[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0035] like Figures 1 to 4As shown, the utility model is a convenient fixture for detecting a workpiece 1. The workpiece 1 has an annular portion 10 and a bent portion 11. The bent portion 11 is located on one side of the annular portion 10 and close to the periphery of the workpiece 1. The detection fixture comprises: a fixture plate 2, which is provided with a positioning member 3. The positioning member 3 is used to limit the placement position of the workpiece 1 on the fixture plate 2; a plurality of profiling blocks 4 are arranged on the fixture plate 2, and the plurality of profiling blocks 4 are combined to form a detection cavity 40. The bent portion 11 can be placed on the profiling block 4 when the workpiece 1 passes through the positioning member 3, so that the annular portion 10 is located at the opening end of the detection cavity 40; and pressing members 5 are distributed at the periphery of the profiling block 4. The pressing members 5 A clamping block 50 is arranged on it, and the clamping block 50 is movably pressed on the periphery of the workpiece 1 to limit the shaking of the workpiece 1; a plurality of detection parts 6 and digital displays 7, a plurality of detection parts 6 are evenly distributed in the detection cavity 40, and a detection head 60 is movably arranged on the detection part 6, and the top ends of the plurality of detection heads 60 are arranged at the same height, and the bottom of the annular part 10 is movably in contact with the detection head 60; a plurality of digital displays 7 are distributed at the periphery of the tooling plate 2, and each detection part 6 is connected to a digital display 7; when the workpiece 1 to be detected is placed on the profiling block 4, the annular part 10 is movably in contact with the detection head 60, so that the digital display 7 can display the displacement generated by the detection head 60.

[0036] This solution can mainly realize the rapid detection of the annular portion 10 and the bent portion 11 on the workpiece 1. Specifically, Figures 1 to 3 As shown, before the workpiece 1 is inspected, the workpiece 1 is sleeved on the positioning member 3 to achieve the initial positioning of the workpiece 1. When the bending portion 11 on the workpiece 1 is placed on the profiling block 4, the position of the workpiece 1 and the annular portion 10 on the tooling plate 2 is further limited. It is worth noting that the several profiling blocks 4 in this scheme jointly form a detection cavity 40, and the detection member 6 and the detection head 60 are both arranged in the detection cavity 40, so when the bending portion 11 is placed on the profiling block 4, the annular portion 10 is at the open end of the detection cavity 40 and is in active contact with the detection head 60. That is to say, when the workpiece 1 is accurately placed in the detection position, the displacement generated when the several detection heads 60 are pressed against the annular portion 10 can be used and fed back through the digital display 7 connected to the detection member 6. It can be seen that the overall structure of the fixture tooling is relatively simple, the operation is convenient and quick, and after the workpiece 1 is accurately placed, the quality of the workpiece 1 can be quickly fed back through the digital display 7 at the corresponding position, the stability is good, and the qualified rate of the workpiece 1 is effectively guaranteed.

[0037] Furthermore, under the standard workpiece 1, the outer wall of the annular portion 10 is not allowed to be uneven. Therefore, when the workpiece 1 is accurately placed on the profiling block 4, the annular portions 10 at different positions can be detected by the detection heads 60 at various positions. This also enables the detection head 60 to realize feedback of the digital display 7 through the corresponding displacement when detecting the presence of an uneven annular portion 10. That is, after the workpiece 1 is accurately placed, it is possible to judge whether the workpiece 1 meets the customer's usage requirements by observing the value of the digital display 7, thereby greatly improving the detection efficiency and stability during detection.

[0038] Preferably, the digital display 7 in this solution is a digital dial indicator.

[0039] The detection component 6 further includes a mounting platform 61 and a position sensor 62 . The mounting platform 61 is disposed on the tooling plate 2 , and the position sensor 62 is disposed on the mounting platform 61 and connected to the detection head 60 .

[0040] This solution uses a position sensor 62 connected to the installation platform 61, such as Figure 3 As shown, after the detection head 60 detects the annular portion 10 at different positions, the displacement of the detection head 60 can be fed back to the digital display 7 through the position sensor 62. The operation is simple and the inaccuracy during manual detection is effectively avoided. At the same time, the position sensor 62 and the detection head 60 are both located in the detection cavity 40, which greatly saves the space occupied by the entire fixture.

