Description

Technical Field

[0001] This utility model relates to an automatic turning rack for roller processing, belonging to the technical field of roller bearing production equipment. Background Technology

[0002] The spherical rollers of spherical roller bearings are machined from cylindrical steel billets using CNC machine tools. Currently, when mass-producing rollers on CNC machine tools, for medium to large-sized roller billets (weighing tens of kilograms), it is necessary to manually install each billet onto the CNC machine tool using a small lifting mechanism, which is time-consuming, labor-intensive, and inefficient. By setting up a robotic arm next to the CNC machine tool to automatically clamp and place the billets at the machining clamping position on the CNC machine tool, not only is the efficiency of billet clamping and loading improved, reducing the labor intensity of workers, but the clamping accuracy of the billets is also improved. However, with the improvement of the robotic arm's clamping efficiency, relying solely on manual preparation of billets to the designated picking position of the robotic arm can no longer meet actual production needs. Therefore, it is necessary to design a new rapid billet supply device for the robotic arm to realize automatic feeding during roller CNC machining, reduce the labor intensity of workers, and improve processing efficiency. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide an automatic rotating material rack for roller processing, which automatically places the cylindrical roller blanks one by one to the fixed picking position of the robot arm, thereby reducing the labor intensity of workers and improving processing efficiency.

[0004] The purpose of this utility model is achieved as follows:

[0005] An automatic tilting rack for roller processing includes a bracket, a support plate fixed on the bracket for batch placement of cylindrical blanks, a receiving seat rotatably mounted on the bracket, and an alignment cylinder fixed on the bracket for pushing the cylindrical blanks on the receiving seat.

[0006] The support plate is inclined on the left and high on the right, and the cylindrical blanks are arranged side by side on the support plate and roll from high to low according to their own weight.

[0007] The receiving seat is located at the lower left end of the support plate. It achieves two states by reciprocating back and forth: the first state is to receive the cylindrical blanks that roll out of the support plate one by one; the second state is to place the cylindrical blanks received in the first state to the gripping position of the robot arm, while preventing the cylindrical blanks on the support plate from continuing to roll down.

[0008] The alignment cylinder pushes the cylindrical blank received by the receiving seat to the limit position on the receiving seat for the robot to grasp.

[0009] Furthermore, the cross-section of the support plate is an inclined L-shaped groove, and the cylindrical blank is placed inclinedly in the L-shaped groove.

[0010] Furthermore, support ribs are provided on the support surface where the L-shaped groove contacts the outer circumferential surface of the cylindrical blank to reduce the friction force when the cylindrical blank rolls.

[0011] Furthermore, a movable limiting plate is provided on the receiving seat to adjust the position of the cylindrical blank on the receiving seat.

[0012] Furthermore, the movable limiting plate is provided with an elongated hole, through which a bolt passes to connect to the receiving seat.

[0013] Furthermore, the receiving seat is provided with a baffle plate perpendicular to the discharge direction of the support plate, which is used to prevent the cylindrical blank on the support plate from continuing to roll down in the second state of the receiving seat.

[0014] Furthermore, a deflection cylinder is hinged between the receiving seat and the bracket to control the deflection switching of the receiving seat between the two states.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses an inclined support plate to support cylindrical blanks. A receiving seat with two states—feeding to a robot and receiving material from the support plate—is set at the discharge end of the support plate. The blanks automatically enter the receiving seat using their own weight. A movable limiting plate is set on the receiving seat to accommodate cylindrical blanks of different specifications, and a baffle plate is set to allow cylindrical blanks on the support plate to enter the receiving seat as needed. This achieves automatic feeding for the robot, reduces the labor intensity of workers, and improves the efficiency of roller CNC machining. Attached Figure Description

[0023] See Figures 1-4 The present invention relates to an automatic turning rack for roller processing, comprising a bracket 1, a support plate 2 fixed on the bracket 1 for batch placement of cylindrical blanks 10, a receiving seat 3 rotatably disposed on the bracket 1, and an alignment cylinder 5 fixed on the bracket 1 for pushing the cylindrical blanks 10 on the receiving seat 3.

[0024] The support plate 2 is inclined from left to right, and the cylindrical blanks 10 are arranged side by side on the support plate 2 and roll from high to low according to their own weight. The cross-section of the support plate 2 is an inclined L-shaped groove. The cylindrical blanks 10 are placed inclined in the L-shaped groove. The support surface of the L-shaped groove in contact with the outer circumference of the cylindrical blank 10 is provided with support ribs 9, so that the line-plane contact between the outer circumference of the cylindrical blank 10 and the support surface of the support plate 2 is changed to point-line contact, reducing the contact area between the outer circumference of the blank and the support plate 2, reducing the friction when the cylindrical blank 10 rolls, and making the cylindrical blank 10 more stable and reliable when rolling automatically.

[0025] The receiving seat 3 is located at the lower left end of the support plate 2. A deflection cylinder 4 is also hinged between the receiving seat 3 and the bracket 1 to control the reciprocating deflection of the receiving seat 3. The receiving seat 3 achieves two states through reciprocating deflection: the first state is to receive the cylindrical blanks 10 rolling out of the support plate 2 one by one; the second state is to place the cylindrical blanks 10 received in the first state to the gripping position of the robot arm, while preventing the cylindrical blanks 10 on the support plate 2 from continuing to roll down; the deflection cylinder 4 controls the receiving seat 3 to deflect and switch between the two states.

[0026] The receiving seat 3 is provided with a movable limiting plate 6. The alignment cylinder 5 pushes the cylindrical blank 10 received by the receiving seat 3 to the limiting position set by the movable limiting plate 6, so that the robot can grasp it. The movable limiting plate 6 is provided with an elongated hole 7. The bolt passes through the elongated hole 7 and is connected to the receiving seat 3. The position of the movable limiting plate 6 on the receiving seat 3 is changed by using the elongated hole 7, thereby adjusting the position of the cylindrical blank 10 on the receiving seat 3. This can ensure that cylindrical blanks 10 of different specifications are always in the picking position of the robot.

[0027] In the first state of the receiving seat 3, the cylindrical blank 10 on the support plate 2 rolls down to the receiving seat 3 and stops rolling due to the obstruction of the movable limiting plate 6. The movable limiting plate 6 is adjusted so that only one cylindrical blank 10 rolls down to the receiving seat 3. Then, the deflection cylinder 4 pushes the receiving seat 3 to deflect to the second state. Since the receiving seat 3 is provided with a baffle plate 8 perpendicular to the discharge direction of the support plate 2, when the receiving seat 3 rotates to the second state, the baffle plate 8 will always prevent the cylindrical blank 10 on the support plate 2 from rolling down. When the rotation reaches the position where the robot arm is gripping the material, the rotation stops. At this time, the alignment cylinder 5 pushes the cylindrical blank 10 to the limiting angle formed by the movable limiting plate 6 and the receiving seat 3, fixing its position and ensuring that the blank can be accurately gripped by the robot arm. After the robot arm grabs the blank, the deflection cylinder 4 pushes the receiving seat 3 to deflect back to the first state, and the baffle plate 8 disengages from the discharge position of the support plate 2, releasing the obstruction of the cylindrical blank 10, so that the next cylindrical blank 10 rolls down to the receiving seat 3. Repeating the above two state switching can realize the continuous automatic feeding function.

[0028] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
