Description

Technical Field

[0001] The present invention relates to grinding equipment, in particular to a burr grinding equipment for an automobile washing pump housing. Background Art

[0002] Automobile washing pump housings are usually castings made of aluminum alloy. After casting and molding, burrs often remain at the parting surface position of the mold (usually the flange surface) of the automobile washing pump housing, which not only affects the appearance of the product but also causes difficulties in subsequent processing and assembly. Therefore, it is necessary to grind the above burrs. At present, the burr grinding on the surface of automobile washing pump housings is mainly manual grinding. The main reason is that the automobile washing pump housing is a product with an irregular external structure, and it is very difficult for ordinary manipulators to accurately clamp and transfer the automobile washing pump housing. That is, it is difficult to accurately place the automobile washing pump housing in the correct position onto the workbench of the automatic grinding equipment for automatic clamping. This leads to the problem that even if the automatic grinding equipment can complete the automatic grinding operation, the subsequent grinding will deviate due to inaccurate clamping of the automobile washing pump housing, and it is difficult to achieve automatic grinding operation for the automobile washing pump housing. The problem with manual grinding is that before each automobile washing pump housing is ground, workers need to manually fix the automobile washing pump housing on the workbench, which has a large labor intensity and very low efficiency.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0041] As shown Figure 1 in the figure is the automotive wash pump housing A that needs to have its burrs polished in this solution. It mainly includes an external housing A1 and a diversion channel A2 provided inside the housing. It should be noted that the diversion channel A2 extends radially from the edge of the housing to the center position of the housing A1 and then extends axially. The automotive wash pump housing in this solution cooperates with other components to assemble into a complete automotive wash pump.

[0042] As shown Figures 2 - 9 in the figure is a burr polishing device for an automotive wash pump housing, which includes a grinding machine 1, an alignment device 2, and a clamping and transfer device 3. Among them, the alignment device 2 is used to deflect the automotive wash pump housing placed by the worker on the first conveyor belt to an accurate position, and the clamping and transfer device 3 is used to clamp the deflected automotive wash pump housing and transfer it to the grinding machine 1 behind for the grinding machine to polish the burrs.

[0043] It should be noted that in this solution, the grinding machine 1 includes a main body 11 and a grinding mechanism 12 installed in the main body. Among them, the grinding mechanism is composed of an X-direction moving component, a Y-direction moving component, and a grinding head. When the automotive wash pump body is transferred to the grinding machine by the clamping and transfer device 3, the grinding head moves along the edge of the parting surface with burrs of the automotive wash pump body under the drive of the X-direction component and the Y-direction component, and the burrs on the automotive wash pump body are polished by the grinding head rotating at high speed on the head during the movement.

[0044] It should be noted that in this solution, the alignment device 2 is composed of the following parts. Specifically, it includes a conveying mechanism 21, two guide plates 22, a blocking mechanism 23, and a deflecting mechanism 24.

[0045] Among them, the conveying mechanism 21 includes a first support platform 211 that plays a supporting role. A first roller 212 is rotatably installed at both ends of the first support platform. A first motor 213 is coaxially connected to the shaft end of one of the two first rollers. The rotation of the first motor drives the connected first roller 212 as a driving roller to rotate, and a first conveyor belt 214 is also wound around the two first rollers. As shown Figure 5 in the figure, the middle position of the first conveyor belt 214 in this solution is separated to create an avoidance channel, and the width of the avoidance channel is exactly such that a tongue 242 can pass through, avoiding interference between the tongue and the first support platform 211 when the tongue extends from the bottom of the first support platform 211. It should also be noted that in this solution, the first conveyor belt slides over the upper surface of the first support platform, that is, the first support platform effectively supports the first conveyor belt so that it can still maintain a stable state when the first conveyor belt is subjected to a downward pressing force from above, avoiding irreversible elongation of the first conveyor belt after being stretched.

