The punching machine mainly comprises a workbench for placing workpieces to be processed and a punching machine head for punching, in the punching process, the punching is accurate for ensuring the punching, the fixing and clamping of the workpieces are particularly important, the workbench of the existing punching machine is lack of a device capable of stably clamping the workpieces, and the processing precision is influenced to a certain extent.
Disclosure of Invention
In order to overcome the defect that the existing punching machine is lack of a workpiece clamping device, the invention provides a workpiece clamping mechanism of a punching machine, which solves the problem by symmetrically arranging pressure plates which are rotatably adjusted at two sides of a workbench.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a punching machine work piece clamping machine constructs, sets up on the workstation, sets up the clamping unit in the workstation both sides including the symmetry, and the clamping unit mainly comprises vaulting pole, spring, clamp plate and compresses tightly the hand wheel, clamp plate and spring cover in proper order and establishes on the vaulting pole, and the clamp plate vertically adjusts from top to bottom along the vaulting pole under the spring action, and clamp plate one side is provided with the puller pin that is used for compressing tightly the work piece, and the clamp plate opposite side is provided with the supporting pin that is used for balanced.
Furthermore, a discharge chute is formed in the middle of the workbench, and a sliding seat embedded in the discharge chute is arranged at the bottom of the support rod.
Furthermore, the top end of the support rod is provided with an external thread section matched with the pressing hand wheel, and the bottom of the support rod is provided with an external thread section matched with the sliding seat.
Furthermore, one end of the supporting pin extends into the discharging groove, and the other end of the supporting pin props against the lower surface of the pressing plate.
Furthermore, one end of the puller pin is inserted into the pressing plate, and the other end of the puller pin props against the upper surface of the workpiece.
Furthermore, the pressing hand wheel is composed of a movable seat sleeved on the support rod and handles uniformly distributed on the periphery of the movable seat.
The clamping device has the advantages that the workpiece to be machined is stably clamped by the two groups of pressing plate clamping mechanisms symmetrically arranged on the workbench, so that the workpiece is prevented from displacing in the stamping process; the workpiece is abutted through the jacking pin, and the pressing plate is guaranteed to be clamped stably and horizontally through the supporting pin, so that the stamping efficiency is improved.
Drawings
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic structural view of the present invention.
In the figure, 1, a workbench, 2, a support rod, 3, a spring, 4, a pressure plate, 5, a pressing hand wheel, 6, a jacking pin, 7, a supporting pin, 8, a sliding seat and 9 are arranged on a workpiece.
Detailed Description
As shown in fig. 1, which is a schematic structural diagram of the present invention, a workpiece clamping mechanism of a punching machine is arranged on a workbench 1, and comprises clamping units symmetrically arranged on two sides of the workbench 1, wherein each clamping unit mainly comprises a stay bar 2, a spring 3, a pressing plate 4 and a pressing hand wheel 5, the pressing plate 4 and the spring 3 are sequentially sleeved on the stay bar 2, the pressing plate 4 is vertically adjusted along the stay bar 2 under the action of the spring 3, one side of the pressing plate 4 is provided with a puller pin 6 for pressing a workpiece 9, and the other side of the pressing plate 4 is provided with a support pin 7 for balanced support.
During the use, will treat that the processing work piece steadily places the upper surface at workstation 1, then adjust the interval of both sides clamping unit through slide 8 for the tight round pin 6 in top of clamping unit one side can contact the work piece upper surface, for guaranteeing the clamping balance, set up supporting pin 7 at the opposite side of clamp plate 4, the specification of supporting pin 7 and tight round pin 6 in top chooses for use according to the in-service use demand, adjust the back, manual rotation compresses tightly hand wheel 5, locks clamp plate 4, thereby accomplish the clamping to the work piece.
The middle part of the working table 1 is provided with a discharge chute, and the bottom of the stay bar 2 is provided with a slide seat 8 embedded in the discharge chute. The discharge chute is transversely opened, and the slide seat 8 is in sliding connection in the discharge chute.
The top end of the support rod 2 is provided with an external thread section matched with the pressing hand wheel 5, and the bottom of the support rod 2 is provided with an external thread section matched with the sliding seat 8. Threaded connection is stable and reliable, and it is also more convenient to dismantle, and the horizontal position of clamp plate 4 is adjusted to slide 8, and the vertical position of clamp plate 4 is carried out spacing locking to compressing tightly hand wheel 5.
One end of the supporting pin 7 extends into the discharging chute, and the other end of the supporting pin 7 is propped against the lower surface of the pressure plate 4. One end of the puller pin 6 is inserted into the pressing plate 4, and the other end of the puller pin 5 is propped against the upper surface of the workpiece 9.
