Description

Technical Field

[0001] This utility model relates to the field of oil pump technology, and in particular to a synchronous clamping device for oil pump processing. Background Technology

[0002] The oil pump is a crucial component of the engine. It is responsible for drawing oil from the oil pan and pressurizing it to deliver it to various friction parts of the engine to ensure proper lubrication and heat dissipation, thereby extending the engine's service life. The oil pump has high requirements for manufacturing processes because it requires precision machining to ensure the pump body's sealing, strength, and durability.

[0003] In traditional oil pump machining, clamping and limiting devices are used to ensure precision and accuracy. For machining the pump cover and body, traditional clamping methods require multiple manual clamping actions to meet workpiece positioning requirements, resulting in complex and inefficient operations. While improved pneumatic clamping allows clamping via air source switches, these actions are typically controlled by multiple cylinders. The order in which the air source switches are activated plays a crucial role in the workpiece clamping state and stress. Incorrect switch sequence can lead to insufficient workpiece machining accuracy. The aluminum alloy pump cover needs to be fitted to the pump body, with machining concentrated on the inner surface, requiring high precision and flatness of the mounting surface. Uneven workpiece clamping force can easily result in insufficient flatness accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the traditional clamping method is complicated and inefficient in the oil pump processing process. It is also complicated to operate, requiring accurate control of the switch operation sequence. At the same time, the processing part is concentrated on the inner side, with high precision requirements and high flatness requirements for the mounting surface. Uneven force on the workpiece clamping can easily lead to the workpiece flatness accuracy not meeting the requirements.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Figure 1 and Figure 2 The illustrated synchronous clamping device for oil pump processing includes a base 1. Two support plates 2 are mounted on the base 1 using third hexagon socket screws 14. A positioning plate 3 is fixedly mounted on the surface of the two support plates 2 using first hexagon socket screws 4. A support seat 10 is fixedly connected to the surface of the base 1 using second hexagon socket screws 11. A spring 12 is provided on the inner wall of the support seat 10. A floating support column 13 is installed on the other end of the spring 12. A set screw handle 15 is threaded through the surface of the support seat 10. A cylinder assembly 7 and a cylindrical sleeve 5 are provided on the surface of the positioning plate 3. A pressure plate 6 is slidably connected to the inner wall of the cylindrical sleeve 5. A pull plate 8 is fixedly mounted on the output end extension rod of the cylinder assembly 7 using bolts 16. The surface of the pull plate 8 is connected and fixed to one end of the pressure plate 6 using a flat nut 9.

[0024] Figure 1 - Figure 3 When using a clamping device to limit and fix a machined oil pump workpiece, the components of the device are first connected and assembled. Before machining, the extension height of the pressure plate 6 in its natural state is adjusted using the flat nut 9 to match the height difference of the three clamping points on the workpiece. Then, the workpiece is placed on the tooling positioning plate 3. At this time, the workpiece is restricted in three degrees of freedom by the fixed support column on the positioning plate 3 and in two degrees of freedom by the two positioning pins on the positioning plate 3. Then, the machine tool pneumatic system valve is activated to run the cylinder group 7, causing its output end to extend, thereby driving the pull plate 8 to move downward. At this time, the three pressure plates 6 engaged on the pull plate 8 by the thread will move downward synchronously along the cylindrical sleeve 5, clamping the workpiece. Then, the floating support column 13 will slide and rise on the inner wall of the support seat 10 under the reaction force of the spring 12 until it precisely fits the workpiece. Then, rotate the set screw handle 15 on the support seat 10 so that the set screw handle 15 contacts and presses against the arc surface of the floating support column 13 to fix its position. After the processing is completed, close the rotary valve, the extension rod at the output end of the cylinder group 7 retracts, the pressure plate 6 connecting rod moves upward, releases the workpiece, and removes the workpiece. At this time, when the workpiece of the oil pump is being processed, the clamping action can be kept consistent under the action of the clamping device to ensure that the workpiece is subjected to uniform force and is not easily deformed. Moreover, the automatic adjustment of the floating support point improves the versatility and flexibility of the tooling, thereby improving the processing accuracy.

