Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and more specifically, to a mixer paddle detection device. Background Technology

[0002] In existing mixers, such as dual planetary mixers, the mixing blade is typically installed as the final step in the assembly process, and the clearance between the mixing blade and other components is measured before the final commissioning stage. If, during this process, it is discovered that the mixing blade, due to its dimensions or other factors, interferes with other components or fails to meet design requirements, it needs to be removed for repair. This interrupts the entire assembly process, affecting the overall assembly schedule. Furthermore, because it occurs as the final step in the assembly process, it has a significant impact on the overall assembly of the mixer. Workshop workers' jobs are suspended, which in turn affects the overall work schedule and can even severely impact the entire project's progress. Utility Model Content

[0003] The main objective of this invention is to provide a stirring paddle testing device to solve the problem that stirring paddles in the prior art cannot be effectively tested before assembly.

[0004] To achieve the above objectives, this utility model provides a stirring paddle detection device, comprising: a base having multiple mounting positions; an outer frame assembly connected to the base, at least a portion of the outer frame assembly being movably disposed at different mounting positions, the outer frame assembly having a measuring part for engaging with the stirring paddle to be detected; a transmission assembly mounted on the base, the transmission assembly engaging with the stirring paddle to be detected and driving the stirring paddle to rotate; and a flexible member provided on the peripheral side and / or measuring part of the stirring paddle to be detected, the flexible member deforming under the action of the stirring paddle when the transmission assembly drives the stirring paddle to rotate.

[0005] Furthermore, the outer frame assembly includes: a support frame connected to a base; a connecting rod connected to the support frame and extending radially along the impeller to be tested; and a measuring column connected to the connecting rod, extending axially along the impeller to be tested, with the peripheral side of the measuring column located on the periphery of the impeller to be tested and serving as a measuring part.

[0006] Furthermore, the connecting rod has a length indicator, the measuring column is movably connected to the connecting rod, and the installation position on the connecting rod can be switched.

[0007] Furthermore, the support frame is located above the base, and the support frame and the base together form an installation area for mounting the impeller to be tested, with at least a portion of the transmission assembly located within the installation area.

[0008] Furthermore, the top of the support frame has a mounting groove, the middle part of the connecting rod is embedded in the mounting groove, the top of the measuring column is connected to the connecting rod, and the bottom of the measuring column is a free end.

[0009] Furthermore, the base has a groove, and the bottom of the support frame is slidably disposed in the groove to change the size of the installation area. The side of the groove has indicator information for indicating the installation position of the support frame.

[0010] Furthermore, there are multiple measuring columns, and measuring columns are set on both sides of the connecting rod.

[0011] Furthermore, the transmission assembly includes: a first gear rotatably mounted on a base; and a second gear meshing with the first gear, the second gear having a connecting shaft for driving the stirring paddle under test, the second gear driving the stirring paddle under test to rotate via the connecting shaft.

[0012] Furthermore, there are multiple first gears, at least some of which are of different sizes, and each first gear is replaceably mounted on the base. There are multiple second gears, and each first gear is provided at a position symmetrical to the first gear in the circumference. The ends of the stirring paddles to be tested on the symmetrical second gears can be installed perpendicular to each other.

[0013] Furthermore, the mounting position includes a first mounting position and a plurality of second mounting positions, the second mounting positions being arranged circumferentially and / or radially along the first mounting position, the first gear being disposed at the first mounting position, and the second gear being disposed at the second mounting positions in interchangeable positions.

[0014] By applying the technical solution of this utility model, the outer frame assembly, transmission assembly, and flexible component work together. The transmission assembly drives the impeller under test to rotate, simulating its use on a mixer. The outer frame assembly and flexible component work together to detect the rotation gap of the impeller. The installation position of the outer frame assembly on the base can be adjusted as needed to simulate the external components of the impeller in actual use. The flexible component serves a measurement purpose. It can be applied to the measuring part and / or the outer side of the impeller under test. When the impeller under test rotates under the drive of the transmission assembly, the interaction between the impeller and the measuring part causes the flexible component to undergo plastic deformation. At this time, the flexible component is located between the impeller and the measuring part, so its thickness reflects the gap between them. By measuring the thickness of the flexible component, the required gap can be characterized, and it can be determined whether the gap meets the installation requirements. If it does not meet the requirements, the impeller under test can be further inspected, which is convenient and quick. The above methods allow for effective testing of the agitator before formal assembly, ensuring that its dimensions and other features meet requirements during subsequent formal assembly. This avoids discrepancies that could affect the assembly progress and effectively guarantees the assembly schedule of the mixer. Attached Figure Description

[0026] To address the problem that existing technologies cannot effectively inspect stirring paddles before assembly, this invention provides a stirring paddle inspection device.

