Description

Technical Field

[0001] This utility model relates to the field of automotive infotainment screen back cover clamping technology, specifically to a multi-functional composite clamping fixture for automotive infotainment screen back cover, used to clamp the automotive infotainment screen back cover and the process boss for integral cutting. Background Technology

[0002] The rear cover of the vehicle infotainment screen serves as a key component supporting the rear of the car's display screen. One side connects to the infotainment screen, and the other side connects to the car's center console. The cast rear cover is a blank and requires further finishing. This finishing process involves first using a fixture to position and clamp the rear cover for positioning. However, the rear cover lacks effective clamping positions, and these positions must not interfere with the machining process. Therefore, process bosses are added around the rear cover for positioning and clamping. After machining, the rear cover is transferred to another fixture for separate removal of the process bosses. This separate process for removing the process bosses not only reduces machining efficiency but also requires a separate fixture, increasing processing costs. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-functional composite fixture for the rear cover of a vehicle infotainment screen. This fixture can not only position and clamp the rear cover of the vehicle infotainment screen through the process boss, facilitating further processing of the rear cover of the vehicle infotainment screen, but also perform secondary clamping of the rear cover of the vehicle infotainment screen to achieve integrated removal of the process boss.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0005] A multi-functional composite fixture for the rear cover of a vehicle infotainment screen includes a middle plate. Multiple pressure plates and clamping plates are arranged on the middle plate, distributed circumferentially along the rear cover of the vehicle infotainment screen. Each pressure plate has a boss support rod at its bottom, pressing the process bosses on the rear cover of the vehicle infotainment screen onto the boss support rod. Each clamping plate has a rear cover support rod at its bottom, pressing the rear cover of the vehicle infotainment screen onto the rear cover support rod. Each clamping plate has a tool clearance groove at its bottom, used to allow space for tools to process the outer contour of the rear cover of the vehicle infotainment screen.

[0006] In use, the clamping plate is in the open state. First, the pressure plate presses the process bosses on the outer contour of the vehicle screen back cover onto the boss support rod, positioning and clamping the vehicle screen back cover for machining the inner cavity of the vehicle screen back cover. After the inner cavity of the vehicle screen back cover is machined, the clamping plate presses the vehicle screen back cover onto the back cover support rod, positioning and clamping the vehicle screen back cover. The pressure plate is released, and the tool clearance groove at the bottom of the clamping plate makes way for the tool to machine the outer contour of the vehicle screen back cover, so as to machine the outer contour of the vehicle screen back cover and remove the process bosses on the vehicle screen back cover.

[0007] The rear cover support rod is located at the head end of the clamping plate. The clamping plate is provided with a clamping plate bracket shaft and a clamping plate power shaft. The clamping plate bracket shaft is connected to the clamping plate bracket, and the clamping plate power shaft is connected to the clamping plate cylinder. The clamping plate cylinder drives the clamping plate to rotate on the clamping plate bracket with the clamping plate bracket shaft as the axis. The clamping plate presses the rear cover of the vehicle screen onto the rear cover support rod, thereby clamping the rear cover of the vehicle screen.

[0008] The clamping plate bracket shaft is located between the rear cover support rod and the clamping plate power shaft. The clamping plate bracket includes a clamping plate bracket seat and a clamping plate hinge plate. The clamping plate bracket shaft is connected to one end of the clamping plate hinge plate, and the other end of the clamping plate hinge plate is provided with a clamping plate hinge plate shaft. The clamping plate hinge plate shaft is set on the clamping plate bracket seat. The clamping plate rotates on the clamping plate hinge plate with the clamping plate bracket shaft as the axis, and the clamping plate hinge plate rotates on the clamping plate bracket seat with the clamping plate hinge plate shaft as the axis. In use, when the clamping cylinder drives the clamping plate to clamp the rear cover of the vehicle infotainment screen, the clamping plate rotates on the clamping plate hinge plate with the clamping plate bracket shaft as the axis, and the clamping plate hinge plate rotates on the clamping plate bracket seat with the clamping plate hinge plate shaft as the axis. The clamping plate hinge plate swings from the clamping cylinder toward the rear cover of the vehicle infotainment screen to achieve clamping of the rear cover of the vehicle infotainment screen. When the clamping cylinder drives the clamping plate to release the rear cover of the vehicle infotainment screen, the clamping plate hinge plate swings from the rear cover of the vehicle infotainment screen toward the clamping cylinder side so that the head end of the clamping plate disengages from the top of the rear cover of the vehicle infotainment screen, making it easier to put on and take off the rear cover of the vehicle infotainment screen.

