Description
A piston pin machining oil injection device Technical Field
[0001] This utility model relates to the field of piston pin processing technology, specifically to a piston pin processing oil injection device. Background Technology
[0002] As a key component of internal combustion engines, the piston pin's performance directly affects engine efficiency and lifespan. With advancements in materials science and manufacturing processes, piston pin performance has continuously improved, meeting the high-performance demands of modern engines. In the future, with increasing environmental and energy-saving requirements, piston pin design and manufacturing will move towards lightweighting, high strength, and long service life.
[0003] During the processing of piston pins, an oil injection device is required to inject oil into the piston pins. However, the oil injection device has reduced efficiency in injecting oil into the piston pins. Workers need to fix the piston pins on the fixing mechanism, and after the oil injection is completed, the piston pins are removed from the fixing mechanism. Only by reinstalling new piston pins on the fixing mechanism can a second oil injection be completed. This results in inconsistent oil injection of a batch of piston pins by the oil injection device, which greatly reduces the oil injection efficiency of the oil injection device for piston pins. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides a piston pin processing and oiling device, which has the advantages of efficient oiling of piston pins and solves the problem of low oiling efficiency of existing oiling devices.
[0005] This utility model discloses a piston pin machining oil injection device, comprising a worktable. A connecting plate is located on the left side of the top of the worktable, and a bearing plate is located on the top right side of the connecting plate. An oil injection assembly is located on the top of the bearing plate. A rotating assembly, including a turntable, is located on the right side of the top of the worktable. A motor is located below the turntable and on the right side of the bottom of the worktable. The output end of the motor passes through and extends to the top of the worktable, where it is fixedly connected to the turntable. Six limiting rings are equidistantly arranged on the top of the turntable. Clamping plates are provided on both sides of the inner cavity of each limiting ring. An inclined plate is provided on the top of each clamping plate. A spring is provided at the connection point between the outer side of the clamping plate and the limiting ring. Six ball bearings are movably embedded at equal intervals at the bottom of the turntable, with the surface of the ball bearings in close contact with the worktable. In this utility model, the bottom of the piston pin is first inserted into the clamping plate. The inclined plate on the clamping plate facilitates the insertion of the piston pin. After the piston pin is inserted into the clamping plate, the clamping plate moves outward, causing the spring to move outward. At this time, the spring... The inertia and clamping plate work together to fix the piston pins within the limiting rings. Six piston pins can be fixed within six limiting rings in sequence. Then, the oiling assembly injects oil into the piston pins directly below. After oiling is complete, the motor starts, driving a turntable to rotate. Ball bearings ensure stable rotation of the turntable, which in turn drives the limiting rings to rotate. When another limiting ring rotates to directly below the oiling assembly, the motor stops, and the oiling assembly injects oil into another piston pin. At this point, the previous limiting ring... Once the piston pin has been filled with oil in the retaining ring, the operator can remove it and replace it with an unfilled piston pin placed in the retaining ring. By repeating this process of removing and installing the piston pin in the retaining ring, oil filling can be performed continuously. This avoids the need for the operator to fix the piston pin to the fixing mechanism, remove it from the fixing mechanism after oil filling, and then install a new piston pin on the fixing mechanism to complete the second oil filling. This process would not have resulted in intermittent oil filling of a batch of piston pins by the oil filling device, and would have greatly reduced the oil filling efficiency of the oil filling device for piston pins.
[0006] This invention relates to a piston pin machining oil injection device, wherein the oil injection assembly includes an electric push rod. The output end of the electric push rod extends through and to the bottom of the support plate, where an oil injection head is provided. The surface of the oil injection head is provided with an oil guide pipe. When oil injection is required, the electric push rod first operates, driving the oil injection head downward. When the oil injection head moves into the piston pin, an external hydraulic pump delivers oil to the oil guide pipe, which then transfers the oil to the oil injection head. The oil injection head then injects oil into the piston pin.
[0007] The piston pin machining oil injection device of this utility model has a connecting block fixedly connected to the bottom of the electric push rod, and the bottom of the connecting block is fixedly connected to the bearing plate. The connecting block can fix the electric push rod, so that the electric push rod can perform better when used and avoid the electric push rod shaking during use, which would lead to the unstable operation of the electric push rod.
[0008] The piston pin machining oil injection device of this utility model has a support frame fixedly connected to both ends of the left side of the connecting plate, and one end of the support frame is fixedly connected to the worktable. The support frame can fix the connecting plate, so that the connecting plate is more effective in use and avoids the connecting plate from moving during use, which would lead to the instability of the components on the connecting plate.
