Description

Technical Field

[0001] This utility model relates to cylinder measuring equipment, specifically to a comprehensive measuring device for the cylinder height and slot width of a refrigeration compressor. Background Technology

[0002] Cylinders, as power actuators, are widely used in various mechanical equipment, such as air conditioning compressors and hydraulic systems; the dimensional accuracy of cylinders directly affects their assembly quality. In the early days, manual measurement was mainly used for components with low measurement requirements. However, as industrial production has increased its requirements for measurement accuracy and efficiency, mechanical measuring devices have emerged. Mechanical measuring devices are used to measure cylinder height and slot width. Currently, cylinder height and slot width are usually measured separately, resulting in relatively low measurement efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a comprehensive measuring device for the cylinder height and slot width of a refrigeration compressor. The technical problem to be solved is how to improve measurement efficiency and realize automated measurement.

[0004] This utility model is achieved through the following technical solution:

[0005] A comprehensive measuring device for cylinder height and slot width of a refrigeration compressor includes a base, a pneumatic measuring instrument body, and a measuring head assembly, wherein the measuring head assembly and the pneumatic measuring instrument body are connected.

[0006] The aforementioned measuring head assembly includes a slot width measuring head and a height measuring head;

[0007] The aforementioned groove width measuring head is connected to the base via a sliding member, and the groove width measuring head slides via the sliding member;

[0008] The height measuring head is located at the end of the sliding component. When the slot width measuring head approaches the height measuring head, the cylinder on the slot width measuring head enters the measuring area of ​​the height measuring head, and the height measuring head measures the height of the cylinder.

[0009] This invention integrates a slot width measuring head and a height measuring head into a single device. When the slot width measuring head approaches the height measuring head, the cylinder can simultaneously be positioned for both measurements, allowing for a one-time measurement of both cylinder height and slot width. This reduces operational steps and improves measurement efficiency. When measuring cylinder height and slot width separately, each measurement requires repositioning the cylinder to ensure accuracy. Repeated repositioning is time-consuming and can lead to measurement errors due to inaccurate positioning. This invention, however, only requires the cylinder to be positioned once on the slot width measuring head. As the slot width measuring head slides closer to the height measuring head, the cylinder naturally enters the height measuring head's measurement area, eliminating the need for repositioning and avoiding the time and error issues associated with repeated repositioning, further improving measurement efficiency. Automated measurement is achieved through the coordinated operation of the pneumatic measuring instrument body and the measuring head assembly.

[0010] Furthermore, the aforementioned sliding component includes a slide rail and a slider, the slide rail being disposed on the base and the slide rail and slider being adapted to each other; the aforementioned groove width measuring head is disposed on the slider.

[0011] Furthermore, the aforementioned slider also includes a driver, the output end of which is connected to the slot width measuring head or the slider; the driver drives the slot width measuring head to slide.

[0012] The slider slides along the slide rail, which can quickly move the slot width measuring head to the position corresponding to the height measuring head, avoiding repeated adjustments caused by uneven or inaccurate sliding. Using the driver to push the slot width measuring head reduces operation time and improves measurement efficiency compared to manually pushing the slot width measuring head for positioning.

[0013] Furthermore, a first hydraulic buffer is provided between the aforementioned slot width measuring head and height measuring head, with the two ends of the first hydraulic buffer used to contact the slot width measuring head and the height measuring head, respectively.

[0014] The functions of the first hydraulic buffer are as follows: First, to prevent rigid collisions between the slot width measuring head and the height measuring head, which would cause vibrations during measurement and affect the measurement accuracy; Second, to prevent rigid collisions between the cylinder and the height measuring head, which would cause vibrations and affect the measurement accuracy.

[0015] Furthermore, the height measuring head includes an upper plate, a middle plate and a lower plate arranged in sequence. The middle plate extends from the side of the upper plate and the lower plate near the slot width measuring head, and the gap between the upper plate and the lower plate forms a measuring cavity.

[0016] Both the upper and lower plates of the aforementioned intermediate plate are provided with a first air hole, which is connected to the body of the pneumatic measuring instrument.

