Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, in particular to a drilling device for flange processing. Background Art

[0002] Flange is a mechanical connection element, usually used to connect pipes, valves, pumps and other equipment. It is generally round and consists of flat or raised edges. They can ensure the sealing of the connection point and prevent fluid or gas leakage. The flange can be fixed to the external connection equipment by bolts or nuts. In the production of flanges, it is necessary to drill holes on the surface of the flange so that the flange can be installed with additional accessories or used to connect other equipment and pipelines.

[0003] A Chinese patent with publication number CN217167523U discloses a flange drilling fixture, which drives the fixture base to a suitable position by an electric telescopic rod, pulls a movable clamp, places the flange between two clamp mechanisms, loosens the movable clamp to clamp the flange, and then uses a drilling body to drill the flange. The inventor found that although the device achieves the purpose of clamping and fixing flanges of different specifications, when processing flanges in large quantities, the worker needs to place the flange between the concave groove formed by the movable clamp and the fixture body each time. During this process, it is difficult for the flange to be clamped exactly in the center of the workbench, and it is very easy to be offset. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a drilling device for flange processing, which solves the problem in the prior art that when drilling a large number of flanges, the flanges are in an offset position after being clamped and fixed, which is not conducive to subsequent processing.

[0005] According to an embodiment of the utility model, a drilling device for flange processing includes a base, a guide rail is arranged directly above the base through a support column, a drilling machine is movably arranged on the guide rail, a slider is symmetrically and slidably arranged on the top of the base, and a driving component for driving the two sliders to move toward or away from each other is also provided on the top of the base, a concave block is provided on the top of the two sliders, the grooves of the two concave blocks are arranged opposite to each other, and each concave block is provided with a fixing component for fixing the flange, one of the concave blocks is horizontally penetrated and slidably provided with two tooth plates, and a push plate is provided at the ends of the two tooth plates away from each other, and the concave block is also provided with a centering component for driving the two tooth plates to move simultaneously toward or away from each other.

[0006] Compared with the prior art, the utility model has the following beneficial effects: by using the centering component on one of the concave blocks to drive the push plate to push the flange toward the center of the device, the driving component also drives the concave block to move toward the center of the device, so that the flange is in the center position, the fixing component fixes the flange in the center position, and the drilling machine on the guide rail can drill holes in the fixed flange. Since the two concave blocks and the two push plates can always push the flange to the center, when drilling a large number of flanges, the flange is always in the same position and will not shift. The position of the hole drilled by the drilling machine is fixed each time, which ensures the quality of the flange drilling. Workers do not need to correct the position of the flange every time, which saves labor and improves production efficiency.

[0008] Furthermore, the fixing assembly includes: a hydraulic cylinder, and the top of each concave block is provided with the hydraulic cylinder, and the output end of each hydraulic cylinder extends into the groove of the corresponding concave block and is provided with a clamping plate.

[0009] Furthermore, a non-slip rubber pad is fixedly provided on the bottom of each abutting plate.

DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 As shown in FIG. 4 , an embodiment of the utility model proposes a drilling device for flange processing, comprising a base 1, a guide rail is arranged directly above the base 1 through a support column 2, a drilling machine 3 is movably arranged on the guide rail, a slider 4 is symmetrically and slidably arranged on the top of the base 1, and a driving component for driving the two sliders 4 to move towards or away from each other is also arranged on the top of the base 1, a concave block 5 is arranged on the top of the two sliders 4, the grooves of the two concave blocks 5 are arranged opposite to each other, and each concave block 5 is provided with a fixing component for fixing the flange, one of the concave blocks 5 is horizontally penetrated and slidably provided with two tooth plates 6, and a push plate 7 is provided at the ends of the two tooth plates 6 away from each other, and a centering component for driving the two tooth plates 6 to move towards or away from each other at the same time is also provided on the concave block 5. When in use, first start the driving assembly to drive the two sliders 4 to move a suitable distance in the direction of approaching each other, so that the flange can be stably placed in the grooves of the two concave blocks 5, and then start the centering assembly and the driving assembly. The centering assembly makes the push plates 7 at the ends of the two tooth plates 6 move in the direction of approaching each other, and the driving assembly also drives the concave block 5 to move, so that the flange that was originally eccentric moves toward the center under the push of the push plate 7 until the flange to be drilled is in the center of the two concave blocks 5 and the two push plates 7, thereby completing the centering of the flange, and then start the fixing assembly to fix the flange. At this time, a hole can be opened on the flange by the drilling machine 3, and each subsequent flange is fixed in the center position by this device, which is convenient for subsequent processing procedures. Preferably, by setting corresponding sensors and PLC control programs, the drilling machine 3 can perform fixed route actions with the center of the device as the zero point, complete batch processing of flanges, ensure the quality of holes drilled on each flange, and save labor.

