[0021] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-6 , the present invention provides a technical solution: a comprehensive measuring device for manufacturing hydraulic parts of engineering machinery, including a comprehensive measuring instrument for hydraulic parts of engineering machinery, the comprehensive measuring instrument for hydraulic parts of engineering machinery including a base 1, an X-axis 11, a Y-axis 12, a Z-axis 13, a parts placement block 2, an infrared detector 3, a parallelism detector 4 and an intelligent measuring system;

[0023] The X-axis 11 and the Y-axis 12 both include a slide bar 5 and a slider 6, the Z-axis 13 includes a lifting rod 7 and a lifting chamber 8, the lifting chamber 8 is fixedly installed above the base 1, the lifting rod 7 is connected to the inside of the lifting chamber 8, the slide bar 5 of the Y-axis 12 is fixedly connected to the lifting rod 7, the slider 6 of the Y-axis 12 is slidably connected to the slide bar 5 of the Y-axis 12, the slide bar 5 of the X-axis 11 is fixedly connected to the slider 6 of the Y-axis 12, the slider 6 of the X-axis 11 is slidably connected to the slide bar 5 of the X-axis 11, and the parallelism detector 4 is fixedly connected to the slider 6 of the X-axis 11;

[0024] The parts placement block 2 is fixedly installed above the base 1 and below the parallelism detector 4. The infrared detector 3 is located on the left side of the parts placement block 2 and is fixedly connected to the top of the base 1. A thickness detection module is arranged inside the infrared detector 3. The thickness detection module is used to irradiate infrared rays onto the hydraulic components through the infrared detector 3 and identify the thickness size of the hydraulic components.

[0025] The operator places the hydraulic component into the part placement block 2, and then the lifting chamber 8 operates to make the lifting rod 7 descend, thereby driving the X-axis 11 to descend through the Y-axis 12, and the X-axis 11 drives the parallelism detector 4 to descend until it contacts the hydraulic component. Then the operator slides the slider 6 on the Y-axis 12, thereby driving the parallelism detector 4 to move along the Y-axis 12 direction through the X-axis 11, and measures the parallelism of the Y-axis 12 of the hydraulic component. Then the parallelism detector 4 is moved to the upper right side of the hydraulic component, and then the slider 6 on the X-axis 11 is slid to move the parallelism detector 4 along the X-axis 11 direction, and the parallelism of the X-axis 11 of the hydraulic component is measured. At the same time, the infrared detector 3 emits infrared rays to irradiate the hydraulic component, and the thickness size of the hydraulic component is detected by the thickness detection module, so as to achieve the effect of comprehensive measurement, and the measurement process is convenient and efficient, which can speed up the measurement efficiency.

[0026] The lifting chamber 8 includes a sleeve 81, a connecting rod 82, a motor 83, and a gear 84;

[0027] A sliding plug 821 is fixedly installed at the bottom end of the connecting rod 82, and the sliding plug 821 is slidably connected to the inner wall of the sleeve 81, and the sleeve 81 is fixedly installed at the bottom of the inner wall of the lifting chamber 8. A plurality of tooth blocks 822 are arranged on the left side of the connecting rod 82, and mesh with the gear 84. The motor 83 is fixedly installed on the front side of the inner wall of the lifting chamber 8, and the gear 84 is fixedly connected to the output end of the motor 83.

[0028] The upper end of the connecting rod 82 is fixed to the lower end of the lifting rod 7. A through hole is provided above the lifting chamber 8, and the inner diameter of the through hole is larger than the outer diameter of the lifting rod 7 and the connecting rod 82.

[0029] Through the above steps, during the measurement process, the motor 83 runs, driving the gear 84 to rotate, and the gear 84 drives the connecting rod 82 to move downward by meshing with the tooth block 822. The connecting rod 82 drives the sliding plug 821 to slide downward along the inner wall of the sleeve 81. The connecting rod 82 moves the parallelism detector 4 downward through the lifting rod 7 until it contacts the upper surface of the hydraulic component, thereby facilitating subsequent measurement work. The sliding of the sliding plug 821 and the inner wall of the sleeve 81 makes the lifting process smooth and avoids shaking, thereby improving the measurement accuracy, and automatically lowering the parallelism detector 4, which can relatively save time and improve the measurement efficiency. After the measurement is completed, the motor 83 rises and resets, and efficient continuous measurement work can be carried out, and the work efficiency is greatly improved.

[0030] A hydraulic chamber 85 is fixedly installed on the right side of the inner wall of the lifting chamber 8, a hydraulic plate 851 is slidably connected to the inner wall of the hydraulic chamber 85, the hydraulic plate 851 is spring-connected to the right side of the inner wall of the hydraulic chamber 85, a hydraulic rod 852 is fixedly connected to the left side of the hydraulic plate 851, and a push-pull block 853 is fixedly connected to the front side of the hydraulic rod 852;

[0031] An arc block 841 is fixedly installed on one side of the gear 84, and both ends of the arc block 841 are in an arc shape. The bottom end of the push-pull block 853 is in an arc shape, and the extended length exceeds the position of the arc block 841. The right side of the hydraulic plate 851 is filled with hydraulic oil. A telescopic joint 811 is fixedly installed on the bottom of the inner wall of the sleeve 81, and an elastic spring is arranged inside the telescopic joint 811. The telescopic joint 811 is connected to the right pipeline of the hydraulic chamber 85, and a one-way valve is arranged in the pipeline. The hydraulic chamber 85 is connected to the external hydraulic oil pipeline;