[0017] The measuring cavity formed between the upper and lower plates provides a fixed space for measuring the cylinder height. When the slot width measuring head moves the cylinder close to the height measuring head, the cylinder can quickly enter the measuring cavity. After entering the measuring cavity, the cylinder's height position is relatively fixed. The pneumatic gauge body can acquire the pneumatic signal related to the cylinder height in one go through the first air hole, avoiding the need for multiple measurements due to unstable cylinder position, reducing the number of measurements and time, and further improving measurement efficiency. Both the upper and lower plates are provided with a first air hole communicating with the pneumatic gauge body, allowing the pneumatic gauge body to acquire pneumatic signals from multiple positions above and below the cylinder simultaneously; compared to single air hole acquisition, cylinder height information can be collected more quickly.

[0018] Furthermore, the aforementioned groove width measuring head includes a guide platform and a protrusion, the protrusion being disposed on the guide platform and used to be fitted inside the cylinder groove;

[0019] The aforementioned guide platform and protrusion are provided with a second air hole, which is connected to the body of the pneumatic measuring instrument.

[0020] The protrusion is fitted inside the cylinder groove, allowing the operator to quickly position the cylinder to the groove width measuring head's measurement position during measurement; the guide table provides support for the protrusion. Both the guide table and the protrusion are equipped with a second air hole that communicates with the pneumatic gauge body, enabling the pneumatic gauge body to simultaneously acquire pneumatic signals from different positions in the cylinder groove.

[0021] Furthermore, when measuring the height of the cylinder, the slot width measuring head slides towards the height measuring head, and the cylinder on the slot width measuring head enters the measuring chamber of the height measuring head, with the cylinder corresponding to the first air hole.

[0022] Furthermore, a second hydraulic buffer is provided at the end of the groove width measuring head that is away from the height measuring head.

[0023] The aforementioned second hydraulic damper prevents the groove width measuring head from sliding off the slide rail during sliding, and is used for limiting its position.

[0024] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0025] This invention integrates a slot width measuring head and a height measuring head into a single device. When the slot width measuring head approaches the height measuring head, the cylinder can simultaneously be positioned for both measurements, allowing for a one-time measurement of both cylinder height and slot width. This reduces the number of steps involved in the measurement process, thereby improving efficiency. When measuring cylinder height and slot width separately, each measurement requires repositioning the cylinder to ensure accuracy. Repeated repositioning is not only time-consuming but can also lead to measurement errors due to inaccurate positioning. This invention, however, only requires the cylinder to be positioned once on the slot width measuring head. As the slot width measuring head slides closer to the height measuring head, the cylinder naturally enters the measurement area of ​​the height measuring head, eliminating the need for repeated positioning and avoiding the time and error issues associated with repetitive positioning, further improving measurement efficiency.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0032] First embodiment:

[0033] Combination Figure 1A comprehensive measuring device for cylinder height and slot width of a refrigeration compressor includes a base 1, a pneumatic gauge body and a measuring head assembly, wherein the measuring head assembly and the pneumatic gauge body (which may be a float-type pneumatic gauge, an electronic pneumatic gauge and a pointer-type pneumatic gauge) are connected.

[0034] The aforementioned measuring head assembly includes a slot width measuring head and a height measuring head;

[0035] The aforementioned groove width measuring head is connected to the base 1 via a sliding member, and the groove width measuring head slides via the sliding member;

[0036] The height measuring head is located at the end of the sliding member. When the groove width measuring head approaches the height measuring head, the cylinder 7 on the groove width measuring head enters the measuring area of ​​the height measuring head, and the height of the cylinder 7 is measured by the height measuring head.

[0037] In the existing technology, the measuring devices for cylinder height and slot width are usually measured separately, requiring the use of different measuring devices and two independent measurement operations, which is cumbersome and time-consuming.

[0038] To simplify operation, the slot width measuring head and height measuring head are integrated into a single device. When the slot width measuring head approaches the height measuring head, the cylinder 7 can simultaneously be positioned for both measurements, allowing for a one-time measurement of both the cylinder 7's height and slot width. This reduces the number of steps required during measurement and improves efficiency. When measuring the cylinder 7's height and slot width separately, each measurement requires repositioning the cylinder 7 to ensure accuracy. Repeated repositioning is time-consuming and can lead to measurement errors due to inaccurate positioning. In this invention, the cylinder 7 only needs to be positioned on the slot width measuring head once. As the slot width measuring head slides closer to the height measuring head, the cylinder 7 naturally enters the height measuring head's measurement area, eliminating the need for repositioning and avoiding the time and error issues associated with repeated repositioning, further improving measurement efficiency.

