Description

Technical Field

[0001] The invention relates to the field of production and processing of automobile accessories, in particular to a universal tool for spray painting a bumper. Background Art

[0002] To improve efficiency and reduce labor, many companies are now using painting robots to spray car bumpers. However, to maintain efficiency, the robot's spray gun maintains a fixed trajectory. This necessitates positioning each workpiece in a specific position to match the spray gun's trajectory. Currently, specialized tooling is used to position and support the bumper, ensuring it maintains a consistent trajectory.

[0003] In actual operation, it is often necessary to spray paint bumpers of various specifications, and different bumpers require different tooling for support and fixation. Therefore, operators need to change different tooling, which increases workload and company operating costs.

[0004] Therefore, a method or device that can solve the above problems is needed. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned deficiencies in the prior art and proposes a universal tooling for painting which has a simple structure, ingenious design, reasonable layout and can be adapted to a variety of bumpers of different specifications to achieve the purpose of reducing labor and saving costs.

[0017] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. Figure 1 、 Figure 2 、 Figure 3 The figure shows a universal tool for painting a bumper, comprising a bottom frame 1, rollers 2 disposed at the four corners of the bottom frame 1, two sets of primary longitudinal support sleeves 3 symmetrically disposed in the middle of the bottom frame 1, primary longitudinal support rods 4 movably sleeved within the primary longitudinal support sleeves 3, and top screws 5 matching the primary longitudinal support rods 4 threadedly connected to the side walls of the primary longitudinal support sleeves 3; The primary longitudinal support rod 4 is connected to the bottom of the intermediate frame 6, and the intermediate frame 6 includes two horizontal support sleeves 7 that are parallel to each other and horizontally distributed. A horizontal adjustment rod 8 is movably sleeved in the horizontal support sleeve 7, and a top screw 5 that matches the horizontal adjustment rod 8 is threadedly connected to the side wall of the horizontal support sleeve 7; The end of the horizontal adjustment rod 8 is provided with a first arc-shaped bracket 9 and a secondary longitudinal support sleeve 10, a secondary longitudinal support rod 11 is movably sleeved in the secondary longitudinal support sleeve 10, a top screw 5 matching the secondary longitudinal support rod 11 is threadedly connected on the side wall of the secondary longitudinal support sleeve 10, and a second arc-shaped bracket 12 is provided on the top of the secondary longitudinal support rod 11; The middle portion of the intermediate frame 6 is further connected to a positioning platform 13 via a plurality of support rods, and a plurality of positioning mechanisms are provided on the positioning platform 13 .

[0018] The positioning mechanism includes a T-shaped connector 14, which is provided with an X-axis long slot 15 and a Y-axis long slot 16. The T-shaped connector 14 is connected to the positioning platform 13 via a bolt connected to the X-axis long slot 15, and a first positioning pin 17 is connected in the Y-axis long slot 15.

[0019] The ends of the first positioning pins 17 are distributed vertically.

[0020] The ends of the first positioning pins 17 are distributed horizontally.

[0021] The positioning platform 13 is provided with a connecting base 18 , which is distributed along the central axis of the positioning platform 13 in the longitudinal direction. Two universal adjustment positioning devices are provided on the connecting base 18 , and the universal adjustment positioning devices are provided with a second positioning pin 19 .

[0022] A third positioning pin 20 is further provided on the positioning platform 13 , and the end of the third positioning pin 20 is horizontally distributed.

[0023] A plurality of equally spaced annular connecting platforms 21 are provided at both ends of the positioning platform 13 , and positioning posts 22 are sleeved on the annular connecting platforms 21 .

[0024] The universal bumper painting tooling of the embodiment of the present invention operates as follows: When a bumper of a certain specification needs to be automatically painted, the number and specific positions of the positioning and limiting mechanisms installed on the positioning platform 13 are selected based on the specific conditions of the bumper (such as the distribution position and direction of the various positioning holes, the overall length, etc.), and the first arc-shaped bracket 9 or the second arc-shaped bracket 12 is selected to support the bumper. When the bumper is supported by the device, it assumes a specific posture in space that matches the motion trajectory of the robot arm in space, thereby ensuring the painting effect. When it is necessary to replace a bumper of another specification for painting operation, the number and specific positions of the positioning and limiting mechanisms on the positioning platform 13 can be changed, and it can be decided whether to use the first arc-shaped bracket 9 or the second arc-shaped bracket 12 to support the current bumper, so as to ensure that the bumper can still be placed in a specific posture in space that coincides with the movement trajectory of the manipulator, thereby ensuring the painting effect; When the overall height of the workpiece needs to be adjusted, the relative position between the first-level longitudinal support sleeve 3 and the first-level longitudinal support rod 4 can be adjusted, and after adjustment, the top screw 5 can be tightened to fix the two. When the distance between the two arc-shaped brackets needs to be adjusted, the relative position between the horizontal support sleeve 7 and the horizontal adjustment rod 7 can be adjusted. After adjustment, tighten the top screw 5 to fix the two. When the second arc-shaped bracket 12 is needed, it is only necessary to insert the secondary longitudinal support rod 11 into the secondary longitudinal support sleeve 10, adjust the relative position between the two, and then fix them with the top screw; In the positioning mechanism provided on the positioning platform 13, since the T-shaped connector 14 is provided with an X-axis slot 15 and a Y-axis slot 16, the first positioning pin 17 can be adjusted over a wide range relative to the positioning platform 13 according to actual conditions. That is, the first positioning pin 17 has adjustment freedom in both the X-axis and Y-axis directions relative to the positioning platform 13, thereby allowing the end of the first positioning pin 17 to be adjusted to a suitable position. In actual operation, the specific structure of the bumper to be manufactured determines whether the first positioning pin 17 is to be distributed vertically or horizontally. The connecting base 18 on the positioning platform 13 can be made of a profile, and the universal adjustment positioning device is connected to the groove on the profile. The universal adjustment positioning device can drive the second positioning pin 19 to achieve multi-directional and multi-degree-of-freedom adjustment in space. At the same time, the universal adjustment positioning device itself can also be adjusted on the connecting base 18 (the base of the universal adjustment positioning device is slidably connected to the groove of the profile and can be fixed to the profile by bolts), thereby changing the specific position of the second positioning pin 19 to ensure that it can support and position bumpers of different specifications; According to actual needs, the third positioning pin 20 can be fixedly connected to a suitable position on the positioning platform 13, or the positioning column 22 can be sleeved on the annular connecting platform 21 to support and position the bumper.
