Description

Technical Field

[0001] This utility model relates to the technical field of reference zeroing devices for automotive sheet metal parts, specifically a reference zeroing device for automotive sheet metal parts. Background Technology

[0002] When measuring automotive sheet metal parts with a fixture, several relatively flat surfaces or surfaces with small springback after stamping are usually selected as reference surfaces for the parts. These surfaces are fixed or adjusted to their theoretical positions, and then other inspection surfaces or trimming is performed to determine whether the sheet metal parts are qualified.

[0003] However, the existing zeroing process requires multiple disassembly and reassembly of the device to zero the calibration tool, which prolongs the single measurement cycle and cannot meet the needs of batch testing. Utility Model Content

[0004] The purpose of this utility model is to provide a reference zeroing device for automotive sheet metal parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A reference zeroing device for automotive sheet metal parts includes a mounting plate. A digital dial indicator for inspecting the sheet metal parts is inserted into one side of the mounting plate. A connector for connecting to a fixture body is provided at the bottom of the mounting plate. A rotating component is provided in the middle of the mounting plate for rotating the mounting plate to rotate the testing end of the digital dial indicator to the outside of the fixture. Positioning components are provided at the bottom of both sides of the mounting plate to ensure the positioning accuracy of the mounting plate.

[0007] As a preferred technical solution, the connector includes a mounting base disposed at the lower part of the mounting plate, with second screws inserted into the top of both sides of the mounting base. Two sets of the second screws penetrate the mounting base and are connected to the fixture body, and the screw heads of the two sets of the second screws are flush with the top of the mounting base.

[0008] As a preferred technical solution, the rotating component includes a first screw disposed at the lower part of the mounting base. The screw shaft rotates upward sequentially through the mounting base and the mounting plate and is threadedly connected to a star-shaped handle. The bottom of the star-shaped handle abuts against the bottom of the mounting plate. The step of the screw shaft abuts against the surface of the mounting plate. The neck of the first screw is provided with a pusher that pushes the end of the first screw downward.

[0009] As a preferred technical solution, the pushing member includes a compression spring sleeved on the neck of the first screw, with the two ends of the compression spring contacting the bottom of the mounting base and the end surface of the first screw, respectively.

[0010] As a preferred technical solution, the positioning component includes a main positioning pin and a secondary positioning pin disposed at the bottom of both sides of the mounting plate. A third screw is inserted into the top of both sides of the mounting plate at the positions of the main positioning pin and the secondary positioning pin. The two sets of third screws are threadedly connected to the corresponding main positioning pin and the secondary positioning pin.

[0011] As a preferred technical solution, the probe end of the digital dial indicator is fitted with a washer, the bottom of the washer contacts the top of the mounting plate, and a fourth screw for abutting the digital dial indicator is threaded onto one side of the mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. With the addition of a rotating component, the operator can easily rotate the mounting plate by pulling and turning the star-shaped handle, thereby adjusting the position of the digital dial indicator's detection end. This allows for flexible rotation of the mounting plate, enabling the digital dial indicator's detection end to be rotated to the outside for zeroing operations. This allows the digital dial indicator to flexibly switch between the zeroing pad and the sheet metal part without the need for multiple disassembly and reassembly of the device.

[0014] 2. By incorporating a compression spring, this utility model allows the spring to push the end of the first screw downwards during the rotation of the mounting plate. This assists the star-shaped handle in rotating the mounting plate and resetting it, ensuring that the mounting plate can quickly and stably return to its original position after rotation. This reduces manual adjustment steps, improves operational efficiency, and enhances the stability and reliability of the rotating structure.

[0015] 3. This utility model, through the setting of the positioning component, ensures that the positioning component maintains precise positioning during the rotation of the mounting plate, preventing the reference from failing due to mounting plate misalignment. Even with multiple switching of detection positions, there is no need to readjust the mounting plate position, effectively avoiding repeated zeroing, ensuring a consistent measurement reference for each measurement, and significantly improving the efficiency and accuracy of batch testing.

[0022] 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.

[0023] Please see Figure 1-4 This embodiment provides a reference zeroing device for automotive sheet metal parts, including a mounting plate 2. A digital dial indicator 7 for inspecting sheet metal parts 14 is inserted into one side of the mounting plate 2. A connector for connecting to the fixture body is provided at the bottom of the mounting plate 2. A rotating component is provided in the middle of the mounting plate 2 for rotating the mounting plate 2 to rotate the inspection end of the digital dial indicator 7 to the outside of the fixture. Positioning components are provided at the bottom of both sides of the mounting plate 2 to ensure the positioning accuracy of the mounting plate 2.