[0027] like Figures 1 to 5 The impeller testing device shown includes a base 10, an outer frame assembly 20, a transmission assembly 30, and a flexible element 40. The base 10 has multiple mounting positions. The outer frame assembly 20 is connected to the base 10, and at least a portion of the outer frame assembly 20 is repositionably disposed at different mounting positions. The outer frame assembly 20 has a measuring section for engaging with an impeller 50 to be tested. The transmission assembly 30 is mounted on the base 10 and engages with the impeller 50 to be tested, and is used to drive the impeller 50 to rotate. The flexible element 40 is provided on the peripheral side and / or measuring section of the impeller 50 to be tested. When the transmission assembly 30 drives the impeller 50 to rotate, the flexible element 40 deforms under the action of the impeller.

[0028] This embodiment utilizes the cooperation between the outer frame assembly 20, the transmission assembly 30, and the flexible component 40. The transmission assembly 30 drives the impeller 50 under test to rotate, simulating its use on a mixer. The outer frame assembly 20 and the flexible component 40 cooperate to detect the rotational clearance of the impeller 50. The mounting position of the outer frame assembly 20 on the base 10 can be adjusted as needed to simulate the external components of the impeller 50 during actual use. The flexible component 40 serves a measurement purpose, measuring the distance between the measuring part and / or the impeller 50 under test. The outer side of the measuring part can be coated with a flexible element 40. When the impeller 50 to be tested rotates under the drive of the transmission assembly 30, the interaction between the impeller 50 and the measuring part causes the flexible element 40 to undergo plastic deformation. At this time, the flexible element 40 is located between the impeller 50 and the measuring part, so that the thickness of the flexible element 40 can reflect the gap between the impeller 50 and the measuring part. By measuring the thickness of the flexible element 40, the required gap can be characterized, and then it can be determined whether the size of the gap meets the installation requirements. If it does not meet the requirements, the impeller 50 to be tested can be further inspected directly, which is convenient and quick. In this way, the impeller can be effectively inspected before formal assembly, so as to ensure that its shape and size meet the requirements when the impeller is formally assembled, avoiding the situation that the assembly progress is affected by non-compliance in the later assembly, and effectively ensuring the assembly progress of the mixer.

[0029] Optionally, the specific type of flexible component 40 can be selected as needed. In this embodiment, modeling clay is used as the flexible component 40. Modeling clay is inexpensive and can undergo plastic deformation, thus meeting the measurement requirements. Figure 5 As shown. At the same time, the setting position of the flexible member 40 can also be adjusted as needed. It can be set only on the outside of the stirring paddle 50 to be tested, or only at the measuring part, or both of the above locations, as long as it can ensure that the flexible member 40 deforms when the stirring paddle 50 to be tested passes through the measuring part.

[0030] like Figure 1 and Figure 2As shown, in this embodiment, the outer frame assembly 20 includes a support frame 21, a connecting rod 22, and a measuring column 23. The support frame 21 is connected to the base 10 and serves as the main body of the outer frame assembly 20, playing a supporting and connecting role. The connecting rod 22 is connected to the support frame 21 and extends radially along the stirring paddle 50 to be tested, thereby enabling the installation of the measuring column 23. The measuring column 23 is connected to the connecting rod 22 and extends axially along the stirring paddle 50 to be tested. The peripheral side of the measuring column 23 is located on the peripheral side of the stirring paddle 50 to be tested and serves as a measuring part. In this way, the measuring column 23 can simulate the component on the mixer that has a clearance fit with the outside of the stirring paddle, thereby enabling the measurement of the clearance at the outside of the stirring paddle.

