Abstract

The invention relates to a clamp capable of rotating positioning and belongs to the field of machining. The clamp comprises an annular disc, a positioning shifting pin, a support, a gear, a gear control part and a positioning part. The positioning part is mounted at the edge, close to an inner ring, of the annular disc and used for clamping a to-be-machined part. The positioning shifting pin vertical to the face of the disc of mounted outside the positioning part. At least three groups of fixed pulleys are mounted in the vertical direction of the support. The bearing points of the fixed pulleys form arc faces. The annular disc falls on the fixed pulleys. The gear is fixed on the support. By the cooperation of the gear and the positioning shifting pin, control of the rotating angles and positions of the annular disc is achieved. The clamp is simple in structure, convenient to operate and worthy of market popularization and application, a large amount of manpower and clamping and positioning time is saved, and work efficiency is increased.

Description

The fixture of rotatable location

Technical field

The invention belongs to field of machining, be specifically related to a kind of fixture for needing rotating machined workpiece to position.

Background technology

In mechanical processing process, often need to carry out to some parts the processing of different positions, and for larger parts, carrying out in the process of different position processing, the parts that need to the overturn luggage of going forward side by side clamps position, and then could process parts, because large parts need more artificial in switching process, and upset and location also need to spend the more time, and operating efficiency is lower.

Summary of the invention

In upset and clamping position fixing process, need the more artificial and low technical problem of operating efficiency that the time causes for solving large parts, the invention provides after a kind of clamping parts the fixture of rotatable location.

The fixture of rotatable location, comprise circular disk, location finger, support, gear, gear operating element, positioning element, it is characterized in that: circular disk Shang Jinneihuan edge is provided with positioning element, for clamping part to be processed, outside positioning element the location finger perpendicular to disc face is installed; Described support vertical direction is provided with at least three group fixed pulleys, between the hard point of fixed pulley, forms arc surface, and circular disk falls within on fixed pulley, and the radius of fixed pulley is less than the distance between disk outer ledge and location finger; Gear is fixed on support, and gear teeth is meshed with location finger, and under the motion of gear operating element, gear rotates, and gear teeth drives location finger to rotate, and circular disk rotates with location finger, drives the to be processed part of clamping on disk to rotate.

The present invention utilizes coordinating between gear and location finger, has realized the control to shape shape disc rotary angle and position, simple in structure, easy to operate, save a large amount of artificial and clamping positioning time, improved operating efficiency, there is higher marketing and using value.

Accompanying drawing explanation

Drawing of the present invention is described as follows:

Fig. 1. the structure chart of rotatable positioning fixture;

Fig. 2. in Fig. 1, A-A is to cutaway view;

Fig. 3. the partial perspective view of rotatable positioning fixture;

In figure: 1. fixed pulley 2. disk 3. gear operating element 4. gear 5. supports 6. are located finger 7. positioning elements.

The specific embodiment

Below in conjunction with accompanying drawing, that the present invention is further illustrated is as follows:

The fixture of rotatable location, comprise circular disk 2, location finger 6, support 5, gear 4, gear 4 operating elements 3, positioning element 7, it is characterized in that: circular disk 2 Shang Jinneihuan edges are provided with positioning element 7, for clamping part to be processed, outside positioning element 7 the location finger 6 perpendicular to 2, disk is installed; Described support 5 vertical directions are provided with at least three group fixed pulleys 1, between the hard point of fixed pulley 1, form arc surface, and circular disk 2 falls within on fixed pulley 1, and the radius of fixed pulley 1 is less than the distance between disk 2 outer ledges and location finger 6; Gear 4 is fixed on support 5, and gear 4 teeth are meshed with location finger 6, under the motion of gear 4 operating elements 3, gear 4 rotates, the moving location of gear 4 cingulums finger 6 rotates, and circular disk 2 rotates with location finger 6, drives the to be processed part of clamping on disk 2 to rotate.

In the time using the fixture of rotatable location, part to be processed is passed to disk 2 inner rings, fixing with respect to disk 2 by positioning element 7, by gear 4 operating elements 3, gear 4 is rotated again, gear 4 drives location finger 6 to rotate, thereby the part to be processed that drives disk 2 and be arranged on disk 2 rotates, the rotation of disk 2 realizes on fixed pulley 1, so the radius of fixed pulley 1 is less than the distance between disk 2 outer ledges and location finger 6, location finger 6 can not affect the rotation process of disk 2, when part to be processed arrives after the station that needs processing, stop the rotation of gear 4, treating processing parts processes, and then transmitting gear 4, make part to be processed arrive next processing stations, again part is processed, rotation and the location of part to be processed in whole process, all control and realize by gear 4.

Above-mentioned part rotates to after station to be processed, only by no longer rotating of gear 4 and operating element, the whole disk 2 with part is positioned, when part to be processed stressed in process, just may occur that part to be processed drives disk 2, and then driven gear 4 counter-rotates, cause locating inaccurate, for this reason, the present invention is also designed with the locating hole corresponding to multiple processing stations on gear 4, on corresponding support 5, be also designed with locating hole, in the time arriving a certain processing stations, the locating hole that this processing stations is corresponding utilizes bearing pin to be connected with the locating hole on support 5.

The flip angle of part to be processed is by the rotational angle control of location finger 6, simultaneously in the time that part to be processed turns to required angle, can also between rotating disk and support 5, guarantee the accuracy of the rotational angle of part to be processed by Design Orientation pin, and part to be processed is located.

Gear 4 operating elements 3 in the present invention are selected the pattern of gearbox, in gearbox, are turbine worm structure, and control handle is connected with scroll bar, and control handle rotarily drives scroll bar rotation, rotate under the drive at scroll bar at turbine, and then the rotation of driven gear 4.

Protection scope of the present invention is not limited only to the disclosed technical scheme of specific embodiment part, all location finger rotations utilizing on gear driven disk, and then realize the rotating localization jigs that part to be processed rotates, all fall into protection scope of the present invention.
