Description

Technical Field

[0001] The invention relates to the technical field of track wheel measurement, and in particular to a double-sided track wheel body measurement device. Background Art

[0002] The track roller is used to support the weight of equipment such as excavators and tractors, and rolls on the track rails, such as the track links or track shoes. It is also used to limit the track to prevent lateral slippage. The track roller body is the outer shell of the track roller and is an important part of the track roller. Multiple track rollers need to be installed on each chassis system to transfer the weight of the locomotive group to the ground and roll on the track.

[0003] The roller body serves as the mounting base of the roller, and has high requirements on the accuracy of the inner hole. The existing method of measuring the hole diameter of the roller body is mainly to manually take a rocker table and contact the hole wall to measure the displacement, and then obtain the roundness of the measuring hole according to the measured displacement value by comparing with the standard part, that is, directly measure the size of the inner diameter. In order to ensure the accuracy of the measurement, the hole diameter needs to be measured multiple times and in multiple positions. However, when manual measurement is performed using a rocker table, operations such as reading need to be done manually, and the measurement accuracy and efficiency are relatively low. For this reason, the present application proposes a bilateral roller body measuring device. Summary of the invention

[0009] Preferably, a first spring is fixedly connected to the reflective sheet, the other end of the first spring is fixedly connected to the mounting plate, and the first spring is sleeved on the outside of the L-shaped measuring needle.

[0010] Preferably, the limiting mechanism includes a plurality of movable rods that pass through the transverse support plate and are slidably connected thereto and can be reset, a plurality of sleeves are penetrated on the mounting circular plate and are rotatably connected thereto, the sleeves and the movable rods are arranged opposite to each other, the interior of the sleeves is rectangular in shape, a support ring that abuts against the upper end of the mounting circular plate is fixed on the sleeve, four fixed blocks are fixed on the support ring, a rectangular rod that is slidably connected to the fixed block is penetrated on the fixed block, an arc block is fixed on the rectangular rod, a second spring is fixed on the arc block, the other end of the second spring is fixedly connected to the fixed block, a wedge block is fixed on the rectangular rod, the wedge block is located in the sleeve, a quadrangular pyramid is fixed on the upper end of the moving rod, the quadrangular pyramid is slidably connected in the sleeve and is arranged in cooperation with the wedge block.

[0011] Preferably, a fixed ring is fixedly connected to the bottom of the moving rod, a rotating ring located at the upper end of the fixed ring is fixed to the outer wall of the moving rod, a third spring is fixed on the rotating ring, the third spring is fixedly connected to the fixed ring, the rotating ring is rotatably connected to the bottom of the mounting circular plate, and a polygonal column groove is provided at the bottom of the moving rod.

[0012] Preferably, it also includes a driving mechanism capable of driving the shaft rod to rotate, the driving mechanism includes a motor fixed at the bottom of the mounting frame, the output end of the motor is fixedly connected to the driving shaft, a reduction box is installed on the mounting frame, the driving shaft is fixedly connected to the shaft end of the reduction box, a short shaft is fixed to the other shaft end of the reduction box, a first incomplete gear is fixed on the short shaft, a first gear is fixed on the shaft rod, and the first incomplete gear is meshed with the first gear.

[0013] Preferably, it also includes a transmission mechanism capable of driving the movable rod to rotate, the transmission mechanism includes a second incomplete gear fixed on the driving shaft, a piston cylinder is rotatably connected to the mounting frame, a second gear is fixed on the piston cylinder, the second incomplete gear is meshed with the second gear, a movable piston is slidably connected in the piston cylinder, a polygonal column is fixed on the movable piston, and the polygonal column is matched with the polygonal column groove.

[0014] Preferably, it also includes a delivery mechanism capable of delivering hydraulic oil into the piston cylinder, the delivery mechanism includes a pull rod fixed at the bottom of the electric slider, a horizontal plate is fixed to the bottom of the pull rod, a liquid storage bag is fixed on the horizontal plate, a limiting plate is fixed on the mounting plate, the liquid storage bag is fixedly connected to the limiting plate, a delivery pipe is connected to the liquid storage bag, and the delivery pipe is coaxially rotatably connected to the piston cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The downward movement of the limit plate will squeeze the reservoir bag, so that the hydraulic oil in the reservoir bag can be transported to the piston cylinder through the delivery pipe. The hydraulic oil in the piston cylinder increases and drives the moving piston to move upward. The moving piston moves upward and drives the polygonal column to move upward. The polygonal column moves upward and extends into the polygonal column groove to prepare for the subsequent synchronous rotation. The two can also be separated to avoid interfering with the rotation of the mounting circular plate.

[0017] 2. The four-sided pyramid moves upward and contacts the wedge block, causing the four wedge blocks to move in opposite directions. The movement of the wedge block drives the rectangular rod to move, and the movement of the rectangular rod drives the arc block. The arc block moves and contacts the inner wall of the track wheel, so that the track wheel can be positioned and is not easily moved.