[0031] like Figure 3 As shown, the support frame 21 in this embodiment adopts the form of a gantry frame. The support frame 21 is set above the base 10 and includes two parts: a crossbeam and columns. The columns are connected to the base 10 and extend longitudinally. Multiple columns can be provided. The crossbeam is connected to the top of the columns and extends laterally, thereby enabling the installation of the connecting rod 22 and ensuring the stable and reliable position of the measuring column 23. The columns and crossbeams form a gate-shaped structure, thus forming an installation area together with the base 10 at the bottom. The installation area is used to install the stirring paddle 50 to be tested. At least a part of the transmission assembly 30 can also be installed in the installation area, thereby facilitating cooperation with the stirring paddle 50 to be tested.

[0032] like Figure 2 As shown, in this embodiment, an installation groove 211 is provided at the middle position of the upper surface of the crossbeam of the support frame 21. The length direction of the installation groove 211 is set at an angle to the length direction of the crossbeam. The middle part of the connecting rod 22 is embedded in the installation groove 211. In this way, the crossbeam and the connecting rod 22 form an X-shaped structure. The measuring column 23 is arranged longitudinally and passes through the connecting rod 22. The top of the measuring column 23 and the connecting rod 22 form a limiting fit relationship to realize the connection between the two. The bottom end of the measuring column 23 is a certain distance away from the base 10 to form a free end.

[0033] In this embodiment, a length marker is provided on the connecting rod 22. The measuring column 23 is movably connected to the connecting rod 22. Multiple through holes are provided on the connecting rod 22, spaced apart along its length. The top of the measuring column 23 is designed with a larger diameter section than the others, creating a stepped structure below the top section. When the measuring column 23 is inserted into the through hole, the stepped structure abuts against the upper edge of the through hole, thus suspending the measuring column 23 on the connecting rod 22. When the model or specifications of the stirring paddle 50 to be tested change, the measuring column 23 can be installed in different through holes, allowing the measuring column 23 to be switched on the connecting rod 22 as needed, thereby achieving adaptability to different specifications.

[0034] Optionally, the number of measuring columns 23 can be set as needed, and can be one or more. In this embodiment, two measuring columns 23 are provided, and the two measuring columns 23 are respectively set on opposite sides of the connecting rod 22. The two measuring columns 23 are symmetrically set at the position of the mounting groove 211, so that the stirring paddle 50 to be tested can cooperate with the measuring columns 23 on both sides to ensure accurate and reliable measurement.

[0035] In this embodiment, the base 10 has a sliding groove 11. The bottom of the support frame 21, that is, the bottom end of the column, is slidably disposed within the sliding groove 11. This allows the installation position of the column to be adjusted according to the specifications of the stirring paddle 50 to be tested, thereby changing the size of the installation area and enabling the outer frame assembly 20 to adapt to stirring paddles of different specifications. Simultaneously, this embodiment provides indicator information on the side of the sliding groove 11 to indicate the installation position of the support frame 21. This indicator information, along with the aforementioned length markings, can be scales or similar information, facilitating personnel in determining the specific installation position and ensuring proper positioning and adjustment.

[0036] To further improve the adjustment range of the installation area, the number of columns can be increased as needed. The columns can be divided into multiple groups of two, with columns of the same length in the same group, which can be used simultaneously. The columns in different groups have different heights, so that when the height of the outer frame component 20 needs to be adjusted, columns from different groups can be replaced. This allows the installation area to be adjusted not only in the horizontal length but also in the vertical height, thereby further improving the adjustment range of the installation area and enhancing its adaptability to specifications.

[0037] like Figure 1 and Figure 2As shown, in this embodiment, the transmission assembly 30 adopts the form of a planetary gear set, thereby enabling it to more realistically simulate the use scenario of a mixer. Specifically, the transmission assembly 30 includes a first gear 31 and a second gear 32. The first gear 31 is rotatably mounted on the base 10 and is located approximately at the center of the base 10. The second gear 32 is located on the periphery of the first gear 31 and meshes with it. The second gear 32 has a connecting shaft 33 for transmission engagement with the stirring paddle 50 to be tested. The connecting shaft 33 can be in the form of a key structure, that is, the circumferential side of the connecting shaft 33 has a protrusion. When the connecting shaft 33 passes through the stirring paddle 50 to be tested, the transmission engagement with the stirring paddle 50 to be tested can be achieved through the protrusion. Thus, when the first gear 31 rotates under the drive of an external drive component, the first gear 31 drives the second gear 32 to rotate, and the second gear 32 can drive the stirring paddle 50 to rotate through the connecting shaft 33 thereon, thereby simulating the rotation of the stirring paddle.