[0009] The piston pin machining oil injection device of this utility model has a support column at each of the four corners of the bottom of the worktable, and the bottom of the support column is provided with an anti-slip pad.
[0010] The piston pin processing oil injection device of this utility model has a fixed plate fixedly connected to the top of the motor, and the inner cavity of the fixed plate is fixedly connected to the worktable by fixing bolts. The fixed plate and fixing bolts can fix the motor, so that the motor can perform better when used and avoid the motor shaking during use, which would lead to the unstable rotation of the electric drive turntable.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. In this utility model, the bottom of the piston pin is inserted into the clamping plate. The inclined plate on the clamping plate facilitates the insertion of the piston pin. After the piston pin is inserted, the clamping plate moves outward, causing the spring to move outward. The spring's inertia, combined with the clamping plate, secures the piston pin within the limiting ring. Six piston pins can be secured within six limiting rings in sequence. Then, the oil injection assembly injects oil into the piston pin directly below. After oil injection is complete, the motor runs, driving a turntable to rotate. Ball bearings ensure stable rotation of the turntable, which in turn rotates the limiting ring. The remaining limiting ring rotates to the oil injection point. When the piston pin is directly below the component, the motor stops running, and the oiling component injects oil into another piston pin. At this time, the piston pin that has been oiled in the previous limit ring can be removed by the operator, and a piston pin that has not been oiled can be placed in the limit ring. By repeating the above process of removing and installing piston pins in the limit ring, oiling can be carried out continuously. This avoids the need for the operator to fix the piston pin to the fixed mechanism, and then remove the piston pin from the fixed mechanism after oiling, and then install a new piston pin on the fixed mechanism to complete the second oiling. This would result in discontinuous oiling of a batch of piston pins by the oiling device, which greatly reduces the oiling efficiency of the oiling device for piston pins.
[0013] 2. When oil injection is required, the electric push rod first operates, which drives the oil injection head to move downward. When the oil injection head moves into the piston pin, the external hydraulic pump delivers oil to the oil guide pipe, and the oil guide pipe transmits the oil to the oil injection head. The oil injection head then injects oil into the piston pin.
[0014] The connecting block can fix the electric linear actuator, which makes the electric linear actuator work better and avoids shaking during use, thus preventing the electric linear actuator from running unstablely.
[0015] The support frame can fix the connecting plate, which makes the connecting plate more effective during use and prevents it from moving and causing instability of the components on the connecting plate.
[0016] The motor can be fixed in place by using a fixing plate and fixing bolts, which makes the motor perform better during use and avoids the motor shaking during use, which would lead to unstable rotation of the electric drive turntable. Attached Figure Description

[0024] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.
[0025] Please refer to Figures 1-5. The piston pin machining oil injection device of this utility model includes a worktable 1. A connecting plate 5 is provided on the left side of the top of the worktable 1, and a bearing plate 4 is provided on the top right side of the connecting plate 5. An oil injection assembly 3 is provided on the top of the bearing plate 4. A rotating assembly 2 is provided on the right side of the top of the worktable 1. The rotating assembly 2 includes a turntable 201, which is located on the right side of the top of the worktable 1. A motor 206 is provided below the turntable 201, and the motor 206 is located on the right side of the bottom of the worktable 1. The output end of the motor 206 passes through and extends to the top of the worktable 1 and is fixedly connected to the turntable 201. The top of the turntable 201 is provided with equidistant... Six limiting rings 202 are provided. Each limiting ring 202 has a clamping plate 207 on both sides of its inner cavity. The top of each clamping plate 207 has an inclined plate 209. A spring 208 is provided at the connection between the outer side of the clamping plate 207 and the limiting ring 202. Six balls 203 are equidistantly embedded in the bottom of the turntable 201, with the surface of the balls 203 in close contact with the worktable 1. In this invention, the bottom of the piston pin is inserted into the clamping plate 207. The inclined plate 209 on the clamping plate 207 facilitates the insertion of the piston pin. After the piston pin is inserted into the clamping plate 207, the clamping plate 207 moves outward, which in turn drives the spring 208. 08 moves outward. At this time, the piston pin is fixed in the limiting ring 202 by the inertia of the spring 208 and the cooperation of the clamping plate 207. Six piston pins can be fixed in the six limiting rings 202 in sequence. Then, the oil injection component 3 injects oil into the piston pin directly below. After the piston pin is oiled, the motor 206 runs, driving the turntable 201 to rotate. The ball bearings 203 cooperate with the turntable 201 to rotate stably. The turntable 201 drives the limiting ring 202 to rotate. When another limiting ring 202 rotates to be directly below the oil injection component 3, the motor 206 stops running. Component 3 then injects oil into another piston pin. At this point, the piston pin that has been oiled in the previous limiting ring 202 can be removed by the operator, and a piston pin that has not been oiled can be placed in the limiting ring 202. By repeating the above process of removing and installing piston pins in the limiting ring 202, oiling can be carried out continuously. This avoids the need for the operator to fix the piston pin to the fixing mechanism, and then remove the piston pin from the fixing mechanism after oiling is completed, and then install a new piston pin on the fixing mechanism to complete the second oiling. This would result in the oiling device injecting a batch of piston pins intermittently, which would greatly reduce the oiling efficiency of the oiling device for piston pins.
