A pressing device

Abstract

The invention discloses a pin pressing device, relates to the field of pin pressing, and aims to solve the problem that the pin pressing efficiency is low due to manual pin pressing during traditionalproduct pin pressing. The invention provides the technical scheme point that the pin pressing device comprises a base for placing a cylinder, wherein multiple support rods are uniformly distributed along the edge of the base; a placement plate is fixedly arranged at one ends, far away from the base, of the multiple support rods; a telescopic rod for pin pressing is arranged on one surface, far away from the base, of the placement plate in a telescoping way; a drive device for driving the telescopic rod to stretch out and draw back is arranged on the placement plate; a pressing and contactinghead is arranged at one end, close to the cylinder, of the telescopic rod; a fixing device for clamping the pin is arranged on the pressing and contacting head; and a positioning device for fixing theposition of the cylinder is arranged on the support rods. The pin pressing device provided by the invention achieves an effect on improving the pin pressing efficiency.

Description

technical field [0001] The invention relates to the technical field of pin pressing, in particular to a pin pressing device. Background technique [0002] Pins are generally used to connect, lock parts or for assembly positioning, and can also be used as parts of safety devices. The cylindrical pin is fixed in the hole by interference, and is used to fix parts, transmit power, or as a positioning member. [0003] refer to figure 1 with figure 2 , is an existing pin joint product, including a long cylinder 1, one end of the cylinder 1 is welded with a long connecting plate 11, the connecting plate 11 is provided with a fixing hole 12, and the side of the connecting plate 11 away from the cylinder 1 is covered Fixing plate 13, the position corresponding to fixing hole 12 on the fixing plate 13 offers positioning hole 14, then pin 15 is inserted in fixing hole 12 and positioning hole 14, by the interference fit of pin 15 and fixing hole 12 and positioning hole 14 will The ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the existing fixing plate is manually installed, and the pin is manually pressed into the fixing hole and the positioning hole through a hammer. First, the active force exerted by the manual pressing of the pin is always limited, resulting in The personnel have to repeatedly press the pins repeatedly, which greatly reduces the efficiency of the pinning; secondly, the repeated pressing of the pins many times, because the force applied to the pins and the point of application are different each time, it will cause the concentricity of the pins and the fixing holes to be different. Deviation occurs; it is more likely that due to repeated pressing of the pin, fatigue damage will occur on one end of the pin, and the diameter of the knocked end of the pin will become larger, which will eventually cause the pin to be unable to be pressed into the fixing hole, thereby further reducing the pin pressing efficiency. effect
