Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing technology, and specifically relates to an automated punching equipment for the production and processing of automotive shock absorbers. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of springs after absorbing shock and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride comfort of the car. When driving over uneven roads, although the shock-absorbing springs can filter the vibrations from the road surface, the springs themselves will still have reciprocating motion. Shock absorbers are used to suppress this spring jumping. Automated punching equipment for the production and processing of automotive shock absorbers is equipment used to punch holes in automotive shock absorbers. However, traditional manual positioning is prone to deviations due to visual fatigue or operating habits. In addition, traditional punching equipment generates high-frequency vibration energy during operation, which may cause the workpiece to shift during vibration, resulting in workpiece breakage or deformation. In order to solve the problems mentioned above, we propose an automated punching equipment for the production and processing of automotive shock absorbers. Utility Model Content

[0003] The purpose of this utility model is to provide an automated punching equipment for the production and processing of automotive shock absorbers, which has the advantages of centering and fixing and punching protection.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automated punching equipment for the production and processing of automotive shock absorbers, comprising a left side plate, a support rod bolted to the top and bottom of the right side of the left side plate, a sliding rod fixedly sleeved inside the support rod, a connecting rod A bolted to the front and rear ends of the bottom of the sliding rod, a sliding sleeve slidably sleeved to the rear end of the surface of the sliding rod, a connecting rod B bolted to the opposite side of the two sliding sleeves, a limiting block bolted to the back of the connecting rod B, a limiting groove slidably connected to the back of the limiting block, a threaded sleeve bolted to the back of the limiting groove, a screw threadedly connected to the inside of the threaded sleeve, a clamping plate bolted to the back of the connecting rod A and the front of the connecting rod B, and a protective mechanism provided at the bottom of the left side plate.

[0005] The above technical solution involves the following steps: the screw rotation drives the screw sleeve to move; slider A and slide groove A limit the movement of the screw sleeve; the movement of the screw sleeve drives the limiting groove to move to the left; the limiting block is trapezoidal; when the limiting groove moves to the left, it presses against the limiting block, causing the limiting block to move forward; the limiting block drives the connecting rod B to move; the slide sleeve limits the movement of the connecting rod B; and the connecting rod B drives the clamping plate located at the rear to move forward, thus centering and clamping the workpiece. Centering can compensate for positional offsets caused by workpiece deformation or assembly errors, avoiding shock absorber installation failures caused by hole misalignment after punching. It can instantly and automatically complete workpiece positioning, and its features such as precise positioning, rapid response, and multi-specification adaptation significantly improve the quality, efficiency, and safety of automotive shock absorber punching processing, while reducing overall production costs.

[0006] The present invention is further configured such that the protective mechanism includes a base, the base being bolted to the bottom of the left side plate, a right side plate being bolted to the right side of the top of the base, a connecting plate A being bolted to the top left side of the right side plate, a connecting plate B being bolted to the middle left side of the right side plate, a cylinder being bolted to the bottom of the connecting plate A, a pressure plate being bolted to the bottom of the cylinder, springs A being bolted to the four corners of the bottom of the pressure plate, and the bottom of springs A being bolted to the four corners of the top of the connecting plate B, a damper being sleeved inside the springs A, and openings being provided at the center of the top and bottom of the connecting plate B.

[0007] The above technical solution employs a protective mechanism. The cylinder extends and retracts downwards, causing the pressure plate to move downwards. The pressure plate applies pressure to spring A, causing spring A to contract. The damper limits spring A, driving the main drive unit and drill bit downwards for punching. During punching, vibration occurs. Spring A contracts and rebounds to absorb the vibration force. The damper reduces the rebound of spring A, absorbing high-frequency vibration energy during equipment operation, reducing abnormal displacement between the drill bit and workpiece, ensuring continuous and stable punching, reducing downtime for adjustments, buffering instantaneous impacts, preventing metal parts from breaking or deforming due to stress concentration, dispersing the impact force of punching, reducing fatigue wear on key components such as drill bits, guide rails, and bearings, and extending the overall lifespan of the equipment.

[0008] The present invention is further configured such that a drive host is bolted to the center of the bottom of the pressure plate, and the surface of the drive host penetrates the interior of the opening; a drill bit is fixedly sleeved to the bottom of the drive host; and a sleeve is bolted to the bottom of the left side of the right side plate.

[0009] The above technical solution allows for punching of workpieces by setting up a drive host and a drill bit, and for fixing one end of the workpiece by setting up a sleeve.

[0010] The present invention is further configured such that a slider A is bolted to the back of the screw sleeve, and a groove A is provided on the front of the connecting rod A at the rear end, and the interior of the groove A is slidably connected to the surface of the slider A.

[0011] The above technical solution is adopted: by setting slider A and slider A, the movement of the screw sleeve can be limited.

[0012] The present invention is further configured such that sliders B are bolted to both sides of the inner wall of the opening, and grooves B are provided on both sides of the drive host, and the interior of the grooves B is slidably connected to the surface of the sliders B.

[0013] By adopting the above technical solution, the movement of the drive host can be limited by setting slider B and slider B.

[0014] The present invention is further configured such that a motor is fixedly sleeved on the left side of the screw, and the left side of the motor is bolted to the middle of the right side of the left side plate.

[0015] The above technical solution involves incorporating a motor to drive the screw to rotate.

[0016] The present invention is further configured such that a spring B is sleeved in the middle of the surface of the slide rod.

[0017] The above technical solution avoids excessive force when clamping the workpiece, thus preventing workpiece deformation.

[0018] The present invention is further provided that a protective pad is adhered to one side of each of the two clamping plates facing each other.

[0019] The above technical solution avoids excessive force when clamping the workpiece, thus preventing workpiece deformation, by setting up a protective pad.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1.
