Description

Technical Field

[0001] The utility model relates to the technical field of wear measurement, in particular to a chain wear measuring device. Background Art

[0002] Chains are a common transmission device and are widely used in mechanical equipment. The wear resistance, strength, and stability of chains directly affect the performance and life of the entire mechanical equipment. Therefore, accurately measuring the degree of chain wear is of great significance for ensuring the normal operation of the equipment, preventing failures, and extending the service life of the equipment. Wear measurement can measure the distance change between chain links with a vernier caliper, thereby reflecting the degree of chain wear.

[0003] The sprocket for placing the chain in the existing measuring device is inconvenient to install and remove, which is not conducive to quickly replacing sprockets with different gears to adapt to chains of different sizes, thereby reducing flexibility and operation in actual use. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the sprocket for placing the chain in the measuring device is inconvenient in installation and disassembly, which is not conducive to the rapid replacement of sprockets with different gears to adapt to chains of different sizes, thereby reducing the flexibility and operational shortcomings in actual use, and a chain wear measuring device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A chain wear measuring device includes a base;

[0007] Two sprockets are used to place chains. A slide groove is provided on the top of the base. Two mounting seats are provided above the base, and the bottom ends of the two mounting seats are slidably arranged inside the slide groove. The two sprockets are respectively located on one side of the two mounting seats;

[0008] The mounting mechanism is used to mount the sprocket on one side of the mounting seat. The mounting mechanism is respectively arranged on one side of the two sprockets. The mounting mechanism includes two mounting rods. The two mounting seats are respectively rotatably sleeved on the outer walls of the two mounting rods, and the two sprockets are respectively sleeved on the outer walls of the two mounting rods.

[0009] In a possible design, a limit strip is fixedly provided on the outer wall of the mounting rod, and a limit groove is provided on the inner wall of the sprocket, and the limit groove cooperates with the limit strip.

[0010] In a possible design, the mounting mechanism also includes two pressure rods, an inner cavity is opened at one end of the mounting rod, and one end of the two pressure rods is slidably arranged inside the two inner cavities respectively, and the same compression spring is fixedly arranged between the inner wall of one side of the inner cavity and one end of the pressure rod, and a clamping strip is provided inside the inner cavity, and a through hole is opened on the outer wall of the pressure rod, and the clamping strip is located inside the through hole, and an oblique strip is fixedly provided on the inner wall of one side of the through hole, and an oblique groove is opened on one side of the clamping strip, and the oblique groove cooperates with the oblique strip, and the bottom end of the clamping strip slides through to the outside of the mounting rod.

[0011] In one possible design, an inner rod is fixedly provided at one end of the pressure rod, and one end of the inner rod slides through the outside of the mounting rod. Baffles are fixedly provided on both sides of the top of the base, and one end of the two inner rods respectively cooperates with the two baffles.

[0012] In a possible design, a limiting ring is provided on the outer wall fixing sleeve of the mounting rod, and the limiting ring is located between the mounting seat and the sprocket.

[0013] In one possible design, a servo motor is fixedly installed on the top of the base, a mounting block is fixedly installed on one side of the mounting seat, a bidirectional threaded rod is fixedly installed on the output shaft of the servo motor, and the two mounting blocks are respectively threadedly mounted on the two ends of the outer wall of the bidirectional threaded rod.

[0014] In the present application, when used specifically, the servo motor is driven to rotate the bidirectional threaded rod, and the bidirectional threaded rod drives the two mounting blocks to move in opposite directions, the mounting block drives the mounting seat to move, and the mounting seat drives the mounting rod to move, thereby bringing the two sprockets closer inward. At this time, the chain can be put on the outer walls of the two sprockets, and then the servo motor is driven in the opposite direction to move the two sprockets outward to tighten the chain. After that, a tool such as a vernier caliper can be used to measure the change in the distance between the chain links, thereby reflecting the degree of wear of the chain. When it is necessary to replace sprockets of different sizes and tooth pitches, it is only necessary to drive the mounting seat inward. When the sprocket is removed and replaced, the pressure rod is reset by the compression spring, thereby driving the card strip to reset and re-fix the sprocket. When the mounting seat is located at the side to detect the chain, the inner rod will be within the range of the baffle. At this time, pressing the pressure rod will cause the inner rod at the other end to touch the baffle and cannot move, thereby avoiding the phenomenon that the sprocket fixed state is released due to accidental touching of the pressure rod.

[0015] In the present invention, the chain wear measuring device can be mounted on the side of the mounting seat by means of a fixing mechanism, and the corresponding fixing state can be released by pressing the pressure rod, so that sprockets of different sizes or tooth pitches can be replaced, thereby adapting to different types of chains and increasing the practicality of the device.

[0016] In the utility model, the chain wear measuring device can reflect the degree of chain wear by measuring the distance change between chain links after the chain is placed on the outer wall of the sprocket and tightened, through the measuring mechanism.

