Description

Technical Field

[0001] The utility model relates to the technical field of torque limiter production, in particular to a torque limiter polishing machine with a positioning function. Background Art

[0002] The safety coupling (also called torque limiter, torque limiter, safety clutch) is a component that connects the driving machine and the working machine. Its main function is overload protection. When the required torque exceeds the set value due to overload or mechanical failure, the torque limiter limits the torque transmitted by the transmission system in the form of slipping. When the overload disappears, it automatically restores the connection, thus preventing mechanical damage and avoiding expensive downtime losses.

[0003] For example, the application number is CN202223383945.5. The utility model belongs to the technical field of torque limiters, and is particularly a torque limiter, comprising a pulley, a pressure plate, a hub and a spring support frame, and also comprising bolts, telescopic springs, nuts, needle bearings and friction plates; a plurality of the bolts are equally spaced along the circumferential direction, and the telescopic springs are sleeved on the bolts and are located between the bottom surface of the pressure plate and the spring support frame; the torque limiter of the utility model improves the resistance of the overall structure to radial force by arranging needle bearings, can withstand large radial loads, and greatly improves the rotational speed of its structure, so the torque limiter is also suitable for high-speed use scenarios; a structural form of multiple telescopic springs is adopted, and the tension of the telescopic springs can be adjusted by rotating the nut to achieve the adjustment of the output torque, which is convenient to adjust and can provide a certain amount of automatic compensation when the friction plate is slightly worn, thereby maintaining the stability of the output torque.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem of a bushing between the pressure block and the output shaft of the reducer, in actual operation, there will be severe friction between the chain plate and the outer cylindrical surface of the bushing, which will cause the bushing to be worn thin in a relatively short period of time, and then the chain plate will move radially, resulting in damage to the entire torque limiter. However, during use, the user usually uses a polishing machine to polish the surface of the torque limiter, and the user is often required to hold the torque limiter in hand for polishing during the polishing process, which can easily lead to the torque limiter being knocked away due to unstable handholding during the polishing process.

A positioning rod 64 is provided at the bottom of the front side of the movable cylinder 61, and the back side of the positioning rod 64 extends to the back side of the movable cylinder 61 through the positioning grooves 63.

[0024] As a technical optimization scheme of the utility model, by setting a height adjustment mechanism 6, if the height of the torque limiter housing 3 is not enough or too high, the user can directly take out the positioning rod 64 from the positioning groove 63, and then the user can directly move the movable rod 62 inside the movable cylinder 61 to adjust the height, and then the movable rod 62 drives the torque limiter housing 3 to adjust the height. After the adjustment is completed, the user can insert the positioning rod 64 into the positioning groove 63 and insert it to the back of the movable cylinder 61 through the positioning groove 63, thereby positioning the movable rod 62.

[0033] refer to Figures 1 to 3 A knob 15 is fixedly connected to the top of the screw rod 9, and the knob 15 is arranged in a cross shape.

[0034] As a technical optimization solution of the utility model, by setting the knob 15, when the user needs to rotate the screw 9, the user can apply force by buckling the cross-shaped knob 15, and then the knob 15 drives the screw 9 to rotate, providing the user with a point for applying force.

[0035] The working principle and use process of the utility model are as follows: when the user needs to polish the torque limiter housing 3, the user places the torque limiter housing 3 between the positioning ring 8 and the fixing ring 7, and then the user can rotate the screw rod 9 to rotate the screw rod 9 to drive the positioning ring 8 to move downward, and during the rotation of the screw rod 9, the limiting rod 101 and the limiting groove 102 are used to slide and cooperate, so as to limit the rotation of the positioning ring 8, so as to prevent the positioning ring 8 from rotating but unable to move up and down during the transmission of the screw rod 9, and then after the positioning ring 8 moves downward, the torque limiter housing 3 can be positioned, and then the user can push the slider 5 moves to the right side to approach the polishing machine body 2, and opens the polishing machine body 2 to polish the torque limiter housing 3. If the height of the torque limiter housing 3 is not enough or too high, the user can directly take out the positioning rod 64 from the positioning groove 63, and then the user can directly move the movable rod 62 inside the movable cylinder 61 to adjust the height, and then the movable rod 62 drives the torque limiter housing 3 to adjust the height. After the adjustment is completed, the user can insert the positioning rod 64 into the positioning groove 63 and insert it to the back of the movable cylinder 61 through the positioning groove 63, so as to position the movable rod 62, and have the ability to position the torque limiter housing 3.

[0036] To sum up: the torque limiter polishing machine with a positioning function, by setting a positioning ring 8, places the torque limiter housing 3 between the positioning ring 8 and the fixing ring 7, and then the user can drive the positioning ring 8 to move downward by rotating the screw 9 to position the torque limiter housing 3, thereby solving the problem that users usually use polishing machines to polish the surface of the torque limiter, and during the polishing process, the user often needs to hold the torque limiter for polishing, which easily leads to the problem of the torque limiter being knocked away due to unstable handholding during the polishing process.
