Description

Technical Field

[0001] The present invention relates to the technical field of workpiece detection, and specifically provides a detection device for the contour of a workpiece and a workpiece missing-process detection system. Background Art

[0002] In the current bearing industry, the division of labor is becoming more and more clear. The leading enterprises are basically responsible for grinding and assembly, and the rings are basically purchased as precision-turned parts. Among them, the market demand for precision-turned parts of medium and small-sized bearing rings is very large, but the quality requirements for the products supplied to leading enterprises (such as SKF, NSK, FAG, etc.) are very high. At present, the basic turning process routes for rings are numerically controlled turning and hydraulically programmed connected turning. For small batches and complex shapes, numerical control precision turning is usually used. For large-batch products, hydraulic connected automatic turning is usually adopted. The programmed turning is usually multiple machines connected in series, and the processing steps are separated. Each machine independently processes different parts of the ring. During the connection process, there are processes such as material flow and repeated clamping. The missing processing caused by accidental factors such as premature flow of workpieces, missed clamping, and human loading errors is called missing processes. This problem will cause serious problems in the finished product factory. For example, missing the raceway process will cause abnormal impact of the grinding wheel in the finished product factory, missing grooves or chamfers will cause the finished product to be unable to be assembled. Another example is that missing the inspection of the outer contour shape of the workpiece will cause the finished product to be unusable. Summary of the Invention

[0003] The purpose of the present invention is to provide a detection device for the contour of a workpiece and a workpiece missing-process detection system, which can at least solve some defects in the prior art.

[0004] To achieve the above purpose, an embodiment of the present invention provides the following technical solution: A detection device for the contour of a workpiece, including two material channel side plates that are opposite and spaced apart. A passage for the workpiece to pass through is formed between the two material channel side plates. A gate gauge that matches the outer contour shape of the workpiece is provided in the passage.

[0005] Further, the distance between the two material channel side plates is adjustable.

[0006] Further, the distance between the two material channel side plates is adjusted by an adjustment assembly. The adjustment assembly includes two adjustment sliders that are oppositely arranged. The two adjustment sliders are respectively arranged on both sides of the passage, and each adjustment slider abuts against the adjacent material channel side plate. The two adjustment sliders are respectively slidably sleeved on two connecting shafts.

[0007] Further, both of the two connecting shafts are supported by adjustment seats.

[0008] Further, it further includes a material channel bottom plate for placing the two material channel side plates.

[0009] Further, the surface of the material channel bottom plate for placing the two material channel side plates is a passage surface for the workpiece to slide thereon.

[0010] Further, at the end of the passageway, the spacing of the passageway gradually expands.

[0011] Further, the through hole is opened on the upper surface of the curved block, and the fixing member passes through the through hole and presses against the probe head.

[0012] Further, the spacing between the two S-shaped detection strips is adjustable.

[0013] The embodiment of the present invention provides the following technical solution: A workpiece missing process detection system includes an S-shaped bend missing process detection device and the above-mentioned workpiece contour detection device. The S-shaped bend missing process detection device has a detection passage for the workpiece to be detected to pass through, and the passageway is docked with the detection passage.

[0014] Further, along the direction of the steps of each process of the missing process detection, the S-shaped bend missing process detection device is located in front of the workpiece contour detection device.

[0015] Further, along the direction of the steps of each process of the missing process detection, the S-shaped bend missing process detection device is located behind the workpiece contour detection device.

