Description

TECHNICAL FIELD

[0001] The utility model relates to a point gumming equipment technical field especially relates to a wheel body inner circle gumming machine. BACKGROUND

[0002] The wall surface of the inner circle of wheel bodies such as hub motor hubs, motor housings and the like needs to be brushed with glue for bonding magnetic steel sheets. In the past, the inner circle of these wheel bodies was either manually brushed or brushed using a glue throwing method. Manual brushing has poor uniformity of the thickness of the glue layer and is also slow. The glue throwing method is fast but only suitable for brushing glue with low viscosity. For hubs and the like that do not have a retaining ring or a retaining groove (both of which can be used to position the magnetic steel sheets), the inner circle is a smooth wall surface. In order to improve the positioning ability of the magnetic steel sheets, glue with high viscosity needs to be used. At this time, the glue throwing method is no longer suitable and a new glue brushing process is urgently needed. SUMMARY

[0034] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further detailed in combination with the drawings and examples.

[0035] As Figures 1-10 shown, the utility model discloses a wheel-shaped body 60 inner circle gluing machine, it includes frame 10, clamping drive mechanism, gluing mechanism 40 and glue supply mechanism, clamping drive mechanism, gluing mechanism 40 and glue supply mechanism all are set up on frame 10. Clamping drive mechanism is used for clamping wheel-shaped body 60, so that wheel-shaped body 60 can be positioned and limited, simultaneously clamping drive mechanism still drives wheel-shaped body 60 to rotate (self-rotation), glue supply mechanism is used for supplying glue to gluing mechanism 40, when wheel-shaped body 60 rotates, the inner circle wall surface (that is the area needing to be coated with glue) of wheel-shaped body 60 passes through the glue outlet 451 of gluing mechanism 40 in turn in each place, thereby realizes the gluing of wheel-shaped body 60 inner circle. In the case, take wheel-shaped body 60 is wheel hub as example and explain.

[0036] The clamping driving mechanism comprises a pressing roller 21, two positioning rollers 22, a pressing driving assembly 24 and a rotating driving member 23. The pressing roller 21 and the positioning rollers 22 are arranged in an isosceles triangle on the same numerical plane, and the rotating center axes of the pressing roller 21 and the positioning rollers 22 are parallel to each other. The distance between the pressing roller 21 and the two positioning rollers 22 is always equal. The two positioning rollers 22 are rotationally connected to the rack 10 and are arranged at intervals. The rotating driving member 23 is an electric motor (or a combination of an electric motor and a speed reducer), and drives any one of the positioning rollers 22 to rotate. The pressing driving assembly 24 is arranged in height on the rack 10, and drives the pressing roller 21 to move up and down, that is, to move towards the two positioning rollers 22. In order to avoid bruising the wheel body 60, the pressing roller 21 is also rotationally connected to the pressing driving assembly 24. Of course, the rotating driving member 23 can also drive the two positioning rollers 22 to rotate synchronously, and a linkage gear or belt can be added, or even a special rotating driving member 23 for driving the pressing roller 21 can be added, which will not be listed one by one.

