Description

Technical Field

[0001] The utility model belongs to the technical field of the processing of impeller drainage automotive water pumps, and particularly relates to a composite locking tooling for the processing of impeller drainage automotive water pumps. Background Art

[0002] The impeller drainage automotive water pump is an impeller type drainage water pump used in automobiles. Its working principle is as follows: during the working process, the impeller drainage automotive water pump is used to pump water into working components that need to be cooled, such as an engine, for dissipating heat from high-temperature components such as the engine. The main structure of the impeller drainage automotive water pump includes a pump housing and an impeller press-fitted in the pump housing. The water pump is fixedly installed through a water pump bracket.

[0003] During the production and processing of the impeller drainage automotive water pump, first, the cast pump housing needs to be processed. Since the pump housing is a housing workpiece with a special-shaped structure, during the processing of the blank, in order to maintain the processing accuracy, the special-shaped pump housing needs to be placed on the tooling and locked.

[0004] After locking, a series of processing steps such as opening holes, grooving, and impeller press-fitting can be carried out on the pump housing. For small-sized water pumps, their housing sizes are small and are relatively easy to position. Usually, the pump housing is placed in the groove structure of the fixture and locked. For water pumps with slightly larger sizes, their pump housing sizes are also larger. For large-sized pump housings, it is not only difficult to lock and position them. Specifically, due to their large sizes, when locking, it is necessary to lock and press-position the entire circumference of the pump housing to prevent the pump housing from moving or shaking during the processing. It is indeed quite laborious to lock the pump housing workpiece with a high degree of special shape.

[0005] Moreover, due to the obvious differences in the sizes of the pump housings of different models of water pumps. Obviously, the existing locking methods of tooling fixtures, such as conventional locking structures like cylinders and pressure plates, not only cannot meet the locking requirements of pump housings with various different specifications and sizes during the locking process, but also it is very difficult for the locking structures on the tooling to lock pump housings with different models, specifications, and shapes once the shape and size of the pump housing change.

[0006] Therefore, during the actual working process, there are too many supporting toolings, and the processing of products is often diversified. Therefore, it is rather cumbersome and laborious to disassemble and replace the tooling during the processing. Even worse, once the shape of the pump body changes slightly, it is necessary to mold and process the supporting tooling. Summary of the Utility Model

[0007] Based on the above background, the purpose of the utility model is to provide a composite locking tooling for the processing of impeller drainage automotive water pumps.

[0008] To achieve the above purpose, the utility model adopts the following technical solutions:

[0009] An impeller drainage automotive water pump processing composite locking tooling, including a locking tooling table, and several pressing plate mechanisms are fixedly assembled and connected to the top edge part of the locking tooling table;

[0010] The pressing plate mechanism includes a hinged pressing plate seat, and the pressing plate seat is assembled and connected with a pressing tongue with adjustable spacing through several screw adjusting structures;

[0011] On both sides of the inner end of the pressing plate seat, lifting hinged seats are respectively hinged through hinge ears, a connecting shaft is fixedly connected between the lifting hinged seats, the pressing plate mechanism further includes a pushing sleeve sleeved on the connecting shaft, and a lifting cylinder is fixedly assembled and connected to the bottom of the pushing sleeve;

[0013] Preferably, the fixed bracket includes a U-shaped bracket part, and both sides of the outer end of the pressing plate seat are respectively hinged on the U-shaped bracket part through fixed pin shafts;

[0014] The bottom of the U-shaped bracket part is fixedly connected with a fixed base part fixedly installed at the top position of the locking tooling table.

[0015] Preferably, the upper end of the hinge ear is hinged on the side wall of the pressing plate seat through a pin shaft;

[0016] The lower end of the hinge ear is hinged on the outer side wall of the lifting hinged seat through a pin shaft.

[0017] Preferably, the screw adjusting structure includes a long screw fixedly connected to the pressing tongue, and the long screw penetrates through the pressing plate seat.

[0018] Preferably, the long screw is slidably connected to the pressing plate seat;

[0019] A pair of nuts positioned on the side walls on both sides of the pressing plate seat are threadedly connected to the long screw.

[0020] Preferably, a central limiting table column for limiting the water pump housing is fixedly connected to the top center part of the locking tooling table;

[0021] A pump housing pressing mechanism is installed on the top of the central limiting table column.