[0016] Compared with the prior art, the beneficial effect of the present invention is that by setting a gate gauge in the passageway, when the workpiece passes through the passageway and encounters the gate gauge, if the outer contour of the workpiece is the same as the shape of the gate gauge with the pre-set contour, then the workpiece can pass smoothly, indicating that this workpiece is a standard part, and if it cannot pass, it means that the outer contour is not machined or machined incorrectly. The overall structure is simple, the cost is low and it is easy to implement, and the effect is good. Description of the Drawings

Specific embodiments

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1:

[0026] Please refer to Figure 1 and Figure 2, an embodiment of the present invention provides an S-shaped bend defective process detection device, including a plurality of first splicing blocks and a plurality of second splicing blocks. Each of the first splicing blocks and each of the second splicing blocks are sequentially spliced to form an S-shaped detection strip 1. There are two S-shaped detection strips 1, and the two S-shaped detection strips 1 are arranged at intervals in the same direction to form a detection channel 17 for the workpiece a to be detected to pass through, and the distance between the two S-shaped detection strips 1 is equal at any position; in each of the S-shaped detection strips 1, the first splicing block is a curved block 10 with a bending arc, and one of the curved blocks 10 has a probe 12 for detecting the inner chamfer of the workpiece a to be detected. In this embodiment, the workpiece a to be detected can be detected by the probes 12 on the curved blocks 10 in the two S-shaped detection strips 1. The S-shaped detection strip 1 is formed by splicing a plurality of splicing blocks, which is easy to quickly assemble and form, improving the detection efficiency. Specifically, there are many ways to splice the first splicing block and the second splicing block, or the first splicing block and the first splicing block, or the second splicing block and the second splicing block. Preferably, it is a detachable splicing, such as magnetic attraction, bonding, snap connection, etc. It can be disassembled after the detection is completed, or it is convenient to replace one of the splicing blocks. Moreover, the independent splicing blocks facilitate batch processing and preparation, and the production cost is low. In addition, for the detection part, in the prior art, as shown in the publication number CN208606695U, a device for detecting the inner chamfer is shown, which uses a detection screw rod with a rounded head for detection. The probe 12 in this embodiment can also use this detection screw rod, but after using the curved block 10 in this embodiment, there is no need to configure a rounded detection head, so that there is no need to design a rounded structure separately, making the overall structure more compact and saving the processing cost of this rounded structure. And during the detection, as Figure 3 shown, when the workpiece a to be detected has a chamfer, there will be a certain gap when it passes through the detection channel 17, and the probe 12 will not block it, and the workpiece a can pass through the detection here smoothly. But as Figure 4 shown, when the chamfer is not processed, there is no such gap at this place, then the probe 12 will block the workpiece a, and the workpiece a will be stuck and stay, and defective products can be detected.

[0027] As an optimized solution of the embodiment of the present invention, please refer to Figure 1 and Figure 2, in one of the S-shaped detection strips 1, the curved block 10 is located at one of the bending parts of the S-shaped detection strip 1. In the other S-shaped detection strip 1, the curved block 10 is located at one of the bending parts of the S-shaped detection strip 1. The two curved blocks 10 are at different bending parts of the S shape. In this embodiment, the S shape has two bending parts, and the two S-shaped detection strips correspond to two S shapes. Each of them is arranged in parallel. Then the two S shapes have four bending parts, corresponding in pairs. The two curved blocks 10 are staggered at the bending parts in two different positions. In this way, as the workpiece a passes through the channel, the chamfers on both sides can be detected.

[0028] As an optimized solution of the embodiment of the present invention, please refer to Figure 1 and Figure 2 , the second splicing block is a square block 11. In each of the S-shaped detection strips 1, there is at least one curved block 10 at the bending part. In this embodiment, the entire S-shaped detection strip 1 can be composed of the square block 11 and the curved block 10. The quantity does not need to be specified and can be spliced at will. As long as it is finally spliced into an S shape and can meet the passing size requirements of the workpiece a and can achieve the detection purpose, it is all right. For example, Figure 1 and Figure 2 In the shown embodiment, in each of the S-shaped detection strips 1, there are three square blocks 11 and two curved blocks 10. The two curved blocks 10 are respectively located at the two bending parts of the S shape. This splicing method is acceptable. At this time, one curved block 10 is spliced between every two square blocks 11. However, there are also cases where two or more square blocks 11 or more curved blocks 10 are continuously spliced. This is all acceptable, and this embodiment does not limit this.

