Description

Technical Field

[0001] This utility model belongs to the field of tapping machine technology, specifically relating to a tapping machine with positioning function. Background Technology

[0002] A tapping machine is a type of machining equipment that uses an electric motor to drive a cutting tool connected by gears, belts, etc., and rotates the milling cutter to perform thread processing. The tapping machine's worktable is usually equipped with a fixture for positioning and fixing the workpiece. Under the cutting action of the cutting tool, the workpiece material gradually forms the required threaded hole. There are various types of tapping machines, and the CNC table-type electric tapping machine is one of them. The operator manually places the workpiece on the worktable, where it is positioned and fixed by the fixture. When the tapping machine is started, the spindle cutter taps the positioning points on the workpiece surface.

[0003] Traditional tapping machines use screw-type clamps to hold tools, relying on manual rotation of the screw to tighten and loosen them. For example, when tapping plate-shaped workpieces, it takes multiple turns of the nut to generate sufficient clamping force to fix the workpiece, and the same applies to loosening it. Furthermore, the degree of clamping depends on the operator's manual operation. Stronger employees may clamp too tightly, making screw rotation more difficult, while weaker employees may not clamp tightly enough, causing the workpiece to loosen during processing. When frequent workpiece handling is required, the frequent rotation of the screw is cumbersome and inconvenient, and improvements are needed.

[0004] Existing tapping machines lack a clamping design on the worktable for positioning and fixing the workpiece. To address this, this application proposes a tapping machine with a positioning function. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 5This utility model provides a technical solution: a tapping machine with positioning function, including a tapping machine device, comprising a fixedly connected frame 11 and worktable 12, a column 13 installed on the side of the frame 11, a spindle electrical control box 14 fixedly connected to the top of the column 13, and a tapping spindle 15 with its top end inserted into the spindle electrical control box 14. When the operator starts the tapping machine, the tapping spindle 15 and the tapping tool rotate under the drive of the motor, achieving the purpose of tapping the sheet metal workpiece. The structure and principle of the tapping machine for sheet metal workpieces are existing technologies and will not be described in detail in this application. The positioning component installed on the positioning seat 2 includes a positioning seat 2 fixed to the worktable 12 by screws, a guide arm 3 perpendicular to the positioning seat 2, a support block 6 and a positioning frame 7 connected in combination. The positioning frame 7 plays a positioning role. When the sheet metal workpiece is installed, one side of the sheet metal workpiece is positioned by the positioning frame 7. The guide arm 3 plays a role in limiting the position of the support block 42, so that the support block 42 moves along the guide arm 7. Moving along the length of arm 3, the surface of the positioning frame 7 is provided with equally spaced positioning grooves 71. When the sheet metal workpiece is placed, one side of it is placed in the positioning groove 71. The positioning seat 2 is fixedly connected with symmetrically distributed electromagnets 21. When the electromagnets 21 are charged, the strong permanent magnet electromagnets 21 and the metal magnetic plate 41 are magnetically attracted and firmly held together, thereby keeping the electromagnets 21 in a stable state. The positioning grooves 71 on the inclined surface of the positioning frame 7 are distributed in a stepped manner, which is suitable for limiting the sheet metal at different heights and positions. The clamping assembly includes a metal magnetic plate 41 that is slidably connected to the positioning seat 2, a support block 42 that is fixedly connected to the corner of the metal magnetic plate 41, and a clamping plate 43 that is fixedly connected to the top of the support block 42. A hand screw 5 passes through the center of the metal magnetic plate 41. The clamping plate 43 moves and clamps the sheet metal workpiece. The electromagnets 21 and the metal magnetic plate 41 are fixed together by magnetic attraction. Then, the hand screw 5 is rotated one or two turns to further fix the metal magnetic plate 41 and the positioning seat 2.

[0018] In this embodiment, the positioning frame 7 is a three-dimensional structure of a right triangle, and the positioning grooves 71 are distributed on the inclined surface of the positioning frame 7. The positioning grooves 71 are right triangles in shape, and the positioning grooves 71 on the inclined surface of the positioning frame 7 are distributed in a stepped manner, which is suitable for limiting the plate at different heights and positions.

[0019] In this embodiment, a locking block 72 is welded to the bottom surface of the positioning frame 7 and inserted into the support block 6. A Torx screw 61 for locking the locking block 72 passes through the surface of the support block 6. When the support block 6 and the positioning frame 7 are combined, the locking block 72 is embedded in the support block 6. The Torx screw 61 is manually rotated to fix the locking block 72, thus keeping the positioning frame 7 stable. The positioning frame 7 and the support block 6 are a combined structure, which makes it easy to replace different positioning frames 7. The positioning seat 2 includes a vertical plate and a horizontal plate. The support block 6 and the guide arm 3 are perpendicular to the vertical plate. The electromagnet 21 is located on the horizontal plate. The positioning seat 2 fixes the support block 6 and the guide arm 3.

[0020] In this embodiment, the clamping plate 43 is a right-angle structure, the support block 42 is an isosceles trapezoidal three-dimensional structure, and the support block 42 is provided with a slot b for the guide arm 3 to pass through. The guide arm 3 restricts the support block 42 and prevents the support block 42 from tilting.

[0021] In this embodiment, a support assembly is provided on the positioning seat 2. The support assembly includes a support plate 81 and a support block 82 that are fixedly connected. The support plate 81 has a "U" shaped structure. A concave square groove a is provided on the inner surface of the bottom end of the positioning seat 2. The support plate 81 is adapted to the square groove a. The support plate 81 and the support block 82 play the role of supporting the sheet metal workpiece. The support plate 81 and the positioning seat 2 are a combined structure. The support plate 81 and the support block 82 are detachable so that they can be replaced with support plates 81 and support blocks 82 of different heights to meet the conditions of supporting sheet metal workpieces of different heights.

[0022] Working principle and usage process of this utility model: When fixing the plate workpiece, one side of the plate workpiece is placed in the positioning groove 71. Manually move the clamping plate 43. The clamping plate 43, the support block 42, and the metal magnetic plate 41 move as a whole, so that the clamping plate 43 clamps the plate workpiece. At this time, the electromagnet 21 is in the off state. The guide arm 3 restricts the support block 42 to prevent the support block 42 from tilting; The support plate 81 and the support block 82 support the sheet metal workpiece to prevent the sheet metal workpiece from being deformed during tapping due to the lack of support. The workbench 12 is equipped with a control switch for controlling the electromagnet 21. The principle of the control switch controlling the electromagnet 21 is a conventional technical means, which will not be described in detail in this application. When the electromagnet 21 is in the start-up state, the strong permanent magnet electromagnet 21 and the metal magnetic plate 41 are firmly attracted by magnetic attraction, thereby keeping the electromagnet 21 and the metal magnetic plate 41 in a stable state. At this time, the plate workpiece is fixed. Tighten the hand screw 5 by one or two more turns to further secure the metal magnetic plate 41 and the positioning seat 2. In summary: The tapping machine of this application has a clamping design on the worktable 12 for positioning and fixing the workpiece. This application achieves the positioning and fixing of the plate workpiece through the designed positioning component and clamping component, without the need for frequent rotation of the screw for clamping, tightening and loosening. The plate workpiece is fixed between the positioning frame 7 and the clamping plate 43. When the electromagnet 21 is de-energized, it is easy to change the position of the plate workpiece.

[0023] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
