[0002] A bolt tapping device is a tool or equipment used for processing internal threads on metal materials. Bolt tapping devices are widely used in the fields of mechanical manufacturing, maintenance, etc., which can improve production efficiency and the quality of thread processing.

[0003] For existing bolt tapping devices, to prevent bolts from rotating and moving up and down along with tapping components such as die stocks during the tapping process, components for positioning the bolts are generally configured. After the tapping process is completed, the positioning components need to be loosened or opened first before the bolts can be unloaded. Such step-by-step operations are rather troublesome and inconvenient, indirectly reducing the tapping efficiency. Summary of the Utility Model

[0004] In view of this, the utility model provides a bolt tapping device to solve the problem that after the tapping process is completed, the positioning components need to be loosened or opened first before the bolts can be unloaded. Such step-by-step operations are rather troublesome and inconvenient, indirectly reducing the tapping efficiency.

[0005] The technical solution proposed by the utility model is as follows: A bolt tapping device specifically includes: a workbench and a bolt. A bolt positioning sleeve is fixedly installed above the top end at the center position of the workbench. A hexagonal positioning hole is opened inside the bolt positioning sleeve, and the nut of the bolt in an inverted state is inserted and installed in the hexagonal positioning hole.

[0006] Two L-shaped insertion rods are symmetrically and slidably installed through the top end part of the circumferential side wall of the bolt positioning sleeve. A driving ring is slidably sleeved on the outer circumference of the bolt positioning sleeve by spring pushing. Two connecting rods are symmetrically and rotatably connected between the driving ring and the tail ends of the two L-shaped insertion rods. The parts of the two L-shaped insertion rods inserted into the hexagonal positioning hole are in abutting contact with the top end of the nut in an inverted state.

[0007] A U-shaped vertical frame is welded to the bottom end of the bottom plate of the bolt positioning sleeve. A blanking push shaft is slidably installed through the U-shaped vertical frame and the bottom plate of the bolt positioning sleeve by spring plate pushing. A hexagonal push plate is welded to the top end of the blanking push shaft. The hexagonal push plate is of the same shape and size as the hexagonal positioning hole and is slidably matched with the hexagonal positioning hole. When the nut is inserted into the hexagonal positioning hole, it abuts against the hexagonal push plate and pushes the hexagonal push plate and the blanking push shaft to slide downward.

[0008] Further,

[0009] An installation disk is welded to the bottom end of the U-shaped vertical frame, and the installation disk is threadedly fastened to the top center position of the workbench.

[0010] Further,

[0011] Two U-shaped support frames are symmetrically welded to the top end of the circumferential side wall of the bolt positioning sleeve, and two L-shaped insertion rods penetrate and slide through the two U-shaped support frames.

[0012] Further,

[0013] A hexagonal vertical support rod is welded in the middle of one long side of the workbench, and a motor is installed on the upper half of the hexagonal vertical support rod through a spring push and sliding, and a mounting bracket is fastened to the bottom of the motor shaft with a thread;

[0014] The mounting frame consists of a circular mounting plate at the top, a mounting ring at the bottom, and three L-shaped support rods welded around the circular mounting plate and the mounting ring.

[0015] Further,

[0016] A die is fixedly mounted on the bottom end of the mounting frame, a positioning ring is welded on the outer circumference of the die, and the positioning ring is threadedly fastened to the mounting ring;

[0017] The die and the bolt positioning sleeve are located on the same central axis in a vertical direction.

[0018] Further,

[0019] The lower half of the hexagonal vertical support rod is slidably mounted with a mounting ring, the cross section of the mounting ring is a U-shaped structure, and the circumferential outer ring portion of the positioning ring is rotationally matched with the mounting ring.

[0020] Further,

[0021] A T-shaped handlebar is threadedly fastened on the motor, and two push switches are symmetrically installed in the middle position of the cross-bracing rod section of the T-shaped handlebar. The two push switches are used to control the start and stop of the motor and respectively control the forward and reverse rotation of the motor.

[0022] The utility model provides a bolt tapping device with the following beneficial effects:

[0023] 1. The nut is inserted into the hexagonal positioning hole. When the unloading push shaft is pushed down by the nut, the unloading push shaft will compress the spring on it. When the tapping process is completed, the two L-shaped rods are slid away from each other. When the processed bolt is loosened, the spring on the unloading push shaft loses the blocking holding force from the L-shaped rod, and can rebound to drive the unloading push shaft and the hexagonal push plate to slide upward and reset, automatically ejecting and unloading the processed bolt from the inside of the bolt positioning sleeve. Compared with the existing technology, it saves the trouble of manually removing and unloading the bolt after pulling out and loosening the two L-shaped rods, helps to simplify the unloading operation steps of the bolt, and indirectly improves the tapping efficiency of the bolt.

