Description

Laser measuring mechanism for length of screw rod

Technical Field

The utility model relates to the technical field of screw rod measurement, in particular to a laser measuring mechanism for the length of a screw rod.

Background

Most machine tools and automation equipment use roller screws as transmission or positioning components. The ball screw is an ideal product for converting rotary motion into linear motion or converting linear motion into rotary motion. Most of mechanical precision equipment uses a screw rod for positioning, transmission and the like. For precision equipment, the parts used also require greater precision. Accordingly, tolerance requirements are also relatively high when the screw rod is machined. The length tolerance of the wire rod is also a factor influencing the installation precision of the equipment and the running error of the equipment to be larger, and the length tolerance needs to be ensured within 0.2M. In traditional processing, because the demand of lead screw in the lathe is all longer, when reaching more than 1000MM, the measuring difficulty after the processing, if use slide caliper to measure, the length of measurement of slide caliper is limited, and the precision is lower when measuring longer size moreover, can only guarantee within 1M tolerance. Or after a longer screw rod is processed, the measuring tape is used for measuring, and the measuring precision cannot be achieved.

At present, most of processing measuring personnel generally use calipers or a meter ruler for measurement, but the use is troublesome, the measurement accuracy is not good, the measurement error limited by equipment is large, and the influence of human factors is large. The efficiency is low when the mass processing needs to be measured, the length tolerance of each wire rod cannot be ensured, and the use requirement of equipment with higher precision cannot be met.

Detailed Description

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may also be oriented 90 degrees or at other orientations and the spatially relative descriptors used herein interpreted accordingly.

The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. As shown in fig. 1, a laser measuring mechanism for the length of a screw rod comprises a marble platform 1, a linear slide rail 2, a right slide block 3, a first triangular support supporting slide block 4, a second triangular support supporting slide block 5, a first triangular support 6, a second triangular support 7, a front stop block 8, a rear stop block 9, a laser transmitter 10, a laser receiver 11 and a reading display screen 12; linear slide installs on the marble platform, first triangular support and second triangular support install respectively on the upper portion of first triangular support supporting slide and second triangular support supporting slide, first triangular support supporting slide and second triangular support supporting slide respectively with linear slide sliding fit, the backstop is fixed the upper portion of right side slider, right side slider are located linear slide's right side and rather than sliding fit, laser receiver fixes on the backstop, preceding backstop is fixed the left side of marble platform, laser transmitter install on the backstop and with laser receiver corresponds, the reading display screen is installed the upper portion of backstop.

In order to solve the problem of measuring the length after the screw rod is machined, the utility model provides the measuring platform which is suitable for the conditions and has the advantages of high measuring precision, high efficiency and convenience in operation. The measuring platform takes a marble table as a base and takes laser as a detection principle. During detection, the distance between the triangular iron supports is adjusted, the lead screw is aligned to the fixed baffle at the left end, and the sliding baffle at the right end is abutted to the tail end of the screw reversing rod. The receiver at the right end of the laser transmitter transmitting signal is connected with the laser micro-detection device for receiving the signal, and the display reads out the accurate distance length detection based on the laser micro-detection principle, so that the precision can reach 0.1MM, and the use conditions of most machine tools with higher precision are met.