[0018] 3. When the inner and outer walls of the track roller are deformed, with the cooperation of the first spring, the inner wall is concave, and the first spring pulls the reflective sheet and the L-shaped measuring needle to move. At this time, the distance between the laser emitter and the reflective sheet changes. When the inner wall is convex, it will drive the L-shaped measuring needle to move. The movement of the L-shaped measuring needle causes the distance between the laser emitter and the reflective sheet to change. In this way, the changing distance between the laser emitter and the reflective sheet can be continuously obtained. If the continuously changing distance between the laser emitter and the reflective sheet is within this error range, it means that the inner diameter of the track roller is qualified, otherwise it is unqualified.

[0019] 4. Place the L-shaped measuring needle against the outer wall of the track roller to measure the roundness of the outer wall of the track roller.

[0020] 5. The output end of the electric push rod moves up and resets, thereby driving the liquid storage bag to move up and reset, so that the polygonal column can be separated from the moving rod. Under the action of the third spring, the moving rod and the quadrangular pyramid can be reset, and under the action of the second spring, the arc block and the rectangular rod can be reset. In this way, the supporting wheels are no longer limited, so that subsequent staff can sort and deliver qualified and unqualified parts.

[0021] To sum up, the L-shaped measuring needle of the present invention is against the inner and outer walls of the supporting wheel, and the supporting wheel rotates in conjunction with the laser emitter and the reflective sheet, so that the roundness of the inner and outer walls of the supporting wheel can be continuously measured, avoiding the disadvantage of low efficiency of multiple manual measurements in the prior art, improving work efficiency, and being able to measure multiple randomly inspected supporting wheels one by one.

[0038] A plurality of limiting mechanisms for limiting the support wheels are fixed on the mounting circular plate 5, the limiting mechanisms include a plurality of movable rods 8 which penetrate the transverse support plate 6, are slidably connected thereto and are capable of being reset, a fixed ring 27 is fixedly connected to the bottom of the movable rod 8, a rotating ring 25 located at the upper end of the fixed ring 27 is fixed to the outer wall of the movable rod 8, a third spring 26 is fixed on the rotating ring 25, the third spring 26 is fixedly connected to the fixed ring 27, the rotating ring 25 is rotatably connected to the bottom of the mounting circular plate 5, and a polygonal column groove 28 is provided at the bottom of the movable rod 8.

[0039] The mounting circular plate 5 is penetrated by a plurality of sleeves 23 rotatably connected thereto. The sleeves 23 are arranged opposite to the moving rod 8. The interior of the sleeves 23 is in a rectangular shape. A support ring 22 abutting against the upper end of the mounting circular plate 5 is fixed on the sleeve 23. Four fixed blocks 29 are fixed on the support ring 22. The fixed block 29 is penetrated by a rectangular rod 30 slidably connected thereto. An arc block 32 is fixed on the rectangular rod 30. A second spring 33 is fixed on the arc block 32. The other end of the second spring 33 is fixedly connected to the fixed block 29. A wedge block 31 is fixed on the rectangular rod 30. The wedge block 31 is located in the sleeve 23. A quadrangular pyramid 24 is fixed on the upper end of the moving rod 8. The quadrangular pyramid 24 is slidably connected in the sleeve 23 and is arranged in conjunction with the wedge block 31.

[0040] It also includes a delivery mechanism capable of delivering hydraulic oil to the piston cylinder 42, the delivery mechanism includes a pull rod 15 fixed to the bottom of the electric slider 12, a horizontal plate 17 is fixed to the bottom of the pull rod 15, a liquid storage bag 21 is fixed on the horizontal plate 17, a limiting plate 20 is fixed on the mounting plate 13, the liquid storage bag 21 is fixedly connected to the limiting plate 20, a delivery pipe 7 is connected to the liquid storage bag 21, the delivery pipe 7 is coaxially rotatably connected to the piston cylinder 42, and the bottom of the piston cylinder 42.

[0041] The L-shaped measuring needle 14 is against the inner wall and outer wall of the supporting wheel, and the laser emitter 9 emits laser to the reflective sheet 18. In conjunction with the moving reflective sheet 18, it is possible to measure whether the inner wall and outer wall of the supporting wheel are perfect circles. The laser emitter 9 emits laser to the reflective sheet 18, and the laser returns. The round-trip distance can be obtained by multiplying the speed of light by time. Half of the round-trip distance is the distance between the laser emitter 9 and the reflective sheet 18.

[0042] When the present invention is used, the staff puts the roller to be measured on the support ring 22 and sleeves it on the outside of the arc block 32, and then starts the motor 10;

[0043] The motor 10 drives the driving shaft 38 to rotate, and the driving shaft 38 rotates to drive the reduction box 37 to rotate. The transmission of the reduction box 37 realizes the rotation of the short shaft 36. The short shaft 36 slowly rotates to drive the first incomplete gear 35 to rotate. The first incomplete gear 35 rotates to drive the first gear 34 to rotate. The first gear 34 rotates to drive the shaft rod 11 to rotate. The shaft rod 11 rotates to drive the mounting circular plate 5 to rotate. When the first incomplete gear 35 is not meshed with the first gear 34, one of the moving rods 8 is opposite to the polygonal column 41.

