Technical Field

[0001] The utility model relates to the technical field of a rubber ring and a sheath shell assembly device in a sheath assembly production line, in particular to a rubber ring pressing mechanism and a rubber ring pressing device of the sheath assembly production line. Background Art

[0002] The sheath, also known as the insulating sleeve, is mainly used for the outer insulation and protection of the terminal or the wiring connector or the wiring connection. It is widely used in various electrical wiring harnesses such as wires, electrical appliances, automobiles, motorcycles, air conditioners, washing machines, refrigerators, etc.

[0003] The specific structure of the sheath is as follows Figure 5 As shown, the sheath includes a sheath shell 51, a rubber ring 52 installed inside the sheath shell 51, and a buckle 53 installed inside the sheath shell 51. After the sheath is installed, it can be transported to an assembly factory to assemble the wire harness and the sheath.

[0004] Among them, Figure 6 As shown, the sheath shell 51 and the rubber ring 52 of the sheath are relatively special when assembled. First of all, the side wall of the sheath shell 51 is provided with a sheath notch 511, one side of the inside of the sheath shell 51 is provided with a sheath step 512, and the inside of the sheath shell 51 is provided with a placement groove 513 for installing the rubber ring 52. Secondly, the rubber ring 52 is divided into a hard rubber ring 52 and a soft rubber ring 52. The hard rubber ring 52 has a small deformation and is slightly easier to assemble, but the soft rubber ring 52 has a large deformation and is difficult to assemble.

[0005] Therefore, currently, the sheath shell 51 and the rubber ring 52 of the sheath are still assembled manually. However, in view of the particularity of the assembly of the above two, there are the following difficulties:

[0006] 1. If the rubber ring 52 is a hard rubber ring 52, a certain amount of manual effort is required to press the hard rubber ring 52 into the placement groove 513, which is labor-intensive; (minor defect)

[0007] 2. If the rubber ring 52 is a soft rubber ring 52, the deformation of the soft rubber ring 52 is large. When the soft rubber ring 52 is manually pressed into the placement groove 513, due to the deformation of the soft rubber ring 52 and the obstruction of the sheath step 512, a part of the soft rubber ring 52 always falls on the sheath step 512, making it difficult to press the soft rubber ring 52 into the placement groove 513. (The main defect, and also the key problem to be overcome by the utility model) Utility Model Content

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0037] The following will be combined with the drawings in this embodiment of the utility model to clearly and completely describe the technical solution in this embodiment of the utility model. Obviously, the described embodiment is one embodiment of the utility model, not all embodiments of the utility model. Based on this embodiment of the utility model, all other embodiments of the utility model obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The embodiment of the utility model provides a rubber ring pressing mechanism and a rubber ring pressing device of a sheath assembly production line, and the rubber ring pressing mechanism and the rubber ring pressing device of the sheath assembly production line include the following two aspects:

[0039] First, see Figure 1 to Figure 2 The embodiment of the utility model provides a rubber ring pressing mechanism for a sheath assembly production line, comprising a frame 1, a transverse driving module 23 mounted on the frame 1, a transverse stopper 24 mounted at one end of the transverse driving module 23, a first longitudinal driving module 21 mounted above the transverse driving module 23, and a first pressing rod 22 mounted at one end of the first longitudinal driving module 21, wherein the transverse driving module 23 reciprocates transversely and drives the transverse stopper 24 transversely, and the first longitudinal driving module 21 reciprocates longitudinally and drives the first pressing rod 22, wherein the transverse stopper 24 is used to insert into a sheath notch 511 on the side wall of a sheath shell 51, block a sheath step 512 inside the sheath shell 51, and prevent the rubber ring 52 from being pressed into the sheath step 512, and wherein the first pressing rod 22 is used to press the rubber ring 52 into a placement groove 513 inside the sheath shell 51.

[0040] The rubber ring pressing mechanism of the sheath assembly production line also includes a fixed guide 25 installed at one end of the transverse driving module 23, and the transverse block 24 passes through and is slidably connected to the fixed guide 25. The fixed guide 25 plays a role in ensuring the accurate and stable positioning of the transverse block 24 when working. First of all, the reason for ensuring the accurate positioning of the transverse block 24 when working is that the transverse block 24 is used to be inserted into the sheath notch 511 of the side wall of the sheath shell 51. Accurate positioning can avoid interference or friction between the transverse block 24 and the side wall of the sheath shell 51, and avoid the appearance of the sheath shell 51 as a defective product; secondly, the transverse block 24 is used to block the sheath step 512 inside the sheath shell 51 when working. At this time, it will be interfered by the force of the rubber ring 52 or the first pressing rod 22. At this time, it is necessary to ensure the stability of the transverse block 24 to avoid the occurrence of poor assembly.

[0041] A transition chamfer 241 is provided at the top of one end of the transverse stopper 24. During the process of pressing the rubber ring 52 of the rubber ring pressing mechanism 2, the transition chamfer 241 facilitates the rubber ring 52 to slide smoothly into the placement groove 513 of the sheath shell 51.

[0042] The bottom of the first pressing rod 22 has an inner ring stopper 221. During the pressing process of the rubber ring 52 of the rubber ring pressing mechanism 2, the inner ring stopper 221 is inserted into the inner ring of the rubber ring 52 to prevent the rubber ring 52 from deforming, and prevent the rubber ring 52 from being deformed and pressed into the placement groove 513. (If the rubber ring 52 is deformed and pressed into the placement groove 513, then even if the rubber ring 52 is pressed tightly in the placement groove 513, the rubber ring 52 still cannot recover by its own elastic force, and it will be judged as a defective product.)

