Description

Technical Field

[0001] This utility model relates to the field of textile equipment parts processing technology, specifically to a mercerizing machine straight roller clamping mechanism and a turning and grinding machine. Background Technology

[0002] Mercerizers, as equipment in the textile industry, are mainly used to treat cotton yarns and fabrics with concentrated caustic soda solution, and then remove the alkali from the fabric through a subsequent washing process, thereby improving the luster, absorbency, and dimensional stability of cotton fibers. Based on the structural differences in the spreading device, mercerizers can generally be divided into four types: fabric clamp type, straight roller type, curved roller type, and composite spreading type. Among them, the straight roller type mercerizer is widely used in the processing of mid-to-high-end cotton fabrics due to its stable processing and minimal damage to the fabric.

[0003] As a core component of straight roller mercerizing machines, the surface precision of the straight roller directly affects the mercerizing effect and processing quality of the fabric. Turning and grinding are crucial processes in the manufacturing of straight rollers to ensure their surface precision. However, because the bore diameter of straight rollers in mercerizing machines is typically large, far exceeding the clamping range of conventional machine tool chucks, they cannot be directly clamped and positioned using traditional three-jaw or four-jaw chucks. Specialized tooling fixtures are required to complete the turning and grinding processes.

[0004] Existing tooling fixtures used for straight roller processing in mercerizing machines generally suffer from complex structures. They typically require the design of multiple positioning components, clamping components, and auxiliary support structures, which not only makes processing and manufacturing difficult but also results in high production costs.

[0005] Therefore, existing technologies need to be improved. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the tooling fixtures for straight roller processing are complex in structure and high in cost. The purpose is to provide a straight roller fixture mechanism for mercerizing machines and a turning and grinding machine tool. By adopting the corresponding technical means, it has the advantage of reducing costs, while ensuring the positioning accuracy and stability of the straight roller during turning and grinding.

[0007] This utility model is achieved through the following technical solution:

[0008] In a first aspect, this utility model provides a straight roller clamping mechanism for a mercerizing machine, which includes a straight roller body, a flange one at one end of the straight roller body, a flange two at the other end of the straight roller body, a fixed shaft that is clamped by a machine tool jaw connected to the outer center of the flange one, and a positioning hole that is inserted into the outer center of the flange two.

[0009] Furthermore, in this invention, the aforementioned positioning hole is configured as a tapered hole.

[0010] Furthermore, in this utility model, the outer diameter of the flange is the same as the inner diameter of the straight roller body, and the flange is welded to the straight roller body.

[0011] Furthermore, in this utility model, the outer end face of the flange is flush with the end face of the straight roller body.

[0012] Furthermore, in this utility model, the outer diameter of the second flange is the same as the inner diameter of the straight roller body, and the second flange is welded to the straight roller body.

[0013] Furthermore, in this utility model, the outer end face of the flange two is flush with the end face of the straight roller body.

[0014] Furthermore, in this utility model, a steel plate is provided on the outer side of the flange two described above, and the steel plate abuts against the end of the straight roller body.

[0015] Furthermore, in this invention, the centers of the positioning hole, the straight roller body, and the fixed shaft are located on the same straight line.

[0016] Furthermore, in this utility model, the first flange and the second flange are configured as used flanges.

[0017] Secondly, this utility model also provides a turning and grinding machine tool, which is equipped with the mercerizing machine straight roller clamping mechanism, including machine tool jaws and machine tool cone top, wherein the machine tool jaws clamp the fixed shaft and the machine tool cone top is inserted into the positioning hole.

[0018] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0019] 1. Simple structure: This utility model sets flanges at both ends of the straight roller body, with a fixed shaft on flange one and positioning holes on flange two. It directly utilizes the machine tool's own jaws and cone apex for clamping and positioning, eliminating the need for complex tooling fixtures. Furthermore, the flanges can be repaired and reused from scrap flanges, further reducing material costs. Compared to existing tooling fixtures, the cost is significantly lower.

[0020] 2. Stable processing quality: In this utility model, the center of the positioning hole, the straight roller body, and the fixed shaft are coaxial, ensuring that the straight roller body has a small eccentricity during rotation; the fit between the tapered positioning hole and the machine tool cone tip can effectively avoid ripples or dimensional deviations on the surface of the straight roller.

[0028] Example 1

[0029] Combination Figures 1 to 3As shown, this embodiment 1 provides a straight roller clamping mechanism for a mercerizing machine, including a straight roller body 1. One end of the straight roller body 1 is provided with a flange 2, and the other end of the straight roller body 1 is provided with a flange 3. The outer center of the flange 2 is connected to a fixed shaft 4 that is clamped by the machine tool jaws, and the outer center of the flange 3 is provided with a positioning hole 5 that is inserted by the machine tool cone tip.

[0030] Combination Figure 2 As shown, the positioning hole 5 is configured as a tapered hole, and the taper of the tapered hole matches the taper of the machine tool cone tip. Morse taper or metric standard taper is usually used to achieve a tight fit and improve positioning accuracy.

