DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1: Figure 1-Figure 7 As shown, a stainless steel fastening bolt processing chamfering device is provided, including a base cabinet 1, a feeder is arranged on the upper end of the base cabinet 1, and the stainless steel fastening bolts to be processed are fed one by one through the feeder. The feeder can adopt a vibration plate 2, and a slide plate 4 located at the left end of the outlet of the feeder and arranged with a left lower and right higher tilt and extending from the left side of the base cabinet 1 is installed on the upper side of the base cabinet 1. The stainless steel fastening bolt slides to the left through the slide plate 4, and then two trapezoidal support plates 3 with a left narrow and right wide cross section are symmetrically installed between the upper end of the base cabinet 1 and the slide plate 4. The two support plates 3 are used in combination to lift the slide plate 4;

[0032] A through slot 45 is formed on the upper end surface of the slide plate 4, which penetrates the slide plate 4 and extends to the left end of the slide plate 4 and is located between the two support plates 3. The rod of the stainless steel fastening bolt is moved to the lower side of the slide plate 4 through the through slot 45. A frame 5 which is perpendicular to the slide plate 4 and has an inverted U-shaped cross section and two vertical portions are respectively located at the front and rear sides of the through slot 45 is installed on the upper end of the slide plate 4. Through the frame 5, a mounting carrier is provided for the first lifting device and other components, and the fixing portion of the first lifting device is set on the top of the inner part of the frame 5. Through the first lifting device, the movable plate 52 is driven to move up and down. The first lifting device can use a first electric push rod 51;

[0033] The movable plate 52 which is slidably connected in the frame 5 and has an L-shaped cross section is installed on the lower end of the movable part of the first lifting device. The movable plate 52 is used to provide a mounting carrier for the positioning cylinder 53 on the one hand, and to limit the sliding stainless steel fastening bolts on the other hand. The positioning cylinder 53 with the opening facing downward is arranged on the middle part of the lower end of the movable plate 52. The nut part of the stainless steel fastening bolt is limited by the positioning cylinder 53. The upper end surface of the slide plate 4 is recessed downward to form a slot 401 which penetrates the slide plate 4 and the through groove 45 and is in a cross state with the through groove 45 and is located directly below the vertical part of the movable plate 52. Through the slot 401, the vertical part of the movable plate 52 penetrates the slide plate 4.

[0034] The fixed part of the second lifting device arranged with the left side higher and the right side lower tilted is arranged on the upper end of the base cabinet 1, and the driving device is moved up and down by the second lifting device, and the fixed part of the driving device located between the two support plates 3 is installed on the upper end of the movable part of the second lifting device. The processing cylinder 61 is driven to rotate by the driving device, and then four telescopic rods 65 located on the outside of the second lifting device and the other end of which is connected to the upper end of the base cabinet 1 are respectively installed at the four corner positions of the lower end of the driving device. The four telescopic rods 65 are used in combination to guide the up and down movement of the driving device, and the processing cylinder 61 located directly below the positioning cylinder 53 and arranged with the opening facing upward is arranged on the upper end of the output shaft of the driving device, and the stainless steel fastening bolts are chamfered by the processing cylinder 61;

[0035] The housing 44 is arranged on the upper side of the slide plate 4, and the housing 44 is used to provide installation space for components such as the electromagnet 46, and two straight plates 42 located at the front and rear sides of the through slot 45 and respectively installed at the right ends of the two vertical parts of the frame 5 are symmetrically installed between the housing 44 and the slide plate 4. The two straight plates 42 are used in combination to limit and guide the sliding stainless steel fastening bolts, and then two guide plates 41 with a V-shaped structure arranged with a narrow left and a wide right are respectively arranged on the right ends of the two straight plates 42, and the two guide plates 41 are used in combination to guide the stainless steel fastening bolts;

[0036] The horizontal part of a limit plate 43 with a T-shaped cross section and a vertical lower end passing through the housing 44 and in contact with the upper end of the slide plate 4 and a vertical portion located between the two straight plates 42 is slidably connected inside the housing 44. The limit plate 43 is used to limit the sliding stainless steel fastening bolts on the slide plate 4, and an electromagnet 46 located between the two round rods 47 is set on the top of the inner part of the housing 44. Then, a magnetic strip 48 located directly below the electromagnet 46 and mutually repelling with the electromagnet 46 and located between the two round rods 47 is installed on the upper end of the limit plate 43. The electromagnet 46 and the magnetic strip 48 are used in conjunction with each other to move the limit plate 43 downward.

