[0038] The driving member 2 is used to drive the spraying tube 4 to spray the bolts; when the driving member 2 is started, it can drive the spraying tube 4 to move. During the movement of the spraying tube 4, the spray head thereof can spray the bolts;

[0039] Also includes:

[0040] The pressure member 20 is mounted on the output end of the driving member 2, and the moving stroke of the driving member 2 has a first stroke and a second stroke. In the embodiment of the present invention, the driving mode of the driving member 2 is set to linear drive, removing the hydraulic cylinder and the linear electric push rod, etc. The pressure member 20 is mounted on the end of the driving member 2, and the displacement of the driving member 2 can drive the pressure member 20 to move accordingly. The pressure member 20 includes a column 201, a pressure rod 202, a first elastic member 203 and a contact member 303. The column 201 is mounted on the output end of the driving member 2, the pressure rod 202 is slidably inserted in the column 201, and the first elastic member 203 is mounted on the column 2 01, a section of the first elastic member 203 abuts against the end of the pressure rod 202, and the contact member 303 is installed on the outside of the column 201. When the driving member 2 is extended outward, the driving member 2 will drive the column 201 to move. The pressure rod 202 is slidably connected in the column 201, and the pressure rod 202 extends vertically downward. The first elastic member 203 is arranged in the column 201, and a cavity for the pressure rod 202 to make way is provided in the column 201. The first elastic member 203 is arranged in the cavity. As the driving member 2 extends, the column 201 is squeezed downward, so that the pressure rod 202 drives the clamping mechanism 10.

[0041] The linkage structure 30 is connected to the rotating platform 3 by transmission; the linkage structure 30 is connected to the rotating platform 3 by transmission, and the setting of the push rod linkage structure 30 can drive the rotating platform 3 to rotate at an angle, so that the bolt is fixed on the rotating platform 3 through the clamping mechanism 10, and when the rotating platform 3 rotates, the bolt fixed on it will be driven synchronously, so that the rotation of the rotating platform 3 drives the bolt to rotate, and when the spray head is spraying, the bolt rotates to spray the entire bolt surface, thereby ensuring the uniformity of the bolt surface spraying; the linkage structure 30 includes a transmission shaft 301, a receiving part 302, and a connecting part. The core shaft 308, the shaft 307, the bevel gear 309, and the transmission shaft 301 are rotatably connected to the housing 1, and the receiving member 302 is installed at the end of the transmission shaft 301. During the second stroke, the receiving member 302 receives the drive of the contact member 303, the core shaft 308 and the rotating platform 3 are fixedly connected, and the bevel gear 309 is installed at the end of the core shaft 308 and the shaft 307 respectively. The transmission shaft 301 and the shaft 307 are connected by a connecting portion. The linkage structure 30 is used to convert the kinetic energy of the pressure member 20 during the downward movement. After the receiving member 302 and the contact member 303 come into contact, the downward stroke of the pressure member 20 will drive the receiving member 302 to move, and the receiving member 30 2 rotates, and through the coupling effect of the transmission shaft 301, it can be synchronously transmitted to the connecting part, and the shaft 307 is driven to rotate by the connecting part. Through the meshing of the two bevel gears 309, the core shaft 308 can be synchronously driven to rotate. In this way, the core shaft 308 is fixedly installed below the rotating platform 3. When the core shaft 308 rotates, the rotating platform 3 can be synchronously driven to rotate accordingly. In this way, the bolts fixed on the rotating platform 3 can rotate synchronously, and the rotation of the rotating platform 3 is achieved by the downward pressure of the driving member 2. The downward pressure stroke of the driving member 2 is used to passively drive the rotating platform 3 to rotate, thereby achieving the purpose of reducing the configuration of the power unit;

