Fixture A is positioned above the fixture A carrier plate, with lead screws on both sides and sliders A positioned at the bottom sides. The machine uses two fixtures for loading and unloading screws sequentially, alternating between the two processes to significantly improve processing efficiency.

[0003] After the bolt is inserted into the bolt sleeve, due to the large gap, the bolt is easy to fall out of the bolt sleeve, which will affect the subsequent connection. Utility Model Content

[0004] The purpose of this invention is to provide a shaping device for assembling expansion bolts, addressing the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A shaping device for assembling expansion bolts includes a rotating disk with multiple push rod assemblies arranged in a ring at equal intervals. A shaping mechanism for radially stamping and shaping bolt sleeves is provided around the rotating disk. The shaping mechanism includes a shaping sleeve through which the bolt sleeves can pass, and a stop structure for supporting the bolt sleeves is provided inside the shaping sleeve. The shaping mechanism also includes a drive shaft radially arranged outside the shaping sleeve. The shaping sleeve has a drive groove radially formed for the drive shaft to be inserted. The shaping sleeve is equipped with a drive connecting rod capable of longitudinal swinging. A drive block that cooperates with the push rod assembly is formed at the top of the drive connecting rod. The drive connecting rod can swing to drive the drive shaft to be inserted into the drive groove of the shaping sleeve.

[0007] Furthermore: the push rod assembly includes a push rod bracket mounted on the top of the rotating disk, a push rod cylinder mounted on the push rod bracket, a push rod post inserted into the push rod cylinder, a push rod block formed at the outer end of the push rod post, and the push rod block being able to contact and engage with the drive block at the top of the drive connecting rod.

[0008] Furthermore, the shaping mechanism also includes a support column for mounting the shaping sleeve. A transverse fixing plate is mounted on the top of the support column. The shaping sleeve is longitudinally fitted onto the transverse fixing plate. A pair of guide bars arranged with gaps are mounted on the transverse fixing plate. The upper part of the drive linkage is located between the two guide bars, and the drive linkage can be guided to move in the area between the two guide bars.

[0009] Furthermore, both the push rod block and the drive block are formed with smooth arc-shaped surfaces.

[0010] Furthermore: the shaping sleeve is provided with a bearing housing for mounting the drive connecting rod, the drive connecting rod is mounted with a pivot shaft that rotates with the bearing housing, and the drive connecting rod swings around the bearing housing via the pivot shaft.

[0011] Furthermore: the drive shaft is fitted with a first compression spring located between the shaping sleeve and the drive block, and the first compression spring can cause the drive shaft to elastically pop outward.

[0012] Furthermore: A connecting rod locating pin is provided below the bearing housing, and the outer end of the connecting rod locating pin abuts against the drive connecting rod.

[0013] Furthermore, a second tension spring is provided below the connecting rod positioning pin. The second tension spring is connected between the drive connecting rod and the shaping sleeve.

[0030] The present invention will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1-3 As shown, a shaping device for assembling expansion bolts includes a rotating disk 1, on which a plurality of push rod assemblies 11 are arranged in a ring at equal intervals. A shaping mechanism 2 for radially punching and shaping bolt sleeves 19 is provided around the rotating disk 1. The shaping mechanism 2 includes a shaping sleeve 21 through which bolt sleeves 19 can pass, and a stop structure for supporting bolt sleeves 19 is provided inside the shaping sleeve 21.

[0032] The shaping mechanism 2 further includes a drive shaft 25 radially arranged on the outside of the shaping sleeve 21. The shaping sleeve 21 is radially formed with a drive groove 26 for the drive shaft 25 to be inserted. The shaping sleeve 21 is equipped with a drive link 3 that can swing longitudinally. The top of the drive link 3 is formed with a drive block 31 that cooperates with the push rod assembly 11. The drive link 3 can swing to drive the drive shaft 25 to be inserted into the drive groove 26 of the shaping sleeve 21.

[0033] After the bolt is inserted into the bolt sleeve 19, in order to make the bolt sleeve 19 and the screw more stable, the bolt sleeve 19 is placed into the shaping sleeve 21 and supported by the stop structure. The rotating disk 1 rotates, and through the push rod assembly 11 and the drive connecting rod 3 of the shaping mechanism 2, the push rod assembly 11 contacts the drive block 31 at the top of the drive connecting rod 3. The drive shaft 25 can be inserted into the shaping sleeve 21 and contact the bolt sleeve 19 inside the shaping sleeve 21 to achieve stamping and shaping. A part of the bolt sleeve 19 will be concave, making the bolt sleeve 19 and the screw more stable and reducing the risk of the screw falling off.

[0034] Specifically, the push rod assembly 11 includes a push rod bracket 12 mounted on the top of the rotating disk 1. The push rod bracket 12 is fitted with a push rod cylinder 13, and a push rod post 14 is inserted into the push rod cylinder 13. A push rod block 15 is formed on the outer end of the push rod post 14, and the push rod block 15 can contact and cooperate with the drive block 31 on the top of the drive connecting rod 3. The rotating disk 1 rotates under the drive of the motor, and the push rod assembly 11 mounted on the rotating disk 1 changes position accordingly. When the outer end of the push rod post 14 mounted on the push rod cylinder 13 is in stop cooperation with the drive block 31 on the top of the drive connecting rod 3, the top of the drive connecting rod 3 will swing outward, and the drive connecting rod 3 will drive the drive shaft 25 to insert into the forming sleeve 21 and contact the bolt sleeve 19 inside the forming sleeve 21, thereby realizing the stamping and forming of the bolt sleeve 19.

