Description

Technical Field

[0001] This invention relates to the field of warp knitting machine technology, and in particular to a method for preparing an oiling tool for the comb bar of a warp knitting machine. Background Technology

[0002] Existing warp knitting machines drive the guide needles to complete the looping of yarn in front of the needle and the lateral movement of the needle back through the oscillation between the needles and the lateral movement of the needle back, forming the warp-knitted fabric and giving it a structural variation. The oscillation between the needles of the guide bar is achieved by the rocker arm driving the guide bar guide seat. The guide bar guide seat is fixed with upper and lower ball cages. Corresponding to the guide bar guide seat, each guide bar support is provided along the length of the guide bar. The support is equipped with a rod corresponding to the upper and lower ball cages. The rod moves freely laterally in the ball cage with linear ball bearings. Under the action of the guide bar lateral movement mechanism, the guide bar completes a smooth lateral movement according to the pattern requirements.

[0003] When the yarn corresponding to each guide bar is used up, the guide bar is removed from the guide seat and re-threaded. After threading, a small amount of grease is manually applied to the upper and lower ball cages according to the work requirements to prevent dry friction between the high-speed rotating machine rods and ball cages, which could lead to severe wear and affect the machine's operating accuracy. The guide bar is then reinstalled to resume production. However, manually applying grease to the upper and lower ball cages can result in uneven application or even missed areas, causing dry friction between the rods and ball cages and accelerating wear between components. Applying grease to the rods is also problematic because the oil seals at both ends of the linear ball bearings in the ball cages prevent the grease from reaching the worn areas of the rods and the ball bearing balls, rendering it ineffective for lubrication. To solve these problems of inconvenient and uneven grease application and the tendency to cause oil stains on the fabric, this invention provides a method for preparing a grease application fixture for warp knitting machine guide bars. Summary of the Invention

[0004] This invention discloses an oiling fixture for the comb bar of a warp knitting machine, which mainly solves the problem of inconvenience in oiling the linear ball bearings in the ball cage of the guide seat of the existing warp knitting machine.

[0005] To achieve the aforementioned objective, the technical solution of the present invention is implemented as follows:

[0006] In a first aspect, the present invention provides a lubrication fixture for the comb bar of a warp knitting machine, comprising a connecting part and an oiling part, wherein the connecting part and the oiling part are integrally formed, the connecting part is connected to the output end of a grease gun, the oiling part is provided with an oiling channel communicating with the output end of the grease gun, and along the axial direction of the oiling part, a plurality of sets of oiling holes for linear bearing oiling are passed through the oiling part, the plurality of sets of oiling holes being arranged in a straight line, and the oiling holes communicating with the oiling channel.

[0007] In one embodiment, the multiple sets of oil injection holes are matched with the number of ball rows in the linear bearing.

[0008] In one embodiment, the connecting part is provided with a connecting channel, and the oil injection channel is connected to the grease gun through the connecting channel.

[0009] In one embodiment, the connection channel is provided with a threaded hole that is threadedly connected to the output end of the grease gun.

[0010] In one embodiment, the end of the oil injection portion away from the connecting portion has an arc-shaped structure.

[0011] In one embodiment, the connecting end of the connecting part and the oil injection part is provided with a frustum structure, the end of the frustum structure with a larger diameter is connected to the connecting part, and the end with a smaller diameter is connected to the oil injection part.

[0012] The advantages or beneficial effects of the above technical solution include at least the following: When it is necessary to inject oil into the linear bearing, since the oiling fixture is equipped with a connecting part and an oiling part, after connecting the connecting part to the output end of the grease gun, the oiling part is inserted into the linear bearing through the oiling channel via the output end of the grease gun. Then, the grease is injected into the oiling channel by the grease gun, and the grease is injected into the linear bearing through the oiling hole along the oiling channel. This can prevent the grease from being contaminated by both hands. With the arrangement of multiple oiling holes, it is convenient to add oil, avoid the problems of missing oil or uneven oiling, reduce the wear caused by dry friction between the insert rod and the ball cage, improve the operating efficiency of the warp knitting machine, save the amount of grease used, reduce the waste fabric inevitably generated by grease contamination, and reduce the unit cost of fabric production.

