Both the clamping plate and bolts protrude above the workpiece, and the upper surface of the workpiece is covered by the clamping plate. This design obstructs the cutting tool, making it impossible to machine the upper surface of the workpiece. To completely machine the upper surface, the entire clamping plate must be removed after stopping the machine and repositioned. This process easily causes workpiece displacement and deformation, significantly impacting machining accuracy, and multiple stops for repositioning wastes time. Utility Model Content

[0030] 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 embodiments shown in the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0031] Figures 1 to 7 The multifunctional pressure plate shown includes a base 1, a pressure block 3, and a clamping bolt 2, used for mounting on a machining equipment workbench to clamp workpieces. The workbench surface has several parallel inverted T-shaped guide grooves, and the base is fixed to the workbench by T-bolts 4 and matching nuts.
[0032] The pressure block is mounted on top of the base, and a guide structure is provided between the pressure block and the base to guide the pressure block to slide tilted on the base. Figure 4 (in the direction of the arrow), and the pressure block is also fixed to the base by clamping bolts, so that the front end of the pressure block ( Figure 4 The pressure block (on its left side) applies horizontal and vertical downward pressure to the workpiece, clamping and fixing it in place. The front end of the pressure block has a textured surface 35 to increase friction and enhance the clamping force on the workpiece.
[0033] The guide structure includes a slide groove 11 and a lower sliding surface 14 on the top surface of the base, a slide rail 33 and an upper sliding surface 34 on the bottom surface of the pressure block.
[0034] like Figure 5and Figure 8 As shown, the slide groove 11 is located in the middle of the left and right sides of the top surface of the base and runs through the front and rear ends of the base (to...). Figure 8 (The left and right directions are front and back, and the direction perpendicular to the drawing is left and right). The lower sliding surface is located on the left and right sides of the slide groove. The base is provided with vertically extending screw holes 12 and through holes 13. The screw holes penetrate the slide groove and the bottom surface of the base, and the through holes penetrate the lower mounting surface and the bottom surface of the base. The screw holes are used to connect clamping bolts, and the through holes are used to install fasteners to fix it to the worktable. Figure 8 As shown, the bottom surface of the front half of the chute is inclined with the front lower than the back and has the screw holes. The bottom surface of the rear half of the chute is a horizontally arranged lower mounting surface 15 and has the through holes.
[0035] like Figure 3 and Figure 7 As shown, the pressure block has an upper mounting surface 32 and a vertically extending adjusting groove 31. The upper mounting surface is located at the top of the pressure block and is horizontally arranged. The adjusting groove is used to install clamping bolts and extends through the upper mounting surface and the bottom surface of the pressure block. The adjusting groove extends along the front-rear direction of the pressure block (within the longitudinal direction of the pressure block). Figure 7 The left and right directions are front and back (and the direction perpendicular to the drawing is left and right). The bottom surface of the pressure block is provided with an upper sliding surface 34, which can slide and engage with the lower sliding surface; the bottom surface of the pressure block is provided with a slide rail 33 that runs through the front and rear ends of the pressure block. The slide rail is located in the middle of the left and right sides of the upper sliding surface and protrudes downward, so that it can slide and engage with the slide groove.
[0036] Preferably, the upper sliding surface, the lower sliding surface, the bottom surface of the slide rail, and the bottom surface of the first half of the slide groove are all parallel to each other, and the angle formed by these planes and the horizontal plane is 20 degrees to 45 degrees, preferably 30 degrees.
[0037] The pressure block is slidably positioned on the base, with the upper sliding surface and the lower sliding surface forming a sliding pair. The cooperation between the slide rail and the slide groove is used for sliding guidance. At the same time, the projection plane of the adjusting groove and the screw hole in the vertical direction coincides. When the pressure block slides, the screw hole is always located below the adjusting groove to ensure that the clamping bolt can pass through the adjusting groove and engage with the clamping screw hole.
[0038] The base is connected to the workbench as follows: a T-bolt passes from bottom to top through the inverted T-shaped guide groove of the workbench and the through hole of the base, and then engages with a matching nut. The matching nut presses against the lower mounting surface of the base. The matching nut and the T-bolt extending out of the through hole are located above the lower mounting surface and will not interfere with the sliding of the pressure block.
[0039] The connection between the base and the pressure block is as follows: the clamping bolt passes through the adjustment groove of the pressure block from top to bottom and engages with the screw hole of the base, and the clamping bolt presses against the upper mounting surface of the pressure block.
[0040] The working principle of this utility model is as follows:
[0041] 1. According to the shape of the workpiece, the corresponding number of multifunctional machining pressing plates are selected to clamp the workpiece, and the bases of the pressing plates are fixed on the workbench by T-shaped bolts respectively; as shown in the figure, the workpiece is a cuboid, so four pressing plates are arranged around the workpiece; Figure 1
[0042] 2. The sliding rail of the pressing block is embedded with the sliding groove of the base, and the adjusting groove of the pressing block is aligned with the screw hole of the base up and down, and the pressing bolt is screwed to fix the pressing block on the base;
[0043] 3. The pressing bolt of each pressing plate is tightened, the guiding structure decomposes the pressure of the pressing bolt into horizontal pressure pushing towards the workpiece and vertical downward pressure, and the workpiece is stably clamped on the workbench with the cooperation of the surrounding pressing plates;
[0044] 4. The cutter of the machine tool processes the workpiece according to the designed route.
[0045] The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms, and is not limited to the embodiments described in the specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.
