Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Examples
As shown in fig. 1, a frock of cold oil gallery hole in processing diesel engine ring insert piston, includes base 11, sets up clamp plate 12 and the auxiliary positioning device 20 of setting in base 11 side above base 11, auxiliary positioning device 20 includes the fixed plate 21 of vertical setting and two level settings's locating pin 22, the lower extreme of fixed plate 21 and base 11 fixed connection form "L" shape, locating pin 22 fixed connection is in the top of fixed plate 21, and two locating pin 22 stretch out the same length of fixed plate 21, be equipped with the locating hole 121 that link up from top to bottom on clamp plate 12.
The cold oil channel hole of the diesel engine ring-inserted piston is processed and formed from the direction of the seam allowance, and the end surface opposite to the seam allowance is flat, so that the accurate positioning can not be carried out, the tool of the utility model utilizes the peripheral circle characteristic of the diesel engine ring-inserted piston to be matched with the positioning nail 22 to position the diesel engine ring-inserted piston, according to the principle of two points and radius circle, the positions of the pistons can be determined by the two heads of the positioning pins 22 and the diameters of the pistons, the positioning is completed only by enabling the side walls of the pistons to be close to the two positioning pins 22 during positioning, so that the relative positions of the pistons and the positioning holes 121 are determined, then compress tightly fixedly through base 11 and clamp plate 12 to diesel engine ring inserted piston, the processing cutter can accomplish the processing in cold oil duct hole through locating hole 121, and whole frock guarantees that the cold oil duct satisfies the tolerance range of regulation in the diesel engine ring inserted piston of processing, has improved the machining precision greatly.
Be equipped with cylinder 14 between base 11 and the clamp plate 12, the bottom and the base 11 fixed connection of cylinder 14, the telescopic link and the clamp plate 12 fixed connection of cylinder 14, the quantity of cylinder 14 is two, and two cylinders 14 fixed mounting are in the diagonal angle of base 11. The two air cylinders 14 can well meet the power requirement and can control the investment of economic cost, and the two air cylinders are arranged on the same edge due to the fact that the pressing plate 12 is of a plate-shaped structure, so that the structure is poor in stability and easy to damage; this problem is well circumvented by the diagonal arrangement of the two cylinders 14, the cylinder type used in this embodiment being SDA40 × 20.
Still be provided with support guide bar 31 between base 11 and the clamp plate 12, support guide bar 31's bottom through supporting guide bar seat 32 fixed mounting on base 11, support guide bar 31 food body of rod run through clamp plate 12 and with clamp plate 12 sliding connection. Because the requirement on the machining precision of the cold oil duct in the piston of the diesel engine insert ring is high, the offset vibration of the pressing plate 12 cannot be controlled by only using the air cylinder 14, and the supporting guide rod 31 is additionally arranged for stroke guide of the pressing plate 12, so that the cold oil duct machining scrapping caused by offset of the pressing plate 12 in the pressing process is prevented.
The number of the support guide rods 31 is two, the two support guide rods 31 are fixedly installed at the diagonal corners of the base 11, and the support guide rods 31 and the air cylinders 14 are alternately arranged. Because the air cylinder 14 is arranged on one oblique diagonal of the pressure plate 12, and the other oblique supporting guide rod 31 is arranged, the whole tool forms a balance structure, which is beneficial to maintaining stability.
the inner wall of the positioning hole 121 is also fixedly connected with a positioning hole guide sleeve 122. The processing cutter and the pressing plate 12 are both of metal structures, the inner wall of the positioning hole 121 can abrade the processing cutter in the processing process, the processing cutter is protected by arranging the positioning hole guide sleeve 122 made of polymethyl methacrylate, and meanwhile, the positioning processing of the cold oil duct is facilitated by the butt joint of the positioning hole guide sleeve 122 and the processing cutter.
A positioning seat 13 is arranged between the base 11 and the pressure plate 12, and the positioning seat 13 is fixedly installed on the top surface of the base 11. A lot of metal fillings and smear metal liquid can be stayed to clamp plate 12 in the course of working, directly places the piston in clamp plate 12 and hardly guarantees its equilibrium and stability, sets up behind positioning seat 13 and form the difference in height between clamp plate 12, guarantees the cleanliness factor on the installation face of piston to improve equilibrium and stability after the piston is fixed.
During processing, the spigot of the piston is upward and prevented from being positioned on the positioning seat 13, the piston is abutted against the two positioning nails 22, the cylinder 14 is controlled to work through the electromagnetic control valve, the pressing plate 12 is driven to move downwards and compress the piston, and the processing cutter processes a cooling oil passage from the positioning hole 121.
