Description

Technical Field

[0001] The utility model relates to the field of clamping equipment, in particular to a clamping table for fixing a workpiece. Background Art

[0002] Milling machines, grinding machines, drilling machines and other processing equipment generally use a clamping table to fix the workpiece to be processed. In the prior art, the clamping table usually includes a workbench, which is provided with a plurality of T-slots and a clamp that slides and engages with the T-slots. Usually, the clamp only clamps the workpiece in the vertical direction or the horizontal direction, which may cause the workpiece to be forced to move during the processing. The clamp that clamps the workpiece in the vertical direction usually includes a pad, a pressure block located above the pad, and a screw. The workpiece is clamped between the pad and the pressure block, and the screw is used to press the workpiece tightly above the pad. The clamp that clamps the workpiece only in the horizontal direction achieves the fixation of the workpiece by abutting against the edge of the workpiece. For example, the Chinese patent with publication number CN210849972U discloses a T-slot clamp, including a workbench and a T-clamp. The T-clamps are connected by an elastic band, and the elastic band is used to reposition the workpiece. The aforementioned T-slot clamps may have the following issues: 1. The clamp secures the workpiece by interfering with the edge of the workpiece, then wrapping an elastic band around the edge. This means the workpiece may shift during machining due to interference alone. 2. If the workpiece is thin, interfering with the elastic band and clamp results in poor securing.

[0003] In view of this, the present invention proposes a clamping table for fixing a workpiece to solve the above problem. Utility Model Content

An upper seat 23 is connected to the upper side of the lower seat 21 through a connecting mechanism, and a recess 231 for accommodating the edge of the workpiece 3 is provided at the lower end of one side of the upper seat 23, and the inner side of the recess 231 is a vertical plane 232, and the vertical plane 232 is used to contact the edge of the workpiece 3, and the upper seat 23 is provided with a protrusion 233 located above the recess 231, and the protrusion 233 is provided with a fixing screw hole 234 connected to the recess 231, and the fixing screw hole 234 is used to connect a vertical screw 24. The vertical screw 24 is used to press the workpiece 3 tightly against the lower seat 21.

[0025] like Figure 3 As shown, the connection mechanism includes a connecting bolt 25. The upper seat 23 is provided with a first screw hole 236, which vertically extends through the lower seat 21. The lower seat 21 is provided with a second screw hole 211. The connecting bolt 25 is sequentially connected to the first screw hole 236 and the second screw hole 211, thereby connecting the upper seat 23 and the lower seat 21. The distance between the upper seat 23 and the lower seat 21 can be adjusted by the connecting bolt 25, so that the upper seat 23 and the lower seat 21 can clamp workpieces 3 of different thicknesses between them, which is highly practical.

[0026] The connection mechanism also includes a connecting post 26. A through-hole 235 is provided at the center of the upper seat 23 for the connecting post 26 to pass through. The diameter of the through-hole 235 matches the diameter and width of the connecting post 26. A countersunk hole 261 is provided at the center of the connecting post 26, which is connected to the lower seat 21 via a connecting screw 262. The center of the upper seat 23 is connected to the lower seat 21 via the connecting post 26, strengthening the connection between the upper and lower seats 23 and 21, forming a stable support structure that can firmly support and clamp the workpiece 3 during machining, preventing the workpiece 3 from slipping under stress.

[0027] The lower seat 21 is provided with a third screw hole 212 which passes through the lower seat 21 in the vertical direction. The third screw hole 212 passes through the lower seat 21 in the vertical direction. The connecting screw 262 is connected with the countersunk hole 261, the third screw hole 212 and the top of the clamping joint 22 in sequence, so that the connecting column 26, the lower seat 21 and the clamping joint 22 are connected into one.
