Description
Technical Field
The utility model relates to a for military use naval vessel bent axle processing equipment field especially relates to a workpiece positioning frock that is used for processing for military use naval vessel bent axle on bent axle grinding machine.
Background
The crankshaft of the military naval vessel is processed on a crankshaft grinding machine, the relative position of the crankshaft of the military naval vessel must be ensured to be accurate, the process is commonly called 'alignment', in general, the crankshaft grinding machine uses a tip to perform alignment when grinding the crankshaft of the military naval vessel, but because the crankshaft of the military naval vessel is heavy, a tip hole on the crankshaft of the military naval vessel is easy to damage and deform, or the tip hole is rusted due to too long time for the crankshaft of the military naval vessel, which can cause difficulty in alignment work.
SUMMERY OF THE UTILITY MODEL
For solving current crankshaft grinder because the fragile problem that leads to the alignment work difficulty of apex hole at the grinding military naval vessel bent axle in-process, the utility model provides a be used for processing the work piece location frock of military naval vessel bent axle on the bent axle grinding machine.
In order to achieve the above object, the utility model adopts the following technical scheme: a workpiece positioning tool for machining a crankshaft of a military naval vessel on a crankshaft grinder comprises a packing, a four-jaw chuck, a tip, a sleeve, a spring, an ejector rod, a nut, a pressing sheet and a wrench; the four-jaw chuck passes through bolt and packing fixed connection, is equipped with through-hole A in the middle of the four-jaw chuck, is equipped with through-hole B in the middle of the packing, and sleeve one end is located through-hole A and through-hole B, and sleeve one end is equipped with and is used for pushing into top hole A, is equipped with the cavity in the sleeve, and the sleeve other end is equipped with the screw hole A that is used for ejector pin one end to stretch into the cavity, sets gradually preforming, nut and spring in the cavity, the spring other end and top contact, and the ejector pin other.
The utility model has the advantages that: the center and the four-jaw chuck are combined together, so that the alignment accuracy of the workpiece is ensured, and the alignment speed can be improved; the utility model discloses compact structure, easy operation, not hinder crankshaft grinder and work piece, avoided the change of the work piece relative position that work piece apex hole wearing and tearing arouse, furthest's reduction the variability of work piece alignment.

Detailed Description
A workpiece positioning tool for machining a crankshaft of a military naval vessel on a crankshaft grinder is disclosed, wherein the workpiece is the crankshaft of the military naval vessel and comprises a packing 1, a four-jaw chuck 2, a tip 3, a sleeve 4, a spring 5, an ejector rod 6, a nut 7, a pressing sheet 8 and a wrench 9; four-jaw (holding) chuck 2 passes through bolt and 1 fixed connection of packing, be equipped with through-hole A in the middle of four-jaw (holding) chuck 2, be equipped with through-hole B in the middle of the packing 1, 4 one ends of sleeve are located through-hole A and through-hole B, 4 one ends of sleeve are equipped with the hole A who is used for pushing into top 3, be equipped with the cavity in the sleeve 4, the 4 other ends of sleeve are equipped with the screw hole A who is used for 6 one end of ejector pin to stretch into the cavity, set gradually preforming 8 in the cavity, nut 7 and spring 5, the spring 5 other end contacts with top 3.
The packing is arranged on a crankshaft grinding machine, a packing 1 is fixed on one side of a head chuck 10 at one end of the crankshaft grinding machine through a bolt, a spigot matched with the spigot of the head chuck 10 is arranged on the packing 1 for positioning, a hole for a sleeve 4 to pass through is formed in the middle of the head chuck 10, the other end of the sleeve 4 and a mandril 6 are both positioned in the crankshaft grinding machine, and the other end of the mandril 6 extends out of one end of the crankshaft grinding machine and is provided with a wrench 9; in addition, the embodiment can also be installed on a common grinding machine.
The center 3 is used for preliminary alignment of a workpiece, the center 3 is used for supporting a center hole of the workpiece, after supporting, if the jumping amount is within the range required by the workpiece, the workpiece is clamped by the four-jaw chuck 2, the four jaws on the four-jaw chuck 2 are used for aligning the workpiece in four directions, after alignment, the workpiece can be used as a poking and inserting tool due to the holding of the workpiece, and the trouble that the workpiece needs to be poked and inserted when the center 3 is used for alignment is avoided; the spring 5 has the function of ensuring that the pressure of the center 3 is proper through elastic force so as to reduce the bending deformation caused by the fixed force to the workpiece and the bending deformation caused by thermal expansion in the processing; the ejector rod 6 has the effects that when the wrench 9 is rotated, the ejector rod 6 and the spring 5 together prop or withdraw the tip 3, and the tip 3 is directly propped in and clamped in the hole A; the nut 7 has the function that after the wrench 9 applies force to the center 3, the center 3 is locked, so that the pushing force is always kept unchanged; the pressing sheet 8 is used for locking the nut 7; in the embodiment, the center 3 and the four-jaw chuck 2 are combined together, and the two functions complement each other, so that the operation is simple and clear, the quality hidden trouble is avoided, the alignment speed is improved, and the alignment precision is also improved, thereby improving the production efficiency, having compact device structure and simple operation, not damaging a crankshaft grinding machine and a workpiece, avoiding the change of the relative position of the workpiece caused by the deformation and abrasion of the copper foil after the alignment of the copper foil, and reducing the variability of the alignment of the workpiece to the maximum extent; the workpiece of the present embodiment is referred to as a crankshaft.
The above description is only the specific implementation manner of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the design of the present invention within the technical scope of the present invention.
