Description

Sequential reaming and honing device for automobile connecting rod

Technical Field

The utility model belongs to the technical field of honing processing, especially, relate to a car connecting rod is hinge honing device in proper order.

Background

The reaming and honing is also called stroke honing, is a new process formed by combining common honing and conventional reaming processes, and can be used for processing hollow shapes such as through holes, blind holes, key slots, step holes and the like;

chinese utility model patent CN206811731U discloses a reaming honing rod of screw thread regulation, it just can promote the dabber to carry out axial displacement in the centre bore with its screw thread complex silk cover to drive through rotatory adjusting bolt, thereby prop up honing knife, it needs the reverse rotation bolt to pack up honing knife, thereby the dabber will be moved by the elastic force effect under a compression spring's effect and make honing knife pack up, this kind of mode is when implementing for guaranteeing that compression spring can play corresponding effect, it has enough big elasticity to need to guarantee compression spring, thereby even make the increase of slip frictional force between dabber and the cutter arbor also can be slided by the spring action, just so cause adjusting bolt to drive the dabber elasticity that compression spring need be overcome when removing, simultaneously if dabber and guide arm frictional force increase will probably lead to the dabber can not reset, lack the reliability.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a car connecting rod order hinge honing device, when having solved and using the spring to reset in the current hinge honing sword structure, reliable inadequately, there may be the problem that the dabber blocks and is difficult for reseing.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the content part of the utility model is as follows: the utility model provides a car connecting rod order reaming honing device, includes the main part dabber, its characterized in that, sliding fit has components of a whole that can function independently honing cover on the dabber, sliding connection has the spacer of spindle to put in components of a whole that can function independently honing cover side, threaded connection has a plurality of back adjusting nut on the spacer, still including setting up the preceding regulation structure at the spindle.

The utility model has the advantages that:

the utility model discloses a dabber, spindle sliding connection has the spacer, sliding fit has been put to the spacer side at spindle components of a whole that can function independently honing cover, components of a whole that can function independently honing sheathe in be provided with dabber sliding fit's abrasive band, spindle threaded connection has a plurality of back adjusting nut, dabber left end fixedly connected with flush end screw, flush end screw and preceding adjusting nut threaded connection, can carry on spacingly to the dabber through the adjusting nut who twists reverse two places, simple structure is practical, does not have the condition that the card takes place to pause, is worth promoting.

In the figure, 1, a mandrel; 2. a split honing sleeve; 3. a spacer sleeve; 4. a rear adjusting nut; 5. a strip chute; 6. a key pin; 7. a pin slot; 8. a flat-end screw; 9. adjusting the nut in front; 10. an inner hexagonal groove.

Detailed Description

The following description will be made in detail with reference to the accompanying fig. 1-2.

In the first embodiment, with reference to fig. 1-2, an automobile connecting rod sequential reaming and honing device includes a main body mandrel 1, which is preset, the mandrel 1 is made of 60Si2MnA material, the mandrel 1 is hollow inside, a split honing sleeve 2 is slidably fitted on the mandrel 1, a fitting position of the mandrel 1 and the split honing sleeve 2 is a conical structure, which is preset, the split honing sleeve 2 and the mandrel 1 are made of the same material, a grinding bar is slidably connected on the mandrel, after the mandrel 1 is connected with the split honing sleeve 2, the conical structure on the mandrel 1 is in mutual friction fit of the grinding bar, so that when the mandrel 1 slides relative to the split honing sleeve 2, the grinding bar can be driven to slide out of the split honing sleeve 2 by sliding of the mandrel 1, and retraction of the grinding bar is limited, a spacer 3 slidably connected to the mandrel 1 is disposed on a side of the split honing sleeve 2, and the spacer 3 and the mandrel 1 are connected in a preset manner: the spacer 3 is provided with a long sliding groove 5, the long sliding groove 5 is in sliding fit with a key pin 6 arranged on the mandrel 1, so that the spacer 3 and the mandrel 1 can only slide relatively but can not rotate relatively, the mandrel 1 is in threaded connection with a plurality of rear adjusting nuts 4 which are preset, in the present embodiment, the number of the rear adjusting nuts 4 is two, but it is not intended to limit the rear adjusting nuts 4 to only two, or more, can be selected according to the requirement, meets the requirement that all the post-adjusting nuts 4 can be limited through the superposition relationship among a plurality of nuts, that is, after the relative position of the mandrel 1 with respect to the spacer 3 is determined, the position of the mandrel 1 can be fixed by tightening the two rear adjusting nuts 4, and to achieve this function, a flat end screw 8 is fixedly connected in a cavity in the middle of the mandrel 1, a front adjusting nut 9 is connected on the flat end screw 8 in a threaded manner, the front adjusting nut is preset, the side wall of the front adjusting nut 9 is in contact fit with the split honing sleeve 2, so that after the two rear adjusting nuts 4 are limited and clamped, by rotating the front adjusting nut 9, the front adjusting nut 9 can finally contact with the split honing sleeve 2 so as to completely limit and preset the mandrel 1, the front adjusting nut 9 is provided with an inner hexagonal groove 10, and the mode of screwing the front adjusting nut 9 is increased, preset, in order to avoid relative rotation between the mandrel 1 and the split honing sleeve 2, the split honing sleeve 2 is provided with a pin groove 7, the pin groove 7 is internally matched with a fixed pin connected with the spacer sleeve 3, after the fixed pin enters the pin groove 7, the relative rotation between the spacer 3 and the split honing sleeve 2 will be limited, so that the split honing sleeve 2 can only slide along with the mandrel 1.

The utility model discloses when using, need earlier the drive before adjusting nut 9 or the roughly position of back adjusting nut 4, rotate the adjusting nut of another department afterwards, just can realize spacing to dabber 1 after screwing up, need notice at this in-process, need align with the relative position between spacer 3 and the components of a whole that can function independently honing rack earlier, guarantee the fixed pin in cotter way 7, when dabber 1 is loosened to needs, adjusting nut 4 can after unscrewing, in-process also only need twist after-adjusting nut 4 just can in later time, adjusting nut 9 is not hard up in the front only needs again do slightly again adjust just can, it needs to notice, although the description here seems very troublesome complicacy, but when the in-service use, the contrast is adjusted to available work piece, can not influence the regulation precision of abrasive band, and the utility model discloses it is convenient to dismantle, accomplish simple structure practicality really, be worth promoting.

The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