[0037] Two round rods 47 that penetrate the transverse part of the limit plate 43 and are slidably connected to the limit plate 43 are symmetrically arranged inside the shell 44. The two round rods 47 are used together to guide the movement of the limit plate 43, and two second elastic members 49 located on the outside of the two round rods 47 are symmetrically installed between the lower end of the transverse part of the limit plate 43 and the bottom end of the shell 44. The two second elastic members 49 are used together to return the limit plate 43 to its original position. The second elastic member 49 can be a spring.

[0038] When in use, a large number of stainless steel fastening bolts to be processed are first put into the vibration plate 2, and then the vibration plate 2 is started, so that the stainless steel fastening bolts are transported one by one to the upper end of the slide plate 4 by the vibration plate 2. Because the slide plate 4 is arranged with the left side lower and the right side higher, the stainless steel fastening bolts will slide to the lower left along the slide plate 4. At the same time, the two guide plates 41 cooperate to move the sliding stainless steel fastening bolts to between the two straight plates 42, and the stainless steel fastening bolts are located at the upper end of the through groove 45. At this time, the rod of the stainless steel fastening bolt will pass through the through groove 45, and the nut of the stainless steel fastening bolt is restricted at the upper end of the slide plate 4, so as to realize the automatic position correction operation of the stainless steel fastening bolts, effectively reduce the labor intensity and working time, and effectively ensure the chamfering effect and work efficiency of the stainless steel fastening bolts.

[0039] After the correction, the stainless steel fastening bolt still slides toward the lower left along the slide plate 4. When the nut portion of the stainless steel fastening bolt contacts the limit plate 43, the circuit of the electromagnet 46 is disconnected, and under the elastic force of the second elastic member 49, the limit plate 43 moves upward along the shell 44, thereby releasing the limit on the stainless steel fastening bolt. Then the stainless steel fastening bolt continues to slide toward the lower left along the slide plate 4, and uses the vertical portion of the movable plate 52 to limit the stainless steel fastening bolt again. Then the circuit of the electromagnet 46 is connected again. Because the electromagnet 46 and the magnetic strip 48 are arranged to repel each other, a repulsive force is generated between the electromagnet 46 and the magnetic strip 48. Under the action of the repulsive force, the limit plate 43 moves downward again and contacts the upper end of the slide plate 4, and compresses the two second elastic members 49, so that the second elastic members 49 generate elastic force, thereby limiting the subsequent stainless steel fastening bolts.

[0040] Then, the first electric push rod 51 is started, thereby driving the movable plate 52 to move downward, and then the positioning cylinder 53 is moved downward, so that the nut portion of the stainless steel fastening bolt is stuck in the positioning cylinder 53, and then the stainless steel fastening bolt is pressed and positioned, and then the second electric push rod 62 is started, thereby driving the servo motor 6 and the processing cylinder 61 to move upward, and then the lower end of the rod of the stainless steel fastening bolt is inserted into the processing cylinder 61, and at the same time, the servo motor 6 is started, thereby driving the processing cylinder 61 to rotate, and then the stainless steel fastening bolt is chamfered by the rotating processing cylinder 61;

