Description

Technical Field

[0001] This utility model relates to the field of CNC mobile positioning equipment technology, and in particular to a CNC horizontal mobile positioning device. Background Technology

[0002] A CNC moving positioning device is a servo motion mechanism directly controlled by the NC system in a CNC system. It can be used for workpiece movement and positioning, such as linear axes (X / Y / Z) or rotary axes (A / B / C) in a machining center. In the automated machining of automotive body-in-white, the workpiece needs to be mounted on a traditional CNC moving positioning linear axis for movement and positioning. Workpiece movement may involve welding or cutting, resulting in weld slag and other impurities falling during the process. Furthermore, when loading or unloading workpieces or observing their condition, the operator needs to stand at a height for observation, requiring external tools (such as a ladder), increasing the complexity and time cost of the operation. In traditional moving positioning devices, the sliding block is located on the upper surface of the CNC moving positioning device, which has an upward clearance opening for the sliding block to slide. However, this clearance opening can only be protected against dust and impurities through a flexible structure, and its low structural strength cannot effectively prevent weld slag and other impurities, nor can it be used from a height. Therefore, it is necessary to improve existing CNC horizontal moving positioning devices to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a CNC horizontal moving positioning device. This solves the problem that traditional CNC moving positioning linear axes in the horizontal direction rely on flexible structures for dust and impurity prevention, but these structures have low strength, cannot effectively prevent welding slag and other impurities, and are not suitable for users to stand at a height.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A CNC horizontal moving positioning device includes a horizontal housing, a drive device, a linear motion mechanism, a rigid upper cover structure, and a flexible dustproof structure. The horizontal housing has a mounting cavity, and the drive device is installed at one end inside the mounting cavity. The linear motion mechanism includes a lead screw, a linear motion seat, and a slide rail. The lead screw is horizontally and rotatably disposed in the mounting cavity, the linear motion seat is screwed onto the lead screw, and the slide rail is horizontally mounted on the horizontal housing. The side of the linear motion seat is slidably engaged with the slide rail. The rigid upper cover structure covers the mounting cavity of the horizontal housing, and a clearance opening is provided between the lower end face of the rigid upper cover structure and the side of the mounting cavity. The side of the linear motion mechanism protrudes from the clearance opening to form a protruding end, the upper end face of the protruding end forms a mounting surface, and the flexible dustproof structure seals the clearance opening.

[0006] Furthermore, the rigid top cover structure includes a pair of suspension rods and a cover plate. The suspension rods are suspended above the two sides of the mounting cavity, and the two ends of the suspension rods are fixedly connected to the two ends of the horizontal housing. The cover plate is installed on the suspension rods. The suspension rods are spaced apart from the upper end of the side wall of the horizontal housing to form the clearance opening.

[0007] Furthermore, the rigid top cover structure also includes a plurality of connectors, which are arranged alternately between the suspension rods, and each end of the connector is connected to the suspension rod.

[0008] Furthermore, the cover plate is segmented, and the connection between adjacent cover plates is located above the connector.

[0009] Furthermore, the flexible dustproof structure includes a flexible belt, a left misaligned guide post group, and a right misaligned guide post group. The flexible belt is tightly sealed at the clearance opening of the mounting cavity. The left misaligned guide post group is located at the left end of the extended end of the linear motion seat, and the right misaligned guide post group is located at the right end of the extended end of the linear motion seat. The left misaligned guide post group includes two left rotating posts with parallel axes, which are misaligned. The right misaligned guide post group includes two right rotating posts with parallel axes, which are misaligned. The flexible belt passes through the left and right rotating posts and is attached to the outer wall of the extended end.

[0010] Furthermore, the horizontal housing is provided with clearance openings on both sides, and the linear motion seat is provided with protruding ends that pass through the two clearance openings; both clearance openings are provided with the flexible dustproof structure.

[0011] Furthermore, one end of the flexible strip is configured as a fixed end, which is fixedly connected to the flat shell; the other end of the flexible strip is configured as a movable end, which is connected by an elastic element to tighten the flexible strip.

[0012] Furthermore, each of the two flexible strips has a clamp at its movable end, and the flexible strip is connected to the elastic element through the clamp.

[0013] Furthermore, one end of the clamp is used to clamp the movable end of the flexible strip, and the two clamps are connected to each other through the elastic element.

[0014] Furthermore, the elastic element is a spring, and the end of the spring is hung on the clamp.

[0015] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model replaces the traditional design that relies solely on flexible structures for dust and impurity prevention by incorporating a rigid top cover structure. The rigid top cover structure not only effectively prevents welding slag and impurities from entering the device, but also significantly improves the overall structural strength of the device. Operators can safely perform elevated operations on the rigid top cover structure without the need for external tools, thus simplifying the process of loading and unloading workpieces and observing their condition, reducing operational complexity and time costs. This invention solves the problem of traditional horizontal CNC linear positioning axes relying on flexible structures for dust and impurity prevention, which have low structural strength, cannot effectively prevent welding slag and impurities, and are not suitable for users to stand on while operating at a height.

[0017] 2. This utility model, through the paired suspension rods, allows both sides of the linear motion seat to have protruding ends, forming paired mounting surfaces; the inclusion of connecting parts improves the structural strength of the rigid top cover. The segmented cover plate facilitates partial opening and closing, enhancing ease of use. Attached Figure Description
