Description

A kind of workpiece machining clamp of fast aligning
Technical field
The invention belongs to field of machining, be specially a kind of workpiece machining clamp of fast aligning.
Background technology
In aviation hydraulic system, 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, realize fast aligning work piece processing center on lathe, and be connected on lathe soon by conventional connected mode, thus enhance productivity, this is the special-shaped pipe joint production urgent need to solve the problem of the industry.
Summary of the invention
The object of the invention is: the workpiece machining clamp that a kind of fast aligning of highly versatile is provided.
In order to achieve the above object, the technical scheme adopted is:
A kind of workpiece machining clamp of fast aligning, it is provided with the jig main body containing clamping part, top board working end and grooved guide pad that one connects, described working end is provided with the lock-screw be threaded, and lock-screw lower end embeds V-type plate, and V-type plate is provided with marks closely screw for stuck lock-screw; Described jig main body lower end is provided with the location-plate of being locked by hold-down screw, and described location-plate is provided with alignment pin.
Jig main body material is Cr12MoV, and heat treatment reaches 56-60HRC.
V-type plate and location-plate material are 45# steel, and heat treatment reaches 36-40HRC.
Alignment pin material is 60Si2MnA, and heat treatment reaches 58-62HRC.
The Rotary axle center error of clamping part, working end and location-plate is less than 0.02mm.
The Rotary axle center error of clamping part, grooved guide pad is less than 0.04mm.
Axle center and the V-type plate axial plane of symmetry error of clamping part are less than 0.04mm.
The beneficial effect of employing technique scheme is: the workpiece machining clamp of this fast aligning is by stationary positioned plate, workpiece is inserted alignment pin, then tightens lock-screw downwards, stuckly mark closely screw, V-type plate top tight workpiece cylindrical under its lock-screw, automatic capturing; Jig main body is provided with general clamping part, can realize different lathe quick-clamping, is applicable to the processing of similar 90 degree of union elbows; Highly versatile, efficiency improves.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Vehicle Processing folder of a kind of fast aligning of the present invention;
Fig. 2 is the A-A generalized section of Fig. 1;
In figure, 1-jig main body, 1.1-clamping part, 1.2-working end, 1.3-grooved guide pad, 2-lock-screw, 3-V template, 4-marks closely screw, 5-location-plate, 6-hold-down screw, 7-alignment pin, 8-workpiece.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is explained.
A kind of workpiece machining clamp of fast aligning, it mainly comprises jig main body 1, its jig main body 1 is provided with cylindrical clamping part 1.1 that one connects, fixture top plate working end 1.2 and symmetrical grooved guide pad 1.3, its working end 1.2 is provided with the lock-screw 2 be threaded, lock-screw 2 bottom is provided with annular notch, the annular notch of lock-screw 2 bottom embeds the web of one piece of V-type plate 3, what be provided with stuck lock-screw 2 in V-type plate 3 marks closely screw 4, namely promote V-type plate 3 after lock-screw 2 backspin to move down, the V-type of its V-type plate 3 lack can push up workpiece 8 cylindrical on; Jig main body 1 lower end is provided with the location-plate 5 of being locked by hold-down screw 6, and location-plate 5 is provided with alignment pin 7.
Workpiece 8 is inserted on alignment pin 7, location-plate 5 is lock onto on the downside of jig main body 1, backspin lock-screw 2 to V-type plate 3 top tight workpiece 8 again, mark closely screw 4 again, workpiece 8 has just fixed on jig main body 1, then the scroll chuck clamping part 1.1 of jig main body 1 being arranged on lathe can be processed.Different lathe quick-clamping can be realized, be applicable to the processing of similar 90 degree of union elbows; Highly versatile, efficiency improves.
