Description

Technical Field

[0001] This utility model relates to the technical field of chain processing equipment, specifically a fastening device for chain processing. Background Technology

[0002] Chains are an important mechanical transmission device, mainly used for transmitting power, conveying materials, pulling, and lifting. After the chain is processed, the outside of the chain needs to be tightened to make the external fit of the chain more stable.

[0003] For example, the utility model patent disclosed in publication number CN218310679U discloses an automatic tightening device for chain processing, including a base chamber. The left and right inner walls of the base chamber are respectively movably mounted with the two ends of a threaded rod via bearings. A movable block is movably mounted on the outer peripheral wall of the threaded rod. An L-shaped plate is fixedly mounted on the top surface of the base chamber near the right side. A pressing component is provided at the bottom of the L-shaped plate. A support frame is fixedly mounted on the top surface of the base chamber. A motor is fixedly mounted on the inner bottom wall of the base chamber. One end of a worm gear is fixedly mounted on the output shaft of the motor. The other end of the worm gear is movably mounted to the front inner wall of the base chamber via a bearing. A worm wheel is fixedly fitted on the outer peripheral wall of the threaded rod. A liquid tank is fixedly mounted on the top surface of the support frame. A lubrication component is provided at the bottom of the support frame. This automatic tightening device for chain processing allows lubricating oil to drip onto the chain through a liquid outlet pipe via the lubrication component, thereby facilitating chain processing and improving the overall practicality of the device.

[0004] Although the aforementioned equipment can perform chain tightening and lubrication operations, it lacks stability in gradually tightening the chain and also suffers from insufficient uniformity in lubricating the chain's exterior, thus reducing the efficiency of chain processing. Therefore, there is an urgent need for a chain tightening device to solve these problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides an embodiment of a chain processing fastening device, comprising a support base 3 with a support guide 1 on its top, a servo motor 6 fixedly mounted at the center of the rear end face of the support guide 1, a transmission screw 8 mounted at the output end of the servo motor 6, a threaded guide 7 slidably connected to the inner end face of the support guide 1, and a guide fixture 5 mounted on the lower end face of the threaded guide 7.

[0025] The oil spraying device 2 has two sets, and the two sets of oil spraying devices 2 are respectively fixedly installed at the front and rear of the inner end of the support base 3. The oil spraying device 2 is used to lubricate the chain.

[0026] The fastening device 4 is fixedly installed at the center of the upper end face of the support base 3. The fastening device 4 is used to fasten the chain.

[0027] The oil injection device 2 includes an oil storage tank 25. Five sets of liquid guide pumps 22 are equidistantly arranged on the inner end face of the oil storage tank 25. An inlet 23 is opened on the side end face of the liquid guide pump 22 near the bottom. An oil nozzle 24 is arranged on the top of the liquid guide pump 22. Two sets of protective baffles 21 are arranged on the upper end face of the oil storage tank 25.

[0028] The clamping device 4 includes a limiting seat 42. A reduction motor 43 is provided at the center of the rear end face of the limiting seat 42, and a bidirectional lead screw 44 is provided at the output end of the reduction motor 43. Two sets of ball slides 41 are threadedly connected to the inner end face of the limiting seat 42 through the bidirectional lead screw 44, and a clamping clamp 45 is provided on the upper part of the ball slides 41.

[0029] The guide fixture 5 is adapted to the transmission screw 8 through the threaded guide seat 7 and then threadedly connected to the inner end face of the support guide seat 1, which can effectively improve the accuracy and stability of subsequent equipment in guiding the chain to tighten.

[0030] The lower end face of the guide fixture 5 is aligned with the central axis of the support base 3 along its length, which can effectively improve the accuracy of subsequent lubrication application to the outside of the chain.

[0032] Working principle: Before tightening the chain, the operator can introduce lubricating oil into the oil tank 25. Simultaneously, the operator can position the chain to be tightened at the bottom of the guide fixture 5, facilitating continuous traction of the chain for tightening. During tightening, the servo motor 6 drives the transmission screw 8 to rotate. The transmission screw 8, in turn, drives the threaded guide seat 7, intermittently displacing the guide fixture 5 on the upper part of the tightening device 4. The front part is the tightening position. The chain can pass through the centerline of the two sets of protective baffles 21. At this time, multiple sets of liquid pumps 22 can draw oil from the inside of the oil storage tank 25 through the liquid inlet 23, and then spray it evenly on the outside of the chain through the oil nozzle 24. When tightening, the reduction motor 43 starts. The reduction motor 43 can drive the two sets of ball slides 41 to move centripetally through the bidirectional lead screw 44, so that the ball slides 41 can drive the two sets of tightening clamps 45 to tighten the chain located in the middle, and repeat the cycle.
