Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved by the present application more clear, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

It will be understood that when an element is referred to as being "mounted" or "disposed" on another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

It is to be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present application and simplify description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be configured and operated in a particular orientation, and therefore should not be construed as limiting the present application.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Sensor technology, communication technology and computer technology are three major posts of modern information technology, and sensors are products of science and engineering, and depend on new phenomena and new rules of science, and also depend on new technologies and new processes. Along with the development of science and technology and the progress of times, the sensor is updated and replaced quickly, the demand is large, and the demand growth speed is high, so that the microminiature sensor component has a good market prospect.

The precision requirement on microminiature sensor parts is extremely high in the current market, and the processing scratch or other damage has serious influence on the later operation, so that the peripheral surface of the microminiature sensor parts is required to be detected after the processing is finished. As shown in fig. 1, the round minute workpiece 100 needs to be inspected at its outer periphery in the production process. Specifically, it is necessary to rotate the workpiece 100 at the time of inspection, and observe the outer periphery thereof with an electron microscope to confirm whether or not there is a flaw.

Because the small size of the round minute workpiece 100 and the inability to achieve internal clamping, only hand-held rotation is used for inspection under a microscope, resulting in increased operator fatigue. When the method is adopted for detection, because parts are tiny, frequent focusing operation under a microscope is needed, and the operation difficulty and complexity are increased; moreover, it is difficult to rotate the work 100, and fatigue of the operator is further increased, so that the spirit is easy to be not concentrated and missed inspection occurs, and defective products are easy to flow out, thereby affecting the quality of the products.

In addition, the currently adopted method can only operate a single workpiece 100 for detection, is very time-consuming, cannot perform batch detection, and has extremely low detection efficiency.

The inventor has studied intensively, and invented the peripheral surface detection jig for the precision part provided by the embodiment of the application, which changes the traditional mode of carrying out peripheral surface detection by clamping a single workpiece 100 for rotation, and can carry out batch rotation operation on the workpiece 100 by using the peripheral surface detection jig to realize batch detection, thereby effectively solving the technical problems that the peripheral surface detection of the precision part in the prior art can only operate on the single workpiece 100 and is difficult to realize batch detection, and describing the technical problem in detail.

Referring to fig. 2 and 3, the fixture for detecting the outer peripheral surface of the precision component includes a tray 1, a detecting table 2, a base 3 and a collecting box 4.

As shown in fig. 3, the tray 1 is provided with a plurality of storage tanks 11 for filling the workpieces 100, the plurality of storage tanks 11 are arranged on the tray 1 side by side, and one side of the tray 1 is provided with a plurality of notches 12 communicated with the respective storage tanks 11. In this embodiment, the width of the stock chest 11 is matched with the thickness of the workpiece 100, the height of the stock chest 11 is matched with the diameter of the workpiece 100, and the notch 12 is matched with the shape of the stock chest 11, so that the workpiece 100 can be completely embedded in the stock chest 11, and can roll in the direction of the notch 12 when the tray 1 is tilted, and is output from the notch 12.

Referring to fig. 4, the inspection table 2 is provided with a mounting groove 21 and a detecting portion 22 for observing the outer peripheral surface of the workpiece 100, and the mounting groove 21 and the detecting portion 22 are provided adjacently on the inspection table 2. The detecting portion 22 is used for a detecting device, such as a microscope, to collect image information, and the collecting end of the detecting device may be directed toward the detecting portion 22 or mounted on the detecting portion 22 so as to detect the outer peripheral surface of the workpiece 100 located on the detecting portion 22.

The shape of the mounting groove 21 is matched with that of the tray 1, the tray 1 is detachably arranged in the mounting groove 21, and the notches 12 on the tray 1 are in one-to-one correspondence and communication with the detection grooves 221 on the detection part 22. The workpieces 100 loaded in the stock chest 11 can be rolled from the notches 12 on the tray 1 directly into the corresponding detection chest 221.

The detection table 2 is connected to the base 3 through a rotating shaft 23, so that the detection table 2 can be movably opened and closed on the base 3. This is understood here as: the detection table 2 can be operated to turn up on the base 3, so that the detection table 2 is inclined to the base 3; alternatively, the inspection station 2 can be laid flat on the base 3 when not operated.

Referring to fig. 5, 6 and 7, the base 3 is provided with a lever 31 for manual operation for rolling the workpiece 100, the lever 31 is located at the bottom of the detecting table 2, and at least part of the lever 31 can be in rolling contact with the workpiece 100 in the detecting groove 221. As shown in fig. 7, it can be understood here that: at least a part of the outer periphery of the lever 31 can be tangent to the outer peripheral surface of the workpiece 100. When the operator operates the operation lever 31 by hand to rotate, the workpiece 100 in the detection groove 221 can be simultaneously driven to roll forward or backward, so that the outer circumferential surface of the workpiece 100 can be detected by matching with the detection device.

