The sensor component 1.3 is mounted on the mounting bracket 1.1 and is used to detect the counterweight.

[0044] See Figure 5 and Figure 6 The mounting bracket 1.1 includes a bracket body 1.1.1 and a bracket column 1.1.2. The bracket body 1.1.1 is mounted on the bracket column 1.1.2, and the bracket column 1.1.2 is mounted on the main body trolley 3.

[0045] The positioning component 1.2 includes a first positioning block 1.2.1 and a second positioning block 1.2.2; the first positioning block 1.2.1 is provided in two sets, and the two sets of first positioning blocks 1.2.1 are arranged opposite to each other along the length direction of the bracket body 1.1.1; the second positioning block 1.2.2 is arranged on one side of the bracket body 1.1.1 along the width direction of the bracket body 1.1.1, and the first positioning block 1.2.1 and the second positioning block 1.2.2 cooperate to position the accessory block 5.

[0046] In this embodiment, the support body 1.1.1 extends along both the transverse and longitudinal directions (with... Figure 5 Based on the view direction, multiple threaded holes are provided. Both the first positioning block 1.2.1 and the second positioning block 1.2.2 are provided with threaded holes. By adjusting the connection between the first positioning block 1.2.1 and the second positioning block 1.2.2 and the different threaded holes on the bracket body 1.1.1, the lateral and longitudinal positions of the first positioning block 1.2.1 and the second positioning block 1.2.2 can be adjusted.

[0047] See Figure 5 and Figure 6 The sensor assembly 1.3 includes a first sensor 1.3.1 and a second sensor 1.3.2. Both the first sensor 1.3.1 and the second sensor 1.3.2 are adjustablely mounted on the mounting bracket 1.1 via sensor brackets. The detection ends of the first sensor 1.3.1 and the second sensor 1.3.2 correspond to the mounting area of ​​the accessory block 5. The sensor bracket and the mounting bracket 1.1 are connected by screws. The mounting bracket 1.1 has multiple threaded holes. By adjusting the connection between the sensor bracket and the different threaded holes on the mounting bracket 1.1, the positions of the first sensor 1.3.1 and the second sensor 1.3.2 can be adjusted to meet the detection requirements of different workpieces.

[0048] The detection end of the first sensor 1.3.1 is flush with the surface of the mounting bracket 1.1 mounting accessory block 5 on one side, and is used to detect whether the accessory block 5 is installed in place; the detection end of the second sensor 1.3.2 protrudes from the surface of the mounting bracket 1.1 mounting accessory block 5 on one side; there are two sets of the second sensor 1.3.2, and the two sets of the second sensor 1.3.2 correspond one-to-one with the two threaded holes 5.2 on the accessory block 5.

[0049] In this embodiment, preferably, the first sensor 1.3.1 and the second sensor 1.3.2 are displacement sensors. Preferably, in this embodiment, the model of the first sensor 1.3.1 is E2E-X2D1-N, and the model of the second sensor 1.3.2 is E2E-C05S01-WC-C1.

[0050] See Figure 3 and Figure 4 The clamping device 2 includes a mounting frame 2.1, a clamping arm assembly 2.2, and a positioning pin 2.3; the mounting frame 2.1 is mounted on the main trolley 3, and the clamping arm assembly 2.2 and the positioning pin 2.3 are both disposed on the mounting frame 2.1.

[0051] The clamping arm assembly 2.2 includes a clamping arm 2.2.1 and a clamping cylinder 2.2.2. The clamping arm 2.2.1 is height-adjustable and is mounted on the mounting bracket 2.1. The clamping cylinder 2.2.2 is connected to the clamping arm 2.2.1 and is used to drive the clamping arm 2.2.1 to clamp and release the body component 4.

[0052] Preferably, the mounting bracket 2.1 is provided with a clamping arm adjusting block 2.4, which is used to adjust the installation height of the clamping arm 2.2.1 to meet the clamping requirements of workpieces of different heights.

[0053] See Figure 3 and Figure 4 The positioning pin 2.3 is mounted on the positioning pin bracket 2.5, which is adjustablely mounted on the mounting frame 2.1. Specifically, the positioning pin bracket 2.5 and the mounting frame 2.1 are connected by screws. The mounting frame 2.1 has multiple threaded holes along the horizontal and vertical directions. By adjusting the connection between the positioning pin bracket 2.5 and different threaded holes on the mounting frame 2.1, the position of the positioning pin bracket 2.5 can be adjusted, that is, the position of the positioning pin 2.3 can be adjusted. In this embodiment, the two positioning pins 2.3 of the two clamping devices 2 correspond one-to-one with the two positioning holes 4.1 of the body component 4.

[0054] In this embodiment, an electrical control system is also included to control the various electrical components to perform corresponding operations.

[0055] When assembling the counterweight, first install the accessory block 5 on the counterweight mounting device 1, and then install the main body 4 on the accessory block 5; see the image below for the correct installation status of accessory block 5. Figure 10 That is, the side of the accessory block 5 with the boss 5.1 faces upward and the flat side faces downward, and the side of the boss that is narrower from the edge of the accessory block 5 faces the second positioning block 1.2.2.

[0056] When component block 5 is installed in reverse, i.e., the side of component block 5 with boss 5.1 faces down and the flat surface faces up, see [reference]. Figure 6 and Figure 7 Because the boss 5.1 is in contact with the surface of the bracket body 1.1.1, there is a gap between the flat part of the accessory block 5 and the surface of the bracket body 1.1.1. The first sensor 1.3.1 cannot detect the accessory block 5, so it will not send a locking signal and the clamping device 2 will not clamp.

[0057] When component block 5 is placed in the wrong orientation, that is, the side of component block 5 with the larger distance from the edge of the boss faces the second positioning block 1.2.2, see [reference]. Figure 8 and Figure 9 Because the detection end of the second sensor 1.3.2 is misaligned with the threaded hole 5.2, the detection end of the second sensor 1.3.2 is not inserted into the threaded hole 5.2. The detection end of the second sensor 1.3.2 lifts up the accessory block 5, resulting in a gap between the plane of the accessory block 5 and the surface of the bracket body 1.1.1. The first sensor 1.3.1 cannot detect the accessory block 5, so it will not send a locking signal, and the clamping device 2 will not clamp.

[0058] The accessory block 5 is readjusted to ensure correct installation. The first sensor 1.3.1 detects the accessory block 5 and sends a signal. The electrical control system controls the clamping device 2 to clamp and position the main body 4. The screws are installed and tightened. At this time, the second sensor 1.3.2 detects whether the screws are tightened in place. If the tightening length of the screws does not meet the requirements, the clamping device 2 cannot be opened and the counterweight cannot be removed.

[0059] The automotive roof front crossbeam counterweight installation and clamping device provided by this utility model uses the counterweight installation device 1 and clamping device 2 to position and clamp the counterweight, achieving correct assembly of the counterweight. In particular, the first sensor 1.3.1 and the second sensor 1.3.2 are set to detect the counterweight, preventing product defects caused by reverse installation of the component block or loose installation screws, effectively avoiding the outflow of defective products and reducing the probability of customer complaints.

[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
