Abstract

The utility model discloses a bolt processing fixing clamp for a numerical control lathe, which comprises an operation frame, wherein a pair of clamping jaw assemblies capable of sliding relatively are respectively arranged on two sides of the bottom of the operation frame, and the clamping jaw assemblies are connected and driven through a cylinder; a rotating shaft is vertically arranged at the center of the bottom side of the operating frame, a gear is arranged on the rotating shaft, a supporting rod is transversely arranged at the bottom side of the rotating shaft, and limiting rollers are arranged at the upper parts of two ends of the supporting rod; the claw assemblies on the two sides horizontally extend out of a rack which penetrates through the upper ends of the two sides of the supporting rod respectively to be in transmission with the gear. The clamping jaw assembly is driven by the air cylinder to move inwards or outwards at the same time, so that clamping or loosening actions in central symmetry are realized, the operation actions of the robot are more accurate and smooth, forced synchronization is performed by the gear and the rack of the clamping jaw assembly in order to ensure synchronous movement, and the rack can be prevented from deflecting outwards or downwards by the support rod and the limiting roller, so that meshing failure is avoided.

Description

Bolt machining fixing clamp for numerical control lathe

Technical Field

The utility model relates to the technical field of precision machining equipment, in particular to a bolt machining fixing clamp for a numerical control lathe.

Background

In accurate large-scale bolt manufacturing, in order to guarantee the precision, generally adopt numerical control lathe processing, the automatic clamp who utilizes the robot realizes the fixed and transfer etc. of part, traditional robot automation anchor clamps one end is fixed, then the relative stiff end motion of one end, in the in-process of operating like this, for example during the centre gripping, need the handling frame body in order to follow to move, otherwise will make the goods remove the back and just can the centre gripping, perhaps press close to the goods with the stiff end removal in advance, just can begin the clamping process, and firm for the centre gripping, the elasticity jack catch that generally all adopts, so the jack catch is undeformed when pressing close, and the stiff end jack catch warp when beginning the centre gripping, still can cause the goods removal in the clamping process.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a bolt processing and fixing clamp for a numerical control lathe, so as to solve the technical problems in the background technology.

The technical scheme of the utility model is as follows:

a bolt processing fixing clamp for a numerical control lathe comprises an operation frame, wherein a pair of clamping jaw assemblies capable of sliding relatively are arranged on two sides of the bottom of the operation frame respectively, and the clamping jaw assemblies are connected and driven through a cylinder; a rotating shaft is vertically arranged at the center of the bottom side of the operating frame, a gear is arranged on the rotating shaft, a supporting rod is transversely arranged at the bottom side of the rotating shaft, and limiting rollers are arranged at the upper parts of two ends of the supporting rod; the claw assemblies on the two sides horizontally extend out of a rack which penetrates through the upper ends of the two sides of the supporting rod respectively to be in transmission with the gear.

Furthermore, the jack catch subassembly comprises slide and the claw seat of bottom, installs two pairs of guide rails in the handling frame bottom symmetry, all installs a pair of slide with guide rail complex at the slide upside, and a plurality of finger claws are installed to claw seat downside, and the rack is all fixed in slide upside middle part.

Furthermore, the finger claw body is made of spring steel, is trapezoidal and expands outwards, and is provided with a cushion pad on the inner side.

Furthermore, a flange plate is arranged at the top end of the rotating shaft and fixed at the center of the bottom of the operating frame through bolts.

The utility model has the advantages that:

according to the utility model, the air cylinder is used for driving the jaw assemblies to simultaneously move inwards or outwards to realize the clamping or loosening action which is symmetrical about the center, so that the operation action of the robot is more accurate and smooth, the jaw assemblies on two sides are free ends, and therefore, in order to ensure the synchronous motion, the gear and the rack of the jaw assemblies are used for forced synchronization, and the support rod and the limiting roller can prevent the rack from deflecting outwards or downwards, so that the meshing failure is avoided.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-4:

a bolt processing fixing clamp for a numerical control lathe comprises an operation frame 1, wherein a pair of clamping jaw assemblies 2 capable of sliding relatively are arranged on two sides of the bottom of the operation frame 1 respectively, and the clamping jaw assemblies 2 are connected and driven through a cylinder 3; a rotating shaft 51 is vertically arranged at the center of the bottom side of the operating frame 1, a gear 5 is arranged on the rotating shaft 51, a support rod 52 is transversely arranged at the bottom side of the rotating shaft 51, limiting rollers 53 are arranged at the upper parts of two ends of the support rod 52, a flange plate 54 is arranged at the top end of the rotating shaft 51 for facilitating the installation of the gear 5, and the flange plate 54 is fixed at the center of the bottom of the operating frame 1 through bolts; the jaw assemblies 2 on both sides horizontally extend out a rack 4 which respectively penetrates through the upper ends of both sides of the support rod 52 to be in transmission with the gear 5.

According to the utility model, the cylinder 3 is used for driving the jaw assemblies 2 to simultaneously move inwards or outwards to realize the clamping or loosening action in central symmetry, so that the operation action of the robot is more accurate and smooth, the jaw assemblies 2 on two sides are both free ends, and therefore, in order to ensure the synchronous motion, the gear 5 and the rack 4 of the jaw assemblies 2 are used for forced synchronization, and the support rod 52 and the limiting roller 53 can prevent the rack 4 from deflecting outwards or downwards, so that the meshing failure is avoided.
