Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cast steel parts processing, and in particular to a deformation-resistant clamping fixture for cast steel parts processing. Background Technology
[0002] Cast steel parts are components or blanks made primarily of steel and produced using casting methods, possessing specific shapes, dimensions, and performance requirements. They combine the excellent mechanical properties of steel with the complex forming advantages of casting, enabling the manufacture of products with complex shapes that are difficult to form using other processing methods.
[0003] Existing clamping fixtures for machining cast steel parts typically use two sets of clamps to hold both sides of the cast steel part. However, when the cast steel part is being cut, the cutting of the cast steel part will generate a downward force. One end of the cast steel part is clamped, and the other end is cut and generates a downward force, which may cause the cast steel part to deform and affect the quality of the finished product to a certain extent. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-deformation clamping fixture for the processing of cast steel parts.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A deformation-resistant clamping fixture for machining cast steel parts includes a worktable. A double-ended threaded rod is rotatably connected to the worktable. Two sets of frames are threadedly connected to the double-ended threaded rod. Two sets of double-ended threaded rods are rotatably connected to each set of frames. Two sets of plates are threadedly connected to each set of double-ended threaded rods. A groove is opened at one end of each set of frames. Plates are movably inserted through each groove. A threaded rod is threaded at one end of each set of plates. A block is connected to one end of each set of threaded rods. A ball is movably connected to one end of each set of blocks. A motor is installed at one end of the worktable, and the output end of the motor is connected to the double-ended threaded rod.
[0007] Preferably, both sets of plates have multiple sets of holes, and both sets of frames are threaded with bolts, with the bolts threadedly connected to the corresponding holes.
[0008] Preferably, each of the two sets of plates is rotatably connected to a wheel at one end, and each set of wheels is in contact with one end of the worktable.
[0009] Preferably, each of the two sets of threaded rods and the two sets of double-ended threaded rods has a handwheel connected to one end.
[0010] Preferably, a rod is connected to the workbench, and the rod is slidably connected to two sets of frames. Each set of frames is connected to a round rod, and the two sets of round rods are slidably connected to a corresponding plate.
[0011] Preferably, one end of the workbench is connected to an arc-shaped plate, which movably passes through the two sets of frames, and the double-headed threaded rod is located below the arc-shaped plate.
[0012] Preferably, each of the multiple sets of plates is connected to a rubber pad at one end.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. By cooperating with the threaded rod, ball and plate, the double-ended threaded rod clamps the two sides of the cast steel part. Rotating the threaded rod moves the block, which in turn moves the ball to fit the cast steel part, thus supporting it. This multi-point support avoids the problem of deformation that may occur when the cast steel part is cut during machining, such as when one end is clamped and the other end is subjected to downward force due to gravity. This improves the quality of the finished product to a certain extent.
[0015] 2. By using the set bolts, plate two, and groove, the bolts are unscrewed from plate two, the movement restriction on plate two is removed, and plate two is moved along the groove, thereby adjusting the position of the ball. The support point of the ball on the cast steel part is adjusted according to the actual situation to avoid affecting the processing of the cast steel part. It has a wide range of applications to a certain extent. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1, referring to Figures 1 to 5 A deformation-resistant clamping fixture for machining cast steel parts includes a worktable 1. A double-threaded rod 1 2 is rotatably connected to the worktable 1. Rotating the double-threaded rod 1 2 moves the frame 3, thereby adjusting the position of the plate 5 according to the size of the cast steel part. Two sets of frame 3 are threadedly connected to the double-threaded rod 1 2. Two sets of double-threaded rods 2 4 are rotatably connected to each set of frame 3. Rotating the double-threaded rods 2 4 moves the plate 5, clamping the cast steel part. Two sets of plate 5 are threadedly connected to each set of double-threaded rods 2 4. The plate 5 is L-shaped, which can better clamp the cast steel part to a certain extent. A groove 6 is opened at one end of each set of frame 3. A plate 2 7 is movably inserted through each set of grooves 6. A threaded rod 8 is threadedly connected to one end of each set of plate 2 7. Rotating the threaded rods 2 4... Rod 8 moves block 9, which in turn causes ball 10 to fit against the cast steel part. One end of each of the two sets of threaded rods 8 is connected to block 9, and one end of each of the two sets of block 9 is movably connected to ball 10. Ball 10 can rotate, which can better adapt to the shape of the cast steel part. A motor 13 is installed at one end of the worktable 1. The model of motor 13 can be selected according to actual needs. The output end of motor 13 is connected to double-ended threaded rod 2. Motor 13 drives double-ended threaded rod 2 to rotate. The ball 10 provides multi-point support for the cast steel part, which to a certain extent avoids the problem that when the cast steel part is cut, some areas are cut and the downward force generated by gravity, while one end of the cast steel part is clamped. The conflict between the two may cause deformation, which improves the quality of the finished product to a certain extent.
[0024] In this embodiment, both sets of plates 7 have multiple sets of holes 11, and both sets of frames 3 are threaded with bolts 12. The bolts 12 are threaded into the corresponding holes 11. Unscrewing the bolts 12 removes the restriction on the plates 7, allowing them to move and adjust the position of the ball 10, thus preventing the ball 10 from affecting the machining of the cast steel parts. This design offers a wide range of applicability. Each set of plates 7 has a rotatable wheel 14 at one end, which fits against one end of the worktable 1, providing support to the plates 7. Each set of threaded rods 8 and each set of double-ended threaded rods 4 has a handwheel 15 at one end, facilitating rotation of the threaded rods 8 and 4. A rod 16 is connected to the workbench 1, and the rod 16 is slidably connected to two sets of frames 3, guiding the frames 3. A round rod 17 is connected to each set of frames 3, and the two round rods 17 are slidably connected to their corresponding plates 5, guiding the plates 5. An arc-shaped plate 18 is connected to one end of the workbench 1, and the arc-shaped plate 18 movably passes through the two sets of frames 3. A double-threaded rod 2 is located below the arc-shaped plate 18. The arc-shaped plate 18, to a certain extent, prevents debris generated during the processing of the cast steel parts from falling onto the double-threaded rod 2. Rubber pads 19 are connected to one end of each set of plates 5, improving clamping stability to a certain extent.
[0025] The working principle of this embodiment is as follows: When in use, the starter motor 13 drives the double-headed threaded rod 2 to rotate, which in turn moves the frame 3. This allows the frame 3 to adjust the position of the cast steel part. The double-headed threaded rod 4 rotates, which moves the plate 5 to clamp the cast steel part. The threaded rod 8 rotates, which moves the ball 10 through the block 9 and makes it fit against the cast steel part, providing multi-point support for the cast steel part. This avoids the problem of the cast steel part deforming due to the downward force generated by gravity at the cut-off part and the clamping at one end during cutting, thus improving the quality of the finished product to a certain extent. The bolt 12 is then unscrewed, and the plate 7 is moved according to the actual situation to adjust the position of the ball 10, so that the ball 10 does not affect the processing of the cast steel part. This method has a wide range of applications.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
