindle seat assembly device for a spinning frame and its manufacturing method, which has the following beneficial effects:

[0038] (1) The spindle seat assembly device of the present invention can complete the processing of multiple spindle seat holes at one time, reducing tool change time and frequency, increasing actual cutting processing time, maximizing the positioning accuracy and processing accuracy of parts, as well as production efficiency; by connecting the spindle seat assembly body with the frame rib, it is no longer necessary to orient the original spindle seat flange flat surface one by one, nor is it necessary to tighten the spindle seat nut, avoiding the time-consuming and laborious installation of a single spindle seat with the frame rib; at the same time, it eliminates the need for external thread processing of the spindle seat tube and spindle seat nut, simplifying the installation operation steps and improving installation efficiency;

[0039] (2) This invention connects the spindle chambers in each sleeve through the oil storage chamber, and connects the oil storage chambers of multiple spindle seat assemblies in series through oil pipes and connects them to the oil tank. First, it can realize cleaning, filtering and oil changing operations without inserting or removing the rod and disc assembly, avoiding accidental deformation of the rod and disc and saving oil changing operation time. Second, clean lubricating oil can avoid damage to the sliding bearing by impurities and abrasive particles, and reduce the heat generated by the high-speed operation of the bearing. Even during the spinning process, the slow circulation of lubricating oil can more effectively alleviate the heating of the high-speed operating bearing and will not affect the continuous spinning. Third, the lubricating oil level is consistent and the damping effect is consistent, ensuring that the bearing on the needle roller is fully lubricated, reducing the difference in the damping effect of the lubricating oil on the vibration of the rod and disc assembly, and ensuring the consistency of the operation of each rod and disc assembly.

[0040] (3) In the manufacturing method of the spindle seat assembly of the present invention, by first processing the outer periphery of the sleeve, pressing it into the spindle seat hole, and then processing the conical surface of the inner hole of the sleeve, the influence of the installation fit accuracy on the verticality of the center of the inner hole of the sleeve can be avoided, ensuring the verticality and consistency of the spindle assembly installed in each sleeve; and by processing the inner hole of the sleeve at the same time, the processing efficiency is improved.
