Fixing device for part

Abstract

The invention discloses a fixing device for a part. The fixing device comprises a bottom plate, a fixed clamping block, a movable clamping block and a pushing device, wherein the bottom plate is strip-shaped; the fixed clamping block is fixed at one end of the bottom plate; sliding grooves are formed in the two sides of the bottom plate in the length direction of the bottom plate; two sliding blocks respectively matched with the different sliding grooves are arranged on the movable clamping block; matching surfaces formed by the side surfaces of the sliding grooves and the bottom surfaces of the sliding blocks are arc-shaped surfaces; in the depth directions of the sliding grooves, the highest position points of the arc-shaped surfaces are positioned between the opening ends of the sliding grooves and the bottom ends of the sliding grooves; two sliding grooves are formed in each side of the bottom plate; the two sliding grooves positioned on the same side of the bottom plate are respectively positioned at the upper end and the lower end of the bottom plate; the widths of the upper end and the lower end of the bottom plate are not equal; and the fixed clamping block and the pushing device are detachably connected with the bottom plate. According to the fixing device, when the part is clamped, the uniformity of stress of all points on a clamping surface is facilitated, and the stability of the relative position of the fixed clamping block and the movable clamping block is facilitated; and the service life is long.

Description

technical field

[0001] The invention relates to the field of mechanical processing equipment, in particular to a component fixing device. Background technique

[0002] In the process of mechanical manufacturing, the device used to fix the processing object so that it occupies the correct position to accept construction or inspection is generally called a fixture, also known as a jig. In a broad sense, any process in the process of workpiece production, inspection or maintenance, the device used to quickly, conveniently and safely install the workpiece can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc.

[0003] In the prior art, a bench vise is a kind of universal fixture, and is an indispensable clamping device on a fitter's bench. Although the bench vise can clamp larger workpieces and provide sufficient clamping force, for parts with high dimensional accuracy, the bench vise clamp During the holding tim...

Embodiment 1

[0023] Such as figure 1 As shown, a component fixing device includes a bottom plate 7, a fixed block 1, a movable block 2 and a pushing device for pushing the movable block 2 to move toward the side of the fixed block 1. The bottom plate 7 is strip-shaped, and the The fixed block 1 is fixed on one end of the base plate 7, the pushing direction of the pushing device is along the length direction of the base plate 7, both sides of the base plate 7 are provided with chute 6 along the length direction of the base plate 7, and the movable card The block 2 is provided with two sliders that are respectively matched with different chute 6, the mating surface formed by the side of the chute 6 and the bottom surface of the slider is an arc surface, and in the depth direction of the chute 6, the The highest point of the arc surface is located between the opening end of the chute 6 and the bottom end of the chute 6; two chute 6s are provided on each side of the bottom plate 7, and the two...

Embodiment 2

[0028] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, as a simple implementation form of the pusher, the pusher includes a threaded rod 4, a threaded seat 3 and a handle 5, the threaded seat 3 is fixed on the bottom plate 7, and the threaded rod 4 is threaded with the threaded seat 3 , the axial direction of the threaded rod 4 is parallel to the length direction of the bottom plate 7, the turning handle 5 is fixed on the threaded rod 4, and the movable block 2 is located between the fixed block 1 and the pushing device. In the above structure, during the rotation of the threaded rod 4 , the end of the threaded rod 4 exerts a driving force on the movable block 2 , and the rotating handle 5 is used to drive the threaded rod 4 to rotate. In the above structure, the threaded seat 3 and the bottom plate 7 are detachably connected. Further, the fixed block 1 can be set in the form of a right-angle notch on it. The end face and the uppe...
