Embodiment Construction

[0008] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0009] The mechanism of the ratchet wheel for slider adjustment has a transmission shaft 5. Set the adjustment wheel 1 on the outer circle of the transmission shaft 5. When assembling, pay attention to make the grooves on the inner and outer circles of the two face each other, and install the spring piece 7 on the adjustment wheel. 1 position, and at the same time, install the brake pawl 9 in the groove corresponding to the adjustment wheel 1 and the transmission shaft 5, and install two flat washers 2 from both sides to the inner hole of the adjustment wheel 1 and the outer surface of the transmission shaft 5. On the top of the circle, the bearing 3 should be installed in place during installation. At this time, install the sealing ring 6 in the sealing ring groove of the bearing cover 4, and install and fix the two sides of the bearing cover 4 adjusting wheel 1 o...

Abstract

The invention discloses a ratchet wheel mechanism for slide adjusting. An adjusting wheel is sleeved on an excircle of a transmission shaft, grooves on an inner circle of the adjusting wheel and the excircle of the transmission shaft need to be aligned at each other when the adjusting wheel is sleeved on the excircle of the transmission shaft, then a spring sheet is installed at the position of the adjusting wheel, simultaneously braking key claws are installed in the grooves corresponding to the adjusting wheel and the transmission shaft, two pieces of flat washers are installed on inner round holes of the adjusting wheel and the excircle of the transmission shaft from two sides, and the bearing needs to be installed in place in installation. Then, an upper sealing ring is installed in a sealing ring groove of a bearing cover, and two sides of the adjusting wheel of the bearing cover are fixedly installed on the adjusting wheel through a counter sunk screw.

Description

technical field [0001] The invention relates to a ratchet mechanism, in particular to a ratchet mechanism for sliding block adjustment. It belongs to the technical field of presses. Background technique [0002] In some existing presses, in order to facilitate the manual adjustment of the working position of the slider, a one-way transmission ratchet mechanism is often set on the high-speed transmission shaft of the transmission system. Although the structure of the ratchet with this structure is simple and easy to manufacture, but It is sometimes difficult to combine between the roller and the wedge-shaped groove. At the same time, the force is transmitted by friction, which has the disadvantages of small and slow transmission. Contents of the invention [0003] The purpose of the present invention is to provide a ratchet mechanism for slider adjustment, which overcomes the difficulty in combining the structure between the roller and the wedge-shaped groove in the existi...
