Background
In order to improve the assembly efficiency of products, the automatic screw locking machine is widely applied to production and processing, and the automatic operation of screw feeding and locking can be realized. However, for some assembly parts with special assembly requirements, if a gasket with a direction requirement is required to be installed below the screw, for example, when the gasket is square, the existing automatic screw locking machine cannot be applied, because: for the operation of cooperation auto-screwdriving machine, the installation position and the screw hole of all square gaskets on the assembly part all need be unified angle setting, and current assembly part can not satisfy this requirement, can only lock through the mode of artifical handheld electric screwdriver and attach, and production efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes among the prior art when the square gasket of screw below installation, can only lock through the mode of artifical handheld electric screwdriver and attach, the shortcoming that production efficiency is low provides a rotation type centre gripping fixing device.
The utility model discloses the technical scheme who realizes that the purpose adopts is: a rotary clamping fixture for clamping and securing an assembly during a screw locking process, the rotary clamping fixture comprising: the clamping part comprises an assembly part fixing disc and clamping jaws, and a group of clamping jaws are arranged on the edge of the assembly part fixing disc and extend upwards; the rotation control part comprises: the output shaft of the motor is connected with the driving wheel of the transmission mechanism, the driven wheel of the transmission mechanism is coaxially connected with the assembly part fixing disc, and the rotation control part is fixedly connected with the rack; the position detection component comprises an inductor and an induction sheet, the inductor is fixedly connected with the rack, and the induction sheet is fixedly connected with a driven wheel of the transmission mechanism.
Furthermore, the motor is a servo motor, and the transmission mechanism is a belt transmission mechanism.
Furthermore, the clamping jaw position sensor is further included and fixedly connected with the rack.
The utility model has the advantages that: the utility model discloses a rotation control part drives the assembly part fixed disk and rotates, and the rotation is adjusted by the assembly part of centre gripping, effectual installation position to each square gasket and the angle of putting of screw hole, makes it accord with the operation requirement of auto-screwdriving machine, through the cooperation operation with auto-screwdriving machine, realizes the full automatic locking of screw of band-pass direction gasket, has improved production efficiency.
The present invention will be further described with reference to the accompanying drawings and the detailed description.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a view along a of fig. 1.
Fig. 3 is a view in the direction B of fig. 1.
In the attached drawing, 1 is a frame, 2 is an assembly part fixing disc, 3 is a clamping jaw, 4 is a motor, 5 is a transmission mechanism, 5-1 is a driven wheel, 6 is an inductor, 7 is an induction sheet, 8 is a clamping jaw position inductor, and 9 is an assembly part.
Detailed Description
As shown in the drawings, the rotary clamping and fixing device of the embodiment is used for clamping and fixing the assembly part 9 in the screw locking process. The rotary clamping fixture includes: a frame 1, a clamping component, a rotation control component and a position detection component of the clamping component.
The clamping part comprises a fitting piece fixing disc 2 and a clamping claw 3. A set of claws 3 is arranged at the edge of the fitting holding pan 2 and extends upwards. The claws 3 can rotate relative to the disc surface of the assembly part fixing disc 2 and are used for clamping and fixing the assembly parts 9 placed on the assembly part fixing disc 2. The preferred still include jack catch position inductor 8 of this embodiment, jack catch position inductor 8 and frame 1 fixed connection, when jack catch position inductor 8 senses jack catch 3 and is in the upwards extension state, assembly part 9 is fixed by jack catch 3, assembly part fixed disk 2 direction is rotatable.
The rotation control part comprises: a motor 4 and a transmission 5. An output shaft of the motor 4 is connected with a driving wheel of the transmission mechanism 5, and a driven wheel 5-1 of the transmission mechanism 5 is coaxially connected with the assembly part fixing disc 2. In the present embodiment, the motor 4 is preferably a servo motor, and the transmission mechanism 5 is preferably a belt transmission mechanism. The power is transmitted to the assembly part fixing disc 2 through the matching of the servo motor, the synchronizing wheel and the synchronous belt, the transmission precision and efficiency are higher, the uncertainty caused by open-loop control of the stepping motor can be overcome, the problems that the position of the assembly part fixing disc 2 is changed and the repeated positioning of screw holes is inaccurate due to the impact generated in the screw locking process are effectively avoided. The rotation control component is arranged on the frame 1 and is fixedly connected with the frame 1.
The position detection component comprises a sensor 6 and a sensing piece 7. The inductor 6 is fixedly connected with the frame 1, and the induction sheet 7 is fixedly connected with the driven wheel 5-1 of the transmission mechanism 5.
In actual use, the position of the sensing piece 7 is firstly sensed through the sensor 6, the initial position of the assembly fixing disc 2 is determined, namely the locking position of the first screw, after the first screw is locked, the motor 4 is driven by a program to rotate by a corresponding angle, the motor 4 transmits power to the assembly part fixing disc 2 through the transmission mechanism 5, in the embodiment, the servo motor drives the driving synchronous wheel to rotate, the driving synchronous wheel drives the driven synchronous wheel to rotate through the synchronous belt, the driven synchronous wheel drives the assembly part fixing disc 2 to rotate to a specified angle through the transmission shaft, i.e. the locking position of the second screw, and so on, until the screws on the assembly member 9 are all locked, in the whole process, when the mounting positions and the threaded holes of all the square gaskets on the assembly part 9 are positioned at the assembly position, the same angle is always kept, and the operation of the automatic screw locking machine is facilitated.
