The two guide posts are slidably connected to the two guide grooves respectively. Each guide groove is bent away from the push-pull bar along the y-axis direction. The guide groove is used to drive the other end of the gripper to rotate away from the push-pull bar along the y-axis direction, so that the other end of the gripper drives the chain product to be clamped.

[0009] In this embodiment, the other end of the gripper is provided with an anti-slip positioning post.

[0010] In this embodiment, the z-axis rotation module includes a break-in motor, a first rotating shaft, a second rotating shaft, and a third rotating shaft. The first rotating shaft is connected to the break-in motor, which is located above the break-in oil tank. A first bevel gear is provided at the bottom end of the first rotating shaft.

The first bevel gear meshes with the second bevel gear, and the third bevel gear meshes with the fourth bevel gear. The first rotating shaft and the third rotating shaft are both parallel to the z-axis, and the second rotating shaft is parallel to the x-axis.

[0011] In this embodiment, the tensioning x-axis translation module includes a tensioning motor, a drive gear, a transmission chain, a guide rod, and several tensioning gears. The tensioning motor is located above the break-in oil tank. The drive gear is connected to the tensioning motor. The guide rod is connected inside the break-in oil tank.

[0017] By setting up a transfer assembly to move the chain product between the external conveyor belt and the break-in assembly, the movement between each component is smooth and coordinated, reducing direct manual intervention. This not only effectively improves break-in efficiency but also ensures good safety and low labor costs. Two sets of transfer x-axis translation modules and clamping modules work together to clamp the chain product, ensuring accurate and reliable clamping and positioning. The transfer yz-axis positioning module positions the clamping structure along the yz axis, providing flexible positioning and enabling stable and reliable transfer of the chain product between the chain product and the break-in oil tank. This provides stable and accurate positioning conditions for the subsequent break-in process. By tightening the x-axis translation module… The moving module drives two tensioning translation blocks to move in opposite directions, allowing the two running wheels to take over the chain product from the two clamping modules and achieve tension. This effectively ensures the contact effect between the running wheels and the chain product, thus providing reliable processing conditions for subsequent running-in. The Z-axis rotation module drives at least one running wheel to rotate, effectively causing the chain product to rotate around the two running wheels, thereby performing a smooth running-in process on the teeth of the chain product. The running-in process is comprehensive and reliable, effectively improving the structural reliability of each tooth of the chain product. The running wheels, in conjunction with the immersed running-in oil tank, can achieve reliable running-in processing on the chain product, with good running-in effect, effectively extending the service life of the chain product.

[0034] In the field of mechanical transmission, chains are widely used as an important transmission component in various mechanical equipment. Chains are mainly composed of a series of interconnected links, which transmit force or motion between two or more objects through the connection and cooperation of the links. The timing chain of an automobile engine is a type of chain and an important component of the engine's valve train system. After a new chain is assembled, its surface usually has some unavoidable defects such as burrs. To ensure product quality and performance, grinding operations are usually required before the chain leaves the factory to improve its smoothness. In related technologies, the outer surface of the chain is ground manually by hand using a mechanically driven grinding block. This grinding method has a limited range of effects, is not ideal, makes it difficult to guarantee uniformity and consistency, has low processing efficiency, and poses significant safety hazards.

[0035] With the rapid development of automation technology, more and more companies are exploring the use of automated equipment for chain break-in. However, most existing automated break-in equipment suffers from problems such as complex structure, cumbersome operation, and poor break-in results. In particular, how to achieve precise chain positioning, stable clamping, and uniform break-in during the chain clamping, positioning, and break-in process remains a pressing technical challenge that needs to be addressed.

[0036] The following is for reference only. Figure 1 To be continued Figure 6 This invention describes a smooth break-in device for automotive engine timing chains, which has high processing efficiency, good safety performance, comprehensive and reliable break-in, and good break-in effect.