[0041] The positioning member 3 includes: a mounting seat 30, which is arranged on the tooling plate 2, and a base 31 located in the middle of the detection cavity 40 is arranged on the mounting seat 30; a positioning pin 32 and a limit pin 33 are both arranged on the base 31, and a through hole 100 is provided on the annular portion 10, and the through hole 100 is movably sleeved on the positioning pin 32; the limit pin 33 is movably pressed against the bottom wall of the annular portion 10 to limit the distance between the workpiece 1 and the tooling plate 2; a limit block 34 is connected to the positioning pin 32, and the limit block 34 is used to movably press against the inner wall of the through hole 100 to limit the horizontal movement of the workpiece 1.

[0042] like Figure 2 and Figure 4 As shown, before the workpiece 1 is placed, the through hole 100 on the workpiece 1 can be aligned with the positioning pin 32. After the through hole 100 passes through the positioning pin 32, the placement position of the workpiece 1 can be limited by moving the limit pin 33 to ensure that the bent portion 11 on the workpiece 1 can be accurately pressed against the contour block 4, which provides a guarantee for the stability of the workpiece 1 during inspection. In addition, the present solution also provides a limit block 34 at the end of the positioning pin 32 close to the limit pin 33. When the annular portion 10 on the workpiece 1 is sleeved on the positioning pin 32 and pressed against the limit pin 33, the outer wall of the limit block 34 is just clamped in the through hole 100, further limiting the workpiece 1 in the Figure 2 Displacement in the horizontal direction.

[0043] A stepped groove 41 is also formed on the profiling block 4 , and the bent portion 11 movably abuts against the stepped groove 41 , so that the annular portion 10 is placed at the open end of the detection cavity 40 and movably contacts the detection head 60 .

[0044] like Figure 3 As shown, the stepped groove 41 is close to the detection cavity 40, so that when the bent portion 11 on the workpiece 1 is pressed against the stepped groove 41, the annular portion 10 is just at the opening end of the detection cavity 40. Since the top end of the detection head 60 is also at the opening end of the detection cavity 40 in the initial state (i.e. before the workpiece 1 is detected), this design structure effectively ensures that when the workpiece 1 is accurately placed at the detection position, the annular portion 10 can be detected by the detection head 60 at the first time, which greatly improves the detection efficiency and convenience during the detection operation.

[0045] Preferably, continue to refer to Figure 3 The detection member 6 in this scheme also includes a digital display 7 placed horizontally and located on one side of the profiling block 4. A clearance groove 42 is formed on the profiling block 4, and the clearance groove 42 is connected to the step groove 41. The difference is that the digital display 7 at this position is used to detect the bending portion 11. Similarly, before the workpiece 1 is placed, the detection head 60 of the digital display 7 is passed through the clearance groove 42 and extended into the step groove 41. If the bending portion 11 on the workpiece 1 is uneven, a certain displacement can be applied to the detection head 60 on the digital display 7, and then the detection operation of the bending portion 11 on the workpiece 1 is realized under the numerical feedback of the digital display 7.

[0046] The clamping member 5 includes: a fixed seat 51, which is arranged on the tooling plate 2, and a mounting block 52 is arranged on the top of the fixed seat 51; a rotating wrench 53 and a rotating block 54, which are respectively hinged at the two ends of the mounting block 52, and a driving block 55 is arranged on the rotating wrench 53, and the driving block 55 is movably hinged to the rotating block 54; a connecting block 56 is arranged at the end of the rotating block 54 away from the mounting block 52, and the clamping block 50 is detachably connected to the end of the connecting block 56.

[0047] like Figure 3 As shown, when the workpiece 1 is accurately fixed by the positioning pin 32, the limit block 34 and the contour block 4, the worker can turn the rotating block 54 by the driving block 55 while turning the rotating wrench 53, thereby achieving the approach or distance of the clamping block 50 relative to the workpiece 1. Its structure and working principle are the same as those of the clamping device used in the existing tooling, and will not be described in detail here.

[0048] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0049] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0050] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
