Abstract
Description
Technical Field
[0001] This utility model belongs to the field of screw sleeve manufacturing equipment, and in particular relates to a screw sleeve assembly tooling. Background Technology
[0002] The assembly of threaded sleeves involves inserting the locking key into the sleeve groove. Traditional assembly methods require pre-installing the locking key into the sleeve and then using a weight to ensure it is at the correct size. This process not only extends the production cycle and increases costs but also affects the product's appearance quality, and positioning is difficult. Because positioning the threaded sleeve during assembly is challenging, relying solely on manual control makes it difficult to meet post-assembly dimensional and testing requirements. Furthermore, the assembled shape cannot be guaranteed to be consistent, and gaps may exist at the assembly points, making it unsuitable for production. Utility Model Content

[0008] The positioning mold is detachably disposed in the second straight hole, and the lower surface of the positioning mold is provided with a mounting hole for installing a locking key.
[0009] Furthermore, the screw assembly tooling also includes a mandrel, and the lower die is provided with a third straight hole that penetrates the lower die vertically. One end of the mandrel is connected to the bottom of the first groove, and the mandrel is detachably disposed in the third straight hole.
[0010] Furthermore, the lower surface of the lower mold is provided with a second groove, and the other end of the third straight hole is connected to the bottom of the second groove.
[0011] Furthermore, the first straight hole and the third straight hole are coaxial.
[0012] Furthermore, the upper mold and the lower mold are detachably connected by a first pin.
[0013] Furthermore, both the upper and lower molds are cylindrical structures, and the outer surface of the cylindrical structure is provided with a supporting part.
[0014] Furthermore, the outer wall of the positioning mold is provided with a vertical V-shaped groove, and the inner wall of the second straight hole is provided with a protrusion that matches the V-shaped groove.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0035] like Figures 1 to 8 As shown, this utility model discloses a screw assembly tooling.
[0036] like Figure 1As shown, the outer wall of the screw sleeve 1 is provided with a screw sleeve groove 101 extending along its axial direction. The screw sleeve 1 is assembled by inserting the locking key 2 into the screw sleeve groove 101.
[0037] like Figure 2 and Figure 3 The aforementioned screw assembly tooling includes an upper mold 4, a lower mold 3, a positioning block 6, and a positioning mold 5.
[0038] like Figure 4 As shown, the upper surface of the lower mold 3 is provided with a first groove 301, and the positioning block 6 is detachably disposed in the first groove 301. The shape and size of the first groove 301 are adapted to the positioning block 6 to achieve fixed positioning of the positioning block 6. For example, after the positioning block 6 is assembled into the first groove 301, the lower surface of the positioning block 6 is in contact with the bottom of the first groove 301, the upper surface of the positioning block 6 is flush with the upper surface of the lower mold 3, and the side surface of the positioning block 6 is in contact with the side wall of the groove.
[0039] The positioning block 6 is provided with a first straight hole that runs vertically through the positioning block 6. Specifically, one end of the first straight hole extends to the upper surface of the positioning block 6, and the other end of the first straight hole extends to the lower surface of the positioning block 6.
[0040] like Figure 5 As shown, a limiting block 601 adapted to the threaded sleeve groove 101 is provided on the inner wall of the first straight hole. When the threaded sleeve 1 is placed in the first straight hole, all the limiting blocks 601 can be simultaneously engaged in the threaded sleeve groove 101, thereby fixing the threaded sleeve 1. The height of the limiting block 601 is determined according to the length of the locking key 2 inserted into the threaded sleeve groove 101. For example, the height of the limiting block 601 is designed such that when the locking key 2 is inserted into the threaded sleeve groove 101 and contacts the limiting block 601 inserted into the threaded sleeve groove 101, the length of the locking key 2 in the threaded sleeve groove 101 meets the assembly dimension requirements. In this embodiment, the limiting block 601 can not only fix the threaded sleeve 1, but also position the length of the locking key 2 inserted into the threaded sleeve groove 101, improving the assembly accuracy.
[0041] The upper mold 4 is detachably mounted on the upper surface of the lower mold 3. The upper mold 4 has a second straight hole that extends vertically through it. Specifically, one end of the second straight hole extends to the upper surface of the upper mold 4, and the other end extends to the lower surface of the upper mold 4.
