Description

Technical Field

[0001] This utility model relates to a tooling for assembling fuel injectors for marine diesel engines, belonging to the field of assembly tooling technology. Background Technology

[0002] The fuel injectors used in modern cars are actually simple solenoid valves. When the solenoid coil is energized, it generates suction, which lifts the needle valve, opens the nozzle, and fuel is sprayed out at high speed through the annular gap between the needle valve head and the nozzle, forming a mist that facilitates complete combustion. In the past, diesel engine fuel injectors were mechanically controlled. Mechanical diesel injectors work by controlling precision components (needle valve and needle valve body). The injector component is one of the three major precision components of traditional diesel engines. The three major precision components are: plunger and plunger sleeve, needle valve and needle valve body, and delivery valve and delivery valve seat. Gasoline engine injectors are part of the gasoline engine electronic control system, replacing the carburetor in carburetor-type gasoline engines. The main types of injectors used in automobiles are diesel injectors, gasoline injectors, and natural gas injectors. Some foreign manufacturers can now manufacture hydrogen-specific injectors.

[0003] Chinese Patent Publication No. (CN 212977329 U) discloses an automatic assembly device for automotive fuel injectors, including a moving wheel, a control panel, a hydraulic cylinder, a ring assembly, a hydraulic rod, a return spring, a motor, and a shock-absorbing spring. The moving wheel is located at the bottom of the entire device, and a base is connected to the upper end of the moving wheel. The shock-absorbing spring is provided inside the base. The ring assembly is connected to the bottom of the main body, and the hydraulic rod is provided inside the ring assembly. Both ends of the hydraulic rod are provided with a first connecting rod and a second connecting rod. The return spring is connected between the second connecting rod and the hydraulic rod. This utility model is an automatic assembly device for automotive fuel injectors. This device adopts semi-automatic control, which solves the problems of high manpower and material resources, high production costs, and extremely low production efficiency of manual assembly operations. This device uses a motor to drive a turntable to rotate, and the fuel injector is manually placed into a limiting sleeve. The ring assembly automatically assembles the sealing ring onto the fuel injector.

[0004] The above-mentioned device mainly relies on the limiting sleeve to fix the fuel injector. However, due to different types of diesel engines, the size of the fuel injector is also different. When the size of the fuel injector changes, it may be impossible to fix the fuel injector firmly. If the fuel injector is pressed down for assembly, it may cause the fuel injector to tilt, making it impossible to assemble its parts properly and making it inconvenient for operators to use.

[0005] To address this, a tooling for assembling marine diesel engine injectors is proposed. Summary of the Invention

[0006] In view of this, the present invention provides a tooling for assembling marine diesel engine injectors to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0007] The technical solution of this utility model is implemented as follows: a marine diesel engine injector assembly fixture, comprising: an assembly component, the assembly component including a base plate, a servo press machine fixedly installed on the top of the base plate, and a housing fixedly installed on the top of the base plate;

[0008] The fixing assembly includes a bidirectional motor, which is fixedly installed on the rear side of the bottom of the inner cavity of the housing. Connecting rods are fixedly connected to the output ends of both sides of the bidirectional motor. Driven bevel gears are movably connected to both sides of the inner cavity of the housing.

Vertical rods are fixedly installed on the tops of the two moving plates. Clamping plates are fixedly installed on the tops of the two vertical rods.

[0009] More preferably, each of the two connecting rods is fixedly mounted with a driving bevel gear on its left and right sides, and a transmission rod is fixedly mounted on the surface of each of the two driven bevel gears, with the surface of each transmission rod meshing with the surface of each of the two driven bevel gears.

[0010] More preferably, protective pads are fixedly installed on the inner sides of both clamping plates, and the protective pads are made of rubber.

[0011] More preferably, the top of the box body is provided with a sliding groove, and both vertical rods pass through the inner cavity of the two sliding grooves and extend to the top of the box body.

[0012] More preferably, guide rods are fixedly installed in the inner cavity of the box, and the four moving blocks are slidably connected to the left and right sides of the surfaces of the two guide rods.

[0013] More preferably, a movable groove is provided at the bottom of the inner cavity of the box, and the bottoms of the two movable plates are slidably connected to the inner cavity of the movable groove.

[0015] More preferably, the left and right sides of the housing are threaded with mounting bolts, and the bottoms of the four mounting bolts are threaded to the inner surface of the base plate.

[0016] The present invention has the following advantages due to the adoption of the above technical solution:

[0017] I. This utility model, by setting a fixing component and through the output of a bidirectional motor, enables the driven bevel gear to drive the moving plate to move inward. By adjusting the position of the clamping plate, it is convenient to clamp and fix fuel injectors of different sizes, which improves the flexibility of equipment use and avoids the situation where the size of the inner side of the clamping plate does not match the size of the fuel injector, causing the fuel injector to shift or tilt due to the pressing of the servo press machine. This ensures the stability of the fuel injector assembly and makes it convenient for operators to use.

