Description

Technical Field

[0001] The invention relates to the technical field of fork spraying and grinding to remove burrs, in particular to a fork abrasive spraying device with a burr removing function. Background Art

[0002] With the rapid development of manufacturing industry and the widespread application of logistics equipment, the performance and quality requirements for logistics equipment such as forks are getting higher and higher. As an important part of logistics equipment, the surface quality of forks directly affects the service life and safety of the equipment. The abrasive jet processing technology can effectively remove burrs on the surface of forks, improve surface quality, and reduce safety hazards and maintenance costs caused by burrs.

[0003] Abrasive jet processing technology is a process that mixes abrasive powder (such as quartz sand, corundum, glass beads) with a certain pressure of gas (such as air, nitrogen or carbon dioxide), and then sprays it at high speed from a nozzle hole of a specific diameter. The impact and destructive effect of the abrasive is used to remove material from the workpiece. This technology is mainly used for deburring, polishing, engraving and other processing types.

[0004] The abrasive jet deburring methods commonly used at present mostly only perform a single deburring of the fork, and are unable to detect the roughness of the fork after deburring, as well as perform subsequent precise abrasive jet deburring. In addition, since the abrasive jet deburring technology is to spray a mixture of abrasive powder and gas with a certain pressure at high speed, after the burrs are removed, the powder will fall into the operating room and need to be cleaned up in time.

A mounting groove is provided on the side of the gantry top frame facing the base plate, and the mounting groove is connected to the abrasive deburring mechanism.

[0010] In the main mechanism, this mechanism serves as the basis of the entire fork abrasive jetting device. The base plate and the gantry are fastened together to fix and support the gantry. The cross-section of the lower half of the gantry side frame is a triangular structure, which can better stabilize the entire gantry. The mounting groove at one end of the gantry top frame facing the base plate is used to install the abrasive deburring mechanism. The base plate is used to provide a foundation for the installation of the roughness detection mechanism and the abrasive cleaning mechanism.

[0011] Furthermore, the abrasive deburring mechanism includes a moving device, which is connected to the mounting groove.

After the abrasive deburring mechanism is started, the abrasive collecting box transmits the abrasive to the conveying pipeline, the air compressor discharges the compressed air to the conveying pipeline, the compressed air drives the abrasive through the grinding tube, and finally ejects from the high-speed nozzle. The compressed air carries the abrasive and sprays onto the fork body to remove the burrs on the fork body. At the same time, the grinding tube is tightly connected to the mobile mounting block. After the mobile device is started, the mobile mounting block will move left and right along the mobile track. Therefore, the grinding tube and The high-speed nozzle tightly connected to the abrasive blasting tube will also move with it, while the fork body is held stationary by the rotating gripper, with the plane below the fork body facing upwards. At the same time, the fork body is located directly below the mobile mounting block, and the fixing direction of the abrasive blasting tube is consistent with the moving direction of the mobile mounting block. After the mobile mounting block starts to move, the high-speed nozzle continues to spray abrasive to deburr the fork body, so that the deburring of one side of the fork body can be completed. After completing the deburring of one side, the rotating gripper starts, clamping the fork body for rotation. After rotating 180°, the inclined surface of the bottom of the fork faces upwards, and the drive motor starts again to drive the mobile track to rotate. The mobile mounting block moves with the abrasive blasting tube to deburr the inclined surface of the fork body.

[0015] Furthermore, the roughness detection mechanism includes a first measuring block, a second measuring block, a variable pitch support rod, a measuring block rotating shaft rod, a measuring block moving platform, a strong electromagnet, a hydraulic cylinder and an ultrasonic velocimeter, one end of the hydraulic cylinder is fastened to the gantry side frame, the end of the hydraulic cylinder away from the gantry side frame is fastened to one side of the measuring block moving platform, the bottom of the measuring block moving platform is fastened to the bottom plate, the measuring block moving platform is an inverted "L" shape, a fixing rod is fixedly connected to the measuring block moving platform, a stopper is arranged at one end of the measuring block moving platform close to the hydraulic cylinder, and a A strong electromagnet; a second measuring block is slidably connected to the measuring block moving platform, two variable pitch support rods are provided, variable pitch support rods are fixedly connected on both sides of the second measuring block, a mounting hole is provided in the middle of the first measuring block, the measuring block rotating shaft is transmission-connected to the mounting hole of the first measuring block, both ends of the measuring block rotating shaft are tightly connected to the two variable pitch support rods, a moving groove is provided on the upper half of the variable pitch support rod, the diameter of the measuring block rotating shaft is tangent to both sides of the moving groove, the ultrasonic velocimeter is fixedly installed on the gantry side frame, and the height of the ultrasonic velocimeter is consistent with the center height of the first measuring block.

