Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] like Figures 1 to 4As shown, a machine tool control clamping mechanism includes a clamping base 1 for mounting on the machine tool. A placement base plate for placing workpieces is mounted on the clamping base 1. Vertical support sliding frames 2 are mounted on both sides of the top surface of the clamping base 1. A sliding mounting base 3 is movably mounted on the two vertical support sliding frames 2. A movable control structure is connected above the sliding mounting base 3 to drive the sliding mounting base plate to move up and down between the two vertical support sliding frames 2. The workpiece to be processed is placed on the placement base plate of this clamping mechanism. Then, by controlling the up and down movement of the movable control structure, the workpiece placed on the placement base plate is limited and fixed, thus facilitating the machine tool to process the fixed workpiece and preventing the workpiece from moving during processing, which would affect the quality requirements of the processed workpiece.

[0031] In this embodiment, connecting angle steels are respectively connected to both sides of the bottom end of the sliding mounting base plate 3. The ends of the two connecting angle steels away from the sliding mounting base plate are connected to a flexibly deformable limiting clamp 31. The two ends of the limiting clamp 31 are respectively flexibly limited by the vertical support sliding frame 2 on the same side. The flexibly deformable limiting clamp 31 is installed and connected to the bottom end of the sliding mounting base plate 3. By controlling the movable control structure, the sliding mounting base plate 3 is moved towards the workpiece placed on the base plate. The limiting clamp 31 provides "flexible clamping and limiting" of the workpiece, avoiding improper control and causing compression deformation of the workpiece, thereby protecting the workpiece.

[0032] Example 2

[0033] Based on Embodiment 1, the activity control structure of this setting includes a telescopic hydraulic rod 4; the top shell of the telescopic hydraulic rod 4 is connected to a fixed angle steel 41, the fixed angle steel 41 is connected to a top crossbeam 42 by bolts, the top crossbeam 42 is connected to the top of the vertical support sliding frame 2, and the output end of the telescopic hydraulic rod 4 is connected to the sliding mounting base plate 3 through a connecting structure.

[0034] Furthermore, the connection structure includes a connecting top plate 5; movable guide connecting shafts 51 are respectively arranged around the end of the connecting top plate 5 away from the telescopic hydraulic rod 4. One end of the movable guide connecting shaft 51 can movably pass through the connecting top plate 5, and the other end of the movable guide connecting shaft 51 is connected to the sliding mounting base plate 3. At the same time, a deformation spring 52 is respectively sleeved on each movable guide connecting shaft 51. One end of the deformation spring 52 is connected to the sliding mounting base plate 3, and the other end of the deformation spring 52 is connected to the connecting top plate 5. In order to facilitate real-time observation of the "force" of the workpiece clamping and avoid improper control that causes extrusion deformation of the workpiece, pressure gauges are installed and connected to both the sliding mounting base plate 3 and the connecting top plate 5. The pressure gauges are respectively connected to the sliding connecting rod, and the other end of the sliding connecting rod is slidably set to the vertical support sliding frame 2 through a sliding plate. In addition, fixed connecting plates are respectively connected to both ends of the limiting clamping plate 31, and the fixed connecting plates are used to slide and connect with the vertical support sliding frame 2. Vertical sliding guide plates 21 are connected to the fixed connecting plates respectively. The vertical sliding guide plates 21 are slidably set with the vertical support sliding frame 2 via guide rails.

[0035] In this embodiment, by controlling the telescopic hydraulic rod 4 downwards, the connecting top plate 5 and the sliding mounting base plate 3, which is flexibly connected to the connecting top plate 5 via a deformation spring 52, move downwards toward the workpiece placed on the base plate until the limiting clamp 31 contacts the workpiece. Based on design requirements or experience, the downward extension of the telescopic hydraulic rod 4 is adjusted by monitoring the pressure on the pressure gauge, thereby adjusting the tightness of the limiting clamp 31 in securing the workpiece. The flexible structure of the limiting clamp 31, along with the deformation protection of the movable guide shaft 51 and the deformation spring 52, protects the workpiece from excessive force, preventing deformation and ensuring processing quality. This clamping mechanism is not only simple in structure and easy to control, operate, and install / disassemble, but most importantly, it effectively limits and fixes the workpiece, facilitating processing, improving efficiency, and ensuring the quality of the processed workpiece.
