Detailed Description

The following description of the preferred embodiments of the present invention will be made in conjunction with the accompanying drawings.

Referring to fig. 1-2, in order to provide the square product clamping and positioning device of the present invention, the device comprises a device bottom plate 1, three supporting and leaning columns 2 with the same height and a movable fourth supporting column 3 are arranged on the upper side surface of the device bottom plate 1, and the three supporting and leaning columns 2 and the fourth supporting column form a four-point supporting structure; an adjusting cylinder 4 is fixed on the lower side surface of the device bottom plate 1, the lower end of the fourth supporting column 3 is fixedly connected with a piston rod of the adjusting cylinder, and the adjusting cylinder can drive the fourth supporting column 3 to move up and down relative to the device bottom plate; the four-point supporting device is characterized in that four pressing cylinders 5 are further arranged on the outer side of the four-point supporting structure on the upper side face of the device bottom plate 1, the tail end of a piston rod of each pressing cylinder is connected with a pressing block 6, the pressing cylinders 5 can drive the pressing blocks 6 to move up and down, and the four pressing blocks form a four-point pressing structure.

When the square product clamping and positioning device is used, firstly, a product 10 to be processed is placed on the three bearing columns 2, and three-point support is formed on the bottom of the product; then, starting the four pressing cylinders 5 to drive the four pressing blocks 6 to move downwards, and pressing the four pressing blocks at the four corners of the upper side surface of the product to form four-point pressing; and then, starting the adjusting cylinder 4 to drive the fourth supporting column 3 to jack upwards, and automatically locking after contacting the product to form a fourth bearing. The four-point pressing structure of the bottom four-point support and the top surface is formed, the product is pressed and positioned, the technical problem that the product machining precision is affected due to the fact that the bottom flatness of the product caused by machining deformation is poor, four bearing columns cannot be in contact with the product to support the product, and the product is shaken during machining is avoided, so that the real four-point support is formed, the product is stably clamped and positioned, and the product machining precision is ensured.

The upper side surface of the device bottom plate 1 is provided with two bearing columns and auxiliary supporting columns 7 are arranged between the bearing columns and the fourth supporting column 3 respectively, the auxiliary supporting columns are elastic supporting columns, supporting force of the three bearing columns and the supporting force of the fourth supporting column can be further shared, and weight of a product capable of being borne is improved, and the service life of the product capable of being borne is prolonged.

The pressing block is horizontally arranged, and a guide assembly used for limiting the pressing block to move along the vertical direction is arranged between the pressing block and the base of the pressing cylinder 5, so that the accuracy of the pressing block in up-and-down movement is prevented, and the accuracy of the pressing position is ensured. In addition, the tail end of the pressing block is provided with a rubber pressing head 61, so that the surface of a product is prevented from being pressed when the product is contacted, and the product is protected.

Therefore, the square product clamping and positioning device has the advantages that the existing four-point supporting structure is replaced by the adjustable support of the three-point bearing leaning column support and the fourth supporting column, so that the stable four-point support and four-point pressing and holding structure is formed, the stability of clamping and positioning of the product is ensured, the product cannot shake due to product deformation or poor flatness, the subsequent processing precision of the product is guaranteed, and the square product clamping and positioning device has the advantages of simple structure, convenience in operation, high processing efficiency, high product processing quality and the like.