[0042] The positioning mold 5 is detachably disposed in the second straight hole, and the lower surface of the positioning mold 5 is provided with a mounting hole for installing the locking key 2.
[0043] The position distribution of the mounting holes corresponds to the position distribution of the threaded sleeve grooves 101 on the threaded sleeve 1. That is, after the same number of locking keys 2 as the threaded sleeve grooves 101 are installed into the corresponding mounting holes, these locking keys 2 can be installed into the corresponding threaded sleeve grooves 101 at one time, which improves the assembly efficiency of the threaded sleeve 1.
[0044] In this embodiment, when assembling the locking key 2 and the screw sleeve 1, the assembly fixture is first disassembled into individual parts. Then, the positioning block 6 is installed into the first groove 301 of the lower mold 3, and the screw sleeve 1 is installed into the first straight hole on the positioning block 6. The screw sleeve 1 is fixed by the limiting block 601 in the first straight hole. Then, the upper mold 4 is assembled on the upper surface of the lower mold 3. The locking key 2 is then installed into the corresponding locking key 2 mounting hole on the positioning mold 5. The positioning mold 5 is then installed into the second straight hole on the upper mold 4. The locking key 2 is aligned with the screw sleeve groove 101 on the screw sleeve 1. The positioning mold 5 is moved downward until the locking key 2 contacts the limiting block 601 in the corresponding screw sleeve groove 101. At this time, the locking key 2 is installed in the preset position.
[0045] In some embodiments of this example, the screw assembly tooling further includes a mandrel 7. The lower mold 3 has a third straight hole 302 that extends vertically through the lower mold 3. One end of the third straight hole 302 communicates with the bottom of the first groove 301. The mandrel 7 is detachably disposed within the third straight hole 302. Specifically, one end of the third straight hole 302 extends to the upper surface of the lower mold 3, and the other end extends to the lower surface of the lower mold 3. In these embodiments, the mandrel 7 is used to assist in separating the positioning block 6 and the mandrel 7, thereby facilitating the separation of the product from the positioning block 6 even when the assembly is tight.
[0046] In some embodiments of this example, when the positioning block 6 is located in the first groove 301, the first straight hole and the third straight hole 302 are coaxial.
[0047] In some implementations of this embodiment, such as Figure 6 As shown, the lower surface of the lower mold 3 is provided with a second groove 303, and the other end of the third straight hole 302 is connected to the bottom of the second groove 303.
[0048] In some embodiments of this example, the upper mold 4 and the lower mold 3 are detachably connected by a first pin. For example, the screw-fit fitting further includes a first pin. The upper mold 4 has a fourth straight hole that extends vertically through it, and the lower mold 3 has a fifth straight hole corresponding to the fourth straight hole. One end of the first pin passes through the fourth straight hole and extends into the fifth straight hole, thereby achieving a detachable connection between the upper mold 4 and the lower mold 3. The first pin can be a cylindrical pin. In these embodiments, the first pin serves to position the product and ensure consistent force distribution.
[0049] In some embodiments of this example, the upper and lower surfaces of the lower mold 3 are parallel planar structures, the upper and lower surfaces of the upper mold 4 are parallel planar structures, the upper and lower surfaces of the positioning block 6 are parallel planar structures, and the upper and lower surfaces of the positioning mold 5 are parallel planar structures.
[0050] In some embodiments of this example, after the positioning block 6 is inserted into the first groove 301, the upper surface of the positioning block 6 is flush with the upper surface of the lower mold 3.
[0051] In some embodiments of this example, both the upper mold 4 and the lower mold 3 are cylindrical structures, and the outer surface of the cylindrical structure is provided with a supporting part. For example, the supporting part is a planar structure provided on the outer surface of the cylindrical structure.
[0052] In some embodiments of this example, the outer wall of the positioning mold 5 is provided with a vertical V-shaped groove 501, and the inner wall of the second straight hole is provided with a protrusion 401 that is adapted to the V-shaped groove 501. The positioning mold 5 is limited by the cooperation of the V-shaped groove 501 and the protrusion 401.
[0053] In some embodiments of this example, the positioning mold 5 includes two semi-cylindrical structures, which are connected to form a cylindrical structure by a second pin. The second pin can be a cylindrical pin. In these embodiments, the second pin can control the consistency of pressure during assembly, thereby ensuring consistent assembly dimensions.
[0054] 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.
