Description

Technical Field

[0001] This utility model relates to a general-purpose tooling fixture, belonging to the field of tooling fixture technology. Background Technology

[0002] In the production and assembly of precision components, the precision of the fit between various sub-components plays a crucial role. To ensure more stable product performance, some sub-components are often precision-machined using mechanical equipment before product assembly. Currently, the equipment available on the market is mostly geared towards the general public, and the tooling and fixtures provided are relatively limited in specifications, only suitable for processing sub-components of specific sizes. Different fixtures must be customized for sub-components of different sizes. Typically, one machine will handle the processing needs of multiple sub-components. When processing one product is completed and another sub-component needs to be processed, we must change to a new set of fixtures and reposition the components.

[0003] In actual assembly, a suitable fixture is selected based on the workpiece being machined, such as the outer diameter of the valve core. Because the valve core requires high dimensional accuracy for machining, a significant amount of time is spent on adjustment and measurement after each fixture change, greatly impacting production efficiency. There is an urgent need for a universal tooling fixture to reduce the time spent on fixture changes. Utility Model Content

Before processing, only the center position of the mounting hole needs to be positioned and adjusted. That is, after the support is installed, it is also circular, and the position of the mounting window after the workpiece is placed is also centered. Therefore, the base can accommodate various supports, reducing the time spent on adjustment and measurement, and effectively improving production efficiency.

[0032] Example

[0033] This embodiment aims to address the current issue where, during the actual assembly of cylindrical or annular workpieces, a suitable fixture is selected based on the machined outer diameter. Because the workpieces require high dimensional accuracy, each fixture change necessitates significant time for adjustment and measurement, greatly impacting production efficiency. (Refer to...) Figure 1-3As shown, this embodiment provides a universal tooling fixture. By setting mounting holes 11 on the base 1, it can accommodate and install various sizes of support bodies 2 with mounting windows 21. The mounting windows 21 of the support body 2 installed in the mounting holes 11 are circular with the mounting holes 11. Before processing, only the center position of the mounting holes 11 needs to be positioned and adjusted. That is, after the support body 2 is installed, it is also circular, and the position of the mounting window 21 after the workpiece is placed is also the same center. Therefore, the base 1 can accommodate various support bodies 2, reducing the time spent on adjustment and measurement, and effectively improving production efficiency.

[0034] Reference Figure 1-3 As shown, a general-purpose tooling fixture includes: a base 1, a support 2, and a connector 3.

A button is mounted on the surface of the base 1, and the button is electrically connected to the electromagnet 33 and the battery, respectively. For example, the electromagnet 33 can be an existing electromagnetic chuck. An electromagnetic chuck utilizes the principle of electromagnetic induction, generating a magnetic field through an energized coil to attract ferromagnetic workpieces. It mainly consists of a coil, an iron core, and a panel. When the coil is energized, the generated magnetic field firmly attracts the workpiece, and when the power is off, the magnetic force disappears, and the workpiece can be easily removed.

For example, an elastic lever 151 is provided on one side of the inside of the placement groove 15. When the support 2 is inserted into the placement groove 15, the elastic lever 151 can abut against the support 2 to form a limit. There can be multiple placement grooves 15 to accommodate support 2 of different sizes. When the workpiece size measuring component 4 detects the diameter and length of the workpiece, the appropriate support 2 can be taken out from the corresponding placement groove 15 for use.

[0041] Reference Figure 1-3 As shown, the workpiece size measuring component 4 includes a lever 41 disposed on the main body of the workpiece size measuring component 4. The lever 41 can be moved by internal and external forces, thereby driving the workpiece size measuring component 4 to move.

[0042] Reference Figure 1-3 As shown, the measuring groove 14 is provided with an inner groove 143. When a circular workpiece is placed on the inner groove 143, the concave sides of the inner groove 143 can abut against the workpiece. For example, the inner groove 143 is located between two sliding grooves, and the scale 142 is located near the outer edge of the measuring groove 14.