[0022] Preferably, the pump housing pressing mechanism includes a threaded column fixedly connected to the central limiting table column, a threaded ring sleeve is threadedly connected to the threaded column, and an annular flange seat is fixedly connected to the bottom of the threaded ring sleeve;

[0023] Several long pressing plates are assembled and connected to the annular flange seat, and a protrusion is integrally formed at the bottom of the outer end of the long pressing plate.

[0024] Preferably, the annular flange seat is provided with a plurality of guide openings, a long sliding screw slidably connected to the long pressure plate is fixedly connected in the guide opening, and a locking screw threadedly connected to the long sliding screw is threadedly connected to the long pressure plate.

[0027] The utility model has the following beneficial effects:

[0028] 1. During the working process, when the pump casing is loaded, the cylinder works, the piston rod of the cylinder descends and pulls the jacking hinge seat to flip and descend the pressure plate seat. During the flipping and descending process of the pressure plate seat, since the outer end of the pressure plate seat is hinged on the fixed bracket, the pressure plate seat in the flipped state carries the pressure tongue and presses down on the pump casing. Since the pressure tongue can adjust the spacing according to the size of the pump casing, its downward pressing position can be adjusted.

[0029] During the working process, it can lock pump casings of various models and specifications, and the locking stability is very high because of the circumferential locking pressure method.

[0030] 2. During the working process, the operator first rotates the threaded sleeve to adjust the threaded sleeve, annular flange seat-long pressure plate structure until the long pressure plate is pressed and locked on the pump housing after the spring is compressed (the top of the spring is not fixed).

[0031] During actual work, loosen the locking screw and slide the long pressure plate outward or inward to ensure that the long pressure plate can fully contact and press.

[0032] Since the threaded ring sleeve, annular flange seat-long pressure plate structure adopts threaded connection, the position of the long pressure plate can be adjusted after rotation to avoid blocking the processing position. This method can realize the pump casing locking pressure in the above top pressure method during the pump casing processing, solving the technical defects of high profile pump casing in the single-side processing process, which makes the pump casing unstable and easy to tilt and shake.

[0043] Embodiment 1

[0044] Such as Figures 1-5As shown in the figure, a composite locking tooling for processing an impeller drainage automotive water pump includes a locking tooling table 1 (the shape of the locking tooling table 1 is circular, and a number of mounting holes are opened on the locking tooling table 1 in the existing manner for mounting on the workbench surface of a lathe, such as fastening through the mounting holes and bolts). A number of pressing plate mechanisms 2 are fixedly assembled and connected to the top edge part of the locking tooling table 1.

[0045] In this way, the pressing plate mechanisms 2 of different models and specifications are locked in a surrounding locking manner, and this way realizes non-disassembly locking (the shapes of pump casings of the same type are not significantly different, and the projected shape of the pump casing on the horizontal plane is similar to a circle. Therefore, the pressing plate mechanisms 2 designed in a circumferential manner can lock and press regardless of the differences in the outer shapes of the pump casings as long as the main structure is circular. And because of the surrounding locking method, it can be adapted to lock and press pump casings of multiple models, specifications and sizes).

[0046] Specifically, the pressing plate mechanism 2 includes a pressing plate seat 21 arranged in a hinged manner. The pressing plate seat 21 is assembled and connected with a pressing tongue 22 with adjustable spacing through a number of screw adjusting structures. Specifically, the screw adjusting structure includes a long screw 2211 fixedly connected to the pressing tongue 22. The long screw 2211 passes through the pressing plate seat 21. The long screw 2211 is slidably connected to the pressing plate seat 21. A pair of nuts 221 positioned on the side walls on both sides of the pressing plate seat 21 are threadedly connected to the long screw 2211.

[0047] During the working process, the relative position between the pressing tongue 22 and the pump casing is adjusted according to the size of the pump casing. The specific method is: after loosening the nuts on both sides, slide and adjust the pressing tongue 22 until the pressing tongue 22 is located at the surrounding positions of the edge of the pump casing.

[0048] The two inner ends of the above-mentioned pressing plate seat 21 are respectively hinged with a jacking hinge seat 25 through hinge ears (the hinging method of the hinge ears is: the upper end of the hinge ear 251 is hinged on the side wall of the pressing plate seat 21 through a pin shaft; the lower end of the hinge ear 251 is hinged on the outer side wall of the jacking hinge seat 25 through a pin shaft).

[0049] A connecting shaft is fixedly connected between the jacking hinge seats 25 (the shape of the jacking hinge seat 25 is similar to a triangle). The pressing plate mechanism 2 further includes a pushing sleeve 241 sleeved on the connecting shaft. A jacking cylinder 24 is fixedly assembled and connected to the bottom of the pushing sleeve 241.

