Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The present invention will be further described in detail below with reference to the drawings and detailed description for the purpose of enabling those skilled in the art to better understand the aspects of the present invention.
Referring to fig. 1 to 4, fig. 1 is a schematic structural diagram of a semiautomatic valve guide lubrication apparatus according to an embodiment of the present invention; FIG. 2 is a left side view of FIG. 1; FIG. 3 is an isometric view of FIG. 1; fig. 4 is a top view of fig. 1.
The invention provides a semiautomatic valve guide lubricating device, which comprises a mounting base 4 connected with a frame, wherein a plurality of oil spray nozzles 1 for spraying lubricating oil to corresponding valve guides simultaneously and a positioning device for positioning all the oil spray nozzles 1 relative to part or all the valve guides are fixed on the mounting base 4; wherein, any oil nozzle penetration 1 extends to the upper part of the installation base 4 and is communicated with the oil tank through an oil pipe; obviously, in order to realize the semiautomatic control of the device, the device also comprises a control device which is connected with all the oil nozzles 1 and is used for controlling the opening and closing of all the oil nozzles 1 and the oil injection quantity, and the specific setting mode of the control device can refer to the related prior art.
It should be noted that, because the number of valves on the engine cylinder cover, that is, the number of valve guide pipes is large, there are various corresponding forms between the plurality of fuel injection nozzles 1 and the plurality of valve guide pipes, and the following two types of valve guide pipes can be specifically classified: 1. the number of the oil nozzles 1 is smaller than the number of the valve guide pipes; 2. the number of fuel injection nozzles 1 is equal to the number of valve guides. Although the more the number of the oil spray nozzles 1 is, the higher the efficiency of theoretically realizing the lubrication of all the valve guide pipes is, for example, when 24 valve guide pipes are arranged on the engine cylinder cover and the number of the oil spray nozzles 1 is 24, the positioning device enables all the oil spray nozzles 1 to be positioned relative to all the valve guide pipes, and the whole lubrication process can be completed by one-time positioning, but in order to ensure that the relative positions of any one oil spray nozzle 1 and the valve guide pipes are accurately corresponding, the manufacturing precision and difficulty of the device are obviously increased, and the pollution of a cylinder cover is easily caused by inaccurate spraying positions during operation; in addition, since the number of the oil nozzles 1 is excessive, it is difficult to ensure that the oil pressures of the 24 oil nozzles 1 are uniform throughout the spraying process, and the accuracy of adjusting the oil amount is rather lowered.
In summary, the number of the oil spray nozzles 1 is generally smaller than that of the valve guide pipes, and the positioning device enables all the oil spray nozzles 1 to be positioned relative to part of the valve guide pipes, so that all the lubrication processes are completed by positioning in a fractional manner. For example, 4 fuel injectors 1 are fixed to the mounting base 4. In the process of lubricating all valve guide pipes, the position of the mounting base 4 relative to the engine cylinder cover is changed through the frame, and then the positions of the mounting base 4 and the engine cylinder cover are accurately adjusted through the positioning device, so that lubricating oil in the 4 oil nozzles 1 can be accurately sprayed into the 4 valve guide pipes. The 4 oil spray nozzles 1 can spray lubricating oil to 4 valve guide pipes simultaneously, and lubrication of 24 valve guide pipes can be realized after 6 repositioning times.
Compared with the prior art, the semiautomatic valve guide pipe lubricating device provided by the invention has the advantages that the control device controls the oil nozzle 1 to automatically spray lubricating oil to replace the original manual painting, and the number of the oil nozzle 1 can be adjusted according to the total number of the valve guide pipes, so that a plurality of valve guide pipes are lubricated simultaneously, the valve guide pipes do not need to be operated one by one, and the labor capacity is greatly reduced; meanwhile, compared with manual adjustment, the single oil injection quantity is adjusted by the control device, so that higher precision is achieved, and the lubrication degree of all valve guide pipes can be ensured to be consistent.
Besides realizing even quantitative lubrication, the device can directly inject lubricating oil into the valve guide pipe through the oil nozzle 1, compared with sponge smearing, the device can avoid the sponge or particles carried in the air to enter the valve guide pipe to pollute the valve rod, and further cause the friction between the valve rod and the valve to be increased, so that the valve rod is damaged, and even the whole machine is invalid.
The semi-automatic valve guide lubricating apparatus provided by the invention is further described below with reference to the accompanying drawings and embodiments.
Considering that the engine has various models and the cylinder cover structures of the engines with different models are different, the valve guide pipes arranged on the engine are also different, and in order to enable the semiautomatic valve guide pipe lubricating device to be compatible with various models, the mounting base 4 is provided with a plurality of mounting stations for mounting the positioning device; the device further comprises a cylinder cover detection sensor 11 and a plurality of transformation sensors 15, wherein the cylinder cover detection sensor 11 is fixed on the mounting base 4 and used for acquiring the model of the valve guide pipe, and the transformation sensors are in one-to-one correspondence with all mounting stations; wherein the change-over sensor 15 determines the position of the positioning device to determine whether the current position of the positioning device matches the valve guide model determined by the cylinder head detection sensor 11.