[0029] As an optimized solution of the embodiment of the present invention, please refer to Figure 1 and Figure 2 , a hollow cavity 14 for installing the probe 12 is opened in the curved block 10 provided with the probe 12. The hollow cavity 14 penetrates through the two side surfaces facing the detection channel 17, and the detection end of the probe 12 extends into the detection channel 17 from the hollow cavity 14. In this embodiment, this hollow cavity 14 is provided for installing the probe 12. In the above embodiment, it is refined that the probe 12 can be a screw, and the screw passes through the hollow cavity 14 and extends into the detection channel 17 as a detection piece. Preferably, the hollow cavity 14 is in an I shape.

[0030] For further optimizing the above solution, please refer to Figure 1 and Figure 2, the curved block 10 provided with the probe 12 is further provided with a through hole 19 penetrating through the hollow cavity 14, and a fixing member 13 for fixing the probe 12 is installed in the through hole 19. The through hole 19 is opened on the upper surface of the curved block 10, and the fixing member 13 passes through the through hole 19 and presses against the probe 12. In this embodiment, the probe 12 can be fixed by the fixing member 13. The fixing member 13 can also be a screw, and the through hole 19 can be set as a threaded hole. By screwing in or out the screw to press the probe 12, a fixing effect can be achieved. Of course, other existing fixing methods are also feasible. For example, opening the through hole 19 from other positions, or using other workpiece a to fix the probe 12, are all feasible solutions, and this embodiment does not limit this.

[0031] As an optimized solution of the embodiment of the present invention, please refer to Figure 1 and Figure 2 , the distance between the two S-shaped detection strips 1 is adjustable. In this embodiment, designing the distance between the two S-shaped detection strips 1 to be adjustable can facilitate the detection of workpieces a of various types.

[0032] For further optimizing the above solution, please refer to Figure 1 and Figure 2 , each of the first splicing blocks and each of the second splicing blocks of at least one of the S-shaped detection strips 1 are provided with waist-shaped holes 15. The waist-shaped hole 15 of the first splicing block penetrates through the upper and lower surfaces of the first splicing block, and the waist-shaped hole 15 of the second splicing block penetrates through the upper and lower surfaces of the second splicing block; the extending direction of the straight segment of the waist-shaped hole 15 is consistent with the direction of the distance formed between the two S-shaped detection strips 1; a connecting member 16 for fixing the first splicing block and the second splicing block is provided in the waist-shaped hole 15. In this embodiment, the adjustment method can adopt the form of the waist-shaped hole 15 cooperating with the connecting member 16. The connecting member 16 can be a connecting rod, which can be inserted into the waist-shaped hole 15 and fixed on the placing plate 18 for carrying each of the first splicing blocks and each of the second splicing blocks. The waist-shaped hole 15 can allow the connecting rod to slide therein, and thus the positions of the first splicing block and the second splicing block can be adjusted. Each of the first splicing blocks and each of the second splicing blocks of at least one of the S-shaped detection strips 1 are provided with waist-shaped holes 15. There may be a situation where only the splicing blocks on one of the S-shaped detection strips 1 are provided with waist-shaped holes 15. Then, this S-shaped detection strip 1 can move as a whole, approaching the other S-shaped detection strip 1, the distance decreases, and moving away from the other S-shaped detection strip 1, the distance increases. Of course, it can also be like Figure 1 and Figure 2 shown that the splicing blocks on both S-shaped detection strips 1 are provided with waist-shaped holes 15, so that adjustments can be made according to needs.