[0037] The pressing driving assembly 24 comprises a guide rail 25, a pushing table 26, a mounting table 27, a driving module 28 and an equal-height screw 29. The guide rail 25 is arranged vertically in height on the rack 10. The pushing table 26 and the mounting table 27 are both slidingly connected to the guide rail 25, and the mounting table 27 is above the pushing table 26. The pressing roller 21 is rotationally connected to the mounting table 27. The equal-height screw 29 passes through the pushing table 26 and the mounting table 27, and a through hole is arranged on the pushing table 26 for the equal-height screw 29 to pass through. An elastic member is optionally arranged between the pushing table 26 and the mounting table 27. One end of the elastic member abuts against the mounting table 27, and the other end of the elastic member abuts against the pushing table 26. The elastic member is preferably a spring, and corresponds to the equal-height screw 29 one by one. The spring can be sleeved on the equal-height screw 29. The elastic member is preferably arranged to play a buffering role and avoid rigid collision. The driving module 28 is a pneumatic cylinder or a hydraulic cylinder. The pneumatic cylinder or the hydraulic cylinder pushes the pushing table 26 to move. According to the stroke of the pneumatic cylinder, the extension length of the push rod can be controlled within a certain range to ensure the normal use of the pneumatic cylinder. Therefore, the use of the above-mentioned pressing driving assembly 24 can make the clamping driving mechanism adapt to wheel bodies 60 within a certain size (outer diameter size) range, thereby improving the compatibility of the machine. The action of the hydraulic cylinder is relatively gentle, and the stroke is controllable, so that the clamping driving mechanism can also adapt to wheel bodies 60 within a certain size (outer diameter size) range. As an alternative, the driving module 28 comprises an electric motor and a screw rod. The screw rod is parallel to the guide rail 25, and is threadedly connected to the mounting table 27. The electric motor drives the screw rod to rotate. Such an arrangement can also improve the compatibility of the machine.

[0038] The clamping driving mechanism with the above arrangement is simple in structure, and the wheel body 60 is positioned and clamped by three points (the pressing roller 21 and the positioning rollers 22). The wheel body 60 is not easy to fall off after being clamped stably, and the wheel body 60 is vertically placed, and the two positioning rollers 22 can well support the wheel body 60, facilitating the feeding and positioning of the wheel body 60. After the wheel body 60 is pressed by the pressing roller 21, the positioning roller 22 is driven to rotate, so that the wheel body 60 is easily driven to rotate, and the operation is convenient. The clamping driving mechanism clamps the wheel body 60, so that the coating surface of the glue applying mechanism 40 is a plane, and the glue applying mechanism 40 is more uniform in glue discharging.

[0039] The glue supply mechanism includes a screw type pressure disc pump 31 and a glue barrel 32 for containing glue. The screw type pressure disc pump 31 cooperates with the glue barrel 32 to pump the glue in the glue barrel 32 to the glue applying mechanism 40. The screw type pressure disc pump 31 is a prior art and will not be described herein again. The glue barrel 32 can be a special glue barrel 32 or an original glue barrel 32 for glue. The glue supply mechanism with the above arrangement can conveniently and accurately realize pressure boosting and glue supply, and can be suitable for high-viscosity glue.

[0040] The glue applying mechanism 40 includes a glue discharging head 45, a high-pressure one-way valve 44 and a displacement assembly. The displacement assembly includes a lifting moving module 41, a horizontal moving module 42 and a buffer module. The lifting moving module 41 is arranged on the rack 10, and drives the horizontal moving module 42 to move up and down. The horizontal moving module 42 drives the buffer module to move relative to the clamping driving mechanism. The lifting moving module 41 and the horizontal moving module 42 are both linear moving modules based on motors, which are prior arts and will not be described herein again. The buffer module is used to provide a buffer in the vertical direction (or the direction of the glue discharging opening 451). The buffer module can have the following structure, which includes a sliding rail 431, a sliding block 432 and a spring pin 433. The sliding rail 431 is vertically fixed on the movable part of the horizontal moving module 42. The sliding block 432 is slidingly connected to the sliding rail 431. A limiting block is arranged on the movable part of the horizontal moving module 42 or the sliding rail 431 to limit the sliding block 432 from being removed from the sliding rail 431. The spring pin 433 is arranged on the limiting block above the sliding block 432. The high-pressure one-way valve 44 is fixed on the sliding block 432, and the glue discharging head 45 is connected to the outlet 33 of the high-pressure one-way valve 44 through a hard pipe, so that the glue discharging head 45 is also fixed and installed, and the glue discharging head 45 and the high-pressure one-way valve 44 move synchronously. By arranging the displacement assembly, the glue discharging head 45 can be temporarily away from the clamping driving mechanism when the wheel body 60 is loaded or unloaded, so as to avoid interference. In addition, by controlling the moving distance of the displacement assembly, the glue applying mechanism 40 can be better adapted to wheel bodies 60 of different specifications.

