Description

Technical Field

[0001] This utility model relates to the field of nut production technology, and in particular to a turning device for nut production. Background Technology

[0002] Nuts are fasteners that are screwed onto bolts or screws to provide a fastening effect. They are a necessary component in all manufacturing machinery. Depending on the material, they are divided into several types, such as carbon steel, stainless steel, and non-ferrous metals. Currently, hexagonal nuts require processing on both sides during production. After one side is processed, they need to be manually flipped, which poses a certain safety hazard.

[0003] For example, a nut production turning device with a clamping structure disclosed in Chinese patent literature (publication number: CN213437644U) can turn the nut over by means of bearings after the first clamping plate and the second clamping plate clamp it, and the turning motor drives the nut to perform multi-face processing. The first clamping plate and the second clamping plate can clamp the nut under the push of the first electric telescopic rod and the second electric telescopic rod, which facilitates the turning of the nut and replaces manual clamping and turning, making the work safer.

[0004] However, when clamping and flipping the nut, the hook needs to be removed manually. Operators may forget to remove the hook due to being busy. If the flipping motor is started without removing the hook, the hook may interfere with other parts of the equipment, causing damage to the equipment. Furthermore, the processing table needs to be pulled away during the clamping and flipping process to avoid obstructing the flipping process. After the flipping is completed, the processing table is pushed under the nut for support. The steps are cumbersome and seriously reduce the efficiency of nut processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the cumbersome process of clamping and flipping hexagonal nuts, which not only easily damages the equipment but also seriously reduces processing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A nut production turning device includes a processing table, the processing table having a clamping mechanism inside, and the clamping mechanism including a bidirectional lead screw, one end of which is rotatably connected to the inner wall of one side of the processing table via a bearing;

[0008] The other end of the bidirectional lead screw passes through and extends to one side of the processing table. A first servo motor is fixedly installed on one side of the processing table. The output shaft of the first servo motor is fixedly connected to the other end of the bidirectional lead screw through a coupling. A stroke groove with symmetrical distribution is opened on the top of the processing table. A threaded block with symmetrical distribution is connected to the external thread of the bidirectional lead screw.

[0009] A flipping mechanism is provided above the processing table.

[0010] Preferably, a movable block is fixedly connected to the upper end of the threaded block, the upper end of the movable block passes through the stroke groove and extends above the processing table, and a rotating rod is rotatably connected to the upper inner wall of the movable block via a bearing.

[0011] Preferably, one end of each of the two rotating rods is fixedly connected to a symmetrically distributed V-shaped clamping block, one of the rotating rods is fixedly connected to a counterweight block, and the other end of the other rotating rod is provided with a rectangular sliding groove.

[0012] Preferably, the flipping mechanism includes a mounting block, the inner wall of which is rotatably connected to a drive rod via a bearing, and one end of the drive rod is fixedly connected to a rectangular slide rod.

[0013] Preferably, one end of the rectangular slide rod is slidably inserted into the inner wall of the rectangular slide groove, the other end of the drive rod is externally fixedly sleeved with a worm gear, and a second servo motor is fixedly installed on one side of the mounting block.

[0014] Preferably, the output shaft of the second servo motor is fixedly mounted with a worm gear via a coupling, and the outer surface of the worm gear meshes with the tooth surface of the worm wheel.

[0015] Preferably, the upper end of the processing table is provided with a mounting hole, a hydraulic cylinder is fixedly installed on the inner wall of the mounting hole, one end of the piston rod of the hydraulic cylinder is fixedly connected to a placement platform, and the lower end of the placement platform is fixedly connected to symmetrically distributed guide rods, one end of the guide rods penetrating and extending into the interior of the processing table.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the clamping mechanism and the flipping mechanism work together to automatically clamp the nut using a V-shaped clamping block driven by a first servo motor and a bidirectional lead screw, avoiding the safety hazards of manual operation. A second servo motor combined with a worm gear transmission enables automatic nut flipping. Furthermore, the placement table and hydraulic cylinder work together to raise and lower as needed during nut processing and flipping.

