Abstract

The utility model is suitable for bolt polishing field, a kind of bolt automatically grinding device is provided, provided with mill, distance measuring sensor etc., under the action of crane and decelerating motor, decelerating motor drives rotating cylinder and mill rotation, mill, which moves down, polishes to the screw thread upper surface on bolt, when mill is moved to bottommost, distance measuring sensor sends a signal to crane, crane band movable grinding disc is driven to move up, it polishes the lower surface of screw thread, realizes the upper and lower surface of the automatic bolt thread of polishing up and down, grinding effect is good.

Description

A kind of bolt automatically grinding device

Technical field

The utility model belongs to bolt polishing field more particularly to a kind of bolt automatically grinding device.

Background technique

Existing bolt removal oxide mode is artificially to polish, and using sand paper or grinding wheel, this polishing mode is imitated Rate is slow, and grinding effect is undesirable, the bottom of thread exist polishing less than place.

Utility model content

In view of the above problems, the purpose of this utility model is to provide a kind of bolt automatically grinding devices, it is intended to solve existing There is the bolt polishing technical problem that manual type is slow and effect is undesirable.

The utility model adopts the following technical solution:

A kind of bolt automatically grinding device, including pedestal are provided with fixture block, the side setting of the pedestal on the pedestal There is crane, the upper part of the crane is bent to form cross bar to the upper horizontal of the pedestal, and the cross bar is down-set There is hanger bracket, the top in the hanger bracket is fixed with a decelerating motor, and the decelerating motor lower end connects a rotation and hangs Ear, the rotation hangers are fixed with downwards a rotating cylinder, and the bottom outward bending of the rotating cylinder forms wing plate, under the rotating cylinder Side is equipped with mill, and there is threaded hole in the mill center, and threaded hole inner wall is coated with abrasive pastes, and the mill and the wing plate are solid It is fixed, distance measuring sensor is additionally provided on the cross bar.

Specifically, the side wall of the rotating cylinder forms a circle concave track from outside to inside, the bottom of the hanger bracket is inwardly curved It rolls over and bending part enters in the concave track, the upper lower wall of the concave track is provided inwardly with a circle idler wheel.

Specifically, the mill and the wing plate are locked by screw.

The beneficial effects of the utility model are: a mill is arranged in a kind of bolt automatically grinding device of the utility model, The upper and lower surface of the automatic bolt thread of polishing up and down is realized under the action of crane and decelerating motor, grinding effect is good.

Detailed description of the invention

Fig. 1 is a kind of facing structure figure of bolt automatically grinding device provided by the embodiment of the utility model；

Fig. 2 is the overlooking structure figure for the mill that utility model embodiment provides.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

In order to illustrate technical solution described in the utility model, the following is a description of specific embodiments.

Fig. 1 shows a kind of structure of bolt automatically grinding device provided by the embodiment of the utility model, for the ease of saying It is bright to illustrate only part relevant to the utility model embodiment.

As shown in Figure 1, a kind of bolt automatically grinding device, including pedestal 1, it is provided with fixture block 2 on the pedestal 1, it is described The side of pedestal 1 is provided with crane 3, and the upper part of the crane 3 is bent to form cross bar to the upper horizontal of the pedestal 1 4, the cross bar 4 is vertically provided with hanger bracket 5, and the top in the hanger bracket 5 is fixed with a decelerating motor 6, the deceleration 6 lower end of motor connects a rotation hangers 7, and the rotation hangers 7 is downward to be fixed with a rotating cylinder 8, the bottom of the rotating cylinder 8 to It is bent to form wing plate 9 outside, the lower section of the rotating cylinder 8 is equipped with mill 10, and there are threaded hole 11, threaded hole 11 in 10 center of mill Inner wall is coated with abrasive pastes, and the mill 10 is fixed with the wing plate 9, is additionally provided with distance measuring sensor 12 on the cross bar 4.

Bolt or band to be polished need the to be polished other equipment of bolt are fixed on the fixture block of bottom plate, model will be matched Mill be screwed in the bottom of rotating cylinder, then start crane and decelerating motor, according to the height of bolt thread bottommost Degree sets distance measuring sensor, and cross bar moves down, and mill moves down, and when mill and threaded bolt contacts, mill gives bolt downward pressure Power, decelerating motor drive rotating cylinder and mill rotation, polish the screw thread upper surface on bolt, when mill is moved to bottommost When, distance measuring sensor sends a signal to crane, and crane is driven to move up, and mill polishes to the lower surface of screw thread, mill Also it moves up and gives one, bolt and upward pressure, when cross bar returns to initial position, complete the polishing of a bolt.

As a kind of preferred structure of bolt automatically grinding device, the side wall of the rotating cylinder 8 forms one from outside to inside Concave track 13 is enclosed, the bottom of the hanger bracket 5 bends inwards and bending part enters in the concave track, the concave track 13 upper lower wall is provided inwardly with a circle idler wheel 14.As a kind of specific structure of bolt automatically grinding device, the mill Disk 10 and the wing plate 9 pass through screw locking 15.

Idler wheel is set in concave track and cooperates decelerating motor, the effect of mill and one, bolt deceleration can be given, avoided Reaction force excessive to the abrasion loss of decelerating motor, while obtaining from bolt by mill can save electric energy.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