[0046] As shown Figure 5 in the figure, two guide plates 22 are fixedly installed on the first support table 211. The gap between these two guide plates gradually decreases from the incoming material side to the outgoing material side of the conveying mechanism 21 until it decreases to a width that only allows a car washing pump housing to slide through. Then, the rear baffle part extends parallelly. It should be noted that in this solution, the main purpose of setting the baffle in this way is to initially correct the car washing pump housing placed on the first conveyor belt through the two baffles, so that the car washing pump housing can enter the area where the rear blocking mechanism 23 is located in the correct posture. Preferably, in order to prevent the car washing pump housing from getting stuck between the two guide plates, that is, to avoid the car washing pump body being held by the two guide plates, the width between the two baffles is specified to be less than the diagonal length of the car washing pump housing. It should be noted that in this width, the situation where the two corners of the car washing pump housing are held by the two guide plates 22 can be effectively avoided. The specific reason is that in this width, after the car washing pump housing is placed between the two guide plates, if the car washing pump housing is temporarily held, it will also rotate due to uneven force on both sides until it rotates to the corrected state in the future.

[0047] The blocking mechanism 23 includes two guide rods 231. These two guide rods 231 are horizontally inserted on the first support table 211 of the conveying mechanism 21 and can slide towards both sides of the first support table when subjected to an axial force. As shown Figure 5 in the figure, two baffle plates 232 are fixedly installed on the inner ends of these two guide rods 231. The distance between these two baffle plates is the same as the distance between the parallel extension parts of the guide plates 22, that is, the two baffle plates respectively continue to extend along the parallel extension parts of the guide plates on their respective sides. At the same time, a first spring 233 is sleeved on each of the two guide rods. One end of this first spring abuts against the first support table of the conveying mechanism 21, and the other end abuts against the outer side surface of the baffle plate. When the force pushing the baffle plate outwards disappears, the baffle plate can retract to the initial position (the state flush with the guide plate). It should be noted that in this solution, the purpose of such a design is that when the car washing pump housing is deflected, the baffle plate needs to have the ability to avoid, and when the car washing pump housing enters between the blocking mechanisms, the baffle plate 232 needs to play a role in guiding and correcting.

[0048] As shown Figure 5As shown, the turning mechanism 24 is arranged directly above the baffle mechanism 23 to turn the automotive wash pump housing that enters the blocking mechanism 23 to an accurate state. Specifically, the automotive wash pump housing has a diversion channel A2 inside, and this diversion channel is raised and protruded within the automotive wash pump housing. Therefore, when clamping the automotive wash pump housing, it is necessary to avoid this raised diversion channel to prevent the clamping mechanism from hitting the diversion channel, that is, there is a directionality when clamping the automotive wash pump housing. For this reason, it is necessary to turn the automotive wash pump housing that enters the blocking mechanism 23 to keep its directionality consistent and avoid the problem that the position of the guiding flow channel A2 on the automotive wash pump body is inaccurate when the worker places the automotive wash pump body on the first conveyor belt 214.

[0049] As Figure 6 shown, the turning mechanism 24 includes a first telescopic cylinder 241 arranged below the first support platform. A retaining tongue 242 is connected to the telescopic part of the first telescopic cylinder. Driven by the first telescopic cylinder, the retaining tongue can pass through the first support platform 214 and the avoidance channel and then extend into the blocking mechanism 23 to block the automotive wash pump body that enters the blocking mechanism. At the same time, as Figure 6 shown, directly above the position where the blocking mechanism is located, a second telescopic cylinder 243 is also fixedly installed. The telescopic rod of the second telescopic cylinder can be inserted into the automotive wash pump body blocked by the retaining tongue 242. Specifically, the telescopic rod of the second telescopic cylinder 243 can be inserted into the diversion channel A2 that axially rises in the automotive wash pump body so that the automotive wash pump body can rotate around the telescopic rod of the second telescopic cylinder 243 as the center. In order to turn the automotive wash pump body to a unified state. A first gear 244 is rotatably installed on the telescopic rod of the second telescopic cylinder 243, and a movable dial rod 245 is connected to the first gear. At the same time, a fixed dial rod 246 is also installed on the telescopic rod of the second telescopic cylinder. The fixed dial rod and the movable dial rod are on the trajectories of two concentric circles with different diameters to avoid collision with the movable dial rod during the rotation process. In addition, as Figure 6 shown, a second motor 247 is also fixedly installed on the telescopic rod of the second telescopic cylinder. A second gear 248 is coaxially installed on the output shaft of the second motor. The second gear meshes with the first gear. By driving the second motor to rotate, the movable dial rod connected to the first gear is driven to rotate around the telescopic rod of the second telescopic cylinder. It should be noted that after the telescopic rod of the second telescopic cylinder is inserted into the diversion channel A2 of the automotive wash pump body, the movable dial rod driven by the second motor will rotate a certain angle until the movable dial rod and the fixed dial rod clamp the radially extending diversion channel, and at this time the automotive wash pump body is turned in place. In addition, it should also be noted that during the rotation of the automotive wash pump body, the two baffles in the blocking mechanism will retract adaptively to ensure the smooth completion of the rotation of the automotive wash pump body.