[0039] Second embodiment:

[0040] Based on the first embodiment, the sliding member includes a slide rail 41 and a slider 42. The slide rail 41 is disposed on the base 1, and the slide rail 41 and the slider 42 are adapted to each other. The groove width measuring head is disposed on the slider 42.

[0041] In a specific embodiment, the sliding member further includes a driver 6 (which may be a CDM2L25 cylinder 7), the output end of which is connected to the slot width measuring head or the slider 42; the driver 6 drives the slot width measuring head to slide.

[0042] The slider 42 slides along the slide rail 41, which can quickly move the slot width measuring head to the position corresponding to the height measuring head, avoiding repeated adjustments caused by uneven or inaccurate sliding. The drive 6 pushes the slot width measuring head, which reduces operation time and improves measurement efficiency compared to manually pushing the slot width measuring head for positioning.

[0043] Third embodiment:

[0044] Based on any of the above embodiments, a first hydraulic buffer 51 (which may be RB1007) is provided between the groove width measuring head and the height measuring head. The two ends of the first hydraulic buffer 51 are used to contact the groove width measuring head and the height measuring head, respectively.

[0045] The functions of the first hydraulic buffer 51 are as follows: First, to prevent rigid collision between the groove width measuring head and the height measuring head, which would cause vibration during measurement and affect the measurement accuracy; Second, to prevent rigid collision between the cylinder 7 and the height measuring head, which would cause vibration and affect the measurement accuracy.

[0046] Fourth embodiment:

[0047] Based on any of the above embodiments, the height measuring head includes an upper plate 31, a middle plate 32 and a lower plate 33 arranged in sequence. The middle plate 32 extends from the side of the upper plate 31 and the lower plate 33 near the slot width measuring head. The gap between the upper plate 31 and the lower plate 33 forms a measuring cavity 34.

[0048] The upper plate 31 and the lower plate 33 of the aforementioned intermediate plate 32 are both provided with a first air hole, which is connected to the body of the pneumatic measuring instrument.

[0049] In a specific embodiment, when measuring the height of the cylinder 7, the slot width measuring head slides towards the height measuring head, and the cylinder 7 on the slot width measuring head enters the measuring chamber 34 of the height measuring head, with the cylinder 7 corresponding to the first air hole.

[0050] The measuring cavity 34 formed between the upper plate 31 and the lower plate 33 provides a fixed space for measuring the height of the cylinder 7. When the slot width measuring head moves the cylinder 7 close to the height measuring head, the cylinder 7 can quickly enter the measuring cavity 34. After entering the measuring cavity 34, the height position of the cylinder 7 is relatively fixed. The pneumatic gauge body can acquire the pneumatic signal related to the height of the cylinder 7 at once through the first air hole, avoiding the need for multiple measurements due to the unstable position of the cylinder 7, reducing the number of measurements and time, and further improving the measurement efficiency. Both the upper plate 31 and the lower plate 33 are provided with a first air hole that communicates with the pneumatic gauge body, so that the pneumatic gauge body can acquire pneumatic signals from multiple positions above and below the cylinder 7 at the same time; compared with single air hole acquisition, the height information of the cylinder 7 can be collected more quickly.

[0051] Fifth embodiment:

[0052] Based on any of the above embodiments, combined with Figure 2 The groove width measuring head includes a guide plate 21 and a protrusion 22. The protrusion 22 is disposed on the guide plate 21 and is used to fit into the groove of the cylinder 7.

[0053] The guide platform 21 and the protrusion 22 are provided with a second air hole, which is connected to the body of the pneumatic measuring instrument.

[0054] The protrusion 22 is fitted inside the slot of the cylinder 7, allowing the operator to quickly position the cylinder 7 to the slot width measuring head during measurement. The guide table 21 provides support for the protrusion 22. Both the guide table 21 and the protrusion 22 are provided with a second air hole that communicates with the pneumatic gauge body, allowing the pneumatic gauge body to simultaneously acquire pneumatic signals from different positions in the slot of the cylinder 7.

[0055] Sixth embodiment:

[0056] Based on any of the above embodiments, a second hydraulic buffer 52 (which may be RB1007) is provided at the end of the groove width measuring head that is away from the height measuring head.

[0057] The aforementioned second hydraulic buffer 52 prevents the groove width measuring head from sliding out of the slide rail 41 during sliding, and is used for limiting the position.