[0016] In the roughness detection mechanism, the first measuring block and the second measuring block are both hollow metal blocks, a mounting hole is provided in the middle of the first measuring block, the measuring block rotating shaft is transmission-connected to the first measuring block, the measuring block rotating shaft is fastened to the variable pitch support rod, the first measuring block and the second measuring block are connected through the measuring block rotating shaft and the variable pitch support rod, the upper and lower ends of the variable pitch support rod are semicircular, the center of the lower end of the variable pitch support rod coincides with the center of the side surface of the second measuring block, a moving groove of the same shape as the variable pitch support rod is provided on the variable pitch support rod, the inner wall of the moving groove is tangent to the measuring block rotating shaft, such a design allows the first measuring block to move up and down along the moving groove of the variable pitch support rod, and when the measuring block rotates When the shaft and the bottom of the moving groove are tangent, the distance between the first measuring block and the second measuring block is the shortest, which is the minimum height of the end of the fork body. The powerful electromagnet is set at the end of the measuring block moving platform. The roughness of the measuring block moving platform is small and will not affect the movement of the measuring block. After the fork body completes the initial deburring operation, the hydraulic cylinder pushes the measuring block moving platform to move. When the end of the measuring block moving platform and the fork body are in contact, they stop and the powerful electromagnet is powered on to generate magnetic force, attracting the second measuring block to move in the direction of the powerful electromagnet. The second measuring block drives the first measuring block to move together. Due to the gradual increase in the height of the fork body on both sides in the direction of the powerful electromagnet, In addition, the distance between the first measuring block and the second measuring block can be automatically adjusted by the variable distance support rod and the measuring block rotating shaft rod. After reaching the position of the strong electromagnet, the power is stopped, and the ultrasonic speed meter is turned on. Since the upper surface of the fork body is an inclined surface, the first measuring block will slide along the inclined surface, driving the second measuring block together. The roughness of the measuring block moving platform is relatively small and will not affect the second measuring block, but only provide a supporting force for the second measuring block. During the sliding process, the measuring block moving platform supports the second measuring block so that the upper surface of the second measuring block is always connected to the fork body in a sliding manner. In the process of the first measuring block and the second measuring block sliding down, due to the fork body The distance between the upper and lower sides of the fork body gradually decreases, and the distance between the first measuring block and the second measuring block will gradually decrease until the fork body slides out. At this time, the measuring block rotating shaft connected to the first measuring block just fits the bottom of the moving groove on the variable pitch support rod. During the movement, the ultrasonic velocimeter continuously detects the first measuring block. When a low speed or no movement is detected, it proves that the friction coefficient at this location is large, and there are burrs that have not been cleaned up. The electrical signal is transmitted to the abrasive deburring mechanism, the motor drive device is driven to move, and the high-speed nozzle sprays abrasive to perform deburring operation. After completion, the hydraulic cylinder drives the measuring block moving platform back to the initial position.

[0017] Furthermore, the abrasive cleaning mechanism includes a side filter, a bottom filter and a support plate. There are two side filters, which are symmetrically arranged on both sides of the fork body. One end of the side filter is fastened to the bottom plate, and the side filter is inclined. One end of the support plate is fastened to the bottom plate, and the end of the support plate away from the bottom plate is fastened to the side filter. The bottom filter is placed on the collecting trough of the bottom plate.

[0018] In the abrasive cleaning mechanism, the device is used to clean the abrasive splashed after deburring. The abrasive is filtered through the side filter. Smaller burrs will pass through the side filter, while the abrasive cannot pass through. At the same time, since the side filter is placed at an angle, the abrasive and burrs will move downward while being filtered until they reach the bottom filter. The bottom filter performs secondary filtering on the abrasive and the filtered burrs, so that the burrs fall into the collection groove of the bottom plate, while the abrasive remains on the bottom filter. After the device has worked for a period of time, the used abrasive on the bottom filter can be collected and re-polished so that it can be used as an abrasive to remove the burrs again.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: after starting, the rotating gripper clamps the fork body in the positive direction so that the inclined surface of the fork body faces downward, the driving motor drives the moving track to rotate, and the moving mounting block is driven to move left and right through the threaded engagement, and the blasting tube and the high-speed nozzle will also move with it to deburr the fork body. After completion, the rotating gripper clamps the fork body for 180° rotation, the inclined surface of the bottom of the fork faces upward, and the driving motor drives another deburring operation. After completion, the hydraulic cylinder pushes the measuring block moving platform to move, and the end of the measuring block moving platform fits the fork body. The powerful electromagnet is powered on to generate magnetic force, attracting the second measuring block to move in the direction of the powerful electromagnet, and the second measuring block drives the first measuring block to move together. After reaching the position of the powerful electromagnet, the power is stopped, the ultrasonic speed meter is turned on, the upper surface of the fork body is an inclined surface, and the first measuring block will move along The inclined plane slides, driving the second measuring block together. The measuring block moving platform will not affect the second measuring block. In the process of the first measuring block and the second measuring block sliding down, the distance between the first measuring block and the second measuring block will gradually decrease. Finally, the measuring block rotating shaft connected to the first measuring block just fits the bottom of the moving groove on the variable pitch support rod. During the movement, the ultrasonic velocimeter continuously detects the first measuring block. When it detects a low speed or no movement, it proves that the friction coefficient at this location is large, and there are burrs that have not been cleaned up. The electrical signal is transmitted to the abrasive deburring mechanism for precise deburring. After that, the hydraulic cylinder drives the measuring block moving platform back to the initial position. The abrasive cleaning mechanism cleans the abrasive splashed after burr removal. The abrasive is retained on the filter screen through two filter screens while the burrs are filtered out. The abrasive can be collected and re-polished so that it can be used as a burr removal tool again. BRIEF DESCRIPTION OF THE DRAWINGS

