Abstract
The invention relates to a pliers actuation assembly (1), pliers and a method of assembling a pliers actuation assembly (1). According to the invention, a locking pawl (85) has protrusions (89), a spring (86) has protrusions (92) and/or pulling bars (16, 17) have protrusions (14, 15) which are received in accommodations (90, 93, 12, 13) of hand lever plates (64, 65, 66, 67) in a joining direction vertical to the pivoting plane of hand levers (2, 3). The inventive design facilitates assembly of the pliers actuation assembly (1), while also enabling an at least partially automated assembly.
Claims17
A method of assembling a pliers actuation assembly group designed and configured to be coupled to a pliers head to form pliers in such a way that a stroke of die halves of the pliers head can be brought about by means of manual actuation of the pliers actuation assembly group, the pliers actuation assembly group comprising
- two hand levers, at least one of the hand levers having a first hand lever plate and a second hand lever plate which are rigidly connected to one another,
- a pivot bolt via which the hand levers are pivotably connected to one another,
- a mounting element,
- wherein the mounting element has a first and second shoulder and a first and second protrusion protruding from the first and second shoulder,
- the method comprising the following method steps:
- a) joining the mounting element in a joining direction with the first hand lever plate, whereby the first protrusion of the mounting element enters into a first accommodation of the first hand lever plate and the first shoulder of the mounting element comes into contact with the first hand lever plate in the joining direction or is arranged adjacent thereto, and
- b) joining the second hand lever plate in the joining direction onto the mounting element, whereby the second protrusion of the mounting element enters into a second accommodation of the second hand lever plate and the second shoulder of the mounting element comes into contact with the second hand lever plate or is arranged adjacent thereto, and
- c) fixing a relative position of the first and second hand lever plate, whereby the first and second shoulder of the mounting element are trapped between the first and second hand lever plate so that the mounting element is secured against disassembly from the first and second accommodation of the first and second hand lever plate.

- b) a pivot bolt via which the hand levers are pivotably connected to one another,
- c) a mounting element,
- d) the mounting element having a first and second shoulder and a first and second protrusion protruding from the first and second shoulder,
- e) the mounting element been joined with the first hand lever plate in a joining direction so that the first protrusion of the mounting element extends into a first accommodation of the first hand lever plate and the first shoulder of the mounting element contacts the first hand lever plate in the joining direction or is arranged adjacent thereto,
- f) the second hand lever plate being joined in the joining direction onto the mounting element so that the second protrusion of the mounting element extends into a second accommodation of the second hand lever plate and the second shoulder of the mounting element contacts the second hand lever plate or is arranged adjacent thereto,
- g) a relative position of the first and second hand lever plate being fixed to each other,
- h) the first and second shoulder of the mounting element being trapped between the first and second hand lever plate so that the mounting element is secured against disassembly from the first and second accommodation of the first and second hand lever plate.
