Description

Combined tool for measuring quality of spare parts of metering pump

Technical Field

The utility model relates to the technical field of metering pump detection tools, in particular to a combination tool for detecting the quality of spare parts of a metering pump.

Background

The metering pump is an important device in a spinning workshop, and hundreds or even thousands of online metering pumps are generally configured for each spinning machine, so that the metering pump belongs to vulnerable devices in the spinning machines. The quick-wear parts such as the sealing element, the cross shaft, the safety piece and the like need to be replaced when a worker maintains the metering pump each time. The cross shaft and the safety disc are transmission parts of the metering pump, and the stress born by the two parts is larger; meanwhile, the two transmission parts are mutually matched, and the contact ends between the two transmission parts are easy to wear. Therefore, any one of the two parts is broken in the use process, so that the metering pump cannot work, and the whole set of new cross shaft and safety piece are required to be replaced by a vertical horse; otherwise, the normal operation of the whole spinning machine is affected.

At present, the cross axle and the safety disc of the metering pump are all in batch for delivery, and after the components are delivered, the staff needs to check and accept. The current acceptance means are mainly based on the evidence provided by suppliers or from appearance inspection, and the acceptance means cannot clearly judge the quality of each spare part. The patent with the publication number of CN209783795U discloses a carrier of a rotating shaft type torque force detection device for MIM metal pieces, the carrier of the rotating shaft type torque force detection device comprises a first substrate and a second substrate, a clamping groove is formed in one end of the first substrate, a first slot is formed in the other end of the first substrate, a second slot is formed in one end of the second substrate, two protruding ends are symmetrically arranged on the upper half of the second substrate, a first limiting block is arranged on the upper half of the first substrate, a limiting groove is formed in the surface of the first limiting block, a second limiting block is arranged on the lower half of the second substrate, and an inserting block is arranged on the surface of the second limiting block. The torsion detection device is strong in high-precision specification and use limitation, can effectively ensure the consistency and accuracy of torsion detection, is suitable for torsion measurement of various products, and is high in practicability. However, the method is only suitable for torsion tests of shafts, and cannot carry out strength tests on the safety disc, so that other detection equipment is required to be adopted to detect the safety disc independently, the whole test process is very troublesome, and the efficiency of the whole test is seriously affected. Therefore, a set of detection tool is urgently needed, whether the strength of the cross shaft and the strength of the safety disc meet the use requirement or not can be accurately judged in the spare part acceptance process, and the detection efficiency can be effectively improved.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1 to 4, a combination tool for detecting the quality of spare parts of a metering pump is used for fixing a cross shaft 10 and a safety disc 20 in the metering pump, the combination tool comprises a fixing base 30, a force transmission mechanism 40 and a force application seat 50, a mounting position 31 is arranged on the fixing base 30, and the safety disc 20 is mounted and fixed on the mounting position 31; one end of the force transmission mechanism 40 is movably inserted into the clamping hole of the safety disc 20; the other end of the force transmission mechanism 40 is provided with a convex strip 41, and one end of the cross shaft 10 is clamped on the convex strip 41; the force application seat 50 can be sleeved on the other end of the cross shaft 10, and a force application clamping slot 51 is arranged on the other end of the force application seat 50; the force application seat 50 cannot rotate relative to the cross shaft 10; the force application seat 50 can drive the force transmission mechanism 40 to transmit torsion force to the safety disc 20 on the fixed base 30 through the cross shaft 10; or both ends of the force transmission mechanism 40 can be matched with the fixed base 30 and the force application base 50 to respectively transmit torsion force to the rupture disc 20 and the cross shaft 10.

When the cross shaft 10 or the safety disc 20 is required to be detected independently, the utility model can be realized by combining the fixed base 30, the force transmission mechanism 40 and the force application seat 50 in pairs, and the utility model focuses on the condition of the combined test. When the combination test is performed, one cross 10 and one safety disc 20 are arbitrarily extracted from the same batch, and then the cross 10 and the safety disc 20 are placed on the whole combination tool in the installation mode, so that an operator can preliminarily judge the actual conditions of the cross 10 and the safety disc 20 through a torque wrench. The cross 10 and the safety disc 20 are directly connected and matched, so that in the actual use process, any damage to the cross 10 and the safety disc 20 leads to the failure of the metering pump, and damaged parts need to be replaced, therefore, in the combined test process, the damaged parts can be primarily judged to belong to the category which needs to be focused on by grouping, and retest is carried out after replacement of new damaged parts, if the cross 10 and the safety disc 20 can be kept stable under rated pressure, the quality level difference in the category which the damaged parts belong to before is indicated, and the parts of the category need to be tested independently. If there is still damage to the components in the cross 10 and the disc 20, then if the damaged component is still in the same category as the previously damaged component, it can basically be determined that the quality of the component in that category is most likely to be problematic, and it is necessary to test the component in that category separately; if the damaged component is still of a different class than the previously damaged component, the analysis is based on the results of other test groups, if necessary more than one more test group, or two products are tested individually.

In addition, in the present utility model, the fixing base 30 and the force applying base 50 may be fixed at the same time, and the force applying mechanism 40 may transmit the torsional force to the cross 10 and the rupture disc 20 at the same time by the force applying mechanism 40, so that the strength of the two components may be measured separately at the same time. Failure of either component does not affect the other component to continue testing and exert torsional forces. Therefore, in any test mode in actual operation, the strength of the cross 10 and the rupture disc 20 can be measured by the combination tool of the utility model, and the flexibility of the test is improved.

