Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically to a pneumatic quick-change side-top tooling for CNC machining. Background Technology

[0002] The new side-mounted pneumatic quick-change tooling is a modular quick-change terminal designed to address the pain points of "long downtime for fixture changes, unstable lateral positioning, and excessive manual intervention" in CNC multi-variety, small-batch production. Traditional "pull-down" zero-point systems occupy Z-axis space, and lateral reference components such as valve bodies and housings can only be raised twice and manually tightened, resulting in long changeover times. Furthermore, the side-mounted mechanism conflicts with the quick-change disc interface, making "one-click pneumatic interchange" impossible. With the advancement of flexible manufacturing, there is an urgent need for a new type of pneumatic zero-point quick-change side-mounted tooling with ultra-thin side locks, zero Z-axis interference, and compatibility with lateral positioning references to accelerate production line cycle time and improve multi-variety, small-batch production and profitability.

[0003] Patent publication number CN221735245U discloses a quick-clamping welding side-top fixture, including a side-top fixture body. The bottom of the side-top fixture body is provided with a side-top component for limiting and fixing the workpiece. The top of the side-top fixture body is provided with an installation component for convenient replacement of the side-top component. The installation component includes an installation groove that extends through the top of the side-top fixture body. The installation groove has an L-shaped cross-section. An installation plate is provided inside the installation groove. Two spaced positioning blocks are installed on both sides of the installation plate. A positioning groove is provided on the side of the side-top fixture body near the positioning blocks.

[0004] To address the issue of forward and backward displacement of the mounting plate, existing technology employs a nested combination of positioning blocks and positioning slots to prevent such displacement. Furthermore, the use of a limiting bracket and limiting slots restricts the top of the mounting plate, ensuring effective restraint of the aluminum pad. However, this approach still suffers from inaccurate positioning and poor compatibility with quick-change systems, leading to reduced disassembly and replacement efficiency and reduced production revenue.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A pneumatic quick-change side-top tooling for CNC machining includes a pneumatic base mechanism, an interchangeable tooling plate mechanism is provided on the top surface of the pneumatic base mechanism, and positioning side-top mechanisms are provided on both sides of the top surface of the pneumatic base mechanism and on both sides of the interchangeable tooling plate mechanism.

[0008] The positioning side top mechanism includes a support connecting column, which is fixedly connected to the surface of the pneumatic base mechanism, and a double-acting cylinder is fixedly connected to the top surface of the support connecting column.

[0012] A further improvement of the present invention is that the pneumatic base mechanism includes a working base plate, which is fixedly connected to the surface of the supporting connecting column. A two-position five-way solenoid valve is provided on the top surface of the working base plate.

A positioning pull pin hole is opened inside the positioning base plate.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] like Figure 1-6 As shown, this utility model provides a pneumatic quick-change side-top tooling for CNC machining, including a pneumatic base mechanism 1. An interchangeable tooling plate mechanism 2 is provided on the top surface of the pneumatic base mechanism 1. Positioning side-top mechanisms 3 are provided on both sides of the top surface of the pneumatic base mechanism 1 and on both sides of the interchangeable tooling plate mechanism 2. Each positioning side-top mechanism 3 includes a supporting connecting column 31, which is fixedly connected to the surface of the pneumatic base mechanism 1. A double-acting cylinder 37 is fixedly connected to the top surface of the supporting connecting column 31. A piston 32 is movably connected inside the double-acting cylinder 37. A connecting wedge 33 is fixedly connected to the bottom surface of the piston 32. A sliding column 34 is fixedly connected to the surface of the connecting wedge 33. A sliding wedge 35 is slidably connected to the surface of the sliding column 34. A measuring pin mechanism 36 is provided on one side of the sliding wedge 35, and the measuring pin mechanism 36 includes a top pin. The base plate 362 is fixedly connected to one side of the sliding wedge block 35. A steel spring 364 is fixedly connected to the surface of the top pin base plate 362. A top pin top plate 361 is fixedly connected to one side of the steel spring 364. A movable limiting post 363 is fixedly connected to one side of the top pin top plate 361. The movable limiting post 363 is movably connected inside the top pin base plate 362. The pneumatic base mechanism 1 includes a working base plate 11. The working base plate 11 is fixedly connected to the surface of the supporting connecting post 31. A two-position five-way solenoid valve 12 is provided on the top surface of the working base plate 11. A positioning base plate 15 is fixedly connected to the top surface of the working base plate 11 and to one side of the two-position five-way solenoid valve 12. A positioning pull pin hole 14 is opened inside the positioning base plate 15. Friction push plates 13 are fixedly connected to both sides of the top surface of the working base plate 11 and to both sides of the positioning base plate 15.