[0050] Specifically, a connecting screw is threadedly connected to the bottom of the pushing sleeve 241, and the connecting screw is threadedly connected to the piston rod of the cylinder 24.

[0051] A fixed bracket is hinged to the outer end of the pressing plate seat 21, and the fixed bracket is fixedly assembled at the top of the locking tooling table 1. The fixed bracket includes a U-shaped bracket part 231, and both sides of the outer end of the pressing plate seat 21 are respectively hinged to the U-shaped bracket part 231 through fixed pin shafts; the bottom of the U-shaped bracket part 231 is fixedly connected with a fixed base part 23 fixedly installed at the top of the locking tooling table 1 (the cylinder barrel of the air cylinder is fixedly installed at the top of the fixed base part 23).

[0052] During the working process, after the pump shell is loaded, at this time, the air cylinder 24 works, the piston rod of the air cylinder 24 descends and pulls the jacking hinge seat 25, turning the pressing plate seat 21 downwards. During the process of the pressing plate seat 21 turning downwards, since the outer end of the pressing plate seat 21 is hinged to the fixed bracket, therefore, the pressing plate seat 21 in the turned state drives the pressing tongue 22 to press down on the pump shell. Since the pressing tongue 22 can adjust the distance according to the size of the pump shell, its pressing position can be adjusted accordingly.

[0053] During the working process, it can lock the pump shells of multiple models and specifications, and due to the circumferential locking and pressing method, the locking stability is very high.

[0054] Embodiment 2

[0055] As Figures 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, a central limiting column 3 for limiting the water pump shell is fixedly connected to the central part of the top of the above-mentioned locking tooling table 1 (most automotive water pumps are general principle water pumps with the same structural principle, and the pump shell has mounting holes, and the central limiting column 3 penetrates through the mounting hole position).

[0056] Meanwhile, a pump shell top pressing mechanism is installed at the top of the central limiting column 3. The pump shell top pressing mechanism realizes locking the pump shell from the top (during the actual working process, according to the processing requirements, if it is necessary to process the top position of the pump shell, the pump shell top pressing mechanism does not need to be installed). During the side processing, due to the uneven force on the pump shell and the high degree of irregularity of the pump shell, this method can keep the pump shell in a further top pressing state, thereby maintaining a high stability.

[0057] Specifically, the pump casing pressing mechanism includes a threaded column 43 fixedly connected to the central limiting column 3, a threaded sleeve 41 is threadedly connected to the threaded column 43 (the center of the threaded sleeve 41 is a threaded hole for threaded connection), and an annular flange seat 42 is fixedly connected to the bottom of the threaded sleeve 41; a plurality of long pressure plates 44 are assembled and connected to the annular flange seat 42, and a protrusion is integrally formed at the bottom of the outer end of the long pressure plate 44. A plurality of guide openings are provided on the annular flange seat 42, and a long sliding screw 45 slidably connected to the long pressure plate 44 is fixedly connected in the guide opening (a cylindrical sliding cavity adapted to the long sliding screw 45 is provided on the long pressure plate 44), and a locking screw 451 locked on the long sliding screw 45 is threadedly connected to the long pressure plate 44 (the locking screw 451 penetrates into the cylindrical sliding cavity and squeezes on the long sliding screw 45). The threaded column 43 is sleeved with a spring 431 , the bottom of the spring 431 is fixedly connected to the top position of the central limiting column 3 ; the top of the spring 431 is supported at the bottom position of the annular flange seat 42 .

[0058] During the working process, the operator first rotates the threaded ring sleeve 41 to adjust the threaded ring sleeve 41, the annular flange seat 42-the long pressure plate 44 structure, until the spring 431 is compressed and the long pressure plate 44 is pressed and locked on the pump housing (the top of the spring 431 is not fixed).

[0059] In actual working process, after loosening the locking screw 451 , the long pressing plate 44 is slid outward or inward to adjust to ensure that the long pressing plate 44 can fully contact and press.

[0060] Since the threaded ring sleeve 41, the annular flange seat 42-long pressure plate 44 structure adopts a threaded connection method, the position of the long pressure plate 44 can be adjusted after rotation to avoid blocking the processing position. In this way, the pump casing is locked by the top pressure method during the processing of the pump casing, which solves the technical defects of the high profile pump casing being unstable and easy to tilt and shake during the processing of the pump casing on one side.

[0061] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
