Description

Technical Field

[0001] The present invention relates to the technical field of distributing oil pumps, and in particular to a coordinated assembly device and method for distributing oil pumps. Background Art

[0002] The distribution type fuel injection pump has only one distribution plunger, which relies on the rotation of the distribution plunger to distribute the high-pressure diesel to the injectors of each cylinder. The distribution type fuel injection pump has the characteristics of simple structure, few parts, small size, light weight and few failures. Among them, the plunger pair of the distribution type fuel injection pump is the main component of the distribution type fuel pump, which is divided into the plunger and the plunger kit. The coordination between the two needs to be coordinated and checked during assembly.

[0003] Chinese patent CN201620980360.7 discloses a highly reinforced isobaric fuel injection pump, comprising a pump body, a plunger pair and an oil outlet valve assembly assembled in the pump body, a rack adjustment mechanism, a plunger spring, and a flange component. The plunger pair and the oil outlet valve assembly are pressed against the pump body by hexagon socket head screws. The plunger sleeve and the oil outlet valve seat are designed as an integrated whole. The oil outlet valve and the pressure reducing valve are designed as a valve-in-valve type. The lower end of the pump body and the flange component are connected and positioned by a locating pin, and a diesel engine starting air distribution channel is designed on the flange component. This isobaric fuel injection pump has the advantages of a compact structure, high parts fastening and high-pressure sealing performance, a small number of mating surfaces and high-pressure sealing surfaces, a high reliability of the plunger sleeve, and can effectively meet the diesel engine starting requirements, making the diesel engine structure more simplified and compact.

[0004] However, this technical solution and the prior art have the following problems:

[0005] When assembling the existing plunger and plunger kit, it is necessary to ensure the cleanliness between the plunger kit and the plunger. Low cleanliness between the plunger kit and the plunger will cause the plunger to be stuck in the plunger kit, affecting the efficiency of oil injection. At the same time, it is also necessary to detect the sealing between the plunger kit and the plunger to prevent accidental oil leakage. However, most of the existing ones are installed and pulled manually to sense the pressure between the plunger kit and the plunger, which leads to low efficiency of the coordinated assembly between the plunger kit and the plunger and errors in manual judgment. Summary of the Invention

[0032] Another object of the present invention is to address the shortcomings of the prior art and provide a method for collaborative assembly of a distribution oil pump. By combining step one with step five, the air tightness of the plunger pair can be cleaned and verified, thereby improving the assembly effect of the plunger pair.

[0033] To achieve the above object, the present invention provides the following technical solutions:

[0034] A method for cooperatively assembling a distribution type oil pump, comprising:

[0035] Step 1: Transport the plunger sleeve: Lift the plunger sleeve to the bottom of the verification unit through the sleeve transport unit and rotate the plunger sleeve.

[0036] Step 2: Preliminary cleaning: the pretreatment unit is moved downward and falls into the interior of the sleeve cavity of the plunger sleeve. During the rotation of the plunger sleeve, the interior of the sleeve cavity is cleaned;

[0037] Step 3: Collaborative lubrication: The oil block inside the pretreatment unit is moved downward and squeezed by the falling of the trigger ring, so that the oil block contacts the inner wall of the sleeve cavity, so that the inner wall of the sleeve cavity is oiled, sealed and lubricated;

[0038] Step 4: Plunger transport: The plunger transport unit moves to the bottom of the top unit, so that the plunger is moved downward and pushed into the kit cavity;

[0039] Step 5: Joint verification of air tightness: The closed ring plate is clamped onto the surface of the plunger kit so that the air holes on the surface of the plunger kit are sealed and monitored, and then the top unit is used to drive the plunger to move up and down inside the kit cavity so that the air tightness between the plunger and the kit cavity is verified and monitored by the closed ring plate.

