Description
Technical Field
The utility model relates to a frock clamp field, especially a piston top is kept away valve cave processing and is used frock.
Background
Each part of the piston is a core part of the engine, and the piston top in the piston is a main stressed part when bearing the explosion pressure in the cylinder, so that the service life and the safety of the engine are directly influenced by the processing quality, and the processing size and form and position tolerance are strictly controlled in the processing process of the piston top. When the piston top is machined in the traditional mode, the piston top needs to be horizontally placed on a tool clamp which is distributed in the same horizontal direction, then the tool clamp is machined in the working range of machining equipment, machining operation of one workpiece can only be completed within unit time, the production beat is seriously affected, and large workload is brought to operators due to frequent disassembly and clamping of the workpiece. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed can accelerate the production beat, improves production efficiency's piston top and keeps away valve hole frock for processing.
The technical solution of the utility model is that: the utility model provides a frock is used in processing of valve cave is kept away on piston top which characterized in that: the tool comprises a bottom plate 1, a square box 2 is arranged at the top of the bottom plate 1, positioning discs 3 and positioning mechanisms matched with the positioning discs 3 are arranged on four side surfaces of the square box 2, square box positioning holes 6 matched with workpiece positioning holes 5 on a piston top 4 are formed in the side surfaces of the square box 2, the positioning mechanisms comprise positioning pins 7 matched with the square box positioning holes 6,
positioning mechanism still includes three evenly distributed and compresses tightly the subassembly at positioning disk 3 outlying, compress tightly the subassembly and include fixed connection the position sleeve 8 on square chest 2, swing joint has compressing shaft 9 in the position sleeve 8, compressing shaft 9's tip then is provided with pressure plate portion 10, compressing shaft 9's hole activity has worn to have connect compressing bolt 11 in, and compressing bolt 11's one end is pressed at compressing shaft 9's tip, the other end then and position sleeve 8 between threaded connection.
Compared with the prior art, the utility model, have following advantage:
the tool for machining the valve avoiding hole in the piston top in the structural form is simple in structure, ingenious in design and reasonable in layout, aims at solving the problems of a tool clamp used in the traditional piston top machining process in the working process, designs a special structure, and is mainly structured into a square box, wherein positioning mechanisms are arranged on four side surfaces in the direction, namely the tool can clamp 4 piston tops to be machined at one time, so that the purposes of improving the machining efficiency and accelerating the production beat are achieved; meanwhile, the positioning mechanism is simple to operate, accurate in positioning, stable in clamping, simple in manufacturing process and low in manufacturing cost, so that the positioning mechanism has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: a tool for machining a valve avoiding hole in the top of a piston comprises a base plate 1 serving as a foundation, a square box 2 is arranged at the top of the base plate 1, positioning discs 3 and positioning mechanisms matched with the positioning discs 3 are arranged on four side faces of the square box 2, square box positioning holes 6 matched with workpiece positioning holes 5 in the top of the piston 4 are formed in the side faces of the square box 2, the positioning mechanisms comprise positioning pins 7 matched with the square box positioning holes 6,
positioning mechanism still includes three evenly distributed and compresses tightly the subassembly at positioning disk 3 outlying, compress tightly the subassembly and include fixed connection the position sleeve 8 on square chest 2, swing joint has compressing shaft 9 in the position sleeve 8, compressing shaft 9's tip then is provided with pressure plate portion 10, compressing shaft 9's hole activity has worn to have connect compressing bolt 11 in, and compressing bolt 11's one end is pressed at compressing shaft 9's tip, the other end then and position sleeve 8 between threaded connection.
The utility model discloses the working process of valve cave processing is kept away on piston top is as follows: firstly, respectively taking four piston tops 4 (workpieces) to be processed, respectively connecting the four piston tops 4 (workpieces) to positioning discs 3 on four side surfaces of a square box 2, adjusting the postures of the piston tops 4 to enable workpiece positioning holes 5 on the piston tops 4 and square box positioning holes 6 on the square box 2 to be coaxial, and then inserting positioning pins 7 into the square box positioning holes 6 and the workpiece positioning holes 5 from the inner side of the square box 2 to position the piston tops 4;
then, rotating the pressing shaft 9 to enable the pressing plate part 10 at the end part of the pressing shaft 9 to rotate towards the center direction of the piston top 4, enabling the pressing plate part 10 to rotate into a positioning groove formed in the side wall of the piston top 4, then screwing the pressing bolt 11, enabling the pressing bolt 11 to drive the pressing shaft 9 to move towards the direction 2, and finally pressing the piston top 4 by using the pressing plate part 10; and the three pressing assemblies on each side face operate according to the steps, and finally, the pressing assemblies press the piston top 4.