[0037] Reference Figures 1 to 6A smooth break-in device for a timing chain of an automotive engine according to an embodiment of this utility model includes:

[0038] The transfer assembly 100 includes a transfer positioning frame 110, a transfer yz-axis positioning module 120, and a transfer clamping structure. The transfer yz-axis positioning module 120 is connected to the transfer positioning frame 110. The transfer clamping structure includes two transfer x-axis translation modules 130 and two clamping modules 140. The drive trajectories of the two transfer x-axis translation modules 130 in the same transfer clamping structure are collinear. The two clamping modules 140 are respectively connected to the two transfer x-axis translation modules 130. The two transfer x-axis translation modules 130 are used to drive the two clamping modules 140 to move towards or away from each other along the x-axis. The clamping modules 140 are used to clamp the chain product along the y-axis direction. The chain product can be a timing chain of an automobile engine. The transfer x-axis translation module 130 can be a drive mechanism such as an electric cylinder or a pneumatic cylinder that can drive translation in the x-axis direction.

[0039] The break-in assembly 200 includes a break-in oil tank 210, a tensioning x-axis translation module 220, a z-axis rotation module 230, and two tensioning translation blocks 240. The break-in oil tank 210 is located within the drive positioning trajectory projection of the transfer yz-axis positioning module 120. The break-in oil tank 210 is connected below the transfer positioning frame 110. The transfer yz-axis positioning module 120 is used to drive the transfer clamping structure to pick up and place the chain product in the break-in oil tank 210. The break-in oil tank 210 stores lubricating oil for polishing. Both tensioning translation blocks 240 are slidably connected within the break-in oil tank 210. Both are connected to the tensioning x-axis translation module 220. The tensioning x-axis translation module 220 is used to drive two tensioning translation blocks 240 to move towards or away from each other along the x-axis. Each tensioning translation block 240 is rotatably connected to a break-in wheel 250. The break-in wheel 250 is rotatably connected to the tensioning translation block 240 through a bearing so that the break-in wheel 250 can rotate relative to the tensioning translation block 240 around the z-axis. At least one break-in wheel 250 is connected to the z-axis rotation module 230. The z-axis rotation module 230 is used to drive at least one break-in wheel 250 to rotate around the z-axis. The break-in wheel 250 is used to wind and polish the chain product.

[0040] During operation, the YZ-axis positioning module 120 drives the transfer clamping structure to the external conveyor belt. Two X-axis translation modules 130 drive two clamping modules 140 to move in opposite directions, clamping and positioning the chain product on the external conveyor belt. The YZ-axis positioning module 120 drives the transfer clamping structure to the break-in oil tank 210, where the chain product is immersed in the lubricating oil. The two clamping modules 140 are located on either side of the two break-in wheels 250. The x-axis translation module 220 drives two tensioning translation blocks 240 to move in opposite directions along the x-axis until the two running wheels 250 are engaged on opposite sides of the chain product. After the two clamping modules 140 release the chain product, the transfer yz-axis positioning module 120 drives the transfer clamping structure to reset. The z-axis rotation module 230 drives at least one running wheel 250 to rotate, thereby driving the chain product to rotate. The running wheel 250, in conjunction with lubricating oil, performs a running-in process on the chain product, which can effectively improve the smoothness of the chain product.