[0038] In this embodiment, there are multiple first gears 31, and at least some of the first gears 31 are of different sizes. Each first gear 31 is replaceably installed on the base 10, so that different sizes of first gears 31 can be installed and replaced according to different specification requirements, thereby making it compatible with the specifications of the stirring paddle 50 to be tested.

[0039] In this embodiment, there are multiple second gears 32, and each second gear 32 is symmetrically positioned around the first gear 31. This embodiment uses two second gears 32. The reason for using a planetary gear set and a double gear configuration is that this embodiment primarily targets the impellers on a dual planetary mixer. Since there are two impellers 50 to be tested, there are also two second gears 32. Both second gears 32 mesh with the first gear 31 simultaneously, allowing both impellers 50 to be tested to be mounted onto the two second gears 32 at the same time, enabling simultaneous testing of both impellers 50. When mounting the two impellers 50, the ends of the impellers 50 on the symmetrical second gears 32 are mounted perpendicular to each other, resulting in a 90-degree circumferential difference between the two impellers 50. This means that one impeller rotates 90 degrees circumferentially from the position of the other impeller, which better suits the usage scenario of a dual planetary mixer. Of course, the specific arrangement of the second gears 32 can be adjusted as needed. For mixers with a single impeller, only one second gear 32 may be used.

[0040] Meanwhile, the second gear 32 in this embodiment is also arranged in groups. The second gears 32 in the same group are installed on the base 10 for use. The second gears 32 in different groups are not completely the same size, so that when the first gear 31 is replaced, the second gear 32 can also be replaced as needed, so as to cooperate with the first gear 31 and achieve the adaptation to different specifications of stirring paddles.

[0041] In this embodiment, to accommodate the interchangeable arrangement of the first gear 31 and the second gear 32, the mounting positions include a first mounting position and a second mounting position, both of which can be in the form of mounting holes. The first mounting position is used to mount the first gear 31; that is, the first gear 31 is positioned at the first mounting position. Since the first gear 31 may have different sizes, its mounting position remains unchanged, so only one first mounting position is required. The second mounting position is used to mount the second gear 32. Since the mounting position of the second gear 32 can change, multiple second mounting positions are provided, and these second mounting positions are arranged circumferentially and / or radially along the first mounting position. This allows the second gear 32 to be positioned at the second mounting position as needed, achieving adjustment of the second gear 32's mounting position and thus adapting to the specifications of the stirring paddle.

[0042] The stirring paddle detection device in this embodiment also includes bearings. Bearings can be installed between the first gear 31 and the base 10, and between the second gear 32 and the base 10, so that the gears can rotate smoothly.

[0043] The specific usage process of the impeller detection device in this embodiment is as follows:

[0044] 1. Select the correct transmission component 30 and install it on the base 10 according to the model of the stirring paddle to be tested;

[0045] 2. Install the two agitators to be tested onto the connecting shaft 33 of the second gear 32, ensuring that they are installed according to actual usage conditions, and that the two agitators are installed at a 90-degree angle. Figure 4 As shown;

[0046] 3. Select and adjust the support frame 21 of the outer frame assembly 20 according to the size of the selected model to ensure that it does not interfere with the rotation of the stirring paddle;

[0047] 4. Install the connecting rod 22 according to the size of the selected model, and insert the measuring column 23 into the corresponding through hole;

[0048] 5. Apply modeling clay to the stirring paddle 50 and measuring column 23 respectively, rotate the stirring paddle at a constant speed for one revolution, and leave a mark on the modeling clay. Remove the modeling clay and measure the "thickness" to obtain the gap of the stirring paddle. The gap can be used to determine whether the stirring paddle is qualified.

[0049] It should be noted that "multiple" in the above embodiments refers to at least two.

[0050] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0051] 1. This solves the problem that the stirring paddle cannot be effectively inspected before assembly in existing technologies;

[0052] 2. Effective testing can be carried out before the agitator is formally assembled, so as to ensure that the dimensions and other aspects of the agitator meet the requirements when it is formally assembled. This avoids the situation where non-compliance occurs in the later assembly and affects the assembly progress, thus effectively ensuring the assembly progress of the mixer.

[0053] 3. Different sized parts can be installed and replaced according to different specifications, thus adapting to the specifications of the stirring paddle to be tested, and thus having better adaptability;

[0054] 4. The test can be performed on the two agitators on the dual planetary mixer.
