[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0019] like Figure 1As shown, the utility model provides a press-type tooling for an external cylindrical lathe, comprising a clamping assembly 100 and a connecting assembly 200, the clamping assembly 100 comprising a first clamping plate 110 and a second clamping plate 120, the first clamping plate 110 and the second clamping plate 120 are detachably connected, and a clamping gap for fixing a product is formed therebetween, the connecting assembly 200 connects the first clamping plate 110 and the three-jaw chuck of the lathe, the connecting assembly 200 and the first clamping plate 110 are detachably connected, via the detachable connection between the connecting assembly 200 and the first clamping plate 110, and the detachable connection between the first clamping plate 110 and the second clamping plate 120, the first clamping plate 110 and the second clamping plate 120 of different sizes can be replaced to adapt to products of different sizes.

[0020] During implementation, the first clamping plate 110 connected to it can be fixed on the three-jaw chuck of the lathe through the connecting component 200. At the same time, the product can be clamped and fixed along the thickness direction of the product by the first clamping plate 110 and the second clamping plate 120. Through the detachable connection between the connecting component 200 and the first clamping plate 110, and the detachable connection between the first clamping plate 110 and the second clamping plate 120, the first clamping plate 110 and the second clamping plate 120 of different sizes can be replaced to adapt to products of different sizes.

[0021] The clamping assembly 100 in this embodiment includes a first clamping plate 110 and a second clamping plate 120 . The first clamping plate 110 and the second clamping plate 120 are detachably connected, and a clamping gap for fixing the product is formed therebetween.

[0022] The connecting assembly 200 in this embodiment connects the first clamping plate 110 and the three-jaw chuck of the lathe, and the connecting assembly 200 and the first clamping plate 110 are detachably connected.

[0023] In one embodiment, the connecting assembly 200 includes a connecting block 210 and a locking block 220. The connecting block 210 is connected to the three-jaw chuck of a lathe. The locking block 220 is arranged at a position between the first clamping plate 110 and the second clamping plate 120, and is embedded in a groove 111 opened on the first clamping plate 110. The connecting block 210 and the locking block 220 are detachably connected.

[0024] In order to achieve a detachable connection between the connecting block 210, the locking block 220 and the first clamping plate 110, in one embodiment, the connecting assembly 200 also includes a plurality of first connecting screws 230, which sequentially pass through a plurality of first through holes 221 opened on the locking block 220 and a plurality of second through holes 112 opened on the first clamping plate 110, and are respectively threadedly connected to the plurality of first threaded holes 211 opened on the connecting block 210.

[0025] It should be noted that the depth of the groove 111 should be sufficient to allow the locking block 220 and the first connecting screw 230 to be completely built into the groove 111 to avoid interference between the locking block 220 and the first connecting screw 230 and the product located in the clamping gap.

[0026] In one embodiment, the connecting block 210 and the locking block 220 are both disc-shaped structures, and the plurality of first connecting screws 230 are evenly arranged along the circumference of the locking block 220 .

[0027] It is understandable that the connecting block 210 and the locking block 220 may also adopt other shapes, such as square, triangle, etc., wherein the shape and size of the locking block 220 should be compatible with the shape and size of the groove 111 to ensure that the locking block 220 cannot rotate circumferentially in the groove 111.

[0028] To achieve a detachable connection between the first clamping plate 110 and the second clamping plate 120 , in one embodiment, the clamping assembly 100 further includes a second connecting screw 130 , which passes through a third through hole 121 formed on the second clamping plate 120 and is connected to a second threaded hole 222 formed on the locking block 220 .

[0029] It should be noted that the second connecting screw 130 is located at the center of the first clamping plate 110 and the second clamping plate 120 to ensure that the first clamping plate 110 and the second clamping plate 120 are evenly stressed.

[0030] To further improve the stability of the connection between the first clamping plate 110 and the second clamping plate 120, in one embodiment, the clamping assembly 100 further includes a second connecting screw 140, through which the second connecting screw 130 is disposed, and two sides of the second connecting screw 140 are respectively in contact with the nut of the second connecting screw 130 and the second clamping plate 120. The second connecting screw 140 can evenly transfer the pressure applied by the nut of the second connecting screw 130 to the second clamping plate 120.

[0031] In one embodiment, the first clamping plate 110 and the second clamping plate 120 are both disc-shaped structures with the same diameter. The outer circumference of the product disposed therein is located outside the first clamping plate 110 and the second clamping plate 120 to facilitate subsequent machining operations.

[0032] In one embodiment, an annular groove 113 is formed at the extension of one side of the first clamping plate 110 close to the second clamping plate 120 to fit the annular product, wherein the depth of the annular groove 113 is the same as the thickness of the product.

[0033] In one embodiment, the second clamping plate 120 is made of POM material, wherein the POM material is a blue polyoxymethylene material having excellent mechanical strength, rigidity and wear resistance, capable of bearing weight and pressure, and having good corrosion resistance when the equipment uses cutting oil.

[0034] At the same time, the color of the second clamping plate 120 is different from that of the first clamping plate 110, which can avoid taking the wrong clamping plate and facilitate installation.

[0035] Compared with the prior art: the first clamping plate 110 connected thereto can be fixed on the three-jaw chuck of the lathe through the connecting component 200, and at the same time, the product can be clamped and fixed along the thickness direction of the product through the first clamping plate 110 and the second clamping plate 120, and through the detachable connection between the connecting component 200 and the first clamping plate 110, and the detachable connection between the first clamping plate 110 and the second clamping plate 120, the first clamping plate 110 and the second clamping plate 120 of different sizes can be replaced to adapt to products of different sizes.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