[0024] Second, in the tapping process state, through the hexagonal positioning hole, the bolt positioning sleeve can restrict the rotation of the bolt, avoiding the bolt from rotating together with the die, resulting in the die being unable to rotate relative to the bolt and unable to perform normal and effective tapping on the bolt.

Above the top end at the center of the workbench 1, a bolt positioning sleeve 6 is fixedly installed. A hexagonal positioning hole is provided inside the bolt positioning sleeve 6. The nut of the bolt 9 in an inverted state is inserted and installed in the hexagonal positioning hole;

[0047] At the top part of the circumferential side wall of the bolt positioning sleeve 6, two L-shaped insertion rods 602 are symmetrically and slidably installed through. The circumferential outer side of the bolt positioning sleeve 6 is slidably sleeved with a driving ring 603 through a spring push. Between the driving ring 603 and the tail ends of the two L-shaped insertion rods 602, two connecting rods 6021 are symmetrically and rotatably connected. The parts of the two L-shaped insertion rods 602 inserted into the hexagonal positioning hole are in abutting contact with the top end of the nut in an inverted state;

[0048] At the bottom end of the bottom plate of the bolt positioning sleeve 6, a U-shaped vertical frame 604 is welded. Between the U-shaped vertical frame 604 and the bottom plate of the bolt positioning sleeve 6, an unloading push shaft 7 is slidably installed through a spring plate push. At the top end of the unloading push shaft 7, a hexagonal push plate 701 is welded. The hexagonal push plate 701 is of the same shape and size as the hexagonal positioning hole and is slidably matched with the hexagonal positioning hole; When the nut is inserted into the hexagonal positioning hole, it abuts against the hexagonal push plate 701 and pushes the hexagonal push plate 701 and the unloading push shaft 7 to slide downward;

[0049] Preferably

[0050] A hexagonal vertical support rod 101 is welded in the middle of one long side of the workbench 1. The upper half of the hexagonal vertical support rod 101 is slidably mounted with a motor 2 through a spring. The bottom of the motor 2 shaft is threadedly fastened with a mounting bracket 4.

[0051] The mounting frame 4 is composed of a circular mounting plate at the top, a mounting ring at the bottom, and three L-shaped support rods welded around the circular mounting plate and the mounting ring.

[0052] Preferred

[0053] The bottom end of the mounting frame 4 is fixedly mounted with a die 5, and a positioning ring 501 is welded on the outer circumference of the die 5, and the positioning ring 501 is threadedly fastened to the mounting ring;

[0054] The die 5 and the bolt positioning sleeve 6 are located on the same central axis in a vertical direction.

[0055] Preferred

[0056] The lower half of the hexagonal vertical support rod 101 is slidably mounted with a mounting ring 102 . The cross section of the mounting ring 102 is a U-shaped structure. The outer circumference of the positioning ring 501 is rotatably engaged with the mounting ring 102 .

[0057] Preferred

[0058] A T-shaped handle 201 is threadedly fastened to the motor 2. Two push switches 3 are symmetrically installed in the middle of the cross-bracing section of the T-shaped handle 201. The two push switches 3 are used to control the start and stop of the motor 2 and respectively control the forward and reverse rotation of the motor 2.

[0059] The motor 2 is used to drive the mounting frame 4 and the die 5 to rotate forward and backward. When the bolt 9 is tapped, the motor 2 is first controlled to rotate clockwise, and then the spring on the hexagonal vertical support rod 101 is compressed to drive the motor 2 downward to control the forward rotating die 5 to contact the bolt 9 to perform tapping on the bolt 9. After the tapping is completed, the motor 2 is controlled to rotate counterclockwise in the opposite direction. Under the reverse drive of the motor 2, the die 5 and the newly opened thread on the bolt 9 are screwed counterclockwise and driven to slide upward. When the die 5 is driven to slide upward, it drives the motor 2 to move together. When the die 5 slides upward and disengages from the bolt 9, the spring on the hexagonal vertical support rod 101 loses the pulling and holding force from the thread on the bolt 9, and automatically rebounds to drive the motor 2 and the die 5 to slide upward and reset, and the motor 2 and the die 5 are driven to slide downward by the T-shaped handle 201.