[0009] The boss support rod is set at the head end of the pressure plate. The pressure plate is provided with a pressure plate bracket shaft and a pressure plate power shaft. The pressure plate bracket shaft is connected to the pressure plate bracket, and the pressure plate power shaft is connected to the pressure plate cylinder. The pressure plate cylinder drives the pressure plate to rotate on the pressure plate bracket with the pressure plate bracket shaft as the axis. The pressure plate presses the process boss onto the boss support rod, thereby clamping the process boss on the outer contour of the vehicle screen back cover.

[0010] The pressure plate bracket shaft is located between the boss support rod and the pressure plate power shaft. The pressure plate bracket includes a pressure plate bracket seat and a pressure plate hinge plate. The pressure plate bracket shaft is connected to one end of the pressure plate hinge plate, and the other end of the pressure plate hinge plate is provided with a pressure plate hinge plate shaft. The pressure plate hinge plate shaft is mounted on the pressure plate bracket seat. The pressure plate rotates on the pressure plate hinge plate with the pressure plate bracket shaft as its axis, and the pressure plate hinge plate rotates on the pressure plate bracket seat with the pressure plate hinge plate shaft as its axis. In use, when the pressure plate cylinder drives the pressure plate to clamp the process boss, the pressure plate rotates on the pressure plate hinge plate with the pressure plate bracket shaft as the axis, and the pressure plate hinge plate rotates on the pressure plate bracket seat with the pressure plate hinge plate shaft as the axis. The pressure plate hinge plate swings from the pressure plate cylinder toward the process boss side to achieve clamping of the process boss. When the pressure plate cylinder drives the pressure plate to release the process boss, the pressure plate hinge plate swings from the process boss toward the pressure plate cylinder side so that the head end of the pressure plate disengages from above the process boss, making it easier to remove and put away the rear cover of the vehicle screen.

[0011] The middle plate is provided with multiple vehicle screen rear cover support blocks, which are used to support the bottom of the vehicle screen rear cover and improve the clamping stability of the vehicle screen rear cover.

[0012] The middle plate is provided with multiple positioning posts for the rear cover of the vehicle infotainment screen. These positioning posts are positioned and supported at the bottom of the rear cover of the vehicle infotainment screen, facilitating the positioning and placement of the rear cover.

[0013] This utility model uses a pressure plate and a clamping plate to perform two positioning clamps on the rear cover of the vehicle infotainment screen, and uses a tool clearance groove to allow the tool to process the outer contour of the rear cover of the vehicle infotainment screen. This not only enables the processing of the surface of the rear cover of the vehicle infotainment screen, but also enables the removal of process bosses and the processing of the outer contour of the rear cover of the vehicle infotainment screen.

[0014] This invention combines the removal of process bosses on the same fixture, which not only improves the processing efficiency of the vehicle screen back cover, but also avoids the need for a separate fixture, thus reducing processing costs. Attached Figure Description

The eight pressure plates 4 and four clamping plates 5 are distributed around the circumference of the rear cover 7. The pressure plates 4 are located at the process boss 71.

[0021] Each pressure plate 4 has a boss support rod 41 at its bottom, located at the head end of the pressure plate 4. The pressure plate 4 is equipped with a pressure plate bracket shaft 42 and a pressure plate power shaft 46. The pressure plate bracket shaft 42 is located between the boss support rod 41 and the pressure plate power shaft 46. The pressure plate bracket shaft 42 is connected to one end of the pressure plate hinge piece 43. The other end of the pressure plate hinge piece 43 is equipped with a pressure plate hinge piece shaft 44, which is mounted on a pressure plate bracket seat 45. The pressure plate bracket seat 45 is connected to the pressure plate cylinder. The pressure plate power shaft 46 is connected to the piston rod 47 of the pressure plate cylinder 48. The piston rod 47 of the pressure plate cylinder 48 drives the tail end of the pressure plate 4. The pressure plate 4 and the piston rod 47 rotate around the pressure plate power shaft 46. The pressure plate 4 rotates on the pressure plate hinge plate 43 around the pressure plate bracket shaft 42. The pressure plate hinge plate 43 rotates on the pressure plate bracket seat 45 around the pressure plate hinge plate shaft 44, so as to realize that the head end of the pressure plate 4 approaches / moves away from the boss support rod 41, thereby realizing the clamping and release of the process boss 71.

