Examples:
as shown in fig. 1-6, the automatic assembly device for the finger-shaped contact of the low-voltage air breaker comprises a plurality of tool positions arranged around a rotary workbench 6, wherein the tool positions are arranged along the circumferential direction of the rotary workbench 6. The rotary workbench 6 is provided with a fixture matched with each fixture, and the fixture at least comprises three clamping positions side by side. The clamping position in the middle is a first position 61 for realizing the rotation of the contact structure, and two sides of the first position 61 are second positions 62 for realizing the lamination of the contacts and the installation of the supporting sheets. The two second locations 62 are identical in construction and are referred to as first locations 61. Because the design is made according to the structure of the low-voltage air circuit breaker, the arrangement of the finger-shaped contacts is symmetrical. The assembly design is therefore also dependent on its constructional features. The plurality of contacts are stacked in a second position 62 and maintained in stacked alignment by the second position 62. And the first position 61 is used to secure the two "half" assemblies together.
According to the switching procedure of the low-voltage air circuit breaker, the corresponding mechanism is arranged on the tooling position and comprises: a first mechanism 1 for realizing the lamination placement of a plurality of contacts, a second mechanism 2 for realizing the placement of supporting sheets between the contacts, a third mechanism 3 for realizing the grabbing and steering of the contacts, a fourth mechanism 4 for realizing the installation of an external retainer of the contacts, and a fifth mechanism 5 for realizing the joggling of the contacts and the retainer. Wherein, the first mechanism to the fifth mechanism are used for assembly, and the sixth mechanism mainly realizes parameter detection of the finished product.
Specifically, the first mechanism 1 includes: the first vibration groove 11 for linearly conveying the contacts, and the first clamping assembly for clamping the plurality of contacts from the first vibration groove 11 to the corresponding second position 62. One end of the first vibration groove 11 is connected to the first vibration plate 12, and the other end thereof is led to the rotary table 6. The first vibration plate 12 and the first vibration groove 11 adopt the existing vibration feeding structure, and the contact piece is conveyed along the linear direction through vibration of the vibrator. The first clamping assembly comprises the same feeding direction as the first vibrating trough 11: a first transverse rail 13, a first transverse cylinder 14; a first vertical cylinder 15 is fitted on the first transverse rail 13, and the first transverse cylinder 14 pushes the first vertical cylinder 15 to slide on the first transverse rail 13. The first vertical cylinder 15 vertically pushes and pulls the first pneumatic clamping jaw 16, and the two first clamping jaws 6 clamp the contact from the first vibration groove 11 and put the contact into the corresponding fixture on the rotary workbench. As shown in fig. 2: the second positions 62 on the fixture are provided with two, so that two groups of vibration feeding assemblies can be arranged corresponding to the positions of the two groups of vibration feeding assemblies to realize simultaneous feeding so as to increase the working efficiency.
The second mechanism 2 includes: the second vibration groove 21 of the linear conveying support piece clamps the support piece from the second vibration groove 21 to the second clamping assembly on the contact in the corresponding second position 62. The second mechanism 2 is a support piece for mounting between contacts, the support piece including a plurality of teeth, one for each contact, which need to be placed on the side end face of the contact piece for supporting. Therefore, one end of the second vibration groove 21 is connected to the second vibration plate 22, and the other end thereof is also led to the rotary table 6. Similar to the first mechanism 1, the specific structures of the second vibration groove 21 and the second vibration plate 22 are not described in detail. As shown in fig. 3, the second clamping assembly comprises a second transverse rail 23 with the same feeding direction as the second vibration groove 21, the second transverse rail 23 is matched with a second transverse cylinder 24 for pushing and pulling, and the second transverse rail 23 is matched with a second vertical cylinder 25. The second vertical cylinder 25 pushes and pulls a first rotary cylinder 26, and the first rotary cylinder 26 drives a negative pressure suction head for sucking the support piece on the second vibration tank.
The third mechanism 3 includes: and a third clamping assembly for simultaneously clamping the workpiece in the two second positions 63 and for placing the workpiece in the first position 61 after rotation. As shown in fig. 4, the third clamping assembly mainly comprises two pneumatic second clamping jaws 31 corresponding to the second position 62, the second clamping jaws 31 not only comprising clamping forces enabling simultaneous clamping of multiple contacts, but also providing a pneumatic pushing force for holding the support plate. The clamping force is realized by a transverse air cylinder, and the thrust is realized by a vertical air cylinder. The two second clamping jaws 31 are each connected to a second rotating cylinder 32, the second rotating cylinders 32 can realize their synchronous turning, and the two second rotating cylinders 32 send synchronous opposite rotation, so that the two "half" contact assemblies are rotated to the vertical direction. At the same time, the second rotary cylinder 32 is fitted over a vertical linear module 33, so that the second jaw 31 can load two "half" pieces into the first position 61 as it descends vertically.
The fourth mechanism 4 includes: a third vibration groove 41 for linearly conveying the retainer, and a fourth clamping assembly for clamping the retainer from the third vibration groove 41 to the workpiece in the first position 61. The third vibration groove 41 is connected with a third vibration disk for continuously conveying the retainer, which is similar to the vibration structures in the first mechanism and the second mechanism and belongs to common vibration feeding structures. As shown in fig. 5, the fourth clamping assembly is similar to the first clamping assembly and includes a third transverse rail 43, a third transverse cylinder 44, a third vertical cylinder 45, and a third jaw 46. Unlike the first mechanism 1, the fourth mechanism 4 is to bring a cage to the first position 61, which is nested outside the contact assembly of the two "halves" forming an outer frame. At this time, the semi-finished product does not have a fixed structure, and the retainer and the inner contact assembly are connected by the tenons and the two contact assemblies are kept tensioned in the retainer, so that the structural stability of the product can be ensured.
The fifth mechanism 5 includes: a fourth vibratory groove 51 for linearly transporting the tenon, and a fifth clamping assembly for clamping the tenon from the fourth vibratory groove 51 and into the work piece in the first position 61. Similar to the vibrating structure in the first mechanism 1, the second mechanism 2, and the fourth mechanism 4, the fourth vibrating slot 51 is used in combination with the fourth vibrating disk for continuously conveying the tenons. As shown in fig. 6, the fifth clamping assembly includes a fourth vibration groove 51 horizontally disposed and perpendicular to: a fourth transverse cylinder 53, a fourth transverse rail 54. The fourth transverse cylinder 53 pushes and pulls a fourth vertical cylinder 55 fitted on the fourth transverse rail 54, and the fourth vertical cylinder 55 pushes and pulls a negative pressure suction head for sucking the tenon. A bottom plate 56 is arranged below the fourth transverse rail head 54, and a chute and a fifth transverse cylinder 57 which have the same feeding direction as the fourth vibration chute 51 are arranged on the bottom plate 56. The suction head is arranged in a chute, the chute faces the workpiece at the first position 61, a tenon hole is formed in the workpiece, and the fifth transverse air cylinder 57 pushes the tenon forwards along the chute to enable the tenon to be inserted into the workpiece. The bottom plate 56 is simultaneously arranged on a linear module which has the same direction as the fifth transverse cylinder 57, and can perform a feeding effect to ensure that the sliding chute is aligned with the mortise.
