The guide piece has a front limit position and a rear limit position in the left and right direction, namely the guide direction, due to the action of the limit spring 26 and the limit rod 23, the front extending stroke of the telescopic driving device 10 in the active compression joint device is larger than the front limit stroke of the guide piece, the rear retracting stroke of the telescopic driving device 10 in the active compression joint device is larger than the rear limit stroke of the guide piece, when the telescopic driving device 10 still extends forwards and retracts backwards, the guide piece is already at the limit position and cannot move, at the moment, the pressure head 30 is driven to swing by the driving arm 28 and the connecting rod 27 which are connected between the pressure head 30 and the guide piece, and the pressure head 30 correspondingly compresses and releases the flange 60 to be tested.
Operating personnel is using the utility model provides a when the withstand voltage unit test device of GIS comes flange, drive transmission shaft 11 rotation through the drive unit 70 of compriseing motor 71 and reduction gear 72 earlier, transmission shaft 11 sets up to can drive the lead screw protraction as flexible end in flexible drive arrangement 10 when corotation, stretches the action before this and moves right promptly. The drive shaft 11 rotates in reverse to drive the screw to retract, and then the retracting action moves to the left. When in butt joint, an operator drives the transmission shaft 11 to rotate forwards to drive the pressure head 30 and the connecting rod mechanism 20 to move forwards in a horizontal and direct movement mode, the guide piece gradually approaches the front limit position in the advancing process, after the stop nut 25 on the stop rod 23 is in stop fit with the sleeve 22, the stop rod 23 does not move any more, the forward stroke of the telescopic driving device 10 is greater than the forward limit stroke of the guide member, the ram 30 is driven to move forward continuously, at this time, the stop rod 23 generates a backward pulling force on the connecting rod 27, because the hinge point of the connecting rod 27 and the driving arm 28 is located on the side of the guide member far away from the pressure head 30, one end of the driving arm 28 is limited and swings outwards around the hinge point with the connecting rod 27, the driving arm 28 drives the pressure head 30 to move synchronously when acting, the pressure head 30 swings outwards around the hinge seat, and the bending head 31 on the pressure head 30 is far away from the base flange 50 at the moment, so that a butt joint space is provided for the butt joint of the base flange 50 and the flange 60 to be tested.
After an operator butts the base flange 50 and the flange 60 to be tested, the flange 60 to be tested needs to be pressed to the base flange 50 through the flange butting device, at the moment, the drive transmission shaft 11 is driven to rotate reversely, the telescopic driving device 10 retracts to drive the pressure head 30 in the expanded state to contract, at the moment, the limiting rod 23 releases the limiting state, and the reset spring 34 arranged between the pressure head 30 and the limiting seat 33 pulls the pressure head 30 to swing towards the base flange 50. In the process of moving backwards, the limiting spring 26 in the guide piece is pressed all the time until the limit spring reaches the parallel-loop state and cannot be compressed continuously, at this time, the movement of one end of the connecting rod 27 hinged at the front end of the guide piece is blocked, but because the backward movement stroke of the telescopic driving device 10 is larger than the backward limit stroke of the guide piece, the screw rod still retracts backwards, the driving arm 28 connected to the pressure head 30 can be subjected to the resistance of the connecting rod 27 for preventing the direct movement, because the hinge point of the driving arm 28 and the connecting rod 27 is located on one side of the guide piece far away from the pressure head 30, under the condition that one end of the connecting rod 27 cannot move directly, the pressure head 30 still has the movement trend of swinging towards the base flange 50, at this time, the connecting rod 27 swings towards the base flange 50 around the hinge point hinged with the guide piece.
In other embodiments, the motor can be directly arranged on the outer peripheral surface of the device base body, and a scheme that a bracket is arranged on the device base body to support the motor is not adopted; alternatively, the motor may be fixed to one of the crimping devices.
In other embodiments, the lead screw may be provided with a rotation stop pin, the cylinder may be provided with a rotation stop plane for stopping and matching with the rotation stop pin to limit the rotation of the lead screw, rather than being limited to a limiting seat formed by two baffles to limit the rotation,
in other embodiments, a driving wheel connected to a power source may be provided between adjacent crimping devices, and the driving wheel is connected to a driving wheel in each crimping device through a chain or a timing belt, so as to realize synchronous operation of each crimping device, without being limited to providing a master crimping device and a slave crimping device.
In other embodiments, the guide member may have other structures, for example, a track may be fixedly disposed, a slider hinged to the connecting rod is disposed on the track, the front end and the rear end of the slider in the guiding direction are connected to limit rods for limiting displacement of the slider, and the limit rods are correspondingly provided with limit protrusions capable of being in stop fit with the limit plates disposed on the track to limit the stroke of the slider, without being limited to the scheme of using the sleeve to be in plug-in fit with the sleeve.
In other embodiments, the limiting rod may be provided with a limiting pin, a limiting block, and other structures arranged perpendicular to the axial direction of the limiting rod, instead of the limiting spring.
In other embodiments, the actuating arm can adopt a style of calligraphy structure, and the actuating arm can be connected with the pressure head is perpendicular or the slant, but the pin joint of actuating arm and connecting rod need set up to be located the side direction of the tie point of actuating arm and pressure head, can make the connecting rod be close to the one end of pressure head and be higher than the one end of keeping away from the pressure head, also can make the connecting rod be close to the one end of pressure head and be less than the one end of keeping away from the pressure head to this guarantees that the pin joint of actuating arm and connecting rod is located the.
