Problems solved by technology

[0003] First, the structural cost is high. Generally, the left oil return sleeve 5 and the right oil return sleeve 6 are made of alloy steel, which is costly;
[0004] Second, the processing and assembly requirements are high, mainly because the positional relationship between the oil return tank 7 and the casing 4 is high, assembly is inconvenient, and oil leakage is prone to occur

Embodiment 1

[0033] Embodiment 1: see image 3 -5:

[0034] An oil-proof type wire-making cam structure, the wire-making camshaft 10 is arranged in the casing 20, in order to make the rotation flexible, the wire-making camshaft 10 is supported in the casing 20 through bearings. The casing 20 includes an oil zone 30 and an oil-free zone 40. The camshaft 10 for threading runs through the oil zone 30, and the camshaft 10 for threading in the oil zone 30 is covered with an oil retaining sleeve 50. The two ends are sealed and connected with the casing 20, so that the wire-strapping camshaft 10 can be completely isolated in the oily area 30, so that the oil in the oily area 30 will not touch the wire-strapping camshaft 10, thereby preventing the oily area 30 from The oil inside leaks to the outside of the casing 20 or the oil-free zone 40, and the oil-proof effect is good.

[0035] The housing 20 is provided with installation holes for the oil deflector sleeve, and the outer surfaces of both e...

Embodiment 2

[0046] Embodiment two: see Figure 6 , 7 :

[0047] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0048] The casing 20 is provided with installation holes for oil retaining sleeves, the one far away from the oil-free area 40 is the oil retaining sleeve installation hole one, and the one close to the oil-free area 40 is the oil retaining sleeve installation hole two 90, and the oil retaining sleeve 50 is close to the oil retaining sleeve The outer diameter of one end of the sleeve mounting hole 90 is larger than the aperture of the oil retaining sleeve mounting hole 90, and the end surface of the oil retaining sleeve 50 is in sealing connection with the casing inner wall 100 in the oil area 30 where the oil retaining sleeve mounting hole 2 90 is located. , the other end of the oil deflecting sleeve 50 is arranged in the first installation hole of the oil deflector sleeve, and the outer surface of this end is in seali...

Embodiment 3

[0052] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0053] The outer diameter of the oil retaining sleeve corresponding to the end far away from the oil retaining sleeve installation hole one is larger than the aperture of the oil retaining sleeve installation hole one, and the end surface of the oil retaining sleeve and the oil retaining sleeve installation hole one are located in the casing in the oil area The inner wall is sealed and connected, and the other end of the oil deflecting sleeve is arranged in the second installation hole of the oil deflecting sleeve, and the outer surface of this end is sealed and connected with the second installation hole of the oil deflecting sleeve.

[0054]The end surface of the oil deflecting sleeve away from the installation hole 1 of the oil deflecting sleeve is connected with the corresponding inner wall of the casing through a gasket or through glue sealing. And the aperture...

Abstract

The invention belongs to the technical field of sewing machines and particularly relates to an oil-proof type wire bonding cam structure. A wire bonding cam shaft is arranged in a casing, the casing comprises an oil area and an oil-free area, the wire bonding cam shaft penetrates through the oil area, the wire bonding cam shaft in the oil area is sleeved with an oil stop sleeve, and two ends of the oil stop sleeve are in sealing connection with the casing. The oil stop sleeve penetrates through the whole oil area, the two ends of the oil stop sleeve are mounted on the casing at two ends of the oil area, and the oil stop sleeve is in sealing connection with the casing. The oil area and the oil-free area can be completely isolated, oil in the oil area can be effectively prevented from leaking out of the casing or the oil-free area, and the oil prevention effect is good.

Description

Technical field: [0001] The invention belongs to the technical field of sewing machines, in particular to an oil-proof thread-making cam structure. Background technique: [0002] On the existing platform type interlock sewing machine, there are oil zone 1 and oil-free zone 2 (such as figure 1 , 2 shown). The wire punching camshaft 3 of the external wire punching cam structure crosses the oil zone 1 on the casing 4 . In order to prevent lubricating oil from penetrating from the oil zone 1 to the oil-free zone 2 or the outside of the casing, two oil return sleeves, left oil return sleeve 5 and right oil return sleeve 6, need to be installed at corresponding positions on the casing 4. Two oil return sleeves 5, 6 are located on the casing 4 at the two ends of the oil zone and are sleeved outside the camshaft 3 for threading. Oil return grooves 7 are arranged on the outer surfaces of the two oil return sleeves 5 and 6 to send oil back to the oil zone 1 to prevent oil leakage....
