Description

Technical Field

[0001] The utility model relates to the field of hardware processing, in particular to a device for removing burrs from the surface of hardware. Background Art

[0002] In various processing processes, there are discrepancies between the required shape and size, and the excess part derived from the processed parts is the burr. With the improvement of industrialization and automation, the harmfulness of burrs is particularly obvious, and has gradually attracted widespread attention. People have begun to study the generation mechanism and removal methods of burrs.

[0003] However, most of the deburring equipment on the market are handheld angle grinders or closed polishing machines, which have more or less defects in the working process. The angle grinder is prone to burrs sticking when working, which is not convenient for cleaning the stuck burrs, and the burrs are not removed evenly, which greatly affects the appearance of the hardware. The closed polishing machine is cumbersome to operate and requires frequent discharge and discharge of materials, resulting in low processing efficiency. Utility Model Content

[0004] In view of this, the utility model provides a hardware surface burr removal device, which can enable the hardware to continuously perform deburring work, improve the quality and efficiency of hardware deburring, and at the same time can clean the adhered burrs, so that the burrs are removed more evenly, making the hardware more beautiful.

[0005] The technical solution is: a hardware surface burr removal device, including a base frame, a movable frame, a contact wheel, a motor, a cam, a guide rod, a slide plate, a rocker arm, a push-pull rod and a grinding wheel cylinder. Grooves are opened on both sides of the base frame, the movable frame is rotatably connected to the base frame, the contact wheel is rotatably connected to the upper part of the base frame, a motor is provided on the movable frame, a cam is fixedly connected to the output shaft of the motor, the cam is composed of a large arc surface and a small arc surface, the cam is in contact with the contact wheel, a rocker arm is provided on the side of the cam away from the motor, and a push-pull rod is rotatably connected to the end of the rocker arm away from the cam, guide rods are provided on both sides of the movable frame, a slide plate is slidably connected between the two guide rods, a grinding wheel cylinder is rotatably connected to the slide plate, and the slide plate is rotatably connected to the push-pull rod.

[0006] Furthermore, a brush is also included, and the bottom of the skateboard is provided with a brush.

[0007] Furthermore, it also includes a magnetic push frame, a reset spring, a winding wheel and a traction rope. A magnetic push frame is slidably connected between the grooves on both sides of the base frame, and a reset spring is connected between the magnetic push frame and the two grooves of the base frame. Two winding wheels are rotatably connected to one end of the base frame close to the grinding wheel barrel, and two traction ropes are connected between the movable frame and the magnetic push frame. The two traction ropes are symmetrically arranged, and the traction ropes are wrapped around the winding wheels.

[0008] Furthermore, a plurality of protrusions are arranged on the grinding wheel cylinder.

[0009] The beneficial effects of the utility model are as follows: first, the hardware is placed on the top of the base frame manually and the motor is started. The output shaft of the motor drives the cam to rotate. When the cam rotates to the point where the contact wheel contacts the end point of the large arc surface of the cam, the cam drives the rocker arm to rotate, the rocker arm drives the push-pull rod to rotate, the push-pull rod drives the slide plate to move away from the motor, the slide plate drives the grinding wheel barrel to move away from the motor, the movable frame falls onto the base frame, the grinding wheel barrel contacts the hardware on the base frame, the grinding wheel barrel completes the deburring work of the hardware, and then the hardware that needs to be deburred is placed on the base frame again manually, and the process is repeated in sequence. The operation is simple and can improve the efficiency of deburring the hardware.

[0010] When the grinding wheel starts to rotate, the brush will brush off the burrs on the grinding wheel to prevent the burrs from sticking to the grinding wheel and causing poor deburring effect on the hardware, making the hardware more beautiful.

[0011] First, manually place the hardware on the side of the magnetic push rack away from the cam. When the cam rotates, the movable rack falls onto the base frame, the traction rope moves along the guide direction of the winding wheel, and the reset spring rebounds to its original position. The reset spring drives the magnetic push rack to move toward the cam, and the magnetic push rack drives the hardware to move onto the base frame. The cam continues to rotate, reciprocating in sequence, which can enable the hardware to be deburred continuously, reduce manual labor intensity, and further improve the efficiency of hardware deburring.

Grooves are provided on both sides of the base frame 1. The movable frame 2 is rotatably connected to the base frame 1. The contact wheel 3 is rotatably connected to the upper part of the base frame 1. The motor 4 is welded to the movable frame 2. The cam 5 is fixedly connected to the output shaft of the motor 4. The cam 5 consists of a large arc surface and a small arc surface. The cam 5 contacts the contact wheel 3, and the contact wheel 3 facilitates the rotation of the cam 5. A rocker arm 8 is welded to the side of the cam 5 away from the motor 4. The end of the rocker arm 8 away from the cam 5 is rotatably connected to the push-pull rod 9. Guide rods 6 are provided on both sides of the movable frame 2. A slide plate 7 is slidably connected between the two guide rods 6. The grinding wheel barrel 10 is rotatably connected to the slide plate 7. The grinding wheel barrel 10 is provided with a plurality of protrusions. The slide plate 7 is rotatably connected to the push-pull rod 9.

