[0025] refer to Figure 1-4 As shown, this utility model provides a riveting bolt processing device, including a frame 1, a motor 2, a transmission box 3, a transmission mechanism 4, a drilling assembly 5, a propulsion mechanism 6, and a clamping mechanism 7.

[0026] The frame 1 has a table-type structure. The frame 1 mainly serves to support other components. The lower ends of the four corner support legs of the frame 1 can be equipped with adjustable feet 11. The adjustable feet 11 are threadedly connected to the support legs of the frame 1, which makes it easy to adjust the stability of the frame 1 when placed on the ground.

[0027] The transmission box 3 includes a vertical transmission box 31 and a horizontal transmission box 32. The vertical transmission box 31 and the horizontal transmission box 32 form an L-shaped structure, with the vertical transmission box 31 located at the rear end of the horizontal transmission box 32.

[0028] The motor 2 is located on the upper front side of the vertical transmission box 31.

[0029] The transmission mechanism 4 includes a first transmission wheel 41, a second transmission wheel 42, a third transmission wheel 43, a fourth transmission wheel 44, and a transmission shaft 45. The transmission shaft 45 is rotatably supported in the transverse transmission box 32. The first transmission wheel 41 is mounted on the output shaft of the motor 2 and can rotate synchronously. The second transmission wheel 42 is mounted on the rear end of the transmission shaft 45 and can rotate synchronously. The first transmission wheel 41 and the second transmission wheel 42 are connected by a first transmission belt 46. The third transmission wheel 43 is mounted on the front end of the transmission shaft 45 and can rotate synchronously.

[0030] The drilling assembly 5 includes a sleeve 51, a spindle 52, a chuck 53, a drill bit 54, and a return spring 55. The sleeve 51 is slidably disposed within the transverse transmission box 32. The spindle 52 is supported within the sleeve 51 by bearings. The spindle 52 can rotate relative to the sleeve 51 and can also move synchronously with the sleeve 51 along the axis. Both ends of the spindle 52 extend out of the transverse transmission box 32. The chuck 53 is disposed at the front end of the spindle 52, and the drill bit 54 is held by the chuck 53. The return spring 55 is disposed on the side wall of the transverse transmission box 32 and connected to the sleeve 51. The fourth transmission wheel 44 of the transmission mechanism 4 is disposed on the spindle 52. The third transmission wheel 43 and the fourth transmission wheel 44 are connected by a second transmission belt 47. The spindle 52 can also slide relative to the fourth transmission wheel 44 along the axial direction.

[0031] Motor 2 can drive the first transmission wheel 41 to rotate, which in turn drives the second transmission wheel 42 to rotate via the first transmission belt 46. The transmission shaft 45 rotates synchronously with the second transmission wheel 42, driving the third transmission wheel to rotate. Then, the fourth transmission wheel 44 is driven to rotate via the second transmission belt 47, thereby driving the spindle 52 to rotate. Its working principle is the same as that of the existing bench drill.

[0032] The propulsion mechanism 6 includes a first cylinder 61, a pusher head 62, a displacement rod 63, and a limit sensor 64. The first cylinder 61 is mounted on the transverse transmission box 32, with its extension rod facing the main shaft 52. The pusher head 62 is located at the front end of the extension rod of the first cylinder 61, and a push rod 65 is provided at the front end of the pusher head 62. A top cap 66 is provided at the front end of the push rod 65, and the top cap 66 rotatably engages with the push rod 65. The displacement rod 63 is located on one side of the pusher head 62, and the limit sensor 64 is mounted on the transverse transmission box 32 and corresponds to the displacement rod 63. When the extension rod of the first cylinder 61 extends, it drives the pusher head 62 to move forward. Then, the top cap 66 presses against the rear end of the main shaft 52, and the extension rod of the first cylinder 61 continues to extend, thereby pushing the main shaft 52 to slide forward and driving the drill bit 54 to move forward. In this embodiment, the top cap 66 and the top rod 65 are rotatably engaged. In this way, when the top cap 66 presses against the main shaft 52, the top cap 66 rotates with the main shaft 52, which can greatly reduce the friction between the main shaft 52 and the top cap 66 and reduce wear.

[0033] The clamping mechanism 7 includes a support base 71, a clamp 72, and a second cylinder 73. The support base 71 is mounted on the frame 1 and located in front of the propulsion mechanism 6. The clamp 72 is mounted on the support base 71, and the upper end of the clamp 72 is provided with a workpiece slot 721, which corresponds to the drill bit 54. The second cylinder 73 is mounted on the support base 71 and located above the clamp 72. The extension rod of the second cylinder 73 faces downward, and the lower end of the extension rod of the second cylinder 73 is provided with a pressure plate 74. The second cylinder 73 can drive the pressure plate 74 to move downward and press it against the upper end of the clamp 72, thereby pressing the workpiece in the workpiece slot 721 to facilitate processing.

[0034] The first cylinder 61 and the second cylinder 73 are connected to the air compressor via air pipes, which allows the cylinders to extend and retract.

[0035] The operation method of the riveting bolt processing device provided in this embodiment of the utility model is as follows:

[0036] First, place the front end of the bolt to be processed into the workpiece slot 721 on the fixture 72. The motor 2 drives the drill bit 54 to rotate. Then, the second cylinder 73 drives the pressure plate 74 to move down and press the workpiece. Then, the first cylinder 61 works, and the telescopic rod of the first cylinder 61 extends forward, driving the pusher 62 to move forward. Then, the top cap 66 presses against the rear end of the spindle 52. The telescopic rod of the first cylinder 61 continues to extend, thereby pushing the spindle 52 to slide forward and driving the drill bit 54 to move forward, thus drilling a hole in the front end of the bolt. The drilling depth is controlled by the limit sensor 64. After drilling is completed, the telescopic rod of the first cylinder 61 retracts, driving the pusher 62 to move backward and separate from the spindle 52. The spindle 52 moves backward under the action of the return spring 55, thereby separating the drill bit 54 from the drilled bolt. Finally, the telescopic rod of the second cylinder 73 retracts, driving the pressure plate 74 to move up, and the processed bolt can be removed.

[0037] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