[0041] The glue outlet head 45 comprises a glue head body 46 and a glue head cover plate 47, the glue head body 46 is provided with a glue uniformizing groove 462 and a glue inlet 461, one end of the glue inlet 461 is communicated with the outlet 33 of the high-pressure one-way valve 44, the inlet of the high-pressure one-way valve 44 is communicated with the glue supply mechanism (the outlet 3333 of the screw type pressure disc pump 31), the other end of the glue inlet 461 is communicated with the glue uniformizing groove 462. The setting of the high-pressure one-way valve 44 ensures the smooth glue outlet, so as to better use the glue with high viscosity. The glue uniformizing groove 462 is located on the side of the glue head body 46, the glue head cover plate 47 is detachably connected with the side of the glue head body 46 through screws, and the glue head cover plate 47 blocks the glue uniformizing groove 462. At least one flow guide groove 471 is arranged on the side of the glue head cover plate 47 close to the glue uniformizing groove 462, the flow guide grooves 471 are arranged side by side and pass through the bottom edge of the glue head cover plate 47 in one direction, the flow guide grooves 471 are communicated with the glue uniformizing groove 462, and the flow guide grooves 471 and the side wall of the glue head body 46 cooperatively form the glue outlets 451. In order to make the glue disperse and flow to each glue outlet 451 more quickly and uniformly, and ensure uniform glue coating, a flow guide block 463 for guiding the glue is further arranged in the glue uniformizing groove 462. The glue outlet head 45 arranged in this way has good glue outlet uniformity, and by replacing the glue head cover plates 47 with different numbers of flow guide grooves 471, it can be used to adapt to wheel-shaped bodies 60 of different depths (for example, the wheel hub of the wheel hub motor of the electric vehicle, the shape of the electric vehicle determines the radial size of the wheel hub, if it is necessary to increase the power of the wheel hub motor, the depth of the wheel hub often has to be increased). In addition, by detaching the glue head cover plate 47, the glue outlet head 45 can be conveniently cleaned and maintained.

[0042] In addition, the guide assembly is arranged on the glue outlet head 45, and the guide assembly comprises a top block 48, a mounting block 49, an adjusting screw, a clamping screw and a guide wheel 4a.

The glue outlet head 45 is provided with a positioning slide 472, the length direction (vertical direction) of the positioning slide 472 is parallel to the direction of the glue outlet 451, the mounting block 49 is provided with a positioning block 491 which is in sliding cooperation with the positioning slide 472 and a long hole 492 which is matched with the adjusting screw, the long hole 492 is parallel to the positioning slide 472, and the adjusting screw is threadedly connected to the glue outlet head 45 through the long hole 492. The positioning slide 472 can ensure the stability of the movement of the mounting block 49, and further ensure that the guide wheel 4a reliably contacts the inner ring of the wheel body 60. The top block 48 is arranged on the side of the mounting block 49 away from the guide wheel 4a, the clamping screw is threadedly connected to the top block 48, the top block 48 is provided with a threaded hole 481 matched with the clamping screw, the clamping screw can extend out of the bottom of the top block 48 and abut against the mounting block 49. When the displacement assembly drives the glue outlet head 45 to extend into the inner ring of the wheel body 60 in the clamping driving mechanism, the guide wheel 4a first contacts the inner ring of the wheel body 60, and can always abut against the inner ring of the wheel body 60, so that the glue coating process is smoother. In addition, by adjusting the depth of the clamping screw screwed into the top block 48, the upper limit of the guide wheel 4a can be positioned, and the distance between the glue outlet 451 and the inner ring of the wheel body 60 is limited, so that the required glue coating thickness is obtained, and the uniformity of the glue coating is ensured.

[0043] The working principle of the utility model is: the wheel body 60 is placed on the two positioning rollers 22 by manual or feeding device, and then the pressing roller 21 is pressed, so that the wheel body 60 is clamped.