[0050] In addition, it should be noted that in order to enable the above-mentioned turning action to be automatically completed after the car washing pump body enters the blocking mechanism, a first proximity switch 249 is also installed on one of the baffles 232, and the first proximity switch is respectively connected to the first telescopic cylinder 241, the second telescopic cylinder 243 and the second motor by electrical signals. When the car washing pump body passes through the first proximity switch, the first proximity switch 249 is triggered, and then sends a signal to the first telescopic cylinder, the second telescopic cylinder and the second motor electrically connected thereto. After receiving the signal, the first telescopic cylinder drives the blocking tongue to extend into the blocking mechanism 23, and stops the car washing pump body at the set position. Then the second telescopic cylinder extends, and the telescopic rod of the second telescopic cylinder is inserted into the guide flow channel of the car washing pump body. Then the second motor rotates and drives the movable lever to rotate inside the housing of the car washing pump body with the telescopic rod of the second telescopic cylinder as the center. As the movable lever rotates a certain angle, the movable lever pushes the radially extending guide flow channel A2 in the car washing pump body to rotate the car washing pump body until the guide flow channel is clamped by the fixed lever and the movable lever. At this time, the car washing pump body rotates into place.

[0051] It should be noted that, as a preferred embodiment of the above, in order to prevent the movable lever and the fixed lever from hitting the misaligned guide channel A2 of the car washing pump body when following the telescopic rod of the second telescopic cylinder to descend, the fixed lever and the movable lever are both elastic telescopic rod structures that can be axially telescopic.

[0052] It should also be noted that in this solution, in order to facilitate the insertion of the telescopic rod of the second telescopic cylinder 243 into the guide channel of the automobile washing pump body, its diameter is usually 2 to 3 mm smaller than the inner diameter of the guide channel, so the movable lever will inevitably shake when the automobile washing pump body is moved. In order to improve the stability of the automobile washing pump body during rotation, the telescopic rod of the second telescopic cylinder 243 in this solution is a hollow structure. At the same time, a circle of airbags 2410 is also provided on the outside of the telescopic rod, and the airbags are connected to the internal hollow channel of the telescopic rod. At the same time, a piston 2411 is also inserted in a sliding fit inside the telescopic rod of the second telescopic cylinder, which drives the piston to extend into the telescopic rod so that the airbag swells and smoothly presses against the inside of the guide channel of the automobile washing pump body, thereby increasing the stability of the automobile washing pump body during rotation. It should be noted that a second spring 2412 is also installed inside the hollow channel of the telescopic rod, and the second spring abuts against the inner end face of the piston, so that when the second telescopic cylinder retracts, the second spring can push part of the piston out of the telescopic rod of the second piston cylinder, thereby deflated the airbag and ensure that the telescopic rod can easily withdraw from the guide flow channel A2 of the car washing pump body.

[0053] like Figure 7 , Figure 8As shown, the clamping and transfer device includes a guiding chute 31, a positioning and conveying mechanism 32, and a clamping mechanism 33.

