The embodiment of the invention provides a drum spring connector assembling device which is used for assembling a drum spring 20 and a needle shaft 10.
Referring to fig. 1, fig. 2 and fig. 5, in an embodiment of the present invention, the drum spring type connector assembling apparatus includes a guiding and pushing member 30 and a pushing cylinder 40. The guiding and pushing member 30 comprises a front end 31 and a rear end 33, the cross section of the front end 31 gradually increases in area along the length direction thereof to form a cone shape, and the drum spring 20 has a first position sleeved on the front end 31 and a second position sleeved on the needle shaft 10; the minimum outer diameter of the front end 31 is not smaller than the outer diameter of the rear end 33, and the maximum outer diameter of the rear end 33 is not larger than the inner diameter of the drum spring 20; the end of the front end 31 away from the rear end 33 is recessed to form a receiving slot 311, and the receiving slot 311 is used for receiving the head 11 of the needle shaft 10. The pushing cylinder 40 is used for pushing the drum spring 20 from the first position to the second position, the pushing cylinder 40 has an accommodating cavity 40a, when the pushing cylinder 40 pushes the drum spring 20, the guiding and pushing member 30 is at least partially located in the accommodating cavity 40a, and an end surface of the pushing cylinder 40 abuts against an end surface of the drum spring 20.
Referring to fig. 3, the front end 31 is partially tapered or entirely tapered. When the front end 31 is tapered as a whole, the front end 31 may be circular truncated cone-shaped or truncated pyramid-shaped. When the front end 31 is in a frustum pyramid shape, the front end 31 can be a frustum pyramid, a frustum pentagon, a frustum hexagon or other frustum pyramids, and the more the edges of the frustum pyramid are, the closer the shape of the front end 31 is to a circular truncated cone; the truncated cone-shaped tip 31 facilitates the assembly of the drum spring 20 and the needle shaft 10, relative to the truncated-pyramid-shaped tip 31; the drum spring 20 is sleeved on the outer wall of the push guide 30, and when the drum spring 20 is pushed by the push cylinder 40, the peripheral wall of the truncated cone-shaped front end 31 exerts an acting force on the periphery of the drum spring 20, and all parts of the inner wall of the drum spring 20 are stressed in a balanced manner, so that the phenomenon that the drum spring 20 is damaged due to uneven stress is avoided.
When the front end 31 is partially tapered, in a direction away from the rear end 33, the outer diameter of the front end 31 gradually increases to a certain extent and then does not change, that is, the front end 31 is composed of a tapered body and a cylindrical body, a portion of the front end 31 close to the rear end 33 is the tapered body, and a portion of the front end 31 away from the rear end 33 is the cylindrical body; for example, a cone or pyramid, and a cylinder or prism. Preferably, the front end 31 is composed of a cone and a cylinder, and the maximum outer diameter of the conical part of the front end 31 is consistent with the outer diameter of the cylindrical part of the front end 31, namely, the difference between the outer diameters is less than 0.0001 mm; the cylindrical portion of the front end 31 is recessed from an end of the tapered portion of the front end 31 to form the receiving groove 311, the receiving groove 311 is a hemispherical groove, and the size of the receiving groove 311 can completely receive the head 11 of the needle shaft 10.
The rear end 33 is cylindrical, conical or a combination of the two, when the rear end 33 is conical, the outer diameter of the rear end 33 gradually decreases in a direction away from the front end 31, the maximum outer diameter of the rear end 33 of the guiding and pushing member 30 is smaller than or equal to the inner diameter of the drum spring 20, preferably, the maximum outer diameter of the rear end 33 is smaller than the inner diameter of the drum spring 20, and the rear end 33 is truncated cone-shaped, truncated pyramid-shaped, conical or pyramid-shaped; when the rear end 33 has a cylindrical shape, the outer diameter of the rear end 33 is smaller than or equal to the inner diameter of the drum spring 20, and preferably, the smaller the outer diameter of the rear end 33 is, the closer the outer diameter of the rear end 33 is to the inner diameter of the end wall of the drum spring 20, the better the guiding effect of the rear end 33 on the drum spring 20 is, but the more easily the two generate relative friction force to hinder the drum spring 20 from moving toward the needle shaft 10, and the more easily the drum spring 20 and the guide and push member 30 are worn. When the rear end 33 is a combination of a cylindrical shape and a conical shape, a portion of the rear end 33 close to the front end 31 is cylindrical, a portion of the rear end 33 far from the front end 31 is conical, and a conical tip is far from a cylindrical portion of the rear end 33. The latter has better guiding function relative to the former two; firstly, the conical portion of the rear end 33 facilitates the sleeving of the drum spring 20 on the outer wall of the guiding and pushing member 30, and secondly, the cylindrical portion of the rear end 33 can play a role in positioning the drum spring 20 so as to enable the drum spring 20 to move axially along the guiding and pushing member 30.
