Abstract
本实用新型公开了一种外螺牙加工夹具，包括水平底座以及设于水平底座上的限位架和活动支架，活动支架上设有水平座，水平座上依次设有牙杆固定座、轴承座以及穿设于牙杆固定座和轴承座上的牙杆，牙杆前端固定有牙杆爪，末端设有手柄连杆和手柄，牙杆爪外设有固定套，限位架前方设有位于牙杆爪下面的耐磨板固定座；使用时将工件置于牙杆爪的固定套内，手握手柄转动牙杆使工件被限位架限位，工件被卡紧，不会产生轴向和径向的偏移，这样加工外螺牙时精度大大提高，可保证在精度在±0.01mm以内。
The utility model discloses an external screw thread processing fixture, comprising a horizontal base, a limiting frame and a movable frame arranged on the horizontal base, the movable frame is provided with a horizontal seat, the horizontal seat is provided with a threaded rod fixing seat, a bearing seat and a threaded rod inserted through the threaded rod fixing seat and the bearing seat in sequence, a threaded rod claw is fixed to the front end of the threaded rod, a handle connecting rod and a handle are provided at the end, a fixing sleeve is provided outside the threaded rod claw, and a wear-resistant plate fixing seat located below the threaded rod claw is provided in front of the limiting frame; when in use, a workpiece is placed in the fixing sleeve of the threaded rod claw, the threaded rod is rotated by holding the handle so that the workpiece is limited by the limiting frame, the workpiece is clamped, and no axial and radial deviation occurs, so that the precision of processing external screw threads is greatly improved, and the precision can be guaranteed to be within ±0.01mm.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of external screw teeth clamp for machining.
Background technology
Process thread on workpiece, method and apparatus has multiple, and these devices are divided into external screw teeth processing and internal screw thread processing again, and the machining accuracy of external screw teeth will be lower than internal screw thread usually.Mostly processing to external screw teeth in the prior art is to process manually by the lathe employing, and precision can't guarantee to reach ± 0.01mm, is difficult to satisfy need of industrial production.
The utility model content
The purpose of this utility model provide a kind of guarantee machining accuracy at ± 0.01mm with interior external screw teeth clamp for machining.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of external screw teeth clamp for machining, comprise horizontal base and be located at position-limited rack and travel(l)ing rest on the horizontal base, travel(l)ing rest is provided with horizontal base, be provided with tooth bar holder, bearing block on the horizontal base successively and be arranged in tooth bar on tooth bar holder and the bearing block, tooth bar front end is fixed with tooth bar pawl, end is provided with handle and connecting rod and handle, tooth bar pawl is provided with fixed cover outward, and position-limited rack the place ahead is provided with the wearing plate holder that is positioned at below the tooth bar pawl.
Wherein, be provided with the fulcrum bar between described horizontal base and the travel(l)ing rest.
Wherein, described bearing block is provided with pressing plate, and pressing plate is provided with the pilot pin that is positioned at tooth bar top.
In addition, between described tooth bar holder and the bearing block facing that is placed on the tooth bar is arranged.
The beneficial effects of the utility model are: workpiece is placed in the fixed cover of tooth bar pawl, hold handle rotation tooth bar and make limited of workpiece spacing, workpiece is tightened, and can not produce axially and skew radially, like this processing during external screw teeth precision improve greatly, can guarantee in precision in ± 0.01mm.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to shown in Figure 1, a kind of external screw teeth clamp for machining, comprise horizontal base 1 and be located at position-limited rack 2 and travel(l)ing rest 3 on the horizontal base 1, be provided with fulcrum bar 9 between described horizontal base 1 and the travel(l)ing rest 3, travel(l)ing rest 3 is provided with horizontal base 4, be provided with tooth bar holder 5 on the horizontal base 4 successively, bearing block 6 and be arranged in tooth bar 7 on tooth bar holder 5 and the bearing block 6, between described tooth bar holder 5 and the bearing block 6 facing 75 that is placed on the tooth bar 7 is arranged, tooth bar 7 front ends are fixed with tooth bar pawl 71, end is provided with handle and connecting rod 72 and handle 73, the tooth bar pawl 71 outer fixed covers 74 that are provided with, position-limited rack 2 the place aheads are provided with the wearing plate holder 8 that is positioned at below the tooth bar pawl 71, during use, workpiece is placed in the fixed cover 74 of tooth bar pawl 71, hold handle 73 rotation tooth bars 7 and make limited 2 of workpiece spacing, workpiece is tightened, can not produce axially and skew radially, precision improves greatly when processing external screw teeth like this, can guarantee in precision in ± 0.01mm.
In addition, described bearing block 6 is provided with pressing plate 61, and pressing plate 61 is provided with the pilot pin 62 that is positioned at tooth bar 7 tops, when 7 operations of tooth bar put in place, can press pilot pin 62, and pilot pin 62 bottoms embed in the tooth bar 7, prevent that tooth bar 7 from moving forward and backward.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
