Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a testing device for manufacturing pump body castings. Background Technology

[0002] Pump body casting inspection equipment is a key device used to evaluate the casting quality of pump bodies. It covers multiple dimensions of inspection, including dimensional accuracy, internal defects, mechanical properties and sealing performance, to ensure the reliability of products under high pressure and high load conditions.

[0003] A patent document with publication number CN220323016U discloses a hardness testing device for pump body casting. The device includes an equipment platform, a casting clamping unit, and a testing unit. The equipment platform is a rectangular plate. The casting clamping unit includes a middle platform, a spacing adjustment hydraulic cylinder, a mounting plate, a rotating shaft, a clamping hydraulic cylinder, a clamping plate, and a buffer plate. The left and right sides of the middle platform are respectively fixedly connected to the sides of the spacing adjustment hydraulic cylinder. The far end of the spacing adjustment hydraulic cylinder is respectively fixedly connected to the bottom end of the mounting plate. The bottom end of the mounting plate is respectively rotatably connected to both ends of the rotating shaft. The clamping hydraulic cylinder clamps the pump body casting from the outside or supports it from the inside to achieve the clamping purpose. Then, the hardness of the main body is detected by a two-dimensional sliding downward pressure hardness tester. It can clamp various types of pump bodies and can detect multiple positions of the pump body.

[0004] The above-mentioned solution uses a casting clamping unit to clamp the casting and provide it with a rotational function to facilitate multi-point inspection. However, this solution is difficult to provide stable positioning for the rotor casting in the pump body casting. Furthermore, in the existing technology, when performing hardness testing on the sidewall of the rotor casting, it is placed horizontally for limitation, which lacks a circumferential limiting function. This may cause circumferential displacement during the extrusion testing of the rotor casting, affecting the testing work. Moreover, when it is necessary to inspect the end of the rotor casting, the rotor generally includes a rotor body and a corresponding shaft end. When inspecting the shaft end of the rotor casting, the rotor body is usually placed on a worktable. However, when it is necessary to inspect the end position of the rotor body, the rotor shaft end is not sufficiently aligned for support, and it is easy to tip over. This inspection work lacks a suitable positioning component to meet its inspection requirements.

[0005] To address these issues, the present invention proposes a testing device for pump body casting manufacturing. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are: The present invention discloses a testing device for manufacturing pump body castings, comprising a workbench and a frame mounted on the workbench. A control slide rail is mounted on the top of the frame, and a testing mechanism is mounted on the control slide rail. The testing mechanism tests the rotor casting. A testing positioning mechanism is mounted on the workbench, comprising a first testing positioning component and a second testing positioning component. The first testing positioning component is connected to a support plate, which is symmetrically mounted on the workbench. For the inspection of pump body rotor castings, when it is necessary to lay the rotor castings horizontally for inspection of their side walls, a first inspection and positioning component is set up to provide a clamping and positioning, and then the inspection mechanism is used for inspection.

Therefore, for the inspection of pump body rotor castings, the pump body rotor castings are stably limited by setting a first inspection and positioning component and a second inspection and positioning component on the worktable. The appropriate inspection and positioning component is selected according to the inspection requirements of the pump body rotor castings; it has excellent working flexibility. Furthermore, the first detection and positioning component and the second detection and positioning component do not affect each other. That is, after the first detection and positioning component limits the pump body rotor casting, the second detection and positioning component will not affect the pump body rotor casting when the detection mechanism detects it. Similarly, after the second detection and positioning component limits the pump body rotor casting and the detection and processing are carried out, the first detection and positioning component will not affect the detection work after it is reset.

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 - Appendix Figure 13 A testing device for manufacturing pump body castings includes a workbench 1 and a frame 2 set on the workbench 1. A control slide rail 3 is set on the top of the frame 2 and a testing mechanism 4 is set on the control slide rail 3. The testing agency 4 tests the rotor casting, which includes a rotor casting body 6 and a shaft end piece 61 provided at one end of the rotor casting body 6. A keyway 62 is also provided at the end side of the shaft end piece 61. The workbench 1 is equipped with a detection and positioning mechanism, which includes a first detection and positioning component and a second detection and positioning component. The first detection and positioning component is connected to the support plate 5, which is symmetrically arranged on the workbench 1.

[0022] According to the appendix Figure 1 - Appendix Figure 3 and appendix Figure 6 - Appendix Figure 9As shown, when it is necessary to horizontally position the rotor casting for inspection of its sidewalls, the first inspection and positioning component is used to provide clamping and positioning, and then the inspection mechanism 4 is used for inspection.

[0023] To prevent circumferential displacement of the rotor casting, this solution uses a first auxiliary component to cooperate with the keyway 62 at the end of the shaft end piece 61 on the rotor casting body 6 to provide a stable positioning, thus avoiding circumferential displacement during inspection and improving the quality of the inspection work.

