Description

Technical Field

[0001] The utility model relates to the technical field of oil pump body processing, in particular to a multi-station automatic clamping oil pump body milling and drilling device. Background Art

[0002] The oil pump body houses and supports various moving parts inside the oil pump, such as gears, plungers, blades, etc., and provides a closed working space for the oil, ensuring that the oil can flow along the predetermined path in the pump body to achieve the functions of oil suction and pressure. In the field of mechanical manufacturing, the oil pump body is a key component of the oil pump. Its processing accuracy and efficiency have a vital impact on the performance and production cycle of the entire oil pump.

[0003] Currently, during the surface machining phase of oil pump bodies, a single-piece manual clamping method is used on a CNC lathe. However, it is difficult for manual operation to accurately control the clamping force at each time, which can easily lead to uneven force and frequent small displacements of the workpiece during the turning process, seriously affecting the accuracy and quality of surface machining. In the drilling and sealing groove milling process of the oil pump body, although multiple pieces are processed on a vertical machining center, manual clamping is still relied upon. The workpieces need to be placed and clamped one by one, making the operation process more complicated and reducing machining efficiency. In addition, for oil pump bodies of different specifications, special tooling is required. This not only leads to a large number of tooling, increasing the cost and difficulty of tooling design, manufacturing, storage and management, but also further prolongs the overall processing cycle due to tooling switching and debugging. In addition, manual clamping makes it difficult to achieve fast and accurate positioning during drilling and sealing groove milling operations, which can easily lead to position deviations, resulting in a decrease in product qualification rate and an increase in scrap rate, seriously affecting the machining efficiency and quality of the oil pump body. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-station automatic clamping oil pump body milling surface drilling device to solve the above-mentioned technical deficiencies.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-station automatic clamping oil pump body milling and drilling device, comprising a base plate, the upper end of the base plate is connected to three vertical plates in sequence, the upper end surfaces of the three vertical plates are symmetrically connected to two upper plates, and the two upper plates are respectively provided with a pneumatic automatic clamping assembly, the pneumatic automatic clamping assembly includes a cylinder mounted on the lower end surface of the upper plate by screws, the output end of the cylinder is connected to a pull rod, the upper end surface of the pull rod passes through and extends to the upper end of the upper plate, the upper end surface of the upper plate is fixedly connected with a locating pin, the locating pin is located on one side of the pull rod, and multiple parts can be clamped at one time, and pneumatic automatic clamping is adopted. Compared with traditional processing methods, it can greatly improve the dimensional accuracy of the milling surface drilling and reaming of the oil pump body, and the high-precision positioning and stable clamping effectively reduce the generation of waste caused by processing errors, ensure the accuracy of processing dimensions, and improve the qualified rate of products.

[0006] Preferably, the outer wall of the pull rod is provided with a waist-shaped groove, and a latch is inserted into the waist-shaped groove.

[0007] Preferably, the entirety of the latch is divided into a first part, a second part and a third part, the first part and the third part are cylindrical structures, and the outer side wall of the second part is flat.

[0008] Specifically, the waist-shaped groove of the pull rod cooperates with the flat part of the pin to prevent the rotation of the cylinder piston, thereby realizing the milling and drilling processing of the oil pump body by the vertical machining center. It can avoid the displacement of the pump body due to vibration or cutting force during the machining process, prevent machining deviation, ensure the stability of machining accuracy, and thus ensure that the vertical machining center can smoothly carry out the milling and drilling processing of the pump body.

[0009] Preferably, a screw is threadedly connected to the groove on the upper end surface of the upper plate, and a screw groove adapted to the screw is opened on the upper end surface of the vertical plate. By screwing the screw, its connecting end is screwed into the screw groove, thereby realizing the connection between the upper plate and the vertical plate. A plurality of mounting bolts are threadedly connected to the surface of the vertical plate, and by screwing the mounting bolts, the vertical plate can be vertically fixed to the base plate.

[0010] Through the above technical solution:

[0011] During processing, the oil pump body that has been processed previously is first completely positioned on the upper plate through two pins on one side, and then the pin is passed through the threaded bottom hole of the oil pump body, the waist groove of the pull rod and the hole of the oil pump body. Under the action of the cylinder pulling the pull rod, the oil pump body is positioned and clamped, which effectively limits the translation and rotational freedom of the pump body in the plane, ensuring that the position of the pump body is almost completely consistent during each processing, thereby ensuring the flatness of the milling plane and the positioning accuracy of the drilling hole.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] 1. By setting up the cylinder, pull rod, latch and positioning pin, during processing, the oil pump body can be completely and accurately positioned on the upper plate using two pins on one side, effectively limiting the translation and rotational freedom of the pump body in the plane, ensuring that the position of the pump body is almost completely consistent during each processing, thereby ensuring the flatness of the milling plane and the position accuracy of the drilling. The latch passes through the threaded bottom hole of the pump body, the waist groove of the pull rod and the hole of the pump body, and then the cylinder is used to pull the pull rod to achieve positioning and clamping. At the same time, the waist groove of the pull rod cooperates with the flat part of the latch to prevent the cylinder piston from rotating, providing a stable and uniform clamping force, which can avoid displacement of the pump body due to vibration or cutting force during processing, prevent processing deviation, and ensure the stability of processing accuracy, thereby ensuring that the vertical machining center can smoothly carry out milling and drilling processing of the pump body, greatly improving processing quality and efficiency.

Compared with traditional processing methods, it can greatly improve the dimensional accuracy of the milling surface and drilling and reaming of the oil pump body. The high-precision positioning and stable clamping effectively reduce the generation of scrap due to processing errors, ensure the accuracy of processing dimensions, and improve the product qualification rate. In addition, workpieces of different specifications do not need to be frequently replaced with tooling, which reduces the frequency of tooling replacement, avoids production stagnation caused by tooling replacement, and thus improves production efficiency.