[0018] At first, the contact wheel 3 contacts the midpoint of the large arc surface of the cam 5, the grinding wheel barrel 10 is on the side close to the cam 5, and the movable frame 2 is raised to the highest point. First, the hardware is manually placed on the top of the base frame 1, and then the motor 4 is manually started. The output shaft of the motor 4 drives the cam 5 to rotate, and the cam 5 drives the rocker arm 8 to rotate, and the rocker arm 8 drives the push-pull rod 9 to rotate. When the cam 5 rotates to the end point of the contact wheel 3 and the large arc surface of the cam 5, the push-pull rod 9 drives the slide plate 7 to move slowly away from the motor 4, and the slide plate 7 drives the grinding wheel barrel 10 to move slowly away from the motor 4. The movable frame 2 naturally falls onto the base frame 1 under the action of gravity, and the grinding wheel barrel 10 contacts the hardware on the base frame 1. The cam 5 continues to rotate. When the cam 5 rotates to the end point of the contact wheel 3 and the When the midpoint of the small arc surface of the cam 5 contacts, the slide plate 7 drives the grinding wheel cylinder 10 to move quickly in the direction away from the motor 4, and the grinding wheel cylinder 10 initially completes the deburring work of the hardware, and the cam 5 continues to rotate. When the cam 5 rotates to the point where the contact wheel 3 contacts the end point of the small arc surface of the cam 5, the slide plate 7 drives the grinding wheel cylinder 10 to move quickly in the direction close to the motor 4, and the grinding wheel cylinder 10 completes the deburring work of the hardware, and the cam 5 continues to rotate. When the cam 5 rotates again to the point where the contact wheel 3 contacts the midpoint of the large arc surface of the cam 5, the grinding wheel cylinder 10 is on the side close to the cam 5, and the movable frame 2 is lifted to the highest point, and then the hardware that needs to be deburred is manually placed on the base frame 1 again, and it is reciprocated in sequence. The operation is simple and can improve the efficiency of hardware deburring.

[0019] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 2 As shown, a brush 11 is also included, and the bottom of the slide plate 7 is provided with a brush 11.

[0020] When the grinding wheel cylinder 10 starts to rotate, the brush 11 will brush off the burrs adhered to the grinding wheel cylinder 10 to prevent the burrs from adhering to the grinding wheel cylinder 10 and causing uneven deburring of the hardware, making the hardware more aesthetically pleasing.

[0021] Embodiment 3: Based on embodiment 2, Figure 1 , Figure 2 and Figure 3 As shown, it also includes a magnetic push frame 12, a reset spring 13, a winding wheel 14 and a traction rope 15. A magnetic push frame 12 is slidably connected between the grooves on both sides of the base frame 1, and a reset spring 13 is connected between the magnetic push frame 12 and the two grooves of the base frame 1. Two winding wheels 14 are rotatably connected to one end of the base frame 1 close to the grinding wheel barrel 10, and two traction ropes 15 are connected between the movable frame 2 and the magnetic push frame 12. The two traction ropes 15 are symmetrically arranged. The traction rope 15 passes around the winding wheel 14, and the winding wheel 14 facilitates the movement of the traction rope 15.

[0022] First, the contact wheel 3 contacts the midpoint of the large arc surface of the cam 5, the traction rope 15 is tightened, the reset spring 13 is stretched, the magnetic push frame 12 is pushed to the farthest point of the base frame 1, and the hardware is manually placed on the side of the magnetic push frame 12 away from the cam 5. The magnetic push frame 12 attracts the hardware. When the cam 5 rotates to the point where the contact wheel 3 contacts the end point of the large arc surface of the cam 5, the movable frame 2 naturally falls onto the base frame 1 under the action of gravity, so that the traction rope 15 is no longer tightened, and the traction rope 15 moves along the guide direction of the winding wheel 14, from The reset spring 13 rebounds to its original position, and the reset spring 13 drives the magnetic push frame 12 to move toward the direction close to the cam 5. The magnetic push frame 12 drives the hardware to move onto the base frame 1, and the cam 5 continues to rotate. When the contact wheel 3 contacts the midpoint of the large arc surface of the cam 5 again, the movable frame 2 is raised to the highest point again, and the magnetic push frame 12 drives the hardware to move in the opposite direction, thereby pushing out the hardware. This reciprocating process can enable the hardware to be deburred continuously, reduce the labor intensity, and further improve the efficiency of hardware deburring.