[0032] During the rotation of gear 84, arc block 841 is driven to rotate around its center until arc block 841 contacts and squeezes push-pull block 853. Push-pull block 853 is forced to drive hydraulic plate 851 to slide to the right along the inner wall of hydraulic chamber 85 through hydraulic rod 852. The spring is deformed by force. At the same time, hydraulic oil is squeezed into telescopic joint 811 through the pipeline to stretch it. Since telescopic joint 811 is elastic, when it is filled with hydraulic oil, after sliding plug 821 moves downward and contacts telescopic joint 811, telescopic joint 811 generates buffer force, thereby avoiding excessive squeezing of parallelism detector 4 and hydraulic components to damage components and parallelism detector 4, thereby protecting products and instruments.

[0033] Afterwards, the arc block 841 is out of contact with the push-pull block 853, and the spring generates a reaction force to reset the hydraulic plate 851. At this time, the greater the distance between the parallelism detector 4 and the components, the more turns the gear 84 makes, the more reciprocating motions the hydraulic plate 851 makes, the greater the hydraulic pressure in the telescopic joint 811, and the greater the buffering strength, thereby further improving the protection effect of the parallelism detector 4 and the components, and fully avoiding damage to both.

[0034] The expansion joint 811 is connected to the right side of the hydraulic chamber 85 with a return pipe 86, and a pressure valve is provided inside the return pipe 86;

[0035] The upper end of the expansion joint 811 is tapered, and a tapered groove 823 is provided at the bottom of the sliding plug 821. The inner diameter of the tapered groove 823 is smaller than the outer diameter of the cone at the upper end of the expansion joint 811, and a chamfer is provided at the notch of the tapered groove 823.

[0036] When the sliding plug 821 and the expansion joint 811 contact and squeeze each other, the internal oil of the expansion joint 811 is further squeezed, and the pressure is further increased, thereby reaching the pressure bearing limit of the pressure valve, causing it to open, and the hydraulic oil flows back to the hydraulic chamber 85 through the return pipe 86, so as to facilitate the next buffering work. When the sliding plug 821 and the expansion joint 811 squeeze each other, the cone at the upper end of the expansion joint 811 is pressed into the conical groove 823, and then when the sliding plug 821 is reset, the expansion joint 811 is stretched, so that the internal elastic spring is stretched, preventing the elastic spring from being continuously pressed downward and causing a reduction in service life, and the elasticity of the elastic spring can be relatively guaranteed.

[0037] The intelligent measurement system includes a height detection module and a central control module;

[0038] The height detection module is arranged inside the infrared detector 3 and is electrically connected to the central control module. The central control module is electrically connected to the motor 83. The height detection module is used to determine the distance between the parallelism detector 4 and the hydraulic components through infrared irradiation of the infrared detector 3. The central control module is used to control the number of rotations of the motor 83 according to the distance between the parallelism detector 4 and the hydraulic components.

[0039] The operation steps of the intelligent measurement system include:

[0040] Step S1, the intelligent measurement system is running, the infrared detector 3 measures the thickness of the hydraulic component, and at the same time, the infrared detector 3 irradiates the infrared light to determine the distance between the parallelism detector 4 and the hydraulic component;

[0041] Step S2, controlling the number of revolutions of the motor 83 according to the distance between the parallelism detector 4 and the hydraulic component, thereby controlling the parallelism detector 4 to descend and automatically adjusting the descending distance;

[0042] Step S3, after the detection end of the parallelism detector 4 contacts the component, the infrared detector 3 recognizes that the two are in contact and controls the motor 83 to stop running;

[0043] Step S4, the operator slides the slider 6 of the Y-axis 12 at the same time to measure the parallelism of the Y-axis 12 of the hydraulic component, and then slides the slider 6 of the X-axis 11 to measure the parallelism of the X-axis 11 of the hydraulic component.

[0044] In step S1 and step S2, the number of rotations of the motor 83 is adjusted by the intelligent measurement system, so that the parallelism detector 4 automatically descends to contact the upper surface of the hydraulic component, thereby performing parallelism measurement;

[0045] The number of revolutions of the motor 83 is calculated as follows: , is the number of revolutions of the motor 83, is the maximum number of rotations of the motor 83, is the distance between the parallelism detector 4 and the hydraulic components, It is the maximum distance between the parallelism tester 4 and the hydraulic components. The larger the maximum distance between the parallelism tester 4 and the hydraulic components, the more revolutions the motor 83 makes, so that the parallelism tester 4 can be lowered further. On the one hand, it can ensure that the parallelism tester 4 can smoothly contact the hydraulic components, thereby facilitating rapid measurement of the parallelism dimensions of the hydraulic components. On the other hand, it can prevent the parallelism tester 4 from being lowered too much, causing excessive squeezing and damaging the hydraulic components, and prevent the parallelism tester 4 from being damaged. It also enables intelligent measurement, high efficiency and convenience.
