Description

Technical Field

[0001] The utility model relates to the technical field of tap equipment, in particular to a tap with a torque limiting protection function. Background Art

[0002] A tap is a tool for producing internal threads. Based on shape, it can be categorized as spiral flute taps, angled flute taps, straight flute taps, and pipe thread taps. Based on usage, it can be divided into hand taps and machine taps. Based on specifications, it can be categorized into metric, American, and imperial taps. Taps are the most common tool used by manufacturing operators for threading. Machine and hand taps are the standard taps for cutting common threads. In China, high-speed steel ground taps, manufactured with high precision, are traditionally referred to as machine taps, while rolled (or cut) taps made of carbon tool steel or alloy tool steel are referred to as hand taps. In practice, the two have essentially the same structure and operating principles. A tap typically consists of a working part and a shank. The working part is further divided into a cutting section and a calibrating section. The former, equipped with a cutting cone, performs cutting work, while the latter calibrates the thread size and shape.

[0003] An existing patent publication (publication number CN202137477U) discloses a tap overload protection device comprising a tool holder, a transmission sleeve slidingly sleeved outside the tool holder, the tapered bottom portion of the tool holder extending from the bottom surface of the transmission sleeve; a waist-shaped groove formed in the tool holder, through which a bolt extends to connect the transmission sleeve to the tool holder; a nut sleeve disposed outside the transmission sleeve; a tap chuck mounted within the nut sleeve, below the transmission sleeve, having a square hole in the center of the tap chuck. Adjustment screws are mounted on either side of the upper end of the square hole in the tap chuck, each with a steel ball inside. Compression springs mounted on the adjustment screws press against the steel balls; a plurality of small holes are evenly distributed around the upper surface of the tap chuck; and a plurality of strip-shaped holes are formed at the lower end of the transmission sleeve, facing the small holes. Ball studs supported by compression springs are mounted in each of the strip-shaped holes. This utility model automatically protects the tap from breakage when the tap torque increases, thereby reducing production costs.

[0004] However, there are some problems in the use of existing tap protection devices: 1. The current tap protection devices on the market lack a convenient installation device for the torque limiting protection during use, which makes it difficult to conveniently limit the torque during use, making it more troublesome for personnel to operate and reducing the efficiency of use; 2. The current tap protection devices on the market are difficult to install the entire anti-torque component during operation, making it difficult to conveniently install the anti-torque device, thereby reducing the overall anti-torque protection.

[0009] The anti-torque assembly includes an insert fixedly connected to the bottom of the tap body, one end of the insert is provided with a top cover, the bottom of the top cover is cooperatively connected to a limiter, and the tap body is limited by the limiter.

[0010] As a further solution of the present invention: the position limiting protection assembly further includes a connecting block fixedly connected to one end of the bolt, and a handle is fixedly connected to the surface of the connecting block.

[0011] As a further solution of the present invention: the anti-torque component further includes an embedding groove opened on the surface of the top cover, and an embedding block is fitted and connected inside the embedding groove.

[0012] As a further solution of the present invention: an external thread is provided on the surface of the tap body, an internal thread is provided inside the mounting seat, and the external thread is fitted and connected inside the internal thread.

[0014] As a further solution of the present invention: a limiter is cooperatively connected inside the inner cavity, and the top cover is movably connected inside the mounting seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When the tap body needs to be quickly limited and protected during operation, the user installs the mounting seat on the bottom of the tap body and inserts the bottom of the tap body into the mounting seat. At this time, the handle can be rotated to drive the connecting block fixed at one end to rotate, and the connecting block drives the bolt fixed at one end to rotate. The bolt is cooperatively connected to the inside of the screw hole opened on the surface of the mounting seat. The inside of the screw hole and the inside of the mounting seat are in a through shape, so that the bolt can be inserted into the mounting seat to squeeze and fix the surface of the tap body, thereby providing position limiting protection for it. Then, the tap protection device has a protective device that can be easily installed for its torque limiting protection measure during use, so that it is convenient to perform torque limiting during use, which is relatively simple for personnel to operate and improves the efficiency of use.

[0017] When the tap body of the utility model needs to perform anti-torque work during operation, the tap body is installed inside the mounting seat, and the bottom of the tap body is inserted into the embedding groove provided on the surface of the top cover through a fixedly connected embedding block. The embedding groove and the embedding block are rectangular, and are not easy to slip during connection and rotation. The limiter connected to the bottom of the push rod limits the rotation cycle length of the top cover, so that the rotation of the tap body increases the anti-torque function. The tap body is subjected to anti-torque treatment through the limiter, and the force during its rotation is transmitted and shared. The limiter is installed through the inner cavity provided inside the cylinder, and then the tap protection device is relatively simple to install the overall anti-torque component during operation, which facilitates the convenient installation of the anti-torque device and improves the overall anti-torque protection.
