Abstract
The utility model has the goal of providing a nitrogen spring propping device which is an effective propping workpiece and can not cause that pressure marks occur on the workpiece surface because the pressure is overhigh, or a drill gun is broken because the pressure is ultra-low. A nitrogen spring is fixed on a sliding table; a spacing device is fixed on the sliding arm of the sliding table; during the machine tool processing, the workpiece is propped by a drill sleeve seat; during the operation of the drill gun, the sliding arm is moved back because the counterforce is increased; and when the spacing device is touched with the nitrogen spring, the nitrogen spring is pressured to generate the counterforce, and thereby, the sliding arm is prevented from moving back. Nitrogen is filled in the nitrogen spring and the pressure is constant, so overhigh pressure or ultra-low pressure does not exist; when appropriate pressure is preset, the pressure marks can not occur on the surface of the workpiece, or the drill gun is not broken. The pressure of the nitrogen spring is constant, so the utility model avoids that pressure marks occur on the workpiece surface because the pressure is overhigh, or a drill gun is broken because the pressure is ultra-low, and enhances the processing efficiency of machine tools.
Description
Technical field
The utility model relates to the holding device on a kind of lathe, especially a kind of nitrogen spring holding device.
Background technology
In the cutting or boring procedure of workpiece; workpiece to be processed need be clamped on lathe in advance; with the drill bushing seat workpiece is withstood then; drill gun stretches out from the drill bushing seat to be processed workpiece; here the function of drill bushing seat is to determine the position and the top tight workpiece of boring; can guarantee simultaneously that drill gun has the support protection, is difficult for departing from or fractureing when rotating at a high speed.In order to guarantee crudy and working depth, require drill bushing seat top tight workpiece all the time, if having the gap between drill bushing seat and the workpiece, also can cause drill gun in the process that rotation is advanced at a high speed, to fracture.Existing way is with both sides drill bushing seat workpiece to be held out against, and both sides drill bushing seat is adjusted the drill bushing seat with and bore position big or small according to workpiece and put along with cursor slide horizontally slips.After slidably the drill bushing seat holds out against workpiece, installing a hydraulic motor holding device again additional holds out against the drill bushing seat, just start lathe then and carry out manufacturing procedure, after processing a hole, drill bushing seat and drill gun are return, workpiece rotates to predeterminated position, and drill bushing seat top tight workpiece once more carries out next one boring processing.But because the reaction speed of hydraulic pressure is more blunt, sometimes can be excessive because of hydraulic coupling, it is too tight to cause the drill bushing seat to contact with the surface of workpiece, causes the surface of workpiece impression to occur, has had a strong impact on the surface quality of workpiece; Sometimes hydraulic coupling is too small, causes having the gap between drill bushing seat and the workpiece, causes drill gun to fracture in the process that rotation is advanced at a high speed.And the frequent flexible hydraulic cylinder of hydraulic motor that causes easily damages.Because the hole that workpiece need be processed is very many, the frequent hydraulic pressure problem of holding out against has had a strong impact on machine tooling efficient and part quality, and fractureing of drill gun also increased sizable a part of cost for enterprise.
Summary of the invention
The purpose of this utility model be to provide a kind of effectively hold out against the drill bushing seat and can not cause owing to pressure is excessive make surface of the work impression or the too small nitrogen spring holding device that drill gun is fractureed of pressure occur.
The utility model is achieved in that a kind of nitrogen spring holding device, comprise the left and right sides slide unit on the bed piece, slide unit is provided with the cursor slide of relative slide unit move left and right, described slide unit is provided with drill gun, the drill bushing seat of described drill gun and the setting of cursor slide front end is complementary, and it is characterized in that: also comprise nitrogen spring that is arranged on the slide unit top and the stopping means that is arranged on the cursor slide top.
But settle the left slide unit and the right slide unit of move left and right on the bed piece, slide unit is provided with the cursor slide of slide unit move left and right relatively, and a drill bushing seat is carried in the place ahead of cursor slide; Left and right sides slide unit provides power to move to the centre by motor, after the drill bushing seat in cursor slide the place ahead holds out against workpiece, is arranged on and stretches out contact workpiece the drill bushing seat of drill gun from cursor slide on the slide unit and start working.Nitrogen spring is fixed on the slide unit, and stopping means is fixed on the cursor slide of slide unit, during machine tooling, and drill bushing seat top tight workpiece, drill gun advances under motor-driven, carries out deep hole machining; Along with the continuous increase of working depth, cursor slide retreats because of reaction force increases, and when the stopping means on the cursor slide is run into nitrogen spring on the slide unit, thereby nitrogen spring can stop retreating of cursor slide because produce active force by compression.Nitrogen spring is commercial, it is constant being full of nitrogen pressure in it, can there be excessive or too small problem, as long as (it is fixed to be come by what of inflated with nitrogen in advance preset pressure, with KPA is unit) suitable, just can not make surface of the work impression occur or add the man-hour drill gun to fracture, and nitrogen spring appraise and decide flexible number of times more than 100,000 times, be several times as much as the scalable number of times of traditional hydraulic motor.The purpose of nitrogen spring is to make drill bushing seat top tight workpiece all the time.
Based on the utility model of above-mentioned design because the pressure of nitrogen spring is constant, so it also is constant that the drill bushing seat imposes on the pressure of workpiece, thereby avoided making surface of the work impression or the too small situation that drill gun is fractureed of pressure occur owing to pressure is excessive, greatly guaranteed product quality and reduced, increased the working (machining) efficiency of lathe because drill gun fractures, hydraulic motor damages the cost allowance that brings.

The specific embodiment
As shown in Figure 1, bed piece (1) but go up to settle move left and right about two slide units (2), slide unit (2) is provided with the cursor slide of slide unit move left and right (3) relatively, the place ahead lift-launch drill bushing seat (4) of cursor slide (3); Left and right sides slide unit (2) provides power to move to the centre by motor, after the drill bushing seat (4) in cursor slide (3) the place ahead holds out against workpiece (6), is arranged on and stretches out top tight workpiece (6) the drill bushing seat (4) of drill gun (5) from cursor slide (3) on the slide unit (3) and start working.As shown in Figure 2, nitrogen spring (7) is fixed on the slide unit (2), and stopping means (8) is fixed on the cursor slide (3) of slide unit, during machine tooling, and drill bushing seat (4) top tight workpiece (6), drill gun (5) advances under motor-driven, carries out deep hole machining; Continuous increase along with working depth, cursor slide (3) retreats because of reaction force increases, when the stopping means (8) on the cursor slide (3) is run into nitrogen spring (7) on the slide unit (2), nitrogen spring (7) thus can be because the active force compression stops retreating of cursor slide (3).Nitrogen spring is full of nitrogen in (7), and its pressure is constant.
