Some special chains on the market, such as Figure 1 As shown, some of the pins are set to an extended structure, and the extended pins distributed at equal intervals are plugged into the sleeve on the inner side of the transmission belt for fixation. The chain is set on the side of the transmission belt, which can be easily cleaned and lubricated.

[0003] In the prior art, a Chinese invention with publication number CN107192552B discloses an automatic chain inspection machine, which can realize all-round continuous inspection of the chain on a single device, with high inspection accuracy, low missed inspection rate, and high work efficiency.

[0004] However, for some special chains, traditional inspection equipment is not convenient for accurately detecting the spacing between pins and the size of the pins themselves, resulting in the chain being unable to be installed due to dimensional incompatibility when connected to the transmission belt.

The pressure block is opposite to the end face of the extension pin. After the sliding seat moves and drives the sliding frame to fit the side of the chain body, the measurement value of the second detector is the moving distance of the pressure block.

A driving screw is fixedly provided through the middle of the worm wheel, and the driving screw is movably passed through the connecting bracket through a thread. Both ends of the driving screw are rotatably connected to the sliding seat.

[0015] Preferably, positioning frames are provided at both ends of the chain body, and the positioning frames are arranged in an "H" shape.

A mounting seat is provided on the outer side of the adjusting screw through a threaded sleeve, and the mounting seat is fixed on the workbench.

[0016] An intelligent automatic detection process for a chain, using the above-mentioned intelligent automatic detection equipment for the chain, specifically includes the following steps:

[0017] Step 1: Use two positioning brackets to tighten and straighten the chain body;

[0018] Step 2: Move the sliding seat closer to the chain body until the sliding frame fits against the side of the chain body, and the second detector measures the length of the exposed area of ​​the extension pin;

[0019] Step 3: Move the sliding frame downward, and the extension pin is inserted between the two clamping sliders from bottom to top. The detector measures the diameter of the extension pin. At the same time, the extension pin squeezes the horizontal adjustment frame until the extension pin corresponds to the middle of the horizontal adjustment frame. The laser rangefinder on the detection seat measures the distance between two adjacent extension pins.

[0020] Preferably, in step one, the positioning frame clamps and fixes the end of the chain body, and the staff turns the adjusting screw and pulls the positioning frame to move through the connecting chuck to adjust the distance between the two ends of the chain body until the chain body is straightened.

[0021] Preferably, in the step 2, the initial measurement value of detector 2 is calibrated to zero, the sliding seat moves close to the chain body under the thrust of the cylinder, the extended pin is inserted into the inner cavity of the guide transverse groove and supports the pressure block, thereby pushing the pressure block, the mounting frame and detector 2 to move. At this time, the pull wire on detector 2 is pulled out, and detector 2 measures the displacement distance L1 of the pressure block. The distance between the surface of the sliding frame and the initial position of the pressure block is recorded as L2. Therefore, the length dimension L of the exposed area of ​​the extended pin is L=L1+L2.

[0022] Preferably, in step three, the driving motor is first started to drive the rotating shaft to rotate, the worm is driven by meshing with the worm wheel, and the connecting bracket is driven by the thread of the driving screw to drive the sliding frame to move downward as a whole until the lower opening edge of the sliding frame is in contact with the extended pin.

[0023] Preferably, in step three, multiple clamping sliders are fitted together in sequence under the thrust of the connecting bracket. When the extended pin is stuck between any two adjacent clamping sliders, the two clamping sliders located at the outermost positions will move away from each other, and the value of the increase in the distance between the two is the diameter value of the extended pin. Therefore, after the initial data of the detector is zeroed, the subsequent measurement value is the diameter value of the extended pin.

