Description

Technical Field

[0001] The utility model relates to the technical field of inner support chuck processing, in particular to a clamp for inner support chuck processing. Background Art

[0002] Internal support chucks are commonly used in machining. They are a device for clamping the workpiece. They clamp the workpiece inside the chuck through an internal support rod or clamping device to ensure the stability and accuracy of the workpiece during the machining process. At the same time, the size of internal support chucks is not necessarily the same. The size of the internal support chuck is usually determined by the specific machining requirements and the size of the workpiece. Some internal support chucks may be designed to be adjustable in size to accommodate workpieces of different sizes, while others may be fixed in size and suitable for workpieces of a specific size range.

[0003] In the prior art, when the inner support chuck is being processed and produced, it is often necessary to fix and limit the inner support chuck to ensure the stability of the inner support chuck during production. Usually, an annular clamping block is used to limit the inner support chuck, and it is moved by means of a cylinder, a screw, etc. When the annular clamping block moves to the outside of the inner support chuck, the inner support chuck is limited and fixed. However, when the inner support chuck is produced, the sizes produced may be different. When a larger or smaller inner support chuck is needed, the clamping ring block needs to be replaced. The replacement of the clamping ring block not only reduces the efficiency of the inner support chuck production, but also requires preparing multiple clamping ring blocks for replacement, which is troublesome and inconvenient to operate.

[0023] In addition, the connection between the limiting rod 32 and the first movable plate 23 and the second movable plate 24 enables the first movable plate 23 and the second movable plate 24 to be smoothly limited by the limiting rod 32 when they move, and at the same time, the threads on both sides of the bidirectional screw 31 are opposite, so that when the bidirectional screw 31 rotates, it can smoothly drive the first movable plate 23 and the second movable plate 24 to move in opposite directions.

The workbench 1 can install and fix the fixed rod 6 through the limit groove 51, and the fixed rod 6 can limit the movement of the limit block 52 and the push block 35 through the connection between itself and the limit block 52, thereby increasing the stability of the limit block 52 and the push block 35 when moving.

[0027] See also Figure 1 : A reinforcement block 41 and a servo motor 42 are connected to one side of the first mounting plate 21. The output shaft of the servo motor 42 passes through the first mounting plate 21. The output shaft of the servo motor 42 is connected to the bidirectional screw 31 through a coupling. The reinforcement block 41 is connected to the outside of the servo motor 42. One of the first mounting plates 21 can play a role in installing and fixing the reinforcement block 41 and the servo motor 42.

A block 73 is connected to one end of the one-way screw 37, and the block 73 is connected to the inside of the slot 72. The setting of the extension rod 71 allows the staff to rotate the one-way screw 37 smoothly when needed, and makes it difficult for the one-way screw 37 to slide out from the inside of the first movable plate 23 or the second movable plate 24. At the same time, the setting of the slot 72 and the block 73 makes the installation and disassembly of the extension rod 71 convenient and simple.

[0030] It should be noted that: both ends of the fixing rod 6 are screwed to the workbench 1 through the limit groove 51, one side of the reinforcement block 41 and the servo motor 42 are screwed to one of the first mounting plates 21, the output shaft of the servo motor 42 is keyed to the bidirectional screw 31 through a coupling, the outer side of the servo motor 42 is screwed to the reinforcement block 41, one side of the second rubber layer 82 is bonded to the second clamping rod 38, one side of the first rubber layer 81 is bonded to the first clamping rod 36, the lower side of the rubber pad 83 is bonded to the workbench 1, one end of the one-way screw 37 is welded to the block 73, and the outer side of the block 73 is movably connected to the extension rod 71 through the slot 72.

[0031] Working principle: When the utility model is used, the staff can place the inner support chuck that needs to be processed on the upper side of the rubber pad 83. After placement, the staff can adjust the positions of the second clamping rod 38 and the first clamping rod 36 according to the size of the inner support chuck. When adjusting, the staff can start the servo motor 42. The servo motor 42 can drive the bidirectional screw 31 to rotate through its own operation. When the bidirectional screw 31 rotates, it can smoothly push the push block 35 through the rotating rod 34, and the push block 35 will also smoothly drive the first clamping rod 36 when being pushed. The rod 36 moves, and when the first clamping rod 36 is in contact with the inner support chuck, it can play a certain role in limiting and clamping the inner support chuck. After that, the staff can rotate the extension rod 71, and the extension rod 71 can smoothly drive the one-way screw 37 to rotate together. When the one-way screw 37 rotates, it can drive the second clamping rod 38 to move to one side of the inner support chuck. When the second clamping rod 38 is in contact with the inner support chuck, it can cooperate with the first clamping rod 36 to achieve the limiting and clamping of the inner support chuck, thereby improving the stability of the inner support chuck during processing.
