DETAILED DESCRIPTION

[0073] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0074] like Figures 1 to 16 A rack meshing instrument is shown, comprising:

[0075] A machine base 1, wherein the machine base 1 is provided with a table top 2;

[0076] A clamping seat 3, the clamping seat 3 is slidably connected to the right side of the top of the table 2;

[0077] Two clamping arms 4, the two clamping arms 4 are symmetrically slidably connected to the top of the clamping seat 3, and the two clamping arms 4 jointly clamp the rack 5 to be measured;

[0078] Two first driving wheels 6, the two first driving wheels 6 are rotatably connected to the top inner side walls of the two clamping arms 4 respectively;

[0079] The support platform is fixedly connected to the right side of the clamping seat 3, and a groove matching the rack 5 to be measured is provided on the top of the support platform 7;

[0080] A support frame 8, the top of the support frame 8 is symmetrically fixedly connected to the base 1, and cylinders 9 are symmetrically fixedly connected to both sides of the support frame 8, and the bottom end of the telescopic rod of the cylinder 9 is fixedly connected to a shell 10, and both upper and lower ends of the shell 10 are provided with through grooves;

[0081] A first flip clamping mechanism, which is used to clamp the rack 5 to be measured at the bottom of the limiting housing 10, so that the rack 5 to be measured at the bottom of the housing 10 cannot fall;

[0082] A second flip clamping mechanism, which is used to clamp the rack 5 to be measured in the limit housing 10 so that the rack 5 to be measured in the housing 10 cannot fall to the bottom of the housing 10;

[0083] Specifically, in the prior art, during the process of measuring the rack, the rack to be measured needs to be manually placed on the clamping seat 3, and one side of the rack teeth to be measured needs to be placed upwards, and the rack to be measured is removed from the clamping seat 3 after the measurement is completed, and then a new rack to be measured is replaced; however, since only one side of the rack has teeth that can mesh with the gear, the position of the rack needs to be adjusted each time it is installed, thereby increasing the difficulty of installing the rack, which is not conducive to rapid measurement of the rack. The present technical solution can solve the above problem. The specific operation is as follows: first, multiple racks to be measured are placed in the housing 10, When the rack needs to be measured, the cylinder 9 is first started, so that the telescopic rod of the cylinder 9 pushes the housing 10 to move downward, so that the bottom of the housing 10 is close to the clamping seat 3. In the process of the housing 10 moving downward to the clamping seat 3, the second flip clamping mechanism is first started to limit the rack 5 to be measured in the housing 10, so that the rack 5 to be measured in the housing 10 cannot fall to the bottom of the housing 10, and then the first flip clamping mechanism is started, so that the first flip clamping mechanism cancels the limiting effect on the rack 5 to be measured at the bottom of the housing 10, and under the action of gravity, the rack 5 to be measured at the bottom of the housing 10 falls on the clamping seat 3;

[0084] Then, the housing 10 is moved upward by starting the cylinder 9. During the upward movement of the housing 10, the first flip clamping mechanism is first started, so that the rack 5 to be measured at the bottom of the housing 10 is limited and cannot fall. Then, the second flip clamping mechanism is started to cancel the limit of the rack 5 to be measured inside the housing 10. The rack 5 to be measured in the housing 10 moves downward under the action of gravity and is clamped and limited by the first flip clamping mechanism.

[0085] When the housing 10 is reset upward, the two clamping arms 4 are started so that the two clamping arms 4 approach each other and finally clamp the rack to be measured. After clamping, the first driving wheel 6 is started to rotate, and the rack 5 to be measured is driven to rotate by the two first driving wheels 6, which is helpful to assist in adjusting the rack 5 to be measured and adjust the rack 5 to be measured to a specified position.

[0086] It should be noted that the two clamping arms 4 are moved closer to each other and pushed by a hydraulic cylinder, and the first driving wheel 6 is driven to rotate by a built-in motor.

