Description

Technical Field

[0001] This application relates to the technical field of jigs, and in particular to a synchronous belt multi-tooth-shaped jig. Background Art

[0002] Synchronous belts, also known as toothed belts, timing belts, non-slip belts, etc. Similar to common belt drive methods such as ordinary V-belts and flat belts, synchronous belts are a form of flexible drive. Synchronous belts can not only be used to transmit motion and power, but are also commonly used in servo mechanisms for positioning of mechanisms.

[0003] During the production process of synchronous belts, tests (such as tensile tests) need to be carried out to ensure that their performance meets the usage requirements. During the test process, the role of the jig is crucial. It needs to firmly clamp the synchronous belt to ensure the accuracy and repeatability of the test. However, the existing synchronous belt jigs are relatively single, and they can only clamp synchronous belts of a single specification, which has limitations. Therefore, a synchronous belt multi-tooth-shaped jig is proposed to solve the above technical problems. Utility Model Content

[0021] Next, in combination with the specific embodiments, the present application will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that for the orientation terms, if there are terms such as "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation and position relationship is based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0024] One of the preferred embodiments of the present application is as Figures 1 to 5 shown. A synchronous belt multi-tooth fixture includes a mounting rack 1, a limiting device 3, and an adjusting device 4. Among them, the limiting device 3 and the adjusting device 4 are both installed in the mounting rack 1, and a clamping area is formed between the limiting device 3 and the adjusting device 4. The synchronous belt can be clamped and fixed through the clamping area.

[0025] It can be understood that before clamping, we first adjust the clamping area according to the specification size of the synchronous belt, and the adjusting device 4 can adjust the clamping area to adapt to synchronous belts of different specifications; that is to say, the fixture in the present application can be adaptively adjusted according to synchronous belts of different specification sizes, thereby greatly improving its flexibility in use.

[0026] In one of the embodiments of the present application, as Figure 2As shown in the figure, the adjusting device 4 includes an adjusting wheel 401 and a positioning component 402. The adjusting wheel 401 is rotatably installed in the mounting bracket 1, and multiple tooth-shaped areas with different specifications are provided on the adjusting wheel 401. Specifically, for example, the sizes and spacings of the teeth between different tooth-shaped areas are different, and each specification of the tooth-shaped area corresponds to a synchronous belt of the corresponding specification. The limiting device 3 and the corresponding tooth-shaped area cooperate to form a clamping area for limiting the synchronous belt.

[0027] Specifically, for example, when clamping the synchronous belt, we attach one (toothed) end of the synchronous belt to the corresponding tooth-shaped area, and then through the cooperation of the limiting device 3, one end of the synchronous belt can be clamped and fixed between the limiting device 3 and the tooth-shaped area.

[0028] Of course, the present application does not specifically limit the structural form of the positioning component 402. The following provides a specific embodiment for illustration:

[0029] As Figure 4 shown in the figure, the positioning component 402 includes a positioning rod 4021 and multiple positioning grooves 4022. The positioning grooves 4022 are provided on the adjusting wheel 401, and the positioning rod 4021 is slidably arranged on the mounting bracket 1. Of course, the number of the positioning grooves 4022 corresponds to the number of the corresponding tooth-shaped areas.

[0030] It can be understood that when we need to adjust the tooth-shaped area, we can rotate the adjusting wheel 401 to make the corresponding tooth-shaped area rotate to correspond to the limiting device 3, and then the adjusting wheel 401 can be locked: we insert the positioning rod 4021 into the mounting bracket 1 so that the positioning rod 4021 is inserted and matched with the corresponding positioning groove 4022. At this time, the rotation of the adjusting wheel 401 can be restricted, and thus the adjusting wheel 401 can be locked.

[0031] On the contrary, when we need to rotate and adjust the adjusting wheel 401, at this time, we can pull out (move in the reverse direction) the positioning rod 4021 to disengage the positioning rod 4021 from the positioning groove 4022, and then the locking of the adjusting wheel 401 can be released, and the adjusting wheel 401 can be rotated and adjusted.

[0032] In one embodiment of the present application, as Figure 3 shown in the figure, the limiting device 3 includes a limiting rod 301. The limiting rod 301 is in threaded cooperation with the mounting bracket 1 and corresponds to the adjusting wheel 401.

[0033] It can be understood that when clamping the synchronous belt, it should be known that since the toothed side of the synchronous belt is attached to the tooth-shaped area of the adjusting wheel 401, at this time, only by turning the limit rod 301 forward, the limit rod 301 will rotate and advance spirally along the mounting frame 1, and then the end of the limit rod 301 will abut against the toothless side of the synchronous belt, so that the synchronous belt can be limited and fixed and locked between the limit rod 301 and the adjusting wheel 401.