[0013] Secondly, the present invention provides a method for preparing an oiling fixture for a warp knitting machine comb bar, comprising:

[0014] For material selection, use cylindrical steel with a diameter of 25-30 mm and cut it to a length of 80-90 mm;

[0015] The blank is processed by milling a first blank part with a length of 20-30 mm and a diameter of 18-28 mm from the selected cylindrical steel material using a CNC lathe, and a second blank part with a length of 50-70 mm and a diameter of 10-14 mm to obtain the blank part.

[0016] Drill holes: Use a 7 mm drill bit to drill a hole at one end of the first blank part of the blank, with a drilling depth of 60-80 mm, to obtain a connecting channel and an oil injection channel. Then, drill a hole in the second blank part with a 3 mm drill bit to make them interconnected and obtain an oil injection hole.

[0017] After drilling, tap the connecting channel of the first blank part with an M8X1MM tap to make it easier to install oil pipes later.

[0018] Polishing and finishing involves using polishing equipment to polish the surfaces of the first and second blanks after tapping, so that the first blank forms the connecting part and the second blank forms the oil injection part.

[0019] In one embodiment, during the processing of the blank, the diameter of the second blank portion is 12-13 mm and the length is 60-70 mm.

[0020] The advantages or beneficial effects of the above technical solution include at least the following: the processing fixture made by the above preparation method can make the output end of the grease gun threadedly connected to the threaded hole in the connecting channel of the connecting part, and can make the grease injected by the grease gun enter the oil injection channel through the connecting channel, and then be injected into the linear bearing through the oil injection hole, so as to facilitate the application of oil to the linear bearing.

[0034] The names of the messages or information exchanged between the multiple devices in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0035] See Figure 1 and Figure 2 An embodiment of the present invention provides a lubrication fixture for a warp knitting machine comb bar, including a connecting part 1 and an oiling part 2. The connecting part 1 and the oiling part 2 are integrally formed. The connecting part 1 is connected to the output end of a grease gun. The oiling part 2 is provided with an oiling channel 21 that communicates with the output end of the grease gun. Along the axial direction of the oiling part 2, multiple sets of oiling holes for linear bearing oiling pass through the oiling part 2. The multiple sets of oiling holes are formed by multiple oiling holes 22 arranged in a straight line. The oiling holes 22 communicate with the oiling channel 21.

[0036] With the above structure, when it is necessary to lubricate the linear bearing, since the lubrication fixture is equipped with a connecting part 1 and a lubrication part 2, after connecting the connecting part 1 to the output end of the grease gun, the output end of the grease gun communicates with the lubrication channel 21, the lubrication part 2 is inserted into the linear bearing, and then the grease gun injects grease into the lubrication channel 21, so that the grease is injected into the linear bearing through the lubrication hole 22 after passing through the lubrication channel 21. This can prevent the grease from being contaminated by both hands. With the arrangement of multiple lubrication holes 22, it is convenient to lubricate, avoid the problems of leaking grease or uneven grease, reduce the wear caused by dry friction between the insert rod and the ball cage, improve the operating efficiency of the warp knitting machine, save grease consumption, reduce the waste fabric inevitably generated by grease contamination, and reduce the unit cost of fabric production.

[0037] In one embodiment, see Figure 1 and Figure 2 Multiple sets of grease injection holes are matched to the number of ball rows in the linear bearing. In practical applications, by matching multiple sets of grease injection holes to the number of ball rows in the linear bearing, the injected grease can be applied to the ball more quickly, thereby shortening the grease injection time and improving the grease injection effect.

[0038] The connecting part 1 is provided with a connecting channel 11, and the oil filling channel 21 is connected to the grease gun through the connecting channel 11. In practical applications, by providing the connecting channel 11, the connecting channel 11 of the connecting part 1 can be directly connected to the output end of the grease gun, so that when the grease gun is filling, the grease is injected into the oil filling channel 21 through the connecting channel 11.

