Description

The inclined surface sliding jig described in the present invention is used in various mechanical equipment such as a machining center, a dragon gate machining center, a milling machine, a dragon gate milling machine, a boring machine, a dragon gate boring machine, a vertical lathe, and a drilling machine. Design jigs that apply force from below a predetermined angle (eg 40 °) to improve boring machines, side clamps and other similar jigs used in existing machinery.

The inclined surface sliding jig described in the present invention has a predetermined angle (predetermined angle) used in various mechanical equipment such as a machining center, a dragon gate machining center, a milling machine, a dragon gate milling machine, a dragon gate boring machine, a vertical lathe, and a drilling machine. For example, a jig that applies force from the lower side (40 °) is designed to supplement the technical defects of the upper and lower sandwiches, side clamps and other similar jigs used in existing machinery and equipment.

1 Upper and lower sheet metal, side clamps and other similar jigs used in existing machinery are complicated and inconvenient to operate in actual processing work, and the upper and lower sandwich plate method adopts the leverage balance principle. , The processed product is fixed using spacers of different thickness. Resonance during machining tends to cause lateral loosening and shifting of the machined product, which affects the accuracy and tolerance of the machined product. Similarly, even with the side clamp method, when the processed product is fixed, vertical loosening and shifting are likely to occur, which affects the accuracy and tolerance of the processed product.

2 When the upper and lower sandwich plates, side clamps and other similar jigs used in existing machinery and equipment are tightened vertically and horizontally, the fixing of the processed product is strengthened vertically and horizontally in all directions. There is a need. It takes time and there is a decrease in manufacturing efficiency.

3 The upper and lower sandwich plates, side clamps, and other similar jigs used in existing machinery and equipment fix the surface of the product processed by the normal force clamp during processing, so the fixed surface of the processed product is fixed. fall into disrepair. In order to fundamentally compensate for such defects, if the work piece is fixed by pushing diagonally from the side so that the work piece is not damaged or deformed, the angle control increases, so the clamping force of the work piece is controlled. By adjusting, the surface of the processed product is not damaged, and the defective product rate is fundamentally reduced.

In addition, as an example of a clamp tool used in an existing machine tool, Patent Document 1 proposes a continuously variable clamp tool used for fixing a material to be processed to a processing table of a machine tool.

It is necessary to consider designing a new inclined surface sliding jig to solve the problems existing in the existing technology described above and to solve the problems existing in the existing technology.

Regarding the existence of problems in the above-mentioned prior art, an object of the present invention is to study and design a new inclined surface sliding jig in order to solve the following problems existing in the prior art.

1 Simply fixing the processed product from top to bottom may cause problems such as lateral loosening and shifting. During processing, simply fixing to the side clamps may cause problems such as vertical loosening and shifting.

2 The discipline for fixing the processed product is not constant, and the work process is complicated, time-consuming, and production efficiency is low.

3 When fixing from top to bottom or from the side, the processed product is hardened straight, the surface of the processed product is easily damaged, and the incidence of defective products is high.

The technical solution measures of the present invention are realized as follows.

The inclined surface slide type jig of the present invention includes a work table of a mechanical device, an upper clamp block, an inclined surface of the upper clamp block, an upper plane of the upper clamp block, an elliptical hole at an intermediate position of the upper plane of the upper clamp block, and an upper clamp. It is characterized by including a tip of a block, a lower clamp block, an inclined surface of the lower clamp block, a screw hole A of the lower clamp block, a screw hole B of the lower clamp block, a screw hole C of the lower clamp block, and a bolt.

The independent clamp block of each set of the present invention is mainly composed of two parts, an upper clamp block and a lower clamp block, and the upper clamp block has an inclined surface of a predetermined angle (for example, 40 °) and is lower. The clamp block also has an inclined surface of a predetermined angle (for example, 40 °) that matches the inclined surface of the upper clamp block, and the bolt passes through an elliptical hole at an intermediate position on the upper plane of the upper clamp block and of the lower clamp block. Fixed to the screw hole C, the size of the bolt cap is larger than the elliptical hole at the intermediate position of the upper clamp block, and the upper clamp block and the lower clamp block are fixed with bolts to become a set clamp block.

There is an elliptical hole in the middle of the upper plane of each set independent clamp block of the present invention, which is used by locking when sliding and necessary fixing of the upper clamp block. The upper plane of the upper clamp block is parallel to the workbench of the mechanical equipment.