[0042] In the first stroke, the pressure member 20 drives the clamping mechanism 10 to clamp the bolt. In the second stroke, while the clamping mechanism 10 clamps the bolt, the linkage structure 30 receives the drive of the pressure member 20 to drive the rotating platform 3 to rotate, and the spray pipe 4 sprays the bolt. The clamping mechanism 10 includes a clamping block 101, a pressing ring 103 and a slide 104. The slide 104 is provided on the rotating platform 3. The clamping block 101 is slidably connected in the slide 104. The pressing ring 103 is slidably sleeved on the rotating platform 3. The lower end of the clamping block 101 and the pressing ring 103 are fixedly connected. In the first stroke, the pressure rod 202 squeezes the pressing ring 103 downward to force the clamping block 101 to move downward synchronously and lock the bolt. A ball bearing 204 is provided at the bottom of the pressure rod 202. When the pressing ring 103 is slidably sleeved on the outside of the rotating platform 3, the pressing ring 103 surrounds the rotating platform 3. When the rotating platform 3 rotates, the pressing ring 103 will also move accordingly. When the pressing ring 103 moves downward, the height of the pressing ring 103 will move downward. When the pressing ring 103 moves downward, it can drive the clamping block 101 to move downward. The horizontal end set at the upper end of the clamping block 101 will move downward and contact the bolt to achieve the locking of the bolt. In the first stroke of the pressure piece 20, the pressure rod 202 will first contact the pressing ring 103. As the driving member 2 continues to move downward, the pressure rod 202 will apply pressure to the pressing ring 103. When the pressure is greater than the elastic force of the second elastic member 102, the pressing ring 103 will move downward, so that the bolt can be clamped. When the driving member 2 continues to move downward, the pressure piece 20 will move downward as it descends. The second stroke is performed. During the second stroke, the pressure rod 202 is kept in contact with the pressing ring 103, and the contact piece 303 is in contact with the receiver 302. The downward pressure stroke of the pressure piece 20 drives the receiver 302 to move, and the receiver 302 rotates. The coupling effect of the transmission shaft 301 can be synchronously transmitted to the connecting part, and the shaft 307 is driven to rotate through the connecting part. The core shaft 308 can be synchronously driven to rotate through the engagement of the two bevel gears 309. In this way, the core shaft 308 is fixedly installed below the rotating platform 3. When the core shaft 308 rotates, the rotating platform 3 can be synchronously driven to rotate accordingly. In this way, the bolt fixed on the rotating platform 3 can rotate synchronously, and since the spray pipe 4 is installed on the pressure piece 20, when the pressure piece 20 moves downward, the spray pipe 4 moves along the axial direction of the bolt and cooperates with the rotation of the bolt. It can realize linkage, that is, by moving the driving member 2 downward, the spray pipe 4 is driven, the bolt is clamped, and the rotating platform 3 is driven to rotate through the linkage structure 30. In this way, a set of driving structures is used to realize multiple functions, reduce the number of driving units, and save costs.

[0043] In another embodiment of the present invention, the pressure member 20 includes a column 201, a pressure rod 202, a first elastic member 203 and a contact member 303. The column 201 is installed at the output end of the driving member 2, the pressure rod 202 is slidably inserted in the column 201, the first elastic member 203 is installed on the column 201, a section of the first elastic member 203 abuts against the end of the pressure rod 202, and the contact member 303 is installed on the outside of the column 201. The first elastic member 203 is arranged inside the column 201. During the first stroke, the pressure rod 202 will always want to contract inside the column 201 and continuously compress the first elastic member 203 to help the pressure rod 202 to be smoothly pressed into the column 201 during the first stroke. In the first stroke of the pressure member 20, the pressure rod 202 will first contact the pressing ring 103. As the driving member 2 continues to move downward, the pressure rod 202 will apply pressure to the pressing ring 103. When the pressure is greater than the elastic force of the second elastic member 102, the pressing ring 103 will move downward, thereby achieving the clamping of the bolt, and when the driving member 2 continues to move downward, the pressure member 20 will perform the second stroke as it descends.

[0044] In another embodiment of the present invention, the spray pipe 4 is mounted on the column 201, and a section of the spray pipe 4 is connected to a feeding device. The feeding device can be a material pump that can transport the medium to the spray pipe 4. The spray pipe 4 also has a nozzle that sprays the bolt synchronously when the driving member 2 drives the spray pipe 4 downward. The travel switch is activated at the beginning of the second stroke, and controls the start of the feeding device to perform spraying.

[0045] In another embodiment of the present invention, the clamping mechanism 10 includes a clamping block 101, a pressing ring 103 and a slide 104. The slide 104 is provided on the rotating platform 3. The clamping block 101 is slidably connected in the slide 104. The pressing ring 103 is slidably sleeved on the rotating platform 3. The lower end of the clamping block 101 is fixedly connected to the pressing ring 103. In the first stroke, the pressure rod 202 squeezes the pressing ring 103 downward to force the clamping block 101 to move downward synchronously and lock the bolt. A ball 204 is provided at the bottom of the pressure rod 202. In the first stroke, the pressure rod 202 squeezes the pressing ring 103 downward to force the clamping block 101 to move downward synchronously and lock the bolt. A ball 204 is provided at the bottom of the pressure rod 202. The pressing ring 103 is slidably sleeved on the outside of the rotating platform 3, and the pressing ring 103 surrounds the rotating platform 3. When the rotating platform 3 rotates, the pressing ring 103 will also move accordingly. When the pressing ring 103 moves downward, the height of the pressing ring 103 will move downward. When the pressing ring 103 moves downward, it can drive the clamping block 101 to move downward. The horizontal end set at the upper end of the clamping block 101 will move downward and abut against the bolt to achieve locking of the bolt, and by setting a ball 204 at the bottom of the pressure rod 202, the ball 204 will abut against the pressing ring 103 when the pressure rod 202 moves downward. In this way, when the rotating platform 3 rotates, the pressure rod 202 helps the two to change from sliding abutment to rolling connection through the setting of the ball 204, thereby reducing friction and making the rotating platform 3 rotate more smoothly. The second elastic member 102 is provided in the rotating platform 3, and the upper end of the second elastic member 102 abuts against the clamping block 101. The second elastic member 102 is provided so as to abut against the bottom of the clamping block 101. When the pressure rod 202 is disengaged, the second elastic member 102 rebounds to drive the clamping block 101 upward, automatically releasing the bolt, and facilitating the removal of the bolt after the spraying is completed.

