Description

Clamp for bearing ring machining lathe

Technical Field

The utility model relates to a lathe technical field specifically is a bearing ring adds anchor clamps for processing lathe.

Background

The rolling bearing mainly comprises an outer ring, an inner ring, a rolling body and a retainer, wherein four parts are produced independently in the production process of the rolling bearing, then the four parts are assembled, the inner ring and the outer ring of the rolling bearing are collectively called as a bearing ring, the inner ring and the outer ring of the bearing ring need to be turned in the production process of the bearing ring, a three-jaw chuck is generally adopted to clamp the outer ring of the bearing ring when the inner ring of the bearing ring is turned, then the bearing ring is controlled to rotate, and the turning head turns the inner ring of the bearing ring.

Although the bearing ring can be clamped by the clamping method of the three-jaw chuck, when the precision requirement of the processed bearing ring is high, the circle center position of the bearing ring is easy to deviate from the rotating shaft center as long as one jaw of the three-jaw chuck slightly deforms and deviates or is worn when clamping the bearing ring, so that the ovality of the processed inner ring of the bearing ring is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bearing ring adds anchor clamps for lathe to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a bearing ring processing clamp for a lathe comprises:

the fixing base, its side is provided with annular chuck, it has a plurality of draw-in grooves to follow hoop evenly distributed in the chuck, all block in the draw-in groove and be equipped with along its gliding slider, be provided with the edge on the slider the radial outside push rod of chuck, the tip of push rod pierces through the draw-in groove lateral wall is provided with the fixture block, is provided with the tip on the fixture block and stretches out the jack catch of chuck side, the chucking has the lasso on the jack catch, the push rod is located partial cover in the draw-in groove is equipped with compression spring, the inner ring side of chuck be provided with the air inlet of draw-in groove intercommunication, the air inlet is.

Furthermore, the inner side wall and the outer side wall of the clamping jaw are both of arc structures, and rubber pads are wrapped on the clamping jaw.

Furthermore, the chuck is provided with an avoiding groove for the clamping block to be clamped in.

Furthermore, the fixture block with the jack catch passes through the screw and can dismantle the connection.

Furthermore, the number of the clamping grooves is eight.

Compared with the prior art, the beneficial effects of the utility model are that: by arranging the plurality of clamping claws, when the ferrule is clamped, all parts are stressed more uniformly, and deformation is prevented; the synchronous contraction of the clamping jaws is realized through the control of the air cylinder, the alignment of the axis of the ferrule and the axis of the chuck is ensured, and the processing precision is ensured.

Drawings

FIG. 1 is a schematic side view of the present invention,

figure 2 is a schematic diagram of the front structure of the utility model,

the clamping device comprises a fixing seat 1, a fixing seat 2, a chuck 3, a clamping groove 4, a sliding block 5, a push rod 6, a clamping block 7, a clamping jaw 8, a ferrule 9, a spring 10, an air inlet 11, an inflation cylinder 12 and an avoiding groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to FIG. 1And FIG. 2The utility model provides a technical scheme: a bearing ring processing clamp for a lathe comprises:

fixing base 1, its side is provided with annular chuck 2, there are a plurality of draw-in grooves 3 along hoop evenly distributed in the chuck 2, all block in the draw-in groove 3 and be equipped with along its gliding slider 4, be provided with the edge on the slider 4 the radial outside push rod 5 of chuck, the tip of push rod 5 pierces through 3 lateral walls of draw-in groove are provided with fixture block 6, are provided with the tip on the fixture block 6 and stretch out the jack catch 7 of 2 sides of chuck, the chucking has lasso 8 on the jack catch 7, push rod 5 is located partial cover in the draw-in groove 3 is equipped with compression spring 9, the inner ring side of chuck 2 be provided with the air inlet 10 of 3 intercommunications of draw-in groove, air inlet 10 is connected with and.

The inner side wall and the outer side wall of the clamping jaw 7 are both of arc structures, and rubber pads are wrapped on the clamping jaws.

The chuck 2 is provided with an avoiding groove 12 for the clamping block to be clamped in.

The clamping block 6 is detachably connected with the clamping jaw 7 through a screw.

The number of the clamping grooves 3 is eight.

The working principle is as follows: when the clamping ring clamping device is used, gas is filled into the cylinder to push the clamping block to expand outwards, the clamping jaws matched with the clamping ring are replaced according to the size of the clamping ring, then the clamping ring is placed between the clamping jaws, the gas in the cylinder is extracted, and the sliding block moves inwards under the pushing of the compression spring, so that the clamping block and the clamping jaws are driven to contract inwards to clamp the clamping ring.
