Description

Technical Field

[0001] This utility model specifically relates to the field of machining technology, and more specifically to a die-casting flexible tooling with precise positioning. Background Technology

[0002] Flexible tooling is an important positioning and clamping device in the machining process. It can effectively adjust the clamping quality according to the errors and flatness of the workpiece surface, and ensure the stability of the workpiece during the machining process. Currently, traditional machining fixtures mostly use rigid positioning to clamp workpieces. When clamping, if there is a deviation in the flatness of the workpiece surface, there may be a gap between the clamping fixture and the workpiece surface. This can easily cause positional changes between the workpiece and the fixture during the machining process, and the stability of the workpiece cannot be guaranteed. A search revealed that Chinese patent application CN201620071832.7 discloses a flexible tooling; comprising: a platform with a table, a plurality of positioning angle rulers detachably connected to the table, and a clamping mechanism disposed on the table, wherein the plurality of positioning angle rulers are used to position a workpiece placed on the table, the plurality of clamping mechanisms are used to press the workpiece onto the table, and each positioning angle ruler can be arranged at multiple positions on the table; When clamping the workpiece, the tooling in the aforementioned patent requires manual adjustment of each clamp mounting seat. This results in adjacent mounting seats or mating mounting seats not being able to be on the same cross section or the same plane. Therefore, when using flexible tooling for clamping, the flatness of the workpiece cannot be guaranteed. Furthermore, the flexible tooling in the aforementioned patent cannot achieve a self-locking effect. During processing, when the workpiece vibrates, gaps may form between the flexible tooling and the workpiece, causing the workpiece to shift and making it impossible to guarantee the stability of the workpiece during processing. Utility Model Content

[0003] The purpose of this invention is to provide a die-casting flexible fixture with precise positioning. In this device, the die-cast part is placed on a base, and the bottom of the flexible cylinder positioning block contacts the bottom surface of the die-cast part. The axial pressure on the piston rod is detected by a pressure sensor, and the pressure signal is transmitted to the control system. The control system determines whether the pressure value is less than a preset threshold. If so, it controls the flexible cylinder to lock and keep the piston rod in a fixed position. Then, it controls the drive mechanism to continue driving the flexible positioning mechanism to move until the pressure value is less than the preset threshold, until all flexible cylinders are positioned, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A die-casting flexible tooling with precise positioning, including A base; an adjustment assembly is fixedly installed on the base; an installation plate is fixedly installed inside the adjustment assembly; multiple flexible cylinders on the installation plate are synchronously adjusted so that when the angle of the installation plate is adjusted during processing, the clamping effect of the multiple flexible cylinders on the die-casting part is guaranteed. Flexible positioning mechanism: includes multiple flexible cylinders; the piston rod end of the flexible cylinder is provided with a pressure plate; the flexible cylinder has a built-in pressure sensor; a pad is fixedly installed at the bottom of the end of the pressure plate away from the piston rod. The pad is made of elastic material and the contact surface is wavy. This increases the contact area and ensures the stability of clamping when clamping the die-casting part.

[0005] As a further technical solution of this utility model, the flexible cylinder is fixedly installed on the mounting plate by an L-shaped fixing bracket. The L-shaped fixing bracket is used to fix the flexible cylinder to the mounting plate, ensuring that multiple flexible cylinders move synchronously when the mounting plate moves.

[0006] As a further technical solution of this utility model, a plurality of bases are also fixedly installed on the mounting plate; a die-casting part is placed between the top of the base and the pad.

[0007] As a further technical solution of this utility model, the bottom ends of the mounting plate are fixedly installed with two turntables in the adjustment assembly; one of the turntables is fixedly installed with the driving device.

[0008] As a further technical solution of this utility model, the pressure sensor is fitted with the bottom of the flexible cylinder piston rod, and the pressure sensor is connected to the control system.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, the die-cast part is placed on the base, and the pressure plate is driven by a flexible cylinder to make the pad block contact the surface of the die-cast part. At this time, the pressure value of the pressure plate is detected by a pressure sensor, thereby ensuring that the pad block clamps and fixes the die-cast part. 2. In this utility model, when the pressure value detected by the pressure sensor is less than the preset threshold, the flexible cylinder automatically locks. If it is greater than the preset threshold, the pad at the bottom of the pressure plate needs to be adjusted again until the pressure value is less than the preset threshold. After the multiple flexible cylinders are adjusted, the die-casting is clamped and fixed. 3. In the process of processing, the flexible cylinder is installed on the mounting plate, and the two ends of the mounting plate are fixedly installed with the turntable in the adjustment assembly. The drive device drives one of the turntables to rotate, thereby achieving the overall position adjustment effect of the mounting plate. Attached Figure Description
