Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-3, a casting fixture for a machine tool comprises a fixture table 1, a chute 10 is formed in the fixture table 1, a slide block 12 is slidably connected in the chute 10, a threaded rod 2 is fixedly connected to one side of the slide block 12, a rotating handle 3 is fixedly connected to the threaded rod 2, a threaded hole 14 matched with the threaded rod 2 is formed in one side of the fixture table 1, a first fixture 8 is fixedly connected to the slide block 12, a clamping block 9 is fixedly connected to one side of the first fixture 8, a long rod 4 is fixedly connected to the other side of the first fixture 8, a penetrating limiting hole 5 is formed in one side of the long rod 4, a limiting rod 6 is movably installed in the limiting hole 5, a nut 11 is rotatably connected to one side of the limiting rod 6, an elongated slot 13 is formed in the inner wall of the long rod 4, a second fixture 7 is sleeved on the limiting rod 6, and the second fixture 7 slides in the elongated slot 13;

the specific working principle and implementation mode are as follows: the arrangement is that a small product to be cast is placed in the fixture table 1, an operator holds the rotating handle 3 to rotate the threaded rod 2 to drive the sliding block 12 to rotate inwards, the upper end of the sliding block 12 is fixedly connected with the first fixture 8, the sliding block 12 drives the first fixture 8 to push inwards through the threaded hole 14, then the product to be clamped is clamped through the clamping block 9, the product to be clamped is small in size, when the first fixture 8 is pushed inwards, the long rod 4 is driven to push inwards together, the product is small in size, the second fixture 7 can slide onto the first fixture 8, then the product is movably installed in the limiting hole 5 through the limiting rod 6, then the second fixture 7 is fixed through the rotating nut 11, when the product to be clamped is long and large in size, the rotating handle 3 rotates the threaded rod 2 to drive the sliding block 12 and the first fixture 8 to rotate outwards to a position capable of clamping the product, then the product is clamped through the two clamping blocks 9 on the outermost sides of the clamping blocks 9, then the fixture 4 is fixedly connected to one side of the first fixture 8, when the product to be clamped is long and the long and large in size, when the product to be clamped, the sliding through the sliding block 8, the sliding block 8 and the sliding rod 2 can slide outwards through the sliding block 4, the long rod 2, and the long rod 2 can slide into the long rod 7, and can slide into the long rod 2, and can be further, and can be clamped through the long rod 2, and can be further tightened after the long rod 2, and can be clamped in the long rod 4, and can be clamped through the long rod 2, and can be further tightened in the long rod 4, and can be further.

As shown in fig. 1 and 2, the plurality of limiting holes 5 are provided, so that the limiting holes 5 are provided, when the first clamp 8 and the second clamp 7 need to clamp products with different lengths, because the long rod 4 is fixedly connected with the first clamp 8, the penetrating limiting holes 5 are provided on one side of the long rod 4, when the products with different lengths need to be clamped, the second clamp 7 can move along with the movement of the first clamp 8, the second clamp 7 slides in the long groove 13 in the long rod 4, the products with different lengths can be used, the limiting rod 6 slides to the limiting holes 5 to a proper position, and the second clamp 7 is fixed.

As shown in fig. 1 and 2, the clamping block 9 is also fixed in the second clamp 7, which is arranged because when the length of a product to be clamped is long, the second clamp 7 slides in the long groove 13, the second clamp 7 is adjusted to a proper position, the limiting rod 6 penetrates through the limiting hole 5 and the second clamp 7, then the second clamp is screwed by the nut 11, and when the clamping block 9 is also fixed in the second clamp 7, the product with long length can be better clamped.

As shown in fig. 1 and 2, the second fixture 7 and the first fixture 8 are hollow, which is arranged because, when the fixture table 1 needs to be moved, the first fixture 8 and the second fixture 7 are hollow, so that the use of iron can be reduced, and the fixture table 1 can be better transported, and when the second fixture 7 is hollow, the second fixture 7 needs to be adjusted to clamp longer products, and because the use of iron is reduced, the second fixture 7 can be better adjusted and moved.

As shown in fig. 1, fig. 2 and fig. 3, the cover is equipped with the antiskid cover on the rotating handle 3, the setting is because, when the first anchor clamps 8 need the less product of centre gripping to cast, because the first anchor clamps 8 of fixedly connected with on the slider 12, when the centre gripping of first anchor clamps 8 is needed, need to rotate the handle 3 and drive the slider 12 and inwards push first anchor clamps 8 through spout 10, when the rotatory rotating handle 3, the cover is equipped with the antiskid cover on the rotating handle 3, can make operating personnel be infected with the spot on the product after the casting on hand after, can not the hand smooth when rotating the rotating handle 3, lead to first anchor clamps 8 not inseparabler centre gripping the product of will casting.

As shown in fig. 3, the cover is equipped with the antiskid cover on the clamp splice 9, sets up like this because, when 8 centre gripping products of first anchor clamps of needs, because clamp splice 9 fixed connection is on first anchor clamps 8, when the product of clamp splice 9 contact needs casting centre gripping, the cover is equipped with the antiskid cover on the clamp splice 9, can make the product centre gripping more firm to needs casting centre gripping that first anchor clamps 8 are better, at the difficult slip of product at cast in-process.

Finally, it should be noted that: in the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
