Embodiment Construction
[0038] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0039] In the present invention, unless stated to the contrary, the used orientation words such as "up, down, front, and back" usually refer to the relative positional relationship of the upper tank body in the use state of the pump truck.
[0040] The present invention provides a method for manufacturing an upper box of a pump truck, wherein the method for manufacturing an upper box of a pump truck includes:
[0041] S1. Process the front web 1, the rear web 2, the middle partition 3, the upper cover plate 4 and the bushing 9, and the front web 1 and the rear web 2 are provided with a fixed bushing 9 The installation hole 5, the inner diameter of the installat...

The invention relates to the field of component manufacturing of pump trucks, and discloses a method for manufacturing an upper box of a pump truck chassis, comprising: processing a front web (1), a rear web (2), and a middle partition (3) , the upper cover plate (4) and the axle sleeve (9), the front web (1) and the rear web (2) are provided with mounting holes (5), and the inner diameter of the mounting hole (5) is compared with that of the axle sleeve (9 ) has a machining allowance; locate and assemble the front web (1), rear web (2), middle partition (3), upper cover (4), and then install it on the chassis (8) ; Install the bushing (9) in the mounting hole (5). Through the above technical scheme, since the shaft sleeve itself has a relatively large wall thickness, during the process of installing the shaft sleeve on the front web and the rear web, the deformation of the inner hole of the shaft sleeve under external effects can be avoided, and better To ensure the accuracy of the position of the inner hole of the shaft sleeve, that is, to ensure that the relative positions of the parts installed on the shaft sleeve are more accurate.
Description
technical field [0001] The invention relates to the manufacture of components of a pump truck, in particular to a method for manufacturing an upper box of a pump truck. Background technique [0002] The underframe of the concrete pump truck consists of an upper box and a lower box that cross in an X shape. The two ends of the lower box and the upper box are respectively equipped with telescopic outriggers. Board, upper cover plate and so on. In order to ensure flexible telescopic movement of the telescopic outriggers in the upper box of the underframe, the production of the tugboat installation holes on the front and rear webs is very critical. The distance between the tugboat installation holes and the middle partition and the center of the tugboat installation holes must be strictly guaranteed during fabrication. The parallelism between the line and the middle partition can ensure that the telescopic outriggers installed on the upper box can move normally without interfer...
