Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of zipper, concretely relates to a bidirectional durable slider tool seat. BACKGROUND

[0002] As one of the common tools on clothes, the zipper is widely used in various clothes. In order to meet the demand of the zipper, various automatic equipment for assembling the zipper appears in the market. Among them, in the automatic equipment for assembling the slider, the slider needs to be installed on the corresponding tool seat. In order to facilitate the assembly and disassembly of the slider, most of the automatic equipment for assembling the slider is positioned on the tool seat by the plug-in mode. However, the plug-in mode will cause the tool seat to be frequently rubbed with the slider, which will easily cause the tool seat to be worn after a long time of use. Especially in the process of assembly, the riveting process will cause the tool seat to be further worn.

[0003] In the prior art, such as the patent document with the announcement number CN204171917U, a slider clamp is disclosed, which installs the slider in the installation area by the plug-in mode. However, after a long time of use, the installation area is easily worn. When the clamp is used in the automatic equipment with the riveting process, the force applied to the clamp during the riveting will cause the clamp to be further worn, which reduces the service life of the clamp. SUMMARY

[0004] In view of the problems in the prior art, the utility model provides a bidirectional durable slider tool seat. On the one hand, the positioning unit can be used bidirectionally by the positioning parts symmetrically arranged on both sides of the positioning unit, which improves the service life of the positioning unit. On the other hand, the raw material in the avoiding channel is pushed to the dropping groove when the slider is fed, which prevents the raw material from damaging the mounting seat and the positioning unit.

[0005] The utility model is implemented as follows: a bidirectional durable slider tool seat; the tool seat comprises a mounting seat, the mounting seat is provided with a detachable connecting positioning unit for positioning the slider; the positioning unit comprises positioning parts symmetrically arranged at both ends, the positioning unit can be used bidirectionally by the positioning parts symmetrically arranged at both ends of the positioning unit, which improves the service life of the positioning unit and makes the positioning unit more durable.

[0006] The positioning unit comprises a first supporting part and a second supporting part symmetrically arranged on both sides of the first supporting part. When the puller is connected with the positioning unit, the first supporting part extends into the puller and simultaneously abuts against the top plate and the bottom plate of the puller. The side plate of the puller is provided with a gap for the chain belt to pass through, which divides the side plate into an upper side plate and a lower side plate. The second supporting part passes through the gap and simultaneously abuts against the upper side plate and the lower side plate. By supporting the top plate, the bottom plate and the side plate of the puller when riveting, the first supporting part and the second supporting part prevent the puller from being suspended inside when riveting, thereby reducing the risk of deformation of the puller when riveting and improving the reliability of the positioning unit.

[0007] The mounting seat is further provided with a material dropping groove. When the positioning unit is connected with the mounting seat, an avoiding channel is formed between the second supporting part and the mounting seat. The material dropping groove is arranged below the positioning unit and communicates with the avoiding channel. Due to the tolerance of the size of the puller, the material on the puller is ground off when the puller is connected with the positioning unit. After a long period of use, the material is easily accumulated in the avoiding channel, which increases the risk of wear of the positioning unit and the mounting seat. The material dropping groove pushes the material in the avoiding channel to the material dropping groove when the puller is connected with the positioning unit, so that the material is discharged from the material dropping groove, thereby preventing the material from wearing the mounting seat and the positioning unit and further improving the service life of the mounting seat and the positioning unit.

[0008] Preferably, the mounting seat is provided with a first positioning groove which is matched with the positioning unit. When the positioning unit is mounted on the mounting seat, one end of the positioning unit is embedded in the first positioning groove. The first positioning groove is used for preliminary positioning of the positioning unit. By embedding one end of the positioning unit in the first positioning groove, the freedom of left-right movement of the positioning unit is limited, which prevents the positioning unit from moving left and right and improves the installation accuracy of the positioning unit.

[0009] Specifically, the mounting seat is further provided with a second positioning groove, and the extension direction of the second positioning groove is perpendicular to the extension direction of the first positioning groove. The positioning unit is provided with a first positioning boss matched with the second positioning groove. When the positioning unit is mounted on the mounting seat, the first positioning boss is embedded in the second positioning groove. The second positioning groove is used for secondary positioning of the positioning unit. By embedding the first positioning boss in the second positioning groove, the freedom of forward-backward movement of the positioning unit is limited, which prevents the positioning unit from moving forward and backward. In cooperation with the first positioning groove, the positioning unit is relatively fixed with the mounting seat, which further improves the installation accuracy of the positioning unit.

[0010] Preferably, the positioning unit is also symmetrically provided with a limiting groove at both ends, and the puller is in abutment with the limiting groove when the puller is installed on the positioning unit. The limiting groove is used to limit the installation position of the puller on the positioning unit, prevent the puller from exceeding the riveting range, and improve the reliability of the positioning unit.

[0011] Specifically, the limiting groove gradually decreases from the end to the middle of the positioning unit, so that the cross section of the limiting groove is V-shaped. The V-shaped limiting groove has a centering property, and when the puller is in abutment with the limiting groove, the limiting groove can guide the puller to be centered with the positioning unit, further improving the positioning effect of the positioning unit.

[0012] Preferably, the material dropping groove is gradually inclined from top to bottom and communicates with the outside through the side wall of the mounting seat. Since the mounting seat needs to bear the riveting pressure during the riveting process of the puller, the inclined material dropping groove can reduce the hollow area of the mounting seat, improve the bearing capacity of the mounting seat, and thus improve the service life of the mounting seat, making the mounting seat more durable.

[0013] Preferably, the bottom of the mounting seat is provided with a second positioning boss protruding downward, and the transfer mechanism is provided with a third positioning groove matched with the second positioning boss, and the second positioning boss is embedded in the third positioning groove when the mounting seat is installed on the transfer mechanism. The second positioning boss is used for positioning when the mounting seat is installed, improving the positioning accuracy and installation convenience of the mounting seat.

[0014] Preferably, the middle of the positioning unit is provided with a mounting hole, and a threaded fastener is used to fix the positioning unit to the mounting seat through the mounting hole. Since the positioning unit has two ends, the threaded fastener is used to fix the positioning unit to the mounting seat, and when the positioning unit needs to be replaced with the other end, the threaded fastener can be assembled and disassembled to realize the replacement of the positioning unit, improving the convenience of the positioning unit.

[0015] Preferably, the mounting seat is T-shaped, including a bearing part extending along the extension direction of the positioning unit, and a fixing part extending vertically along the extension direction of the bearing part, and a plurality of fixing holes are arranged on the fixing part. Since the mounting seat will produce a overturning moment when subjected to the force of riveting, and thus additional load will be generated on the fixing member for fixing the mounting seat, by arranging a plurality of fixing holes, the number of fixing members is increased, and thus the load increase of a single fixing member during riveting can be reduced, improving the service life of the fixing member, and thus improving the service life of the mounting seat, making the mounting seat more durable.

[0016] Preferably, the mounting seat and the positioning unit are made of metal wear-resistant material, since the puller will rub against the mounting seat and the positioning unit during installation and disassembly, the mounting seat and the positioning unit made of metal wear-resistant material improve the wear resistance of the mounting seat and the positioning unit, can reduce the wear caused by the friction of the puller, and further make the mounting seat and the positioning unit more durable.