[0021] like Figure 3—4, further, the centering assembly includes: a gear 8, a mounting groove is provided on the concave block 5, the gear 8 is rotatably arranged in the mounting groove, two tooth plates 6 are horizontally and symmetrically arranged on both sides of the gear 8, both tooth plates 6 are meshed with the gear 8, and a first motor 9 for driving the gear 8 to rotate is also provided on the side wall of the concave block 5. When centering the flange, the first motor 9 is started, and the first motor 9 drives the gear 8 to rotate (the teeth of the gear 8 and the tooth plate 6 are omitted in the accompanying drawings), and the gear 8 drives the tooth plates 6 on its upper and lower sides to move in the horizontal direction, that is, the push plates 7 at the ends of the two tooth plates 6 move in the direction of approaching each other, thereby pushing the flange to move toward the center of the device, so as to achieve the purpose of centering the flange.

[0022] like Figure 1 —2, further, the fixing assembly includes: a hydraulic cylinder 10, which is provided on the top of each concave block 5, and a clamping plate 11 is provided after the output end of each hydraulic cylinder 10 extends into the groove of the corresponding concave block 5. Under the push of the two concave blocks 5 and the two push plates 7, after the flange is in the exact center position, the hydraulic cylinder 10 is started, and the hydraulic cylinder 10 pushes the clamping plate 11 downward, so that one end of the flange located in the groove of the concave block 5 is pressed against the inner wall of the groove, completing the fixing of the flange.

[0023] like Figure 1 As shown in FIG. 2, further, each bottom of each clamping plate 11 is fixed with an anti-skid rubber pad 12. If the outer surface of the flange is not cleaned, fine particles will remain, and the clamping plate 11 is prone to loosening when clamping and fixing the flange. The anti-skid rubber pad 12 is used to clamp the flange, thereby increasing the force area of ​​the flange and enabling the flange to be stably clamped and fixed.

[0024] like Figure 1 —2, further, a placement table 13 is provided on the opposite sides of the bottom of the two concave blocks 5. Specifically, a platform protruding outward is provided on the opposite sides of the bottom of the two concave blocks 5. When placing the flange, the worker can place the flange between the two placement tables 13 without just inserting the flange into the grooves of the two concave plates. This can save the worker's energy when placing the flange and improve production efficiency. In this embodiment, the plane where the top of the placement table 13 is located should be flush with the top of the inner wall of the groove of the concave block 5, so that it is convenient to push the flange into the groove of the concave block 5 when the concave blocks 5 are close to each other.

[0025] like Figure 1As shown in FIG. 2 , further, an inclined surface 14 is provided between each placing table 13 and the concave block 5. In this embodiment, the height of the top of the placing table 13 is lower than the horizontal height of the bottom of the inner wall of the groove of the concave block 5, and this part of the height difference is transitioned by the inclined surface 14, so that during processing, the concave block 5 can push the flange into the groove of the concave block 5, and when the drilling machine 3 drills a hole, since there is a distance between the placing table 13 and the flange at this time, the drilling machine 3 will not drill into the placing table 13, thereby avoiding damage to the placing table 13.

[0026] like Figure 1 As shown, further, the driving assembly includes: a bidirectional screw 15 and a second motor 16, the second motor 16 is fixedly arranged on the side wall of the base 1, a slide groove is provided on the top of the base 1, two sliders 4 are slidably arranged in the slide groove, the two ends of the bidirectional screw 15 are respectively threadedly connected with the two sliders 4, and one end of the bidirectional screw 15 is connected with the output end of the second motor 16 after passing through the slide groove. When working, the second motor 16 is started, and the rotation of the second motor 16 drives the bidirectional screw 15 to rotate, so that the sliders 4 threadedly connected at both ends of the bidirectional screw 15 move along the slide groove in a direction close to each other, and finally the inner walls of the grooves of the two concave blocks 5 are abutted against the flange, and then the flange is fixed by the fixing assembly.

[0027] like Figure 1 —3, further, the guide rails include: a transverse guide rail 17 and a longitudinal guide rail 18, there are two longitudinal guide rails 18, the two longitudinal guide rails 18 are parallelly mounted on the top of the support column 2, the transverse guide rail 17 is mounted between the two longitudinal guide rails 18, and the drilling machine 3 is slidably arranged on the transverse guide rail 17. The transverse guide rail 17 is slidably mounted on the two longitudinal guide rails 18, and the drilling machine 3 can slide on the transverse guide rail 17, thereby realizing the arbitrary movement of the drilling machine 3 in the X and Y directions, so that the drilling machine 3 can drill holes at any position of the flange below it. Preferably, the movement of the transverse guide rail 17 on the longitudinal guide rail 18 and the movement of the drilling machine 3 on the transverse guide rail 17 can be controlled by the PLC control circuit, so as to realize the fixing of the drilling position of each flange by the drilling machine 3, so as to achieve the purpose of drilling holes in flanges in batches. It should be noted that the drilling machine 3 has a telescopic function, or the support column 2 and the slider 4 may have a telescopic function (both are prior arts and will not be elaborated here), so that the drilling machine 3 can move downward or the flange can move upward, so that the drilling machine 3 can perform drilling operations on the flange.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
