Description

A car bumper painting bracket Technical Field

[0001] This utility model belongs to the field of automotive bumper painting technology, and in particular relates to an automotive bumper painting bracket. Background Technology

[0002] As an important protective device for the front and rear of a vehicle, car bumpers are generally made of plastic, metal, or composite materials. Their main function is to absorb energy during a collision, protecting the vehicle's structure and pedestrian safety. After the paint finish on the car bumper has been applied and is awaiting initial curing, it is usually placed on a painting rack and sent to a paint booth for drying and curing.

[0003] Currently, traditional car bumper painting brackets are generally equipped with fixed clamps to hold the painted bumpers in place. However, these clamps are usually designed for specific bumper sizes, meaning that in practical applications, the entire clamp must be replaced when different bumper sizes need to be processed. This process is not only time-consuming but also reduces ease of use.

[0004] In summary, existing automotive bumper painting brackets suffer from limited applicability and poor ease of operation. Summary of the Invention

[0005] This utility model provides a car bumper painting bracket, which can solve the problems of narrow applicability and poor ease of operation and use of existing car bumper painting brackets.

[0006] To achieve the above objectives, an automobile bumper painting bracket is provided according to an embodiment of the first aspect of the present invention, comprising a frame and mounting posts fixedly installed at the four corners of the frame;

[0007] Also includes:

[0008] The clamping and fixing assembly includes a pair of bases disposed on both sides of the frame and respectively connected to two mounting columns on the same side, a double-ended lead screw rotatably disposed in each base, sliding seats threaded on both sides of the double-ended lead screw, and clamping blocks disposed on both sides of the base surface and respectively connected to each sliding seat.

[0009] A further improvement is that the base is provided with a first mounting cavity and a second mounting cavity, and the double-ended lead screw is rotatably disposed in the first mounting cavity.

[0010] A further improvement is that the double-ended lead screw is provided with two opposite threaded teeth, and the two sliding seats are respectively threaded onto the two opposite threaded teeth of the double-ended lead screw.

[0011] A further improvement is that a DC servo motor is fixedly installed inside the second mounting cavity, and the main shaft of the DC servo motor is connected to a double-ended lead screw.

[0012] A further improvement is that the surface of the base is provided with a sliding groove that communicates with the mounting cavity, and the bottom surface of each clamping block passes through the sliding groove and is fixedly connected to each sliding seat respectively.

[0013] A further improvement is that each of the gripping blocks is made of soft rubber.

[0014] A further improvement is that mounting grooves are provided on both sides of the base, and the bottom surface of each mounting groove extends out of the base.

[0015] A further improvement is that the base is provided with a fixing screw at the position corresponding to each mounting slot.

[0016] A further improvement is that the frame has several positioning grooves on the surface between two mounting columns on the same side.

[0017] A further improvement is that the bottom surface of the base is fixedly installed with positioning posts that are matched with each positioning slot.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) This utility model uses two DC servo motors that start synchronously. Each DC servo motor drives a double-ended lead screw to rotate. Since the double-ended lead screw has two sections of threaded teeth with opposite directions, and the two sliding seats are threadedly connected to these two sections of threaded teeth respectively, under the rotation of the double-ended lead screw, the two sliding seats will move in opposite directions and gradually move closer together, thereby driving the clamping block to move synchronously until the edge of the car bumper is firmly clamped. This design allows the device to be adapted to bumpers of different specifications, eliminating the need for frequent clamp changes and greatly improving the convenience of operation.

[0020] (2) This utility model inserts the two sides of the clamping and fixing component into the corresponding positions of the mounting column, so that the positioning column on the bottom surface of the base and the positioning groove are precisely matched. Then, the base and the mounting column are firmly connected by fixing screws. In this way, the clamping and fixing component can be easily installed and disassembled, so that the frame can be flexibly converted into other uses, thereby enhancing the practicality and multifunctionality of the entire bracket.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] As shown in Figures 1 to 3, a car bumper painting bracket includes a frame 1 and mounting posts 12 fixedly installed at the four corners of the frame 1.

[0030] The clamping and fixing assembly 2 includes a pair of bases 21 disposed on both sides of the frame 1 and respectively connected to two mounting columns 12 on the same side, a double-ended lead screw 22 rotatably disposed in each base 21, a sliding seat 23 threaded on both sides of the double-ended lead screw 22, and a clamping block 24 disposed on both sides of the surface of the base 21 and respectively connected to each sliding seat 23.