[0044] In the above, the second incomplete gear 39 does not mesh with the second gear 40;

[0045] The output end of the electric push rod 3 moves downward, driving the mounting plate 13, the mounting rod 16 and the laser transmitter 9 to move downward. Finally, the L-shaped measuring needle 14 is located in the inner hole of the supporting wheel. The mounting plate 13 moves downward, driving the limit plate 20 to move downward. Since the cross plate 17 will not move downward under the action of the pull rod 15, the limit plate 20 moves downward to squeeze the liquid storage capsule 21. In this way, the hydraulic oil in the liquid storage capsule 21 can be delivered to the piston cylinder 42 through the delivery pipe 7. The hydraulic oil in the piston cylinder 42 increases and drives the moving piston 43 to move upward. The moving piston 43 moves upward and drives the polygonal column 41 to move upward. The polygonal column 41 moves upward and extends into the polygonal column groove 28.

[0046] As the moving piston 43 continues to move upward, the polygonal column 41 drives the moving rod 8 and the quadrangular pyramid 24 to move upward, the quadrangular pyramid 24 moves upward and abuts against the wedge block 31, causing the four wedge blocks 31 to move in opposite directions, the movement of the wedge block 31 drives the rectangular rod 30 to move, the movement of the rectangular rod 30 drives the arc block 32, the arc block 32 moves and abuts against the inner wall of the supporting wheel, so that the supporting wheel can be positioned and prevented from moving easily;

[0047] The electric slider 12 moves on the electric slide rail 4, thereby driving the electric push rod 3 and the L-shaped measuring needle 14 to move, until the L-shaped measuring needle 14 abuts against the inner wall of the inner hole of the supporting wheel, and the movement of the L-shaped measuring needle 14 drives the reflective sheet 18 to move. At this time, the distance between the laser emitter 9 and the reflective sheet 18 is fixed;

[0048] At this time, the second incomplete gear 39 is meshed with the second gear 40, and the rotation of the second incomplete gear 39 drives the second gear 40 to rotate, and the rotation of the second gear 40 drives the piston cylinder 42 to rotate, and the rotation of the piston cylinder 42 drives the polygonal column 41 to rotate, and the rotation of the polygonal column 41 drives the moving rod 8 to rotate, and the rotation of the moving rod 8 drives the quadrangular pyramid 24 to rotate, and the rotation of the quadrangular pyramid 24 drives the sleeve 23 to rotate, and the rotation of the sleeve 23 drives the support ring 22 to rotate, and then drives the supporting wheel to rotate. The rotation of the supporting wheel causes the inner diameter inner wall and the position of the L-shaped measuring needle 14 to continuously change. Since the distance between the laser emitter 9 and the reflective sheet 18 is fixed, when the inner wall is concave or convex (this part is represented by the inner diameter In the case of not being a perfect circle), that is, when there is deformation, with the cooperation of the first spring 19, the inner wall is concave, the first spring 19 and the pull reflector 18 and the L-shaped measuring needle 14 move, and the distance between the laser emitter 9 and the reflector 18 changes. When the inner wall is convex, the L-shaped measuring needle 14 will be driven to move, and the movement of the L-shaped measuring needle 14 will cause the distance between the laser emitter 9 and the reflector 18 to change. In this way, the distance between the laser emitter 9 and the reflector 18 can be continuously obtained. If the error is ±0.1mm, and the continuously changing distance between the laser emitter 9 and the reflector 18 is within this error range, it means that the inner diameter of the supporting wheel is qualified, otherwise it is unqualified;

[0049] Similarly, by making the L-shaped measuring needle 14 butt against the outer wall of the track roller, the roundness of the outer wall of the track roller can be measured;

[0050] After the measurement is completed, the output end of the electric push rod 3 moves upward and resets, thereby driving the liquid storage bag 21 to move upward and reset, so that the polygonal column 41 can be separated from the moving rod 8. Under the action of the third spring 26, the moving rod 8 and the quadrangular pyramid 24 can be reset. Under the action of the second spring 33, the arc block 32 and the rectangular rod 30 are reset, so that the supporting wheel is no longer limited.

[0051] Next, the first gear 34 rotates to drive the shaft 11 to rotate, and the shaft 11 rotates to drive the mounting circular plate 5 to rotate. When the first incomplete gear 35 is not engaged with the first gear 34, one of the moving rods 8 is opposite to the polygonal column 41. The above work is repeated to measure the supporting wheels one by one. After the measurement, the staff sorts and delivers the qualified and unqualified parts.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
