Description

Gear chamber positioning tool

Technical Field

The utility model relates to a technical field of diesel engine assembly, more specifically say, it relates to a gear room positioning frock.

Background

When assembling an engine, it is necessary to fit the driving gear of the injection pump into the gear housing, and the current mounting method is as shown in fig. 1-2: the guide bar 22 with four pins 21 at one end is placed on the side of the driving gear of the injection pump, then the driving gear is guided into the gear chamber through the guide bar 22 until the cover plate of the injection pump is completely attached to the cover plate of the gear chamber, then the guide bar 22 is taken out, and the engine is assembled continuously.

The guide rod 22 is inconvenient to position through the four pins 21, so that more time is spent on the pins, and the installation beat is influenced; meanwhile, the pin 21 cannot effectively fix the tool, and the guide rod 22 is easy to drop in the using process, so that the tool is broken.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is not enough to prior art, a gear room positioning frock is provided, can be firm install on drive gear, be difficult for dropping.

The technical scheme of the utility model lies in: the utility model provides a gear room positioning frock, includes the uide bushing, the one end of uide bushing is equipped with a bellied spacing ring, the terminal surface of uide bushing forms a recess with the spacing ring, it has at least one magnet piece to inlay in the recess.

In a further improvement, a gap is arranged between the magnet block and the end face of the groove.

Further, at least one positioning pin is arranged in the groove.

Furthermore, a central hole coaxial with the limiting ring is arranged in the groove.

Furthermore, the other end of the guide sleeve is a conical end with a conical structure.

Furthermore, a positioning ring is arranged between the conical end and the limiting ring.

Furthermore, a handle is arranged on the end face of the conical end.

Furthermore, the handle is provided with anti-skid grains.

Advantageous effects

The utility model has the advantages that:

1. the driving gear is sleeved in the groove, the magnetic attraction of the magnet blocks embedded in the groove to the driving gear enables the tool to be adsorbed on the driving gear, the tool is effectively prevented from dropping, and the reliability of the tool is greatly improved. The tool is simple in structure and low in manufacturing cost; after the installation, the falling is not easy, the disassembly and the assembly are easy, the assembly quality is effectively ensured, and the assembly efficiency is improved.

2. The clearance between magnet piece and the recess terminal surface can effectually reduce the degree that drive gear is magnetized by the magnet piece, guarantees the appeal of magnet piece to drive gear.

3. When the drive gear is guided, the conical end of the guide sleeve is beneficial to guiding, and the guide sleeve has a good guiding effect. And the locating ring of this frock matches with the drive gear hole on the gear room, when advancing the drive gear direction into the gear room, still can fix a position drive gear.

Detailed Description

The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.

Referring to fig. 3-4, a gear chamber assembling and positioning tool includes a guide sleeve 8, where the guide sleeve 8 is a cylinder. One end of the guide sleeve 8 is provided with a raised limit ring 1, and the inner diameter of the limit ring 1 is matched with the outer diameter of the driving gear. The end surface of the guide sleeve 8 and the limiting ring 1 form a groove 2, and the groove 2 is used for placing a driving gear. Two magnet blocks 5 are embedded in the groove 2. When concrete implementation, with drive gear cover in recess 2, through inlaying the magnetic attraction of magnet piece 5 in recess 2 to drive gear, make this frock adsorb on drive gear, effectively prevented the frock and dropped, improved its reliability greatly. The tool is simple in structure and low in manufacturing cost; after the installation, the falling is not easy, the disassembly and the assembly are easy, the assembly quality is effectively ensured, and the assembly efficiency is improved.

The gap 6 is arranged between the magnet block 5 and the end face of the groove 2, so that the degree of magnetization of the driving gear by the magnet block can be effectively reduced, and the attraction of the magnet block to the driving gear is ensured. At least one positioning pin 3 is arranged in the groove 2, and specifically, one positioning pin 3 is arranged in the groove 2 and used for guiding and positioning the tool when the tool is installed; and the positioning pin 3 and the two magnet blocks 5 are uniformly arranged in the groove 2. The groove 2 is internally provided with a central hole 7 which is coaxial with the limiting ring 1, and the central hole 7 is matched with a central shaft on the driving gear. When the tool is installed on the driving gear, the center hole 7 is matched with the center shaft of the driving gear, so that the tool can be better guided and positioned when being installed.

The other end of the guide sleeve 8 is a conical end 81 with a conical structure, and the conical end 81 is beneficial to guiding and has a good guiding effect, so that the tool is easier and more convenient to install. A positioning ring 82 is arranged between the conical end 81 and the limiting ring 1, and the positioning ring 82 is matched with a driving gear hole on the gear chamber. When the driving gear is guided into the gear chamber, the positioning ring 82 can also position the driving gear, so that the tool can guide and position the driving gear simultaneously, and the assembly efficiency is greatly improved. A handle 9 is arranged on the end face of the conical end 81 and used for assembling and disassembling the tool conveniently and quickly. The handle 9 is provided with anti-skid grains 10, so that an operator can obtain a better grabbing force when the tool is disassembled and assembled, and the tool is more convenient and easy to disassemble and assemble.

The above is only the preferred embodiment of the present invention, and it should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which will not affect the utility model and the utility of the patent.