[0031] Specifically, the base 21 is provided with a first mounting cavity 201 and a second mounting cavity 202. A double-ended lead screw 22 is rotatably mounted in the first mounting cavity 201. The double-ended lead screw 22 is provided with two opposite threaded teeth. Two sliding seats 23 are respectively threaded onto the two opposite threaded teeth of the double-ended lead screw 22. A DC servo motor 25 is fixedly mounted in the second mounting cavity 202. The spindle of the DC servo motor 25 is connected to the double-ended lead screw 22. The surface of the base 21 is provided with a groove 203 that communicates with the first mounting cavity 201. The bottom surface of each gripping block 24 passes through the groove 203 and is fixedly connected to each sliding seat 23. The surface of the second mounting cavity 202 is connected to the outside. The two DC servo motors 25 are started synchronously. Each DC servo motor 25 drives the double-ended lead screw 22 to rotate. Since the double-ended lead screw 22 has two sections of threaded teeth with opposite directions of rotation, and the two sliding seats 23 are threadedly connected to these two sections of threaded teeth respectively, under the rotation of the double-ended lead screw 22, the two sliding seats 23 will move in opposite directions and gradually approach each other, thereby driving the clamping block 24 to move synchronously until the edge of the car bumper is firmly clamped. This design allows the device to adapt to bumpers of different specifications, eliminating the need for frequent clamp changes and greatly improving operational convenience.

[0032] As a preferred embodiment, each clamping block 24 is made of soft rubber, and the rubber clamping block 24 is used to protect the edge of the car bumper;

[0033] As a preferred embodiment, mounting slots 204 are provided on both sides of the base 21, and the bottom surface of each mounting slot 204 extends out of the base 21. A fixing screw 205 is provided on the base 21 at the position corresponding to each mounting slot 204. By inserting both sides of the clamping and fixing component 2 into the corresponding positions of the mounting post 12, the base 21 and the mounting post 12 are then securely connected using the fixing screws 205. In this way, the clamping and fixing component 2 can be easily installed and removed, allowing the frame 1 to be flexibly converted to other uses, thereby enhancing the practicality and multifunctionality of the entire support.

[0034] As a preferred embodiment, the frame 1 has several positioning grooves 11 on the surface between two mounting columns 12 on the same side. The bottom surface of the base 21 is fixedly installed with positioning columns 3 that are installed in each positioning groove 11. The positioning columns 3 on the bottom surface of the base 21 are precisely matched with the positioning grooves 11, which can further improve the connection and fixing effect.

[0035] As shown in Figures 1 to 3, in this embodiment, it should also be noted that the actual dimensions and shapes of the components in the application documents are selected and installed according to the actual needs of the site before implementation. Furthermore, it should be noted that this application only addresses the shortcomings of existing automotive bumper painting brackets, such as narrow applicability and poor ease of operation, and does not involve other aspects. The working principle of this automotive bumper painting bracket is described below:

[0036] In using this novel solution, firstly, workers hoist the pre-coated and cured car bumper onto the frame 1. Then, according to the specific specifications of the bumper, two DC servo motors 25 are simultaneously activated. Each DC servo motor 25 drives a double-ended lead screw 22 to rotate. Since the double-ended lead screw 22 has two sections of threaded teeth with opposite directions, and two sliding seats 23 are threadedly connected to these two sections of threaded teeth, under the rotation of the double-ended lead screw 22, the two sliding seats 23 will move in opposite directions and gradually approach each other, thereby driving the clamping block 24 to move synchronously until the edge of the car bumper is firmly clamped. This design allows the device to adapt to bumpers of different specifications, eliminating the need for frequent clamp changes and greatly improving operational convenience.

[0037] Furthermore, during the implementation of this solution, by inserting the two sides of the clamping and fixing component 2 into the corresponding positions of the mounting posts 12, the positioning posts 3 on the bottom surface of the base 21 are precisely engaged with the positioning grooves 11. Subsequently, the base 21 and the mounting posts 12 are securely connected using the fixing screws 205. In this way, the clamping and fixing component 2 can be easily installed and disassembled, allowing the frame 1 to be flexibly converted to other uses, thereby enhancing the practicality and multifunctionality of the entire bracket.

[0038] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