[0054] Among them, the guiding chute 31 is arranged on the discharge side of the guiding mechanism 2 to receive the straightened automotive wash pump body. The positioning and conveying mechanism 32 is arranged on the discharge side of the guiding chute 32 to receive the automotive wash pump body that slides over from the guiding device via the guiding chute 32. It should be noted that the positioning and conveying mechanism has a positioning plate to enable the incoming automotive wash pump body to be positioned in the correct posture. The clamping mechanism 33 is arranged above the positioning and conveying mechanism 32 to clamp the automotive wash pump body located in the positioning and conveying mechanism and send the automotive wash pump body into the grinding machine 1 for grinding in an accurate posture.

[0055] It should be noted that the positioning and conveying mechanism in the above structure includes a second support platform 321. A second roller 322 is rotatably installed at both ends of the second support platform 321. One of the second rollers serves as a driving roller, and a third motor 329 is coaxially connected to the shaft end. At the same time, a second conveyor belt 323 is wound around the two second rollers 322. The second conveyor belt smoothly passes through the upper surface of the second support platform 321 to provide support for the second conveyor belt when the second conveyor belt is pressed. As Figure 7 、 Figure 8 shown, a number of positioning components are equally spaced and installed on the second conveyor belt. The positioning components are used to accurately position the automotive wash pump body transferred from the guiding device 2, providing guarantee for the subsequent accurate clamping of the clamping mechanism 33.

[0056] Specifically, as Figure 9 shown, the positioning component includes a base 324 fixedly installed on the second conveyor belt through a hinge. A positioning plate 325 is installed on the base. A cavity into which the automotive wash pump body can slide is formed on the upper surface of the positioning plate. In addition, as Figure 8 、 Figure 9As shown in the figure, one side edge of the positioning plate is hinged to one side edge of the base through a hinge. At the same time, the middle of the base is concave, and a third telescopic cylinder 326 is arranged in the concave part of the base. One end of the third telescopic rod is hinged to the base in a flippable manner, and the other end is hinged to the bottom surface of the positioning plate 325. When the third telescopic cylinder extends, it can drive the positioning plate to turn up, and then pour out and clean the incompletely positioned automotive washing pump body in the positioning plate, avoiding the clamping mechanism from hitting the misaligned automotive washing pump body during subsequent clamping. It should be noted that in the positioning assembly, in order to accurately judge whether the automotive washing pump body has been accurately positioned in the cavity of the positioning plate, at least one second proximity switch 327 is installed in the cavity of the positioning plate. The second proximity switch is electrically connected to the third telescopic cylinder. When the automotive washing pump body slides into the cavity in an accurate posture, all the second proximity switches are activated. After the third telescopic cylinder receives the signals sent by all the second proximity switches, it will not extend. When the posture of the automotive washing pump body falling into the positioning plate is inaccurate or not in place, some of the second proximity switches 327 will not be activated. At this time, the third telescopic cylinder will extend and drive the positioning plate to turn up to pour out the misaligned automotive washing pump body in the positioning plate 325.

[0057] It should be noted that as Figure 1 shown, in order to improve the positioning success rate of the automotive washing pump body in the positioning plate, a vibrator 328 is also arranged at the bottom of the second support platform. The vibrator vibrates the second support platform so that the positioning group passing above it also follows high-frequency vibration, thereby performing vibration adjustment on the automotive washing pump body in the positioning plate. It should be noted that in order to keep the vibration range within a reasonable range, the second support platform is divided into at least two parts, that is, one part (at the front) is the part where the vibrator is installed, and the other part (at the rear where the clamping mechanism needs to apply pressure for clamping) is the part without the vibrator installed.

