[0022] Preferably, the sliding strip and the pressure strip have matching concave-convex patterns on opposite sides of the surface.

[0023] A method for using a parts grinding device for automobile parts processing comprises the following steps:

[0024] S1. Start the motor to drive the grinding belt wheel to rotate, so that the grinding belt runs in the frame. At this time, the operator can put the auto parts on the grinding table, push them to the grinding port, and grind them with the grinding belt;

[0025] S2. During the operation of the grinding belt, compressed gas is input into the cylinder through the hose using an external joint, so that the air nozzle sprays air toward the taut grinding belt and generates a reverse thrust along the grinding belt, causing the cylinder compression spring to move forward. When the grinding belt breaks, the reverse thrust of the air nozzle is insufficient, and the spring pushes the cylinder backward, driving the sliding clamp to move synchronously, and constraining along the broken edge of the grinding belt;

[0026] S3, when the grinding belt breaks and the sliding clamp moves, the sliding clamp pushes the pressure strip toward the slide bar, so that the through nail passes through the grinding belt and then inserts into the through hole for reverse locking, thereby controlling the slide bar and the pressure strip to be fixed along the broken edge of the grinding belt, and using the metal rope between the upper and lower slide bars to link the broken area of ​​the grinding belt, at this time, the grinding belt can bring the upper and lower slide bars out of the slide groove and the lower slide groove upward, so that the grinding belt continues to run;

[0027] S4. When the lower slide bar slides upward from the lower slide groove, the gear inside it is rotated by the rack belt, and then drives another gear to rotate, so that it pushes the sliding pin along the tooth surface and moves down along the socket. At this time, the metal rope between the two slide bars is pulled shorter and the two broken ends of the grinding belt are relatively close.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] In the present invention, air is sprayed toward the taut grinding belt through the air nozzle, and reverse thrust is generated along the grinding belt, so that the cylinder compresses the spring to move forward. When the grinding belt breaks, the reverse thrust of the air nozzle is insufficient, the spring pushes the cylinder to move backward, and drives the sliding clamp to move synchronously to constrain along the broken end of the grinding belt. Compared with the existing method of using a limiting roller to make physical contact with the grinding belt, the above-mentioned cylinder and the air nozzle cooperate to form a pneumatic structure of airflow reverse thrust, and use the airflow to monitor the grinding belt, which ensures the function of constraining the broken grinding belt while avoiding vibration, wear and the like caused by the grinding belt contacting the physical structure.

[0030] In the present invention, the pressure strip is pushed toward the slide bar by means of sliding pliers, so that the nail is inserted into the through hole after passing through the grinding belt to be locked, so as to control the sliding bar and the pressure strip to be fixed along the broken end of the grinding belt, and the broken area of ​​the grinding belt is linked by means of the metal rope between the upper and lower sliding bars, so that the grinding belt continues to run. Compared with the existing method of squeezing and fixing the broken end of the grinding belt, the above-mentioned sliding bar and the metal rope can cooperate to form a linking structure, and then the pressure strip is used to fix it along the grinding belt, so as to link the broken end of the grinding belt by means of the linking structure. On the one hand, the grinding belt can continue to run in an emergency, avoiding the pulling and breaking of other positions caused by squeezing the grinding belt, and on the other hand, it can avoid the broken grinding belt being involved in the internal transmission structure to cause safety hazards.

[0031] In the present invention, the gear inside the lower sliding bar is rotated by the rack belt, and then drives another gear to rotate, so that it pushes the sliding pin along the tooth surface to move downward along the socket. At this time, the metal rope between the two sliding bars is pulled shorter, and the two broken ends of the grinding belt are relatively drawn closer, so that the broken grinding belt is tightened and continues to be stably mounted on the two grinding belt wheels, which can effectively prevent the grinding belt from detaching from the grinding belt wheel after it is broken, and can ensure the emergency operation of the grinding belt in the connected state.

[0050] The frame 1 and the upper clamping seat 89 and the lower clamping seat 810 are provided with a linking assembly 811 that matches the grinding belt 5 .

[0051] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11As shown, the link assembly 811 includes two groups of slides 8111 fixedly arranged inside the frame 1, and the two groups of slides 8111 are distributed on the upper and lower sides of the grinding port 7 and correspond to the sliding clamps 88 on both sides respectively. The slide 8111 is located between the grinding belt 5 and the sliding clamp 88, and a pressure strip 8112 controlled by the sliding clamp 88 on the same side is slidably connected in the single group of slides 8111.

[0052] An upper slide groove 8113 is provided on the side surface of the upper clamping seat 89, and a lower slide groove 8114 is provided on the side surface of the lower clamping seat 810, and a slide bar 8115 is slidably connected in the lower slide groove 8114 and the upper slide groove 8113. When the grinding belt 5 breaks and the sliding clamp 88 moves, the sliding clamp 88 pushes the pressure bar 8112 toward the slide bar 8115, and the two slide bars 8115 are fixedly connected by two metal ropes 8116, and two through nails 8117 cooperating with the grinding belt 5 are fixedly provided on the surface of the slide bar 8115.

[0053] A through hole 8118 matching with the through nail 8117 is provided on the surface of the pressure strip 8112, and an annular groove 8119 is provided on the surface of the through nail 8117. A conical inverted clamp 81110 matching with the annular groove 8119 is provided at the opening of the through hole 8118. When the pressure strip 8112 is pushed toward the slide bar 8115, the through nail 8117 pierces the grinding belt 5 and is inserted into the through hole 8118 for inverted locking, so as to control the slide bar 8115 and the pressure strip 8112 to be fixed along the fracture of the grinding belt 5, and the metal rope 8116 between the upper and lower slide bars 8115 is used to link the fracture area of ​​the grinding belt 5. At this time, the grinding belt 5 can bring the upper and lower slide bars 8115 upward out of the slide groove and the lower slide groove 8114, so that the grinding belt 5 continues to run.