[0028] In this embodiment, during CNC machining, the two-position five-way solenoid valve 12 and the double-acting cylinder 37 are connected internally through the support connecting column 31. Activating the two-position five-way solenoid valve 12 causes the double-acting cylinder 37 to drive the piston 32 to move up and down, thereby connecting the wedge block 33 and driving the sliding wedge block 35 to move downward. The lower surface of the sliding wedge block 35 is treated with friction, and after it comes into contact with the friction push plate 13, the sliding wedge block 35 moves towards the center through compression. At the same time, the sliding column 34 acts as a connection limiter, the top pin and top plate 361 press against the tooling plate bottom plate 21 from both sides, the steel spring 364 acts as a shock absorber, and the movable limit column 363 acts as a limiter. Positioning is completed to achieve machining, ensuring accurate positioning of the device and ensuring stability during installation.

[0029] Example 2

[0030] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the interchangeable tooling plate mechanism 2 includes a tooling plate base plate 21, which is movably connected to the top surface of the positioning base plate 15. A tooling plate top plate 24 is fixedly connected to the middle of the top surface of the tooling plate base plate 21. A quick-change rivet mechanism 22 is provided on the top surface of the tooling plate base plate 21 and on both sides of the tooling plate top plate 24. A replacement handle 23 is fixedly connected to one side of the tooling plate base plate 21. The quick-change rivet mechanism 22 includes a rivet top plate 221, which is movably connected to the surface of the tooling plate base plate 21. A threaded rotating rod 222 is fixedly connected inside the rivet top plate 221. The threaded rotating rod 222 is threadedly connected to the tooling plate base plate 21. A limit ball 223 is fixedly connected to the bottom surface of the threaded rotating rod 222. The limit ball 223 engages with the positioning rivet hole 14.

[0031] In this embodiment, during initial positioning, the tooling plate base plate 21 is first installed on the surface of the positioning base plate 15, so that the quick-change rivet mechanism 22 is aligned with the positioning rivet hole 14. The rivet top plate 221 is mechanically twisted into the positioning rivet hole 14, so that the limiting ball 223 is squeezed into the three movable balls in the positioning rivet hole 14, thereby achieving the initial positioning of the tooling plate base plate 21. After processing is completed, the quick-change rivet mechanism 22 is twisted out and pulled out by changing the handle 23, ensuring accurate positioning and compatibility between the device and the quick-change system, thereby improving the disassembly and replacement efficiency.

[0032] The working principle of this pneumatic quick-change side-top tooling for CNC machining will be explained in detail below.

[0033] like Figure 1-6As shown, during CNC machining, the tooling base plate 21 is first installed on the surface of the positioning base plate 15, aligning the quick-change rivet mechanism 22 with the positioning rivet hole 14. The rivet top plate 221 is then mechanically twisted into the positioning rivet hole 14, causing the limit ball 223 to be squeezed into the three movable balls in the positioning rivet hole 14, thus achieving the initial positioning of the tooling base plate 21. The two-position five-way solenoid valve 12 and the double-acting cylinder 37 are connected through the support connecting column 31. Activating the two-position five-way solenoid valve 12 causes the double-acting cylinder 37 to drive the piston. 32 moves up and down, thereby connecting wedge 33 and driving sliding wedge 35 to move downward. The lower surface of sliding wedge 35 is treated with friction. After it comes into contact with friction push plate 13, it is squeezed to make sliding wedge 35 move towards the middle. At the same time, sliding column 34 plays a connecting and limiting role. Top pin and top plate 361 press against tooling plate bottom plate 21 from both sides. Steel spring 364 plays a shock absorption role. Movable limit column 363 plays a limiting role. Positioning is completed and processing is realized. After processing is completed, twist out quick-change rivet mechanism 22. Pull out by changing handle 23 to achieve quick replacement.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
