Description

Technical Field

[0001] The utility model relates to the technical field of printing plate roller processing positioning equipment, in particular to a positioning clamp for printing plate roller processing. Background Art

[0002] The printing roller is one of the accessories of the offset printing machine. The roller is used for printing, while the spindle is used for power transmission. The high-speed printing roller is an assembly of the left and right supports and the cylinder body. The processing of the roller assembly hole, that is, the connection threaded hole between the support and the cylinder body and the positioning pin hole, is the production bottleneck of the entire roller. Although the traditional printing rollers on the market can clamp and fix the roller workpiece, the operation is relatively complicated, the workpiece is easy to shift during the processing, and it is inconvenient to adjust the angle of the workpiece accordingly during work. For this reason, we propose a positioning fixture for printing roller processing. Utility Model Content

An extension plate 23 is provided at the end of the outer shell 12, a telescopic rod 24 is provided on the top of the extension plate 23, a top plate 25 is provided on the top of the telescopic rod 24, and an upper limit block 26 is provided below the top plate 25.

[0019] By arranging an end plate 2 at the end of the outer shell 12, and arranging a hydraulic cylinder 21 and an abutment plate 22 inside the end plate 2, the position of the abutment plate 22 can be adjusted under the action of the hydraulic cylinder 21, so that the workpiece can be clamped and fixed from the end thereof under the action of the two abutment plates 22, and the height of the top plate 25 can be adjusted under the action of the telescopic rod 24, so that the upper limit block 26 can press and limit the workpiece from the top, thereby further ensuring the stability of the fixation of the workpiece and improving the use effect of the equipment.

[0020] In the above solution, casters 11 are provided at the bottom of the base 1. Specifically, the casters 11 are self-locking casters, and there are four casters, under the action of the casters 11, the device can be easily moved.

[0021] In the above scheme, the driven roller 14 and the driving roller 15 are both covered with anti-skid sleeves 16, and are both rotatably connected to the support frame 13 through bearings. The surface of the protective sleeve 16 is roughened to form anti-skid patterns, thereby achieving an effective anti-skid effect.

[0022] In the above scheme, the driving mechanism includes a reducer 17 that is transmission-connected to one end of the active roller 15, and a motor 18 is connected to the side of the reducer 17. The motor 18 is externally connected to a power supply and a control switch. When working, the motor 18 drives the active roller 15 to rotate through the reducer 17, and drives the workpiece to realize rotation adjustment above the equipment through the active roller 15.

[0023] In the above solution, buffer blocks 19 are distributed on the side of the active roller 15. Specifically, the buffer blocks 19 are elastic blocks made of silicone rubber, which can play a stable supporting effect on the one hand and a certain buffering effect on the other hand.

[0025] In the above scheme, the telescopic rod of the hydraulic cylinder 24 is rotatably connected to the abutment plate 22 through a connecting rod and a bearing. The piston rod of the hydraulic cylinder 24 drives the connecting rod to move, thereby driving the abutment plate 22 to approach the end of the workpiece to limit it, and in a fixed state, the workpiece can still be driven to rotate through the active roller 15, and the abutment plate 22 rotates accordingly.

[0026] Working principle:

[0027] When this positioning fixture for printing plate roller processing is used, the plate roller workpiece to be fixed is placed in the support frame 13 accordingly, so that the side wall of the plate roller workpiece is in contact with the driven roller 14, the active roller 15 and the buffer block 19 at the same time, thereby achieving stable support for the workpiece, and then the position of the top plate 25 is adjusted downward by the driven roller 14, so that the upper limit block 26 moves down and contacts the top of the workpiece, and then the hydraulic cylinder 21 is started, and the piston rod of the hydraulic cylinder 24 drives the connecting rod to move, thereby driving the abutment plate 22 to approach the end of the workpiece to limit and fix it. At this time, the upper and lower sides and the positions of the two ends of the workpiece are constrained, so that the workpiece can be stably limited. In the fixed state, the active roller 15 can still be driven to rotate by the motor 18 in cooperation with the reducer 17, and the workpiece is driven by the active roller 15 to realize rotation adjustment above the equipment. At this time, the abutment plate 22 rotates accordingly, which can meet the adjustment needs during the processing.