[0024] Preferably, in step three, the sliding frame, the fixed cross plate, the connecting rod and the horizontal adjustment frame move downward synchronously. When the extended pin contacts and squeezes the lower inner wall of the horizontal adjustment frame, the horizontal adjustment frame, the connecting rod and the horizontal slider are driven to slide horizontally along the length direction of the fixed cross plate. At the same time, since the connecting rod and the detection seat remain movably connected, the connecting rod also drives the detection seat to slide horizontally along the length direction of the sliding seat. When the extended pin is located in the middle of the horizontal adjustment frame, the value measured by the laser rangefinder on the detection seat is the minimum distance S1 between the two detection seats, and the horizontal width of the detection seat itself is constant, recorded as twice S2, so the distance S between the two extended pins = S1 + S2.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The present invention fixes a fixed horizontal plate at the opening at the lower end of the inner cavity of the sliding frame, and a sliding sleeve on the outer side of the fixed horizontal plate is provided with a plurality of clamping slide blocks arranged side by side. The end of the fixed horizontal plate is provided with a connecting bracket for clamping the clamping slide block, and the lower end of the clamping slide block is in a "V" shape. The detector 1 itself and the pull wire end are respectively fixed on the two outermost clamping slide blocks. When the sliding frame moves from top to bottom, the extended pin can be arbitrarily stuck between the two adjacent clamping slide blocks. The detector 1 can accurately measure the diameter of the extended pin. In addition, a detection seat is provided below the sliding frame, and a laser rangefinder is provided on the side of the detection seat, which can measure the distance between the two adjacent extended pins. A detector 2 is provided in the sliding seat. The end of the extended pin abuts against the pressure block and pushes the detector 2 to move, so that the length of the exposed part of the extended pin can be measured. The entire measurement process has a high degree of automation and the measurement result is accurate, which avoids the problem of size mismatch during subsequent use.

DETAILED DESCRIPTION

[0039] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figures 1 to 11 , the present invention provides a technical solution:

[0041] Embodiment 1, an intelligent automatic detection device for a chain, includes: a workbench 1, a sliding frame 5, a detection seat 7 and a mounting frame 8.

[0042] Specifically, a sliding seat 4 is slidably provided on the workbench 1, and the sliding seat 4 can be displaced in a direction close to or away from the chain body 2. The chain body 2 is provided on one side of the sliding seat 4, and an extended pin 21 is provided on the chain body 2. Figure 1 As shown, in order to facilitate the connection between the chain 2 and the external transmission belt 3 and other conveying structures, some pins on the chain 2 need to be lengthened, and the lengthened pins 21 are plugged and fixed with the sleeves 31 on the inner side of the transmission belt 3. The chain 2 is set on the side of the transmission belt 3, which can be easily cleaned and lubricated. During actual installation and use, the length, diameter, and spacing between adjacent lengthened pins 21 will have a great impact on the installation and connection. Therefore, the relevant dimensions of the lengthened pins 21 need to be accurately measured during the production process.

[0043] Secondly, the sliding frame 5 is vertically slidably installed on one side of the sliding seat 4. The sliding frame 5 itself is a hollow structure and has an opening at the lower end. When the sliding frame 5 moves down, the end surface of the lower opening of the sliding frame 5 can be placed on the surface of the extended pin 21. A fixed cross plate 51 is fixed at the lower end opening of the inner cavity of the sliding frame 5. The outer sliding sleeve of the fixed cross plate 51 is provided with a plurality of clamping sliders 6 arranged side by side, and the lower end of the clamping slider 6 is set into a "V" shape. The outer sides of both ends of the fixed cross plate 51 are sleeved with connecting brackets 52, and the connecting brackets 52 press the clamping slider 6. When the sliding frame 5 moves down, the clamping slider 6 is driven to move down synchronously, and the extended pin 21 presses the adjacent ones from bottom to top. The two pressing sliders 6 are squeezed and separated from each other until the sides of the two pressing sliders 6 clamp the extension pin 21 from both sides. At this time, the distance between the two outermost pressing sliders 6 increases, and the increased size is exactly consistent with the diameter of the extension pin 21. A detector 1 61 is provided above the fixed horizontal plate 51. The detector 1 61 and the detector 2 82 mentioned below are both wire displacement sensors. The detector 1 61 itself and the wire end are respectively fixed on the two outermost pressing sliders 6. The detector 1 61 is used to measure the distance between the two outermost pressing sliders 6, and thus can measure the diameter of the extension pin 21.

