Description

Technical Field

[0001] This invention relates to the field of stepped shaft processing equipment, and in particular to an automatic feeding device for an automotive stepped shaft elastic transition clamp. Background Technology

[0002] Currently, the machining of automotive stepped shafts requires manual loading and processing. The specific operation is as follows: First, the operator holds the part in one hand and the elastic sleeve in the other; second, the elastic sleeve is placed onto the outer diameter of the part; third, the part and the elastic sleeve are simultaneously placed into the CNC machine tool's collet; fourth, after clamping the collet, the machine tool is started to begin the machining program; fifth, after machining is completed, the elastic sleeve and part are removed from the machine tool; sixth, the elastic sleeve and part are separated, the part is placed in a box, and the elastic sleeve operation is repeated in step one. Existing technology makes it easy to reverse the orientation during installation, and manual loading not only incurs high investment costs but also results in high labor intensity for the operators. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned shortcomings and defects of the prior art by providing an automatic feeding device for an elastic transition clamp for automotive stepped shafts, thereby solving the above-mentioned problems.

[0004] The technical problem solved by this invention can be achieved by the following technical solutions:

[0005] An automatic feeding device for a stepped axle of an automotive component with an elastic transition sleeve includes a feeding device, a tooling fixture, a feeding clamp, a transition sleeve clamp, a first position sensor, and a robotic gripper. The feeding device conveys the stepped axle workpiece to be processed, and its discharge end corresponds to the tooling fixture. The feeding clamp transfers the workpiece from the tooling fixture to the transition sleeve clamp. An elastic transition sleeve, cylindrical in shape, is provided within the transition sleeve clamp. A deformation slot is formed on the side of the elastic transition sleeve. The first position sensor is located on one side of the transition sleeve clamp to detect whether a stepped axle workpiece is present on the transition sleeve clamp. The robot gripper holds the stepped axle workpiece, along with the elastic transition sleeve, on the transition sleeve fixture and sends it to the processing area for processing and inspection. After the stepped axle workpiece is processed and inspected, the robot gripper then holds the processed stepped axle workpiece and sends it to the transition sleeve fixture. At this time, the bottom of the processed stepped axle workpiece is facing upwards, and the transition sleeve fixture clamps the elastic transition sleeve. When the next feeding fixture sends the stepped axle workpiece to the transition sleeve fixture, the stepped axle workpiece will drop the processed and inspected stepped axle workpiece down to the receiving point and insert itself into the elastic transition sleeve.

[0006] In a preferred embodiment of the present invention, a second position sensing sensor is further included, which is disposed at the discharge end of the feeding device to sense whether the material is in place.

[0007] In a preferred embodiment of the present invention, the feeding device includes a vibratory plate and a feeding track connected to the vibratory plate, wherein the discharge end of the feeding track corresponds to the tooling fixture.

[0008] In a preferred embodiment of the present invention, the tooling fixture includes a movable block and a linear motion drive device connected to the movable block, wherein the movable block is provided with a clamping groove corresponding to the discharge end of the feeding track.

[0009] In a preferred embodiment of the present invention, the feeding clamp includes a horizontal moving mechanism and a vertical moving mechanism disposed on the horizontal moving mechanism, and a first electric clamping arm is connected to the bottom end of the vertical moving mechanism.

[0010] In a preferred embodiment of the present invention, the transition sleeve clamp includes a fixing block with a U-shaped groove and a second electric clamping arm disposed above the U-shaped groove for clamping the elastic transition sleeve. The width of the U-shaped groove is smaller than the outer diameter of the elastic transition sleeve, the inner diameter of the elastic transition sleeve is smaller than the outer diameter of the upper outer frustum of the automotive stepped shaft workpiece, and the inner diameter of the elastic transition sleeve is larger than the outer diameter of all other parts of the automotive stepped shaft workpiece except for the upper outer frustum.

[0011] In a preferred embodiment of the present invention, the clamping surface of the second electric clamping arm is a cylindrical structure adapted to the outer cylindrical surface of the elastic transition sleeve.

[0012] Thanks to the above technical solution, this invention automates the detection and loading processes of automotive stepped shafts, greatly reducing the cost of equipment and labor investment. In addition, the loading and unloading processes after processing are both completed automatically by fixtures, avoiding heavy handling work for operators. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention is further described below.

[0021] See Figures 1 to 6 The automatic feeding device for the elastic transition sleeve clamp of the automotive stepped shaft shown includes a feeding device 100, a tooling fixture 200, a feeding fixture 300, a transition sleeve clamp 400, a first position sensing sensor 500, and a robot gripper 600.

[0022] The feeding device 100 is used to transport the workpiece 10 of the automotive stepped axle to be processed. The discharge end of the feeding device 100 corresponds to the tooling fixture 200. In this embodiment, the feeding device 100 includes a vibratory feeder 110 and a feeding track 120 connected to the vibratory feeder 110. The discharge end 121 of the feeding track 120 corresponds to the tooling fixture 200. The tooling fixture 200 includes a movable block 210 and a linear motion drive device 220 connected to the movable block 210. The movable block 210 is slidably mounted on the slide rail 211 of the frame, and the linear motion drive device 220 is a linear motor. The movable block 210 is provided with a clamping groove 212 corresponding to the discharge end 121 of the feeding track 120. Therefore, when the clamping groove 212 is aligned with the discharge end 121 of the feeding track 120, due to the preload of the feeding track 120, the frontmost automotive stepped shaft workpiece 10 at the discharge end 121 of the feeding track 120 will fall into the clamping groove 212 and then be moved by the movable block 210 to the bottom of the feeding fixture 300. The second position sensing sensor 700 is set at the discharge end of the feeding device 100 to sense whether the material is in place.