When the drum spring type connector assembling device is used for assembling the drum spring 20 and the needle shaft 10, the drum spring 20 and the guiding and pushing part 30 are assembled together, so that the drum spring 20 is sleeved on the outer wall of the guiding and pushing part 30; then, the guiding and pushing part 30 with the drum spring 20 is assembled with the needle shaft 10, and the head 11 of the needle shaft 10 is placed in the accommodating groove 311; and finally, the drum spring 20 sleeved on the outer wall of the guiding and pushing part 30 is pushed and pushed through the pushing and pushing cylinder 40, and the end surface of the pushing and pushing cylinder 40 is abutted with the end surface of the drum spring 20 far away from the needle shaft 10.
Referring to fig. 4, the pushing cylinder 40 is a cylinder, and the pushing cylinder 40 may be a cylinder, a prism, or other irregular multi-surface cylinder. The accommodating cavity 40a of the pushing cylinder 40 is cylindrical, conical or other irregular shapes. The length of the pushing cylinder 40 is not required, the length of the pushing cylinder 40 may be not less than the length of the pushing guide 30 and may also be less than the length of the pushing guide 30, generally, the length of the pushing cylinder 40 is set to be greater than or equal to the length of the pushing guide 30, so as to facilitate the pushing of the drum spring 20 by the pushing cylinder 40.
The drum spring 20 type connector assembling apparatus can rapidly assemble the drum spring 20 with the needle shaft 10. The head 11 of the needle shaft 10 is convexly provided with a stop table 111, the outer diameter of the stop table 111 is larger than the inner diameter of the drum spring 20 when the drum spring 20 is not expanded, during installation, the drum spring 20 firstly passes through the stop table 111 of the needle shaft 10 and then reaches the installation position of the needle shaft 10, in the process, the drum spring 20 needs to be stressed and expanded to the inner diameter not smaller than the outer diameter of the stop table 111 of the needle shaft 10, and the introduction of the guide and push part 30 reduces the expansion difficulty of the drum spring 20. Because one end of the guiding and pushing member 30 is sleeved on the head 11 of the needle shaft 10, the maximum outer diameter of the guiding and pushing member 30 is larger than the outer diameter of the stop table 111 of the needle shaft 10, the inner diameter of the drum spring 20 when the drum spring is not expanded is larger than the minimum outer diameter of the guiding and pushing member 30, and the drum spring 20 can be easily sleeved on the outer wall of one end of the guiding and pushing member 30; under the action of the pushing cylinder 40, the drum spring 20 moves towards the needle shaft 10 along the outer wall of the pushing guide 30, in the process, only a force towards the needle shaft 10 needs to be applied to the pushing cylinder 40, and the drum spring 20 does not need to be manually broken, so that the risk of finger injury in the assembling process is reduced; in addition, the tapered design of the guiding and pushing member 30 gradually increases the inner diameter of the drum spring 20 to be not smaller than the outer diameter of the stop table 111 of the needle shaft 10, and the force required by the expansion of the drum spring 20 is equally divided into a plurality of parts in the process, so that the difficulty of the expansion of the drum spring 20 is reduced, and the assembly efficiency of the drum spring 20 and the needle shaft 10 is further improved.
