Description

Technical Field

[0001] The utility model relates to a self-locking tap, in particular to a self-locking tap with an anti-slip chuck, belonging to the technical field of taps. Background Art

[0002] A self-locking tap is a specially designed threading tool, primarily characterized by its anti-loosening and anti-vibration properties. During the cutting process, the reaction force from tightening causes the thread profile to distort, creating a reverse-locking, special-shaped structure that prevents loosening and resists vibration. This design gives self-locking taps unique advantages in threading.

[0003] In the prior art, a tap disclosed in Publication No. CN210023999U includes a taper body, one end of which is provided with a spiral cutting edge for machining internal threads on a workpiece. The taper body also includes a chip removal groove along its axial direction. The taper seat also includes a connecting block at one end for connecting to a power shaft. An insert block is provided at the end of the taper body away from the spiral cutting edge. The end of the taper seat away from the connecting block includes a slot extending along its length. The insert block is removably inserted into the slot and is equipped with a locking mechanism for locking it to the taper seat. This allows for easy replacement of the taper body, and the taper body and taper seat are securely connected, preventing them from falling during machining.

[0004] Although the above technical solution can easily replace the vertebral body part and the combination state of the vertebral body and the cone seat is relatively stable, which can prevent it from falling during the processing process, it is unable to guide and limit the tap when feeding the tap, resulting in the tap being offset during movement, which in turn causes defects in the processed workpiece. In view of this, a self-locking tap with an anti-slip chuck is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model provides a self-locking tap with an anti-slip chuck to solve the problem that the tap cannot be guided and limited when it is fed, resulting in deviation of the tap during movement and further causing defects in the processed workpiece.

[0007] The guide mechanism includes a guide member, which is placed on the outer wall of the tap handle. A fixed bearing sleeved on the tap handle is fixed to the inner surface of the guide member. A slider is fixed to the inner wall of the fixed bearing. One side of the slider is slidably connected to a slide groove provided on the tap handle. Two fixed rods are fixed to the side wall of the guide member, and fixed rings are fixed to the ends of the two fixed rods.

[0008] As a further solution of the present invention, four fixing screws are installed inside the fixing ring, and the fixing ring is rotatably connected to the tap handle.

[0009] As a further solution of the present invention: a flow cavity is provided inside the tap handle, and a water outlet hole communicating with the flow cavity is provided at one end of the tap body.

[0011] As a further solution of the present invention: a clamping groove is provided on the inner wall of the tap handle, and a clamping block fixedly connected to the tap body is plugged into the interior of the clamping groove.

[0012] As a further solution of the present invention: a limiting hole is provided on the outer wall of the clamping block.

[0013] As a further solution of the present invention: the internal thread of the limiting hole is connected with a fixing bolt, and the fixing bolt is threadedly connected to the tap handle.

[0014] The beneficial effects of the utility model are as follows: the sliding groove provided on the tap handle and the sliding block provided on the fixed bearing can play a guiding and limiting role, thereby preventing the tap handle from deviating during feeding; the fixing rod provided on the guide member can ensure the stability of the mechanism; the fixed bearing can ensure that the guide member will not rotate when the tap handle rotates; by unscrewing the fixing bolt on the tap handle, the fixing bolt and the limiting hole are separated, and with the cooperation of the clamping groove and the clamping block, the tap body can be easily disassembled and replaced.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0021] like Figures 1 to 4 As shown, a self-locking tap with an anti-slip chuck includes a tap handle 1, one end of the tap handle 1 is connected to a tap body 2, the other end of the tap handle 1 is fixed with an anti-slip disc 3, and the outer wall of the tap handle 1 is installed with a guide mechanism for guiding the tap;

[0022] The guide mechanism includes a guide member 4, which is placed on the outer wall of the tap handle 1. The inner surface of the guide member 4 is fixed with a fixed bearing 41 sleeved on the tap handle 1. The inner wall of the fixed bearing 41 is fixed with a slider 42. One side of the slider 42 is slidably connected to a slide groove 43 provided on the tap handle 1. Two fixed rods 44 are fixed to the side wall of the guide member 4. The ends of the two fixed rods 44 are fixed with a fixed ring 45. Four fixing screws 46 are installed inside the fixing ring 45. The fixing ring 45 is rotatably connected to the tap handle 1. A flow chamber 5 is provided inside the tap handle 1, and a water outlet 6 is provided at one end of the tap body 2 and is interconnected with the flow chamber 5. When the tap handle 1 is fed, it passes through the slide groove 43 provided on the tap handle 1. Since a slider 42 is provided on the fixed bearing 41, it can play a guiding and limiting role, thereby reducing the deviation of the tap handle 1 during feeding. The fixed rod 44 provided on the guide member 4 can ensure the stability of the mechanism. The fixed bearing 41 can ensure that the guide member 4 will not rotate when the tap handle 1 rotates. Example 2

[0023] In addition to all the technical features of the first embodiment, this embodiment further includes: one side of the water outlet 6 is connected to a flow groove 7, the inner wall of the tap handle 1 is provided with a clamping groove 8, the inside of the clamping groove 8 is plugged and connected with a clamping block 9 fixedly connected to the tap body 2, the outer wall of the clamping block 9 is provided with a limiting hole 10, the internal thread of the limiting hole 10 is connected with a fixing bolt 11, and the fixing bolt 11 is threadedly connected to the tap handle 1. External water can enter the water outlet 6 through the flow cavity 5 in the tap handle 1 and then be discharged through the flow groove 7 to cool the tap. When the tap handle 1 needs to be disassembled, the fixing bolt 11 on the tap handle 1 can be unscrewed to separate the fixing bolt 11 and the limiting hole 10. With the cooperation of the clamping groove 8 and the clamping block 9, the tap body 2 can be conveniently disassembled and replaced.

[0024] Working principle: Before using the self-locking tap with anti-slip chuck, first use the anti-slip disc 3 provided on the tap handle 1 to fix the anti-slip disc 3 and the output shaft of the driving device to clamp the tap and reduce the possibility of the tap slipping. Then connect the fixing ring 45 to the housing of the driving device and fix the fixing ring 45 with the fixing screw 46. When in use, the external device drives the tap body 2 to rotate, thereby processing the workpiece, and the external water source can enter the water outlet 6 through the flow cavity 5 in the tap handle 1, and then be discharged through the flow groove 7 to cool the tap, and the tap handle When the tap handle 1 is fed, the sliding groove 43 provided on the tap handle 1 and the slider 42 provided on the fixed bearing 41 can play a guiding and limiting role, thereby reducing the deviation of the tap handle 1 during feeding. The fixing rod 44 provided on the guide member 4 can ensure the stability of the mechanism. The fixed bearing 41 can ensure that the guide member 4 will not rotate when the tap handle 1 rotates. When the tap handle 1 needs to be disassembled, the fixing bolt 11 on the tap handle 1 can be unscrewed to separate the fixing bolt 11 and the limiting hole 10. With the cooperation of the clamping groove 8 and the clamping block 9, the tap body 2 can be easily disassembled and replaced.