[0017] In the utility model, when in use, after the chain is placed on the outer walls of the two sprockets, the servo motor is driven to move the sprockets outward to tighten the chain, and the change in the distance between the chain links can be measured by a vernier caliper to reflect the degree of chain wear;

[0018] When the sprocket needs to be replaced to adapt to a different type of chain, just press the pressure bar to release the fixed state of the sprocket for replacement, which is simple and convenient and increases the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0025] Reference Figure 1-2 A chain wear measuring device, used in the wear measurement field, comprises a base 1, two sprockets 3, and a mounting mechanism. A chute 5 is defined at the top of the base 1, and two mounting blocks 6 are positioned above the base 1. The bottom ends of the two mounting blocks 6 are slidably mounted within the chute 5, allowing them to move along the chute 5. The two sprockets 3 are located on either side of the mounting blocks 6, respectively, for positioning the chain.

[0026] The mounting mechanism is used to mount the sprocket 3 on one side of the mounting seat 6. Specifically, the mounting mechanism includes two mounting rods 9, the two mounting seats 6 are rotatably sleeved on the outer walls of the two mounting rods 9, and the two sprockets 3 are also sleeved on the outer walls of the two mounting rods 9.

[0027] Reference Figure 3 In order to further fix the position of the sprocket 3 on the mounting rod 9, a limit strip 15 is fixedly provided on the outer wall of the mounting rod 9, and a limit groove is provided on the inner wall of the sprocket 3. The limit groove cooperates with the limit strip 15, thereby limiting the axial movement of the sprocket 3 on the mounting rod 9. Example

[0028] refer to Figure 3-4 , improved on the basis of Example 1: the mounting mechanism also includes two pressure rods 14, which are used to further fix the sprocket 3. An inner cavity 12 is provided at one end of the mounting rod 9, and one end of the two pressure rods 14 is slidably arranged inside the two inner cavities 12 respectively. A same compression spring 16 is fixedly arranged between the inner wall of one side of the inner cavity 12 and one end of the pressure rod 14, and the compression spring 16 provides elastic force for the pressure rod 14. A through hole 2 is provided on the outer wall of the pressure rod 14, and the clamping strip 13 inside the inner cavity 12 is located inside the through hole 2. An oblique strip 19 is fixedly provided on the inner wall of one side of the through hole 2, and an oblique groove 17 is provided on one side of the clamping strip 13, and the oblique groove 17 cooperates with the oblique strip 19. When the pressure rod 14 moves inward under external force, the oblique strip 19 will push the clamping strip 13 to move.

[0029] An inner rod 11 is fixed to one end of the pressure rod 14, and one end of the inner rod 11 slides through the outside of the mounting rod 9. Baffles 4 are fixed to both sides of the top of the base 1, and one end of the two inner rods 11 engages with the two baffles 4 respectively. When the two mounting seats 6 move along the slide 5 to a certain position, the two inner rods 11 come into contact with the two baffles 4, respectively, thereby limiting further movement of the mounting seats 6 and acting as a limiter.

[0030] The outer wall fixing sleeve of the mounting rod 9 is provided with a limiting ring 18, and the limiting ring 18 is located between the mounting seat 6 and the sprocket 3. The limiting ring 18 can prevent the sprocket 3 from excessively moving on the mounting rod 9, further ensuring the stability of the sprocket 3.

[0031] Reference Figure 2A servo motor 7 is fixed to the top of the base 1, and a mounting block 8 is fixed to one side of the mounting seat 6. A bidirectional threaded rod 10 is fixed to the output shaft of the servo motor 7, and two mounting blocks 8 are respectively threaded onto the outer ends of the bidirectional threaded rod 10. When the servo motor 7 is turned on, it drives the bidirectional threaded rod 10 to rotate, thereby driving the two mounting blocks 8 to move to the sides, and then driving the two mounting seats 6 and the sprocket 3 to move along the slide 5, thereby tightening and loosening the chain.

[0032] Specifically, the servo motor 7 is driven to drive the bidirectional threaded rod 10 to rotate, and the bidirectional threaded rod 10 drives the two mounting blocks 8 to move in opposite directions, and the mounting block 8 drives the mounting seat 6 to move, and the mounting seat 6 drives the mounting rod 9 to move, thereby bringing the two sprockets 3 closer inward. At this time, the chain can be put on the outer wall of the two sprockets 3, and then the servo motor 7 is driven in the reverse direction to move the two sprockets 3 outward to tighten the chain. After that, a tool such as a vernier caliper can be used to measure the change in the distance between the chain links, thereby reflecting the degree of wear of the chain. When it is necessary to replace the sprocket 3 of different size and tooth pitch, it is only necessary to drive the mounting seat 6 inward to move so that the inner rod 11 is within the range of the baffle 4. When the pressure rod 14 is pressed, the pressure rod 14 will drive the inclined bar 19 to move. Through the cooperation of the inclined bar 19 and the inclined groove 17, the card bar 13 will be pushed to move inward, so that the card bar 13 is retracted to the inside of the mounting rod 9. After that, the sprocket 3 can be removed for replacement. After that, the pressure rod 14 is reset by the compression spring 16, thereby driving the card bar 13 to reset and re-fix the sprocket 3. When the mounting seat 6 is located on the side to detect the chain, the inner rod 11 will be within the range of the baffle 4. At this time, the pressure rod 14 is pressed, and the inner rod 11 at the other end will touch the baffle 4 and cannot be displaced, thereby avoiding the phenomenon that the fixed state of the sprocket 3 is released due to accidental touching of the pressure rod 14.

[0033] However, as is well known to those skilled in the art, the working principle and wiring method of the servo motor 7 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
