Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a processing fixture for an automotive radar bracket. Background Technology

[0002] A car radar bracket is a component used to fix a car radar in a specific location on a vehicle, typically for driver assistance and safety systems. Its main function is to secure the radar to the front of the vehicle, such as the front grille, bumper, or roof. It ensures the radar's accurate installation position and angle, provides necessary mechanical calibration, and offers some protection to the radar components and pedestrians in the event of a minor collision. Furthermore, the radar bracket has a dustproof sealing function, adapts to harsh road conditions, and ensures the radar's normal operation. However, car radar brackets are thin-walled components with high precision requirements for their mounting holes. Direct isomorphic die casting cannot meet these precision requirements. Therefore, machining is used to process the mounting holes, necessitating a specific machining fixture to ensure that the product does not deform during clamping. Utility Model Content

[0007] Furthermore, the main clamping assembly includes a support base and a first lever cylinder.

[0008] Furthermore, the auxiliary clamping assembly includes a first push rod, a first hydraulic support cylinder, and a second lever cylinder. The first push rod is mounted on the first hydraulic support cylinder, and the first push rod and the second lever cylinder are used to clamp the vehicle radar bracket.

[0009] Furthermore, it also includes a support rod, which is disposed on the base plate.

[0010] Furthermore, when the car radar bracket is in a clamped state, there is a gap between the support rod and the car radar bracket.

[0011] Furthermore, a second push rod and a second hydraulic support cylinder are also provided on the base plate.

[0012] Furthermore, the base plate is also provided with several coarse guide components, which form a defined area of ​​the automotive radar bracket.

[0013] Furthermore, the coarse guide assembly includes a base and a guide rod, the guide rod is fixed on the base, the base is provided with an oblong hole, and the base is fixed to the base plate by bolts.

[0014] Furthermore, the end of the guide rod is provided with a frustum-shaped structure.

[0015] The beneficial effects achieved by this utility model are:

[0016] This invention uses three sets of main clamping components to determine the reference position, and several auxiliary clamping components to clamp and fix the component, preventing deformation of thin-walled parts such as automotive radar brackets during clamping, thus ensuring the accuracy of machining hole position and size deviations. A support cylinder is set in the middle to support the weak points of the automotive radar bracket, further improving the stability of the automotive radar bracket during machining.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] A machining fixture for an automotive radar bracket, such as Figures 1-6 As shown, the system includes a base plate 1, main clamping components 2, auxiliary clamping components 3, and elastic positioning pins 4. Two elastic positioning pins 4 are provided, corresponding to the reference holes on opposite sides of the car radar bracket, for positioning the car radar bracket. Three sets of main clamping components 2 are provided, arranged in a triangular pattern, with each main clamping component 2 clamping one side of the car radar bracket. Several auxiliary clamping components 3 are provided, which can be added or removed according to actual needs. After the main clamping components 2 have completed clamping, the auxiliary clamping components 3 provide additional clamping to the edges of the car radar bracket.

[0025] In one embodiment, such as Figures 1-6 As shown, the main clamping assembly 2 includes a support base 21 and a first lever cylinder 22. The support base 21 supports the car radar bracket, and the first lever cylinder 22 presses the car radar bracket onto the support base 21. In this embodiment, three sets of active clamping assemblies 2 form a positioning plane. The clamping planes of the three sets of main clamping assemblies 2 are parallel to each other. The lever cylinder is selected so that it is away from the clamping position when opened, avoiding interference with the placement and removal of the car radar bracket.

[0026] In one embodiment, such as Figures 1-6 As shown, the auxiliary clamping assembly 3 includes a first push rod 31, a first hydraulic support cylinder 32, and a second lever cylinder 33. The first push rod 31 is mounted on the first hydraulic support cylinder 32, and the first push rod 31 is driven to move axially by the first hydraulic support cylinder 32. In use, the first push rod 31 is driven by the first hydraulic support cylinder 32 to move towards the car radar bracket. After contacting the car radar bracket, the first hydraulic support cylinder 32 stops and maintains its current position to support the car radar bracket. Then, the second lever cylinder 33 presses the car radar bracket onto the first push rod 31 to further clamp and fix the car radar bracket, ensuring the stability of the clamping.

[0027] In one embodiment, such as Figures 1-6 As shown, it also includes a support rod 5, which is set on the base plate 1. When the car radar bracket is placed, it is placed on the support seat 21 of the three main clamping components 2. However, the clamping points of the support seat 21 are not set arbitrarily, so it will tilt to one side after placement. By setting the support rod 5, it can be supported during placement, thereby preventing the car radar bracket from tilting excessively.

[0028] In the above embodiments, such as Figures 1-6 As shown, when the car radar bracket is in the clamped state, there is a gap between the support rod 5 and the car radar bracket. The support rod 5 cannot be height adjusted, therefore it cannot properly cooperate with the car radar bracket. By setting a gap, contact between the support rod 5 and the car radar bracket is avoided when the bracket is clamped.

[0029] In one embodiment, such as Figures 1-6 As shown, a second push rod 6 and a second hydraulic support cylinder 7 are also installed on the base plate 1. Specifically, the automotive radar bracket has a rectangular structure. The clamping points of the main clamping assembly 2 and the auxiliary clamping assembly 3 are located at the edges of the automotive radar bracket, while there are machining points in the middle part of the automotive radar bracket. In order to further improve the machining accuracy of the points, the second push rod 6 and the second hydraulic support cylinder 7 are installed to support the middle part of the automotive radar bracket. In addition, there are machining points at a corner of the automotive radar bracket. Therefore, the second hydraulic support cylinder 7 and the second push rod 6 are installed on one side of the machining point to ensure stability during machining.

[0030] In one embodiment, such as Figures 1-6 As shown, several coarse guide components 8 are also provided on the base plate 1, forming a defined area for the car radar bracket. This prevents the car radar bracket from being placed incorrectly and serves as a foolproof mechanism.

[0031] In the above embodiments, such as Figures 1-6 As shown, the coarse guide assembly 8 includes a base 81 and a guide rod 82. The guide rod 82 is fixed on the base 81, and the base 81 is provided with an oblong hole 83. The base 81 is fixed to the base plate 1 by bolts. A single bolt is used for fixing, allowing the guide rod 82 to rotate around the bolt to adjust its position. The oblong hole allows the guide rod 82 to adjust its position along the guiding direction of the oblong hole.

[0032] In one embodiment, such as Figures 1-6 As shown, the end of the guide rod 82 is provided with a truncated cone structure. The side of the truncated cone guides the placement of the automotive radar bracket.

[0033] When using this utility model, such as Figures 1-6 As shown, the car radar bracket is placed within the range defined by the coarse guide assembly 8, and the two reference holes on the car radar bracket are aligned with the elastic positioning pin 4 before placement. The car radar bracket is supported by the support base 21 and the support rod 5. Then, the equipment is started, and the first lever cylinder 22 presses the car radar bracket onto the support base 21. At this time, the car radar bracket separates from the support rod 5. Then, the first hydraulic support cylinder 32 drives the first push rod 31 to rise. When it contacts the car radar bracket, it stops moving, and the second lever cylinder 33 actuates, pressing the car radar bracket onto the first push rod 31. Then, the second hydraulic support cylinder 7 drives the second push rod 6 to rise, so as to support the middle part of the car radar bracket.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
