[0002] Bolts are a type of fastener consisting of a head and a screw, used to fasten two parts with through holes. After the existing bolts are manufactured through the thread rolling process, there are inevitably a small amount of burrs on the bolts. During the use of customers, such burrs will inevitably pierce the skin of the palm, affecting the customer's experience and even affecting the accuracy of subsequent use. Therefore, it is necessary to deburr the surface of the bolts in a timely manner.

[0003] For example, the Chinese utility model patent with patent number 202022003225.6 provides a bolt deburring device. When the device is in use, the staff places batches of bolts and corundum into a mixing barrel. The motor drives the mixing barrel to rotate. At the same time, the hydraulic oil rod pushes and pulls the left push rod, so that the mixing barrel can swing left and right while rotating, effectively enhancing the irregular movement of the bolts in the mixing barrel and removing the burrs through the friction generated by the corundum.

[0004] However, most of the existing bolt end deburring devices perform batch deburring of bolts by pouring the bolts into a mixing barrel containing fine steel grit for stirring. This method is time-consuming and laborious when taking the bolts out of the fine steel grit pile, and the fine steel grit is easily brought out to the next-level processing machine, affecting subsequent processing. Utility Model Content

[0011] In a preferred embodiment, the connecting cylinder is hinged at the end of the connecting seat, and the connecting seat and the connecting cylinder are connected via a connecting assembly to drive the connecting cylinder to rotate along a hinge point between the connecting cylinder and the connecting seat.

[0012] In a preferred embodiment, the connecting assembly includes a telescopic rod, and two ends of the telescopic rod are respectively hinged to the connecting seat and the connecting tube.

[0013] In a preferred embodiment, a slide groove is provided on the mounting plate, and a threaded column connected through a limiting plate is provided at one end of the receiving frame. The threaded column is slidably clamped in the slide groove and is threadedly connected with a limiting nut.

[0028] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0029] Example:

[0030] like Figure 1 , 3 As shown, the utility model provides a bolt end deburring device, which is installed on a three-dimensional gantry for use, and includes a movable rod 101 arranged on the three-dimensional gantry. The movable rod 101 can be driven to rise and fall and translate on a two-dimensional plane through the three-dimensional gantry, so that the movable rod 101 can be conveniently moved between a mixing barrel and its upper and lower processes. A driving motor 102 is arranged at the end of the movable rod 101, and a connecting seat 103 is arranged on the output shaft of the driving motor 102. The connecting seat 103 can be driven to rotate by controlling the start of the driving motor 102.

[0031] like Figure 1 , 3 As shown, in this embodiment, a connecting tube 104 is provided at one end of the connecting seat 103, a mounting plate 106 is provided at the end of the connecting tube 104, a telescopic motor 201 is provided in the connecting tube 104, and a pressure plate 202 is provided at the output end of the telescopic motor 201. The device also includes multiple groups of receiving frames 401, one end of the receiving frame 401 is connected to the mounting plate 106, and the pressure plate 202 is located on the inner side of the receiving frame 401. Each adjacent two groups of receiving frames 401 form a gap to accommodate the end of the bolt, and the gap is smaller than the bolt head.

[0032] The bolts can be placed between multiple groups of receiving frames 401, and the gaps between the receiving frames 401 are used to support the bolt heads, and the ends of the bolts are extended to the receiving frames 401. Then, the telescopic motor 201 is controlled to start and drive the pressing plate 202 to move downward until the pressing plate 202 abuts against the bolt heads, thereby fixing the bolts and preventing the bolts from falling into the steel sand pile during the deburring process. Finally, the connecting seat 103 is driven to rotate by the driving motor 102, so that the bolts move circumferentially in the steel sand pile, and the bolt ends are deburred by the diamond sand.

[0033] like Figure 3 As shown, in this embodiment, the connecting cylinder 104 is hinged at the end of the connecting seat 103, and the connecting seat 103 and the connecting cylinder 104 are connected through a connecting assembly to drive the connecting cylinder 104 to rotate along the hinge point between the connecting cylinder 104 and the connecting seat 103. The connecting assembly includes a telescopic rod 105, and the two ends of the telescopic rod 105 are respectively hinged to the connecting seat 103 and the connecting cylinder 104. A cavity for the bolt to be placed is provided between the other end of the receiving frame 401 and the mounting plate 106.

[0034] In the process of removing the bolts from the multiple groups of receiving frames 401, the telescopic rod 105 can be controlled to extend to drive the connecting tube 104 to rotate along the hinge point between it and the connecting seat 103, so that the receiving frame 401 is tilted as a whole, so that the bolts on the receiving frame 401 can fall off by their own gravity, making the removal of the bolts more time-saving and labor-saving.

[0035] like Figure 2 , 3 As shown, in this embodiment, a slide groove 107 is provided on the mounting plate 106, and a threaded column 403 connected through a limiting plate 402 is provided at one end of the receiving frame 401. The threaded column 403 is slidably clamped in the slide groove 107 and is threadedly connected with a limiting nut 404. The threaded column 403 can be slid in the slide groove 107 after loosening the limiting nut 404, so as to adjust the gap between multiple groups of receiving frames 401, and facilitate deburring of bolts of different sizes.

[0036] like Figure 3 As shown, in this embodiment, a plurality of groups of abutment columns 203 are arranged at the bottom of the pressing plate 202, and the bolt head can be abutted by the abutment columns 203, thereby reducing the shielding area of ​​the bolt head and increasing the range of deburring, which effectively improves the practical value of the device. A limiting column 301 is arranged at the bottom of the mounting plate 106, and a buffer pad 302 that can abut against the pressing plate 202 is arranged at the bottom of the limiting column 301. The arrangement of the cylinder limiting column 301 can prevent the pressing plate 202 from hitting the receiving frame 401 when it is retracted, and the movement of the pressing plate 202 is buffered by the buffer pad 302, thereby improving the service life of the device.

[0037] Specific usage and beneficial effects of the utility model:

[0038] When the device is in use, it is installed on a three-dimensional gantry, and the three-dimensional gantry is used to control the movement and lifting of the movable rod 101, so as to facilitate the transfer of the bolts to a barrel containing fine steel sand or to move them out to the next level processing area. The heads of the bolts are supported by the gaps between the multiple groups of receiving frames 401, so that the multiple groups of bolt ends are arranged downward, and then the telescopic motor 201 is controlled to start and drive the pressure plate 202 to move downward to press the heads of the bolts to prevent the bolts from detaching from the receiving frame 401 during the deburring process. Then, the starting motor is controlled to start and drive the connecting seat 103 to rotate, so that the multiple groups of bolts move in the corundum, and the burrs on the bolt ends are removed by the friction of the corundum. After the processing is completed, the movable rod 101 is controlled to rise by the three-dimensional gantry, so as to facilitate the simultaneous removal of the multiple groups of bolts from the corundum pile, and then the pressure plate 202 is driven to move upward to complete the removal of the bolts. When in use, the device can conveniently and quickly remove the bolts to the subsequent processing area, and will not bring the diamond abrasives into the next-level processing machinery, avoiding affecting the subsequent processing, effectively improving the processing efficiency and reducing the labor intensity of the staff.
