[0001] The utility model relates to the technical field of tapping machines, in particular to a desktop tapping machine which is convenient for accurate positioning. Background Art

[0002] A tapping machine is a machine tool that uses a tap to process internal threads. It is the most widely used internal thread processing machine tool and is suitable for all machinery manufacturing industries, including machinery manufacturing plants, engineering machinery, automobile and motorcycle parts, aircraft engines, locomotives, tobacco machinery, and general machinery. There are many types of tapping machines, and a desktop tapping machine is one of them. When an existing desktop tapping machine is working, the workpiece must first be installed on the tapping machine. Due to the error in position judgment during installation, the workpiece cannot be moved after being installed on the tapping machine, which may cause the tapping machine to fail to accurately tap the predetermined position during tapping, thereby causing a tapping position deviation. Utility Model Content

[0003] In order to overcome the problems existing in the background technology, the utility model provides a desktop tapping machine that is easy to accurately position, so as to solve the technical problem that the existing tapping machine mentioned in the background technology has position errors during installation, resulting in position deviation during tapping. The utility model can flexibly adjust the position of the installed workpiece according to the position of the drill bit during actual tapping, so that the drill bit can accurately tap the predetermined tapping position.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions:

The tapping drill bit 4 is installed at the bottom of the machine head 3; a movable mounting base 5 for fixing a workpiece is installed on the top of the fixed base 1, and threaded fixing holes 51 for fixing the workpiece are evenly arranged on the mounting base 5; the mounting base 5 is laterally slidably installed on a longitudinal moving mechanism 6 installed on the fixed base 1, and the longitudinal moving mechanism 6 is longitudinally movably installed on the fixed base 1.

[0006] Preferably, the longitudinal moving mechanism 6 includes two L-shaped sliders 61, a connecting slide rod 62, and a screw rod 63. The two sliders 61 are respectively slidably installed in the slide grooves 64 set on both sides of the fixed seat 1. The connecting slide rod 62 is provided with two parallel to each other, and the two ends of the connecting slide rod 62 are respectively connected to the side walls of the two sliders 61. The mounting seat 5 is slidably installed on the connecting slide rod 62, and the screw rod 63 is rotatably installed in the slide groove 64 and is threadedly connected to the slider 61.

[0007] Preferably, a transmission rod 65 is rotatably mounted at the front end of the fixing seat 1 and is connected to the ends of the two screw rods 63 via a worm gear transmission.

[0008] Preferably, an adjusting screw 7 is rotatably connected between the two sliding blocks 61 , and the adjusting screw 7 is threadedly connected to the mounting seat 5 .

[0009] Preferably, handles 8 are provided at the ends of the transmission rod 65 and the adjusting screw 7 for easy rotation.

[0010] The beneficial effects of the utility model are as follows: the utility model is installed on the fixed seat through the horizontal and vertical sliding of the mounting seat. When the workpiece is installed on the mounting seat, the position of the workpiece can be adjusted. When tapping, it is convenient to move the workpiece position according to the drill bit position so that the position to be tapped coincides with the tapping drill bit, and the positioning is more accurate, avoiding tapping deviation.

[0013] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate the understanding of technicians.

[0014] like Figure 1-2As shown, the utility model provides a desktop tapping machine that is easy to accurately position, including a fixed seat 1, a support column 2, a machine head 3, and a tapping drill bit 4. The lower end of the support column 2 is mounted on the fixed seat 1, and the upper end is connected to the machine head 3. The tapping drill bit 4 is installed at the bottom of the machine head 3; a movable mounting seat 5 for fixing a workpiece is installed on the top of the fixed seat 1, and threaded fixing holes 51 for fixing the workpiece are evenly arranged on the mounting seat 5; the mounting seat 5 is slidably installed on the longitudinal moving mechanism 6 installed on the fixed seat 1, and the longitudinal moving mechanism 6 is longitudinally installed on the fixed seat 1. The workpiece to be tapped is fixed on the mounting seat 5 by bolts, and the machine head 3 is operated to make the tapping drill bit 4 descend and align with the position to be tapped. When the tapping drill bit 4 deviates from the position to be tapped, the position of the mounting seat 5 is adjusted horizontally and vertically, thereby adjusting the position of the workpiece, so that the tapping position coincides with the tapping drill bit 4, so that the tapping position can be accurately positioned to avoid errors in the tapping position. When multiple positions on a workpiece need to be tapped, the workpiece is moved so that different positions can be tapped, thereby improving the working efficiency of the tapping machine.

[0015] The longitudinal moving mechanism 6 includes two L-shaped sliders 61, a connecting slide bar 62, and a screw rod 63. The two sliders 61 are respectively slidably mounted in the slide grooves 64 provided on both sides of the fixing seat 1. The connecting slide bar 62 is provided with two parallel connecting slide bars, and the two ends of the connecting slide bar 62 are respectively connected to the side walls of the two sliders 61. The mounting seat 5 is slidably mounted on the connecting slide bar 62, and the screw rod 63 is rotatably mounted in the slide groove 64 and is threadedly connected with the slider 61. By rotating the screw rod 63, the slider 61 moves on the screw rod 63, so that the slider 61 drives the workpiece to move longitudinally, and at the same time, the mounting seat 5 can also move laterally on the connecting slide bar 62, so that the workpiece can be moved arbitrarily, which is convenient for adjusting the position of the workpiece so that the position to be tapped coincides with the tapping drill 4.

[0016] The front end of the fixed seat 1 is rotatably mounted with a transmission rod 65 connected to the ends of the two screw rods 63 through a worm gear transmission. The transmission rod 65 can simultaneously drive the two screw rods 63 to rotate, so that the slider 61 drives the workpiece to move longitudinally.

[0017] An adjusting screw 7 is rotatably connected between the two sliders 61, and the adjusting screw 7 is threadedly connected to the mounting seat 5. By rotating the adjusting screw 7, the mounting seat 5 is driven to drive the workpiece to move horizontally, thereby adjusting the horizontal position of the workpiece.

[0018] The ends of the transmission rod 65 and the adjusting screw 7 are provided with a handle 8 for easy rotation. The screw rod 63 and the adjusting screw 7 can be conveniently and labor-savingly rotated by the handle 8, so as to facilitate the adjustment of the position of the workpiece.

[0019] Working process:

[0020] The workpiece to be tapped is fixed on the mounting seat 5 by bolts, and the machine head 3 is operated to make the tapping drill bit 4 drop to align with the position to be tapped. When the tapping drill bit 4 deviates from the position to be tapped, the two screw rods 63 can be driven to rotate through the transmission rod 65, so that the slider 61 drives the workpiece to move longitudinally, and then the adjusting screw 7 is rotated to drive the mounting seat 5 to drive the workpiece to move laterally, thereby adjusting the lateral position of the workpiece, and adjusting the position of the mounting seat 5 laterally and longitudinally, thereby adjusting the position of the workpiece, so that the tapping position coincides with the tapping drill bit 4, so that the tapping position can be accurately positioned to avoid errors in the tapping position. When multiple positions on the workpiece need to be tapped, the position of the workpiece is moved to tap different positions, thereby improving the working efficiency of the tapping machine.
