Description
技术领域 technical field
本实用新型属机械领域，尤其涉及一种轴销装置。 The utility model belongs to the field of machinery, in particular to a shaft pin device.
背景技术 Background technique
现有技术中对轴销装置实现锁紧是通过在轴销本体底部焊接锁片来实现，锁片起到固定轴销本体的作用。这样的结构在使用中有以下方面缺陷：1、该轴销装置加工成本高，轴销在生产加工时必须热处理使轴销本体硬化以适应使用要求，但锁片作为固定配件并不需要这一加工工序，但由于轴销本体与锁片焊接在一起，因此在加工时要额外增加能耗，提高生产成本。2、生产工艺复杂，将轴销本体与锁片焊接固定为一体，这一焊接工序本身就较为复杂，不利于提高生产效率。3、易产生浪费，当轴销本体或锁片出现磨损或其他影响使用的情况，整个轴销装置也随之报废，不利于节约生产。 In the prior art, the locking of the shaft pin device is realized by welding the locking piece at the bottom of the shaft pin body, and the locking piece plays the role of fixing the shaft pin body. Such a structure has the following disadvantages in use: 1. The shaft pin device has high processing costs, and the shaft pin must be heat-treated during production and processing to harden the shaft pin body to meet the requirements of use, but the lock plate does not need this as a fixed accessory. Processing procedure, but because the shaft pin body and the locking piece are welded together, additional energy consumption is required during processing, which increases production costs. 2. The production process is complex, and the shaft pin body and the locking plate are welded and fixed as one. This welding process itself is relatively complicated, which is not conducive to improving production efficiency. 3. It is easy to produce waste. When the shaft pin body or the lock piece wears or other conditions that affect the use, the entire shaft pin device is also scrapped, which is not conducive to saving production.
发明内容： Invention content:
本实用新型提供一种结构合理，拆卸简单，生产成本低廉的轴销装置。本实用新型采取的技术方案为：一种轴销装置，包括轴销本体、锁片和螺栓，所述轴销本体底部设有凸台，所述凸台的底面开设有螺孔，所述锁片上开设有与凸台对应的槽口，所述凸台与槽口卡合后，可使轴销本体不发生转动运动，所述螺栓可通过所述槽口旋紧于螺孔内将所述轴销本体与锁片固定。 The utility model provides a shaft pin device with reasonable structure, simple disassembly and low production cost. The technical solution adopted by the utility model is: a shaft pin device, including a shaft pin body, a lock piece and a bolt, a boss is provided at the bottom of the shaft pin body, a screw hole is opened on the bottom surface of the boss, and the lock There is a notch corresponding to the boss on the sheet. After the boss is engaged with the notch, the shaft pin body will not rotate. The bolt can be tightened in the screw hole through the notch to tighten the bolt. The shaft pin body is fixed with the locking plate.
作为一种实施方式，本实用新型一种轴销装置，所述凸台（4）截面可以是多边形。 As an embodiment, the utility model is a shaft pin device, and the section of the boss (4) may be polygonal.
作为一种实施方式，本实用新型一种轴销装置，所述凸台（4）截面可以是半圆形。 As an embodiment, the utility model relates to a shaft pin device, and the section of the boss (4) may be semicircular.
本实用新型的创新在于采取独特的组装方式而非焊接方式将轴销本体与锁片固定在一起，为实现这一技术目的必须解决两个问题：1、轴销本体能与锁片固定不发生转动和轴向窜动，2、轴销本体不会从锁片上脱落。解决第一个问题的手段是在轴销本体底部设凸台，并在锁片上开设与凸台对应的槽口，为保证轴销本体不发生转动可以把凸台形状设置成椭圆形、多边形、半圆形以及除圆形外的任何形状，如此即可确保轴销本体不会因外力作用发生转动。解决第二个问题的技术手段是通过在轴销本体底部凸台的底面开设螺孔，配合螺栓将锁片与轴销本体进行固定，确保轴销本体不会发生脱落的同时也不会发生轴向运动。 The innovation of the utility model lies in adopting a unique assembly method rather than a welding method to fix the shaft pin body and the locking plate together. To achieve this technical purpose, two problems must be solved: 1. The shaft pin body can be fixed with the locking plate without occurrence Rotation and axial movement, 2. The shaft pin body will not fall off from the locking piece. The means to solve the first problem is to set a boss at the bottom of the shaft pin body, and set a notch corresponding to the boss on the locking plate. In order to ensure that the shaft pin body does not rotate, the shape of the boss can be set to ellipse, polygon, Semicircle and any shape except circle, so as to ensure that the shaft pin body will not rotate due to external force. The technical means to solve the second problem is to open a screw hole on the bottom surface of the boss at the bottom of the shaft pin body, and cooperate with bolts to fix the locking plate and the shaft pin body, so as to ensure that the shaft pin body will not fall off and the shaft will not occur. to the movement.
上述技术方案，使生产和安装工艺都更为简单，提高生产效率；可以先对轴销本体进行热处理后再装配锁片，降低能耗、节约加工成本；当轴销本体或锁片出现使用故障时，可拆卸进行拆卸替换，节省材料资源。 The above technical scheme makes the production and installation process simpler and improves production efficiency; the shaft pin body can be heat-treated first and then the lock piece can be assembled to reduce energy consumption and save processing costs; when the shaft pin body or the lock piece fails to use When used, it can be disassembled for disassembly and replacement, saving material resources.
