Embodiment Construction

[0022] The moving and feeding device of the cross slide of the present invention will be further described in detail with reference to the drawings and embodiments.

[0023] A cross slide moving and feeding device. The device adopts a roller screw drive. It is composed of a cross slide and a feed mechanism (ball screw pair and rolling guide). The cross slide adopts a casting structure with straight balls on both sides. The guide rail and the feeding mechanism in the middle are driven by a ball screw pair, which can achieve stable transmission and high guiding accuracy, thereby ensuring the relative position accuracy of each component. The bottom of the sliding seat is equipped with a sliding block and a nut, which can move longitudinally on the base.

[0024] figure 1 The outline structure of the sliding seat moving mechanism of the present invention is given. The figure shows that the upper part of the sliding seat 5 is equipped with a rolling guide rail 2 and a ball screw 3 trans...

Abstract

The invention discloses a movable feeding device for a cross slide seat, and belongs to the field of advanced manufacturing and equipment. The movable feeding device is used for drilling and end surface machining in a vehicle body machining process for small-batch vehicle production. The invention discloses a ball-screw transmission mechanism with stable running and a rolling guide rail mechanismwith high guide accuracy and bearing capacity. The cross slide seat is of a casting structure, and a ball-screw-nut transmission mechanism is a transmission device with mutually-converted rotary movement and rectilinear movement. The device is low in friction loss, high in transmission efficiency, stable in running, low in friction force, high in sensitivity, and free from a creeping phenomenon ata low speed. A guide rail is in the form of a rolling guide rail, and rolling friction is formed between the two guide rail working surfaces of the rolling guide rail, and realized by rolling bodiessuch as a ball and a roller between the guide rail surfaces. The device has the characteristics of being high in automation degree and flexible machining capacity, and economic and applicable.

Description

Technical field [0001] The invention belongs to the field of advanced manufacturing and equipment, and is used for drilling and end face processing in the processing of small batch production of vehicles. According to the structural characteristics of the car body, the dimensional accuracy of the processed parts, the diversity of the products, the production program and other comprehensive factors, the new development and design of the current mainstream advanced technology is adopted. The device is a reliable and stable ball screw transmission mechanism and Rolling guide rail mechanism with high guiding precision and strong bearing capacity. Background technique [0002] At present, the processing methods of car body processing equipment are backward, making this process not only a weak link in the car body production line, but also very out of proportion to the modernization of the overall production line. Therefore, by adopting new technologies and new methods of current proc...