[0058] As Figure 7 、 Figure 8As shown in the figure, in this solution, the clamping mechanism 33 includes a guide frame 331 that penetrates through the upper part of the main body 11. A moving part 332 that can move along the extension direction of the guide frame is installed on the guide frame. The moving part can be a roller-type moving structure, or a lead screw or gear-type moving structure. Below the moving part 332, a fourth telescopic cylinder 333 is provided. The telescopic rod of the fourth telescopic cylinder is a hollow structure, and a circle of sliders 334 is evenly distributed circumferentially on the rod wall at the end of the telescopic rod of the fourth telescopic cylinder 333. At the same time, a fifth telescopic cylinder 335 is also provided in the telescopic rod of the fourth telescopic cylinder. A push cylinder 336 is coaxially connected to the end of the telescopic rod of the fifth telescopic cylinder 335. The lower edge of the push cylinder has an inclined chamfer, and the slider is smoothly abutted against the chamfer. Then, as the push cylinder axially expands and contracts under the drive of the fifth telescopic cylinder, the slider can also radially expand and contract, thereby realizing the tensioning of the slider inside the housing A1 of the automotive wash pump body and achieving the clamping and fixing of the automotive wash pump body. It should be noted that, as Figure 4 shown, the automotive wash pump body in this solution has a directionality. In order to avoid the radially extending guide channels in the automotive wash pump body, corresponding avoidance grooves are provided at the end of the telescopic rod of the fourth telescopic cylinder and the lower part of the push cylinder.

[0059] Finally, it should be noted that when the push cylinder 336 retracts, in order to enable the push cylinder to drive the slider 334 to retract to ensure convenient insertion during the next clamping. The push cylinder and the slider are both magnetic and can attract each other to adsorb the slider to radially retract when the push cylinder retracts.

[0060] Working principle: When deburring the automotive wash pump body is required, the worker places the automotive wash pump body on the first conveyor belt with its open end facing upwards, and ensures that the automotive wash pump body can enter the guiding channel formed by two baffles. As the width of the guiding channel decreases, the automotive wash pump body driven by the first conveyor belt moves between the two guiding plates. During this period, the automotive wash pump body is guided by the two guiding plates to rotate to a state adapted to the width between the two guiding plates. At this time, the preliminary alignment and positioning of the automotive wash pump body are completed. Then, the automotive wash pump body enters the rear blocking mechanism. When the automotive wash pump body enters this mechanism, it is detected by the first proximity switch. The first proximity switch immediately drives the first telescopic cylinder to extend. After the tongue blocks the automotive wash pump body, the second telescopic cylinder in the turning mechanism descends and extends into the guiding flow channel of the automotive wash pump body. Then, the first telescopic cylinder retracts and resets. Then, the second motor rotates and drives the movable lever to push the radially extending part of the guiding flow channel in the automotive wash pump body, and the automotive wash pump body then rotates. During the rotation of the automotive wash pump body, the baffle retreats until the automotive wash pump body rotates into place. Then, the first telescopic cylinder extends again and blocks the automotive wash pump body. Then, the second telescopic cylinder retracts and resets, and the first telescopic cylinder also follows and resets. The automotive wash pump body that has been turned and aligned then enters the rear positioning assembly through the guiding groove. During this process, the vibrator vibrates to improve the success rate of the automotive wash pump body's positioning. And during this process, if the positioning of the automotive wash pump body fails, the second proximity switch set in the cavity of the positioning plate will be able to detect it, and drive the third telescopic cylinder electrically connected to it to extend and pour out the automotive wash pump body in the positioning assembly, avoiding the situation of collision between the automotive wash pump body and the clamping mechanism during subsequent clamping. And if the positioning is successful, the third motor drives the second conveyor belt to advance one station. At this time, the positioning assembly equipped with the automotive wash pump body comes below the clamping mechanism. After the clamping mechanism descends and clamps the automotive wash pump body, the fourth telescopic cylinder in the clamping mechanism retracts and drives the automotive wash pump body into the grinding machine. The grinding mechanism in the grinding machine then performs the deburring operation on the automotive wash pump body clamped by the clamping mechanism. When the grinding is completed, the clamping mechanism takes the automotive wash pump body out of the main body of the grinding machine and places it in the rear collection area, and the deburring operation is completed.
