Description

Technical Field

[0001] The present application relates to the technical field of measuring instruments or components, and in particular to a probe target ball seat. Background Art

[0002] The laser tracking measurement system is a high-precision measuring instrument in the industrial measurement system. It integrates various advanced technologies such as laser interferometer ranging technology, photoelectric detection technology, precision machinery technology, computer and control technology, modern numerical calculation theory, etc., to track the moving target in space and measure the target's three-dimensional coordinates in real time. It has the characteristics of high precision, high efficiency, real-time tracking measurement, quick installation, and easy operation. It is suitable for large-size workpiece assembly measurement, measurement of stationary targets, tracking and measurement of moving targets or their combination.

[0003] At present, the application cases of laser trackers in the processing of FRP (fiber reinforced composite materials) products in the wind power industry are mainly reflected in the surface dimension detection of molds and products, the position dimension detection of product drilling holes, and the dimension detection of tooling. However, most of the laser tracker equipment on the market cannot directly detect the position dimension of the engraved lines on the FRP mold. They are generally used in conjunction with target balls to measure the straightness of the lines on the equipment. In order to facilitate the fixation of the target ball, a target seat is generally used to fix the target ball on the surface of the equipment to be tested. However, the existing target ball seat still has the following problems: 1. Based on the fact that the surface of FRP products in the wind power industry is sometimes non-planar, the existing target ball seat is not convenient to place stably during the measurement process, affecting the measurement accuracy; 2. The existing target ball seat used for equipment engraved line measurement is suitable for the protruding engraved lines on the equipment surface, and it is not convenient to measure the engraved lines recessed in the equipment surface, which is easy to cause measurement accuracy deviation; 3. At present, there is no target ball seat accessory that can measure both the product hole position and the product engraved lines, which makes it impossible to take into account the high-precision measurement of products in these two states.

[0004] Patent "A Laser Tracker Target" 2022204509237 discloses a target mount with a cross transparent ruler. Although it can conveniently adsorb and fix the target ball and measure the concave scale lines, the target mount can only detect concave scale lines on the plane. For products with many scale lines or holes on a non-plane, the target mount is difficult to measure and the measurement accuracy cannot be guaranteed.

[0005] In view of this, the probe target ball seat of the present application is proposed, which can be used for the measurement of scale lines on the surface of large equipment. It has low requirements for the flatness of the equipment surface and is suitable not only for flat facilities, but also for the precise measurement of scale lines on curved mold products. It also takes into account different styles of scale lines, such as the measurement of concave or convex scale lines or hole positions. Utility Model Content

[0006] To solve the above problems, the present utility model proposes a probe target ball seat, which is used in conjunction with a laser tracker and can more conveniently detect the position degree dimension of the mold engraving line, taking into account the measurement of the hole position and engraving line of the mold product, being more suitable for the precise measurement of the engraving line on flat and curved surface mold products, improving the detection accuracy and efficiency, reducing the detection cost, and solving the problems existing in the prior art.

[0007] The present utility model provides the following technical solutions:

[0009] Further, the target ball seat main body includes a cylinder body that is penetrated up and down, the magnetic support feet are arranged at the bottom end of the cylinder body, and the magnetic support feet are composed of a plurality of first strong magnetic columns.

[0010] Further, the first strong magnetic columns are evenly arranged at the bottom end of the cylinder body.

[0011] Further, second strong magnetic columns are arranged at the top inside the cylinder body, a strong magnetic sleeve seat is arranged outside the second strong magnetic columns, a spring is arranged below the strong magnetic sleeve seat, the probe is arranged below the spring, the bottom end of the probe extends out of the bottom end of the cylinder body under the action of the spring, and 4 magnetic support feet are arranged on the bottom surface of the cylinder body outside the probe.

[0013] Further, the strong magnetic sleeve seat is screwed to the inner wall of the cylinder body.

[0014] Further, the top inside the cylinder body is arranged as an inner concave arc surface that gradually expands outward from bottom to top, and the inner concave arc surface is adapted to the bottom of the target ball. This position is used to place the target ball and make the bottom of the target ball adsorbed and connected to the second strong magnetic column in the strong magnetic sleeve seat.

