Description

Technical Field

[0001] The utility model relates to the field of orifice plates, in particular to a processing and positioning device for crescent-shaped orifice plates. Background Art

[0002] The orifice plate is a differential pressure flow meter. Its working principle is the same as other differential pressure flow meters, which is based on the principle of energy conversion in a sealed pipe: in the case of an ideal fluid, the flow rate in the pipe is proportional to the square root of the differential pressure; the flow rate in the pipe can be calculated based on the Bernoulli equation using the measured differential pressure value. The balanced flow sensor is a porous disc throttling rectifier installed on the cross section of the pipe. The size and distribution of each hole are customized based on special formulas and test data, called functional holes. When the fluid passes through the functional holes of the disc, the fluid will be balanced and rectified, the eddy current will be minimized, and an approximately ideal fluid will be formed. Through the pressure taking device, a stable differential pressure signal can be obtained, and the volume flow rate and mass flow rate can be calculated according to the Bernoulli equation.

[0003] During the production and processing of the orifice plate, it needs to be positioned. However, the positioning device in the existing technical solution cannot position orifice plates of different sizes due to its relatively simple structure, which leads to limitations in the use of the positioning device. Utility Model Content

[0004] The embodiment of the present application provides a processing positioning device for a crescent-shaped orifice plate, thereby solving the technical problem that the positioning device in the prior art solution cannot position orifice plates of different sizes due to its relatively simple structure, which results in the positioning device being subject to limitations when in use.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A processing and positioning device for a crescent-shaped orifice plate comprises a base, a support block for supporting the orifice plate, a supporting device for positioning the orifice plate, a sliding device for driving the supporting device to move, and a support frame for supporting the sliding device; the support block is arranged at the top center of the support frame; the support frame is arranged on the base; the support frame is provided with a plurality of groups of slide grooves arranged in a circular array of the support blocks; the sliding device is arranged at each group of the slide grooves; and the supporting device is arranged on each group of the sliding devices.

[0007] A further technical solution is: the sliding device includes a slider sliding on the sliding groove, a threaded rod for driving the slider to slide, and a bearing seat for supporting the threaded rod; the slider is threadedly connected to the threaded rod; the bearing seats are provided at both ends of the threaded rod; two groups of the bearing seats are provided at the bottom of the support frame, and the two groups of the bearing seats are symmetrically arranged in the sliding groove.

[0008] A further technical solution is: the abutment device includes an arc-shaped baffle for abutting against the orifice plate, a spring for buffering the arc-shaped baffle and a telescopic rod for limiting the spring; the spring is arranged around the telescopic rod; the telescopic end of the telescopic rod is connected to the arc-shaped baffle; the other end of the telescopic rod is connected to the slider.

[0009] A further technical solution is: the sliding device also includes a threaded handle; the threaded handle is arranged at one end of the threaded rod.

[0010] A further technical solution is: the abutting device further comprises a rubber pad; the rubber pad is arranged on the arc-shaped baffle.

[0011] A further technical solution is: the processing and positioning device for the crescent-shaped orifice plate also includes a damping block; a plurality of groups of the damping blocks arranged in a circular array are arranged on the top of the support block.

[0012] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0013] 1. Due to the use of the seat, support block, abutment device, sliding device and support frame, when the orifice plate needs to be positioned, the orifice plate must first be placed on the support block and the orifice plate and the support block are concentric. Then, the three sets of sliding devices are adjusted in sequence so that the sliding ends of the three sets of sliding devices respectively move toward the orifice plate with the corresponding abutment devices, and the three sets of abutment devices abut against the orifice plate at the same time, and the orifice plate can be fixed at this time. Since the spacing between the three sets of abutment devices can be adjusted by the corresponding sliding devices, the three sets of abutment devices can be used to fix orifice plates of different sizes, thereby improving the practicality of the processing positioning device to a certain extent.

[0014] 2. Due to the arrangement of the slider, threaded rod and bearing seat, since the slider is threadedly connected to the threaded rod and the slider slides on the slide groove, when the threaded rod is rotated, the slider can slide back and forth along the slide groove, thereby driving the abutment device to move closer to the support block or away from the support block.

