Description
Technical Field
[0001] The present invention relates to the field of connecting rod processing and manufacturing, and specifically to a connecting rod processing and manufacturing device. Background Art
[0002] Connecting rod processing and manufacturing is a machining process mainly used for producing connecting rod components that play a connecting and transmission role in various machinery. The process usually uses high-quality metal materials as blanks and applies various machining methods such as turning, milling, drilling, and grinding to precisely machine the blanks. Through these processes, the dimensional accuracy, shape accuracy, and surface roughness of the connecting rod are precisely controlled to ensure that the connecting rod can accurately achieve power transmission and motion conversion between components such as pistons and crankshafts in engines, compressors, etc., and meet the performance requirements of different machinery.
[0003] However, currently, when the connecting rod processing equipment grinds the billets after preliminary processing, it is usually inconvenient to simultaneously grind the outer walls on both sides of the billets, resulting in low grinding efficiency for the billets. In addition, currently, when the connecting rod processing equipment grinds the billets, it often cannot perform hole-opening operations simultaneously. Usually, hole-opening is carried out after grinding, resulting in a further reduction in processing efficiency. Summary of the Invention

[0006] Preferably, the grinding assembly includes a telescopic rod fixedly connected to the adjacent sides of the two sliders, one end of the telescopic rod is fixedly connected with a metal frame, a grinding wheel is rotatably connected to the middle end of the metal frame, and the outer wall of the grinding wheel abuts against the outer wall of the blank.
[0007] Preferably, a spring is sleeved on the outer wall of the telescopic rod, one end of the spring is connected to one side of the slider, the other end of the spring is connected to one side of the metal frame, and the slider and the metal frame are connected by two telescopic plates.
[0008] Preferably, the lifting assembly includes two rotating seats rotatably connected to the top side of the telescopic arm, a rotating ball is rotatably connected inside the rotating seat, a telescopic support rod is fixedly connected to the outer wall of the rotating ball, and a metal spherical shell is fixedly connected to the end of the telescopic support rod.
[0009] Preferably, a suspension rod is fixedly connected to the top side of the metal spherical shell, two limiting rails are opened at the middle end of the bottom side of the top plate, the top end of the suspension rod is slidably connected inside the limiting rails, and a joint ball is rotatably connected inside the metal spherical shell.
[0010] Preferably, a fixing rod is fixedly connected to the outer wall of the joint ball, a rotating seat is rotatably connected to the end of the fixing rod, and the rotating seat is rotatably connected to the top side of the drilling rig.
[0011] Preferably, the clamping assembly includes threaded rods fixedly connected to the left and right sides of the bottom side of the top plate, two clamping plates are arranged at the bottom sides of the threaded rods, and the end of the blank is located between the upper and lower clamping plates.

[0014] Preferably, a motor is installed on the left side of the fixing plate on the right side of the front side. The driving end of the motor is fixedly connected to the left end of the reciprocating lead screw. The outer wall of the motor is fixedly connected with a plurality of support rods. The top ends of the support rods are fixedly connected to the bottom side of the top plate. A control box for controlling the device is arranged on the left side of the top side of the top plate, and a toolbox for storing tools is arranged on the right side of the top side of the top plate.
[0015] Working principle: First, the staff places the pre-processed blank on the two supports, then grabs the clamping plate at the bottom side and rotates the turning handle to make the threaded rod rotate, thereby making the clamping plate at the top side move downward, so that the upper and lower clamping plates clamp the blank. Then, the motor and the drill are started through the control box. The motor drives the reciprocating lead screw to rotate, thereby making the slider at the front side move left and right. When the slider at the front side moves left and right, the telescopic arm will rotate, and when its two ends rotate to the middle position, it will contract due to its own telescopic characteristic, thereby driving the slider at the rear side to move left and right, and then driving the two grinding wheels to roll along the outer walls of the front and rear sides of the blank, so as to polish the outer wall of the blank through the grinding wheels. And due to the existence of the telescopic rod and the spring, the grinding wheels will be closely attached to the outer wall of the blank, so that the grinding wheels can better polish the blank. When the telescopic arm rotates, the swivel base on the top side of the telescopic arm will move and rotate following the rotation of the telescopic arm, thereby pushing the telescopic support rod to move, and making the telescopic support rod move more freely through the rotating ball, so that the telescopic support rod can move more conveniently. When the telescopic support rod moves, it will first contract, and when it contracts to the limit length and can no longer contract, it will move, thereby pushing the metal spherical shell to move, making the suspension rod slide in the limit rail, and making the metal spherical shell slide along the limit rail. When the metal spherical shell moves, it will move through the joint ball. When the joint ball moves, due to the guiding rod, the end of the fixed rod close to the drill will move downward, and the end connected to the joint ball will rotate following the movement of the joint ball, making the fixed rod push the drill downward, so that the drill performs hole-opening operations on both ends of the blank. Similarly, the rising of the drill will be completed when the telescopic arm rotates back to the initial position, so that the device can simultaneously perform double-sided polishing and end hole-opening operations on the blank.
[0016] The present invention provides a connecting rod processing and manufacturing device. It has the following beneficial effects: 1. By setting two sliders connected by a telescopic arm to drive the grinding wheels to move on the outer wall of the blank, and making the grinding wheels closely attached to the outer wall of the blank through the spring and the telescopic rod, the device can simultaneously polish the outer walls of both sides of the blank, improving the polishing efficiency of the device for the blank.
[0017] 2. In the present invention, the telescopic support rod can push one end of the fixed rod to move and rotate through the joint ball and the metal spherical shell, so that the other end of the fixed rod can push the drilling rig downward to move, enabling the drilling rig to perform hole-opening operations on the blank. As a result, while the equipment grinds the blank, it can also perform hole-opening operations on both ends of the blank simultaneously, further improving the processing efficiency of the equipment for the blank.
