AI Technical Summary
During the processing, the workpiece is prone to movement when it is not fixed, which leads to dimensional deviations and a decrease in surface quality, as well as large positioning errors.
A stable clamping structure is adopted, including a base, a clamping seat, a drive cylinder and a limiting component. The drive cylinder drives the pressure block to clamp the workpiece, and the elastic joint restricts the movement of the workpiece, ensuring that the workpiece is stable on the clamping seat.
This achieves stable fixation of the workpiece, reduces cutting force and machine tool vibration, and improves the continuity of the machining process and surface accuracy.

Abstract
Description
[Technical Field]
[0001] This utility model mainly relates to a stable clamping structure. [Background Technology]
[0002] During machining, the workpiece needs to be held in a precise position within the fixture. If not fixed, cutting forces or machine tool vibrations may cause the workpiece to move, resulting in dimensional deviations or a decrease in surface quality. Fixing the workpiece eliminates initial deformation and stress, making the positioning reference for subsequent machining (such as cutting, drilling, etc.) more stable. If machining is performed directly without fixing, positioning errors may occur due to workpiece movement.
[0003] By fixing the workpiece with a clamping device, cutting forces can be balanced, vibration can be reduced, and the continuity of the machining process and surface accuracy can be ensured. In view of this, we have developed a clamping structure for fixing the machined tube. [Utility Model Content]

[0007] The drive cylinder is installed at the lower end of the processing table. The processing table has a through hole for the piston rod of the drive cylinder to pass through. The piston rod is connected to a pressure block. The pressure block is driven by the drive cylinder to connect with the clamping seat so as to press the tube on the clamping seat tightly through the pressure block.
[0008] The clamp is hinged to two sides with limiting members. The limiting members are equipped with elastic connectors, which are inserted into the pipe body to restrict the pipe body within the clamp.
[0009] Preferably, the resilient connector includes a post, a spring, and an abutment block. The end of the post is fixed to a limiting member to rotate with the limiting member. The first end of the post is provided with a groove. One end of the abutment block is hinged to the groove, and the other end of the abutment block is connected to the spring. One end of the spring is fixed to the groove.

[0021] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0022] The preferred embodiment provided by this utility model is as follows: Figures 1-3As shown, a stable clamping structure includes a base 1, a clamping seat 2, and a drive cylinder 3. The base 1 includes a support foot 11 and a processing table 12. The support foot 11 is provided with an opening 13 to facilitate lifting the whole structure. The support foot 11 is located on both sides of the processing table 12. The support foot 11 raises the height of the processing table 12 to facilitate operation and processing. The clamping seat 2 is installed on the processing table 12 and is located on the side of the processing table 12.
[0023] The drive cylinder 3 is installed at the lower end of the processing table 12. The processing table 12 has a through hole 14 for the piston rod of the drive cylinder 3 to pass through. The piston rod is connected to a pressure block 4. The pressure block 4 and the clamping seat 2 are located at the upper end of the processing table 12. The pressure block 4 is driven by the drive cylinder 3 to connect with the clamping seat 2 so as to press the tube body 8 on the clamping seat 2 tightly through the pressure block 4. The processing table 12 is provided with a guide seat 5. The guide seat 5 is vertically provided with a guide post 51. The pressure block 4 is provided with a through hole 14. The through hole 14 is connected to the guide post 51 so that the pressure block 4 slides along the guide post 51.
[0024] The clamp 2 has limiting members 6 hinged to both sides. Each limiting member 6 has an elastic connector 7, which inserts into the pipe body 8 to restrain it within the clamp 2. Both the clamp 2 and the pressure block 4 have corresponding arc-shaped grooves for fitting and placing the pipe body 8. The end of the clamp 2 has a notch 21, which the limiting member 6 is hinged to using a conventional pin connection. The clamp 2 has a clearance at the position of the limiting member 6 to facilitate its rotation.
[0025] The flexible connector 7 includes a plug 71, a spring 72, and an abutment block 73. The end of the plug 71 is fixed to the limiting member 6 so as to rotate with the limiting member 6. The first end of the plug 71 is provided with a groove 74. One end of the abutment block 73 is hinged to the groove 74, and the other end of the abutment block 73 is connected to the spring 72. One end of the spring 72 is fixed to the groove 74, and the abutment block 73 can be moved and pressed against the groove 74 with the cooperation of the spring 72.
[0026] The abutment block 73 is conical, making it easy to insert into pipes of different diameters. The end face of the abutment block 73 is provided with a raised rubber strip 75. The rubber strip 75 is higher than the end face of the abutment block 73, and the rubber strip 75 is used to connect with the pipe body 8 to facilitate the abutment block 73 to fit the connection gap with the pipe body 8. At the same time, the soft rubber strip 75 can also increase the friction.
[0027] Operating procedure: Drive cylinder 3 pushes pressure block 4 upward to open the limiting member 6 at the end of clamp 2, then place tube body 8 on clamp 2, and move pressure block 4 downward to press tube body 8 tightly on clamp 2. At the same time, flip limit member 6 so that the elastic connector 7 of limit member 6 is inserted into the tube opening of tube body 8. The abutment block 73 of elastic connector 7 is an elastic structure that can be adapted to tube openings of different diameters.
