Description

Technical Field

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

[0002] The car washing pump housing is usually a casting made of aluminum alloy. After casting, the car washing pump housing is located at the parting surface of the mold (usually the flange surface) and often has burrs, 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 burrs. The existing car washing pump housing surface burr grinding is mainly done manually. The main reason is that the car washing pump housing is a product with irregular external structure. It is difficult for ordinary manipulators to accurately clamp and transfer the car washing pump housing, that is, it is difficult to send the car washing pump housing with accurate position to 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 be deviated due to the inaccurate clamping of the car washing pump housing, and the automatic grinding operation of the car washing pump housing is difficult to achieve. The problem of manual grinding is that each car washing pump housing needs to be manually fixed on the workbench by workers before grinding, which is labor-intensive and inefficient.

DETAILED DESCRIPTION

[0038] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are 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 therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figure 1 The automobile washing pump housing A that needs to be polished is shown in this solution. It mainly includes an external housing A1 and a guide channel A2 arranged in the housing. It should be noted that the guide channel A2 extends radially from the edge of the housing to the center of the housing A1, and then extends axially. The automobile washing pump housing in this solution cooperates with other components to assemble into a complete automobile washing pump.

[0042] like Figures 2~9 The burr grinding device for the automobile washing pump housing shown in the figure comprises a grinder 1, a guide device 2 and a clamping and transferring device 3. The guide device 2 is used to turn the automobile washing pump housing placed on the first conveyor belt by the worker to the correct position, and the clamping and transferring device 3 is used to clamp the adjusted automobile washing pump housing and transfer it to the rear grinder 1 for the grinder to grind the burrs.

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

[0044] It should be noted that, in this solution, the guiding device 2 is composed of the following parts: specifically, a conveying mechanism 21 , two guide plates 22 , a blocking mechanism 23 and a turning mechanism 24 .

[0045] The conveying mechanism 21 includes a first support platform 211 for supporting, and a first roller 212 is rotatably mounted at each end of the first support platform. A first motor 213 is coaxially connected to the shaft end of one of the two first rollers. The first motor rotates to drive the first roller 212 connected thereto to rotate as an active roller, and a first conveying belt 214 is wound around the two first rollers. Figure 5 As shown, the first conveyor belt 214 in this solution is separated in the middle to make way for an escape passage, the width of which is just enough for a tongue 242 to pass through, so as to avoid interference between the tongue 242 and the first support platform 211 when the tongue 242 extends from the bottom. 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 the first conveyor belt can still maintain a stable state when it is subjected to downward pressure from the upper part, so as to avoid irreversible elongation of the first conveyor belt after being pulled.

[0046] like Figure 5 As shown, two guide plates 22 are fixedly mounted on the first support platform 211, and the gap between the two guide plates gradually decreases from the incoming material side to the outgoing material side of the conveying mechanism 21, until it is reduced to a width that only allows one car washing pump housing to slide through, and the rear baffle part extends in parallel. It should be noted that in this scheme, the baffle is set in this way, and its main purpose is to implement preliminary correction of 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 a correct posture. As a preference, in order to prevent the car washing pump housing from being stuck between the two guide plates as much as possible, that is, to prevent the car washing pump body from being supported 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 under this width, the situation where the two corners of the car washing pump housing are supported by the two guide plates 22 can be effectively avoided. The specific reason is that under this width, after the automobile washing pump housing is placed between the two guide plates, if the automobile washing pump housing is temporarily supported, it will subsequently rotate due to uneven force on both sides until it rotates to the correct state.

[0047] The blocking mechanism 23 includes two guide rods 231, which are inserted horizontally on the first support platform 211 of the conveying mechanism 21 and can slide toward both sides of the first support platform when subjected to axial force. Figure 5 As shown, two baffles 232 are fixedly installed on the inner ends of the two guide rods 231, and the spacing between the two baffles is the same as the spacing of the parallel extension part of the guide plate 22, that is, the two baffles continue to extend along the parallel extension part of the guide plate on their side. At the same time, a first spring 233 is also sleeved on the two guide rods, one end of which abuts on the first support platform of the conveying mechanism 21, and the other end abuts on the outer side of the baffle. When the force pushing the baffle outward disappears, the baffle can retreat to the initial position (the state flush with the guide plate). It should be noted that in this solution, the purpose of adopting such a design is that when the automobile washing pump housing is turned, the baffle needs to have the ability to avoid, and when the automobile washing pump housing enters between the blocking mechanisms, the baffle 232 needs to play a guiding role.