[0024] Combined with the appendix Figure 4 - Appendix Figure 6 and appendix Figure 10 - Appendix Figure 13 As shown, when it is necessary to inspect the end of the rotor casting, that is, to perform extrusion inspection on the bottom end face of the rotor casting body 6 or the end face of the shaft end piece 61, the second detection and positioning component is provided to provide a position limiting effect. Especially when it is necessary to provide support for the rotor casting body 6 through the shaft end piece 61, the shaft end piece 61 is inserted into the placement groove 1003 in the support column 1001, and then the second auxiliary component is used to cooperate with the keyway 62 on the shaft end piece 61 to provide a limiting effect.

[0025] For the inspection of pump body rotor castings, this solution uses a first inspection and positioning component and a second inspection and positioning component on the workbench to stably limit the pump body rotor casting. The appropriate inspection and positioning component is selected according to the inspection requirements of the pump body rotor casting; it has excellent working flexibility.

[0026] From the appendix Figure 2 - Appendix Figure 3 and appendix Figure 7 - Appendix Figure 9 As shown, the first detection and positioning component includes a rotary motor 701 disposed on one side of the support plate 5 and a connecting plate 702 connected to the rotary motor 701; a clamping cylinder 703 is disposed on one side of the connecting plate 702 and a clamping cover plate 704 is disposed at one end of the clamping cylinder 703; a limiting cylinder 705 is disposed at equal intervals on the side of the clamping cover plate 704 and a limiting clamping block 706 is disposed at the end of the limiting cylinder 705.

[0027] In other words, when it is necessary to inspect the side wall of the rotor casting, the rotor casting needs to be laid horizontally. Then, the rotor casting is provided with a horizontal clamping by the cooperation of the clamping cylinder 703 and the clamping cover plate 704. That is, the clamping cylinder 703 pushes the clamping cover plate 704 until one of the clamping cover plates 704 contacts and squeezes the end of the rotor casting body 6, and the other clamping cover plate 704 contacts and squeezes the end of the shaft end piece 61. Then, the limiting cylinder 705 set on the side of the clamping cover plate 704 pushes the limiting clamping block 706 to clamp and position the end side wall of the rotor casting body 6 and the end side wall of the shaft end piece 61 respectively.

[0028] To prevent the rotor casting from shifting circumferentially, this solution includes a first auxiliary component in one of the clamping covers 704; that is, the clamping cover 704 that contacts and presses the shaft end piece 61 includes the first auxiliary component.

[0029] The first auxiliary component includes an extension 801 fixedly disposed inside one of the clamping covers 704. An adjusting screw 802 is threadedly connected to the extension 801, and one end of the adjusting screw 802 extends to the outside of the clamping cover 704. One end of the adjusting screw 802 is connected to an auxiliary bearing 803, which is fitted into the top of a connecting body 804. The connecting body 804 is movably disposed in the extension 801. A handle body 805 is fixedly disposed at the other end of the adjusting screw 802, and a locking nut 806 is threadedly connected to the adjusting screw 802. At the bottom of the connector 804, there is a mounting slot 807 and a first magnetic piece 808 is embedded in the mounting slot 807; the mounting slot 807 is adapted to be inserted into the mating block 902; the mating block 902 is fixedly mounted on the top of the support block 901, and a second magnetic piece 903 that attracts the first magnetic piece 808 is embedded in the mating block 902; a locking protrusion 904 is fixedly mounted at the bottom of the support block 901; and auxiliary ramps 905 are symmetrically arranged on both sides of the bottom of the locking protrusion 904.

[0030] In other words, when clamping and limiting the shaft end piece 61, it is necessary to ensure that the keyway 62 on the shaft end piece 61 is aligned with the locking protrusion 904 at the bottom of the bearing block 901. After the limiting cylinder 705 pushes the limiting clamping block 706 to clamp the end side of the shaft end piece 61, the control screw 802 is rotated by the handle body 805, so that the control screw 802 pushes the connecting body 804. The connecting body 804 then pushes the locking protrusion 904 at the bottom of the bearing block 901 to engage with the keyway 62 on the shaft end piece 61, thereby providing a locking effect for the rotor casting and preventing circumferential positional displacement. Finally, the locking nut 806 is tightened to lock the control screw 802.

[0031] Combined with appendix Figure 6 and appendix Figure 8 - Appendix Figure 9 As shown, auxiliary ramps 905 are symmetrically arranged on both sides of the bottom end of the card protrusion 904. The purpose of setting the auxiliary ramps 905 here is to better adapt to keyways 62 of different sizes.

[0032] In other words, if the width of the keyway 62 is equal to the width of the protrusion 904, the protrusion 904 will directly engage with the keyway 62; if the width of the keyway 62 is slightly smaller than the width of the protrusion 904, the protrusion 904 does not need to be replaced. The auxiliary ramps 905 on both sides of the bottom of the protrusion 904 help the protrusion 904 engage with the keyway 62, providing better working flexibility and adaptability.

