Description

Technical Field

[0001] The present invention relates to the field of processing equipment, and particularly relates to a crown spring jack assembly line. Background Art

[0002] A crown spring jack usually consists of a tubular part and a crown spring inserted into the tubular part. It has the characteristics of high reliability, small contact resistance, earthquake resistance, shock resistance, gentle insertion and extraction, etc., and is widely used in large current connection occasions such as new energy. In order to improve the physical and electrical properties of the crown spring jack, generally, a twisting operation needs to be performed on the crown spring, that is, the upper and lower ends of the crown spring are twisted in opposite directions by a certain angle, so that the side wall of the crown spring is in an inwardly concave arc shape. However, the functions of the existing crown spring jack assembly lines are relatively single. Generally, they can only assemble the twisted crown spring, and cannot twist the crown spring while assembling the crown spring jack. It needs to cooperate with other crown spring twisting equipment for operation, which is inconvenient to use. Summary of the Invention

[0003] Based on this, the present invention provides a crown spring jack assembly line, including a frame. A conveyor line is arranged on the frame. Along the conveying direction of the conveyor line on the frame, a first tube inserting mechanism, a second tube inserting mechanism, a twisting mechanism, a first sleeve mechanism, a flipping mechanism, a second sleeve mechanism and a blanking mechanism are sequentially arranged; An inserting fixture is arranged on the conveyor line. The inserting fixture sequentially passes through the first tube inserting mechanism, the second tube inserting mechanism, the twisting mechanism, the first sleeve mechanism, the flipping mechanism, the second sleeve mechanism and the blanking mechanism under the conveying of the conveyor line; The inserting fixture includes a mounting seat fixedly installed on the conveyor line. A cylindrical clamping hole is opened on the mounting seat. The clamping hole is arranged vertically. A slot penetrating the mounting seat is opened at the bottom of the clamping hole. The slot is arranged around the axis of the clamping hole; The twisting mechanism includes a mounting part that is liftably arranged on the frame, and a clamping device that is rotatably arranged on the mounting part.

[0004] The present invention is applicable to the processing of the crown spring jack as Figure 1 shown, which includes a tubular part and a crown spring inserted into the tubular part. Among them, both ends of the crown spring have bifurcations, and the bifurcations at both ends of the crown spring extend out of the ends of the tubular part; The present invention is used to insert the crown spring into the tubular part, and after twisting the crown spring, fold the bifurcations at both ends of the crown spring to fit on the outer side wall of the tubular part, and use a sleeve to fix the folded bifurcations.

[0005] In the present invention, the number of slots at the bottom of the clamping hole is the same as the number of bifurcations of the crown spring, and they are arranged in one-to-one correspondence, so that when the crown spring is inserted into the clamping hole, the bifurcations of the crown spring can be inserted into the corresponding slots to realize the fixation of one end of the crown spring by the clamping hole.

[0006] In the present invention, a conveyor line is used to convey the insertion fixture thereon, so that the insertion fixture sequentially passes through the working stations of the first tube inserting mechanism, the second tube inserting mechanism, the twisting mechanism, the first sleeve mechanism, the flipping mechanism, the second sleeve mechanism and the blanking mechanism; the first tube inserting mechanism is used to insert a tubular part into the clamping hole at its working station; the second tube inserting mechanism is used to insert a crown spring into the tubular part located in the clamping hole at its working station; the twisting mechanism is used to perform a twisting operation on the crown spring located in the tubular part at its working station; the first sleeve mechanism is used to turn the bifurcated end of the crown spring that has been twisted to the outer wall of the tubular part at its working station, and sleeve a sleeve on the turned bifurcated part to fix the bifurcated part on the outer wall of the tubular part; the flipping mechanism is used to turn the tubular part and the crown spring in the clamping hole by 180° at its working station; the second sleeve mechanism is used to turn the bifurcated end of the crown spring that has not been turned to the outer wall of the tubular part at its working station, and sleeve a sleeve on the turned bifurcated part to fix the bifurcated part on the outer wall of the tubular part. Through the cooperative work of each mechanism, the present invention can perform a twisting operation on the crown spring while assembling the crown spring socket, greatly improving the usability of the present invention.

