Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, specifically a clamping and flipping structure for flange production. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts to each other, and is used for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment, such as speed reducer flanges.

[0003] An investigation revealed that a Chinese utility model patent (or invention patent) discloses a flange clamping device and fixture (publication number: CN207155281U), comprising a positioning seat and a pressure plate, as well as a support frame, a drive mechanism, and a positioning component for workpiece positioning. The positioning component is detachably mounted on the positioning seat, and the pressure plate is mounted on the support frame and located above the positioning seat. The drive mechanism is connected to the pressure plate and drives the pressure plate to rotate around the support frame to press the workpiece. The advantages of this utility model are: the drive mechanism drives the pressure plate located above the positioning seat to rotate and open, facilitating the unobstructed placement of the workpiece into the positioning seat; the placement operation is simple and convenient; and the drive mechanism drives the pressure plate to press the workpiece, saving time and effort and improving the efficiency of workpiece positioning and clamping.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantage is that the existing device can only clamp and fix the flange during use. When it is necessary to flip the flange, the flange must first be untied and then manually flipped and fixed to the device. This process wastes a certain amount of production time and reduces the efficiency of flange production.

[0005] Therefore, this utility model provides a clamping and flipping structure for flange production to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides a clamping and flipping structure for flange production, such as Figure 1-5 As shown, it includes a base 1 and a bracket 11 connected to the top of the base 1;

[0035] The bracket 11 is symmetrically rotatably connected to two side shafts 2, and a collar 3 is connected between the two side shafts 2.

[0036] A base plate 31 is slidably connected to the bracket 11. The base plate 31 is used in conjunction with the collar 3 to support the flange workpiece.

[0037] Two opposing clamping plates 4 are slidably arranged inside the collar 3 to form an adjustable clamping space;

[0038] The bracket 11 is provided with a clamping drive mechanism 5, which is used to drive the two clamping plates 4 to move towards each other to clamp the flange workpiece.

[0039] The bracket 11 is also equipped with a flipping drive mechanism 6, which is used to drive the collar 3 and the clamped flange workpiece to flip as a whole through the side shaft 2; the flange workpiece is placed on the base plate 31, and the clamping drive mechanism 5 pushes the clamping plate 4 to slide in the collar 3 until the outer edge of the flange is clamped, thereby clamping and positioning the flange. The flipping drive mechanism 6 drives the collar 3 connected to the side shaft 2 to flip as a whole, and the flange double-sided processing requirement is realized by flipping from 0 to 180°.

[0040] like Figure 3 and Figure 5 As shown, the clamping drive mechanism 5 includes a square rod 51;

[0041] Each of the side shafts 2 has a square rod 51 slidably connected inside. One end of each square rod 51 is connected to the outer wall of the clamping plate 4, and the other end of each square rod 51 is rotatably connected to a side plate 52. Each side plate 52 has a reverse screw 53 threadedly connected inside. The top of the bracket 11 is provided with a power source 54 that drives the reverse screw 53 to rotate. When the power source 54 is activated, it drives the reverse screw 53 to rotate. The reverse screw 53 drives the two side plates to move towards each other. The side plates 52 push the clamping plate 4 to slide inside the collar 3 through the square rods 51 until they clamp the outer edge of the flange, thereby clamping and positioning the flange.

[0042] like Figure 3 As shown, the power source 54 includes a motor;

[0043] A motor is installed on the side wall of the bracket 11. The output end of the motor is sleeved with a first conical tooth 541. The side wall of the first conical tooth 541 is engaged with a second conical tooth 542. The second conical tooth 542 is connected to the outer wall of the reverse lead screw 53. When the motor is started, the reverse lead screw 53 is driven to rotate through the engagement of the first conical tooth 541 and the second conical tooth 542. The reverse lead screw 53 drives the two side plates 52 to move towards each other.

[0044] like Figure 3As shown, two limiting rods 55 are symmetrically connected to the side wall of the bracket 11, and each side plate 52 is slidably connected to the outer wall of the limiting rod 55; by setting the limiting rod 55, the two side plates 52 can be moved towards each other along the limiting rod 55, which plays a limiting role.

[0045] like Figure 1 and Figure 2 As shown, the flipping drive mechanism 6 includes a gear 61;

[0046] Each of the side shafts 2 has a gear 61 connected to its outer wall, and each gear 61 has a rack 62 meshing with its outer wall. An electric push rod is installed at the top of the bracket 11, and the end of the electric push rod is connected to the top of any of the racks 62. The rack 62 is pushed to move linearly by the electric push rod. When the rack 62 moves, it drives the slider 64 to move synchronously inside the slide groove 63, thereby maintaining the stability of the rack 62 during movement. The rack 62 drives the gear 61 to rotate, causing the side shaft 2 to drive the collar 3 to rotate as a whole. The double-sided processing requirement of the flange is achieved by rotating from 0 to 180°.

[0047] like Figure 2 As shown, the bracket 11 has two sets of corresponding sliding grooves 63, and each sliding groove 63 is connected to a slider 64. Each slider 64 is connected to the side wall of the base plate 31, and any set of sliders 64 is connected to the side wall of the rack 62. Since the sliders 64 are linked with the rack 62 and the base plate 31, the base plate 31 moves synchronously with the rack 62, thereby allowing the base plate 31 to adjust the distance between itself and the collar 3 at all times.

[0048] like Figure 1 As shown, an anti-slip pad is provided at the top of the base plate 31; by providing the anti-slip pad, the stability of the flange workpiece can be improved when it is placed.

[0049] Working principle: The flange workpiece is placed on the anti-slip pad of the base plate 31. The motor is started, and the first conical tooth 541 and the second conical tooth 542 mesh to drive the reverse screw 53 to rotate. The reverse screw 53 drives the two side plates 52 to move towards each other along the limiting rod 55. The side plates 52 push the clamping plate 4 to slide in the collar 3 through the square rod 51 until the outer edge of the flange is clamped, thereby clamping and positioning the flange. The electric push rod drives the rack 62 to move linearly. When the rack 62 moves, it drives the slider 64 to move synchronously in the slide groove 63, thereby maintaining the stability of the rack 62 during movement. The rack 62 drives the gear 61 to rotate, causing the side shaft 2 to drive the collar 3 to rotate as a whole. The 0-180° rotation realizes the double-sided processing requirement of the flange. Since the slider 64 is linked with the rack 62 and the base plate 31, it ensures that the base plate 31 moves synchronously with the rack 62, thereby allowing the base plate 31 to adjust the distance between itself and the collar 3 at all times.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