[0054] A tightening assembly 81111 is provided on the metal rope 8116 , the lower sliding bar 8115 and the lower sliding groove 8114 .

[0055] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, the tightening assembly 81111 includes a rack 811111 fixedly arranged on the side wall of the lower sliding groove 8114, both ends of the lower sliding bar 8115 are provided with vertical grooves 811112 matching the rack 811111 on the same side, and both ends of the lower sliding bar 8115 are provided with sockets 811113 corresponding to the metal rope 8116, and a sliding pin 811114 is slidably connected in the socket 811113, and the top of the sliding pin 811114 is fixedly connected to the metal rope 8116.

[0056] The side surface of the sliding pin 811114 is provided with a tooth surface 811115 .

[0057] An inner groove 811116 connected to the vertical groove 811112 and the socket 811113 is provided at the end of the lower slide bar 8115, and two mutually meshing gears 811117 are rotatably connected in the inner groove 811116. The two gears 811117 are respectively meshed with the tooth surface 811115 and the rack 811111. When the lower slide bar 8115 slides upward from the lower slide groove 8114, the gear 811117 inside it is rotated by the rack 811111, and then the other gear 811117 is driven to rotate, so that the sliding pin 811114 is pushed down along the socket along the tooth surface 811115. At this time, the metal rope 8116 between the two slide bars 8115 is pulled shorter, and the two fractures of the grinding belt 5 are relatively brought closer.

[0058] A one-way bearing 811118 is provided on the gear 811117, and the one-way bearing 811118 prevents the gear 811117 from rotating, that is, the sliding pin 811114 cannot move upward along the insertion hole 811113.

[0059] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, a suction duct is fixedly installed on the back of the frame 1. When the air nozzle 84 performs air jet monitoring, it is easy to cause grinding debris to be dispersed in the frame 1. The suction duct can extract it in real time to ensure the smooth progress of the grinding work.

[0060] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, a ring seat is provided at the root of the conical reverse clamp 81110, and the ring seat is fixedly mounted on the slide bar 8115 by screws. The conical reverse clamp 81110 can be completely disassembled through the ring seat by unscrewing the screws, so that the operator can replace the conical reverse clamp 81110 with degraded reverse locking performance conveniently.

[0061] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, a threaded hole corresponding to the through-pin 8117 is formed on the side surface of the slide bar 8115, and the through-pin 8117 is screwed into the threaded hole. The threaded structure allows the through-pin 8117 to be quickly disassembled and assembled along the slide bar 8115, so that the user can replace the worn through-pin 8117 in time, thereby ensuring that the through-pin 8117 stably penetrates the grinding belt 5.

[0062] In this embodiment, Figure 1 , Figure 2, Figure 3 , Figure 4 , Figures 5 to 11 As shown, the sliding bar 8115 and the pressure strip 8112 have matching concave-convex patterns on their surfaces on opposite sides. When the sliding bar 8115 and the pressure strip 8112 are clamped together, the concave-convex patterns on their surfaces fit together to clamp the grinding belt 5, thereby avoiding tearing caused by the force applied by the penetrating nail 8117 along the grinding belt 5, thereby improving the stability of the fracture connection of the grinding belt 5.

[0063] A method for using a parts grinding device for automobile parts processing comprises the following steps:

[0064] S1, start the motor 3 to drive the grinding belt wheel 4 to rotate, so that the grinding belt 5 runs in the frame 1. At this time, the operator can put the automobile parts on the grinding table 6, and then push them to the grinding port 7 to use the grinding belt 5 for grinding.

[0065] S2. During the operation of the grinding belt 5, the compressed gas is input into the cylinder 82 along the hose 86 using the external connector 85, so that the air nozzle 84 sprays air toward the tautly running grinding belt 5, and generates a reverse thrust along the grinding belt 5, so that the cylinder 82 compresses the spring 83 to move forward. When the grinding belt 5 breaks, the reverse thrust of the air nozzle 84 is insufficient, and the spring 83 pushes the cylinder 82 to move backward, and drives the sliding clamp 88 to move synchronously to constrain along the broken end of the grinding belt 5.

[0066] S3, when the grinding belt 5 breaks and the sliding clamp 88 moves, the sliding clamp 88 pushes the pressure strip 8112 toward the slide bar 8115, so that the penetration nail 8117 pierces the grinding belt 5 and then inserts into the through hole 8118 for reverse locking, thereby controlling the slide bar 8115 and the pressure strip 8112 to be fixed along the broken portion of the grinding belt 5, and using the metal rope 8116 between the upper and lower slide bars 8115 to link the broken area of ​​the grinding belt 5. At this time, the grinding belt 5 can bring the upper and lower slide bars 8115 upward out of the slide groove and the lower slide groove 8114, so that the grinding belt 5 continues to run.

[0067] S4. When the lower slide bar 8115 slides upward from the lower groove 8114, the gear 811117 inside it is rotated by the rack 811111, and then drives another gear 811117 to rotate, so that it pushes the sliding pin 811114 along the tooth surface 811115 to move downward along the socket. At this time, the metal rope 8116 between the two slide bars 8115 is pulled shorter and the two broken ends of the grinding belt 5 are relatively brought closer.
