Abstract

PURPOSE:To reduce a size of a tool so as to facilitate operation by forming an oil chamber inside a speed reducer case and forming an oil tank while using a space in the speed reducer case outer circumference so as to directly connects the oil tank to the oil chamber. CONSTITUTION:When a handle part 16 is gripped and a trigger 18 is pressed, a switch 17 is operated, a motor 6 is actuated, a slanting plate 29 is rotated via a speed reducer 4, and then, a pair of plungers 25 are alternately reciprocated so as to serve as a pump. In this way, hydraulic oil inside an oil chamber 5 arranged inside a speed reducer case 3 is passed through a filter while receiving supply of hydraulic oil from an oil tank 7, which is constructed by covering the speed reducer case 3 by an elastic cover 7a, so as to be fed to the inside of a cylinder chamber 20 via an intake valve and a discharge valve, increases a pressure, and drives a piston 21 forward against the force of a return spring 22. Therefore, no special space is required for the oil tank.

However, in the crimping tool 41 of FIG. 5, the oil tank 46 portion is the handle portion 4
Since it is provided so as to project from the tool body 44 along with 5, the position of the handle portion 45 cannot be arbitrarily set so as to take the center of gravity of the tool, the weight balance is poor, and, for example, the working area is narrow. There is a problem in operability, such as when the operation of the distribution board is obstructed by the protruding oil tank 46. Further, in this tool, if the oil supply port is integrally provided in the oil tank 46, it will be difficult to prevent the oil supply plug from coming off. Therefore, the oil supply plug 48 of the oil tank 46 is the tool body to which the oil tank 46 is connected. Four
It is attached to the upper part of 4 by screwing and is connected to the oil tank 46 via the tool body 44, and a sealing measure such as an O-ring is required.

As is apparent from the above description, according to the present invention, an oil chamber is formed in the reduction gear case, and the space around the reduction gear case is used so as to communicate directly with this oil chamber. Since the oil tank is formed by using the oil tank, it is not necessary to secure a unique space for the oil tank as in the past, and it has a substantially straight and compact shape excluding the handle part, making it easy to operate in a narrow work area. Further, the convenience is improved, and the handle portion can be arranged at an appropriate position in consideration of the weight balance of the tool, so that the operability is improved and the workability of the tool is improved. Further, since the elastic material cover between the mounting portions on the outer periphery of the oil tank is enlarged so as to bulge outward, the effective oil storage amount of the oil tank can be increased and the elasticity of the outer periphery of the oil tank can be increased to increase the hydraulic pump. The effect of being able to reduce the inhalation resistance of is obtained. Still further, according to the present invention,
Since the oil supply port is provided integrally with the elastic material cover on the outer circumference of the oil tank and the oil supply port is projected to the outside of the tool cover, it is possible to directly refuel from the outside, and the effect of improving convenience can be obtained. By forming the tip of the oil filler plug into a threaded portion and screwing it to the reducer case on the inner circumference of the oil tank, it is possible to easily and reliably prevent the oil filler plug from being tightly plugged and prevented from coming off. can get.