[0027] Example

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: a nut production turning device, including a processing table 1, a clamping mechanism inside the processing table 1, one end of a bidirectional lead screw 2 is rotatably connected to the inner wall of one side of the processing table 1 through a high-precision deep groove ball bearing to ensure flexible and stable rotation, the other end of the bidirectional lead screw 2 passes through the side of the processing table 1 and is rigidly connected to the output shaft of the first servo motor 21 through a coupling, the first servo motor 21 is fixedly installed on the side of the processing table 1 by bolts to provide power for the rotation of the bidirectional lead screw 2, symmetrical stroke grooves 22 are opened on the top of the processing table 1, and the outside of the bidirectional lead screw 2 is connected to symmetrically distributed threaded blocks 23 through threaded engagement to realize the linear movement of the threaded blocks 23 along the lead screw.

[0029] The upper end of the threaded block 23 is fixed with a movable block 24 by welding or bolting. The upper end of the movable block 24 extends through the stroke groove 22 to the top of the processing table 1. Its upper inner wall is rotatably connected to the rotating rod 25 by bearing, so that the rotating rod 25 can rotate flexibly. The two rotating rods 25 are fixed with symmetrically distributed V-shaped clamping blocks 26 by welding or bolting at opposite ends for clamping nuts.

[0030] One of the rotating rods 25 is externally fixedly connected to a counterweight 27 by welding or keying to ensure its stability and keep the V-shaped clamp 26 horizontal. The other rotating rod 25 has a rectangular groove 28 at its other end to prepare for the connection of the subsequent flipping mechanism.

[0031] A flipping mechanism is set above the processing table 1. The mounting block 3 is fixed to the processing table 1 by bolts or welding. Its inner wall is rotatably connected to the drive rod 31 through bearings. One end of the drive rod 31 is fixedly connected to the rectangular slide rod 32. Welding or key connection is used to ensure the connection strength. One end of the rectangular slide rod 32 is slidably inserted into the inner wall of the rectangular slide groove 28 to realize power transmission and motion conversion.

[0032] The other end of the drive rod 31 is externally connected to the worm gear 33 via a key. The second servo motor 34 is fixedly installed on one side of the mounting block 3 via bolts. Its output shaft is connected to the worm 35 via a coupling. The worm 35 meshes with the tooth surface of the worm gear 33 to realize the transmission of power and the reduction and torque increase.

[0033] The upper end of the processing table 1 has a mounting hole 4. The hydraulic cylinder 41 is fixed to the inner wall of the mounting hole 4 by interference fit or bolts. One end of its piston rod is connected to the placement table 42 by welding or hinge.

[0034] The lower end of the placement platform 42 is fixed with symmetrically distributed guide rods 43 by welding or bolting. One end of the guide rod 43 passes through the interior of the processing table 1 and is connected to the processing table 1 by linear bearings or clearance fit to ensure that the placement platform 42 rises and falls smoothly.

[0035] The working process of this utility model:

[0036] Step 1: Place the nut to be processed on the placement platform 42 supported by the hydraulic cylinder 41. The piston rod of the hydraulic cylinder 41 extends, raising the placement platform 42 to a suitable height to provide stable support for the nut and facilitate subsequent clamping operations. Start the first servo motor 21, whose output shaft drives the bidirectional lead screw 2 to rotate. The threaded block 23, which is threaded to the bidirectional lead screw 2, moves linearly along the lead screw, driving the moving block 24, the rotating rod 25 and the V-shaped clamping block 26 to move. The two V-shaped clamping blocks 26 move towards each other, accurately clamping the diagonal sides of the nut to achieve centered fixation. The counterweight block 27 ensures the horizontal stability of the V-shaped clamping blocks 26 in the initial clamping stage.

[0037] Step two: After the nut is clamped and fixed, the upper part of the nut is processed. When it needs to be flipped, the hydraulic cylinder 41 is activated, the piston rod retracts, and the placement table 42 is lowered to make room for the nut to flip and avoid interference. The second servo motor 34 is activated, and its output shaft drives the worm gear 35 to rotate. Through the meshing transmission with the worm wheel 33, the drive rod 31 and the rectangular slide bar 32 are rotated. The rectangular slide bar 32 slides in the rectangular slide groove 28, driving the rotating rod 25 and the V-shaped clamping block 26 to rotate, so as to realize the nut flipping. After the nut is flipped, the piston rod of the hydraulic cylinder 41 extends again, driving the placement table 42 to rise and reset, supporting the flipped nut so as to carry out subsequent processing steps.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
