Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to an adjustable machining base. Background Technology

[0002] In the field of machining, the machining stand is a key component used to fix the shaft-like workpiece to be machined, and its stability and adjustability directly affect machining accuracy and efficiency. In current technology, with the widespread adoption of CNC machine tools and automated production lines, machining equipment is trending towards modularity and flexibility. Traditional fixed machining stands are difficult to adapt to the position parameters of different machine tool models or tool systems, restricting the flexibility and scalability of production lines. Traditional machining stands typically adopt a fixed design, with their height and clamping position determined during installation, making dynamic adjustment impossible according to actual machining needs.

[0003] In summary, there is an urgent need for an adjustable machining stand that is simple in structure, easy to adjust, and highly stable, capable of quickly adapting to different tool positions, workpiece specifications, and equipment models, while ensuring locking reliability and machining accuracy, thereby improving the flexibility and intelligence of machining.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, an adjustable machining base includes a connecting base 1 with an oblong hole 11. A sleeve 2 is movably disposed within the oblong hole 11. The connecting base 1 has an adjusting assembly for adjusting the height of the sleeve 2. The adjusting assembly includes two adjusting blocks 31 and an adjusting rod 32. The adjusting rod 32 has a first end and a second end. The outer periphery of the first and second ends of the adjusting rod 32 has helical portions with opposite helical directions. The connecting base 1 has a sliding cavity 12 communicating with the oblong hole 11. The two adjusting blocks 31 are symmetrically arranged in the sliding cavity 12, and both adjusting blocks 31 are slidably engaged within the sliding cavity 12. The two adjusting blocks 31 are threadedly engaged with the first and second ends of the adjusting rod 32, respectively. The adjustment rod 32 is rotated to drive the two adjusting blocks 31 to move away from each other or towards each other. The upper ends of the adjusting blocks 31 abut against the bottom of the sleeve 2.

[0025] Each of the adjusting blocks 31 is provided with an inclined surface 311 that abuts against the sleeve 2. The two inclined surfaces 311 are set at an included angle, and each inclined surface 311 abuts against the bottom of the sleeve 2.

[0026] The connecting seat 1 is provided with a guide groove 13, which extends along the length of the connecting seat 1. The bottom of the adjusting block 31 is provided with a guide block 312 that cooperates with the guide groove 13.

[0027] The connecting seat 1 is provided with a vertical plate 14, and one end of the adjusting rod 32 is rotatably connected to the vertical plate 14, so that the rotation of the adjusting rod 32 can be smoother. The other end of the adjusting rod 32 is provided with a knob 33. In this application, the knob 33 is provided with several protrusions on its outer periphery, so as to make it easier to rotate the adjusting rod 32.

[0028] A cylinder 41 is installed on the upper end of the connecting seat 1, and a pressure block 42 is installed on the output end of the cylinder 41. The connecting seat 1 is provided with a through hole 15 that connects to the waist-shaped hole 11. The through hole 15 extends along the height direction of the connecting seat 1. The pressure block 42 is slidably disposed in the through hole 15. The sleeve 2 is provided with a clearance hole 23 for the pressure block 42 to enter and exit. Through the abutment and cooperation between the pressure block 42 and the inner wall of the sleeve 2 on the machining shaft, shafts of various sizes can be processed.

[0029] The pressure block 42 is provided with a groove 43. The groove 43 has a trapezoidal or triangular cross section, so it can better abut and cooperate with the shaft to be processed, thereby better fixing the shaft. Preferably, the inner wall of the groove 43 is provided with an elastic pad, which can improve stability when fixing the shaft.

[0030] The sleeve 2 is provided with a connecting plate 21, and the connecting plate 21 is provided with two sliders 22. The connecting seat 1 is provided with two sliding grooves 18 arranged along the height direction of the connecting seat 1. The two sliders 22 respectively cooperate with the two sliding grooves 18 to achieve the guiding function, so that the sleeve 2 can only move along the height direction.

[0031] The connecting seat 1 is provided with an adjustment groove 16 arranged along the height direction of the connecting seat 1. An adjustment plate 51 is slidably arranged in the adjustment groove 16. In this application, there are two adjustment grooves 16. The adjustment plate 51 has two protrusions that cooperate with the adjustment groove 16. The adjustment plate 51 abuts against the connecting plate 21 to limit the upper limit position of the sleeve 2. The adjustment plate 51 is provided with a set bolt 53. The set bolt 53 abuts against the connecting seat 1. The connecting seat 1 is provided with a scale bar 17. The adjustment plate 51 is provided with a pointer 52 that cooperates with the scale bar 17.

[0032] In specific adjustment: by adjusting the height of the adjusting plate 51 and observing the correspondence between the pointer 52 and the scale bar 17, the adjusting plate 51 is adjusted to the required height. Then, by rotating the knob 33, the adjusting rod 32 is rotated, which in turn causes the adjusting block 31 to move along the axis of the adjusting rod 32 towards one side. This, in turn, pushes the sleeve 2 upward along the height direction through the inclined surface 311. When the connecting plate 21 on the sleeve 2 abuts against the adjusting plate 51, the sleeve 2 stops moving, thus adjusting the sleeve 2 to the height required by the user.

[0033] When machining and fixing the machining shaft, the machining shaft is inserted into the sleeve 2, and the cylinder 41 is activated, which in turn drives the pressure block 42 to move downward, so that the pressure block 42 abuts against the machining shaft. The machining shaft is fixed by the cooperation between the pressure block 42 and the inner wall of the sleeve 2.