[0040] The beneficial effects of the present invention are:

[0041] 1. The present invention uses a telescopic column to drive the coupling to reciprocate up and down within the sleeve cavity. When the airtightness between the plunger and the plunger sleeve is insufficient, the plunger will not be able to move through the sleeve cavity and the air holes and vent grooves on its outer side to drive the trigger plate to move within the air cavity. When the airtightness is satisfied, the air pressure will trigger the folding rod detection unit, thereby achieving coordinated verification of the cleanliness and lubrication of the assembly airtightness.

[0042] 2. The present invention uses a top control unit to drive the trigger ring downward, causing it to fall into the trigger chamber. This squeezes and rotates the right-angle plate, causing the oiling block at its bottom to rotate synchronously outward. The telescopic plate outside the oiling block is squeezed, causing the oiling block to leak out and contact the inner wall of the sleeve chamber. Consequently, the rotation of the rotary drive unit evenly lubricates and seals the inner wall of the sleeve chamber, thereby reducing wear and tear on the plunger and plunger sleeve during assembly verification.

[0043] 3. The present invention uses the downward movement of the telescopic unit to drive the pretreatment unit to move downward and fall into the sleeve cavity inside the plunger sleeve, and to move the closed ring plate outward, so that the air holes of the plunger pair are leaked, and then cooperate with the rotation of the rotary drive unit to drive the plunger pair to rotate inside the clamping part through the roller, thereby facilitating the cleaning brush head on the surface of the pretreatment unit to rotate and clean the sleeve cavity surface of the plunger sleeve. Then, the air extraction unit is started to cooperate with the opened air holes to improve the air extraction efficiency while allowing the cleaned debris to be extracted into the suction cleaning cavity by the cleaning cavity hole, thereby achieving the cleaning of the upper part of the plunger sleeve cavity and the plunger contact part, thereby improving the assembly effect of the injection pump plunger pair;

[0044] 4. The present invention moves the transport sleeve to the position of the opening through the moving parts inside the kit transport unit, so that the motion control unit releases the pneumatic constraint of the pneumatic sleeve, and the plunger kit inside the pneumatic sleeve falls onto the surface of the pushing circular plate through the opening, so that the lifting unit transfers the plunger pair through the bottom opening to between the clamping parts, so that the plunger pair is fixed by the clamping parts, thereby facilitating subsequent combined assembly verification.

[0045] In summary, the present invention has the advantages of good sealing verification and high cleanliness. BRIEF DESCRIPTION OF THE DRAWINGS

[0095] The transport sleeve 207 is moved to the position of the through-port 2011 through the moving part 203 inside the kit transport unit 2, so that the motion control unit 204 releases the pneumatic constraint of the pneumatic sleeve 2061, and the plunger kit inside the pneumatic sleeve 2061 falls onto the surface of the pushing circular plate 2093 through the port 2011, so that the lifting unit 2092 transfers the plunger pair through the bottom port 1012 to between the clamping parts 305, so that the plunger pair is fixed by the clamping parts 305, thereby facilitating subsequent combined assembly verification.

[0096] Through the downward movement of the telescopic unit 3068, the telescopic unit 3068 drives the pretreatment unit 306 to move downward and fall into the kit cavity 304 inside the plunger kit, and moves the closed ring plate 302 outward, so that the air holes of the plunger pair are leaked, and then cooperates with the rotation of the rotary drive unit 209 to drive the plunger pair to rotate inside the clamping member 305 through the roller 3051, thereby facilitating the cleaning brush head 3064 on the surface of the pretreatment unit 306 to rotate and clean the surface of the kit cavity 304 of the plunger kit, and then starts the air extraction unit 308 to cooperate with the opened air holes to improve the air extraction efficiency while allowing the cleaned debris to be extracted into the interior of the suction cleaning cavity 3062 by the cleaning cavity hole 30621, thereby achieving the cleaning of the upper part of the plunger kit cavity 304 and the plunger contact part, thereby improving the assembly effect of the injection pump plunger pair;