The cylinder head detection sensor 11 may employ RFID (Radio Frequency Identification ) technology to achieve the acquisition of the valve guide type, specifically, the cylinder head detection sensor 11 serves as a reader, and when it reads information in a tag attached to the cylinder head surface and transmits it to a control device such as a PLC (Programmable Logic Controller ), the PLC determines the injection amount and controls the injection amount by controlling the injection time of all the injection nozzles 1.
Taking 10L and 12L engines as examples, because the cylinder heads of the two engines have different sizes or structural designs, the positioning means can position the two engines differently, for this purpose, a first mounting station corresponding to the 10L engine and a second mounting station corresponding to the 12L engine can be arranged on the mounting base 4, and a first mold-changing sensor corresponding to the first mounting station and a second mold-changing sensor corresponding to the second mounting station can be arranged on the mounting base 4.
In addition, in the above embodiment, two signal indicators 17 or buzzers corresponding to the first and second change sensors, respectively, may be provided to intuitively acquire the detection result of the change sensor 15.
When the cylinder cover detection sensor 11 detects that the engine at the current working position is a 10L engine, namely the current valve guide pipe is the valve guide pipe corresponding to the 10L engine, the first and second transformation sensors detect the current position of the positioning device, and if the positioning device is positioned at the first installation station, the semiautomatic valve guide pipe lubrication device is in a connection state and can perform oil injection operation; otherwise, when the positioning device is not installed at the first installation station, the semiautomatic valve guide lubricating device always keeps a stop state.
When the cylinder cover detection sensor 11 detects that the engine at the current working position is a 12L engine, namely the current valve guide pipe is the valve guide pipe corresponding to the 12L engine, the first and second type conversion sensors detect the current position of the positioning device, and if the positioning device is positioned at the second installation station, the semiautomatic guide pipe lubrication device is in a connection state and can perform oil injection operation; otherwise, when the positioning device is not installed at the second installation station, the semiautomatic valve guide lubricating device always keeps a stop state.
Obviously, the cylinder head detection sensor 11 is capable of judging whether the cylinder head exists in the current working position, that is, whether the semiautomatic valve guide lubricating device is in the on state or the off state, in addition to detecting the type of the engine cylinder head, and whether the cylinder head exists or not, and whether the positioning device is positioned correctly or not.
Further, a third installation station, a fourth installation station and the like can be further arranged, so that the semiautomatic valve guide lubricating device can be suitable for a third engine and a fourth engine, and particularly can be adjusted according to the production line of an enterprise. In addition, the adjustment of the position of the positioning device between the plurality of installation stations can be realized through manual disassembly and installation, and also can be realized through the control device, and the details are not repeated here.
It should be further noted that, according to a specific arrangement manner of the positioning device, for example, positioning is performed by using two pins on one side, when the positioning device is not located at the first installation station, it is not necessarily located at the second installation station, and there may be an installation error due to human factors, for example, one pin is located in the first installation station, and the other pin is located in the second installation station. In summary, the subsequent injection operation can be performed only when the change-over sensor 15 confirms that the installation station where the positioning device is currently located matches the engine head model.
Preferably, the mounting base 4 has a circular plate structure, and the semiautomatic valve guide lubricating device further comprises an upper cover plate 8 concentrically arranged above the mounting base 4, and a cylindrical shield 14 positioned between the upper cover plate 8 and the mounting base 4; wherein, the up end of guard shield 14 is sealed with upper cover plate 8, and the lower terminal surface of guard shield 14 is sealed with installation base 4. Since the ends of all the fuel injection nozzles 1 are located above the top surface of the mounting base 4 and are connected with the fuel pipes for communicating with the fuel tank, that is, all the fuel injection nozzles 1 are axially penetrated and fixed to the mounting base 4, the ends of the fuel injection nozzles 1 and the fuel pipes connected therewith are located inside the cylinder formed by the upper cover plate 8, the shield 14 and the mounting base 4, and the front end array of the fuel injection nozzles 1 is fixed to the base of the mounting base 4. When the device is operated to lubricate the valve guide, the position of the whole device is adjusted so that the bottom surface of the mounting base 4 is opposite to the outer end surface of the cylinder cover, namely, the front ends of all the oil spray nozzles 1 are opposite to the ports of the valve guide exposed to the outside.
In addition, the control device, the cylinder cover detection sensor 11 and all the transformation sensors 15 can be arranged in the cylinder, so that the pollution in the working environment or the inconvenience in use caused by the complicated and messy overall layout of the device can be avoided.
The oil pipe connected with the tail end of each oil nozzle 1 can be connected with the same oil tank, the oil tank can be arranged in the cylinder, and the oil tank can be used as a part of the semiautomatic valve guide lubricating device provided by the invention or can be independently arranged outside, and an oil pipe port far away from one end of the oil nozzle 1 is connected with the oil tank in use.
Further, a plurality of support columns 7 are further arranged between the upper cover plate 8 and the mounting base 4, the support columns 7 are preferentially arranged in the shield 14, and all the support columns 7 are vertically and uniformly distributed between the upper cover plate 8 and the mounting base 4 by taking the axis of the cylinder as the center so as to increase the connection strength of the upper cover plate 8 and the mounting base 4.
