Description

Technical field:

[0001] The present application relates to the technical field of tapping auxiliary devices, and in particular to a visual manual tapping device. Background technology:

[0002] Tapping is widely used in machining. Using a certain torque, a tap is screwed into a hole to produce an internal thread, which can then be used with other threaded connectors. The size and type of tap can be selected based on design requirements. Common thread types include metric and imperial.

[0003] When manually tapping, fitters generally rely on experience and feel to determine whether the tapping is in place. If they make a mistake in judgment, it is very easy for the tap to break in the screw hole and be difficult to remove, which increases the difficulty of processing. Some fitters also use a marker to draw lines on the tap, which leaves coarse marks and can only roughly locate the tapping depth, with poor accuracy. Utility model content:

[0004] In order to solve the above technical problems, the utility model provides a visual manual tapping device, the technical solution adopted is:

[0005] A visual manual tapping device, characterized by comprising:

[0006] A tap handle, wherein the tap handle is provided with a tap in a detachable structure;

[0007] The slide is arranged on the lower end surface of the tap handle in a magnetic structure, and the slide is sleeved on the outside of the tap;

[0008] The fixed cylinder is sleeved on the outside of the sliding cylinder, and the fixed cylinder and the sliding cylinder can slide relative to each other along the axial direction;

[0009] A visual window is vertically opened on the side wall of the fixed cylinder;

[0010] The scale plate is vertically arranged on the outer wall of the fixed cylinder on one side of the viewing window.

[0011] Furthermore, the tap handle includes a jaw block, the lower end surface of the jaw block is arranged in a planar structure, and the lower end surface of the jaw block is in contact with the upper end surface of the slide cylinder.

[0012] Furthermore, a groove is provided on the side wall of the upper end of the slide, and a ring magnet is provided in the groove.

[0013] Furthermore, the inner wall of the fixed cylinder and the side wall of the sliding cylinder are matched with each other in a gap structure.

[0014] Furthermore, an arrow pointing to the scale plate is provided on the lower edge of the slide cylinder.

[0015] The beneficial effect of the utility model is that when tapping, the slide cylinder can slide up and down in the fixed cylinder, the arrow on the slide cylinder moves on the scale plate of the fixed cylinder, and the tapping depth can be displayed in real time, and the tapping depth can be accurately positioned.

[0016] At the same time, the lower plane design of the jaw block has a certain positioning function, ensuring the verticality of the tapping direction and the punching surface. Description of the drawings:

[0020] 1. Tap, 2. Tapping handle, 3. Slide cylinder, 4. Fixed cylinder, 5. Viewing window, 6. Ring magnet. Specific implementation method:

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will now be described in further detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the present invention. The specific implementation scheme of the present invention is as follows:

[0022] A visual manual tapping device includes a tap handle 2, which is detachably mounted with a tap 1. A slide 3 is mounted on the lower end surface of the tap handle 2 via a magnetic attraction mechanism. The slide 3 is sleeved onto the outside of the tap 1, and a fixed cylinder 4 is sleeved onto the outside of the slide 3. The fixed cylinder 4 and the slide 3 are capable of relative axial sliding. A visual window 5 is vertically defined on the sidewall of the fixed cylinder 4. A graduated dial is vertically mounted on the outer wall of the fixed cylinder 4 on one side of the visual window 5. An arrow pointing to the graduated dial is disposed on the lower edge of the slide 3. During tapping, the slide 3 slides up and down within the fixed cylinder 4. The arrow on the slide 3 moves along the graduated dial on the fixed cylinder 4, and the tapping depth is displayed in real time, allowing precise positioning of the tapping depth.

[0023] It should be noted that the tap handle 2 includes a jaw block, the lower end face of the jaw block is a planar structure, and the lower end face of the jaw block is in contact with the upper end face of the slide 3, which has a certain positioning function to ensure the verticality of the tapping direction and the punching surface.

[0024] Specifically, a groove is provided on the upper side wall of the slide 3, and a ring magnet 6 is provided in the groove to ensure magnetic connection, thereby controlling the slide 3 and the tap 1 to move up and down synchronously; and it is convenient to disassemble and replace the tap 1.

[0025] It should be explained that the inner wall of the fixed cylinder 4 and the side wall of the sliding cylinder 3 are matched with a gap structure to prevent radial shaking and ensure accuracy.

[0026] Furthermore, for better observation, an arrow pointing to the scale plate is provided on the lower end surface of the slide 3 .

[0027] The working principle and working process of this utility model are as follows:

[0028] When in use, the lower bottom surface of the fixed cylinder 4 is pressed against the drilling surface of the drilled workpiece, the tapping handle 2 clamps the tap 1, and the lower bottom surface of the jaw block of the tapping handle 2 is pressed against the upper plane of the sliding cylinder 3, and the two planes are pressed against each other; the tapping work is performed, and then the sliding cylinder 3 and the tap 1 are controlled to move up and down synchronously, and the arrow on the sliding cylinder 3 slides on the dial on the fixed cylinder 4, which can accurately display the real-time tapping depth, thereby avoiding the problem that the screw cannot be assembled normally due to insufficient tapping depth and the tap 1 is easily broken due to excessive tapping depth.
