Description

Technical Field

[0001] The utility model relates to the technical field of fixture equipment, in particular to a welding and fixing device for an oil pump housing. Background Technique

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. For example, an internal combustion engine usually converts chemical energy into mechanical energy. An engine is applicable to a power generating device and can also refer to the entire machine including the power device. As the available amount of energy such as gasoline is decreasing and users are paying more and more attention to the vehicle use cost, lightweight design requirements are put forward for the weight of the whole vehicle. For example, in order to reduce the manufacturing cost and use cost, lightweight design is adopted for the wall thickness of the product oil pump housing and the connection method of the accessories carried outside the oil pump.

[0003] In the prior art, when welding the oil pump housing, a three-jaw chuck is usually used to fix the oil pump housing. After both parts of the oil pump housing are fixed, the two parts of the oil pump housing are driven to approach each other. The operation is relatively cumbersome and affects the work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to propose a welding and fixing device for an oil pump housing aiming at the problems existing in the background technique.

Detailed implementation mode

[0018] Embodiment 1

[0019] As Figures 1-5 shown, an oil pump housing welding and fixing device proposed in this embodiment includes a frame 1, two mounting discs 2 and two groups of transmission components.

[0020] Two supports 5 are slidably mounted on the frame 1, and a power component for driving the two supports 5 to approach or move away from each other is mounted on the frame 1. The power component includes a servo motor a 61 and a bidirectional lead screw 62. The servo motor a 61 is mounted on the frame 1, the bidirectional lead screw 62 is connected to the output shaft of the servo motor a 61, the bottom ends of the two supports 5 are both connected with connecting sliders 7, the frame 1 is provided with sliding holes 101 for the two connecting sliders 7 to slide, and the two connecting sliders 7 are both threadedly connected to the bidirectional lead screw 62.

[0021] Two mounting disks 2 are respectively mounted on the supports 5 on both sides. A cross hole 201 is formed in the mounting disk 2. Two mutually perpendicular guide rods a8 are mounted inside the cross hole 201. Springs 9 are sleeved on both of the two guide rods a8. Limit plates 20 are slidably mounted at both ends of the two guide rods a8. A connecting rod 21 is connected to a plurality of limit plates 20. A horn cover 3 is arranged on one side of the frame 1 adjacent to the connecting rod 21. A guide rod b22 is connected to the horn cover 3. The guide rod b22 is slidably arranged on the mounting disk 2. A connecting plate 16 is connected to the horn cover 3. A threaded rod 142 is rotatably mounted on the connecting plate 16. A knob 143 is arranged at the end of the threaded rod 142. A threaded sleeve 141 is vertically connected to the rack a10. The threaded sleeve 141 is threadedly connected to the threaded rod 142. When fixing an oil pump housing with a larger diameter, since the outer diameter of the oil pump housing is larger, the moving distance of the limit plate 20 is smaller, resulting in a certain gap between the two parts of the oil pump housing. At this time, the threaded rod 142 can be driven to move upward by turning the knob 143, that is, driving the rack a10 to move upward until the rack a10 is separated from the gear a11. Then, the two parts of the oil pump housing are driven to contact by the arranged power assembly. Subsequently, the horn cover 3 is squeezed by hand until all the limit plates 20 clamp the outer shell of the oil pump housing, and the debugging work is completed.

[0022] Two sets of transmission components are respectively arranged on both upper sides of the frame 1. The transmission component includes a rack a10, a gear a11 and a rack b12. An installation hole 501 is formed in the support 5. The gear a11 is rotatably mounted inside the installation hole 501. The rack a10 is connected to the horn cover 3. The rack b12 is arranged on the frame 1. Both the rack a10 and the rack b12 are meshed with the gear a11.

[0023] A circular ring 4 is connected to the side of the mounting disk 2 away from the horn cover 3. In the initial state, a plurality of limit plates 20 are all located outside the circular ring 4. The circular ring 4 is provided to prevent the oil pump housing from slipping, so that the oil pump housing is in an inclined state before being clamped.

[0024] In this embodiment, during operation, the two parts of the oil pump housing are respectively placed inside the two rings 4 on both sides, so that the oil pump housing is inclined to prevent it from slipping. Subsequently, the provided power assembly is used to drive the two supports 5 to approach each other. During this process, the gear a11 rolls on the rack b12, causing the rack b12 to rotate. The rotation of the rack b12 drives the rack a10 to move, and the movement of the rack a10 drives the horn cover 3 to move. During the movement of the horn cover 3, it squeezes a plurality of connecting rods 21 to move, and the movement of the connecting rods 21 drives the limiting plate 20 to move, causing a plurality of limiting plates 20 to move inward synchronously, so as to clamp the oil pump housing. After clamping, the welded parts of the two oil pump housings come into contact with each other. In summary, in the process of clamping the two parts of the oil pump housing, the present utility model can synchronously drive them to approach each other to achieve the rapid positioning of the oil pump housing, and it is also relatively convenient to release the fixation subsequently.

[0025] Embodiment Two

[0026] As Figure 4 shown, a welding and fixing device for an oil pump housing proposed in this embodiment, compared with Embodiment One, in this embodiment, side plates 17 are connected to both sides of the support 5, limiting columns 18 are fixed on both side plates 17, annular grooves b203 are formed on both sides of the mounting disk 2, and the two limiting columns 18 are respectively arranged in the annular grooves b203 on both sides. The support 5 has a hollow structure, a gear b19 is rotatably installed inside the support 5, a servo motor b15 is installed on the support 5, the output shaft of the servo motor b15 is connected to the gear b19, an annular groove a202 is formed on the circumferential side of the mounting disk 2, and a large gear ring 13 is installed inside the annular groove a202. The large gear ring 13 meshes with the gear b19. Through the setting of the above structure, the driving of the mounting disk 2 can be realized, so as to drive the rotation of the oil pump housing to achieve the welding work on the circumferential side of the oil pump housing.

[0027] The above has described the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model is not limited thereto. Within the scope of knowledge possessed by those skilled in the art to which it pertains, various changes can be made without departing from the purpose of the present utility model.
