Description

Yarn gripper for gripper shuttle loom

Technical field

This utility model relates to gripper shuttle loom, the yarn gripper of such as Axminster gripper shuttle loom, It includes two clamping parts interconnected, and these two clamping parts are relative to each other removable for folder Tightly, first described clamping part includes that at least two guides and caves in, and second described clamping part Including the guiding tongue that at least two is corresponding, described guiding tongue is prolonged towards described first clamping part Stretch, guide depression and guide tongue and be located so that when clamping part is moved relative to guide recessed Fall into receive and guide tongue sliding motion wherein.

This utility model is additionally related to the method for manufacturing this yarn gripper.

Background technology

For the yarn gripper of Axminster gripper shuttle loom such as at GB 1 344 979A, EP 1 696 Described in 059A2 and EP 1 365 052B1.

In GB 1 344 979A and EP 1696 059A2, yarn gripper clamping part is by means of hinge Joint is articulated and connected, and is provided with corresponding guiding tongue and guides depression, for moving at them During be directed at clamping part.

In EP 1 365 052B1, yarn gripper clamping part interconnects by means of middle elastic members and sets It is equipped with staggered projection, for being directed at clamping part in they motor processs.But these projections with such as Guiding tongue in the yarn gripper of GB 1 344 979A and EP 1696 059A2 and guiding depression phase Than being not particularly suitable for being directed at clamping part.

But, this guiding tongue is the relatively weak part of yarn gripper, and this relatively weak part bears the portion of abrasion Divide and may bend or fracture.When guiding tongue abrasion, the function rapid decay of yarn gripper, especially When being a guiding tongue fracture wherein, another itself cannot ensure the most right of clamping part Accurate.

Utility model content

What the purpose of this utility model was to provide a kind of such yarn gripper more prevents fault version.

This purpose is by providing a kind of for gripper shuttle loom, such as Axminster gripper shuttle loom Yarn gripper realizes, and described yarn gripper includes two clamping parts interconnected, said two clamping section Dividing and relative to each other may move, for clamping, first described clamping part includes that at least two is led Draw depression, and second described clamping part includes the guiding tongue that at least two is corresponding, this guiding Tongue highlights towards described first clamping part, and described guiding depression and guiding tongue are located so that When clamping part is moved relative to, the described depression that guides receives guiding tongue sliding motion wherein, And wherein, described second clamping part includes constituting the tongue body of described guiding tongue and described tongue Body utilizes the main body that seam is fixed thereon.

This seam forms visible line, and this visible line is at main body and tongue body on the specific area Formed during connection.They such as can couple by means of brazing or laser welding or glue bonding etc..This Can to seam add additional materials or without additional materials in the case of realize.

This seam forms the weak part of clamping part now.When guiding tongue fracture, the most whole Individual tongue body will rupture and whole yarn gripper is by fault.The function of yarn gripper will the most gradually decline Move back, cause non-optimal work during the longer time period, but will stop suddenly, cause this folder Yarn device prevent fault version.Yarn gripper will be repaired and enable him to task the most again.

Owing to two guide tongues and are connected to main body together as the part of tongue body, seam will compare When tongue is individually connected in main body much longer.By this way, seam is the most fragile so that The time period that the correct operation duration of this yarn gripper is suitable with known yarn gripper.

Originally be embodied in separately fabricated due to tongue, guiding tongue can also be made and be formed as clamping than them Part integral part time higher.

Preferably, include bottom according to the tongue body of yarn gripper of the present utility model, guide tongue Extend bottom this.Then main body is preferably formed with depression, and the bottom of described tongue body is placed on In this depression.By this way, owing to bottom is embedded in main body, the power on tongue body is acted on Main body will be passed to so that the connection between tongue body and main body is higher.

It is even furthermore preferable that then the depression of the bottom of tongue body and main body has corresponding shape Formula.

Two described guiding tongue preferably horizontal expansions on the apparent surface of tongue body so that by Guiding, in the first clamping part entrance, the power acted between tongue in guiding tongue can be at least part of Compensate one another so that these power are less born in the connection between tongue body and main body.

According in the further preferred embodiment of yarn gripper of the present utility model, guiding tongue is to hand over Wrong.The depression that guides in the first clamping part is the most also staggered so that the first clamping part Due to provide wherein depression and the most weakened.

Guide tongue and be further preferably positioned at pile yarns by attached for the end of held clamping part Closely, owing in these ends, being correctly aligned of clamping part is most critical.

In particularly preferred embodiments, the length guiding tongue and guiding depression is selected such that When clamping part is moved relative to, it is recessed that a part for guiding tongue remains at corresponding guiding In falling into.By this way, the clamping part between fully open position and fully closed position is every In individual position, guide tongue is bonded on corresponding guiding in depression at least partially.

According in the particularly preferred embodiment of yarn gripper of the present utility model, clamping part by means of At least one middle elastic members interconnects.This middle elastic members is not easy to mill compared with knuckle joint Damage.

At least one middle elastic members of this embodiment is preferably made up of middle spring band.

Clamping part and the middle elastic members of this embodiment are preferably manufactured from the same material.

First clamping part, main body and the middle elastic members of this embodiment are preferably made as one Part.

The purpose of this utility model is also by providing one for manufacturing for gripper shuttle loom, such as The method of the yarn gripper of Zxminster gripper shuttle loom realizes, and described yarn gripper includes two folders interconnected Tight part, said two clamping part relative to each other may move, for clamping, described first folder Tight part includes that at least two guides depression, and second described clamping part includes that at least two is relative The guiding tongue answered, described guiding tongue highlights towards described first clamping part, and described guiding is caved in It is positioned at described guiding depression reception when described clamping part is moved relative to guiding tongue Described guiding tongue sliding motion wherein, wherein, tongue body is provided with two described tongues, carries Main body, described tongue body has been supplied to utilize seam to be fixed to described main body, in order to form the second clamping section Point.

In ad hoc approach, tongue body is fixed to described main body by means of brazing.

In the ad hoc approach substituted, tongue body is fixed on described main body by means of laser welding.

In the preferred implementation according to method of the present utility model, described main body includes caving in and institute Stating tongue body and include bottom, described guiding tongue extends from described bottom, and by described tongue originally Before body is fixed on described main body, described tongue body is to put bottom it in the depression of described main body Put.

Now as follows by by means of some embodiments according to yarn gripper of the present utility model and method Describe in detail and this utility model is explained in greater detail.The purpose of this description only provides explanation and shows Example, and point out further advantage of the present utility model and feature, and it is new therefore to should not be construed as this practicality The range of application of type or the restriction of patent right defined in the claims.
