Description

Technical Field

[0001] The utility model relates to the technical field of three-coordinate measuring machines, in particular to a fixed structure for detecting three-coordinate measuring machines. Background Art

[0002] The three-dimensional coordinate measuring machine is a commonly used precision measuring equipment used to measure and inspect geometric features such as size, shape and position of objects. It obtains the coordinate data of points by measuring the position of the object on three coordinate axes, and analyzes and compares these data. The three-dimensional coordinate measuring machine consists of a measuring platform, a probe system, a computer control system and measurement software. Its working principle is based on technologies such as laser, photoelectric, capacitance or mechanical triggering, and can achieve non-contact or trigger measurement of the surface of an object. When using a three-dimensional coordinate measuring machine for measurement, first place the object to be measured on the measuring platform and set the starting position of the probe system. Then, through the control system and measurement software, the probe system will move to the specified measuring point along the three coordinate axes of X, Y, and Z, and record the coordinate data of the point. Through the combination of multiple measuring points, the geometric features and dimensional data of the object can be obtained, and compared and analyzed with the design requirements or standards. When using a three-dimensional coordinate measuring machine, a fixing mechanism is generally required for use.

[0003] However, the existing fixing mechanism has a visual blind spot when fixing, which reduces the detection accuracy and makes it impossible to fix objects to be detected of different specifications well. Therefore, it does not meet the detection requirements. In this regard, we propose a fixing structure for three-coordinate measuring machine detection. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2The utility model provides an embodiment: a fixed structure for three-dimensional coordinate measuring machine detection, including a detection platform 1, a vertical plate 3 is fixedly connected to the left side of the top wall of the detection platform 1, and the front and rear ends of the right side of the vertical plate 3 are rotatably connected to the electric telescopic rods 4, and the output ends of the two electric telescopic rods 4 are rotatably connected to the fixed plates 5, and the two adjacent fixed plates 5 are rotatably connected by a turning page 7, and the left side of the turning page 7 is fixedly connected to the middle part of the right side of the vertical plate 3, and the top walls of the two fixed plates 5 are threaded with threaded knobs 6, and the bottom ends of the two threaded knobs 6 are threadedly connected to the clamps 8, and the middle part of the top wall of the detection platform 1 is fixedly connected to the measuring machine equipment 11; the middle parts of the two threaded knobs 6 are fixedly connected to the rubber rings 10; the right sides of the two clamps 8 are fixedly installed with rubber pads 9;

[0030] Specifically, according to the shape, size and weight of the object to be detected, we can select the most suitable clamp 8. These clamps 8 may include various types such as suction cups, claws, and pressure plates to meet the needs of different objects. After selecting the clamp 8, the next step is to fix the clamp 8 on the right side of the two corresponding fixed plates 5 through the threaded knob 6. By starting the two electric telescopic rods 4, the two fixed plates 5 can be displaced, so as to adjust the spacing between the clamps 8 to adapt to the objects to be detected of different sizes. The turning page 7 is fixed to the right side of the vertical plate 3 and makes the two fixed plates 5 rotate and connect. In this way, when the electric telescopic rod 4 drives the fixed plate 5 to displace, the turning page 7 can limit the displacement of the fixed plate 5 to complete the rotation, so that the two clamps 8 can fix the objects to be detected more firmly. In addition, it can adapt to various types of objects to be detected, so as to ensure that each object can be accurately detected. The top wall of the fixed plate 5 can be protected by two rubber rings 10, which reduces the rotation damage of the threaded knob 6, and the fixing effect of the clamp 8 is improved by two rubber pads 9.

[0031] Reference Figure 1 and Figure 3 The bottom wall of the testing platform 1 is provided with an extraction mechanism 2, which includes an extraction fan 201. The top wall of the extraction fan 201 is fixedly installed on the front side of the bottom wall of the testing platform 1. The output end of the extraction fan 201 is connected with a connecting pipe 202. The rear ends of the two connecting pipes 202 are connected with a collecting box 203. The inner wall of the collecting box 203 is fixedly installed with a filter plate 204. The left side of the collecting box 203 is rotatably connected with a movable door 205. The rear side of the collecting box 203 is connected with an extraction pipe 206. The top of the extraction pipe 206 is connected with an extraction head 208. A rubber ring 207 is fixedly installed on the top of the outer wall of the extraction pipe 206. The outer wall of the rubber ring 207 is fixedly connected to the rear side of the extraction head 208.

[0032] Specifically, when the extraction fan 201 is started, the extraction head 208 and the extraction pipe 206 can extract the dust and impurities that fall on the top of the test platform 1, and then collect them uniformly into the collection box 203, thereby greatly reducing the dust and impurities that fall on the items to be tested. These dusts often contain particles of various sizes, among which larger particles may damage key components such as the impeller if they directly enter the interior of the extraction fan 201. In order to solve this problem, a filter plate 204 is specially provided in the system. The main function of the filter plate 204 is to preliminarily filter the dust and impurities that enter the collection box 203, and isolate the larger particles outside the filter plate 204. In this way, only smaller particles can pass through the filter plate 204 and enter the collection box 203, thereby avoiding the potential damage of the larger particles to the impeller inside the extraction fan 201. This design not only extends the service life of the extraction fan 201, but also ensures the cleanliness and normal operation of the entire measuring machine, and reduces the wear of the extraction pipe 206 through two rubber rings 207.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The front side of the measuring machine 11 is fixedly connected with a control switch 12, and the control switch 12 is electrically connected to the extraction fan 201, the measuring machine 11 and the electric telescopic rod 4 respectively; the front side of the control switch 12 is provided with a protective shell 13, and the rear side of the protective shell 13 is rotatably connected to the front side of the measuring machine 11 through a hinge; the left and right sides of the bottom wall of the testing platform 1 are fixedly connected with a base frame 14, and the front and rear sides of the bottom of the two base frames 14 are fixedly installed with corner pads 15;

[0034] Specifically, through the control switch 12 electrically connected to the extraction fan 201, the measuring machine device 11 and the electric telescopic rod 4 respectively, the control switch 12 can complete the opening and closing of the device, and the protective shell 13 can protect the control switch 12 and prevent accidental touch.

[0035] Working principle: Before starting the inspection, select a suitable clamp 8 according to the object to be inspected, and fix the selected clamp 8 on the right side of the two corresponding fixed plates 5 through the threaded knob 6. By starting the two electric telescopic rods 4, the two fixed plates 5 can be displaced. When the turning page 7 is fixed to the right side of the vertical plate 3 and the rotation connection is made, the two fixed plates 5 can be rotated and clamped, so as to complete the fixation of the object to be inspected, so that the fixing mechanism can replace the clamp 8 according to the objects of different specifications, thereby improving the fixing effect and the detection accuracy, avoiding the situation where there are errors in the detection results, and by starting the extraction fan 201, the extraction head 208 and the extraction tube 206 can extract dust and impurities, and then collect them into the collection box 203, thereby reducing the dust and impurities dropped by the object to be inspected. The filter plate 204 allows the isolation of larger particles, thereby avoiding damage to the impeller inside the extraction fan 201, and ensuring the cleanliness and normal operation of the measuring machine.
