Description

Technical Field

[0001] This utility model belongs to the field of cylinder head grinding technology, specifically relating to an engine cylinder head grinding paste application device. Background Technology

[0002] As car manufacturers, repairers, and users know, the sealing performance of the intake and exhaust passages of a car engine cylinder head is an important indicator of engine quality and directly affects the engine's power. Before grinding, due to its relatively large surface roughness, it needs to be polished. Polishing is usually done using a grinding machine to polish the surface and holes of the engine cylinder head.

[0003] In the existing technology, for example, Chinese utility model patent with publication number CN215545541U discloses an abrasive paste application mechanism for a gear grinding machine. Specifically, it discloses a base with a support column on the base, a limiting block on the support column, and a mixing tank fixed to the top of the support column. A conveying pipe is opened at the bottom of the outer side of the mixing tank, and the end of the conveying pipe away from the mixing tank is connected to a paste injection head. A sliding ring is slidably connected to the support column, and a first horizontal plate is provided at the end of the sliding ring near the limiting block. An application component is slidably connected to the first horizontal plate. The paste injection head is inserted into the injection hole, which facilitates the delivery of abrasive paste through the injection hole to the output head. Finally, the output head applies the abrasive paste, reducing the manual application steps of the abrasive paste, improving work efficiency, and reducing the burden on workers.

[0004] However, there are several round holes such as exhaust holes and intake holes on the cylinder head. When grinding the inner wall of the round holes, manual coating is still required, which is labor-intensive, inefficient and uneven. Summary of the Invention

[0029] Please see Figures 1 to 6 This application provides an engine cylinder head grinding compound application device, including a working platform 100, a drive assembly 200, and an application assembly 300. The working platform 100 is equipped with a support frame 110. The drive assembly 200 includes a telescopic rod 210 and a rotating rod 220. The rotating rod 220 is rotatably connected to the support frame 110, and the telescopic rod 210 is sleeved on the rotating rod 220 and in a limiting fit. The telescopic rod 210 can extend and retract vertically. The application assembly 300 is equipped with a grinding compound storage cavity 310, a brush plate 320, a transport pipe 330, and a pressing element 340. The grinding compound storage cavity 310 is disposed within the telescopic rod 210. The grinding paste storage cavity 310 is for storing grinding paste. The coating plate 320 is disposed on the outer wall of the telescopic rod 210 away from the rotating rod 220. Several transport pipes 330 are provided, and the outlets of the transport pipes 330 are evenly distributed in the coating plate 320. The inlet of the transport pipe 330 passes through the telescopic rod 210 and is connected to the outlet of the grinding paste storage cavity 310. The pressing member 340 is disposed in the telescopic rod 210 and is connected to the grinding paste storage cavity 310. The end of the pressing member 340 away from the grinding paste storage cavity 310 passes through the rotating rod 220 and extends out of the support frame 110. The pressing member 340 can move up and down in the vertical direction.

[0030] Specifically, the work platform 100 adopts, but is not limited to, a roller-type transport mechanism. Support frames 110, made of steel pipes, plates, etc., are used on opposite sides of the work platform 100. The rotating rod 220 adopts a hollow cylindrical structure and is connected via a first bearing 343. The outer ring of the first bearing 343 connects to the support frame 110, and the inner ring of the first bearing 343 connects to the rotating rod 220. A geared disc 222 is provided at one end of the rotating rod 220 near the support frame 110. A drive motor 111 is installed on the support frame 110. The drive motor 111 meshes with the geared disc 222, activating the drive motor 111 to rotate the rotating rod 220. A telescopic rod 210 is sleeved inside or outside the rotating rod 220 (preferably, the telescopic rod 210 is sleeved inside the rotating rod). Within 220, through a limiting mechanism, the rotating rod 220 drives the telescopic rod 210 to rotate. The telescopic rod 210 extends and retracts along the rotating rod 220 via a cylinder or other means. The inner wall of the telescopic rod 210 is provided with a cylindrical cavity. The polishing paste storage cavity 310 is located inside the cylindrical cavity of the telescopic rod 210, and its length is not greater than the length of the telescopic rod 210. The inlet of the transport pipe 330 is connected to the outlet of the polishing paste storage cavity 310. The outlet of the transport pipe 330 passes through the length of the coating plate 320 and extends from the end of the coating plate 320 away from the rotating rod 220. The pressing member 340 is located at the end of the rotating rod 220. By moving up and down to press the polishing paste storage cavity 310, the polishing paste in the polishing paste storage cavity 310 flows along the transport pipe 330 to the end of the coating plate 320.