[0060] The screw thread 5 is screwed in the screw thread 6, and the screw thread 5 is screwed in the screw thread 6. When the screw thread 5 is screwed in, the screw thread 5 is screwed in the screw thread 6. When the screw thread 5 is screwed in, the screw thread 5 is screwed in the screw thread 6. When the screw thread 5 is screwed in, the screw thread 5 is screwed in the screw thread 6.

[0061] The two L-shaped rods 602, the two connecting rods 6021 and the driving ring 603 are connected together to form a crank slider mechanism. Through this mechanism, the driving ring 603 can be pushed upward to drive the two L-shaped rods 602 to slide away from each other and be removed from the hexagonal positioning hole to loosen the bolt 9. When the driving ring 603 is driven to slide upward, the spring sleeved on the bolt positioning sleeve 6 is compressed. When the driving ring 603 is loosened, the spring on the bolt positioning sleeve 6 rebounds and drives the driving ring 603 to slide downward, and in conjunction with it drives the two L-shaped rods 602 to slide closer to each other, reset and insert them into the hexagonal positioning hole to re-engage the bolt 9.

[0062] The nut is inserted into the hexagonal positioning hole. When the unloading pushing shaft 7 is pushed down by the nut, the unloading pushing shaft 7 will compress the spring on it. When the tapping process is completed, the two L-shaped insertion rods 602 slide away from each other. When the processed bolt 9 is loosened, the spring on the unloading pushing shaft 7 loses the blocking holding force from the L-shaped insertion rod 602, and can rebound to drive the unloading pushing shaft 7 and the hexagonal pushing plate 701 to slide upward and reset, automatically ejecting the processed bolt 9 from the inside of the bolt positioning sleeve 6 to unload. Compared with the existing technology, it eliminates the trouble of manually removing and unloading the bolt 9 after pulling out and loosening the two L-shaped insertion rods 602, which helps to simplify the unloading operation steps of the bolt 9 and indirectly improves the tapping efficiency of the bolt 9.

[0063] Based on the first embodiment, the second embodiment:

[0064] A mounting plate 6041 is welded to the bottom of the U-shaped vertical frame 604 , and the mounting plate 6041 is screwed and fastened to the top center position of the workbench 1 .

[0065] Preferred

[0066] At the top part of the circumferential side wall of the bolt positioning sleeve 6, two U-shaped support frames 601 are symmetrically welded, and two L-shaped insertion rods 602 are correspondingly and slidably fitted through the two U-shaped support frames 601.

[0067] At the bottom ends of the two short side parts of the workbench 1, two rectangular grounding support frames are symmetrically welded. An electrical box 8 is installed on one of the grounding support frames, and a contactor for controlling the forward and reverse rotation of the motor 2 is arranged inside the electrical box;

[0068] For those skilled in the art of installing, designing, debugging, maintaining, and technically transforming equipment automation systems, how to connect the two push buttons 3 and the two contactors, and how to connect the motor 2 and the two contactors belong to the prior art, and there are also mature corresponding solutions on the market. Manufacturers or individuals can use them after simple debugging after purchase, so it will not be elaborated here.

[0069] Working principle: When tapping the bolt 9, first control the motor 2 to rotate clockwise forward, then compress the spring on the hexagonal vertical support rod 101 to drive the motor 2 downward, control the forward-rotating die 5 to abut against the bolt 9 to perform tapping on the bolt 9. After the tapping is completed, control the motor 2 to rotate counterclockwise backward. Under the reverse drive of the motor 2, the die 5 and the newly opened thread on the bolt 9 are screwed together counterclockwise and are pushed to slide upward. When the die 5 slides upward and is separated from the bolt 9, the spring on the hexagonal vertical support rod 101 loses the pulling and holding force from the thread on the bolt 9 and automatically rebounds to drive the motor 2 and the die 5 to slide upward and reset, and drive the motor 2 and the die 5 to slide downward through the T-shaped handle 201;

[0070] After the die 5 slides upward and is separated from the bolt 9, the two L-shaped insertion rods 602 slide away from each other, and the processed bolt 9 is released. At this time, the spring on the unloading push shaft 7 loses the blocking and holding force from the L-shaped insertion rod 602 and can rebound to drive the unloading push shaft 7 and the hexagonal push plate 701 to slide upward and reset, automatically ejecting the processed bolt 9 from the inside of the bolt positioning sleeve 6 for unloading, and thus completing a tapping operation.

[0071] In this article, the following points need to be noted:

[0073] 2. Without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other to obtain new embodiments.

[0074] The above are only the specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