The combined tool for detecting the spare part quality of the metering pump utilizes the fixed base 30 as a stress base, so that the whole tool is convenient to clamp and fix; by designing the fixing base 30, the force transmission mechanism 40 and the force application seat 50, the safety disc 20 and the cross shaft 10 can be matched with each other and detected independently in actual operation; when the cross shaft 10 and the safety disc 20 are required to be detected simultaneously, the safety disc 20 is only required to be directly fixed on the fixed base 30, the external force application tool can drive the force transmission mechanism 40 to transmit torsion force to the safety disc 20 on the fixed base 30 while transmitting torsion force to the cross shaft 10 through the force application seat 50, so that the intensity of the safety disc 20 can be detected independently, the safety disc 20 and the cross shaft 10 can be detected simultaneously, the detection flexibility and efficiency are improved, and the whole detection process is simple and convenient.

The main purpose of the force transmission mechanism 40 according to the present utility model is to serve as a force transmission structure between the cross 10 and the rupture disc 20. In some possible implementations, the force transmission mechanism 40 is a force transmission rod or frame structure, which simplifies the structure, avoids direct contact between the cross 10 and the rupture disc 20, and facilitates fixing and maintaining the state of the cross 10 during the test.

In some possible implementation manners, in order to facilitate the later single-component test, the force transmission mechanism 40 comprises a force transmission clamping column 42, a first base 43 and a second base 44, wherein opposite ends of the first base 43 and the second base 44 are respectively provided with a clamping hole 45, the other ends of the first base 43 and the second base 44 are respectively provided with a convex strip 41, and two ends of the force transmission clamping column 42 are respectively inserted into the clamping holes 45 of the first base 43 and the second base 44; the protruding strips 41 on the first base 43 are clamped in the clamping holes of the safety plate 20, and the protruding strips 41 on the second base 44 are clamped on the corresponding ends of the cross shaft 10. In the present embodiment, the first base 43 and the second base 44 are substantially identical in structure, which is convenient for use and storage at a later stage. The main purpose of the above-mentioned clamping hole 45 is to facilitate the insertion of the action end of the external torque wrench when the component is separately detected, thereby improving the convenience of use. Meanwhile, in some improved embodiments, the fixing base 30 and the force application seat 50 are fixed at the same time, and then a worker twists the force transmission clamping column 42 through the torque wrench, so that the cross shaft 10 and the safety disc 20 can be subjected to independent test at the same time by applying force in two directions, and the convenience of the test is improved. In this embodiment, the fixing base 30 and the force application base 50 have the same function, so that the two structures can be designed in the same structure.

In some possible implementations, in order to facilitate the separate test, the first base 43 and the second base 44 are each provided with a force application hole 46 or a clamping position 47, so that the external force application device can clamp or rotate.

In some possible implementations, in order to facilitate the provision of chamfers on the end surfaces of the first and second bases 43, 44 at the ends where the ribs 41 are provided, such a design reduces the sharp edges thereof, which can effectively protect the staff and the components of the test.

Referring to fig. 1 and 3, in order to facilitate the force transfer mechanism 40 to have enough space to move and to be able to be effectively clamped into the rupture disc, the fixing base 30 is provided with two avoidance holes 32, and the mounting positions 31 are respectively arranged on the opposite areas of the fixing base 30 outside the avoidance holes 32. Wherein, both ends of the rupture disc 20 are respectively fixed on the two mounting positions 31, so that the clamping holes on the rupture disc 20 are positioned in the area of the avoiding holes 32, and thus, the corresponding end of the force transmission mechanism 40 can be effectively inserted into the clamping holes on the rupture disc 20.

In the modification of the above embodiment, in order to facilitate fixing of the rupture disc 20, the mounting position 31 is provided with a locking screw 33, and the locking screw 33 locks the rupture disc 20.

In addition, in order to facilitate the external substrate clamping and securing of the fixing base 30, an anti-slip structure 34 is provided on the outer wall of the fixing base 30. In the present utility model, the anti-slip tooth structure is preferable, and the fixing base 30 is designed in a circular ring shape, so that the external clamping workbench can be conveniently clamped in any direction. In addition, in some embodiments, the fixing base 30 may be mounted on the ground or a firm external fixture, and in this case, the fixing base 30 may be designed with a plurality of mounting fixing holes and fastened to the ground or the firm external fixture by bolts.

Referring to fig. 4, when the strength test is performed on the cross 10 and the rupture disc 20 at the same time, the fixing base 30, the force transmission mechanism 40, the cross 20 and the force application seat 50 are all arranged in a straight line, collapse is easy to occur during the test, for this purpose, in order to maintain the stability of the whole test, in one embodiment of the present utility model, the fixing base 30 is provided with a support frame 35, the support frame 35 is provided with a bearing plate 36, the bearing plate 36 is provided with a movable perforation 38, and the force transmission mechanism 40 is movably arranged on the movable perforation 38. The main function of the bearing plate 36 is to support the limit force transmission mechanism 40, so that the limit force transmission mechanism is kept in a vertical state with the rupture disc 20, and is convenient for transmitting torsion. In addition, during actual use, the fixing base 30 can be integrated with the force application seat 50 through the supporting frame 35, so that an operator can transmit torsion acting force to the cross shaft 10 and the safety disc 20 through the force transmission mechanism 40.

In some possible implementations, in order to effectively protect the force transfer mechanism 40 from abrasion due to excessive friction with the movable aperture 38 during rotation, the movable aperture 38 is sleeved with the movable sleeve 37, and the force transfer mechanism 40 is movably sleeved in the movable sleeve 37.

The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