[0024] The rotating component includes a first screw 4 located at the lower part of the mounting base 1. The screw 4 rotates upwards through the mounting base 1 and the mounting plate 2 and is threadedly connected to a star-shaped handle 8. The bottom of the star-shaped handle 8 abuts against the bottom of the mounting plate 2, and the step of the screw 4 abuts against the surface of the mounting plate 2. The neck of the first screw 4 is provided with a pusher that pushes the end of the first screw 4 downwards. With the rotating component, the operator can easily rotate the mounting plate 2 by pulling and rotating the star-shaped handle 8, thereby adjusting the position of the digital dial indicator 7's detection end. This allows for flexible rotation of the mounting plate 2, moving the digital dial indicator 7's detection end to the outside for zeroing operations. This enables the digital dial indicator 7 to flexibly switch between the zeroing pad and the sheet metal part 14 without multiple disassembly and reassembly of the device.

[0025] Among them, the dial indicator zeroing pad 13 used for calibrating the digital dial indicator 7 is installed on the top outer side of the fixture body and is located on the outside or side of the rotation path of the digital dial indicator 7 detection end, so as to ensure that the meter head can be contacted with the zeroing pad for zeroing before testing by rotating the mounting plate 2.

[0026] The connector includes a mounting base 1 located at the bottom of the mounting plate 2. Two second screws 12 are inserted into the top of both sides of the mounting base 1. The two sets of second screws 12 penetrate the mounting base 1 and are connected to the fixture body. The screw heads of the two sets of second screws 12 are flush with the top of the mounting base 1. Through the connector, the second screws 12 penetrate the mounting base 1 and are connected to the fixture body. The connection is stable and reliable. At the same time, the screw heads of the second screws 12 are flush with the top of the mounting base 1, avoiding interference with other components or operations. This ensures that the structure of the mounting plate 2 is flat after it is connected to the fixture, without affecting the overall testing process and equipment operation.

[0027] The pushing component includes a compression spring 3 sleeved on the neck of the first screw 4. The two ends of the compression spring 3 contact the bottom of the mounting base 1 and the end surface of the first screw 4, respectively. With the compression spring 3, during the operation of rotating the mounting plate 2, the compression spring 3 can push the end of the first screw 4 downward, and the auxiliary star handle 8 drives the mounting plate 2 to rotate and then reset, ensuring that the mounting plate 2 can quickly and stably return to its original position after rotation, reducing manual adjustment steps, improving operating efficiency, and enhancing the stability and reliability of the rotating structure.

[0028] The positioning components include main positioning pins 10 and auxiliary positioning pins 11 located at the bottom of both sides of the mounting plate 2. Third screws 9 are inserted into the top of both sides of the mounting plate 2 at the positions of the main positioning pins 10 and auxiliary positioning pins 11. The two sets of third screws 9 are threadedly connected to the corresponding main positioning pins 10 and auxiliary positioning pins 11. Through the positioning components, the positioning components maintain precise positioning during the rotation of the mounting plate 2, preventing reference failure due to mounting plate 2 offset. Even with multiple switching of testing positions, there is no need to readjust the position of the mounting plate 2, effectively avoiding repeated zeroing, ensuring consistent measurement reference for each measurement, and significantly improving the efficiency and accuracy of batch testing.

[0029] The digital dial indicator 7 has a washer 5 fitted on its probe end. The bottom of the washer 5 contacts the top of the mounting plate 2. A fourth screw 6 is threaded onto one side of the mounting plate 2 to abut against the digital dial indicator 7. The washer 5, with its bottom in contact with the top of the mounting plate 2, provides cushioning and support, protecting the probe end of the digital dial indicator 7 and extending its service life. At the same time, the fourth screw 6 abuts against the digital dial indicator 7, fixing its position on the mounting plate 2 and preventing it from shaking or shifting during testing, thus ensuring the accuracy and stability of the test data.

[0030] Working principle;

[0031] First, pull the star handle upwards and rotate it 90 degrees to expose the top sides of the mounting base 1. Then, use the second screw 12 to penetrate the mounting base 1 downwards and connect it to the fixture body. Next, pull the star handle upwards and rotate it 90 degrees in the opposite direction. At the same time, release the star handle, and the main positioning pin 10 and the secondary positioning pin 11 will be inserted into the top of the mounting base 1.

[0032] At this time, grab the star handle 8 with your right hand, pull it up, turn it 180 degrees backward, and slowly release it. Insert the main positioning pin 1010 and the auxiliary positioning pin 1111 into the mounting block 1. At the same time, the dial indicator 7's head contacts the dial indicator zeroing block 13 to zero the dial indicator pointer reading.

[0033] Furthermore, observe the reading of the digital dial indicator 7, and adjust the pointer or value to the "0" position. At this time, establish the theoretical zero point reference based on the position of the zero adjustment block.

[0034] Then, the sheet metal part 14 to be tested is installed onto the fixture body;

[0035] Grasp the star-shaped handle 8 again, pull it up and rotate it 180 degrees again, then slowly release it. Insert the main positioning pin 1010 and the secondary positioning pin 1111 into the mounting block 1. At the same time, the dial indicator 7 makes contact with the sheet metal part 14 to be tested. Adjust the sheet metal part 14 and zero the dial indicator reading. Then, start using other testing mechanisms on the inspection tool to test the accuracy of the sheet metal part 14.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