[0031] The coating plate 320 has several through holes, the direction of which is consistent with the length of the coating plate 320, and the through holes are arranged at equal intervals in the vertical direction. Each through hole is provided with a transport pipe 330, the inlet of which is connected to the outlet of the grinding paste storage cavity 310, and the end of the coating plate 320 is in contact with the inner wall of the hole on the engine cylinder.

[0032] Further, the engine cylinder head is placed on the work platform 100, and the telescopic rod 210 extends downward into the hole on the engine cylinder head and stops descending. The pressing member 340 is pressed down, so that the polishing paste is transported along the transport tube 330 to the end of the coating plate 320. The drive motor 111 is turned on, so that the rotating rod 220 drives the telescopic rod 210 to rotate, thereby causing the end of the coating plate 320 to rotate along the inner wall of the hole on the engine cylinder head, so that the polishing paste is evenly scraped onto it. After the rotation is completed, the telescopic rod 210 rises and moves the engine cylinder head, so that the telescopic rod 210 is aligned with another hole that needs to be coated.

[0033] The technical solution of this application, which employs an engine cylinder head grinding paste application device, can achieve the following beneficial effects:

[0034] 1. By transporting the polishing paste to the end of the coating plate 320 and rotating the rotating rod 220 to drive the coating plate 320 to rotate, the polishing paste is evenly applied to the inner wall of the engine cylinder head hole, solving the problems of uneven manual application, high labor intensity and inconvenient operation.

[0035] 2. By connecting the pressing element 340 with the polishing paste storage cavity 310, pressing the pressing element 340 causes the polishing paste to flow from the transport tube 330 to the end of the coating plate 320, making the operation simpler and more convenient.

[0036] Based on the above solution, to address the issue of low service life, a rubber scraper 321 is detachably installed at the end of the coating plate 320 away from the telescopic rod 210. The rubber scraper 321 is used to apply polishing paste. The rubber scraper 321 is triangular prism in shape, and one end is fixed to the coating plate 320 by means of snap-fit, bolt connection, etc. The outlet of the transport pipe 330 extends into the rubber scraper 321 and is flush with the inclined surface of the rubber scraper 321. The polishing paste flows out from the outlet of the transport pipe 330 and onto the rubber scraper 321. The coating plate 320 drives the rubber scraper 321 to rotate, thereby achieving the application of polishing paste. Furthermore, the rubber scraper 321 has good elasticity, preventing contact between the coating plate 320 and the engine cylinder head during application, thus reducing service life. The detachable connection of the rubber scraper 321 also makes disassembly and maintenance simpler and more convenient.

[0037] In a preferred embodiment of this application, the pressing member 340 includes a pressing plate 341 and a pressing rod 342. The pressing plate 341 extends into the polishing paste storage cavity 310. One end of the pressing rod 342 is connected to the pressing plate 341, and the other end passes through the rotating rod 220 and extends out of the support frame 110 in a vertical direction, for driving the pressing plate 341 to move up and down in a vertical direction.

[0038] The size of the pressure plate 341 is the same as the cross-sectional size of the polishing paste storage cavity 310, both being circular. The lower end of the pressure plate 341 extends into the polishing paste storage cavity 310. The pressure rod 342 is a round rod, with one end connected to the pressure plate 341 and the other end passing through the support frame 110. The pressure plate 341 and the polishing paste storage cavity 310 are in a limiting fit. When the telescopic rod 210 extends and retracts downward, the pressure plate 341 and the pressure rod 342 move downward along with the telescopic rod 210. The pressure rod 342, which passes through the support frame 110, is pressed manually or mechanically, causing it to move the pressure plate 341 downward, thereby squeezing the polishing paste storage cavity 310 and causing the polishing paste to flow downward along the transport tube 330. The operation is simpler and more convenient, and the same distance is pressed manually or mechanically each time (a scale is set on the pressure rod 342, and the height is the same each time), thus achieving quantitative control and solving the problems of uneven application and difficulty in determining the amount used.

