Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of automobile production and manufacturing equipment, and particularly relates to a horizontal switching fixed-point positioning device for automobile door covers of multiple models. BACKGROUND
[0002] In order to save cost and space, an automobile factory often produces multiple models on one production line. In particular, the door cover production line, due to the size difference of door covers of different models or slight changes caused by distinguishing model plates, leads to changes in the supporting and pressing parts, and different positioning and grabbing devices are used for different models. This involves multiple sets of devices switching with models through a turntable or a robot, resulting in more space occupied in the workshop, heavy equipment, reduced production efficiency, replacement of heavy-load robots, and increased investment cost. SUMMARY
[0003] The utility model aims to provide a horizontal switching fixed-point positioning device for automobile door covers of multiple models to solve the problems in the background art.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a horizontal switching fixed-point positioning device for automobile door covers of multiple models, comprising a stepping transmission mechanism, a support seat, a first connecting plate, a first universal head, a second universal head, a second connecting plate, a connecting plate assembly, and a cylinder, the first connecting plate is connected with the movable end of the stepping transmission mechanism through the support seat, the first universal head is fixed on one side of the top of the first connecting plate, the second universal head is fixed on one side of the bottom of the second connecting plate, the first universal head and the second universal head correspond, the two ends of the connecting plate assembly are hinged with the first connecting plate and the second connecting plate respectively, the piston rod of the cylinder is hinged with the other side of the second connecting plate, and the cylinder body of the cylinder is hinged with the side of the first connecting plate through a hinge shaft.
[0005] Preferably, the stepping transmission mechanism is a moving module.
[0006] Preferably, one side of the first connecting plate is fixed with a support, and a sensor is fixed on the support.
[0007] The utility model has the advantages of: 1. Reduced manufacturing cost and saved space, the device realizes the grabbing of multiple models of different structures by one set of grabber, and traditional mechanisms need multiple grabbers to achieve this, which reduces the manufacturing cost of the grabber and the grabber storage device, and saves the space occupied by the traditional grabber and the grabber storage device.
[0008] 2. Improved work efficiency, traditional mechanisms need to switch grabbers through a robot to realize the taking and placing of different model plates, which takes a lot of time, and the device can quickly realize the model switching function through the motor-driven stepping mechanism.
[0009] 3. Use small-load robots to reduce robot procurement costs. Traditional mechanisms can achieve a small number of models sharing a single gripper by clamping different positions of different vehicle body panels. However, due to the large number of clamping units and the complex structure, the weight of the gripper increases significantly, thus requiring the use of robots with larger loads, which leads to increased robot costs. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the overall three-dimensional structure of this utility model. Detailed Implementation
[0011] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.
[0012] like Figure 1 As shown, a multi-model car door cover horizontal switching positioning device includes a stepping conveyor mechanism 1, a support base 2, a first connecting plate 3, a first universal joint 8, a second universal joint 9, a second connecting plate 6, a connecting plate assembly 7, and a cylinder 11. The first connecting plate is connected to the movable end of the stepping conveyor mechanism via the support base. The stepping conveyor mechanism drives the first connecting plate to move via the support base. The first universal joint is fixed to one side of the top of the first connecting plate, and the second universal joint is fixed to one side of the bottom of the second connecting plate, corresponding to each other. The two ends of the connecting plate assembly are respectively hinged to the first and second connecting plates. The piston rod of the cylinder is hinged to the other side of the second connecting plate, and the cylinder body is hinged to the side of the first connecting plate via a hinge shaft. The piston rod of the cylinder, the first connecting plate, the connecting plate assembly, and the second connecting plate form a four-bar linkage. When the piston rod of the cylinder moves, it drives the second connecting plate to move, and the second connecting plate drives the upper second universal joint to move, together with the first universal joint, to achieve a clamping action.
[0013] In this device, the stepping transmission mechanism is a moving module, which is driven by a motor 10. A bracket 4 is fixed to one side of the first connecting plate, and a sensor 5 is fixed on the bracket. When the robot moves this device to the vicinity of the plate, the sensor 5 detects a signal from the plate, the cylinder 11 tightens, and the first universal joint 8 and the second universal joint 9 clamp the plate. The plate can be picked up and placed by using multiple devices.
[0014] The stepper transmission mechanism 1, controlled by motor 10, drives the support base 2 and all connected parts to move back and forth, thereby clamping and gripping different plates.
[0015] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
