Embedded small-size toad pincers side top universal fixturing of integration

Technical Field

The utility model relates to a processing frock field, concretely relates to small-size toad pincers side top universal fixturing of embedded integration.

Background

The toad clamp is a universal clamp and is commonly used for mounting small workpieces. It is a random accessory of milling machine and drilling machine. The clamping device is fixed on a machine tool workbench and is used for clamping a workpiece for cutting. The working principle is that the toad clamp base is connected with the trapezoidal groove platform through the trapezoidal block, and the large-distance adjustment of horizontal displacement is achieved. An inner hexagonal wrench is used for rotating the adjusting bolt, and a screw pair of the adjusting bolt drives the front end sliding block to move up and down on the base along the inclined plane to realize small-distance adjusting horizontal displacement, so that clamping and loosening of the workpiece are completed.

The assembly structure of the toad clip is in detachable threaded connection; the movement of the slide block along the inclined plane is converted from spiral movement; the working surface is the friction surface of screw pair, guide rail pair and clearance fit shaft and hole. The toad clamp has simple composition and compact structure, and the specific structure mainly comprises a jaw block, a toad clamp sliding block, an adjusting bolt and a toad clamp base.

When the workpiece is clamped, the horizontal clamping force is decomposed along the inclined plane where the adjusting bolt is located, a component force perpendicular to the inclined plane and a component force downward along the inclined plane can be obtained, and the component force downward along the inclined plane can prevent the front end sliding block from tilting upwards in the process of clamping the workpiece. Due to the special advantages of the clamp, the common toad clamp is actively and reversely designed by related technicians in the domestic machining industry on the basis of the advanced manufacturing experience at abroad. The Chinese patent with the application number of 202121897870.5, which is applied at present, discloses a pair of frog clamp for fixing machining materials, which comprises a shell mechanism, wherein a clamping mechanism used for clamping workpieces is installed in the shell mechanism, the shell mechanism comprises a first half shell and a second half shell, sliding grooves are formed in two sides, close to each other, of the first half shell and the second half shell, half grooves are formed in the top ends, located on the sliding grooves, of the first half shell and the second half shell, a positioning block is arranged at the position, corresponding to the half grooves, of the bottom end of the first half shell, and a second threaded hole is formed in the top end of the positioning block; fixture includes the clamp splice, just the clamp splice is the T style of calligraphy, and the bar groove has been seted up to long limit one side of clamp splice, and the clamp splice is sliding connection through half shell of spout and first and half shell and second, and the one end that the clamp splice is located the spout is provided with the ejector pad, and the top of ejector pad runs through along vertical direction and is provided with adjusting screw, just adjusting screw's bottom is threaded connection with the second screw hole.