Referring to fig. 5, 8 and 9, the collection box 4 is detachably disposed on the base 3 and below the inspection table 2, and the collection box 4 is used for collecting the workpieces 100 falling from the inspection groove 221. After the inspection table 2 is turned up, the workpiece 100 positioned in the inspection groove 221 can be naturally dropped into the collection box 4 to perform a discharging operation.

Compared with the prior art, the outer peripheral surface detection jig for the precise parts provided by the embodiment of the application has the advantages that the operation rod 31 is in rolling contact with the workpiece 100, the operation rod 31 can drive the workpiece 100 to roll during detection, the operation of clamping the workpiece 100 is not needed, the observed outer peripheral surface part on the workpiece 100 can be changed, the problem that the workpiece 100 needs to be subjected to rotation detection is solved, damage to the outer peripheral surface of the workpiece 100 is effectively avoided, and the yield is improved.

The tray 1 has a plurality of storage tanks 11, and when the tray 1 is mounted on the detection table 2, the storage tanks 11 correspond to the detection tanks 221 on the detection table 2, so that when the detection table 2 is operated, the workpieces 100 in each storage tank 11 can be automatically fed to each detection tank 221, the parts on the operating rod 31 are simultaneously in rolling contact with the workpieces 100 in each detection tank 221, and when the operating rod 31 is operated to rotate, the workpieces 100 can be synchronously driven to rotate, so that the observed positions of the outer peripheral surfaces of the workpieces 100 are synchronously changed, batch detection is realized, and the detection efficiency is effectively improved.

In the embodiment of the present application, referring to fig. 4, 6 and 8, the detecting portion 22 is provided with a plurality of marks 222 having the same number as the detecting grooves 221, and each mark 222 corresponds to a position of each detecting groove 221 one by one. The identifier 222 may be an arabic number, an english letter, a pattern, or the like, which is not particularly limited herein.

In this embodiment, the tray 1 has 10 storage tanks 11 thereon. In cooperation, the detection table 2 has 10 detection grooves 221, and the marks 222 on the detection table 2 are arabic numerals 1 to 10 for marking the 10 detection grooves 221. Therefore, in the detection process, if defective products are found, all defective products can be taken out through the corresponding marks 222 once after all detection is completed, so that quick detection and sorting are realized.

As shown in fig. 4, 8 and 9, since the detection table 2 is connected to the base 3 through the rotation shaft 23, the collection box 4 is detachably disposed on the base 3 and is located below the detection table 2. Therefore, the inspection table 2 can be turned up to empty the work 100 in the inspection groove 221 toward the collection box 4 for discharging. When the detection table 2 is reset, the workpieces 100 filled in the storage tank 11 on the material tray 1 roll into the detection tank 221 to realize automatic feeding, so that a new batch of workpieces 100 can be detected. The operation is repeated until the detection of the outer peripheral surface of the workpieces 100 filled on the tray 1 is finished in batches, so that the detection efficiency is effectively improved.

In the embodiment of the present application, referring to fig. 10, one end of each storage tank 11 on the tray 1 is a blind opening, the other end is communicated with the notch 12 at the corresponding position, and the inner bottom surface M of the storage tank 11 is inclined towards the direction of the notch 12. Thus, as shown in fig. 7, the round workpiece 100 filled in the stock tank 11 can roll along the inner bottom surface M of the stock tank 11 in the direction of the notch 12, and is automatically fed into the inspection tank 221.

Referring to fig. 3, the tray 1 is further provided with a blocking rod 13 for blocking the plurality of slots 12, the tray 1 is further provided with sliding grooves 14 located at two sides of the slots 12, the blocking rod 13 is provided with a sliding block 131, and the blocking rod 13 can slide in the sliding grooves 14 by the sliding block 131 to release or block the workpiece 100. In this way, the blocking rod 13 is used as a blocking member and is horizontally arranged in front of each notch 12 to block the workpiece 100 when the tray 1 is not mounted on the detection table 2, so as to prevent the workpiece 100 from directly falling out of the tray 1 from the notch 12.

As for the structure of the inspection table 2, in one embodiment of the present application, referring to fig. 3, 4 and 5, the inspection table 2 is provided with a side opening 24 communicating with the mounting groove 21, and the side opening 24 is provided on the inspection table 2 opposite to the inspection portion 22. Slide ways 25 are also respectively arranged on the inner walls of the two sides of the mounting groove 21 of the detection table 2, and the slide ways 25 extend from the side opening 24 of the detection table 2 to the direction of the detection part 22. The slide posts 15 for embedding the slide ways 25 are respectively arranged on two sides of the tray 1, so that the tray 1 can be embedded into the slide ways 25 on two sides of the mounting groove 21 by the slide posts 15, and is embedded into the mounting groove 21 of the detection table 2 from the side opening 24 of the detection table 2 along the slide ways 25 until the tray is abutted against the detection part 22.

