Description

Positioning device for machining spark plug hole in cylinder cover
Technical Field
The utility model relates to a machine tooling field, especially a cylinder head processing positioner for spark plug hole.
Background
The cylinder head is the core component of the engine, and is the main stressed accessory when bearing the explosion pressure in the cylinder, and the quality of the cylinder head directly influences the service life and the safety of the engine. The cylinder cover is required to be provided with a spark plug hole, and the quality of the machining quality of the spark plug hole can directly influence the power of the engine. Because the spark plug holes are distributed on the cylinder cover in an inclined mode, when the inclined spark plug holes are machined, the inclined tool is manufactured in the traditional machining mode, the spark plug holes are drilled and tapped by a drilling machine after being vertical, the mode is greatly influenced by human factors during machining, the position degree and the precision of the spark plug holes relative to the cylinder cover are difficult to guarantee, and the stability of product quality is difficult to guarantee. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
Disclosure of Invention
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 make things convenient for, swiftly, firmly carry out accurate location and press from both sides tightly to the cylinder head to guarantee product quality stability's positioner.
The technical solution of the utility model is that: the utility model provides a cylinder head processing positioner for spark plug hole which characterized in that: the device comprises a square box 1, wherein the direction is fixedly connected with a workbench 3 of a horizontal numerical control machine tool through a plurality of first bolts 2 which are uniformly distributed, a positioning plate 5 is connected to the side surface of the square box 1 through second bolts 4, a circular sinking groove 6 is formed in the center of the positioning plate 5, the sinking groove 6 is matched with a positioning excircle on a cylinder cover 10, a positioning column 7 is further arranged on the positioning plate 5, the positioning column 7 is matched with an assembling hole on the cylinder cover 10, meanwhile, four studs 8 are arranged on the positioning plate 5, the studs 8 are matched with the assembling holes on the cylinder cover 10, one end of each stud 8 is in threaded connection with the positioning plate 5, the other end of each stud 8 protrudes out of the surface of the cylinder cover 10, and meanwhile, a compression nut 9 is further in threaded connection with the stud 8 at one end.
Compared with the prior art, the utility model, have following advantage:
the positioning device for the cylinder cover to process the spark plug hole is simple in structure, ingenious in design and reasonable in layout, is designed aiming at the problems of a traditional cylinder cover positioning clamp in the working process, is of a special structure, is designed aiming at the problems of the traditional cylinder cover in the process of processing the spark plug hole, is designed to be a special positioning device, and is capable of directly utilizing a plurality of parts on the cylinder cover to realize positioning. And the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.
Drawings

Fig. 2 is a side view of an embodiment of the invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: a positioning device for machining a spark plug hole on a cylinder cover comprises a square box 1, the direction is fixedly connected with a workbench 3 of a horizontal numerical control machine tool through a plurality of first bolts 2 which are uniformly distributed, the side surface of the square box 1 is connected with a positioning plate 5 through a second bolt 4, the center of the positioning plate 5 is provided with a circular sinking groove 6, the sinking groove 6 is matched with a positioning excircle on a cylinder cover 10, a positioning column 7 is also arranged on the positioning plate 5, the positioning column 7 is matched with an assembling hole on the cylinder cover 10, meanwhile, four stud bolts 8 are arranged on the positioning plate 5, the stud bolts 8 are matched with assembly holes on the cylinder cover 10, one end of the stud 8 is connected to the positioning plate 5 in a threaded manner, the other end of the stud protrudes out of the surface of the cylinder cover 10, and meanwhile the stud 8 at the end is connected with a compression nut 9 in a threaded manner.
The utility model discloses cylinder head processing positioner for spark plug hole's working process as follows: firstly, a square box connected with a positioning plate 5 is fixedly connected to a workbench 3 of a horizontal numerical control machine tool through a plurality of first bolts 2, then a cylinder cover 10 is placed on the positioning plate 5, a positioning excircle on the cylinder cover 10 is ensured to be buckled into a sinking groove 6, a positioning column 7 on the positioning plate 5 is ensured to enter an assembly hole on the cylinder cover 10, all stud bolts 8 are ensured to enter corresponding assembly holes, finally a compression nut 9 is connected to one end of each stud bolt 8 protruding out of the surface of the cylinder cover 10, and the cylinder cover 10 is compressed on the positioning plate 5 by the compression nut 9, so that positioning and clamping are realized;
at this time, the horizontal numerically controlled machine tool can process the spark plug hole 11 on the cylinder head 10, push out the tool after the processing is finished, unscrew all the gland nuts 9, remove the cylinder head 10 from the positioning plate 5, and replace another new cylinder head 10.
