Description

Technical Field

[0001] This application relates to the field of drill bit processing technology, and in particular to a detection device for detecting the end face of bar stock. Background Technology

[0002] PCB drill bits are one of the important tools used in PCB processing. The cemented carbide rods used in them are grooved to form a specific drill bit structure. In the initial processing stage, the raw material for the drill bit is the cemented carbide rod. The processing steps include inspecting the cut surface of the rod. Currently, the methods for judging whether the cut end face of the cemented carbide rod meets the requirements are generally visual inspection or measurement by a device. The accuracy and consistency of visual inspection are not good, so it is only suitable for a few cases. The accuracy of inspection by a detection device is better, but most of the current detection devices are only suitable for detecting rods with a single diameter, and it takes a long time to replace them. Utility Model Content

[0003] The purpose of this application is to provide a detection device for detecting the end face of bar stock, so as to solve at least one of the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, this application provides a detection device for detecting the end face of a bar stock, including a base, and an observation component, a positioning component and a length-fixing component sequentially arranged on the base along a first direction;

[0005] The positioning component includes a sliding block and a positioning block disposed on the sliding block. The sliding block is adapted to slide on the base along a second direction. The positioning block has a plurality of V-shaped grooves distributed at intervals along the second direction.

[0006] The length-fixing component includes a mounting base and a calibration block, wherein the calibration block is adapted to be slidably disposed on the mounting base along a first direction;

[0007] Wherein, the first direction and the second direction are perpendicular to each other;

[0008] In the above process, the operator places one end of the bar to be tested on the V-groove of the positioning block. The V-groove acts as a limiting element, and the end of the bar abuts against the side wall of the groove. The operator determines the length standard of the bar by observing the gap between the other end of the bar and the calibration block. Based on this, the end of the bar is observed through the observation component to achieve end detection. When testing bars of different sizes, the operator can move the sliding block along the second direction, thereby moving the positioning block so that the V-groove of the corresponding size is located below the observation component. Then, the bar of the corresponding size can be placed for testing, and the above process is repeated. Similarly, the position of the calibration block is adjustable and can be adjusted according to the actual measurement standard requirements. This solution can achieve rapid testing of bars and can also be flexibly and quickly adjusted for changes in the type of product being tested. It is easy to operate and effectively improves work efficiency.

[0009] Preferably, a positioning groove is formed on the side of the sliding block near the mounting base. Multiple positioning grooves are provided and are arranged corresponding to the V-shaped groove. The multiple positioning grooves are distributed at intervals along the second direction.

[0010] A positioning rod is provided on the mounting base along a first direction, and a positioning protrusion is formed on the side of the positioning rod near the sliding block. The positioning protrusion is adapted to the positioning groove.

[0011] In the above implementation process, when it is necessary to adjust the test slot position, first pull the positioning rod out towards the side of the original sliding block, so that the positioning protrusion leaves the positioning slot. Then move the sliding block to the appropriate position, and then push the positioning rod to make the positioning protrusion snap into the corresponding positioning slot again. At this time, the position of the sliding block can be fixed. This design realizes the locking / releasing of the sliding block through the insertion and removal action of the positioning rod, and the changeover time is shortened to 5 seconds, which is particularly suitable for small batch and multi-batch production scenarios.

[0012] Preferably, an extension block extending in the second direction is provided at the end of the positioning rod away from the positioning protrusion;

[0013] In the above implementation process, the positioning rod is further provided with an extension block extending in the second direction, which can provide the staff with a better point of force application and improve the convenience of the staff to operate the positioning rod.

[0014] Preferably, the positioning groove and the positioning protrusion are V-shaped;

[0015] In the above implementation process, this solution sets the positioning groove and the positioning block into a matching V-shaped structure, so that automatic compensation and correction can be achieved when the two are docked, thereby allowing the sliding block to quickly enter the designated position when the positioning rod is inserted, and realizing the rapid and accurate positioning of the positioning block.

[0016] Preferably, the size of some of the V-grooves gradually increases or decreases along the second direction;

[0017] In the above implementation process, this solution uses a gradual size variation to set the arrangement of the V-grooves, making it easier for staff to form memory points during operation, and thus making it easier to adjust the test size.