[0007] Wherein, the inner diameter of the clamping hole is preferably the same as the outer diameter of the tubular part, so that the clamping hole can play a role in fixing the tubular part. At the same time, when the inner diameter of the clamping hole is the same as the outer diameter of the tubular part, a widening hole with the same outer diameter as the sleeve needs to be provided above the inner side of the clamping hole to accommodate the sleeve during the sleeve operation of the first sleeve mechanism, and to accommodate and fix the sleeve in the widening hole after the flipping mechanism flips the tubular part.

[0008] Furthermore, the first tube inserting mechanism, the second tube inserting mechanism, the first sleeve mechanism and the second sleeve mechanism all include a conveying track fixedly arranged on the frame, and a first gripper arranged on the frame through a displacement mechanism; a grasping position is formed at one end of the conveying track facing the conveyor line, and the first gripper is correspondingly arranged at the grasping position.

[0009] Wherein, the conveying track of the first tube inserting mechanism is used to connect the feeding mechanism of the tubular part and convey the received tubular part to the grasping position thereon; the conveying track of the second tube inserting mechanism is used to connect the feeding mechanism of the crown spring and convey the received tubular part to the grasping position thereon; the conveying tracks of the first sleeve mechanism and the second sleeve mechanism are used to connect the feeding mechanism of the sleeve and convey the received sleeve to the grasping position thereon.

[0010] Among them, the working process of the first inserting tube mechanism is as follows: when the conveying line transfers the inserting fixture to the working station of the first inserting tube mechanism, the first gripper of the first inserting tube mechanism grabs the tubular part at the grasping position of the first inserting tube mechanism to the inserting fixture, and inserts the tubular part into the clamping hole of the inserting fixture;

[0011] The working process of the second inserting tube mechanism is as follows: when the conveying line transfers the inserting fixture with the tubular part inserted to the working station of the second inserting tube mechanism, the first gripper of the second inserting tube mechanism grabs the crown spring at the grasping position of the second inserting tube mechanism to the inserting fixture, and inserts the crown spring into the tubular part. At the same time, the bifurcations of the crown spring are inserted into the slots at the bottom of the clamping hole to fix the crown spring on the clamping hole. Among them, in order to align the bifurcations of the crown spring with the slots and insert the crown spring into the clamping hole, an angle adjusting device or manual adjustment can be used at the grasping position of the conveying track to adjust the angle of the crown spring so that the positions of the bifurcations of the crown spring correspond to the positions of the slots in the clamping hole one by one.

[0012] Furthermore, the second inserting tube mechanism further includes a limiting part. A limiting hole penetrating the limiting part is provided on the limiting part. The limiting hole is in the shape of an inverted truncated cone. The limiting part is arranged on the frame through a displacement mechanism.

[0013] Among them, the inner diameter of the lower end of the limiting hole is the same as the outer diameter of the crown spring. When the second inserting tube mechanism inserts the crown spring into the clamping hole, by moving the limiting hole so that the axis of the limiting hole and the axis of the clamping hole are on the same vertical line, the limiting hole can play a role in limiting and guiding the crown spring. When the bifurcations of the crown spring are bent outwards, the limiting hole can straighten and repair the bifurcations of the crown spring, and further ensure that the crown spring can be smoothly inserted into the tubular part in the clamping hole.

[0014] Furthermore, the first sleeve mechanism and the second sleeve mechanism further include a folding mechanism. The folding mechanism includes a vertically arranged top column. The top column is arranged on the frame in a liftable manner. A spreading part in the shape of an inverted truncated cone is arranged at the lower end of the top column.

[0015] Among them, the diameter of the lower end of the spreading part is smaller than the inner diameter of the crown spring, and the diameter of the upper end of the spreading part is larger than the inner diameter of the crown spring and larger than the outer diameter of the sleeve.

[0016] Among them, the working process of the first sleeve mechanism is as follows: when the conveying line transfers the inserting fixture with the tubular part and the crown spring inserted to the working station of the first sleeve mechanism, the first gripper of the first sleeve mechanism grabs the sleeve at the grasping position of the corresponding conveying track above the tubular part. Then the top column moves downward, so that the outer side surface of the top column spreads the bifurcations of the crown spring. Then the first gripper grabs the sleeve and moves downward to tightly sleeve the bifurcations of the crown spring on the outer side wall of the tubular part. At this time, the sleeve operation at one end of the tubular part is completed.

