Description

Rotary turning plate boring machine machining clamping mechanism

Technical Field

The invention belongs to the technical field of machining, and particularly relates to a machining clamping mechanism of a rotary turning plate boring machine.

Background

Along with the development of production technology, the requirements for industrial production of engineering machinery processing are higher and higher, and especially for boring processing of engineering machinery parts and the like, the requirements for boring precision are higher and higher.

Chinese utility model patent with publication number CN201455704U discloses a boring machine and boring machine anchor clamps, including the bottom plate that the level set up, fixed mounting is the vertical support frame on the bottom plate, and the splint that the level set up are connected to the support frame top, installs the adjusting part on the bottom plate, and the common centre gripping work piece of adjusting part and splint.

However, the boring machine fixture disclosed above is only suitable for clamping a workpiece with a regular shape, and for a irregularly-shaped workpiece with a irregular shape, it is difficult to stably limit the irregularly-shaped workpiece on the bottom plate, so that when boring a irregularly-shaped workpiece, the irregularly-shaped workpiece is easily rotated, and further the processing difficulty is increased, the boring precision is reduced, and the product quality is reduced.

Disclosure of Invention

The invention aims to provide a machining clamping mechanism of a rotary turning plate boring machine, which can solve the problem that machining precision is influenced because irregular special-shaped pieces are difficult to clamp firmly when the irregular special-shaped pieces are machined in the field of machining.

The technical purpose of the invention is realized by the following technical scheme:

the utility model provides a rotatory board boring machine processing clamping machine constructs that turns over, includes the workstation, a revolving stage top surface is located to the workstation bottom, the activity of workstation top is equipped with the opening orientation the V template of workstation top surface, and is used for supporting the supporting component of V template.

Further, the supporting component includes the backup pad of two relative settings, the backup pad level sets up, and is located two between the backup pad are the X type and rotate the bracing piece of connecting, two the terminal surface that the backup pad is relative is equipped with a bull stick respectively, bracing piece one end and one of them bull stick sliding connection, and follow the bull stick axial slides, the other end with bull stick threaded connection, and two the screw thread opposite direction of bracing piece.

Furthermore, the top end of the V-shaped plate is arranged on a cross rod, and the cross rod is erected above the workbench through a supporting component.

Furthermore, the top ends of the two support arms of the V-shaped plate are respectively connected with the cross rod in a rotating manner.

Furthermore, a control rod for controlling the rotation of the support arm is arranged between the support rod and the support arm of the V-shaped plate.

Furthermore, one end of the control rod is fixedly connected with the support rod, the other end of the control rod slides and penetrates through the thickness of the V-shaped plate support arm, and an arc-shaped limiting hole matched with the control rod is formed in the V-shaped plate support arm; two the bracing piece relative rotation drives two the control lever removes, drives V template support arm relative rotation presss from both sides the work piece tightly, just V template support arm one end all the time with the workstation laminating.

Furthermore, two slide between the backup pad and run through and be equipped with the guide post.

Furthermore, a tooth-shaped structure is horizontally arranged at a half circumferential distance of the side wall of the rotating platform, the rotating platform is arranged in a rectangular frame, racks matched with the tooth-shaped structure of the rotating platform are arranged on two inner side walls of the frame, and the frame is driven by a cylinder to move in a reciprocating manner along the length direction of the racks.

Compared with the prior art, the invention has the beneficial effects that:

1. when the workpiece is machined, the workpiece can be clamped in a clamping cavity between the V-shaped plate and the end face of the workbench, and then the workpiece is machined by using a boring hole or other equipment.

Compared with the use of the corner cylinder, the rotation of the workbench can be realized by both the two schemes, but the corner cylinder is high in price in terms of cost, and cost is not saved during industrial production.

3. The supporting component is set to be of an X-shaped structure, so that when the height of the supporting component needs to be adjusted, only the rotating rod of the manual driving and supporting rod threaded connection of an operator needs to rotate, the two supporting rods can be driven to rotate relatively, the height of the clamping mechanism can be adjusted, and a workpiece can be better clamped and fixed.

Two support arms of V-shaped plate rotate with the horizontal pole and be connected, and set up the control lever between the support arm of bracing piece and V-shaped plate, like this, when reciprocating through supporting component drive V-shaped plate, can drive two support arms relative rotations of V-shaped plate simultaneously to can the centre gripping work piece of different size of a dimension.

5. According to the invention, the arc-shaped limiting hole matched with the control rod is formed in the support arm of the V-shaped plate through the thickness of the support arm, and the control rod is inserted in the limiting hole in a sliding manner, so that the control rod can be ensured to smoothly drive the support arm of the V-shaped plate to rotate along with the movement of the support rod, and simultaneously, the lower end surfaces of the two support arms are ensured to be always attached to the top surface of the workbench, so that a gap is prevented from being left between the support arm of the V-shaped plate and the workbench, and the clamping.

6. The guide post is arranged between the two support plates in a sliding mode, so that the whole support assembly can be stably placed on the workbench, the V-shaped plate can be supported, and deflection cannot occur.
