Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping technology, and in particular to a rapid clamping and positioning platform. Background Technology

[0002] When machining flat workpieces on CNC machine tools, reliable clamping and precise positioning are required. Existing clamping methods mainly include negative pressure adsorption, electromagnet clamping, and specific fixture fixing. However, negative pressure adsorption consumes a lot of energy and carries the risk of workpiece displacement; electromagnet clamping is only suitable for workpieces made of magnetic materials and can also lose magnetism, leading to workpiece displacement; specific fixture methods are generally suitable for workpieces of specific shapes, have poor adaptability, and because they are localized, they can easily cause uneven stress on the workpiece, leading to warping. All of these clamping methods have their own drawbacks, limiting clamping effectiveness and affecting machining accuracy, necessitating technological improvements. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rapid clamping and positioning platform includes a loading table. The upper surface of the loading table is provided with a plurality of arrayed adsorption holes and threaded holes, and each row of adsorption holes and each row of threaded holes are staggered. The adsorption holes are used to adsorb the workpiece onto the loading table by means of negative pressure. The threaded holes are used to install side positioning parts and / or upper pressure parts. The side positioning parts are used to limit the side surface of the workpiece, and the upper pressure parts are used to limit the upper surface of the workpiece.

[0006] As an alternative, the loading platform has several grooves, which are crisscrossed to divide the upper surface of the loading platform into several unit squares. Each unit square is provided with an adsorption hole or a threaded hole. A sealing strip is provided in the groove, and the sealing strip forms a closed area that does not exceed the projected outline of the workpiece.

[0007] As an alternative, the side surface of the loading platform is provided with negative pressure holes, which are connected to a negative pressure pump.

[0009] As an alternative, the side positioning component includes a stop bar and fixing bolts. At least two fixing bolts are provided on the stop bar, and the fixing bolts are threaded into the threaded holes. The side surface of the workpiece abuts against the stop bar.

[0010] As an optional solution, the upper pressure component includes a pressure strip, a pad, and a locking bolt. The pad is located on one side of the workpiece, and the height of the pad is the same as the height of the workpiece. One end of the pressure strip is mounted on the pad, and the other end of the pressure strip presses against the workpiece. A fixing hole is provided in the middle of the pressure strip, and the locking bolt passes through the fixing hole and is threaded into the threaded hole.

[0023] Example 1:

[0024] Please see Figure 1 and Figure 2 As shown, this embodiment provides a rapid clamping and positioning platform, including a loading table 1. The upper surface of the loading table 1 is provided with a plurality of arrayed adsorption holes 2 and threaded holes 3, and each row of adsorption holes 2 and each row of threaded holes 3 are staggered. The adsorption holes 2 are used to adsorb the workpiece 15 onto the loading table 1 by means of negative pressure. The threaded holes 3 are used to install side positioning parts and / or upper pressure parts. The side positioning parts are used to limit the side surface of the workpiece 15, and the upper pressure parts are used to limit the upper surface of the workpiece 15.

[0025] To improve the negative pressure adsorption effect, the loading table 1 is provided with several grooves 4. The grooves 4 are crisscrossed, dividing the upper surface of the loading table 1 into several unit squares 5. Each unit square 5 is provided with an adsorption hole 2 or a threaded hole 3. A sealing strip 6 is provided in the groove 4. The sealing strip 6 forms a closed area 7 that does not exceed the projected outline of the workpiece 15.

[0026] The sealing strip 6 here is preferably an elastic rubber part, and its length can be selected as needed to form a closed area 7 with the largest area according to the projected outline of the workpiece 15, so as to ensure the negative pressure adsorption effect. Figure 2 The lower left area is one way of enclosing the sealing strip 6. In actual use, it can be used to enclose a larger or even irregular closed area 7.