[0015] 3. Due to the use of the setting of the arc baffle, spring and telescopic rod, when the slider slides along the slide groove, the supporting device moves close to the support block, and the arc baffle in the supporting device can be pressed against the orifice plate. When the three groups of arc baffles are pressed against the orifice plate at the same time, and the three groups of arc baffles are moved a certain distance toward the orifice plate again, the three groups of arc baffles will be subjected to a certain extrusion force at the same time, and compress the corresponding springs and telescopic rods. At this time, the springs in the compressed state will produce equal reaction forces on the arc baffles, so that the three groups of arc baffles can be firmly pressed against the orifice plate, and the orifice plate can be fixed at this time. Through the setting of the spring, when the arc baffle is pressed against the orifice plate, the spring has a certain buffering effect, and thus can play a certain protective role on the orifice plate. When the spring is in a compressed state, the telescopic rod can prevent the spring from deforming, and thus can play a certain protective role on the spring.

[0016] 4. Due to the setting of the threaded handle, the threaded rod can be driven to rotate by rotating the threaded handle, which makes it convenient for the staff to operate.

[0017] 5. Due to the setting of the rubber pad, when the arc baffle is against the orifice plate, the rubber pad on the arc baffle will contact the orifice plate, thereby preventing the arc baffle from causing unnecessary wear to the orifice plate, thereby providing a certain degree of protection for the orifice plate.

[0018] 6. Due to the setting of the damping block, when the orifice plate is placed on the support block, the damping block on the support block will contact the orifice plate, thereby increasing the friction between the support block and the orifice plate, thereby preventing the orifice plate placed on the support block from being displaced.

[0024] The embodiment of the present application provides a processing positioning device for a crescent-shaped orifice plate, thereby solving the technical problem that the positioning device in the prior art solution cannot position orifice plates of different sizes due to its relatively simple structure, which results in the positioning device being subject to limitations when in use.

[0025] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] A processing positioning device for a crescent-shaped orifice plate, such as Figure 1 As shown, it includes a base 1, a support block 2 for supporting the orifice plate, a supporting device 3 for positioning the orifice plate, a sliding device 4 for driving the supporting device 3 to move, and a support frame 5 for supporting the sliding device 4. The support block 2 is arranged at the top center of the support frame 5. The support frame 5 is arranged on the base 1. The support frame 5 is provided with a plurality of groups of slide grooves 51 arranged in a circumferential array of the support block 2. A sliding device 4 is arranged at each group of slide grooves 51. A supporting device 3 is arranged on each group of sliding devices 4.

[0028] The support block 2 is fixedly connected to the center of the top of the support frame 5. The support block 2 is preferably a cylinder. The support frame 5 is fixedly connected to the top of the base 1. The support frame 5 is provided with three groups of slide grooves 51 arranged in a circumferential array around the support block 2. The bottom of the support frame 5 is fixedly connected to each group of slide grooves 51. The sliding end of each group of slide devices 4 is fixedly connected to the abutment device 3. The sliding end of each group of slide devices 4 slides in the corresponding slide groove 51.

[0029] Due to the arrangement of the seat 1, the support block 2, the abutment device 3, the sliding device 4 and the support frame 5, when the orifice plate needs to be positioned, the orifice plate needs to be placed on the support block 2 first, and the orifice plate and the support block 2 are concentric, and then the three sets of sliding devices 4 are adjusted in sequence, so that the sliding ends of the three sets of sliding devices 4 respectively carry the corresponding abutment devices 3 to move toward the orifice plate, and the three sets of abutment devices 3 are abutted against the orifice plate at the same time, and the orifice plate can be fixed at this time. Since the spacing between the three sets of abutment devices 3 can be adjusted by the corresponding sliding devices 4, the three sets of abutment devices 3 can be used to fix orifice plates of different sizes, thereby improving the practicality of the processing positioning device to a certain extent.

[0030] like Figure 2 As shown, the sliding device 4 includes a slider 41 sliding on the slide groove 51, a threaded rod 42 for driving the slider 41 to slide, and a bearing seat 43 for supporting the threaded rod 42. The slider 41 is threadedly connected to the threaded rod 42. Bearing seats 43 are arranged at both ends of the threaded rod 42. Two sets of bearing seats 43 are arranged at the bottom of the support frame 5, and the two sets of bearing seats 43 are symmetrically arranged in the slide groove 51.

