Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, an automatic screwing assembly mechanism for screw shielding position mainly includes a screwdriver mechanism, a screw clamping mechanism and a screwdriver mechanism, wherein the screwdriver mechanism is used for receiving a bolt 12 and is arranged in a lifting manner, the screw clamping mechanism is used for clamping the bolt 12 and is arranged in a movable manner, the batch knife mechanism comprises a batch knife which is obliquely arranged, one end of the batch knife is driven to move by the batch knife moving mechanism, and the other end is provided with a screwing part, the screwdriver moving mechanism can drive the screwdriver to move to a position right above the screw position of the product, and the screwdriver is provided with an inclined angle, so that the screwdriver can avoid the raised part of the product screw position to carry out screwing work, and then the screwing part screws the bolt 12 to realize screwing fixation, therefore, the situation that automatic screwing cannot be realized and only manual screwing is required when a bulge is arranged near the screw position of some products to shield the screwdriver position for screwing the screw is avoided.
In this embodiment, this kind of automatic equipment mechanism of twisting soon still includes the guide rail 3 of fixed setting, criticizes mouth mechanism fixed setting in one side of rail 3, and screw fixture and guide rail 3 sliding connection, wherein, screw fixture includes claw clamp cylinder 5 and is fixed in the screw clamp 6 of the 5 output ends of claw clamp cylinder, and sliding connection has claw clamp cylinder block 4 on the guide rail 3, and claw clamp cylinder 5 and claw clamp cylinder block 4 fixed connection. In order to enable the screwing part to screw the bolt 12 into the product, the claw clamp cylinder 5 can drive the screw clamp 6 to open and return, a position detector is arranged at the end part of the screw clamp 6 and drives the claw clamp cylinder 5 to move through outputting a signal to a control system, one end of the guide rail 3 is fixedly connected with a pushing cylinder seat 2, a push-pull cylinder 7 which is the same as the extension direction of the guide rail 3 is fixedly arranged on the pushing cylinder seat 2, the output end of the push-pull cylinder 7 is connected with the claw clamp cylinder seat 4, the claw clamp cylinder seat 4 can be driven to move along the extension direction of the guide rail 3 through the push-pull action of the push-pull cylinder 7, in addition, support plates 1 are fixedly connected to the two sides of the pushing cylinder seat 2, and the support plates 1 are fixedly attached.
In this embodiment, the batch nozzle mechanism includes a lifting cylinder 9 fixed on one side of the guide rail 3 through a lifting cylinder seat 8, an output end of the lifting cylinder 9 is fixedly connected with a batch nozzle fixing plate 10, and one end of the batch nozzle fixing plate 10 far away from the lifting cylinder 9 is fixedly connected with a batch nozzle 11, in order to enable the screw clamp 6 to clamp the screw rod of the bolt 12 and then the batch nozzle 11 can be separated from the bolt 12, the front end of the batch nozzle 11 is provided with an elastic clamping portion, for example, the elastic clamping portion can be set into two clamps with springs, the two clamps are arranged on the left and right, and a hole is formed in the middle of the clamping ends of the two clamps, wherein the size of the hole is slightly larger than that of the screw rod and smaller than that of the bolt 12, because the nut head of the bolt 12 is larger than that of the screw rod, the two clamps with springs at the front end of the batch nozzle 11 can just, so that the screw clamp 6 clamps the exposed portion of the shank of the bolt 12 on the product. In the present embodiment, the gripper cylinder 5 is of type HFZ16-S and the lift cylinder 9 is of type HLQ8-20-S, both of which are available in the prior art.
The principle of the automatic screwing and assembling mechanism for the screw blocking position is as follows:
the bolt 12 is automatically blown into the batch nozzle 11 through a conveying pipe by a feeder, and the front end of the batch nozzle 11 is clamped by a left clamp and a right clamp with springs, so that the bolt 12 on a product automatically blown into the batch nozzle 11 through the conveying pipe by the feeder is clamped. Because the holes of the two clips with the springs at the front end of the screwdriver nozzle 11 just enable the screw rod part of the bolt 12 on the product to be exposed, and the nut head part of the bolt 12 on the product is larger than the screw rod, the two clips with the springs at the front end of the screwdriver nozzle 11 just can clamp the nut head part of the bolt 12 on the product, so that the nut head part cannot fall out, and the exposed part of the screw rod of the bolt 12 on the product can be clamped by the screw clamp 6.
At this time, the claw clamp air cylinder 5HFZ16-S drives the screw clamp 6 to clamp the exposed part of the screw rod of the bolt 12, then the lifting air cylinder 9HLQ8-20-S is lifted to drive the batch nozzle fixing plate 10 and the batch nozzle 11 to lift, and because the left and right clips at the front end of the batch nozzle 11 clamp the bolt 12 on the product by the spring clamp, the two clips cannot be clamped, so that when the lifting air cylinder 9HLQ8-20-S is lifted to drive the batch nozzle fixing plate 10 and the batch nozzle 11 to lift, the left and right clips at the front end of the batch nozzle 11 are in the compression and retreat process of the spring, and the bolt 12 is separated from the batch nozzle 11.
At the moment, the push-pull air cylinder 7MIC-16-75-S waits for a command of pushing the bolt 12 on the product sent by the host control system, and after the command is received, the push-pull air cylinder 7MIC-16-75-S pushes the whole jaw clamp air cylinder 5HFZ16-S and the bolt 12 clamped by the screw clamp 6 to be conveyed to the position where the product needs to be screwed.
Because the position of the screwdriver for screwing the screw is shielded by the bulge near the screw position of the product, the screwdriver is designed to have a moving mechanism and has an inclined angle. When the batch knife moves down to the position near the bulge of the product screw position, the batch knife moving mechanism drives the batch knife to move right above the product screw position so as to avoid colliding with the bulge of the product screw position. Because the screwdriver is inclined, the screwdriver can avoid the raised part of the screw position of the product to carry out screwing work. At the moment, the screwdriver descends while rotating until the nut head approaches the screw clamp 6 after the bolt 12 is screwed into the product, the position detector sends a signal to enable the jaw clamp air cylinder 5HFZ16-S to drive the screw clamp 6 to open and retract, then the lifting air cylinder 9HLQ8-20-S descends to drive the batch nozzle fixing plate 10 and the batch nozzle 11 to descend and reset, and then the feeding system blows the bolt 12 into the batch nozzle 11 again for the next cycle of work.
And meanwhile, when the screwing work is finished, the screwdriver is circulated once, namely a process, and is repeated in cycles, so that the screwdriver continuously and automatically supplies the bolts 12 for the main body assembling equipment and finishes the screwing assembling work of the bolts.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