[0022] It should be noted that when the pressure plate cylinder drives the pressure plate to clamp the process boss, the pressure plate rotates on the pressure plate hinge plate with the pressure plate bracket shaft as the axis, and the pressure plate hinge plate rotates on the pressure plate bracket seat with the pressure plate hinge plate shaft as the axis. The pressure plate hinge plate swings from the pressure plate cylinder towards the process boss side to achieve clamping of the process boss. When the pressure plate cylinder drives the pressure plate to release the process boss, the pressure plate hinge plate swings from the process boss towards the pressure plate cylinder side so that the head end of the pressure plate disengages from above the process boss, facilitating the removal and placement of the vehicle infotainment screen back cover.

[0023] Each clamping plate 5 has a rear cover support rod 51 at its bottom, located at the head end of the clamping plate 5. The clamping plate 5 is equipped with a clamping plate bracket shaft 52 and a clamping plate power shaft 56. The clamping plate bracket shaft 52 is located between the rear cover support rod 51 and the clamping plate power shaft 56. The clamping plate bracket shaft 52 is connected to one end of the clamping plate hinge piece 53. The other end of the clamping plate hinge piece 53 is equipped with a clamping plate hinge piece shaft 54, which is mounted on a clamping plate bracket seat 55. The clamping plate bracket seat 55 is connected to the clamping plate hydraulic cylinder. The clamping plate power shaft 56 is connected to the piston rod 57 of the clamping plate cylinder 58. The piston rod 57 of the clamping plate cylinder 58 drives the tail end of the clamping plate 5. The clamping plate 5 and the piston rod 57 rotate around the clamping plate power shaft 56. The clamping plate 5 rotates on the clamping plate hinge plate 53 around the clamping plate bracket shaft 52. The clamping plate hinge plate 53 rotates on the clamping plate bracket seat 55 around the clamping plate hinge plate shaft 54, so as to realize that the head end of the clamping plate 5 approaches / moves away from the rear cover support rod 51, thereby realizing the clamping and release of the vehicle screen rear cover 7.

[0024] It should be noted that when the clamping cylinder drives the clamping plate to press the rear cover 7 of the vehicle infotainment screen, the clamping plate rotates on the clamping plate hinge plate with the clamping plate bracket shaft as the axis, and the clamping plate hinge plate rotates on the clamping plate bracket seat with the clamping plate hinge plate shaft as the axis. The clamping plate hinge plate swings from the clamping cylinder toward the rear cover 7 of the vehicle infotainment screen to achieve clamping of the rear cover 7 of the vehicle infotainment screen. When the clamping cylinder drives the clamping plate to release the rear cover 7 of the vehicle infotainment screen, the clamping plate hinge plate swings from the rear cover 7 of the vehicle infotainment screen toward the clamping cylinder side so that the head end of the clamping plate disengages from the top of the rear cover 7 of the vehicle infotainment screen, making it easier to put on and take off the rear cover of the vehicle infotainment screen.

[0025] The bottom of the clamping plate 5 is provided with a tool clearance groove 59, which is used to make way for the tool to process the outer contour of the vehicle screen rear cover 7.

[0026] In use, clamping plate 5 is in the open state. First, the pressure plate 4 presses the process bosses of the outer contour of the vehicle screen back cover onto the boss support rod 41 to position and clamp the vehicle screen back cover for processing the surface of the vehicle screen back cover. After the surface of the vehicle screen back cover is processed, clamping plate 5 presses the vehicle screen back cover 7 onto the back cover support rod 51 to position and clamp the vehicle screen back cover. Then, the pressure plate 4 is released, and the tool clearance groove 59 at the bottom of clamping plate 5 makes way for the tool to process the outer contour of the vehicle screen back cover, so as to process the outer contour of the vehicle screen back cover and remove the process bosses on the vehicle screen back cover.

[0027] In this embodiment, the rear cover of the vehicle infotainment screen is positioned and clamped twice by a pressure plate and a clamping plate, and the tool clearance groove makes way for the tool to process the outer contour of the rear cover of the vehicle infotainment screen. This not only enables the processing of the surface of the rear cover of the vehicle infotainment screen, but also enables the removal of process bosses and the processing of the outer contour of the rear cover of the vehicle infotainment screen.

[0028] In this embodiment, the removal of the process boss is carried out on the same fixture, which not only improves the processing efficiency of the vehicle screen back cover, but also avoids the need for a separate fixture, thus reducing processing costs.

[0029] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