[0031] Reference Figure 2 As shown, the outer diameter of flange 2 is the same as the inner diameter of the straight roller body 1. Flange 2 is welded to the straight roller body 1 using manual arc welding or CO2 gas shielded welding. Before welding, the mating surfaces of flange 2 and straight roller body 1 are ground to remove oxide scale and oil, ensuring weld strength. The outer end face of flange 2 is flush with the end face of straight roller body 1, ensuring uniform force distribution at the end of straight roller body 1 and preventing vibration caused by uneven end faces during processing.

[0032] Reference Figure 2 As shown, the outer diameter of flange 2 3 is the same as the inner diameter of the straight roller body 1. Flange 2 3 is welded to the straight roller body 1, and the welding process is the same as that of flange 1 2 to ensure the symmetry of the connection at both ends. The outer end face of flange 2 3 is flush with the end face of the straight roller body 1, forming a symmetrical design with the structure of flange 1 2.

[0033] Specifically, flange 2 and flange 3 are made from discarded flanges from textile mills, using Q235B material. Their outer diameter and the inner diameter of the straight roller body 1 are both 160mm, and the clearance between them is controlled within 0.5mm-1mm. Flange 2 has a 100mm diameter mounting hole pre-drilled at its center for connection to the fixed shaft 4. The fixed shaft 4 is used for clamping by machine tool jaws.

[0034] Flange 23 has the same specifications as flange 12 and is also a used flange. During installation, flange 23 is placed at the other end of the straight roller body 1, so that the outer end face is flush with the end face of the straight roller body 1. It is welded using the same welding process as flange 12 to ensure the symmetry of the structure at both ends.

[0035] Furthermore, combined Figure 3 As shown, a steel plate 6 can also be installed on the outer side of flange 2 3. The steel plate 6 abuts against the end of the straight roller body 1. The thickness of the steel plate 6 is 10mm, and it is made of Q235 ordinary carbon structural steel. Its function is to enhance the structural strength of flange 2 3 and prevent flange 2 3 from deforming when the machine tool cone top applies a tightening force.

[0036] It should be noted that the centers of the positioning hole 5, the straight roller body 1, and the fixed shaft 4 are located on the same straight line, that is, the coaxiality error of the three does not exceed 0.02mm, ensuring that the straight roller body 1 will not experience eccentric vibration during rotation and guaranteeing processing accuracy.

[0037] Furthermore, since flange 12 and flange 23 are made from scrap flanges, the scrap flanges can be standard flanges discarded by textile mills or machinery factories. After repair and polishing, they can be reused, which greatly reduces material costs.

[0038] Example 2

[0039] This utility model provides a turning and grinding machine tool, which is equipped with a mercerizing machine straight roller clamping mechanism according to any of the above, including machine tool jaws and machine tool cone top, the machine tool jaws clamping and fixing shaft 4, and the machine tool cone top inserting into positioning hole 5.

[0040] The principle of this utility model is as follows:

[0041] The straight roller clamping mechanism and turning and grinding machine tool of the mercerizing machine in this embodiment are mainly used for turning and grinding the outer circle of the straight roller cylinder 1. Its working principle is based on the clamping of the machine tool's jaws and the positioning of the cone top. The specific process is as follows:

[0042] Clamping and positioning process: The assembled mercerizing machine straight roller clamping mechanism is hoisted to the machining station of the lathe and grinder, aligning the clamping section of the fixed shaft 4 with the jaws of the machine tool chuck. The machine tool chuck is then operated to tighten the jaws, clamping the clamping section of the fixed shaft 4, thus fixing one end of the straight roller mechanism. Then, the machine tool tailstock is adjusted so that the machine tool cone apex is aligned with the positioning hole 5 on the flange 2 3. The tailstock is slowly moved to insert the machine tool cone apex into the positioning hole 5 until the cone apex is in contact with the hole wall of the positioning hole 5, thus positioning the other end of the straight roller mechanism. At this point, the straight roller mechanism achieves two-point positioning through the fixed shaft 4 and the positioning hole 5. The central axis of the positioning hole 5, the straight roller cylinder 1, and the fixed shaft 4 coincides with the rotation axis of the machine tool spindle.

[0043] Processing procedure: Start the machine tool spindle. The spindle drives the fixed shaft 4 to rotate through the chuck. The fixed shaft 4 drives the straight roller body 1 to rotate synchronously through the flange 2. Due to the fit between the positioning hole 5 and the machine tool cone top, the radial runout of the straight roller body 1 is limited, which greatly improves the rotational accuracy of the straight roller body 1.

[0044] Unloading process: After processing is completed, use a hoisting tool to connect the straight roller body 1, loosen the cone top of the machine tool tailstock so that the cone top exits from the positioning hole 5, then operate the machine tool chuck to loosen the jaws and release the clamping of the fixed shaft 4, and finally use hoisting equipment to lift the straight roller mechanism off the machine tool station to complete the entire processing process.

[0045] The installation of straight rollers on mercerizing machines requires no major modifications to the machine tool, making it highly adaptable.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