[0039] Furthermore, the pressing component 340 also includes a fixing plate 211, which has a threaded hole. The fixing plate 211 is located above the pressure plate 341 and is fixedly connected to the end of the inner wall of the rotating rod 220. The pressing rod 342 is a threaded rod that passes through the threaded hole and is connected to the pressure plate 341. The fixing plate 211 is fixedly connected to the end of the rotating rod 220, and the threaded hole matches the thread of the pressing rod 342. By rotating the pressing rod 342, the pressing rod 342 drives the pressure plate 341 to rotate simultaneously. Due to the fixing plate 211, the pressing rod 342 moves downward during rotation, thereby driving the pressure plate 341 to move downward and press the polishing paste storage cavity 310. The threaded hole and threaded rod solve the problem that the pressing rod 342 may be moved upward due to misoperation, resulting in the polishing paste not being able to be pressed out on the next press.

[0040] Based on the above solution, the pressure plate 341 and the pressure rod 342 are connected by a bearing 343, with the pressure plate 341 connected to the outer ring of the bearing 343 and the pressure rod 342 connected to the inner ring of the bearing 343. When the pressure rod 342 rotates, the inner ring of the bearing 343 rotates accordingly, while the outer ring of the bearing 343, connected to the pressure plate 341, does not rotate, making operation simpler and more convenient.

[0041] In another preferred embodiment of this application, a threaded sleeve 345 is fitted onto one end of the pressure rod 342 extending from the support frame 110. A retaining plate 344 is provided on the support frame 110, and the retaining plate 344 is in a limiting engagement with the threaded sleeve 345, and the retaining plate 344 can drive the threaded sleeve 345 to rotate. A rack is provided on the periphery of the retaining plate 344, and a rotary motor is provided on the support frame 110, and the rotary motor meshes with the rack.

[0042] The retaining plate 344 is connected to the support frame 110 via the second bearing 343. The inner ring of the second bearing 343 is connected to the support frame 110, and the outer ring of the second bearing 343 is connected to the retaining plate 344. A circular retaining groove is provided in the middle of the retaining plate 344, and a circular retaining block is provided on the outer side of the threaded sleeve 345. The groove and the retaining block are fitted together. The rack of the retaining plate 344 meshes with a rotating motor, which is mounted on the support frame 110. The rotating motor drives the retaining plate 344 to rotate, thereby rotating the threaded sleeve 345 that is engaged with it, realizing the up and down movement of the pressure rod 342. The operation is simpler and more convenient. Furthermore, by setting the rotation time and number of rotations of the rotating motor, the length of the downward movement of the pressure rod 342 can be controlled, making the operation more precise and solving the problem of inconsistent application amounts.

[0043] In the above scheme, a protrusion 212 is provided on the outer wall of one end of the telescopic rod 210, and a groove 221 is provided on the inner wall of the rotating rod 220. The protrusion 212 and the groove 221 are slidably connected.

[0044] The cooperation between the protrusion 212 and the groove 221 solves the problem of the rotating rod 220 driving the telescopic rod 210 to rotate. At the same time, the cooperation between the groove 221 and the protrusion 212 enables the upper and lower limit sliding of the telescopic rod 210. Furthermore, a replenishment tube is provided in the polishing paste storage cavity 310. The other end of the replenishment tube passes through the pressure plate 341 and out of the telescopic rod 210, and is located below the protrusion 212. When the polishing paste is used up, polishing paste is replenished into the polishing paste storage cavity 310 through the replenishment tube, making the operation simpler and more convenient.

[0045] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
