Embodiment 1

[0077] The present invention provides a positioning and clamping device for construction machinery shells, comprising a positioning seat 1, the positioning seat 1 is preferably a cylindrical positioning seat 1, and the positioning seat 1 has at least two non-overlapping positioning surfaces 30 (the positioning surfaces can also be The positioning surfaces 30 do not overlap each other, and there is a certain angle α between two adjacent positioning surfaces 30, and α is preferably 60 to 120 degrees; or, the positioning seat 1 has several sets of positioning surfaces 30 Each group of positioning surfaces 30 includes two positioning surfaces 30 parallel to each other and spaced apart; at least two positioning surfaces 30 are provided with clamps, which are used to position and clamp workpieces 17, and multiple workpieces 17 can be positioned well at the same time Clamped on the positioning seat 1, the workpiece 17 clamped between the positioning surfaces 30 does not interfere with...

Embodiment 2

[0111] As a preferred solution, a construction machinery casing processing system includes the construction machinery casing positioning and clamping device as described in Embodiment 1, which is different from Embodiment 1 in that: it also includes a workbench, and the workbench is provided with In the rotary drive part, the positioning seat 1 is connected to the power output end of the rotary drive part. Driven by the rotary drive part, the positioning seat 1 and the fixture can be rotated, thereby driving the workpiece 17 to rotate, and then the positioning and clamping device can also be fixed on the On a common three-axis horizontal machining center, the rotary drive unit is used to replace the rotary table 18, so as to realize the functions of the four-axis horizontal machining center in the first embodiment.

Embodiment 3

[0113] As a preferred solution, the construction machinery housing positioning and clamping device can also be used on the vertical machining center, and its difference from Embodiment 1 or Embodiment 2 is:

[0114] The notches 12 of the support rings 16 on both sides of the workpiece 17 are oppositely arranged.

Abstract

The invention discloses an engineering machinery shell positioning and clamping device and method and a processing system. The device comprises a positioning seat which is provided with at least two positioning faces not overlapped, the positioning faces are not overlapped, and certain included angles are formed among the positioning faces; or, the positioning seat is provided with a plurality ofpositioning faces, and each positioning face comprises two parallel positioning faces which are arranged in a spaced manner; clamps are arranged on the at least two positioning faces, the clamps are used for positioning and clamping a plurality of workpieces and can position and clamp the workpieces well on the positioning seat simultaneously, and the workpieces clamped among the positioning facesdo not interfere one another. The engineering machinery shell positioning and clamping device disclosed by the invention achieves a technical effect that the workpieces are clamped at one time and multiple steps are combined for processing, so that the workpiece clamping number of times is reduced, and the production efficiency is improved greatly while the workpiece processing precision is guaranteed.

Description

technical field [0001] The invention relates to a positioning and clamping device, a method and a processing system for an engineering machinery shell. Background technique [0002] Shell workpieces, taking construction machinery shells as an example, are important parts in construction machinery systems. Generally speaking, their materials are relatively hard and require high precision. Without good tooling, it is difficult to guarantee Product processing accuracy. [0003] In addition, due to the complex shape of the workpiece and the variable processing position, the entire processing process is very complicated. Taking the gearbox support flange as an example, the content to be processed generally includes end surface features and peripheral surface features. The processing methods generally include: [0004] 1. First, use a lathe to turn the lower end surface and inner cavity of the workpiece. [0005] 2. Then the workpiece is turned over, and the upper end surface of...