[0015] Further, the probe includes a conical bottom, a columnar middle part and a cylindrical top; the conical bottom extends out of the bottom end of the target ball seat main body; a boss is arranged at the lower part of the inner wall of the cylinder body, and the bottom end surface of the cylindrical top of the probe abuts against the boss under the action of the spring.

[0016] Through the probe target ball seat proposed by this application, the following beneficial effects can be brought:

It can not only measure flat products, but also be more convenient for measuring various styles of engraved lines on curved surface die products. Compared with the existing target ball seat, the types of measurement objects are expanded. While ensuring stable adsorption of the target ball, it can also be stably adsorbed on the surface of the product to be measured during the measurement process, with a wider scope of application and stronger applicability.

Detailed Embodiment

[0023] In order to more clearly explain the overall concept of the present application, the following will be described in detail by way of examples in conjunction with the drawings of the specification.

[0024] As Figures 1-3 shown, an embodiment of the present utility model discloses a probe target ball seat, which includes a target ball seat main body. The target ball seat main body is a cylinder body 1 that is penetrated up and down. A probe 2 is movably arranged in the cylinder body. The bottom of the probe extends out of the bottom end of the cylinder body. A plurality of first strong magnetic columns 3 are evenly spaced at the bottom end of the cylinder body. The first strong magnetic columns form magnetic support feet that firmly adsorb the target ball seat main body to the surface of the product to be measured.

[0025] The number of the above-mentioned strong magnetic columns is 4.

[0026] The inner top of the cylinder body 1 is provided with a concave arc surface that gradually expands outward from bottom to top, and the concave arc surface is adapted to the bottom of the target ball. A strong magnetic sleeve base 4 is detachably arranged on the inner wall of the cylinder body below the concave arc surface, and a second strong magnetic column 5 is fixedly arranged in the strong magnetic sleeve base; a spring 6 is arranged in the cylinder body below the strong magnetic sleeve base, and the probe 2 is arranged below the spring. The top end of the spring is fixedly connected to the bottom end of the strong magnetic sleeve base 4, and the bottom end of the spring is fixedly connected to the top end of the probe 2. The bottom end of the probe extends out of the bottom end of the cylinder body 1 under the action of the spring force.

[0027] The above-mentioned strong magnetic sleeve base 4 is screwed to the inner wall of the cylinder body 1.

[0028] The above-mentioned probe 2 includes a conical bottom 21, a columnar middle part 22 and a cylindrical top 23; a boss 11 is arranged at the lower part of the inner wall of the cylinder body. Under the action of the spring, the bottom end surface of the cylindrical top 23 of the probe abuts against the top surface of the boss 11.

[0029] Working principle:

[0030] When the above-mentioned probe target ball seat is in use, the target ball seat is placed above the position degree scale line of the product to be measured. Since the probe 2 is exposed below the target seat in the normal state (spring force), it can be used to contact the recessed or protruding scale line to confirm the position or position point of the scale line to be measured; then press down the target ball seat, and the probe 2 enters the cylinder body 1 due to the contraction of the spring 6. At this time, the first strong magnetic column 3 at the bottom end of the target seat body adsorbs the surface of the object to be measured, realizing the fixation of the target ball seat. Subsequently, the target ball is placed at the concave inner arc surface part at the top end of the cylinder body, and the bottom end of the target ball contacts and adsorbs the second strong magnetic column 5 in the strong magnetic sleeve base 4, realizing the adsorption and fixation of the target ball. Combined with a laser tracker, the measurement of the position to be measured is carried out.

[0031] Due to the setting of the magnetic support feet composed of the first strong magnetic columns 3, the target ball seat can be conveniently fixed on the surface of the non-planar product to be measured, especially facilitating the precise measurement of scale lines and hole positions on curved surface products.

[0032] When it is necessary to measure the position degree of the center of the cross intersection of the concave and convex scale lines or the position degree of the specified point of the scale line, the conical bottom 21 of the probe preferably realizes the positioning of the position of the target to be measured. Furthermore, due to the pressing down of the target seat and the contraction of the probe, the whole target seat is quickly fixed at this position, ensuring accurate measurement while improving the measurement efficiency and making the operation more flexible and convenient.