[0034] Furthermore, since the contact area between the end of the limit rod 301 and the synchronous belt is small, the clamping effect will be poor during clamping. At the same time, since the limit rod 301 rotates and advances spirally and cooperates with the synchronous belt, it may also cause damage to the synchronous belt.

[0035] Therefore, to solve the above technical problems, in one embodiment of the present application, as Figure 1 and Figure 2 shown, the limiting device 3 further includes a baffle 304, and the baffle 304 is movably arranged on the mounting frame 1 and located in the clamping area; specifically, a pin shaft can be provided at the upper end position of the baffle 304, a strip-shaped groove is provided at the upper end position of the mounting frame 1, and the pin shaft cooperates with the strip-shaped groove, and the pin shaft can be adjusted arbitrarily in the up, down, left and right directions within a certain range of the strip-shaped groove.

[0036] It can be understood that when clamping the synchronous belt at this time, the synchronous belt is located between the baffle 304 and the adjusting wheel 401, and then the limit rod 301 is turned, so that the limit rod 301 clamps and fixes the synchronous belt through the baffle 304, which can greatly improve the clamping effect on the synchronous belt.

[0037] However, in actual use, there may still be such problems: for example, when clamping the synchronous belt and performing a tensile test, we know that the synchronous belt itself is made of a flexible material, so when being stretched, its end will become longer and thinner as the tensile force increases, and then it may suddenly "break away from the clamping" state, that is, at this time the synchronous belt will suddenly break away, and the originally stretched synchronous belt has a large tension, which may pose a safety risk to the operator.

[0038] To solve the above problems, in another embodiment of the present application, as Figure 2 and Figure 3 shown, the limiting device 3 further includes a roller 303, the roller 303 is rotatably installed on the (U-shaped) bracket 302, the bracket 302 is horizontally slidably installed on the mounting frame 1, and at this time the positions of the roller 303 and the end of the limit rod 301 correspond to each other, and the limit rod 301 penetrates through the bracket 302.

[0039] Specifically, the limit rod 301 is actually a bolt, and when the synchronous belt is clamped and fixed, the bolt is screwed, and when the bolt moves, the screw head part will drive the bracket 302 to move synchronously, thereby making the roller 303 press against the baffle 304, that is, at this time, the roller 303 and the baffle 304 cooperate to realize the squeezing effect on the synchronous belt.

[0040] When clamping, the baffle 304 is at the highest position, so the baffle 304 will maintain this height under the clamping force; when the synchronous belt is stretched, if the tension is too large, the synchronous belt will become thinner and tend to escape from the clamp. At this time, since the baffle 304 and the roller 303 are in rolling cooperation, the friction will be very small, and the baffle 304 will move down one end of the synchronous belt synchronously, which will reduce the deformation and tension of the synchronous belt. When it is subsequently separated, the force of the synchronous belt will be greatly reduced, further improving safety.

[0041] In one of the embodiments of the present application, Figure 1 As shown, the mounting frame 1 includes a pair of mounting plates 101, and the two mounting plates 101 are detachably mounted through mounting blocks, thereby forming a stable frame structure. Through such a detachable structure, it can be convenient for the later repair and maintenance of the clamp, and it can also be quickly adjusted and replaced according to different usage requirements. For example, the adjusting wheel 401 can be quickly replaced. We know that the number of toothed areas set on the adjusting wheel 401 is limited, so the number of corresponding synchronous belt specifications is also limited, so that it can be suitable for clamping and fixing more synchronous belts.

[0042] Further, such as Figure 1 As shown, a hoisting rod 2 is detachably mounted on the top of the mounting frame 1 by bolts, and the hoisting rod 2 can be conveniently connected to the tensile testing machine, thereby realizing the automated operation of the tensile test of the synchronous belt. The design of the hoisting rod 2 not only improves the convenience of operation, but also significantly improves the work efficiency when conducting large-scale tests.

[0043] The working principle of the utility model is:

[0044] We take the synchronous belt tensile test as an example to illustrate. First, we connect the two clamps to the tensile testing machine through the lifting rod 2, and then match the two ends of the synchronous belt with the corresponding clamps respectively. Specifically: first rotate the adjusting wheel 401 to make the corresponding toothed area rotate to correspond to the baffle 304, then insert the positioning rod 4021 into the corresponding positioning groove 4022, and then lock the adjusting wheel 401, and then fit the toothed side of the synchronous belt on the adjusted toothed area, as shown in FIG. Figure 5As shown, turn the limit rod 301 (bolt). While the bolt moves, the head part of the bolt will drive the bracket 302 to move synchronously, so that the roller 303 abuts and presses against the baffle 304. Finally, the clamping and fixing of the synchronous belt can be realized through the extrusion cooperation between the baffle 304 and the adjusting wheel 401, and then the tensile test of the synchronous belt can be carried out.