[0017] The working process of the second sleeve mechanism is as follows: when the inserting jig with tubular parts and crown springs is transferred by the waiting conveyor line to the working station of the second sleeve mechanism, the first gripper of the second sleeve mechanism grabs the sleeve at the grasping position of the corresponding conveying track above the tubular part, and then the ejector rod moves downward, so that the outer side surface of the ejector rod expands the fork of the crown spring, and then the first gripper holds the sleeve and moves downward to tightly sleeve the fork of the crown spring on the outer wall of the tubular part. At this time, the sleeve operation of the other end of the tubular part is completed.

[0018] Further, an extension part is arranged at the bottom of the expanding part, and the diameter of the extension part decreases successively from top to bottom.

[0019] Among them, when the extension part of the expanding part generates an inward bend at the fork of the crown spring, it can ensure that the expanding part can extend into the crown spring, so as to ensure that all forks of the crown spring can be expanded by the expanding part.

[0020] Further, the conveying track includes a conveying strip, a conveying groove is arranged on the conveying strip along the length direction of the conveying strip, and a receiving groove is arranged on the upper surface of one end of the conveying strip facing the conveyor line along the vertical direction of the conveying strip. The receiving groove is communicated with the conveying groove, and both ends of the receiving groove extend out of the conveying strip to form a grasping position; the first gripper is a flat gripper cylinder.

[0021] Among them, the grasping position is a receiving groove extending out of both ends of the conveying strip, which can facilitate the flat gripper cylinder to directly grasp the tubular part, crown spring and sleeve located in the conveying groove.

[0022] Further, the clamping device includes a vertically arranged cylindrical inserting rod, and a plurality of vertically arranged clamping strips are arranged on the outer side wall of the inserting rod. The clamping strips protrude from the surface of the inserting rod and are evenly arranged around the inserting rod, and the number of the clamping strips is the same as the number of the inserting slots; the flipping mechanism includes a mounting seat which is arranged on the frame in a liftable manner, and a second gripper is arranged on the mounting seat. The second gripper is arranged on the mounting seat in a horizontally flippable manner.

[0023] Among them, the clamping method of the clamping device for the fork of the crown spring is as follows: first, the inserting rod moves downward to be inserted into the crown spring. At this time, since the position of the fork of the crown spring is fixed, the clamping strips on the inserting rod will be embedded between two adjacent forks, and then, by rotating the inserting rod, the twisting of the fork of the crown spring can be realized, and further the twisting of the crown spring can be realized.

[0024] Among them, the second gripper of the flipping mechanism can be a cylinder gripper. After the second gripper grabs the tubular part, it can turn the tubular part upside down by 180° through its horizontal flipping.

[0025] In addition, during the process of inserting the crown spring into the clamping hole, it is not necessary to care whether the bifurcations of the crown spring are inserted into the slots. Instead, the bifurcations of the crown spring can be inserted into the slots through a torsion mechanism to fix the crown spring. For example, the part of the bottom of the clamping hole located between two adjacent slots is made into a convex platform shape to form a sliding part, and the cross-section of the convex platform-shaped part in the direction perpendicular to the radial direction of the clamping hole is made into a semicircle, that is, the surface of the convex platform-shaped part will bend downward towards the slots on both sides. At this time, when the torsion mechanism moves downward towards the crown spring to twist the crown spring, after the torsion mechanism abuts against the crown spring, the horizontal component force generated by the pressure applied to the crown spring will cause the bifurcations of the crown spring abutting against the sliding part to slide along the surface of the sliding part into the slots, so that the crown spring is fixed in the clamping hole.

[0026] Furthermore, the blanking mechanism includes a third gripper arranged on the frame through a displacement mechanism.

[0027] After the crown spring socket is assembled, the crown spring socket can be moved from the assembly jig to a preset position through the third gripper, completing the blanking operation of the crown spring socket.

[0028] The principle and effects of the present invention will be further described below in combination with the above technical solutions and the drawings:

[0029] By opening slots at the bottom of the clamping hole for the bifurcations of the crown spring to insert and clamp the bifurcations of the crown spring, the present invention enables the crown spring to be fixed in the clamping hole, allowing the torsion mechanism to twist the entire crown spring by twisting one end of the crown spring, thus smoothly performing the torsion operation on the crown spring. That is, the present invention can twist the crown spring while assembling the crown spring socket, greatly improving the convenience of use of the present invention.