[0035] Furthermore, the stop structure includes a first stop plate 17 and a second stop plate 18 radially inserted into the shaping sleeve 21, wherein the distance between the first stop plate 17 and the second stop plate 18 is equal to the length of the bolt sleeve 19. The first stop plate is located above the drive groove 26, and the second stop plate is located below the drive groove 26. In this embodiment, the two bolt sleeves 19 are simultaneously and coaxially inserted into the shaping sleeve 21. Before insertion, the second stop plate 18 is radially inserted into the shaping sleeve 21 to provide stop support for the bottom bolt sleeve 19. At this time, the first stop plate 17 is located at the junction between the two bolt sleeves, and then the first stop plate 18 is inserted into the shaping sleeve 21. The stop plate 17 is radially inserted into the shaping sleeve 21 to support the top bolt sleeve 19 and separate it. After the lower bolt sleeve 19 is shaped, the second stop plate 18 retracts, the lower bolt sleeve 19 falls, and the second stop plate 18 is radially inserted into the shaping sleeve 21. Then the first stop plate 17 retracts, and the upper bolt sleeve 19 falls to be stopped and supported by the second stop plate 18. The first stop plate 17 continues to be radially inserted into the shaping sleeve 21, and the new bolt sleeve 19 can fall into the shaping sleeve 21 and be stopped and supported by the first stop plate 17. This cycle is repeated to stamp and shape the bolt sleeves 19 one by one.

[0036] Preferably, the shaping sleeve 21 is radially formed with a first stop groove 36 through which the first stop plate 17 passes radially and a second stop groove 37 through which the second stop plate 18 passes radially. A first telescopic cylinder 38 that drives the first stop plate 17 to move radially along the first stop groove 36 and a second telescopic cylinder 39 that drives the second stop plate 18 to move radially along the second stop groove 37 are arranged outside the shaping sleeve 21. The first stop groove 36 allows the first stop plate 17 to move radially in a guided manner, thus providing stop support for the bolt sleeve 19. Similarly, the second stop groove 37 allows the second stop plate 18 to move radially in a guided manner, thus providing stop support for the bolt sleeve 19. The radial movement of the first stop plate 17 and the second stop plate 18 can be achieved through the telescopic movement of the first telescopic cylinder 38 and the second telescopic cylinder 39.

[0037] Furthermore, the forming mechanism 2 also includes a support column 22 for mounting the forming sleeve 21. A transverse fixing plate 23 is mounted on the top of the support column 22. The forming sleeve 21 is longitudinally fitted onto the transverse fixing plate 23. A pair of guide bars 24 with gaps are mounted on the transverse fixing plate 23. The upper part of the drive link 3 is located between the two guide bars 24, and the drive link 3 can be guided to move in the area between the two guide bars 24, ensuring that the top of the drive link 3 can be transversely aligned with the drive shaft 25, which facilitates precise stamping and forming of the bolt sleeve 19.

[0038] Furthermore, both the push rod block 15 and the drive block 31 are formed with smooth arc-shaped surfaces 16. The smooth arc-shaped surfaces 16 can reduce the friction between the push rod block 15 and the drive block 31. That is, after the push rod block 15 abuts against the drive block 31 of the drive connecting rod 3, the top of the drive connecting rod 3 swings outward and moves towards the shaping sleeve 21, thereby driving the drive shaft 25 to be inserted into the shaping sleeve 21 to stamp and shape the bolt sleeve 19.

[0039] Preferably, the shaping sleeve 21 is provided with a bearing seat 32 for mounting the drive connecting rod 3. The drive connecting rod 3 is mounted with a fulcrum shaft 33 that rotatably engages with the bearing seat 32. The drive connecting rod 3 swings around the bearing seat 32 via the fulcrum shaft 33. The drive shaft 25 is fitted with a first compression spring 27 located between the shaping sleeve 21 and the drive block 31. The first compression spring 27 can drive the drive shaft 25 to elastically pop outward. Initially, under the elastic drive of the first compression spring 27, the drive shaft 25 pops out towards the rotating disk 1 and will not be inside the shaping sleeve 21, thus not affecting the entry and descent of the bolt sleeve 19. When the top of the drive connecting rod 3 swings towards the shaping sleeve 21, the driving force of the swing is greater than the elastic force of the first compression spring 27, thereby driving the drive shaft 25 to insert into the shaping sleeve 21 and stamp and shape the bolt sleeve 19.

[0040] Preferably, when the angle of swing of the push rod assembly 11 in the direction of the drive link 3 is too large, the push rod block 15 at the outer end of the push rod column 14 cannot contact the drive block 31 at the top of the drive link 3, and the drive link 3 cannot be driven to swing, or the drive link 3 may even be broken or damaged. For this reason, a link positioning pin 34 is provided below the bearing seat 32, and the outer end of the link positioning pin 34 abuts against the drive link 3. The link positioning pin 34 can limit the swing position of the lower half of the drive link 3, prevent the top of the drive link 3 from swinging too large in the direction of the push rod assembly 11, and ensure that each push rod block 15 can contact the drive block 31 at the top of the drive link 3 when the rotating disk 1 is rotating.

[0041] Furthermore, a second tension spring 35 is provided below the connecting rod positioning pin 34. The second tension spring 35 is connected between the drive connecting rod 3 and the forming sleeve 21. The second tension spring 35 can elastically drive the lower half of the drive connecting rod 3 to swing inward toward the forming sleeve 21. After each stamping and forming, there is a gap between two adjacent push rod assemblies 11. At this time, under the combined elastic force of the drive shaft 25 rebounding outward and the second tension spring 35, the top of the drive connecting rod 3 will swing toward the push rod assembly 11 until the push rod block 15 of the next set of push rod assemblies 11 contacts and engages with the drive block 31.

[0042] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0043] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
