Abstract

The invention relates to a positioning device for manufacturing a fine screen. The ridge groove positioning device of a metal welding fine screen is characterized by comprising a stationary axle, an axle bed, a wire supporting disk, an annular gear and a wire pressing wheel, wherein the stationary axle is fixed on a bracket; the middle of the wire supporting disk is sheathed on the stationary axle; the annular gear is sheathed on the wire supporting disk; a screen wire is clamped in a tooth groove by the wire supporting disk; the annular gear is installed on a rotary frame; the wire pressing wheel is arranged on the position on the inner side surface of a wire screening barrel, which corresponds to an electric welding wheel; the middle of the wire pressing wheel is sheathed on the axle of the axle bed; the axle bed is fixed on the stationary axle; and on the tangent part of the upper part of the excircle of the wire pressing wheel and the wire screening barrel, the wire pressing wheel presses the screen wire into the ridge groove of the tooth groove to be positioned. The ridge groove positioning device has the characteristic of high precision; the cross sections of the screen wires of various screens are positioned and welded by changing the tooth shape of the annular gear; the screen with any screen tooth distance is positioned and welded by changing the tooth distance of the annular gear or arranging one ridge in every two lines, or arranging one ridge in every three lines; and the requirements of the cross sections of the screen wires of various screens are realized by changing the tooth shape of the annular gear.

Description

The bank groove positioner of metal solder fine screen mesh

Technical field

The present invention relates to a kind of positioner of making the metal solder fine screen mesh, can be used for multiple metal solder fine screen mesh.

Background technology

During the welding of metal solder screen cloth, be subjected to the influence of high temperature and impressed pressure effect, sieve seam trueness error is bigger, and is less to the sieve tooth pitch, and the welding fabrication of the metal solder fine screen mesh that the required precision of sieve seam is high just can not be realized.

Summary of the invention

The object of the present invention is to provide the bank groove positioner of the high metal solder fine screen mesh of a kind of precision.

To achieve these goals, technical scheme of the present invention is: the bank groove positioner of metal solder fine screen mesh, it is characterized in that it comprises fixed axis, axle bed, holder silk dish, ring gear, silk pressing wheel, fixed axis is fixed on the support, and the middle part of holder silk dish is enclosed within on the fixed axis; The inner periphery of ring gear is provided with a plurality of teeth groove, and the section of teeth groove is identical with the section of silk screen; Silk screen is contained in the teeth groove, and all silk screens constitute the silk screen tube of palisade; Ring gear is enclosed within on the holder silk dish, and holder silk dish is stuck in silk screen in the teeth groove, and ring gear is installed on the swivel mount; Medial surface and electric welding wheel corresponding position at the silk screen tube are provided with silk pressing wheel, and the middle part of silk pressing wheel is enclosed within on the axle of axle bed, and axle bed is fixed on the fixed axis, and at the cylindrical top and the tangent place of silk screen tube of silk pressing wheel, the silk pressing wheel is pressed into bank groove location in the teeth groove with silk screen.

The section of described teeth groove is circular, trapezoidal or triangle.

The invention has the beneficial effects as follows:

1, owing to adopted all silk screen banks in the teeth groove of ring gear, be pressed in bank groove location welding in the teeth groove by the silk pressing wheel, be that spacing between silk screen and the silk screen is by the spacing fastening between teeth groove and the teeth groove, silk screen can not misplace in slippage during welding, has realized that the bank groove of the fine screen mesh that high accuracy sieve seam and serration distance require is located welding forming.

2, the profile of tooth of change ring gear can realize the location welding of multiple screen cloth section, as circular net, trapezoidal net, network of triangle etc.

3, change the tooth pitch of ring gear or, can realize the location welding of any one tooth pitch screen cloth every two banks one, every three bank first-class.

4, change the wire of wire dish apart from the welding that can realize square hole net, slotted hole net, bar seam net etc.

The specific embodiment

Further describe the present invention below in conjunction with accompanying drawing:

As shown in Figure 1 and Figure 2, the bank groove positioner of metal solder fine screen mesh, it comprises fixed axis 1, axle bed 2, holder silk dish 4, ring gear 6, silk pressing wheel 10, and fixed axis 1 is fixed on (fixed axis does not rotate) on the support, and the middle part of holder silk dish 4 is enclosed within (promptly holder silk dish 4 can rotate) on the fixed axis 1;

The inner periphery of ring gear 6 is provided with a plurality of teeth groove 5, and (described a plurality of teeth groove are 200-10000 teeth groove, and concrete number is determined as required; The part teeth groove that only drawn among Fig. 2, other omission), the section of teeth groove is identical with the section of silk screen 3, and the slot pitch between the adjacent sheaves equates that with the sieve tooth pitch silk screen 3 is contained in (silk screen 3 is along circumferential arrangement) in the teeth groove 5, the silk screen tube of all silk screens 3 formation palisades; Ring gear 6 is enclosed within on the holder silk dish 4 and (is adorning holder silk dish 4 in the centre of ring gear 6), and holder silk dish 4 is stuck in silk screen 3 in the teeth groove, and ring gear 6 is installed in (among the figure draw in the end) rotation on the swivel mount, and promptly silk screen tube, holder silk dish 4 are also with ring gear 6 one rotation synchronously; Brush 7 contacts with ring gear 6; Adorning electric welding wheel 8 in the side of silk screen tube outside, ring gear, between electric welding wheel and silk screen tube, connection strap 9 in direction pressure holding perpendicular to the silk screen tube, take turns 8 corresponding positions in the medial surface of silk screen tube and electric welding and be provided with silk pressing wheel 10, the middle part of silk pressing wheel 10 is enclosed within the axle of axle bed 2 and goes up (silk pressing wheel 10 rotate synchronously with silk screen tube 3), and axle bed 2 is fixed on the fixed axis 1; At the cylindrical top and the tangent place of silk screen tube of silk pressing wheel 10, silk pressing wheel 10 is pressed into bank groove location in the teeth groove with silk screen.

During welding, electric welding wheel 8 is pressed to connection strap 9 the silk screen welding downwards, and silk pressing wheel 10 upwards is pressed into silk screen bank groove location welding in the teeth groove of ring gear, the pointwise welding that bar 9 and silk screen 3 produce circumference because the rotating band of silk screen tube 3 is dynamically connected;

One wire dish 11 (end of silk screen tube is contained on the circumference of wire dish) is housed in the end of silk screen tube 3, the wire dish on one side with 3 rotations of silk screen tube on one side in that (the wire dish is located on the support on the slide rail, prop up and be erected at movable sliding block, slide block can move along slide rail), in the promotion lower edge axially-movable of screw mandrel, finished connection strap and silk screen tube curl is welded into the tubular screen cloth.The wire distance that changes the wire dish can realize the welding of square hole net, slotted hole net, bar seam net etc.The section of described teeth groove is circular, trapezoidal or triangle.

The present invention can be used for Chinese patent application number: 201020120719.6 (welding device of stainless steel screen, the applyings date: 20100223).
