Technical Field

[0001] The utility model belongs to the technical field of flange processing, and particularly relates to a clamping mechanism of a flange processing drill press. Background Art

[0002] The flange processing drill press is mainly used for flange hole opening operations. During the processing of the flange processing drill press, a clamping structure is used to fix the flange. The clamping structure usually consists of two semi-circular bases and a liftable pressing plate. The base serves as the accommodation area for the flange. During processing, the pressing plate presses the flange against the base, and the drill bit of the drill press passes through the preset shaft hole on the pressing plate and then processes the flange located between the base and the pressing plate.

[0003] In the prior art, this structure relies on manual loading and unloading during operation. Especially during the unloading process, since the pressing plate tightly presses the flange against the base during processing, it may be difficult to demold and unload the flange manually because the flange is too closely combined with the base, which affects production efficiency, and the stuck structure is prone to causing personal injuries during operation. Summary of the Utility Model

[0031] An embodiment of the present utility model provides a clamping mechanism for a flange processing drill press, as Figures 1-6 shown, the clamping mechanism of the flange processing drill press includes:

[0032] The pressing plate assembly 300, the pressing plate assembly 300 includes a pressing plate 310 and a lifting rod 320, one end of the lifting rod 320 is connected to the bottom table 100 of the drilling machine, and the other end is connected to the pressing plate 310;

[0033] The supporting module 400, the supporting module 400 includes a first supporting seat 410, a second supporting seat 420 and a jacking assembly 430; The flange is placed in the accommodation area provided between the first supporting seat 410 and the second supporting seat 420. After the drilling machine finishes processing, the jacking assembly 430 rises synchronously with the pressing plate 310 to push the flange out of the accommodation area;

[0034] In the present application, the first supporting seat 410 is cut with an arc-shaped groove on a cuboid structure, and a supporting plate 411 is further provided on the groove. The supporting plate 411 is an arc-shaped structure. The first supporting seat 410 and the second supporting seat 420 have the same structure, are symmetrically arranged, and form a circular accommodation area between the first supporting seat 410 and the second supporting seat 420 for placing the flange. The supporting plate 411 supports the end face of the flange, and the groove abuts against the outer wall of the flange;

[0035] During the processing, the flange will be placed on the supporting plate 411. Due to the symmetrical arrangement of the first supporting seat 410 and the second supporting seat 420, the side walls of the flange respectively abut against the inner walls of the first supporting seat 410 and the second supporting seat 420. The arc-shaped groove and the supporting plate 411 here have the same structure as those in the prior art; The pressing plate 310 will be pressed by the lifting rod 320 on the end face of the flange away from the supporting plate 411 before processing to ensure that the processed and drilled flange will not shift; The bearing table 210 and the drill head 220 of the drilling machine are arranged near the clamping mechanism of the flange processing drilling machine. The drill head 220 adopts a multi-axis drill bit structure and drills a qualified shaft hole on the end face of the flange through the preset shaft hole on the pressing plate 310 during processing;

[0036] A guiding hole is opened on the supporting plate 411, and the drill bit of the drilling machine can extend into the supporting plate 411 at the end of the flange processing to avoid the situation that the drill bit cannot completely penetrate the flange;

[0037] The first supporting seat 410 and the second supporting seat 420 are further provided with sliding grooves 412, and the jacking assembly 430 extends from one end of the first supporting seat 410 to one end of the second supporting seat 420 through the sliding grooves 412; The jacking assembly 430 has no connection relationship with the bottom table 100, the first supporting seat 410 and the second supporting seat 420. The jacking assembly 430 rises with the pressing plate assembly 300 during the rising stage of the pressing plate assembly 300. The jacking assembly 430 ejects the flange in the accommodation area out of the accommodation area during the rising process; The demolding work of the flange is realized through the follow-up function of the jacking assembly 430, reducing the manual operation links and improving the work efficiency;

[0038] As a preferred implementation manner in this embodiment, the jacking assembly 430 includes a connecting plate 431, a connecting block 432, and a jacking rod 433;

[0039] The connecting plate 431 sequentially passes through the first support base 410 and the second support base 420 through the sliding groove 412; the connecting blocks 432 are respectively arranged at both ends of the connecting plate 431, one group of connecting blocks 432 is located outside the first support base 410 away from the second support base 420, and the other group of connecting blocks 432 is located outside the second support base away from the first support base 410;

[0040] The jacking rod 433 is arranged on the connecting plate 431, and a jacking hole for the jacking rod 433 to pass through is arranged on the support plate 411. When the jacking assembly 430 rises synchronously with the pressing plate 310 assembly, the jacking rod 433 passes through the jacking hole to push the flange away from the accommodating area;

[0041] It should be noted that when the connecting plate 431 is in contact connection with the base 100, a part of the structure of the jacking rod 433 is received in the jacking hole. The jacking rod 433 serves as a limit guiding assembly while ensuring the jacking function, ensuring the linearity of the movement;

[0042] As a preferred implementation manner in this embodiment, the pressing plate 310 includes: a plate body 311, a shaft hole 312, and an electromagnet suction block 313; both ends of the plate body 311 are connected to the lifting rod 320, the shaft holes 312 are annularly and arrayedly distributed on the plate body 311, and the electromagnet suction block 313 is arranged on the end face of the plate body 311 facing the support module 400;

[0043] The position of the electromagnet suction block 313 corresponds to the position of the connecting block 432. When the plate body 311 is pressed against the end faces of the first support base 410 and the second support base 420, the electromagnet suction block 313 abuts against the connecting block 432; when the pressing plate 310 is in the lifting stage, that is, when it is away from the support module 400, the electromagnet suction block 313 is energized to generate a magnetic force, and the connecting block 432 in contact connection with the electromagnet suction block 313 will rise synchronously under the action of the magnetic force;

[0044] When the pressing plate 310 is lifted to the highest point, the electromagnet suction block 313 still retains magnetism for a period of time, waits for the flange to be taken away and then demagnetizes. When the magnetism disappears, the jacking assembly 430 falls back onto the base 100 again; the operator reinserts a new flange blank for subsequent processing; the demagnetization time point of the electromagnet suction block 313 is set by timing or by setting an infrared induction method;

[0045] As a preferred implementation mode in this embodiment, the connecting plate 431 is made of a non-metallic material, and the connecting block 432 is made of an iron material that can be magnetically adsorbed; this avoids the connecting plate 431 having magnetism and being blocked during movement in the sliding groove 412;

[0046] It should be noted that for the foregoing embodiments, for the sake of simple description, they are all expressed as a series of action combinations. However, those skilled in the art should know that the present invention is not limited by the described action sequence, because according to the present invention, certain steps may be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.