[0087] As a further embodiment of the present invention, the first flip clamping mechanism comprises:

[0088] Two first flip plates 11, the two first flip plates 11 are symmetrically rotatably connected to the inner side wall of the housing 10;

[0089] Two connecting frames 12, one end of the connecting frame 12 is fixedly connected to the outer wall of the first flip plate 11, and the other end of the connecting frame 12 is rotatably connected to the second drive wheel 13, and the second drive wheel 13 contacts the surface of the rack 5 to be measured at the bottom of the housing 10;

[0090] A first flip driving component, the first flip driving component is used to drive the first flip plate 11 to flip;

[0091] Specifically, since the rack 5 to be measured is artificially placed into the housing 10, it is difficult to determine the position of the teeth of the rack 5 to be measured, thereby increasing the difficulty of adjusting the rack 5 to be measured. The technical solution can solve the above problem. The specific operation is as follows: by setting the first flip plate 11 and the second drive wheel 13, when the housing 10 moves downward, the first flip drive assembly is started to flip the two first flip plates 11 into a vertical state, thereby canceling the limiting effect on the rack 5 to be measured at the bottom of the housing 10. Under the action of gravity, the rack 5 to be measured at the bottom of the housing 10 falls on the clamping seat 3;

[0092] During the upward movement of the housing 10, the first flip driving assembly is activated to flip the two first flip plates 11 into an inclined state, thereby limiting the rack 5 to be measured at the bottom of the housing 10 so that it cannot fall;

[0093] After the two first flip plates 11 are flipped to an inclined state, the second driving wheel 13 is started to rotate the two driving wheels, so that the rack 5 to be measured at the bottom of the shell 10 rotates. When the side of the rack 5 to be measured with the teeth faces downward, the two second driving wheels 13 are not in contact with the rack 5 to be measured. Since the tooth part is a plane, the teeth of the rack 5 to be measured placed on the clamping seat 3 are facing downward each time. Then, the rack 5 to be measured is rotated 180 degrees by the first driving wheel 6, so that the teeth of the rack 5 to be measured are adjusted to the specified position.

[0094] It should be noted that the second drive wheel 13 is driven to rotate by a drive motor.

[0095] As a further embodiment of the present invention, the second flip clamping mechanism comprises:

[0096] Two second flip plates 14, the two second flip plates 14 are located directly above the two first flip plates 11, and the two second flip plates 14 are symmetrically rotated and connected to the inner side wall of the housing 10;

[0097] A second flip driving component, the second flip driving component is used to drive the second flip plate 14 to flip;

[0098] Specifically, by providing the second flip plate 14 and the second flip driving assembly, when the shell 10 moves downward toward the clamping seat 3, the second flip driving assembly is first started to flip the two second flip plates 14 into an inclined state, and the rack 5 to be measured in the shell 10 is limited, so that the rack 5 to be measured in the shell 10 cannot fall to the bottom of the shell 10, and then the first flip driving assembly is started to flip the two first flip plates 11 into a vertical state, thereby canceling the limiting effect on the rack 5 to be measured at the bottom of the shell 10, and under the action of gravity, the rack 5 to be measured at the bottom of the shell 10 falls onto the clamping seat 3;

[0099] During the upward movement of the shell 10, the two first flip plates 11 are flipped into an inclined state through the first flip driving assembly, thereby limiting the rack 5 to be measured at the bottom of the shell 10 and preventing it from falling. Then the second flip driving assembly is started to flip the two second flip plates 14 into a vertical state. Under the action of gravity, the rack 5 to be measured in the shell 10 moves downward to the bottom of the shell 10 to prepare for the next replacement of the rack.

[0100] As a further embodiment of the present invention, it also includes:

[0101] Two mounting posts 15, the two mounting posts 15 are symmetrically fixedly connected to the left side of the top of the table top 2;

[0102] A sliding seat 16, two ends of the left side of the sliding seat 16 are respectively slidably connected to the two mounting posts 15, and a standard gear 17 is provided on the right side of the sliding seat 16;

[0103] A pressure spring 18, the bottom end of the pressure spring 18 is fixedly connected to the sliding seat 16, the top end of the pressure spring 18 is fixedly connected to a pressure sensor 19, and the pressure sensor 19 is fixedly connected to the machine base 1;

[0104] Specifically, after the rack 5 to be measured is clamped by the clamping seat 3, the clamping seat 3 is started to move to the left, so that the rack 5 to be measured moves to the left and meshes with the standard gear 17 on the path. Through the change of the center distance during the meshing and moving process of the rack, the pressure sensor 19 measures a continuous pressure value parameter, so that it is possible to calculate and judge whether the rack 5 to be measured meets the standard based on the continuous pressure value.

[0105] The clamping seat 3 is driven by the guide rail so that the clamping seat 3 moves along a straight line.