[0018] Preferably, a pull rod extending in the second direction is provided on the side wall of the sliding block;

[0019] Preferably, there are two pull rods, which are arranged opposite to each other on both sides of the sliding block;

[0020] In the above scheme, the levers provide a better point of force application for the operator, thereby better controlling the movement of the sliding block. In addition, the two levers are symmetrically distributed on both sides of the sliding block, supporting alternating operation with the left and right hands, thus improving the convenience of operation.

[0021] Preferably, a limiting groove is formed on the mounting base along the first direction, and a limiting block adapted to the limiting groove is provided at the bottom of the calibration block;

[0022] Fixing blocks are provided on both sides of the calibration block, and waist-shaped holes extending in the first direction are formed on the fixing blocks;

[0023] The mounting base has a plurality of mounting holes spaced apart along the movement trajectory of the fixing block; it also includes a fastener adapted to fix the fixing block through the oblong hole and the mounting holes;

[0024] Preferably, the mounting base has a scale marking on one side of the fixing block along a first direction;

[0025] In the above process, the limiting block and the limiting groove work together to limit the movement of the calibration block, allowing it to be stably adjusted along the first direction; the scale mark works with the stepless adjustment of the waist-shaped hole, and can be directly aligned with the scale line and locked, eliminating the need for repeated measurement with vernier calipers and improving work efficiency.

[0026] Preferably, the observation assembly includes a mounting frame and an observation mirror mounted on the mounting frame, the observation mirror being suspended above the positioning block.

[0027] Compared with the prior art, the beneficial effects of this application are as follows: This solution uses a design of multiple V-shaped grooves spaced apart on the sliding block, which allows the device to be compatible with bars of different diameters; in addition, it can realize rapid detection of the end face and length of the bar, and can make flexible and rapid adjustments for changes in the type of the tested product. It is easy to operate and effectively improves work efficiency. Attached Figure Description

[0037] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings: Example

[0038] PCB drill bits are one of the important tools used in PCB processing. The cemented carbide rods used in these drill bits undergo specific grooving to form a specific drill bit structure. In the initial processing stage, the raw material for the drill bit is the cemented carbide rod. The processing steps include inspecting the cut surface of the rod. Currently, methods for determining whether the cut surface of the cemented carbide rod meets the requirements generally rely on visual inspection or device measurement. Visual inspection has poor accuracy and consistency, and therefore is only applicable to a few situations. Inspection using a testing device offers better accuracy, but most current testing devices are only suitable for single-diameter rods, and replacement is time-consuming. To solve the above technical problems, this embodiment provides the following technical solution:

[0039] Please see Figure 1-3 This embodiment provides a detection device for detecting the end face of a bar stock, including a base 10, and an observation component 20, a positioning component 30 and a length-fixing component 40 sequentially arranged on the base 10 along a first direction;

[0040] Specifically, the positioning component 30 includes a sliding block 31 and a positioning block 32 disposed on the sliding block 31. The sliding block 31 is adapted to slide on the base 10 along the second direction, and the positioning block 32 has a plurality of V-shaped grooves 321 spaced apart along the second direction.

[0041] Specifically, the length-fixed component 40 includes a mounting base 41 and a calibration block 42, the calibration block 42 being adjustablely slidable on the mounting base 41 along a first direction;

[0042] In one embodiment, the first direction and the second direction are perpendicular to each other;

[0043] In the above scheme, the operator places one end of the bar to be tested on the V-groove 321 of the positioning block 32. The V-groove 321 provides a certain limiting function and abuts against the side wall of the groove at the end. The operator determines the length standard of the bar by observing the gap between the other end of the bar and the calibration block 42. Based on this, the end of the bar is observed through the observation component 20 to achieve end detection. When testing bars of different sizes, the operator can move the sliding block 31 along the second direction, thereby moving the positioning block 32 so that the V-groove 321 of the corresponding size is located below the observation component 20. Then, the bar of the corresponding size can be placed for testing, and the above process is repeated. Similarly, the position of the calibration block 42 is adjustable and can be adjusted according to the actual measurement standard requirements. This scheme can achieve rapid testing of bars and can also be flexibly and quickly adjusted for changes in the type of product being tested. It is easy to operate and effectively improves work efficiency.

[0044] In one embodiment, a slide rail 33 extending in a second direction is provided on the base 10, and a sliding block 31 is slidably disposed on the base 10 via the slide rail 33.