[0040] For the convenience of those skilled in the art to understand, the present invention will be further described in detail below in conjunction with the drawings and embodiments:

[0041] The present invention is applicable to the processing of a crown spring jack as shown in Figure 1 , which includes a tubular part a and a crown spring b inserted into the tubular part a. Among them, both ends of the crown spring b have bifurcations b1, and the bifurcations b1 at both ends of the crown spring b extend out of the ends of the tubular part a; the present invention is used to insert the crown spring b into the tubular part a, and after twisting the crown spring b, the bifurcations b1 at both ends of the crown spring b are folded to fit on the outer side wall of the tubular part a, and the folded bifurcations b1 are fixed with a sleeve c

[0042] The present invention provides a crown spring jack assembly line, as shown in Figures 2 - 8, which includes a frame 1, on which a conveyor line 2 is provided. Along the conveying direction of the conveyor line 2 on the frame 1, a first inserting tube mechanism 3, a second inserting tube mechanism 4, a twisting mechanism 5, a first sleeving mechanism 6, a flipping mechanism 7, a second sleeving mechanism 8 and a blanking mechanism 9 are sequentially arranged; an inserting fixture 21 is arranged on the conveyor line 2, and the inserting fixture 21 sequentially passes through the first inserting tube mechanism 3, the second inserting tube mechanism 4, the twisting mechanism 5, the first sleeving mechanism 6, the flipping mechanism 7, the second sleeving mechanism 8 and the blanking mechanism 9 under the conveying of the conveyor line 2; the inserting fixture 21 includes a mounting seat fixedly installed on the conveyor line 2, and a cylindrical clamping hole 211 is opened on the mounting seat. The clamping hole 211 is vertically arranged, and a slot 213 penetrating through the mounting seat is opened at the bottom of the clamping hole 211. The slot 213 is arranged around the axis of the clamping hole 211; the twisting mechanism 5 includes a mounting part 111 that is liftably arranged on the frame 1, and a clamping device 112 that is rotatably arranged on the mounting part 111.

[0043] In the present invention, the number of slots 213 at the bottom of the clamping hole 211 is the same as the number of bifurcations b1 of the crown spring b, and they are arranged in one-to-one correspondence, so that when the crown spring b is inserted into the clamping hole 211, the bifurcations b1 of the crown spring b can be inserted into the corresponding slots 213 to realize the fixation of one end of the crown spring b by the clamping hole 211.

[0044] In the present invention, the conveyor line 2 is used to convey the inserting fixture 21 thereon, so that the inserting fixture 21 sequentially passes through the working stations of the first inserting tube mechanism 3, the second inserting tube mechanism 4, the twisting mechanism 5, the first sleeving mechanism 6, the flipping mechanism 7, the second sleeving mechanism 8 and the blanking mechanism 9; the first inserting tube mechanism 3 is used to insert the tubular part a into the clamping hole 211 at its working station; the second inserting tube mechanism 4 is used to insert the crown spring b into the tubular part a located in the clamping hole 211 at its working station; the twisting mechanism 5 is used to perform a twisting operation on the crown spring b located in the tubular part a at its working station; the first sleeving mechanism 6 is used to turn the bifurcations b1 at the end where the crown spring b has been twisted to the outer wall of the tubular part a at its working station, and sleeved the sleeve c on the turned bifurcations b1 to fix the bifurcations b1 on the outer wall of the tubular part a; the flipping mechanism 7 is used to perform a 180° orientation adjustment on the tubular part a and the crown spring b in the clamping hole 211 at its working station; the second sleeving mechanism 8 is used to turn the bifurcations b1 at the end of the crown spring b that has not been turned to the outer wall of the tubular part a at its working station, and sleeved the sleeve c on the turned bifurcations b1 to fix the bifurcations b1 on the outer wall of the tubular part a. Through the cooperative work of each mechanism in the present invention, the present invention can perform a twisting operation on the crown spring b while assembling the crown spring socket, greatly improving the use convenience of the present invention.

[0045] Among them, the inner diameter of the clamping hole 211 is preferably the same as the outer diameter of the tubular part a, so that the clamping hole 211 can play a role in fixing the tubular part a. At the same time, when the inner diameter of the clamping hole 211 is the same as the outer diameter of the tubular part a, a widening hole 212 with the same outer diameter as the sleeve c needs to be provided above the inner side of the clamping hole 211 to accommodate the sleeve c when the first sleeve mechanism 6 performs the sleeve c operation, and to accommodate the tubular part a after the flipping mechanism 7 flips the tubular part a, and fix the sleeve c in the widening hole 212.