In this embodiment, as shown in fig. 3 and 4, the mounting groove 21 of the detection table 2 is further provided with a positioning notch 211 located at one side of the side opening 24; the tray 1 is provided with a positioning block 16 for buckling the positioning notch 211 in a matched manner. Therefore, when the tray 1 is mounted on the detection table 2, the positioning block 16 is fastened with the positioning notch 211 in the mounting groove 21, so as to play a role in mounting and positioning.

In practical application, since the tray 1 is provided with the material blocking rods 13 capable of opening and closing the notches 12, when the tray 1 is installed on the detection table 2, the notch 12 needs to be opened by the material blocking rods 13 to release the workpiece 100 in the storage tank 11, so that the workpiece 100 is automatically fed into the detection tank 221.

In order to match the structure of the material blocking rod 13, in one embodiment of the present application, please refer to fig. 3, 4 and 11, the slideway 25 includes a pair of parallel grooves 251 and a connecting groove 252 connected between the pair of parallel grooves 251, one ends of the pair of parallel grooves 251 are respectively communicated with the connecting groove 252, and the other ends of the pair of parallel grooves 251 extend to the side opening 24 of the detecting platform 2, so as to form a U-shaped groove body transversely arranged on the inner side wall of the mounting groove 21. In addition, the detecting portion 22 is further provided with a step 223 located inside the mounting groove 21, and the stopper rod 13 on the tray 1 can rest on the step 223.

Thus, referring to fig. 3, 4 and 11, the slide 25 forms a U-shaped groove, and the pair of parallel grooves 251 are formed by two grooves with different heights, which are communicated with each other through the connecting groove 252. In the process of installing the tray 1 on the detection table 2, the tray 1 slides along the groove body positioned at the high position by the sliding columns 15 at the two sides to be installed in the installation groove 21, and the material blocking rod 13 is placed on the step 223 of the detection table 2; the spool 15 then moves along the connecting slot 252 from the high tank to the low tank to sink the entire tray 1. Since the stopper rod 13 is provided on the slide groove 14 of the side portion of the tray 1 through the slider 131, the stopper rod 13 is relatively moved on the notch 12 of the tray 1 while being rested by the step 223. It will be understood herein that the stop bar 13 is lifted by the step 223 to simultaneously open each notch 12 on the tray 1, so that the workpiece 100 in each storage tank 11 can naturally roll into the detection tank 221, thereby realizing automatic feeding.

In addition, in the process of operating the inspection table 2 to turn up on the base 3 so that the work 100 in the inspection groove 221 falls into the collection box 4, the work 100 of the rear row easily falls into the collection box 4 following the work 100 in the inspection groove 221 due to lack of blocking.

In this regard, in one embodiment of the present application, referring to fig. 11 and 12, the detecting portion 22 of the detecting table 2 is further provided with a movable cavity 26 and a blocking rod 27, and the movable cavity 26 is opened between the mounting groove 21 and the detecting groove 221. The blocking rod 27 is housed in the movable cavity 26 and can translate in the movable cavity 26 for blocking in front of the notch 12 of the tray 1. As shown in fig. 13, brackets 32 are provided on the base 3 at both sides of the inspection table 2, and both ends of the blocking rod 27 are penetrated from the side of the inspection table 2 and rest on the brackets 32 of the base 3.

As shown in fig. 7 and 11, when the inspection bench 2 is placed on the base 3, two ends of the material blocking rod 27 rest on the bracket 32 of the base 3, so that the material blocking rod 27 is positioned at the height of the movable cavity 26 to pass the workpiece 100, and the workpiece 100 can naturally roll into the inspection groove 221. As shown in fig. 9 and 14, when the detecting table 2 is turned up, the detecting table 2 is inclined to the base 3, and two ends of the blocking rod 27 are separated from the bracket 32 of the base 3, and the blocking rod 27 slides from the high position to the low position of the movable cavity 26 under the action of gravity and is just blocked in front of the notch 12 of the tray 1 due to the restriction of the movable cavity 26, so that the blocking rod 13 on the tray 1 is replaced to block the workpiece 100. Then, when the inspection bench 2 is placed on the base 3, the two ends of the material blocking rod 27 rest on the bracket 32 of the base 3, so that the material blocking rod 27 is reset, and the workpiece 100 is released again. In this way, in cooperation with the discharging operation of the detected workpiece 100, the material blocking lever 27 can prevent the workpiece 100 of the rear row from naturally falling to the collection box 4 following the workpiece 100 in the detection groove 221 when the detection table 2 is turned up.

In this embodiment, referring to fig. 12 and 15, the detecting portion 22 is further provided with a stopper 28 for limiting the displacement travel of the blocking rod 27, the stopper 28 is provided with a long hole 281, and the blocking rod 27 passes through the long hole 281 on the stopper 28 and extends out of the detecting table 2.

Because the movable cavity 26 is difficult to be matched with the bracket 32 on the base 3, the extension positions of the two ends of the material blocking rod 27 are further corrected by the limiting block 28, so that the two ends of the material blocking rod 27 smoothly extend out of the two sides of the detection table 2 and accurately rest on the bracket 32 on the two sides of the base 3, and the matching precision is effectively improved.
