Method used

The present invention mainly comprises mechanical overturning part and pneumatic control part, and overturning mechanism adopts the SMC standard cylinder of main cylinder CS1T125-300 (bore 125mm, stroke 300mm) as actuator axially overturns 180 °; Mechanical overturning part adopts rack and pinion The mechanism realizes the function of workpiece turning; employees only need to activate the control valve to realize the tooling axial turning 180° during operation. Because the air pressure setting of the main pipeline of the body factory is required to be 0.4-0.6Mpa, it shares the air source with the welding air pressure of the workshop (welding The air pressure pipeline is a controlled parameter in the workshop), so the air pressure stability of the air source of the control device is better; the automatic axial flipping mechanism of the rear floor clamp by 180° is changed from the worker’s flipping to the tooling’s automatic flipping, which reduces the labor intensity of the employees and solves the problem. The potential safety hazard of manual overturning improves the quality of the vehicle body.

The workpiece is lifted with a pneumatic balance, and the workpiece is put into the overturn frame 3 by the guide rod 16, the cylinder 10 is started, the jaws 9 are clamped to the workpiece, the jacking cylinder 4 i...

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] see figure 1 and figure 2 , an automatic axial overturning mechanism for clamps, including a support seat 1, a rotating shaft 2 is provided at both ends of the supporting seat 1, and a turning frame 3 is connected between the rotating shafts 2, and the rotating shaft 2 can drive the turning frame 3 to rotate through a jacking cylinder 4 .

[0026] The clamp automatic axial overturning mechanism of the present invention is used to replace the manual overturning of the rear floor assembly of the automobile, which has the advantages of high work efficiency, low labor intensity, and no hidden danger in operation, solves the problem of manual handling, and reduces the labor intensity of employees. Reduce sheet metal deformation and bump defects.

[0027] As a preference, the rotating shaft 2 at one end of the support seat 1 is set in the bearing 5, the rotating shaft 2 at the other end is connected to the gear 6, the gear 6 is connected to the rack 7, the rack 7 is arranged on the jacking cylinder 4, and the rack 7 The lower part is connected with the hinge ear of the cylinder, and the hinge ear of the cylinder is connected with the jacking cylinder; the upper part of the rack 7 is connected with the gear 6, and the lower part of the jacking cylinder 4 is connected with the cylinder seat 8, and the cylinder seat 8 is arranged on the support seat 1; 3 is provided with jaws 9, and the jaws 9 are symmetrically arranged on the four corners of the overturn frame 3, wherein two jaws 9 are arranged on one side of the overturn frame 3, and two jaws 9 are arranged below, and one is arranged on the left and right sides. The clamping jaws 9 and the setting of the clamping jaws 9 on the other side are also the same. Each clamping jaw 9 is correspondingly connected to a cylinder 10, and the cylinder 10 can control the closing of the clamping jaws 9 connected thereto.

[0028] Because the rear floor assembly of the car is relatively large and the overall rigidity is not very strong, it is necessary to use multiple jaws to fix it when clamping to prevent the plate from falling during the flipping process.

[0029] In order to enable the workpiece to be accurately positioned when it is put into the reversing frame 3 , a guide rod 16 is respectively provided on the two beams of the reversing frame 3 .

[0030] see image 3 , in order to facilitate the transfer of the turned workpiece to the next process and continue to complete the assembly of the car, there are pulleys 11 under the support base 1, two pulleys 11 on the left and right, and two on the two slide rails 12, and the support base 1 passes through Cross bar 13 is connected, and cross bar 13 is connected bottom cylinder 14. The cylinder at the bottom is connected with the overturning mechanism, and the pulley rolls on the slide rail when advancing to achieve the purpose of operation.

[0031] In order to prevent the pulley from shifting during operation, the bottom cylinder 14 guide rod is deformed, so the slide rail 12 is installed to control the running accuracy. The two ends of the slide rail 12 are provided with buffer seats 15, which are convenient for the mechanism to stop when it is in place.

[0032] A buffer pad 17 is arranged on the support base 1 , and the buffer pad 17 is arranged diagonally between the support base 1 and the turning frame 3 . The main function is to reduce the impact of the impulse force generated by the turning mechanism on the fixture itself.

[0033] Brief description of the mechanism operation of the embodiment of the present invention:

[0034] Lift the workpiece with a pneumatic balance crane, put the workpiece on the flip frame 3 through the guide rod 16, start the cylinder 10, make the jaws 9 clamp the workpiece, start the jacking cylinder 4, and the jacking cylinder 4 pushes the rack 7 to drive the gear 6 rotates, the gear 6 drives the rotating shaft 2 connected to it to rotate, thereby driving the overturning frame 3, the jaws 9 and the workpiece to overturn at the same time; The claw 9 is opened by the cylinder 10, and resets after hoisting the workpiece. The turnover speed of the workpiece can be adjusted by the flow limiting valve to achieve fast and slow speed. The flow limiting valve comes with the cylinder, which is used to control the size of the compressed air passing through the cylinder. Too slow affects the production beat.

[0035] The invention mainly includes a mechanical overturning part and a pneumatic control part. The overturning mechanism adopts a master cylinder CS1T125-300 (bore 125mm, stroke 300mm) SMC standard cylinder as an actuator to overturn 180° axially; the mechanical overturning part uses a rack and pinion mechanism to realize the workpiece Flip function; employees only need to activate the control valve to realize the tooling axial flip 180° during operation, because the air pressure setting requirement of the main pipeline of the body factory is 0.4~0.6Mpa, and the welding air pressure of the workshop shares the air source (welding air pressure pipeline is the controlled parameter of the workshop), so the air source pressure stability of the control device is better; the automatic axial flipping mechanism of the rear floor fixture by 180° is changed from the worker’s flipping to the tooling’s automatic flipping, which reduces the labor intensity of the employees and solves the problem of manual flipping Potential safety hazards have been improved and the quality of the body has been improved.

[0036] The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. within range.
