Abstract

This utility model belongs to the technical field of workpiece clamping devices, specifically relating to a pin insertion platform, fixture, and pin insertion system for rapid pressing and accurate concentricity measurement. The pin insertion platform includes: a control module, a fixed base, a sensing component, a clamping component, and an optical calibration component.

[0043] In at least one embodiment, please refer to Figure 3The sensing component 2 includes: a sensor 21; a through hole 15 is provided on the horizontal support 12 within the mounting area 11, the sensor 21 is located below the through hole 15 and is electrically connected to the control module; the control module is configured to obtain the positioning signal of the fixture 5 being mounted into the mounting area 11 through the sensor 21.

[0044] Specifically, sensor 21 may be, but is not limited to, a proximity switch, capable of sensing whether fixture 5 is placed in the mounting area 11.

[0045] In at least one embodiment, please refer to Figure 5 The clamping assembly 3 includes: a plurality of clamping units 31; the mounting area 11 is located on the moving path of each clamping unit 31, and each clamping unit 31 is electrically connected to the control module; the control module is configured to drive each clamping unit 31 to press the fixture 5 against the mounting area 11 after obtaining the positioning signal.

[0046] Specifically, the clamping unit 31 can clamp the fixture 5 in the mounting area 11 to avoid uneven force on the fixture 5, which could lead to tilting or misalignment.

[0047] In at least one embodiment, please refer to Figure 5 The clamping unit 31 includes: a rotary lifting drive 311, a connecting arm 312, and a plurality of pressure columns 313; the connecting arm 312 is movably connected to the rotary lifting drive 311, each of the pressure columns 313 is connected to the connecting arm 312, and the rotary lifting drive 311 is electrically connected to a control module; the control module is configured to drive the rotary lifting drive 311 to rotate or lift the connecting arm 312 and each pressure column 313 to press or release the fixture 5.

[0048] Specifically, the rotary drive consists of a cylinder and a rotary motor, which can rotate and lift the connecting arm 312, thereby driving the pressure column 313 to press or loosen the fixture 5.

[0049] Specifically, the total pressure of the clamping unit 31 is greater than 800N, which enables the fixture 5 to flatten and deform.

[0053] Based on the same technical concept, at least one embodiment also provides a pin insertion system, which includes: a plurality of pin insertion platforms as described above; wherein each of the pin insertion platforms is arranged sequentially.

[0054] In summary, this utility model limits the fixture by setting a clamping area on the fixed base.

The clamping component can also flatten the deformed fixture. An optical calibration component is embedded on the clamping component to achieve high-precision detection of the concentricity of the needle seat and the ejector pin.

[0055] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0056] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0057] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0058] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0059] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
