Description

Technical Field

[0001] The present invention relates to the technical field of camshaft production, and particularly to an automated physical detection and blanking system for a camshaft. Background Art

[0002] The camshaft is an important transmission component in a piston engine that controls the opening and closing of the valves. The machining accuracy requirements of the camshaft are high, and generally require multiple machining steps: rough turning of the journal, cam - rough grinding - finish grinding - polishing.

[0003] In the prior art, automatic production equipment is mostly used for the machining of camshafts. For example, in invention patents such as CN111958247B and CN112621118A, various technical solutions are provided to improve the machining accuracy and automation degree of the camshaft. In order to ensure the realization of precision machining of the camshaft, inspection is also required for the loading and unloading between each step or the initial incoming materials to ensure the effectiveness of subsequent machining. Summary of the Invention

[0004] The purpose of the present invention is to provide an automated physical detection and blanking system for a camshaft. The present invention effectively realizes automatic blanking and coordinates with the detection rhythm of the camshaft during the blanking process, which is beneficial to improving the machining accuracy of the camshaft.

[0005] To solve this technical problem, the technical solution of the present invention is: an automated physical detection and blanking system for a camshaft, including a bracket, a conveying device for moving the camshaft that has undergone physical detection, and a self - weight traction collection device for collecting the camshafts one by one;

[0006] The conveying device includes a horizontally arranged conveyor belt and a motor arranged on the side of the bracket to drive the conveyor belt;

[0007] The self - weight traction collection device successively includes a receiving component, a receiving member with receiving grooves arranged at equal intervals, and a positioning and supporting component from top to bottom;

[0008] The self - weight traction collection device further includes a traction component;

[0009] The receiving component is located at the blanking side below the conveyor belt; the receiving component is fixedly connected to the bracket to guide the camshaft from the conveyor belt to the receiving member;

[0010] The positioning and supporting component includes a support plate with a horizontal support surface. A mounting plate is vertically arranged on the support plate near the blanking side of the conveyor belt; the receiving member moves relative to the support plate under the action of the pulling component;

[0011] The traction assembly includes a fixed pulley mounted on the mounting plate and a pair of movable pulleys arranged relatively to the storage member, and also includes a pulling rope, one end of which is fixed to the mounting plate, and the middle part of the pulling rope is passed through the movable pulley, the fixed pulley and another movable pulley in sequence, and then is tensioned and connected to the guide rod in the receiving assembly through a baffle plate fixed relatively to the pulling rope and arranged at uniform intervals;

[0012] The guide rod includes an inclined portion for guiding the cam shaft toward the receiving member and a horizontal portion for storing the baffle plate, which are continuously arranged;

[0013] When the camshaft moves from the unloading position of the conveyor belt to the guide rod of the receiving assembly, a baffle contacts the falling camshaft, and the camshaft slides along the receiving assembly toward the receiving piece, pulling the pulling rope to pull the receiving piece toward the unloading direction of the receiving assembly.

[0014] As a further improvement, the storage member is provided with adjacent storage grooves for accommodating the camshaft at equal intervals, and the distance between two adjacent storage grooves is L1, and the distance between the two baffles when the pulling rope is tensioned is L2, wherein 4L1=L2.

[0015] Preferably, the length of the inclined portion is L3, wherein L3=L2.

[0016] Through the above arrangement, each camshaft unloading automatically pulls the storage part to move an equal distance. Therefore, the automatic collection of the camshafts after unloading is not limited by the production rhythm of the front-end automated physical inspection, and the unloading collection is flexibly and reliably realized.

[0017] The baffle plate and the guide rod are further improved to form a nested structure, and move along the guide rod under the action of the pulling rope. The present invention uses the guide rod to form contact between the baffle plate and the cam shaft, and further ensures that the next baffle plate moves from the horizontal part to the unloading position of the conveyor belt, waiting for the next unloading.

[0018] The baffle is further improved to have a rigid shielding plate and a connecting portion with a groove. The present invention uses a rigid baffle to ensure that the baffle and the guide rod have a space for relative sliding, and at the same time, the shielding portion of the baffle and the camshaft have stable contact, and the camshaft effectively pushes the baffle downward while sliding, thus achieving pulling.

[0019] Further improvement, the receiving assembly is fixedly connected to the bracket; the receiving assembly includes a horizontally arranged fixing plate, the guide rod is arranged in the middle of the fixing plate, and two auxiliary pieces are arranged on both sides of the guide rod parallel to the inclined portion of the guide rod. The present invention utilizes the auxiliary space and the guide rod to cooperate with the concave-convex structure of the camshaft to protect the camshaft from scratching the surface during the blanking process.

[0020] As a further improvement, a rounded structure for the baffle to flip and detach from the guide rod is provided at the end of the connection between the guide rod and the fixed plate in the material discharge direction.

[0021] As a further improvement, the baffles are pulled down one by one to a hollow position below the fixed plate, in the middle of the storage member.

[0022] The present invention uses the above arrangement to concentrate the baffle plate pushed down by the camshaft below the fixed plate and at a position that is also hollow in the storage member, thereby avoiding affecting the above material removal process.

[0023] As a further improvement, a plurality of rolling bearings in contact with the storage member are evenly distributed on one side of the support plate facing the storage member. In the present invention, the relative movement resistance between the storage member and the support plate is small, and equidistant pulling is stably achieved.

[0024] As a further improvement, the movable pulleys arranged in pairs are symmetrically arranged relative to the fixed pulleys. The self-weight pulling process is carried out stably.

[0025] By adopting the above technical solution, the beneficial effects of the present invention are:

[0026] The present invention utilizes the cooperation of the conveying device and the self-weight traction collection device. The conveying device moves the camshaft that has undergone the automated physical inspection along the receiving assembly after unloading from the conveyor belt. While moving along the receiving assembly, the baffle closest to the camshaft is pushed to pull the pulling rope to drive the storage component to move relative to the positioning support component toward the direction of the camshaft leaving the receiving assembly and enter the storage component.

[0027] Each camshaft pushes the baffle to pull the storage piece when it is unloaded, which facilitates the timely automatic collection and storage of the camshafts that have completed automated material inspection, avoids collisions of the camshafts, improves unloading efficiency, protects the camshafts, and facilitates subsequent production.

[0036] In this embodiment, the storage member 32 is provided with V-shaped grooves for accommodating the camshaft at equal intervals, the distance between two adjacent V-shaped grooves is L1, and the distance between the two baffles 344 when the pulling rope 343 is tensioned is L2, where 4L1=L2. In this embodiment, the length of the inclined portion 3111 is L3, where L3=L2.
