Abstract
The invention relates to an automatic hydraulic positioning and clamping structure, in particular to the automatic hydraulic positioning and clamping structure used in the process of machining large cylindrical workpieces such as steel pipes and round steel to automatically position and clamp the ends of the workpieces and belongs to the technical field of mechanical equipment. The automatic hydraulic positioning and clamping structure comprises clamping claws, clamping claw arms, transmission screw rods, bearing seats, a claw disc seat, a drive motor, a drive gear and a driven gear. The drive motor is fixed to the rear end of the claw disc seat. The drive gear is arranged at the front end of an output shaft of the drive motor. The multiple clamping claw arms are arranged on the surface of the front end of the claw disc seat. Each clamping claw arm is internally provided with one transmission screw rod, and the bearing seats are arranged at the two ends of the transmission screw rods for supporting. One ends of the transmission screw rods stretch out from the clamping claw arms and are connected with the driven gear. The driven gear is connected with the drive gear in a meshing manner. The automatic hydraulic positioning and clamping structure can automatically position and clamp the ends of the large cylindrical workpieces such as the steel pipes and the round steel in the machining process, operation is convenient and reliable, cost is low, and harm, caused by improper operation, to people can be effectively avoided.
Description
Technical field
The present invention relates to the automatic positioning clamping of a kind of hydraulic pressure, specifically in the large cylindrical such as steel pipe, round steel workpiece process, can realize automatically locating clamping in its end, belong to mechanical equipment technical field.
Background technology
Before the present invention makes; in prior art; in the large cylindrical such as steel pipe, round steel workpiece process; clamping manually need be located usually in end; because workpiece is huge, artificial location clamping is wasted time and energy, and efficiency is low; and the defencive function lacked people, easily because misoperation causes the injury to people.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus provide a kind of hydraulic pressure automatic positioning clamping, can for the large cylindrical such as steel pipe, round steel workpiece end be tight from locating clip of starting building in process, easy to operate, reliable, cost is low, and can effectively avoid because misoperation causes injury to people.
According to technical scheme provided by the invention, the automatic positioning clamping of hydraulic pressure comprises claw, claw arm, drive lead screw, bearing block, pawl dish seat, drive motor, driving gear and driven gear, it is characterized in that: pawl dish base rear end fixed conveyor motor, the output shaft of drive motor stretches out from Zhao Panzuo center, and the front end of the output shaft of drive motor is provided with driving gear; Pawl dish seat front-end surface is provided with multiple claw arm, and multiple claw arm is uniformly distributed along the circumferencial direction of pawl dish seat; Be provided with a drive lead screw in each claw arm, drive lead screw two ends are provided with bearing block and support; One end of drive lead screw is stretched out and connects driven gear in claw arm, and driven gear and driving gear are connected with a joggle; Described drive lead screw is threaded connection claw, when drive lead screw rotates, drives claw along drive lead screw axially-movable.
Further, claw arm is three.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, can for the large cylindrical such as steel pipe, round steel workpiece end is tight from locating clip of starting building in process, and easy to operate, reliable, cost is low, and can effectively avoid because misoperation causes injury to people.

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Fig. 1 ~ 3, the present invention mainly comprises claw 1, claw arm 2, drive lead screw 3, bearing block 4, pawl dish seat 5, drive motor 6, driving gear 7 and driven gear 8.
Pawl dish seat 5 rear end fixed conveyor motor 6, the output shaft of drive motor 6 stretches out from pawl dish seat 5 center, and the front end of the output shaft of drive motor 6 is provided with driving gear 7.
Pawl dish seat 5 front-end surface is provided with multiple claw arm 2, and multiple claw arm 2 is uniformly distributed along the circumferencial direction of pawl dish seat 5.In embodiment as shown in Figure 2, described claw arm 2 is three.
Be provided with a drive lead screw 3 in each claw arm 2, drive lead screw 3 two ends are provided with bearing block 4 and support.One end of drive lead screw 3 is stretched out and connects driven gear 8 in claw arm 2, and driven gear 8 and driving gear 7 are connected with a joggle.
Described drive lead screw 3 is threaded connection claw 1, when drive lead screw 3 rotates, drives claw 1 along drive lead screw 3 axially-movable.
The operation principle of invention is: during work, drive motor 6 provides power, and drive motor 6 drives driving gear 7, driving gear 7 engages with multiple driven gear 8 simultaneously, drive multiple driven gear 8 synchronous axial system, driven gear 8 connection for transmission screw mandrel 3, drive drive lead screw 3 to rotate around bearing block 4.Drive lead screw 3 and claw 1 are threaded connection, and claw 1 and claw arm 2 are slidably connected, and claw 1 can be driven to move axially along drive lead screw 3 when ensureing that drive lead screw 3 rotates.The same of multiple claw 1 enters to move back together, and then realizes the clamping of cylindrical workpiece location.