[0046] In another embodiment of the present invention, the linkage structure 30 includes a transmission shaft 301, a receiving member 302, and a connecting portion. The transmission shaft 301 is rotatably connected to the housing 1, and the receiving member 302 is mounted at the end of the transmission shaft 301. During the second stroke, the receiving member 302 receives the drive of the contact member 303. The core shaft 308 is fixedly connected to the rotating platform 3, and the bevel gear 309 is respectively mounted at the ends of the core shaft 308 and the shaft 307. The transmission shaft 301 and the shaft 307 are connected in a transmission manner via the connecting portion. The linkage structure 30 is used to convert the kinetic energy of the pressure piece 20 during the downward movement. After the receiving piece 302 and the contact piece 303 come into contact, the downward stroke of the pressure piece 20 will drive the receiving piece 302 to move, and the receiving piece 302 rotates. Through the coupling action of the transmission shaft 301, it can be synchronously transmitted to the connecting part. The connecting part includes a driving wheel 304, a passive wheel 306, and a connecting piece 305. The driving wheel 304 is installed at the end of the transmission shaft 301, and the passive wheel 306 is installed at the end of the shaft 307. The driving wheel 304 and the passive wheel 306 are connected by the connecting piece 305. The connecting part is used for transmission, and the driving wheel 304 is installed on a section of the transmission shaft 301. The driving wheel 304 and the receiving part 302 are installed coaxially, so that the driving wheel 304 and the driven wheel 306 are connected by the connecting part 305, and the two can also rotate synchronously. In this way, the downward pressure of the pressure piece 20 can be converted into the rotation of the rotating platform 3, and the shaft 307 is driven to rotate through the connecting part. Through the engagement of the two bevel gears 309, the core shaft 308 can be synchronously driven to rotate. In this way, the core shaft 308 is fixedly installed below the rotating platform 3. When the core shaft 308 rotates, the rotating platform 3 can be synchronously driven to rotate accordingly.

[0047] Preferably, the connecting portion includes a driving wheel 304, a driven wheel 306, and a connecting piece 305. The driving wheel 304 is mounted on the end of the transmission shaft 301, and the driven wheel 306 is mounted on the end of the shaft 307. The driving wheel 304 and the driven wheel 306 are connected to each other through the connecting piece 305. The connecting portion is used for transmission. The driving wheel 304 is mounted on a section of the transmission shaft 301. The driving wheel 304 and the receiving piece 302 are coaxially mounted. In this way, the driving wheel 304 and the driven wheel 306 are connected by the connecting piece 305. The two can also rotate synchronously. In this way, the downward pressure of the pressure piece 20 can be converted into the rotation of the rotating platform 3.

[0048] The transmission ratio between the driving wheel 304 and the driven wheel 306 is 1:3. The transmission ratio between the driving wheel 304 and the driven wheel 306 is 1:3, which can change the number of wheels between the driving wheel 304 and the driven wheel 306 to achieve output speed increase.

[0049] The contact member 303 is configured as a rack, and the receiving member 302 is configured as a gear. During the second stroke, the rack and gear mesh. The rack is mounted on the cylinder 201, and the gear is mounted on the transmission shaft 301. During the second stroke, the rack and gear mesh. As the cylinder 201 continues to move downward, the meshing action drives the gear to rotate, thus converting the linear motion of the cylinder 201 into the rotational motion of the gear.

[0050] The driving member 2 is configured as a hydraulic cylinder or a linear electric push rod. Through the hydraulic cylinder or the linear electric push rod, the pressure member 20 can be pushed to move back and forth in the vertical direction.

[0051] The working principle of the present invention is as follows: when in use, the bolt is installed on the rotating platform 3, and the screw head part of the bolt needs to be placed under the clamping block 101. The driving member 2 is turned on, the driving member 2 extends outward, and drives the pressure member 20 to move downward. The pressure rod 202 will first contact the pressing ring 103. As the driving member 2 continues to move downward, the pressure rod 202 will apply pressure to the pressing ring 103. When the pressure is greater than the elastic force of the second elastic member 102, the pressing ring 103 will move downward, so that the bolt can be clamped. During the continuous downward movement, the second stroke will begin. The starting point of the second stroke is that the rack and the gear are engaged. During the second stroke, first, the receiving member 302 (gear) receives the drive of the contact member 303 (rack). The rack is set on the column 201, and the gear is set On the transmission shaft 301, during the descent of the column 201, the gear will be driven to rotate through meshing, so that the linear motion of the column 201 can be converted into the rotational motion of the gear. The driving wheel 304 and the receiving member 302 (gear) are coaxially installed, so that the driving wheel 304 and the driven wheel 306 are connected by a connecting member 305, and the two can also rotate synchronously. In this way, the downward pressure of the pressure member 20 can be converted into the rotation of the rotating platform 3, so that the rotating platform 3 can be driven, and when the second stroke is in progress, the spray pipe 4 moves along the axial direction of the bolt, so that the material pump can transport the medium to the spray pipe 4, and the spray pipe 4 is also provided with a nozzle, which sprays the bolt synchronously when the driving member 2 drives the spray pipe 4 downward.
