[0002] With the rapid development of the automotive industry, car navigation systems, as important devices to enhance the driving experience and travel convenience, are experiencing increasing market demand. In the manufacturing process of car navigation systems, shell assembly is one of the key links, and the precision and quality of shell assembly directly affect the overall performance, appearance, and service life of the navigation system.
[0003] When assembling the casing of a car navigation system, a universal clamp is usually used for clamping and positioning. However, such clamps are difficult to precisely adapt to the special shape and size of the car navigation system casing. Moreover, the casing of the navigation system is generally made of plastic. When clamping, it is easy to deform due to excessive clamping, which will cause errors in subsequent processes such as drilling and splicing, and there are certain shortcomings.
[0004] Therefore, a positioning and calibration fixture for assembling car navigation system housings is provided to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a car navigation device housing assembly positioning calibration fixture.

A fixing plate is fixedly connected to one end of the tooling plate; The movable clamping plate is slidably connected to the tooling plate, and the movable clamping plate is threadedly connected to the lead screw. By rotating the lead screw, the movable clamping plate can move on the tooling plate. A limiting component, mounted on the tooling plate, is used to restrict the movement of the movable clamping plate and prevent damage to the housing caused by excessive clamping.
[0007] Preferably, the limiting assembly includes a moving rod, a first spring, a conical block, a limiting rod, a second spring, and a limiting groove.

The spring is sleeved on the moving rod, and its two ends are fixedly connected to the movable clamping plate and the conical block, respectively. Multiple sets of limiting grooves are equally spaced on the tooling plate. The limiting rod is slidably connected to the movable clamping plate. One end of the second spring is fixedly connected to the limiting rod, and the other end abuts against the surface of the tooling plate. By moving the moving rod, the conical block can move, thereby squeezing the limiting rod and causing it to move downward, thus inserting into the limiting groove and restricting the movement of the movable clamping plate.
[0008] Preferably, a mounting plate is fixedly connected to the movable clamping plate, the mounting plate is provided with a hole that matches the conical block, a limit ring is fixedly connected to the mounting plate, and the limit rod is slidably connected inside the limit ring.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Example: Reference Figure 1-4 A car navigation system housing assembly, positioning, and calibration fixture includes a fixture plate 1, and further includes: a groove 102 disposed on the fixture plate 1; a lead screw 103 rotatably connected within the groove 102; a fixed clamping plate 2 fixedly connected to one end of the fixture plate 1; a movable clamping plate 3 slidably connected to the fixture plate 1, the movable clamping plate 3 being threadedly connected to the lead screw 103, allowing the movable clamping plate 3 to move on the fixture plate 1 through the rotation of the lead screw 103; and a limiting component disposed on the fixture plate. 1. A limiting assembly is used to restrict the movement of the movable clamping plate 3 to prevent damage to the outer casing due to excessive clamping. The limiting assembly includes a moving rod 501, a first spring 502, a conical block 503, a limiting rod 601, a second spring 602, and a limiting groove 104. The moving rod 501 passes through the movable clamping plate 3, and the conical block 503 is fixedly connected to the moving rod 501. The first spring 502 is sleeved on the moving rod 501, and its two ends are fixedly connected to the movable clamping plate 3 and the conical block 503, respectively. Multiple limiting assemblies are used. The grooves 104 are evenly spaced on the tooling plate 1. The limiting rod 601 is slidably connected to the movable clamping plate 3. One end of the spring element 602 is fixedly connected to the limiting rod 601, and the other end abuts against the surface of the tooling plate 1. By moving the moving rod 501, the conical block 503 can move, and then the conical block 503 presses the limiting rod 601 to move downward, and then inserts into the limiting groove 104, restricting the movement of the movable clamping plate 3. The movable clamping plate 30 is fixedly connected to the movable clamping plate 3. 1. The mounting plate 301 is provided with a hole 302 that matches the conical block 503. A limit ring is fixedly connected to the mounting plate 301. The limit rod 601 is slidably connected in the limit ring. The tooling plate 1 is provided with multiple sets of slots 101 for installing the punch plate. The movable clamping plate 3 is slidably connected with a pressing plate 5. The end of the moving rod 501 away from the conical block 503 is fixedly connected to the pressing plate 5. The movable clamping plate 3 and the fixed clamping plate 2 are both fixedly connected with a base plate 4 for placing the navigator housing.