[0041] By setting up a transfer component to transfer the chain product between the external conveyor belt and the break-in component 200, the movement between the components is smooth and coordinated, reducing direct manual intervention. This not only effectively improves the break-in process efficiency but also ensures good safety and low labor costs. The transfer clamping structure uses two sets of transfer x-axis translation modules 130 and clamping modules 140 to clamp the chain product in a coordinated manner. The clamping and positioning action is accurate and reliable. The transfer yz-axis positioning module 120 positions the transfer clamping structure in the yz-axis direction, providing flexible positioning. This enables the chain product to be picked up and transferred between the break-in oil tank 210. The pick-up and transfer action is stable and reliable, providing stable and accurate positioning conditions for the subsequent break-in process. By driving two tensioning translation blocks 240 to move in opposite directions through the tensioning x-axis translation module 220, the two break-in wheels 250 are moved from... Two clamping modules 140 receive the chain product and tighten it, effectively ensuring the contact between the break-in wheel 250 and the chain product, thus providing reliable processing conditions for subsequent break-in. The Z-axis rotation module 230 drives at least one break-in wheel 250 to rotate, effectively causing the chain product to rotate around the two break-in wheels 250, thereby performing a smooth break-in process on the teeth of the chain product. The break-in process is comprehensive and reliable, effectively improving the structural reliability of each tooth of the chain product. The break-in wheel 250, in conjunction with the immersion break-in oil tank 210, enables reliable break-in processing of the chain product. The lubricating oil in the break-in oil tank 210 not only effectively reduces the frictional resistance generated during the break-in process and effectively reduces the wear of the chain product, but also plays a role in lubrication and cooling. The break-in effect is good, which can effectively extend the service life of the chain product.

[0042] It should be noted that the transfer yz axis positioning module 120 can be configured as a gantry module for realizing yz axis positioning. Specifically, it can be composed of two linear modules connected in two dimensions of yz axis. The transfer yz axis positioning module 120 can also be a combination of other drive mechanisms that can realize yz axis positioning.

[0043] It is understood that the clamping module 140 includes a transfer x-axis translation plate 150, a clamping drive mechanism 160, a push-pull bar 170, and two grippers 180. The transfer x-axis translation plate 150 is connected to the transfer x-axis translation module 130, the clamping drive mechanism 160 is connected to the transfer x-axis translation plate 150, and the push-pull bar 170 is connected to the clamping drive mechanism 160. The clamping drive mechanism 160 is used to drive the push-pull bar 170 to translate along the x-axis direction. The push-pull bar 170 is parallel to the x-axis. The transfer x-axis translation plate 150 is provided with two guide grooves 151 located on both sides of the push-pull bar 170. The guide groove 151 is symmetrical about the push-pull bar 170. One end of each gripper 180 is rotatably connected to the push-pull bar 170. Each gripper 180 has a guide post 181 in the middle. Two guide posts 181 are slidably connected in two guide grooves 151. Each guide groove 151 is bent away from the push-pull bar 170 along the y-axis. The guide groove 151 is used to drive the other end of the gripper 180 to rotate away from the push-pull bar 170 along the y-axis, so that the other end of the gripper 180 drives the chain product to be clamped and tightened. The clamping drive mechanism 160 can be an electric cylinder or a pneumatic cylinder.

[0044] By clamping the chain product by opening the gripper 180 in the y-axis direction, it can make way for the tensioning of the break-in wheel 250, which can effectively improve the continuity and reliability of the overall equipment operation.

[0045] Understandably, the other end of the gripper 180 is provided with an anti-slip positioning post 182. The anti-slip positioning post 182 is used to straighten the chain product outward. The surface of the anti-slip positioning post 182 is formed with an anti-slip layer, which can effectively improve the positioning effect of the chain product.

[0046] It is understood that the z-axis rotation module 230 includes a break-in motor 231, a first rotating shaft 232, a second rotating shaft 233, and a third rotating shaft 234. The top of the first rotating shaft 232 is connected to the break-in motor 231, which drives the first rotating shaft 232 to rotate. The break-in motor 231 is located above the break-in oil tank 210, ensuring the reliability of its structure. The bottom of the first rotating shaft 232 is provided with a coaxial first bevel gear 235. The second rotating shaft 233 is rotatably connected to the break-in oil tank 210. The two ends of the second rotating shaft 233 are respectively provided with a second bevel gear 236 and a third bevel gear 237. The bottom of the third rotating shaft 234 is provided with a fourth bevel gear 238. The break-in wheel 250 is connected to the third rotating shaft 234. At the top of the rotating shaft 234, the third rotating shaft 234 is connected to the tensioning translation block 240 via a bearing. The first bevel gear 235, the second bevel gear 236, the second rotating shaft 233, the third bevel gear 237, and the fourth bevel gear 238 are all located in the break-in oil tank 210. The first bevel gear 235 is meshed with the second bevel gear 236, and the third bevel gear 237 is meshed with the fourth bevel gear 238. The first rotating shaft 232 and the third rotating shaft 234 are both parallel to the z-axis, and the second rotating shaft 233 is parallel to the x-axis. The break-in motor 231 drives the break-in wheel 250 to rotate by setting multiple rotating shafts and bevel gears. This can effectively separate the break-in motor 231 from the outside of the break-in oil tank 210, which can effectively improve the reliability of the overall structure.