On the basis of any one of the embodiments, the positioning device of the semiautomatic valve guide lubricating device provided by the invention specifically comprises two positioning rods 3 connected to the bottom surface of the mounting base 4, and at least one cylinder cover positioning block 2 fixed on the bottom surface of the mounting base 4 and closely adjacent to any one of the positioning rods 3; the two locating rods 3 are perpendicular to the bottom surface of the installation base 4 and fixed, and meanwhile one end surface of the cylinder cover locating block 2 is parallel to the installation base 4, so that a locating mode of one surface and two pins commonly used for box parts is realized. The dimensions and the relative positions of the two positioning rods 3 and the cylinder cover positioning block 2, and whether the positioning rods 3 are cylindrical or cylindrical, rhombic and other detailed parts can be set according to the cylinder cover model of the engine, and the description is not expanded.
In this embodiment, the engine of 10L and 12L is still taken as an example, and a positioning device of two pins is combined, the number of the installation stations is two, the two installation stations are oppositely arranged with the center of the installation base 4 as the center, any installation station comprises two guide pin holders 5 for detachably connecting the positioning rods 3 and two guide post locking pins 6, specifically, two guide pin holders 5 of the same installation station in the shield 14 are used for detachably connecting the two positioning rods 3 to the bottom surface of the installation base 4, and the guide post locking pins 6 are connected to the guide pin holders 5 and used for locking and unlocking the positioning rods 3. Correspondingly, the number of the mold changing sensors 15 is four, and the four mold changing sensors 15 are in one-to-one correspondence with the four guide pin holders 5 so as to determine the installation station where the two positioning rods 3 are located.
Further, the semi-automatic valve guide lubricating device provided by the invention further comprises two sensor mounting plates 19 which are oppositely arranged by taking the center of the mounting base 4 as the center and are used for respectively fixing all the model changing sensors 15, the shape of the sensor mounting plates 19 is in a sector ring shape, and two ends of the sensor mounting plates 19 are respectively fixed at the middle parts of two adjacent support columns 7. For example, one collar 16 may be fixed to the middle of any one support column 7, and the sensor mounting plate 19 is fixed by being placed in a plane formed by upper end surfaces of the adjacent two collars 16, and by a fastener. It is clear that one sensor mounting plate 19 is able to fix two of the sensors 15, and preferably two of the sensors 15 corresponding to the same mounting station. The sensor mounting plate 19 can reasonably utilize the space of the cylinder, lighten the weight of the cylinder and the internal structure thereof while fixing the mold-changing sensor 15, and facilitate the adjustment of the position of the cylinder through the frame. Likewise, the mounting base 4 can be provided with an oil nozzle mounting seat 18 for fixing all the oil nozzles 1, and the fractional spraying effect of the semiautomatic valve guide lubricating device can be changed by changing the position of the oil nozzle 1 on the oil nozzle mounting seat 18.
Since the number of the oil spray nozzles 1 is smaller than the number of the valve guide pipes, even if all the oil spray nozzles 1 are sprayed with lubricating oil at the same time, the oil spray nozzles 1 need to be divided into several steps to be sequentially implemented, and between two adjacent steps, the position of the positioning device needs to be readjusted, that is, the position of the oil spray nozzle 1 fixed on the mounting base 4 needs to be adjusted to be moved to the right opposite side of the valve guide pipe which is not sprayed, and the quality of the semiautomatic valve guide pipe lubricating device is usually larger, and the semiautomatic valve guide pipe lubricating device is not easy to be manually adjusted by an operator alone. The whole semiautomatic valve guide lubricating device can be connected to the power equipment by using the hanging device, so that the cylinder position, namely the positions of the mounting base 4 and the oil nozzle 1, can be changed by means of the power equipment.
The hanging device specifically comprises a lifting lug 13 for connecting power equipment, such as a crane, and being obliquely fixed relative to the upper cover plate 8, and two handles 9 symmetrically fixed on two sides of the upper cover plate 8 by taking the plane of the lifting lug 13 as a symmetrical plane; wherein, be equipped with a plurality of lifting lug holes 131 on the lug 13, the crane is connected in different lifting lug holes 131 and can adjust the height of whole device. The crane is connected to the lifting lug 13 to move the whole device greatly, and after the moved position is basically determined, one of the handles 9 is manually held to finely adjust the position of the device, so that the positioning device can be accurately positioned on the surface of the cylinder cover.
For convenience of operation, an actuation button 12 for controlling all the fuel injection nozzles 1 may be provided at the tip of any one of the handles 9, and the push button 12 may be mounted by a button mounting post 10 fixed to the tip of the handle. Obviously, the start button 12 is connected with the control device, when the positioning device is accurately positioned on the surface of the cylinder cover, an operator presses the start button 12, all the oil nozzles 1 spray out lubricating oil simultaneously, and all the oil nozzles 1 are closed simultaneously and can be automatically controlled by the control device, so that the lubricating quantity of all the valve guide pipes sprayed in a divided manner is consistent.