[0048] like Figure 5As shown, the turning mechanism 24 is arranged just above the baffle mechanism 23 to turn the car washing pump housing entering the blocking mechanism 23 to an accurate state. Specifically, the car washing pump housing has a guide channel A2 inside, and the guide channel is raised and protruded inside the car washing pump housing. Therefore, when clamping the car washing pump housing, it is necessary to avoid the raised guide channel to prevent the clamping mechanism from hitting the guide channel, that is, the car washing pump housing is directional when clamped. Therefore, it is necessary to turn the car washing pump housing entering the blocking mechanism 23 to keep its directionality consistent, so as to avoid the problem of inaccurate position of the guide channel A2 on the car washing pump body when the worker places the car washing pump body on the first conveyor belt 214.

[0049] like Figure 6 As shown, the turning mechanism 24 includes a first telescopic cylinder 241 disposed below the first support platform, and a blocking tongue 242 is connected to the telescopic portion of the first telescopic cylinder. The blocking tongue, driven by the first telescopic cylinder, can pass through the first support platform 214 and the avoidance channel and extend into the blocking mechanism 23, thereby blocking the car washing pump body entering the blocking mechanism. Figure 6 As shown, a second telescopic cylinder 243 is fixedly installed just above the position of the blocking mechanism, and the telescopic rod of the second telescopic cylinder can be inserted into the car washing pump body blocked by the blocking tongue 242. Specifically, the telescopic rod of the second telescopic cylinder 243 can be inserted into the axially raised guide channel A2 of the car washing pump body, so that the car washing pump body can rotate around the telescopic rod of the second telescopic cylinder 243. In order to rotate the car washing pump body to a unified state. A first gear 244 is also rotatably installed on the telescopic rod of the second telescopic cylinder 243, and a movable lever 245 is connected to the first gear. At the same time, a fixed lever 246 is also installed on the telescopic rod of the second telescopic cylinder. The fixed lever and the movable lever are on the trajectory lines of two concentric circles of different diameters to avoid collision with the movable lever during the rotation process. In addition, as Figure 6 As shown, a second motor 247 is also fixedly mounted on the telescopic rod of the second telescopic cylinder, and a second gear 248 is coaxially mounted on the output shaft of the second motor, and the second gear is meshed with the first gear. The second motor is driven to rotate to drive the movable lever connected to the first gear to rotate around the telescopic rod of the second telescopic cylinder. It should be noted that when the telescopic rod of the second telescopic cylinder is inserted into the guide channel A2 of the automobile washing pump body, the movable lever driven by the second motor will rotate a certain angle until the movable lever and the fixed lever clamp the radially extending guide channel, and the automobile washing pump body is turned into place. In addition, it should be noted that during the rotation of the automobile washing pump body, the two baffles in the blocking mechanism will adaptively retreat to ensure the smooth completion of the rotation of the automobile washing 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 transferring device includes a guide slot 31 , a positioning and conveying mechanism 32 and a clamping mechanism 33 .

[0054] The guide chute 31 is arranged on the discharge side of the guide mechanism 2 to receive the adjusted car washing pump body. The positioning and conveying mechanism 32 is arranged on the discharge side of the guide chute 32 to receive the car washing pump body that slides from the guide device through the guide chute 32. It should be noted that the positioning and conveying mechanism has a positioning plate to position the entering car washing pump body in a correct posture. The clamping mechanism 33 is arranged above the positioning and conveying mechanism 32 to clamp the car washing pump body in the positioning and conveying mechanism and send the car washing pump body into the grinder 1 in an accurate posture for grinding.

[0055] It should be noted that the positioning conveying mechanism in the above structure includes a second support platform 321, and a second roller 322 is rotatably mounted at both ends of the second support platform 321, wherein one of the second rollers is used as a driving roller and is coaxially connected to a third motor 329 at the shaft end. At the same time, a second conveyor belt 323 is wound around the two second rollers 322, and the second conveyor belt smoothly passes through the upper surface of the second support platform 321, so as to provide support for the second conveyor belt when the second conveyor belt is under pressure. Figure 7 , Figure 8 As shown, a plurality of positioning components are installed at equal intervals on the second conveyor belt, and the positioning components are used to accurately position the automobile washing pump body transferred from the guiding device 2, so as to provide guarantee for the subsequent clamping mechanism 33 to implement accurate clamping.

