Description

A Cartesian Coordinate Robot Horizontal Axis Floating Connection Mechanism

technical field

The utility model relates to a rectangular coordinate robot, in particular to a horizontal axis floating connection mechanism of a rectangular coordinate robot.

Background technique

Cartesian robot is a kind of industrial robot, which can be widely used in industrial fields such as handling, palletizing, sorting, packaging, welding, metal processing, and assembly. It plays a significant role in replacing manual operations, reducing labor costs, improving production efficiency, and stabilizing product quality.

At present, the rectangular coordinate robots on the market are basically in the form of three coordinates, and the XYZ three axes are controlled by different motors, and they are linked together to achieve the purpose of processing and assembly. Existing Cartesian robots mostly use double X-axes, and the two ends of the entire Y-axis (ie, the horizontal axis) are respectively fixed on two slide plates of the X-axis (ie, the vertical axis) to realize movement in the X-direction. However, due to the processing error of the parts and the installation error of the equipment, as well as the inevitable deformation or slight movement of the robot after running for a period of time, the distance between the two X axes changes slightly, so that they are not completely parallel, and then This will cause clamping, noise, friction and other phenomena during the operation of the Y-axis. If the situation is serious, the equipment may be damaged, which will seriously affect the processing and assembly of the product and reduce the production efficiency.

Utility model content

The purpose of the utility model is to provide a horizontal axis floating connection mechanism of a Cartesian coordinate robot that can freely adjust the distance between two horizontal axes.

The purpose of this utility model is achieved through such a technical scheme, a Cartesian coordinate robot horizontal axis floating connection mechanism, including two X axes arranged in parallel and a Y axis connected to two X axes at both ends, on the Y axis A Z-axis with a handle connected to the Y-axis is vertically arranged, and a fixed-end beam and a movable-end beam are respectively arranged on the X-axis, and one end of the Y-axis is connected to the fixed-end beam by a bolt, and the Y The other end of the shaft is connected with the beam at the movable end through a floating connection mechanism.

Wherein, the floating connection mechanism includes a connecting seat, and a connecting rotating shaft passing through the connecting seat is arranged in the connecting seat, and a bearing seat is arranged on the outside of the connecting rotating shaft, and the bearing seat and the connecting seat are connected by bolts. An adapter plate is provided on the lower end surface of the shaft, and the adapter plate is connected to the lower end of the connecting shaft through screws, and rolling bearings I, rolling bearing II, rolling bearing III, rolling bearing IV and bearings are arranged in sequence from bottom to top on the connecting shaft For the pressure sleeve, two linear guide rails are arranged in parallel on the lower end surface of the adapter plate; a pair of sliders are arranged on the upper end surface of the movable end beam, and the linear guide rails are installed on the sliders.

Due to the adoption of the above technical solution, the utility model has the advantages of simple structure and strong reliability. It can freely adjust the lateral connection position between the two X axes, so that the Y axis can move more smoothly in the X direction, reducing the Reduced equipment failure rate, improved product quality and production efficiency.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in further detail, but the utility model is not limited to these implementation modes, and any improvement or substitution on the basic spirit of this embodiment still belongs to the claims of the utility model Scope of protection claimed.

Embodiment 1: As shown in Figure 1, a Cartesian coordinate robot horizontal axis floating connection mechanism, including two X axes 1 arranged in parallel and a Y axis 2 connected to two X axes 1 at both ends, on the Y axis 2 A Z-axis 4 with a gripper 3 connected to the Y-axis 2 is vertically arranged, and a fixed-end crossbeam 5 and a movable-end crossbeam 6 are respectively arranged on the X-axis 1, and one end of the Y-axis 2 is fixed with a bolt. The end beam 5 is connected, and the other end of the Y-axis 2 is connected with the movable end beam 6 through a floating connection mechanism.

Further description, as shown in Figures 2, 3, and 4, the above-mentioned floating connection mechanism includes a connecting seat 7, and a connecting shaft 8 passing through the connecting seat 7 is arranged in the connecting seat 7, and a bearing seat 9 is arranged on the outer sleeve of the connecting rotating shaft 8, and the bearing The seat 9 is connected with the connecting seat 7 by bolts, and an adapter plate 10 is arranged on the lower end surface of the connecting seat 7, and the adapter plate 10 is connected with the lower end of the connecting shaft 8 by screws, and on the connecting shaft 8 Rolling bearing I11, rolling bearing II12, rolling bearing III13, rolling bearing IV14 and bearing pressure sleeve 15 are arranged in sequence from bottom to top, and two linear guide rails 16 are arranged in parallel on the lower end surface of the adapter plate 10; A pair of sliders 17 are arranged on the upper end surface, and the linear guide rail 16 is installed on the sliders 17 .

The working principle of the horizontal-axis floating connection mechanism of the utility model: when the Y-axis 2 and the Z-axis 4 move in the X direction along the X-axis 1 guide rail as a whole, due to various error reasons, if the two X-axis 1 are not absolutely parallel, the two The distance between the two X-axis 1 will be slightly larger or smaller, and then the slider 17 and the linear guide rail 16 installed on the movable end beam 6 of the X-axis 1 will have a slight position shift. Block 17 is in linear contact, and at this time, the linear guide rail 16 will be subjected to a longitudinal force; since the linear guide rail 16, the adapter plate 10 and the connecting shaft 8 are fixedly connected together, due to the effect of the longitudinal force, the three will go around together Rolling bearing Ⅰ11, rolling bearing Ⅱ12, rolling bearing Ⅲ13, rolling bearing Ⅳ14 rotate on the center line; since the movable end connecting bearing seat and the movable end beam connecting seat are fixed together and installed on the Y-axis beam, this part does not need to rotate; in this way, according to the linear guide rail The situation is different, and the direction of the longitudinal force is also different. The connecting shaft 8 will rotate slightly in different directions and at different angles, while the Y axis does not need to be adjusted, and is not disturbed by the two X axes that are not absolutely parallel. Purpose of shaft floating connection.
