Rotary table capable of being used for machining knock-over plate

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0023] like Figure 1 to Figure 7 A schematic structural diagram of a rotary table that can be used to process knock-off plates shown, has a base 1 installed on a machine tool guide rail, two ends of the base 1 are fixedly connected with a fixed seat 2, and the two fixed seats 2 are connected by bearings. There is a freely rotatable rotating shaft 3, the surface of the outer ring of the rotating shaft 3 is formed with a horizontal tangent plane along the axial direction, and the horizontal tangent plane is elongated in the shape of a rectangle. The plate seat plate 4 is provided with 5 clamping devices 5 for fixing the de-ring plate on the side of the de-ring plate seat plate 4;

[0024] Positioning plates 6 are fixedly installed at both ends of the rotating shaft 3. In order to make the installation position of the positioning plate 6 more reasonable, the positioning plate 6 is bolted to the stepped surface of the rotating shaft 3 facing the side of the fixed seat 2, and the positioning plate 6 and the fixed seat are connected between the positioning plate 6 and the fixed seat. 2 are respectively provided with a plurality of positioning holes 9; when the positioning plate 6 is in a horizontal state, there are two matching positioning holes 9 on the positioning plate 6 and the fixing base 2, and the positioning pins pass through the two holes to make it fixed; When the positioning plate 6 is at a forward rotation of 25°, the positioning plate 6 and the fixing base 2 also have two paired positioning holes 9, and the positioning plate 6 is fixed by passing the positioning pins through the two holes; when the positioning plate 6 is reversed At 25°, the positioning plate 6 and the fixing base 2 also have two paired positioning holes 9, and the positioning plate 6 is fixed by passing the positioning pins through the two holes;

[0025] When the positioning plate 6 needs to be in a horizontal state, the positioning pins pass through the positioning holes 9 on the positioning plate 6 and the fixed seat 2 to keep it horizontal; when the positioning plate 6 needs to be in a positive rotation angle of 25°, The positioning pin shaft passes through the positioning plate 6 and the two matching positioning holes 9 on the fixed base 2 to keep it rotated 25° forward; when the positioning plate 6 needs to be at a rotation angle of reverse 25°, the positioning pin shaft passes through the positioning The two paired positioning holes 9 on the plate 6 and the fixing base 2 keep it reversed by 25°; the above 3 rotation angle positions are only for preference, and the present invention is not limited to these 3 positions, because the rotation axis 3 can be 360°. It can rotate freely, and the positioning plate 6 is fixedly connected with the rotating shaft 3. The rotating shaft 3 clamps the processed knock-off plate. Therefore, any desired rotation can be formed between the positioning plate 6 and the fixed seat 2. Angle, without re-clamping the stripping plate, the inclined slope can be machined on the stripping plate, reducing the number of clamping times, avoiding machining errors and causing the parts to be scrapped.

[0026] The clamping device 5 includes a slot plate 51 and a pressure plate 52 bolted on the slot plate 51 for restricting the upward movement of the knock-off plate to be processed. And it is fixedly connected with the knock-off plate seat plate 4, and part of the upper surface of the knock-off plate seat plate 4, the side surface of the card slot plate 51 and the part of the lower surface of the pressing plate 52 form a workpiece clamping groove 53 for clamping the knock-off plate to be processed. , and a baffle plate 8 that restricts the displacement of the stripping plate is fixedly installed at the side of the stripping plate seat plate 4 on the adjacent side of the clamping device 5, and the slot plate 51 restricts the stripping plate along the rotation axis. 3. Movement in the radial direction, the pressure plate 52 and the knock-off plate seat plate 4 limit the movement of the knock-off plate in the upper and lower directions, and the baffle plate 8 on one side restricts the movement of the knock-off plate in the axial direction of the rotating shaft 3, Therefore, using the knock-off plate for fixed positioning through the slot plate 51, the pressing plate 52 and the baffle plate 8 can effectively prevent it from shifting during work.

[0027] In addition, in order to increase the strength of the rotating shaft 3, two intermediate support seats 7 are arranged on the base 1 located below the rotating shaft 3. The intermediate support seats 7 have an inner groove arc surface concentric with the rotating shaft 3, and the inner groove arc surface is provided with There is a bearing bush 71 connected with the rotating shaft 3 , and the rotating shaft 3 rotates freely on the bearing bush 71 to avoid direct contact with the support seat and prolong the service life of the support seat and the rotating shaft 3 .

[0028] The invention can process the knock-off plate or similar workpieces at one time, avoid the errors caused by disassembly, reduce manpower and material resources, shorten the production cycle, reduce the processing errors, and avoid the waste of parts.

[0029] Taking the above ideal embodiments according to the present invention as inspiration, and through the above description, relevant personnel can make various changes and modifications without departing from the technical idea of ​​the present invention. The technical scope of the present invention is not limited to the contents in the specification, and the technical scope must be determined according to the scope of the claims.