[0017] The tooling in this device mainly includes a tooling plate 1, a fixed clamping plate 2, a movable clamping plate 3, a lead screw 103, and a limiting assembly. The tooling plate 1 is a rectangular plate structure with multiple sets of slots 101 on its surface for mounting perforated plates. A groove 102 is provided in the middle. The lead screw 103 is rotatably connected to the groove 102 through a bearing. The fixed clamping plate 2 is fixed to one end of the tooling plate 1. The movable clamping plate 3 slides with the guide rail on the tooling plate 1 through a slider at the bottom and is threadedly connected to the lead screw 103. By rotating the lead screw 103, the movable clamping plate 3 can be driven to move linearly along the tooling plate 1, thereby clamping and releasing the navigator housing.
[0018] The limiting assembly includes a moving rod 501, a first spring 502, a conical block 503, a limiting rod 601, a second spring 602, and a limiting groove 104. The moving rod 501 horizontally passes through the movable clamping plate 3 and slides with it. One end is fixedly connected to the extrusion plate 5, and the other end is fixedly connected to the conical block 503. The first spring 502 is sleeved on the moving rod 501, and both ends are fixedly connected to the movable clamping plate 3 and the conical block 503 respectively, so that the conical block 503 is kept in the initial position under normal conditions.
[0019] A mounting plate 301 is fixed on the movable clamping plate 3. The mounting plate 301 has a hole 302 that matches the conical block 503. A limit ring is fixed at the bottom. A limit rod 601 is vertically slidably connected inside the limit ring. A spring element 602 is sleeved on the upper part of the limit rod 601. One end is fixed to the limit rod 601, and the other end abuts against the bottom surface of the mounting plate 301. Multiple sets of limit grooves 104 are evenly spaced along the moving direction of the movable clamping plate 3 on the surface of the tooling plate 1. The lower end of the limit rod 601 can be inserted into the limit groove 104 to achieve the positioning of the movable clamping plate 3.
[0020] When the extrusion plate 5 is squeezed by the navigator housing, it pushes the moving rod 501 to move to the right. The conical block 503 moves to the right and squeezes the limiting rod 601, causing it to overcome the elastic force of the second spring 602 and move downward into the limiting groove 104, restricting the movement of the movable clamping plate 3 and preventing excessive clamping that could deform the housing. When it is necessary to release the housing, the screw 103 is rotated in the opposite direction, the movable clamping plate 3 moves backward, the first spring 502 pushes the conical block 503 to reset, and the limiting rod 601 disengages from the limiting groove 104 under the action of the second spring 602, and the movable clamping plate 3 returns to its free movement state.
[0021] In practical use, the navigator housing to be assembled is placed on the base plate 4 of the fixed clamping plate 2 and the movable clamping plate 3, ensuring that the bottom of the housing is in full contact with the base plate 4. Then, the lead screw 103 is rotated, at which point the movable clamping plate 3 moves towards the fixed clamping plate 2, gradually clamping the housing. When the housing is clamped to a certain extent, the pressing plate 5 is pressed by the housing, pushing the moving rod 501 to the right. The conical block 503 presses the limiting rod 601 to insert it into the limiting groove 104, and the movable clamping plate 3 stops moving, achieving positioning and preventing over-clamping. Then, according to the housing processing requirements, a suitable punching plate is selected and installed into the slot 101 of the tooling plate 1. The housing is punched through the positioning holes on the punching plate. Subsequently, the remaining car navigation components are installed at the punched holes. Finally, the lead screw 103 is rotated in the opposite direction, the movable clamping plate 3 is moved back, and the spring 502 and the spring 602 respectively reset the conical block 503 and the limiting rod 601, and the processed housing is taken out.
[0022] This utility model, through the setting of fixed clamping plate 2 and movable clamping plate 3, can quickly lock and clamp the navigator shell placed on the tooling plate 1. At the same time, through the setting of limiting components, it can reduce the deformation of the car navigator shell caused by excessive clamping, fix and calibrate it, reduce the subsequent drilling misalignment caused by deformation, and facilitate the subsequent assembly and splicing of the navigator shell.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
