Abstract

PURPOSE:To reduce labor for machining electrical parts or the like in the case of household work by providing a work indexing rotary device which can be rotated without any power source only by changing a machining table and a pressing rod according to the type of the work to be machined. CONSTITUTION:A turntable 2 is mounted in the center of a turn base 1, and a work machining table 16 is mounted on the upper face of the turntable. J-shaped convex portions 4 are provided around the peripheral face of the turntable. When a work pressing rod 9 provided separately for the base 1 is pressed against the portion 3 to be machined a sliding rod 10 is lowered, sliding in the recess between the J-shaped convex portions 4 on the peripheral face of the turntable. A sliding nail 11 housed in the lower portion of the rod 10 by spring is withdrawn into the sliding rod 10 when pressed by the top protrusion of the J-shaped convex portions 4, and is protruded at the aded point of its lowering movement to make contact with right hand step B of the J-shaped convex portions 4. And as the sliding rod 10 moves upwards, the turntable 2 is rotated clockwise by one step to be ready to start machining the next work portion 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous workpiece indexing and rotation device used in a processing device for mainly electrical parts and other small articles that can be processed inside a house.

Conventionally, when processing large quantities of the same type of product, large-scale electric drive or compressed air has been used as processing means, and the rotating means for positioning the workpiece is also very expensive. No suitable device has been seen on the market that is powered by such power and can be easily handled at home.

Focusing on these points, the present invention has been developed as a continuous processing device for small items such as press braces, and even if the processing of the workpiece itself is done manually, and even when using an electric motor etc., the device itself is It is an ultra-compact and lightweight device that eliminates the need for air or electric sources to move the workpiece mounting table.

An embodiment of the workpiece indexing and rotating device according to the present invention will be described based on the drawings. In FIG. A workpiece processing stand 16 is mounted on the upper surface of the turntable 2 and can be replaced as appropriate depending on the type of processing of the crop. This is fixedly integrated with the lower surface of the processing table 16 using, for example, a fitting pin 17, and is placed closely in the fitting hole of the turntable 2, and the surface of the cutting table 16 is used to accommodate the corrugated workpiece. Processed portions 6 are arranged at equal intervals on the inner side of the periphery.

A J-shaped protrusion is provided on the peripheral side of the turntable 2,
It is provided on the periphery of the processing table at a distance equal to the thickness of the upper part.

The turntable 2 has fixing holes 5 cut in the lower circumference in a number equal to the number of workpiece processing parts 6, and the position fr:t G'
31 The positioning device 6 allows for secure positioning during processing.

Separately, a support (not shown) is fixed to the support 1i'-, and a workpiece processing press rod 9 and a slide 'j' are attached to this support.
t210 is set so that it can move up and down, and the press rod 9 is pressed against the processing part B (moves downward).
At this time, the slide 810 slides down the concave portion on the circumference of the turntable between the J-shaped protruding surfaces 4.4.

At this time, the slide wind 11 (shown in Figures 2 and 4) housed in the lower part of the slide rod 10 in a spring manner is pushed by the bulge at the tip of the J-shaped protrusion 4 by the lower slope of the slide rod 10, and the slide rod 10, the claw 11 protrudes from the dead center of the downward movement (sliding f from the tip of the J-shaped protruding surface part 4 (when it comes off the A side of 11), and touches the right side of the J-shaped protruding surface part 4 As the slide rod 10 moves upward, the turntable 2 rotates one frame clockwise (clockwise direction of the turntable) and moves on to the next processing section B.

The shafts 15 of the turntable 2 and the mounting table 1 are completely fixed with sliding screws depending on the size and weight of the table 2.

Next, referring to FIGS. 2, 6, and 4, the slide 1 (11 has a side structure as shown in FIG. It is retracted by the step of the surface portion 4 by the action of the spring 14. The spring holding plate 12 is fixed to the slide rod 10 with screws 16.

When the slide wind 11 is viewed from the front (FIG. 2), it forms a diagonal line part A along three sides of the J-shaped protrusion part 4.

Further, when viewed from the upper surface south of ε 134, the surface of the slide wind 11 has an arc shape along the curved surface of the turntable 2.

Next, the front view of the turntable 2 and the mounting table 1 in FIG.
When looking at the cut surface, it can be seen that the fixing hole 57 is engaged with the fixing device B.

FIG. 6 shows a position fixing device 6, in which 7 is a protrusion that engages with the fixing hole 5 of the turntable 2, and is used to smoothly move and fix the table 2 by means of a spring 8.

No. 7N indicates a workpiece processing table 16, and a single dowel pin 17 is formed on the lower surface thereof to be closely stabilized in a hole (not shown) drilled in the surface of the turntable 2.

As described above, the workpiece indexing and rotation device according to the present invention is highly labor-saving without using any large-scale power source to rotate the turntable, and can easily process workpieces at home. It is a device that can be used quickly by easily replacing the processing table and press bar depending on the type of workpiece.

The workpiece is mainly used for pressing, molding, assembling, drilling, etc. of metal products, but it can also be used for processing plastics and the like.
