Abstract
The utility model discloses a machining clamp of a differential mechanism shell body. The machining clamp of the differential mechanism shell body comprises three Z-shaped clamping jaws. The machining clamp of the differential mechanism shell body is characterized in that a lower transverse connecting plate of each clamping jaw is provided with vertical connection through holes, the bottom surface of the outer end portion of each clamping jaw is provided with a concave step which is opposite to the bottom surface of a vertical connecting plate, the inner surface of an upper transverse jaw plate of each clamping jaw is an arc surface which is matched to the outer circle face of a workpiece, and each arc surface is provided with a vertical groove. When the machining clamp of the differential mechanism shell body is used, the clamping jaws are respectively fixed on a clamping plate of a machine tool with bolts through the vertical connecting through holes, the three clamping jaws are driven to be unfolded simultaneously through a hydraulic mechanism of the machine tool, the clamping jaws are folded inwards after a workpiece blank is installed in the clamping jaws, and therefore the workpiece is precisely located and clamped. Due to the fact that the vertical groove is formed in the inner surface of each jaw plate, the area of the contact face between the clamp and the workpiece is reduced, clamping is firm, the locating precision is high, operation is convenient, the machining clamp of the differential mechanism shell body is safe and reliable, and the production efficiency is high.
Description
Technical field
The utility model relates to a kind of mechanical grip instrument, particularly a kind of differential casing clamp for machining.
Background technology
At present, process bowlder as external as vehicle differential gear shell, generally adopt scroll chuck or monoblock type disk claw to clamp its cylindrical, fixture is face with the housing cylindrical and contacts, and contact area is large, clamps not strongly solid, poor safety performance, production efficiency is low, and product quality is difficult to control.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned weak point, and provides a kind of clamping firm, and positioning precision is high, easy to operate, safe and reliable, the differential casing clamp for machining that production efficiency is high.
The purpose of this utility model is achieved in that a kind of differential casing clamp for machining, comprise three " Z " shape claws, it is characterized in that on the lower, transverse connecting plate in each claw having vertical connecting through hole, bottom surface, outer end relatively vertical connecting plate bottom surface that the concave station rank are arranged, upper lateral claw-plate inner face in claw is the arc surface matched with the excircle of workpiece face, has vertical slot on arc surface.
The utility model is owing to adopting above design, during use, the lower, transverse connecting plate of three claws is inserted in respectively on the locating piece of lathe clamp, after radially being adjusted to the endoporus center and lathe central axes of three claws compositions, by bolt, by vertical connecting through hole, claw is fixed on the clamp of lathe.Hydraulic mechanism in lathe drives three claws and opens simultaneously, pack into and inwardly shrink again after workpiece blank, thereby realize workpiece is accurately located to clamping, the claw-plate inner face has vertical slot, has reduced the contact-making surface of fixture and workpiece, and clamping firmly, positioning precision is high, easy to operate, safe and reliable, production efficiency is high.
The accompanying drawing explanation
Fig. 1 is single claw structure schematic diagram of the present utility model.
The specific embodiment
Now by reference to the accompanying drawings the utility model is made to detailed description.
A kind of differential casing clamp for machining, comprise three " Z " shape claws as shown in Figure 1, on lower, transverse connecting plate 5 in each claw, there are vertical connecting through hole 4, bottom surface, outer end relatively the concave station rank to be arranged vertical connecting plate 1 bottom surface, upper lateral claw-plate 3 inner faces in claw are the arc surface matched with the excircle of workpiece face, have vertical slot 2 on arc surface.
