Description

Technical Field

[0001] This utility model belongs to the field of mold processing technology, and more specifically, it relates to a high-precision automotive mold clamping fixture. Background Technology

[0002] Automobiles are assembled from various parts. Automobile molds are needed when processing automobile parts. High-precision automobile molds require clamping fixtures for positioning during processing. The automobile molds are positioned on the clamping fixtures to ensure that the position of the automobile molds is fixed. The processing equipment then performs processing operations such as welding and grinding on the automobile molds.

[0003] According to CN202022001629.1, this utility model discloses a clamping fixture for automobile mold production, relating to the field of automobile mold technology. It addresses the problem that existing automobile mold production fixtures are inconvenient to adjust due to their overly compact structure. The fixture body has four movable grooves inside, each groove housing a connecting slider. Each connecting slider houses two rollers. A clamping plate is located at the upper end of the connecting slider, and a push-pull adjustment rod is located at one end of the connecting slider. The four movable grooves are symmetrically distributed about the center point of the fixture body. Each connecting slider has two internal slots integrally formed with the connecting slider. Each roller has a rotating shaft at both ends, integrally formed with the roller.

[0004] Based on the above, existing clamping fixtures generally fix the mold through a clamping structure. The clamp only holds the outside of the mold. When the processing equipment performs processing operations on the automotive mold, it will generate vibration. The vibration will cause the automotive mold to move slightly. The slight displacement will affect the processing error, affect the mold processing accuracy and the quality of the finished product, and ultimately affect the use effect of high-precision automotive molds. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a high-precision automotive mold clamping fixture. This solves the problem that existing clamping fixtures typically fix the mold using a clamping structure, with the clamp only holding the outer side of the mold. When the processing equipment operates on the automotive mold, vibrations occur, causing slight displacement of the mold. This slight displacement affects processing errors, impacting mold processing accuracy and finished product quality, ultimately affecting the performance of the high-precision automotive mold.

[0006] The purpose and function of this high-precision automotive mold clamping fixture are achieved by the following specific technical means: A high-precision automotive mold clamping fixture includes a fixture body, a fixture motor, limiting pressure blocks, extrusion sliders, stabilizing pressure blocks, a limiting extrusion mechanism, and an extrusion lifting mechanism. The fixture motor is fixedly connected to the lower side of the middle position inside the fixture body. Four sets of limiting pressure blocks are provided, each slidably connected to the upper surface of the fixture body, with their upper sides sliding on the upper surface of the fixture body. Four sets of extrusion sliders are also provided, each slidably connected to the upper surface of the fixture body. Four sets of stabilizing pressure blocks are also provided, each slidably connected to the upper surface of the fixture body. The limiting extrusion mechanism is located inside the fixture body. Four sets of extrusion lifting mechanisms are also provided, each located inside one of the four sets of limiting pressure blocks.

[0007] Furthermore, the limiting compression mechanism includes: a motor bevel gear, a limiting rotating shaft, and a limiting bevel gear; the motor bevel gear is coaxially and fixedly connected to the rotating shaft of the tooling motor, and the motor bevel gear is rotatably connected to the middle position inside the tooling body; a total of four sets of limiting rotating shafts are provided, and the four sets of limiting rotating shafts are rotatably connected to the four sides inside the tooling body; a total of four sets of limiting bevel gears are provided, and the four sets of limiting bevel gears are coaxially and fixedly connected to the inner side of the four sets of limiting rotating shafts, and the four sets of limiting bevel gears mesh with the motor bevel gear to form a bevel gear transmission mechanism.

[0008] Furthermore, the limiting extrusion mechanism also includes: limiting screws and limiting screw holes; there are four sets of limiting screws, which are coaxially fixedly connected to four sets of limiting rotating shafts, and the four sets of limiting screws are rotatably connected to the four sides inside the tooling body; there are four sets of limiting screw holes, which are respectively opened on the lower side of the four sets of limiting pressure blocks, and the four sets of limiting screws are respectively threadedly connected to the four sets of limiting screw holes.

[0009] Furthermore, the limiting extrusion mechanism also includes: extrusion racks, extrusion shafts, and extrusion gears; there are four sets of extrusion racks, which are fixedly connected to the outside of the limiting pressure block and slidably connected to the four sides inside the tooling body; there are four sets of extrusion shafts, which are rotatably connected to the inside of the tooling body; there are four sets of extrusion gears, which are coaxially fixedly connected to the lower side of the four extrusion shafts, and the four sets of extrusion gears mesh with the four sets of extrusion racks to form a gear and rack transmission mechanism.

[0010] Furthermore, the limiting extrusion mechanism also includes: extrusion screws and extrusion screw holes; there are four sets of extrusion screws, which are coaxially fixedly connected to the upper end faces of four extrusion rotating shafts, and the four sets of extrusion screws are rotatably connected to the inner side of the tooling body; there are four sets of extrusion screw holes, which are respectively opened on the lower side of the inner side of the four sets of extrusion sliders, and the four sets of extrusion screws are threadedly connected to the four sets of extrusion screw holes.

[0011] Furthermore, the extrusion lifting mechanism includes a lifting lever; the lifting lever is rotatably connected to the lower side of the outer end face of the limiting pressure block, and the outer end face of the lifting lever is provided with a hexagonal groove structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention employs a limiting extrusion mechanism, allowing the operator to place the mold on the upper surface of the tooling body. The tooling motor drives the limiting pressure block to slide, clamping the mold and fixing its position. A stabilizing pressure block on the upper side of the limiting pressure block is located at the edge of the upper surface of the mold. Simultaneously, the sliding of the limiting pressure block drives the upper side of the extrusion slider to slide, lifting the mold and locking it under the stabilizing pressure block. This ensures that the mold's position is completely fixed, preventing slight displacement due to vibration during processing and guaranteeing the processing quality of the mold.

[0014] This utility model adopts a pressing and lifting mechanism, which allows the operator to twist the lifting lever to rotate and drive the stabilizing block to slide. When the stabilizing block slides, the height of the stabilizing block limit is adjusted to ensure that the stabilizing block can hold molds of different heights, thereby increasing the application range of the stabilizing block and making it convenient for the operator to use clamping fixtures.
