Description

Technical Field

[0001] This utility model relates to the field of vehicle instrument manufacturing technology, specifically a positioning tooling for vehicle instrument manufacturing. Background Technology

[0002] Positioning fixtures for automotive instrument manufacturing are specialized jigs used to precisely fix instrument components or housings during the machining and assembly process. By stably clamping and positioning the automotive instruments, they improve assembly efficiency, consistency, and product quality. They are key auxiliary equipment in automated production lines to ensure the accuracy of instrument assembly.

[0003] A positioning structure for producing a combination instrument cover, disclosed in Chinese Patent Publication No. CN218082307U, involves sliding two sets of fixing plates on top of a limiting sliding plate to place the instrument cover between the two sets of fixing plates. The two sets of fixing plates clamp and fix the instrument cover, facilitating subsequent processing. However, the overall functionality of the positioning fixture is low. During the clamping and positioning of the vehicle instrument, it is impossible to record the processing status of the vehicle instrument in real time, thus affecting the subsequent processing effect of the vehicle instrument and the practicality of the positioning fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture for the production of vehicle instrument panels, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for manufacturing vehicle instruments, comprising a base, with limiting grooves provided inside both sides of the top of the base, hydraulic rods installed on both sides of the top of the base, a clamping seat that slides within the limiting grooves installed on one side of the hydraulic rods, a fitting mechanism provided inside the clamping seat, a moving mechanism provided on both sides inside the base, a camera provided at the top of the moving mechanism, and an instrument body provided at the middle position of the top of the base.

[0006] Preferably, the bonding mechanism includes a power supply port installed on one side of the top of the clamping seat, a conductive plate installed at the bottom of the power supply port, and wrapping bags evenly arranged at equal intervals inside the clamping seat, with a first spring fixedly connected inside the wrapping bags.

[0007] Preferably, the interior of the packaging bag is filled with electrorheological fluid, and the packaging bag is made of silicone rubber and filled with carbon nanotubes.

[0008] Preferably, a limiting slider is slidably connected at equal intervals on one side of the inside of the clamping seat, and one side of the limiting slider is in contact with the package bag. A rubber head is fixedly connected to one side of the limiting slider.

[0009] Preferably, the moving mechanism includes a rack fixedly connected to the bottom end of one side of the clamping seat, a gear rotatably connected to the bottom end of one side of the limiting groove, a winding shaft fixedly connected to the top end of the gear, and a pull rope fixedly connected to one side of the winding shaft.

[0010] Preferably, a movable block is fixedly connected to one side of the pull rope, a second spring is fixedly connected to one side of the movable block, and a connecting block whose top end is connected to the camera is fixedly connected to the top end of the movable block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This positioning fixture for vehicle instrument production features a rack on one side of the clamping seat. When the hydraulic rod pushes the clamping seat to clamp the vehicle instrument, the rack on one side of the clamping seat can drive the gear to rotate. At this time, the winding shaft at the top of the gear pulls the pull rope to wind up, which can cause the pull rope to pull the camera to move through the moving block. At the same time, the moving block can compress the second spring on one side. The camera can then take pictures and record the vehicle instrument clamped by the clamping seat. When the clamping seat releases the vehicle instrument, the moving block can drive the camera to reset due to the reaction force of the second spring being compressed. Thus, the camera can move and take pictures of the vehicle instrument during and after the clamping work of the positioning fixture, thereby recording the processing status of the vehicle instrument, facilitating subsequent verification work, and improving the overall functionality of the vehicle instrument positioning fixture.

[0013] 2. This positioning fixture for manufacturing vehicle instruments features multiple sets of rubber heads on one side of the clamping seat. When the rubber heads contact the upper end of the vehicle instrument, a limiting slider compresses the first spring inside the packaging bag. Due to the reaction force of the compressed first spring, the limiting slider pushes the rubber heads to adhere to the surface of the upper end of the vehicle instrument. At this time, energizing the conductive plate through the power supply port causes the electrochemical fluid inside the packaging bag to solidify, thus fixing the position of the rubber heads. This allows the positioning fixture to stably perform positioning work for vehicle instruments of different specifications, improving the overall functionality of the positioning fixture and the stability of the vehicle instruments in subsequent use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides two technical solutions:

