The nut end of the long screw stem is located on one side of the bearing and can be clamped with the same. A nut is connected with a stem of the long screw stem in a threaded manner, a supporting mechanism is arranged between the nut and the injection molding machine, and can be abutted against the injection molding machine and the nut respectively. The bearing is slowly driven to move by the long screw stem so as to receive relatively smooth and mild drawing force instead of a huge impact broken out all of a sudden, so that deformation of the bearing due to the huge impact can be effectively avoided, the bearing can be used repeatedly, and production cost of enterprises can be reduced.

Description

一种用于装配和拆卸注塑机轴承的机构 A mechanism assembly and disassembly of the bearing for the injection molding machine

技术领域 FIELD

[0001] 本发明涉及一种注塑机辅助机构,特别是一种用于装配和拆卸注塑机轴承的机构。 [0001] The present invention relates to an injection molding machine assist mechanism, in particular the mechanism for injection molding machines for the assembly and disassembly of the bearing.

背景技术 Background technique

[0002] 众所周知,注塑机床身上的轴承与床身之间的配合是过盈配合,而且轴承是由黄铜制成的高精度配件,其硬度相对较低。 [0002] is well known, the fit between the bearing and the bed of the injection molding machine body is an interference fit, and precision bearings are made of brass fittings, relatively low hardness.

[0003]目前,工人将轴承装配在注塑机床身上或将轴承从注塑机床身上拆卸下来的主要做法如下: [0003] Currently, the main approaches to workers bearing assembly in the injection molding machine body or the bearing body detached from the injection molding machine down as follows:

参照图1 (图中箭头的方向表示力的撞击方向),采用一根直径与轴承I的外径相同的铜棒7,铜棒7的一端与轴承I对正且相抵接,然后再通过外力敲打铜棒7的另一端,从而将轴承I撞击进注塑机床身4的安装孔内或将轴承I从注塑机床身4的安装孔中挤出,从而完成轴承I的安装或拆卸。 Referring to FIG. 1 (direction of the arrow indicates the direction of impact force FIG.), Using the same outer diameter as a diameter of the bearing 7 I of copper, copper I bearing 7 and an end of the positive and abuts, by an external force and then tapping the other end of the copper rod 7, so that the injection molding machine into the strike I bearing mounting hole 4 of the body or the bearing body I extruded from the injection molding machine in the mounting hole 4, thereby completing the installation or removal of the bearing I. 由于采用此种通过冲击力的安装或拆卸方法没有相应的保护装置,而且轴承I本身的硬度相对较低,因此轴承I经冲击力的作用后,变形严重,甚至损坏报废,使得轴承I重复利用率低,增加了企业的生产成本,同时还增大了工人的劳动强度。 Since the use of such a method is not attached or detached by the impact of the respective protection means, and relatively low hardness of the bearing itself, I, I thus acting via the rear bearing impact, severe deformation and even damage to the scrap, such that the bearing reuse I rate, increased production costs, while also increasing the labor intensity.

发明内容 SUMMARY

[0004] 为了解决上述问题,本发明的目的在于提供一种结构简单,又可以有效减轻轴承装配或拆卸时的形变的机构。 [0004] In order to solve the above problems, an object of the present invention is to provide a simple structure, and can effectively reduce deformation mechanism during assembly or disassembly of the bearing.

[0005] 本发明为解决其技术问题而采用的技术方案是: [0005] aspect of the invention to solve the technical problem is that:

一种用于装配和拆卸注塑机轴承的机构,包括活动穿装在轴承内的长螺杆,所述长螺杆的螺帽端部位于轴承的一侧且能够与该轴承相卡接,该长螺杆的杆身上螺纹连接有螺母,所述螺母与注塑机床身之间设置有支撑机构,所述支撑机构能够分别与注塑机床身和螺母相抵接。 A mechanism assembly and disassembly of a bearing for an injection molding machine, comprising a screw length reeved activity within the bearing, the long end of the nut screw is located on one side of the bearing and capable of bearing contact with the card with the long screw the shank screwed a nut, a support mechanism provided between the nut and the body of the injection molding machine, said support means of the injection machine can each abut the body and a nut.

[0006] 作为上述技术方案的改进,所述支撑机构包括两块其一端均与注塑机床身相抵接的支撑块,所述两块支撑块的另一端之间固定设置有拉码,所述长螺杆从拉码中穿过,且所述拉码位于注塑机床身和螺母之间。 [0006] As an improvement of the above technical solution, said support means comprises a support block are two end thereof abuts with the injection molding machine body, the code is fixedly provided between the other end of the pull two support blocks, the length screw pull through the code, and the code is located between the pull injection molding machine body and the nut.

[0007] 作为上述技术方案的进一步改进,所述拉码左右两端分别通过两枚螺栓固定安装在两块支撑块上。 [0007] As a further improvement to the foregoing technical solution, the code pull left and right ends fixedly mounted respectively on the two bolts two support blocks.

[0008] 进一步,所述支撑机构为一个活动套装在长螺杆上的中空套筒,该中空套筒的两端能够分别与注塑机床身和螺母相抵接。 [0008] Further, the support means is a hollow sleeve in the active set screw length, both ends of the hollow sleeve of the injection machine can each abut the body and a nut.

[0009] 再进一步,所述长螺杆的螺帽端部与轴承之间设置有防止轴承被损坏的保护垫,所述保护垫套装在长螺杆上。 [0009] Still further, the screw length is provided between the nut and the bearing end portion to prevent the bearing from being damaged protective pad, the protective pad is fitted over the screw length.

[0010] 本发明的有益效果是:由于本发明通过设置一个能够与轴承相卡接的长螺杆,长螺杆上螺纹连接有螺母,螺母与注塑机床身之间设置有一个支撑机构,当不断地旋转螺母时,螺母因受到支撑机构的支撑作用而固定不动,使得长螺杆的螺帽端部渐渐地向螺母靠近,从而拉动与其相卡接的轴承缓慢地向前移动,因此轴承可以缓慢地被拉进注塑机床身的安装孔内或从注塑机床身的安装孔中被拉出,由于轴承受到的是相对平稳、缓和的拉力,而不是突然间爆发的巨大冲击力,可有效避免轴承因受到巨大冲击力而变形的发生,使得轴承可以反复利用,降低企业的生产成本,同时工人也可以通过扳手轻松拧动旋转螺母,不再需要大力敲击铜棒,有助于降低劳动强度。 [0010] Advantageous effects of the invention are: Since the present invention by providing a contact capable of bearing a long screw with the card, the long screw has a threaded connection provided with a support mechanism between the nut, the nut body with the injection molding machine, when continuously when rotation of the nut, the nut is supported by the support mechanism and the role of stationary, so that the length of the screw nut to an end portion of the nut gradually close, thereby pulling movement of the front bearing contact therewith card slowly, so the bearing can be slowly pulled into the injection molding machine body mounting holes or being pulled out from the mounting hole injection molding machine body, since the bearing is subjected to relatively stable, easing tension, rather than a huge impact among the sudden outbreak, which can effectively prevent the bearing due be a huge impact and deformed so that the bearing can be reused, reducing production costs, while workers can easily twist the rotating nut wrench, no longer need to vigorously tap copper rod, help reduce labor intensity.