[0026] The oil injection assembly 3 includes an electric push rod 301. The output end of the electric push rod 301 extends through and to the bottom of the support plate 4 and is provided with an oil injection head 303. The surface of the oil injection head 303 is provided with an oil guide pipe 304. When oil injection is required, the electric push rod 301 is operated first, which drives the oil injection head 303 to move downward. When the oil injection head 303 moves into the piston pin, an external hydraulic pump delivers oil to the oil guide pipe 304. The oil is then transferred to the oil injection head 303 through the oil guide pipe 304, and oil is injected into the piston pin through the oil injection head 303.
[0027] The bottom of the electric push rod 301 is fixedly connected to a connecting block 302, and the bottom of the connecting block 302 is fixedly connected to the bearing plate 4. The connecting block 302 can fix the electric push rod 301, so that the electric push rod 301 performs better when in use and avoids the electric push rod 301 shaking during use, which would lead to the unstable operation of the electric push rod 301.
[0028] Both ends of the left side of the connecting plate 5 are fixedly connected to support frames 6, and one end of the support frame 6 is fixedly connected to the workbench 1. The support frame 6 can fix the connecting plate 5, so that the connecting plate 5 is more effective in use and avoids the connecting plate 5 from moving during use, which would lead to the instability of the components on the connecting plate 5.
[0029] The workbench 1 has four support columns 7 at the bottom corners, and the bottom of the support columns 7 is provided with anti-slip pads 8.
[0030] A fixing plate 205 is fixedly connected to the top of the motor 206, and the inner cavity of the fixing plate 205 is fixedly connected to the worktable 1 by fixing bolts 204. The fixing plate 205 and fixing bolts 204 can fix the motor 206, so that the motor 206 performs better when in use and avoids the motor 206 shaking during use, which would lead to the unstable rotation of the electric drive turntable 201.
[0031] When using this utility model: First, the bottom of the piston pin is inserted into the clamping plate 207. The inclined plate 209 on the clamping plate 207 facilitates the insertion of the piston pin into the clamping plate 207. After the piston pin is inserted into the clamping plate 207, the clamping plate 207 will move outward. The clamping plate 207 will drive the spring 208 to move outward. At this time, the inertia of the spring 208 and the clamping plate 207 will cooperate to fix the piston pin in the limiting ring 202. Six piston pins can be fixed in six limiting rings 202 in sequence. Then, the oil injection component 3 injects oil into the piston pin directly below. After the piston pin is oiled, the motor 206 runs, driving the turntable 201 to rotate. The ball bearings 203 cooperate with the turntable 201 to rotate stably. The turntable 201 drives... When the limiting ring 202 rotates, and another limiting ring 202 rotates to directly below the oiling component 3, the motor 206 stops running. The oiling component 3 then injects oil into another piston pin. At this time, the piston pin that has been oiled in the previous limiting ring 202 can be removed by the operator, and a piston pin that has not been oiled can be placed in the limiting ring 202. By repeating the above process of removing and installing piston pins in the limiting ring 202, oiling can be carried out continuously. This avoids the need for the operator to fix the piston pin to the fixing mechanism, and then remove the piston pin from the fixing mechanism after oiling is completed, and then install a new piston pin on the fixing mechanism to complete the second oiling. This would result in the oiling device injecting a batch of piston pins intermittently, which would greatly reduce the oiling efficiency of the oiling device for piston pins.
[0032] When oil injection is required, the electric push rod 301 is operated first, which drives the oil injection head 303 to move downward. When the oil injection head 303 moves into the piston pin, the external hydraulic pump delivers oil to the oil guide pipe 304, and the oil guide pipe 304 transmits the oil to the oil injection head 303. The oil injection head 303 is then used to inject oil into the piston pin.
[0033] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
