Description

Technical Field

[0001] The present invention belongs to the field of hardware tool processing, and particularly relates to an automatic device for processing the opening surface of a workpiece. Background Art

[0002] In the prior art, for the processing of the opening surface of a workpiece, a worker holds the workpiece, places it in a fixture for clamping and then processes it, and then takes out the workpiece after processing. This has low work efficiency, high labor intensity, high risk coefficient, and will affect the rhythm of automatic processing. Summary of the Invention

[0003] In view of the above problems, the present invention provides an automatic device for processing the opening surface of a workpiece, which realizes full-automatic feeding, automatic milling of the opening surface for processing, and discharging, significantly improving the processing efficiency and reducing the labor cost in production.

[0004] The solution provided by the present invention is as follows: An automatic device for processing the opening surface of a workpiece, comprising a feeding device and a processing device. The feeding device is matched with the processing device. The processing device includes a tooling mechanism and a processing mechanism. The basic principle of the present invention is that the feeding device automatically sends the workpiece to the processing mechanism. The tooling mechanism is responsible for loading the sent workpiece to the processing position and clamping it. The processing mechanism is responsible for processing the workpiece. When the processing mechanism finishes processing one workpiece, the tooling mechanism automatically unloads the processed workpiece, and then loads a new workpiece to the processing position for the next cycle of processing.

[0005] Specifically, the tooling mechanism includes a movable jaw and a loading mechanism. The loading mechanism is arranged above the movable jaw and is matched with the movable jaw. The loading mechanism includes a feeding port and a limiting pawl. The feeding port corresponds to the positions of the feeding device and the movable jaw respectively. The limiting pawl is arranged in the feeding port. The feeding port of the present invention is correspondingly matched with the feeding device, and the workpiece sent by the feeding device can accurately fall into the feeding port and be limited by the limiting pawl. The limiting pawl is used to control the switch between the feeding port and the movable jaw. When the limiting pawl is opened, the workpiece can fall into the movable jaw for clamping, processing and other operations.

[0006] Furthermore, the limit pusher includes an upper limit pusher and a lower limit pusher, and the upper limit pusher and the lower limit pusher cooperate with each other, and the upper limit pusher and the lower limit pusher do not cooperate with the feed port at the same time. The distance between the upper limit pusher and the lower limit pusher is equivalent to the height of the workpiece, so that the space between the upper limit pusher and the lower limit pusher serves as a "preparation position" for loading the workpiece. Specifically, when the upper limit pusher is in an open state, the lower limit pusher is closed, so that a workpiece falls into the above-mentioned "preparation position"; when the lower limit pusher rotates open, the workpiece in the "preparation position" falls into the processing position in the movable jaws, and at the same time, the upper limit pusher is closed to prevent excess workpieces from falling; when the lower limit pusher is reset to closed, the upper limit pusher is opened in a linked manner, and a new workpiece falls into the "preparation position" to wait for the next cycle operation.

[0007] The movable jaws of the present invention include jaws and an oil pump, and the jaws can be clamped and released by the action of the oil pump.

[0008] The processing mechanism includes a slide, a milling power head and a milling cutter. The slide can reciprocate between the farthest end and the nearest end along the processing direction. The milling cutter and the power head are fixed on a frame. The milling cutter and the power head cooperate with the movable jaws, and the slide cooperates with the limit claw. In the process of the slide moving from the nearest end to the farthest end, the power head and the milling cutter complete the processing of the workpiece surface.

[0009] The slide is also provided with a first sensor, which cooperates with the movable jaws. When the slide moves to the farthest end, the milling cutter completes processing the workpiece, and after the first sensor receives the position signal of the slide, the oil pump is started once to release the jaws and the workpiece falls.

[0010] The limit rod is provided with a second sensor, the limit plate is fixed on the machine body, and the second sensor cooperates with the oil pump. When the workpiece falls into the jaws from the feed port, the limit rod limits the workpiece at the processing position, and the contact (forging) between the workpiece and the limit rod generates a signal. After receiving the signal, the oil pump starts once, the jaws are clamped, and the workpiece is fixed at the processing position.

[0011] The above-mentioned processing position refers to the part of the workpiece to be processed that can extend out of the jaws and be processed with the milling cutter. The working position of the limit rod can accurately limit the fallen workpiece to the processing position and be clamped and fixed by the jaws.