[0046] Furthermore, the first intubation mechanism 3, the second intubation mechanism 4, the first sleeve mechanism 6 and the second sleeve mechanism 8 all include a conveying track 101 fixedly arranged on the frame 1, and a first gripper 104 arranged on the frame 1 through a displacement mechanism; a grasping position is formed at one end of the conveying track 101 facing the conveying line 2, and the first gripper 104 is arranged corresponding to the grasping position.

[0047] Among them, the conveying track 101 of the first intubation mechanism 3 is used to connect the feeding mechanism of the tubular part a, and convey the received tubular part a to the grasping position thereon; the conveying track 101 of the second intubation mechanism 4 is used to connect the feeding mechanism of the crown spring b, and convey the received tubular part a to the grasping position thereon; the conveying tracks 101 of the first sleeve mechanism 6 and the second sleeve mechanism 8 are used to connect the feeding mechanism of the sleeve c, and convey the received sleeve c to the grasping position thereon.

[0048] Among them, the working process of the first intubation mechanism 3 is as follows: when the conveying line 2 transfers the insertion jig 21 to the working station of the first intubation mechanism 3, the first gripper 104 of the first intubation mechanism 3 grabs the tubular part a at the grasping position of the first intubation mechanism 3 to the insertion jig 21, and inserts the tubular part a into the clamping hole 211 of the insertion jig 21;

[0049] The working process of the second intubation mechanism 4 is as follows: when the conveying line 2 transfers the insertion jig 21 with the inserted tubular part a to the working station of the second intubation mechanism 4, the first gripper 104 of the second intubation mechanism 4 grabs the crown spring b at the grasping position of the second intubation mechanism 4 to the insertion jig 21, and inserts the crown spring b into the tubular part a, and at the same time makes the fork b1 of the crown spring b insert into the slot 213 at the bottom of the clamping hole 211 to fix the crown spring b on the clamping hole 211. Among them, in order to insert the crown spring b into the clamping hole 211 with the fork b1 of the crown spring b aligned with the slot 213, an angle adjusting device or manual adjustment can be used at the grasping position of the conveying track 101 to adjust the angle of the crown spring b, so that the position of the fork b1 of the crown spring b corresponds to the position of the slot 213 in the clamping hole 211 one by one.

[0050] Further, the second insertion tube mechanism 4 further includes a limiting part 41. A limiting hole 411 penetrating through the limiting part 41 is formed on the limiting part 41. The limiting hole 411 is in the shape of an inverted frustum of a cone. The limiting part 41 is arranged on the frame 1 through a displacement mechanism.

[0051] Wherein, the inner diameter of the lower end of the limiting hole 411 is the same as the outer diameter of the crown spring b. When the second insertion tube mechanism 4 inserts the crown spring b into the clamping hole 211, by moving the limiting hole 411 until the axis of the limiting hole 411 and the axis of the clamping hole 211 are on the same vertical line, the limiting hole 411 can play a role in limiting and guiding the crown spring b. When the bifurcations b1 of the crown spring b are bent outwards, the limiting hole 411 can straighten and repair the bifurcations b1 of the crown spring b, and further ensure that the crown spring b can be smoothly inserted into the tubular part a in the clamping hole 211.

[0052] Further, the first sleeve mechanism 6 and the second sleeve mechanism 8 further include a folding mechanism. The folding mechanism includes a vertically arranged ejector pin. The ejector pin is arranged on the frame 1 in a liftable manner. A spread part in the shape of an inverted frustum of a cone is arranged at the lower end of the ejector pin.

[0053] Wherein, the diameter of the lower end of the spread part is smaller than the inner diameter of the crown spring b, and the diameter of the upper end of the spread part is larger than the inner diameter of the crown spring b and larger than the outer diameter of the sleeve c.

[0054] Wherein, the working process of the first sleeve mechanism 6 is as follows: when the conveying line 2 transfers the insertion jig 21 with the tubular part a and the crown spring b inserted therein to the working station of the first sleeve mechanism 6, the first gripper 104 of the first sleeve mechanism 6 grabs the sleeve c at the grabbing position of the corresponding conveying track 101 above the tubular part a. Then the ejector pin moves downward, so that the outer side surface of the ejector pin spreads the bifurcations b1 of the crown spring b. Then the first gripper 104 grabs the sleeve c and moves downward to tightly sleeve the bifurcations b1 of the crown spring b on the outer side wall of the tubular part a. At this time, the sleeve c operation at one end of the tubular part a is completed.

