State.
The having the beneficial effect that of technique scheme：When tooth machining unit main body tapping is initial, described spring is in compressive state, bullet
Spring passes through wedge and produces a thrust forward and downward elastic force to the end of dental drill, thrust promote dental drill travel forward into
Row tapping, during tapping, the end of dental drill produces counteracting force to wedge, and the propulsion with push rod, instead
Active force is gradually increased, and when the component straight up of counteracting force is more than the elastic force of spring, spring is compressed, wedge
Position moves up, so that wedge departs from dental drill, dental drill stops moving, and leads to tapping work to stop, by pre- to spring
If different decrements, thus controlling dental drill to need the bounce to it for the spring overcoming in tapping, and the acceleration of dental drill
Degree is certain, so when dental drill overcomes the bounce of spring, the depth of institute's tapping is also certain.Using this scheme, energy
Enough depth preferably grasped to workpiece institute tapping.
Prioritization scheme one, as the optimization further to base case, static connection above described slide block has the first expansion link,
Described first expansion link upper end static connection tooth machining unit main body.By the vertical height of the length adjustment dental drill of adjustable telescopic rod, with
Adapt to various sizes of workpiece and carry out tapping work.
Prioritization scheme two, as the optimization further to prioritization scheme one, described tooth machining unit main body includes polished rod axle and brill
Head, described wedge and polished rod axle offset.Wedge promotes tooth machining unit main body gradually close to workpiece, carries out tapping work by drill bit
Make.
Prioritization scheme three, as the optimization further to prioritization scheme two, described clamping fixture table lower end is connected with second and stretches
Bar, described second expansion link is connected in frame.The first expansion link and the length of the second expansion link can be adjusted, thus adjusting tooth
Bore the height with clamping fixture table, dental drill and clamping fixture table alignment, to carry out tapping work, improve the precision of tapping screw thread.
Prioritization scheme four, as the optimization further to prioritization scheme three, also includes piston rod, and described push rod right-hand member leads to
Cross piston rod connection liquid cylinder pressure.By arranging the air pressure size in hydraulic cylinder, push rod is driven to move forward, until push rod gram
Take the bounce to push rod for the spring, spring-compressed, make wedge depart from push rod, lead to push rod to stop tapping, so that
Tapping depth reaches default depth.
Prioritization scheme five, as the optimization further to prioritization scheme four, the side of described clamping fixture table is provided with riser.?
When carrying out tapping work, riser is prevented from iron filings and spills.
Brief description
Fig. 1 is the structural representation of this utility model constant-pressure tooth machining unit.
Specific embodiment
Below by specific embodiment, this utility model is described in further detail：
Reference in Figure of description includes：Frame 1, slide rail 2, slide block 3, the first expansion link 4, dental drill 5, polished rod axle
50th, drill bit 51, wedge 6, spring 7, push rod 8, piston rod 9, hydraulic cylinder 10, the second expansion link 11, clamping fixture table 12, riser
13.
Embodiment is substantially as shown in Figure 1：A kind of constant-pressure tooth machining unit, including frame 1, hydraulic cylinder 10 and dental drill 5, institute
State and above frame 1, be connected with slide rail 2, also include the slide block 3 matching with slide rail 2, the top static connection of described slide block 3 has first to stretch
Contracting bar 4, described first expansion link 4 upper end static connection dental drill 5, described dental drill 5 includes polished rod axle 50 and drill bit 51, described polished rod axle
Wedge 6 is mutually had, the wedge surface of described wedge 6 and polished rod axle 50 offset, described wedge 6 upper end is connected with above 50 one end
Push rod 8, is also included spring 7, is connected by spring 7 between described wedge 6 and push rod 8, described push rod 8 and dental drill 5
All parallel with slide block 3, also include piston rod 9, described push rod 8 right-hand member passes through piston rod 9 connection liquid cylinder pressure 10, described dental drill 5