[0031] The two ends of the threaded rod 42 are respectively fixedly connected to the inner rings of the bearings in the two sets of bearing seats 43. The two sets of bearing seats 43 are fixedly connected to the bottom of the support frame 5, and the two sets of bearing seats 43 are symmetrically placed in the slide groove 51. The abutment device 3 is fixedly connected to the slider 41.

[0032] Due to the arrangement of the slider 41, the threaded rod 42 and the bearing seat 43, since the slider 41 is threadedly connected to the threaded rod 42, and the slider 41 slides on the slide groove 51, when the threaded rod 42 is rotated, the slider 41 can slide back and forth along the slide groove 51, thereby driving the supporting device 3 to move closer to the support block 2 or away from the support block 2.

[0033] like Figure 3 As shown, the abutting device 3 includes an arc-shaped baffle 31 for abutting against the orifice plate, a spring 32 for buffering the arc-shaped baffle 31, and a telescopic rod 33 for limiting the spring 32. The spring 32 is arranged around the telescopic rod 33. The telescopic end of the telescopic rod 33 is connected to the arc-shaped baffle 31. The other end of the telescopic rod 33 is connected to the slider 41.

[0034] The telescopic end of the telescopic rod 33 is fixedly connected to the arc-shaped baffle 31. The other end of the telescopic rod 33 is fixedly connected to the slider 41. One end of the spring 32 is fixedly connected to the arc-shaped baffle 31. The other end of the spring 32 is fixedly connected to the slider 41.

[0035] Due to the arrangement of the arc baffle 31, the spring 32 and the telescopic rod 33, when the slider 41 slides along the slide groove 51, the abutting device 3 moves toward the direction of the support block 2, and the arc baffle 31 in the abutting device 3 abuts against the orifice plate. When the three groups of arc baffles 31 abut against the orifice plate at the same time, and the three groups of arc baffles 31 move a certain distance toward the orifice plate again, the three groups of arc baffles 31 will be subjected to a certain extrusion force at the same time, and compress the corresponding spring 32 and the telescopic rod 33. At this time, the spring 32 in the compressed state will produce an equal reaction force on the arc baffle 31, so that the three groups of arc baffles 31 can be firmly abutted against the orifice plate, and the orifice plate can be fixed at this time. Through the arrangement of the spring 32, when the arc baffle 31 abuts against the orifice plate, the spring 32 has a certain buffering effect, and thus can play a certain protective role on the orifice plate. When the spring 32 is in a compressed state, the telescopic rod 33 can prevent the spring 32 from deforming, thereby protecting the spring 32 to a certain extent.

[0036] like Figure 2 As shown, the sliding device 4 further includes a threaded handle 44. The threaded handle 44 is arranged at one end of the threaded rod 42.

[0037] The threaded handle 44 is fixedly connected to one end of the threaded rod 42 .

[0038] Due to the provision of the threaded handle 44, the threaded rod 42 can be driven to rotate together by rotating the threaded handle 44, thereby facilitating the operation of the staff.

[0039] like Figure 3 As shown, the abutting device 3 further includes a rubber pad 34 . The rubber pad 34 is arranged on the arc-shaped baffle 31 .

[0040] A plurality of rubber pads 34 arranged in an arc-shaped array are fixedly connected to the arc-shaped baffle plate 31 .

[0041] Due to the provision of the rubber pad 34, when the arc baffle 31 abuts against the orifice plate, the rubber pad 34 on the arc baffle 31 will contact the orifice plate, thereby preventing the arc baffle 31 from causing unnecessary wear to the orifice plate, thereby providing a certain degree of protection for the orifice plate.

[0042] like Figure 4 As shown, the processing and positioning device for the crescent-shaped orifice plate also includes a damping block 6. A plurality of groups of damping blocks 6 arranged in a circular array are arranged on the top of the support block 2.

[0043] A plurality of groups of damping blocks 6 arranged in a circular array are fixedly connected to the top of the support block 2 .

[0044] Due to the setting of the damping block 6, when the orifice plate is placed on the support block 2, the damping block 6 on the support block 2 will contact the orifice plate, thereby increasing the friction between the support block 2 and the orifice plate, thereby preventing the orifice plate placed on the support block 2 from being displaced.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
