Abstract
The invention discloses a special-shaped pipe joint locating device so as to locate a work-piece accurately and stably. The special-shaped pipe joint locating device comprises a clamp body which is provided with a working table used for locating the bottom face of the work-piece. The clamp body is in an L shape after being turned over horizontally. The working table is located above the horizontal transverse edge of the clamp body. A transverse rocking rod is arranged above the vertical edge of the clamp body and hinged to a support. The support is connected above the vertical edge of the clamp body in a threaded mode. An upper clamping claw for locating the upper surface of the work-piece is hinged to the middle of the rocking rod. A side clamping claw is hinged to the end of the transverse edge of the clamp body in the side direction. A clamping part of the side clamping claw corresponds to the side direction of the work-piece. A pulling rod is hinged to the free end of the rocking rod and connected with a hole in the side clamping claw in a sliding mode. The portion, penetrating through the side clamping claw, of the pulling rod is provided with a thread and connected with a nut.
Description
Technical field
The present invention relates to a kind of shape tube joint locating device.
Background technology
Chapped pipe, quarter bend, the concept of square tube wedge angle: chapped pipe, quarter bend, the soldering stainless steel square and rectangular pipe that square tube is traditional, produces with a frame turks-head roll Gun Peiji road side rectangle roll usually.Produce main by flat rolling integer, because plain-barreled roll is double-roller type version, there is the problem that roll gap does not wait and bight stress is inconsistent at square and rectangular pipe four angles, cause square and rectangular pipe four angles not sharp not etc., R=1.2t, rectangular tube chi is round radius, and f is wall thickness.Although meet regarding businesses standard, the high-quality requirement of user to product can not be met.New design have employed turks-head roll four rolling integer, because four roll structures that turks-head roll fills are identical, the roll gap at four angles is equal, bight stress is consistent, when roll-force is enough large, bight produces plastic deformation and makes metal filled bight, and the outer surface of pipe defines the intersection between plane and cambered surface.
In the hydraulic system of vehicle, there is a lot of special-shaped tubular workpiece, because its center carpenters square cun requires higher, adopt conventional workpiece machining clamp often can not meet the demands, modal fixture then adopts changes terminal pad on lathe spindle and scroll chuck, again make floral disc, after floral disc is connected with main shaft, then the vehicle clamper designed in addition is contained on floral disc by interference fit and bolted pattern.The shortcoming of the program is: 1, fabrication cycle is long.2, repeatedly dismantle, spindle coupling disc is installed, the dimensional accuracy of main shaft and terminal pad can be reduced, affect the machining accuracy of follow-up conventional shaft-like workpiece.3, because lathe model is different, the interface pattern of main shaft and terminal pad and size can be different, cause the physical dimension of floral disc and pattern also can be different.Therefore, how to overcome the shortcoming that above fixture exists, enhance productivity, this is the special-shaped pipe joint production urgent need to solve the problem of the industry.
Summary of the invention
The invention is intended to provide a kind of shape tube joint locating device, with the positioning workpieces of accurate stable.
Shape tube joint locating device in this programme, comprise clamp body, clamp body is provided with the workbench for positioning workpieces bottom surface, clamp body is the L shape after flip horizontal, workbench is positioned at above the horizontal edge of its level, horizontal rocking bar is provided with above clamp body vertical edge, rocking bar is hinged on bearing, bearing thread connection is above clamp body vertical edge, the middle part of rocking bar is hinged with the upper gripper jaw of positioning workpieces upper surface, side, clamp body horizontal edge end is hinged with side jaw, the side of the corresponding workpiece of clamping part of side jaw, the free end of rocking bar is hinged with pull bar, hole on pull bar and side jaw is slidably connected, pull bar is provided with screw thread through the part of side jaw and is connected with nut.
This fixture can being fixedly clamped simultaneously to shape tube joint in many ways, first place stable for workpiece on the table before work, then fastening nut, the distance of ordering about nut and pull bar hinge is close, side jaw shakes around hinge under driving on the one hand in this process, its clamping part is close to workpiece, realizes the clamping to workpiece side; On the other hand rocking bar also shakes downwards under the driving of pull bar, and upper gripper jaw hinged on rocking bar is close to workpiece, realizes the clamping above to workpiece, simple operation and clamping is stable.And because rocking bar is by being hinged on bearing, bearing thread connection is above clamp body vertical edge, can also by adjusting the screw displacement of bearing and clamp body, to change the position of rocking bar hinge, thus realize the various parameters such as upper gripper jaw clip position, operating pressure, realize device details adjustment more flexibly.
Further, side jaw is hinged on collateral seat, and collateral seat thread connection is in clamp body horizontal edge side.Realize the adjustment of side jaw position of articulating point.
Further, the positioning head of corresponding workpiece side is provided with in the middle part of clamp body vertical edge.To realize the location of this workpiece side, position.
Further, pad is provided with between nut and side jaw.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: the vertical edge 3 of clamp body 1, workbench 2, clamp body, positioning head 4, bearing 5, rocking bar 6, upper gripper jaw 7, pull bar 8, nut 9, side jaw 10, collateral seat 11, workpiece 12.
Embodiment is substantially as shown in Figure 1: this fixture can being fixedly clamped simultaneously to shape tube joint in many ways, workpiece in embodiment is roughly in the L shape of putting upside down, clamp body is the L shape after flip horizontal, clamp body is provided with the workbench for positioning workpieces bottom surface, workbench is positioned at above the horizontal edge of its level, first place stable for workpiece on the table before work, horizontal rocking bar is provided with above clamp body vertical edge, rocking bar is hinged on bearing, bearing thread connection is in clamp body vertical edge top left side, can by adjusting the screw displacement of bearing and clamp body, to change the position of rocking bar hinge.The middle part of rocking bar is hinged with the upper gripper jaw of positioning workpieces upper surface.Upper gripper jaw extends workpiece surface downwards.Be provided with the positioning head of corresponding workpiece side in the middle part of clamp body vertical edge, the afterbody of positioning head embeds in the locating hole on clamp body.
