Description

Technical Field

[0001] The utility model relates to the technical field of pressing, in particular to a pressing device for covering the surface of a trunk cover of an automobile. Background Art

[0002] The cover plate used to pave the trunk of a car is used to separate the spare tire and tool layer at the bottom. In order to ensure the appearance of the cover plate, it is necessary to cover the surface of the cover plate. Cloth is covered on the surface of the cover plate with glue, and then the glue is dried. However, in this process, some edges of the cloth will be lifted up and cannot be completely adhered, resulting in damage to the cloth covering after a period of use. The clamping device used in the prior art uses clamps to operate pressure rods on all sides of the device to press the cover plate. The operation is frequent and the processing efficiency is low. In view of this problem, the utility model proposes the following improvements. Utility Model Content

[0003] The utility model aims to provide a pressing device for covering the surface skin of a trunk cover of an automobile, which has the effect of improving work efficiency.

[0004] The above technical purpose of the utility model is achieved through the following technical scheme: a clamping device for covering the surface of a car trunk cover, comprising a workbench, pressure rods are slidably connected to the top of the workbench on all four sides, a cylinder is installed on the top of the workbench, a driving plate is fixedly connected to the piston end of the cylinder, and the plurality of pressure rods are fixedly connected to the driving plate. The cylinder is used to press the pressure rod against the surface of the workbench, an arc is provided on one side of the workbench, and a pressing roller is rotatably provided on the pressure rod corresponding to the arc side.

[0005] By adopting the above technical scheme, a cylinder and a pressure rod are set, the cylinder drives the pressure rod to move downward and press the pressure rod against the workbench, a cover plate is placed on the workbench, and the pressure rod presses the four sides of the cover plate until the glue cools and solidifies, thereby achieving the purposes of simple operation and high operating efficiency; because the edge of the trunk cover plate of a car has an arc-shaped setting, the arc-shaped edge is placed on the arc-shaped edge of the workbench when the cover plate is placed, and by setting a pressing roller, when the pressure rod is pressed downward, the pressing roller presses the arc-shaped flipped part of the cover plate against the workbench, thereby achieving the purpose of firmly gluing the surface of the arc-shaped flipped part of the cover plate.

[0006] The utility model is further configured as follows: the workbench is vertically provided with a guide rod for the pressure rod to slide, the workbench is provided with a buffer platform around it, the pressure rod is provided with a buffer block, and a spring is connected between the pressure rod and the buffer block.

[0007] The utility model is further configured as follows: the buffer block is located below the plane of the pressure rod.

[0008] By adopting the above technical solution, a guide rod is set, and the guide rod is fixed on the buffer platform. When the cylinder drives the pressure rod to move downward, the buffer block contacts the buffer platform first. After the buffer block contacts the buffer platform, the cylinder continues to drive the pressure rod to move downward. Due to the different thicknesses of the edges of the cover plates, and because the pressure rods move downward together, the pressure rods descend to different heights when encountering cover plates of different thicknesses, thereby achieving the purpose of the pressure rod being able to press edges of different heights.

[0009] The utility model is further configured as follows: a pressing plate is horizontally slidably connected to one side of the pressing rods that are close to each other, and the bottom surface of the pressing plate is in the same horizontal plane as the bottom surface of the pressing rods.

[0010] By adopting the above technical solution and setting a pressure plate, for some cover plates with loose surface covering, the pressure plate in the pressure rod can be pulled out and pressed on the surface of the cover plate. Since the pressure rod is designed to be narrow, it can only press the edge of the cover plate. In the case of loose adhesion or too much glue, a pressure plate is needed to increase the contact area, thereby achieving the purpose of selectively setting the pressing area.

[0011] The utility model is further configured as follows: the pressure rod is threadedly connected with a bolt, the bolt is passed through the pressure rod, and the end of the bolt away from the pressure rod is rotatably connected to the pressure plate.

[0012] By adopting the above technical solution and setting bolts, when the pressure plate needs to be pulled out from the pressure rod and the cover plate needs to be pressed, it is only necessary to turn the bolts, and the bolts drive the pressure plate to slide on the pressure rod, and the bolts can ensure the stability of the sliding and connection of the pressure plate.

[0013] The utility model is further configured as follows: a bearing is provided between the bolt and the pressure plate.

[0014] By adopting the above technical solution and setting a bearing, when the bolt rotates on the pressure rod, the position of the bolt on the pressure rod changes. At this time, the bolt moves on the pressure rod. Through the bearing, the pressure plate does not need to rotate with the bolt, but moves with the bolt.

[0015] The utility model is further configured as follows: the pressure rod is provided with an active cavity for the pressure plate to slide, both sides of the active cavity are provided with sliding grooves for the pressure plate to slide, and both ends of the pressure plate are embedded in the sliding grooves.

[0016] By adopting the above technical solution and providing a sliding groove, the purpose of slidingly connecting the pressure plate to the pressure rod can be achieved.

[0017] The utility model is further configured as follows: a handle is fixedly provided at the end of the bolt away from the pressing plate.

[0018] By adopting the above technical solution and providing a handle, when it is necessary to adjust the position of the pressure plate on the pressure rod, it is only necessary to rotate the bolt through the handle, thereby achieving the purpose of convenient operation.

[0019] The utility model is further configured as follows: a pressure rod corresponding to the arc-shaped edge is hinged with a connecting rod, the pressing roller is rotatably connected to the connecting rod, and a coil spring is connected between the connecting rod and the pressure rod.

[0020] By adopting the above technical solution, a connecting rod is set, and under normal conditions, the angle between the connecting rod and the pressure rod is kept constant under the action of the second spring. When the pressing roller is pressed to the arc of the workbench under the drive of the pressure rod, the pressing roller rolls at the arc to reduce friction, and the angle between the connecting rod and the pressure rod changes under extrusion, and the coil spring rotates under force. When the pressing is completed, the pressing roller leaves the arc of the workbench, and the coil spring restores the angle between the connecting rod and the pressure rod, thereby achieving the purpose of automatically adjusting the pressing roller according to the curvature of the cover plate.

[0021] The utility model is further configured as follows: the outer ring of the pressing roller is provided with elastic material.

[0022] By adopting the above technical solution, the purpose of reducing the friction between the pressing roller and the cover plate can be achieved.

[0023] The beneficial effects of the utility model are:

[0024] 1. The cylinder drives four pressure rods to move downward at the same time through the driving plate. Since the heights of the cover edges are not equal, when the pressure rods are pressed down, the springs will contract according to the situation to ensure that covers with different edge thicknesses can be pressed.

[0025] 2. For cover plates with loose surface covering, the position of the pressure plate can be adjusted by bolts to widen the force-bearing area of ​​the cover plate, which is selective.

[0026] 3. For covers with different edge curvatures, the angle can be automatically adjusted through coil springs, pressing rollers and connecting rods. BRIEF DESCRIPTION OF THE DRAWINGS
