Description

Technical Field

[0001] This utility model belongs to the field of fixed tooling technology, specifically relating to a fixed tooling for rotary core filling. Background Technology

[0002] The turntable core fixing fixture is a special tool used to fix and position the turntable core in the online cutting process. Its core function is to ensure the stability of the turntable core during the online cutting process and prevent the turntable core from moving or falling off accidentally, thereby ensuring the safety and accuracy of the cutting operation.

[0003] Traditional rotary core fixing fixtures mostly use magnetic bases to hold the rotary cores in place for quick disassembly. This method works well with magnetic rotary core materials, such as some alloy steels, using magnetic attraction to firmly fix the rotary core to the fixture. However, rotary cores are made of a wide variety of materials, including not only magnetic materials but also non-magnetic or weakly magnetic materials such as cast steel and stainless steel. For these non-magnetic materials, fixtures relying solely on magnetic bases are insufficient for securing them.

[0004] Therefore, in order to solve the above problems, it is necessary to design a fixed fixture for rotary core filling. Utility Model Content

[0015] The first inclined surface portion is adapted to the second inclined surface portion; and

[0016] The second inclined surface is adapted to slide on the first inclined surface to cause the clamping block to press against the outer wall of the turntable core.

[0017] Furthermore, the first and second inclined surfaces are arc-shaped;

[0018] The other side of the clamping block is provided with an arc-shaped portion; wherein

[0019] The arcuate portion is adapted to contact the outer wall of the turntable core; and

[0020] The first inclined surface and the outer wall of the turntable core are suitable for positioning the clamping block.

[0021] Furthermore, the clamping block has a long countersunk through hole in the middle;

[0022] The base plate is provided with threaded holes;

[0023] The countersunk hole and threaded hole are equipped with internal hex bolts; wherein

[0024] The socket head cap screw is adapted to pass through a long countersunk hole and then be threaded into a threaded hole; and

[0025] The second inclined surface is adapted to allow the internal hex bolt to move relative to the long countersunk through hole when sliding on the first inclined surface.

[0026] Furthermore, the base plate is provided with several countersunk through holes; wherein

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0041] like Figures 1 to 3 As shown, this embodiment provides a fixing fixture for turntable core filling, including:

[0042] Two horizontally arranged base plates 1 are not in contact with each other; two symmetrically arranged semi-cylinders 2 are respectively set on the corresponding base plates 1 and respectively contact the inner wall of the turntable core; two symmetrically arranged clamping blocks 3 are respectively bolted to the corresponding base plates 1 and respectively contact the outer wall of the turntable core; wherein the clamping blocks 3 are adapted to cooperate with the semi-cylinders 2 to fix the turntable core; wherein the two base plates 1 are not in contact with each other, thereby facilitating wire cutting processing; wherein the two semi-cylinders 2 are set to support the inner wall of the turntable core; wherein the semi-cylinders 2 are bolted to the base plates 1, which is the most preferred method.

[0043] In this embodiment, the turntable core is placed on the outside of the two semi-cylinders 2, with its inner wall fitting against the cylindrical surface of the semi-cylinders. It is bolted to the base plate 1 by the clamping block 3, so that the clamping block 3 is in close contact with the outer wall of the turntable core. The bolt preload cooperates with the semi-cylinders 2 to apply radial clamping force to the outer wall of the turntable core, forming a composite fixing mode of "inner support and outer clamping", thereby achieving the effect of fixing the turntable core, while eliminating the need to consider the material of the turntable core.

[0044] Both base plates 1 are provided with fixing blocks 4; the two fixing blocks 4 are symmetrically arranged; the side of the fixing block 4 is provided with a first inclined surface 401; the side of the clamping block 3 is provided with a second inclined surface 301; wherein the first inclined surface 401 and the second inclined surface 301 are adapted to each other; and the second inclined surface 301 is adapted to slide on the first inclined surface 401 so that the clamping block 3 presses against the outer wall of the turntable core; by setting the first inclined surface 401 and the second inclined surface 402 to be adapted to each other, and the second inclined surface 301 can slide on the first inclined surface 401, the axial force of the bolt is converted into a radial clamping force to realize the conversion of the force direction so that the clamping block 3 is in close contact with the outer wall of the turntable core.

[0045] The first inclined surface 401 and the second inclined surface 301 are arc-shaped; the other side of the clamping block 3 is provided with an arc-shaped portion 302; wherein the arc-shaped portion 302 is adapted to contact the outer wall of the turntable core; and the first inclined surface 401 and the outer wall of the turntable core are adapted to position the clamping block 3; by setting the first inclined surface 401 and the second inclined surface 301 to be arc-shaped, the first arc-shaped positioning is achieved, and the other side of the clamping block 3 is provided with an arc-shaped portion 302 to contact the outer wall of the turntable core, so as to achieve the second arc-shaped positioning, thereby preventing the clamping block 3 from shifting when moving.

[0046] The clamping block 3 has a long countersunk through hole 303 in the middle; the base plate 1 has a threaded hole 101; the long countersunk through hole 303 and the threaded hole 101 are provided with hexagon socket bolts 5; wherein the hexagon socket bolts 5 are adapted to pass through the long countersunk through hole 303 and be threadedly connected to the threaded hole 101; and the second inclined surface 301 is adapted to slide on the first inclined surface 401, and the hexagon socket bolts 5 move relative to each other in the long countersunk through hole 303.

[0047] In this embodiment, when the socket head cap screw 5 passes through the long countersunk hole 303 and is screwed into the threaded hole 101, the socket head cap screw 5 presses down on the clamping block 3. The second inclined surface 301 of the clamping block 3 slides downward on the first inclined surface 401. At this time, the clamping block 3 moves closer to the turntable core until the arc part 302 is in close contact with the turntable core. At the same time, the position of the long countersunk hole 303 also moves. Since it is a long countersunk hole 303, it will not affect the normal locking of the socket head cap screw 5.

[0048] The base plate 1 is provided with a plurality of countersunk through holes 102; wherein each of the countersunk through holes 102 is arranged in a rectangular array; wherein by providing countersunk through holes 102, it is easy to fix the base plate 1 to the processing table with bolts.
