As a first aspect of the present embodiment, a workpiece placing jig is provided for clamping a workpiece 100 so as to enable the clamped workpiece 100 to maintain a placing state of a specific posture. Referring to fig. 1 in conjunction with fig. 2, the placing jig includes a base 1 for placing the workpiece 100, and a clamping mechanism 2 for fixing the workpiece 100 placed on the base 1. The clamping mechanism 2 comprises a clamp 21, an elastic element 22 and an operating block 3, wherein the clamp 21 is provided with a pair of hinged jaws 211, and each jaw 211 comprises a clamping arm 211a and an operating arm 211b which are respectively positioned at two sides of the hinged part of the jaw 211; the elastic element 22 is connected with at least one of the jaws 211 and maintains a power storage state, so that the pair of jaws 211 can cooperatively clamp the workpiece 100 passing between the clamping arms 211a of the pair of jaws 211 under the action of the elastic element 22; the operation block 3 can move relative to the clamp 21 to operate the operation arm 211b of at least one of the jaws 211, so that at least one of the operation arms 211b rotates towards the other operation arm 211b, and the operation arms 211b rotate towards each other, i.e. the operation arms 211a rotate away from each other, so that the clamp 21 can release the workpiece 100 by operating the operation arms 211b of the jaws 211 by the operation block 3.

By means of the structure, the workpiece placing jig can be clamped and fixed by the clamping mechanism 2 after a workpiece is placed on the base 1, and then the workpiece 100 is placed instead of being held by a worker, so that the worker or detection equipment can conveniently detect or process the workpiece 100. In addition, the workpiece 100 can keep the posture when being placed on the base 1 on the placing jig, so that the workpiece does not need to be repeatedly adjusted in position when being circulated among a plurality of detection or processing stations, labor is saved, and quality inspection efficiency is improved.

Specifically, in this embodiment, the base 1 may be used to place an injector of a diesel engine, the injector is a shaft body having a plurality of stepped shaft sections with different diameters, the base 1 is provided with a notch adapted to the shaft body with any non-maximum diameter of the injector, so that after the operating arm 211b of the operating block 3 operates the clamp 21 to separate the clamping arms 211a of the two clamps 21, the injector can be inserted into the notch and placed on the base 1, and after the operating block 3 is separated from the operating arm 211b of the clamp 21, the clamping arm 211a clamps and fixes the workpiece 100 under the action of the elastic element 22. Of course, in other alternative embodiments, the base 1 may be designed according to the shape of the workpiece 100, for example, a through hole, a groove, or the like may be provided to achieve the purpose of receiving the workpiece 100. The opposing side walls of the two clamp arms 211a may each include a jaw portion recessed inward of the clamp arms 211a, so that the two jaw portions can cooperate to clamp the workpiece 100.

In some alternative embodiments, the clamp 21 may be configured such that the gripping arm 211a and the operating arm 211b of the two jaws 211 are located on the same side of the hinge point of the two jaws 211. That is, the jaws 211 are hinged in a clip-like configuration. Accordingly, in order to keep the clamp 21 in the clamped state without being subjected to an external force, the elastic member 22 may be arranged in different manners as required, for example, a compression spring may be selected as the elastic member 22, and both ends of the compression spring abut against the opposite sides of the operating arms 211b of the two jaws 211; as shown in fig. 2, two compression springs may be selected as the elastic element 22, and the two compression springs respectively abut against the sides of the two claws 211, where the clamping arms 211a are away from each other; for another example, two compression springs may be selected as the elastic member 22, and the two compression springs may be respectively abutted against the sides of the two jaws 211 opposite to the operating arms 211 b; in addition, a tension spring may be selected as the elastic element 22, and two ends of the tension spring are respectively hooked on the opposite sides of the clamping arms 211a of the two jaws 211. In other alternative embodiments, the clamp 21 may further be configured such that the clamping arm 211a and the operating arm 211b of any one of the jaws 211 are respectively located at two sides of a hinge point of the two jaws 211, that is, the two jaws 211 are hinged in a crossed scissors-like structure, and the specific configuration of the elastic element 22 is not described herein again.

Similarly, the structure of the actuating block 3 should be designed according to the different ways of hinging the two jaws 211 of the clamp 21. Taking the example that the clamping arms 211a and the operating arms 211b of the two jaws 211 shown in fig. 2 are located on the same side of the hinge point of the two jaws 211, in order to enable the two operating arms 211b to rotate towards each other after the operation block 3 is operated to achieve the releasing action that the two clamping arms 211a rotate away from each other, the operation block 3 may include a notch portion 31 having a V-shaped cross section and disposed opposite to the operating arms 211b of the pair of jaws 211, and an open end of the notch portion 31 may receive an end of the operating arm 211b of the pair of jaws 211 when the workpiece 100 is clamped. Thus, when the operation block 3 moves in the direction of the clamp 21 and abuts against the end portions of the operation arms 211b of the two jaws 211, and then moves in the direction of the clamp 21, the end portions of the operation arms 211b of the two jaws 211 are pressed by the V-shaped notch portions 31 and rotate inward, so that the holding arms 211a of the two jaws 211 are separated, and the workpiece 100 held by the holding arms 211a of the two jaws 211 is released, or the workpiece 100 to be held can be placed between the holding arms 211a of the two jaws 211. The actuator block 3 may be driven by a drive unit 4 that is driven by a pneumatic, electric, or hydraulic drive operation, for example, to move relative to or away from the clamp 21. For example, the driving unit 4 may include a pneumatic cylinder and a limit switch for limiting the extension length of the output shaft of the pneumatic cylinder, for example, the pneumatic cylinder may be provided with a magnetic switch or the like as a limiting element of the limit position of the reciprocating motion to obtain a suitable extension length of the output shaft.

In a preferred embodiment, the clamping mechanism 2 further comprises a limiting member 23 for limiting the minimum angle between the clamping arms 211a of a pair of said clamps 21. The limiting member 23 may include a limiting post disposed between the two clamping arms 211a of the pair of clamps 21, and the limiting post may be disposed between the two clamping arms 211a and close to the hinge of the two clamping jaws 211, so that when the two clamping arms 211a rotate to a predetermined minimum included angle, the two clamping arms 211a just abut against the limiting post, and thus cannot rotate further. It should be noted that the minimum included angle should be smaller than or equal to the included angle of the two clamping arms 211a when clamping the workpiece 100, so that the elastic element 22 can always be in a power storage state and interfere with the workpiece 100 when clamping the workpiece 100.

As a second aspect of the present embodiment, an apparatus for inspecting a workpiece 100 is provided, which includes the workpiece placing fixture and the inspection device. The inspection apparatus may include a workpiece 100 size inspection unit that inspects the size of the workpiece 100 such as the length, outer diameter, etc., and/or a workpiece 100 surface inspection unit that inspects the workpiece 100 surface roughness, coating insulation, coating aging resistance, etc.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
