Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of the present invention. Guarantee drilling of axiality and attack tooth device, include: the clamping device comprises a clamping device 1, a spring 2, a sleeve 3, a connecting rod 4 and a stop block 5; the clamping device 1 penetrates through the stop block 5, the upper end of the clamping device is connected with the connecting rod 4, and the lower end of the clamping device is detachably provided with a drilling bit or a tapping bit 6;
the spring 2 is sleeved between the clamping device 1 and the stop block 5; the stop block 5 is fixed on the table-board; the lower end of the clamping device 1 is detachably provided with a drilling bit or a tapping bit 6; the spring 2 is sleeved on the clamping device 1; the sleeve 3 is arranged outside the clamping device 1, one end of the connecting rod 4 is connected with the upper end of the clamping device, the other end of the connecting rod is supported on a supporting point 7, and the device is also connected with a control device (not shown) for controlling the high-speed rotation of a drilling bit or a tapping bit. When a part 8 needs to be drilled, the lower end of the clamping device 1 is replaced with a punching drill bit 6 with a proper diameter, one end of the connecting rod 4, which is far away from the drill bit 6, is lifted, according to the lever principle, one end of the connecting rod 4, which is connected with the clamping device 1, drives the clamping device 1 to move downwards in the sleeve 3, and the spring 2 is compressed and deformed under the extrusion of the clamping device 1 and the stop block 5. And starting a switch of the control device, and at the moment, rotating the punching drill 6 at a high speed to drill the part 8. After drilling finishes, closing control device's switch, punch bit 6 down trades, loosen connecting rod 4, then clamping device 1 upwards rises at spring 2's resilience in-process, at this moment, trade tapping bit 6, lift connecting rod 4's the one end of keeping away from tapping bit 6, then clamping device 1 is down motion once more, contact the position of having beaten the hole in part 8 once more until tapping bit 6, under the condition that part 8 position kept motionless, starting switch, at this moment, tapping bit 6 rotates at a high speed, carry out tapping operation to part 8. After tapping, the switch is closed, the connecting rod 4 is loosened, the clamping device 1 is lifted upwards in the rebound process of the spring 2, and the tapping drill bit 6 is detached. As the clamping device 1 moves in the sleeve 3 in the drilling and tapping processes, the coaxiality is ensured, and the coaxiality requirement between the drilled unthreaded hole and the screw hole on the part 8 is ensured, and the operation is convenient and simple.
Specifically, referring to fig. 1, the clamping device 1 is in the shape of a stepped circular shaft and is divided into a first cylindrical section at the upper end and a second cylindrical section at the lower end; the diameter of the first cylindrical section is larger than that of the second cylindrical section; the first cylindrical section and the second cylindrical section are integrally formed; the lower end of the second cylindrical section is provided with a receiving hole 11 with an adjustable inner diameter so as to adapt to punching drill bits and tapping drill bits with different diameter specifications. The first cylindrical section and the second cylindrical section form a step, and the step and the second cylindrical section between the stop 5 are jointly used for accommodating the spring 2.
The block 5 is fixed on the table top and has a through hole 51 in the middle. The through hole 51 is used for the passage of the holding device 1.
It will be appreciated that the outer circumference of the first cylindrical section of the clamping device 1 and the inner circumference of the sleeve 3 are in sliding friction and have a low coefficient of friction with each other. At the same time, the clamping device 1 and the sleeve 3 maintain a coaxial relationship, which is very important to ensure the coaxiality requirement between the unthreaded hole and the screw hole of the part 8.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