Referring to fig. 3, in an embodiment, the maximum outer diameter of the front end 31 is 2.25 to 2.45mm, an included angle between a generatrix or a side edge of the front end 31 and a central axis thereof is α, where α is 3 to 5 °, within the range, the drum spring 20 can be pushed to move toward the needle shaft 10 with a small force, and the length of the guide and push member 30 is suitable, which facilitates to accelerate the assembly speed and save the space required for the assembly. When α is greater than 5 °, the taper of the front end 31 is relatively large, and the larger the taper is, the larger the thrust for pushing the drum spring 20 to move toward the needle shaft 10 is, the more energy is consumed; when α is smaller than 3 °, the taper of the front end 31 is smaller, the smaller the taper is, the longer the length of the guide and push member 30 is, and the larger the space occupied by the drum spring 20 and the needle shaft 10 when assembled is; setting the range of the angle alpha to be 3-5 degrees, the thrust and the length of the guide and push member 30 can be balanced, and then the drum spring 20 and the needle shaft 10 can be quickly assembled.
Referring to fig. 6, 8 and 10, in another embodiment, the pushing cylinder 40 has a plurality of pushing cylinders 40, the inner diameters of the pushing cylinders 40 are different, the pushing cylinders 40 sequentially push the drum spring 20 toward the needle shaft 10 according to the inner diameters from small to large, and different pushing cylinders 40 can push the drum spring 20 to different depths. Generally, the end wall of the drum spring 20 is designed to be thin, the length of the drum spring 20 is 5mm to 7mm, the thickness of the end wall of the drum spring 20 is 0.14mm to 0.16mm, the inner diameter and the outer diameter of the end wall of the drum spring 20 when not expanded are 1.8 mm to 2.0mm and 2.1 mm to 2.3mm, and the outer diameter of the stop 111 of the head 11 of the needle shaft 10 is 2.25 mm to 2.45mm, at this time, a push cylinder 40 may not successfully push the drum spring 20 to the assembly position 13 of the outer wall of the needle shaft 10, if a push cylinder 40 is used for pushing, the inner diameter of the push cylinder 40 should not be smaller than the outer diameter of the stop 111 of the head 11 of the needle shaft 10, because the front end 31 is tapered, the inner diameter of the push cylinder 40 should not be smaller than the maximum outer diameter of the rear end 33, that is, the inner diameter of the push cylinder 40 may cause the push cylinder 40 to be unable to push the end 30 of the push piece, the inner diameter of the pushing cylinder 40 is too large, so that the end surface of the pushing cylinder 40 cannot abut against the end surface of the drum spring 20 and cannot push the drum spring 20. The plurality of pushing cylinders 40 are used for pushing the drum spring 20 in a relay manner, so that the drum spring 20 moves towards the needle shaft 10 and is finally sleeved in the assembling position 13 of the outer wall of the needle shaft 10.
Referring to fig. 7, 9 and 11, in another embodiment based on the above embodiment, the length of the guiding and pushing member 30 is 10.7mm to 15mm, the length of the front end 31 is 5.7 mm to 8mm, and the length of the tapered portion of the front end 31 is 4.3 mm to 4.6 mm; the length of rear end 33 is 5 ~ 7 mm. In addition, the pushing cylinder 40 includes a first pushing cylinder 4140, a second pushing cylinder 4340 and a third pushing cylinder 45, the first pushing cylinder 41 and the second pushing cylinder 43 are all cylindrical cylinders, the outer diameters of the first pushing cylinder 41 and the second pushing cylinder 43 are not less than 2.9mm, the inner diameter of the second pushing cylinder 43 is greater than the inner diameter of the first pushing cylinder 41, and the inner diameter of the third pushing cylinder 45 is greater than the inner diameter of the second pushing cylinder 43. The length of the first pushing cylinder 41 is 12.1-12.2 mm, the first pushing cylinder 41 is provided with a first accommodating cavity 411, the first accommodating cavity 411 is cylindrical, and the diameter of the first accommodating cavity 411 is 1.91-1.89 mm; the length of the second pushing cylinder 43 is 14-14.2 mm, the second pushing cylinder 43 is provided with a second accommodating cavity 431, the second accommodating cavity 431 is cylindrical, and the diameter of the second accommodating cavity 431 is 2.19-2.21 mm; the length of the third pushing cylinder 45 is 17-17.5 mm, the third pushing cylinder 45 is provided with a third accommodating cavity 451, the shape of the third accommodating cavity 451 is similar to that of the outer wall of the guiding and pushing part 30, the third accommodating cavity 451 is composed of a cylinder and a cone, the maximum distance between the third accommodating cavities 451 is 2.25-2.45 mm, the cone structure of the third accommodating cavity 451 plays a role in positioning, and when the third pushing cylinder 45 pushes the drum spring 20 to the assembling position 13 of the outer wall of the needle shaft 10, the cone structure of the accommodating cavity 40a prevents the third pushing cylinder 45 from continuously pushing the drum spring 20.
