Abstract
Description
Technical Field
[0001] This utility model relates to the field of thread cutting technology, and more specifically, to a device for tapping threaded holes on the surface of a chassis. Background Technology
[0002] The surface screw hole tapping device of the chassis is usually made of metal material. During the tapping process, the chassis needs to be placed on the pad, and the chassis is fixed by the clamping block. The electric slide rail is pulled down to move the tap downward. After the screw hole is positioned, the tap is started to tap the screw hole.
[0003] However, in actual use, during the tapping process, the contact surface between the tap and the screw hole will generate flying debris, which not only pollutes the environment but may also cause some damage to the surface of the chassis or the screw hole. For the safety of the staff, it is often necessary to stop the operation of the screw hole tapping device on the chassis surface during the process of cleaning the flying debris. Cleaning in narrow gaps is not only very difficult, but also requires the disassembly of some parts to clean it thoroughly. Otherwise, the flying debris in the parts may affect the subsequent use of the screw hole tapping device on the chassis surface. Utility Model Content

Vibration machines are fixed on both the front and rear sides of the vibration plate. Multiple vibration springs are fixed on both sides of the vibration plate. Four of the vibration springs are fixed with a sieve plate on their tops, and the other four vibration springs are fixedly connected to the vibration groove.
[0007] A fixed plate is slidably connected to the outside of the sieve plate, and a telescopic tube is provided through the bottom of the sieve plate. A dust collection bag is threadedly connected to one side of the telescopic tube, and a door panel is rotatably connected to one side of the machine casing.
[0008] As a further description of the above technical solution:
[0009] The fixed plate has sliding grooves on both sides, and sliding rods are slidably connected to the inner sides of the two sliding grooves. A sliding plate is fixedly attached to one end of the sliding rod, and a clamping block is fixedly attached to the top of the sliding plate. An arc-shaped groove is opened on the surface of the clamping block. A connecting rod is hinged to the other end of the sliding rod, and a force transmission rod is hinged to one end of the connecting rod.
[0010] As a further description of the above technical solution:
[0011] One end of the force transmission rod is hinged to a rotating plate, a pedal is fixedly provided on one side of the rotating plate, a guide post is hinged to the bottom of the rotating plate, and a sleeve is fixedly provided at the bottom of the guide post.
[0012] As a further description of the above technical solution:
[0013] An adjusting spring is fixedly installed inside the sleeve, the adjusting spring is fixedly connected to the rotating plate, and the sleeve is sleeved with the pedal.
[0014] As a further description of the above technical solution:
[0015] An exhaust plate is provided on one side of the casing, and a fan is fixedly provided on one side of the exhaust plate. A fan column is fixedly connected to the output end of the fan, and multiple fan blades are fixedly provided on the outer side of the fan column.

[0020] The technical effects and advantages of this utility model are as follows:
[0021] 1. By setting up a dust collection mechanism, the self-cleaning ability of the screw hole tapping device is increased compared with the existing technology. When the fan is turned on and the fan blades are turned on, the screen plate vibrates in conjunction with the action of the vibrating plate, which can screen the flying debris that falls on the screen plate during tapping into the dust collection bag. When the operator picks up the machine box by hand, he can step on the pedal with his foot. Through the lever action, the clamping plate is opened to both sides. The arc groove of the clamping block can clamp the machine box with the surface of the arc or cylindrical shape, and the flat part of the clamping block can clamp the square machine box.
[0022] 2. By setting up a bayonet block, a positioning block, and a telescopic rod, compared with the existing technology, during the tapping process of the screw hole, the electric slide rail is activated. As the cover plate moves downward, the positioning block is pulled down, and the telescopic rod is pulled to its maximum length. When it contacts the surface of the chassis, the positioning block is in a horizontal position, and the tap can be opened to tap the screw hole, thereby reducing the problem of tap breakage caused by inaccurate positioning during the tapping process.

[0040] Manually pull down the positioning block 31. The telescopic rod 30, which is fixedly connected between the bayonet block 29 and the positioning block 31, will be extended. When the telescopic rod 30 reaches its maximum length, start the electric slide rail 28 to drive the cover plate 27. The bayonet block 29, telescopic rod 30 and positioning block 31 at the bottom of the cover plate 27 move down at the same time. Only the head of the tap 32 inside the positioning block 31 is exposed. When the positioning block 31 contacts the surface of the chassis and is horizontal, the motor 33 can be started to drive the tap 32 to tap the screw hole. After the tap 32 enters a certain depth, pull the positioning block 31 back up to return to its original position and continue to complete the tapping.