The tip of each set independent clamp block of the present invention becomes a flat surface, and the flat surface is attached to the processed product in order to fix the processed product, and the tip of the upper clamp block exerts force on the processed product.

The lower clamp of each set independent clamp block of the present invention has three screw holes. These are a screw hole A, a screw hole B, and a screw hole C. In the screw hole A and the screw hole B, the lower clamp block is fixed to the workbench of the mechanical device. The bolt passes through an elliptical hole at an intermediate position on the upper plane of the upper clamp block and is fixed to the screw hole C of the lower clamp block.

The upper clamp block and the lower clamp block of the present invention are in contact with the work table surface of the mechanical device at a predetermined angle (for example, 40 °). This 40 ° angle became the optimum angle of the present invention, and all tests showed that 40 ° was the optimum angle in terms of angle, and the tightening force was the best. In addition, other angles are also included in the claims according to the design of the present invention, for example, the range of 20 ° to 60 ° is preferable, the range of 30 ° to 50 ° is more preferable, and the range of 35 ° to 45 ° is further preferable.

When using the present invention, the procedure is as follows.
1 First, the user selects some necessary clamp blocks according to the form and structure of the actual processed product.

2 Using the inclined surface sliding jig of the present invention, first fix the processed product at the corresponding position on the workbench of the mechanical device, and pass through the screw hole A and screw hole B of the lower clamp block depending on the position of the processed product. , The lower clamp block of the first set of clamp blocks of several independent clamp blocks is fixed to the workbench of the mechanical equipment. There is an elliptical hole in the middle of the upper plane of each independent clamp block, and the upper plane of the upper clamp block is parallel to the workbench of the mechanical device.

The contact surface between the upper clamp block and the lower clamp block is at an angle of 40 ° with respect to the workbench of the mechanical device. The bolts pass through an elliptical hole in the mid-plane position of the upper clamp block and are fitted into the screw holes C of the lower clamp block, and the upper clamp block of each independent clamp block is at an angle of 40 ° to the workbench of the mechanical device. After sliding from the inclined surface side and the tip of the upper clamp block pushes the processed product, the bolt fitted in the screw hole C is turned.

The bolt of the screw hole C is in the elliptical hole in the middle position of the upper plane of the upper clamp block, and the size of the bolt cap is larger than the size of the elliptical hole in the middle position of the upper plane of the upper clamp block. The cap exerts a force on the upper surface of the upper clamp block, and the upper clamp block and the lower clamp block are pushed out from each other, so that the contact surfaces of the upper clamp and the lower clamp are at an angle of 40 ° to the work table of the mechanical device. After applying force, the upper clamp block slides in the direction of the 40 ° angle of the workbench of the mechanical device, and finally the force is transmitted from the tip of the upper clamp block to the work piece.

When the upper clamp block and the work piece are in close contact and no displacement occurs, the bolt is continuously turned to push it against the work piece. The tip pressure of the upper clamp block increases, and the work piece is firmly clamped and processed. The item cannot move up and down. At the same time, it becomes impossible to move sideways, and processing work can be done well.

3 When several independent clamp blocks (each clamp block can be called an inclined surface sliding jig of the present invention) are fixed to the workbench of the mechanical device by the above method, the inclined surface sliding jig of the present invention can be obtained. , The processed product can be firmly clamped and hardened, and the processed product cannot be moved up and down, and cannot be moved sideways, so that the processing work can be performed well.

The advantages of the present invention have become clear and are mainly shown as follows.

1 The design of the present invention is rational, the structure is simple, and if the processed product is fixed with a slide clamp, the work efficiency is considerably improved compared to the conventional clamping method, and the processed product can be moved up and down with a simple operation. , Clamping force acts in each direction on the left and right, and it can be fixed quickly and correctly.

2. The present invention can be applied to fixing processed products having various specifications by using a plurality of independent clamp blocks (tilted surface slide type jigs).

3 The 40 ° inclined surface of the clamp block of the present invention is a conclusion obtained after a long test, and the 40 ° inclined surface is the optimum inclined surface of the clamping force. By setting the inclined surface to 40 °, when the angle of the inclined surface is too small, the clamping force gradually decreases, and it is possible to prevent the processed product from becoming loose during machining work, and the angle of the inclined surface is large. In such a case, the clamping force is gradually increased, and it is possible to prevent the tip of the clamp from being easily pinched or deformed on the surface of the processed product.

4 The present invention has advantages such as a rational design, a novel structure, and convenient operation. It can be widely used in the machining industry and can be expected to bring positive social effects and significant economic effects to the machining industry.
