Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a deburring device for fastener production. Background Art

[0002] Burrs are thorns or flash formed at the intersection of the surfaces of parts. Although burrs are small, they directly affect the quality of products. In recent years, with the attention paid to burr removal in various industries, deburring methods have emerged in an endless stream. However, the existing deburring devices have the disadvantages of low deburring efficiency, poor deburring effect, and inability to deburr the inside and outside of the pipe mouth at the same time. Therefore, it is urgent to develop a forging deburring device with high deburring efficiency, good deburring effect, and the ability to deburr the inside and outside of the pipe mouth at the same time.

[0003] For example, a deburring device with publication number CN208019918U solves the problem that the existing deburring device has a relatively complex structure and low working efficiency. A deburring device comprises a base fixedly connected to the slide of a machine tool, a rotating shaft and a driving mechanism for driving the rotating shaft to rotate are axially fixedly connected to the base, a rotating member is fixedly connected to the outer end of the rotating shaft, and steel wires are evenly arranged on the outer side wall of the rotating member. A deburring device has the advantages of simple structure and high deburring efficiency.

[0004] However, for tubular fasteners, this technical solution cannot grind fasteners with different inner diameters and outer diameters, and can only grind fasteners of the same specification, so its applicability is relatively low. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a deburring device for fastener production.

[0006] The utility model is achieved in this way:

[0007] A deburring device for fastener production comprises a fixing mechanism body and a deburring mechanism body, the fixing mechanism body comprises a base, a first motor is installed on the top of the base, the deburring mechanism body comprises a driving sleeve, the driving sleeve is transmission-connected to the output end of the first motor, four groups of slots are provided on one side of the driving sleeve, and connecting plates are slid inside the slots, sandpaper is adhered to both sides of one end of the connecting plate, a pair of springs are connected between the connecting plate and the inner wall of the driving sleeve, a second motor is installed inside the driving sleeve, and the output end of the second motor is transmission-connected to an adjusting block, four groups of protrusions are equidistantly installed on the outside of the adjusting block, and the protrusions and the connecting plate are pressed against each other.

[0008] The beneficial effect of adopting the above-mentioned further scheme is that, firstly, the drive of the second motor can drive the adjustment block to rotate, thereby determining whether the protrusion is squeezed with the connecting plate, and the squeezing position of the protrusion and the connecting plate, so that the connecting plate moves in the slot, and then changes the size of the inner diameter and outer diameter surrounded by the four groups of connecting plates, so that fasteners of different sizes can be covered on the periphery of the connecting plate or inserted into the inner periphery of the connecting plate. Therefore, the device can adapt to fasteners with different outer diameters or inner diameters to improve the applicability of the device. Secondly, the first motor drives the driving sleeve to rotate, thereby causing friction between the four groups of connecting plates and the fasteners to achieve the purpose of deburring the fasteners.

[0009] Furthermore, the protrusion is arc-shaped, and the extrusion point between the connecting plate and the protrusion is a curved surface.

[0010] The beneficial effect of adopting the above further solution is that, due to the arrangement of the arc and the curved surface, the protrusion can be more easily squeezed with the connecting plate.

[0011] Furthermore, one side of one end of the connecting plate is set as a concave surface, and the other side of one end of the connecting plate is set as a convex surface.

[0012] The beneficial effect of adopting the above further solution is that when deburring a cylindrical fastener, the contact area of ​​the connecting plate to the fastener can be increased by using the concave surface and the convex surface.

[0013] Furthermore, a limit plate is installed inside the driving sleeve, and grooves are formed on four sides of the limit plate, and the connecting plate slides in the grooves.

[0014] Furthermore, the width of the groove and the slot is consistent with the width of the connecting plate.

[0015] The beneficial effect of adopting the above further solution is that by utilizing the limiting plate and limiting the size of the groove and the slot, the connecting plate can maintain stable linear motion.

[0016] Furthermore, a protective cover is installed on the top of the base, and the first motor is located inside the protective cover. A through hole is opened on one side of the protective cover, and the output end of the first motor is located in the through hole.

[0017] Furthermore, a heat dissipation groove is provided on the back of the protective cover, and a filter is installed in the heat dissipation groove.

[0018] The beneficial effect of adopting the above further solution is that the protective cover is used to provide protection for the first motor, and the heat dissipation groove is used to dissipate heat from the first motor.

[0019] Furthermore, a control panel is installed on the outer side of the protective cover, and the control panel is electrically connected to the first motor and the second motor.

[0020] The beneficial effects of the utility model are as follows: the utility model is a deburring device for fastener production obtained through the above design, firstly, using the drive of the second motor to drive the adjustment block to rotate, thereby determining whether the protrusion is squeezed with the connecting plate, and the squeezing position of the protrusion and the connecting plate, so that the connecting plate moves in the slot, and then changes the size of the inner diameter and outer diameter surrounded by the four groups of connecting plates, so that fasteners of different sizes can be covered on the periphery of the connecting plate or inserted into the inner periphery of the connecting plate, so that the device can adapt to fasteners of different outer diameters or inner diameters to improve the applicability of the device, and secondly, the first motor drives the driving sleeve to rotate, so that friction occurs between the four groups of connecting plates and the fasteners, so as to achieve the purpose of deburring the fasteners.