[0027] Optionally, a negative pressure hole 8 is provided on the side surface of the loading platform 1. The negative pressure hole 8 is connected to a negative pressure pump. Several air passages 9 are provided inside the loading platform 1. Each air passage 9 is connected to a row of adsorption holes 2 and to the negative pressure hole 8, thereby providing adsorption power to each adsorption hole 2 through the negative pressure pump.

[0028] In this embodiment, the side positioning component includes a positioning bolt 10, which is threaded into the threaded hole 3. The side surface of the workpiece 15 abuts against the bolt head of the positioning bolt 10. The specific number and arrangement spacing of the positioning bolts 10 are designed according to the actual size and shape of the workpiece 15.

[0029] In this embodiment, the upper pressing component includes a pressing strip 11, a pad 12, and a locking bolt 13. The pad 12 is located on one side of the workpiece 15, and the height of the pad 12 is the same as the height of the workpiece 15. One end of the pressing strip 11 is mounted on the pad 12, and the other end of the pressing strip 11 is pressed against the workpiece 15. A fixing hole 14 is provided in the middle of the pressing strip 11, and the locking bolt 13 passes through the fixing hole 14 and is threaded into the threaded hole 3.

[0030] Furthermore, the fixing hole 14 is an oblong hole, which allows for adjustment of the pressure position and area of ​​the pressure strip 11 on the workpiece 15.

[0031] like Figure 2 As shown, the side positioning component and the upper pressure component are used simultaneously to limit the side surface and the upper surface of the workpiece 15; the side positioning component or the upper pressure component can also be used alone depending on the situation.

[0032] Therefore, by using the adsorption hole 2 and the threaded hole 3, the workpiece 15 is fixed by a combination of negative pressure adsorption and mechanical limiting, which improves the clamping effect, minimizes displacement during processing, ensures processing accuracy, and is simple to operate and suitable for workpieces 15 of various sizes and shapes.

[0033] Example 2:

[0034] This embodiment provides a rapid clamping and positioning platform, including a loading table 1. The upper surface of the loading table 1 is provided with a plurality of arrayed adsorption holes 2 and threaded holes 3, and each row of adsorption holes 2 and each row of threaded holes 3 are staggered. The adsorption holes 2 are used to adsorb the workpiece 15 onto the loading table 1 by means of negative pressure. The threaded holes 3 are used to install side positioning parts and / or upper pressure parts. The side positioning parts are used to limit the side surface of the workpiece 15, and the upper pressure parts are used to limit the upper surface of the workpiece 15.

[0035] Unlike Embodiment 1, the side positioning component here includes a stop bar and fixing bolts. At least two fixing bolts are provided on the stop bar, and the fixing bolts are threaded into the threaded holes 3. The side surface of the workpiece 15 abuts against the stop bar.

[0036] Specifically, the shape of the stop bar is adapted to the shape of the workpiece 15, and the stop bar restricts the movement of the workpiece 15 on the loading table 1.

[0037] Example 3:

[0038] This embodiment provides a rapid clamping and positioning platform, including a loading table 1. The upper surface of the loading table 1 is provided with a plurality of arrayed adsorption holes 2 and threaded holes 3, and each row of adsorption holes 2 and each row of threaded holes 3 are staggered. The adsorption holes 2 are used to adsorb the workpiece 15 onto the loading table 1 by means of negative pressure. The threaded holes 3 are used to install side positioning parts and / or upper pressure parts. The side positioning parts are used to limit the side surface of the workpiece 15, and the upper pressure parts are used to limit the upper surface of the workpiece 15.

[0039] Unlike Embodiment 1, the side surface of the loading platform 1 is provided with multiple negative pressure holes 8, each negative pressure hole 8 is independently connected to a negative pressure pump, and the loading platform 1 is provided with several air passages 9, each air passage 9 is connected to a row of adsorption holes 2 and is connected to a negative pressure hole 8.

[0040] Therefore, the operation or non-operation of a certain column of adsorption holes 2 can be controlled individually, that is, the adsorption force can be formed at a local position on the loading table 1 according to the size and shape of the workpiece 15, thereby reducing energy consumption.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