[0056] Specifically, Fig. 9 As shown, the positioning assembly includes a base 324 fixedly mounted on the second conveyor belt by a hinge, and a positioning plate 325 is mounted on the base. A cavity is formed on the upper surface of the positioning plate so that the car washing pump body can slide into it. In addition, as Figure 8 , Fig. 9As shown, 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 and can be flipped, and the other end is hinged to the bottom surface of the positioning plate 325. When the third telescopic cylinder is extended, it can drive the positioning plate to flip up, and then pour out and clean up the car washing pump body that is not fully positioned in the positioning plate, so as to avoid the collision between the clamping mechanism and the car washing pump body that is not in the correct position during the subsequent clamping. It should be noted that in the positioning assembly, in order to accurately determine whether the car washing pump body has been accurately positioned in the cavity of the positioning plate, at least one second proximity switch 327 is also installed in the cavity of the positioning plate. The second proximity switch is connected to the electrical signal of the third telescopic cylinder. When the car washing pump body slides into the cavity with an accurate posture, all the second proximity switches are activated, and the third telescopic cylinder will no longer extend after receiving the signals sent by all the second proximity switches. When the car washing pump body falls into the positioning plate inaccurately 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 flip up and pour the car washing pump body that is not in place out of the positioning plate 325.

[0057] It should be noted that if Figure 1 As shown, in order to improve the success rate of the car washing pump body in the positioning plate, a vibrator 328 is also arranged at the bottom of the second support platform, and the vibrator vibrates the second support platform to make the positioning group passing above it also vibrate at high frequency, thereby implementing vibration adjustment on the car 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 is installed with the vibrator (in the front part), and the other part is not installed with the vibrator (in the part where the rear clamping mechanism needs to be pressed and clamped).

[0058] like Figure 7 , Figure 8As shown, in this scheme, the clamping mechanism 33 includes a guide frame 331 passing through the upper part of the main body 11, and 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 screw rod or a gear type moving structure. Below the moving part 332, a fourth telescopic cylinder 333 is arranged, and the telescopic rod of the fourth telescopic cylinder is a hollow structure. A circle of sliders 334 are evenly distributed 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 arranged in the telescopic rod of the fourth telescopic cylinder, and the end of the telescopic rod of the fifth telescopic cylinder 335 is coaxially connected with a push cylinder 336. The lower edge of the push cylinder has an inclined chamfer, and the slider is smoothly abutted against the chamfer. When the push cylinder is axially extended and retracted under the drive of the fifth telescopic cylinder, the slider can also be radially extended and retracted, thereby realizing that the slider is tightened inside the housing A1 of the automobile washing pump body, and the automobile washing pump body is clamped and fixed. It should be noted that if Figure 4 As shown, the automobile washing pump body in this solution has directionality, and in order to avoid the radially extending guide flow channel in the automobile washing 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 retreats, the push cylinder can drive the slider 334 to retract to ensure convenient insertion for the next clamping. The push cylinder and the slider are magnetic and can attract each other to absorb the slider to retract radially when the push cylinder retracts.

[0060] Working principle: When the burrs of the car washing pump body need to be polished, the worker places the car washing pump body on the first conveyor belt with the open mouth facing upward, and ensures that the car washing pump body can enter the guide channel formed by the two baffles. As the width of the guide channel decreases, the car washing pump body driven by the first conveyor belt moves between the two guide plates. During this period, the car washing pump body is guided by the two guide plates to rotate to a state that fits the width between the two guide plates. At this time, the initial positioning of the car washing pump body is completed. Then, the car washing pump body enters the blocking mechanism at the rear. When the car washing pump body enters this mechanism, the car washing pump body is detected by the first proximity switch, and the first proximity switch immediately drives the first telescopic cylinder to extend. After the tongue blocks the car washing pump body, the second telescopic cylinder in the dial mechanism descends and extends into the guide flow channel of the car washing pump body, and then the first telescopic cylinder retracts and resets. Then, the second motor rotates and drives the movable lever to push the radially extending guide flow channel part in the car washing pump body, and the car washing pump body rotates immediately. During the rotation of the car washing pump body, the baffle plate retreats until the car washing pump body rotates into place. Then, the first telescopic cylinder extends again and blocks the car washing pump body, and then the second telescopic cylinder retracts and resets, and the first telescopic cylinder also resets. The car washing pump body that has been turned and guided enters the positioning assembly at the rear through the guide groove. During this process, the vibrator vibrates to increase the success rate of the car washing pump body landing. During this process, if the car washing pump body fails to land, the second proximity switch set in the positioning plate cavity will be able to detect it, and drive the third telescopic cylinder electrically connected to it to extend and pour the car washing pump body in the positioning assembly, so as to avoid the collision between the car washing pump body and the clamping mechanism during subsequent clamping. If the landing is successful, the third motor drives the second conveyor belt to move forward one station. At this time, the positioning assembly with the car washing pump body comes under the clamping mechanism. After the clamping mechanism reaches down and clamps the car washing pump body, the fourth telescopic cylinder in the clamping mechanism retracts and drives the car washing pump body into the grinder. The grinding mechanism in the grinder then performs burr grinding on the car washing pump body clamped by the clamping mechanism. When the grinding is completed, the clamping mechanism takes the car washing pump body out of the main body of the grinder and puts it in the collection area at the rear. The burr grinding operation is completed.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