[0012] The slide is provided with a lever, and when the slide reciprocates to the nearest end, the lever cooperates with the lower limit pusher claw. As mentioned above, in the normal state, the upper limit pusher claw is in the open state, and the lower limit pusher claw is in the closed state; when the slide moves from the farthest end to the nearest end, the lever pushes the lower limit pusher claw to move to the open state, and the upper limit pusher claw is linked, and when the slide moves to the nearest end, the lower limit pusher claw is in the open state, the upper limit pusher claw is in the closed state, and the workpiece in the "preparation position" falls into the caliper; when the slide moves to the farthest end, the elastic lever disengages from the lower limit pusher claw, and the limit pusher claw returns to its position.

[0013] The feeding device of the present invention comprises a vibrating plate and a workpiece channel, wherein the vibrating plate is connected with the workpiece channel, and the workpiece falls into the workpiece channel for transportation by the vibration of the vibrating plate. The workpiece channel cooperates with the feed port, and the workpiece channel is responsible for guiding the workpiece so that the workpiece can fall into the feed port.

[0014] The working principle of the present invention is: The feeding device delivers the workpiece to be processed to the feeding port. At this time, the upper limit pusher claw is in the open state, the lower limit pusher claw is in the closed state, and the workpiece to be processed falls into the "preparatory position".

[0015] The process of the slide moving from the farthest end to the nearest end is the loading process. During the movement, the elastic lever pushes the lower limit claw to rotate to the open state. When the slide moves to the nearest end, the lever pushes the lower limit claw to open, and the workpiece to be processed falls into the jaws and is limited in the processing position by the limit rod. The contact between the workpiece and the limit rod generates a signal, and the oil pump is controlled by the second sensor to start once, the jaws are clamped, and the workpiece is fixed in the processing position by the jaws.

[0016] The process of the slide moving from the nearest end to the farthest end is the processing and unloading process. During the movement, the power head and milling cutter fixed on the machine body complete the surface processing of the workpiece in the processing position. When the slide moves to the farthest end, the first sensor receives the position signal of the slide, controls the oil pump to start once, and the jaws are released, so that the workpiece can fall from the processing position to complete the unloading.

[0017] Compared with the prior art, the present invention has the following advantages: 1. The present invention realizes full-automatic loading, workpiece surface processing and unloading, which significantly improves the processing efficiency and reduces the labor cost in production.

Embodiment

[0020] The following is a further description of the present invention in conjunction with embodiments.

[0021] As shown in the figure, an automatic device for machining the orifice surface of a workpiece includes a feeding device and a machining device. The feeding device, the power head, and the limit plate are all installed on the overall installation base frame.

[0022] The feeding device includes a vibrating bowl 5 arranged above the device. The workpiece outlet of the vibrating bowl 5 is connected to an inclined workpiece channel, and the workpiece 4 slides down through the workpiece channel under the action of its own gravity. The workpiece guiding channel is provided with a lower limit pawl 7 at the lower part and an upper limit pawl 6 at the upper part. The upper limit pawl 6 and the lower limit pawl 7 are linked by the same rotating shaft 3. The rotating shaft 3 is fixedly connected to the outside of the feeding port, and a return spring is installed on the rotating shaft 3 or the limit pawl to achieve the return function. The upper limit pawl 6 and the lower limit pawl 7 have the same shape and can cooperate with the shape of the workpiece 4 to limit the workpiece and prevent the workpiece from falling in the feeding port. The distance between the two limit pawls is the same as the height of the workpiece 4, so that one workpiece can just be located between the two limit pawls. The space between the two limit pawls is defined as the "preparation position" to prevent unnecessary workpieces from falling at one time.

[0023] Through the action of the rotating shaft 3, the two limit pawls can rotate and switch between the open state and the closed state. In the default state, that is, the state where the above-mentioned return spring is not deformed, the lower limit pawl 7 is in the closed state, and at the same time, the upper limit pawl 6 is in the open state; when the lower limit pawl 7 is toggled, the two limit pawls rotate synchronously, that is, the lower limit pawl 7 rotates to the open state, and the upper limit pawl 6 rotates synchronously to the closed state; when the lower limit pawl 7 is no longer stressed, under the action of the return spring, the two limit pawls return to the default state.