[0044] Furthermore, the detection seat 7 is located below the sliding frame 5 and corresponds to the extended pin 21. A laser rangefinder is provided on the side of the detection seat 7. The laser rangefinder can measure the distance between two adjacent detection seats 7, thereby measuring the distance between two adjacent extended pins 21.

[0045] In addition, the mounting frame 8 is located in the inner cavity of the sliding seat 4, and a pressure block 81 and a second detector 82 are fixed on the mounting frame 8, and the wire end of the second detector 82 is fixed to the inner wall of the sliding seat 4. The mounting frame 8, the pressure block 81 and the second detector 82 move synchronously. When the pressure block 81 moves, its movement amount is measured by the second detector 82. The pressure block 81 is facing the end face of the extension pin 21. After the sliding seat 4 moves and drives the sliding frame 5 to fit the side of the chain body 2, the value measured by the second detector 82 is the moving distance of the pressure block 81. The moving distance of the pressure block 81 plus the distance between the initial position of the pressure block 81 and the surface of the sliding frame 5 is the length dimension of the exposed part of the extension pin 21, as shown in FIG. Figure 9 As shown, considering that after the detector 2 82 is installed, even if the pressure block 81 is in the initial position, the pull wire end on the detector 2 82 is still pulled out to a certain length, it is necessary to calibrate the initial measurement value of the detector 2 82 to zero. In addition, it should be known that when the pressure block 81 is in the initial position, the distance between the pressure block 81 and the surface of the sliding frame 5 is a known fixed value, which can be known through pre-measurement.

[0046] In order to limit the pressing slider 6, the fixed transverse plates 51 of the present application are provided with two, which are parallel to each other, to prevent the pressing slider 6 set on the outside thereof from rotating, ensuring that the pressing slider 6 can only slide along the length direction of the fixed transverse plate 51, and the lower end of the pressing slider 6 extends to the outside of the sliding frame 5, ensuring that the sliding frame 5 is in the process of moving downward, The pressing slider 6 can first contact the extension pin 21, and after the extension pin 21 squeezes and stretches any two adjacent pressing sliders 6, the extension pin 21 will contact The edge of the lower opening of the sliding frame 5. In addition, the sliding seat 4 is driven by a cylinder. A side plate 41 is fixed to the outer side of the lower half of the sliding seat 4, and a T-shaped slide groove is provided on the lower end surface of the side plate 41. A limit slider 74 adapted to the T-shaped slide groove is fixed to the surface of the detection seat 7. The side plate 41 and the sliding seat 4 are fixedly connected by bolts. The T-shaped slide groove is provided to cooperate with the limit slider 74 to ensure that the detection seat 7 is always suspended on the lower end surface of the side plate 41, and the detection seat 7 can only slide horizontally along the length direction of the side plate 41.

[0047] In order to ensure that the extended pin 21 corresponds to the middle area of ​​the detection seat 7, the present application also has a fixed horizontal plate 51 fixed in the inner cavity of the sliding frame 5, the horizontal adjustment frame 71 is set to a "V" shape with an opening downward, and a connecting rod 72 is fixed to the outside of the horizontal adjustment frame 71. Since the position of the extended pin 21 itself is uncertain, when the extended pin 21 contacts the horizontal adjustment frame 71, the extended pin 21 first squeezes the edge of the horizontal adjustment frame 71 and drives the horizontal adjustment frame 71 to move horizontally until the extended pin 21 keeps corresponding to the upper convex position of the middle part of the horizontal adjustment frame 71. A horizontal slider 73 is fixed to the upper end of the connecting rod 72, and the horizontal slider 73 is horizontally slidably connected to the fixed horizontal plate 51. The horizontal slider 73 can move along the fixed horizontal plate 51 The horizontal adjustment frame 71 and the connecting rod 72 can slide in the length direction but will not be separated from it. Therefore, the horizontal adjustment frame 71 and the connecting rod 72 can be suspended below the fixed horizontal plate 51. In addition, the horizontal slider 73 is provided with two lower ends, and the lower ends are movably inserted into the detection seat 7 from top to bottom. When the sliding frame 5 and the fixed horizontal plate 51 move downward and drive the horizontal adjustment frame 71 and the connecting rod 72 to move downward synchronously, the connecting rod 72 can be inserted into the detection seat 7 for extension and contraction. When the horizontal adjustment frame 71 moves horizontally, the horizontal adjustment frame 71 can push the detection seat 7 to slide horizontally through the connecting rod 72, thereby ensuring that the middle position of the detection seat 7 remains corresponding to the extension pin 21, so as to facilitate the subsequent use of the laser rangefinder on the side of the detection seat 7 to measure the distance between two adjacent extension pins 21.