[0106] As a further embodiment of the present invention, it also includes:

[0107] A first drive motor 20, which is fixedly connected to the right bottom end of the sliding seat 16, and an output shaft of the first drive motor 20 passes through the bottom end of the sliding seat 16 and is fixedly connected to a U-shaped mounting seat 21, and both ends of the standard gear 17 are rotatably connected to the inner wall of the U-shaped mounting seat 21;

[0108] Specifically, by providing the first drive motor 20 and the U-shaped mounting seat 21, the angle of the standard gear 17 can be adjusted according to the different angles of the tooth grooves of the rack 5 to be measured, so that the gear and the rack are fully meshed, which is beneficial to reduce measurement errors.

[0109] As a further embodiment of the present invention, it also includes:

[0110] A material drop chute 22, which is provided on the top of the table 2;

[0111] A receiving plate 23, which is rotatably connected to the bottom of the table 2 corresponding to the position of the material drop chute 22;

[0112] A second drive motor 24, the second drive motor 24 is fixedly connected to the inner wall of the table 2, and the second drive motor 24 is fixedly connected to the receiving plate 23;

[0113] Two discharge troughs 25, the two discharge troughs 25 are symmetrically arranged on both sides of the table 2, wherein both sides of the receiving plate 23 extend out of the discharge troughs 25;

[0114] Two material receiving boxes 26, the two material receiving boxes 26 are fixedly connected to the side wall of the table 2 at positions corresponding to the two material discharge slots 25;

[0115] Specifically, by setting a receiving plate 23 and a second driving motor 24, when the measurement is completed, the two clamping arms 4 move away from each other to cancel the clamping of the rack 5 to be measured, and the rack 5 to be measured falls to the receiving plate 23 through the dropping trough 22, and whether the rack 5 to be measured meets the standard is judged according to the measurement result. If it does not meet the standard, the second driving motor 24 is started to make the receiving plate 23 tilt to one side, so that the rack 5 to be measured falls into the receiving box 26 at the corresponding position. If it meets the standard, the receiving plate 23 tilts to the other side, so that the rack 5 to be measured falls into the receiving box 26 at the corresponding position, so that the rack 5 to be measured can be classified and collected.

[0116] As a further embodiment of the present invention, the first flip drive assembly includes:

[0117] Two first rotating seats 27, the two first rotating seats 27 are symmetrically fixedly connected to the inner wall of the housing 10, and the first flip plate 11 is rotatably connected to the first rotating seats 27 at corresponding positions;

[0118] A first torsion spring 28, two ends of which are fixedly connected to the first rotating seat 27 and the first flip plate 11 respectively;

[0119] A first push plate 29, one end of which penetrates through the inner wall of the housing 10 and contacts the side wall of the first flip plate 11, and the other end of the first push plate 29 is symmetrically fixedly connected to two first driving plates 30;

[0120] A first driving groove 31, which is provided on the first driving plate 30, and has a first straight groove 3101, a first inclined groove 3102, and a second straight groove 3103;

[0121] A U-shaped driving frame 32, the top of the U-shaped driving frame 32 is fixedly connected to the supporting frame 8, the bottom of the U-shaped driving frame 32 is fixedly connected to a first connecting pin 33, and the first connecting pin 33 is slidably connected in the first driving groove 31;

[0122] Specifically, when the housing 10 moves downward, the first driving plate 30 moves downward, so that the first connecting pin 33 first moves along the first straight groove 3101 and then enters the first inclined groove 3102. Under the action of the first inclined groove 3102, the first pushing plate 29 moves away from the first flip plate 11. Under the action of the first torsion spring 28, the first flip plate 11 flips and returns to a vertical state, and the first connecting pin 33 moves along the second straight groove 3103.

[0123] During the upward movement of the shell 10, the first driving plate 30 moves upward, so that the first connecting pin 33 first moves along the second straight groove 3103 into the first inclined groove 3102. Driven by the first inclined groove 3102, the first push plate 29 pushes the first flip plate 11, so that the first flip plate 11 flips and assumes an inclined state, thereby limiting the rack 5 to be measured at the bottom of the shell 10.