[0024] The lower end of the feeding port is aligned with the middle seam position of the jaw, so that after the workpiece 4 falls from the feeding port, it can fall into the jaw 9 and then be clamped by the jaw 9. The jaw is powered by an oil pump (not shown in the figure). Each time the oil pump outputs, the jaw 9 can switch between the clamping / loosening state. The oil pump can be arranged on one side of the entire device by a bracket.

[0025] The position where the workpiece 4 falls into the jaws 9 for clamping is the "processing position" of the workpiece. Specifically, after being fixed in the "processing position", the surface to be processed of the workpiece can extend out of the jaws 9 and be processed by the milling cutter 10. The slide 8 is installed on the mounting base, and the slide 8 is reciprocated in a horizontal position by an oil pump or a plunger pump or a motor. The direction of movement is reciprocating along the vertical direction of the power head and the milling cutter. The position where the slide 8 is closest to the milling cutter 10 is the nearest end of the reciprocating motion, and the position where the slide is farthest from the milling cutter is the farthest end of the reciprocating motion. The horizontal position of the slide 8 is slightly lower than the power head and the milling cutter, and is parallel to the limit rod 2. The horizontal position of the power head 1 and the milling cutter 10 can be aligned with the "processing position" in the jaws 9, and can cooperate with the "processing position" workpiece to perform milling processing on the processing surface of the workpiece 4. When the slide 8 is at the nearest end, the milling cutter 10 is at the near end of the "processing position". When the slide 8 moves to the farthest end, the workpiece 4 moves from the near end to the far end of the milling cutter 10, and the workpiece is milled in the process. A position sensor is installed at the farthest end of the slide 8, and the signal of the position sensor is connected to the oil pump. A lever extending vertically upward is installed on the surface of the slide, and the bottom end of the lever can be directly welded to the surface of the slide and installed on the side close to the jaw 9. The specific position is: the position of the lever 11 corresponds to the lower limit finger 7, and the height is based on being able to contact the lower limit finger 7. In the process of the slide 8 moving from the farthest end to the nearest end, the lever 11 contacts the lower limit finger 7 and gradually moves. When the slide 8 moves to the nearest end, the lever 11 moves the lower limit finger 7 from the closed state to the open state, and the upper limit finger 6 is linked to the closed state; in the process of the slide 8 moving to the farthest end, the lever 11 is out of contact with the lower limit finger 7, and the lower limit finger 7 returns to the closed state under the action of the return spring.

[0026] The working logic of the present invention is: in the initial state, the slide 8 is located at the farthest end, the lower limit finger 7 is in the closed state, there is a workpiece in the "preparation position" between the upper and lower limit finger, and the jaws are in a loose state. When the equipment is working, the slide 8 moves from the farthest end to the nearest end. During the movement, the lever 11 contacts the lower limit finger 7 and moves the lower limit finger 7 to the open state. When the slide moves to the nearest end, the lever 11 rotates the lower limit finger 7 to the open state, and the workpiece 8 in the "preparation position" falls into the jaws 9 and is blocked by the limit rod of the "working position". The workpiece is limited in the "working position". When the workpiece 4 contacts the limit rod 2, the vibration sensor is triggered, and the signal is sent to the oil pump. The oil pump starts to work once, and the jaws are clamped to clamp the workpiece 4 in the "processing position" to complete the loading. During the loading process, the jaws 9 are unloaded and the milling cutter 10 does not work; the upper limit finger 6 rotates synchronously to the closed state to prevent the workpiece from falling into the "preparation position".

[0027] When the sliding table 8 moves from the nearest end to the farthest end, the milling cutter 10 contacts the machining surface of the workpiece 4 at the "machining position" and performs milling machining. At the same time, the dial rod 11 gradually disengages from the lower limit pawl 7, and the lower limit pawl 7 returns to the closed state under the action of the return spring, and the upper limit pawl 7 synchronously returns to the open state, and the workpiece 4 falls into the "preparation position". When the sliding table 8 moves to the farthest end, the position sensor is triggered, and the signal is transmitted to the oil pump, and the oil pump starts to work once, the caliper 9 is loosened, the workpiece is unloaded, and the next working cycle is entered.