[0033] However, when the width of the keyway 62 is greater than the width of the retaining protrusion 904, the retaining protrusion 904 does not make close contact with its inner wall when it enters the keyway 62, and there is a possibility of it becoming loose. Therefore, the retaining protrusion 904 needs to be replaced.

[0034] Therefore, the connection between the carrier block 901 and the connector 804 is achieved by inserting the mating block 902 into the mounting slot 807, and by positioning the first magnetic piece 808 and the second magnetic piece 903 through mutual attraction. This makes it very convenient to replace the card protrusion 904 and facilitates subsequent disassembly, replacement and other maintenance work.

[0035] From the appendix Figure 4 - Appendix Figure 6 and appendix Figure 10 - Appendix Figure 13 As shown, when it is necessary to inspect the end of the rotor casting, that is, to inspect the end of the rotor casting body 6 or the shaft end piece 61, this solution uses a second detection and positioning component to achieve the limit.

[0036] The second detection and positioning component includes a support column 1001 and a mounting base 1002 fixedly disposed on the bottom side of the support column 1001. The mounting base 1002 is fixed to the worktable 1 by screws. A shaft end placement groove 1004 is provided through the support column 1001 along the axial direction, and a placement groove 1003 is provided at the top opening of the shaft end placement groove 1004. The opening of the placement groove 1003 is circular, and its diameter is equal to the end diameter of the rotor casting body 6. The opening of the shaft end placement groove 1004 is also circular, and its diameter is equal to the end diameter of the shaft end piece 61.

[0037] When it is necessary to perform extrusion testing on the end of the shaft end piece 61, the bottom end of the direct rotor casting body 6 can be placed in the placement groove 1003 at the top of the support column 1001.

[0038] If it is necessary to inspect the end of the rotor casting body 6, the shaft end piece 61 is inserted into the shaft end placement slot 1004 of the support column 1001 to provide a stable support for the rotor casting body 6 and prevent it from tilting.

[0039] Furthermore, this solution also includes a second auxiliary component, the purpose of which is to provide an anti-displacement solution for the circumferential direction of the rotor casting when the shaft end piece 61 is inserted into the shaft end placement slot 1004.

[0040] The bottom end of the through groove 1004 at the shaft end is also provided with a mounting slot 1005; the second detection and positioning component also includes a second auxiliary component.

[0041] The second auxiliary component includes a mounting plate 1101 that is adapted to and snaps into the mounting slot 1005, and the mounting plate 1101 is fixed by screws; a support cylinder 1102 is fixedly disposed on the mounting plate 1101 and a limiting strip 1103 is movably disposed in the support cylinder 1102; a first auxiliary spring 1104 is fixedly disposed at the bottom end of the limiting strip 1103, and the other end of the first auxiliary spring 1104 is fixedly disposed in the support cylinder 1102.

[0042] In other words, the circumferential anti-offset effect is provided by the engagement of the limit strip 1103 with the keyway 62 on the shaft end piece 61.

[0043] Auxiliary inclined surfaces 1201 are symmetrically arranged on both sides of the limiting strip 1103. The purpose of setting the auxiliary inclined surfaces 1201 is to better adapt to keyways 62 of different sizes.

[0044] Here, a guide pin 1202 is movably disposed at the top of the limiting strip 1103, and a second auxiliary spring 1203 is fixedly disposed at the bottom end of the guide pin 1202. The other end of the second auxiliary spring 1203 is fixedly disposed in the limiting strip 1103. The purpose of setting the guide pin 1202 here is to provide a guiding function for the engagement of the limiting strip 1103 and the keyway 62, so as to avoid the need for repeated operations to complete the engagement.

[0045] That is, after the second auxiliary component is installed, the top of the guide pin 1202 set on the top of the limit clip 1103 will be flush with the top opening of the shaft end placement groove 1004. When inserting the shaft end piece 61 into the shaft end placement groove 1004, it is also necessary to ensure that the limit clip 1103 and the keyway 62 are smoothly engaged. However, since the limit clip 1103 is in the shaft end placement groove 1004, after the shaft end piece 61 enters the shaft end placement groove 1004, the operator cannot observe the position of the limit clip 1103 and the keyway 62. Therefore, in order to improve the convenience of its engagement operation, this solution sets the guide pin 1202 on the top of the limit clip 1103.

[0046] When aligning the end of the shaft end piece 61 with the opening of the shaft end placement slot 1004, it is also necessary to align the guide pin 1202 with the keyway 62. Then, as the shaft end piece 61 enters the shaft end placement slot 1004, the guide pin 1202 enters the keyway 62. Then, the rotor casting is slowly lowered. Under the action of the rotor casting's own weight, the guide pin 1202 contacts the inner wall of the keyway 62. Then, as the rotor casting descends, the keyway 62 squeezes the guide pin 1202 until the guide pin 1202 enters the limiting strip 1103. Then, the limiting strip 1103 will engage with the keyway 62, making the operation highly convenient.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