[0039] The connecting channel 11 is provided with a threaded hole 12 that is threaded to the output end of the grease gun. In practical applications, the output end of the grease gun can be a hollow hose with an external threaded connection end. By connecting the threaded hole 12 to the external thread of the hollow hose, the connecting part 1 can be stably installed on the output end of the grease gun, so as to achieve seamless docking between the grease gun and the grease gun and avoid contaminating the grease with your hands when greasing.

[0040] In one embodiment, see Figure 1 and Figure 2 The end of the oil injection section 2 furthest from the connecting section 1 has an arc-shaped structure 23. In practical applications, by providing an arc-shaped structure 23 at the end of the oil injection section 2, the arc-shaped structure 23 can guide the end of the oil injection section 2 when it is inserted into the linear bearing, making it easier to insert into the linear bearing.

[0041] The connecting end between the connecting part 1 and the oiling part 2 is provided with a frustum structure. The end of the frustum structure with a larger diameter is connected to the connecting part 1, and the end with a smaller diameter is connected to the oiling part 2. In practical applications, the frustum structure at the connecting end of the connecting part 1 and the oiling part 2 allows the oiling part 2 to continue to be pushed into the linear bearing after it is fully inserted, so that the frustum structure abuts against the linear bearing. This ensures that the part can fit tightly against the linear bearing, preventing grease from leaking out during oiling and thus preventing hands from contaminating the grease.

[0042] See Figure 1 and Figure 2 The present invention provides a method for preparing an oiling fixture for a warp knitting machine comb bar, comprising:

[0043] For material selection, use cylindrical steel with a diameter of 25-30 mm and cut it to a length of 80-90 mm;

[0044] Preferably, the diameter is 25 mm and the length is 85 mm;

[0045] The blank is processed by milling a first blank part with a length of 20-30 mm and a diameter of 18-28 mm from the selected cylindrical steel material using a CNC lathe, and a second blank part with a length of 50-70 mm and a diameter of 10-14 mm to obtain the blank part; specifically, the diameter of the second blank part is 12-13 mm and the length is 60-70 mm.

[0046] Preferably, for subsequent polishing, the length of the first blank portion is 25.5 mm and the diameter is 24.5 mm; the length of the second blank portion is 60.5 mm and the diameter is 12.5 mm.

[0047] Drill holes: Use a 7 mm drill bit to drill a hole at one end of the first blank part of the blank, with a drilling depth of 60-80 mm, to obtain the connecting channel 11 and the oil injection channel 21. Drill a hole in the second blank part with a 3 mm drill bit to make their interiors communicate, to obtain the oil injection hole 22.

[0048] Preferably, the drilling depth of the connecting channel 11 and the oil injection channel 21 is 70 mm, and the hole spacing of the oil injection holes 22 is 10 mm.

[0049] Tapping involves tapping the connecting channel 11 of the first blank part with an M8X1MM tap after drilling, to facilitate the later installation of the oil pipe; that is, it refers to the oil pipe at the output end of the grease gun.

[0050] Polishing and finishing: The first and second blanks after tapping are polished by polishing equipment, so that the first blank forms the connecting part 1 and the second blank forms the oil injection part 2.

[0051] Preferably, after the second blank part is surface polished, an oil filling part 2 with a diameter of 12 mm and a length of 60 mm with an error of ±1 mm is obtained. After the first blank part is surface polished, a connecting part 1 with a diameter of 24 mm and a length of 25 mm is obtained. Since the first blank part is the handle part, its polishing error can be ignored.

[0052] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element 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 invention.

[0053] Those skilled in the art should understand that the above embodiments are merely for illustrating the present invention and are not intended to limit the scope of the invention. Those skilled in the art can make other changes or modifications based on the above invention, and these changes or modifications still fall within the scope of the present invention.