[0047] It is understood that the tensioning x-axis translation module 220 includes a tensioning motor 221, a drive gear 222, a transmission chain 223, a guide rod 224, and several tensioning gears 225. The tensioning motor 221 is located above the break-in oil tank 210. The drive gear 222 is connected to the tensioning motor 221. The guide rod 224 is parallel to the x-axis and connected inside the break-in oil tank 210. The tensioning translation block 240 is slidably connected to the guide rod 224 via a linear bearing. Each tensioning gear 225... 25 is rotatably connected to the break-in oil tank 210. The transmission chain 223 is wound around the drive gear 222 and each tensioning gear 225. A positioning rack 260 is provided on one side of the tensioning translation block 240. The positioning rack 260 is meshed with the transmission chain 223. The tensioning motor 221 drives the transmission chain 223 to rotate through the drive gear 222, thereby driving the positioning rack 260 to move. Under the limiting action of the guide rod 224, the tensioning translation block 240 translates along the x-axis.

[0048] Specifically, in the same set of tensioned x-axis translation modules 220, one positioning rack 260 is connected to the side of one tensioned translation block 240 in the positive y-axis region, and the other positioning rack 260 is connected to the side of another tensioned translation block 240 in the negative y-axis region, so that the two positioning racks 260 respectively mesh with the opposite sides of the transmission chain 223, thereby driving the two positioning racks 260 to move towards or away from each other.

[0049] Understandably, the break-in oil tank 210 is hinged with a cover 211, and the break-in assembly 200 also includes a flip-top Z-axis lifting module 270. A connecting rod 212 is located at the bottom of the cover 211, and the two ends of the connecting rod 212 are rotatably connected to the cover 211 and the flip-top Z-axis lifting module 270, respectively. The flip-top Z-axis lifting module 270 drives the connecting rod 212 to descend, thereby closing the cover 211 at the opening of the break-in oil tank 210. This effectively improves the reliability of the break-in process and extends the service life of the lubricating oil in the break-in oil tank 210. Preferably, the flip-top Z-axis lifting module 270 can be a linear drive mechanism such as an electric cylinder or pneumatic cylinder that outputs along the Z-axis.

[0050] Understandably, the smooth break-in equipment for automotive engine timing chains also includes a machine base 300, which has a conveyor station 310 for setting up an external conveyor belt. There are two transfer clamping structures and four sets of break-in components 200. The four sets of break-in components 200 are evenly distributed on opposite sides of the conveyor station 310, that is, there are two sets of break-in components 200 on each opposite side of the conveyor station 310, which can effectively improve the break-in process efficiency.

[0051] Understandably, the smooth break-in equipment for the timing chain of an automotive engine also includes an oil circulation assembly 400. The oil circulation assembly 400 includes a circulating oil tank 410 and an oil pump 420. The oil pump 420 connects the circulating oil tank 410 and the break-in oil tank 210. The oil pump 420 is used to circulate the lubricating oil in the break-in oil tank 210 and the circulating oil tank 410. The oil circulation assembly 400 can replenish the lubricating oil online, which can effectively ensure the break-in effect.

[0052] Understandably, the oil circulation assembly 400 also includes an iron powder separator 430, which is located in the circulating oil tank 410. The iron powder separator 430 is used to separate the iron powder particles formed during the break-in process from the lubricating oil in the circulating oil tank 410, which can effectively improve the performance of the lubricating oil and thus improve the break-in effect.

[0053] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