[0043] The transverse driving module 23 and the first longitudinal driving module 21 are both cylinders.

[0044] Furthermore, the transverse drive module 23 is a precision slide cylinder, and the first longitudinal drive module 21 is a double-axis cylinder or a triple-axis cylinder. The precision slide cylinder can provide tighter displacement and ensure stability; the double-axis cylinder or the triple-axis cylinder ensures the press-in stability and the first press-in rod 22 does not tilt.

[0045] Second, see Figure 3 to Figure 4 An embodiment of the utility model provides a rubber ring pressing device for a sheath assembly production line, comprising a rubber ring pressing mechanism for a sheath assembly production line as described in the first aspect and a rubber ring pressing mechanism 3 installed on one side of the rubber ring pressing mechanism 2, wherein the rubber ring pressing mechanism 3 comprises a second longitudinal driving module 31 installed on one side of the first longitudinal driving module 21 and a second pressing rod 32 installed at one end of the second longitudinal driving module 31, wherein the second longitudinal driving module 31 longitudinally reciprocates and drives the second pressing rod 32, and the second pressing rod 32 is used to press the rubber ring 52 located on the placement groove 513 onto the placement groove 513.

[0046] The rubber ring pressing device of the sheath assembly production line also includes a connecting plate 4, which is connected to one end between the first longitudinal driving module 21 and the second longitudinal driving module 31, and the first pressing rod 22 and the second pressing rod 32 are respectively installed on the connecting plate 4. The function of the connecting plate 4 is equivalent to connecting the first longitudinal driving module 21, the second longitudinal driving module 31, the first pressing rod 22 and the second pressing rod 32 together, further improving the pressing stability of the first pressing rod 22 and the second pressing rod 32, and ensuring that the first pressing rod 22 and the second pressing rod 32 work synchronously, which is convenient for automated synchronous production work.

[0047] At this time, the length of the second pressing rod 32 is greater than that of the first pressing rod 22. The first pressing rod 22 plays a role in pressing the rubber ring 52 in, and the second pressing rod 32 plays a role in pressing the rubber ring 52 into place.

[0048] The second longitudinal drive module 31 is a cylinder. Further, the second longitudinal drive module 31 is a double-axis cylinder or a three-axis cylinder.

[0049] The working principle of the rubber ring pressing device of a sheath assembly production line in an embodiment of the utility model is as follows:

[0050] S1: Figure 6 As shown, in the sheath assembly production line, after the rubber ring 52 is placed inside the sheath shell 51, the sheath assembly production line transports the sheath shell 51 with the rubber ring 52 placed therein to the rubber ring 52 pressing station. At this time, the rubber ring 52 pressing station is located below a rubber ring pressing mechanism of the sheath assembly production line;

[0051] S2: A rubber ring pressing mechanism of a sheath assembly production line presses the rubber ring 52 into the placement groove 513 inside the sheath shell 51, as follows:

[0052] S21: The transverse driving module 23 transversely drives the transverse block 24 to be inserted into the sheath notch 511 on the side wall of the sheath housing 51 (if the rubber ring 52 is partially located in the sheath step 512, the transverse block 24 pushes the rubber ring 52 away from the sheath step 512). Then, the transverse block 24 blocks the sheath step 512 inside the sheath housing 51 to prevent the rubber ring 52 from falling into the sheath step 512.

[0053] S22: The first longitudinal driving module 21 longitudinally drives the first pressing rod 22, the bottom of the first pressing rod 22 contacts the top of the rubber ring 52, the inner ring block 221 is located in the inner ring of the rubber ring 52 to prevent the inner ring of the rubber ring 52 from deforming, and one end of the rubber ring 52 slides along the transition chamfer 241 of the transverse block 24 and one end of the transverse block 24, and is then pressed into the placement groove 513 of the sheath shell 51; (such as Figure 7 As shown) (If there is no transition chamfer 241, the rubber ring 52 is easily deformed or damaged by the extrusion between the first pressing rod 22 and the transverse stopper 24)

[0054] S23: the first longitudinal driving module 21 longitudinally drives the first pressing rod 22 away from the rubber ring 52, and the transverse driving module 23 transversely drives the transverse stopper 24 away from the sheath housing 51;

[0055] S3: The sheath assembly production line transports the rubber ring 52 pressing station to the bottom of the rubber ring pressing mechanism 3;

[0056] S4: The rubber ring pressing mechanism 3 drives the second pressing rod 32 longitudinally through the second longitudinal driving module 31, and the second pressing rod 32 presses and presses the rubber ring 52 into the placement groove 513 of the sheath shell 51. Figure 8 (shown)

[0057] The advantage of the rubber ring pressing mechanism of the sheath assembly production line of the first aspect mentioned above is that: if the rubber ring 52 is a hard rubber ring 52, it has the advantages of automated pressing and reduced labor intensity. Furthermore, if the rubber ring 52 is a soft rubber ring 52, it has the advantage of being easy to press the rubber ring 52 into the placement groove 513 of the sheath shell 51. The rubber ring pressing mechanism 2 can be used as a semi-automatic production, auxiliary manual assembly production or fully automatic production of the sheath assembly production line.

[0058] The rubber ring pressing device of the sheath assembly production line according to the second aspect has the advantages of automatic pressing and pressing of the rubber ring 52 , and can be organically coordinated with the sheath assembly production line to facilitate batch automated production of the sheaths.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
