Description

[Technical Field]

[0001] This invention relates to the technical field of grinding devices, and in particular to the technical field of self-cleaning cylinder head abrasive fluid grinding devices. [Background Technology]

[0002] As a crucial engine component, the cylinder head serves several essential functions. It acts as a support for the engine's intake and exhaust components and valve train, is mounted with the cylinder block to form a closed combustion chamber, and serves as the mounting base for the engine's timing system at its front end. Existing cylinder heads typically have cast water jackets, water inlet holes, water outlet holes, spark plug holes, bolt holes, and a combustion chamber. These components require grinding before leaving the factory to prevent steel burrs from affecting the cylinder head's proper function.

[0003] Currently, most manufacturers choose to use abrasive fluid polishing devices to remove steel burrs from cylinder heads, such as the highly stable abrasive fluid polishing machine disclosed in utility model patent CN210388777U. However, since the abrasive particles are usually recycled, the steel burrs that are ground off may enter the circulation chamber along with the abrasive particles, and then be drawn up together with the abrasive particles by the jet pump, colliding with the cylinder head and ultimately causing damage to the cylinder head and reducing its quality.

[0004] To address this, utility model patent CN217550060U discloses an engine cylinder head inner cavity treatment device that uses a permanent magnet to attract steel burrs mixed in with the abrasive particles as they pass near an electric conveyor belt, effectively separating the steel burrs from the abrasive particles. However, on the one hand, some smaller steel burrs may be difficult to separate due to electrostatic adsorption, and on the other hand, when the thickness of the abrasive particles mixed with steel burrs on the electric conveyor belt is relatively large, the separated steel burrs may also have difficulty penetrating the abrasive particles and being attracted to the surface of the electric conveyor belt in time. [Summary of the Invention]

[0005] The purpose of this invention is to solve the problems in the prior art and propose a self-cleaning cylinder head abrasive fluid polishing device that has high impurity removal quality, is not easily affected by static electricity, and can effectively avoid damage to the cylinder head from steel burrs.

[0006] To achieve the above objectives, this invention proposes a self-cleaning cylinder head abrasive fluid grinding device, comprising an abrasive vessel, a circulation pipeline, a first solenoid valve, a second solenoid valve, a first injection pump, a distribution pipe assembly, a waste discharge pipeline, a third solenoid valve, a second injection pump, and a controller. The outlet and return outlet of the abrasive vessel are connected by the circulation pipeline, and the first solenoid valve, the distribution pipe assembly, the second solenoid valve, and the first injection pump are sequentially arranged on the circulation pipeline. The distribution pipe assembly is formed by connecting several distribution pipe sections end to end. Each distribution pipe section includes an outer sleeve, an inner sleeve, and an electromagnet ring. The outer sleeve includes an outer sleeve and an inverted conical cylinder. The inverted conical cylinder is coaxially arranged in the cylindrical channel of the outer sleeve, and the edge of its flared end is aligned with the outer sleeve. The inner wall of the sleeve is sealed. The inner sleeve includes an inner sleeve and a positive cone. The inner sleeve is coaxially arranged in the cylindrical channel of the outer sleeve, and its outer wall is fixed to the inner wall of the outer sleeve by several support rods. The tip of the positive cone is set opposite the constricted end of the inverted cone, and its flared end is connected to the inner wall of the inner sleeve. The electromagnet ring is sleeved outside the outer sleeve and is located around the constricted end of the inverted cone and the tip of the positive cone. A third solenoid valve and a second jet pump are respectively installed on the waste discharge pipe, and one end is connected to the distribution pipe section of the distribution pipe group closest to the first jet pump. The controller is electrically connected to the first solenoid valve, the second solenoid valve, the first jet pump, the distribution pipe group, the third solenoid valve, and the second jet pump.

[0007] Preferably, the first solenoid valve, the feed distribution pipe assembly, and the second solenoid valve are arranged sequentially from top to bottom on the same straight line, and the waste discharge pipe is arranged horizontally.

[0008] Preferably, the outer sleeve has a convex ring with several through holes at both ends, and two adjacent material distribution pipe sections are detachably connected by several fasteners that pass through the convex rings.