When the drum spring 20 and the needle shaft 10 are assembled by using the drum spring 20 type connector assembling device, the drum spring 20 and the guiding and pushing member 30 are assembled together, so that the drum spring 20 is sleeved on the outer wall of the guiding and pushing member 30, and at this time, the drum spring 20 cannot move towards the needle shaft 10 without the action of external force; then the guiding and pushing piece 30 with the drum spring 20 is assembled with the needle shaft 10, and the head 11 of the needle shaft 10 is placed in the containing groove 311; when the drum spring 20 is pushed to move towards the needle shaft 10, the drum spring 20 is pushed by the first pushing cylinder 41, the end surface of the first pushing cylinder 41 abuts against the end surface of the drum spring 20, the first pushing cylinder 41 can push the drum spring 20 downward by 5.85-6.05 mm, when the first pushing cylinder 41 continues to push the drum spring 20 downward, the second pushing cylinder 43 is used to push the drum spring 20 downward, the second pushing cylinder 43 can push the drum spring 20 downward by 1.8-2.0 mm, when the second pushing cylinder 43 cannot push the drum spring 20 to move downwards continuously, the third pushing cylinder 45 is used to push the drum spring 20 to move downwards continuously, the third pushing cylinder 45 can push the drum spring 20 downward by 1.75-1.95 mm, the third pushing cylinder 45 just pushes the drum spring 20 to the assembling position 13 of the outer wall of the needle shaft 10. The drum spring 20 and the needle shaft 10 are assembled successfully and quickly by the relay pushing of the first pushing cylinder 41, the second pushing cylinder 43 and the third pushing cylinder 45.
The first pushing cylinder 41, the second pushing cylinder 43 and the third pushing cylinder 45 are consistent in outer diameter, the difference of the outer diameters of the first pushing cylinder, the second pushing cylinder and the third pushing cylinder is smaller than 0.0001mm, the consistent outer diameter is beneficial to assembly process, and the assembly efficiency can be greatly improved. The outer diameters of the first pushing cylinder 41, the second pushing cylinder 43 and the third pushing cylinder 45 are 2.8-3.2 mm; if the outer diameter of the first abutting-pushing cylinder 41, the second abutting-pushing cylinder 43, or the third abutting-pushing cylinder 45 is too small, when the drum spring 20 is abutted, the contact area of the first abutting-pushing cylinder 41, the second abutting-pushing cylinder 43, or the third abutting-pushing cylinder 45 is too small, and the drum spring 20 is easily damaged due to uneven stress because the end wall of the drum spring 20 is thin; if the outer diameter of the first pushing cylinder 41, the second pushing cylinder 43 or the third pushing cylinder 45 is too large, the waste of the material and the waste of the space are easily caused.
Further, the outer walls of the first pushing cylinder 41, the second pushing cylinder 43 and the third pushing cylinder 45 are all convexly provided with annular pushing tables 40b, and the outer diameter of each pushing table 40b is 3.9-4.5 mm. The first abutting cylinder 41, the second abutting cylinder 43 or the third abutting cylinder 45 is pushed to move toward the needle shaft 10 by applying a force to the abutting table 40b, and the drum spring 20 is pushed to move toward the needle shaft 10. The design of the pushing table 40b facilitates pushing the first pushing cylinder 41, the second pushing cylinder 43 or the third pushing cylinder 45.