[0041] After chamfering is completed, the second electric push rod 62 is first used to move the servo motor 6 and the processing cylinder 61 downward and return to their original positions, and then the first electric push rod 51 is used to move the movable plate 52 and the positioning cylinder 53 upward and reach the limit position, thereby releasing the restriction on the stainless steel fastening bolts, and then the processed stainless steel fastening bolts continue to slide to the lower left along the slide plate 4, thereby discharging the processed stainless steel fastening bolts, and then the first electric push rod 51 is used to move the movable plate 52 and the positioning cylinder 53 downward, so that the vertical part of the movable plate 52 moves to the upper end of the slot 401, and then the subsequent stainless steel fastening bolts are limited again, thereby realizing mechanical continuous chamfering of the stainless steel fastening bolts, effectively reducing the probability of processing defects in the chamfering position due to factors such as manual operation, effectively reducing labor intensity and working time, improving work efficiency, and effectively ensuring the chamfering effect of the stainless steel fastening bolts.

[0042] Embodiment 2: Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the mounting plate 64 is arranged on the outer end of the processing cylinder 61, and the mounting plate 64 is used to provide a mounting carrier for the protruding block 63, and the protruding block 63 is installed on the upper end of the mounting plate 64, and the U-shaped rod 402 is moved upward through the protruding block 63, and then the two vertical parts of the U-shaped rod 402 located just above the mounting plate 64 are both arranged on the lower end of the slide plate 4, and the slide plate 4 is moved upward through the U-shaped rod 402, and a plurality of concave holes 31 are formed on the upper end surface of the support plate 3, and the concave holes 31 are used to provide installation space for components such as T-shaped columns 32, and then a plurality of rod parts are extended out of the upper side of the concave holes 31 and the T-shaped columns 32 connected to the lower end of the slide plate 4 are respectively slidably connected in the plurality of concave holes 31, and the movement of the slide plate 4 is guided through the T-shaped columns 32;

[0043] The inner wall surface of the recessed hole 31 is recessed outward to form an installation groove, and the installation groove is used to provide installation space for the limit piece. The limit piece located on the outer side of the rod portion of the T-shaped column 32 is assembled into the installation groove, and the installation between the annular plate 34 and the recessed hole 31 is restricted by the limit piece. The limit piece can adopt a retaining spring 35, and the annular plate 34 slidably connected to the outer end of the rod portion of the T-shaped column 32 is fitted on the lower end of the limit piece. The first elastic piece 33 is limited by the annular plate 34, and then the first elastic piece 33 located on the outer side of the rod portion of the T-shaped column 32 is set between the lower end of the annular plate 34 and the upper end of the transverse portion of the T-shaped column 32. The T-shaped column 32 can be moved downward along the recessed hole 31 by the first elastic piece 33, and the first elastic piece 33 can adopt a spring.

[0044] When in use, the stainless steel fastening bolts are pressed and positioned by the first electric push rod 51, the movable plate 52 and the positioning cylinder 53, and then the servo motor 6 and the processing cylinder 61 are moved upward by the second electric push rod 62, and the stainless steel fastening bolts are chamfered by the servo motor 6 and the processing cylinder 61. When the processing cylinder 61 moves to the processing position, the lower end of the U-shaped rod 402 and the upper end of the mounting plate 64 are in contact with each other, and at this time the positioning cylinder 53 is in a rotating state, thereby rotating the mounting plate 64 and causing the raised block 63 to rotate;

[0045] When the raised block 63 contacts the U-shaped rod 402, the U-shaped rod 402 will move upward, and then the multiple T-shaped columns 32 will extend the multiple recessed holes 31 and move upward, thereby compressing the multiple first elastic members 33, causing the first elastic members 33 to generate elastic force. When the raised block 63 separates from the U-shaped rod 402, the T-shaped column 32 will extend the recessed holes 31 downward under the elastic force of the first elastic member 33, thereby driving the slide plate 4 to vibrate up and down in a cycle, effectively reducing the probability of stainless steel fastening bolts getting stuck on the slide plate 4 due to burrs and other factors, effectively ensuring the chamfering effect and work efficiency of the stainless steel fastening bolts, and achieving linkage between vibration movement and processing movement.

[0046] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
