Description

Technical Field

[0001] This utility model relates to the technical field of chain detection devices, and in particular to a chain center distance detection device. Background Technology

[0002] Chains are circular objects, mostly used for mechanical transmission and traction. The center distance of the chain is one of the key indicators of a chain.

[0003] CN210220979U discloses a chain center distance measuring instrument. The instrument includes a measuring device and a cabinet for housing the measuring device. The measuring device consists of a base plate and two sliding plates mounted on the base plate that can move back and forth. These sliding plates are a left sliding plate and a right sliding plate. Clearly, the chain center distance measuring instrument is relatively large and inconvenient to move. Furthermore, because the base plate is horizontally mounted on the cabinet surface, and the two sliding plates move along a horizontal plane on the base plate, the measuring device occupies a large area, making it unsuitable for use in small spaces such as laboratories or sampling inspection stations.

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] refer to Figures 1 to 3 A preferred embodiment of the chain center distance detection device according to this utility model will be described in detail below. The chain center distance detection device includes a main body 10, a bearing mechanism 20, a belt shifting mechanism 30, and a measuring mechanism 40.

[0025] The supporting mechanism 20 includes a static mounting component 21 and a movable mounting component 22. The equipment body 10 includes a support member 11 and a mounting member 12. The mounting member 12 is mounted on the support member 11 and has a high end portion 121 and a low end portion 122 below the high end portion 121. The static mounting component 21 is fixedly mounted on the mounting member 12, and the movable mounting component 22 is slidably mounted on the mounting member 12. The belt-shifting mechanism 30 is mounted on the mounting member 12, and the movable mounting component 22 is drivably connected to the belt-shifting mechanism 30, which drives the movable mounting component 22 to move closer to or away from the static mounting component 21. A chain is detachably wound around the static mounting component 21 and the movable mounting component 22. The measuring mechanism 40 is installed on the mounting member 12 and is used to measure the distance that the moving mounting member 22 moves away from the stationary mounting member 21 under the constraint of the chain by the belt shifting mechanism 30, thereby measuring the center distance of the chain.

[0026] Understandably, after the chain is wound around the periphery of the stationary mounting component 21 and the moving mounting component 22, the belt shifting mechanism 30 drives the moving mounting component 22 to move away from the stationary mounting component 21 until the chain is taut. At this point, the chain prevents the moving mounting component 22 from moving further, and then the measuring mechanism 40 measures the center distance of the chain.

[0027] It is worth mentioning that, in the vertical direction, the projected area of ​​the mounting component 12 on the horizontal plane is smaller than the projected area of ​​the mounting component 12 on the horizontal plane when it is placed horizontally. In other words, compared with the prior art, this application utilizes vertical space, thereby reducing the horizontal footprint of the device itself, so that the chain center distance detection device can be directly placed on a narrow workbench for use.

[0028] Specifically, the static mounting component 21 includes a static mounting base 211 and a first gear 212. The first gear 212 is mounted on the static mounting base 211. The static mounting base 211 is fixedly mounted on the mounting member 12, and the chain is detachably engaged with the first gear 212.

[0029] The movable mounting component 22 includes a movable mounting base 221 and a second gear 222. The second gear 222 is mounted on the movable mounting base 221, which is slidably mounted on the mounting member 12 and is drivably connected to the belt conveyor 30. The chain is detachably engaged with the second gear 222.

[0030] In a preferred embodiment, the first gear 212 is rotatably mounted on the stationary mounting base 211 so that when the chain is straightened, some of the sliding friction is converted into rolling friction, thereby reducing damage to the chain.

[0031] Also preferably, the second gear 222 is rotatably mounted on the moving mounting base 221 so that when the chain is straightened, some of the sliding friction is converted into rolling friction, thereby reducing damage to the chain.

[0032] In one embodiment, the axis of the first gear 212 and the axis of the second gear 222 are at the same horizontal height, and the movable mounting base 221 is driven by the belt-moving mechanism 30 to move in the horizontal direction.

[0033] Preferably, the mounting component 12 is perpendicularly connected to the support component 11. In the initial state, the straight-line distance between the axis of the first gear 212 and the axis of the second gear 222 is less than the center distance of the chain. The inspector can suspend the chain between the first gear 212 and the second gear 222 to complete the assembly of the chain and the bearing mechanism 20. This is simple, convenient and quick, shortens the assembly time, and thus improves the inspection efficiency.

[0034] In another embodiment, either the movable mounting member 22 or the static mounting member 21 is mounted on the high end portion 121, and the other is mounted on the low end portion 122. In this way, the movable mounting member 22 is driven by the conveyor mechanism 30 to move at least vertically.

[0035] The inspector suspends the chain from the first gear 212 or the second gear 222 mounted on the high end 121. Under the influence of gravity, the bottom of the chain naturally droops and aligns with the position of the low end 122. The inspector then completes the assembly by adjusting the position of the second gear 222 or the first gear 212 mounted on the low end 122 and the bottom of the chain. This eliminates the need for the inspector to constantly tighten and hold the chain during assembly, thus shortening the assembly time between the chain and the supporting mechanism 20 and improving inspection efficiency.

[0036] In one example, the mounting member 12 is mounted at an angle to the support member 11, and the mounting member 12 and the support member 11 form a triangular structure to improve the stability of the device body 10.

[0037] Preferably, the mounting member 12 forms a limiting structure 123, and the movable mounting base 221 is slidably mounted on the limiting structure 123. The limiting structure 123 is used to limit the movement of the movable mounting base 221 toward or away from the stationary mounting base 211.

[0038] As an example, the limiting structure 123 is implemented as a guide rail or optical axis.

[0039] In one embodiment, the conveyor mechanism 30 is implemented including a cylinder.

[0040] In another embodiment, the conveyor mechanism 30 includes a lead screw 31, and the movable mounting base 221 forms a threaded hole 22101. The lead screw 31 is threaded into the threaded hole 22101 formed by the movable mounting base 221. The movable mounting base 221 is restricted by the limiting structure 123 to move along the axial direction of the lead screw 31 toward or away from the stationary mounting base 211.

[0041] In one example, the conveyor mechanism 30 further includes a motor, to which the lead screw 31 is rotatably connected, and the motor drives the lead screw 31 to rotate.

[0042] In another example, the belt shifting mechanism 30 further includes a handwheel 32, which is mounted at one end of the lead screw 31 to provide a point for the inspector to rotate the belt shifting mechanism 30. The radial dimension of the handwheel 32 is larger than that of the lead screw 31 to facilitate the application of force by the inspector. Since this example is manually operated and requires no drive, the chain center distance detection device has low manufacturing cost, light weight, is easy to transport, and has few limitations in use.

[0043] In one example, the measuring mechanism 40 is implemented as a dial indicator located on the moving path of the movable mounting component 22 away from the stationary mounting component 21 to detect the maximum travel distance of the movable mounting component 22 under the constraint of the chain.

[0044] It is worth mentioning that the chain center distance detection device also includes at least one pair of anti-shift posts 50, which are installed on the mounting member 12. The two anti-shift posts 50 in each pair are distributed on both sides of the movable mounting base 221 and are respectively located on the moving path of the movable mounting base 221 toward and away from the stationary mounting base 211, so as to limit the range of movement of the movable mounting base 221.

[0045] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