[0022] Example 1: A positioning fixture for manufacturing vehicle-mounted instruments includes a base 1. Limiting grooves 101 are provided inside both sides of the top of the base 1. Hydraulic rods 2 are installed on both sides of the top of the base 1. A clamping seat 201 that slides within the limiting grooves 101 is installed on one side of the hydraulic rods 2. A fitting mechanism 3 is provided inside the clamping seat 201. Moving mechanisms 6 are provided on both sides inside the base 1. A camera 7 is installed at the top of the moving mechanism 6. An instrument body 8 is positioned in the middle of the top of the base 1. The limiting grooves 101 can provide auxiliary limiting for the clamping seat 201. The clamping seat 201 can be pushed by the hydraulic rods 2 to perform clamping and positioning work on the vehicle-mounted instrument. The camera 7 can capture images of the exterior of the vehicle-mounted instrument at the top of the base 1.

[0023] The moving mechanism 6 includes a rack 202 fixedly connected to the bottom end of one side of the clamping seat 201; a gear 601 rotatably connected to the bottom end of one side of the limiting groove 101; a winding shaft 602 fixedly connected to the top end of the gear 601; a pull rope 603 fixedly connected to one side of the winding shaft 602; a moving block 604 fixedly connected to one side of the pull rope 603; a second spring 605 fixedly connected to one side of the moving block 604; and a connecting block 606 fixedly connected to the top end of the moving block 604, which connects to the camera 7. When the holder 201 moves, the rack 202 at the bottom of one side of the holder 201 can drive the gear 601 to rotate. At this time, the gear 601 drives the take-up shaft 602 to rotate, which can drive the pull rope 603 to wind up. The pull rope 603 then pulls the moving block 604 and the camera 7 to move. At the same time, the moving block 604 can squeeze the second spring 605 on one side. Due to the reaction force of the second spring 605 being squeezed, when the moving block 604 is not under force, it can be pushed to reset.

[0024] Example 2 differs from Example 1 mainly in that:

[0025] A positioning fixture for manufacturing vehicle instruments includes a bonding mechanism 3 comprising a power supply port 301 mounted on one side of the top of a clamping seat 201, a conductive plate 302 mounted on the bottom of the power supply port 301, and packaging bags 4 evenly spaced inside the clamping seat 201. A first spring 401 is fixedly connected inside the packaging bags 4, and the packaging bags 4 are filled with electrorheological fluid. The packaging bags 4 are made of silicone rubber and filled with carbon nanotubes. Silicone rubber has excellent elasticity, and the carbon nanotubes can improve conductivity, thereby energizing the electrorheological fluid inside the packaging bags 4. When the power supply port 301 energizes the electrorheological fluid inside the packaging bags 4 through the conductive plate 302, the electrorheological fluid solidifies, which can fix the position of the limiting slider 5 and the rubber head 501.

[0026] One side of the clamping seat 201 is equidistantly and evenly connected to a limiting slider 5, which is in contact with the package bag 4 on one side. A rubber head 501 is fixedly connected to one side of the limiting slider 5. When the rubber head 501 contacts the vehicle instrument and is subjected to force, it can squeeze the first spring 401 inside the package bag 4 through 502. Due to the reaction force of the first spring 401 being squeezed, the limiting slider 5 can push the rubber head 501 to adhere to the outside of the vehicle instrument. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] In this embodiment, the vehicle instrument to be positioned is placed at the center of the top of the base 1. The hydraulic rod 2 at the top of the base 1 is then activated to push the clamping seat 201 to clamp the vehicle instrument. Simultaneously, the rubber head 501 on one side of the clamping seat 201 contacts the upper end of the vehicle instrument. The limiting slider 5 can compress the first spring 401 inside the packaging bag 4. Due to the reaction force of the compressed first spring 401, the limiting slider 5 pushes the rubber head 501 to adhere to the upper end of the vehicle instrument. At this time, power is supplied to the clamping seat 201 via the power supply port 301. When the circuit board 302 is energized, the conductive plate 302 can energize and solidify the electrorheological fluid inside the packaging bag 4, and fix the position of the rubber head 501, so that the rubber head 501 is stably attached to the outside of the vehicle instrument. At the same time, during the movement of the clamping seat 201, the gear 601 can be driven to rotate by the rack 202 on one side. The gear 601 drives the top winding shaft 602 to rotate, which can pull the pull rope 603 to wind up. The pull rope 603 drives the camera 7 to move through the moving block 604, so that the camera 7 can capture the positioning and processing of the vehicle instrument.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