[0045] For details, please see Figure 3 A positioning groove 51 is formed on the side of the sliding block 31 near the mounting base 41. Multiple positioning grooves 51 are provided and are corresponding to the V-shaped groove 321. The multiple positioning grooves 51 are distributed at intervals along the second direction.

[0046] Furthermore, a positioning rod 52 is provided on the mounting base 41 along the first direction, and a positioning protrusion 53 is formed on the side of the positioning rod 52 near the sliding block 31. The positioning protrusion 53 is adapted to the positioning groove 51.

[0047] In the above scheme, when it is necessary to adjust the test slot position, first pull out the positioning rod 52 towards the side of the original sliding block 31, so that the positioning protrusion 53 leaves the positioning groove 51. Then move the sliding block 31 to the appropriate position, and then push the positioning rod 52 to make the positioning protrusion 53 snap into the corresponding positioning groove 51 again. At this time, the position of the sliding block 31 can be fixed. This design realizes the locking / releasing of the sliding block 31 through the insertion and removal action of the positioning rod 52, and the changeover time is shortened to 5 seconds, which is particularly suitable for small batch and multi-batch production scenarios.

[0048] Specifically, an extension block 421 extending in the second direction is provided at the end of the positioning rod 52 away from the positioning protrusion 53;

[0049] In the above scheme, the positioning rod 52 is further provided with an extension block 421 extending in the second direction, which can provide the operator with a better point of force application and improve the operator's convenience in operating the positioning rod 52.

[0050] Specifically, the positioning groove 51 and the positioning protrusion 53 are V-shaped;

[0051] In the above scheme, the positioning groove 51 and the positioning block 32 are set as a matching V-shaped structure, so that automatic compensation and correction can be achieved when the two are docked, thereby allowing the sliding block 31 to quickly enter the designated position when the positioning rod 52 is inserted, so as to achieve fast and accurate positioning of the positioning block 32.

[0052] Specifically, the size of several V-grooves 321 gradually increases or decreases along the second direction;

[0053] In the above scheme, the arrangement of the V-groove 321 is set in a gradually changing size manner, which makes it easier for the staff to form a memory point during operation, and thus makes it easier to adjust the test size.

[0054] Specifically, a pull rod extending in the second direction is provided on the side wall of the sliding block 31;

[0055] Furthermore, there are two pull rods, which are positioned opposite each other on both sides of the sliding block;

[0056] In the above scheme, the levers provide a better point of force application for the staff, thereby better controlling the movement of the sliding block 31. In addition, the two levers are symmetrically distributed on both sides of the sliding block 31, supporting alternating operation with the left and right hands, and improving the convenience of operation.

[0057] Specifically, a limiting groove 411 is formed on the mounting base 41 along the first direction, and a limiting block 422 adapted to the limiting groove 411 is provided at the bottom of the calibration block 42;

[0058] Furthermore, fixing blocks are provided on both sides of the calibration block 42, and waist-shaped holes 423 extending in the first direction are formed on the fixing blocks;

[0059] For details, please see Figure 2 The mounting base 41 has a plurality of mounting holes 412 spaced apart on the moving trajectory of the fixed block; it also includes a fastener suitable for fixing the fixed block through the oblong hole 423 and the mounting holes 412;

[0060] Specifically, a scale mark 413 is provided on one side of the fixing block on the mounting base 41 along the first direction;

[0061] In the above scheme, the limiting block 422 and the limiting groove 411 cooperate to realize the movement limit of the calibration block 42, so that it can be stably adjusted along the first direction; the scale mark 413 cooperates with the stepless adjustment of the waist-shaped hole 423, and can be directly aligned with the scale line and locked, without the need for repeated measurement with vernier calipers, thus improving work efficiency.

[0062] Furthermore, the observation component 20 includes a mounting frame 21 and an observation mirror 22 mounted on the mounting frame 21, with the observation mirror 22 suspended above the positioning block 32.

[0063] Understandably, the observation mirror 22 is the tube of the tool limiting mirror, and the operator can observe the gap between the end face of the bar to be tested and the standard end face of the calibration block 42 through the observation mirror 22.

[0064] Furthermore, in some implementations, the lens can be combined with the camera mechanism and the display screen can be used to magnify the display image, thus showing the detection image more clearly.