Since the upper surface of the fork body 1 is an inclined surface, the first measuring block 41 will slide along the inclined surface, driving the second measuring block 42 together. The roughness of the measuring block moving platform 45 is relatively small, and will not affect the second measuring block 42, but only provide a supporting force for the second measuring block 42. In the sliding process, the measuring block moving platform 45 supports the second measuring block 42 so that the upper surface of the second measuring block 42 is always connected to the fork body 1 in a sliding manner. When the first measuring block 41 and the second measuring block 42 move downward, the measuring block moving platform 45 supports the second measuring block 42 so that the upper surface of the second measuring block 42 is always connected to the fork body 1 in a sliding manner. During the sliding process, as the distance between the upper and lower sides of the fork body 1 gradually decreases, the distance between the first measuring block 41 and the second measuring block 42 will gradually decrease until it slides out of the fork body 1. At this time, the measuring block rotating shaft 44 connected to the first measuring block 41 just fits the bottom of the moving groove on the variable pitch support rod 43. During the movement, the ultrasonic velocimeter continuously detects the first measuring block 41. When a low speed or no movement is detected, it proves that the friction coefficient at this location is large, and there are burrs that have not been cleaned up. The electrical signal is transmitted to the abrasive deburring mechanism 3, the driving motor 311 drives the device to move, and the high-speed nozzle 35 sprays abrasives to perform deburring operations. After completion, the hydraulic cylinder 47 drives the measuring block moving platform 45 back to the initial position.

[0041] like Figure 1 , 7As shown, the abrasive cleaning mechanism 5 includes a side filter 51, a bottom filter 52 and a support plate 53. Two side filters 51 are provided, and the two side filters 51 are symmetrically arranged on both sides of the fork body 1. One end of the side filter 51 is fastened to the bottom plate 22, and the side filter 51 is inclined. One end of the support plate 53 is fastened to the bottom plate 22, and the end of the support plate 53 away from the bottom plate 22 is fastened to the side filter 51, and the bottom filter 52 is placed on the collecting trough of the bottom plate 22.

[0042] In the abrasive cleaning mechanism 5, the device is used to clean the abrasive splashed after deburring. The abrasive is filtered through the side filter 51. Smaller burrs will pass through the side filter 51, while the abrasive cannot pass through. At the same time, since the side filter 51 is placed at an angle, the abrasive and burrs will move downward while being filtered until they reach the bottom filter 52. The bottom filter 52 performs secondary filtering on the abrasive and the filtered burrs, so that the burrs fall into the collection groove of the bottom plate 22, while the abrasive remains on the bottom filter 52. After the device has worked for a period of time, the used abrasive on the bottom filter 52 can be collected and re-polished so that it can be used as an abrasive to remove the burrs again.

[0043] Working principle of the present invention: after starting, the present invention rotates and grips the fork body 1 in the positive direction, so that the inclined surface of the fork body 1 faces downward, and the driving motor 311 drives the moving track 312 to rotate, and drives the moving mounting block 313 to move left and right through the threaded engagement, and the blasting tube 34 and the high-speed nozzle 35 also move with it to deburr the fork body 1. After completion, the rotating gripper 36 grips the fork body 1 and rotates 180°, so that the inclined surface of the bottom of the fork faces upward, and the driving motor 311 drives to perform another deburring operation. After completion, the hydraulic cylinder 47 pushes the measuring block moving platform 45 to move, and the end of the measuring block moving platform 45 fits with the fork body 1. The powerful electromagnet 46 is powered on to generate magnetic force, attracting the second measuring block 42 to move toward the powerful electromagnet 46, and the second measuring block 42 drives the first measuring block 41 to move together. After reaching the position of the powerful electromagnet 46, the power is stopped, and the ultrasonic speed meter is turned on. The upper surface of the fork body 1 is an inclined surface, and the first measuring block 41 will slide along the inclined surface, driving the second measuring block 42 together, and the measuring block moving platform 45 will not affect the second measuring block 42. In the process of the first measuring block 41 and the second measuring block 42 sliding down, the distance between the first measuring block 41 and the second measuring block 42 will gradually decrease. Finally, the measuring block rotating shaft 44 connected to the first measuring block 41 just fits the bottom of the moving groove on the variable pitch support rod 43. During the movement, the ultrasonic velocimeter continuously detects the first measuring block 41. When it detects that the speed is low or motionless, it proves that the friction coefficient at this location is large, and there are burrs that have not been cleaned up. The electrical signal is transmitted to the abrasive deburring mechanism 3 for precise deburring. After that, the hydraulic cylinder 47 drives the measuring block moving platform 45 back to the initial position. The abrasive cleaning mechanism 5 cleans the abrasive splashed after the burr is removed. The abrasive is retained on the filter screen through the two filter screens while the burrs are filtered out. The abrasive can be collected and re-polished so that it can be used as a burr removal tool again.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
