Description

Technical Field

[0001] This utility model relates to the field of CNC equipment technology, and in particular to the field of sheet metal CNC drilling and tapping machining centers. Background Technology

[0002] Currently, CNC equipment, especially CNC sheet metal drilling and tapping machining centers, uses the Z-axis of the electric spindle to control the depth of drilling, tapping, and countersinking. However, workpieces, especially sheet metal workpieces, are easily deformed under the force of the electric spindle, resulting in deviations between the drilling, tapping, and countersinking depth and the set value, as well as significant deviations in concentricity, leading to defective drilling, tapping, and countersinking. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing technologies by providing a dual-station electric support mechanism for supporting sheet metal workpieces, preventing deformation of the workpieces under the force of the electric spindle, and meeting the requirements for drilling and tapping holes of varying sizes.

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

[0005] A dual-station electric support mechanism, which has the following features:

[0006] Mounting bracket;

[0007] A servo electric cylinder, mounted on a mounting bracket and having a first push rod that can protrude from the upper end of the mounting bracket;

[0008] The end support module is installed on the mounting bracket and provides two spaced support members. The two support members automatically switch positions to match the first support rod, so that the servo electric cylinder drives the first support rod to extend upward, and then the first support rod lifts the corresponding support member, so that the support member establishes a supporting posture.

[0009] The above solution is further described in that the dual-station electric support mechanism is integrated into the sheet metal CNC drilling and tapping equipment, and the support member is used to support the lower side of the sheet metal workpiece to be processed. When the support member is supporting, it forms an upper and lower relative relationship with the Z-axis electric spindle of the sheet metal CNC drilling and tapping equipment.

[0010] The above solution is further described in that the two support members are installed together on the switching tray, the switching tray is installed on the mounting bracket and supported by a guide mechanism that guides the movement of the switching tray, and the switching tray is driven by a cylinder, so that the switching tray drives the two support members to switch positions.

[0011] The above solution is further described in that the support component includes a support section and a top mold and a second top rod respectively distributed at the upper and lower ends of the support section. The top mold is used to contact and support sheet metal workpieces, while the second top rod is embedded in an oil-free bushing. The oil-free bushing is installed on a switching plate, and the second top rod is used to axially connect with the first top rod.

[0012] The above solution is further described as follows: the guiding mechanism is a pair of parallel and spaced linear guides, the switching plate is fixed on the sliding seat of the linear guides, and two support members are located above the area between the two linear guides, and the two support members are arranged back and forth along the sliding direction of the linear guides.

[0013] A further aspect of the above scheme is that the cylinder is mounted on the mounting bracket and is on the same horizontal plane as the switching tray, and the extension and retraction direction of the cylinder is consistent with the movement direction of the switching tray. The extension and retraction end of the cylinder is connected to the switching tray through a floating connector.

[0014] A further improvement of the above scheme is that the mounting bracket is provided with two protruding limiting blocks, which are respectively located at the front and rear ends of the switching tray in the direction of movement, and the two limiting blocks restrict the movement range of the switching tray.

[0015] A further improvement in the above scheme is that the supporting section of the support member is columnar or conical.

[0016] This invention utilizes a servo electric cylinder for precise control, supporting plates of varying thicknesses and maintaining a stable distance between the plate and the machining tool during processing. This ensures that the drilling, tapping, and countersinking depths match the set values. Furthermore, the automatic switching between two support components accommodates drilling and tapping hole diameters of varying sizes, guaranteeing consistent drilling and tapping tolerances and preventing defective drilling, tapping, and countersinking. The simple and practical structure completely solves the problems of plate deformation and uncontrollable processing depth during drilling and tapping. Particularly in countersinking, it allows for precise control of the countersinking depth, meeting the high-precision processing requirements of drilling and tapping machining centers. Attached Figure Description

[0018] Appendix Figure 2 for Figure 1 A side view of the embodiment. Detailed Implementation

[0019] The following will further explain the concept, specific structure and technical effects of the utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the utility model.