[0018] II. This utility model, by setting a protective pad, can prevent scratches on the surface of the fuel injector when the clamping plate holds the fuel injector. By setting a sliding groove, the movement of the vertical rod can be limited to prevent the vertical rod from shifting during movement, thus affecting the fixing of the fuel injector.

[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0030] like Figure 1-5 As shown, this utility model embodiment provides a marine diesel engine injector assembly tooling, including: an assembly component 1, the assembly component 1 including a base plate 101, a servo press machine 102 fixedly installed on the top of the base plate 101, and a housing 103 fixedly installed on the top of the base plate 101.

[0031] Fixing component 2 includes a bidirectional motor 201, which is fixedly installed on the rear side of the bottom of the inner cavity of housing 103. Connecting rods 202 are fixedly connected to the output ends on both the left and right sides of the bidirectional motor 201. Driven bevel gears 204 are movably connected to both the left and right sides of the inner cavity of housing 103. Mounting blocks 206 are fixedly installed on the front and rear sides of the surfaces of the two driven bevel gears 204. Connecting rods 207 are movably connected to the surfaces of the four mounting blocks 206. The other ends of the four connecting rods 207... Each of the four movable blocks 208 is movably connected. Movable plates 209 are fixedly installed on the inner side of each of the four movable blocks 208. Vertical rods 210 are fixedly installed on the top of each of the two movable plates 209. Clamping plates 211 are fixedly installed on the top of each of the two vertical rods 210. Active bevel gears 203 are fixedly installed on the left and right sides of each of the two connecting rods 202. Transmission rods 205 are fixedly installed on the surface of each of the two driven bevel gears 204. The surfaces of the two transmission rods 205 mesh with the surfaces of the two driven bevel gears 204.

[0032] By setting the fixed component 2, the output of the bidirectional motor 201 causes the driven bevel gear 204 to drive the moving plate 209 to move inward. By adjusting the position of the clamping plate 211, it is convenient to clamp and fix oil injectors of different sizes, which improves the flexibility of equipment use and avoids the situation where the size of the inner side of the clamping plate 211 does not match the size of the oil injector, causing the oil injector to shift or tilt due to the pressing of the servo press machine 102. This ensures the stability of oil injector assembly and makes it convenient for operators to use. Example 2

[0033] like Figure 1-6 As shown, in one embodiment, protective pads 212 are fixedly installed on the inner sides of the surfaces of the two clamping plates 211. The protective pads 212 are made of rubber. A sliding groove 213 is provided on the top of the box body 103. Two vertical rods 210 pass through the inner cavities of the two sliding grooves 213 and extend to the top of the box body 103. Guide rods 214 are fixedly installed in the inner cavity of the box body 103. Four moving blocks 208 are slidably connected to the left and right sides of the surfaces of the two guide rods 214. A moving groove 215 is provided at the bottom of the inner cavity of the box body 103. The bottoms of the two moving plates 209 are slidably connected to the inner cavity of the moving groove 215. Support blocks 216 are movably connected to the surfaces of the two connecting rods 202 through bearings. The bottoms of the two support blocks 216 are fixedly installed at the bottom of the inner cavity of the box body 103. Mounting bolts 104 are threadedly connected to the left and right sides of the box body 103. The bottoms of the four mounting bolts 104 are threadedly connected to the inner surface of the base plate 101.

[0034] By setting the protective pad 212, scratches on the surface of the fuel injector can be avoided when the clamping plate 211 clamps the fuel injector. By setting the sliding groove 213, the movement of the vertical rod 210 can be limited to prevent the vertical rod 210 from shifting during movement, thus affecting the fixing of the fuel injector. By setting the guide rod 214, the movement of the moving block 208 can be limited to prevent the moving block 208 from shifting during movement, thus affecting the clamping of the fuel injector. By setting the moving groove 215, the movement of the moving plate 209 can be limited to prevent the moving plate 209 from shifting during movement, thus affecting the fixing stability of the fuel injector. By setting the support block 216, the connecting rod 202 can be supported to prevent the connecting rod 202 from falling off after long-term use. By setting the mounting bolt 104, the disassembly and assembly of the housing 103 can be facilitated, making it easy to maintain and repair the components inside the housing 103.

[0035] In operation, the present invention works as follows: the fuel injector is placed inside the clamping plate 211, and then the output of the bidirectional motor 201 drives the connecting rod 202 to rotate the active bevel gear 203. At this time, the active bevel gear 203 cooperates with the transmission rod 205, and the driven bevel gear 204 rotates synchronously. As the driven bevel gear 204 rotates, the mounting block 206 rotates. The mounting block 206 cooperates with the connecting rod 207, so that the moving block 208 drives the moving plate 209 to move inward. At this time, the moving plate 209 drives the vertical rod 210 and the clamping plate 211 to move inward. The clamping plate 211 clamps and fixes the fuel injector, thereby completing the fixing of the fuel injector. Then, the sealing ring or the parts to be pressed are placed in the inner cavity of the fuel injector, and the servo press machine 102 presses them down to assemble them, thus completing the assembly of the fuel injector.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
