[0002] A coordinate boring machine is a high-precision metal cutting machine tool, mainly used for machining hole systems and contours with precise coordinate positioning requirements.

[0003] Currently, coordinate boring machines have a simple boring platform structure and lack workpiece positioning and clamping functions. They generally require additional auxiliary workpieces for clamping and fixing, which affects clamping efficiency and cannot adapt to workpieces of different heights, thus affecting clamping stability. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a coordinate boring machine with a machining positioning device, which can clamp both sides of the workpiece by the clamping rods that move closer together, and can clamp the other two sides of the workpiece by the clamping blocks that move inward, so as to solve the problem mentioned in the background art.

[0007] As a preferred technical solution, each clamping block is provided with a second connecting groove at the end away from the boring machine platform. The second connecting grooves are arranged laterally opposite each other. Except for the bottom clamping block, the remaining clamping blocks are all equipped with a second connecting block at the end facing the boring machine platform. The second connecting blocks are all inserted into the second connecting groove.

[0008] As a preferred technical solution, each adjusting block is provided with a lead screw hole that runs horizontally through the adjusting block, and each end of the adjusting groove is provided with a mounting hole. Each mounting hole is equipped with a sealed bearing, and each horizontally opposite lead screw hole is threaded with a lead screw. Both ends of the lead screw are installed in the inner ring of the sealed bearing, and one end of the clamping rod is equipped with a motor connected to the lead screw.

[0009] As a preferred technical solution, the drive mechanism includes a fixed frame and an electric push rod. The fixed frame is arranged in an "L" shape. One end of the fixed frame is installed on the side of the boring machine platform, and the other end of the fixed frame is provided with a through hole.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a coordinate boring machine with a machining positioning device according to this utility model includes a boring machine platform 1. The surface of the boring machine platform 1 is provided with multiple longitudinal sliding grooves 2, and multiple sliders 13 are slidably installed in each of the sliding grooves 2. The surface of the boring machine platform 1 is provided with multiple clamping rods 3 laterally, and the horizontally opposite sliders 13 are fixedly connected to the clamping rods 3. A drive mechanism is installed on both sides of the boring machine platform 1 opposite to the opening of the sliding grooves 2. An adjustment groove is provided on the opposite surface of the clamping rods 3, and multiple adjustment blocks 9 are slidably installed in each of the adjustment grooves. Multiple clamping blocks 4 are assembled on the outside of each adjustment block 9.

[0023] In this embodiment, each of the adjusting blocks 9 opposite to the crossbar is provided with a first connecting groove, and the first connecting grooves are all arranged opposite each other. The clamping blocks 4 below are each equipped with a first connecting block 11 at the position opposite to the first connecting groove, and the first connecting block 11 is inserted into the first connecting groove.

[0024] In this embodiment, each clamping block 4 is provided with a second connecting groove 5 at the end away from the boring machine platform 1. The second connecting grooves 5 are arranged laterally opposite each other. Except for the lowest clamping block, the remaining clamping blocks 4 are all equipped with a second connecting block 6 at the end facing the boring machine platform 1. The second connecting blocks 6 are all inserted into the second connecting groove 5.

[0025] When it is necessary to replace or adjust the clamping block 4, the clamping block 4 can be pulled out directly from the connection point of its upper layer (second connecting groove 5) or the adjusting block (first connecting groove), which is easy to operate.

[0026] In this embodiment, each adjusting block 9 is provided with a lead screw hole that passes through the adjusting block 9 laterally. Both ends of the adjusting groove are provided with mounting holes. Sealed bearings are installed in the mounting holes. Lead screws 10 are threadedly connected to the laterally opposite lead screw holes. Both ends of the lead screws 10 are installed in the inner rings of the sealed bearings. A motor 12 connected to the lead screw 10 is installed at one end of the clamping rod 3.

[0027] In this embodiment, the drive mechanism includes a fixed frame 7 and an electric push rod 8. The fixed frame 7 is arranged in an "L" shape. One end of the fixed frame 7 is installed on the side of the boring machine platform 1, and the other end of the fixed frame 7 is provided with a through hole. The electric push rod 8 is installed on the fixed frame 7. The piston rod of the electric push rod 8 passes through the through hole and extends into the slide groove 2 to abut against the slider 13. The piston rod of the electric push rod 8 is provided with a positioning pin 15. The slider 13 is provided with a positioning hole, and the other end of the positioning pin 15 is inserted into the positioning hole.

[0028] When it is necessary to replace the clamping rod 3, the piston rod of the electric push rod 8 can be fully retracted, so that the positioning pin 15 at its end is disengaged from the positioning hole of the slider 13. At this time, the slider 13 together with the fixed clamping rod 3 can be taken out from the side opening of the slide groove 2, which is convenient for maintenance or replacement of clamping rods of different specifications.

[0029] The horizontally opposing electric push rods are all controlled by the same PLC, enabling the sliders on the same side to move synchronously.

[0030] In this embodiment, the cross-sections of slider 13, slide groove 2, adjustment groove and adjustment block 9 are all set in a "T" shape, so that the adjustment block can only move in the adjustment groove and the slider can only move in the slide groove.

[0031] In this embodiment, the clamping rod 3 is provided with multiple grooves 14 on the side facing the boring machine platform 1.

[0032] Working principle:

[0033] When it is necessary to clamp the workpiece, the drive mechanism located on both sides of the boring machine platform 1 starts to work. Specifically, the piston rod of the electric push rod 8 extends and pushes the slider 13 to slide towards the center of the platform in the slide groove 2 that matches its cross-sectional shape (such as "T" shape). To ensure that the position is fixed after being pushed, the positioning pin 15 at the end of the piston rod is inserted into the positioning hole on the slider 13.

[0034] Since the two sets of horizontally opposite sliders 13 are fixedly connected to the two ends of a clamping rod 3, the opposite movement of the sliders directly drives the two clamping rods 3 to move laterally closer together on the boring machine platform 1.

[0035] The two clamping rods 3 come together and eventually contact the workpiece, clamping and fixing the workpiece on both sides, thus achieving longitudinal positioning and clamping of the workpiece.

[0036] After the above is completed, select and assemble the required number of clamping blocks 4 according to the height of the workpiece to be processed. During assembly, the first connecting block 11 at the top of the bottom clamping block 4 is inserted into the first connecting groove at the bottom of the corresponding adjusting block 9 to achieve the first layer connection. If the height needs to be increased, the second connecting block 6 at the bottom of the upper clamping block 4 is inserted into the second connecting groove 5 at the top of the lower clamping block 4. And so on, multiple layers can be stacked. This modular design allows the clamping device to adapt to workpieces of different heights.

[0037] After the motor is started, the lead screw 10 is driven to rotate. Since the lead screw 10 is threadedly engaged with the lead screw hole on the adjusting block 9, and the adjusting block 9 is restricted to sliding linearly within the adjusting groove with a "T" cross section, the rotating lead screw 10 will drive the two opposing sets of adjusting blocks 9 (and the clamping blocks 4 columns mounted on them) to move towards each other along the adjusting groove.

[0038] The two opposing rows of clamping blocks 4 come together to clamp the workpiece from the other two sides, and cooperate with the horizontal clamping rods 3 to complete the all-round stable clamping of the workpiece from all four sides, ensuring machining accuracy.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
