Description

Technical Field

[0001] The utility model relates to the field of positioning devices, in particular to a positioning device for cutting automobile interior decorations. Background Art

[0002] With the continuous improvement of living standards, the quality of people's lives is getting higher and higher. Cars have become a means of transportation for families, and many people pay more attention to the interior of the car when buying a car. The interior of the car is divided into many categories, such as car steering wheel covers, car seat cushions, car floor mats, car perfumes, car pendants, internal ornaments, storage boxes, etc. are all car interior products, and the car roof also belongs to the car interior. The ceiling needs to be cut by a cutting device during production, and a positioning device needs to be used to position the raw materials during cutting to avoid deviation problems during cutting.

[0003] According to a car interior ceiling cutting device with publication number CN220218712U, it includes a workbench, a groove is opened at the upper end of the workbench, the groove can collect waste residues generated when the car interior ceiling is cut, and it is convenient for staff to clean it. Positioning rods are symmetrically fixed on the front and rear walls of the groove, and a fixing component is provided on the upper end of the positioning rod. The fixing component can fix the car interior ceiling to facilitate subsequent cutting. By twisting the twist cover, the twist cover drives the adjusting rod to rotate, and the adjusting rod drives the rectangular pressing block to move up and down, so as to adjust the distance between the rectangular pressing block and the placement plate, which is convenient for staff to put on the car interior ceiling. By twisting the twist cover in the opposite direction, the rectangular pressing block and the placement plate can be clamped and fixed together.

[0004] However, the above-mentioned patent is rather troublesome when fixing the interior ceiling, and the twist cover needs to be rotated several times to realize the up and down movement of the rectangular pressing block, and both sides need to be rotated, which is rather troublesome and reduces the work efficiency. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a positioning device for cutting automobile interior decoration to solve the technical problems mentioned in the above background technology.

[0014] The utility model is further configured such that a hanging ear is fixed to the end of the second limiting rod, and a through hole is opened in the middle of the hanging ear.

[0015] By adopting the above technical solution, the second limit rod can be easily pulled manually through the provided hanging ear.

[0016] The utility model is further configured such that the cross section of the receiving block is configured to be L-shaped.

[0017] By adopting the above technical solution, the receiving block arranged in an L-shape can be better supported on the bottom of the limiting block, thereby preventing the limiting block from rotating.

[0018] The utility model is further configured that a rotating disk is fixed on the end of the rotating rod.

[0019] By adopting the above technical solution, the arranged turntable can facilitate personnel to rotate the turn bar.

[0020] The utility model is further configured that a movable groove is provided at the bottom of the receiving plate.

[0021] By adopting the above technical solution, the movement direction of the limiting rod can be conveniently limited by the provided moving groove.

[0045] Embodiment 2

[0046] A positioning device for cutting automobile interior decoration, such as Figure 5 - Fig. 9 As shown, the technical scheme and parts of this embodiment are basically the same as those of the first embodiment, and the technically identical parts will not be described in detail here. The difference is that (if there are not two solutions to the same problem, it can be written as follows: a slider 91 is movably installed on one side of the bottom of the receiving plate 4, and a connecting rod 9 is movably installed on the bottom of the slider 91, and the end of the connecting rod 9 is movably connected to the first limiting rod 52, and limiting protrusions 93 are fixed on both sides of the top of the slider 91, and a sliding groove 43 matching the slider 91 is provided at the bottom of the receiving plate 4, and a limiting groove 44 matching the limiting protrusion 93 is provided on the inner wall of the sliding groove 43. By cooperating with the limiting protrusion 93, the problem of separation of the slider 91 and the receiving plate 4 can be avoided. There are two groups of insertion rods 11, and a cross bar 10 is fixed at the end of the insertion rod 11. A socket 92 is provided on one side of the slider 91. When the interior ceiling needs to be fixed, the pressure rod 5 is pressed downward. When the pressure rod 5 moves downward, it drives the fixing rod 51 to move downward. When the fixing rod 51 moves downward, it drives the first limit rod 52 to move downward. When the first limit rod 52 moves downward, it drives the end of the connecting rod 9 to move, and the end of the connecting rod 9 moves downward. The other end of the connecting rod 9 drives the slider 91 to slide inside the slide groove 43. When the two groups of sliders 43 approach each other and slide to one side of the inner wall of the slide groove 43, the cross bar 10 is pushed inward. The cross bar 10 drives the insertion rod 11 to move inward, so that the insertion rod 11 is inserted into the socket 92, thereby completing the fixation of the two groups of sliders 91. The operation is simple.

[0047] The working principle of the utility model is as follows: when in use, the motor drives the screw rod 21 to rotate. According to the screw rod principle, when the screw rod 21 rotates, it drives the receiving plate 4 to move, and the interior ceiling is placed above the receiving plate 4. Then the turntable 71 is rotated, and the turntable 17 drives the rotating rod 7 to rotate. When the rotating rod 7 rotates, it drives the protrusion 72 to rotate. When the protrusion 72 rotates, it squeezes the first limit rod 52, and the first limit rod 52 is squeezed and moves downward. When the first limit rod 52 moves downward, it drives the fixing rod 51 downward. When the fixing rod 51 moves downward, it drives the pressing rod 5 downward at the same time, thereby achieving the purpose of fixing the interior ceiling placed above the receiving plate 4, and then pushes the second limit rod 8, and the second limit rod 8 moves inward, driving the receiving block 82 to move, and the receiving block 82 is engaged with the bottom of the limit block 74, thereby completing the limiting of the limit block 74 and preventing the rotating rod 7 from reversing.

[0048] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