[0023] The feeding fixture 300 is used to feed the workpiece 10 of the automotive stepped shaft on the tooling fixture 200 into the transition sleeve fixture 400. In this embodiment, the feeding fixture 300 includes a horizontal moving mechanism 310 and a vertical moving mechanism 320 disposed on the horizontal moving mechanism 310. The bottom end of the vertical moving mechanism 320 is connected to a first electric clamping arm 330. The horizontal moving mechanism 310 includes a horizontal slide rail, and the vertical moving mechanism 320 includes a vertical motor. The vertical motor is horizontally slidably disposed on the horizontal slide rail, and the vertical motor is driven to move on the horizontal slide rail by a horizontal moving drive mechanism. The horizontal moving drive mechanism can be a horizontal motor.

[0024] The transition sleeve fixture 400 includes an elastic transition sleeve 410, which has a cylindrical structure and a deformation slot 411 on its side. The elastic transition sleeve 410 serves as a transition clamping element during machining, increasing the clamping area and stabilizing the machining of the part. The deformation slot 411 provides the clamping distance; without it, the fixture cannot clamp the part effectively, and it is necessary to transmit the clamping force of the fixture to the outer diameter of the part. In this embodiment, the transition sleeve clamp 400 includes a fixing block 420 with a U-shaped groove 421 and a second electric clamping arm 430 disposed above the U-shaped groove 421 for clamping the elastic transition sleeve 410. The groove width of the U-shaped groove 421 is smaller than the outer diameter of the elastic transition sleeve 410, the inner diameter of the elastic transition sleeve 410 is smaller than the outer diameter of the upper outer truncated cone 11 of the automotive stepped shaft workpiece 10, and the inner diameter of the elastic transition sleeve 410 is larger than the outer diameter of all other parts of the automotive stepped shaft workpiece 10 except for the upper outer truncated cone 11. Therefore, when the bottom of the automotive stepped shaft workpiece 10 passes through the elastic transition sleeve 410 from top to bottom, the automotive stepped shaft workpiece 10 will not fall out of the elastic transition sleeve 410 even if the second electric clamping arm 430 is not clamped. When the bottom of the automotive stepped shaft workpiece 10 passes through the elastic transition sleeve 410 from bottom to top, the automotive stepped shaft workpiece 10 will fall out of the elastic transition sleeve 410 if the second electric clamping arm 430 is not clamped. The clamping surface of the second electric clamping arm 430 is a cylindrical structure 431 adapted to the outer cylindrical surface of the elastic transition sleeve 410.

[0025] The first position sensing sensor 500 is set on one side of the transition sleeve fixture 400 to sense whether there is a vehicle step shaft workpiece 10 to be processed on the transition sleeve fixture 410.

[0026] The working principle of this invention is as follows:

[0027] The first piece 10 of the automotive stepped shaft to be processed at the discharge end 121 of the feeding track 120 falls into the clamping groove 212, and is then moved by the movable block 210 to the bottom of the feeding fixture 300. Next, the feeding fixture 300 sends the automotive stepped shaft to be processed from the tooling fixture 200 to the transition sleeve fixture 400, with the bottom of the automotive stepped shaft to be processed passing through the elastic transition sleeve 410 from top to bottom. The robot gripper 600 clamps the automotive stepped shaft to be processed along with the elastic transition sleeve 410 on the transition sleeve fixture 400 and sends it to the processing area for processing and inspection (the processing and inspection of the automotive stepped shaft to be processed 10 is existing technology and will not be described in detail here). Specifically, the robot gripper 600 can clamp the lower part of the automotive stepped shaft to be processed 10, and then rotate it 180° so that the bottom of the automotive stepped shaft to be processed 10 faces upwards, preventing the elastic transition sleeve 410 from falling off. After the automotive stepped axle workpiece 10 is processed and inspected, the robot gripper 600 clamps the processed automotive stepped axle onto the transition sleeve fixture 400. At this time, the bottom of the processed automotive stepped axle is facing upwards, and the transition sleeve fixture 400 clamps the elastic transition sleeve 410. When the next feeding fixture 300 feeds the automotive stepped axle workpiece 10 into the transition sleeve fixture 400, the automotive stepped axle workpiece 10 will drop the processed and inspected automotive stepped axle onto the receiving area and insert itself into the elastic transition sleeve 410. The robot gripper 600 then clamps the automotive stepped axle workpiece 10 on the transition sleeve fixture 400 together with the elastic transition sleeve 410 and sends it to the processing area for processing and inspection. This process is repeated. To improve processing efficiency, the robot gripper 600 can be set to two or more, with at least one for feeding and at least one for unloading, eliminating the need to wait for one robot gripper to complete its work before proceeding to the next step.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