[0033] Embodiment 2:

[0034] Please refer to Figure 5 and Figure 6 , an embodiment of the present invention provides a detection device for the contour of workpiece a, including two spaced-apart and facing material channel side plates 20. A passage channel 21 for workpiece a to pass through is formed between the two material channel side plates 20. A gate gauge 22 matching the outer contour shape of workpiece a is provided in the passage channel 21. In this embodiment, it is an embodiment for detecting the external contour of workpiece a, which can be used alone or in combination with the above-mentioned S-shaped detection strip 1 to achieve a complete detection of all aspects of workpiece a. Specifically, by setting the gate gauge 22 in the passage channel 21, when workpiece a passes through the passage channel 21 and encounters the gate gauge 22, if the outer contour of workpiece a is the same as the shape of the gate gauge 22 with a pre-set contour, then workpiece a can pass smoothly, indicating that this workpiece a is a standard part, and if it cannot pass, it means that the external contour is not machined or machined incorrectly. As Figure 6 shown, the external contour of workpiece a is composed of multiple arc segments and multiple straight segments. Correspondingly, the gate gauge 22 is also the same, and their dimensions are consistent, which can ensure that workpiece a can just pass through.

[0035] As an optimized solution of the embodiment of the present invention, please refer to Figure 5 and Figure 6 , the distance between the two material channel side plates 20 is adjustable. Preferably, the distance between the two material channel side plates 20 is adjusted by a distance adjustment component. The distance adjustment component includes two oppositely arranged adjustment sliders 23. The two adjustment sliders 23 are respectively arranged on both sides of the passage channel 21, and each adjustment slider 23 abuts against the adjacent material channel side plate 20. The two adjustment sliders 23 are respectively slidably sleeved on two connecting shafts 24. The two connecting shafts 24 are both supported by adjustment seats 25. In this embodiment, the distance between the material channel side plates 20 is also adjustable to facilitate adapting to various models of workpiece a. When adjusting, the gate gauge 22 should also be adjusted accordingly. The adjustment method can be adjusted by sliding the adjustment sliders 23. The two adjustment sliders 23 are equivalent to clamping the two material channel side plates 20 in the middle. Thus, when adjusting the distance between the two adjustment sliders 23, the distance between the two material channel side plates 20 will also be adjusted. Since workpiece a has dimensions and it will squeeze the material channel side plates 20 when passing between the two material channel side plates 20, only the positions of the two adjustment sliders 23 need to be adjusted. Preferably, multiple such distance adjustment components can be provided and arranged in sequence along the length direction of the material channel side plates 20 to ensure that the positional relationship between the two material channel side plates 20 will not change.

[0036] As an optimized solution of the embodiment of the present invention, please refer to Figure 5 and Figure 6, the device further includes a channel bottom plate 26 for placing the two channel side plates 20. Preferably, when there is the adjustment seat 25, the two channel side plates 20 are fastened to both sides of the channel bottom plate 26.

[0037] As an optimized solution of the embodiment of the present invention, please refer to Figure 5 and Figure 6 , at the end of the passageway 21, the spacing of the passageway 21 gradually expands. In this embodiment, setting the end to a gradually expanding shape can facilitate the workpiece a to automatically break away from the passageway 21 whose previous size was exactly equal to it. This gradually expanding shape can adopt a figure-eight structure, and the figure-eight structure can be a straight line or a curve. This embodiment does not limit this.

[0038] Embodiment Three:

[0039] The embodiment of the present invention provides a workpiece a missing process detection system, including an S-shaped bend missing process detection device and the above-mentioned detection device for the contour of the workpiece a. The S-shaped bend missing process detection device has a detection channel 17 for the workpiece a to be detected to pass through, and the passageway 21 is docked with the detection channel 17. In this embodiment, the above two detection devices can be used together to achieve a comprehensive and complete detection of the workpiece a. Just dock the passageway 21 and the detection channel 17 well to achieve seamless docking. Preferably, the processes of the two can be that the S-shaped bend missing process detection device is in front of the detection device for the contour of the workpiece a, or the S-shaped bend missing process detection device is behind the detection device for the contour of the workpiece a, both are feasible. Or there can be other processes between them, but it is necessary to ensure that several channels are docked and connected.