[0025] Figure 1 and Figure 3The pull plate 8 shown is fitted with conical washers 17 and spherical washers 18 on both sides of the position where it passes through the pressure plate 6. This enhances the installation effect of the flat nut 9. The conical washers 17 and spherical washers 18 ensure that when the flat nut 9 is threaded onto both sides of the pressure plate 6, it will stably fit and press against the surface of the pull plate 8, making it less likely to have gaps. This would prevent the flat nut 9 from loosening during long-term use and causing abnormal operation of the equipment. One end of the floating support column 13 is fixedly connected to a reinforcing pad 19. The reinforcing pad 19 improves the limiting effect of the floating support column 13. The rubber reinforcing pad 19 allows the end face of the floating support column 13 to fit more closely to the workpiece surface when in contact, making it less likely to have gaps, thus providing better support and limiting.

[0026] Figure 1 and Figure 2 A protective plate 20 is installed on the side of the pressure plate 6 near the positioning plate 3. The protective plate 20 improves the performance of the pressure plate 6. The protective plate 20, made of sponge material, allows the pressure plate 6 to better squeeze each other when pressing and limiting the workpiece, and is less likely to cause damage to the workpiece surface due to excessive squeezing force.

[0027] Figure 1 and Figure 5 A stabilizing rod 21 is installed on one side surface of the pressure plate 6 shown. The stabilizing rod 21 has threads on its arc surface. The stabilizing rod 21 is threaded through the inner wall of the set screw handle 15. A positioning knob 22 is threaded on the arc surface of the stabilizing rod 21. When the floating support column 13 is pressed against the workpiece by the reaction force of the spring 12, the set screw handle 15 on the stabilizing rod 21 can be rotated until the set screw handle 15 contacts and presses against the surface of the floating support column 13. Then, the positioning knob 22 threaded on the stabilizing rod 21 can be rotated until the positioning knob 22 contacts and presses against the surface of the set screw handle 15. At this time, the set screw handle 15 is not easy to rotate and loosen, thus better ensuring the stability of the workpiece position and facilitating processing operations.

[0028] Figure 4 and Figure 5 A reinforcing rod 23 is fixedly connected to the inner wall of the support base 10 shown. The reinforcing rod 23 is slidably connected to the inner wall of the floating support column 13. The reinforcing rod 23 makes the floating support column 13 more stable when it rises and slides under the elastic force of the spring 12 on the inner wall of the support base 10, and it is not easy to cause abnormal shaking, thereby improving the stability of use. A reinforcing sleeve 24 is fixedly connected to the arc surface of the floating support column 13. The reinforcing sleeve 24 improves the connection strength between the set screw handle 15 and the floating support column 13. The silicone reinforcing sleeve 24 further increases the friction when the set screw handle 15 and the floating support column 13 are in contact and squeezed, thereby making the floating support column 13 more stable when in contact with the workpiece.

[0029] Working principle: When using the clamping device to limit and fix the oil pump workpiece, first connect and assemble the various components of the device. Then, before processing, adjust the extension height of the pressure plate 6 in its natural state using the flat nut 9 to match the height difference of the three clamping points of the workpiece. Then, place the workpiece on the tooling positioning plate 3. At this time, the workpiece will be restricted in three degrees of freedom by the fixed support column on the positioning plate 3, and in two degrees of freedom by the two positioning pins on the positioning plate 3. Then, start the machine tool pneumatic system valve to run the cylinder group 7, causing its output end to extend, thereby driving the pull plate 8 to move downward. At this time, the three pressure plates 6 engaged on the pull plate 8 will move downward synchronously along the cylindrical sleeve 5 through the thread, clamping the workpiece. The workpiece is then lifted by the reaction force of the spring 12, and the floating support column 13 slides and rises on the inner wall of the support seat 10 until it precisely fits the workpiece. Then, the set screw handle 15 on the support seat 10 is rotated so that the set screw handle 15 contacts and presses against the arc surface of the floating support column 13 to fix its position. After the processing is completed, the rotary valve is closed, the extension rod at the output end of the cylinder group 7 retracts, the pressure plate 6 connecting rod moves upward, the workpiece is released, and the workpiece is taken out. At this time, when the workpiece of the oil pump is being processed, the clamping action can be kept consistent under the action of the clamping device, ensuring that the workpiece is subjected to uniform force and is not easily deformed. Moreover, the automatic adjustment of the floating support point improves the versatility and flexibility of the tooling, thereby improving the processing accuracy.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