[0048] In order to guide the vertical sliding of the sliding frame 5, the present application also has a guide vertical groove 42 and a guide transverse groove 43 running through the sliding seat 4, and a connecting bracket 52 is fixed on the sliding frame 5 and the fixed transverse plate 51. The connecting bracket 52 movably passes through the guide vertical groove 42 and extends to the inner cavity of the sliding seat 4. The cooperation between the connecting bracket 52 and the guide vertical groove 42 is used to guide and limit the sliding of the sliding frame 5. One end of the connecting bracket 52 is set to a "T" shape and buckled on the inner wall of the sliding seat 4 to prevent the connecting bracket 52 from sliding along its own length direction and causing the distance between the sliding frame 5 and the sliding seat 4 to change. The pressure block 81 and the detector 82 are respectively fixed on both sides of the mounting frame 8, and the pressure block 81 is movably inserted into the inner cavity of the guide transverse groove 43. Figure 9As shown, when the mounting bracket 8 fits against the inner wall of the sliding seat 4, the pressure block 81 can be inserted into the inner cavity of the guide transverse groove 43, and the detector 2 82 is away from the inner wall of the sliding seat 4, so that its wire end can be pulled out and fixed to the inner wall of the sliding seat 4. A guide rod 84 is movably provided on the mounting bracket 8, and a clamping spring 83 is sleeved on the outer side of the end of the guide rod 84, and one end of the clamping spring 83 presses the mounting bracket 8 to fit against the inner wall of the sliding seat 4. The guide rods 84 are arranged in groups of two, for a total of two groups, and the ends of the two guide rods 84 in each group are kept fixed by a connecting plate. The guide rods 84 themselves are fixedly connected to the sliding seat 4, and the clamping spring 83 always provides thrust, so that the mounting bracket 8 always has a tendency to move close to the inner wall of the sliding seat 4.

[0049] In order to drive the vertical displacement of the sliding frame 5, the present application also has a rotating shaft 44 rotatably installed in the inner cavity of the sliding seat 4, and the rotating shaft 44 is driven to rotate by a driving motor 45 fixed to one end of the sliding seat 4, and a worm 46 is provided on the rotating shaft 44, and a worm wheel 47 is meshed with the outer side of the worm 46, as shown in FIG. Figure 7 As shown, when the rotating shaft 44 rotates, the meshing transmission between the worm 46 and the worm wheel 47 can drive the worm wheel 47 to rotate. A driving screw 48 is fixedly provided in the middle of the worm wheel 47, and the driving screw 48 movably penetrates the connecting bracket 52 through a thread. Both ends of the driving screw 48 are rotatably connected to the sliding seat 4. When the worm wheel 47 rotates, the thread on the driving screw 48 can drive the connecting bracket 52 to move up and down, thereby realizing the up and down movement of the sliding frame 5. Since the meshing transmission between the worm 46 and the worm wheel 47 is unidirectional, when the rotating shaft 44 stops rotating, the worm wheel 47 can maintain a stable position, thereby preventing the sliding frame 5 from easily moving up and down.

