Description

Technical Field

[0001] This utility model relates to the field of connecting rod processing technology, specifically a connecting rod rough milling device. Background Technology

[0002] The core function of the connecting rod rough milling device is to lay a stable dimensional and shape foundation for subsequent finish machining. It requires rapid, precise, and secure clamping of the connecting rod blank to ensure that the workpiece does not shift or vibrate during machining. This is a prerequisite for guaranteeing key rough machining qualities such as the flatness and parallelism of the milled surface. An efficient clamping method is also crucial for improving the overall production efficiency of the rough milling process.

[0003] Existing devices for fixing connecting rods during rough milling mostly use a single clamping structure with limited adjustment range. When fixing and limiting connecting rods of different thicknesses, it is necessary to disassemble and reinstall the corresponding clamping structure, which is quite troublesome and results in low rough milling efficiency. To address these issues, a connecting rod rough milling device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a connecting rod rough milling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A sliding rod is fixedly connected to the bottom of the lower pressure plate, and a sliding hole is provided on the top of the rotating rod for sliding with the sliding rod. An adjustment component is provided at the bottom of the positioning plate for adjusting the sliding of the sliding rod.

[0007] The adjustment assembly includes a connecting rod and an adjusting block. The connecting rod is rotatably connected to the bottom of the slide rod, and the adjusting block is fixedly connected to the end of the connecting rod away from the slide rod. The top of the positioning plate has a through hole for inserting the adjusting block. A spring is sleeved on the connecting rod. One end of the spring is connected to the bottom of the slide rod, and the end of the spring away from the slide rod is connected to the bottom of the inner wall of the sliding hole. The adjusting block has through holes, and a set of through rods is inserted into the two sets of through holes. The bottom of the positioning plate is provided with an operating component for adjusting the movement of the through rods.

[0008] The sliding hole is connected to the through hole, and a limit block is slidably connected to the positioning plate. The positioning plate is provided with a fixing component for limiting the limit block.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1-4 In this embodiment, a connecting rod rough milling device includes a positioning plate 11, at least two sets of lower pressure plates 18, and a rotating rod 12 disposed on the top of the positioning plate 11. The bottom of the lower pressure plate 18 is fixedly connected to a sliding rod 17. The top of the rotating rod 12 is provided with a sliding hole 20 for sliding with the sliding rod 17. The bottom of the positioning plate 11 is provided with an adjustment component for adjusting the sliding of the sliding rod 17.

[0026] The adjusting assembly includes a connecting rod 15 and an adjusting block 14. The connecting rod 15 is rotatably connected to the bottom of the slide rod 17, and the adjusting block 14 is fixedly connected to the end of the connecting rod 15 away from the slide rod 17. The top of the positioning plate 11 has a through hole 13 for inserting the adjusting block 14. A spring 16 is sleeved on the connecting rod 15. One end of the spring 16 is connected to the bottom of the slide rod 17, and the end of the spring 16 away from the slide rod 17 is connected to the bottom of the inner wall of the sliding hole 20. The adjusting block 14 has two sets of through holes 22. A set of insert rods 23 are inserted into the positioning plate 11. The bottom of the positioning plate 11 is provided with an operating component for adjusting the movement of the insert rods 23. The operating component presses down on the insert rods 23, causing the insert rods 23 to drive the two sets of adjusting blocks 14 to move downward. This causes the sliding rod 17 to slide downward in the sliding hole 20 through the connecting rod 15. The sliding rod 17 moves downward and squeezes the spring 16, causing the lower pressure plate 18 to move downward and fix the top of the connecting rod. This makes it easier to fix connecting rods of different thicknesses, reduces the time of repeatedly changing the clamping structure, improves processing efficiency, and facilitates rough milling.

[0027] The sliding hole 20 is connected to the through hole 13, and the positioning plate 11 is slidably connected to the limiting block 28. The positioning plate 11 is provided with a fixing component for limiting the limiting block 28.

[0028] The operating components include an adjusting plate 24 and a screw 25. The adjusting plate 24 overlaps the top of the insert rod 23, and the screw 25 is rotatably connected to the bottom of the positioning plate 11. The adjusting plate 24 has a threaded hole for threaded connection with the screw 25. The bottom of the positioning plate 11 is fixedly connected to a guide rod 26. The adjusting plate 24 has a sliding hole for sliding with the guide rod 26. Rotating the screw 25 moves the adjusting plate 24 downward, and the adjusting plate 24 slides downward on the guide rod 26, pressing down on the insert rod 23. This causes the insert rod 23 to drive the two sets of adjusting blocks 14 to move downward.

[0029] Guide blocks 19 are fixedly connected to both sides of the slide rod 17, and guide grooves 21 are provided on both sides of the inner wall of the slide hole 20 for sliding in conjunction with the guide blocks 19. By setting the guide blocks 19 and the guide grooves 21, the sliding of the slide rod 17 can be limited and guided.

[0030] The bottom of the rotating rod 12 is rotatably connected to a base plate, which is connected to the positioning plate 11 by bolts. By setting the rotatable rotating rod 12, the lower pressure plate 18 can be easily adjusted and rotated.

[0031] The fixing assembly includes a positioning block 29 and a support frame 30. The positioning block 29 is fixedly connected to one side of the limiting block 28, and the support frame 30 is fixedly connected to the top of the positioning plate 11. The positioning block 29 is slidably connected inside the support frame 30. A set of fixing bolts 31 are threadedly connected to the support frame 30. The positioning block 29 has a fixing hole 32 for threaded connection with the fixing bolts 31. Pushing the positioning block 29 drives the limiting block 28 to fix one side of the connecting rod. Then, using an external tool to rotate the fixing bolts 31, they are screwed into the fixing hole 32 to fix the limiting block 28, thus fixing the connecting rod laterally.

[0032] Two sets of limiting rings 27 are threaded onto the insertion rod 23. One side of the limiting ring 27 overlaps with one side of the adjusting block 14. By setting the limiting ring 27, the adjusting block 14 can be limited, and the insertion rod 23 can be prevented from detaching from the insertion hole 22.

[0033] The top of the positioning plate 11 is fixedly connected with two sets of limiting posts for engaging the connecting rod. The surface of the limiting posts is provided with rubber pads to facilitate the engagement of the connecting rod. The rubber pads also serve to cushion and prevent slippage.

[0034] The working principle of this utility model is as follows: First, the connecting rod is secured to the two sets of limiting posts. The positioning block 29 is pushed to drive the limiting block 28 to fix one side of the connecting rod. Then, an external tool is used to rotate the fixing bolt 31, thereby screwing it into the fixing hole 32 to fix the limiting block 28. Next, the base plate is fixed to the positioning plate 11 with bolts. The lower pressure plate 18 is rotated, causing the rotating rod 12 to rotate. The two sets of lower pressure plates 18 rotate to above the connecting rod, allowing the insertion rod 23 to pass through the two sets of insertion holes 22. The limiting ring 27 is then screwed onto the insertion rod 23. The adjusting block 14 is limited, and the screw 25 is rotated to move the adjusting plate 24 downward. The adjusting plate 24 slides downward on the guide rod 26 and presses down on the insert rod 23, causing the insert rod 23 to drive the two sets of adjusting blocks 14 to move downward. This causes the sliding rod 17 to slide downward in the sliding hole 20 through the connecting rod 15. The sliding rod 17 moves downward and squeezes the spring 16, causing the lower pressure plate 18 to move downward and fix the top of the connecting rod. This makes it easier to fix connecting rods of different thicknesses, reduces the time of repeatedly changing the clamping structure, improves processing efficiency, and facilitates rough milling.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