[0009] Preferably, the inner sleeve further includes an elastic ring installed between the inner sleeve and the positive cone.

[0010] Preferably, the elastic ring is provided with several coaxially arranged annular upper protrusions and annular lower protrusions.

[0011] Preferably, the inner assembly also includes a guide mechanism, by which the conical body is guided to move along the axis.

[0012] Preferably, the guiding mechanism includes a support plate, a movable column, a spring, a sliding sleeve, a support base, and a connecting rod. One end of the movable column is indirectly connected to the positive cone through the support plate, while the other end is fitted with a sliding sleeve. The outer wall of the movable column, located between the support plate and the sliding sleeve, has an annular groove. The spring is fitted outside the movable column and located inside the annular groove. The sliding sleeve is mounted on the support base and indirectly connected to the spring through the connecting rod. The support base is fixed to the inner sleeve through a base plate.

[0013] Preferably, the conical body is hollow, and the support plate is located in the cavity of the conical body.

[0014] The beneficial effects of this invention are:

[0015] 1) By using a combination of abrasive cadmium, circulation pipeline, first solenoid valve, second solenoid valve, first injection pump, distribution pipe assembly, waste discharge pipeline, third solenoid valve and second injection pump, and connecting the distribution pipe section composed of outer sleeve, inner sleeve and electromagnet ring end to end to form a distribution pipe assembly, the abrasive grains mixed with steel burrs can be circulated in and out of the abrasive cadmium along the circulation pipeline. The distribution pipe section makes the abrasive grains mixed with steel burrs continuously shrink and then bounce in all directions under the impact, thereby separating the steel burrs and temporarily storing them on the inner wall of the outer sleeve by magnetic force. When only the third solenoid valve and the second injection pump are turned on, the separated steel burrs can be discharged along the waste discharge pipeline under the action of gravity and suction. The impurity removal quality is high and it is not easily affected by static electricity, which can effectively prevent steel burrs from damaging the cylinder head.

[0016] 2) By setting an elastic ring between the inner sleeve and the positive cone, and adding several coaxially arranged annular upper convex parts and annular lower convex parts above the elastic ring, the elastic ring can support the positive cone and enable the positive cone to bounce vertically when subjected to impact, thereby accelerating the separation speed between the steel burrs and abrasive grains.

[0017] 3) By adding a guide mechanism consisting of a support plate, movable column, spring, sliding sleeve, support seat and connecting rod, the positive cone can be guided to move along the axis. This can not only help support the positive cone and promote its elasticity, but also limit the direction of the positive cone's elasticity to the vertical direction, thereby ensuring the rapid removal of steel burrs and extending the service life of the elastic ring.

[0018] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0023] See Figure 1 , Figure 2 and Figure 3 This invention relates to a self-cleaning cylinder head abrasive fluid grinding device, comprising an abrasive vessel 1, a circulation pipe 2, a first solenoid valve 3, a second solenoid valve 4, a first injection pump 5, a distribution pipe assembly, a waste discharge pipe 7, a third solenoid valve 8, a second injection pump 9, and a controller. The outlet and return port of the abrasive vessel 1 are connected through the circulation pipe 2, and the first solenoid valve 3, the distribution pipe assembly, the second solenoid valve 4, and the first injection pump 5 are sequentially arranged on the circulation pipe 2. The distribution pipe assembly is formed by connecting several distribution pipe segments 6 end to end. Each distribution pipe segment 6 includes an outer sleeve 61, an inner sleeve 62, and an electromagnet ring 63. The outer sleeve 61 includes an outer sleeve 611 and an inverted cone 612. The inverted cone 612 is coaxially arranged in the cylindrical channel of the outer sleeve 611, and the edge of its flared end is sealed to the inner wall of the outer sleeve 611. The inner sleeve 62 includes an inner sleeve 621 and a positive cone 622. The inner sleeve 621 is coaxially disposed in the cylindrical channel of the outer sleeve 611, and its outer wall is fixed to the inner wall of the outer sleeve 611 by several support rods. The tip of the positive cone 622 is positioned opposite the constricted end of the inverted cone 612, and its flared end is connected to the inner wall of the inner sleeve 621. The electromagnet ring 63 is sleeved outside the outer sleeve 611 and is located around the constricted end of the inverted cone 612 and the tip of the positive cone 622. A third solenoid valve 8 and a second jet pump 9 are respectively installed on the waste discharge pipe 7, and one end is connected to the distribution pipe section 6 of the distribution pipe group closest to the first jet pump 5. The controller is electrically connected to the first solenoid valve 3, the second solenoid valve 4, the first jet pump 5, the distribution pipe group, the third solenoid valve 8, and the second jet pump 9.

