Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle body transfer equipment and relates to a retractable sliding frame of a chassis upper and lower parts lifter. Background Art
[0002] At present, the domestic car model competition is fierce, and different models with large wheelbase differences (such as A0-class and B-class cars) will be produced on the same production line. Automobile factories need to switch models at any time according to market conditions. Due to the different wheelbases of the models, the spacing after the front and rear supports are also different. The existing rear support adjustment is completed by the cylinder, and the adjustment spacing of the cylinder is fixed and cannot be adjusted at will, resulting in fewer models that meet the requirements.
[0003] The width of the skirts of different models is different. The batteries at the bottom of many new energy models are lower than the skirts, so the support blocks supporting the skirts cannot extend too far under the car. The existing rear support assembly uses two sliders running on the slide rails. The sliders have a large bearing capacity, resulting in an unstable structure. Summary of the invention
[0004] In view of the above problems, the utility model provides a retractable slide frame of a chassis upper and lower parts lifter. The adjustment spacing range of the retractable slide frame is relatively wide and can be applicable to various vehicle models.
[0005] According to the technical solution of the utility model: a retractable slide for a chassis upper and lower parts lift, characterized in that: it includes a slide fixing frame, a front support assembly is installed at one end of the slide fixing frame, and a rear support assembly is arranged at the other end of the slide fixing frame, and the rear support assembly can slide on the slide fixing frame under the drive of the sliding drive assembly to adjust the distance between the rear support assembly and the front support assembly, and the sliding drive assembly is installed on the slide fixing frame;
[0006] The front support frame of the front support assembly and the rear support frame of the rear support assembly can both be adjusted in position to accommodate a variety of vehicle models;
[0007] The guide wheel is installed on the slide fixing frame to realize the up and down movement of the slide fixing frame on the elevator column surface.
[0008] As a further improvement of the utility model, two parallel first linear slide rails are installed on the slide fixing frame, and the rear support frame of the rear support assembly is respectively installed with two sliders corresponding to each of the first linear slide rails to slide with the corresponding first linear slide rails.
[0009] As a further improvement of the utility model, the front support assembly also includes a second linear slide rail, a front movable support, and a first single-rod double-acting cylinder. The front support frame is slidingly connected to the front movable support through the second linear slide rail. The first single-rod double-acting cylinder is installed on the front movable support, and the first single-rod double-acting cylinder can drive the front support frame to move on the second linear slide rail.
[0010] As a further improvement of the utility model, the rear support assembly also includes a rear movable support, a signal rod, a rack, a third linear slide rail, and a second single-rod double-acting cylinder. The rear support frame is slidingly connected to the rear movable support through the third linear slide rail. The second single-rod double-acting cylinder is installed on the rear movable support, and the second single-rod double-acting cylinder can drive the rear support frame to move on the third linear slide rail. The signal rod is installed on the rear support frame, and the rack is installed on the rear support frame.
[0011] As a further improvement of the utility model, the sliding drive assembly includes a motor and a gear mounted on the output shaft of the motor, and the gear is meshed with the rack of the rear support assembly.
[0012] As a further improvement of the utility model, a switch is installed on the slide fixing frame to control the distance when the rear support assembly moves forward and backward.
[0013] The technical effect of the utility model is that the product structure of the utility model is reasonable and ingenious. In view of the problem that the wheelbase of different models is different, the spacing between the front and rear supports after adjustment is also different; the application adopts motor gear rack for adjustment, so that the distance of the rear support can be adjusted at will within the maximum and minimum spacing to meet the needs of the new model after transformation. At the same time, the application adopts a single-rod double-acting cylinder to meet the needs of the skirt support position when switching between different models during the production process.
[0014] The rear support frame is improved to have 4 sliders running on linear guide rails. Each slider has less load. And 4 sliders fix one frame, making the rear support assembly structure more stable. BRIEF DESCRIPTION OF THE DRAWINGS