[0128] A second driving groove 39, which is provided on the second driving plate 38, and has a second inclined groove 3901 and a third straight groove 3902;

[0129] A second connecting pin 34 is fixedly connected to the side wall of the bottom end of the U-shaped driving frame 32, and the second connecting pin 34 is slidably connected in the second driving groove 39;

[0130] Specifically, by providing the second push plate 37 and the second drive slot 39, when the housing 10 moves downward, the first connecting pin 33 first moves along the first straight slot 3101, and at this time, the second connecting pin 34 moves along the second inclined slot 3901. Driven by the second inclined slot 3901, the second push plate 37 pushes the second flip plate 14, so that the second flip plate 14 flips to an inclined state, and the rack 5 to be measured in the housing 10 is limited, and then the second connecting pin 34 moves along the third straight slot 3902;

[0131] When the second connecting pin 34 moves along the third straight groove 3902, the first connecting pin 33 moves along the first inclined groove 3102. Driven by the first inclined groove 3102, the first push plate 29 moves away from the first flip plate 11. Under the action of the first torsion spring 28, the first flip plate 11 flips to a vertical state, thereby canceling the limit of the rack 5 to be measured at the bottom of the housing 10.

[0132] During the upward movement of the housing 10 , under the same principle as above, the first flip plate 11 is first flipped to an inclined state, and then the second flip plate 14 is flipped to a vertical state.

[0136] A return spring 42, both ends of which are fixedly connected to the sliding platform 40 and the U-shaped support platform 41;

[0137] Specifically, by providing a U-shaped support platform 41, it is helpful to avoid the possibility of the rack 5 to be measured being tilted when the rack 5 to be measured is placed on the clamping seat 3. At the same time, when the clamping seat 3 moves to the left and passes through the U-shaped support platform 41, the U-shaped support platform 41 moves to the left synchronously, and the reset spring 42 is compressed. After the measurement is completed, the clamping seat 3 is reset, and under the action of the reset spring 42, the U-shaped support platform 41 is reset.

[0138] As a further embodiment of the present invention, it also includes:

[0139] A fixing seat 43, the fixing seat 43 is located on the right side of the clamping seat 3, and the fixing seat 43 is fixedly connected to the table top 2;

[0140] An electric telescopic rod 44, the electric telescopic rod 44 is fixedly connected to the fixing seat 43, and the telescopic end of the electric telescopic rod 44 passes through the fixing seat 43 and is fixedly connected to a pushing block 45;

[0141] Specifically, by setting an electric telescopic rod 44 and a pushing block 45, after the measurement is completed, the electric telescopic rod 44 is started, so that the pushing block 45 pushes the rack 5 to be measured to move to the left, so that the right end of the rack 5 to be measured falls off the supporting platform 7, thereby causing the rack 5 to be measured to lose balance. Under the action of gravity, the rack 5 to be measured detaches from the U-shaped supporting platform 41, falls onto the receiving plate 23, and finally falls into the corresponding receiving box 26 according to the standard.

[0142] The working principle of the present invention is as follows: first, a plurality of racks to be measured are placed in the housing 10. When the racks need to be measured, the cylinder 9 is first started, so that the telescopic rod of the cylinder 9 pushes the housing 10 to move downward, so that the bottom of the housing 10 is close to the clamping seat 3. In the process of the housing 10 moving downward close to the clamping seat 3, the second flip clamping mechanism is first started to limit the rack 5 to be measured in the housing 10, so that the rack 5 to be measured in the housing 10 cannot fall to the bottom of the housing 10. Then, the first flip clamping mechanism is started, so that the first flip clamping mechanism cancels the limiting effect on the rack 5 to be measured at the bottom of the housing 10. Under the action of gravity, the rack 5 to be measured at the bottom of the housing 10 falls onto the clamping seat 3.

[0143] Then, the housing 10 is moved upward by starting the cylinder 9. During the upward movement of the housing 10, the first flip clamping mechanism is first started, so that the rack 5 to be measured at the bottom of the housing 10 is limited and cannot fall. Then, the second flip clamping mechanism is started to cancel the limit of the rack 5 to be measured inside the housing 10. The rack 5 to be measured in the housing 10 moves downward under the action of gravity and is clamped and limited by the first flip clamping mechanism.

[0144] When the housing 10 is reset upward, the two clamping arms 4 are started so that the two clamping arms 4 approach each other and finally clamp the rack to be measured. After clamping, the first driving wheel 6 is started to rotate, and the rack 5 to be measured is driven to rotate by the two first driving wheels 6, which is helpful to assist in adjusting the rack 5 to be measured and adjust the rack 5 to be measured to a specified position.

[0145] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