[0020] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0021] See Figure 1 , 2 The diagram shown is a preferred embodiment of the present invention, which relates to a dual-station electric support mechanism. The mechanism includes: a mounting bracket 1, a servo electric cylinder 2, and an end-support module 3. The mounting bracket 1 is used to connect to production equipment and provide installation space. In this embodiment, the mounting bracket 1 is a rectangular frame. The servo electric cylinder 2 is mounted on the mounting bracket 1 and has a first support rod 21 that protrudes from the upper end of the mounting bracket. The first support rod 21 is directly axially connected to the piston rod of the servo electric cylinder 2. The end-support module 3 is mounted on the mounting bracket 1 and provides two spaced-apart support members 31. The two support members 31 automatically switch positions to align with the first support rod 21, so that the servo electric cylinder 2 drives the first support rod 21 to extend upwards, thereby lifting the corresponding support member 31 and establishing a supporting posture for that support member 31. This dual-station electric support mechanism is integrated into the sheet metal CNC drilling and tapping equipment. The support member 31 is used to support the lower side of the sheet metal workpiece to be processed. When the support member 31 is supporting, it forms an upper and lower relative relationship with the Z-axis electric spindle of the sheet metal CNC drilling and tapping equipment. This solves the problem of sheet metal deformation and uncontrollable processing depth during drilling and tapping, ensuring that the drilling, tapping and countersinking depths are consistent with the set values ​​and improving processing accuracy.

[0022] Figure 1 , 2As shown, the two support members 31 are mounted together on the switching tray 32. The switching tray 32 is mounted on the mounting bracket 1 and supported by a guide mechanism that guides the movement of the switching tray. The switching tray 32 is driven by a cylinder 33, causing the switching tray 32 to switch the positions of the two support members 31. The support member 31 includes a support section 311 and a top mold 312 and a second top rod 313 respectively distributed at the upper and lower ends of the support section. The top mold 312 is used to contact and support sheet metal workpieces, and the top mold 312 meets the requirements for matching drilling and tapping processing. The second top rod 313 is embedded in an oil-free bushing 314, which is mounted on the switching tray 32. The oil-free bushing 314 provides positioning and guidance, has a simple structure, and is easy to assemble and implement. The second top rod 313 is used to axially connect with the first top rod 21 so that the first top rod 21 can lift the corresponding support member 31 for support work. In this embodiment, the support section 311 of the support member is columnar or conical, and the outer diameter of the support section 311 is larger than the outer diameter of the top mold 312 and the second support rod 313. The support section 311 increases the structural strength and lifting stability of the support member 31.

[0023] The guiding mechanism consists of a pair of parallel, spaced linear guides 34 mounted on the mounting bracket 1. The switching tray 32 is fixed to the sliding seat of the linear guides 34. Two support members 31 are located above the area between the two linear guides 34, and are arranged back-to-back along the sliding direction of the linear guides 34. This facilitates the switching tray 32 in driving the two support members 31 to alternate positions, resulting in a stable structure and allowing the first support rod 21 to rise and insert into the oil-free bushing 314 to push the second support rod 313. In this embodiment, the mounting bracket 1 also has two protruding limiting blocks 11, which are respectively located at the front and rear ends of the switching tray in the direction of movement, limiting the range of movement of the switching tray.

[0024] Figure 1 As shown, the cylinder 33 is mounted on the mounting bracket 1 and is on the same horizontal plane as the switching tray 32. The extension and retraction direction of the cylinder 33 is consistent with the movement direction of the switching tray. The extension and retraction end of the cylinder 33 is connected to the switching tray 32 through the floating connector 35. The floating connector 35 absorbs deviations such as eccentricity and insufficient parallelism between the switching tray and the cylinder, ensuring that the switching tray 32 moves and changes position smoothly and accurately, ensuring that the first push rod 21 rises and inserts into the oil-free bushing 314 to push the second push rod 313, thereby achieving the goal of supporting processing.

[0025] This invention utilizes a servo electric cylinder for precise control, supporting plates of varying thicknesses and maintaining a stable distance between the plate and the machining tool during processing. This ensures that the drilling, tapping, and countersinking depths match the set values. Furthermore, the automatic switching between two support components accommodates drilling and tapping hole diameters of varying sizes, guaranteeing consistent drilling and tapping tolerances and preventing defective drilling, tapping, and countersinking. The simple and practical structure completely solves the problems of plate deformation and uncontrollable processing depth during drilling and tapping. Particularly in countersinking, it allows for precise control of the countersinking depth, meeting the high-precision processing requirements of drilling and tapping machining centers.

[0026] While the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to the same structure and operation as described above and the accompanying drawings. For those skilled in the art, many equivalent improvements and variations can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and variations should all fall within the scope of protection claimed by the present invention.
