Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a fixture for solid cylindrical parts. Background Art

[0002] Among the cylindrical workpieces encountered in machining, most are machining blanks or need to be machined into cylindrical workpieces. For larger-sized cylindrical workpieces, their own mass is relatively large, so there is a problem of inconvenient transfer. Secondly, if the lifting and transfer method is adopted, it is very difficult to be fixed due to the existence of the arc surface, so safety accidents are likely to occur during transfer, and the lifting method is the commonly used method for handling cylindrical workpieces at present. Summary of the Utility Model

[0003] The utility model provides a fixture for solid cylindrical parts to solve the above-mentioned deficiencies of the prior art, solve the stability and reliability of cylindrical workpieces during lifting and transfer, and has strong practicability.

[0004] In order to achieve the purpose of the utility model, the following technology is proposed:

[0005] A fixture for solid cylindrical parts includes a disc. There are three support plates on the disc. Rectangular openings are formed on the support plates. A hook is provided on the disc, and the hook on the lifting device can be hooked on the hook, thus facilitating the transfer operation of the cylindrical workpiece. An activity seat is movably arranged in the rectangular opening. A connecting arm is hinged on the activity seat. A central shaft is coaxially arranged on the disc. A rotating sleeve is rotatably arranged on the central shaft. A rotating disc is arranged at the inner end of the rotating sleeve. At least three convex plates are arranged on the outer periphery of the rotating disc. The other end of the convex plate is hinged to the other end of the connecting arm. A limiting nut is arranged at the outer end of the central shaft. The rotating sleeve is located inside the limiting nut. The limiting nut can limit the rotation angle of the rotating sleeve, thereby achieving the purpose of fixing the position of the activity seat. A rotating shaft is rotatably arranged on the activity seat. A limiting column is arranged at one end of the rotating shaft. A connecting screw is arranged at the other end of the limiting column. A limiting end plate is arranged at the other end of the connecting screw. A pair of nuts are arranged on the connecting screw. The nuts are located on both sides of the limiting end plate. A swinging plate is fixed at the other end of the rotating shaft. A convex sleeve plate is arranged on the activity seat. A limiting sleeve is movably arranged on the convex sleeve plate. The limiting sleeve is sleeved on the swinging plate. The limiting sleeve can limit the rotation of the swinging plate to ensure safety during transfer. The limiting end plate and the disc can limit the two ends of the workpiece, and ensure safety during transfer through the limit. The provided limiting column can act on the outer periphery of the cylindrical workpiece, further improving safety during transfer to prevent the cylindrical workpiece from moving within the limiting column during the transfer process.

[0006] Further, limiting plates are arranged on both sides of the activity seat. The limiting plates are located on both sides of the support plate to guide and limit the movement of the activity seat.

[0007] Further, a tightening screw is provided on the rotating sleeve, and the inner end of the tightening screw abuts against the outer periphery of the central shaft to lock the rotation angle of the rotating sleeve, and further improve the stability after limiting.

[0008] Further, a swing rod is provided at the outer end of the swing plate, which is convenient for the operator to perform the limiting operation on the cylindrical workpiece.

[0009] Further, an end stop block is provided at the outer end of the convex sleeve plate to prevent the limiting sleeve from detaching from the convex sleeve plate.

[0010] The advantages of the above technical solutions are as follows:

[0011] When the utility model is hoisted and transferred, it can stably restrain and limit the cylindrical workpiece, thereby improving the safety during transfer. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0014] Figure 2 The enlarged view at A is shown. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] As Figures 1 to 2 shown, a fixture for a solid cylindrical part includes a disc 1, a hook 10 is provided on the disc 1, three support plates 11 are provided on the disc 1, and a rectangular opening 12 is formed on the support plate 11.

[0016] A movable seat 26 is movably provided in the rectangular opening 12, limiting plates are provided on both sides of the movable seat 26, the limiting plates are located on both sides of the support plate 11, a connecting arm 25 is hinged on the movable seat 26, a central shaft 2 is coaxially provided on the disc 1, a rotating sleeve 20 is rotatably provided on the central shaft 2, a tightening screw 23 is provided on the rotating sleeve 20, the inner end of the tightening screw 23 abuts against the outer periphery of the central shaft 2, a turntable 21 is provided at the inner end of the rotating sleeve 20, at least three convex plates 22 are provided on the outer periphery of the turntable 21, the other end of the convex plate 22 is hinged to the other end of the connecting arm 25, a limiting nut 24 is provided at the outer end of the central shaft 2, and the rotating sleeve 20 is located inside the limiting nut 24.

[0017] A rotating shaft 3 is rotatably provided on the movable seat 26. One end of the rotating shaft 3 is provided with a limit post 32. The other end of the limit post 32 is provided with a connecting screw 33. The other end of the connecting screw 33 is provided with a limit end plate 34. A pair of nuts 35 are provided on the connecting screw 33. The nuts 35 are located on both sides of the limit end plate 34. The other end of the rotating shaft 3 is fixed with a swing plate 30. The outer end of the swing plate 30 is provided with a swing rod 31. A convex sleeve plate 27 is provided on the movable seat 26. The outer end of the convex sleeve plate 27 is provided with an end stop 28. A limit sleeve 29 is movably provided on the convex sleeve plate 27. The limit sleeve 29 is sleeved on the swing plate 30.

[0018] In this embodiment, when transferring the cylindrical workpiece, the operator inserts the connecting screw 33 on the outer periphery of the vertically placed cylindrical workpiece, or can also insert it on the horizontally placed cylindrical workpiece.

[0019] Then the operator loosens the limit nut 24 and tightens the screw 23, and rotates the turntable 21 through the hook 10. The rotation of the turntable 21 will pull each movable seat 26 closer to the cylindrical workpiece through the connecting arm 25, and make the limit post 32 closely adhere to the outer periphery of the workpiece. After the adjustment is completed, the operator fixes and locks the rotating sleeve 20 through the limit nut 24 and the screw 23.