[0050] In order to tighten and straighten the chain body 2, the present application also has positioning frames 9 provided at both ends of the chain body 2, the positioning frames 9 are arranged in an "H" shape, one end of the positioning frame 9 is provided with a connecting slot 91, and a through hole 92 is provided in the middle of the positioning frame 9, a connecting chuck 94 is rotatably installed in the inner cavity of the connecting slot 91, an adjusting screw 93 is fixed on one side of the connecting chuck 94, and a limiting disc 95 is fixed on the other side of the connecting chuck 94 by a bolt, and the limiting disc 95 is located in the inner cavity of the through hole 92 and rotates The outer side of the adjusting screw 93 is provided with a mounting seat through a threaded sleeve, and the mounting seat is fixed on the workbench 1. A threaded insert is provided on the side of the positioning frame 9. By screwing the threaded insert, one end of the chain body 2 can be laterally pressed to achieve the clamping of the positioning frame 9 on the end of the chain body 2. When the staff tightens and straightens the chain body 2, they only need to screw the adjusting screw 93 and drive the positioning frame 9 to move, so as to apply tension to it from both ends of the chain body 2 and achieve the straightening of the chain body 2.

[0051] The present invention also discloses an intelligent automatic detection process for a chain, using the intelligent automatic detection device for the chain, which specifically includes the following steps:

[0052] Step 1: Use two positioning frames 9 to tighten and straighten the chain body 2. The positioning frames 9 clamp and fix the ends of the chain body 2. The staff turns the adjustment screw 93 and pulls the positioning frames 9 through the connecting chuck 94 to adjust the distance between the two ends of the chain body 2 until the chain body 2 is straight.

[0053] Step 2: Move the sliding seat 4 close to the chain body 2 until the sliding frame 5 is in contact with the side of the chain body 2. The second detector 82 measures the length of the exposed area of ​​the extension pin 21. It should be noted that the sliding seat 4 moves close to the chain body 2 under the thrust of the cylinder. The extension pin 21 is inserted into the inner cavity of the guide transverse groove 43 and presses against the pressure block 81, pushing the mounting frame 8 and the second detector 82 to move. At this time, the pull wire on the second detector 82 is pulled out, and the second detector 82 measures the distance L1 between itself and the inner wall of the sliding seat 4. Since the distance between the surface of the sliding frame 5 and the inner wall of the sliding seat 4 is constant and recorded as L2, the length dimension L of the exposed area of ​​the extension pin 21 is L=L1+L2;

[0054] Step 3: The sliding frame 5 moves downward, and the extended pin 21 is inserted between the two pressing slide blocks 6 from bottom to top. The detector 1 61 measures the diameter of the extended pin 21. At the same time, the extended pin 21 presses the horizontal adjustment frame 71 until the extended pin 21 is aligned with the middle of the horizontal adjustment frame 71. The laser rangefinder on the detection base 7 measures the distance between two adjacent extended pins 21.

[0055] First, the drive motor 45 is started to rotate the rotating shaft 44. The worm 46 is meshed with the worm gear 47, and the connecting bracket 52 is driven by the thread of the drive screw 48 to move the sliding frame 5 downward until the lower opening edge of the sliding frame 5 is in contact with the extended pin 21.

[0056] Since the multiple pressing sliders 6 are sequentially fitted together under the thrust of the connecting bracket 52, when the extended pin 21 is inserted between any two adjacent pressing sliders 6, the two pressing sliders 6 at the outermost positions will move away from each other, and the value by which the distance between them increases is the diameter value of the extended pin 21. Therefore, after the initial data of the detector 1 61 is zeroed, the subsequent measurement value is the diameter value of the extended pin 21.

[0057] In addition, the sliding frame 5, the fixed cross plate 51, the connecting rod 72 and the horizontal adjustment frame 71 move downward synchronously. When the extension pin 21 contacts and squeezes the lower inner wall of the horizontal adjustment frame 71, the horizontal adjustment frame 71, the connecting rod 72 and the horizontal slider 73 are driven to slide horizontally along the length direction of the fixed cross plate 51. At the same time, since the connecting rod 72 and the detection seat 7 remain movably connected, the connecting rod 72 also drives the detection seat 7 to slide horizontally along the length direction of the sliding seat 4. When the extension pin 21 is located in the middle of the horizontal adjustment frame 71, the value measured by the laser rangefinder on the detection seat 7 is the minimum distance S1 between the two detection seats 7, and the horizontal width of the detection seat 7 itself is constant, recorded as twice S2, so the distance S between the two extension pins 21 is S1+S2.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
