Problems solved by technology

[0004] 1. The distance between the two clamping sleeves is fixed. When the number of cylinders and the distance between each cylinder of different car models are different, it is necessary to replace the matching grippers, resulting in each The usage rate of the claws is low and the adaptability is poor
[0005] 2. Since the radial distance of the friction block protruding from the clamping sleeve is the same, and the friction block is composed of a rubber block with certain elasticity, when it is necessary to clamp the engine block with different cylinder inner diameters, the elastic deformation of the friction block will The amount will be inconsistent, resulting in different locking forces for cylinders with different inner diameters, and it is impossible to clamp and transport various types of engine cylinders with the best locking force
[0007] 4. When the two clamping sleeves on the claw extend into the cylinder and clamp the cylinder, the two friction blocks exert a squeezing force on the inner wall of the cylinder through elastic deformation, so the connecting sleeve or The central axis of the connecting rod and the cylinder is prone to deviation, and it is difficult to keep the central axis coincident all the time, resulting in inaccurate positioning of the subsequent engine cylinder and affecting the handling accuracy

Embodiment 2

[0045] see Figure 6-Figure 7The difference between this embodiment and Embodiment 1 is that there are two groups of the plurality of guide grooves 10, and the inclination directions of the two groups of guide grooves 10 are opposite; the plurality of telescopic blocks 4 have two groups, and respectively Correspondingly arranged on the two groups of guide grooves 10, the radiuses of the arc surfaces of the two groups of telescopic blocks 4 are different. The advantage of this scheme is that the claw mechanism can adapt to two different types of engine cylinders, especially for engine cylinders with inconsistent cylinder inner diameters; Under the guidance of two sets of guide grooves 10 with opposite inclination directions, two sets of telescopic blocks 4 perform opposite telescopic movements, so that each set of telescopic blocks 4 can be matched with the corresponding cylinder, and can match the inner wall of the cylinder when clamping , The arc surface of the telescopic bl...

Embodiment 3

[0047] The difference between this embodiment and Embodiment 1 is that the position adjustment drive mechanism 9 is composed of a motor and a screw drive mechanism, the lead screw of the lead screw drive mechanism is connected to the main shaft of the motor, and the lead screw drive mechanism The leading screw nut is connected with the corresponding movable seat 3; along the moving direction of the movable claw mechanism, an adjusting spring is arranged between the front and rear sides of the movable seat 3 and the leading screw nut. The movable seat 3 is driven to move by means of a screw transmission mechanism, which can control the movable seat 3 to move to various positions in the lateral direction, thereby being able to adapt to more engine blocks of different types, and has wider adaptability; in addition, when the connecting sleeve 6 After moving into the cylinder, the telescopic drive mechanism 1 drives the drive rod 11 to move downward, so that a plurality of telescopi...

Embodiment 4

[0049] see Figure 8-Figure 9 , the support plate 5 includes a horizontally arranged intermediate connecting plate 13 and two obliquely arranged fixed installation presses 12, and the two fixed installation presses 12 are respectively connected to both sides of the intermediate connecting plate 13; the connecting seat 2 is set On the middle connecting plate 13, the two grabbing components are respectively arranged on the two fixed mounting buttons 12. By arranging such a support plate 5, the two grasping components are all obliquely arranged on the support plate 5; on the processing line of the automobile engine, some stations need to arrange the automobile engine obliquely, and through the inclined grasping assembly Compatible with the cylinder bores of these automobile engines for easy clamping and handling.

Abstract

The invention discloses an intelligent truss with a universal tongs structure. A guide rail, a walking mechanism arranged on the guide rail and tongs are included. The tongs comprise a support plate and a grabbing assembly arranged on the support plate, and the support plate is connected with the walking mechanism on the guide rail. The grabbing assembly comprises two hand claw mechanisms. Each hand claw mechanism comprises a connecting sleeve, a drive rod, a plurality of telescopic blocks and a telescopic drive mechanism driving the drive rod to move up and down, wherein the drive rod is arranged in the connecting sleeve, the drive rod is provided with a plurality of guiding grooves obliquely arranged in the radial direction, the multiple telescopic blocks are arranged in the circumference direction, one end of each telescopic block is in sliding connection into the corresponding guiding groove, the connecting sleeve is provided with avoiding holes for avoiding the stretching-out or retracting movement of the telescopic blocks, and the other ends of the telescopic blocks are supported on the avoiding holes. The intelligent truss can be applicable to clamping and carrying of different types of engine cylinders, and positioning is accurate.

Description

technical field [0001] The invention relates to an automobile engine cylinder block handling device, in particular to an intelligent truss with a universal gripper structure. Background technique [0002] In the processing and production process of the automobile engine cylinder block, it is necessary to transport the cylinder block to different stations for various processing. The general handling equipment is composed of a truss and a grabbing mechanism arranged on the truss; The appearance structure is complex and irregular, so during the handling process, the two claws on the grabbing mechanism take two of the cylinders on the cylinder as the clamping targets respectively, and extend into the cylinder, so as to facilitate the adjustment of the cylinder. Clamping; at the same time, in order to facilitate the positioning of the cylinder between the two stations, the two claws on the grabbing mechanism are used as the positioning points during the handling process. [0003...