[0097] After the cleaning is completed, the top control unit 501 drives the trigger ring 504 to move downward, so that the trigger ring 504 falls into the interior of the trigger chamber 3063, so that the right-angle plate 3066 is squeezed and rotated, and the oiling block 30662 at the bottom thereof rotates synchronously outward, and the telescopic plate 30663 outside the oiling block 30662 is squeezed, so that the oiling block 30662 is leaked and contacts the inner wall of the sleeve chamber 304, and then, under the rotation movement of the rotation drive unit 209, the inner wall of the sleeve chamber 304 is evenly lubricated and sealed with lubricating oil, thereby facilitating the reduction of assembly verification wear of the plunger and the plunger sleeve, wherein the telescopic plate 30663 plays a role in protecting the oiling block 30662, and when the trigger ring 504 is withdrawn from the interior of the trigger chamber 3063, the right-angle plate 3066 will be reset under the gravity of the oiling block 30662 at its bottom, so that the horizontal plate of the right-angle plate 3066 is unfolded inside the trigger chamber 3063;

[0098] After lubrication is completed, the trigger ring 504 and the pre-processing unit 306 are reset, so that the pre-processing unit 306 drives the closed ring plate 302 to be clamped to the outside of the sleeve cavity 304 through the connecting rod unit 303, and then the plunger transport unit 4 is moved, so that the moving part 203 drives the zoom sleeve 403 to move to the bottom of the clamping sleeve 502, and then the clamping sleeve 502 is moved downward so that the top control sleeve 5021 inside the clamping sleeve 502 is contracted and clamped to the top of the plunger, and then the pneumatic constraint of the zoom sleeve 403 is released, so that the top control sleeve 5021 moves the plunger upward and out of the zoom sleeve 403, so that the zoom sleeve 403 is transferred, and then the clamping sleeve 502 drives the plunger to move downward and fall into the interior of the sleeve cavity 304. When the plunger moves downward, the telescopic unit 3068 drives the pre-processing unit 306 to expand outward, thereby reducing the obstruction of the pre-processing unit 306 to the plunger, and then the pre-processing unit 306 is sleeved on the telescopic column 5011. 3024 and the detection unit 3023 are triggered by the air pressure, thereby realizing the coordinated verification of the clean and lubricated assembly air tightness. The plungers and plunger kits that meet the requirements will be dropped to the surface of the kit transport unit 2 together when the clamp 305 releases the constraint, and the plunger kits that do not meet the requirements will be dropped to the surface of the kit transport unit 2 for transportation.

[0100] like Figure 17 As shown, this embodiment provides a method for cooperatively assembling a distribution type oil pump.

[0101] Working steps

[0102] Step 1: Transporting the plunger sleeve: The plunger sleeve is lifted to the bottom of the verification unit 3 by the sleeve transport unit 2, and the plunger sleeve is rotated;

[0103] Step 2: Preliminary cleaning: The pre-treatment unit 306 is moved downward and falls into the interior of the sleeve cavity 304 of the plunger sleeve. During the rotation of the plunger sleeve, the interior of the sleeve cavity 304 is cleaned.

[0104] Step 3: Collaborative lubrication: The trigger ring 504 is dropped to move the oil block 30662 inside the pre-treatment unit 306 downward and squeeze it, so that the oil block 30662 contacts the inner wall of the sleeve cavity 304, so that the inner wall of the sleeve cavity 304 is oiled, sealed and lubricated;

[0105] Step 4: Plunger transport: The plunger transport unit 4 moves to the bottom of the top unit 5, so that the plunger is moved downward and pushed into the sleeve cavity 304;

[0106] Step 5: Joint verification of air tightness: The closed ring plate 302 is clamped onto the surface of the plunger kit so that the air holes on the surface of the plunger kit are sealed and monitored, and then the top unit 5 is used to drive the plunger to move up and down inside the kit cavity 304 so that the air tightness between the plunger and the kit cavity 304 is verified and monitored by the closed ring plate 302.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
