Description

Technical Field

[0001] The invention relates to the technical field of anchor processing, in particular to a double-end face cutting device for processing prestressed anchors. Background Art

[0002] Anchors, also known as prestressed anchors, are primarily used for prestressing concrete during construction. Commonly used in bridge construction, they are pre-installed and positioned before pouring concrete. These anchors are embedded in the concrete at both ends of the corrugated pipe, providing stability for the jacks during tensioning. During the anchor manufacturing process, the end faces must be machined to ensure a flat and even finish.

[0003] In the prior art, dual-end face cutting devices used for prestressed anchor machining are inconvenient when switching between anchor end faces, affecting machining efficiency. Furthermore, the devices are not stable enough when securing the anchor, and vibrations between the anchor and the cutting tool during machining can easily damage the tool. Furthermore, when switching between anchor end faces, the center point of the anchor shifts, reducing machining accuracy. Therefore, improvements to the prior art are needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a double-end face cutting device for prestressed anchor processing, which solves the problem of inconvenient end face switching during anchor processing, and also solves the problem of insufficiently stable anchor fixation and the problem of offset of the center point of anchor end face switching.

[0005] The top end of the support leg is connected with the support shaft by the spring, and the bottom end of the support leg is connected with the support shaft by the spring. The top of the support rod is provided with a toothed plate, and the bottom of the support rod is provided with a toothed plate, and the toothed plate is connected with the toothed plate at the bottom end.

[0006] Preferably, one end of the spring is in contact with and connected to the bottom plate, and the other end of the spring is in contact with and connected to the guide block.

[0007] Preferably, there are two limit pins, and the two limit pins are symmetrically distributed on the cross bar.

[0008] Preferably, a turntable is welded to the threaded rod, and a rocker is welded to the turntable.

[0009] Preferably, one end of the compression spring is in contact with a support ring, and the other end of the compression spring is in contact with a stopper.

[0010] Preferably, an annular groove is formed at one end of the pressing plate away from the threaded rod, a protrusion is provided on the clamping block, and the protrusion is slidably connected in the annular groove.

[0011] Preferably, a sliding groove is provided on the side plate, and a sliding rod is slidably connected in the sliding groove.

[0012] Preferably, a support is welded on the side plate, and a forward and reverse threaded screw rod is rotatably connected inside the support.

[0013] Preferably, a bushing is fixedly sleeved on the outer side of the forward and reverse threaded screw rod, and a handle is welded to the side wall of the bushing.

[0014] Preferably, one end of the disc spring is bonded to the side plate, and the other end of the disc spring is bonded to a centering shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention facilitates the movement of the support plate by arranging a guide block and a guide groove, and resets the support plate by arranging a spring. The support shaft is rotated to facilitate steering adjustment after one end of the anchor is processed. When the anchor is processed, the end face can be quickly switched, thereby improving processing efficiency.

[0017] 2. The present invention connects a threaded rod through a thread in the support ring, rotates the threaded rod to move the pressure plate, and the movement of the pressure plate drives the clamping block to move, thereby fixing the anchor. At the same time, by setting a limit pin and a limit groove, after the anchor is turned by rotating the cross bar, it is convenient to limit the anchor, thereby avoiding damage to the tool due to vibration during the anchor processing.

[0018] 3. The present invention opens an installation groove on the side panel, sets a centering shaft in the installation groove, and slides a conical block on the side panel to position the anchor through the cooperation of the conical block and the centering shaft, thereby ensuring that the center point position of the anchor remains unchanged after the end face is switched, avoiding errors and improving processing accuracy.
