Technical Field

[0001] The utility model relates to the field of die-casting part processing, and more specifically, the utility model relates to a clamping and positioning tooling for automobile die-casting part processing. Background Technique

[0002] Automobile die-casting parts refer to metal parts used in automobiles manufactured by die-casting process. Die-casting is a unique metal casting process, and its principle is similar to injection molding. Under high pressure, liquid or semi-liquid metal is filled into the die-casting mold cavity at a relatively high speed, and the required shape of the parts is obtained through rapid cooling and solidification under pressure.

[0003] When processing automobile die-casting parts, a clamping method is adopted to fix them. At present, most of the fixing equipment uses clamping tooling to fix and process automobile die-casting parts.

[0004] The utility model patent with the publication number CN217833344U discloses a clamping tooling for automobile die-casting part processing. This structure solves the problem that the die-casting parts are prone to shaking during the processing, which affects the processing quality, through a simple mechanical structure.

[0005] However, in actual use, during the processing of automobile die-casting parts, the operator manually operates the mechanical structure, and drives two claws to move closer to each other through a connecting rod to achieve the effect of clamping the automobile die-casting parts. The operation time of the operator for processing each automobile die-casting part is too long, resulting in low production efficiency. Content of the Utility Model

[0006] In order to overcome the above defects of the prior art, the utility model provides a clamping and positioning tooling for automobile die-casting part processing to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A clamping and positioning tooling for automobile die-casting part processing, including a base: Both sides of the base are provided with fuel tanks, and two oil pumps are fixedly connected to the top of each fuel tank. One side of each of the multiple oil pumps is provided with a suction pipe, and one end of the suction pipe is communicated with the fuel tank.

A hydraulic rod is slidably arranged inside the hard pipe. One side of the hard pipe is communicated with a second hydraulic hose. An electromagnetic reversing valve is fixedly connected between the first hydraulic hose and the second hydraulic hose;

[0009] A fixed block is arranged outside the hydraulic rod, and a rotating disk is fixedly connected to one side of the fixed block.

[0010] To achieve the effect of supporting and fixing, preferably, a plurality of hydraulic columns are arranged on the top of the base, an operating table is arranged on the top of the hydraulic columns, a bidirectional screw rod is arranged inside the operating table, support seats are threadedly connected to both sides of the bidirectional screw rod, support rods are arranged on the tops of the two support seats, a fixed shaft is fixedly connected to the tops of the two support rods, and a plurality of fixed rods are arranged on one side of the two fixed shafts.

[0011] To achieve the rotation effect, preferably, a servo motor is fixedly connected to one side of the fixed rod, a rotating shaft is fixedly connected to the output end of the servo motor, and one side of the rotating shaft is fixedly connected to the rotating disk.

[0012] To achieve the effect that the clamping tooling automatically approaches, preferably, a driving motor is arranged on one side of the bidirectional screw rod, and the output end of the driving motor is fixedly connected to one end of the bidirectional screw rod.

[0013] To achieve the effect of collecting and processing waste after the operation is completed, preferably, sweeping ports are opened on both sides of the operating table.

[0014] To achieve the effect of sliding displacement, preferably, sliding grooves are opened inside the plurality of fixed blocks, claws are arranged on one side of the plurality of fixed blocks, moving rods are fixedly connected to the bottoms of the plurality of claws, and the plurality of moving rods are slidably connected to the sliding grooves.

[0015] To achieve the effect of observing lubrication, preferably, pressure observation gauges are arranged outside both of the oil suction pipes, and oil cups are communicated with the outer walls of the plurality of detachable multi-layer spiral pipes.

[0016] The technical effects and advantages of the present utility model:

[0017] 1. By arranging hydraulic components, compared with the prior art, during the processing of automotive die castings, in the face of different automotive die castings, the problem that it is cumbersome for operators to manually operate the mechanical structure to control the clamping and fixing of the automotive die castings by the claws and the production efficiency is low. By operating the main machine to trigger the oil pump, the hydraulic rod slides in the hydraulic pipe to drive the movement of the moving rod, and the movement of the moving rod drives the movement of the claws fixedly connected to the moving rod. By precisely adjusting the pressure through the pressure regulating valve, the pressure applied to the moving rod can be accurately adjusted to achieve the effect of precisely controlling the claws, eliminating the manual operation of adjusting the claws and improving the production efficiency.

[0018] 2. By setting a detachable multi-layer spiral pipe, compared with the prior art, for the disadvantage that it takes time to disassemble and install pipes of different thicknesses, the detachable multi-layer spiral pipe achieves the effect of facilitating the quick disassembly and replacement of various different types of pipes. The rubber ring in the spiral pipe improves the sealing performance, avoiding potential safety hazards caused by improper manual sealing and leakage, and at the same time shortening the production time.