[0055] The working process of the second sleeve mechanism 8 is as follows: when the conveying line 2 transfers the insertion jig 21 with the tubular part a and the crown spring b inserted therein to the working station of the second sleeve mechanism 8, the first gripper 104 of the second sleeve mechanism 8 grabs the sleeve c at the grabbing position of the corresponding conveying track 101 above the tubular part a. Then the ejector pin moves downward, so that the outer side surface of the ejector pin spreads the bifurcations b1 of the crown spring b. Then the first gripper 104 grabs the sleeve c and moves downward to tightly sleeve the bifurcations b1 of the crown spring b on the outer side wall of the tubular part a. At this time, the sleeve c operation at the other end of the tubular part a is completed.

[0056] Further, an extension part is also arranged at the bottom of the spread part, and the diameter of the extension part decreases successively from top to bottom.

[0057] Among them, when the extension part of the expansion part can cause an inward bend at the bifurcation b1 of the crown spring b, it can ensure that the expansion part can extend into the crown spring b, so as to ensure that the expansion part can expand all the bifurcations b1 of the crown spring b.

[0058] Further, the conveying track 101 includes a conveying strip, a conveying groove 102 is opened on the conveying strip along the length direction of the conveying strip, and a receiving groove 103 is opened on the upper surface of one end of the conveying strip facing the conveying line 2 along the vertical direction of the conveying strip. The receiving groove 103 communicates with the conveying groove 102, and both ends of the receiving groove 103 extend out of the conveying strip to form a grasping position; the first gripper 104 is a flat gripper cylinder.

[0059] Among them, the grasping position is the receiving groove 103 extending out of both ends of the conveying strip, which can facilitate the flat gripper cylinder to directly grasp the tubular part a, the crown spring b and the sleeve c located in the conveying groove 102.

[0060] Further, the clamping device 112 includes a vertically arranged cylindrical insertion rod 1121, and a plurality of vertically arranged clamping strips 1122 are arranged on the outer side wall of the insertion rod 1121. The clamping strips 1122 protrude from the surface of the insertion rod 1121 and are uniformly arranged around the insertion rod 1121, and the number of the clamping strips 1122 is the same as the number of the insertion slots 213; the flipping mechanism 7 includes a mounting seat that is liftably arranged on the frame 1, and a second gripper 12 is arranged on the mounting seat. The second gripper 12 is horizontally rotatably arranged on the mounting seat.

[0061] Among them, the clamping method of the clamping device 112 for the bifurcation b1 of the crown spring b is as follows: First, the insertion rod 1121 moves down to be inserted into the crown spring b. At this time, since the position of the bifurcation b1 of the crown spring b is fixed, the clamping strips 1122 on the insertion rod 1121 will be embedded between two adjacent bifurcations b1. Then, by rotating the insertion rod 1121, the twisting of the bifurcation b1 of the crown spring b can be realized, and further the twisting of the crown spring b can be realized.

[0062] Among them, the second gripper 12 of the flipping mechanism 7 can be a cylinder gripper. After the second gripper 12 grabs the tubular part a, the tubular part a can be turned upside down by 180° through its horizontal flipping.

[0063] In addition, during the process of inserting the crown spring b into the clamping hole 211, it is not necessary to care whether the fork b1 of the crown spring b is inserted into the slot 213. Instead, the fork b1 of the crown spring b is inserted into the slot 213 through the torsion mechanism 5 to fix the crown spring b. For example, the part of the bottom of the clamping hole 211 located between two adjacent slots 213 is made into a boss shape to form a sliding part 214, and the cross-section of the boss-shaped part in the direction perpendicular to the radial direction of the clamping hole 211 is semicircular, that is, the surface of the boss-shaped part bends downward toward the slots 213 on both sides. At this time, when the torsion mechanism 5 moves downward toward the crown spring b to twist the crown spring b, after the torsion mechanism 5 abuts against the crown spring b, the horizontal component force generated by the pressure applied to the crown spring b will cause the fork b1 of the crown spring b abutted against the sliding part 214 to slide down along the surface of the sliding part 214 into the slot 213, so that the crown spring b is fixed in the clamping hole 211.

[0064] Furthermore, the blanking mechanism 9 includes a third gripper disposed on the frame 1 through a displacement mechanism.

[0065] After the crown spring socket is assembled, the crown spring socket can be moved from the assembly jig to a preset position through the third gripper to complete the blanking operation of the crown spring socket.

[0066] The above embodiments only illustrate several implementation manners of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