[0024] The first solenoid valve 3, the feed distribution pipe group, and the second solenoid valve 4 are arranged sequentially from top to bottom on the same straight line, and the waste discharge pipe 7 is arranged horizontally.

[0025] The outer sleeve 611 has a convex ring with several through holes at both ends, and two adjacent material distribution pipe sections 6 are detachably connected by several fasteners that pass through the convex rings.

[0026] The inner sleeve 62 also includes an elastic ring 623, which is installed between the inner sleeve 621 and the positive cone 622.

[0027] The elastic ring 623 is provided with several coaxially arranged annular upper convex parts and annular lower convex parts.

[0028] The inner component 62 also includes a guide mechanism 624, which guides the positive cone 622 to move along the axis.

[0029] The guiding mechanism 624 includes a support plate 6241, a movable column 6242, a spring 6243, a sliding sleeve 6244, a support base 6245, and a connecting rod 6246. One end of the movable column 6242 is indirectly connected to the conical body 622 through the support plate 6241, while the other end is fitted with the sliding sleeve 6244. The outer wall of the movable column 6242, located between the support plate 6241 and the sliding sleeve 6244, has an annular groove. The spring 6243 is fitted outside the movable column 6242 and located inside the annular groove. The sliding sleeve 6244 is mounted on the support base 6245 and is indirectly connected to the spring 6243 through the connecting rod 6246. The support base 6245 is fixed to the inner sleeve 621 through a base plate.

[0030] The conical body 622 is hollow, and the support plate 6241 is located in the cavity of the conical body 622.

[0031] The working process of this invention:

[0032] First, open the door of the abrasive container 1, and then install the cylinder head to be processed into the container cavity of the abrasive container 1 using a clamp. Next, open the first solenoid valve 3, the second solenoid valve 4, the first injection pump 5, and each solenoid coil 63, while simultaneously closing the third solenoid valve 8 and the second injection pump 9. This allows the abrasive to first enter the circulation pipe 2 through the outlet of the abrasive container 1, and then be sent along the circulation pipe 2 to the return port of the abrasive container 1, thus performing circulating grinding. During this period, for the uppermost distribution pipe section 6, abrasive grains mixed with steel burrs can first be input from the top of the outer sleeve 611 and, guided by the inverted cone 612, gradually converge from the periphery to the center as they descend. Subsequently, the abrasive grains mixed with steel burrs first flow out from the constricted end of the inverted cone 612, then impact the tip of the upright cone 622 downwards and are ejected in all directions. At this point, the steel burrs will adhere to the inner wall of the outer sleeve 611 under the magnetic attraction of the surrounding electromagnet ring 63, while the abrasive will fall through the gap between the outer sleeve 611 and the inner sleeve 621 into the next distribution pipe section 6 for a second round of magnetic vibration impurity removal. In addition, when the positive cone 622 is impacted downwards, the support plate 6241 will drive the movable column 6242 to slide downwards along the sliding sleeve 6244 and simultaneously compress the spring 6243. At the same time, when the positive cone 622 is not impacted, the spring 6243 will also provide an upward elastic force to the positive cone 622, thereby causing the positive cone 622 to bounce up and down continuously.

[0033] After working for a period of time, the first solenoid valve 3, the second solenoid valve 4, the first jet pump 5 and each solenoid coil 63 can be closed, while the third solenoid valve 8 and the second jet pump 9 are opened, so that the steel burrs located on the inner wall of each outer sleeve 611 are discharged along the waste discharge pipe 7 under the action of gravity and suction.

[0034] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
