Technical Field

[0001] This utility model relates to the field of bolt processing equipment technology, specifically to a chamfering machine for preparing anti-loosening bolts. Background Technology

[0002] A bolt is a mechanical part, a type of fastener consisting of a head and a shank (a cylinder with external threads). It needs to be used with a nut to fasten two parts with through holes. Bolts typically require chamfering during manufacturing, necessitating the use of a specialized chamfering machine.

[0003] However, existing chamfering machines for preparing anti-loosening bolts require manual clamping of the bolts before adjusting them to move into the chamfering barrel. This is time-consuming and labor-intensive, reducing the processing efficiency of the bolts and making them impractical. Therefore, this invention provides a chamfering machine for preparing anti-loosening bolts. Utility Model Content

[0025] Example 1

[0026] like Figures 1-5 As shown, this embodiment proposes a chamfering machine for preparing anti-loosening bolts, including a base plate 1, a base 3 and an inverted U-shaped frame 5. A supporting vertical plate 2 is symmetrically fixedly installed on the top of the base plate 1. A drive motor 4 is fixedly installed on the top of the base 3. A chamfering cutter cylinder 6 is fixedly installed at the output end of the drive motor 4. An automatic positioning component 100 is provided on the inverted U-shaped frame 5. An automatic feeding component 200 is provided on the top of the base plate 1.

[0027] In detail, the input end of the drive motor 4 is connected to the power supply through an external cable. The drive motor 4 is located on one side of the inverted U-shaped frame 5, and the inverted U-shaped frame 5 is located on one side of the two supporting vertical plates 2.

[0028] The automatic positioning assembly 100 includes an electric push rod 101, a connecting crossbar 102, and a pressing mold 103. The pressing mold 103 matches the outer surface of the bolt. The output end of the electric push rod 101 extends movably through to the bottom of the inverted U-shaped frame 5 and is fixedly installed with the connecting crossbar 102. Two pressing molds 103 are fixedly installed at the lower end of the connecting crossbar 102. An elongated groove 106 is provided on one side of the inverted U-shaped frame 5. One end of the connecting crossbar 102 extends movably through to one side of the elongated groove 106 and is fixedly installed with the connecting crossbar 102. A trapezoidal slider 104 is fixedly installed, with the inclined side of the trapezoidal slider 104 located on one side of the bottom. A sleeve rod 105 is fixedly installed on the inner side of the inverted U-shaped frame 5 at the bottom of the elongated groove 106. A sliding rod 108 slides through the sleeve rod 105 and the inverted U-shaped frame 5. A limit plate 109 is fixedly installed on the outer surface of the sliding rod 108 inside the sleeve rod 105. A spring 110 is fixedly installed between the limit plate 109 and the sleeve rod 105. A rolling wheel 107 is fixedly installed at one end of the sliding rod 108.

[0029] The hypotenuse of the trapezoidal slider 104 is on the same vertical plane as one side of the rolling wheel 107. The spring 110 is sleeved on the outer surface of the sliding rod 108. One end of the sliding rod 108 is on the same horizontal plane as one end of the first bolt.

[0030] The side wall of the connecting crossbar 102 matches the side wall of the elongated groove 106, and the limiting plate 109 matches the inner side wall of the sleeve 105.

[0031] A T-shaped slider 111 is fixedly installed at one end of the connecting crossbar 102. A T-shaped groove 112 matching the T-shaped slider 111 is opened on the side wall of the inverted U-shaped frame 5. Through the cooperation of the T-shaped slider 111 and the T-shaped groove 112, the connecting crossbar 102 can move up and down stably.

[0032] In detail, the input end of the electric push rod 101 is connected to the power supply through an external cable. The two pressing molds 103 match the outer surface of the thread, and the bottom of the two pressing molds 103 is directly opposite the top of the first bolt at the top of the supporting vertical plate 2. When the pressing molds 103 move away from the bolt, the sliding rod 108 moves away from the bolt end through the reset action of the spring 110.

[0033] Example 2

[0034] like Figures 1-5As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes an automatic feeding assembly 200 including a feeding rack 201, two protective shells 202 and an electric push rod 203. T-shaped slide bars 204 are symmetrically fixedly installed on both sides of the bottom of the base plate 1. T-shaped slide grooves 205 are symmetrically fixedly installed on the bottom of the two protective shells 202. The T-shaped slide grooves 205 match the T-shaped slide bars 204. The electric push rod 203 is fixedly installed inside the two protective shells 202. Telescopic rods 206 are fixedly installed on both sides of the electric push rod 203 inside the two protective shells 202. The output ends of the protective shells 202 and the telescopic rods 206 are fixedly installed at the bottom of the feeding rack 201. The electric push rod 307 is fixedly installed at the bottom of the base plate 1. The output end of the electric push rod 307 is fixedly installed on one side of the protective shell 202.

[0035] The top of the feeding rack 201 and the top of the supporting vertical plate 2 are evenly provided with placement slots. The distance between each placement slot on the feeding rack 201 is the same as the distance between each placement slot on the supporting vertical plate 2. Bolts are placed in the placement slots.

[0036] A through groove 7 matching the chamfered cutter barrel 6 is provided on one side of the inverted U-shaped frame 5, and guide rods 8 are fixedly installed on one side of each of the two support vertical plates 2;

[0037] In detail, the input ends of electric push rod 203 and electric push rod 307 are connected to the power supply via external cables. By starting electric push rod 203, the feeding rack 201 is moved upward, thereby pushing the bolts in the placement slots on the support vertical plate 2 into the placement slots on the feeding rack 201. Then, electric push rod 307 is started to push the protective shell 202 forward a fixed distance. Then, electric push rod 203 drives the feeding rack 201 downward, and the bolts in the placement slots on the feeding rack 201 fall into the previous placement slot on the support vertical plate 2, thus facilitating the sequential and equidistant movement of the bolts forward.

[0038] During operation, the bolts are first placed sequentially in the slots on the support vertical plate 2, with the inner side of the bolt head against the outer side of the support vertical plate 2. Then, the electric push rod 203 is activated to move the feeding frame 201 upward, thereby pushing the bolts in the slots on the support vertical plate 2 into the slots on the feeding frame 201. Next, the electric push rod 207 is activated to push the protective shell 202 forward a fixed distance. Then, the electric push rod 203 drives the feeding frame 201 downward, and the bolts in the slots on the feeding frame 201 fall into the slots of the support vertical plate 2. When the first bolt is placed in the slot and is delivered to the bottom of the pressing mold 103, the electric push rod 101 is activated to drive the pressing mold 103 at the bottom of the connecting crossbar 102 to press and fix the bolt. As the connecting crossbar 102 moves downward, the trapezoidal slider 104 pushes the sliding rod 108 at one end of the rolling wheel 107 towards the bolt end through the inclined side at the bottom. The sliding rod 108 pushes the bolt head into the chamfering barrel 6. Then, the drive motor 4 is activated to drive the chamfering barrel 6 to rotate, thereby completing the chamfering operation.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
